Description

[Technical field]

[0001] The present invention relates to a vehicle window glass, and more particularly to a vehicle window glass provided with a component unit used for mounting a vehicle component. [Background technology]

[0002] In recent years, for the purpose of driving assistance, optical devices such as FIR (Far Infrared Rays) cameras, LiDAR (Light Detection And Ranging), radar, and optical sensors that acquire information about the surroundings of a vehicle are being mounted on the inner surface of vehicle window glass such as a windshield of a vehicle. In addition, component units for mounting these optical devices on vehicle window glass are being developed.

[0003] However, vehicle window glass is usually a laminated glass made of two glass sheets, and there is a problem that the intensity of near infrared rays and far infrared rays used in FIR cameras, LiDAR, etc. is attenuated by the glass. Therefore, a proposal has been made to change the two pieces of glass to glass that easily transmits infrared rays. However, if the two pieces of glass are changed to glass that easily transmits infrared rays, there is a problem that the interior of the vehicle becomes too hot. Patent Document 1 describes that a cutout portion is provided by cutting out at least a part of one side of the two pieces of laminated glass toward the center in order to install an optical device, and an IR lens is provided in the cutout portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US Patent Application Publication No. 2021 / 0060906 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, the IR lens is attached to the cutout of the laminated glass using a subframe, and a step is created on the outer surface and the inner surface of the vehicle window glass at the joint between the subframe and the vehicle window glass. Therefore, for example, when applying a urethane sealant to the inner surface of the vehicle window glass so as to go around the periphery of the vehicle window glass in order to attach the vehicle window glass to a vehicle, there is a problem that the step makes it difficult to work. In other words, there is a possibility that the vehicle window glass may be difficult to handle.

[0006] In view of the above problems, an object of the present invention is to provide a vehicle window glass that suppresses attenuation of the intensity of light used in an optical device mounted in a vehicle and is easier to handle even while including a component unit. [Means for solving the problem]

[0007] A vehicle window glass according to one embodiment of the present invention comprises a laminated glass in which two glass sheets are bonded together with an intermediate film therebetween, and a component unit to which a vehicle component including at least an optical device can be attached to a portion of the peripheral edge of the laminated glass, wherein when the laminated glass is attached to a vehicle, at least the interior glass sheet located on the interior side of the vehicle is cut out at a portion of the peripheral edge of the laminated glass where the component unit is to be disposed, and the component unit has a shape such that the interior surface of the laminated glass and the interior surface of the component unit are flush with each other, at least in an area that is a boundary between the laminated glass and the component unit and where an adhesive is applied to attach the vehicle window glass to the vehicle.

[0008] In the above-mentioned vehicle window glass, the component unit is a peripheral portion of the vehicle window glass, and in a region that contributes to mounting the vehicle window glass to the vehicle, the vehicle inside surface and the vehicle outside surface of the vehicle window glass have a step. No It may have a shape.

[0009] In the above-mentioned vehicle window glass, the component unit may be configured such that the optical device is attached to a wiper wiping area of ​​the vehicle window glass.

[0010] In the above-mentioned vehicle window glass, the interior side glass sheet of the laminated glass may be cut out at a portion of the peripheral edge of the laminated glass where the component unit is to be arranged, and the component unit may comprise a plate-shaped member adhered to the interior side surface of the exterior side glass sheet located on the exterior side of the laminated glass, and the plate-shaped member may have an area covering the cut-out portion of the interior side glass sheet of the laminated glass.

[0011] In the above-mentioned vehicle window glass, both the interior side glass sheet and the exterior side glass sheet of the laminated glass are cut out at portions of the peripheral edge of the laminated glass where the component unit is to be arranged, the component unit comprises a plate-shaped member that can fit into the cut-out portion of the laminated glass, and the plate-shaped member may have a shape such that, at the boundary between the laminated glass and the plate-shaped member, the exterior side surface of the laminated glass and the exterior side surface of the plate-shaped member are flush with each other.

[0012] In the above-described vehicle window glass, the plate-shaped member is reinforced glass capable of transmitting infrared rays, and the component unit includes a reinforcing plate that lines an interior surface of the reinforced glass and an interior surface of the laminated glass at a boundary between the reinforced glass and the laminated glass, and the reinforced glass, the laminated glass, and the reinforcing plate may be joined together with an adhesive.

[0013] In the vehicle window glass described above, the component unit may further include a shielding layer formed on an interior surface of the strengthened glass excluding at least a portion corresponding to an optical path of the optical instrument.

[0014] In the vehicle window glass described above, the plate-shaped member may be formed using a resin, and at least a portion of the plate-shaped member corresponding to an optical path of the optical device may be formed from a resin that is transmissive to infrared rays.

[0015] In the above vehicle window glass, the portion of the plate-shaped member other than the portion formed from the resin capable of transmitting infrared light may be formed from a colored resin.

[0016] In the above vehicle window glass, a portion of the plate-shaped member other than the portion made of the resin capable of transmitting infrared light may be made of metal.

[0017] In the above-mentioned vehicle window glass, the portion formed from the infrared ray permeable resin may have a shape such that, at the boundary with the portion formed from the metal, the vehicle exterior surface of the portion formed from the infrared ray permeable resin and the vehicle exterior surface of the portion formed from the metal are flush with each other. Effect of the Invention

[0018] According to the present invention, it is possible to provide a vehicle window glass which suppresses attenuation of the intensity of light used in an optical device mounted in a vehicle and which is easier to handle even though it includes a component unit.

