Description

本発明は、車体前部構造に関する。   The present invention relates to a vehicle body front structure.

下記特許文献１に記載された車体前部構造では、サイドメンバの車両前側部分を構成するサイドメンバ前方領域が車両前側へ向かうに従い車両幅方向外側へ屈曲されている。また、サイドメンバ前方領域の連設基部からサブサイドメンバが車両前側へ延びており、サブサイドメンバはサイドメンバに結合されている。さらに、サブサイドメンバには、２箇所のノッチが形成されている。これにより、サイドメンバの車両前方部分が、車両前側へ開放された二股状に形成されて、バンパーレインフォースと結合されている。   In the vehicle body front part structure described in Patent Document 1 below, a side member front region constituting a vehicle front side portion of the side member is bent outward in the vehicle width direction toward the vehicle front side. Moreover, the sub side member is extended from the continuous base part of the side member front area | region to the vehicle front side, and the sub side member is couple | bonded with the side member. Furthermore, two notches are formed in the sub-side member. Thereby, the vehicle front portion of the side member is formed in a bifurcated shape opened to the vehicle front side, and is coupled to the bumper reinforcement.

そして、車両が相手車両等の衝突体とサイドメンバよりも車両幅方向外側で前面衝突（所謂微小ラップ衝突）する際には、サイドメンバ前方領域が圧縮変形すると共に、サブサイドメンバがノッチ部分を起点に折れ曲がる。これにより、車両後側への衝突荷重が車両幅方向内側への横力として変換される。   When the vehicle has a frontal collision (so-called minute lap collision) on the outer side in the vehicle width direction with respect to the collision body such as the opponent vehicle and the side member, the front region of the side member is compressed and deformed, and the sub-side member has a notch portion. Bend at the starting point. Thereby, the collision load to the vehicle rear side is converted as a lateral force inward in the vehicle width direction.

しかしながら、上記の車体前部構造では、サイドメンバ前方領域の耐圧縮変形荷重が低いと、微小ラップ衝突時にサイドメンバ前方領域におけるサイドメンバへの荷重伝達効率が低下する。また、前面衝突時にもサイドメンバ前方領域に圧縮方向への荷重が作用するため、サイドメンバ前方領域の耐圧縮変形荷重が高いと、前面衝突時にサイドメンバ前方領域の圧縮変形（塑性変形）が確保されず、衝突荷重の吸収が不十分になる可能性がある。   However, in the vehicle body front structure described above, if the compressive deformation load in the front region of the side member is low, the load transmission efficiency to the side member in the front region of the side member is reduced at the time of a minute lap collision. Also, since a load in the compression direction acts on the front region of the side member even during a frontal collision, a high compressive deformation load in the front region of the side member ensures a compressive deformation (plastic deformation) in the front region of the side member during a frontal collision. The impact load may be insufficiently absorbed.

本発明は、上記事実を考慮し、前面衝突時における衝撃吸収性を確保しつつ微小ラップ衝突時に衝突荷重をフロントサイドメンバへ効率よく伝達できる車体前部構造を提供することを目的とする。   In consideration of the above facts, an object of the present invention is to provide a vehicle body front structure capable of efficiently transmitting a collision load to a front side member at the time of a minute lap collision while ensuring shock absorption at the time of a frontal collision.

請求項１に記載の車体前部構造は、車両前部の車両幅方向両側部に設けられ、車両前後方向に延びる一対のフロントサイドメンバと、前記フロントサイドメンバよりも車両前側に設けられ、車両の意匠を形成するフロントバンパカバーと、前記フロントサイドメンバよりも車両幅方向外側に設けられた前輪と、前記フロントバンパカバーと、の間に設けられ、車両上下方向を幅方向にした帯状に形成されると共に、車両幅方向内側の一端部が前記フロントサイドメンバに直接的又は間接的に結合され、前記一端部から前記前輪の車両前側へ延びて、他端部が車両用構成部材に結合された帯状部材と、を備えている。   The vehicle body front portion structure according to claim 1 is provided on both sides of the vehicle front portion in the vehicle width direction, and is provided on the vehicle front side with respect to the pair of front side members extending in the vehicle front-rear direction and the front side members. The front bumper cover that forms the design of the vehicle, the front wheel provided on the outer side in the vehicle width direction from the front side member, and the front bumper cover are formed in a belt shape in the width direction in the vehicle vertical direction. In addition, one end portion in the vehicle width direction is directly or indirectly coupled to the front side member, extends from the one end portion to the vehicle front side of the front wheel, and the other end portion is coupled to the vehicle component. And a belt-shaped member.

