Abstract
Description
Glass plate module
[0001] The present disclosure relates to a glass plate module.
[0002] Japanese Patent Application Laid-Open No. 2023-152832 discloses a glass plate laminate including a first glass plate, a plate-like body, and an intermediate film positioned between the first glass plate and the plate-like body, a mount portion that fixes a vibrator to the glass plate laminate, and a vibrator that generates vibrations, namely, a glass diaphragm with a vibrator.
[0003] By the way, the glass plate may become hot when it is installed outdoors and exposed to sunlight. When the glass plate becomes hot, heat is transferred to acoustic output members such as a vibrator attached to the glass plate. When heat is transferred to the acoustic output member, there is a possibility of malfunction or damage.
[0004] In consideration of the above facts, an object of the present disclosure is to obtain a glass plate module that can suppress the temperature rise of an acoustic output member and suppress malfunction or damage of the acoustic output member.
[0005] The glass plate module according to the present disclosure includes a glass plate that separates the interior and exterior of a vehicle, and an acoustic output member attached to the surface on the interior side of the glass plate. The glass plate has an inner glass plate, an outer glass plate provided on the outdoor side of the inner glass plate, an intermediate layer provided between the inner glass plate and the outer glass plate, and a heat ray reflection portion provided between the inner glass plate and the outer glass plate. The acoustic output member is provided so as to overlap the heat ray reflection portion when viewed from a direction perpendicular to the plate surface of the glass plate.
[0006] As described above, the glass plate module according to the present disclosure has an excellent effect of suppressing the temperature rise of the acoustic output member and suppressing malfunction or damage of the acoustic output member.

It is a longitudinal sectional view showing a roof glass and a glass plate module according to the second embodiment of the present disclosure. It is a longitudinal sectional view showing a roof glass and a glass plate module according to the third embodiment of the present disclosure.
[0008] Hereinafter, embodiments of the glass plate module according to this disclosure will be described with reference to Figures 1 to 4. In each figure, arrows FR indicate the front of the vehicle in the longitudinal direction, arrows IN indicate the inward direction in the vehicle width direction, and arrows UP indicate the upper side of the vehicle in the vertical direction. In the following description, when simply referred to as "longitudinal direction," "width direction," and "vertical direction," they refer to the longitudinal direction, width direction, and vertical direction of the vehicle, respectively.
[0009] Furthermore, while the following description focuses on the application of the glass plate module to vehicle windows, the glass plate module described herein may be applied to other moving objects such as airplanes, helicopters, ships, and trains, not just vehicles. It may also be applied to the windows of buildings and other structures.
[0010] [First Embodiment] First, the glass plate module 10 according to the first embodiment will be described with reference to Figures 1 and 2.
[0011] As shown in Figure 1, in this embodiment, for example, the glass plate module 10 is applied to the roof glass 20 of a vehicle. As shown in Figure 2, the glass plate module 10 comprises a roof glass (glass plate) 20, a vibrator (sound output member) 30 that vibrates the roof glass 20 to function as a speaker, and an adhesive layer 40 that adheres the roof glass 20 and the vibrator 30 together.
[0012] (Roof Glass) The roof glass 20 constitutes the vehicle's window glass. The roof glass 20 is located on the upper side of the vehicle. The roof glass 20 defines a portion of the upper end of the passenger compartment (interior) S1. As shown in Figure 1, the roof glass 20 is formed, for example, in a substantially trapezoidal shape with the front-to-rear direction of the vehicle as its longitudinal direction. The roof glass 20 may also be shaped to extend from the front windshield located on the front side of the vehicle to the rear glass located on the rear side of the vehicle (panoramic roof).
[0013] As shown in Figure 2, the roof glass 20 separates the passenger compartment S1 from the outside space S2 in a portion that defines the upper end of the passenger compartment S1. The roof glass 20 is fixed to the roof panel 11 in a manner that prevents it from sliding. As shown in Figure 2, the end of the roof glass 20 in the vehicle width direction is fixed to the roof panel 11 via a fixing member 13. The fixing member 13 is attached to the lower surface of the end of the roof glass 20 in the vehicle width direction. For example, an adhesive such as urethane resin can be used as the fixing member 13.
