Description

【0001】
【発明の属する技術分野】
本発明は、主にスクーター型の自動二輪車の給油部構造に関するものである。
【0002】
【従来の技術】
スクーター型の自動二輪車において、上方に開口する大容量の収納ボックスと、その後方に設けられた燃料の給油口とが、開閉可能な着座シートで覆われたものがある。着座シートは閉じた際にロック装置によりロックできるようになっている。
【0003】
このように収納ボックスと給油口を着座シートで覆うように構成すれば、給油口を覆う専用のリッドやロック装置等を設ける必要がなくなるため、給油口付近の構造を大幅に簡素化することができ、車体のコストダウンや重量軽減に大きく貢献できる。
【0004】
【発明が解決しようとする課題】
しかしながら、燃料給油の際には、着座シートを開放した状態にて給油口に給油ノズルを挿し込んで給油を行うため、給油口から燃料が溢れたり、飛び散ったりした際に収納ボックスの内部が燃料の付着により汚損される懸念があった。
【0005】
給油口の高さを収納ボックスの上部開口部より大幅に低くすれば、収納ボックス内部の汚損を回避することができるが、その反面、給油口のキャップの着脱が困難になるという別な問題点が発生する。
【0006】
本発明は、この問題を解決するためになされたものであり、給油時における収納ボックス内の汚損を防止するとともに、給油口のキャップの着脱性を損なうことがなく、しかも給油口下方付近の汚損を防止可能であり、かつ給油口から溢れた余剰油の排出性を向上させることのできる自動二輪車の給油部構造を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記目的を達成するため、本発明に係る自動二輪車の給油部構造は、請求項1に記載したように、上方に開口する収納ボックスの後方に給油口が配置され、上記収納ボックスの上部開口部と上記給油口とが開閉可能な着座シートで覆われた自動二輪車の給油部構造において、収納ボックスの上部開口部付近から後方に延出して下方に凹む形状の受け皿部を収納ボックスに一体形成し、この受け皿部の底部から給油口を上方に臨ませるとともに、少なくとも収納ボックスの上部開口部と給油口との間に介在する遮蔽板を受け皿部の底部から立ち上げるように設け、この遮蔽板の上端の高さを給油口上端および収納ボックスの上部開口部上端よりも高く設定し、上記遮蔽板の下部に第一ドレン孔を設けるとともに、上記受け皿部の底部に第二ドレン孔を設け、上記第二ドレン孔に下方へ延びるドレンホースを接続したことを特徴とする。
【0008】
このように自動二輪車の給油部構造を構成すれば、給油時に給油口から溢れたり飛び散った余剰油が遮蔽板により遮蔽されて収納ボックスの内部に入らなくなるため、収納ボックスの内部が汚損されなくなる。また、給油口から溢れた余剰油が第一ドレン孔と第二ドレン孔とドレンホースを経て速やかに外部に排出されるので余剰油の排出性が向上する。
【0012】
また、本発明に係る自動二輪車の給油部構造は、請求項2に記載したように、請求項1の構成において前記給油口を燃料給油口およびオイル給油口とし、前記第一ドレン孔を上記燃料給油口の近傍に設け、前記第二ドレン孔を上記オイル給油口の近傍に設けるとともに、第一ドレン孔から第二ドレン孔に向かって下方に傾斜するドレン溝を前記受け皿部の底部に形成したことを特徴とする。
【0013】
こうした場合、燃料給油口から溢れる等した余剰燃料は第一ドレン孔からドレン溝を流れて第二ドレン孔に流れ込み、オイル給油口から溢れる等した余剰オイルもドレン溝を流れて第二ドレン孔に流れ込むが、余剰燃料は余剰オイルよりも上流側からドレン溝に流れ込むため、ドレン溝に付着したオイル分が余剰燃料により洗い流される。このためドレン溝が清浄に保たれ、余剰燃料、余剰オイルの排出性が向上する。
【0014】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。図1は、本発明に係る給油部構造が適用された自動二輪車の一例を示す左側面図である。この自動二輪車1は例えばスクーター型であり、前輪2と後輪3との間に低床式のステップボード4が設けられ、その後方に設けられたリヤボディー5の上部に着座シート6が設置されている。リヤボディー5の下方にはパワーユニット7が設置され、後輪3はパワーユニット7の後部に直接軸支されている。
