Description

本発明は、車外からドアの内部に侵入した水の車室側への漏出を防止する車両用ドアの防水構造に関する。   The present invention relates to a waterproof structure for a vehicle door that prevents water that has entered the inside of the door from leaking from the outside of the vehicle to the vehicle compartment side.

車両である自動車用のドアには、車外からドアの内部に侵入した水の車室側への漏出を防止する防水構造が採用されている。そして通常、図８に示すように、ドア３０は、車体の外面側を形成するドアアウタパネル３１と、車室側を形成してドアアウタパネル３１と対面しサービスホール３２が形成されたドアインナパネル３３と、車外からサービスホール３２を経てドアインナパネル３３との間に浸入した水が車室側に漏出しないようにするために、ドアインナパネル３３の車室側の面を覆うサービスホールカバー３４と、サービスホール３２を取り囲む枠形状となるよう車室側の面に沿って延び、車室側の面に対しサービスホールカバー３４の外縁部を接着させる線状接着材３５と、車室側の面に沿って延び、その長手方向の一部分が線状接着材３５のうちの上下方向に延びる接着材部分３６と交差するように設けられるワイヤーハーネス３７とを備えている。なお、ワイヤーハーネス３７の一方端部は車室側の面に設けられたコネクタ３８に接続され、その途中の複数個所がクランプ３９によりドアインナパネル３３に取り付けられている。   DESCRIPTION OF RELATED ART The door for motor vehicles which are vehicles employ | adopts the waterproof structure which prevents the invasion of the water which invaded the inside of the door from the outside of a vehicle to the vehicle interior side. In general, as shown in FIG. 8, the door 30 includes a door outer panel 31 forming the outer surface side of the vehicle body, and a door inner panel 33 forming the vehicle interior side and facing the door outer panel 31 and forming the service hole 32. A service hole cover 34 that covers a surface of the door inner panel 33 on the vehicle interior side so that water that has entered between the outside of the vehicle and the door inner panel 33 via the service hole 32 does not leak to the vehicle interior side. A linear adhesive 35 extending along the surface on the vehicle interior side so as to form a frame surrounding the service hole 32 and bonding the outer edge of the service hole cover 34 to the surface on the vehicle interior side; , And a wire harness 37 provided so that a part in the longitudinal direction thereof intersects with an adhesive part 36 extending in the vertical direction of the linear adhesive 35. One end of the wire harness 37 is connected to a connector 38 provided on a surface on the vehicle cabin side, and a plurality of portions in the middle thereof are attached to the door inner panel 33 by clamps 39.

ところが、接着材部分３６とワイヤーハーネス３７の一部分とが交差する交差部４０では、接着材部分３６とワイヤーハーネス３７とサービスホールカバー３４との三者のうち、少なくともいずれか二者の間にわずかながらでも隙間が生じがちとなるため、雨天時など、車外からドアインナパネル３３とサービスホールカバー３４との間に水が浸入し、この水が、自重により接着材部分３６やワイヤーハーネス３７の一部分を伝って交差部に向け流下した場合には、交差部４０の隙間を通して落下した水が車室側に漏出し、電気部品であるコネクタ３８が水で濡れるおそれがある。   However, at the intersection 40 where the adhesive part 36 and a part of the wire harness 37 intersect, at least between the adhesive part 36, the wire harness 37, and the service hole cover 34, at least between any two of them. However, water tends to enter between the door inner panel 33 and the service hole cover 34 from outside the vehicle, such as when it is raining, and this water is partially removed by the adhesive material portion 36 and the wire harness 37 due to its own weight. When the water flows down toward the intersection along the route, water that has fallen through the gap between the intersections 40 leaks to the cabin side, and the connector 38 as an electrical component may be wetted with water.

