Description

本発明は、アウターパネルとインナーパネルとの間に補強部材が展開された車両用フードに関する。 The present invention relates to a vehicle hood in which a reinforcing member is deployed between an outer panel and an inner panel.

従来、車両のコンパートメント(エンジンルームやモータールームなど)の上面を覆う車両用フードにおいて、アウターパネルとインナーパネルとの間に補強部材を挿入した構造が知られている。例えば、インナーパネルにアーチ状のブラケットを固定し、ブラケットの板面をアウターパネルの裏面に沿って展開させた構造が提案されている(特許文献1参照)。また、アウターパネルの裏面に板状の補強部材を取り付けて剛性を高めた構造も提案されている(特許文献2参照)。 Conventionally, in a vehicle hood covering the upper surface of a vehicle compartment (engine room, motor room, etc.), a structure in which a reinforcing member is inserted between an outer panel and an inner panel is known. For example, a structure has been proposed in which an arch-shaped bracket is fixed to an inner panel and the plate surface of the bracket is expanded along the back surface of the outer panel (see Patent Document 1). Further, a structure in which a plate-shaped reinforcing member is attached to the back surface of the outer panel to increase the rigidity has also been proposed (see Patent Document 2).

車両用フードに外力が作用したときのエネルギーは、アウターパネルや補強部材の変形によって吸収される。したがって、その変形形状を制御することができれば、緩衝性能が向上しうる。一方、既存の車両用フードはこのような点が十分に考慮されたものとはいえず、改良の余地がある。例えば、補強部材をインナーパネルに固定するための構造に工夫を施すことで、さらなる緩衝性能の改善が期待される。 The energy when an external force acts on the vehicle hood is absorbed by the deformation of the outer panel and the reinforcing member. Therefore, if the deformed shape can be controlled, the cushioning performance can be improved. On the other hand, the existing vehicle hood cannot be said to fully consider such a point, and there is room for improvement. For example, it is expected that the cushioning performance will be further improved by devising the structure for fixing the reinforcing member to the inner panel.

本件の目的の一つは、上記のような課題に鑑みて創案されたものであり、車両用フードの補強部材の変形形状を制御して緩衝性能を向上させることである。なお、この目的に限らず、後述する「発明を実施するための形態」に示す各構成から導き出される作用効果であって、従来の技術では得られない作用効果を奏することも、本件の他の目的として位置付けることができる。 One of the purposes of this case is to improve the cushioning performance by controlling the deformed shape of the reinforcing member of the vehicle hood, which was devised in view of the above-mentioned problems. Not limited to this purpose, it is also possible to exert an action / effect derived from each configuration shown in the “mode for carrying out the invention” described later, which cannot be obtained by the conventional technique. It can be positioned as a purpose.

開示の車両用フードは、アウターパネルとインナーパネルとの間に補強部材が展開される車両用フードである。この車両用フードは、前記補強部材の前部をなし車両の前端部を補強する面状の前方面部を備える。また、前記前方面部の左右両端部のそれぞれから車両後方かつ車幅方向外側に向かって延長された面状の後方面部を備える。さらに、前記後方面部の車両外側端辺から車両前方に向かって延設され、前記インナーパネルに固定される後脚部を備える。 The disclosed vehicle hood is a vehicle hood in which a reinforcing member is deployed between the outer panel and the inner panel. The vehicle hood comprises a planar front surface portion that forms the front portion of the reinforcing member and reinforces the front end portion of the vehicle. Further, the vehicle is provided with a planar rear surface portion extending rearward of the vehicle and outward in the vehicle width direction from each of the left and right end portions of the front surface portion. Further, it includes a rear leg portion that extends from the outer side of the rear surface portion of the vehicle toward the front of the vehicle and is fixed to the inner panel.

後脚部を後方面部の車両外側端辺から車両前方に向かって延設することで、車幅方向の寸法を増大させることなく、基端部から先端までの長さを確保しやすくなる。これにより、補強部材の変形のストロークを増大させることができ、車両用フードの緩衝性能を向上させることができる。 By extending the rear legs from the outer side of the rear surface of the vehicle toward the front of the vehicle, it becomes easy to secure the length from the base end to the tip without increasing the dimension in the vehicle width direction. As a result, the deformation stroke of the reinforcing member can be increased, and the cushioning performance of the vehicle hood can be improved.

[1.車両用フードの構造]
図1〜図7を参照して、実施例としての車両用フード10を説明する。この車両用フード10は、車両の前部に設けられるコンパートメント(エンジンルームやモータールームなどの車載品収容室)の上面を被覆する部材である。コンパートメントの後端部近傍には、車体に対して車両用フード10を開閉可能に枢支するヒンジや、車両用フード10を開放方向に付勢するスプリングが設けられる。また、コンパートメントの前端部近傍には、車両用フード10の閉鎖状態を維持するためのフードロック装置や、開放状態を保持させるのに用いられるサポートロッドなどが設けられる。
[1. Structure of vehicle hood]
A vehicle hood 10 as an embodiment will be described with reference to FIGS. 1 to 7. The vehicle hood 10 is a member that covers the upper surface of a compartment (an in-vehicle product accommodating room such as an engine room or a motor room) provided in the front part of the vehicle. Near the rear end of the compartment, a hinge that pivotally supports the vehicle hood 10 with respect to the vehicle body and a spring that urges the vehicle hood 10 in the opening direction are provided. Further, in the vicinity of the front end portion of the compartment, a hood lock device for maintaining the closed state of the vehicle hood 10, a support rod used for holding the open state, and the like are provided.

