Description

本発明は、バンパリインフォースメントに関する。特に、自動車の前部または後部に装備されるバンパ構造の芯材として配設されるバンパリインフォースメントに関する。   The present invention relates to bumper reinforcement. In particular, the present invention relates to bumper reinforcement disposed as a core of a bumper structure mounted on the front or rear of a car.

自動車車体の前部または後部には、車両衝突時における衝突荷重を受けるバンパ構造が備えられる。バンパ構造には芯材としてのバンパリインフォースメントが備えられる。バンパリインフォースメントは自動車車体の幅方向に長尺形状として配設されており、自動車車体の幅方向の両端部位置で自動車車体のフレーム部材にバンパ支持構造で連結されて支持される。バンパ支持構造は、通常、車両衝突時のエネルギー吸収作用が行われるクラッシュボックスが用いられる。なお、クラッシュボックスが用いられない場合は、サイドメンバが接続結合されて、エネルギー吸収作用が行われる。   A bumper structure is provided at the front or rear of the vehicle body to receive an impact load at the time of a vehicle collision. The bumper structure is provided with bumper reinforcement as a core material. The bumper reinforcement is disposed in the width direction of the vehicle body as a long shape, and is supported by being connected to the frame member of the vehicle body by the bumper support structure at both end positions in the width direction of the vehicle body. As the bumper support structure, a crash box is usually used in which energy absorption is performed in the event of a vehicle collision. When the crash box is not used, the side members are connected and coupled to perform energy absorption.

バンパリインフォースメントの構成形態は、各種形態がある。例えば、バンパリインフォースメントは、本体部材と補強部材とからなる形態がある（下記特許文献１参照）。この場合、本体部材は断面ハット型形状の主体部材と、この主体部材の開口側に当該開口部を閉鎖するように配設されて、当該本体部材を閉じ断面形状とする面状板部材とからなる。   There are various forms of configuration of bumper reinforcement. For example, bumper reinforcement has a form which consists of a main-body member and a reinforcement member (refer the following patent documents 1). In this case, the main body member is provided from the main body member having a hat-shaped cross section, and the planar plate member which is disposed on the opening side of the main body member to close the opening and closes the main body member. Become.

補強部材は断面台形状であり、閉じ断面形状の本体部材の内部に配設される。補強部材の台形状は、本体部材の面状板部材に面して配設される前部面板部位と、主体部材の後側面板部位に面して配設される後部面板部位と、両部位を繋ぐ上傾斜面板部位及び下傾斜面板部位とから構成される。そして、上傾斜面板部位及び下傾斜面板部位の前部面板部位寄りの位置には、主体部材の上側面板部位及び下側面板部位に面して上支持板部位及び下支持板部位が形成されている。この上支持板部位及び下支持板部位が形成される位置は、ハット型断面形状の主体部材における開口側の上側面板部位及び下側面板部位に面した位置である。   The reinforcing member is trapezoidal in cross section and disposed inside the body member in a closed cross sectional shape. The trapezoidal shape of the reinforcing member is a front face plate portion disposed facing the planar plate member of the main body member, a rear face plate portion disposed facing the rear side plate portion of the main member, and both portions The upper inclined plane plate portion and the lower inclined plane plate portion connecting the two. The upper support plate portion and the lower support plate portion are formed facing the upper side plate portion and the lower side plate portion of the main member at positions near the front side plate portion of the upper inclined plane plate portion and the lower inclined plane plate portion There is. The positions at which the upper support plate portion and the lower support plate portion are formed are the positions facing the upper side plate portion and the lower side plate portion on the opening side of the main member having the hat-shaped cross section.

上述した形態のバンパリインフォースメントは、本体部材の面状板部材側が衝突荷重の入力側となるように配置される。これによりバンパリインフォースメントに衝突荷重が入力した際に、補強部材の補強作用によって本体部材の断面崩れの防止ないし抑制を図り、バンパリインフォースメントにより受ける荷重の増大を図っている。   The bumper reinforcement of the above-described embodiment is disposed such that the planar plate member side of the main body member is the collision load input side. As a result, when a collision load is input to the bumper reinforcement, the reinforcement action of the reinforcing member prevents or suppresses the collapse of the cross section of the main body member, thereby increasing the load received by the bumper reinforcement.

すなわち、補強部材の上支持板部位及び下支持板部位が、衝突荷重が加わった際、主体部材における上側面板部位及び下側面板部位の内方への変形移動を押えて、断面崩れの防止ないし抑制を図るようにしている。   That is, when a collision load is applied to the upper support plate portion and the lower support plate portion of the reinforcing member, the inward deformation movement of the upper side plate portion and the lower side plate portion in the main member is suppressed to prevent the cross section collapse I try to control.

