[0027] [Description of Embodiments of the Present Disclosure]

[0028] First, embodiments of the present disclosure will be described by way of examples.

[0029] The wiring module for a vehicle door of the present disclosure is as follows.

[0030] (1) A wiring module for a vehicle door, comprising: an inspection hole cover having a groove formed on a main surface; a wiring member received in the groove; and a wiring cover fixed to the inspection hole cover and closing the opening of the groove, wherein a first mounting portion and a second mounting portion are provided on both sides of the main surface of the inspection hole cover sandwiching the groove, a first end portion of the wiring cover being mounted on the first mounting portion, and a second end portion of the wiring cover being mounted on the second mounting portion, wherein the inspection hole cover and the wiring cover are arranged so that, in a temporary installation state in which the first end portion is mounted on the first mounting portion and the second end portion is not mounted on the second mounting portion, the wiring member can be free with a space between the second end portion and the second mounting portion. The wiring cover and the inspection hole cover are arranged so that, in a temporary installation state in which the first end portion is mounted on the first mounting portion and the second end portion is not mounted on the second mounting portion, the wiring member can be free with a space between the second end portion and the second mounting portion. Thus, in the temporary installation state, the wiring member can be easily received in the groove through the space between the second end portion and the second mounting portion. Furthermore, by attaching the first end portion to the first mounting portion, the wiring member is less likely to fall out of the groove between the time the wiring member is received in the groove and the time the second end portion is attached to the second mounting portion.

[0031] (2) In the vehicle door wiring module of (1), in the temporarily mounted state, the first mounting portion may support the first end portion in a position enabling the second end portion to extend toward a free position above the second mounting portion, and the wiring cover supported in a cantilevered manner on the manhole cover may have rigidity sufficient to maintain the second end portion free above the second mounting portion. Thus, the structures of the first mounting portion, the second mounting portion, and the wiring cover may be simplified.

[0032] (3) In the door wiring module of (2), the mounting surface of the second mounting portion may be located closer to the bottom of the groove along the height direction of the groove than an imaginary plane formed by extending the mounting surface of the first mounting portion. Thus, when the flat wiring cover is supported in a cantilevered manner on the manhole cover, the second end portion can be freed upward from the second mounting portion.

[0033] (4) In the door wiring module of (2) or (3), the mounting surface of the first mounting portion may be an inclined surface whose height from the bottom of the groove decreases as the distance from the first mounting portion increases. This facilitates increasing the space between the second end of the wiring cover and the second mounting portion when the second end of the wiring cover is in the free position.

[0034] (5) In the door wiring module of (4), the mounting surface of the second mounting portion may be an inclined surface whose height from the bottom of the groove increases as the distance from the groove increases. This reduces the stress concentration on the wiring cover when the second end of the wiring cover is mounted on the second mounting portion.

[0035] (6) In any of the door wiring modules of (1) to (5), the portion of the bottom of the groove on the first mounting portion side along the width direction of the groove may be an inclined surface whose depth increases toward the first mounting portion. This can prevent the wiring member housed in the groove from being caught between the first end portion of the wiring cover and the first mounting portion.

[0036] (7) In any of the door wiring modules of (1) to (6), the wiring covers may be provided at a first location and a second location spaced apart along the longitudinal direction of the groove, respectively, and the second end portion of the wiring cover at the first location and the second end portion of the wiring cover at the second location may be provided on the same side relative to the groove. Thus, when the wiring member is accommodated in the groove through the space between the second end portion and the second mounting portion, the wiring member can be accommodated in the groove from the same side at the first location and the second location, and the wiring member can be easily accommodated in the groove.

[0037] (8) In any of the door wiring modules of (1) to (6), the wiring cover may be provided at a first portion and a second portion spaced apart along the longitudinal direction of the groove, respectively, and the second end portion of the wiring cover at the first portion and the second end portion of the wiring cover at the second portion may be provided on opposite sides of the groove. Thus, when the second end portion of the wiring cover is attached to the second mounting portion after accommodating the wiring member, the wiring member is unlikely to fall out of the groove because the first portion and the second portion are closed on opposite sides of the groove.

[0038] (9) In any one of the wiring modules for vehicle doors of (1) to (8), the plurality of wiring members may be housed in the groove in a mutually free state. Thus, by housing the plurality of wiring members in a mutually free state in the groove, the wiring members can be brought into a converged state.

[0039] (10) In addition, the composite manhole cover disclosed in the present invention comprises: a manhole cover having a groove formed on one main surface; and a wiring cover having a first end and a second end, wherein a first mounting portion and a second mounting portion are provided on both sides of the groove in the one main surface of the manhole cover, wherein the first end is mounted on the first mounting portion, the middle portion between the first end and the second end covers the opening of the groove, and the second end has a space between the second mounting portion and the second end. In the wiring cover, the first end is mounted on the first mounting portion, the middle portion between the first end and the second end covers the opening of the groove, and the second end has a space between the second mounting portion and the second end. Thus, the wiring component can be easily accommodated in the groove through the space between the second end of the wiring cover and the second mounting portion. Moreover, by mounting the first end of the wiring cover on the first mounting portion, the wiring component is unlikely to fall out of the groove during the period from the accommodation of the wiring component to the mounting of the second end of the wiring cover on the second mounting portion. As described above, a wiring component retaining structure based on the groove and the wiring cover can be easily formed.

