[Functional Modules of Anti-Theft Lock]
FIG. 2 is a schematic view of functional modules of a bicycle anti-theft lock 30 provided by an embodiment of this disclosure. As shown in FIG. 2 , the anti-theft lock 30 comprises a CPU module 301 , a signal receiving/sending module 302 , a clock module 303 , a positioning module 304 , a vibration sensor module 305 , an alarm module 306 , a lock control module 307 and a memory 313 which are communicatively connected to the CPU module 301 , respectively, and a power supply module 308 for supplying electric power to the respective modules.
The CPU module 301 is a central processing unit of the anti-theft lock 30 , and is configured to control operations and the like of the respective modules of the anti-theft lock 30 , wherein the control refers to, for example, processing an instruction from the cloud calculator 2 and information and the like from the other modules of the anti-theft lock 30 , and sending control instructions and the like to other modules.
For example, the signal receiving/sending module 302 comprises an antenna, a buffer and the like described later, and may be connected to a wireless network to receive/send information from/to external equipment such as the mobile communication equipment 1 , the cloud calculator 2 and the like under the control of the CPU module 301 .
The clock module 303 provides time information for the CPU module 301 , so that the CPU module 301 , the mobile communication equipment 1 and the cloud calculator 2 can acquire current time information of the bicycle 3 . If it is not necessary to acquire the current time information of the bicycle 3 (for example, the time information of the bicycle is based on a lock time of the cloud calculator 2 ), the clock module 303 may be omitted. However, it is possible that the bicycle 3 may be in a variety of environments. For example, if the communication environment is poor while the bicycle is stolen, although the bicycle 3 may move to a communication environment later and the cloud calculator 2 may determine that the bicycle is stolen according to information sent from the anti-theft lock 30 , and the like, the specific time when the bicycle is stolen cannot be acquired. Therefore, preferably, the anti-theft lock 30 is provided with the clock module 303 which can store an actual time in a timely manner when the bicycle is stolen in the memory and send the time to the cloud calculator 2 and/or the mobile communication equipment 1 immediately or later, so that an appropriate anti-theft strategy may be taken. The clock module 303 may also be integrated in the CPU module 301 as required.
For example, the positioning module 304 may be a GPS module, a Beidou satellite positioning module or the like, and is capable of collecting current location information (hereinafter referred to as positioning information) and reporting the same to the CPU module 301 ; and under the control of the CPU module 301 , the positioning information may be sent to external equipment such as the mobile communication equipment 1 and/or the cloud calculator 2 via the signal receiving/sending module 302 .
For example, the vibration sensor module 305 may be one of various sensors for detecting vibration, such as an acceleration sensor, and may be a sensor as long as it is capable of detecting vibration and providing information such as vibration intensity for the CPU module 301 , so that it is not limited to the acceleration sensor.
For example, the alarm module 306 may issue an on-site alarm by issuing a sound and/or light alarm/alarms after receiving an alarm instruction signal from the CPU module 301 . It should be noted that as the anti-theft system provided by the embodiment of this disclosure has functions of positioning and tracking a bicycle, the alarm module 306 configured to issue an on-site alarm is not an essential component for the anti-theft system provided by the present invention.
The lock control module 307 is configured to unlock the lock pin of the anti-theft lock 30 according to an instruction of the CPU module 301 , monitor locking state information (a locking state and an unlocking state) of the anti-theft lock 30 , and report the information to the CPU module 301 .
The memory 313 is configured to store the time information supplied by the clock module 303 to the CPU module 301 and the positioning information supplied by the positioning module 301 to the CPU module 304 , and may store the vibration intensity information supplied by the vibration sensor module 305 to the CPU module 301 as required.
The power supply module 308 comprises a battery and the like described later, and can supply electric power to the various electronic modules described above. It should be noted that in embodiments to be described later, the power supply module 308 may comprise the battery as an electric power storage device; or in a case that the electric power can be supplied from the outside in real time, for example, electric power is generated via solar energy, the battery in the power supply module may be omitted, and the power supply module is implemented via a combination of a photovoltaic element, a capacitor and the like. In addition, in FIG. 2 , the power supply module 308 is electrically connected to the CPU module 301 to supply electric power to the other modules via the CPU module 301 , or may be electrically connected to each module directly to supply electric power to the same.
