[0003]

[0001] The present invention relates to a window structure, a back door, and a moving body of a moving body.

Background Art

[0002] A configuration in which a window portion of a moving body is adhered to an outer panel and an inner panel with an adhesive is known. FIG. 1 is a schematic view showing the appearance of a back door having a window portion, and FIG. 2 is a schematic cross-sectional view taken along the dashed line A-A in FIG. 1 showing a conventional configuration in which the window portion is assembled to an outer panel (lower outer panel) and an inner panel.

[0003] The back door 10 shown in FIGS. 1 and 2 includes an upper outer panel 112 and a lower outer panel 114, an inner panel 120, a window 130, and an interior trim 140. As shown in FIG. 2, the lower outer panel 114 has a flange portion 114a that extends into the window 130. Similarly, the inner panel 120 also has a flange portion 120a that extends into the window 130. Then, the outer surface of the flange portion 114a of the lower outer panel 114 is adhered to the window 130 with an adhesive 150a, and the inner surface of the flange portion 114a is adhered to the flange portion 120a of the inner panel 120 with an adhesive 150b, whereby the window 130, the lower outer panel 114, and the inner panel 120 are adhered (see, for example, Patent Document 1 and Patent Document 2). Further, the interior trim 140 is also adhered to the window 130 with an adhesive 150c. In a region of the window 130 where these members are arranged, a coloring portion 162 is provided to make the internal structure difficult to be visually recognized from the outside. Further, an exterior coating 160 is applied to the outside of the vehicle body of the window 130 and the lower outer panel 114 so as to cover them.

[0004] Furthermore, in recent years, in order to reduce the weight of the vehicle body, resin components have been used for parts such as outer and inner panels, and transparent resin glass has been used for windows. Patent Document 3 describes that in this case, resin window glass, a resin molded panel (corresponding to the outer panel), and a window frame placed inside the window glass and molded panel can be molded together as a single unit using a multi-color molding method. Patent Document 3 also states that by forming a stepped structure or a mating structure with grooves and protrusions at the joint between the window glass or molded panel and the window frame, the bonding area can be increased and the bonding strength can be improved.

[0005] Furthermore, Patent Document 4 describes a resin glass in which a protrusion is provided on the opaque blackout portion at the periphery of the resin glass, and this protrusion can be inserted into the vehicle body (corresponding to the outer panel) to position it relative to the vehicle body.

[0007] There is a need to improve the adhesive strength between the window, outer panel, and inner panel compared to conventional window structures such as those described in Patent Documents 1 and 2.

[0008] In contrast, it is thought that providing stepped structures or interlocking structures, as described in Patent Document 3, between the window and the outer panel, and between the outer panel and the inner panel, would increase the bonding area and thus improve the bonding strength of these components. However, when such stepped structures or interlocking structures are bonded with adhesive, it is difficult to maintain a consistent adhesive thickness, which can lead to reduced adhesive application efficiency and decreased long-term stability of the adhesive strength.

[0009] Furthermore, in conventional window structures such as those described in Patent Documents 1 and 2, when stress is applied to the window or outer panel, stress concentrates at the boundary between the window and the outer panel, sometimes causing paint cracking in the exterior coating 160 at the boundary. This problem was also observed in multi-color molded articles formed by the multi-color molding method described in Patent Document 3 and others.

[0010] The present invention has been made in view of the above problems, and aims to provide a window structure for a movable body that can more easily increase the joint strength of the window, outer panel and inner panel, and that is less prone to paint cracking, as well as a back door and a movable body having said window structure.

Brief Description of the Drawings

[0014] [Figure 1] FIG. 1 is a schematic view showing the appearance of a back door having a window portion. [Figure 2] FIG. 2 is a schematic cross-sectional view taken along the dashed line A-A of FIG. 1, showing a conventional configuration in which a window portion is assembled to an outer panel (lower outer panel) and an inner panel. [Figure 3] FIG. 3 is another schematic cross-sectional view taken along the dashed line A-A of FIG. 1, showing a configuration in which a window is assembled to a lower outer panel and an inner panel in the window structure according to the first exemplary embodiment of the present embodiment. [Figure 4] FIG. 4 is another schematic cross-sectional view taken along the dashed line A-A of FIG. 1, showing a configuration in which a window is assembled to a lower outer panel and an inner panel in the window structure according to the second exemplary embodiment of the present embodiment. [Figure 5]Figure 5 is another schematic cross-sectional view along the dashed line AA in Figure 1, showing a configuration in which the window is assembled to the lower outer panel and the inner panel in a window structure according to a third exemplary embodiment of this embodiment. [Modes for carrying out the invention]