図1に示すように、車両用フード10は、アウターパネル1(フードアウターパネル)とインナーパネル2(フードインナーパネル)との間に補強部材3(フードロックリンフォースアッパー)が展開された構造を持つ。アウターパネル1は車両用フード10の外表面をなす部材であり、表側の板面には意匠的な塗装や凹凸加工が施される。また、アウターパネル1の前部には、コンパートメント内に導入される冷却風が通過する開口部が形成されたグリル補強部11が設けられる。グリル補強部11には、車両のグリル12が取り付けられる。車両のヘッドランプ13は、コンパートメントよりも前方において、車体に取り付けられる。ヘッドランプ13の位置は、車両用フード10の閉鎖状態において、グリル12の左右側方となる位置に設定される。 As shown in FIG. 1, the vehicle hood 10 has a structure in which a reinforcing member 3 (hood lock reinforcement upper) is deployed between the outer panel 1 (hood outer panel) and the inner panel 2 (hood inner panel). Have. The outer panel 1 is a member forming the outer surface of the vehicle hood 10, and the plate surface on the front side is subjected to design painting or uneven processing. Further, the front portion of the outer panel 1 is provided with a grill reinforcing portion 11 having an opening through which the cooling air introduced into the compartment passes. A vehicle grill 12 is attached to the grill reinforcing portion 11. The vehicle headlamp 13 is attached to the vehicle body in front of the compartment. The position of the headlamp 13 is set to a position on the left and right sides of the grill 12 in the closed state of the vehicle hood 10.

インナーパネル2は、アウターパネル1に対して所定の間隔をあけて、その下方に配置され、アウターパネル1の外縁部に対して接合される。インナーパネル2の板面には、強度や剛性を高めるための凹凸が設けられる。本実施形態のインナーパネル2には、縁部14と梁部15とが設けられる。縁部14は、インナーパネル2の左右両端の縁に沿って形成されたほぼ水平な部位であり、補強用のフランジとして機能する。また梁部15は、板面を下方にへこませるとともに、そのへこみを縁部14の内側に沿って車両前後方向に連ねた部位であり、インナーパネル2の曲げ剛性を高める構造断面として機能する。 The inner panel 2 is arranged below the outer panel 1 at a predetermined interval, and is joined to the outer edge portion of the outer panel 1. The plate surface of the inner panel 2 is provided with irregularities for increasing strength and rigidity. The inner panel 2 of the present embodiment is provided with an edge portion 14 and a beam portion 15. The edge portion 14 is a substantially horizontal portion formed along the edges of the left and right ends of the inner panel 2, and functions as a reinforcing flange. Further, the beam portion 15 is a portion where the plate surface is dented downward and the dents are connected in the front-rear direction of the vehicle along the inside of the edge portion 14, and functions as a structural cross section for increasing the bending rigidity of the inner panel 2. ..

補強部材3は、アウターパネル1とインナーパネル2とで囲まれた空間内において、アウターパネル1の板面に沿って面状に配置される。補強部材3の材質は、アルミ合金(例えば、Al-Mg系合金やAl-Mg-Si系合金など)であり、圧延板を加工して形成される。補強部材3は、アウターパネル1やインナーパネル2に対して固定される。例えば、本実施形態の補強部材3は、アウターパネル1に対してマスチック接着剤で固定されるとともに、インナーパネル2に対して溶接固定される。 The reinforcing member 3 is arranged in a plane shape along the plate surface of the outer panel 1 in the space surrounded by the outer panel 1 and the inner panel 2. The material of the reinforcing member 3 is an aluminum alloy (for example, an Al-Mg-based alloy, an Al-Mg-Si-based alloy, etc.), and is formed by processing a rolled plate. The reinforcing member 3 is fixed to the outer panel 1 and the inner panel 2. For example, the reinforcing member 3 of the present embodiment is fixed to the outer panel 1 with a mastic adhesive and is fixed to the inner panel 2 by welding.

車両の上面視における補強部材3の全体形状は、弓なりに湾曲したブーメラン形状に準えられ、車幅方向の中央部付近が車両前方に飛び出すようなレイアウトで配置される。また、補強部材3の形状は、車両の上面視で左右対称(鏡面対称)である。図2に示すように、本実施形態の補強部材3は、前方面部4と一対の後方面部5とを有する。前方面部4とは、補強部材3のうち車両前部に位置する半月状の部位である。また、後方面部5とは、その左右両端部のそれぞれから、車両後方かつ車幅方向外側に向かって延長された部位である。前方面部4と後方面部5との境界線を、図2中に一点鎖線で例示する。ただし、前方面部4及び後方面部5は一体に形成されており、これらの境界は便宜的に定めたものに過ぎない。 The overall shape of the reinforcing member 3 in the top view of the vehicle is similar to the boomerang shape curved in a bow shape, and is arranged so that the vicinity of the central portion in the vehicle width direction protrudes in front of the vehicle. Further, the shape of the reinforcing member 3 is symmetrical (mirror plane symmetry) when viewed from the top of the vehicle. As shown in FIG. 2, the reinforcing member 3 of the present embodiment has a front surface portion 4 and a pair of rear surface portions 5. The front surface portion 4 is a half-moon-shaped portion of the reinforcing member 3 located at the front portion of the vehicle. The rear surface portion 5 is a portion extending rearward of the vehicle and outward in the vehicle width direction from each of the left and right end portions thereof. The boundary line between the front surface portion 4 and the rear surface portion 5 is illustrated by a alternate long and short dash line in FIG. However, the front surface portion 4 and the rear surface portion 5 are integrally formed, and their boundaries are merely defined for convenience.

