［バンパーＳの周辺構成］
図１は、本実施形態に係るバンパーＳが車両に設けられている状態を示す図である。
車両は、サイドフレームＦ、及びバンパーＳを有する。サイドフレームＦは、車両の前後方向において延伸している部材である。サイドフレームＦは、例えば断面がコ字形状である。２本のサイドフレームＦが平行に設けられている。バンパーＳは、車両が外部の物体と衝突した際に、衝撃を和らげることで車体、乗員、及び外部の物体を保護するための部材である。バンパーＳは、例えば、車両のサイドフレームＦの前端又は後端に固定されている。図１に示すバンパーＳは、車両の前方に設けられている例を示しているが、バンパーＳは車両の後方に設けられていてもよい。 [Peripheral Configuration of Bumper S]
FIG. 1 is a diagram showing a state in which a bumper S according to this embodiment is provided on a vehicle.
The vehicle has a side frame F and a bumper S. The side frame F is a member extending in the longitudinal direction of the vehicle. The side frame F has, for example, a U-shaped cross section. Two side frames F are provided in parallel. The bumper S is a member for protecting the vehicle body, passengers, and external objects by softening the impact when the vehicle collides with an external object. The bumper S is fixed to, for example, the front end or the rear end of the side frame F of the vehicle. Although the bumper S shown in FIG. 1 is provided in front of the vehicle, the bumper S may be provided in the rear of the vehicle.

［バンパーＳの構造］
図２は、本実施形態に係るバンパーＳを構成する部材が分離された状態を示す図である。
バンパーＳは、外側部１、内側部２、及び補強部材３を有する。外側部１は、車両の車幅方向に延伸している部材である。具体的には、外側部１は、車両の前方に設けられているバンパーＳにおいて、最も前方側に設けられている部材である。外側部１は、内側部２及び補強部材３よりも変形しやすい。内側部２は、外側部１よりも車両の内側において、車両の車幅方向に延伸している部材である。車両の内側は、車両の中心により近い側である。具体的には、内側部２は、外側部１よりも車両の前後方向における後方において、車両の車幅方向に延伸している部材である。 [Structure of Bumper S]
FIG. 2 is a diagram showing a state in which the members constituting the bumper S according to this embodiment are separated.
The bumper S has an outer part 1 , an inner part 2 and a reinforcing member 3 . The outer portion 1 is a member extending in the width direction of the vehicle. Specifically, the outer portion 1 is a member provided on the frontmost side in a bumper S provided in front of the vehicle. The outer part 1 is more deformable than the inner part 2 and the reinforcing member 3 . The inner portion 2 is a member that extends in the vehicle width direction on the inner side of the vehicle than the outer portion 1 . The inside of the vehicle is the side closer to the center of the vehicle. Specifically, the inner portion 2 is a member extending in the width direction of the vehicle behind the outer portion 1 in the longitudinal direction of the vehicle.

内側部２は、脆弱領域２１を有する。脆弱領域２１は、内側部２における他の領域よりも変形しやすい領域であり、例えば、他の領域よりも薄く形成されている領域、又は開口が形成されている領域である。内側部２の詳細は後述する。 The inner part 2 has a weakened area 21 . The weakened region 21 is a region in the inner portion 2 that is more deformable than other regions, and is, for example, a region formed thinner than the other regions or a region in which an opening is formed. Details of the inner portion 2 will be described later.

補強部材３は、外側部１と内側部２との間に設けられている。具体的には、補強部材３は、外側部１と内側部２との車両の前後方向における間に設けられている。補強部材３は、突出部３１を有する。突出部３１は、脆弱領域２１よりも車両の車幅方向における外側において内側部２に向かって延伸している部位である。 A reinforcing member 3 is provided between the outer portion 1 and the inner portion 2 . Specifically, the reinforcing member 3 is provided between the outer portion 1 and the inner portion 2 in the front-rear direction of the vehicle. The reinforcing member 3 has a projecting portion 31 . The projecting portion 31 is a portion that extends toward the inner portion 2 on the outer side of the weakened region 21 in the vehicle width direction.

