Problems solved by technology
For example, an air damper is used in the glove box of the passenger car, which has a cylindrical cylinder and a piston that can move back and forth along the cylinder axis. When the glove box is opened, when the piston moves axially in the above damper structure, Resistance is generated through the small hole, and it is inevitable that resistance will be generated during the entire stroke of the piston moving back. However, due to ergonomics and the convenience of opening the glove box, it is often necessary to generate only a small or small amount in the initial strok

Embodiment Construction
[0025] Examples of the present invention Figures 1 to 8 As shown, an air damper includes a cylinder 1, a piston 4 and a piston rod 3, the closed end of the cylinder 1 is provided with a bottom cover 5, and the other end of the cylinder is provided with an end cover 6, and the piston 4 is synthesized Formed from a resin material, the piston 4 is set in the cylinder body 1 in a coaxial free reciprocating manner, a hole 41 is provided on the piston 4, one end of the piston rod 3 is connected to the piston 4, and the other end faces the cylinder The end of the body opposite to the closed end of the cylinder protrudes, and the piston forms high and low damping when moving in the cylinder, thereby meeting different requirements.
[0026] Such as figure 1 As shown, in the structure of the air damper of the present invention, the cylinder body 1 is closed with the bottom cover 5, and the piston rod 3 is slidingly fitted with the end cover 6. At the same time, the cylinder body 1 is ...

Abstract
The invention discloses an air damper comprising a cylinder body, a piston and a piston rod. The closed end of the cylinder body (1) is provided with a bottom cover and the bottom cover is closely engaged with the cylinder body. The piston is molded from synthetic resin materials. The piston is arranged inside the cylinder body by means of coaxial random reciprocating movement. The piston is provided thereon with a hole. One end of the piston rod is connected with the piston, and the other end thereof extends outside one end of the cylinder body, opposite to the closed end of the cylinder body. The piston moves inside the cylinder body to produce high/low damping. A pyramidal chamber and a cylindrical chamber inside the cylinder body can be randomly combined, so as to realize the state change from high damping to low damping, or state change from low damping to high damping, or state change from low damping to high damping and then to the low damping, or a random combination thereof.
Description
【Technical field】 [0001] The invention relates to an air damper, especially a piston type air damper, which can freely reciprocate in a cylinder to generate damping. 【Background technique】 [0002] In the fields of home appliances and automobiles, air dampers are often used in order to create a high-end feeling of slowly falling when the lid is opened. For example, an air damper is used in the glove box of the passenger car, which has a cylindrical cylinder and a piston that can move back and forth along the cylinder axis. When the glove box is opened, when the piston moves axially in the above damper structure, Resistance is generated through the small hole, and it is inevitable that resistance will be generated during the entire stroke of the piston moving back. However, due to ergonomics and the convenience of opening the glove box, it is often necessary to generate only a small or small amount in the initial stroke of opening. No damping, falling quickly at an angle, an...
