Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, when the casing that houses both the rotating electric machine and the inverter device becomes large, it may be difficult to layout in-vehicle components that are not directly connected to the drive device. This specification provides a technology for improving the degree of freedom in the layout of in-vehicle components.

Means for Solving the Problems

[0005] The electric vehicle disclosed in this specification includes a drive device that drives the drive wheels of the electric vehicle, and in-vehicle components that are not directly connected to the drive device. The drive device includes an electric motor, a first casing that houses the electric motor, a power conversion device electrically connected to the electric motor, and a second casing that is located above or below the first casing, fixed to the first casing, and houses the power conversion device. A housing space that penetrates the drive device in the vehicle longitudinal direction is provided between the first casing and the second casing, and a part of the in-vehicle components is located in the housing space.

[0006] In the electric vehicle described above, a part of the in-vehicle components that are not directly connected to the drive device is located in the accommodation space positioned between the first casing and the second casing. Therefore, the degree of freedom in the layout of the in-vehicle components mounted on the electric vehicle, including the drive device, can be improved.

[0007] Details and further improvements of the technology disclosed in this specification will be described in the following "Mode for Carrying Out the Invention".

Mode for Carrying Out the Invention

[0009] In one embodiment of the present technology, the first casing may include a housing that extends in a cylindrical shape from a first end face to a second end face, a first cover attached to the first end face of the housing, and a second cover attached to the second end face of the housing. In that case, the second casing may be fixed to the first cover and the second cover.

[0010] According to such a configuration, a relatively wide accommodation space can be provided between the housing that extends in a cylindrical shape and the second casing. Thereby, it becomes possible to arrange some or all of various types of in-vehicle components in the accommodation space.

[0011] In one embodiment of the present technology, the first cover may have a first stay extending toward the second casing, and the second cover may have a second stay extending toward the second casing. In that case, the second casing may be fixed to the first stay and the second stay. However, in another embodiment, the second casing may include a first stay extending toward the first cover and a second stay extending toward the second cover.

[0012] In one embodiment of the present technology, the second casing may be located above the first casing. However, in another embodiment, the second casing may be located below the first casing.

[0013] In one embodiment of the present technology, the drive device may further include a transmission mechanism mechanically connected to the electric motor, and a third casing that houses the transmission mechanism. In that case, the third casing may be adjacent to the first casing above or below the second casing. And a part of the accommodation space may be located between the second casing and the third casing.

[0014] According to such a configuration, a relatively wide accommodation space can be provided not only between the first casing and the second casing but also between the second casing and the third casing. Thereby, some or all of various types of in-vehicle components can be arranged in the accommodation space.

[0015] In one embodiment of the present technology, the third casing may be located in front of the vehicle with respect to the first casing. In that case, the first casing and the third casing may be arranged along a direction of displacement downward as going forward in the vehicle front direction. However, in another embodiment, the first casing and the third casing may be arranged along a direction parallel to the vehicle longitudinal direction.

[0016] In one embodiment of the present technology, the in-vehicle component may include a steering shaft that passes through the accommodation space in the vehicle front-rear direction.

[0017] According to such a configuration, the degree of freedom in the layout of the steering shaft can be improved.

[0018] In one embodiment of the present technology, the electric vehicle further includes a steering wheel that is located behind the driving device in the vehicle, is connected to the rear end of the steering shaft, and is operated by a driver, and a steering gear that is located in front of the driving device in the vehicle, is connected to the front end of the steering shaft, and changes the steering angle of the driving wheels in response to the rotation of the steering wheel.

[0019] According to such a configuration, the steering gear for changing the steering angle of the driving wheels can be arranged in front of the driving device having a relatively large mass. Thereby, compared with the configuration in which the driving device is arranged in front of the steering gear, the steering performance of the electric vehicle can be improved.

[0020] In one embodiment of the present technology, the in-vehicle component may include a heat medium pipe that passes through the accommodation space in the vehicle front-rear direction and is connected to an air conditioner that air-conditions the passenger compartment.

[0021] According to such a configuration, the degree of freedom in the layout of the air conditioner and the heat medium pipe can be improved.

