Description

Embodiments of the present invention relate to an air conditioning unit housing for railway vehicles, an air conditioning unit for railway vehicles, and a railway vehicle. To facilitate the assembly of railway vehicle air conditioning systems (hereinafter also referred to as "air conditioning systems") and to standardize parts, the unitization of railway vehicle air conditioning system housings (hereinafter also referred to as "housings") is being promoted. In this case, to suppress the transmission of vibrations generated during railway vehicle operation to the air conditioning system, it is necessary to reduce the number of housing parts while increasing the rigidity of the housing. However, the housing contains strength components with different configurations depending on the railway vehicle to which the air conditioning system is installed. Therefore, standardizing the housing components is difficult. Furthermore, railway vehicle air conditioning system enclosures are required to have a structure that minimizes vibration of the internal components. However, if standardized enclosure components are not suitable for a particular railway vehicle, vibration may not be adequately suppressed. Japanese Patent Publication No. 2018-131037Patent No. 6305498 A schematic side view showing a railway vehicle according to one embodiment.A perspective view showing an air conditioning system for a railway vehicle according to one embodiment.A plan view showing an air conditioning system for a railway vehicle and a housing for the air conditioning system for a railway vehicle according to one embodiment.A perspective view showing a first base plate, a first riser, a second base plate, and a second riser according to one embodiment.A perspective view showing a first base plate, a second base plate, a first directional beam, and a second directional beam according to one embodiment.A plan view showing a modified example of an air conditioning unit housing for railway vehicles. The embodiments of the present invention will be described below with reference to the drawings. These embodiments are not intended to limit the present invention. In this specification, terms such as "parallel," "orthogonal," and "identical," as well as values of length and angle, which specify shapes, geometric conditions, and their degrees, are interpreted not in a strict sense, but to include a range that allows for the expectation of similar functionality. To clarify the directional relationships between drawings, some drawings show the first direction DA, the second direction DB, and the third direction DC as common directions across the drawings. In each direction, the tip of the arrow is the first side. In each direction, the side opposite to the first side is the second side. Arrows pointing away from the drawing plane in a direction perpendicular to the drawing plane are indicated by a symbol with an "x" inside a circle, as shown in Figure 1, for example. Arrows pointing away from the drawing plane in a direction perpendicular to the drawing plane are indicated by a symbol with a dot inside a circle, as shown in Figure 3, for example. Figure 1 shows a railway vehicle 100 having an air conditioning system 1 for railway vehicles according to this embodiment. The railway vehicle 100 is located on a track R. Sleepers (not shown) supporting the track R extend along a first direction DA. The track R extends along a second direction DB perpendicular to the first direction DA. Multiple sleepers are provided at intervals along the second direction DB. The railway vehicle 100 is movable along the track R in the second direction DB. In this case, the direction of the sleepers is the first direction DA, and the direction of travel is the second direction DB. Examples of railway vehicles 100 include electric trains, diesel railcars, locomotives, passenger cars, etc. In the illustrated example, the railway vehicle 100 is an electric train. The railway vehicle has a pantograph 105. In the example shown in Figure 1, the railway vehicle 100 has multiple (in this case, two) air conditioning units 1. The air conditioning units 1 are installed on the roof 101 of the railway vehicle 100. The multiple air conditioning units 1 are spaced apart from each other in the second direction DB. The air conditioning units 1 adjust the temperature, humidity, airflow, etc., of the air in the interior space of the railway vehicle 100. The air conditioning units 1 may exchange the air in the interior space of the railway vehicle 100 with the air outside the railway vehicle 100. That is, the air conditioning units 1 may have a ventilation function. The air conditioning units 1 may also have an air purification function in the interior space of the railway vehicle 100. Note that while Figure 1 uses a distributed system with multiple air conditioning units installed on the roof for explanation, it can also be applied to a centralized system with a single integrated unit.
