Description

本発明は、車両の外壁に形成した給油用の開口部とその内部に配備された燃料補給用のフューエルパイプとの間に配備される車両のフューエルアダプタ取付構造に関する。   The present invention relates to a fuel adapter mounting structure for a vehicle that is disposed between a fuel supply opening formed in an outer wall of a vehicle and a fuel pipe for fuel supply disposed therein.

車両は燃料補給用のフューエルパイプを車体側部の外壁に設けた給油用の開口部内に収容し、その開口部をフューエルリッドで開放可能に閉鎖する。開口部の内部には、フューエルパイプの先端部がフューエルリッドと干渉することがないように配備され、その給油口がフューエルキャップで閉鎖された状態で収容される。
ここで、車両の外壁に形成した開口部に対し、その内側である車室側には剛性強化部材である内壁部材が対向配備され、その内壁部材との干渉を避けた状態で燃料補給用のフューエルパイプが配備され、その先端がフューエルアダプタの内部に貫通状態で収容される。 The vehicle houses a fuel pipe for refueling in an opening for refueling provided on the outer wall of the vehicle body side, and the opening is closed so as to be openable by a fuel lid. Inside the opening, the front end of the fuel pipe is disposed so as not to interfere with the fuel lid, and the fuel filler opening is accommodated in a state of being closed by the fuel cap.
Here, with respect to the opening formed in the outer wall of the vehicle, an inner wall member, which is a rigidity enhancing member, is disposed opposite to the inner side of the passenger compartment, and is used for refueling while avoiding interference with the inner wall member. A fuel pipe is provided, and the tip of the fuel pipe is accommodated in the fuel adapter in a penetrating state.

ここで、フューエルアダプタ（樹脂カップ）１１０は、図７（ａ）に示すように、開口側の外周フランジ１００と底壁部１０１とそれらを結ぶ周壁１０２とを有した深皿状を成す。その底壁部１０１には貫通穴１０４が形成され、そこにフューエルパイプが嵌挿される。
図７（ｂ）に示すように、車両の外壁１２０に設けた開口部１２１は外壁面より内側である車室側に屈曲する段部１２２を延出形成し、その先端を開口中央側に向けて屈曲して延出させる環状の内周フランジ１２３を形成する。この内周フランジ１２３にフューエルアダプタ１１０の外周フランジ１００を係合し、フューエルアダプタ１１０の底壁部１０１をこれと対向する内壁部材１３０側にねじ止めすることで、フューエルアダプタ１１０を車両の外壁１２０の開口部１２１とその内側の内壁部材１３０の間に保持することができる。 Here, as shown in FIG. 7A, the fuel adapter (resin cup) 110 has a deep dish shape having an outer peripheral flange 100 on the opening side, a bottom wall portion 101, and a peripheral wall 102 connecting them. A through hole 104 is formed in the bottom wall portion 101, and a fuel pipe is fitted therein.
As shown in FIG. 7 (b), the opening 121 provided in the outer wall 120 of the vehicle extends and forms a stepped portion 122 that is bent toward the passenger compartment side that is inside the outer wall surface, and its tip is directed toward the center of the opening. An annular inner peripheral flange 123 that is bent and extended is formed. The outer peripheral flange 100 of the fuel adapter 110 is engaged with the inner peripheral flange 123, and the bottom wall portion 101 of the fuel adapter 110 is screwed to the inner wall member 130 facing the fuel adapter 110, whereby the fuel adapter 110 is attached to the outer wall 120 of the vehicle. It can hold | maintain between the opening part 121 of this and the inner wall member 130 of the inner side.

