Abstract

The invention discloses a damping type car door installation structure. The damping type car door installation structure comprises a car body, a car door, a damping hinge and a car door limiter, wherein the car body and the car door are connected through the damping hinge and the car door limiter; a cam spring abutting structure is arranged in the damping hinge; the car door limiter comprises a shell; a first hydraulic oil cylinder and a second hydraulic oil cylinder are arranged in the shell, and the first hydraulic oil cylinder and the second hydraulic oil cylinder are opposite in direction, are both arranged in the length direction of the shell and communicate with each other through two guide tubes; a limiter holder is hinged to the front end of a piston rod A of the first hydraulic oil cylinder; a piston rod B of the second hydraulic oil cylinder penetrates out along the rear end of the shell; a groove for containing the shell is formed in the position, corresponding to the end of the piston rod B, of the car door; a second hinge pin is fixedly arranged in the groove; and the end of the piston rod B is hinged to the second hinge pin. In the opening or closing process of the car door, the hinge and the limiter achieve the resistance effect to the car door simultaneously, and impact caused by opening or closing of the car door under special terrain conditions like slopes is reduced. The damping type car door installation structure has the advantages that the structure is novel, the service life is prolonged, and reliability is high.

Description

technical field [0001] The invention relates to a vehicle component, especially a damping type vehicle door installation structure. Background technique [0002] The car door is connected to the body through hinges, and is usually equipped with a door stopper to limit the opening angle of the 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...
