【0002】
【従来の技術】
従来、上述例の車両には電気モータを駆動するためのバッテリが搭載されている。このバッテリの搭載位置としては諸種の場所が考えられるが、車室空間、荷室空間を阻害しない場合には、例えば特開平5−238273号公報に記載の如くフロアパネルの下部にバッテリトレイを介して搭載する構成が考えられる。
【0003】
この特開平5−238273号公報のようにフロアパネルの下部にバッテリを搭載した場合には、車室空間、荷室空間を阻害しない利点がある反面、車両の最低地上高が不利となり、加えて車両に対する側突時の剛性を向上させるためには、別途に新たなクロスメンバを追加する必要がある等の問題点があった。
【0004】
【発明が解決しようとする課題】
この発明は、バッテリをフロアバネル上に車幅方向に設け、バッテリの車外側の端部を車両側部の強度部材(サイドシル、センタピラー参照)に固定することで、バッテリにより強度部材を補強することができ、別途クロスメンバを追加することなく側突に対する車体剛性の向上を図ることができ、車両の最低地上高も有利となり、しかも車両中央において車両前後方向に延びるトンネル部の両側に上述のバッテリを配設し、両側に配設されたバッテリ相互間を、トンネル部を跨ぐ補強部材で連結することで、デッドスペースを有効利用してバッテリを配設することができ、車室内の空間の有効利用を図りつつ、バッテリ容量を増加することも可能となる車両のバッテリ搭載構造の提供を目的とする。
【0005】
この発明の一実施態様は、上述のバッテリの車幅方向の両端部を、車両上下方向に配設されたピラーの基部に固定することで、バッテリを側突時のピラー内倒れ防止用の補強部材として有効利用し、ピラーの内倒れを阻止することができる車両のバッテリ搭載構造の提供を目的とする。
【0006】
この発明の一実施態様は、車幅方向に配設されたバッテリを、シートの下方に対応した位置に配設することで、車両側部の強度部材の補強を兼ねるバッテリが、シートの下方つまり乗員着座位置の下方に対応して配設され、側突時における乗員保護性能の向上を図ることができる車両のバッテリ搭載構造の提供を目的とする。
【0007】
【課題を解決するための手段】
この発明による車両のバッテリ搭載構造は、車両にバッテリが配設された車両のバッテリ搭載構造であって、上記バッテリは車両中央において車両前後方向に延びるトンネル部両のフロアパネル上に車幅方向に配設され、上記バッテリの車外側の端部を車両側部の強度部材に固定すると共に、両側に配設されたバッテリ相互間が上記トンネル部を跨ぐ補強部材で連結されたものである。
【0008】
この発明の一実施態様においては、上記バッテリの車幅方向の両端部は車両上下方向に配設されたピラーの基部に固定されてなるものである。
【0009】
この発明の一実施態様においては、車幅方向に配設されたバッテリは、シートの下方に対応した位置に配設されたものである。
【0010】
【発明の作用及び効果】
この発明によれば、上述のバッテリをフロアパネル上に車幅方向に設けて、該バッテリの車外側の端部を車両側部の強度部材に固定したので、バッテリにより車両側部の強度部材を補強することができる。
この結果、別途クロスメンバを追加することなく側突に対する車体剛性の向上を図って、側突時の車両変形を防止することができる効果があり、加えて、車両の最低地上高も有利となる効果がある。
【0011】
しかも、上述のバッテリをトンネル部の両側に配設し、両側に配設されたバッテリ相互間を、トンネル部を跨ぐ補強部材で連結したので、車両両側部の強度部材間がバッテリと補強部材とで車幅方向に連結され、これら両者(バッテリ、補強部材)がクロスメンバと同様の作用を奏する。
さらに、トンネル部の左右両側のデッドスペースを有効利用してバッテリを配設することができ、車室内の空間の有効利用を図りつつ、バッテリ容量を増加することも可能となる効果がある。
【0012】
この発明の一実施態様によれば、上述のバッテリの車幅方向の両端部を、車両上下方向に配設されたピラーの基部に固定したので、バッテリを側突時のピラー内倒れ防止用の補強部材として有効利用し、ピラーの内倒れを阻止することができる効果がある。
【0013】
この発明の一実施態様によれば、車幅方向に配設された上述のバッテリを、シートの下方に対応した位置に配設したので、車両側部の強度部材の補強を兼ねるバッテリが、シートの下方つまり乗員着座位置の下方に対応して配設され、この結果、側突時における乗員保護性能の向上を図ることができる効果がある。

上述のフロントフロアパネル4およびバッテリ収納フロア9には、図2に示すように車両中央において車両前後方向に延びるトンネル部13が一体形成されており、バッテリ収納フロア9と対応するトンネル部13のリヤ側過半部はそれよりも車両前方側のトンネル部分に対して、そのトップデッキ部が低くなるように形成された低デッキ部13aに構成されている。
