Description
[Technical Field]
[0001] FIELD OF THE DISCLOSURE The present disclosure relates to vehicle glazings. [Background technology]
[0002] Conventionally, laminated window panes have been provided with electrical functions and connection elements. The laminated window panes include at least two panes surface-connected to at least one thermoplastic interlayer and at least one electrical function layer disposed between the panes. The laminated window panes further include at least one foil conductor conductively connected to the electrical function layer, the foil conductor extending from the laminated window panes and fixed to the outer side of at least one of the laminated window panes, the foil conductor having a connection point for electrical contact on the outer side of the laminated window panes. The laminated window panes further include at least one housing including at least one power supply line and at least one electrical connection, the housing adhesively bonded or clamped to the outer side of at least one of the panes, the electrical connection of the housing being in electrical contact with the connection point of the foil conductor. At least one pane has an undercut, and the foil conductor extends around the side edge of the undercut pane without overhang. The interior of the housing is sealed from gas, water, or moisture by a sealing means, preferably an acrylic or polyurethane-based adhesive (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Special Publication No. 2013-530916 Summary of the Invention [Problem to be solved by the invention]
[0004] In conventional laminated window glass (vehicle window glass), the interior of the housing is sealed with a sealing means (sealing member). However, the boundary between the two window glass panes (the joint between the two glass panes) and the connection where the power supply line that supplies power from the vehicle body is connected (the connection between the power supply line and the power supply terminal on the vehicle window glass) are not directly sealed, resulting in insufficient sealing at the boundary between the two window glass panes. Furthermore, because the foil conductor is thick, even if the two window glass panes are connected to the thermoplastic intermediate layer in a planar manner, the thickness of the foil conductor creates gaps between the thermoplastic intermediate layer and the side surfaces of the foil conductor. This can compromise the airtightness and watertightness of the joint between the two window glass panes.
[0005] Furthermore, if the process of directly sealing the seam between the two glass plates with a sealing member and the process of directly sealing the connection between the power supply line and the power supply terminal on the vehicle window glass with a sealing member are performed separately, efficient sealing cannot be achieved.
[0006] Therefore, an object of the present invention is to provide a vehicle window glass that can efficiently form a sufficient seal at the joint between two glass sheets and at the connection between the power supply line and the power supply terminal on the vehicle window glass side. [Means for solving the problem]
[0007] a first glass plate having a first main surface, a second main surface, and a first side surface; a second glass plate having a third main surface, a fourth main surface, and a second side surface; and an interlayer film provided between the second main surface and the third main surface, the vehicle window glass being provided in an opening of a vehicle body; a flexible substrate having a first substrate portion provided between the second main surface and the third main surface; and a second substrate portion including a power supply terminal to which a power supply line that supplies power from the vehicle body is connected, the second substrate portion being formed integrally with the first substrate portion and provided across the second side surface and the fourth main surface; a functional member provided between the second main surface and the third main surface, the functional member being supplied with power via the first substrate portion of the flexible substrate; a sealed container having a frame portion that surrounds the second substrate portion at the first side surface, the second side surface, and the fourth main surface; and a sealing member that seals a space surrounded by the first side surface, the second side surface, the fourth main surface, and the frame portion. [Effects of the Invention]
[0008] A vehicle window glass can be provided that can efficiently form a sufficient seal at the joint between the two glass sheets and at the connection portion between the power supply line and the power supply terminal on the vehicle window glass side. [Brief explanation of the drawings]

[0010] <Embodiment> Hereinafter, an embodiment to which the present disclosure is applied will be described. In the following, the same elements will be denoted by the same reference numerals, and duplicated explanations may be omitted.
[0011] In the following description, an XYZ coordinate system is defined. The direction parallel to the X axis (X axis direction), the direction parallel to the Y axis (Y axis direction), and the direction parallel to the Z axis (Z axis direction) are perpendicular to one another. For ease of explanation, the -Z axis direction may be referred to as the lower side or bottom, and the +Z axis direction may be referred to as the upper side or top. Plan view refers to a view from the XY plane, and refers to a plan view of the laminated glass of a vehicle window glass. In the following description, the length, width, thickness, etc. of each part may be exaggerated to make the configuration easier to understand. Terms such as parallel, right angle, orthogonal, horizontal, vertical, top and bottom, etc., are permitted to deviate to the extent that they do not impair the effects of the embodiments.
[0012] Examples of the vehicle window glass in this embodiment include a windshield (front glass) attached to the front of the vehicle, fixed side glass attached to the side of the vehicle, side glass attached to the side of the vehicle and movable relative to the vehicle body, etc. Furthermore, examples of the vehicle window glass in this embodiment include fixed roof glass attached to the ceiling of the vehicle, roof glass attached to the ceiling of the vehicle body and movable relative to the vehicle body, rear glass attached to the rear of the vehicle, etc. The vehicle window glass is not limited to these examples.
[0013] <Vehicle 10 equipped with vehicle window glass 100> FIG. 1 is a diagram showing an example of a vehicle 10 equipped with a vehicle window glass 100. FIG. 1 shows, as an example, approximately half of the rear of a vehicle body 10A of the vehicle 10 from the side. The vehicle body 10A has an opening 11, and the vehicle window glass 100 is provided in the opening 11. The vehicle window glass 100 is, as an example, a side glass that is slidable up and down relative to the vehicle body. In FIG. 1, the vehicle body 10A and the opening 11 are indicated by dashed lines.
[0014] Here, the vehicle 10 is, for example, an automobile such as an EV (Electric Vehicle), a PHEV (Plug-in Hybrid Electric Vehicle), an HV (Hybrid Vehicle), a gasoline vehicle, or a diesel vehicle. The vehicle 10 may also be a train or steam locomotive. The vehicle 10 is an example of a moving body that moves and carries passengers.
