しかしながら、前記従来の制振構造を車両の振動低減に適用すると、車両の重量増加になると共に部品点数の増加、取付け工数の増加等にもなる。   However, when the conventional vibration damping structure is applied to reduce the vibration of the vehicle, the weight of the vehicle is increased, and the number of parts and the number of mounting steps are increased.

そこで、本発明は、前記した課題を解決すべくなされたものであり、車両の重量、部品点数、取付け工数等を増加させることなく車両側の振動を低減できるワイヤーハーネス配策構造を提供することを目的とする。   Accordingly, the present invention has been made to solve the above-described problems, and provides a wire harness arrangement structure that can reduce vibration on the vehicle side without increasing the weight of the vehicle, the number of parts, the number of mounting steps, and the like. With the goal.

本発明は、ワイヤーハーネスを間隔を置いて固定部材で車両側の被取付部材に固定して配策するワイヤーハーネス配策構造であって、ワイヤーハーネスは、少なくとも２つの前記固定部材の間に介在される質量体として構成され、前記各固定部材には、前記ワイヤーハーネスと前記被取付部材との間に介在される弾性体が設けられていることを特徴とするワイヤーハーネス配策構造である。   The present invention is a wire harness routing structure in which a wire harness is fixed to a vehicle-side attached member with a fixing member at intervals, and the wire harness is interposed between at least two fixing members. The wire harness routing structure is characterized in that each of the fixing members is provided with an elastic body interposed between the wire harness and the attached member.

他の本発明は、ワイヤーハーネスを間隔を置いて固定部材で車両側の被取付部材に固定して配策するワイヤーハーネス配策構造であって、隣り合う２つの前記固定部材の間隔は、前記被取付部材側の固有振動数における波長にあわせた寸法に設定されていることを特徴とするワイヤーハーネス配策構造である。   Another aspect of the present invention is a wire harness routing structure in which a wire harness is spaced and fixed with a fixed member to a mounted member on a vehicle side, and the interval between two adjacent fixing members is The wire harness arrangement structure is characterized in that it is set to a size according to the wavelength at the natural frequency on the attached member side.

本発明によれば、２つの固定部材間に支持されたワイヤーハーネスの箇所は、ダイナミックダンパーの質量体として機能し、被取付部材側の振動が低減される。被取付部材に配策されるワイヤーハーネスを利用しているため、車両の重量、部品点数、取付け工数等を増加させることなく車両側の振動を低減できる。   According to the present invention, the portion of the wire harness supported between the two fixing members functions as a mass body of the dynamic damper, and vibration on the attached member side is reduced. Since the wire harness arranged for the member to be attached is used, the vibration on the vehicle side can be reduced without increasing the weight of the vehicle, the number of parts, the number of attachment steps, and the like.

他の本発明によれば、ワイヤーハーネスが被取付部材側の振動を打ち消すように同じ固有振動数で振動し、被取付部材側の振動が低減される。被取付部材に配策されるワイヤーハーネスを利用しているため、車両の重量、部品点数、取付け工数等を増加させることなく車両側の振動を低減できる。   According to another aspect of the present invention, the wire harness vibrates at the same natural frequency so as to cancel the vibration on the attached member side, and the vibration on the attached member side is reduced. Since the wire harness arranged for the member to be attached is used, the vibration on the vehicle side can be reduced without increasing the weight of the vehicle, the number of parts, the number of attachment steps, and the like.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（第１実施形態）
図１は本発明の第１実施形態を示す。ワイヤーハーネスＷＨは、第１幹線Ｗｈ１と第２幹線Ｗｈ２と第１幹線Ｗｈ１及び第２幹線Ｗｈ２間を連結する第３幹線Ｗｈ３とを備えている。第１幹線Ｗｈ１及び第２幹線Ｗｈ２は、それぞれ被取付部材である車体パネル１０を貫通する経路で配策されている。第１幹線Ｗｈ１及び第２幹線Ｗｈ２には、車体パネル１０の貫通箇所にグロメット１がそれぞれ装着されている。 (First embodiment)
FIG. 1 shows a first embodiment of the present invention. The wire harness WH includes a first trunk line Wh1, a second trunk line Wh2, and a third trunk line Wh3 that connects the first trunk line Wh1 and the second trunk line Wh2. The first trunk line Wh1 and the second trunk line Wh2 are routed along paths that penetrate the vehicle body panel 10 that is a member to be attached. Grommets 1 are respectively attached to the first trunk line Wh1 and the second trunk line Wh2 at locations where the vehicle body panel 10 penetrates.

第３幹線Ｗｈ３は、車体パネル１０の面に沿って配策されている。第３幹線Ｗｈ３は、電線束３１と電線束３１の外周を覆う外装品であるプロテクタ３２とを有する。第３幹線Ｗｈ３は、配策方向の間隔を置いた複数位置で固定部材１１，１２を介して車体パネル１０に固定されている。各固定部材１１，１２には、第３幹線Ｗｈ３と車体パネル１０との間に介在される弾性体（図示せず）が設けられている。弾性体は、例えば制振ゴムによって形成される。   The third trunk line Wh3 is routed along the surface of the vehicle body panel 10. The third trunk line Wh3 includes a wire bundle 31 and a protector 32, which is an exterior product that covers the outer periphery of the wire bundle 31. The third trunk line Wh3 is fixed to the vehicle body panel 10 via the fixing members 11 and 12 at a plurality of positions at intervals in the routing direction. Each fixing member 11, 12 is provided with an elastic body (not shown) interposed between the third trunk line Wh 3 and the vehicle body panel 10. The elastic body is formed of, for example, vibration damping rubber.

