Description

本発明は、車両前側のフェンダパネルを支持するフェンダ取付ブラケットの衝撃吸収性を高める車両側部構造に関する。 The present invention relates to a vehicle side structure that enhances shock absorption of a fender mounting bracket that supports a fender panel on the front side of the vehicle.

車両のエンジンルームでは、上方をフードに覆われ、側方にはフェンダパネルが配置されている。フェンダパネルは、エプロンメンバから上方に延設されるフェンダ取付ブラケットに取り付けられる。フードあるいはフェンダパネルに対して上方から衝突荷重がかかったとき、フェンダ取付ブラケットが座屈することにより、衝撃を吸収する。 In the engine room of the vehicle, the upper part is covered with a hood and the fender panel is arranged on the side. The fender panel is attached to a fender mounting bracket that extends upward from the apron member. When a collision load is applied to the hood or fender panel from above, the fender mounting bracket buckles to absorb the impact.

フェンダ取付ブラケットには、荷重がかかったとき、安定して座屈することが求められる。特許文献１には、フェンダ取付ブラケットの中途部に屈曲部が形成され、衝撃荷重がかかると、屈曲部を起点としてフェンダ取付ブラケットを下方に座屈させることが記載されている。 The fender mounting bracket is required to stably buckle when a load is applied. Patent Document 1 describes that a bent portion is formed in the middle of the fender mounting bracket, and when an impact load is applied, the fender mounting bracket is buckled downward with the bent portion as a starting point.

特開２０１７－８１３９６号公報JP-A-2017-81396

車両の意匠上、フェンダパネルが高くなると、エプロンメンバからフェンダパネルまでの距離が長くなり、フェンダ取付ブラケットを上方に延ばす必要が生じる。長くなったフェンダ取付ブラケットの中途部に屈曲部を形成すると、通常使用時のフェンダ取付ブラケットの手押し剛性を確保しにくくなる。手押し剛性を確保するために、フェンダ取付ブラケットを強度の高い材質に変更したり、板厚を増やすと、座屈しにくくなる。 Due to the design of the vehicle, when the fender panel is raised, the distance from the apron member to the fender panel becomes long, and it becomes necessary to extend the fender mounting bracket upward. If a bent portion is formed in the middle of the lengthened fender mounting bracket, it becomes difficult to secure the hand-push rigidity of the fender mounting bracket during normal use. If the fender mounting bracket is changed to a high-strength material or the plate thickness is increased in order to secure the hand-push rigidity, it becomes difficult to buckle.

本発明は、上記に鑑み、通常使用時は手押し剛性を確保しつつ、大きな荷重がかかったときは安定して座屈するフェンダ取付ブラケットを備えた車両側部構造の提供を目的とする。 In view of the above, an object of the present invention is to provide a vehicle side structure provided with a fender mounting bracket that stably buckles when a large load is applied while ensuring hand-push rigidity during normal use.

本発明の車両側部構造は、エンジンルームの側部を構成するエプロンメンバ上に、車両上方に向かって延設されたフェンダ取付ブラケットが設けられ、フェンダ取付ブラケットの基部に、補強部材が取り付けられ、フェンダ取付ブラケットの基部とエプロンメンバの上面と補強部材とによってボックスが形成され、ボックス直上に位置するフェンダ取付ブラケット上に剛性断点が設けられる。 In the vehicle side structure of the present invention, a fender mounting bracket extending toward the upper side of the vehicle is provided on the apron member constituting the side portion of the engine room, and a reinforcing member is mounted on the base of the fender mounting bracket. A box is formed by the base of the fender mounting bracket, the upper surface of the apron member, and the reinforcing member, and a rigid break point is provided on the fender mounting bracket located directly above the box.

ボックスを形成することにより、フェンダ取付ブラケットの基部の剛性が大となる。剛性断点は補強部材によって形成されるボックスの直上に位置する。フェンダ取付ブラケットの基部とその上側の部位との剛性差が大きくなり、剛性断点でフェンダ取付ブラケットは座屈しやすくなる。これにより、フェンダ取付ブラケットの剛性を小さくしなくても、座屈させることができるので、フェンダ取付ブラケットの手押し剛性を維持することができる。 By forming the box, the rigidity of the base of the fender mounting bracket is increased. The stiffness break is located directly above the box formed by the reinforcing member. The difference in rigidity between the base of the fender mounting bracket and the portion above it becomes large, and the fender mounting bracket tends to buckle at the rigidity break point. As a result, buckling can be performed without reducing the rigidity of the fender mounting bracket, so that the hand-pushing rigidity of the fender mounting bracket can be maintained.

本発明によると、ボックスを設けて、フェンダ取付ブラケットの基部の剛性を大きくすることにより、通常使用時の手押し剛性を確保しながら、大きな荷重がかかったときにフェンダ取付ブラケットを確実に座屈させて、衝撃を吸収することができる。 According to the present invention, by providing a box to increase the rigidity of the base of the fender mounting bracket, the fender mounting bracket is surely buckled when a large load is applied while ensuring the hand-pushing rigidity during normal use. And can absorb the impact.