[0014] The outer perimeter 20A of the roof glass 20 is covered from below by an interior panel (not shown). The outer perimeter 21 refers to the ends of the roof glass 20 in the vehicle width direction and the vehicle longitudinal direction.
[0015] As shown in Figure 2, the roof glass 20 is made of laminated glass. The roof glass 20 has an inner glass plate 21 provided on the side of the passenger compartment S1, an outer glass plate 22 provided on the side of the passenger compartment outside space S2 that is closer to the inner glass plate 21, and an intermediate layer 23 provided between the inner glass plate 21 and the outer glass plate 22.
[0016] The roof glass 20 is made of laminated glass, in which two glass plates (inner glass plate 21 and outer glass plate 22) are bonded together with a resin intermediate layer 23. The roof glass 20 may consist of two untempered glass plates (inner glass plate 21 and outer glass plate 22), one of which may be tempered glass, or both may be tempered glass. If both are tempered glass, both may be air-cooled tempered glass, both may be chemically tempered glass, or one may be air-cooled tempered glass and the other may be chemically tempered glass.
[0017] (Glass Plates) The inner glass plate 21 and the outer glass plate 22 are made of transparent or translucent inorganic glass. Examples of inorganic glass include soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass. The inner glass plate 21 and the outer glass plate 22 may also be made of organic glass. Examples of organic glass include PMMA (polymethyl methacrylate) resin, PC (polycarbonate) resin, PS (polystyrene) resin, PET (polyethyleneterephthalate) resin, PVC (polyvinyl chloride) resin, and cellulose resin.
[0018] The thickness of the inner glass plate 21 and the outer glass plate 22 is preferably 0.5 mm or more, more preferably 1.0 mm or more, and even more preferably 1.5 mm or more. The thicknesses of the inner glass plate 21 and the outer glass plate 22 may be the same or different, but from the viewpoint of stabilizing sound pressure, the same thickness is preferred. Furthermore, the total thickness of the roof glass 20 is preferably 1.0 mm or more, more preferably 2.0 mm or more, and even more preferably 3.0 mm or more. Also, from the viewpoint of weight reduction, it is preferably 10.0 mm or less, more preferably 8.0 mm or less, and even more preferably 6.0 mm or less.
[0019] Furthermore, the inner glass plate 21 and the outer glass plate 22 may be colored glass baked with blue, red, green, gray, etc., or they may be privacy glass. Privacy glass is glass with lower transparency than green glass and clear glass, and is also called dark gray glass. In the roof glass 20, the privacy glass is Fe ２ O ３ This can be achieved by adjusting the total iron content converted to iron. The visible light transmittance of privacy glass can be adjusted to approximately 40-50% when the plate thickness is 1.8 mm, and approximately 30-45% when the plate thickness is 2.0 mm.
