The invention discloses a vertical buffering device of an automobile seat. The device comprises a cushion, the right side of the cushion is movably connected with a backrest, a base is fixedly installed on the inner surface of the cushion, and the left side of the base is rotationally connected with an inclined rod. According to the vertical buffering device of the automobile seat, a first movable plate and a second movable plate are installed in the cushion, when an automobile rapidly falls down and makes contact with the ground, a short plate transmits elastic potential energy generated by pressure to the second movable plate, the elastic potential energy is converted into kinetic energy of the second movable plate, the kinetic energy continues to be transmitted, a part of the kinetic energy is transmitted to a buffering mechanism, the other part of energy which cannot be stored by the buffering mechanism is transmitted to the first movable plate through the buffering mechanism and converted into kinetic energy for movement of the first movable plate and the inclined rod, and the kinetic energy enables a supporting plate to generate elastic deformation at the same time. Through mutual conversion and absorption of potential energy and the kinetic energy, the pressure of the cushion on the seat is greatly reduced, and the problems that a traditional automobile seat is limited in energy absorption effect and poor in vertical protection performance are solved.
本发明公开一种汽车座椅垂向缓冲装置,包括坐垫,所述坐垫的右侧活动连接有靠背,所述坐垫内表面固定安装有底座,所述底座的左侧转动连接有斜杆。该汽车座椅垂向缓冲装置,通过在坐垫的内部安装一号活动板和二号活动板,当汽车急速下坠与地面接触时,短板将压力产生的弹性势能传递给二号活动板,弹性势能转化为二号活动板的动能,动能继续传递,一部分传递给缓冲机构,另一部分缓冲机构无法储存的能量由缓冲机构传递给一号活动板,转化为一号活动板和斜杆运动的动能,该动能同时又使得支撑板产生弹性形变,通过势能和动能的相互转化和吸收,大大减小了坐垫对座椅的压力,解决了传统汽车座椅吸能效果有限,垂向防护性能差的问题。
