A dust discharge structure for a door opening limiter

Abstract

The invention provides a dust discharge structure of a car door opening limiter, which belongs to the technical field of auto parts. It solves the problems of abnormal sound and jam in the existing door opening limiter. The limiter includes a limit arm, and several limit pits are arranged at intervals on the limit arm. The dust discharge structure includes several dust discharge grooves arranged on the limit arm, and the inner end of the dust discharge groove extends to the limit In the middle of the pit, the outer end of the dust discharge trough runs through the side of the limit arm, along the direction from the inner end of the dust discharge trough towards the outer end, and the bottom of the dust discharge trough is inclined toward the middle of the limit arm thickness direction. The dust discharge structure of the door opening limiter has the advantage of avoiding abnormal noise caused by sand and dust accumulated in the limit pit.

Description

technical field [0001] The invention belongs to the technical field of automobile 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 degree of the door. On the one hand, it can limit the maximum opening of the door to prevent the door from being opened 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, such as Chinese patent documents disclose a dust-proof door opening stopper [Application No.: 201910130804.6; Application Publication No.: CN109826517A], which includes a limiter rotatably arranged on the vehicle body. The limit arm assembly and the limiter box assembly fixed on the door and slidably connected with the limiter arm assembly, the limiter box assembly can slide along the axis d...

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