隣り合う２つの固定部材１１，１２間の第３幹線Ｗｈ３の箇所は、２つの固定部材１１，１２の間に介在される質量体として構成されている。詳細には、ワイヤーハーネスＷＨの第３幹線Ｗｈ３の箇所は、電線束３１のみの構成に較べてプロテクタ３２によって大質量で、且つ、高い剛性の構造体である。つまり、ワイヤーハーネスＷＨの第３幹線Ｗｈ３及び固定部材１１，１２がダイナミックダンパーとして機能する場合の質量体として構成されている。   A portion of the third trunk line Wh3 between the two adjacent fixing members 11 and 12 is configured as a mass body interposed between the two fixing members 11 and 12. Specifically, the location of the third trunk line Wh3 of the wire harness WH is a structure having a large mass and high rigidity by the protector 32 as compared with the configuration of the wire bundle 31 alone. That is, the third trunk line Wh3 and the fixing members 11 and 12 of the wire harness WH are configured as mass bodies when functioning as dynamic dampers.

又、第３幹線Ｗｈ３は、第１幹線Ｗｈ１と第２幹線Ｗｈ２に両端が支持された形態で配策されているため、このような配策形態によっても振動し難い構成となっている。これによっても、ワイヤーハーネスＷＨの第３幹線Ｗｈ３の箇所は、高い剛性の構造体である。   Further, since the third trunk line Wh3 is routed in a form in which both ends are supported by the first trunk line Wh1 and the second trunk line Wh2, the third trunk line Wh3 is configured not to vibrate even by such a routing form. Also by this, the location of the 3rd trunk line Wh3 of the wire harness WH is a highly rigid structure.

以上説明したように、２つの固定部材１１，１２間に支持されたワイヤーハーネスＷＨの第３幹線Ｗｈ３の箇所は、ダイナミックダンパーの質量体として機能し、車体パネル１０側の振動が低減される。車体パネル１０に配策されるワイヤーハーネスＷＨを利用しているため、車両の重量、部品点数、取付け工数等を増加させることなく車両側の振動を低減できる。   As described above, the location of the third trunk line Wh3 of the wire harness WH supported between the two fixing members 11 and 12 functions as a mass body of the dynamic damper, and vibration on the vehicle body panel 10 side is reduced. Since the wire harness WH routed to the vehicle body panel 10 is used, vibration on the vehicle side can be reduced without increasing the weight of the vehicle, the number of parts, the number of mounting steps, and the like.

（第２実施形態）
図２は本発明の第２実施形態を示す。ワイヤーハーネスＷＨは、車体パネル１０の面に沿って配策されている。ワイヤーハーネスＷＨは、配策方向の間隔を置いた複数位置で固定部材１３，１４を介して被取付部材である車体パネル１０に固定されている。 (Second Embodiment)
FIG. 2 shows a second embodiment of the present invention. The wire harness WH is routed along the surface of the vehicle body panel 10. The wire harness WH is being fixed to the vehicle body panel 10 which is a to-be-attached member via the fixing members 13 and 14 in the several position which put the space | interval of the routing direction.

隣り合う２つの固定部材１３，１４の間隔Ｌは、車体パネル１０側の固有振動数における波長にあわせた寸法に設定されている。ワイヤーハーネスＷＨは、固定部材１３，１４によって両端固定で支持されているため、以下の数式により間隔Ｌを算出することができる。   The distance L between the two adjacent fixing members 13 and 14 is set to a size according to the wavelength at the natural frequency on the vehicle body panel 10 side. Since the wire harness WH is supported by the fixing members 13 and 14 at both ends, the distance L can be calculated by the following mathematical formula.

ｆｎ＝ｋ・ｎ2／２π・√（Ｅ・Ｉ／ρ・Ａ・Ｌ4）
ここで、ｋｎ：固有値に対応した定数、Ｅ：縦弾性係数、Ｉ：断面二次モーメント、Ａ：断面積、Ｌ：固定部材１３，１４間の間隔（固定部材１３，１４間のワイヤーハーネスＷＨの長さ）、ρ：密度である。 fn = k · n 2 / 2π · √ (E · I / ρ · A · L 4 )
Here, kn: constant corresponding to the eigenvalue, E: longitudinal elastic modulus, I: sectional moment of inertia, A: sectional area, L: spacing between the fixing members 13, 14 (wire harness WH between the fixing members 13, 14) Length), ρ: density.

以上説明したように、車体パネル１０側が固有振動数で振動すると、この振動が固定部材１３，１４を介してワイヤーハーネスＷＨに伝達される。すると、ワイヤーハーネスＷＨが車体パネル１０側の振動を打ち消すように同じ固有振動数で振動し、車体パネル１０側の振動が低減される。車体パネル１０に配策されるワイヤーハーネスＷＨを利用しているため、車両の重量、部品点数、取付け工数等を増加させることなく車両側の振動を低減できる。   As described above, when the vehicle body panel 10 vibrates at the natural frequency, this vibration is transmitted to the wire harness WH via the fixing members 13 and 14. Then, the wire harness WH vibrates at the same natural frequency so as to cancel the vibration on the vehicle body panel 10 side, and the vibration on the vehicle body panel 10 side is reduced. Since the wire harness WH routed to the vehicle body panel 10 is used, vibration on the vehicle side can be reduced without increasing the weight of the vehicle, the number of parts, the number of mounting steps, and the like.

隣り合う２つの固定部材１１，１２の間隔Ｌは、被取付部材毎に、問題となる振動の周波数に合わせて設定することにより、被取付部材毎に振動を有効に低減できる。   By setting the interval L between the two adjacent fixing members 11 and 12 in accordance with the frequency of the problem vibration for each mounted member, the vibration can be effectively reduced for each mounted member.
