Description

Technical Field

[0001] The present disclosure relates to a wiring module. Background Art

[0002] A grommet is usually mounted on a wiring component that connects a vehicle door to a vehicle body. As an assembly structure between the grommet and a door panel, there are, for example, a structure in which the grommet passes through a through-hole formed in the door panel as described in Patent Document 1 and a structure in which the grommet is arranged along the surface of the door panel as described in Patent Document 2. The grommet described in Patent Document 2 does not need to pass through a through-hole formed in the door panel like the grommet described in Patent Document 1, and is therefore also referred to as a non-through grommet or the like.

[0003] Moreover, a portion of the wiring component that connects the vehicle door to the vehicle body and is arranged along the vehicle door is arranged along a predetermined path corresponding to the position of equipment or the like. At this time, Patent Document 3 discloses a technique of holding a portion of the wiring component arranged along the vehicle door in a state of being along a predetermined path by a mounting part that extends in a planar shape along the door panel.

[0026] [Description of Embodiments of the Present Disclosure]

[0027] First, embodiments of the present disclosure will be listed and described.

[0028] The wiring module of the present disclosure is as follows.

[0029] (1) A wiring module, comprising: a wiring component that connects between a vehicle body and a door panel; a planar component that holds a portion of the wiring component that extends along an inner panel portion of the door panel; and a grommet that is installed at a portion of the wiring component closer to the vehicle body side than the portion held by the planar component. The planar component includes: a main board portion that holds an interval of the wiring component that extends along the inner panel portion of the door panel; and a planar component side mounting portion that is provided at a part of the periphery of the main board portion and is installed on the grommet. The grommet includes: a base portion that is fixed to the door panel at a fixed position; and a grommet side mounting portion that is connected to the base portion and is for installing the planar component side mounting portion. By installing the grommet and the planar component, when one of the grommet and the planar component is positioned on the door panel, the other can also be positioned on the door panel. Thus, in a wiring module having both a grommet and a planar component in the wiring component, the assemblability to the door panel can be improved.

[0030] (2) In the wiring module of (1), it is preferable that the grommet is assembled on the surface of the door panel, and the base portion is fixed to the surface of a side panel portion of the door panel. Thus, the grommet is a non-through grommet, and the wiring module can be simply assembled on the door panel.

[0031] (3) In the wiring module of (2), it is preferable that the main board portion and the planar component side mounting portion are assembled on the surface of the door panel. Thus, in addition to the grommet, the planar component is also a component assembled on the surface of the door panel. Thus, when assembling the wiring module on the door panel, it can be assembled without performing an operation of passing the wiring component through the door panel.

[0032] (4) In the wiring module of (3), it is preferable that the planar component side mounting portion extends from the inner panel portion of the door panel to the side panel portion, and the grommet side mounting portion is provided on a surface of the base portion facing the side panel portion. Thus, a portion of the wiring component that extends between the inner panel portion and the side panel portion is guided by the planar component side mounting portion.

[0033] (5)In the wiring module of (4), it is possible that in the vehicle, a weatherstrip crosses the surface of the base portion, and the planar member side mounting portion extends to a portion of the base portion that overlaps with the weatherstrip. Thus, the planar member side mounting portion can support the portion of the base portion that overlaps with the weatherstrip. The flattening manner of the weatherstrip in the closed state of the vehicle door is stable.

[0034] (6)In the wiring module of (4) or (5), it is possible that a through portion through which the wiring component passes is formed in the planar member side mounting portion. Near the main board portion side with respect to the through portion in the wiring component, the planar member side mounting portion is located closer to the vehicle door panel side than the wiring component. Near the vehicle body side with respect to the through portion in the wiring component, the wiring component is located closer to the vehicle door panel side than the planar member side mounting portion. Thus, before and after passing through the through portion, the arrangement order of the wiring component and the planar member side mounting portion opposite to the vehicle door panel is changed.

[0035] (7)In any one of the wiring modules of (2) to (6), it is possible that in the vehicle, a weatherstrip crosses the surface of the base portion, and a flange is provided at a portion of the periphery of the base portion including the portion where the weatherstrip crosses. The flange makes the step between the surface of the base portion and the surface of the vehicle door panel gentle. Thus, it is difficult to generate a gap between the boundary between the vehicle door panel and the grommet and the weatherstrip.

[0036] (8)In any one of the wiring modules of (1) to (7), it is possible that the grommet side mounting portion and the planar member side mounting portion are mounted by fitting a rib portion formed on one of the grommet side mounting portion and the planar member side mounting portion into a groove formed on the other of the grommet side mounting portion and the planar member side mounting portion. Thus, the grommet side mounting portion and the planar member side mounting portion are simply mounted.

