[0034] 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.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] In a specific embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a stacked assembly 10 is provided. The stacked assembly 10 includes a first light-transmitting film 102 and a second light-transmitting film 104 stacked in sequence. The stacked assembly 10 also includes a frame 106, a plurality of rotatable dimming films 108, a plurality of spaced shafts 110 and a control mechanism 112.

[0037] The frame 106 is sandwiched between the first light-transmitting film 102 and the second light-transmitting film 104.

[0038] The transmittance of the dimming film 108 is adjustable.

[0039] Multiple axes 110 are fixedly connected to multiple dimming films 108 in a one-to-one correspondence. The axes 110 are connected to the frame 106 and can move along the frame 106 to adjust the distance between two adjacent dimming films 108.

[0040] The control mechanism 112 is used to drive the dimming diaphragm 108 to move, so as to adjust the projected area of ​​the dimming diaphragm 108 on the second light-transmitting diaphragm 104. The movement of the dimming diaphragm 108 includes, but is not limited to, whole-piece rotation, fan-shaped opening and closing, and scroll-shaped opening and closing, depending on the material and shape of the dimming diaphragm 108. Any movement that can change the projected area on the second light-transmitting diaphragm 104 is within the scope of protection of this application.

[0041] Multiple dimming films 108 are sandwiched between the sheet-like first light-transmitting film 102 and second light-transmitting film 104, preventing direct contact with the external environment. In contrast, the slats of traditional venetian blinds are in direct contact with the external environment, causing dust to accumulate easily and resulting in high cleaning costs. Furthermore, traditional venetian blinds have built-in mechanical guide rails, which are also prone to dust accumulation when in direct contact with the external environment, leading to rail jamming. In this application, the dimming films 108 are sandwiched between the first light-transmitting film 102 and second light-transmitting film 104. Taking the arrangement of multiple dimming films 108 as an example of venetian blind distribution, the sheet-like first light-transmitting film 102 and second light-transmitting film 104 can isolate the dimming films 108 from the external environment, thus preventing dust accumulation or stains from splashing onto the dimming films 108 and ensuring their cleanliness. If dust or stains from the external environment contaminate the stacked component 10, the stacked component 10 can be cleaned by wiping the side of the first light-transmitting film 102 that is close to the external environment and the side of the second light-transmitting film 104 that is close to the external environment. This cleaning method is simple and convenient to operate.

[0042] Of course, the arrangement of the multiple dimming films 108 can also be other arrangements. Specifically, the arrangement of the multiple dimming films 108 satisfies the following requirements: when the surface of the multiple dimming films 108 is perpendicular to the surface of the first light-transmitting film 102, ambient light in the external environment can pass through the stacked assembly 10 and be projected into the internal environment (the user's environment, for example, inside a vehicle or indoors); when the surface of the multiple dimming films 108 is parallel to the surface of the first light-transmitting film 102, at least a portion of the ambient light in the external environment cannot pass through the stacked assembly 10 and be projected into the internal environment.

[0043] Axis 110 can move along frame 106. Taking the stacked component 10 as the window glass as an example, if axis 110 is parallel to the horizontal plane, then axis 110 can move up and down along the edge of frame 106 in the vertical direction; if axis 110 is perpendicular to the horizontal plane, then axis 110 can move left and right along the edge of frame 106 in the horizontal direction.

[0044] When the interval between two adjacent axes 110 increases and the state of the dimming films 108 remains unchanged, the projected area of ​​each dimming film 108 on the second light-transmitting film 104 remains constant. When the distance between the projected areas of two adjacent dimming films 108 on the second light-transmitting film 104 widens to the point where there is a gap between the projections of the two adjacent dimming films 108, the amount of light projected from the external environment to the internal environment increases as the gap between the projections widens. The state of the dimming films 108 may include rotation angle and open / closed status.

