Description

[Technical Field]

[0001] The present invention relates to an integrated package for a vehicle housed in a motor room, which is a space separated from a passenger compartment. [Background technology]

[0002] 2. Description of the Related Art Vehicle air conditioning systems have been used to cool and heat the interior of a vehicle. Technologies relating to such vehicle air conditioning systems are disclosed in, for example, Patent Document 1 and Patent Document 2, the sources of which are listed below.

[0003] Patent Document 1 describes a vehicle air conditioning system. This vehicle air conditioning system includes a temperature adjustment unit that adjusts the temperature of air blown into the vehicle cabin, and a plurality of air distribution ducts connected to the temperature adjustment unit that guide the temperature-adjusted air to predetermined locations within the vehicle cabin. The temperature adjustment unit is located in an outdoor space separated from the vehicle cabin by a partition wall, together with a drive device that constitutes a power source for driving.

[0004] Patent Document 2 describes a vehicle air conditioning unit. This vehicle air conditioning unit includes an evaporator and an inner condenser, which are arranged forward of the dash panel so that they overlap each other when viewed in the vehicle's longitudinal direction. This allows the evaporator and the inner condenser to be crushed and deformed by the load input during a frontal collision, and to be used as collision energy absorbing members during a frontal collision. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-150033 [Patent Document 2] Patent Publication No. 2021-59290 Summary of the Invention [Problem to be solved by the invention]

[0006] The vehicle air conditioning system described in Patent Document 1 has a temperature control unit located in an outdoor space separated from the vehicle interior by a partition wall, but requires a dedicated mount to support the temperature control unit on the vehicle body and a vibration absorption mechanism to absorb vibrations from the surroundings. Furthermore, since the temperature control unit is configured separately from the drive equipment, it takes time to assemble it into the vehicle body. Furthermore, the vehicle air conditioning unit described in Patent Document 2 has a drive unit and power module located further forward on the vehicle body than the dash panel, which could expose high-voltage components in the drive unit and power module in the event of a frontal collision.

[0007] Therefore, there is a demand for a vehicle air conditioning system that can be easily installed on the vehicle body and that does not expose high-voltage components. [Means for solving the problem]

[0008] The characteristic configuration of the integrated vehicle package of the present invention is that it is a vehicle integrated package housed in a motor room, which is a space partitioned from a passenger compartment where people can ride, and is equipped with an air conditioning unit that heats and cools the passenger compartment, and a power supply module that is integrated with the air conditioning unit and supplies power to a driving unit that drives the vehicle, and at least a portion of the air conditioning unit is located forward of the power supply module in the direction of travel of the vehicle.

[0009] With this characteristic configuration, the air conditioning unit and power supply module can be installed as a single unit on the vehicle, simplifying installation on the vehicle body. Furthermore, since the air conditioning unit and power supply module can be positioned close to each other, the heat from the power supply module can be used efficiently for air conditioning, improving electricity consumption. Furthermore, since at least a portion of the air conditioning unit is located in front of the power supply module along the vehicle's direction of travel, the high-voltage components of the power supply module are not exposed, even in the event of a frontal collision.

[0010] Another characteristic feature of the vehicle integrated package of the present invention is that it is a vehicle integrated package housed in a motor room, which is a space separated from a passenger compartment, and is equipped with an air conditioning unit that heats and cools the passenger compartment, and a driving drive unit that is integrated with the air conditioning unit and drives the vehicle, and at least a portion of the air conditioning unit is located forward of the driving drive unit in the direction of travel of the vehicle.

[0011] With this characteristic configuration, the air conditioning unit and the traveling drive unit can be assembled to the vehicle as a single unit, making assembly to the vehicle body easy. Furthermore, since the air conditioning unit and the traveling drive unit can be positioned close to each other, heat from the traveling drive unit can be efficiently used for air conditioning, improving power consumption. Furthermore, since at least a portion of the air conditioning unit is located in front of the traveling drive unit along the vehicle's direction of travel, high-voltage components of the traveling drive unit are not exposed even in the event of a frontal collision.