この場合、図８（ａ）に示すように、フューエルアダプタ１１０の先端には、外周フランジ１００とその内側の弾性爪１０５とが外側に突き出し形成され、これらが外壁１２０の内周フランジ１２３の両面を挟持することで外壁面とフューエルアダプタ１１０の外周フランジ１００との開口方向Ｚの隙間ｔ１のずれを排除している。更に、図７（ｂ）に示す内周フランジ１２３の複数個所に設けた切り欠き１２４に対して、図７（ａ）に示す、フューエルアダプタ（樹脂カップ）１１０の周壁１０２の上部に形成した複数の膨出部１０５が嵌合することで、段部１２２と外周フランジ１００との隙間（合い沿い部隙間）ｔ２のばらつきの発生を防止している。   In this case, as shown in FIG. 8A, the outer peripheral flange 100 and the elastic claw 105 on the inner side protrude from the front end of the fuel adapter 110, and these are formed on both surfaces of the inner peripheral flange 123 of the outer wall 120. The gap t1 in the opening direction Z between the outer wall surface and the outer peripheral flange 100 of the fuel adapter 110 is eliminated. Further, a plurality of notches 124 provided at a plurality of locations on the inner peripheral flange 123 shown in FIG. 7B are formed on the upper portion of the peripheral wall 102 of the fuel adapter (resin cup) 110 shown in FIG. The bulging portion 105 is fitted to prevent the gap t2 between the stepped portion 122 and the outer peripheral flange 100 from occurring.

しかしながら、フューエルリッドの開口のように小さな開口において段部１２２と内周フランジ１２３とを連続して一体で成型するのは、難しく、切欠きなどの位置決め構造の設定が困難であった。
そこで、外壁１２０の開口１２１を小さくかつ位置決め構造を設定するために、図８（ｂ）に示すように、車両の外壁１２０の開口部１２１を囲む段部１２２の下端裏側に別部材の補強枠１３０を溶着し、その補強枠１３０で内周フランジ１２３を形成する構成をとる場合があった。これにより外壁面とフューエルアダプタ１１０の外周フランジ１００との開口方向Ｚの隙間ｔ１の調整を容易化し、外壁１２０の開口部１２１の回りの剛性強化を図り、開口部１２１の小型化を可能としている。 However, it is difficult to continuously and integrally form the stepped portion 122 and the inner peripheral flange 123 in a small opening such as an opening of a fuel lid, and it is difficult to set a positioning structure such as a notch.
Therefore, in order to make the opening 121 of the outer wall 120 small and set the positioning structure, as shown in FIG. 8B, a reinforcing frame as a separate member is provided on the back side of the lower end of the step 122 surrounding the opening 121 of the outer wall 120 of the vehicle. In some cases, the inner peripheral flange 123 is formed with the reinforcing frame 130 by welding 130. This facilitates the adjustment of the gap t1 in the opening direction Z between the outer wall surface and the outer peripheral flange 100 of the fuel adapter 110, enhances the rigidity around the opening 121 of the outer wall 120, and enables the opening 121 to be downsized. .

なお、特許文献１には車体外壁に形成した窪み部内に内周フランジ状の開口部を形成し、その開口部にカップ状のフューエルアダプタ１を嵌め込み、その端部の外周フランジ状の補強部を重ねて固着する。この際、フューエルアダプタ１の外周フランジ状の補強部の近傍で周方向に分散して複数の係止爪が形成される。この係止爪７の山型部が内周フランジ状の開口部を弾性変位して乗り越えることで、係止爪７と外周フランジ状の補強部とで内周フランジ状の開口部２１を挟持し、フューエルアダプタ１の抜け止めを行なっている。   In Patent Document 1, an inner flange-shaped opening is formed in a recess formed in the outer wall of the vehicle body, a cup-shaped fuel adapter 1 is fitted into the opening, and an outer flange-shaped reinforcing portion at the end is provided. It adheres repeatedly. At this time, a plurality of locking claws are formed in the circumferential direction in the vicinity of the outer peripheral flange-shaped reinforcing portion of the fuel adapter 1. The mountain-shaped portion of the locking claw 7 elastically displaces and climbs over the inner peripheral flange-shaped opening, so that the inner peripheral flange-shaped opening 21 is sandwiched between the locking claw 7 and the outer peripheral flange-shaped reinforcing portion. The fuel adapter 1 is prevented from coming off.

