The invention discloses a B-pillar inner plate assembly structure of a frameless vehicle door, a vehicle body side wall and a vehicle, and relates to the technical field of vehicle body structures.The B-pillar inner plate assembly structure comprises an A-pillar roof side rail inner plate and a B-pillar inner plate body, and the rear end of the A-pillar roof side rail inner plate extends downwards to form a first connecting part with the preset length; the B column inner plate body extends upwards to form a second connecting part, the second connecting part is embedded into the first connecting part and connected with the first connecting part, and the bending depth of the two sides of the second connecting part is smaller than that of the two sides of the first connecting part; wherein the A-column roof side rail inner plate is made of a thermal forming material, and the B-column inner plate body is made of a cold punching material. The B-pillar upper structure is integrated on the A-pillar roof side rail inner plate which can be subjected to thermal forming processing, and the A-pillar roof side rail inner plate is provided with a deeper bending structure at the B-pillar upper part, so that the side impact performance of the B-pillar structure is ensured, and meanwhile, the B-pillar inner plate body is completely made of a cold punching material, so that the manufacturing cost is reduced.

    本发明公开了一种无框车门的B柱内板总成结构、车身侧围及车辆,涉及车身结构技术领域,包括:A柱上边梁内板和B柱内板本体,所述A柱上边梁内板在后端向下延伸出预设长度的第一连接部;所述B柱内板本体向上延伸出第二连接部,所述第二连接部嵌入所述第一连接部内并与所述第一连接部连接,所述第二连接部两侧的弯折深度小于所述第一连接部的两侧的弯折深度;其中,A柱上边梁内板采用热成型材料制成,B柱内板本体采用冷冲材料制成。本发明通过将B柱上部结构集成到可以热成型加工的A柱上边梁内板上,A柱上边梁内板在B柱上部处加工较深的弯折结构,满足保证B柱结构的侧碰性能,同时使得B柱内板本体完全采用冷冲材料制成,降低制造成本。