It should be noted that all of the modules shown in FIG. 2 may be integrated with the lock as a whole like an embodiment described below, or part of the modules, as separate vehicle-mounted electronic equipment (anti-theft monitoring equipment), may be arranged outside the lock as long as required related information receiving and sending among the modules and the lock can be realized through a necessary circuit. For example, except for the motor assembly, the location sensor and the like described later in the lock control module 307 , which must be mounted in the anti-theft lock, other components may be arranged outside the lock as the separate vehicle-mounted electronic equipment (anti-theft monitoring equipment).
[Anti-Theft System]
An anti-theft method of the anti-theft system provided by an embodiment of this disclosure will be described below. FIG. 10 is a flow chart of the anti-theft method provided by an embodiment of this disclosure.
First, the CPU module 301 periodically performs self-awakening according to a preset period (S 101 ) and awakes the lock control module 307 to inquire about current state information of the anti-theft lock (S 102 ).
If the lock control module 307 returns a signal indicating that the anti-theft lock is in the unlocked state (“unlocking” in S 103 ) to the CPU module 301 , the CPU module 301 considers that the bicycle is being used normally, so that a first sleep mode is activated to instruct the signal receiving/sending module 302 , the clock module 303 , the positioning module 304 , the alarm module 306 and the lock control module 307 to enter the sleep state, and the CPU module also enters the sleep mode; and the CPU module ignores or shields a vibration detection signal from the vibration sensor module 305 (S 104 ), and waits for a next awakening period (S 101 ). Therefore, when the bicycle is normally used, electric power can be saved as the modules are in the sleep mode.
If the lock control module 307 returns a signal indicating that the anti-theft lock is in the locked state (“locking” in S 103 ) to the CPU module 301 , the CPU module 301 activates a second sleep mode to instruct the signal receiving/sending module 302 , the clock module 303 , the positioning module 304 , the alarm module 306 and the lock control module 307 to enter the sleep state, and the CPU module also enters the sleep mode; however, the CPU module 301 does not ignore or shield the vibration detection signal from the vibration sensor module 305 (S 106 ).
In this case, when detecting a vibration (“Yes” in S 107 ), the vibration sensor module 305 sends the vibration detection signal to the CPU module 301 , and the CPU module 301 is awakened based on the vibration detection signal, then acquires vibration intensity information in the vibration detection signal (S 108 ), and determines whether the vibration intensity exceeds a preset threshold value α or not (S 109 ).
If the vibration intensity does not exceed the preset threshold value α, it is considered that the vibration is not caused by a destructive behavior, and may be generated only through occasional slight shaking, so the CPU module returns to the second sleep mode (“Not” in S 109 ).
If the vibration intensity exceeds a preset threshold α (“Yes” in S 109 ), it is considered that the vibration is caused by a severe destructive behavior, so the CPU module awakes all the modules, collects positioning information, current time information and the like continuously or intermittently at a preset time interval (S 110 ), and instructs the alarm module 306 to alarm (S 111 ). Meanwhile, the CPU module detects whether or not it is possible to communicate with external equipment such as the cloud calculator 2 and/or the mobile communication equipment 1 (S 112 ) via the signal receiving/sending module 302 . If it is feasible to communicate (“Yes” in S 112 ), the CPU module reports the collected positioning information and current time information to the external equipment such as the cloud calculator 2 and/or the mobile communication equipment 1 (S 113 ). If it is temporarily infeasible to communicate (“Not” in S 112 ), the CPU module stores the collected positioning information, current time information, and the like in the memory (S 114 ); and the CPU module detects whether it is feasible to communicate with the external equipment such as the cloud calculator 2 and/or the mobile communication equipment 1 continuously or intermittently at a preset time interval (S 112 ). If it is detected that the communication is feasible (“Yes” in S 112 ), the stored positioning information and current time information are reported to the external equipment such as the cloud calculator 2 and/or the mobile communication equipment 1 (S 113 ). In addition, in step S 110 , the vibration intensity information may also be collected continuously; in step S 114 , the vibration intensity information may be stored; and in step S 113 , the collected vibration intensity information may also be reported to the external equipment such as the cloud calculator 2 and/or the mobile communication equipment 1 .
The CPU module 301 is controlled by a series of instructions to perform the anti-theft monitoring method according to the embodiment of this disclosure. Those instructions may be stored in the memory 313 , or in another memory device.
