[0031] [Description of embodiments of this disclosure]

[0032] First, let's illustrate the implementation forms of this disclosure.

[0033] The wiring module disclosed herein is as follows.

[0034] (1) A wiring module comprising: a functional sheet disposed between a roof panel forming a vehicle's passenger compartment roof portion and an interior component forming a ceiling shape within the vehicle interior, and extending planarly relative to the roof panel and the interior component; a conveying member disposed on the functional sheet; a roof-side device disposed on the functional sheet; and a rigid member disposed on the functional sheet, the functional sheet comprising a layer having at least one of a heat insulation function, a sound insulation function, and an electromagnetic shielding function, the conveying member being disposed on the functional sheet along a wiring path connecting at least one end to the roof-side device. According to this disclosure, the portion of the functional sheet with the rigid member is less likely to droop. Therefore, the wiring module can be easily installed into the passenger compartment roof portion of a vehicle.

[0035] (2) In the wiring module of (1), the roof-side device may also include a supporting roof-side device, and the rigid member is disposed on the area on the functional sheet where the supporting roof-side device is disposed. Thus, the supporting roof-side device is firmly supported by the rigid member.

[0036] (3) In the wiring module of (1) or (2), the rigid member may also include a roof fixing part, which is fixed to the roof of the vehicle. Thus, the rigid member is securely fixed to the roof of the vehicle via the roof fixing part.

[0037] (4) In the wiring module of (3), the roof mounting portion may also include a retaining hole that supports the embedded mounting portion fixed to the roof portion of the vehicle in a state that allows movement in the direction of expansion of the functional sheet. Thus, the embedded mounting portion is supported by the retaining hole in a state that allows easy movement in the direction of expansion of the functional sheet. Therefore, the embedded mounting portion can be easily embedded and fixed to the roof portion.

[0038] The wiring module group disclosed herein is as follows.

[0039] (5) A wiring module assembly comprising: an interior component-side wiring module, including an interior component-side conveying member disposed on an interior component forming a ceiling shape within a vehicle interior; and a wiring module as described in any one of (1) to (4). Thus, the interior component-side conveying member in the interior component-side wiring module and the conveying member in the wiring module can be respectively installed in the roof portion of a vehicle. Therefore, it is possible to easily accommodate differences in grade, the presence or absence of optional components, etc.

[0040] (6) A wiring module assembly comprising: a wiring module having a functional sheet, a conveying member, and a roof-side device, the functional sheet being disposed between a roof panel forming the roof portion of a vehicle body and an interior component forming the shape of a ceiling within the vehicle interior and extending planarly relative to the roof panel and the interior component; the conveying member being disposed on the functional sheet; the roof-side device being disposed on the functional sheet; the functional sheet comprising a layer having at least one of the functions of heat insulation, sound insulation, and electromagnetic shielding; the conveying member being disposed on the functional sheet along a wiring path connecting at least one end to the roof-side device; and an interior component-side wiring module having an interior component-side conveying member disposed on the interior component.

[0042] (8) In the wiring module group of (6) or (7), the interior component side conveying component may also be a component connected to roof-side equipment fixed to any one of the roof panel, the frame supporting the roof panel and the interior component.

[0043] [Details of the embodiments of this disclosure]

[0044] The following describes specific examples of the wiring module and wiring module group of this disclosure with reference to the accompanying drawings. It should be noted that this disclosure is not limited to these examples, but is disclosed by the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0045] [Implementation Method 1]

[0046] The wiring module of Implementation Method 1 will be described below.

[0047] <Regarding vehicles equipped with wiring modules>

[0048] Figure 1 This is a schematic perspective view of a vehicle 10 equipped with a wiring module 20. The vehicle 10 includes a body 12. The body 12 forms the outer shape of the vehicle 10. The body 12 can be a monocoque body or a body mounted on a ladder frame. Here, the body 12 includes side panels surrounding the passenger compartment, a roof panel 13, and access panels for passengers to get in and out, and a rear door panel for loading and unloading cargo. The body 12 can be made of metal or resin. The body 12 can also be constructed using a combination of metal and resin. The plate-like portion of the body 12 that covers the top of the passenger compartment is the roof panel 13. That is, the roof panel 13 forms the roof of the vehicle 10. The roof panel 13 can be partially or entirely bent to form the external shape of the body 12. The roof panel 13 can be made of metal or resin. The roof panel 13 can also be constructed using a combination of metal and resin. Here, an antenna hole 13h is formed in the roof panel 13 (see reference). Figure 2 ).

[0049] Wiring module 20 is installed in vehicle 10. In this embodiment, an example of wiring module 20 being installed in the roof portion 14 of the vehicle body, which includes roof panel 13, will be described.

[0050] Figure 2 This is a 3D view showing the wiring module 20. Figure 2 The image shows the roof section 14 of the carriage. Figure 3 This is an exploded perspective view of the wiring module 20. Figure 2 and Figure 3The conveying components shown represent a general path; even when depicted as a single line, they sometimes include multiple wires, etc. The roof panel 13 and interior component 16 are shown as the vehicle roof portion 14. The vehicle roof portion 14 sometimes includes a frame that supports the roof panel 13. The interior component 16 is a sheet-like component formed of resin or the like. The interior component 16 forms the shape of the ceiling inside the vehicle interior. The interior component 16 may also be partially or entirely bent. The interior component 16 is mounted below the roof panel 13. The interior component 16 is the portion exposed into the vehicle interior. The interior component 16 is sometimes also referred to as a roof liner. In this embodiment, the wiring module 20 is disposed between the roof panel 13 and the interior component 16.

[0051] <About the overall structure of the wiring module>

[0052] The wiring module 20 includes a functional sheet 30, a conveying component 40, a roof-side device 50, and a rigid component 60.