請求項１に記載の車体前部構造では、車両前後方向に延びる一対のフロントサイドメンバが、車両前部の車両幅方向両側部に設けられている。また、フロントサイドメンバよりも車両前側にはフロントバンパカバーが設けられており、フロントバンパカバーは、車両の意匠を形成している。さらに、フロントサイドメンバの車両幅方向外側には前輪が設けられている。   In the vehicle body front portion structure according to the first aspect, the pair of front side members extending in the vehicle front-rear direction are provided on both sides of the vehicle front portion in the vehicle width direction. Further, a front bumper cover is provided on the front side of the vehicle with respect to the front side member, and the front bumper cover forms a design of the vehicle. Further, a front wheel is provided on the outer side of the front side member in the vehicle width direction.

ここで、前輪とフロントバンパカバーとの間には帯状部材が設けられており、帯状部材は、車両上下方向を幅方向にして配置されている。また、帯状部材における車両幅方向内側の一端部がフロントサイドメンバに直接的又は間接的に結合されており、帯状部材は、一端部から前輪の車両前側へ延びている。そして、帯状部材の他端部が車両用構成部材に結合されている。   Here, a belt-like member is provided between the front wheel and the front bumper cover, and the belt-like member is arranged with the vehicle vertical direction as the width direction. Further, one end of the belt-like member on the inner side in the vehicle width direction is directly or indirectly coupled to the front side member, and the belt-like member extends from the one end to the front side of the front wheel. And the other end part of a strip | belt-shaped member is couple | bonded with the structural member for vehicles.

このため、車両が微小ラップ衝突すると、フロントバンパカバーに衝突した衝突体が帯状部材側（車両後側）へ移動する。その後、帯状部材が衝突体と前輪の前端部との間に挟み込まれて、この状態で帯状部材が衝突体及び前輪と共に車両後側へ移動しようとする。このため、帯状部材の一端部が前輪の前端部よりも車両前側に配置されることで（前輪が車両後側へ移動されて当該一端部が前輪の前端部よりも車両前側に配置された場合も含む）、引張荷重（張力）が帯状部材に作用する。これにより、衝突荷重が帯状部材を介してフロントサイドメンバへ伝達される。   For this reason, when the vehicle collides with a minute lap, the collision body that has collided with the front bumper cover moves to the belt-like member side (vehicle rear side). Thereafter, the belt-like member is sandwiched between the collision body and the front end portion of the front wheel, and in this state, the belt-like member tends to move to the vehicle rear side together with the collision body and the front wheel. For this reason, one end of the belt-shaped member is arranged on the front side of the vehicle from the front end of the front wheel (when the front wheel is moved to the rear side of the vehicle and the one end is arranged on the front side of the vehicle from the front end of the front wheel. And a tensile load (tension) acts on the belt-shaped member. Thereby, the collision load is transmitted to the front side member via the belt-like member.

さらに、上述のように引張荷重が帯状部材に作用するため、帯状部材の引張強度を有効に活用して、衝突荷重をフロントサイドメンバへ伝達できる。したがって、帯状部材によって衝突荷重をフロントサイドメンバへ効率よく伝達できる。   Furthermore, since the tensile load acts on the belt-like member as described above, the collision load can be transmitted to the front side member by effectively utilizing the tensile strength of the belt-like member. Therefore, the collision load can be efficiently transmitted to the front side member by the belt-like member.

一方、車両が前面衝突すると、フロントサイドメンバに車両後方側への衝突荷重が伝達される。このため、前面衝突時における衝突荷重をフロントサイドメンバによって吸収できる。   On the other hand, when the vehicle collides front, a collision load toward the vehicle rear side is transmitted to the front side member. For this reason, the collision load at the time of frontal collision can be absorbed by the front side member.

請求項２に記載の車体前部構造では、帯状部材の一端部が前輪よりも車両前側に配置されているため、車両の微小ラップ衝突時に衝突体と前輪との間に帯状部材が挟み込まれた際に、引張荷重が帯状部材に早期に発生する。これにより、衝突荷重をフロントサイドメンバへ早期に伝達できる。   In the vehicle body front part structure according to claim 2, since the one end portion of the belt-like member is disposed on the vehicle front side with respect to the front wheel, the belt-like member is sandwiched between the collision body and the front wheel at the time of a minute lap collision of the vehicle. In this case, a tensile load is generated early on the belt-shaped member. Thereby, the collision load can be transmitted to the front side member at an early stage.

