Description

[Technical Field]

[0001] The present invention relates to a vehicle door. [Background technology]

[0002] Conventionally, vehicle doors are mainly known to be configured with a door panel made of a metal outer panel and inner panel that form the exterior surface of the door, and a resin trim that forms the interior surface of the door. On the other hand, as disclosed in Patent Document 1 below, for example, a configuration is also known in which the inner panel is made of synthetic resin, and various functional parts are attached to the inner panel before it is assembled to the outer panel, with the aim of reducing the number of assembly steps and reducing manufacturing costs. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-318532 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional vehicle doors, such as the vehicle door described in Patent Document 1, are generally configured with three plate-like members overlapping in a vehicle interior / exterior direction. Because conventional vehicle doors require a large number of parts, which increases the manufacturing process and manufacturing costs, in recent years, vehicle doors configured with two plate-like members have been considered. For example, to prevent water from entering the vehicle cabin or to create an enclosed space inside the vehicle door (to activate an air pressure sensor used to deploy an airbag), the vehicle door described in Patent Document 1 ensures sealing between the outer panel and the inner panel, while conventional vehicle doors ensure sealing between the inner panel and the service hole cover. In contrast, when a vehicle door is configured with two plate-like members, sealing must be ensured between the panel that constitutes the interior design surface, specifically, between two or more members that constitute the interior panel.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a reliable seal in a panel that constitutes the interior design surface of a vehicle door. [Means for solving the problem]

[0006] In order to solve the above problems, the vehicle door disclosed in the present application has the following structure. (1) A first panel that constitutes the exterior design surface; a second panel attached to the interior side of the first panel so as to face the interior side and constitute a design surface on the interior side; The second panel is made up of two or more panel members each having a design surface portion that forms the interior design surface, and is configured such that a portion of a second panel member, which is another of the panel members, overlaps from the interior side with a peripheral portion that is a portion formed outside the design surface portion of a first panel member, which is one of the panel members; The second panel member has an outdoor side forming portion formed on the outdoor side of the design surface portion, A vehicle door comprising a fastening member that fastens the exterior forming portion and a part of the peripheral edge portion from the exterior side.

[0007] The vehicle door disclosed in the present application is based on a vehicle door generally composed of two panels, a first panel and a second panel. The second panel, which constitutes the interior design surface, is configured by assembling two or more panel members, each of which has a portion of the interior design surface. A vehicle door with such a configuration must ensure a seal between the two or more panel members. The vehicle door disclosed in the present application can be configured, for example, in a manufacturing process by assembling the second panel, attaching functional components of the vehicle door to the second panel, and finally attaching the first panel to the second panel to complete the vehicle door. Whether the seal of the second panel is properly secured may be determined by visual inspection by a worker or by a captured image. The vehicle door disclosed in the present application has fastening members provided on the exterior side of the second panel. By checking the fastening state of the fastening members, it is possible to reliably ensure a seal between the panel members constituting the second panel.

[0008] In the vehicle door disclosed herein, the shape of the exterior forming portion is not particularly limited. For example, the exterior forming portion may be a generally box-shaped portion protruding from the rear surface of the decorative surface portion, with a base portion at its exterior end contacting a portion of the peripheral edge. Alternatively, the second panel member may be shaped such that the outer edge of the decorative surface portion is curved outward and folded inward, with the folded portion serving as the exterior forming portion.

[0009] The vehicle door disclosed in the present application is not limited to a configuration in which the exterior forming portion of the second panel member forming the interior design surface is located on the interior side of a portion of the peripheral edge, but may also be configured so that the exterior forming portion is located on the exterior side of a portion of the peripheral edge, as will be explained later.

[0010] The vehicle door having the above-described structure can be configured in the following various ways.

[0011] (2) A through hole is formed in a part of the outdoor forming portion and the peripheral edge portion, The fastening member comprises a shaft having a claw portion formed at the tip and a head having a knob portion that can be gripped by an operator's fingers, and when the shaft is inserted into the through hole from the exterior side and rotated around its axis, the claw portion hooks onto the edge of the through hole, fastening the exterior forming portion and a part of the peripheral edge portion together.

