The invention relates to the field of vehicle engineering, and discloses a multi-pipe combined type energy absorption device based on a nested form and a vehicle, the energy absorption device comprises an anti-creeper 1, a plurality of nested type energy absorption pipes 2, a thin-wall shell 3 and a rear end plate 4, and the nested type energy absorption pipes 2 are fixed on the rear end plate 4; the rear end plate 4 is fixedly installed at the front end of a vehicle, the shell 3 is fixedly arranged on the periphery of the rear end plate 4 and surrounds the nested energy absorption pipe 2, the anti-creeper 1 is fixedly arranged at the other end of the shell 3, the nested energy absorption pipe 2 comprises an outer pipe 21 and an inner pipe 22 which are both provided with thin walls, the cross section of the inner pipe and the cross section of the outer pipe are both square, the outer pipe 21 protrudes outwards at a certain interval to form a reinforcing ring 23, and the outer pipe 21 protrudes outwards at a certain interval to form the reinforcing ring 23. And a plurality of folds 24 are preset on the inner pipe 21. According to the multi-pipe combined type energy absorption device based on the nested form and the vehicle, the energy absorption device is provided with the outer side reinforcing rings and the inner side pre-folded lines, so that the load fluctuation amplitude of a load curve is reduced while the energy absorption capacity of the structure is increased.

    本发明涉及车辆工程领域,其公开了一种基于嵌套形式的多管组合式吸能装置及车辆,该吸能装置包括防爬器1、多根嵌套式吸能管2、薄壁的外壳3和后端板4,嵌套式吸能管2固定在后端板4上;后端板4固定安装于车辆的前端,其四周固定设有外壳3,外壳3将嵌套式吸能管2包围,外壳3另一端固定设置防爬器1,嵌套式吸能管2包括均具有薄壁的外管21和内管22,内外管的横截面均为正方形,外管21间隔一段距离向外凸起,形成增强环23,内管21上预设多个折纹24。本发明提供的一种基于嵌套形式的多管组合式吸能装置及车辆,吸能装置具有外侧增强环和内侧预折纹的形式可使结构在吸能量增大的同时降低载荷曲线的载荷波动幅值。
