[0009] Hereinafter, embodiments will be described with reference to the drawings. In the following description, directions are based on the directions of the off-road vehicle 1 unless otherwise defined, and the fore-and-aft direction of the vehicle corresponds to the vehicle length direction, and the vehicle width direction corresponds to the vehicle left-right direction.

[0010] Fig. 1 is a left side view of an off-road vehicle 1 according to an embodiment. As shown in Fig. 1, the off-road vehicle 1 includes a body frame 2, a pair of left and right front wheels 3 that support a front portion of the body frame 2, and a pair of left and right rear wheels 4 that support a rear portion of the body frame 2. The tires on the front wheels 3 and rear wheels 4 may be, for example, balloon tires for traveling on rough terrain. The off-road vehicle 1 may also be called a utility vehicle.

[0011] The vehicle body frame 2 is a pipe frame formed by connecting multiple pipes together. The vehicle body frame 2 has a floor frame 2a and a cabin frame 2b. The floor frame 2a supports the passenger seat 6 from below via a seat support frame. The cabin frame 2b defines a cabin C in which the passenger seat 6 is disposed. A floor panel 19 is disposed above the floor frame 2a. The floor panel 19 defines the cabin C from below. The floor panel 19 includes a floor surface 19a disposed in front of and below the passenger seat 6. The feet of a passenger seated in the passenger seat 6 are placed on the floor surface 19a of the floor panel 19.

[0012] A front cover 5 supported by the body frame 2 is disposed in front of the cabin C. The front cover 5 covers the front space S1 between the left and right front wheels 3 from above. The front cover 5 may include a front hood, front side cowls, and a front grill. Side doors 7 are disposed on both sides of the cabin C to open and close boarding gates through which passengers enter and exit the cabin C.

[0013] A dash panel 8 that separates the front space S1 from the cabin C is supported on the body frame 2. A dashboard 9 is disposed behind the dash panel 8 and in front of the passenger seat 6. The dashboard 9 faces the passenger seat 6 from the front. Instruments are provided on the dashboard 9. A handle 10 that faces the passenger seat 6 is disposed on the dashboard 9. An accommodation space S2 is defined between the dash panel 8 and the dashboard 9.

[0014] A luggage rack 11 is disposed behind the cabin frame 2b, defining a recessed loading space that is open upward to the outside of the vehicle. An internal combustion engine 12 supported by the body frame 2 is disposed behind the passenger seat 6 as a prime mover. At least a portion of the internal combustion engine 12 is disposed vertically below the luggage rack 11 in a side view of the vehicle. The internal combustion engine 12 is disposed behind the front end of the passenger seat 6. When the passenger seat 6 is slidable in the fore-and-aft direction of the vehicle, the internal combustion engine 12 is located behind the front end of the passenger seat 6 throughout the entire sliding range of the passenger seat 6.

[0015] A continuously variable transmission 13 is adjacent to the internal combustion engine 12. The continuously variable transmission 13 changes the rotation speed of the driving force output by the internal combustion engine 12. The driving force output from the continuously variable transmission 13 is transmitted to one or both of the front wheels 3 and the rear wheels 4. Note that although the internal combustion engine 12 is described as the prime mover for driving, the prime mover may be a combination of an internal combustion engine and an electric motor, or may be an electric motor alone.

[0016] The off-road vehicle 1 is equipped with an air conditioning system 20. An air conditioner 21 of the air conditioning system 20 is disposed forward of the dashboard 9. Specifically, the air conditioner 21 is disposed in an accommodation space S2 defined between the dash panel 8 and the dashboard 9. A condenser 25 of the air conditioning system 20 is disposed in the front space S1. A radiator 16 for cooling the internal combustion engine 12 is disposed in the front space S1. An electric compressor 24 is disposed forward of the dash panel 8 and the dashboard 9. Specifically, the electric compressor 24 is disposed in the front space S1. The electric compressor 24 includes a refrigerant compressor and an electric motor that drives the refrigerant compressor.

[0017] A soundproofing sheet 18 is attached to the dash panel 8 to prevent the operating sound of the electric compressor 24 from being transmitted to the cabin C. The soundproofing sheet 18 may be a sound-insulating material or a sound-absorbing material. The sound-insulating material may be, for example, a lead sheet. The sound-absorbing material may be, for example, a sheet with many irregularities or many holes. The soundproofing sheet 18 may be attached to the front cover 5 or to the dashboard 9.

