特開２００６−１６８６３１公報JP 2006-168631 A

図１０及び図１１において、エンジンフード１０２に開口部１０３を設けることで、エンジンフード１０２の開口部１０３の周辺の剛性が低下し、振動発生や浮き上がりなどの原因になる。   10 and 11, by providing the opening 103 in the engine hood 102, the rigidity of the periphery of the opening 103 of the engine hood 102 is reduced, which causes vibrations and lifting.

また、エンジンフードに設けられた開口部を覆う構造として、以下の図１２及び図１３に示すものが知られている。
図１２に示すように、エンジンフード１１０を構成するアウタパネル１１１及びインナパネル１１２にそれぞれ開口部１１３，１１４が開けられ、アウタパネル１１１の開口部１１３を覆うために、開口部１１３の周縁にカバー部材１１６の取付部１１７が複数のボルト１１８で取付けられる。
カバー部材１１６に通気穴１１９が設けられていると、この通気穴１１９を通じて外部から取付部１１７が見えるため、外観性が損なわれる。 Moreover, what is shown in the following FIG.12 and FIG.13 is known as a structure which covers the opening part provided in the engine hood.
As shown in FIG. 12, openings 113, 114 are opened in the outer panel 111 and the inner panel 112 constituting the engine hood 110, respectively, and a cover member 116 is provided around the periphery of the opening 113 to cover the opening 113 of the outer panel 111. Are attached with a plurality of bolts 118.
When the ventilation hole 119 is provided in the cover member 116, the attachment portion 117 can be seen from the outside through the ventilation hole 119, so that the appearance is impaired.

図１３に示すように、エンジンフード１２０を構成するアウタパネル１２１及びインナパネル１２２にそれぞれ開口部１２３，１２４が開けられ、アウタパネル１２１の開口部１２３を覆うために、開口部１２４の周縁にカバー部材１２６のフランジ部１２７が複数のボルト１２８及びナット１２９で取付けられる。   As shown in FIG. 13, openings 123 and 124 are opened in the outer panel 121 and the inner panel 122 constituting the engine hood 120, respectively, and a cover member 126 is provided around the periphery of the opening 124 to cover the opening 123 of the outer panel 121. The flange portion 127 is attached with a plurality of bolts 128 and nuts 129.

アウタパネル１２１は、その縁がインナパネル１２２の縁の表から裏に折り返すようにヘミング結合されるため、ヘミング結合時にアウタパネル１２１とインナパネル１２２とがずれることがある。このため、アウタパネル１２１の開口部１２３と、インナパネル１２２に取付けられたカバー部材１２６との間に出来る隙間Ｓ１を大きく確保して干渉を防がなければならない。   Since the outer panel 121 is hemmed so that the edge is folded back from the front of the edge of the inner panel 122, the outer panel 121 and the inner panel 122 may be displaced during hemming. For this reason, it is necessary to ensure a large gap S1 between the opening 123 of the outer panel 121 and the cover member 126 attached to the inner panel 122 to prevent interference.

本発明の目的は、フードの開口と、この開口を覆うカバー部材との隙間をより小さくするとともに、開口周辺の剛性を向上させることが可能な車体前部構造を提供することにある。   An object of the present invention is to provide a vehicle body front structure that can further reduce the gap between the opening of the hood and the cover member that covers the opening and improve the rigidity around the opening.

請求項１に係る発明は、車体前部の上方を開閉自在に覆うフードを構成するアウタパネルに通気のための外開口が開けられ、この外開口が通気可能なカバー部材で塞がれた車体前部構造において、アウタパネルの内側に取付けられたインナパネルが、外開口の内側に開けられた内開口を有し、アウタパネル、インナパネル間に設けられる補強板が、その周縁側がアウタパネルと接着固定され、内開口側がインナパネル及びカバー部材と共締めされ、フードの後部左右に、フードを車体側に設けられたヒンジに取付けるためのヒンジ側取付部が設けられ、これらのヒンジ側取付部の車幅方向内側に左右の外開口及び内開口が開けられ、補強板は、内開口を囲う開口補強部と、これら左右の開口補強部を連結するためにフードの後縁に平行に設けられた断面ハット状の連結部とから構成され、インナパネルの後部には、断面ハット状の後部凹部が車幅方向に渡って形成され、断面ハット状の連結部は、断面ハット状の後部凹部に沿った形状に形成され、最も低く設けられた底壁と、この底壁の前端から前方斜め上方に延びる前傾斜壁と、この前傾斜壁の前端から前方に延びる前フランジと、底壁の後端から後方斜め上方に延びる後傾斜壁と、この後傾斜壁の後端から後方に延びる後フランジとからなり、前フランジ及び後フランジがインナパネルに取付けられることにより、連結部とインナパネルとによって閉断面が構成されていることを特徴とする。 According to the first aspect of the present invention, an outer opening for venting is formed in an outer panel that constitutes a hood that covers an upper portion of the front of the vehicle body so as to be openable and closable, and the outer opening is closed by a cover member that allows ventilation. In the partial structure, the inner panel attached to the inner side of the outer panel has an inner opening that is opened to the inner side of the outer opening, and the reinforcing plate provided between the outer panel and the inner panel is bonded and fixed to the outer panel on the peripheral side. The inner opening side is fastened together with the inner panel and the cover member, and the left and right rear portions of the hood are provided with hinge-side attachment portions for attaching the hood to hinges provided on the vehicle body side, and the vehicle width of these hinge-side attachment portions The left and right outer and inner openings are opened on the inner side in the direction, and the reinforcing plate is provided parallel to the rear edge of the hood to connect the opening reinforcing part surrounding the inner opening and the left and right opening reinforcing parts. A cross-section hat-shaped connecting portion, a cross-section hat-shaped rear recess is formed in the vehicle width direction at the rear portion of the inner panel, and the cross-section hat-shaped connection portion is a cross-section hat-shaped rear recess. A bottom wall that is formed in a shape along the bottom, extends forward and obliquely upward from the front end of the bottom wall, a front flange that extends forward from the front end of the front inclined wall, and a bottom wall A rear inclined wall extending obliquely upward from the rear end and a rear flange extending rearward from the rear end of the rear inclined wall, and the front flange and the rear flange are attached to the inner panel, thereby connecting the connecting portion and the inner panel. A closed cross section is constituted by the above.

