Description
本発明は、車両の前部車体構造に関する。
The present invention relates to a front body structure of a vehicle.
実開平２－１４３３６８号公報には、カウルトップアウタパネルとカウルトップインナパネルとダッシュパネルの３部材を閉断面形状に結合したカウルが開示されている。
Japanese Utility Model Laid-Open No. 2-143368 discloses a cowl in which three members of a cowl top outer panel, a cowl top inner panel, and a dash panel are combined in a closed cross-sectional shape.
しかし、上記構造は、カウルを３部材で構成しているため、コストや重量の増大を招く。また、３つの部材を三次元的に組み合わせるため、各部材の製造誤差を吸収して組み合わせることが難しく、各部材に対して高い寸法精度が要求される。従って、生産性の向上を図ることが難しい。
However, in the above structure, since the cowl is composed of three members, the cost and weight are increased. In addition, since the three members are combined three-dimensionally, it is difficult to absorb the manufacturing errors of the members and combine them, and high dimensional accuracy is required for each member. Therefore, it is difficult to improve productivity.
そこで、本発明は、生産性を向上させることが可能な車両の前部車体構造の提供を目的とする。
Therefore, an object of the present invention is to provide a vehicle front body structure capable of improving productivity.
上記目的を達成すべく、本発明の車両の前部車体構造は、フロアパネルとダッシュパネルとカウルパネルとを有する。ダッシュパネルは、車幅方向に沿って配置されて車室前方を区画し、フロアパネルから起立する。カウルパネルは、車幅方向に沿って配置され、ダッシュパネルの前面にそれぞれ溶着される上端部及び下端部を有し、これら上端部と下端部との間でダッシュパネルの前方に膨出してダッシュパネルとの間で閉断面形状の内部空間を形成し、上端部でフロントウインドウパネルの下縁部を支持する。
In order to achieve the above object, the front body structure of the vehicle of the present invention includes a floor panel, a dash panel, and a cowl panel. The dash panel is arranged along the vehicle width direction, partitions the front of the passenger compartment, and stands up from the floor panel. The cowl panel is disposed along the vehicle width direction and has an upper end and a lower end that are respectively welded to the front surface of the dash panel. The cowl panel bulges forward in front of the dash panel between the upper end and the lower end. An internal space having a closed cross-sectional shape is formed with the panel, and the lower edge of the front window panel is supported at the upper end.
上記構成では、フロントウインドウパネルとエンジンフードとの間に配置する車体部材を、フロアパネルとダッシュパネルの２部材で構成しているので、コストや重量の低減を図ることができる。また、２つの部材の組み合わせであるため、各部材の製造誤差を吸収し易く、生産性が向上する。
In the above configuration, since the vehicle body member disposed between the front window panel and the engine hood is composed of two members, the floor panel and the dash panel, cost and weight can be reduced. Moreover, since it is a combination of two members, it is easy to absorb the manufacturing error of each member, and productivity improves.
また、カウルパネルとダッシュパネルとの間には、車幅方向に沿った閉断面が形成されるので、所望の車体剛性を確保することができる。
In addition, since a closed section along the vehicle width direction is formed between the cowl panel and the dash panel, desired vehicle body rigidity can be ensured.
また、前方のエンジンルームと後方の車室とを１つのダッシュパネルによって仕切っているので、複数の部材を接合して仕切った場合に必要となる接合部分が存在せず、エンジンルームと車室とを完全に遮断することが可能となる。従って、エンジン音、熱、排気、水、及び埃等のエンジンルームから車室への侵入を確実に抑制することができる。
Further, since the front engine compartment and the rear compartment are partitioned by a single dash panel, there are no joint portions required when a plurality of members are joined and partitioned, and the engine compartment and the compartment Can be completely blocked. Therefore, intrusion of engine sound, heat, exhaust, water, dust and the like from the engine room into the vehicle compartment can be reliably suppressed.
また、カウルパネルは、エンジンフードの後端縁との間で外気を流入させる外気流入口を区画するとともに、外気流入口の下方領域と内部空間とを連通する上流側通気孔を有してもよく、ダッシュパネルは、内部空間を後方へ開口する下流側通気孔を、上流側通気孔と対向する位置又は上流側通気孔よりも上方位置に有してもよい。
Further, the cowl panel may define an external airflow inlet for allowing outside air to flow between the rear end edge of the engine hood, and may have an upstream side air vent that communicates the lower area of the external airflow inlet with the internal space. The dash panel may have a downstream side air hole that opens the inner space rearward at a position facing the upstream side air hole or above the upstream side air hole.
上記構成では、外気流入口から取り入れられた外気は、上流側通気孔から下流側通気孔に向かってほぼ水平方向か或いは斜め上方に流れ、ダッシュパネルの後方の車室へ流入する。従って、雨等の水が下側通気孔から車室内へ侵入するのを抑制することができる。
In the above configuration, the outside air taken in from the outside air flow inlet flows substantially horizontally or obliquely upward from the upstream vent hole toward the downstream vent hole, and flows into the passenger compartment behind the dash panel. Therefore, water such as rain can be prevented from entering the vehicle interior from the lower vent.
本発明によれば、所望の剛性を確保しつつ、エンジン音、熱、排気、水、及び埃等の車室への侵入を抑制し、且つ生産性の向上を図ることができる。
According to the present invention, it is possible to suppress the intrusion of engine sound, heat, exhaust, water, dust and the like into the passenger compartment and improve productivity while ensuring desired rigidity.