[0040] [Details of the embodiments of the present disclosure]

[0041] Specific examples of the vehicle door wiring module of the present disclosure are described below with reference to the accompanying drawings. It should be noted that the present disclosure is not limited to these examples but is indicated by the scope of the claims and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.

[0042] [Implementation Method 1]

[0043] Hereinafter, the door wiring module according to the first embodiment will be described. Figure 1 1 is a plan view showing the door wiring module 30 and the door panel 20 to which the door wiring module 30 is attached according to the first embodiment. Figure 2 yes Figure 1 Cross-sectional view along line II-II.

[0044] First, let's briefly describe the vehicle door 10. The door 10 is generally flat and is an openable and closable portion of the vehicle, separating the interior from the exterior. The door 10 can be a driver's door, a passenger door, or a rear seat door. The door 10 includes a door panel 20, exterior trim, and a door wiring module 30.

[0045] The door panel 20 includes an outer panel 21 and an inner panel 22. The outer panel 21 is a portion of the vehicle door 10 that faces the outside of the vehicle and, together with the vehicle body, constitutes the exterior appearance of the vehicle. The inner panel 22 is provided on the vehicle interior side of the outer panel 21. The inner panel 22 includes 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 inside of the vehicle interior. The main panel portion 25 is connected 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. Door equipment provided in the vehicle door 10 is arranged in this space, or window glass is accommodated. An inspection hole 26 is provided in the main panel portion 25 of the inner panel 22. An operator can access the space between the outer panel 21 and the inner panel 22 through the inspection hole 26 from the outside of the inner panel 22.

[0046] The exterior trim is the portion of the vehicle door 10 that faces the interior and contributes to the vehicle's interior appearance. For example, interior handles and operating components for onboard equipment are mounted on the exterior trim. The portion of the door wiring module 30 that is assembled to the vehicle door 10 is located between the exterior trim and the outer panel 21.

[0047] The door wiring module 30 includes a manhole cover 40 , a wiring member 50 , and a wiring cover 60 .

[0048] The manhole cover 40 covers the manhole 26. The manhole cover 40 is a flat resin component that extends to the same extent as or greater than the manhole 26. The manhole cover 40 is installed to close the manhole 26. When the manhole cover 40 is attached to the manhole 26 in the inner panel 22, this attachment is maintained by screw fastening, a locking mechanism, or adhesive bonding. For example, by bonding the portion of the perimeter of the manhole cover 40 that overlaps the inner panel 22 to the inner panel 22, the gap between them can be closed as much as possible.

[0049] The manhole cover 40 separates the inner side of the vehicle interior from the space between the outer panel 21 and the inner panel 22. Window glass exposed to rainwater is housed in this space, and a slit-shaped opening is formed above this space for the window glass to enter and exit. Therefore, this space is a space where water may enter. Moreover, this space is a space where there is a possibility of connection with the outside space, and therefore, it is also a space where wind noise from the outside may invade. Therefore, the manhole cover 40 can be provided as a component that, together with the inner panel 22, more completely separates the vehicle interior space from the outside space. More specifically, the manhole cover 40 includes a cover body 41, a frame 42, and a flange 43. For example, the manhole cover 40 is a component formed by mold-molding a resin such as polypropylene (PP), and has rigidity that is difficult to bend.

[0050] The cover body 41 is a plate-shaped extension slightly smaller than the manhole 26. A frame 42 protrudes from the outer edge of the cover body 41 toward one of its main surfaces 41a (the inner side of the vehicle interior). A flange 43 protrudes from the outer edge of the frame 42 toward the outer periphery. The frame 42 can be formed as an inclined surface with a height gradually decreasing from the flange 43 toward the cover body 41. When the manhole cover 40 is installed at a predetermined position on the manhole 26 of the inner panel 22, the cover body 41 is positioned inside the manhole 26 (towards the outer panel 21 relative to the main panel 25), while the flange 43 is positioned outside the manhole 26 (towards the inner side of the vehicle interior relative to the main panel 25), with the frame 42 connecting the two. Consequently, the frame 42 and flange 43 seal the gap between the opening edge of the cover body 41 and the periphery of the manhole 26.

[0051] A groove 44 is formed on the main surface of the manhole cover 40 (main surface 41a of the cover body 41). Here, the groove 44 is formed on the main surface 41a of the manhole cover 40 that faces the inner side of the vehicle interior. The groove 44 may also be formed on the main surface 41b of the manhole cover 40 that faces the outer side of the vehicle interior. The groove 44 may also be formed on both main surfaces 41a and 41b.

[0052] The groove 44 is formed to a size that can accommodate multiple wiring members 50. The groove 44 is formed flatly, and the width dimension is larger than the depth dimension. The depth dimension of the groove 44 can be larger than the diameter of the wiring member 50 (in the case where the multiple wiring members 50 include wiring members of different thicknesses, it is the diameter of the largest wiring member 50). In order to be able to stack the wiring members 50 in two or more sections and accommodate them, the depth dimension of the groove 44 can be larger than twice the diameter of the wiring member 50 (in the case where the multiple wiring members 50 include wiring members of different thicknesses, it is the diameter of the smallest wiring member 50). A plurality of grooves of a size that can separately accommodate multiple wiring members 50 can be formed in multiple rows as the groove 44. For example, grooves of a size that can accommodate the wiring members 50 one by one can be formed in multiple rows.

