Novel stopper

Abstract

The invention discloses a novel stopper. The novel stopper comprises a limiting arm, the limiting arm and a protruding part are of an plastic-coated integrated structure, a limiting arm assembly is formed by the limiting arm and the protruding part, a plurality of springs are mounted on the inner side, close to the limiting arm of a housing, blocking sheets are mounted on the outer sides of the springs, a sliding block is mounted at one end of each spring, and the blocking sheets are perpendicular to the sliding blocks. According to the novel stopper, the problem that in the prior art, too much dust and fine sand is likely to be accumulated on the limiting arm is solved, and therefore the quality of door opening and closing of a is improved; a contact face of an existing pull rod type stopper is planar or in a concave arc shape, the fine sand is likely to be accumulated on the stopper, and the more the fine sand is accumulated, the higher the foreign sound risk is; the contact face ofthe novel stopper is in an arc shape, and when dust or fine sand falls onto the surface, the dust or fine sand can slide off by itself along the arc and cannot be accumulate don the contact face of the stopper.

Description

technical field [0001] The invention relates to an automobile door stopper, in particular to a novel stopper. Background technique [0002] The function of the door opening limiter is to limit the opening degree of the door. On the one hand, it can limit the maximum opening of the door to prevent the door from opening too much. On the other hand, it can keep the door open when necessary, such as when the car is parked. On a slope or when there is a general wind, the door will not close automatically. The common door opening limiter is a separate drawstring limiter, and some limiters are integrated with the door hinge, usually on the door. It has a limit function when it is fully open or half open. After a long period of use, the general door stop will accumulate a lot of fine sand on the limit arm. Most of the source of abnormal noise is related to the contact surface between the slider and its limit arm. The abnormal noise generated by fine sand will increase the friction ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a new type of limiter, which overcomes the problem of easy accumulation of dust and too much fine sand on the limiter arm of the prior art (general limiters are mostly The source of the abnormal sound is the abnormal sound generated when the contact surface of the slider and its limit arm is fine sand), which improves the texture of the car door opening and closing