[0037] (9)In the wiring module of (8), it is possible that the grommet side mounting portion and the planar member side mounting portion are mounted by fitting a rib portion formed on the grommet side mounting portion into a groove formed on the planar member side mounting portion. Thus, the mounting state of the grommet side mounting portion and the planar member side mounting portion is stable.

[0038] (10)In any one of the wiring modules of (1) to (9), it is possible that the wiring component includes a plurality of electric wires, and the plurality of electric wires are arranged flatly in the section from the base portion to the planar member. Thus, in the section from the base portion to the planar member, the height dimension of the wiring module from the vehicle door panel is suppressed to be small.

[0039] [Details of the Embodiment of the Present Disclosure]

[0040] A specific example of the wiring module of the present disclosure will be described below with reference to the accompanying drawings. It should be noted that the present disclosure is not limited to these examples, but is represented by the claims and is intended to include all changes within the meaning and scope equivalent to the claims.

[0041] [Embodiment 1]

[0042] Hereinafter, the wiring module of Embodiment 1 will be described.

[0043] <Vehicle Door>

[0044] First, refer to Figure 1 and describe the vehicle door in the vehicle. Figure 1 FIG. is a schematic top view showing the wiring module 20 of Embodiment 1 and the door panel 12 to which the wiring module 20 is assembled.

[0045] The vehicle door 10 is formed as a flat shape as a whole and is provided in the vehicle so as to be able to open and close in a manner that separates the interior of the vehicle from the exterior of the vehicle. Hereinafter, the open state and the closed state of the vehicle door 10 in the vehicle are simply referred to as the open state and the closed state. It is assumed that the vehicle door 10 is a driver's side door, a front passenger side door, a rear seat door, etc. It should be noted that hereinafter, the vehicle door 10 is set as a side door for description. The vehicle door may also be a rear door or the like. Further, the vehicle door 10 is set as a hinge door for description. The vehicle door may also be a sliding door or the like. The vehicle door 10 includes a door panel 12 and a wiring module 20.

[0046] The door panel 12 includes an outer panel 13 and an inner panel 14. The outer panel 13 is provided in the part of the vehicle door 10 facing the outside of the vehicle and is a part that constitutes the appearance of the vehicle together with the vehicle body. The inner panel 14 is provided on the vehicle interior side of the outer panel 13. The inner panel 14 has an inner plate portion 15 and a side plate portion 16. The inner plate portion 15 is the part facing the vehicle interior side in the closed state. A space capable of accommodating a window or an electrical device or the like is provided between the inner plate portion 15 and the outer panel 13. For example, an opening is formed in the inner plate portion 15 so that the space can be accessed. The side plate portion 16 is a part extending from the edge portion of the inner plate portion 15 toward the outer panel 13. In particular, here, the side plate portion 16 extends from the edge portion of the inner plate portion 15 located on the front side of the vehicle (the side where the hinge exists in the hinge door). The side plate portion 16 divides the space capable of accommodating a window or an electrical device or the like.

[0047] The wiring module 20 is assembled to the vehicle door 10. The wiring module 20 includes a wiring component 22, a planar component 30, and a grommet 40.

[0048] The wiring component 22 is a component that supplies power to the devices assembled to the vehicle door 10 or transmits signals between the devices assembled to the vehicle door 10 and the devices assembled to the vehicle body. Here, the wiring component 22 includes a plurality of electric wires 24. The wiring component 22 may also include an optical fiber cable or the like. The path and connection objects of the wiring component 22 in the vehicle are not particularly limited, and paths and connection objects such as the following can be considered. That is, one end portion of the wiring component 22 is disposed on the vehicle body. A connector C1 is provided at one end portion of the wiring component 22. This connector C1 is connected to a vehicle body side connector provided on a vehicle body side wiring component extending from a battery, an electronic control unit, or the like. The other end portion of the wiring component 22 is disposed on the vehicle door 10. The other end portion of the wiring component 22 is connected to the devices assembled to the vehicle door 10. The wiring component 22 and the devices provided on the vehicle door 10 may also be connected by a connector, for example. In this case, a connector C2 can be provided at the other end portion of the wiring component 22.

[0049] The middle portion of the wiring component 22 is spanned between the vehicle body and the vehicle door 10. More specifically, the wiring component 22 extends from the through-hole provided in the vehicle body toward the other end portion and extends toward the side plate portion 16 in the door panel 12. After the wiring component 22 reaches the side plate portion 16, it extends along the door panel 12 from the side plate portion 16 toward the inner plate portion 15.

