[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

Similar words such as "include" or "comprise" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] Before describing in detail the dimming glass and the manufacturing method thereof provided by the embodiments of the present disclosure, it is necessary to describe the related technologies as follows:

[0039] In the related art, dye liquid crystal dimming glass needs to be designed as a hollow tempered glass structure, which mainly includes relatively arranged outdoor tempered glass and indoor tempered glass, and a dimming functional layer sandwiched between the outdoor tempered glass and the indoor tempered glass. An aluminum frame and fixing glue are also arranged between the outdoor tempered glass and the indoor tempered glass. The aluminum frame and the fixing glue are arranged around the four sides of the dimming functional layer, and the electrical connection part of the dimming functional layer is integrated into the dimming glass structure.

[0040] In the related art, the electrical connection part of the dimming functional layer is fixed in the following way: the outer side of the binding circuit board of the dimming functional layer is directly connected to the printed circuit board, the printed circuit board is fixed to the glass substrate by a buckle, and a conductive lead is welded on the printed circuit board, and the conductive lead is exposed on the side of the dimming glass. In the process of installing the dimming glass to the building facade and the skylight, the installation and construction process is relatively violent. For example, the dimming glass will be forcibly pushed in and embedded in the metal profile, causing the electrical connection leads to be squeezed and pulled between the side of the dimming glass and the metal profile, and then the pulling force is transmitted to the printed circuit board and the binding circuit board, resulting in loose electrical connection and abnormal conduction, and finally causing the dimming glass after installation to have poor dimming phenomenon (for example, unable to light up or poor contact), and this poor phenomenon occurs frequently. The disassembly and repair of the poor dimming glass after installation is troublesome and dangerous, and the replacement cost is high. Therefore, the problem of electrical connection failure caused by the installation of the dimming glass needs to be solved urgently.

[0041] In order to solve the above problems, in some related technologies, the dimming function layer mainly includes an upper and lower substrate and a liquid crystal layer located between the upper and lower substrates. Grooves are respectively opened on the upper and lower substrates, and conductive leads are placed in the grooves. The conductive leads in the grooves are squeezed and fixed by the upper and lower substrates. However, this method is only for the dimming function layer structure. For dimming glass, it also includes indoor glass and outdoor glass. It is no longer possible to achieve the effect of fixing the conductive leads by only opening grooves on the upper and lower substrates of the dimming function layer. In addition, it is necessary to groove the upper and lower substrates, which increases the production process and generates additional costs. In the assembly process, due to the height difference between the upper and lower substrates in the grooved area, the local pressure is too large, which is prone to cracking and edge collapse.

[0042] In order to solve the above problems, the embodiments of the present disclosure provide a dimming glass and a manufacturing method thereof, which can reduce the probability of the electrical connection structure of the dimming glass being damaged during the installation process and ensure the normal driving of the dimming function layer.

[0043] like Figures 1 to 4As shown, the dimming glass provided by the embodiment of the present disclosure includes: two glass substrates 100 arranged in a box, at least one dimming function layer 200 and a frame sealant 300 sandwiched between the two glass substrates 100, wherein the edge of the glass substrate 100 has a sealing area 110 not covered by the dimming function layer 200, at least one side of the dimming function layer 200 is a binding side, the dimming function layer 200 is provided with a binding circuit board 210 on the binding side, and a plurality of conductive leads 220 are connected to the binding circuit board 210; the frame sealant 300 is filled in the two glass substrates 10 0 between the sealing area 110; the conductive lead 220 includes a connecting end 221, a protruding end 222, and an extending section 223 connecting the connecting end 221 and the protruding end 222, the connecting end 221 is connected to the binding circuit board 210, the protruding end 222 extends out of the edge of the glass substrate 100, at least a portion of the extending section 223 extends along a first direction X, the first direction X is the extension direction of the binding side edge of the dimming functional layer 200, and the extending section 223 is at least partially located in the sealing area 110 and is fixed by the sealing glue 300.

