Detailed Implementation

[0031] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0032] In one embodiment, such as Figure 1 As shown, this application proposes a glass assembly, including: a first glass layer 110, a first metal layer 120, an adhesive layer 130, a second glass layer 140, and a second metal layer 150 stacked sequentially, wherein the first metal layer 120 includes a first frequency selection region 121, and the second metal layer 150 includes a second frequency selection region 151.

[0033] Specifically, the first glass layer 110 serves as the outermost protective layer, resisting impacts, scratches, and chemical corrosion from the external environment, providing physical protection for the internal layer structure. The first metal layer 120 has a first frequency selection region 121, which can selectively reflect or transmit electromagnetic waves of specific frequencies. It can also integrate low-emissivity (Low-E) functionality for heat insulation, heating functionality for heating the glass assembly, or dimming functionality to adjust the transmittance of the glass assembly. An adhesive layer 130 is disposed between the first metal layer 120 and the second glass layer 140, bonding the first glass layer 110, the first metal layer 120, and the second glass layer 140 together, improving the stability of the glass assembly. In one embodiment, the adhesive layer 130 is one of polyvinyl butyral (PVB), polyethylene-vinyl acetate copolymer (EVA), or ethylene-methacrylic acid copolymer (SGP). The second glass layer 140 serves as the inner layer of the glass assembly, providing additional physical protection and support while maintaining the overall transparency of the structure. A second frequency selection region 151 is provided on the second metal layer 150, which can selectively reflect or transmit electromagnetic waves of a specific frequency band. It can also integrate any of the following functions, including but not limited to low-emissivity (Low-E) functions, heating functions, and dimming functions. Since the frequency selection region can exhibit high transmittance or high reflectance characteristics within a specific frequency band, by providing a frequency selection region in the metal layer, the metal layer can transmit electromagnetic wave signals of the corresponding frequency band, thereby reducing the shielding effect of the metal layer on electromagnetic wave signals and improving the transmission and reception effects of electromagnetic waves.

[0034] The first glass layer 110 and the second glass layer 140 can be single-layer or multi-layer composite structures (such as tempered glass or laminated glass), which can be configured according to specific usage requirements. The first metal layer 120 and the second metal layer 150 can also be single-layer or multi-layer composite structures. When the metal layer is a single-layer structure, it can be a single metal, such as silver, aluminum, or copper. When the metal layer is a multi-layer composite structure, it can be a composite structure with multiple metals and intermediate layers, which has lower emissivity and better thermal insulation performance. The first frequency selection region 121 can completely cover the first metal layer 120 or be a part of the first metal layer 120. The second frequency selection region 151 can completely cover the second metal layer 150 or be a part of the second metal layer 150. The first frequency selection region 121 and the second frequency selection region 151 allow at least part of electromagnetic waves of the same frequency band to pass through. Therefore, the glass assembly can transmit electromagnetic wave signals of the corresponding frequency band, thereby reducing the shielding effect of the two metal layers on electromagnetic wave signals and improving the transmission and reception of electromagnetic waves.

[0035] In some embodiments, the first frequency selection region 121 is configured as a low-pass frequency selection region, and the second frequency selection region 151 is configured as a high-pass frequency selection region. In other embodiments, the first frequency selection region 121 is configured as a high-pass frequency selection region, and the second frequency selection region 151 is configured as a low-pass frequency selection region. The low-pass frequency selection region allows electromagnetic waves with frequencies lower than the first resonant frequency to pass through, while reflecting or absorbing electromagnetic waves with frequencies higher than the first resonant frequency. The high-pass frequency selection region allows electromagnetic waves with frequencies higher than the second resonant frequency to pass through, while reflecting or absorbing electromagnetic waves with frequencies lower than the second resonant frequency. In this application, the first resonant frequency is set to be higher than the second resonant frequency, meaning the first resonant frequency of the low-pass frequency selection region is higher than the second resonant frequency of the high-pass frequency selection region. Therefore, the glass assembly can transmit electromagnetic waves in the frequency band from the first resonant frequency to the second resonant frequency. Compared to a single-layer bandpass frequency selection surface, the dual-layer structure of this application can have a larger bandwidth. Furthermore, when both the first metal layer 120 and the second metal layer 150 are heat-insulating layers, the dual-layer heat-insulating design can further improve the heat insulation effect of the glass assembly.

