Abstract

A door locking apparatus of an automobile is provided wherein inner and outer handles mounted at a door of an automobile for releasing a latch transfer the manipulating force to the latch by an integrated link member, thereby shortening an assembly process of the tailgate by reducing the number of required parts and also reduce the manufacturing cost. The apparatus has an inner handle mounted inside of a door of the automobile, an outer handle mounted outside of the door of the automobiles, a locking device for releaseably locking the door, and link having a first movable member for receiving a manipulating force of the outer handle and a second movable member rotated by the first movable member and the inner handle to release the latch.

Claims

1. A door locking apparatus of automobile, the apparatus comprising:

an inner handle mounted inside of a door of the automobile;

an outer handle mounted outside of a door of the automobile;

a locking device for releaseably locking the door; and

a link having a first movable member for receiving a manipulating force of the outer handle to rotate thereby and a second movable member rotated by the first movable member and the inner handle to release the latch, wherein the second movable member is rotated by the first movable member when the first movable member is rotated, wherein the second movable member is rotated by actuating the inner handle, wherein the first movable member and the second movable member are coaxially and rotably mounted about a rotary shaft, and the first movable member comprises at one side thereof a protruder contacting one side of the second movable member, wherein when the first movable member is rotated, the second movable member is rotated in the same direction by the protruder, wherein only the second movable member is rotated when the second movable member is rotated.

2. The apparatus as defined in claim 1 further comprising:

a first rod for connecting the outer handle to the first movable member;

a second rod for connecting the inner handle to the second movable member; and

a third rod for connecting the latch to the second movable member.

3. The apparatus as defined in claim 1 further comprising a fixing member for rotably supporting the first movable member and the second movable member via the rotary shaft.

4. The apparatus as defined in claim 2, wherein the second rod is a cable having a wire disposed therein and the wire is fixedly connected to the second movable member.

5. The apparatus as defined in claim 1 wherein the second movable member is rotated by actuating the inner handle without rotating the first movable member.
