Description

本発明は、車両のフード構造に関し、さらに詳しくは、エンジンから伝わる振動を効率的に抑制できる剛性を有すると共に、車両が障害物に衝突したときに、該障害物から受ける衝突エネルギーを効率的に吸収することができる車両のフード構造に関する。   The present invention relates to a hood structure of a vehicle, and more specifically, has rigidity capable of efficiently suppressing vibration transmitted from an engine, and efficiently receives collision energy received from the obstacle when the vehicle collides with the obstacle. The present invention relates to a vehicle hood structure capable of absorbing.

車両前部にエンジンルームが設けられている車両においては、このエンジンルームの開口部を塞ぐフードが開閉自在に配設されている。   In a vehicle in which an engine room is provided in the front part of the vehicle, a hood that closes the opening of the engine room is disposed so as to be openable and closable.

このフードは、複数のリブからなる骨格部が形成されたインナーパネルの周縁部を、アウターパネルの外周フランジをヘミング加工して一体化することにより構成されている（例えば、特許文献１参照）。
特開２０００−１１８２公報 This hood is configured by integrating a peripheral portion of an inner panel in which a skeleton portion including a plurality of ribs is formed by hemming an outer peripheral flange of the outer panel (see, for example, Patent Document 1).
JP 2000-1182 A

しかしながら、前記従来例では、フード全体の剛性を低くし過ぎると、エンジンから伝わる振動によってフード自体が振動し、さらにステアリングの振動等を引き起こすおそれがあった。その一方、フードの剛性を高くし過ぎると、車両が障害物に衝突したときに、障害物に対して高い反力を与えるおそれがあった。   However, in the conventional example, if the rigidity of the entire hood is too low, the hood itself may vibrate due to vibrations transmitted from the engine, which may cause vibration of the steering. On the other hand, if the rigidity of the hood is too high, there is a risk that a high reaction force is applied to the obstacle when the vehicle collides with the obstacle.

そこで、本発明は、フードの振動を抑制すると共に、車両衝突時における障害物に対する反力を小さくする車両のフード構造を提供することを目的としている。   Therefore, an object of the present invention is to provide a vehicle hood structure that suppresses vibration of the hood and reduces reaction force against an obstacle at the time of a vehicle collision.

前記目的を達成するために、本発明は、車両上方側に設けられるアウターパネルと、該アウターパネルの車両下方側に張設されると共に、下方に膨出する複数のリブからなる骨格部を有するインナーパネルとを備え、前記骨格部を、車両前後方向に延びる主骨部と、車幅方向に延びて前記主骨部同士を連結する小骨部とから構成することにより、これらのインナーパネルの骨格部とアウターパネルとによって中空断面を形成する車両のフード構造において、前記主骨部から小骨部に沿って間隔をおいた所定部位に対応するアウターパネルの下面側に、補強手段をアウターパネルに近接させて配置させている。   In order to achieve the above object, the present invention has an outer panel provided on the upper side of a vehicle, and a skeleton portion that is provided on the vehicle lower side of the outer panel and includes a plurality of ribs that bulge downward. An inner panel, and the skeleton portion includes a main bone portion that extends in the vehicle front-rear direction and a small bone portion that extends in the vehicle width direction and connects the main bone portions to each other. In a vehicle hood structure in which a hollow cross-section is formed by a portion and an outer panel, a reinforcing means is adjacent to the outer panel on the lower surface side of the outer panel corresponding to a predetermined portion spaced from the main bone portion along the small bone portion. And let them be placed.

本発明によれば、主骨部から車幅方向に間隔をおいた小骨部の所定部位に対応するアウターパネルの下面側に、補強手段をアウターパネルに近接させて配置しているため、この補強手段によってアウターパネルの剛性が向上して、補強手段近傍のフードの剛性が向上し、フードの振動を抑制することができる。   According to the present invention, the reinforcing means is disposed close to the outer panel on the lower surface side of the outer panel corresponding to the predetermined portion of the small bone part spaced from the main bone part in the vehicle width direction. The rigidity of the outer panel is improved by the means, the rigidity of the hood near the reinforcing means is improved, and the vibration of the hood can be suppressed.

また、インナーパネルの骨格部とアウターパネルとによって中空断面を形成しているため、車両衝突時には、この中空断面によって衝突エネルギーを吸収して、障害物に対する反力を小さくすることができる。   Further, since the hollow section is formed by the skeleton part of the inner panel and the outer panel, the collision energy can be absorbed by the hollow section at the time of a vehicle collision, and the reaction force against the obstacle can be reduced.

このように、本発明によれば、フードの振動を抑制すると共に、車両衝突時における障害物に対する反力を小さくすることができる。   Thus, according to the present invention, the vibration of the hood can be suppressed and the reaction force against the obstacle at the time of the vehicle collision can be reduced.

以下、本発明の実施形態を図面と共に詳述する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[第１の実施形態]
図１は本発明の第１実施形態によるフード構造を採用した車両の前部を示す斜視図である。 [First embodiment]
FIG. 1 is a perspective view showing a front portion of a vehicle employing a hood structure according to a first embodiment of the present invention.

