Description
本開示は、車両用フード構造に関する。
This disclosure relates to a vehicle hood structure.
車両のフロントフード（ボンネット）のストライカを車体側のロック機構に嵌合させたり、嵌合を解除したりする開閉操作時に、ストライカを介してフロントフードに上下方向に荷重が作用する。このような開閉操作時に作用する荷重に対してフロントフードにおけるストライカ近傍の部分の強度を高めるために種々の補強構造が設けられている。
When the striker of the front hood (bonnet) of the vehicle is fitted to the lock mechanism on the vehicle body side or released from the fitting, a load acts on the front hood in the vertical direction via the striker. Various reinforcing structures are provided in order to increase the strength of the portion of the front hood near the striker against the load acting during such an opening / closing operation.
例えば、特許文献１には、ボンネットインナパネルの前部中央にストライカが配置されると共に、ストライカが配置された位置に対応してボンネットインナパネルと共に閉断面を構成する補強部材が配置される。この補強部材には、車体前後方向に対して傾斜する複数のビードが一体に形成される構造が示されている。
For example, in Patent Document 1, a striker is arranged in the center of the front portion of the bonnet inner panel, and a reinforcing member constituting a closed cross section is arranged together with the bonnet inner panel corresponding to the position where the striker is arranged. The reinforcing member has a structure in which a plurality of beads inclined with respect to the front-rear direction of the vehicle body are integrally formed.
しかしながら、上述のように特許文献１に示されるビードは、フードインナパネルと共に閉断面を構成する補強部材に形成される構造であり、フードインナパネルとは別の部材にビードが形成される。フードインナパネル自体に、しかも、ストライカの両側にビードを形成する構造ではない。また、ビードの内部において両側壁を繋ぐようにさらにビードを形成してフードインナパネルの高剛性化を図ることは示されていない。従って、簡単な構造でフードインナパネルのストライカ周辺の高剛性化をさらに改善することが望まれる。
However, as described above, the bead shown in Patent Document 1 has a structure formed on a reinforcing member forming a closed cross section together with the hood inner panel, and the bead is formed on a member different from the hood inner panel. It is not a structure that forms beads on both sides of the striker on the hood inner panel itself. Further, it has not been shown that a bead is further formed inside the bead so as to connect both side walls to increase the rigidity of the hood inner panel. Therefore, it is desired to further improve the rigidity around the striker of the hood inner panel with a simple structure.
そこで、上記課題に鑑み、本発明の少なくとも一つの実施形態は、フロントフードの開閉時に、ストライカを介して作用する荷重に対してフロントフードにおけるストライカ近傍の部分の強度向上を簡単な構造で達成できる車両用フード構造を提供することを目的とする。
Therefore, in view of the above problems, at least one embodiment of the present invention can achieve an improvement in the strength of a portion of the front hood in the vicinity of the striker with a simple structure against a load acting via the striker when the front hood is opened and closed. It is intended to provide a vehicle hood structure.
（１）前述した目的を達成するために発明されたものであり、本開示の少なくとも一つの実施形態は、車両用のフロントフードの外面を構成するアウタパネルと、前記アウタパネルに対向配置され、前記フロントフードの内面を構成するインナパネルと、前記インナパネルに設けられ、前記フロントフードの前端部を車体にロックするためのストライカと、を備える車両用フード構造であって、前記インナパネルのストライカ取付部の車両後方側に、車両左右方向に延在し、前記インナパネルの面を前記アウタパネル側に階段状に形成される段差部が設けられ、前記インナパネルの前記ストライカ取付部の前記車両左右方向における両側に設けられ、前記段差部の稜線又は該稜線の延長線を横切るように車両前後方向に延在する縦ビードと、前記縦ビードの内部に設けられ、該縦ビードの両側壁を繋ぐように前記車両左右方向に延在する横ビードと、を備える。
(1) It was invented to achieve the above-mentioned object, and at least one embodiment of the present disclosure is an outer panel constituting an outer surface of a front hood for a vehicle and an outer panel arranged opposite to the outer panel and said to be the front. A vehicle hood structure including an inner panel constituting the inner surface of the hood and a striker provided on the inner panel for locking the front end portion of the front hood to the vehicle body, wherein the striker mounting portion of the inner panel is provided. A step portion is provided on the rear side of the vehicle so as to extend in the left-right direction of the vehicle and the surface of the inner panel is formed in a stepped shape on the outer panel side. A vertical bead provided on both sides and extending in the front-rear direction of the vehicle so as to cross the ridgeline of the step portion or an extension line of the ridgeline, and a vertical bead provided inside the vertical bead so as to connect both side walls of the vertical bead. A horizontal bead extending in the left-right direction of the vehicle is provided.
