[0021] [Description of embodiments of this disclosure]

[0022] First, embodiments of this disclosure will be described.

[0023] The door wiring module disclosed herein is as follows.

[0024] (1) A door wiring module is assembled into a vehicle door panel having an outer panel and an inner panel. The door wiring module includes multiple wiring components connecting body equipment and door equipment, and an inner path limiting component and an outer path limiting component restricting the paths of the multiple wiring components. The multiple wiring components include an outer limiting path portion disposed between the outer panel and the inner panel and whose path is limited by the outer path limiting component; an inner limiting path portion disposed closer to the interior of the vehicle than the outer limiting path portion and whose path is limited by the inner path limiting component; and a connecting path portion connecting the inner limiting path portion and the outer limiting path portion. The connecting path portion has a bendable portion that is more flexible than the outer limiting path portion. The paths of the inner limiting path portion and the outer limiting path portion can be limited separately by the path limiting component. Furthermore, by providing the bendable portion in the connecting path portion, the inner limiting path portion and the outer limiting path portion can be easily positioned in a predetermined assembly location. This improves the assembly operability of door wiring modules that include both outer and inner limiting path sections.

[0025] (2) In the door wiring module of (1), a branch may be provided at the end of the connection path section connected to the vehicle body equipment, and a window receiving section for storing the open window glass may be provided between the outer panel and the inner panel, with the outer limiting path section extending between the window receiving section and the outer panel. It is conceivable that if the branch is provided at the end of the connection path to the vehicle body equipment, the outer limiting path section becomes longer. In this case, the assembly operability of the outer limiting path section can also be improved.

[0026] (3) In the door wiring module of (2), multiple outer path limiting members may be provided with gaps in the length direction of the wiring member. As a result, folding is possible between the outer path limiting members, and the handling form of the door wiring module can be reduced even if the outer limiting path portion becomes longer.

[0027] (4) In the door wiring module of (1), the wiring component constituting the outer limiting path portion may also constitute the connecting path portion and the inner limiting path portion as it extends from the outer limiting path portion toward the vehicle body side. Thus, in the wiring component constituting the outer limiting path portion, a portion of the path can be limited by the inner path limiting component.

[0028] (5) In the door wiring module of (4), a window receiving portion for accommodating the open window glass may be provided between the outer panel and the inner panel, and the wiring component constituting the outer path restriction portion may bypass the window receiving portion from the rear of the vehicle door panel at at least one of the connecting path portion and the outer path restriction portion. Thus, the wiring component bypassing the window receiving portion from the rear of the door panel can have its path restricted by the outer path restriction component.

[0029] (6) In any of the door wiring modules in (1) to (5), the outer path limiting member may be a sheet, and the wiring members constituting the outer path limiting portion may be held in a state where multiple wiring members are arranged side by side on the sheet. Thus, the outer path limiting portion can be kept flat, thereby enabling the outer path limiting portion to be assembled into the narrow space of the door.

[0030] (7) In the door wiring module of (6), the sheet may also include a first sheet and a second sheet with higher rigidity than the first sheet, and the wiring component is directly fixed to the contact portion of the first sheet. Thus, the sheet can restrict the path of the outer limiting path portion, and the wiring component can be directly fixed to the contact portion of the sheet.

[0031] (8) In the door wiring module of (7), the wiring component may also be sandwiched between the first sheet and the second sheet. Thus, the sheets can protect both sides of the wiring component.

[0032] (9) In any of the door wiring modules in (6) to (8), an adhesive layer may be provided on the sheet. Thus, the sheet can be bonded to the door panel via the adhesive layer, and the outer limiting path portion can be fixed to the door panel.

[0033] (10) In any of the door wiring modules in (1) to (9), the inner path limiting component may be an inspection hole cover that covers the inspection hole formed on the inner plate. As a result, the inspection hole cover and the inner path limiting component can be assembled together, thereby improving the assembly operability of the inner path limiting component.

[0034] (11) In addition, the assembly structure of the door wiring module disclosed herein is an assembly structure of a door wiring module having any one of (1) to (10) a door wiring module and a door panel having said door wiring module assembled thereon.

[0035] [Details of the embodiments disclosed herein]

[0036] The following describes specific examples of the door wiring module and its assembly structure of the present disclosure with reference to the accompanying drawings. Furthermore, the present disclosure is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as indicated by the claims themselves.

[0037] [Implementation Method 1]

[0038] The following describes the door wiring module and its assembly structure according to Embodiment 1. Figure 1 This is a front view showing the door wiring module 30 and the door panel 20 that assembles it according to Embodiment 1. Figure 2 This is a front view showing the assembly structure 1 of the door wiring module according to Embodiment 1. Figure 3 It is along Figure 2 A schematic diagram of the assembly structure 1 of the wiring module for the door with the III-III line cut off. Figure 4 It is along Figure 2 A schematic diagram of the assembly structure 1 of the wiring module for the door with IV-IV line cut-off.