[Specific Embodiments of Anti-Theft Lock]
FIGS. 3-9 show specific embodiments of an anti-theft lock 30 .
For facilitating illustration, a state shown in FIG. 3 (A) is used as a reference. The width direction of the anti-theft lock 30 is defined as a left-right direction, the height direction of the anti-theft lock 30 is defined as an up-down direction, and the thickness direction of the anti-theft lock 30 is defined as a front-rear direction. In addition, sometimes, the surface of the anti-theft lock shown in FIG. 3 (A) may be referred to as the front surface or the front, and the surface of the anti-theft lock shown in FIG. 3 (B) may be referred to as the back surface or the rear surface.
[About the Case]
FIG. 3 is a schematic view of an overall appearance of an anti-theft lock 30 , wherein FIG. 3 (A) is a front view of the anti-theft lock 30 , and FIG. 3 (B) is a rear view of the anti-theft lock 30 . FIG. 4 is a perspective view of the anti-theft lock 30 .
As shown in FIG. 3 (A), the anti-theft lock 30 in this embodiment is a horseshoe-shaped lock. A case 309 of the anti-theft lock is horseshoe-shaped integrally, and comprises a lock body portion and side arm portions extending from left and right sides of the lock body portion respectively to form a substantially C-shaped lock opening. A lock mounting hole 3094 for mounting the anti-theft lock 30 to a bicycle or the like is formed in the center of the top of the lock body portion. For example, through the hole, the anti-theft lock may be fitted over a frame tube of the bicycle.
A positioning module mounting portion is arranged below the lock mounting hole 3094 ; and a GPS protection cover 3043 is mounted at the positioning module mounting portion, and the GPS module 3042 and the like described later are accommodated in the GPS protection cover. Referring to FIG. 4 , the lock mounting hole 3094 , the GPS protection cover 3043 and peripheral portions thereof form a stage in the shape of a trapezoid with oblique sides (hereinafter referred to as a trapezoid stage 3095 ) whose portions are more protruded forwards than other portions of the front surface of the case 309 and in which the projection areas in the front surface are gradually reduced. Moreover, according to the design, after mounting, the front surface and side surfaces of the GPS protection cover 3043 are smoothly transitioned with the other portions of the trapezoid stage 3095 . Therefore, after the GPS protection cover 3043 is fixed to the case 309 as described later, it is not easy to open the GPS protection cover 3043 , so that the anti-theft lock is well protected from destroy. In addition, a light guide hole 3105 for exposing a light guide post 3063 described later is formed in a position near the bottom of the GPS protection cover 3043 .
Returning to FIG. 3 (A), an annular lock portion of the horseshoe-shaped lock is arranged below the trapezoid stage 3095 , and is in a form of a C-shaped opening which opens downwards. Referring to FIG. 7 described later, a C-shaped lock groove 312 is formed inside the annular lock portion of the case. In addition, a slide hole for guiding a lock pin handle 3079 to slide is further formed in one side arm of the annular lock portion.
Moreover, referring to FIG. 5 , a window 3093 is formed in the side wall of one side (the right side in this embodiment) in the left-right direction of a face case 3091 . In order to improve the destruction resistance of the anti-theft lock 30 , preferably, the case 309 of the anti-theft lock 30 may be made of a metal material such as stainless steel. As the metal case will shield or overly block radio signal receiving and sending of the signal receiving/sending module 302 (an antenna 3021 ) accommodated in the case, the window 3093 is formed to reduce the influence of the case 309 on signal receiving and receiving of the antenna 3021 .
In addition, as shown in FIG. 3 (B), a sound alarm hole 3096 is formed in the back surface of the case 309 , and corresponds to a sound transmission hole 3104 in the battery compartment housing 310 described later.