[0018] FIG. 2 is a left side view of the off-road vehicle 1 showing the piping of the air conditioning system 20 and the like shown in FIG. 2. As shown in FIG. 2, the air conditioning system 20 includes an evaporator 22, a blower 23, an electric compressor 24, a condenser 25, and an expansion valve 26 for cooling purposes. The air conditioner 21, located in the accommodation space S2 between the dash panel 8 and the dashboard 9, includes the evaporator 22 and the blower 23. The evaporator 22 vaporizes the refrigerant and removes heat of vaporization from the surrounding area. The blower 23 includes a blower vane 23a and an electric motor 23b that drives the blower vane 23a. The blower 23 generates an air flow that passes through the evaporator 22, sending cool air into the cabin C.

[0019] The evaporator 22 is connected to the electric compressor 24 via a first refrigerant flow path 28. The electric compressor 24 is disposed forward of the dashboard 9. Specifically, the electric compressor 24 is disposed in the front space S1. The electric compressor 24 is connected to the condenser 25 via a second refrigerant flow path 29. The condenser 25 exchanges heat with outside air to lower the temperature of the refrigerant. The condenser 25 is connected to the evaporator 22 via a third refrigerant flow path 30.

[0020] An expansion valve 26 is arranged in the third refrigerant flow path 30. The expansion valve 26 reduces the pressure and temperature of the refrigerant flowing from the condenser 25 to the evaporator 22. The refrigerant that reaches the evaporator 22 from the expansion valve 26 exchanges heat with outside air in the evaporator 22 and is evaporated. The first refrigerant flow path 28, the second refrigerant flow path 29, and the third refrigerant flow path 30 are all arranged in front of the dashboard 9.

[0021] In the front space S1, a radiator 16 is disposed behind the condenser 25. The internal combustion engine 12 is connected to the radiator 16 via a first refrigerant flow path 35. The refrigerant heated to a high temperature by the internal combustion engine 12 is sent to the radiator 16 via the first refrigerant flow path 35. The radiator 16 is connected to the internal combustion engine 12 via a second refrigerant flow path 36. The refrigerant whose temperature has been reduced in the radiator 16 is sent to the internal combustion engine 12 via the second refrigerant flow path 36.

[0022] A radiator fan 17 is provided behind the radiator 16. The radiator fan 17 includes a fan vane 17a and an electric motor 17b that drives the fan vane 17a. The radiator fan 17 is disposed so as to blow air toward the rear of the vehicle. When the radiator fan 17 is driven, outside air passes through the radiator 16, forcing the radiator 16 to be air-cooled. The condenser 25 is disposed so as to overlap the radiator 16 from the front of the vehicle, so when the radiator fan 17 is driven, outside air passes through both the condenser 25 and the radiator 16.

[0023] The electric compressor 24 is disposed behind the radiator fan 17. A fan wind shield 39 is interposed between the radiator fan 17 and the electric compressor 24. The fan wind shield 39 guides the hot air flowing from the radiator fan 17 toward the electric compressor 24 so that the hot air does not directly hit the electric compressor 24. For example, the fan wind shield 39 may be an air guide plate that guides the hot air flowing rearward from the radiator fan 17 downward and rearward.

[0024] The air conditioning system 20 includes a heater 27 included in the air conditioner 21 for heating. The heater 27 is connected to the internal combustion engine 12 via a first heat medium flow path 32. The heat medium heated to a high temperature by the internal combustion engine 12 is sent to the heater 27 via the first heat medium flow path 32. The heater 27 releases heat to the surroundings. Air sent out by the blower 23 passes through the heater 27, and warm air is sent to the cabin C. The heater 27 is connected to a second refrigerant flow path 36 via a second heat medium flow path 33. That is, the heat medium from the heater 27 and the refrigerant from the radiator 16 join together and flow through the second refrigerant flow path 36 to reach the internal combustion engine 12.

[0025] The electric compressor 24 is disposed above the floor surface 19a (see FIG. 1) of the floor panel 19. Specifically, the electric compressor 24 is disposed above the upper ends of the front wheels 3. The electric compressor 24 may also be disposed above the upper end of a seat portion of the passenger seat 6 (see FIG. 1) that supports the passenger's buttocks from below.

[0026] 3 is a perspective view of the air conditioner 21 and other components of the vehicle in FIG. 1, viewed from the right rear. As shown in FIG. 3, the air conditioner 21 includes a heat exchange segment 41, a blower segment 42, an intake duct 43, and a discharge duct 44. The refrigerant inlet of the heat exchange segment 41 is connected to the condenser 25. The refrigerant outlet of the heat exchange segment 41 is connected to the electric compressor 24.

