Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a drainage structure for a vehicle door. [Background technology]

[0002] A vehicle door described in Patent Document 1 below has been known. The vehicle door described in Patent Document 1 includes an inner panel and an outer panel that constitute a vehicle body panel, a door trim disposed on the interior side of the inner panel, and a window. The window is configured to be able to move up and down, and when the window is in the raised position (closed position), the lower edge of the window is disposed between the inner panel and the outer panel, with the remaining portion of the window protruding above the vehicle body panel. In addition, a weatherstrip is provided on the upper edge of the outer panel, which is configured to prevent rainwater or the like adhering to the surface of the window facing outside the vehicle cabin from entering between the inner panel and the outer panel.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-236538 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above configuration, if water adheres to the surface of the window facing outside the vehicle cabin, there is a concern that the water will flow down and enter the interior of the vehicle door (more specifically, between the inner panel and the outer panel) through the gap between the window and the weatherstrip. Furthermore, the inner panel generally has an opening (service hole) that penetrates from the interior to the exterior of the vehicle. A worker can insert equipment or tools into the interior of the vehicle door through the opening. If water that has entered the interior of the vehicle door reaches the opening in the inner panel, there is a possibility that the water will enter the vehicle cabin through the opening. For this reason, a sealant (service hole cover) is attached to the inner panel to close the opening. However, providing the sealant increases the number of parts, which is a problem.

[0005] The technology disclosed in this specification was developed based on the above circumstances, and aims to provide a drainage structure for a vehicle door that can prevent water adhering to the outer surface of the window from entering the vehicle cabin. [Means for solving the problem]

[0006] As a means for solving the above problem, the drainage structure for a vehicle door disclosed in this specification comprises an extension member provided on the exterior surface of the vehicle cabin of a window that is arranged to be able to rise and fall relative to a plate-shaped panel member that constitutes the vehicle door, and extending in a direction intersecting the raising and lowering direction of the window, and a flexible tubular member that extends downward from the extension member, wherein the tubular member is arranged on the exterior side of the vehicle cabin relative to the panel member, the extension member has a groove portion that opens upward and extends along the extension direction of the extension member, the upper end of the tubular member is connected to a through hole formed through a wall portion that constitutes the inner surface of the groove portion, and the groove portion extends in a downwardly sloping manner as it approaches the location of the through hole in the extension member.

[0007] According to the above configuration, water adhering to the exterior surface of the window can be received by the extension member. The water received by the extension member flows through the groove of the extension member to the upper end of the pipe member and then guided downward through the interior of the pipe member. This prevents water from adhering to the surface of the panel member at a location higher than the lower end of the pipe member, thereby preventing water adhering to the panel member from entering the vehicle cabin. Furthermore, because the pipe member is flexible, it can deform in response to the movement of the window, preventing it from interfering with the movement of the window.

[0008] The lower end of the pipe member may be disposed opposite the panel-side through-hole formed in the lower end of the panel member. With this configuration, water inside the pipe member can be drained below the vehicle door through the panel-side through-hole.

[0009] Furthermore, the panel member may have an opening formed therethrough in a position higher than the lower end of the pipe member, the opening extending in a direction from the interior to the exterior of the vehicle, and wiring may be inserted through the opening without a sealant between the opening edge and the opening. The pipe member can guide water to a position lower than the opening. This prevents water from entering the vehicle cabin through the opening without the need for a sealant (such as a service hole cover) to close the opening. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a drainage structure for a vehicle door that can prevent water adhering to the surface of the window facing outside the vehicle compartment from entering the vehicle compartment. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] <Embodiment 1> A first embodiment will be described with reference to Fig. 1 to Fig. 7. In this embodiment, a drainage structure for a vehicle door 10 is exemplified as a drainage structure for a vehicle door. The vehicle door 10 is a side door provided on a vehicle, and includes an outer panel 11, an inner panel 20, a door trim 30, and a window 40, as shown in Figs. 1 and 2.

[0013] The outer panel 11 is a panel that constitutes the exterior of the vehicle and is made of, for example, a steel plate. The inner panel 20 is made of, for example, a steel plate and is attached to the outer panel 11 from the inside of the vehicle compartment (the left side in FIG. 1).