[0053] The functional sheet 30 comprises a layer having at least one of the following functions: heat insulation, sound insulation, and electromagnetic shielding. That is, the functional sheet 30 is a sheet that, in addition to securing the transmission member 40, the roof-side equipment 50, and the rigid member 60, also has at least one of the following functions: heat insulation, sound insulation, and electromagnetic shielding. Specific examples of functional sheets 30 having these functions will be described later.

[0054] The functional sheet 30 is installed in the roof portion 14 of the vehicle body in a planar manner, extending relative to the roof panel 13 and the interior components 16. For example, the functional sheet 30 may be arranged to extend more than 80% of the area relative to the roof portion 14. Moreover, for example, the functional sheet 30 may be arranged integrally above the headrests of multiple passenger seats in the vehicle interior. By extending the functional sheet 30 relative to the roof portion 14, the conveyor components 40 and the roof-side equipment 50 can be supported over the widest possible area relative to the roof portion 14. Furthermore, the functions of the functional sheet 30 can be performed over the widest possible area relative to the roof portion 14.

[0055] The transmission component 40 is a component that transmits electricity or light, and is a component provided in the functional sheet 30 along a wiring path connected at least one end to the roof-side equipment 50. For example, the transmission component 40 can be a general wire with a core wire and a surrounding sheath, or it can be a bare wire, shielded wire, electrical cable, enameled wire, nickel-chromium alloy wire, coaxial cable, optical fiber, etc. That is, the transmission component 40 can also be a linear component that transmits electricity. As a linear component that transmits electricity, it can also be various signal lines or various power lines. Moreover, the linear transmission component that transmits electricity can be a single linear object or a composite of multiple linear objects (stranded wire, cable that aggregates multiple linear objects and covers them with a sheath, etc.). The transmission component can also be formed by coating the functional sheet with a conductive coating, etching copper foil, etc. Here, we will explain the case where the transmission component 40 is an electrical wire.

[0056] A transmission member 40 is disposed on the functional sheet 30. Here, "distributing the transmission member 40 on the functional sheet 30" refers to the case where a medium for transmitting electricity or light is formed on the functional sheet as a path for electricity or light. Therefore, the transmission member 40 disposed on the functional sheet 30 includes not only transmission members directly formed on the functional sheet 30 by applying conductive coating, etching copper foil, etc., but also transmission members that are separately manufactured as linear transmission members 40 and mounted along a certain path formed on any one or two main surfaces of the functional sheet 30. The specific structure for supporting the transmission member 40 is not particularly limited.

[0057] For example, the conveying member 40 may also be fixed to a main surface of the functional sheet 30. Alternatively, the conveying member 40 may be fused (also called welded) to a main surface of the functional sheet 30. The resulting fused portion becomes a state where at least a portion of the conveying member 40 and the functional sheet 30 is melted and adhered to each other. The fusion of the conveying member 40 and the functional sheet 30 can be performed by ultrasonic fusion or by heating fusion. Furthermore, the conveying member 40 and the functional sheet 30 may be fused together by melting the surfaces of at least one of them with a solvent. Moreover, the conveying member 40 may also be fixed to the functional sheet 30 by adhesive, double-sided tape, etc. Furthermore, the conveying member 40 may also be sewn onto the functional sheet 30 by thread, etc. Furthermore, for example, with the conveying member 40 disposed on one main surface of the functional sheet 30, adhesive tape can be applied across the conveying member 40 from the outside of one main surface of the functional sheet 30, thereby fixing the conveying member 40 to one main surface of the functional sheet 30. The conveying member 40 does not need to be fixed to only one main surface of the functional sheet 30. The conveying member 40 may simultaneously have a portion fixed to one main surface of the functional sheet 30 and a portion fixed to another main surface of the functional sheet 30. In this case, the conveying member 40 may also be attached to the middle portion or end edge of the functional sheet 30 in a manner that passes from one main surface to another.

[0058] Alternatively, for example, the conveying member 40 can also be fixed to the functional sheet 30 by being sandwiched between two sheets. For example, if the functional sheet 30 comprises multiple layers, the conveying member 40 can also be sandwiched between the sheets constituting each layer. Moreover, if the functional sheet 30 overlaps with other sheets, the conveying member 40 can be sandwiched between the functional sheet 30 and the other sheets. In this case, the two sheets into which the conveying member 40 is sandwiched can be fixed to each other by welding, or by adhesive or double-sided tape.

[0059] Here, the conveying member 40 is mainly disposed on the side of the inner member 16 relative to the functional sheet 30.

[0060] The transmission component 40 is connected to the roof-side device 50. The roof-side device 50 transmits or receives electrical or optical signals via the transmission component 40. Alternatively, the roof-side device 50 receives or distributes power via the transmission component 40. The connection between the transmission component 40 and the roof-side device 50 can also be made via a connector. Alternatively, the transmission component 40 can be directly inserted into the roof-side device 50 and directly connected to the electrical components within the roof-side device 50.

[0061] The roof-side equipment 50 is a device disposed on the roof portion 14 of the vehicle body and serves as the connection destination of the transport component 40. Examples of roof-side equipment 50 include, for instance, electronic control units, lights (especially map lights and interior lights), speakers, interior cameras, monitors, projection equipment, external communication antennas, and interior antennas.

[0062] The roof-side device 50 is a device disposed on the functional sheet 30. The configuration position of the roof-side device 50 relative to the functional sheet 30 is arbitrary. Preferably, the roof-side device 50 is fixed relative to the functional sheet 30 in a position suitable for the roof-side device 50 to function. For example, when the roof-side device 50 is conceived as a map light, it can also be fixed to a portion of the functional sheet 30 positioned diagonally above and in front of the front seat. Furthermore, for example, when the roof-side device 50 is conceived as an indoor antenna, it can also be fixed to a portion of the functional sheet 30 positioned above the front or rear seats.