なお、補強部材は、２分割して構成する形態も提案されている（下記特許文献２、図５、図９参照）。この補強部材の分割は、補強部材の前部面板部位と後部面板面部位とで行い、上側補強体と下側補強体とからなる補強部材の構成としている。   In addition, the form which divides and comprises a reinforcement member and is comprised is also proposed (refer the following patent document 2, FIG. 5, FIG. 9). The division of the reinforcing member is performed at the front surface plate portion and the rear surface plate surface portion of the reinforcing member, and is configured as a reinforcing member including the upper reinforcing body and the lower reinforcing body.

ところで、上述した閉じ断面形状の本体部材の内部に補強部材を配設する形態のバンパリインフォースメントにあっては、補強部材は長尺状の本体部材の中央部位置に配設される。そして、補強部材は本体部材の強度を補強する観点から補強部材全体の強度は、同じ強度とされている。そのため、衝突荷重が加わる本体部材の面状板部材と、補強部材の前部面板部位との重ね合わせ箇所の強度（剛性）が必要以上に強くなることがある。この衝突荷重が加わる重ね合わせ箇所の強度（剛性）が強すぎると、衝突荷重が加わる箇所に応力集中が生じ、当該箇所で座屈を生じる。その結果、当該箇所が折損して、バンパリインフォースメントを通じて衝突荷重がクラッシュボックスに効果的に伝達されないという問題を生じることがある。   By the way, in the bumper reinforcement in which the reinforcing member is disposed inside the closed cross-section main body member described above, the reinforcing member is disposed at the central position of the elongated main body member. Further, in order to reinforce the strength of the main body member, the strength of the entire reinforcing member is the same. Therefore, the strength (rigidity) of the overlapping portion of the planar plate member of the main body member to which the collision load is applied and the front surface plate portion of the reinforcing member may become stronger than necessary. If the strength (stiffness) of the overlapping portion to which the collision load is applied is too strong, stress concentration occurs at the portion to which the collision load is applied, and buckling occurs at the portion. As a result, the portion may be broken, which may cause a problem that the collision load is not effectively transmitted to the crash box through the bumper reinforcement.

また、補強部材には、断面ハット型の主体部材における開口側の上側面板部位及び下側面板部位に面して配設される、上支持板部位及び下支持板部位が設けられている。これにより、衝突荷重が加わった際、主体部材における上側面板部位及び下側面板部位の内方への変形移動を防止ないし抑制して、バンパリインフォースメントの断面崩れを防止ないし抑制するようにしている。しかし、補強部材における支持板部位の強度（剛性）が弱いと、主体部材における上側面板部位及び下側面板部位の内方への変形移動を充分に防止ないし抑制することができなくて、バンパリインフォースメントの断面崩れを生じることがある。   Further, the reinforcing member is provided with an upper support plate portion and a lower support plate portion disposed facing the upper side plate portion and the lower side plate portion on the opening side of the main body member having a hat-shaped cross section. Thereby, when a collision load is applied, the inward deformation movement of the upper side surface plate portion and the lower side surface plate portion in the main body member is prevented or suppressed, and the collapse of the bumper reinforcement is prevented or suppressed. . However, if the strength (stiffness) of the support plate portion in the reinforcing member is weak, the inward deformation movement of the upper side plate portion and the lower side plate portion in the main member can not be sufficiently prevented or suppressed. It may cause the cross section of the mentor to collapse.

以上のことから、本発明者は、補強部材の強度（剛性）の特性として、衝突荷重が加わる前部面板部位は相対的に弱い強度（剛性）とし、断面崩れを防止ないし抑制する支持板部位は相対的に強い強度（剛性）とすることが必要とされることに到達した。   From the above, the inventor of the present invention, as a characteristic of the strength (rigidity) of the reinforcing member, makes the front face plate part to which the collision load is applied relatively weak strength (rigidity) and prevents or suppresses the cross section collapse. Has reached what is required to be relatively strong (rigid).

本発明は上述した点に鑑みて創案されたものであって、本発明が解決しようとする課題は、次の２点にある。   The present invention has been made in view of the above-mentioned points, and the problems to be solved by the present invention are the following two points.

第１点は、補強部材を支持板部位で分割構成することにより、補強部材の衝突荷重が加わる前部面板部位の強度（剛性）を、他の部位の強度より相対的に弱くして、応力集中及びそれに伴う座屈が生じるのを防止ないし抑制することにある。その結果、バンパリインフォースメントの折損を防止ないし抑制する。   The first point is that the strength (stiffness) of the front face plate portion to which the collision load of the reinforcement member is applied is made relatively weaker than the strength of other portions by dividing the reinforcing member at the support plate portion, The purpose is to prevent or suppress the concentration and the resulting buckling. As a result, breakage of bumper reinforcement is prevented or suppressed.

