Description

本発明は、車両にワイヤハーネスを固定するためのワイヤハーネス固定構造に関する。   The present invention relates to a wire harness fixing structure for fixing a wire harness to a vehicle.

車両にワイヤハーネスを固定するためのワイヤハーネス固定構造が知られている。例えば特許文献１には車両にワイヤハーネスを固定するためのワイヤハーネス固定構造が記載されている。   A wire harness fixing structure for fixing a wire harness to a vehicle is known. For example, Patent Literature 1 describes a wire harness fixing structure for fixing a wire harness to a vehicle.

特許文献１に記載のワイヤハーネス固定構造は、車体の板状部材に取り付けられるクランプと、ワイヤハーネスを保持するホルダーとから構成される。そして、クランプは、ばね弾性を有する平板状金属板から形成され、挟持部とアンカー装着台を有する。挟持部は略Ｕ字形に屈曲して板状部材を挟み付けするように形成される。アンカー装着台は略Π形に屈曲して板状部材に当接するように形成される。ホルダーには本体部とアンカー部とが形成され、本体部でワイヤハーネスを保持した状態で、アンカー部をアンカー装着台に結合することによってワイヤハーネスを固定する。   The wire harness fixing structure described in Patent Literature 1 includes a clamp attached to a plate-like member of a vehicle body and a holder that holds the wire harness. And a clamp is formed from the flat metal plate which has spring elasticity, and has a clamping part and an anchor mounting base. The clamping part is formed so as to be bent in a substantially U shape and sandwich the plate member. The anchor mounting base is formed so as to be bent in a substantially bowl shape and abut on the plate member. The holder is formed with a main body portion and an anchor portion, and the wire harness is fixed by coupling the anchor portion to the anchor mounting base in a state where the wire harness is held by the main body portion.

ところで、特許文献１に記載のワイヤハーネス固定構造のように、ボルト止めができない部材に対しては、ブラケットによって挟む形式での固定が考えられるが、例えば棒状の固定部材にブラケットを固定する場合に、回り止めが不十分なため、振動などの要因によりブラケットが固定部材に対して回転してその位置がずれる回転ずれを生じる懸念がある。また、棒状の固定部材をブラケットの平面と平面とで挟み込む構造では、その平面内の意図しない突出点で接触し、回転時に軸となる点に対する回り止めとなる点の位置が一定にならないおそれがある。このため、回転軸となる点と回り止めとなる点の間の距離が個々に大きくばらつくことがあり、この距離が短い場合に回転入力に対する抵抗する力が小さくなり、回転ずれを生じるおそれがある。   By the way, as in the wire harness fixing structure described in Patent Document 1, it is conceivable to fix a member that cannot be bolted with a bracket. For example, when the bracket is fixed to a rod-shaped fixing member. Since the rotation prevention is insufficient, there is a concern that the bracket may be rotated with respect to the fixed member due to vibration or the like and the position may be shifted. In addition, in the structure in which the rod-shaped fixing member is sandwiched between the planes of the brackets, there is a possibility that the position of the point that becomes a detent relative to the point that becomes the axis at the time of rotation may not be constant due to contact at an unintended protruding point in the plane is there. For this reason, the distance between the point serving as the rotation axis and the point serving as the rotation stopper may vary greatly, and when this distance is short, the resistance force against the rotation input is reduced, and there is a risk of causing rotational deviation. .

また、形状の異なる複数のスタビライザに対応する場合に、それぞれの種類のスタビライザの形状に合わせて、ブラケットの種類も増やすこととなる問題もある。このように従来のワイヤハーネス固定構造には、棒状部に対するワイヤハーネスを固定するためのブラケットの回転ずれを効果的に抑制しつつ、形状の異なる複数のスタビライザに対応可能とする観点から改善の余地があった。   Moreover, when dealing with a plurality of stabilizers having different shapes, there is a problem that the types of brackets are increased in accordance with the shapes of the respective types of stabilizers. As described above, the conventional wire harness fixing structure has room for improvement from the viewpoint of being able to cope with a plurality of stabilizers having different shapes while effectively suppressing rotational deviation of the bracket for fixing the wire harness to the rod-shaped portion. was there.