[0039] First, let's describe the general outline of the door 10 in the vehicle. The door 10 is a component that is generally formed into a flat shape and is installed in the vehicle in a way that can be opened and closed to separate the interior and exterior of the vehicle. The door 10 is envisioned as a driver's side door, a passenger side door, a rear seat door, etc. The door 10 includes a door panel 20, an exterior trim piece DT, and a door wiring module 30.

[0040] The door panel 20 includes an outer panel 21 and an inner panel 22. The outer panel 21 is the portion of the door 10 facing outwards from the vehicle and forms the exterior of the vehicle together with the body body. The inner panel 22 is located on the passenger side of the outer panel 21. The inner panel 22 has a side panel portion 23 and a main panel portion 25. The side panel portion 23 is a portion that protrudes from the outer panel 21 toward the passenger interior. The main panel portion 25 is a portion that connects to the side panel portion 23, is spaced apart from the outer panel 21, and extends along the outer panel 21. A space is formed between the outer panel 21, the main panel portion 25, and the side panel portion 23. A door device or a receiving window glass WP provided on the door 10 is disposed in this space. An access hole 26 is provided on the main panel portion 25 of the inner panel 22. An operator can enter the space between the outer panel 21 and the inner panel 22 from the outside of the inner panel 22 through the access hole 26.

[0041] The exterior design trim piece DT is the part located in the door 10 facing the interior of the vehicle and constitutes the interior appearance of the vehicle. Examples of exterior design trim pieces DT include interior handles and operating parts for in-vehicle equipment.

[0042] The door wiring module 30 includes a wiring component 40, an inner path limiting component 50, and an outer path limiting component 60.

[0043] Wiring component 40 connects the door device to body equipment installed on the vehicle body, supplies power to the door device, and transmits signals between the door device and the body equipment. Wiring component 40 may also include wire 41. As wire 41, a sheathed wire (see reference) in which a sheathing layer 43 is formed around a core wire 42 composed of conductors can be used. Figure 5 The core wire 42 can be either a single-core wire or a stranded wire. The type of wire 41 is not particularly limited and can include single-wire, composite wire, etc. A single-wire wire is a wire with one conductive circuit. A composite wire is a wire with multiple conductive circuits. As a composite wire, it can also be a wire formed by combining multiple single wires, such as twisted-pair or composite cables. The wiring component 40 may also include optical fiber cables, etc.

[0044] Multiple wiring components 40 are provided. The paths of the multiple wiring components 40 are appropriately set according to the specifications of the door 10. For example, in the case of a typical hinged door where the rotation axis is along the height direction of the vehicle, the multiple wiring components 40 assembled to the hinged door are usually connected to the vehicle body near the door hinge, and branch out from the door hinge side to the side opposite to the door hinge to connect to various door devices.

[0045] More specifically, imagine that one end of multiple wiring components 40 is in a bundled state, passing through a portion of door 10 (in Figure 1 In the example shown, the side panel 23 on the hinge side extends from the door 10, is guided into the vehicle body, and connects via a common connector C1 or the like to body equipment or a relay connector located at the end of a wiring component extending from the body equipment. The aforementioned body equipment is not particularly limited; for example, an electronic control unit (ECU) or a battery is envisioned. A typical retaining ring G1 is installed on the portion of the plurality of wiring components 40 extending between the door 10 and the vehicle body. Figure 1 In the example shown, the retaining ring G1 is a so-called through-hole type retaining ring that is inserted and locked into the through hole 24 formed in the side plate portion 23. Thus, water intrusion through the through hole 24 is suppressed. Multiple wiring components 40 extend from the retaining ring G1, branching out and extending towards the door devices that become their respective connection targets, as they extend from one end to the other. At the other end of the multiple wiring components 40, connectors C2, C3, and C4 corresponding to the door devices that become their connection targets are installed. Each connector C2, C3, and C4 connects to, for example, connectors C5, C6, and C7 on the door device side. Figure 1 and Figure 2 The example shows connectors C5, C6, and C7 on the three door device sides, and wires 41A, 41B, and 41C connected to connectors C5, C6, and C7 via connectors C2, C3, and C4.

[0046] Connector C5 is, for example, a connector for an actuator used to lock and unlock door 10. Connector C6 is, for example, a connector for a foot light. Connector C7 is, for example, a connector for a door device installed on the outer handle. As a door device installed on the outer handle, one or more of the following are conceived: a sensor for detecting the opening and closing of a key, a sensor for detecting the operation of the outer handle, an antenna device for transmitting and receiving signals between itself and an antenna device on the key side, a switch installed on the outer handle, etc.

[0047] exist Figure 1 and Figure 2 In the case of door 10, the description of connectors and wiring components other than connectors C5, C6, and C7 on the three door device sides and the wires 41A, 41B, and 41C connected to them is omitted. Of course, the door wiring module 30 may also include wiring components other than the wires 41A, 41B, and 41C connected to connectors C5, C6, and C7 on the three door device sides.

[0048] Multiple wiring components 40 are modularized in a manner that includes an inner limiting path portion 44, an outer limiting path portion 45, and a connecting path portion 46. The inner limiting path portion 44, the outer limiting path portion 45, and the connecting path portion 46 typically each contain multiple wires 41.