しかし、図８（ａ），（ｂ）に示す従来例のように、フューエルアダプタ１１０の先端の外周フランジ１００と弾性爪１０５とが挟持する外壁開口の内周フランジ１２３や、特許文献１に記載のフューエルアダプタの外周フランジ状補強部とその近傍の係止爪とが挟持する外壁開口の内周フランジ状開口部では、いずれも開口中央側に延びる内周フランジとして形成されている。
しかし、これら内周フランジは開口面積を狭めることとなり、開口の小型化を図る上で問題となっている。 However, as in the conventional example shown in FIGS. 8A and 8B, the inner peripheral flange 123 of the outer wall opening sandwiched between the outer peripheral flange 100 and the elastic claw 105 at the tip of the fuel adapter 110, and Patent Document 1 are described. The outer peripheral flange-shaped reinforcing portion of the fuel adapter and the inner peripheral flange-shaped opening of the outer wall opening sandwiched between the engaging claws in the vicinity thereof are each formed as an inner peripheral flange extending toward the center of the opening.
However, these inner peripheral flanges narrow the opening area, which is a problem in reducing the size of the opening.

更に、図８（ａ）に示すように、美観確保を図るため、段部１２２と外周フランジ１００との隙間（合い沿い部隙間）ｔ２のばらつきの発生を抑える手段を形成する場合、これがコストアップを招いてしまう。
更に、図８（ｂ）に示すように、段部１２２に補強枠１３０を溶着した場合、部品数が増え、部品費や組み付け工数増を招き、これがコストアップを招いてしまい、改善が望まれている。 Further, as shown in FIG. 8A, in order to ensure aesthetic appearance, when a means for suppressing the occurrence of a variation in the gap t2 between the stepped portion 122 and the outer peripheral flange 100 (a gap along the mating portion) is formed, this increases the cost. Will be invited.
Furthermore, as shown in FIG. 8B, when the reinforcing frame 130 is welded to the stepped portion 122, the number of parts increases, leading to an increase in parts costs and assembly man-hours. ing.

本発明は以上のような課題に基づきなされたもので、目的とするところは、コスト増を招くことなく、美観を損なわずに開口部の小型化を図れる車両のフューエルアダプタ取付構造を提供することにある。   The present invention has been made on the basis of the above problems, and an object thereof is to provide a fuel adapter mounting structure for a vehicle that can reduce the size of the opening without deteriorating the aesthetic appearance without causing an increase in cost.

一方、フューエルアダプタ７はその周壁１３の給油開口６側における４つの角部より湾曲係止爪１８をそれぞれ突設する。この湾曲係止爪１８は平面視で湾曲片状を成すようにして突き出し量ａ３（図４参照）だけ突き出し形成される。そして、段部８０１の内の所定量ａ１（＜ａ２）凹設される湾曲凹部８０２に、相互の弾性変位を用いて嵌合可能に形成され、同湾曲凹部８０２を閉鎖して美観確保を図れる。
隣り合う一対の湾曲係止爪１８の間には区画隙間ｔｓ（図５参照）を介して長片状の重合片１１を周壁１３の上端より弾性絞り部１９を介して突設している。
この弾性絞り部１９は、図６（ａ）に示すように、自由状態において、周壁１３の上端より、重合片１１を弾性変位可能（視矢ｄ方向）に直状に突き出し、自由状態に復帰する習性を保持する。 On the other hand, the fuel adapter 7 has curved locking claws 18 projecting from four corners of the peripheral wall 13 on the oil supply opening 6 side. The curved locking claws 18 are projected and formed by a projecting amount a3 (see FIG. 4) so as to form a curved piece in plan view. The curved recess 802, which is recessed by a predetermined amount a1 (<a2) in the step 801, is formed so as to be able to be fitted using mutual elastic displacement, and the curved recess 802 can be closed to ensure aesthetic appearance. .
Between the pair of adjacent curved locking claws 18, a long piece of overlapping piece 11 is projected from the upper end of the peripheral wall 13 via an elastic restricting portion 19 via a partition gap ts (see FIG. 5).
As shown in FIG. 6 (a), the elastic restricting portion 19 protrudes straight from the upper end of the peripheral wall 13 so as to be elastically displaceable (in the direction of the arrow d) from the upper end of the peripheral wall 13, and returns to the free state. Keep the habit to do.

