Abstract

The invention provides a railway vehicle air supply, air return and roof integral structure which comprises a roof profile I, a roof profile II and a middle roof profile. The middle roof profile is a plate-shaped profile, the two sides of the middle roof profile are fixedly connected with the roof profile I and the roof profile II, a roof air inlet connected with an air conditioning unit is formed in the upper side of the middle roof profile, and the upper sides of the roof profile I and the roof profile II on the two sides of the roof air inlet are respectively provided with a roof air return port connected with an air conditioning unit; and a left air return cavity and a right air return cavity which protrude downwards are formed in the lower side of the roof profile I and the lower side of the roof profile II respectively, and a cavity defined by the left air return cavity, the right air return cavity and the built-in top plate forms an air supply cavity. The structure is small in occupied space, convenient to install, light in weight, high in strength and low in cost.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle manufacturing, and in particular relates to an overall structure of air supply, return air and roof of a rail vehicle. Background technique [0002] There are many parts on the roof of the rail vehicle, including the roof profile of the load-bearing structure, as well as separate air ducts, separate wire grooves, internal roof panels and beams, air supply grilles and other components, and the gap between these components and the roof profiles. Transition profile or mounting bracket. In previous rail vehicle projects, these components and the installation components between them and the roof profiles were all independent structures, with complex structures, large space occupation, heavy weight, complicated installation process, and high cost. Contents of the invention [0003] The present invention aims to solve the problems of traditional rail vehicle roof with complex structure, large spa...