[0053] The opening of the slot 44 is covered by a wiring cover 60. The manhole cover 40 is provided with a first mounting portion 45 and a second mounting portion 46 for mounting the wiring cover 60. The first mounting portion 45 and the second mounting portion 46 are provided separately on either side of the main surface 41a, sandwiching the slot 44. Details of the first mounting portion 45 and the second mounting portion 46 will be described later.

[0054] On the main surface 41b opposite the main surface 41a where the groove 44 is formed, the portion opposite the groove 44 is formed as a ridge 47. This prevents the thickness of the portion where the groove 44 is formed from decreasing. However, the portion opposite the groove 44 on the main surface 41b does not need to be formed as a ridge 47. The portion opposite the groove 44 on the main surface 41b and the surrounding portion may be flat.

[0055] The manhole cover 40 has an insertion hole 48 formed therein for the wiring member 50 to pass through. The wiring member 50 passes through the insertion hole 48 and extends through the manhole cover 40. The insertion hole 48 can be formed in the cover body 41 or the frame 42 of the manhole cover 40. Here, the insertion hole 48 is formed in the frame 42. In particular, the insertion hole 48 is formed at the end of the groove 44 in the frame 42. Thus, the wiring member 50 accommodated in the groove 44 can pass through the insertion hole 48 and extend through the manhole cover 40.

[0056] The wiring component 50 connects the door device to the body device provided on the vehicle body and supplies power to the door device, or transmits signals between the door device and the body device. The wiring component 50 may include an electric wire 52. As the electric wire 52, a coated electric wire having a coating formed around a core wire composed of a conductor may be used. The core wire may be a single core wire or a twisted wire. The type of the electric wire 52 is not particularly limited, and may include a single wire, a composite wire, etc. A single wire is an electric wire having one conductive path. A composite wire is an electric wire having multiple conductive paths. As a composite wire, it may be a composite wire formed by combining multiple single wires, such as a twisted wire or a composite cable. The wiring component 50 may include an optical fiber cable, etc. The number of wiring components 50 is set according to the number of door devices, etc. Usually, a plurality of wiring components 50 are provided.

[0057] The paths of the plurality of wiring members 50 are appropriately set according to the specifications of the vehicle door 10. For example, in the case of a typical hinged vehicle door whose rotation axis extends along the height direction of the vehicle, the plurality of wiring members 50 assembled in the hinged vehicle door are generally connected to the vehicle body near the door hinge, and branch from the door hinge side toward the side opposite the door hinge to be connected to various door devices.

[0058] More specifically, it is conceivable that one end portion of the plurality of wiring members 50 is bundled and passed through a portion of the vehicle door 10 (at Figure 1In the example shown, the side panel portion 23 on the door hinge side extends from the door 10, is guided into the vehicle body, and is connected to the vehicle body equipment via a common connector C1 or the like, or is connected to a relay connector provided at the end of a wiring member extending from the vehicle body equipment. The above-mentioned vehicle body equipment is not particularly limited, and examples thereof include an electronic control unit (ECU) or a battery. Grommets G are usually installed on the portion of the wiring members 50 that extends between the door 10 and the vehicle body. Figure 1 In the example shown, the grommet G is a so-called through-type grommet that is inserted and locked into a through hole formed in the side plate portion 23. This can prevent water from entering through the through hole. The grommet G may also be a so-called non-through-type grommet that fits into a recess formed in the edge portion where the side plate portion 23 and the main plate portion 25 intersect. A plurality of wiring components 50 extend from the grommet G midway from one end toward the other end, branch out, and extend toward the door devices that become the respective connection destinations. Connectors C2 and C3 corresponding to the door devices that become the connection destinations are installed at the other ends of the plurality of wiring components 50. Each connector C2 and C3 is connected to, for example, connectors C4 and C5 on the door device side. In Figure 1 and Figure 2 , two door device-side connectors C4 and C5, and wires 52A and 52B connected to connectors C4 and C5 via connectors C2 and C3 are shown. Connector C4 is, for example, a connector for an actuator for locking and unlocking door 10. Connector C5 is, for example, a connector for a footlight.

[0059] exist Figure 1 and Figure 2 In the embodiment, description of connectors and wiring components other than the connectors C1-C3 and the wires 52A and 52B connected thereto is omitted in the door wiring module 30. Of course, the door wiring module 30 may include connectors other than the connectors C1-C3 and wiring components other than the wires 52A and 52B.

[0060] The electric wires 52A and 52B pass through the insertion hole 48 and penetrate the manhole cover 40 halfway from the portion provided with the grommet G toward the connectors C2 and C3, and are moved toward the vehicle interior side of the manhole cover 40. The electric wires 52A and 52B can pass through holes other than the manhole 26 in the inner panel 22 halfway from the portion provided with the grommet G toward the connectors C2 and C3, and are moved toward the vehicle interior side of the inner panel 22.

[0061] The section of the electric wire 52 extending between the grommet G and the manhole cover 40 may be a bundled portion bundled by a bundling member. Figure 1In the example shown, the adhesive tape T is wound in a spiral shape to bundle the plurality of electric wires 52. The bundling member may be a bundling tape, a flexible sheet, a corrugated tube, etc. The bundling member can bundle the plurality of electric wires 52 in a bendable manner.

