[0044] The vehicle lock device of the present invention comprises a lock assembly, a transmission device and a control device, wherein the lock assembly comprises a lock body and a lock body matching piece, the transmission device is connected to the lock assembly, the control device is connected to the transmission device, and the control device is configured to: in response to a locking operation, drive the lock body and the lock body matching piece to match through the transmission device; and in response to an unlocking operation, drive the lock body and the lock body matching piece to disengage through the transmission device. The specific structure of the lock assembly can be referred to Figure 1 , 2 and 3; the specific structure of the control device can be referred to Figure 4 , 5 As shown in Figure 6, the specific structure of the transmission device can be referred to Figure 1 and4 shown.

[0045] First reference Figure 1 and 4 One end of the transmission device 300 is connected to the lock assembly, and the other end is connected to the control device. In this embodiment, the transmission device 300 is a steel wire. The function of the transmission device is mainly to realize the transmission of force. Therefore, the steel wire in this embodiment can also be replaced by other connecting structures to realize the connection between the control device and the lock assembly, such as one or more connecting structures such as a pull rope, a spring, and a hinge.

[0046] Then, refer to Figure 1 , 2 3, which shows an implementation of the lock assembly of the present invention, the lock assembly has a lock body 140 and a lock body matching piece 160. In this embodiment, the lock body 140 is a lock plate, and the lock body matching piece 160 has a lock groove 161 accordingly. The lock body 140 functions as a locking device or equipment, and the lock body matching piece 160 cooperates with the lock body to lock the device or equipment. Therefore, the lock plate in this embodiment can also be replaced with other forms, such as a polyhedron, a cylinder, a sawtooth shape, or the head of the lock plate is equipped with other devices with a locking method, such as by cooperating with the lock body matching piece 160, the locking state is gradually achieved by friction to achieve locking. Similarly, the lock body matching piece 160 that cooperates with the lock body 140 can also be replaced with a structure corresponding to the above-mentioned lock body replacement structure. Of course, the lock body 140 can also be provided with a groove, so that the lock body matching piece 160 is provided with a protrusion that cooperates with the groove. In this embodiment, the lock body fitting 160 is fixedly arranged on the inner side of the first chain fork 400, and the lock body is installed on the second chain fork 401. Of course, the lock body fitting 160 can also be fixedly arranged on the inner side of the second chain fork 401, and the lock body is correspondingly installed on the first chain fork 400. In addition, the lock body 140 and the lock body fitting 160 can also be installed at other positions of the vehicle, such as the seat fork, etc., as long as the functions of the present invention are achieved.

[0047] The lock assembly also includes a fixing pin 150. The lock body 140 is provided with an active area 141 that cooperates with the fixing pin 150. The active area 141 can be an elongated hole or a slot. In the present embodiment, the active area 141 is a runway hole. It should be understood that the runway hole can also be replaced by holes or slots of other shapes. When the fixing pin 150 moves to one end 144 of the active area 141, the lock body 140 cooperates with the lock body matching piece 160. When the fixing pin 150 moves to the other end 145 of the active area 141, the lock body 140 and the lock body matching piece 160 are disengaged. The fixing pin 150 is fixedly arranged on the second rear chain stay 401. It should be understood that the fixing pin 150 that uses the lever principle to change the direction of the lock body 140 can also be arranged on the lock body 140. The active area 141 that cooperates with the fixing pin 150 is arranged on the second rear chain stay 401.

[0048] The lock body 140 is rotatably connected to the transmission device 300 at a first connection position 142. In the unlocked state, the lock body 140 and the transmission device 300 form an acute angle, preferably less than 30° (see Figure 3 ), in the locked state, the lock body 140 and the transmission device 300 are at right angles or approximately at right angles (see Figure 2 ).

[0049] The lock assembly also includes an elastic component 110 and a connecting member 120, wherein the connecting member 120 has a first end 121 and a second end 122 opposite to each other, wherein the first end 121 is rotatably connected to the lock body 140 at a second connection position 143 through a first axle pin 130, and the second end 122 is connected to the elastic component 110, wherein the first connection position 142 and the second connection position 143 are located on the same side of the active area 141, and the other end of the elastic component 110 is fixedly connected to the second rear chain stay 401. The elastic component 110 is a spring in this embodiment, and in the unlocked state, the spring is in a free state, and in the locked state, the spring is in a stretched state. It should be understood that the spring may also adopt other structures, such as a spring sheet, etc. The connecting member 120 may also be eliminated in other embodiments, that is, one end of the elastic component 110 is directly rotatably connected to the lock body 140 at the second connection position. The first axle pin 130 can be replaced by other structures when the elastic component 110 and the lock body 140 adopt other structures. In addition, the first axle pin 130 can also be directly set on the connecting member 120 or the lock body 140 without being set separately.

[0050] In addition to the rear chain fork given in this embodiment, the installation position of the lock assembly can also be installed on the rear seat fork or front fork, or other positions that do not affect the functioning of the lock assembly.