[0020] (Interlayer) The intermediate layer 23 can be exemplified by a resin film containing a thermosetting adhesive material such as a transparent polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) resin film, silicone (PDMS), polyurethane, fluorine, polyethylene terephthalate, or polycarbonate. In addition, materials that enhance sound insulation, materials that enhance rigidity, and materials that absorb ultraviolet and infrared rays may be added to the intermediate layer. The intermediate layer 23 may be a liquid or gel intermediate layer. Specific examples of liquid intermediate layers include water, oil, organic solvents, liquid polymers, ionic liquids, and mixtures thereof. More specifically, examples include propylene glycol, dipropylene glycol, tripropylene glycol, straight silicone oil (dimethyl silicone oil, methylphenyl silicone oil, methyl hydrogen silicone oil), modified silicone oil, acrylic acid polymers, liquid polybutadiene, glycerin paste, fluorine-based solvents, fluorine-based resins, acetone, ethanol, xylene, toluene, water, mineral oil, and mixtures thereof. In particular, it is preferable to include at least one selected from the group consisting of propylene glycol, dimethyl silicone oil, methylphenyl silicone oil, methyl hydrogen silicone oil, and modified silicone oil, and it is more preferable to have propylene glycol or silicone oil as the main component. Specifically, examples of gel-like intermediate layers include carbon-based, fluorine-based, or silicone-based polymer materials. Specifically, examples include ABS, AES, AS, CA, CN, CPE, EEA, EVA, EVOH, IO, PMMA, PMP, PP, PS, PVC, RB, TPA, TPE, TPEE, TPF, TPO, TPS, TPU, TPVC, AAS, ACS, PET, PPE, PA6, PA66, PBN, PBT, PC, POM, PPO, ETFE, FEP, LCP, PEEK, PEI, PES, PFA, PPS, PSV, PTFE, PVDF, silicone, polyurethane, PI, PF, PVB, TAC, polyolefin, acrylic and its copolymer resins, etc. Alternatively, composite materials combining the above materials may be used. The above materials may be used individually or in combination of two or more types.Furthermore, tackifiers and plasticizers may be included to provide adhesion. The thickness of the intermediate layer 23 may be, for example, 0.1 [μm] to 3.0 [mm], 1.0 [μm] to 2.8 [mm], or 3.0 [μm] to 2.6 [mm]. If the roof glass 20 is laminated glass, a dimmable film that electrically varies the visible light transmittance may be sandwiched between the two glass plates. Examples of dimmable films that can be used include TN (Twisted Nematic) type liquid crystal film, VA (Vertical Alignment) type liquid crystal film, polymer dispersed liquid crystal (PDLC) film, suspended particle device (SPD) film, polymer network liquid crystal (PNLC) film, guest host liquid crystal film, electrochromic material, and photochromic material. Glass that displays an image on part or all of the glass is also conceivable. As a method for displaying images, a liquid crystal film may be sandwiched between the glass plates. Alternatively, a projection screen film may be sandwiched between the glass plates. Furthermore, some or all of the glass may be equipped with film-like solar cell elements for generating electricity from sunlight. To ensure visibility as a vehicle window, it is generally preferable to use transparent films that have excellent transparency. These functions may be imparted not only by sandwiching the film between the glass plates, but also by directly microfabrication, printing, transfer, and application of the film to the glass surface, as long as the glass speaker function is not lost.
[0021] (Light-shielding layer) As shown in Figure 1, the outer periphery 20A of the roof glass 20 is provided with an inner light-shielding layer 25 and an outer light-shielding layer 26 of a predetermined width, formed from a color ceramic layer such as black, dark, or white, or a color ink layer printed with organic or inorganic ink. Note that this disclosure may also be applied to a structure that does not have both or either the inner light-shielding layer 25 and the outer light-shielding layer 26. The inner light-shielding layer 25 and the outer light-shielding layer 26 have higher heat dissipation than the inner glass plate 21 and the outer glass plate 22.
[0022] The roof glass 20 is structured in such a way that the transducer 30 and other components are difficult to see from outside the vehicle due to the inner light-shielding layer 25 and the outer light-shielding layer 26. As shown in Figure 1, the inner light-shielding layer 25 and the outer light-shielding layer 26 are provided continuously around the outer edge of the roof glass 20, but there may be areas where the inner light-shielding layer 25 and the outer light-shielding layer 26 are not provided in at least a portion of the roof glass 20.
[0023] The inner light-shielding layer 25 is provided on the surface (specifically, the underside) of the roof glass 20. Specifically, it is provided on the underside of the outer peripheral portion 21A of the inner glass plate 21 of the roof glass 20. The inner end of the inner light-shielding layer 25 in the vehicle width direction is located inward in the vehicle width direction from the interior panel 15. The width of the inner light-shielding layer 25 is greater than the width of the outer light-shielding layer 26.
