Disclosure of the invention

[0004] In the former vehicle, in order to reduce the floor as described above, an air conditioner for air conditioning in the passenger compartment may be arranged on the roof. In this case, if the gas fuel cylinder is arranged on the roof, there is a risk that the gas fuel leaking the gas fuel cylinder force may enter the passenger compartment through the outside air inlet of the air conditioner unit.

[0005] By the way, considering the case where such a fuel cell device is mounted on a vehicle such as a bus, a gas tank for storing hydrogen gas and the like is arranged on the roof in order to lower the floor so as not to impair getting on and off. It may be preferable to do this. In this case, a considerable part of the space on the roof The gas tank occupies a large amount of power, which may make it difficult to place the radiator at a position where sufficient running wind can be introduced, and may not allow sufficient space for gas tank maintenance work. is there.

[0006] One object of the vehicle of the present invention is to prevent gas fuel leaking from the gas fuel tank car from entering the passenger compartment. Another object of the vehicle of the present invention is to appropriately arrange the air conditioner unit and the gas fuel tank on the roof. Another object of the vehicle of the present invention is to improve the cooling efficiency of the power source radiator while securing the space for disposing the gas fuel tank. Alternatively, the vehicle of the present invention has one of the purposes to arrange the gas fuel tank and the power source radiator more appropriately on the roof.

[0007] The vehicle of the present invention employs the following means in order to achieve at least a part of the above-described object.

[0008] A first vehicle of the present invention is a vehicle that travels using power from a power source, and stores a gas fuel supplied to the power source, and a gas fuel tank disposed on a roof of a vehicle body. An air-conditioning unit that is disposed in front of the gas fuel tank on the roof of the vehicle body in the front-rear direction of the vehicle, has an outside air introduction port for introducing outside air, and air-conditions the passenger compartment using the outside air introduced from the outside air introduction port And a gist of the above.

In the first vehicle of the present invention, a gas fuel tank is disposed on the roof of the vehicle body, and an air conditioning unit is disposed in front of the gas fuel tank. Accordingly, since the gas fuel leaked from the gas fuel tank flows backward due to the traveling wind, compared with the case where the air conditioning unit is arranged behind the gas fuel tank, the gas fuel passes through the outside air inlet of the air conditioning unit. It is possible to more appropriately prevent the intrusion into. Here, the gas fuel tank is placed horizontally on the vehicle roof so that the longitudinal direction is the vehicle width direction, or is placed horizontally on the vehicle roof so that the longitudinal direction is the front-rear direction of the vehicle, It may be arranged vertically on the roof of the vehicle body so that the longitudinal direction is the vehicle width direction or the vehicle longitudinal direction.

[0010] In the first vehicle of the present invention, the gas fuel tank may be disposed at a substantially central portion in the vehicle front-rear direction on the vehicle body roof. In this way, the gas fuel tank, which has a relatively large weight, is arranged at the approximate center in the vehicle front-rear direction. It can be assumed that the lance has been removed. As a result, vehicle mobility such as turning performance can be improved. In this case, the gas fuel tank is placed horizontally on the vehicle roof so that the longitudinal direction is the vehicle width direction, or is placed horizontally on the vehicle roof so that the longitudinal direction is the vehicle longitudinal direction. It may be arranged vertically on the car roof so that is in the vehicle width direction or the vehicle longitudinal direction. The gas fuel tank may be formed in a substantially cylindrical shape.

[0011] Furthermore, the first vehicle of the present invention includes a roof cover that covers at least the gas fuel tank and the air conditioning unit, and has an outside air induction port that guides outside air to the outside air introduction port of the air conditioning unit. It can also be. In this case, the air conditioning unit is formed at a height lower than that of the gas fuel tank, and the roof cover is formed such that the upper part of the air conditioning unit is lower than the upper part of the gas fuel tank. It can also be. In this way, the shape of the front of the roof cover can be made to rise from the top of the air conditioning unit to the top of the gas fuel tank. As a result, the aerodynamic resistance of the vehicle can be reduced by / J.

[0012] In the first vehicle of the present invention including the roof cover, the roof cover may include an isolation part that separates the outside air introduction port of the air conditioning unit and the gas fuel tank. it can. In this way, it is possible to more reliably prevent the gas fuel leaked from the gas fuel tank cover from entering the passenger compartment. In the vehicle of this aspect of the present invention, the roof cover may be formed with a ventilation hole in the upper part behind the central force in the vehicle longitudinal direction. In this way, since the ventilation hole and the air conditioning unit can be separated from each other, the gas fuel released to the outside through the ventilation hole from the inside of the roof cover enters the passenger compartment through the outside air inlet of the air conditioning unit. Can be suppressed.