バンパーＳは、このような内側部２及び補強部材３を有することで、バンパーＳの長手方向における両側の端部付近に歩行者が衝突した場合、突出部３１が内側部２の脆弱領域２１よりも車両の車幅方向における外側の領域を後方に向かって押すため、脆弱領域２１が変形する。バンパーＳは、脆弱領域２１が変形することで、バンパーＳの長手方向における両側の端部付近が後方に向かって曲がりやすい。したがって、歩行者がバンパーＳに衝突した時点で車両が前方に進んでいる間、バンパーＳが、歩行者に接触した状態で斜め前方向に移動する。その結果、歩行者が、車両の車幅方向における外側に向かって回転しながら、車両の外側に向かって倒れやすくなる。 The bumper S has the inner portion 2 and the reinforcing member 3 as described above, so that when a pedestrian collides near both ends of the bumper S in the longitudinal direction, the protruding portion 31 is more likely than the weakened area 21 of the inner portion 2. also pushes the outer region of the vehicle in the vehicle width direction rearward, so the fragile region 21 is deformed. The bumper S tends to bend rearward in the vicinity of both ends in the longitudinal direction of the bumper S due to the deformation of the fragile region 21 . Therefore, while the vehicle is moving forward when the pedestrian collides with the bumper S, the bumper S moves obliquely forward in contact with the pedestrian. As a result, the pedestrian tends to fall toward the outside of the vehicle while rotating toward the outside of the vehicle in the vehicle width direction.

また、突出部３１の先端は、外側部１が車両の内側に向かって押されることで、内側部２の外側部１側の面における脆弱領域２１よりも車両の車幅方向における外側の領域に接する。具体的には、突出部３１の内側部２側の端部は、外側部１が車両の前後方向における後方に向かって押されることで、内側部２の前面における脆弱領域２１よりも車両の車幅方向における外側の領域に接する。 In addition, when the outer portion 1 is pushed toward the inside of the vehicle, the tip of the protruding portion 31 is positioned outside the weakened region 21 on the surface of the inner portion 2 facing the outer portion 1 in the vehicle width direction of the vehicle. touch. Specifically, when the outer portion 1 is pushed rearward in the longitudinal direction of the vehicle, the end portion of the protruding portion 31 on the inner portion 2 side is pushed further toward the vehicle than the fragile region 21 on the front surface of the inner portion 2 . Contact with the outer region in the width direction.

よって、バンパーＳは、バンパーＳが歩行者に衝突した場合、突出部３１の先端が、内側部２の外側部１側の面における脆弱領域２１よりも車両の車幅方向における外側の領域に接する。突出部３１の先端が、内側部２の脆弱領域２１よりも車両の外側の領域を後方に向かって押すので、脆弱領域２１を変形させることができる。その結果、バンパーＳの外側の領域が後方に曲がるように変形する。 Therefore, in the bumper S, when the bumper S collides with a pedestrian, the tip of the protruding portion 31 is in contact with the outer region in the vehicle width direction of the vehicle rather than the weakened region 21 on the surface of the inner portion 2 on the outer portion 1 side. . Since the tip of the projecting portion 31 pushes the area outside the vehicle rearward rather than the weakened area 21 of the inner portion 2, the weakened area 21 can be deformed. As a result, the outer region of the bumper S deforms so as to bend backward.

バンパーＳは、補強部材３として、第１補強部材３ａ、及び第２補強部材３ｂを有する。第１補強部材３ａは、外側部１の車両の車幅方向における一端と内側部２の車両の車幅方向における当該一端と同じ側の一端との間に設けられている補強部材である。具体的には、第１補強部材３ａは、外側部１の車両の車幅方向における左端と内側部２の車両の車幅方向における左端との間に設けられている補強部材である。 The bumper S has, as reinforcing members 3, a first reinforcing member 3a and a second reinforcing member 3b. The first reinforcing member 3a is a reinforcing member provided between one end of the outer portion 1 in the vehicle width direction and one end of the inner portion 2 on the same side as the one end in the vehicle width direction. Specifically, the first reinforcing member 3a is a reinforcing member provided between the left end of the outer portion 1 in the vehicle width direction and the left end of the inner portion 2 in the vehicle width direction.

