The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1 to 7, an embodiment of an intelligent switch electronic lock includes a lock body 1, a PCB control board assembly 2 disposed on the lock body 1, and a switch lock structure assembly 3 engaged with the PCB control board assembly 2.

The lock body 1 is a main body structure body of the intelligent lock and is used for installing the PCB control panel component 2 and the switch lock structure component 3. A PCB control panel component mounting position 11, a motor mounting position 12, a large bearing mounting position 13 matched with the motor mounting position 12, a small bearing mounting position 14 matched with the large bearing mounting position 13 and a steel ball mounting position 15 are arranged inside the lock body 1.

The lock closing inductive switch 21 plays a role in sensing the in-place locking, and only when the lock closing inductive switch 21 is sensed, the cam of the switch lock structural component 3 is already rotated to the lock closing position, and the lock is successfully closed; the lock pin in-place sensing switch 22 plays a role in sensing the lock pin in-place, and the lock closing instruction can be started only when the lock pin in-place sensing switch 22 is sensed; the unlocking inductive switch 23 plays a role in sensing the unlocking position, and only when the unlocking inductive switch 23 is sensed, the cam can be indicated to be rotated to the unlocking position, and the lock is successfully unlocked.

The switch lock assembly 3 includes a motor 31, a rotating shaft 32 connected to the motor 31, a large bearing 33 sleeved on one end of the rotating shaft 32, a small bearing 34 sleeved on the other end of the rotating shaft 32, a cam 35 sleeved on the rotating shaft 32, and a steel ball 36 in contact with the cam 35, wherein a switch moving pin 37 is disposed on the rotating shaft 32. The rotating shaft 32 is connected with the lock body 1 through a large bearing 33 and a small bearing 34, so that the motor 31 drives the rotating shaft 32 to rotate, and the motor 31 provides power for rotating the cam 34. The motor 31 is arranged at the motor mounting position 12 of the lock body 1, the large bearing 33 is arranged at the large bearing mounting position 13, the small bearing 34 is arranged at the small bearing mounting position 14, and the steel ball 36 is arranged at the steel ball mounting position 15.