本発明の目的は、スタビライザの棒状部に対するワイヤハーネスを固定するためのブラケットの回転ずれを効果的に抑制しうるワイヤハーネス固定構造の技術を提供することにある。   The objective of this invention is providing the technique of the wire harness fixing structure which can suppress effectively the rotation shift of the bracket for fixing the wire harness with respect to the rod-shaped part of a stabilizer.

上記課題を解決するために、本発明のある態様のワイヤハーネス固定構造は、車両に設けられるスタビライザの棒状の部分である棒状部と、棒状部にワイヤハーネスを固定するためのブラケットと、を備える。棒状部の外周面には、当該棒状部の中心軸を挟むように第１平面部と第２平面部とが設けられ、ブラケットは第１当接部材と第２当接部材を含む。第１当接部材には棒状部に対向する複数の第１突起が所定の位置に形成され、第２当接部材には第２平面部に当接する第２突起が所定の位置に形成され、第１平面部には複数の第１突起のうち少なくとも２つが当接する。   In order to solve the above problems, a wire harness fixing structure according to an aspect of the present invention includes a rod-shaped portion that is a rod-shaped portion of a stabilizer provided in a vehicle, and a bracket for fixing the wire harness to the rod-shaped portion. . A first flat surface portion and a second flat surface portion are provided on the outer peripheral surface of the rod-shaped portion so as to sandwich the central axis of the rod-shaped portion, and the bracket includes a first contact member and a second contact member. The first abutting member has a plurality of first protrusions facing the rod-shaped part at a predetermined position, and the second abutting member has a second protrusion abutting on the second flat part at a predetermined position, At least two of the plurality of first protrusions are in contact with the first plane portion.

この態様によると、複数の第１突起のうち少なくとも２つが第１平面部に当接し、第２当接部材の第２突起が第２平面部に当接するから、スタビライザの棒状部に対するブラケットの回転ずれを効果的に抑制することができる。   According to this aspect, since at least two of the plurality of first protrusions contact the first flat surface portion and the second protrusion of the second contact member contacts the second flat surface portion, the rotation of the bracket relative to the rod-shaped portion of the stabilizer. Deviation can be effectively suppressed.

本発明によれば、スタビライザの棒状部に対するワイヤハーネスを固定するためのブラケットの回転ずれを効果的に抑制しうるワイヤハーネス固定構造の技術を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the technique of the wire harness fixing structure which can suppress effectively the rotation shift of the bracket for fixing the wire harness with respect to the rod-shaped part of a stabilizer can be provided.

第２上面部１４ｃは第２側面部１４ａの上側から左側に延在する平板状の部分である。第２上面部１４ｃは棒状部８０の上側と対向する。第２上面部１４ｃは、第２下面部１４ｂおよび第１下面部１２ｂと略平行に設けられる。第２係合部１４ｆは第２上面部１４ｃの左側に連設される部分である。第２係合部１４ｆは、平板状の部分が第１係合孔１２ｇに挿入された状態でカール曲げ加工されることで形成される。既述したように、第１係合孔１２ｇと第２係合部１４ｆとは、第１当接部材１２を第２当接部材１４に回動自在に支持するヒンジを構成する。   The second upper surface portion 14c is a flat plate portion extending from the upper side to the left side of the second side surface portion 14a. The second upper surface portion 14 c faces the upper side of the rod-shaped portion 80. The second upper surface portion 14c is provided substantially in parallel with the second lower surface portion 14b and the first lower surface portion 12b. The second engaging portion 14f is a portion that is connected to the left side of the second upper surface portion 14c. The second engaging portion 14f is formed by curl bending in a state where a flat plate-like portion is inserted into the first engaging hole 12g. As described above, the first engagement hole 12g and the second engagement portion 14f constitute a hinge that rotatably supports the first contact member 12 on the second contact member 14.