[Diagram 5] FIG. 11 is a cross-sectional view for explaining a vehicle window glass according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, the term "approximately" attached to a shape means a shape that has been partially changed, such as a chamfered shape with rounded corners, a shape with part of the shape missing, or a shape with an arbitrary small shape added to the shape. In this specification, unless otherwise specified, "up and down," "left and right," and "length and width" refer to "up and down," "left and right," and "length and width" as seen by an occupant of a vehicle in which the vehicle window glass is installed.

[0021] First embodiment FIG. 1 is a perspective view for explaining a vehicle window glass 1 according to the first embodiment. FIG. 2 corresponds to a cross-sectional view of the vehicle window glass 1 cut along the cutting line II-II in FIG. 1, and is a cross-sectional view seen from the left side of the vehicle. The vehicle window glass 1 according to the present embodiment may have any shape suitable for mounting to a vehicle, and in the example shown in FIG. 1, is formed into a substantially trapezoidal shape in a plan view. Note that the shape of the vehicle window glass 1 shown in FIG. 1 is one example, and in the present embodiment, the vehicle window glass may have a shape other than that shown in FIG. The vehicle window glass 1 includes a laminated glass 10 and a component unit 11 for mounting vehicle components including optical devices to a part of the peripheral portion of the laminated glass 10.

[0022] As shown in FIG. 2, the vehicle window glass 1 may be provided with a resin mold 12 on the outermost side of the peripheral edge portion of the vehicle window glass 1.

[0023] The resin mold 12 is attached, for example, by a known double-sided tape or adhesive to the upper edge of the vehicle window glass 1. Examples of materials for the mold 12 include synthetic resins such as olefin thermoplastic elastomer (TPO), polyvinyl chloride (PVC), and thermoplastic elastomer (TPE).

[0024] As shown in FIG. 2, when the vehicle window glass 1 is attached to the body panel 60 of the vehicle, a urethane sealant 50 is applied as an adhesive to the vehicle-interior surface of the peripheral portion of the vehicle window glass 1. Specifically, the urethane sealant 50 is applied to a position on the vehicle-interior surface of the vehicle window glass 1 that is inside the mold 12 so as to go around the peripheral portion of the vehicle window glass 1. The vehicle window glass 1 and the metal body panel 60 are then bonded via the urethane sealant 50. At that time, the mold 12 abuts against the body panel 60. The mold 12 prevents the urethane sealant 50 from being visible from the outside of the vehicle, so that the design of the vehicle window glass 1 and the vehicle to which the vehicle window glass 1 is attached can be improved. In addition, if a gap is generated at the attachment point between the vehicle window glass 1 and the body panel 60, wind and rain that enter through the gap during driving, etc., can be prevented from entering the inside of the vehicle by the mold 12 and the urethane sealant 50. A primer for glass may be applied between the vehicle window glass 1 and the urethane sealant 50 in order to promote adhesion between the vehicle window glass 1 and the urethane sealant 50. A primer for painted surfaces or a primer for resin may be applied between the body panel 60 and the urethane sealant 50 in order to promote adhesion between the body panel 60 and the urethane sealant 50.

[0025] As shown in Fig. 2, the laminated glass 10 is formed by bonding two glass sheets 101, 102 together. Specifically, the laminated glass 10 is formed by bonding an interior glass sheet 101, which is located on the interior side of the vehicle, and an exterior glass sheet 102, which is located on the exterior side of the vehicle, via an interlayer 103 when the laminated glass 10 is installed in a vehicle. The laminated glass 10 may also have a shielding layer on at least one of the peripheral portion of the interior surface of the interior glass sheet 101 and the peripheral portion of the interior surface of the exterior glass sheet 102. In the example shown in Fig. 1, a shielding layer 104 is formed on the peripheral portion of the interior surface of the interior glass sheet 101.

[0026] The glass plates 101 and 102 may be inorganic glass or organic glass. As the inorganic glass, for example, soda lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, quartz glass, etc. can be used without any particular limitation. Among these, soda lime glass is particularly preferable from the viewpoint of manufacturing cost and formability. The forming method of the glass plates 101 and 102 is not particularly limited. For example, in the case of inorganic glass, a glass plate formed by a float method or the like is preferable.

[0027] When the glass plates 101 and 102 are inorganic glass, they may be either untempered glass or tempered glass. Untempered glass is made by forming molten glass into a plate shape and slowly cooling it. Tempered glass is made by forming a compressive stress layer on the surface of untempered glass, and may be either air-cooled tempered glass or chemically tempered glass.

[0028] When the tempered glass is physically tempered glass (for example, air-cooled tempered glass), the glass surface may be tempered by generating a compressive stress layer on the glass surface by a temperature difference between the glass surface and the inside of the glass by an operation other than slow cooling, such as quenching a glass sheet uniformly heated in bending from a temperature near the softening point. When the tempered glass is chemically tempered glass, the glass surface may be tempered by generating a compressive stress on the glass surface by an ion exchange method or the like after bending. In addition, glass that absorbs ultraviolet rays or infrared rays may be used as the glass sheets 101 and 102. The glass sheets 101 and 102 are preferably transparent, but may be colored glass sheets to the extent that transparency is not impaired.

