The invention provides an automobile collision
energy absorbing box capable of achieving high-efficiency and stable
energy absorption. The automobile collision
energy absorbing box comprises flanges,a square thin-walled outer shell, lattice structures and a sandwich plate; the flanges are arranged at the upper and lower ends of the square thin-walled outer shell, the lattice structures are arranged on the upper and lower ends of the sandwich plate, and the lattice structures and the sandwich plate are integrally arranged in the square thin-walled outer shell; each lattice structure is formedby distributing aluminum tubes according to the body square
diagonal; the sandwich plate comprises two
layers of carbon
fiber sheets and a
honeycomb structure arranged between the two
layers of carbonfiber sheets; the
honeycomb structure is formed by staggered distribution of regular octagons and regular squares; the lattice structures and the sandwich plate are connected into a whole through
spot welding, and the square thin-walled outer shell and the flanges are connected into a whole through
spot welding; and the flanges are connected and fixed to a
transverse beam and a longitudinal beamof an automobile through bolts. The automobile collision
energy absorbing box solves the problems that a traditional energy absorbing box is unstable in
energy absorption, poor in multi-angle
impact adaptability, discontinuous, low in efficiency and the like.
