Japanese Patent Application Laid-Open No. 2002-264741

特許文献１に記載された連結部材としての下部衝撃吸収部材は、車両前後方向に延在するビードが車幅方向に複数並べられて構成されている。そして、これらのビードは、その前端開口がリブによって閉塞され、その後端部がクロスメンバに固定されている。このため、この下部吸収部材は、入力荷重の車両幅方向への伝達性が悪く、入力荷重の吸収効率が悪いという問題がある。   The lower impact absorbing member as a connecting member described in Patent Document 1 is configured by arranging a plurality of beads extending in the vehicle front-rear direction in the vehicle width direction. These beads have their front end openings closed by ribs and their rear ends fixed to the cross member. For this reason, this lower absorption member has a problem that input load in the vehicle width direction is poor and input load absorption efficiency is poor.

そこで、本発明は、車両用バンパ構造において、入力荷重を効率的に吸収できるようにすること目的とする。   Accordingly, an object of the present invention is to enable an input load to be efficiently absorbed in a vehicle bumper structure.

本発明は、バンパカバーとこのバンパカバーの車両内方に配設された骨格部材とを連結すると共に入力荷重を吸収する連結部材を備え、この連結部材に車両前後方向に沿った複数のビードが車幅方向に間隔をあけて突設された車両用バンパ構造であって、前記ビードは、前記バンパカバー側の端部が開口されると共に左右一対の側壁の突出基部間が開口されており、前記連結部材は、前記バンパカバー側から荷重が入力された場合、前記ビードの左右一対の前記側壁における突出基部間の車幅方向距離が変化するように変形することを最も主要な特徴とする。   The present invention includes a connecting member that connects a bumper cover and a skeleton member disposed inside the vehicle of the bumper cover and absorbs an input load, and the connecting member includes a plurality of beads along the vehicle front-rear direction. A bumper structure for a vehicle projecting at an interval in the vehicle width direction, wherein the bead has an end on the bumper cover side and an opening between the protruding bases of a pair of left and right side walls, The connecting member is most characterized in that, when a load is input from the bumper cover side, the connecting member is deformed so that the distance in the vehicle width direction between the protruding bases of the pair of left and right side walls of the bead changes.

本発明によれば、連結部材が、バンパカバー側からの入力荷重によって、ビードの左右一対の側壁における突出基部間距離が変化するように変形することにより、入力荷重を車幅方向で分散して吸収することができるので、入力荷重を効率的に吸収できる。   According to the present invention, the connecting member is deformed so that the distance between the protruding bases on the pair of left and right side walls of the bead is changed by the input load from the bumper cover side, so that the input load is dispersed in the vehicle width direction. Since it can absorb, input load can be absorbed efficiently.

詳しくは、ビード１４のうち、その後方に後メンバ部１３の縦壁１３ａに形成された取付孔１３ｃが位置していないビード１４は、後方斜め下方に向けて傾斜した後壁１４ｆによって閉塞されている。この後壁１４ｆは、左右一対の縦リブ１７を介して後メンバ部１３の縦壁１３ａに連結されている。一方、ビード１４のうち、その後方に後メンバ部１３の縦壁１３ａの取付孔１３ｃが位置しているビード１４は、その後壁１４ｆの一部に切欠が形成されている。そして、この切欠の縁部が、下方に開口した断面コ字状のリブ１８によって後メンバ部１３の縦壁１３ａに連結されており、この構造によって、ビード１４の後端部１４ｅが閉塞されている。また、このように、切欠及びリブを設けることによって、メンバ部へのクリップ１５の取付作業空間が確保されている。そして、縦リブ１７、リブ１８及び後メンバ部１３によって、ビード１４から連結部材５へ力を車両前後方向に沿って伝達する伝達構造が構成されている。   Specifically, in the bead 14, the bead 14 in which the mounting hole 13c formed in the vertical wall 13a of the rear member portion 13 is not located behind is blocked by a rear wall 14f inclined obliquely downward and rearward. Yes. The rear wall 14 f is connected to the vertical wall 13 a of the rear member portion 13 via a pair of left and right vertical ribs 17. On the other hand, the bead 14 in which the mounting hole 13c of the vertical wall 13a of the rear member part 13 is located behind the bead 14 has a notch formed in a part of the rear wall 14f. The edge of the notch is connected to the vertical wall 13a of the rear member 13 by a rib 18 having a U-shaped cross section that opens downward. With this structure, the rear end 14e of the bead 14 is closed. Yes. Further, by providing the notches and ribs in this way, a work space for attaching the clip 15 to the member portion is secured. The vertical rib 17, the rib 18, and the rear member portion 13 constitute a transmission structure that transmits force from the bead 14 to the connecting member 5 along the vehicle front-rear direction.

また、隣合うビード１４同士は、それらのバンパカバー１側の端部間を第１のリブ部１２によって連結されている。また、隣合うビード１４間には、第１のリブ部１２よりも後方の位置で第２のリブ部１９が架設されている。第２のリブ部１９は、凹部と凸部とが車両前後方向で交互に繰り返された蛇腹形状をなしている。この第２のリブ部１９は、車両前後方向において、ロアメンバ４と、上部衝撃吸収部材３におけるバンパレインフォースメント２に対する固定部分との間に配置されている（図１）。   Adjacent beads 14 are connected by the first rib portion 12 between the ends on the bumper cover 1 side. Further, a second rib portion 19 is installed between the adjacent beads 14 at a position behind the first rib portion 12. The second rib portion 19 has a bellows shape in which concave portions and convex portions are alternately repeated in the vehicle front-rear direction. The second rib portion 19 is disposed between the lower member 4 and a fixed portion of the upper impact absorbing member 3 with respect to the bumper reinforcement 2 in the vehicle longitudinal direction (FIG. 1).

