Mode for Carrying Out the Invention

[0011] Embodiments for carrying out the present invention will be described in detail with reference to the drawings. The present invention is not limited by the content described in the following embodiments. Further, the constituent elements described below include those that can be easily assumed by those skilled in the art and those that are substantially the same. Furthermore, the configurations described below can be combined as appropriate. Also, various omissions, substitutions, or changes in the configuration can be made without departing from the gist of the present invention.

[0012] 〔Embodiment〕 The wire harness routing structure 1, the link type sliding door SD, and the wire harness WH according to the embodiment will be described with reference to the drawings.

[0013] In the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "extending direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z (intersecting direction Z)". The extending direction X, the width direction Y, and the height direction Z intersect each other and are typically orthogonal. The extending direction X is, for example, a direction along the direction in which the main link arm 11 described later extends (longitudinal direction). The width direction Y is, for example, a direction along the short side direction of the main link arm 11. The height direction Z is a direction along the vehicle height direction (vehicle height direction) of the vehicle and is also a direction along the vertical direction. The sliding direction S of the door body D is a direction along the extending direction X of the main link arm 11 in a state where the door body D is closed, and here, it corresponds to a direction along the entire length direction of the vehicle body B. In other words, the sliding direction S of the door body D is a direction that intersects the rotation axis of the main link arm 11 (the rotation axis portions 12a and 13a described later) and is typically a direction orthogonal to the rotation axis. Each direction used in the following description represents the direction in a state where each part is assembled to each other unless otherwise specified.

[0014] The wire harness routing structure 1 is applied to a vehicle and supports the door body D so as to be slidable along the sliding direction S (the longitudinal direction of the vehicle body B) with respect to the vehicle body B of the vehicle, and also electrically connects a connection target BC1 such as a device or a connector provided on the vehicle body B side and a connection target DC1 such as a device or a connector provided on the door body D side. As shown in FIGS. 1 to 4, the wire harness routing structure 1 includes a routing wire W, a main link mechanism 10, a sub-link mechanism 20, a lid portion 30, and a bundling member 40. The routing wire W, the lid portion 30, and the bundling member 40 constitute a wire harness WH. In other words, it can also be said that the wire harness WH includes the routing wire W, the lid portion 30, and the bundling member 40. Further, the door body D, the main link mechanism 10, the sub-link mechanism 20, the lid portion 30, the bundling member 40, and the routing wire W constitute a link type sliding door SD. In other words, it can also be said that the link type sliding door SD includes the door body D, the main link mechanism 10, the sub-link mechanism 20, the lid portion 30, the bundling member 40, and the routing wire W.

[0015] Here, the wire harness routing structure 1 supports the door body D by the main link mechanism 10 and the sub-link mechanism 20, and by rotating the main link arm 11 and the sub-link arm 21 described later, without using a general guide rail for sliding, it is a routing structure when sliding the door body D along the sliding direction S with respect to the vehicle body B. Hereinafter, the wire harness routing structure 1 will be described in detail.

[0016] The routing wire W connects the connection target BC1 provided on the vehicle body B side and the connection target DC1 provided on the door body D side. The routing wire W is configured to include a power line for supplying power, a communication line for performing communication, and the like. The routing wire W is routed, for example, between the vehicle body B and the door body D, and connects the connection target BC1 including a connector or a device on the vehicle body B side and the connection target DC1 including a connector or a device on the door body D side.

[0017] The main link mechanism 10 is a mechanism that supports the door body D so as to be slidable with respect to the vehicle body B together with the sub-link mechanism 20. The main link mechanism 10 includes a main link arm 11, a first connecting portion 12, and a second connecting portion 13.

[0019] The first arm 11a is a metal member that extends along the extending direction X and is formed in a long shape. The first arm 11a is formed, for example, in a shape having a bent portion that bends from the vehicle body B side to the door body D side. Note that the first arm 11a is not limited to such a bent shape as long as it can support the door body D so as to be slidable with respect to the vehicle body B. The first arm 11a includes a bottom surface portion 11h and a pair of side wall portions 11i. The bottom surface portion 11h is a portion located on one side (lower side) in the height direction Z and is formed in a long and flat plate shape along the extending direction X. Each of the pair of side wall portions 11i is formed in a long and flat plate shape along the extending direction X, stands upright along the height direction Z from both ends in the width direction Y of the bottom surface portion 11h, and is positioned at a certain interval along the width direction Y. The first arm 11a has an opening on the other side (upper side) in the height direction Z of the bottom surface portion 11h, and both end portions in the extending direction X are closed. The first arm 11a configured in this way accommodates a cable wire W that is routed between the vehicle body B side and the door body D side in a groove portion 11d, which is formed surrounded by the bottom surface portion 11h and the pair of side wall portions 11i and will be described later.

