[0028] <Embodiment>
[0029] Figure 1A is a drawing illustrating an example of the vehicle window glass 100 in an exploded state. Figure 1B is a drawing illustrating an example of the vehicle window glass 100 in an exploded state of a part of the constituent elements. Figure 2A is a drawing illustrating an example of the cross-sectional structure of the vehicle window glass 100. Figure 2B is a drawing illustrating an example of the structure of the glass sheet 110 of the vehicle window glass 100. Figure 2A is a drawing illustrating an example of the cross-sectional structure of the vehicle window glass 100 and the antenna device 50 in a state of being installed in the vehicle body 10. Figure 2A is a drawing illustrating the vehicle body 10 of the vehicle 1.
[0030] The vehicle 1 includes a vehicle body 10, an antenna device 50, and a vehicle window glass 100. The vehicle body 10 has a window frame 11, a panel 12, a bolt 15, and an adhesive 20. The antenna-equipped vehicle window glass 100A of the embodiment includes the antenna device 50 and the vehicle window glass 100.
[0031] The vehicle window glass 100 includes a glass sheet 110, a spacer 120, and a metal sheet 130. The antenna device 50 is attached to a main surface 110A on the cabin outside (+Z direction side) of the glass sheet 110 of the vehicle window glass 100. As an example, the antenna device 50 is a shark fin type antenna device.
[0032] Figure 1A In the middle, the antenna device 50, the glass sheet 110, the spacer 120, and the metal sheet 130 are shown from an oblique upper side. Figure 1A The main surface 110A on the cabin outside of the glass sheet 110 is shown. The main surface 110A on the cabin outside is an upper surface of the glass sheet 110.
[0033] Figure 1B In the middle, the antenna device 50 and the glass sheet 110 are shown from an oblique lower side. Figure 1B The main surface 110B on the cabin inside (-Z direction side) of the glass sheet 110 is shown, and the spacer 120 and the metal sheet 130 are omitted. The main surface 110B on the cabin inside is a lower surface of the glass sheet 110.
[0034] <Antenna device 50>
[0035] The antenna device 50 has an antenna main body 51, a fixing shaft 52, and a nut 53.
[0036] The antenna main body 51 is a frame body in which an antenna element or the like is built in. A lower surface of the antenna main body 51 is an attachment surface 51A attached to the main surface 110A on the cabin outside of the glass sheet 110. An antenna element built in the antenna main body 51 is connected to a signal line passing through the inside of the fixing shaft 52.
[0037] The fixing shaft 52 accommodates a coaxial cable not shown therein. A core wire of the coaxial cable is connected to the signal line passing through the inside of the fixing shaft 52, the fixing shaft 52 is connected to a shield wire of the coaxial cable, and the coaxial cable is drawn out from the fixing shaft 52. Here, the coaxial cable can be drawn out from the front end of the fixing shaft 52 or from the middle of the fixing shaft 52. In addition, the fixing shaft 52 is connected to the metal sheet 130. Since the metal sheet 130 can shield noise coming from the cabin inside, the antenna characteristics of the antenna device 50 can be improved. In addition, in the case where there is no need to shield noise, the fixing shaft 52 can not be connected to the metal sheet 130.
[0038] The fixing shaft 52 is a bolt-like member formed with a helical thread on the outer side surface, and has a base 52A at the upper end connected to the mounting surface 51A of the antenna body 51. The base 52A is a rectangular parallelepiped, and is provided to prevent the antenna body 51 from rotating. In addition, the base 52A can also include a claw or the like structure for temporarily fixing the spacer 120.
[0039] The fixing shaft 52 is inserted into the through hole 120A of the spacer 120 and the through hole 130A of the metal plate 130 from the upper side when the antenna body 51 is fastened to the glass plate 110, and the nut 53 is assembled at the lower end of the fixing shaft 52. In addition, the fixing shaft 52 is described here as a bolt-like member protruding from the lower surface of the antenna body 51 and fastened by the nut 53, but the fixing shaft 52 is not limited to such a structure. The fixing shaft 52 can also be an anchor bolt fixed to the lower surface of the antenna body 51, for example. The anchor bolt is advantageous in terms of preventing rotation and lateral movement.
[0040] In addition, the antenna element built into the antenna body 51 is an antenna element that transmits or receives electric waves of a prescribed frequency band. The antenna element can be an antenna element that can receive electric waves of frequencies in the VHF (Very High Frequency) band to the UHF (Ultra High Frequency) band. Specifically, the antenna element can be an antenna element that can receive electric waves of frequencies of 30 MHz to 3 GHz. In addition, the antenna element can also be an antenna element that can receive at least one of electric waves of Band III (174 MHz to 240 MHz) of DAB (Digital Audio Broadband) and electric waves of terrestrial digital television broadcast waves (470 MHz to 710 MHz) included in the VHF band to the UHF band. In addition, the antenna element can also be an antenna element that can receive electric waves of the FM broadcast wave band (76 MHz to 108 MHz) and narrowband ITS (Intelligent Transport Systems) including 760 MHz.
[0041] Furthermore, the vehicle window glass of the embodiment may also be an antenna element capable of transmitting and receiving radio waves in the LTE (Long Term Evolution) band, an antenna element capable of receiving radio waves in the satellite communication bands such as GNSS (Global Navigation Satellite System) and SDARS (Satellite Digital Audio Radio Service), or an antenna element capable of transmitting and receiving radio waves in the 5G (5th Generation Mobile Communication System) band. As an antenna element for 5G, examples include antenna elements capable of transmitting and receiving radio waves in the short-range communication band (e.g., the 5.8 GHz band) of DSRC (Dedicated Short Range Communication), used for V2X (Vehicle to Everything) communication such as vehicle-to-everything (V2X) communication. In addition, the antenna element is not limited to one of the antenna elements exemplified above; multiple antenna elements may be integrated and arranged in one place, or multiple antenna elements may be distributed and arranged near the glass plate 110.
