Abstract

The invention discloses an automobile door lock, which comprises a bracket and a lock body arranged on the bracket, wherein the lock body is provided with an opening rocker arm, a ratchet wheel and a pawl; the ratchet wheel and the pawl are mutually meshed; the impact position of the pawl and the lock body is provided with a buffer block; the buffer block is composed of a cross rod and a longitudinal rod and is in a T-shaped structure; the longitudinal rod is provided with a through hole; the through hole is matched with a boss arranged on the lock body; and the buffer block is fixed on the lock body. The automobile door block has the advantages of simple structure and low cost and is convenient to manufacture. The impact position of the pawl and the lock body is provided with the buffer block so as to lower the speed of the pawl impacting the lock body, and noise is effectively avoided, so that the quality of the whole automobile is improved and the client satisfaction degree is improved.

Description

Automobile door lock

Technical field

The present invention relates to a kind of lock, relate in particular to a kind of automobile door lock.

Background technology

Along with developing rapidly of auto industry, people also rise to the composite request of automobile gradually.The appearance design, the interior trim design that rise to automobile from performance indications such as the discharge capacity of only paying attention to automobile, oil consumption in the past also propose specific requirement, and the requirement that goes so far as the comfort level that the present driving to automobile experiences, takes is also increasingly high.

As everyone knows, automobile door lock is requisite parts in the present motor vehicles for civilian use.The automobile door lock that uses in the market; When people implement the action of switch door, because the effect that is engaged on spring force of door lock ratchet and pawl collision down produces bigger noise; And this noise is not in the scope of control; Be easy to cause client's sense of discomfort,, cause client's complaint and complaint easily in the epoch that current people improve quality of the life day by day; Therefore, the automobile door lock that is necessary to design a kind of simple possible and does not produce radiography in fact.

Summary of the invention

The objective of the invention is to provides a kind of automobile door lock to the problems referred to above, produces the big problem of noise to solve the orthodox car door lock at closing time opening.

The objective of the invention is to realize through following technical scheme:

A kind of automobile door lock; Comprise support and be arranged at the lock body on the support; Said lock body is provided with opens rocking arm and intermeshing ratchet and pawl, and the bump place of said ratchet and lock body is provided with buffer stopper, and said buffer stopper is made up of cross bar and vertical pole; Be T type structure, be fixed on the lock body.

Preferably, said buffer stopper is processed by elastomeric material.

Further, said ratchet is fixed on the lock body through the ratchet locating shaft, and is provided with the ratchet return spring between ratchet and the lock body.

Further, the vertical pole of said buffer stopper is provided with through hole, and the projection that is provided with on said through hole and the lock body matches, and buffer stopper is fixed on the lock body.

Beneficial effect of the present invention does; Said vehicle door lock structure is simple, easily manufactured, with low cost; It sets up buffer stopper through the bump place at ratchet and lock body, thereby reduces the speed of ratchet bump lock body, effectively avoids noise to produce; Thereby improve the quality of car load, improve client's satisfaction.
