The invention discloses a frameless door automobile B column side collision structure, which comprises a B column reinforcing plate and a B column inner plate, a closed cavity structure is defined by the B column reinforcing plate and the B column inner plate, a B column supporting plate and a B column supporting sealing plate are arranged in the closed cavity structure, the B column supporting plate and the B column reinforcing plate are fixed, an inner closed cavity is defined by the B column supporting plate and the B column supporting sealing plate, and the closed cavity structure and the inner closed cavity form a hollow-square-shaped cavity. According to the automobile B-pillar side collision structure with the frameless door, the B-pillar supporting plate and the B-pillar supporting sealing plate are additionally arranged, the whole B-pillar upper structure is a hollow-square-shaped cavity, and the double cavities absorb collision energy, so that the deformation resistance is greatly improved.
本发明公开了一种无框车门汽车B柱侧碰结构,包括B柱加强板和B柱内板,B柱加强板和B柱内板围成闭合空腔结构,闭合空腔结构内设有B柱支撑板和B柱支撑封板,B柱支撑板与B柱加强板固定,B柱支撑板与B柱支撑封板围成内封闭空腔,闭合空腔结构和内封闭空腔形成回字形腔体。本发明提供了一种无框车门汽车B柱侧碰结构,增加B柱支撑板及B柱支撑封板,整体B柱上部结构呈现为回字形腔体,双重腔体吸收碰撞能量,从而大大提高抗变形能力。