[0045] When the interval between two adjacent axes 110 decreases and the state of the dimming films 108 remains unchanged, the projected area of ​​each dimming film 108 on the second transparent film 104 remains constant. Before the distance between the projected areas of two adjacent dimming films 108 on the second transparent film 104 narrows to the point where the projections of the two adjacent dimming films 108 overlap, the amount of light projected from the external environment to the internal environment decreases as the gap between the projections narrows. Therefore, by adjusting the distance between each axis 110, the dimming position of the stacked assembly 10 acting on the internal environment can be adjusted, thereby achieving the adjustment of the brightness of the internal ambient light. When the distance between each dimming film 108 is at its maximum, the light transmitted through the stacked assembly 10 is the most; when the distance between each dimming film 108 is at its minimum, the light transmitted through the stacked assembly 10 is the least. The distance between any two adjacent axes 110 can be adjusted individually.

[0046] The control mechanism 112 can directly drive the shaft 110 to rotate, so that the shaft 110 drives the dimming diaphragm 108 to rotate. In this case, the shaft 110 mainly serves to drive the dimming diaphragm 108 to rotate. The control mechanism 112 can also drive other rotating components connected to the dimming diaphragm 108 to rotate. In this case, the shaft 110 mainly serves to support the dimming diaphragm 108.

[0047] Taking the rotation of the dimming diaphragm 108 as an example, when the rotation angle of the dimming diaphragm 108 changes, the projected area of ​​the dimming diaphragm 108 on the second light-transmitting film 104 also changes. When this laminated assembly 10 is used as window glass, the effective dimming area of ​​the laminated assembly 10 acting on the internal environment can be adjusted by changing the rotation angle of the dimming diaphragm 108. Specifically, when the projected area of ​​the dimming diaphragm 108 on the second light-transmitting film 104 increases, the effective dimming area for the internal environment also increases; when the projected area of ​​the dimming diaphragm 108 on the second light-transmitting film 104 decreases, the effective dimming area for the internal environment also decreases. The rotation angle of each dimming diaphragm 108 can be adjusted individually.

[0048] Traditional PDLC dimming glass features a single-piece design. When used for shading, this design limits its shading capabilities, making partial shading impossible and the shading position unadjustable to user needs. In contrast, the stacked component 10 of this application allows for precise adjustment of the effective dimming area within the internal environment by adjusting the rotation angle of the dimming films 108. Furthermore, adjusting the distance between the axes 110 allows for adjustment of the effective dimming position within the internal environment. Additionally, the transmittance of each dimming film 108 is adjustable, enabling multi-dimensional dimming and providing high flexibility.

[0049] For example, the fogging effect of the dimming film 108 varies under different transmittance levels. Compared to traditional PDLC dimming glass, which only has two states—transmittance and full fogging—this laminated component 10 can be in a low fogging state. When the laminated component 10, including the low fogging state, is used as window glass, it can soften the light projected from the external environment to the internal environment, allowing the internal environment to obtain soft, low-glare light, thereby reducing the lighting energy consumption of the internal environment. This laminated component 10 can also be in a full fogging state to completely block the projection of external ambient light, creating a low-brightness atmosphere.

[0050] In one specific embodiment, the dimming film 108 is a non-flexible dimming film that rotates around an axis; or, the dimming film 108 is a flexible dimming film that deforms during movement. Rotation of the non-flexible dimming film around an axis includes whole-piece rotation; flexible deformation includes, but is not limited to, fan-like opening and closing deformation and roll-like opening and closing deformation.

[0051] When the dimming diaphragm 108 is a non-flexible dimming diaphragm, it cannot be bent. In this case, the dimming diaphragm 108 can be rotated by adjusting the orientation of its blades (e.g., the angle relative to the first light-transmitting diaphragm 102). The maximum rotation angle range of the dimming diaphragm 108 is 360 degrees, which covers both the cases where the dimming diaphragm 108 is perpendicular to the first light-transmitting diaphragm 102 and the cases where the dimming diaphragm 108 is parallel to the first light-transmitting diaphragm 102.

