DETAILED DESCRIPTION OF THE INVENTION

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring structure of the wire harness of the present disclosure is as follows.

[0011] (1) A wiring structure for a wire harness, comprising: an instrument panel; a reinforcement disposed inside the instrument panel; an intermediate base provided between the instrument panel and the reinforcement; and a wire harness routed along the intermediate base.

[0012] According to the wiring structure of the wire harness of (1), wiring the wire harness from the passenger compartment is easier when the wire harness is routed along the intermediate base located between the instrument panel and the reinforcement than when the wire harness is routed along the reinforcement. In addition, the portion of the wire harness routed along the intermediate base can be hidden from the passenger compartment by the instrument panel. As a result, it is possible to easily add a wire harness to a vehicle and minimize exposure of the added wire harness to the passenger compartment.

[0013] (2) In the wiring structure of (1), the intermediate base may be provided closer to the instrument panel than the reinforcement, thereby making it easier to access the intermediate base from inside the vehicle.

[0014] (3) In the wiring structure of (2), the intermediate base may be formed in a plate shape and provided on the back side of a part of the instrument panel so as to face the instrument panel, so that when the wire harness is routed along the intermediate base, the wire harness is routed so as to also follow the instrument panel.

[0015] (4) In the wiring harness routing structure of (3), a portion of the instrument panel that covers the intermediate base may be detachable from another portion, thereby making it possible to easily route the wire harness to the intermediate base after removing the instrument panel.

[0016] (5) In the wiring structure of any one of (1) to (4), the intermediate base may have a first extending portion extending along the left-right direction of the vehicle and a second extending portion extending from a part of the first extending portion in the front-rear direction of the vehicle, thereby facilitating wiring of the wire harness along the left-right direction and the front-rear direction of the vehicle.

[0017] (6) In the wiring structure of (5), the first extending portion may extend from a region in front of the driver's seat to a region in front of the passenger seat, which makes it easy to route the wiring harness across the entire left-right direction of the vehicle.

[0018] (7) In the wiring structure of (5) or (6), the second extending portion may be partially provided in the area in front of the passenger seat, which makes it easier to connect the end of the wire harness on the passenger seat side.

[0019] (8) In the wiring structure of any one of (1) to (7), the intermediate base may have a plurality of holes, and the wire harness may be fixed by selectively using some of the plurality of holes. This makes it easy to fix any position of the wire harness to the intermediate base.

[0020] (9) In the wiring structure of any one of (1) to (8), a groove may be formed in the intermediate base, and the wire harness may be accommodated in the groove. This makes it easy to route the wire harness in the intermediate base.

[0021] (10) In the wiring structure of any one of (1) to (9), the intermediate base may be fixed to the instrument panel, thereby making it possible to provide the intermediate base on the instrument panel.

[0022] [Details of the embodiments of the present disclosure] Specific examples of the wiring structure of the wire harness of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0023] [Embodiment 1] The wiring structure of the wire harness according to the first embodiment will be described below. Fig. 1 is a plan view showing the wiring structure 30 of the wire harness according to the first embodiment. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is an exploded perspective view showing the wiring structure 30 of the wire harness. Fig. 4 is a plan view showing a state in which a part of the instrument panel 11 is removed.

[0024] The wiring structure 30 for a wire harness is configured to route a wire harness 50 between an instrument panel 11 and a reinforcement 20 in a vehicle 10. The vehicle 10 is, for example, an automobile. The structure of the portion of the vehicle 10 where the wire harness 50 is routed will be described first.

[0025] The instrument panel 11 is located in front of the driver's seat 17 and the passenger seat 18. The instrument panel 11 is an interior component having a surface exposed to the passenger compartment. Instruments 15 such as a speedometer are incorporated into the instrument panel 11. A steering wheel 16 is provided on the instrument panel 11 so as to face rearward relative to the forward movement of the vehicle 10. The steering wheel 16 is supported by a reinforcement 20 via a steering column. A floor 19 extends below and behind the instrument panel 11. The driver's seat 17 and passenger seat 18 are provided on the floor 19.