第２下面部１４ｂは第２側面部１４ａの下側から左側に延在する平板状の部分である。第２下面部１４ｂは棒状部８０の下側と対向する。第２下面部１４ｂは第２上面部１４ｃと略平行に設けられる。第２上面部１４ｃと第２側面部１４ａと第２下面部１４ｂとは、角張った逆Ｃ字状に一体に形成される。第２固定部１４ｄは第２下面部１４ｂの左側から下側に延在する平板状の部分である。第２固定部１４ｄには略左右に貫通する第２ボルト孔１４ｅが設けられる。第２ボルト孔１４ｅは後述する第２当接部材１４の第２ボルト孔１４ｅと重ねられる。第２ボルト孔１４ｅと第１ボルト孔１２ｅとにボルト（不図示）が挿入されナット（不図示）が締め込まれることにより、第２固定部１４ｄは第１固定部１２ｄに固定される。   The second lower surface portion 14b is a flat plate portion extending from the lower side to the left side of the second side surface portion 14a. The second lower surface portion 14 b faces the lower side of the rod-shaped portion 80. The second lower surface portion 14b is provided substantially in parallel with the second upper surface portion 14c. The second upper surface portion 14c, the second side surface portion 14a, and the second lower surface portion 14b are integrally formed in an angular inverted C shape. The second fixing portion 14d is a flat plate portion extending from the left side to the lower side of the second lower surface portion 14b. The second fixing portion 14d is provided with a second bolt hole 14e penetrating substantially left and right. The second bolt hole 14e is overlapped with a second bolt hole 14e of the second contact member 14 described later. When a bolt (not shown) is inserted into the second bolt hole 14e and the first bolt hole 12e and a nut (not shown) is tightened, the second fixing portion 14d is fixed to the first fixing portion 12d.

（囲繞部）
第１当接部材１２と第２当接部材１４との間には棒状部８０を囲繞するための囲繞部１０ａが設けられる。囲繞部１０ａは、その上端１０ｂから下端１０ｃの間で棒状部８０を挟持することができる。換言すると、棒状部８０は、囲繞部１０ａの上端１０ｂから下端１０ｃの間の任意の位置で囲繞部１０ａに挟持される。囲繞部１０ａは、第１側面部１２ａと、第１下面部１２ｂと、第２側面部１４ａと、第２下面部１４ｂと、第２上面部１４ｃとによって形成される略矩形状を有する。 (Go section)
Between the first contact member 12 and the second contact member 14, an encircling portion 10 a for enclosing the rod-shaped portion 80 is provided. The surrounding portion 10a can sandwich the rod-shaped portion 80 between the upper end 10b and the lower end 10c. In other words, the rod-shaped part 80 is clamped by the surrounding part 10a at an arbitrary position between the upper end 10b and the lower end 10c of the surrounding part 10a. The surrounding portion 10a has a substantially rectangular shape formed by the first side surface portion 12a, the first lower surface portion 12b, the second side surface portion 14a, the second lower surface portion 14b, and the second upper surface portion 14c.

（突起）
次に、突起１１ａ、１１ｂ、１１ｃ、１１ｄの配置について説明する。棒状の部材にブラケットを挟むように構成する場合に、棒状の部材に対するブラケットの回転ずれ防止の対策をとることが望ましい。そこで、実施形態のワイヤハーネス固定構造１００では、第１当接部材１２にはスタビライザ７８の棒状部８０に対向する複数の第１突起１１が所定の位置に形成され、第２当接部材１４には第２平面部８４に当接する第２突起９が所定の位置に形成され、複数の第１突起１１のうち少なくとも２つが第１平面部８２に当接するように配置される。この構成により、ブラケット１０は棒状部８０を囲む３点以上で棒状部８０の平面部に当接するから、棒状部８０に対するブラケット１０の回転ずれを効果的に抑制することができる。 (Projection)
Next, the arrangement of the protrusions 11a, 11b, 11c, and 11d will be described. In the case where the bracket is sandwiched between the rod-shaped members, it is desirable to take measures to prevent the rotation deviation of the bracket with respect to the rod-shaped members. Therefore, in the wire harness fixing structure 100 of the embodiment, the first contact member 12 is formed with a plurality of first protrusions 11 facing the rod-shaped portion 80 of the stabilizer 78 at predetermined positions. The second projections 9 that abut against the second plane portion 84 are formed at predetermined positions, and at least two of the plurality of first projections 11 are arranged to abut against the first plane portion 82. With this configuration, the bracket 10 abuts against the flat portion of the rod-shaped portion 80 at three or more points surrounding the rod-shaped portion 80, so that the rotational deviation of the bracket 10 with respect to the rod-shaped portion 80 can be effectively suppressed.