【0015】
図2はリヤボディー5、着座シート6、パワーユニット7、後輪3付近を拡大した左側面図であり、図3と図4はリヤボディー5の内部構造を示す斜視図である。リヤボディー5の内部では、車体フレームを構成する左右一対のフレームパイプ11,12の上方に収納ボックス13が設置され、収納ボックス13の後方には左側に燃料タンク14、右側にオイルタンク15が設置されている。そして、これらの部材が合成樹脂製のフレームカバー17により覆われ、フレームカバー17の最後部にテールランプ18とキャリア19が設けられている。
【0016】
図5にも示すように、収納ボックス13は、例えば強化樹脂等の素材により上方に開口する有底容器状に一体成型され、その前上部に形成されたシート取付部21に図示しないシートヒンジを介して着座シート6の前部が取り付けられる。着座シート6はシートヒンジを軸に図2中の矢印の方向に開放可能である。
【0017】
燃料タンク14上面の燃料給油口23とオイルタンク15上面のオイル給油口24は、それぞれ収納ボックス13の後方で左右に並ぶように配置されており、収納ボックス13の上部開口部13aと2つの給油口23,24が着座シート6で覆われる。着座シート6の後部はロック装置25(図1参照)により施錠可能であり、燃料やオイルの給油はロック装置25を解錠して着座シート6を開放した状態で行われる。
【0018】
図3〜図5に示すように、収納ボックス13には受け皿部27が一体形成されている。この受け皿部27は、収納ボックス13の上部開口部13aの後縁付近から後方に延出して下方に凹む形状に造形されている。受け皿部27の周壁27aの上端は、収納ボックス13の上部開口部13aの縁に形成されたシートレール13bにスムーズに続くように形成されており、着座シート6の閉塞時にはシートレール13bと周壁27aの上端に沿って着座シート6が被装される。
【0019】
受け皿部27の底部には、左側に燃料給油口貫通穴29が、右側にオイル給油口貫通穴30が開設されている。図6に示すように、燃料給油口貫通穴29には燃料タンク14の燃料給油口23が下方から上方に貫通し、オイル給油口貫通穴30にはオイルタンク15のオイル給油口24が同様に貫通し、これにより両給油口23,24が受け皿部27の底部から上方に臨む態様となっている。燃料給油口23にはフィラーキャップ31が螺合され、オイル給油口24にも図示しないゴムキャップが嵌め込まれる。なお、図3に示すように、耐油ゴム製のオイル給油口シール部材32が、オイル給油口24とオイル給油口貫通穴30との間の隙間を液密的にシールするように嵌合される。
【0020】
そして、受け皿部27には遮蔽板34が設けられている。この遮蔽板34は、収納ボックス13の上部開口部13aと燃料給油口23との間に介在するように、受け皿部27の底部から立ち上げるように設けられる。遮蔽板34の材質としては耐油性ゴム等の柔軟性に富んだものが好ましい。
【0021】
図7〜図9にも示すように、遮蔽板34は底面部35と一体に成型され、底面部35には環状の嵌合部36が一体成型され、この嵌合部36が受け皿部27の燃料給油口貫通穴29と燃料給油口23との間に液密的に嵌合される。遮蔽板34の上端の高さは、燃料給油口23の上端および収納ボックス13の上部開口部13aの上端よりも高く設定する必要がある。
【0022】
遮蔽板34の下部(燃料給油口23近傍)には第一ドレン孔38が設けられている。また、図4と図5に示すように、受け皿部27の底部には第二ドレン孔39が設けられている。この第二ドレン孔39はオイル給油口貫通穴30の近傍(オイル給油口24近傍)に配置されており、受け皿部27の下方からドレンホース40が接続されている。ドレンホース40は下方へ延びるように配設され、他端が外部に開放されている。
【0023】
また、受け皿部27の底部にはドレン溝41が形成されている。このドレン溝41は、例えば受け皿部27の前縁付近にて、遮蔽板34の第一ドレン孔38付近から第二ドレン孔39に向かって延び、かつ第一ドレン孔38から第二ドレン孔39に向かって下方に傾斜するように形成されている。