第２点は、補強部材を支持板部位で分割構成し、その分割構成箇所を重ね合わせ構成とすることにより、当該支持板部位の強度（剛性）を、他の部位の強度より相対的に強くして、主体部材における上側面板部位及び下側面板部位の内方への変形移動を防止ないし抑制し、バンパリインフォースメントの断面崩れを防止ないし抑制することにある。   The second point is that the reinforcing member is divided at the support plate portion, and the divided configuration portions are overlapped to form the strength (rigidity) of the support plate portion relatively stronger than the strengths of the other portions. Thus, the inward deformation movement of the upper side plate portion and the lower side plate portion in the main component is prevented or suppressed, and the collapse of the bumper reinforcement is prevented or suppressed.

先ず、図１は自動車におけるバンパ構造１０の配置位置を示す。バンパ構造１０は、通常、自動車車体１２の前部と後部に自動車車体１２に対して車幅方向に配置される。図１において、自動車車体１２の前方を矢印Ｆｒで示し、後方を矢印Ｒｒで示した。自動車の車室は自動車車体１２の位置に形成される。バンパ構造１０は、バンパリインフォースメント１４と、バンパ被覆部材１６と、バンパ支持構造１８とから成っている。バンパリインフォースメント１４はバンパ構造１０の強度上の芯材として配設される。バンパ被覆部材１６はバンパリインフォースメント１４の前面を被覆するように配設される。バンパ被覆部材１６はバンパ構造１０の最外面に配設され、見栄えを考慮した構成とされている。通常、意匠の成形に適する樹脂製で形成される。   First, FIG. 1 shows the arrangement position of the bumper structure 10 in a car. The bumper structure 10 is generally disposed in the vehicle width direction with respect to the vehicle body 12 at the front and rear of the vehicle body 12. In FIG. 1, the front of the vehicle body 12 is indicated by an arrow Fr, and the rear is indicated by an arrow Rr. The compartment of the car is formed at the position of the car body 12. The bumper structure 10 comprises a bumper reinforcement 14, a bumper covering member 16 and a bumper support structure 18. The bumper reinforcement 14 is disposed as a core of the bumper structure 10 in terms of strength. The bumper covering member 16 is disposed to cover the front surface of the bumper reinforcement 14. The bumper covering member 16 is disposed on the outermost surface of the bumper structure 10 and is configured in consideration of the appearance. Usually, it is made of a resin suitable for molding a design.

バンパ支持構造１８は、バンパリインフォースメント１４の長手方向（自動車車体１２で見て幅方向）の両端部の位置で自動車車体１２のフレーム部材（不図示）とバンパリインフォースメント１４との間に配設される。そして、このバンパ支持構造１８によりバンパリインフォースメント１４で受ける衝突荷重を自動車車体１２に伝えて受ける。バンパ支持構造１８は本実施形態ではクラッシュボックス（Ｃ／Ｂ）及びサイドメンバと称される衝突エネルギーを吸収することができる構成部材で形成されている。   The bumper support structure 18 is disposed between the frame member (not shown) of the car body 12 and the bumper reinforcement 14 at positions on both ends of the bumper reinforcement 14 in the longitudinal direction (the width direction as viewed from the car body 12). Be done. Then, the collision load received by the bumper reinforcement 14 is transmitted to the vehicle body 12 and received by the bumper support structure 18. The bumper support structure 18 is formed of a component capable of absorbing collision energy, which is referred to as a crash box (C / B) and a side member in the present embodiment.

なお、以後に説明する実施形態は、自動車車体１２の前部に配設されるバンパリインフォースメント１４の場合を例にして説明する。   In the embodiment described below, the case of bumper reinforcement 14 disposed at the front of vehicle body 12 will be described as an example.

本実施形態のバンパ構造１０は、上述した配置構成であることにより、自動車の正面衝突によりバンパ構造１０の中央位置に作用する衝突荷重Ｆは、次のように受けられる。先ず、バンパ被覆部材で受けて、これをバンパリインフォースメント１４で支える。そして、バンパリインフォースメント１４に作用した荷重は、バンパリインフォースメント１４の両端部に配設されたバンパ支持構造１８としてのクラッシュボックス（Ｃ／Ｂ）を介して自動車車体１２により受けられる。この際、クラッシュボックス（Ｃ／Ｂ）が衝突エネルギーを吸収する。   The bumper structure 10 of the present embodiment having the above-described arrangement configuration receives the collision load F acting on the central position of the bumper structure 10 due to the frontal collision of the vehicle as follows. First, it is received by the bumper covering member and supported by the bumper reinforcement 14. The load acting on the bumper reinforcement 14 is received by the vehicle body 12 through a crash box (C / B) as the bumper support structure 18 disposed at both ends of the bumper reinforcement 14. At this time, the crash box (C / B) absorbs the collision energy.

