Description

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

ストラットハウスとフロントピラーとの間にアッパーフレームのような閉断面構造の補強部材を設け、車体の強度を向上させる技術が知られている。   A technique for improving the strength of a vehicle body by providing a reinforcing member having a closed cross-sectional structure such as an upper frame between a strut house and a front pillar is known.

上述した従来の車体構造は、例えば、特許文献１に開示されている。   The conventional vehicle body structure described above is disclosed in, for example, Patent Document 1.

特公平６−６２０９７号公報Japanese Patent Publication No. 6-62097

しかしながら、ストラットハウスに閉断面構造のアッパーフレームを接合すると、ストラットハウス部分の剛性が極めて高くなり、車両の衝撃吸収特性の面では不利になる。また、従来の車体構造においては、構造が複雑になる問題があり、閉断面構造のアッパーフレームを用いると、アッパーフレームをなす内側パネルの内面にストラットハウスを接合し、外側パネルの後端をフロントピラーに接合することになるので、ストラットハウスとフロントピラーとがそれぞれ別の板面に接合されることになり、車体構造の組立精度が低下するおそれがあった。   However, if an upper frame having a closed cross-sectional structure is joined to the strut house, the strut house portion has extremely high rigidity, which is disadvantageous in terms of shock absorption characteristics of the vehicle. In addition, the conventional vehicle body structure has a problem that the structure becomes complicated. When an upper frame having a closed cross-section structure is used, the strut house is joined to the inner surface of the inner panel forming the upper frame, and the rear end of the outer panel is connected to the front. Since it is joined to the pillar, the strut house and the front pillar are joined to different plate surfaces, respectively, and there is a possibility that the assembly accuracy of the vehicle body structure is lowered.

従って、本願発明は上記課題を解決するものであって、簡素な構成で良好な衝撃エネルギー吸収特性を保ちながら車体強度を補強すると共に車体組立精度を向上させることができる車体構造を提供することを目的とする。   Accordingly, the present invention solves the above-described problems, and provides a vehicle body structure that can reinforce the vehicle body strength and improve the vehicle body assembly accuracy while maintaining good impact energy absorption characteristics with a simple configuration.

図１乃至４に示すように、車体１には車体前後方向に延設するサイドメンバ２が設けられる一方、車体１の前方にはエンジンルーム３が形成されている。サイドメンバ２の車幅方向外側には、車輪に接続されるサスペンション等（図示省略）を収納するためのストラットハウス４が設けられており、ストラットハウス４の後部には、車幅方向に延設するダッシュパネル５が設けられている。ストラットハウス４とダッシュパネル５とは、ストラットハウス４の後壁上部に形成される接合部４ａとダッシュパネル５の前壁上部に形成される接合部５ａとにより接合されている。   As shown in FIGS. 1 to 4, the vehicle body 1 is provided with a side member 2 extending in the longitudinal direction of the vehicle body, and an engine room 3 is formed in front of the vehicle body 1. A strut house 4 is provided outside the side member 2 in the vehicle width direction so as to store a suspension or the like (not shown) connected to the wheels. A rear portion of the strut house 4 extends in the vehicle width direction. A dash panel 5 is provided. The strut house 4 and the dash panel 5 are joined by a joint 4 a formed on the upper rear wall of the strut house 4 and a joint 5 a formed on the upper front wall of the dash panel 5.

ダッシュパネル５の両側部には、車体上下方向に延設するフロントピラー６（図は左側のみ）が設けられている。このフロントピラー６はフロントピラーアウタ７とフロントピラーインナ８とから構成されており、フロントピラーアウタ７のフランジ部９，１０とフロントピラーインナ８の延設部１１及びフランジ部１２とを接合することで閉断面構造をなしている。なお、延設部１１はフランジ部９，１０，１２よりも車体前後方向の長さが長く形成されており、フロントピラーインナ８から車体前方に向けて延設されている。 On both sides of the dash panel 5, front pillars 6 (only the left side in the figure) extending in the vehicle body vertical direction are provided. The front pillar 6 includes a front pillar outer 7 and a front pillar inner 8, and the flange portions 9 and 10 of the front pillar outer 7 are joined to the extending portion 11 and the flange portion 12 of the front pillar inner 8. It has a closed cross-sectional structure. The extending portion 11 is formed to be longer in the longitudinal direction of the vehicle body than the flange portions 9, 10, and 12, and extends from the front pillar inner 8 toward the front of the vehicle body.