[0029] The laminated glass 10 may have a curved shape such that the vehicle exterior side is convex when the laminated glass 10 is installed in a vehicle. The laminated glass 10 may have a single curved shape bent in only one direction, or may have a complex curved shape bent in two directions (for example, the vertical direction when the laminated glass 10 is installed in a vehicle and the horizontal direction perpendicular to the vertical direction). Gravity forming, press forming, roller forming, or the like is used for bending the laminated glass 10. When the laminated glass 10 is bent to a predetermined curvature, the radius of curvature of the laminated glass 10 may be 1000 mm or more and 100000 mm or less.

[0030] The interlayer film 103 of the laminated glass 10 is, for example, a known thermoplastic resin film made of polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA). The interlayer film 103 of the laminated glass 10 may be transparent or colored. The interlayer film 103 may be composed of two or more layers of film.

[0031] In addition, when the laminated glass 10 is attached to a vehicle, the thickness of the exterior glass sheet 102 located on the exterior side of the vehicle and the thickness of the interior glass sheet 101 located on the interior side of the vehicle may be the same or different. The thickness of the exterior glass sheet 102 is preferably 1.0 mm or more and 3.0 mm or less. If the thickness of the exterior glass sheet 102 is 1.0 mm or more, the strength of the performance such as stone chip resistance is sufficient, and if it is 3.0 mm or less, the mass of the laminated glass 10 is not too large, which is preferable in terms of fuel efficiency of the vehicle. The thickness of the interior glass sheet 101 is preferably 0.3 mm or more and 2.3 mm or less. If the thickness of the interior glass sheet 101 is 0.3 mm or more, the handling property is good, and if it is 2.3 mm or less, the mass is not too large. If the thickness of the exterior glass sheet 102 and the thickness of the interior glass sheet 101 are each 1.8 mm or less, the laminated glass 10 can be made both lightweight and soundproof, which is preferable. When the thickness of the interior side glass sheet 101 is 1.0 mm or less, the interior side glass sheet 101 may be chemically strengthened glass. When the interior side glass sheet 101 is 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.

[0032] Furthermore, when the glass plates 101 and 102 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).

[0033] The shielding layer 104 is formed, for example, by applying a ceramic color paste containing a fusible glass frit containing a black pigment, followed by firing. This can prevent the adhesive applied to the laminated glass 10 from being deteriorated by ultraviolet rays. From the viewpoint of improving weather resistance and functionality such as hydrophilicity and water repellency, various appropriate films may be formed on the main surface of the laminated glass 10.

[0034] 2, both the interior glass sheet 101 and the exterior glass sheet 102 of the laminated glass 10 may have a cutout at a portion where the component unit 11 is to be disposed on the periphery of the laminated glass 10. In the example shown in FIG. 2, the laminated glass 10 and the component unit 11 are joined with an adhesive 21. The component unit 11 may include a camera 30 as an optical device and a mirror base 116 for mounting a mirror 40 as a vehicle part other than an optical device, which are attached to a part of the periphery of the laminated glass 10.

[0035] The adhesive 21 is preferably an adhesive having light resistance and other weather resistance. By using an adhesive having light resistance and other weather resistance as the adhesive 21, it is possible to prevent deterioration of the adhesive 21 due to ultraviolet rays irradiated from outside the vehicle. Specifically, the adhesive 21 is not particularly limited, but modified silicone, modified silicone, etc. may be used.

[0036] As shown in FIG. 2, the parts unit 11 may include tempered glass 111 as a plate-like member, a reinforcing plate 112, a shielding layer 113, a camera bracket 114, a camera cover 115, and a mirror base .

[0037] In the example shown in FIG. 2, the tempered glass 111 has a shape that can be fitted into the cut-out portion of the laminated glass 10. The tempered glass 111 may be any tempered glass that can transmit infrared rays, and the manufacturing method and material thereof are the same as those of the glass plates 101 and 102, and therefore the description thereof will be omitted. The tempered glass that can transmit infrared rays means tempered glass having a transmittance of 50% or more for light having a wavelength of 0.5 μm or more and 1000 μm or less. By using tempered glass that can transmit infrared rays as the tempered glass 111, it is possible to suppress attenuation of the intensity of near infrared rays or far infrared rays used in the camera 30 by the vehicle window glass 1. In addition, as described above, the two glass plates 101 and 102 of the laminated glass 10 may be glass that absorbs ultraviolet rays or infrared rays, and therefore the inside of the vehicle can be prevented from becoming too hot. In addition, the tempered glass 111 has a shape in which the vehicle-interior surface of the laminated glass 10 and the vehicle-interior surface of the component unit 11 are flush with each other at least in the boundary (boundary X shown in FIG. 1) between the laminated glass 10 and the component unit 11, where the urethane sealant 50 for attaching the vehicle window glass 1 to the body panel 60 is applied. In this specification, the two surfaces "float on the same plane" means that the deviation between the two surfaces is 3.0 mm or less. In this specification, the two surfaces "have a shape that fits on the same plane" means that the two surfaces have a thickness that fits on the same plane when the two surfaces are not curved, and that the two surfaces have a thickness and a radius of curvature that fit on the same plane when the two surfaces are curved. Since there is no step between the vehicle-interior surface of the laminated glass 10 and the vehicle-interior surface of the component unit 11, the workability is prevented from being deteriorated when applying the urethane sealant 50 around the periphery of the vehicle window glass 1. As a result, it is possible to provide a vehicle window glass 1 that suppresses attenuation of the intensity of light used in optical devices such as the camera 30 mounted on a vehicle and that is easy to handle despite including the component unit 11.