[0062] The section of the wire 52 extending along the manhole cover 40 is located inside the vehicle interior relative to the manhole cover 40. Furthermore, the section of the wire 52 extending along the manhole cover 40 is restricted in its path by the manhole cover 40. Restricting the path of the wire 52 means that the path of the wire 52 is maintained at a predetermined path.

[0063] The section of the electric wire 52 that extends along the manhole cover 40 is accommodated in the groove 44. The groove 44 is formed along the path of the electric wire 52 relative to the manhole cover 40. Here, three grooves 44A, 44B, and 44C are formed as the grooves 44. The groove 44A is formed along the front-to-back direction of the vehicle from the front to the rear of the manhole cover 40. When the manhole cover 40 is viewed from the vehicle cabin side, the groove 44A is formed in a straight line extending in the front-to-back direction of the vehicle. The grooves 44B and 44C branch from the ends of the groove 44A. The groove 44B is formed in a straight line extending in the front-to-back direction of the vehicle. The groove 44C is formed in a straight line extending in the height direction of the vehicle. It is not necessary for each groove 44 to extend in a straight line on the main surface 41a of the cover body, and it can also extend in a curved manner on the main surface 41a of the cover body.

[0064] The branching portion of the wires 52A and 52B on the manhole cover 40 branches from a main line into two branch lines. The main line is the portion where the wires 52A and 52B run parallel to each other. The two branch lines are portions where the wires 52A and 52B extend independently. The main line is housed in the groove 44A, and the two branch lines are housed in the grooves 44B and 44C, respectively. The grooves 44A and 44B can be used to hold the wire 52A connected to door equipment installed at the rear of the vehicle door 10, such as the door locking and unlocking actuator. The grooves 44A and 44C can be used to hold the wire 52B connected to door equipment installed at the bottom of the vehicle door 10, such as the footlights. The size of each groove 44 in the cross-sectional view can be formed to correspond to the size of the wiring component 50 it houses. The size of the groove 44A that houses the main line in the cross-sectional view can be formed to be larger than the size of the grooves 44B and 44C that house the branch lines in the cross-sectional view.

[0065] The plurality of wires 52 are housed in the groove 44 in a free state. This free state refers to the plurality of wires 52 being unbound by a binding member. The plurality of wires 52 are individually spread out within the groove 44. The section of the plurality of wires 52 located on the manhole cover 40 is bundled by being housed in the groove 44 and covered by the wiring cover 60. Alternatively, the plurality of wires 52 can be housed in the groove 44 while being bound by a binding member.

[0066] The wiring cover 60 is fixed to the manhole cover 40. The wiring cover 60 closes the opening of the slot 44. The wiring cover 60 is formed, for example, in a plate shape and is arranged so as to span the slot 44 above the slot 44. The portions of the wiring cover 60 that protrude toward either side of the slot 44 are the first end portion 61 and the second end portion 62. The portion of the wiring cover 60 that connects the first end portion 61 and the second end portion 62, that is, the portion that covers the top of the slot 44, is the middle portion 63. The first end portion 61 is mounted on the first mounting portion 45, and the second end portion 62 is mounted on the second mounting portion 46.

[0067] exist Figure 1 In the example shown, wiring covers 60 are installed at one and the other ends of each slot 44 along its length. However, the locations of the wiring covers 60 in the manhole cover 40 are not particularly limited and can be set as appropriate. For example, for short slots, the wiring cover 60 can be installed at only one location. Furthermore, for long slots, the wiring cover 60 can be installed at locations between the ends in addition to at one and the other ends along its length.

[0068] <Wiring Member Holding Structure>

[0069] Apart from Figure 1 and Figure 2 In addition, refer to Figures 3 to 5 , a case where the wiring member 50 is held by the groove 44 and the wiring cover 60 to form a holding structure will be described. Figure 3 and Figure 4 It is a schematic diagram showing a state where the wiring member 50 is housed in the groove 44 . Figure 5 This is a schematic diagram showing a state in which the second end portion 62 of the wiring cover 60 is mounted on the second mounting portion 46 after the wiring member 50 is housed in the groove 44 .

[0070] like Figure 3 and Figure 4As shown, the manhole cover 40 and wiring cover 60 are configured so that, when the first end 61 is attached to the first mounting portion 45 and the second end 62 is not attached to the second mounting portion 46, the second end 62 can be free and free with a space between them. In this disclosure, the state in which the first end 61 is attached to the first mounting portion 45 and the second end 62 is not attached to the second mounting portion 46 is sometimes referred to as a temporary installation state, while the state in which the first end 61 is attached to the first mounting portion 45 and the second end 62 is attached to the second mounting portion 46 is sometimes referred to as a fully installed state. In the temporary installation state, after the wiring member 50 is accommodated in the groove 44, the second end 62 is attached to the second mounting portion 46 to enter the fully installed state. Furthermore, in this example, it is conceivable that the wiring cover 60 may deform when transitioning from the temporary installation state to the fully installed state. Hereinafter, when it is necessary to distinguish between the wiring cover 60 before entering the fully installed state and the wiring cover 60 in the fully installed state, the symbol B may be added and the wiring cover 60B may be referred to. It should be noted that in Figure 4 , one of the two wiring covers 60B is in a temporarily mounted state. The other shows a state before becoming temporarily mounted. The other wiring cover 60B will be in the same temporarily mounted state as the one wiring cover 60B.

