The side wall outer plate assembly structure comprises a side wall outer plate reinforcing plate assembly, a roof side rail outer plate and a rear wall outer plate, the side wall outer plate reinforcing plate assembly comprises a door ring, and the door ring is formed by welding a plurality of parts into a whole and used for being installed on one side, in the transverse direction, of a vehicle frame. The roof side rail outer plate is fixedly installed at the upper end of the side wall outer plate reinforcing plate assembly, the lower end of the roof side rail outer plate protrudes downwards along one transverse side, the roof side rail outer plate covers at least part of the upper end face of the side wall outer plate reinforcing plate assembly, and the rear wall outer plate is installed on one transverse side of the side wall outer plate reinforcing plate assembly. The upper end of the rear wall outer plate abuts against the lower end of the roof side rail outer plate along one longitudinal side and covers at least part of one transverse end face of the side wall outer plate reinforcing plate assembly. By means of the design, under the condition that the influence on the appearance and safety performance is small or even no influence exists, the large-scale light weight of the side wall outer plate assembly structure can be achieved, and the large-scale weight reduction of 9 kg of each trolley is achieved.
本发明公开一种侧围外板总成结构及汽车,包括侧围外板加强板总成、上边梁外板、以及后围外板,侧围外板加强板总成包括门环,门环由多个零件焊接为一体,用于安装在车架沿横向上的一侧,上边梁外板固定安装于侧围外板加强板总成的上端,上边梁外板的下端沿横向的一侧向下凸出设置,上边梁外板覆盖至少部分侧围外板加强板总成的上端面,后围外板安装于侧围外板加强板总成沿横向上的一侧,后围外板的上端与上边梁外板的下端沿纵向的一侧相抵接,且覆盖至少部分侧围外板加强板总成沿横向上的一端面。这样的设计能够在保证对外观、和安全性能影响较小甚至无影响的情况下,实现侧围外板总成结构的大幅度轻量化,达到了每台车9kg的大幅减重。
