【発明の属する技術分野】
本発明は車両用スライドドアのドアガラス昇降モータ等へ給電するための給電構造の改良に関する。
【0002】
【従来の技術】
近年、バン型車のRV車としての用途拡大に伴い、ドアガラス昇降を自動化する等のために、スライドドアに設けたドアガラス昇降モータやリミットスイッチ等へ車両ボデー側から給電する必要が生じている。そこで、図5,図6に示すような給電構造が提案されている(例えば特開平11−348683号)。ここで、図5は車両用スライドドアDの開放状態での下部垂直断面図、図6はその水平断面図である。スライドドアDのインナパネルにはL字形に屈曲した(図5)ステー1がボデーパネルPに向けて突設されており、ステー1の先端には補助板11を介してローラブラケット12が取り付けられている。ローラブラケット12は水平面内で回動可能に上記補助板11に結合されており、平面視で二股に別れた各脚部121,122(図6)の先端にはそれぞれ水平ローラ13,14が設けられて、これら水平ローラ13,14が、ステップパネル2(図5)の下面に設けられたロアガイドレール21内に位置している。ローラブラケット12の中央部は下方へ屈曲し、ここに垂直ローラ15が支持されて、ボデーパネルP上に位置している。スライドドアDは閉鎖時にはガイドレール21に案内されて、車両前方(図6の右方)へ移動した後、車両内方へ(図6の下方)引き寄せられる。
【0003】
スライドドアDのインナパネルにはドア開閉方向へガイドレール3が設けてある。このガイドレール3は下方へ開放するU字断面をなし(図5)、その開口部にはガイドレール3に沿って移動自在にスライダ4が設けられている。スライダ4の前端(図5の紙面向う側)からはフラットケーブル41が延出し、このフラットケーブル41は上方へU字状に折り返されて、ガイドレール3の頂壁に沿ってその後端部に至り、ここに設けた中継コネクタ42の前端に入力接続されている。中継コネクタ42の後端からはスライドドア内のドアガラス昇降モータ等へ給電線(図示略)が延びている。スライダ4とステップパネル2との間には支持部材7が配設されている。支持部材7は湾曲変形可能な可撓性のある金属ワイヤ71の両端に、円形リング部721,731を有する金属製端子72,73を固着したもので、金属製端子72の円形リング部721がスライダ4に設けたボルト61に回動可能に嵌装されるとともに、金属製端子73の円形リング部731はステップパネル2に設けたボルト22に回動可能に嵌装されている。スライダ4から車両ボデー側へ延びる給電線54は上記金属ワイヤ71を通したチューブ74内に挿通されて車両ボデー側へ渡り、上方へ湾曲してステップパネル2を貫通して図略のワイヤハーネスに接続されている。
【0004】
このような構造において、スライドドアDが開放状態から車両前方の閉鎖方向へ移動すると、ガイドレール3が前方へ移動(図6の右方)してもスライダ4は支持部材7に引張られるようにしてその位置の移動が制限される結果、スライダ4がガイドレール3に対して相対移動する。スライドドアDが前端に至り、車両内方の閉鎖位置へ引き寄せられると、支持部材7はボルト22回りに図6の時計方向(図中矢印)へ旋回する。この場合、支持部材7の旋回軌跡とスライドドアDの移動軌跡は必ずしも一致しないが、両者の相対変位は支持部材7の金属ワイヤ71が適当に湾曲変形することによって吸収される。
【0005】
【発明が解決しようとする課題】
ところで、上記従来の給電構造において、スライドドアDの開閉に伴い支持部材7がボルト61回りに正逆旋回する過程で、給電線54が図5の特にA部で大きな曲率で曲げられることがあり、この場合に給電線54が断線するおそれがあった。また、上記給電構造では、金属製端子72とこれの取り付け構造が比較的複雑であるという問題もあった。
【0006】
そこで本発明はこのような課題を解決するもので、簡易な構造で給電線の断線等を防止することができる車両用スライドドアの給電構造を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記目的を達成するために、本第1発明では、スライドドア(D)に設けられてドア開閉方向へ延びるレール部材(3)と、当該レール部材(3)に相対移動可能に設けられたスライダ(8)と、車両ボデー側から延びてスライダ(8)を経由してスライドドア(D)内の電気部品に至る給電線(54)とを具備する車両用スライドドアの給電構造において、スライダ(8)内に給電線(54)を挿通させるガイド孔(84)を形成し、当該ガイド孔(84)の両開口(841,842)のうち、車両ボデー側からの給電線(54)が入線する側に位置する開口(842)の、スライダ(8)のスライド方向に位置する開口内壁面(843,844)を、上記開口(842)が開放方向に向かって広がるように所定値以上の曲率半径でスライド方向へ湾曲するように形成し、ドア開閉に伴い給電線(54)が張力を受けたとき上記内壁面(843,844)に沿って湾曲するようにする。