Description
本発明は、車両前部構造に関する。 The present invention relates to a vehicle front structure.
従来の車両前部構造の中には、車両前方側のコラムユニット取付ブラケットの上面に板状の第１電子ユニット取付ブラケットを一体化して設け、この第１電子ユニット取付ブラケットの上面にその他の電子ユニットである第１電子ユニットに取付けているものがある（例えば、特許文献１参照）。そして、従来の車両前部構造におけるダッシュパネルは、第１電子ユニットに近接するよう、車体後方に膨出する膨出部を備えている。 In some conventional vehicle front structures, a plate-like first electronic unit mounting bracket is integrally provided on the upper surface of a column unit mounting bracket on the front side of the vehicle, and a first electronic unit, which is another electronic unit, is mounted on the upper surface of the first electronic unit mounting bracket (see, for example, Patent Document 1). The dash panel in the conventional vehicle front structure has a bulging portion that bulges rearward of the vehicle body so as to be close to the first electronic unit.
しかしながら、上述した従来の車両前部構造では、ダッシュパネルの膨出部と第１電子ユニットとの間に僅かの隙間を形成するのみとしているので、前突時に発生した車両前方から車両後方へ向かう荷重がダッシュパネルに加わった際に、ダッシュパネルが車両後方へ変位することによって、当該ダッシュパネルの膨出部が電子ユニットに当たって壊れる可能性を有しており、改善の余地があった。 However, in the above-described conventional vehicle front structure, only a small gap is formed between the bulging portion of the dash panel and the first electronic unit. Therefore, when a load directed from the front to the rear of the vehicle is applied to the dash panel in the event of a frontal collision, there is a possibility that the bulging portion of the dash panel hits the electronic unit and is broken due to displacement of the dash panel toward the rear of the vehicle.
本発明はこのような実状に鑑みてなされたものであって、その目的は、前突時に発生した車両後方へ向かう衝撃荷重が車両前方側の車体パネルに加わっても、車体パネルと連結している第１部材や第４部材と、第１部材や第４部材に連結している第２部材や第５部材が協働して衝撃荷重を吸収し、電子ユニットが取付けられた第２部材や第５部材の変形を抑えて、電子ユニットの故障を防止することが可能な車両前部構造を提供することにある。 SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and its object is to provide a vehicle front structure capable of preventing failure of an electronic unit by suppressing deformation of the second member and the fifth member to which the electronic unit is attached, by cooperating the first member and the fourth member connected to the vehicle body panel and the second member and the fifth member connected to the first member and the fifth member to absorb the impact load even if the impact load toward the rear of the vehicle is applied to the vehicle body panel on the front side of the vehicle in the event of a frontal collision. .
上記従来技術の有する課題を解決するために、本発明は、車両幅方向に沿って架設され、車体側部に取付けられるステアリングサポートメンバと、前記ステアリングサポートメンバに取付けられ、前記ステアリングサポートメンバから車両前方に延びて車両前方側の車体パネルに連結される第１部材と、前記第１部材と車両上面視で重なるように設けられ、前部と後部それぞれが前記第１部材に固定されている車両前部構造において、前記第２部材の下面に電子ユニットが取付けられている。 In order to solve the above-described problems of the prior art, the present invention provides a vehicle front structure including: a steering support member that is installed along the width direction of the vehicle and attached to a side portion of the vehicle body ; a first member that is attached to the steering support member and extends forward of the vehicle from the steering support member and is connected to a vehicle body panel on the front side of the vehicle;
上述の如く、本発明に係る車両前部構造は、車両幅方向に沿って架設され、車両幅方向の左右両端が車体側部に取付けられるステアリングサポートメンバと、該ステアリングサポートメンバに取付けられ、前記ステアリングサポートメンバから車両前方に延びて車両前方側の車体パネルに連結される第１部材と、該第１部材と車両上面視で重なるように設けられる第２部材とを有し、該第２部材の前部と後部は、それぞれ前記第１部材に固定されており、前記第２部材には、電子ユニットが取付けられている。
すなわち、本発明の車両前部構造においては、前突時に発生した車両前方から車両後方へ向かう衝撃荷重が車両前方側の車体パネルに加わっても、車体パネルと連結している第１部材と、第１部材に連結している第２部材が協働して衝撃荷重を吸収することになるので、電子ユニットが取付けられた第２部材の変形を最大限に抑えることが可能となり、電子ユニットの故障を効果的に防ぐことができる。
また、本発明の車両前部構造においては、第１部材及び第２部材という２つの部材が協働して車両前方側の車体パネルに対して突っ張る機能を発揮することになるので、車体パネルの車両後方への変位を低減させることができ、車体パネルとの衝突による電子ユニットの故障をより一層防止でき、電子ユニットの信頼性向上を図ることができる。
As described above, the vehicle front structure according to the present invention includes a steering support member that is installed along the vehicle width direction and has both left and right ends in the vehicle width direction attached to a vehicle body side portion, a first member that is attached to the steering support member, extends forward of the vehicle from the steering support member and is connected to a vehicle body panel on the front side of the vehicle, and a second member that is provided so as to overlap the first member when viewed from the top of the vehicle. An electronic unit is attached to the member.
