Automobile rotating door limiter

Abstract

The automobile rotating door limiter comprises a limiter main arm, a long hole is formed in the limiter main arm in the length direction of the limiter main arm, and the two ends and the middle of the long hole are widened to form limiting parts; the upper surface and the lower surface of the limiter main arm are planes; an upper sliding block is installed on the upper surface of the limiting stopper main arm, and a lower sliding block is installed on the lower surface of the limiting stopper main arm. An upper elastic piece is installed above the upper sliding block, and a lower elastic piece is installed below the lower sliding block. The connecting bolt sequentially penetrates through the upper elastic piece, the upper sliding block, the long hole, the lower sliding block and the lower elastic piece to be connected with a connecting nut. The middle of the connecting bolt is sleeved with a limiting spring. Y-direction limiting is adopted, the long-strip-shaped hole is formed in the limiting stopper main arm, the width of the inner wall in the hole is changed, the limiting spring passing through the long-strip-shaped hole rubs against the inner wall of the long-strip-shaped hole, the limiting force on the limiting stopper is changed through the change of the width of the inner wall of the long-strip-shaped hole, and therefore the function of limiting the automobile door is achieved.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a stopper for an automobile rotary door. Background technique [0002] With the development of technology, people have higher and higher requirements on the performance and quality of automobiles. Automobile door stopper is a key component of automobile door opening and closing. The rotary door stopper is generally arranged in the middle of the upper and lower hinges. As required, keep the doors open when the car is parked on a ramp or in windy conditions. The limit function and quality of the limiter is an important indicator for consumers to experience the comfort of the car. [0003] The existing technical scheme adopts the Z-direction limit, the main arm of the limiter is designed as a concave-convex curved surface in the Z direction, the slider in the limit box is close to the limit arm under the action of the spring, and the limit arm is screwed to the vehicle body through the br...

AI Technical Summary

Problems solved by technology

Both the slider and the spring of the limiter are located in the limit box. During the opening process of the car door, the slider moves close to the limit arm. The upward concave and convex curve of the limit arm Z may cause the slider to be out of position or misaligned, causing the door to open and close. During the process, the limiter makes abnormal noise
