近年、安全性向上の観点から、車両の前端部のデザインのさらなる改善が図られており、衝突時等に潰れるよう調整された衝撃吸収部材を介してバンパビーム部材をサイドメンバ部材の先端部分に取り付けた車両の前端部構造が開発されている。
このような構造では、バンパビーム部材がラジエータコアサポート部材よりも大きく前方に突き出すこととなり、バンパビーム部材の高さ位置が歩行者の膝の高さ位置に略等しいため、バンパビーム部材が歩行者の膝に当たった場合、膝上部を支持する車体部材が無いため、歩行者の上体が膝の関節周りに大きく車両後方に倒れ込むおそれがあり、歩行者を十分に保護できず、好ましいことではない。 In recent years, from the viewpoint of improving safety, the design of the front end of the vehicle has been further improved, and the bumper beam member is attached to the front end portion of the side member member via an impact absorbing member adjusted so as to be crushed at the time of a collision. A vehicle front end structure has been developed.
In such a structure, the bumper beam member protrudes larger forward than the radiator core support member, and the height position of the bumper beam member is substantially equal to the height position of the pedestrian's knee. When hit, there is no vehicle body member that supports the upper part of the knee, so that the upper body of the pedestrian may fall largely around the knee joint and fall behind the vehicle, and the pedestrian cannot be sufficiently protected, which is not preferable.

本発明はこのような問題点を解決するためになされたもので、その目的とするところは、歩行者保護の向上を図ることの可能な車両の前端部構造を提供することにある。   The present invention has been made to solve such problems, and an object thereof is to provide a vehicle front end structure capable of improving pedestrian protection.

FIG. 1 is a perspective view of a front end structure of a vehicle according to the present invention.
As shown in the figure, the front end of the vehicle is roughly divided into a pair of left and right front side members 10 and 10, a radiator core support 20 joined to the upper end of the front side members 10 and 10, the front side member 10, The vehicle body is composed of a bumper beam 30 attached to the tip of 10 and a bumper force 40 according to the present invention.

なお、ここでは、車体部材であるフロントサイドメンバ１０、１０、ラジエータコアサポート２０、バンパビーム３０及び本発明に係るバンパリーンフォース４０についてのみ説明するが、車両の前端部には、図示しないものの、フロントサイドメンバ１０、１０の車両外側に位置してそれぞれフロントフェンダが配設され、ラジエータコアサポート２０及びバンパリーンフォース４０の上側に位置してフードが配設され、バンパビーム３０及びバンパリーンフォース４０を覆うようにして樹脂製のバンパフェイシアが設けられている。なお、ラジエータコアサポート２０は主として図示しないラジエータを支持するための部材である。   Here, only the front side members 10 and 10, the radiator core support 20, the bumper beam 30, and the bumper force 40 according to the present invention which are vehicle body members will be described. Front fenders are disposed on the outer sides of the side members 10 and 10, respectively, and hoods are disposed on the upper side of the radiator core support 20 and the bumper force 40 to cover the bumper beam 30 and the bumper force 40. In this way, a resin bumper fascia is provided. The radiator core support 20 is a member for mainly supporting a radiator (not shown).

詳しくは、フロントサイドメンバ１０、１０は、フロントサイドメンバ部材１２、１２の各先端にフランジ１４が形成されて構成され、ラジエータコアサポート２０は、アッパサポート部材２２と左右一対のサイドサポート部材２４、２４から構成されている。また、バンパビーム３０は、バンパビーム部材３２の車両前方が隙間を有してバンパコア３４で覆われるとともに、バンパビーム部材３２の左右両端部に、車両前方に突出し、潰れることで衝撃を吸収する左右一対のクラッシュ部材３６、３６が接合され、このクラッシュ部材３６、３６の各後端に上記フランジ１４に対応するフランジ３８がそれぞれ形成されて構成されている。   Specifically, the front side members 10 and 10 are configured by forming flanges 14 at the front ends of the front side member members 12 and 12, and the radiator core support 20 includes an upper support member 22 and a pair of left and right side support members 24 and 24. It is composed of The bumper beam 30 is covered with a bumper core 34 with a gap at the front side of the bumper beam member 32, and a pair of left and right crashes that protrudes to the front of the vehicle at both left and right ends of the bumper beam member 32 and absorbs shock by being crushed. Members 36 and 36 are joined, and flanges 38 corresponding to the flanges 14 are formed at the rear ends of the crash members 36 and 36, respectively.

