The invention discloses an automobile body middle and rear floor structure and an automobile. The automobile body middle and rear floor structure comprises a left side longitudinal beam, a right side longitudinal beam, a left rear wheel cover, a right rear wheel cover, a front lower cross beam, a rear lower cross beam and a middle floor, the left side and the right side of the middle floor are connected with a left side longitudinal beam and a right side longitudinal beam respectively, the left rear wheel cover and the right rear wheel cover are correspondingly connected to connecting lines of the left side longitudinal beam and the right side longitudinal beam and the left side and the right side of the middle floor respectively, and the front end and the rear end of the middle floor are connected with a front lower cross beam and a rear lower cross beam respectively. Two ends of the front lower cross beam and two ends of the rear lower cross beam are respectively connected between the left longitudinal beam and the right longitudinal beam; the integrated die-casting all-aluminum structure is adopted, all middle and rear floors are achieved through one part, the part number and the connecting number are greatly reduced, and the material cost and the manufacturing cost of products are reduced; meanwhile, through reasonable structural setting, the requirements for the rear collision performance of the whole vehicle and the strength and rigidity of rear suspension installation are met.

    本发明公开了一种车身中后地板结构及汽车,包括一体压铸成型的左侧纵梁、右侧纵梁、左后轮罩、右后轮罩、前下横梁、后下横梁和中地板;所述中地板左右两侧分别连接有左侧纵梁和右侧纵梁,左后轮罩和右后轮罩分别对应连接于左侧纵梁和右侧纵梁与中地板左侧和右侧的连接线处,中地板前后端分别连接有前下横梁和后下横梁,且前下横梁两端和后下横梁两端分别连接于左侧纵梁和右侧纵梁之间;本发明采用一体压铸全铝结构,全部中后地板采用一个零件实现,极大的减少了零件数量和连接数量,降低了产品的材料成本和制造成本;同时,通过合理的结构设定,满足了整车后碰性能以及后悬架安装的强度和刚度要求。
