Description

[Technical Field]

[0001] The present disclosure relates to door components, grommets, and wiring modules. [Background technology]

[0002] A grommet is usually attached to a wiring member that connects a door to a vehicle body. As an assembly structure between this grommet and a door panel, there are two types: a structure in which the grommet is passed through a through-hole formed in the door panel, as described in Patent Document 1, for example, and a structure in which the grommet is arranged along the surface of the door panel, as described in Patent Document 2, for example. The grommet described in Patent Document 2 is also called a through-hole-less grommet because it does not need to be passed through a through-hole formed in the door panel like the grommet described in Patent Document 1.

[0003] Furthermore, to prevent water from entering the vehicle interior, a weatherstrip is usually attached to the door panel along the periphery of the door panel. When the grommet is a non-penetration grommet, the weatherstrip is disposed on the surface facing the vehicle body so as to cross the non-penetration grommet, as described in Patent Document 2. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-217229 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-27640 Summary of the Invention [Problem to be solved by the invention]

[0005] When a weatherstrip and a non-penetration grommet such as that disclosed in Patent Document 2 are assembled to a door panel, if the weatherstrip is assembled to the door panel first, the non-penetration grommet must be passed between the door panel and the weatherstrip. This leaves room for improvement in ease of assembly.

[0006] Therefore, an object of the present invention is to provide a technique that can improve the ease of assembling door parts to a door panel. [Means for solving the problem]

[0007] The door part of the present disclosure comprises a grommet that is assembled to a door panel so as to cross a portion of its periphery, and a weatherstrip that is assembled to the door panel so as to extend along the periphery, wherein the grommet includes a first tubular portion and a second tubular portion that are formed to open in different directions from each other, the weatherstrip has a first end and a second end along its longitudinal direction, and the first end of the weatherstrip is fitted into the first tubular portion, and the second end is fitted into the second tubular portion. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to improve the ease of assembling door components to door panels. [Brief explanation of the drawings]

[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The door parts of the present disclosure are as follows.

[0012] (1) A door component comprising: a grommet assembled to a door panel so as to cross a portion of its periphery; and a weatherstrip assembled to the door panel so as to extend along the periphery, wherein the grommet includes a first tubular portion and a second tubular portion formed to open in different directions from each other; the weatherstrip has a first end and a second end along its length, the first end of the weatherstrip being fitted into the first tubular portion and the second end being fitted into the second tubular portion. The first end of the weatherstrip is fitted into the first tubular portion, and the second end is fitted into the second tubular portion. This allows the end of the weatherstrip assembled to the door panel first to be fitted into the grommet assembled to the door panel later, or the end of the weatherstrip assembled to the door panel later to be fitted into the grommet assembled to the door panel first, or both to be assembled to the door panel with the end of the weatherstrip fitted into the grommet. This improves the ease of assembling the door parts to the door panel.

[0013] (2) In the door component of (1), the grommet may have a lip extending circumferentially on at least a portion of the inner surface of the first tubular portion facing the vehicle body, and the lip may locally crush a portion of the first end of the weatherstrip when the door is closed. This improves the sealing between the grommet and the weatherstrip.

[0014] (3) In the door component of (1) or (2), the grommet may have a flange extending from the vehicle body side of the opening of the first cylindrical portion toward the outside of the first cylindrical portion, and the flange may be in close contact with the outer surface of the weatherstrip when the door is closed. This improves the sealing performance between the grommet and the weatherstrip.

[0015] (4) In the door part of any one of (1) to (3), there may be a section between the first end and the second end of the weatherstrip where the weatherstrip is discontinued, and the grommet may be provided with a weatherstrip substitute portion that waterproofs the section in place of the weatherstrip. This allows the weatherstrip to be shortened.

[0016] (5) In the door component of (4), the weatherstrip replacement part may have a door-facing convex part that protrudes toward the door panel and a vehicle body-facing convex part that protrudes toward the vehicle body, the door-facing convex part and the vehicle body-facing convex part connect the first tubular part and the second tubular part and are elastically deformable so as to be crushed, the door-facing convex part may be always in a crushed state when the grommet is attached to the door panel, and the vehicle body-facing convex part may be elastically deformed so as to be crushed when the door is closed and elastically restored when the door is open. This improves the watertightness of the weatherstrip replacement part.

[0017] (6) The door component of (4) or (5) may further include a wiring member passed through the grommet, and the wiring member may pass through the inside of the grommet so as to overlap the weatherstrip replacement portion. This prevents the wiring member from being involved in the collapse of the weatherstrip, and stabilizes the collapse of the weatherstrip.

[0018] (7) In the door component of any one of (1) to (6), the weatherstrip may be formed as a single piece that can surround the periphery of the door panel from the first end to the second end. This allows the weatherstrip to be a ring-shaped piece that surrounds the periphery of the door panel, but the linear weatherstrip can be bent and used as is, eliminating the need for an endless ring-shaped weatherstrip.

[0019] (8) The grommet disclosed herein is a grommet that is assembled to a door panel across its periphery and includes a first tubular portion and a second tubular portion that open in different directions. The first tubular portion and the second tubular portion are formed to allow a first end and a second end of a weatherstrip, which is assembled to the door panel along its periphery, to be fitted into the first tubular portion, respectively. The first end of the weatherstrip can be fitted into the first tubular portion, and the second end can be fitted into the second tubular portion. This allows the end of a weatherstrip that is assembled to the door panel first to be fitted into a grommet that is later assembled to the door panel, or the end of a weatherstrip that is later assembled to the door panel to be fitted into a grommet that is already assembled to the door panel, or both can be assembled to the door panel with the end of the weatherstrip fitted into the grommet. This improves the ease of assembly of door parts to the door panel.

[0020] (9) The wiring module of the present disclosure includes the grommet of (8) and a wiring member passed through the grommet.

[0021] [Details of the embodiments of the present disclosure] Specific examples of the door component, grommet, and wiring module of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0022] [Embodiment 1] Hereinafter, a door part, a grommet, and a wiring module according to the first embodiment will be described.