[0012] In this vehicle door, the fastening member is limited to a so-called turn clip, and it is easy to determine whether the turn clip is securely fastened by visually checking or by checking an image of the direction in which the knob extends.

[0013] (3) The second panel member has a shape in which the upper end of the design surface portion extends toward the outside of the room, The exterior forming portion is formed by extending downward from the upper end of the design surface portion of the second panel member, The vehicle door according to item (1) or (2), wherein the fastening member fastens the exterior-side forming portion and the portion of the peripheral edge portion from the exterior side of the exterior-side forming portion, with a portion of the peripheral edge portion inserted between the decorative surface portion of the second panel member and the exterior-side forming portion.

[0014] In the manufacturing process of a vehicle door having this configuration, the second panel member can be held to the first panel member by hooking the exterior forming portion onto the peripheral edge portion, which facilitates wiring of the functional components and allows the first and second panel members to be assembled efficiently and reliably, since the fastening members can be fastened after the functional components have been installed.

[0015] (4) The first panel member is made of aluminum die-cast, has a frame shape including the outer peripheral portion of the second panel, and has an opening penetrating from the inside to the outside of the vehicle. The vehicle door according to any one of items (1) to (3), wherein the second panel member covers the opening of the first panel member.

[0016] The vehicle door of this configuration has a novel design in which the first panel member is made of metal. The aluminum die-cast first panel member has a relatively high degree of freedom in molding. For example, when the exterior forming portion is configured to be inserted into the rear side of the peripheral edge portion, it is easy to mold slits for inserting the exterior forming portion. [Effects of the Invention]

[0017] According to the present invention, a panel that constitutes the interior design surface of a vehicle door can be reliably sealed. [Brief explanation of the drawings]

[0019] <Overall structure of the side door> The vehicle door according to the embodiment of the present invention is a front side door of an automobile (vehicle) as a vehicle. The overall configuration of the side door 10 according to the present embodiment will be described with reference to Fig. 1 to Fig. 4. In each drawing, the directions indicated by the arrows are: FR indicates the front of the vehicle, RR indicates the rear of the vehicle, IN indicates the interior direction (inside in the vehicle width direction), and OUT indicates the exterior direction (outside in the vehicle width direction).

[0020] As shown in FIG. 1 , the side door 10 of this embodiment is provided with a door pocket 11 and an armrest 12 as an elbow rest for a passenger on its interior side. Although not shown, the armrest 12 is also provided with an inside handle for opening and closing the side door 10, a pull handle that the passenger can place their hand on (grasp) to open or close the side door 10, and a switch base equipped with operation switches for opening and closing the window and locking and unlocking the side door 10. The side door 10 is also provided with a side mirror 16 on its exterior side. The side door 10 is also provided with a window device 17 that can be raised and lowered, and a locking device 18 that locks and unlocks the side door 10 relative to the vehicle body. The side door 10 of this embodiment is attached to the vehicle body at its front end via a hinge mechanism 19, allowing the side door 10 to swing open and close.

[0021] As shown in Fig. 2, the side door 10 is configured by assembling two panels, a first panel 20 and a second panel 22. The first panel 20 is the outermost panel of the automobile that constitutes the exterior of the automobile and is made of steel plate. The second panel 22 also serves as an interior member, that is, a panel that has a portion that constitutes the interior appearance (interior design surface) of the automobile. The side door 10 is configured such that the first panel 20 and the second panel 22 face each other, with no other panels interposed between them.

[0022] In this embodiment, the first panel 20 is made of a steel plate, but it may be made of other metals or resin. Examples of resins that can be used for the first panel 20 include fiber-reinforced resins (thermosetting resins such as unsaturated polyester, epoxy resin, polyamide resin, phenolic resin, etc., blended with glass fiber, carbon fiber, aramid fiber, polyethylene fiber, etc.), as well as polyacetal resin, polyamide resin, polycarbonate resin, polyimide resin, and ultra-high molecular weight polyolefin (polyethylene) resin. As will be described in detail later, most of the components of the side door 10 are attached to the second panel 22, and no components of the side door 10 are attached to the first panel 20.

