Abstract

PROBLEM TO BE SOLVED: To provide an upper cross member mounting structure that is able to securely protect a pedestrian by a simple configuration.SOLUTION: In the vicinity of an upper cross member UCM on an axial line L1, the upper cross member UCM is supported by a lower support surface 103 and a flange surface FE3 of a fender apron FE. Accordingly, deformation in a case where force F is applied toward the rear of the vehicle can be reduced. That is, the upper cross member UCM and a lower absorber LAB are able to prevent a lower leg of a pedestrian involved in a collision from being forced toward the rear of the vehicle. In the vicinity of the upper cross member UCM on an axial line L3, the upper cross member UCM is supported by a lower support surface 103 not supported in air. Accordingly, force can be absorbed by the upper cross member UCM and an upper cross member mounting device 100. As a result, in the event that a lower leg of a pedestrian involved in a collision is forced toward the rear of the vehicle, an amount of bend of the lower leg can be decreased.SELECTED DRAWING: Figure 2

Description

本発明は、アッパクロスメンバ取り付け構造に関し、特に、簡易な構成で、確実に歩行者を保護できるものに関する。   The present invention relates to an upper cross member mounting structure, and particularly to a structure that can reliably protect a pedestrian with a simple configuration.

従来の歩行者衝突時に歩行者を保護する車体Ｓの前部の構造について、図４を用いて説明する。車体Ｓの前部の構造は、バンパリインフォースメント１８がバンパカバー２２によって被覆されたフロントバンパ１６を備えている。バンパカバー２２の下端よりも下方に突出することなく配置された可動部材３２は、通常は荷重支持部３８を初期衝突する部位であるバンパカバー２２の中間部２２Ａよりも後方に位置させ、バンパカバー２２への歩行者Ｐの衝突によって、ヒンジ部３２Ａ廻りに回動して荷重支持部３８を中間部２２Ａに対し相対的に前方へ移動し、該荷重支持部３８によってバンパリインフォースメント１８の下方で衝突荷重の一部を支持することで、荷重を受ける面積を上下方向に増大する。これにより、歩行者との衝突時に該歩行者の膝関節に作用する荷重を緩和でき、かつ十分なアプローチアングルを確保することができる車体全部の構造を得る（以上、特許文献１参照）。   The structure of the front part of the vehicle body S that protects a pedestrian during a conventional pedestrian collision will be described with reference to FIG. The front structure of the vehicle body S includes a front bumper 16 in which a bumper reinforcement 18 is covered with a bumper cover 22. The movable member 32 arranged without projecting downward from the lower end of the bumper cover 22 usually positions the load support portion 38 behind the intermediate portion 22A of the bumper cover 22 which is a portion where the initial collision occurs. When the pedestrian P collides with the pedestrian 22, the pedestrian P rotates about the hinge portion 32 </ b> A to move the load support portion 38 relatively forward with respect to the intermediate portion 22 </ b> A. By supporting a part of the collision load, the area receiving the load is increased in the vertical direction. Thereby, the structure of the whole vehicle body which can relieve | moderate the load which acts on this pedestrian's knee joint at the time of a collision with a pedestrian, and can ensure a sufficient approach angle is obtained (refer patent document 1 above).

特開２００４−２６８８２６号公報JP 2004-268826 A

前述の車体Ｓの前部の構造には、以下に示すような改善すべき点がある。車体Ｓの前部の構造では、ヒンジ構造の可動部材をバンパリインフォースメントに設ける必要があり、構成が複雑で、部品点数が多くなり、コストがかかる、という改善すべき点がある。   The structure of the front portion of the vehicle body S has the following points to be improved. In the structure of the front part of the vehicle body S, it is necessary to provide a hinge-shaped movable member in the bumper reinforcement, and there is a point to be improved that the configuration is complicated, the number of parts is increased, and the cost is increased.