[0023] <Door> First, a door in a vehicle will be described with reference to Fig. 1. Fig. 1 is a schematic plan view showing a door component according to a first embodiment and a door panel 12 to which the door component is to be assembled.

[0024] The door 10 is formed into a flat shape overall, and is a part of a vehicle that can be opened and closed to separate the interior and exterior of the vehicle. Hereinafter, the open and closed states of the door 10 in the vehicle will simply be referred to as the open state and the closed state. The door 10 may be a driver's door, a passenger's door, a rear seat door, or the like. In the following, the door 10 will be described as a side door. The door may also be a back door, or the like. In the following, the door 10 will be described as a hinged door. The door may also be a sliding door, or the like. The door 10 includes a door panel 12 and door components.

[0025] The door panel 12 comprises an outer panel 13 and an inner panel 14. The outer panel 13 is provided on the portion of the door 10 facing the outside of the vehicle and, together with the body, constitutes the exterior of the vehicle. The inner panel 14 is provided on the passenger compartment 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 portion that faces the passenger compartment when the door is closed. A space capable of accommodating a window or electrical equipment is provided between the inner plate portion 15 and the outer panel 13. The side plate portion 16 is a portion that extends from the edge of the inner plate portion 15 toward the outer panel 13. In particular, here, the side plate portion 16 extends from the edge of the inner plate portion 15 that is located on the front side of the vehicle (the side where the hinge is located in the case of a hinged door). The side plate portion 16 partitions the space capable of accommodating a window or electrical equipment.

[0026] The door component is a component that is assembled into the door 10. The door component includes a grommet 20, a weather strip 50, and a wiring member 60.

[0027] The grommet 20 is a so-called non-penetration grommet. The grommet 20 is assembled to the inner panel 14 of the door panel 12 so as to cross part of the periphery. The grommet 20 is attached to the side panel portion 16. A part of the weatherstrip 50 is attached to the grommet 20. The grommet 20 includes a first tubular portion 32 and a second tubular portion 33. The first tubular portion 32 and the second tubular portion 33 open in different directions from each other. Here, the first tubular portion 32 and the second tubular portion 33 open in opposite directions from each other. The weatherstrip 50 is inserted into the first tubular portion 32 and the second tubular portion 33.

[0028] The weatherstrip 50 is assembled to the door panel 12 so as to extend along the periphery. The weatherstrip 50 is assembled to the inner panel 14 so as to extend along the periphery. The weatherstrip 50 has a first end 51 and a second end 52. The first end 51 is fitted into the first tubular portion 32. The second end 52 is fitted into the second tubular portion 33. Here, the weatherstrip 50 is formed as a single continuous piece from the first end 51 to the second end 52. In other words, one end of the single linear weatherstrip 50 is the first end 51, and the other end is the second end 52. The weatherstrip 50 is assembled to surround the door panel 12. The length of the weatherstrip 50 is the same as (slightly shorter in this case) the length of the periphery of the door panel 12.

[0029] The wiring member 60 is a member that supplies power to devices incorporated in the door 10 and transmits signals between devices incorporated in the door 10 and devices incorporated in the vehicle body. Here, the wiring member 60 includes a plurality of electric wires 62. The wiring member 60 may also include an optical fiber cable, etc. The path and connection partners of the wiring member 60 in the vehicle are not particularly limited, but the following path and connection partners are conceivable, for example. That is, one end of the wiring member 60 is disposed in the vehicle body. A connector C1 is provided at one end of the wiring member 60. This connector C1 is connected to a vehicle body connector provided on a wiring member on the vehicle body side that extends from a battery, an electronic control unit, etc. The other end of the wiring member 60 is disposed in the door 10. The other end of the wiring member 60 is connected to a device incorporated in the door 10. The wiring member 60 and the device provided in the door 10 may be connected, for example, by a connector. In this case, a connector C2 is preferably provided at the other end of the wiring member 60.

[0030] An intermediate portion of the wiring member 60 is stretched between the vehicle body and the door 10. More specifically, the wiring member 60 extends from one end to the other end through a through hole provided in the vehicle body and extends toward the side plate portion 16 of the door panel 12. After reaching the side plate portion 16, the wiring member 60 extends along the door panel 12 from the side plate portion 16 toward the inner plate portion 15. The section of the wiring member 60 from the through hole provided in the vehicle body to the portion that reaches the inner plate portion 15 is covered and protected by the grommet 20. A plurality of electric wires 62 extend integrally from the portion of the wiring member 60 to which the grommet 20 is attached. After reaching the inner plate portion 15, the wiring member 60 extends from the grommet 20 and extends to a position on the inner plate portion 15 to which the plurality of electric wires 62 branch off and are connected.

[0031] In addition to the above-mentioned devices to which the wiring member 60 is connected, for example, a decorative trim is also incorporated into the door 10. The decorative trim is provided on the part of the door 10 facing the interior of the vehicle and is a part that constitutes the interior appearance of the vehicle. For example, a door handle, an operating section for on-board devices, etc. are attached to the decorative trim. The part of the wiring member 60 that extends from the grommet 20 and runs along the inner panel portion 15 is covered by the decorative trim.

[0032] The door component will be described in detail below with reference to Figs. 2 to 11 in addition to Fig. 1. Fig. 2 is a perspective view showing the door component according to the first embodiment. Fig. 3 is a front view showing the door component according to the first embodiment. Fig. 4 is a side view showing the door component according to the first embodiment. Fig. 5 is a bottom view showing the door component according to the first embodiment. Fig. 6 is a rear view showing the door component according to the first embodiment. Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 2. Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 2. Fig. 9 is an enlarged view of region A1 in Fig. 3. Fig. 10 is a cross-sectional view taken along line VII-VII in Fig. 9. Fig. 11 is a cross-sectional view taken at the same position as Fig. 10, showing the door component in a closed state.