[0022] In one embodiment of the present technology, the electric vehicle further includes a battery that is located behind the driving device in the vehicle and supplies power to the motor of the driving device, and a charging inlet that is located in front of the driving device in the vehicle and is detachably connected to an external power source. In that case, the in-vehicle component may include a power cable that passes through the accommodation space in the vehicle front-rear direction and electrically connects the battery and the charging inlet.

[0023] With such a configuration, the degree of freedom in the layout of the charging inlet and the power cable can be improved.

[0024] (Example) FIG. 1 shows a block diagram of the electric vehicle 10 of the example as viewed from above. In this specification, the front of the electric vehicle 10 (i.e., above the paper surface of FIG. 1) may be simply referred to as "front", and the opposite side may be simply referred to as "rear". Further, the left side of the electric vehicle 10 (i.e., the left side of the paper surface of FIG. 1) may be simply referred to as "left", and the opposite side may be simply referred to as "right". Also, the upper side of the electric vehicle 10 (i.e., the front direction of the paper surface of FIG. 1) may be simply referred to as "up", and the opposite side may be simply referred to as "down".

[0025] The electric vehicle 10 includes a vehicle body 2, an instrument panel 3, a pair of left and right front wheels 4R and 4L, a pair of left and right rear wheels 5R and 5L, a front shaft 14, a rear shaft 15, a drive device 20, a battery unit 40, a steering unit 50, and an air conditioning unit 60. The electric vehicle 10 travels by driving a pair of left and right front wheels 4R and 4L using the drive device 20. Note that the "electric vehicle" in this specification includes, for example, a rechargeable electric vehicle charged by an external power source, a fuel cell vehicle using a fuel cell as a power source, and a hybrid vehicle having an engine. Hereinafter, the description of "a pair of left and right" may be simply described as "a pair".

[0026] The drive device 20 includes a motor unit 30, an inverter unit 70, and a transmission mechanism unit 80. The drive device 20 drives a pair of front wheels 4R and 4L via the front shaft 14. That is, in this embodiment, the pair of front wheels 4R and 4L are the drive wheels of the electric vehicle 10. In a modified example, the pair of rear wheels 5R and 5L may be the drive wheels of the electric vehicle 10, or the pair of front wheels 4R and 4L and the pair of rear wheels 5R and 5L may be the drive wheels of the electric vehicle 10.

[0027] The battery unit 40 includes a battery pack 42, a power cable 44, and a charging inlet 46. The battery unit 40 supplies the charging power of the external power source 7 to the battery pack 42. The battery pack 42 is disposed below the floor panel (not shown) of the electric vehicle 10. The battery pack 42 incorporates, for example, lithium-ion battery cells. In a modified example, the battery pack 42 may incorporate another secondary battery cell (nickel-metal hydride battery cell, all-solid-state battery cell). The charging inlet 46 is exposed at the front end of the electric vehicle 10. The charging inlet 46 is electrically connected to the external power source 7 via an external cable 8. The external cable 8 is detachably connected to the charging inlet 46. That is, the charging inlet 46 is detachably connected to the external power source 7. The power cable 44 extends in the vehicle longitudinal direction and electrically connects the charging inlet 46 and the battery pack 42. That is, although the power cable 44 is connected to the drive device 20 via at least the battery pack 42, the vehicle body 2, etc., it is not directly connected to the drive device 20.

[0028] The steering unit 50 changes the traveling direction of the electric vehicle 10 according to the operation of the driver. The steering unit 50 includes a steering wheel 52, a steering shaft 54, a steering gearbox 56, and a steering rod 58. The steering wheel 52 is connected to the rear end of the steering shaft 54 and is a handle operated by the driver. The steering shaft 54 extends in the vehicle longitudinal direction and mechanically connects the steering wheel 52 and the steering gearbox 56. That is, although the steering shaft 54 is connected to the drive device 20 via at least the steering rod 58 and the front shaft 14, it is not directly connected to the drive device 20. The steering gearbox 56 includes a plurality of steering gears. The steering rod 58 includes a plurality of rods and ball joints. When the steering wheel 52 is operated, the steering gears of the steering gearbox 56 rotate via the steering shaft 54. As a result, the steering rod 58 is displaced to change the steering angles of the pair of front wheels 4R and 4L. Thereby, the traveling direction of the electric vehicle 10 changes.

