The invention discloses a design method of an automobile C-column structure and the automobile C-column structure, and relates to the technical field of automobile manufacturing, and the design method comprises the following steps: extending a C-column inner plate along the X direction of an automobile body, and integrally forming the C-column inner plate and a side window inner plate; the bottom of the C-column inner plate is connected with the rear wheel cover, and the top of the C-column inner plate is connected with the top cover; and the side, in the X positive direction of the automobile body, of the C-column inner plate is connected with the D-column structure, and the side, in the X negative direction of the automobile body, of the C-column inner plate is welded to the rear automobile door spigot. A conventional C column is combined with the side window inner plate, redundant C columns extend to the side window inner plate in the X direction and are integrally formed with the side window inner plate, and the integrated C column inner plate and the side window inner plate are a large piece, so that light weight of the C column inner plate is achieved, meanwhile, precision control during welding is improved, and the cost of a testing fixture is reduced.
本发明公开了一种汽车C柱结构的设计方法及汽车C柱结构,涉及汽车制造技术领域,其包括以下步骤:沿车身的X方向延长C柱内板,并将C柱内板和侧窗内板一体成型;将C柱内板的底部与后轮罩相连、C柱内板的顶部与顶盖相连;将C柱内板在车身的X正方向的一侧与D柱结构相连,将C柱内板在车身的X负方向的一侧与后车门止口焊接。本发明将常规的C柱与侧窗内板结合起来,将多余的C柱在X向延长至侧窗内板上,并与侧窗内板一体成型,一体式的C柱内板和侧窗内板是一个大件,这样使得C柱内板在实现轻量化的同时,提高了焊接时的精度控制,减少了检具的成本。