[0044] In the above scheme, the electrical connection part of the dimming function layer 200 sandwiched between the two glass substrates 100 is improved, wherein the multiple conductive leads 220 connected to the binding circuit board 210 are extended along the binding side edge of the dimming function layer 200 for a distance and then extend out of the glass substrate 100, that is, the connection end 221 and the extending end 222 of the conductive lead 220 are staggered by a certain distance, and the conductive lead 220 is fixed by the frame sealing glue 300. In this way, when an external force pulls the protruding end 222 of the conductive lead 220, the conductive lead 220 is fixed by the sealing glue 300, and the protruding end 222 and the connecting end 221 are staggered by a certain distance. Compared with the solution in the related art that the conductive lead 220 is directly led out from the printed circuit board, the sealing glue 300 can better protect the conductive lead 220, so that the conductive lead 220 is not easily pulled out. Therefore, during the installation process of the dimming glass building curtain wall and the skylight provided by the embodiment of the present disclosure, the situation of electrical connection failure of the dimming function layer 200 due to the pulling of the conductive lead 220 can be reduced; and this structure is simple and effective, and compared with methods such as grooving on the glass substrate 100, the cost is lower, which can save the high cost of replacing the dimming glass due to electrical connection failure.

[0045] It should be noted here that the connecting end 221 may be at least partially or entirely located in the area covered by the frame-sealing glue 300, that is, the connecting end 221 at least partially overlaps with the orthographic projection of the frame-sealing glue 300 on the glass substrate 100; the protruding end 222 extends to the outside of the edge of the glass substrate 100, which means that the protruding end 222 is at least partially located outside the area covered by the frame-sealing glue 300, that is, at least partially, the orthographic projection of the protruding end 222 on the glass substrate 100 is located outside the frame-sealing glue.

[0046] It should be noted that, in the above scheme, at least a portion of the extension section 223 extends along the first direction X, and its main purpose is to enable the connection end 221 and the protruding end 222 to be staggered by a certain distance. The routing direction of the extension section 223 extends roughly along the first direction X, and can be completely consistent with the first direction X, or can be non-parallel to the first direction X, as long as it extends roughly along the first direction X.

[0047] The dimming function layer 200 may include at least one of a dye liquid crystal dimming layer, a polymer dispersed liquid crystal dimming layer, an electrochromic dimming layer, etc. The dimming function layer may include an upper substrate and a lower substrate and a dye liquid crystal layer or a polymer dispersed liquid crystal layer or an electrochromic layer located between the upper substrate and the lower substrate, wherein the upper substrate and the lower substrate are provided with an electric drive structure, such as a drive electrode, a thin film transistor, an alignment layer, etc., wherein the substrate of the upper and lower substrates may be any suitable substrate material such as a flexible substrate or a rigid substrate. The binding circuit board 210 is connected to the binding side of the dimming function layer 200. It should be understood that there is no limitation on the specific structure of the dimming function layer 200.

[0048] In some exemplary embodiments, Figure 1 and Figure 3 As shown, the extension section 223 is laid on the sealing area 110 of at least one of the glass substrates 100 , and at least one fixing structure 400 is fixed in the sealing area 110 , and a part of the extension section 223 is fixed to the sealing area 110 by the fixing structure 400 .

[0049] By adopting the above scheme, the conductive lead 220 is fixed by the fixing structure 400, and the fixing structure 400 is fixed in the sealing area 110. In this way, when the conductive lead 220 is pulled, its stress can be released at the fixed position of the fixing structure 400 and the glass substrate 100, so that the conductive lead 220 is subjected to the pulling stress, and the strength of the connection position between the conductive lead 220 and the binding circuit board 210 and the connection position between the binding circuit board 210 and the dimming function layer 200 will not be damaged, which effectively avoids the failure of the electrical connection method caused by directly leading out the conductive lead 220 using a printed circuit board in the related art, and can save the high cost caused by replacing the dimming glass.

[0050] In some embodiments, Figure 2 and Figure 4 As shown, the fixing structure 400 is fixed on the glass substrate 100 by means of adhesive 500. The adhesive 500 can be made of strong adhesive to enhance the fixing strength of the fixing structure 400. Thus, the fixing structure 400 can be firmly fixed on the glass substrate 100 by means of the adhesive 500 and the sealing adhesive 300.

[0051] Of course, it can be understood that the above embodiments are merely examples, and in other embodiments, the fixing method of the fixing structure 400 is not limited thereto.

[0052] In addition, illustratively, the fixing structure 400 includes a fixing clamp, and the fixing clamp includes a clamp body 420 , and a through channel 410 is provided in the clamp body 420 , and the extension section 223 is passed through the channel 410 and fixed to the channel 410 by solid glue 430 .

[0053] With the above solution, the extension section 223 of the conductive lead 220 is inserted into the channel 410 of the fixed clamp, and a solid glue 430, such as glass glue, silicone glue or resin glue, can be coated in the channel 410 in the clamp body 420, so that the conductive lead 220 is firmly fixed to the fixed clamp by the solid glue 430. Of course, it can be understood that the specific structure of the fixing structure 400 is not limited, for example, the fixing structure 400 can also be any other suitable fixing structure such as a buckle; in addition, the way in which the fixing structure 400 clamps and fixes the conductive lead 220 is not limited to the solid glue 430, and the conductive lead 220 can also be firmly clamped by the inner diameter design of the channel 410 to achieve the fixation of the conductive lead 220.

