[0029] The following will be described in detail Figure 1 The present application is further described in detail in conjunction with Fig. 5-2.
[0030] The first aspect of the present application provides an electrochromic device, which is combined with Figure 1and Figure 3 As shown in the drawings, the electrochromic device comprises: a film sheet 100 and an attaching assembly 200; the attaching assembly 200 comprises: a first attaching part (see the first bus bar 210 in Figure 2 and / or the first adhesive layer 270), a second attaching part (see the second bus bar 220 in Figure 2 and / or the second adhesive layer 280), a third attaching part (see the third bus bar 230 in Figure 2 and / or the third adhesive layer 250), and a fourth attaching part (see the fourth bus bar 240 in Figure 2 and / or the fourth adhesive layer 260); the first attaching part (210, 270), the second attaching part (220, 280), the third attaching part (230, 250), and the fourth attaching part (240, 260) are respectively attached to the edge region of the film sheet 100, the first attaching part and the second attaching part overlap to form a first overlap part (see the first bus bar overlap part 201 in Figure 2 and / or the second adhesive overlap part 204), and the third attaching part and the fourth attaching part overlap to form a second overlap part (see the second bus bar overlap part 202 in Figure 2 and / or the first adhesive overlap part 203); the projection of the first overlap part (201, 204) on the plane of the film sheet 100 and the projection of the second overlap part (202, 203) on the plane of the film sheet 100 are staggered with each other. In some embodiments, the projection of the first overlap part on the plane of the film sheet 100 and the projection of the second overlap part on the plane of the film sheet 100 are completely staggered.
[0031] Specifically, the first attaching part and the second attaching part can be configured as attaching materials of the same material, the third attaching part and the fourth attaching part can be configured as attaching materials of the same material, and the first overlap part and the second overlap part are staggered with each other, so as to improve the thickness uniformity of the electrochromic device and reduce the thickness difference of each point in the edge region of the electrochromic device. Preferably, the first overlap part and the second overlap part are completely staggered, that is, the projection of the first overlap part on the plane of the film sheet 100 and the projection of the second overlap part on the plane of the film sheet 100 are completely not coincident, so as to minimize the product thickness difference, improve the thickness uniformity, and reduce the risk of glass cracking during the film sheet process.
[0032] In the embodiment of the utility model, as shown in Figure 2 the first attaching part comprises the first bus bar 210, the second attaching part comprises the second bus bar 220, the first overlap part comprises the first bus bar overlap part 201 formed by the overlap of the first bus bar 210 and the second bus bar 220.
[0033] In one embodiment, the diaphragm 100 includes a first conductive layer, a color-changing layer, and a second conductive layer sequentially disposed therefrom. A first busbar 210 and a second busbar 220 are located at the edge portion of the same conductive layer and extend along the edge portion of the same conductive layer, and are electrically connected to the same conductive layer. The first busbar 210 and the second busbar 220 directly contact and overlap to form a busbar overlap portion I201. A third attachment and a fourth attachment are located at the edge portion of another conductive layer and extend along the edge portion of the same conductive layer.
[0034] In some other embodiments, the third attachment, the fourth attachment, the first attachment, and the second attachment are all located on the same conductive layer. That is, the first busbar overlap 201 and the second overlap are located on the same conductive layer, and the first busbar overlap 201 and the second overlap, which are on the same conductive layer, will be completely misaligned. In this case, the third attachment can be a busbar or a waterproof adhesive.
[0035] It is worth noting that in the above embodiments, the first overlapping portion can be formed by directly overlapping the first and second attachments, or by the projection portions of the ends of the first and second attachments that are close to each other overlapping in the plane of the electrochromic film, forming an overlapping portion in three-dimensional space. For example, the first attachment is disposed on the first surface of the film, and the second attachment is disposed on the second surface of the film. The first and second surfaces are two surfaces perpendicular to the thickness direction of the film. The projection portions of the first and second attachments overlapping in the plane of the film form an overlapping portion through the film. Similarly, the second overlapping portion can also be formed in the same way as described above.
