Description

[Technical Field]

[0001] The present invention relates to a vehicle door structure, and more particularly to a vehicle door structure provided with a waterproof film that prevents water from entering the vehicle interior and a regulator handle for raising and lowering a window. [Background technology]

[0002] Conventionally, there is known a technology relating to a vehicle door structure equipped with a waterproof film that prevents water from entering the vehicle interior. For example, Patent Document 1 describes a vehicle door equipped with a waterproof film and a manual regulator for raising and lowering the window. The waterproof film of this vehicle door has a perforated slit at the mounting position of the shaft of the manual regulator. Meanwhile, Patent Document 2 describes a vehicle door in which a waterproof film is interposed between the inner panel and the door trim of the vehicle door and the waterproof film is attached to the inner panel with a butyl seal. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 01-109423 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-74964 Summary of the Invention [Problem to be solved by the invention]

[0004] In the vehicle door structure described in Patent Document 1, by providing perforated slits in the waterproof film, water is prevented from entering the vehicle interior from those positions, compared to when a through-hole for passing the regulator shaft of a manual regulator is formed. However, even if the regulator shaft is passed through the slit, it is difficult to completely prevent water from entering, and there is a need for a method for better preventing water from entering.

[0005] The present invention has been made in consideration of such problems, and its purpose is to provide a vehicle door structure that can better prevent water from entering the passenger compartment from the position where the regulator shaft of the manual regulator penetrates the waterproof film. [Means for solving the problem]

[0006] In order to achieve the above object, the vehicle door structure of the present invention comprises a door body including an inner panel covering the inside surface and an outer panel forming the outside surface, a window glass that can move up and down between the inner panel and the outer panel, a waterproof film for waterproofing that is arranged on the passenger compartment side of the inner panel, a sealing member that attaches the waterproof film to the inner panel, and a manual regulator that is attached to a regulator handle and has a regulator shaft that passes through the inner panel and the waterproof film, and raises and lowers the window glass as the regulator shaft rotates, the inner panel having a regulator mounting portion including a through hole through which the regulator shaft is inserted and a service hole for work formed above the through hole, the waterproof film having a shaft insertion portion through which the regulator shaft is inserted at a position corresponding to the through hole, and the sealing member having a seal extension portion that extends between the regulator mounting portion and the service hole above the through hole and the shaft insertion portion.

[0007] With this configuration, even if water flows into the passenger compartment side of the inner panel from the service hole, the seal extension extending between the regulator mounting portion and the service hole blocks the water and prevents it from flowing down into the slit. Therefore, the vehicle door structure according to the embodiment can more effectively prevent water from entering the passenger compartment from the position where the regulator shaft of the manual regulator penetrates the waterproof film.

[0008] Preferably, the seal extension extends while inclining downward in the longitudinal direction of the vehicle. This configuration allows water to be smoothly guided in the longitudinal direction of the vehicle without accumulating on the seal extension.

[0009] Preferably, the regulator mounting portion has a reinforcing portion protruding from the inner panel toward the passenger compartment, and a through hole is formed at a tip of the reinforcing portion on the passenger compartment side, the tip being located closer to the passenger compartment than the seal mounting surface of the inner panel to which the seal extension portion is attached. With this configuration, water flowing down from the seal extension portion can be temporarily received by the upper edge of the reinforcing portion and can be more effectively prevented from flowing into the slit.

[0010] Furthermore, it is preferable that the upper edge of the reinforcing portion includes an inclined surface that extends downward as it moves away from the slit in the vehicle longitudinal direction. With this configuration, water on the upper edge of the reinforcing portion can be smoothly guided away from the slit without accumulating.