[0012] Furthermore, another characteristic configuration of the vehicle integrated package of the present invention is that it is a vehicle integrated package housed in a motor room, which is a space partitioned from a passenger compartment, and comprises an air conditioning unit for heating and cooling the passenger compartment, and a vehicle drive device integrated with the air conditioning unit and having a driving drive unit for driving the vehicle and a power supply module for supplying power to the driving drive unit, and at least a portion of the air conditioning unit is located forward of the vehicle drive device in the direction of travel of the vehicle.

[0013] With this configuration, the air conditioning unit and the vehicle drive device can be installed integrally on the vehicle, simplifying installation on the vehicle body. Furthermore, since the air conditioning unit and the vehicle drive device can be positioned close to each other, heat from the vehicle drive device can be efficiently utilized for air conditioning, improving power consumption. Furthermore, since at least a portion of the air conditioning unit is located on the front side of the vehicle drive device along the vehicle's traveling direction, high-voltage components of the vehicle drive device are not exposed even in the event of a frontal collision.

[0015] The vehicle integrated package according to the present invention is configured to increase the vehicle interior space and prevent high-voltage components from being exposed even during a frontal collision. The vehicle integrated package 300 according to this embodiment will be described below. However, the vehicle integrated package 300 is not limited to the following embodiment, and various modifications are possible without departing from the spirit and scope of the invention.

[0016] 1 shows a vehicle 2 equipped with a vehicle integrated package 300. In FIG. 1, the front side of the vehicle 2 in the traveling direction is indicated by "F" and the rear side of the vehicle 2 in the traveling direction is indicated by "B."

[0017] A battery 4 that stores power used for traveling the vehicle 2 is provided in the bottom 2A of the vehicle 2. The battery 4 is covered with a battery cover 4A facing the road surface 200 to prevent damage from pebbles and the like that may be kicked up while the vehicle 2 is traveling. A vehicle compartment 3 in which passengers can ride is provided in the vehicle body 8, and the vehicle compartment 3 is separated from a motor room 7 by a partition wall 6a of the dashboard 6. Therefore, the vehicle integrated package 300 is housed in the motor room 7, which is a space partitioned from the vehicle compartment 3 and is located forward F of the partition wall 6a of the dashboard 6 in the direction of travel.

[0018] Fig. 2 shows an exploded perspective view of the vehicle drive device 1. In Fig. 2, in addition to "F" indicating the front side in the traveling direction of the vehicle 2 and "B" indicating the rear side in the traveling direction of the vehicle 2, "R" indicates the right side when looking at the front side F in the traveling direction of the vehicle 2, and "L" indicates the left side when looking at the front side F in the traveling direction of the vehicle 2.

[0019] The vehicle drive device 1 of this embodiment has a traveling drive unit 10 that drives the vehicle 2, and a power supply module 9 that supplies power to the traveling drive unit 10. The power supply module 9 is provided in an upper part of the vehicle drive device 1, and the traveling drive unit 10 is provided in a lower part of the vehicle drive device 1. Therefore, in this embodiment, the power supply module 9 and the traveling drive unit 10 are provided vertically side by side in a direction perpendicular to both the traveling direction and the vehicle width direction of the vehicle 2 (lined up vertically).

[0020] As shown in FIG. 2, the power supply module 9 is configured by accommodating an OBC (On Board Charger) board 91, a motor drive board 92, and a control board 93 that controls the OBC board 91 and the motor drive board 92 in a housing 100. The power supply module 9 has a first space 101. The OBC board 91, the motor drive board 92, and the control board 93 are each separate and distinct boards that are accommodated in the first space 101 in parallel orientations. Hereinafter, the direction perpendicular to the plate surface of the OBC board 91 will be referred to as the "vertical direction," the direction in which the control board 93 is viewed from the OBC board 91 and the motor drive board 92 along this vertical direction will be referred to as the "upper direction," "upper side," etc., and the direction in which the OBC board 91 and the motor drive board 92 are viewed from the control board 93 will be referred to as the "lower direction," "lower side," etc.

