Pneumatic ball door stopper

Abstract

The invention discloses an air-pressure ball vehicle door limiter. The air-pressure ball vehicle door limiter comprises a limiting chamber; a limiting rod penetrates through the limiting chamber; a limiting stopper is arranged at one end of the limiting rod; a rotating pin shaft is arranged at the other end of the limiting rod; the limiting chamber is mounted on a vehicle door inner plate; air pressure extension pressing blocks are arranged in the limiting chamber; multiple balls are arranged on the two sides of the limiting rod; the air pressure extension pressing blocks are arranged on the side surfaces of the two sides of the balls on the limiting rod; the air pressure extension pressing blocks comprise extension parts and fixed parts; the fixed parts are cylindrical; and the extensionparts are positioned around the fixed parts, and can move up and down along the fixed parts. In the air-pressure ball vehicle door limiter, through arrangement of the multiple balls, setting of multiple continuous gears can be realized; and the air pressure extension pressing blocks are arranged as the extension parts and the fixed parts, so that fixation of the balls is facilitated, and rotationof the balls is not interfered in the vehicle door operation process.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a pneumatic ball door stopper. Background technique [0002] As the name suggests, the limiter is used to limit the opening degree of the door. First of all, it is to limit the maximum opening of the door. We don’t want a 180-degree rotation screen when the door is pushed. More importantly, we need the door to maintain a certain opening angle. If It is a little less strength or a little wind, and we don't want to see the door bounce itself back. [0003] The use of the limiter facilitates the opening and closing of the car door. In the prior art, the limiter generally adopts a pull rod limiter, and utilizes the different protrusions and depressions on the limiter arm to realize the gear limit. Generally speaking, there are several There are several gears for each bump. When the elastic material in the limit box squeezes the groove on the limit arm with the swit...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is that the existing car door limiter is not stable in position, and it is easy to slide back and forth when it is in the limit position.
