Alternatively, in the present embodiment, the first rubber ring 410, the second rubber ring 420 and the third rubber ring 430 are sheet materials having a certain sealing property and adhesion property, for example, any one or a combination of at least two of polyvinyl Ding Quanzhi (PolyVinyl Butyral, PVB), ethylene-vinyl acetate copolymer (EVA) or ionic intermediate film (SGP). Further types of materials for the first, second and third rubber rings 410, 420, 430 are not listed or described in detail herein as would be understood by one of ordinary skill in the art.

In some embodiments, as shown in fig. 8, 9a, 9b, 9c, 9d, the dimming module includes a central laminate including a first adhesive layer 100, a dimming device 300, and a second adhesive layer 200 sequentially laminated, and a peripheral assembly including a first rubber ring 410 and a second rubber ring 420, the first rubber ring 410 being disposed in a circumference of the first adhesive layer 100, the first conductive substrate 301 of the dimming device 300, and the dimming medium layer 303 of the dimming device 300, the second rubber ring 420 being disposed in a circumference of the first adhesive layer 100, the second conductive substrate 302 of the dimming device 300, and the dimming medium layer 303 of the dimming device 300, that is, the peripheral assembly being disposed in a circumference of the central laminate; 14 tenon structures 610 are arranged on the inner edge side of the first rubber ring 410, 14 mortise structures 620 are arranged on the outer edge side of the first adhesive layer 100 and the first conductive substrate 301 of the light modulation device 300, namely 14 tenon structures 610 and 14 mortise structures 620 are arranged on the outer edge side of the central laminated body, and the 14 tenon structures 610 and the 14 mortise structures 620 are in one-to-one correspondence and are matched with each other to form a tenon-and-mortise structure 600; similarly, the mortise and tenon joint structure 600 between the second rubber ring 420 and the central laminated body is a similar structure, and will not be described herein.

It should be noted that, when a certain component of the central laminate, for example, the light modulation device 300, has a multi-layer structure, the outer edge side of the component of the central laminate is provided with the tenon structure 610 or the mortise structure 620, the outer edge sides of all the layers of the component may be provided with the tenon structure 610 or the mortise structure 620 (such as the structures of fig. 2, 3, 5a, and 5 b), or the outer edge sides of part of the layers of the component may be provided with the tenon structure 610 or the mortise structure 620 (such as the structures of fig. 9a and 9 b); in either case, the outer edge side of the center stack is provided with a tenon structure or a mortise structure.

In the present embodiment, as shown in fig. 6 and 8, specifically, fig. 7a is a schematic structural diagram of the first conductive substrate 301 in fig. 6, and fig. 7b is a schematic structural diagram of the second conductive substrate 302 in fig. 6.

As shown in fig. 9c and 9d, in the present embodiment, the dimming device 300 includes a first conductive substrate 301, a dimming dielectric layer 303, and a second conductive substrate 302 stacked in this order, the first conductive substrate 301 includes an electrical connection portion 3041, and the electrical connection portion 3041 extends beyond the dimming dielectric layer 303 and the second conductive substrate 302 to form a step 3042; meanwhile, the second conductive substrate 302 also includes an electrical connection portion 3041, and the electrical connection portion 3041 extends beyond the dimming dielectric layer 303 and the first conductive substrate 301 to form a step 3042.

As shown in fig. 9a and 9b, in the present embodiment, the tenon structure 610 of the second rubber ring 420 is located at the step 3042 of the light modulation device 300, and the tenon structure 610 of the first rubber ring 410 is located at the step 3042 of the light modulation device 300.

It will be appreciated that in fig. 9a of the present embodiment, the first adhesive layer 100, the first conductive substrate 301 of the light modulation device 300, and the outer edge side of the light modulation dielectric layer 303 of the light modulation device 300 together form a mortise structure 620, wherein the step formed by the outer edge sides of the first conductive substrate 301 and the light modulation dielectric layer 303 is part of the mortise structure 620.

Similarly, in fig. 9b of the present embodiment, the second adhesive layer 200, the second conductive substrate 302 of the dimming device 300, and the outer edge side of the dimming dielectric layer 303 of the dimming device 300 together form a mortise structure 620, wherein the step formed by the outer edge sides of the second conductive substrate 302 and the dimming dielectric layer 303 is part of the mortise structure 620. In other embodiments of the present application, the relationship between the steps and the mortise structures is similar to that in the present embodiment, and will not be described again.

