The center console 63 can be provided with, for example, an armrest in addition to these.

ここで、図６に示すエアコンディショナ５７から送り出され、吸気ダクト５５の図２に示す導入口６６を介してケース本体３１の第１収納部４５内の上部に導入された空調風は、第１収納部４５内を上から下に移動し、連結部４７内を車幅方向に通過し、さらに第２収納部４６内を車幅方向に通過して排気ダクト６１の排気口６８から車室内に排出されることになる。このとき、排気ダクト６１のファンユニット６０によってケース本体３１内からの空調風の吸い出しも行う。このようにケース本体３１の連結部４７は第１収納部４５と第２収納部４６とを連通させる連結ダクトを兼用している。   Here, the conditioned air sent out from the air conditioner 57 shown in FIG. 6 and introduced into the upper portion of the first housing 45 of the case body 31 through the inlet 66 shown in FIG. The first storage unit 45 moves from top to bottom, passes through the connecting unit 47 in the vehicle width direction, passes through the second storage unit 46 in the vehicle width direction, and passes through the exhaust port 68 of the exhaust duct 61 from the vehicle interior. Will be discharged. At this time, the fan unit 60 of the exhaust duct 61 also sucks out the conditioned air from the case body 31. As described above, the connecting portion 47 of the case body 31 also serves as a connecting duct that allows the first storage portion 45 and the second storage portion 46 to communicate with each other.

そして、空調風は、第１収納部４５を通過する際に、高圧バッテリ３２内のバッテリ本体６７の温度調節と、インバータ３３の温度調節とを行い、第２収納部４６を通過する際にＰＣＵ３４の温度調節を行う。   The conditioned air adjusts the temperature of the battery body 67 in the high voltage battery 32 and the temperature of the inverter 33 when passing through the first storage unit 45, and the PCU 34 when passing through the second storage unit 46. Adjust the temperature.

図６に示すように、インストルメントパネル５６内に配置されたエアコンディショナ５７のエアコンダクト５８は、エアコンディショナ５７において常にほぼ一定温度であるエバポレータ６９とヒータ７０との間から分岐して上記した吸気ダクト５５に連通されており、この分岐位置には、開閉可能な第１開閉部７１が設けられている。つまり、第１開閉部７１は、エアコンディショナ５７のファン７２により送り出されエバポレータ６９を通過した空調風を、一部吸気ダクト５５に流す開状態と、吸気ダクト５５に一切流さない閉状態とに切り替えられる。なお、吸気ダクト５５に流れなかった空調風はエアコンダクト５８を介して車室内に吹き出される。吸気ダクト５５内には第１温度センサ７３が設けられている。   As shown in FIG. 6, the air conditioner duct 58 of the air conditioner 57 disposed in the instrument panel 56 branches from between the evaporator 69 and the heater 70, which is always at a substantially constant temperature, in the air conditioner 57. A first opening / closing part 71 that can be opened and closed is provided at this branching position. That is, the first opening / closing section 71 is in an open state in which the conditioned air sent by the fan 72 of the air conditioner 57 and passed through the evaporator 69 is partially passed through the intake duct 55 and in a closed state in which no air flows through the intake duct 55. Can be switched. The conditioned air that has not flowed into the intake duct 55 is blown out into the vehicle compartment via the air conditioner duct 58. A first temperature sensor 73 is provided in the intake duct 55.

