Problems solved by technology

Moreover, both the middle roof and the side roof are fixedly installed at the bottom of the air duct on the roof, and the installation of the middle roof depends on the structure of the air duct and requires vehicle assembly site construction
[0004] In addition, some rail vehicles are limited by the vehicle boundary. Under the premise of ensuring the interior height space of the passenger compartment, there is not enough space above the ceiling in the passenger compartment to arrange air-conditioning air ducts.
However, the air supply duct in the prior art not only increases the overall height of the vehicle, cannot meet the limit requirements of the vehicle height, but also occupies a large roof space.
At the same time, it also makes the structure of the middle roof of the vehicle complex, increases the cost, and indirectly increases the weight of the vehicle body, which cannot meet the requirements of light weight of the vehicle body

Embodiment 1

[0031] Such as figure 1 As shown, the present invention provides a rail vehicle, including a car body, a roof-mounted air-conditioning unit, a waste discharge device, etc., and the roof-mounted air-conditioning unit is fixedly installed on the roof steel structure 1 at the top of the car body. An interior trim panel is installed on the inner side of the car body to beautify the riding environment in the passenger compartment. The interior trim panel includes a side wall panel 23, a middle roof panel 2 in the middle of the roof, side roof panels 3 on both sides of the roof, end wall panels and Floor, wherein side top board 3 is two, is installed in the both sides of middle top board 2. In this embodiment, the middle roof plate 2 is fixedly installed on the roof steel structure 1 as a whole as a modular structure.

[0032] Such as figure 1 and figure 2 As shown, the middle roof modular structure provided by the present invention includes a middle roof 2 in the middle of the ...

Embodiment 2

[0050] The difference from Embodiment 1 is that according to the requirements of the passenger room, no side roof 3 is provided in the passenger room, and the middle roof structure is directly used to realize functions such as air supply, return air, and lighting, and the air treated by the air conditioning unit enters the air supply After the air duct 6, it flows out from the air supply port 13 in the car on the side air supply plate 12 on both sides, and enters the space on the side roof of the vehicle, and cold air is sent into the passenger room by natural convection to regulate the ambient temperature and humidity in the passenger room.

Embodiment 3

[0052] The difference from the above embodiment is that, in addition to setting the side roof air outlets 21 and 22 on the side roof 3, the interior air outlets (not shown) can also be set on the middle roof 2 according to actual needs. The air supply port in the car on 2 can be made up of a plurality of small round through holes, also can be the slit shape opening.

Abstract

The invention relates to a middle roof modular structure and a railway vehicle. The middle roof modular structure comprises a middle roof plate. The two sides of the middle roof plate are fixedly provided with lamp belts, hanging beams are fixedly arranged on the positions above the lamp belts, the middle roof plate, the lamp belts and the hanging beams are of a U-shaped structure as a whole and hung on a vehicle roof steel structure. According to the middle roof modular structure and the railway vehicle, the middle roof plate, the lamp belts and an air flue inner cavity are integrated to form the modular structure, the modular structure is high in modular degree, the assembling efficiency can be improved greatly, and the production cost is lowered.

Description

technical field [0001] The invention relates to a rail vehicle, in particular to a rail vehicle mid-roof modular structure, and at the same time relates to a rail vehicle equipped with the modular structure, belonging to the technical field of rail vehicle manufacturing. Background technique [0002] In rail vehicles, each passenger compartment is generally equipped with one or two air-conditioning units, and each air-conditioning unit adopts a unitary structure, and the whole air-conditioning unit is arranged at the bottom of the car body or on the roof. The air conditioner unit is connected to the air supply port and the return air port in the car through the air supply duct and the return air duct. It enters the air conditioning unit through the air return port, mixes with the fresh air, and then exchanges heat with the evaporator to complete the refrigeration cycle. [0003] Rail vehicles in the prior art generally install an air supply duct connected to the air supply ...
