実公平７−２００２４号公報Japanese Utility Model Publication 7-20024

上記従来の構造では、タンクの一側下角部から突出する支持ブラケットの端部にバンドの下端部を下方に向けて締付けるので、タンクの一側下角部をバンドによって十分に拘束することができず、タンクの固定状態が安定しないおそれがある。   In the above conventional structure, the lower end of the band is tightened downward to the end of the support bracket that protrudes from the lower corner of the tank. Therefore, the lower corner of the tank cannot be sufficiently restrained by the band. The fixed state of the tank may not be stable.

そこで、本発明は、タンクの固定状態を安定させることが可能な車両のタンク固定構造の提供を目的とする。   Accordingly, an object of the present invention is to provide a vehicle tank fixing structure capable of stabilizing the tank fixing state.

上記目的を達成すべく、本発明の第１の態様は、上下方向に延びる縦ブラケット部の下端から横ブラケット部が所定方向の一側に向かって曲折して延びるタンクブラケットの縦ブラケット部を車体側に固定し、横ブラケット部にタンクを載置し、縦ブラケット部の上端部の上連結部から横ブラケット部の一側の端部の下連結部までタンクの外面に沿ってバンドを掛け渡し、バンドの下端部を下連結部に連結して所定の締付け方向に締付けることにより、タンクをバンドによってタンクブラケットに緊締するタンクの固定構造である。   In order to achieve the above object, according to a first aspect of the present invention, a vertical bracket portion of a tank bracket extends from a lower end of a vertical bracket portion extending in a vertical direction by bending a horizontal bracket portion toward one side in a predetermined direction. The tank is placed on the horizontal bracket, and the band is routed along the outer surface of the tank from the upper connection at the upper end of the vertical bracket to the lower connection at one end of the horizontal bracket. This is a tank fixing structure in which the lower end portion of the band is connected to the lower connecting portion and tightened in a predetermined tightening direction, whereby the tank is fastened to the tank bracket by the band.

横ブラケット部の一側の端部は、緊締されるタンクの一側下角部がタンクブラケットから露出するように、タンクの一側下角部よりも所定方向の他側に配置される。下連結部は、タンクの一側下角部よりも他側の下方に配置される。所定の締付け方向は、上記所定方向に沿って他側に向けて設定されている。   One side end of the horizontal bracket portion is disposed on the other side in a predetermined direction from the one side lower corner of the tank so that the one side lower corner of the tank to be tightened is exposed from the tank bracket. The lower connecting portion is disposed below the other side of the lower corner portion on one side of the tank. The predetermined tightening direction is set toward the other side along the predetermined direction.

上記構成では、タンクの一側下角部は、タンクブラケットから露出した状態でバンドによって締付けられる。また、下連結部がタンクの一側下角部よりも他側の下方に配置され、下連結部の締付け方向が所定方向の他側であるので、所定方向に沿った締付け力は、下連結部とタンクの一側下角部との間のバンドの延設方向に沿ったバンドの張り方向の第１の力と、上記バンドの延設方向と直交して斜め上方へ向かう第２の力としてタンクの一側下角部に作用する。このため、タンクの一側下角部を強固に拘束することができ、タンクの固定状態を安定させることができる。   In the above configuration, the lower corner portion on one side of the tank is tightened by the band while being exposed from the tank bracket. In addition, since the lower connecting portion is disposed below the other side of the one side lower corner portion of the tank and the tightening direction of the lower connecting portion is the other side of the predetermined direction, the tightening force along the predetermined direction is The first force in the band tension direction along the extending direction of the band between the lower corner portion of the tank and the tank, and the second force obliquely upward perpendicular to the extending direction of the band Acts on the lower corner of one side. For this reason, the one side lower corner part of a tank can be restrained firmly, and the fixed state of a tank can be stabilized.

