The invention relates to the technical field of automobile body-in-white framework structures, and discloses an SUV rigidity improving structure and an automobile. A rear floor body is provided with a rear floor upper cross beam, and the two ends of the rear floor upper cross beam are connected with the two ends of a rear shock absorber upper cross beam above the rear floor upper cross beam through rear shock absorber connecting plates correspondingly to form a closed-loop supporting structure; the torsional rigidity and torsional mode of the body-in-white are improved; a V-shaped supporting plate is arranged between a rear floor upper cross beam and a rear shock absorber upper cross beam, the bent position of the bottom end of the V-shaped supporting plate is fixedly connected with the rear floor upper cross beam, and a rear shock absorber connecting plate and the end of a rear shock absorber upper cross beam body are connected into an integrated structure through the two ends of the V-shaped supporting plate. The V-shaped supporting plate is combined with the closed-loop supporting structure, so that a reasonable force path can be provided for the vehicle body, torsional deformation of the vehicle body is effectively restrained, the torsional rigidity and the torsional mode of the whole vehicle are improved, and the effect of reducing noise of the rear row of the whole vehicle is good.
本发明涉及汽车白车身骨架结构技术领域,公开了一种SUV刚度提升结构及汽车,后地板本体上设有后地板上横梁,后地板上横梁两端分别通过后减振器连接板与其上方的后减振器上横梁两端连接为闭环支撑结构,提升白车身扭转刚度和扭转模态;通过在后地板上横梁和后减振器上横梁之间设有V型支撑板,V型支撑板底端弯折处与后地板上横梁固定连接,两端将后减振器连接板和后减振器上横梁本体的端部连接为一体结构;V型支撑板的设置结合闭环支撑结构可以为车身提供合理的力的路径,有效的抑制车身扭转变形,从而提升整车的扭转刚度以及扭转模态,对降低整车后排噪声有很好效果。