[0015] [First Embodiment] A first exemplary embodiment of the present invention relates to a window structure in the back door of an automobile, the schematic appearance of which is shown in Figure 1. As shown in Figure 1, the back door 100 according to this embodiment has an upper outer panel 112, a lower outer panel 114, an inner panel 120, and a window 130. Also, as shown in Figure 1, the back door 100 may have a taillight and brake light 170 on either the left or right side, and a license plate mounting portion 180.

[0016] Figure 3 is a schematic cross-sectional view taken along the dashed line AA in Figure 1, showing the configuration in which the window 130 is assembled to the lower outer panel 114 and the inner panel 120 in the window structure 300 of this embodiment.

[0017] In this embodiment, the window 130 has a protrusion 132 that projects inward toward the vehicle body. The height of the protrusion 132 toward the vehicle body is approximately the same as the thickness of the lower outer panel 114. In this specification, "approximately the same" means that the value of the smaller of the two is within 10% of the value of the larger of the two.

[0018] The lower outer panel 114 has a stepped structure portion 114b that is bent along the window 130, and a flange portion 114a at its tip that extends into the interior of the window 130. The lower outer panel 114 is positioned so that the flange portion 114a is in contact with the window 130, and the side of the flange portion 114a on the window 130 side (the side on the exterior side of the vehicle body) and the side of the window 130 on the flange portion 114a side (the side on the interior side of the vehicle body) are bonded together with adhesive 150a. In this specification, the term "positioned in contact" of two members includes not only a configuration in which these members are simply in contact in a separable manner, but also a configuration in which they are bonded or joined together by adhesive or other methods.

[0019] The extending length of the flange portion 114a is not particularly limited, but it is preferable that it be approximately the same length as the length from the end of the window 130 on the lower outer panel 114 side (the end on the lower side of the vehicle body) to the end of the protrusion 132 on the lower outer panel 114 side (the end on the lower side of the vehicle body). This maximizes the bonding area of ​​the adhesive 150a, thereby increasing the bonding strength between the window 130 and the lower outer panel 114. In addition, when bonding the window 130 and the lower outer panel 114, the tip of the flange portion 114a can be brought into contact with the protrusion 132 to position the lower outer panel 114, making it less likely for misalignment to occur when bonding the window 130 and the lower outer panel 114.

[0020] The inner panel 120 has a flange portion 120a that extends into the interior of the window 130. The inner panel 120 is positioned so that the flange portion 120a is in contact with the flange portion 114a of the lower outer panel 114, and the side of the flange portion 120a facing the window 130 (the side facing the outside of the vehicle body) and the side of the flange portion 114a facing the inner panel 120 (the side facing the inside of the vehicle body) are bonded together with adhesive 150b. In this way, the inner panel 120 is sandwiched between the lower outer panel 114 and the window 130 and positioned in contact with them.

[0021] The extended length of the flange portion 120a is longer than the extended length of the flange portion 114a of the lower outer panel 114, and also longer than the length from the peripheral edge of the window 130 (the lower end of the vehicle body) to the peripheral edge of the protrusion 132 (the lower end of the vehicle body). In other words, the flange portion 120a extends from the peripheral edge of the window 130 to the same position as the protrusion 132, or even beyond the protrusion 132. This extended flange portion 120a and the side of the protrusion 132 on the inner panel 120 side (the side on the inside of the vehicle body) are bonded together by adhesive 150b.

[0022] In this embodiment, the inner panel 120 is bonded to the lower outer panel 114 with adhesive 150b, and at the same time, it is bonded to the protrusion 132 of the window 130 with adhesive 150b. By bonding the inner panel 120 to the window 130 in this way, the adhesive strength of the window 130, the lower outer panel 114, and the inner panel 120 can be further increased.

