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.

A battery cell (9) extends in the housing interior (64) and is in partially surrounding relation of the motor (10). The battery cell is in operative electrical connection with the motor (10). In cross section, the battery cell (9) includes at least two points (34) and (36) such that a line segment (32) joining these two points passes through the motor (10).

Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

The present invention relates to an electronic lock. The electronic lock includes a turn piece coupled with a cylinder connecting spindle; an electric motor connected with a first bevel gear; and a dislocation transmission mechanism including a first dislocation member coupled with the turn piece and the cylinder connecting spindle and having an arc opening, and a second dislocation member engaged with the first bevel gear and having a protrusion, in which the protrusion is configured to extend into the arc opening, such that when the protrusion is engaged with either a first engaging portion or a second engaging portion at two ends of the arc opening, the first dislocation member is driven by the second dislocation member, and when the first dislocation member is in motion within a void range defined by the arc opening, the first dislocation member fails to drive the second dislocation member.

A dead bolt lock system including a slider member operatively coupled to a dead bolt such that when the slider member is in a first position, the dead bolt is in an extended position. When the slider member is in a second position, the dead bolt is in the retracted position. The system also includes a first movable member positioned in a path of movement of the slider member and configured to be displaced by the slider member to allow the slider member to move to the second position. The system includes a first lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member, a second lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member.

A domestic electrical appliance, in particular a dishwashing machine, includes a main appliance body having a product treatment chamber, a door mounted on the main appliance body so as to be pivotable about a horizontal pivot axis close to the floor for closing an access opening to the product treatment chamber and a locking device having a locking assembly arranged on the main appliance body and a closing pin arranged on the door. The locking assembly has a latch movable between a release position and a latching position where the latch engages behind the closing pin to hold the door closed and releases the closing pin to open the door. The latch performs a rotational movement along a horizontal plane as it moves between the release position and the latching position, the closing pin being oriented vertically when the door is closed.

Disclosed is a household appliance comprising: a door; a door lock unit equipped with a hook part which is configured to unlock and open the door by moving outward; a motor configured to generate torque by using electricity; a driving gear unit which has a rotary shaft at one end portion and is configured to rotate by receiving the torque from the motor, wherein the one end portion pushes the hook unit to the outside of the door lock unit to open the door when the driving gear unit rotates in one direction; a sensing unit configured to sense the displacement of the other end portion of the driving gear unit when the hook unit moves to the inside of the door lock unit, wherein the other end portion rotates in the opposite direction about the rotary shaft of the driving gear unit; and a control unit configured to control the operation of the motor on the basis of the displacement, sensed by the sensing unit, of the other end of the driving gear unit.

An electronic lock includes a deadbolt, a driver mechanism, a transmission mechanism and a control mechanism. The transmission mechanism includes a transmission gear that is driven by the driver mechanism to rotate, a resilient unit that is mounted to and co-rotatable with the transmission gear, and a rotary member that is operable to rotate relative to the transmission gear between a locking position and an unlocking position, and that is connected to the deadbolt. The control mechanism is connected to the rotary member, and ceases operation of the driver mechanism when detecting that the rotary member has been rotated to one of the locking and unlocking positions.

An exemplary method includes operating an access control device including a bolt, an output gear having a magnet mounted thereon, a first magnetic sensor, and a second magnetic sensor. The method generally includes selectively determining a position of the output gear via one of the first magnetic sensor or the second magnetic sensor based upon a current handedness of the access control device. With the access control device in a first handing configuration, the first magnetic sensor may be used to a first handedness first home position of the output gear. With the access control device in a second handing configuration, the second magnetic sensor may be utilized to detect a second handedness first home position of the output gear

An intelligent lock mechanism includes a retrofittable apparatus comprising a constant temperature monitor, wherein the lock apparatus can be maintained at an operating temperature by engaging the motor to keep sufficient temperature for consistent operability.
