The invention discloses a rear wall plate assembly structure and an automobile. The rear wall plate assembly structure comprises a rear wall outer plate and a rear wall inner plate. The rear wall outer plate comprises a vertical section and an inclined section; the vertical section comprises a first end and a second end; the inclined section comprises a third end and a fourth end; the first end isconnected with the third end; the distance between the projection of the second end in the vertical direction and the projection of the fourth end in the vertical direction ranges from 144 mm to 224mm. The distance between the projection of the second end in the horizontal direction and the projection of the fourth end in the horizontal direction ranges from 333 mm to 413 mm. The invention further discloses an automobile applying the rear wall plate assembly structure. According to the rear wall plate assembly structure, under the condition that the cross section of the rear wall is heightened and enlarged in the X direction and the Z direction, the good torsional rigidity of a vehicle body and the rigidity of a tail door lock catch fixing point can be guaranteed, abnormal sounds and safety risks are prevented, platformization of a lower vehicle body is supported and achieved, and the manufacturing cost and the research and development cost are reduced.

    本发明公开了一种后围板总成结构及汽车,包括后围外板和后围内板;所述后围外板包括竖直段和倾斜段;所述竖直段包括第一端和第二端;所述倾斜段包括第三端和第四端;所述第一端和所述第三端连接;所述第二端在竖直方向上的投影和所述第四端在竖直方向上的投影之间的距离为144毫米至224毫米;所述第二端在水平方向上的投影和所述第四端在水平方向上的投影之间的距离为333毫米至413毫米。本发明还公开了一种汽车,应用了上述后围板总成结构。本发明涉及的后围板总成结构能够在后围断面X向、Z向变高变大的情况下保证车身较好的扭转刚度及尾门锁扣固定点刚度,防止异响和安全风险,而且也支持和实现了下车身平台化、降低制造成本研发成本。