【0018】
上述の段差部8の直前位置においてフロントフロアパネル4上には車両左右両側部の強度部材としてサイドシル14,14間を車幅方向に連結するクロスメンバ15が設けられている。
【0019】
この実施例ではクロスメンバ15の車幅方向中央部にトンネル部13に対応する凹部15aを設け、単一のクロスメンバ15で左右のサイドシル14,14間を連結したが、トンネル部13の左側の立壁と左側のサイドシル14とを連結するクロスメンバ、トンネル部13の右側の立壁と右側のサイドシル14とを連結するクロスメンバの2部品により構成してもよい。

【0021】
ところで、図1に示すようにフロントシート19のシートバック20と左右横方向に略対向するように車両側部には強度部材としてのセンタピラー21が設けられている。
このセンタピラー21は車両上下方向に配設された強度部材で、図4に示す如くセンタピラーインナ22とセンタピラーアウタ23とを接合して、車両の上下方向に延びる閉断面24を有し、このセンタピラー21で下部のサイドシル14と上部のルーフサイド部とを上下方向に連結している。
【0022】
上述のトンネル部13の左右両側においてバッテリ収納フロア9の上部には電気モータ駆動用のバッテリ25,25が搭載されている。これら左右の各バッテリ25,25はフロントシート19の下方に対応する位置においてバッテリ収納フロア9に車幅方向に設けて搭載されており、その搭載構造は左右対称となっている。
【0023】
すなわち、図3、図4、図5に示すように、バッテリ25の左右の側面においてその前後両下部には1つのバッテリ25当り合計4つのL字状のブラケット26…を予め接合する一方、バッテリ収納フロア9にはスタッドボルト27…を予め立設固定し、ブラケット26のボルト挿通孔26a(図5参照)をスタッドボルト27に装着して、ナット28をスタッドボルト27に螺合することにより、バッテリ収納フロア9にバッテリ25を搭載したものである。
【0024】
しかも、図2、図4に示す如く2つのバッテリ25,25の車幅方向の両端部、つまり右側のバッテリ25の右端部と左側バッテリ25の左側部とはブラケット29,29を介してそれぞれ同側のセンタピラー21の基部に固定されている。
【0025】
上述のブラケット29は図5に示すように車幅方向に延びる天壁29aと、この天壁29aの前後に一体に折曲げ形成されて同方向に延びるビーム部29bとで門形状に構成されると共に、バッテリ25の上面に沿うフランジ部29cと、センタピラー21の基部に沿うフランジ部29dと、これらのフランジ部29c,29dを接続する連設フランジ29eとが一体に形成されたものである。
上述のフランジ部29cにはボルト挿通孔30,30を形成する一方、フランジ部29dにはボルト挿通用の長孔31,31を形成している。
【0026】
またバッテリ25の上面にはボルト挿通孔30…に対応する如く予めスタッドボルト32…を立設固定し、センタピラー21の基部にはレインフォースメント33に植設されたスタッドボルト34…を閉断面18内から挿通孔35を介して車内側へ臨設させている。ここで、上述のレインフォースメント33はセンタピラー21の基部において閉断面18内部側に予に接合され、またスタッドボルト34フランジ部29dの長孔31と対応する。
【0027】
而して図4に示す如く、ブラケット29の長孔31をスタッドボルト34に装着すると共に、ボルト挿通孔30をスタッドボルト32に装着して、ナット36,37を各スタッドボルト32,34に螺合することにより、バッテリ25,25の車幅方向の両端部をセンタピラー21の基部に連結固定したものである。
【0028】
上述のブラケット29による連結固定部位と対応して、2つのバッテリ25,25の相互間を、トンネル部13(詳しくは低デッキ部13a)を跨ぐ補強部材38で左右に連結している。
【0029】
この補強部材38は図2、図4、図5に示すようにトンネル部13の低デッキ部13a上方において車幅方向に延びるパイプ39と、このパイプ39の両端に接合フランジ40,40を介して一体的に接続された逆L字状のブラケット41,41とを備えている。
【0030】
上述のブラケット41には図5に示すようにボルト挿通用の長孔42,42を形成する一方、図4に示すようにバッテリ25,25側には長孔42に対応させて予めスタッドボルト43,43を接合し、左右の各ブラケット41,41の長孔42をスタッドボルト43に装着して、ナット44をスタッドボルト43に螺合することにより、左右のバッテリ25,25間を補強部材38で相互連結したものである。
【0031】
一方、図2、図3に示すようにバッテリ25の前部においては左右のバッテリ25,25の車内側の端部とトンネル部13とを補強部材45,45にて相互に連結している。
