It should be noted that, in the embodiment of the present application, the first spring 47 is a rectangular spring, which has a larger elastic force and a better anti-fatigue effect.

In the embodiment of the present application, the intelligent vehicle lock further has a control chip inside for controlling the movement of the driving motor 41, and the driving chip is installed in the installation housing 223. When the shared bicycle needs to lock the bicycle in the process of high-speed movement, the control chip can control the output shaft of the driving motor 41 to rotate slowly, so that the expansion brake 3 locks the hub slowly, and safety accidents caused by locking of the hub in the driving process are prevented. After the shared bicycle is parked, the user can send a bicycle locking instruction through the mobile intelligent terminal to enable the control chip to control the driving motor 41 to rotate faster than the output shaft, so that the bicycle locking of the shared bicycle is realized, and the bicycle locking time is short.

The implementation principle of the intelligent bicycle lock for sharing the bicycle in the embodiment of the application is as follows: the hub is braked by the expansion brake 3, so that the hub is gradually decelerated and braked in the rotating process; and a driving component 4 is arranged, the driving motor 41 drives the sliding block 42 to slide so as to drive the expansion brake 3 to be pressed against the hub, and therefore the gradual deceleration braking of the hub is realized through the friction force generated between the expansion brake 3 and the hub. And after the driving assembly 4 is reset, the expansion brake 3 can be manually controlled by a user to brake during running.

The embodiments of the present invention are preferred embodiments of the present application, and the protection scope of the present application is not limited thereby, wherein like parts are denoted by like reference numerals. Therefore, the method comprises the following steps: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
