Description

本発明は、燃料給油装置に関し、樹脂製のフィラーネックとねじ部とガン案内部材を有する燃料給油装置に関する。   The present invention relates to a fuel supply apparatus, and more particularly to a fuel supply apparatus having a resin filler neck, a threaded portion, and a gun guide member.

燃料給油装置は、燃料タンクへ燃料を導く燃料パイプが繋がっており、給油ガンが挿入される箇所の装置である。燃料給油時以外は、通常、燃料キャップが燃料給油装置のシール部材に螺合されている。   The fuel refueling device is a device at a location where a fuel pipe for guiding fuel to a fuel tank is connected and a fueling gun is inserted. The fuel cap is usually screwed into the seal member of the fuel supply device except during fuel supply.

現在、燃料給油装置も質量の削減と形状の自由度の向上から、金属製から樹脂製にすることが主流となってきている。しかし、給油ガンのノズル部は金属製であるため、燃料給油装置も給油ガンと接触する箇所、開口縁フランジ２１の燃料キャップとシールするシール部と、燃料キャップと螺着するねじ部であるネジ突起２２は、金属製で設けられている(例えば、特許文献１)。   At present, from the viewpoint of reducing the mass and improving the degree of freedom of the shape of the fuel refueling apparatus, it has become the mainstream to change from a metal to a resin. However, since the nozzle portion of the fueling gun is made of metal, the fuel fueling device also comes into contact with the fueling gun, a seal portion that seals the fuel cap of the opening edge flange 21, and a screw that is a screw portion that is screwed to the fuel cap. The protrusion 22 is made of metal (for example, Patent Document 1).

特許第３７５９９８１号Japanese Patent No. 3759981

しかし、上記のような金属製のねじ部は、複雑な形状であり、プレス加工した場合に、ねじ部が薄肉になるため加工の精度が求められており、工数や労力を要していた。そのため、ねじ部を樹脂で作製されることが検討されていた。この場合、ねじ部を樹脂で作製すると燃料による膨潤によってねじ部の寸法が変化してしまい、燃料キャップとねじ部の間に隙間が生じてしまうことも考えられた。   However, the metal screw portion as described above has a complicated shape, and when it is pressed, the screw portion becomes thin, so that processing accuracy is required, and man-hours and labor are required. Therefore, it has been studied that the screw portion is made of resin. In this case, when the screw portion is made of resin, the size of the screw portion is changed due to swelling by the fuel, and it is considered that a gap is generated between the fuel cap and the screw portion.

本発明は、上記の課題を踏まえ、ねじ部の寸法変化を抑えることができる燃料給油装置を提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a fuel supply device that can suppress a change in dimensions of a threaded portion.

[適用例１]
車両の給油口に取り付けられる燃料給油装置であって、車両外部と燃料タンクとを接続する接続路の開口部を形成する開口形成部を有する樹脂製のフィラーネックと、上記開口形成部の内周側に燃料キャップとシールするシール部と、該シール部より屈曲形成され、該開口形成部の外周に配置される外周部とからなり、該開口形成部の上記開口部の周辺に装着される金属製のシール部材と、上記接続路内に配置され、給油ガンを案内する導入孔を形成し、該導入孔の内周側に上記燃料キャップが装着されるためのねじ部を有している円筒部を有する、樹脂製のガン案内部材と、を備え、上記外周部は、軸方向断面において、軸垂直方向に上記ねじ部の外周側を覆っていることを特徴とする。 [Application Example 1]
A fuel refueling device attached to a fuel filler port of a vehicle, wherein a resin filler neck having an opening forming portion that forms an opening portion of a connection path connecting the outside of the vehicle and a fuel tank, and an inner periphery of the opening forming portion A seal part that seals with the fuel cap on the side, and an outer peripheral part that is bent from the seal part and disposed on the outer periphery of the opening forming part, and is attached to the periphery of the opening part of the opening forming part A cylinder having a seal member made of metal and a screw portion that is disposed in the connection path, forms an introduction hole that guides the fuel gun, and is attached to the fuel cap on the inner peripheral side of the introduction hole A resin-made gun guide member, and the outer peripheral portion covers the outer peripheral side of the screw portion in the axial vertical direction in the axial cross section.