図６は、棒状部８０が囲繞部１０ａの最も上側に位置する状態の端面図である。図６の状態では、棒状部８０の上面は第２当接部材１４の第２上面部１４ｃ（＝上端１０ｂ）に当接する。この状態で、第１平面部８２には上側に配置される突起１１ａ、１１ｂが当接し、第２平面部８４に第２突起９が当接する。以下、突起１１ａ、１１ｂ、１１ｃ、１１ｄの具体的な配置の一例について説明する。   FIG. 6 is an end view showing a state in which the rod-like portion 80 is located on the uppermost side of the surrounding portion 10a. In the state of FIG. 6, the upper surface of the rod-shaped portion 80 is in contact with the second upper surface portion 14 c (= the upper end 10 b) of the second contact member 14. In this state, the projections 11 a and 11 b arranged on the upper side come into contact with the first flat part 82, and the second protrusion 9 comes into contact with the second flat part 84. Hereinafter, an example of a specific arrangement of the protrusions 11a, 11b, 11c, and 11d will be described.

まず、最上位置の突起１１ａが第１平面部８２に当接しうる条件を説明する。棒状部８０の上下の幅（Ｚ軸方向の寸法）をＡとし、第１平面部８２の上下の幅（Ｚ軸方向の寸法）をａとし、囲繞部１０ａの上端１０ｂから、突起１１ａまでの上下方向の距離（Ｚ軸方向の距離）をＰ１とするとき、Ｐ１が式１を満たすとき最上位置の突起１１ａが第１平面部８２に当接する（図５も参照）。
Ｐ１＞（Ａ−ａ）／２ ・・・（式１） First, the conditions under which the uppermost protrusion 11a can come into contact with the first flat surface portion 82 will be described. The vertical width (dimension in the Z-axis direction) of the rod-shaped portion 80 is A, the vertical width (dimension in the Z-axis direction) of the first plane portion 82 is a, and the upper end 10b of the surrounding portion 10a to the protrusion 11a. When the distance in the vertical direction (distance in the Z-axis direction) is P1, the uppermost protrusion 11a comes into contact with the first flat surface portion 82 when P1 satisfies Formula 1 (see also FIG. 5).
P1> (Aa) / 2 (Formula 1)

次に、最上位置の突起１１ａと上から２番目の突起１１ｂとが第１平面部８２に当接しうる条件を説明する。突起１１ａ、１１ｂの上下方向の間隔および突起１１ｃ、１１ｄの上下方向の間隔をＰとするとき、Ｐが第１平面部８２の上下範囲寸法であるａの半分未満である場合に、図６に示すように突起１１ａと突起１１ｂが第１平面部８２の上下範囲に当接する。つまり、Ｐが式２の条件を満たすとき少なくとも最上位置の突起１１ａと上から２番目の突起１１ｂとが第１平面部８２に当接する（図５も参照）。
Ｐ＜ａ／２ ・・・（式２）
なお、複数の第１突起１１の上下方向の各間隔は等しく設定されてもよく、この場合の各間隔はＰと等しく設定されてもよい。つまり、突起１１ａ、１１ｂ、１１ｃ、１１ｄの上下方向の間隔は等しく設定されてもよい（図５も参照）。 Next, the conditions under which the uppermost protrusion 11a and the second protrusion 11b from the top can contact the first flat surface portion 82 will be described. When the vertical distance between the protrusions 11a and 11b and the vertical distance between the protrusions 11c and 11d is P, when P is less than half of the vertical range dimension of the first plane portion 82, FIG. As shown, the protrusion 11 a and the protrusion 11 b are in contact with the upper and lower ranges of the first flat portion 82. That is, when P satisfies the condition of Expression 2, at least the uppermost protrusion 11a and the second protrusion 11b from the top abut on the first flat surface portion 82 (see also FIG. 5).
P <a / 2 (Formula 2)
The intervals in the vertical direction of the plurality of first protrusions 11 may be set equal. In this case, the intervals may be set equal to P. That is, the vertical intervals of the protrusions 11a, 11b, 11c, and 11d may be set equal (see also FIG. 5).