本第2発明では、スライドドア(D)に設けられてドア開閉方向へ延びるレール部材(3)と、当該レール部材(3)に相対移動可能に設けられたスライダ(8)と、車両ボデー側から延びてスライダ(3)を経由してスライドドア(D)内の電気部品に至る給電線(54)とを具備する車両用スライドドアの給電構造において、レール部材(3)はU字状をなしてその開口縁は内方へ向けて屈曲するフランジ部(31)となっており、スライダ(3)はブロック体で、その外側面にレール部材(3)のフランジ部に移動自在に嵌め込まれるスライド溝(871,872)が形成されるとともに、その内部に給電線(54)を挿通させるガイド孔(84)が形成され、ガイド孔(84)はスライダ(3)の一方の端部においてレール部材(3)内に開口しているとともにスライダ(3)の他方の端部においてレール部材(3)外に開口し、ガイド孔(84)の両開口(841,842)のうち、車両ボデー側からの給電線(54)が入線する側に位置する開口(842)の、スライダ(8)のスライド方向に位置する開口内壁面(843,844)が、開口(842)が開放方向に向かって広がるように所定値以上の曲率半径でスライド方向へ湾曲しており、ドア開閉に伴い給電線(54)が張力を受けたとき開口内壁面(843,844)に沿って湾曲するようにする。
【0008】
本発明においては、所定曲率半径以上でスライド方向へ湾曲する開口内壁面を有するガイド孔をスライダに形成してこれに給電線を挿通するようにしたから、スライドドアの開閉に伴い車両ボデー側から張力を受ける給電線は、ドアの閉鎖端あるいは開放端では上記開口内壁面の一方ないし他方に沿って湾曲させられる。この結果、給電線の曲りが過大な曲率になることはなく、これによって給電線の断線等が未然に防止される。本発明では、スライダにガイド部を設けることにより、従来のような金属製端子を使用することなく簡易な構造で給電線の断線等を防止することができる。
【0009】
【発明の実施の形態】
図1にはスライドドアに設けられたガイドレール3の縦断面図を示す。ガイドレール3の横断面は従来構造と同様に下方へ開放するU字状をなし、その開口縁は内方へ向けて略直角に屈曲するフランジ部31となっている。ガイドレール3の開口部にはこれに沿って移動自在にスライダ8が設けられており、その側面図を図2に、端面図を図3に示す。
【0010】
スライダ8はテフロン樹脂の略同形の厚肉板材81,82を重ね合わせて板面の二ヶ所でビス831,832により結合してブロック体としたものである。各板材81,82の衝合面には互いに対称形状に凹溝が形成され、板材を衝合すると上記凹溝によってスライダ8内を貫通する矩形断面のガイド孔84が形成される。ガイド孔84はスライダ8の一方の端面に開口(符号841)するとともに、スライダ8内で上方から下方へ緩やかに湾曲してスライダ8下面に開口(符号842)している。ガイド孔84の幅は側面視で湾曲の頂部付近までは一定であり、それ以降は下方へ向けてラッパ状に拡開している。このような形状のガイド孔84は、開口841から上方へ湾曲する際の曲率半径R1、上方から下方へ湾曲する際の曲率半径R2、開口842部が下方へ広がる際の左右の内壁面843,844の曲率半径R3,R4がいずれも所定値以上になっている。
【0011】
スライダ8のガイド孔開口842部には上方へ向かって漸次小径となる貫通孔85が両板材81,82の凹溝によって形成されて、スライダ8の端面に切り欠き形成された係止用凹所86に開口している。また、両板材81,82の外側面には同一位置に、下辺に沿って平行に延びる一定幅の矩形スライド溝871,872が形成されている。
【0012】
スライダ8は両側面のスライド溝871,872を図1に示すようにガイドレール3の開口縁フランジ部31に嵌め込んで移動自在としてある。そして、従来構造と同様にチューブ74内に通されて車両ボデー側から至った給電線54はスライダ8のガイド孔84内に挿通され、ガイドレール3内で上方へU字状に折り返されてガイドレール3の頂壁32下面に設けたコネクタ33に接続される。なお、ガイド孔84内への給電線54の挿通は、板材81,82を分離した状態で一方の板材81の凹溝内に給電線54を押し込み、これに他方の板材82を衝合することにより行なう。この時、給電線54は両板材81,82で挟持されて位置決めされる。金属ワイヤ71の一端は貫通孔85内に挿通され、その端部に取着された金属ボール711が係止用凹所86に係合する。車両ボデー側の給電構造は従来のものと同一である。
【0013】
