when an unlocking signal is obtained, the motor 5 is rotated to drive the clamping shaft 1 to slide in a direction away from the lock cylinder sleeve 4 through the eccentric boss, and when the interference part 111 on the clamping shaft 1 is separated from the lock cylinder sleeve 4, the motor 5 stops rotating;
when the displacement of the magnet 10 on the lock cylinder sleeve 4 exceeds a preset distance, the PCBA cannot sense the magnet 10 on the lock cylinder sleeve 4, and the motor 5 is controlled to rotate reversely, so that the eccentric boss drives the clamping shaft 1 to move towards the direction close to the lock cylinder sleeve 4.
Compared with the prior art, the lock control method has the same advantages with the lock, and the detailed description is omitted.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the disclosure, and these changes and modifications are intended to fall within the scope of the invention.
