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 lock device adapted for a first object and a second object movable relative to the first object includes a slider, a driving module, a latch and a power module. The driving module can drive the slider to move between a locking position and an unlocking position. The latch is movable relative to the slider. The power module can provide electricity to the driving module. When the second object is located at a retracted position relative to the first object, the driving module can drive the slider to move to the locking position, so that the latch blocks the second object. When the driving module is not driven by the power module, the latch is driven by the second object moving in an opening direction to move from an original state to a non-original state for driving the slider to move from the locking position to the unlocking position.

A motor vehicle lock including a catch, a pawl, and a drivetrain arrangement with a drive element. When the catch is in the secondary closed position, the pawl is moveable from the engaged state the released state to release the catch. The drive element may be configured to move in a predefined drive direction. The motor vehicle lock may include a first coupling element, provided with a first coupling surface and a second coupling element, provided with a second coupling surface. During the cinching sequence, the first coupling surface and the second coupling surface may be engaged with one another to move the catch. During the release sequence the drive element is moved in the predefined drive direction such that the first coupling surface and the second coupling surface are disengaged from one another.

An electric lock with electric and manual unlock mode, comprising: a case combining with a side plate and a case cover; a latch bolt, a latch bolt shaft and a latch bolt spring, the front end of the latch bolt shaft is combined with a blocking member, and the blocking member uses the elastic force of the latch bolt spring to stick out of the side plate to lock, when the external force applied to the latch bolt shaft is sufficient to resist the elastic force of the latch bolt spring, the blocking member will retract into the side plate to unlock; a unlock crank, having an electric push member and a manual push member, and a push member relative to the latch bolt shaft; and a linear actuator and an actuating arm, the outer end of the actuating arm is combined with a push block relative to the electric push member, and a push block return spring is set relative to the push block.

A lock for a closure element of a real estate property, includes a pivoting catch on which a spring acts in a preferred direction, a locking member, and a manual or mechanical drive device. The locking member is designed as a rotary locking member that is driven by the drive device in a circulating manner about a locking member axis in only one rotational direction and comprises multiple locking elements which are offset to one another over the angle at the circumference of the locking member and which interact with the pivoting catch as respective tumblers depending on the rotational angle. Only one of the locking elements constantly acts directly on the pivoting catch for a locking and unlocking process, and the adjacent locking element opposite the rotational direction of the rotary locking member acts on the pivoting catch by rotating the rotary locking member for a subsequent locking and unlocking process.

A door locking system includes a door movably mounted on a rail. The door includes rollers rollably coupling the door to the rail. An opener is coupled to the door. The opener positions the door in an open position and a closed position. A lock is coupled to the rail. The lock is in communication with the opener. The lock is automatically positioned in a locked position after the opener positions the door in a closed position. Thus, the door is retained in the closed position.

A lock device adapted for a first object and a second object movable relative to the first object includes a slider, a driving module, a latch and a power module. The driving module can drive the slider to move between a locking position and an unlocking position. The latch is movable relative to the slider. The power module can provide electricity to the driving module. When the second object is located at a retracted position relative to the first object, the driving module can drive the slider to move to the locking position, so that the latch blocks the second object. When the driving module is not driven by the power module, the latch is driven by the second object moving in an opening direction to move from an original state to a non-original state for driving the slider to move from the locking position to the unlocking position.

An electronic lock includes a control circuit module and an electromagnetic mechanism. The electromagnetic mechanism is electrically connected to the control circuit module, and the electromagnetic mechanism includes a driving member and a magnet. The driving member is configured to be driven by the control circuit module to be located at one of a first position and a second position. When the driving member is not driven by the control circuit module, the driving member is configured to be held at one of the first position and the second position by the magnet.
