The invention discloses an automotive insertion sheet filling type foamed aluminum energy absorption box. The automotive insertion sheet filling type foamed aluminum energy absorption box comprises an energy absorption box body, a rear mounting plate, an energy absorption body and inner foamed aluminum cores, wherein the energy absorption box body is fixedly connected with an automotive anti-collision beam, the rear mounting plate is fixedly connected with an automotive longitudinal beam, the energy absorption box body is connected with the rear mounting plate through the energy absorption body, and the inner foamed aluminum cores are arranged in an inner cavity of the energy absorption body; the energy absorption box body is a hollow box, N circles of parallel crumpling grooves are formed in the side wall of the energy absorption box body, N is larger than or equal to 1, and the crumpling grooves are perpendicular to the extrusion deformation direction of the energy absorption box body. When collision occurs, the crumpling grooves of the energy absorption box body induce the box body to deform and absorb energy in the circumferential direction, and stability of collision deformation is improved; static yield stress of the inner foamed aluminum cores is low, the stress platform stage is long and flat, and therefore overall energy absorption capacity and stability are greatly promoted; when the energy absorption box is assembled, the number of the inner cores can be determined by a buyer according to real automobile demands when the energy absorption box is assembled, the energy absorption capacity of the energy absorption box is improved, and the inner cores which do not deform can be recycled during collision accident maintenance.