[0033] <Grommet> Here, grommet 20 includes outer member 21 and inner member 44. Outer member 21 is a molded product made of an elastic material such as elastomer. Inner member 44 is a molded product made of a material such as resin or metal. Inner member 44 has higher rigidity than outer member 21. Here, outer member 21 and inner member 44 are molded separately and then can be attached.

[0034] The outer member 21 includes a door mounting portion 22, a protective tube portion 40, and a vehicle body mounting portion .

[0035] The door mounting portion 22 is a portion that is attached to the door panel 12. The door mounting portion 22 is attached to the side plate portion 16. The door mounting portion 22 has a base portion 23, a drawer tubular portion 31, a first tubular portion 32, a second tubular portion 33, a weatherstrip replacement portion 34, and flanges 38 and 39.

[0036] The base portion 23 is formed flat and is attached so as to extend over the surface of the side plate portion 16. The base portion 23 has a wiring accommodating portion 24 and an extending portion 25.

[0037] The wiring accommodating portion 24 is a portion that accommodates the wiring member 60. The wiring accommodating portion 24 accommodates a portion of the wiring member 60 that extends along the side plate portion 16. The wiring accommodating portion 24 is formed in a cylindrical shape. One opening of the wiring accommodating portion 24 opens to one surface of the base portion 23. One opening of the wiring accommodating portion 24 is formed in the shape of a circular hole. The other opening of the wiring accommodating portion 24 opens to the side surface of the base portion 23. The other opening of the wiring accommodating portion 24 is formed in the shape of a flat elongated hole. The other opening of the wiring accommodating portion 24 communicates with the drawn-out cylindrical portion 31. The extension portion 25 is a portion that extends outward from the periphery of the wiring accommodating portion 24.

[0038] As shown in FIG. 5 , the base portion 23 is formed so that a portion thereof serves as a hinge portion 26 so as to be openable and closable. Here, the hinge portion 26 is the peripheral edge of the extension portion 25 that is located on the inside along the inside-outside direction of the vehicle and extends vertically. A vehicle body side portion 27 and a door side portion 28 of the base portion 23 are connected via the hinge portion 26. In the closed state, the vehicle body side portion 27 is located closer to the vehicle body 80 than the door side portion 28, and the door side portion 28 is located closer to the door panel 12 than the vehicle body side portion 27. The wiring housing 24 is divided into the vehicle body side portion 27 and the door side portion 28. In other words, a portion of the wiring housing 24 is provided in the vehicle body side portion 27, and another portion is provided in the door side portion 28. The extension portion 25 is also divided into the vehicle body side portion 27 and the door side portion 28. Since the base portion 23 can be opened and closed around the hinge portion 26, the wiring member 60 can be easily housed in the wiring housing portion 24 and the protective tube portion 40.

[0039] Here, the portion of the wiring member 60 that extends along the side plate portion 16 is accommodated in the wire accommodating portion 24, and the portion that curves and extends from the side plate portion 16 toward the inner plate portion 15 is accommodated in the drawn-out tubular portion 31. Here, the portion of the wiring member 60 that is accommodated in the wire accommodating portion 24 and the portion that is accommodated in the drawn-out tubular portion 31 are accommodated in the inner member 44. Therefore, the wire accommodating portion 24 and the drawn-out tubular portion 31 are formed to be able to accommodate the inner member 44. The shapes of the wire accommodating portion 24 and the drawn-out tubular portion 31 are formed to correspond to the shape of the inner member 44. The wire accommodating portion 24 is able to cover one end portion of the inner member 44 from both sides. The wire accommodating portion 24 in the vehicle body side portion 27 is formed flat as shown in FIG. 2. One opening is formed in the wire accommodating portion 24 in the vehicle body side portion 27. The wire accommodating portion 24 in the door side portion 28 is formed convex as shown in FIG. 6. The drawn-out tubular portion 31 is able to insert the other end portion of the inner member 44.

[0040] The extension portion 25 is flat at both the vehicle body side portion 27 and the door side portion 28. The vehicle body side portion 27 of the extension portion 25 extends along the same plane as the vehicle body side portion 27 of the wiring accommodating portion 24. The door side portion 28 of the extension portion 25 extends flat from the periphery of the door side portion 28 of the wiring accommodating portion 24. The door side portion 28 of the wiring accommodating portion 24 protrudes more toward the door panel 12 than the door side portion 28 of the extension portion 25.

[0041] Mounting holes 29 are formed in the base portion 23. Bolts, clips, etc. are passed through the mounting holes 29. The base portion 23 is attached to the door panel 12 by fastening or engaging the bolts, clips, etc. passed through the mounting holes 29 to the door panel 12. Here, two mounting holes 29 are formed in the base portion 23. The two mounting holes 29 are formed in the extension portion 25. The two mounting holes 29 are provided separately, one above and one below the wiring accommodating portion 24 in the vertical direction. The two mounting holes 29 are formed so as to be located on the same side (here, the outside along the inward / outward direction of the vehicle) with respect to the first tubular portion 32 and the second tubular portion 33.

[0042] The wiring accommodating portion 24 has mating holes 30 formed therein. Two mating holes 30 are formed in each of the vehicle body portion 27 and the door portion 28. The mating holes 30 formed in the vehicle body portion 27 and the door portion 28 are formed at corresponding positions. The mating holes 30 are formed so as to recess from the internal space that accommodates the wiring member 60 toward one surface (the surface of the vehicle body portion 27) and the other surface (the surface of the door portion 28) of the base portion 23. Here, the mating holes 30 penetrate through to both the one surface and the other surface of the base portion 23. The mating holes 30 are formed so that protrusions 47 formed on the outer surface of the inner member 44 can fit into them. The two mating holes 30 are formed at positions spaced apart in the vertical direction. The mating holes 30 are formed at positions close to the hinge portion 26 (slightly outward from the hinge portion 26).