ここで、一般的に車室内において暖房時に温度が低い位置は、フロアパネル１１近傍の運転席２２および助手席２３の間の位置であり、図２に示すように、この位置に配置されたケース本体３１の上板部４０と右側の側板部４２との境界部分には、開閉可能な第２開閉部７５が形成されている。第２開閉部７５は、ケース本体３１の内外を連通させることで高圧電装ケース３０内に冷却風を取り込む冷却風吸気口７５Ａと、冷却風吸気口７５Ａを開閉させる開閉部材７５Ｂとを有しており、開閉部材７５Ｂで冷却風吸気口７５Ａを開放させることにより車室内とケース本体３１内とで空気を流通させる開状態と、開閉部材７５Ｂで冷却風吸気口７５Ａを閉塞させることにより車室内とケース本体３１内とで空気を流通させない閉状態とに切り替えられ、第２開閉部７５が開状態とされて排気ダクト６１のファンユニット６０が空気をケース本体３１内から吸い出すと、第２開閉部７５からケース本体３１の第１収納部４５内に空気が導入されて、この空気が第１収納部４５、連結部４７および第２収納部４６をこの順番で通過して排気ダクト６１から車室内に排出されることになる。そして、空気は、第１収納部４５を通過する際に高圧バッテリ３２およびインバータ３３の温度調節を行い、第２収納部４６を通過する際にＰＣＵ３４の温度調節を行う。この第２開閉部７５の近傍の外側には第２温度センサ７６が設けられている。   Here, in general, a position where the temperature is low during heating in the passenger compartment is a position between the driver seat 22 and the passenger seat 23 in the vicinity of the floor panel 11, and as shown in FIG. 2, the case is arranged at this position. A second opening / closing portion 75 that can be opened and closed is formed at a boundary portion between the upper plate portion 40 of the main body 31 and the right side plate portion 42. The second opening / closing part 75 includes a cooling air intake port 75A that takes in cooling air into the high piezoelectric device case 30 by communicating the inside and outside of the case body 31, and an opening / closing member 75B that opens and closes the cooling air intake port 75A. In addition, the cooling air intake port 75A is opened by the opening / closing member 75B to open the air flow between the vehicle interior and the case body 31, and the cooling air intake port 75A is closed by the opening / closing member 75B. When the second opening / closing part 75 is opened and the fan unit 60 of the exhaust duct 61 sucks air out of the case main body 31, the second opening / closing part is switched to the closed state in which air does not flow in the case main body 31. 75, air is introduced into the first storage part 45 of the case body 31, and the air passes through the first storage part 45, the connecting part 47, and the second storage part 46 in this order, and is exhausted. And it is discharged into the vehicle interior from the transfected 61. The air adjusts the temperature of the high voltage battery 32 and the inverter 33 when passing through the first storage unit 45, and adjusts the temperature of the PCU 34 when passing through the second storage unit 46. A second temperature sensor 76 is provided outside the vicinity of the second opening / closing part 75.

ここで、ケース本体３１における運転席２２と助手席２３との間位置であって、センタコンソール６３と運転席２２との間位置であり、しかも内部に配設された高圧バッテリ３２よりも上側位置に、第２開閉部７５の冷却風吸気口７５Ａが設けられている。この冷却風吸気口７５Ａは運転席２２の方向、具体的にはシートクッション２０の方向に指向している。なお、第２開閉部７５を助手席２３側に設けても良い。この場合、ケース本体３１における運転席２２と助手席２３との間位置であって、センタコンソール６３と助手席２３との間位置であり、しかも内部に配設された高圧バッテリ３２よりも上側位置に、高圧電装ケース３０内に冷却風を取り込む第２開閉部７５の冷却風吸気口７５Ａが設けられることになり、この冷却風吸気口７５Ａが助手席２３の方向、具体的にはシートクッション２０の方向に指向する。   Here, in the case main body 31, it is a position between the driver's seat 22 and the passenger seat 23, a position between the center console 63 and the driver's seat 22, and a position above the high-voltage battery 32 disposed inside. In addition, a cooling air inlet 75A of the second opening / closing part 75 is provided. 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

そして、図示せぬバッテリ温度センサで検出される高圧バッテリ３２の温度と、第１温度センサ７３および第２温度センサ７６の検出結果とに基づいて、第１開閉部７１および第２開閉部７５の開閉を制御する。つまり、運転席２２および助手席２３の間の位置の温度と、エアコンディショナ５７の空調風の温度とを比較して、そのときの高圧バッテリ３２に適した温度の空気を高圧電装ケース３０のケース本体３１内に取り入れるのである。その制御は、例えば以下のように行われる。   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.

