Dust discharge structure of vehicle door opening limiter

Abstract

The invention provides a dust discharge structure of a vehicle door opening limiter, and belongs to the technical field of automobile parts. The problem that abnormal sounds and clamping exist in existing vehicle door opening limiters is solved. The limiter comprises a limiting arm, and multiple limiting concave pits are arranged on the limiting arm at intervals. The dust discharge structure comprises multiple dust discharge grooves arranged on the limiting arm. The inner ends of the dust discharge grooves extend to the middles of the limiting concave pits, the outer ends of the dust dischargegrooves penetrate through the side of the limiting arm, and the groove bottoms of the dust discharge grooves are arranged by inclining towards the middle, in the thickness direction, of the limitingarm in the direction that the inner ends of the dust discharge grooves face the outer ends. The dust discharge structure of the vehicle door opening limiter has the advantage of avoiding the situationthat abnormal sounds are caused due to the fact that sand dust is accumulated in the limiting concave pits.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a dust discharge structure of a door opening limiter. Background technique [0002] The car includes a door stopper. The door stopper is a part that limits the opening 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 open the door when needed. If the car is parked on a slope or the wind is blowing, the door will not close automatically. [0003] Existing automobile door stoppers, for example, Chinese patent literature discloses a dust-proof door opening stopper [application number: 201910130804.6; application publication number: CN109826517A], which includes a limiter that is rotatably arranged on the vehicle body. The limiter arm assembly and the limiter box assembly fixed on the car door and slidingly connected with the limiter arm assembly, the limiter box assembly can slide along ...

AI Technical Summary

Problems solved by technology

[0004] The limiter of this structure, the limit arm assembly includes a steel core set inside and a plastic cover covering the steel core. There are several card slots on the plastic cover. The two side walls of the plastic sleeve and the bottom of the card slot are flat. During use, the sand and dust will fall on the bottom of the card slot. However, since the bottom of the card slot is flat, the movement effect of sand and dust toward the two sides is not ideal. After a period of use, the contact surface of the limit slider and the limit arm has the problem of wear and tear, resulting in abnormalities when the door is opened and closed. ring

At the same time, the two side walls of the clamping groove of the limiter with this structure are relatively steep, and the depth of the clamping groove is relatively deep. The switch is not smooth enough