請求項３に記載の車体前部構造は、請求項２に記載の車体前部構造において、前記帯状部材の一端部は前記フロントサイドメンバに結合されると共に、前記帯状部材は、前記一端部から車両後側へ延びる延出部と、前記延出部の後端部から車両幅方向外側へ延びて前記延出部と前記他端部とを連結する連結部と、を含んで構成されている。   The vehicle body front structure according to claim 3 is the vehicle body front structure according to claim 2, wherein one end portion of the belt-shaped member is coupled to the front side member, and the belt-shaped member is connected to the one end portion.

延出部３８は、平面視で、一端部３２から車両幅方向外側へ向かうに従い車両後側へ延びている。また、連結部４０は、前輪２０の車両前側に配置されて、延出部３８の後端部から車両幅方向外側へ延びており、連結部４０の車両幅方向外側端部が他端部３４の後端部と一体に接続されている。   The extension portion 38 extends toward the vehicle rear side from the one end portion 32 toward the outside in the vehicle width direction in plan view. The connecting portion 40 is disposed on the vehicle front side of the front wheel 20 and extends outward from the rear end portion of the extending portion 38 in the vehicle width direction. The vehicle width direction outer end portion of the connecting portion 40 is the other end portion 34. Is connected to the rear end of the unit.

次に、車両１０が微小ラップ衝突する場合と車両１０が前面衝突する場合とを説明しつつ、第１の実施の形態の作用及び効果について説明する。   Next, the operation and effect of the first embodiment will be described while explaining the case where the vehicle 10 collides with a minute lap and the case where the vehicle 10 collides with the front.

図２（Ａ）に示されるように、車体前部構造Ｓ１が適用された車両１０が衝突体Ｄと微小ラップ衝突すると、衝突体Ｄが、フロントバンパカバー１８の車両幅方向外側部分に衝突すると共に、車両後方側へ移動する。そして、フロントバンパカバー１８の車両幅方向外側部分が衝突体Ｄに沿うように変形すると共に、フロントバンパカバー１８の車両幅方向外側端部が車両幅方向外側へ変位する。これにより、フロントバンパカバー１８と帯状部材３０の他端部３４との結合が解除されて、帯状部材３０の他端部３４が車両幅方向外側へ変位する。   As shown in FIG. 2A, when the vehicle 10 to which the vehicle body front structure S <b> 1 is applied collides with the collision body D, the collision body D collides with the outer portion of the front bumper cover 18 in the vehicle width direction. At the same time, it moves to the vehicle rear side. And while the vehicle width direction outer side part of the front bumper cover 18 deform | transforms along the collision body D, the vehicle width direction outer side edge part of the front bumper cover 18 displaces to a vehicle width direction outer side. Thereby, the coupling | bonding of the front bumper cover 18 and the other end part 34 of the strip | belt-shaped member 30 is cancelled | released, and the other end part 34 of the strip | belt-shaped member 30 is displaced to the vehicle width direction outer side.

この状態で衝突体Ｄが車両後方側へさらに移動すると、フロントバンパカバー１８及びフェンダライナ２４を介して帯状部材３０が衝突体Ｄと前輪２０の前端部との間に挟み込まれる（図２（Ｂ）参照）。この時、衝突体Ｄ及び前輪２０によって挟み込まれた帯状部材３０の部位よりも帯状部材３０の一端部３２が車両前側に配置されており、衝突体Ｄは車両後方側へさらに移動しようとしているため、引張荷重（張力）が帯状部材３０に作用する。これにより、衝突荷重が帯状部材３０を介してサイドメンバ１２へ伝達される。   When the collision body D further moves to the vehicle rear side in this state, the belt-like member 30 is sandwiched between the collision body D and the front end portion of the front wheel 20 via the front bumper cover 18 and the fender liner 24 (FIG. 2B )reference). At this time, one end portion 32 of the belt-like member 30 is disposed on the vehicle front side rather than the portion of the belt-like member 30 sandwiched between the collision body D and the front wheel 20, and the collision body D is about to move further to the vehicle rear side. A tensile load (tension) acts on the belt-shaped member 30. Thereby, the collision load is transmitted to the side member 12 through the belt-shaped member 30.