高圧バッテリ３２の温度を検出しバッテリ温度Ｔが所定値例えば２０℃の場合は、排気ダクト６１のファン６０は停止させる。つまり、現状の温度が高圧バッテリ３２に適した温度である場合は温度調節を行わないのである。   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.

バッテリ温度Ｔが所定値例えば２０℃より大きい場合は、排気ダクト６１のファン６０を駆動するとともに、第１温度センサ７３で検出されるエアコン廻り温度Ｔ１と、第２温度センサ７６で検出される運転席助手席間温度Ｔ２とを比較し、Ｔ１＝Ｔ２の場合は、第２温度センサ７６側の第２開閉部７５を閉じ、第１温度センサ７３側の第１開閉部７１を開く。Ｔ１＞Ｔ２の場合は、第２温度センサ７６側の第２開閉部７５を開き、第１温度センサ７３側の第１開閉部７１を閉じる。Ｔ１＜Ｔ２の場合は、第１温度センサ７３側の第１開閉部７１を開き、第２温度センサ７６側の第２開閉部７５を閉じる。つまり、高圧バッテリ３２の温度が高く冷却が必要な状態であるとき、エアコンディショナ５７と運転席助手席間とのうち温度が低い方の空気を高圧電装ケース３０内に流す。   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.

バッテリ温度Ｔが所定値例えば２０℃より小さい場合は、排気ダクト６１のファン６０を駆動するとともに、エアコン廻り温度Ｔ１と運転席助手席間温度Ｔ２とを比較し、Ｔ１＝Ｔ２の場合は、第２温度センサ７６側の第２開閉部７５を閉じ、第１温度センサ７３側の第１開閉部７１を開く。Ｔ１＞Ｔ２の場合は、第１温度センサ７３側の第１開閉部７１を開き、第２温度センサ７６側の第２開閉部７５を閉じる。Ｔ１＜Ｔ２の場合は、第２温度センサ７６側の第２開閉部７５を開き、第１温度センサ７３側の第１開閉部７１を閉じる。つまり、高圧バッテリ３２の温度が低く加温が必要な状態であるとき、エアコンディショナ５７と運転席助手席間とのうち温度が高い方の空気を高圧電装ケース３０内に流す。   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.

以上に述べたように、本実施形態によれば、車幅方向に並置された一列目の運転席２２と助手席２３との間に高圧電装ケース３０を配設し、この高圧電装ケース３０内に高圧バッテリ３２を収納しているため、二列目あるいは三列目等の後部座席の座席下に高圧バッテリ３２を配設する必要が無くなる。したがって、重量配分を良好にできる上、二列目あるいは三列目等の後部座席に対し良好なシートアレンジが可能となり室内を有効に利用できるため優れた商品性が得られる。さらに、車両前部に搭載されるエアコンディショナ５７の近くに高圧電装ケース３０を配設できるため、吸気ダクト５５を短くできる等、高圧電装ケース３０への温度調節風の導入が容易となる。   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.

また、高圧電装ケース３０が助手席２３のシート下まで延設されているため、運転席２２と助手席２３との間に配置される部分の高さを抑えることができる。したがって、上記のように高圧電装ケース３０の運転席２２と助手席２３との間に配置される部分にセンタコンソール６３を配置する等、車室内スペースを有効に利用することができる。   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.

さらに、高圧電装ケース３０が助手席２３のシート下まで延設されているため、高圧電装ケース３０内で高圧バッテリ３２およびＰＣＵ３４を並設させてこれらを高圧ケーブル５０でつないだ場合に高圧ケーブル５０をも高圧電装ケース３０内に収納し保護することができる。   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.