[0063] The roof-side device 50 can also be ultimately fixed to the roof panel 13 or the interior component 16, etc. Therefore, the roof-side device 50 can be held in place by a holding force within the functional sheet 30. For example, the roof-side device 50 can also be fixed to the functional sheet 30 using adhesives, bonding agents, double-sided tape, etc. The roof-side device 50 can also be fixed to the functional sheet 30 using screws, pins, etc. The roof-side device 50 can also be fixed to the functional sheet 30 via a rigid member 60. In this case, the roof-side device 50 can be fixed to the rigid member 60 using adhesives, bonding agents, double-sided tape, etc., or it can be fixed to the rigid member 60 using screws, pins, etc.

[0064] Figure 4 This is a functional block diagram of wiring module 20. Figure 4 In this context, regardless of the number of functional parts, each represents a representative functional part. (See reference...) Figures 2-4 This illustrates an example of the roof-side device 50.

[0065] The multiple roof-side devices 50 include an electronic control unit 51, an indoor antenna 52, an external communication antenna unit 53, a light 54, a camera 55, and a speaker 56. Hereinafter, when referring to the roof-side devices as a whole, refer to the reference numeral 50; when distinguishing them individually, refer to the reference numerals 51, 52, 53, 54, 55, and 56.

[0066] The electronic control unit 51 is a computer including a processor, memory, etc., that executes control processing according to a pre-stored program. The electronic control unit 51 can be, for example, a regional ECU (Electronic Control Unit) controlling various devices located on the roof of the vehicle. The electronic control unit 51 is connected to the vehicle-side device 18 via a relay transmission member 19. The vehicle-side device 18 can be another electronic control unit (e.g., a body ECU, a central ECU, etc.) 18 located below the roof. The vehicle-side device 18 can also replace the electronic control unit or serve as a power supply unit. The relay transmission member 19 includes at least one of a communication line and a power line. The relay transmission member 19 is, for example, arranged along a pillar, with wiring from the roof toward the vehicle-side device. The electronic control unit 51 is electrically connected to the vehicle-side device 18 via the relay transmission member 19.

[0067] The electronic control unit 51 can be communicatively connected to other devices installed on the roof, such as an indoor antenna 52, an external communication antenna unit 53, a light 54, a camera 55, and a speaker 56, via a transmission member 40. The transmission member 40 may also include communication lines. The electronic control unit 51 can control other roof-side devices 52, 53, 54, 55, and 56 installed on the roof via the transmission member 40.

[0068] The transmission component 40 may also include a power line. The power line included in the transmission component 40 can be directly connected to the power line included in the relay transmission component 19, or it can be directly connected to the power line included in the relay transmission component 19 via a power branch box or the like. The power branch box is a device that houses branch circuits composed of busbars or the like, circuit-cutting components composed of fuses or semiconductor elements, etc. The power branch box can be installed in the electronic control unit 51, or it can be configured as a separate device from the electronic control unit 51.

[0069] The positions of the roof-side devices 51, 52, 53, 54, 55, and 56 in the functional sheet 30, and the path of the conveying component 40, are arbitrary. Figure 2 and Figure 3 In the example shown, an electronic control unit 51 and a portion of a lamp 54 are positioned at the center of the width direction in the area near the front of the functional sheet 30. An external communication antenna unit 53 is positioned at the center of the width direction in the area near the rear of the functional sheet 30. It should be noted that the direction of vehicle travel is forward, and the opposite is rearward. Moreover, left and right are determined based on the forward position. The electronic control unit 51 may also be positioned offset to the right or left of the functional sheet 30.

[0070] Here, the external communication antenna unit 53 includes external communication antennas 53a and 53b for wireless communication with devices outside the vehicle. The external communication antenna unit 53 is formed in a flat shape. External communication antennas 53a and 53b are housed within the external communication antenna unit 53. The external communication antennas 53a and 53b are, for example, antennas for communication with wireless base stations on public or dedicated communication lines, antennas for vehicle-to-vehicle or road-to-road communication, and antennas for receiving GPS signals. Here, the external communication antenna unit 53 is a composite antenna unit containing multiple external communication antennas 53a and 53b and enabling external communication in multiple ways. The external communication antenna unit 53 may have only one antenna or more than three antennas.

[0071] Here, the external communication antenna unit 53 is formed in a thin box shape. The external communication antenna unit can also be formed in a fin shape or a rod shape. In this case, the fin-shaped or rod-shaped external communication antenna unit is inserted into a hole formed in the roof panel, or it can protrude outwards from the roof panel. This easily allows the external communication antenna to be exposed to the outside, enabling good external communication through the external communication antennas 53a and 53b. The external communication antenna is preferably mounted on the fin-shaped or rod-shaped external communication antenna unit in a manner located on the outside of the roof panel. The external communication antenna unit can also be mounted on the vehicle body 12 instead of the functional sheet 30. In this case, the connector provided at the end of the transmission member 40 of the functional sheet 30 can also be connected to the external communication antenna unit on the side of the vehicle body 12.

[0072] Multiple cameras 55 are separately arranged in the left and right regions of the functional sheet 30. Within each left and right region, the multiple cameras 55 are arranged front-to-back. Similarly, multiple speakers 56 are separately arranged in the left and right regions of the functional sheet 30. Within each left and right region, the multiple speakers 56 are arranged front-to-back. Furthermore, multiple lights 54 are separately arranged in the left and right regions of the functional sheet 30. Within each left and right region, the multiple lights 54 are arranged front-to-back.

