The collision buffering and energy absorbing device capable of being folded and stored comprises a supporting structure and a collision buffering assembly, the supporting structure comprises a bottom plate, a top plate and supporting connecting rods, the four corners of the bottom plate and the four corners of the top plate are connected through the supporting connecting rods respectively, and each supporting connecting rod comprises an upper connecting rod, a lower connecting rod and a rotating pair; the axes of the revolute pairs in each supporting connecting rod are arranged in parallel; the collision buffering assembly is installed in the supporting structure and does not interfere with the supporting connecting rods, when the device bears pressure, the supporting structure is folded under the pressure effect, and in the folding process, the collision buffering assembly is pressed to deform to absorb collision energy, and the buffering effect is achieved. On the basis that the defects that a traditional collision buffering material is low in longitudinal rigidity and prone to instability when the collision stroke is too long are overcome, the air bag is adopted as the collision buffering material, the weight of the device is effectively reduced, the device can be folded and stored in the storage state, and the occupied space is small in the storage state.

    本发明公开了一种可折叠收纳的碰撞缓冲吸能装置,包括支撑结构和碰撞缓冲组件,所述支撑结构包括底板、顶板和支撑连杆,所述底板与顶板之间在四角处各通过一条支撑连杆连接,所述支撑连杆包括上连杆、下连杆以及转动副,每条支撑连杆中各转动副轴线平行设置;所述碰撞缓冲组件安装于支撑结构内部且与各支撑连杆互不干涉,装置承压时,支撑结构在压力作用下收拢,收拢过程中,碰撞缓冲组件受压变形吸收碰撞能量,起到缓冲作用。本发明装置在克服传统碰撞缓冲材料纵向刚度低,碰撞行程过长时材料容易失稳缺陷的基础上,采用气囊作为碰撞缓冲材料,有效减轻了装置重量,且在储存状态时可进行折叠收纳,收纳状态下所占空间小。
