The invention relates to an automobile B column reinforcing structure and an automobile B column. The automobile B column reinforcing structure comprises a B column reinforcing plate, a B column roof side rail and a plurality of first supporting plates, and the B column roof side rail is connected to the top of the B column reinforcing plate; and the first supporting plates are assembled in a cavity of the B column roof side rail, and the first supporting plates, the B column roof side rail and the B column reinforcing plate jointly form a triangular stable structure used for increasing the top pressure value of a vehicle body in the connecting area of the B column roof side rail and the B column reinforcing plate. The first supporting plates can support a cavity of the B column roof side rail, so that the B column roof side rail is prevented from collapsing and deforming under the action force of collision, and the supporting strength of the B column roof side rail is enhanced; and the triangular stable structure can improve the overall strength and rigidity of the joint and the peripheral area of the B column reinforcing plate and the B column roof side rail, stress concentration deformation is prevented from being formed in the joint and the peripheral area, and therefore the jacking performance of the whole automobile body is improved, and the safety of passengers is improved.

    本申请涉及一种汽车B柱加强结构及汽车B柱,汽车B柱加强结构包括B柱加强板、B柱上边梁和若干第一支撑板,B柱上边梁连接于B柱加强板的顶部;第一支撑板组设于所述B柱上边梁的腔体内,且各所述第一支撑板、所述B柱上边梁与所述B柱加强板共同在所述B柱上边梁与所述B柱加强板相连接区域形成有用于提升车身顶压值的三角形稳定结构。第一支撑板可以对B柱上边梁的腔体进行支撑,从而防止在碰撞作用力下,B柱上边梁发生溃缩变形,以此增强B柱上边梁的支撑强度;三角形稳定结构可以对B柱加强板与B柱上边梁接头及周边区域的整体强度和刚度进行提升,避免在接头及周边区域形成应力集中变形,从而提升整个车身顶压性能,提升乘员安全性。
