Note that the present invention is not limited to the embodiment. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Fig. 1 to Fig. 9. The embodiment relates to a wiring structure. Fig. 1 is a perspective view of the wiring structure according to the embodiment, Figs. 2 and 3 are plan views of the wiring structure according to the embodiment, Fig. 4 is an exploded perspective view of the wiring structure according to the embodiment, Fig. 5 is an exploded perspective view of a rotating member according to the embodiment, Fig. 6 is a plan view showing the interior of a protector according to the embodiment, Fig. 7 is a front view of the wiring structure according to the embodiment, Fig. 8 is a plan view showing the interior of the protector according to the embodiment, and Fig. 9 is a front view of the wiring structure according to the embodiment.

[0011] As shown in Fig. 1, the wiring structure 1 of this embodiment includes a protector 2, a rotating member 3, and an electric wire W. As shown in Fig. 2 and Fig. 3, the electric wire W connects a vehicle body 110 and a sliding door 120 of a vehicle 100. The electric wire W is connected to a power source such as a battery and a control unit such as an ECU in the vehicle body 110.

[0012] The sliding door 120 slides along a first direction X relative to the vehicle body 110. The first direction X is, for example, the front-to-rear direction of the vehicle 100. The sliding door 120 slides while being guided, for example, by a rail arranged in the vehicle body 110. The sliding door 120 may slide by the operation of a link mechanism that connects the vehicle body 110 and the sliding door 120.

[0013] FIG. 2 is a diagram showing the wiring structure 1 when the sliding door 120 is in the fully closed position. When the sliding door 120 is in the fully closed position, as shown in FIG. 2, the electric wire W extends from the protector 2 in a first direction X. FIG. 3 is a diagram showing the wiring structure 1 when the sliding door 120 is in the fully open position. When the sliding door 120 is in the fully open position, as shown in FIG. 3, the electric wire W extends from the protector 2 in a second direction Y. The second direction Y is, for example, the width direction of the vehicle 100. When the sliding door 120 is in the fully open position, the rotating member 3 protrudes from the protector 2 toward the space 130 on the vehicle body 110 side. In the wiring structure 1 of this embodiment, the rotation angle of the rotating member 3 when the sliding door 120 moves between the fully closed position and the fully open position is greater than 90°.

[0014] The protector 2 is disposed on the sliding door 120 and is held by the sliding door 120. The rotating member 3 is rotatably supported by the protector 2. As shown in FIGS. 2 and 3 , the rotating member 3 rotates in accordance with the change in the extending direction of the electric wire W caused by the movement of the sliding door 120.

[0015] A cylindrical exterior member 5 may be disposed between the rotating member 3 and the vehicle body 110. In this case, the rotating member 3 holds one end 5a of the exterior member 5. The other end of the exterior member 5 is held by a holding member disposed in the vehicle body 110. The electric wires W are inserted into the exterior member 5 and are protected by the exterior member 5.

[0016] As shown in FIG. 4, the protector 2 has a protector body 6 and a cover 7. The protector body 6 and the cover 7 are molded from, for example, insulating synthetic resin. The protector body 6 has a semi-cylindrical shape. The protector body 6 has a wiring path 60 in which the electric wire W is routed. The wiring path 60 is composed of a bottom wall 61, a first side wall 64, and a second side wall 65.

[0017] The protector main body 6 has a first opening 60a and a second opening 60b. The first opening 60a is an opening through which the electric wire W is drawn toward the vehicle body 110. The protector 2 is disposed with the first opening 60a facing the vehicle body 110. The wiring path 60 is connected to the first opening 60a. The wiring path 60 near the first opening 60a has a tapered shape in which the opening width narrows toward the second opening 60b. The first opening 60a is formed so as not to interfere with the rotating member 3 based on the rotation range of the rotating member 3. The second opening 60b is an opening through which the electric wire W is drawn toward the sliding door 120. The illustrated second opening 60b opens upward.

[0018] A through hole 62 that rotatably supports the rotation shaft 83 of the rotation member 3 is provided in the bottom wall 61 of the wiring passage 60. The through hole 62 is disposed near the first opening 60a.

[0019] The cover 7 is a member that engages with the protector body 6 to cover the wiring path 60 from above. The protector body 6 and the cover 7 surround the electric wires W routed in the wiring path 60 and protect the electric wires W. The cover 7 has a recess that rotatably supports the rotation shaft 93 of the rotating member 3. The recess is located at a position facing the through hole 62 of the protector body 6.