[0027] The heat exchange segment 41 has a housing 50 and an evaporator 22 housed in the housing 50. An outlet 50a is provided on the upper wall of the housing 50, through which the air cooled by the evaporator 22 flows out. A discharge duct 44 is fixed to the housing 50, which communicates with the outlet 50a and through which the air flowing out from the outlet 50a flows.

[0028] Specifically, the discharge duct 44 includes a first discharge duct 44A, a second discharge duct 44B, and a third discharge duct 44C. The first discharge duct 44A has a discharge port facing the cabin C through openings on both sides of the dashboard 9 (see FIG. 1) in the left-right direction of the vehicle. The second discharge duct 44B has a discharge port facing the cabin C through an opening in the center of the dashboard 9 in the left-right direction of the vehicle. The third discharge duct 44C has a discharge port facing the windshield that covers the cabin C from the front through an opening in the front part of the dashboard 9.

[0029] The blower segment 42 includes a housing 51, a blower vane 23a housed in the housing 51, and an electric motor 23b that drives the blower vane 23a. The internal space of the housing 51 of the blower segment 42 is in communication with the internal space of the housing 50 of the heat exchanger segment 41. The blower segment 42 takes in air from outside the vehicle into the housing 51 through the intake duct 43 as the blower vane 23a, which is driven by the electric motor 23b, rotates, and sends the air into the heat exchanger segment 41, where it passes through the carburetor 22.

[0030] The electric compressor 24 is disposed in front of the air conditioner 21. The dash panel 8, not shown in Fig. 3, is interposed between the air conditioner 21 and the electric compressor 24. The electric compressor 24 is disposed between the air conditioner 21 and the condenser 25 in the front-to-rear direction of the vehicle.

[0031] According to the configuration described above, the air conditioner 21, the condenser 25, the expansion valve 26, and the electric compressor 24 are all located forward of the dashboard 9, so that the first refrigerant flow path 28 connecting the evaporator 22 to the electric compressor 24 and the second refrigerant flow path 29 connecting the electric compressor 24 to the condenser 25 can be shortened. This allows the air conditioning system 20 mounted on the off-road vehicle 1 to be made compact as a whole. Furthermore, because the compressor 24 is electrically driven, the air conditioning system 20 can provide sufficient cooling capacity even when traveling at low speeds.

[0032] Since the air conditioning system 20 is entirely concentrated in an area forward of the dashboard 9, the overall size of the air conditioning system 20 mounted on the off-road vehicle 1 can be made compact. Since the electric compressor 24 is disposed at a location sufficiently distant from the internal combustion engine 12, the effects of vibration and heat from the internal combustion engine 12 on the electric compressor 24 can be reduced.

[0033] By disposing the electric compressor 24 in the front space S1, the accommodation space S2 between the dash panel 8 and the dashboard 9 is interposed between the occupants in the cabin C and the electric compressor 24, thereby reducing the operating noise of the electric compressor 24 transmitted to the occupants. In addition, because the electric compressor 24 is disposed in the front space S1 together with the radiator fan 17, it is possible to prevent the operating noise of the electric compressor 24 from being mixed in with the operating noise of the radiator fan 17 and causing discomfort to the occupants.

[0034] The fan wind shield 39 prevents the hot air sent from the radiator fan 17 from directly hitting the electric compressor 24, thereby suppressing a rise in temperature of the electric compressor 24. Furthermore, because the electric compressor 24 is disposed at a high position in the front space S1, it is possible to reduce the possibility of the electric compressor 24 becoming wet when the off-road vehicle 1 travels through a puddle.

[0035] Fig. 4 is a left side view of an off-road vehicle 101 showing a first modified example of the arrangement of the electric compressor 24. As shown in Fig. 4, in the off-road vehicle 101, the electric compressor 24 is arranged together with the air conditioner 21 in the accommodation space S2 between the dash panel 8 and the dashboard 9. The electric compressor 24 is arranged below the air conditioner 21. As a result, the electric compressor 24 is not arranged in the front space S1, which increases the degree of freedom in the arrangement of the components arranged in the front space S1.

[0036] 5 is a perspective view of the electric compressor 24 and soundproof structure 160 of FIG. 4. As shown in FIG. 5, the electric compressor 24 may be covered by the soundproof structure 160. The soundproof structure 160 may be, for example, a sound-absorbing box with a large number of projections and recesses on the surface facing the electric compressor 24. The soundproof structure 160 may also be a sound-insulating material that covers the electric compressor 24. The soundproof structure 160 may be applied to the electric compressor 24 arranged in the accommodation space S2, or may be applied to the electric compressor 24 arranged in the front space S1.

