[0015] Hereinafter, embodiments of the slide door power feeding device according to the present invention will be described with reference to the drawings. The present invention is not limited to these embodiments. The present invention is applicable to general slide door power feeding devices.

[0016] In addition, in the description of the drawings, the same or corresponding elements are denoted by the same reference numerals as appropriate. It should also be noted that the drawings are schematic, and the dimensional relationships and proportions of elements may differ from actual conditions. Even between the drawings, there may be portions where the dimensional relationships and proportions differ from one another.

[0017] (Embodiment) Structure of Slide Door Power Feeding Device Figure 1 is a schematic diagram of the configuration of a sliding door power supply device according to an embodiment. As shown in Figure 1, the sliding door power supply device 1 according to this embodiment comprises a body-side rotating support 2, a door-side rotating support 3, a wire bundle 4, and a grommet 5. The sliding door power supply device 1 holds the wire bundle 4 that electrically connects the vehicle body and the sliding door.

[0018] Figure 2 is an exploded view of the sliding door power supply device shown in Figure 1. As shown in Figure 2, the sliding door power supply device 1 comprises a body-side rotating body 6 and a door-side rotating body 7.

[0019] The body-side rotating support 2 consists of a first part 21 and a second part 22 that fit together with each other.

[0020] The door-side rotating support 3 consists of a first part 31 and a second part 32 that fit together with each other.

[0021] The wire bundle 4 is a power supply harness made up of multiple insulated wires bundled together. A grommet 5 is attached to the wire bundle 4 to protect it, and it is stretched between the vehicle body and the sliding door. At the base end (vehicle body side) and the tip end (sliding door side) of the wire bundle 4, a base-side connector (not shown) and a tip-side connector (not shown) are attached, respectively, to accommodate terminal fittings crimped to each insulated wire. The wire bundle 4 may also include various wirings such as communication lines in addition to insulated wires. The base-side connector is connected to a floor-side connector attached to the end of the vehicle body-side harness, which is a wire harness routed on the floor panel. In this way, the vehicle body-side harness and the wire bundle 4 are electrically connected. The vehicle body-side harness and the wire bundle 4 may not have floor-side connectors and base-side connectors respectively, and the vehicle body-side harness and the power supply harness may be configured as a single continuous wire harness.

[0022] The body-side rotating body 6 consists of a first part 61 and a second part 62 that fit together with each other.

[0023] The door-side rotating body 7 consists of a first part 71 and a second part 72 that fit together with each other.

[0024] [Installation status of the sliding door power supply device] Figure 3 shows the sliding door power supply device shown in Figure 1 installed on the vehicle and the sliding door. Figure 3 shows the sliding door power supply device 1 in the fully closed position. As shown in Figure 3, the grommet 5 of the sliding door power supply device 1 is located between the door trim 11 and the scuff plate 12, and the grommet 5 is hidden by the scuff plate 12, so it is not visible to passengers seated in the seats.

[0025] Figure 4 shows the door trim and scuff plate removed from Figure 3. As shown in Figure 4, the sliding door power supply device 1 is attached to the vehicle body on the vehicle body side by a body-side rotating support 2, and attached to the sliding door on the sliding door side by a door-side rotating support 3.

[0026] [Overview of the operation of the sliding door power supply device when the door is opened and closed] Figures 5 to 7 show the operation of the sliding door power supply device when the door is opened and closed, viewed from above, from the outside of the vehicle, and from the front, respectively. Figures 5 to 7 illustrate the sliding door power supply device 1 when the door is fully open (A), half-open (B), and fully closed (C).

[0027] As shown in Figure 5, the sliding door power supply device 1 and the fender panel 13 are positioned so as not to interfere with each other when the door is opened or closed. Also, as shown in Figure 7, the door-side rotating support 3 is mounted above the body-side rotating support 2. As a result, the central part of the grommet 5 flexes due to gravity and moves below the door trim 11, preventing interference between the sliding door power supply device 1 and the door trim 11.

[0028] [Detailed configuration of each part of the vehicle body] Figure 8 is an enlarged view of the body-side rotating support. Figure 8 is a view of the body-side rotating support 2 from above. The body-side rotating support 2 is attached to the vehicle body and holds the wire bundle 4 at a first angle θ1 from the front of the vehicle (right side in Figure 8) to the outside of the vehicle (top of Figure 8). The first angle θ1 is, for example, 45°, but may be any angle in the range of 30° to 60°.