[0020] The rotating member 3 has a first member 8 and a second member 9. The first member 8 and the second member 9 are molded from, for example, an insulating synthetic resin. The first member 8 has a bottom wall 80, a first side wall 81, and a second side wall 82. The first side wall 81 and the second side wall 82 are erected from the bottom wall 80. The bottom wall 80, the first side wall 81, and the second side wall 82 form a semi-cylindrical portion having a rectangular cross section. A cylindrical rotating shaft 83 is provided at an end of the bottom wall 80. The rotating shaft 83 is rotatably supported by the through hole 62 of the protector 2.

[0021] The second member 9 has a top wall 90, a first side wall 91, and a second side wall 92. The top wall 90, the first side wall 91, and the second side wall 92 form a semi-cylindrical portion having a rectangular cross section. A cylindrical rotation shaft 93 is provided at the end of the top wall 90. The rotation shaft 93 is rotatably supported by the cover 7 of the protector 2.

[0022] As shown in Fig. 4, the rotating member 3 has a rectangular cylindrical portion 31. The cylindrical portion 31 is formed by a semi-cylindrical portion of the first member 8 and a semi-cylindrical portion of the second member 9. The rotating member 3 is rotatable around rotation axes 83 and 93. When the sliding door 120 opens or closes, the rotating member 3 rotates so as to change the orientation of the cylindrical portion 31, thereby following the electric wire W.

[0023] The rotating member 3 of this embodiment has a shielding wall 32 that shields the electric wires W from the space 130 on the vehicle body 110 side. As shown in FIG. 5 , the shielding wall 32 of this embodiment is provided on a first side wall 81 of the first member 8. The first side wall 81 is one of a pair of side walls 81, 82 that the first member 8 has, and is located on the vehicle body 110 side with respect to the electric wires W when the rotating member 3 is in a predetermined rotation position. The predetermined rotation position is, for example, the rotation position shown in FIGS. 2 and 6 , which is the rotation position of the rotating member 3 when the sliding door 120 is in a fully closed position.

[0024] 6, at a predetermined rotation position, a gap Gp is ​​generated between the first side wall 81 of the rotating member 3 and the first side wall 64 of the protector main body 6. In other words, without the shielding wall 32, the electric wires W would be exposed toward the space 130 on the vehicle body 110 side. In the wiring structure 1 of this embodiment, the electric wires W are shielded by the flexible shielding wall 32. Therefore, according to the wiring structure 1 of this embodiment, the electric wires W are less likely to be visible from the space 130 on the vehicle body 110 side.

[0025] As shown in Fig. 5, the shielding wall 32 extends from an end 81a of the first side wall 81. The end 81a is one of two ends of the first side wall 81 along the path of the electric wire W, and is the end closer to the rotation shaft 83. The shielding wall 32 is flexible and elastically deformable. The thickness of the shielding wall 32 is thinner than the thickness of the first side wall 81. The thickness of the shielding wall 32 is determined, for example, so that the shielding wall 32 can be flexibly deformed while in contact with the first side wall 64 of the protector body 6 when the rotating member 3 rotates.

[0026] The shielding wall 32 is disposed with a gap from the bottom wall 80 and is swingable relative to the bottom wall 80. The shielding wall 32 extends from the first side wall 81 so as to protrude from the edge of the bottom wall 80. The shielding wall 32 in this embodiment has a rectangular flat plate shape. That is, the shielding wall 32 is formed so as to have a flat plate shape when not elastically deformed.

[0027] 6 shows the rotating member 3 housed in the protector 2. The cover 7 of the protector 2 and the second member 9 of the rotating member 3 are omitted from FIG. 6. The rotating member 3 is disposed in the first opening 60a of the protector 2 and is rotatably supported by the protector 2. The rotating member 3 is assembled to the protector 2 such that the tip of the tubular portion 31 protrudes from the first opening 60a of the protector 2. As shown in FIG. 6, when the sliding door 120 is in the fully closed position, the tip of the tubular portion 31 protrudes from the protector 2 along the first direction X.

[0028] The electric wire W is inserted into the rotating member 3 and drawn out from the rotating member 3 toward the wiring path 60. More specifically, the electric wire W is inserted between the first side wall 81 and the second side wall 82 of the first member 8 and is supported by the bottom wall 80. The electric wire W extending from the rotating member 3 is routed in the wiring path 60 and drawn out to the outside of the protector 2 through the second opening 60b. In FIG. 6, the shape of the shielding wall 32 before deformation is shown by a dashed dotted line 32i. The rotating member 3 is housed in the protector main body 6 while deforming the shielding wall 32. When the sliding door 120 is in the fully closed position, the shape of the shielding wall 32 is approximately S-shaped.

