Whether it is used for anti-theft or parking, the tire locking device is an important structure that greatly affects the safety and user experience of the vehicle. When the tire locking device is applied to an electric bicycle, in order to ensure safety and easy control, when the vehicle stops moving after power failure, the tire locking device needs to lock the tire to ensure that the vehicle stops and cannot move.

[0003] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0025] like Figure 1-4 As shown, the present invention proposes a tire locking device for installation on a bicycle, comprising a locking flange 101, the locking flange 101 being fixed to a turntable 102 of the bicycle. A lock box 103, the lock box 103 being arranged on the frame of the bicycle, the lock box 103 comprising a housing 1031, a locking pin 1032 capable of extending and retracting on a vertical plane of the turntable 102, and an intermittent motion mechanism 1033 for driving the locking pin 1032, the housing 1031 being provided with at least one through hole 1034, the locking pin 1032 extending from the through hole 1034. The locking flange 101 is provided with a plurality of locking grooves 1011, the locking grooves 1011 being provided with slopes 1012 on both sides. A rounded corner or chamfer is provided at one end of the locking pin 1032 facing the locking groove 1011. The purpose of setting the slope 1012 and the chamfer or rounded corner is to allow the locking pin 1032 to automatically pop open during high-speed operation, and to be successfully locked only when the driving motor Q is stationary and slowly rotating, so as to better ensure the safety during riding.

[0026] In one embodiment, the intermittent motion mechanism 1033 is a cam mechanism, and the locking pin 1032 is abutted against the cam of the cam mechanism to achieve extension and retraction. At the same time, a micro motor 1035 is also required in the lock box 103 to serve as a power source for the intermittent motion mechanism 1033, so as to continuously push the locking pin 1032 toward the locking groove 1011.

[0027] In one embodiment, the diameter of the through hole 1034 is greater than the diameter of the locking pin 1032, and the locking pin 1032 has at least radial freedom relative to the through hole 1034. Specifically, when the driving motor Q does not stop running, the turntable 102 and the locking flange 101 both maintain high-speed motion, and at this time, when the locking pin 1032 extends into the locking groove 1011, it will be bounced open. In order to protect the locking pin 1031 and the locking flange 101 from being damaged by high-speed impact, the characteristics of the intermittent motion mechanism 1033 are utilized, so that the locking pin 1032 can quickly break away from the contact with the locking flange 101 to prevent damage. Furthermore, when the locking pin 1032 is hit by the locking groove 1011, the locking pin 1032 will be subjected to the radial moment of the through hole 1034. When the locking pin 1032 is respectively connected to at least the first elastic member and the second elastic member in the transverse and longitudinal directions, the first elastic member is used to restore the locking pin 1032 to a position away from the locking flange 101, and the second elastic member is used to restore the angle of the locking pin 1032 after being hit by the locking flange 101, thereby realizing the radial freedom of the locking pin 1032.

[0028] In order to prevent the locking flange 101 locked by the locking pin 1032 in the static state from escaping easily, the elastic range of the second elastic member must be smaller than the width of the slope to prevent the situation where the locking cannot be performed normally. The first elastic member and the second elastic member can be made of springs or other elastic materials.

[0029] On the other hand, the present invention also proposes an electric bicycle, comprising any of the tire locking devices described above, wherein the driving motor Q of the electric bicycle is a hub motor or a mid-mounted motor, wherein the tire locking device has a wireless signal transceiver to facilitate the user to control the locking of the bicycle.

[0030] In summary, there is a simple harmonic motion mechanism inside the device that can drive the lock pin toward the lock slot of the locking flange. When a locking signal is detected, the lock pin will pop out and get stuck in the locking flange slot. When the motor is detected to be running at high speed during locking, the lock pin will be popped out of the locking slot and cannot be locked. The locking slot and the lock pin are both provided with chamfered angles to automatically pop open the lock pin when running at high speed. The lock can only be successfully locked when the motor is stationary or rotating slowly. The setting of this solution can ensure safety during riding.

[0031] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