このような構成によれば、インナパネルのストライカ取付部の車両左右方向における両側に、車両前後方向に延在して縦ビードが形成され、しかも、縦ビードがインナパネルのストライカ取付部の車両後方側に車両左右方向に延在する階段状の段差部の稜線（実施形態の第２稜線Ｒ２）又は該稜線の延長線を横切るように形成されるので、車両用フードの開閉操作時に段差部の稜線部分に応力集中することによって生じる折れ変形を抑えることができる。
According to such a configuration, vertical beads are formed on both sides of the striker mounting portion of the inner panel in the vehicle left-right direction extending in the vehicle front-rear direction, and the vertical beads are formed behind the vehicle of the striker mounting portion of the inner panel. Since it is formed so as to cross the ridgeline of the stepped step portion (second ridgeline R2 of the embodiment) extending in the left-right direction of the vehicle on the side or the extension line of the ridgeline, the stepped portion is formed during the opening / closing operation of the vehicle hood. It is possible to suppress bending deformation caused by stress concentration on the ridgeline portion.
さらに、縦ビードの内部に該縦ビードの両側壁を繋ぐように車両左右方向に延在する横ビードが形成されるので、車両用フードの開閉操作時の荷重で縦ビードが車両左右方向に拡がり縦ビードの機能が低下することを防止できる。
Further, since a horizontal bead extending in the left-right direction of the vehicle is formed inside the vertical bead so as to connect both side walls of the vertical bead, the vertical bead expands in the left-right direction of the vehicle due to the load when opening and closing the vehicle hood. It is possible to prevent the function of the vertical bead from deteriorating.
従って、縦ビードと横ビードとによる簡単な構造によって、インナパネルのストライカ取付部周辺の高剛性化を実現できる。

(2) In some embodiments, in the configuration of (1), the horizontal bead is provided in a region other than the portion where the vertical bead crosses the ridgeline of the step portion or the extension line of the ridgeline.
このような構成によれば、縦ビードによる稜線部分における折れ変形の抑制効果が薄れることを解消できる。すなわち、段差部の稜線又は該稜線の延長線の部分に横ビードが設置されると、稜線が左右方向に延びる状態になり、稜線又は該稜線の延長線を縦ビードで分断することによって得られる稜線部分における折れ変形の抑制効果が薄れるので、これを解消することができる。
With such a configuration, it is possible to eliminate the diminished effect of suppressing bending deformation at the ridgeline portion due to the vertical bead. That is, when a horizontal bead is installed on the ridgeline of the step portion or the extension line of the ridgeline, the ridgeline extends in the left-right direction, and is obtained by dividing the ridgeline or the extension line of the ridgeline with a vertical bead. Since the effect of suppressing bending deformation at the ridgeline portion is diminished, this can be eliminated.
（３）幾つかの実施形態では、前記（１）または（２）の構成において、前記横ビードは、前記段差部の稜線又は該稜線の延長線の車両後方側に設けられる。
(3) In some embodiments, in the configuration of (1) or (2), the lateral bead is provided on the vehicle rear side of the ridgeline of the stepped portion or an extension line of the ridgeline.
このような構成によれば、横ビードによる縦ビードの拡がり防止効果を効果的に発揮できる。すなわち、横ビードが、縦ビードの後端部側に設けられるので縦ビードが開くことを効果的防止できる。さらに、横ビードによってストライカ取付部の後側における車両左右方向の剛性向上が図れる。
According to such a configuration, the effect of preventing the vertical bead from spreading due to the horizontal bead can be effectively exhibited. That is, since the horizontal bead is provided on the rear end side of the vertical bead, it is possible to effectively prevent the vertical bead from opening. Further, the lateral bead can improve the rigidity in the left-right direction of the vehicle on the rear side of the striker mounting portion.
