The invention provides a thermoforming jointed board B column structure, and belongs to the technical field of B columns, the thermoforming jointed board B column structure comprises an inner frame, a buffer assembly and a supporting assembly, the buffer assembly and the supporting assembly are arranged on the inner frame, the inner frame is close to an in-vehicle space, and an outer board is installed on one side of the inner frame. According to the invention, the arrangement of the honeycomb plate in the buffer assembly disperses stress and improves the overall bending strength through the deformation of the side wall of the honeycomb grid, and the internal cavity in the honeycomb plate is filled with air, so that the overall lightweight of the automobile is realized on the premise of ensuring that the B column has enough strength; hollow reinforcing ribs are arranged in the supporting assembly and are filled with air when the buffering assembly is compressed, the overall bearing capacity of the supporting assembly is improved, and meanwhile the light weight of the whole vehicle is further achieved through the hollow reinforcing ribs; when the buffering assembly and the supporting assembly fail, an air bag in the protection assembly expands to break the column B and expands towards the two sides, a soft buffering barrier is formed, and the situation that the head of a passenger directly collides with glass and is seriously injured is avoided.
本发明提供了一种热成型拼板B柱结构,属于B柱技术领域,包括内框和设置在内框上的缓冲组件和支撑组件,内框靠近车内空间,内框的一侧安装有外板。该发明,缓冲组件中蜂窝板的设置通过蜂窝格侧壁的变形来分散应力,提高整体的抗弯强度,蜂窝板中的内部空腔充满空气,在保证B柱具备足够强度的前提下,实现汽车整体的轻量化,支撑组件中空心加强筋的设置在缓冲组件被压缩时内部充满空气,提高支撑组件整体的承载能力,同时空心加强筋的设置进一步实现整车的轻量化,设置的防护组件在缓冲组件和支撑组件均失效时内部的气囊扩张顶破B柱并向两侧进行扩张,形成一道柔软的缓冲屏障,避免乘客头部直接撞击到玻璃上受到严重伤害。
