Description

本発明は、バンパビームの車両前方側に位置する貫通口が設けられたバンパパネルと、当該貫通口を覆うグリルとを備える、車両のフロントバンパにおけるバンパ構造に関する。   The present invention relates to a bumper structure in a front bumper of a vehicle, which includes a bumper panel provided with a through hole located on the front side of the bumper beam and a grill covering the through hole.

特許文献１には、車両のフロントバンパにおけるバンパ構造の一例が開示されている。当該バンパ構造は、バンパビーム（バンパリインフォース）の車両前方側に位置する貫通口（グリル開口）が設けられたバンパパネル（フロントバンパ外装部）と、バンパパネルに支持され、かつ貫通口を覆うグリル（メッシュグリル）とを備える。バンパパネルは、貫通口の左右両縁につながり、かつ貫通口を横断する横断部材を有する。横断部材は、バンパビームの車両前方側に位置し、かつグリルを支持している。   Patent Document 1 discloses an example of a bumper structure in a front bumper of a vehicle. The bumper structure includes a bumper panel (front bumper exterior) provided with a through-hole (grill opening) located on the vehicle front side of the bumper beam (bumper reinforcement), and a grill (mesh grill) supported by the bumper panel and covering the through-hole. ). The bumper panel includes cross members that are connected to the left and right edges of the through hole and that cross the through hole. The cross member is located on the vehicle front side of the bumper beam and supports the grill.

当該バンパ構造によれば、車両衝突により歩行者の脚部がグリルに接触したとき、グリルを介して横断部材がバンパビームに向けて弾性変形することにより、脚部への衝撃力を緩和するという効果が得られる。しかし、グリルは、剛性が比較的高い単一部材であるため、横断部材よりも弾性変形し難い。このため、軽衝突など、グリルが横断部材に向けてほとんど弾性変形しない場合は、脚部への衝撃力を緩和することが困難になるという課題がある。   According to the bumper structure, when the leg of the pedestrian comes into contact with the grill due to a vehicle collision, the cross member is elastically deformed toward the bumper beam through the grill, thereby reducing the impact force on the leg. Is obtained. However, since the grill is a single member having relatively high rigidity, it is less likely to be elastically deformed than the cross member. For this reason, when the grill hardly undergoes elastic deformation toward the cross member, such as a light collision, there is a problem that it is difficult to mitigate the impact force on the legs.

図１〜図３に示すように、横断部材２５は、上部材２２よりも車両下方に位置し、かつ車幅方向に延びている。横断部材２５は、貫通口２１の左右両縁につながっている。横断部材２５は、車両前後方向においてビームカバー３０とバンパビーム１１との間に位置する。これにより、車両前方から視たとき、バンパビーム１１は横断部材２５に重なっている。   As shown in FIGS. 1 to 3, the cross member 25 is positioned below the upper member 22 in the vehicle and extends in the vehicle width direction. The transverse member 25 is connected to the left and right edges of the through hole 21. The transverse member 25 is located between the beam cover 30 and the bumper beam 11 in the vehicle longitudinal direction. Thereby, the bumper beam 11 overlaps the cross member 25 when viewed from the front of the vehicle.

図１および図２に示すように、縦断部材２６は、バンパパネル２０の略中央に位置し、かつ車両上下方向に延びている。縦断部材２６は、上部材２２の下端と、横断部材２５の上端とにつながっている。なお、バンパパネル２０においては、縦断部材２６を設けない構成としてもよい。   As shown in FIGS. 1 and 2, the longitudinal member 26 is located substantially at the center of the bumper panel 20 and extends in the vehicle vertical direction. The longitudinal member 26 is connected to the lower end of the upper member 22 and the upper end of the cross member 25.

The beam cover 30 extends in the vehicle width direction. The beam cover 30 is supported by the cross member 25 and covers the beam cover 30 from the front of the vehicle. The beam cover 30 is made of synthetic resin.

