Automobile roof lining structure

Abstract

The invention relates to an automobile roof lining structure which comprises a roof lining body and a plurality of mushroom hasps connected to the roof lining body in a positioning mode, the front edge of the roof lining body is in an arc shape, the rear edge of the roof lining body is straight, and the outline shape of the roof lining body is matched with that of a roof. A front ceiling lamp frame opening is formed in the front portion of the top cover lining body, a skylight frame opening and two side ceiling lamp frame openings are formed in the middle of the top cover lining body, and the two side ceiling lamp frame openings are located in the two sides of the skylight frame opening, the top cover lining body is of a layered structure and is composed of a base body layer, an adhesive layer, a sponge sound absorption layer and a decorative layer, the sponge sound absorption layer is adhered to one surface of the base body layer through the adhesive layer, and the decorative layer covers the sponge sound absorption layer; and a plurality of reinforcing ribs are arranged on the other surface of the base body layer. The plastic bracket is simple in composition structure, light in weight, high in strength, simple in forming process, low in mold cost and capable of saving raw materials, reducing cost and peculiar smell and overcoming the defect of appearance wrinkles caused by degumming and deformation of the plastic bracket.

Description

Technical field[0001]The present invention relates to an automotive body interior, and more particularly to a car top cover liner structure.Background technique[0002]The car roof lining is a soft member that is fitted to the top of the vehicle, mainly to the effect of decoration. The top cover liner is a component having a high value of heavier weight, and there is a large amount of space to reduce the weight and reduce costs. The traditional top cover is more complicated, including top cover liners 6, sunroof bracket 7, front head light bracket 8, two side top lamp holder 9 and multiple mushroom buckles 5, seefigure 1 . The conventional top cover liner 6 is a layered structure, and is composed of a fabric and a substrate. The fabric is overlapped by the surface layer 60, the sound absorbing layer 61, and the anti-infosite-free nonwoven fabric 62 three-layer material, and the substrate is from the first glass fiber layer 64, the PU plate 66, the second glass fiber layer 68 and the n...