[About the Internal Components]
FIG. 5 is a schematically exploded view of all components of the anti-theft lock 30 . As shown in FIG. 5 , the anti-theft lock 30 comprises: a case constituted of a face case 3091 and a bottom case 3092 ; a battery compartment housing constituted of an upper battery compartment cover 3101 and a lower battery compartment cover 3102 ; a battery 3081 accommodated in the battery compartment housing; a PCB 311 accommodated in the battery compartment housing and integrated with the above-described CPU module 301 , the signal receiving/sending module 302 , the clock module 303 , the vibration sensor module 305 , the sound alarm module 3061 , and a part of the lock control module 307 (a motor driver not shown in FIG. 5 ) thereon; a tongue 3071 ; a spring 3078 connected to the tongue 3071 ; location sensors for a first limit switch 3072 A and a second limit switch 3072 B distributed on the left side and the right side of the tongue 3071 respectively; a motor assembly constituted of a motor 3077 for supplying power to the tongue 3071 to enable the same to move, a sealing gasket 3076 mounted at the side of an output shaft of the motor 3077 , and a motor box 3075 for accommodating the motor 3077 and the sealing gasket 3076 ; a crank member 3074 which is connected to the output shaft of the motor 3077 and rotates together with the same; a tension spring 3073 A and a lock pin 3073 B which are accommodated in the C-shaped lock groove 312 formed in the lower portion of the case; a lock pin handle 3079 connected to the lock pin 3073 B and exposed outside the case; another sealing gasket 3041 ; a GPS circuit board 3042 integrated with a GPS module and a light alarm module thereon; a GPS protection cover 3043 ; and a light guide post 3063 .
[About the Battery Compartment]
FIG. 6 is a schematically perspective view of a shape and structure of a battery compartment housing 310 according to an embodiment of the present embodiment. As shown in FIG. 6 , the battery compartment housing 310 is formed by joining the upper battery compartment cover 3101 and the lower battery compartment cover 3102 via a bolt, and a sealing ring 3103 (referring to FIG. 5 ) is arranged along the circumference of the joining portion, so that a waterproof and dustproof closed space is formed internally as a battery compartment for accommodating the battery 3081 and the PCB 311 . Of course, the upper battery compartment cover 3101 and the lower battery compartment cover 3102 may also be jointed through clamping, bonding, riveting or the like.
In the present embodiment, the battery compartment housing 310 is mounted in a space between the lock mounting hole 3094 and the C-shaped lock groove 312 in the case 309 in the up-down direction, and forms concave portions corresponding to the lock mounting hole 3094 and the C-shaped lock groove 312 respectively in position in a way of bypassing the lock mounting hole 3094 and the C-shaped lock groove 312 (referring to FIG. 7 ). As shown in FIG. 6 , the thickness of the battery compartment housing 310 is inconsistent, and the battery compartment housing comprises a thin housing portion with a smaller thickness and a thick housing portion with a larger thickness. An inner space of the thin housing portion is relatively shallower, and an inner space of the thick housing portion is relatively deeper; and the transition between the thin housing portion and the thick housing portion is stepped.
In addition, a wire outlet hole 3107 allowing a power supply wire to pass through is further formed in the thin housing portion of the battery compartment housing 310 . A wire of the PCB 311 is led out from the wire outlet hole 3107 to be connected to a motor and a location sensor described later so as to supply electric power to them and send and receive control signals. As the wire outlet hole 3107 is formed in the thin housing portion of the upper battery compartment cover 3101 , and a motor assembly and the location sensor of the lock control module described later are arranged at the thin housing portion of the upper battery compartment cover 3101 , the wire outlet hole, the motor assembly and the location sensor are made closer in arrangement, reducing the length of the wire, and further compacting the layout of the components. In addition, wire inlet holes 3108 (referring to FIG. 5 ) are formed in the case 309 (the bottom case 3092 ) and the battery compartment housing 310 (the lower battery compartment cover 3102 ) and correspond to the lock mounting hole in position. Through the wire inlet holes, a power supply wire and the like used in charging of, for example, a battery 3081 can be led into the battery compartment from the outside of the case. Because the anti-theft lock can be mounted on a frame tube of a bicycle in a sleeving manner via the lock mounting hole, after a wire leading hole opposite to the wire inlet holes 3108 of the anti-theft lock is drilled at a corresponding position of the frame tube, wires can be hidden inside the frame tube to realize wiring, and thus are prevented from being destroyed easily, greatly improving the safety of the anti-theft lock.
