High-energy door limiter

Abstract

The invention discloses a high-energy door limiter. The high-energy door limiter comprises a limiter main arm and a limiting box penetrated by the limiter main arm, wherein two high-energy compressionsprings and two mobile sliding blocks are symmetrically mounted in the cavity of the limiting box respectively; two high-strength bolts are arranged on two sides of the bottom end of the limiting boxin a pressed manner respectively; a stop reinforced cover plate is fixed at the top end of the limiting box to seal the limiting box; square holes are formed in the center of the stop reinforced cover plate and the center of the bottom end of the limiting box respectively and opposite to each other; the limiter main arm penetrates through the square holes from between the two mobile sliding blocks to be concentrically aligned to a rotary plate part, and the tail end of the limiter main arm and the rotary plate part are riveted; and a sealing part is further arranged between the limiter main arm and the rotary plate part. According to the high-energy door limiter, the closing-aiding energy comfort level and the hand feel are greatly improved in the opening process of the limiter, the quality of the whole car is improved, and meanwhile, external dust is prevented from entering the limiter main arm effectively.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a high-energy door stopper. Background technique [0002] With the continuous improvement of domestic / foreign automobile industry technology, consumers have higher and higher requirements for cars, and the sensory experience of car doors among user groups has become more and more prominent. Domestic car companies have only begun to pay attention to the opening and closing of car doors in recent years. energy comfort and texture. [0003] The existing door stoppers have relatively small assisting closing energy, and have the problems of poor hand feel and texture during use. In addition, external dust is easy to enter the main arm of the limiter, and over time, there will be a certain amount of abnormal noise during the opening and closing of the door, which greatly affects the use of users. [0004] Therefore, how to effectively overcome the above-mentioned tec...