[0068] <Glass Plate 110>
[0042] The glass panel 110 has a main surface 110A on the outer side of the carriage, a main surface 110B on the inner side of the carriage, a through hole 110C, and a ceramic layer 115. The through hole 110C is an example of a first through hole. The ceramic layer 115 is an example of a shielding layer.
[0043] like Figure 2A As shown, the glass panel 110 is mounted on the window frame 11 of the vehicle body 10 as an example. The window frame 11 is formed into a flange shape along the outer edge of the vehicle window glass 100. The vehicle window glass 100 is mounted on the window frame 11 by bonding the peripheral portion of the main surface 110B on the inner side of the vehicle compartment of the glass panel 110 to the window frame 11 using an adhesive 20 such as polyurethane resin. The peripheral portion of the main surface 110B on the inner side of the vehicle compartment is a circumferential portion of the main surface 110B on the inner side of the vehicle compartment that is slightly inward than the outer edge of the vehicle window glass 100 and runs along the outer edge.
[0044] The through hole 110C is located at the position of the fixing shaft 52 of the part where the antenna body 51 is installed on the glass plate 110, and passes between the main surface 110A on the outside of the carriage and the main surface 110B on the inside of the carriage.
[0045] The ceramic layer 115 is formed in a region of the main surface 110B on the inside of the vehicle cabin that overlaps the antenna main body 51 in plan view. The ceramic layer 115 is, for example, a sintered body of a dark ceramic paste, and is formed by applying a ceramic color paste containing a fusible glass frit containing a black pigment and sintering. The ceramic layer 115 is formed in order to prevent the adhesive 20 from deteriorating due to ultraviolet rays in a state in which the vehicle window glass 100 is bonded to the vehicle body 10, and to make the connection portion of the vehicle window glass 100 and the vehicle body 10 invisible from the outside of the vehicle, thereby making the appearance good.
[0046] In addition, the ceramic layer 115 is provided to the peripheral edge portion of the glass sheet 110 in plan view. The peripheral edge portion of the glass sheet 110 refers to a peripheral portion of the glass sheet 110 that is slightly inward of the outer edge of the glass sheet 110 in plan view and that is along the outer edge. Further, the ceramic layer 115 provided to the peripheral edge portion of the glass sheet 110 can be independent of the ceramic layer 115 formed in the region that overlaps the antenna main body 51.
[0047] The glass sheet 110 can be an inorganic glass or an organic glass. As the inorganic glass, for example, soda-lime glass, alumino-silicate glass, boron-silicate glass, non-alkali glass, quartz glass, or the like can be used without particular limitation. Among them, soda-lime glass is particularly preferable from the viewpoint of manufacturing cost and formability.
[0048] The glass sheet 110 can be a single-layer glass or a laminated glass. In the case where the glass sheet 110 is a single-layer glass, a strengthened glass is preferable as an example. As the strengthened glass, a physically strengthened glass (for example, air-cooling strengthened glass) can be used.
[0049] In the case where the glass sheet 110 is a laminated glass, a glass sheet provided to the outside of the vehicle cabin, a glass sheet provided to the inside of the vehicle cabin, and an interlayer film provided between the two glass sheets are provided. The two glass sheets are bonded by the interlayer film.
[0051] The glass sheet 110 is a transparent plate-shaped glass sheet. The glass sheet 110 has a main surface on the outside of the vehicle cabin and a main surface on the inside of the vehicle cabin. The forming method of the glass sheet 110 is not particularly limited. For example, in the case of an inorganic glass, a glass sheet formed by a float method or the like is preferable. In addition, here, as an example, a transparent form of the glass sheet 110 is described, but the glass sheet 110 can not be transparent.
[0052] In the case where the glass sheet 110 is an inorganic glass, the glass sheet 110 can be either an un-strengthened glass or a strengthened glass. The un-strengthened glass is a glass formed by shaping a molten glass into a plate shape and subjected to slow cooling. The strengthened glass is a glass in which a compressive stress layer is formed on the surface of the un-strengthened glass, and can be either an air-cooling strengthened glass or a chemically strengthened glass.
[0053] In the case where the strengthened glass is physical strengthened glass (for example, air-cooled strengthened glass), the glass surface can be strengthened by a process other than slow cooling, such as quenching the glass sheet from a temperature near the softening point after uniform heating in the bending forming, and using the temperature difference between the glass surface and the glass interior to generate a compressive stress layer on the glass surface. In the case where the strengthened glass is chemical strengthened glass, the glass surface can be strengthened by ion exchange or the like after the bending forming. In addition, the glass sheet 110 can be glass that absorbs ultraviolet rays or infrared rays. The glass sheet 110 is preferably transparent, but can be a glass sheet that is colored to an extent that does not impair transparency.
[0054] The glass sheet 110 can be a curved shape that protrudes outward of the vehicle cabin when installed to the vehicle body 10. The laminated glass can have a single-curved shape that is bent in only one direction, or can have a multi-curved shape that is bent in two directions (for example, the up-down direction and the left-right direction orthogonal to the up-down direction when the laminated glass is installed to the vehicle body 10). The bending forming of the laminated glass can be performed using gravity forming, press forming, or roll forming. In the case where the laminated glass is bent to a prescribed curvature, the radius of curvature of the laminated glass can be 1000 mm or more and 100000 mm or less.
