MODE FOR CARRYING OUT THE INVENTION

[0012] Hereinafter, embodiments of the link mechanism with a wire harness and the wire harness according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited to these embodiments.

[0013] [Embodiment] One embodiment of the link mechanism with a wire harness and the wire harness according to the present invention will be described based on FIGS. 1 to 12.

[0014] Reference numeral 1 in FIGS. 1 to 8 indicates the link mechanism with a wire harness of the present embodiment.

[0015] For example, in a vehicle such as an automobile, a vehicle equipped with a slide door <510> that can perform a slide operation (a reciprocating movement operation in the slide direction) with respect to the vehicle body is known (FIG. 1). In this vehicle, a link mechanism <10> for reciprocating the slide door <510> in the slide direction with respect to the vehicle body is provided, and the vehicle body side and the slide door <510> side are electrically connected by a wire harness <110> routed along the link mechanism <10> (FIGS. 1 to 8). The link mechanism with a wire harness <1> includes the link mechanism <10> and the wire harness <110> assembled to each other.

[0016] The link mechanism <10> is connected between the vehicle body and, for example, the slide door <510> on the side of the vehicle, and opens and closes the slide door <510> between the fully closed position of the door (FIGS. 1 to 4) and the fully open position of the door (FIGS. 5 to 8) with respect to the vehicle body.

[0017] This link mechanism 10 comprises a vehicle-side arm 20 installed on the vehicle body side, a door-side arm 30 installed on the sliding door 510 side, and a pair of coaxial rotating shafts 40 that rotatably connect one end each of the vehicle-side arm 20 and the door-side arm 30 (Figures 1 to 8). In this link mechanism 10, the vehicle-side arm 20, the door-side arm 30, and the rotating shafts 40 are made of metal materials such as steel or aluminum alloy.

[0018] The vehicle body side arm 20 and the door side arm 30 are each provided with arm bodies 21 and 31 (Figures 1 to 8).

[0019] Each arm body 21, 31 has a pair of main walls 22, 32 that are positioned opposite each other with a vertical gap between them (Figures 1 to 8). The main walls 22, 32 shown here each have a horizontal surface and are formed in the shape of a rectangular flat plate that extends between the vehicle body and the sliding door 510. Each arm body 21, 31 has a closing wall 23, 33 that connects the edges of the pair of main walls 22, 32 along the extending direction and closes the opening between those edges (Figure 1).

[0020] Furthermore, the vehicle body side arm 20 and the door side arm 30 are each provided with a pair of support walls 24, 34 that are positioned opposite each other with a vertical gap between them at one end (Figures 1 to 5, 7 and 8).

[0021] The vehicle-side arm 20 shown here is provided with a protruding piece that projects in a single-piece shape from one end of each of the pair of main walls 22 on the same plane. In the vehicle-side arm 20, each of these protruding pieces is used as a support wall 24 (Figures 1 to 5 and 8).

[0022] Furthermore, the door-side arm 30 shown here includes a support arm member 35 which is molded as a separate component from the arm body 31, and the arm body 31 and the support arm member 35 are joined together, for example by welding, to form a single part (Figures 1 to 8).

[0023] The support arm member 35 has a pair of main walls 36 that are positioned opposite each other with a gap in the vertical direction (Figures 1 to 8). These main walls 36 are formed in the shape of an L-shaped plate with a horizontal surface. The support arm member 35 also has a closing wall 37 that connects the edges of the L-shaped long pieces of the pair of main walls 36 along the extending direction and closes the opening between the edges (Figure 1).

[0024] In this support arm member 35, the arm body 31 is not placed between the L-shaped short pieces of each main wall 36, but rather the L-shaped long pieces of each main wall 36 are joined to the respective main walls 32 of the arm body 31. In this way, in this support arm member 35, each L-shaped short piece is used as a support wall 24. Here, with the extending direction of the L-shaped long piece aligned with the extending direction of the main wall 32, the L-shaped long piece is overlapped and joined to the outer wall surface of the main wall 32.