It should be noted that, the step 3042 is not a solid structure, but a specific space region, because the electrical connection portion 3041 extends beyond the dimming dielectric layer 303 and the second conductive substrate 302 (or the first conductive substrate 301), the first conductive substrate 301, the dimming dielectric layer 303, and the second conductive substrate 302 form a dislocation on a plane parallel to the dimming device 300, so as to form the step 3042. Compared with the method shown in fig. 1 and 4, the tenon structure 610 of the rubber ring 400 is arranged on the side surface of the whole light modulation device 300, so that the appearance of the whole light modulation device 300 is irregular, and the light modulation device 300 needs to be electrically connected with an external power supply, so that when wiring is carried out on the light modulation device 300, bus bars are discontinuous, the complexity of the process is increased, and a plurality of extraction electrodes are required to be arranged to realize the electrical communication among the bus bars, a conductive layer and an EC power supply; or the bus bar avoids the position of the mortise and tenon joint structure 600, but at this time, the shape of the bus bar is irregular, which causes an increase in process difficulty and material cost caused by bending of the bus bar. In this embodiment, since the tenon structure 610 of the rubber ring 400 is disposed at the step of the light modulation device 300, the appearance of the whole light modulation device 300 is still more regular while the tenon-and-mortise structure 600 is formed, as shown in fig. 6, thereby reducing the difficulty in the structural design of the electrical connection between the subsequent light modulation device 300 and the external power supply and improving the production efficiency.

Meanwhile, when the first adhesive layer 100 and the rubber ring 400 are made of different materials (for example, the first adhesive layer 100 is PVB and the rubber ring 400 is SGP), the compatibility of the two materials is not good even after heating and pressurizing, at this time, if the tenon structure 610 of the rubber ring 400 is arranged on the side surface of the whole light modulation device 300 as shown in fig. 1 and 4, the connection stability of the whole light modulation module, especially the connection between the rubber ring 400 and the middle laminated body is still not tight; however, in this embodiment, since the tenon structure 610 of the rubber ring 400 is disposed at the step of the light modulation device 300, after subsequent heating and pressurization, the tenon structure 610 of the rubber ring 400 and the electrical connection portion 3041 of the light modulation device 300 are connected with each other, so that the connection between the rubber ring 400 and the intermediate laminated body is enhanced, and the positions of each rubber ring 400 and the intermediate laminated body can be kept relatively fixed in the subsequent transportation process, so that the convenience of transportation and the structural stability of the whole light modulation module in the transportation process are improved; in the subsequent lamination process, the technician is not required to adjust the positions of the rubber ring 400 and the middle lamination body, so that the production efficiency of the final product is improved.

It will be appreciated that although in this embodiment, the electrical connection portion of the first conductive substrate forms a step beyond the dimming dielectric layer and the second conductive substrate, and at the same time, the electrical connection portion of the second conductive substrate forms a step beyond the dimming dielectric layer and the first conductive substrate; in other cases, however, only the electrical connection portion of the first conductive substrate may be stepped beyond the dimming dielectric layer and the second conductive substrate, or the electrical connection portion of the second conductive substrate may be stepped beyond the dimming dielectric layer and the first conductive substrate. For example, only the electrical connection portion of the first conductive substrate is stepped beyond the dimming dielectric layer and the second conductive substrate, at which time the second conductive substrate may be connected to the external power source by other means, such as punching holes on the second conductive substrate, and etching the second conductive layer to expose the second conductive layer. At this time, the tenon structure of the rubber ring is only positioned at the electric connection part of the first conductive substrate on the dimming device and exceeds the step formed by the dimming medium layer and the second conductive substrate. That is, the structure of the light modulation device can be adaptively designed according to the actual situation by those skilled in the art.

Optionally, in this embodiment, the first conductive substrate 301 and the second conductive substrate 302 are structures with certain conductivity and supporting function, which is usually a combination of a conductive layer and a substrate layer, for example, the conductive layer may be made of materials such as indium-tin oxide (ITO), zinc-aluminum oxide (aluminum zinc oxide, AZO), fluorine doped tin oxide (fluorine doped tin oxide, FTO), silver nanowires, graphene, carbon nanotubes, metal grids, or silver nanoparticles; the substrate layer may be PET (Polyester Film), cyclic olefin copolymer, cellulose triacetate, or the like. Further structure/material types for the first conductive substrate 301 and the second conductive substrate 302 are not listed and described in detail herein, as will be understood by those skilled in the art.