第２補強部材３ｂは、外側部１の車両の車幅方向における他端と内側部２の車両の車幅方向における当該他端と同じ側の他端との間に設けられている補強部材である。具体的には、第２補強部材３ｂは、外側部１の車両の車幅方向における右端と内側部２の車両の車幅方向における右端との間に設けられている補強部材である。 The second reinforcing member 3b is a reinforcing member provided between the other end of the outer portion 1 in the vehicle width direction and the other end of the inner portion 2 on the same side as the other end in the vehicle width direction. be. Specifically, the second reinforcing member 3b is a reinforcing member provided between the right end of the outer portion 1 in the vehicle width direction and the right end of the inner portion 2 in the vehicle width direction.

内側部２は、脆弱領域２１として、第１脆弱領域２１ａ、及び第２脆弱領域２１ｂを有する。第１脆弱領域２１ａは、第１補強部材３ａよりも車両の内側に位置する脆弱領域である。具体的には、第１脆弱領域２１ａは、第１補強部材３ａよりも車両の後方に位置する脆弱領域である。第２脆弱領域２１ｂは、第２補強部材３ｂよりも車両の内側に位置する脆弱領域である。具体的には、第２脆弱領域２１ｂは、第２補強部材３ｂよりも車両の後方に位置する脆弱領域である。 The inner portion 2 has, as the weakened regions 21, a first weakened region 21a and a second weakened region 21b. The first weakened area 21a is a weakened area located inside the vehicle relative to the first reinforcing member 3a. Specifically, the first weakened area 21a is a weakened area located behind the first reinforcing member 3a in the vehicle. The second weakened area 21b is a weakened area located inside the vehicle relative to the second reinforcing member 3b. Specifically, the second weakened area 21b is a weakened area located behind the second reinforcing member 3b in the vehicle.

このように、バンパーＳは、車両の両側に補強部材３及び脆弱領域２１を有することで、歩行者が外側部１の長手方向における中央付近に衝突した場合に、外側部１が内側に向かって窪むように変形することで、歩行者に与える衝撃を小さくすることができる。 In this way, the bumper S has the reinforcing members 3 and the weakened areas 21 on both sides of the vehicle, so that when a pedestrian collides near the center in the longitudinal direction of the outer portion 1, the outer portion 1 moves inward. By deforming so as to be depressed, it is possible to reduce the impact on pedestrians.

内側部２は、例えば断面がコ字形状の領域を有する。内側部２は、外側板部２２、上面板部２３、下面板部２４、第１凹部２５、及び第２凹部２６を有する。外側板部２２は、外側部１側に設けられている部位である。上面板部２３は、外側板部２２の上端から車両の内側に向かって延伸している部位である。具体的には、上面板部２３は、外側板部２２の上端から車両の前後方向における後方に向かって延伸している部位である。 The inner portion 2 has, for example, a U-shaped cross section. The inner portion 2 has an outer plate portion 22 , an upper plate portion 23 , a lower plate portion 24 , a first concave portion 25 and a second concave portion 26 . The outer plate portion 22 is a portion provided on the outer portion 1 side. The upper plate portion 23 is a portion extending from the upper end of the outer plate portion 22 toward the inside of the vehicle. Specifically, the upper plate portion 23 is a portion that extends rearward in the front-rear direction of the vehicle from the upper end of the outer plate portion 22 .

下面板部２４は、外側板部２２の下端から車両の内側に向かって延伸している部位である。具体的には、下面板部２４は、外側板部２２の下端から車両の前後方向における後方に向かって延伸している部位である。 The lower surface plate portion 24 is a portion extending from the lower end of the outer plate portion 22 toward the inside of the vehicle. Specifically, the lower surface plate portion 24 is a portion extending rearward in the front-rear direction of the vehicle from the lower end of the outer plate portion 22 .

第１凹部２５は、上面板部２３の外側板部２２と接続されている側とは反対側の端部に形成されている凹部である。具体的には、第１凹部２５は、上面板部２３の後端に形成されている凹部である。 The first recessed portion 25 is a recessed portion formed at the end portion of the upper surface plate portion 23 opposite to the side connected to the outer plate portion 22 . Specifically, the first concave portion 25 is a concave portion formed at the rear end of the upper surface plate portion 23 .