[0052] Taking the angle between the dimming diaphragm 108 and the surface of the first light-transmitting diaphragm 102 as a reference angle of 0°, the rotation angle range of the dimming diaphragm 108 is 0° to 180°. When this stacked component 10 is mounted on a building as window glass, the dimming diaphragm 108 can rotate downwards, with the dimming diaphragm 108 positioned relatively close to the interior environment side, facing the interior environment. At this time, each dimming diaphragm 108 forms a certain angle with the vertical direction, allowing users on the interior environment side to clearly observe the exterior environment, while people on the exterior environment side cannot obtain a view of the interior environment, ensuring user privacy. If the dimming diaphragm 108 rotates upwards, tilting upwards and facing the exterior environment, people in the interior environment can clearly see stains on the dimming diaphragm 108. If stains are found on the dimming diaphragm 108, it can be determined that the first light-transmitting diaphragm 102 or the second light-transmitting diaphragm 104 has been damaged and requires repair. Furthermore, when the rotation angle of the dimming diaphragm 108 is less than 180°, ambient light can be projected into the interior environment through the gaps between the dimming diaphragms 108, thereby illuminating the interior environment on the user's side. When the rotation angle of the dimming diaphragm 108 is equal to 180°, the ambient light is atomized by the stacked components 10, thereby reducing the intensity of light projected into the interior environment, or even blocking the light projected into the interior environment, thus achieving a shading effect. Further, the rotation angle range of the dimming diaphragm 108 is 0° to 360° to balance the ability to observe the blades while maintaining privacy and security within the interior environment.

[0053] Furthermore, the rotation angle range of the dimming film 108 is 0° to 90°. Specifically, when the rotation angle of the dimming film 108 is 0° (perpendicular to the plane where the first light-transmitting film 102 is located), it can maximize the introduction of sunlight from the external environment, thereby increasing the internal ambient temperature in winter; when the dimming film 108 rotates to 60°, it can reduce the heat radiation from direct sunlight, thereby lowering the internal ambient temperature in summer; when the dimming film 108 rotates to 30°, the internal environment can obtain soft diffused light, suitable for business scenarios such as conference rooms; when the dimming film 108 rotates to 90°, by adjusting the transmittance of the dimming film 108, it can maximize the blocking of external ambient light, achieving the best sunshade effect.

[0054] When the distance between all dimming films 108 is at its maximum and the rotation angle of the dimming films 108 is 0°, the stacked assembly 10 exhibits high light transmittance. When the distance between all dimming films 108 is at its minimum and the rotation angle of the dimming films 108 is 90°, and the dimming films 108 have low transmittance, the stacked assembly 10 exhibits high fogging. Specifically, when the distance between all dimming films 108 is at its minimum and the rotation angle of the dimming films 108 is 90°, the distance between the dimming films 108 can be zero, which can solve the edge light leakage problem of traditional PDLCs.

[0055] When the dimming film 108 is a flexible dimming film, it can be rolled up like a roller or folded like a fan. Taking the roller-type dimming film 108 as an example, in this case, the dimming film 108 can be wound around the shaft 110 as the winding center. Using the laminated assembly 10 as the window glass as an example, when shading is not required, the dimming film 108 can be wound around the shaft 110 to minimize the effective dimming area; when shading is required, at least some of the blades of the dimming film 108 wound around the shaft 110 can be unfolded to increase the projected area of ​​the dimming film 108 on the second light-transmitting film 104. Therefore, by adjusting the unfolded area of ​​the dimming film 108, the effective dimming area of ​​the internal environment can be adjusted. When the dimming film 108 is fully unfolded and has low transmittance, external ambient light can be blocked to the maximum extent, achieving the best shading effect. Furthermore, the roll-up dimming film 108 requires little space to move, which is beneficial for the thin-film design of stacked components.

[0056] In one specific embodiment, shaft 110 is a magnetic coupling, the driving shaft of the magnetic coupling is connected to the control mechanism 112, and the driven shaft of the magnetic coupling is connected to the dimming diaphragm 108.

[0057] The control mechanism 112 is used to drive the drive shaft of the magnetic coupling to drive the driven shaft to move, so that the driven shaft drives the dimming diaphragm 108 to rotate.

[0058] The driving shaft of the magnetic coupling generates a magnetic field under the drive of the control mechanism 112. The driven shaft rotates synchronously with the driving shaft under the electromagnetic force corresponding to this magnetic field, thereby driving the dimming diaphragm 108 to rotate and adjusting the projected area of ​​the dimming diaphragm 108 on the second light-transmitting diaphragm 104. The stacked assembly 10 equipped with the magnetic coupling can achieve contactless magnetic coupling transmission between the inner and outer cavities. Therefore, the interlayer space formed by the first light-transmitting diaphragm 102 and the second light-transmitting diaphragm 104 can be completely sealed, thereby preventing oil or water stains from the external environment from contaminating the dimming diaphragm 108, ensuring that the dimming diaphragm 108 can remain clean, and reducing cleaning and maintenance costs.

