The invention relates to the technical field of motor vehicles, in particular to an automobile rear supporting frame. The equipment includes an energy absorption seat, a plurality of buffer assemblies and a damping beam; wherein the multiple buffer assemblies are located on the side edges of the energy absorption base correspondingly; the buffer assembly comprises an outer spring, a connecting column, a sleeve and an inner spring; the outer spring is fixedly connected to the side edge of the energy absorption seat, the connecting column is fixedly connected to the side edge of the energy absorption seat, the sleeve is fixedly connected to the side edge of the outer spring, and the inner spring is arranged in the sleeve; and the damping beam is fixedly connected with the sleeves and located on the side edges of the sleeves. When rear-end collision of a rear vehicle occurs and the damping beam is impacted, the damping beam can push the sleeve to get close to the outer spring, and meanwhile, the sleeve can drive the inner spring to get close to the connecting column, so that through elastic potential energy of the outer spring and the inner spring, strong buffering effect can be provided when rear-end collision of the vehicle occurs, and vibration force borne by people in the vehicle is reduced; therefore, the passengers in the vehicle are prevented from injury.

    本发明涉及机动车技术领域,具体涉及一种汽车后支撑架;包括吸能座、多个缓冲组件和减震梁;多个缓冲组件分别位于吸能座侧边;缓冲组件包括外弹簧、连接柱、套筒和内弹簧;外弹簧固接于吸能座侧边,连接柱固接于吸能座侧边,套筒固接于外弹簧侧边,内弹簧设置在套筒内部;减震梁分别和多个套筒固定连接,并位于多个套筒侧边;当后方车辆发生追尾而对减震梁造成撞击时,减震梁会推动套筒靠近外弹簧,同时套筒会带动内弹簧靠近连接柱,通过外弹簧和内弹簧的弹性势能,可以在车辆发生追尾时提供良好的缓冲作用,降低车内人员受到的震动力,防止车内人员受伤。