加えて、高圧電装ケース３０を助手席２３のシート下まで延設させ、高圧電装ケース３０内で高圧バッテリ３２とＰＣＵ３４とを並設させるため、高圧電装ケース３０を高圧バッテリ３２およびＰＣＵ３４の温度調節用のダクトとして兼用でき、軽量化およびコストダウンを図れる。なお、高圧電装ケース３０を助手席２３のシート下ではなく運転席２２のシート下まで延設させるようにしても良く、さらには運転席２２および助手席２３の両方のシート下まで延設させるようにしても良い。   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.

さらに、高圧電装ケース３０の上部の凹部４８を前後に跨ぐようにシートレール２５が配設されているため、シートレール２５下の空間を、高圧電装ケース３０内の運転席２２および助手席２３間に配置された高圧電装部品と助手席２３のシート下に配置された高圧電装部品とを結ぶ高圧ケーブル５０の配線スペース等として有効利用できる。さらに、高強度のシートレール２５で衝突時の高圧ケーブル５０の保護ができる。加えて、シートレール２５が邪魔することで高圧電装ケース３０の不用意な取り外しを規制できる。 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 .

高圧電装ケース３０内の運転席２２と助手席２３との間位置に背の高い高圧バッテリ３２を配置することで、シートレール２５の共用化を図ることができる。また、運転席２２と助手席２３との間位置に背の高い高圧バッテリ３２を配置することで、運転席２２および助手席２３のシート下の有効活用が可能となり、例えば運転席２２のシート下にカーナビゲーションシステムやＣＤチェンジャー、オーディオ等を配置できる。   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.

加えて、高圧電装ケース３０内の運転席２２と助手席２３との間位置に高圧バッテリ３２およびインバータ３３が配設されているため、上記のように高圧バッテリ３２の直流電力をインバータ３３で交流電力に変換して利用する場合に、これらを集約配置できて配線を短くでき、その上、交流電力の外部電源端子６２を運転席２２と助手席２３との間位置であって高圧バッテリ３２の後側に配置できるためその使い勝手が向上する。さらに、高圧バッテリ３２とインバータ３３とを一体に冷却することができるため、冷却構造を簡素化できる。   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.

また、高圧電装ケース３０の高強度部材であるケース本体３１の上部における運転席２２と助手席２３との間位置にセンタコンソール６３が設けられるため、高圧電装ケース３０をセンターコンソール６３の高さを嵩上げするための部材として利用できる。つまり、ミニバン等のセンタトンネルがない車体フロアを採用した場合、センタコンソールの高さを嵩上げするために別途の高強度部材からなる構造体を車体フロア上に設ける必要があるが、この構造体を、高圧バッテリ３２や高圧電装部品の保護のために高強度の隔壁とされノイズシールド隔壁とされた高強度部材からなる剛性の高いケース本体３１で代用でき、余分な構造体を必要としない。   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.

加えて、第２開閉部７５の冷却風吸気口７５Ａが、高圧電装ケース３０におけるセンタコンソール６３と運転席２２との間位置、つまり一般的に車室内において暖房時に最も温度が低い位置である運転席２２と助手席２３との間位置に設けられているため、効率良く高圧電装ケース３０内を冷却することができる。しかも、一般的に暖房時に運転席２２と助手席２３との間位置では上の方が温度が低くなるため、冷却風吸気口７５Ａが高圧バッテリ３２よりも上側位置に位置することで、さらに効率良く高圧電装ケース３０内を冷却することができる。なお、この場合、上側から吸気し下側から排気すれば自然吸気での冷却も可能となって吸気ダクトを不要とする構成にもできる。さらに、冷却風吸気口７５Ａが運転席２２のシートクッション２０の方向つまり側方に指向しているため、前後に生じやすい熱溜まりの影響を受けにくく、よって、さらに効率良く高圧電装ケース３０内を冷却することができる。さらに、冷却風吸気口７５Ａが運転席２２のシートクッション２０の方向に指向しているため、吸気音をシートクッション２０で消音でき吸音材を削減できる。なお、冷却風吸気口７５Ａを上記とは左右反対に助手席２３に指向して設けても同様の効果が得られる。   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.

