The light rear bumper framework comprises a long-strip-shaped framework body, the framework body comprises a top plate and a bottom plate which are horizontally arranged, the top plate and the bottom plate are oppositely arranged up and down, a middle pressure-resistant plate which is vertically arranged is connected between the top plate and the bottom plate, and the middle pressure-resistant plate, the top plate and the bottom plate extend in the same direction. The upper edge of the middle pressure-resistant plate is fixedly connected with the middle part of the top plate, and the lower edge of the middle pressure-resistant plate is fixedly connected with the bottom plate; an anti-impact plate is arranged on the front side of the middle pressure-resistant plate, the anti-impact plate is vertically connected with the middle pressure-resistant plate, a buffer deformation cavity is defined by the anti-impact plate, the middle pressure-resistant plate, the top plate and the bottom plate, and an opening of the buffer deformation cavity faces the front of the middle pressure-resistant plate. The invention has the following beneficial effects: the structural design is a thin-wall frame type structure, enough structural strength is provided, and the material consumption is controlled, so that the weight is reduced; in addition, the whole framework can be formed by conventional casting or die-casting, and is easy to produce.

    本发明公开了一种轻型后保险杠骨架,包括长条形的骨架本体,该骨架本体包括水平设置的顶板和底板,二者上下相对设置,二者之间连接有竖向设置的中间抗压板,该中间抗压板与所述顶板和底板同向延伸,该中间抗压板的上边缘与所述顶板的中部固定连接,下边缘与所述底板固定连接;所述中间抗压板的前侧设置有抗冲击板,所述抗冲击板垂直连接所述中间抗压板,所述抗冲击板与所述中间抗压板以及顶板和底板之间围成缓冲变形腔,该缓冲变形腔的开口朝向所述中间抗压板的正前方。本发明的有益效果是:结构设计为薄壁框架式结构,既提供足够的结构强度,又控制材料用量,从而降低重量;此外,整个骨架能够采用常规铸造或压铸成型,易于生产。
