Processing method of electric heating composite floor, floor and railway vehicle provided with floor

Abstract

The invention provides a processing method of an electric heating composite floor, the floor and a railway vehicle provided with the floor. The electric heating composite floor comprises a bottom plate, a heating piece, a panel, a wire harness, a temperature control switch and a fuse, a wire groove is formed in the bottom plate, and the wire groove penetrates through one end of the bottom plate; the heating piece is attached to the bottom plate, and the panel is arranged on the side, where the heating piece is located, of the heating piece and attached to the bottom plate. N frames are defined by the heating pieces along the appearance of the bottom plate, n is a natural number larger than 1, and heating areas are formed in the frames; one end of the wiring harness extends into the wiring trough, and the extending tail end of the wiring harness is connected with the temperature control switch; the other end of the wire harness is positioned on the outer side of the bottom plate; the wire harness comprises a plurality of cables, and the cables are connected with the n heating pieces and provided with the fuses. The functional requirements of the bearing floor can be met, and electric heating can be achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a processing method of an electrically heated composite floor, a floor and a rail vehicle for installing the same. Background technique [0002] A load-bearing floor needs to be installed inside the rail vehicle, and the requirements for the floor are getting higher and higher. For example, if it is required to be soundproof, aluminum honeycomb floors are used. However, with the popularity of rail vehicles across the country and the operation in alpine regions, the floor is required not only to have heating functions, but also to be lightweight. [0003] The weight of the existing aluminum honeycomb floor does not meet the actual requirements of the whole vehicle. For example, the surface density of the aluminum honeycomb panel with the same thickness and specification is about 12kg / m2 (if the more inserts are embedded, the higher the unit plane weight) , In addition, the...

Problems solved by technology

[0003] The weight of the existing aluminum honeycomb floor cannot meet the maximum light weight required by the actual vehicle. For example, the surface density of the aluminum honeycomb panel with the same thickness specification is about 12kg / m2 (if the installation inserts are more pre-embedded, the weight per unit area will be higher) , In addition, the aluminum honeycomb panel cannot be combined with the heating sheet and wiring, and the floor heating cannot be realized, which cannot meet the design and use requirements
