Description

  The present invention relates to a panel assembly including a laminated panel and a support member that supports the laminated panel, and more particularly to a panel assembly including a laminated panel in which a glass panel and a resin panel are laminated, and a laminated panel support structure in a vehicle body.

  Conventionally, glass panels made of inorganic glass are widely used for vehicles. Since glass panels are heavy, for example, they are bonded onto at least one surface of a translucent resin plate in order to reduce the weight. A laminated panel in which glass thin plate layers are laminated via an agent layer is known (Patent Document 1). According to Patent Document 1, by adopting such a configuration, the laminated panel can be provided with scratch resistance equivalent to that of inorganic glass, and light weight can be achieved as compared with the case where it is configured by a single glass plate. I can do it.

Japanese Utility Model Publication No. 64-27234

  In general, a vehicle panel assembly using a laminated panel in which a glass panel and a resin panel are laminated includes a support member that supports a transparent plate such as inorganic glass from the vehicle interior side. From the viewpoint of scratch resistance, the laminated panel has a glass panel arranged outside the vehicle and a resin panel arranged inside the vehicle. For this reason, the support member is bonded and fixed to the resin panel to support the entire laminated panel.

  Many of the panel assemblies include a sealing member that surrounds the laminated panel. The seal member is a member that watertightly seals between the vehicle body opening and the laminated panel when the panel assembly closes the vehicle body opening formed in the roof or the like of the vehicle body. In order to prevent a load from being directly applied to the laminated panel when the panel assembly closes the vehicle body opening, the seal member is usually disposed on the outer edge of the support member.

  Here, the resin panel has a larger linear expansion coefficient (thermal expansion coefficient) than that of the glass panel, and the resin panel mainly expands or contracts with a change in environmental temperature or the like. For example, in a low temperature environment, the resin panel contracts, and the support member bonded to the resin panel is displaced or deformed as the resin panel contracts. As a result, the seal member provided on the support member is also displaced. For this reason, when the resin panel contracts, the gap between the laminated panel and the vehicle body opening is enlarged.

  However, Patent Document 1 does not mention any adverse effects caused by expansion or contraction of the resin panel. When the laminated panel is to be introduced into, for example, a sunroof, the sealing member is taken into consideration when the shape of the resin panel contracts. It was necessary to design a large size in advance. That is, even when the gap between the vehicle body opening and the laminated panel is enlarged, there is a problem that the sealing member is enlarged due to the need to ensure the sealing performance.

  The present invention has been devised to solve such problems of the prior art, and its main purpose is that even when the environmental temperature changes and the resin panel expands or contracts, An object of the present invention is to provide a panel assembly capable of reducing a change in a gap between an opening and a laminated panel and miniaturizing a seal member, and a laminated panel support structure in a vehicle body.

  The present invention made in order to solve the above problems includes a first panel (12) and a laminated panel having a second panel (13) laminated on the first panel and having a larger linear expansion coefficient than the first panel. (11) and a support member (15) provided on the second panel side of the laminated panel to support the laminated panel, wherein the first panel is further outward from an outer edge of the second panel. The support member is bonded to the main surface (12b) of the first panel on the second panel side in the extension portion. Panel assembly (10).

  As a result, even if the environmental temperature changes and the resin panel constituting the laminated panel expands or contracts, the support member that supports the laminated panel is not affected by the deformation of the resin panel. With the assembly installed, it is possible to reduce the change in the gap between the opening and the laminated panel.

  In the present invention, the extending portion (12a) is provided over the entire circumference of the first panel (11), and the support member (15) is configured in a frame shape so as to support the first panel over the entire circumference. And a sealing member (16) surrounding the supporting member is provided along the outer edge of the supporting member.

  Thereby, in a state where the panel assembly is installed, the change in the gap between the opening and the laminated panel can be reduced over the entire circumference of the opening, and the seal member can be downsized.

  Further, according to the present invention, the support member (15) includes an extending portion (a portion extending toward the center of the main surface of the second panel along the main surface (13b) of the second panel (13)). 15a), and a regulating member (17) that is provided along an edge on the central side of the extended portion and restricts displacement of the second panel toward the extended portion. .

  As a result, even if an external force is applied to the laminated panel, the regulating member regulates the displacement of the laminated panel toward the extending portion side. Therefore, the laminated panel is supported more stably by the support member, and the laminated panel can be damaged. It becomes possible to prevent.

  In the present invention, the first panel (12) is made of glass, and the second panel (13) is made of resin.

