The invention discloses an air damper and a car door comprising the same. The air damper comprises a damping tube. The two ends of the damping tube are provided with end covers correspondingly. Each end cover is provided with a throttle hole. The middle section of the sidewall of the damping tube is provided with a straight slot. A piston is arranged in the damping tube. The piston comprises two piston bodies. The piston bodies are connected through a piston rod. A connecting rod is arranged in the middle position of the piston rod. The connecting rod extends out of the damping tube through the straight slot. Each piston body is provided with a plurality of through holes for mounting circulation valve plugs. Diaphragm springs are arranged between the circulation valve plugs and the pistonbodies. The air damper is mounted on a car door frame and is connected with an actuation mechanism of the car door. Impact noise in the car door opening and closing process can be effectively reduced.
Description
technical field [0001] The invention belongs to the technical field of vehicle vibration reduction and noise reduction, and in particular relates to an air damper and an automobile door using the damper. Background technique [0002] With the rapid development of the modern automobile industry and the improvement of people's living standards, people have put forward higher and higher requirements for automobiles, and more attention has been paid to the vibration and noise performance of automobiles. The existing bus doors have no damping during the opening and closing process, resulting in no attenuation of speed during the door opening and closing process, forming a large impact at the end of the journey, resulting in a large impact noise, which seriously affects the ride comfort , but also increases the wear and tear of the door components. [0003] The process of opening and closing the door can be divided into two stages. The first stage: in the long period before the ...
