[0041] [Implementation Method]

Fig.10 express Figure 1 XX section.

[0043] Figure 1 The wiring structure 1 shown is mounted on a vehicle 100. The exemplary vehicle 100 is a car having a power source such as an engine and a motor. Figures 1 to 3 As shown, the wiring structure 1 of the present embodiment includes a first protector 2, a holding member 3, an exterior member 4, a limiting member 5, a second protector 6, a rotating member 7, and an electric wire W. The electric wire W is laid between 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, a control unit, etc. in the vehicle body 110. The electric wire W is connected to a device of the sliding door 120 in the sliding door 120.

[0044] The sliding door 120 slides relative to the vehicle body 110 along a first direction X. The first direction X is, for example, the front-rear direction of the vehicle 100. The sliding door 120 slides, for example, while being guided by a rail disposed on the vehicle body 110. The sliding door 120 may also slide by the operation of a link mechanism connecting the vehicle body 110 and the sliding door 120.

[0045] exist Figure 2 In FIG. 1 , the second protector 6 and the exterior member 4 when the sliding door 120 is in the fully closed position are depicted by solid lines. The second protector 6 and the exterior member 4 when the sliding door 120 is in the fully opened position are depicted by single-dot chain lines.

[0046] The first protector 2 is a protector disposed on the vehicle body 110. The second protector 6 is a protector disposed on the sliding door 120, and moves in the first direction X together with the sliding door 120. The rotating member 7 is supported by the second protector 6 so as to be rotatable. The exterior member 4 is a member that protects the electric wire W. The exterior member 4 extends from the first protector 2 to the second protector 6. The exterior member 4 is a flexible cylindrical member that deforms following the movement of the sliding door 120.

[0047] like Figure 3 As shown in FIG. 1 , the limiting member 5 is inserted into the outer member 4. The limiting member 5 is a member that limits the bending shape of the outer member 4. The wiring structure 1 of this embodiment is configured so that the limiting member 5 is not easily damaged when the outer member 4 is stepped on by a user. Figure 3 As shown, the first end portion 41 of the exterior member 4 is held by the spherical holding member 3. The first protector 2 supports the holding member 3 in a rotatable manner.

[0048] When the exterior member 4 is stepped on by a user, the holding member 3 rotates so that the load is received by the exterior member 4 and the wider surface of the restriction member 5. Thus, the occurrence of stress concentration in the restriction member 5 is suppressed.

[0049] The exterior member 4 of this embodiment is a member called a bellows. The exterior member 4 is flexible and can be bent and deformed between the first protector 2 and the second protector 6. The exterior member 4 is molded from, for example, an insulating synthetic resin. Figure 3 As shown, the exterior member 4 has a first end 41 and a second end 42. The first end 41 is an end on the vehicle body 110 side. The first end 41 is held by the holding member 3 and supported by the first protector 2. The second end 42 is an end on the sliding door 120 side. The second end 42 is held by the rotating member 7 disposed on the sliding door 120.

[0050] like Figure 4As shown, the cross-sectional shape of the outer casing 4 is a shape having a long side direction LD and a short side direction SD. The cross-sectional shape of the outer casing 4 of this embodiment is an oval shape. That is, the cross-sectional shape of the outer casing 4 has arc portions 4a at both ends in the long side direction LD. The cross-sectional shape of the outer casing 4 may also have a straight portion 4b between the two arc portions 4a.

[0051] The exterior member 4 is arranged so that the longitudinal direction LD is along the vehicle vertical direction. The rotating member 7 of the second protector 6 holds the second end 42 of the exterior member 4 in a manner that does not allow the longitudinal direction LD to be tilted relative to the vehicle vertical direction. On the other hand, the first protector 2 supports the spherical holding member 3 in a manner that allows the longitudinal direction LD to be tilted relative to the vehicle vertical direction.

