[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The wire harness in this disclosure is [1] A wire harness comprising a group of electric wires routed from a vehicle body to a sliding door that can be opened and closed relative to the vehicle body, wherein the harness comprises a lighting member extending along the direction of extension of the group of electric wires, or a plurality of lighting members arranged in parallel in the direction of extension of the group of electric wires.

[0010] According to this configuration, since it includes lighting members that extend along the direction of the wire group's extension, or multiple lighting members arranged in parallel along the direction of the wire group's extension, it becomes possible to easily confirm the position of the wire harness when opening the sliding door, even at night. Therefore, the risk of the wire harness being stepped on can be reduced.

[0011] [2] In the above [1], the lighting member may include a light-emitting member and a light guide that extends along the direction of extension of the group of electric wires and guides and disperses the light supplied from the light-emitting member along its own direction of extension.

[0012] According to this configuration, the lighting component includes a light-emitting component and a light guide that extends along the direction of extension of the wire group and guides and disperses the light supplied from the light-emitting component along its own direction of extension, thus enabling good visibility with a simple configuration. For example, even with a simple configuration of a light-emitting component and a single light guide, it is possible to create a configuration that emits light continuously over a long distance in the direction of extension of the wire group.

[0013] [3] In the above [2], the present invention may also include an outer covering member that extends along the extending direction of the group of electric wires and covers the group of electric wires, and a plurality of fixing members having a fixing portion fixed to a part of the extending direction of the outer covering member and a holding portion that holds the light guide, and being arranged at intervals in the extending direction of the outer covering member.

[0014] According to this configuration, the light guide can be easily routed along the wire harness because it has multiple fixing members, each having a fixing portion fixed to a part of the extending direction of the exterior member and a holding portion that holds the light guide, and these fixing members are spaced apart in the extending direction of the exterior member.

[0015] [4] In [3] above, the holding part may be configured to hold the light guide from a direction intersecting the extending direction of the light guide. According to this configuration, since the holding part is configured to hold the light guide from a direction intersecting the extending direction of the light guide, for example, there is no need to pass the light guide along the extending direction in advance, so-called retrofitting is possible, and the assembling property is improved.

[0016] [5] In [3] or [4] above, the fixing part may be configured to be fixed to the exterior member from a direction intersecting the extending direction of the exterior member. According to this configuration, since the fixing part is configured to be fixed to the exterior member from a direction intersecting the extending direction of the exterior member, for example, there is no need to pass the exterior member along the extending direction in advance, so-called retrofitting is possible, and the assembling property is improved.

[0017] [6] In any one of [5] above, the exterior member is a rubber boot having a bellows structure by repeating concavities and convexities in the extending direction, and the fixing part may be formed to fit into the concave part in the bellows structure of the rubber boot.

[0018] According to this configuration, since the fixing part is formed to fit into the concave part in the bellows structure of the rubber boot as the exterior member, it is possible to prevent displacement in the extending direction of the exterior member with a simple structure.

[0019] [7] In any one of [1] to [6] above, it may include a plurality of separate veils that cover the wire group and are arranged side by side along the extending direction of the wire group and are rotatably connected to each other.

[0020] This configuration includes multiple separate carriers that cover the wire group and are arranged in parallel along the direction of the wire group's extension, while being rotatably connected to one another. For example, this allows for the stabilization of the wire harness's position. In a configuration where the wire group is simply covered by a corrugated tube, the wire harness can bend freely at any point along its extension, and the way it bends may change due to deterioration, resulting in an unstable wire harness position. In contrast, the multiple separate carriers maintain a consistent bend even with repeated opening and closing of the sliding door, thus stabilizing the wire harness's position. Therefore, for example, it is possible to prevent the wire harness from sticking out to a position where it is easily stepped on.

[0021] The lighting system of this disclosure is [8] The device comprises a wire harness as described in any one of [1] to [7] above, and a power control device that supplies power to the lighting member when the sliding door is in the open position.