[0049] The inner path limiting portion 44 is located closer to the interior side of the inner panel 22. Furthermore, the inner path limiting portion 44 is the portion whose path is limited by the inner path limiting member 50. Figure 1 In the example shown, the inner limiting path portion 44 is a part of the path of the wire 41A connected to the door lock and unlocking actuator and the wire 41B connected to the foot lamp. Alternatively, the inner limiting path portion 44 can also be a part of the path of wiring components exposed into the vehicle interior, such as wiring components for switches, wiring components for the actuators of the door mirrors 10. Limiting the path of wiring component 40 means maintaining the path of wiring component 40 as a predetermined path.

[0050] The outer path-limiting portion 45 is disposed between the outer panel 21 and the inner panel 22. Furthermore, the outer path-limiting portion 45 is the portion whose path is limited by the outer path-limiting member 60. Figure 1 In the example shown, the outer limiting path portion 45 is a path for part of the wire 41C for the outer handle. Alternatively, the outer limiting path portion 45 can also be a path for part of wiring components for a speaker, wiring components for the actuator of a window regulator WR, etc.

[0051] The connecting path portion 46 connects the inner limiting path portion 44 and the outer limiting path portion 45. The connecting path portion 46 has a bendable portion 47. The bendable portion 47 is more flexible than the portion of the outer limiting path portion 45 where the outer path limiting member 60 is located. For example, if the wiring component 40 is a single unit, it is a component that is flexible in all radial directions. The outer path limiting member 60 is designed to be less flexible in at least one radial direction of the wiring component 40. The bendable portion 47 is preferably flexible in all radial directions. Radially, the bendable portion 47 can be bent in more directions than the outer limiting path portion 45. The bendable portion 47 may also be provided with a component of uniformly low rigidity, such as tape, sheet, or rubber. The bendable portion 47 may also be provided with a locally flexible shape, such as the pleats of a bellows. For example, the bendable portion 47 may also be provided in the portion of a bundle where multiple wiring components 40 are bundled by a bundling member. In this case, the bundling component preferably bundles the multiple wiring components 40 in a flexible manner.

[0052] The bundling component can also be, for example, a bundling tape. The dimension of the bundling tape along the length of the wiring component 40 is a shorter dimension (e.g., shorter than the dimension along the width of the wiring component 40). Therefore, the portion where the bundling tape is provided along the length of the wiring component 40 can be considered partial, so the bundling tape can be viewed as bundling multiple wiring components 40 in a flexible manner. Alternatively, the bundling component can also be, for example, a flexible component such as a tape T, a flexible sheet, or a corrugated tube, that can follow the bending of the wiring component 40 even when wound around it. In this case, the dimension of the portion where the flexible bundling component is provided along the length of the wiring component 40 can also be a longer dimension than the dimension along the width of the wiring component 40. Figure 1 In the example shown, multiple wiring components 40 are bundled together by spirally winding tape T.

[0053] Here, a branch 48 is provided in the connecting path portion 46. A retaining ring G1 is provided between the branch 48 and the connector C1. If we observe the travel of the multiple wiring components 40 extending from the vehicle body to the door 10, at the branch 48 extending from the retaining ring G1, the multiple wiring components 40 branch into wires 41A and 41B constituting the inner limiting path portion 44 and wires 41C constituting the outer limiting path portion 45. If we observe the travel of the multiple wiring components 40 extending from the door 10 to the vehicle body, the wires 41A and 41B constituting the inner limiting path portion 44 and the wire 41C constituting the outer limiting path portion 45 converge at the branch 48 and extend towards the retaining ring G1. Here, the portion of the connecting path portion 46 closer to the door 10 than the portion where the retaining ring G1 is provided is similarly disposed in the space between the outer panel 21 and the inner panel 22 in the outer limiting path portion 45.

[0054] The bendable portion 47 is preferably located between at least the outer limiting path portion 45 and the branch portion 48 in the connecting path portion 46. Figure 1 In the example shown, the portion between the retaining ring G1 and the branch 48 in the connecting path portion 46, the portion between the inner limiting path portion 44 and the branch 48, and the portion between the outer limiting path portion 45 and the branch 48 are all designed as flexible portions 47. Therefore, in Figure 1 In the example shown, the inner limiting path portion 44 and the outer limiting path portion 45 in the connecting path portion 46 are uniformly provided as a flexible portion 47.

[0055] The wires 41A and 41B forming the inner limiting path portion 44 extend from the portion where the retaining ring G1 is provided to the connectors C2 and C3, passing through the inner panel 22 and moving towards the interior side of the inner panel 22. The wires 41A and 41B are divided into the inner limiting path portion 44 and the connecting path portion 46, with the portion passing through the inner panel 22 as the boundary. Relative to the portion of the wires 41A and 41B that passes through the inner panel 22, the door equipment side is designated as the inner limiting path portion 44, and the body equipment side is designated as the connecting path portion 46. Here, the wires 41A and 41B pass through the access hole 26 and move towards the interior side of the inner panel 22. However, the wires 41A and 41B may also pass through holes other than the access hole 26 and move towards the interior side of the inner panel 22.