[0026] The instrument panel 11 is made of resin or the like. The instrument panel 11 includes an upper panel 12 and a lower panel 13. The upper panel 12 is provided in the front region of the instrument panel 11 in an orientation facing upward. The lower panel 13 is connected to the rear edge of the upper panel 12. The lower panel 13 is provided in the rear region of the instrument panel 11 in an orientation facing rearward. The lower panel 13 is oriented closer to the direction of gravity than the upper panel 12. The upper panel 12 and lower panel 13 are connected at an angle or a curve.

[0027] The reinforcement 20 is disposed inside the instrument panel 11 (closer to the vehicle cabin than the instrument panel 11). The reinforcement 20 is an elongated member formed of metal or the like. The reinforcement 20 is formed, for example, in a rod shape such as a cylindrical shape. The reinforcement 20 extends in the left-right direction of the vehicle 10. One end of the reinforcement 20 in the longitudinal direction is connected to the left side wall of the vehicle body, and the other end is connected to the right side wall.

[0028] The wiring structure 30 for the wire harness includes, in addition to the above-mentioned instrument panel 11 and reinforcement 20, an intermediate base 40 and a wire harness 50. The intermediate base 40 is provided between the instrument panel 11 and the reinforcement 20. The wire harness 50 is routed along the intermediate base 40.

[0029] The intermediate base 40 is provided at a position closer to the instrument panel 11 than the reinforcement 20. The intermediate base 40 is formed in a plate shape that extends along the instrument panel 11. Here, the intermediate base 40 is provided on the back side of a portion of the instrument panel 11, facing the instrument panel 11.

[0030] A portion of the instrument panel 11 that covers the intermediate base 40 is detachably attached to the other portion. The intermediate base 40 faces the rear side of one of the upper panels 12A, and the upper panel 12A is detachable separately from the other upper panel 12B and the lower panel 13.

[0031] Here, the intermediate base 40 has a first extending portion 41 and a second extending portion 42. The first extending portion 41 extends along the left-right direction of the vehicle 10. The first extending portion 41 extends from the area in front of the driver's seat 17 to the area in front of the passenger seat 18. The second extending portion 42 extends from a part of the first extending portion 41 in the front-to-rear direction of the vehicle 10 (here, rearward). The second extending portion 42 is partially provided in the area in front of the passenger seat 18.

[0032] However, the shape of the intermediate base 40 is arbitrary. For example, either the first extension portion 41 or the second extension portion 42 may be omitted. For example, the second extension portion may be provided in the area in front of the driver's seat or in the instrument area. For example, the intermediate base may be rectangular in plan view. For example, the intermediate base may be square with the same length in the vehicle longitudinal direction and the vehicle lateral direction, or rectangular with one length longer in the vehicle longitudinal direction and the vehicle lateral direction than the other. The range in which the intermediate base is provided is not particularly limited and can be appropriately set along each of the vehicle longitudinal direction and the vehicle lateral direction. The intermediate base may be provided over the entire upper panel 12 along the vehicle longitudinal direction or the vehicle lateral direction, or may be provided in a portion of the upper panel 12.

[0033] Here, the intermediate base 40 includes a plurality of (here, five) plate-shaped members 43. Of the five plate-shaped members 43, three plate-shaped members 43A, 43B, and 43C form the first extending portion 41, and the remaining two plate-shaped members 43D and 43E form the second extending portion 42. Each plate-shaped member 43 may have enough rigidity to maintain its plate shape along the instrument panel 11. The first extending portion 41 may be formed of a single plate-shaped member. The second extending portion 42 may be formed of a single plate-shaped member. The intermediate base 40 including the first extending portion 41 and the second extending portion 42 may be formed of a single plate-shaped member.