[0013] Further, the first vehicle of the present invention is provided with a radiator that is arranged in the front-rear direction of the vehicle from the gas fuel tank on the roof of the vehicle body and is used for a cooling system of the power source. You can also. This makes it easier to mix the gas fuel tank force with the traveling wind introduced into the radiator behind the leaked gas fuel force, so that gas fuel can be more appropriately prevented from entering the passenger compartment. it can.

[0014] In the first vehicle of the present invention of the aspect comprising this radiator, the vehicle body roof is covered, A roof cover provided with an upper outside air inlet that opens so as to introduce outside air that passes upward as the vehicle travels into the radiator may be provided. In this way, the radiator can be cooled using outside air passing above the gas fuel tank. As a result, it is possible to improve the cooling efficiency of the power source radiator while securing the arrangement space for the gas fuel tank. Further, since the upper outside air inlet is provided behind the gas fuel tank, the gas fuel leaked from the gas fuel tank can be diluted with outside air introduced into the upper outside air inlet. Here, the upper outside air introduction port for introducing the outside air passing through the upper side into the radiator is provided in comparison with the case where the side outside air introduction port for introducing the outside air passing through the side into the radiator is provided. In order to sufficiently introduce the outside air passing through the side, it is necessary to introduce the outside air from the front (as viewed from the direction of the gas fuel tank) as much as possible, which reduces the space near both ends of the gas fuel tank in the vehicle width direction. This is based on the idea that introducing outside air that passes through the air will allow sufficient outside air to be introduced and also ensure the maintenance space for the gas fuel tank.

[0015] In the first vehicle of the present invention having such a radiator and a roof cover, the roof cover is located at the rearmost position in the vehicle front-rear direction of the gas fuel tank, from above the gas fuel tank to the upper side. A downwardly inclined surface that descends to the lower end of the outside air inlet may be provided. By so doing, outside air can be guided to the upper outside air inlet by effectively utilizing the shape of the substantially cylindrical gas fuel tank. Further, in this case, the roof cover may be provided with wall portions on both sides in the vehicle width direction of the descending inclined surface. In this way, it is possible to more appropriately guide the outside air to the upper outside air inlet.

[0016] Further, in the first vehicle of the present invention including a radiator and a roof cover, a plurality of the radiators are juxtaposed in the front-rear direction of the vehicle front-rear direction, and the roof cover has a plurality of upper outside air inlets. Outside air is introduced into a radiator disposed on the front side of the radiator, and the roof cover introduces outside air passing through the side as the vehicle travels to a radiator located on the rear side of the plurality of the radiators. It is also possible to provide a side air inlet that is open at the side. In this way, a plurality of radiators can be arranged in a compact manner, and the cooling efficiency of each radiator can be made more appropriate. be able to. In this case, the two radiators may be juxtaposed in the vehicle width direction on the front side and two juxtapositions in the vehicle width direction on the rear side.

[0017] A second vehicle of the present invention is a vehicle that travels using power from a power source, stores gas fuel to be supplied to the power source, and is disposed on a roof of a vehicle body. A fuel tank, a radiator used for the cooling system of the power source, disposed behind the gas fuel tank on the vehicle body roof in the vehicle front-rear direction, and covers the vehicle body roof. And a roof cover provided with an upper outside air inlet that opens to introduce the passing outside air into the radiator.

