The invention discloses a seat radial damping mechanism and an automobile seat thereof.The seat radial damping mechanism comprises a step bolt, a framework connecting rod, a radial hydraulic damping sleeve, a supporting connecting rod and a gasket, the lower end of the framework connecting rod, the lower end of the supporting connecting rod and the gasket are each provided with a through hole, and a first lining is installed in the through hole of the framework connecting rod in a pressed mode; a second lining is pressed in a through hole of the supporting connecting rod, a step bolt sequentially penetrates through the first lining, the radial hydraulic damping sleeve, the second lining and the gasket in the transverse direction and is locked through a locknut, the step bolt is in interference fit with the radial hydraulic damping sleeve, and the second lining is connected between the step face of the step bolt and the gasket in an abutting mode. The upper end of the supporting connecting rod is fixedly connected with the framework connecting rod through a fastening bolt. Vibration energy generated in the vehicle driving process can be effectively absorbed and dispersed, the modal value of the seat is improved, seat shaking is reduced, and the NVH performance of the vehicle and the riding comfort of passengers are improved.

    本发明公开了一种座椅径向减震机构及其汽车座椅,座椅径向减震机构包括台阶螺栓、骨架连杆、径向液压减震套、支撑连杆和垫片,骨架连杆的下端、支撑连杆的下端和垫片上均设有贯穿孔,骨架连杆的贯穿孔中压装有第一衬套,支撑连杆的贯穿孔中压装有第二衬套,台阶螺栓沿横向依次穿过第一衬套、径向液压减震套、第二衬套和垫片,并通过防松螺母锁紧,台阶螺栓与径向液压减震套为过盈配合,第二衬套抵接于台阶螺栓的台阶面与垫片之间,支撑连杆的上端通过紧固螺栓与骨架连杆固定连接。本发明能有效吸收并分散车辆行驶过程中产生的震动能量,改善座椅模态值以及减小座椅抖动,提升车辆NVH性能和乘客乘坐舒适性。