[0055] In the case where the glass sheet 110 is a single-layer glass, the thickness of the glass sheet is preferably 2.0 mm or more and 5.0 mm or less. If the thickness of the glass sheet is 2.0 mm or more, the strength of the stone chip resistance and the like is sufficient, and if it is 5.0 mm or less, the mass of the glass sheet 110 does not become excessively large, which is preferable from the viewpoint of vehicle fuel consumption. In the case where the glass sheet 110 is a laminated glass, the thickness of the glass sheet on the vehicle cabin exterior side can be the same as the thickness of the glass sheet on the vehicle cabin interior side, or can be different when the laminated glass is installed to the vehicle body 10. The thickness of the glass sheet is preferably 1.0 mm or more and 3.0 mm or less. If the thickness of the glass sheet is 1.0 mm or more, the strength of the stone chip resistance and the like is sufficient, and if it is 3.0 mm or less, the mass of the laminated glass does not become excessively large, which is preferable from the viewpoint of vehicle fuel consumption. The thickness of the glass sheet is preferably 0.3 mm or more and 2.3 mm or less. By making the thickness of the glass sheet 0.3 mm or more, the workability is good, and by making it 2.3 mm or less, the mass does not become excessively large. If the thickness of both glass sheets is 1.8 mm or less, the weight reduction and sound insulation of the laminated glass can be balanced, and thus is preferable. In addition, in the case where the thickness of the glass sheet is 1.0 mm or less, the glass sheet can be chemical strengthened glass. In the case where the glass sheet is chemical strengthened glass, the surface compressive stress of the glass is 300 MPa or more, and the depth of the compressive stress layer is 2 μm or more.
[0056] When the glass plate 110 is plexiglass, examples of materials for plexiglass include transparent resins such as polycarbonate or acrylic resin (e.g., polymethyl methacrylate).
[0057] When glass plate 110 is laminated glass, the interlayer is a transparent or translucent dielectric material sandwiched between the two glass plates. The two glass plates are bonded together by the interlayer. Examples of materials that can be used as the interlayer include thermoplastic polyvinyl butyral (PVB) and ethylene vinyl acetate copolymer (EVA). The interlayer can be transparent or colored. Furthermore, the interlayer can consist of two or more layers.
[0058] Ceramic layers 115 are disposed layer by layer on the periphery of the main surface of the inner side of the glass panel 110. As an example, when the glass panel 110 is laminated glass, the ceramic layers 115 disposed on the two glass panels have the same shape and position when viewed from above. In addition, the ceramic layers 115 may be disposed only on the main surface of the inner side of the glass panel on the outer side of the car, or only on the main surface of the inner side of the glass panel on the inner side of the car.
[0059] Additionally, this example illustrates that glass plate 110 is... Figure 2A The single-layer glass shown is in the form of a single pane of glass, but the glass plate 110 can also be as shown. Figure 2C The laminated glass shown. Figure 2C This is an example of a cross-sectional structure of a vehicle window glass 100 when the glass panel 110 is laminated glass. Details regarding the material of the laminated glass, etc., are as described above; here, we will use... Figure 2C The structure of the glass plate 110, which is a laminated glass, will be described.
[0060] The glass plate 110, as a laminated glass, has glass plates 111 and 112, an interlayer film 113, and a ceramic layer 115. Glass plate 111 is an example of a first glass plate, and glass plate 112 is an example of a second glass plate. Furthermore, although... Figure 2C Although not shown in the diagram, the glass panel 110, which is a laminated glass, may also have a Low-E film formed on the main surface 112B of the glass panel 112 on the inner side of the vehicle compartment. The Low-E film is a conductive film that reflects far-infrared rays, thereby improving the heat insulation or thermal insulation performance of the glass panel 110.
[0061] The glass plate 110, which is a laminated glass, is formed by bonding a glass plate 111 with a ceramic layer 115 and a glass plate 112 disposed on the inner side of the carriage of the vehicle body 10 through an interlayer film 113.
[0062] The glass plate 110 as the laminated glass has a through-hole 110C. The through-hole 110C penetrates the glass plate 111, the glass plate 112, the interlayer film 113, and the ceramic layer 115 in the thickness direction (Z direction). The positions of the through-holes of the glass plate 111, the glass plate 112, the interlayer film 113, and the ceramic layer 115 coincide with each other in plan view, and the through-hole 110C is shown in Figure 2C Fig. 6. The through-hole 110C is provided at a position overlapping the antenna device 50 in plan view, like the through-hole 110C of the glass plate 110 as the single-layer glass shown in Figure 2A Fig. 5. In addition, the size of the through-hole of the glass plate 111 in plan view can be different from that of the through-hole of the glass plate 112.
[0063] The glass plate 111 has a main surface 111A on the outside of the vehicle cabin and a main surface 111B on the inside of the vehicle cabin. The main surface 111A is an example of the first main surface, and the main surface 111B on the inside of the vehicle cabin is an example of the second main surface. The glass plate 112 has a main surface 112A on the outside of the vehicle cabin and a main surface 112B on the inside of the vehicle cabin. The main surface 112A is an example of the third main surface, and the main surface 112B on the inside of the vehicle cabin is an example of the fourth main surface. The main surface 111A is an example of the main surface on the outside of the vehicle cabin, and the main surface 112B is an example of the main surface on the inside of the vehicle cabin.
[0064] In a case where the glass plate 110 as the laminated glass shown in Figure 2C is used instead of the glass plate 110 as the single-layer glass shown in Figure 2A , the vehicle window glass 100 of the embodiment functions in the same way. A configuration using the glass plate 110 as the single-layer glass shown in Figure 2A will be described below as an example.
[0065] <Spacer 120>
[0066] The spacer 120 is a member provided on the inside of the through-hole 110C and the main surface 110B on the inside of the vehicle cabin of the glass plate 110 and holds the fixing shaft 52 of the antenna device 50 having the mounting surface 51A abutting against the main surface 110A on the outside of the vehicle cabin in the inside of the through-hole 110C.
[0067] Here, the provision of the spacer 120 on the inside of the through-hole 110C and the main surface 110B on the inside of the vehicle cabin means that, in a case where the ceramic layer 115 is formed on the main surface 110B on the inside of the vehicle cabin, the spacer 120 is provided on the inside of the through-hole 110C and the ceramic layer 115 formed on the main surface 110B on the inside of the vehicle cabin. The spacer 120 is preferably made of resin, but can be made of a relatively soft metal such as aluminum, for example.
