Description
本発明は車両用ドア、特にドア前面部にドアヒンジを取付けてドア前面部を車体へヒンジ結合する車両用ドアの補強構造に関する。 The present invention relates to a vehicle door, and more particularly to a vehicle door reinforcement structure in which a door hinge is attached to a front portion of a door and the door front portion is hinged to a vehicle body.
一般に、車両用ドアはアウタパネルとインナパネルとで中空構造をなすドア本体を備え、ドア本体のドア前面部にドアヒンジが取付られ、該ドアヒンジを介して車体へヒンジ結合される。このため、ドア前面部はドアヒンジ取付部の剛性を強化することが行われている。 Generally, a vehicle door includes a door main body having a hollow structure with an outer panel and an inner panel, and a door hinge is attached to the front surface of the door main body, and is hinged to the vehicle body via the door hinge. For this reason, strengthening the rigidity of a door hinge attachment part is performed for the door front part.
従来のドアヒンジ取付部の補強構造として、ドア前面部の背面に沿うように補強部材を重ね合わせて設けたり、ドア前面部の背面から若干離間したドア本体内の奥まった位置に補強部材を設け、ドア前面部に形成した開口部を貫通してドアヒンジを上記補強部材に取付けることが行われている（例えば、特許文献１，２参照。）。
またドア本体上縁のベルトラインでは、アウタパネルの上縁とインナパネルの上縁とが分離され、両者間に昇降式のドア窓ガラスを挿通する開口が形成されているので強度が充分でないことから、アウタパネルの内面上縁およびインナパネルの内面上縁に沿ってそれぞれ前後方向に延びる金属板からなるドアアウタリィンフォースメントとドアインナリィンフォースメントとを設け、車両の前面衝突時等の衝突荷重に対しドアの前後方向の剛性を強化することが行われている。 Also, in the belt line on the upper edge of the door body, the upper edge of the outer panel and the upper edge of the inner panel are separated, and an opening for inserting the elevating door window glass is formed between them, so the strength is not sufficient A door outer reinforcement and a door inner reinforcement made of a metal plate extending in the front-rear direction along the inner surface upper edge of the outer panel and the inner surface upper edge of the inner panel are provided, respectively. On the other hand, the rigidity in the front-rear direction of the door is strengthened.
ところで、車両用ドアはドア窓ガラスやこれを昇降せしめるレギュレータ装置、上記各リィンフォースメント等が内装され、ドア全体の重量が増し、特に、スポーツタイプの２ドアクーペやコンバーチブル等の乗用車では、ドア全長が長く大型であるために重量が重くなる。重量が重いと車体とのヒンジ結合部の周辺に負担がかかるが、ドア前面部は上記補強部材によりドアヒンジ取付部の剛性が強化されるのでそれ自体の変形は防止され得る。しかしながら、前端が支持されたドアには後端側に荷重が集中し、加えてドア開放状態で乗員が上からドアにもたれかかったりしてそれが繰り返されると、アウタパネルおよびインナパネルが歪んでドア下がり変形が生じ、車体へのドア建付け性が悪くなる。 By the way, the door for a vehicle is equipped with a door window glass, a regulator device for raising and lowering the door, the above reinforcements, etc., and the overall weight of the door is increased. Because of the long and large size, the weight becomes heavy. If the weight is heavy, a load is applied to the periphery of the hinge coupling portion with the vehicle body. However, since the rigidity of the door hinge mounting portion is reinforced by the reinforcing member, the door front portion can be prevented from deforming itself. However, if the load is concentrated on the rear end side of the door where the front end is supported, and the occupant leans against the door from the top with the door open, the outer panel and the inner panel are distorted and the door is distorted. Lowering deformation occurs, and the door mounting property to the vehicle body becomes worse.
そこで本発明は、新たに補強部材を追加することなく、ドアの下がり変形を防止して車体へのドアの建付け性を向上し、かつ車両の前面衝突時の衝突荷重に対する剛性の高い車両用ドアを提供することを課題としてなされたものである。 Therefore, the present invention is for a vehicle having high rigidity against a collision load at the time of a frontal collision of the vehicle, without adding a new reinforcing member, preventing the door from being lowered and improving the door's mounting property. Providing a door is an issue.

In the present embodiment, the front extension portion 61 of the reinforcing member 6 that reinforces the door front face portion 21 and the front end 31 of the door outer reinforcement 3 are combined, and the rear extension portion 62 of the reinforcing member 6 and the door inner are connected. A front end 41 of the reinforcement 4 is connected.
本実施形態によれば、補強部材６とドアアウタリィンフォースメント３およびドアインナリィンフォースメント４とを連結したから、補強部材６で強化されたドア前面部２１と両ドアリィンフォースメント３，４とが一体にドア全体の重量を支え、高い支持力が発揮されるのでドアの下がり変形を確実に防止する。また車両の前面衝突時には、補強部材６と両ドアリィンフォースメント３，４が一体に衝撃荷重を受けるので衝突荷重に対するドア剛性をより強化することができる。尚、本発明はドアフレームの設定のないドア限らず、セダン等の乗用車に用いるドアフレームを備えたドアに適用してもよい。 According to the present embodiment, since the reinforcing member 6 and the door outer reinforcement 3 and the door inner reinforcement 4 are connected, the door front portion 21 reinforced by the reinforcing member 6 and both door reinforcements 3 and 4 are connected. Supports the weight of the door as a whole, and high support force is exerted to prevent the door from falling down. Further, at the time of a frontal collision of the vehicle, the reinforcing member 6 and the door reinforcements 3 and 4 are integrally subjected to an impact load, so that the door rigidity against the collision load can be further enhanced. The present invention is not limited to a door without a door frame, and may be applied to a door provided with a door frame used for a passenger car such as a sedan.