【0032】
つまり、パイプ46とフランジ部47と逆L字状のブラケット48とを備えた2つの補強部材45,45を設け、図2、図3に示すように左側のバッテリ25の右端部とトンネル部13の左側縦壁とを1つの補強部材45で相互連結し、右側のバッテリ25の左端部とトンネル部13の右側縦壁とを他の1つの補強部材45で相互連結している。
【0033】
ところで、上述の各バッテリ25,25の上方部は図1に示すようにクロスメンバ15とキックアップ部10との上部相互間に略水平状に張架されるプレート49により覆われるが、この実施例では該プレート49上にフロントシート19を配設する関係上、各ブラケット29,41には図5に示すように隆起部50,51が一体形成され、一方に隆起部50にはシートレール52連結用のスタッドボルト53を植設し、他方の隆起部51にはシートレール52連結用の取付け孔54を形成している。
【0034】
而して上述の各隆起部50,51には図1に示すようにプレート49を介してフロントシート19のシートレール52(詳しくはシートスライドレール取付け用のブラケット)が取付けられる。
【0035】
なお、図1において55はフロントサイドメンバ、56,57,58はクロスメンバ、59は燃料タンク、60は前車輪、61は後車輪であり、燃料タンク59内の燃料はエンジン/モータユニット7を内燃機関して用いる時に供給され、バッテリ25の直流電源はエンジン/モータユニット7をモータとして用いる時に電力供給される。
【0036】
このように上記構成の車両のバッテリ搭載構造によれば、上述のバッテリ25をフロアパネル(バッテリ収納フロア9参照)上に車幅方向に設けて、該バッテリ25の車外側の端部を車両側部の強度部材(センタピラー21参照)に固定したので、バッテリ25により車両側部の強度部材(センタピラー21参照)を補強することができる。
この結果、別途クロスメンバを追加することなく側突に対する車体剛性の向上を図って、側突時の車両変形を防止することができる効果があり、加えて、車両の最低地上高も有利となる効果があり、クロスメンバ追加による重量増加も招かない。
【0037】
しかも、上述の複数のバッテリ(この実施例では2つのバッテリ25,25)をトンネル部13の両側に配設し、両側に配設されたバッテリ25,25相互間を、トンネル部13を跨ぐ補強部材38で連結したので、車両両側部の強度部材(センタピラー21参照)間がバッテリ25と補強部材38とで車幅方向に連結され、これら両者(バッテリ25、補強部材38)がクロスメンバと同様の作用を奏する。
また、トンネル部13の左右両側のデッドスペースを有効利用してバッテリ25を配設することができ、車室内の空間の有効利用を図りつつ、バッテリ容量を増加することも可能となる効果がある。
【0038】
さらに、上述の複数のバッテリ25,25の車幅方向の両端部を、車両上下方向に配設されたピラー(センタピラー21参照)の基部に固定したので、バッテリ25を側突時のピラー内倒れ防止用の補強部材として有効利用し、ピラー(センタピラー21参照)の内倒れを阻止することができる効果がある。
【0039】
加えて、車幅方向に配設された上述のバッテリ25を、シート(フロントシート19参照)の下方に対応した位置に配設したので、車両側部の強度部材(センタピラー21参照)の補強を兼ねるバッテリ25が、シート(フロントシート19参照)の下方つまり乗員着座位置の下方に対応して配設され、この結果、側突時における乗員保護性能の向上を図ることができる効果がある。
【0040】
また実施例で示したように、車幅方向に延びるビーム部29bを備えたブラケット29で、バッテリ25の車外側の端部とセンタピラー21の基部とを連結固定すると、このビーム部29bが側突荷重に対抗するので、側突時の車両変形をより一層良好に防止することができる効果がある。
【0041】
図6、図7は車両のバッテリ搭載構造の他の実施例を示し、図5で図示したブラケット29に代えて他のブラケット62を用いるものである。
このブラケット62は図7に拡大して示すように、バッテリ25の上面に沿う底部63と、センタピラー21の基部に沿う側部64と、車幅方向に延びる前後一対の略三角形状のガセット部65,65とを一体形成したもので、低部63にはスタッドボルト32に対応するボルト挿通孔66を形成する一方、側部64にはスタッドボルト34に対応するボルト挿通用の長孔67を形成している。
【0042】
図5に示すブラケット29に代えて図7のブラケット62を用いても、ガセット部65,65が側突荷重に対抗するので、側突時の車両変形をより一層良好に防止することができる効果がある。
なお、その他の点については先の実施例とほぼ同様の作用、効果を奏するので、図6において前図と同一の部分には同一符号を付して、その詳しい説明を省略する。
【0043】