本発明の第２の態様は、第１の態様のタンク固定構造であって、横ブラケット部の一側の端部には、バンドガイド面が設けられている。バンドガイド面は、下連結部とタンクの一側下角部との間に配置され、バンドが下連結部からタンクの一側下角部へ直線状に延びるように一側に向かって上方へ傾斜する。   The second aspect of the present invention is the tank fixing structure according to the first aspect, and a band guide surface is provided at one end of the lateral bracket part. The band guide surface is disposed between the lower connection portion and the lower side corner portion of the tank, and is inclined upward toward one side so that the band extends linearly from the lower connection portion to the lower side corner portion of the tank. .

上記構成では、下連結部とタンクの一側下角部との間のバンドの延設方向がバンドガイド面によって規定されるので、タンクの一側下角部を強固に拘束する傾斜角度にバンドガイド面を設定することによって、タンクの一側下角部をより確実に拘束することができる。   In the above configuration, since the band extending direction is defined by the band guide surface between the lower connecting portion and the one side lower corner portion of the tank, the band guide surface is inclined to firmly restrain the one side lower corner portion of the tank. By setting this, one side lower corner of the tank can be more reliably restrained.

本発明によれば、タンクの固定状態を安定させることができる。   According to the present invention, the fixed state of the tank can be stabilized.

In the following description, the front-rear direction is the front-rear direction of the traveling direction of the vehicle, and the left-right direction is the left-right direction when facing the front of the vehicle. In the figure, the arrow FR indicates the front of the vehicle, the arrow IN indicates the inner side in the vehicle width direction, and the arrow UP indicates the upper side of the vehicle. In FIG. 1, only the left side of the vehicle is illustrated, and the right side is not illustrated.

図１に示すように、本実施形態の車両１は、車体フレーム２として、車幅方向両側で前後方向に延びる左右のサイドメンバ３と、車幅方向に延びて左右のサイドメンバ３を連結するクロスメンバ（図示省略）とを備える。サイドメンバ３は、車幅方向内側に開口するＵ状断面であり、前後方向に沿って起立する縦壁部４と、縦壁部４の上端縁から車幅方向内側に曲折する上壁部５と、縦壁部４の下端縁から車幅方向内側に曲折して上壁部５と対向する下壁部６とを一体的に有する。   As shown in FIG. 1, a vehicle 1 according to the present embodiment, as a body frame 2, connects left and right side members 3 that extend in the front-rear direction on both sides in the vehicle width direction, and a left and right side member 3 that extends in the vehicle width direction. A cross member (not shown). The side member 3 has a U-shaped cross section that opens inward in the vehicle width direction, and has a vertical wall portion 4 that stands up in the front-rear direction, and an upper wall portion 5 that bends inward in the vehicle width direction from the upper end edge of the vertical wall portion 4. And a lower wall portion 6 that is bent inward in the vehicle width direction from the lower end edge of the vertical wall portion 4 and is opposed to the upper wall portion 5.

サイドメンバ３の車幅方向外側（左側）の前後方向の所定位置には、燃料タンク（タンク）７が前後１対のタンクブラケット１０及び前後１対のバンド３０によって取付けられる。なお、前後のタンクブラケット１０及び前後のバンド３０は、それぞれ略同じ形状であるため、以下ではその一方について説明し、他方の説明は省略する。   A fuel tank (tank) 7 is attached to a predetermined position in the front-rear direction on the outer side (left side) of the side member 3 in the vehicle width direction by a pair of front and rear tank brackets 10 and a pair of front and rear bands 30. In addition, since the front and rear tank brackets 10 and the front and rear bands 30 have substantially the same shape, one of them will be described below, and the description of the other will be omitted.