  Accordingly, since the glass panel has high scratch resistance, it is possible to prevent the laminated panel from being damaged by disposing the glass panel outside the vehicle body.

  The present invention also includes a first panel (12), a laminated panel (11) that is laminated on the first panel and has a second panel (13) that has a larger linear expansion coefficient than the first panel, 1), or a support member (15) connected to a part of the vehicle body and provided on the second panel side of the laminated panel to support the laminated panel. The panel includes an extension portion (12a) that extends further outward from an outer edge of the second panel, and the support member has a main surface on the second panel side of the first panel in the extension portion ( 12b) is a structure for supporting a laminated panel in a vehicle body.

  Thus, even when the environmental temperature changes and the resin panel constituting the laminated panel expands or contracts, the support member that supports the laminated panel is not affected by the deformation of the resin panel. With the panel attached to the vehicle body, the change in the gap between the vehicle body opening and the laminated panel can be reduced.

  According to the present invention, even when the environmental temperature changes and the resin panel constituting the laminated panel expands or contracts, the panel assembly is placed between the opening and the laminated panel. It is possible to reduce the change in the gap.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In addition, about the direction used for description, it shall follow the description of the direction in each figure. Here, “Right” and “Left” correspond to the directions viewed from the occupant who has boarded the vehicle.

  FIG. 1 is an explanatory diagram showing an outline of a sunroof device 4 mounted on the vehicle body 1. As shown in the figure, the roof 2 of the vehicle body 1 is provided with a rectangular vehicle body opening 3 in a top view. A sunroof device 4 is attached to the vehicle body opening 3. The sunroof device 4 includes a panel assembly 10. The panel assembly 10 is mechanically connected to a driving source (not shown) and is configured to be displaceable in the front-rear direction with respect to the vehicle body opening 3. The sunroof device 4 is of a so-called tilt inner type. When the sunroof device 4 is in the open state, the panel assembly 10 is provided between the roof 2 and an interior material (not shown) behind the vehicle body opening 3. In the closed state, the panel assembly 10 reaches the front edge of the vehicle body opening 3, and the seal member 16 (see FIG. 2) is connected to the front edge, rear edge, and side edge of the vehicle body opening 3. Is pressed against the vehicle body opening 3 to be watertightly closed.

  FIG. 2 is an exploded perspective view showing the configuration of the panel assembly 10 according to the first embodiment of the present invention, and FIG. 3 is a perspective view of the laminated panel 11 constituting the panel assembly 10 as seen from the resin panel 13 side. . Hereinafter, the configuration of the panel assembly 10 according to the first embodiment will be described with reference to FIGS. 2 and 3.

  As shown in FIG. 2, the panel assembly 10 includes a laminated panel 11, a holder 15 as a support member that supports the laminated panel 11, a seal member 16, and a regulating member 17. The laminated panel 11 is obtained by laminating a glass panel (first panel) 12, an adhesive medium 14, and a resin panel (second panel) 13, and the laminated panel 11 is reduced in weight by using the resin panel 13 as a part thereof. Is done. The holder 15 is a frame that is slightly larger than the glass panel 12, and includes a connecting portion (not shown) that connects the panel assembly 10 to the vehicle body 1 (see FIG. 1) at the lower portion in the left-right direction. In a state where the panel assembly 10 is attached to the vehicle body 1, the glass panel 12 of the laminated panel 11 is disposed above (outside the vehicle body 1), and the resin panel 13 is disposed below (inside the vehicle body 1). Since the glass panel 12 has high scratch resistance, the outer surface of the laminated panel 11 is hardly damaged by scratching.

  As the glass panel 12, transparent tempered glass manufactured by rapidly cooling float glass is used. The resin panel 13 is obtained by injection molding a highly transparent thermoplastic resin. Here, polycarbonate is used as the resin. In addition, as a material of the resin panel 13, acrylic can also be used.

here,
When the linear expansion coefficient of glass is αg, αg = 8.3 × 10 ⁻⁶ / ° C.
When the linear expansion coefficient of polycarbonate is αp, αp = 70 × 10 ⁻⁶ / ° C.
Assuming that the linear expansion coefficient of acrylic is αa, αa = 70 to 80 × 10 ⁻⁶ / ° C.
In general, the linear expansion coefficient of the resin panel 13 is one order of magnitude larger than that of the glass panel 12. That is, when the environmental temperature changes, the resin panel 13 expands or contracts more than the glass panel 12.