このため、衝突時の歩行者保護のためのロワアブソーバを、車体下部の所定の位置に配置することが考えられる。この構造では、ロワアブソーバを設置していない領域、特に、両端のロワアブソーバより車両外側においては、バンパ等が片持ち梁として機能するため、下腿部を支持できず、下腿部が車両後方に向かって振り込み、下腿部に過度な曲げが生じないような歩行者保護構造とする必要がある。   For this reason, it is conceivable to arrange a lower absorber for protecting pedestrians at the time of a collision at a predetermined position below the vehicle body. In this structure, the bumper etc. function as a cantilever beam in the area where the lower absorber is not installed, especially outside the lower absorber at both ends, so the lower leg cannot be supported and the lower leg is behind the vehicle. It is necessary to make a pedestrian protection structure that does not cause excessive bending in the lower leg.

そこで、本発明は、簡易な構成で、確実に歩行者を保護できるアッパクロスメンバ取り付け構造を提供することを目的とする。   Accordingly, an object of the present invention is to provide an upper cross member mounting structure that can protect a pedestrian with certainty with a simple configuration.

本発明における課題を解決するための手段及び発明の効果を以下に示す。   Means for solving the problems in the present invention and the effects of the invention will be described below.

本発明に係るアッパクロスメンバ取り付け構造は、サイドメンバ、前記サイドメンバの上方から車両外側に向かう車両前方側の端面に、車両左右方向に沿ったフランジ面を有するフェンダエプロン、前記フェンダエプロンの前記フランジ面に接続されるアッパクロスメンバを有する自動車において、前記アッパクロスメンバと前記エプロンとの間にアッパクロスメンバ取り付け装置を配置するアッパクロスメンバ取り付け構造であって、前記アッパクロスメンバ取り付け装置は、前記アッパクロスメンバに接するアッパクロスメンバ取り付け面、少なくとも、前記アッパクロスメンバ取り付け面の車両下側の端縁沿った、前記フェンダエプロンの前記フランジ面の車両前方への投影領域において、前記アッパクロスメンバ取り付け面の前記車両下側の端縁から、前記フェンダエプロンの前記フランジ面まで、車両後方に向かって形成される下側支持面、前記アッパクロスメンバ取り付け面の車両上側の端縁において、前記フェンダエプロンの前記フランジ面以外の車両前方への投影領域において、前記アッパクロスメンバ取り付け面の前記車両上側の端縁から、前記フェンダエプロンの前記フランジまで、車両後方に向かって形成される上側支持面であって、前記フェンダエプロンの前記端縁に対して車両外側にのみ形成される上側支持面、を有する。   The upper cross member mounting structure according to the present invention includes a side member, a fender apron having a flange surface along the vehicle left-right direction on an end surface of the vehicle front side from above the side member toward the vehicle outer side, and the flange of the fender apron. In an automobile having an upper cross member connected to a surface, an upper cross member mounting structure in which an upper cross member mounting device is disposed between the upper cross member and the apron, wherein the upper cross member mounting device includes: The upper cross member mounting surface in a projection area of the flange surface of the fender apron to the front of the vehicle along the vehicle lower side edge of the upper cross member mounting surface at least in contact with the upper cross member. Plane of said car From the lower edge to the flange surface of the fender apron, the lower support surface formed toward the rear of the vehicle, and the upper edge of the upper cross member mounting surface on the vehicle upper edge, the flange surface of the fender apron The upper support surface formed toward the rear of the vehicle from the vehicle upper end edge of the upper cross member mounting surface to the flange of the fender apron in a vehicle projection area other than An upper support surface formed only on the vehicle outer side with respect to the edge of the apron.