以下に、バンパリインフォースメント１４の各実施形態を説明するが、予め、各実施形態に共通する構成を説明する。共通する構成は図２及び図３に示される。なお、断面形状の共通構成は図４に示す第１実施形態を用いて説明する。   Hereinafter, each embodiment of the bumper reinforcement 14 will be described, but a configuration common to each embodiment will be described in advance. A common configuration is shown in FIGS. 2 and 3. The common configuration of the cross-sectional shape will be described using the first embodiment shown in FIG.

バンパリインフォースメント１４は、図４の断面図に示されるように、本体部材２０と補強部材３０とから構成される。本体部材２０はハット型断面形状の主体部材２２と面状板部材２４とからなる。面状板部材２４は断面ハット型形状の主体部材２２の開口部を閉鎖するように配設されて、当該本体部材２０を閉じ断面形状の構成とする。補強部材３０は断面台形の枠状の形状であり、閉じ断面形状の本体部材２０の内部に配設される。そして、本実施形態のバンパリインフォースメント１４は、面状板部材２４側に衝突荷重Ｆが入力するように配設される。   The bumper reinforcement 14 is comprised of a body member 20 and a reinforcing member 30, as shown in the cross-sectional view of FIG. The main body member 20 is composed of a main body member 22 having a hat-shaped cross section and a planar plate member 24. The planar plate member 24 is disposed so as to close the opening of the main body member 22 having a hat-shaped cross section, and the main body member 20 is closed to have a cross-sectional configuration. The reinforcing member 30 has a frame shape having a trapezoidal cross section, and is disposed inside the main body member 20 having a closed cross sectional shape. And the bumper reinforcement 14 of this embodiment is arrange | positioned so that the collision load F may be input into the planar plate member 24 side.

図２はバンパリインフォースメント１４の全体形状を斜め左上方から見た斜視図である。バンパリインフォースメント１４は長手方向の両端を後退させた湾曲形状に形成されている。上述した図４は図２のIV−IV線断面図である。図３は本体部材２０を形成する主体部材２２と、その主体部材２２内に配設される補強部材３０の構成を、図２と同様に斜め左上方から見た斜視図である。図３に示されるように、補強部材３０は長尺形状のバンパリインフォースメント１４の中央部位置に配設される。なお、この補強部材３０が配設される範囲は、本実施形態では、図１に示す両端に配設される支持構造としてのクラッシュボックス１８の間の範囲内である。これによりバンパリインフォースメント１４の中央位置に入力される衝突荷重Ｆは、補強部材３０により補強されたバンパリインフォースメント１４の剛性で受けられる。   FIG. 2 is a perspective view of the entire shape of the bumper reinforcement 14 as viewed obliquely from the upper left. The bumper reinforcement 14 is formed in a curved shape in which both longitudinal ends are retracted. FIG. 4 mentioned above is a IV-IV sectional view taken on the line of FIG. FIG. 3 is a perspective view of the main body 22 forming the main body 20 and the configuration of the reinforcing member 30 disposed in the main body 22, as viewed from the upper left, as in FIG. As shown in FIG. 3, the reinforcing member 30 is disposed at the central position of the elongated bumper reinforcement 14. In the present embodiment, the range in which the reinforcing member 30 is disposed is within the range between the crash boxes 18 as support structures disposed at both ends shown in FIG. 1. The collision load F input to the central position of the bumper reinforcement 14 is thereby received by the rigidity of the bumper reinforcement 14 reinforced by the reinforcing member 30.

図４に示すように、本体部材２０を構成する断面ハット型の主体部材２２は、後側面板部位２２Ａと、上側面板部位２２Ｂと、下側面板部位２２Ｃとからなる。上側面板部位２２Ｂの開口部側には上フランジ部位２２Ｄが図４で見て上方に延設して形成されている。下側面板部位２２Ｃの開口部側には下フランジ部位２２Ｅが図４で見て下方に延設して形成されている。面状板部材２４は主体部材２２の開口側に形成された上フランジ部位２２Ｄと下フランジ部位２２Ｅに当てがわれて、溶接Ｗ１、Ｗ２により接合されて固定される。これにより、本体部材２０の閉じ断面形状が作られる。溶接は本実施形態ではスポット溶接である。以下に述べる溶接の場合も同様である。但し、スポット溶接以外の溶接箇所については、特に、注記して記す。なお、本体部材２０を構成する主体部材２２、及び面状板部材２４は、本実施形態では鋼板製とされている。   As shown in FIG. 4, the main body member 22 having a hat-shaped cross section that constitutes the main body member 20 includes a rear side plate portion 22A, an upper side plate portion 22B, and a lower side plate portion 22C. An upper flange portion 22D is formed to extend upward as viewed in FIG. 4 on the opening side of the upper side plate portion 22B. A lower flange portion 22E is formed extending downward as viewed in FIG. 4 on the opening side of the lower side plate portion 22C. The planar plate member 24 is applied to the upper flange portion 22D and the lower flange portion 22E formed on the opening side of the main body member 22, and is joined and fixed by welding W1 and W2. Thereby, the closed cross-sectional shape of the main body member 20 is created. Welding is spot welding in the present embodiment. The same applies to the case of welding described below. Note, however, that welds other than spot welds will be noted. In the present embodiment, the main member 22 and the planar plate member 24 constituting the main body member 20 are made of steel plates.

