The invention discloses a body-in-white lightweight structure. The body-in-white lightweight structure comprises a side wall upper cross beam, wherein the side wall upper cross beam comprises a side wall outer upper cross beam and a rear wall inner upper cross beam, and the upper edge and the lower edge of the side wall outer upper cross beam and the upper edge and the lower edge of the rear wallinner upper cross beam are connected to form a closed cavity structure. According to the body-in-white lightweight structure, the beams are used as reinforcing structures, so that the area of parts issaved, and body-in-white lightweight is facilitated.

    本发明公开了一种白车身轻量化结构。它包括侧围上横梁,所述侧围上横梁包括侧围外上横梁和后围内上横梁,所述侧围外上横梁与后围内上横梁的上沿下沿分别连接形成封闭空腔结构。本发明将梁作为加强结构,节省零件面积,有利于白车身轻量化。
