The invention discloses a recoverable and deformable energy-absorbing box for automobiles based on additive manufacturing, which comprises an upper end cover, a filling structure, a thin-walled shell, a mounting plate and a thin-walled corrugated
pipe, the bottom of the thin-walled shell is provided with a mounting plate, and the mounting plate There are several installation holes on the top, the filling structure is set inside the thin-walled shell, the thin-walled
bellows is set inside the filling structure, and the upper end cover is set on the top of the thin-walled shell; the thin-walled shell is detachable from the anti-collision beam of the car through the mounting holes The connection, filling structure, thin-walled shell and thin-walled
bellows are integrally printed and formed of high-entropy
alloy materials; the invention has excellent
energy absorption characteristics, and the filling structure proposed by the invention is a regular
hexahedron in which the four sides of the two opposite faces are respectively It is connected with four other unit
cell structures in different directions, which improves the
energy absorption while improving the
bearing capacity of the energy-absorbing box, so that it can maintain the stability and continuity of
energy absorption, high
bearing capacity, good stability, and can be reused. Reduce car maintenance costs.