[0021] In this embodiment, the OBC board 91 and the motor drive board 92 are arranged side by side in the horizontal direction. The control board 93 is arranged so as to overlap the OBC board 91 and the motor drive board 92 when viewed in the vertical direction (vertical view). The connection between the OBC board 91 and the control board 93, and the connection between the motor drive board 92 and the control board 93, are made via board-to-board connectors (not shown).

[0022] At least an inverter and a converter are mounted on the OBC board 91. The inverter is supplied with AC power consisting of AC voltage from a commercial power source and converts the AC power into DC power including DC voltage. The converter is supplied with DC power generated by the inverter and boosts the voltage value of the DC voltage that constitutes the DC power supplied from the inverter to a DC voltage of a voltage value required to charge the battery 4. The OBC board 91 is also provided with a capacitor 98 that smoothes the DC voltage converted by the inverter and a capacitor 99 that smoothes the DC voltage converted by the converter.

[0023] The motor drive board 92 is mounted with at least a drive inverter that controls the drive current that drives the motor 16. The control board 93 is also mounted with a control unit that controls the inverter and converter.

[0024] The OBC substrate 91, the motor drive substrate 92, the capacitor 98, and the capacitor 99 are provided opposite a cooling plate 94 through which coolant flows from a coolant module C, which will be described later. This makes it possible to cool the OBC substrate 91, the motor drive substrate 92, the capacitor 98, and the capacitor 99.

[0025] The traveling drive unit 10 includes at least a motor 16 that outputs power that enables the vehicle 2 to travel. The motor 16 is driven by a motor drive board 92. The vehicle 2 travels based on the rotational force output from the motor 16. In this embodiment, the traveling drive unit 10 also includes a gear mechanism 17, which will be described later.

[0026] The housing 100 has a first space 101 and a second space 102 and a third space 103 that are partitioned from each other. The second space 102 and the third space 103 are located below the first space 101. The second space 102 houses a motor 16, and the third space 103 houses a gear mechanism 17 that reduces the rotation of the motor 16 and outputs it. The housing 100 has an opening 100a above the first space 101, and the OBC board 91, motor drive board 92, and control board 93 are housed in the first space 101 through the opening 100a. The opening 100a is closed by a lid 114, making the first space 101 a closed space.

[0027] The second space 102 accommodates the motor 16 from the side and is closed by a motor cover 115 fastened with bolts (not shown) to form a closed space. Motor shafts 16a extend from the motor 16 on both sides along the rotation axis, with one motor shaft 16a penetrating the motor cover 115 and exposed to the outside of the housing 100. The other motor shaft 16a penetrates into the third space 103. The third space 103 accommodates a gear mechanism 17 from the side and is closed by a gear cover 116 fastened with bolts (not shown) to form a closed space. The other motor shaft 16a extending from the second space 102 is connected to the gear mechanism 17, and the rotation of the motor 16 is input via the motor shaft 16a. The gear mechanism 17 reduces the rotation of the motor 16 and outputs it from a gear shaft 17a. The gear shaft 17a penetrates the gear cover 116 and is exposed to the outside of the housing 100.

[0028] FIG. 3 shows the circuit configuration of an air conditioning system A equipped with an air conditioning unit D. The air conditioning system A is mounted on a vehicle 2 and includes a refrigerant module B, a coolant module C, and an air conditioning unit D. The refrigerant module B is provided with a refrigerant manifold B2 including a refrigerant flow path B1 through which the refrigerant flows. The coolant module C is provided with a coolant manifold C2 including a coolant flow path C1 through which the coolant flows. Here, the manifold is a flow path housing formed by laminating and sealing a plate member on a housing main body in which the refrigerant flow path B1 and the coolant flow path C1 are engraved. The flow path housing is formed from a metal material with high thermal conductivity, including aluminum.

