Description

本発明は、車体側に固定されるタンクの保護構造に関する。   The present invention relates to a protection structure for a tank fixed to a vehicle body.

特許文献１には、アッパメンバとロアメンバとの接合部のフランジ部に、フランジ部を被包するプロテクタを装着した構造が記載されている。プロテクタは、サブフレームの前方に配設された容積部材に対向して、フランジ部に沿って装着される。   Patent Literature 1 describes a structure in which a protector for enclosing the flange portion is mounted on a flange portion at a joint between the upper member and the lower member. The protector is mounted along the flange, facing the volume member disposed in front of the subframe.

特開平８−１８８１７３号公報JP-A-8-188173

特許文献１の構造では、フランジ部がプロテクタに被包されているので、フランジ部が容積部材に当接せず、容積部材の損傷を抑制することができる。   In the structure of Patent Literature 1, since the flange portion is covered by the protector, the flange portion does not come into contact with the volume member, so that damage to the volume member can be suppressed.

しかし、車両の衝突時のようにフランジ部（板状部）から容積部材（タンク）へ入力する荷重が過大となった場合、プロテクタの離脱や破損によりタンクが損傷してしまうおそれがある。   However, when the load input from the flange portion (plate-shaped portion) to the volume member (tank) becomes excessive, such as at the time of a vehicle collision, the tank may be damaged due to detachment or breakage of the protector.

また、フランジ部の形状に合わせた成形型によってプロテクタを成形する必要があるため、形状の異なるフランジ部（板状部）への対応が煩雑である。   Further, since it is necessary to form the protector with a molding die adapted to the shape of the flange portion, it is complicated to deal with flange portions (plate-shaped portions) having different shapes.

そこで、本発明は、タンクの損傷を簡易に且つ確実に抑制することが可能なタンクの保護構造の提供を目的とする。   Therefore, an object of the present invention is to provide a tank protection structure capable of easily and reliably suppressing damage to a tank.

上記目的を達成すべく、本発明の第１の態様は、車体側に固定されるタンクの保護構造であって、金属製の板状部と、円形断面の棒体状又は円管状の金属製の線状体と、を備える。   In order to achieve the above object, a first aspect of the present invention is a protection structure for a tank fixed to a vehicle body, comprising a metal plate-like portion, a rod-shaped or tubular metal having a circular cross section. And a linear body.

板状部は、表裏の板面の端縁に区画される板厚方向の端面が、隣接して角部を形成する第１端面及び第２端面を含み、少なくとも第１端面がタンクの表面と対向する姿勢で車体側に固定される。線状体は、第１端面の面上で端縁に沿って線状に延びる第１線状部と、角部に沿って湾曲する湾曲部と、第２端面の面上で端縁に沿って線状に延びる第２線状部とを一体的に有し、板状部に溶着される。   The plate-like portion has a first end surface and a second end surface which are adjacent to each other and form a corner, and the end surface in the thickness direction defined by the edges of the front and rear plate surfaces, and at least the first end surface is in contact with the surface of the tank. It is fixed to the vehicle body in the facing posture. The linear body includes a first linear portion extending linearly along the edge on the surface of the first end surface, a curved portion curved along the corner, and an edge along the edge of the second end surface. And a second linear portion extending linearly and is welded to the plate-like portion.

本発明の第２の態様は、車体側に固定されるタンクの保護構造であって、互いに離間して相対向する２枚の金属製の板状部と、円形断面の棒体状又は円管状の金属製の線状体と、を備える。   A second aspect of the present invention is a protection structure for a tank fixed to a vehicle body side, comprising two metal plate-shaped portions spaced apart from each other and facing each other, and a rod-shaped or circular tube having a circular cross section. And a metal linear body.

２枚の板状部の各々は、表裏の板面の端縁に区画される板厚方向の端面が、隣接して角部を形成する第１端面及び第２端面を含み、少なくとも第１端面がタンクの表面と対向する姿勢で車体側に固定される。線状体は、２枚の板状部の第１端面の各々の面上で端縁に沿って線状に延びる２本の第１線状部と、２枚の板状部の角部の各々の近傍で２本の第１線状部から互いに向かい合う方向へ湾曲し、直接又は中間線状部を介して連続する２箇所の湾曲部とを一体的に有し、２枚の板状部に溶着される。   In each of the two plate-like portions, an end surface in the thickness direction defined by an edge of the front and back plate surfaces includes a first end surface and a second end surface forming adjacent corners, and at least the first end surface. Is fixed to the vehicle body in a posture facing the surface of the tank. The linear body includes two first linear portions linearly extending along an edge on each of the first end surfaces of the two plate portions, and a corner portion of the two plate portions. In the vicinity of each of the two first linear portions, the first linear portions are curved in a direction facing each other, and integrally have two curved portions that are continuous directly or through an intermediate linear portion, and are two plate-shaped portions. Welded to.