[0025] In the link mechanism 10, the vertically upward support walls 24 and 34 of the vehicle body side arm 20 and the door side arm 30 are superimposed, and the vertically downward support walls 24 and 34 of the vehicle body side arm 20 and the door side arm 30 are superimposed. Here, the outer surface of each support wall 34 is superimposed (Figures 2 to 5, 7 and 8).

[0026] One rotation axis 40 connects the vertically upward support walls 24 and 34 of the vehicle body side arm 20 and the door side arm 30 so that they can rotate around a vertical axis. The other rotation axis 40 connects the vertically downward support walls 24 and 34 of the vehicle body side arm 20 and the door side arm 30 so that they can rotate around a vertical axis.

[0027] Each of the support walls 24 and 34 has a circular through-hole (not shown) that serves as a bearing for the rotating shaft 40. For example, a rivet member is used for the rotating shaft 40 here. The rotating shaft 40 has disc-shaped locking parts 41 with a diameter larger than the through-holes in the overlapping support walls 24 and 34, which are provided at both ends by riveting or the like (Figures 1 to 8). In this rotating shaft 40, one locking part 41 is positioned facing the outer wall surface of the support wall 24 at one end in the axial direction, and the other locking part 41 is positioned facing the inner wall surface of the support wall 34 at the other end in the axial direction, thereby connecting the overlapping support walls 24 and 34 so that they can rotate freely around the vertical axis.

[0028] The vehicle body side arm 20 and the door side arm 30 are positioned such that when the sliding door 510 is in the fully closed position, the extending direction of their respective pair of main walls 22 and 32 is aligned with the sliding direction of the sliding door 510 (Figures 1 to 4).

[0029] Here, the link mechanism 10 may include a vehicle-side arm 20 as the arm positioned closest to the vehicle body, or it may have another arm closer to the vehicle body than the vehicle-side arm 20. Also, the link mechanism 10 may include a door-side arm 30 as the arm positioned closest to the sliding door 510, or it may have another arm closer to the sliding door 510 than the door-side arm 30.

[0030] The vehicle body-side arm 20 shown here is positioned as close to the vehicle body as possible and fixed to the vehicle body. The link mechanism 10 shown here comprises, in order from the vehicle body side to the sliding door 510 side, the vehicle body-side arm 20 as the first arm, the door-side arm 30 as the second arm, and the third arm 50 (Figure 5). This link mechanism 10 also includes an arm support member 60 fixed to the sliding door 510 (Figure 5).

[0031] In this link mechanism 10, one end of the third arm 50 is rotatably connected to the arm support member 60 via a rotating shaft 71 (Figure 5). The rotating shaft 71 rotatably connects the arm support member 60 and one end of the third arm 50 around a vertical axis. In addition, in this link mechanism 10, the other ends of the door-side arm 30 and the third arm 50 are rotatably connected via a rotating shaft 72 (Figure 5). The rotating shaft 72 rotatably connects the other ends of the door-side arm 30 and the third arm 50 around a vertical axis.

[0032] The wire harness 110 is provided with a harness body 120, which serves as a wiring component for electrically connecting a first electrical connection target 550 installed on the vehicle body and a second electrical connection target 560 installed on the sliding door 510 (Figures 1 to 8). In this harness body 120, multiple electric wires (not shown) are bundled together.

[0033] The first electrical connection target 550 refers to items installed on the vehicle body side, such as a power source (secondary battery, etc.) and electrical components. For example, these vehicle body-side electrical components refer to audio equipment related to the speaker of the sliding door 510, or a drive unit that operates the power seat. On the other hand, the second electrical connection target 560 refers to items installed on the sliding door 510, such as electrical components and switches. For example, these electrical components of the sliding door 510 refer to a drive unit that operates the power window, a speaker, etc. Also, the switches of the sliding door 510 refer to switches for operating the power window, switches for operating the power seat, etc.

[0034] The harness body 120 has a connecting section 121 that runs along the link mechanism 10 between the vehicle body and the sliding door 510 (Figures 1 to 8). For example, the connecting section 121 is provided with an exterior member (not shown) such as a corrugated tube through which multiple electric wires pass inward or a resin tape wrapped around multiple electric wires.

