An electric lock includes an input switching clutch for selectively transmitting the electric or manual driving force to the output line. The input switching clutch includes an outer ring that rotates together with an electrically driven input gear, and an inner ring which rotates together with an output gear. Wedge-shaped spaces are defined between the outer ring and the inner ring. Two rollers are mounted in each wedge-shaped space and are biased toward the narrow portions of the wedge-shaped space by a coil spring also mounted in the wedge-shaped space. The input switching clutch further includes an unlocking piece having crossbars inserted at both circumferential ends of the respective wedge-shaped spaces, and coupled to a manually driven input shaft so that its rotation can be transmitted thereto; and a torque transmission mechanism for transmitting the rotation of the manually driven input shaft to the inner ring.

Disclosed are various embodiments of lock devices, systems, and methods. A lock of the application can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock can be made from an assembly of parts that have locating features that require one way installation/assembly. The lock can include an internal power source capable of driving electronics used to determine handedness of a door.

In some embodiments, a clutch for a door lock may include an output gear including a plurality of inner detents and a lag plate rotatable relative to the output gear and configured to generate friction when the lag plate rotates. The clutch may also include an input cam configured to be coupled to an output shaft of an actuator, where the input cam is configured to switch between an engaged state and a disengaged state. The clutch may also include a ball bearing configured to engage one of the plurality of inner detents when the input cam is in the engaged state. The ball bearing may also be configured to disengage from the plurality of inner detents under frictional force generated by the lag plate when the input cam is in the disengaged state and the output gear is rotated by an external force.

Lock devices, systems, and methods including an internal mechanism to permit backdriven operation and lost motion operation. In one form, the lock includes an assembly of parts with locating features that assist in those parts being assembled with other parts of the assembly in a single, relative orientation. Further, lost motion may be utilized to accommodate manual displacement of one or more components that can also be displaceable, in some embodiments, via operation of a motor. The lock can also include an internal power source capable of driving electronics used to determine handedness of a door.

A power lock actuator is provided for a door lock mechanism of a vehicle. The actuator includes an electric motor, a linear drive, and a slip clutch between the motor and the linear drive. The clutch includes a dual-lobe pinion for pulsed energy transmission from the motor to the linear drive, to provide soft starts and stops, which extend the life of the drive assembly 26. The linear drive includes a screw with multiple, discontinuous male thread segments to minimize friction with female threads on the extendible and retractable carriage, thereby minimizing wear between the screw and the carriage.