[0073] In the left and right areas of the functional sheet 30, a camera 55 and a light 54 are arranged around the frontmost speaker 56, a light 54 is arranged around the middle speaker 56 in the front-to-back direction, and a camera 55 and a light 54 are arranged around the rearmost speaker 56.

[0074] Furthermore, multiple indoor antennas 52 are arranged approximately separately from the functional sheet 30. Here, the multiple indoor antennas 52 are positioned rearward of the electronic control unit 51 and forward of the external communication antenna unit 53. The multiple indoor antennas 52 are arranged approximately separately to the left and right, and also to the front and rear. More specifically, the multiple indoor antennas 52 are positioned in areas corresponding to the seats, and more specifically, above the left and right seating areas of the driver's seat, passenger seat, and rear seats. The indoor antennas 52 are used, for example, in contactless power supply (Wi-Fi power supply).

[0075] Each of the roof-side devices 51, 52, 53, 54, 55, and 56 can be disposed on any side of the functional sheet 30. In this embodiment, an example is shown where the external communication antenna unit 53 is disposed on the side of the roof panel 13 in the functional sheet 30. Furthermore, an example is shown where the electronic control unit 51, the interior antenna 52, the lamp 54, the camera 55, and the speaker 56 are disposed on the side of the interior component 16 in the functional sheet 30.

[0076] The conveying member 40 is connected to each of the roof-side devices 52, 53, 54, 55, and 56 via paths branching to the left and right from the electronic control unit 51. For example, when viewing the left-hand area relative to the functional sheet 30, a portion of the conveying member 40 extends to the left from the electronic control unit 51. This portion of the conveying member 40 bends in front of the left edge of the functional sheet 30 and extends forward or backward along that left edge, connecting to each of the roof-side devices 52, 53, 54, 55, and 56 located on the left side of the functional sheet 30. Moreover, for example, when viewing the right-hand area relative to the functional sheet 30, another portion of the conveying member 40 extends to the right from the electronic control unit 51. The other part of the conveying component 40 bends in front of the right edge of the functional sheet 30 and extends forward or backward along the right edge, connecting to the roof-side devices 52, 53, 54, 55, and 56 located on the right side of the functional sheet 30.

[0077] The aforementioned relay transmission member 19 extends forward from the electronic control unit 51. Here, the relay transmission member 19 separates from the electronic control unit 51 to the left and right, extending forward along the left and right edges of the functional sheet 30. The relay transmission member 19 is guided to the vehicle body side, for example, along the A-pillar. The relay transmission member 19 can be directly led out from the electronic control unit 51, or it can be connected to the electronic control unit 51 via a connector. The relay transmission member 19 can also be guided towards the A-pillar, etc., without being installed on the functional sheet 30, in a state separated from the functional sheet 30.

[0078] It should be noted that when the roof-side equipment is located on a different surface relative to the functional sheet 30, the transmission member 40 can pass through the functional sheet 30. For example, the transmission member 40 connected to the external communication antenna unit 53 is wired from the electronic control unit 51 through the surface of the functional sheet 30 on the side of the internal component 16 to the vicinity of the external communication antenna unit 53, and can also extend through the functional sheet 30 to the roof panel 13 side near the external communication antenna unit 53.

[0079] The rigid member 60 is a component disposed on the functional sheet 30. The rigid member 60 imparts resistance to deformation to the functional sheet 30. Preferably, the rigid member 60 has higher rigidity than the functional sheet 30. The level of rigidity can be evaluated, for example, by using a plane of the rigid member 60 orthogonal to its length direction as a reference plane, or by the bending rigidity at this reference plane, or by the bending rigidity at this reference plane in the region of the functional sheet 30 where the rigid member 60 is disposed. For example, the functional sheet 30 may be a laminate of aluminum foil and nonwoven fabric, and the rigid member 60 may be a sheet or rod made of resin (e.g., PP (polypropylene), PA (polyamide), etc.) internally filled. The rigid member 60 may also be a component that possesses strength and achieves lightweighting, such as a honeycomb structure component. The rigid member 60 may also be formed of metals such as iron or aluminum.

[0080] The rigid member 60 is fixed to the functional sheet 30 by adhesives, bonding agents, double-sided tape, or welding (ultrasonic welding, thermal welding, etc.). The rigid member 60 can also be fixed to the functional sheet 30 by screws, pins, etc. Here, the rigid member 60 is formed into an elongated rectangular plate. The length of the rigid member 60 is set to be the same as the width of the functional sheet 30. The length of the rigid member 60 can also be designed to prevent the edge of the functional sheet 30 from drooping downwards to a degree smaller than the width of the functional sheet 30 (for example, a range of less than 20 cm). The rigid member 60 is disposed on the side of the roof panel 13 of the functional sheet 30. The opposing surfaces of the two are joined by adhesives or the like.

[0081] In this embodiment, a plurality of (four in this case) rigid members 60 are fixed to the functional sheet 30. The length direction of each rigid member 60 is along the width direction of the functional sheet 30. Therefore, the portion of the functional sheet 30 with the rigid members 60 is kept from sagging in the width direction.

[0082] Multiple rigid members 60 are spaced apart from the functional sheet 30 in the front-to-back direction. Therefore, the functional sheet 30 can be bent between the multiple rigid members 60. When storing or transporting this wiring module 20, the storage space and transport space of the wiring module 20 can be reduced by folding the functional sheet 30 between the multiple rigid members 60.

[0083] The rigid member 60 can be positioned arbitrarily relative to the functional sheet 30. Alternatively, the rigid member 60 can be positioned in a localized area relative to the functional sheet 30.