[0035] Furthermore, in this harness body 120, one end of the connecting portion 121 on the vehicle body side (hereinafter referred to as the "vehicle body side end") has another end on the vehicle body side beyond it. And in this harness body 120, the other end of the connecting portion 121 on the sliding door 510 side (hereinafter referred to as the "door side end") has another end on the sliding door 510 side beyond it. Therefore, the harness body 120 has a vehicle body side routing portion 122 routed at the end of the vehicle body side end of the connecting portion 121, and a door side routing portion 123 routed at the end of the door side end of the connecting portion 121 (Figures 1, 2, 4 to 6 and 8).

[0036] The connecting section 121 is passed between the vehicle body and the sliding door 510, through the inside of the vehicle body side arm 20 and the door side arm 30 (Figures 1 to 6 and 8). The vehicle body side wiring section 122 is extended outward from the other end of the vehicle body side arm 20 (Figures 1, 2, 4 to 6 and 8). The door side wiring section 123 is extended outward from in front of the pivot shaft 72 at the other end of the door side arm 30 (Figures 1, 2, 4 to 6 and 8). A notch 32a is formed in the main wall 32 on the other end side of the arm body 31 in front of the pivot shaft 72 (Figures 1, 2, 4 to 6 and 8). The door side wiring section 123 is extended outward from this notch 32a.

[0037] The connecting section 121 is specifically stretched between the vehicle body and the sliding door 510 through the pair of main walls 22, 32 and the pair of support walls 24, 34 in the vehicle body side arm 20 and the door side arm 30, respectively. The wire harness 110 includes a vehicle body side harness support member 130 and a door side harness support member 140 that support this connecting section 121 inside the vehicle body side arm 20 and the door side arm 30, respectively (Figures 1, 2 and 4 to 10). The vehicle body side harness support member 130 and the door side harness support member 140 are molded from, for example, a synthetic resin material.

[0038] The vehicle-side harness support member 130 is fixed inside the arm body 21 of the vehicle-side arm 20. This vehicle-side harness support member 130 is fixed to the arm body 21 of the vehicle-side arm 20 using, for example, a fixing member such as a screw.

[0039] The vehicle-side harness support member 130 supports the vehicle-side end of the connecting portion 121 by lifting it vertically upward and from vertically below. The vehicle-side harness support member 130 is provided with a main body portion 131 through which the harness body 120 is inserted and which supports the vehicle-side end of the connecting portion 121 by lifting it vertically upward and from vertically below (Figures 2, 3, and 9). In the main body portion 131, the connecting portion 121, whose vehicle-side end is supported, is pulled out from inside the arm body 21 toward one end of the vehicle-side arm 20. In addition, in the main body portion 131, the vehicle-side cable routing portion 122 is pulled out from inside the arm body 21 toward the other end of the vehicle-side arm 20.

[0040] For example, the connecting section 121 is equipped with a corrugated tube as an exterior member, which has a bellows section in which annular recesses and annular protrusions are arranged alternately in the axial direction (not shown). The main body 131 shown here is provided with a fitting protrusion 131a that fits concentrically into the annular recess of the corrugated tube, and a fitting recess 131b that fits concentrically into the annular protrusion of the corrugated tube (Figure 9). The fitting protrusion 131a is formed in a semi-circular shape that fits concentrically into the annular recess of the corrugated tube to support the bellows section from vertically below. The fitting recess 131b is also formed in a semi-circular shape that fits concentrically into the annular protrusion of the corrugated tube to support the bellows section from vertically below. In the main body 131, the corrugated tube at the vehicle body side end of the connecting section 121 is fitted into the fitting protrusion 131a and the fitting recess 131b to support the vehicle body side end from below. The vehicle body-side harness support member 130 can restrict the axial position of the connecting portion 121 inside the vehicle body-side arm 20 through the fitting projection 131a and fitting recess 131b.

[0041] After being pulled out from the main body 131, the connecting portion 121 is passed through the space between the pair of support walls 24 and 34 on the vehicle body side arm 20 and the door side arm 30, respectively, and into the door side arm 30.

