The invention discloses an automobile energy absorption box based on Jiyun origami and a structural design method of the automobile energy absorption box. The automobile energy absorption box comprises an energy absorption body and a flange plate. An energy-absorbing body of the designed energy-absorbing box is in a crease pattern of eight rows and eight columns of Jivillage origami, each folding unit in the pattern is composed of an isosceles trapezoid and an isosceles triangle, the short bottom edge of each isosceles trapezoid is a mountain fold, the long bottom edge of each isosceles trapezoid is a valley fold, the cross section of the energy-absorbing body formed by folding is a regular octagon, and the cross section of the energy-absorbing body is a triangular shape. And the flange plate is fixed through welding. When the energy-absorbing box is impacted, the energy-absorbing body crumples under the induction of the folding marks and is folded and deformed, so that the energy generated by the impact is absorbed. Compared with the design of a traditional energy absorption box, the folded paper structure has the function of the crumple groove, compression can be achieved to a larger extent, more energy is absorbed, and meanwhile the energy absorption box is simple in manufacturing process, low in cost and wide in applicability.
本发明公开了一种基于吉村折纸的汽车吸能盒及其结构设计方法,其包括吸能体和法兰盘。所设计吸能盒的吸能体利用了一个八行和八列的吉村折纸的折痕模式,该模式每一个折叠单元由一个等腰梯形和等腰三角形组成,其中等腰梯形的短底边为山折,长底边为谷折,折叠而成的吸能体横截面为正八边形,通过焊接与法兰盘固定。当该吸能盒受到撞击,吸能体在折痕的的诱导下溃缩,发生褶皱变形,从而吸收撞击产生的能量。本发明相较与传统的吸能盒设计,其折纸结构自带了溃缩槽的功能,可以实现更大程度的压缩,从而吸收更多能量,同时制作工艺简单,成本低,适用性广泛。