[0038] In addition, the tempered glass 111 is a peripheral portion of the vehicle window glass 1, and in a region that contributes to mounting the vehicle window glass 1 to the body panel 60, the vehicle inside surface and the vehicle outside surface of the vehicle window glass 1 are stepped. No Here, the region that contributes to the attachment of the vehicle window glass 1 to the body panel 60 is a region on the vehicle window glass 1 where at least the mold 12 and the urethane sealant 50 are provided. No " means that the unevenness of a certain surface is 3.0 mm or less. No "Having a shape" means that if the member is not curved, the surface has no steps. No It means that the member has a thickness, and if the member is curved, the surface has a step. NoIt means that the tempered glass 111 has a thickness and a radius of curvature. In other words, the combined thickness of the tempered glass 111 and the shielding layer 113 formed on the vehicle-interior surface of the tempered glass 111 may be the same as that of the laminated glass 10 in a region that contributes to mounting the vehicle window glass 1 to the body panel 60. In addition, the vehicle-exterior surface of the tempered glass 111 may have the same radius of curvature as the vehicle-exterior surface of the laminated glass 10, and the vehicle-interior surface of the shielding layer 113 may have the same radius of curvature as the vehicle-interior surface of the laminated glass 10. This allows the vehicle window glass 1 to be mounted to the body panel 60 in the same manner as a vehicle window glass not provided with a component unit 11.

[0039] 2, the part unit 11 may attach the camera 30 to the vehicle interior side of the vehicle window glass 1 so that the optical path (the visual field range of the camera 30) of the camera 30 is located in the wiper wiping area of ​​the vehicle window glass 1. Specifically, in the part unit 11, a camera bracket 114 is attached by an adhesive 22 to the vehicle interior surface of a portion of the tempered glass 111 that corresponds to the wiper wiping area of ​​the vehicle window glass 1, and the camera 30 is attached to the camera bracket 114. Note that an adhesive similar to the adhesive 21 may be used as the adhesive 22. By wiping the vehicle exterior surface of the portion of the tempered glass 111 that corresponds to the optical path of the camera 30 by the wiper, it is possible to prevent dirt on the vehicle exterior surface of the tempered glass 111 from affecting the image captured by the camera 30.

[0040] The tempered glass 111 may have a shape in which the vehicle exterior surface of the laminated glass 10 and the vehicle exterior surface of the tempered glass 111 are flush with each other at the boundary X between the laminated glass 10 and the tempered glass 111. Specifically, as shown in FIG. 2, the tempered glass 111 and the laminated glass 10 are joined by an adhesive 21, so it is preferable that the vehicle exterior surface of the laminated glass 10, the vehicle exterior surface of the adhesive 21, and the vehicle exterior surface of the tempered glass 111 are flush with each other. This prevents the boundary X between the laminated glass 10 and the tempered glass 111 from affecting the wiping of the wiper when the vehicle window glass 1 is wiped by the wiper, and prevents dirt such as dust from accumulating at the boundary X. In addition, since the vehicle exterior surface of the laminated glass 10, the vehicle exterior surface of the adhesive 21, and the vehicle exterior surface of the tempered glass 111 are flush with each other, the wiper is unlikely to be damaged even if the wiper wipes the vehicle window glass 1 so as to pass through the boundary X.

[0041] As shown in FIG. 2, the reinforcing plate 112 may back the vehicle interior surface of the reinforced glass 111 and the vehicle interior surface of the laminated glass 10 at the boundary X between the reinforced glass 111 and the laminated glass 10. In the example shown in FIG. 2, the reinforced glass 111, the laminated glass 10, and the reinforcing plate 112 are bonded together by an adhesive 21. Specifically, the reinforcing plate 112 is a plate-like member having a linear protrusion protruding from approximately the center of a flat plate. The reinforcing plate 112 backs the vehicle interior surface of the reinforced glass 111 and the vehicle interior surface of the laminated glass 10 so that the protrusion is partially inserted between the laminated glass 10 and the reinforced glass 111 to which it is bonded. This prevents the bond between the reinforced glass 111 and the laminated glass 10 from being damaged even if a heavy camera 30 or a mirror 40 is attached to the reinforced glass 111.

[0042] The reinforcing plate 112 may be formed, for example, by injection molding a resin material containing glass fiber (for example, a resin material in which 40% of glass fiber (GF) is mixed into polybutylene terephthalate (PBT)).

