It is also to be understood that the term "or" as used herein encompasses both the conjunctive and disjunctive meanings of "or," unless the context clearly dictates otherwise.

[0036] In one embodiment, as shown in FIG. 1, a laminated assembly 10 is provided, comprising a transparent substrate 110 and a functional film layer 120. Figure 1

[0037] The functional film layer 120 is disposed on one side of the transparent substrate 110, and the functional film layer 120 has at least one communication area 122.

[0038] The communication area 122 on the functional film layer 120 has a plurality of hollow areas 1222 arranged periodically to support the passage of radio frequency signals in a predetermined frequency band.

[0039] ​The hollowed-out areas 1222 arranged periodically form a frequency selective surface structure. Specifically, the hollowed-out areas 1222 of different shapes and sizes, and the hollowed-out areas 1222 arranged in different periodic lengths, can support different resonant frequencies. Therefore, when the resonant frequencies supported by the shapes, sizes, and periodic lengths of the arrangement of the hollowed-out areas 1222 are in a preset frequency band, the communication window formed by the communication area 122 can support the radio frequency signals in the preset frequency band to pass through, thereby realizing communication between the devices on both sides of the laminated assembly 10.

[0040] The transparent substrate 110 refers to a material with good light transmittance and certain mechanical strength. For example, the transparent substrate 110 can be glass, acrylic, polycarbonate, PVC (Polyvinyl chloride) transparent plastic plate, ceramic, etc. The transparent substrate 110 can include one or more dielectric layers. The dielectric layer can include a dielectric layer (insulating layer, for example, glass plate, etc.). The functional film layer 120 can include a light-adjusting layer, a temperature-adjusting layer, a low-emissivity film layer (LOW-E), a silver-coated layer, and other conductive functional layers, which can be determined according to the functions of the laminated assembly 10.

[0041] Specifically, the laminated assembly 10 described above, by arranging at least one communication area 122 on the functional film layer 120 and forming hollowed-out areas 1222 arranged periodically in the communication area 122 to support the radio frequency signals in a preset frequency band to pass through, is conducive to realizing high-quality communication between the devices on both sides of the laminated assembly 10. That is, the laminated assembly 10 provided in the embodiments of the present application can not only realize the functions of the functional film layer 120, but also take into account the communication quality between the devices on both sides.

[0042] For example, in an example, the laminated assembly 10 is applied to a vehicle. The functional film layer 120 is a film layer with one or more functions of heat preservation, heat insulation, sound insulation, or light adjustment. When a user is in the vehicle, the laminated assembly 10 can provide a comfortable environment with low ultraviolet rays and low noise through heat preservation, heat insulation, sound insulation, or light adjustment. On this basis, the user device / vehicle-mounted device can communicate with the device outside the vehicle through the communication area 122 on the laminated assembly 10 in a preset frequency band, thereby maintaining good communication effect. When the user is outside the vehicle, the user's mobile phone and other user devices can also send instructions, such as adjusting the temperature in the vehicle, pre-cooling, and pre-heating, to the vehicle-mounted device. The instructions are based on radio frequency signals that pass through the laminated assembly 10 through the communication area 122, and the loss on the propagation path is small, which can ensure that the radio frequency signals carrying the instructions are accurately sent to the vehicle-mounted device, thereby improving the response reliability of the vehicle machine.

[0043] Similarly, the laminated assembly 10 can also be applied to the field of building and other fields to support communication between the devices on both sides of the laminated assembly 10, which will not be described here.

[0044] In one embodiment, the communication area 122 is multiple, and the multiple communication areas 122 on the functional film layer 120 correspond to support multiple preset frequency bands with the same or different frequency ranges.

[0045] Wherein, when part or all of the multiple communication areas 122 support communication of the same preset frequency band, electromagnetic waves radiated from different directions to the laminated assembly 10 can be transmitted, thereby supporting multi-directional communication of a single preset frequency band and improving communication quality.

[0046] When part or all of the multiple communication areas 122 respectively support different preset frequency bands, multi-band communication can be achieved, the communication needs of users in various scenarios can be met, and communication performance can be improved.

[0047] In one embodiment, the shape of the hollow area 1222 is one of a cross shape, a ring shape, and a circular shape.