その他の適用例として、上記ガン案内部材は、上記シール部の内周端と上記円筒部の上端部が当接し、上記円筒部の下方に、上記フィラーネックの内周壁により保持される保持部を有し、該保持部は、上記開口形成部のネック縮径部にならう縮径部、または、上記開口形成部の内周壁と係合する爪部からなるものを適用できる。   As another application example, in the gun guide member, an inner peripheral end of the seal portion and an upper end portion of the cylindrical portion are in contact, and a holding portion held by an inner peripheral wall of the filler neck is provided below the cylindrical portion. The holding portion may be formed of a reduced diameter portion that follows the neck reduced diameter portion of the opening forming portion or a claw portion that engages with the inner peripheral wall of the opening forming portion.

適用例１によれば、金属製のシール部材の外周部が、樹脂製のフィラーネックの開口形成部の外周、および、軸断面において、軸垂直方向に間接的にガン案内部材のねじ部も覆っているため、燃料によるガン案内部材およびフィラーネックの開口形成部の外径方向への膨潤を、ねじ部の外周側の金属製のシール部材の外周部で抑えることができるため、ねじ部の膨潤による変形が生じにくく、燃料キャップとねじ部の間に隙間や干渉が生じにくい。また、給油ガン挿入時や、車外側からの部材によりねじ部周辺の開口部傷つきを防止することができる。   According to the application example 1, the outer peripheral portion of the metal seal member also covers the outer periphery of the opening portion of the resin filler neck and the screw portion of the gun guide member indirectly in the axial direction in the axial cross section. Therefore, swelling of the gun guide member and the filler neck opening forming portion due to the fuel in the outer diameter direction can be suppressed by the outer peripheral portion of the metal seal member on the outer peripheral side of the screw portion. It is difficult for deformation to occur, and gaps and interference are less likely to occur between the fuel cap and the screw portion. Further, it is possible to prevent the opening portion around the screw portion from being damaged when the fuel gun is inserted or by a member from the outside of the vehicle.

その他適用例によれば、ガン案内部材は、シール部材の内周端と当接し、燃料タンク側へ向けては、ガン案内部材の縮径部がフィラーネックのネック縮径部で保持されるか、爪部がフィラーネックの内周壁と係合し、軸方向で挟持されることでガン案内部材は、簡単な構造で組みつけられ、省スペース化することができる。   According to other application examples, the gun guide member is in contact with the inner peripheral end of the seal member, and whether the reduced diameter portion of the gun guide member is held by the neck reduced diameter portion of the filler neck toward the fuel tank side. Since the claw portion engages with the inner peripheral wall of the filler neck and is clamped in the axial direction, the gun guide member can be assembled with a simple structure and space can be saved.

以下、本発明の一実施の形態を実施例に基づいて説明する。   Hereinafter, an embodiment of the present invention will be described based on examples.

図１は、燃料給油装置１０が燃料タンクＦＴに組付けられている概略構成図である。燃料給油装置１０は、車外側（本明細書においては、燃料キャップＦＣから燃料タンクＦＴへ向かう方向と逆の方向をいう）から燃料を燃料タンクＦＴに供給する燃料供給通路１０Ｐを形成するように、フィラーネック２０と、樹脂製の燃料パイプ５０と、タンク接続部材６０によって、主に構成されている。   FIG. 1 is a schematic configuration diagram in which a fuel refueling device 10 is assembled to a fuel tank FT. The fuel refueling device 10 forms a fuel supply passage 10P that supplies fuel to the fuel tank FT from the outside of the vehicle (in this specification, the direction opposite to the direction from the fuel cap FC toward the fuel tank FT). The filler neck 20, the resin fuel pipe 50, and the tank connecting member 60 are mainly configured.

フィラーネック２０の車外側には、燃料キャップＦＣが、シール部材３０と、樹脂製のガン案内部材４０に螺合され装着されている。燃料を車外から燃料タンクＦＴに供給する場合は、燃料キャップＦＣを取り外し、シール部材３０に給油ガンのノズルを給油可能となる位置まで挿入して、燃料を供給する。この場合に、フィラーネック２０の内周側に配置されたガン案内部材４０に給油ガンのノズルがあたりながら案内される。   On the vehicle exterior side of the filler neck 20, a fuel cap FC is screwed and attached to the seal member 30 and the resin gun guide member 40. When fuel is supplied to the fuel tank FT from the outside of the vehicle, the fuel cap FC is removed, and the nozzle of the fuel gun is inserted into the seal member 30 to a position where fuel can be supplied to supply the fuel. In this case, the nozzle of the fuel supply gun is guided while hitting the gun guide member 40 arranged on the inner peripheral side of the filler neck 20.

