The invention belongs to the field of automobile industry, and discloses a B column reinforcing plate structure, a B column using the same and a passenger vehicle. The B column reinforcing plate structure comprises a supporting column and a reinforcing supporting plate, the area, with the same height as the part needing to be protected by the passenger body, of the supporting column is locally thickened, and the reinforcing supporting plate is arranged. An induction weakening structure is arranged at the bottom of the supporting column, so that the whole component meets the requirement for light weight, the strength of key parts can be guaranteed, deformation can be generated through preset induction collapsing structures when collision occurs, collision energy is absorbed, passengers areprevented from being hurt, and the component can be applied to various passenger vehicles.
本发明属于汽车工业领域,公开了一种B柱加强板结构及使用该结构的B柱和乘用车。包括支撑柱、加强撑板,通过对支撑柱上与乘员身体需重点保护部位同高区域板材的局部加厚及设置加强撑板,并在支撑柱底部设置诱导弱化结构,使得整个构件既满足轻量化的要求,又能保证关键部位的强度,且在受到碰撞时能通过预设的诱导溃缩结构发生变形,吸收碰撞能量,避免乘员受到伤害,可应用于各类乘用车。