[0014] As shown in FIG. 1, the door trim 30 is attached to the inner panel 20 (a plate-shaped panel member constituting a vehicle door) in a manner that covers the inner panel 20 from the inside of the vehicle compartment, and constitutes the interior-facing surface of the vehicle door 10. As shown in FIG. 3, the door trim 30 includes a plate-shaped trim board 31 and an inside handle 32. The trim board 31 is divided into multiple board members (e.g., an upper board 31A, a middle board 31B, and a lower board 31C), but is not limited to this. The inside handle 32 is housed in, for example, a mounting hole 33 formed in the middle board 31B. Furthermore, as shown in FIG. 4, a door lock device 21 for locking and unlocking the vehicle door 10 is provided on the exterior surface of the inner panel 20.

[0015] The inside handle 32 is connected to the door lock device 21 by a wire 23 (wiring). This allows an occupant to unlock the vehicle door 10 by operating the inside handle 32. An opening 24 (service hole) for inserting the wire 23 is formed in the inner panel 20. The opening 24 penetrates in a direction from the interior to the exterior of the vehicle (inside and outside the vehicle). In other words, the opening 24 is open toward the interior of the vehicle and communicates with an internal space S1 (see FIG. 1) formed between the inner panel 20 and the outer panel 11. In this embodiment, as shown in FIG. 4, the wire 23 is inserted into the opening 24 without any sealing material between the opening edge of the opening 24 and the opening 24.

[0016] The window 40 is a plate made of resin glass (for example, acrylic resin) and has optical transparency. The window 40 is provided so as to be movable up and down relative to the inner panel 20 via a lifting device (not shown). When the window 40 is closed (when the window 40 is raised), as shown in FIG. 2 , the lower part of the window 40 is disposed between the outer panel 11 and the inner panel 20, and the remaining part is disposed so as to protrude upward from between the outer panel 11 and the inner panel 20.

[0017] As shown in FIG. 1 , a weatherstrip 25 is attached to the upper end of the trim board 31 (the upper end of the upper board 31A). The upper end of the trim board 31 curves upward toward the outside of the vehicle cabin and is disposed so as to cover the inner panel 20 from above. A weatherstrip 12 is attached to the upper end of the outer panel 11. The weatherstrip 25 is interposed between the trim board 31 and the window 40, and is configured so that its end on the outside of the vehicle cabin abuts against the window 40. The weatherstrip 12 is interposed between the outer panel 11 and the window 40, and is configured so that its end on the inside of the vehicle cabin abuts against the window 40.

[0018] As shown in Fig. 4, the drainage structure of the vehicle door 10 of this embodiment includes an extension member 50 provided on the surface of the window 40 facing outside the passenger compartment, and a flexible tubular member 70 extending downward from the extension member 50. The extension member 50 extends in the front-to-rear direction of the vehicle (a direction intersecting with the direction in which the window is raised and lowered). The weatherstrip 12 and the extension member 50 extend along the upper end of the inner panel 20. When the window 40 is closed (see Fig. 2), the extension member 50 is disposed below the weatherstrip 12 and parallel to it.

[0019] As shown in Fig. 4, the extension member 50 includes a first extension portion 51 that is long in the vehicle front-rear direction, a second extension portion 52 that is also long in the vehicle front-rear direction, and a connecting portion 53 (an intermediate portion in the extending direction) that connects the first extension portion 51 and the second extension portion 52. The second extension portion 52 is disposed on the vehicle front side (the right side in Fig. 4) of the first extension portion 51. As shown in Fig. 6, the connecting portion 53 bulges outward from the vehicle compartment relative to the first extension portion 51 and the second extension portion 52, and has a generally box-like shape that is open upward.

[0020] The extension member 50 is made of the same material as the window 40 and is formed integrally with the window 40, but may be formed of a separate member. The extension member 50 has a groove 60 that opens upward toward the interior of the vehicle and extends along the extension direction of the extension member 50. The groove 60 only needs to open upward, and may also open only upward.

[0021] 6, the groove 60 includes a first extension portion 61 formed in the first extension portion 51, a second extension portion 62 formed in the second extension portion 52, and a connecting portion 63 formed in the connecting portion 53 and connecting the first extension portion 61 and the second extension portion 62. The first extension portion 61 extends along the extension direction of the first extension portion 51, and the second extension portion 62 extends along the extension direction of the second extension portion 52. The groove width (length in the interior and exterior directions of the vehicle) and depth of the connecting portion 63 are set to be larger than those of the first extension portion 61 and the second extension portion 62.

[0022] As shown in Fig. 4, the pipe member 70 is disposed on the outer side of the vehicle cabin (outside the vehicle compartment) with respect to the inner panel 20. As shown in Fig. 2, the pipe member 70 includes a flexible hose 71 and a cylindrical portion 72 connected to the upper end of the hose 71. The lower end of the cylindrical portion 72 is inserted into the upper end of the hose 71. This allows communication between the internal space S2 of the cylindrical portion 72 and the internal space S3 of the hose 71.

