Automobile self-sucking door lock

Abstract

The invention aims at providing an automobile self-sucking door lock which enables an automobile door to be easily closed, is low in noise and can prolong the service life of the door lock and an automobile door hinge. The automobile self-sucking door lock comprises a locking mechanism, a driving mechanism and a first position sensor, the locking mechanism comprises a fixing plate, an open slot isformed in the fixing plate, a spring bolt is rotationally fixed to the fixing plate, one end of the spring bolt is a linkage end, the other end of the spring bolt is a locking end, the linkage end islinked with a pull wire, and the end, far away from the locking mechanism, of the pull wire and a sliding block are fixed; when the spring bolt rotates to one side to reach the limiting position, thelocking end leaves the open slot, and the linkage end drives the sliding block through the pull wire to forwards move; when the spring bolt rotates to other side, the locking end rotates to the sideof the open slot, and the linkage end pushes the sliding block to move backwards through the pull wire; and when the first sensor detects that the sliding block is moved backwards, the driving mechanism controls the sliding block to continuously move backwards, and therefore the sliding block pulls the spring bolt through the pull wire to enable the spring bolt to be rotated again.

Description

Technical field [0001] The invention relates to an automobile door lock, in particular to an automobile self-priming door lock. Background technique [0002] For cars currently on the market, if the door closing force is too small during the door closing process, the door (the side door and the tail door of the car) cannot be closed; if the door closing force is too large, the door will impact on the body and generate loud noise, which will cause the car door to lock. The service life of door hinges and door hinges is also affected, and this impact and noise greatly affect the car owners or consumers (customers, passengers) experience of using the car. Summary of the invention [0003] The purpose of the present invention is to provide a self-priming car door lock that can close the door easier, has lower noise, and can extend the service life of the door lock and the door hinge. [0004] In order to achieve the above objective, the present invention adopts the following technical ...

AI Technical Summary

Problems solved by technology

[0002] In the cars currently on the market, too little closing force may cause the doors (car side doors and tailgates) to fail to close during the closing process; too much closing force will cause the door to impact the body and generate loud noise, which will have a negative impact on the car door lock. And the service life of the door hinge is also affected, and this impact and noise greatly affect the car owners or consumers (customers, passengers) experience