[0048] Wherein, Figure 2a The shape of the hollow area 1222 shown is a cross shape, and details can be seen from the enlarged view of the cross shape Figure 2b The cross shape has a gap, and by adjusting the gap width of the cross shape, the radio frequency signal of the preset frequency band can be transmitted from one side of the hollow area 1222 to the other side of the hollow area 1222 through the gap of the cross shape, while the signal of the non-preset frequency band is reflected to prevent the signal of the non-preset frequency band from being transmitted through the hollow area 1222. Therefore, by setting the cross-shaped hollow area 1222 on the functional film layer 120, precise selection of radio frequency signals can be achieved.

[0049] Figure 3a The shape of the hollow area 1222 shown is a ring shape, and details can be seen from the enlarged view of the ring shape Figure 3b The ring-shaped hollow area 1222 has strong wideband application capability, can also reduce signal loss, and at the same time improve transmission efficiency. Therefore, by setting the ring-shaped hollow area 1222 on the functional film layer 120, the wideband communication demand can be met, and the communication quality in the wideband range can be guaranteed.

[0050] Figure 4a The shape of the hollow area 1222 shown is a circular shape, and details can be seen from the enlarged view of the circular shape Figure 4b The circular hollow area 1222 has a good symmetry structure, thereby being able to provide uniform signal coverage and provide uniform radiation field in each radiation direction, which is conducive to realizing omnidirectional communication. Therefore, by setting the circular hollow area 1222 on the functional film layer 120, the 360-degree communication demand can be met.

[0051] In an embodiment, the plurality of hollowed regions 1222 of the communication region 122 collectively form a preset identification pattern. The preset identification pattern can be set according to the object to which the laminated assembly 10 is actually applied. For example, the preset identification pattern on the laminated assembly 10 can be a trademark symbol of the manufacturer of the laminated assembly 10, such as a "FY" character, and the like. For another example, when the laminated assembly 10 is applied to a vehicle, the preset identification pattern can be the shape of the logo of the vehicle, thereby improving the identification of the vehicle. Correspondingly, when the laminated assembly 10 is applied to the field of architecture, the preset identification pattern can also be the representative shape of the building. In addition, the preset identification pattern can also be a polygon, a circle, an ellipse, and the like, which will not be described herein.

[0052] In an embodiment, the communication region 122 is disposed close to the edge of the functional film layer 120.

[0053] The disposition of the communication region 122 close to the edge of the functional film layer 120 can reduce the presence of the communication region 122 while ensuring the communication quality, and reduce the negative impact of the hollowed region 1222 on the function implementation of the user when using the functional film layer 120. For example, when the functional film layer 120 is a display film, the disposition of the communication region 122 at the edge of the functional film layer 120 can ensure the display integrity of the main region of the display film. For another example, when the functional film layer 120 is a low-radiation film layer, and the laminated assembly 10 is applied to a vehicle, the ultraviolet rays are blocked when the ambient light transmits through the low-radiation film layer. By disposing the hollowed region 1222 at the edge of the functional film layer 120, most of the ambient light transmitted through the hollowed region 1222 does not irradiate the position where the passengers are located, thereby ensuring the low-radiation environment in the vehicle and providing a comfortable internal environment for the user. In addition, when the user observes an object on the other side through the laminated assembly 10, the main visual field is concentrated in the middle region. By disposing the communication region 122 at the edge of the functional film layer 120, the visual effect of the user when observing the object can be ensured.

[0054] For another example, when the functional film layer 120 is a one-way privacy film, by disposing the hollowed region 1222 at the edge of the functional film layer 120, the user privacy can be better protected compared to the disposition of the hollowed region 1222 in the middle region of the laminated assembly 10.

[0055] In an embodiment, the transparent substrate 110 includes at least one glass plate.

[0056] Compared to other transparent substrates 110, the glass has a higher light transmittance, a more stable chemical property, and a wider application range. For example, in the field of vehicles, the glass can be used as a vehicle window. When the laminated assembly 10 whose transparent substrate 110 is glass is applied to a vehicle and used as a vehicle window, the normal communication between the devices in the vehicle and the devices outside the vehicle can be ensured while the ultraviolet rays, infrared rays, or sound outside the vehicle is isolated.

