A car seat shock absorber

Abstract

A shock absorbing device for a car seat, comprising a seat, one side of the seat is hinged with a backrest, a base is provided under the seat, and a buffer and shock absorbing mechanism is respectively provided at four corners of the bottom surface of the seat to form a total of four A buffer and shock absorbing mechanism, the base is provided with a chute; the buffer and shock absorbing mechanism includes an electric telescopic rod, a spring barrel, a slider and a spring, the spring and the slider are arranged in the spring barrel, and the upper end of the spring is connected with the bottom surface of the slider , the lower end is connected with the bottom surface of the spring tube, the lower end of the telescopic slider of the electric telescopic rod stretches into the spring tube and is fixedly connected with the upper surface of the slide block, the bottom of the spring tube is contained in the chute, and the electric telescopic rod is connected with the automobile power supply. The invention has good shock absorption performance and ventilation performance, and improves the comfort of use.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a shock absorbing device for an automobile seat. Background technique [0002] Generally, the same car will often be driven by different people, and different people have different requirements for the height of the driver's seat due to their different heights. In the existing automobiles, the car seat can be adjusted front and rear and the backrest angle, but the structure is complicated, and the height adjustment of the seat cannot be realized, which cannot meet the needs of people of different heights for seat height adjustment, and affects the driving experience. Comfort and safety. In addition, shock absorbers are installed under the seats, and ordinary shock absorbers generally have constant cushioning force characteristics, so low cushioning force characteristics can improve driving comfort, but cannot ensure vehicle stability. On the contrary, a high cushioning forc...

AI Technical Summary

Problems solved by technology

In the existing automobiles, the car seat can be adjusted front and rear and the backrest angle, but the structure is complicated, and the height adjustment of the seat cannot be realized, which cannot meet the needs of people of different heights for seat height adjustment, and affects the driving experience. Comfort and Safety

In addition, shock absorbers are installed under the seats, and ordinary shock absorbers generally have constant cushioning force characteristics, so low cushioning force characteristics can improve driving comfort, but cannot ensure vehicle stability

On the contrary, high cushioning force characteristics can maintain the stable posture of the vehicle, but lead to a decrease in driving comfort

Thus, conventional shock absorbers cannot control the cushioning force characteristics in response to changes in road conditions or vehicle attitude

[0003] In addition, when seat heating is required, it is necessary to install a separate heating resistance wire inside the seat or use the car air conditioner to heat it, so that the fuel consumption is high and the cost is high.