[0022] According to this configuration, when the sliding door is opened, power is supplied to the lighting component by the power control device, so the position of the wire harness can be easily confirmed when the sliding door is open, even at night.

[0023] [9] In the above [8], the power supply control device may supply power to the lighting member such that it lights up differently when the sliding door is in operation and when the sliding door is fully open.

[0024] According to this configuration, power is supplied to the lighting component so that it lights up differently when the sliding door is in operation and when the sliding door is fully open. For example, the user can recognize when the sliding door is in operation.

[0025]

[10] In the above [8] or [9], the power supply control device may also supply power to the lighting member when the sliding door is fully closed. According to this configuration, power is supplied to the lighting components even when the sliding door is fully closed, allowing for effects such as illumination.

[0026]

[11] In any one of the above [8] to

[10] , a switch may be provided that can switch between supplying and stopping power to the lighting member when the sliding door is in the fully closed position.

[0027] According to this configuration, when the sliding door is fully closed, a switch is provided to toggle the power supply to the lighting component on and off, so that, for example, passengers can illuminate the lighting component as needed.

[0028] [Details of the embodiments of this disclosure] A specific example of the lighting system described herein will be explained below with reference to the drawings. In each drawing, some parts of the configuration may be exaggerated or simplified for ease of explanation. Also, the dimensional ratios of each part may differ in each drawing.

[0029] In this specification, terms such as “first,” “second,” etc., are used solely to distinguish between subjects and do not rank them. The present invention is not limited to these examples and is shown in the claims, and all modifications within the meaning and scope equivalent to the claims are intended.

[0030] (Configuration of Lighting System 1) As shown in Figures 1 to 3, the lighting system 1 comprises a wire harness 10 and a power control device 100. The lighting system 1 is installed on the vehicle body 20 and the sliding door 30.

[0031] (Configuration of wire harness 10) The wire harness 10 includes a group of wires 11 routed from the vehicle body 20 to the sliding door 30. The group of wires 11 electrically connects a power control device 100 installed on the vehicle body 20 to electrical equipment (not shown) installed on the sliding door 30. The electrical equipment is, for example, a power window motor or a lock actuator, and the power control device 100 is a device for supplying power to that electrical equipment. The vehicle body 20 has an opening 21 that can be opened and closed by the sliding door 30. The vehicle body 20 is also provided with an entry / exit step 22. The entry / exit step 22 is located in a part corresponding to the sliding door 30, and is provided in a part on the inside (upper side in Figure 1) of the opening 21, rather than the outside (lower side in Figure 1) end. The entry / exit step 22 is for the user to place their feet when getting in and out of the vehicle. The sliding door 30 is also provided so as to be able to slide forward and backward (left and right in Figure 1) of the vehicle body 20 by a mechanism (not shown). More specifically, the sliding door 30 is capable of sliding from a fully closed state (see Figure 1) to the outside of the vehicle body 20 (lower side in Figure 1) while sliding towards the rear of the vehicle body 20 (left side in Figure 2) by a mechanism not shown, and can slide all the way to a fully open state (see Figure 3).

[0032] As shown in Figure 6, the wire harness 10 comprises a group of wires 11, a plurality of separate carriers 12, a rubber boot 13 as an exterior component, a plurality of fixing members 14, and a light guide 41 that constitutes part of the lighting component 40. Note that Figure 6 shows a part of the wire harness 10 in a partially disassembled state. The group of wires 11 is made up of bundles of multiple wires, but in the figure, the individual wires are omitted from the illustration and are shown schematically as a single unit.

[0033] (Configuration of multiple separate vanes 12) Multiple separate carriers 12 are made of resin material. Multiple separate carriers 12 cover the group of electric wires 11 and are arranged side by side along the direction of extension of the group of electric wires 11, while being rotatably connected to one another.

