Automobile door lock

Abstract

A lock for the door of car is composed of a lock body, a locking bolt and a drive mechanism. Said lock body has a fastening plate, and the first and the second detents matched with said fastening plate to provide three locking states: semi-locking, intermediate locking and full locking.

Description

technical field [0001] The present invention relates to locks, and more particularly to automobile door locks. Background technique [0002] The car door lock mainly includes a lock body, a lock catch and a driving mechanism. The lock body is the main part of the door lock and is generally installed on the car door. The lock buckle (sometimes also called a lock ring or a lock pin) is a part that cooperates with the lock body, and is usually installed on the vehicle body to correspond to the lock body. The driving mechanism refers to the transmission components of actions and forces such as key unlocking and handle unlocking. [0003] At present, most of the lock bodies adopt a counter force two-part structure, and two states of semi-locking and full-locking can be easily realized through a clamping plate and a pawl. [0004] Fig. 1 is a schematic diagram of a lock body in a half-locked state in the prior art, and Fig. 2 is a schematic diagram of a lock body in a fully loc...

AI Technical Summary

Problems solved by technology

[0009] However, in this traditional automobile door lock, through the cooperation between the clamping plate and the pawl, the lock body only has two states of half-locked and fully locked. Therefore, in the locked state of the door lock, the not high strength

When an accident occurs that deforms the vehicle body or the door lock is subjected to a large impact force, the door lock may be damaged, so that the occupants in the car are thrown out of the car

[0010] In addition, in the operation of this kind of traditional car door lock, because the reaction force of the door of different cars varies greatly, when closing the door, if the door reaction force of a certain type of car is relatively large, the passenger may be due to the force applied when closing the door. It is too small to lock the door lock in the fully locked position, and the half lock can bear much less load than the full lock, so there will be safety hazards when the door is not closed tightly
