従来から、車両のフロアパネルの下面側に車両前後方向に沿って延びるフューエルチューブが取り付けられ、このフューエルチューブを耐チップ保護板によって下方から覆う車両の配管プロテクターが知られている（例えば、特許文献１参照）。
実公平４−１０３２３３号公報 2. Description of the Related Art Conventionally, a vehicle pipe protector in which a fuel tube extending along the vehicle front-rear direction is attached to the lower surface side of a vehicle floor panel and the fuel tube is covered from below with a chip-resistant protective plate is known (for example, Patent Documents). 1).
Japanese Utility Model Publication No. 4-103233

ところで、上述の配管プロテクターでは、耐チップ保護板の前端部が開口しており、車両前方から飛んでくる小石等がフューエルチューブと耐チップ保護板との間に入ってしまうおそれがあった。   By the way, in the above-mentioned piping protector, the front end portion of the chip-resistant protective plate is open, and there is a possibility that pebbles or the like flying from the front of the vehicle may enter between the fuel tube and the chip-resistant protective plate.

特に、フューエルチューブに直線部分よりも比較的脆弱な折り返した部分（折返部）がある場合では、下方から覆う構成の耐チップ保護板によってこの折返部を十分に保護できないおそれが生じていた。   In particular, when the fuel tube has a folded portion (folded portion) that is relatively weaker than the straight portion, there is a possibility that the folded portion cannot be sufficiently protected by the chip protection plate configured to cover from below.

そこでこの発明は、管部材の折返部を簡易な構成で保護することができる車両の配管取付構造を提供することを課題としている。   Then, this invention makes it the subject to provide the piping attachment structure of the vehicle which can protect the folding | returning part of a pipe member by simple structure.

上記課題を解決するために、本発明は、車両のフロアパネルの下面側に取付手段を介して車両前後方向に延びる管部材を取り付ける車両の配管取付構造であって、前記管部材は、少なくとも一部に折返部を有すると共に、この折返部の先端部を車両前方に向け、前記フロアパネルは、前記折返部の先端部の前側に位置し且つ下方に突出した突出部を有していることを特徴としている。   In order to solve the above-described problems, the present invention provides a vehicle pipe mounting structure in which a pipe member extending in the vehicle front-rear direction is attached to a lower surface side of a vehicle floor panel via mounting means, and the pipe member includes at least one pipe member. The folding panel has a folded portion, the front end portion of the folded portion faces the front of the vehicle, and the floor panel has a protruding portion that is located on the front side of the leading end portion of the folded portion and projects downward. It is a feature.

このように構成された本発明によると、管部材の折返部が突出部よりも車両後方に位置することとなるので、車両前方から飛んでくる小石等はフロアパネルよりも下方に突出した突出部に当たり、管部材の折返部に当たることが防止される。これにより、管部材の折返部を簡易な構成で保護することが可能となる。   According to the present invention configured as described above, since the folded portion of the pipe member is located behind the projecting portion, the pebbles flying from the front of the vehicle project below the floor panel. In this case, it is prevented from hitting the folded portion of the pipe member. Thereby, it is possible to protect the folded portion of the pipe member with a simple configuration.

次に、本発明に係る車両の配管取付構造を実施するための最良の形態を図面に基づいて説明する。   Next, the best mode for carrying out a vehicle pipe mounting structure according to the present invention will be described with reference to the drawings.

図１に示す車両１の配管取付構造は、フロアパネル２の下面２ａ側に複数の取付部材（取付手段）１０を介して取り付けられた管部材を備えている。   The pipe mounting structure of the vehicle 1 shown in FIG. 1 includes a pipe member that is attached to the lower surface 2 a side of the floor panel 2 via a plurality of mounting members (attaching means) 10.

この実施の形態では、エンジン（図示せず）とフューエルタンク３とを連通させる燃料パイプに適用した場合を示している。   In this embodiment, the case where it applies to the fuel pipe which connects an engine (not shown) and the fuel tank 3 is shown.