[0034] A plurality of holes 44 are formed in the intermediate base 40. Here, a plurality of holes 44 are formed in each plate-like member 43. The wire harness 50 is fixed using selectively some of the plurality of holes 44. Here, the plurality of holes 44 include a first hole 44A and a second hole 44B that are different in shape from each other. The first hole 44A is a circular hole, and the second hole 44B is a rectangular hole. The second hole 44B is larger than the first hole 44A. The first hole 44A and the second hole 44B are aligned in the left-right direction and the front-rear direction of the vehicle 10. The first hole 44A is formed at a position corresponding to the four corners of the second hole 44B. One second hole 44B is surrounded by four first holes 44A. Some of the first holes 44A are surrounded by four second holes 44B.

[0035] The intermediate base 40 is fixed to the instrument panel 11. Here, the instrument panel 11 has a support frame 14 that supports an upper panel 12B and a lower panel 13. The intermediate base 40 is fixed to the support frame 14. The upper panel 12A that covers the intermediate base 40 is supported by the intermediate base 40. The upper panel 12A may also be supported by the support frame 14 without the intermediate base 40.

[0036] Here, the mounting manner of the upper panel 12B and the lower panel 13 to the support frame 14, the mounting manner of the intermediate base 40 to the support frame 14, and the mounting manner of the upper panel 12A to the intermediate base 40 are all the same. Such mounting manners are not particularly limited and can be set as appropriate. Here, a structure in which the convex portion CV fits into the concave portion CC is used as such mounting manner. Therefore, the intermediate base 40 is provided with the convex portion CV or the concave portion CC (here, the convex portion CV) used for fastening to the support frame 14, and the convex portion CV or the concave portion CC (here, the concave portion CC) used for fastening to the upper panel 12A. However, the mounting manner of the upper panel 12B and the lower panel 13 to the support frame 14, the mounting manner of the intermediate base 40 to the support frame 14, and the mounting manner of the upper panel 12A to the intermediate base 40 may be different from each other.

[0037] The intermediate base 40 may be attached to a member around the instrument panel 11, such as the reinforcement 20 or a portion of the vehicle body that supports the reinforcement 20. The intermediate base 40 may be attached to the instrument panel 11 or a member around it by a hooking structure such as a clip or a locking structure.

[0038] The wire harness 50 is a wiring member that connects electrical components mounted on the vehicle 10. The wire harness 50 includes, for example, at least one electric wire 51. The electric wire 51 may be a covered electric wire having a conductor core wire and an insulating coating layer surrounding the conductor core wire. The electric wire 51 may be a shielded electric wire having a shield layer and a sheath around the insulating coating layer, or may be a non-shielded electric wire that does not have a shield layer around the insulating coating layer. The wire harness 50 may include at least one of a signal line and a power line. The wire harness 50 may include a twisted wire in which multiple covered electric wires are twisted together. The wire harness 50 may include other wiring members, such as an FPC (Flexible Printed Circuits) in which a circuit made of metal foil is formed on a resin film, in addition to or instead of a covered electric wire in which a conductor core wire is covered with an insulating coating layer.

[0039] The wire harness 50 connects a plurality of electrical components 21, 24. The number of electrical components 21, 24 connected to the wire harness 50 is not particularly limited and can be set as appropriate. Here, the wire harness 50 connects two electrical components 21, 24. The wire harness 50 may include a plurality of electric wires that branch off midway, and may connect three or more electrical components.

[0040] The positions of the electrical components 21, 24 connected to the wire harness 50 are not particularly limited and can be set as appropriate. In this example, the electrical component 21 is disposed inside the instrument panel 11. The electrical component 24 is disposed outside the instrument panel 11. The two electrical components may both be disposed inside the instrument panel 11, or may both be disposed outside the instrument panel 11.