[0037] Fig. 6 is a plan view showing a second modified example of the arrangement of electric compressor 24. As shown in Fig. 6, when electric compressor 24 is arranged in storage space S2 defined between dash panel 8 and dashboard 9, electric compressor 24 may be arranged side by side with air conditioner 21 in the vehicle width direction. Electric compressor 24 may also be arranged at a height that overlaps with air conditioner 21 when viewed in the vehicle width direction.

[0038] Fig. 7 is a schematic diagram showing an electric compressor 124 of a first modified example. As shown in Fig. 7, the electric compressor 124 includes a refrigerant compressor 65 having a driven shaft 65a. The driven shaft 65a of the refrigerant compressor 65 is connected to the electric motor 23b of the blower 23. The electric motor 23b is connected to the blower vane 23a and the driven shaft 65a of the refrigerant compressor 65 so as to be used both to drive the blower vane 23a and the refrigerant compressor 65. In other words, the refrigerant compressor 65 and the electric motor 23b constitute the electric compressor 124.

[0039] Fig. 8 is a schematic diagram showing an electric compressor 224 of a second modified example. As shown in Fig. 8, the driven shaft 65a of the refrigerant compressor 65 is connected to the electric motor 17b of the radiator fan 17. The electric motor 17b is connected to the fan vane 17a and the driven shaft 65a of the refrigerant compressor 65 so as to be used both to drive the fan vane 17a and the refrigerant compressor 65. In other words, the refrigerant compressor 65 and the electric motor 17b constitute an electric compressor 124.

[0040] FIG. 9 is a left side view of an off-road vehicle 301 showing a first modified example of the arrangement of the radiator 16. As shown in FIG. 9, in the off-road vehicle 301, the radiator 16 connected to the internal combustion engine 12 is arranged rearward of the cabin C. Specifically, the radiator 16 is fixed to the rear of the cabin frame 2b. This allows the electric compressor 24 to be arranged sufficiently far from the radiator 16, thereby reducing the thermal effect of the radiator 16 on the electric compressor 24. Furthermore, the refrigerant flow path connecting the radiator 16 and the internal combustion engine 12 is shortened. The radiator 16 may also be arranged below the cargo bed 11.

[0041] FIG. 10 is a left side view of a main portion of an off-road vehicle 301 showing a first modified example of the arrangement of the condenser 25. As shown in FIG. 10, in the off-road vehicle 301, the condenser 25 is arranged outside the radiator 16 in a direction perpendicular to the vehicle front-rear direction. Specifically, the condenser 25 is arranged rearward and above the radiator 16. The condenser 25 is arranged along the inner surface of the front cover 5. The front cover 5 has an opening 5a that guides the traveling wind to the radiator 16, and an opening 5b that guides the traveling wind to the condenser 25. With this configuration, the influence between the condenser 25 and the radiator 16 is reduced, and both the radiator 16 and the condenser 25 can be air-cooled in an appropriate manner.

[0042] FIG. 11 is a plan view of a main portion of an off-road vehicle 401 showing a second modified example of the arrangement of the condenser 25. As shown in FIG. 11, in the off-road vehicle 401, the condenser 25 is arranged outside the radiator 16 in a direction perpendicular to the vehicle's longitudinal direction. Specifically, the condenser 25 is arranged outward of the radiator 16 in the vehicle width direction. The condenser 25 is arranged along the inner surface of the front cover 5. The front cover 5 has an opening 5a that guides the traveling wind to the radiator 16 and an opening 5c ​​that guides the traveling wind to the condenser 25. With this configuration, the influence between the condenser 25 and the radiator 16 is reduced, and both the radiator 16 and the condenser 25 can be air-cooled in an optimal manner.

[0043] Fig. 12 is a left side view of an off-road vehicle 501 showing a modified arrangement of the compressor. As shown in Fig. 12, at least a portion of the internal combustion engine 12 is disposed vertically below the cargo bed 11 in a side view of the vehicle. At least a portion of the electric compressor 24 is disposed vertically below the passenger seat 6 in a side view of the vehicle. If the passenger seat 6 is slidable in the fore-and-aft direction of the vehicle, at least a portion of the electric compressor 24 is disposed vertically below the passenger seat 6 in a side view of the vehicle over the entire sliding range of the passenger seat 6. The electric compressor 24 is disposed in front of the internal combustion engine 12.

[0044] According to this configuration, the electric compressor 24 is disposed away from the internal combustion engine 12 in a side view of the vehicle, thereby reducing the influence of the internal combustion engine 12 on the electric compressor 24. Furthermore, because the compressor 24 is electrically driven, the degree of freedom in arranging the compressor 24 in the space below the passenger seat 6 can be increased.