[0015] The vehicle window glass 100 shown in FIG. 1 is, as an example, a side glass on the right rear side of a vehicle 10. FIG. 1 shows the vehicle window glass 100 as a side glass on the right rear side when viewed from the interior side of the vehicle 10 in a see-through manner. The vehicle window glass 100 may be provided in a door on the right rear side of the vehicle 10, or, if the vehicle 10 does not have a door at the rear, may be provided on the right rear side of the vehicle body 10A. The vehicle window glass 100 is movable with respect to the door or the vehicle body 10A. In the following description, the vehicle window glass 100 will be described as being slidable in the up and down direction with respect to the vehicle body 10A.
[0016] In this embodiment, the X-axis direction is the front-to-rear direction of the vehicle 10. The Y-axis direction is the up-and-down direction of the vehicle window glass 100, and is the direction in which the vehicle window glass 100 can slide relative to the vehicle body 10A. The +Y-axis direction is the sliding direction for closing the vehicle window glass 100, and the -Y-axis direction is the sliding direction for opening the vehicle window glass 100. As an example, the vehicle window glass 100 is attached in an inclined state relative to the vehicle 10, so the Y-axis direction is inclined with respect to the up-and-down direction, which is the vertical direction in FIG. 1. The Z-axis direction is the direction penetrating the vehicle window glass 100 in the thickness direction. The side of the vehicle window glass 100 in the +Z-axis direction is the exterior side of the vehicle body, and the side of the vehicle window glass 100 in the -Z-axis direction is the interior side of the vehicle body.
[0017] 1 shows the positional relationship of each part when the vehicle window glass 100 is completely closed relative to the vehicle body 10A. The completely closed state of the vehicle window glass 100 relative to the vehicle body 10A refers to a state in which the amount of movement of the vehicle window glass 100 relative to the vehicle body 10A reaches its maximum amount in the +Y axis direction.
[0018] Opening 11 is an opening that appears in vehicle body 10A by opening laminated glass 110, and is completely closed when laminated glass 110 is completely closed to vehicle body 10A. When laminated glass 110 is completely closed to vehicle body 10A, the portion of laminated glass 110 that is below opening 11 is not exposed to opening 11 and is not visible from outside vehicle body 10A.
[0019] A holder 190 is attached to the bottom of the vehicle window glass 100, and a regulator (lifting device) is connected to the holder 190. The vehicle body 10A has a front sash located in the +X-axis direction of the vehicle window glass 100 and a rear sash located in the -X-axis direction, and the vehicle window glass 100 is slidable along the Y-axis direction (the extension direction of the front sash and rear sash) by the driving force of the regulator. The vehicle body 10A also has a belt molding extending in the X-axis direction. The belt molding is provided to remove water, dust, etc. adhering to the vehicle window glass 100 and prevent them from entering the interior of the vehicle body 10A. Note that the regulator that slides the vehicle window glass 100 along the Y-axis direction relative to the vehicle body 10A is omitted here. As an example, the regulator is arranged inside the vehicle body 10A, closer to the interior of the vehicle than the vehicle window glass 100 (on the -Z-axis direction). A holder 190 for connecting the vehicle window glass 100 to a regulator is shown below the vehicle window glass 100 in FIG.
[0020] <Overall configuration of vehicle window glass 100> The vehicle window glass 100 includes a laminated glass 110, an FPC (Flexible Printed Circuit) 120, a light control panel 130, a sealing box 140, a power supply cable 145, and a silicone resin 150. The FPC 120 is an example of a flexible substrate and is a flat harness. The light control panel 130 is an example of a functional member and is a panel whose light transmittance changes. The sealing box 140 is an example of a sealing container. The power supply cable 145 is an example of a power supply line. The silicone resin 150 is an example of a sealing member.
[0021] Here, an embodiment will be described in which the dimming panel 130 is an example of a functional member, but the functional member is not limited to the dimming panel 130. The functional member may be any member that operates with power supplied from the vehicle 10 and performs a predetermined function, and examples of the functional member other than the dimming panel 130 include a heating wire, a conductive film, an antenna, an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode) display, etc. The following description will be made with reference to Figs. 2 to 6C in addition to Fig. 1.
[0022] Fig. 2 is an enlarged view of an example of a portion of the laminated glass 110. Fig. 2 shows a portion of the laminated glass 110 where the FPC 120, the sealing box 140, the power supply cable 145, and the silicone resin 150 are provided.
[0023] Fig. 3 is a diagram showing an example of a state in which the FPC 120 is mounted on the laminated glass 110. Fig. 3 is a further enlarged view of Fig. 2 from which the sealing box 140, the power supply cable 145, and the silicone resin 150 have been removed.
[0024] Fig. 4A is a diagram showing an example of the configuration of a cross section taken along the line AA in Fig. 2. Fig. 4B is a diagram showing an example of the configuration of a cross section taken along the line BB in Fig. 3. Figs. 5A to 5C are views showing the sealed box 140 from the -Z axis direction side. Figs. 6A to 6C are views showing the sealed box 140 from the +Z axis direction side.
[0025] <Laminated Glass 110> 4A and 4B, the laminated glass 110 is formed by bonding a glass plate 111 provided on the exterior side of the vehicle body 10A to a glass plate 112 provided on the interior side of the vehicle body 10A via an intermediate film 113 disposed between the glass plates 111 and 112. In addition, an FPC 120 and a light control panel 130 are provided between the glass plates 111 and 112 of the laminated glass 110.
[0026] As an example, the glass plate 112 is provided on the interior side of the vehicle body 10A, and therefore, hereinafter, as an example, a configuration will be described in which the FPC 120 is bent from between the glass plates 111 and 112 toward the interior side of the vehicle. However, the vehicle window glass 100 is not limited to this configuration, and the glass plate 111 may be provided on the interior side of the vehicle body 10A, and the glass plate 112 may be provided on the exterior side of the vehicle body 10A, and the FPC 120 may be bent from between the glass plates 111 and 112 toward the exterior side.