上記構成では、板状部の第１端面及び角部とタンクの表面との間に線状体の円弧状の外周面が介在するので、板状部の角部や第１端面の端縁（エッジ）がタンクの表面に当接せず、タンクの損傷を抑制することができる。   In the above configuration, since the arc-shaped outer peripheral surface of the linear body is interposed between the first end face and the corner of the plate-shaped part and the surface of the tank, the corner of the plate-shaped part and the edge of the first end face ( The edge) does not contact the surface of the tank, so that damage to the tank can be suppressed.

また、線状体が板状部に溶着されているので、車両の衝突時のように板状部からタンクへ入力する荷重が過大となった場合であっても、線状体の離脱や破損が生じ難く、タンクの損傷を線状体によって確実に抑制することができる。   In addition, since the linear body is welded to the plate-shaped portion, even if the load input from the plate-shaped portion to the tank becomes excessive as in the case of a vehicle collision, the linear body is detached or damaged. Is less likely to occur, and damage to the tank can be reliably suppressed by the linear body.

さらに、金属製の棒体や円管を板状部の形状に合わせて曲折することにより線状体を形成することができるので、形状の異なる板状部への対応が容易であり、タンクの損傷を簡易に抑制することができる。   Furthermore, since a linear body can be formed by bending a metal rod or a circular tube in accordance with the shape of the plate-shaped portion, it is easy to handle a plate-shaped portion having a different shape, and the tank can be easily formed. Damage can be easily suppressed.

本発明の第３の態様は、第１又は第２の態様のタンクの保護構造であって、線状部材の外径は、第１端面における板状部の板厚以上に設定される。   A third aspect of the present invention is the tank protection structure according to the first or second aspect, wherein an outer diameter of the linear member is set to be equal to or greater than a thickness of the plate-shaped portion at the first end face.

上記構成では、板状部の角部や第１端面の端縁とタンクの表面との当接をより確実に防止することができる。   In the above configuration, it is possible to more reliably prevent the corner of the plate-shaped portion or the edge of the first end face from contacting the tank surface.

本発明によれば、タンクの損傷を簡易に且つ確実に抑制することができる。   ADVANTAGE OF THE INVENTION According to this invention, damage to a tank can be suppressed easily and reliably.

The inner surface 2a of the tank 2 in the vehicle width direction (tank inner side surface) is separated from the outer surface 1a of the side member 1 in the vehicle width direction (side member outer surface) 1a outward in the vehicle width direction.

サイドメンバ外側面１ａとタンク内側面２ａとの間には、所定の部品又は部材（例えば、排気管のサイレンサ）を支持するためのブラケット４が配置される。ブラケット４は、ブラケット本体５とリブ（板状部）６とを有する。ブラケット本体５は、Ｌ形状に曲折する金属板であり、サイドメンバ外側面１ａにボルト２７によって締結固定されるブラケット縦板部７と、ブラケット縦板部７の下端縁から車幅方向内側に曲折して延びるブラケット横板部８とを一体的に有する。ブラケット縦板部７は、車幅方向と略直交し、ブラケット横板部８は、鉛直方向と略直交する。   A bracket 4 for supporting a predetermined component or member (for example, a silencer of an exhaust pipe) is disposed between the side member outer surface 1a and the tank inner surface 2a. The bracket 4 has a bracket body 5 and a rib (plate-like portion) 6. The bracket main body 5 is a metal plate that is bent into an L shape, and is bent inward in the vehicle width direction from the lower end edge of the bracket vertical plate portion 7 that is fastened and fixed to the side member outer surface 1a with a bolt 27. And a bracket horizontal plate portion 8 extending as a unit. The bracket vertical plate portion 7 is substantially orthogonal to the vehicle width direction, and the bracket horizontal plate portion 8 is approximately orthogonal to the vertical direction.

