A rail vehicle and its sunshade

Abstract

The invention provides a sunshade curtain, comprising: a cord, the cord includes: a first cord, a middle cord and a second cord; a jacking tube, the jacking tube includes: a first section, a middle section and a second section connected in sequence, the first section , The middle section and the second section are not collinear, the top of the first curtain is installed on the first section, the top of the middle curtain is installed on the middle section, and the top of the second curtain is installed on the second section; the first guide rods are respectively installed at both ends of the jacking pipe and the second guide rod; it can slide along the first guide rod and the second guide rod, and is used for installing the first curtain, the middle curtain and the tie rod at the bottom of the second curtain. This scheme realizes the arc structure of the jacking pipe through the non-collinear design of the three sections of the jacking pipe, and then cooperates with the three curtains designed as the arc skeleton of the jacking pipe to realize the hyperboloid structure of the sunshade curtain. Matching the inclination angle of the front window glass, so as to adapt to the streamlined shape of the hood of the EMU, the invention also provides a rail vehicle using the above-mentioned sunshade curtain.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle and a sunshade thereof. 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; and according to the owner's requirement for the double-driver layout, the driver's cab has a relatively large horizontal dimension. The width of the sunshade reaches 2 meters; and due to the streamlined head shape design, the longitudinal height of the driver's seat in the cab is about 1.7 meters. In order to ensure that the driver can stand and operate, the sunshade cannot occupy too much height space on the top of the cab. [0003] According to the previous models of sunshades, the sunshades are all straight-facing 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, considerin...

[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
