[0040] The embodiment of the present application provides a light adjusting structure, the light adjusting structure comprises a light adjusting piece 100 and a sealing piece 200, the light adjusting piece 100 has a first preset surface 110 and a second preset surface 120, the sealing piece 200 is arranged at an edge area of the light adjusting piece 100 in a bending mode, the sealing piece 200 has a first surface 210 close to the first preset surface 110 and a second surface 220 close to the second preset surface 120, wherein the first surface 210 is attached to the first preset surface 110, the second surface 220 is attached to the second preset surface 120, and the first surface 210 is partially attached to the second surface 220, and an end of the sealing piece 200 away from the light adjusting piece 100 is arranged in a closed mode.

[0041] Referring to Figure 1 As shown in the figure, the first preset surface 110 is an upper surface at an edge of the light adjusting piece 100, the second preset surface 120 is a lower surface at the edge of the light adjusting piece 100, the sealing piece 200 is an integral whole, the sealing piece 200 is in a "U" shape after being bent, the first surface 210 is a surface of the sealing piece 200 facing the first preset surface 110, the second surface 220 is a surface of the sealing piece 200 facing the second preset surface 120, specifically, the first surface 210 is partially connected to the first preset surface 110, the second surface 220 is partially connected to the second preset surface 120, and the remaining part of the first surface 210 and the remaining part of the second surface 220 are outside the light adjusting piece 100, and the remaining part of the first surface 210 is connected to the remaining part of the second surface 220.

[0042] Further, based on the deficiencies of the two-layer glue layer for closing the edge of the light adjusting piece 100 and the single-layer glue layer for closing the edge of the light adjusting piece 100, the single-layer closing mode is still adopted to seal the edge of the light adjusting piece 100, specifically, the remaining part of the first surface 210 and the first preset surface 110 and the remaining part of the second surface 220 and the second preset surface 120 are partially bonded on one side of the light adjusting piece 100, so that the parts of the edge of the light adjusting piece 100, such as wrinkles, warping and wave bending, can be tightly bonded by coating, the overall sealing performance and the aesthetic appearance are improved, the protection of the edge of the light adjusting piece 100 is improved, and the discoloration failure of the light adjusting material in the light adjusting piece 100 is reduced.

[0043] It should be noted that the water vapor may enter from the bonding surface when the upper and lower two layers of glue are used to paste and seal the edge of the light adjusting piece 100, but the single layer sealing mode of the part of the first surface 210 and the second surface 220 is adopted in the present application, and the water vapor cannot enter from the side, so that better waterproofness can be achieved; and compared with the single layer glue which is tightly wrapped and sealed after being bent on the special-shaped side, since the part of the first surface 210 and the part of the second surface 220 are connected and can be extended on the bent and special-shaped side, therefore, the part of the glue which is tightly wrapped on the side will not produce wrinkles, so that the side looks more beautiful, avoiding the obvious gap between the glue and the side of the light adjusting piece 100 when they are pasted, and improving the sealing performance of the glue.

[0044] The light adjusting piece 100 has a third preset surface 130, the third preset surface 130 is connected with the first preset surface 110 and the second preset surface 120, the first surface 210 and the second surface 220 of the sealing piece 200 form an extension 300 at the pasted part, the first surface 210 at the extension 300 is bent to form a first contact surface 310 towards the third preset surface 130, and the second surface 220 at the extension 300 is bent to form a second contact surface 320 towards the third preset surface 130, and the first contact surface 310 and the second contact surface 320 are pasted with the third preset surface 130.

[0045] It can be understood that the third preset surface 130 in the above is the side surface of the light adjusting piece 100, which is transitionally connected with the first preset surface 110 and the second preset surface 120.

[0046] Please continue to refer to Figure 1 As shown, in order to further improve the sealing performance of the light adjusting piece 100 as a whole and prevent water vapor and the like from entering between the sealing piece 200 and the light adjusting piece 100, the remaining part of the sealing piece 200 connected with the first preset surface 110 and the second preset surface 120 protrudes from the side of the first preset surface 110 and the second preset surface 120 to form an extension 300, at this time, the protruding part is the part of the first surface 210 and the second surface 220 which are bonded to each other. In order to further seal the light adjusting piece 100, the part of the extension 300 towards the third preset surface 130 is divided into a first contact surface 310 and a second contact surface 320 by the bonding surface of the first surface 210 and the second surface 220, it can be understood that the first contact surface 310 is part of the first surface 210, and the second contact surface 320 is part of the second surface 220, and the first contact surface 310 and the second contact surface 320 are bonded with the third preset surface 130, so as to realize the sealing of the side of the light adjusting piece 100.

