[0058] Example 4

[0059] This embodiment shows an implementation of a vehicle lock device, which may include any of the lock body matching devices in Embodiments 1-3 or their equivalents. This embodiment uses the lock body matching device in Embodiment 1 as an example. Figure 2-3 As shown, the vehicle lock device includes a lock body matching device and a lock body 4, and the lock body matching device is embodiment 1 ( Figure 1The lock body 4 comprises a lock housing 43, a motor 41 and a lock rod 42, wherein the motor 41 is located in the lock housing 43, the lock rod 42 is connected to the motor 41, a part of the lock rod 42 is located in the lock housing 43, and another part is located outside the lock housing 43.

[0060] Figure 2 The figure shows the relationship between the lock body matching device and the lock body when the vehicle lock device is in the locked state. At this time, the lock body matching part 11 is in the first position, the lock rod 42 is embedded in the lock slot 11, and the lock body matching part 1 cannot move between the first position and the second position. More specifically, the lock body matching part cannot move up and down. When the lock body device needs to be unlocked, the lock body 4 receives the unlocking instruction, and the motor 41 of the lock body 4 drives the lock rod 42 to move rightward to disengage from the lock slot 11, thereby releasing the restriction of the lock rod 42 on the upward and downward movement of the lock body matching part 1. Then, the trigger part is opened under the action of a clockwise external force. During this process, the trigger part drives the outer turntable to rotate, and the outer turntable drives the lock body matching part to move downward to the second position to complete the unlocking. At this time, the vehicle lock device is in the unlocked state. Specifically, Figure 3 shown.

[0061] Figure 3 The figure shows the relationship between the lock body matching device and the lock body of the vehicle lock device in the unlocked state. At this time, the lock body matching member 1 is in the second position, the lock rod 42 is out of the lock slot 11, and the lock body matching member 1 can move between the first position and the second position. More specifically, the lock body matching member can move up and down. When the lock body device needs to be locked, the trigger member is reset to the position as shown in the figure under the action of the counterclockwise external force. Figure 2 In this process, the trigger member drives the outer turntable to rotate, and the outer turntable drives the lock body matching member to move upward to the first position, and then the motor of the lock body drives the lock rod to move rightward to insert into the lock slot to complete the locking. At this time, the vehicle lock device is in the locked state. Figure 2 shown.

[0062] Example 5

[0063] This embodiment shows an implementation of a bicycle, which includes the bicycle lock device in Embodiment 4 or its equivalent. Figure 4-5 As shown, the bicycle lock device is installed on a bicycle. In this embodiment, the lock body matching piece is installed to the middle tube of the frame, and the trigger piece forms the bicycle's foot support. The bicycle in this embodiment can also be replaced by an electric power-assisted bicycle.

[0064] Figure 4 It is a schematic diagram of a bicycle in the locked state, that is, the bicycle lock device is in the locked state, at this time, the lock body fitting 1 is in the first position, the locking rod 42 is embedded in the locking groove 11, the footrest is locked and cannot be rotated counterclockwise or clockwise, so that the lock body fitting 1 cannot move between the first position and the second position.

[0065] When the user needs to use the bicycle, the bicycle receives the unlocking command, and the motor 41 of the lock body 4 drives the lock rod 42 to move in the direction of disengaging from the lock slot 11 until it disengages from the lock slot 11, thereby releasing the lock rod 42 from the restriction on the upward and downward movement of the lock body matching part 1, and then opens the foot support clockwise. At the same time, the foot support drives the outer turntable to rotate, and the outer turntable drives the lock body matching part to move downward along the middle tube of the frame to the second position, completing the unlocking. At this time, the bicycle is in an unlocked state and can be ridden by the user. Figure 5 shown.

[0066] Figure 5 It is a schematic diagram of a bicycle in unlocked state, that is, the bicycle lock device is in unlocked state, at which time the lock body fitting 1 is in the second position, the lock rod 42 is out of the lock slot 11, and the lock body fitting 1 can move between the first position and the second position.

[0067] When the user finishes riding, the user can lock the bike by returning the kickstand to the ground to park the bike, without having to perform additional locking operations. More specifically, after the user finishes riding, the user can turn the kickstand counterclockwise to return the kickstand to the ground to park the bike (e.g. Figure 4 During this process, the footrest drives the outer turntable to rotate, and the outer turntable drives the lock body matching piece to move upward along the middle tube of the frame to the first position, and then the motor of the lock body drives the lock rod to move toward the lock slot until it is embedded in the lock slot, the footrest is locked, and the lock is completed. At this time, the bicycle is in the locked state. Figure 4 shown.

[0068] The foot support in this embodiment can also be designed so that, in the locked state, the rear wheel of the bicycle or electric power-assisted bicycle does not contact the ground. For example, the length of the foot support is designed to be greater than the radius of the rear wheel.

[0069] The present invention provides a novel switch lock structure, which integrates the switch lock behavior into the use process of the bicycle, greatly simplifying the switch lock process. In particular, after the user finishes riding, the user can turn the footrest counterclockwise to return it to the ground to achieve the lock, without the existing additional lock operation.

[0070] When the lock is damaged, the internal components will not be damaged, the bicycle or electric assisted bicycle will not be lost, and the bicycle or electric assisted bicycle that has been illegally moved after being locked can be found.

[0071] When a bicycle or electric assisted bicycle is damaged, it can be put back into use by replacing the kickstand, thus reducing operation and maintenance costs.