[0034] Specifically, each of the multiple separate carriers 12 has a U-shaped separate carrier body 15 with an opening on one side that intersects the direction in which the group of electric wires 11 extends, and a carrier cover 16 fixed to close the opening of the separate carrier body 15.

[0035] Each separate carrier body 15 has a pivot shaft portion 15a at its first end and a rotatable shaft portion 15b at its second end to which the pivot shaft portion 15a can be connected. Each of the multiple separate carrier bodies 15 is rotatable relative to an adjacent separate carrier body 15 by having its pivot shaft portion 15a rotatably connected to the rotatable shaft portion 15b of an adjacent separate carrier body 15.

[0036] As shown in Figures 7 and 8, the multiple separate carriers 12 of this embodiment are of two types: a first separate carrier 12A (see Figure 7) and a second separate carrier 12B (see Figure 8), each with a different rotatable angle. As shown in Figure 7, the first separate carrier 12A is rotatable 15° counterclockwise in the first rotation direction from a straight position, and 30° clockwise in the second rotation direction from a straight position. As shown in Figure 8, the second separate carrier 12B is not rotatable counterclockwise in the first rotation direction from a straight position, and 45° clockwise in the second rotation direction from a straight position. The rotatable angle of the separate carrier 12 is set by a known structure, such as changing the shape of the engagement portion with adjacent separate carriers 12.

[0037] The multiple separate carriers 12 are arranged so that the wire harness 10 does not protrude beyond the overhang prevention line Z (see Figure 3) towards the vehicle body 20 (upper side in Figure 3), with the first separate carrier 12A and the second separate carrier 12B being combined. The overhang prevention line Z is a line set for each vehicle model, for example, along the vehicle body 20 to maintain a certain distance from the vehicle body 20.

[0038] As shown in Figure 3, in this embodiment, for example, a second separate carrier 12B (see Figure 8) is used in the intermediate range X of the wire harness 10. This prevents the wire harness 10 from protruding beyond the overhang prevention line Z towards the vehicle body 20 (upper side in Figure 3). Therefore, the wire harness 10 is prevented from colliding with the vehicle body 20. In areas of the wire harness 10 other than the intermediate range X, a first separate carrier 12A (see Figure 7) is used. Of course, the combination of the first separate carrier 12A and the second separate carrier 12B may be appropriately changed according to, for example, the overhang prevention line Z set for each vehicle model.

[0039] (Composition of rubber boots 13) The rubber boot 13 is made of rubber material. As shown in Figure 6, the rubber boot 13 extends along the direction of extension of the wire group 11 and is provided to cover the wire group 11. More specifically, the rubber boot 13 is provided to cover a plurality of rotatably connected separate carriers 12. The rubber boot 13 has a bellows structure formed by repeating indentations and protrusions in the direction of extension. The rubber boot 13 is formed to be easily bent by its bellows structure, allowing the rotation of the plurality of separate carriers 12.

[0040] (Configuration of lighting component 40) As shown in Figures 1 to 3, the lighting member 40 includes a light guide 41 and a light-emitting member 42. The light-emitting member 42 in this embodiment is, for example, a light-emitting diode, i.e., an LED. The color of light emitted by the light-emitting member 42 in this embodiment is white. The light-emitting member 42 is connected to a power control device 100 provided on the vehicle body 20 and emits light when power is supplied from the power control device 100. The light guide 41 is formed in an elongated shape and guides and disperses the light supplied from the light-emitting member 42 along its own extending direction. In other words, the first end of the light guide 41 is connected to the light-emitting member 42 and guides and disperses the light supplied from the light-emitting member 42 toward the second end. The light guide 41 is provided on the wire harness 10 so as to extend along the extending direction of the wire group 11. The light guide 41 in this embodiment is provided along the entire length of the wire harness 10 in its extending direction. The light guide 41 is fixed to the rubber boot 13 by multiple fixing members 14.