[0011] The inner panel preferably has a positioning portion that protrudes toward the passenger compartment and positions the end of the seal extension portion. This configuration allows most of the water that reaches the end of the seal extension portion to flow downward along the surface of the positioning portion, preventing the water from reaching the underside of the seal extension portion. As a result, water can be prevented from flowing from the underside of the seal extension portion into the slit. [Effects of the Invention]

[0012] According to the vehicle door structure of the present invention, it is possible to more effectively prevent water from entering the passenger compartment from the position where the regulator shaft of the manual regulator penetrates the waterproof film. [Brief explanation of the drawings]

[0013] [Figure 1] FIG. 1 is a front view showing an inner panel of a vehicle door structure according to an embodiment. [Figure 2] FIG. 2 is a cross-sectional view of the vehicle door structure taken along line AA in FIG. [Figure 3] FIG. 3 is a front view showing a main part of the vehicle door structure. DETAILED DESCRIPTION OF THE INVENTION

[0014] An embodiment of the present invention will be described below with reference to the drawings. In the following description, the vehicle front-rear direction, vehicle width direction, and up-down direction are expressed based on a vehicle to which the vehicle door structure of the embodiment is applied.

[0015] (Vehicle door structure) Fig. 1 is a front view showing an inner panel of a vehicle door structure according to an embodiment, Fig. 2 is a cross-sectional view of the vehicle door structure taken along line AA in Fig. 1, and Fig. 3 is a front view showing a main part of the vehicle door structure. The vehicle door structure 1 according to the embodiment is applied to a side door of a vehicle (not shown). As shown in Figs. 1 and 2, the vehicle door structure 1 according to the embodiment includes a door body 10, a waterproof film 20, a seal member 30, and a manual regulator 40.

[0016] (Door body) The door body 10 includes an outer panel 12 and an inner panel 14. The outer panel 12 forms the outer surface of the door body 10 opposite the vehicle interior (not shown). The inner panel 14 is disposed on the vehicle interior side of the outer panel 12 and is joined to the outer panel 12. A plurality of service holes 15 for work purposes are formed in the inner panel 14. A door trim (not shown) that forms the inner surface of the door body 10 is joined to the vehicle interior side of the inner panel 14. That is, the inner panel 14 covers the door trim, which forms the inner surface of the door body 10, from the outer panel 12 side (the side opposite the vehicle interior). Furthermore, a window glass 18 that can be moved up and down by a manual regulator 40 (described later) is provided between the outer panel 12 and the inner panel 14.

[0017] (Waterproof film) The waterproof film 20 (hereinafter simply referred to as "film 20") is made of a material containing, for example, a non-biodegradable material or a biodegradable material, and is a waterproof sheet interposed between the inner panel 14 and a door trim (not shown) as shown in FIG. 2. Note that in FIGS. 1 and 3, the film 20 is not shown except for a portion that schematically shows slits 22, which will be described later. The film 20 prevents water from entering the passenger compartment from outside the vehicle through a plurality of service holes 15 formed in the inner panel 14. The film 20 is attached to the passenger compartment side surface of the inner panel 14 with a seal member 30.

[0018] (Sealing material) The seal member 30 is a sealing material such as a butyl seal made primarily of butyl rubber. As shown in Fig. 1, the seal member 30 is provided along the outer edge of the film 20 and attaches the film 20 to the inner panel 14. The seal member 30 may be any material that can attach the film 20 to the inner panel 14 and is waterproof, and may be a tape-like sealant or a sealant formed by application.

[0019] (Manual regulator) The manual regulator 40 is a window glass raising and lowering device that raises and lowers the window glass 18, and as shown in Fig. 2, a regulator shaft 44 (hereinafter simply referred to as "shaft 44") is attached to a regulator handle 42 (hereinafter simply referred to as "handle 42") located inside the vehicle cabin. Note that Fig. 2 only shows the portion of the handle 42 that is attached to the shaft 44. The shaft 44 penetrates the inner panel 14 and the film 20 in the vehicle width direction, and is rotatably held by a regulator main body 46 that is joined to the surface of the inner panel 14 facing the outer panel 12. A link mechanism (not shown) is provided between the regulator main body 46 and the window glass 18, which raises and lowers the window glass 18 in accordance with the rotation of the handle 42 and shaft 44.

