Installation structure of rail vehicle, car body and blind window

Abstract

The invention discloses a railway vehicle, a vehicle body and a blind window installation structure. The blind window installation structure is used for installing blind windows on the vehicle body. The vehicle body is provided with grooves used for installing the blind windows, the depth of the grooves is equal to the thickness of the blind windows, and therefore the blind windows are parallel and level to the vehicle body after the blind windows are installed into the grooves. The blind windows are connected into the grooves through bolts and nuts. The vehicle body is provided with sliding chutes, the opening width of the sliding chutes is larger than the screw diameter of the bolts and smaller than the external diameter of the nuts, and the sliding chutes are provided with inlets allowing the bolts and the nuts to enter the sliding chutes. By adopting the blind window installation structure, the installation process of the blind windows is simple, fast and convenient, meanwhile, noise generated during high-speed operation of the vehicle can be effectively reduced, and beauty can be obtained after the blind windows are installed on the vehicle body.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle, a vehicle body and a blind window installation structure. Background technique [0002] With the rapid development of regional economy and the rapid rise of urban agglomerations, more and more people are busy running between different cities, which requires a convenient, fast, safe and reliable means of transportation to meet people's growing travel needs , the intercity EMU came into being. Intercity EMUs have the advantages of fast start and stop, fast boarding and landing, large passenger capacity, and low cost, and are more and more popular among people. [0003] At present, the speed of domestic intercity EMUs has reached 200 kilometers per hour, and the high-speed operation of rail vehicles will inevitably lead to design requirements that take into account both the rigidity of the car body and the lightweight structure. The high-speed rail vehicle in...

Problems solved by technology

[0004] However, in the prior art, any adjacent two windows on each car body are spaced apart by the car body, the windows are discontinuous, and there is no smooth transition between the windows and the car body, resulting in high-speed trains. When running, the aerodynamic performance is reduced, and air flow is generated locally, which in turn increases the noise in the car

[0005] In addition, in the prior art, the windows on each car body are installed separately one by one, which is time-consuming and labor-intensive to install, and the installation is inconvenient, and because the windows are separated one by one, the aesthetics is poor

[0006] Therefore, how to solve the problems of high noise and time-consuming and labor-consuming installation of rail vehicles due to the limitation of window installation methods in the prior art has become an important technical problem to be solved by those skilled in the art.