[0024] The outer light-shielding layer 26 is provided on the lower surface of the outer peripheral portion 22A of the outer glass plate 22. That is, the outer light-shielding layer 26 is provided between the outer glass plate 22 and the intermediate layer 23. The inner end of the outer light-shielding layer 26 in the vehicle width direction is located outside the interior panel 15 in the vehicle width direction.
[0025] If the roof glass 20 is equipped with conductive wires (e.g., antennas, etc.) formed by printing and baking a paste containing a conductive metal (e.g., silver paste, etc.) onto the main surface on the interior side of the vehicle, it is preferable that the transducer 30 be mounted so as not to overlap with the conductive wires.
[0026] Furthermore, a coating film may be formed on the roof glass 20. The coating film may include a Low-E (Low Emissivity) film, an AG (Anti-Glare) film, an AR (Anti-Reflection) film, an AF (Anti-Fingerprint) film, a UV (ultraviolet) cut film, an anti-fogging film, an anti-mold film, and a water-repellent film.
[0027] (Coating) As shown in Figure 2, the lower surface of the outer glass plate 22 (the surface on the interior S1 side) is provided with a heat-reflective coating (heat-reflective portion) 28. The coating 28 is provided so as not to overlap with the outer light-shielding layer 26. The coating 28 is provided on the inside of the outer light-shielding layer 26 in the vehicle width direction. The coating 28 may also be provided so as to overlap with the outer light-shielding layer 26. Furthermore, the coating 28 is provided so as to overlap with the inner light-shielding layer 25 when viewed from the top and bottom.
[0028] The coating 28 is formed from a material containing silver, for example. However, the material of the coating 28 is not particularly limited as long as it is formed to have a heat reflection function (infrared reflection function). The coating 28 may be formed from a single layer or from multiple layers. Furthermore, the coating 28 may have any configuration as long as it is formed to have a heat reflection function (infrared reflection function). The coating 28 may contain at least one selected from the group including silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), and ion-doped metal oxides. Examples of ion-doped metal oxides include indium tin oxide (ITO), fluorine-doped tin oxide (FTO), aluminum-doped zinc oxide (AZO), and gallium zinc oxide (GZO). The coating 28 is formed by applying it to the lower surface of the outer glass plate 22 by methods such as vacuum deposition, sputtering, CVD, and spraying. The thickness of the coating 28 is not particularly limited, but for example, it is in the range of 100 nm to 1000 nm.
[0029] (Vibrator) The vibrator 30 is bonded to the lower surface of the inner glass plate 21. More specifically, the vibrator 30 is bonded to the lower surface of the inner light-shielding layer 25 attached to the inner glass plate 21 by an adhesive layer 40. The vibrator 30 is positioned so as to overlap with the coating 28 when viewed from a direction perpendicular to the surface of the roof glass 20 (in this embodiment, the up and down direction).
[0030] The transducer 30 is connected to a power source via a cable (not shown) and is an actuator that vibrates the roof glass 20 in response to an input electrical signal. In this embodiment, the transducer 30 is, as an example, a voice coil motor including a coil section and a magnetic circuit. One of the coil section and the magnetic circuit is fixed to the roof glass 20, while the other is arranged to be movable relative to the roof glass 20. When current flows through the coil section, vibration is generated by the interaction between the coil section and the magnetic circuit, causing the roof glass 20 to vibrate (vibrate). The direction of vibration is in the thickness direction of the transducer. Note that the transducer is not limited to a voice coil motor; any actuator capable of transmitting the desired vibration to the roof glass 20 can be used, such as a piezo actuator or other actuators besides a voice coil motor.