  The main surface 13b of the resin panel 13 is configured to be smaller than the main surface 12b of the glass panel 12 (see FIG. 3), and the center of the main surface 12b of the glass panel 12 and the center of the main surface 13b of the resin panel 13 are approximately. Laminated to match. In a state in which the resin panel 13 and the glass panel 12 are laminated, the glass panel 12 includes an extension portion 12 a that extends further outward from the outer edge of the resin panel 13, and the extension portion 12 a is an outer edge of the resin panel 13. Is formed in a band shape over the entire circumference of the glass panel 12. The laminated panel 11 includes an adhesive medium 14 provided between the glass panel 12 and the resin panel 13. The adhesive medium 14 has substantially the same shape as the resin panel 13, and the adhesive medium 14 adheres the glass panel 12 and the resin panel 13 in the entire range where the glass panel 12 and the resin panel 13 overlap.

  Here, a sheet material mainly made of PVB (polyvinyl butyral) is used as the adhesive medium 14. PVB is excellent in transparency and moldability, and does not lose flexibility even when the glass panel 12 and the resin panel 13 are pressed. Due to this characteristic, when the resin panel 13 expands or contracts, the outer edge of the resin panel 13 is relatively displaced along the main surface 12 b of the glass panel 12. Moreover, by using PVB, even if the glass panel 12 is broken, scattering of glass fragments can be prevented, and sound insulation can be improved. Here, the glass panel 12 has a thickness of, for example, 1.6 mm, the resin panel 13 has a thickness of 1.5 mm, and the adhesive medium 14 has a thickness of about 0.8 mm.

The holder 15 is an integrally molded product obtained by, for example, pressing a cold-rolled steel sheet having a tensile strength of 270 N / mm ² or more, and has a thickness of about 0.8 to 1.6 mm, for example. The holder 15 is bonded to the glass panel 12 from the indoor side in the above-described extending portion 12 a, whereby the entire laminated panel 11 is supported by the holder 15. Note that the linear expansion coefficient αs of the steel material constituting the holder 15 is, for example, αs = 11.7 × 10 ⁻⁶ / ° C., and the linear expansion coefficient of the holder 15 is approximately the same as the linear expansion coefficient αg of the glass panel 12. It is.

  In addition, a regulating member 17 made of, for example, rubber is provided on the inner edge of the holder 15 formed in a frame shape. A seal member 16 made of rubber or the like is provided on the outer edge of the holder 15 so as to surround the entire circumference of the holder 15. Alternatively, the panel assembly 10 may be configured such that the holder 15 is formed of separate parts on the front, rear, left, and right sides, and these are individually bonded to the corresponding portions of the glass panel 12. In this case, the seal member 16 is bridged around the outer edge of the holder 15 divided into four parts.

  FIG. 4 is a side sectional view of a main part of the panel assembly 10. 4 corresponds to the IV-IV cross section in FIG. 4 illustrates a state immediately before the panel assembly 10 constituting the sunroof device 4 (see FIG. 1) is closed (when the seal member 16 contacts the vehicle body opening 3).

  Hereinafter, the configuration of the panel assembly 10 in the vicinity of the front edge of the vehicle body opening 3 (see FIG. 1) will be described. As described above, the holder 15 has a frame shape along the outer periphery of the laminated panel 11, the seal member 16 attached to the holder 15 also has an annular shape, and the panel assembly 10 has a front edge portion shown in FIG. The configuration is almost the same as that.

  In the following description, the term “adhesive” does not have a strict meaning of a substance used for bonding the surfaces of solid objects, but is a substance that can be used to bond two objects or has been cured. In the case where the adhesive has a high barrier property against gas or liquid, it is used in a broad sense as a substance having a function as a sealing material.

  As shown in the drawing, the holder 15 includes a base 15b provided on the outer edge (front) side of the glass panel 12 along the main surface 12b of the glass panel 12, and a resin panel 13 (the glass panel 12 and the resin panel 13 are laminated). And an extended portion 15a extending toward the center (rear) of the main surface 13b of the resin panel 13 along the main surface 13b of the laminated portion).

  A convex portion 15c protruding upward is provided between the base portion 15b and the extending portion 15a, and the extending portion 15a and the base portion 15b form a concave portion relative to the convex portion 15c. Thus, the strength of the holder 15 is improved by forming the holder 15 which is a frame body into a shape having irregularities from the inner edge to the outer edge. The extended portion 15a, the base portion 15b, and the convex portion 15c are each provided with flat surfaces 15h, 15f, and 15g formed substantially in parallel with the main surface 13b of the glass panel 12 or the resin panel 13 below the laminated panel 11.