Referring to FIG. 5 and FIG. 7 (B), a slot 3105 is arranged at upper middle portions of the inner sides of the left and right side walls of the battery compartment housing 310 , and the PCB 311 is inserted in the slot 3105 in a manner that a normal of the PCB is substantially parallel to the front surface of the lock. Moreover, the change of the width of the PCB 311 in the front-rear direction corresponds to that of the thickness of the battery compartment housing 310 ; that is, the width of the portion of the PCB 311 located at the thick housing portion in the front-rear direction is relatively larger, while the width of the portion of the PCB located at the thin housing portion in the front-rear direction is relatively smaller. In addition, in this embodiment, the battery 3081 is, for example, a lithium ion battery, and is substantially cuboid-shaped; the largest surface (hereinafter also referred to as the maximum surface) in six surfaces of the cuboid and the surface of the PCB are fixed in the thick housing portion of the battery compartment housing 310 in a manner that the maximum surface is substantially parallel to the surface of the PCB.
Generally, in order to ensure that the PCB has an enough space to mount all of the modules, the reduction of the PCB area is limited; and moreover, in order to ensure an adequate battery capacity, the reduction of the battery pack size is also limited. Therefore, if the PCB and the substantially cuboid battery pack are mounted in an anti-theft lock in a manner that the surface of the PCB is parallel to the largest surface of the battery pack, although the overall thickness of the anti-theft lock is unchanged, a front area of the anti-theft lock must be increased. In a case that a lock front area occupied by the C-shaped lock groove 312 and the lock mounting hole 3094 is not reduced, requirements on the mounting of the PCB and the battery pack can be met only by increasing an area in the height direction (up-down direction) or the width direction (left-right direction) of the lock. As a result, the anti-theft lock looks huge, affecting the beauty and possibly the mounting of the anti-theft lock. In an embodiment of this disclosure, a space in the thickness direction of the anti-theft lock is fully utilized, so that the surface of the PCB and the largest surface of the battery are inserted in the space between the C-shaped lock groove 312 and the lock mounting hole 3094 in a manner that the surface of the PCB and the largest surface of the battery are perpendicular to the front of the lock. In this way, the front area of the lock will not be increased excessively, and the lock looks more beautiful and is easy to mount.
In addition, by providing the battery compartment housing with the thin housing portion and the thick housing portion, the battery and the main portion of the PCB can be mounted in the thick housing portion as described above, and the mounting space of the battery and the PCB is ensured; and meanwhile, the motor assembly, the tongue, the location sensor and the like described later can be mounted in an outside space of the thin housing portion. Thus, all of the modules can be compactly arranged in a limited space of the case 309 , reducing the overall size of the anti-theft lock.
In addition, a protrusion portion 3107 as shown in FIG. 7 (A) is formed in a side wall portion, corresponding to the window 3093 of the case 309 , of the battery compartment housing 310 , and is matched with the window 3093 in shape, so the protrusion portion 3107 is tightly embedded in the window 3093 . In order to ensure the overall strength and the like, the battery compartment housing 310 may be made of a hard metal, a hard plastic, or the like, but at least, the protrusion portion 3107 is made of a hard material that does not substantially affect the signal receiving and sending of the antenna 3021 .
[About the Alarm Module]
Referring to FIG. 5 , in the present embodiment, the alarm module 306 comprises a sound alarm module 3061 (e.g., a buzzer and a driver thereof) capable of generating a sound alarm, and a light alarm module (e.g., an LED module and a driver thereof which are not shown in the Figure) capable of emitting a light alarm. A sound transmission hole 3104 is formed in the battery compartment housing 310 (it is formed in the lower portion of the lower battery compartment cover 3102 in the present embodiment) and corresponds to the mounting position of the sound alarm module 3061 ; and a waterproof sound transmission film is adhered to the sound transmission hole, so that not only is transmission of alarm sound free from influence, but also dust, water and the like are prevented from entering into the battery compartment through the sound transmission hole 3104 .
In addition, the light alarm module is mounted on the GPS circuit board 3042 , is communicably connected to the CPU module 301 through a pin 3044 arranged on the GPS circuit board 3042 described later, and is capable of emitting the light alarm under the control of the CPU module 301 . Moreover, a light guide hole 3043 (referring to FIG. 4 ) is formed in a GPS protection cover 3043 described later, and a light guide post 3063 is exposed out of the GPS protection cover 3043 from the light guide hole 3105 (referring to FIG. 3 (A)), so that light emitted from the LED is guided out of the anti-theft lock.