本発明の実施形態に係る車両側部構造を図１、２に示す。本車両側部構造では、エンジンルーム１を覆うフード２の下方に、車両構造部材としてのエプロンメンバ３が車両前後方向に延設され、エンジンルーム１の側方にフェンダパネル４が設けられる。そして、フェンダパネル４を下方から支持するフェンダ取付ブラケット５がエプロンメンバ３の上側に車両上方に向かって延設される。 The vehicle side structure according to the embodiment of the present invention is shown in FIGS. 1 and 2. In the vehicle side structure, an apron member 3 as a vehicle structural member is extended in the vehicle front-rear direction below the hood 2 that covers the engine room 1, and a fender panel 4 is provided on the side of the engine room 1. Then, the fender mounting bracket 5 that supports the fender panel 4 from below is extended above the apron member 3 toward the upper side of the vehicle.

エプロンメンバ３は、断面ハット状に形成されたアウタ部材１０と縦壁状に形成されたインナ部材１１とが接合されて、断面台形状の閉空間が形成される。フェンダパネル４の上部は車幅方向内側に向かって折り曲げられたフランジ部１４が形成される。 In the apron member 3, the outer member 10 formed in the shape of a hat in cross section and the inner member 11 formed in the shape of a vertical wall are joined to form a closed space having a trapezoidal cross section. A flange portion 14 bent inward in the vehicle width direction is formed on the upper portion of the fender panel 4.

フェンダ取付ブラケット５は、エプロンメンバ３に取り付けられる基部１５とフェンダパネル４を支持する支持部１６とから構成される。基部１５は縦壁状に形成され、基部１５の下端側がエプロンメンバ３の外側面部１７に接合され、基部１５の上端側は、車両外側側に折り曲げられ、基部１５のほぼ中央に作業孔１８が形成される。 The fender mounting bracket 5 is composed of a base portion 15 mounted on the apron member 3 and a support portion 16 for supporting the fender panel 4. The base 15 is formed in a vertical wall shape, the lower end side of the base 15 is joined to the outer surface portion 17 of the apron member 3, the upper end side of the base 15 is bent toward the outer side of the vehicle, and the work hole 18 is substantially in the center of the base 15. It is formed.

フェンダ取付ブラケット５の支持部１６は、基部１５の上端からフード２に向かって連続的に縦壁状に形成され、基部１５よりも車幅方向内側に位置し、支持部１６の上端にフェンダパネル４のフランジ部１４の下面に当接する上面部１９が形成され、上面部１９とフランジ部１４とがボルト２０とナット２１とにより固定される。 The support portion 16 of the flanger mounting bracket 5 is continuously formed in a vertical wall shape from the upper end of the base portion 15 toward the hood 2, is located inside the base portion 15 in the vehicle width direction, and has a fender panel at the upper end of the support portion 16. An upper surface portion 19 that abuts on the lower surface of the flange portion 14 of 4 is formed, and the upper surface portion 19 and the flange portion 14 are fixed by the bolt 20 and the nut 21.

フェンダ取付ブラケット５の基部１５に補強部材が設けられる。補強部材としてロッド２２を回動可能に支持するフードサポートロッド取付ブラケット２３が基部１５の車幅方向内側に取り付けられる。フードサポートロッド取付ブラケット２３は、前面部２４、内側面部２５および上面部２６を有し、後面、外側面および下面が開口している。フードサポートロッド取付ブラケット２３の内側面部２５はフェンダ取付ブラケット５の基部１５に対向し、上面部２６から上方に向かって突設された上フランジ部２７が基部１５の上端に接合され、前面部２４から外側に向かって突設された前フランジ部２８が基部１５の前面に接合され、フードサポートロッド取付ブラケット２３の内側面部２５の下部がエプロンメンバ３の上縁部１２に接合される。 A reinforcing member is provided on the base 15 of the fender mounting bracket 5. A hood support rod mounting bracket 23 that rotatably supports the rod 22 as a reinforcing member is mounted inside the base 15 in the vehicle width direction. The hood support rod mounting bracket 23 has a front surface portion 24, an inner side surface portion 25, and an upper surface portion 26, and the rear surface, the outer surface portion, and the lower surface portion are open. The inner side surface portion 25 of the hood support rod mounting bracket 23 faces the base portion 15 of the fender mounting bracket 5, and the upper flange portion 27 projecting upward from the upper surface portion 26 is joined to the upper end of the base portion 15 and the front surface portion 24. The front flange portion 28 projecting outward from the side is joined to the front surface of the base portion 15, and the lower portion of the inner side surface portion 25 of the hood support rod mounting bracket 23 is joined to the upper edge portion 12 of the apron member 3.