[0084] Alternatively, the speaker 56 in the aforementioned roof-side device 50 can serve as the supporting object for the roof-side device, with the rigid member 60 disposed in the area of ​​the functional sheet 30 where the speaker 56 is located. Figure 2 and Figure 3 In the functional sheet 30, multiple speakers 56 are separately arranged in three regions, front and rear, in the front-rear direction. Rigid members 60 are provided in the three regions where the speakers 56 are located. In each of the above regions, the rigid member 60 is fixed on the surface of the functional sheet 30 on the side of the roof panel 13, and the speaker 56 is fixed on the surface of the interior component 16.

[0085] Alternatively, the external communication antenna unit 53 in the roof-side device 50 can be used as the supporting object for the roof-side device, and the rigid member 60 can be disposed in the area of ​​the functional sheet 30 where the external communication antenna unit 53 is located. Figure 2 and Figure 3 An external communication antenna unit 53 is disposed in the rearward region of the functional sheet 30. A rigid member 60 is disposed in the region where the external communication antenna unit 53 is disposed. In this region, the rigid member 60 is fixed to the surface of the functional sheet 30 on the side of the roof panel 13, and the external communication antenna unit 53 is fixed to the upper side thereon. The external communication antenna unit 53 may also be fixed to the functional sheet 30 on the outer side of the rigid member 60. The external communication antenna unit 53 may also be fixed to the rigid member 60.

[0086] The supported roof-side equipment can be all or a portion of the multiple roof-side equipment 50. The supported roof-side equipment can also be a heavy component among the multiple roof-side equipment 50. For example, a speaker 56 and an external communication antenna unit 53 are examples of heavy components. A rigid member 60 is provided in the area of ​​the functional sheet 30 where the speaker 56 and the external communication antenna unit 53 are located, thereby easily and securely supporting the speaker 56 and the external communication antenna unit 53. The supported roof-side equipment can also be equipment exposed into the vehicle interior, such as a light 54, a camera 55, a switch, etc. These devices may be pressed down from the vehicle interior. Therefore, if a rigid member 60 is provided on the outside of these devices, the rigid member 60 can withstand the pressing force.

[0087] It should be noted that, with the wiring module 20 installed in the roof section 14, each roof-side device 50 can be fixed to any location. The roof-side device 50 can also be fixed to the roof panel 13 or the frame supporting the roof panel 13. The roof-side device 50 can also be fixed to the interior component 16. If the rigid component 60 is fixed to the roof panel 13 or the frame supporting the roof panel 13, the roof-side device 50 can also be fixed only to the rigid component 60.

[0088] The rigid member 60 preferably includes a roof fixing part 70 for fixing to the roof portion 14 of the vehicle. Here, the roof fixing part 70 is formed in the rigid member 60, protruding upwards. The roof fixing part 70 is a part that is fixed to the roof panel 13 in the roof portion 14 or a frame supporting the roof panel 13. The roof fixing part 70 can be conceived as, for example, a clip-shaped part, a screw, etc., that is fixed in place by insertion. The rigid member 60 is not necessarily fixed to the roof portion 14.

[0089] Figure 5 This is a schematic cross-sectional view showing the wiring module 20. Figure 5 The diagram shows a roof panel 13, a frame 13F supporting the roof panel 13, and interior components 16. The frame 13F is, for example, a long, rigid member disposed on the inner side of the roof panel 13, and is referred to as a reinforcing bar or strut. The frame 13F is disposed, for example, along the width of the vehicle.

[0090] As shown in the figure, the rigid member 60 is fixed to the frame 13F via the roof fixing part 70. The functional sheet 30 is located on the side of the interior member 16 relative to the rigid member 60.

[0091] The functional sheet 30 holds the electronic control unit 51, interior antenna 52, lamp 54, camera 55, speaker 56, etc., on the side of the interior component 16. These components can be mounted solely on the interior component 16 or fixed to it via an embedded structure. The lamp 54 and camera 55 can also be exposed into the vehicle interior. In this case, a recess 16h can be formed in the interior component 16 for the lamp 54 and camera 55 to be embedded, and an opening 16ha can be formed in the recess 16h to expose the lamp 54 and camera 55 into the vehicle interior.

[0092] It should be noted that, in Figure 5 In this configuration, a functional sheet 30 is provided above the lamp 54 and camera 55, and a rigid member 60 is provided above that. Therefore, even if the lamp 54 and camera 55 are pressed, the force is absorbed by the rigid member 60, which can prevent the lamp 54 and camera 55 from retracting from the interior member 16 toward the roof panel 13.

[0093] An external communication antenna unit 53 is provided on the side of the roof panel 13 relative to the functional sheet 30. The rigid member 60 between the external communication antenna unit 53 and the functional sheet 30 can be fixed to the frame 13F via the roof fixing part 70 on the outside of the external communication antenna unit 53. The external communication antenna unit 53 is exposed to the outside through an antenna hole 13h formed in the roof panel 13.

[0094] The functional sheet 30 is disposed between the interior component 16 and the roof panel 13. The functional sheet 30 can be fixed to the interior component 16 or simply placed on the interior component 16. For example, the functional sheet 30 can also be fixed to the interior component 16 by means of double-sided tape, adhesive, fusion, etc.

[0095] As described above, the functional sheet 30 includes a layer having at least one of the following functions: heat insulation, sound insulation, and electromagnetic shielding. Figure 5 In this embodiment, the functional sheet 30 includes a nonwoven fabric layer 32 and an electromagnetic shielding layer 34. The functional sheet 30 has a multi-layered structure in which the nonwoven fabric layer 32 and the electromagnetic shielding layer 34 are overlapped from bottom to top. The overlapping order of the layers is arbitrary. For example, the electromagnetic shielding layer 34 may be provided below the nonwoven fabric layer 32. When the functional sheet has multiple functional layers, the multiple functional layers do not necessarily have to be overlapped in the thickness direction of the functional sheet. Multiple functional layers may also be provided in different areas within the extended region of the functional sheet. For example, multiple functional layers may be arranged laterally within the extended region of the functional sheet. Other functional layers may also be provided locally relative to one functional layer.