[0050] The section of the wiring component 22 from the through-hole provided in the vehicle body to the side plate portion 16 and extending along the side plate portion 16 is covered and protected by a grommet 40. Regarding the portion of the wiring component 22 where the grommet 40 is provided, the plurality of electric wires 24 extend integrally. The wiring component 22 toward the inner plate portion 15 extends from the grommet 40. The portion of the wiring component 22 extending from the grommet 40 is held by a planar member 30. On the inner plate portion 15, the plurality of electric wires 24 branch and extend to the positions of the connected devices. The planar member 30 holds the wiring component 22 in the branched path.

[0051] The planar member 30 is provided on the vehicle door 10 on the vehicle interior side of the door panel 12. The planar member 30 is a member that extends in a planar shape with respect to the door panel 12. For example, the planar member 30 is disposed in the vehicle door 10 between the door panel 12 and the design trim. The planar member 30 is, for example, a flat part that extends to the same extent as or larger than the opening formed in the inner plate portion 15. The planar member 30 is assembled to the door panel 12 so as to block the opening formed in the inner plate portion 15. The planar member 30 is assembled to the inner panel 14 by, for example, screw fastening, a locking structure, or the like. For example, if the portion of the peripheral edge of the planar member 30 that overlaps with the inner panel 14 is fixed to the inner panel 14 by screw fastening or the like, the gap between them can be blocked as much as possible.

[0052] The grommet 40 is a so-called non-through grommet. The grommet 40 is assembled with respect to the inner panel 14 in the door panel 12 in a manner that crosses a portion of the periphery. The grommet 40 is mounted on the side plate portion 16. The grommet 40 is mounted on the wiring component 22 at a portion closer to the vehicle body side than the portion held by the planar component 30. The grommet 40 includes a base portion 42. The base portion 42 is mounted on the side plate portion 16. The base portion 42 is fixed at a fixed position relative to the door panel 12. Here, the base portion 42 is fixed at a fixed position relative to the door panel 12 means that the base portion 42 is fixed at a predetermined position predetermined for each door panel 12. It should be noted that the predetermined position of the fixed base portion 42 in the door panel 12 can be appropriately set. For example, the predetermined position is a position where the base portion 42 is fixed by bolts. In the grommet 40, the protective tube portion 52 extends from the base portion 42 toward the vehicle body side. A vehicle body mounting portion 54 is provided at the front end of the protective tube portion 52. The vehicle body mounting portion 54 is fixed to the vehicle body.

[0053] Here, a part of the planar member 30 is mounted on the grommet 40. The grommet 40 is a molded product based on an elastic material such as an elastomer and is easily deformed. The planar member 30 is a molded product made of a resin or metal and has higher rigidity than the grommet 40. A part of the planar member 30 is mounted on a portion of the grommet 40 that is desired to have a fixed shape, and the deformation of the grommet 40 in this portion is restricted.

[0054] In addition to the above-mentioned devices to which the wiring member 22 is connected, the vehicle door 10 also has, for example, a weather strip WS and design decorations (not shown) incorporated therein.

[0055] The weather strip WS is assembled relative to the door panel 12 in a manner extending along the periphery. Figure 1 The weather strip WS shown is assembled with respect to the inner panel 14 so as to extend along the periphery and surround the door panel 12. The weather strip WS has a portion that crosses the surface of the grommet 40. Normally, the weather strip WS is in a state of being deformed in a state of being sandwiched and crushed by the vehicle body and the door panel 12 in the closed state. In the closed state, the grommet 40 supports the deformation of the portion of the weather strip WS that crosses the grommet 40.

[0056] The design decoration is provided in the portion of the door 10 facing the inner side of the vehicle interior and is a portion that constitutes the interior appearance of the vehicle. For example, the door handle and the operation part of the vehicle-mounted equipment are mounted on the design decoration. The portion of the wiring component 22 along the inner plate portion 15 and the planar component 30 are covered by the design decoration.

[0057] The following describes each part of the wiring module 20 in detail. Figure 1 In addition, refer to Figures 2 to 5 The wiring member 22 will be described in detail. Figure 2This is a perspective view showing the wiring module 20 according to the first embodiment. Figure 3 This is a front view showing the wiring module 20 according to the first embodiment. Figure 4 This is a rear view showing the wiring module 20 according to the first embodiment. Figure 5 It is along Figure 3 Cross-sectional view taken along line VV.

[0058] <Wiring components>

[0059] The wiring component 22 has a first section, a second section, a third section, and a fourth section. The first section is a section covered by the protective tube portion 52 of the grommet 40. The second section is a section covered by the base portion 42 of the grommet 40. The third section is a section where the path limiting portion 35 described later of the planar component 30 is configured. The fourth section is a section where the main board portion 32 described later of the planar component 30 is configured. Here, the first section to the fourth section are arranged in this order from one end on the vehicle body side toward the other end on the door 10 side. The first section is mainly a section that is built between the vehicle body and the door 10. The second section is mainly a section that extends along the side panel portion 16. The third section is mainly a section that bends and extends from the side panel portion 16 toward the inner panel portion 15. The fourth section is mainly a section that extends along the inner panel portion 15.