次に、第２突起９が第２平面部８４に当接しうる条件を説明する。第２突起９が第２側面部１４ａの上下範囲の中央（＝囲繞部１０ａの中央）に設けられる場合に、囲繞部１０ａの上端１０ｂと下端１０ｃの間の上下方向の距離をＬとすると、第２突起９から第２上面部１４ｃまでの距離はＬ／２と表される。この距離が、棒状部８０の上端から第２平面部８４の上端までのＺ軸方向の寸法より大きい場合に、第２突起９が第２平面部８４に当接する。つまり、式３の条件を満たすとき第２突起９が第２平面部８４に当接する（図５も参照）。
ａ／２＞（Ｌ−Ａ）／２ ・・・（式３） Next, the conditions under which the second protrusion 9 can come into contact with the second flat portion 84 will be described. When the second protrusion 9 is provided at the center of the upper and lower range of the second side surface portion 14a (= the center of the surrounding portion 10a), if the vertical distance between the upper end 10b and the lower end 10c of the surrounding portion 10a is L, The distance from the 2nd protrusion 9 to the 2nd upper surface part 14c is represented as L / 2. When this distance is larger than the dimension in the Z-axis direction from the upper end of the rod-shaped part 80 to the upper end of the second flat part 84, the second protrusion 9 contacts the second flat part 84. That is, when the condition of Expression 3 is satisfied, the second protrusion 9 comes into contact with the second flat surface portion 84 (see also FIG. 5).
a / 2> (LA) / 2 (Formula 3)

図７は、棒状部８０が最も下側に位置する状態の端面図である。図７の状態では、棒状部８０の下面は第２当接部材１４の第２下面部１４ｂ（＝下端１０ｃ）に当接する。この場合に、第２下面部１４ｂから最下位置の突起１１ｄまでの上下方向の距離（Ｚ軸方向の距離）もＰ１として、式１、式２および式３に示される不等式を満たすとき、最下位置の突起１１ｄと下から２番目の突起１１ｃとが第１平面部８２に当接し、第２突起９が第２平面部８４に当接する（図５も参照）。   FIG. 7 is an end view showing a state in which the rod-like portion 80 is located on the lowermost side. In the state of FIG. 7, the lower surface of the rod-shaped portion 80 is in contact with the second lower surface portion 14 b (= lower end 10 c) of the second contact member 14. In this case, when the vertical distance (distance in the Z-axis direction) from the second lower surface portion 14b to the lowermost protrusion 11d is also P1, when the inequalities shown in Equation 1, Equation 2, and Equation 3 are satisfied, The lower projection 11d and the second projection 11c from the bottom contact the first flat surface portion 82, and the second protrusion 9 contacts the second flat surface portion 84 (see also FIG. 5).

このように、上下方向に複数の第１突起１１を配置し、これらが、式１、式２および式３を満たすとき、第１当接部材１２の複数の第１突起１１のうち少なくとも２つが第１平面部８２に当接し、第２当接部材１４の第２突起９が第２平面部８４に当接する。なお、棒状部８０とブラケット１０の形状は、式１、式２および式３に製造上の誤差を加味して設定することができる。   Thus, when the plurality of first protrusions 11 are arranged in the vertical direction and these satisfy Expression 1, Expression 2, and Expression 3, at least two of the plurality of first protrusions 11 of the first contact member 12 are The second projection 9 of the second abutting member 14 abuts on the second flat surface portion 84 and abuts on the first flat surface portion 82. In addition, the shape of the rod-shaped part 80 and the bracket 10 can be set by adding a manufacturing error to Equation 1, Equation 2, and Equation 3.