By arranging the light alarm module on the GPS circuit board near the outer surface of the anti-theft lock, the length of a path traveled by light which is emitted by the LED and is guided from the inside of the anti-theft lock to the outside is shortened, ensuring the brightness of the light alarm and simplifying a circuit wiring design.
It should be noted that in the present embodiment, both the sound alarm module 3061 and the light alarm module are provided; or one of them may be provided as required. Alternatively, as the anti-theft system of the embodiment has other anti-theft strategies as described above, the anti-theft lock 30 may not be provided with the alarm module 306 .
[About the Signal Receiving/Sending Module]
The signal receiving/sending module 302 is integrated on the PCB 311 . Referring to FIGS. 5 and 8 , an antenna 3021 is arranged on the PCB 311 and close to the window 303 of the case 309 . Therefore, when signal receiving/sending is performed between the antenna and the mobile communication equipment 1 as well as the cloud calculator 2 through a wireless network, poor information receiving/sending caused by a fact that the signal is shielded or blocked by the case 309 or the battery compartment housing 310 is avoided.
[About the Positioning Module]
In the present embodiment, a GPS module is adopted as the positioning module 304 . Referring to FIG. 5 , as described above, the GPS protection cover 3043 is in a form of a trapezoid stage with oblique sides. After the GPS circuit board 3042 is accommodated inside the GPS protection cover, the GPS protection cover attached with a sealing gasket 3041 is buckled at a positioning module mounting portion at the front surface side of the face case 3091 , and is fixed to the face case 3091 via clamping, bonding, bolting, riveting or the like. Preferably, the GPS protection cover is made of a hard material (which cannot be easily damaged) which does not substantially affect the receiving of a GPS signal. Therefore, the GPS circuit board 3042 is sealed in a closed space surrounded by the GPS protection cover 3043 and the sealing gasket 3041 in a waterproof and dustproof manner, so that it is ensured that the GPS signal can be received, and the GPS circuit board 3042 is protected from damage. In addition, a pin 3044 of the GPS circuit board 3042 passes through pin through holes 3106 (referring to FIG. 5 and FIG. 7 (A)) formed in corresponding positions of the sealing gasket 3041 , the face case 3091 and the battery compartment housing 309 (particularly, the upper battery compartment cover 3101 ) to be inserted into a connector arranged on the PCB 311 , so that the GPS module and the light alarm module which are located on the GPS circuit board can communicate with the CPU module 301 on the PCB 311 .
[About the Lock Control Module]
FIG. 7 is a schematic view of an internal structure of the anti-theft lock 30 according to the embodiment of the present embodiment, wherein (A) is a front view of the anti-theft lock after removing the face case 3091 , the sealing gasket 3041 , the GPS circuit board 3042 and the GPS protection cover 3043 , and (B) is a rear view of the anti-theft lock after removing the bottom case 3092 . FIG. 8 is a front view the anti-theft lock after removing the face case 3091 , the upper battery compartment cover 3101 , the sealing gasket 3041 , the GPS circuit board 3042 and the GPS protection cover 3043 when viewed from the front right side.
A mechanical part of the anti-theft lock provided by an embodiment of this disclosure comprises a lock pin provided with a retaining groove and configured to open or close a lock opening through movement thereof to enable the lock to be unlocked or locked, a tongue configured to stop or release movement of the lock pin by entering or exiting from the retaining groove of the lock pin, a first force application member for endowing the lock pin with a force allowing the same to move in the locking direction, and a second force application member for endowing the tongue with a force allowing the same to move in the direction of entering the retaining groove of the lock pin.
The lock control module comprises: a motor driver configured to receive an instruction signal from a CPU module to control the rotation of an output shaft of a motor assembly; the motor assembly configured to enable the output shaft to rotate according to a driving signal from a motor driver; the output shaft connected to the motor assembly; a tongue driving member configured to convert a rotational driving force of the motor assembly into a driving force allowing the tongue to move out of the retaining groove of the lock pin; and a location sensor configured to detect the location of the tongue and output a signal indicating the location of the tongue to the CPU module.
Particularly, in this embodiment, the anti-theft lock 30 is horseshoe-shaped; and the locking pin 3073 B is annular, and moves along an annular lock groove 312 formed in the case 309 to open or close the lock opening so as to enable the lock to be unlocked or locked.