[0043] The draw-out tube portion 31 is connected to the edge of the base portion 23 that forms the hinge portion 26. The draw-out tube portion 31 accommodates the portion of the wiring member 60 that curves and extends from the side plate portion 16 toward the inner plate portion 15. The draw-out tube portion 31 is tubular with a flat cross section and a curved central axis. The draw-out tube portion 31 communicates with the wiring accommodation portion 24. The draw-out tube portion 31 does not open or close via the hinge portion 26. When the base portion 23 is opened from the hinge portion 26, the protective tube portion 40 and the cylindrical draw-out tube portion 31 are aligned and extend on the same side, as shown by the two-dot chain line in Figure 5. At this time, one opening of the draw-out tube portion 31 appears between the vehicle body side portion 27 and the door side portion 28, next to the hinge portion 26. This allows the other end of the inner member 44 to be easily inserted into the draw-out tube portion 31.

[0044] The first tubular portion 32 and the second tubular portion 33 are provided on the extension portion 25. The first tubular portion 32 and the second tubular portion 33 are provided separately on the vertically upper and lower sides of the wire housing portion 24. Here, when the grommet 20 is attached to the door 10, the first tubular portion 32 is positioned vertically above the wire housing portion 24, and the second tubular portion 33 is positioned vertically below. The first tubular portion 32 and the second tubular portion 33 extend in the vertical direction. The first tubular portion 32 opens vertically upward, and the second tubular portion 33 opens vertically downward. Here, the opening of the first tubular portion 32 and the opening of the second tubular portion 33 are provided offset from each other in the interior / exterior direction of the vehicle. The opening of the first tubular portion 32 is positioned outward in the interior / exterior direction of the vehicle than the opening of the second tubular portion 33. The first tubular portion 32 and the second tubular portion 33 extend while gently curving between the opening of the first tubular portion 32 and the opening of the second tubular portion 33. The opening of the first tubular portion 32 and the opening of the second tubular portion 33 may be provided at the same position along the inside-outside direction of the vehicle.

[0045] FIG. 8 shows the cross-sectional shape of the second tubular portion 33. The cross-sectional shape of the second tubular portion 33 will be described below with reference to FIG. 8. The cross-sectional shape of the first tubular portion 32 is also formed to have a similar shape to the cross-sectional shape of the second tubular portion 33. As shown in FIG. 8, the second tubular portion 33, like the base portion 23, is divided into a vehicle body side portion 27 and a door side portion 28. In the vehicle body side portion 27, the second tubular portion 33 protrudes from the extension portion 25 onto the surface of the extension portion 25. In the door side portion 28, the second tubular portion 33 protrudes from the extension portion 25 onto the surface of the extension portion 25. The thickness of the second tubular portion 33 is approximately the same as the thickness of the extension portion 25. The amount of protrusion from the extension portion 25 at the vehicle body side portion 27 of the second tubular portion 33 is greater than the amount of protrusion from the extension portion 25 at the door side portion 28. Most of the weatherstrip 50 fits within the vehicle body side portion 27 of the second tubular portion 33. The door-side portion 28 of the second tubular portion 33 covers the vehicle body-side portion 27. The second tubular portion 33 is crushed together with the weatherstrip 50 in the closed state.

[0046] The weatherstrip substitute portion 34 is a portion that waterproofs the discontinuous section of the weatherstrip 50 in place of the weatherstrip 50. Here, the weatherstrip substitute portion 34 connects the first tubular portion 32 and the second tubular portion 33. The weatherstrip substitute portion 34 has a body-facing protrusion 35 and a door-facing protrusion 36. The body-facing protrusion 35 and the door-facing protrusion 36 are each elastically deformable so as to be crushed. As shown in FIG. 7 , the thickness of the body-facing protrusion 35 and the door-facing protrusion 36 are each approximately the same as the thickness of the base portion 23. For this reason, the interior of the body-facing protrusion 35 and the interior of the door-facing protrusion 36 are hollow.

[0047] The vehicle body-facing convex portion 35 protrudes from the base portion 23 toward the vehicle body 80. The vehicle body-facing convex portion 35 elastically deforms so as to be crushed in the closed state and elastically returns to its original shape in the open state. The vehicle body-facing convex portion 35 connects the first tubular portion 32 and the second tubular portion 33 in the vehicle body side portion 27. The vehicle body-facing convex portion 35 is formed to have the same size and shape as the first tubular portion 32 and the second tubular portion 33 in the vehicle body side portion 27. Therefore, in the vehicle body side portion 27, a groove having the same cross-sectional shape is formed so as to cross the base portion 23. One end of the groove is the vehicle body side portion 27 of the first tubular portion 32. The other end of the groove is the vehicle body side portion 27 of the second tubular portion 33. The middle portion of the groove is the vehicle body-facing convex portion 35.

[0048] The door-facing protrusion 36 protrudes from the base portion 23 toward the door panel 12. The door-facing protrusion 36 is always in a collapsed state when the grommet 20 is attached to the door panel 12. The door-facing protrusion 36 connects the first tubular portion 32 and the second tubular portion 33 in the door-side portion 28. One end of the door-facing protrusion 36 connects to the first tubular portion 32 at the upper extension portion 25 of the wiring accommodating portion 24. The other end of the door-facing protrusion 36 connects to the second tubular portion 33 at the lower extension portion 25 of the wiring accommodating portion 24. An intermediate portion of the door-facing protrusion 36 crosses the wiring accommodating portion 24. The door-facing protrusion 36 is formed larger than the door-side portions 28 of the first tubular portion 32 and the second tubular portion 33. The door-facing protrusion 36 has the same size and shape as the vehicle body-facing protrusion 35 and is formed line-symmetrically with the vehicle body-facing protrusion 35. Therefore, in the door-side portion 28, a groove whose cross-sectional shape changes is formed so as to cross the base portion 23. One end of the groove is the door-side portion 28 of the first cylindrical portion 32. The other end of the groove is the door-side portion 28 of the second cylindrical portion 33. The middle portion of the groove is the door-facing protrusion 36. The size of the groove at the middle portion is larger than the sizes of the groove at one end and the other end.

[0049] 7, an inner member 44 is interposed between the body-facing protrusion 35 and the door-facing protrusion 36. The inner member 44 supports the deformation of the body-facing protrusion 35 and the door-facing protrusion 36.