[0059] As can be seen, the stacked component 10 does not have mechanical guide rails, which can avoid fatigue damage of mechanical guide rails, thereby extending the service life of the stacked component 10 and enabling the dimming diaphragm 108 to rotate more than 100,000 times.

[0060] In one specific embodiment, when each dimming diaphragm 108 is an electrically controlled dimming diaphragm, it further includes a dimming control module.

[0061] The dimming control module is connected to each electronically controlled dimming film and is used to adjust the transmittance of the electronically controlled dimming film.

[0062] The dimming control module can adjust the transmittance of the electronically controlled dimming film, allowing it to produce different fogging effects. When the laminated component 10 serves as the window glass, if the user requires high-brightness light, the transmittance of the electronically controlled dimming film can be increased to allow more ambient light to pass through and be projected into the interior environment. If the user requires low-brightness light, the transmittance of the electronically controlled dimming film can be decreased to enhance the fogging effect, blocking more ambient light and reducing the intensity of light projected into the interior environment. If the user requires a dark interior environment, the transmittance of the electronically controlled dimming film can be adjusted to the lowest possible level to maximize the isolation of ambient light and create a dark environment.

[0063] Compared to mechanical architecture, the dimming control module of electronic architecture has higher adjustment precision. When the transmittance adjustment range of the electronic dimming film includes 10% to 90% transmittance, it can achieve stepless adjustment of 10% to 90% transmittance.

[0064] Furthermore, the transmittance of each electronically controlled dimming film can be adjusted individually. Taking the laminated component 10 as an example of window glass in an office building, the dimming film 108 projected onto the desk is divided into a first area film, and the dimming film 108 projected onto the interior floor is divided into a second area film. In this case, the transmittance of the first area film can be less than that of the second area film. At this time, the shading effect on the desk is better than that on the interior floor, which can reduce the glare for office workers when reading documents on the desk, while also enhancing the brightness of the interior office environment and reducing the energy consumption of interior lighting.

[0065] In one embodiment, the dimming control module is connected to a terminal wirelessly. This terminal can be a smartphone, smart tablet, smart bracelet, or similar device.

[0066] Users can send control commands to the dimming control module via the terminal, so that the dimming control module can control the transmittance of the electronically controlled dimming film accordingly.

[0067] In one embodiment, the dimming control module supports light-sensing control.

[0068] A dimming control module that supports light-sensing control can adjust the transmittance of the electronically controlled dimming film according to the intensity of light. For example, taking the laminated component 10 as a window glass in a building, the dimming control module can display different transmittance depending on different weather conditions. Specifically, on sunny days, when the ambient light intensity is high, the dimming control module reduces the transmittance of the electronically controlled dimming module based on the high light intensity, reducing the intensity of light projected from the external environment to the internal environment, thus providing softer lighting to the internal environment. On cloudy days, when the ambient light intensity is low, the dimming control module increases the transmittance of the electronically controlled dimming module based on the low light intensity, enhancing the intensity of light projected from the external environment to the internal environment, thus providing bright lighting to the internal environment.

[0069] In one specific embodiment, the electronically controlled dimming film is a polymer-dispersed liquid crystal film, a suspended particle device film, an electrochromic film, or a liquid crystal film.

[0070] Polymer-dispersed liquid crystal films are low-cost and have a fast response speed, enabling millisecond-level switching between full light transmission and full fogging. For example, when an electrically controlled dimming film uses a laminated assembly 10 of polymer-dispersed liquid crystal films as window glass, it is suitable for buildings requiring high-frequency adjustment of the internal environment's shading effect.

[0071] The suspended particle device diaphragm has a high UV blocking rate, good heat insulation effect, and strong impact resistance. For example, when the electrically controlled dimming diaphragm uses the laminated component 10 of the suspended particle device diaphragm as window glass, it is suitable for automotive applications, serving as vehicle window glass to provide UV protection for occupants and maintain a comfortable interior temperature. Furthermore, in the event of a vehicle collision, the strong impact resistance of the suspended particle device diaphragm protects the occupants, ensuring good safety.