[0056] The wire 41C, constituting the outer limiting path portion 45, extends from the retaining ring G1 to the connector C4, and is integrally disposed in the space between the outer panel 21 and the inner panel 22. A window receiving portion 27 is disposed between the outer panel 21 and the inner panel 22. The window receiving portion 27 is the portion that houses the window glass WP in the open state. The open state is the state where the window glass WP is lowered to its maximum, and it is not necessary to house the entire area of ​​the window glass WP within the window receiving portion 27. The window receiving portion 27 is formed in the gap between the outer panel 21 and the inner panel 22. A portion of the wire 41C, which is configured as a flexible portion 47, extends from the front of the door 10, bypassing the window receiving portion 27, and extends between the window receiving portion 27 and the outer panel 21 as part of the outer limiting path portion 45.

[0057] The inner path limiting member 50 is a component that limits the path of the inner path limiting portion 44. The inner path limiting member 50 can be a planar component or a protective component, etc. Preferably, the planar component, like the inner panel 22, is configured to extend along the longitudinal and vertical directions of the vehicle. This planar component can also be a access cover 50 or a sound insulation plate, etc. Hereinafter, we will describe the inner path limiting member 50 as an access cover 50. Furthermore, the inner path limiting member 50 is preferably a rigid component that is difficult to bend. When the inner path limiting member 50 is a planar component, it can be difficult to bend about an axis perpendicular to the main surface, or it can be a flexible component that is easy to bend about an axis parallel to the surface.

[0058] A manhole cover 50 covers the manhole 26. The manhole cover 50 is a flat resin component that is the same size as or significantly larger than the manhole 26. The manhole cover 50 is installed to block the manhole 26. Thus, the manhole cover 50 separates the inner and outer sides of the vehicle. With the manhole cover 50 installed in the manhole 26 of the inner panel 22, this installation is maintained by threaded locking, locking mechanisms, or adhesive bonding. For example, if the portion of the manhole cover 50 that overlaps with the inner panel 22 is bonded to the inner panel 22, the gap between them can be blocked as much as possible.

[0059] The access cover 50 separates the interior side of the space between the outer panel 21 and the inner panel 22. This space houses the window glass WP, which is exposed to rain, and a slit-like opening is formed above this space for the window glass WP to enter and exit. Therefore, this space is a potential source of water intrusion. Furthermore, since this space may connect to the outside environment, it is also a potential source of external wind noise and other disturbances. Therefore, the access cover 50 is preferably provided as a component that, together with the inner panel 22, more completely separates the interior space from the exterior space. More specifically, the access cover 50 includes a cover body 51, a frame 52, and a flange 53. Here, the access cover 50 is a component molded from a resin such as polypropylene (PP), possessing rigidity that is difficult to bend. However, the access cover 50 may also be a waterproof membrane or the like.

[0060] The cover body 51 is a plate-shaped portion that extends slightly smaller than the access hole 26. The frame portion 52 is formed to protrude from the outer edge of the cover body 51 toward one main surface side (inside the vehicle interior) of the cover body 51. The flange portion 53 is formed to extend from the outer edge of the frame portion 52 toward the outer periphery. The frame portion 52 is formed as an inclined surface whose height dimension gradually decreases from the flange portion 53 toward the cover body 51. When the access hole cover 50 is installed in the predetermined position of the access hole 26 of the inner panel 22, the cover body 51 is disposed inside the access hole 26 (between the main panel 25 and the outer panel 21), the flange portion 53 is disposed outside the access hole 26 (between the main panel 25 and the inside of the vehicle interior), and the frame portion 52 connects the two. Thus, the opening edge of the cover body 51 and the periphery of the access hole 26 are blocked by the frame portion 52 and the flange portion 53.

[0061] Furthermore, a through hole 54 is formed in the access cover 50 for the wiring component 40 to pass through. Wires 41A and 41B pass through this through hole 54 and the access hole 26, thus penetrating the access cover 50 and the inner plate 22. The through hole 54 is preferably formed in the cover body portion 51 or the frame portion 52 of the access cover 50. Here, the through hole 54 is formed in the frame portion 52. In particular, here, the through hole 54 is formed at the end of the slot 55 (described later) in the frame portion 52. Thus, the wiring component 40 housed in the slot 55 can pass through the through hole 54 and penetrate the access cover 50.

[0062] There is no particular limitation on the fixing method of the wiring component 40 to the inspection hole cover 50. For example, it can also be fixed by contact part or non-contact part.

[0063] Here, contact fixation refers to the state in which the wiring component 40 and the fixing object are held together and fixed by means of adhesive bonding at the contacting parts. Contact fixation can take the form of either indirect or direct fixation. Indirect fixation means that the wiring component 40 and the fixing object are indirectly bonded together via an intermediary component such as an adhesive, bonding agent, or double-sided tape. Direct fixation means that the wiring component 40 and the fixing object are directly bonded together without the use of a separate adhesive. In direct fixation, for example, it is envisioned that the resin contained in at least one of the wiring component 40 and the fixing object melts and bonds to the object-side component.