【0024】
以上のように構成された給油部構造において、燃料の給油時には、着座シート6を開放し、燃料給油口23のフィラーキャップ31を取り外し、給油ノズルを燃料給油口23に挿し込んで給油を行う。
【0025】
その際に燃料給油口23から燃料が溢れたり飛び散ったりしても、この余剰な燃料は遮蔽板34により遮蔽されて収納ボックス13の内部に入らないため、給油時に収納ボックス13の内部が燃料の付着により汚損される懸念がない。
【0026】
遮蔽板34は弾性材料により柔軟に形成されているため、フィラーキャップ31の着脱性が損なわれることがない。したがって、遮蔽板34を高く形成することができ、これにより収納ボックス13内の汚損防止効果を向上させることができる。場合によっては着座シート6を閉じた時に遮蔽板34が着座シート6の底部に干渉するまで遮蔽板34の高さを高めることもできる。しかも、遮蔽板34を燃料給油口23に近付けて設けることができるため、燃料給油口23回りのコンパクト性を向上させることもできる。
【0027】
また、遮蔽板34の底面部35に一体成型された環状の嵌合部36が、受け皿部27の燃料給油口貫通穴29と燃料給油口23との間に液密的に嵌合されるため、燃料給油口23から溢れた余剰燃料が嵌合部36によりシールされる。このため、余剰燃料が受け皿部27と燃料給油口23との間から下方に流れ落ちて燃料タンク14付近を汚損してしまう懸念がない。
【0028】
燃料給油口23から溢れた余剰燃料は、遮蔽板34の下部に形成された第一ドレン孔38を経てドレン溝41を流れ、第二ドレン孔39とドレンホース40を経て速やかに外部に排出される。また、オイル給油口24からオイルが溢れた場合も、この余剰オイルはドレン溝41と第二ドレン孔39とドレンホース40を経て外部に排出される。よって、余剰燃料や余剰オイルの排出性が良い。
【0029】
第一ドレン孔38は燃料給油口23の近傍となるように遮蔽板34の下部に設けられ、第二ドレン孔39はオイル給油口24の近傍となるように受け皿部27に設けられ、ドレン溝41は第一ドレン孔38から第二ドレン孔39に向かって下方に傾斜するように受け皿部27に形成されているため、余剰燃料は余剰オイルよりも上流側からドレン溝41に流れ込むことになる。
【0030】
燃料はオイルよりも低粘度である上にオイルを溶かす溶剤性があるため、ドレン溝41やドレンホース40にオイル分が付着していても、このオイル分は燃料により洗い流される。このため、ドレン溝41やドレンホース40が清浄に保たれ、余剰燃料、余剰オイル等の廃油の排出性が向上する。
【0031】
ところで、本実施形態では遮蔽板34が燃料給油口23の前側のみを囲むように設けられているが、例えば燃料給油口23を全周に亘って囲むように遮蔽板34を設けたり、燃料給油口23とオイル給油口24の両方を囲むように遮蔽板34を設けてもよい。
【0032】
また、ドレンホース40の自由端を開放せずにキャニスター等に接続することにより、燃料の外部流出を防止して低公害化を実現することができる。
【0033】
なお、この給油部構造の構成は、上方に開口する収納ボックス(収納部)に隣接して給油口が配置されたものであれば、スクーター型に限らず他の形態の自動二輪車(車両)にも幅広く適用することができる。
【0034】
【発明の効果】
以上説明したように、本発明に係る自動二輪車の給油部構造によれば、上方に開口する収納ボックスの後方に給油口が配置され、上記収納ボックスの上部開口部と上記給油口とが開閉可能な着座シートで覆われた自動二輪車において、給油時における収納ボックス内の汚損を防止するとともに、給油口のキャップの着脱性を損なうことがなく、しかも給油口下方付近の汚損を防止可能であり、かつ給油口から溢れた余剰油の排出性を向上させることができる。

BACKGROUND OF THE INVENTION
The present invention mainly relates to a fueling part structure of a scooter type motorcycle.