図１〜図５に示すように、リブ６は、板面がＬ形状の金属板であり、リブ縦板部９とリブ横板部１０とを一体的に有し、溶接２５によってブラケット本体５に固定される。リブ縦板部９は、ブラケット縦板部７の車幅方向外側の表面（ブラケット縦板外側面）７ａから車幅方向外側へ起立して上下方向に延びる。リブ横板部１０は、リブ縦板部９の下端から車幅方向内側に曲折し、ブラケット横板部８の下面（ブラケット横板下面）８ａから下方へ起立して車幅方向に延びる。リブ６の板厚Ｄ１は、リブ縦板部９及びリブ横板部１０の全域に亘って略同じであり、リブ縦板部９及びリブ横板部１０は、前後方向と略直交する。   As shown in FIGS. 1 to 5, the rib 6 is a metal plate having an L-shaped plate surface, and integrally has a rib vertical plate portion 9 and a rib horizontal plate portion 10. Fixed to The rib vertical plate portion 9 stands upright from the outer surface (a bracket vertical plate outer surface) 7a of the bracket vertical plate portion 7 in the vehicle width direction and extends vertically in the vehicle width direction. The rib horizontal plate portion 10 is bent inward from the lower end of the rib vertical plate portion 9 in the vehicle width direction, rises downward from the lower surface (the lower surface of the bracket horizontal plate) 8a of the bracket horizontal plate portion 8, and extends in the vehicle width direction. The plate thickness D1 of the rib 6 is substantially the same over the entire area of the rib vertical plate portion 9 and the rib horizontal plate portion 10, and the rib vertical plate portion 9 and the rib horizontal plate portion 10 are substantially orthogonal to the front-rear direction.

リブ６の板厚方向の端面１２は、リブ６の前面（表裏の板面の一方）６ａ及び後面（表裏の板面の他方）６ｂの端縁（エッジ）１１によって区画され（図５参照）、係る端面１２には、リブ上端面（第２端面）１３と、リブ外端面（第１端面）１４と、リブ下端面（第２端面）１５と、リブ内端面１６とが含まれる。リブ上端面１３はリブ縦板部９の上端面であり、リブ外端面１４はリブ縦板部９の車幅方向外側の端面であり、リブ下端面１５はリブ横板部１０の下端面であり、リブ内端面１６はリブ横板部１０の車幅方向内側の端面である。リブ上端面１３とリブ外端面１４とは、リブ６（リブ縦板部９）の車幅方向外側の上端隅の角部１７を形成し、リブ外端面１４とリブ下端面１５とは、リブ６（リブ縦板部９及びリブ横板部１０）の車幅方向外側の下端隅の角部１８を形成する。角部１７，１８は円弧状に湾曲し、角部１７は角部１８よりも鋭角である。リブ外端面１４及び角部１７，１８は、タンク２の車幅方向内側の表面２ａに車幅方向内側から対向する。   An end face 12 in the thickness direction of the rib 6 is defined by a front surface (one of the front and back plate surfaces) 6a and an edge (edge) 11 of a rear surface (the other of the front and back plate surfaces) 6b of the rib 6 (see FIG. 5). The end face 12 includes a rib upper end face (second end face) 13, a rib outer end face (first end face) 14, a rib lower end face (second end face) 15, and a rib inner end face 16. The rib upper end surface 13 is the upper end surface of the rib vertical plate portion 9, the rib outer end surface 14 is the end surface of the rib vertical plate portion 9 on the outer side in the vehicle width direction, and the rib lower end surface 15 is the lower end surface of the rib horizontal plate portion 10. The rib inner end surface 16 is an end surface of the rib horizontal plate portion 10 on the inner side in the vehicle width direction. The rib upper end face 13 and the rib outer end face 14 form a corner 17 at the upper end corner of the rib 6 (rib vertical plate portion 9) on the outer side in the vehicle width direction, and the rib outer end face 14 and the rib lower end face 15 6 (the rib vertical plate portion 9 and the rib horizontal plate portion 10) are formed with corner portions 18 at the lower end corners on the outer side in the vehicle width direction. The corners 17 and 18 are curved in an arc shape, and the corner 17 is more acute than the corner 18. The rib outer end face 14 and the corner portions 17 and 18 face the inner surface 2 a of the tank 2 in the vehicle width direction from the inside in the vehicle width direction.

