The invention belongs to the technical field of automobile safety driving, and particularly relates to a B column assembly structure capable of improving collision performance, the B column assembly structure comprises a B column inner plate and a B column anti-collision beam assembly, the B column anti-collision beam assembly comprises a split type reinforcing plate and a bent pipe beam, the split type reinforcing plate is fixedly installed on the pipe beam, and the bent pipe beam is fixedly installed on the B column inner plate. The split type reinforcing plate is fixedly connected with the B stand column inner plate, the yield strength of the split type reinforcing plate and the B stand column inner plate is smaller than that of the tubular beam, the elongation of the tubular beam is smaller than that of the split type reinforcing plate and the B stand column inner plate, and the yield strength of the upper portion of the split type reinforcing plate is larger than that of the lower portion of the split type reinforcing plate. The ductility of the upper portion of the split type reinforcing plate is smaller than that of the lower portion of the split type reinforcing plate. The invention aims to meet the requirements of the latest version of China New Vehicle Evaluation Regulation (C-NCAP) on the side collision performance and balance multiple indexes such as performance, weight, cost and the like.

    本发明属于汽车安全行驶技术领域,具体涉及一种可提升碰撞性能的B柱总成结构,包括B立柱内板和B立柱防撞梁总成,所述B立柱防撞梁总成包括分体式加强板和弯曲的管梁,所述分体式加强板固定安装在管梁上,所述分体式加强板与B立柱内板固定连接,所述分体式加强板和B立柱内板的屈服强度小于管梁的屈服强度,所述管梁的延伸率小于分体式加强板和B立柱内板的延伸率,所述分体式加强板上部的屈服强度大于分体式加强板下部的屈服强度,所述分体式加强板上部的延伸率小于分体式加强板下部的延伸率。其目的是:用来满足最新版本的中国新车评价规程(C‑NCAP)对侧面碰撞性能要求的同时,做到性能、重量、成本等多项指标的平衡。
