【発明の属する技術分野】
本発明は車体前部構造に関し、特に、自動車等の車両において衝突時に衝突体を保護する車体前部構造に関する。
【０００２】
【従来の技術】
従来、車体前部構造においては、アウタパネルにインナパネル（インナフレームともいう）を一体化した自動車のフード（ボンネットともいう）において、インナパネルをプレス成形した一枚物の成形品とすると共に、このインナパネルの軽量化及びフード剛性向上のために開口部が形成した構成が知られている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特開平１１−３２１７１４号公報（図５、図６、図７）
【０００４】
【発明が解決しようとする課題】
しかしながら、前記特許文献１では、インナパネルの開口部の縁部をアウタパネルの裏面に接着することで閉断面構造を形成し、フード剛性を向上させているものの、衝突体がフードの前部領域に衝突した場合には、衝突位置の車幅方向の違いによらず衝突体への衝突荷重を均一にする構成にはなっていない。
【０００５】
本発明は上記事実を考慮し、衝突体がフードの前部領域に衝突した場合に、衝突位置の車幅方向の違いによらず衝突体への衝突荷重を均一にできる車体前部構造を提供することが目的である。
【０００６】
請求項１記載の本発明は、車体外側面を構成するフードのアウタ部材と、前記アウタ部材の内側に配設され少なくとも一つ以上の開口部を有するフードのインナ部材と、からなる車両用フードと、
フロントバンパーと、
を備えた車体前部構造であって、
前記フードのインナ部材は、前記フードのインナ部材の車幅方向に沿った前端部を構成し、前記開口部の前方周縁部となると共に後端部の平面視における形状が車幅中央部が車体前方へ凹の弓形線状となったインナフロントと、前記フードのインナ部材の後端部を構成し、前記開口部の後方周縁部となるインナリヤと、前記フードのインナ部材の車幅方向両端部を構成し、前記開口部の側方周縁部となるインナサイドと、これらのインナサイドの間に設けられ前記開口部の側方周縁部となると共に前記インナフロントと分割構造とされ、前記インナフロントに接合された少なくとも１つのインナセンターと、
を有し、前記車体前部の車幅方向における全ての位置での側面断面において、前記フロントバンパーの先端部位から前記開口部の前端縁部までの車体の外形に沿う長さが略一定であることを特徴とする。

【０００８】
請求項２記載の本発明は、請求項１記載の車体前部構造において、前記フロントバンパーの先端部位から前記開口部の前端縁部までの長さは、車体の外形に沿う円弧状の曲線の線長であることを特徴とする。
【０００９】
従って、車体前部の車幅方向における全ての位置での側面断面において、フロントバンパーの先端部位から、車両用フードのアウタ部材の内側に配設され少なくとも一つ以上の開口部を有するインナ部材の開口部の前端縁部までの長さが、車体の外形に沿う円弧状の曲線の線長であり、略一定であるため、上下に長尺状の衝突体がフロントバンパーの車幅方向のどの位置に当接した場合にも、前記衝突体の最上部が当接するフード上面の位置と、フード剛性が変化する開口部の前端縁部との車体外形に沿う長さを略均一にできる。この結果、衝突体がフードの前部領域に衝突した場合に、衝突位置の車幅方向の違いによらず衝突体への衝突荷重を均一にできる。
請求項３記載の本発明は、請求項１又は請求項２に記載の車体前部構造において、前記少なくとも１つのインナセンターには前端部から車体前側下方に向かって延設部が形成されており、前記延設部の前端縁部が前記インナフロントの前フランジに接合されていることを特徴とする。
従って、少なくとも１つのインナセンターに、その前端部から車体前側下方に向かって形成された延設部の前端縁部がインナフロントの前フランジに接合されることで、アウタ部材とインナ部材とを有するフード前端部の剛性が上がる。
【００１０】
【発明の実施の形態】
本発明における車体前部構造の一実施形態を図１〜図３に従って説明する。
【００１１】
なお、図中矢印ＵＰは車体上方方向を示し、図中矢印ＦＲは車体前方方向を示している。
【００１２】
