The cooling air intake port 75A is directed in the direction of the driver's seat 22, specifically, in the direction of the seat cushion 20. The second opening / closing part 75 may be provided on the passenger seat 23 side. In this case, it is a position between the driver's seat 22 and the passenger seat 23 in the case main body 31, a position between the center console 63 and the passenger seat 23, and an upper position than the high-voltage battery 32 disposed inside. In addition, the cooling air intake port 75A of the second opening / closing part 75 that takes in the cooling air into the high piezoelectric equipment case 30 is provided, and this cooling air intake port 75A is in the direction of the passenger seat 23, specifically, the seat cushion 20. Oriented in the direction of

  Based on the temperature of the high voltage battery 32 detected by a battery temperature sensor (not shown) and the detection results of the first temperature sensor 73 and the second temperature sensor 76, the first opening / closing portion 71 and the second opening / closing portion 75 Controls opening and closing. That is, the temperature of the position between the driver's seat 22 and the passenger seat 23 is compared with the temperature of the conditioned air of the air conditioner 57, and air at a temperature suitable for the high voltage battery 32 at that time is supplied to the high piezoelectric equipment case 30. This is taken into the case body 31. The control is performed as follows, for example.

  When the temperature of the high voltage battery 32 is detected and the battery temperature T is a predetermined value, for example, 20 ° C., the fan 60 of the exhaust duct 61 is stopped. That is, when the current temperature is a temperature suitable for the high voltage battery 32, the temperature is not adjusted.

  When the battery temperature T is higher than a predetermined value, for example, 20 ° C., the fan 60 of the exhaust duct 61 is driven, and the temperature around the air conditioner T1 detected by the first temperature sensor 73 and the operation detected by the second temperature sensor 76 are driven. The temperature between the front passenger seat T2 is compared, and when T1 = T2, the second opening / closing part 75 on the second temperature sensor 76 side is closed, and the first opening / closing part 71 on the first temperature sensor 73 side is opened. When T1> T2, the second opening / closing part 75 on the second temperature sensor 76 side is opened, and the first opening / closing part 71 on the first temperature sensor 73 side is closed. When T1 <T2, the first opening / closing part 71 on the first temperature sensor 73 side is opened, and the second opening / closing part 75 on the second temperature sensor 76 side is closed. That is, when the temperature of the high voltage battery 32 is high and cooling is necessary, the air having the lower temperature between the air conditioner 57 and the driver's seat and the passenger's seat is caused to flow into the high piezoelectric equipment case 30.

  When the battery temperature T is smaller than a predetermined value, for example, 20 ° C., the fan 60 of the exhaust duct 61 is driven and the air-conditioner surrounding temperature T1 is compared with the driver seat passenger seat temperature T2, and when T1 = T2, The second opening / closing part 75 on the second temperature sensor 76 side is closed, and the first opening / closing part 71 on the first temperature sensor 73 side is opened. In the case of T1> T2, the first opening / closing part 71 on the first temperature sensor 73 side is opened, and the second opening / closing part 75 on the second temperature sensor 76 side is closed. When T1 <T2, the second opening / closing part 75 on the second temperature sensor 76 side is opened, and the first opening / closing part 71 on the first temperature sensor 73 side is closed. That is, when the temperature of the high voltage battery 32 is low and heating is required, the air having the higher temperature between the air conditioner 57 and the driver's seat and the passenger's seat is caused to flow into the high piezoelectric equipment case 30.

  As described above, according to the present embodiment, the high piezoelectric equipment case 30 is disposed between the driver seat 22 and the passenger seat 23 in the first row juxtaposed in the vehicle width direction. Since the high voltage battery 32 is housed in the second row, it is not necessary to dispose the high voltage battery 32 under the seat of the rear seat such as the second row or the third row. Therefore, the weight distribution can be improved, and a good seat arrangement can be made for the rear seats such as the second row or the third row, and the interior can be used effectively, so that excellent merchantability can be obtained. Furthermore, since the high-voltage equipment case 30 can be disposed near the air conditioner 57 mounted on the front portion of the vehicle, the intake duct 55 can be shortened and the temperature-controlled air can be easily introduced into the high-voltage equipment case 30.

  In addition, since the high piezoelectric equipment case 30 extends to a position below the passenger seat 23, the height of the portion disposed between the driver seat 22 and the passenger seat 23 can be suppressed. Therefore, the vehicle interior space can be used effectively, for example, by disposing the center console 63 in the portion disposed between the driver seat 22 and the passenger seat 23 of the high piezoelectric equipment case 30 as described above.

  Further, since the high voltage equipment case 30 extends under the passenger seat 23, when the high voltage battery 32 and the PCU 34 are arranged in parallel in the high voltage equipment case 30 and are connected by the high voltage cable 50, the high voltage cable 50. Can be housed and protected in the high-voltage packaging case 30.

  In addition, in order to extend the high piezoelectric equipment case 30 under the seat of the passenger seat 23 and to arrange the high voltage battery 32 and the PCU 34 in the high piezoelectric equipment case 30, the high voltage equipment case 30 is adjusted in temperature of the high voltage battery 32 and the PCU 34. It can also be used as a duct for use, reducing weight and reducing costs. Note that the high piezoelectric equipment case 30 may be extended not under the passenger seat 23 but under the driver seat 22, and further under both the driver seat 22 and the passenger seat 23. Anyway.