[0043] As shown in FIG. 2, a shielding layer 113 may be further formed on the vehicle interior surface of the reinforced glass 111, excluding at least a portion corresponding to the optical path of the camera 30. That is, the shielding layer 113 formed on the vehicle interior surface of the reinforced glass 111 may be formed so as to surround the field of view of the camera 30. In the example shown in FIG. 2, a camera bracket 114 is bonded to the vehicle interior surface of the shielding layer 113 formed on the vehicle interior surface of the reinforced glass 111 by an adhesive 22. A camera cover 115 covers the vehicle interior side of the camera 30. The camera cover 115 may be formed so as to be detachable from the camera bracket 114. A mirror base 116 is bonded to the vehicle interior surface of the shielding layer 113, closer to the upper end side of the vehicle window glass 1 than the camera bracket 114. A stay of the mirror 40 is bonded to the vehicle interior surface of the mirror base 116. In this way, the shielding layer 113 prevents the attachment portion of the camera bracket 114 to the tempered glass 111 and the mirror base 116 from being visible from outside the vehicle, thereby improving the design of the vehicle window glass 1 and the vehicle to which the vehicle window glass 1 is attached. Note that the method of forming the shielding layer 113 is similar to that of the shielding layer 104, and therefore a description thereof will be omitted.

[0044] Next, a method for manufacturing the vehicle window glass 1 according to the first embodiment will be described. First, flat interior glass sheet 101 and exterior glass sheet 102 before bending are prepared, and regions in which component units 11 are to be disposed are cut out in each of interior glass sheet 101 and exterior glass sheet 102 (cutting step: S11). The interior glass sheet 101 and exterior glass sheet 102 can be cut out by a known method such as a cutter or laser.

[0045] Next, a ceramic color paste containing a fusible glass frit containing a black pigment is applied to the peripheral portion of the cut interior glass sheet 101 and / or exterior glass sheet 102, and dried. Thereafter, the interior glass sheet 101 and the exterior glass sheet 102 are heated to a temperature equal to or higher than the softening point of the glass sheets, and bent (glass bending process: S12). At this time, the ceramic color paste is fired at the same time, and the shielding layer 104 is formed. The bent interior glass sheet 101 and exterior glass sheet 102 are slowly cooled. The interior glass sheet 101 and exterior glass sheet 102 may be bent simultaneously by overlapping two sheets, or the interior glass sheet 101 and exterior glass sheet 102 may be bent separately.

[0046] Next, as shown in FIG. 2, the interior glass plate 101, the intermediate film 103, and the exterior glass plate 102 are laminated so that the intermediate film 103 is interposed between the interior glass plate 101 and the exterior glass plate 102. The laminated interior glass plate 101, the intermediate film 103, and the exterior glass plate 102 are degassed by heating under reduced pressure using a known nip roller, a rubber bag, a rubber chamber, or the like, and are pre-pressed. After the pre-pressing, the laminate consisting of the interior glass plate 101, the intermediate film 103, and the exterior glass plate 102 is heated and pressurized in an autoclave to be fully pressed, thereby forming a laminated glass (laminated glass forming step: S13). Here, the shape, thickness, and size of the laminated glass 10 are similar to those of a laminated glass for a vehicle window glass not provided with a component unit 11.

[0047] Next, an untempered glass sheet capable of being fitted into the cut-out portion of the laminated glass 10 is prepared. A ceramic color paste containing a fusible glass frit containing a black pigment is applied to the untempered glass, dried, and then heated to a temperature equal to or higher than the softening point of the glass sheet, and bent. At the same time, the ceramic color paste is fired to form a shielding layer 113. When the tempered glass sheet 111 is physically tempered glass, the glass sheet is heated to a temperature equal to or higher than the softening point, bent, and then quenched to be air-cooled and tempered, thereby obtaining the tempered glass sheet 111. When the tempered glass sheet 111 is chemically tempered glass, the glass sheet is heated to a temperature equal to or higher than the softening point, bent, and then annealed. The glass sheet is then annealed and then chemically tempered, thereby obtaining the tempered glass sheet 111 (annealed glass forming step: S14).

[0048] Next, the tempered glass 111 and the laminated glass 10 are joined together using adhesive 21 while the vehicle interior surface of the tempered glass 111 and the vehicle interior surface of the laminated glass 10 are backed by the reinforcing plate 112 (joining step: S15). At this time, the tempered glass 111 and the laminated glass 10 are bonded together while the flat reinforcing plate 112 is backed by the vehicle interior surface of the tempered glass 111 and the vehicle interior surface of the laminated glass 10, making it easy to align the tempered glass 111 and the laminated glass 10 to be joined together.

[0049] Next, a camera bracket 114 is adhered to the vehicle interior surface of the shielding layer 113 using adhesive 22 (camera bracket adhering step: S16). Note that a known double-sided tape may be used to adhere the camera bracket 114, or the adhesive 22 and the double-sided tape may be used in combination. Also, a mirror base 116 is adhered to the vehicle interior surface of the shielding layer 113 (mirror base adhering step: S17). In this manner, it is possible to manufacture the vehicle window glass 1 according to the embodiment 1. Note that the order of the above steps is not limited to the above order and can be changed as appropriate.

[0050] Embodiment 2 FIG. 3 is a cross-sectional view for explaining a vehicle window glass 1A according to embodiment 2. FIG. 3 corresponds to a cross-sectional view of the vehicle window glass 1 cut along the cutting line II-II in FIG. 1, and is a cross-sectional view seen from the left side of the vehicle. The vehicle window glass 1A according to embodiment 2 differs from the vehicle window glass 1 according to embodiment 1 in that it includes a part unit 13 instead of the part unit 11. The part unit 13 according to embodiment 2 differs from the part unit 11 according to embodiment 1 in that it includes a plate-shaped member 131 instead of the tempered glass 111, the reinforcing plate 112, the shielding layer 113, the camera bracket 114, and the mirror base 116. Therefore, in the following description, the same components according to embodiment 2 as those in embodiment 1 are denoted by the same reference numerals, and the description thereof will be omitted.