（４）幾つかの実施形態では、前記（１）から（３）の構成において、前記縦ビードの前端は前記車両前後方向に閉塞されている。
(4) In some embodiments, in the configurations (1) to (3), the front end of the vertical bead is closed in the front-rear direction of the vehicle.
このような構成によれば、縦ビードの前端は、車両前後方向に閉塞されて蓋がされた状態であるので、フードインナパネルの前端部での車両左右方向の剛性向上が図れる。
According to such a configuration, the front end of the vertical bead is closed in the front-rear direction of the vehicle and covered, so that the rigidity of the front end of the hood inner panel in the left-right direction of the vehicle can be improved.
（５）幾つかの実施形態では、前記（４）の構成において、前記ストライカの中心位置は、前記インナパネルの平面視において前記横ビードの夫々の中心と、前記縦ビードの夫々の前端を閉塞する閉塞部の夫々の中心とを、繋いで形成される４角形の内側に存在する。
(5) In some embodiments, in the configuration of (4), the center position of the striker closes the center of each of the horizontal beads and the front end of each of the vertical beads in the plan view of the inner panel. It exists inside a quadrangle formed by connecting the centers of each of the closed portions.
このような構成によれば、ストライカ周辺の前後左右方向の高剛性化を実現し、車両用フードの開閉操作時に作用する上下荷重に対して、ストライカ取付部周辺における応力低減を図ることができる。
With such a configuration, it is possible to realize high rigidity in the front-rear and left-right directions around the striker, and to reduce the stress around the striker mounting portion against the vertical load acting during the opening / closing operation of the vehicle hood.

図１～６を参照して本発明の一実施形態を説明する。車両の前部のエンジンルームを開閉するフロントフード１は、フードアウタパネル３とフードインナパネル５とによって構成される（図３参照）。図１は、そのフードインナパネル５を、エンジンルーム側から見た下面斜視図を示す。
An embodiment of the present invention will be described with reference to FIGS. 1 to 6. The front hood 1 that opens and closes the engine room at the front of the vehicle is composed of a hood outer panel 3 and a hood inner panel 5 (see FIG. 3). FIG. 1 shows a bottom perspective view of the hood inner panel 5 as viewed from the engine room side.
図１に示すように、フードインナパネル５は、金属板（例えば、鋼板又はアルミニウム合金板）によって形成される。フードインナパネル５の外形形状は、平面視において車両左右方向に略左右対称形状を有し、また、車両前方部に向かって車両左右方方向が細くなる形状を有している。また、フードインナパネル５は、前方部に向かって下方向に階段状に突出する形状を有している。
As shown in FIG. 1, the hood inner panel 5 is formed of a metal plate (for example, a steel plate or an aluminum alloy plate). The outer shape of the hood inner panel 5 has a shape that is substantially symmetrical in the left-right direction of the vehicle in a plan view, and has a shape that narrows in the left-right direction of the vehicle toward the front portion of the vehicle. Further, the hood inner panel 5 has a shape that projects downward in a stepwise manner toward the front portion.
また、フードインナパネル５の左右の後部には、フロントフード１を車体側に開閉自在に連結される不図示のヒンジが設けられる。さらに、フードインナパネル５には、軽量化のために強度に影響しない箇所の重さを低減するために、または部品の取り付け作業等のために不図示の開口が設けられている。
Further, on the left and right rear parts of the hood inner panel 5, hinges (not shown) for connecting the front hood 1 to the vehicle body side so as to be openable and closable are provided. Further, the hood inner panel 5 is provided with an opening (not shown) in order to reduce the weight of a portion that does not affect the strength for weight reduction, or for mounting work of parts or the like.
ま、フードインナパネル５には、図１に示すように、フードインナパネル５の車両前部の車幅方向中央に、フロントフード１の下部側の車体に設けられるフードラッチ（不図示）に係合してフロントフード１をロックするストライカ９が設けられる。
Further, as shown in FIG. 1, the hood inner panel 5 is engaged with a hood latch (not shown) provided on the vehicle body on the lower side of the front hood 1 at the center of the front part of the hood inner panel 5 in the vehicle width direction. In addition, a striker 9 for locking the front hood 1 is provided.