上部グリル４０は、図１〜図３に示すように、車体構成部材１０に支持されている。上部グリル４０は、バンパパネル２０の上部材２２を支持し、かつ車両前方から上部材２２を覆っている。上部グリル４０は、バンパパネル２０の貫通口２１のうち、ビームカバー３０よりも車両上方に位置する領域を覆っている。上部グリル４０が、本発明にかかる特許請求の範囲に記載の「グリル」に相当する。上部グリル４０は、合成樹脂製である。上部グリル４０は、車両後方に向けて車両走行風が通り抜ける構成となっている。上部グリル４０は、支持部４１および複数の支持片４２を有する。   As shown in FIGS. 1 to 3, the upper grill 40 is supported by the vehicle body constituting member 10. The upper grill 40 supports the upper member 22 of the bumper panel 20 and covers the upper member 22 from the front of the vehicle. The upper grill 40 covers an area of the through hole 21 of the bumper panel 20 that is located above the beam cover 30 in the vehicle. The upper grill 40 corresponds to the “grill” described in the claims of the present invention. The upper grill 40 is made of synthetic resin. The upper grill 40 is configured such that vehicle traveling wind passes through the rear of the vehicle. The upper grill 40 has a support portion 41 and a plurality of support pieces 42.

図１および図３に示すように、支持部４１は、上部材２２よりも車両上方に位置し、かつ上部グリル４０の上端から車両後方に向けて延びている。支持部４１には、車両上下方向に貫通する複数の支持孔４１１が設けられている。一方、車体構成部材１０には、車両上下方向に貫通する複数の取付け孔１０１が設けられている。複数の取付け孔１０１の位置は、複数の支持孔４１１の位置に対応している。複数の取付け孔１０１の車両上方に複数の支持孔４１１が位置するように支持部４１を車体構成部材１０に配置した後、複数の支持孔４１１および複数の取付け孔１０１に対して、複数の締結部材４９を個別に挿入させる。複数の締結部材４９は、たとえば合成樹脂製のピンである。これにより、支持部４１は、車体構成部材１０に支持される。したがって、上部グリル４０は、車体構成部材１０に支持される構成をなす。   As shown in FIGS. 1 and 3, the support portion 41 is located above the upper member 22 and extends from the upper end of the upper grill 40 toward the rear of the vehicle. The support part 41 is provided with a plurality of support holes 411 penetrating in the vehicle vertical direction. On the other hand, the vehicle body constituting member 10 is provided with a plurality of mounting holes 101 penetrating in the vehicle vertical direction. The positions of the plurality of attachment holes 101 correspond to the positions of the plurality of support holes 411. After arranging the support portion 41 in the vehicle body constituting member 10 so that the plurality of support holes 411 are positioned above the plurality of attachment holes 101 in the vehicle, a plurality of fastenings are performed with respect to the plurality of support holes 411 and the plurality of attachment holes 101. The members 49 are inserted individually. The plurality of fastening members 49 are, for example, synthetic resin pins. Thereby, the support part 41 is supported by the vehicle body structural member 10. Therefore, the upper grill 40 is configured to be supported by the vehicle body constituent member 10.

図２および図３に示すように、複数の支持片４２は、車両後方に向けて突出し、かつ上部材２２に設けられた複数の支持孔２２１に対応して設けられている。複数の支持片４２を、複数の支持孔２２１に挿入させる。これにより、上部材２２は、上部グリル４０に支持される。したがって、バンパパネル２０は、上部グリル４０に支持される構成をなす。   As shown in FIG. 2 and FIG. 3, the plurality of support pieces 42 protrude toward the rear of the vehicle and are provided corresponding to the plurality of support holes 221 provided in the upper member 22. The plurality of support pieces 42 are inserted into the plurality of support holes 221. As a result, the upper member 22 is supported by the upper grill 40. Therefore, the bumper panel 20 is configured to be supported by the upper grill 40.

図３に示すように、ビームカバー３０の上端３０Ａおよび上部グリル４０の下端４０Ａは、互いに離間している。   As shown in FIG. 3, the upper end 30A of the beam cover 30 and the lower end 40A of the upper grill 40 are separated from each other.

下部グリル５０は、図１〜図３に示すように、バンパパネル２０に支持されている。下部グリル５０の上端は、バンパパネル２０の横断部材２５に支持されている。下部グリル５０の下端は、バンパパネル２０の下部材２３に支持されている。下部グリル５０は、バンパパネル２０の貫通口２１のうち、ビームカバー３０よりも車両下方に位置する領域を覆っている。下部グリル５０は、合成樹脂製である。下部グリル５０は、車両後方に向けて車両走行風が通り抜ける構成となっている。   The lower grill 50 is supported by the bumper panel 20 as shown in FIGS. The upper end of the lower grill 50 is supported by the transverse member 25 of the bumper panel 20. The lower end of the lower grill 50 is supported by the lower member 23 of the bumper panel 20. The lower grill 50 covers an area of the through hole 21 of the bumper panel 20 that is located below the beam cover 30 in the vehicle. The lower grill 50 is made of synthetic resin. The lower grill 50 is configured such that vehicle travel wind passes through the rear of the vehicle.

