An electronic lock cylinder contains: a receiving sleeve, a lock head, a fastener, a rotation element, a rotatable actuation element, a driven element, a drive motor, a resilient element, an operation element, a locking element, and a locating cap. Thereby, the drive motor moves clockwise or counterclockwise to drive the rotary column to rotate 90 degrees and to simultaneously actuate the driven element, the drive motor, the resilient element, and the engagement projection of the operation element to move forward or backward to rotate or rotate idly in the notch of the locking element, thus saving energy and obtaining environmental protection.

An electric lock includes a housing, a manual control member rotatably affixed to the housing, and a clutch mechanism. The clutch mechanism includes a clutch base rotatably affixed to the housing; a retractable plug arranged on the clutch base, wherein the retractable plug is radially movable relative to the clutch base; a driving member abutting against a first end of the retractable plug; and a motor configured to drive the driving member to move relative to the clutch base toward the shaft of the manual control member.

A redundant actuation lock apparatus includes an interface, an electronic mechanism, and a manual mechanism. The interface manipulates lock bar(s) into a locked/unlocked position. The electronic mechanism includes an actuator and power drive. The actuator is disengageably coupled to and drives the interface. The power drive is coupled to and drives the actuator in response to a control signal. The manual mechanism includes a key input and an output. The key input receives and rotates with a mechanical key. The output disengageably couples to the interface and rotates with the mechanical key. The actuator is engaged with and the output is disengaged from the interface in an electronic mode, while the actuator is disengaged from and the output is engaged with the interface in a manual mode.

A locking module (40) for selectively coupling a first component and a second component of a lockable device (20) includes a locking member (42) rotatable between an unlocked position and a locked position and an engagement member (50) associated with said locking member (42). Translation of said engagement member (50) drives movement of said locking member (42) between said locked position and said unlocked position to selectively decouple said first component from the second component.

A clutch includes an outer box and an intermediate member pivotably connected to the outer box. The intermediate member is coupled with an outer handle to pivot therewith. A torsion spring is disposed between the intermediate member and the outer box and biases the intermediate member to an initial position. A coupling member is pivotably mounted between the intermediate member and the outer box and is operatively connected to a first latch of a latch device of a lock device. When the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position. When the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch. A lock device with the clutch is also disclosed.

Disclosed is a lever-type door lock driving assembly which can be installed inside a mounting hole to enable miniaturization of the device, ensure general versatility, and prevent a fragile area from being generated inside the door. The present invention relates to a driving assembly for a lever-type door lock arranged in an installation hole to drive a latch operating body, wherein the mounting assembly comprise a mounting module having a truncated disc shape and having at least one driving plate therein; and a motor unit mounted on the truncated area of the mounting module and having a disk shape in a state of being coupled to the mounting module.

An electric lock includes a housing, a clutch mechanism and a manual control member. The housing is formed with a driving structure having a first inclined surface, a second inclined surface and a bottom surface. The clutch mechanism includes a driving member having a pushing structure, an elastic member arranged on the driving member for abutting against the driving structure, a rotating member having a pushed structure, and a motor for driving the driving member to rotate. The manual control member is connected to the rotating member. When the motor drives the driving member to rotate relative to the driving structure, the elastic member abuts against the first or second inclined surface to push the driving member to move toward the rotating member, so as to allow the pushing structure to abut against the pushed structure, in order to further drive the rotating member to rotate the manual control member.

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.

An inline motorized lock drive is mountable within a lock housing to drive a sliding locking element between a locked and unlocked position. The lock drive includes a reversible motor having a shaft with an auger thereon to drive a lock spring, which drives the locking element. The sliding motion of the locking element is axially aligned with the motor axis to substantially reduce friction. The lock drive is preferably modular and emulates a solenoid lock drive with a control circuit. The control circuit is connected to drive the motor is switchable to default to a locked position or an unlocked position and emulate a “fail safe” or a “fail secure” type solenoid lock drive. The control circuit operates on 12 or 24 volts to replace solenoid locks of either voltage and stores power when power is applied, then uses the stored power to return the lock drive to the selected default state when power is removed.

An arrangement (10) for a lock device (88a, 88b), the arrangement (10) comprising an input member (12, 106); a coupling member (26) movable between an uncoupled position (34) and a coupled position (80); an electromechanical actuator (28) comprising an actuating member (42) linearly movable between an uncoupling actuating position (44) and a coupling actuating position (78); and a torsion spring (30) having a first leg (62) and a second leg (64) movable away from each other against a deformation of the torsion spring (30), wherein the actuating member (42) is arranged to engage the first leg (62) and the second leg (64) is arranged to engage the coupling member (26) when the coupling member (26) is in the uncoupled position (34) and the actuating member (42) moves from the uncoupling actuating position (44) to the coupling actuating position (78). A lock device (88a, 88b) comprising an arrangement (10) is also provided.