The tongue 3071 is configured to stop or release the movement of the lock pin 3073 B along the C-shaped lock groove 312 by entering or exiting from the retaining groove of the lock pin 3073 B. Referring to FIG. 8 , a driving hole allowing a convex handle of the crank member 3074 to extend into is formed in the middle of the tongue 3071 .
In this embodiment, the first force application member is a tension spring 3073 A whose one end is fixed in the lock groove 312 and the other end thereof is connected to a non-lock opening end of the lock pin 3073 B, and is configured to endow the lock pin 3073 B with a force to pull the lock pin towards the unlocking direction. Of course, in a variation embodiment, for example, the first force application member adopts a spring whose one end is fixed in the lock groove 312 and the other end thereof endows the lock pin 3073 B with an elastic force to cause the same to move in the locking direction. That is, during locking, a lock opening end of the lock pin 3073 B closes the lock opening and compresses the spring, and the spring generates a force to rebound the lock pin. Thus, when the tongue moves out of the retaining groove, the force of the spring is released to eject the lock pin, so that the lock opening is opened. Besides, this function may be achieved via other manners.
In addition, referring to FIG. 5 , in this embodiment, the motor assembly comprises a motor 3077 for supplying a power source to the tongue 3071 to allow the same to move, a sealing gasket 3076 mounted at the output shaft side of the motor 3077 , and a motor box 3077 for accommodating the motor 3077 and the sealing gasket 3076 inside the motor box 3075 . By providing the sealing gasket 3077 and the motor box 3075 with respect to the motor 3077 , the dustproof and waterproof motor assembly can be formed to improve the environmental resistance of the anti-theft lock. The motor assembly is driven by a motor driver (not shown in the Figure) mounted on the PCB 311 to enable the output shaft to rotate.
In an embodiment of this disclosure, the tongue driving member may be of a crank structure. Referring to FIG. 5 , one end of the crank member 3074 is connected to the output shaft of the motor assembly, and the other end thereof is provided with the convex handle inserted into the driving hole formed in the tongue. When the output shaft of the motor assembly rotates, the convex handle is driven to rotate along a circular trace using an eccentric distance as the radius. In addition, of course, the tongue driving member is not limited to the crank structure of the present embodiment, may be of any structure as long as it can convert a rotational driving force of the motor assembly into a driving force allowing the tongue to move out of the retaining groove of the lock pin, or may adopt any transmission mode, such as a worm structure or the like.
The driving hole is formed in the tongue 3071 as described above, and a stopper is formed in the driving hole. The driving hole is formed to realize the following unlocking and locking processes.
Unlocking Process
When the tongue 3071 is in the retaining groove of the lock pin, the convex handle of the crank member is in a standby state at a non-stopper position in the driving hole. When the lock is to be opened, the convex handle of the crank member is rotated to the stopper position in the driving hole and is stopped by the stopper, and the convex handle continues to rotate against the stopper, so that the tongue 3071 is driven to move in the direction of moving out of the retaining groove, and the spring 3078 which endows the tongue 3071 with the force to allow the same to enter the retaining groove of the lock pin 3073 B is compressed. When the convex handle continues to rotate and then bypasses the stopper, the tongue 3071 loses a force allowing it to move out of the retaining groove, so the tongue moves in a direction of entering the retaining groove of the lock pin under the force of the spring 3078 till it is propped against the lock pin. Here, the lock pin is already in the unlocked state under the action of the tension spring 3073 A, and the retaining groove is moved to a position not corresponding to the tongue, so the tongue is propped against the non-retaining groove part of the locking pin; and at the time, the convex handle of the crank member is rotated to a first position in a standby state.
Locking Process
When the latch pin 3073 is pulled to the locking direction, the retaining groove is moved to the position corresponding to the tongue 3071 along with the movement of the lock pin 3073 B, and the tongue 3071 enters the retaining groove under the thrust of the spring 3078 to stop the movement of the lock pin 3073 B, so that the locking process is completed.