これにより、サイドメンバに対して車両上方のアッパクロスメンバ付近では、アッパクロスメンバは、下側支持面、及び、フェンダエプロンのフランジ面によって支えられている。このため、車両後方側へ力Ｆを受けた際の変形を低減することができる。つまり、アッパクロスメンバ取り付け装置によってアッパクロスメンバを支持するため、結果として、アッパクロスメンバによって、衝突した歩行者の下腿部が車両後方に向かって振り込み、下腿部に過度な曲げが生ずることを防止することができる。   Accordingly, in the vicinity of the upper cross member above the vehicle with respect to the side member, the upper cross member is supported by the lower support surface and the flange surface of the fender apron. For this reason, the deformation | transformation at the time of receiving the force F to the vehicle rear side can be reduced. In other words, since the upper cross member is supported by the upper cross member mounting device, as a result, the lower crus of the colliding pedestrian is swung toward the rear of the vehicle by the upper cross member, resulting in excessive bending of the crus. Can be prevented.

また、サイドメンバに対して車両外側のアッパクロスメンバ付近では、アッパクロスメンバは、空中で支持されていない下側支持面によって支えられている。このため、車両後方側へ力Ｆを受けた際の変形を低減することができず、大きく変形する。つまり、アッパクロスメンバ、及び、アッパクロスメンバ取り付け装置によって、力を吸収でき、結果として、衝突した歩行者の下腿部が車両後方に向かって振り込み、下腿部に生ずる曲げの量を低減することができる。   Further, in the vicinity of the upper cross member outside the vehicle with respect to the side member, the upper cross member is supported by a lower support surface that is not supported in the air. For this reason, a deformation | transformation at the time of receiving the force F to the vehicle rear side cannot be reduced, but deform | transforms large. In other words, the upper cross member and the upper cross member attaching device can absorb the force, and as a result, the collided pedestrian's lower leg part is swung toward the rear of the vehicle, and the amount of bending generated in the lower leg part is reduced. be able to.

以下、本発明の実施例について、図面を参照しながら詳細に説明していく。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

本発明に係るアッパクロスメンバ取り付け構造の一実施形態であるアッパクロスメンバ取り付け構造２００について図面を用いて説明する。   An upper cross member mounting structure 200 as an embodiment of the upper cross member mounting structure according to the present invention will be described with reference to the drawings.

１．自動車Ｃの構造
アッパクロスメンバ取り付け構造２００を配置する自動車Ｃの構造について、図１を用いて説明する。図１に、フロントフェンダ、前輪、前輪の駆動構造等を取り除いた自動車ＣのフードＦＤ内を正面から見た状態を示す。自動車Ｃは、サイドメンバＳＭ、フェンダエプロンＦＥ、アッパクロスメンバＵＣＭ、を有している。なお、自動車Ｃは、フード内に、その他、ラジエータＲＧ、ロワクロスメンバＬＣＭ、ロワアブソーバＬＡＢ、オフセット衝突対策のリインフォースＲＦ等を有している。なお、リインフォースＲＦは、運転席側の前方にのみ配置されている。 1. Structure of Car C The structure of the car C in which the upper cross member mounting structure 200 is arranged will be described with reference to FIG. FIG. 1 shows a state in which the inside of the hood FD of the automobile C from which the front fender, the front wheels, the front wheel drive structure, and the like are removed is viewed from the front. The automobile C has a side member SM, a fender apron FE, and an upper cross member UCM. In addition, the automobile C includes a radiator RG, a lower cross member LCM, a lower absorber LAB, a reinforcement RF for offset collision countermeasures, and the like in the hood. Note that the reinforcement RF is disposed only in front of the driver's seat.