燃料タンク７は、タンク上面部７ａとタンク底面部７ｂとタンク前面部７ｃとタンク後面部７ｄとタンク内側面部７ｅとタンク外側面部７ｆとが一体形成された略矩形箱体状である。タンク外側面部７ｆの下端とタンク底面部７ｂの車幅方向外端との間は湾曲状に曲折し、この曲折部分が燃料タンク７の外側下角部（一側下角部）８となる。   The fuel tank 7 has a substantially rectangular box shape in which a tank upper surface portion 7a, a tank bottom surface portion 7b, a tank front surface portion 7c, a tank rear surface portion 7d, a tank inner surface portion 7e, and a tank outer surface portion 7f are integrally formed. Between the lower end of the tank outer surface portion 7f and the outer end of the tank bottom surface portion 7b in the vehicle width direction is bent in a curved shape, and this bent portion becomes the outer lower corner portion (one side lower corner portion) 8 of the fuel tank 7.

タンクブラケット１０は、金属製長尺板材をＬ状に曲折した部材であり、直線状に延びる縦ブラケット部１１と、縦ブラケット部１１の下端から略直角に曲折して直線状に延びる横ブラケット部１２とを一体的に有する。なお、本実施形態のタンクブラケット１０は、そのほぼ全域が矩形閉断面状であるが、タンクブラケット１０の断面形状はこれに限定されず任意である。   The tank bracket 10 is a member obtained by bending a metal long plate material into an L shape, and a vertical bracket portion 11 extending linearly and a horizontal bracket portion extending linearly by bending substantially perpendicularly from the lower end of the vertical bracket portion 11. 12 integrally. The tank bracket 10 of the present embodiment has a rectangular closed cross section over almost the entire area, but the cross section of the tank bracket 10 is not limited to this and is arbitrary.

縦ブラケット部１１は、上下方向に起立した姿勢でサイドメンバ３の縦壁部４の外側面に結合される。縦ブラケット部１１が縦壁部４に結合されることにより、タンクブラケット１０がサイドメンバ３に固定される。係るブラケット取付状態で、横ブラケット部１２は縦ブラケット部１１の下端から車幅方向外側（所定方向の一側）に向かって曲折して延びる。   The vertical bracket portion 11 is coupled to the outer surface of the vertical wall portion 4 of the side member 3 in an upright posture. The tank bracket 10 is fixed to the side member 3 by connecting the vertical bracket portion 11 to the vertical wall portion 4. In this bracket mounting state, the horizontal bracket portion 12 extends from the lower end of the vertical bracket portion 11 by bending toward the outside in the vehicle width direction (one side in a predetermined direction).

横ブラケット部１２に燃料タンク７を載置し、縦ブラケット部１１の上端部の上連結部１３から横ブラケット部１２の車幅方向外側の端部の下連結部１４まで燃料タンク７の外面（タンク上面部７ａ及びタンク外側面部７ｆの外面）に沿って帯状のバンド３０を掛け渡し、バンド３０の下端部を下連結部１４に連結して所定の締付け方向（本実施形態では後述するように車幅方向内側）に締付けることにより、燃料タンク７がバンド３０によってタンクブラケット１０に緊締される。   The fuel tank 7 is placed on the horizontal bracket portion 12, and the outer surface of the fuel tank 7 from the upper connection portion 13 of the upper end portion of the vertical bracket portion 11 to the lower connection portion 14 of the lateral bracket portion 12 outer end in the vehicle width direction ( A band-shaped band 30 is stretched along the tank upper surface portion 7a and the outer surface of the tank outer surface portion 7f, and the lower end portion of the band 30 is connected to the lower connecting portion 14 to be fixed in a predetermined tightening direction (as will be described later in this embodiment). By tightening inward in the vehicle width direction, the fuel tank 7 is fastened to the tank bracket 10 by the band 30.

図２に示すように、バンド３０の上端部には、板状のフック３１が固定され、タンクブラケット１０の上連結部１３には、フック３１が上方から挿入されて係合する係合凹部１５が形成されている。フック３１を係合凹部１５に係合することにより、バンド３０の上端部がタンクブラケット１０の上連結部１３に着脱可能に連結される。   As shown in FIG. 2, a plate-like hook 31 is fixed to the upper end portion of the band 30, and the engagement recess 15 into which the hook 31 is inserted and engaged with the upper connecting portion 13 of the tank bracket 10. Is formed. By engaging the hook 31 with the engagement recess 15, the upper end portion of the band 30 is detachably connected to the upper connection portion 13 of the tank bracket 10.

