Novel inner release mechanism of vehicle door lock

Abstract

The invention discloses a novel inner release mechanism of a vehicle door lock. The mechanism comprises an inner release arm, a child lock connecting rod, a release rod and a pawl, wherein the inner release arm and the child lock connecting rod, the release rod and the pawl can be respectively and rotationally positioned on the inner wall of the vehicle door lock; the inner release arm pushes the child lock connecting rod to rotate; the child lock connecting rod pushes the release rod to rotate; the release rod drives the pawl to rotate; the inner release arm is provided with a mounting part connected with a pull wire or a pull rod; and the release rod and the pawl coaxially rotate. The mechanism realizes the driving through coaxially and fixedly connecting the release rod with the pawl; as the inner release arm and the child lock connecting rod are coaxially hinged, various connecting mechanisms are effectively decreased, the relative slip of the release rod and the pawl and the inner release arm and the child lock connecting rod is eliminated, and the slip friction loss is reduced; as the inner release arm is closer to a lock body mounting surface, the inner release structure is integrated in a lock body shell; and the mechanism has the advantages of simple structure, small size, guarantee of water prevention, dustproof performance and convenience for design and manufacturing.

Description

technical field [0001] The invention relates to an inner release mechanism of an automobile door lock, in particular to a novel inner release mechanism of an automobile door lock. Background technique [0002] The inner release mechanism of the door lock of the car drives the inner release arm to move by operating the handle on the inner side of the door, and the inner release arm drives the child lock link to rotate, and the child lock link is pushed and rotated by the inner release arm to drive the release lever to rotate, and the release lever The rotation will bring the pawl to rotate, and then realize the release of the car door lock. In the conventional structure, the release lever and the pawl are driven by the linkage mechanism. The structure is complex and takes up a lot of space. There is mutual sliding, and the release lever has a large operating force arm for the pawl, which consumes a lot of energy. Contents of the invention [0003] In order to make up for t...