[0029] As shown in Fig. 6, the shielding wall 32 is inserted into the wiring path 60 of the protector body 6 and accommodated in the wiring path 60. The shielding wall 32 is inserted into the wiring path 60 in a state in which it is elastically deformed so as to have a curved shape. An intermediate portion 32a of the shielding wall 32 contacts a first side wall 64 of the protector body 6 and is supported by the first side wall 64. An end portion 32b of the shielding wall 32 contacts the electric wire W and is supported by the electric wire W. At this time, the shape of the shielding wall 32 is a substantially S-shape having two curved portions C1 and C2.

[0030] The first curved portion C1 is a curved portion formed between the first side wall 81 and the middle portion 32a, and curves toward the vehicle body 110. Because the first curved portion C1 is curved toward the vehicle body 110, the shielding wall 32 is less likely to interfere with the bottom wall 80.

[0031] The second curved portion C2 is a curved portion formed between the middle portion 32a and the tip portion 32b, and curves toward the side opposite to the vehicle body 110. Since the second curved portion C2 is curved toward the electric wire W, the shielding wall 32 can slide smoothly against the electric wire W when the rotating member 3 rotates.

[0032] 6, when the sliding door 120 is in the fully closed position, the shielding wall 32 is pressed against the first side wall 64 of the protector 2. The shielding wall 32 closes the first opening 60a of the protector 2, and can prevent foreign matter from entering the inside of the protector 2. Since both the middle portion 32a and the tip portion 32b of the shielding wall 32 are supported, the generation of abnormal noise and the like due to vibration of the shielding wall 32 is suppressed.

[0033] 7 is a front view of the protector 2 and the rotating member 3 when the sliding door 120 is in the fully closed position, as viewed from the second direction Y. As shown in FIG. 7, the shielding wall 32 conceals the electric wires W inside the protector 2 from the outside space. The height of the shielding wall 32 is determined so that it can cover the electric wires W from the upper end to the lower end. In addition, the length of the shielding wall 32 is determined so that the electric wires W inside the protector 2 cannot be seen when viewed from the second direction Y.

[0034] More specifically, the length of the shielding wall 32 is set based on the opening width L1 between the end 81a of the rotating member 3 and the first side wall 64 of the protector 2. The opening width L1 is the width of the gap Gp shown in FIG. 6 and is the length in the first direction X from the end 81a of the rotating member 3 to the end 64a of the protector 2. The end 64a is the end of the first side wall 64 of the protector body 6 on the side of the first opening 60a. The length of the shielding wall 32 is greater than the opening width L1.

[0035] The arrow AR1 shown in FIG. 6 indicates the rotation direction of the rotating member 3 when the sliding door 120 opens. The rotation direction of the arrow AR1 is referred to as the "first rotation direction." When the rotating member 3 rotates in the direction of the arrow AR1, the shielding wall 32 is pushed into the wiring passage 60. The sliding direction of the shielding wall 32 at this time is the direction toward the second opening 60b along the first side wall 64. The shielding wall 32 slides against the first side wall 64 and the electric wire W and is inserted into the rear side of the wiring passage 60 while elastically deforming.

[0036] FIG. 8 shows the inside of the protector 2 when the sliding door 120 is in the fully open position. The cover 7 of the protector 2 and the second member 9 of the rotating member 3 are omitted from FIG. 8. When the sliding door 120 is in the fully open position, the electric wire W is curved inside the protector 2. The electric wire W has a first extending portion W1, a second extending portion W2, and a curved portion W3. The first extending portion W1 is a portion that extends in the second direction Y from the protector 2 toward the vehicle body 110. The second extending portion W2 is a portion that extends into the wiring path 60 of the protector 2 along the first direction X. The curved portion W3 is a portion that curves between the first extending portion W1 and the second extending portion W2.

[0037] The shielding wall 32 is accommodated in the space between the first side wall 64 of the protector 2 and the second extending portion W2 of the electric wire W. At this time, the shape of the shielding wall 32 is a gently curved shape that curves toward the electric wire W. In FIG. 8 , a section of the shielding wall 32 from the middle portion 32a to the tip end portion 32b is in contact with the electric wire W. When the sliding door 120 is in the fully open position, the shielding wall 32 may be spaced apart from the first side wall 64.