[0060] The cross-sectional shape of each section in the wiring component 22 may also be a shape corresponding to the position of the configuration. For example, the first section in the wiring component 22 bundles the plurality of wires 24 in a manner that the cross-sectional shape is as close to a circular shape as possible. Thus, the first section in the wiring component 22 that passes through the protective cylinder 52 easily follows the deformation of the protective cylinder 52. The second section to the fourth section in the wiring component 22 arrange the plurality of wires 24 in one direction (here, the vertical direction) to form a flat shape. Thus, in the second section to the fourth section of the wiring component 22 extending along the door panel 12, the height dimension from the door panel 12 is suppressed from becoming larger. However, the cross-sectional shape of the wiring component 22 in each section can be appropriately set. For example, the cross-sectional shape of the wiring component may also be arranged in multiple columns and sections in the second section and the third section, so that it is flatter than the first section and higher in height than the fourth section.

[0061] When the cross-sectional shapes of the wiring member 22 are different in adjacent sections, the cross-sectional shape of the wiring member 22 changes at or near the boundary of the adjacent sections. For example, at the boundary between the first section and the second section, the shape of the wiring member 22 changes between a shape in which the plurality of wires 24 are bundled in a circular shape and a shape in which the plurality of wires 24 are arranged in a row.

[0062] Then, except Figures 1 to 5 In addition, refer to Figures 6 to 10The planar member 30 and the grommet 40 will be described in detail. Figure 6 and Figure 7 are exploded perspective views of the planar member 30 and the grommet 40. Figure 6 and Figure 7 are perspective views observed from opposite orientations. Figure 8 is a sectional view taken along line VIII-VIII of Figure 4 . Figure 9 is Figure 8 an enlarged view of region A1 of Figure 10 is Figure 8 an enlarged view of region A2 of

[0063] <Planar member>

[0064] The planar member 30 extends along the inner panel portion 15 of the door panel 12. The planar member 30 blocks the opening of the inner panel 14 or holds the wiring member 22 in a predetermined path. The planar member 30 can also hold part or all of the devices assembled to the door 10. The planar member 30 includes a main board portion 32 and a planar member side mounting portion 34.

[0065] The main board portion 32 holds the fourth section of the wiring member 22 that extends along the inner panel portion 15 of the door panel 12. The main board portion 32 is a portion that extends in a plate shape to an extent capable of blocking the opening formed in the inner panel portion 15. For example, multiple locations on the peripheral edge of the main board portion 32 are assembled to the inner panel 14 by screw fastening, a locking structure, etc. Here, the wiring member 22 is disposed on the surface of the main board portion 32 facing the vehicle interior. The wiring member 22 can also be disposed on the surface of the main board portion 32 facing the vehicle exterior. The wiring member 22 can also be disposed on both the surface of the main board portion 32 facing the vehicle interior and the surface facing the vehicle exterior. Hereinafter, the surface of the main board portion 32 where the wiring member 22 is disposed is defined as the disposed surface 33. Here, the disposed surface 33 is flat. The disposed surface 33 can also be formed into a concave-convex shape. It can also be that the portion of the disposed surface 33 that covers the opening is more recessed toward the vehicle exterior and enters the opening than the portion that covers the periphery of the opening. It can also be that the portion of the disposed surface 33 along the path where the wiring member 22 is disposed is flat. There can also be a concave-convex shape in a part of the path along which the wiring member 22 is disposed. The wiring member 22 is maintained in a state of being disposed on the disposed surface 33 so as to extend along a predetermined path.

[0066] The planar component side mounting portion 34 is provided at a part of the periphery of the main board portion 32. Here, the planar component side mounting portion 34 is provided at the periphery of the main board portion 32 near the door hinge. The planar component side mounting portion 34 is mounted on the grommet 40. Here, the planar component side mounting portion 34 extends forward (towards the door hinge) and downward from the main board portion 32. The planar component side mounting portion 34 can also extend in any direction from the main board portion 32. Here, the planar component side mounting portion 34 has a path restricting portion 35 and a mounting body 38. The planar component side mounting portion 34 is formed in a flat plate shape. The portion of the planar component side mounting portion 34 from the base end portion on the main board portion 32 side to the middle portion in the length direction is set as the path restricting portion 35. The portion of the planar component side mounting portion 34 closer to the front end side than the path restricting portion 35 is set as the mounting body 38.