サイドメンバＳＭは、車両の下方に、車両の前後方向に沿って配置される。なお、サイドメンバＳＭは、車両の左右それぞれに、１つずつ形成される。フェンダエプロンＦＥは、タイヤハウスとフードＦＤ内空間とを隔離する部材である。フェンダエプロンＦＥは、サイドメンバＳＭの上方から車両外側に向かう車両前方側の端縁ＦＥ１に、車両前方方向に沿った法線を有するフランジ面ＦＥ３を有している（図２Ａ参照）。なお、フェンダエプロンＦＥの端縁ＦＥ１は、車両前方から見て、車両下方から車両上方外側に向かう円弧形状を有している。   The side member SM is arranged below the vehicle along the front-rear direction of the vehicle. One side member SM is formed on each of the left and right sides of the vehicle. The fender apron FE is a member that separates the tire house from the space inside the hood FD. The fender apron FE has a flange surface FE3 having a normal line along the vehicle front direction at an edge FE1 on the vehicle front side from the upper side of the side member SM toward the vehicle outer side (see FIG. 2A). Note that the edge FE1 of the fender apron FE has an arc shape from the vehicle lower side toward the vehicle upper outer side as viewed from the front of the vehicle.

アッパクロスメンバＵＣＭは、フェンダエプロンＦＥに接続される。アッパクロスメンバＵＣＭは、左右に位置するフェンダエプロンＦＥを懸架するように配置される。   The upper cross member UCM is connected to the fender apron FE. The upper cross member UCM is arranged to suspend the fender apron FE located on the left and right.

アッパクロスメンバ取り付け装置１００は、アッパクロスメンバＵＣＭとフェンダエプロンＦＥとの間に配置される。つまり、アッパクロスメンバ取り付け装置１００は、自身を介してアッパクロスメンバＵＣＭとフェンダエプロンＦＥとを接続する接続部材である。なお、アッパクロスメンバ取り付け装置１００は、リインフォースＲＦが配置されていない助手席側の前方にのみ配置されている。このように、リインフォースＲＦが配置されている運転席側には、アッパクロスメンバ取り付け装置１００を配置せず、リインフォースＲＦが配置されていない助手席側のみアッパクロスメンバ取り付け装置１００を配置することによって、機能に応じたアッパクロスメンバ取り付け構造にできる。   The upper cross member attaching device 100 is disposed between the upper cross member UCM and the fender apron FE. That is, the upper cross member attaching apparatus 100 is a connecting member that connects the upper cross member UCM and the fender apron FE through itself. In addition, the upper cross member attachment apparatus 100 is arrange | positioned only in front of the passenger seat side where the reinforcement RF is not arrange | positioned. Thus, the upper cross member mounting device 100 is not disposed on the driver seat side where the reinforce RF is disposed, and the upper cross member mounting device 100 is disposed only on the passenger seat side where the reinforce RF is not disposed. The upper cross member mounting structure according to the function can be obtained.

２．アッパクロスメンバ取り付け構造２００
アッパクロスメンバ取り付け構造２００は、アッパクロスメンバＵＣＭの助手席側の端部に形成される。アッパクロスメンバ取り付け構造２００は、アッパクロスメンバＵＣＭとフェンダエプロンＦＥとの間にアッパクロスメンバ取り付け装置１００を配置することによって形成される。 2. Upper cross member mounting structure 200
The upper cross member mounting structure 200 is formed at the end of the upper cross member UCM on the passenger seat side. The upper cross member mounting structure 200 is formed by disposing the upper cross member mounting device 100 between the upper cross member UCM and the fender apron FE.

３．アッパクロスメンバ取り付け装置１００
アッパクロスメンバ取り付け装置１００の構造について、図２を用いて説明する。なお、図２Ａにアッパクロスメンバ取り付け装置１００の正面図を、図２Ｂに同底面図を、図２Ｃに同平面図を、それぞれ示す。アッパクロスメンバ取り付け装置１００は、アッパクロスメンバ取り付け面１０１（図２Ａ参照）、下側支持面１０３（図２Ｂ参照）、及び、上側支持面１０５（図２Ｃ参照）を有している。 3. Upper cross member attaching device 100
The structure of the upper cross member attaching apparatus 100 will be described with reference to FIG. 2A is a front view of the upper cross member mounting apparatus 100, FIG. 2B is a bottom view thereof, and FIG. 2C is a plan view thereof. The upper cross member mounting apparatus 100 includes an upper cross member mounting surface 101 (see FIG. 2A), a lower support surface 103 (see FIG. 2B), and an upper support surface 105 (see FIG. 2C).