[0020] Here, a through hole 52 for inserting the shaft 44 is formed in the inner panel 14. A cross-shaped slit (shaft insertion portion) 22 for inserting the shaft 44 is formed in the film 20 at a position corresponding to the through hole 52 in the inner panel 14 (a position aligned with the through hole 52 in the vehicle width direction). One of the service holes 15 (hereinafter referred to as the "service hole 151") is formed in the inner panel 14 above the through hole 52 and the slit 22. Therefore, as shown by the dashed arrow in FIG. 2 , it is necessary to prevent water dropping downward from the service hole 151 from flowing between the inner panel 14 and the film 20 and entering the vehicle interior through the slit 22. In this embodiment, by forming the slit 22 in the film 20, a gap between the shaft 44 and the film 20 is minimized compared to when a through hole is formed in the same location. However, it is difficult to completely prevent water from entering through the slit 22. The vehicle door structure 1 of this embodiment has the following configuration in order to more effectively prevent water from entering the vehicle interior through the slit 22.

[0021] (Regulator mounting part) The inner panel 14 has a regulator mounting portion 50 for mounting the manual regulator 40. As shown in FIGS. 2 and 3 , the regulator mounting portion 50 includes the through hole 52 and a reinforcing portion 54 formed around the through hole 52. The reinforcing portion 54 extends in the longitudinal direction of the vehicle, sandwiching the through hole 52 and the slit 22, and protrudes upward from a base portion 14a on the passenger compartment side surface of the inner panel 14 toward the passenger compartment. In other words, the through hole 52 is formed at a tip 54a of the reinforcing portion 54 on the passenger compartment side. The tip 54a of the reinforcing portion 54 on the passenger compartment side is located closer to the passenger compartment than a seal mounting surface 142, which will be described later.

[0022] Furthermore, the upper edge 54u of the reinforcing portion 54 includes an inclined surface 56 that extends downward as it moves away from the slit 22 in the vehicle longitudinal direction. More specifically, the upper edge 54u includes an arc-shaped portion 541u that extends in an arc shape around the through-hole 52, and an extension 542u that extends downward from the arc-shaped portion 541u toward the rear in the vehicle longitudinal direction. As a result, the extension 542u extends from the upper end of the arc-shaped portion 541u to form the inclined surface 56.

[0023] (extended seal) 1 to 3, the seal member 30 includes a seal extension 60. The seal extension 60 extends in the vehicle longitudinal direction from a position in the vicinity of the service hole 151 at the portion where the film 20 is attached along the outer edge. In this embodiment, the inner panel 14 is formed with a seal mounting surface 142 that extends along the lower edge 151a of the service hole 151 (see FIG. 3), and the seal extension 60 is attached to this seal mounting surface 142.

[0024] The seal mounting surface 142 protrudes toward the passenger compartment further than the base 14a. However, as described above, the seal mounting surface 142 is located closer to the outer panel 12 than the passenger compartment-side tip 54a of the reinforcing portion 54. Because both the seal mounting surface 142 and the reinforcing portion 54 protrude from the base 14a toward the passenger compartment, a recess 146 recessed toward the outer panel 12 is formed between the seal mounting surface 142 of the inner panel 14 and the upper edge 54u of the reinforcing portion 54.

[0025] The seal mounting surface 142 extends in the vehicle fore-and-aft direction from forward of the service hole 151 to rearward of the through-hole 52 and the slit 22 of the regulator mounting portion 50. More specifically, the seal mounting surface 142 extends to the inclined surface 56 of the upper edge portion 54u of the reinforcing portion 54 (to the middle of the extension portion 542u). In this embodiment, the lower edge 151a of the service hole 151 extends while sloping downward in the vehicle fore-and-aft direction, and the seal mounting surface 142 along the lower edge 151a also extends while sloping downward in the vehicle fore-and-aft direction.

[0026] Furthermore, a positioning portion 144 is formed at the rear end of the seal mounting surface 142 in the vehicle longitudinal direction. The positioning portion 144 is formed continuous with a reinforcing portion 148 that protrudes from the base portion 14a of the inner panel 14 toward the passenger compartment, and protrudes further toward the passenger compartment than the seal mounting surface 142. It is preferable that the positioning portion 144 protrudes further toward the passenger compartment than the seal extension portion 60 attached to the seal mounting surface 142. Note that the positioning portion 144 and the film 20 are not in close contact with each other, and a gap is formed between them.