[0072] Electrochromic films have low energy consumption and maintain their current light transmission state even when power is off, making them suitable for scenarios requiring a consistent shading effect over a long period. For example, when an electrochromic film laminated component 10 is used as window glass, it can be used as window glass in building curtain walls and aircraft windows to provide users with a relatively stable lighting environment despite varying ambient light conditions. Furthermore, given the large area of ​​building curtain walls and the limited energy resources on aircraft, low-energy electrochromic films can reduce energy consumption and save costs.

[0073] Furthermore, when the electrochromic film laminated assembly 10 is used as the window glass, the dimming control module is powered off when the electrochromic film is in a fully frosted state, thereby reducing the power supply burden and energy loss. When it is necessary to adjust the light transmittance of the electrochromic film, the dimming control module can be manually powered on to adjust the light transmittance of the electrochromic film.

[0074] When transparent, the optical performance of liquid crystal films is close to that of clear glass, with no color distortion, making them suitable for scenarios requiring high-precision displays. For example, when an electrically controlled dimming film uses a stacked component 10 of liquid crystal films as window glass, it can be used as automotive glass, allowing occupants to clearly observe road conditions through the transparent stacked component 10, thus ensuring driving safety.

[0075] In a specific embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, when the dimming diaphragm 108 is a non-flexible dimming diaphragm, multiple dimming diaphragms 108 form a louver structure. The control mechanism 112 also includes a traction device 1122 and an electronic control module 1124.

[0076] The traction device 1122 is used to pass through each dimming diaphragm 108 in sequence.

[0077] The electronic control module 1124 is connected to the traction device 1122. The electronic control module 1124 is used to drive the traction device 1122 to drive multiple dimming diaphragms 108 to rotate synchronously.

[0078] like Figure 4 As shown, at least one wire hole can be provided on the dimming diaphragm 108. The traction device 1122 passes through these wire holes to connect multiple dimming diaphragms 108 in series. Under the drive of the electronic control module 1124, the traction device 1122 can simultaneously drive the dimming diaphragms 108 to rotate by the same angle, so as to uniformly adjust the angle of each dimming diaphragm 108 and reduce the complexity of operation.

[0079] In one embodiment, such as Figure 2 and Figure 4 As shown, two wire holes can be provided on the dimming diaphragm 108 to correspond to the two traction devices 1122, thereby increasing the stability of the dimming diaphragm 108. Furthermore, if any traction device 1122 breaks, the other traction device 1122 can still drive each dimming diaphragm 108 to rotate, thereby increasing the reliability of the stacked assembly 10.

[0080] In one embodiment, such as Figure 5As shown, two symmetrical wire-passing holes are provided with axis 110 as the center, so that the traction device 1122 passes through these two wire-passing holes in sequence. The symmetrical traction design can increase the stability of the dimming diaphragm 108 during the traction process, reduce the swaying of the dimming diaphragm 108 during rotation, and improve the user's comfort.

[0081] In one embodiment, such as Figure 2 As shown, with at least two wire holes provided on each dimming module, the control mechanism 112 also includes a bracket 1126.

[0082] Each traction device 1122 is connected to a point on the bracket 1126. The number of traction devices 1122 is the same as the number of wire holes on a dimming diaphragm 108.

[0083] Taking the example of each dimming module having two wire holes, the bracket 1126 can adjust the force direction of the traction device 1122. When the first wire holes of each dimming module are on the same line and the second wire holes are on the same line, the bracket 1126 can support the traction device 1122 to continue to be set along the distribution direction of the first wire holes and the distribution direction of the second wire holes, thereby reducing the stress on the traction device 1122, reducing the risk of breakage of the traction device 1122, and thus extending the service life of the stacked component 10.

[0084] In one embodiment, the traction device 1122 can be a traction wire or a transparent hinge. The traction wire is less expensive, enabling uniform traction adjustment of the dimming diaphragm 108 at a lower cost. The transparent hinge offers higher reliability and durability, supporting long-term, frequent uniform traction adjustment.