[0047] In one embodiment, the first contact surface 310 and the second contact surface 320 of the extension 300 are bonded with the third preset surface 130 to discharge the gas possibly existing between the side edge of the light adjusting piece 100 and the sealing piece 200, and to some extent, also to block the external moisture and air from entering the bonding surface formed between the sealing piece 200 and the third preset surface 130 of the light adjusting piece 100, to reduce the risk of moisture entering the inside of the light adjusting piece 100, and to improve the service life of the light adjusting piece 100.

[0048] The extension 300 has an extension end, which is the end of the extension away from the light adjusting piece 100, and the distance between the extension end and the peripheral surface of the light adjusting piece 100 is X, which satisfies: 0 < X ≤ 30 mm.

[0049] X is in the range of 0 < X ≤ 30 mm, for example, X can be 0.05 mm, 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 7 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc., which can be set according to the actual situation. Preferably, 0.2 mm ≤ X ≤ 5 mm. More preferably, 0.5 mm ≤ X ≤ 3 mm.

[0050] It can be understood that when X is too small, the first surface 210 and the second surface 220 are easily separated from each other, and cannot form a stable bond, and when X is too large, the proportion of the non-color-changing area of the light adjusting piece 100 is increased, and the proportion of the non-color-changing area here is the ratio of the non-color-changing area of the light adjusting piece 100 to the total area of the light adjusting piece 100, and when the proportion of the non-color-changing area is large, the proportion of the color-changing area that can realize the light adjusting function will be correspondingly reduced.

[0051] The sealing piece 200 includes a glue layer 233 and a bearing layer 232, the glue layer 233 is arranged on the side of the bearing layer 232 close to the light adjusting piece 100, the side of the glue layer 233 facing the first preset surface 110 is the first surface 210, and the side of the glue layer 233 facing the second preset surface 120 is the second surface 220.

[0052] Please refer to Figure 2 When the bearing layer 232 and the glue layer 233 are an integral whole, the bearing layer 232 and the glue layer 233 together form a high-temperature adhesive tape, a waterproof adhesive tape, a high-temperature waterproof adhesive tape, etc., and after the glue layer 233 is bent into a "U" shape, the side of the glue layer 233 facing the first preset surface 110 is the first surface 210, and the side of the glue layer 233 facing the second preset surface 120 is the second surface 220.

[0053] The carrier layer 232 can be made of polyethylene glycol terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymer, or cellulose triacetate, etc.

[0054] The water-oxygen barrier layer 231 is arranged on the side of the carrier layer 232 away from the adhesive layer 233.

[0055] Please continue to refer to Figure 2 As shown, the water-oxygen barrier layer 231 is located at the outermost side, i.e., the water-oxygen barrier layer 231 is located on the side of the carrier layer 232 away from the light-adjusting piece 100 and the adhesive layer 233. The water-oxygen barrier layer 231 can reduce the risk of water vapor entering the light-adjusting piece 100 through the carrier layer 232 and the adhesive layer 233 in the direction perpendicular to the first preset surface 110, the second preset surface 120, and the third preset surface 130, thereby improving the service life of the light-adjusting piece 100.

[0056] The light-adjusting piece 100 comprises a first conductive substrate 140, a light-adjusting medium layer 150, and a second conductive substrate 160 arranged in sequence. The edge portion of the light-adjusting piece 100 is further provided with a first recess 410 and a second recess 420. The first recess 410 penetrates the first conductive substrate 140 and the light-adjusting medium layer 150, so that the first surface 210 is attached to the side of the first conductive substrate 140 close to the light-adjusting medium layer 150. The second recess 420 penetrates the second conductive substrate 160 and the light-adjusting medium layer 150, so that the second surface 220 is attached to the side of the second conductive substrate 160 close to the light-adjusting medium layer 150.