[0027] Therefore, the seal extension portion 60 attached to the seal mounting surface 142 extends along the lower edge 151a of the service hole 151 and extends between the regulator mounting portion 50 and the service hole 151 so as to cover the upper part of the through-hole 52 and the slit 22. The seal extension portion 60 extends from a position forward of the service hole 151 in the vehicle longitudinal direction. That is, a starting end 62 (see FIG. 3) of the seal extension portion 60 is located forward of the service hole 151 in the vehicle longitudinal direction. Furthermore, a terminal end 64 (see FIG. 3) of the seal extension portion 60 is positioned by the positioning portion 144. That is, the seal extension portion 60 is attached to the seal mounting surface 142 so that the terminal end 64 extends to the positioning portion 144. The positioning portion 144 may serve as a mark for the terminal end 64 when attaching the seal extension portion 60 to the seal mounting surface 142. With the above-described configuration, the seal extension portion 60 extends along the entire lower edge 151a of the service hole 151 and extends up to the inclined surface 56 of the upper edge portion 54u of the reinforcing portion 54 (to the middle of the extension portion 542u). Moreover, the seal extension portion 60 extends from its starting end 62 to its terminal end 64 while sloping downward in the vehicle longitudinal direction.

[0028] (Operation of the embodiment) In the vehicle door structure 1 configured as described above, water that flows into the passenger compartment side of the inner panel 14 through the service hole 151 (see the dashed arrow in FIG. 2) is blocked by the seal extension 60 so as not to flow between the inner panel 14 and the film 20. Of the water blocked by the seal extension 60, some flows toward the outer panel 12 side of the inner panel 14, as shown by the solid arrow in FIG. 2, and some flows along the seal extension 60 toward the rear in the vehicle's fore-and-aft direction, as shown by the hollow arrow in FIG. 3. At this time, because the seal extension 60 slopes downward from the starting end 62 to the ending end 64, the water on the seal extension 60 is smoothly guided toward the rear in the vehicle's fore-and-aft direction without stagnating.

[0029] Water flowing over the seal extension portion 60 flows downward from the end 64. This water flowing downward from the end 64 flows between the inner panel 14 and the film 20. However, because the end 64 of the seal extension portion 60 is located rearward of the slit 22 in the vehicle longitudinal direction, water from the end 64 flows downward to a position away from the slit 22. Furthermore, because the end 64 of the seal extension portion 60 extends to the positioning portion 144 of the inner panel 14, most of the water that has flowed to the end 64 flows downward along the surface of the positioning portion 144. In other words, water is prevented from spreading from the end 64 to the underside of the seal extension portion 60. Therefore, the end 64 and the positioning portion 144 do not necessarily need to abut each other; a small gap may be formed between them that is large enough to prevent water that has flowed to the end 64 from spreading to the underside of the seal extension portion 60.

[0030] Furthermore, water flowing downward from the end 64 of the seal extension 60 is temporarily received by the upper edge 54u of the reinforcement portion 54, which protrudes toward the passenger compartment from the base 14a of the inner panel 14. At this time, as described above, the recess 146 is formed between the seal mounting surface 142 and the upper edge 54u of the reinforcement portion 54, ensuring the length of the upper edge 54u in the vehicle width direction, making it easier for the upper edge 54u to receive water. Water on the upper edge 54u of the reinforcement portion 54 is then smoothly guided away from the slit 22 along the extension 542u, which extends downward as it moves away from the slit 22 in the vehicle front-rear direction, without accumulating.

[0031] Even if some water flows onto the upper edge portion 54u of the reinforcement portion 54 near the slit 22, the water can be temporarily received by the upper edge portion 54u as described above, and the received water does not immediately flow into the slit 22. The received water is guided in a direction away from the slit 22 along the arc-shaped portion 541u and the extension portion 542u. In addition, because the cabin-side tip 54a of the reinforcement portion 54 is located closer to the cabin than the seal mounting surface 142, the received water is more effectively prevented from flowing into the slit 22. Due to the above-mentioned actions, water that flows from the service hole 151 into the cabin side of the inner panel 14 is prevented from entering the cabin side via the slit 22.