そこで従来、例えば特許文献１に記載のように、ドア３０を車室側から見た場合に、ワイヤーハーネス３７の一部分が、枠形状をなす線状接着材３５の内側から外側に向かうに従い、図８に示す如く上方に向かって延びるようにし、ワイヤーハーネス３７の一部分の上方近傍域における接着材部分３６を屈曲させると共に、この屈曲部４１における山折れ側の頂部４１ａが、ワイヤーハーネス３７の一部分と接着材部分３６との交差部４０を通る上下方向の仮想線を基準として前方側（図８中のＦｒ矢印方向側）に位置するような構造が提案されている。   Conventionally, as described in Patent Document 1, for example, when the door 30 is viewed from the passenger compartment side, a part of the wire harness 37 moves from the inside to the outside of the frame-shaped linear adhesive 35 as shown in FIG. As shown in FIG. 8, the adhesive portion 36 in the vicinity of the upper portion of the part of the wire harness 37 is bent, and the top 41 a of the bent part 41 on the mountain fold side is combined with a part of the wire harness 37. A structure has been proposed that is located on the front side (the side in the direction of the Fr arrow in FIG. 8) with reference to a vertical imaginary line passing through the intersection 40 with the adhesive portion 36.

ところで、上記した特許文献１に記載のように、ワイヤーハーネス３７の一部分の上方近傍域における接着材部分３６を屈曲させて組み付ける工程は手作業で行われるのが通常であり、屈曲部４１の屈曲度合いは作業者の判断に委ねられているが、ワイヤーハーネスが柔軟性に欠け重くその扱いが難しいことなどに起因して、ワイヤーハーネス３７の一部分の上方近傍域における接着材部分３６の屈曲部４１の屈曲度合いが作業者ごとにばらつき、或いは、同じ作業者でも車両ごとでも屈曲度合いにばらつきが生じ易く、屈曲部４１の屈曲度合いが不十分な場合には、水の車室側への漏出を完全に抑えることができないことがあり、その結果コネクタ３８の水濡れを招くおそれがある。   By the way, as described in Patent Literature 1 described above, the step of bending and assembling the adhesive portion 36 in the upper vicinity area of a part of the wire harness 37 is usually performed manually, and the bending of the bending portion 41 is performed. The degree is left to the discretion of the operator, but due to the lack of flexibility and difficulty in handling the wire harness, etc., the bent portion 41 of the adhesive portion 36 in the upper vicinity area of a part of the wire harness 37 is determined. The degree of bending varies from worker to worker, or the degree of bending tends to vary between the same worker or from vehicle to vehicle. In some cases, the connector 38 cannot be completely suppressed, and as a result, the connector 38 may be wet.

本発明は、作業者の組付け作業におけるばらつきの影響を受けることなく、ドアの内部に侵入した水の車室側への漏出を確実に防止できるようにすることを目的とする。   SUMMARY OF THE INVENTION It is an object of the present invention to reliably prevent water leaked into a door from leaking into a vehicle compartment without being affected by variations in an assembling operation performed by an operator.

本発明に係る車両用ドアの防水構造の一実施形態について、図１、図２を参照して詳細に説明する。図１はドアの一部を切断した側面であり、図２は図１の一部を拡大した側面図である。   An embodiment of a waterproof structure for a vehicle door according to the present invention will be described in detail with reference to FIGS. FIG. 1 is a side view in which a part of the door is cut, and FIG. 2 is a side view in which a part of FIG. 1 is enlarged.