補強部材3には、インナーパネル2に固定される三対の脚部6,7,8が設けられる。これらの脚部6,7,8は、補強部材3からその外側かつ下方に向かって斜めに延設される。以下、前方面部4に設けられる脚部を前脚部6と呼ぶ。また、後方面部5に設けられる脚部のうち、車両外側に位置するものを後脚部7と呼び、車両内側に位置するものを第二後脚部8と呼ぶ。 The reinforcing member 3 is provided with three pairs of legs 6, 7, and 8 fixed to the inner panel 2. These legs 6, 7, and 8 extend diagonally outward and downward from the reinforcing member 3. Hereinafter, the leg portion provided on the front surface portion 4 is referred to as a front leg portion 6. Further, among the legs provided on the rear surface portion 5, those located on the outside of the vehicle are referred to as rear leg portions 7, and those located on the inside of the vehicle are referred to as second rear leg portions 8.

前脚部6は、前方面部4の前端部であって、グリル補強部11の左右両側方(グリル12を避けた位置)に配置される。車両の上面視における前脚部6の位置は、図2に示すように、ヘッドランプ13の裏側に相当する位置である。前脚部6の先端は、インナーパネル2の縁部14に対して面接触した状態で固定され、例えばスポット溶接で固定される。車両の上面視で前方面部4から前脚部6が伸びる方向は、斜め前方(車両外側かつ前方へ向かう方向)とされる。 The front leg portion 6 is a front end portion of the front surface portion 4, and is arranged on both the left and right sides of the grill reinforcing portion 11 (positions avoiding the grill 12). As shown in FIG. 2, the position of the front leg portion 6 in the top view of the vehicle is a position corresponding to the back side of the headlamp 13. The tip of the front leg portion 6 is fixed in a state of being in surface contact with the edge portion 14 of the inner panel 2, and is fixed by spot welding, for example. The direction in which the front leg portion 6 extends from the front surface portion 4 in the top view of the vehicle is defined as diagonally forward (direction toward the outside and front of the vehicle).

前方面部4の前端辺のうち左右の前脚部6によって挟まれた部分には、下方に向かって折り曲げられたフランジ16が形成される。ただし、フランジ16の左右両端部は、前脚部6に達する手前で途切れている。前方面部4の前端辺のうち、前脚部6に隣接する車両中央側の部位には、フランジ16が形成されない。一方、前脚部6に隣接する車両外側の部位には、第二フランジ17が形成される。第二フランジ17は、前方面部4の左右側端辺を下方に向かって折り曲げて形成された部位であり、前脚部6の板面につながるように設けられる。第二フランジ17の後端部は、後方面部5に達する手前で途切れている。 A flange 16 bent downward is formed at a portion of the front end side of the front surface portion 4 sandwiched by the left and right front leg portions 6. However, the left and right ends of the flange 16 are interrupted before reaching the front leg portion 6. Of the front end sides of the front surface portion 4, the flange 16 is not formed on the portion on the vehicle center side adjacent to the front leg portion 6. On the other hand, a second flange 17 is formed at a portion on the outside of the vehicle adjacent to the front leg portion 6. The second flange 17 is a portion formed by bending the left and right side ends of the front surface portion 4 downward, and is provided so as to be connected to the plate surface of the front leg portion 6. The rear end portion of the second flange 17 is interrupted before reaching the rear surface portion 5.

後脚部7及び第二後脚部8は、後方面部5から延設される。後脚部7は、後方面部5の車両外側端辺のうち、車両後方寄り(端部寄り)の位置に配置される。これに対し、第二後脚部8は、後方面部5の車両内側端辺のうち、車両後方寄り(端部寄り)の位置に配置される。大まかにいえば、後脚部7及び第二後脚部8の位置は、ブーメラン形状における左右両端部(二つの先端)に相当する位置に設定される。また、ブーメラン形状の外側に配置されるのが後脚部7であり、ブーメラン形状の内側に配置されるのが第二後脚部8である。 The rear leg portion 7 and the second rear leg portion 8 extend from the rear surface portion 5. The rear leg portion 7 is arranged at a position closer to the rear of the vehicle (closer to the end portion) than the outer side edge of the vehicle on the rear surface portion 5. On the other hand, the second rear leg portion 8 is arranged at a position closer to the rear of the vehicle (closer to the end portion) than the inner end side of the vehicle of the rear surface portion 5. Roughly speaking, the positions of the rear leg portion 7 and the second rear leg portion 8 are set to positions corresponding to the left and right end portions (two tips) in the boomerang shape. Further, the rear leg portion 7 is arranged outside the boomerang shape, and the second rear leg portion 8 is arranged inside the boomerang shape.

車両の上面視で後方面部5から第二後脚部8が伸びる方向は、前脚部6とは正反対の方向であって、斜め後方(車両内側かつ後方へ向かう方向)とされる。また、後方面部5から後脚部7が伸びる方向は、車両前方とされる。これにより、後脚部7の基端から先端までの距離が長くなり、外力作用時における変形のストロークが大きくなる。また、後脚部7を車幅方向外側に伸ばした場合と比較して、後脚部7の車幅方向への突出が抑制される。 The direction in which the second rear leg portion 8 extends from the rear surface portion 5 in the top view of the vehicle is the direction opposite to that of the front leg portion 6 and is diagonally rearward (the direction toward the inside and the rear of the vehicle). Further, the direction in which the rear leg portion 7 extends from the rear surface portion 5 is defined as the front of the vehicle. As a result, the distance from the base end to the tip end of the rear leg portion 7 becomes long, and the deformation stroke when an external force is applied becomes large. Further, as compared with the case where the rear leg portion 7 is extended outward in the vehicle width direction, the protrusion of the rear leg portion 7 in the vehicle width direction is suppressed.