[0029] A refrigerant such as hydrofluorocarbon (HFC) or hydrofluoroolefin (HFO) flows through the refrigerant flow path B1, and a coolant such as antifreeze or long-life coolant whose main ingredient is ethylene glycol, or a coolant composed of insulating oil such as paraffin, flows through the coolant flow path C1.

[0030] 3, the refrigerant flow path B1 is configured to circulate the refrigerant through an accumulator B10, a compressor B11 as a compressor, a water-cooled condenser B12 as a condenser, a first expansion valve B13 as an expansion valve, and an evaporator B14 as an evaporator. The refrigerant is also configured to circulate through a second expansion valve B15 and a chiller B16 as an evaporator, bypassing the first expansion valve B13 and the evaporator B14.

[0031] The accumulator B10 stores liquid refrigerant and separates the stored refrigerant into gas and liquid. The gaseous refrigerant separated by the accumulator B10 flows through a first refrigerant passage B21 and is sent to the compressor B11.

[0032] The compressor B11 compresses the refrigerant from the accumulator B10. This causes the refrigerant to become a high-temperature compressed gas. The compressor B11 sends this high-temperature compressed gas to the water-cooled condenser B12 via the second refrigerant path B22. Therefore, the compressor B11 pressure-feeds the refrigerant from the accumulator B10 to the water-cooled condenser B12.

[0033] The water-cooled condenser B12 is circulated with refrigerant that has passed through the compressor B11. The water-cooled condenser B12 is configured so that the coolant flows in through a first coolant flow path C31 and flows out through a second coolant flow path C32. The first coolant flow path C31 and the second coolant flow path C32 are configured separately from the second refrigerant flow path B22. The refrigerant from the second refrigerant flow path B22 is condensed and liquefied as heat is absorbed by the coolant. The liquefied refrigerant is sent to a third refrigerant flow path B23. Like the second refrigerant flow path B22, this third refrigerant flow path B23 is also configured separately from the first coolant flow path C31 and the second coolant flow path C32. The third refrigerant flow path B23 is branched, one side communicating with the first expansion valve B13 and the other side communicating with the second expansion valve B15.

[0034] The first expansion valve B13 has a flow path area that is suddenly narrower than that of the third refrigerant path B23, allowing only a small amount of refrigerant to flow through. This reduces the pressure of the refrigerant, which in turn reduces the temperature of the refrigerant and turns it into a low-temperature, low-pressure mist. The mist refrigerant is then sent to the fourth refrigerant path B24.

[0035] The evaporator B14 circulates a refrigerant through a fourth refrigerant passage B24. The refrigerant expanded by the first expansion valve B13 and converted into a low-temperature, low-pressure atomized refrigerant flows through the fourth refrigerant passage B24, and this refrigerant is sent to the evaporator B14. Outside air drawn in by the blower D51 is introduced into the evaporator B14. As a result, the atomized refrigerant absorbs heat from the outside air and evaporates. The evaporated refrigerant flows through a fifth refrigerant passage B25 and a check valve E1 to the accumulator B10.

[0036] Similarly to the first expansion valve B13, the second expansion valve B15 also has a flow path area that narrows sharply compared to the third refrigerant path B23, allowing only a small amount of refrigerant to flow through. This reduces the pressure of the refrigerant, which in turn reduces the temperature of the refrigerant and turns it into a low-temperature, low-pressure mist. The mist refrigerant is then sent to the sixth refrigerant path B26.

[0037] A refrigerant flows through the chiller B16 via a sixth refrigerant passage B26. The sixth refrigerant passage B26 is filled with low-temperature, low-pressure atomized refrigerant that has been expanded by the second expansion valve B15, and this refrigerant is sent to the chiller B16. The chiller B16 is configured so that the liquid coolant flows in through a third liquid coolant passage C33 and flows out through a fourth liquid coolant passage C34. The third liquid coolant passage C33 and the fourth liquid coolant passage C34 are configured separately from the sixth refrigerant passage B26. In the chiller B16, the atomized refrigerant absorbs heat from the liquid coolant and evaporates. The evaporated refrigerant flows through a fifth refrigerant passage B25 to the accumulator B10.

