The invention discloses a stepped cavity aluminum alloy automobile anti-collision beam main body structure, which belongs to the field of cavity aluminum alloy anti-collision beams, and comprises a main body structure, an upper cavity, a middle cavity, a lower right cavity, a lower left cavity, an upper reinforcing ridge, a lower right reinforcing ridge and a lower left reinforcing ridge, the body structure is integrally arc-shaped; and the inner side of the upper top surface is provided with a reinforcing ridge; wherein the main body structure is composed of an upper cavity, a middle cavity, a lower right cavity and a lower left cavity, the four cavities are longitudinally arranged in a stepped mode, the protruding distance of the outer surfaces of the four cavities is decreased progressively, the width of the upper cavity is the largest, the outer surface of the upper cavity protrudes out of the outermost edge and bears impact force firstly, and the middle cavity is tightly connected to the lower portion of the upper cavity. The outer surface of the middle cavity is lower than the outer surface of the upper cavity. And when the outer surface of the upper cavity is stressed and sunken to a certain distance, the upper cavity begins to bear the impact force, and the lower right cavity and the lower left cavity bear the impact force in the offset direction respectively.
