Background

At present, the existing intelligent lock and electronic lock are structurally characterized in that a motor, a screw, a cam, a spring and the like are arranged on a lock body. This structure works as follows. When the door lock receives the signal, the motor in the lock body starts to rotate. At the moment, the circular motion of the motor is converted into the linear motion of the screw rod by matching with the screw rod, and then the thin rod is ejected out by utilizing the linear motion of the screw rod. And finally, the square hole of the lock body is clamped through the pushed-out thin rod, so that the square hole and the lock cylinder are kept relatively static. When the handle is rotated, the square hole is rotated through the square column, so that the lock cylinder can be rotated together, and the purpose of opening the door is achieved.

The structure of the intelligent lock and the electronic lock realizes electromechanical integration, and can better trigger the mechanical part of the lock body to work through an external electric signal, thereby achieving the purpose of electronic control of the door lock.