この燃料パイプは、フューエルタンク３からエンジンに燃料を供給する供給側パイプＺと、エンジンからフューエルタンク３に燃料を戻すリターンパイプ（以下、パイプという）２０（管部材）とからなり、両者はパイプ径が異なる。   This fuel pipe is composed of a supply side pipe Z for supplying fuel from the fuel tank 3 to the engine, and a return pipe (hereinafter referred to as a pipe) 20 (pipe member) for returning the fuel from the engine to the fuel tank 3. The diameter is different.

このパイプ２０は、車両前方（図１において矢印ＦＲで示す上側）に配置された図示しないエンジンに一端が連結され、他端がフューエルタンク３に連結されている。パイプ２０のエンジンとフューエルタンク３との間には、エンジンから車両後方に向かって直線状に延びた直線部Ｘと、パイプ２０を蛇行させて燃料の流通を迂回させ、エンジンによって加熱された燃料を冷却する迂回部Ｙとが設けられている。   The pipe 20 has one end connected to an engine (not shown) arranged in front of the vehicle (the upper side indicated by the arrow FR in FIG. 1) and the other end connected to the fuel tank 3. Between the engine of the pipe 20 and the fuel tank 3, a straight portion X extending linearly from the engine toward the rear of the vehicle and the fuel heated by the engine by causing the pipe 20 to meander to bypass the flow of fuel. And a detour part Y for cooling.

パイプ２０の迂回部Ｙは、エンジンより延設されたパイプ２０が、フューエルタンク３の前側で車幅方向に沿って屈曲し、後述するトンネル部４を乗り越えた後に、再び屈曲して車両前方に向かって延在され、さらに、車両後方に向かって折り返される。そしてさらに、フューエルタンク３の前側で再び車両前方に向かって折り返し、これまでの配設経路の内側に沿うように延設され、再びトンネル部４を乗り越え、屈曲して車両後方に向かい、他端がフューエルタンク３に連結されている。   The bypass portion Y of the pipe 20 is bent along the vehicle width direction on the front side of the fuel tank 3 after the pipe 20 extending from the engine, and after bending over the tunnel portion 4 to be described later, it is bent again to the front of the vehicle. It extends toward the rear and is further turned back toward the rear of the vehicle. Further, it is folded back toward the front of the vehicle again at the front side of the fuel tank 3 and extends along the inner side of the arrangement path so far, over the tunnel portion 4 and bent again toward the rear of the vehicle, and the other end. Is connected to the fuel tank 3.

また、車両前方に向かって延在されたパイプ２０を車両後方に折り返した部分が折返部２１となり、この折返部２１は先端部が車両前方に向いている。すなわち、折返部２１の外側が車両前方側に位置し、内側が車両後方側に位置している。   Moreover, the part which turned the pipe 20 extended toward the vehicle front back to the vehicle back turns into the folding | returning part 21, and this folding | returning part 21 has the front-end | tip part facing the vehicle front. That is, the outer side of the folded portion 21 is located on the vehicle front side, and the inner side is located on the vehicle rear side.

フロアパネル２は、車両１の車室Ｒ（図２及び図５参照）の下側に配置されるパネル部材であり、車幅方向中央部に設けられると共に車両前後方向に延びるトンネル部４と、車幅方向両側部に設けられると共に車両前後方に延びる一対のサイドシル部５と、トンネル部４及びサイドシル部５の間に設けられると共に車両前後方向に延びる一対のサイドメンバ６とを有している。   The floor panel 2 is a panel member disposed on the lower side of the vehicle compartment R (see FIGS. 2 and 5) of the vehicle 1, and is provided at the center in the vehicle width direction and extends in the vehicle front-rear direction. It has a pair of side sill parts 5 provided on both sides in the vehicle width direction and extending in the front-rear direction of the vehicle, and a pair of side members 6 provided between the tunnel part 4 and the side sill part 5 and extending in the vehicle front-rear direction. .

なお、サイドメンバ６は、フロアパネル２の上側（車室Ｒ内側）に設けられた断面ほぼハット形状のインナメンバ６ａと、フロアパネル２の下側（車室Ｒ外側）に設けられた断面ほぼハット形状のアウタメンバ６ｂとを有している。   The side member 6 includes an inner member 6a having a substantially hat-shaped cross section provided on the upper side of the floor panel 2 (inside the vehicle compartment R) and a substantially cross-sectional hat provided on the lower side of the floor panel 2 (outside the vehicle compartment R). And an outer member 6b having a shape.

