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 compartm

Example Embodiment

[0030] Example one:

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

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

Example Embodiment

[0049] Embodiment two:

[0050] The difference from the first embodiment is that according to the requirements of the passenger compartment, the side roof 3 can not be additionally provided in the passenger compartment, and the middle roof structure can be directly used to realize the functions of air supply, return air, and lighting. The air processed by the air conditioning unit enters the supply air After the air duct 6 is inside, it flows out from the interior air outlets 13 on the side air supply plates 12 on both sides and enters the space on the side roof of the vehicle. The cold air is sent into the passenger compartment through natural convection to adjust the ambient temperature and humidity in the passenger compartment.

Example Embodiment

[0051] Embodiment three:

[0052] The difference from the above-mentioned embodiment is that, in addition to the side roof air supply openings 21 and 22 provided on the side roof 3, an in-vehicle air supply opening (not shown in the figure) can also be opened on the middle roof panel 2 according to actual needs. The air supply opening in the car on 2 can be composed of multiple small round through holes, or it can be a slit-shaped 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 ...