[0042] Furthermore, the vehicle-side harness support member 130 is provided with protrusions 132 that project vertically upward and vertically downward from the main body portion 131 (Figures 2, 3, and 9). The vertically upward protrusion 132 extends until it abuts against the vertically upward main wall 22 of the vehicle-side arm 20. The vertically downward protrusion 132 extends until it abuts against the vertically downward main wall 22 of the vehicle-side arm 20. Thus, the vehicle-side harness support member 130 is held between its pair of main walls 22.

[0043] Furthermore, the door-side harness support member 140 is fixed inside the arm body 31 of the door-side arm 30. This door-side harness support member 140 is fixed to the arm body 31 of the door-side arm 30 using, for example, a fixing member such as a screw.

[0044] The door-side harness support member 140 supports the door-side end of the connecting portion 121 by lifting it vertically upward and from vertically below. The door-side harness support member 140 is provided with a main body portion 141 through which the harness body 120 is inserted and which supports the door-side end of the connecting portion 121 by lifting it vertically upward and from vertically below (Figures 2 and 10). In the main body portion 141, the connecting portion 121, whose door-side end is supported, is pulled out from inside the arm body 31 toward one end of the door-side arm 30. In other words, the connecting portion 121, which has been routed from the vehicle body side arm 20, passes between the pair of support walls 24 and 34, and then enters the inside of the main body portion 141 of the door-side harness support member 140 by passing inside the door-side arm 30. Furthermore, in this main body 141, the door-side cable routing section 123 is pulled out from inside the arm body 31 toward the other end of the door-side arm 30.

[0045] For example, if the connecting section 121 is equipped with a corrugated tube as an exterior member, the main body 141 shown here is provided with a fitting projection 141a that fits concentrically into the annular recess of the corrugated tube, and a fitting recess 141b that fits concentrically into the annular projection of the corrugated tube (Figure 10). The fitting projection 141a is formed in a semi-circular shape that fits concentrically into the annular recess of the corrugated tube to support the bellows section from vertically below. The fitting recess 141b is also formed in a semi-circular shape that fits concentrically into the annular projection of the corrugated tube to support the bellows section from vertically below. In the main body 141, the corrugated tube at the door-side end of the connecting section 121 is fitted into the fitting projection 141a and the fitting recess 141b to support the door-side end. The door-side harness support member 140 can restrict the axial position of the connecting portion 121 inside the door-side arm 30 through its fitting projection 141a and fitting recess 141b.

[0046] The door-side harness support member 140 shown here is positioned inside the door-side arm 30, closer to the other end (i.e., the side of the rotation axis 72) (Figures 1, 2, 4 to 6, and 8). Here, the door-side harness support member 140 is positioned in front of the notch 32a (i.e., one end of the door-side arm 30 closer to the notch 32a). Therefore, after the door-side cable routing section 123 is pulled out from the main body 141, it is pulled out from the notch 32a to the outside of the door-side arm 30.

[0047] Incidentally, when the sliding door 510 is opened and closed between the fully closed position and the fully open position, the connecting section 121 passes between the pair of rotating shafts 40 at at least one of the following timings: the fully closed position, the fully open position, or during door opening and closing. Therefore, the connecting section 121 is routed between each pair of support walls 24, 34, passing between the pair of rotating shafts 40 at a location away from each of the rotating shafts 40.

[0048] However, the connecting section 121 may sag under its own weight, and there is a risk that it may get caught on the vertically upper end of the other rotating shaft 40 (that is, the vertically upper locking section 41 (hereinafter referred to as "locking section 41A") on the vertically lower rotating shaft 40 (hereinafter referred to as "rotating shaft 40A")) when passing between the pair of rotating shafts 40.

[0049] Therefore, in the wire harness link mechanism 1, a lifting member 150 is provided to lift and support the connecting portion 121 in order to avoid interference between the connecting portion 121 and the rotating shaft 40A (Figures 1 to 4, 6 to 8, 11 and 12). This lifting member 150 lifts the connecting portion 121 vertically upward to a position where it avoids contact with the locking portion 41A of the rotating shaft 40A, and supports it from vertically downward.