[0002]
[Prior art]
In some scooter type motorcycles, a large-capacity storage box that opens upward and a fuel filler port provided behind the storage box are covered with a seat that can be opened and closed. The seating seat can be locked by a locking device when closed.
[0003]
If the storage box and the filler port are covered with the seating seat in this way, it is not necessary to provide a dedicated lid or lock device that covers the filler port, so the structure near the filler port can be greatly simplified. This can greatly contribute to cost reduction and weight reduction of the car body.
[0004]
[Problems to be solved by the invention]
However, when refueling, the refueling nozzle is inserted into the refueling port with the seating seat open, and refueling is performed. There was a concern that it would be fouled by the adhesion of.
[0005]
If the height of the filler opening is made significantly lower than the upper opening of the storage box, the inside of the storage box can be avoided, but on the other hand, it is difficult to attach and detach the filler cap. Will occur.
[0006]
The present invention has been made to solve this problem, and prevents the inside of the storage box from being polluted during refueling, does not impair the detachability of the cap of the filling port, and is also stained near the bottom of the filling port. It is an object of the present invention to provide a fueling part structure for a motorcycle that can prevent the oil leakage and improve the discharge performance of excess oil overflowing from the fueling port.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the fueling part structure for a motorcycle according to the present invention is characterized in that, as described in claim 1, a fueling opening is disposed behind a storage box that opens upward, and an upper opening part of the storage box. In addition, in the fueling part structure of the motorcycle covered with a seat that can be opened and closed, the tray part is formed integrally with the storage box and extends backward from the vicinity of the upper opening of the storage box and is recessed downward. The refueling port faces upward from the bottom of the saucer, and at least a shielding plate interposed between the upper opening of the storage box and the refueling port is provided to rise from the bottom of the saucer . the height of the upper end is set higher than the upper opening upper end of the fuel supply port top and the storage box, provided with a first drain hole at the bottom of the shielding plate, the second drain to the bottom of the saucer section The hole is provided, characterized in that connecting the drain hose extending downwardly to the second drain hole.
[0008]
If the oil supply part structure of the motorcycle is configured in this way, excess oil that overflows or splatters from the oil supply port during refueling is shielded by the shielding plate and does not enter the storage box, so that the interior of the storage box is not soiled. Moreover, since the excess oil overflowing from the oil supply port is quickly discharged to the outside through the first drain hole, the second drain hole, and the drain hose, the discharge performance of the excess oil is improved.
[0012]
Further, the oil supply portion structure of the motorcycle according to the present invention, as described in claim 2, the fuel supply port and the fuel filler opening and the oil filler opening in the configuration of claim 1, said fuel said first drain hole Provided in the vicinity of the oil filler port, the second drain hole is provided in the vicinity of the oil filler port, and a drain groove inclined downward from the first drain hole toward the second drain hole is formed in the bottom portion of the tray part. It is characterized by that.
[0013]
In such a case, surplus fuel overflowing from the fuel filler port flows into the second drain hole through the first drain hole, and surplus oil overflowing from the oil filler port also flows into the second drain hole through the drain groove. Although it flows in, the surplus fuel flows into the drain groove from the upstream side of the surplus oil, so that the oil adhering to the drain groove is washed away by the surplus fuel. For this reason, the drain groove is kept clean, and the discharge performance of surplus fuel and surplus oil is improved.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a left side view showing an example of a motorcycle to which a fueling portion structure according to the present invention is applied. The motorcycle 1 is, for example, a scooter type, and a low-floor type step board 4 is provided between a front wheel 2 and a rear wheel 3, and a seating seat 6 is installed on an upper part of a rear body 5 provided behind the step board 4. ing. A power unit 7 is installed below the rear body 5, and the rear wheel 3 is directly supported by the rear portion of the power unit 7.