[0067] The path restricting portion 35 restricts the path of the wiring component 22. Here, a bending portion 36 is provided at the middle portion in the length direction of the path restricting portion 35. The portion of the path restricting portion 35 from the base end portion on the main board portion 32 side to the bending portion 36 extends along the inner panel portion 15. The portion of the path restricting portion 35 from the bending portion 36 to the front end portion extends along the side panel portion 16. Thus, the path restricting portion 35 restricts the state of bending and extending between the side panel portion 16 and the inner panel portion 15 in the wiring component 22. And, here, a through portion 37 is provided at the middle portion in the length direction of the path restricting portion 35.

[0068] The through portion 37 is a portion through which the wiring component 22 passes. The wiring component 22 passes through the through portion 37 and transfers from one surface side of the path restricting portion 35 to the other surface side. The wiring component 22 passes through the vehicle interior side relative to the path restricting portion 35 at a position closer to the base end side of the path restricting portion 35 than the through portion 37. The wiring component 22 passes through the vehicle exterior side relative to the path restricting portion 35 at a position closer to the front end side of the path restricting portion 35 than the through portion 37. The path restricting portion 35 is located between the wiring component 22 and the door panel 12 at a position closer to the base end side of the path restricting portion 35 than the through portion 37. The wiring component 22 is disposed between the path restricting portion 35 and the door panel 12 at a position closer to the front end side of the path restricting portion 35 than the through portion 37. Here, a through hole is formed in the path restricting portion 35 and set as the through portion 37. However, as the through portion 37, it is not necessary to form a through hole. For example, it may be that the side edge of the path restricting portion 35 is recessed to be the through portion.

[0069] The position of the through portion 37 along the length direction of the path restricting portion 35 can be any position. Here, the through portion 37 is provided at the position of the bending portion 36 along the length direction of the path restricting portion 35. Thus, it is no longer necessary to provide both the bending when the wiring component 22 passes through the through portion 37 and the bending in the bending portion 36. As Figure 5As shown, the wiring component 22 extends straight from the mounting body 38 side to pass through the insertion portion 37 at the front end of the path restricting portion 35, and bends along the bending portion 36 after passing through the insertion portion 37.

[0070] The middle portion in the width direction of the path restricting portion 35 is a thin wall and is formed in a groove shape. The wiring component 22 is arranged in the groove portion 35a. In the path restricting portion 35, the surface for arranging the wiring component 22 changes with the insertion portion 37 as the boundary. Therefore, in the path restricting portion 35, the surface forming the groove portion 35a changes with the insertion portion 37 as the boundary. The groove portion 35a is formed on the surface facing the door panel 12 side at the front end side relative to the insertion portion 37, and is formed on the surface facing the vehicle interior side at the base end side relative to the insertion portion 37. The wall thickness at the groove portion 35a in the path restricting portion 35 is, for example, about half of the wall thickness of the portion near the groove portion 35a along the width direction of the path restricting portion 35. The width dimension of the groove portion 35a in the path restricting portion 35 is, for example, about half of the width dimension of the path restricting portion 35. The groove portion 35a is continuous to the mounting body 38 at the front end side relative to the insertion portion 37, but does not reach the front edge portion of the surface component side mounting portion 34. And the front end portion of the groove portion 35a is formed in a gentle inclined surface shape along its length direction.

[0071] Both side edges of the path restricting portion 35 are thick walls and are formed in rib shapes. The rib portion 35b is continuous from the base end portion of the path restricting portion 35 to the front end side relative to the insertion portion 37. By providing the rib portion 35b, the rigidity of the path restricting portion 35 is improved. The rib portion 35b suppresses the decrease in the rigidity of the path restricting portion 35 caused by the provision of the insertion portion 37.

[0072] The planar shape of the mounting body 38 is a shape corresponding to the shape of the portion surrounded by the rib 49. Here, the planar shape of the mounting body 38 is formed in a concave shape with a middle portion of one edge of a quadrilateral shape recessed. The through hole 44 is located at the concave portion of the mounting body 38. The mounting body 38 overlaps the substrate portion 43 of the base portion 42 in such a way as not to block the through hole 44. Grooves 39 are formed on the outer peripheral surface of the mounting body 38.

[0073] The grooves 39 are formed in a series along the outer peripheral surface of the mounting body 38. The grooves 39 are formed at the position of the middle portion in the thickness direction of the outer peripheral surface of the mounting body 38. For example, the width dimension of the grooves 39 is about half of the thickness dimension of the mounting body 38. For example, the depth dimension of the grooves 39 is the same as the protruding dimension of the rib portion 50 from the rib 49.

[0075] The cable gland 40 includes a door mounting portion 41, a protection cylinder portion 52, and a vehicle body mounting portion 54.

[0076] The door mounting portion 41 is the portion mounted on the door panel 12. The door mounting portion 41 is mounted on the side plate portion 16. The door mounting portion 41 includes a base portion 42 and a grommet side mounting portion 48.