後脚部7の先端は、インナーパネル2の縁部14に対して面接触した状態で固定(例えばスポット溶接)される。一方、第二後脚部8の先端は、インナーパネル2の板面に対して面接触した状態で固定され、例えばスポット溶接で固定される。また、図2に示すように、後方面部5の車両外側端辺には、第二フランジ17が形成されない。つまり、後方面部5と後脚部7との境界付近には断面二次モーメントを増加させるための補強構造をあえて適用しないことで、曲げ変形を許容している。 The tip of the rear leg portion 7 is fixed (for example, spot welded) in a state of being in surface contact with the edge portion 14 of the inner panel 2. On the other hand, the tip of the second rear leg portion 8 is fixed in a state of being in surface contact with the plate surface of the inner panel 2, and is fixed by spot welding, for example. Further, as shown in FIG. 2, the second flange 17 is not formed on the outer side of the vehicle on the rear surface portion 5. That is, bending deformation is allowed by not intentionally applying a reinforcing structure for increasing the moment of inertia of area near the boundary between the rear surface portion 5 and the rear leg portion 7.

前方面部4の後端辺や後方面部5の車両内側端辺には、階段状に形成された階段フランジ18が設けられる。階段フランジ18は、前方面部4や後方面部5の板面を下方及び車両後方に向かってクランク状に屈曲させた部位であり、第二後脚部8の板面につながるように形成される。これにより、補強部材3の端辺のうち、ブーメラン形状の内側に相当する全範囲が曲げ変形しにくい構造となる。 A staircase flange 18 formed in a staircase shape is provided on the rear end side of the front surface portion 4 and the vehicle inner end side of the rear surface portion 5. The staircase flange 18 is a portion where the plate surfaces of the front surface portion 4 and the rear surface portion 5 are bent downward and toward the rear of the vehicle in a crank shape, and is formed so as to be connected to the plate surface of the second rear leg portion 8. NS. As a result, of the end sides of the reinforcing member 3, the entire range corresponding to the inside of the boomerang shape becomes a structure that is not easily bent and deformed.

[2.後脚部の構造]
後脚部7は、補強部材3の後方面部5の縁端から面状に延設されて、インナーパネル2の縁部14に固定される。前述の通り、後脚部7は後方面部5の車両外側端辺のうち、車両後方寄り(端部寄り)の位置に配置され、車両前方に向かって延設される。前脚部6と同様に後脚部7は、補強部材3の板面の端部にプレス加工を施すことで成形することができる。図3〜図6に示すように、後脚部7には、上から順に後脚第一面部40,後脚第二面部41,後脚第三面部42が設けられる。
[2. Structure of hind legs]
The rear leg portion 7 extends in a planar shape from the edge portion of the rear surface portion 5 of the reinforcing member 3 and is fixed to the edge portion 14 of the inner panel 2. As described above, the rear leg portion 7 is arranged at a position closer to the rear side of the vehicle (closer to the end portion) than the outer side edge of the vehicle on the rear surface portion 5, and extends toward the front of the vehicle. Similar to the front leg portion 6, the rear leg portion 7 can be formed by pressing the end portion of the plate surface of the reinforcing member 3. As shown in FIGS. 3 to 6, the rear leg portion 7 is provided with the rear leg first surface portion 40, the rear leg second surface portion 41, and the rear leg third surface portion 42 in this order from the top.

後脚第一面部40(第一面部)は、後脚部7の最上部に設けられる面状の部位である。この後脚第一面部40は、後方面部5と同一平面をなすように、後方面部5の縁端から延設される。後方面部5と後脚第一面部40との境界50は直線状であり、図4,図5中に破線で示す。なお、後脚第一面部40と後脚第二面部41との境界は、この境界50(後方面部5の車両外側端辺)に対して平行に配置される。言い換えると、後脚第一面部40の形状は長方形の平面状であり、境界50に接する辺がこれに隣接する辺よりも長くなるように形成される。 The rear leg first surface portion 40 (first surface portion) is a planar portion provided at the uppermost portion of the rear leg portion 7. The rear leg first surface portion 40 extends from the edge of the rear surface portion 5 so as to form the same plane as the rear surface portion 5. The boundary 50 between the rear surface portion 5 and the rear leg first surface portion 40 is a straight line, and is shown by a broken line in FIGS. 4 and 5. The boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41 is arranged parallel to this boundary 50 (the vehicle outer end side of the rear surface portion 5). In other words, the shape of the first surface portion 40 of the rear leg is a rectangular planar shape, and the side in contact with the boundary 50 is formed to be longer than the side adjacent to the boundary 50.

後脚第二面部41(第二面部)は、後脚第一面部40に隣接してその下方に設けられる面状の部位である。この後脚第二面部41は、後脚第一面部40に対して傾斜した向きで斜めに接続される。後脚第二面部41の大まかな形状は、車両前方に向かって伸びた平行四辺形状に準えることができる。少なくとも、後脚第二面部41と後脚第三面部42との境界は、後脚第一面部40と後脚第二面部41との境界に対して平行に配置される。なお、基端側(後脚第一面部40側)の幅を先端側(後脚第三面部42側)よりも狭く形成することで、後脚第二面部41の変形しやすさを向上させてもよい。 The rear leg second surface portion 41 (second surface portion) is a planar portion provided adjacent to the rear leg first surface portion 40 and below the rear leg first surface portion 40. The rear leg second surface portion 41 is obliquely connected to the rear leg first surface portion 40 in an inclined direction. The rough shape of the second surface portion 41 of the rear leg can conform to the parallel four-sided shape extending toward the front of the vehicle. At least, the boundary between the rear leg second surface portion 41 and the rear leg third surface portion 42 is arranged parallel to the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. By forming the width of the base end side (rear leg first surface portion 40 side) narrower than that of the tip end side (rear leg third surface portion 42 side), the deformability of the rear leg second surface portion 41 is improved.

