Rubber spring vibration-dampening chair

Abstract

The invention relates to a rubber spring bumper seat which can be used in vehicle, comprising: a headrest (1), a backrest (2), a regulating knob (3), and an upper connection soleplate (5) of cushion (4). Wherein, the headrest (1) is connected to the upper part of backrest (2) whose lower part is connected to the upper connection soleplate (5) via the regulating knob (3); the cushion (4) is on the upper connection soleplate (5) under which a guide pole (9) is mounted; the upper end of guide pole (9) is mounted under the upper connection soleplate (5) via the clamp nut (10); the guide muffle (8) is mounted on the lower connection soleplate (7); the lower part of guide pole (9) inside the guide muffle (8) can slide freely; the rubber spring (6) is sheath outer the guide pole 99) while its upper end is connected to the upper connection soleplate (5) and its lower end is connected to the lower connection soleplate (7).

Description

technical field [0001] The invention is a damping device suitable for automobile seats, which belongs to the technical field of design and manufacture of automobile parts. Background technique [0002] At present, the existing car seats are ordinary seats, and the stiffness of the seat spring support remains unchanged. When passengers of different weights ride, the natural frequency of the seat-passenger system changes greatly, and it is difficult to avoid the uncomfortable frequency range of the human body. Ordinary springs have small damping coefficients, poor energy absorption, and poor vibration reduction effects. As a result, vehicles without additional hydraulic damping shock absorbers have poor ride comfort, and long-term rides are likely to cause work fatigue and production accidents. Contents of the invention [0003] Technical problem: The object of the present invention is to provide a car rubber spring damping seat that can be widely used in cars. The seat can ...

Ordinary springs have small damping coefficients, poor energy absorption, and poor vibration reduction effects, resulting in poor ride comfort when there is no additional hydraulic damping shock absorber, and long-term rides are likely to cause work fatigue and production accidents