[0052] When the user steps on the exterior member 4, Figure 4 The external force FV in the longitudinal direction LD shown in the figure acts on the outer member 4. Since the cross-sectional shape of the outer member 4 is a longitudinal shape, a moment M1 is generated in the outer member 4 to cause the outer member 4 to fall sideways. Due to the moment M1, the outer member 4 and the restricting member 5 accommodated in the outer member 4 are twisted and deformed so that the stepped part falls over. As a result, as shown in FIG. Fig.11 As shown, the exterior member 4 and the limiting member 5 can receive the external force FV with the wide surface. Therefore, the wiring structure 1 of the present embodiment can suppress the stress concentration in the limiting member 5.

[0053] like Figure 5 As shown, the limiting member 5 has a flexible plate-like main body 53 and a plurality of block portions 54. The limiting member 5 is molded of, for example, an insulating synthetic resin. The main body 53 is a portion extending along the wire W, and has a length equivalent to that of the outer member 4. Therefore, the limiting member 5 extends from the first end 41 to the second end 42 of the outer member 4. The main body 53 is in the shape of an elongated rectangle.

[0054] The block portion 54 is arranged at the edge portion 53a in the width direction of the main body 53. The exemplary limiting member 5 has a plurality of block portions 54 at two edges 53a in the width direction of the main body 53. The block portion 54 is erected from the edge portion 53a of the main body 53 toward a direction orthogonal to the main body 53. At each edge portion 53a, a plurality of block portions 54 are arranged in the extending direction of the main body 53. The block portion 54 has a contact portion 54a and a base portion 54b. The contact portion 54a is a roughly rectangular sheet portion. The contact portion 54a is a portion that limits the curved shape of the main body 53 by contacting with the adjacent contact portion 54a. The base portion 54b is a portion that connects the contact portion 54a to the edge portion 53a of the main body 53. The length of the base portion 54b in the arrangement direction of the block portion 54 is shorter than the length of the contact portion 54a.

[0055] The restricting member 5 has a first end 51 and a second end 52. The first end 51 is one end of the restricting member 5 in the longitudinal direction and is disposed on the vehicle body 110 side. The second end 52 is the other end of the restricting member 5 in the longitudinal direction and is disposed on the sliding door 120 side.

[0056] When the first force F1 in the bending direction acts on the limiting member 5, the abutting portions 54a of the adjacent blocks 54 abut against each other, limiting the bending shape of the main body 53. The blocks 54 resist the first force F1 and extend the main body 53 substantially in a straight line. In addition, the blocks 54 near the first end 51 of the limiting member 5 allow the main body 53 to be slightly bent and deformed by the first force F1. That is, the limiting member 5 is configured to form a gently curved portion 56 near the first end 51 when the first force F1 acts.

[0057] When the second force F2 in the bending direction acts on the limiting member 5, the adjacent block portions 54 are separated. The block portions 54 do not limit the deformation of the main body 53, and allow the main body 53 to be freely bent and deformed. Therefore, the limiting member 5 is configured to limit the bending deformation of the exterior member 4 caused by the first force F1, and allow the bending deformation of the exterior member 4 caused by the second force F2.

[0058] The first end portion 51 is provided with a held portion 55 held by the holding member 3. The held portion 55 is substantially U-shaped when viewed from the front. The held portion 55 includes a linear piece 55a connected to the end of the main body 53 and two linear pieces 55b connected to the ends of the block portion 54.

[0059] The holding member 3 is a member that holds the first end portion 41 of the exterior member 4 and the first end portion 51 of the restricting member 5. The holding member 3 of this embodiment is substantially spherical in shape. Figure 6 As shown, the holding member 3 includes a first member 31 and a second member 32. The first member 31 and the second member 32 are molded of, for example, insulating synthetic resin.

[0060] The first component 31 and the second component 32 each have a hemispherical outer peripheral surface. The first component 31 and the second component 32 of the present embodiment are components of the same shape. The first component 31 and the second component 32 have a first engaging portion 33, a second engaging portion 34, a first retaining portion 35, and a second retaining portion 36. The first retaining portion 35 retains the first end portion 41 of the outer component 4. The first retaining portion 35 is a groove portion having a substantially U-shaped cross-sectional shape. The first retaining portion 35 has a plurality of ribs 35a. The ribs 35a engage with an annular recess provided on the outer side surface of the outer component 4 to lock the first end portion 41.