[0041] The wire harness 50 is arranged in the vehicle 10 so as to connect the plurality of electrical components 21, 24 to each other. At least a portion of the path of the wire harness 50 is defined as a path along the intermediate base 40. Here, the path of the wire harness 50 that is along the intermediate base 40 is defined as a first path R1. Furthermore, the path of the wire harness 50 that is not along the intermediate base 40 and is arranged outside the vehicle is defined as a second path R2, and the path that is arranged inside the vehicle is defined as a third path R3. Here, the wire harness 50 has the first path R1, the second path R2, and the third path R3. Here, the path in the middle of the extension direction of the wire harness 50 is defined as the first path R1, the path at one end is defined as the second path R2, and the path at the other end is defined as the third path R3. The wire harness 50 does not have to have either or both of the second path R2 and the third path R3.

[0042] The first path R1 can be set as appropriate as long as it is a path that follows the intermediate base 40. Here, the first path R1 includes a path that extends in the left-right direction and paths that extend rearward while curving from both ends of the path that extends in the left-right direction.

[0043] The wire harness 50 in the first path R1 may be fixed to the intermediate base 40. The manner in which the wire harness 50 and the intermediate base 40 are fixed is not particularly limited and can be set as appropriate. The wire harness 50 may be fixed to the intermediate base 40 via a fixing member 54. The fixing member 54 may be an adhesive tape, a clip, an adhesive, or the like. For example, adhesive tape may be wrapped around the wire harness 50 and the periphery of the second hole 44B. For another example, a clip provided on the wire harness 50 may be inserted and locked into the first hole 44A. For another example, the wire harness 50 and the intermediate base 40 may be bonded together via an adhesive. The wire harness 50 may be fixed to the intermediate base 40 without the fixing member 54. For example, the intermediate base 40 may be provided with a protrusion that can hook and hold the wire harness 50. For another example, the wire harness 50 may be directly fused to the intermediate base 40.

[0044] The second path R2 and the third path R3 are set as appropriate depending on the positions of the electric components 21, 24 to be connected. In this example, the electric component 21 to which one end of the wire harness 50 is connected is located inside the instrument panel 11, and the second path R2 extends from one end of the first path R1 inside the instrument panel 11 in a direction away from the intermediate base 40. In this example, the electric component 24 to which the other end of the wire harness 50 is connected is located on the instrument panel 11, and the third path R3 extends from the other end of the first path R1 on the interior-side surface of the instrument panel 11.

[0045] Here, connectors C1 and C2 are provided at one end and the other end of the wire harness 50. Each connector C1 and C2 includes a plurality of terminals and a connector housing. The end of the conductor core wire of each electric wire 51 is connected to the terminal. The connector housing holds the plurality of terminals in a predetermined arrangement. The connector C1 at one end of the wire harness 50 is connected to a connector portion 22 of the electric component 21. The connector C2 at the other end of the wire harness 50 is connected to a connector portion 25 of the electric component 24.

[0046] Here, the wire harness 50 in the first path R1 is routed on the indoor side of the plate-shaped member 43. Meanwhile, the wire harness 50 in the second path R2 is located on the outdoor side of the plate-shaped member 43. Therefore, the wire harness 50 moves from the indoor side to the outdoor side of the plate-shaped member 43 at the connecting portion between the first path R1 and the second path R2. Here, the connecting portion of the wire harness 50 between the first path R1 and the second path R2 passes through the plate-shaped member 43.

[0047] The plate-like member 43 through which the wire harness 50 passes has holes 44 through which the connector C1 or the connector C2 can pass, and the wire harness 50 passes through the holes 44. Here, the size of the second holes 44B is formed to allow the connector C1 or the connector C2 to pass through. The wire harness 50 passes through some of the multiple second holes 44B, and moves from the indoor side to the outdoor side of the plate-like member 43. At this time, since the connector C1 or the connector C2 can pass through the second holes 44B, the wire harness 50 can pass through the hole 44 from the connector C1 or the connector C2.

