【発明の属する技術分野】
本発明は自動車の車体前部構造に関する。
【0002】
【従来の技術】
近年、車体の組立工程の簡略化と組付作業の自動化等を狙って、ラジエータコアサポートメンバにヘッドランプユニットやフロントバンパー等をサブアッセンブリして所謂フロントエンドモジュールを構成し、車体の組立ラインで該フロントエンドモジュールを車体前部に組付けるようにしている。
【0003】
また、前述のラジエータコアサポートメンバは、車体前部のデザイン上の要求から、そのアッパメンバの左右両側部のサイド部を後方に向けて張り出させて、該サイド部とその下方に設けられたランプ取付部との間にヘッドランプユニットを装着して、該ヘッドランプユニットがフロントフェンダ側に廻り込むような配設レイアウトを採用することが行われている。
【0004】
【発明が解決しようとする課題】
前述のようにラジエータコアサポートメンバのアッパメンバの左右両側部のサイド部が後方に向けて角状に張り出しているため、輸送、搬送時の荷姿が悪く嵩張ってしまう不具合を生じる。
【0005】
また、このようにサイド部が後方へ張り出しているため成形精度が出しづらくなってしまうばかりでなく、大型の塗装装置が必要となってしまう。
【0006】
更には、フロントエンドモジュールの車体前部への取付けは、前述のラジエータコアサポートメンバのサイド部を車体前部上側の左右のフードリッジメンバに締結固定すると共に、該ラジエータコアサポートメンバの左右のサイドスティ部を車体前部下側の左右のサイドメンバに締結固定することによって行われるが、フードリッジメンバおよびラジエータコアサポートメンバの成形誤差や組付誤差によって、前記アッパメンバのサイド部をフードリッジメンバの前端部に締結固定した際に、該サイド部に前後方向の撓み変形が生じると、このサイド部の下側のランプ取付部に組付けられたヘッドランプユニットの組付姿勢が変化して、車体前部に対するヘッドランプユニットの合わせ精度が悪化してしまう不具合を生じる。
【0007】
そこで、本発明はラジエータコアサポートメンバの輸送、搬送時における荷姿をコンパクトにすることができると共に、フロントエンドモジュールを車体前部に組付けた際に、車体前部とヘッドランプユニットとの合わせ精度を高めることができる自動車の車体前部構造を提供するものである。

【0035】
以上の実施形態の構造によれば、アッパメンバ2の左右両側部のサイド部3を別体成形して、該アッパメンバ2とランプ取付部6との連設部に取付けるようにしてあるため、ラジエータコアサポートメンバ1の輸送、搬送時には後方に張り出すこのサイド部3を外してコンパクトな荷姿にすることができ、輸送、搬送効率を高めることができる。
【0036】
また、ラジエータコアサポートメンバ1の本体部分と前記サイド部3とを別成形することによってこれらの成形精度を高められると共に塗装作業性を向上することができる。
【0037】
そして、前記サイド部3は前後方向に位置調整自在に取付けることができるため、ラジエータコアサポートメンバ1のランプ取付部6に図外のヘッドランプユニットをサブアッセンブリしてフロントエンドモジュールを構成し、該フロントエンドモジュールを車体前部に組付ける際に、車体前部のフードリッジメンバと、これに結合する前記サイド部3との相互に前後方向の位置づれが生じていた場合でも、該サイド部3をラジエータコアサポートメンバ1の本体部分に対して前後方向に位置調整することによって前記位置づれを吸収でき、この結果、サイド部の撓み変形に伴うヘッドランプユニットの組付姿勢の変化を生じることがなく、車体前部に対するヘッドランプユニットの合わせ精度を高めることができる。
【0038】
ここで、特に本実施形態では前記ランプ取付部6を別体の合成樹脂製としてあるため、ヘッドランプユニットを締結固定するランプ取付座13の位置精度を高く成形でき、ヘッドランプユニットの組付姿勢を安定化することができる。
【0039】
また、このランプ取付部6を介してアッパメンバ2とサイドスティ部5とを結合するため、樹脂成形された成形精度の高い該ランプ取付部6を基準にしてアッパメンバ2、サイド部3、およびサイドスティ部5を組付けることによって、これら部材の組付精度を高めることができる。
【0040】
更に、前記サイド部3を金属材料からなる閉断面構造としてあってその剛性・強度を高められることと併せて、アッパメンバ2およびロアメンバ4も共に別体成形してあるため、ラジエータコアサポートメンバ1の全体的な成形精度を高められて、車体前部に対する合わせ精度を高めることができる。
【0041】
また、本実施形態では、サイドスティ部5はランプ取付部6を介してアッパメンバ2に締結固定されるようにしたが、これに限らず、サイドスティ部5を直接アッパメンバ2に締結固定してもよい。さらに、ロアメンバ4とサイドスティ部5は、金属材料からなる強度の高い構造であるので、左右のサイドメンバSB前端間を強固に締結固定することができる。