図２は、燃料給油装置の断面図である。図３は、燃料給油装置の分解斜視図である。フィラーネック２０は、ＨＤＰＥ（高密度ポリエチレン）などの樹脂製で、車外と燃料タンクＦＴを接続する接続路２１を形成する開口形成部２２、ネック縮径部２３、本体形成部２４と、管接続部２５の順で車外側から形成されている。本体形成部２４は、開口形成部２２より外径および内径とも小さく、開口形成部２２から本体形成部２４へ徐々に径が小さくなるように連続形成されている。管接続部２５は、本体形成部２４より外径および内径とも小さく、本体形成部と連続成形されおり、外周には、燃料パイプ５０が圧入される複数の環状突部２５ａを有している。管接続部２５の先端に、燃料パイプ５０に燃料が流出する流出孔２６が形成されている。   FIG. 2 is a cross-sectional view of the fuel supply apparatus. FIG. 3 is an exploded perspective view of the fuel supply device. The filler neck 20 is made of resin such as HDPE (high density polyethylene), and has an opening forming portion 22 that forms a connection path 21 that connects the outside of the vehicle and the fuel tank FT, a neck reduced diameter portion 23, a main body forming portion 24, and a pipe connection. It is formed from the vehicle outer side in the order of the portion 25. The main body forming part 24 is formed continuously so that the outer diameter and the inner diameter are smaller than the opening forming part 22 and the diameter gradually decreases from the opening forming part 22 to the main body forming part 24. The pipe connecting portion 25 has an outer diameter and an inner diameter smaller than the main body forming portion 24, is continuously formed with the main body forming portion, and has a plurality of annular protrusions 25a into which the fuel pipe 50 is press-fitted on the outer periphery. An outflow hole 26 through which fuel flows out to the fuel pipe 50 is formed at the tip of the pipe connection portion 25.

開口形成部２２は、開口形成本体２２ａと、開口形成本体２２ａより外径がやや小さい溶着部２７を有している。溶着部２７の車外側の端部は、開口部２８を形成している開口端２８ａとなっている。溶着部２７の外周壁には、軸方向に伸びるリブ２７ａが周方向に複数一体成形されており、開口形成本体２２ａと溶着部２７との境界の段差である受部２７ｂから開口端２８ａの手前まで伸びている。リブ２７ａは、後述するシール部材３０との組付け後のがたつきを防止する。 The opening forming part 22 has an opening forming main body 22a and a welding part 27 having an outer diameter slightly smaller than that of the opening forming main body 22a. An end portion on the vehicle outer side of the welded portion 27 is an opening end 28 a forming an opening portion 28. A plurality of ribs 27a extending in the axial direction are integrally formed on the outer peripheral wall of the welded portion 27 in the circumferential direction. From the receiving portion 27b, which is a step at the boundary between the opening forming body 22a and the welded portion 27, to the front of the opening end 28a. It extends to. The ribs 27a prevent rattling after assembly with a seal member 30 described later.

シール部材３０は、ＳＵＳ（ステンレス）などの金属製であり、内周側で燃料タンクＦＴ側に向けて傾斜し環状に突出している面状のシール部３１を有している。シール部３１は、給油ガンの挿入される注入孔３２を形成している。シール部３１の先端には、注入孔３２の軸方向で燃料タンクＦＴに向けてシール部３１から屈曲している内周端３３が形成されている。シール部３１の外周に、フィラーネック２０の溶着部２７の外径と略同一の環状の外周部３４が、車外側から軸方向に略Ｕ字形状で屈曲形成されている。フィラーネック２０の開口端２８ａの内周側をシール部３１、外周側を外周部３４配置され開口端２８ａを覆っている。外周部３４の端部の外周端３５は、フィラーネック２０の受部２７ｂに当接している。外周端３５は、内周端３３より軸方向で燃料タンクＦＴへむけて大きく形成されている。 The seal member 30 is made of metal such as SUS (stainless steel), and has a planar seal portion 31 that is inclined toward the fuel tank FT side on the inner peripheral side and protrudes in an annular shape. The seal part 31 forms an injection hole 32 into which a fuel gun is inserted. An inner peripheral end 33 that is bent from the seal portion 31 toward the fuel tank FT in the axial direction of the injection hole 32 is formed at the tip of the seal portion 31. On the outer periphery of the seal portion 31, an annular outer peripheral portion 34 that is substantially the same as the outer diameter of the welded portion 27 of the filler neck 20 is bent and formed in a substantially U shape in the axial direction from the vehicle outer side. An inner peripheral side of the opening end 28a of the filler neck 20 is disposed on the sealing portion 31 and an outer peripheral portion 34 is disposed on the outer peripheral side to cover the opening end 28a. The outer peripheral end 35 at the end of the outer peripheral portion 34 is in contact with the receiving portion 27 b of the filler neck 20. The outer peripheral end 35 is formed larger than the inner peripheral end 33 in the axial direction toward the fuel tank FT.