この弾性復帰力の働きで、外側フランジを成す重合片１１は段部８０１の下端縁に弾性押圧力を加えて段部８０１と連結状態を保持している。
次に、このようなフューエルアダプタ７を給油開口６内に組み付ける手順を説明する。 ここで、フューエルアダプタ７をリヤフェンダー５に形成された給油開口６と車体側の内壁部材１６の間に差し込む。
この場合、図６（ａ）、（ｂ）に示すように、弾性絞り部１９は、自由状態において周壁１３の上端より、断面視において、重合片１１を弾性変位可能（視矢ｄ方向）に直状に突き出し、弾性変形部１７は自由状態での突き出し量Ｈ０を保持している。
次いで、図６（ｂ）に示すように、フューエルアダプタ７を内壁部材１６側に向けて押圧Ｐ０して、弾性変形部１７をＵ字型のまま強く湾曲させ、基端ｂ１から突き出し端ｂ２までの突き出し量Ｈ１を狭め、重合片１１の位置を下方に弾性変位させる。 Due to the action of the elastic restoring force, the superposed piece 11 constituting the outer flange applies an elastic pressing force to the lower end edge of the step portion 801 and keeps the connected state with the step portion 801.
Next, a procedure for assembling such a fuel adapter 7 in the oil supply opening 6 will be described. Here, the fuel adapter 7 is inserted between the oil supply opening 6 formed in the rear fender 5 and the inner wall member 16 on the vehicle body side.
In this case, as shown in FIGS. 6 (a) and 6 (b), the elastic restricting portion 19 is capable of elastically displacing the overlapping piece 11 in the cross-sectional view from the upper end of the peripheral wall 13 in the free state (in the direction of the arrow d). Protruding in a straight line, the elastically deforming portion 17 maintains the protruding amount H0 in the free state.
Next, as shown in FIG. 6B, the fuel adapter 7 is pressed P0 toward the inner wall member 16, and the elastically deforming portion 17 is strongly curved while being U-shaped, from the base end b1 to the protruding end b2. The protruding amount H1 is narrowed, and the position of the superposed piece 11 is elastically displaced downward.

その上で、周壁１３と共に弾性変形部１７を給油開口６を拡大する方向ｅに押し込む。これにより弾性絞り部１９が弾性変位し、重合片１１が段部８０１の下端縁を潜り抜け（視矢ｄ方向）、図６（ｂ）に実線で示すように、段部８０１の下端縁に重合片１１が当接した状態に達し、弾性絞り部１９による弾性力で、その状態が保持される。
この後、図６（ｃ）に示すように、フューエルアダプタ７を内壁部材１６側に向けて押圧する力Ｐ０を解除すると、弾性変形部１７が弾性復帰変位Ｒ０し、基端ｂ１から突き出し端ｂ２までの突き出し量Ｈ２を増加させる。これに応じて周壁１３が開口側である段部８０１側に移動し、弾性絞り部１９の弾性復帰変位力が加わり、段部８０１の下端縁に重合片１１が強く当接し、圧接状態となって、フューエルアダプタ７を内壁部材１６とリヤフェンダー５の間に確実に保持する。なお、この状態で、フューエルアダプタ７とリヤフェンダー５の当接部には不図示のシール材が塗布され、両者の間のシール性確保や、見栄えの改善を行なっている。 Then, the elastic deformation part 17 is pushed together with the peripheral wall 13 in the direction e of enlarging the oil supply opening 6. As a result, the elastic throttle part 19 is elastically displaced, and the overlapping piece 11 passes through the lower end edge of the step part 801 (in the direction of the arrow d), and as shown by the solid line in FIG. The superposed piece 11 reaches a contacted state, and the state is maintained by the elastic force of the elastic restricting portion 19.
Thereafter, as shown in FIG. 6C, when the force P0 that presses the fuel adapter 7 toward the inner wall member 16 is released, the elastic deformation portion 17 undergoes the elastic return displacement R0, and protrudes from the base end b1 to the protruding end b2. The protrusion amount H2 is increased. In response to this, the peripheral wall 13 moves to the stepped portion 801 side, which is the opening side, and an elastic return displacement force of the elastic restricting portion 19 is applied. Thus, the fuel adapter 7 is securely held between the inner wall member 16 and the rear fender 5. In this state, a sealing material (not shown) is applied to the contact portion between the fuel adapter 7 and the rear fender 5 to ensure the sealing property between them and improve the appearance.