[0027] <Glass plates 111 and 112> Glass plate 111 is an example of a first glass plate, and glass plate 112 is an example of a second glass plate. Laminated glass 110 is provided so as to be slidable along the Y-axis direction relative to vehicle body 10A. Being slidable along the Y-axis direction relative to vehicle body 10A means being slidable in the up-and-down direction relative to vehicle body 10A.
[0028] The glass plates 111 and 112 are transparent, flat glass plates. The glass plate 111 has an outdoor-facing main surface 111A, an indoor-facing main surface 111B, and a side surface 111C. The main surface 111A is an example of a first main surface, the indoor-facing main surface 111B is an example of a second main surface, and the side surface 111C is an example of a first side surface. The glass plate 112 has an outdoor-facing main surface 112A, an indoor-facing main surface 112B, and a side surface 112C. The main surface 112A is an example of a third main surface, the indoor-facing main surface 112B is an example of a fourth main surface, and the side surface 112C is an example of a second side surface.
[0029] The glass plates 111 and 112 may be inorganic glass or organic glass. Examples of inorganic glass that can be used include, without particular limitation, soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass. Among these, soda-lime glass is particularly preferred from the viewpoints of manufacturing cost and formability. The forming method of the glass plates 111 and 112 is not particularly limited. For example, in the case of inorganic glass, glass plates formed by a float method or the like are preferred.
[0030] When the glass plates 111 and 112 are inorganic glass, they may be either untempered glass or tempered glass. Untempered glass is produced by forming molten glass into a plate shape and slowly cooling it. Tempered glass is produced by forming a compressive stress layer on the surface of untempered glass, and may be either air-cooled tempered glass or chemically tempered glass.
[0031] If the tempered glass is physically tempered glass (e.g., air-cooled tempered glass), the glass surface may be tempered by a process other than slow cooling, such as rapidly cooling a uniformly heated glass sheet from a temperature near its softening point during bending, thereby generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the interior of the glass. If the tempered glass is chemically tempered glass, the glass surface may be tempered after bending by generating compressive stress on the glass surface using an ion exchange method or the like. Furthermore, glass that absorbs ultraviolet or infrared rays may be used as the glass sheets 111 and 112. The glass sheets 111 and 112 are preferably transparent, but may also be colored to the extent that transparency is not impaired.
[0032] The laminated glass 110 may have a curved shape such that the exterior side is convex when attached to the vehicle 10. The laminated glass 110 may have a single-curve shape bent in only one direction, or may have a compound-curve shape bent in two directions (for example, the vertical direction when the laminated glass 110 is attached to the vehicle 10 and the horizontal direction perpendicular to the vertical direction). Gravity forming, press forming, roller forming, or the like is used to bend the laminated glass 110. When the laminated glass 110 is bent to a predetermined curvature, the radius of curvature of the laminated glass 110 may be 1,000 mm or more and 100,000 mm or less.
[0033] Furthermore, when the laminated glass 110 is installed in the vehicle 10, the thickness of the glass plate 111 located on the exterior side and the thickness of the glass plate 112 located on the interior side may be the same or different. The thickness of the glass plate 111 is preferably 1.0 mm or more and 3.0 mm or less. A thickness of 1.0 mm or more of the glass plate 111 provides sufficient strength, such as resistance to flying stones, while a thickness of 3.0 mm or less prevents the laminated glass 110 from becoming too heavy, which is preferable in terms of fuel efficiency of the vehicle 10. The thickness of the glass plate 112 is preferably 0.3 mm or more and 2.3 mm or less. A thickness of 0.3 mm or more of the glass plate 112 provides good handling, while a thickness of 2.3 mm or less prevents the laminated glass 110 from becoming too heavy. The thicknesses of the glass plates 111 and 112 are preferably each 1.8 mm or less, which allows the laminated glass 110 to achieve both lightweight and sound insulation, and is therefore preferable. Note that when the thickness of the glass plate 112 is 1.0 mm or less, the glass plate 112 may be chemically strengthened glass. When the glass plate 112 is a chemically strengthened glass, it is preferable that the compressive stress value of the glass surface is 300 MPa or more, and the depth of the compressive stress layer is 2 μm or more.
[0034] When the glass plates 111 and 112 are made of organic glass, examples of the material for the organic glass include transparent resins such as polycarbonate and acrylic resins (for example, polymethyl methacrylate).
[0035] <Interlayer film 113> The interlayer 113 is a transparent or semi-transparent dielectric material having dielectric properties and interposed between the glass plates 111 and 112 as shown in FIGS. 4A and 4B. The glass plates 111 and 112 are bonded together by the interlayer 113. Examples of materials for the interlayer 113 include thermoplastic polyvinyl butyral (PVB) and ethylene vinyl acetate copolymer (EVA). The interlayer 113 may be transparent or colored. The interlayer 113 may also be composed of two or more layers of film.
[0036] 4A and 4B , in the portion where the dimming panel 130 is present in a plan view, the interlayer film 113 is disposed between the glass plate 111 and the dimming panel 130 and between the dimming panel 130 and the glass plate 112. However, the interlayer film 113 is not limited to this configuration, and may be disposed between the glass plate 111 and the dimming panel 130, but not necessarily between the dimming panel 130 and the glass plate 112. Furthermore, the interlayer film 113 may be disposed between the dimming panel 130 and the glass plate 112, but not necessarily between the glass plate 111 and the dimming panel 130.
[0037] 4A and 4B , in the portion where the FPC 120 is present in plan view, the intermediate film 113 is disposed between the glass plate 111 and the FPC 120 and between the FPC 120 and the glass plate 112. However, the intermediate film 113 is not limited to this configuration, and may be disposed between the glass plate 111 and the FPC 120, but not between the FPC 120 and the glass plate 112. The intermediate film 113 may be disposed between the glass plate 112 and the FPC 120, but not between the FPC 120 and the glass plate 111.
