[0028] The present utility model discloses a door heat insulation mechanism for an alpine rail vehicle, which reduces the loss of energy inside the vehicle during the process of getting on and off passengers, saves energy, avoids large changes in the air temperature inside the carriage, and improves the comfort of passengers during the ride.
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figures 1 to 8 , the door heat insulation mechanism of the alpine rail vehicle of the present utility model includes an air curtain machine 2 arranged inside the door upright cover plate 4. The door upright cover plate 4 is provided with an air outlet 401 and an air inlet 402. The air outlet 401 is arranged on the side of the door upright cover plate 4 close to the vehicle door 1, and the air inlet 402 is arranged on other sides of the door upright cover plate 4. The air outlet side of the air curtain machine 2 is correspondingly arranged with the air outlet 401, so as to facilitate the air blown out by the air curtain machine 2 to blow towards the side of the vehicle door 1 close to the inner cavity of the carriage 3.
[0031] Wherein, the door upright cover plate 4 is arranged inside the inner compartment of the carriage 3. The vehicle door 1 is installed at the door position of the carriage 3. In order to save energy, when the vehicle door 1 is opened, the air curtain machine 2 starts to work.
[0032] The door heat insulation mechanism of the alpine rail vehicle of the present utility model generates a strong air current in the door area of the carriage 3 by arranging an air curtain machine 2 inside the door vertical cover plate 4 of the inner compartment of the carriage 3, and the air outlet 401 of the door vertical cover plate 4 is arranged on the side of the door vertical cover plate 4 close to the door 1. Thus, under the action of the air curtain machine 2, a blocking air curtain is formed at the door position, which is used to isolate the exchange of cold and hot air inside and outside the vehicle, does not affect passengers getting on and off the vehicle, achieves the purpose of reducing the energy loss inside the vehicle, saves energy, avoids large changes in the air temperature inside the carriage, and improves the comfort of passengers taking the vehicle.
[0033] In order to reduce the discomfort of passengers getting on and off the vehicle caused by the excessive wind force of the air curtain machine 2, two air curtain machines 2 are arranged. The two air curtain machines 2 are respectively arranged inside the door vertical cover plates 4 on both sides of the closed door 1, and the air outlets of the two air curtain machines 2 are arranged opposite to each other. The air blown out by the air curtain machines 2 on both sides of the door of the carriage 3 blows against each other, so that even if the wind force of the air curtain machine 2 is small, an air curtain can be formed. The structural method of arranging the air curtain machines 2 on both sides of the door 1, due to the corresponding blowing of the wind forces on both sides, can meet the requirement of forming an air curtain even when the wind force of the air curtain machine 2 is small, so that the air curtain machine 2 can meet the requirement in a state where the blown-out air is relatively gentle, and the use comfort is improved.
[0034] Specifically, the air outlet 401 is a long-strip opening. As Figure 7 shown, the length direction of the long-strip opening is arranged along the height direction of the door vertical cover plate 4, so as to form an air curtain that blocks the vehicle door opening along the height direction. For the convenience of maintenance, the door vertical cover plate 4 is detachably connected to the column 7 of the carriage 3 through a first connecting member 9, as Figure 3 and Figure 4 shown. In one embodiment, the first connecting member 9 is a bolt, and the door vertical cover plate 4 is connected to the column 7 of the carriage 3 through the first connecting member 8.
[0035] In one embodiment, the air curtain machine 2 is connected to the fixed bracket 5 through a second connecting member 8, and the fixed bracket 5 is connected to the column 7 of the carriage 3 through a third connecting member 6, so as to facilitate disassembly and assembly. Specifically, the second connecting member 8 includes a connecting bolt and a connecting nut used in cooperation, and the third connecting member 6 is a rivet. In other embodiments, other connecting members commonly used by those skilled in the art can also be used, which is not limited herein.
[0036] In order to improve the reliability of the connection, a plurality of fixed brackets 5 are arranged, and the plurality of fixed brackets 5 are at least connected to the upper and lower parts of the air curtain machine 2. In one embodiment, three fixed brackets 5 are arranged, and the three fixed brackets 5 are respectively connected to the upper, middle and lower parts of the air curtain machine 2, as Figure 5 shown, and each air curtain machine 2 is connected through six second connecting members 8.
[0037] In order to enable the air blown out by two relatively arranged air curtain machines 2 to form a counter jet, so that the air blown out by the two air curtain machines 2 forms an air curtain, the shapes and sizes of the air outlets 401 of the two air curtain machines 2 are the same, and the distances between the air outlets of the two air curtain machines 2 from the roof and the vehicle floor are the same, so that the air flows flowing out from the air outlets 401 of the two air curtain machines 2 form an air curtain, as Figure 6 and Figure 7 shown.
[0038] In order to improve the use safety of the door heat insulation mechanism of the alpine rail vehicle, a perforated plate is arranged at the air inlet 402 position of the door vertical cover plate 4, and a louver grille 403 or a perforated plate is arranged at the air outlet 401 position. Such a structural arrangement not only improves the use safety, but also can prevent foreign objects from entering the inner cavity of the door vertical cover plate 4 and improve the cleanliness of the inner cavity of the door vertical cover plate 4. When the perforated plate is adopted, the perforated plate is welded at the air outlet 401 position to form a seal at the air outlet 401 position. When the louver grille 403 is adopted, the louver grille 403 is rotatably connected to the air outlet 401 position. In an embodiment, as Figure 8 shown, a louver grille 403 is arranged at the air outlet 401 position, and the louver grille 403 can rotate, so as to facilitate the user to manually adjust the air volume of the air outlet.
[0039] Among them, Figure 1 , Figure 3 and Figure 4 the arrow directions in are the air flow directions of the air curtain machine 2. Figure 6 and Figure 7 the bent arrow directions in are the air flow directions after the air flows inside and outside the carriage encounter the counter jet air flow of the air curtain machine 2.
[0040] For the door heat insulation mechanism of the alpine rail vehicle of the present invention, by arranging air curtain machines 2 inside the door vertical cover plates 4 on both sides of the door 1 of the rail vehicle, and air outlets 401 are opened on the door vertical cover plates 4. Under the action of the air curtain machines 2, a strong air flow is generated in the door area of the rail vehicle, so as to form a shielding air curtain to isolate the exchange of cold and hot air inside and outside the vehicle, and achieve the purpose of reducing the energy loss inside the vehicle. The door heat insulation mechanism of the alpine rail vehicle of the present invention is applicable to alpine rail vehicles.
