Centrally-controlled door lock with false lock prevention mechanism

Abstract

The invention discloses a centrally-controlled door lock with a false lock prevention mechanism. The centrally-controlled door lock comprises a seat plate, an outer lock rocker arm, a linkage slide block, a latch hook, and a clamping plate, wherein one end of the outer lock rocker arm is provided with an annular insertion cavity for an outer lock rod; a linkage slide block shaft is fixedly connected to the outer lock rocker arm; a plurality of bulged parts extend out from one side of the latch hook along the plane thereof, and a latch hook linkage shaft is arranged in a rotation area formed by the outer lock rocker arm and an L-shaped end; a plurality of sunken parts extend out from one side of the clamping plate along the plane thereof; when the bulged parts and the sunken parts are engaged, the outer lock rocker arm drives the linkage slide block to rotate towards a direction away from the latch hook linkage shaft, and when the linkage slide block is separated from the latch hook linkage shaft, a vehicle door is locked; and when the bulged parts and the sunken parts are engaged, the outer lock rocker arm drives the linkage slide block to rotate towards the direction of the latch hook linkage shaft, and when the linkage slide block contacts with the latch hook linkage shaft, the vehicle door is unlocked. According to the invention, locking and unlocking of the vehicle door can be controlled simultaneously by virtue of many operations; and moreover, the vehicle door is prevented from being locked due to a misoperation in an unclosed state, thus enough safety is brought to a vehicle owner.

Description

technical field [0001] The invention belongs to the technical field of centrally controlled door locks for automobiles, and in particular relates to a centrally controlled door lock with an anti-mislocking mechanism. Background technique [0002] With the improvement of people's living standards, cars have become a means of transportation for people's daily use. Therefore, the requirements for the safety performance of car door locks are also gradually increasing. It is necessary to ensure that the door can be opened smoothly when needed during parking. [0003] The automobile central control door lock system is installed on the automobile door and the column, which can lock the door reliably and realize the opening and locking function through the internal mechanism. The mechanical locks of existing automobile central control door locks mainly contain reed type door locks, hook spring type door locks and clamping plate type door locks. The reed type door lock cannot bear ...

AI Technical Summary

Problems solved by technology

However, the structure of the clip-type door lock is relatively scattered, and the mechanical actions of various locking and unlocking are not transmitted to the same structural component, and it is impossible to realize remote central control of door safety. Unlocked, extremely inconvenient to use
