The invention relates to the field of automobile manufacturing, in particular to an automobile rear inner wheel cover assembly structure. The automobile rear inner wheel cover assembly structure comprises an inner wheel cover body, a rear floor upper front beam and a rear floor upper rear beam; an inner wheel cover front upper reinforcing plate and an inner wheel cover rear upper reinforcing plateare arranged on the inner wheel cover body; an expansion plane is arranged on the inner wheel cover body; a rear wheel cover rear lower reinforcing plate is arranged on the expansion plane; one end of the inner wheel cover rear upper reinforcing plate extends to the expansion plane and is fixedly connected with one end of the rear wheel cover rear lower reinforcing plate; the other end of the rear wheel cover rear lower reinforcing plate is connected with the rear floor upper rear cross beam, the other end of the inner wheel cover rear upper reinforcing plate is connected to an automobile D column, and the inner wheel cover front upper reinforcing plate is connected with the rear floor upper front cross beam through the rear wheel cover front lower reinforcing plate. Under the condition that the space of a trunk is released to the maximum extent, the dynamic stiffness and the torsional stiffness are obviously improved, and it is guaranteed that force transmission of boarding and alighting bodies is smoother.

    本发明涉及汽车制造领域,尤其是涉及一种汽车后内轮罩总成结构。一种汽车后内轮罩总成结构,包括内轮罩本体、后地板上前横梁和后地板上后横梁,内轮罩本体上设置有内轮罩前上加强板和内轮罩后上加强板,内轮罩本体上设置有扩容平面,扩容平面上设置有后轮罩后下加强板,内轮罩后上加强板的一端延伸至扩容平面上并和后轮罩后下加强板的一端固定连接,后轮罩后下加强板的另一端与后地板上后横梁连接,内轮罩后上加强板的另一端连接在汽车D柱上,内轮罩前上加强板与后地板上前横梁之间通过后轮罩前下加强板连接。本发明能够在最大释放后备箱空间条件下,使动刚度、扭转刚度明显提升,保证了上下车体力传力更加顺畅。