さらに、上述したように、帯状部材３０に引張荷重が作用するため、帯状部材３０の引張強度を有効に活用して衝突荷重をサイドメンバ１２に伝達できる。したがって、帯状部材３０によって衝突荷重をサイドメンバ１２へ効率よく伝達できる。   Furthermore, as described above, since the tensile load acts on the band-shaped member 30, the collision load can be transmitted to the side member 12 by effectively utilizing the tensile strength of the band-shaped member 30. Therefore, the collision load can be efficiently transmitted to the side member 12 by the belt-shaped member 30.

一方、車両１０が前面衝突すると、車両後方側への衝突荷重がバンパＲ／Ｆ１６及びクラッシュボックス１４を介して、サイドメンバ１２に伝達される。そして、この衝突荷重がクラッシュボックス１４の耐圧縮変形荷重を上回ると、クラッシュボックス１４が車両前後方向に圧縮変形する。これにより、前面衝突時における衝突荷重を吸収できる。   On the other hand, when the vehicle 10 collides frontward, a collision load on the vehicle rear side is transmitted to the side member 12 via the bumper R / F 16 and the crash box 14. When the collision load exceeds the compression deformation load of the crash box 14, the crash box 14 is compressed and deformed in the vehicle front-rear direction. Thereby, the collision load at the time of frontal collision can be absorbed.

また、帯状部材３０の一端部３２が、前輪２０よりも車両前側に配置されてサイドメンバ１２と結合されている。これにより、微小ラップ衝突時に衝突体Ｄと前輪２０との間に帯状部材３０が挟み込まれた際に引張荷重が帯状部材３０に早期に発生するため、衝突荷重をサイドメンバ１２へ早期に伝達できる。   Further, one end portion 32 of the belt-shaped member 30 is disposed on the vehicle front side with respect to the front wheel 20 and is coupled to the side member 12. Thereby, when the belt-like member 30 is sandwiched between the collision body D and the front wheel 20 at the time of the minute lap collision, the tensile load is generated in the belt-like member 30 early, so that the collision load can be transmitted to the side member 12 early. .

さらに、帯状部材３０の延出部３８が、一端部３２から車両幅方向外側へ向かうに従い車両後側へ延びており、連結部４０が延出部３８の後端部から車両幅方向外側へ延びている。これにより、仮に、帯状部材３０において延出部３８が省略された場合（連結部４０によって一端部３２と他端部３４とを連結すると共に、一端部３２とサイドメンバ１２との結合部分を車両後側へ移動する場合）に比べて、帯状部材３０の長手方向の長さを長くできる。したがって、微小ラップ衝突時に帯状部材３０に作用する引張荷重に対する帯状部材３０の許容応力を高く設定できる。   Further, the extending portion 38 of the belt-like member 30 extends toward the vehicle rear side from the one end portion 32 toward the vehicle width direction outer side, and the connecting portion 40 extends from the rear end portion of the extending portion 38 to the vehicle width direction outer side. ing. Thereby, if the extension part 38 is omitted in the belt-shaped member 30 (the connecting part 40 connects the one end part 32 and the other end part 34 and the connecting part between the one end part 32 and the side member 12 is connected to the vehicle. The length in the longitudinal direction of the belt-like member 30 can be increased compared to the case of moving to the rear side. Therefore, the allowable stress of the belt-shaped member 30 with respect to the tensile load acting on the belt-shaped member 30 at the time of a minute lap collision can be set high.

また、前輪２０とフロントバンパカバー１８との間に帯状部材３０が設けられているため、微小ラップ衝突時に前輪２０やアーム２２が車両１０から脱落することを抑制でき、前輪２０がロッカの車両幅方向内側へ入り込むことを抑制できる。すなわち、仮に帯状部材３０を省略した車両が微小ラップ衝突して衝突体Ｄが前輪２０に当たると、前輪２０を支持するアーム２２が前輪２０の車両幅方向内側に配置されているため、前輪２０の前端部に車両幅方向外側へのモーメントが作用する。その結果、前輪２０やアーム２２が車両１０から車両幅方向外側へ脱落する可能性がある。また、この際には、前輪２０の前端部が車両幅方向外側へ回転するため、前輪２０の後端部が車両幅方向内側へ回転されて、前輪２０がロッカの車両幅方向内側へ入り込み易くなる。   Further, since the belt-like member 30 is provided between the front wheel 20 and the front bumper cover 18, it is possible to suppress the front wheel 20 and the arm 22 from falling off the vehicle 10 at the time of a minute lap collision, and the front wheel 20 is a vehicle width of the rocker. It is possible to suppress entry into the inside of the direction. That is, if a vehicle with the belt-like member 30 omitted is subjected to a minute lap collision and the colliding body D hits the front wheel 20, the arm 22 that supports the front wheel 20 is disposed on the inner side in the vehicle width direction of the front wheel 20. A moment to the outside in the vehicle width direction acts on the front end portion. As a result, the front wheel 20 and the arm 22 may fall off from the vehicle 10 in the vehicle width direction. Further, at this time, since the front end portion of the front wheel 20 rotates outward in the vehicle width direction, the rear end portion of the front wheel 20 is rotated inward in the vehicle width direction, and the front wheel 20 easily enters the inside of the rocker in the vehicle width direction. Become.

