The invention relates to an automobile A column assembly and an automobile, and relates to the technical field of white automobile bodies. The automobile A-pillar assembly comprises an A-pillar structure, a doorsill and a doorsill boundary beam. The A column structure comprises a side wall outer plate, an inner plate, a connecting plate and a reinforcing tubular beam. The inner plate is arranged on the inner side of the side wall outer plate, a cavity is formed between the side wall outer plate and the inner plate, and the connecting plate is arranged between the side wall outer plate and the inner plate. The reinforcing tubular beam is arranged in the cavity and is of a hollow columnar structure, and reinforcing ribs are arranged in the reinforcing tubular beam. The reinforcing tubular beam is connected with the connecting plate. And the reinforcing tubular beam and the doorsill are respectively connected with the doorsill boundary beam. Therefore, the structural strength of the A-column structure and the connecting strength of the A-column structure and the doorsill can be improved, and the possibility that the A-column assembly seriously deforms due to collision accidents is reduced; and meanwhile, the protection effect of the threshold on the battery is improved, and safety protection of the whole vehicle is improved.

    本申请涉及一种汽车A柱总成及汽车,涉及白车身技术领域。汽车A柱总成包括A柱结构、门槛和门槛边梁。其中,A柱结构包括侧围外板、内板、连接板和加强管梁。内板设于侧围外板的内侧,侧围外板与内板之间形成空腔,连接板设于侧围外板和内板之间。加强管梁设于空腔内,加强管梁为中空柱状结构,内部设有加强筋。加强管梁与连接板连接。加强管梁和门槛分别与门槛边梁连接。由此,可以提高A柱结构的结构强度,以及A柱结构与门槛的连接强度,减少A柱总成因碰撞事故出现严重变形的可能性;同时提升门槛对电池的防护效果,进而提升整车的安全防护。