リブ６の板厚方向の端面１２には、金属製の１本の丸棒（線状体）２０が溶接２６によって固定される。丸棒２０は、Ｊ形状に曲折された円形断面の棒体であり、上線状部（第２線状部）２１と、縦線状部（第１線状部）２２と、下線状部（第２線状部）２３と、上下の湾曲部２４，２５とを一体的に有する。上線状部２１は、リブ上端面１３の面上で端縁１１に沿って車幅方向に延びる。縦線状部２２は、リブ外端面１４の面上で端縁１１に沿って上下方向に延びる。下線状部２３は、リブ下端面１５の面上で端縁１１に沿って車幅方向に延びる。上側の湾曲部２４は、上線状部２１の車幅方向外側の外端と縦線状部２２の上端との間で、上側の角部１７に沿って湾曲する。また、本実施形態では、丸棒２０の外径Ｄ２は、リブ６の板厚Ｄ１以上に設定されている（図５参照）。   One metal round bar (linear body) 20 is fixed to the end surface 12 of the rib 6 in the plate thickness direction by welding 26. The round bar 20 is a rod body having a circular cross section bent into a J shape, and includes an upper linear portion (second linear portion) 21, a vertical linear portion (first linear portion) 22, and an underlined portion ( (A second linear portion) 23 and upper and lower curved portions 24 and 25. The upper linear portion 21 extends in the vehicle width direction along the edge 11 on the surface of the rib upper end surface 13. The vertical linear portion 22 extends vertically along the edge 11 on the surface of the rib outer end surface 14. The underlined portion 23 extends in the vehicle width direction along the edge 11 on the surface of the rib lower end surface 15. The upper curved portion 24 is curved along the upper corner portion 17 between the outer end of the upper linear portion 21 in the vehicle width direction and the upper end of the vertical linear portion 22. In the present embodiment, the outer diameter D2 of the round bar 20 is set to be equal to or greater than the thickness D1 of the rib 6 (see FIG. 5).

なお、丸棒２０に代えて、金属製の円管（パイプ）を線状体として用いてもよい。   Instead of the round bar 20, a metal circular pipe (pipe) may be used as the linear body.

本実施形態によれば、リブ外端面１４及び角部１７，１８とタンク２の表面２ａとの間に丸棒２０の円弧状の外周面が介在するので、タンク２とリブ６とが近付いた場合であっても、リブ６の角部１７，１８や端縁１１がタンク２の表面２ａに当接せず、タンク２の損傷を抑制することができる。   According to the present embodiment, since the arc-shaped outer peripheral surface of the round bar 20 is interposed between the rib outer end surface 14 and the corners 17 and 18 and the surface 2a of the tank 2, the tank 2 and the rib 6 come closer. Even in this case, the corners 17 and 18 and the edge 11 of the rib 6 do not contact the surface 2 a of the tank 2, so that damage to the tank 2 can be suppressed.

また、丸棒２０がリブ６に溶着されているので、車両の衝突時のようにリブ６からタンク２へ入力する荷重が過大となった場合であっても、丸棒２０の離脱や破損が生じ難く、タンク２の損傷を丸棒２０によって確実に抑制することができる。   Further, since the round bar 20 is welded to the rib 6, even if the load input from the rib 6 to the tank 2 becomes excessive, such as at the time of a vehicle collision, the round bar 20 may not be detached or damaged. It is unlikely to occur, and damage to the tank 2 can be reliably suppressed by the round bar 20.

また、金属製の棒体や円管をリブ６の形状に合わせて曲折することにより線状体を形成することができるので、形状の異なるリブ６への対応が容易であり、タンク２の損傷を簡易に抑制することができる。   Further, since a linear body can be formed by bending a metal rod or a circular tube in accordance with the shape of the rib 6, it is easy to cope with the rib 6 having a different shape, and the tank 2 is damaged. Can be easily suppressed.

さらに、丸棒２０の外径Ｄ２をリブ６の板厚Ｄ１以上としているので、リブ６の角部１７，１８や端縁１１とタンク２の表面２ａとの当接をより確実に防止することができる。   Further, since the outer diameter D2 of the round bar 20 is equal to or greater than the plate thickness D1 of the rib 6, it is possible to more reliably prevent the corners 17, 18 and the edge 11 of the rib 6 from contacting the surface 2a of the tank 2. Can be.
