Abstract

An electric latch for vehicle door is disclosed. The electric latch for vehicle door includes an actuator installed in the vehicle door, a latch part installed in the vehicle door, a pusher part installed in the vehicle door, an actuator driver installed in the actuator, a pull member performing a sliding motion by the actuator driver, a cinching connector that is connected to one side of the pull member and the latch part and transmits a driving force of the actuator to the latch part, and a pusher connector that is connected to other side of the pull member and the pusher part and transmits the driving force of the actuator to the pusher part. The pull member selectively transmits the driving force of the actuator to the latch part or the pusher part.

First claim

What is claimed is:

1. An electric latch for installation in a vehicle door of a vehicle body, the electric latch comprising:
an actuator;
a latch part, wherein the latch part, when installed, is arranged to pull the vehicle door towards an inside of the vehicle body by a driving force of the actuator until the vehicle door is completely closed when the vehicle door is incompletely closed;
a pusher part, wherein the pusher part, when installed, is arranged to push the vehicle door towards an outside of the vehicle body by the driving force of the actuator so as to form a gap between the vehicle door and the vehicle body when the vehicle door opens;
an actuator driver installed in the actuator;
a pull member performing a sliding motion by the actuator driver, the pull member including a cinching pull member linked to the actuator driver, and a pusher pull member coupled to the cinching pull member and linked to the cinching pull member;
a cinching connector connected to the cinching pull member and the latch part, the cinching connector transmitting the driving force of the actuator to the latch part; and
a pusher connector connected to the pusher pull member and the pusher part, the pusher connector transmitting the driving force of the actuator to the pusher part,
wherein the pull member selectively transmits the driving force of the actuator to the latch part or the pusher part,
wherein the latch part includes:
a latch part housing;
a latch pivotally installed on the latch part housing and coupled to the vehicle body;
a pivoting member locking or unlocking the latch; and
a cinching lever configured to rotate the latch in a direction in which the vehicle door is pulled to the inside of the vehicle body,
wherein the cinching connector is connected to the cinching lever, and the cinching lever rotates when the driving force of the actuator is transmitted to the cinching connector,
wherein the pusher part includes:
a pusher part housing;
a rotation lever pivotally installed on the pusher part housing;
a pusher connected to one side of the rotation lever and configured to slide in a direction in which the vehicle door opens; and
a sliding member connected to another side of the rotation lever and configured to slide in an opposite direction to the direction in which the pusher slides,
wherein the pusher connector is connected to the sliding member, and the sliding member slides when the driving force of the actuator is transmitted to the pusher connector.

2. The electric latch for vehicle door of claim 1 , wherein the pusher includes a door open button abutting on the vehicle door and a door open sensor that is able to be pressed by the door open button,
wherein when the door open button is pressed by the vehicle body, the door open sensor is pressed by the door open button and checks an open state of the vehicle door.