That is, in the vehicle front structure of the present invention, even if an impact load directed from the front of the vehicle to the rear of the vehicle is applied to the vehicle body panel on the front side of the vehicle at the time of a frontal collision, the first member connected to the vehicle body panel and the second member connected to the first member cooperate to absorb the impact load. Therefore, deformation of the second member to which the electronic unit is attached can be suppressed to the maximum extent, and failure of the electronic unit can be effectively prevented.
In addition, in the vehicle front structure of the present invention, the two members, the first member and the second member, work together to exert a function of stretching the vehicle body panel on the front side of the vehicle. Therefore, it is possible to reduce the displacement of the vehicle body panel toward the rear of the vehicle, further prevent failure of the electronic unit due to collision with the vehicle body panel, and improve the reliability of the electronic unit.
以下、本発明を図示の実施の形態に基づいて詳細に説明する。なお、図において、矢印Ｆｒ方向は車両前方を示し、矢印Ｕ方向は車両上方を示している。 BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail based on the illustrated embodiments. In the drawings, the direction of arrow Fr indicates the front of the vehicle, and the direction of arrow U indicates the upper direction of the vehicle.
［第１実施形態］
図１～図５は本発明の第１実施形態に係る車両前部構造を示すものである。図１～図５に示すように、本実施形態の車両前部構造において、車室Ｒ内の前方側上部には、車両幅方向に沿って架設され、車両幅方向の左右両端が車体側部（図示せず）に取付けられるステアリングサポートメンバ１と、ステアリングサポートメンバ１に取付けられ、該ステアリングサポートメンバ１から車両前方に延びて車両前方側の車体パネルのカウルトップパネル２（もしくはダッシュパネル３）にリンフォースメント４を介して連結される第１部材５と、第１部材５と車両上面視で重なるように設けられる第２部材６とを有しており、第２部材６の前部６ａと後部６ｂは、それぞれ第１部材５に固定されている。そして、第２部材６には、カプラ、コントローラ、各種センサ、アンテナ等の電子ユニット７が取付けられている。
なお、本実施形態のステアリングサポートメンバ１は、パイプ状の部材で構成され、各種の艤装品を設置する大型樹脂成形部品のインストルメントパネル８の内部に配置されており、該インストルメントパネル８を支持するとともに、運転席側では、図示しないステアリングコラムやステアリングホイールなどを支持している。また、リンフォースメント４は、第１部材５とカウルトップパネル２との連結箇所を補強するために、カウルトップパネル２の車室Ｒ内側の表面に取付けられている。さらに、インストルメントパネル８の内部には、空調用のダクト８１が配置されている。
[First embodiment]
1 to 5 show a vehicle front structure according to a first embodiment of the invention. As shown in FIGS. 1 to 5, in the vehicle front structure of the present embodiment, a steering support member 1 is installed along the vehicle width direction in the upper front portion of the vehicle interior R, and both left and right ends in the vehicle width direction are attached to vehicle body side portions (not shown). A second member 6 is provided so as to overlap when viewed from the top of the vehicle, and a front portion 6a and a rear portion 6b of the second member 6 are fixed to the first member 5, respectively. An electronic unit 7 such as a coupler, a controller, various sensors, and an antenna is attached to the second member 6 .
The steering support member 1 of the present embodiment is made of a pipe-shaped member, and is arranged inside an instrument panel 8, which is a large-sized resin molded part on which various fittings are installed. In addition to supporting the instrument panel 8, it supports a steering column, a steering wheel, and the like (not shown) on the driver's seat side. Further, the reinforcement 4 is attached to the surface of the cowl top panel 2 on the inner side of the passenger compartment R in order to reinforce the connecting portion between the first member 5 and the cowl top panel 2 . Furthermore, an air conditioning duct 81 is arranged inside the instrument panel 8 .
