Embodiment 1

[0062] Such as figure 1 and figure 2 As shown, the embodiment of the first aspect of the present invention provides an air duct structure 100 of a rail vehicle 200, the air duct structure 100 includes a housing 110, an air duct 111 is formed in the housing 110, and the housing 110 has an air inlet 112, The first air outlet 113 and the second air outlet 114, the air inlet 112 is suitable for the main air duct 201 of the guide air channel 111 and the rail vehicle 200, the first air outlet 113 and the second air outlet 114 are distributed up and down, and are respectively configured as It communicates with the passenger compartment 202 of the rail vehicle 200 , wherein the airflow discharged from the air inlet 112 into the air duct 111 is discharged into the passenger compartment 202 through the first air outlet 113 and the second air outlet 114 .

[0063] In the air duct structure 100 provided in this embodiment, the casing 110 is provided with two air outlets, the air flow en...

Embodiment 2

[0069] Such as figure 2 As shown, on the basis of the above embodiments, this embodiment further defines: the air duct structure 100 of the rail vehicle 200 also includes a first air volume adjustment device 120, the first air volume adjustment device 120 is arranged at the air inlet 112, the second air volume adjustment device 120 An air volume adjusting device 120 is adapted to adjust the air intake volume of the air inlet 112 .

[0070] In this embodiment, the first air volume adjusting device 120 is set to adjust the air intake of the air inlet 112, so that the air intake of the air inlet 112 can be set according to specific usage requirements, and then the air output of the two air outlets can be changed, so that the air outlet The air outlet of the air outlet can better meet the needs of use and improve the comfort of passengers. And, because the first air volume regulating device 120 is arranged at the air inlet 112, like this, the excess air volume is blocked outside...

Embodiment 3

[0076] Such as image 3 and Figure 4 As shown, on the basis of the above embodiments, this embodiment further defines: the valve plate 121 includes a valve plate body 1211 and a flexible structure 1212 .

[0077] Specifically, the valve body 1211 is connected to the drive assembly, and the flexible structure 1212 is arranged on the edge of the valve body 1211. When the valve body 121 is in the closed position, the flexible structure 1212 seals the gap between the valve body 1211 and the inner wall of the housing 110 .

[0078] In this embodiment, the flexible structure 1212 is arranged on the edge of the valve body 1211. On the one hand, the sealing between the valve plate 121 and the inner wall of the housing 110 is realized through the flexible structure 1212, so as to ensure the sealing performance of the valve plate 121 when it is closed, and avoid Air leakage or abnormal noise. On the other hand, the flexible structure 1212 between the valve plate 121 and the inner wa...

Abstract

The invention provides an air duct structure of a railway vehicle, the railway vehicle and a control method thereof. The air duct structure comprises a shell, an air duct is formed in the shell, the shell is provided with an air inlet, a first air outlet and a second air outlet, the air inlet is suitable for guiding the air duct and a main air duct of the railway vehicle, the first air outlet andthe second air outlet are distributed up and down, and are respectively configured to be communicated with a passenger room of the railway vehicle, and airflow exhausted into the air duct from the airinlet is exhausted into the passenger room through the first air outlet and the second air outlet. The air duct structure is provided with the two air outlets, the air outlet efficiency of the air duct structure is improved through the design of the two air outlets, the air outlet amount is multiplied, and then the passenger room ventilation efficiency of the railway vehicle is improved. Due to the fact that the air outlet efficiency is improved, under the condition of the same air outlet amount, the air duct structure can achieve miniaturization design, and the air duct structure can be better suitable for small-section railway vehicles.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to an air duct structure of a rail vehicle, a rail vehicle and a control method for a rail vehicle. Background technique [0002] The existing small-section rail vehicles can greatly reduce the occupation of land resources due to the smaller body size of the larger-section rail vehicles. For cities with increasingly tight land resources, small-section rail vehicles are becoming more and more popular. [0003] However, due to the small section of the small-section rail vehicle, the installation space of the equipment is limited, and the design of the ventilation system is severely limited by the space. Specifically, limited by the space of the small-section rail vehicle, the air outlet and the air duct of the air duct structure are relatively narrow, and the air output volume of the air duct structure is greatly reduced, seriously affecting the ventilation of the compartment, and the pas...