一方、第１の実施の形態では、上述したように、車両１０が微小ラップ衝突して帯状部材３０が前輪２０と衝突体Ｄとによって挟み込まれた際に、帯状部材３０に引張荷重が作用する。このため、帯状部材３０と前輪２０（フェンダライナ２４）との間の摩擦力によって、前輪２０の前端部に車両幅方向内側へのモーメントが作用する。これにより、前輪２０の前端部に車両幅方向外側へのモーメントが作用することが抑制されて、微小ラップ衝突時に前輪２０やアーム２２が車両１０から脱落することを抑制できる。また、前輪２０の前端部に車両幅方向内側へのモーメントが作用することで、前輪２０の後端部が車両幅方向外側へ回転されるため、前輪２０がロッカの車両幅方向内側へ入り込むことを抑制できる。   On the other hand, in the first embodiment, as described above, a tensile load is applied to the band-shaped member 30 when the vehicle 10 collides with a minute lap and the band-shaped member 30 is sandwiched between the front wheel 20 and the collision body D. . For this reason, a moment inward in the vehicle width direction acts on the front end portion of the front wheel 20 by the frictional force between the belt-like member 30 and the front wheel 20 (fender liner 24). Thereby, it is suppressed that the moment to the vehicle width direction outer side acts on the front-end part of the front wheel 20, and it can suppress that the front wheel 20 and the arm 22 drop from the vehicle 10 at the time of a micro lap collision. Further, the moment toward the vehicle width direction inner side acts on the front end portion of the front wheel 20, so that the rear end portion of the front wheel 20 is rotated outward in the vehicle width direction, so that the front wheel 20 enters the rocker inward in the vehicle width direction. Can be suppressed.

なお、第１の実施の形態では、帯状部材３０の一端部３２が、前輪２０の車両前側に配置されてサイドメンバ１２と結合されている。これに替えて、帯状部材３０の一端部３２の位置を前輪２０の前端部よりも車両後側に設定してもよい。すなわち、この場合でも、微小ラップ衝突時に前輪２０が車両後側へ移動されて一端部３２が前輪２０の前端部よりも車両前側に配置されることで、帯状部材３０に引張荷重を作用させることができる。これにより、例えば、前輪２０の前端部よりも車両後側に一端部３２を配置すると共に、一端部３２と前輪２０の前端部との車両前後方向の距離を、前輪２０とロッカとの車両前後方向の距離より短く設定した場合には、前輪２０がロッカに当たる前に帯状部材３０に引張荷重を作用させることができる。   In the first embodiment, one end portion 32 of the belt-like member 30 is disposed on the vehicle front side of the front wheel 20 and coupled to the side member 12. Instead of this, the position of the one end portion 32 of the belt-shaped member 30 may be set on the vehicle rear side with respect to the front end portion of the front wheel 20. That is, even in this case, the front wheel 20 is moved to the rear side of the vehicle at the time of the minute lap collision, and the one end portion 32 is arranged on the front side of the vehicle with respect to the front end portion of the front wheel 20, so Can do. Thereby, for example, the one end portion 32 is disposed on the vehicle rear side with respect to the front end portion of the front wheel 20, and the distance in the vehicle front-rear direction between the one end portion 32 and the front end portion of the front wheel 20 is set to the vehicle front-rear direction between the front wheel 20 and the rocker. When the distance is set shorter than the distance in the direction, a tensile load can be applied to the belt-shaped member 30 before the front wheel 20 hits the rocker.

また、第１の実施の形態では、帯状部材３０は延出部３８を有している。これに代えて、帯状部材３０において、延出部３８を省略してもよい。すなわち、連結部４０によって一端部３２と他端部３４とを連結すると共に、一端部３２とサイドメンバ１２との結合部分を車両後側へ移動してもよい。   Further, in the first embodiment, the belt-shaped member 30 has an extending portion 38. Instead of this, the extension 38 may be omitted from the belt-shaped member 30. That is, the one end portion 32 and the other end portion 34 may be connected by the connecting portion 40, and the connecting portion between the one end portion 32 and the side member 12 may be moved to the vehicle rear side.