[0054] Furthermore, in some exemplary embodiments, Figure 5As shown, the clamp body 420 includes two shells 421 that can be buckled together. One side of the two shells 421 is hinged by a hinge 422, and the other side is connected by a snap assembly 423. Each shell 421 is provided with a slot 411. When the two shells 421 are buckled together, the two slots 411 cooperate to form the channel 410.

[0055] Using the above solution, if Figure 6 As shown, when assembling the dimming glass, the buckle assembly 423 can be opened to separate the two shells of the clamping member body 420 (as shown in FIG. Figure 6 (a), a solid glue 430 is applied to the A area of ​​the card slot 411, and then the conductive lead 220 is laid in the card slot 411 coated with the solid glue 430 (as shown in FIG. Figure 6 (b)), and then close the buckle assembly to make the two shells 421 buckle together (as shown in Figure 6 (c)). This structure is simple, easy to assemble, and the solid glue 430 is evenly coated. Of course, it can be understood that the clamp body 420 in the above example is a split arrangement, which can be opened or closed. In actual applications, the clamp body 420 can also be a single piece.

[0056] It should also be noted that, in the above-mentioned embodiment, the two shells in the clamping member body 420 are opened and closed by means of hinged connection on one side and snap-fit ​​connection on the other side. In other embodiments not shown, the two shells in the clamping member body 420 may also be opened and closed by other means, for example, the two shells are connected on opposite sides by snap-fit ​​connection, etc., which are not listed one by one here.

[0057] In addition, the number of the fixing structures 400 may be one or more. In order to further enhance the pulling force borne by the conductive lead 220, in some exemplary embodiments, the number of the fixing structures 400 is at least two. Of course, it can be understood that in actual applications, the specific number of the fixing structures 400 can be reasonably selected according to the actual application.

[0058] In addition, in some exemplary embodiments, the extension distance of the extension section 223 in the conductive lead 220 along the first direction X may be between 15 and 20 cm, the maximum length of the fixing structure 400 in the first direction X may be between 1 and 10 cm, and exemplary, the maximum length of the fixing structure 400 in the first direction X may be between 3 and 4 cm; the maximum height of the fixing structure 400 in the second direction perpendicular to the glass substrate is between 1 and 25 mm, and exemplary, the height in the second direction Y perpendicular to the glass substrate 100 should be less than the gap height between the two glass substrates 100, which is approximately 6 to 8 mm; the maximum width of the fixing structure 400 in the third direction perpendicular to the first direction and the second direction is between 1 and 20 mm, and exemplary, the width in the third direction Z perpendicular to the first direction X and the second direction Y is between 8 and 10 mm, and the inner diameter of the channel 410 should be greater than or equal to the cross-sectional area of ​​the plurality of conductive leads 220, and the maximum inner diameter is approximately between 1 and 10 mm, and exemplary, the inner diameter of the channel 410 is approximately between 3 and 4 mm.

[0059] It should be understood that, in practical applications, there are no specific limitations on the length of the extension section 223 and the size parameters of the fixing structure 400, and they can be reasonably selected according to actual needs.

[0060] Furthermore, in some exemplary embodiments, Figure 1 and Figure 3 As shown, the extension section 223 is configured as follows: after extending from the connection end 221, it bends toward the side where the dimming function layer 200 is located, and after extending a predetermined distance along the first direction X, it bends toward the outside of the glass substrate 100 and extends out of the glass substrate 100. In other words, the extension section 223 should be laid as much as possible toward the inside (i.e., toward the side where the dimming function layer 200 is located), so that when the frame sealant 300 is cured, it will better protect the conductive lead 220, making it more difficult for the conductive lead 220 to be pulled out.

[0061] In some embodiments, the frame sealant 300 may be made of any suitable material such as black butyl rubber. The color of the fixing structure 400 is preferably consistent with the color of the frame sealant 300.

[0062] In addition, the number of the dimming function layer 200 can be one layer or at least two layers. Figure 1 and Figure 2The structure diagram of the dimming function layer 200 having only one layer is shown. In this embodiment, at least two conductive leads 220 are connected to the binding circuit board 210, and at least two conductive leads 220 pass through the channel 410 of the same fixing clamp. In this way, the cost can be saved, the structure is simple, and the assembly is convenient.