即ち、ダッシュパネル５はフランジ部５ｂにより、延設部１１の車幅方向内側の内面１１ａ間に接合されており、その車体前後方向前方に形成されるエンジンルーム３と後方に形成される車室１３とを隔てている。なお、図２に示すように、車室１３内に配置される乗員の脚部をＰと示す。   That is, the dash panel 5 is joined between the inner surface 11a on the vehicle width direction inner side of the extending portion 11 by the flange portion 5b, and the engine room 3 formed at the front in the vehicle body front-rear direction and the vehicle compartment formed at the rear. 13 is separated. In addition, as shown in FIG. 2, the passenger | crew's leg part arrange | positioned in the compartment 13 is shown as P. As shown in FIG.

一方、延設部１１の車幅方向外側の外面１１ｂには、板状のリンフォース１４の車幅方向内側の内面１４ａの後端が接合されている。その内面１４ａはストラットハウス４の車幅方向外壁上部に形成される接合部４ｂと接合されている。そして、リンフォース１４の車幅方向外側の外面１４ｂの前端には艤装部品を接合させる取付部１５が設けられており、外面１４ｂの上縁部及び下縁部には車幅方向外側に突出するフランジ部１６，１７が形成されると共に、その車体上下方向略中央部には車体前後方向に延設するリブ１８が形成されている。   On the other hand, a rear end of the inner surface 14a of the plate-like reinforcement 14 on the inner side in the vehicle width direction is joined to the outer surface 11b of the extending portion 11 on the outer side in the vehicle width direction. The inner surface 14 a is joined to a joint 4 b formed on the upper part of the outer wall in the vehicle width direction of the strut house 4. The front end of the outer surface 14b on the outer side in the vehicle width direction of the reinforcement 14 is provided with a mounting portion 15 for joining the fitting parts, and the upper edge portion and the lower edge portion of the outer surface 14b protrude outward in the vehicle width direction. Flange portions 16 and 17 are formed, and a rib 18 extending in the longitudinal direction of the vehicle body is formed at a substantially central portion in the vertical direction of the vehicle body.

即ち、ストラットハウス４は、その車幅方向内側においてサイドメンバ３に接合され、車幅方向外側においてリンフォース１４に接合され、車体前後方向後部においてダッシュパネル５に接合されることにより、高剛性化が図られている。また、リンフォース１４は、ストラットハウス４の接合部４ａとダッシュパネル５の接合部５ａとの接合部１９が内面１４ａの範囲内に配置されると共に、ストラットハウス４の上端４ｃがリブ１８と対向するように設けられている。つまり、トラットハウス４の上端４ｃ及び接合部１９の上部１９ａとリブ１８とは同じ高さに配置されている。 That is, the strut house 4 is joined to the side member 3 on the inner side in the vehicle width direction, joined to the reinforcement 14 on the outer side in the vehicle width direction, and joined to the dash panel 5 on the rear part in the vehicle body front-rear direction. Is planned. Further, the reinforcement 14, with the junction 19 between the bonding portion 5a of the joint portion 4a and the dash panel 5 struts house 4 is disposed within the inner surface 14a, the upper end 4c of the strut house 4 and a rib 18 facing It is provided to do. That is, the upper end 4c of the trat house 4 and the upper portion 19a of the joint portion 19 and the rib 18 are arranged at the same height.

リンフォース１４の形状や配置は上述した事項に限定されることはなく、フランジ１６，１７を設けなくても構わない。また、トラットハウス４の上端４ｃ及び接合部１９の上部１９ａはリブ１８と同じ高さに配置されていなくてもよく、内面１４ａに当接していればよい。なお、本実施例では、車体の左側（助手席側）について説明したが、右側（運転手席側）にも適用されることは言うまでもない。   The shape and arrangement of the reinforcement 14 are not limited to those described above, and the flanges 16 and 17 may not be provided. Moreover, the upper end 4c of the trat house 4 and the upper part 19a of the joining part 19 do not need to be arrange | positioned at the same height as the rib 18, and should just contact | abut to the inner surface 14a. In the present embodiment, the left side (passenger seat side) of the vehicle body has been described, but it goes without saying that the present invention is also applied to the right side (driver seat side).

従って、上述した構成をなすことにより、図１，２に示すように正面衝突により衝撃エネルギーＦが車体１に作用すると、サイドメンバ２とリンフォース１４とは車体後方へ座屈変形され、これに伴い、サイドメンバ２とリンフォース１４との間に介在するストラットハウス４も車体後方へ後退される。   1 and 2, when the impact energy F acts on the vehicle body 1 due to a frontal collision as shown in FIGS. 1 and 2, the side member 2 and the reinforcement 14 are buckled and deformed rearward of the vehicle body. Accordingly, the strut house 4 interposed between the side member 2 and the reinforcement 14 is also retracted rearward of the vehicle body.

