A double-decker train carriage and train

Abstract

Provided are a double-deck train carriage and a train. The double-deck train carriage comprises a carriage space enclosed by a top frame (201), a side wall (202), a bottom frame (203) and end walls (204). The carriage space comprises a passenger space and a passage space (208). In a passenger area, the passenger space is divided by a floor structure (205) into an upper passenger space (206) and a lower passenger space (207). An air supply system (209) is arranged in the carriage, and comprises an air conditioning unit (210) and an air supply duct (211) used for transferring flowing air output by the air conditioning unit (210) to the passenger space. The air conditioning unit (210) is arranged at the top of the passage space (208). The air supply duct (211) is arranged on at least one side, along the train traveling direction, at the top of the upper passenger space (206) and / or the top of the lower passenger space (207). By means of the present invention, the air supply system (209) can be rationally arranged in a space of the double-deck train with a compact structure, such that a simple structure and a small space occupation are ensured, while the requirements of the air supply amount for an upper layer, lower layer and middle layer of a double-deck passenger train are satisfied, thereby achieving a comfort requirement of a traveler.

Description

technical field [0001] The present application relates to railway vehicle traffic technology, in particular, to a double-decker train carriage and train. Background technique [0002] Due to high-speed rail transit trains' good safety performance, high comfort, fast speed and reasonable price, more and more passengers choose to travel by high-speed trains. [0003] In recent years, the number of passengers taking high-speed trains has increased significantly. In order to increase the passenger capacity of high-speed EMU trains, in recent years, double-decker high-speed trains with larger passenger capacity have been gradually developed. As an important ventilation device in the car, the air supply system has become one of the important components of high-speed trains. However, at present, domestic high-speed EMU trains are all single-deck trains, and their air supply systems are only designed for the air supply requirements of single-deck trains. design. [0004] Such as ...

AI Technical Summary

Problems solved by technology

[0006] The main air duct of the existing air supply system occupies the entire space on the top of the carriage, which occupies too much effective space in the carriage. The layout of double-deck trains is relatively compact, and it is impossible to apply the air supply system of single-deck trains to double-deck trains; Simultaneously, as long as the air supply volume of the existing air supply system is aimed at the interior use space of a single-deck train, the interior use space of a double-decker train is larger than that of a single-car train, and the air supply volume of the single-car train air supply system 209 cannot meet the requirements of a double-decker train. needs