[0038] The coolant flow path C1 carries coolant that exchanges heat with the refrigerant in the water-cooled condenser B12 and the chiller B16. The coolant module C is configured to allow the coolant to flow to the water-cooled condenser B12 and the chiller B16 via the coolant flow path C1 using a pump (not shown).

[0039] As described above, the coolant from the coolant module C is configured to flow through the cooling plate 94 (not shown) provided in the power supply module 9 of the vehicle drive device 1.

[0040] The air conditioning unit D includes a blower D51, an evaporator B14, and a heater core D52, and is capable of heating and cooling the passenger compartment 3. The blower D51 draws in outside air and sends the drawn outside air to the evaporator B14.

[0041] The evaporator B14 functions as a heat exchanger that exchanges heat between air (an example of a "first fluid") and a refrigerant (an example of a "second fluid") to cool or heat the passenger compartment 3. The air is outside air drawn in by the blower D51. As described above, the refrigerant is introduced into the evaporator B14 via the fourth refrigerant passage B24. Therefore, in the evaporator B14, heat exchange occurs between the outside air sent from the blower D51 and the refrigerant introduced via the fourth refrigerant passage B24.

[0042] The heater core D52 is warmed up by a heater (not shown) and / or heated coolant. The warmed heater core D52 exchanges heat with outside air sent from the blower D51.

[0043] With the above-described configuration, when outside air is cooled in the evaporator B14, cool air is introduced into the passenger compartment 3 through the duct 5, and when outside air is heated in the heater core D52, warm air is introduced into the passenger compartment 3 through the duct 5. This makes it possible to cool or heat the passenger compartment 3. Note that in addition to the duct 5, the vehicle 2 may be provided with other ducts (not shown) so that the air can be introduced in front of the driver, at the driver's feet, or to the windshield.

[0044] FIG. 4 shows an example of the arrangement of a vehicle integrated package 300. In the example of FIG. 4, the power supply module 9 is integrated with the air conditioning unit D. Therefore, the air conditioning system A having the air conditioning unit D is housed in the motor room 7 in a state where it is integrated with the power supply module 9. Here, "integration" means a state in which the air conditioning system A is fixed to the vehicle drive device 1 with bolts or the like. In this case, it is also possible to fix the vehicle drive device 1 and the air conditioning system A by sandwiching an elastic member (e.g., a rubber member) between them. Note that this "integration" also includes using the same material for the vehicle drive device 1 and the air conditioning system A and forming both in the same case.

[0045] 4, at least a portion of the air conditioning unit D is provided forward of the power supply module 9 along the traveling direction of the vehicle 2. Specifically, as shown in FIG. 4, the blower D51, the evaporator B14, and the heater core D52 are provided in a region in front of the air conditioning unit D along the traveling direction of the vehicle 2, and the power supply module 9 is provided behind the blower D51, the evaporator B14, and the heater core D52 along the traveling direction of the vehicle 2.

[0046] In this way, by providing the blower D51, evaporator B14, and heater core D52 on the front side of the power supply module 9 along the traveling direction of the vehicle 2, it is possible to provide the power supply module 9, to which high voltage is applied, on the rear side of the motor room 7 along the traveling direction of the vehicle 2. Therefore, even if the air conditioning unit D is damaged in a frontal collision of the vehicle 2, the power supply module 9 can be protected by the blower D51, evaporator B14, and heater core D52, and the high-voltage components of the power supply module 9 can be prevented from being exposed to the outside of the vehicle.

[0047] Of course, as shown in Figure 5, when integrating the power supply module 9 with the air conditioning unit D, it is also possible to configure the power supply module 9 so that the entire air conditioning unit D is located at the front along the traveling direction of the vehicle 2. In this case, too, the power supply module 9 to which high voltage is applied can be provided at the rear along the traveling direction of the vehicle 2 in the motor room 7. Therefore, even if the air conditioning unit D is damaged in a frontal collision of the vehicle 2, the power supply module 9 can be protected by the entire air conditioning unit D, and the high-voltage components of the power supply module 9 can be prevented from being exposed.