[0050] In this example, the lifting member 150 is positioned inside the door-side arm 30. Therefore, the lifting member 150 is interposed between the main wall vertically below the door-side arm 30 (the main wall 32 vertically below the arm body 31 or the main wall 36 vertically below the support arm member 35) and the connecting portion 121, and is provided with a support portion 151 that lifts the connecting portion 121 vertically above the wall surface vertically above the main wall (Figures 2, 3, 6, 7, 11, and 12). The lifting member 150 shown here is interposed between the main wall 36 vertically below the support arm member 35 (hereinafter referred to as "main wall 36A") and the connecting portion 121.

[0051] The lifting member 150 is assembled to the connecting section 121 or the door-side arm 30 on the side of the pair of rotating shafts 40 that is closer to the door-side harness support member 140 inside the door-side arm 30. When the lifting member 150 is assembled to the connecting section 121, for example, it is molded from a synthetic resin material as an annular member that surrounds the connecting section 121 in a ring shape in the circumferential direction. When the lifting member 150 is assembled to the door-side arm 30, for example, it is molded from a synthetic resin material as a plate member that is fixed by being attached to the wall surface vertically above the main wall 36A.

[0052] Here, a lifting member 150, which is assembled to the connecting section 121, is given as an example. This lifting member 150 is formed in an annular shape. In this lifting member 150, the sum of the thickness of the annule and the vertical height at the support section 151 is made greater than the plate thickness of the locking section 41A of the rotating shaft 40A. By adjusting this sum, the lifting member 150 lifts the connecting section 121 vertically upward to a position where it avoids contact between the connecting section 121 and the locking section 41A of the rotating shaft 40A.

[0053] For example, the lifting member 150 is a lifting member 150A that is divided into a first arc section 150a and a second arc section 150b in the vertical direction from the axis of the ring (Figure 11). This lifting member 150A is assembled in a ring shape by sandwiching the connecting section 121 between the first arc section 150a and the second arc section 150b. Here, a rectangular support section 151 is provided on the first arc section 150a.

[0054] The lifting member 150A is provided with a pair of locking mechanisms 152 to maintain the annular shape formed by the assembly of the first arc portion 150a and the second arc portion 150b (Figure 11). The locking mechanism 152 comprises a claw-shaped first engaging portion 152a provided at the circumferential end of the first arc portion 150a, and a second engaging portion 152b provided at the circumferential end of the second arc portion 150b, which hooks onto the first engaging portion 152a in the assembled state (Figure 11).

[0055] Alternatively, for example, as the lifting member 150, a lifting member 150B may be used in which one end in the circumferential direction of the first arc portion 150a and the second arc portion 150b is connected by a living hinge 153 (Figure 12). In this lifting member 150B, the assembled state is maintained by a locking mechanism 152 provided at the other end in the circumferential direction of the first arc portion 150a and the second arc portion 150b.

[0056] The lifting members 150 (150A, 150B) are assembled to a predetermined position on the connecting section 121, for example, by utilizing the corrugated tube provided on the connecting section 121. Thus, the lifting members 150 have a fitting projection 154 that is concentrically fitted into a recess of the corrugated tube to support the bellows section, and a fitting recess 155 that is concentrically fitted into a projection of the corrugated tube to support the bellows section (Figures 11 and 12).

[0057] In this example, when the lifting member 150 is positioned on the door-side arm 30, it is desirable that the vehicle-side harness support member 130 be molded to lift the vehicle-side end of the connecting portion 121 vertically upward to a position that avoids contact between the connecting portion 121 and the locking portion 41A of the rotating shaft 40A, and to support it from vertically downward. For example, in this vehicle-side harness support member 130, the support position of the vehicle-side end of the connecting portion 121 on the main body 131 can be adjusted vertically by adjusting the amount of protrusion of each of the protruding portions 132.

