Nonlinear shock-absorbing suspension of car seat

Abstract

The invention relates to a nonlinear shock-absorbing suspension of a car seat, wherein two symmetrical slideways are respectively arranged at the lower end face of a seat faceplate and the upper end face of a lower bottom plate; one end of a shear bar I is hinged with the seat faceplate; the other end of the shear bar I is connected with a slide bar I in the slideway arranged at the upper end face of the lower bottom plate; one end of a shear bar II is hinged with the lower bottom plate; the other end of the shear bar II is connected with a slide bar II in the slideway arranged at the lower end face of the seat faceplate; a guide supporting wheel is arranged at the upper end face of the lower bottom plate; one end of a shock-absorbing supporting bar is fixedly connected with the upper end face of a shock-absorbing curved plate; the other end of the shock-absorbing supporting bar is connected with the upper end of the shear bar I through a rotating shaft; the lower end face of the shock-absorbing curved plate is an internally concave curved surface; the lower end face of the shock-absorbing curved plate presses on the guide supporting wheel; a torsional spring is arranged on the rotating shaft; one end of the torsional spring is connected with the shear bar I; and the other end of the torsional spring is connected with the shock-absorbing supporting bar. The suspension is simple in structure and convenient for adjustment; the vibration isolating capability of cars is averagely increased by more than 40%; and the increasing range is larger when the car speed is higher.

Description

technical field [0001] The invention relates to a shock absorbing device for a vehicle driver's seat, in particular to a non-linear shock absorbing suspension for a vehicle seat. Background technique [0002] When the vehicle is running, it is excited by the force between the tire and the ground to generate strong shock and vibration. Studies have shown that the driver is exposed to low-frequency, large-amplitude vibration for a long time, causing muscle and nerve tension, increased cardiopulmonary activity, and gastrointestinal discomfort. Over time, obvious physiological degeneration and occupational diseases appear, such as spinal hyperplasia, deformity and strain, neurasthenia, vision loss, joint pain, gastrointestinal bleeding, etc. In recent decades, research on ride vibration related to occupant health has been paid more and more attention. [0003] The magnitude of vehicle ride vibration depends on the structure and parameters of its tires, suspension and seats. Im...

AI Technical Summary

Problems solved by technology

Domestic seat manufacturers are generally small in scale and basically have no development capabilities. Most of the seat products have unreasonable structural dimensions and incomplete adjustment mechanisms. The dynamic comfort of the seat exceeds the standard, and the static comfort of the seat is also poor.