図４に示すように、断面台形の枠形状の補強部材３０は、前部面板部位３０Ａと、後部面板部位３０Ｂと、上傾斜面板部位３０Ｃと、下傾斜面板部位３０Ｄとからなる。前部面板部位３０Ａは図４で見て主体部材２２の上側面板部位２２Ｂと下側面板部位２２Ｃとの上下間隔幅一杯に配設されている。前部面板部位３０Ａは本体部材２０の面状板部材２４に面して、張り合わされた状態として配設されており、その中央部位置で、溶接Ｗ３により接合固定されて一体化されている。   As shown in FIG. 4, the frame-shaped reinforcing member 30 having a trapezoidal cross section includes a front surface plate portion 30A, a rear surface plate portion 30B, an upper inclined surface plate portion 30C, and a lower inclined surface plate portion 30D. The front face plate portion 30A is disposed to the full width of the upper and lower side plate portions 22B and 22C of the main body 22 as viewed in FIG. The front face plate portion 30A faces the planar plate member 24 of the main body member 20, and is disposed in a stuck state, and is joined and fixed by welding W3 at the central portion position and integrated.

補強部材３０の後部面板部位３０Ｂは図４で見て主体部材２２の後側面板部位２２Ａに面して配設される。そして、主体部材２２の後側面板部位２２Ａの中央部位置の一定幅のみ配設されている。すなわち、補強部材３０の後部面板部位３０Ｂは前述の主体部材２２の後側面板部位２２Ａの上下幅より短い。そのため、両部位３０Ａ、３０Ｂを繋ぐ部位である上傾斜面板部位３０Ｃと下傾斜面板部位３０Ｄは傾斜して配設される。図４で見て、上傾斜面板部位３０Ｃは左側から右側に向けて右下り傾斜として配設され、下傾斜面板部位３０Ｄは左側から右側に向けて右上がり傾斜として配設される。そして、補強部材３０の後部面板部位３０Ｂは本体部材２０の後側面板部位２２Ａと、その上下幅方向の中央位置において溶接Ｗ４にて接合固定され、一体化されている。なお、補強部材３０の材質は、本体部材２０と同様の鋼板製とされている。   The rear surface plate portion 30B of the reinforcing member 30 is disposed facing the rear side surface plate portion 22A of the main body member 22 as viewed in FIG. And only the fixed width of the central part position of back side board part 22A of main part member 22 is arranged. That is, the rear surface plate portion 30B of the reinforcing member 30 is shorter than the vertical width of the rear side surface plate portion 22A of the main component 22 described above. Therefore, the upper inclined surface plate portion 30C and the lower inclined surface plate portion 30D, which are portions connecting the two portions 30A and 30B, are disposed in an inclined manner. As seen in FIG. 4, the upper inclined surface plate portion 30C is disposed as a downward right inclination from left to right, and the lower inclined surface plate portion 30D is disposed as a right upward inclination from the left to the right. The rear surface plate portion 30B of the reinforcing member 30 is joined and fixed to the rear side surface plate portion 22A of the main body member 20 at a central position in the vertical width direction by welding W4 and integrated. The material of the reinforcing member 30 is made of the same steel plate as that of the main body member 20.