フェンダ取付ブラケット５の基部１５、エプロンメンバ３の上面部３０およびフードサポートロッド取付ブラケット２３によって矩形状のボックス断面を有するボックス３１が形成される。ボックス３１は、後面を除く５面によって囲まれる。ボックス３１を設けることにより、基部１５の剛性が大となる。これにより、フードサポートロッド取付ブラケット２３において、ロッド２２の建て付け剛性が大きくなる。 The base portion 15 of the fender mounting bracket 5, the upper surface portion 30 of the apron member 3, and the hood support rod mounting bracket 23 form a box 31 having a rectangular box cross section. The box 31 is surrounded by five surfaces excluding the rear surface. By providing the box 31, the rigidity of the base 15 is increased. As a result, in the hood support rod mounting bracket 23, the built-in rigidity of the rod 22 is increased.

支持部１６の下端に、クランク部３２が設けられ、クランク部３２は上側の屈曲点３３と下側の屈曲点３４が車幅方向外側に向かう下り傾斜面３５により接続されることにより形成される。クランク部３２は、ボックス３１を構成するフードサポートロッド取付ブラケット２３の直上に位置する。 A crank portion 32 is provided at the lower end of the support portion 16, and the crank portion 32 is formed by connecting an upper bending point 33 and a lower bending point 34 by a downward inclined surface 35 toward the outside in the vehicle width direction. .. The crank portion 32 is located directly above the hood support rod mounting bracket 23 constituting the box 31.

クランク部３２を有する支持部１６の剛性は基部１５の剛性よりも小さいが、支持部１６の剛性は、手押しによる荷重がかかっても、変形しない程度の剛性を有する。なお、この手押し剛性は、クランク部３２の長さ、曲げ角度などの形態によって調整することができ、これにより、通常使用時の手押し剛性を確保することができる。 The rigidity of the support portion 16 having the crank portion 32 is smaller than the rigidity of the base portion 15, but the rigidity of the support portion 16 is such that it does not deform even when a load is applied by hand pushing. The hand-pushing rigidity can be adjusted according to the length of the crank portion 32, the bending angle, and the like, whereby the hand-pushing rigidity during normal use can be ensured.

クランク部３２は、脆弱部ではなく、フェンダ取付ブラケット５を折れやすくするための剛性断点であり、基部１５と支持部１６との大きな剛性差を利用して、効果的に剛性断点でフェンダ取付ブラケット５を座屈させることができる。 The crank portion 32 is not a fragile portion but a rigidity break point for making the fender mounting bracket 5 easy to break, and the fender is effectively broken at the rigidity break point by utilizing the large rigidity difference between the base portion 15 and the support portion 16. The mounting bracket 5 can be buckled.

上方から物体が衝突する等、一定値以上の荷重がかかると、図３に示すように、フード２が押しつぶされ、フェンダ取付ブラケット５に荷重がかかり、上側の屈曲点３３を起点にして、支持部１６が車幅方向外側に向かって倒れ、フェンダ取付ブラケット５はクランク部３２で座屈することにより、衝撃を吸収することができる。 When a load exceeding a certain value is applied, such as when an object collides from above, the hood 2 is crushed, the load is applied to the fender mounting bracket 5, and the fender mounting bracket 5 is supported from the upper bending point 33 as a starting point. The fender mounting bracket 5 can absorb the impact by tilting the portion 16 toward the outside in the vehicle width direction and buckling the fender mounting bracket 5 at the crank portion 32.

フェンダ取付ブラケット５が座屈すると、フード２が大きく変形して、フード２に当たった物体が下がってくる。このとき、物体がボックス３１の上面、すなわちフードサポートロッド取付ブラケット２３の上面部２６に届かないように、ボックス３１の上面の高さが設定されている。 When the fender mounting bracket 5 buckles, the hood 2 is greatly deformed, and the object that hits the hood 2 is lowered. At this time, the height of the upper surface of the box 31 is set so that the object does not reach the upper surface of the box 31, that is, the upper surface portion 26 of the hood support rod mounting bracket 23.

このように、フェンダ取付ブラケット５の基部１５を強くして座屈させる構造にすることにより、通常使用時の手押し剛性を確保でき、車両の意匠上フード２の位置が高くなって、フェンダ取付ブラケット５が長くなっても、手押し剛性と座屈を両立させることができる。 In this way, by making the base 15 of the fender mounting bracket 5 strong and buckling, it is possible to secure the hand-pushing rigidity during normal use, the position of the hood 2 is raised due to the design of the vehicle, and the fender mounting bracket is used. Even if 5 becomes long, it is possible to achieve both hand-push rigidity and buckling.

なお、本発明は、上記実施形態に限定されるものではなく、本発明の範囲内で上記実施形態に多くの修正および変更を加え得ることは勿論である。６面が塞がれたボックス３１にしてもよい。ボックス３１は完全な閉空間となり、剛性をさらに上げることができる。また、フェンダ取付ブラケット５をエプロンメンバ３の内側面部に設けてもよい。剛性断点として、クランク部３２の代わりに、フェンダ取付ブラケット５に貫通孔あるいは切欠きを形成してもよい。 It should be noted that the present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. A box 31 with six sides closed may be used. The box 31 becomes a completely closed space, and the rigidity can be further increased. Further, the fender mounting bracket 5 may be provided on the inner side surface portion of the apron member 3. As a rigidity break point, a through hole or a notch may be formed in the fender mounting bracket 5 instead of the crank portion 32.