[0050] A lip 37 is formed on the inner surface of the first tubular portion 32 (see FIGS. 8 to 11). The lip 37 is formed on at least the vehicle body side portion 27 of the inner surface of the first tubular portion 32. The lip 37 is formed to extend in the circumferential direction of the inner surface of the first tubular portion 32. In this example, the lip 37 is formed on the vehicle body side portion 27, but not on the door side portion 28. Therefore, the lip 37 has one end and the other end in the circumferential direction. The lip 37 is formed on a portion of the weatherstrip 50 facing a tubular portion 53 (described later). In the closed state, the lip 37 locally crushes a portion of the first end 51 of the weatherstrip 50 in the longitudinal direction (see FIG. 11). A similar lip 37 is also formed on the inner surface of the second tubular portion 33 (see FIG. 3). In the closed state, the lip 37 formed on the second tubular portion 33 locally crushes a portion of the second end 52 of the weatherstrip 50 in the longitudinal direction.

[0051] The flange 38 extends from the vehicle body side portion 27 of the opening of the first tubular portion 32. The flange 38 is formed to extend outward from the vehicle body side portion 27 at the opening edge of the first tubular portion 32. The flange 38 protrudes obliquely from the first tubular portion 32 toward the weatherstrip 50 as it moves axially outward from the first tubular portion 32. As shown in FIG. 11 , the flange 38 comes into close contact with the outer surface of the collapsed weatherstrip 50 in the closed state. In particular, here, the flange 38 comes into close contact with the outer surface of the weatherstrip 50 that is collapsed and curved by the lip 37 in the closed state. Like the first tubular portion 32, the second tubular portion 33 is also provided with a flange 38.

[0052] More specifically, the flange 38 is formed thinner than the first tubular portion 32. The flange 38 protrudes from the radially outer surface of the first tubular portion 32. As a result, the tip of the flange 38 elastically deforms radially outward from the first tubular portion 32, with the base end connected to the first tubular portion 32 serving as a fulcrum. The tip of the flange 38 is cut obliquely with respect to the axial direction of the first tubular portion 32 so as to extend from the inside to the outside of the first tubular portion 32. As a result, the tip surface of the flange 38 is larger than when the tip of the flange 38 is cut in a direction perpendicular to the axial direction of the first tubular portion 32. The portion of the weatherstrip 50 adjacent in the longitudinal direction to the portion crushed by the lip 37 is curved so as to bulge toward the vehicle body 80. This curved portion comes into contact with the flange 38 and pushes the tip outward. As a result, the tip of the flange 38 fits tightly to this curved portion. Preferably, if the tip surface of the flange 38 is formed in a shape that faces from the inside to the outside of the first tubular portion 32 , the tip surface of the flange 38 will come into surface contact with the outer surface of the weatherstrip 50 .

[0053] Because the flange 38 is thinner than the first tubular portion 32, the step at the boundary between the first tubular portion 32 and the flange 38 is small. Therefore, the weatherstrip 50 can fill the step between the first tubular portion 32 and the flange 38 by its own slight elastic deformation (for example, elastic deformation of the tubular portion 53). As described above, this, combined with the fact that the tip of the flange 38 is formed in an obliquely cut shape, allows the weatherstrip 50 to come into contact with the first tubular portion 32 and the flange 38 with as little gap as possible.

[0054] 10 and 11 are cross-sectional views of the weatherstrip 50 cut along a straight line (line XX in FIG. 9 ) at the portion where the weatherstrip 50 extends while bending. Therefore, in FIG. 11 , which shows the closed state, there are portions along the longitudinal direction of the weatherstrip 50 where there are gaps between the vehicle body 80 and the first tubular portion 32 and the weatherstrip 50. However, in portions along the circumferential direction of the weatherstrip 50 that are different from the portions shown in the cross section in FIG. 11 , the vehicle body 80, the first tubular portion 32, and the weatherstrip 50 are in close contact. In other words, the cross-sectional portion shown in FIG. 11 includes portions that are slightly shifted from the portions where the vehicle body 80, the first tubular portion 32, and the weatherstrip 50 are in close contact. In reality, the vehicle body 80, the grommet 20, and the weatherstrip 50 are in continuous close contact along the longitudinal direction of the weatherstrip 50. Furthermore, the flange 38 is also present at the boundary between the grommet 20 and the weatherstrip 50 (near the opening of the first tubular portion 32), thereby reducing the gap between the grommet 20 and the vehicle body 80.

[0055] The flange 39 is provided on the outer edge of the base portion 23. The flange 39 is provided on the outer edge of the vehicle body side portion 27 of the base portion 23. The flange 39 is connected to a flange 38 provided on the outside of the first tubular portion 32 and a flange 38 provided on the outside of the second tubular portion 33. The flange 39 protrudes obliquely toward the door 10. The thickness of the flange 39 is thinner than the thickness of the base portion 23 and is formed to be the same thickness as the flange 38. The flange 39 protrudes toward the door 10 further than the door side portion 28 of the base portion 23. When the grommet 20 is attached to the door panel 12, the flange 39 elastically deforms to fit along the door panel 12 and comes into close contact with the door panel 12.

[0056] 11, which shows the closed state, there are gaps between the door panel 12 and the first tubular portion 32 and weatherstrip 50 along the longitudinal direction of the weatherstrip 50. This is because, as described above, FIG. 11 is a cross-sectional view of the weatherstrip 50 taken along a straight line (line XX in FIG. 9) along which the weatherstrip 50 curves and extends. Similar to the gaps between the vehicle body 80 and the grommet 20 and weatherstrip 50, there is continuous tight contact between the door panel 12 and the grommet 20 and weatherstrip 50 along the longitudinal direction of the weatherstrip 50. At the boundary between the grommet 20 and the weatherstrip 50 (near the opening of the first tubular portion 32), the flanges 38 and 39 are in tight contact with the periphery of the weatherstrip 50, and the flange 39 is in tight contact with the door panel 12, thereby preventing water from entering.