[0048] In addition, the wire harness 50 in the first path R1 extends further outside the vehicle cabin than the instrument panel 11. The wire harness 50 in the third path R3 extends further inside the vehicle cabin than the instrument panel 11. Therefore, the wire harness 50 moves from the outside to the inside of the vehicle cabin than the instrument panel 11 at the connecting portion between the first path R1 and the third path R3. In this case, the connecting portion of the wire harness 50 between the first path R1 and the third path R3 passes through the upper panel 12A.

[0049] As shown in Figure 3, at the portion of the upper panel 12A through which the wire harness 50 passes, a slit S is formed in the outer edge (here, the side wall) through which the wire harness 50 can pass, and the wire harness 50 extends inside and outside the instrument panel 11 through the slit S.

[0050] The electrical component 24 disposed on the passenger compartment side of the instrument panel 11 may be disposed at a location other than on the instrument panel 11. For example, such an electrical component may be disposed on the roof. In this case, the wire harness 50 may have a third path that passes through a pillar and is guided to the roof. The electrical component may be disposed on the floor 19. In this case, the wire harness 50 may have a second path that is guided toward a lower opening of the instrument panel 11 and a third path that is drawn out to the passenger compartment side of the instrument panel 11 through the opening.

[0051] Here, a base wire harness 60 is arranged in the vehicle 10 so as to run along the reinforcement 20. The base wire harness 60 includes a plurality of electric wires connected to various electric components. The plurality of electric wires are bundled together so as to produce a trunk line 61 running along the reinforcement 20 and a plurality of branch lines 62 branching off from the trunk line 61. The trunk line 61 is supported by the reinforcement 20. Each branch line 62 is connected to various electric components via a connector provided at an end thereof.

[0052] The electrical components to which the base wire harness 60 is connected are, for example, electrical components that are arranged inside the instrument panel 11 or assembled to the instrument panel 11. For example, the base wire harness 60 is connected to an ECU (electronic control unit) that is arranged as an electrical component inside the instrument panel 11. Furthermore, for example, the base wire harness 60 may be connected to an instrument 15, an operation switch, an audio device, or the like that is assembled to the instrument panel 11 as an electrical component.

[0053] Here, the base wire harness 60 includes electric wires connected to the same electric component 21 as the electric component 21 to which the wire harness 50 is connected. The electric component 21 has a connector portion 23 separate from the connector portion 22 connected to the wire harness 50. A connector C3 at an end of a branch wire 62 in the base wire harness 60 is connected to the connector portion 23. The connector C3 of the base wire harness 60 and the connector C1 of the wire harness 50 may be directly connected (so-called wire-to-wire connection). In this case, the electric component to which the wire harness 50 is connected can be regarded as an electric component connected via the base wire harness 60, or as the connector C3 of the base wire harness 60.

[0054] For example, the base wire harness 60 may be assembled into the vehicle 10 during the manufacturing stage of the vehicle 10, and the wire harness 50 may be additionally assembled into the vehicle 10 after the manufacturing of the vehicle 10. The wire harness 50 may be assembled into the vehicle 10 together with the base wire harness 60 during the manufacturing stage of the vehicle 10. The number of circuits in the base wire harness 60 may be greater than the number of circuits in the wire harness 50. The base wire harness 60 may include circuits essential for the vehicle 10 to run, and the wire harness 50 may not include circuits essential for the vehicle 10 to run. One of the electrical components 21, 24 connected to the wire harness 50 (for example, the electrical component 24 to which the base wire harness 60 is not connected) may be, for example, a terminal device used by a passenger, and the vehicle 10 may be able to run normally without that terminal device. The terminal device may be, for example, a device that enhances passenger comfort, convenience, entertainment, or the like.