本実施形態の車両前部構造における第１部材５は、図１～図３及び図５に示すように、第２部材６の車両上側に配置されており、ステアリングサポートメンバ１とカウルトップパネル２との間で、ステアリングサポートメンバ１から車両前後方向に延びている。そして、第１部材５の前部５ａはリンフォースメント４を介してカウルトップパネル２に接合され、第１部材５の後部５ｂはステアリングサポートメンバ１に接合されている。また、第１部材５は、平板状の本体部５１の左右両側に下方へ向かってほぼ直角に折り曲げたフランジ部５１ａを有している。しかも、第１部材５は、電子ユニット７の後端７ａよりも車両後方側に位置する部分に形成された湾曲部５２を有しており、該湾曲部５２は、車両上方へ向かって突出する湾曲形状に形成されている。
このような位置に湾曲部５２を設けることによって、前突時に衝撃荷重が第１部材５に入力された場合に、湾曲部５２が変形の起点となって第１部材５が変形することになり、第１部材５の衝撃荷重吸収が促進されるとともに、湾曲部５２の変形による電子ユニット７への影響が最小限となるように構成されている。
As shown in FIGS. 1 to 3 and 5, the first member 5 in the vehicle front structure of the present embodiment is arranged on the vehicle upper side of the second member 6, and extends between the steering support member 1 and the cowl top panel 2 in the vehicle front-rear direction from the steering support member 1. A front portion 5 a of the first member 5 is joined to the cowl top panel 2 via a reinforcement 4 , and a rear portion 5 b of the first member 5 is joined to the steering support member 1 . In addition, the first member 5 has flange portions 51a that are bent downward at substantially right angles on both left and right sides of the main body portion 51 in the form of a flat plate. Moreover, the first member 5 has a curved portion 52 formed in a portion located on the vehicle rear side relative to the rear end 7a of the electronic unit 7, and the curved portion 52 is formed in a curved shape protruding upward from the vehicle.
By providing the curved portion 52 at such a position, when an impact load is input to the first member 5 at the time of a frontal collision, the curved portion 52 becomes a starting point of deformation and the first member 5 is deformed.
一方、本実施形態の車両前部構造における第２部材６は、図１～図３及び図５に示すように、第１部材５の車両下側に配置されており、第１部材５の前部５ａに固定される第１固定部６１と、第１固定部６１から車両後方へ向かって車両下側に傾斜しながら延びる本体部６２と、本体部６２の後端部６２ａから第１部材５へ向かって立ち上がるように屈曲する屈曲部６３と、屈曲部６３の第１部材５側の端部６３ａに設けられ、かつ第１部材５の後部５ｂに固定される第２固定部６４を有している。すなわち、第２部材６は、第１部材５よりも車両後方側の長さが短く、第１部材５の車両前後方向の範囲内に収まるように形成されている。また、第２部材６は、平板状の本体部６２の左右両側に上方へ向かってほぼ直角に折り曲げたフランジ部６２ｂを有しており、第１固定部６１は、本体部６２のフランジ部６２ｂより第１部材５の前部５ａへ向かって車両上方に延びている。電子ユニット７は、ボルト７０及びナット７１などの締結具を用いて、第２部材６の本体部６２の下面に固定されている。
しかも、第２部材６の屈曲部６３は、車両側面視で第１部材５の湾曲部５２とステアリングサポートメンバ１との車両前後方向の間に設けられている。これによって、第２部材６の屈曲部６３は、第１部材５の湾曲部５２よりも車両後方に位置することになり、前突時に衝撃荷重が第１部材５及び第２部材６に入力された場合に、第２部材６の屈曲部６３は、第１部材５の湾曲部５２が変形した後に変形し、第１部材５の湾曲部５２も衝撃荷重を吸収できるように構成している。
On the other hand, as shown in FIGS. 1 to 3 and 5 , the second member 6 in the vehicle front structure of the present embodiment is arranged on the vehicle lower side of the first member 5, and includes a first fixing portion 61 fixed to the front portion 5a of the first member 5, a main body portion 62 extending from the first fixing portion 61 toward the rear of the vehicle while being inclined toward the vehicle lower side, a bending portion 63 bending so as to rise from the rear end portion 62a of the main body portion 62 toward the first member 5, and a bending portion. A second fixing portion 64 is provided at the end portion 63 a of the portion 63 on the side of the first member 5 and fixed to the rear portion 5 b of the first member 5 . That is, the second member 6 is shorter on the vehicle rear side than the first member 5 and is formed to fit within the range of the first member 5 in the vehicle front-rear direction. In addition, the second member 6 has flange portions 62b that are bent substantially at right angles upward on both left and right sides of a flat plate-like body portion 62, and the first fixing portion 61 extends upward from the vehicle toward the front portion 5a of the first member 5 from the flange portions 62b of the body portion 62. The electronic unit 7 is fixed to the lower surface of the main body portion 62 of the second member 6 using fasteners such as bolts 70 and nuts 71 .
Moreover, the bent portion 63 of the second member 6 is provided between the curved portion 52 of the first member 5 and the steering support member 1 in the vehicle front-rear direction as viewed from the side of the vehicle. As a result, the bent portion 63 of the second member 6 is positioned further to the rear of the vehicle than the curved portion 52 of the first member 5. When an impact load is input to the first member 5 and the second member 6 at the time of a frontal collision, the bent portion 63 of the second member 6 deforms after the curved portion 52 of the first member 5 deforms, and the curved portion 52 of the first member 5 can also absorb the impact load.