図4に示すように、後脚第一面部40と後脚第二面部41との境界をなす第三屈曲部43は、山折りの稜線(上に凸の折れ目)となる。後脚第一面部40に対する後脚第二面部41の屈曲角度θ4は、図6(B)に示すように、少なくとも直角よりも浅い角度(例えば、10〜80°)に設定される。第三屈曲部43が境界50から離れた位置(車両外側)にずれていることから、外力作用時には境界50での屈曲変形が相対的に誘発されやすくなる。As shown in FIG. 4, the third bent portion 43 forming the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41 is a ridgeline of a mountain fold (a fold that is convex upward). As shown in FIG. 6B, the bending angle θ 4 of the rear leg second surface portion 41 with respect to the rear leg first surface portion 40 is set to an angle shallower than at least a right angle (for example, 10 to 80 °). Since the third bent portion 43 is displaced to a position away from the boundary 50 (outside the vehicle), bending deformation at the boundary 50 is relatively likely to be induced when an external force is applied.

後脚第三面部42(第三面部)は、後脚第二面部41に隣接してその下方に設けられる面状の部位である。この後脚第三面部42は、後脚第一面部40に対して傾斜した向きで斜めに接続されるが、後脚第二面部41に対する後脚第三面部42の屈曲方向は、後脚第一面部40に対する後脚第二面部41の屈曲方向とは逆方向に設定される。これにより、後脚第二面部41と後脚第三面部42との境界をなす第四屈曲部44は、谷折りの溝(下に凸の折れ目)となる。 The rear leg third surface portion 42 (third surface portion) is a planar portion provided adjacent to the rear leg second surface portion 41 and below the rear leg second surface portion 41. The rear leg third surface portion 42 is diagonally connected to the rear leg first surface portion 40 in an inclined direction, but the bending direction of the rear leg third surface portion 42 with respect to the rear leg second surface portion 41 is the rear leg. It is set in the direction opposite to the bending direction of the rear leg second surface portion 41 with respect to the first surface portion 40. As a result, the fourth bent portion 44 forming the boundary between the second surface portion 41 of the rear leg and the third surface portion 42 of the rear leg becomes a valley fold groove (a downwardly convex fold).

本実施形態では、後脚第二面部41に対する後脚第三面部42の屈曲角度θ5が、直角よりも浅い角度であって、後脚第二面部41の屈曲角度θ4と同一の角度に設定される。すなわち、θ45である。後脚第二面部41の折り曲げが、後脚第三面部42の折り曲げによって元に戻される。これにより、後脚第三面部42の姿勢が後脚第一面部40と同じようにほぼ水平となり、インナーパネル2の縁部14に面接触しやすい向きとなる。また、後脚第三面部42を後方面部5に対して平行にすることで、補強部材3の固定状態が安定する。 In the present embodiment, the bending angle θ 5 of the rear leg third surface portion 42 with respect to the rear leg second surface portion 41 is shallower than a right angle and is the same as the bending angle θ 4 of the rear leg second surface portion 41. Set. That is, θ 4 = θ 5 . The bending of the rear leg second surface portion 41 is restored by the bending of the rear leg third surface portion 42. As a result, the posture of the rear leg third surface portion 42 becomes substantially horizontal as in the rear leg first surface portion 40, and the orientation is such that surface contact with the edge portion 14 of the inner panel 2 is likely to occur. Further, by making the rear leg third surface portion 42 parallel to the rear surface portion 5, the fixed state of the reinforcing member 3 is stabilized.

図3〜図5に示すように、後脚部7と後方面部5との間には切り込み部45が設けられる。切り込み部45とは、後脚部7とインナーパネル2との固定位置よりも車両後方まで切り込んだ形状に形成された部位であって、上面視で車両後方に向かって窪んだ入り江のような形状を有する。また、後方面部5及び後脚部7の縁部のうち、切り込み部45に接する部位には、フランジやビードなどの補強構造が適用されない。例えば、第二フランジ17は上面視で第三面部42よりも車両後方の範囲には進入しておらず、切り込み部45よりも車両前方のみに配置されている。 As shown in FIGS. 3 to 5, a notch 45 is provided between the rear leg portion 7 and the rear surface portion 5. The cut portion 45 is a portion formed in a shape that is cut to the rear of the vehicle from the fixed position of the rear leg portion 7 and the inner panel 2, and has a shape like a cove that is recessed toward the rear of the vehicle when viewed from above. Have. Further, of the edges of the rear surface portion 5 and the rear leg portion 7, a reinforcing structure such as a flange or a bead is not applied to a portion in contact with the notch portion 45. For example, the second flange 17 does not enter the range behind the vehicle from the third surface portion 42 when viewed from above, and is arranged only in front of the vehicle from the notch portion 45.