[0055] <Effects, etc.> According to the wire harness routing structure 30 configured as described above, routing the wire harness 50 from the passenger compartment side is easier when the wire harness 50 is routed along the intermediate base 40 located between the instrument panel 11 and the reinforcement 20 than when the wire harness 50 is routed along the reinforcement 20. In addition, the portion of the wire harness 50 routed along the intermediate base 40 can be hidden from the passenger compartment by the instrument panel 11. As a result, the wire harness 50 can be easily added to the vehicle 10, and exposure of the added wire harness 50 to the passenger compartment can be minimized.

[0056] Furthermore, the intermediate base 40 is provided at a position closer to the instrument panel 11 than the reinforcement 20. This makes it easier to access the intermediate base 40 from the inside of the vehicle. An operator can easily remove the instrument panel 11 and route the wire harness 50 to the intermediate base 40 from the inside of the vehicle.

[0057] The intermediate base 40 is formed in a plate shape and is provided on the rear side of a part of the instrument panel 11 so as to face the instrument panel 11. As a result, when the wire harness 50 is routed along the intermediate base 40, the wire harness 50 is also routed along the instrument panel 11.

[0058] In addition, a portion of the instrument panel 11 that covers the intermediate base 40 is provided detachably relative to the other portion, so that the wire harness 50 can be easily routed to the intermediate base 40 after removing the instrument panel 11.

[0059] The intermediate base 40 has a first extending portion 41 extending in the left-right direction of the vehicle 10 and a second extending portion 42 extending in the front-rear direction of the vehicle 10 from a part of the first extending portion 41. This makes it easy to route the wire harness 50 in the left-right and front-rear directions of the vehicle 10.

[0060] The first extending portion 41 extends from the area in front of the driver's seat 17 to the area in front of the passenger seat 18. This makes it easy to route the wire harness 50 across the entire left-right direction of the vehicle 10.

[0061] Furthermore, the second extending portion 42 is partially provided in the area in front of the passenger seat 18. This makes it easier to connect the end of the wire harness 50 on the passenger seat 18 side. Specifically, the passenger seat 18 does not have the steering wheel 16, the instruments 15, etc., and has relatively more space than the area in front of the driver's seat 17. Therefore, it is easier to connect the end of the additional wire harness 50 on the passenger seat 18 side than on the driver's seat 17 side.

[0062] Furthermore, a plurality of holes 44 are formed in the intermediate base 40, and the wire harness 50 is fixed by selectively using some of the plurality of holes 44. This makes it easy to fix the wire harness 50 to the intermediate base 40 at any position.

[0063] The intermediate base 40 is fixed to the instrument panel 11. This allows the intermediate base 40 to be attached to the instrument panel 11.

[0064] [Note] FIG. 5 is a cross-sectional view showing a modified example of the intermediate base 40. As shown in FIG.

[0065] A groove 45 is formed in the intermediate base 140 according to the modified example. The wire harness 50 is accommodated in the groove 45. By routing the wire harness 50 along the groove 45 of the intermediate base 140 in this manner, the wire harness 50 can be easily routed in the intermediate base 140.

[0066] Here, the groove 45 is formed on the surface of the intermediate base 140 facing the upper panel 12. The upper side of the wire harness 50 accommodated in the groove 45 is blocked by the upper panel 12. This prevents the wire harness 50 from slipping out of the groove 45.

[0067] In addition, although the intermediate base 40 has been described as being located closer to the instrument panel 11 than the reinforcement 20, this is not a necessary configuration. The intermediate base 40 may be located closer to the reinforcement 20 than the instrument panel 11.

[0068] Although the intermediate base 40 has been described so far as being formed in a plate shape and provided on the rear side of a portion of the instrument panel 11 facing the instrument panel 11, this is not a required configuration. For example, the intermediate base 40 may be formed in a rod or cylinder shape.

[0069] Although the portion of the instrument panel 11 that covers the intermediate base 40 has been described as being detachable from the other portion, this is not a required configuration. For example, the portion of the upper panel 12 that covers the intermediate base 40 and the other portion may be integrally formed.