[0063] Figure 3 and Figure 4 The structure diagram of the dimming function layer 200 is shown as two layers. In this embodiment, the dimming function layer 200 has at least two layers, and at least two conductive leads 220 are connected to the binding circuit board 210 of each dimming function layer 200, and the multiple conductive leads 220 of at least two layers of the dimming function layer 200 pass through the channel 410 of the same fixed clamp. In this way, the multiple conductive leads 220 of different dimming function layers 200 share a fixed clamp, which saves the number of the fixed clamps, reduces costs, and is easy to assemble.

[0064] It should be noted that when the dimming function layer 200 has at least two layers, multiple conductive leads 220 of the same dimming function layer 200 may share a fixing clamp, while conductive leads 220 of different dimming function layers 200 may not share the same fixing clamp.

[0065] In addition, it should be noted that, of the two glass substrates 100, one is the indoor glass substrate 100, and the other is the outdoor glass substrate 100. The conductive lead 220 of the dimming function layer 200 can be fixed to the indoor glass substrate 100 by a fixing clamp, or can be fixed to the outdoor glass substrate 100 by a fixing clamp; or, when the dimming function layer 200 is at least two layers, the conductive lead 220 corresponding to the dimming function layer 200 close to the indoor glass substrate 100 is fixed to the indoor glass substrate 100 by a fixing clamp, and the conductive lead 220 corresponding to the dimming function layer 200 close to the outdoor glass substrate 100 is fixed to the outdoor glass substrate 100 by a fixing clamp.

[0066] In addition, in the related art, the binding circuit board 210 is directly connected to the printed circuit board, the printed circuit board is snap-connected to the glass substrate 100, and the conductive lead 220 is directly led out from the printed circuit board. When the conductive lead 220 is pulled, the printed circuit board is easy to loosen. In some exemplary embodiments of the present disclosure, as shown in the figure, the binding circuit board 210 includes a conductive gasket 211, and the conductive lead 220 is directly welded to the conductive gasket 211. With such a design, since the conductive lead 220 can extend a predetermined distance along the first direction X, and / or the conductive lead 220 is fixed by the fixing structure 400, and the conductive lead 220 is also fixed by the frame sealing glue 300, therefore, in the embodiment of the present disclosure, a printed circuit board may no longer be provided, but the conductive lead 220 may be directly welded to the conductive gasket of the binding circuit board 210, thereby reducing costs, being applicable to products of various sizes, and avoiding the phenomenon that the printed circuit board is easy to loosen.

[0067] In some embodiments, Figure 1 and Figure 3 As shown, an anti-oxidation protective layer 224 is wrapped around the welding position of the conductive lead 220 and the conductive pad to prevent oxidation of the welding position. The anti-oxidation protective layer 224 can be made of any suitable material such as acetate cloth.

[0068] In addition, in an exemplary embodiment, Figures 1 to 4 As shown, the dimming glass further includes a support frame 600, the support frame 600 is located between the two glass substrates 100 and at the periphery of the dimming functional layer 200, and the sealing area 110 is located at the periphery of the support frame 600. The support frame 600 can be a metal frame such as an aluminum frame. The strength of the hollow tempered structure is improved by the support frame 600. Among them, the fixed structure 400 and the support frame 600 may not be bonded.

[0069] Another aspect of the present disclosure further provides a method for manufacturing a dimming glass, which is used to manufacture the dimming glass provided by the present disclosure, and the method comprises the following steps:

[0070] Step S01, laminating the dimming function layer 200 on one of the glass substrates 100;

[0071] The dimming functional layer 200 can be bonded to the surface of the indoor glass substrate 100 at high temperature and high pressure through a PVB (PolyViny Butyral) film or other adhesive layer;

[0072] Step S02, laying the plurality of conductive leads 220 on the binding side of the dimming functional layer 200 in the sealing area 110;

[0073] The conductive lead 220 is laid on the surface of the indoor glass substrate 100;

[0074] Step S03 , placing another glass substrate 100 on the dimming function layer 200 , and filling the frame sealant 300 between the sealing areas 110 of the two glass substrates 100 , wherein the extension section 223 is fixed by the frame sealant 300 .

[0075] The outdoor glass substrate 100 can be placed on the dimming function layer 200, and the frame sealant 300 is injected into the gap between the indoor glass substrate 100 and the outdoor substrate. After the frame sealant 300 is cured, the excess frame sealant 300 on the outside of the glass substrate 100 is trimmed.