さらに、このフロアパネル２の下面２ａ側には、補助パネル（突出部）７が取り付けられている。   Further, an auxiliary panel (protruding portion) 7 is attached to the lower surface 2 a side of the floor panel 2.

この補助パネル７は、パイプ２０の折返部２１の先端部の前側近傍に位置すると共に、図２に示すように、前端部及び後端部がフロアパネル２に固着され、中間部が下方に膨出している。これにより、この補助パネル７がフロアパネル２よりも下方に突出することとなる。   The auxiliary panel 7 is located in the vicinity of the front side of the front end portion of the folded portion 21 of the pipe 20, and as shown in FIG. 2, the front end portion and the rear end portion are fixed to the floor panel 2, and the intermediate portion swells downward. I'm out. Thereby, this auxiliary panel 7 protrudes below the floor panel 2.

また、この補助パネル７は、車幅方向の一方の側部７ａがトンネル部４に接続され、車幅方向の他方の端部７ｂが一方のサイドシル部５に接続されている（図１及び図５参照）。これにより、トンネル部４と一方のサイドシル部５とは補助パネル７を介して連結されることとなる。なお、サイドメンバ６は、補助パネル７を貫通している。   The auxiliary panel 7 has one side portion 7a in the vehicle width direction connected to the tunnel portion 4 and the other end portion 7b in the vehicle width direction connected to one side sill portion 5 (FIGS. 1 and 5). Thereby, the tunnel part 4 and the one side sill part 5 are connected via the auxiliary panel 7. The side member 6 passes through the auxiliary panel 7.

さらに、この補助パネル７よりも車両前方側にフロアパネル２を挟んで一対の前輪（図示せず）が配置され、フューエルタンク３よりも車両後方側にフロアパネル２を挟んで一対の後輪（図示せず）が配置されている。   Further, a pair of front wheels (not shown) are arranged with the floor panel 2 sandwiched in front of the auxiliary panel 7 with the floor panel 2 interposed therebetween, and a pair of rear wheels (with the floor panel 2 sandwiched between the fuel tank 3 and the vehicle rear side). (Not shown) is arranged.

複数の取付部材１０は、パイプ２０の直線部Ｘを支持する第一取付部材１０Ａと、パイプ２０の迂回部Ｙを支持する第二取付部材１０Ｂと、迂回部Ｙの折返部２１を支持する第三取付部材１０Ｃとを有している。   The plurality of attachment members 10 support a first attachment member 10 </ b> A that supports the straight portion X of the pipe 20, a second attachment member 10 </ b> B that supports the bypass portion Y of the pipe 20, and a first portion that supports the folded portion 21 of the bypass portion Y. And three attachment members 10C.

第一取付部材１０Ａと第二取付部材１０Ｂとは、後述するブラケット部１２の形状は共通であるが、後述する管支持部１１の形状が異なり、第二取付部材１０Ｂと第三取付部材１０Ｃとは、管支持部１１は共通であるがブラケット部１２の形状が異なるので、ここでは第三取付部材１０Ｃについて詳細に説明する。   The first mounting member 10A and the second mounting member 10B have the same shape of the bracket portion 12 described later, but the shape of the tube support portion 11 described later is different, and the second mounting member 10B and the third mounting member 10C Since the pipe support portion 11 is common but the shape of the bracket portion 12 is different, the third mounting member 10C will be described in detail here.

第三取付部材１０Ｃは、図３に示すように、パイプ２０を支持可能な複数の支持凹部（支持面）１１Ａが形成された管支持部１１と、この管支持部１１をフロアパネル２に固定するブラケット部（固定部）１２とを有している。   As shown in FIG. 3, the third mounting member 10 </ b> C has a tube support portion 11 formed with a plurality of support recesses (support surfaces) 11 </ b> A capable of supporting the pipe 20, and the tube support portion 11 is fixed to the floor panel 2. And a bracket portion (fixed portion) 12.

