Example Embodiment

[0068] So far, the embodiments of the present invention will be described with reference to the drawings. figure 1 and figure 2 This shows a door lock actuator according to an embodiment of the present invention. The door lock actuator is a device that drives a door lock device mounted on a door of a vehicle to lock or unlock the door.

[0069] In the door lock device of this embodiment, the housing 1 contains: an electric motor 2; a worm 3 that rotates under the action of the electric motor 2; and a cam member 4 as a worm wheel that is driven by the worm 3 to rotate around a shaft 4a; It has an arm 5 connected to a lock lever (not shown) that switches the locked and unlocked states of the door lock device, and is pivotally supported by a shaft 6a to be a locking member 6 that can swing on the cam member 4; The switch member 7 can swing coaxially with the lock member 6.

[0070] The locking member 6 can swing between a locking position for locking the door lock device and an unlo...

Abstract

A door lock actuator enabling a motor to not be electrified in the state of mechanically limiting actions is characterized in that a cam component (4) is equipped with a first operation part (13) and a second operation part (14), the first operation part (13) is rotated further at a locking complete angle to enable a switch component (7) to swing towards an unlocking drive region in which a movable contact (20) is contacted with a first fixed contact (27) and a second fixed contact (28) and is not contacted with a third fixed contact (29), and the second operation part (14) is rotated further towards the unlocking direction at a unlocking complete angle to enable the switch component (7) to swing towards a locking drive region in which the movable contact (20) is abutted against the first fixed contact (27) and the second fixed contact (28) and is not abutted against the third fixed contact (29). By swing a locking component (6) to the locking position and the unlocking position, the switch component (7) swings towards a transaction region in which the movable contact (20) is contacted with all the fixed contacts (27, 28, 29).

Description

technical field [0001] The present invention relates to door lock actuators. Background technique [0002] The vehicle door lock actuator rotates a lock lever of a door lock device disposed on a door of the vehicle to a locked position and an unlocked position by driving a motor. [0003] In the conventional door lock actuators described in Patent Documents 1 and 2, when a lock lever is driven, when a predetermined time elapses after energization of the motor, the timer stops energization of the motor. In order to reliably move the lock lever to the locked position or the unlocked position, the energization time to the motor needs to be set slightly longer with some allowance. [0004] However, when the lock lever reaches the lock position or the unlock position, the swing of the lock lever is mechanically restricted, so the motor cannot be rotated even though it is energized, and the motor generates a buzzing sound. In addition, if the motor is energized in the locked or ...