図４に示されるように、補強部材３０における上傾斜面板部位３０Ｃの前部面板部位３０Ａ寄りの位置には、本体部材２０の上側面板部位２２Ｂに面して配設される所定幅の上支持板部位３０Ｅが形成されている。同様に、下傾斜面板部位３０Ｄの前部面板部位３０Ａ寄りの位置には、本体部材２０の下側面板部位２２Ｃに面して配設される所定幅の下支持板部位３０Ｆが形成されている。この上支持板部位３０Ｅと下支持板部位３０Ｆは、本体部材２０に衝突荷重Ｆが作用したとき、それに伴い本体部材２０の上側面板部位２２Ｂと下側面板部位２２Ｃが内側方向に変形移動しようとするのを防止ないし抑制する作用をなす。   As shown in FIG. 4, a top support having a predetermined width is provided facing the upper side plate portion 22B of the main body member 20 at a position near the front face plate portion 30A of the upper inclined surface plate portion 30C in the reinforcing member 30. A plate portion 30E is formed. Similarly, a lower support plate portion 30F of a predetermined width disposed facing the lower side plate portion 22C of the main body member 20 is formed at a position near the front face plate portion 30A of the lower inclined surface plate portion 30D. . When the collision load F acts on the main body member 20, the upper support plate portion 30E and the lower support plate portion 30F attempt to deform and move the upper side plate portion 22B and the lower side plate portion 22C of the main body member 20 inward. Act to prevent or inhibit

上述した本実施形態の共通する構成において、本実施形態の特徴とする点は、補強部材３０を上支持板部位３０Ｅと下支持板部位３０Ｆで、分割して構成する点にある。その分割構成の形態には、各種の実施形態があるので、以下に説明する。なお、以下に示す各実施形態において、上述した共通する実施形態と実質的に同じ構成内容部分には同じ符号を付すことにより詳細説明を省略することがある。   In the common configuration of the present embodiment described above, the feature of the present embodiment is that the reinforcing member 30 is divided into the upper support plate portion 30E and the lower support plate portion 30F. Since there are various embodiments in the form of the division configuration, they will be described below. In each embodiment shown below, the detailed explanation may be omitted by attaching the same numerals to the composition contents part substantially the same as common embodiment mentioned above.

〔第1実施形態〕
先ず、第１実施形態を説明する。第１実施形態は図４に示される。補強部材３０は、図４の断面図に示されるように、上支持板部位３０Ｅと下支持板部位３０Ｆの箇所で分割されて、前側補強体４０と後側補強体５０とに分割されて構成される。前側補強体４０は前部面板部位３０Ａを含んで構成されており、後側補強体５０は後部面板部位３０Ｂ及び上傾斜面板部位３０Ｃ，下傾斜面板部位３０Ｄを含んで構成されている。 First Embodiment
First, the first embodiment will be described. The first embodiment is shown in FIG. The reinforcing member 30 is divided at the upper support plate portion 30E and the lower support plate portion 30F, as shown in the cross sectional view of FIG. Be done. The front reinforcing body 40 is configured to include the front face plate portion 30A, and the rear side reinforcing body 50 is configured to include the rear face plate portion 30B, the upper inclined plane plate portion 30C, and the lower inclined plane plate portion 30D.

前側補強体４０と後側補強体５０の上支持板部位３０Ｅと下支持板部位３０Ｆにおける分割構成は、いわゆる重ね合わせ構成とされている。すなわち、上支持板部位３０Ｅにおける前側補強体４０の上支持板部位３０Ｅｂと、後側補強体５０の上支持板部位３０Ｅａとが重ね合わされて配設されている。同様に、下支持板部位３０Ｆにおける前側補強体４０の下支持板部位３０Ｆｂと、後側補強体５０の下支持板部位３０Ｆａとが重ね合わされて配設されている。そして、この重ね合わせ構成は、上支持板部位３０Ｅ及び下支持板部位３０Ｆ共、前側補強体４０の上支持板部位３０Ｅｂ及び下支持板部位３０Ｆｂが外側に配設されており、後側補強体５０の上支持板部位３０Ｅａ及び下支持板部位３０Ｆａが内側に配設されている。   The divided configuration of the upper support plate portion 30E and the lower support plate portion 30F of the front side reinforcing body 40 and the rear side reinforcing body 50 is a so-called overlapping structure. That is, the upper support plate portion 30Eb of the front side reinforcing member 40 and the upper support plate portion 30Ea of the rear side reinforcing member 50 in the upper support plate portion 30E are overlapped and disposed. Similarly, the lower support plate portion 30Fb of the front reinforcement 40 at the lower support plate portion 30F and the lower support plate portion 30Fa of the rear reinforcement 50 are disposed in an overlapping manner. Further, in the overlapping configuration, the upper support plate portion 30Eb and the lower support plate portion 30Fb of the front side reinforcing member 40 are disposed on the outer side for both the upper support plate portion 30E and the lower support plate portion 30F. The upper support plate portion 30Ea and the lower support plate portion 30Fa of 50 are disposed inside.