Specifically, the second recess 26 is a recess formed at the rear end of the lower plate portion 24 .

脆弱領域２１は、第１凹部２５及び第２凹部２６を有する領域である。バンパーＳは、このような内側部２を有することで、部品点数を増加させずに、簡易に脆弱領域２１を設けることができる。 The weakened area 21 is an area having a first recess 25 and a second recess 26 . By having such an inner portion 2, the bumper S can easily provide the fragile region 21 without increasing the number of parts.

［変形例］
上記実施形態においては、バンパーＳは、車両の前後方向における前方に設けられている例を示したが、これに限定されない。バンパーＳは、車両の後方に設けられていてもよい。 [Modification]
In the above-described embodiment, the example in which the bumper S is provided in front of the vehicle in the front-rear direction is shown, but the present invention is not limited to this. The bumper S may be provided at the rear of the vehicle.

［本実施形態に係るバンパーＳによる効果］
本実施形態に係るバンパーＳは、車両の車幅方向に延伸している外側部１と、外側部１よりも車両の内側において、車両の車幅方向に延伸している内側部２であって、内側部２における他の領域よりも変形しやすい脆弱領域２１を有する内側部２と、を有する。また、バンパーＳは、外側部１と内側部２との間に設けられており、脆弱領域２１よりも車両の車幅方向における外側において内側部２に向かって延伸している突出部３１を有する補強部材３を有する。 [Effects of the bumper S according to the present embodiment]
The bumper S according to the present embodiment includes an outer portion 1 extending in the vehicle width direction of the vehicle and an inner portion 2 extending in the vehicle width direction on the inner side of the vehicle than the outer portion 1. , and an inner portion 2 having weakened areas 21 that are more susceptible to deformation than other areas of the inner portion 2 . The bumper S is provided between the outer portion 1 and the inner portion 2, and has a projecting portion 31 extending toward the inner portion 2 outside the weakened region 21 in the vehicle width direction. It has a reinforcing member 3 .

本実施形態に係るバンパーＳは、このような内側部２及び補強部材３を有することで、バンパーＳの長手方向における両側の端部付近に歩行者が衝突した場合、突出部３１が内側部２の脆弱領域２１よりも車両の車幅方向における外側の領域を後方に向かって押すため、脆弱領域２１が変形する。バンパーＳは、脆弱領域２１が変形することで、バンパーＳの長手方向における両側の端部付近が後方に向かって曲がりやすい。したがって、歩行者がバンパーＳに衝突した時点で車両が前方に進んでいる間、バンパーＳが、歩行者に接触した状態で斜め前方向に移動する。その結果、歩行者が、車両の車幅方向における外側に向かって回転しながら、車両の外側に向かって倒れやすくなる。 The bumper S according to the present embodiment includes the inner portion 2 and the reinforcing member 3 as described above, so that when a pedestrian collides near both ends in the longitudinal direction of the bumper S, the protruding portion 31 is removed from the inner portion 2. Since the area outside the fragile area 21 in the vehicle width direction of the vehicle is pushed rearward, the fragile area 21 is deformed. The bumper S tends to bend rearward in the vicinity of both ends in the longitudinal direction of the bumper S due to the deformation of the fragile region 21 . Therefore, while the vehicle is moving forward when the pedestrian collides with the bumper S, the bumper S moves obliquely forward in contact with the pedestrian. As a result, the pedestrian tends to fall toward the outside of the vehicle while rotating toward the outside of the vehicle in the vehicle width direction.

よって、車両の車幅方向の外側付近に歩行者が衝突して外側付近で接触した場合、障害を軽減することができる。また、歩行者が倒れた場合、歩行者が車輪に接触しづらくなることで、バンパーＳは、歩行者に対する安全性を向上させることができる。 Therefore, when a pedestrian collides near the outside of the vehicle in the vehicle width direction and contacts the pedestrian near the outside, the obstacle can be reduced. In addition, when a pedestrian falls down, the bumper S can improve the safety of the pedestrian by making it difficult for the pedestrian to contact the wheel.