[0036] like Figure 2 As shown, in some preferred embodiments, the third attachment includes a third busbar 230, and the fourth attachment includes a fourth busbar 240. The second overlap includes a second busbar overlap 202 formed by the overlap of the third busbar 230 and the fourth busbar 240.
[0037] In some implementations, the first busbar 210 and the second busbar 220 are disposed on the first conductive layer, and the third busbar 230 and the fourth busbar 240 are disposed on the same conductive layer. Each busbar is sequentially overlapped end-to-end across the entire edge region of the electrochromic membrane. The overlapping portions of the busbars form overlap sections; that is, a third overlap section is formed between the second and third busbars, and a fourth overlap section is formed between the first and fourth busbars. The projections of each overlap section onto the plane of the membrane are completely staggered.
[0038] In other embodiments, such as Figure 2As shown, the first bus bar 210 and the second bus bar 220 are arranged on the first conductive layer, the third bus bar 230 and the fourth bus bar 240 are arranged on the second conductive layer, that is, the first bus bar lap joint part 201 is arranged on the first conductive layer, the second bus bar lap joint part 202 is arranged on the second conductive layer, the projection of the first bus bar lap joint part 201 and the projection of the second bus bar lap joint part 202 on the plane of the diaphragm 100 are staggered, thereby avoiding the increase of the local thickness caused by the position overlap of the first bus bar lap joint part 201 and the second bus bar lap joint part 202, reducing the product thickness difference, and improving the uniformity of the entire thickness of the electrochromic device.
[0039] In combination Figure 1 As shown, in some embodiments, the third adhesive member includes a third adhesive layer 250, and the fourth adhesive member includes a fourth adhesive layer 260; the second lap joint part includes a first adhesive material lap joint part 203 formed by the lap joint of the third adhesive layer 250 and the fourth adhesive layer 260.
[0040] In combination Figure 1 As shown, in some embodiments, the first adhesive member includes a first adhesive layer 270, and the second adhesive member includes a second adhesive layer 280. In an optional implementation, the first lap joint part includes a second adhesive material lap joint part 204 formed by the lap joint of the first adhesive layer 270 and the second adhesive layer 280.
[0041] In combination Figure 2 As shown, in an optional implementation, at least one of the projection of the first bus bar lap joint part 201 and the projection of the second bus bar lap joint part 202 on the plane of the diaphragm 100 is staggered with the projection of the first adhesive material lap joint part 203 on the plane of the diaphragm 100, thereby avoiding the excessive local thickness of the electrochromic device and reducing the product thickness difference.
[0042] In combination Figure 2 As shown, in an optional implementation, the first adhesive member includes the first bus bar 210, the second adhesive member includes the second bus bar 220, the third adhesive layer 250 covers the first bus bar 210, the fourth adhesive layer 260 covers the second bus bar 220, the first adhesive layer 270 covers the third bus bar 230, and the second adhesive layer 280 covers the fourth bus bar 240, thereby playing a role of protecting the first bus bar 210, the second bus bar 220, the third bus bar 230, and the fourth bus bar 240. It is worth noting that, in the embodiments of the present application, since the lap joint parts are staggered with each other, as shown in Figure 2 As shown, the third adhesive layer 250 covers the first bus bar 210 and extends to cover part of the second bus bar 220; or as shown in Figure 3 As shown, the fourth adhesive layer 260 covers the second bus bar 220 and extends to cover part of the first bus bar 210. Among them Figure 3As a top view of the electrochromic device, the first bus bar 210 and the second bus bar 220 should be visually invisible because they are covered by the combination of the third adhesive layer 250 and the fourth adhesive layer 260. For the convenience of understanding, the first bus bar 210 and the second bus bar 220 are represented by dashed lines. For the convenience of understanding, the first adhesive layer overlap 203 and the first bus bar overlap 201 are filled with different fill patterns in the figure, which only facilitates the understanding of the relative positions of the two by those skilled in the art, and does not limit the materials and shapes thereof.