本実施形態における自動車（車両）用ドアは、図７に示すものとほぼ同様に構成されている。すなわち、図１に示すように、ドア１は、車体の外面側を形成するドアアウタパネル２と、車室側を形成してドアアウタパネル２と対面しサービスホール３が形成されたドアインナパネル４と、車外からサービスホール３を経てドアインナパネル４との間に浸入した水が車室側に漏出しないようにするために、ドアインナパネル４の車室側の面を覆うサービスホールカバー５と、サービスホール３を取り囲むほぼ枠形状となるよう車室側の面に沿って延び、車室側の面に対しサービスホールカバー５の外縁部を接着させるブチルゴムから成る線状接着材６と、車室側の面に沿って延び、その長手方向の一部分が線状接着材６と干渉する位置に配設されるワイヤーハーネス７と、車室側の面に設けられワイヤーハーネス７の一方端部７ａが接続されたコネクタ８と、ワイヤーハーネス７の途中の複数個所をドアインナパネル４に取り付けるクランプ９とを備える。このとき、ワイヤーハーネス７のコネクタ８と接続された一方端部７ａが、最後方に位置するクランプ９を境に後方に向かうに従い上方に向かって延びるように配置されている。   The door for an automobile (vehicle) according to the present embodiment is configured in substantially the same manner as that shown in FIG. That is, as shown in FIG. 1, the door 1 includes a door outer panel 2 forming an outer surface side of a vehicle body, and a door inner panel 4 forming a vehicle interior side and facing the door outer panel 2 and forming a service hole 3. A service hole cover 5 that covers a surface of the door inner panel 4 on the vehicle interior side so that water that has entered between the outside of the vehicle and the door inner panel 4 via the service hole 3 does not leak to the vehicle interior side; A linear adhesive material 6 made of butyl rubber, which extends along the vehicle compartment side so as to have a substantially frame shape surrounding the service hole 3 and adheres the outer edge of the service hole cover 5 to the vehicle compartment side surface; A wire harness 7 extending along a side surface of the vehicle and disposed at a position where a part of the longitudinal direction of the wire harness interferes with the linear adhesive material 6, and one end 7 a of the wire harness 7 provided on a vehicle side surface Connection It comprises a connector 8 that is, a clamp 9 for attaching the middle of a plurality of locations of the wire harness 7 to the door inner panel 4. At this time, the one end 7a of the wire harness 7 connected to the connector 8 is arranged so as to extend upward with respect to the clamp 9 located at the rearmost side.

図２は図１中の２点鎖線で囲む領域を拡大したものであり、図２に示すように、ワイヤーハーネス７の一方端部７ａと干渉する線状接着材６の上下方向部分が、上部側６１と下部側６２に分割され、分割された線状接着材６の上部側６１を伝って流れる水が、図２中の破線およびハッチングで示す範囲で上部側６１の分割端６１ａから流れ落ちてもコネクタ８にかかることがないように、線状接着材６の上部側６１の分割端６１ａが、コネクタ８よりも下方で、後側のクランプ９よりも上方かつ前方（図２中のＦｒ矢印方向）に配置されている。ここで、線状接着材６の下部側６２を乗り越えるように、斜め上向きのワイヤーハーネス７の一方端部７ａが配設される。   FIG. 2 is an enlarged view of a region surrounded by a two-dot chain line in FIG. 1. As shown in FIG. 2, the vertical portion of the linear adhesive 6 that interferes with one end 7 a of the wire harness 7 The water flowing along the upper side 61 of the divided linear adhesive material 6 divided into the side 61 and the lower side 62 flows down from the divided end 61a of the upper side 61 within a range indicated by a broken line and hatching in FIG. The split end 61a of the upper side 61 of the linear adhesive 6 is located below the connector 8 and above and in front of the rear clamp 9 so as not to be caught on the connector 8 (Fr arrow in FIG. 2). Direction). Here, one end 7a of the wire harness 7 that is obliquely upward is disposed so as to pass over the lower side 62 of the linear adhesive 6.