[0085] In one embodiment, the bracket 1126 is a transparent bracket. When the laminated assembly 10 serves as window glass, the transparent bracket can reduce obstruction of the view.

[0086] In one embodiment, the control mechanism 112 can be a mechanical control mechanism such as a knob. Through this mechanical control mechanism, the rotation angle of each dimming diaphragm 108 and the distance between adjacent dimming diaphragms 108 can be directly adjusted without the use of power, making it suitable for scenarios with limited power resources.

[0087] In one embodiment, the control mechanism 112 can be a solar energy automatic sensing control mechanism. This mechanism allows for direct adjustment of the rotation angle of each dimming film 108 and the distance between adjacent dimming films 108 without the use of a power source, making it suitable for scenarios with abundant solar energy. Specifically, as sunlight intensity gradually increases, the rotation angle of each dimming film 108 tends to be the angle when the dimming film 108 is parallel to the surface of the first light-transmitting film 102, and / or, the distance between adjacent dimming films 108 tends to be 0, thus achieving a better shading effect. As sunlight intensity gradually decreases, the rotation angle of each dimming film 108 tends to be the angle when the dimming film 108 is perpendicular to the surface of the first light-transmitting film 102, and / or, the distance between adjacent dimming films 108 tends to be the maximum distance, thus obtaining more ambient light.

[0088] In one specific embodiment, the above-described stacked component 10 further includes: an edge sealing strip.

[0089] The sealing strip is used to seal the interlayer space formed by the first light-transmitting film 102 and the second light-transmitting film 104.

[0090] The sealing strip can maintain the airtightness of the interlayer space formed by the first light-transmitting film 102 and the second light-transmitting film 104 and the weather resistance of the glass.

[0091] In one embodiment, the laminated assembly 10 may include a sealing strip disposed between the first light-transmitting film 102 and the second light-transmitting film 104, and surrounding the outer edge of the frame 106. In this case, the sealing strip can seal the interlayer space formed by the first light-transmitting film 102 and the second light-transmitting film 104, reducing the risk of dust or stains from the external environment contaminating the light-transmitting films.

[0092] In one embodiment, the laminated assembly 10 may include two sealing strips, namely a first sealing strip and a second sealing strip. The first sealing strip is disposed between the first light-transmitting film 102 and the frame 106, and the second sealing strip is disposed between the second light-transmitting film 104 and the frame 106. In this case, the sealing strips can seal the interlayer space formed by the first light-transmitting film 102, the second light-transmitting film 104, and the frame 106, reducing the risk of dust or stains from the external environment contaminating the light-transmitting film. Furthermore, when the laminated assembly 10 includes the first and second sealing strips, the interlayer space formed by the first light-transmitting film 102, the second light-transmitting film 104, and the frame 106 is larger than the interlayer space formed by the first light-transmitting film 102 and the second light-transmitting film 104. In this case, the area of ​​each dimming film 108 can be appropriately increased to reduce the number of dimming films 108 and reduce the complexity of the assembly steps of the laminated assembly 10.

[0093] In one specific embodiment, the pins of the dimming control module and the electronically controlled dimming diaphragm are packaged using laser sealing.

[0094] Through a metallization process, a metallized layer can be formed on the stacked component 10. Laser sealing allows for rapid fusion of the metal pins to the metallized layer, creating a leak-free, sealed structure. The wires connecting the dimming control module and the electronically controlled dimming diaphragm can be connected to the metal pins via brazing, spot welding, or other methods, thus achieving circuit connection. This laser sealing process effectively prevents moisture from the external environment from penetrating into the interlayer space formed by the first and second transparent films 102, thereby ensuring the airtightness of the interlayer space.

[0095] In one specific embodiment, the above-described stacked component 10 further includes: a first protective layer and / or a second protective layer.

[0096] The first protective layer is disposed on at least one side of the first light-transmitting film 102 and / or the second light-transmitting film 104; wherein the first protective layer is an ultraviolet protection film.

[0097] The second protective layer is disposed on at least one side of the first light-transmitting film 102 and / or the second light-transmitting film 104; wherein the second protective layer is an infrared reflective coating.