[0057] Please continue to refer to Figure 3 , Figure 4 and Figure 5It should be noted that, when the first surface 210 of the adhesive layer 233 is bonded to the first conductive substrate 140, the first surface 210 cannot completely adhere to the side wall of the first conductive substrate 140 and the light-adjusting medium layer 150, but forms an air passage at the position where the first conductive substrate 140 and the light-adjusting medium layer 150 are bent at the bottom of the first groove 410. Similarly, when the second surface 220 of the adhesive layer 233 is bonded to the second conductive substrate 160, the second surface 220 cannot completely adhere to the side wall of the second groove 420, but forms an air passage at the position where the second conductive substrate 160 and the light-adjusting medium layer 150 are bent at the bottom of the second groove 420. Therefore, if the first surface 210 and the second surface 220 do not cover the edge of the light-adjusting piece 100, the ambient water vapor can easily enter through the air passage, thereby causing the discoloration failure of the light-adjusting medium layer 150. Therefore, when the first groove 410 and the second groove 420 are provided at the edge of the light-adjusting piece 100, the first surface 210 and the second surface 220 of the adhesive layer 233 cover the edge of the light-adjusting piece 100, and the water vapor outside is isolated by the adhesive layer 233 and the carrier layer 232, thereby preventing the water vapor and other adverse factors outside from entering the light-adjusting piece 100 and affecting the service life of the light-adjusting piece 100.

[0058] The extension 300 is formed on the bonded part of the first surface 210 and the second surface 220 of the sealing piece 200, and the surface of the extension 300 is flush with the first conductive substrate 140 or the second conductive substrate 160.

[0059] It should be noted that, in the present embodiment, the height of the extension 300 is the same as the height of the first conductive substrate 140 or the second conductive substrate 160, that is, the upper surface of the extension 300 is flush with the first conductive substrate 140 or the lower surface of the extension 300 is flush with the second conductive substrate 160, thereby improving the stability of the overall structure.

[0060] The light-adjusting piece 100 further comprises a first bus bar 171 and a second bus bar 172. At least part of the first bus bar 171 is arranged on the side of the second conductive substrate 160 close to the light-adjusting medium layer 150 through the first groove 410, and at least part of the second bus bar 172 is arranged on the side of the first conductive substrate 140 close to the light-adjusting medium layer 150 through the second groove 420. The first surface 210 of the sealing piece 200 covers the first bus bar 171, and the second surface 220 of the sealing piece 200 covers the second bus bar 172.

[0061] In some embodiments, as shown in FIG. 6, the first bus bar 171 and the second bus bar 172 are arranged on the side of the first conductive substrate 140 and the second conductive substrate 160 close to the light-adjusting medium layer 150, respectively. Figure 8As shown, one part of the first bus bar 171 is arranged on the side of the second conductive substrate 160 close to the light adjusting medium layer 150 through the first groove 410, and the other part of the first bus bar 171 is arranged on the side of the first conductive substrate 140 away from the light adjusting medium layer 150. One part of the second bus bar 172 is arranged on the side of the first conductive substrate 140 close to the light adjusting medium layer 150 through the second groove 420, and the other part of the second bus bar 172 is arranged on the side of the second conductive substrate 160 away from the light adjusting medium layer 150.

[0062] In some other embodiments, all the first bus bars 171 are arranged on the side of the second conductive substrate 160 close to the light adjusting medium layer 150 through the first groove 410, and all the second bus bars 172 are arranged on the side of the first conductive substrate 140 close to the light adjusting medium layer 150 through the second groove 420.

[0063] The first bus bar 171 and the second bus bar 172 can be made of materials with conductivity known to those skilled in the art, for example, at least one of conductive silver paste, conductive copper paste, conductive carbon paste, nano-silver conductive ink, copper foil, copper wire and conductive adhesive film.

[0064] By arranging the first bus bar 171 and the second bus bar 172, when the external power supply supplies power to the light adjusting piece 100, the current can be quickly conducted to the periphery of the second conductive substrate 160 through the first bus bar 171, and to the periphery of the first conductive substrate 140 through the second bus bar 172, thereby accelerating the color changing speed of the light adjusting piece 100. In addition, the first bus bar 171 is covered by the first surface 210 of the adhesive layer 233, and under the action of the adhesive layer 233 and the carrier layer 232, the first bus bar 171 can be prevented from being corroded by water vapor in the environment, affecting its conductivity and in turn affecting the color changing speed of the light adjusting piece 100. At the same time, to some extent, the position of the first surface 210 of the adhesive layer 233 can also enhance the adhesion between the first bus bar 171 and the second conductive substrate 160, reduce the probability of local electrical conduction failure caused by partial separation of the first bus bar 171 and the second conductive substrate 160, and avoid its influence on the color changing speed of the light adjusting piece 100. Similarly, the second bus bar 172 is covered by the position of the second surface 220 of the adhesive layer 233, which can prevent the second bus bar 172 from being corroded by water vapor in the environment, affecting its conductivity and in turn affecting the color changing speed of the light adjusting piece 100. At the same time, to some extent, the second surface 220 of the adhesive layer 233 can also enhance the adhesion between the second bus bar 172 and the first conductive substrate 140, reduce the probability of local electrical conduction failure caused by partial separation of the second bus bar 172 and the first conductive substrate 140, and avoid its influence on the color changing speed of the light adjusting piece 100.