[0023] As shown in Fig. 3, the second panel 22 is broadly composed of two panel members 24, 26. The panel member 24 is generally frame-shaped and includes the portion near the outer periphery of the second panel 22, and functions as a base member (hereinafter, may be referred to as "base member 24") to which the other panel member 26 is attached and various functional parts are attached. In this embodiment, the panel member 26 is made of resin, while the base member 24 is made of aluminum alloy and is aluminum die-cast. Note that examples of resins used for the second panel 22 (panel members 24, 26) include, in addition to polypropylene resin, polyethylene resin, polystyrene resin, polyester resin, and resins obtained by blending these resins with natural fibers.

[0024] The base member 24 also includes a main body 30 whose plate surface faces the interior and exterior of the vehicle, and protruding portions 32 that protrude from the front, bottom, and rear ends of the main body 30. The main body 30 has an opening 30a, giving it a generally rectangular frame shape. However, as shown in FIGS. 1 to 3, the front portion 30b of the main body 30 is exposed to the interior and forms the interior design surface. On the other hand, this front portion 30b is not overlapped by any other panel member on the exterior side of the vehicle and directly faces the first panel 20.

[0025] The front protruding portion 32a of the base member 24, which is a portion of the protruding portion 32 that protrudes forward from the front end of the main body 30, is attached to the vehicle body via the hinge mechanism 19. The hinge mechanism 19 requires increased assembly strength because forces related to opening and closing the door are concentrated therein. In this embodiment, the base member 24 is a member having an interior design surface, but is made of die-cast aluminum, so the side door 10 is firmly supported by the hinge mechanism 19. As described above, the side door 10 of this embodiment is configured such that, of the first panel 20 and the second panel 22, only the second panel 22 is attached to the vehicle body via the hinge mechanism 19. As described above, the base member 24 is die-cast aluminum, which makes it easier to ensure rigidity compared to a resin-made base member. Furthermore, because the base member 24 is die-cast aluminum, its thickness can be easily varied from position to position, thereby easily varying its rigidity from position to position. Therefore, the front protruding portion 32a is thicker than the main body portion 30, thereby increasing the rigidity.

[0026] The base member 24 also has an upward extension 34 extending upward on the front side. This upward extension 34 is a mounting seat for attaching the side mirror 16, and the side mirror 16 is fixed by a fastener while extending outward from the vehicle. A cover member 35 is attached to the interior side of the upward extension 34 to hide the fastener. In other words, the side mirror 16 is attached to the second panel 22.

[0027] As described above, the panel member 26 is made of resin and is attached to the interior side of the base member 24 so as to cover the opening 30a of the base member 24. In other words, almost the entire panel member 26 constitutes the interior design surface. This panel member 26 does not cover the entire interior side of the door panel like the door trim of a conventional side door, but is similar to that door trim and will be referred to as the trim member 26 in the following description. As shown in FIG. 2 , an armrest member 36 that forms the armrest 12 is attached to the trim member 26, and a pocket board member 37 that forms part of the inner surface of the door pocket 11 is also attached to the trim member 26. The peripheral edge of the trim member 26 overlaps the interior side of the base member 24 (the opening edge 30c of the opening 30a), but the majority of the trim member 26 directly faces the first panel 20 without being overlapped by any other panel member on the exterior side. Incidentally, the pocket board member 37 together with the trim member 26 can be regarded as one panel member, or it can be regarded as another panel member, and the second panel 22 can be regarded as being made up of three panel members.

[0028] The second panel 22 is provided on its exterior side with three longitudinal reinforcing members 40, 41, and 42 extending in the front-to-rear direction. Specifically, the three reinforcing members 40, 41, and 42 are disposed on the exterior side of the base member 24, spanning the front overhang 32a and rear overhang 32b of the base member 24. The first reinforcing member 40 extends parallel to the upper edge of the main body 30 of the base member 24. The second reinforcing member 41 is disposed below the first reinforcing member 40, along the inner surface of the first panel 20 near the center in the vertical direction (the portion that protrudes most toward the exterior). The third reinforcing member 42 functions as an impact beam to absorb impact from the exterior side during a vehicle side collision, and is disposed at approximately the height of the waist of an occupant seated inside the vehicle.