[0057] Take the case that the transparent substrate 110 includes a layer of glass plate, and the preset frequency band is the Bluetooth communication frequency band (the frequency band is: 2.4GHz-2.5GHz) for example to test:

[0058] As shown in Figure 5 , there is a piece of coated glass 20 with an area of 380mm*380mm, the antenna A on one side of the coated glass 20 is 200mm away from the antenna B on the other side, and the distance between the antenna A and the coated glass 20 is equal to the distance between the antenna B and the coated glass 20. The antenna A sends a Bluetooth signal to the antenna B, and the Bluetooth signal transmits through the coated glass 20 to the antenna B to complete the transmission and reception of the Bluetooth signal. According to the Bluetooth signal strength emitted by the antenna A and the Bluetooth signal strength received by the antenna B, the antenna isolation degree on both sides of the coated glass 20 is shown in the curve of Figure 6 .

[0059] As shown in Figure 7 , the coated glass 20 described above is replaced by a laminated assembly 10 with a communication area 122, the functional film layer 120 of the laminated assembly 10 is the same as the film layer of the coated glass 20 in Figure 5 , and the transparent substrate 110 of the laminated assembly 10 is a glass plate with the same glass material as the coated glass 20. Under the same conditions, the antenna isolation degree is detected, and the detection results corresponding to the curve in Figure 6 are obtained.

[0060] The higher the absolute value of the value of the antenna isolation degree, the higher the isolation degree between the antennas, and referring to Figure 6 , compared with the coated glass 20 in the prior art, the absolute value of the antenna isolation degree on both sides of the laminated assembly 10 is reduced from 35dB to 15dB, so under the same conditions, compared with the coated glass 20 in the prior art, the laminated assembly 10 can improve the transmission effect between the antennas on both sides, thereby improving the communication quality.

[0061] For example, the laminated assembly 10 can be installed on a vehicle body to support Bluetooth communication between in-vehicle devices and out-of-vehicle devices. Specifically, a Bluetooth key is equipped with a Bluetooth antenna, and when a user is outside the vehicle, the user can remotely control the components supporting Bluetooth communication in the vehicle through the Bluetooth key. The laminated assembly 10 supports Bluetooth signal transmission, which can ensure the remote connection, positioning and use effect of the Bluetooth key, and improve the user experience.

[0062] In one embodiment, the manufacturing steps of the laminated assembly 10 can include the following steps:

[0063] providing a transparent substrate 110;

[0064] coating a film on one side of the transparent substrate 110 to form a functional film layer 120;

[0065] The functional film layer 120 is subjected to film removing operation in a preset pattern, and the preset pattern is a plurality of hollow areas 1222 arranged periodically.

[0066] The transparent substrate 110 with the functional film layer 120 is subjected to film sintering and solidification to obtain the laminated assembly 10.

[0067] In one embodiment, the manufacturing steps of the laminated assembly 10 can also include the following steps:

[0068] The transparent substrate 110 is provided.

[0069] The communication areas 122 on the transparent substrate 110 are covered by the filling cover plates arranged periodically.

[0070] The side of the transparent substrate 110 where the cover plates are arranged is subjected to film plating to form the functional film layer 120, and the functional film layer 120 has the hollow areas 1222 arranged opposite to the filling cover plates.

[0071] The transparent substrate 110 with the functional film layer 120 is subjected to film sintering and solidification to obtain the laminated assembly 10.

[0072] Therefore, the hollow areas 1222 of the communication areas 122 in the laminated assembly 10 can be obtained after film removing operation after film plating, or can be reserved by the filling cover plates before film plating.

[0073] In one embodiment, the preset frequency band includes one or more of a cellular mobile communication frequency band, a Bluetooth communication frequency band, and a WiFi communication frequency band.

[0074] The current devices basically support one or more of the signals corresponding to the cellular mobile communication frequency band, the Bluetooth signals corresponding to the Bluetooth communication frequency band, and the WiFi signals corresponding to the WiFi communication frequency band, and therefore, the laminated assembly 10 supporting the communication signals can meet the communication in most cases. Of course, the radio frequency signals can also include communication signals other than the above examples.

