Abstract

The invention provides a high-energy-storage limiter structure, which belongs to the technical field of automobile limiters. It solves the problem of high risk of dust accumulation and abnormal noise in the existing limiter structure. The structure of the high-energy storage limiter includes a guide arm. Guide grooves are provided on the upper and lower sides of the guide arm. Each guide groove is provided with several limit grooves. The slidable sleeve on the guide arm is provided with a limit piece. The limiter includes balls that can roll along the guide groove, the balls can be embedded and positioned in the limit groove, the guide arm has a dust discharge groove arranged along the guide groove, and the dust discharge groove runs through the upper and lower sides of the guide arm so that it is located on the guide arm The guide grooves on the upper and lower sides and the limit grooves are all connected. The structure of the high-energy storage limiter has the advantages of not easy to accumulate dust and less risk of abnormal noise.

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...