アッパクロスメンバ取り付け装置１００は、アッパクロスメンバ取り付け面１０１を中心に、下側支持面１０３、及び、上側支持面１０５によって形成されるコの字形状を有している。なお、下側支持面１０３、及び、上側支持面１０５のアッパクロスメンバ取り付け面１０１とは異なる端縁には、自身をフェンダエプロンＦＥのフランジ面ＦＥ３に固定するための固定フランジＦ１０３、Ｆ１０５が、それぞれ形成されている。   The upper cross member mounting apparatus 100 has a U-shape formed by a lower support surface 103 and an upper support surface 105 with the upper cross member mounting surface 101 as a center. In addition, fixing flanges F103 and F105 for fixing itself to the flange surface FE3 of the fender apron FE are provided at the edge of the lower support surface 103 and the upper support surface 105 different from the upper cross member mounting surface 101. Each is formed.

アッパクロスメンバ取り付け面１０１は、アッパクロスメンバＵＣＭに接する。図２Ｂに示すように、下側支持面１０３は、少なくとも、アッパクロスメンバ取り付け面１０１の車両下側の端縁Ｌ１０１沿った、フェンダエプロンＦＥのフランジ面ＦＥ３の車両前方への投影領域Ｓ１０３において、アッパクロスメンバ取り付け面１０１の車両下側の端縁Ｌ１０１から、フェンダエプロンＦＥのフランジ面ＦＥ３まで、車両後方に向かって形成される。   The upper cross member mounting surface 101 is in contact with the upper cross member UCM. As shown in FIG. 2B, the lower support surface 103 is at least in a projection area S103 of the flange surface FE3 of the fender apron FE on the front side of the vehicle along the lower edge L101 of the upper cross member mounting surface 101. The upper cross member mounting surface 101 is formed from the vehicle lower end edge L101 to the flange surface FE3 of the fender apron FE toward the rear of the vehicle.

上側支持面１０５は、アッパクロスメンバ取り付け面１０１の車両上側の端縁Ｕ１０１において、フェンダエプロンＦＥのフランジ端面ＦＥ３以外の車両前方への投影領域Ｓ１０５において、アッパクロスメンバ取り付け面１０１の車両上側の端縁Ｕ１０１から、フェンダエプロンＦＥのフランジ面ＦＥ３まで、車両後方に向かって形成される。つまり、上側支持面１０５は、アッパクロスメンバ取り付け面１０１の車両上側の端縁Ｕ１０１において、フェンダエプロンＦＥの端縁ＦＥ１に対して車両外側にのみ形成される。   The upper support surface 105 is an end of the upper cross member mounting surface 101 on the upper side of the upper cross member mounting surface 101 in the projection area S105 forward of the vehicle other than the flange end surface FE3 of the fender apron FE. From the edge U101 to the flange surface FE3 of the fender apron FE, it is formed toward the rear of the vehicle. That is, the upper support surface 105 is formed only on the vehicle outer side with respect to the edge FE1 of the fender apron FE at the vehicle upper edge U101 of the upper cross member mounting surface 101.

図２に示すＸ−Ｘ断面を図３Ａに、同Ｙ−Ｙ断面を図３Ｂに、それぞれ示す。なお、図２に示すＸ−Ｘ断面は図１における軸線Ｌ１に沿った断面に相当し、Ｙ−Ｙ断面は図１における軸線Ｌ３に沿った断面に相当する。ここで、軸線Ｌ１は、ほぼサイドメンバＳＭの上方に沿った線上を示し、軸線Ｌ３は、サイドメンバＳＭから車両外側によった位置の上方に沿った線上を示す。   The XX cross section shown in FIG. 2 is shown in FIG. 3A, and the YY cross section is shown in FIG. 3B. 2 corresponds to the cross section along the axis L1 in FIG. 1, and the YY cross section corresponds to the cross section along the axis L3 in FIG. Here, the axis L1 indicates a line substantially along the upper side of the side member SM, and the axis L3 indicates a line along the upper side of the position according to the vehicle outer side from the side member SM.

