DOOR LOCK ACTUATOR

Purpose

• Performs lock/unlock switching of the doors electrically based on the signal from the electrical supply unit (ESU).

Function

Lock function

• The door lock actuator operates the built-in motor in the lock direction, and the latch lever will not release even if an inner/outer handle is operated.

Unlock function

• The door lock actuator operates the built-in motor in the unlock direction and the latch lever releases when an inner/outer handle is operated.

Construction

• The door lock actuator has a built-in motor, and the link installed to the motor moves in the lock/unlock direction in conjunction with the motor rotation.

• The link for the inner/outer handle and latch lever can be connected/disconnected by the movement of the link installed to the motor.

Operation

1. The door lock actuator rotates the built-in motor to the lock side.

2. When the motor rotates to the lock side, the link installed to the motor moves in the lock direction, and the link for the inner/outer handle and latch lever release disconnects.

3. When the link connection is disconnected, the latch lever cannot be released even if an inner/outer handle is operated.

Unlock operation

1. The door lock actuator rotates the built-in motor to the unlock side.

2. When the motor rotates to the unlock side, the link installed to the motor moves in the unlock direction, and the link for the inner/outer handle and latch lever release connects.