[0036] In one embodiment, such as Figure 2 As shown, the low-pass frequency selective region includes multiple metal units 160 separated by gaps, arranged periodically. The periodic arrangement includes, but is not limited to, rectangular arrays, ring arrays, or fan-shaped arrays. Specifically, the low-pass frequency selective region achieves its low-pass characteristics based on the capacitive effect of the multiple metal units 160. When an electromagnetic wave is incident, electrons in the metal units 160 reciprocate under the influence of the electric field. The gaps between the metal units 160 are equivalent to capacitors, and the metal units 160 are equivalent to inductors (the inductance value is extremely small and usually negligible). The transmission characteristics of the capacitive circuit exhibit low-pass characteristics, meaning that low-frequency signals can be transmitted while high-frequency signals are suppressed. In some embodiments, the shape of the metal units 160 is one of rectangles, circles, triangles, or crosses. The shape of the metal units 160 significantly affects the electromagnetic performance of the frequency selective region, such as resonant frequency, bandwidth, polarization sensitivity, and wave absorption characteristics, and can be selected according to specific application requirements.

[0037] In one embodiment, such as Figure 3As shown, the high-pass frequency selective region includes multiple aperture units 170 spaced apart by intervals, arranged periodically. The periodic arrangement includes, but is not limited to, rectangular arrays, ring arrays, or fan-shaped arrays. Specifically, the high-pass frequency selective region achieves its high-pass characteristics based on the inductive effect of the wire grid (the metal constituting the intervals) formed by the multiple aperture units 170. When an electromagnetic wave is incident, electrons in the wire grid reciprocate under the influence of the electric field. The wire grid is equivalent to an inductor, and the aperture unit 170 is equivalent to a capacitor (the capacitance value is extremely small and usually negligible). The transmission characteristics of the inductive circuit exhibit high-pass characteristics, meaning that high-frequency signals can be transmitted while low-frequency signals are suppressed. In some embodiments, the aperture unit 170 is rectangular, circular, triangular, or cross-shaped. The shape of the aperture unit 170 significantly affects the electromagnetic performance of the frequency selective region, such as resonant frequency, bandwidth, polarization sensitivity, and wave absorption characteristics, and can be selected according to specific application requirements.

[0038] In one embodiment, the first resonant frequency of the low-pass frequency selection region is 5 GHz, and the second resonant frequency of the high-pass frequency selection region is 0.5 GHz. With this combination, the glass assembly can pass signals in the 0.5 GHz to 5 GHz frequency band, thus forming a bandpass glass assembly. The bandwidth of the glass assembly of this application is far greater than the bandwidth of a single-layer bandpass frequency selection surface.

[0039] In one embodiment, such as Figure 4 As shown, the side length of the circumscribed rectangle of the metal unit 160 is between 1mm and 2mm. When the metal unit 160 is a rectangle or square, the side length of the circumscribed rectangle is any side length of the metal unit 160. When the metal unit 160 is a circle, irregular shape, or other non-rectangular shape, the circumscribed rectangle is the smallest circumscribed rectangle of the outer edge of the metal unit 160. The gap between adjacent metal units 160 is between 0.1mm and 0.2mm. In some embodiments, the side length of the circumscribed rectangle of the metal unit 160 is 1.6mm, and the gap between adjacent metal units 160 is 0.2mm. In this embodiment, the low-pass frequency selection region is set as a plurality of periodically arranged metal units 160. By setting their specific size and arrangement and selecting a suitable glass layer material, the first resonant frequency of the low-pass frequency selection region can be 5GHz, and it can effectively block electromagnetic waves greater than 5GHz.