[0071] In the temporarily installed state, the direction in which the wiring cover 60B extends and its rigidity allow the second end portion 62 to be free above the second mounting portion 46. More specifically, in the temporarily installed state, the first mounting portion 45 supports the first end portion 61 in a position that allows the second end portion 62 to extend free above the second mounting portion 46. At this point, the wiring cover 60B is cantilevered relative to the manhole cover 40 by attaching the first end portion 61 to the first mounting portion 45. The wiring cover 60B, thus cantilevered, maintains the second end portion 62 free above the second mounting portion 46 through its own rigidity. Therefore, the wiring cover 60B, cantilevered relative to the manhole cover 40, has the rigidity to maintain the second end portion 62 free above the second mounting portion 46.

[0072] The mounting surface 46a of the second mounting portion 46 is flat. The mounting surface 46a of the second mounting portion 46 is located near the bottom of the groove 44 along the height direction of the groove 44, compared to the imaginary plane IP formed by extending the mounting surface 45a of the first mounting portion 45 toward the second mounting portion 46. Figure 4 Even in the wiring cover 60B, which is a flat plate-shaped member with flat surfaces as shown, a space is created between the second end portion 62 and the second mounting portion 46 in the temporarily mounted state.

[0073] The mounting surface 45a of the first mounting portion 45 is an inclined surface whose height from the bottom of the groove 44 decreases as it moves away from the groove 44. By attaching the first end 61 of the flat wiring cover 60B to this mounting surface 45a, the middle portion 63 and second end 62 of the wiring cover 60B extend diagonally upward. This increases the space between the second end 62 and the second mounting portion 46 when the flat wiring cover 60B is temporarily installed, even when the flat wiring cover 60B is used.

[0074] The inclined surface serving as the mounting surface 45a is locally provided along the longitudinal direction of the groove 44, thereby making it easy to identify the position of the first mounting portion 45 in the manhole cover 40. In addition, limiting surfaces intersecting the mounting surface 45a are provided on both sides of the mounting surface 45a along the longitudinal direction of the groove 44. This prevents the wiring cover 60B from being displaced along the longitudinal direction of the groove 44 during welding of the first mounting portion 45 to the first end portion 61. The dimension of the inclined surface along the longitudinal direction of the groove 44 can be, for example, the same as the width dimension of the wiring cover 60B, or can be set to be larger than the width dimension of the wiring cover 60B. However, it is not necessary for the inclined surface serving as the mounting surface 45a to be locally provided along the longitudinal direction of the groove 44. The lateral portion of the groove 44 can also be provided with an inclined surface along the entire longitudinal direction of the groove 44.

[0075] A restricting surface intersecting the mounting surface 45a is provided on the edge of the mounting surface 45a of the first mounting portion 45, opposite the edge on the groove 44 side. The front end of the first end portion 61 of the wiring cover 60B abuts against the restricting surface. This restricts the position of the wiring cover 60B along the width of the groove 44. The restricting surfaces are provided on three sides relative to the mounting surface 45a. Viewed from another angle, the first mounting portion 45 is a partially recessed portion surrounded by the restricting surfaces, with the bottom surface of the recess serving as the mounting surface 45a.

[0076] Here, the description will be made assuming that the mounting structure between the first end portion 61 and the first mounting portion 45 is welded. In this case, the manhole cover 40 and the wiring cover 60B are preferably made of the same resin. For example, the manhole cover 40 and the wiring cover 60B can be formed with PP as the main component. However, it is not necessary for the mounting structure between the first end portion 61 and the first mounting portion 45 to be welded, and it can be set appropriately. For example, the mounting structure between the first end portion 61 and the first mounting portion 45 can be bonded via an adhesive member arranged therebetween. Furthermore, for example, the mounting structure between the first end portion 61 and the first mounting portion 45 can be a locking structure in which a convex portion 47 formed on one side is engaged with a concave portion formed on the other side.

[0077] The edge of the mounting surface 45a on the groove 44 side is preferably welded to the first end portion 61. This prevents the wires 52 from being caught between the mounting surface 45a and the first end portion 61 when the temporary mounting state is changed to the final mounting state after the wires 52 are accommodated.

[0078] The wiring cover 60B is provided at the first and second locations spaced apart along the longitudinal direction of the groove 44. The second end portion 62 of the wiring cover 60B at the first location and the second end portion 62 of the wiring cover 60B at the second location are provided on the same side relative to the groove 44. Figure 4 As shown, in the first and second locations, the wiring member 50 is movable toward the groove 44 from the same side relative to the groove 44 .

[0079] After the wiring member 50 is housed in the groove 44, Figure 5 As shown, an external force F is applied to the wiring cover 60B, causing the second end portion 62 to move to the position where it is attached to the second mounting portion 46. External force F can be considered to be a force applied by a worker directly or by a welding machine. At this time, the portion of the wiring cover 60B including the second end portion 62 bends relative to the first end portion 61 under the action of external force F. Furthermore, the bending of the wiring cover 60B under the action of external force F generates stress in the wiring cover 60B.

[0080] The mounting strength between the first end portion 61 and the first mounting portion 45 in the temporarily mounted state is strong enough to withstand the stress applied to the wiring cover 60B when it is bent by the external force F to mount the second end portion 62 and the second mounting portion 46 in the temporarily mounted state. More specifically, the stress generated by the bending of the wiring cover 60B by the external force F releases the mounted state between the first end portion 61 and the first mounting portion 45. The mounting strength between the first end portion 61 and the first mounting portion 45 in the temporarily mounted state is strong enough to maintain the mounted state even under the application of this stress.