[0038] <fpc120> As shown in FIG. 2, the FPC 120 is provided at the end of the laminated glass 110 on the −Y-axis direction side, and is sealed with a silicone resin 150 while being surrounded by a sealing box 140.
[0039] 4A and 4B , the FPC 120 is located across the −Y axis direction side of the dimming panel 130 and on the main surface 112B of the glass plate 112, is connected to the end of the dimming panel 130 on the −Y axis direction side, and is bent along the side surface 112C at the end of the glass plate 112 in the −Y axis direction. The FPC 120 and the dimming panel 130 may have an overlapping portion between the glass plates 111 and 112, but as an example, the following description will be given assuming that there is no overlapping portion.
[0040] FPC 120 has substrate portion 120A and substrate portion 120B. Substrate portion 120A is an example of a first substrate portion of FPC 120 that is provided between main surface 111B and main surface 112A. Substrate portion 120B is an example of a second substrate portion of FPC 120 that is provided across side surface 112C and main surface 112B. As shown in FIG. 3, substrate portion 120B is T-shaped in a plan view. Note that the shape of substrate portion 120B in a plan view is not limited to a T-shape and may be any shape.
[0041] The FPC 120 has an insulating layer 121, wiring 122, and a power supply terminal 123. The insulating layer 121 is, for example, a flexible substrate made of polyimide. The wiring 122 is, for example, wiring formed by patterning copper foil or the like on the surface of the insulating layer 121, and is provided over the entire substrate portions 120A and 120B. Two power supply terminals 123 are provided near the end of the portion of the FPC 120 located on the main surface 112B of the glass plate 112 on the +Y-axis direction side. Therefore, the substrate portion 120B is provided with the power supply terminals 123. The two power supply terminals 123 are used as a positive terminal and a negative terminal.
[0042] Like the wiring 122, the power supply terminal 123 is formed by patterning a copper foil or the like formed on the surface of the insulating layer 121, and is exposed to the outer surface of the FPC 120 through an opening provided in the insulating layer 121. In FIG. 4A, the thickness of the power supply terminal 123 is exaggerated to make the position of the power supply terminal 123 easier to see, but the thickness of the power supply terminal 123 is, for example, equal to the thickness of the wiring 122. Note that the power supply terminal 123 may be formed thicker than the wiring 122.
[0043] Terminal 145A of power feed cable 145 is connected to power feed terminal 123 by, for example, soldering. Terminal 145A of power feed cable 145 may also be connected to power feed terminal 123 by welding, bonding with a conductive adhesive, or fusing.
[0044] <Dimming Panel 130> The dimming panel 130 is an example of a functional component whose transmittance changes depending on the power supplied via the FPC 120. Here, as an example, a configuration will be described in which the transmittance of the dimming panel 130 changes between two levels, a high state and a low state, depending on whether or not power is supplied via the FPC 120. However, the dimming panel 130 may also be a panel whose transmittance changes depending on the duty ratio of a PWM (Pulse Width Modulation) pulse signal. For example, the dimming panel 130 may be a resin or glass panel to which a dimming device whose transmittance changes depending on the duty ratio of a PWM pulse signal is attached. The dimming device may also be a suspended particle device (SPD), a polymer dispersed liquid crystal (PDLC), a polymer network liquid crystal (PNLC), a guest-host liquid crystal, a photochromic device, an electrochromic device, an electrokinetic device, or the like.
[0045] When the transmittance of the dimming panel 130 changes in two stages, the dimming panel 130 is transparent when the transmittance is high, and changes to an opaque state such as gray when the transmittance is low, and is in a state where it does not transmit much light. When the dimming panel 130 is driven by a PWM pulse signal, the transmittance can be controlled in multiple stages between the transparent state and the opaque state, and as an example, the transmittance of the dimming panel 130 is minimum when the duty ratio of the PWM pulse signal is 0%.
[0046] 1, the light control panel 130 is provided in an area that covers the opening 11 when the laminated glass 110 is completely closed relative to the vehicle body 10A, out of the entire area of the laminated glass 110 in a plan view. This is because the light control panel 130 is arranged in a position that can be seen from both the outside and inside of the vehicle body 10A when the laminated glass 110 is completely closed relative to the vehicle body 10A.
[0047] <Sealing Box 140> 1, 2, and 4A, the sealing box 140 is provided at the end of the laminated glass 110 on the -Y axis direction side. The sealing box 140 has a frame portion 141 and a guide portion 142. The sealing box 140 is adhered to the main surface 112B of the laminated glass 110 with double-sided tape 160 shown in FIGS. 6A to 6C.
[0048] The sealing box 140 is, for example, a resin molded product made of polybutylene terephthalate (PBT) or ABS resin (a copolymer synthetic resin of acrylonitrile, butadiene, and styrene).
[0049] <Frame 141> 2 and 4A, the frame portion 141 is provided so as to surround the FPC 120. More specifically, the frame portion 141 is a frame-shaped portion that surrounds the substrate portion 120B on the side surface 111C of the glass plate 111 and the main surface 112B and the side surface 112C of the glass plate 112, and further extends along the main surface 111A of the glass plate 111.
[0050] The frame portion 141 is provided to seal the first portion 101A shown in FIGS. 2 and 4A and the second portion 101B shown in FIG. 4A by filling the space between the frame portion 141 and the laminated glass 110 with silicone resin 150. The first portion 101A (see FIGS. 2 and 4A) is a portion where a terminal 145A of a power supply cable 145 is connected to a power supply terminal 123 of the FPC 120 on a main surface 112B of the glass plate 112. The second portion 101B (see FIG. 4A) is a portion where the FPC 120 is exposed from the joint between the glass plates 111 and 112 of the laminated glass 110.
[0051] Frame 141 has base 141A, extending portion 141B, overlapping portion 141C, opening 141D, opening 141E, hole 141F, protruding portion 141G, and convex portion 141H. Opening 141D is an example of a first opening, and opening 141E is an example of a second opening.
