[0002]

2. Description of the Related Art FIGS. 5 and 6 show an example of a constant power feeding type slide door power feeding structure. A rotary clamp 1'is provided on the step panel P1 (FIG. 6) on the vehicle body side,
The power supply line (wire harness) 2 is bridged to the slide door D side through the rotary 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 in the outer case 11 so as to be relatively rotatable, and the wire harness 2 is inserted therethrough. One end 3 of a flexible corrugated tube 3 formed in a bellows shape
One outer circumference is held by the inner cylinder 12.

On the other hand, a power feeding case 4'is provided on the inner surface of the slide door D. The power feeding case 4'is a case body having a substantially U-shaped cross section that opens downward, and its front view has a mountain shape (Fig. 5), and an opening 41 (Fig. 5) at the lower end that extends in the door sliding direction (left and right direction in Fig. 5). 6). When the slide door D is closed, the corrugated tube 3 which has passed through the rotary clamp 1'to the side of the slide door D, as shown in FIG.
The wire harness 2 taken out from the sliding door D is pulled into the ‘′’ and extends inside along the chevron top 42. The other end 32 of the corrugated tube 3 is fixed to the end of the power feeding case 4 ′. It extends to each device in.

When the sliding door D is opened from the closed position, the power feeding case 4 integrated with the door D moves to the right from the position shown in FIG. 5 and is opposite to the rotary clamp 1'as shown in FIG. Move to. Along with this, the corrugated tube 3 is pulled out of the power feeding case 4 ′ and is fed to the power feeding case 4 ′.

[0005]

By the way, in such a power feeding structure, when the slide door D is close to the fully closed position, the corrugated tube 3 extending from the rotary clamp 1 ', as shown in FIG. Upper door trim DT
Since there is a small gap between the seal member S provided on the lower edge and the scuff plate P2 (FIG. 6) to secure liquid tightness, there is a problem in that manufacture and assembly are difficult so as not to interfere with each other. Further, when the slide door D is almost fully opened, the door arm DA is provided directly below the corrugated tube 3 extending from the rotary clamp as shown in FIG.
However, since the gap between the door arm DA and the corrugated tube 3 is small, there is a problem in that manufacturing and assembling are difficult so that the two do not interfere with each other.

Therefore, the present invention solves such a problem by making it possible to sufficiently secure a gap between the power supply line and other members such as a seal member and a door arm with a simple structure, thereby facilitating interference between the two. An object of the present invention is to provide a power supply structure for a slide door that can be avoided.

[0007]

To achieve the above object, in the first aspect of the present invention, a sliding door (D) is passed from a vehicle body (P1) side through a rotary clamp (1) provided on the vehicle body (P1). In a power supply structure of a slide door in which the power supply lines (2, 3) are bridged to the side, a power supply line is provided by an inner cylinder (12) installed in a substantially horizontal posture and supported in a relatively rotatable manner in an outer case (11). Holding the outer periphery of (2, 3), the power supply line (2, 3) along with the opening and closing movement of the slide door (D)
The opening of the inner cylinder (12) of the rotary clamp (1) where the inner cylinder (12) rotates so as to eliminate the twist of the inner cylinder (12) on the side where the power supply lines (2, 3) are directed toward the slide door (D). Is provided with a tubular guide portion (13) that passes through the power supply lines (2, 3) and is inclined with respect to the axis line (L) of the inner cylinder (12). Shake (2, 3) vertically.

In the first aspect of the present invention, if the inner cylinder is set to rotate so that the guide portion faces downward when the slide door is near the fully closed position, the inner cylinder extends from the guide portion. Since the power feed line is swung downward, a sufficient gap is secured with the seal member provided on the lower edge of the upper door trim, and even if there is some manufacturing and assembly error, the two do not interfere with each other. When the slide door is slid to the fully open position, the inner cylinder is rotated about 180 degrees, and the guide portion thereof faces upward. As a result, the power supply line extending from the guide portion is swung upward, and even if the door arm reaches directly below it, a sufficient gap is secured between the door arm and the corrugated tube. There is no interference between the two.

In the second aspect of the present invention, the power supply lines (2, 3) are bridged from the vehicle body (P1) side to the slide door (D) side through the power supply case (4) provided in the slide door (D). In the power supply structure for the slide door, the slide door (D) has an opening (41) having a substantially U-shaped cross section that opens downward and extending in the door sliding direction of the slide door (D). , 3) are drawn in and the power supply line (2, 3) is moved relative to the door slide direction while being in contact with the side wall lower end (411) on the side closer to the vehicle body (P1) as the slide door (D) is opened and closed. The side wall lower end (411) of the power supply case (4) is tilted in the door sliding direction.