[0096] The nonwoven layer 32 is an example of a layer that provides insulation between one main surface and the other main surface of the functional sheet 30, making heat transfer difficult. The insulation layer can also be a layer that reflects radiant heat energy. The insulation layer can also be a layer with low thermal conductivity compared to other layers. For example, in addition to nonwoven sheets, sheets containing fine gaps, such as foam sheets, can also be used as the insulation layer. Insulating coatings and heat-insulating coatings can also be used as the insulation layer.

[0097] The nonwoven layer 32 can also be used as an example of a sound-insulating layer that makes sound transmission difficult, located between one main surface and the other main surface of the functional sheet 30. The sound-insulating layer can be a structure that reflects sound or a structure that absorbs sound energy as heat. For example, in addition to nonwoven sheets, sheets containing fine gaps, such as foam sheets, can also be used as sound-insulating layers. Sound-absorbing coatings can also be used as sound-insulating layers.

[0098] The thermal insulation layer and the sound insulation layer can also be physically set as different layers.

[0099] The radio wave shielding layer 34 is a layer that makes it difficult for radio waves to propagate between one main surface and the other main surface of the functional sheet 30. The radio wave shielding layer 34 can also be radio wave shielding for all frequencies. The radio wave shielding layer 34 can also be selectively radio wave shielding for a specific frequency band. In this case, radio waves in a specific frequency band only need to be reflected or absorbed within the radio wave shielding layer at least once. The radio wave shielding layer 34 can also be a layer formed of metal foil such as aluminum or iron. As a selectively shielding radio wave shielding layer 34, a well-known frequency selective surface (FSS) can also be used. Figure 5 This diagram illustrates an example of a frequency-selective film. A frequency-selective film has a structure in which unit elements (components) are formed on a base film made of resin or the like using metal foil. The aforementioned frequency-selective film has the property of selectively shielding radio waves of one or more frequency bands while allowing radio waves of other frequency bands to pass through, based on the frequency characteristics of the unit elements (components). Radio wave shielding layers with selective radio wave shielding properties can also be formed by directly printing conductive paste or the like onto a heat-insulating layer or a sound-insulating layer.

[0100] It should be noted that the layers can also simply overlap. The layers can also be fixed together using double-sided tape, adhesives, or welding.

[0101] When the wiring module 20 includes a radio wave shielding layer 34, the external communication antenna unit 53 is preferably disposed on the outside of the vehicle relative to the radio wave shielding layer 34. Therefore, radio waves emitted from the external communication antennas 53a and 53b are shielded by the radio wave shielding layer 34, making it difficult for them to propagate into the vehicle interior. Furthermore, radio waves emitted from the external communication antennas 53a and 53b propagate to the outside without being shielded by the radio wave shielding layer 34. Therefore, wireless communication with external devices (base stations, etc.) via the external communication antennas 53a and 53b can be performed effectively. Moreover, since radio waves are not transmitted into the vehicle interior, the radiation efficiency of radio waves to the outside of the vehicle is increased. From this point of view, wireless communication with external devices (base stations, etc.) via the external communication antennas 53a and 53b can also be performed effectively.

[0102] Furthermore, assuming the wiring module 20 includes a radio wave shielding layer 34, the indoor antenna 52 is preferably positioned on the vehicle interior side relative to the radio wave shielding layer 34. As a result, radio waves emitted from the indoor antenna 52 and indoor equipment within the vehicle interior are shielded by the radio wave shielding layer 34, making it difficult for them to propagate outside the vehicle. Consequently, radio waves used for wireless communication by the indoor antenna 52 are shielded by the radio wave shielding layer 34, making it difficult for them to propagate outside the vehicle. On the other hand, radio waves emitted by the indoor antenna 52 propagate towards the vehicle interior side opposite to the radio wave shielding layer 34. Therefore, good wireless communication can be achieved between the indoor antenna 52 and indoor equipment. Moreover, when the indoor antenna 52 provides contactless power supply to indoor equipment, radio waves (power) do not leak outside the vehicle, thus enabling effective contactless power supply.

[0103] It should be noted that, regarding the indoor antenna 52, since it is relatively thin and lightweight, it can be fixed only to the functional sheet 30 and not to the internal component 16.

[0104] This describes a specific example of the fixed part 70 on the top of the carriage. Figure 6 and Figure 7 This is a perspective view showing the carriage roof fixing part 70 installed on the rigid member 60. Figure 8 This is a sectional view showing the fixed part 70 on the top of the carriage.

[0105] The carriage roof fixing part 70 is configured such that the fixing part 72 is embedded in the retaining hole 64 formed in the rigid member 60.

[0106] The retaining hole 64 is formed in the plate-like portion 61 of the rigid member 60. That is, the rigid member 60 is provided with a plate-like portion 61 that extends along its main surface direction. The plate-like portion 61 may be an integral part of the portion of the rigid member 60 that is fixed to the functional sheet 30, or it may be a part that is installed separately from the portion that is fixed to the functional sheet 30 by means of welding, bonding, screw fastening, embedding, etc.