[0043] The projections of the first bus bar overlap 201 and the second adhesive layer overlap 204 on the plane of the diaphragm 100 are misaligned, and at least one of the first bus bar overlap 201 and the second adhesive layer overlap 204 and the second overlap are misaligned on the plane of the diaphragm 100, thereby reducing the product thickness difference.
[0044] Of course, the first overlap and the second overlap can each include a plurality of bus bar overlaps formed by two bus bars and a plurality of adhesive layer overlaps formed by two adhesive layers, in other words, the first attachment and the second attachment can each include a bus bar and form a bus bar overlap by two bus bars. Or the first attachment and the second attachment each include an adhesive layer and form an adhesive layer overlap by two adhesive layers, and for the same reason, the second overlap can include at least one of the bus bar overlap and the adhesive layer overlap. In the best embodiment, the projections of the plurality of bus bar overlaps and the plurality of adhesive layer overlaps on the plane of the diaphragm 100 are all misaligned, at which time the thickness difference of each point of the device is minimized and the overall thickness of the product is more uniform.
[0045] As shown in FIG. 4-1, in the embodiments of the present application, the diaphragm 100 is configured with a plurality of spaced-apart electrodes 101, and there is a gap 102 between two adjacent electrodes 101; the gap 102 extends at least through part of the thickness of the diaphragm in the thickness direction of the diaphragm, and preferably the gap 102 extends through the thickness direction of the diaphragm. An insulating adhesive 1021 is provided at the gap 102 to prevent the two-sided bus bars from being bonded and contacting to short circuit. The projection of at least one of the first overlap and the second overlap on the plane of the diaphragm 100 is located within the gap 102, which utilizes the internal space of the gap 102 to accommodate at least one of the first overlap and the second overlap, thereby reducing the product thickness at the overlap position and facilitating the reduction of the product thickness difference.
[0046] In some optional embodiments, the length of the first overlap and the second overlap extending along the edge of the diaphragm is less than the length of the gap 102 extending along the edge of the diaphragm.
[0047] In the embodiment, the first lap joint and the second lap joint are located in different notches in the projection of the diaphragm plane, the width of the first lap joint and the second lap joint is set to be smaller than the width of the notch, that is, the first lap joint and the second lap joint are accommodated in the notch in the width direction, avoiding the lap joint and the diaphragm outside the notch to increase the local thickness, so that the thickness of the entire diaphragm is more uniform.
[0048] For example, as shown in FIG. 4-2, the width of the notch 102 is D1, the first lap joint includes a first bus bar lap joint 201, the width of the first bus bar lap joint 201 is D2, and D1 is greater than D2; the second lap joint includes a second bus bar lap joint 202, the width of the second bus bar lap joint 202 is D3, and D1 is greater than D3.
[0049] For example, as shown in FIG. 5-2, the width of the notch is D1, the second lap joint includes a first adhesive lap joint 203, the width of the first adhesive lap joint 203 is D4, and D1 is greater than D4; the first lap joint includes a second adhesive lap joint 204, the width of the second adhesive lap joint 204 is D5, and D1 is greater than D5.
[0050] Further, as Figure 3 As shown in FIG. 5-1, at least one of the first lap joint and the second lap joint includes a bus bar lap joint formed by a bus bar, the bus bar can be made of copper foil, silver or other metal materials; the projection of the bus bar lap joint in the diaphragm 100 plane is located in the projection of the electrode 101 in the diaphragm 100 plane. As shown in FIG. 5-1, the first bus bar lap joint 201 and the second bus bar lap joint 202 are respectively arranged on different electrodes 101 of the diaphragm 100, and are respectively electrically connected with the electrodes 101.