[0061] The second holding portion 36 holds the held portion 55 of the restricting member 5. The held portion 55 is exposed to the outside from the first end portion 41 of the exterior member 4. The second holding portion 36 has a groove into which the piece 55b of the held portion 55 fits.

[0062] The first engaging portion 33 and the second engaging portion 34 are configured to engage with each other. The first engaging portion 33 is a claw provided on the side surfaces of the first member 31 and the second member 32. The second engaging portion 34 is a frame-shaped piece that is locked by the first engaging portion 33.

[0063] The first component 31 and the second component 32 are engaged along the longitudinal direction LD of the exterior component 4. At this time, the first holding portion 35 of the first component 31 and the first holding portion 35 of the second component 32 clamp the first end portion 41 of the exterior component 4 and hold the first end portion 41. The two first holding portions 35 hold the first end portion 41 in a manner that the first end portion 41 cannot rotate relative to the holding component 3. That is, the holding component 3 holds the first end portion 41 in a manner that the first component 31 and the second component 32 are always opposed to each other in the longitudinal direction LD.

[0064] In addition, the second holding portion 36 of the first member 31 and the second holding portion 36 of the second member 32 sandwich the held portion 55 of the limiting member 5 and hold the held portion 55. The first member 31 and the second member 32 hold the limiting member 5 in a manner that does not rotate relative to the held portion 55 by fitting the grooves of the second holding portion 36 with the held portion 55. The first member 31 and the second member 32 have an opening 37. The electric wire W is led out of the holding member 3 from the opening 37.

[0065] like Figure 3 As shown, the first protector 2 has a protector body 21 and a cover 22. The protector body 21 and the cover 22 are molded of, for example, insulating synthetic resin. The protector body 21 has a wiring path 23 and a support portion 24. The wiring path 23 is a path for laying the electric wires W drawn from the holding member 3. The support portion 24 supports the holding member 3 so that it can rotate.

[0066] like Figure 7 As shown, the support portion 24 is arranged at the end of the sliding door 120 side in the wiring path 23. The support portion 24 has: a pair of ribs 25, which have an arc-shaped support surface; and a connecting rib 26, which has an arc-shaped support surface. The support portion 24 is configured to form a storage chamber for storing the holding component 3 and to allow the holding component 3 to rotate inside the storage chamber. The pair of ribs 25 are arranged in parallel with a gap. The connecting rib 26 is orthogonal to the rib 25 and connected to the two ribs 25. The support portion 24 supports the holding component 3 so that it can rotate using the ribs 25 and the connecting ribs 26.

[0067] The cover 22 is a component that engages with the protector body 21 and covers the wiring path 23. Figure 8 As shown, the cover 22 has a support portion 27 corresponding to the support portion 24 of the protector body 21. The support portion 27 has a pair of ribs 28, and the pair of ribs 28 have arc-shaped support surfaces. The pair of ribs 28 are arranged in parallel with a gap. The support portion 27 is combined with the support portion 24 of the protector body 21 to form a storage chamber for storing the holding component 3.

[0068] like Fig. 9 As shown, the rotating member 7 is a cylindrical member. The rotating member 7 is molded of, for example, an insulating synthetic resin. The rotating member 7 has a first shaft portion 71, a second shaft portion 72, and a cylindrical portion 73. The cylindrical portion 73 has a cylindrical shape and holds the second end portion 42 of the exterior member 4. In addition, the second end portion 52 of the limiting member 5 is located inside the second end portion 42. Therefore, the cylindrical portion 73 holds the second end portion 42 of the exterior member 4 and the second end portion 52 of the limiting member 5.

[0069] The first shaft portion 71 and the second shaft portion 72 are rotatably supported by the second protector 6. The first shaft portion 71 and the second shaft portion 72 are coaxially arranged. The first shaft portion 71 protrudes upward from the end of the barrel portion 73. The first shaft portion 71 has a cylindrical shape and is connected to the barrel portion 73. The wire W is led out from the exterior member 4 to the sliding door 120 via the first shaft portion 71. The second shaft portion 72 protrudes downward from the end of the barrel portion 73.