[0029] A window device 17 is disposed on the exterior side of the second panel 22, on the interior side of the three reinforcing members 40, 41, and 42. The window device 17 includes a plate-shaped window glass 44 and a regulator 45, which is a drive source for raising and lowering the window glass 44. To enable the window glass 44 to be raised and lowered, weather strips (not shown) are provided on the exterior side of the upper edge of the base member 24 and on the upper edge of the first reinforcing member 40 to fill the gap between the window glass 44 and allow the window glass 44 to be raised and lowered. The window glass 44 is slidably interposed between these opposing weather strips. Also, a wiring 46 connecting the regulator 45 to the switch base and a wiring 47 connecting the locking device 18 to the inside handle, as shown in FIG. 3, are held by the second panel 22.

[0030] The first panel 20 is detachably attached to the second panel 22, covering the second panel 22 from the outside, to which various functional components are attached. Specifically, as shown in Fig. 2, a plurality of clip seats 50 are provided at intervals around the periphery of the first panel 20, and a plurality of clips attached to the clip seats 50 can be used to fit the second panel 22, more specifically, into a plurality of mounting seats 51 (see Fig. 4) provided on the exterior side surface of the protruding portion 32 of the base member 24. Also, as shown in Fig. 1, fastening portions 52 are provided at two locations, at the front upper end and the rear upper end of the side door 10, so that the first panel 20 and the second panel 22 can be fastened together with bolts from the passenger compartment side of the second panel 22. Specifically, the first panel 20 has a female threaded portion 52a with a female thread formed therein, as shown in Figure 3, and the second panel 22, more specifically, the upper end of the front protrusion 32a and the upper end of the rear protrusion 32b of the base member 24, has insertion holes 52b for inserting bolts at positions corresponding to the female threaded portion 52a, as shown in Figures 3 and 4.

[0031] The first panel 20 does not have any functional parts of the side door 10 attached thereto, and is configured to be easily detachable from the second panel 22, to which various functional parts are attached. On the other hand, due to the presence of the fastening portion 52, when the side door 10 is locked to the vehicle body, the first panel 20 cannot be detached from the second panel 22 even if multiple clips are released from outside the vehicle compartment, and theft of the first panel 20 can be prevented.

[0032] As described above, in the side door 10 of this embodiment, the second panel 22 is composed of two panel members 24, 26. These panel members 24, 26 constitute the interior design surface (design surface portion) and have a portion that directly faces the first panel 20 without any other panel member overlapping the first panel 20. Therefore, in the side door 10 of this embodiment, many of the portions that form the interior design surface can be configured as a two-layer structure (double structure) of the first panel 20 and the second panel 22, thereby reducing the number of parts required for the entire side door 10. Furthermore, as shown in FIG. 2 , the side door 10 of this embodiment does not have any plate-like members between the first panel 20 and the second panel 22, ensuring a relatively large space and allowing for greater flexibility in the installation of functional components. Therefore, the side door 10 of this embodiment achieves simplified and easy manufacturing processes and reduced manufacturing costs.

[0033] <Mounting structure of panel member in second panel> The side door 10 of this embodiment configured as described above does not have a triple structure extending from the interior to the exterior of the vehicle as in conventional side doors, and the second panel 22 that forms the interior design surface is made up of two panel members 24, 26, each of which has an interior design surface, so that a seal must be secured between the two panel members 24, 26 in order to prevent water from entering the interior and to create an airtight space inside the side door 10 (to activate an air pressure sensor used to deploy an airbag). The side door 10 of this embodiment is characterized by the mounting structure of the two panel members 24, 26 that ensures this seal, and the mounting structure between the base member 24 and the trim member 26 will be described in detail below with reference to Figures 4 to 9.