Further, as shown in fig. 9a and 9b, a gap is formed between the tenon structure 610 of the rubber ring 400 and the dimming medium layer 303, so that undesirable stress generated by direct contact between the rubber ring 400 and the dimming medium layer 303 during assembly is avoided, and the first conductive substrate 301 and the second conductive substrate 302 of the dimming device 300 are separated from each other, so that the device is demolded (normal color change cannot be realized in the demolded portion, and even damage of surrounding undeployed portions is accelerated).

In some embodiments, as shown in fig. 9e, in comparison to the structures of fig. 9b and 9d, the dimming module further includes a bus bar 305, the bus bar 305 is disposed at the step 3042 and is connected to the surface of the electrical connection portion 3041 near the dimming medium layer 303, and the tenon structure 610 at the step 3042 of the dimming device 300 is in contact with the surface of the bus bar 305 away from the electrical connection portion.

The bus bar 305 is used to connect the first conductive substrate 301 (or the second conductive substrate 302) and the external power source, so that the voltage, current, etc. of the external power source can be conducted to the whole first conductive substrate 301 (or the second conductive substrate 302) through the bus bar 305, thereby controlling the transmittance of the dimming medium layer 303 to be changed.

It should be noted that, in the present embodiment, the bus bars 305 are all disposed at the step 3042, but those skilled in the art can appreciate that, since the bus bars 305 are used to connect the first conductive substrate 301 (or the second conductive substrate 302) and the external power source, the voltage, the current, etc. of the external power source can be conducted to the whole first conductive substrate 301 (or the second conductive substrate 302) through the bus bars 305, so as to control the transmittance of the dimming medium layer 303 to change, the bus bars 305 only need to at least partially cover the electrical connection portion 3041, i.e. at least partially disposed at the step 3042. For example, the bus bar 305 may be partially disposed at the step 3042, and another portion, such as the protective paste 306 of fig. 9f, is disposed on a side of the second conductive substrate 302 of the light modulation device 300 away from the light modulation dielectric layer 303; the bus bar 305 may be partially disposed at the step 3042, and the other portion is disposed at a side of the first conductive substrate 301 of the light modulation device 300 away from the light modulation medium layer 303, and the like.

Alternatively, in this embodiment, the bus bar 305 may be made of a material with conductivity, which is well known to those skilled in the art, for example, any one or a combination of at least two materials of conductive silver paste, conductive copper paste, conductive carbon paste, nano silver conductive ink, copper foil, copper wire, or conductive adhesive film. Further material types for the bus bar 305 are not listed or described in detail herein, as will be understood by those skilled in the art.

In some embodiments, as shown in fig. 9f, compared to the structure of fig. 9b and 9d, the dimming module further includes a bus bar 305 and a protective glue 306, the bus bar 305 is at least partially disposed at the step 3042 and is connected to a surface of the electrical connection portion 3041 near the dimming dielectric layer 303, a portion of the protective glue 306 is disposed at the step 3042 and is connected to a surface of the bus bar 305 away from the electrical connection portion 3041, and the tenon structure 610 at the step 3042 of the dimming device 300 and the surface of the protective glue 306 away from the electrical connection portion 3041 are in contact.

Similarly, the protective paste 306 may be disposed entirely at the step 3042 or may be partially disposed at the step 3042, as with the bus bar 305.

The protective paste 306 is used to protect the bus bar 305 from corrosion to affect the conductive performance, and when a part of the protective paste 306 is disposed at the step 3042 and a part of the protective paste 306 is disposed on a side of the second conductive substrate 302 of the dimming device 300 away from the dimming dielectric layer 303, the protective paste 306 can also enhance the connection between the first conductive substrate 301 and the second conductive substrate 302 to prevent the conductive substrate of the dimming device 300 from being separated to cause the device to be detached.