[0018] In the second vehicle of the present invention, a gas fuel tank is disposed on the roof of the vehicle body, and a power source radiator is disposed behind the gas fuel tank, and passes upward as the vehicle travels. An upper outside air inlet for introducing outside air (running wind) into the radiator is provided on the roof cover that covers the roof of the vehicle body. Therefore, the radiator can be cooled using outside air passing above the gas fuel tank. As a result, it is possible to improve the cooling efficiency of the power source radiator while ensuring the space for disposing the gas fuel tank. In addition, since the upper outside air inlet is provided behind the gas fuel tank, the gas fuel leaked from the gas fuel tank can be diluted using the outside air introduced into the upper outside air inlet. Here, the upper outside air introduction buro which introduces the outside air passing through the upper side to the radiator is provided in comparison with the case where the side outside air introduction port for introducing the outside air passing through the side into the radiator is provided. It is necessary to introduce the outside air from the front (toward the gas fuel tank) as much as possible in order to sufficiently introduce the outside air that passes through the tank, and this reduces the space near both ends of the gas fuel tank in the vehicle width direction. This is based on the fact that it is considered that sufficient outside air can be introduced and a maintenance space for the gas fuel tank can be secured. Here, the gas fuel tank is placed horizontally on the vehicle roof so that the longitudinal direction is the vehicle width direction, or is placed horizontally on the vehicle roof so that the longitudinal direction is the longitudinal direction of the vehicle. It may be arranged vertically on the roof of the vehicle body so that the direction is the vehicle width direction or the vehicle longitudinal direction. The gas fuel tank may be formed in a substantially cylindrical shape.

[0019] Also, in the second vehicle of the present invention, the roof cover includes a gas fuel tank. Of these, a downwardly inclined surface that descends from the upper side of the gas fuel tank located at the rearmost in the vehicle longitudinal direction to the lower end of the upper outside air inlet may be provided. In this way, outside air can be guided to the upper outside air inlet by effectively utilizing the shape of the substantially cylindrical gas fuel tank. In this case, the roof cover may be provided with wall portions on both sides of the descending inclined surface in the vehicle width direction. In this way, outside air can be more appropriately guided to the upper outside air inlet.

[0020] Further, in the second vehicle of the present invention, a plurality of the radiators are juxtaposed in the longitudinal direction of the vehicle, and the upper outside air inlet of the roof cover is disposed on the front side of the plurality of the radiators. The roof cover has a side outside air inlet that opens to introduce outside air passing through the side as the vehicle travels to a radiator disposed behind the plurality of radiators. It can also be provided on the side. In this way, a plurality of radiators can be arranged in a compact manner, and the cooling efficiency of each radiator can be made more appropriate. In this case, the two radiators are juxtaposed in the vehicle width direction on the front side and two in the vehicle width direction on the rear side.

FIG. 22 is an explanatory diagram for explaining the arrangement of hydrogen tanks 30 and the like in FIG. As shown in the figure, the fuel cell-mounted bus 20 of the embodiment is configured as a large bus that travels using the fuel cells 40a and 40b as a power source, and the fuel cells 40a and 40b are located at the bottom of the rear part of the roof 2 2. Seven hydrogen tanks 30 that are substantially cylindrical and store hydrogen as fuel to be supplied to the fuel cells 40a and 40b are mounted on the center in the front-rear direction. In addition to the seven hydrogen tanks 30 on the roof 22 of the fuel cell-mounted bus 20, an air conditioner unit 60 that air-conditions the passenger compartment in front of the hydrogen tank 30 and fuel cells 40a, 40b in the rear A plurality of radiators 42 are mounted on the ceiling, and are covered with a roof cover 50 having a plurality of ventilation openings 51 attached to the ceiling.

[0023] As shown in FIG. 2, a pressure regulating valve for adjusting the pressure of hydrogen supplied to the fuel cells 40a and 40b and a high temperature (eg, 110 ° C or higher) are provided at one end in the longitudinal direction of the hydrogen tank 30. A valve unit 32 that incorporates a plug valve as a safety valve that melts and releases the hydrogen in the tank to the outside is installed, so that this valve unit 32 is on the right side of the fuel cell bus 20 In addition, the belt 39 is mounted on the roof 22 so that its longitudinal direction is the vehicle width direction.

[0024] As shown in Fig. 1, an upwardly inclined surface 50a is formed at the front portion of the roof cover 50 so that the foremost force also rises to the upper part of the hydrogen tank 30 through the upper part of the air conditioner unit 60. In the middle of the inclined surface 50a, provided in the upper front part of the air conditioner unit 60, the outside air guiding part 52 (see Fig. 4) for guiding the outside air to the outside air inlet 60a of the air conditioner 60, and the hydrogen tank 30 of the air con unit 60 A partition wall 54 is provided in the side periphery to separate the hydrogen tank 30 and the air conditioner unit 60 from each other. Here, the upward inclined surface 50a reduces the aerodynamic resistance of the fuel cell-mounted bus 20. In the partition wall 54, hydrogen leaked from the hydrogen tank 30 flows into the outside air inlet 60a of the air conditioner unit 60 through the roof cover 50. Is preventing.

