The invention discloses an integrated high-strength automobile rear floor frame structure and assembly. The rear floor frame structure comprises a left longitudinal beam module and a right longitudinal beam module. Four parallel cross beams, namely a first cross beam module, a second cross beam module, a third cross beam module and a fourth cross beam module, are sequentially connected between the left longitudinal beam module and the right longitudinal beam module; transition areas are arranged at the joints between the left longitudinal beam module and the first cross beam module, between the right longitudinal beam module and the second cross beam module, between the right longitudinal beam module and the third cross beam module and between the right longitudinal beam module and the fourth cross beam module; wherein the four cross beams are aligned with the parting positions of the left longitudinal beam module and the right longitudinal beam module in the X direction. According to the method, the development cost is effectively reduced, the development period is shortened, and the tool cost investment is reduced. The strength is guaranteed, the sealing performance is improved, the precision is improved, and the universal rate is improved. And the expandability, the flexibility and the assembly efficiency of the platform are improved.

    本发明公开了一种一体式高强度汽车后地板框架结构及总成,后地板框架结构包括左纵梁模块和右纵梁模块;左纵梁模块和右纵梁模块之间依次连接有平行的四个横梁:第一横梁模块、第二横梁模块、第三横梁模块以及第四横梁模块;左纵梁模块和右纵梁模块分别与第一横梁模块、第二横梁模块、第三横梁模块以及第四横梁模块的连接处均设有过渡区域,过渡区域上设有R角;其中四个横梁与左纵梁模块和右纵梁模块的分缝位置在X向位置保持对齐。本发明有效降低了开发成本,节约开发周期和减小工装成本投入。保证了强度,提升了密封性能,提升了精度,提升通用率。且提高平台可拓展度、灵活度,及装配效率。