また、本実施形態の車両前部構造は、図１～図３及び図５に示すように、ステアリングサポートメンバ１に取付けられ、ステアリングサポートメンバ１から第２部材６へ向かって延びる第３部材９を有している。この第３部材９の前部９ａは、第２部材６側を向く第３部材面部９１を有し、第２部材６の後部６ｂは、第３部材面部９１と対向して配置される第２部材面部６５を有しており、第２部材面部６５及び第３部材面部９１は、重ね合わせ可能な平坦面状に形成されている。しかも、第２部材６と第３部材９とは、第２部材面部６５と第３部材面部９１が重ね合わされた状態で接合されることによって連結されている。そのため、第２部材面部６５と第３部材面部９１とが面で接触することになり、前突時における第２部材６からの衝撃荷重を第３部材９が効率良く伝達して、第２部材６の変形が最大限に抑えられるようになっている。それに加えて、前突時において、カウルトップパネル２に車両後方へ向かう荷重が発生しても、第１部材５はステアリングサポートメンバ１へ当該荷重が直接伝達され、第２部材６は第３部材９を介してステアリングサポートメンバ１へ当該荷重が伝達されることになり、電子ユニット７が取付けられる第２部材６の変形がより一層抑えられるようになっている。
なお、第３部材９の前部９ａは、横向きのＶ字型の平面形状に形成されており、上側が第３部材面部９１として構成されている。第３部材９の左右両側には、下方へ向かってほぼ直角に折り曲げたフランジ部９２を有しており、第３部材９の後部９ｂは、フランジ部９２の後端部分をステアリングサポートメンバ１の外周面に接合することによって、ステアリングサポートメンバ１に取付けられている。
1 to 3 and 5, the vehicle front structure of this embodiment has a third member 9 attached to the steering support member 1 and extending from the steering support member 1 toward the second member 6. The front portion 9a of the third member 9 has a third member surface portion 91 facing the second member 6 side, and the rear portion 6b of the second member 6 has a second member surface portion 65 arranged to face the third member surface portion 91, and the second member surface portion 65 and the third member surface portion 91 are formed in a flat surface shape that can be superimposed. Moreover, the second member 6 and the third member 9 are connected by being joined while the second member surface portion 65 and the third member surface portion 91 are overlapped. Therefore, the second member surface portion 65 and the third member surface portion 91 come into surface contact, and the third member 9 efficiently transmits the impact load from the second member 6 at the time of frontal collision, thereby suppressing the deformation of the second member 6 to the maximum. In addition, even if a load is applied to the cowl top panel 2 toward the rear of the vehicle in the event of a frontal collision, the first member 5 directly transmits the load to the steering support member 1, and the second member 6 transmits the load to the steering support member 1 via the third member 9, thereby further suppressing deformation of the second member 6 to which the electronic unit 7 is attached.
The front portion 9 a of the third member 9 is formed in a horizontal V-shaped planar shape, and the upper side is configured as a third member surface portion 91 . Left and right sides of the third member 9 have flange portions 92 that are bent downward at substantially right angles, and the rear portion 9b of the third member 9 is attached to the steering support member 1 by joining the rear end portion of the flange portion 92 to the outer peripheral surface of the steering support member 1.
さらに、本実施形態の車両前部構造は、図１～図３に示すように、第１部材５から第２部材６へ向かって延び、第２部材６に連結される橋渡し部５３を有している。この橋渡し部５３は、本体部５１の左右両側の前後２箇所からフランジ部５１ａよりも車両下方へ延び、第２部材６側で１箇所に合流し、第２部材６側が車両前後方向に所定の長さを有する形状に形成されている。一方、第２部材６は、本体部６２の左右両側からフランジ部６２ｂよりも車両上方へ延び、車両前後方向に所定の長さを有する形状に形成されており、橋渡し部５３と第２部材６とが連結する連結部Ｂの接合面積を確保している。そして、橋渡し部５３と第２部材６とが連結する連結部Ｂと車両上面視で重なる位置には、電子ユニット７が設けられている。
この橋渡し部５３が存在することにより、荷重が入力された場合に、第１部材５と第２部材６とが互いに近づくような変形に対して剛性が向上することになり、電子ユニット７が取付けられる第２部材６の変形が抑えられるようになっている。
1 to 3, the vehicle front structure of this embodiment has a bridge portion 53 extending from the first member 5 toward the second member 6 and connected to the second member 6. As shown in FIGS. The bridging portion 53 extends downward from the flange portion 51a from two front and rear locations on both the left and right sides of the body portion 51, merges at one location on the second member 6 side, and has a predetermined length in the vehicle front-rear direction on the second member 6 side. On the other hand, the second member 6 extends from both left and right sides of the main body portion 62 toward the upper side of the vehicle than the flange portion 62b, and is formed in a shape having a predetermined length in the vehicle front-rear direction. The electronic unit 7 is provided at a position overlapping the connecting portion B where the bridging portion 53 and the second member 6 are connected when viewed from the top of the vehicle.
Due to the presence of this bridging portion 53, when a load is input, the rigidity against deformation such that the first member 5 and the second member 6 approach each other is improved, and the deformation of the second member 6 to which the electronic unit 7 is attached is suppressed.