ここで、ストラットハウス４及びダッシュパネル５の車幅方向外側において、高い剛性を有するストラットハウス４の上端４ｃ及びストラットハウス４とダッシュパネル５との接合部１９からフロントピラーインナ８に亘りリンフォース１４を設けているので、ストラットハウス４の後退を低減させることができ、ダッシュパネル５の車室１３内への侵入を防止することができる。また、従来の車体構造のようにリンフォースをフロントピラーとで閉断面構造にさせ、あるいはリンフォース自体を閉断面構造にさせことなく、リンフォース１４を板状に形成させると共に、フランジ部１６，１７及びリブ１８を設けて蛇腹状に形成させることにより、簡素な形状でありながらリンフォース１４の剛性を効率よく向上させ、衝撃エネルギーを吸収することができる。   Here, at the outer side in the vehicle width direction of the strut house 4 and the dash panel 5, the reinforcement 14 extends from the upper end 4 c of the strut house 4 having high rigidity and the joint 19 between the strut house 4 and the dash panel 5 to the front pillar inner 8. Therefore, the backward movement of the strut house 4 can be reduced, and the dash panel 5 can be prevented from entering the vehicle compartment 13. Further, as in the conventional vehicle body structure, the reinforcement is formed into a closed cross-sectional structure with the front pillar, or the reinforcement 14 is formed in a plate shape without forming the reinforcement itself into a closed cross-sectional structure, and the flange portion 16, By providing the bellows 17 and the ribs 18, the rigidity of the reinforcement 14 can be efficiently improved and the impact energy can be absorbed while having a simple shape.

即ち、ストラットハウス４の上端４ｃ近傍からフロントピラーインナ８までの間にリンフォース１４を設けることにより、最小限度の補強をするだけで、正面衝突時に作用する衝撃エネルギーを吸収することができる。これにより、ダッシュパネル５の車室１３内への侵入を防ぎ、乗員の脚部Ｐの保護を図ることができる。   That is, by providing the reinforcement 14 between the vicinity of the upper end 4 c of the strut house 4 and the front pillar inner 8, it is possible to absorb impact energy that acts during a frontal collision with only minimal reinforcement. Thereby, the penetration | invasion into the compartment 13 of the dash panel 5 can be prevented, and a passenger | crew's leg part P can be protected.

次に、車体１の組立工法について、図５乃至７を用いて説明する。   Next, an assembly method for the vehicle body 1 will be described with reference to FIGS.

図５に示すように、車体１の組み立ては、先ず、サイドメンバ２，ストラットハウス４及びリンフォース１４等からなるフレームＡＳＳＹ２０と、ダッシュパネル５及びフロントピラー６等からなるピラーＡＳＳＹ２１とを組み立てておき、次いで、そのフレームＡＳＳＹ２０とピラーＡＳＳＹ２１とを組み立てることにより行われる。   As shown in FIG. 5, the vehicle body 1 is assembled by first assembling a frame assembly 20 including the side member 2, the strut house 4 and the reinforcement 14, and a pillar assembly 23 including the dash panel 5 and the front pillar 6 and the like. Then, the frame assembly 20 and the pillar assembly 21 are assembled.

フレームＡＳＳＹ２０とピラーＡＳＳＹ２１との組み立ては、リンフォース１４間にピラーＡＳＳＹ２１を所定位置に配置させ、接合することで行われるが、このとき、フレームＡＳＳＹ２０側に接合されているリンフォース１４がピラーＡＳＳＹ２１の挿入時のガイドとなり、組み立てを容易に行うことができる。これにより、フレームＡＳＳＹ２０とピラーＡＳＳＹ２１との組み立て時のばらつきが低減されるので、車体１の組立精度が向上されることになる。 The assembly of the frame ASSY 20 and the pillar ASSY 21 is performed by arranging the pillar ASSY 21 at a predetermined position between the reinforcements 14 and joining them. At this time, the reinforcement 14 joined to the frame ASSY 20 side is connected to the pillar ASSY 21. It becomes a guide for insertion and can be easily assembled. Thereby, since the dispersion | variation at the time of the assembly of frame ASSY20 and pillar ASSY21 is reduced, the assembly precision of the vehicle body 1 will be improved.

