The seat axial damping mechanism comprises a step bolt, an upper connecting support, an axial hydraulic damping sleeve, a damping fixing plate, a spring, a blocking piece and a locknut, the upper connecting support, the damping fixing plate and the blocking piece are each provided with a through hole allowing the step bolt to penetrate through, and a lining is installed in the through hole of the upper connecting support in a pressed mode; the step bolt sequentially penetrates through the lining, the axial hydraulic damping sleeve, the damping fixing plate, the blocking piece and the spring in the vertical direction and is locked through the locknut, the step bolt is in interference fit with the axial hydraulic damping sleeve, and the step face of the step bolt abuts against the upper surface of the blocking piece. 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轴向减震机构及其汽车座椅,包括台阶螺栓、上连接支架、轴向液压减震套、减震固定板、弹簧、挡片和防松螺母,上连接支架、减震固定板和挡片上均设有供台阶螺栓穿过的贯穿孔,上连接支架的贯穿孔中压装有衬套,台阶螺栓沿竖向依次穿过衬套、轴向液压减震套、减震固定板、挡片和弹簧,并通过防松螺母锁紧,台阶螺栓与轴向液压减震套为过盈配合,台阶螺栓的台阶面抵接于挡片的上表面上。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。