[0075] The signals corresponding to the cellular mobile communication frequency bands include 2G (Second Generation Mobile Communication Technology), 3G (Third Generation Mobile Communication Technology), 4G (Fourth Generation Mobile Communication Technology), 5G (Fifth Generation Mobile Communication Technology), and 6G (Sixth Generation Mobile Communication Technology). As shown in FIG. 1, the transparent substrate 110 is provided with a functional film layer 120, and the functional film layer 120 is provided with a plurality of hollow regions 1222 arranged periodically. Figure 8 Figure 8 FIG. 2 is a schematic diagram of the transmission of radio frequency signals through the hollow regions 1222.

[0076] In one embodiment, the functional film layer 120 is one layer or multiple layers. When the functional film layer 120 is multiple layers, at least one of the layers of the functional film layer 120 can be provided with the hollow regions 1222 arranged periodically. For example, the laminated assembly 10 is applied to a vehicle, and the functional film layer 120 can include a heat insulation film, a light control film, an anti-fouling film, a display film, a touch film, and a scratch-resistant film. The hollow regions 1222 can be provided on at least one of the heat insulation film, the light control film, the anti-fouling film, the display film, the touch film, or the scratch-resistant film. Specifically, the hollow regions 1222 can be provided only on the heat insulation film, thereby maximizing the light control function of the light control film, the anti-fouling function of the anti-fouling film, the display function of the display film, the touch function of the touch film, and the protection function of the scratch-resistant film. The hollow regions 1222 can also be provided on the heat insulation film and the light control film to improve the communication effect of the radio frequency signals and to prevent external pollutants from penetrating and damaging the heat insulation film, the light control film, and the transparent substrate 110. The hollow regions 1222 can also be provided on the heat insulation film, the light control film, the anti-fouling film, and the scratch-resistant film to maximize the communication effect of the radio frequency signals. Of course, the above examples are only illustrative and do not specifically limit the actual position of the hollow regions 1222.

[0077] In one embodiment, a vehicle is provided, including a vehicle body and the laminated assembly 10 as described above, wherein the laminated assembly 10 is installed on the vehicle body.

[0078] The laminated assembly 10 can be used as the front windshield, the rear windshield, the side window, the corner window, or the sunroof of the vehicle.

[0079] Further, as shown in FIG. 3, the laminated assembly 10 can be used as the front windshield of the vehicle.​Figure 4a and Figure 9 As shown in FIG. 1, when the laminated assembly 10 is installed on a vehicle body, the laminated assembly 10 has a black border area 124 formed at the edge of the laminated assembly 10 and having a certain width.

[0080] The black border area can be coated with a coating containing glass enamel, which can improve the strength and toughness of the laminated assembly 10. Alternatively, the communication area 122 of the functional film layer 120 is arranged in the black border area.

[0081] In one embodiment, the transparent substrate is single-layer or multi-layer, and the functional film layer is arranged on one side of one of the transparent substrates.

[0082] For example, when the laminated assembly 10 includes one transparent substrate 110, the functional film layer 120 is arranged on the side of the transparent substrate 110 close to ambient light.

[0083] The functional film layer 120 can isolate the transparent substrate 110 from external pollutants, reduce the penetration and damage of external pollutants to the transparent substrate 110, and prolong the service life of the laminated assembly 10.

[0084] Of course, in one embodiment, when the laminated assembly 10 includes one transparent substrate 110, the functional film layer 120 is arranged on the side of the transparent substrate 110 away from ambient light, for example, when the functional film layer 120 is a touch film, it is arranged on the side of the transparent substrate 110 away from ambient light, which is convenient for users inside the vehicle to operate when the laminated assembly 10 is installed on a vehicle.

[0085] When the laminated assembly 10 includes a laminated multi-layer transparent substrate 110, the functional film layer 120 can be arranged between two of the transparent substrates 110 or on the side of the multi-layer transparent substrate 110 close to ambient light.

[0086] For example, the laminated assembly 10 can include two laminated transparent substrates 110, and the functional film layer 120 can be arranged between the two transparent substrates 110. The transparent substrates 110 on both sides can protect the functional film layer 120.

[0087] In addition, when the functional film layer 120 is arranged between the two transparent substrates 110, the functional film layer 120 can include a polymer film with adhesion, and when the transparent substrate 110 is broken, the broken fragments on both sides can be adhered to the polymer film in the middle, thereby reducing the splashing of the fragments and reducing the risk of injury to the human body, improving safety protection. The functional film layer 120 can also be arranged on the side of the two transparent substrates 110 close to ambient light, and at this time, the functional film layer can support heat insulation, light adjustment, scratch prevention, etc.

