The first mounting portion 53 is connected to the support portion 51. Specifically, the first mounting portion 53 is connected to the second end portion of the support portion 51 on the side opposite to the first end portion on the side to which the connecting portion 52 is connected. In the present embodiment, among the second ends of the support portion 51, the directions are orthogonal to both the direction connecting the first end portion and the second end portion and the thickness direction of the support portion 51 (vehicle width direction). A pair of first mounting portions 53 are connected to two separated portions. However, the number of the first mounting portions 53 (the number of mounting points on the battery case 30) is not limited to 2. The number of the first mounting portions 53 may be 1 or 3 or more.

As shown in FIGS. 1, 2, 5, and the like, the first mounting portion 53 is fixed to the upper surface of the battery case 30 by a fixing member 83 such as a bolt.

As shown in FIG. 2, the intake duct 60 is arranged below the blower 40 (between the blower 40 and the body 11).

The exhaust duct 70 is a duct that guides the cooling air generated by the blower 40 into the battery case 30. The upstream end of the exhaust duct 70 is connected to the exhaust port 44 of the blower 40. As shown in FIGS. 4 and 5, the exhaust duct 70 has a mounting piece 78 provided near the downstream end of the exhaust duct 70. The mounting piece 78 is provided with a hole for inserting a mounting member 88 such as a clip. The exhaust duct 70 is fixed to the battery 20 by inserting the mounting member 88 into the hole of the mounting piece 78 in a state where the downstream end of the exhaust duct 70 is connected to the battery case 30.

Next, the procedure for assembling the mounting structure of the battery cooling device will be described.
(1st assembly A)
First, as shown in FIG. 4, when the vertical posture of the blower bracket 50 is turned upside down, the fixing portion 55 provided on the support portion 51 is inserted into the hole of the mounting portion 45 of the blower 40. The blower 40 is placed on the support portion 51. After that, the fixing member 85 is connected to the fixing portion 55, and the connecting portion 46 is connected to the hole 56 of the connecting portion 52. As a result, the blower 40 is assembled to the blower bracket 50.

Subsequently, the intake duct is connected to the exhaust port 44 of the blower 40 at the upstream end of the exhaust duct 70, and is connected to the intake port 43 of the blower 40 at the downstream end of the intake duct 60. The mounting member 87 is inserted into the hole of the mounting piece 67 of 60 and the hole of the mounting portion 47 of the blower 40. As a result, the assembly of the intake duct 60 and the exhaust duct 70 to the blower 40 is completed. As a result, the first assembly A (an assembly including a blower 40, a blower bracket 50, an intake duct 60, and an exhaust duct 70) is formed.

(2nd assembly B)
Next, as shown in FIG. 5, the first mounting portion 53 of the first assembly A is fixed to the front end portion of the upper surface of the battery case 30 by the fixing member 83. Then, in a state where the downstream end of the exhaust duct 70 is connected to the battery case 30, the mounting piece 78 is connected to the battery 20 by the mounting member 88. As a result, the second assembly B (an assembly including a battery 20, a battery case 30, a blower 40, a blower bracket 50, an intake duct 60, and an exhaust duct 70) is formed. FIG. 6 is a plan view of the second assembly B.

(Third assembly C)
Finally, as shown in FIG. 7, the front end portion of the battery case 30 is fixed to the top wall 12a of the body cloth 12 of the body 11 by a fixing member 91 such as an earth bolt and a fixing member 92 such as a bolt. The rear end portion of the battery case 30 is fixed to a portion of the body 11 behind the body cloth 12 by a fixing member (bolt or the like) (not shown). Then, the second mounting portion 54 of the second assembly B is fixed to the top wall 12a of the body cloth 12 by the fixing member 84. As a result, the third assembly C is formed. FIG. 1 is a perspective view of the third assembly C.

As described above, in the mounting structure of the battery cooling device of the present embodiment, since the first mounting portion 53 of the blower bracket 50 supporting the blower 40 is fixed to the battery case 30, the blower bracket 50 is mounted. The battery 20 and the blower 40 can be integrally assembled via the storage chamber 10, that is, the second assembly can be assembled into the storage chamber 10. Therefore, in the mounting structure of the battery cooling device, it is possible to simplify the work of assembling the battery 20 and the blower 40 to the vehicle. For example, when assembling the blower 40 to the vehicle, the work of the worker getting into the vehicle can be omitted.

Further, in the present embodiment, the second mounting portion 54 is fixed to the body cloth 12. Therefore, the fixing strength of the second mounting portion 54 is secured. However, the second mounting portion 54 may be fixed to a portion of the body 11 other than the body cloth 12.

Further, since the support portion 51 is arranged on the upper surface of the blower 40, that is, a portion in the vehicle interior 1 that receives the load of the user or the luggage, the blower 40 is effectively protected. Therefore, a configuration for increasing the strength of the blower 40 becomes unnecessary. Further, a configuration (bracket or the like) for fixing the lower portion of the blower 40 to the body 11 becomes unnecessary.

Further, since the support portion 51 has a shape that covers the blower 40 from above, the blower 40 is prevented from being exposed to water even when it is exposed to water from above the mounting structure of the battery cooling device. .. Therefore, the waterproof structure of the blower 40 can be omitted.

Further, since the intake duct 60 is arranged between the blower 40 and the body 11, in other words, since the blower 40 is provided at a position separated upward from the body 11, it is located on the upstream side of the intake duct 60. It is suppressed that the water that has entered through the intake opening and the water that has accumulated in the body 11 reaches the blower 40.

Further, since the intake port 43 of the blower 40 is opened downward, the sound generated when the blower 40 is driven is effectively attenuated until it reaches the position of the user's ear in the vehicle interior 1.

Next, a modified example of the mounting structure of the battery cooling device of the above embodiment will be described with reference to FIGS. 8 and 9. 8 and 9 are perspective views showing a modified example of the mounting position of the unit including the blower and the blower bracket on the battery case.

As shown in FIG. 8, the first mounting portion 53 may be fixed to the left end of the upper surface of the battery case 30 so that the blower 40 is arranged on the left side of the battery 20. Alternatively, although not shown, the first mounting portion 53 may be fixed to the right end of the upper surface of the battery case 30 so that the blower 40 is arranged on the right side of the battery 20. That is, the first mounting portion 53 may be fixed to the end portion of the upper surface of the battery case 30 in the vehicle width direction so that the blower 40 and the battery 20 are lined up in the vehicle width direction.

Further, as shown in FIG. 9, the first mounting portion 53 may be fixed to the rear end portion of the upper surface of the battery case 30 so that the blower 40 is arranged behind the battery 20. That is, the first mounting portion 53 may be fixed to an end portion of the upper surface of the battery case 30 in the vehicle front-rear direction so that the blower 40 and the battery 20 are lined up in the vehicle front-rear direction.

In these modified examples, the same effect as that of the above embodiment can be obtained.