[0051] The plate-shaped member 131 may include a transmission portion 132 formed from a resin capable of transmitting infrared rays, and a shielding portion 133 formed from a colored resin. The transmission portion 132 may occupy at least a portion of the plate-shaped member 131 that corresponds to the optical path of the camera 30. The plate-shaped member 131 may have a shape corresponding to the tempered glass 111, the reinforcing plate 112, the shielding layer 113, the camera bracket 114, and the mirror base 116 of the first embodiment. The plate-shaped member 131 may be formed by integrally molding the transmission portion 132 and the shielding portion 133 using a molding die having a shape corresponding to the plate-shaped member 131 (two-color molding). The resin forming the transmission portion 132 is not particularly limited, but polycarbonate or the like may be used. The resin forming the shielding portion 133 is not particularly limited, but polycarbonate, ABS resin, or the like may be used. By using the plate-like member 131 having the transmission portion 132 instead of the strengthened glass 111, it is possible to further prevent the intensity of the near-infrared rays and far-infrared rays used by the camera 30 from being attenuated by the vehicle window glass 1A.

[0052] The plate-like member 131 has a shape that allows the vehicle-interior surface of the laminated glass 10 and the vehicle-interior surface of the plate-like member 131 to be flush with each other, at least in the region of the boundary X between the laminated glass 10 and the plate-like member 131 where the urethane sealant 50 for attaching the vehicle window glass 1A to the body panel 60 is applied. The absence of a step between the vehicle-interior surface of the laminated glass 10 and the vehicle-interior surface of the plate-like member 131 prevents deterioration of workability when applying the urethane sealant 50 all the way around the peripheral edge of the vehicle window glass 1A.

[0053] In addition, the plate-shaped member 131 is provided at the peripheral portion of the vehicle window glass 1A, and in a region that contributes to mounting the vehicle window glass 1A to the body panel 60, the vehicle inner surface and the vehicle outer surface of the vehicle window glass 1A are provided with a step. No In other words, the plate-like member 131 may have the same thickness and radius of curvature as the laminated glass 10 in an area that contributes to mounting the vehicle window glass 1A to the body panel 60. This allows the vehicle window glass 1A to be mounted to the body panel 60 in the same manner as a vehicle window glass not including the component unit 13.

[0054] 3, the part unit 13 may be attached to the vehicle interior side of the vehicle window glass 1 so that the optical path of the camera 30 (the field of view of the camera 30) is positioned in the wiper wiping area of ​​the vehicle window glass 1A. By wiping the vehicle exterior surface of the transmissive portion 132 of the plate-shaped member 131 with the wiper, it is possible to prevent dirt on the vehicle exterior surface of the plate-shaped member 131 from affecting the image captured by the camera 30.

[0055] In addition, the plate-like member 131 may have a shape in which the vehicle-exterior surface of the laminated glass 10 and the vehicle-exterior surface of the plate-like member 131 are flush with each other at the boundary X between the laminated glass 10 and the plate-like member 131. Specifically, as shown in FIG. 3, since the plate-like member 131 and the laminated glass 10 are joined by the adhesive 21, it is preferable that the vehicle-exterior surface of the laminated glass 10, the vehicle-exterior surface of the adhesive 21, and the vehicle-exterior surface of the plate-like member 131 are flush with each other. This prevents the boundary X between the laminated glass 10 and the plate-like member 131 from affecting the wiping of the wiper when the vehicle window glass 1A is wiped by the wiper, and prevents dirt such as dust from accumulating at the boundary X. In addition, since the vehicle-exterior surface of the laminated glass 10, the vehicle-exterior surface of the adhesive 21, and the vehicle-exterior surface of the plate-like member 131 are flush with each other, the wiper is unlikely to be damaged even if the wiper wipes the vehicle window glass 1 so as to pass through the boundary X.

[0056] 3, the shielding portion 133 of the plate-like member 131 may include an extension portion 133A extending in a plate shape from a boundary X between the plate-like member 131 and the laminated glass 10 onto the vehicle interior surface of the laminated glass 10. The extension portion 133A lines the vehicle interior surface of the laminated glass 10. This increases the area on which the adhesive 21 that bonds the plate-like member 131 and the laminated glass 10 is applied, so that even if a heavy camera 30 or a mirror 40 is attached to the plate-like member 131, the bond between the plate-like member 131 and the laminated glass 10 is prevented from being damaged.

[0057] 3, the shielding portion 133 may occupy at least a portion of the plate-shaped member 131 excluding a portion corresponding to the optical path of the camera 30. That is, the shielding portion 133 of the plate-shaped member 131 may be formed so as to surround the transmission portion 132, which is the field of view of the camera 30. In the example shown in FIG. 3, the shielding portion 133 has a shape corresponding to the camera bracket 114, and the camera cover 115 may be formed so as to be detachable from the portion of the shielding portion 133 corresponding to the camera bracket 114. The shielding portion 133 has a shape corresponding to the mirror base 116, and the stay of the mirror 40 is bonded to the portion of the shielding portion 133 corresponding to the mirror base 116. In this way, the shielding portion 133 prevents the bonding portion of the camera 30 and the stay of the mirror 40 to the plate-shaped member 131 from being visible from outside the vehicle, thereby improving the design of the vehicle window glass 1A and the vehicle to which the vehicle window glass 1A is attached.