上述した重ね合わせ構成における上支持板部位３０Ｅの重ね合わせ部位３０Ｅａ、３０Ｅｂは、溶接Ｗ５にて接合固定されている。同様に、下支持板部位３０Ｆの重ね合わせ部位３０Ｆａ、３０Ｆｂは、溶接Ｗ６にて接合固定されている。これにより、前側補強体４０と後側補強体５０は一体化されている。   The overlapping portions 30Ea and 30Eb of the upper support plate portion 30E in the overlapping configuration described above are joined and fixed by welding W5. Similarly, the overlapping portions 30Fa and 30Fb of the lower support plate portion 30F are joined and fixed by welding W6. Thereby, the front side reinforcing body 40 and the rear side reinforcing body 50 are integrated.

本実施形態における前側補強体４０と後側補強体５０の強度（剛性）の関係は、前側補強体４０の強度は後側補強体５０の強度に比較して弱くされている。これにより、補強部材３０の前部面板部位３０Ａの強度は、補強部材３０の他の部位である後部面板部位３０Ｂ、上傾斜面板部位３０Ｃ、下傾斜面板部位３０Ｄより弱くされている。なお、前部面板部位３０Ａすなわち前側補強体４０の強度は、衝突荷重が加わった際に生じる応力集中の程度を考慮して設定される。   The strength (rigidity) relationship between the front reinforcement 40 and the rear reinforcement 50 in the present embodiment is such that the strength of the front reinforcement 40 is weaker than the strength of the rear reinforcement 50. Thereby, the strength of the front surface plate portion 30A of the reinforcing member 30 is weaker than that of the rear surface plate portion 30B, the upper inclined surface plate portion 30C, and the lower inclined surface plate portion 30D which are other portions of the reinforcing member 30. The strength of the front face plate portion 30A, that is, the strength of the front side reinforcing member 40 is set in consideration of the degree of stress concentration that occurs when a collision load is applied.

上述した第１実施形態の構成は、本発明の第１の発明、第２の発明、第３の発明、及び第４の発明を充足する形態である。そのため、当該発明で説明した作用効果を得ることができる。   The configuration of the first embodiment described above is a form satisfying the first invention, the second invention, the third invention, and the fourth invention of the present invention. Therefore, the effects described in the present invention can be obtained.

先ず、第１の発明で説明したように、本第１実施形態は、補強部材３０は前側補強体４０と後側補強体５０とに分割構成されて、前側補強体４０の強度が後側補強体５０の強度より弱くされている。これにより、補強部材３０の衝突荷重Ｆの入力側となる前部面板部位３０Ａの強度（剛性）が、補強部材３０の他の部位３０Ｂ、３０Ｃ、３０Ｄの強度より相対的に弱くされる。その結果、応力集中及びそれに伴う座屈が生じるのを防止ないし抑制し、バンパリインフォースメント１４の折損を防止ないし抑制することができる。   First, as described in the first invention, in the first embodiment, the reinforcement member 30 is divided into the front reinforcement 40 and the rear reinforcement 50, and the strength of the front reinforcement 40 is the rear reinforcement. It is weaker than the strength of the body 50. Thereby, the strength (rigidity) of the front face plate portion 30A on the input side of the collision load F of the reinforcing member 30 is relatively weaker than the strengths of the other portions 30B, 30C, and 30D of the reinforcing member 30. As a result, it is possible to prevent or suppress the stress concentration and the resulting buckling, and to prevent or suppress the breakage of the bumper reinforcement 14.

図１０は、一体化された本体部材２０の面状板部材２４と補強部材３０の前部面板部位３０Ａとが、衝突荷重Ｆの入力により応力集中が生じて、座屈を生じた断面形状を示す。符号Ｘで囲んだ枠内の断面形状が、その状態を示す。本第１実施形態によれば、この様な状態となるのを防止ないし抑制することができる。すなわち、第１実施形態によれば、前部面板部位３０Ａの強度を弱くすることにより、衝突荷重が入力する部位である面状板部材２４及び前部面板部位３０Ａの強度を、応力集中が生じない適度な強度とすることができる。これにより、バンパリインフォースメント１４は衝突荷重Ｆにより応力集中による折損を防止ないし抑制することができて、衝突荷重Ｆはバンパリインフォースメントを通じてクラッシュボックスに伝達され、衝突エネルギーの吸収が効果的に行われる。   In FIG. 10, a stress concentration is caused by the input of the collision load F, and a cross-sectional shape in which the planar plate member 24 of the integrated main body member 20 and the front face plate portion 30A of the reinforcing member 30 are buckled Show. The cross-sectional shape in the frame enclosed by the symbol X indicates the state. According to the first embodiment, such a state can be prevented or suppressed. That is, according to the first embodiment, by weakening the strength of the front face plate portion 30A, stress concentration occurs in the strength of the planar plate member 24 and the front face plate portion 30A which are portions to which the collision load is input. There can be no moderate strength. Thereby, the bumper reinforcement 14 can prevent or suppress breakage due to stress concentration by the collision load F, the collision load F is transmitted to the crash box through the bumper reinforcement, and absorption of collision energy is effectively performed. .

