The invention discloses an energy absorption box inspired by the beak of a woodpecker. A unit body of an inner core comprises an anti-torsion round pipe and an anti-oblique-impact pipe; the anti-torsion round pipes are arranged in a square shape, and in the anti-torsion round pipes closest to the anti-oblique-impact pipe, a semicircular pipe is arranged in a gap between every two adjacent anti-torsion round pipes and the anti-oblique-impact pipe; the oblique impact resistant pipe is composed of an oblique connecting structure, a bird feather imitating three-axis plate and a bird feather imitating single-axis plate. The inclined edge of the inclined connecting structure is fixed to the outer side face of the bird feather imitating three-axis plate or the outer side face of the bird feather imitating single-axis plate. And each inclined connecting structure of the unit body I is embedded into the corresponding inclined connecting structure of the adjacent unit body II. The oblique connection structure of the oblique impact resistant pipe disperses the oblique impact force and reduces the axial impact force, and the bird feather imitating three-axis plate and the bird feather imitating single-axis plate have high elastic modulus, compressive strength and specific energy absorption; the anti-torsion pipe improves the anti-torsion capacity, and cooperates with the circular pipe and the semicircular pipe to trigger a high-order buckling mode, so that a higher energy absorption effect is achieved.
本发明公开了一种受啄木鸟鸟喙启发的吸能盒,内芯的单元体包括抗扭转圆管和抗斜向冲击管;多根抗扭转圆管排成方形,最靠近抗斜向冲击管的各抗扭转圆管中,每相邻两根抗扭转圆管与抗斜向冲击管的间隙中设置半圆管;抗斜向冲击管由倾斜连接结构、仿鸟羽毛三轴板和仿鸟羽毛单轴板组成;倾斜连接结构的倾斜边与仿鸟羽毛三轴板或仿鸟羽毛单轴板的外侧面固定;单元体一的各倾斜连接结构嵌入相邻单元体二对应倾斜连接结构内。本发明抗斜向冲击管的倾斜连接结构分散斜向冲击力,减少轴向冲击力,仿鸟羽毛三轴板和仿鸟羽毛单轴板具有高弹性模量、抗压强度和比吸能;抗扭转管提高抗扭转能力,与圆管和半圆管协同触发高阶屈曲模式,达到更高吸能效果。