[0032] (Effects of the embodiment) As described above, the vehicle door structure 1 according to the embodiment comprises a door body 10 including an inner panel 14 covering the inside surface and an outer panel 12 forming the outside surface, a window glass 18 that can move up and down between the inner panel 14 and the outer panel 12, a waterproof film (waterproof film) 20 arranged on the passenger compartment side of the inner panel 14, a sealing member 30 that attaches the film 20 to the inner panel 14, and a manual regulator 40 that has a shaft (regulator shaft) 44 attached to a handle (regulator handle) 42 and that passes through the inner panel 14 and the film 20, and that raises and lowers the window glass 18 as the shaft 44 rotates. The inner panel 14 has a regulator mounting portion 50 including a through hole 52 through which the shaft 44 is inserted, and a service hole 151 for work formed above the through hole 52, the film 20 has a slit (shaft insertion portion) 22 through which the shaft 44 is inserted at a position corresponding to the through hole 52, and the sealing member 30 has a seal extension portion 60 extending between the regulator mounting portion 50 and the service hole 151 so as to cover the through hole 52 and the upper part of the slit 22.

[0033] With this configuration, even if water flows into the passenger compartment side of the inner panel 14 from the service hole 151, the seal extension 60 extending between the regulator mounting portion 50 and the service hole 151 blocks the water, preventing it from flowing down into the slit 22. Therefore, the vehicle door structure 1 according to the embodiment can more effectively prevent water from entering the passenger compartment from the position where the shaft 44 of the manual regulator 40 penetrates the film 20.

[0034] Furthermore, the seal extension portion 60 extends while inclining downward in the longitudinal direction of the vehicle. With this configuration, water on the seal extension portion 60 can be smoothly guided in the longitudinal direction of the vehicle without accumulating.

[0035] The regulator mounting portion 50 also has a reinforcing portion 54 that protrudes from the inner panel 14 toward the passenger compartment, and a tip 54a of the reinforcing portion 54 on the passenger compartment side has a through-hole 52 formed therein and is located closer to the passenger compartment than the seal mounting surface 142 to which the seal extension portion 60 of the inner panel 14 is attached. With this configuration, water that flows down from the seal extension portion 60 is temporarily received by the upper edge portion 54u of the reinforcing portion 54, and the received water can be more effectively prevented from flowing into the slit 22.

[0036] Additionally, the upper edge 54u of the reinforcing portion 54 includes an inclined surface 56 (arcuate portion 541u and extension portion 542u) that extends downward as it moves away from the slit 22 in the vehicle longitudinal direction. This configuration allows water on the upper edge 54u of the reinforcing portion 54 to be smoothly guided away from the slit 22 without accumulating therein.

[0037] The inner panel 14 also has a positioning portion 144 that protrudes toward the passenger compartment and positions the end 64 of the seal extension portion 60. This configuration allows most of the water that has flowed to the end 64 of the seal extension portion 60 to flow downward along the surface of the positioning portion 144, making it possible to prevent the water from reaching the underside of the seal extension portion 60. As a result, it is possible to prevent water from flowing from the underside of the seal extension portion 60 down into the slit 22.

[0038] (Variation) Although the description of the embodiment is now complete, aspects of the present invention are not limited to this embodiment. For example, in this embodiment, the seal extension portion 60 extends from a position near the service hole 151 in the portion of the seal member 30 that is attached along the outer edge of the film 20. However, the seal extension portion 60 may not be connected to the portion of the seal member 30 that is attached along the outer edge of the film 20. However, it is preferable that the seal extension portion 60 extend in the vehicle longitudinal direction at least from the end portion 58 (the front end of the reinforcing portion 54) that is located below the service hole 151 of the regulator mounting portion 50 to a position beyond the slit 22.

[0039] In addition, in this embodiment, the seal extension portion 60 and the inclined surface 56 (arcuate portion 541u, extension portion 542u) of the reinforcing portion 54 extend downward toward the rear in the vehicle longitudinal direction. However, the seal extension portion 60 and the inclined surface 56 of the reinforcing portion 54 may extend in different directions depending on the positions of the regulator mounting portion 50 and the service hole 151. The inclined surfaces of the seal extension portion 60 and the reinforcing portion 54 may extend downward toward the front in the vehicle longitudinal direction, for example.

[0040] Furthermore, the film 20 may have, instead of the slit 22, a shaft insertion portion such as a through hole through which the shaft 44 can be inserted. [Explanation of symbols]