[0057] The protective tubular portion 40 is provided so as to protrude from the surface of the vehicle body side portion 27 of the wiring housing portion 24. The protective tubular portion 40 is in communication with the wiring housing portion 24. The protective tubular portion 40 is formed to be flexible. Any configuration may be used to provide the flexibility of the protective tubular portion 40. Here, the protective tubular portion 40 is formed in a bellows shape and is flexible.

[0058] The vehicle body mounting portion 42 is provided at the other end of the protective tube portion 40. Here, the vehicle body mounting portion 42 is provided so as to be able to be engaged with a through hole formed in the vehicle body 80.

[0059] The inner member 44 is formed in a flat cylindrical shape. The inner member 44 includes a first part 45 and a second part 46. The first part 45 and the second part 46 are molded separately. The first part 45 and the second part 46 are combined after molding. In the closed state, the first part 45 is located closer to the vehicle body 80 than the second part 46, and the second part 46 is located closer to the door panel 12 than the first part 45.

[0060] The first component 45 has a flat plate portion 45a and a peripheral wall portion 45b. The peripheral wall portion 45b is formed on the periphery of the flat plate portion 45a. One end of the flat plate portion 45a is semicircular, and the portion from the middle to the other end is rectangular. The flat plate portion 45a is also curved midway from the middle to the other end so that its planes intersect. The peripheral wall portion 45b is formed to protrude from one main surface of the flat plate portion 45a. The peripheral wall portion 45b is formed on the flat plate portion 45a except for the other end. One opening of the inner member 44 is formed at one end of the flat plate portion 45a. The one opening of the inner member 44 is formed at a position corresponding to one opening of the wire accommodating portion 24.

[0061] The second component 46 has a flat plate portion 46a, a side wall portion 46b, and a peripheral wall portion 46c. The side wall portion 46b is formed around the periphery of the flat plate portion 46a, and the peripheral wall portion 46c is formed around the periphery of the side wall portion 46b. The flat plate portion 46a is formed in a shape corresponding to the flat plate portion 45a. The flat plate portion 46a is formed smaller than the flat plate portion 45a. The flat plate portion 46a and the flat plate portion 45a are parallel to each other with a gap between them. The wiring member 60 is housed between the flat plate portion 46a and the flat plate portion 45a. The side wall portion 46b extends obliquely so as to intersect with the flat plate portion 46a. The peripheral wall portion 46c is formed to protrude from one main surface of the side wall portion 46b. The side wall portion 46b and the peripheral wall portion 46c are formed on the flat plate portion 46a excluding the other end portion. Here, the periphery of the second component 46 is surrounded by the peripheral wall portion 45b of the first component 45. The other opening of the inner component 44 is defined between the first component 45 and the second component 46 at the other end of the inner component 44.

[0062] With respect to the base portion 23, the first part 45 faces the vehicle body side part 27, and the second part 46 faces the door side part 28. A protrusion 47 is formed on the outer surface of each of the first part 45 and the second part 46. The protrusion 47 of the first part 45 fits into the fitting hole 30 of the vehicle body side part 27. The protrusion 47 of the second part 46 fits into the fitting hole 30 of the door side part 28. For example, the protrusion 47 may be formed slightly larger than the fitting hole 30 and press-fit into the fitting hole 30.

[0063] <Weatherstrip> As shown in FIG. 8 , the weatherstrip 50 has a tubular portion 53 and an attachment portion 54. The tubular portion 53 is sandwiched between the door panel 12 and the vehicle body 80 in the closed state, elastically deforms, and is in close contact with the vehicle body 80. The attachment portion 54 is attached to the door panel 12. The first end 51 of the weatherstrip 50 is fitted into the first tubular portion 32, and the second end 52 is fitted into the second tubular portion 33. The portion of the weatherstrip 50 extending from the first end 51 to the outside of the grommet 20 and the portion extending from the second end 52 to the outside of the grommet 20 are attached to the door panel 12 using the attachment portion 54. For example, the attachment portion 54 is formed in a plate shape and attached to the side panel portion 16 using a clip or the like. Alternatively, the attachment portion 54 is fitted into a recess in the door panel 12, for example. The weatherstrip 50 is a molded product made of an elastic material such as an elastomer. The weatherstrip 50 is formed, for example, from a long, linear extrusion-molded member that is cut to the required length. In this case, the weatherstrip 50 has a continuous, uniform cross section.

[0064] The weatherstrip 50 surrounds the periphery of the door 10. The length of the weatherstrip 50 is slightly shorter than the length of the periphery of the door panel 12. Therefore, there is an interrupted section of the weatherstrip 50 between the first end 51 and the second end 52 of the weatherstrip 50. A weatherstrip replacement portion 34 is provided in the grommet 20 in the interrupted section of the weatherstrip 50. For example, the length of the interrupted section of the weatherstrip 50 is longer than the length of the first end 51 of the weatherstrip 50 that is inserted into the first tubular portion 32.

[0065] As shown in FIG. 8 , with the first end 51 fitted into the first tubular portion 32, the attachment portion 54 of the weatherstrip 50 protrudes further toward the door 10 than the vehicle body portion 27 of the extension portion 25. Also, as shown in FIG. 7 , the inner member 44 is housed between the vehicle body portion 27 and the door side portion 28 in the portion where the weatherstrip replacement portion 34 is provided. As a result, when the first end 51 of the weatherstrip 50 is inserted into the first tubular portion 32, if it is inserted too far, the tip of the first end 51 (here, the tip of the attachment portion 54) comes into contact with the inner member 44. This prevents the first end 51 from being inserted further into the first tubular portion 32. The same applies when the second end 52 is inserted into the second tubular portion 33.