更に、図６，７に示すように、車体１の組立完了後、車体１の前方において、フェンダーパネル２２を取付部１５に接合する場合においても、組立精度が向上された車体１側に接合するので、フェンダーパネル２２周辺の組み立て精度も向上される。仮に、フェンダーパネル２２等の何らかの不具合が発生したときでも、改修が容易に行えることができ、しかも、組立再現性あるいは復元性に優れので、作業者の経験を問う心配もない。   Further, as shown in FIGS. 6 and 7, after the assembly of the vehicle body 1 is completed, even when the fender panel 22 is bonded to the mounting portion 15 in front of the vehicle body 1, the vehicle 1 is bonded to the vehicle body 1 side with improved assembly accuracy. Therefore, the assembly accuracy around the fender panel 22 is also improved. Even if some troubles such as the fender panel 22 occur, the repair can be easily performed, and the assembly reproducibility or restoration is excellent, so that there is no concern about the operator's experience.

つまり、リンフォース１４を板状に形成することにより、一平面である内面１４ａ及び外面１４ｂを備えることができ、これに各部材を接合するようにしたので、車体１を簡素な構成にでき、衝撃エネルギーを効率よく吸収させるだけではなく、車体１の組立精度を向上させることができる。   That is, by forming the reinforcement 14 in a plate shape, the inner surface 14a and the outer surface 14b, which are one plane, can be provided, and each member is joined thereto, so that the vehicle body 1 can be configured simply. Not only can the impact energy be absorbed efficiently, but also the assembly accuracy of the vehicle body 1 can be improved.

従って、本発明に係る車体構造によれば、板状で車体前後方向に延設されると共に後端が車室１３の前部両端に接合されるリンフォース１４と、リンフォース１４の車幅方向内側に設けられるストラットハウス４と、ストラットハウス４の車体前後方向後方に設けられたダッシュパネル５とを備え、ストラットハウス４及びダッシュパネル５の車幅方向外側において、高い剛性を有するストラットハウス４の上端４ｃ及びストラットハウス４とダッシュパネル５との接合部１９からフロントピラーインナ８に亘りリンフォース１４を設けることにより、簡素な車体１の構成でありながらリンフォース１４の剛性を効率よく向上させ、良好な衝撃エネルギー吸収特性を保ちながら車体強度を補強することができる。しかも、車体１の組立を容易に行えることができるので、車体組立精度を向上させることができる。   Therefore, according to the vehicle body structure according to the present invention, the reinforcement 14 having a plate shape and extending in the longitudinal direction of the vehicle body and having the rear end joined to both ends of the front portion of the compartment 13, and the vehicle width direction of the reinforcement 14. The strut house 4 provided on the inner side and the dash panel 5 provided on the rear side in the vehicle body front-rear direction of the strut house 4 are provided, and the strut house 4 having high rigidity is provided on the outer side in the vehicle width direction of the strut house 4 and the dash panel 5. By providing the reinforcement 14 from the upper end 4c and the joint portion 19 between the strut house 4 and the dash panel 5 to the front pillar inner 8, the rigidity of the reinforcement 14 is efficiently improved while having a simple configuration of the vehicle body 1. Vehicle strength can be reinforced while maintaining good impact energy absorption characteristics. In addition, since the vehicle body 1 can be easily assembled, the vehicle body assembly accuracy can be improved.

また、リンフォース１４に車体前後方向に延設するリブ１８とフランジ部１６，１７とを形成させ、ストラットハウス４の上端４ｃ及び接合部１９の上部１９ａとリブ１８とを同じ高さに配置したことにより、リンフォース１４を蛇腹状に形成させることで容易に剛性を向上することができるので、高い剛性を有するストラットハウス４の上端４ｃ及び接合部１９の車体前後方向後方への後退を低減させることができ、ダッシュパネル５の車室１３内への侵入を防ぎ、乗員の脚部Ｐの保護を図ることができる。   Further, ribs 18 and flange portions 16 and 17 extending in the longitudinal direction of the vehicle body are formed on the reinforcement 14, and the upper end 4c of the strut house 4 and the upper portion 19a of the joint portion 19 and the ribs 18 are arranged at the same height. Accordingly, the rigidity can be easily improved by forming the reinforcement 14 in a bellows shape, and therefore, the backward movement of the upper end 4c of the strut house 4 and the joint portion 19 having high rigidity in the longitudinal direction of the vehicle body is reduced. Therefore, it is possible to prevent the dash panel 5 from entering the passenger compartment 13 and protect the passenger's legs P.

また、リンフォース１４の外面１４ｂに取付部１５を設けることにより、フェンダーパネル２２等の艤装部品周辺の組立精度も向上させることができ、改修も容易に行えることができ、組立再現性あるいは復元性を有することができる。   In addition, by providing the attachment portion 15 on the outer surface 14b of the reinforcement 14, the assembly accuracy around the fitting parts such as the fender panel 22 can be improved, the repair can be easily performed, and the assembly reproducibility or recoverability.
