The invention belongs to the technical field of automobile safety driving, and particularly relates to a B stand column assembly structure which comprises an inner plate assembly and a reinforcer assembly, the inner plate assembly comprises an upper inner plate and a lower inner plate, the yield strength of the upper inner plate is larger than that of the lower inner plate, and the elongation of the upper inner plate is smaller than that of the lower inner plate; the reinforcing part assembly comprises a reinforcing plate and an anti-collision tubular beam fixedly installed on the reinforcing plate, the anti-collision tubular beam is columnar and located between the inner plate assembly and the reinforcing plate, and the reinforcing plate is fixedly connected with the inner plate assembly. The structure has the advantages that a columnar anti-collision tubular beam with a self-closed section structure is arranged in a B stand column assembly structure with a limited cavity size to replace a plurality of sheet-shaped reinforcing parts in a B stand column assembly cavity, and the structure is simple and reliable while a lap joint matching structure between parts in the B stand column assembly cavity is simplified and weight balance is optimized. And the side collision performance of the B stand column assembly can be greatly improved.

    本发明属于汽车安全行驶技术领域,具体涉及一种B立柱总成结构,包括内板总成和加强件总成,所述内板总成包括上内板和下内板,所述上内板的屈服强度大于下内板的屈服强度,所述上内板的延伸率小于下内板的延伸率,所述加强件总成包括加强板和固定安装在加强板上的防撞管梁,所述防撞管梁呈柱状,所述防撞管梁位于内板总成和加强板之间,所述加强板与内板总成固定连接。其目的是:通过在腔体尺寸有限的B立柱总成结构内部设置截面结构自封闭的柱状防撞管梁的方式,借以替代B立柱总成腔体内部的若干片状加强件,在对B立柱总成腔体内部零部件间的搭接匹配结构进行简化、重量平衡优化的同时,可大幅提升了B立柱总成的侧面碰撞性能。