[0052] The base portion 141A and the extension portion 141B are formed by wall-like members provided on the side surface 111C of the glass plate 111 and the main surface 112B and side surface 112C of the glass plate 112, and surround the substrate portion 120B.
[0053] The base 141A is a portion of the frame 141 that is located on the -Z-axis direction side of the main surface 112B in the Z-axis direction. The base 141A is provided on the main surface 112B so as to surround the FPC 120 that is T-shaped in a plan view, and the end portion on the -Y-axis direction side extends further toward the -Y-axis direction than the main surface 112B in a plan view. A portion of the base 141A that overlaps with the main surface 112B in a plan view is in contact with the main surface 112B. The base 141A surrounds the first portion 101A (see FIGS. 2 and 4A) on the main surface 112B.
[0054] In a plan view, base portion 141A surrounds the outer side of a portion of FPC 120 that is located on main surface 112B. Base portion 141A is open on a +Z axis direction side and a -Z axis direction side. The opening on the +Z axis direction side of base portion 141A is part of opening 141D. The opening on the -Z axis direction side of base portion 141A is opening 141E.
[0055] Since the opening 141E is provided over the entire −Z-axis direction side of the frame 141 of the sealed box 140, it is easy to fill with the silicone resin 150 and the height of the sealed box 140 in the Z direction can be reduced. However, the frame 141 of the sealed box 140 may have a member such as a lid that covers the opening 141E. In this case, an opening or a hole for filling with the silicone resin 150 may be provided in a part of the lid.
[0056] The extending portion 141B is a portion of the frame portion 141 that extends further in the +Z-axis direction than the main surface 112B and faces the side surfaces 112C and 111C. The extending portion 141B is located between the base portion 141A and the overlapping portion 141C, and extends toward the +Z-axis direction from a portion of the base portion 141A that extends further in the -Y-axis direction than the main surface 112B. The extending portion 141B is not in contact with the laminated glass 110, but is held by the base portion 141A. The extending portion 141B surrounds the periphery of the second portion 101B (see FIG. 4A).
[0057] The overlapping portion 141C is a plate-shaped portion that extends in the +Y-axis direction from the end of the extending portion 141B on the +Z-axis direction side and overlaps with the main surface 111A of the glass plate 111. The overlapping portion 141C is not in contact with the laminated glass 110, and is held by the base portion 141A via the extending portion 141B. The overlapping portion 141C is disposed with a gap G1 (see FIG. 4A) between it and the main surface 111A.
[0058] 4A, the base 141A, the extension 141B, and the overlapping portion 141C are configured to have a C-shape in a cross section parallel to the YZ plane, and the end of the laminated glass 110 in the -Y-axis direction is inserted into the C-shape. By providing the overlapping portion 141C, when the silicone resin 150 is filled with the base 141A facing upward, the silicone resin 150 passes between the extension 141B and the side surfaces 112C and 111C, and also fills between the main surface 111A and the overlapping portion 141C. By filling the silicone resin 150 also between the main surface 111A of the laminated glass 110 and the overlapping portion 141C in this way, the sealing box 140 and the silicone resin 150 can be more firmly fixed to the laminated glass 110.
[0059] The reason for providing the gap G1 is to ensure that the end of the laminated glass 110 in the -Y-axis direction can be inserted reliably, taking into consideration manufacturing errors of the laminated glass 110 and the sealing box 140, with the main surface 112B of the laminated glass 110 in contact with the end surface of the base 141A on the +Z-axis direction side. The gap G1 is, for example, approximately 0.4 mm. The gap G1 is preferably not limited to 0.4 mm, but is preferably a value that takes into consideration the thickness tolerance of the glass 110.
[0060] The opening 141D is located on a first side of the frame 141 that is closer to the laminated glass 110. The first side is the side of the frame 141 on which the side surface 111C of the glass plate 111 and the main surface 112B and side surface 112C of the glass plate 112 are located. The opening 141D opens along an end of the base 141A on the +Z-axis direction side, a portion of the extending portion 141B that extends in the Z direction facing the side surfaces 112C and 111C, ends of the overlapping portion 141C on the ±X-axis direction sides, and an end of the overlapping portion 141C on the +Y-axis direction side.
[0061] Opening 141E is located on a second side of frame 141 that is farther from laminated glass 110. The second side is the -Z direction side of frame 141. Opening 141E opens the entire -Z axis direction side of frame 141 along the end of base 141A on the -Z axis direction side. Opening 141E opens in a T-shape in plan view, with a gap between it and the portion of FPC 120 that is located on main surface 112B, so as to surround the outside of the portion of FPC 120 that is located on main surface 112B.
[0062] When not filled with silicone resin 150, opening 141E exposes the entire portion of FPC 120 that is surrounded by base 141A in a plan view. However, opening 141E may be smaller. For example, opening 141E may be an opening that opens only above a portion of FPC 120 that is located on main surface 112B, or may be an opening that opens above two power supply terminals 123. Opening 141E only needs to be open above at least first portion 101A. In these cases, a wall or a lid may be provided on the portion of frame 141 other than opening 141E on the −Z-axis direction side. This is because if the top of first portion 101A is open, it is easy to fill first portion 101A with silicone resin 150 and it is easy to visually confirm that first portion 101A is sealed with silicone resin 150.
[0063] Hole 141F is provided across extending portion 141B and overlapping portion 141C and is a hole that penetrates extending portion 141B and overlapping portion 141C. When filling the gap between frame portion 141 and laminated glass 110 with silicone resin 150, as shown in FIG. 2, sealing box 140 is bonded to laminated glass 110, and laminated glass 110 and sealing box 140 are arranged with the -Z axis direction side facing up, and silicone resin 150 is filled in this state. In this state, hole 141F is located on the lower end side of sealing box 140, and therefore hole 141F is provided at the end of sealing box 140 on the +Z axis direction side so that it can be visually confirmed through hole 141F whether silicone resin 150 has been filled up to the lower side of extending portion 141B. It should be noted that even if hole portion 141F is not provided, frame portion 141 does not have to have hole portion 141F if, for example, it is possible to visually confirm whether silicone resin 150 has been filled up to the underside of extension portion 141B from the gap between overlapping portion 141C and main surface 111A.