さらに、第１の実施の形態では、帯状部材３０の延出部３８が、一端部３２から車両幅方向外側へ向かうに従い車両後側へ延びている。これに代えて、延出部３８を一端部３２から車両後側へ延ばしてサイドメンバ１２に沿うよう配置すると共に、延出部３８の後端部をクリップ等でサイドメンバ１２に結合してもよい。   Furthermore, in the first embodiment, the extending portion 38 of the belt-shaped member 30 extends toward the vehicle rear side from the one end portion 32 toward the outside in the vehicle width direction. Instead of this, the extending portion 38 extends from the one end portion 32 toward the rear side of the vehicle and is arranged along the side member 12, and the rear end portion of the extending portion 38 is coupled to the side member 12 with a clip or the like. Good.

（第２の実施の形態） (Second Embodiment)

第２の実施の形態に係る車体前部構造Ｓ２が適用された車両１００では、第１の実施の形態の車両１０と比べて、帯状部材３０の形状及び配置位置が相違すると共に、荷重伝達部材１０２が新たに追加されている。以下、図３を用いて第２の実施の形態における帯状部材３０及び荷重伝達部材１０２について説明する。   In the vehicle 100 to which the vehicle body front structure S2 according to the second embodiment is applied, the shape and arrangement position of the belt-shaped member 30 are different from those of the vehicle 10 according to the first embodiment, and the load transmission member. 102 is newly added. Hereinafter, the belt-like member 30 and the load transmitting member 102 in the second embodiment will be described with reference to FIG.

図３には、車体前部構造Ｓ２が適用された車両１００が模式的な平面図にて示されている。この図に示されるように、帯状部材３０は、平面視で車両幅方向内側へ開放された略Ｖ字形状に形成されている。そして、帯状部材３０の一端部３２は、バンパＲ／Ｆ１６における車両幅方向外側端部の前面に結合されている。これにより、帯状部材３０の一端部３２が、バンパＲ／Ｆ１６及びクラッシュボックス１４を介してサイドメンバ１２に結合されている。また、帯状部材３０の延出部３８は、一端部３２からフロントバンパカバー１８に沿うように車両幅方向外側へ向かうに従い車両後側へ曲線状に延びている。さらに、帯状部材３０の連結部４０は、延出部３８の後端部から車両幅方向内側へ延びると共に、前輪２０及びフェンダライナ２４のアーチ部２６よりも車両前側に配置されている。そして、帯状部材３０の他端部３４が、アーチ部２６に結合されている。これにより、フェンダライナ２４が本発明の車両用構成部材に対応している。   FIG. 3 is a schematic plan view showing the vehicle 100 to which the vehicle body front structure S2 is applied. As shown in this figure, the belt-like member 30 is formed in a substantially V-shape that is opened inward in the vehicle width direction in plan view. And the one end part 32 of the strip | belt-shaped member 30 is couple | bonded with the front surface of the vehicle width direction outer side edge part in bumper R / F16. Thereby, the one end portion 32 of the belt-shaped member 30 is coupled to the side member 12 via the bumper R / F 16 and the crash box 14. Further, the extending portion 38 of the belt-shaped member 30 extends in a curved shape from the one end portion 32 toward the vehicle rear side along the front side in the vehicle width direction along the front bumper cover 18. Further, the connecting portion 40 of the belt-like member 30 extends inward in the vehicle width direction from the rear end portion of the extending portion 38, and is disposed on the vehicle front side with respect to the front wheel 20 and the arch portion 26 of the fender liner 24. The other end portion 34 of the belt-shaped member 30 is coupled to the arch portion 26. Thus, the fender liner 24 corresponds to the vehicle component of the present invention.

荷重伝達部材１０２は、平面視で略台形のブロック状に形成されて、前輪２０の車両前側でかつ延出部３８の車両幅方向内側に配置されている。なお、荷重伝達部材１０２が取付けられる部材は任意に設定することができる。   The load transmission member 102 is formed in a substantially trapezoidal block shape in plan view, and is disposed on the vehicle front side of the front wheel 20 and on the vehicle width direction inner side of the extending portion 38. The member to which the load transmission member 102 is attached can be set arbitrarily.