この場合、開口フランジである段部８０１の外側端を環状に配列された複数の重合片１１が覆うように嵌め込まれ、段部８０１の下端縁に重合片１１が弾性絞り部１９の弾性復帰変位力の働きで弾性的に圧接する。このため、確実に段部８０１に重合片１１を連結できる。
特に、図６（ｃ）に示すように、段部８０１の下端縁に重合片１１が当接した状態を保持するので、フューエルアダプタ７の環状開口端側の周壁１３の内径ｒ１と、開口周縁部の開口フランジである段部８０１の内径ｒ２との間の差分を少なくできる。このため、リヤフェンダー５の外壁部８に形成される給油開口６の小型化を図れる。 In this case, the outer end of the stepped portion 801 that is an opening flange is fitted so as to cover a plurality of overlapping pieces 11 arranged in a ring shape, and the overlapping piece 11 is elastically displaced by the lower end edge of the stepped portion 801. It is elastically pressed by the action of force. For this reason, the superposition | polymerization piece 11 can be connected with the step part 801 reliably.
In particular, as shown in FIG. 6C, since the overlapping piece 11 is kept in contact with the lower end edge of the step portion 801, the inner diameter r1 of the peripheral wall 13 on the annular opening end side of the fuel adapter 7 and the opening periphery The difference between the inner diameter r2 of the step portion 801 that is the opening flange of the portion can be reduced. For this reason, size reduction of the oil supply opening 6 formed in the outer wall part 8 of the rear fender 5 can be achieved.

更に、フューエルアダプタ７の底壁部１２に形成した弾性変形部１７が内壁部材１６側に押圧されることで、フューエルアダプタ７が接合面１６１側に変位する際に、重合片１１が段部８０１を潜り抜けることを容易化できる。しかも弾性変形部１７から受ける反力を重合片１１より段部８０１の下端縁に加えることで、より確実にフューエルアダプタ７をリヤフェンダー５と内壁部材１６の間に確実に保持できる。
上述のところで、フューエルリッド１及びフューエルアダプタの給油開口６は略矩形をなすものとしたが、その他の多角形状のフューエルリッド及びフューエルアダプタの給油開口を形成しても良く、この場合も図１の車両のフューエルアダプタ取付構造とほぼ同様の作用、効果が得られる。 Furthermore, when the elastic deformation part 17 formed in the bottom wall part 12 of the fuel adapter 7 is pressed to the inner wall member 16 side, when the fuel adapter 7 is displaced to the joining surface 161 side, the overlapping piece 11 is stepped 801. It is easy to get through. Moreover, by applying the reaction force received from the elastic deformation portion 17 to the lower end edge of the stepped portion 801 from the superposed piece 11, the fuel adapter 7 can be more reliably held between the rear fender 5 and the inner wall member 16.
In the above description, the fuel lid 1 and the fuel adapter oil supply opening 6 are substantially rectangular, but other polygonal fuel lids and fuel adapter oil supply openings may be formed. Actions and effects similar to those of the fuel adapter mounting structure can be obtained.