The second arm 11b is formed, for example, in a shape having a bent portion that bends from the vehicle body B side to the door body D side. Note that the second arm 11b is not limited to such a bent shape as long as it can support the door body D so as to be slidable with respect to the vehicle body B. The second arm 11b is arranged side by side with the first arm 11a along the height direction Z. The second arm 11b includes a bottom surface portion 11m and a pair of side wall portions 11n. The bottom surface portion 11m is a portion located on one side (lower side) in the height direction Z, and is formed in an elongated and flat plate shape along the extending direction X. Each of the pair of side wall portions 11n is formed in an elongated and flat plate shape along the extending direction X, stands upright along the height direction Z from both ends in the width direction Y of the bottom surface portion 11m, and is positioned at a certain interval along the width direction Y. The second arm 11b has an opening on the other side (upper side) in the height direction Z of the bottom surface portion 11m, and both end portions in the extending direction X are closed. The second arm 11b configured as described above can accommodate a wiring line W that is routed between the vehicle body B side and the door body D side in a groove portion 11e, which is formed and surrounded by the bottom surface portion 11m and the pair of side wall portions 11n and will be described later.

The closing portion 31 is, for example, a portion for pulling out the wiring line W in the groove portion 11d accommodated in the groove portion 11d to the outside, that is, closes the remaining portion of the opening of the groove portion 11d with a part of the opening of the groove portion 11d opened. That is, the closing portion 31 does not close the portion for pulling out the wiring line W in the groove portion 11d to the outside. Specifically, the closing portion 31 closes the remaining portion of the opening of the groove portion 11d with the portion for pulling out the wiring line W in the groove portion 11d to the vehicle body B side opened on one side in the extending direction X of the groove portion 11d and the portion for pulling out the wiring line W in the groove portion 11d to the door main body D side opened on the other side in the extending direction X of the groove portion 11d.

[0052] The holding part 32 holds the wiring line W and has a pair of wall parts 32a (see FIG. 5). The pair of wall parts 32a are each formed in a long and flat plate shape along the extending direction X, stand up from both sides in the width direction Y of the closing part 31 of the lid part 30 along the height direction Z toward the groove part 11d, and are positioned at a constant interval along the width direction Y. The interval in the width direction Y between one wall part 32a and the other wall part 32a is equal to or less than the diameter of the wiring line W. The pair of wall parts 32a hold the wiring line W by sandwiching the wiring line W between one wall part 32a and the other wall part 32a.

[0053] Next, the bundling member 40 will be described. The bundling member 40 bundles and fixes the wiring line W to the lid part 30. As shown in FIG. 5, the bundling member 40 is formed in a band shape and is inserted along the width direction Y into a hole provided on the closing part 31 side of the holding part 32. Then, the bundling member 40 is inserted into the gap between the wiring line W held by the holding part 32 and the closing part 31, and the holding part 32 and the wiring line W are bundled by the inserted bundling member 40 to fix the wiring line W to the holding part 32. The bundling member 40 is provided at two locations at a constant interval along the extending direction X of the lid part 30, and fixes the wiring line W to the holding part 32 on one side in the extending direction X of the lid part 30 and on the other side in the extending direction X of the lid part 30.

[0054] As described above, the wire harness WH is configured to include a wiring wire W, a lid portion 30, and a bundling member 40. For example, in a state where the wiring wire W, the lid portion 30, and the bundling member 40 are assembled to each other, it is assembled to the groove portion 11d of the main link arm 11 of the vehicle body B and routed across the vehicle body B and the door body D. Thereby, the wire harness WH improves the assemblability to the vehicle body B. That is, here, the lid portion 30 is assembled to the groove portion 11d of the first arm 11a in a state where the wiring wire W is held by the holding portion 32 and the wiring wire W is fixed to the holding portion 32 by the bundling member 40. At this time, the lid portion 30 is fixed to the groove portion 11d, for example, by a locking portion (not shown) provided on the lid portion 30 being locked to a locked portion (not shown) provided on the groove portion 11d. Then, the wiring wire W is accommodated in the accommodation space portion of the groove portion 11d of the first arm 11a, and is routed along the first arm 11a with the opening of the groove portion 11d closed by the lid portion 30, and electrically connects the connection target BC1 on the vehicle body B side and the connection target DC1 on the door body D side.