[0077] The base portion 42 is formed flat. The base portion 42 is mounted in a manner that extends on the surface of the side plate portion 16. The base portion 42 has a substrate portion 43 and a flange 47.

[0078] The substrate portion 43 is formed in a flat plate shape. In Figure 3 In the example shown, the substrate portion 43 is pentagonal in shape, but it can also be other shapes. One surface of the substrate portion 43 faces the vehicle body side, and the other surface faces the door panel 12 side. A protective cylinder portion 52 is provided on one surface of the substrate portion 43. A through hole 44 is formed in the portion of the substrate portion 43 where the protective cylinder portion 52 is provided.

[0079] The through hole 44 communicates with the protective cylinder portion 52. The wiring member 22 passes from the other end side toward the one end side, passes through the other surface side of the substrate portion 43 and through the through hole 44, and is guided into the interior of the protective cylinder portion 52. In the substrate portion 43, an annular protrusion 45 is formed on the periphery of the through hole 44.

[0080] The annular protrusion 45 is formed in such a manner that the peripheral portion of the through hole 44 in the substrate portion 43 protrudes toward the other surface side. The annular protrusion 45 is formed to have the same wall thickness as other portions in the substrate portion 43. On one surface side of the substrate portion 43, the portion where the annular protrusion 45 is formed is recessed toward the other surface side compared with its surrounding portions. On the other surface side of the substrate portion 43, the portion where the annular protrusion 45 is formed protrudes toward the door panel 12 side compared with its surrounding portions. The protruding dimension of the annular protrusion 45 is of the same degree as the protruding dimension of the rib 49. By providing the annular protrusion 45, the wiring member 22 is prevented from strongly colliding with the rib 49 at the portion guided from the side plate portion 16 to the protective cylinder portion 52.

[0081] Mounting holes 46 are formed in the base portion 42. Bolts, clips, etc. pass through the mounting holes 46. By fastening or clamping the bolts, clips, etc. passing through the mounting holes 46 to the door panel 12, the base portion 42 is assembled to the door panel 12. Here, two mounting holes 46 are formed in the substrate portion 43. The two mounting holes 46 are separately provided in the vertical direction above and below with respect to the wiring member 22. The two mounting holes 46 are formed so as to be on the same side (here, the outer side along the vehicle's inside-outside direction) with respect to the weatherstrip WS.

[0082] The flange 47 is formed at the outer edge portion of the substrate portion 43. More specifically, as Figure 4As shown, the flange 47 is formed to project outward from the other edge portions of the substrate portion 43 except for one edge portion 43a. This edge portion 43a is located on the vehicle interior side of the substrate portion 43 and extends in the vertical direction. The flange 47 is formed with a thin wall compared to the substrate portion 43. The flange 47 is provided on one surface side of the substrate portion 43. The flange 47 projects obliquely toward the door panel 12 side. The flange 47 projects toward the door panel 12 side compared to the annular projecting portion 45 and the rib 49 in the base portion 42. In a state where the grommet 40 is assembled to the door panel 12, the flange 47 elastically deforms along the door panel 12 and closely adheres to the door panel 12.

[0083] The flange 47 is also provided at a portion where the weatherstrip WS in the grommet 40 crosses. By providing the flange 47 at the portion where the weatherstrip WS in the grommet 40 crosses, as Figure 9 shown, the step between the door panel 12 and the grommet 40 becomes smaller. Thereby, it is difficult to generate a gap in the portion surrounded by the weatherstrip WS, the door panel 12, and the grommet 40. Here, the weatherstrip WS crosses on one surface of the substrate portion 43 on the vehicle interior side of the portion where the through hole 44 is formed.

[0084] The grommet side mounting portion 48 is connected to the base portion 42. A planar member side mounting portion 34 is mounted on the grommet side mounting portion 48. Here, the grommet side mounting portion 48 is provided on the other surface of the substrate portion 43. The grommet side mounting portion 48 has a rib 49 and a ribbed portion 50.

[0085] The rib 49 is provided on the other surface of the substrate portion 43. The rib 49 projects from the substrate portion 43 toward the door panel 12 side. The height dimension of the rib 49 from the substrate portion 43 is about the same as the wall thickness of the mounting body 38. In the substrate portion 43, the rib 49 is provided to extend along the following path. That is, the rib 49 starts from a part of the edge portion 43a in the substrate portion 43, extends in an M shape on the substrate portion 43, and reaches another part of the edge portion 43a in the substrate portion 43. The middle portion of the rib 49 extends along the annular projecting portion 45 on the edge portion 43a side of the annular projecting portion 45. The through hole 44 and the annular projecting portion 45 are not included in the portion surrounded by the rib 49. Also, the mounting hole 46 is not included in the portion surrounded by the rib 49.