このように、本発明の第１実施形態に係る車両前部構造は、車両幅方向に沿って架設され、車両幅方向の左右両端が車体側部に取付けられるステアリングサポートメンバ１と、ステアリングサポートメンバ１に取付けられ、ステアリングサポートメンバ１から車両前方に延びて車両前方側のカウルトップパネル２などの車体パネルに連結される第１部材５と、第１部材５と車両上面視で重なるように設けられる第２部材６とを有し、第２部材６の前部６ａと後部６ｂは、それぞれ第１部材５に固定されている。そして、本実施形態の第２部材６には、電子ユニット７が取付けられている。
したがって、本実施形態の車両前部構造においては、前突時に発生した車両後方へ向かう衝撃荷重が車両前方側のカウルトップパネル２に加わっても、カウルトップパネル２と連結している第１部材５と、第１部材５に連結している第２部材６が協働して衝撃荷重を吸収することになるので、電子ユニット７が取付けられた第２部材６の変形を最大限に抑えることができ、電子ユニット７の故障を防ぐ効果を得ることができる。しかも、本実施形態の車両前部構造においては、車両上面視で重なるように設けられた第１部材５及び第２部材６の２部材が協働して車両前方側のカウルトップパネル２を突っ張るようにして支えることになるので、カウルトップパネル２の車両後方への変位を抑えることができ、カウルトップパネル２との衝突による電子ユニット７の故障を効果的に防止でき、電子ユニット７の信頼性を向上させることができる。
As described above, the vehicle front structure according to the first embodiment of the present invention includes: a steering support member 1 that is installed along the vehicle width direction and has both left and right ends in the vehicle width direction attached to the vehicle body side portions; 6b are fixed to the first member 5 respectively. An electronic unit 7 is attached to the second member 6 of the present embodiment.
Therefore, in the vehicle front structure of the present embodiment, even if an impact load toward the rear of the vehicle is applied to the cowl top panel 2 on the front side of the vehicle in the event of a frontal collision, the first member 5 connected to the cowl top panel 2 and the second member 6 connected to the first member 5 work together to absorb the impact load. Moreover, in the vehicle front structure of the present embodiment, the first member 5 and the second member 6, which are provided so as to overlap each other when viewed from the top of the vehicle, work together to support the cowl top panel 2 on the front side of the vehicle so that displacement of the cowl top panel 2 toward the rear of the vehicle can be suppressed.
また、本実施形態の車両前部構造において、第１部材５は、電子ユニット７の後端７ａよりも車両後方側に位置する部分に形成された湾曲部５２を有しているので、前突時に衝撃荷重が第１部材５に入力された場合に、湾曲部５２が変形の起点となって第１部材５が変形することになり、第１部材５による衝撃荷重の吸収性能を促進させることができる。しかも、本実施形態の車両前部構造では、湾曲部５２が電子ユニット７よりも車両後方に配置されているので、湾曲部５２の変形による電子ユニット７への影響を最小限とすることができ、電子ユニット７の故障防止効果をより一層高めることができる。 In addition, in the vehicle front structure of the present embodiment, the first member 5 has the curved portion 52 formed in a portion located on the vehicle rear side relative to the rear end 7a of the electronic unit 7. Therefore, when an impact load is input to the first member 5 at the time of a frontal collision, the curved portion 52 becomes a starting point of deformation and the first member 5 is deformed. Moreover, in the vehicle front structure of the present embodiment, the curved portion 52 is arranged behind the electronic unit 7 in the vehicle, so that the deformation of the curved portion 52 can minimize the influence of the deformation of the electronic unit 7 on the electronic unit 7, and the failure prevention effect of the electronic unit 7 can be further enhanced.
さらに、本実施形態の車両前部構造において、第２部材６は、第１部材５の前部５ａに固定される第１固定部６１と、第１固定部６１から車両後方へ延びる本体部６２と、本体部６２の後端部６２ａから第１部材５へ向かって屈曲する屈曲部６３と、屈曲部６３の第１部材５側の端部６３ａに設けられ、かつ第１部材５の後部５ｂに固定される第２固定部６４を有している。また、第２部材６の屈曲部６３は、車両側面視で第１部材５の湾曲部５２とステアリングサポートメンバ１との間に設けられている。
したがって、本実施形態の車両前部構造によれば、前突時に衝撃荷重が第１部材５及び第２部材６に入力されると、第２部材６の屈曲部６３は第１部材５の湾曲部５２が変形した後に変形することになるので、第１部材５の湾曲部５２も衝撃荷重を吸収することが可能となり、電子ユニット７の故障を更に防ぐことができる。
Further, in the vehicle front structure of the present embodiment, the second member 6 has a first fixing portion 61 fixed to the front portion 5a of the first member 5, a main body portion 62 extending rearward of the vehicle from the first fixing portion 61, a bent portion 63 bent from a rear end portion 62a of the main body portion 62 toward the first member 5, and a second fixed portion 64 provided at an end portion 63a of the bent portion 63 on the first member 5 side and fixed to the rear portion 5b of the first member 5. are Further, the bent portion 63 of the second member 6 is provided between the curved portion 52 of the first member 5 and the steering support member 1 when viewed from the side of the vehicle.