  Hereinafter, the peripheral configuration of the base portion 15b of the holder 15 will be described. A seal member 16 is disposed on the base portion 15b. The seal member 16 has a seal outer edge portion 16a having a hollow cross-sectional structure on the outer edge side (front side) and a supported portion 16b on the inner edge side (rear side). The seal outer edge portion 16a and the supported portion 16b A groove 16c that is recessed from the surface of the seal member 16 is formed on the lower surface therebetween. Also, an opening-side tongue piece 16g protruding toward the vehicle body opening 3 is provided below the seal outer edge portion 16a, and an adhesive reservoir 16d is formed on the upper surface of the supported portion 16b. A tongue piece 16f is provided so as to cover from above. A notch 16e is formed along the inner edge below the supported portion 16b. When the panel assembly 10 is in the closed state in the sunroof device 4 (see FIG. 1), the seal outer edge portion 16a is pressed against the front edge of the vehicle body opening 3 and deformed in the front-rear direction, so that the seal outer edge portion 16a is formed in the vehicle body opening 3. Further, the opening side tongue piece 16g comes into close contact with each other, and the space between the vehicle body opening 3 and the seal outer edge portion 16a is in a watertight state.

  An outer frame 15d is formed on the outermost edge (frontmost) of the holder 15 upward from the flat surface 15f of the base portion 15b. An outer frame 15 d is fitted in the groove portion 16 c provided in the seal member 16, whereby the seal member 16 is attached to the outer edge of the holder 15.

  The supported portion 16b is sandwiched and supported by the laminated panel 11 (more precisely, the glass panel 12) and the holder 15 in the panel assembly 10. On the other hand, the supported portion 16b supports the holder 15 and the laminated panel. 11 is regulated.

  The adhesive reservoir 16d is filled with the adhesive 20, and the laminated panel 11 (glass panel 12) and the seal member 16 are joined in a watertight manner by the adhesive 20 filled in the adhesive reservoir 16d.

  Next, the peripheral configuration of the extending portion 15a of the holder 15 will be described. The innermost edge of the extended portion 15a is provided with a flat surface 15e parallel to the resin panel 13, and a regulating member 17 having a substantially U-shaped cross section corresponding to the shape of the flat surface 15e is attached to the flat surface 15e. Yes. As shown in the drawing, the upper surface of the restricting member 17 forms a flat surface 17 a, and the flat surface 17 a is disposed so as to face the resin panel 13. The restricting member 17 is made of an elastic material such as rubber, and restricts the resin panel 13 (laminated panel 11) from being displaced toward the extending portion 15a (that is, downward). Since the downward displacement of the laminated panel 11 is restricted by the regulating member 17, the laminated panel 11 is stably supported by the holder 15 even when an external force is applied to the laminated panel 11 from above, and the laminated panel 11 is damaged. Etc. are prevented. In FIG. 4, the regulating member 17 is provided apart from the resin panel 13, but the regulating member 17 is previously brought into contact with the resin panel 13 when no external force is applied to the laminated panel 11. May be.

  Next, the peripheral configuration of the convex portion 15c of the holder 15 will be described. The flat surface 15g formed on the convex portion 15c is not in contact with the single-layer portion composed of only the glass panel 12 of the laminated panel 11, that is, the extended portion 12a (see also FIG. 2). Yes. As described above, the separation distance between the holder 15 and the laminated panel 11 is regulated by the supported portion 16b, whereby the extension portion 12a and the flat surface 15h are arranged apart from each other.

  A region S1 extending from the flat surface 15g formed on the convex portion 15c to the flat surface 15f of the base portion 15b is filled with the adhesive 20, whereby the glass panel 12 is bonded and fixed to the holder 15. More specifically, in the area S1, the main surface 12b on the resin panel 13 side of the glass panel 12 constituting the laminated panel 11 is bonded to the holder 15 (its convex portion 15c). Further, the adhesive 20 contacts the innermost edge of the supported portion 16b of the seal member 16, and is filled in a notch 16e formed on the lower surface of the supported portion 16b. By filling the notch 16e with the adhesive 20, the seal member 16 is reliably prevented from coming out in the outer edge (front) direction. Thus, the three of the glass panel 12, the holder 15, and the seal member 16 are fixed to each other by the adhesive 20 filled in the region S1. Note that a urethane-based adhesive may be used as the adhesive 20, and it is particularly preferable to use a highly elastic and highly viscous type.