Furthermore, since the seat rail 25 is disposed so as to straddle the concave portion 48 on the upper portion of the high-voltage equipment case 30 in the front-rear direction, a space below the seat rail 25 is provided between the driver seat 22 and the passenger seat 23 in the high-voltage equipment case 30. Can be effectively used as a wiring space of the high-voltage cable 50 that connects the high-piezoelectric component arranged at the high-voltage cable 50 and the high-piezoelectric component arranged under the passenger seat 23. Further, the high-strength seat rail 25 can protect the high-voltage cable 50 at the time of collision. In addition, inadvertent removal of the high voltage electrical equipment case 30 can be regulated by the seat rail 25 interfering .

  By arranging the tall high-voltage battery 32 between the driver seat 22 and the passenger seat 23 in the high piezoelectric equipment case 30, the seat rail 25 can be shared. Further, by arranging the tall high voltage battery 32 between the driver seat 22 and the passenger seat 23, the driver seat 22 and the passenger seat 23 can be effectively used under the seat. Car navigation system, CD changer, audio, etc.

  In addition, since the high voltage battery 32 and the inverter 33 are disposed between the driver seat 22 and the passenger seat 23 in the high piezoelectric equipment case 30, the DC power of the high voltage battery 32 is AC converted by the inverter 33 as described above. In the case of conversion to electric power, the wiring can be shortened by concentrating them, and the external power supply terminal 62 for AC power is located between the driver seat 22 and the passenger seat 23 and is connected to the high-voltage battery 32. Usability is improved because it can be placed on the rear side. Furthermore, since the high voltage battery 32 and the inverter 33 can be integrally cooled, the cooling structure can be simplified.

  Further, since the center console 63 is provided between the driver seat 22 and the passenger seat 23 in the upper part of the case main body 31 which is a high strength member of the high piezoelectric equipment case 30, the high piezoelectric equipment case 30 is provided with a height of the center console 63. It can be used as a member for raising the volume. In other words, when a vehicle floor that does not have a center tunnel such as a minivan is adopted, it is necessary to provide a structure made of a separate high-strength member on the vehicle body floor in order to increase the height of the center console. In order to protect the high-voltage battery 32 and the high-voltage electrical component, the case body 31 having a high rigidity made of a high-strength member which is a high-strength partition wall and a noise shield partition wall can be substituted, and no extra structure is required.

  In addition, the cooling air intake port 75A of the second opening / closing part 75 is located at a position between the center console 63 and the driver's seat 22 in the high-piezoelectric equipment case 30, that is, a position where the temperature is generally the lowest during heating in the passenger compartment. Since it is provided between the seat 22 and the passenger seat 23, the inside of the high piezoelectric case 30 can be efficiently cooled. Moreover, since the temperature is generally lower at the position between the driver's seat 22 and the passenger seat 23 during heating, the cooling air inlet 75A is positioned above the high-voltage battery 32, thereby further improving the efficiency. The inside of the high piezoelectric case 30 can be cooled well. In this case, if intake is performed from the upper side and exhaust is performed from the lower side, natural intake air can be cooled, and an intake duct is not required. Further, since the cooling air intake port 75A is oriented in the direction of the seat cushion 20 of the driver's seat 22, that is, to the side, it is not easily affected by heat accumulation that tends to occur in the front and rear, and therefore, the inside of the high piezoelectric equipment case 30 can be more efficiently performed. Can be cooled. Furthermore, since the cooling air intake port 75A is directed toward the seat cushion 20 of the driver's seat 22, the intake sound can be silenced by the seat cushion 20, and the sound absorbing material can be reduced. The same effect can be obtained even if the cooling air intake port 75A is provided facing the passenger seat 23 in the opposite direction to the above.

  Further, when the vehicle body floor 16 is for a four-wheel drive vehicle and has a disposition portion 11A on which the propeller shaft 52 can be disposed, this should be used for a front wheel drive vehicle that does not require the propeller shaft 52. Thus, in place of the propeller shaft 52, the high voltage cable 51 guided from the inside of the high piezoelectric equipment case 30 can be routed in the arrangement portion 11A. Therefore, when the high piezoelectric equipment case 30 is disposed in a vehicle type in which a four-wheel drive vehicle and a front wheel drive vehicle are set, the vehicle body modification is minimized by using the vehicle body floor 16 for the four-wheel drive vehicle as described above. Can be suppressed.

  In addition, since the vehicle body floor 16 for a four-wheel drive vehicle is used as a front wheel drive vehicle and the high-voltage cable 51 is routed at the position of the propeller shaft 52 in the four-wheel drive vehicle, the vehicle body modification is minimized as described above. In addition to the effect that can be suppressed to the limit, the high-voltage cable 51 that connects the electric motor for travel (not shown) and the high-piezoelectric component can be routed straight, so that the length can be shortened and the weight and cost can be reduced.

  Further, the high-voltage cable 51 led from the inside of the high-piezoelectric equipment case 30 to the bottom of the vehicle body floor 16 is between the high-strength cross members 14 and 15 which are the vehicle body skeleton portions arranged at the front and rear, and is a seat rail which is a high-strength member. Since the lead-out portion 11B immediately below the vehicle body 16 passes through the vehicle body floor 16, the seat rail 25 and the cross-members 14 and 15 can protect the lead-out portion 11B at the penetration position in the event of a vehicle collision. 51 can be protected.

  By fixing the high-voltage battery 32, which is a high-piezoelectric component, to the cross member 15, and fixing the PCU 34, which is a high-piezoelectric component, to the cross member 15 via the base member 36, a new frame is not required, and the cost increases. An increase in weight can be avoided. In addition, vehicle body repair can be suppressed as much as possible.

  By arranging the high voltage battery 32 and the PCU 34, which are high piezoelectric components, between the left and right side frames 13, the high voltage battery 32 and the PCU 34 can be protected by the side frame 13.