図４に示す管支持部１１は、弾力性を有する耐熱樹脂によって直方体形状に形成され、ここでは４箇所の支持凹部１１Ａが長手方向に並んでいる。   The tube support portion 11 shown in FIG. 4 is formed in a rectangular parallelepiped shape by a heat-resistant resin having elasticity, and here, four support concave portions 11A are arranged in the longitudinal direction.

各支持凹部１１Ａは、パイプ２０の外周面に沿う円弧形状を呈しており、上方に向かって開放する挿入口１１Ｂを有している。この挿入口１１Ｂは、開放端１１Ｂａに向うにつれて次第に開口幅が広がっており、パイプ２０を挿入しやすいようになっている。また、挿入口１１Ｂの始端１１Ｂｂの幅Ｔ１は、パイプ２０の外径よりも幅狭になっており、挿入されたパイプ２０が容易に抜けないようなっている。 Each support recess 11 </ b> A has an arc shape along the outer peripheral surface of the pipe 20, and has an insertion port 11 </ b> B that opens upward. The insertion port 11B has an opening width that gradually increases toward the open end 11Ba so that the pipe 20 can be easily inserted. The width T 1 of the starting end 11Bb of the insertion slot 11B is adapted narrower than the outer diameter of the pipe 20, and is such that the inserted pipe 20 not easily escape.

また、この管支持部１１の底面には、ブラケット部１２の固定孔１２Ｃに嵌合する嵌合突起１１Ｃが突出形成されている。この嵌合突起１１Ｃが固定孔１２Ｃに嵌合することで、管支持部１１のズレが防止される。   Further, a fitting projection 11 </ b> C that fits into the fixing hole 12 </ b> C of the bracket portion 12 is formed on the bottom surface of the tube support portion 11. The fitting protrusion 11C is fitted into the fixing hole 12C, thereby preventing the pipe support portion 11 from being displaced.

なお、第三取付部材１０Ｃでは、４つの支持凹部１１Ａの全てがパイプ２０を支持可能な径寸法に形成されており、一方、第一取付部材１０Ａでは、供給側パイプＺを支持可能な支持凹部と、パイプ２０を支持可能な支持凹部１１Ａとの径寸法の異なる二つの支持凹部が形成されている。   In the third mounting member 10C, all of the four support recesses 11A are formed to have a diameter that can support the pipe 20, while the first mounting member 10A has a support recess that can support the supply side pipe Z. And two support recesses having different diameters from the support recess 11A capable of supporting the pipe 20 are formed.

ブラケット部１２は、金属によって形成され、管支持部１１を載置する載置部１２Ａと、この載置部１２Ａから延在された固定腕１２Ｂとを有している。   The bracket portion 12 is made of metal, and includes a placement portion 12A for placing the tube support portion 11 and a fixed arm 12B extending from the placement portion 12A.

載置部１２Ａは、管支持部１１の底面とほぼ同じ大きさに形成されると共に、ほぼ中央に固定孔１２Ｃが形成されている。そして、この固定孔１２Ｃの周囲には補強リブ１２Ａａが設けられている。   The mounting portion 12A is formed to be approximately the same size as the bottom surface of the tube support portion 11, and a fixing hole 12C is formed at substantially the center. A reinforcing rib 12Aa is provided around the fixed hole 12C.

固定腕１２Ｂは、載置部１２Ａの長手方向一端部が一段高くなるように屈曲して形成されており、載置部１２Ａと直交する方向に延在された固定片１２Ｂａが設けられている。これにより、ブラケット部１２は上面視Ｌ字状となっている。そして、この固定片１２Ｂａの先端には、ボルト貫通孔１３が形成されている。   The fixed arm 12B is formed to bend so that one end in the longitudinal direction of the mounting portion 12A becomes one step higher, and is provided with a fixing piece 12Ba extending in a direction orthogonal to the mounting portion 12A. Thereby, the bracket part 12 is L-shaped when viewed from above. And the bolt through-hole 13 is formed in the front-end | tip of this fixed piece 12Ba.

