Abstract
The invention provides a new-style tonneau cover, wherein comprises a cover plate body matching the rear truck bed. The cover plate body is a three-layer structure, comprising an outer layer, an intermediate layer and an inner layer from the exterior to the interior. The outer layer is made of polyurethane foam mixed with glass fiber; the intermediate layer is made of polyurethane foam and the inner layer is made of resin; the density of polyurethane foam in the intermediate layer is lower than that in the outer layer; polyurethane foam is light in weight and high in specific strength. In this invention, the cover plate body is made of three different layers so that the cover is light in weight and high in strength, taking up less room of the rear truck bed, better for free opening and closing operation.
