Hydraulic door stopper

Abstract

The invention discloses a hydraulic type vehicle stopper. The hydraulic type vehicle stopper comprises a shell, and two working cylinders are installed in the shell side by side and mutually communicate through two symmetrically-installed guide tubes; and each working cylinder is slidably provided with a piston, the positions are located between the two guide tubes, and each piston is fixedly connected with a piston rod, wherein one piston rod is movably connected with a stopper support after penetrating out of the front end of the shell, and the other piston rod is fixedly connected with a hinging lug after penetrating out from the rear end of the shell. According to the hydraulic type vehicle stopper, opening angles of a vehicle door are limited, and appropriate damping can be provided in the opening and closing processes of the vehicle door, impact during opening and closing of the vehicle door under conditions of special terrains such as a ramp is reduced, and the hydraulic type vehicle stopper has the advantages that the structure is novel, the service life is long, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of vehicle parts, in particular to a hydraulic door stopper. Background technique [0002] The door stopper is mainly used to limit the opening angle of the car door and provide proper damping when opening or closing the door to avoid accidents such as scratches. [0003] The commonly used door stopper mainly adopts a pull belt structure, including a limit arm and a limit box. A plurality of raised structures with different heights are set on the limit arm, and an elastic rubber block is set inside the limit, and the door is opened and closed. During the process, the elastic rubber block in the limit box is elastically deformed by using the limit arm to slide relative to the limit box, thereby providing damping. However, the damping caused by the deformation of the elastic rubber block is generally small, and there is still a large impact when opening or closing the door under special terrain conditions suc...

AI Technical Summary

Problems solved by technology

However, the damping caused by the deformation of the elastic rubber block is usually small, and there is still a large impact when opening or closing the door under special terrain conditions such as ramps, and it is easy to scratch other vehicles or pedestrians, resulting in accidents. Long-term use It is easy to cause damage to the door hinge