[0051] Next, refer to Figure 4 , 5 6, which shows an implementation of the control device of the present invention, the control device includes a trigger 210 and a bayonet 230, the trigger 210 and the bayonet 230 are movably connected, and the bayonet 230 is used to cooperate with the trigger 210 to realize the opening and locking of the lock assembly. In this embodiment, the trigger 210 is a handle with a lever function, and the trigger 210 rotates around the second axis pin 220, and the second axis pin 220 is set on the lower tube 240. The trigger 210 is provided with a guide surface 212 and a locking surface 211. In the locked state, the bayonet 230 cooperates with the locking surface 211 to lock the position of the trigger 210 and prevent the trigger 210 from rotating upward (i.e., rotating clockwise); in the unlocked state, the bayonet 230 cooperates with the guide surface 212 and can rotate around the second axis pin 220. In this embodiment, the trigger 210 is connected to the transmission device 300.

[0052] The function of the control device is to control the working state of the lock assembly through the transmission device. As the handle of the trigger 210, it is the main component that bears external force to lock and can be replaced by any other switch device with the function of transmitting power. The second shaft pin 220 is used to change the direction of the trigger 210. If the trigger 210 is replaced with other structures, the corresponding second shaft pin 220 appears in other forms, or the second shaft pin 220 is directly set on the trigger 210 without being set separately.

[0053] The control device also has a power mechanism (not shown in the figure), which can be set at a position close to the trigger member 210 or at other positions. The function of the power mechanism is to apply source power to the bayonet 230 to unlock, such as scanning a code to unlock. More specifically, when the control device is unlocked, the power mechanism drives the bayonet 230 to disengage from the locking surface 211, thereby allowing the trigger member 210 to rotate relative to the second shaft pin 220. The power mechanism that provides the source power can be a key, a motor, or other existing structures that can provide source power.

[0054] Final Reference Figure 7 and 8 , which shows an implementation of the bicycle of the present invention, and in particular shows the connection relationship between the various components of the bicycle lock device in the locked state and the unlocked state.

[0055] In the locked state, the lock body 140 and the lock body matching member 160 cooperate, and the lock body 140 is located between the adjacent spokes of the wheel so that the wheel cannot rotate. Figure 7 Transform to Figure 8 ), the control device receives the unlocking command, and the trigger member 210 drives the lock body 140 and the lock body matching member 160 to disengage through the transmission device 300; in the unlocking state, the lock body 140 and the lock body matching member 160 disengage, the lock body 140 is no longer located between the adjacent spokes of the wheel, and the wheel can rotate freely. Figure 8 Transform to Figure 7 ), the control device is operated to close the lock, and the trigger member 210 drives the lock body 140 and the lock body matching member 160 to match through the transmission device 300.

[0056] More specific unlocking (by Figure 7 Transform to Figure 8) The process is as follows: when an unlocking command is received, the motor will give the latch 230 a force to disengage it from the locking surface 211 of the trigger member 210, thereby disengaging it from the trigger member 210. When the latch 230 leaves the locking surface 211 of the trigger member 210, the elastic component 110 will drive the lock body 140 backward. Under the limitation of the fixing pin 150, the lock body 140 changes from a state of forming an angle of 90° with the transmission device 300 to a state of a small acute angle (the lock body 140 is no longer located between the wheel spokes), and the trigger member 210 will pop up to complete the unlocking.

[0057] More specific locks (by Figure 8 Transform to Figure 7 ) process is as follows: when locking, press the trigger member 210 downward (i.e. rotate the trigger member 210 counterclockwise) to make it cooperate with the corresponding groove of the vehicle body. During the pressing process, the latch 230 will use itself and the guide surface 212 of the trigger member 210 to move with the trigger member 210, and pop out when the trigger member 210 is pressed into place, limiting the lifting of the trigger member 210. The trigger member 210 and the lock body 140 are connected by the transmission device 300. When the trigger member 210 is pressed downward, it will drive the transmission device 300 forward, thereby pulling the lock body 140 forward. The middle active area 141 of the lock body 140 cooperates with the fixed pin 150. When the lock body 140 moves forward, since the lock body 140 and the transmission device 300 form an acute angle, there is a fixed pin 150 in the middle of the lock body 140 to block it. Therefore, the lock body 140 will be pulled by the transmission device 300 to form a right angle with the lock body 140. At this time, the lock body 140 cooperates with the lock body matching piece 160 to complete the locking.

[0058] In the above embodiments, the lock body 140 of the lock assembly can also be replaced by structures with other motion trajectories to achieve this switch lock state, such as a combination of one or more other easily conceivable linear motion structures and curved motion structures; the trigger member 210 of the control device can also be replaced by other operating methods to achieve the switch lock state, such as a combination of one or more structures of push, pull, button, key or rotation.

[0059] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in the field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