[0048] Other Embodiments Next, other embodiments of the vehicle integrated package 300 will be described.

[0049] In the above embodiment, it has been described that the power supply module 9 is integrated with the air conditioning unit D, and at least a portion of the air conditioning unit D is provided forward of the power supply module 9 along the traveling direction of the vehicle 2. However, the traveling drive unit 10 may be integrated with the air conditioning unit D, and at least a portion of the air conditioning unit D may be provided forward of the traveling drive unit 10 along the traveling direction of the vehicle 2.

[0050] An example of the arrangement of such a vehicle integrated package 300 is shown in Figure 6. As shown in Figure 6, when integrating the traveling drive unit 10 with the air conditioning unit D, it is also possible to configure the traveling drive unit 10 so that the entire air conditioning unit D is located on the front side along the traveling direction of the vehicle 2. In this case, the power supply module 9 to which high voltage is applied and the traveling drive unit 10 can be provided on the rear side along the traveling direction of the vehicle 2 in the motor room 7. Therefore, even if the air conditioning unit D is damaged in a frontal collision of the vehicle 2, the power supply module 9 and the traveling drive unit 10 can be protected by the entire air conditioning unit D and will not be exposed to the outside of the vehicle.

[0051] Alternatively, as shown in Figure 7, when integrating the travel drive unit 10 with the air conditioning unit D, it is also possible to configure the travel drive unit 10 so that the entire air conditioning unit D is located on the front side along the traveling direction of the vehicle 2. In this case, the travel drive unit 10 can be provided on the rear side along the traveling direction of the vehicle 2 in the motor room 7. Therefore, even if the air conditioning unit D is damaged in a frontal collision of the vehicle 2, the travel drive unit 10 can be protected by the entire air conditioning unit D and will not be exposed to the outside of the vehicle.

[0052] In addition, the vehicle drive device 1 having the traveling drive unit 10 and the power supply module 9 may be integrated with the air conditioning unit D, and at least a part of the air conditioning unit D may be located forward of the vehicle drive device 1 along the direction of travel of the vehicle 2.

[0053] An example of the layout of such a vehicle integrated package 300 is shown in Figure 8. As shown in Figure 8, when integrating a vehicle drive device 1 having a driving unit 10 and a power supply module 9 with an air conditioning unit D, it is also possible to configure the driving unit 10 so that the blower D51, evaporator B14, and heater core D52 are located on the front side along the traveling direction of the vehicle 2. In this case, the power supply module 9 to which high voltage is applied and the driving unit 10 can be provided on the rear side along the traveling direction of the vehicle 2 in the motor room 7. Therefore, even if the air conditioning unit D is damaged in a frontal collision of the vehicle 2, the driving unit 10 can be protected by the entire air conditioning unit D and will not be exposed to the outside of the vehicle.

[0054] Alternatively, as shown in FIG. 9, when integrating a vehicle drive device 1 having a traveling drive unit 10 and a power supply module 9 with an air conditioning unit D, it is also possible to configure the power supply module 9 and traveling drive unit 10 so that the blower D51, evaporator B14, and heater core D52 are located in front of the vehicle 2 in the traveling direction. In this case, the power supply module 9 and traveling drive unit 10 can be provided in the motor room 7 at the rear of the vehicle 2 in the traveling direction. Therefore, even if the air conditioning unit D is damaged in a frontal collision of the vehicle 2, the power supply module 9 and traveling drive unit 10 can be protected by the blower D51, evaporator B14, and heater core D52 and will not be exposed to the outside of the vehicle.

[0055] In the above embodiment, the evaporator B14 of the air conditioning unit D is described as being provided in the front region of the air conditioning unit D, but the evaporator B14 of the air conditioning unit D may also be provided in the rear region of the air conditioning unit D.

[0056] [Summary of the above embodiment] The vehicle integrated package 300 described above will now be outlined.

