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.

    本发明涉及一种副车架与车身的软连接结构,由后地板面板总成和后地板骨架梁总成连接构成的后地板焊接总成,与后地板焊接总成连接的软连接副车架;软连接副车架通过连接螺栓与后地板骨架梁总成;后地板骨架梁总成包括两根地板边梁、连接在两根地板边梁之间的第一后横梁和第二后横梁;在两根地板边梁的内侧与第一后横梁两端的连接部位分别设有第一后横梁连接板,构成两个前安装点,在两根地板边梁的内侧与第二后横梁两端的连接部位分别设有第二后横梁连接板,构成两个后安装点,在前安装点和后安装点上均设有后桥安装螺管。还涉及具有该副车架与车身的软连接结构的车辆。其能够满足副车架与车身连接部位动刚度的要求,提高车内乘员舱的舒适性。