[0025] In addition to the ventilation hole 51, the roof cover 50 is provided at both the left and right corners behind the hydrogen tank 30, and the upper outside air introduction section 56 introduces the traveling wind above the ceiling section to the radiator 42. In addition, a side outside air introduction section 58 that is provided on both the left and right side surfaces slightly behind the upper outside air introduction section 56 and that introduces the side traveling wind to the radiator 42 is provided. The upper outside air introduction section 56 includes an outside air introduction port 56a that opens forward, and a downwardly inclined surface in which the upward force of the hydrogen tank 30 located at the rear end also falls along the outer peripheral surface of the hydrogen tank 30 to the lower end of the outside air introduction port 56a. 56b and wall portions 56c provided on both the left and right sides of the descending inclined surface 56b, so that the traveling wind guided by the descending inclined surface 56b and the wall portion 56c is introduced into the outside air introduction port 56a. It has become.

[0026] The air conditioner unit 60 sends the outside air guided to the outside air introduction port 60a by the outside air guiding portion 52 of the roof cover 50 and the inside air introduced from the passenger compartment into the passenger compartment as cold air or hot air with heat exchange. To air-condition the passenger compartment. The radiator 42 is connected to the fuel cells 40a and 40b via a cooling pipe 44 through which cooling water as a cooling medium circulates.

Cooling water circulating through the cooling pipe 44 is cooled by heat exchange with the traveling wind introduced by the upper outside air introduction portion 56 and the side outside air introduction portion 58 of the cover 50.

[0027] The radiator 42 is connected to the fuel cells 40a and 40b through a cooling pipe 44 through which cooling water as a cooling medium circulates, and is connected to the upper outside air introduction section 56 and the side outside air introduction section 58 of the roof cover 50. The cooling water circulating through the cooling pipe 44 is cooled by heat exchange with the introduced traveling wind. FIG. 5 is an explanatory diagram showing an arrangement relationship between the plurality of radiators 42. As shown in the drawing, the radiator 42 is arranged in series with a predetermined angle (for example, any angle between 15 degrees and 60 degrees) with respect to the center line in the longitudinal direction of the vehicle and mirrored with respect to the center line. Consists of four radiators 42a and 42b, the two front radiators 42a are cooled by the driving air introduced from the upper outside air introduction section 56, and the two rear radiators 42b are introduced from the side outside air introduction section 58. It is cooled by running wind. The traveling wind introduced by the upper outside air introduction unit 56 and the side outside air introduction unit 58 is exhausted from the exhaust port 59.

[0028] Here, the upper outside air introduction part 56 for introducing the traveling wind into the front radiator 42a Compared to the case where side running wind is introduced in the same way as the air introduction section 58, in this case, it is necessary to provide a running wind introduction section from the front as much as possible in order to introduce sufficient running wind. As a result, the space in the vicinity of the valve unit 32 of the hydrogen tank 30 is reduced, which affects the maintenance work of the valve unit 32 (see FIG. 6). In addition, if an attempt is made to secure a space near the valve unit 32, the traveling wind introduction portion cannot be provided in front, and the traveling wind that can be introduced becomes insufficient, leading to a decrease in the cooling efficiency of the radiator 42a. (See Fig. 7). On the other hand, according to the upper outside air introduction unit 56 of the embodiment, it is possible to introduce more sufficient traveling air and to secure a space near the valve unit 32 of the hydrogen tank 30.

[0029] According to the fuel cell mounting bus 20 of the embodiment described above, the hydrogen tank 30 is disposed on the roof 22, and the air conditioner unit 60 is disposed in front of the hydrogen tank 30, thereby providing a hydrogen tank. Since hydrogen leaked from 30 flows backward due to the driving wind, hydrogen leaked from hydrogen tank 30 passes through outside air inlet 60a of air conditioner unit 60, compared to the case where air conditioner 60 is placed behind hydrogen tank 30. Can be more appropriately prevented from entering the passenger compartment. In addition, since the hydrogen tank 30 is disposed at a substantially central portion in the front-rear direction on the roof 22, the vehicle body can be balanced in weight, and vehicle mobility such as turning performance can be improved. Furthermore, since the radiator 42 is disposed behind the hydrogen tank 30, hydrogen leaked from the hydrogen tank 30 is introduced into the radiator 42 by the upper outside air introduction section 56 and the side outside air introduction section 58, and hydrogen enters the passenger compartment. It is possible to prevent this more appropriately.