また、線状接着材６の上部側６１を伝って上部側６１の分割端６１ａから流れ落ちる水が、線状接着材６の外側へ流入するのを阻止するために、線状接着材６の下部側６２の分割端６２ａが後側のクランプ９の上方であって上部側６１の分割端６１ａよりも上方位置で上部側６１に接触するように下部側６２が配置されている。これにより、線状接着材６の上部側６１を伝って上部側６１の分割端６１ａから流れ落ちる水が下部側６２により遮断されて線状接着材６の外側へ流入が阻止される。なお、線状接着材６の下部側６２の分割端６２ａは、少なくとも上部側６１の分割端６１ａよりも上方位置で上部側６１に接触していればよい。   Further, in order to prevent water flowing along the upper side 61 of the linear adhesive 6 and flowing down from the divided end 61a of the upper side 61 from flowing into the outside of the linear adhesive 6, the lower part of the linear adhesive 6 is formed. The lower side 62 is arranged so that the divided end 62a of the side 62 is in contact with the upper side 61 at a position above the rear clamp 9 and above the divided end 61a of the upper side 61. As a result, water flowing along the upper side 61 of the linear adhesive 6 and flowing down from the divided end 61 a of the upper side 61 is blocked by the lower side 62 and is prevented from flowing outside the linear adhesive 6. The divided end 62a on the lower side 62 of the linear adhesive 6 only needs to be in contact with the upper side 61 at least at a position higher than the divided end 61a on the upper side 61.

このように、ワイヤーハーネス７の一方端部７ａが干渉する線状接着材６の上下方向部分を上部側６１と下部側６２に分割し、線状接着材６の上部側６１の分割端６１ａを、コネクタ８よりも下方、後側のクランプ９よりも上方でかつ前方（図１中のＦｒ矢印方向）に配置するとともに、下部側６２の分割端６２ａが上部側６１の分割端６１ａよりも上方位置で上部側６１に接触するように配置することにより、分割した線状接着材６の上部側６１を伝って流れ落ちる水滴は、図２中に破線で示す範囲内で落下するため、コネクタ８が落下した水に濡れることもなく、分割した線状接着材６の下部側６２により、線状接着材６の外側つまり図１、図２中のＦｒ矢印方向と反対向きに、上部側６１を伝って流れ落ちる水滴が流入するのを阻止できる。なお、ドア１の内部に侵入した水は、ドア１の下部に設けられた水抜き穴から外部に流出する。   As described above, the vertical portion of the linear adhesive 6 where the one end 7a of the wire harness 7 interferes is divided into the upper side 61 and the lower side 62, and the divided end 61a of the upper side 61 of the linear adhesive 6 is separated. , The connector is disposed below the connector 8, above the rear clamp 9, and forward (in the direction of the arrow Fr in FIG. 1), and the divided end 62 a of the lower side 62 is higher than the divided end 61 a of the upper side 61. By arranging so as to be in contact with the upper side 61 at the position, water droplets flowing down along the upper side 61 of the divided linear adhesive material 6 fall within a range shown by a broken line in FIG. Without being wet by the dropped water, the lower side 62 of the divided linear adhesive 6 travels along the upper side 61 outside the linear adhesive 6, that is, in the direction opposite to the direction of the arrow Fr in FIGS. 1 and 2. To prevent the falling water drops from flowing in That. The water that has entered the inside of the door 1 flows out through a drain hole provided at the lower part of the door 1.

しかも、分割した線状接着材６の上部側６１の分割端６１ａが、分割した線状接着材６の下部側６２とワイヤーハーネス７の一方端部７ａ側との交差部分よりも下方かつ前方に位置するため、かかるが交差部分において、線状接着材６の下部側６２と、ワイヤーハーネス７と、サービスホールカバー５との三者のうち少なくともいずれか二者の間にわずかな隙間があったとしても、分割した線状接着材６の上部側６１を伝って流れ落ちる水がこの隙間に流入することがなく良好な防水効果を得ることができる。   In addition, the divided end 61a of the upper side 61 of the divided linear adhesive 6 is located below and forward of the intersection between the lower side 62 of the divided linear adhesive 6 and the one end 7a of the wire harness 7. However, at the intersection, there was a slight gap between at least any two of the lower side 62 of the linear adhesive 6, the wire harness 7, and the service hole cover 5. Even if it does, water flowing down along the upper side 61 of the divided linear adhesive 6 does not flow into this gap, and a good waterproof effect can be obtained.