[0064] Non-contact fixation refers to a fixation method that does not involve contact. For example, the wiring component 40 is pressed into the fixed object by sewing, other sheets, tape, etc., or the sewing, other sheets, tape, etc. are arranged around the wiring component 40 and the fixed object to clamp the wiring component 40 and the fixed object, thus maintaining the state in which the wiring component 40 and the fixed object are fixed.

[0065] Here, the wiring component 40 is fixed to the access cover 50 using a non-contact fixing method. When the wiring component 40 is fixed to the access cover 50 using this non-contact fixing method, grooves 55, 56, and 57 formed in the access cover 50 are used. Grooves 55, 56, and 57 are formed on a main surface of the cover body 51. With at least a portion of the wiring component 40, which constitutes the inner limiting path portion 44, extending in the direction of extension, accommodated within the grooves 55, 56, and 57, the wiring cover 58 covers the top of the grooves 55, 56, and 57, thereby preventing the wiring component 40 from falling off. Furthermore, Figure 2 Slots 55, 56, 57 and wiring cover 58 are omitted from the drawing.

[0066] More specifically, slots 55, 56, and 57 are formed along the path of the inner limiting path portion 44 relative to the access cover 50. Slot 55 is formed from the front to the rear of the access cover 50 in the vehicle's longitudinal direction. Viewed from the passenger compartment side, slot 55 is formed as a straight line extending in the vehicle's longitudinal direction. Slots 56 and 57 branch from the ends of slot 55. Slot 56 is formed as a straight line extending in the vehicle's longitudinal direction. Slot 57 is formed as a straight line extending in the vehicle's height direction.

[0067] The wires 41A and 41B constituting the inner limiting path portion 44 branch off at their branch portions 48 on the access cover 50, splitting from a main line into two branch lines. The main line is the portion where wires 41A and 41B run parallel. The two branch lines are individual extensions of wires 41A and 41B. The main line is housed in a slot 55, and the two branch lines are housed in slots 56 and 57, respectively. Slots 55 and 56 can be used to hold wires 41A connected to door devices installed at the rear of the door 10, such as door locks and unlocking actuators. Slots 55 and 57 can be used to hold wires 41B connected to door devices installed at the lower part of the door 10, such as footlights.

[0068] Each slot 55, 56, and 57 is sized to accommodate multiple wiring components 40 in a concentrated manner. Each slot 55, 56, and 57 is flat, with its width dimension being larger than its depth dimension. Multiple slots 55, 56, and 57 can also be formed side-by-side, each capable of accommodating multiple wires separately. For example, multiple slots can also be formed side-by-side, each sized to accommodate wires individually.

[0069] The wiring cover 58 can also be formed, for example, in the form of a plate, and disposed on the upper part of the slots 55, 56, and 57 in a manner that spans the slots 55, 56, and 57. The wiring cover 58 can also be fixed to the access cover 50 by bonding or welding at the side edge of the slots 55, 56, and 57.

[0070] The outer path limiting member 60 is a member that limits the path of the outer path limiting portion 45. Regarding the outer path limiting portion 45 on which the outer path limiting member 60 is provided, besides... Figures 1 to 4 In addition, refer to Figure 5 Please provide an explanation. Figure 5 This is a cross-sectional view showing the outer limiting path portion 45.

[0071] Here, the outer path limiting member 60 is described as a sheet 60. Multiple wiring components 40 are held in a side-by-side configuration on the sheet 60. Specifically, the multiple wiring components 40 are held in a row on the sheet 60. The multiple wiring components 40 are arranged linearly on the sheet 60. The sheet 60 includes a first sheet 62 and a second sheet 64. The wiring components 40 are sandwiched between the first sheet 62 and the second sheet 64.

[0072] The fixing method of the wiring component 40 to the sheet 60 is not particularly limited. Similar to the fixing method of the wiring component 40 to the access cover 50, for example, fixing by contact points or fixing by non-contact points can also be used. Here, fixing by contact points is used as the fixing method of the wiring component 40 to the sheet 60.

[0073] The wiring component 40 is fixed only to the first sheet 62 of the first sheet 62 and the second sheet 64 through a contact portion. The wiring component 40 is not fixed to the second sheet 64 through a contact portion. The second sheet 64 is fixed to the first sheet 62. Therefore, the second sheet 64 is fixed to the wiring component 40 via the first sheet 62. The fixing method between the first sheet 62 and the second sheet 64 is not particularly limited; contact portion fixing, non-contact portion fixing, etc., can also be used. The fixing method between the first sheet 62 and the second sheet 64 can be the same as or different from the fixing method between the wiring component 40 and the first sheet 62.