ストライカ９は、略Ｕ字形状の金属製（例えば、鉄製）の部材からなり、両端部が金属製（例えば、鉄製）のストライカリンフォース１１（図３参照）に溶接固定され、ストライカリンフォース１１は、ストライカ取付面（ストライカ取付部）１３のフードアウタパネル３側の面にボルト又は溶接によって結合される。
The striker 9 is made of a substantially U-shaped metal (for example, iron) member, and both ends thereof are welded and fixed to the metal (for example, iron) striker reinforcement 11 (see FIG. 3). Is connected to the surface of the striker mounting surface (striker mounting portion) 13 on the hood outer panel 3 side by bolts or welding.
そして、ストライカ９は、フードインナパネル５のストライカ取付面１３に形成された貫通孔１４を貫通して車体側に突出するように取り付けられる。なお、ストライカ９の中心Ｐｓの位置は、車両の左右方向の中心位置と一致するように設けられる。
Then, the striker 9 is attached so as to penetrate the through hole 14 formed in the striker mounting surface 13 of the hood inner panel 5 and project toward the vehicle body side. The position of the center Ps of the striker 9 is provided so as to coincide with the center position in the left-right direction of the vehicle.
また、図１、２に示すように、フードインナパネル５の車両前方部１５は、下方向に階段状に隆起する形状を有し、車幅方向の中央部に中央隆起部１７と、車幅方向の左側部に左隆起部１９と、車幅方向の右側部に右隆起部２１とがそれぞれ形成されている。
Further, as shown in FIGS. 1 and 2, the vehicle front portion 15 of the hood inner panel 5 has a shape of a stepped downward ridge, and a central ridge portion 17 and a vehicle width are located in the central portion in the vehicle width direction. A left ridge 19 is formed on the left side in the direction, and a right ridge 21 is formed on the right side in the vehicle width direction.
さらに、中央隆起部１７、左隆起部１９、右隆起部２１のそれぞれは、中央前隆起部１７ａと中央後隆起部１７ｂ、左前隆起部１９ａと左後隆起部１９ｂ、右前隆起部２１ａと右後隆起部２１ｂを有し、前方側は後方側よりさらに下方向に隆起して階段状に形成されている。
Further, the central raised portion 17, the left raised portion 19, and the right raised portion 21, respectively, have the central anterior raised portion 17a and the central posterior raised portion 17b, the left front raised portion 19a and the left posterior raised portion 19b, and the right front raised portion 21a and the right rear. It has a raised portion 21b, and the front side is raised further downward from the rear side to form a stepped shape.
中央前隆起部１７ａは四角錐状に隆起し、この中央前隆起部１７ａの底面は、最も下方に突出した部分であり、ストライカ取付面１３を形成する。中央前隆起部１７ａと中央後隆起部１７ｂとの間には階段状の段差部２３が形成される。
The central anterior raised portion 17a is raised in a quadrangular pyramid shape, and the bottom surface of the central anterior raised portion 17a is the most downwardly protruding portion and forms the striker mounting surface 13. A stepped step portion 23 is formed between the central front raised portion 17a and the central rear raised portion 17b.
すなわち、ストライカ取付面１３の車両後方側に、車両左右方向に延在し、フードインナパネル５の面をフードアウタパネル３側に階段状に変位させる段差部２３が形成されている。そして、段差部２３の中央前隆起部１７ａ側には第１稜線Ｒ１が形成され、段差部２３の中央後隆起部１７ｂ側には第２稜線Ｒ２が形成される。
That is, a step portion 23 is formed on the rear side of the striker mounting surface 13 so as to extend in the left-right direction of the vehicle and to displace the surface of the hood inner panel 5 toward the hood outer panel 3 in a stepped manner. Then, the first ridge line R1 is formed on the central front raised portion 17a side of the step portion 23, and the second ridge line R2 is formed on the central rear raised portion 17b side of the step portion 23.
