Meanwhile, two bushings 8 are distributed on both sides of the main gear 7 to restrict the main gear 7 from moving in the axial direction.

Example two

Referring to fig. 6 to 8, the difference between the present embodiment and the first embodiment is: the duplicate gear 6 is provided with three duplicate gears a meshed with the second bevel gear 5 in sequence, a duplicate gear c meshed with the main gear 7 and a duplicate gear b meshed between the duplicate gear a and the duplicate gear c, the motor 3 drives the first bevel gear 4 to rotate, and the motor sequentially transmits the second bevel gear 5, the duplicate gear a, the duplicate gear b and the duplicate gear c to the main gear 7 to drive the main gear 7 to rotate, and the embodiment obtains a larger reduction ratio by arranging the three duplicate gears 6. A groove is formed in a side surface of the duplicate gear b facing the bottom case of the housing 10, and a permanent magnet 11, specifically a magnet, is fixed in the groove. The bottom shell of the housing 10 is provided with a hall sensing element 12 on the outer side wall, and the hall sensing element 12 is located at the opposite position of the rotating path of the permanent magnet 11. When the duplicate gear b drives the permanent magnet 11 to rotate and pass through the hall detection element 12, the hall detection element 12 can generate a pulse signal. Further, the hall detection element 12 is electrically connected to a circuit control module in the automatic lock, and is configured to send a pulse signal to the circuit control module, and the circuit control module controls the motor 3 to stop rotating according to the received pulse signal.

The working process of the embodiment is as follows: when the automatic lock is started for the first time, the automatic lock is controlled by the circuit control module to enter a self-learning mode, the motor 3 drives the rotating shaft 2 to link the lock body through the gear set until the motor 3 is in a locked state, and locking is completed; then the motor 3 rotates reversely, the rotating shaft 2 is driven through the gear set to be linked with the lock body until the motor 3 is in a locked-rotor state, and unlocking is completed. In the action process of the motor 3 from the locked rotor state to the unlocked locked rotor state, the Hall detection element 12 is triggered once through the permanent magnet 11 every time the duplicate gear b is driven to rotate for one circle, the Hall detection element 12 generates a pulse signal to the circuit control module, after the locking and unlocking actions are completed, the number of rotation turns a of the duplicate gear b is obtained through accumulation, the number of rotation turns b needed from the unlocking or locking to the central position is determined, namely the number of rotation turns b is half of the number of rotation turns a, the number of rotation turns b is used as a threshold value, and self-learning is completed. When locking or unlocking, after the circuit control module detects that the number of rotation turns of the motor 3 driving the duplicate gear b reaches the number of rotation turns b (namely locking or unlocking is completed) through the hall detection element 12, the control motor 3 stops, and then reverses to reset the handle 1 to the central position.

Compare with embodiment one, this embodiment detects duplicate gear 6's rotatory number of turns through adopting hall detecting element 12 and controls motor 3 to reach the action of locking and unblanking of accurate control automatic lock, and motor 3 need not the stall during subsequent use, can effectively reduce the energy consumption, and the standby time of extension automatic lock avoids the user to frequently charge.