[0034] The base member 24 has a front portion 30b of the main body 30 as a design surface portion that forms the interior-facing design surface. Hereinafter, the front portion 30b may be referred to as the base-side design surface portion 30b. As shown in FIG. 3 , the base member 24 has an opening 30a and an opening edge (corresponding to a peripheral edge portion) 30c formed on the outer side (rear side) of the base-side design surface portion 30b. The trim member 26 is attached so as to overlap the opening edge 30c on the interior side, thereby closing the opening 30a. In other words, the base member 24 corresponds to the first panel member, and the trim member 26 corresponds to the second panel member. Furthermore, as shown in FIG. 4 , five fastening portions are provided between the base member 24 and the trim member 26 at the portions where the opening edge 30c of the base member 24 and the trim member 26 overlap. These five fastening portions are fastening structures using turn clips 60, which are an example of fastening members, as will be described in detail later.

[0035] First, the fastening structure C1 provided at the lower end on the vehicle rear side will be described. As shown in Fig. 5, the trim member 26 includes a design surface portion 62 facing the interior side, a lower standing wall portion 63 erected from the lower end of the design surface portion 62 toward the exterior side, and a generally box-shaped base portion (exterior-facing portion) 64 protruding toward the exterior side from the exterior surface of the connecting portion between the design surface portion 62 and the lower standing wall portion 63. As shown in Fig. 6, a rectangular through-hole 66 is formed in a seat portion 64a, which is the tip (exterior-facing end) of the base portion 64. Meanwhile, a circular through-hole 67, which is slightly larger than the through-hole 66, is formed in the opening edge 30c of the base member 24 at a position overlapping with the through-hole 66 of the trim member 26 attached to the base member 24.

[0036] As shown in Figures 5 to 7, the turn clip 60 comprises a shaft 70 and a head 72. The shaft 70 has a cylindrical base 70a on the head 72 side and cross-shaped claws 70b on the tip side, with the claws 70b being larger than the base 70a when viewed from the axial direction of the shaft 70, and each tip of the cross shape of the claws 70b protruding radially from the base 70a. The head 72 also has an annular suction cup 72a extending toward the shaft 70 side and a knob 72b extending linearly when viewed from the axial direction of the shaft 70.

[0037] The turn clip 60 is attached from the exterior side of the base member 24. Specifically, the shaft 70 is inserted from the exterior side of the base member 24, first through the through-hole 67 of the base member 24 and then through the through-hole 66 of the trim member 26. At this time, the claws 70b pass through the through-hole 66 by aligning each end of the cross shape with the corners of the square-shaped through-hole 66 of the trim member 26 (indicated by the two-dot chain lines in FIG. 5). After the claws 70b pass through the through-hole 66, they are rotated 45° (indicated by the solid lines in FIGS. 5 and 6). As the suction cups 72a elastically deform, the claws 70b latch onto the edge of the through-hole 66, and the turn clip 60 fastens the opening edge 30c of the base member 24 and the seat portion 64 (specifically, the seat surface portion 64a) of the trim member 26.

[0038] As shown in FIG. 5, a sealant 74 is interposed between the tip of the lower upright wall portion 63 of the trim member 26 and the interior side of the opening edge 30c, and when the turn clip 60 fastens the opening edge 30c of the base member 24 to the base portion 64 of the trim member 26, the sealant 74 is firmly crushed, improving the sealing performance.

[0039] 5, the turn clip 60 is securely fastened when the knob portion 72b extends in the vertical direction. Therefore, by checking the orientation of the knob portion 72b visually or by processing an image captured by an inspection device or the like, it is possible to easily check whether the turn clip 60 is fastened.

[0040] Next, the fastening structure on the upper end side of the trim member 26 will be described with reference to Figures 8 and 9. The fastening structure C2 shown in Figure 8 is provided at a position corresponding to the upper rear end of the side door 10, as shown in Figure 4. The trim member 26 has a design surface portion 62 with a curved portion 62a that curves more toward the exterior as it approaches the upper end, and has a generally plate-shaped extension portion 80 that extends downward from a middle portion of the curved portion 62a. In other words, this extension portion 80 is an exterior-side forming portion that is formed at a position spaced outside from the main body portion 62b of the design surface portion 62 that faces the interior side (left side in the vehicle width direction).