[0041] (Configuration of the fixing member 14) As shown in Figure 6, the multiple fixing members 14 are arranged at intervals in the extending direction of the rubber boot 13. Each of the multiple fixing members 14 has a fixing portion 14a that is fixed to a part of the extending direction of the rubber boot 13 and a holding portion 14b that holds the light guide 41. The fixing portion 14a is configured to be fixable to the rubber boot 13 from a direction intersecting the extending direction of the rubber boot 13. The fixing portion 14a is formed to fit into a recess 13a in the bellows structure of the rubber boot 13. The holding portion 14b is configured to hold the light guide 41 from a direction intersecting the extending direction of the light guide 41.

[0042] More specifically, as shown in Figure 5, the fixing part 14a has an upper piece 14c, side pieces 14d extending parallel downwards from both sides of the upper piece 14c, and claw pieces 14e extending toward each other from the tips of the side pieces 14d. The fixing part 14a is then fixed to the rubber boot 13 (see Figure 6) by being fitted onto the recess 13a of the rubber boot 13 from above while being bent so that the space between the claw pieces 14e widens.

[0043] Furthermore, as shown in Figure 5, the holding portion 14b has an arc-shaped piece 14f that extends in an arc shape along the upper piece 14c from the upper surface of the upper piece 14c, and an introduction piece 14g that extends upward along the upper piece 14c from the tip of the arc-shaped piece 14f. The holding portion 14b holds the light guide 41 (see Figure 6) by fitting it into the holding portion 14b from the side while the arc-shaped piece 14f is bent so that the space between the tip of the arc-shaped piece 14f and the upper piece 14c widens. In other words, the light guide 41 is held by the holding portion 14b by passing between the upper piece 14c and the introduction piece 14g and being inserted between the upper piece 14c and the arc-shaped piece 14f.

[0044] As shown in Figures 1 to 3, the light guide 41, fixed as described above, is positioned in the center in the width direction on the upper surface of the wire harness 10, and bends together with the wire harness 10 when the sliding door 30 operates.

[0045] As shown in Figure 4, the light guide 41 in this embodiment is configured to be positioned above the floor F when the sliding door 30 is fully closed. In Figure 4, a door trim 31 provided on the sliding door 30 is shown, and the wire harness 10 is positioned below the door trim 31 when the sliding door 30 is fully closed.

[0046] (Configuration of the power control device 100) The power control device 100 is electrically connected to a battery (not shown), a courtesy switch (not shown), etc. When the sliding door 30 is in the open state (see Figures 2 and 3), the power control device 100 supplies power to the lighting member 40, more specifically to the light-emitting member 42 of the lighting member 40. In this embodiment, the open state of the sliding door 30 includes the half-open state (see Figure 2) during operation of the sliding door 30 and the fully open state (see Figure 3). Furthermore, in this embodiment, the power control device 100 also supplies power to the light-emitting member 42 of the lighting member 40 when the sliding door 30 is in the fully closed state (see Figure 1).

[0047] Furthermore, as shown in Figure 1, the lighting system 1 of this embodiment includes a switch 50. The switch 50 is electrically connected to the power control device 100. The switch 50 is located in a position where it can be operated by the passenger. The switch 50 is configured to switch between supplying and stopping power to the light-emitting member 42 of the lighting member 40 when the sliding door 30 is fully closed.

[0048] (Operation of this embodiment) Next, the operation of the lighting system 1 configured as described above will be explained. For example, when the sliding door 30 is in the open position (see Figures 2 and 3), power is supplied from the power control device 100 to the light-emitting member 42 of the lighting member 40. As a result, the light-emitting member 42 emits light, and the entire length of the light guide 41 in its extending direction becomes illuminated. Therefore, even at night, for example, the user can easily see the position of the wire harness 10 including the light guide 41 when getting in or out of the vehicle.

[0049] Furthermore, in this embodiment, even when the sliding door 30 is fully closed, power is supplied from the power control device 100 to the light-emitting member 42 of the lighting member 40, causing the entire length of the light guide 41 in its extending direction to light up. Therefore, for example, passengers can enjoy the light guide 41 as an illumination.

