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.

Described herein is a lock actuation assembly for actuating a state change of a lock of a door via a lock actuator extending from a panel of the door, comprising: a motor for driving the actuation; a body having a mounting portion for attaching the lock actuation assembly to the door; a coupler held by the body for coupling a force from the motor to the lock actuator to change the lock's state; a wireless communication module for receiving in, an electromagnetic signal, a first command for changing the state of the lock; a turnable piece on the body for generating a second command for changing the state of the lock; and a controller adapted to control the motor to change the state of the lock based on either one of the first command or the second command.

Provided is a locking/unlocking device that accurately detects an opening/closing state of an opening/closing device and optimizes timing to lock or unlock.

The locking/unlocking device includes a drive unit that drives a lock mechanism of the opening/closing device, a magnetic detection unit that detects a change in a magnetic field based on a change in the relative position between a movable section and a fixed section of the opening/closing device, and a control unit that determines an open/closed state of the opening/closing device on the basis of the change in the magnetic field detected by the magnetic detection unit and activates the drive unit to lock or unlock the lock mechanism on the basis of the open/closed state.

An intelligent door lock system coupled to a door at a dwelling. a door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

This invention describes an electric drive mechanism (120) for translating a blocking member (126) to secure or release a lock. The lock is configured as a latch lock (100), a slide bolt padlock (200), a U-shackle padlock (300) or a snap padlock (400). The blocking member (126) is supported by two or more steel balls (130) disposed in helical grooves formed on a helical member (124) to provide a self-centering and low friction drive mechanism (120), which allows an electric motor (122) connected to the helical member to be small and of low power. Unobstructed movement of the blocking member (126) is provided by an alignment or detent mechanism (160, 217, 317) or torsion spring in the snap padlock (400). An electronic control board (140) allows electronic operation of the lock via an application in a smartphone. A PCB (121) located near the electric motor provides tamper-proofing.

A lock module comprises a cylinder including a control latch configured to mechanically rotate between an extended position to prevent removal of the cylinder from a lock assembly, and a retracted position to allow removal of the cylinder from the lock assembly. A rotator is configured to enable the control latch to rotate between a locked position and an unlocked position. An actuation rod is configured to travel between a tab-blocking position maintaining the control latch in the extended position, and a retracted position allowing the control latch to retract into a retracted position. A control pin is configured to restrict the travel of the actuation rod in a control pin-blocking position in response to the rotator being rotated to a locked position and to retract from blocking the travel of the actuation rod to the control pin-unblocking position in response to the rotator being rotated to an unlocked position.

A door lock actuation device configured for operating a door lock in a door blade, wherein the door lock includes a dead bolt driven by rotation of a connector is provided. The device includes a casing, inside which there is provided a motor for driving a rotational connector-receiver that receives and rotates the connector. The device also includes a rotational handle mechanically connected to the connector-receiver, for forcing rotation of the connector-receiver by manual rotation of the handle. The motor is selectively disconnectable from the connector-receiver for manual driving of the connector-receiver by the handle without backdriving the motor.

An intelligent door lock system is coupled to a door at a dwelling. A first sensor is at the dwelling. The first sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. The lock device is coupled to the first sensor and the lock device includes a bolt. An engine, an energy source and a memory are coupled together. A magnetic sensor provides a reading or measurement used to determine a door open or closed status.

The present application provides an electric lock device, adopting a clutch mechanism composed of a driven gear and a turntable. The first side of the driven gear is provided with a mounting position for the turntable to be embedded, the sidewall of the mounting position is provided with an arc-shaped recess, and the outer sidewall of the turntable is provided with an arc-shaped bump corresponding to the arc-shaped recess. The central angle corresponding to the arc-shaped recess is denoted as α, and the central angle corresponding to the arc-shaped bump is denoted as β, then α and β satisfy: α−β≥180°. Based on the above structure, there is a rotation virtual position greater than or equal to 180° between the driven gear and the turntable, that is, the gear can be rotated at least 180° regardless of the angle to which the gear rotates the turntable.

An exemplary Internet of Things (IoT) module for a lockset includes a housing assembly configured for mounting with the lockset, a controller, a wireless transceiver, and a sensor array, and may further include an LED array. The controller is in communication with an external device via the wireless transceiver, and is configured to transmit to the external device information received from the sensor array. The controller is further configured to control operation of the LED array based on information received from at least one of the sensor array or the external device.