したがって、上記した実施形態によれば、線状接着材６の上部側６１の分割端６１ａを、コネクタ８よりも下方でかつ前方（図１中のＦｒ矢印方向）寄りに配置するとともに、下部側６２の分割端６２ａが上部側６１の分割端６１ａよりも上方位置で上部側６１に接触するように下部側６２を配置したため、線状接着材６のワイヤーハーネス７の一方端部７ａ側と干渉する部分の組み付け作業の際に、従来のように線状接着材を屈曲させる必要がなくなり、線状接着材６を分割することによって、作業者は線状接着材６の上部側６１および下部側６２を容易に配置することが可能になり、作業者の組み付け作業におけるばらつきの影響を受けることなく、ドア１の内部に侵入した水の車室側への漏出を確実に防止することが可能になる。   Therefore, according to the above-described embodiment, the split end 61a of the upper side 61 of the linear adhesive 6 is arranged below the connector 8 and closer to the front (in the direction indicated by the arrow Fr in FIG. 1), and at the lower side. Since the lower side 62 is arranged such that the split end 62a of the 62 contacts the upper side 61 at a position higher than the split end 61a of the upper side 61, the linear adhesive 6 interferes with one end 7a of the wire harness 7. It is not necessary to bend the linear adhesive at the time of the assembling work of the portion to be bonded as in the related art, and by dividing the linear adhesive 6, the worker can work on the upper side 61 and the lower side of the linear adhesive 6. 62 can be easily arranged, and it is possible to reliably prevent water that has entered the inside of the door 1 from leaking into the vehicle compartment side without being affected by variations in the assembling work of the operator.

さらに、変形例４では、図６に示すように、分割した線状接着材６の上部側６１の下端部を、後方（図６中のＦｒ矢印方向と反対方向）に少し屈曲させてワイヤーハーネス７の一方端部７ａに交差するように上部側６１を配置するとともに、その分割端６１ａが最後方のクランプ９とほぼ同じ高さであって当該クランプ９よりも後方に位置するように上部側６１を配置する。また、分割した線状接着材６の下部側６２の上端部を、前方（図６中のＦｒ矢印方向）に少し屈曲させてワイヤーハーネス７の一方端部７ａに交差するように配置するとともに、その分割端６２ａがコネクタ８とほぼ同じ高さ位置であって上部側６１の分割端６１ａよりも上方もしくは上方でかつ前方に位置するように下部側６２を配置している。これにより、変形例４でも、上記した実施形態と同等の効果を得ることができる。 (Modification 4)
Further, in Modification 4, as shown in FIG. 6, the lower end of the upper side 61 of the divided linear adhesive material 6 is slightly bent rearward (in the direction opposite to the direction indicated by the arrow Fr in FIG. 6) to form a wire harness. The upper side 61 is arranged so as to intersect with one end 7a of the upper end 7 and the upper end is arranged so that the divided end 61a is substantially the same height as the rearmost clamp 9 and is located behind the latter. 61 is arranged. In addition, the upper end of the lower side 62 of the divided linear adhesive 6 is slightly bent forward (in the direction of the arrow Fr in FIG. 6) so as to intersect with one end 7a of the wire harness 7, and The lower side 62 is arranged so that the divided end 62a is located at substantially the same height position as the connector 8 and is located above, above, or forward of the divided end 61a of the upper side 61. As a result, the same effects as those of the above-described embodiment can be obtained in the fourth modification.