車両１の前部には、エンジンルーム３が配設されており、該エンジンルーム３の開口部は、開閉自在のフード５によって閉塞される。即ち、フード５の後端部の左右両側は、ヒンジ装置６を介して車体側のフードリッジに開閉自在に支持されている。   An engine room 3 is disposed at the front of the vehicle 1, and an opening of the engine room 3 is closed by a hood 5 that can be freely opened and closed. That is, the left and right sides of the rear end portion of the hood 5 are supported by the hood ridge on the vehicle body side via the hinge device 6 so as to be freely opened and closed.

図２は図１のフードを分解した斜視図である。   FIG. 2 is an exploded perspective view of the hood of FIG.

本発明の実施形態によるフード５は、上側に配置されたアウターパネル７と、下側に配置されたインナーパネル９とから構成されており、該インナーパネル９の周縁部１１を、アウターパネル７の周縁フランジ１３でヘミング加工することによって、アウターパネル７とインナーパネル９とが一体に形成される。   The hood 5 according to the embodiment of the present invention includes an outer panel 7 disposed on the upper side and an inner panel 9 disposed on the lower side, and the peripheral portion 11 of the inner panel 9 is connected to the outer panel 7. The outer panel 7 and the inner panel 9 are integrally formed by hemming with the peripheral flange 13.

また、インナーパネル９には、車両前後方向及び車幅方向に沿って延びる複数のリブが互いに交差しており、これらのリブによって骨格部１５を構成している。このリブは、インナーパネル９の面を下方に膨出させたものであり、リブとアウターパネル７とによって中空断面（図４参照）１７を形成している。   The inner panel 9 includes a plurality of ribs extending in the vehicle front-rear direction and the vehicle width direction, and the skeleton portion 15 is configured by these ribs. The rib is formed by bulging the surface of the inner panel 9 downward, and the rib and the outer panel 7 form a hollow cross section (see FIG. 4) 17.

さらに、前記骨格部１５は、車両前後方向に延びる主骨部１９と、車幅方向に延びて前記主骨部同士を連結する小骨部とから構成されている。この図２においては、各リブは車幅方向中央側の主骨部１９を境として、左右両側に対称に配置されている。   Further, the skeleton part 15 includes a main bone part 19 extending in the vehicle front-rear direction and a small bone part extending in the vehicle width direction and connecting the main bone parts to each other. In FIG. 2, the ribs are arranged symmetrically on both the left and right sides with the main bone portion 19 on the center side in the vehicle width direction as a boundary.

具体的には、主骨部１９は、車幅方向中央に配置されて車両前後方向に沿って延びる第１主骨部２１と、該第１主骨部２１の左右両側に隣接して形成された第２主骨部２３と、該第２主骨部２３の左右両側で、かつ、インナーパネル９の左右側端部に配置された第３主骨部２５とからなる。また、第２主骨部２３の前端２３ａは第１主骨部２１の前端２１ａと同一部位に配置され、車両後方に向かうにつれて徐々に左右両側に広がるように斜めに延びている。また、小骨部２７は、第１主骨部２１と第２主骨部２３とを連結する第１小骨部２９及び第２小骨部３１、第２主骨部２３と第３主骨部２５とを連結する第３小骨部３３及び第４小骨部３５から構成されている。   Specifically, the main bone portion 19 is formed adjacent to both the left and right sides of the first main bone portion 21 and the first main bone portion 21 that is disposed at the center in the vehicle width direction and extends along the vehicle longitudinal direction. The second main bone portion 23 and the third main bone portion 25 disposed on the left and right sides of the second main bone portion 23 and at the left and right end portions of the inner panel 9. Further, the front end 23a of the second main bone part 23 is disposed at the same site as the front end 21a of the first main bone part 21, and extends obliquely so as to gradually spread to the left and right sides as it goes rearward of the vehicle. Further, the small bone portion 27 includes a first small bone portion 29 and a second small bone portion 31 that connect the first main bone portion 21 and the second main bone portion 23, and the second main bone portion 23 and the third main bone portion 25. It is comprised from the 3rd small bone part 33 and the 4th small bone part 35 which connect.

なお、図２に示すように、インナーパネル９の主骨部１９には、車幅方向に沿って折れ促進ビード３７が一直線状に形成されている。この折れ促進ビード３７は、主骨部１９の底面を車両上方に向けて凹ませた脆弱部である。従って、車両１が前面衝突を起こした場合には、フード５に対して車両前側から衝突荷重が入力されるが、前記折れ促進ビード３７を起点としてフード５は上方に折れ曲がり、衝突エネルギーを効率的に吸収する。   As shown in FIG. 2, the main frame 19 of the inner panel 9 is formed with a fold-promoting bead 37 in a straight line along the vehicle width direction. This fold-promoting bead 37 is a fragile portion in which the bottom surface of the main bone portion 19 is recessed upward. Therefore, when the vehicle 1 has a frontal collision, a collision load is input to the hood 5 from the front side of the vehicle, but the hood 5 bends upward from the fold-promoting bead 37, and the collision energy is efficiently To absorb.

図３は図１の要部を拡大した斜視図であり、フードを上下逆に配置した状態を示している。即ち、図３の上側にはインナーパネル９が配置され、下側にはアウターパネル７が配置されている。また、図４は図３のＡ−Ａ線による断面図である。   FIG. 3 is an enlarged perspective view of the main part of FIG. 1 and shows a state in which the hood is arranged upside down.
