Seat suspension damp adjusting method and seat suspension

Abstract

The invention relates to a seat suspension damp adjusting method and a seat suspension. The seat suspension comprises a fixed substrate, a seat mounting plate, a shear-type support, an electromagnetic force generator, a detector, an adjustable resistor and a processor; the seat mounting plate is connected with the fixed substrate through the shear-type support in a floating manner, the electromagnetic force generator is connected with the shear-type support, the detector detects displacement and / or accelerated speed of the seat mounting plate, the adjustable resistor and the electromagnetic force generator are serially connected to form an electrical connection circuit, the processor is electrically connected with the adjustable resistor and the detector to form a control circuit, the processor calculates target resistance of the adjustable resistor according to the displacement and / or accelerated speed, resistance of the adjustable resistor is equal to the target resistance, and inverse electromagnetic moment output by the electromagnetic force generator is then adjusted. By the arrangement, use of a magneto-rheological fluid damper is avoided, sealing of operating fluid is not needed, and damp of the seat suspension can be adjusted in real time.

Description

technical field [0001] The present application relates to the technical field of motor vehicles, in particular to a method for adjusting seat suspension damping and the seat suspension. Background technique [0002] When a driver drives a motor vehicle, the performance of the seat suspension directly affects the comfort of the driver. For motor vehicles, especially heavy-duty engineering vehicles, agricultural vehicles, mining vehicles, etc., the severe vibration caused by the uneven road surface will be directly transmitted to the occupants, which seriously affects the comfort of the occupants. Safety and ease of operation can even cause various health problems, such as shoulder discomfort, back pain, etc. [0003] Seat suspension can be mainly divided into three types: passive seat suspension, semi-active seat suspension and active seat suspension. At present, the traditional semi-active seat suspension mainly uses dampers such as magnetorheological fluid or electrorheol...

AI Technical Summary

Problems solved by technology

[0004] However, there are still a series of problems in the practical application of the scheme using the magnetorheological fluid damper. For example, the magnetorheological fluid is the working fluid of the damper, so the sealing problem of the working fluid needs to be considered

For the magnetorheological fluid damper, it has high requirements on sealing performance. If there is a problem with the sealing, it will directly lead to the failure of the magnetorheological fluid damper.