[0015]
FIG. 2 is an enlarged left side view of the vicinity of the rear body 5, seating seat 6, power unit 7, and rear wheel 3. FIGS. 3 and 4 are perspective views showing the internal structure of the rear body 5. FIG. Inside the rear body 5, a storage box 13 is installed above the pair of left and right frame pipes 11, 12 constituting the body frame, a fuel tank 14 is installed on the left side, and an oil tank 15 is installed on the right side behind the storage box 13. Has been. These members are covered with a synthetic resin frame cover 17, and a tail lamp 18 and a carrier 19 are provided at the rearmost portion of the frame cover 17.
[0016]
As shown in FIG. 5, the storage box 13 is integrally formed in a bottomed container shape that is opened upward by a material such as reinforced resin, for example, and a seat hinge (not shown) is attached to the seat mounting portion 21 formed in the front upper portion thereof. The front part of the seating seat 6 is attached via. The seat 6 can be opened in the direction of the arrow in FIG. 2 around the seat hinge.
[0017]
The fuel supply port 23 on the upper surface of the fuel tank 14 and the oil supply port 24 on the upper surface of the oil tank 15 are arranged so as to be lined up left and right behind the storage box 13, respectively, and the upper opening 13a of the storage box 13 and the two fuel supply ports The mouths 23 and 24 are covered with the seating seat 6. The rear portion of the seating seat 6 can be locked by a locking device 25 (see FIG. 1), and fuel or oil is supplied in a state where the locking device 25 is unlocked and the seating seat 6 is opened.
[0018]
As shown in FIGS. 3 to 5, the receiving box portion 27 is integrally formed with the storage box 13. The tray portion 27 is shaped in a shape that extends rearward from the vicinity of the rear edge of the upper opening 13a of the storage box 13 and is recessed downward. The upper end of the peripheral wall 27a of the tray part 27 is formed so as to smoothly follow the seat rail 13b formed at the edge of the upper opening 13a of the storage box 13, and when the seating seat 6 is closed, the seat rail 13b and the peripheral wall 27a are formed. The seating seat 6 is covered along the upper end.
[0019]
At the bottom of the tray part 27, a fuel filler opening through hole 29 is formed on the left side, and an oil filler opening through hole 30 is opened on the right. As shown in FIG. 6, the fuel filler port 23 of the fuel tank 14 penetrates the fuel filler port through hole 29 from the lower side to the upper side, and the oil filler port 24 of the oil tank 15 similarly penetrates the oil filler port through hole 30. Through this, both the fuel filler ports 23 and 24 face upward from the bottom of the tray part 27. A filler cap 31 is screwed into the fuel filler port 23, and a rubber cap (not shown) is also fitted into the oil filler port 24. As shown in FIG. 3, the oil filler seal member 32 made of oil-resistant rubber is fitted so as to liquid-tightly seal the gap between the oil filler port 24 and the oil filler port through hole 30. .
[0020]
The receiving tray 27 is provided with a shielding plate 34. The shielding plate 34 is provided so as to rise from the bottom of the tray 27 so as to be interposed between the upper opening 13 a of the storage box 13 and the fuel filler opening 23. The material of the shielding plate 34 is preferably a material having high flexibility such as oil-resistant rubber.
[0021]
As shown in FIGS. 7 to 9, the shielding plate 34 is molded integrally with the bottom surface portion 35, and an annular fitting portion 36 is integrally molded on the bottom surface portion 35. A liquid-tight fitting is made between the fuel filler opening through hole 29 and the fuel filler opening 23. The height of the upper end of the shielding plate 34 needs to be set higher than the upper end of the fuel filler opening 23 and the upper end of the upper opening 13 a of the storage box 13.