[0081] After the second end portion 62 has been moved to its mounting position relative to the second mounting portion 46, the second end portion 62 is mounted to the second mounting portion 46, thereby achieving a fully mounted state. The mounting structure between the second end portion 62 and the second mounting portion 46 can be appropriately configured. For example, one of the mounting structures described above for the mounting structure between the first end portion 61 and the first mounting portion 45 can be employed. The mounting structure between the second end portion 62 and the second mounting portion 46 can be the same as or different from the mounting structure between the first end portion 61 and the first mounting portion 45.

[0082] The wiring cover 60B, bent by the external force F in the temporary installation state, remains bent even after the external force F is removed in the final installation state. Therefore, in the final installation state, the wiring cover 60 is bent between the first end 61 and the second end 62. In the final installation state, stress due to this bending is applied to the wiring cover 60. The wiring cover 60 is attached to the manhole cover 40 in a stressed state.

[0083] The mounting strength between the first end 61 and the first mounting portion 45, and the mounting strength between the second end 62 and the second mounting portion 46 in the fully mounted state, is strong enough to withstand the stress generated in the wiring cover 60 during the fully mounted state. More specifically, the bending deformation of the wiring cover 60 in the fully mounted state is caused by the second end 62 contacting the mounting surface 46a of the second mounting portion 46. Therefore, the bending deformation of the wiring cover 60 is elastic, or plastic, but with low permanent strain. For example, it is conceivable that the permanent strain is smaller than the initial space between the second end 62 and the second mounting portion 46 in the temporarily mounted state. Consequently, stress associated with this bending deformation remains in the wiring cover 60. This stress tends to dislodge the mounting position between the first end 61 and the first mounting portion 45, and the second end 62 and the second mounting portion 46. The mounting strength between the first end 61 and the first mounting portion 45, and the second end 62 and the second mounting portion 46, is strong enough to maintain the mounting position under this stress.

[0084] If stress associated with bending deformation remains in the wiring cover 60 in the fully installed state, the wiring cover 60 releases this stress by releasing either the first end portion 61 from the first mounting portion 45 or the second end portion 62 from the second mounting portion 46. More specifically, in the released portion, the wiring cover 60 deforms so that a space is created between the end portion of the wiring cover 60 and the mounting portion of the manhole cover 40, allowing the wiring cover 60 to move freely.

[0085] In the fully installed state, the wiring cover 60 can reduce stress associated with bending deformation. Even if either the first end 61 is released from the first mounting portion 45 or the second end 62 is released from the second mounting portion 46, the released end portion can remain in contact with the mounting portion. For example, the stress associated with bending deformation can be reduced in the wiring cover 60 by making the bending deformation of the wiring cover 60 a plastic deformation with a large permanent strain. In this case, it is conceivable that the permanent strain and the initial space between the second end 62 and the second mounting portion 46 in the temporarily installed state are the same as, or larger than, the initial space between the second end 62 and the second mounting portion 46 in the temporarily installed state. Furthermore, for example, the wiring cover 60 can be heated while being placed in the fully installed state, thereby reducing stress associated with bending deformation in the wiring cover 60.

[0086] <Effects of Embodiment 1, etc.>

[0087] According to the vehicle door wiring module 30 constructed as described above, the wiring cover 60 and the inspection hole cover 40 are arranged so that, in a temporarily installed state, they can be free, leaving a space between the second end portion 62 and the second mounting portion 46. Thus, in the temporarily installed state, the wiring member 50 can be easily accommodated in the groove 44 through the space between the second end portion 62 and the second mounting portion 46. Furthermore, by attaching the first end portion 61 to the first mounting portion 45 in the temporarily installed state, the wiring member 50 is less likely to fall out of the groove 44 between the time the wiring member 50 is accommodated in the groove 44 and the time the second end portion 62 is attached to the second mounting portion 46. As described above, a structure for retaining the wiring member 50 using the groove 44 and the wiring cover 60 can be easily formed.

[0088] Furthermore, in the temporarily mounted state, the first mounting portion 45 supports the first end portion 61 in a position that allows the second end portion 62 to extend toward a free position above the second mounting portion 46. Furthermore, the wiring cover 60B, which is cantilevered from the manhole cover 40, has sufficient rigidity to maintain the second end portion 62 free above the second mounting portion 46. This simplifies the structures of the first mounting portion 45, the second mounting portion 46, and the wiring cover 60B.

[0089] Furthermore, the mounting surface 46a of the second mounting portion 46 is located closer to the bottom of the groove 44 along the height direction of the groove 44 than the imaginary plane IP formed by extending the mounting surface 45a of the first mounting portion 45. Thus, when the flat wiring cover 60B is supported in a cantilevered manner on the manhole cover 40, the second end portion 62 can be freed upward from the second mounting portion 46.

[0090] Furthermore, the mounting surface 45a of the first mounting portion 45 is formed as an inclined surface whose height from the bottom of the groove 44 decreases as it moves away from the groove 44. This facilitates increasing the space between the second end 62 of the wiring cover 60B and the second mounting portion 46 when the second end 62 of the wiring cover 60B is in the free position. Furthermore, by providing this inclined surface locally along the longitudinal direction of the groove 44 at a position corresponding to the portion where the wiring cover 60B is located, it becomes easier to identify the location in the manhole cover 40 where the wiring cover 60B is to be mounted.