  Thus, in 1st Embodiment, the glass panel 12 contains the extension part 12a extended further outward from the outer edge of the resin panel 13, and the resin panel 13 side of the glass panel 12 in the extension part 12a The main surface 12b is bonded to a holder 15 as a support member. For this reason, in the configuration in which the laminated panel 11 is supported by the holder 15, the holder 15 does not have a direct connection portion with the resin panel 13. As described above, since the linear expansion coefficient αg of the glass panel 12 is sufficiently smaller than the linear expansion coefficient αp of the resin panel 13 (polycarbonate), for example, the resin panel 13 expands or contracts due to an environmental temperature change. Even in this case, the holder 15 that supports the laminated panel 11 is not affected by the deformation of the resin panel 13, and enlargement or reduction of the outer edge of the seal member 16 provided on the holder 15 can be minimized. That is, when the panel assembly 10 is attached to the vehicle body 1 (see FIG. 1), the change in the gap between the vehicle body opening 3 and the laminated panel 11 is reduced. As a result, even if the size of the seal member 16, particularly the seal outer edge portion 16a, is reduced, the space between the vehicle body opening 3 and the panel assembly 10 can be watertightly closed.

Further, as described above, the holder 15 is made of an iron-based material, and the linear expansion coefficient αs (= 11.7 × 10 ⁻⁶ / ° C.) of the holder 15 is the linear expansion coefficient αg (= 8. 3 × 10 ⁻⁶ / ° C.). The glass panel 12, the holder 15, and the sealing member 16 are fixed to each other by the adhesive 20, and the sealing member 16 is sandwiched between the glass panel 12 and the holder 15 in terms of configuration. If it is deformed, it can be stressed. Here, for example, assuming that the glass panel 12 extends forward due to thermal expansion, the holder 15 is bonded to the glass panel 12, so that when the glass panel 12 extends forward, the holder 15 also moves forward. It moves and no relative displacement occurs between them.

  However, relative displacement between the glass panel 12 and the holder 15 may occur in the outer edge portion of the region S <b> 1 where both are fixed by the adhesive 20 based on the difference in linear expansion coefficient between the glass panel 12 and the holder 15. However, since the length of the base portion 15b in the front-rear direction is short, the deformation amount itself is small, and the linear expansion coefficients of the glass panel 12 and the holder 15 are close to each other, so the deformation amount of the glass panel 12 and the holder 15 is You may consider that it is substantially the same. Therefore, no large shear stress acts on the adhesive 20 in the region S1, and the seal member 16 is not damaged. Further, since the sealing member 16 is made of an elastic body such as rubber, even if the glass panel 12 and the holder 15 are relatively displaced relatively, this displacement difference is absorbed by the deformation of the sealing member 16. .

  Next, an outline of the manufacturing process of the panel assembly 10 will be described with reference to FIGS. Here, the description will be made assuming that the process of manufacturing the laminated panel 11 using the glass panel 12, the resin panel 13, and the adhesive medium 14 has already been completed. In the manufacturing process of the panel assembly 10, first, the annular regulating member 17 is attached along the inner edge of the holder 15, and the groove portion 16 c of the seal member 16 is fitted into the outer frame 15 d of the holder 15 along the outer edge of the holder 15. Temporarily fasten with. Thereafter, the adhesive 20 is filled in the region S1. At this time, a discharge nozzle (not shown) for discharging the adhesive 20 is directed from the inner edge (rear) side of the holder 15 toward the cutout portion 16e of the seal member 16, and the adhesive discharged from the discharge nozzle. 20 fills the notch 16e and then fills the region S1. The adhesive 20 is filled while moving the discharge nozzle along the outer edge of the frame-shaped holder 15. At the same time, the adhesive 20 is filled into the adhesive reservoir 16d of the seal member 16 using another discharge nozzle.

  When the step of filling the adhesive 20 is completed, the laminated panel 11 is assembled from above the holder 15 where the adhesive 20 is exposed. At this time, the laminated panel 11 is assembled so as to cover the tip of the tongue piece 16f of the seal member 16 attached to the holder 15 over the entire circumference. That is, the tip end portion of the tongue piece 16f can be used as a positioning marker in the front-rear and left-right directions (see FIG. 2). The laminated panel 11 assembled to the holder 15 is positioned in the vertical direction by the supported portion 16b of the seal member 16, and the laminated panel 11 is layered with respect to the holder 15 (particularly, the range from the convex portion 15c to the flat surface 15f). It is supported via the adhesive 20. In this state, the adhesive 20 is cured, whereby the assembly of the panel assembly 10 is completed.