図３に示すように、バンド３０の下端部には環状の連結部材装着部３２が形成され、連結部材装着部３２に連結部材３３が保持される。連結部材３３は、円筒状の軸挿通部３４と、軸挿通部３４の外周から相反する方向へ突出する１対の軸状突起３５と、各軸状突起３５の先端に固定されて軸状突起３５よりも大きい外径を有する円板状の１対の係止板３６とを一体的に有する。連結部材装着部３２は、バンド３０を下端部で折り返し、その先端部をバンド３０の中間部に溶着等により固定することによって形成される。連結部材装着部３２の末端の折り返し部分には、軸挿通部３４を露出させるための開口３７が形成されている。連結部材３３は、軸状突起３５の軸方向がバンド３０の幅方向に沿った状態で連結部材装着部３２内に挿入される。係る装着状態で、軸挿通部３４の両端面が開口３７から露出し、１対の軸状突起３５に連結部材装着部３２が掛け渡され、１対の係止板３６がバンド３０の幅方向両側から外側に突出する。装着状態では、係止板３６によってバンド３０の幅方向に沿った連結部材３３の移動が規制され、連結部材３３が連結部材装着部３２に保持される。   As shown in FIG. 3, an annular connecting member mounting portion 32 is formed at the lower end portion of the band 30, and the connecting member 33 is held by the connecting member mounting portion 32. The connecting member 33 includes a cylindrical shaft insertion portion 34, a pair of shaft projections 35 projecting in opposite directions from the outer periphery of the shaft insertion portion 34, and shaft projections fixed to the tips of the shaft projections 35. A pair of disk-shaped locking plates 36 having an outer diameter larger than 35 are integrally provided. The connecting member mounting portion 32 is formed by folding the band 30 at the lower end portion and fixing the tip end portion to the intermediate portion of the band 30 by welding or the like. An opening 37 for exposing the shaft insertion portion 34 is formed in the folded portion at the end of the connecting member mounting portion 32. The connecting member 33 is inserted into the connecting member mounting portion 32 in a state where the axial direction of the axial protrusion 35 is along the width direction of the band 30. In such a mounted state, both end surfaces of the shaft insertion portion 34 are exposed from the opening 37, the connecting member mounting portion 32 is stretched over the pair of shaft-like protrusions 35, and the pair of locking plates 36 are arranged in the width direction of the band 30. Projects outward from both sides. In the mounted state, the movement of the connecting member 33 along the width direction of the band 30 is restricted by the locking plate 36, and the connecting member 33 is held by the connecting member mounting portion 32.