図３に、上述したストライカ取付面１３、段差部２３、中央前隆起部１７ａ、中央後隆起部１７ｂ、第１稜線Ｒ１、第２稜線Ｒ２の関係を示す。この図３は、ストライカ９の中心Ｐｓを通り車両前後方向である図２のＡ－Ａ線における断面概略図である。
FIG. 3 shows the relationship between the striker mounting surface 13, the stepped portion 23, the central front raised portion 17a, the central rear raised portion 17b, the first ridge line R1, and the second ridge line R2. FIG. 3 is a schematic cross-sectional view taken along the line AA of FIG. 2, which passes through the center Ps of the striker 9 and is in the front-rear direction of the vehicle.
ストライカリンフォース１１は、図３に示すように、中央前隆起部１７ａのフードアウタパネル３側の面において前側面、底面、後側面に渡って結合される板状部材である。第１稜線Ｒ１の部分は、ストライカリンフォース１１によって補強されるので、フロントフード１の開閉操作時に作用する応力集中によって折れ変形が問題となるのは、第２稜線Ｒ２の部分である。
As shown in FIG. 3, the striker reinforcement 11 is a plate-shaped member that is connected to the front side surface, the bottom surface, and the rear side surface on the surface of the central front ridge portion 17a on the hood outer panel 3 side. Since the portion of the first ridge line R1 is reinforced by the striker reinforcement 11, it is the portion of the second ridge line R2 that the bending deformation becomes a problem due to the stress concentration acting during the opening / closing operation of the front hood 1.
従って、この折れ変形に対応するために、図１、２に示すように、中央隆起部１７と左隆起部１９との間、及び中央隆起部１７と右隆起部２１との間には、車両前後方向に沿って延在する縦ビード２５、２７がそれぞれ形成されている。そして、この縦ビード２５、２７は、それぞれストライカ９の中心Ｐｓの左右の両側部分を通過し、さらに少なくとも第２稜線Ｒ２又は第２稜線Ｒ２の延長線を横切るように延びている。
Therefore, in order to cope with this bending deformation, as shown in FIGS. 1 and 2, there is a vehicle between the central raised portion 17 and the left raised portion 19 and between the central raised portion 17 and the right raised portion 21. Vertical beads 25 and 27 extending along the front-rear direction are formed, respectively. The vertical beads 25 and 27 pass through the left and right side portions of the center Ps of the striker 9, respectively, and further extend so as to cross at least the second ridge line R2 or the extension line of the second ridge line R2.
左縦ビード２５の車両前後方向の断面形状は、図２のＢ－Ｂ線における断面概略図を示す図４のように、左前隆起部１９ａの底面１９ａｓ及び左後隆起部１９ｂの底面１９ｂｓよりフードアウタパネル３側に突出した形状である。
The cross-sectional shape of the left vertical bead 25 in the vehicle front-rear direction is a hood from the bottom surface 19as of the left front raised portion 19a and the bottom surface 19bs of the left rear raised portion 19b, as shown in FIG. It has a shape protruding toward the outer panel 3.
また、右縦ビード２７の車両前後方向の断面形状は、図２のＣ－Ｃ線における断面概略図を示す図５のように、右前隆起部２１ａの底面２１ａｓ及び右後隆起部２１ｂの底面２１ｂｓよりフードアウタパネル３側に突出した形状である。
Further, the cross-sectional shape of the right vertical bead 27 in the vehicle front-rear direction is as shown in FIG. 5 showing a schematic cross-sectional view taken along the line CC of FIG. It has a shape that protrudes toward the hood outer panel 3 side.
また、左縦ビード２５及び右縦ビード２７の車両左右方向の断面形状は、図６に示すように、フードアウタパネル３側に突出した矩形断面形状である。図６は、図１の下面斜視図においてストライカ周辺部分の拡大図に断面の概略形状を重ねて表示した斜視図である。なお、断面形状については、矩形断面形状に限るものではなく、円弧形状や三角形状等であってもよい。
Further, the cross-sectional shape of the left vertical bead 25 and the right vertical bead 27 in the vehicle left-right direction is a rectangular cross-sectional shape protruding toward the hood outer panel 3 as shown in FIG. FIG. 6 is a perspective view showing a schematic shape of a cross section superimposed on an enlarged view of a portion around the striker in the bottom perspective view of FIG. The cross-sectional shape is not limited to the rectangular cross-sectional shape, and may be an arc shape, a triangular shape, or the like.
