Specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

A kind of vehicle energy absorption box of efficient anticollision, referring to figs. 1 to 12, including shell 1, porous structure core 2 and composite fibre Pipe 3；The shell 1 and porous structure core 2 are six face cylinders；The upper bottom surface of the shell 1 and porous structure core 2 is just Rectangular, four seamed edges of the shell 1 and porous structure core 2 are distributed along the central axis central symmetry of the shell 1, and the rib Side is towards the curved curve of the central axis direction；The arcuate structure on pier shape square tube surface and 11 energy of oval defective hole thereon Play good inducing action.The porous structure core 2 is set to inside the shell 1；It is provided on the porous structure core 2 Multiple resigning roads 23, diagonal line distribution of the resigning road 23 along the porous structure core 2 for square of telling a story, the composite fibre pipe The 3 insertion resigning roads 23 are fixed.The porous structure core 2 is specifically by the spiral helicine honeycomb layer 21 of dagger-axe common vetch shape and three-dimensional point Battle array layer 22 is successively arranged alternately under upper；The transversal mask body of the honeycomb layer 21 is by multiple regular polygon basic units 211 are mutually spliced to form.