[0058] Furthermore, in this case, it is desirable that the vehicle-side harness support member 130 be positioned between one end and the other end of the vehicle-side arm 20, closer to one end (i.e., the side of the pair of rotating shafts 40) than its center, so that the connecting portion 121 does not sag under its own weight and come into contact with the locking portion 41A of the rotating shaft 40A (Figures 2, 4, and 8). The vehicle-side harness support member 130 shown here is positioned so that even if the connecting portion 121 pulled out from the main body 131 sags under its own weight, the connecting portion 121 will not come into contact with the locking portion 41A of the rotating shaft 40A, as is the case here.

[0059] Incidentally, the lifting member 150 may be positioned inside the vehicle body side arm 20 (not shown). This lifting member 150 is assembled to the connecting portion 121 or the vehicle body side arm 20 on the side of the pair of rotating shafts 40 than the vehicle body side harness support member 130 inside the vehicle body side arm 20, and lifts the connecting portion 121 vertically upward to a position that avoids contact between the connecting portion 121 and the locking portion 41A of the rotating shaft 40A, and supports it from vertically below.

[0060] In this case, the support portion 151 of the lifting member 150 is interposed between the main wall 22 vertically below the vehicle body side arm 20 and the connecting portion 121, lifting the connecting portion 121 vertically above the wall surface of the main wall 22 vertically above it.

[0061] When the lifting member 150 is assembled to the connecting section 121, for example, the annular lifting members 150A and 150B described above are used. When the lifting member 150 is assembled to the vehicle body side arm 20, for example, it is molded from a synthetic resin material as a plate member that is fixed by being attached to the vertically upper wall surface of the vertically lower main wall 22.

[0062] When the lifting member 150 is positioned on the vehicle body side arm 20 in this manner, the door side harness support member 140 may be molded to lift the door side end of the connecting portion 121 vertically upward to a position that avoids contact between the connecting portion 121 and the locking portion 41A of the rotating shaft 40A, and then support it from vertically downward.

[0063] In this case, it is desirable that the door-side harness support member 140 be positioned between one end and the other end of the door-side arm 30, closer to one end (i.e., the side of the pair of rotating shafts 40) than its center, so that the connecting portion 121 does not sag under its own weight and come into contact with the locking portion 41A of the rotating shaft 40A. It is desirable that the door-side harness support member 140 be positioned so that even if the connecting portion 121 pulled out from the main body 141 sags under its own weight, the connecting portion 121 will not come into contact with the locking portion 41A of the rotating shaft 40A, as it is positioned closer to one end of the door-side arm 30. Therefore, in this case, the door-side cable routing portion 123, after being pulled out from the main body 141, is routed through the inside of the arm body 31 to just before the notch 32a, and then pulled out outward from the notch 32a.

[0064] As described above, in this embodiment, the wire harness-equipped link mechanism 1 and wire harness 110 support the connecting portion 121 in a position where the lifting member 150 avoids contact between the connecting portion 121 and the locking portion 41A of the rotating shaft 40A. Therefore, interference between the connecting portion 121 and the rotating shaft 40A can be suppressed at any timing, whether the door is fully closed, fully open, or during door opening and closing. Furthermore, the interference suppression effect between the connecting portion 121 and the rotating shaft 40A can be further enhanced by using the vehicle body-side harness support member 130 or the door-side harness support member 140 in combination with the wire harness-equipped link mechanism 1 and wire harness 110.

[0065] Here, the vehicle body-side harness support member 130 can restrict the axial position of the connecting portion 121 inside the vehicle body-side arm 20 by fitting projection 131a and fitting recess 131b. Similarly, the door-side harness support member 140 can restrict the axial position of the connecting portion 121 inside the door-side arm 30 by fitting projection 141a and fitting recess 141b. In other words, in this wire harness link mechanism 1 and wire harness 110, the length between the vehicle body-side end and the door-side end of the connecting portion 121 can be adjusted by adjusting the support positions of the vehicle body-side end and the door-side end of the connecting portion 121. Therefore, this wire harness link mechanism 1 and wire harness 110 can also suppress interference between the connecting portion 121 and the rotating shaft 40A by adjusting the amount of sagging due to the weight of the connecting portion 121.
