BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply structure for a sliding door. It relates to the improvement of the feeding structure.
[0002]
[Prior art]
FIG. 5 and FIG. 6 show an example of a constantly feeding type sliding door feeding structure. A rotation clamp 1 ′ is provided on a step panel P 1 (FIG. 6) on the vehicle body side, and a power supply line (wire harness) 2 is bridged to the slide door D side through the rotation clamp 1 ′. The rotary clamp 1 has a known structure including an outer case 11 shown in FIG. 7 and an inner cylinder 12 (FIG. 6) supported so as to be relatively rotatable in the outer case 11, and the wire harness 2 is inserted therethrough. The outer periphery of one end 31 of the flexible corrugated tube 3 formed in a bellows shape is held by the inner cylinder 12.
[0003]
On the other hand, a power supply case 4 ′ is provided on the inner side surface of the slide door D. The power supply case 4 ′ is a case body having a substantially U-shaped cross section that opens downward, and has a mountain shape when viewed from the front (FIG. 5), and an opening 41 that extends in the door slide direction (left-right direction in FIG. 5) at the lower end. 6). As shown in FIG. 5, the corrugated tube 3 that has passed through the rotary clamp 1 ′ and crossed to the slide door D side is drawn into the power supply case 4 ′ from one end side of the opening 41 as shown in FIG. 5. The other end 32 of the corrugated tube 3 is fixed to the end of the power supply case 4 ′, and the wire harness 2 taken out from this extends to each device in the slide door D. ing.
[0004]
When the sliding door D is opened from the closed position, the power supply case 4 integrated with the door D moves to the right from the position shown in FIG. 5, and moves to the opposite side as shown in FIG. Along with this, the corrugated tube 3 is pulled out of the power supply case 4 ′ and the drawing position into the power supply case 4 ′ moves from one end side to the other end side of the opening 41, and the chevron 42 of the power supply case 4 ′. The posture is along the outer periphery of the guide wall 43 that is curved with a small radius of curvature away from the inner side. During this time, the inner cylinder 12 (FIG. 6) of the rotary clamp 1 ′ rotates about 180 degrees so as to eliminate the twist of the corrugated tube 3.
[0005]
[Problems to be solved by the invention]
By the way, in such a power feeding structure, when the slide door D is close to the fully closed position, as shown in FIG. 9, the corrugated tube 3 extending from the rotary clamp 1 ′ and the lower edge of the door trim DT above the corrugated tube 3 are provided. In addition, since the gap between the scuff plate P2 (FIG. 6) and the seal member S that secures liquid-tightness is small, there is a problem in that it is difficult to manufacture and assemble so that they do not interfere with each other. Further, in the state where the slide door D is almost fully open, the door arm DA reaches just below the corrugated tube 3 extending from the rotary clamp as shown in FIG. 10, and the gap between the door arm DA and the corrugated tube 3 is small in this case. However, there was a problem that it was difficult to make and assemble so that they did not interfere with each other.
[0006]
Therefore, the present invention solves such a problem, and it is possible to easily avoid the interference between the power supply line and other members such as a seal member and a door arm with a simple structure. An object of the present invention is to provide a sliding door feeding structure.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the power supply line (2, 3) from the vehicle body (P1) side to the slide door (D) side through the rotary clamp (1) provided on the vehicle body (P1). In the power supply structure of the sliding door that spans the power supply line (2, 3) is held by the inner cylinder (12) that is installed in a substantially horizontal posture and is supported so as to be relatively rotatable in the outer case (11). The rotating clamp (1) in which the inner cylinder (12) rotates so as to eliminate the twist of the power supply lines (2, 3) with the opening and closing movement of the sliding door (D) is directed toward the sliding door (D). A cylindrical guide that passes through the feed line (2, 3) through the opening of the inner cylinder (12) on the side from which the feed line (2, 3) exits and is inclined with respect to the axis (L) of the inner cylinder (12) The part (13) is provided, and the feed lines (2, 3) are moved up and down as the inner cylinder (12) rotates. So that shake to.
[0008]
In the first aspect of the present invention, when the sliding door is near the fully closed position, if the inner cylinder is set to rotate to a position where the guide portion faces downward, the power supply line extending from the guide portion is Since it is swung downward, a sufficient gap with the seal member provided at the lower edge of the upper door trim is ensured, and even if there is a certain amount of manufacturing and assembly errors, there is no interference between the two. When the sliding door is slid and moved to the fully open position, the inner cylinder is rotated about 180 degrees along with this, and the guide portion faces upward. As a result, the power supply line extending from the guide portion is swung upward, and even if the door arm reaches just below it, a sufficient gap is secured between the door arm and the corrugated tube. There is no interference between the two.
[0009]
According to the second aspect of the invention, the sliding door is configured such that the feeding lines (2, 3) are bridged from the vehicle body (P1) side to the sliding door (D) side through the feeding case (4) provided on the sliding door (D). The power feeding structure has an open port (41) that has a substantially U-shaped cross section that opens downward, and extends in the door sliding direction of the slide door (D), and the feed line (2, 3) from the open port (41). Power supply case in which the power supply lines (2, 3) are relatively moved in the sliding direction of the door while being in contact with the lower end (411) of the side wall close to the vehicle body (P1) as the sliding door (D) is opened and closed. The side wall lower end (411) of (4) is inclined in the door sliding direction.