このような構造において、スライドドアが開放状態と閉鎖状態の間で移動させられると、ガイドレール3が移動してもスライダ8は図4に示すようにその移動が制限される結果、ガイドレール3に対して相対移動し、ドア開放端ではスライダ8は図1、図4のX位置に、ドア閉鎖端ではスライダ8はY位置に至る。このようなスライダ8の移動に伴い、車両ボデー側からの張力によってX位置では給電線54はガイド孔開口842部のスライド方向の一方の内壁面843に沿って湾曲し、一方、Y位置では給電線54はガイド孔開口842部のスライド方向の他方の内壁面844に沿って湾曲する。ガイド孔84は既述のように、開口842部以外での湾曲の曲率半径および開口部内壁面843,844の曲率半径がいずれも所定値より大きくしてあるから、給電線54が張力を受けて湾曲しても過大な曲率で折れ曲がることはなく、給電線54の断線等が未然に防止される。このように本実施形態によれば、従来のような金属製端子73を使用することなく、スライダ8内にガイド孔84を形成してこれに給電線54を挿通させる簡易な構造でその断線等を防止することができる。
【0014】
【発明の効果】
以上のように、本発明の車両用スライドドアの給電構造によれば、簡易な構造で給電線の断線等を効果的に防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a power feeding structure for feeding power to a door glass lifting motor or the like of a vehicle sliding door.
[0002]
[Prior art]
In recent years, with the expansion of the use of van type vehicles as RV vehicles, it has become necessary to supply power from the vehicle body side to the door glass elevating motor and limit switch provided on the slide door in order to automate the elevating and lowering of the door glass. Yes. Accordingly, a power feeding structure as shown in FIGS. 5 and 6 has been proposed (for example, Japanese Patent Application Laid-Open No. 11-348683). Here, FIG. 5 is a lower vertical sectional view of the vehicle sliding door D in an opened state, and FIG. 6 is a horizontal sectional view thereof. An inner panel of the sliding door D is bent in an L shape (FIG. 5). A stay 1 projects toward the body panel P, and a roller bracket 12 is attached to the tip of the stay 1 via an auxiliary plate 11. ing. The roller bracket 12 is coupled to the auxiliary plate 11 so as to be rotatable in a horizontal plane, and horizontal rollers 13 and 14 are provided at the ends of the leg portions 121 and 122 (FIG. 6) which are divided into two branches in a plan view. Thus, these horizontal rollers 13 and 14 are located in the lower guide rail 21 provided on the lower surface of the step panel 2 (FIG. 5). The central portion of the roller bracket 12 is bent downward, and the vertical roller 15 is supported here and is positioned on the body panel P. When the sliding door D is closed, the sliding door D is guided by the guide rail 21, moves forward of the vehicle (right side in FIG. 6), and then is drawn inward (downward in FIG. 6).