Therefore, according to the vehicle front structure of the present embodiment, when an impact load is input to the first member 5 and the second member 6 at the time of a frontal collision, the bent portion 63 of the second member 6 is deformed after the curved portion 52 of the first member 5 is deformed.
また、本実施形態の車両前部構造は、ステアリングサポートメンバ１に取付けられ、ステアリングサポートメンバ１から第２部材６へ向かって延びる第３部材９を有している。第３部材９は、第２部材６側を向く第３部材面部９１を有している一方、第２部材６は、第３部材面部９１と対向して配置される第２部材面部６５を有している。そして、第２部材６と第３部材９とは、第２部材面部６５と第３部材面部９１が重ね合わされた状態で接合されることによって連結されている。
したがって、本実施形態の車両前部構造によれば、第２部材６と第３部材９との連結部分である第２部材面部６５と第３部材面部９１とが、面で接触することになるので、前突時に入力される第２部材６からの衝撃荷重を第３部材９がステアリングサポートメンバ１に効率的に伝達することができ、電子ユニット７が取付けられる第２部材６の変形を最大限に抑えることができる。しかも、本実施形態の車両前部構造によれば、前突時に、カウルトップパネル２に車両後方へ向かう衝撃荷重が発生しても、第１部材５はステアリングサポートメンバ１へ当該衝撃荷重を伝達し、第２部材６は第３部材９を介してステアリングサポートメンバ１へ当該衝撃荷重を伝達することが可能になるので、電子ユニット７が取付けられる第２部材６の変形を効果的に抑えることができ、電子ユニット７の故障防止効果を更に高めることができる。
The vehicle front structure of this embodiment also has a third member 9 attached to the steering support member 1 and extending from the steering support member 1 toward the second member 6 . The third member 9 has a third member surface portion 91 facing the second member 6 side, while the second member 6 has a second member surface portion 65 arranged to face the third member surface portion 91 . The second member 6 and the third member 9 are connected by being joined together in a state in which the second member surface portion 65 and the third member surface portion 91 are overlapped.
Therefore, according to the vehicle front portion structure of the present embodiment, the second member surface portion 65 and the third member surface portion 91, which are the connecting portions of the second member 6 and the third member 9, are in surface contact, so that the impact load input from the second member 6 in the event of a frontal collision can be efficiently transmitted to the steering support member 1 by the third member 9, and deformation of the second member 6 to which the electronic unit 7 is attached can be suppressed to the maximum. Moreover, according to the vehicle front structure of the present embodiment, even if an impact load directed toward the rear of the vehicle is generated on the cowl top panel 2 at the time of a frontal collision, the first member 5 transmits the impact load to the steering support member 1, and the second member 6 can transmit the impact load to the steering support member 1 via the third member 9. Therefore, deformation of the second member 6 to which the electronic unit 7 is attached can be effectively suppressed, and the failure prevention effect of the electronic unit 7 can be further enhanced.
そして、本実施形態の車両前部構造は、第１部材５から第２部材６へ向かって延び、第２部材６に連結される橋渡し部５３を有しており、橋渡し部５３と第２部材６とが連結する連結部Ｂと車両上面視で重なる位置には、電子ユニット７が設けられているので、荷重が入力された場合に、第１部材５と第２部材６とが互いに近づくような変形に対する剛性を向上させ、電子ユニット７が取付けられる第２部材６の変形を抑えることができ、電子ユニット７の故障を防ぐ効果を得ることができる。 The vehicle front structure of the present embodiment includes a bridging portion 53 extending from the first member 5 toward the second member 6 and connected to the second member 6. Since the electronic unit 7 is provided at a position where the bridging portion 53 and the second member 6 are overlapped with the connecting portion B when viewed from the top of the vehicle, when a load is input, the rigidity against deformation such that the first member 5 and the second member 6 approach each other is improved, and the deformation of the second member 6 to which the electronic unit 7 is attached is prevented. Therefore, it is possible to obtain the effect of preventing the failure of the electronic unit 7 .

[Second embodiment]
6 and 7 show a vehicle front structure according to a second embodiment of the invention. Note that the same reference numerals are given to the same parts as those described in the above-described first embodiment, and redundant descriptions are omitted. Also, members corresponding to those described in the first embodiment are denoted by reference numerals A, and different points will be described.
As shown in FIGS. 6 and 7, in the vehicle front structure of the second embodiment, instead of the first member 5, the second member 6 and the third member 9 of the first embodiment, a fourth member 5A, a fifth member 6A and a sixth member 9A are used as corresponding members. A rear portion 6b of the fifth member 6A in the second embodiment is fixed to a front portion 9a of a sixth member 9A extending forward of the vehicle from the steering support member 1, and the sixth member 9A is connected to the fifth member 6A. Therefore, the front portion 9a of the sixth member 9A has a sixth member surface portion 91A facing the fifth member 6A side, and the rear portion 6b of the fifth member 6A has a fifth member surface portion 65A arranged to face the sixth member surface portion 91A.