図6(A)に示すように、第三屈曲部43には第三ビード46,第四ビード47が設けられる。これらのビード46,47は、後脚第一面部40と後脚第二面部41との境界において、下方のインナーパネル2側に膨出した形状に形成される。ビード46,47の形状は、横方向に細長い楕円形状や円形,卵形などに設定される。このようなビード46,47を設けることで、外力作用時における第三屈曲部43の変形が減少し、後脚第一面部40及び後脚第二面部41の屈曲角度θ4が維持されやすくなる。As shown in FIG. 6A, the third bent portion 43 is provided with a third bead 46 and a fourth bead 47. These beads 46 and 47 are formed in a shape bulging toward the lower inner panel 2 at the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. The shapes of the beads 46 and 47 are set to be an elliptical shape elongated in the lateral direction, a circular shape, an oval shape, or the like. By providing such beads 46 and 47, the deformation of the third bent portion 43 at the time of external force action is reduced, and the bending angle θ 4 of the rear leg first surface portion 40 and the rear leg second surface portion 41 can be easily maintained. Become.

本実施形態では、複数のビード46,47が後脚第一面部40と後脚第二面部41との境界に設けられる。これらのビード46,47は、ともに第三屈曲部43に配置される。したがって、二つのビード46,47を結ぶラインは、境界50や第四屈曲部44の延在方向と平行になる。複数のビード46,47を設けることで、外力作用時における第三屈曲部43の変形がさらに抑制される。 In the present embodiment, a plurality of beads 46, 47 are provided at the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. Both of these beads 46 and 47 are arranged at the third bent portion 43. Therefore, the line connecting the two beads 46 and 47 is parallel to the extending direction of the boundary 50 and the fourth bent portion 44. By providing the plurality of beads 46 and 47, the deformation of the third bent portion 43 at the time of external force action is further suppressed.

後脚第二面部41及び後脚第三面部42には、後脚部7の端辺(補強部材3とインナーパネル2との間をつなぐ端辺)を補強するための第四補強部48,第五補強部49が設けられる。これらの補強部48,49は、板面を屈曲させてなる部位であり、後脚部7の端辺に沿って形成される。本実施形態の補強部48,49は、後脚第二面部41,後脚第三面部42の板面を***させた形状を有する。すなわち、板面を二回屈曲させることで、断面形状をクランク状にしている。後脚第三面部42の断面形状は、図6(C)に示すように、左右両端部が中央部よりも***した形状(上下逆向きのハット形)に形成される。 The second surface portion 41 of the rear leg and the third surface portion 42 of the rear leg have a fourth reinforcing portion 48 for reinforcing the end edge of the rear leg portion 7 (the end edge connecting the reinforcing member 3 and the inner panel 2). A fifth reinforcing portion 49 is provided. These reinforcing portions 48 and 49 are portions formed by bending the plate surface, and are formed along the end edges of the rear leg portions 7. The reinforcing portions 48 and 49 of the present embodiment have a shape in which the plate surfaces of the rear leg second surface portion 41 and the rear leg third surface portion 42 are raised. That is, the cross-sectional shape is made into a crank shape by bending the plate surface twice. As shown in FIG. 6C, the cross-sectional shape of the third surface portion 42 of the rear leg is formed so that both the left and right ends are raised from the central portion (hat shape upside down).

第四補強部48は、後脚第二面部41の端辺のうち、車幅方向外側の第一端辺51に設けられる。また、後脚第二面部41の第一端辺51に隣接する後脚第三面部42の端辺にも、第四補強部48が延設される。第四補強部48は、後脚第二面部41及び後脚第三面部42の外側端辺を補強して、外側端辺近傍での曲げ変形を抑制するように機能する。 The fourth reinforcing portion 48 is provided on the first end side 51 on the outer side in the vehicle width direction among the end sides of the rear leg second surface portion 41. Further, the fourth reinforcing portion 48 is also extended to the end side of the rear leg third surface portion 42 adjacent to the first end side 51 of the rear leg second surface portion 41. The fourth reinforcing portion 48 functions to reinforce the outer end sides of the rear leg second surface portion 41 and the rear leg third surface portion 42 to suppress bending deformation in the vicinity of the outer end side.

第五補強部49は、後脚第二面部41及び後脚第三面部42の端辺に設けられる。しかし、後脚第二面部41の第一端辺51に対向する第二端辺52にはほとんど第五補強部49が含まれないように、第五補強部49の範囲が設定される。例えば図5に示すように、後脚第二面部41の第二端辺52のうち、後脚第三面部42から直線状に伸びた部分のみに第五補強部49が設けられる。第二端辺52の大半は第五補強部49が設けられず、すなわち板面を屈曲させていない平面状の非補強部となる。 The fifth reinforcing portion 49 is provided on the end sides of the rear leg second surface portion 41 and the rear leg third surface portion 42. However, the range of the fifth reinforcing portion 49 is set so that the second end side 52 facing the first end side 51 of the rear leg second surface portion 41 hardly includes the fifth reinforcing portion 49. For example, as shown in FIG. 5, the fifth reinforcing portion 49 is provided only on the portion of the second end side 52 of the rear leg second surface portion 41 that extends linearly from the rear leg third surface portion 42. Most of the second end side 52 is not provided with the fifth reinforcing portion 49, that is, it is a flat non-reinforcing portion in which the plate surface is not bent.

