The invention discloses a thin-wall energy absorption device imitating white lotus vein distribution. The device comprises an energy absorption core, the energy absorption core comprises an outer thin-wall round pipe, an inner thin-wall round pipe, main vein rib plates and branch vein rib plates, the outer thin-wall round pipe and the inner thin-wall round pipe are coaxial, one ends of the main vein rib plates intersect at the axis of the inner thin-wall round pipe, the other ends are respectively arranged at intervals along the circumferential direction of the inner thin-wall round pipe, thebranch vein rib plates are arranged in a cavity inside the outer thin-wall round pipe and outside the inner thin-wall round pipe, and the branch vein rib plates are uniformly distributed on the two sides of the main vein rib plate. The branch vein rib plates and the adjacent branch vein rib plates are intersected on the inner surface of the outer thin-wall circular pipe or the outer surface of theouter thin-wall circular pipe. The number of the main vein rib plates is 4-7. According to the invention, the total energy absorption can be enhanced, the specific energy absorption and load efficiency is higher, the passive safety of an automobile is greatly improved, and casualties are reduced; and the whole body is made of aluminum or an aluminum alloy material, so that the weight can be greatly reduced, and the light weight of the automobile can be better met.
本发明公开了一种仿玉莲叶脉分布的薄壁吸能装置,包括吸能芯,吸能芯包括外薄壁圆管、内薄壁圆管、主叶脉筋板和分枝叶脉筋板,外薄壁圆管与内薄壁圆管同轴,主叶脉筋板的一端相交于内薄壁圆管的轴心处,另一端分别沿内薄壁圆管的周向均匀间隔设置,分枝叶脉筋板设置在外薄壁圆管内、内薄壁圆管外的空腔内,分枝叶脉筋板在主叶脉筋板的两侧均匀分布。分枝叶脉筋板与其相邻分枝叶脉筋板相交于外薄壁圆管内表面或者外薄壁圆管外表面。主叶脉筋板数量为4~7个。本发明能够增强吸收总能量,具有更高的比吸能和载荷效率,大大提高了汽车的被动安全性,减低人员伤亡;整体均由铝或铝合金材料制成,能够大幅度降低重量,进而较好地满足汽车的轻量化。