[0023] Furthermore, in this embodiment, the window 130 is bonded to the lower outer panel 114 with adhesive 150a, and separately, it is bonded to the inner panel 120 at the protrusion 132 with adhesive 150b. By bonding the window 130 to the inner panel 120 at the protrusion 132, the stress applied to the window 130 is distributed to the bonded portion at the protrusion 132, making it less likely for stress to concentrate at the boundary 130a between the window 130 and the lower outer panel 114. As a result, it is less likely for paint cracking to occur at the boundary 130a due to slight deflection of each component caused by the above stress.

[0024] Furthermore, in this embodiment, by making the height of the protrusion 132 approximately the same as the thickness of the lower outer panel 114, the contact portion 152 between the inner panel 120 and the protrusion 132 can be made the same height as the contact portion 154 between the inner panel 120 and the lower outer panel 114 (the distance from the window can be made the same). In other words, the contact portion 152 and the contact portion 154 can be arranged continuously on the same straight line or curve. This makes it possible to make the thickness of the adhesive 150b the same for the contact portion 152 and the contact portion 154, and to uniformly apply the adhesive 150b to these contact portions during assembly, resulting in good applicability of the adhesive 150b and making it less likely for the long-term stability of the adhesive strength to decrease due to uneven application.

[0025] The protrusion 132 on the window 130 may be formed by designing and molding the window 130 to have that shape, or the protrusion 132 may be used as an insertion hole for a painting mask jig used to prevent paint from adhering to the transparent part of the window 130 when painting the vehicle body. In the latter case, as shown in Figure 3, the protrusion 132 becomes a fitting portion into which the window 130 is fitted to the inside of the vehicle body. At this time, the depth of the fitting portion may be adjusted to match the thickness of the lower outer panel 114, or the thickness of the flange portion 114a may be adjusted to match the depth of the fitting portion.

[0026] In this embodiment, the interior trim 140 is bonded to the window 130 with adhesive 150c. However, the bonding position of the interior trim 140 is not limited to this, and it may be bonded to another component, such as the inner panel 120.

[0027] Furthermore, in the area of ​​the window 130 where the lower outer panel 114 (flange portion 114a), inner panel 120 (flange portion 120a), and interior trim 140 are located on the interior side of the vehicle body, a colored portion 162 is provided on the interior side of the vehicle body to make these internal structures difficult to see from the outside.

[0028] Furthermore, the exterior paint 164 of the vehicle body is applied to the area of ​​the window 130 where the lower outer panel 114 (flange portion 114a) is located on the interior side of the vehicle body, and to the portion of the lower outer panel 114 that is exposed to the exterior of the vehicle body. When the insertion hole of the painting mask jig is a protrusion 132, the exterior paint 164 is not applied to the area of ​​the window 130 where the protrusion 132 and the adhesive portion between the inner panel 120 (flange portion 120a) and the protrusion 132 are located on the interior side of the vehicle body (see Figure 3). Note that the colored portion 162 does not need to be applied to the area of ​​the window 130 where the exterior paint 164 is applied (the area where the lower outer panel 114 (flange portion 114a) is located on the interior side of the vehicle body).

[0029] (material) The lower outer panel 114, inner panel 120, and interior trim 140 can be made from any material conventionally used in moving objects, such as metal and resin.

[0030] Examples of the above metals include aluminum and its alloys, as well as iron or its alloys such as stainless steel.

[0031] Examples of the above resins include thermoplastic polyester resins such as polycarbonate, polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate; polystyrene resins, high-impact polystyrene resins (HIPS); styrene-based resins such as acrylonitrile-styrene copolymer (AS resin), acrylonitrile-butadiene-styrene copolymer (ABS resin), acrylonitrile-styrene-acrylic rubber copolymer (ASA resin), and acrylonitrile-ethylene propylene rubber-styrene copolymer (AES resin); polyolefins such as polyethylene and polypropylene; polyamides, polyimides, polyetherimides, polyurethanes, polyphenylene ethers, polyphenylene sulfides, polysulfones, and polymethacrylates. Of these, polyolefins are preferred, and polypropylene is more preferred, because they have a low specific gravity, can reduce the weight of the moving body when used for these large-area components, have good processability, and have good surface gloss, making it easy to enhance the design.

[0032] Window 130 can be made of light-transmitting materials conventionally used in moving objects, such as quartz glass or resin glass.