[0068] The spacer 120 has a first portion 121 disposed inside the through hole 110C of the glass plate 110, and a second portion 122 abutting against the ceramic layer 115 formed on the main surface 110B inside the carriage.
[0069] The first part 121, for example, is a cylindrical portion protruding upward from the upper surface of the second part 122. The first part 121, for example, is embedded inside the through-hole 110C. The top-view dimension of the first part 121, for example, is the same as the top-view dimension of the through-hole 110C. This is to prevent the first part 121 from shifting inside the through-hole 110C, thereby suppressing positional shift of the antenna device 50. Furthermore, by embedding the first part 121 inside the through-hole 110C, a seal can be formed between the first part 121 and the through-hole 110C, enabling waterproofing. Additionally, by embedding the first part 121 inside the through-hole 110C, the edges (edges) of the through-hole 110C in the glass plate 110 can be protected, and damage to the edges (edges) can be suppressed.
[0070] like Figure 2B As shown, the first part 121 has a square through-hole 121A when viewed from above. The shape and size of the through-hole 121A when viewed from above are, for example, the shape and size of the base 52A of the antenna device 50, and the depth of the through-hole 121A is, for example, the length in the Z direction of the base 52A. By embedding the base 52A into the through-hole 121A, a seal can be formed between the through-hole 121A and the base 52A, enabling waterproofing. Furthermore, by embedding the square base 52A when viewed from above into the square through-hole 121A, positional displacement of the base 52A can be suppressed, thereby suppressing positional displacement of the antenna device 50. Additionally, if positional displacement of the antenna device 50 is not a problem, the through-hole 121A can also be a shape other than a square, such as a circle, when viewed from above. Furthermore, if the base 52A is circular when viewed from above, the through-hole 121A can also be circular when viewed from above.
[0071] The second part 122 is, for example, a flat plate with a constant thickness in the Z direction. The second part 122 has a through hole 122A communicating with the through hole 121A. Through holes 121A and 122A are examples of a second through hole. Through hole 122A is, for example, circular in plan view and has a plan view dimension consistent with that of the fixed shaft 52.
[0072] In this way, the spacer 120 is provided on the inside of the through-hole 110C of the glass plate 110 and the main surface 110B on the inside of the passenger compartment, and the spacer 120 is not present between the main surface 110A on the outside of the passenger compartment of the glass plate 110 and the antenna device 50. That is, the spacer 120 is provided only on the inside of the through-hole 110C of the glass plate 110 and the main surface 110B on the inside of the passenger compartment. Therefore, the antenna device 50 can be stably fixed to the glass plate 110.
[0073] In addition, in a case where the ceramic layer 115 is not provided, the second portion 122 abuts against the main surface 110B on the inside of the passenger compartment. Further, in a case where a portion where the ceramic layer 115 is not provided is present at a portion of the portion overlapping the antenna main body 51 in plan view, the second portion 122 abuts against the ceramic layer 115 at the portion where the ceramic layer 115 is present and abuts against the main surface 110B on the inside of the passenger compartment at the portion where the ceramic layer 115 is not present.
[0074] In addition, in order to position the spacer 120, a protrusion or a groove can be provided on the inside of the through-hole 110C, the main surface 110B on the inside of the passenger compartment, the ceramic layer 115, or the like.
[0075] <metal plate 130>
[0076] The metal plate 130 is a member that is provided so as to overlap the lower surface of the second portion 122 of the spacer 120. The metal plate 130 is preferably a relatively soft metal such as aluminum, but can be made of a metal other than aluminum.
[0077] The metal plate 130 has a through-hole 130A. The shape and size in plan view of the through-hole 130A coincide with those of the through-hole 122A of the spacer 120 as an example. This is because the fixing shaft 52 passes through the through-hole 130A.
[0078] In addition, the metal plate 130 is connected to the fixing shaft 52 by a nut 53 that is assembled to the lower end of the fixing shaft 52. The fixing shaft 52 is connected to the shield line of the coaxial cable and to the reference potential point of the vehicle body 10. That is, the metal plate 130 is connected to the reference potential point of the vehicle body 10. The reference potential point of the vehicle body 10 is a reference point of the potential of the vehicle body 10, and is connected to the negative terminal of the battery of the vehicle 1 as an example.
[0079] In this way, by connecting the metal plate 130 to the reference potential point of the vehicle body 10, noise from the inside of the passenger compartment can be shielded, and the antenna characteristics of the antenna device 50 can be improved. In addition, in a case where noise does not need to be shielded, the metal plate 130 can not be connected to the fixing shaft 52.
[0080] The metal plate 130 is fastened to the window frame 11 of the vehicle body 10 by the bolt 15. The metal plate 130 is provided so that the fastening force of the nut 53 does not act directly on the spacer 120. Further, by dispersing the fastening force with the metal plate 130, the antenna device 50 can be fixed to the glass plate 110 with a stronger fastening force, and breakage of the glass plate 110 can be suppressed.
[0081] In addition, the vehicle window glass 100 can not include the metal plate 130. For example, in a case where the fastening force applied to the spacer 120 is not a problem, the vehicle window glass 100 can be a structure that does not include the metal plate 130 and the nut 53 abuts against the lower surface of the second portion 122 of the spacer 120.
[0082] Further, the metal plate 130 can also be an extension of the window frame 11 and be a part of the vehicle body 10. In this case, the metal plate 130 can be integrally formed with the window frame 11, and can not be a structure that is fastened by the bolt 15.
[0083] <Mounting the antenna device 50 to the vehicle window glass 100>
[0084] By inserting the spacer 120 into the through-hole 110C of the glass plate 110, overlapping the metal plate 130 below the spacer 120, and inserting the fixing shaft 52 into the through-holes 120A and 130A from the upper side, and assembling the nut 53 to the lower end of the fixing shaft 52, the antenna main body 51 can be fastened to the glass plate 110.