[0040] In one embodiment, such as Figure 5As shown, the side length of the circumscribed rectangle of the aperture unit 170 is between 25mm and 40mm, and the interval between adjacent aperture units 170 is between 2mm and 6mm. In some embodiments, the side length of the circumscribed rectangle of the aperture unit 170 is 32mm, and the interval between adjacent aperture units 170 is 4mm. In this embodiment, the high-pass frequency selection region is set as a plurality of periodically arranged aperture units 170. By setting their specific size and arrangement and selecting a suitable glass layer material, the second resonant frequency of the high-pass frequency selection region can be 0.5GHz, and it can effectively block electromagnetic waves below 0.5GHz.

[0041] In one embodiment, such as Figure 6 As shown, the first frequency selection region 121 includes a plurality of first units 123 separated by a first gap 122, and the plurality of first units 123 are arranged periodically; the second frequency selection region 151 includes a plurality of second units 153 separated by a second gap 152, and the plurality of second units 153 are arranged periodically; the first gap 122 and the second gap 152 at least partially overlap along the stacking direction. The first frequency selection region 121 and the second frequency selection region 151 can allow electromagnetic waves of the exact same frequency band or at least partially the same frequency band to pass through.

[0042] Specifically, in this embodiment, the first frequency selection region 121 is composed of a plurality of periodically arranged first units 123, which are separated by a first gap 122. The second frequency selection region 151 is composed of a plurality of periodically arranged second units 153, which are separated by a second gap 152. Both the first unit 123 and the second unit 153 are solid metal patches, and both the first gap 122 and the second gap 152 are gaps formed after removing the metal layer. The first unit 123 and the second unit 153 can be polygonal, circular, or elliptical in shape. The shapes of the first unit 123 and the second unit 153 may be the same or different, and their arrangement may also be the same or different. When the structural shapes of the first unit 123 and the second unit 153 are the same, the passband bandwidth and angular stability can be improved; when the first unit 123 and the second unit 153 are different, they can have different transmission characteristics. In some embodiments, circular structural units can improve polarization stability, and square structural units can have higher processing precision.

[0043] The first gap 122 and the second gap 152 at least partially overlap along the stacking direction of the glass assembly. For example, Figure 6In this embodiment, the first unit 123 and the second unit 153 are set as rectangles of the same shape and size, and their arrangement corresponds one-to-one along the stacking direction. In this case, the first gap 122 and the second gap 152 completely overlap along the stacking direction. When the shapes and sizes of the first unit 123 and the second unit 153 are different, or their arrangement does not correspond along the stacking direction, the first gap 122 and the second gap 152 partially overlap along the stacking direction, and the first frequency selection region 121 and the second frequency selection region 151 are misaligned. This can improve the transmittance of electromagnetic waves of specific frequency bands transmitted from different directions. It is understood that in the combined structure formed by the first frequency selection region 121 and the second frequency selection region 151 in this embodiment, electromagnetic waves of at least a certain frequency band can be transmitted, thereby reducing the shielding effect of the metal layer on electromagnetic wave signals and improving the transmission and reception effect of electromagnetic waves by the glass assembly.

[0044] In one embodiment, such as Figure 7 As shown, a plurality of first units 123 are arranged at intervals along a first direction Y to form a first column unit 124, and a plurality of first column units 124 are arranged at intervals along a second direction X. The first direction Y and the second direction X are perpendicular, and adjacent first column units 124 are aligned along the second direction X. In some other embodiments, such as Figure 8 As shown, adjacent first column units 124 can also be offset along the second direction X.

[0045] In one embodiment, such as Figure 9 As shown, multiple second units 153 are arranged at intervals along the first direction Y to form a second column unit 154, and multiple second column units 154 are arranged at intervals along the second direction X, with adjacent second column units 154 aligned along the second direction X. In some other embodiments, such as Figure 10 As shown, adjacent second column units 154 can also be offset along the second direction X.

