Description

【0001】
【発明の属する技術分野】
本発明は自動車等の車体の開口部を開閉するバックドアやフロントフード等の車両用扉開閉構造に関するものである。
【0002】
【従来の技術】
従来、自動車の後部に上下開閉可能に取り付けられた、車両用扉の一種である跳ね上げ式バックドアにおいて、図5に示すように、車体110の後部開口部の左右両縁上部108から後方へ差出されたバックドアダンパー102は、バックドアダンパーブラケット104を介して、バックドア100のインナパネルの左右両縁上部を支持することとなっている。
【0003】
そして、バックドアの開閉時に、バックドアと車体後部との衝突によるドア見切り干渉等を防止するための緩衝機構は、バックドア左右両縁の各々の中央付近にクッションゴムなどの緩衝部材を設けて構成されているが、図5及び図6に示すように、意匠上の理由で、緩衝部材106が配置される空間がバックドアダンパー102の下側に確保できないときは、緩衝部材106はバックドアダンパーブラケット104の横側に設けられ、ドア見切り干渉等を防止することとなる。
【0004】
また、図7に示すような開閉扉の緩衝機構は、実開平5−58430号公報で提案されており、この構成の緩衝機構では、バックドアダンパー103は、車体の後部開口部の左右両縁上部111に自らの根端部105がスタットボルト109により取り付けられ、三次元的に回転可能に保持され、根端部105の上側にクッションゴム等から形成された円柱形の緩衝部材107が止着されている。そして緩衝部材107は、バックドア101の開閉時、バックドア101側当接面113に接し、衝撃を吸収することとなる。
【0005】
【発明が解決しようとする課題】
しかしながら、図5及び図6に示すような従来技術では、緩衝部材106がダンパー102の横側に設定され、バックドア開口フランジ112とドア見切り114間の距離Lが大きくなるため、バックドア100の開口が狭くなるという問題点があった。また、実開平5−58430号公報で提案されている緩衝機構では、バックドアダンパー103の一端105に緩衝部材107を設けているので、緩衝部材107が倒れ易く、変形し易くなるという問題点や、バックドア101開閉時の衝撃が緩衝部材107のみならずバックドアダンパー103へも伝わり、ねじれによりバックドアダンパー103が変形してしまうという問題点があった。
【0006】
本発明は、上記課題を解決するためになされたものであり、十分なバックドア開口を確保でき、従来より緩衝部材の強度を高くすることができる車両用扉開閉構造を提供することを目的とする。
【0007】

【0015】
【発明の実施の形態】
以下、本発明を具体化した車両用扉開閉構造の一実施形態について、自動車のバックドアを例に挙げ、図面を参照しつつ説明する。ここで、図1は、本発明の実施形態を示す、車両の後方右側からの斜視図であり、図2は、図1に示すダンパーブラケット本体の斜視図であり、図3は、バックドアが閉じた状態での、図2におけるA−A線における矢視方向断面図である。また、図4は、本発明の変形例の1つを示す、ダンパーブラケット本体の斜視図であり、図5は、従来技術の車両用扉開閉構造を示す車両の後方右側からの斜視図であり、図6は、図5のB−B線における矢視方向断面図であり、図7は、実開平5−58430号公報で提案された自動車のバックドアの開閉構造を示す斜視図である。
【0016】
尚、本発明の実施の形態では、一般的に自動車が左右対称な形状であるという性格上、車両および車体、車体に係る部品の説明は車両の右側側面においてのみ行い、左側側面に関しての詳細な説明は省略しているが、左側側面も同様の機構となっている。
【0017】
まず、図1を参照して自動車30の車体25の構造を説明する。図1に示すように、後部開口部20を備えた自動車30において、車体25の後部には、上下開閉可能な状態にバックドア1が設けられている。そして、その上下方向への開閉運動を司るのが、図示外のバックドアヒンジと、ダンパステー5であり、バックドアヒンジは、車体25側に不動に固定されるベースの部分と、バックドア1側に、ベース部分と回転可能に保持された腕となるアームの部分とから構成され、バックドア1を開閉可能に保持し、またダンパステー5は、その内部に封入した流体により、バックドア1の開閉運動の制動を行う。
【0018】
ダンパステー5は、車体後部開口部の左右両縁上部3から差出され、ダンパステー5のバックドア側端部に回動可能に結合されたダンパーブラケット2により、バックドア1の左右両縁の各々の中央付近に連結されている。ダンパーブラケット2には緩衝部材10が一体成形されており、緩衝部材10はバックドアが閉じたときに、車体後部開口部の左右両縁上部3上の車体側当接面11に当接して衝撃を吸収する。
【0019】
次に、図2を用いてダンパーブラケット2の構造について説明する。ダンパーブラケット2は、固定部であるバックドア取り付け面6と、その取り付け面6が曲折されて形成されたダンパー取り付け面8とを有し、断面が略L字型の形状となっており、バックドア取り付け面6上には、ダンパーブラケット2をバックドアへ取り付けるためのボルト等を通す、小判型の貫通孔6aと円形の貫通孔6bが設けられている。
【0020】
