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.

    本发明公开了一种阶梯式腔体铝合金材质汽车防撞梁主体结构,属于腔体铝合金防撞梁领域,包括主体结构、上腔体、中腔体、下右腔体、下左腔体、上加强脊、下右加强脊及下左加强脊,所述主体结构整体呈弧形,上顶面内侧起有一条加强脊,所述主体结构由上、中、下右、下左四个腔体组成,四个腔体呈阶梯式纵向排列,外表面凸出距离递减,所述上腔体宽度最大,外表面凸出在最外沿,率先承受冲击力,所述中腔体紧密连接在上腔体下部,所述中腔体外表面低于所述上腔体外表面,当上腔体外表面受力凹陷到一定距离后开始承受冲击力,所述下右腔体与所述下左腔体分别承受偏置方向冲击力。
