The invention discloses an integrated rear floor structure and a body-in-white assembly with the same. Comprising a rear floor panel, rear floor longitudinal beams fixedly connected to the left side and the right side of the rear floor panel, rear wheel covers located on the left side and the right side of the rear floor panel and fixedly connected to the rear floor longitudinal beams, and a rear floor front cross beam fixedly connected between the front ends of the rear floor longitudinal beams. The rear floor panel, the rear floor longitudinal beam, the rear wheel covers and the rear floor front cross beam are of an integrally-formed structure, the front bottom face and the middle bottom face of the integrally-formed structure are respectively provided with a square-frame-shaped reinforcing rib structure and C-shaped reinforcing rib structures, the C-shaped reinforcing rib structures extend to the rear wheel covers on the left side and the right side from the rear floor panel, and a middle floor is fixed above the square-frame-shaped reinforcing rib structures. The designed rear floor structure is good in integration, excellent in lightweight performance, high in yield and good in collision performance, and the overall rigidity and torsion degree of a body in white are effectively improved.
本发明公开了一种一体化后地板结构及具有该结构的白车身总成,包括后地板面板、固定连接于后地板面板左右两侧的后地板纵梁、位于后地板面板左右两侧且固定连接于后地板纵梁上的后轮罩和固定连接于后地板纵梁前端之间的后地板前横梁;后地板面板、后地板纵梁、后轮罩和后地板前横梁为一体化成型结构,其前部底面和中部底面分别设置有方框型加强筋结构和由后地板面板延伸至左右两侧后轮罩上的C型加强筋结构,方框型加强筋结构的上方固定有中地板。本发明所设计的后地板结构集成性好、轻量化性能优、成品率高、碰撞性能好且有效提高了白车身的整体刚性和扭转度。