[0055] The wire harness routing structure 1 configured as described above is rotated, for example, by a drive unit (not shown) including a motor or the like provided on the vehicle body B, so that the main link arm 11 is rotated. The drive unit is connected, for example, to the rotation axis of the main link arm 11 via a gear or the like that transmits rotational force, and rotates the main link arm 11 by rotating the rotation axis. When the main link arm 11 is rotated by the drive unit in the wire harness routing structure 1, the main link arm 11 and the sub-link arm 21 rotate relative to the vehicle body B and the door body D, respectively, and slide the door body D relative to the vehicle body B along the slide direction S from the fully closed position to the fully open position, or from the fully open position to the fully closed position. That is, when the main link arm 11 is rotated by the drive unit, the main link arm 11 rotates relative to the vehicle body B and the door body D with the rotation axis portion 12a of the first connection portion 12 and the rotation axis portion 13a of the second connection portion 13 as rotation axes. At this time, when the main link arm 11 is rotated by the drive unit, the sub-link arm 21 rotates relative to the vehicle body B and the door body D with the rotation axis portion 22a of the first connection portion 22 and the rotation axis portion 23a of the second connection portion 23 as rotation axes. Then, the wiring line W routed along the main link arm 11 and housed in the accommodation space portion of the groove portion 11d electrically connects the connection target BC1 on the vehicle body B side and the connection target DC1 on the door body D side while the main link arm 11 is rotating.

[0056] As described above, the wire harness routing structure 1 according to the embodiment includes at least the main link arm 11 and the wiring line W. One end of the main link arm 11 is rotatably connected to the vehicle body B, and the other end is rotatably connected to the door body D. While rotating relative to the vehicle body B and the door body D, the main link arm 11 slidably supports the door body D relative to the vehicle body B. The wiring line W is routed along the main link arm 11 and connects the connection target on the vehicle body B side and the connection target on the door body D side. The main link arm 11 includes a groove portion 11d formed in a groove shape along the extending direction X in which the main link arm 11 extends and capable of housing the wiring line W.

[0057] With this configuration, the wire harness routing structure 1 can secure a routing space for routing the wire W between the vehicle body B and the door body D by means of the groove portion 11d of the main link arm 11. Further, the wire harness routing structure 1 can suppress the wire W from being exposed to the outside by housing and routing the wire W routed between the vehicle body B and the door body D in the groove portion 11d of the main link arm 11, and can suppress the wire W from being caught as compared with the case where the wire W is exposed to the outside as in the prior art. As a result, the wire harness routing structure 1 can properly route the wire W between the vehicle body B and the door body D.

[0058] The wire harness routing structure 1 further includes a lid portion 30 that closes an opening on the height direction Z side that intersects the extending direction X of the groove portion 11d. With this configuration, the wire harness routing structure 1 can protect the wire W by closing the opening of the groove portion 11d with the lid portion 30 in a state where the wire W is housed in the groove portion 11d of the main link arm 11. Further, the wire harness routing structure 1 can hide the wire W from the outside with the lid portion 30, improving the appearance. Further, the wire harness routing structure 1 can omit separately applying a design to the main link arm 11 by applying a design to the lid portion 30 of the main link arm 11.

[0059] In the wire harness routing structure 1, the lid portion 30 includes a closing portion 31 that closes the opening of the groove portion 11d and a holding portion 32 that is provided on the closing portion 31 and holds the wire W. With this configuration, the wire harness routing structure 1 can house and route the wire W in the groove portion 11d by assembling the lid portion 30 in a state where the wire W is held by the holding portion 32 to the groove portion 11d of the main link arm 11. That is, the wire harness routing structure 1 can simultaneously perform the operation of closing the opening of the groove portion 11d and the operation of housing and routing the wire W in the groove portion 11d.

[0060] The wire harness routing structure 1 is formed in a strip shape and further includes a bundling member 40 that bundles the lid portion 30 and the wire W and fixes the wire W to the lid portion 30. With this configuration, the wire harness routing structure 1 can maintain the state in which the wire W is fixed to the lid portion 30 even after the wire W is housed in the groove portion 11d and routed, and can suppress the wire W from rattling within the groove portion 11d due to vibrations generated when the door body D is opened and closed.