[0033] Examples of the above-mentioned resin glass include styrene-based resins such as polystyrene resin, high-impact polystyrene resin (HIPS), acrylonitrile-styrene copolymer (AS resin), acrylonitrile-butadiene-styrene copolymer (ABS resin), acrylonitrile-styrene-acrylic rubber copolymer (ASA resin), and acrylonitrile-ethylene propylene rubber-styrene copolymer (AES resin); acrylic-based resins such as polyalkyl methacrylate and polymethacrylic methacrylate; polyphenyl ether, polycarbonate, amorphous polyalkylene terephthalate, polyester, amorphous polyamide, polyolefins such as poly-4-methylpentene-1 and cyclic polyolefins; amorphous polyarylate, polyethersulfone, styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, polyamide-based thermoplastic elastomers, polyester-based thermoplastic elastomers, and polyurethane-based thermoplastic elastomers. Of these, polycarbonate, and especially aromatic polycarbonate, is preferred due to its high impact resistance and heat resistance.

[0034] For adhesive 150, known adhesives such as urethane-based adhesives can be used.

[0035] [Second Embodiment] Figure 4 is another schematic cross-sectional view along the dashed line AA in Figure 1, showing a configuration in which the window 130 is assembled to the lower outer panel 114 and the inner panel 120 in a window structure 400 according to a second exemplary embodiment of this present invention.

[0036] The window structure 400 differs from the window structure 400 of the first embodiment in that it is a multi-color molded body in which a resin window 130 and a resin lower outer panel 114 are integrally molded by multi-color molding, but in other respects it is substantially the same as the window structure 300 of the first embodiment. The following description will omit details of the configuration common to the first embodiment.

[0037] In this embodiment, the stepped structure portion 114b of the lower outer panel 114, which is bent along the window 130, and the flange portion 114a, which extends into the interior of the window 130, are joined to the window 130 by integral molding. For this reason, in this embodiment, the colored portion 162 is not provided in the area of ​​the window 130 where the lower outer panel 114 (flange portion 114a) is located on the interior side of the vehicle body.

[0038] According to this embodiment, since the window 130 and the lower outer panel 114 are integrally molded and modularized, bonding them with adhesive 150a is unnecessary. Therefore, assembly can be made easier.

[0039] On the other hand, the inner panel 120, which often has a complex shape, would require a complex mold if it were to be integrally molded, making molding difficult. Therefore, it is better to mold it separately and then assemble it. In this case, according to this embodiment, as in the first embodiment, the adhesive strength of the window 130, the lower outer panel 114, and the inner panel 120 can be further increased by bonding the inner panel 120 not only to the lower outer panel 114 but also to the window 130.

[0040] Furthermore, in this embodiment as well, by making the height of the protrusion 132 approximately the same as the thickness of the lower outer panel 114, the thickness of the adhesive 150b is made the same for the contact portion 152 and the contact portion 154. This makes it possible to uniformly apply the adhesive 150b to these contact portions during assembly, resulting in good applicability of the adhesive 150b and making it less likely for the long-term stability of the adhesive strength to decrease due to uneven application.

[0041] [Third Embodiment] Figure 5 is another schematic cross-sectional view along the dashed line AA in Figure 1, showing a configuration in which the window 130 is assembled to the lower outer panel 114 and the inner panel 120 in a window structure 500 according to a third exemplary embodiment of this embodiment. Note that Figure 5 shows the assembly portion of the window 130 to the lower outer panel 114 and the inner panel 120 in a more enlarged view than in Figures 3 and 4.

[0042] The window structure 500 differs from the window structure 400 according to the second embodiment in that the lower outer panel 114 has a through hole 114c. The following description will omit details of components common to the second embodiment.

[0043] The through-hole 114c penetrates the flange portion 114a of the lower outer panel 114 from the side facing the inner panel 120 (the side facing the inside of the vehicle body) to the side facing the window 130 (the side facing the inside of the vehicle body), and opens into the window 130. When the lower outer panel 114 and the inner panel 120 are assembled, a portion of the adhesive 150b used to bond them flows into the through-hole 114c, reaches the window 130, and hardens. The adhesive 150b that fills the inside of the through-hole 114c and bonds the lower outer panel 114 and the inner panel 120 further bonds the window 130 to these components. Therefore, the adhesive strength of the lower outer panel 114, the inner panel 120, and the window 130 can be further increased.

