The invention relates to a flexible connection structure for an auxiliary frame and a vehicle body. The flexible connection structure comprises a rear floor welding assembly and a flexible connection auxiliary frame, wherein the rear floor welding assembly is formed by connecting a rear floor panel assembly and a rear floor framework beam assembly; the flexible connection auxiliary frame is connected with the rear floor welding assembly; the flexible connection auxiliary frame is connected with the rear floor framework beam assembly through a connecting bolt; the rear floor framework beam assembly comprises two floor edge beams, a first rear cross beam and a second rear cross beam, wherein the first rear cross beam and the second rear cross beam are connected between the two floor edge beams. First rear cross beam connecting plates are respectively arranged at the connecting parts of the inner sides of the two floor edge beams and the two ends of the first rear cross beam to form two front mounting points, and second rear cross beam connecting plates are respectively arranged at the connecting parts of the inner sides of the two floor edge beams and the two ends of the second rear cross beam to form two rear mounting points; and rear axle mounting screw tubes are arranged on the front mounting point and the rear mounting point. The invention further relates to a vehicle with the flexible connection structure of the auxiliary frame and the vehicle body. The requirement for the dynamic stiffness of the connecting part of the auxiliary frame and the vehicle body can be met, and the comfort of a passenger compartment in the vehicle is improved.