[0003]
A guide rail 3 is provided on the inner panel of the slide door D in the door opening / closing direction. The guide rail 3 has a U-shaped cross section that opens downward (FIG. 5), and a slider 4 is provided at the opening thereof so as to be movable along the guide rail 3. A flat cable 41 extends from the front end of the slider 4 (the side facing the paper surface in FIG. 5). The flat cable 41 is folded upward in a U shape and reaches the rear end portion along the top wall of the guide rail 3. Input connection is made to the front end of the relay connector 42 provided here. A power supply line (not shown) extends from the rear end of the relay connector 42 to a door glass raising / lowering motor or the like in the slide door. A support member 7 is disposed between the slider 4 and the step panel 2. The support member 7 is formed by fixing metal terminals 72 and 73 having circular ring portions 721 and 731 to both ends of a flexible metal wire 71 that can be bent and deformed, and the circular ring portion 721 of the metal terminal 72 is attached to the support member 7. The circular ring portion 731 of the metal terminal 73 is rotatably fitted to the bolt 22 provided on the step panel 2 while being rotatably fitted to the bolt 61 provided on the slider 4. The power supply line 54 extending from the slider 4 to the vehicle body side is inserted into the tube 74 through the metal wire 71, crosses the vehicle body side, curves upward, passes through the step panel 2, and forms a wire harness (not shown). It is connected.
[0004]
In such a structure, when the slide door D moves from the open state to the closing direction in front of the vehicle, the slider 4 is pulled by the support member 7 even if the guide rail 3 moves forward (to the right in FIG. 6). As a result, the movement of the position is restricted, and the slider 4 moves relative to the guide rail 3. When the slide door D reaches the front end and is drawn to the closed position inside the vehicle, the support member 7 turns around the bolt 22 in the clockwise direction in FIG. In this case, the turning trajectory of the support member 7 and the movement trajectory of the slide door D do not necessarily coincide with each other, but the relative displacement between them is absorbed when the metal wire 71 of the support member 7 is appropriately curved and deformed.
[0005]
[Problems to be solved by the invention]
By the way, in the above-described conventional power feeding structure, the feeding wire 54 may be bent with a large curvature, particularly at the portion A in FIG. In this case, the power supply line 54 may be disconnected. Further, the power feeding structure has a problem that the metal terminal 72 and the mounting structure thereof are relatively complicated.
[0006]
Therefore, the present invention solves such a problem, and an object of the present invention is to provide a power supply structure for a sliding door for a vehicle that can prevent a power supply line from being disconnected with a simple structure.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, a rail member (3) provided on the slide door (D) and extending in the door opening / closing direction and a slider provided on the rail member (3) so as to be relatively movable. In a power supply structure for a vehicle slide door, comprising: (8) and a power supply line (54) extending from the vehicle body side and extending to the electrical component in the slide door (D) via the slider (8). 8) A guide hole (84) through which the feeder line (54) is inserted is formed in the inside of the opening (841, 842) of the guide hole (84), and the feeder line (54) from the vehicle body side is inserted. The curvature of the opening (842) positioned on the opening side is larger than a predetermined value so that the opening inner wall surface (843, 844) positioned in the sliding direction of the slider (8) extends in the opening direction. Sly in radius Formed to be curved in the direction, the feed line with the door (54) so as to bend along the inner wall surface (843 and 844) when subjected to tension. In the second invention, a rail member (3) provided on the slide door (D) and extending in the door opening / closing direction, a slider (8) provided on the rail member (3) so as to be relatively movable, and the vehicle body side In the power supply structure for a vehicle sliding door, the rail member (3) has a U-shape, and includes a power supply line (54) extending from the slider (3) to an electrical component in the slide door (D). The opening edge is a flange portion (31) that bends inward, and the slider (3) is a block body that is movably fitted to the flange portion of the rail member (3) on its outer surface. A slide groove (871, 872) is formed, and a guide hole (84) through which the feed line (54) is inserted is formed therein, and the guide hole (84) is a rail at one end of the slider (3). Member (3 The inside of the slider (3) and the other end of the slider (3) open to the outside of the rail member (3). Of the two openings (841, 842) of the guide hole (84), the feed line from the vehicle body side The opening inner wall surfaces (843, 844) positioned in the sliding direction of the slider (8) of the opening (842) positioned on the side where the line (54) enters are predetermined so that the opening (842) widens in the opening direction. It is curved in the sliding direction with a radius of curvature equal to or greater than the value, and is curved along the inner wall surface (843, 844) of the opening when the power supply line (54) receives tension as the door is opened and closed.