  FIG. 5 is a perspective view of a modified example of the laminated panel 11 constituting the panel assembly 10 as viewed from the resin panel 13 side. In the laminated panel 11 described with reference to FIG. 3, the adhesive medium 14 is sized to overlap the entire surface of the resin panel 13, but in the laminated panel 31 of the modified example, the adhesive medium 14 extends along the outer edge of the resin panel 13. The portion A1 (in FIG. 5, the portion between the outer edge of the resin panel 13 and the broken line) is provided in a band shape, and the space (part where the adhesive medium 14 is not interposed between the glass panel 12 and the resin panel 13. A2) is an air layer. The laminated panel 31 may be replaced with the laminated panel 11 shown in FIG. The laminated panel 31 having the configuration shown in FIG. 5 can also be employed in the second to fifth embodiments described below.

  In the laminated panel 31, since the air layer expands or contracts depending on the environmental temperature, the resin panel 13 may be provided with a communication hole that communicates the portion A2 (that is, the air layer) with the outside. Moreover, it is good also as a structure which ventilates the air in site | part A2 previously, and seals between the glass panel 12 and the resin panel 13 with the adhesive medium 14 provided in site | part A1. As described above, in the first embodiment, the direct connection between the holder 15 (see FIG. 4) and the resin panel 13 is eliminated, the holder 15 supports the glass panel 12, and the glass panel 12 supports the resin panel 13. It is set as the structure which supports, The structure which supports the resin panel 13 with the glass panel 12 can be selected arbitrarily. Thus, in the relationship between the glass panel 12 and the resin panel 13, the present invention can improve the design freedom of the panel assembly 10.

(Second Embodiment)
FIG. 6 is a sectional side view of the main part of the panel assembly 10 according to the second embodiment of the present invention, and FIGS. . 6 corresponds to the VI-VI cross section in FIG.

  In 1st Embodiment, the glass panel 12 has the extension part 12a in the outer edge of the resin panel 13, and the holder 15 was adhere | attached and fixed to the main surface 12b of the glass panel 12 in this extension part 12a. . In the second embodiment, the resin panel 13 is provided with a plurality of through holes 22 along the outer edge, and the main surface 12 b of the glass panel 12 is bonded and fixed to the holder 15 through the through holes 22. The point is a feature. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted (the same applies to the third to fifth embodiments).

  As illustrated, the holder 15 as a support member includes a base 15b provided on the outer edge (front) side of the glass panel 12 along the main surface 12b of the glass panel (first panel) 12, and a resin panel (second panel). The panel 15 includes an extended portion 15 a extending along the main surface 13 b of the panel 13 toward the center (rear) of the main surface 13 b of the resin panel 13.

  The extended portion 15a is provided with a convex portion 15c that protrudes upward with respect to the base portion 15b, and a flat surface 15i that is formed one step lower than the convex portion 15c from the convex portion 15c to the rear. ing. A recess 15j is formed further downward from the flat surface 15i, and a flat surface 15e having substantially the same height as the flat surface 15i is formed behind the recess 15j. A regulating member 17 is disposed on the flat surface 15e.

  Here, a through-hole 22 is provided in the resin panel 13 and the adhesive medium 14 at a position facing the flat surface 15i. An area 20 formed between the glass panel 12 and the holder 15 and inside the through hole 22 is filled with an adhesive 20, and the adhesive 20 forms a main surface 12 b on the resin panel 13 side of the glass panel 12. Bonded to the holder 15.

  As shown in FIGS. 7A and 7B, a plurality of through holes 22 are arranged along the outer edge of the resin panel 13 at a predetermined interval. The shape of the through hole 22 may be substantially circular as shown in FIG. 7A when viewed from above, and is substantially elliptical with a long hole in the direction along the outer edge of the resin panel 13 as shown in FIG. 7B. May be adopted. 7A and 7B, illustration of the adhesive medium 14 for bonding the glass panel 12 and the resin panel 13 in the laminated panel 11 is omitted, but the adhesive medium 14 excludes the range of the through holes 22. The resin panel 13 is superposed. In the second embodiment, when the panel assembly 10 is configured using the laminated panel 31 described with reference to FIG. 5, the through hole 22 may be provided in the portion A <b> 1 illustrated in FIG. 5.