[0085] In addition, a panel 12 is provided on the inside of the vehicle cabin, and thus the window frame 11, the bolt 15, the fixing shaft 52, the nut 53, the ceramic layer 115, the spacer 120, and the metal plate 130 are covered and cannot be seen from the inside of the vehicle cabin. The panel 12 is a cover that is exposed on the roof of the vehicle.
[0086] <Effects>
[0087] The vehicle window glass 100 includes a glass plate 110 mounted on a window frame 11 of a vehicle body 10 and having a through-hole 110C (first through-hole) between a main surface 110A on the outside of a passenger compartment and a main surface 110B on the inside of the passenger compartment, and a spacer 120 provided throughout the inside of the through-hole 110C and the main surface 110B on the inside of the passenger compartment and holding a fixing shaft 52 of an antenna device 50 having a mounting surface 51A abutting against the main surface 110A on the outside of the passenger compartment, inside the through-hole 110C. Thus, in a state where the mounting surface 51A of the antenna device 50 abuts against the main surface 110A on the outside of the passenger compartment, the fixing shaft 52 is held by the spacer 120 provided throughout the inside of the through-hole 110C and the main surface 110B on the inside of the passenger compartment, so that the main surface 110A on the outside of the passenger compartment of the glass plate 110 abuts against the mounting surface 51A of the antenna device 50 with a larger area, and the antenna device 50 can be stably fixed.
[0088] Therefore, the vehicle window glass 100 capable of stably fixing the antenna device 50 can be provided.
[0089] Further, the spacer 120 can have a first portion 121 provided inside the through-hole 110C, and a second portion 122 abutting against the main surface 110B on the inside of the passenger compartment. By using the spacer 120 having the first portion 121 and the second portion 122, the vehicle window glass 100 capable of more stably fixing the antenna device 50 can be provided. Further, by embedding the first portion 121 inside the through-hole 110C, a waterproof countermeasure between the first portion 121 and the through-hole 110C, and suppression of breakage of a portion of an edge (rim) of the through-hole 110C in the glass plate 110, and the like can be achieved.
[0090] Further, the second portion 122 can be flat plate-shaped. By making the second portion 122 flat plate-shaped, the spacer 120 can be stably mounted to the main surface 110B on the inside of the passenger compartment. Therefore, in a state where the mounting surface 51A of the antenna device 50 abuts against the main surface 110A on the outside of the passenger compartment, the fixing shaft 52 is held by the spacer 120 stably fixed to the glass plate 110, so that the antenna device 50 can be more stably fixed.
[0091] Further, it can be that the spacer 120 further has through-holes 121A and 122A (second through-holes) through the first portion 121 and the second portion 122 in a through direction of the through-hole 110C, and the fixing shaft 52 is inserted into the through-holes 121A and 122A. By inserting the fixing shaft 52 into the through-holes 121A and 122A of the first portion 121 and the second portion 122, the antenna device 50 can be more stably fixed while the swing and the like of the antenna device 50 are effectively suppressed.
[0092] Further, the opening shape of the through holes 121A and 122A can be circular or rectangular, as long as it is a shape that matches the shape in plan view of the fixing shaft 52. Further, the shape in plan view of the fixing shaft 52 can be the shape of the fixing shaft 52 alone, or can include the shape of the fixing shaft 52 and the shape of the protruding portion of the coaxial cable. By inserting the fixing shaft 52, which has a shape that matches the shape of the through holes 121A and 122A, into the through holes 121A and 122A, the swaying of the antenna device 50 and the like can be effectively suppressed, and the antenna device 50 can be more stably fixed.
[0093] Further, a metal plate 130 can be included, which is arranged so as to overlap the surface of the second portion 122 on the side opposite the first portion 121, and has a through hole 130A (third through hole) through which the fixing shaft 52 is inserted. The use of the metal plate 130 can cause the fastening force when the antenna device 50 is fastened to the glass plate 110 by the fixing shaft 52 not to act directly on the spacer 120, and can distribute the fastening force. Thus, the antenna device 50 can be more firmly and stably fixed to the glass plate 110 with a stronger fastening force, and the breakage of the glass plate 110 caused by the fastening force can be suppressed.
[0094] Further, the metal plate 130 can be connected to the reference potential point. The metal plate 130 can shield the noise that comes from the inside of the passenger compartment, and the antenna characteristics of the antenna device 50 can be improved.
[0095] The spacer 120 can be made of resin or metal. By firmly holding the fixing shaft 52 with the spacer 120 made of resin or metal, the antenna device 50 can be more stably fixed.
[0096] The window glass for a vehicle with an antenna has an antenna device 50 having a mounting surface 51A and a fixing shaft 52 protruding from the mounting surface 51A, a glass plate 110 mounted to a window frame 11 of a vehicle body 10 and having a through hole 110C through which a main surface 110A on the outside of a passenger compartment and a main surface 110B on the inside of the passenger compartment, and a spacer 120 provided throughout the inside of the through hole 110C and the main surface 110B on the inside of the passenger compartment and holding the fixing shaft 52 of the antenna device 50 having the mounting surface 51A abutting against the main surface 110A on the outside of the passenger compartment in the inside of the through hole 110C. In this way, the fixing shaft 52 is held by the spacer 120 provided throughout the inside of the through hole 110C and the main surface 110B on the inside of the passenger compartment in a state where the mounting surface 51A of the antenna device 50 abuts against the main surface 110A on the outside of the passenger compartment, and thus the antenna device 50 can be stably fixed.
[0097] Therefore, it is possible to provide the antenna-equipped vehicle window glass 100A capable of stably fixing the antenna device 50 on the vehicle window glass 100.