[0065] Further, as shown in FIG. 6, the first bus bar 171 and the second bus bar 172 can be arranged on the side of the carrier layer 232 close to the light adjusting medium layer 150. Figure 5As shown, the first bus bar 171 is electrically connected with the second conductive layer 162 in the second conductive substrate 160 layer through the plurality of first grooves 410, and the second bus bar 172 is electrically connected with the first conductive layer 142 in the first conductive substrate 140 layer through the plurality of second grooves 420, thereby forming a multi-electrode structure at the peripheral edge of the light adjusting piece 100 alternately, and further accelerating the color changing speed of the light adjusting piece 100.

[0066] The first conductive substrate 140 comprises a first substrate layer 141 and a first conductive layer 142, and the second conductive substrate 160 comprises a second substrate layer 161 and a second conductive layer 162. The first etching groove 181 is arranged on the circumferential side of the first groove 410, and the second etching groove 182 is arranged on the circumferential side of the second groove 420.

The first etching groove 181 at least penetrates the first conductive layer 142, and the second etching groove 182 at least penetrates the second conductive layer 162. The first etching groove 181 functions to avoid the situation that the second conductive layer 162 exposed from the bottom wall of the first groove 410 and the first conductive layer 142 exposed from the side wall of the first groove 410 come into contact and cause short circuit, and then the current is conducted to the conductive layer at the central position, so as to form an insulating barrier between the side wall of the first groove 410 and the conductive layer at the central position through the first etching groove 181. The second etching groove 182 functions to avoid the situation that the first conductive layer 142 exposed from the bottom wall of the second groove 420 and the second conductive layer 162 exposed from the side wall of the second groove 420 come into contact and cause short circuit, and then the current is conducted to the conductive layer at the central position, so as to form an insulating barrier between the side wall of the second groove 420 and the conductive layer at the central position through the second etching groove 182.

[0069] In some embodiments, as shown in Figure 9As shown, the glue layer 233 includes at least two sub-sealing glues 233a, the at least two sub-sealing glues 233a are connected to form the glue layer 233, the first bus bar 171 is partially arranged between one of the sub-sealing glues 233a and the second conductive substrate 160, and the connection position of the at least two sub-sealing glues 233a is misaligned with the first bus bar 171.

[0070] In some embodiments, the glue layer 233 includes at least two sub-sealing glues 233a, the at least two sub-sealing glues 233a are connected to form the glue layer 233, the second bus bar 172 is partially arranged between one of the sub-sealing glues 233a and the first conductive substrate 140, and the connection position of the at least two sub-sealing glues 233a is misaligned with the second bus bar 172.

[0071] In some embodiments, the glue layer 233 includes at least two sub-sealing glues 233a, the at least two sub-sealing glues 233a are connected to form the glue layer 233, the first bus bar 171 is partially arranged between one of the sub-sealing glues 233a and the second conductive substrate 160, and the connection position of the at least two sub-sealing glues 233a is misaligned with the first bus bar 171; and the second bus bar 172 is partially arranged between one of the sub-sealing glues 233a and the first conductive substrate 140, and the connection position of the at least two sub-sealing glues 233a is misaligned with the second bus bar 172.

[0072] It can be understood that the glue layer 233 can also include three, four or more sub-sealing glues 233a, which can be designed and selected as needed in actual production design, and is not limited herein.

[0073] It should be noted that, due to the arrangement of the first bus bar 171, when two sub-sealing glues 233a are arranged on the first bus bar 171, the thickness at this position will be increased, and even greater than the thickness at the center position. When the thickness difference is large, the stress at the thicker position will be large during the subsequent lamination process, thereby increasing the risk of cracking or breaking of the dimming device at this position. Therefore, the connection position of the two sub-sealing glues 233a is misaligned with the first bus bar 171, thereby reducing the thickness at the position of the first bus bar 171 and reducing the thickness difference between the position of the first bus bar 171 and the center position of the dimming device 100, thereby preventing the risk of cracking during the subsequent lamination process.

[0074] Similarly, the two sub-sealing glues 233a are misaligned at the second bus bar 172, thereby reducing the thickness difference between the position of the second bus bar 172 and the center position of the dimming device 100, and reducing the risk of cracking during the subsequent lamination process.