[3.作用,効果]
図7は、車両用フード10の上方からアウターパネル1に外力が作用したときの後脚部7の変形状態を例示する図である。後脚第二面部41の第一端辺51は、第四補強部48によって補強されているため変形しにくく、姿勢が維持されやすい。一方、後脚部7と後方面部5との間には切り込み部45が設けられ、後脚第二面部41の第二端辺52にはほとんど第五補強部49が含まれない。これにより、第二端辺52側での屈曲変形が許容されやすくなる。
[3. Action, effect]
FIG. 7 is a diagram illustrating a deformed state of the rear leg portion 7 when an external force acts on the outer panel 1 from above the vehicle hood 10. Since the first end side 51 of the rear leg second surface portion 41 is reinforced by the fourth reinforcing portion 48, it is difficult to be deformed and the posture is easily maintained. On the other hand, a notch 45 is provided between the rear leg portion 7 and the rear surface portion 5, and the second end side 52 of the rear leg second surface portion 41 hardly includes the fifth reinforcing portion 49. This makes it easier to allow bending deformation on the second end side 52 side.

また、第三屈曲部43には第三ビード46,第四ビード47が設けられることから、後脚第一面部40及び後脚第二面部41の屈曲角度θ4が維持されやすくなる。これにより、図7に示すように、境界50付近が第三屈曲部43よりも屈曲しやすくなり、境界50付近が谷折りの溝(下に凸の折れ目)となる。これにより、第三屈曲部43が後方面部5よりも上方へと移動することになり、変形のストロークが増大する。なお、後方面部5及び後脚部7の縁部のうち、切り込み部45に接する部位には、フランジやビードなどの補強構造が適用されない。したがって、後脚部7の変形時における、インナーパネル2との意図しない干渉や接触が防止され、後脚部7の緩衝性能が向上する。Further, since the third bead 46 and the fourth bead 47 are provided on the third bent portion 43, the bending angle θ 4 of the rear leg first surface portion 40 and the rear leg second surface portion 41 can be easily maintained. As a result, as shown in FIG. 7, the vicinity of the boundary 50 becomes easier to bend than the third bent portion 43, and the vicinity of the boundary 50 becomes a valley fold groove (a downwardly convex fold). As a result, the third bent portion 43 moves upward from the rear surface portion 5, and the deformation stroke increases. Of the edges of the rear surface portion 5 and the rear leg portion 7, a reinforcing structure such as a flange or a bead is not applied to a portion in contact with the notch portion 45. Therefore, when the rear leg portion 7 is deformed, unintended interference or contact with the inner panel 2 is prevented, and the cushioning performance of the rear leg portion 7 is improved.

(1)上記の車両用フード10の補強部材3には、前方面部4と後方面部5とが設けられる。後方面部5は、前方面部4の左右両端部のそれぞれから車両後方かつ車幅方向外側に向かって延長された面状の部位である。この後方面部5の車両外側端辺から、車両前方に向かって後脚部7が延設され、インナーパネル2に固定される。このような構成により、後脚部7の車幅方向への突出を抑制しつつ、後脚部7の基端から先端までの距離を長くすることができる。したがって、外力作用時における後脚部7及び補強部材3の変形のストロークを増大させることができ、車両用フード10の緩衝性能を向上させることができる。 (1) The reinforcing member 3 of the vehicle hood 10 is provided with a front surface portion 4 and a rear surface portion 5. The rear surface portion 5 is a planar portion extending rearward of the vehicle and outward in the vehicle width direction from each of the left and right end portions of the front surface portion 4. The rear leg portion 7 extends from the outer end side of the rear surface portion 5 toward the front of the vehicle and is fixed to the inner panel 2. With such a configuration, it is possible to increase the distance from the base end to the tip end of the rear leg portion 7 while suppressing the protrusion of the rear leg portion 7 in the vehicle width direction. Therefore, it is possible to increase the deformation stroke of the rear leg portion 7 and the reinforcing member 3 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(2)図3〜図5に示すように、後脚部7と後方面部5との間には切り込み部45が設けられる。これにより、上面視における後脚部7を車両前後方向に細長い形状にすることができ、車幅方向寸法が小さく長い脚を形成することができる。また、切り込み部45を設けることで、後脚部7での応力伝達方向を車両前後方向に制限することができる。これにより、外力作用時における後脚部7及び補強部材3の変形のストロークを増大させることができ、車両用フード10の緩衝性能を向上させることができる。 (2) As shown in FIGS. 3 to 5, a notch 45 is provided between the rear leg portion 7 and the rear surface portion 5. As a result, the rear leg portion 7 in the top view can be formed into an elongated shape in the vehicle front-rear direction, and a long leg having a small vehicle width direction can be formed. Further, by providing the notch portion 45, the stress transmission direction in the rear leg portion 7 can be limited to the vehicle front-rear direction. As a result, it is possible to increase the deformation stroke of the rear leg portion 7 and the reinforcing member 3 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(3)図6(B)に示すように、後脚部7は、車両外側に向かう下り勾配で傾斜した姿勢で配置される。これにより、後脚部7の板面が下方に落ち込むように変形させることが容易となり、補強部材3の変形形状の制御性を高めることができる。また、補強部材3に入力された外力を車両外側に分散させやすくすることができ、車両用フード10の緩衝性能を向上させることができる。 (3) As shown in FIG. 6B, the rear leg portion 7 is arranged in an inclined posture with a downward slope toward the outside of the vehicle. This makes it easy to deform the plate surface of the rear leg portion 7 so as to drop downward, and it is possible to improve the controllability of the deformed shape of the reinforcing member 3. Further, the external force input to the reinforcing member 3 can be easily dispersed to the outside of the vehicle, and the cushioning performance of the vehicle hood 10 can be improved.