[0064] 5A to 5C and 6A to 6C, the protrusions 141G are provided at corners of portions of the opening 141D of the frame 141 that are located at the lower end of the base 141A, so as to protrude inward beyond the inner wall 141A1 of the base 141A of the frame 141. As an example, the protrusions 141G have an arc-like shape that connects the ends on the +Z axis direction side of the four corners where the inner wall 141A1 is bent at right angles in a plan view. When the silicone resin 150 is filled, the protrusions 141G catch on the silicone resin 150 on the −Z axis direction side of the protrusions 141G, making it difficult for the base 141A to come off the silicone resin 150 and serving to lock the sealed box 140 so as not to come off. Therefore, the protrusion 141G is provided at the end of the inner wall 141A1 of the base 141A on the +Z-axis direction side in the Z-axis direction, and the inner wall 141A1 extends further to the -Z-axis direction side than the protrusion 141G.
[0065] Note that protrusion 141G is not limited to being provided at the end of inner wall 141A1 on the +Z-axis direction side, and may be provided closer to opening 141D than opening 141E in the Z-axis direction. Providing protrusion 141G closer to opening 141D than opening 141E in the Z-axis direction means that inner wall 141A1 is located on the −Z-axis direction side of protrusion 141G, and silicone resin 150 is provided on the −Z-axis direction side of protrusion 141G. This is because protrusion 141G gets caught on silicone resin 150 on the −Z-axis direction side of protrusion 141G, making it difficult for base 141A to come off silicone resin 150.
[0066] The convex portion 141H is a protrusion that protrudes inward from the inner wall 141A1 of the base portion 141A, and is provided for alignment with the outer edge of the FPC 120 when the base portion 141A of the sealing box 140 is placed on the main surface 112B and installed to surround the FPC 120.
[0067] Note that, although a configuration in which the frame portion 141 has the overlapping portion 141C will be described here, the frame portion 141 does not necessarily have to have the overlapping portion 141C. Since the overlapping portion 141C protrudes in the +Z axis direction beyond the main surface 111A of the laminated glass 110, if the sealing box 140 is to not protrude in the +Z axis direction beyond the main surface 111A of the laminated glass 110, the frame portion 141 may be configured not to have the overlapping portion 141C, and the end of the extension portion 141B on the +Z axis direction and the main surface 111A may be aligned in height. In this case, the hole 141F may be provided at the end of the extension portion 141B on the +Z axis direction. A configuration in which the sealing box 140 does not protrude in the +Z axis direction beyond the main surface 111A of the laminated glass 110 is particularly effective, for example, when the vehicle window glass 100 is used as a windshield or roof glass of the vehicle 10.
[0068] <Guide part 142> The guide portion 142 extends toward the +X-axis direction from the end portion on the +X-axis direction side of the -Y-axis direction side of the frame portion 141 along the boundary between the main surface 112B and the side surface 112C. More specifically, the guide portion 142 is slightly curved in plan view to follow the curved shapes of the main surface 112B and the side surface 112C of the laminated glass 110.
[0069] The guide portion 142 has a holding portion 142A that protrudes toward the +Y-axis direction. As shown in Fig. 2, Fig. 5A to Fig. 5C, and Fig. 6A to Fig. 6C, the guide portion 142 has, as an example, three holding portions 142A. As shown in Fig. 2, the holding portions 142A are provided to hold the power supply cable 145.
[0070] The three holding portions 142A are provided at equal intervals along the extension direction of the guide portion 142, and the central holding portion 142A is offset in the +Z axis direction from the two holding portions 142A at both ends. For example, the offset amount of the central holding portion 142A in the +Z axis direction from the two holding portions 142A at both ends is preferably less than the thickness of the power feed cable 145, and more preferably equal to or less than half the thickness of the power feed cable 145. By passing the power feed cable 145 through the +Z axis direction sides of the two holding portions 142A at both ends and the −Z axis direction side of the central holding portion 142A, the three holding portions 142A can sandwich the +Z axis direction side of the side of the power feed cable 145 and the −Z axis direction side of the side of the power feed cable 145, thereby making it possible to stably hold the power feed cable 145. The +Z-axis direction side of the side surface of the power feed cable 145 is an example of a first side of the side surface of the power feed cable 145, and the −Z-axis direction side of the side surface of the power feed cable 145 is an example of a second side of the side surface of the power feed cable 145. Although it is preferable that there are three or more such holding portions 142A, any number of two or more holding portions 142A may be used.
[0071] 5A to 5C and 6A to 6C as long as it can hold the power supply cable 145. For example, the holding portion 142A may be a groove into which the power supply cable 145 is fitted, or a bracket, etc. Furthermore, the guide portion 142 may not have the holding portion 142A. For example, when the guide portion 142 is fixed to the guide portion 142 by double-sided tape or another member, the guide portion 142 does not have to have the holding portion 142A.
[0072] Furthermore, the sealing box 140 may not have the guide portion 142. For example, in a configuration in which it is not necessary to hold the power supply cable 145, or in a case in which the power supply cable 145 is fixed to the laminated glass 110 by a bracket, double-sided tape, or other member, the sealing box 140 may not have the guide portion 142.
[0073] <Power Supply Cable 145> The power feed cable 145 is two wire harnesses connected to the two power feed terminals 123, and is provided to supply DC power from a power source such as a battery of the vehicle 10 to the light control panel 130. As an example, as shown in Fig. 2, a metal terminal 145A is attached to the end of the power feed cable 145. The terminal 145A has a U-shaped tab 145A1 as shown in Fig. 2, and is fixed to the power feed cable 145 by crimping the tab 145A1.
