High-energy-storage limiter structure

Abstract

The invention provides a high-energy-storage limiter structure, and belongs to the technical field of automobile limiters. The high-energy-storage limiter structure solves the problem that an existinglimiter structure is large in dust accumulation and abnormal sound risk. The high-energy-storage limiter structure comprises a guide arm; guide grooves are formed in the upper side and the lower sideof the guide arm; a plurality of limiting grooves are formed in each guide groove; the guide arm is slidably sleeved with a limiting part; the limiting part comprises rolling balls capable of rollingalong the guide grooves; the rolling balls can be embedded and positioned in the limiting grooves; dust discharging grooves are formed in the guide arm along the guide grooves; and the dust discharging grooves penetrate through the upper side and the lower side of the guide arm, so that the guide grooves and the limiting grooves which are located in the upper side and the lower side of the guidearm are communicates with each other. The high-energy-storage limiter structure has the advantages of being not prone to dust accumulation and small in abnormal sound risk.

Description

technical field [0001] The invention belongs to the technical field of stoppers for automobiles, and relates to a stopper structure with high energy storage. 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 door stoppers, such as Chinese patent documents disclose door stoppers for motor vehicles [application number: 201420421813.3; authorized announcement number: CN204002175U], which include guide arms, which are slidably sleeved with stoppers. The middle part of the limiter is provided with a ball that rolls and fits with the guide arm. The contact surface between the guide arm and the ball is provided with a guide groove extendin...

AI Technical Summary

Problems solved by technology

However, for the limiter of this structure, in order to realize the mobile positioning of the ball, the chute of the ball chute limiter is generally deep, and the deeper chute is easier to accumulate dust, and the cross section of the chute is concave. The arc shape, the contact between the chute and the ball is surface contact. In the durability test of the limiter with this structure directly adding ash, the number of times the limiter with this structure has abnormal noise is 8,000 times, that is, in During use, the risk of dust accumulation and abnormal noise is very high, which will reduce the quality of car door opening and closing that users can feel most directly