[0031] (Adhesive layer) The adhesive layer 40 is provided between the roof glass 20 and the transducer 30. More specifically, the adhesive layer 40 is provided between the high heat dissipation layer 28 and the transducer 30. The adhesive layer 40 adheres the high heat dissipation layer 28 and the transducer 30. As the adhesive layer 40, for example, adhesives such as urethane-based, phenol-based, butyl-based, synthetic rubber-based, acrylic-based, epoxy-based, silicone-based, and epoxy-modified silicone-based adhesives can be used, as well as adhesives that are thermosetting, moisture-curing, two-component-curing, ultraviolet-curing, visible-light-curing, or anaerobic-curing. In particular, epoxy-modified silicone-based adhesives that do not contain plasticizers are preferred because they are heat-resistant and have low decomposition properties.
[0032] The thickness of the adhesive layer 40 is such that a thinner layer can more effectively transmit vibrations from the transducer 19 to the roof glass 20. Therefore, it is acceptable for the adhesive layer 40 to be 12 mm or less, preferably 6.0 mm or less, more preferably 3.0 mm or less, more preferably 2.0 mm or less, more preferably 1.2 mm or less, particularly preferably 0.6 mm or less, and even more preferably 0.2 mm or less.
[0033] This embodiment provides the following effects. In this embodiment, a coating 28 is provided between the inner glass plate 21 and the outer glass plate 22. The coating 28 reflects heat rays from the outside. Therefore, the temperature rise of the roof glass 20 is suppressed in the area where the coating 28 is provided (more specifically, the area that overlaps with the coating 28 when viewed from a direction perpendicular to the surface of the roof glass 20 (up and down direction)). In this embodiment, the transducer 30 is provided in this area where the temperature rise is suppressed. Therefore, the heat transmitted from the roof glass 20 to the transducer 30 is also reduced. Thus, the temperature rise of the transducer 30 is suppressed, and malfunction or damage to the transducer 30 can be suppressed. Similarly, the heat transmitted from the roof glass 20 to the adhesive layer 40 is also reduced, so deterioration of the adhesive layer 40 can be suppressed.
[0034] Furthermore, in this embodiment, the transducer 30 is mounted in the region where the inner light-shielding layer 25 is provided. As a result, sunlight and the like are blocked by the inner light-shielding layer 25, so the temperature rise of the transducer 30 is suppressed. Therefore, malfunctions and damage to the transducer 30 can be suppressed. Similarly, the heat transferred from the roof glass 20 to the adhesive layer 40 is also reduced, so the deterioration of the adhesive layer 40 can be suppressed.
[0035] [Second Embodiment] Next, a glass plate module according to the second embodiment of the present disclosure will be described with reference to Figure 3. The glass plate module according to this embodiment differs from the first embodiment in that the position in which the vibrator 30 is provided is different. In the following description, only the differences from the first embodiment will be mentioned, and detailed descriptions of the same aspects as the first embodiment will be omitted. Also, the same reference numerals are used for components that are the same as in the first embodiment.
[0036] As shown in Figure 3, the transducer 30 of the glass plate module 60 according to this embodiment is provided in a region that does not overlap with the coating 28 when viewed from a direction perpendicular to the plate surface of the roof glass 20 (in this embodiment, the vertical direction). The transducer 30 is provided so as to be spaced apart from the coating 28 when viewed from the vertical direction. The distance L between the transducer 30 and the coating 28 is set to 200 mm or less when viewed from the vertical direction. More specifically, the distance L between the inner end of the transducer 30 in the vehicle width direction and the outer end of the coating 28 in the vehicle width direction is set to 200 mm or less. That is, the distance L between the transducer 30 and the end of the coating 28 closest to the transducer 30 is set to 200 mm or less. The transducer 30 is provided so as to overlap with the outer light-shielding layer 26 when viewed from the vertical direction.
[0037] This embodiment provides the following effects. In this embodiment, a coating 28 having a heat-reflective function is provided between the inner glass plate 21 and the outer glass plate 22. The coating 28 reflects heat rays from the outdoor space S2. Therefore, the temperature rise of the roof glass 20 is suppressed in the vicinity of the area where the coating 28 is provided (more specifically, the area that overlaps with the coating 28 when viewed from the vertical direction). In this embodiment, the distance L between the transducer 30 and the coating 28 is relatively short, at 200 mm. Therefore, the heat transmitted from the roof glass 20 to the transducer 30 is also reduced. Thus, the temperature rise of the transducer 30 is suppressed, and malfunctions and damage to the transducer 30 can be suppressed.