次に、第２の発明及び第３の発明で説明したように、本第１実施形態によれば、分割構成される前側補強体４０と後側補強体５０は、上支持板部位３０Ｅ及び下支持板部位３０Ｆで、重ね合わせ構成をとる。その結果、当該部位３０Ｅ、３０Ｆの強度（剛性）は、補強部材３０の他の部位より強い強度となる。その結果、この強くされた補強部材３０における上支持板部位３０Ｅ、及び下支持板部位３０Ｆにより、主体部材２２における上側面板部位２２Ｂ及び下側面板部位２２Ｃの内方への変形移動を防止ないし抑制して、断面崩れを防止ないし抑制する。   Next, as described in the second and third inventions, according to the first embodiment, the front reinforcing body 40 and the rear reinforcing body 50 configured as divided are the upper support plate portion 30E and the lower side. In the support plate portion 30F, an overlapping configuration is adopted. As a result, the strength (rigidity) of the portions 30E and 30F becomes stronger than the other portions of the reinforcing member 30. As a result, the upper support plate portion 30E and the lower support plate portion 30F in the reinforced reinforcing member 30 prevent or suppress the inward deformation movement of the upper side plate portion 22B and the lower side plate portion 22C in the main body member 22. To prevent or suppress the collapse of the cross section.

図１０の符号Ｙで囲んだ箇所の図示状態は、断面崩れが生じた状態を示している。すなわち、補強部材３０における上支持板部位３０Ｅの箇所、及び下支持板部位３０Ｆの箇所の強度が不足すると、衝突荷重Ｆの入力により上側面板部位２２Ｂ及び下側面板部位２２Ｃが、内方に変形移動し、断面崩れを生じる。本第１実施形態によれば、この様な状態となるのを防止ないし抑制することができる。すなわち、上支持板部位３０Ｅの箇所、及び下支持板部位３０Ｆの箇所で補強部材３０を分割し、その分割構成を重ね合わせ構成とすることにより、上支持板部位３０Ｅ、及び下支持板部位３０Ｆの強度を強くすることができる。その結果、上側面板部位２２Ｂ及び下側面板部位２２Ｃの内方への変形移動を防止ないし抑制することができて、断面崩れを防止ないし抑制することができる。   The illustrated state of the portion surrounded by the reference symbol Y in FIG. 10 shows a state in which the cross section collapse occurs. That is, when the strength of the portion of the upper support plate portion 30E and the portion of the lower support plate portion 30F in the reinforcing member 30 is insufficient, the upper side plate portion 22B and the lower side plate portion 22C are deformed inwardly by the input of the collision load F. It moves and cross section collapse occurs. According to the first embodiment, such a state can be prevented or suppressed. That is, the reinforcing member 30 is divided at the portion of the upper support plate portion 30E and the portion of the lower support plate portion 30F, and the divided configuration is overlapped to form the upper support plate portion 30E and the lower support plate portion 30F. The strength of the As a result, it is possible to prevent or suppress the inward deformation movement of the upper side surface plate portion 22B and the lower side surface plate portion 22C, and to prevent or suppress the cross section collapse.

更に、第４の発明で説明したように、本第１実施形態によれば、分割構成とする前側補強体４０と後側補強体５０とを嵌め合せる構成を、上方及び下方共、前側補強体４０側を外側位置、後側補強体５０側を内側位置とする。これにより、前側補強体に作用する衝突荷重は前側補強体より内側に配設された後側補強体により確実に受け止めることができる。そして、衝突荷重Ｆの受け止めを上下位置でバランスよく適切に受け止めることができる。   Furthermore, as described in the fourth invention, according to the first embodiment, the upper and lower, front and rear reinforcements are configured to fit the front and rear reinforcements 40 and 50 in the divided configuration. The 40 side is an outer side position, and the rear reinforcing body 50 side is an inner side position. As a result, the collision load acting on the front reinforcement can be reliably received by the rear reinforcement disposed inside the front reinforcement. And the reception of the collision load F can be properly received at the upper and lower positions in a well-balanced manner.

〔第２実施形態〕
次に、第２実施形態を説明する。第２実施形態は図５に示される。第２実施形態は、分割構成とする上支持板部位３０Ｅと下支持板部位３０Ｆの重ね合わせ構成の形態が、第１実施形態と異なるのみで、他の構成は同じである。 Second Embodiment
Next, a second embodiment will be described. A second embodiment is shown in FIG. The second embodiment is the same as the first embodiment except that the form of the overlapping configuration of the upper support plate portion 30E and the lower support plate portion 30F which are divided is different from the first embodiment.
