Railway vehicle and sunshade curtain thereof

Abstract

The invention provides a sunshade curtain which comprises curtain cloth, a jacking pipe, a first guide rod, a second guide rod and a tie rod, wherein the curtain cloth comprises first curtain cloth, middle curtain cloth and second curtain cloth; the jacking pipe comprises a first section, a middle section and a second section which are connected in sequence, the first section, the middle section and the second section are not collinear, the top of the first curtain cloth is installed on the first section, the top of the middle curtain cloth is installed on the middle section, and the top of the second curtain cloth is installed on the second section; the first guide rod and the second guide rod are respectively arranged at two ends of the jacking pipe; and the tie rod can slide along the first guide rod and the second guide rod and is used for mounting the bottoms of the first curtain cloth, the middle curtain cloth and the second curtain cloth. According to the scheme, the non-collinear design of the three sections of the jacking pipe is adopted, the arc structure of the jacking pipe is achieved, the three pieces of curtain cloth designed as the jacking pipe of the arc framework are matched, the double-curved-surface structure of the sunshade curtain is achieved so as to be matched with the inclination angle of front window glass, and therefore the sunshade curtain can adapt to the streamline shape of a hood of a motor train unit. The invention further provides a rail vehicle applying the sunshade curtain.

Description

Technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle and its sunshade. Background technique [0002] The head shape of the EMU is a streamlined design, resulting in a multi-curved hood at the front of the driver’s cab. According to the layout of the double driver required by the owner, the horizontal size of the driver’s cabin is large. In order to meet the good vision of the main and co-drivers, the front window glass and The width of the sun shade is up to 2 meters; and due to the streamlined head design, the longitudinal height of the driver's seat in the driver's cabin is about 1.7 meters. In order to ensure that the driver can stand up and operate, the sun shade cannot occupy the excessive height space on the top of the cab. [0003] According to previous models of sun shades, the sun shades are all straight-faced structures, which are difficult to match the inclination angle of the front window glass, and fail t...

AI Technical Summary

Problems solved by technology

[0003] According to the previous models of sunshades, the sunshades are all straight-faced structures, which are difficult to match the inclination angle of the front window glass, and cannot well adapt to the streamlined shape of the EMU hood

Moreover, considering the maintenance and repair work of the sunshade, the installation framework and installation screws of the sunshade can only be exposed, which seriously affects the appearance of the driver's cab