[0038] In this embodiment, the transducer 30 is provided so as to overlap with the outer light-shielding layer 26. As a result, sunlight and other light are blocked by the outer light-shielding layer 26, which suppresses the temperature rise of the transducer 30. Therefore, malfunctions and damage to the transducer 30 can be suppressed.
[0039] [Third Embodiment] Next, a glass plate module according to the third embodiment of the present disclosure will be described with reference to Figure 4. The glass plate module according to this embodiment differs from the first embodiment in that a film 50 is provided instead of a coating 28. In the following description, only the differences from the first embodiment will be mentioned, and detailed descriptions of the same aspects as the first embodiment will be omitted. Also, the same reference numerals are used for components that are the same as in the first embodiment.
[0040] As shown in Figure 3, the glass plate module 70 according to this embodiment is provided with a film 50 instead of a coating 28. The film 50 is enclosed in the intermediate layer 23. A portion of the film 50 is provided so as to overlap with the outer light-shielding layer 26 when viewed from the top and bottom. More specifically, the outer end of the film 50 in the vehicle width direction is provided so as to overlap with the outer light-shielding layer 26 when viewed from the top and bottom. In addition, the film 50 is provided so as to overlap with the inner light-shielding layer 25 when viewed from the top and bottom.
[0041] The transducer 30 is positioned so as to overlap with the film 50 when viewed from a direction perpendicular to the surface of the roof glass 20 (in this embodiment, the vertical direction).
[0042] In this embodiment, a film 50 is provided between the inner glass plate 21 and the outer glass plate 22. The film 50 reflects heat rays from the outside. Therefore, the temperature rise of the roof glass 20 is suppressed in the area where the film 50 is provided (more specifically, the area that overlaps with the film 50 when viewed from a direction perpendicular to the surface of the roof glass 20 (up and down direction)). In this embodiment, the transducer 30 is provided in this area where the temperature rise is suppressed. Therefore, the heat transmitted from the roof glass 20 to the transducer 30 is also reduced. Thus, the temperature rise of the transducer 30 is suppressed, and malfunction or damage to the transducer 30 can be suppressed. Similarly, the heat transmitted from the roof glass 20 to the adhesive layer 40 is also reduced, so the deterioration of the adhesive layer 40 can be suppressed.
[0043] Although the glass plate module according to the embodiment has been described above, the design of this disclosure can be modified as appropriate without departing from its essence.
[0044] For example, the second embodiment and the third embodiment may be combined. That is, when viewed from the vertical direction, the vibrator 30 and the film 50 may be provided so as not to overlap. In this case, as described in the second embodiment, the distance between the vibrator 30 and the film 50 is 200 mm or less when viewed from the vertical direction. Specifically, the distance between the inner end of the vibrator 30 in the vehicle width direction and the outer end of the film 50 in the vehicle width direction is 200 mm or less.
[0045] In each of the above embodiments, an example in which the acoustic output member is a vibrator has been described, but the present disclosure is not limited thereto. The acoustic output member may be any member that can be attached to the glass plate, and for example, it may be a speaker.
[0046] Also, although the glass plate module according to each of the above embodiments has been described as being applied to the roof glass 20 provided on the upper side of the vehicle, the present disclosure is not limited thereto. For example, the glass plate module may be applied to other window glasses of the vehicle, such as a rear glass arranged on the rear side of the vehicle, a side glass arranged on the side door of the vehicle, or a front window provided on the front side of the vehicle.
[0047] In each of the above embodiments, an example in which the vibrator 30 is directly adhered to the roof glass 20 has been described, but the present disclosure is not limited thereto. For example, the vibrator 30 may be attached to the roof glass 20 via a mounting member (not shown) or a long-shaped rod (not shown).