[0098] The vehicle 1 includes a vehicle body 10 and a vehicle window glass 100 having a glass plate 110 mounted on a window frame 11 of the vehicle body 10 and having a through-hole 110C between a main surface 110A on the outside of a passenger compartment and a main surface 110B on the inside of the passenger compartment, and a spacer 120 provided throughout the inside of the through-hole 110C and the main surface 110B on the inside of the passenger compartment and holding a fixing shaft 52 of an antenna device 50 having a mounting surface 51A abutting against the main surface 110A on the outside of the passenger compartment in the inside of the through-hole 110C. Thus, in a state where the mounting surface 51A of the antenna device 50 abuts against the main surface 110A on the outside of the passenger compartment, the fixing shaft 52 is held by the spacer 120 provided throughout the inside of the through-hole 110C and the main surface 110B on the inside of the passenger compartment, and thus it is possible to stably fix the antenna device 50.
[0099] Therefore, it is possible to provide the vehicle 1 capable of stably fixing the antenna device 50 on the vehicle window glass 100.
[0100] <Vehicle window glass 100M1 of the first modification of the embodiment>
[0101] Figure 3 is a drawing illustrating an example of the vehicle window glass 100M1 of the first modification of the embodiment in an exploded state.
[0102] The vehicle window glass 100M1 includes the glass plate 110, the spacer 120M, and the metal plate 130. The vehicle window glass 100M1 has a structure in which the spacer 120 of the vehicle window glass 100 of the embodiment is replaced with the spacer 120M. Other structures are the same as those of the vehicle window glass 100 of the embodiment, and thus the same structural elements are denoted by the same symbols, and the description thereof is omitted.
[0103] Figure 3 In the middle, the antenna device 50, the glass plate 110, the spacer 120M, and the metal plate 130 are illustrated from an oblique upper side. Figure 3 The main surface 110A on the outside of the passenger compartment of the glass plate 110 is illustrated.
[0104] <Spacer 120M>
[0105] The spacer 120M has a first portion 121M and a second portion 122M. The second portion 122M includes a cylindrical portion 122M1 and a plate-shaped portion 122M2. The cylindrical portion 122M1 can be separated from the plate-shaped portion 122M2 and formed integrally with the first portion 121M. Thus, the spacer 120M has a structure that can be separated into the first portion 121M and the cylindrical portion 122M1 and the plate-shaped portion 122M2. The spacer 120M is preferably made of resin, but can be made of a relatively soft metal such as aluminum.
[0106] The cylindrical portion 122M1 is a cylindrical portion around the through-hole 122A in the second portion 122 of the spacer 120 of the vehicle window glass 100 of the embodiment. The plate-shaped portion 122M2 is a portion remaining after the cylindrical portion 122M1 is removed from the second portion 122 of the spacer 120 of the vehicle window glass 100 of the embodiment, and has a through-hole 122M2A that accommodates the cylindrical portion 122M1.
[0107] By inserting the cylindrical portion 122M1 into the through-hole 122M2A, the shape of the spacer 120M in a combined state of the first portion 121M and the cylindrical portion 122M1 and the plate-shaped portion 122M2 is the same as the shape of the spacer 120 of the vehicle window glass 100 of the embodiment.
[0108] The first portion 121M is a cylindrical portion protruding upward from the upper surface of the plate-shaped portion 122M2 of the second portion 122M in a state where the cylindrical portion 122M1 is accommodated in the through-hole 122M2A of the plate-shaped portion 122M2, and is formed integrally with the cylindrical portion 122M1, as shown in FIG. 12B. Figure 3 The first portion 121M is embedded in the inside of the through-hole 110C.
[0109] The first portion 121M has a through-hole 121MA. The through-hole 121MA is the same as the through-hole 121A of the first portion 121 of the spacer 120 of the vehicle window glass 100 of the embodiment. In the through-hole 121MA, the base 52A of the antenna device 50 is accommodated (see FIG. 10 and FIG. 11). Figure 1B and Figure 2A ).
[0110] The cylindrical portion 122M1 has a through-hole 122M1A that communicates with the through-hole 121MA. The through-holes 121MA and 122M1A are an example of the second through-hole. The through-hole 122M1A is the same as the through-hole 122A of the second portion 122 of the spacer 120 of the vehicle window glass 100 of the embodiment.
[0111] As described above, the spacer 120M can be separated into the first portion 121M and the cylindrical portion 122M1, and the plate-shaped portion 122M2. Therefore, when the antenna device 50 is mounted to the glass plate 110, for example, the first portion 121M is fitted into the through-hole 110C of the glass plate 110, and the fixing shaft 52 is brought into a state of passing through the through-holes 121MA and 122M1A of the first portion 121M and the cylindrical portion 122M1. In this state, the cylindrical portion 122M1 can be inserted into the through-hole 122M2A of the plate-shaped portion 122M2.
[0112] That is, in a state where the first portion 121M is fitted into the through-hole 110C of the glass plate 110, and the first portion 121M and the cylindrical portion 122M1 are mounted to the antenna device 50 side, the cylindrical portion 122M1 is inserted into the through-hole 122M2A of the plate-shaped portion 122M2. By assembling the nut 53 to the lower end of the fixing shaft 52, the antenna main body 51 can be fastened to the glass plate 110.
[0113] <Effects>
[0114] The vehicle window glass 100M1 of the first modification example of the embodiment includes the spacer 120M which can be separated into the first portion 121M and the cylindrical portion 122M1, and the plate-shaped portion 122M2. The combined state of the first portion 121M and the cylindrical portion 122M1, and the plate-shaped portion 122M2 is the same as the spacer 120 of the vehicle window glass 100 of the embodiment.
[0115] Thus, in a state where the mounting surface 51A of the antenna device 50 is in contact with the main surface 110A on the vehicle compartment outside, the fixing shaft 52 is held by the spacer 120M provided throughout the inside of the through-hole 110C and the main surface 110B on the vehicle compartment inside, the main surface 110A of the glass plate 110 on the vehicle compartment outside is in contact with the mounting surface 51A of the antenna device 50 with a larger area, and the antenna device 50 can be stably fixed.
[0116] Therefore, it is possible to provide the vehicle window glass 100M1 which can stably fix the antenna device 50.