[0029] Figure 9 is an enlarged view of the body-side rotating body. Figure 9 is a view of the body-side rotating body 6 from above, showing the state after removing the second part 22 from Figure 8. The body-side rotating body 6 is pivotably supported by the body-side rotating support 2 and rotates in accordance with the opening and closing operation of the sliding door. The body-side rotating body 6 has a cylindrical body-side inner cylinder portion 6a that holds the wire bundle 4 at a first angle θ1, and a body-side inclined inner cylinder portion 6b that extends from the body-side inner cylinder portion 6a toward the sliding door and holds the wire bundle 4 at a second angle θ2 relative to the body-side inner cylinder portion 6a. The second angle θ2 is, for example, 45°, but may be any angle in the range of 30° to 60°.

[0030] Figures 10 to 12 show the positions of the body-side rotating body when the door is fully open, half-open, and fully closed, respectively. The body-side rotating support 2 restricts the rotation of the body-side rotating body 6 to 90° forward and backward from the position where the body-side inclined inner cylinder portion 6b faces furthest downward (the state in Figure 11) (the state in Figures 10 and 12). That is, in the state in Figure 10, the body-side rotating body 6 can only rotate in the counterclockwise direction indicated by the arrow, and in the state in Figure 12, the body-side rotating body 6 can only rotate in the clockwise direction indicated by the arrow. Specifically, the rotation of the body-side rotating body 6 is restricted by the contact between a recess or protrusion formed inside the body-side rotating support 2 and a protrusion or recess protruding from the outside of the body-side rotating body 6.

[0031] [Detailed configuration of each part on the sliding door side] Figure 13 is an enlarged view of the door-side rotating support. Figure 13 is a view of the door-side rotating support 3 from the front. The door-side rotating support 3 is attached to the sliding door side and holds the wire bundle 4 at a third angle θ3 from below the vehicle (bottom of Figure 13) towards the inside of the vehicle (right side of Figure 13). The third angle θ3 is, for example, 45°, but may be any angle in the range of 30° to 60°.

[0032] Figure 14 is an enlarged view of the door-side rotating body. Figure 14 is a view of the door-side rotating body 7 from the direction of arrow Ar in Figure 13. The door-side rotating body 7 is pivotably supported on the door-side rotating support 3 and rotates in accordance with the opening and closing operation of the sliding door. The door-side rotating body 7 has a cylindrical door-side inner cylinder portion 7a that holds the wire bundle 4 at a third angle θ3, and a door-side inclined inner cylinder portion 7b that extends from the door-side inner cylinder portion 7a toward the vehicle body and holds the wire bundle 4 at a fourth angle θ4 relative to the door-side inner cylinder portion 7a. The fourth angle θ4 is, for example, 45°, but may be any angle in the range of 30° to 60°.

[0033] Figures 15 to 17 show the positions of the door-side rotating body when the door is fully open, half-open, and fully closed, respectively. The door-side rotating support 3 restricts the rotation of the door-side rotating body 7 to 90° forward and backward from the position where the door-side inclined inner cylinder portion 7b faces furthest downward (the state in Figure 16) (the state in Figures 15 and 17). That is, in the state in Figure 15, the door-side rotating body 7 can only rotate in the clockwise direction indicated by the arrow, and in the state in Figure 17, the door-side rotating body 7 can only rotate in the counterclockwise direction indicated by the arrow. Specifically, the rotation of the door-side rotating body 7 is restricted by the contact between a recess or protrusion formed inside the door-side rotating support 3 and a protrusion or recess protruding from the outside of the door-side rotating body 7.

[0034] As described above, the sliding door power supply device 1 according to this embodiment has a simple configuration that does not require a case, springs, or other components. Furthermore, since the grommet 5 of the sliding door power supply device 1 is hidden by the scuff plate 12, it is not visible to passengers seated in the seats. Moreover, the movement of the grommet 5 of the sliding door power supply device 1 is restricted by the body-side rotating body 6 and the door-side rotating body 7, and the movement of the body-side rotating body 6 and the door-side rotating body 7 is restricted by the body-side rotating support 2 and the door-side rotating support 3 at a first angle θ1 to a fourth angle θ4, so that the grommet 5 does not interfere with the door trim 11 or fender panel 13 when the door is opened or closed.

[0035] Further effects and modifications can be readily derived by those skilled in the art. Therefore, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents.