[0029] As shown in FIG. 1, the steering gearbox 56 is located in front of the drive device 20. The drive device 20 has a relatively large mass. In the electric vehicle 10 of the present embodiment, the drive device 20 is located closer to the center of the electric vehicle 10 than the steering gearbox 56 in the vehicle longitudinal direction. For this reason, compared with the configuration in which the drive device 20 is located in front of the steering gearbox 56, the inertial mass generated when the steering unit 50 changes the traveling direction of the electric vehicle 10 can be reduced. Thereby, the steerability of the electric vehicle 10 is improved.

[0030] The air conditioning unit 60 includes an air conditioner 62, a heat medium pipe 64, a heat exchanger 66, and a fan 68. The air conditioner 62 is disposed in the front compartment F1 of the electric vehicle 10. The air conditioner 62 is an air compressor. The heat medium pipe 64 extends in the vehicle longitudinal direction and connects the air conditioner 62 and the heat exchanger 66. The heat medium pipe 64 constitutes a path for circulating a heat medium (e.g., antifreeze or water) compressed or expanded by the air conditioner 62 between the air conditioner 62 and the heat exchanger 66. That is, although the heat medium pipe 64 is connected to the drive device 20 via at least the heat exchanger 66 and the instrument panel 3, it is not directly connected to the drive device 20. The fan 68 supplies conditioned air to the passenger compartment via the heat exchanger 66 and the instrument panel 3. In this way, the air conditioner 62 conditions the passenger compartment of the electric vehicle 10.

[0031] Referring to FIGS. 2 and 3, the detailed structure of the drive device 20 will be described. FIG. 2 shows a cross-sectional view of the drive device 20 taken along line II-II of FIG. 1. That is, FIG. 2 shows the structure of the drive device 20 when viewed from the rear. FIG. 3 shows a cross-sectional view of the drive device 20 taken along line III-III of FIG. 2. That is, FIG. 3 shows the structure of the drive device 20 when viewed from the left.

[0032] The motor unit 30 includes an electric motor 31 and a first casing 34. The electric motor 31 includes a rotor 32R having a cylindrical shape extending in the left-right direction, a stator 32S facing the outer peripheral surface of the rotor 32R from the radially outer side, and a motor shaft 35 extending in the left-right direction through the rotor 32R. The rotor 32R includes permanent magnets. The electric motor 31 is a radial-type motor. In a modified example, the electric motor 31 may be an axial-type motor.

[0033] The first casing 34 includes a housing 34H, a first cover 36R, and a second cover 36L. The housing 34H faces the outer peripheral surface of the stator 32S of the electric motor 31 from the radially outer side. The first end face 34R located at the right end of the housing 34H and the second end face 34L located at the left end define an opening. The housing 34H extends cylindrically in the left - right direction from the first end face 34R to the second end face 34L.

[0034] The first cover 36R is attached to the first end face 34R of the housing 34H from the right. The first cover 36R has a flat plate shape extending in a direction orthogonal to the motor shaft 35 of the electric motor 31, and covers the opening of the first end face 34R of the housing 34H from the right. The first cover 36R includes a first bearing 33R. The first bearing 33R rotatably holds the motor shaft 35.

[0035] Similarly, the second cover 36L is attached to the second end face 34L of the housing 34H from the left. The second cover 36L has a flat plate shape extending in a direction orthogonal to the motor shaft 35 of the electric motor 31, and covers the opening of the second end face 34L of the housing 34H from the right. The second cover 36L includes a second bearing 33L. The second bearing 33L rotatably holds the motor shaft 35.

[0036] The first cover 36R includes a first stay 38R that extends upward from the upper end of the first cover 36R toward the inverter unit 70. Similarly, the second cover 36L includes a second stay 38L that extends upward from the upper end of the second cover 36L toward the inverter unit 70.