[0117] In addition, by being separable into the first portion 121M and the cylindrical portion 122M1, and the plate-shaped portion 122M2, it is possible to mount the antenna device 50 to the glass plate 110 after the fixing shaft 52 is mounted to the first portion 121M and the cylindrical portion 122M1.
[0118] <Vehicle Window Glass 100M2 of the Second Modification Example of the Embodiment>
[0119] Figure 4A is a drawing illustrating an example of a cross-sectional structure of the vehicle window glass 100M2 of the second modification example of the embodiment.Figure 4B and Figure 4C is a view showing an example of a disassembled state of the vehicle window glass 100M2.
[0120] The vehicle window glass 100M2 includes the glass sheet 110, the spacer 220, and the metal plate 130. The vehicle window glass 100M2 has a structure in which the spacer 120 of the vehicle window glass 100 of the embodiment is replaced with the spacer 220. Figures 4A-4C In the second modification example, the metal plate 130 can be a circular ring member having the same size as the top-down dimension of the spacer 220, but in the embodiment, the metal plate 130 is a circular ring member having a smaller size than the top-down dimension of the spacer 220. Figure 2A In the second modification example, the metal plate 130 can be a circular ring member having the same size as the top-down dimension of the spacer 220, but in the embodiment, the metal plate 130 is a circular ring member having a smaller size than the top-down dimension of the spacer 220.
[0121] The antenna device 50M is mounted on the vehicle window glass 100M2. The antenna device 50M has the holding member 55 in addition to the antenna main body 51, the fixing shaft 52, and the nut 53.
[0122] Figure 4A An example of a cross-sectional structure in a state in which the antenna device 50M is mounted on the vehicle window glass 100M2 is shown. In the second modification example of the embodiment, the vehicle window glass 100A with antenna includes the vehicle window glass 100M2 and the antenna device 50M.
[0123] Figure 4B In the second modification example, the glass sheet 110, the spacer 220, and the metal plate 130 are shown from an oblique upper side. In addition, Figure 4B The main surface 110A of the glass sheet 110 on the outside of the passenger compartment is shown, and the fixing shaft 52, the nut 53, and the base 55A of the holding member 55 of the antenna device 50M are shown.
[0124] Figure 4C In the second modification example, the glass sheet 110, the spacer 220, and the metal plate 130 are shown from an oblique lower side. Figure 4C The main surface 110B of the glass sheet 110 on the inside of the passenger compartment (-Z direction side) is shown, and the fixing shaft 52, the nut 53, and the holding member 55 of the antenna device 50M are shown.
[0126] <holding member 55>
[0127] The holding member 55 is mounted on the mounting surface 51A of the antenna main body 51 and is located between the mounting surface 51A and the main surface 110A on the outside of the passenger compartment when the antenna device 50M is mounted on the glass sheet 110. The holding member 55 is a member that holds the antenna main body 51 on the glass sheet 110.
[0129] The holding member 55 has a base portion 55A, a plate portion 55B, a convex portion 55C, a circular ring convex portion 55D, and a through-hole 55E. The holding member 55 is preferably made of resin, but can also be made of a comparatively soft metal such as aluminum.
[0131] The base portion 55A is a cylindrical portion located at the center portion of the holding member 55. In a state in which the antenna device 50M is mounted to the glass plate 110, the lower surface of the base portion 55A abuts against the surrounding portion of the through-hole 110C in the main surface 110A on the outside of the vehicle cabin of the glass plate 110. The plate portion 55B is a plate-shaped (disc-shaped) portion that is circular in plan view, and is located on the upper side of the base portion 55A.
[0133] The convex portion 55C is a cylindrical portion that protrudes downward from the central portion of the lower surface of the base portion 55A. The diameter of the convex portion 55C is smaller than the diameter of the base portion 55A. The convex portion 55C coincides with the central axis of the base portion 55A. The size in plan view of the convex portion 55C coincides with the size in plan view of the through-hole 110C of the glass plate 110. By embedding the convex portion 55C inside the through-hole 110C, the space between the convex portion 55C and the through-hole 110C can be sealed, enabling a waterproof countermeasure to be implemented.
[0135] The circular ring convex portion 55D is a circular ring-shaped convex portion provided to the lower surface of the plate portion 55B, and is formed in a ridge shape so as to surround the base portion 55A. The cross-sectional shape of the circular ring convex portion 55D is a reverse triangular shape as an example. The cross-sectional shape of the circular ring convex portion 55D is not limited to a reverse triangular shape, and can be a semicircular shape or the like, for example.
[0137] The length in the Z direction in which the circular ring convex portion 55D protrudes from the lower surface of the plate portion 55B is equal to the length in the Z direction in which the base portion 55A protrudes from the lower surface of the plate portion 55B as an example, but the length in the Z direction of the circular ring convex portion 55D can be longer than the length in the Z direction of the base portion 55A. In the case in which the length in the Z direction of the circular ring convex portion 55D is longer than the length in the Z direction of the base portion 55A, the circular ring convex portion 55D is in close contact with the main surface 110A on the outside of the vehicle cabin of the glass plate 110, and thus the portion inside the circular ring convex portion 55D in plan view can be sealed.
[0139] As shown in Figs. 17 and 18, the through-hole 55E passes through the center in plan view of the holding member 55 in the Z direction. The fixing shaft 52 passes through the through-hole 55E. Figure 4A Figure 4B
[0141] <Spacer 220>
[0142] The spacer 220 is a ring-shaped member, for example, and has a through-hole 220A that penetrates in the Z direction. The spacer 220 is not limited to a ring shape, but can be a ring-shaped member. The lower surface dimension of the spacer 220 is substantially equal to the base portion 55A of the holding member 55, for example, but the spacer 220 can be larger or smaller than the base portion 55A.
[0144] The lower surface dimension of the through-hole 220A is equal to the dimension of the protrusion 55C, for example. By inserting the lower end of the protrusion 55C halfway into the through-hole 220A, the space between the protrusion 55C and the through-hole 220A can be sealed, and a waterproof countermeasure can be implemented. The protrusion 55C can be located inside the through-hole 110C of the glass plate 110, and the length in the Z direction can be shortened to a degree that does not reach the inside of the through-hole 220A.