[0107] A retaining hole 64 is formed at a position separating inward from the edge of the plate-shaped portion 61. The retaining hole 64 is formed in the shape of a circular hole. A slit-shaped guide portion 65 is formed from the retaining hole 64 toward the edge of the plate-shaped portion 61. The guide portion 65 includes a pair of guide edges 65a that gradually narrow from the edge of the plate-shaped portion 61 toward the retaining hole 64. A retraction opening 65h is formed at the portion separating from the pair of guide edges 65a. Therefore, the pair of guide edges 65a can be elastically deformed in a way that the retraction opening 65h narrows and widens the space between the pair of guide edges 65a.

[0108] An auxiliary plate-shaped portion 66 is formed at a distance from the plate-shaped portion 61. An auxiliary hole 67 is formed in the portion of the auxiliary plate-shaped portion 66 opposite to the retaining hole 64. A gap is provided between the plate-shaped portion 61 and the auxiliary plate-shaped portion 66 at the periphery of the retaining hole 64, allowing the head 74, which will be described later, to be disposed. The auxiliary plate-shaped portion 66 may also be omitted.

[0109] The embedded fixing part 72 includes an embedded main body part 73 and an embedded state holding pin 77.

[0110] The embedded main body 73 is a component formed of resin or the like, and includes a head 74 and an insertion part 75. The head 74 is formed in the shape of a circular plate. The insertion part 75 is formed in a shape that protrudes from one main surface of the head 74. More specifically, the insertion part 75 is formed in the shape of a cylinder. A plurality of slits 75S are formed in the insertion part 75 along its axial direction. The front end portion 75e of the insertion part 75 is formed in an inwardly facing shape. The insertion part 75 can be deformed in a way that widens its front end side.

[0111] An opening 74h is formed in the head 74. An embedded retaining pin 77 is inserted into the insertion portion 75 through the opening 74h. The embedded retaining pin 77 includes a pin head 78 and a columnar portion 79. The pin head 78 is formed as a circular plate capable of being disposed within the opening 74h. The columnar portion 79 is formed as an elongated shape protruding from the pin head 78. The front end of the pin head 78 is formed as a first guide surface 79a that gradually thickens from the front end side towards the base end side. The middle portion of the pin head 78 in the longitudinal direction is formed as a groove 79b that is recessed inward along its circumference. The front end portion 75e of the insertion portion 75 is inserted into this groove 79b. Furthermore, the base end of the pin head 78 is formed as a second guide surface 79c that gradually tapers from the front end side towards the base end side.

[0112] The auxiliary hole 67 in the aforementioned auxiliary plate-shaped portion 66 is formed to have an outer diameter larger than that of the pin head 78.

[0113] In its initial state, the pin head 78 in the embedded retaining pin 77 protrudes outward compared to the head 74 in the embedded body portion 73. The base end of the insertion portion 75 in the embedded fixing portion 72 is held within the aforementioned retaining hole 64, and the head 74 is positioned between the plate-like portion 61 and the auxiliary plate-like portion 66, thereby supporting the embedded fixing portion 72 on the rigid member 60. In this state, the insertion portion 75 is held in place by the narrow portion between the retaining hole 64 and the guide portion 65, preventing it from falling out of the retaining hole 64.

[0114] When the rigid member 60 is fixed to the frame 13F, the insertion part 75 is inserted into the fixing hole 13Fa formed in the frame 13F. Then, the insertion holding pin 77 is pressed into the insertion body part 73. As a result, the front end 75e of the insertion part 75 is pressed outward from the first guide surface 79a of the pin head 78. Thus, the outward portion of the front end of the insertion part 75 is locked or in contact with the fixing hole 13Fa formed in the frame 13F in a non-detachable manner. The insertion holding pin 77 is pressed in further, and the insertion fixing part 72 is held in the fixing hole 13Fa formed in the frame 13F by inserting the front end 75e of the insertion part 75 into the groove 79b of the pin head 78. In this state, the outward extension of the pin head 78 can also be located on the outward extension line of the head 74. Thus, the pin head 78 is difficult to be accidentally pressed in.

[0115] When the pin head 78 is further pressed in from the above state, the insertion portion 75e of the insertion part 75 is released from the embedded state of the groove portion 79b of the pin head 78, and the insertion portion 75e of the insertion part 75 becomes a state in which it can retract inward relative to the second guide surface 79c of the pin head 78. Thus, the outward portion of the insertion part 75's front end is no longer engaged or in contact with the fixing hole 13Fa, and the embedded fixing part 72 can disengage from the fixing hole 13Fa formed in the frame 13F. With the above structure, the rigid member 60 can be easily installed onto the frame 13F, and it can also be easily disassembled.

[0116] With the wiring module 20 configured in this way, the roof-side device 50 and the conveying member 40 are mounted on the functional sheet 30. Therefore, the wiring module 20, the functional sheet 30, the roof-side device 50, and the conveying member 40 can be easily installed together in the roof portion 14 of the vehicle. However, it is conceivable that the functional sheet 30 might sag due to its own weight. Furthermore, it is conceivable that it might sag due to the weight of the roof-side device 50 mounted on the functional sheet 30 and the weight of the conveying member 40. The wiring module 20 may extend significantly downwards into the roof portion 14; therefore, if a portion of it sags, installation into the roof portion 14 becomes difficult.

[0117] In this wiring module 20, a rigid member 60 is provided in the functional sheet 30. Therefore, the portion of the functional sheet 30 with the rigid member 60 is unlikely to droop. As a result, the wiring module 20 can be easily installed into the roof portion 14 of the carriage.

