Vehicle body rear floor structure and vehicle having the same

Abstract

The application provides a vehicle body rear floor structure and a vehicle. The vehicle body rear floor structure is integrally pressure-cast and has a rear floor body, rear floor longitudinal beams arranged on left and right sides, a rear floor cross beam connected between front ends of the rear floor longitudinal beams, door sill beam connecting portions protruding forward arranged at the front ends of the rear floor longitudinal beams, and longitudinal beam rear section connecting portions protruding rearward arranged at rear ends of the rear floor longitudinal beams. The door sill beam connecting portions are box-shaped structures with open bottoms, and each of the door sill beam connecting portions is provided with a first reinforcing rib. The door sill beam connecting portions and / or the longitudinal beam rear section connecting portions are provided with force transmission ribs connected with the rear floor longitudinal beams, and the force transmission ribs are arranged along the length direction of the vehicle body. The vehicle body rear floor structure can improve the torsional stiffness of the vehicle, make the force transmission path smoother, and improve the force transmission effect.