[0058] Next, a description will be given of a manufacturing method of the vehicle window glass 1A according to the present embodiment 2. In the manufacturing method of the vehicle window glass 1A, the notching step S21, the glass bending forming step S22, and the laminated glass forming step S23 are similar to the above-mentioned S11, S12, and S13, and therefore the description thereof will be omitted.

[0059] Next, a plate-like member 131 capable of being fitted into the cut-out portion of the laminated glass 10 is prepared (plate-like member forming step: S24). The method for producing the plate-like member 131 has been described above, and therefore will not be described here.

[0060] Next, the plate-like member 131 and the laminated glass 10 are joined using the adhesive 21 while the vehicle interior surface of the laminated glass 10 is backed by the extending portion 133A of the shielding portion 133 (joining step: S25). At this time, since the plate-like member 131 and the laminated glass 10 are bonded while the vehicle interior surface of the laminated glass 10 is backed by the extending portion 133A extending in a flat plate shape, it is easy to align the plate-like member 131 and the laminated glass 10 to be joined. In this manner, it is possible to manufacture the vehicle window glass 1A according to embodiment 2. Note that the order of the above steps is not limited to the above order and can be changed as appropriate.

[0061] Variations Next, a modified example of the vehicle window glass 1A according to the second embodiment will be described. In the vehicle window glass 1A according to the modified example, the shielding portion 133 of the component unit 13 may be formed using a metal. By using the metal shielding portion 133 instead of the resin shielding portion 133, the strength of the component unit 13 is increased, and a heavier vehicle component such as an optical device can be attached to the vehicle window glass 1A. The metal for forming the shielding portion 133 is not particularly limited, and a rolled steel plate to which an electrodeposition coating is applied may be used. In addition, the transmission portion 132 may have a shape in which the vehicle exterior surface of the transmission portion 132 and the vehicle exterior surface of the shielding portion 133 are in the same plane (flush) at the boundary between the transmission portion 132 and the shielding portion 133. This prevents the boundary between the transmission portion 132 and the shielding portion 133 from affecting the wiper wiping and prevents dirt such as dust from accumulating at the boundary when the wiper wipes the vehicle window glass 1A. In addition, at the boundary between the transmitting portion 132 and the shielding portion 133, the vehicle exterior surface of the transmitting portion 132 and the vehicle exterior surface of the shielding portion 133 are in the same plane, so that the wiper is unlikely to be damaged even if it wipes the vehicle window glass 1 so as to pass through the boundary.

[0062] Third embodiment FIG. 4 is a perspective view for explaining a vehicle window glass 1B according to embodiment 3. FIG. 5 corresponds to a cross-sectional view of the vehicle window glass 1B cut along the cutting line VV in FIG. 4, and is a cross-sectional view seen from the left side of the vehicle. The embodiment 3 differs from the embodiment 1 in that only the vehicle-interior glass sheet 101 of the laminated glass 10 is cut out. The vehicle window glass 1B according to embodiment 3 also differs from the vehicle window glass 1 according to embodiment 1 in that it includes a part unit 14 instead of the part unit 11. The part unit 14 according to embodiment 3 also differs from the part unit 11 according to embodiment 1 in that it includes a plate-shaped member 141 instead of the tempered glass 111, the reinforcing plate 112, the shielding layer 113, the camera bracket 114, and the mirror base 116. Therefore, in the following description, the same reference numerals are given to the same configurations according to embodiment 3 as those of embodiment 1, and the description thereof will be omitted.

[0063] The interior glass sheet 101 of the laminated glass 10 may be cut out at a portion where the component unit 14 is disposed on the peripheral edge of the laminated glass 10. Since the exterior glass sheet 102 of the laminated glass 10 is not cut out, it is possible to prevent a step from being formed on the exterior surface of the vehicle window glass 1B. This makes it possible to prevent the wiper's wiping of the vehicle window glass 1B from being affected.

[0064] The plate-like member 141 may have a shape corresponding to the strengthened glass 111, the reinforcing plate 112, the shielding layer 113, the camera bracket 114, and the mirror base 116. The plate-like member 141 also has an opening 141A in which a portion corresponding to the optical path of the camera 30 is opened. That is, in the optical path of the camera 30, there is only the exterior glass plate 102 of the laminated glass 10, in addition to air. This makes it possible to prevent the intensity of the near-infrared rays and far-infrared rays used by the camera 30 from being attenuated by the vehicle window glass 1B.

[0065] The plate-like member 141 has an area covering the cut-out portion of the interior-side glass plate 101 of the laminated glass 10. The plate-like member 141 is adhered to the interior-side surface of the exterior-side glass plate 102 of the laminated glass 10 with an adhesive 23. Specifically, in the example shown in FIG. 5 , the exterior-side surface of the plate-like member 141 excluding the opening 141A is adhered to the interior-side surface of the exterior-side glass plate 102 with the adhesive 23. This makes it possible to increase the adhesion area between the exterior-side glass plate 102 and the plate-like member 141, and to strengthen the adhesion between the laminated glass 10 and the component unit 14. Note that an adhesive similar to the adhesive 21 may be used as the adhesive 23.