このように、フードインナパネル５のストライカ９の左右両側に、車両前後方向に延在して縦ビード２５、２７が形成され、しかも、縦ビード２５、２７が、フードインナパネル５のストライカ９の取付部の車両後方側に車両左右方向に延在する階段状の段差部２３の第２稜線Ｒ２又は第２稜線Ｒ２の延長線を横切るように形成されるので、フロントフード１の開閉操作時に段差部２３の第２稜線Ｒ２の部分に応力集中することによって生じる折れ変形を抑えることができる。
In this way, vertical beads 25 and 27 are formed on the left and right sides of the striker 9 of the hood inner panel 5 extending in the front-rear direction of the vehicle, and the vertical beads 25 and 27 are the strikers 9 of the hood inner panel 5. Since it is formed so as to cross the second ridge line R2 or the extension line of the second ridge line R2 of the stepped step portion 23 extending in the left-right direction of the vehicle on the vehicle rear side of the mounting portion, the step is formed during the opening / closing operation of the front hood 1. It is possible to suppress bending deformation caused by stress concentration on the portion of the second ridge line R2 of the portion 23.
また、縦ビード２５、２７のそれぞれの内部には、縦ビード２５、２７における両側壁を繋ぐように車両左右方向に延在する横ビード２９、３１が形成されている。この横ビード２９、３１を形成することによって、車両左右方向の剛性向上が図れるとともに、縦ビード２５、２７がフロントフード１の開閉操作時に作用する荷重によってそれぞれの縦ビード２５、２７における両側壁が車両左右方向に拡がり、縦ビード２５、２７によって発揮される車両前後方向の補強機能が低下することを防止できる。
Further, inside each of the vertical beads 25 and 27, horizontal beads 29 and 31 extending in the left-right direction of the vehicle are formed so as to connect both side walls of the vertical beads 25 and 27. By forming the horizontal beads 29 and 31, the rigidity in the left-right direction of the vehicle can be improved, and the loads acting on the vertical beads 25 and 27 when the front hood 1 is opened and closed causes both side walls of the vertical beads 25 and 27 to be formed. It spreads in the left-right direction of the vehicle and can prevent the vertical bead 25, 27 from deteriorating the reinforcing function in the front-rear direction of the vehicle.
従って、縦ビード２５、２７と横ビード２９、３１との簡単な構造によって、フードインナパネル５のストライカ９の取付部の周辺の高剛性化を実現できる。
Therefore, the simple structure of the vertical beads 25 and 27 and the horizontal beads 29 and 31 makes it possible to realize high rigidity around the mounting portion of the striker 9 of the hood inner panel 5.
さらに、左縦ビード２５及び右縦ビード２７は、車両前後方向に略同一の長さ、及び断面形状においても略同一の形状を有して、図１、２に示すように、左縦ビード２５及び右縦ビード２７の前端部分は車両前後方向において閉塞されている。
Further, the left vertical bead 25 and the right vertical bead 27 have substantially the same length in the vehicle front-rear direction and substantially the same cross-sectional shape, and as shown in FIGS. 1 and 2, the left vertical bead 25 The front end portion of the right vertical bead 27 is closed in the front-rear direction of the vehicle.
すなわち、左縦ビード２５の前端部分は、左閉塞部３３によって閉塞される。この左閉塞部３３は、左前隆起部１９ａが連続延長して形成されて、左閉塞部３３の底面は左前隆起部１９ａの底面１９ａｓと同一高さの面に形成されている（図４参照）。
That is, the front end portion of the left vertical bead 25 is closed by the left closing portion 33. The left front closed portion 33 is formed by continuously extending the left front raised portion 19a, and the bottom surface of the left front closed portion 33 is formed on a surface having the same height as the bottom surface 19as of the left front raised portion 19a (see FIG. 4). ..