[0041] The curved portion 62a of the trim member 26 described above covers the upper end of the base member 24 (the upper end of the opening edge 30c) from above. When attaching the trim member 26 to the base member 24, the upper end of the opening edge 30c of the base member 24 is inserted between the decorative surface portion 62 of the trim member 26 and the extension portion 80. The extension portion 80 of the trim member 26 overlaps the exterior side of the opening edge 30c of the base member 24, and the extension portion 80 and the opening edge 30c are fastened together with the turn clip 60. That is, in this fastening structure C2, a square through-hole 82 is formed in the opening edge 30c of the base member 24, and a circular through-hole 83 that is slightly larger than the through-hole 82 is formed in the extension portion 80 of the trim member 26, and the extension portion 80 of the trim member 26 is fastened together from the exterior side of the vehicle by the turn clip 60.

[0042] Furthermore, fastening structure C3 shown in FIG. 9 has a configuration similar to fastening structure C2. However, while fastening structure C2 is a portion in which the trim member 26 covers the base member 24 from above, fastening structure C3 is a portion in which the base member 24 is provided in a position covering the opening edge 30c located below the base-side design surface portion 30b. The trim member 26 has a folded portion 90, which is an exterior-facing portion folded downward from the upper end of the design surface portion 62. Meanwhile, the base member 24 has a slit 92 formed between the base-side design surface portion 30b and the opening edge 30c. More specifically, the lower end of the base-side design surface portion 30b is located further exterior than the upper end of the opening edge 30c, and a slit 92 opening upward is formed between the lower end of the base-side design surface portion 30b and the upper end of the opening edge 30c. In fastening structure C3, the folded portion 90 of the trim member 26 can be inserted through this slit 92, so that the folded portion 90 overlaps the exterior side of the opening edge 30c. A rectangular through-hole 94 is formed in the opening edge 30c of the base member 24, and a circular through-hole 95 that is slightly larger than the through-hole 94 is formed in the folded portion 90 of the trim member 26, and the turn clip 60 fastens the folded portion 90 of the trim member 26 from the exterior side. As mentioned above, the base member 24 is made of metal, but because it is aluminum die-cast, there is a relatively high degree of freedom in molding, making it easy to mold a shape with the slit 92 as described above.

[0043] Incidentally, the other fastening structures C4 and C5 have the same configuration as the fastening structure C1, and therefore illustrations and explanations thereof will be omitted.

[0044] With the above-described configuration, in the manufacturing process of the side door 10 of this embodiment, when attaching the trim member 26 to the base member 24, the extension portion 80 of the fastening structure C2 and the folded-back portion 90 of the fastening structure C3 can be hooked onto the base member 24, allowing the trim member 26 to be held on the base member 24 without fastening. For example, the installation work of the window device 17 and the locking device 18, which are the functional components described above, and the routing work of the wires 46, 47 can be easily performed, and after these work steps are completed, the turn clips 60 of the five fastening structures only need to be fastened, so the base member 24 and the trim member 26 can be assembled efficiently and reliably.

[0045] <Other embodiments> The present invention is not limited to the above-described embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art. For example, the following embodiments are also included within the technical scope of the present invention.

[0046] In the present invention, the outdoor forming portion is a portion formed on the outdoor side of the decorative surface portion 62 of the trim member 26, which is the second panel member, and its shape is not particularly limited as long as it has a flat portion that contacts part of the opening edge (peripheral edge portion 30c) of the base member 24, which is the first panel.

[0047] In the above embodiment, the fastening member is the turn clip 60, but it may also be a bolt with a male thread formed thereon.

[0048] In the above embodiment, the second panel 22 includes two panel members each having a design surface portion, but it may include three or more panel members. The shapes of the panel members are not particularly limited, and various shapes can be adopted.

[0049] In the above embodiment, the base member 24, which is the first panel member, is made of die-cast aluminum, but it may also be made of resin.