本実施形態における第５部材６Ａは、図６及び図７に示すように、第４部材５Ａの前部５ａに固定される第４固定部６１Ａと、第４固定部６１Ａから車両後方へ延びる本体部６２と、本体部６２の後端部６２ａに位置し第６部材９Ａの前部９ａに固定される第５固定部６４Ａを有している。また、第５部材６Ａの第４固定部６１Ａと本体部６２とは、車両後方に延び、かつ車両後方へ向かうほど車両下方へ湾曲する曲がり部６６を介して接続されており、第５部材６Ａは、第１実施形態の第２部材６よりも急な角度で、車両後方へ向かって車両下側に傾斜しながら延びている。
曲がり部６６は、車両上方へ向かって突出する湾曲形状に形成され、前突時に発生する車両後方への荷重に対して高い強度の構造であり、カウルトップパネル２の車両後方への変位を抑える効果を有している。しかも、このような形状の曲がり部６６が介在することにより、第５部材６Ａに取付けられた電子ユニット７とカウルトップパネル２（リンフォースメント４を含む）との車両前後方向の間隔Ｓであるクリアランスが確保されるようになっている。
As shown in FIGS. 6 and 7, the fifth member 6A in the present embodiment includes a fourth fixing portion 61A fixed to the front portion 5a of the fourth member 5A, a main body portion 62 extending rearward of the vehicle from the fourth fixing portion 61A, and a fifth fixing portion 64A located at the rear end portion 62a of the main body portion 62 and fixed to the front portion 9a of the sixth member 9A. In addition, the fourth fixing portion 61A and the main body portion 62 of the fifth member 6A are connected via a bending portion 66 that extends rearward of the vehicle and curves downward toward the rear of the vehicle.
The bent portion 66 is formed in a curved shape protruding upward of the vehicle, has a structure with high strength against the load to the rear of the vehicle generated in the event of a frontal collision, and has the effect of suppressing the displacement of the cowl top panel 2 to the rear of the vehicle. Moreover, the presence of the curved portion 66 having such a shape ensures a clearance, which is the space S in the vehicle front-rear direction, between the electronic unit 7 attached to the fifth member 6A and the cowl top panel 2 (including the reinforcement 4).
また、本実施形態のカウルトップパネル２には、図６及び図７に示すように、車両後方へ向かって突出する突出部２１を有しており、該突出部２１によって、前突時の衝撃荷重に対するカウルトップパネル２の剛性を向上させるように構成している。しかも、電子ユニット７は、突出部２１の下端２１ａよりも車両下方に設けられている。これにより、本実施形態の車両前部構造では、電子ユニット７とカウルトップパネル２の突出部２１とが車両正面視で重ならないように位置している。 Further, as shown in FIGS. 6 and 7, the cowl top panel 2 of the present embodiment has a projecting portion 21 that projects toward the rear of the vehicle, and the projecting portion 21 is configured to improve the rigidity of the cowl top panel 2 against the impact load in the event of a frontal collision. Moreover, the electronic unit 7 is provided below the lower end 21 a of the projecting portion 21 in the vehicle. Thus, in the vehicle front structure of the present embodiment, the electronic unit 7 and the protruding portion 21 of the cowl top panel 2 are positioned so as not to overlap when viewed from the front of the vehicle.
このように、本発明の第２実施形態の車両前部構造において、車両幅方向に沿って架設され、車両幅方向の左右両端が車体側部に取付けられるステアリングサポートメンバ１と、ステアリングサポートメンバ１に取付けられ、ステアリングサポートメンバ１から車両前方に延びて車両前方側のカウルトップパネル２などの車体パネルに連結される第４部材５Ａと、第４部材５Ａと車両上面視で重なるように設けられる第５部材６Ａとを有し、第５部材６Ａの前部６ａは、第４部材５Ａに固定されている。そして、第５部材６Ａには、電子ユニット７が取付けられている。
また、本実施形態の車両前部構造において、ステアリングサポートメンバ１に取付けられ、ステアリングサポートメンバ１から車両前方へ向かって延びる第６部材９Ａを有しており、第６部材９Ａは、第５部材６Ａに連結されている。
したがって、本実施形態の車両前部構造においても、上記第１実施形態の車両前部構造と同様の効果をそれぞれ得ることができる。

An electronic unit 7 is attached to the fifth member 6A.
Further, in the vehicle front structure of the present embodiment, the sixth member 9A is attached to the steering support member 1 and extends from the steering support member 1 toward the front of the vehicle. The sixth member 9A is connected to the fifth member 6A.
Therefore, in the vehicle front structure of the present embodiment as well, effects similar to those of the vehicle front structure of the first embodiment can be obtained.