[0030] Further, according to the fuel cell mounting bus 20 of the embodiment, since the upward slope 50a is formed in the front portion of the roof cover 50, aerodynamic resistance can be reduced. Furthermore, since the roof force bar 50 is provided with the partition wall portion 54 that separates the hydrogen tank 30 and the air conditioner unit 60, it is possible to more reliably prevent hydrogen leaking from the hydrogen tank 30 from entering the passenger compartment.

[0031] Furthermore, according to the fuel cell-mounted bus 20 of the embodiment, the radiator 42 is disposed behind the hydrogen tank 30 on the roof 22, and the upper outside air introduction section that introduces the upper traveling wind into the radiator 42. Since 56 is provided on the roof cover 50, the radiator 42 can be cooled using the upper traveling wind. As a result, the space for the hydrogen tank 30 is secured. Therefore, the cooling efficiency of the radiator 42 can be improved. Further, the hydrogen leaking from the hydrogen tank 30 can be diluted using the outside air introduced into the upper outside air introduction section 56.

[0032] In the fuel cell bus 20 of the embodiment, the hydrogen tank 30 may be disposed in front of or behind the force on the roof 22 that is disposed in the approximate center in the front-rear direction.

In the fuel cell-mounted bus 20 of the embodiment, the force that the radiator 42 is disposed behind the hydrogen tank 30 is not limited to this, and the radiator 42 does not necessarily need to be disposed on the roof 22.

[0034] In the fuel cell-mounted bus 20 of the embodiment, the upper outside air introduction part 56 is configured by the outside air introduction port 56a, the lower inclined surface 56b, and the wall part 56c. As long as it can be introduced, it is not always necessary to provide the downward slope 56b and the wall 56c.

In the fuel cell-mounted bus 20 of the embodiment, the image is mirrored in series with a predetermined angle (for example, any angle of 15 degrees to 60 degrees) with respect to the center line in the longitudinal direction of the vehicle. The four radiators 42a and 42b arranged as described above constitute the radiator 42. However, regardless of the arrangement, the traveling wind introduced by the upper outside air introduction section 56 is introduced into the radiator 42 arranged on the front side. The traveling wind introduced by the side outside air introduction unit 58 may be arranged so as to be introduced to the radiator 42 arranged on the rear side. Of course, the number of radiators 42 is not limited to four, but may be one or other plural.

[0036] In the fuel cell-mounted bus 20 of the embodiment, seven hydrogen tanks 30 formed in a substantially cylindrical shape are placed horizontally on the roof 22 so that the longitudinal direction thereof is in the vehicle width direction. However, the hydrogen tank 30 is not limited to a substantially cylindrical shape, and the hydrogen tank 30 may have any shape. Any direction such as the front-rear direction may be used. In addition, it is not necessary to arrange horizontally on the roof 22, and it may be arranged vertically.

[0037] In the fuel cell-mounted bus 20 of the embodiment, the force inclined surface 50a formed on the front portion of the roof cover 50 may not include the upwardly inclined surface 50a. In addition, a partition wall 54 is provided to separate the hydrogen tank 30 and the air conditioner unit 60 from each other. It does not matter if it is not provided. Further, the air conditioner unit 60 and the hydrogen tank 30 may not be covered by the roof cover 50.

[0038] In the fuel cell-equipped bus 20 of the embodiment, the force is assumed to be provided with a plurality of ventilation ports 51 in the ceiling portion of the roof cover 50. All the ventilation ports 51 are arranged behind the central force in the vehicle longitudinal direction. It may be. In this way, the outside air inlet 60a and the ventilation port 51 of the air conditioner unit 60 can be further separated from each other, so that hydrogen released from the inside of the roof cover 50 through the ventilation port 51 is discharged to the outside air inlet of the air conditioner unit 60. It is possible to prevent the passenger from entering the passenger compartment via 60a. Further, such a ventilation port 51 may not be provided.

[0039] The fuel cell mounted bus 20 of the embodiment is not limited to the power using hydrogen gas as the gas fuel, and may of course be other gas fuel such as natural gas. Further, the power for mounting the fuel cells 40a and 40b as a power source is not limited to this, and an engine using gas fuel such as hydrogen or natural gas may be mounted as a power source.

As described above, the best mode for carrying out the present invention has been described using examples. However, the present invention is not limited to these examples, and is within the scope of the present invention. Of course, it can be implemented in various forms.