[0037] The inverter unit 70 includes an inverter 72 and a second casing 74. The inverter 72 is a power conversion device that converts the DC power of the battery pack 42 into AC power suitable for the electric motor 31. Further, the inverter 72 may include, for example, a converter function for boosting the DC power of the battery pack 42. The second casing 74 houses the inverter 72.

[0038] The first stay 38R and the second stay 38L of the motor unit 30 extend toward the second casing 74 of the inverter unit 70. The right end of the second casing 74 of the inverter unit 70 is fixed to the first stay 38R of the motor unit 30 via a bolt B1. Similarly, the left end of the second casing 74 is fixed to the second stay 38L via a bolt B1. Thereby, the second casing 74 of the inverter unit 70 is held above the first casing 34 of the motor unit 30.

[0039] Also, the first cover 36R of the motor unit 30 is fixed to the vehicle body 2 via the first bracket 6R and a bolt B2. Similarly, the second cover 36L is fixed to the vehicle body 2 via the second bracket 6L and a bolt B2. In this way, the drive device 20 is mounted on the vehicle body 2.

[0040] A transmission mechanism unit 80 is attached to the first cover 36R. The transmission mechanism unit 80 includes a plurality of gears 82, 86 (see FIG. 3) and a third casing 84 that houses them. The motor shaft 35 of the electric motor 31 passes through the first cover 36R and extends further to the right, and is rotatably held by the third bearing 83 of the third casing 84. The motor shaft 35 rotates the gear 82 within the third casing 84. The third casing 84 includes a side portion that extends in the front-rear direction to the right of the motor unit 30 and a front portion that is located in front of the motor unit 30. As shown in FIG. 3, a gear 86 is housed in the front portion of the third casing 84. The gear 86 is fixed to the front shaft 14. The gear 82 and the gear 86 are engaged via a plurality of gears (not shown). Therefore, when the gear 82 is rotated by the motor shaft 35, the gear 86 rotates, and a pair of front wheels 4R, 4L are driven via the front shaft 14 (see FIG. 1).

[0041] As described above, the second casing 74 of the inverter unit 70 is held above the first casing 34 of the motor unit 30 by the first stay 38R of the first cover 36R and the second stay 38L of the second cover 36L of the motor unit 30. Each stay 38R, 38L extends upward from each cover 36R, 36L. For this reason, the lower surface of the second casing 74 is separated from the upper surface of the housing 34H over the entire range of the housing 34H of the first casing 34. As a result, a wide accommodation space SP1 having the same width as the length from the first end face 34R to the second end face 34L of the housing 34H is provided between the second casing 74 and the cylindrically extending housing 34H. Thereby, it becomes possible to arrange a part or all of various components such as the power cable 44, the steering shaft 54, and the heat medium pipe 64 in the accommodation space SP1. Further, by attaching the second casing 74 to each of the covers 36R, 36L of the first casing 34, the accommodation space SP1 can be provided between the second casing 74 and the first casing 34 with a simple configuration as compared with a configuration in which the second casing 74 is fixed by a bracket different from each of the covers 36R, 36L.

[0042] As shown in FIG. 3, the accommodation space SP1 penetrates the drive device 20 in the vehicle longitudinal direction. The power cable 44 passes through the accommodation space SP1 to electrically connect the charging inlet 46 and the battery pack 42. The steering shaft 54 passes through the accommodation space SP1 to mechanically connect the steering wheel 52 and the gear of the steering gearbox 56. The heat medium pipe 64 passes through the accommodation space SP1 to fluidly connect the air conditioner 62 and the heat exchanger 66. That is, a part of the power cable 44 is located within the accommodation space SP1. Similarly, a part of the steering shaft 54 and a part of the heat medium pipe 64 are located within the accommodation space SP1.

[0043] (Effect of this embodiment) In the electric vehicle 10 of the present embodiment, a power cable 44, a steering shaft 54, and a part of a heat medium pipe 64 that are not directly connected to the drive device 20 are located in an accommodation space SP1 positioned between the first casing 34 and the second casing 74. Therefore, the degree of freedom in the layout of the power cable 44, the steering shaft 54, and the heat medium pipe 64 can be improved. As a result, the degree of freedom in the layout of the drive device 20 mounted on the electric vehicle 10, a charging inlet 46 to which the power cable 44 is connected, a steering gear box 56 to which the steering shaft 54 is connected, and an air conditioner 62 to which the heat medium pipe 64 is connected can be improved. As a result, the accommodation space in the front compartment F1 can be utilized more effectively.

