Description

【０００１】
【発明の属する技術分野】
本発明は、自動車のパネル間に補強メンバを追加して外力に対する車体強度を大きくすることができる車体の補強構造に関する。
【０００２】
【従来の技術】
図８は、自動車の左側に位置するサイドボディアウタパネル１を示す。サイドボディアウタパネル１の前部には、ルーフを支持するフロントピラー（Ａピラー）部２が設けられ、その車室側にはドアヒンジパネル３が溶接により固着され、サイドボディアウタパネル１のサイドシル部４にはサイドシルアウタパネル５が溶接により固着される。なお、図８中の矢印Ｆは車体の前方を示し、矢印ＩＮは車室側を示す（他の図においても同様である）。
図９は、上記の各パネルを組付けた状態の図８のＷ−Ｗ線方向における断面図である。図に示すように、フロントピラー部２の下部は、サイドボディアウタパネル１とダッシュサイドパネル６で形成された閉空間であり、それらのパネル間にはサイドボディアウタパネル１の内側に沿ってドアヒンジパネル３が配設されている。
【０００３】
【発明が解決しようとする課題】
図９に示すフロントピラー部２の前側にはタイヤの前輪が位置し、フロントピラー部２に前方からの外力が入力されたときにフロントピラー部２が車体後方側に変形するおそれがある。この変形を防止するために、例えば補強メンバを追加して、フランジ部７ａ，７ｂに別途補強メンバを挟持させることが考えられるが、フランジ部７ａ，７ｂに補強メンバを１枚追加すると、スポット溶接をするパネルが４枚となり、溶接不可となるおそれがある。
さらに、サイドシル部４では、前方からの外力が入力されたときに、サイドシル部４が車体外側の斜め上方に変形するおそれも考えられる。
本発明は上記課題に鑑みてなされたもので、パネルの溶接可能な範囲内で車体の補強構造を提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記目的を達成するために本発明は、サイドボディアウタパネル及び車室側パネル間に、ドアヒンジパネルとサイドシルアウタパネルとが設けられ、上記ドアヒンジパネルが上記サイドボディアウタパネルのフロントピラー部に配設され、上記サイドシルアウタパネルの前端部が上記ドアヒンジパネルの下部に接合されるとともに上記サイドボディアウタパネルのサイドシル部に配設され、上記ドアヒンジパネル及びサイドシルアウタパネルの接合体が上記サイドボディアウタパネルと上記車室側パネルとの重合部でスポット溶接される車体の補強構造において、上記ドアヒンジパネルの下端側及び上記車室側パネル間には、横断面がコ字形であり、その下部が車両後方向に延設した側面視で略Ｌ字形状であり、かつ縦断面が縦部と車両下側の底部からなるＬ字形であるドアヒンジ補強メンバを設け、上記ドアヒンジパネル及びサイドシルアウタパネルと上記サイドボディアウタパネルとの間には、上記ドアヒンジパネルとサイドシルアウタパネルとの接合部を跨ぎ、かつ上記ドアヒンジ補強メンバの縦部と底部に接合されたサイドシル補強メンバを設けている。
【０００５】
【発明の実施の形態】
以下、本発明の実施の形態による車体の補強構造について、図面を参照しながら説明する。なお、従来と同じ構成部材については同一の符号を付して説明する。
図１は、本発明に係る車体の補強構造を示し、この補強構造はフロントピラー部２の下部とサイドシル部４を強化するものである。車体の側部に配設されるサイドボディアウタパネル１の前部には、ルーフ（一部のみ示す）１ａを支持するフロントピラー部２が設けられ、そのほぼ中央より下部にはドアヒンジパネル３がサイドボディアウタパネル１の室内側に配設される。また、サイドシル部４には、サイドシルアウタパネル５がサイドボディアウタパネル１の車室側に配設される。
【０００６】
図２は、図１のフロントピラー部２とサイドシル部４との接合部を示し、サイドボディアウタパネル１を除いて、車体の外側から見た図であり、図３は図２のＸ−Ｘ線方向における断面図である。
図３に示すように、フロントピラー部２の下部は、サイドボディアウタパネル１と車室側パネルであるダッシュサイドパネル６とにより袋状（閉断面）に形成されている。サイドボディアウタパネル１は断面がハット形状であり、ドアヒンジパネル３はサイドボディアウタパネル１と同じくその内面に沿ったハット形状に形成され、それらの両側縁部がダッシュサイドパネル６の縁部とでフランジ部７ａ，７ｂを形成し、３枚のパネル重合部にスポット溶接ａ，ｂがされている。サイドシルアウタパネル５は、図２に示すように端部がドアヒンジパネル３の端部に接合されている。
【０００７】
