Automotive door lock system for preventing deadlocking caused by frontal collision of automotive door

Abstract

The invention relates to an automotive door lock of an automobile. The automotive door lock comprises a lock body fixedly connected to an automotive door, wherein the middle part of a lock stopping plate of the lock body is hinged with the framework of the lock body; the end of the lock stopping plate is hinged with the rear end of a transverse bumper; the front end of the transverse bumper is hinged with a rotary clip; the rotary clip is hinged with the automotive door; a vertical bumper is hinged with the rotary clip; and the vertical bumper and the transverse bumper form axial transmission fit along two bumper shafts through the rotary clip. The automotive door lock is characterized in that: the rear end of the transverse bumper is hinged with the lower end of the lock stopping plate; and when a vehicle knocks the transverse bumper from the front side to move forwards so as to pull the lower end of the lock stopping plate to move forwards, the lock stopping plate inevitably anticlockwise rotates around a hinged shaft at the middle part, and the lock stopping plate drives a lock stopping pull rod to act to make the lock body in an unlocking state so as to ensure that a driver can successfully escape. The automotive door lock has the advantages of great improvement on use safety, low cost of an automotive door lock system, wide use, and suitability for modification of old-style lock systems.

Description

technical field [0001] The invention relates to a door lock of an automobile. Background technique [0002] Such as figure 1 As shown, the assembled structure of the door lock developed before the 1980s is: the lock body is located at the rear end of the door frame, the rear end of the transverse safety rod 2 is hinged to the upper end of the locking plate 1, and the middle of the locking plate 1 It is hinged with the lock body frame, the front end of the transverse safety rod 2 is hinged with the rotating clip 3, and the rotating clip 3 is hinged with the lower end of the door and the vertical safety rod 4, so that the horizontal and vertical safety rods 2 and 4 are formed by the rotating clip 3 along the axis of the two rods. In other words, the movement of one pull rod in the axial direction will inevitably drive the other pull rod to move in the direction of its axial length; The lock plate 1 rotates clockwise, and drives the lock push rod 5 hinged on it to move upward...

AI Technical Summary

Problems solved by technology

But such a structure is unreliable, first of all it cannot avoid the forward movement and deformation of the transverse safety rod 2, and when the vehicle collides fiercely, the heavier rotating clip 3 will still rotate and cause the door to be locked.

And this also increases the weight of the vehicle, which is not in line with the technological development trend of energy saving and emission reduction