[0008]
In the present invention, since the guide hole having the inner wall surface of the opening that is curved in the sliding direction with a radius of curvature greater than or equal to the predetermined curvature radius is formed in the slider and the feed line is inserted through the guide hole, The feeding line receiving the tension is curved along one or the other of the inner walls of the opening at the closed end or the open end of the door. As a result, the bending of the feeder line does not have an excessive curvature, which prevents the feeder line from being disconnected. In the present invention, by providing the guide portion on the slider, it is possible to prevent disconnection of the feeder line with a simple structure without using a conventional metal terminal.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a longitudinal sectional view of a guide rail 3 provided on the slide door. The cross-section of the guide rail 3 has a U-shape that opens downward as in the conventional structure, and the opening edge is a flange portion 31 that bends in a substantially right angle toward the inside. A slider 8 is provided at the opening of the guide rail 3 so as to be movable along the opening. A side view thereof is shown in FIG. 2, and an end view thereof is shown in FIG.
[0010]
The slider 8 is a block body in which thick plate materials 81 and 82 of substantially the same shape made of Teflon resin are overlapped and coupled with screws 831 and 832 at two locations on the plate surface. Concave grooves are formed symmetrically on the abutting surfaces of the plate members 81 and 82. When the plate members are abutted with each other, a guide hole 84 having a rectangular cross section penetrating the slider 8 is formed by the concave groove. The guide hole 84 opens at one end face of the slider 8 (reference numeral 841), and gently curves from the upper side to the lower side within the slider 8 and opens at the lower surface of the slider 8 (reference numeral 842). The width of the guide hole 84 is constant up to the vicinity of the top of the curve in a side view, and thereafter, the guide hole 84 is expanded in a trumpet shape downward. The guide hole 84 having such a shape has a curvature radius R1 when bending upward from the opening 841, a curvature radius R2 when bending downward from above, and left and right inner wall surfaces 843 when the opening 842 portion expands downward. The curvature radii R3 and R4 of 844 are both equal to or greater than a predetermined value.
[0011]
In the guide hole opening 842 of the slider 8, a through hole 85 having a gradually decreasing diameter is formed by the concave grooves of both plate members 81, 82, and the locking recess is formed by cutting out the end surface of the slider 8. 86 is open. In addition, rectangular slide grooves 871 and 872 having a constant width extending in parallel along the lower side are formed at the same position on the outer surfaces of both plate members 81 and 82.
[0012]
As shown in FIG. 1, the slider 8 is configured to be movable by fitting the slide grooves 871 and 872 on both sides into the opening edge flange portion 31 of the guide rail 3. As in the conventional structure, the power supply line 54 that is passed through the tube 74 and reaches from the vehicle body side is inserted into the guide hole 84 of the slider 8 and is folded back upward in the guide rail 3 into a U shape. It is connected to a connector 33 provided on the lower surface of the top wall 32 of the rail 3. In order to insert the power supply line 54 into the guide hole 84, the power supply line 54 is pushed into the concave groove of one plate 81 with the plate 81, 82 separated, and the other plate 82 is brought into contact with this. To do. At this time, the feeder 54 is positioned by being sandwiched between the two plate members 81 and 82. One end of the metal wire 71 is inserted into the through hole 85, and the metal ball 711 attached to the end engages with the locking recess 86. The power supply structure on the vehicle body side is the same as the conventional one.
[0013]
In such a structure, when the slide door is moved between the open state and the closed state, even if the guide rail 3 moves, the slider 8 is restricted from moving as shown in FIG. The slider 8 reaches the X position in FIGS. 1 and 4 at the door open end, and the slider 8 reaches the Y position at the door closed end. With such movement of the slider 8, the feed line 54 is curved along one inner wall surface 843 in the sliding direction of the guide hole opening 842 portion at the X position due to the tension from the vehicle body side, while at the Y position, the supply line 54 is fed. The electric wire 54 is curved along the other inner wall surface 844 in the sliding direction of the guide hole opening 842 portion. As described above, the curvature radius of the guide hole 84 other than the opening 842 and the curvature radius of the inner wall surfaces 843 and 844 of the opening are both larger than a predetermined value. Even if it is bent, it is not bent with an excessive curvature, and disconnection of the power supply line 54 is prevented in advance. As described above, according to the present embodiment, without using the conventional metal terminal 73, the guide hole 84 is formed in the slider 8, and the power supply line 54 is inserted through the guide hole 84. Can be prevented.
[0014]