[0118] For example, Figure 9 This is a schematic diagram showing the location of the wiring module 20 in vehicle 10. Figure 9 The diagram shows the positional relationship at a plane perpendicular to the left and right directions. As shown in the figure, the wiring module 20 is disposed between the interior component 16 and the roof panel 13. Vehicle-side devices 18A and 18B are disposed on the vehicle body side. Vehicle-side devices 18A and 18B are, for example, devices disposed in the vehicle body 12 below the interior component 16. As described above, vehicle-side devices 18A and 18B can be a body ECU, a central ECU, etc., or they can be power supply devices. For example, vehicle-side device 18A is an ECU, and vehicle-side device 18B is a power supply device. A relay transmission component 19 extending from the vehicle-side devices 18A and 18B passes through the A-pillar 11P, etc., and extends between the roof panel 13 and the interior component 16, connecting to the electronic control unit 51. As described above, the relay transmission component 19 can be directly inserted into the electronic control unit 51 or connected via a connector.

[0119] When assembling the wiring module 20 onto the roof panel 13, it is performed as follows: The operator lifts the wiring module 20 from below the roof panel 13 and installs it onto the roof panel 13. At this time, the operator lifts the portion of the wiring module 20 equipped with the rigid member 60 from below (refer to arrow numeral P). Thus, even with fewer support points, the wiring module 20 can be assembled onto the roof panel 13 in a supported state that prevents it from drooping. Therefore, it is easy to assemble the wiring module 20 onto the roof panel 13.

[0120] Furthermore, if the rigid member 60 is provided in the area of ​​the functional sheet 30 where the roof-side equipment (external communication antenna unit 53, lamp 54, camera 55, etc.) is supported, the rigid member 60 can firmly support these roof-side equipment even when they are pressed from the indoor side.

[0121] In addition, if the rigid member 60 is fixed to the roof portion 14 of the carriage via the roof fixing part 70, the rigid member 60 is firmly fixed to the roof portion 14 of the carriage.

[0122] Furthermore, the retaining hole 64 in the rigid member 60 is inserted into the fixing part 72 to support it in a state that allows movement in the direction of expansion of the functional sheet 30. Therefore, when the rigid member 60 in the functional sheet 30 is fixed to the roof portion 14, in the event of manufacturing errors, assembly errors, etc., the position of the inserted fixing part 72 is adjusted corresponding to the position of the fixing hole 13Fa in the frame 13F. Therefore, the inserted fixing part 72 is easily inserted and fixed to the roof panel 13.

[0123] Figure 10 This is a perspective view showing a variation of Embodiment 1. As shown in the figure, in this embodiment, when a functional sheet 30 exists between the roof-side device 50 and the rigid member 60, the roof-side device 50 can also be directly fixed to the rigid member 60. In this example, a fixing piece 152 protrudes from the roof-side device 50, and an opening 131h is formed in the area of ​​the functional sheet 30 corresponding to the fixing piece 152. Furthermore, it is also possible for a fixing member S, such as a screw, to be inserted through the insertion hole 152h formed in the fixing piece 152, and to be fixed to the fixing hole formed in the rigid member 60 by means of threaded fastening or the like through the opening 131h.

[0124] [Implementation Method 2]

[0125] The wiring module group of implementation method 2 is described. Figure 11 This is an exploded perspective view showing the wiring module group 210. Figure 2 The image shows the roof section 14 of the carriage.

[0126] The wiring module group 210 includes a wiring module 20 and an internal component side wiring module 220.

[0127] The wiring module 20 can also be the same structure as the structure described in Embodiment 1 above.

[0128] The internal component-side wiring module 220 is a wiring module installed in the internal component 16. The internal component-side wiring module 220 includes an internal component-side transmission member 240. The internal component-side transmission member 240 may also be the same as the transmission member 40 described above. Here, we will explain the case where the internal component-side transmission member 240 is an electrical wire.

[0129] The interior component side conveying member 240 is connected to a portion of the roof-side equipment 250 installed in the roof section 14. The interior component side conveying member 240 can be directly guided into the roof-side equipment 250 and directly connected to the electrical components inside, or it can be connected via a connector. The roof-side equipment 250 is not fixed to the functional sheet 30. The roof-side equipment 250 can also be fixed to the interior component 16, roof panel 13, frame 13F, etc. Figure 11The image shows an example of a roof-side device 250 being fixed to an interior component 16.

[0130] The interior component-side wiring module 220 can be installed together with the roof-side equipment 250 in the roof section 14, or it can be installed separately from the roof-side equipment 250 in the roof section 14 and connected to the roof-side equipment 250 by a connector in the roof section 14. The interior component-side conveying component 240 can also be fixed to the interior component 16 by adhesive tape, adhesive, etc.

[0131] The internal component side transmission component 240 can also be a separate wiring path from the wiring module 20 described above. For example, the internal component side transmission component 240 can be connected to the vehicle-side equipment via a relay transmission component 219, which is different from the relay transmission component 19 described above.

[0132] According to this embodiment 2, the interior component side conveying member 240 in the interior component side wiring module 220 and the conveying member 40 in the wiring module 20 can be respectively installed in the vehicle roof portion 14. Therefore, it is possible to easily handle differences in grade, the presence or absence of optional components, etc.

[0133] For example, the various roof-side devices installed on the roof section 14 can be categorized into roof-side devices that are installed regardless of the vehicle's class or the availability of options (also known as common roof-side devices, such as map lights), and roof-side devices that are installed or not installed depending on the vehicle's class and the availability of options (also known as optional roof-side devices, such as cameras, interior antennas, etc.). Wiring connected to the former type of roof-side device can be installed in the interior component side wiring module 220 as an interior component side transmission component 240. Wiring connected to the latter type of roof-side device can be installed in the wiring module 20 as a transmission component 40. Thus, by manufacturing the basic specifications of the vehicle using the interior component side wiring module 220, various functional sheets 30 for adding roof-side devices can be easily accommodated.

[0134] It should be noted that the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