また、連結部材５の前部には、バンパカバー１が固定されるカバー取付部２０が形成されている。具体的には、連結部材５の前部における各ビード１４間を連結している部分に、バンパカバー１の取付面９に上から重なるカバー取付面２０ａが形成されている。そして、このカバー取付面２０ａにバンパカバー１の取付面９がクリップ１５によって締結されることにより、連結部材５にバンパカバー１が固定される。   Further, a cover attachment portion 20 to which the bumper cover 1 is fixed is formed at the front portion of the connecting member 5. Specifically, a cover mounting surface 20 a that overlaps the mounting surface 9 of the bumper cover 1 from above is formed at a portion connecting the beads 14 at the front portion of the connecting member 5. The bumper cover 1 is fixed to the connecting member 5 by fastening the attachment surface 9 of the bumper cover 1 to the cover attachment surface 20 a with the clip 15.

このような構成において、車両が障害物に前面衝突し、上部衝撃吸収部材３と連結部材５とにバンパカバー１側から荷重が局部的に入力された場合、それら上部衝撃吸収部材３と連結部材５とは、それぞれ車両前後方向に潰れ変形して、入力荷重を吸収する。このとき、連結部材５では、ビード１４の左右一対の側壁１４ｂの突出基部１４ｃ間距離が変化するように変形する。詳しくは、前端部１４ｄから荷重が入力されビード１４が、左右一対の側壁１４ｂの突出基部１４ｃ間距離が広がるように変形すると共に、連結部材５において隣合うビード１４間を連結している部分がその両側に位置する側壁１４ｂに押されて車両幅方向に潰れ変形する。したがって、入力荷重を車幅方向で分散して吸収することができるので、入力荷重を効率的に吸収できる。   In such a configuration, when the vehicle collides front with an obstacle and a load is locally input to the upper impact absorbing member 3 and the connecting member 5 from the bumper cover 1 side, the upper impact absorbing member 3 and the connecting member. 5 is each crushed and deformed in the longitudinal direction of the vehicle to absorb the input load. At this time, the connecting member 5 is deformed so that the distance between the protruding base portions 14c of the pair of left and right side walls 14b of the bead 14 changes. Specifically, when a load is input from the front end portion 14d, the bead 14 is deformed so that the distance between the protruding base portions 14c of the pair of left and right side walls 14b is widened, and a portion connecting the adjacent beads 14 in the connecting member 5 is formed. It is pushed by the side wall 14b located on both sides and is crushed and deformed in the vehicle width direction. Therefore, since the input load can be dispersed and absorbed in the vehicle width direction, the input load can be absorbed efficiently.

ここで、本実施の形態の上部衝撃吸収部材３と連結部材５との衝撃吸収特性グラフを図６に示す。グラフの縦軸は吸収エネルギー量Ｆ、横軸は車両前後方向での潰れ量Ｓを示している。図６に示すように、上部衝撃吸収部材３と連結部材５との衝撃吸収は、衝突初期段階において、より多くなされている。ここで、連結部材５は、第１のリブ部１２によって、衝突初期段階における吸収荷重量の増大化が図られている。   Here, FIG. 6 shows an impact absorption characteristic graph of the upper impact absorbing member 3 and the connecting member 5 of the present embodiment. The vertical axis of the graph indicates the amount of absorbed energy F, and the horizontal axis indicates the amount of collapse S in the vehicle front-rear direction. As shown in FIG. 6, the upper shock absorbing member 3 and the connecting member 5 absorb more shock at the initial stage of the collision. Here, the connection member 5 is designed to increase the amount of absorbed load at the initial stage of the collision by the first rib portion 12.

また、本実施の形態においては、上部衝撃吸収部材３の前端位置と連結部材５の前端位置とが略同じであることにより、障害物への反力を上部衝撃吸収部材３と連結部材５とで略同じにすることができる。   In the present embodiment, since the front end position of the upper impact absorbing member 3 and the front end position of the connecting member 5 are substantially the same, the reaction force against the obstacle is increased between the upper impact absorbing member 3 and the connecting member 5. Can be made substantially the same.

また、本実施の形態においては、隣合うビード１４間に第２のリブ部が架設されていることにより、上部衝撃吸収部材３のバンパレインフォースメント２に対する固定部分よりも後方となるビード１４の部分の変形を抑制することができ、よって、連結部材５の変形領域を上部衝撃吸収部材の変形領域に合わせることができる。   Further, in the present embodiment, since the second rib portion is installed between the adjacent beads 14, the bead 14 located behind the fixed portion of the upper impact absorbing member 3 with respect to the bumper reinforcement 2 is arranged. The deformation of the portion can be suppressed, so that the deformation region of the connecting member 5 can be matched with the deformation region of the upper impact absorbing member.

また、本実施の形態においては、ビード１４から連結部材５へ力を車両前後方向に沿って伝達する伝達構造を備え、連結部材５は、車両前後方向及び車両上下方向でロアメンバ４に突き当て固定されていることにより、連結部材５に前面から荷重が入力された場合に、連結部材５がロアメンバ４側を支点として折れ曲がることを抑制することができる。   Further, in the present embodiment, a transmission structure that transmits force from the bead 14 to the connecting member 5 along the vehicle front-rear direction is provided, and the connecting member 5 abuts and is fixed to the lower member 4 in the vehicle front-rear direction and the vehicle vertical direction. Thus, when a load is input to the connecting member 5 from the front surface, the connecting member 5 can be prevented from being bent with the lower member 4 side as a fulcrum.

なお、本発明は、本実施形態に限ることなく本発明の要旨を逸脱しない範囲で他の実施形態を各種採用することができる。   The present invention is not limited to this embodiment, and various other embodiments can be adopted without departing from the gist of the present invention.