[0086] The ribbed portion 50 is provided on the inner peripheral surface of the rib 49. The ribbed portion 50 is provided over the entire length of the rib 49. The ribbed portion 50 projects parallel to the substrate portion 43 starting from a position in the middle portion along the height direction of the rib 49. As Figure 10 shown, the ribbed portion 50 is inserted into the groove 39 of the mounting body 38.

[0087] The protective cylinder part 52 is provided to protrude from one surface of the base part 42. The protective cylinder part 52 communicates with the through-hole 44. The protective cylinder part 52 is formed to have flexibility. The structure for the protective cylinder part 52 to have flexibility can be any structure. Here, the protective cylinder part 52 is formed in a corrugated shape and has flexibility.

[0088] The vehicle body mounting part 54 is provided at the other end of the protective cylinder part 52. Here, the vehicle body mounting part 54 is provided so as to be able to be engaged with the through-hole formed in the vehicle body.

[0089] As Figure 5 shown, the mounting body 38 of the planar member 30 is sandwiched at a position on the door panel 12 side of the grommet 40 that is closer to the door panel 12 than the portion where the weatherstrip WS passes through. The mounting body 38 is located on the weatherstrip WS side of the wiring member 22. The mounting body 38 supports the deformation of the weatherstrip WS in the closed state.

[0090] <Mounting of the planar member and the grommet>

[0091] Here, after the planar member 30 and the grommet 40 are separately formed, they can be assembled by mounting the planar member side mounting part 34 and the grommet side mounting part 48. For example, the front end part of the mounting body 38 of the planar member side mounting part 34 is inserted between the ribs 49 of the grommet side mounting part 48 from the edge part 43a side to mount the planar member side mounting part 34 and the grommet side mounting part 48. At this time, first, two parts of the ridge part 50 of the rib 49 that extend separately in the vertical direction from the edge part 43a are inserted into the corresponding parts of the groove 39 of the mounting body 38 (the part formed on the upper surface of the upper edge part and the part formed on the upper surface of the upper edge part). When the mounting body 38 is directly inserted into the grommet side mounting part 48 in this way, the part of the ridge part 50 of the rib 49 that bends so as to avoid the through-hole 44 and extends in the vertical direction is also inserted into the corresponding part of the groove 39. Thus, the planar member side mounting part 34 and the grommet side mounting part 48 are mounted by all of the ridge part 50 of the rib 49 being inserted into the groove 39. Thereby, a state in which the planar member 30 and the grommet 40 are mounted is formed. In the mounted state of the planar member side mounting part 34 and the grommet side mounting part 48, when the grommet side mounting part 48 is elastically deformed in a slightly expanded manner due to the planar member side mounting part 34, a state is formed in which the grommet side mounting part 48 fastens the planar member side mounting part 34 by its restoring force, and the planar member side mounting part 34 and the grommet side mounting part 48 are difficult to come off and difficult to loosen.

[0092] <Effects of Embodiment 1, etc.>

[0093] According to the wiring module 20 configured as described above, by installing the planar member 30 and the grommet 40, when one of the planar member 30 and the grommet 40 is positioned on the door panel 12, the other can also be positioned on the door panel 12. Thus, in the wiring module 20 provided with both the grommet 40 and the planar member 30 on the wiring member 22, the assemblability to the door panel 12 can be improved. Moreover, in the wiring module 20, most of the portion of the wiring member 22 extending along the door panel 12 is maintained in a state of extending along a predetermined path by the planar member 30 and the grommet 40. Therefore, when one of the planar member 30 and the grommet 40 is positioned on the door panel 12, most of the portion of the wiring member 22 extending along the door panel 12 is positioned on a predetermined path opposite to the door panel 12.

[0094] Moreover, the grommet 40 is assembled on the surface of the door panel 12, and the base portion 42 is fixed to the surface of the side plate portion 16 of the door panel 12. Thus, the grommet 40 is a non-through grommet, so that the wiring module 20 can be simply assembled on the door panel 12.

[0095] Moreover, the main board portion 32 and the planar member side mounting portion 34 are assembled on the surface of the door panel 12. Thus, in addition to the grommet 40, the planar member 30 is also a member assembled on the surface of the door panel 12. Thus, when assembling the wiring module 20 on the door panel 12, it can be assembled without performing the operation of passing the wiring member 22 through the door panel 12.

[0096] Moreover, the planar member side mounting portion 34 extends from the inner plate portion 15 to the side plate portion 16 of the door panel 12, and the grommet side mounting portion 48 is provided on the surface of the base portion 42 facing the side plate portion 16. Thus, the portion of the wiring member 22 extending between the inner plate portion 15 and the side plate portion 16 is guided by the planar member side mounting portion 34.

