Problems solved by technology
During the vehicle assembly process, both the floor bead and the electric heater need to be installed separately, and since the bottom of the electric heater is close to the floor, the installation is very inconvenient and the cost is high
[0003] In addition, the existing electric heaters are only suitable for use on rail vehicles operating on plains, but for rail vehicles operating in areas above 3600m above sea level, the temperature on the surface of the electric heating tube will increase by 20-30°C. The surface temperature of the cover plate will increase by 10-15°C, which will bring discomfort to the passengers sitting next to the electric heater, and if there are items placed on the electric heater, the items will be damaged, so the existing The electric heater in the technology cannot be applied to rail vehicles operating at high altitudes above 3600m

Embodiment Construction
[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0026] Such as Figure 1 to Figure 4 As shown, the electric heating device of a rail vehicle provided by the present invention is installed on the lower part of the side wall of the passenger compartment along the longitudinal direction of the car body. The heating component 2 and the cover plate 3 are fixed on the bottom plate component 1, and the bottom plate component 1 is fixed on the side wall 4 of the vehicle body.
[0027] Wherein, the bottom plate composition 1 is composed of a bottom plate 5 , a mounting plate 6 and a heat insulating material 7 . In order to reduce the weight, the mounting plate 6 is made of an aluminum plate, and the base plate 5 is made of a stainless steel plate to protect its installation strength.
[0028] Such as Figure 1 to Figure 3 As shown, the top of the mounting plate 6 has a U-shaped structure 9 with an ...

The invention relates to an electric heating device of a railway vehicle. The electric heating device comprises a bottom plate assembly, an electric heating assembly and a cover plate, wherein the electric heating assembly and the cover plate are fixed on the bottom plate assembly; and the bottom plate assembly comprises a bottom plate, a mounting plate and a thermal isolating material, the bottom plate is fixed on the mounting plate, the top of the mounting plate is fixedly connected with the side wall of a vehicle body, an extending part extending downwards is arranged at the bottom of the mounting plate, the tail end of the extending part is fixedly connected with a floor profile in a guest room, and the thermal insulating material is padded between the bottom plate and the mounting plate. The electric heating device is compact in integral structure, the bottom of the mounting plate is directly and fixedly connected with the floor profile in the guest room, a press plate at the bottom of the cover plate fixes the edge of floor cloth on the mounting plate, the cost is reduced, the mounting process is simplified simultaneously, and the production efficiency is improved substantially.
Description
technical field [0001] The invention relates to an electric heating device, in particular to an electric heating device for rail vehicles suitable for operation in alpine regions, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] At present, electric heaters for heating passengers in winter are installed in the body of most rail vehicles. Electric heating elements are installed in the electric heaters. The electric heating elements are fixed on the mounting plate, and the mounting plate is fixed on the side wall of the car body. , a cover plate is arranged on the outside, and an air inlet and an air outlet are opened on the cover plate. In the existing rail vehicle, the electric heater is installed at the lower part of the side wall of the car body, and its bottom is close to the floor, and in order to realize the transition between the floor profile and the side wall panel, it is necessary to set the floor bead at the edge of th...