また、右縦ビード２７の前端部分も、右閉塞部３５によって閉塞される。右閉塞部３５は、右前隆起部２１ａが連続延長して形成されて、右閉塞部３５の底面は右前隆起部２１ａの底面２１ａｓと同一高さの面に形成されている（図５参照）。
Further, the front end portion of the right vertical bead 27 is also closed by the right closing portion 35. The right front closed portion 35 is formed by continuously extending the right front raised portion 21a, and the bottom surface of the right front closed portion 35 is formed on a surface having the same height as the bottom surface 21as of the right front raised portion 21a (see FIG. 5).
このように、左縦ビード２５及び右縦ビード２７の前端部が車両前後方向に閉塞されて、蓋がされている状態であるので、左縦ビード及び右縦ビードの前端部が車両前後方向に開放される構造よりも、ストライカ９の前方側のフードインナパネル５の前部の左右方向の剛性向上が図れる。
In this way, the front ends of the left vertical bead 25 and the right vertical bead 27 are closed in the vehicle front-rear direction and the lid is closed, so that the front ends of the left vertical bead and the right vertical bead are in the vehicle front-rear direction. Rather than the open structure, the rigidity of the front portion of the hood inner panel 5 on the front side of the striker 9 can be improved in the left-right direction.
一方、左縦ビード２５及び右縦ビード２７の後端は、左縦ビード２５の後端部分では、左後隆起部１９ｂの後端を形成する段差部３７まで延びて車両前後方向に開放し、右縦ビード２７の後端部分でも、右後隆起部２１ｂの後端を形成する段差部３７まで延びて車両前後方向に開放している。
On the other hand, the rear ends of the left vertical bead 25 and the right vertical bead 27 extend to the stepped portion 37 forming the rear end of the left rear raised portion 19b at the rear end portion of the left vertical bead 25 and open in the front-rear direction of the vehicle. The rear end portion of the right vertical bead 27 also extends to the step portion 37 forming the rear end of the right rear raised portion 21b and opens in the front-rear direction of the vehicle.
このように、左縦ビード２５及び右縦ビード２７の後端部分を車両前後方向に開放構造とすることで、段差部３７まで縦ビード２５、２７を延ばしてフードインナパネル５の車両前方部１５の広い領域に渡って延ばすことができ、縦ビード２５、２７による車両前後方向の剛性向上が車両前方部１５の広い範囲で得られる。
In this way, by making the rear end portions of the left vertical bead 25 and the right vertical bead 27 open in the vehicle front-rear direction, the vertical beads 25 and 27 are extended to the step portion 37, and the vehicle front portion 15 of the hood inner panel 5 is extended. It can be extended over a wide area of the vehicle, and the vertical beads 25 and 27 can improve the rigidity in the vehicle front-rear direction in a wide area of the vehicle front portion 15.
また、左縦ビード２５に設けられる左横ビード２９、及び右縦ビード２７に設けられる右横ビード３１のいずれも、段差部２３の第２稜線Ｒ２の後方側に設けられる。これによって、ストライカ９の後側において左右方向の剛性向上が図れる。
Further, both the left horizontal bead 29 provided on the left vertical bead 25 and the right horizontal bead 31 provided on the right vertical bead 27 are provided on the rear side of the second ridge line R2 of the step portion 23. As a result, the rigidity in the left-right direction can be improved on the rear side of the striker 9.
さらに、左横ビード２９及び右横ビード３１が、段差部２３の第２稜線Ｒ２よりも後方側、つまり縦ビード２５、２７の夫々の後端部に設けられるので、横ビード２９、３１によって縦ビード２５、２７の夫々における両側壁の拡がり防止効果が効果的に得られる。
Further, since the left horizontal bead 29 and the right horizontal bead 31 are provided on the rear side of the second ridge line R2 of the step portion 23, that is, at the rear ends of the vertical beads 25 and 27, respectively, the horizontal beads 29 and 31 are used vertically. The effect of preventing the spread of both side walls in each of the beads 25 and 27 can be effectively obtained.
