The invention relates to a novel pre-folded thin-wall collision energy-absorbing box which comprises an energy-absorbing box unit cell, the energy-absorbing box unit cell comprises an upper portion and a lower portion which are folded and symmetrical about the horizontal center line, and each of the upper portion and the lower portion comprises two trapezoidal plates, two parallelogram plates and two triangular plates. The trapezoid plates, the parallelogram plates and the triangular plates are sequentially staggered to define an irregular box type energy absorption box unit cell with the periphery closed and the upper and lower openings, and the upper opening, the central fold line and the lower opening of the energy absorption box unit cell are parallel to one another. The automobile energy absorption box is ingenious in design, simple in structure, scientific and reasonable, the defects that a traditional energy absorption box is unstable in energy absorption and low in energy absorption efficiency are overcome, energy is continuously and efficiently absorbed, stability is high, protection on pedestrians and passengers in an automobile during collision is improved, and life and property safety of people is effectively guaranteed. Good market prospects and development space are realized.

    本发明涉及一种新型预折叠薄壁碰撞吸能盒,包括吸能盒单胞,吸能盒单胞包括关于水平中线折叠对称的上部、下部,所述上部、下部均包括两个梯形板、两个平行四边形板和两个三角形板,梯形板、平行四边形板和三角形板依次交错围成一个四周封闭、上下开口的不规则箱体式吸能盒单胞,其中,吸能盒单胞的上开口、中心折线和下开口相互平行。本发明设计巧妙,结构简单,科学合理,克服传统吸能盒吸能不稳定、吸能效率低缺点,持续高效率吸能且稳定性较高的汽车吸能盒,以提高碰撞时对行人和车内乘员的保护,有效保障人们生命及财产安全,对现有技术来说,具有很好的市场前景和发展空间。