[0057] (1) The vehicle integrated package 300 is housed in a motor room 7, which is a space partitioned from a passenger compartment 3 where people can ride, and includes an air conditioning unit D for heating and cooling the passenger compartment 3, and a power supply module 9 integrated with the air conditioning unit D for supplying power to a driving unit 10 that drives the vehicle 2, with at least a portion of the air conditioning unit D being located forward of the power supply module 9 along the direction of travel of the vehicle 2.

[0058] According to this configuration, the air conditioning unit D and the power supply module 9 can be assembled as a single unit to the vehicle 2, which simplifies assembly to the vehicle body 8. Furthermore, the air conditioning unit D and the power supply module 9 can be arranged close to each other, which allows the heat of the power supply module 9 to be used efficiently for air conditioning, thereby improving electricity consumption. Furthermore, at least a portion of the air conditioning unit D is provided in front of the power supply module 9 along the direction of travel of the vehicle 2, which prevents the high-voltage components of the power supply module 9 from being exposed even in the event of a frontal collision of the vehicle 2.

[0059] (2) The vehicle integrated package 300 is housed in a motor room 7, which is a space separated from a passenger compartment 3 where passengers can ride, and includes an air conditioning unit D that heats and cools the passenger compartment 3, and a driving unit 10 that is integrated with the air conditioning unit D and drives the vehicle 2, with at least a portion of the air conditioning unit D being located forward of the driving unit 10 along the direction of travel of the vehicle 2.

[0060] According to this configuration, the air conditioning unit D and the traveling drive unit 10 can be assembled integrally to the vehicle 2, which simplifies assembly to the vehicle body 8. Furthermore, since the air conditioning unit D and the traveling drive unit 10 can be arranged close to each other, the heat of the traveling drive unit 10 can be used efficiently for air conditioning, thereby improving power consumption. Furthermore, since at least a portion of the air conditioning unit D is provided in front of the traveling drive unit 10 along the traveling direction of the vehicle 2, high-voltage components of the traveling drive unit 10 can be prevented from being exposed even in the event of a frontal collision of the vehicle 2.

[0061] (3) Furthermore, the vehicle integrated package 300 is housed in a motor room 7, which is a space partitioned from a passenger compartment 3 where people can ride, and includes an air conditioning unit D for heating and cooling the passenger compartment 3, and a vehicle drive device 1 integrated with the air conditioning unit D and having a traveling drive unit 10 for driving the vehicle 2 and a power supply module 9 for supplying power to the traveling drive unit 10, and at least a portion of the air conditioning unit D is located forward of the vehicle drive device 1 along the direction of travel of the vehicle 2.

[0062] According to this configuration, the air conditioning unit D and the vehicle drive device 1 can be assembled integrally to the vehicle 2, which simplifies assembly to the vehicle body 8. Furthermore, since the air conditioning unit D and the vehicle drive device 1 can be arranged close to each other, the heat of the vehicle drive device 1 can be used efficiently for air conditioning, thereby improving power consumption. Furthermore, since at least a portion of the air conditioning unit D is provided on the front side of the vehicle drive device 1 along the traveling direction of the vehicle 2, high-voltage components of the vehicle drive device 1 can be prevented from being exposed even in the event of a frontal collision of the vehicle 2.

[0063] (4) In the vehicle integrated package 300 described in any one of (1) to (3), the air conditioning unit D has an evaporator B14 (heat exchanger) that performs heat exchange between air (first fluid) and a refrigerant (second fluid), and it is preferable that the evaporator B14 is provided in a front region of the air conditioning unit D.

[0064] According to this configuration, the evaporator B14 is provided in the front region of the air conditioning unit D, so that the evaporator B14 can function as a buffer even if the vehicle 2 is hit from the front. This makes it possible to protect the power supply module 9 and / or the travel drive unit 10 provided behind the evaporator B14 in the traveling direction of the vehicle 2. [Industrial Applicability]

[0065] The technology disclosed herein can be used in an integrated vehicle package housed in a motor room, which is a space separated from the passenger compartment. [Explanation of symbols]