[0074] The wiring component 40 is directly fixed to the contact area with the first sheet 62. In this case, either only the resin contained in the sheathing layer 43 of the wiring component 40 or only the resin contained in the first sheet 62 can be melted. In these cases, sometimes the resin of one side becomes bonded to the outside of the other side, forming a relatively clear interface. Alternatively, both the resin contained in the sheathing layer 43 of the wiring component 40 and the resin contained in the first sheet 62 can be melted. In this case, sometimes the resins of both sides are mixed and do not form a clear interface. The resin contained in the sheathing layer 43 of the wiring component 40 and the resin contained in the first sheet 62 are preferably formed from a material that allows for direct fixing at the contact area, such as the same resin material. For example, both the sheathing layer 43 and the first sheet 62 of the wiring component 40 can be made of polyvinyl chloride (PVC) or polyethylene (PE).

[0075] At this time, there is no particular limitation on the means of forming a directly fixed contact area, and various means, including known means such as welding, can be used. For example, in the case of welding, various welding methods such as ultrasonic welding, heat and pressure welding, hot gas welding, and high-frequency welding can be used. Furthermore, if the directly fixed contact area is formed by these means, then the first sheet 62 and the wiring component 40 are set to a state of directly fixed contact area achieved by such means. Specifically, for example, if the directly fixed contact area is formed by ultrasonic welding, then the first sheet 62 and the wiring component 40 are set to a state of directly fixed contact area achieved by ultrasonic welding. The part that forms a directly fixed contact area by welding can also be called the welded part, and the fixed part achieved by ultrasonic welding can be called the ultrasonic welded part, etc.

[0076] The fixing portion FP1 (here, the fusion joint) of the first sheet 62 and the wiring component 40 can also be continuously provided throughout the length direction of the wiring component 40. Alternatively, the fixing portion FP1 can be provided intermittently throughout the length direction of the wiring component 40. That is, multiple point fixing portions, partially provided along the length direction of the wiring component 40, can be provided with gaps along the length direction of the wiring component 40. The same applies to the fixing portion FP2 of the first sheet 62 and the second sheet 64.

[0077] The second sheet 64 has higher rigidity than the first sheet 62. Preferably, the second sheet 64 has higher rigidity than the wiring component 40. For example, the first sheet 62 can be a flexible sheet made of PVC, and the second sheet 64 can be a difficult-to-bend sheet made of PP. By providing the second sheet 64, the outer limiting path portion 45 is difficult to bend in any direction.

[0078] Multiple sheets 60 (two in this case) are provided with gaps along the length of the wiring components 40. The multiple wiring components 40 are designed to be easily folded between the sheets 60. Since the multiple wiring components 40 are held side-by-side on each sheet 60, they are also held side-by-side between the sheets 60. Therefore, the two sheets 60 can be easily folded in an overlapping manner. Furthermore, here, the outer path limiting member 60 on the connector C4 side of the wire 41C, similar to the bendable portion 47 in the connection path portion 46, is also designed as a bendable portion. Therefore, when connecting the connector C4 to the connector C7, the end of the wire 41C can be easily arranged.

[0079] A fixing part for fixing to the door panel 20 is provided on the outer limiting path portion 45. Figure 5 In the example shown, the fixing part is adhesive layer 66. Adhesive layer 66 is provided on sheet 60. By bonding adhesive layer 66 provided on sheet 60 to door panel 20 (here, the interior-facing side of outer panel 21), the outer limiting path portion 45 is fixed to door panel 20. Furthermore, here, the outer limiting path portion 45 is fixed to a reinforcing member 28 provided on the inner side of outer panel 21 in door panel 20 via adhesive layer 66. Adhesive layer 66 bonds sheet 60 to reinforcing member 28. Reinforcing member 28 is, for example, a member that suppresses recesses in outer panel 21. Reinforcing member 28 extends along the front-rear direction of door 10. For example, reinforcing member 28 includes a foot and a protrusion connected to the foot. The foot is a portion welded to outer panel 21. The protrusion extends in a manner separate from outer panel 21. Adhesive layer 66 is bonded to the protrusion. Adhesive layer 66 may also be bonded to the foot.

[0080] The adhesive layer 66 can be disposed on the side of the sheet 60 facing the wiring component 40, or on the side opposite to the side facing the wiring component 40. The adhesive layer 66 can be disposed on either the first sheet 62 or the second sheet 64. Figure 5 In the example shown, adhesive layer 66 is disposed on the back side of the second sheet 64, which is the first sheet 62 and the second sheet 64. When transporting the door wiring module 30 from the manufacturing plant to the assembly plant for the door panel 20, a release liner is preferably disposed on the surface of adhesive layer 66. In the assembly plant, it is preferable to peel off the release liner and then bond adhesive layer 66 to the door panel 20.

[0081] Furthermore, this disclosure can also be understood as an assembly structure 1 of the door wiring module 30 having a door wiring module 30 and a door panel 20 on which the door wiring module 30 is assembled.

[0082] <Effects of Implementation Method 1, etc.>

[0083] According to the door wiring module 30 and its assembly structure 1 configured as described above, the inner path limiting portion 44 and the outer path limiting portion 45 can each have their paths limited by path limiting members. Furthermore, by providing a bendable portion 47 in the connecting path portion 46, the inner path limiting portion 44 and the outer path limiting portion 45 can be easily positioned in a predetermined assembly location. Thus, the assembly operability of the door wiring module 30, including the outer path limiting portion 45 and the inner path limiting portion 44, can be improved.