[0091] Furthermore, wiring covers 60 are provided at first and second locations spaced apart along the longitudinal direction of the groove 44, respectively. The second end portion 62 of the wiring cover 60 at the first location and the second end portion 62 of the wiring cover 60 at the second location are provided on the same side relative to the groove 44. Thus, when the wiring member 50 is received in the groove 44 through the space between the second end portion 62 and the second mounting portion 46, the wiring member 50 can be received in the groove 44 from the same side at both the first and second locations, making it easier to receive the wiring member 50 in the groove 44.

[0092] In addition, the plurality of electric wires 52 are housed in the groove 44 in a state of being free from each other. Thus, by housing the plurality of electric wires 52 in a state of being free from each other in the groove 44, they can be brought into a gathered state. Here, if the plurality of electric wires 52 are in a state of being free from each other, each electric wire 52 can be locally bent at any position. Therefore, it is difficult to ensure that the plurality of electric wires 52 are housed in the groove 44 before closing both ends of the wiring cover 60. In this case, in this example, the first end portion 61 is also mounted on the first mounting portion 45 in a temporarily fixed state, and the second end portion 62 is free above the second mounting portion 46, and the middle portion 63 covers the groove 44. Thus, in the mounting position of the wiring cover 60, it is easy to maintain the plurality of electric wires 52 housed in the groove 44 before closing both ends of the wiring cover 60.

[0093] In addition, in this disclosure, Figures 3 to 5 As shown, the structure of the manhole cover 40 with the wiring cover 60 in a temporarily installed state can be understood as a composite manhole cover 100. Composite manhole cover 100 includes: a manhole cover 40 having a groove 44 formed on its main surface 41a; and a wiring cover 60 having a first end 61 and a second end 62. A first mounting portion 45 and a second mounting portion 46 are provided on the main surface 41a of the manhole cover 40, on either side of the groove 44. In the wiring cover 60, the first end 61 is mounted to the first mounting portion 45, and an intermediate portion 63 between the first end 61 and the second end 62 covers the opening of the groove 44. The second end 62 is spaced apart from the second mounting portion 46.

[0094] According to the composite manhole cover 100 constructed in this manner, in the wiring cover 60, the first end 61 is mounted on the first mounting portion 45, the intermediate portion 63 between the first end 61 and the second end 62 covers the opening of the groove 44, and the second end 62 leaves a space between the second mounting portion 46 and the second end 62. Thus, the wiring member 50 can be easily accommodated in the groove 44 through the space between the second end 62 of the wiring cover 60 and the second mounting portion 46. Furthermore, by attaching the first end 61 of the wiring cover 60 to the first mounting portion 45, the wiring member 50 is less likely to fall out of the groove 44 between the time the wiring member 50 is accommodated and the time the second end 62 of the wiring cover 60 is attached to the second mounting portion 46. As described above, a structure for retaining the wiring member 50 using the groove 44 and the wiring cover 60 can be easily formed.

[0095] [Modification]

[0096] Figure 6 2 is a cross-sectional view showing a first modified example of the door wiring module 30 . Figure 7 1 is a cross-sectional view showing a first modified example of the composite manhole cover 100. The composite manhole cover 200 of the first modified example is used in the vehicle door wiring module 130 of the first modified example.

[0097] This example is also similar to the previous example in that wiring covers 60 are provided at first and second locations spaced apart along the length of the groove 44. This example differs from the previous example in that the second end 62 of the wiring cover 60 at the first location and the second end 62 of the wiring cover 60 at the second location are located on opposite sides of the groove 44. With the door wiring module 130 and composite manhole cover 200 constructed in this manner, when the second end 62 of the wiring cover 60 is attached to the second mounting portion 46 after the wiring member 50 is housed, the first and second locations are closed on opposite sides of the groove 44, making it difficult for the wiring member 50 to fall out of the groove 44.

[0098] Figure 8 2 is a cross-sectional view showing a second modified example of the door wiring module 30 . Figure 9 1 is a cross-sectional view showing a second modified example of the composite manhole cover 100. The composite manhole cover 300 of the second modified example is used in the vehicle door wiring module 230 of the second modified example.

[0099] In this example, the mounting surface 246a of the second mounting portion 246 is formed as an inclined surface whose height increases as it moves away from the bottom of the groove 244. This reduces stress concentration on the wiring cover 60 when the device is fully installed. The inclination of the mounting surface 45a of the first mounting portion 45 and the inclination of the mounting surface 246a of the second mounting portion 246 can be the same, or one can be greater than the other.

[0100] The inclined surface serving as the mounting surface 246a may be provided partially along the longitudinal direction of the groove 244, similarly to the inclined surface serving as the mounting surface 45a. The inclined surface serving as the mounting surface 246a may also be provided entirely along the longitudinal direction of the groove 244.