さらに、車体フロア１６が四輪駆動車用であってプロペラシャフト５２を配設可能な配設部１１Ａを有している場合に、これをプロペラシャフト５２が不要な前輪駆動車用に使用することで、配設部１１Ａにプロペラシャフト５２に替えて、高圧電装ケース３０内から導かれる高圧ケーブル５１を配索することができる。よって、四輪駆動車と前輪駆動車とが設定される車種において高圧電装ケース３０を配設する場合に、上記のように四輪駆動車用の車体フロア１６を用いることで車体改修を最小限に抑えることができる。   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.

また、四輪駆動車用の車体フロア１６を前輪駆動車に用いて、四輪駆動車におけるプロペラシャフト５２の配置位置に高圧ケーブル５１を配索しているため、上記のように車体改修を最小限に抑えることができる効果に加えて、図示せぬ走行用電動モータと高圧電装部品とを結ぶ高圧ケーブル５１をまっすぐ配索できることから、長さを短縮でき軽量化およびコストダウンを図れる。   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.

さらに、高圧電装ケース３０内から車体フロア１６下に導かれる高圧ケーブル５１が、前後に配設された車体骨格部である高強度のクロスメンバ１４，１５間であって高強度部材であるシートレール２５の真下の導出部１１Ｂで車体フロア１６を貫通しているため、車両衝突時にシートレール２５およびクロスメンバ１４、１５で貫通位置である導出部１１Ｂを保護することができ、その結果、高圧ケーブル５１を保護することができる。   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.

高圧電装部品である高圧バッテリ３２をクロスメンバ１５に固定するとともに、高圧電装部品であるＰＣＵ３４を台部材３６を介してクロスメンバ１５に固定することにより、新規のフレームを必要とせず、コスト増および重量増を回避できる。また、車体改修を極力抑えることができる。   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.

高圧電装部品である高圧バッテリ３２およびＰＣＵ３４を左右のサイドフレーム１３間に配置することで、高圧バッテリ３２およびＰＣＵ３４をサイドフレーム１３で保護することができる。   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.

車室内において最も温度が低い運転席２２および助手席２３の間位置の温度と、エアコンディショナ５７の空調風の温度とを比較して、そのときの高圧バッテリ３２に適した温度の空気を高圧電装ケース３０のケース本体３１内に取り入れるため、高圧バッテリ３２を効率良く利用でき、燃費を低減することができる。   The temperature between the driver's seat 22 and the passenger's seat 23 having the lowest temperature in the passenger compartment is compared with the temperature of the conditioned air of the air conditioner 57, and the air at a temperature suitable for the high voltage battery 32 at that time is high pressure. Since it is taken into the case main body 31 of the electrical case 30, the high voltage battery 32 can be used efficiently and fuel consumption can be reduced.

なお、高圧電装ケース３０内に設けられる高圧電装部品としては、上記した商用電源、走行用電動モータの作動等を制御するＰＣＵ３４の他に、低圧変換器（ＤＣ−ＤＣコンバータ）や、エアコンのコンプレッサ駆動用のインバータ、電動パワーステアリング装置用の制御装置、パワーユニットの制振を行うアクティブマウント装置用の制御装置等がある。   In addition to the above-mentioned commercial power supply, PCU 34 for controlling the operation of the electric motor for traveling, etc., the high-piezoelectric parts provided in the high-piezoelectric equipment case 30 include a low-voltage converter (DC-DC converter), and a compressor for an air conditioner. There are a drive inverter, a control device for an electric power steering device, a control device for an active mount device that controls vibration of a power unit, and the like.