次に、バンパ構造Ａの作用効果について説明する。   Next, the effect of the bumper structure A will be described.

バンパ構造Ａでは、バンパビーム１１、バンパパネル２０、ビームカバー３０および上部グリル４０を備える。バンパパネル２０は、上部材２２において上部グリル４０により支持されている。ビームカバー３０は、バンパパネル２０に支持され、かつバンパビーム１１の車両前方側に位置する。上部グリル４０は、支持部４１により車体構成部材１０に支持されている。支持部４１は、上部材２２よりも車両上方に位置し、かつ上部グリル４０の上端から車両後方に延びている。ビームカバー３０の上端３０Ａおよび上部グリル４０の下端４０Ａは、互いに離間している。これにより、図４に示すように、車両衝突において歩行者の脚部６０がバンパ構造Ａに接触した際、ビームカバー３０はバンパビーム１１に向けて弾性変形する。上部グリル４０は、支持部４１を支点として車幅方向回りに弾性変形することにより、車両後方に傾斜する。よって、ビームカバー３０および上部グリル４０の双方が車両後方に向けてたわむことにより衝撃エネルギーが吸収されるため、バンパ構造Ａから脚部６０に作用する衝撃力を緩和することができる。したがって、バンパ構造Ａによれば、車両衝突の際、歩行者をより適切に保護することが可能となる。   The bumper structure A includes a bumper beam 11, a bumper panel 20, a beam cover 30 and an upper grill 40. The bumper panel 20 is supported by the upper grill 40 on the upper member 22. The beam cover 30 is supported by the bumper panel 20 and is located on the vehicle front side of the bumper beam 11. The upper grill 40 is supported by the vehicle body constituting member 10 by a support portion 41. The support portion 41 is located above the upper member 22 in the vehicle and extends rearward from the upper end of the upper grill 40. The upper end 30A of the beam cover 30 and the lower end 40A of the upper grill 40 are separated from each other. As a result, as shown in FIG. 4, when the pedestrian's leg 60 contacts the bumper structure A in a vehicle collision, the beam cover 30 is elastically deformed toward the bumper beam 11. The upper grille 40 is inclined rearward of the vehicle by elastically deforming around the vehicle width direction with the support portion 41 as a fulcrum. Therefore, since both the beam cover 30 and the upper grille 40 bend toward the rear of the vehicle, the impact energy is absorbed, so that the impact force acting on the leg portion 60 from the bumper structure A can be reduced. Therefore, according to the bumper structure A, a pedestrian can be more appropriately protected in the event of a vehicle collision.

バンパパネル２０は、上部材２２よりも車両下方に位置し、かつ貫通口２１の左右両縁につながる横断部材２５を有する。横断部材２５は、車両前後方向においてビームカバー３０とバンパビーム１１との間に位置する。ビームカバー３０は、横断部材２５に支持されている。これにより、図４に示すように、車両衝突において歩行者の脚部６０がバンパ構造Ａに接触した際、横断部材２５は、ビームカバー３０と一体となってバンパビーム１１に向けて弾性変形する。横断部材２５は、バンパビーム１１に接触する。これにより、横断部材２５およびバンパビーム１１の双方により衝撃エネルギーがさらに吸収されるため、バンパ構造Ａから脚部６０に作用する衝撃力をさらに緩和することができる。したがって、歩行者の保護効果をより向上させることができる。   The bumper panel 20 includes a transverse member 25 that is located below the upper member 22 and connected to the left and right edges of the through hole 21. The transverse member 25 is located between the beam cover 30 and the bumper beam 11 in the vehicle longitudinal direction. The beam cover 30 is supported by the cross member 25. As a result, as shown in FIG. 4, when the pedestrian leg 60 contacts the bumper structure A in a vehicle collision, the cross member 25 is elastically deformed toward the bumper beam 11 together with the beam cover 30. The transverse member 25 contacts the bumper beam 11. Thereby, since the impact energy is further absorbed by both the transverse member 25 and the bumper beam 11, the impact force acting on the leg portion 60 from the bumper structure A can be further alleviated. Therefore, the pedestrian protection effect can be further improved.

本発明は、先述した実施形態に限定されるものではない。本発明の各部の具体的な構成は、種々に設計変更自在である。   The present invention is not limited to the embodiment described above. The specific configuration of each part of the present invention can be changed in various ways.