[0074] The power feed cable 145 is connected to the power feed terminal 123 by connecting the terminal 145A to the power feed terminal 123. The terminal 145A is connected to the power feed terminal 123 by soldering, for example, but may also be connected by welding, bonding with a conductive adhesive, or fusing. Alternatively, the lead wire of the power feed cable 145 may be directly connected to the power feed terminal 123 by soldering or the like, without using the terminal 145A. That is, the end of the lead wire of the power feed cable 145 may be used as the terminal.
[0075] <Silicone resin 150> Silicone resin 150 is filled into the space surrounded by side surface 111C, side surface 112C, main surface 112B, and main surface 111A of laminated glass 110 and sealing box 140, and seals the space. More specifically, silicone resin 150 seals first portion 101A shown in Figures 2 and 4A and second portion 101B shown in Figure 4A. Silicone resin 150 is a silicone sealer, and is a liquid adhesive.
[0076] Since the first part 101A and the second part 101B are surrounded by the sealing box 140, by filling the space surrounded by the sealing box 140 and the side surface 111C, the side surface 112C, the main surface 112B, and the main surface 111A of the laminated glass 110 with silicone resin 150, it is possible to seal both the first part 101A and the second part 101B in a single sealing operation.
[0077] <Double-sided tape 160> 6A to 6C, the double-sided tape 160 is adhered to the surfaces on the +Z axis direction side of the base portion 141A and the guide portion 142. The sealing box 140 is adhered to the main surface 112B of the laminated glass 110 by the double-sided tape 160, and is fixed to the laminated glass 110.
[0078] <Comparison of manufacturing times of the vehicle window glass 100 according to the embodiment and a comparative vehicle window glass> The comparative vehicle window glass has a configuration in which the sealing box 140 is omitted from the vehicle window glass 100 of the embodiment. In the comparative vehicle window glass, the first portion 101A and the second portion 101B are sealed in separate sealing operations. For the second portion 101B, the glass plates 111 and 112 are bonded with the interlayer film 113 with the FPC 120 and the light control panel 130 sandwiched between them, and then the second portion 101B is sealed with a sealing member. Then, for the first portion 101A, after the sealing operation for the second portion 101B is completed, the terminal 145A of the power supply cable 145 is connected to the power supply terminal 123 with solder or the like, and then the first portion 101A is sealed with the sealing member. In this way, the comparative vehicle window glass is sealed in two stages. In contrast, the vehicle window glass 100 of the embodiment uses the sealing box 140, which allows the first portion 101A and the second portion 101B to be sealed simultaneously in a single sealing operation, thereby enabling the vehicle window glass 100 to be manufactured efficiently.
[0079] In an experiment on a comparative vehicle window glass, the first sealing operation for the second portion 101B took 30 seconds, followed by 20 seconds for drying and testing the sealing material used in the first sealing operation. The second sealing operation for the first portion 101A took 35 seconds to seal with the sealing material using the frame member.
[0080] In contrast, in an experiment on the vehicle window glass 100 of the embodiment, the time required for simultaneously performing the sealing operation on the first portion 101A and the second portion 101B using the sealing box 140 was 55 seconds. Thus, it was found that the time required for the sealing operation on the vehicle window glass 100 of the embodiment can be significantly reduced compared to the 85 seconds required for two sealing operations on the comparative vehicle window glass. Furthermore, by combining the work steps into one, the risk of damage to the FPC 120, such as a break in the wire, during the operation can be reduced. In the first sealing operation, which seals only the second portion 101B, there is a risk that the nozzle discharging the silicone resin 150 will hit the FPC 120, causing damage such as a break in the wire. However, by simultaneously performing the sealing operation on the first portion 101A and the second portion 101B using the sealing box 140, the possibility of the nozzle hitting the second portion 101B is reduced, thereby reducing the risk of damage to the FPC 120.
[0081] <Effects> As described above, the vehicle window glass 100 includes the glass plate 111 having the main surface 111A, the main surface 111B, and the side surface 111C, the glass plate 112 having the main surface 112A, the main surface 112B, and the side surface 112C, and the interlayer film 113 provided between the main surface 111B and the main surface 112A, and is provided in the opening 11 of the vehicle body 10A. The vehicle window glass 100 also includes the FPC 120 having the substrate portion 120A provided between the main surface 111B and the main surface 112A, and the substrate portion 120B provided across the side surface 112C and the main surface 112B and including the power supply terminal 123 to which the power supply cable 145 to which power is supplied from the vehicle body 10A is connected, and which is formed integrally with the substrate portion 120A. The vehicle window glass 100 also includes a light control panel 130 that is provided between the main surface 111B and the main surface 112A and to which power is supplied via the substrate portion 120A of the FPC 120. The vehicle window glass 100 also includes a sealing box 140 that has a frame portion 141 that surrounds the substrate portion 120B on the side surface 111C, the side surface 112C, and the main surface 112B, and a silicone resin 150 that seals a space surrounded by the side surface 111C, the side surface 112C, the main surface 112B, and the frame portion 141. Therefore, the first portion 101A (see Figures 2 and 4A) where the terminal 145A of the power supply cable 145 is connected to the power supply terminal 123 of the FPC 120 on the main surface 112B of the glass plate 112, and the second portion 101B (see Figure 4A) where the FPC 120 is exposed from the joint between the glass plates 111 and 112 of the laminated glass 110 can be sealed simultaneously in a single sealing operation.
[0082] Therefore, it is possible to provide a vehicle window glass 100 that can efficiently form a sufficient seal at the joint between the two glass plates 111 and 112 and at the connection between the power supply cable 145 and the power supply terminal 123 on the vehicle window glass 100 side.
[0083] Furthermore, since the main surface 112B faces the interior of the vehicle body 10A, the sealing box 140 and the silicone resin 150 are positioned on the interior side, thereby realizing a configuration that makes it easy to protect the first portion 101A and the second portion 101B from water, dust, etc.