[0084] More specifically, in the door wiring module 30, the components for fixing to the door panel 20 include an inner limiting path portion 44, an outer limiting path portion 45, and a retaining ring G1. During the fixing process, the outer limiting path portion 45 is typically fixed first. At this time, the connecting path portion 46 between the inner limiting path portion 44 and the outer limiting path portion 45 has a bendable portion 47, allowing the base end of the connecting path portion 46 on the outer limiting path portion 45 to be easily positioned at the fixing location. Furthermore, the outer limiting path portion 45 is limited by the outer path limiting member 60, so when the base end of the connecting path portion 46 on the outer limiting path portion 45 is positioned at the fixing location, this front end can be easily positioned at the fixing location. Therefore, the outer limiting path portion 45 can be easily fixed to the door panel 20.

[0085] Furthermore, in the case where the retaining ring G1 is of the type that penetrates the side panel portion 23, the outer restricting path portion 45 and the retaining ring G1 are fixed to the door panel member 20 through the access hole 26. At this time, there is a bendable portion 47 between the branch portion 48 and the outer restricting path portion 45, so that when one of the outer restricting path portion 45 and the retaining ring G1 is fixed to the door panel member 20 first, the other of the outer restricting path portion 45 and the retaining ring G1 can be easily positioned at the fixing position.

[0086] Furthermore, with the branch 48 located at the end of the connecting path portion 46 that connects to the vehicle body equipment, it is envisioned that the wire 41C passes from the front of the door 10 around the window receiving portion 27, thus lengthening the outer restricting path portion 45. Additionally, since the outer restricting path portion 45 extends between the window receiving portion 27 and the outer panel 21, it is envisioned that work through the access hole 26 would be difficult. In this case, by restricting the path of the outer restricting path portion 45 with the outer path restricting member 60 and providing a bendable portion 47 in the connecting path portion 46, the assembly operability of the outer restricting path portion 45 can be improved.

[0087] In addition, multiple outer path limiting members 60 are provided with gaps. As a result, the door wiring module 30 can be folded between the outer path limiting members 60, and the handling configuration of the door wiring module 30 can be reduced even if the outer path limiting portion 45 becomes longer.

[0088] Furthermore, the outer path limiting member 60 is a sheet 60, and the wiring members 40 constituting the outer path limiting portion 45 are held in a state where multiple wiring members 40 are arranged side by side on the sheet 60. As a result, the outer path limiting portion 45 can be kept flat, thereby enabling the outer path limiting portion 45 to be assembled into the narrow space of the door 10.

[0089] Additionally, the sheet 60 includes a first sheet 62 to which the wiring component 40 is fused and a second sheet 64 with higher rigidity than the first sheet 62. Thus, the sheet 60 can restrict the path of the outer limiting path portion 45 and fuse the wiring component 40 to the sheet 60.

[0090] Additionally, the wiring component 40 is sandwiched between the first sheet 62 and the second sheet 64. Thus, at the outer path restriction portion 45, both sides of the wiring component 40 can be protected by the sheet 60.

[0091] In addition, an adhesive layer 66 is provided on the sheet 60, so the sheet 60 can be bonded to the door panel 20 via the adhesive layer 66, and the outer limiting path portion 45 can be fixed to the door panel 20.

[0092] Here, the outer limiting path portion 45 can also be fixed to the door panel 20 by clips. When fixing the outer limiting path portion 45 to the door panel 20 by clips, a hole needs to be made on the door panel 20 side for the clip to be inserted and locked. This hole is considered to be made in, for example, a protrusion of the reinforcing member 28. Due to the making of the hole, the rigidity of the reinforcing member 28 may decrease. In this case, in order to obtain the rigidity required for the reinforcing member 28 after the rigidity decreases due to the formation of the hole, a material with high rigidity can be used as the material of the reinforcing member 28, or the reinforcing member 28 can be formed larger.

[0093] In contrast, in the door wiring module 30, the outer limiting path portion 45 can be fixed to the door panel 20 via the adhesive layer 66, thus eliminating the need for holes for clip insertion on the door panel 20 side and suppressing a decrease in rigidity on the door panel 20 side. Therefore, as a reinforcing member 28, the use of a high-rigidity material for the reinforcing member 28 can be prevented, or the reinforcing member 28 can be formed in a larger size, thus suppressing cost increases.

[0094] Furthermore, the inner path limiting component 50 is an access hole cover 50 that covers the access hole 26 formed on the inner plate 22. As a result, the access hole cover 50 and the inner path limiting portion 44 can be assembled together, thereby improving the assembly operability of the inner path limiting portion 44.

