Description

  The present invention relates to a power supply device that is mounted on an automobile and that supplies power and transmits signals from a vehicle body to electrical components of a slide door.

  2. Description of the Related Art Conventionally, a vehicle provided with a slide door is equipped with a power supply device that supplies power and transmits signals from a vehicle body to electrical components of the slide door. FIG. 8 is an explanatory diagram illustrating a locus of a wire harness in a conventional power supply device (see, for example, Patent Documents 1 and 2).

  The power supply device 401 illustrated in FIG. 8 includes a wire harness 404 that is routed from a vehicle main body to a slide door, a main unit 402, and a door unit 403. The body-side unit 402 supports the corrugated tube 51, which is an exterior member of the wire harness 404, so as to be rotatable around the axis P1 on the vehicle body side. The door-side unit 403 supports the corrugated tube 51 so as to be rotatable around the axis P2 on the slide door side. Arrow X in FIG. 8 is parallel to the width direction of the vehicle, arrow Y is parallel to the front-back direction of the vehicle, and arrow Z is parallel to the up-down direction of the vehicle.

  In FIG. 8, reference numeral 403A is assigned to the door-side unit when the slide door is fully closed, and reference numeral 404A is assigned to the wire harness when the slide door is fully closed. Further, the reference numeral 403B is assigned to the door side unit when the sliding door starts to open, and the reference numeral 404B is assigned to the wire harness when the sliding door starts to open. The door-side unit when the sliding door is half-open is denoted by reference numeral 403C, and the wire harness when the slide door is half-opened is denoted by reference numeral 404C. Also, the reference numeral 403D is assigned to the door side unit when the sliding door is fully opened, and the reference numeral 404D is assigned to the wire harness when the sliding door is fully opened.

  In such a power supply device 401, there is a problem that the wire harness 404 curved by opening and closing the slide door is suppressed from expanding toward the vehicle body. This is because, when the wire harness 404 expands toward the vehicle body, the wire harness 404 easily interferes with the vehicle body or has a poor appearance. In order to solve this problem, in the power supply device 401, a bending restricting member is inserted into the corrugated tube 51, and a spring is incorporated in the main unit 402 and the door unit 403. As a result, as shown in FIG. 8, in the wire harness 404C when the slide door is half-opened, a portion near the main unit 402 extends in the vehicle front-rear direction, and swelling toward the vehicle main body is suppressed.

  As described above, in the conventional power supply device 401, the swelling of the wire harness 404C toward the vehicle body when the slide door is half-opened can be suppressed. However, the swelling of the wire harness 404B when opening the sliding door (the portion G in FIG. 8) has not been sufficiently suppressed, and there is room for improvement.

  Therefore, an object of the present invention is to provide a power supply device that can prevent the wire harness from expanding toward the vehicle body when the slide door starts opening.

  In order to solve the above problem, a power supply device of the present invention includes an electric wire and an exterior member covering an outer periphery of the electric wire, and a wire harness routed from a vehicle body of an automobile to a slide door; A vehicle-side unit that rotatably supports the vehicle body side; and a door-side unit that rotatably supports the exterior member on the slide door side, wherein the door-side unit is provided with respect to the slide door. A first door rotor rotatable about a first axis; and a second door rotor rotatably connected to the first door rotor about a second axis parallel to the first axis. The second door rotor is attached to an end of the exterior member, and the electric wire coming out of the end of the exterior member passes through the inside of the second door rotor, and further passes through the inside of the first door rotor. Said Characterized in that it is routed to Idodoa side.

  According to the present invention, the door-side unit has a first door rotor rotatable around a first axis with respect to the slide door, and a second door parallel to the first axis with the first door rotor. A second door rotor rotatably connected about an axis, wherein the second door rotor is attached to an end of the exterior member, and the electric wire coming out of the end of the exterior member is the second door rotor. It is passed through the inside of the door rotor and further passed through the inside of the first door rotor and is routed to the slide door side. Thus, when the slide door starts to open, the portion near the slide door in the wire harness can be curved with a smaller radius of curvature than the conventional product. Therefore, it is possible to prevent the wire harness from expanding toward the vehicle body when the slide door starts to open.

That is, at the connection point between the first door rotor 8 and the second door rotor 9, a height difference H is provided in the wiring harness routing path. As a result, the electric wire 7 positioned at the connection location is not bent but twisted when the first door rotor 8 and the second door rotor 9 rotate.

  As shown in FIG. 1, the power supply device 1 having the above configuration can bend the portion of the wire harness 4 near the slide door with a smaller radius of curvature than the conventional product when the slide door starts to be opened. Swelling toward the vehicle body can be suppressed. Thereby, interference between the wire harness 4 and the vehicle body can be prevented, and a deterioration in appearance due to the swelling of the wire harness 4 can be avoided.

  In the power supply device 1, as shown in FIGS. 5 and 6, the contact portion 94 of the second door rotor 9 contacts the side surface of the main body portion 81 of the first door rotor 8 from when the slide door is fully closed to when the slide door starts to open. Thus, the rotation angles of the first door rotor 8 and the second door rotor 9 are limited. Accordingly, the radius of curvature of the wire harness 4 in the vicinity of the slide door is restricted from being excessively small, and disconnection of the electric wire 7 is suppressed. The contact portion 94 may be provided on the first door rotor 8 side instead of being provided on the second door rotor 9 side.

  Although the door-side unit 3 of the above-described embodiment includes the door protector 32 to which the first door rotor 8 is rotatably attached, the door protector 32 is not an essential component in the present invention. That is, in the present invention, the first door rotor 8 may be provided so as to be rotatable about the first axis P2 with respect to the slide door. Further, the wire harness 4 of the above-described embodiment includes the bending restriction member 6, but in the present invention, the wire harness may not necessarily include the bending restriction member 6.

  Note that the above-described embodiment merely shows a typical mode of the present invention, and the present invention is not limited to this embodiment. That is, various modifications can be made without departing from the gist of the present invention. As long as the configuration of the present invention is still provided by such a modification, it is, of course, included in the scope of the present invention.