[0076] Illustratively, after the step S02 , the method further includes: step S021 , fixing the extension section 223 by the fixing structure 400 , and fixing the fixing structure 400 on the glass substrate 100 by an adhesive 500 .

[0077] Specifically, the step S021 includes: opening the two shells of the fixed structure 400, and applying solid glue 430 (glass glue, silicone glue or resin glue, etc.) in the card slot, laying the conductive lead 220 in the card slot coated with solid glue 430, and closing the snap assembly, applying strong glue to the bottom of the closed fixed structure 400, and sticking it to the surface of the glass substrate 100.

[0078] The following Figure 1 and Figure 3 Taking the embodiment shown as an example, the manufacturing method of the dimming glass provided by the embodiment of the present disclosure is described in more detail. The method comprises the following steps:

[0079] Step S01, welding the conductive lead 220 to the conductive pad of the binding circuit board 210 of the dimming function layer 200, using a PVB (PolyVinyl Butyral, polyvinyl butyral) film or other adhesive layer to adhere the dimming function layer 200 (Cell1 and Cell2 in the figure) to the indoor tempered glass surface at high temperature and high pressure, and using an anti-oxidation layer such as acetate cloth to wrap the welding position to prevent oxidation;

[0080] Step S02, laying the conductive lead 220 on the indoor glass surface, with at least one section being laid as close to one side of the support frame as possible;

[0081] Step S021, open the two shells of the fixing clamp, apply solid glue 430 (glass glue, silicone glue or resin glue, etc.) in the card slot, lay the conductive lead 220 in the card slot coated with solid glue 430, close the buckle assembly, apply strong glue to the bottom of the fixing clamp after closing, and stick it to the surface of the glass substrate 100;

[0082] Step S03, placing the outdoor glass substrate 100 on the dimming function layer 200, and injecting the sealant 300 into the gap between the indoor glass substrate 100 and the outdoor substrate, and trimming the excess sealant 300 on the outside of the glass substrate 100 after the sealant 300 is cured to obtain dimming glass.

[0083] The dimming glass provided by the embodiment of the present disclosure can reduce the probability of the electrical connection structure of the dimming glass being damaged during the installation process, and ensure that the dimming function layer 200 is driven normally.

[0084] The present disclosure has conducted a test experiment on the tensile stress borne by the conductive lead 220 of the dimming glass provided by the embodiment of the present disclosure and the dimming glass in the related art.

[0085] In the test experiment, the present disclosure provides dimming glasses as Example 1 and Example 2, wherein the number of fixed clamps used in Example 1 is 2, and the number of fixed clamps used in Example 2 is 1. A dimming glass in the related art is used as a control example.

[0086] The testing process is as follows:

[0087] First, the dimming glass is powered on, so that the dimming function layer 200 inside the glass is in a bright state;

[0088] Then, place the smart glass on the ground and fix it, and use a tension scale to pull the external lead wire in the direction perpendicular to the ground. This can simulate the squeezing and pulling process of the surrounding metal profiles on the smart glass during the actual installation process.

[0089] Then, the external conductive lead 220 is pulled forcefully until the dimming function layer 200 inside the dimming glass fails. When the transmittance suddenly decreases, it is considered that the internal electrical connection fails.

[0090] The test results are:

[0091] The conductive lead 220 of the dimming glass in Example 1 can withstand a pulling force of more than 40 kg. The force point of the lead during the pulling process is located at the bonding point between the fixed structure 400 and the glass substrate 100. When the fixed structure 400 is broken, the external force will be transmitted to the welding position between the printed circuit board and the conductive lead 220.

[0092] The conductive lead 220 of the dimming glass in Example 2 can withstand a pulling force of more than 34 kg. The force point of the lead during the pulling process is located at the bonding point between the fixed structure 400 and the glass substrate 100. When the fixed structure 400 is broken, the external force will be transmitted to the welding position between the printed circuit board and the conductive lead 220.

[0093] In the control example, the conductive lead 220 of the dimming glass can withstand a tensile force of more than 6 kg.

[0094] It can be seen that the strength of the conductive lead 220 in the dimming glass provided in the embodiment of the present disclosure is increased by 7 times. During the actual construction and installation of the dimming glass, the friction, extrusion and pulling force between the side of the dimming glass and the metal profile frame is about 5-15Kg. Therefore, the dimming glass and its manufacturing method provided in the embodiment of the present disclosure can effectively reduce the probability of the electrical connection structure of the dimming glass being damaged during the installation process, and ensure the normal driving of the dimming function layer 200.