[0070] The cylinder 73 holds the exterior member 4 and the restricting member 5 in such a manner that the longitudinal direction LD of the exterior member 4 is along the axial direction of the shaft portions 71 and 72. The rotating member 7 is supported by the second protector 6 in such a manner that the longitudinal direction LD is along the vehicle vertical direction Z. The second protector 6 supports the shaft portions 71 and 72 in such a manner that the central axis CX of the shaft portions 71 and 72 is along the vehicle vertical direction Z. That is, the rotating member 7 is supported so as to be rotatable with the axis in the vehicle vertical direction Z as the rotation center.

[0071] The rotating member 7 holds the second end portion 42 so that the longitudinal direction LD is not inclined with respect to the vehicle vertical direction Z. That is, when the exterior member 4 and the restricting member 5 are temporarily twisted and deformed by the external force FV, the rotating member 7 can restore the exterior member 4 and the restricting member 5 to their original postures.

[0072] Fig.10 Shown in Figure 1 In addition, Fig.10 In order to show the internal state of the first protector 2, the cover 22 is omitted. Fig.10As shown, the restricting member 5 and the wire W are inserted into the exterior member 4. The restricting member 5 is inserted into the exterior member 4 with the main body 53 along the longitudinal direction LD of the exterior member 4. The block portions 54 of the restricting member 5 face each other in the longitudinal direction LD.

[0073] The exterior member 4 and the limiting member 5 are arranged between the first protector 2 and the second protector 6 in such a manner that the longitudinal direction LD is along the vehicle vertical direction Z. When a user steps on the exterior member 4, an external force FV toward the lower side in the vehicle vertical direction Z acts on the exterior member 4. As a result, a moment M1 acts on the exterior member 4 at the stepped portion. The retaining member 3 rotates inside the first protector 2, thereby allowing deformation of the exterior member 4 and the limiting member 5 caused by the moment M1.

[0074] exist Fig.11 , the outer casing 4 and the limiting component 5 are shown after being deformed by the moment M1. The outer casing 4 and the limiting component 5 are deformed in such a way that the long side direction LD of the part receiving the external force FV is along the horizontal direction. Therefore, the external force FV acts on the limiting component 5 along the plate thickness direction of the main body 53. As a result, the limiting component 5 is less likely to be damaged than when the external force FV acts along the long side direction LD. When the limiting component 5 is subjected to the external force FV along the long side direction LD, stress concentration is likely to occur at the edge 53a of the main body 53. In contrast, if the external force FV is along the thickness direction of the main body 53, stress concentration is less likely to occur at the edge 53a. Therefore, the wiring structure 1 of the present embodiment can improve the durability of the limiting component 5.

[0075] When the external force FV does not act on the exterior member 4, the exterior member 4 and the restricting member 5 return to their original positions. Fig.10 As shown in the figure. Fig. 9 As described above, the rotating member 7 disposed in the slide door 120 holds the exterior member 4 and the restricting member 5 so that the longitudinal direction LD is along the vehicle vertical direction Z. Therefore, the exterior member 4 and the restricting member 5 can return to their original postures by their respective elastic restoring forces.

[0076] In addition, the opening and closing action of the sliding door 120 can promote the posture restoration of the exterior member 4 and the restricting member 5. Figure 2 As shown, the direction of the bending of the exterior member 4 changes according to the movement of the sliding door 120. When the sliding door 120 is in the fully closed position, a bending portion 43 is formed on the exterior member 4. When the sliding door 120 is in the fully opened position, a bending portion 44 is formed on the exterior member 4. The two bending portions 43 and 44 are bent in opposite directions to each other. By deforming the exterior member 4 in this way, the posture of the exterior member 4 is corrected in such a manner that the long side direction LD is along the vehicle vertical direction Z.