[0044] The opening width of the through-hole 114c is preferably greater than the thickness of the lower outer panel 114, and specifically can be about 3 to 10 mm in both the vertical and horizontal directions of the vehicle body. The shape of the opening is not particularly limited and may be circular, elliptical, oblong, polygonal (such as a square), or other irregular shapes.

[0045] In this embodiment, the through-hole 114c is located at the end of the flange portion 114a on the stepped structure portion 114b side, corresponding to the peripheral edge end of the window 130 (the end on the lower side of the vehicle body). The wall surface of the through-hole 114c on the stepped structure portion 114b side (lower side of the vehicle body) lies on the same straight line as the lower outer panel 114 at the stepped structure portion 114b and the side surface of the peripheral edge end of the window 130 (the side surface on the lower side of the vehicle body) in the cross-section shown in Figure 5. By positioning the bonding portion formed by the through-hole 114c closer to the end of the flange portion 114a on the stepped structure portion 114b side, the bonding strength between the lower outer panel 114 and the window 130 near the stepped structure portion 114b is increased, improving cross-sectional rigidity and making it less likely for paint cracking to occur at the boundary portion 130a due to stress on the boundary portion 130a between the window 130 and the lower outer panel 114.

[0046] In this embodiment, the portion of the inner panel 120 corresponding to the through hole 114c is further configured as a protruding portion 120b that extends toward the through hole 114c. The protruding portion 120b acts as a barrier, blocking the flow of adhesive 150b outward (downward in Figure 5) from between them due to the pressure when assembling the lower outer panel 114 and the inner panel 120. This barrier promotes the flow of adhesive 150b toward the through hole 114c. As a result, the adhesive 150b can be more effectively filled into the through hole 114c.

[0047] Furthermore, in this embodiment, the protrusion 120b is positioned at the end of the adhesive 150b when assembled (the end on the lower side of the vehicle body in Figure 5). This arrangement prevents the adhesive 150b from flowing out to the outside when assembling the lower outer panel 114 and the inner panel 120, and further efficiently promotes the flow of the adhesive 150b towards the through hole 114c.

[0048] [Other embodiments] It should be noted that the embodiments described above are merely illustrative embodiments of the present invention, and it goes without saying that the present invention can take various modified forms within the scope of the technical concept disclosed herein.

[0049] For example, the embodiments described above described a window structure including the lower outer panel 114 and the window 130 in a car back door having an upper outer panel 112 and a lower outer panel 114. In contrast, the present invention can also be applied to a window structure including the upper outer panel 112 and the window 130, and can also be applied to a window structure including an outer panel in which the upper outer panel 112 and the lower outer panel 114 are integrated and the window 130. Furthermore, the structure described above is not limited to the structure at the vertical end of the window 130 in the vehicle body direction, but may also be adopted at the horizontal end of the vehicle body.

[0050] Furthermore, in the third embodiment, a configuration was described in which the inner panel 120 has through holes 114c in a second embodiment in which the resin window 130 and the resin lower outer panel 114 are multi-color molded. However, as in the first embodiment, the inner panel 120 may also have through holes 114c in an embodiment in which the lower outer panel 114, the inner panel 120 and the window 130 are bonded together. Moreover, unlike the first and second embodiments, even when the window 130 and the inner panel 120 are not bonded together by the protrusions 132, the lower outer panel 114, the inner panel 120 and the window 130 may be bonded together by adhesive 150a filled into the through holes 114c in the inner panel 120.

[0051] The window structure may have multiple through holes 114c, in which case some of the through holes 114c do not need to be filled with adhesive 150b.

[0052] Furthermore, while the above-described embodiments have explained the window structure in the back door of an automobile, the same window structure may also be adopted for the sides, top, front, etc., of an automobile.

[0053] Furthermore, the above-described window structure may be applied not only to automobiles, but also to all kinds of moving objects such as flying cars, buses, trucks, trains, airplanes, helicopters, and ships. [Industrial applicability]

[0054] The window structure according to the present invention can increase joint strength and make it less prone to paint cracking. [Explanation of Symbols]