ガン案内部材４０は、ＰＯＭ（ポリアセタール）またはＰＡ（ポリアミド）などの樹脂製で、図２に示すとおり、導入孔４１を形成する第１円筒部４２、第１縮径部４３、第２円筒部４４、第２縮径部４５、第３円筒部４６からなる。第２円筒部４４は、第１円筒部より、外径および内径とも小さく第１縮径部４３により連続して形成されている。第３円筒部４６は、第２円筒部４４よりも外径および内径とも小さく第２縮径部４５より連続して形成されており、給油ガン挿入時に給油ガンを保持できる導出孔４７が形成されている。第１円筒部４２は、内周側に燃料キャップＦＣと螺摘するためのねじ部４８を有している。 The gun guide member 40 is made of a resin such as POM (polyacetal) or PA (polyamide), and as shown in FIG. 2, the first cylindrical portion 42, the first reduced diameter portion 43, and the second cylindrical portion that form the introduction hole 41. 44, a second reduced diameter portion 45, and a third cylindrical portion 46. The second cylindrical portion 44 has a smaller outer diameter and inner diameter than the first cylindrical portion, and is continuously formed by the first reduced diameter portion 43. The third cylindrical portion 46 has a smaller outer diameter and inner diameter than the second cylindrical portion 44 and is continuously formed from the second reduced diameter portion 45, and a lead-out hole 47 is formed that can hold the fuel gun when the fuel gun is inserted. ing. The first cylindrical portion 42 has a screw portion 48 for screwing with the fuel cap FC on the inner peripheral side.

ガン案内部材４０の第１円筒部４２、第１縮径部４３および第２円筒部４４のそれぞれの外径は、ガン案内部材４０がフィラーネック２０の内部に摺動して挿入装着できる程度に、フィラーネック２０の開口形成部２２、ネック縮径部２３および本体形成部２４の内径とほぼ同一、または、やや小さく設定されている。そして、ガン案内部材４０は、第１縮径部４３がネック縮径部２３により軸方向で燃料タンクＦＴ側に挿入を防止されることで、保持されている。第１円筒部４２の上端部４２ａが、シール部材３０の内周端３３が対応して軸方向で当接することで、車外側へガン案内部材４０が抜けることを防止している。   The outer diameter of each of the first cylindrical portion 42, the first reduced diameter portion 43, and the second cylindrical portion 44 of the gun guide member 40 is such that the gun guide member 40 can be inserted into the filler neck 20 by sliding. The inner diameter of the opening forming portion 22, the neck reduced diameter portion 23, and the main body forming portion 24 of the filler neck 20 is set to be substantially the same or slightly smaller. The gun guide member 40 is held by preventing the first reduced diameter portion 43 from being inserted into the fuel tank FT in the axial direction by the neck reduced diameter portion 23. The upper end portion 42a of the first cylindrical portion 42 is in contact with the inner peripheral end 33 of the seal member 30 in the axial direction, thereby preventing the gun guide member 40 from coming out to the vehicle exterior side.

第２円筒部４４には爪部４９が外径方向へ突出するように形成されており、フィラーネック２０の本体形成部２４の内周側に設けられた凹部または突部などに係合することでガン案内部材４０を、保持するとともに、周方向への回転止めも行うことができる。 A claw portion 49 is formed on the second cylindrical portion 44 so as to protrude in the outer diameter direction, and engages with a recess or a protrusion provided on the inner peripheral side of the main body forming portion 24 of the filler neck 20. Thus, the gun guide member 40 can be held and can be prevented from rotating in the circumferential direction.

