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.