なお、第一取付部材１０Ａでは、この固定腕１２Ｂが載置部１２Ａの両端部にそれぞれ設けられると共に、この固定腕１２Ｂの端部にボルト貫通孔１３が形成されている。すなわち、第一取付部材１０Ａのブラケット部は上面視直線状となっている。   In the first mounting member 10A, the fixed arm 12B is provided at both ends of the mounting portion 12A, and a bolt through hole 13 is formed at the end of the fixed arm 12B. That is, the bracket portion of the first mounting member 10A is linear when viewed from above.

そして、このボルト貫通孔１３を貫通するボルト１３ａにナット１３ｂが螺合することにより、ブラケット部１２が固定される。なお、この第二取付部材１０Ｂは、図２に示すように、補助パネル７に固定される。また、第一取付部材１０Ａはフロアパネル２に固定される。   And the bracket part 12 is fixed by the nut 13b screwing together in the volt | bolt 13a which penetrates this volt | bolt through-hole 13. As shown in FIG. The second mounting member 10B is fixed to the auxiliary panel 7 as shown in FIG. Further, the first attachment member 10 </ b> A is fixed to the floor panel 2.

ここで、補助パネル７に固定された第三取付部材１０Ｃは、パイプ２０と直交するように配置される（図３参照）。このとき、パイプ２０は、固定腕１２Ｂ側に位置する支持凹部１１Ａから順に挿入されており、パイプ２０が挿入されていない支持凹部１１Ａは、パイプ２０の折返部２１の内側に位置する。   Here, the third attachment member 10C fixed to the auxiliary panel 7 is disposed so as to be orthogonal to the pipe 20 (see FIG. 3). At this time, the pipe 20 is inserted in order from the support recess 11 </ b> A located on the fixed arm 12 </ b> B side, and the support recess 11 </ b> A into which the pipe 20 is not inserted is positioned inside the folded portion 21 of the pipe 20.

すなわち、パイプ２０の折返部２１の内側に管支持部１１が配置されることとなり、この折返部２１は、折り返しの内側に管支持部１１を配置可能な空間２３を有することとなる。   That is, the pipe support portion 11 is disposed inside the folded portion 21 of the pipe 20, and the folded portion 21 has a space 23 in which the tube support portion 11 can be disposed inside the folded portion.

次に、この発明の車両の配管取付構造の作用について説明する。   Next, the operation of the vehicle pipe mounting structure of the present invention will be described.

車両１の走行中、図示しない前輪によって小石等が車両後方に弾かれると、この弾かれた小石等は後方に向かうにつれて次第に上昇しながら飛んでくる。つまり、この小石等はフロアパネル２に下面２ａに向かって車両前方から飛んでくる。   While the vehicle 1 is traveling, if pebbles and the like are repelled rearward by a front wheel (not shown), the pebbles and the like that are repelled fly while gradually rising toward the rear. That is, the pebbles and the like fly to the floor panel 2 from the front of the vehicle toward the lower surface 2a.

ここで、フロアパネル２に取り付けられた管部材であるパイプ２０は折返部２１を有しているが、この折返部２１の先端部の前側近傍には、フロアパネル２から下方に突出する補助パネル７が設けられている。   Here, the pipe 20, which is a pipe member attached to the floor panel 2, has a folded portion 21, and an auxiliary panel that protrudes downward from the floor panel 2 in the vicinity of the front side of the tip portion of the folded portion 21. 7 is provided.

そのため、車両前方から飛んでくる小石等は、パイプ２０の折返部２１の前側近傍のフロアパネル２よりも下方に突出した補助パネル７に当たり、パイプ２０の折返部２１に当たることが防止される。これにより、この折返部２１を簡易な構成で保護することが可能となる。   Therefore, pebbles or the like flying from the front of the vehicle hit the auxiliary panel 7 projecting downward from the floor panel 2 near the front side of the folded portion 21 of the pipe 20 and are prevented from hitting the folded portion 21 of the pipe 20. Thereby, this folding | returning part 21 can be protected with a simple structure.