Meanwhile, when the first adhesive layer 100 and the rubber ring 400 are made of different materials (for example, the first adhesive layer 100 is PVB and the rubber ring 400 is SGP), the compatibility of the two is not good even after heating and pressurizing, at this time, if the tenon structure 610 of the rubber ring 400 is arranged at the step of the light modulation device 300 as shown in fig. 9a and 9b, although the tenon structure 610 of the rubber ring 400 and the electrical connection part 3041 of the light modulation device 300 are connected with each other after subsequent heating and pressurizing, so that the connection between the rubber ring 400 and the intermediate laminate is enhanced, the electrical connection part 3041 of the rubber ring 400 and the light modulation device 300 is directly connected, and a certain hidden danger exists, for example, accurate control is required, so that the rubber ring 400 is ensured not to damage the electrical connection part 3041 in the heating and pressurizing melting process; in this embodiment, the protection glue 306 is disposed between the electrical connection portion 3041 and the tenon structure 610 of the rubber ring 400, so that the above problem can be avoided, and meanwhile, the protection glue can also select a material with stronger binding force with the rubber ring 400 (such as a material with similar properties, or a material with similar properties, which is not described herein), so as to enhance the binding force between the rubber ring 400 and the light modulation device 300, so that the positions of each rubber ring 400 and the middle laminated body can be kept relatively fixed in the subsequent transportation process, thereby improving the convenience of transportation and the structural stability of the whole light modulation module in the transportation process; in the subsequent lamination process, the technician is not required to adjust the positions of the rubber ring 400 and the middle lamination body, so that the production efficiency of the final product is improved.

In some embodiments, the tenon structure 610 of the rubber ring 400 and the dimmer device 300 are glued to each other. For example, the tenon structure 610 of the rubber ring 400 may be glued to the first conductive substrate 301 (or the second conductive substrate 302) at the step 3042, or glued to the bus bar 305 at the step 3042, or glued to the protective glue 306 at the step 3042, and in other possible cases, the application is not repeated, and can be reasonably adjusted according to practical situations.

At this time, since the tenon structure 610 of the rubber ring 400 and the light modulation device 300 are mutually glued together, the connection between the rubber ring 400 and the light modulation device 300 can be further enhanced, namely, the connection between the rubber ring 400 and the middle laminated body is enhanced, so that the positions of the rubber rings 400 and the middle laminated body can be kept relatively fixed in the subsequent transportation process, thereby improving the convenience of transportation and the structural stability of the whole light modulation module in the transportation process; in the subsequent lamination process, the position of the rubber ring and the intermediate lamination body is not required to be adjusted by a technician, so that the production efficiency of the final product is improved.

In some embodiments, as shown in fig. 10a and 10b, the dimming device is two layers, including the first dimming device 310 and the second dimming device 320, and a third adhesive layer 1000 is disposed between adjacent dimming devices, compared to the structure of fig. 9 a.

Alternatively, in the present embodiment, the first and second dimming devices 310 and 320 may be electrochromic dimming devices, liquid crystal dimming devices, photochromic dimming devices, or the like. Preferably, when the first dimming device 310 and the second dimming device 320 are electrically driven dimming devices, they include a dimming medium and a conductive substrate, and the conductive substrate may be one layer, two layers or multiple layers, and when it is a two-layer conductive substrate structure, the first conductive substrate and the second conductive substrate are disposed at both sides of the dimming medium, respectively. Optionally, the dimming medium is one or a combination of more than two of a liquid dimming medium, a solid dimming medium or a sol dimming medium. Preferably, the dimming medium is a solid state dimming medium. More preferably, the dimming medium is a solid electrochromic stack layer comprising an ion storage layer, an electrolyte layer and an electrochromic layer arranged in sequence.

The third adhesive layer 1000 may be a material having a certain adhesive capability, such as any one or a combination of at least two of polyvinyl alcohol Ding Quanzhi (PolyVinyl Butyral, PVB), ethylene-vinyl acetate copolymer (Ethylene-vinyl Acetate Copolymer, EVA), OCA (Optically Clear Adhesive) optical adhesive, SCA optical adhesive, ionic interlayer (SGP), liquid optical adhesive LOCA (Liquid Optical Clear Adhesive), or acryl.

It should be noted that, when the dimming module at least includes two layers of dimming devices, the third adhesive layer 1000 is not necessarily configured, but the upper surface of one layer of dimming device may be directly contacted with the lower surface of the other layer of dimming device, but at this time, there is a problem that the two layers of dimming devices easily slide relatively, so the third adhesive layer 1000 is often disposed between adjacent dimming devices to enhance the connection stability of the adjacent dimming devices.

In some embodiments, as shown in fig. 11a and 11b, compared to the structure of fig. 10a and 10b, the projection of the third adhesive layer 1000 and the conductive substrate adjacent to each other above and below the third adhesive layer is completely overlapped on the first adhesive layer 100.