[0095] [Implementation Method 2]

[0096] This describes the door wiring module involved in Implementation Method 2. Figure 6 This is a front view showing the door wiring module 130 and the door panel 120 that assembles it according to Embodiment 2. Figure 7 This is a schematic diagram of the assembly structure of a wiring module for a door. Furthermore, in the description of this embodiment, structural elements that are the same as those previously described are given the same reference numerals, and their descriptions are omitted.

[0097] In the door wiring module 130, the paths of the multiple wiring components 40 are different from those in the door wiring module 30 described above. Specifically, the wire 41C for the outer handle passes around the window receiving portion 27 from the rear of the door 10 and extends between the window receiving portion 27 and the outer panel 21. The wire 41C for the outer handle forms an outer limiting path portion 145 in one section. In addition, in other sections along the route of the wire 41C for the outer handle extending from this one section toward the vehicle body side, i.e., toward the connector C1, it forms a connecting path portion 146 and an inner limiting path portion 144. Thus, at the wire 41C that forms the outer limiting path portion 145, a portion of the path can be limited by the inner path limiting component 50.

[0098] The electrical wire 41C for the outer handle passes around the window receiving portion 27 from the rear of the door panel 20 at least on either the outer path limiting portion 145 or the connecting path portion 146. Thus, the wiring component 40 passing around the window receiving portion 27 from the rear of the door panel 20 can have its path limited by the outer path limiting component 160. Passing around the window receiving portion 27 means traversing horizontally from one of the inner panel 122 to the other, bypassing the window receiving portion 27, within the space between the outer panel 21 and the inner panel 122.

[0099] Furthermore, the door wiring module 130 differs from the door wiring module 30 in that the outer path limiting member 160 is a protective member 160. The outer handle wire 41C's path is limited by the protective member 160 at the outer path limiting portion 145. Additionally, the outer handle wire 41C is bundled at the connecting path portion 146 by a binding member such as tape T, forming a flexible portion 147. However, at the connecting path portion 146, a portion may be a flexible portion 147, while another portion may not be. This other portion can be made difficult to bend, for example, by providing a member with higher rigidity than the flexible portion 147. The outer handle wire 41C passes through the access hole 26 and the insertion hole 54 of the frame portion 52, and then through the inner panel 122 and the access hole cover 50. At the inner path limiting portion 144, the outer handle wire 41C is housed in the same slots 55 and 56 as the wire 41A for the door lock device.

[0100] Furthermore, in the door wiring module 130, the type of retaining ring G2 is different from that of the retaining ring G1 in the door wiring module 30 described above. The retaining ring G2 is a so-called non-penetrating type retaining ring that can be installed at the corner of the side plate portion 23 and the main plate portion 25 in the inner panel 122. In this case, multiple wiring components 40 are integrally arranged from the retaining ring G2 to the inner limiting path portion 144 at a position closer to the interior side of the inner panel 122 than the inner panel 122. Moreover, the wire 41C for the outer handle branches off from the inner panel 122 along with other wires 41A and 41B, passes through the access cover 50 and the inner panel 122, and extends between the outer panel 21 and the inner panel 122.

[0101] The path of the wire 41C for the outer handle can also be a combination of a non-penetrating retaining ring G2 and a path that passes around the window receiving portion 27 from the front of the door 10. In this case, the wire 41C, like the door wiring module 130, emerges from the non-penetrating retaining ring G2, passes through the access cover 50 and the inner panel 122, and, like the door wiring module 30, passes around the window receiving portion 27 from the front of the door 10 via the connecting path portion 46, extending between the window receiving portion 27 and the outer panel 21.

[0102] The path of the wire 41C for the outer handle can also be a combination of a through-type retaining ring G1 and a path that passes around the window receiving portion 27 from the rear of the door 10. In this case, the wire 41C for the outer handle, like the door wiring module 30, emerges from the through-type retaining ring G1, passes through the inner panel 22 and the access cover 50, and like the door wiring module 130, passes through the inner panel 22 again via the inner limiting path portion 44 and the connecting path portion 46, and passes around the window receiving portion 27 from the rear of the door 10, extending between the window receiving portion 27 and the outer panel 21.

[0103] [Variation Example]

[0104] Figure 8 This is a cross-sectional view showing a modified example of the outer limiting path portion 45.

[0105] In Embodiment 1, the wiring component 40 is described as being sandwiched between the first sheet 62 and the second sheet 64, but this is not a necessary structure. Figure 8 As shown, the second sheet 64 can also be laminated on the side of the first sheet 62 opposite to the side of the fixed wiring component 40.

[0106] In addition, the description up to this point has assumed that sheet 60 includes a first sheet 62 and a second sheet 64, but this is not a necessary structure. Sheet 60 may also omit either the first sheet 62 or the second sheet 64. When the first sheet 62 is omitted, the wiring component 40 is preferably fixed to the second sheet 64 by means of contact fixing or non-contact fixing. When the second sheet 64 is omitted, sheet 60 may sometimes be composed only of the flexible first sheet 62. Even in this case, by holding multiple wiring components 40 in a side-by-side state on the first sheet 62, the outer limiting path portion 45 becomes difficult to bend in a direction parallel to the main surface of sheet 60.

[0107] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