[0066] <Wiring components> An intermediate portion of the wiring member 60 is passed through the grommet 20. The portion of the wiring member 60 that is passed through the protective tube portion 40 is bundled so that the cross-sectional shape of the multiple electric wires 62 is as close to circular as possible. This allows the portion of the wiring member 60 that is passed through the protective tube portion 40 to follow the bending of the protective tube portion 40. The portion of the wiring member 60 that is housed in the inner member 44 is flattened, with the multiple electric wires 62 lined up in one direction (here, the vertical direction). The shape of the wiring member 60 deforms from a circular shape to a flattened shape near the connection portion between the protective tube portion 40 and the inner member 44.

[0067] The wiring member 60 passes through the inside of the grommet 20 so as to overlap the weatherstrip substitute portion 34. In the front view of FIG. 3, the wiring member 60 inside the base portion 23 is located between the first end 51 and the second end 52 of the weatherstrip 50.

[0068] The grommet 20 with the weatherstrip 50 assembled therein constitutes a door component. This door component may be transported to a door assembly factory (vehicle assembly factory) and assembled to the door panel 12. A wiring member 60 may be assembled in the door component. The wiring member 60 is passed through the grommet 20 to form a wiring module. This wiring module and the weatherstrip 50 may be transported separately to the door assembly factory (vehicle assembly factory) and assembled to the door panel 12.

[0069] <Effects of the First Embodiment> With the grommet 20 configured as described above and the door component or wiring module including the same, the first end 51 of the weatherstrip 50 is fitted into the first tubular portion 32, and the second end 52 is fitted into the second tubular portion 33. This allows the end of the weatherstrip 50 that is first assembled to the door panel 12 to be fitted into the grommet 20 that is later assembled to the door panel 12, or the end of the weatherstrip 50 that is later assembled to the door panel 12 to be fitted into the grommet 20 that is first assembled to the door panel 12, or both can be assembled to the door panel 12 with the end of the weatherstrip 50 fitted into the grommet 20. This improves the ease of assembling door components to the door panel 12.

[0070] Additionally, the grommet 20 is provided with a lip 37 that locally crushes a portion of the first end 51 of the weatherstrip 50 in the closed state. This improves the sealing performance between the grommet 20 and the weatherstrip 50.

[0071] In addition, the flange 38 is in close contact with the outer surface of the collapsed weatherstrip 50 in the closed state, thereby improving the sealing performance between the grommet 20 and the weatherstrip 50.

[0072] Additionally, the grommet 20 is provided with a weatherstrip substitute 34, which allows the weatherstrip 50 to be shortened. The weatherstrip substitute 34 has a body-facing convex portion 35 and a door-facing convex portion 36. In the closed state, the body-facing convex portion 35 and the door-facing convex portion 36 are collapsed, thereby improving the watertightness of the weatherstrip substitute 34.

[0073] Additionally, the wiring member 60 passes through the inside of the grommet 20 so as to overlap the weatherstrip substitute portion 34. This prevents the wiring member 60 from being involved in the collapse of the weatherstrip 50, stabilizing the way the weatherstrip 50 collapses.

[0074] Furthermore, the weatherstrip 50 is formed in one continuous piece from the first end 51 to the second end 52 so that it can surround the periphery of the door panel 12. As a result, even if the weatherstrip 50 is in a ring shape that surrounds the periphery of the door panel 12, the linear weatherstrip 50 can be bent and used as is, eliminating the need for an endless ring-shaped weatherstrip 50. When the weatherstrip 50 is formed into an endless ring, it is usually cut after extrusion molding and one end of a long weatherstrip is joined to the other end by bonding or fusing. In contrast, the weatherstrip 50 of this example can be used in its long linear form on one side, eliminating the need for the process of forming the weatherstrip 50 into an endless ring.

[0075] [Embodiment 2] A door component, a grommet, and a wiring module according to a second embodiment will be described. Fig. 12 is a perspective view showing the door component according to the second embodiment. Fig. 13 is an exploded rear view showing the door component according to the second embodiment. Fig. 14 is a cross-sectional view taken along line XIV-XIV in Fig. 13. Fig. 15 is a cross-sectional view taken along line XV-XV in Fig. 13. In the description of this embodiment, components similar to those described so far will be assigned the same reference numerals, and description thereof will be omitted.

[0076] In the door component according to the second embodiment, the shape of the outer member 121 in the grommet 120 is different from the shape of the outer member 21 in the grommet 20. In the outer member 21, the base portion 23 in the door mounting portion 22 is formed so that two plates overlap each other, and the joint between the two plates serves as a hinge portion 26 that can be opened and closed. In contrast, in the outer member 121, the base portion 123 in the door mounting portion 122 is formed as a single plate and is not designed to be opened or closed.

[0077] More specifically, the base portion 123 has a vehicle body side portion 27, similar to the base portion 23. The door side portion 28 that was provided on the base portion 23 is omitted from the base portion 123. The weatherstrip substitute portion 134 has a vehicle body-facing protrusion 35, similar to the weatherstrip substitute portion 34. The door-facing protrusion 36 that was provided on the weatherstrip substitute portion 34 is omitted from the weatherstrip substitute portion 134. Therefore, as shown in FIG. 14 , the inner member 144 is exposed on the door panel 12 side relative to the base portion 123.

[0078] Furthermore, since the door-side portion 28 is omitted from the door mounting portion 122, the first tubular portion 132 and the second tubular portion 133 are semi-cylindrical. Therefore, as shown in FIG. 15 , the first end portion 51 of the weatherstrip 50 inserted into the first tubular portion 132 and the second end portion 52 inserted into the second tubular portion 133 each come into contact with the door panel. Note that the term "semi-cylindrical" here refers to a shape that surrounds only a portion of the weatherstrip 50 along the circumferential direction, and does not necessarily have to be half. The first tubular portion 132 and the second tubular portion 133 surround at least half the circumference of the tubular portion 53 of the weatherstrip 50 (here, the entire periphery of the portion of the tubular portion 53 that is not connected to the mounting portion 54). This makes it difficult for the weatherstrip 50 inserted into the first tubular portion 132 and the second tubular portion 133 to slip out of the first tubular portion 132 and the second tubular portion 133 in a direction intersecting the axial direction.