It is easy to see that in fig. 10a and 10b, gaps exist between the step of two dimming devices of the dimming module and adjacent bonding layers and rubber rings, that is, the bonding layers and the rubber rings cannot perfectly fill the space at the step, at this time, voids are easily present in subsequent final products to affect the attractiveness and performance of the devices, meanwhile, after subsequent lamination processes, for example, after vacuum lamination, the gaps at the step cannot be fully filled by the bonding layers and the rubber rings to form vacuum holes, and the vacuum holes and the ambient atmospheric pressure outside the rubber rings form pressure differences, so that the rubber rings are easily perforated, thereby causing the sealing failure of the dimming module.

In this embodiment, the projection of the third adhesive layer 1000 and the conductive substrate adjacent to the third adhesive layer from top to bottom on the first adhesive layer 100 are completely overlapped, so that the adhesive layer and the rubber ring can perfectly fill the space at the step of the two dimming devices, thereby avoiding the above problem, prolonging the service life of the devices, and simultaneously, the three layers of rubber rings have the tenon structure design, so that the connection stability of the whole dimming module is enhanced.

In some embodiments, as shown in fig. 12, compared to the structure of fig. 11a, the dimming module further includes a first protective layer 800, a second protective layer 900 and a shielding layer 1100, specifically, a side of the first adhesive layer 100 away from the second adhesive layer 200 is provided with the first protective layer 800, a side of the second adhesive layer 200 away from the first adhesive layer 100 is provided with the second protective layer 900, the shielding layer 1100 is disposed on an upper surface of the first protective layer 800, and in a direction parallel to the first adhesive layer 100, a width N1 of the shielding layer 1100 is not less than a width N2 of the rubber ring 400.

The protective layer can play a role in protecting and supporting the bonding layer and the light modulation device, so that damage in the subsequent transportation and use processes is avoided; the shielding layer can shield the area incapable of dimming so as to enhance the visual experience of a user and improve the aesthetic property of the product, therefore, the width N1 of the shielding layer is not smaller than the width N2 of the rubber ring, and further, when the width N1 of the shielding layer is smaller than the width N2 of the rubber ring, the fault tolerance in assembly is larger. It should be noted that the protective layer may exist separately from the shielding layer.

In addition, in this embodiment, the shielding layer is disposed on the upper surface of the first protection layer 800, and it will be understood by those skilled in the art that the shielding layer may be disposed on the lower surface of the first protection layer 800, or disposed on the upper surface of the second protection layer 900, or disposed on the lower surface of the second protection layer 900, or disposed on two or more of the four surfaces at the same time, where other possible, the present application is not repeated, and may be reasonably adjusted according to practical situations.

Alternatively, in the present embodiment, the first protective layer 800 and the second protective layer 900 may be materials having a certain water-oxygen blocking property, such as a water-oxygen blocking film, glass, etc., so that the entire dimming module may be directly mounted to an end product, such as an automobile sunroof, a side window, a building curtain wall, etc.; the first protective layer 800 and the second protective layer 900 may also be flexible transparent resin materials, which only protect the internal structure, and before the subsequent lamination process, the protective layers may be removed to facilitate subsequent processing, specifically, at this time, the materials of the first protective layer 800 and the second protective layer 900 may be PET (Polyethylene terephthalate abbreviated as PET or PEIT, commonly called polyester resin, polycondensate of terephthalic acid and ethylene glycol), PMMA (polymethyl methacrylate (poly (methyl methacrylate)), abbreviated as PMMA), also called acryl, acryl (english Acrylic) or organic glass, PC (Polycarbonate), and PI (Polyimide), etc. Further material types for the first protective layer 800 and the second protective layer 900 are not listed and described in detail herein, as will be understood by those skilled in the art.

Alternatively, in the present embodiment, the shielding layer 1100 may be a film layer or a frame structure having a shielding effect, and when the shielding layer 1100 is a film layer, it may be, for example, an ink layer, a metal plating layer, or the like; when the shielding layer 1100 is a frame structure, it may be as shown in fig. 13. The specific design may be selected based on the actual situation, and further material types or structural designs of the shielding layer 1100 are not listed or described in detail herein, as will be understood by those skilled in the art.

The embodiment of the application also provides a terminal product, which comprises the dimming module, wherein the terminal product comprises any one of a rearview mirror, a curtain wall, an automobile skylight, an automobile side window, an automobile windshield, a shell of an electronic product, glasses, a vehicle and a display panel.

Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the application, and the scope of the application should be assessed accordingly to that of the appended claims.