[0066] The plate-shaped member 141 may be made of a colored resin or a metal. The colored resin or metal forming the plate-shaped member 141 may be made of the materials described in the second embodiment.

[0067] The plate-shaped member 141 is a window glass for a vehicle, and at least a boundary between the laminated glass 10 and the plate-shaped member 141 (boundary X' shown in FIG. 4) 1B In an area where a urethane sealant 50 for attaching the vehicle window glass 1B to a body panel 60 is applied, the vehicle interior surface of the laminated glass 10 and the vehicle interior surface of the plate-shaped member 141 are flush with each other. Since there is no step between the vehicle interior surface of the laminated glass 10 and the vehicle interior surface of the plate-shaped member 141, deterioration of workability when applying the urethane sealant 50 all the way around the peripheral portion of the vehicle window glass 1B is prevented.

[0068] In addition, the plate-shaped member 141 is provided at the peripheral portion of the vehicle window glass 1B, and in a region that contributes to the attachment of the vehicle window glass 1B to the body panel 60, the vehicle inner surface and the vehicle outer surface of the vehicle window glass 1B are provided with a step. NoIn other words, the combined thickness of the plate-shaped member 141, the vehicle exterior glass plate 102, and the adhesive 23 may be the same as that of the laminated glass 10 in an area that contributes to the attachment of the vehicle window glass 1B to the body panel 60. The vehicle interior surface of the plate-shaped member 141 may have the same radius of curvature as that of the vehicle interior surface of the laminated glass 10 in an area that contributes to the attachment of the vehicle window glass 1B to the body panel 60. This allows the vehicle window glass 1B to be attached to the body panel 60 in the same manner as a vehicle window glass not including the component unit 13.

[0069] 5, the part unit 14 may be provided with the camera 30 attached to a wiper wiping area of ​​the vehicle window glass 1B. The exterior surface of the exterior glass sheet 102 at a portion corresponding to the optical path of the camera 30 is wiped by the wiper, thereby preventing dirt on the exterior surface of the exterior glass sheet 102 from affecting the image captured by the camera 30.

[0070] 5, the plate-like member 141 may include an extension 141B extending in a plate shape from a boundary X' between the plate-like member 141 and the laminated glass 10 onto the vehicle interior surface of the laminated glass 10. The extension 141B lines the vehicle interior surface of the laminated glass 10. This increases the area on which the adhesive 23 that bonds the plate-like member 141 and the laminated glass 10 is applied, so that even if a heavy camera 30 or a mirror 40 is attached to the plate-like member 141, the bond between the plate-like member 141 and the laminated glass 10 is prevented from being damaged.

[0071] 5, the plate-shaped member 141 may have a shape corresponding to the camera bracket 114, and the camera cover 115 may be formed so as to be detachable from a portion of the plate-shaped member 141 corresponding to the camera bracket 114. The plate-shaped member 141 may have a shape corresponding to the mirror base 116, and the stay of the mirror 40 is bonded to a portion of the plate-shaped member 141 corresponding to the mirror base 116. Since the plate-shaped member 141 is made of a colored resin or metal, the plate-shaped member 141 prevents the bonding portion of the stays of the camera 30 and the mirror 40 to the plate-shaped member 141 from being visible from outside the vehicle. This can improve the design of the vehicle window glass 1B and the vehicle to which the vehicle window glass 1B is attached.

[0072] Next, a description will be given of a manufacturing method of the vehicle window glass 1B according to the present embodiment 3. In the manufacturing method of the vehicle window glass 1B, the glass bending forming step S32 and the laminated glass forming step S33 are similar to the above-mentioned S12 and S13, and therefore the description thereof will be omitted.

[0073] First, flat interior glass sheet 101 and exterior glass sheet 102 before bending are prepared, and a region in which component unit 14 is to be disposed is cut out in interior glass sheet 101 (notching step: S31). As in S11, the method for cutting out interior glass sheet 101 can be a known method such as with a cutter or laser. After notching step S31, a glass bending step S32 and a laminated glass forming step S33 are performed.

[0074] Next, a plate-shaped member 141 capable of being fitted into the cut-out portion of the laminated glass 10 is prepared (plate-shaped member forming step: S34). The plate-shaped member 141 may be formed by filling a molding die having a shape corresponding to the plate-shaped member 141 with molten resin material or metal material and solidifying the resin material or metal material.

[0075] Next, the plate-like member 141 and the laminated glass 10 are joined using adhesive 23 while the vehicle interior surface of the laminated glass 10 is backed by the extending portion 141B of the plate-like member 141 (joining step: S35). At this time, since the plate-like member 141 and the laminated glass 10 are bonded while the vehicle interior surface of the laminated glass 10 is backed by the extending portion 141B extending in a flat plate shape, it is easy to align the plate-like member 141 and the laminated glass 10 to be joined. In this manner, it is possible to manufacture the vehicle window glass 1B according to embodiment 3. Note that the order of the above steps is not limited to the above order and can be changed as appropriate.

[0076] While the present invention has been described above in accordance with the above-described embodiment, the present invention is not limited to the configuration of the above-described embodiment, and naturally includes various modifications, alterations, and combinations that may be made by a person skilled in the art within the scope of the invention as defined in the claims of the present application.