[0145] <Assembling the antenna device 50M to the vehicle window glass 100>
[0146] The holding member 55 is disposed below the antenna main body 51, the protrusion 55C is inserted into the through-hole 110C of the glass plate 110, and the metal plate 130 is disposed below the spacer 220 in a state in which the lower end of the protrusion 55C is inserted into the through-hole 220A of the spacer 220. The nut 53 is assembled to the lower end of the fixing shaft 52, and thus the antenna main body 51 can be fastened to the glass plate 110.
[0147] <Effects>
[0148] The vehicle window glass 100M2 includes a glass plate 110, an antenna main body 51, a holding member 55, and a spacer 220. The glass plate 110 is mounted to a window frame 11 of a vehicle body 10 and has a through-hole 110C that penetrates between a main surface 110A on the outside of a passenger compartment and a main surface 110B on the inside of the passenger compartment. The holding member 55 is disposed between the antenna main body 51 and the main surface 110A on the outside of the passenger compartment and has a protrusion 55C that protrudes into the through-hole 110C. The spacer 220 holds a fixing shaft 52 of an antenna device 50M having the fixing shaft 52 extending from a front end of the protrusion 55C and abuts against the main surface 110B on the inside of the passenger compartment.
[0150] Thus, in a state in which the antenna main body 51 is stably mounted to the main surface 110A on the outside of the passenger compartment by the holding member 55, the fixing shaft 52 is held by the spacer 220 that abuts against the main surface 110B on the inside of the passenger compartment, and thus the antenna device 50 can be stably fixed.
[0151] Therefore, it is possible to provide a vehicle window glass 100M2 that can stably fix an antenna device 50.
[0152] Vehicle window glass 100M3 of the third modification of the embodiment
[0153] Figure 5 is a drawing showing an example of the cross-sectional structure of the vehicle window glass 100M3 of the third modification of the embodiment. Figure 5 is a drawing showing an example of the cross-sectional structure corresponding to Figure 2A .
[0154] The vehicle window glass 100M3 includes the glass plate 110, the spacer 120M3, and the metal plate 130M3. The following describes the difference from the structure of the vehicle window glass 100 shown in Figure 2A .
[0155] The vehicle window glass 100M3 differs from the vehicle window glass 100 shown in Figure 2A in that it has a structure corresponding to the anchor bolt 52M and the coaxial cable 60. The anchor bolt 52M and the base 52A are an example of a fixed shaft.
[0156] The through hole 121A of the spacer 120M3 is larger than the through hole 121A of the spacer 120 shown in Figure 2A in plan view, and the coaxial cable 60 also passes therethrough in addition to the base 52A. The coaxial cable 60 has a core wire connected to an antenna element provided inside the antenna main body 51 and a shield wire connected to a ground layer. In addition, the through hole 122A of the spacer 120M3 is provided with two corresponding to the anchor bolt 52M and the coaxial cable 60, and communicates with the lower side of one through hole 121A. In addition, the through hole 121A can also be divided into two corresponding to the base 52A and the coaxial cable 60, and the two through holes 121A each communicate with one through hole 122A.
[0157] In addition, the metal plate 130M3 has two through holes 130A corresponding to the anchor bolt 52M and the coaxial cable 60. The two through holes 130A coincide in position with the two through holes 122A through which the base 52A and the coaxial cable 60 pass.
[0158] When fixing the antenna device 50 to the vehicle window glass 100M3, first, the upper end of the anchor bolt 52M is fusion-fixed to the base 52A, and in a state in which the positions of the spacer 120M3 and the metal plate 130M3 are aligned, the coaxial cable 60 and the anchor bolt 52M are inserted from above into the through holes 130A and 122A of one side, and the base 52A and the coaxial cable 60 pass through the through hole 121A. Then, the anchor of the anchor bolt 52M is spread on the lower surface of the spacer 120M3, and thus the antenna device 50 can be fixed to the vehicle window glass 100M3.
[0159] The opening shape of the through-holes 121A and 122A of such a spacer 120 is a shape that coincides with the shape in plan view of the base 52A, the anchor bolt 52M, and the coaxial cable 60. More specifically, the opening shape of the through-hole 121A is a shape that coincides with the shape in plan view of the base 52A and the coaxial cable 60, and the opening shape of the through-hole 122A is a shape that coincides with the shape in plan view of the anchor bolt 52M and the coaxial cable 60.
[0160] Thus, in a state in which the mounting surface 51A of the antenna device 50 is in contact with the main surface 110A on the vehicle cabin outside, the anchor bolt 52M and the base 52A are held by the spacer 120M3 provided throughout the inside of the through-hole 110C and the main surface 110B on the vehicle cabin inside, and thus the main surface 110A of the glass panel 110 on the vehicle cabin outside is in contact with the mounting surface 51A of the antenna device 50 with a larger area, and the antenna device 50 can be stably fixed.
[0161] Therefore, it is possible to provide the vehicle window glass 100M3 capable of stably fixing the antenna device 50. In addition, it is also possible to provide the vehicle window glass 100M3 capable of stably fixing the antenna device 50 in a state in which the coaxial cable 60 also passes through in addition to the anchor bolt 52M and the base 52A. Furthermore, it is also possible to include a claw or the like structure for temporarily fixing the coaxial cable 60 inside the through-hole 121A or 122A.
[0162] The above describes an example vehicle window glass, a vehicle window glass with an antenna, and a vehicle according to the present disclosure, but the present disclosure is not limited to the specifically disclosed embodiments, and various modifications or changes can be made without departing from the scope of the claims.
[0163] In addition, this international application is an application claiming priority based on Japanese Patent Application No. 2023-144336 filed on September 6, 2023, the entire contents of which are hereby incorporated by reference into this international application.