  As shown in FIG. 6, in the second embodiment, similarly to the first embodiment, the glass panel 12 has an extending portion 12a extending further outward from the outer edge of the resin panel 13, and this extension In the portion 12a, the region S1 is also filled with the adhesive 20, and the holder 15 is connected to the main surface 12b of the glass panel 12 on the resin panel 13 side.

  Hereinafter, the outline of the manufacturing process of the panel assembly 10 in the second embodiment will be described with reference to FIG. First, the cover film on the surface of the adhesive medium 14 is peeled off, and the adhesive surface exposed on the surface is attached to the resin panel 13. Thereafter, the through hole 22 is formed along the outer edge of the resin panel 13 by, for example, punching while the back cover film remains. Next, the cover film on the back surface of the adhesive medium 14 is peeled off, and the laminate of the resin panel 13 and the adhesive medium 14 in which the through holes 22 are formed is superimposed on the glass panel 12 to create the laminated panel 11.

  Next, the annular regulating member 17 is attached along the inner edge of the holder 15, and the groove 16 c of the seal member 16 is fitted into the outer frame 15 d of the holder 15 along the outer edge of the holder 15 and temporarily fixed. Thereafter, the adhesive 20 is filled into the region S1 and the adhesive reservoir 16d while moving the coating nozzle.

  On the other hand, the adhesive 20 is also filled in the through hole 22 (region S2) formed in the resin panel 13 separately. In the second embodiment, the adhesive 20 is filled on the holder 15 side in the region S1, and the adhesive 20 is filled on the laminated panel 11 side through the through hole 22 in the region S2. By setting it as such a process, the adhesive agent 20 can be reliably filled into the through-hole 22. Then, when the process of filling the adhesive 20 is completed, the laminated panel 11 is assembled from above the holder 15 with the side filled with the adhesive 20 facing each other.

  As described above, in the second embodiment, the glass panel 12 is bonded to the holder 15 in the region S1 provided in a strip shape along the outer edge of the glass panel 12 and is located on the inner side (rear) of the region S1 when viewed from above. Thus, this is also bonded to the holder 15 in the region S2 provided in a band shape (but in a spot manner). By setting it as such a structure, compared with 1st Embodiment, it becomes possible to support the glass panel 12 to the holder 15 more firmly, and the intensity | strength as the whole panel assembly 10 improves. Of course, also in the second embodiment, the expansion or contraction of the resin panel 13 is absorbed by the adhesive 20 having high elasticity filled in the region S2, and the holder 15 that supports the laminated panel 11 is affected by the deformation of the resin panel 13. The effect that the expansion and contraction of the outer edge of the seal member 16 provided in the holder 15 is minimized is maintained.

  Now, as shown in FIG. 6, the adhesive 20 is filled so as to completely fit inside the through-hole 22, and the resin panel 13, the adhesive medium 14, and the adhesive 20 in the front-rear direction (and the left-right direction). In the meantime, it is desirable that a gap is formed as a margin in consideration of expansion and contraction of the resin panel 13 accompanying a change in environmental temperature.

  However, as described in the first embodiment, the urethane adhesive is used as the adhesive 20, and when the adhesive 20 has high elasticity, “the adhesive 20 fits inside the through hole 22. The configuration of “filled in such a manner” is not essential. That is, the adhesive 20 may be in contact with the inner peripheral surface (resin panel 13) of the through hole 22 in a part of the through holes 22 or in a part of each through hole 22. In this case, the highly elastic adhesive 20 is deformed in the through hole 22 as the resin panel 13 expands or contracts, and functions as a cushioning material. In this way, by actively utilizing the properties of the adhesive 20 as an elastic body, the amount management and the filling position management when the adhesive 20 is filled in the through holes 22 provided in the laminated panel 11 can be performed. Simplified.

  Note that the type of the adhesive 20 to be used may be different between the region S1 and the region S2 illustrated in FIG. That is, for the region S1, the support function of the laminated panel 11 by the holder 15 is prioritized using the adhesive 20 having a higher hardness at curing (small elasticity), while the region S2 has higher elasticity than the region S1. You may make it give priority to the function which absorbs the deformation | transformation of the resin panel 13 using the adhesive agent 20, ensuring a support function.

(Third embodiment)
FIG. 8 is an explanatory view showing a support structure for the laminated panel 11 in the vehicle body 1 in the third embodiment of the present invention. In the first and second embodiments, the panel assembly 10 includes the laminated panel 11, the holder 15, and the like and has an independent form, but in the third embodiment, the holder 15 is configured by a part of the vehicle body 1. The point is a feature.

