An intelligent unlocking device comprises a rear shell, a front shell, a motor assembly, a hollow rotating shaft, an adapting piece connected with a lock cylinder and the hollow rotating shaft, a manual rotating shaft, an inner bearing and a bearing support which are disposed around the manual rotating shaft, and an outer bearing. The bearing support and the outer bearing are disposed around an end of the manual rotating shaft. The intelligent unlocking device is silent and free of noises in use, and convenient to assemble and disassemble, intelligent unlocking can be achieved without replacement of a whole door lock, and costs are reduced for users.

A merchandise security device is provided. The merchandise security device may include a lock mechanism operably engaged with a shape memory material configured to receive electrical power for locking and unlocking the lock mechanism. The shape memory material may be configured to change in shape in response to receiving electrical power to thereby lock or unlock the lock mechanism.

In some embodiments, a method of determining whether a door is ajar may include determining an orientation of a door lock of the door, and, based on the orientation of the door lock, analyzing at least one signal from at least one of two or more proximity sensors of the door lock. The method may further include determining whether the door is ajar based at least in part on a result of the analyzing of the at least one signal. In some embodiments, a method of determining a status of a door may include receiving a first signal from a first magnetometer disposed within a door lock of the door, receiving a second signal from a second magnetometer disposed within the door lock of the door, and detecting, based on a result of an evaluation of both the first signal and the second signal, a possible attack on the door.

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.

The present invention provides a motorised door lock assembly 10 in order for a user to be able to lock and unlock a door remotely and/or with a conventional key or with a thumb turn 22 from the inside. In particular, a user may decide to continue to use a key from the outside and the thumb turn (or an internal key mechanism) from the inside but at any stage the user (or a different user) may decide to operate the lock remotely. The motorised system may be activated by a number of actuators and, in particular, the motorised system may be activated by a remote key fob, a smart phone, an internally mounted push button or an external key pad. The assembly of the present invention is able to provide a continuous choice of all three methods (where permitted) without the risk of the lock becoming stuck in one position and without the user having to perform an elaborate particular sequence to operate the lock. The present invention is particularly for use with a Euro cylinder lock combined with a multipoint locking system 14 which thereby has operating limitations. The remotely activated motorised mechanism comprises a motor 50, a worm gear 52, a driven gear 54, rotary locking spindle engagement means 30 to transmit movement of the motor 50 to a rotary locking spindle of the cylinder lock, and a remote control actuator, the remotely activated motorised mechanism further comprising a multipoint monitoring system to determine an operational status of the multipoint locking mechanism and a rotary lock bolt monitoring system to determine an operational status of the lock bolt; and wherein the rotary locking spindle engagement means is arranged to directly engage a component of a thumb turn mechanism of a door lock.

A door lock that includes a clutch mechanically arranged between a drive motor and a lock drive with the clutch having a clutch gear that is movable between engaged and disengaged positions to selectively couple and uncouple the drive motor from the lock drive from the drive motor. The clutch gear may be movable along a pathway between engaged and disengaged positions, e.g., in a direction perpendicular to a rotation axis of the clutch gear. The clutch gear may selectively couple and uncouple the drive motor from the lock drive based on movement of the drive motor.

A door lock includes a motor and thumb turn that can be selectively used to move a lock drive and lock mechanism between lock and unlock positions. A position sensor can detect a position of the lock drive independent of movement of any drive train component operating to move the lock drive, such as a motor, transmission or other drive train element. The position sensor may be coupled to a position gear that moves in response to lock drive movement, but is independent of any drive train component, i.e., the position gear does not transmit drive energy to the lock drive. A clutch may be provided that decouples the drive train from the lock drive.

A merchandise security device is provided. The merchandise security device may include a lock mechanism operably engaged with a shape memory material configured to receive electrical power for locking and unlocking the lock mechanism. The shape memory material may be configured to change in shape in response to receiving electrical power to thereby lock or unlock the lock mechanism.

An intelligent unlocking device comprises a rear shell, a front shell, a motor assembly, a hollow rotating shaft, an adapting piece connected with a lock cylinder and the hollow rotating shaft, a manual rotating shaft, an inner bearing and a bearing support which are disposed around the manual rotating shaft, and an outer bearing. The bearing support and the outer bearing are disposed around an end of the manual rotating shaft. The intelligent unlocking device is silent and free of noises in use, and convenient to assemble and disassemble, intelligent unlocking can be achieved without replacement of a whole door lock, and costs are reduced for users.

A key, a lock core and a lock, relating to a key, a lock core and a lock are provided. The key includes: a column body, a first end of the column body being provided with a light emitting component; a first cathode component disposed on the column body and connected to one end of the light emitting component to be mated with a second cathode component in the lock core; a first piezoelectric electrode disposed on the column body and connected to the other end of the light emitting component to be pressed against a second piezoelectric electrode in the lock core. When the first cathode component is mated with the second cathode component in the lock core, and the first piezoelectric electrode is pressed against the second piezoelectric electrode in the lock core, a piezoelectric current is generated, to cause the light emitting component to emit light.