[0050] (Effects of this embodiment) Next, the effects of the above embodiment are described below. (1) The wire harness 10 is equipped with a lighting member 40 that extends along the direction of extension of the wire group 11, so that, for example, even at night, when the sliding door 30 is opened, the user can easily confirm the position of the wire harness 10. This reduces the risk of the wire harness 10 being stepped on. Specifically, for example, when the sliding door 30 is open, a lower arm (not shown) which is part of the opening and closing mechanism of the sliding door 30 may be positioned below the wire harness 10. In such cases, there is a risk that the wire harness 10 may be stepped on, especially when children try to put their feet on the lower arm when getting in or out, but the light guide 41 of the lighting member 40 illuminates, making it less likely to be stepped on. In addition, the illumination of the light guide 41 of the lighting member 40 improves the visibility of the surrounding area, including the lower arm, and improves the visibility of, for example, the "no stepping" mark written on the lower arm, making it less likely for the lower arm and the wire harness 10 to be stepped on.

[0051] (2) The lighting member 40 includes a light-emitting member 42 and a light guide 41 that extends along the direction of extension of the wire group 11 and guides and disperses the light supplied from the light-emitting member 42 along its own direction of extension before emitting it. Thus, good visibility can be achieved with a simple configuration. For example, even with a simple configuration of a light-emitting member 42 and a single light guide 41, it is possible to create a configuration that emits light continuously over a long distance in the direction of extension of the wire group 11. In this configuration, for example, fewer parts are required than if multiple light-emitting members such as numerous LEDs were arranged in parallel in the direction of extension of the wire group 11.

[0052] (3) The rubber boot 13 has a fixing portion 14a which is fixed to a part of the extending direction of the rubber boot 13 and a holding portion 14b which holds the light guide 41, and a plurality of fixing members 14 which are spaced apart in the extending direction of the rubber boot 13.Therefore, the light guide 41 can be easily routed along the wire harness 10.

[0053] (4) The holding portion 14b is configured to hold the light guide 41 from a direction intersecting the extending direction of the light guide 41, so for example, it is not necessary to pass the light guide 41 along the extending direction in advance, and so-called retrofitting is possible. Therefore, assembly is easy.

[0054] (5) The fixing part 14a is configured to be fixed to the rubber boot 13 from a direction intersecting the extending direction of the rubber boot 13, so for example, it is not necessary to pass the rubber boot 13 along the extending direction in advance, and so-called retrofitting is possible. Therefore, assembly is easy.

[0055] (6) Since the fixing portion 14a is formed to fit into the recess 13a in the bellows structure of the rubber boot 13, it is possible to prevent displacement of the rubber boot 13 in the extending direction with a simple configuration.

[0056] (7) The wire harness 10 includes a plurality of separate carriers 12 that cover the wire group 11 and are arranged in parallel along the direction of extension of the wire group 11, and are rotatably connected to each other. For example, the position of the wire harness 10 can be stabilized. For example, if the wire group 11 is simply covered with a corrugated tube, the wire harness 10 can bend freely at any point in the direction of extension, and the way it bends may change due to deterioration, etc., so the position of the wire harness 10 is not stable. In contrast, the plurality of separate carriers 12 can maintain a constant bend even when the sliding door 30 is opened and closed repeatedly, so the position of the wire harness 10 can be stabilized. Therefore, for example, it is possible to prevent the wire harness 10 from sticking out to a position where it is easily stepped on.

[0057] Furthermore, if the wire group 11 is simply covered with a corrugated tube, when bent, the entire structure tends to form a large arc, which could cause it to penetrate areas where it is not intended to penetrate, and consequently, to come into contact with other components. In contrast, the multiple separate carriers 12 can maintain a consistent bending pattern, thus reliably preventing contact with other components. Specifically, the wire harness 10 is prevented from protruding beyond the overhang prevention line Z towards the vehicle body 20, thereby preventing collision with the vehicle body 20.