製造管理上の観点から、１種類のブラケットで形状の異なる複数のスタビライザに取付けできることが望ましい。そこで、実施形態のワイヤハーネス固定構造１００では、ブラケット１０は、式１、式２および式３を満たす範囲で別形状の棒状部に取付けすることができる。図８は、別形状の棒状部２８０がブラケット１０の最も上側に位置する状態を示す端面図である。棒状部２８０は棒状部８０より上下方向に大きい形状を有する。特に、ワイヤハーネス固定構造１００に棒状部２８０を含む場合はワイヤハーネス固定構造１００ｂと表記する。図８に示すように、ワイヤハーネス固定構造１００ｂにおいても、第１当接部材１２の複数の第１突起１１のうち少なくとも２つが第１平面部８２に当接し、第２当接部材１４の第２突起９が第２平面部８４に当接する。なお、別形状の棒状部２８０がブラケット１０の最も下側に位置する場合も、棒状部８０についてした説明と同様に、第１当接部材１２の複数の第１突起１１のうち少なくとも２つが第１平面部８２に当接し、第２当接部材１４の第２突起９が第２平面部８４に当接する。   From the viewpoint of manufacturing management, it is desirable that one type of bracket can be attached to a plurality of stabilizers having different shapes. Therefore, in the wire harness fixing structure 100 of the embodiment, the bracket 10 can be attached to a bar-shaped portion having a different shape as long as Expression 1, Expression 2, and Expression 3 are satisfied. FIG. 8 is an end view showing a state in which the bar-shaped portion 280 having another shape is located on the uppermost side of the bracket 10. The rod-shaped portion 280 has a shape that is larger in the vertical direction than the rod-shaped portion 80. In particular, when the wire harness fixing structure 100 includes the rod-shaped portion 280, it is expressed as a wire harness fixing structure 100b. As shown in FIG. 8, also in the wire harness fixing structure 100b, at least two of the plurality of first protrusions 11 of the first contact member 12 are in contact with the first flat portion 82, and the second contact member 14 is The two protrusions 9 come into contact with the second flat surface portion 84. Even when the bar-shaped part 280 having another shape is positioned at the lowermost side of the bracket 10, at least two of the plurality of first protrusions 11 of the first contact member 12 are the same as in the description of the bar-shaped part 80. The second projection 9 of the second abutting member 14 abuts on the second plane portion 84.

次に、このように構成されたワイヤハーネス固定構造１００の特徴を説明する。複数の第１突起１１のうち少なくとも２つが第１平面部８２に当接し、第２当接部材１４の第２突起９が第２平面部８４に当接するから、棒状部８０に対するブラケット１０の回転ずれを効果的に抑制することができる。つまり、回転時に軸となる第１当接部材１２の一方の突起と、第２当接部材１４の突起に対し回り止めのとなる第１当接部材１２の他方の突起とにより、回転止め機構の接触点を明確に設定することができる。このため回転軸となる点と回り止めのとなる点の間の距離を安定的に確保して、回転入力に対する抵抗する力の低下を抑制することができる。また、複数の第１突起１１の配置を工夫することで、形状の異なる複数のスタビライザに対応することが可能になる。さらに、少ない点数の部材によって回転止め機構を構成できるから、ワイヤハーネス固定構造の製造コストおよび生産性の観点で有利である。   Next, the characteristics of the wire harness fixing structure 100 configured as described above will be described. Since at least two of the plurality of first protrusions 11 are in contact with the first flat surface portion 82 and the second protrusion 9 of the second contact member 14 is in contact with the second flat surface portion 84, the bracket 10 is rotated with respect to the rod-shaped portion 80. Deviation can be effectively suppressed. That is, the rotation preventing mechanism is constituted by one projection of the first contact member 12 serving as a shaft at the time of rotation and the other projection of the first contact member 12 that prevents rotation of the projection of the second contact member 14. The contact point can be set clearly. For this reason, it is possible to stably secure a distance between the point serving as the rotation axis and the point serving as the rotation stopper, and to suppress a decrease in the force resisting the rotation input. Further, by devising the arrangement of the plurality of first protrusions 11, it is possible to cope with a plurality of stabilizers having different shapes. Furthermore, since the rotation stop mechanism can be configured with a small number of members, it is advantageous from the viewpoint of manufacturing cost and productivity of the wire harness fixing structure.