シール部材３０の外周部３４は、ガン案内部材４０のねじ部４８の軸方向の断面において、軸垂直方向で外周を覆うように組みつけられている。本明細書において、軸方向とは、図２に示すフィラーネック２０の接続路２１の軸に対する方向をいう。シール部材３０の固定は、外周部３４、または、溶着部２７を超音波や熱板などで加熱することで、溶着部２７を溶融し、シール部材３０と溶着部２７を接着している。   The outer peripheral portion 34 of the seal member 30 is assembled so as to cover the outer periphery in the axial vertical direction in the cross section in the axial direction of the threaded portion 48 of the gun guide member 40. In this specification, an axial direction means the direction with respect to the axis | shaft of the connection path 21 of the filler neck 20 shown in FIG. The sealing member 30 is fixed by heating the outer peripheral portion 34 or the welded portion 27 with ultrasonic waves or a hot plate to melt the welded portion 27 and bond the seal member 30 and the welded portion 27 together.

上述した構成により、以下の効果を得ることができる。金属製のシール部材３０の外周部３４が、ガン案内部材４０の外周側を覆うため、衝撃で外周側から金属片が飛んできても開口部２８に大きな破損が生じにくい。また、ねじ部４８が樹脂で作製されているため、燃料によって膨潤する可能性があったが、ねじ部４８の外周を金属製の外周部３４が覆っているため、膨潤によるねじ部４８の変形を防ぐことができる。   With the configuration described above, the following effects can be obtained. Since the outer peripheral portion 34 of the metal seal member 30 covers the outer peripheral side of the gun guide member 40, even if a metal piece flies off from the outer peripheral side due to an impact, the opening 28 is not easily damaged. In addition, since the screw portion 48 is made of resin, there is a possibility that the screw portion 48 may swell due to the fuel. Can be prevented.

また、ガン案内部材４０は、上端部４２ａを軸方向で車外側からシール部材３０の内周端３３が当接し、第１縮径部４３を内径側に傾斜しているネック縮径部２３が軸方向で燃料タンクＦＴの方向から受けることで、ガン案内部材４０を軸方向で、簡単に保持することができる。なお、燃料タンクＦＴの方向への脱落防止の保持は、ネック縮径部２３ではなく、ガン案内部材４０の爪部４９がフィラーネック２０の本体形成部２４と係合することで行うこともできる。シール部材３０の外周端３５もフィラーネック２０の受部２７ｂと当接し、安定してシール部材３０も組みつけられる。   Further, the gun guide member 40 has a neck reduced diameter portion 23 in which the inner peripheral end 33 of the seal member 30 comes into contact with the upper end portion 42a in the axial direction from the vehicle outer side and the first reduced diameter portion 43 is inclined toward the inner diameter side. By receiving from the direction of the fuel tank FT in the axial direction, the gun guide member 40 can be easily held in the axial direction. The holding of the fuel tank FT in the direction of dropping off can also be performed by engaging the claw portion 49 of the gun guide member 40 with the main body forming portion 24 of the filler neck 20 instead of the neck reduced diameter portion 23. . The outer peripheral end 35 of the seal member 30 is also in contact with the receiving portion 27b of the filler neck 20, and the seal member 30 is assembled stably.

さらには、シール部材３０には、ねじ部が形成されておらず、簡単な構造とすることができるため、燃料キャップＦＣとシールするシール部３１の精度の高い平面度を形成することができ、複雑な形状ではないため加工費も低減することができる。   Furthermore, since the threaded portion is not formed on the seal member 30 and can have a simple structure, the flatness of the seal portion 31 that seals with the fuel cap FC can be formed with high accuracy. Since the shape is not complicated, the processing cost can be reduced.

なお、この発明は、上記実施例に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能である。例えば、ガン案内部材４０の爪部４９が第２円筒部４４に設けられているが、第１円筒部４２に設けても良い。   In addition, this invention is not restricted to the said Example, It is possible to implement in a various aspect in the range which does not deviate from the summary. For example, the claw portion 49 of the gun guide member 40 is provided in the second cylindrical portion 44, but may be provided in the first cylindrical portion 42.
