Patent ID: 11905737

Abstract:
An exemplary embodiment provides an electric lock, comprising: (a) a knob; (b) a lock body; (c) a rotatable shaft comprising a rotatable-shaft front end and an opposing rotatable-shaft rear end, wherein the rotatable-shaft rear end is fixedly connected to the lock body to control a locking and unlocking of the lock body; (d) a gear assembly comprising a gear and a movable piece with a common axis center; and (e) a motor assembly for driving the gear to rotate. The knob and the rotatable shaft are connected via the movable piece; the movable piece interacts with the gear via a mechanical barrier, such that electrically driving the gear by the motor assembly causes the movable piece to rotate; and the movable piece can pass over the mechanical barrier when a sufficient rotational force is applied to the knob, such that the movable piece is free to rotate relative to the gear, thereby allowing a user to manually control the locking and unlocking of the lock body. In some exemplary embodiments, the provided design of the electric lock structure significantly improves the safety of the electric lock.