さらに、本実施形態の車両前部構造において、第５部材６Ａは、第４部材５Ａの前部５ａに固定される第４固定部６１Ａと、第４固定部６１Ａから車両後方へ延びる本体部６２と、本体部６２の後端部６２ａに位置し第６部材９Ａの前部９ａに固定される第５固定部６４Ａを有している。そして、第５部材６Ａの第４固定部６１Ａと本体部６２とは、車両後方に延び、かつ車両後方へ向かうほど車両下方へ湾曲する曲がり部６６を介して接続されている。
したがって、本実施形態の車両前部構造は、第５部材６Ａが、前突時に発生する車両後方への荷重に対して高い強度の曲がり部６６を有しているので、前突時に生じるカウルトップパネル２の車両後方への変位を抑えることができる。しかも、本実施形態の曲がり部６６は、車両後方へ向かうほど車両下方へ湾曲し、電子ユニット７とカウルトップパネル２との車両前後方向のクリアランスを確保することが可能となるので、電子ユニット７の取付け作業性を向上させることができるとともに、カウルトップパネル２の車両前後方向への変位の許容レベルを高めることができる。
Furthermore, in the vehicle front structure of the present embodiment, the fifth member 6A has a fourth fixing portion 61A fixed to the front portion 5a of the fourth member 5A, a main body portion 62 extending rearward of the vehicle from the fourth fixing portion 61A, and a fifth fixing portion 64A located at the rear end portion 62a of the main body portion 62 and fixed to the front portion 9a of the sixth member 9A. The fourth fixing portion 61A of the fifth member 6A and the main body portion 62 are connected via a bent portion 66 that extends rearward of the vehicle and curves downward toward the rear of the vehicle.
Therefore, in the vehicle front structure of the present embodiment, the fifth member 6A has the bent portion 66 that has a high strength against the load to the rear of the vehicle that occurs in the event of a frontal collision. Moreover, the bent portion 66 of the present embodiment curves downward toward the rear of the vehicle, making it possible to secure a clearance between the electronic unit 7 and the cowl top panel 2 in the vehicle front-rear direction. Therefore, the workability of mounting the electronic unit 7 can be improved, and the allowable level of displacement of the cowl top panel 2 in the vehicle front-rear direction can be increased.
また、本実施形態の車両前部構造において、車体パネルのカウルトップパネル２は、車両後方へ向かって突出する突出部２１を有しているので、前突時の衝撃荷重に対するカウルトップパネル２の剛性を向上させることができる。したがって、本実施形態の車両前部構造によれば、前突時におけるカウルトップパネル２の車両後方への変位を抑えることができ、カウルトップパネル２等との衝突による電子ユニット７の故障を防ぐことができる。
しかも、本実施形態の車両前部構造において、電子ユニット７は、突出部２１の下端２１ａよりも車両下方に設けられ、電子ユニット７とカウルトップパネル２の突出部２１とが車両正面視で重ならない位置に配置されているので、電子ユニット７とカウルトップパネル２やダッシュパネル３とのクリアランスを十分に確保でき、カウルトップパネル２等との衝突による電子ユニット７の故障をより効果的に防ぐことができる。
In addition, in the vehicle front structure of the present embodiment, the cowl top panel 2 of the vehicle body panel has the protruding portion 21 that protrudes toward the rear of the vehicle, so that the rigidity of the cowl top panel 2 against the impact load at the time of a frontal collision can be improved. Therefore, according to the vehicle front structure of the present embodiment, displacement of the cowl top panel 2 toward the rear of the vehicle in the event of a frontal collision can be suppressed, and failure of the electronic unit 7 due to collision with the cowl top panel 2 or the like can be prevented.
Moreover, in the vehicle front structure of the present embodiment, the electronic unit 7 is provided below the lower end 21a of the projecting portion 21 in the vehicle, and is arranged at a position where the electronic unit 7 and the projecting portion 21 of the cowl top panel 2 do not overlap when viewed from the front of the vehicle. Therefore, a sufficient clearance can be secured between the electronic unit 7 and the cowl top panel 2 or the dash panel 3, and failure of the electronic unit 7 due to collision with the cowl top panel 2 or the like can be more effectively prevented.
そして、本実施形態の車両前部構造において、第４部材５Ａから第５部材６Ａへ向かって延び、第５部材６Ａに連結される橋渡し部５３を有しており、橋渡し部５３と第５部材６Ａとが連結する連結部Ｂと車両上面視で重なる位置には、電子ユニット７が設けられているので、上記第１実施形態の車両前部構造と同様の効果を得ることができる。 In the vehicle front structure of the present embodiment, the bridging portion 53 extends from the fourth member 5A toward the fifth member 6A and is connected to the fifth member 6A. Since the electronic unit 7 is provided at a position where the bridging portion 53 and the fifth member 6A overlap with the connecting portion B when viewed from the top of the vehicle, the same effects as those of the vehicle front structure of the first embodiment can be obtained.