図３に示される如く、本実施形態では、自動車のフード１０が、フード１０の車体外側面を構成するアウタ部材としてのアウタパネル１２と、アウタパネル１２の内側に配設されエンジンルーム側部を構成するインナ部材としてのインナパネル１４で構成されている。
【００１３】
図２に示される如く、フード１０のインナパネル１４は、インナパネル１４の前端部を構成するインナフロント１６、インナパネル１４の後端部を構成するインナリヤ１８、インナパネル１４の車幅方向両端部を構成するインナサイド２０、及び左右のインナサイド２０の間に車体前後方向に沿って配設され、インナフロント１６とインナリヤ１８とに架設された３本のインナセンター２２で構成されている。
【００１４】
図３に示される如く、３本のインナセンター２２の後端部２２Ａは、インナリヤ１８の前フランジ１８Ａの上面に接合されており、３本のインナセンター２２の前端部２２Ｂは、インナフロント１６の後フランジ１６Ａの上面に接合されている。なお、車幅方向中央部に配設されたインナセンター２２においては、前端部２２Ｂから車体前側下方に向かって延設部２２Ｃが形成されており、延設部２２Ｃの前端縁部２２Ｄは、インナフロント１６の前フランジ１６Ｂの前面に接合されている。
【００１５】
図１に示される如く、インナパネル１４には、車体前後方向に沿って並行に配設された直線状の左右のインナサイド２０と３本のインナセンター２２とによって、車体前後方向に延設された４つの開口部３０が形成されている。
【００１６】
また、開口部３０の前端縁部３０Ａを構成するインナフロント１６の後端縁部１６Ｃの平面視における形状は、車幅方向中央部が車体前方へ凹となった弓形線状となっており、本実施形態の車体では、車幅方向における全ての位置での側面断面において、図３に示される如く、開口部３０の前端縁部３０Ａからフロントバンパー４０の先端部位としての前部下端４０Ａまでの長さＬが略一定Ｌとなっており、フロントバンパ−４０の前部下端４０Ａから開口部３０の前端縁部３０Ａまでの長さＬは、車体の外形に沿う円弧状の曲線の線長となっている。なお、インナフロント１６の前端縁部１６Ｄの平面視における形状は、車幅方向中央部が車体前方へ凸となった弓形線状となっている。
【００１７】
次に、本実施形態の作用を説明する。
【００１８】
本実施形態では、図１に示される如く、インナパネル１４に形成された開口部３０の前端縁部３０Ａが、車幅方向中央部が車体前方へ凹となった弓形線状に設定されており、図３に示される如く、本実施形態の車体では、車幅方向における全ての位置での側面断面において、開口部３０の前端縁部３０Ａからフロントバンパー４０の前部下端４０Ａまでの長さＬが略一定となっている。
【００１９】
この結果、フロントバンパー４０の前部下端４０Ａの地上高をＨとすると、本実施形態の車体では、車幅方向における全ての位置での側面断面において、開口部３０の前端縁部３０Ａからフロントバンパー４０を介して路面Ｒに達する長さＬ＋Ｈが略一定になる。
【００２０】
このため、路面Ｒ上に存在する上下方向に長尺状の衝突体が、フロントバンパー４０の車幅方向のどの位置に当接した場合にも、衝突体の上部が当接するフード上面の位置と、開口部３０の前端縁部３０Ｂとの長さを略均一にできるので、衝突体の上部がフード１０の前部領域に衝突した場合に、衝突体の上部への衝突荷重を均一にできる。
【００２１】
また、本実施形態では、インナフロント１６の後端縁部１６Ｃの平面視における形状が、車幅方向中央部が車体前方へ凹となった弓形線状となっており、インナフロント１６の前端縁部１６Ｄの平面視における形状が、車幅方向中央部が車体前方へ凸となった弓形線状となっているため、インナフロント１６の車体前後方向の幅が略一定になる。この結果、インナフロント１６の成形時の歩留まりが向上し生産性が向上すると共に運搬や保管のスペースが小さくなり、運搬費や管理費の低減が可能になる。
【００２２】
以上に於いては、本発明を特定の実施形態について詳細に説明したが、本発明はかかる実施形態に限定されるものではなく、本発明の範囲内にて他の種々の実施形態が可能であることは当業者にとって明らかである。例えば、上記実施形態では、フード１０のインナパネル１４に開口部３０を４つ形成したが、開口部の数は４つに限定されず一つ以上何個でも良い。
【００２４】
