Magnetic control valve for air suspension seat lift

Abstract

The invention relates to a magnetic force control air valve for lifting an air-suspending seat. The magnetic force control air valve comprises a valve seat, an air inlet valve body fixed to the valve seat, an exhaust valve body fixed to the valve seat and a transmission control arm; an air inlet valve element and a first spring are installed in the air inlet valve body, the front end of the air inlet valve body is closed, the back end of the air inlet valve body and the valve seat are sealed, and the two ends of the first spring act on the air inlet valve element and the air inlet valve body; and the valve seat is provided with a first air inlet and a first air outlet which are matched with the air inlet valve element. After the magnetic force control air valve is adopted by the automobile air-suspending seat, the automobile air-suspending seat can adapt to vertical jigging of a road so as to keep the unchanged height, the extremely-high damping self-adaption performance is achieved, a comfortable and safe driving environment is provided for a driver, driving fatigues of the driver are effectively reduced, and the driving safety of the driver is guaranteed.

Description

technical field [0001] The invention relates to a magnetic force control air valve for lifting and lowering an air suspension seat. Background technique [0002] The ride comfort, ride comfort, safety and operation convenience of the car driver's seat have always been important indicators to measure the seat design, and the most important core technology in the design is the shock absorption and cushioning technology of the seat. At present, airbags and height control valves are widely used as shock absorbing and buffering components in foreign countries, especially in high-speed buses, luxury city buses, and medium and heavy trucks in Europe and America. The utilization rate has reached 98%. above. [0003] Since the 1950s, Chinese enterprises have continuously developed rubber airbags with independent intellectual property rights and suitable for my country's characteristics after digesting and absorbing foreign technology. However, at present, the research on airbags an...

AI Technical Summary

Problems solved by technology

However, at present, the research on airbags and height control air valves in my country is still in its infancy, and most seat manufacturers still use mechanical springs as shock absorbing components for seats. , and the cost of importing airbags and height control valve components from abroad is too high, forming a bottleneck, making it impossible for China to make major breakthroughs in this field, and the technical gap is serious

[0004] At present, foreign air suspension seat lifting systems use height control valves, cams, gears, etc. to control the opening and adjustment of height valves in a contact manner, so as to control the inflation and deflation of airbags. The structure is complex and the control seat takes up a lot of space. The cost of chair suspension is higher

However, most domestic seats still use mechanical springs to adjust the softness, hardness and height of the seat. Very few seat manufacturers rely on imitating foreign seats and using cams and gears to control seat suspension to achieve shock absorption. Because they have not mastered the core technology It often makes the product cost inflated, loses the original competitiveness and at the same time it is difficult to guarantee product quality