図３Ａに示すように、軸線Ｌ１上のアッパクロスメンバＵＣＭ付近においては、アッパクロスメンバＵＣＭの車両後方側にはフェンダエプロンＦＥのフランジ面ＦＥ３に支えられた下側支持面１０３が存在する。つまり、アッパクロスメンバＵＣＭは、下側支持面１０３、及び、フェンダエプロンＦＥのフランジ面ＦＥ３によって支えられている。このため、図３Ｃに示すように、車両後方側へ力Ｆを受けた際の変形を低減することができる。つまり、軸線Ｌ３上のアッパクロスメンバＵＣＭ付近において車両後方側へ力Ｆを受けたとしても、アッパクロスメンバ取り付け装置１００によってアッパクロスメンバＵＣＭを支持するため、結果として、アッパクロスメンバ取り付け構造２００では、アッパクロスメンバＵＣＭ、及び、ロワアブソーバＬＡＢ（図１参照）によって、衝突した歩行者の下腿部が車両後方に向かって振り込まれることを防止することができる。   As shown in FIG. 3A, in the vicinity of the upper cross member UCM on the axis L1, a lower support surface 103 supported by the flange surface FE3 of the fender apron FE exists on the vehicle rear side of the upper cross member UCM. That is, the upper cross member UCM is supported by the lower support surface 103 and the flange surface FE3 of the fender apron FE. For this reason, as shown to FIG. 3C, the deformation | transformation at the time of receiving force F to the vehicle rear side can be reduced. In other words, even if a force F is applied to the vehicle rear side in the vicinity of the upper cross member UCM on the axis L3, the upper cross member UCM is supported by the upper cross member mounting device 100. As a result, in the upper cross member mounting structure 200, The upper cross member UCM and the lower absorber LAB (see FIG. 1) can prevent the collided lower leg of the pedestrian from being swung toward the rear of the vehicle.

一方、図３Ｂに示すように、軸線Ｌ３上のアッパクロスメンバＵＣＭ付近においては、車両後方側では何ものにも支えられない下側支持面１０３が存在する。つまり、アッパクロスメンバＵＣＭは、空中で支持されていない下側支持面１０３によって支えられている。このため、図３Ｄに示すように、車両後方側へ力Ｆを受けた際の変形を低減することができず、大きく変形する。つまり、軸線Ｌ３上のアッパクロスメンバＵＣＭ付近において車両後方側へ力Ｆを受けたとしても、アッパクロスメンバＵＣＭ、及び、アッパクロスメンバ取り付け装置１００によって、力を吸収でき、結果として、アッパクロスメンバ取り付け構造２００では、衝突した歩行者の下腿部が車両後方に向かって振り込み、下腿部に生ずる曲げの量を低減することができる。   On the other hand, as shown in FIG. 3B, in the vicinity of the upper cross member UCM on the axis L3, there is a lower support surface 103 that is not supported by anything on the vehicle rear side. That is, the upper cross member UCM is supported by the lower support surface 103 that is not supported in the air. For this reason, as shown to FIG. 3D, the deformation | transformation at the time of receiving the force F to the vehicle rear side cannot be reduced, but deform | transforms large. In other words, even if the force F is applied to the vehicle rear side in the vicinity of the upper cross member UCM on the axis L3, the force can be absorbed by the upper cross member UCM and the upper cross member attaching device 100, and as a result, the upper cross member In the attachment structure 200, the lower leg part of the pedestrian who collided is transferred toward the rear of the vehicle, and the amount of bending generated in the lower leg part can be reduced.