[0084] Furthermore, power supply terminal 123 is provided on at least a part of the portion of substrate portion 120B that overlaps with main surface 112B, and frame portion 141 has opening 141D located on a first side of frame portion 141 that is closer to laminated glass 110 and opening 141E located on a second side of frame portion 141 that is farther from laminated glass 110, and opening 141E surrounds power supply terminal 123 in a plan view of laminated glass 110. In this way, opening 141E surrounding power supply terminal 123 in a plan view makes it easier to fill silicone resin 150 into first portion 101A including power supply terminal 123 and to visually confirm whether silicone resin 150 has been filled into first portion 101A.
[0085] Furthermore, the power supply terminal 123 is provided on at least a part of the portion of the substrate portion 120B that overlaps with the main surface 112B, and the frame portion 141 has an opening 141D located on a first side of the frame portion 141 that is closer to the laminated glass 110 and an opening 141E located on a second side of the frame portion 141 that is farther from the laminated glass 110, and the opening 141E surrounds the substrate portion 120B in a plan view of the laminated glass 110. In this way, since the opening 141E surrounds the substrate portion 120B in a plan view, it is easy to fill the first portion 101A and the second portion 101B with the silicone resin 150 and to visually confirm whether the first portion 101A and the second portion 101B are filled with the silicone resin 150.
[0086] Furthermore, the frame 141 is provided closer to the opening 141D than the opening 141E in the overlapping direction of the glass plate 111, the interlayer 113, and the glass plate 112, and has a protrusion 141G that protrudes inward beyond the inner wall of the frame 141 in a plan view of the laminated glass 110. Therefore, the protrusion 141G catches on the silicone resin 150 on the −Z axis direction side of the protrusion 141G, thereby realizing a configuration in which the sealing box 140 is less likely to come off the silicone resin 150.
[0087] Furthermore, opening 141D is provided across side surface 111C, side surface 112C, and main surface 112B. Therefore, the portions of FPC 120 that are exposed on main surface 112B and side surface 112C are surrounded by frame 141, thereby realizing a configuration in which first portion 101A and second portion 101B can be reliably sealed with silicone resin 150.
[0088] Moreover, frame 141 has base 141A provided along main surface 112B, and extending portion 141B extending from an end of base 141A on the side surface 112C side along side surface 112C and side surface 111C. Therefore, base 141A and extending portion 141B surround first portion 101A and second portion 101B, thereby realizing a configuration in which first portion 101A and second portion 101B can be reliably sealed with silicone resin 150.
[0089] Moreover, frame 141 further has hole 141F penetrating extending portion 141B. Therefore, when silicone resin 150 is filled with base 141A positioned upward, it is possible to check through hole 141F whether silicone resin 150 has been filled up to the underside of extending portion 141B.
[0090] Furthermore, the frame 141 has a base 141A provided along the main surface 112B, an extending portion 141B extending from the side surface 112C side of the base 141A along the side surface 112C and the side surface 111C, and an overlapping portion 141C extending from the end of the extending portion 141B on the main surface 111A side along the main surface 111A and overlapping with the main surface 111A. When the silicone resin 150 is filled with the base 141A facing upward, the silicone resin 150 is also filled between the main surface 111A and the overlapping portion 141C. Therefore, a configuration can be realized in which the first portion 101A and the second portion 101B are surrounded by the base 141A and the extending portion 141B, and the first portion 101A and the second portion 101B can be reliably sealed with the silicone resin 150. Furthermore, by filling the silicone resin 150 between the main surface 111A of the laminated glass 110 and the overlapping portion 141C, the sealing box 140 and the silicone resin 150 can be fixed to the laminated glass 110 more firmly.
[0091] Furthermore, the frame portion 141 is provided across the extending portion 141B and the overlapping portion 141C and has a hole portion 141F penetrating the extending portion 141B and the overlapping portion 141C, so that it is easy to visually check through the hole portion 141F whether the silicone resin 150 has also filled between the main surface 111A of the laminated glass 110 and the overlapping portion 141C.
[0092] The sealing box 140 further has a guide portion 142 that extends from a side portion of the frame portion 141 along the main surface 112B and guides a power supply cable 145 connected to the power supply terminal 123 along the main surface 112B. When the vehicle window glass 100 slides up and down relative to the vehicle body 10A, the power supply cable 145 can be prevented from coming into contact with the vehicle body 10A and being damaged, making it possible to provide a vehicle window glass 100 with improved electrical reliability.
[0093] Furthermore, since the guide portion 142 extends along the boundary between the main surface 112B and the side surface 112C, the power supply cable 145 can be held along the edge of the laminated glass 110 (the boundary between the main surface 112B and the side surface 112C), which makes it possible to more effectively prevent damage to the power supply cable 145 and provide a vehicle window glass 100 with further improved electrical reliability.
[0094] Furthermore, the guide portion 142 has holding portions 142A that are provided along the extension direction of the power feed cable 145 and that alternately hold a first side (+Z axis direction side) and a second side (-Z axis direction side) opposite to the first side of the power feed cable 145. Therefore, with a simple configuration, the power feed cable 145 can be more reliably held, damage to the power feed cable 145 can be more effectively suppressed, and the vehicle window glass 100 with further improved electrical reliability can be provided.
[0095] In the above, a configuration has been described in which the glass plate 112 is provided on the interior side of the vehicle body 10A, and the FPC 120 is bent from between the glass plates 111 and 112 toward the interior side. However, the glass plate 112 may be provided on the exterior side of the vehicle body 10A, and the FPC 120 may be bent from between the glass plates 111 and 112 toward the exterior side. In this case, particularly when the vehicle window glass 100 is attached to a door as a side glass, the weight of the sealing box 140, the power supply cable 145, the silicone resin 150, and the like is applied to the laminated glass 110 when the door is closed. This makes it possible to realize a configuration in which the sealing box 140, the power supply cable 145, the silicone resin 150, and the like are less likely to come off the laminated glass 110.
