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.