[0038] 6 and 8, the shielding wall 32 deforms in response to the rotation of the rotating member 3. When the sliding door 120 slides from the fully closed position to the fully open position, the shielding wall 32 deforms from the approximate S-shape shown in FIG. 6 to the approximate arch-shape shown in FIG. 8. Conversely, when the sliding door 120 slides from the fully open position to the fully closed position, the shielding wall 32 deforms from the approximate arch-shape shown in FIG. 8 to the approximate S-shape shown in FIG. 6. When the sliding door 120 moves, the shielding wall 32 deforms in response to the rotation of the rotating member 3 while being pressed against the electric wires W. In other words, the shielding wall 32 deforms in response to the rotation of the rotating member 3 while being supported by at least the electric wires W. That is, in the wiring structure 1 of this embodiment, the shape of the shielding wall 32 is controlled by the electric wires W.

[0039] 8, when the sliding door 120 is in the fully open position, both the middle portion 32a and the tip portion 32b of the shielding wall 32 are supported by the electric wire W. Therefore, the generation of abnormal noises and the like due to vibration of the shielding wall 32 is suppressed.

[0040] When the sliding door 120 is in the fully open position, the tubular portion 31 of the rotating member 3 shields the electric wires W from the space 130 on the vehicle body 110 side. In addition, the tubular portion 31 is located close to the end 64a of the first side wall 64, and can prevent foreign matter from entering the protector 2.

[0041] 9 is a front view of the protector 2 and the rotating member 3 when the sliding door 120 is in the fully open position, as viewed from the space 130 on the vehicle body 110 side. As shown in FIG. 9, the rotating member 3 covers and conceals the electric wires W inside the protector 2.

[0042] When the sliding door 120 rotates from the fully open position to the fully closed position, the rotational member 3 rotates in the direction indicated by the arrow AR2 in FIG. 8. The rotational direction of the arrow AR2 is referred to as the "second rotational direction." When the rotational member 3 rotates in the second rotational direction, the shielding wall 32 slides in conjunction with the rotation of the rotational member 3. The movement direction of the shielding wall 32 at this time is a direction away from the second opening 60b along the first direction X. The shielding wall 32 moves in conjunction with the rotation of the rotational member 3 while covering and concealing the electric wires W inside the protector 2.

[0043] In this way, the wiring structure 1 of this embodiment is configured so that the electric wires W inside the protector 2 are not visible from the side of the vehicle body 110 when the sliding door 120 is in the fully closed position, the fully open position, and while the sliding door 120 is moving. Therefore, the wiring structure 1 of this embodiment can prevent the electric wires W from being visually recognized by the user, which would otherwise cause a deterioration in appearance.

[0044] As described above, the wiring structure 1 of this embodiment has the electric wire W, the protector 2, and the rotating member 3. The electric wire W connects the vehicle body 110 of the vehicle 100 to the sliding door 120 of the vehicle 100. The protector 2 is disposed on the sliding door 120. The protector 2 has a first opening 60a that opens toward the vehicle body 110, and a wiring path 60 that accommodates the electric wire W. The rotating member 3 is a cylindrical member that is disposed in the first opening 60a and is rotatably supported by the protector 2.

[0045] The electric wire W is inserted into the rotating member 3 and drawn out from the rotating member 3 toward the wiring path 60. The rotating member 3 has a flexible shielding wall 32 that shields the electric wire W from the space 130 on the vehicle body 110 side. The shielding wall 32 is inserted into the wiring path 60 and shields the electric wire W while deforming in response to the rotation of the rotating member 3. The wiring structure 1 of this embodiment can achieve the effect that the electric wire W is difficult to see from the space 130 on the vehicle body 110 side.

[0046] The rotating member 3 of this embodiment has a bottom wall 80 that supports the electric wire W, and a pair of side walls 81, 82 that stand upright from the bottom wall 80. The electric wire W is inserted between the pair of side walls 81, 82. The shielding wall 32 extends from an end of the first side wall 81 so as to follow the electric wire W. Because the shielding wall 32 is integrated with the first side wall 81, the electric wire W is effectively shielded. Furthermore, because the shielding wall 32 is part of the rotating member 3, it is possible to shield the electric wire W without increasing the number of parts.

[0047] The thickness of the shielding wall 32 in this embodiment is thinner than the thickness of the first side wall 81. Therefore, the shielding wall 32 formed to be thin can flexibly deform in response to the rotation of the rotary member 3.

[0048] The shielding wall 32 may be provided on the second member 9 instead of the first member 8. In this case, the shielding wall 32 may be formed integrally with the first side wall 91 of the second member 9. The shielding wall 32 is preferably formed to be thinner than the first side wall 91.

[0049] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