横ビード２９、３１の設置位置は、縦ビード２５、２７が段差部２３の第２稜線Ｒ２又は第２稜線Ｒ２の延長線を横切る領域以外に設けられるとよい。すなわち、第２稜線Ｒ２又は第２稜線Ｒ２の延長線を横切る領域に横ビード２９、３１が設置されると、第２稜線Ｒ２が横ビード２９、３１を介して縦ビード２５、２７を左右方向に渡って延びる状態になる。このようになると、第２稜線Ｒ２又は第２稜線Ｒ２の延長線を縦ビード２５、２７で分断することによって得られる第２稜線Ｒ２の部分における折れ変形の抑制効果が薄れてしまう。従って、横ビード２９、３１は、第２稜線Ｒ２又はその延長線の領域を外すことが好ましい。
The horizontal beads 29 and 31 may be installed in a region other than the region where the vertical beads 25 and 27 cross the second ridge line R2 or the extension line of the second ridge line R2 of the step portion 23. That is, when the horizontal beads 29 and 31 are installed in the region crossing the second ridge line R2 or the extension line of the second ridge line R2, the second ridge line R2 passes through the horizontal beads 29 and 31 in the left-right direction of the vertical beads 25 and 27. It will be in a state of extending over. In this case, the effect of suppressing the bending deformation in the portion of the second ridge line R2 obtained by dividing the extension line of the second ridge line R2 or the second ridge line R2 by the vertical beads 25 and 27 is diminished. Therefore, it is preferable that the lateral beads 29 and 31 exclude the region of the second ridge line R2 or its extension line.
また、図２に示すように、ストライカ９の中心Ｐｓの位置は、フードインナパネル５の上平面視において左横ビード２９の中心Ｐ１と、右横ビード３１の中心Ｐ２と、左縦ビード２５の前端部を閉塞する左閉塞部３３の中心Ｐ３と、右縦ビード２７の前端部を閉塞する右閉塞部３５の中心Ｐ４との中心位置を繋いで形成される４角形４０の内側に存在する。
Further, as shown in FIG. 2, the positions of the center Ps of the striker 9 are the center P1 of the left lateral bead 29, the center P2 of the right lateral bead 31, and the left vertical bead 25 in the upper plan view of the hood inner panel 5. It exists inside a quadrangle 40 formed by connecting the center positions of the center P3 of the left obstruction portion 33 that obstructs the front end portion and the center P4 of the right obstruction portion 35 that obstructs the front end portion of the right vertical bead 27.
このようにストライカ９の中心Ｐｓの位置を、横ビード２９、３１の中心Ｐ１、Ｐ２と、左右の閉塞部３３、３５の中心Ｐ３、Ｐ４との中心位置を、繋いで形成される４角形４０の内側に位置させことによって、ストライカ９の近傍における前後左右方向の高剛性化を実現し、フロントフード１の開閉操作時に作用する上下荷重に対して、ストライカ９の取付部周辺における応力低減を確実に発揮できる。
In this way, the quadrangle 40 formed by connecting the positions of the center Ps of the striker 9 with the centers P1 and P2 of the lateral beads 29 and 31 and the centers P3 and P4 of the left and right closed portions 33 and 35. By locating it inside the striker 9, high rigidity in the front-back and left-right directions is realized in the vicinity of the striker 9, and stress reduction around the mounting portion of the striker 9 is ensured against the vertical load acting during the opening and closing operation of the front hood 1. Can be demonstrated.
以上説明した本実施形態によれば、フロントフード１の開閉時に、ストライカ９を介して作用する荷重に対してストライカ９の近傍の強度向上を、縦ビード２５、２７と、横ビード２９、３１との簡単な構成によって発揮することができる。
According to the present embodiment described above, when the front hood 1 is opened and closed, the strength in the vicinity of the striker 9 is improved with respect to the load acting via the striker 9, with the vertical beads 25 and 27 and the horizontal beads 29 and 31. It can be demonstrated by the simple configuration of.
本発明の少なくとも一つの実施形態によれば、フロントフードの開閉時に、ストライカを介して作用する荷重に対してストライカ近傍の強度向上を、縦ビードと横ビードとの簡単な構造によって発揮することができるので、車両用フード構造への利用に適している。
According to at least one embodiment of the present invention, when the front hood is opened and closed, the strength in the vicinity of the striker can be improved against the load acting through the striker by the simple structure of the vertical bead and the horizontal bead. Since it can be used, it is suitable for use in vehicle hood structures.