[0022]
A first drain hole 38 is provided in the lower part of the shielding plate 34 (in the vicinity of the fuel filler opening 23). As shown in FIGS. 4 and 5, a second drain hole 39 is provided at the bottom of the tray part 27. The second drain hole 39 is disposed in the vicinity of the oil supply port through hole 30 (in the vicinity of the oil supply port 24), and a drain hose 40 is connected from below the tray part 27. The drain hose 40 is disposed so as to extend downward, and the other end is open to the outside.
[0023]
A drain groove 41 is formed at the bottom of the tray part 27. The drain groove 41 extends, for example, from the vicinity of the first drain hole 38 of the shielding plate 34 toward the second drain hole 39 near the front edge of the tray portion 27, and from the first drain hole 38 to the second drain hole 39. It is formed so as to be inclined downward.
[0024]
In the fuel supply portion structure configured as described above, when fuel is supplied, the seat 6 is opened, the filler cap 31 of the fuel supply port 23 is removed, and the fuel supply nozzle is inserted into the fuel supply port 23 to supply fuel.
[0025]
Even if fuel overflows or scatters from the fuel filler port 23 at this time, the excess fuel is shielded by the shielding plate 34 and does not enter the storage box 13. There is no concern of fouling by adhesion.
[0026]
Since the shielding plate 34 is formed flexibly with an elastic material, the detachability of the filler cap 31 is not impaired. Therefore, the shielding plate 34 can be formed high, thereby improving the antifouling effect in the storage box 13. In some cases, the height of the shielding plate 34 can be increased until the shielding plate 34 interferes with the bottom of the seating seat 6 when the seating seat 6 is closed. In addition, since the shielding plate 34 can be provided close to the fuel filler 23, the compactness around the fuel filler 23 can be improved.
[0027]
In addition, the annular fitting portion 36 that is integrally molded with the bottom surface portion 35 of the shielding plate 34 is liquid-tightly fitted between the fuel supply port through hole 29 and the fuel supply port 23 of the tray portion 27. Excess fuel overflowing from the fuel filler port 23 is sealed by the fitting portion 36. For this reason, there is no fear that surplus fuel will flow down from between the tray part 27 and the fuel filler opening 23 and contaminate the vicinity of the fuel tank 14.
[0028]
Excess fuel overflowing from the fuel filler port 23 flows through the drain groove 41 through the first drain hole 38 formed in the lower part of the shielding plate 34, and is quickly discharged to the outside through the second drain hole 39 and the drain hose 40. The Further, even when the oil overflows from the oil supply port 24, the excess oil is discharged to the outside through the drain groove 41, the second drain hole 39, and the drain hose 40. Therefore, the discharge property of surplus fuel and surplus oil is good.
[0029]
The first drain hole 38 is provided in the lower part of the shielding plate 34 so as to be in the vicinity of the fuel supply port 23, and the second drain hole 39 is provided in the tray part 27 so as to be in the vicinity of the oil supply port 24, and the drain groove 41 is formed in the tray part 27 so as to incline downward from the first drain hole 38 toward the second drain hole 39, so surplus fuel flows into the drain groove 41 from the upstream side of the surplus oil. .
[0030]
Since the fuel has a lower viscosity than the oil and has a solvent property to dissolve the oil, even if the oil component adheres to the drain groove 41 or the drain hose 40, the oil component is washed away by the fuel. For this reason, the drain groove 41 and the drain hose 40 are kept clean, and the discharge performance of waste oil such as surplus fuel and surplus oil is improved.
[0031]
By the way, in this embodiment, the shielding plate 34 is provided so as to surround only the front side of the fuel supply port 23. For example, the shielding plate 34 is provided so as to surround the fuel supply port 23 over the entire circumference, or the fuel supply is performed. A shielding plate 34 may be provided so as to surround both the port 23 and the oil supply port 24.
[0032]
Further, by connecting the drain hose 40 to a canister or the like without opening the free end of the drain hose 40, it is possible to prevent the fuel from flowing out and to reduce pollution.
[0033]
In addition, the structure of this fueling part structure is not limited to the scooter type, as long as the fueling port is disposed adjacent to the storage box (storing part) that opens upward. Can also be widely applied.