図４及び図５に示すように、タンクブラケット１０の下連結部１４は、連結部材締結ブラケット１６とボルト軸１７と２つのナット１８とによって構成される。連結部材締結ブラケット１６は、車幅方向と略直交する締結板部１９と、締結板部１９の前端縁及び後端縁から曲折し車幅方向内側に向かって斜め上方へ延びる前後１対の固定板部２０とを一体的に有し、金属板を曲折することによって形成される。前後の固定板部２０が横ブラケット部１２の前後の側面部２１に溶着されることにより、締結板部１９が横ブラケット部１２の下方に位置した状態で、連結部材締結ブラケット１６が横ブラケット部１２に固定される。ボルト軸１７は、連結部材３３の軸挿通部３４の内径部よりも僅かに小さい外径を有し、締結板部１９に固着されて車幅方向に沿って延び、締結板部１９から車幅方向外側へ突出する。ナット１８は車幅方向外側からボルト軸１７に螺合する。   As shown in FIGS. 4 and 5, the lower connecting portion 14 of the tank bracket 10 includes a connecting member fastening bracket 16, a bolt shaft 17, and two nuts 18. The connecting member fastening bracket 16 has a fastening plate portion 19 that is substantially orthogonal to the vehicle width direction, and a pair of front and rear fixing members that bend from the front and rear edges of the fastening plate portion 19 and extend obliquely upward inward in the vehicle width direction. It has the board part 20 integrally and is formed by bending a metal plate. The front and rear fixing plate portions 20 are welded to the front and rear side surface portions 21 of the lateral bracket portion 12, so that the connecting member fastening bracket 16 is disposed in the lateral bracket portion in a state where the fastening plate portion 19 is positioned below the lateral bracket portion 12. 12 is fixed. The bolt shaft 17 has an outer diameter slightly smaller than the inner diameter portion of the shaft insertion portion 34 of the connecting member 33, is fixed to the fastening plate portion 19 and extends along the vehicle width direction, and extends from the fastening plate portion 19 to the vehicle width. Projects outward in the direction. The nut 18 is screwed onto the bolt shaft 17 from the outside in the vehicle width direction.

バンド３０の下端部（連結部材装着部３２）に保持された連結部材３３の軸挿通部３４の内径部にボルト軸１７を車幅方向外側から挿通し、ナット１８を車幅方向外側からボルト軸１７に螺合し、螺合したナット１８を車幅方向内側へ締め込むことによって、バンド３０の下端部は、下連結部１４に連結されるとともに、車幅方向内側に締付けられる。すなわち、下連結部１４におけるバンド３０の下端部の締付け方向は、車幅方向に沿って車幅方向内側に向けて設定されている。なお、ナット１８を二重に締結するのは、ナット１８の緩み防止のためである。   The bolt shaft 17 is inserted from the outer side in the vehicle width direction into the inner diameter portion of the shaft insertion portion 34 of the connecting member 33 held by the lower end portion (the connecting member mounting portion 32) of the band 30, and the nut 18 is inserted from the outer side in the vehicle width direction to the bolt shaft. The lower end portion of the band 30 is connected to the lower connecting portion 14 and is tightened to the inner side in the vehicle width direction by tightening the nut 18 screwed into the screw 17 and the screwed nut 18 to the inner side in the vehicle width direction. That is, the tightening direction of the lower end portion of the band 30 in the lower connecting portion 14 is set inward in the vehicle width direction along the vehicle width direction. The nut 18 is double-fastened to prevent the nut 18 from loosening.

図４〜図６に示すように、横ブラケット部１２の車幅方向外側の先端部の下面は、車幅方向外側に向かって斜め上方へ傾斜するバンドガイド面２２を構成する。バンドガイド面２２は、タンクブラケット１０の下連結部１４と燃料タンク７の外側下角部８との間に配置され、バンド３０は、バンドガイド面２２と面接触することによって、下連結部１４の上方近傍から燃料タンク７の外側下角部８へ直線状に延びる。   As shown in FIGS. 4 to 6, the lower surface of the distal end portion on the outer side in the vehicle width direction of the lateral bracket portion 12 constitutes a band guide surface 22 that is inclined obliquely upward toward the outer side in the vehicle width direction. The band guide surface 22 is disposed between the lower connection portion 14 of the tank bracket 10 and the outer lower corner portion 8 of the fuel tank 7, and the band 30 is in surface contact with the band guide surface 22, thereby It extends linearly from the upper vicinity to the outer lower corner 8 of the fuel tank 7.