[0098] Specifically, the first protective layer and / or the second protective layer can be disposed on the side of the first light-transmitting film 102 that is close to the external environment and / or on the side of the first light-transmitting film 102 that is away from the external environment; correspondingly, the first protective layer and / or the second protective layer can be disposed on the side of the second light-transmitting film 104 that is close to the external environment and / or on the side of the second light-transmitting film 104 that is away from the external environment.

[0099] When the first protective layer and / or the second protective layer are disposed on the side of the first light-transmitting film 102 and / or the second light-transmitting film 104 away from the external environment, the risk of water vapor corrosion or damage to the first protective layer and / or the second protective layer by sharp objects in the external environment can be reduced, thereby extending the service life of the first protective layer and / or the second protective layer.

[0100] When the first protective layer and / or the second protective layer are disposed on the side of the first light-transmitting film 102 and / or the second light-transmitting film 104 that is close to the external environment, they can directly reflect ultraviolet and / or infrared rays, thereby reducing the aging rate of the second light-transmitting film 104, the frame 106, each dimming film 108, and the axis 110, and / or intercepting infrared heat radiation. For example, taking the laminated assembly 10 as a window glass, if the first light-transmitting film 102 is disposed close to the external environment and the second light-transmitting film 104 is disposed close to the internal environment, the first protective layer and / or the second protective layer can be disposed on the side of the first light-transmitting film 102 that is close to the external environment to reduce the aging rate of the second light-transmitting film 104, the frame 106, each dimming film 108, and the axis 110, and / or intercept infrared heat radiation conducted from the external environment side to the internal environment side through the laminated assembly 10, maintaining the temperature stability of the internal environment side.

[0101] In one specific embodiment, the above-mentioned stacked component 10 further includes an inert gas, which fills the interlayer space formed by the first light-transmitting film 102 and the second light-transmitting film 104.

[0102] Inert gases have low thermal conductivity and low convection. When inert gases are filled into the interlayer space, they can suppress heat conduction and achieve thermal insulation. For example, taking the laminated component 10 as window glass, when inert gases are filled into the interlayer space, they can suppress heat conduction between the external and internal environments. In winter, the heat from the heating system inside the interior is difficult to transfer to the external environment, thus achieving insulation of the internal environment in winter. In summer, the high temperature heat from the external environment is difficult to transfer to the internal environment, thus achieving thermal insulation of the internal environment in summer. Therefore, filling with inert gases can also reduce the power consumption of internal cooling or heating equipment, achieving energy saving.

[0103] For example, the inert gas can be argon. Argon does not react with materials such as glass, metal coatings, and sealants, and is suitable for both frigid environments of -40°C and high-temperature environments of 85°C. Therefore, the argon-filled laminated assembly 10 has a wide range of applications and can adapt to extreme environments with varying temperatures.

[0104] In one specific embodiment, both the first light-transmitting film 102 and the second light-transmitting film 104 are glass plates.

[0105] The glass panel has excellent optical properties, good light transmission, and high clarity. Therefore, the laminated component 10 can be used as automotive glass to provide drivers with a high-definition view, thereby ensuring driving safety.

[0106] In one embodiment, both the first light-transmitting film 102 and the second light-transmitting film 104 are tempered glass plates.

[0107] Compared to ordinary glass, tempered glass is stronger and suitable for scenarios where there may be an impact risk. For example, the laminated component 10 can be used as automotive glass to improve its impact resistance.

[0108] In one embodiment, the first light-transmitting film 102 and / or the second light-transmitting film 104 are hollow structure glass.

[0109] Insulating glass has good thermal insulation performance. Therefore, the first light-transmitting film 102 and / or the second light-transmitting film 104 are suitable for the stacked components 10 of insulating glass, which are often exposed to direct sunlight or for vehicles traveling in open areas.

[0110] In one embodiment, the first transparent film 102 and / or the second transparent film 104 are vacuum hollow structure glass.

[0111] Vacuum-insulated hollow glass can provide both sound insulation and heat insulation. Therefore, the first light-transmitting film 102 and / or the second light-transmitting film 104 are suitable for the stacked components 10 of vacuum-insulated hollow glass in scenarios that require sound insulation and heat insulation.