ダンパー取り付け面8にはダンパステー5が自在継ぎ手40を介して連結され、ダンパー取り付け面8の一部は、芯部として扁平した円錐台状のゴム等の弾性体から成る緩衝部材10に貫入されており、円錐台状の緩衝部材10の底面10cは、バックドア取り付け面6と段差の無いように成型されている。芯部は、緩衝部材10が車体25に当接する方向に延出する基部8aと、基部8aの先端から、緩衝部材10の車体25との当接面10aに対し平行に延出する先端部8bとを備えている。この芯部により、緩衝部材10の倒れや座屈等による変形を防ぐことができる。尚、緩衝部材側当接面10aに形成された突起部10bは、バックドア1開閉時に緩衝部材10と車体25との当接面10a、11で生じる剥離等を防止するためのものである。
【0021】
図3は、バックドア1が閉じた状態でのダンパーブラケット2と車体25との関係を断面図で示したものである。ダンパーブラケット2は、バックドア1のインナパネル1aとバックドア1の補強材であるバックドアリーンホース50に重なり、ボルト51とナット52で挟み込まれて固定されている。ダンパーブラケット2に一体に成形された緩衝部材10はその底面10cが、バックドア1のインナパネル1aに当接するように成型されている。また、ダンパー取り付け面8が緩衝部材10に貫入された芯部の先端部8bが、緩衝部材側当接面10aを緩衝部材10内部で支持している。
【0022】
また、この図3に示す断面図における車体側の形状では、車体側当接面11が平坦になるように成型されており、車体側当接面11を後部開口部20方向へ延設し、車体25後部方向へ曲折して後部開口フランジ15が形成され、その先端には外部からの水や埃などを遮断するウェザストリップ53が設けられている。
【0023】
以上に説明した車両用扉開閉構造を備えた自動車30では、ダンパーブラケット2の後部開口フランジ15と、車体25右側側面が後部開口部20方向へ曲折した部分の、車体25側面における最後部の稜線であるドア見切り13との距離lは、図6に示す従来技術における後部開口フランジ112とドア見切り114間の距離Lよりも短縮され、それにより後部開口が広くとれ、ダンパーブラケット2近傍の空間が有効に利用できる。そして緩衝部材10は、バックドア1のインナパネル1aに当接するように成型されているので、緩衝部材10の車体側当接面11だけでなく、バックドア側当接面である緩衝部材10の底面10cにおいても負荷応力を均一にでき、より確実に緩衝部材10の倒れや座屈等による変形を防ぐことができる。
【0024】
次に、本発明の他の実施の形態を図4を参照して説明する。図4に示すように、ダンパーブラケット42は、バックドア取り付け面46と、その取り付け面46が曲折されて形成されたダンパー取り付け面48とを有し、断面が略L字型の形状となっており、緩衝部材31の取り付け面46aはバックドア取り付け面46が延設された面であり、その面上には貫通孔80が設けられている。
【0025】
また緩衝部材31は、その上下端面からそれぞれ下方向、上方向に拡底した形状の円錐台31a、31bを有し、その中間には、貫通孔80の直径よりも小さい直径で緩衝部材31の取り付け面46aの板厚にほぼ等しい高さの円筒部31cを有し、それを介して各々の円錐台31a、31bが同心軸上につながれた形状となっている。そして、緩衝部材31は、円錐台31aが貫通孔80に挿嵌された後、円筒部31cが貫通孔80内に収まり、円錐台31a、31bがそれぞれ取り付け面46aを挟み込む形で取り付けられる。
【0026】
尚、ダンパーブラケットに緩衝部材を設け一体構造にする方法は他にも考えられ、緩衝部材の内側にネジ山を切った金属などを埋め込み、取り付け面を挟んで反対側から貫通孔を経てボルト等で締め付ける方法でも、さらに、そのボルトをブラケット本体に一体成形するという方法でも良い。
【0027】
さらに、本実施の形態の車両用扉開閉構造は、バックドアに限られず、自動車においては、フロントフード、フロントドア、リアドア等の開閉扉に用いることができ、また、ダンパステーを開閉扉側から差出してダンパーブラケットを車体側に設けることも可能である。
【0028】
以上に説明したように、本実施の形態の車両用扉開閉構造では、ダンパーブラケット2と緩衝部材10とを一体にすることで、部品点数を削減できるとともに、後部開口フランジ15とバックドア見切り13間の距離が縮められ、それにより後部開口が大きくとれ、そしてダンパーブラケット2近傍の空間を有効に利用できる。また、ダンパーブラケット2本体の、緩衝部材10に貫入された芯部の基部8a、先端部8bは、緩衝部材10と車体25の当接面を支持、補強し、緩衝部材10の倒れや変形を防ぎ、逆に緩衝部材10はその芯部の基部8a、先端部8bを包み込むので、ドライバー保護の観点からも有効なものとなる。
【0029】
そしてまた緩衝部材10は、バックドア1側で、そのインナパネル1aに当接するように成型されており、車体側の当接面11だけを支持するのではなく、バックドアのインナパネル1aを面全体で支持するので、それによりバックドア1開閉時の安定性が向上されるとともに、自らの強度を上げるという効果も併せ持つ。
【0030】
【発明の効果】
