A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.

A charging apparatus includes at least one housing including a compartment, an access door connected to the housing and covering the compartment, the access door being movable from an open position to a closed position, a releasable latching mechanism configured to latch the access door in the closed position, a charging terminal in the compartment, a voltage sensing terminal, and a door release circuit coupled to the voltage sensing terminal and to the releasable latching mechanisms and configured to sense a charging voltage applied to the voltage sensing terminal. The door release circuit is configured to selectively unlatch the releasable latching mechanism in response to a voltage within a predetermined voltage range being applied to the voltage sensing terminal.

A locking knife holder uses either mechanical or electronic locking systems to secure the knives into the holder. The electronic locking system includes the implementation of one or more electromagnets into the holder. The user can then selectively lock or unlock the knives in the holder by activating or deactivating, respectively the electromagnet. In other implementations, the mechanical locking system can use magnetic keys to unlock the mechanical locking system.

An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.

A combination lock is provided, the lock having a latch movably mounted to a housing of the lock for movement between a locked position and an unlocked position; and a bolt movably mounted to the housing of the lock for movement between a first position and a second position, wherein the combination lock is a key-controlled combination changing permutation lock wherein a button disposed away from a rear exterior surface of the housing in a first direction rearwardly away from the rear exterior surface is depressed in order to change the combination of the combination lock and the housing has a button protection feature extending rearwardly away from the rear exterior surface of the housing in the first direction proximate to the button and the button protection feature extends farther away from the rear exterior surface of the housing in the first direction than the button.

A locking module for selectively coupling a first component and a second component of a lockable device includes a housing and a magnet arranged within said housing. A locking element is movable relative to said housing between an unlocked position and a locked position. An engagement member is rotatable about an axis to selectively decouple said locking element from said magnet to move said locking element between said unlocked position and said locked position.

A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.

An exemplary trim lock device is configured for use with a trim comprising a lift finger, and generally includes a housing, a blocking member, and a lock actuator. The blocking member includes a projection, and is rotatably mounted to the housing for rotation between a blocking position in which the projection blocks actuating movement of the lift finger and an unblocking position in which the blocking member does not block actuating movement of the lift finger. The lock actuator is operable to rotate the blocking member between the blocking position and the unblocking position.

A lock unit of an electric locking device comprises a lock housing, a keeper, an inhibitor and a latch bolt. A second end of the latch bolt is positioned outwardly and cooperates with the inhibitor when in a locked orientation. The keeper includes a keeper shaft having a shaft axis of rotation, wherein said keeper is rotatable about said keeper shaft between first and second rotational positions, wherein the keeper is movable between first and second directional positions relative to the lock housing, wherein the movement between the first and second directional positions is generally linear, wherein when the keeper is held in the first rotational position and the first directional position by the inhibitor, the door is secured to the door frame, and wherein when the keeper is in the second rotational position and the second directional position, the door is allowed to move away from said door frame.

A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.