[0046] In one embodiment, such as Figure 11 As shown, when two adjacent first column units 124 are offset along the second direction X, the centers of the three first units 123 in the two adjacent first column units 124 that form an adjacent triangular arrangement are connected sequentially to form an equilateral triangle, thereby improving the angular stability of the electromagnetic wave frequency selection of the multilayer metal layer. Specifically, in this embodiment, the centers of the three first units 123 in the adjacent first column units 124 that form an adjacent triangular arrangement due to the offset arrangement are connected sequentially to form an equilateral triangle. In some embodiments, the first unit 123 can be configured as follows: Figure 11 The square shown. In some other embodiments, the first unit 123 may also be a circle, a triangle, or other regular polygon.

[0047] In one embodiment, when two adjacent second column units 154 are offset along the second direction X, the centers of the three second units 153 forming an adjacent triangular arrangement in the two adjacent second column units 154 are connected sequentially to form an equilateral triangle. Specifically, in this embodiment, the centers of the three second units 153 forming an adjacent triangular arrangement due to the offset arrangement in two adjacent second column units 154 are connected sequentially to form an equilateral triangle. In some embodiments, the second unit 153 can be set as a square. In some other embodiments, the second unit 153 can also be set as a circle, triangle, or other regular polygon.

[0048] In one embodiment, such as Figure 12 As shown, the glass assembly also includes an ink layer 180, and a second metal layer 150 disposed between the second glass layer 140 and the ink layer 180. Specifically, the size of the ink layer 180 can match that of the second metal layer 150, or cover a portion of the second metal layer 150. The ink layer 180 reduces direct solar heat by absorbing or scattering visible light (e.g., black ink has an absorption rate of >85% for 550nm visible light), further improving the heat insulation effect of the glass assembly. The ink layer 180 can be set to a single color, gradient, or patterned design to meet the user's personalized needs.

[0049] In one embodiment, such as Figure 13 As shown, the glass assembly includes a visible area and a black edge area, with the black edge area surrounding the visible area. An ink layer 180 is disposed in the black edge area. Specifically, the black edge area is the edge of the glass assembly. In this embodiment, the ink layer 180 is only disposed in the black edge area of ​​the glass assembly to further shield the black edge area. By disposing of the ink layer 180 in the black edge area, the adhesive area during installation and use of the glass assembly can be completely covered, preventing the adhesive from aging, cracking, or peeling due to ultraviolet radiation. In some embodiments, when the ink layer 180 is mixed with inorganic fillers (such as alumina), it can enhance the mechanical strength of the glass edge. The ink layer 180 can also cover sensor areas (such as rain sensors, cameras, etc.) on the edge of the glass assembly, maintaining a clean appearance.

[0050] In one embodiment, when the first metal layer 120 and / or the second metal layer 150 are thermal insulation functional layers of a multi-layer composite structure, the first metal layer 120 and / or the second metal layer 150 are one of a single-silver structure, a double-silver structure, or a triple-silver structure. Specifically, the single-silver structure has only one metal material layer, the double-silver structure has two metal material layers, and the triple-silver structure has three metal material layers. The metal layers can be silver-based films or metal oxide films. All metal material layers form a multi-layer composite structure by combining a dielectric layer (such as aluminum oxide, magnesium oxide, niobium oxide, titanium oxide, tin oxide, zinc oxide, bismuth oxide, indium oxide, indium tin oxide, etc.) and a barrier layer (such as a metal or metal alloy). The more metal material layers, the stronger the thermal insulation and heat preservation performance. It is understood that when forming the frequency selective region, the gaps between the metal units 160, the pore units 170, the first gap 122, and the second gap 152 in the frequency selective region will completely penetrate the entire metal layer structure.

[0051] In one embodiment, this application also proposes a vehicle, which includes the glass assembly described in the above embodiments. The glass assembly is at least one of a sunroof, windshield, side window, and corner window. The vehicle may include land vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or recreational equipment, etc. For example, the vehicle may be a vehicle, which is a vehicle in a broad sense, including transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of this application do not specifically limit the type of vehicle. Furthermore, the vehicle may be an airplane or a ship, etc.

In this specification, the illustrative descriptions of the above terms do not necessarily refer to the same embodiment or example.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