[0023] The upper end of the cylindrical portion 72 (the upper end of the pipe member) is inserted into a through-hole 55 formed through the bottom wall portion 54 (the wall portion forming the inner surface of the groove portion) that constitutes the connecting portion 53. As a result, the upper end of the cylindrical portion 72 is connected to the through-hole 55, and the connecting portion 63 (and therefore the groove portion 60) and the internal space S2 of the cylindrical portion 72 are in communication with each other. The upper end of the cylindrical portion 72 is provided with a locking portion 75 that locks onto the upper surface of the bottom wall portion 54.

[0024] As shown in Fig. 5, the extension member 50 has a curved shape such that the connecting portion 53 (a part in the extension direction) is located at the lowest position. In other words, as shown in Fig. 7, the groove portion 60 extends in a manner that slopes downward as it approaches the connecting portion 53 (the portion where the through hole 55 is formed in the extension member 50, and the portion where the extension member 50 is connected to the pipe member 70). More specifically, the first extension portion 61 and the second extension portion 62 that constitute the groove portion 60 each extend in a manner that slopes downward as it approaches the connecting portion 53 of the extension member 50. This allows water in the first extension portion 61 and the second extension portion 62 to flow toward the connecting portion 53.

[0025] 4, a plurality of panel-side through holes 26 are formed in the lower end of the inner panel 20 along the vehicle front-rear direction. The panel-side through holes 26 are formed to penetrate the inner panel 20 in the interior-exterior direction of the vehicle. This allows water inside the vehicle door 10 to be drained below the vehicle door 10 through the panel-side through holes 26.

[0026] A lower end 74 of the hose 71 (a lower end of the tubular member) is disposed opposite the panel-side through-hole 26 that is disposed in the middle of the plurality of panel-side through-holes 26. The hose 71 is fixed to the inner panel 20 near the lower end 74 by a fixing member 73 (adhesive tape, a clip, or the like). The opening 24 described above is formed in the inner panel 20 at a position higher than the lower end 74 of the hose 71.

[0027] Next, the effects of this embodiment will be described. According to the above-described configuration, water adhering to the exterior surface 40A (see FIG. 1) of the window 40 can be received by the extension member 50. The water received by the extension member 50 flows through the groove 60 of the extension member 50 to the upper end of the pipe member 70, and then passes through the interior of the pipe member 70 (the interior of the cylindrical portion 72 and the hose 71) and is guided downward (more specifically, to the panel-side through-hole 26). This prevents water from adhering to a portion of the surface (exterior surface) of the inner panel 20 that is higher than the lower end 74 of the pipe member 70, thereby preventing water adhering to the inner panel 20 from entering the interior of the vehicle. Furthermore, because the pipe member 70 is flexible, it can deform in response to the movement of the window 40, as shown in FIG. 5, preventing the movement of the window 40 from being impeded.

[0028] In this embodiment, as shown in FIG. 4, the length of the hose 71 is set so that it reaches from the connecting portion 53 to the panel-side through-hole 26 when the window 40 is closed, and as shown in FIG. 5, the hose 71 bends as the window 40 descends, thereby allowing the window 40 to descend.

[0029] Furthermore, the lower end 74 of the pipe member 70 is disposed so as to face the panel-side through-hole 26 formed in the lower end of the inner panel 20. With this configuration, water inside the pipe member 70 can be drained below the vehicle door 10 (and ultimately to the outside of the vehicle) through the panel-side through-hole 26.

[0030] In addition, an opening 24 that penetrates from the inside to the outside of the vehicle cabin is formed in the inner panel 20 at a location higher than the lower end 74 of the tubular member 70, and a wire 23 is inserted into the opening 24 without any sealing material between it and the opening edge of the opening 24.

[0031] The pipe member 70 can guide water to a position lower than the opening 24. This makes it possible to prevent water from entering the vehicle interior through the opening 24 without providing a sealing material (such as a service hole cover) to close the opening 24.

[0032] <Embodiment 2> A second embodiment will be described with reference to Fig. 8. The same parts as those in the above embodiment are assigned the same reference numerals, and duplicated descriptions will be omitted. In a vehicle door 110 of this embodiment, as shown in Fig. 8, a hose 171 provided on a pipe member 170 has a bellows portion 172. As a result, the bellows portion 172 expands and contracts in response to the rise and fall of the window 40, thereby preventing the rise and fall of the window 40 from being impeded.