そして、車両の前端部は、基本的に、フロントサイドメンバ部材１２、１２の先端部上面にサイドサポート部材２４、２４が接合され、フロントサイドメンバ部材１２、１２の各先端のフランジ１４がそれぞれクラッシュ部材３６、３６の各後端のフランジ３８と接合されて構成されている。
本発明に係るバンパリーンフォース４０は、左右一対のサイドブラケット４２、４２、一対の細長部材からなるステー４４、４４、バンパリーンフォース部材（補助部材）５０から構成されている。詳しくは、バンパリーンフォース４０は、バンパリーンフォース部材５０の両端がサイドサポート部材２４、２４から車両前方に延びるサイドブラケット４２、４２の先端部に接合されるとともに、バンパリーンフォース部材５０の中央部近傍とアッパサポート部材２２とを連結するように、一対のステー４４、４４の先端がバンパリーンフォース部材５０に接合され、後端がアッパサポート部材２２に接合されている。 The front end portion of the vehicle basically has side support members 24, 24 joined to the upper surfaces of the front end portions of the front side member members 12, 12, and the flanges 14 at the front ends of the front side member members 12, 12 are respectively crash members. 36 and 36 are joined to a flange 38 at each rear end.
The bumper force 40 according to the present invention includes a pair of left and right side brackets 42 and 42, stays 44 and 44 including a pair of elongated members, and a bumper force member (auxiliary member) 50. Specifically, the bumper force 40 has both ends of the bumper force member 50 joined to the front end portions of the side brackets 42 and 42 extending from the side support members 24 and 24 toward the front of the vehicle, and in the vicinity of the central portion of the bumper force member 50. The upper ends of the pair of stays 44 and 44 are joined to the bumper force member 50 and the rear ends are joined to the upper support member 22 so as to connect the upper support member 22 and the upper support member 22.

図３を参照すると、図１のＢ−Ｂ線に沿う断面図が示されているが、バンパリーンフォース部材５０は、断面がハット状をなし、平らな上面５２と車両前方に延びるフランジ５４を有している。
同図には、バンパフェイシア６０とフード７０とが合わせて示されているが、バンパリーンフォース４０はバンパフェイシア６０の上部を支持する機能を有し、バンパフェイシア６０の上部が上面５２に締結部材によって固定されている。これより、バンパフェイシア６０は、上部がバンパリーンフォース４０に固定され、下部が例えばバンパビーム３０のバンパコア３４の下面に締結部材によって固定されるようにして車両の前端部に設けられている。 Referring to FIG. 3, a sectional view taken along line BB in FIG. 1 is shown. The bumper force member 50 has a hat-like cross section, and has a flat upper surface 52 and a flange 54 extending forward of the vehicle. Have.
In the drawing, the bumper fascia 60 and the hood 70 are shown together, but the bumper force 40 has a function of supporting the upper part of the bumper fascia 60, and the upper part of the bumper fascia 60 is a fastening member on the upper surface 52. It is fixed by. Accordingly, the bumper fascia 60 is provided at the front end portion of the vehicle such that the upper portion is fixed to the bumper force 40 and the lower portion is fixed to the lower surface of the bumper core 34 of the bumper beam 30 with a fastening member, for example.

そして、バンパリーンフォース４０は、車両の前端部が歩行者と接触した場合に、歩行者を保護する機能をも有している。即ち、バンパビーム３０の高さ位置が歩行者の膝の高さ位置に略等しいため、バンパビーム３０が歩行者の膝に当たった場合、歩行者の上体が膝の関節周りに大きく車両後方に倒れ込むおそれがあるのであるが、バンパリーンフォース４０のバンパリーンフォース部材５０が、歩行者の脚上部を支え、かかる歩行者の上体の車両後方への倒れ込みを防止する機能を有している。   The bumper force 40 also has a function of protecting the pedestrian when the front end of the vehicle comes into contact with the pedestrian. In other words, since the height position of the bumper beam 30 is substantially equal to the height position of the pedestrian's knee, when the bumper beam 30 hits the pedestrian's knee, the upper body of the pedestrian falls largely around the knee joint and falls backward in the vehicle. There is a possibility that the bumper force member 50 of the bumper force 40 has a function of supporting the upper leg portion of the pedestrian and preventing the upper body of the pedestrian from falling backward in the vehicle.