[0058] (8) When the sliding door 30 is in the open position, the power supply control device 100 supplies power to the light-emitting member 42 of the lighting member 40, so that the position of the wire harness 10 can be easily confirmed when the sliding door 30 is open, even at night.

[0059] (9) Even when the sliding door 30 is fully closed, power is supplied to the light-emitting member 42 of the lighting member 40 by the power control device 100, so that it can have an illumination effect, for example.

[0060] (10) When the sliding door 30 is fully closed, a switch 50 is provided that can switch between supplying and stopping power to the light-emitting member 42 of the lighting member 40, so that, for example, a passenger can illuminate the light guide 41 of the lighting member 40 as needed.

[0061] (Example of change) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0062] In the above embodiment, the light guide 41 is set to be positioned above the floor F inside the vehicle when the sliding door 30 is fully closed, but this is not limited to this configuration. For example, as shown in Figure 9, the light guide 41 may be configured to be positioned below the floor F. In this case, the light leaking from below the floor F can, for example, create an illumination effect.

[0063] In the above embodiment, the power control device 100 is configured to supply power so that the light-emitting member 42 of the lighting member 40 lights up when the sliding door 30 is fully closed, when the sliding door 30 is fully open, and while the sliding door 30 is in operation, but the invention is not limited to this configuration.

[0064] For example, the power control device 100 may be configured to supply power to the light-emitting member 42 of the lighting member 40 so that it lights up differently when the sliding door 30 is in operation and when the sliding door 30 is fully open. Specifically, for example, the power control device 100 may supply power so that the light-emitting member 42 blinks when the sliding door 30 is in operation, and so that the light-emitting member 42 lights up when the sliding door 30 is fully open. Alternatively, for example, the power control device 100 may supply power to the light-emitting member 42 so that it lights up in a different color when the sliding door 30 is in operation than when the sliding door 30 is fully open, for example, red. In this case, the light-emitting member 42 needs to be configured to light up in multiple colors.

[0065] In this way, the lighting component 40 illuminates differently when the sliding door 30 is in operation and when the sliding door 30 is fully open, so for example, the user can recognize that the sliding door 30 is in operation.

[0066] In the above embodiment, the lighting member 40 includes a light guide 41 and a light-emitting member 42, but it is not limited to this and may be changed to a lighting member with other configurations that extend along the direction of extension of the wire group 11. Also, although the lighting member 40 is assumed to light up when power is supplied, it is not limited to this.

[0067] For example, the lighting component may be a rubber boot 13 containing a phosphorescent material. That is, the rubber material that makes up the rubber boot 13 may contain a phosphorescent material. The phosphorescent material is a material that stores light and emits light even after the light source is turned off.

[0068] Furthermore, the lighting member 40 may be changed to a lighting member of a different configuration, which is arranged in parallel in the direction of extension of the wire group 11. For example, the lighting member may be a plurality of light-emitting members such as LEDs, which are arranged in parallel in the direction of extension of the wire group 11. Specifically, for example, the plurality of fixing members 14 shown in Figures 1 to 3 may be changed to a plurality of light-emitting members such as LEDs fixed to the outer circumference of the rubber boot 13.

[0069] Even in this way, the user can easily confirm the position of the wire harness 10. Therefore, the risk of the wire harness 10 being stepped on can be reduced.

[0070] In the above embodiment, the wire harness 10 is provided with a plurality of fixing members 14, each having a fixing portion 14a fixed to a part of the extending direction of the rubber boot 13 and a holding portion 14b that holds the light guide 41. However, it is not limited to this. That is, the light guide 41 may be provided on the wire harness 10 in other configurations.

[0071] In the above embodiment, the holding portion 14b of the fixing member 14 is configured to hold the light guide 41 from a direction intersecting the extending direction of the light guide 41, but the embodiment is not limited to this.
