A door lock includes a first driven wheel connected drivenly to a motor and having two resilient driving elements, and a second driven wheel connected drivenly to a rotary handle and the first driven wheel. The second driven wheel has a driven element disposed between and driven by the driving elements so that the second driven wheel moves to a first or second position to place a latch bolt in a latching or unlatching position. When the latch bolt is jammed, the second driven wheel is inoperative. However, as the driving elements are resilient, the first driven wheel can continue its rotation without being obstructed.

An electric door lock includes a door latch mechanism movable between latching and unlatching positions, a manual operation mechanism, and first and second rotatable members.

The first rotatable member is rotatable about an axis, and includes a rotary body and a clutch mechanism. The clutch mechanism is disposed resiliently on the rotary body and is movable parallel to the axis toward and away from the rotary body. The second rotatable member is coupled to the manual operation mechanism for co-rotation therewith, and has one side that confronts the first rotatable member and that is provided with a pushed unit.

An electric door lock including: a lock housing; an operating member having a holding part and a shaft part, the shaft part able to be placed in the lock housing, the shaft part connected to the holding part, the holding part defined as a long axis; a cog wheel able to be placed in the lock housing, the cog wheel having at least one bump; a coupling plate installed on the shaft part of the operating member, the coupling plate having at least one bulge and one protruding part, with the protruding part and the long axis of the holding part designed to move in alignment with each other; a motor placed in the lock housing; three sensor switches set separately in the lock housing; operating the motor causing the bump of the cog wheel to rotate and push the bulge of the coupling plate, so that the protruding part of the coupling plate of the electric door lock installed in the required position on a left-hand door or right-hand door, selectively touches the two sensor switches adjacent to each other, so as to reach the correct unlocked position or locked position.

The present invention relates to a vehicular door lock which comprises a lock body mechanism and a locking mechanism. The locking mechanism realizes locking of a manual locking switch in a vehicular door and an action for releasing the locking. The lock body mechanism comprises an upper fixing plate and a lower fixing plate, a lock block and an external unlocking pull bar which is equipped between the upper fixing plate and the lower fixing plate. The vehicular door lock further comprises a transition member, a locking slide block, a gripping assembly and an unlocking assembly. Through the gripping assembly and the unlocking assembly in the lock body mechanism, and the cooperation of the locking mechanism and the lock body mechanism, automatic suction from a slightly open state or a semi-locked state to a fully locked state and finally to the locking state for the vehicular door is realized. Furthermore after the vehicular door is realized from the locking state to the fully locked state or the semi-locked state, a function of automatically releasing the vehicular door to the open state is realized.

An electric door lock assembly including a solenoid having a plunger movable between retracted and extended positions, and a mounting bracket for mounting the solenoid to a door or door frame so that the plunger operatively moves along a vertical axis between the retracted and extended positions. A locking arm or bolt is pivotally connected at a proximal end thereof to the plunger. A connecting arrangement causes rotational and linear pivoting of the arm relative to a horizontal axis as the plunger is moved between the retracted and extended positions such that a distal end of the arm moves between unlocked and locked positions relative to a keeper in the door. This arrangement can include the locking arm having an elongate axial slot in which a fixed pin of the mounting bracket is positioned; the pivot pin defining the horizontal axis. The proximal end of the locking arm is pivotally connected to the bottom end of the plunger. Thereby, as the plunger travels up and down the proximal end moves up and down, and the locking arm slides relative to the pin, resulting in the rotational and linear pivoting.

An electric door lock includes a rotatable member, a driving unit, and a manual operating member. The rotatable member is rotatable in first and second rotational directions and is provided with a first protrusion. The driving unit is coupled to the rotatable member, and operable so as to drive rotation of the rotatable member. The manual operating member is rotatable between locking and unlocking positions and is provided with a second protrusion. The first protrusion pushes the second protrusion to permit rotation of the manual operating member between the locking and unlocking positions when the rotatable member is driven by the driving unit to rotate in the first and second rotational directions, respectively. The second protrusion slides over the first protrusion when the manual operating member is driven to rotate between the locking and unlocking positions and when the driving unit is deactivated.

The invention belongs to the technical field of lockset and particularly relates to an electric door lock. The electric door lock comprises a side panel (1), a lock box (2), a main bolt (10), a carriage (9), a main bolt shifting fork (8), a latch bolt assembly (12), a lock core (3), a motor (4) and a circuit board (14), wherein the carriage (9) is connected with the main bolt (10); the main bolt shifting fork (8) drives the main bolt (10) to act through the carriage (9); and the rotating action of the lock core (3) or the motor (4) acts on the carriage through the main bolt shifting fork to drive the main bolt (10). The electric door lock is characterized in that: the motor (4) acts on the main bolt shifting fork through a transmission mechanism; and a joint action between the transmission mechanism and the main bolt shifting fork is provided with a free travel, so the lock core pulls the main bolt shifting fork within a free travel action range and the main bolt extends out of the side panel to lock or retracts to the side panel to unlock.