また、フロアパネル２の下面２ａ側に異物を巻き込んでも、折返部２１の先端部の前側近傍に補助パネル７が位置しているので、折返部２１と補助パネル７との間に異物が巻き込まれにくくなる。そのため、異物によって折返部２１に悪影響が及ぼされることを防止できる。   Even if foreign matter is caught on the lower surface 2 a side of the floor panel 2, the auxiliary panel 7 is located near the front side of the tip of the folded portion 21, so that the foreign matter is caught between the folded portion 21 and the auxiliary panel 7. It becomes difficult. Therefore, it is possible to prevent the folded portion 21 from being adversely affected by the foreign matter.

また、第三取付部材１０Ｃは折返部２１に設けられているので、この第三取付部材１０Ｃによっても折返部２１を保護することができ、さらに折返部２１への悪影響を防止することが可能となる。   Further, since the third attachment member 10C is provided in the folded portion 21, the folded portion 21 can be protected also by the third attachment member 10C, and further, adverse effects on the folded portion 21 can be prevented. Become.

特に、ここでは図２に示すように、第三取付部材１０Ｃを固定するボルト１３ａ、ナット１３ｂが折返部２１の前側に位置すると共に、補助パネル７よりもさらに下方に突出している。そのため、このボルト１３ａ等によっても前方からの小石等が折返部２１に当たることを防止することができる。   In particular, as shown in FIG. 2, a bolt 13 a and a nut 13 b for fixing the third attachment member 10 </ b> C are located on the front side of the folded portion 21 and protrude further downward than the auxiliary panel 7. Therefore, it is possible to prevent the pebbles from the front from hitting the folded portion 21 by the bolts 13a and the like.

そして、第三取付部材１０Ｃは、複数のパイプ２０を支持可能な複数の支持凹部１１Ａが形成された管支持部１１と、この管支持部１１をフロアパネル１２に固定するブラケット部１２とを有し、折返部２１は折り返しの内側に管支持部１１を配置可能な空間２３を有している。   The third mounting member 10C includes a tube support portion 11 in which a plurality of support recesses 11A capable of supporting the plurality of pipes 20 are formed, and a bracket portion 12 that fixes the tube support portion 11 to the floor panel 12. And the folding | returning part 21 has the space 23 which can arrange | position the pipe | tube support part 11 inside folding | returning.

これにより、パイプ２０が複数であっても一つの第三取付部材１０Ｃによって支持することができ、部品点数の増加を抑制することができる。   Thereby, even if there are two or more pipes 20, it can be supported by one third attachment member 10C, and an increase in the number of parts can be suppressed.

また、パイプ２０の本数や外径の大きさ、間隔等によって管支持部１１を取り替えるだけで対応でき、ブラケット部１２はパイプ２０の本数等にかかわらず共用することができる。   Further, it can be dealt with by simply replacing the tube support portion 11 depending on the number of pipes 20, the size of the outer diameter, the interval, etc., and the bracket portion 12 can be shared regardless of the number of pipes 20.

さらに、補助パネル７の一方の側部７ａがトンネル部４に接続され、他方の側部７ｂが一方のサイドシル部５に接続されている。これにより、トンネル部４とサイドシル部５とが連結され、フロアパネル２の剛性を向上させることが可能となる。   Furthermore, one side portion 7 a of the auxiliary panel 7 is connected to the tunnel portion 4, and the other side portion 7 b is connected to one side sill portion 5. Thereby, the tunnel part 4 and the side sill part 5 are connected, and the rigidity of the floor panel 2 can be improved.

そして、上述の実施の形態では、パイプ２０を蛇行させて迂回部Ｙを設けているため、エンジンによって加熱された燃料を迂回部Ｙを流通させて冷却することができる。そのため、熱交換器を使用して燃料の冷却を行うよりも廉価にすることができ、また、フロアパネル２から突出しにくくなり、スペース効率の向上を図ることができる。   And in the above-mentioned embodiment, since the pipe 20 meanders and the bypass part Y is provided, the fuel heated by the engine can be circulated through the bypass part Y and cooled. Therefore, it can be made cheaper than cooling the fuel by using a heat exchanger, and it becomes difficult to protrude from the floor panel 2, so that space efficiency can be improved.