In the second aspect of the present invention, when the slide door is near the fully closed position, it is necessary to set the power supply line so that it can be drawn into the power supply case while contacting the lower end of the side wall at the relatively low position. The position of the power supply line extending to the slide door side can be kept low as a whole. As a result, a sufficient gap is secured with the seal member provided on the lower edge of the upper door trim, and even if there is some manufacturing and assembly error, the two do not interfere with each other. 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. Therefore, the position of the power supply line extending to the slide door side becomes high as a whole, and even if the door arm reaches directly below it, a sufficient gap is secured between the door arm and the power supply line. As a result, there is no interference between the two even if there is some manufacturing and assembly error.

The reference numerals in the parentheses indicate the correspondence with the concrete means described in the embodiments described later.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIGS. 1 and 2 show an example of a rotary clamp used in a slide door power feeding structure of the present invention. In FIG. 1, an inner case 12 (FIG. 2) is rotatably supported and housed in an outer case 11 of a rotary clamp 1, and a wire harness 2 as a power supply line is housed in the inner case 12 so as to be housed therein. The corrugated tube 3 extends toward the slide door D (FIG. 6). And
The opening of the inner cylinder 12 on the side where the corrugated tube 3 exits is a cylindrical guide portion 13 as shown in FIG. 2, and the guide portion 13 is bent so as to be inclined with respect to the axis L of the inner cylinder 12. The corrugated tube 3 that faces the slide door D passes through the inside thereof.

In the rotary clamp 1 having such a structure, when the slide door D is in the closed position (that is,
When the power feed case 4 is located on the left side of the rotary clamp 1 as shown in FIG. 5, the inner cylinder 12 is rotated so that the guide portion 13 faces downward as shown in FIG. ing. As a result, the corrugated tube 3 extending from the guide portion 13 is swung downward, and therefore, the seal member S provided at the lower edge of the upper door trim DT (FIG. 9).
A sufficient gap is secured between the two and even if there is some manufacturing and assembly error, they do not interfere with each other.

When the slide door D is slid to the open position (that is, when the power feeding case 4 is moved to the right side with respect to the rotary clamp 1 as shown in FIG. 8), the inner cylinder 12 is correspondingly moved to about 180. The guide part 13 is rotated once
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 directly below the corrugated tube 3, a sufficient gap between the door arm DA and the corrugated tube 3 is secured, and the corrugated tube 3 is manufactured to some extent. Even if there is an error in the assembly, the two do not interfere with each other.

(Second Embodiment) FIG. 4 shows an example of a power feeding case 4 used in the sliding door power feeding structure of the present invention.
In FIG. 4, the power feeding case 4 has a side wall lower end 411 near the vehicle body, which forms an opening 41 into which the corrugated tube 3 extending from the rotary clamp 1 is drawn, and is located at the front side in the door sliding direction (left side in FIG. 4). It is tilted up toward. Here, when the slide door D is slid from the closed position to the open position, the corrugated tube 3
Is the lower end 41 of the side wall of the power supply case 4 on the side closer to the vehicle body.
While being in contact with 1, the retracted position moves along the opening 41 as shown by the broken line in FIG.

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 side wall lower end 411 at the relatively lower position. The position of the corrugated tube 3 extending from the rotary clamp 1 to the side of the sliding door D is kept low as a whole. As a result, a sufficient gap is secured with the seal member S provided at the lower edge of the upper door trim DT (FIG. 9), and even if there is some manufacturing and assembly error, they do not interfere with each other.

When the slide door D slides near 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 located at a relatively high position. It is drawn into the power feeding case 4. Therefore, the position of the corrugated tube 3 extending from the rotary clamp 1 to the side of the slide door D becomes high as a whole, and the door arm DA (see FIG.
Even when 0) is reached, a sufficient gap is secured between the door arm DA and the corrugated tube 3. As a result, there is no interference between the two even if there is some manufacturing and assembly error.

In the above embodiment, an example in which the wire harness is inserted into the corrugated tube and bridged from the vehicle body side to the slide door side has been described. However, even when the wire harness is directly bridged without using the corrugated tube. Of course, the invention can be applied.

[0019]

As described above, according to the power supply structure for a 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, so that the two interfere with each other. Can be avoided easily and surely.
