Driver's cab air duct for urban train and urban train

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202311152694.6 filed with the Patent Office of China on September 7, 2023, entitled “A driver's cab air duct for urban trains and urban trains,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of urban rail trains, and in particular to a driver's cab air duct for an urban rail train and an urban rail train. Background Art

[0004] Urban rail, also known as urban rail transit, is an urban public rail transit system based on railway technology and equipment that operates specifically between neighboring cities and urban areas. It is a fast, large-capacity, bus-like public transportation method that connects urban areas with suburbs and satellite towns or urban circles within dozens of kilometers or even larger areas around the city.

[0005] Intercity trains are a new type of rail transit tailor-made for urban rail transit. They lie somewhere between urban rail transit (subways and light rail) and intercity high-speed rail. Existing rail transit options like subways and light rail are limited by operating speeds and are no longer able to meet the mobility needs of residents in urban development. Compared to urban rail transit, intercity trains feature larger average station spacing, larger passenger capacity, higher target speeds, higher travel speeds, and moderate traffic density.

[0006] The driver's cab of a metropolitan train is located at the front of the train. Due to its structural characteristics, the front of the train is relatively short, which limits the installation space for the driver's cab. Consequently, existing metropolitan trains only have ventilation above the driver's head, resulting in poor comfort.

DETAILED DESCRIPTION

[0026] The following detailed description is provided to help the reader gain a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes and modifications to the methods, devices, and / or systems described herein and their equivalents will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. In addition, except for operations that must occur in a particular order, changes may be made that will be apparent upon understanding the disclosure of this application. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity.

[0027] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0028] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, it may be directly “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on,” “directly connected to,” “directly coupled to,” “directly over,” or “directly covering” another element, there may be no other elements intervening therebetween.

[0029] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0030] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are used only to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Thus, a first member, component, region, layer, or portion in the examples described herein may also be referred to as a second member, component, region, layer, or portion without departing from the teachings of the examples.

[0031] For ease of description, spatial relational terms such as "above," "upper," "below," and "lower" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings. Such spatial relational terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element described as being "above" or "upper" relative to another element would subsequently be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations "above" and "below," depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.

[0032] The terms used herein are intended to describe various examples only and are not intended to limit the examples. Unless the context clearly indicates otherwise, the singular form is intended to include the plural form. The terms "include," "comprising," and "having" list the presence of stated features, quantities, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0033] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include changes in shapes that occur during manufacturing.

[0034] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.
