Abstract
Description
例えば、図14(a)に示すように、特許文献1には、サイドコンプ100が、車内側に位置するルーフサイドインナ110と、当該ルーフサイドインナ110の車外側に位置するルーフサイドアウタ120とを有しており、ルーフサイドインナ110の車内側にルーフアーチ130の車幅方向外側端部が固定され、ルーフサイドアウタ120の車外側にルーフパネル140の車幅方向外側端部が固定された発明が従来例として挙げられている。
前記問題を解決するものとして、図15(a)及び(b)に示すように、特許文献2には、ルーフアーチ300が、ルーフレールアウタ310とルーフレールインナ320とを閉断面を成すように結合して構成されており、また、サイドコンプ350(詳しくはルーフサイドインナ360の上面)に、閉断面を成すように結合したエクステンション部材330及びピラーリインフォース部材340を固定した発明が開示されている。
また、かかる構成によれば、後側アーチフランジ部をアーチロア及びアーチアッパの両方で形成するため、後側アーチフランジ部の強度を高めることができる。
また、かかる構成によれば、後側レールフランジ部をルーフサイドインナ及びルーフサイドスティフナの両方で形成するため、後側レールフランジ部の強度を高めることができる。
一方、アーチ側結合部が下方から上方に向かうにつれて車幅方向内側に位置するように傾斜した場合、アーチ側結合部とレール側結合部との合わせ面が傾斜することになり、ルーフコンプ及びサイドコンプの組付時において、ルーフコンプの下方への移動とサイドコンプの車幅方向内側への移動を同時に行う必要があるため、両者の組み付け作業が煩雑になる。
そこで、アーチ側結合部が鉛直方向に沿って延在し、かつレール側結合部がアーチ側結合部に対して平行に延在することにより、両者の合わせ面が鉛直になるため、ルーフアーチの成形性が良好になると共に、サイドコンプをルーフコンプに向けて車幅方向に移動し、レール側結合部をアーチ側結合部に突き当てて車幅方向位置を決定した後に、ルーフコンプを上下移動して位置調整することができるようになるため、ルーフコンプの下方への移動とサイドコンプの車幅方向内側への移動を同時に行う必要がなくなり、両者の組み付け作業が簡便になる。
そこで、ルーフサイドレールとルーフアーチとの交差部分である前側レールフランジ部と後側レールフランジ部との間において、結合部が設けられており、この結合部を介して、ルーフサイドインナ及びルーフサイドスティフナが結合されることにより、当該交差部分においても、ルーフサイドインナとルーフサイドスティフナとを直接結合できるため、ルーフサイドレールの閉断面剛性が高まる。
また、説明において方向を示すときは、車両の前後左右上下を基準にして説明する。なお、「車幅方向」と「左右方向」は同義である。
図1に示すように、本実施形態の車体構造1は、車体の左右両側に設けられ車体側部を構成する一対のサイドコンプ2,2と、車体上部を構成するルーフコンプ3とを連結するための構造である。
なお、サイドコンプ2,2は、左右対称となっているため、以下の説明においては左側のサイドコンプ2のみを説明し、右側のサイドコンプ2の説明は省略する。
ルーフサイドレール20は、図4に示すように、ルーフサイドインナ21と、ルーフサイドスティフナ22と、ルーフサイドアウタ23と、を有する。また、ルーフサイドレール20は、図3に示すように、前側レールフランジ部24と、後側レールフランジ部25と、載置部26と、を有する。
前側レールフランジ部24及び後側レールフランジ部25は、請求の範囲でいう「第2フランジ部」に相当する。
なお、本実施形態では、本発明の車体構造1を、最も前方に位置するルーフアーチ4とサイドコンプ2との連結部分に適用した場合を例にして説明する。また、ルーフコンプ3は、左右対称となっているため、以下の説明においては左側のみを説明し、右側の説明は省略する。
なお、図9(a)乃至(c)は、実施形態に係る車体構造1の組付工程を説明するための図4相当の断面図であり、(d)乃至(f)は、実施形態に係る車体構造1の組付工程を説明するための図5相当の断面図である。
このとき、図9(d)に示すように、ルーフサイドレール20の後側レールフランジ部25は、ルーフアーチ4のフランジ延長部42d及びルーフパネル5のフランジ部52の下方に位置している。
また、図9(e)に示すように、ルーフサイドレール20の後側レールフランジ部25は、ルーフアーチ4の後側アーチフランジ部44の下方に位置する。
更に、ルーフサイドレール20の前側レールフランジ部24は、ルーフアーチ4の前側アーチフランジ部43の下方に位置する(図8(b)参照)。
また、ルーフアーチ4の前側アーチフランジ部43は、ルーフサイドレール20の前側レールフランジ部24に当接して係止される(図8(b)参照)。
したがって、ルーフパネル5がルーフサイドレール20に載置され、かつルーフアーチ4がルーフサイドレール20に当接して係止されるため、サイドコンプ2に対するルーフコンプ3の下方への移動が規制される。
また、図9(f)に示すように、後側アーチフランジ部44のボルト挿通孔41j,41lと、後側レールフランジ部25のボルト挿通孔21m,22iにボルトBを挿通してナットNに螺合することにより、両者を接合する。
更に、ルーフパネル5の前端部5Bの車幅方向外側の端部5B1と、ルーフアーチ4の前側アーチフランジ部43と、ルーフサイドレール20の前側レールフランジ部24とを溶接で一体的に接合する(図8(b)参照)。
また、後側アーチフランジ部44をアーチロア41及びアーチアッパ42の両方で形成するため、後側アーチフランジ部44の強度を高めることができる。