そして、図４に示されるように、車両１００が微小ラップ衝突すると、衝突体Ｄが、フロントバンパカバー１８の車両幅方向外側部分に衝突すると共に、車両後方側へ移動する。この際には、フロントバンパカバー１８の車両幅方向外側部分及び帯状部材３０は衝突体Ｄに沿うように変形すると共に、帯状部材３０の他端部３４が車両幅方向外側へ変位する。これにより、フェンダライナ２４と帯状部材３０の他端部３４との結合が解除される。   As shown in FIG. 4, when the vehicle 100 collides with a minute lap, the collision body D collides with the outer portion of the front bumper cover 18 in the vehicle width direction and moves to the vehicle rear side. At this time, the outer portion of the front bumper cover 18 in the vehicle width direction and the belt-like member 30 are deformed along the collision body D, and the other end 34 of the belt-like member 30 is displaced outward in the vehicle width direction. Thereby, the coupling | bonding of the fender liner 24 and the other end part 34 of the strip | belt-shaped member 30 is cancelled | released.

この状態で衝突体Ｄが車両後方側へさらに移動すると、帯状部材３０が荷重伝達部材１０２に接触し、荷重伝達部材１０２が帯状部材３０と共に車両後方側へ移動する。そして、衝突体Ｄが車両後方側へさらに移動すると、フロントバンパカバー１８、荷重伝達部材１０２、及びフェンダライナ２４を介して帯状部材３０が衝突体Ｄと前輪２０とによって挟み込まれる。この時、衝突体Ｄ及び前輪２０に挟み込まれた帯状部材３０の部位よりも帯状部材３０の一端部３２が車両前側に配置されており、衝突体Ｄは車両後方側へさらに移動しようとしているため、帯状部材３０に引張荷重が作用する。これにより、衝突荷重が帯状部材３０を介してサイドメンバ１２へ伝達される。以上により、第２の実施の形態においても、第１の実施の形態と同様の作用及び効果を奏する。   When the collision body D further moves to the vehicle rear side in this state, the belt-shaped member 30 comes into contact with the load transmission member 102, and the load transmission member 102 moves to the vehicle rear side together with the belt-shaped member 30. When the collision body D further moves to the vehicle rear side, the belt-shaped member 30 is sandwiched between the collision body D and the front wheel 20 via the front bumper cover 18, the load transmission member 102, and the fender liner 24. At this time, one end portion 32 of the belt-like member 30 is arranged on the vehicle front side rather than the part of the belt-like member 30 sandwiched between the collision body D and the front wheel 20, and the collision body D is going to move further to the vehicle rear side. A tensile load acts on the band-shaped member 30. Thereby, the collision load is transmitted to the side member 12 through the belt-shaped member 30. As described above, also in the second embodiment, the same operations and effects as in the first embodiment can be obtained.

また、第２の実施の形態では、帯状部材３０の延出部３８が、一端部３２からフロントバンパカバー１８に沿うように車両後側へ向かうに従い車両幅方向外側へ傾斜して配置されており、連結部４０が延出部３８の後端部から車両幅方向内側へ延びて、他端部３４と延出部３８とが連結されている。これにより、第２の実施の形態の帯状部材３０についても、帯状部材３０の長手方向の長さを長く設定できる。したがって、車両１００が衝突体Ｄと微小ラップ衝突する際に、帯状部材３０に作用する引張荷重に対する帯状部材の許容応力を高く設定できる。   Further, in the second embodiment, the extending portion 38 of the belt-like member 30 is disposed to be inclined outward in the vehicle width direction from the one end portion 32 along the front bumper cover 18 toward the vehicle rear side. The connecting portion 40 extends inward in the vehicle width direction from the rear end portion of the extending portion 38, and the other end portion 34 and the extending portion 38 are connected. Thereby, also about the strip | belt-shaped member 30 of 2nd Embodiment, the length of the longitudinal direction of the strip | belt-shaped member 30 can be set long. Therefore, when the vehicle 100 collides with the collision body D with a minute lap, the allowable stress of the strip member with respect to the tensile load acting on the strip member 30 can be set high.

さらに、第２の実施の形態では、帯状部材３０の一端部３２がバンパＲ／Ｆ１６に結合されている。これにより、微小ラップ衝突時に帯状部材３０に作用する引張荷重がバンパＲ／Ｆ１６を介して一対のサイドメンバ１２に伝達されるため、微小ラップ衝突時の衝突荷重を一対のサイドメンバ１２に効率よく分散させることができる。   Furthermore, in the second embodiment, one end 32 of the belt-like member 30 is coupled to the bumper R / F 16. As a result, the tensile load acting on the belt-like member 30 at the time of the minute lap collision is transmitted to the pair of side members 12 via the bumper R / F 16, so the collision load at the time of the minute lap collision is efficiently applied to the pair of side members 12. Can be dispersed.