[0061] The link type slide door SD includes a door body D assembled to the vehicle body B, a main link arm 11, and a wire W. The main link arm 11 is configured to include a groove portion 11d formed in a groove shape along the extending direction X in which the main link arm 11 extends and capable of accommodating the wire W. With this configuration, the link type slide door SD can secure a routing space for the wire W between the vehicle body B and the door body D by the groove portion 11d of the main link arm 11, and can properly route the wire W between the vehicle body B and the door body D.

[0062] The wire harness WH is routed along the main link arm 11, connects the connection target BC1 on the vehicle body B side and the connection target DC1 on the door body D side, and includes a wire W housed in the groove portion 11d of the main link arm 11 formed in a groove shape along the extending direction X. With this configuration, the wire harness WH can properly route the wire W between the vehicle body B and the door body D by the wire W being housed in the groove portion 11d of the main link arm 11.

[0063] 〔Modification example〕 Although an example in which the wire harness routing structure 1 includes a lid portion 30 that closes the opening on the height direction Z side of the groove portion 11d has been described, the present invention is not limited thereto, and the lid portion 30 may not be provided.

[0064] Although an example in which the lid portion 30 includes a holding portion 32 that holds the wire W has been described, the present invention is not limited thereto, and the holding portion 32 may not be included.

[0065] Although the wire harness routing structure 1 has been described as an example including a bundling member 40 that fixes the routing wire W to the lid portion 30, the present invention is not limited thereto, and the bundling member 40 may not be provided.

[0066] Although the wire harness routing structure 1 has been described as an example in which the main link arm 11 is rotated by a drive unit, and thus the main link arm 11 and the sub-link arm 21 relatively rotate with respect to the vehicle body B and the door main body D, respectively, the present invention is not limited thereto. For example, without providing a drive unit, the main link arm 11 and the sub-link arm 21 may relatively rotate with respect to the vehicle body B and the door main body D, respectively, by a sliding operation of the door main body D by an occupant of the vehicle.

[0067] Although the groove portions 11d, 11e, and 21b have been described as an example in which their cross-sections are formed in a rectangular shape, the present invention is not limited thereto. For example, their cross-sections may be formed in a U shape, C shape, H shape, etc. with a curved bottom surface.

For example, the bottom surface portion 11h may be located on one side in the width direction Y, and the other side in the width direction Y of the bottom surface portion 11h may be open. In this case, the pair of side wall portions 11i are provided on both sides in the height direction Z. Similarly, for the groove portions 11e and 21b, the bottom surface portions 11m and 21c may be located on one side in the width direction Y, and the other side in the width direction Y of the bottom surface portions 11m and 21c may be open. In this case, the pair of side wall portions 11n and 21d are provided on both sides in the height direction Z.

[0069] Although the main link arm 11 has been described as an example in which both end pivot shafts 12a and 13a in a single arm member rotate about the pivot shafts, the present invention is not limited thereto. For example, the main link arm 11 may be configured such that the respective divided arms are connected by a link after being divided in the extending direction X. In this case, groove portions are formed in the respective divided arms, the respective groove portions are continuous across the respective divided arms, and the routing wire W may be routed in the groove portions continuous across the respective divided arms.

[0070] Although the example where the sub-link arm 21 rotates about the rotation shaft portions 22a and 23a at both ends as the rotation shafts in one arm member has been described, the present invention is not limited thereto. For example, it may be configured such that the respective divided arms are connected by links after being divided in the extending direction X. In this case, groove portions are formed in the respective divided arms, the respective groove portions are continuous across the respective divided arms, and the wiring line W may be wired in the groove portions continuous across the respective divided arms.

[0071] Although the example where the wire harness wiring structure 1 includes two link mechanisms, i.e., the main link mechanism 10 and the sub-link mechanism 20, has been described, the present invention is not limited thereto, and it may be one link mechanism (for example, a mechanism including only the main link mechanism 10 without including the sub-link mechanism 20).

[0072] Although the example where the main link mechanism 10 wires the wiring line W to the first arm 21a and does not wire the wiring line W to the second arm 11b has been described, the present invention is not limited thereto, and the wiring line W may also be wired to the second arm 11b. In this case, with the wiring line W accommodated in the groove portion 11e of the second arm 11b, the opening of the groove portion 11e of the second arm 11b is closed by the lid portion 30.

[0073] Although the example where the sub-link mechanism 20 does not wire the wiring line W to the first arm 21a has been described, the present invention is not limited thereto, and the wiring line W may also be wired to the first arm 21a. In this case, with the wiring line W accommodated in the groove portion 21b of the first arm 21a, the opening of the groove portion 21b of the first arm 21a is closed by the lid portion 30.