横ブラケット部１２の車幅方向外側の先端（バンドガイド面２２の上端）は、燃料タンク７の外側下角部８よりも車幅方向内側に配置される。すなわち、横ブラケット部１２の車幅方向外側の端部は、緊締される燃料タンク７の外側下角部８がタンクブラケット１０から露出するように、燃料タンク７の外側下角部８よりも車幅方向内側に配置され、下連結部１４は、燃料タンク７の外側下角部８よりも車幅方向内側の下方に配置される。   The front end of the lateral bracket portion 12 on the outer side in the vehicle width direction (the upper end of the band guide surface 22) is disposed on the inner side in the vehicle width direction with respect to the outer lower corner portion 8 of the fuel tank 7. That is, the end of the lateral bracket portion 12 on the outer side in the vehicle width direction is wider than the outer lower corner portion 8 of the fuel tank 7 so that the outer lower corner portion 8 of the fuel tank 7 to be tightened is exposed from the tank bracket 10. The lower connecting portion 14 is disposed on the inner side, and is disposed below the outer lower corner portion 8 of the fuel tank 7 on the inner side in the vehicle width direction.

本実施形態によれば、燃料タンク７の外側下角部８は、タンクブラケット１０から露出した状態でバンド３０によって締付けられる。また、下連結部１４が燃料タンク７の外側下角部８よりも車幅方向内側の下方に配置され、下連結部１４の締付け方向が車幅方向内側であるので、図６に示すように、車幅方向に沿った締付け力Ｆｔは、下連結部１４と燃料タンク７の外側下角部８との間のバンド３０の延設方向に沿った第１の力Ｆ１と、バンド３０の延設方向と直交して斜め上方へ向かう第２の力Ｆ２として、燃料タンク７の外側下角部８に作用する。このため、燃料タンク７の外側下角部８をバンド３０によって強固に拘束することができ、燃料タンク７の固定状態を安定させることができる。   According to the present embodiment, the outer lower corner portion 8 of the fuel tank 7 is tightened by the band 30 while being exposed from the tank bracket 10. Further, since the lower connecting portion 14 is disposed below the outer lower corner portion 8 of the fuel tank 7 on the inner side in the vehicle width direction, and the tightening direction of the lower connecting portion 14 is the inner side in the vehicle width direction, as shown in FIG. The tightening force Ft along the vehicle width direction includes the first force F1 along the extending direction of the band 30 between the lower connecting portion 14 and the outer lower corner portion 8 of the fuel tank 7, and the extending direction of the band 30. Acting on the outer lower corner portion 8 of the fuel tank 7 as a second force F2 that is orthogonal to and obliquely upward. For this reason, the outer lower corner 8 of the fuel tank 7 can be firmly restrained by the band 30, and the fixed state of the fuel tank 7 can be stabilized.

また、下連結部１４と燃料タンク７の外側下角部８との間のバンド３０の延設方向がバンドガイド面２２によって一律に規定されるので、燃料タンク７の外側下角部８を強固に拘束する傾斜角度にバンドガイド面２２を設定することによって、燃料タンク７の外側下角部８をより確実に拘束することができる。   Further, since the extending direction of the band 30 between the lower connecting portion 14 and the outer lower corner portion 8 of the fuel tank 7 is uniformly defined by the band guide surface 22, the outer lower corner portion 8 of the fuel tank 7 is firmly restrained. By setting the band guide surface 22 at an inclined angle, the outer lower corner portion 8 of the fuel tank 7 can be more reliably restrained.

また、ボルト軸１７に対してナット１８を車幅方向外側から締付けるので、車体側に固定されたタンクブラケット１０に燃料タンク７を固定する際の作業性が良い。   Further, since the nut 18 is fastened to the bolt shaft 17 from the outside in the vehicle width direction, the workability when the fuel tank 7 is fixed to the tank bracket 10 fixed to the vehicle body side is good.

以上、本発明者によってなされた発明を適用した実施形態について説明したが、この実施形態による本発明の開示の一部をなす論述及び図面により本発明は限定されることはない。すなわち、この実施形態に基づいて当業者等によりなされる他の実施形態、実施例及び運用技術等は全て本発明の範疇に含まれることは勿論である。   As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the discussion and the drawings that form part of the disclosure of the present invention according to this embodiment.