[0097] Moreover, in the vehicle, the weatherstrip WS crosses the surface of the base portion 42, and the planar member side mounting portion 34 extends to the portion of the base portion 42 overlapping the weatherstrip WS. Thus, the planar member side mounting portion 34 can support the portion of the base portion 42 overlapping the weatherstrip WS, and the flattening mode of the weatherstrip WS in the closed state is stable.

[0098] An insertion portion 37 through which the wiring component 22 passes is formed in the planar component side mounting portion 34. Near the wiring component 22 on the main board portion 32 side with respect to the insertion portion 37, the planar component side mounting portion 34 is located closer to the door panel 12 than the wiring component 22. Near the wiring component 22 on the vehicle body side with respect to the insertion portion 37, the wiring component 22 is located closer to the door panel 12 than the planar component side mounting portion 34. Thus, before and after passing through the insertion portion 37, the arrangement order of the wiring component 22 and the planar component side mounting portion 34 opposite to the door panel 12 is changed.

[0099] The insertion portion 37 is provided closer to the main board portion 32 than the portion where the weatherstrip WS crosses. Thus, at the portion where the weatherstrip WS crosses, it is possible to prevent the wiring component 22 from being pinched by the grommet 40 and the planar component side mounting portion 34. Thus, flattening of the wiring component 22 is suppressed. Also, interference of the wiring component 22 with the flattening of the weatherstrip WS in the closed state is suppressed, and the flattening mode of the weatherstrip WS is stable. The insertion portion 37 is provided at the boundary between the side plate portion 16 and the inner plate portion 15. The boundary between the side plate portion 16 and the inner plate portion 15 is the portion where the wiring component 22 bends. By providing the insertion portion 37 at the boundary between the side plate portion 16 and the inner plate portion 15, it is not necessary to bend the wiring component 22 additionally to pass through the insertion portion 37.

[0100] Also, the flange 47 makes the step between the surface of the base portion 42 and the surface of the door panel 12 gentle. Thus, it is difficult to generate a gap between the boundary between the door panel 12 and the grommet 40 and the weatherstrip WS.

[0101] Also, the grommet side mounting portion 48 and the planar component side mounting portion 34 are mounted by fitting a rib portion 50 formed on the grommet side mounting portion 48 into a groove 39 formed on the planar component side mounting portion 34. Thus, the grommet side mounting portion 48 and the planar component side mounting portion 34 are simply mounted. Moreover, the mounting state of the grommet side mounting portion 48 and the planar component side mounting portion 34 is stable.

[0102] Also, a plurality of electric wires 24 are arranged flatly in the section from the base portion 42 to the planar component 30 (the second section to the fourth section). Thus, in the section from the base portion 42 to the planar component 30, the height dimension of the wiring module 20 from the door panel 12 is suppressed to be small.

[0103] [Modification Example]

[0104] So far, it has been described that both the planar component 30 and the grommet 40 are non-through type, but this is not an essential structure. It may also be that either one or both of the planar component and the grommet are of the type that penetrates the door panel 12.

[0105] And so far, it has been described that the portion of the wiring member 22 that bends from the side plate portion 16 toward the inner plate portion 15 is held by the planar member 30, but this is not a necessary structure. The portion of the wiring member 22 that bends from the side plate portion 16 toward the inner plate portion 15 may also be held by a grommet. In this case, a protective portion protruding from the base portion 42 toward the planar member may be provided on the grommet. The protective portion may also be in a shape such as a cylindrical shape or a plate shape. The planar member may also omit the path restricting portion 35 and be formed in a shape in which the mounting body 38 protrudes directly from the main board portion 32. Further, the grommet-side mounting portion and the planar-member-side mounting portion provided on the protective portion may be mounted.

[0106] And so far, it has been described that the planar-member-side mounting portion 34 extends to the portion of the base portion 42 that overlaps with the weatherstrip WS, but this is not a necessary structure. The planar-member-side mounting portion 34 may not extend to the portion of the base portion 42 that overlaps with the weatherstrip WS.

[0107] And so far, it has been described that the grommet-side mounting portion 48 and the planar-member-side mounting portion 34 are mounted by fitting the rib portion 50 formed on the grommet-side mounting portion 48 into the groove 39 formed on the planar-member-side mounting portion 34, but this is not a necessary structure. The grommet-side mounting portion and the planar-member-side mounting portion may also be mounted by fitting a rib portion formed on the planar-member-side mounting portion into a groove formed on the grommet-side mounting portion.

[0108] It should be noted that the structures described in the above-described embodiments and each modification can be appropriately combined as long as they do not conflict with each other.