[0101] Here, in the width direction of the groove 244, the size of the inclined surface as the mounting surface 246a is set to be approximately the same as the length of the second end portion 62. A guide inclined surface is provided on the side of the inclined surface as the mounting surface 246a, which is inclined in the opposite direction to the inclined surface. Figure 9 As shown, when the wiring member 50 is accommodated in the groove 244 through the space between the second end 62 and the second mounting portion 246, the wiring member 50 is easily guided into the space between the second end 62 and the second mounting portion 246. Furthermore, it is possible to prevent the area where the thickness of the manhole cover 40 increases from becoming larger. From the perspective of guiding the wiring member 50 between the second end 62 and the second mounting portion 246, a flat surface having the same height as the top of the inclined surface serving as the mounting surface 246a can be extended to the side. Furthermore, the inclined surface serving as the mounting surface 246a can be longer than the length of the second end 62 to the extent that the wiring member 50 is accommodated.

[0102] In addition, in this example, the portion of the bottom of the groove 244 on the side of the first mounting portion 45 along the width direction of the groove 244 is configured as an inclined surface whose depth increases as it moves toward the first mounting portion 45. As a result, the wiring member 50 housed in the groove 244 on the side of the first mounting portion 45 is less likely to overflow from the groove 244, and is prevented from being bitten between the first end portion 61 of the wiring cover 60 and the first mounting portion 45. Here, the portion of the bottom of the groove 244 along the width direction that is closer to the first mounting portion 45 than the middle portion 63 is configured as an inclined surface. Alternatively, the entire bottom of the groove 244 along the width direction may be configured as an inclined surface. The inclination of the mounting surface 45a of the first mounting portion 45 and the inclination of the bottom of the groove 244 may be the same, or one may be larger than the other.

[0103] Figure 10 It is a cross-sectional view showing a third modified example of the door wiring module 30 . Figure 11 1 is a cross-sectional view showing a third modified example of the composite manhole cover 100. The composite manhole cover 400 of the third modified example is used in the vehicle door wiring module 330 of the third modified example.

[0104] In this example, the mounting structure between the first end portion 61 and the first mounting portion 345, and the mounting structure between the second end portion 62 and the second mounting portion 346, are not welded. Instead, they utilize locking structures using protrusions 45b and 46b and recesses 61a and 62a. Here, protrusions 45b and 46b are provided on the first mounting portion 345 and the second mounting portion 346, respectively. The protrusion 45b of the first mounting portion 345 protrudes from the mounting surface 45a, while the protrusion 46b of the second mounting portion 346 protrudes from the mounting surface 246a. Through-holes serving as recesses 61a and 62a are formed in the first end portion 61 and the second end portion 62, respectively. The protrusion 45b is inserted and locked into the recess 61a, thereby mounting the first end portion 61 and the first mounting portion 345. The protrusion 46b is inserted and locked into the recess 62a, thereby mounting the second end portion 62 and the second mounting portion 346.

[0105] In the temporary installation state, it is sufficient as long as the front end of the second end portion 62 and the mounting surface 246a of the second mounting portion 346 are free with a space between them. The protrusion 46b and the middle side portion of the second end portion 62 that is closer to the front end can be in contact. In this case, Figure 11 As shown by the double-dashed line, the wiring cover 360B can be deformed so that a space is left between the second end 62 of the wiring cover 360B and the protrusion 46b, and the wiring cover 360B is opened. Of course, in the initial state of the temporary installation state, the wiring cover can also be free with a space left between the second end 62 and the protrusion 46b.

[0106] Figure 12 It is a cross-sectional view showing a fourth modified example of the door wiring module 30 . Figure 13 1 is a cross-sectional view showing a fourth modified example of the composite manhole cover 100. The composite manhole cover 500 of the fourth modified example is used in the vehicle door wiring module 430 of the fourth modified example.

[0107] In this example, the shape of the wiring cover 460B creates a state in which the second end portion 62 is free from the second mounting portion 46 in a temporary installation state. The height of the mounting surface 46a of the second mounting portion 46 coincides with the height of an imaginary plane IP formed by extending the mounting surface 445a of the first mounting portion 445 toward the second mounting portion 46. Furthermore, both mounting surfaces 445a and 46a are flat surfaces. A curved portion is provided in the wiring cover 460B midway between the first end portion 61 and the free position of the second end portion 62. Here, a curved portion 64 is provided between the first end portion 61 and the intermediate portion 63. Even in the fully installed wiring cover 460, a trace 64a of this curved portion 64 remains. That is, the wiring cover 460 is uneven and skewed in the area where the trace 64a is located. Furthermore, it is conceivable that a fold may remain as the trace 64a.

[0108] Figure 14 1 is a cross-sectional view showing a fifth modified example of the composite manhole cover 100 .

[0109] In the composite manhole cover 600 of the fifth modified example, the portion of the wiring cover 560B including the second end portion 562 is bent into a V-shape. A space is left between the front end of the second end portion 562 and the second mounting portion 46. The wiring cover 560B gradually approaches the second mounting portion 46 from the front end of the second end portion 562 toward the bottom of the V-shape. In this case, Figure 14 As shown by the two-dot chain line, the wiring cover 60B can be deformed to open the V-shaped bottom portion and create a space between the second mounting portion 46. In the wiring cover 560B, the V-shaped bottom portion is welded to the second mounting portion 46, allowing for a fully installed state. In the wiring cover 560B, the portion closer to the front end of the second end portion 562 than the V-shaped bottom portion is bent so as to contact the mounting surface 46a of the second mounting portion 46 and welded to the mounting surface 46a of the second mounting portion 46, allowing for a fully installed state.

[0110] It should be noted that the configurations described in the above-mentioned embodiments and modifications may be appropriately combined as long as they do not contradict each other.
