[0049] The wheel movement detection device 8 can also be equipped with GPS+Beidou, central lock voltage detection, voice function, remote control function, and Bluetooth function, which can realize high-precision fixed-point return of the vehicle as required.

[0050] The present invention implements the unlocking process: the central control system or controller issues an unlocking command, the driving circuit board 802 receives the command and causes the motor 601 to reverse and drive the gear linkage mechanism 6 so that the locking pin 704 of the driving mechanism 7 disengages from the lock slot 402, the switch triggering boss 805 disengages from the trigger point of the signal switch 804, the locking signal changes, the driving circuit board 802 reports the unlocking completion to the central control system or controller and enters the sleep state, and voice prompts "the vehicle has been unlocked", and the consumer can use the vehicle normally.

[0051] The present invention implements the locking process: the central control system or controller issues a locking command, the driving circuit board 802 receives the command and drives the motor 601 to rotate forward to drive the gear linkage mechanism 6 so that the lock pin 704 of the driving mechanism 7 is inserted into the lock slot 402. At this time, the wheel Hall 803 detects whether the brake disc 4 is rotating:

[0052] (1) If the brake disc 4 rotates, the Hall signal changes when the magnet 404 passes through the wheel Hall 803, indicating that the brake disc 4 is rotating and the consumer is using it, which is a system error. At this time, the driver circuit board 802 does not execute the lock command and gives a voice prompt "Do not lock the bike while riding";

[0053] (2) If the brake disc 4 does not rotate and the wheel Hall 803 detection signal does not change, it means that the vehicle is stationary and the consumer is locking the vehicle normally. The driver circuit board 802 executes the instruction to make the motor 601 rotate forward to drive the gear linkage mechanism 6 so that the lock pin 704 of the drive mechanism 7 is inserted into the lock slot 402. At the same time, the switch triggering boss 805 on the rack 701 approaches the position of the signal switch 804. The locking signal feedback is realized through the triggering of the signal switch 804 and the switch triggering boss 805. The driver circuit board 802 reports to the central control system or controller that the locking is completed and enters the sleep state, and gives a voice prompt "The vehicle is returned successfully".

[0054] Standardize parking implementation process:

[0055] (1) The consumer sends a request to return the car to the sharing platform through the mobile phone APP, and the sharing platform sends a return command to the central locking system. The GPS and Beidou positioning of the driver circuit board 802 detect that the car is not within the electronic fence or the designated return point, and sends an "illegal parking" signal to the sharing platform, does not execute the lock command, and gives a voice prompt "Please park at the return point in a standardized manner";

[0056] (2) The consumer sends a request to return the car to the sharing platform through the mobile phone APP, and the sharing platform sends a return instruction to the central lock. The GPS and Beidou positioning of the driving circuit board 802 determine that the car is within the electronic fence or the designated return point, and the driving circuit board 802 executes the aforementioned locking process.

[0057] Therefore, the lock can be remotely operated by the sharing platform, and can communicate with the central control lock in real time. The switch status of the lock and the rotation status of the rear wheel can be monitored. GPS and Beidou provide reliable hardware support for electronic fence technology, which provides technical support for governments and enterprises to solve the problem of shared bicycles being parked randomly and enables consumers to park in a standardized manner, which is more in line with the operation mode of smart products.

[0058] The above contents are examples and explanations of the present invention, but do not mean that the advantages that can be achieved by the present invention are limited thereto. Any simple changes in the structure that may be made during the practice of the present invention, and / or one or more of the advantages achieved in some embodiments are within the scope of protection of this application.