[0088] Of course, with the multi-layer transparent substrate 110, the functional film layer 120 can also be arranged on the side of the multi-layer transparent substrate 110 away from the ambient light. For example, when the functional film layer 120 is a touch film, the arrangement is beneficial for user operation.

[0089] For example, when the functional film layer 120 is a single layer, the functional film layer 120 can be a heat insulation film. Since the heat insulation film can reflect or absorb part of the heat in the external environment, the heat accumulation in the vehicle can be reduced. When the heat insulation film is arranged on the side of the transparent substrate 110 close to the ambient light, it can directly face the sunlight, thereby improving the reflection efficiency and maintaining the temperature comfort of the vehicle environment. The functional film layer 120 can also be a dimming film. Since the dimming film needs to directly receive external light to adjust the light transmittance, the dimming film can be arranged on the side of the transparent substrate 110 close to the ambient light. The functional film layer 120 can also be an anti-fouling film. When the anti-fouling film is arranged on the side of the transparent substrate 110 close to the ambient light, it can isolate the transparent substrate from external pollutants, thereby reducing the penetration and damage of external pollutants to the transparent substrate 110 and prolonging the service life of the laminated assembly 10. The functional film layer 120 can also be a scratch-resistant film. The scratch-resistant film can prevent sharp objects from directly damaging the transparent substrate 110, thereby protecting the transparent substrate 110.

[0090] Of course, the functional film layer 120 can also be multi-layered. For example, the functional film layer 120 can include a heat insulation film, a dimming film, an anti-fouling film, and a scratch-resistant film. The functional film layer 120 can include a first layer, a second layer, a third layer, and a fourth layer arranged in sequence, wherein the first layer is the layer close to the ambient light. The scratch-resistant film can be arranged on the first layer to protect other film layers. The anti-fouling film can be arranged on the second layer to isolate other film layers from external pollutants when the scratch-resistant film is damaged, thereby ensuring that the functions of the dimming film and the heat insulation film are not affected. The dimming film can be arranged on the third layer to directly receive external light as much as possible, thereby improving the response efficiency of dimming. The heat insulation film can be arranged on the fourth layer to ensure the temperature comfort of the vehicle environment. Of course, in addition to the heat insulation film, the dimming film, the anti-fouling film, and the scratch-resistant film arranged in sequence, the functional film layer 120 can also include other functional film layers, which will not be described here.

[0091] In one embodiment, when the laminated assembly 10 is one of a vehicle front windshield, a vehicle rear windshield, a vehicle side window, and a vehicle corner window, the communication area 122 is arranged close to the lower edge of the laminated assembly 10.

[0092] In the case that the laminated assembly 10 is a front windshield of a vehicle, the communication area 122 is arranged close to the lower edge of the laminated assembly 10, which does not block the main visual field of the driver, thereby ensuring the safety of driving. Further, the communication systems, navigation systems and other systems or devices requiring communication of the vehicle are usually arranged at the front of the vehicle, and the mobile phones and other devices requiring communication of the user are usually placed on the center console or the central armrest box of the vehicle. Therefore, the communication area 122 arranged close to the lower edge of the laminated assembly 10 is as close as possible to the systems, devices and equipment requiring communication, thereby shortening the communication distance and improving the communication quality.

[0093] In the case that the laminated assembly 10 is a rear windshield of a vehicle, the communication area 122 arranged close to the lower edge of the laminated assembly 10 can be as close as possible to the reversing monitoring module and the rear blind area monitoring module of the vehicle, thereby improving the communication quality of the reversing monitoring module and the rear blind area monitoring module and ensuring the safety of the vehicle.

[0094] In the case that the laminated assembly 10 is a side window of a vehicle, the communication area 122 arranged close to the lower edge of the laminated assembly 10 can support the normal communication between the devices inside and outside the vehicle when the side window of the vehicle is in the fully raised state.

[0095] In the case that the laminated assembly 10 is a corner window of a vehicle, the communication area 122 arranged close to the lower edge of the laminated assembly 10 does not block the visual field of the driver, thereby ensuring the safety of driving.