また、第２の実施の形態では、荷重伝達部材１０２が前輪２０の車両前側に配置されている。このため、荷重伝達部材１０２によって帯状部材３０を衝突体Ｄと前輪２０との間に早期に挟み込ませることができる。これにより、引張荷重が帯状部材３０に早期に発生して、衝突荷重をサイドメンバ１２に早期に伝達できる。   Further, in the second embodiment, the load transmission member 102 is disposed on the front side of the front wheel 20 in the vehicle. For this reason, the belt-like member 30 can be sandwiched between the collision body D and the front wheel 20 at an early stage by the load transmission member 102. As a result, a tensile load is generated in the belt-shaped member 30 at an early stage, and the collision load can be transmitted to the side member 12 at an early stage.

なお、第２の実施の形態では、荷重伝達部材１０２が連結部４０の車両前側に配置されているが、荷重伝達部材１０２を省略してもよい。   In the second embodiment, the load transmission member 102 is disposed on the vehicle front side of the connecting portion 40, but the load transmission member 102 may be omitted.

また、第１の実施の形態及び第２の実施の形態では、帯状部材３０がアラミド繊維等により構成されているが、帯状部材３０をピアノ線等を束ねた構成にしてもよいし、板金等により帯状に形成してもよい。すなわち、帯状部材３０が、帯状部材３０の長手方向における引張強度が比較的大きく構成されていればよい。   Moreover, in 1st Embodiment and 2nd Embodiment, although the strip | belt-shaped member 30 is comprised with the aramid fiber etc., you may make the strip | belt-shaped member 30 the structure which bundled the piano wire etc., sheet metal etc. May be formed into a belt shape. In other words, it is only necessary that the belt-shaped member 30 has a relatively large tensile strength in the longitudinal direction of the belt-shaped member 30.

さらに、第１の実施の形態及び第２の実施の形態における帯状部材３０を中空の帯状に形成してよい。   Furthermore, you may form the strip | belt-shaped member 30 in 1st Embodiment and 2nd Embodiment in a hollow strip | belt shape.

また、第１の実施の形態では、帯状部材３０の他端部３４がフロントバンパカバー１８に結合されており、第２の実施の形態では、帯状部材３０の他端部３４がフェンダライナ２４に結合されているが、他端部３４が結合される部材（車両用構成部材）はこれに限らない。この点について第１の実施の形態を用いて説明すると、例えば他端部３４をフェンダライナ２４やアンダーカバー（図示省略）等に結合してもよい。すなわち、車両１０の微小ラップ衝突時に帯状部材３０が衝突体Ｄと前輪２０とによって挟み込まれるように他端部が車両１０を構成する車両用構成部材に結合されていればよい。さらに、フェンダライナ２４に他端部３４を結合する場合には、フェンダライナ２４と帯状部材３０とを一体に形成してもよい。   In the first embodiment, the other end 34 of the belt-like member 30 is coupled to the front bumper cover 18, and in the second embodiment, the other end 34 of the belt-like member 30 is connected to the fender liner 24. Although it couple | bonds, the member (constituent member for vehicles) to which the other end part 34 is couple | bonded is not restricted to this. This will be described with reference to the first embodiment. For example, the other end 34 may be coupled to the fender liner 24, an under cover (not shown), or the like. That is, it is only necessary that the other end is coupled to the vehicle constituent member constituting the vehicle 10 so that the belt-like member 30 is sandwiched between the collision body D and the front wheel 20 at the time of the minute lap collision of the vehicle 10. Furthermore, when the other end portion 34 is coupled to the fender liner 24, the fender liner 24 and the band-shaped member 30 may be integrally formed.

さらに、第１の実施の形態及び第２の実施の形態では、サイドメンバ１２の前端部とバンパＲ／Ｆ１６との間にクラッシュボックス１４が設けられているが、クラッシュボックス１４を省略してサイドメンバ１２の前端部をバンパＲ／Ｆ１６に結合してもよい。   Furthermore, in the first embodiment and the second embodiment, the crash box 14 is provided between the front end portion of the side member 12 and the bumper R / F 16. The front end of the member 12 may be coupled to the bumper R / F 16.