[0077] The restricting member 5 restricts the bending shape of the exterior member 4, thereby correcting the torsion of the exterior member 4. The restricting member 5 corrects the torsion of the exterior member 4 so that the longitudinal direction LD is along the vehicle vertical direction Z by making adjacent block portions 54 abut against each other.

[0078] In addition, the outer casing 4 and the limiting member 5 may be bent downward by being stepped on by a user. In this case, the bending is eliminated by utilizing the rigidity of the outer casing 4 and the wire W. In addition, the rotating member 7 restricts the posture of the second ends 42 and 52 of the outer casing 4 and the limiting member 5, thereby promoting elimination of the bending.

[0079] As described above, the wiring structure of the present embodiment includes a cylindrical outer member 4 through which the electric wire W and the power supply line W are inserted, a limiting member 5, a retaining member 3, a first protector 2, and a cylindrical rotating member 7. The electric wire W is laid between the vehicle body 110 and the sliding door 120 of the vehicle 100. The outer member 4 includes a first end 41 as an end on the vehicle body 110 side and a second end 42 as an end on the sliding door 120 side. The limiting member 5 is inserted into the outer member 4 to limit the bending shape of the outer member 4. The retaining member 3 is a spherical member that retains the first end 41 of the outer member 4. The first protector 2 is arranged on the vehicle body 110 and supports the retaining member 3 so that it can rotate. The rotating member 7 is arranged on the sliding door 120 and is supported so that it can rotate with the axis line in the vehicle up-down direction Z as the rotation center.

[0080] The limiting component 5 has a plate-like main body 53 and a plurality of blocks 54. The main body 53 is flexible and extends along the wire W. The plurality of blocks 54 are arranged at the edge 53a of the main body 53 in the width direction and are arranged in the extension direction of the main body 53. The limiting component 5 limits the bending shape of the main body 53 by making adjacent blocks 54 abut. The cross-sectional shape of the outer casing 4 is a shape having a long side direction LD and a short side direction SD. The limiting component 5 is inserted into the outer casing 4 in such a manner that the width direction of the main body 53 is along the long side direction LD. In the wiring structure 1 of the present embodiment, when an external force FV along the long side direction LD acts on the outer casing 4, the outer casing 4 and the limiting component 5 can be deformed in such a manner that they receive the external force FV in the short side direction SD. Therefore, the wiring structure 1 of the present embodiment can suppress the occurrence of stress concentration in the limiting component 5.

[0081] The rotating member 7 has a cylindrical portion 73 that holds the second end portion 42 of the exterior member 4. The limiting member 5 extends from the first end portion 41 of the exterior member 4 to the second end portion 42. The cylindrical portion 73 holds the second end portion 42 in such a manner that the longitudinal direction LD of the cross-sectional shape of the exterior member 4 at the second end portion 42 is along the vehicle up-down direction Z. The rotating member 7 of the present embodiment can return the exterior member 4 and the limiting member 5 that have been deformed by the external force FV to their original positions.

[0082] The cross-sectional shape of the exterior member 4 of the present embodiment is an oval shape with the direction of the main body 53 of the limiting member 5 as the major axis direction. Therefore, when an external force FV in the longitudinal direction LD acts, a moment M1 easily acts on the exterior member 4 and the limiting member 5 .

[0083] The restricting member 5 of this embodiment has a held portion 55 provided at the end portion on the vehicle body 110 side. The holding member 3 holds the held portion 55 so that the holding member 3 does not rotate relative to the restricting member 5. Thus, relative twisting between the exterior member 4 and the restricting member 5 is less likely to occur.

[0084] If the cross-sectional shape of the exterior member 4 has a longitudinal direction LD, when the external force FV acts, the exterior member 4 and the restricting member 5 are easily subjected to the external force FV at the wider portions.

[0085] The holding member 3 may hold the limiting member 5 via the exterior member 4. In this case, the held portion 55 of the limiting member 5 may be disposed inside the exterior member 4. The held portion 55 may be, for example, an oval shape corresponding to the shape of the exterior member 4.

[0086] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
