The invention belongs to the field of structural mechanics and anti-collision beams, and relates to an automobile anti-collision beam main beam which comprises a main beam body of a hollow structure, a plurality of unit cell structures are arranged in the main beam body, and each unit cell structure comprises two transverse ribs and two side ribs; the two transverse ribs are arranged in parallel, the two side ribs are located between the two transverse ribs and symmetrically connected to the two ends of the two transverse ribs, the two ends of one side rib are connected with the ends, in the same direction, of the two transverse ribs respectively, and the two ends of the other side rib are connected with the other ends of the two transverse ribs respectively; the two transverse ribs are square plates, the two side ribs comprise a first arc plate and two second arc plates, the two second arc plates are located at the two ends of the first arc plate respectively, and the two second arc plates are connected with the two transverse ribs. According to the structural design of the main beam of the anti-collision beam, when the main beam is impacted, the internal unit cell structure has larger deformation quantity when bearing pressure or pulling force, more energy can be absorbed, and the buffering capacity and the protection capacity of the main beam are improved.

    本发明属于结构力学、防撞梁领域,涉及一种汽车防撞梁主梁,包括中空结构的主梁,主梁内设有若干个单胞结构,单胞结构包括两个横肋和两个侧肋;两个横肋平行设置,两个侧肋位于两个横肋之间且对称连接于两个所述横肋的两端,其中一个侧肋的两端分别与两个横肋的相同方向的一端连接,另一个侧肋的两端分别与两个横肋的另一端连接;两个横肋均为方形板,两个侧肋均包括一个第一圆弧板和两个第二圆弧板,两个第二圆弧板分别位于第一圆弧板的两端,两个第二圆弧板与两个横肋连接。本发明本的防撞梁主梁结构设计使主梁在受到冲击时,内部的单胞结构承受压力或拉力时拥有更大的形变量,能够吸收更多的能量,提高主梁缓冲能力和防护能力。