以上説明したように、請求項1に係るこの構成の車両用扉開閉構造では、ダンパステーは、車体と該車体に開閉可能に設けられた扉との間に設けられ、車両用扉開閉構造において、ダンパステーの各端部は、その端部に回動可能に結合されたブラケットを介して車体または扉に取り付けられ、緩衝部材は、ダンパステーの各端部のブラケットの内少なくとも一方のブラケットに設けられ、扉を閉じたときに車体または扉に当接して衝撃を吸収することができる。従って、開閉扉を設けた車体開口の幅を広くでき、また設計の自由度を増大できるという効果がある。
【0031】
また、請求項に係る発明の車両用扉開閉構造では、ブラケットは固定部と芯部とを備え、固定部は、車体または扉に固定され、芯部は、緩衝部材の内部に貫入されるので、緩衝部材の倒れや座屈による変形などを防止することができ、強く開閉扉が閉められても見切り干渉を防ぐことができる。
【0032】
さらに、請求項に係る発明の車両用扉開閉構造では、請求項に記載の車両用扉開閉構造の効果に加えて、前記芯部は、基部と先端部とを備え、基部は、衝撃部材が車体または扉に当接する方向に延出し、先端部は、基部の先端より車体または扉に当接する衝撃部材の当接面に対し平行に延出するので、より確実に緩衝部材の倒れや変形などを防止することができ、また強く開閉扉が閉められても、より確実に見切り干渉を防止することができる。
【0033】
また、請求項に係る発明の車両用扉開閉構造では、請求項又は請求項に記載の車両用扉開閉構造の効果に加えて、緩衝部材は、その当接面とは反対側に端面を有し、端面は、ブラケットの固定部、車体または扉に当接している。従って、緩衝部材は、開閉板のインナパネルと車体のアウタパネルの両方を面全体で支持し開閉扉の開閉時の安定性を向上させることができ、また自ら強度を上げることもできる。

[0027]
Furthermore, the vehicle door opening / closing structure of the present embodiment is not limited to a back door, and can be used for an opening / closing door such as a front hood, a front door, and a rear door in an automobile, and a damper stay is sent out from the opening / closing door side. It is also possible to provide a damper bracket on the vehicle body side.
[0028]
As described above, in the vehicle door opening / closing structure of the present embodiment, the number of parts can be reduced by integrating the damper bracket 2 and the buffer member 10, and the rear opening flange 15 and the back door parting 13 can be reduced. The distance between them is shortened, so that the rear opening can be made larger and the space near the damper bracket 2 can be used effectively. Further, the base portion 8a and the tip end portion 8b of the core portion of the damper bracket 2 main body that are inserted into the buffer member 10 support and reinforce the contact surfaces of the buffer member 10 and the vehicle body 25, so that the buffer member 10 is not tilted or deformed. On the contrary, since the buffer member 10 wraps around the base 8a and the tip 8b of the core, it is also effective from the viewpoint of driver protection.
[0029]
The buffer member 10 is molded on the back door 1 side so as to abut against the inner panel 1a, and does not support only the abutment surface 11 on the vehicle body side, but covers the inner panel 1a of the back door. Since it is supported as a whole, it improves the stability when the back door 1 is opened and closed, and also has the effect of increasing its own strength.
[0030]