（変形例５）
最後の変形例５では、図７に示すように、線状接着材６の上部側６１の分割端６１ａを、コネクタ８よりも上方であって、最後方のクランプ９よりも上方もしくは上方でかつ前方（図７中のＦｒ矢印方向）に上部側６１を配置するとともに、分割した線状接着材６の下部側６２が、ワイヤーハーネス７の一方端部７ａと交差し、その分割端６２ａが上部側６１の分割端６１ａよりも上方で上部側６１に接触するように下部側６２を配置している。これにより、変形例４でも、上記した実施形態と同等の効果を得ることができる。 (Modification 5)
In the last modified example 5, as shown in FIG. 7, the divided end 61a of the upper side 61 of the linear adhesive 6 is located above the connector 8 and above or above the last clamp 9 and The upper side 61 is arranged forward (in the direction of the arrow Fr in FIG. 7), and the lower side 62 of the divided linear adhesive material 6 intersects one end 7a of the wire harness 7, and the divided end 62a is located at the upper end. The lower side 62 is arranged so as to contact the upper side 61 above the divided end 61a of the side 61. As a result, the same effects as those of the above-described embodiment can be obtained in the fourth modification.

なお、本発明は上記した実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて上述したもの以外に種々の変更を行なうことが可能である。   The present invention is not limited to the above-described embodiment, and various changes other than those described above can be made without departing from the gist of the present invention.

例えば、上記した実施形態では、図２に示すように、線状接着材６を上部側６１と下部側６２に分割し、分割した上部側６１の分割端６１ａを、コネクタ８よりも下方、後側のクランプ９よりも上方でかつ前方（図２中のＦｒ矢印方向）に配置するとともに、下部側６２の分割端６２ａが上部側６１の分割端６１ａよりも上方位置で上部側６１に接触するように配置したが、線状接着材６を上部側６１および下部側６２の配置は、図２に示す配置や図３〜図７に示す変形例１〜５の配置に限定されるものではなく、要するに、線状接着材６を上部側６１と下部側６２に分割し、分割した線状接着材６の上部側６１を伝って上部側６１の分割端６１ａから流れ落ちる水がコネクタ８にかからないように、上部側６１を配置するとともに、線状接着材６の上部側６１を伝って上部側６１の分割端６１ａから流れ落ちる水が、線状接着材６の外側へ流入するのを阻止するように下部側６２を配置すればよい。   For example, in the above-described embodiment, as shown in FIG. 2, the linear adhesive 6 is divided into an upper side 61 and a lower side 62, and the divided end 61 a of the upper side 61 is located below and behind the connector 8. It is arranged above the front clamp 9 and forward (in the direction of the arrow Fr in FIG. 2), and the divided end 62a of the lower side 62 contacts the upper side 61 at a position higher than the divided end 61a of the upper side 61. However, the arrangement of the linear adhesive 6 on the upper side 61 and the lower side 62 is not limited to the arrangement shown in FIG. 2 and the arrangements of Modifications 1 to 5 shown in FIGS. In short, the linear adhesive 6 is divided into an upper side 61 and a lower side 62 so that water flowing along the upper side 61 of the divided linear adhesive 6 and flowing down from the divided end 61 a of the upper side 61 does not reach the connector 8. And the upper side 61 Along the upper side 61 of the timber 6 water flowing down from the split end 61a of the upper side 61, it may be disposed lower side 62 so as to prevent the flow into the outside of the linear adhesive 6.

また、上記した実施形態では、線状接着材６としてブチルゴムを使用した例を示したが、ブチルゴムに限定されるものではなく、要するにドアインナパネルおよびサービスホールカバーとのを接着性が良好であって線状を成すものであればよい。さらに、線状接着材６は必ずしも枠形状である必要はなく、前側、後側および上側の３辺から成るコ字形状であってもよい。   Further, in the above-described embodiment, an example in which butyl rubber is used as the linear adhesive 6 has been described. However, the present invention is not limited to butyl rubber. In short, the adhesiveness between the door inner panel and the service hole cover is good. What is necessary is just to form a linear shape. Furthermore, the linear adhesive 6 does not necessarily need to be in the shape of a frame, but may be in a U-shape including three sides on the front side, the rear side, and the upper side.