本実施の形態では、図１に示すドアヒンジ補強メンバ８とサイドシル補強メンバ９が、上記した従来の構成に追加されている。図４はドアヒンジ補強メンバ８の斜視図であり、基本形状がほぼＬ字形のドアヒンジ補強メンバ８は、フロントピラー部２の下部からサイドシル部４にわたって配設され、かつドアヒンジパネル３の車室側に配設され、フロントピラー部２に位置する部位の両側部にはフランジ８ａ，８ｂが形成されている。図３に示すようにドアヒンジ補強メンバ８は、サイドボディアウタパネル１とダッシュサイドパネル６とで形成する閉空間に配設され、そのフランジ部８ａ，８ｂがドアヒンジパネル３の内面に重ねられ、それらのパネル重合部にスポット溶接ｃ，ｄがされている。
【０００８】
図５は、図２のＹ−Ｙ線方向の断面図である。フロントピラー部２とサイドシル部４との会合部に設けたコーナ部には、サイドボディアウタパネル１とダッシュサイドパネル６との間にドアヒンジパネル３の上縁部が配設され、それらの３枚のパネル重合部にスポット溶接ｅがされている。また、その下縁部では、サイドボディアウタパネル１とサイドシルインナパネル１１との間にドアヒンジパネル３が配設され、これら３枚のパネル重合部にスポット溶接ｆがされている。
【０００９】
ドアヒンジパネル３の下部には、車幅方向外側に突出する凸部３ａが形成され、この凸部３ａの外面には図６に示す上下方向断面がハット形状のサイドシル補強メンバ９の前端部が配設されている。また、ドアヒンジパネル３の車室側にはドアヒンジ補強メンバ８が配設され、サイドシル補強メンバ９の上下部に形成されたフランジ部が位置する３枚のパネルの重合部にスポット溶接ｇ，ｈがされている。また、ドアヒンジパネル３の凸部３ａではドアヒンジパネル３とサイドシル補強メンバ９のパネル重合部にスポット溶接ｍがされている。
図７は、図２のＺ−Ｚ線方向の断面図である。図に示すようにサイドシル部４では、サイドボディアウタパネル１と車室側パネルであるサイドシルインナパネル１１との間にサイドシルアウタパネル５が配設され、各々の上下端部で３枚のパネル重合部にスポット溶接ｉ，ｊがされている。サイドシルアウタパネル５の外面には、サイドシル補強メンバ９が配設され２枚のパネル重合部にスポット溶接ｋ，ｌがされている。図７中の１２はフロアパネルを示し、サイドシルインナパネル１１と溶接されている。
【００１０】
上記の各パネルを組付けるときは、予めドアヒンジパネル３にドアヒンジ補強メンバ８を固定し、次いでドアヒンジパネル３をサイドシルアウタパネル５及びサイドシル補強メンバ９にスポット溶接により固定する。図４に示すように、ドアヒンジ補強メンバ８には、スポット溶接ガンの治具クランプ用孔８ｃとスポットガンのチップ挿入用孔８ｄ及び２個の治具孔８ｅが穿設され、凸部３ａのスポット溶接ｍを容易にしている。なお、これらの孔８ｃ〜８ｅはドアヒンジ補強メンバ８を電着液に浸漬したときの循環効果もある。
【００１１】
本実施の形態では、ドアヒンジ補強メンバ８の上下方向における断面（横断面）がコ字形であり、その下部では車両前後方向における断面（縦断面）がＬ字形である。このため、前方から外力が加わったときにフロントピラー部２及びサイドシル部４の剛性が大きくなっている。ドアヒンジ補強メンバ８の前後に形成したフランジ８ａ，８ｂは、ドアヒンジパネル３とドアヒンジ補強メンバ８の断面積が大きくとれる構造になっている。サイドシル補強メンバ９をサイドシル部４に取付けたので、サイドシル部４が車体の上方外側に変形するのを防止することができる。このサイドシル補強メンバ９は、図２に示すように線対称形にしてあることから、車体の左右共通の部品として使用できる。ドアヒンジ補強メンバ８及びサイドシル補強メンバ９を用いないときは、サイドボディアウタパネル１、ドアヒンジパネル３及びサイドシルアウタパネル５のスポット溶接箇所が従来と同じである。そのため、ドアヒンジ補強メンバ８及びサイドシル補強メンバ９を車両に使用するか否かの使い分けができる。
【００１２】
以上、本発明の実施の形態について説明したが、勿論、本発明はこれに限定されることなく本発明の技術的思想に基いて種々の変形及び変更が可能である。
【００１３】
【発明の効果】
以上述べたように、本発明によれば、ドアヒンジパネルの下端側及び車室側パネル間にはドアヒンジ補強メンバを設け、上記ドアヒンジパネル及びサイドシルアウタパネルとサイドボディアウタパネルとの間には、上記ドアヒンジパネルとサイドシルアウタパネルとの接合部を跨いでサイドシル補強メンバを設けたので、フロントピラー部に前後方向からの外力、またはフロントピラー部を軸とした回転方向の外力が入力される際に、フロントピラー部のパネルの変形を防止することができる。
上記ドアヒンジパネル、上記ドアヒンジ補強メンバ及び上記サイドシル補強メンバの３枚のパネルを上記重合部以外の箇所で、スポット溶接したので同一ボディで補強メンバの仕様分けができる。
上記サイドシル補強メンバを前後中心線に対して対称形にしたので、車体の左右共通箇所で使用できるようになった。このため、部品点数の削減と生産コストの低減を図ることができる。
上記ドアヒンジ補強メンバに、上記スポット溶接用ガンのチップ挿入孔を形成したので、スポット溶接が容易になるとともに、電着液に浸漬したときに液の循環が良くなるという付加的効果もある。