To achieve the above processes, the driving hole may take any of various shapes. For example, in the present embodiment, the driving hole is substantially b-shaped, and the top of the right semicircle of the b-shaped driving hole corresponds to the stopper. For example, the middle position of a connection portion between the right semicircle of the b-shaped driving hole and a vertical line serves as the first position, and the convex handle is in a standby state at this position (hereinafter also referred to as the first position). In the unlocking process, when rotating anticlockwise to the top (the stopper) along the right semicircle of the b-shaped driving hole from the bottom up, the convex handle drives the tongue to move upwards (in a direction of moving out of the retaining groove) while being propped against the stopper; when the convex handle reaches a threshold position (hereinafter also referred to as a second position) where it will bypass the stopper, the tongue reaches the maximum position in an upward moving direction (the direction of moving out of the retaining groove), then the convex handle bypasses the stopper to enter a vertical portion of the b-shaped driving hole, and the tongue loses a force for propping it upwards, so that the tongue moves downwards (in a direction of entering the retaining groove) under the thrust of the spring 3078 to be propped against the lock pin; and here, the convex handle stops rotating or moves to the first position so as to be in standby state.
FIG. 9 shows schematic views of exemplary shapes of a driving hole. The b-shaped driving hole may be in a shape of an approximately three-quarter circle as shown in FIG. 9 (A), or an approximately three-quarter prolate ellipse as shown in FIG. 9 (B) as long as the diameter of the circle or minor axis of the prolate ellipse is not less than the diameter of the circular rotation trace of the convex handle. In addition, instead of using the b-shaped driving hole, a protrusion arranging in the approximate circle as shown in FIG. 9 (C) may serve as the stopper. Therefore, the shapes of the driving hole are various, and the driving hole in any shape may be available as long as it can cooperate with the crank member to realize the above unlocking and locking processes.
In addition, in the present embodiment, location sensors 3072 for detecting the location of the tongue 3071 comprise a first limit switch 3072 A and a second limit switch 3072 B located at the left and right sides of the tongue 3071 , respectively. The two limit switches may be implemented through pressure sensors. Particularly, referring to FIG. 7 (A), a first limit piece 3071 A and a second limit piece 3071 B are arranged at both sides of the tongue 3071 along its moving direction, and located at staggered positions. The first limit switch 3072 A and the second limit switch 3072 B are arranged at positions corresponding to the first limit piece 3071 A and the second limit piece 3071 B, respectively. When the tongue 3071 enters the retaining groove in the lock pin 3073 B, the first limit piece 3071 A is propped against the first limit switch 3072 A to trigger the first limit switch 3072 A to generate a first limit signal to be reported to the CPU module 301 . Thus, the CPU module 301 is informed that the anti-theft lock is in the locking state currently; and here, the second limit piece 3071 B is separated from the second limit switch 3072 B, so the second limit piece will not trigger the second limit switch to generate a limit signal.
When unlocking is required, the CPU module 301 instructs the motor driver to drive the motor assembly to rotate; the tongue 3071 is driven by the crank member to move out of the retaining groove; here, the two limit pieces move along with the movement of the tongue, and the first limit piece 3071 A is separated from the first limit switch 3072 A; and when the tongue 3071 continues to move to reach or approach the maximum movement distance point, the second limit piece 3071 B is propped against the second limit switch 3072 B to trigger the same to generate a second limit signal to be reported to the CPU module 301 . Thus, the CPU module 301 is informed that the anti-theft lock is in the locking state currently, and instructs the motor driver to stop driving the motor. Here, the convex handle, connected to the output shaft of the motor, of the crank member stops moving in the inertia effect after reaching the second position. Alternatively, after receiving the second limit signal, the CPU module 301 may instruct the motor driver to drive the motor to rotate continuously for a preset time period, so that the convex handle can be rotated back to the first position.
In the above embodiment, the combination of the pressure sensors and the limit pieces on the tongue is taken as an example to illustrate the detection of the unlocking and locking states, but the present invention is not limited thereto. It is also possible to realize the detection of the unlocking and locking states by various manners, for example, by a combination of laser sensors and location markers on the tongue, or by arranging a distance measurement sensor in the moving direction of the tongue to measure a distance between the tongue and the distance measurement sensor to trigger a location detection signal.
The anti-theft lock provided by an embodiment of this disclosure is illustrated by taking a horseshoe-shaped lock for a bicycle as an example, but obviously, the form of the anti-theft lock is not limited to the horseshoe-shaped lock, and may be any lock which is provided with a lock opening and a lock pin and capable of realizing locking and unlocking by moving the lock pin to close or open the lock opening. Of course, the anti-theft lock can be used not only for bicycles but also for any object which needs to be locked.