[0079] In the door part of this example, the shape of the inner member 144 in the grommet 120 is also different from the shape of the inner member 44 in the above-described grommet 20. The first part 145 in the inner member 144 further has a rib 48. The inner member 144 is similar to the above-described inner member 44 except for the provision of the rib 48. The inner member 144 with the rib 48 may be applied to the door part of the first embodiment.

[0080] The rib 48 is provided on the periphery of an opening at one end of the flat plate portion 45a (an opening for guiding the wiring member 60 into the protective tube portion 40). The rib 48 fits into the base end of the protective tube portion 40. Furthermore, in the inner member 144, the protrusions 47 fit into the fitting holes 30 in the same manner as the inner member 44. As a result, even if the inner member 144 is exposed relative to the base portion 123, the inner member 144 is less likely to shift position relative to the base portion 123. The rib 48 surrounds part or all of the opening in the flat plate portion 45a along the circumferential direction. Here, the rib 48 is formed in a cylindrical shape that surrounds the entire opening in the flat plate portion 45a along the circumferential direction. The base end of the rib 48 is connected to the flat plate portion 45a. The rib 48 is provided so that it gradually moves away from the flat plate portion 45a and has a smaller diameter from the base end to the tip end. This prevents the wiring member 60 from rubbing strongly against the periphery of the opening in the flat plate portion 45a.

[0081] In the outer member 121, a hinge portion 126 is provided between the base portion 123 and the drawable tube portion 31. The hinge portion 126 extends in a direction perpendicular to the axial direction of the drawable tube portion 31. The provision of the hinge portion 126 makes it easy to bend the base portion 123 and the drawable tube portion 31. After one end of the inner member 144 is inserted into the drawable tube portion 31, the drawable tube portion 31 is bent at the position of the hinge portion 126, and the rib 48 at the other end of the inner member 144 is fitted into the protective tube portion 40.

[0082] The door component of this example further includes a reinforcing plate 70. The reinforcing plate 70 is, for example, a molded part made of resin or metal. The reinforcing plate 70 is disposed on the surface of the door side portion 28. The reinforcing plate 70 surrounds a part of the periphery of the protective tube portion 40. Here, the reinforcing plate 70 is formed into a concave shape in a plan view. The base end of the protective tube portion 40 fits into a recess 71 of the reinforcing plate 70.

[0083] The outer edge of the reinforcing plate 70 is provided away from the first cylindrical portion 132, the second cylindrical portion 133, the body-facing convex portion 35, and the protective cylindrical portion 40. This prevents the reinforcing plate 70 from interfering with the deformation of the first cylindrical portion 132, the second cylindrical portion 133, the body-facing convex portion 35, and the protective cylindrical portion 40.

[0084] Mounting holes 72 are formed in the reinforcing plate 70. The mounting holes 72 are provided at positions corresponding to the mounting holes 29. The reinforcing plate 70 is fixed to the door panel 12 together with the grommet 120 by bolts or the like passed through the mounting holes 29, 72. The reinforcing plate 70 may be applied to the door component of the first embodiment.

[0085] Fig. 16 is a cross-sectional view showing the door part in the door open state. Fig. 17 is a cross-sectional view showing the door part in the door closed state. Figs. 16 and 17 are cross-sectional views taken at the same positions as Figs. 10 and 11.

[0086] In the closed state, the grommet 120 and the weatherstrip 50 are deformed as shown in FIG. 17 . Specifically, in the closed state, the lip 37 provided on the first tubular portion 132 locally crushes a portion of the first end portion 51 in the longitudinal direction, and the lip 37 provided on the second tubular portion 133 locally crushes a portion of the second end portion 52 in the longitudinal direction. The flange 38 is in close contact with the outer surface of the crushed weatherstrip 50. In particular, in this case, the flange 38 is in close contact with the outer surface of the weatherstrip 50 that is crushed and curved by the lip 37 in the closed state. Because the first tubular portion 132 and the second tubular portion 133 are semi-cylindrical, the weatherstrip 50 is in direct contact with the door panel 12 on the side opposite to the side in close contact with the flange 38.

[0087] <Effects of the Second Embodiment> A door component including such a grommet 120 can also achieve the same effects as those of the door component of the first embodiment.

[0088] [Note] Although the grommet 20 has been described as being provided with the lip 37, this is not an essential configuration. The grommet 20 does not necessarily have to be provided with the lip 37.

[0089] Furthermore, although the grommet 20 has been described above as being provided with the flanges 38, 39, this is not an essential configuration. The grommet 20 does not necessarily have to be provided with the flanges 38, 39.

[0090] Furthermore, although the weatherstrip substitute portion 34 has been described above as having a vehicle body-facing protrusion 35 and a door-facing protrusion 36, this is not a required configuration. For example, instead of the vehicle body-facing protrusion 35 or the door-facing protrusion 36, a convex shape may be formed on the vehicle body 80 or the door panel 12 side. Furthermore, although the weatherstrip substitute portion 34 has been described above as being provided on the grommet 20, this is not a required configuration. The grommet 20 does not have to be provided with the weatherstrip substitute portion 34. Furthermore, although the weatherstrip 50 has been described above as having an interrupted section between the first end 51 and the second end 52, this is not a required configuration. The first end 51 and the second end 52 of the weatherstrip 50 may abut against each other inside the grommet 20, for example, and thus there may not be an interrupted section between the first end 51 and the second end 52.

[0091] Furthermore, although it has been described above that the wiring member 60 passes through the inside of the grommet 20 so as to overlap the weatherstrip substitute portion 34, this is not a required configuration. For example, the wiring member 60 may pass through the inside of the grommet 20 so as to overlap the weatherstrip 50. In other words, the first tubular portion 32 or the second tubular portion 33 may be formed so as to overlap the wiring accommodating portion 24.

[0092] Furthermore, although the weatherstrip 50 has been described above as being formed as a single piece that can surround the periphery of the door panel 12 from the first end 51 to the second end 52, this is not a required configuration. The weatherstrip 50 may be discontinued midway from the first end 51 to the second end 52.