アウタパネル、インナパネル間が補強板で連結されるため、アウタパネルとインナパネルとをヘミング結合したときにアウタパネルとインナパネルとのずれが防止される。
従って、アウタパネルとインナパネルとの位置ばらつきが抑えられ、外開口の縁とカバー部材との隙間をより小さくすることが可能になる。また、補強板によって、内開口周辺の剛性が高まる。 Since the outer panel and the inner panel are connected by the reinforcing plate, the outer panel and the inner panel are prevented from being displaced when the outer panel and the inner panel are hemmed.
Therefore, the positional variation between the outer panel and the inner panel is suppressed, and the gap between the edge of the outer opening and the cover member can be further reduced. Further, the rigidity around the inner opening is increased by the reinforcing plate.

左右の開口補強部を連結部で連結することで、フードの左右のヒンジ側取付部間の剛性が高まる。更に、連結部を断面ハット状にしたことで、連結部の剛性が高まり、左右のヒンジ側取付部間の剛性がより一層向上する。この結果、フードを開閉する際の操作感や開閉音の音質などが向上する。   The rigidity between the left and right hinge side mounting portions of the hood is increased by connecting the left and right opening reinforcing portions with the connecting portion. Furthermore, since the connecting portion has a hat shape in cross section, the rigidity of the connecting portion is increased, and the rigidity between the left and right hinge side mounting portions is further improved. As a result, the operational feeling when opening and closing the hood, the sound quality of the opening and closing sound, and the like are improved.

請求項１に係る発明では、アウタパネルの内側に取付けられたインナパネルが、外開口の内側に開けられた内開口を有し、アウタパネル、インナパネル間に設けられる補強板は、その周縁側がアウタパネルと接着固定され、内開口側がインナパネル及びカバー部材と共締めされているので、外開口とカバー部材との隙間をより小さくすることができ、外観性を向上させることができる。また、インナパネルの内開口周辺の剛性を高めることができ、フードの剛性を確保することができる。   In the invention according to claim 1, the inner panel attached to the inner side of the outer panel has an inner opening opened inside the outer opening, and the reinforcing plate provided between the outer panel and the inner panel has a peripheral side on the outer panel. Since the inner opening side is fastened together with the inner panel and the cover member, the gap between the outer opening and the cover member can be further reduced, and the appearance can be improved. Further, the rigidity around the inner opening of the inner panel can be increased, and the rigidity of the hood can be ensured.

加えて、請求項１に係る発明では、フードの後部左右に、フードを車体側に設けられたヒンジに取付けるためのヒンジ側取付部が設けられ、これらのヒンジ側取付部の車幅方向内側に左右の外開口及び内開口が開けられ、補強板が、内開口を囲う開口補強部と、これら左右の開口補強部を連結するためにフードの後縁に平行に設けられた断面ハット状の連結部とから構成されるので、断面ハット状の連結部によってフードの左右のヒンジ側取付部間の剛性をより一層高めることができ、フード開閉時のフィーリングを向上させることができる。 In addition, in the invention according to claim 1 , hinge-side attachment portions for attaching the hood to hinges provided on the vehicle body side are provided on the left and right of the rear portion of the hood, and these hinge-side attachment portions are arranged on the inner side in the vehicle width direction. The left and right outer openings and inner openings are opened, and the reinforcing plate is connected to the opening reinforcing portion surrounding the inner opening, and a cross-sectional hat-like connection provided in parallel to the rear edge of the hood to connect the left and right opening reinforcing portions. Therefore, the rigidity between the left and right hinge side attachment portions of the hood can be further increased by the connecting portion having a hat-shaped cross section, and the feeling at the time of opening and closing the hood can be improved.