(4)図6(B)に示すように、後脚部7には、後脚第一面部40,後脚第二面部41,後脚第三面部42が設けられる。これらの面部40〜42のうち、インナーパネル2に固定されているのは後脚第三面部42のみである。また、後脚第一面部40は後方面部5と同一平面をなすように設けられる。このような構成により、外力作用時に境界50付近を屈曲させやすくすることができ、後脚部7を意図した通りに変形させることができる。したがって、車両用フード10の緩衝性能を向上させることができる。 (4) As shown in FIG. 6B, the rear leg portion 7 is provided with a rear leg first surface portion 40, a rear leg second surface portion 41, and a rear leg third surface portion 42. Of these face portions 40 to 42, only the rear leg third surface portion 42 is fixed to the inner panel 2. Further, the rear leg first surface portion 40 is provided so as to form the same plane as the rear surface portion 5. With such a configuration, it is possible to easily bend the vicinity of the boundary 50 when an external force is applied, and the hind leg portion 7 can be deformed as intended. Therefore, the cushioning performance of the vehicle hood 10 can be improved.

(5)後脚第二面部41の第一端辺51には、板面を屈曲させてなる第四補強部48が設けられる。一方、第一端辺51に対向する第二端辺52には、板面を屈曲させていない非補強部が設けられる。このような構成により、第一端辺51での屈曲変形を抑制しつつ、第二端辺52側のみでの屈曲変形を促進することができ、後脚部7を意図した通りに変形させることができる。例えば、第三屈曲部43が後方面部5よりも上方へと移動するように、後脚部7を屈曲変形させることができる。したがって、外力作用時における後脚部7の変形のストロークを増大させることができ、車両用フード10の緩衝性能を向上させることができる。 (5) A fourth reinforcing portion 48 formed by bending the plate surface is provided on the first end side 51 of the rear leg second surface portion 41. On the other hand, the second end side 52 facing the first end side 51 is provided with a non-reinforcing portion in which the plate surface is not bent. With such a configuration, it is possible to promote bending deformation only on the second end side 52 side while suppressing bending deformation on the first end side 51, and to deform the hind leg portion 7 as intended. Can be done. For example, the rear leg portion 7 can be flexed and deformed so that the third bent portion 43 moves above the rear surface portion 5. Therefore, it is possible to increase the deformation stroke of the rear leg portion 7 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(6)図5に示すように、後脚第一面部40と後脚第二面部41との境界をなす境界部(第三屈曲部43)は、境界50(後方面部5の車両外側端辺)に対して平行に配置される。これにより、外力作用時に境界50付近の全体を屈曲させやすくすることができる。つまり、外力作用時における後脚部7の変形のストロークを増大させることができ、車両用フード10の緩衝性能を向上させることができる。 (6) As shown in FIG. 5, the boundary portion (third bent portion 43) forming the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41 is the boundary 50 (the outside of the vehicle of the rear surface portion 5). Arranged parallel to the edge). As a result, it is possible to easily bend the entire vicinity of the boundary 50 when an external force is applied. That is, it is possible to increase the deformation stroke of the rear leg portion 7 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(7)同様に、後脚第二面部41と後脚第三面部42との境界は、後脚第一面部40と後脚第二面部41との境界に対して平行に配置される。このような構成により、後脚第二面部41を板面に垂直な方向(座屈方向)に変形しやすくすることができる。したがって、外力作用時における後脚部7の変形のストロークを増大させることができ、車両用フード10の緩衝性能を向上させることができる。 (7) Similarly, the boundary between the rear leg second surface portion 41 and the rear leg third surface portion 42 is arranged parallel to the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. With such a configuration, the rear leg second surface portion 41 can be easily deformed in the direction perpendicular to the plate surface (buckling direction). Therefore, it is possible to increase the deformation stroke of the rear leg portion 7 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(8)第三屈曲部43に第三ビード46,第四ビード47を設けることで、後脚第一面部40の下端(後脚第二面部41の上端)での変形を抑制することができ、屈曲角度θ4を維持しやすくすることができる。これにより、境界50付近での屈曲変形を促進することができ、後脚部7の変形のストロークを増大させることができる。また、第三屈曲部43の屈曲角度θ4が維持されやすくなることから、第三屈曲部43が後方面部5よりも下方に落ち込むような変形を抑制することができ、後脚部7を意図した通りに変形させることができる。したがって、車両用フード10の緩衝性能を向上させることができる。(8) By providing the third bead 46 and the fourth bead 47 on the third bent portion 43, deformation at the lower end of the rear leg first surface portion 40 (the upper end of the rear leg second surface portion 41) can be suppressed. It is possible to easily maintain the bending angle θ 4. As a result, bending deformation near the boundary 50 can be promoted, and the deformation stroke of the hind leg portion 7 can be increased. Further, since the bending angle θ 4 of the third bending portion 43 can be easily maintained, it is possible to suppress the deformation that the third bending portion 43 falls below the rear surface portion 5, and the rear leg portion 7 can be formed. It can be transformed as intended. Therefore, the cushioning performance of the vehicle hood 10 can be improved.

(9)なお、複数のビード46,47を設けることで、外力作用時における第三屈曲部43の変形を強く抑制することができ、より確実に後脚部7を意図した通りに変形させることができる。したがって、車両用フード10の緩衝性能を向上させることができる。特に、第三屈曲部43が屈曲して下方へ落ち込み、後脚部7の変形のストロークが小さくなってしまうような事態を防止することができる。 (9) By providing the plurality of beads 46 and 47, the deformation of the third bent portion 43 at the time of external force action can be strongly suppressed, and the rear leg portion 7 can be more reliably deformed as intended. Can be done. Therefore, the cushioning performance of the vehicle hood 10 can be improved. In particular, it is possible to prevent a situation in which the third bent portion 43 bends and falls downward, resulting in a small deformation stroke of the rear leg portion 7.