図４を参照すると、図３に加え、歩行者の脚部１００が車両の前端部に接触した場合の歩行者の脚部１００の挙動が示されているが、同図に示すように、歩行者の脚部１００は、略同時に膝１０２がバンパビーム３０の位置でバンパフェイシア６０と接触するとともに、脚上部１０４がバンパリーンフォース部材５０の位置でバンパフェイシア６０と接触する（二点鎖線）。   Referring to FIG. 4, in addition to FIG. 3, the behavior of the pedestrian's leg 100 when the pedestrian's leg 100 contacts the front end of the vehicle is shown. As shown in FIG. The leg portion 100 of the person is in contact with the bumper fascia 60 at the position of the bumper beam 30 and the upper leg portion 104 is in contact with the bumper facia 60 at the position of the bumper force member 50 (two-dot chain line).

そして、車両が前方に走行している場合、歩行者の脚部１００がバンパフェイシア６０に接触した後、脚上部１０４はバンパリーンフォース部材５０と当接することになる（実線）。
このように脚上部１０４がバンパリーンフォース部材５０と当接すると、歩行者の上体は膝１０２の関節周りに車両後方に倒れ込むことが殆ど無くなり、車両の前端部が歩行者と接触した場合であっても、歩行者が受ける被害を最小限に留めることができ、歩行者保護の向上を図ることができる。 When the vehicle is traveling forward, the leg upper part 104 comes into contact with the bumper force member 50 after the leg part 100 of the pedestrian contacts the bumper fascia 60 (solid line).
When the upper leg 104 is in contact with the bumper force member 50 in this manner, the upper body of the pedestrian hardly falls back around the joint of the knee 102 and the front end of the vehicle comes into contact with the pedestrian. Even if it exists, the damage which a pedestrian receives can be suppressed to the minimum, and the improvement of pedestrian protection can be aimed at.

特に、バンパリーンフォース部材５０は、ハット状の断面を有していることからある程度の剛性が確保されているが、下面が開放されているので、歩行者と接触した場合に変形して衝撃力を吸収可能である。また、一対のステー４４、４４は細長部材からなるので、ステー４４、４４が座屈することによっても衝撃力を吸収可能であり、歩行者の受ける衝撃を良好に緩和することができる。   In particular, the bumper force member 50 has a hat-shaped cross section, so that a certain degree of rigidity is ensured. However, since the lower surface is opened, the bumper force member 50 is deformed when it comes into contact with a pedestrian and has an impact force. Can be absorbed. Further, since the pair of stays 44 and 44 are formed of an elongated member, the impact force can be absorbed even when the stays 44 and 44 are buckled, and the impact received by the pedestrian can be mitigated well.

さらに、本実施形態では、バンパリーンフォース部材５０は車両前方に延びるフランジ５４を有していることから、フランジ５４が歩行者と接触した場合に変形することによっても衝撃力を吸収可能であり、歩行者の受ける衝撃をさらに緩和することができる。
この場合において、フランジ５４の長さを適宜設定することにより、歩行者の膝１０２の曲げ角度を規制することが可能である。 Further, in the present embodiment, the bumper force member 50 has a flange 54 extending forward of the vehicle, and therefore, the impact force can be absorbed by deformation when the flange 54 comes into contact with a pedestrian. The impact received by pedestrians can be further reduced.
In this case, it is possible to regulate the bending angle of the pedestrian's knee 102 by appropriately setting the length of the flange 54.

また、図５を参照すると、本発明に係る車両の前端部構造の変形例が図３と同様に示されており、同図に示すように、バンパリーンフォース部材５０に代えて、フランジ５４’に当該フランジ５４’に沿って延びるビード５６を形成したバンパリーンフォース部材５０’を採用するようにしてもよい。
このようにフランジ５４’にビード５６が形成されていると、フランジ５４’が歩行者と接触した場合において容易に変形して衝撃力を吸収可能であり、歩行者の受ける衝撃をより一層緩和することができる。これにより、さらなる歩行者保護の向上を図ることができる。 Referring to FIG. 5, a modified example of the vehicle front end structure according to the present invention is shown in the same manner as FIG. 3. As shown in FIG. 5, a flange 54 ′ is used instead of the bumper force member 50. Alternatively, a bumper force member 50 ′ having a bead 56 extending along the flange 54 ′ may be employed.
When the bead 56 is formed on the flange 54 ′ as described above, when the flange 54 ′ comes into contact with the pedestrian, the bead 56 can be easily deformed to absorb the impact force and further reduce the impact received by the pedestrian. be able to. Thereby, the improvement of further pedestrian protection can be aimed at.
