Abstract

The invention discloses an automobile door lock mechanism which includes a base plate, a lock tongue and a first pawl. The lock tongue and the first pawl are mounted on the base plate, and the lock tongue and the first pawl are matched to realize a half-lock state and a full-lock state of the automobile door lock mechanism, and the direction of the locking pressure of the lock tongue to the firstpawl is toward the release direction of the first pawl. In the embodiment, since the pressure of the lock tongue to the first pawl points to the release direction of the first pawl, in the process that the first pawl rotates in the releasing direction, the lock tongue also moves in the ejecting direction, the instantaneous pressure of disengagement on a meshing face of the lock tongue and the first pawl is reduced, and the generated noise is low.

Description

technical field [0001] The invention relates to the technical field of automobile door locks, in particular to an automobile door lock mechanism. Background technique [0002] The lock body, lock catch and driving mechanism are the main components of a car door lock. The lock body is usually installed on the car door and has the functions of locking, unlocking, securing and disarming, and is the main part of the door lock. The lock catch is generally installed on the vehicle body, and cooperates with the lock body to realize the function of locking after closing the door. The drive mechanism generally refers to the drive and transmission components that realize the door lock function. [0003] Inside the lock body, at present, a dead bolt and a pawl are mostly used to realize two working states of half lock and full lock. Corresponding to the two states, a half-lock contact surface and a full-lock contact surface are respectively provided on the deadbolt. Through the coo...