[0044] Furthermore, as shown in FIG. 3, the front portion of the third casing 84 of the transmission mechanism unit 80 is adjacent to the front of the first casing 34 of the motor unit 30. The accommodation space SP1 is also provided between the front portion of the third casing 84 and the second casing 74. The front portion of the accommodation space SP1 is located between the second casing 74 and the third casing 84. In other words, the accommodation space SP1 also passes between the front portion of the third casing 84 and the second casing 74 and penetrates the drive device 20 in the vehicle longitudinal direction. A large accommodation space SP1 extending in the vehicle longitudinal direction can be provided not only between the first casing 34 and the second casing 74 but also between the second casing 74 and the third casing 84. Thereby, a part of a component such as a steering shaft 54 extending in the vehicle longitudinal direction can be arranged in the accommodation space SP1.

[0045] Furthermore, the front portion of the third casing 84 is disposed below the first casing 34. That is, the front portion of the third casing 84 and the first casing 34 are arranged along the direction D1 in which they are displaced downward as they go forward in the vehicle. In other words, when viewed from the left, the straight line connecting the center of the housing 34H of the first casing 34 and the center of the third casing 84 is inclined so as to approach the vehicle body 2 more in the front. Since the first casing 34 and the third casing 84 are arranged along the direction D1, the accommodation space SP1 extends in the vehicle front-rear direction along the direction D1. Therefore, a part of the steering shaft 54 that is inclined upward as it goes rearward in the vehicle toward the steering wheel 52 can be easily accommodated.

[0046] In this embodiment, the inverter 72 is an example of a "power conversion device". The power cable 44, the steering shaft 54, and the heat medium pipe 64 are examples of "in-vehicle components".

[0047] As described above, specific examples of the technology disclosed in this specification have been described in detail, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples exemplified above. Modifications of the above embodiments are listed below.

[0048] (Modification 1) In the above-described embodiment, the second casing 74 of the inverter unit 70 is fixed to the covers 36R and 36L of the motor unit 30. In this modification, the second casing 74 may be fixed to a bracket provided on the upper surface of the first casing 34 of the motor unit 30, for example.

[0049] (Modification 2) The covers 36R and 36L of the first casing 34 may not be provided with stays. In that case, the second casing 74 of the inverter unit 70 may be provided with a pair of stays extending downward toward the first casing 34, and the pair of stays may be fixed to the covers 36R and 36L, respectively.

[0050] (Modification Example 3) The inverter unit 70 may be located below the motor unit 30.

[0051] (Modification Example 4) The drive device 20 may not include the transmission mechanism unit 80. In that case, the transmission mechanism unit 80 may be arranged separately from the drive device 20. In another modification example, the third casing 84 of the transmission mechanism unit 80 may be adjacent to the first casing 34 of the motor unit 30 from the rear, or may be adjacent from the left - right direction.

[0052] (Modification Example 5) The front portions of the first casing 34 of the motor unit 30 and the third casing 84 of the transmission mechanism unit 80 do not have to be arranged along the direction D1. Each of the casings 34, 84 may be arranged, for example, along the vehicle longitudinal direction.

[0053] (Modification Example 6) At least one of the power cable 44, the steering shaft 54, and the heat medium pipe 64 does not have to pass through the accommodation space SP1. In another modification example, for example, a refrigerant pipe that extends in the vehicle longitudinal direction from a radiator located at the front of the electric vehicle 10 and supplies refrigerant to the battery pack 42 may pass through the accommodation space SP1. In this case, the refrigerant pipe is an example of an "in - vehicle component".

[0054] The technical elements described in this specification or the drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Also, the technologies illustrated in this specification or the drawings can achieve a plurality of purposes simultaneously, and achieving one of those purposes itself has technical utility.
