door stopper

Abstract

The invention discloses a vehicle door limiter, which relates to the technical field of automobile parts. The limiter includes a limit bracket, a limit pull plate and a limit assembly, the limit assembly is fixedly connected with the door, one end of the limit bracket is connected with the vehicle body, and the other end of the limit pull plate One end extends into the space inside the car door after passing through the limit assembly, and the limit assembly is used to limit the limit pull plate so that the opening and closing angle of the car door is fixed. The door stopper can eliminate the movement noise of the limiter pull plate when opening and closing the car door, avoid the influence of rainwater corrosion and adverse effects caused by internal wear of the stopper, and prolong the service life of the door stopper assembly.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a door stopper with long service life and good stopper effect. Background technique [0002] At present, with the development of science and technology, people's living standards have improved, and the requirements for car performance have become higher and higher; the door stopper is an auto part that limits the position of the car door, and has the ability to limit the opening and closing of the car door. Function, the door stopper is generally arranged between the upper and lower hinges of the door, which can limit some specific positions of the door so that the door can neither close nor open itself. On the one hand, it can limit the maximum opening angle of the door to prevent the outer panel of the door from colliding with the car body; on the other hand, it can control the door to keep open according to actual needs, for example, when the car is parked on a slope ...

AI Technical Summary

Problems solved by technology

[0004] 1) One of the common types of limit boxes is formed by stamping sheet metal. This kind of limit box is called a metal box; because in the case of artificial door opening angle overload, the associated limit When the device assembly is working, it is easy for the limit pull plate to squeeze the limit box, resulting in deformation of the metal box;

[0005] 2) The metal box described in case 1) is divided into two parts: the cover plate and the box. The metal cover plate and the box are generally fixed to each other by riveting. In this case, the plastic inside the stopper slides during the working process The block will move up and down linearly with the waveform of the limit pull plate, and the peripheral wall of the slider will collide with the metal cover plate and the box wall to cause corresponding hard collision and frictional movement, which will easily produce abnormal movement noise, and the metal surface coating will also be subject to corresponding wear and tear. After reaching a certain level, after the rainwater enters, chemical reactions such as corrosion and rust will occur with the metal surface whose coating is damaged, which will further aggravate the adverse reaction of the slider's frictional noise;

[0006] 3) Under normal circumstances, the bolts and the above-mentioned metal limit box are fixed by riveting. In the actual market feedback, occasionally the bolts will fall off, which brings inconvenience to the limiter maintenance and affects the customer experience;

[0007] 4) Under normal circumstances, the shock-absorbing block made of TPU and other materials is assembled on the pull plate and moves with the limit pull plate. During this process, it is easily damaged due to the extrusion of the metal frame structure;

[0008] 5) Due to the influence of weather or other environmental factors, rainwater and muddy water will intrude into the limit box inside the limit box. Since there is no corresponding drainage channel, it is easy to cause rainwater and mud water to accumulate inside the limit box, making the limit box Abnormal noise occurs when the device assembly is working