  In 3rd Embodiment, as shown in FIG. 8, the laminated panel 11 is directly attached to the roof side rail 50 which comprises the vehicle body 1, and opening / closing of the laminated panel 11 is not assumed here. A pair of left and right roof side rails 50 are provided on the front and rear of the vehicle body 1, and are a part of a highly rigid vehicle body skeleton in which an upper member 50a and a lower member 50b are integrated by welding. A horizontal surface 50c is provided so as to overlap with the lower member 50b. In the third embodiment, the laminated panel 11 is supported and fixed to the horizontal surface 50c.

  The laminated panel 11 has the same configuration as that described in the first embodiment, and the glass panel 12 and the resin panel 13 are laminated with an adhesive medium 14 interposed therebetween. An extension portion 12a extending further outward from the outer edge is included. This extension part 12a is arrange | positioned in the position facing the horizontal surface 50c formed in the roof side rail 50, and the glass panel 12 is a single layer of the extension part 12a of the laminated panel 11 (namely, laminated panel 11). The adhesive 20 is filled between the portion) and the horizontal surface 50c. The main surface 12 b of the glass panel 12 on the resin panel 13 side is fixed to the horizontal surface 50 c, that is, the roof side rail 50 by the adhesive 20. In the third embodiment, the adhesive 20 also serves as a sealing material that ensures a watertight state between the laminated panel 11 and the roof side rail 50.

  On the further indoor side of the horizontal surface 50c, a holding member 51 is provided spaced apart from the adhesive 20 by a predetermined distance. The holding member 51 corresponds to the regulating member 17 (see FIG. 4) described in the first embodiment, and faces the resin panel 13 (that is, the portion where the glass panel 12 and the resin panel 13 overlap) in the laminated panel 11. It is a member which is provided at a position and holds the laminated panel 11 from below. The holding member 51 is made of an elastic body such as rubber, restricts the mounting position of the laminated panel 11 in the vertical direction, and ensures the strength of the entire support structure against the external force applied to the laminated panel 11. Here, the resin panel 13 is not fixed to the upper surface of the holding member 51, and the resin panel 13 can be displaced relative to the upper surface of the holding member 51 when the resin panel 13 expands or contracts. Has been.

  In order to improve the supporting strength of the laminated panel 11 by the roof side rail 50, it is desirable that the holding member 51 contacts the resin panel 13 and develops a frictional force in the left-right direction. May be provided between the holding member 51 and the resin panel 13. Further, when the resin panel 13 expands or contracts, for example, a fluororesin coating may be provided on the upper surface of the holding member 51 so as not to hinder the deformation, and the resin panel 13 faces the holding member 51. A highly slidable (or self-lubricating) metal film or the like may be formed on the resin panel 13 side.

  Further, as shown in the figure, it is desirable to provide a predetermined gap between the adhesive 20 and the resin panel 13 in the left-right direction. However, in the manufacturing process of the vehicle body 1, as a result of applying the adhesive 20 to the horizontal surface 50 c of the roof side rail 50 to which the holding member 51 is attached and then assembling the laminated panel 11, the adhesive 20 spreads left and right. You may be in the state which contacts the outer edge of the resin panel 13 partially. As described above, a highly elastic adhesive 20 is used. When the resin panel 13 expands, the resin panel 13 is pressed against the adhesive 20 from the side surface. This is because the pressure is absorbed by the adhesive 20.

  As described above, in the third embodiment, the direct connection between the roof side rail 50 and the resin panel 13 constituting the vehicle body 1 is eliminated, and the resin panel 13 expands or contracts due to a change in environmental temperature. Even in such a case, expansion and contraction of the outer edge of the laminated panel 11 can be minimized. As a result, the change in the gap between the roof side rail 50 and the laminated panel 11 (glass panel 12) is reduced, so that the interval δD between the roof side rail 50 and the laminated panel 11 can be reduced as shown in the figure. This improves the appearance of the vehicle body 1 (see FIG. 1). Further, since the linear expansion coefficient of the glass panel 12 is small, excessive shear stress does not act on the adhesive 20 due to expansion or contraction of the glass panel 12.

  As described above, the support structure of the laminated panel 11 according to the third embodiment of the present invention has been described. However, the laminated panel 11 may be attached to other components other than the roof side rail 50. For example, in addition to the roof side rail 50, if the laminated panel 11 is supported by a roof front rail (not shown) or a center frame (not shown) spanned between the roof side rails, these are formed. It is possible to easily provide a fixed sunroof at the vehicle body opening 3 (see FIG. 1).
