Combined passenger car roof interior layer

Abstract

The invention relates to a roof interior trim layer for a novel combined passenger car. The front end and the rear end of a roof fabric are respectively connected to end cross braces; the end cross braces are arranged at the front end and the rear end of the passenger car; in addition, two ends of the end cross braces are clamped with upper edges of corresponding luggage racks of the passenger car through buckles; one half of each zipper is arranged at each of the left and right sides of the roof fabric; the other half of each zipper is connected with a side connecting piece; each side connecting piece is inserted into a sliding chute reserved in the upper edge of the corresponding luggage rack of the passenger car. The invention designs a roof interior trim made of a weft knitting fabric; by using a spliced and combined framework, the weft knitting fabric is tightened on a roof framework of the passenger car and the luggage racks of the passenger car. The roof interior trim layer has the advantages of simple structure, convenience in use and mounting, attractiveness, elegance and low cost; the weight of the roof interior trim layer disclosed by the invention is only 30 to 50 percent that of a roof interior trim, produced by using an existing board, of the passenger car, and dead weight of the passenger car is greatly reduced, so that development requirements of light weight of the passenger car, energy conservation and emission reduction are met.

Description

Technical field: [0001] The invention relates to the technical field of passenger car ceiling structures, in particular to a novel combined passenger car ceiling interior layer. Background technique: [0002] At present, the bus roof is generally composed of three layers: exterior decoration layer, heat insulation layer and interior decoration layer. The interior decoration layer of the existing bus ceiling is mostly made of panels, mainly including PP honeycomb panels, flax panels, and aluminum-plastic panels. As well as the relatively low-end five-plywood bag fabrics, etc., the use of plates to make the interior structure of the bus roof needs to be fixed on the roof frame of the bus with fasteners. The fasteners generally use self-tapping screws. The bus roof interior made of plates The structure is complex, the cost is high, and the working environment of the workers is poor and the labor intensity is high during production and installation. At the same time, the panel ...

Problems solved by technology

[0002] At present, the bus roof is generally composed of three layers: exterior decoration layer, heat insulation layer and interior decoration layer. The interior decoration layer of the existing bus ceiling is mostly made of panels, mainly including PP honeycomb panels, flax panels, and aluminum-plastic panels. As well as the relatively low-end five-plywood bag fabrics, etc., the use of plates to make the interior structure of the bus roof needs to be fixed on the roof frame of the bus with fasteners. The fasteners generally use self-tapping screws. The bus roof interior made of plates The structure is complex and the cost is high. At the same time, the working environment of the workers is poor and the labor intensity is high during production and installation.

At the same time, the plate products are heavy, which is contrary to the existing lightweight development requirements of passenger cars