[0010]
In the second aspect of the invention, when the sliding door is close to the fully closed position, the sliding door is set so that the feeding line can be drawn into the feeding case while contacting the lower end of the side wall at a relatively low position. The position of the feeder line extending to the side is kept low as a whole. As a result, a sufficient gap with the seal member provided at the lower edge of the upper door trim is ensured, and even if there is a certain amount of manufacturing and assembly errors, there is no interference between the two. When the sliding door slides to the fully open position, the corrugated tube moves in the opening and comes into contact with the lower end of the side wall at a relatively high position, and is drawn into the power supply case from here. Accordingly, the position of the power supply line extending toward the slide door becomes high as a whole, and even if the door arm reaches just below it, a sufficient gap is secured between the door arm and the power supply line. Thereby, even if there is a certain amount of manufacturing and assembly error, there is no interference between the two.

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
1 and 2 show an example of a rotary clamp used in the sliding door power feeding structure of the present invention. In FIG. 1, an inner cylinder 12 (FIG. 2) is supported and accommodated in an outer case 11 of the rotary clamp 1 so as to be relatively rotatable, and a wire harness 2 serving as a power supply line is accommodated by being held by the inner cylinder 12. The corrugated tube 3 extends toward the slide door D (FIG. 6). And the opening part of the inner cylinder 12 in the side where the corrugated tube 3 exits becomes a cylindrical guide part 13 as shown in FIG. 2, and the guide part 13 is inclined with respect to the axis L of the inner cylinder 12. The corrugated tube 3 that is bent and passes toward the slide door D passes through the inside thereof.
[0013]
In the rotary clamp 1 having such a structure, when the slide door D is in the closed position (that is, when the power supply case 4 is positioned on the left side as shown in FIG. 5), FIG. As shown in FIG. 2, the inner cylinder 12 is rotated to a position where the guide portion 13 faces downward. As a result, the corrugated tube 3 extending from the guide portion 13 is swung downward, so that a sufficient clearance from the seal member S provided at the lower edge of the upper door trim DT (FIG. 9) is ensured to some extent. Even if there is an assembly error, there is no interference between the two.
[0014]
When the sliding door D is slid to the open position (that is, when the power supply case 4 is moved to the right as shown in FIG. 8 with respect to the rotary clamp 1), the inner cylinder 12 rotates about 180 degrees accordingly. The guide portion 13 faces upward as shown in FIG. As a result, the corrugated tube 3 extending from the guide portion 13 is swung upward, so that even if the door arm DA (FIG. 10) reaches immediately below, the gap between the door arm DA and the corrugated tube 3 is sufficiently secured, and a certain amount of manufacturing is performed. Even if there is an assembly error, there is no interference between the two.
[0015]
(Second Embodiment)
FIG. 4 shows an example of the power supply case 4 used in the sliding door power supply structure of the present invention. 4, the power supply case 4 forms an opening 41 into which the corrugated tube 3 extending from the rotary clamp 1 is drawn, and the side wall lower end 411 on the side close to the vehicle body is in front of the door slide direction (left side in FIG. 4). It is tilted up toward. Here, when the sliding door D is slid from the closed position to the open position, the corrugated tube 3 is in contact with the side wall lower end 411 on the side close to the vehicle body of the power supply case 4, and the drawing position is as described above. It moves along the opening 41 from the broken line in FIG.
[0016]
At this time, when the slide door D is near the fully closed position, the corrugated tube 3 is drawn into the power supply case 4 while being in contact with the one end portion 412 of the lower end 411 of the side wall at a relatively low position. The position of the corrugated tube 3 extending to the slide door D side is kept low as a whole. As a result, a sufficient gap with the seal member S provided at the lower edge of the upper door trim DT (FIG. 9) is ensured, and even if there is a certain amount of manufacturing and assembly errors, there is no interference between the two.
[0017]
When the sliding door D is slid and moved close to the fully open position, the corrugated tube 3 moves in the opening 41 and comes into contact with the other end 413 of the side wall lower end 411 at a relatively high position. It is drawn in. Therefore, the position of the corrugated tube 3 extending from the rotary clamp 1 to the slide door D side as a whole becomes high, and even if the door arm DA (FIG. 10) reaches just below, the gap between the door arm DA and the corrugated tube 3 is sufficiently secured. . Thereby, even if there is a certain amount of manufacturing and assembly error, there is no interference between the two.
[0018]
In the above embodiment, the example in which the wire harness is inserted into the corrugated tube and is bridged from the vehicle body side to the slide door side has been described. However, the present invention is also applied to the case where the wire harness is directly bridged without using the corrugated tube. Of course you can.
[0019]
【The invention's effect】
As described above, according to the power supply structure for the sliding door of the present invention, the gap between the power supply line and the other members such as the seal member and the door arm can be sufficiently secured with a simple structure. It can be avoided.