[0051] When the first and second attachments are bus bars, that is, for conduction, if the length of the lap joint is small, it is easy to fall off and cause a break. Since the size of the notch 102 between the two adjacent electrodes 101 is small, it cannot meet the lap joint length requirement. In order to ensure that the lap length of the bus bar lap joint can meet the technical requirements, the projection of the bus bar lap joint in the diaphragm 100 plane is located in the projection of the electrode 101 in the diaphragm 100 plane, in other words, the lap joint of the first and second attachments is connected with the electrode, and the surface of the electrode 101 has enough space to meet the length requirement of the bus bar lap joint, which is beneficial to reduce the risk of breakage at the bus bar lap joint.
[0052] In an optional embodiment, the bus bar lap joint is located at a straight edge of the diaphragm 100.
[0053] The edge region of the electrochromic film includes straight edge portions and curved corner portions, and the first and second adhesive members are arranged along the edge positions of the entire film. When the first and second adhesive members are bus bars such as copper foils, the ductility of the metal such as copper foil is used to overcome the wrinkles at the corners when the first or second adhesive member is attached to the corners. Therefore, the bus bar at the corner has a large internal stress due to the ductility, and if the lap portion of the bus bar is arranged at the corner of the film, the large stress can easily pull the first or second adhesive member off, resulting in failure of the lap of the first and second adhesive members. Therefore, the lap portion is arranged at the straight edge portion, and the lap portion formed by the bus bar is preferably arranged at the straight edge portion of the film, so that the lap of the entire film is more stable and less likely to fail.
[0054] In an optional embodiment, as shown in FIG. 5-1, at least one of the first and second lap portions includes a glue lap portion formed by a waterproof glue, and an example is the first glue lap portion 203 and the second glue lap portion 204. At least one of the glue lap portions is projected into the notch 102 in the plane of the film 100. Preferably, the projections of the first and second glue lap portions 203 and 204 in the plane of the film 100 are both located in the notch 102. As shown in FIG. 5-1, when the projection of the bus bar lap portion in the plane of the film 100 is located in the projection of the electrode 101 in the plane of the film 100, the glue lap portion is arranged in the notch 102, which ensures the lap length of the bus bar and reduces the product thickness at the glue lap position.
[0055] In an optional embodiment, the lap width of the glue lap portion at the corner of the adhesive assembly 200 is 2-3 mm, which is smaller than the 10 mm x 10 mm lap portion formed by the complete lap of the glue at the corner position, and the area of the lap portion is reduced to 2 mm x 2 mm-3 mm x 3 mm, reducing the area of the glue lap portion stack.
[0056] Further, the film sheet 100 is provided with adhesive overlapping parts on two sides respectively, the projections of the adhesive overlapping parts on the two sides on the plane where the film sheet 100 is located have staggered areas and overlapping areas; in the staggered areas, the projections of the adhesive overlapping parts on the two sides on the plane where the film sheet 100 is located are staggered; in the overlapping areas, the projections of the adhesive overlapping parts on the two sides on the plane where the film sheet 100 is located are coincident, and there is no copper foil in the overlapping areas. In other words, the projections of the adhesive overlapping parts on the two sides of the film sheet 100 on the plane where the film sheet 100 is located are partially overlapped, the projection of the copper foil on the plane where the film sheet 100 is located is staggered with the overlapping areas of the projections of the adhesive overlapping parts on the two sides of the film sheet 100 on the plane where the film sheet 100 is located, that is, there is no copper foil in the overlapping areas of the projections of the adhesive overlapping parts on the two sides of the film sheet 100 on the plane where the film sheet 100 is located, so as to avoid the increase of local thickness caused by the overlapping of the adhesive overlapping parts and the copper foil, and facilitate the reduction of product thickness difference.

The substrate layer comprises a first substrate layer and a second substrate layer, and the electrochromic device is sandwiched between the first substrate layer and the second substrate layer. The first substrate layer or the second substrate layer is fixedly connected to the electrochromic device through an adhesive layer, such as PVB (Polyvinyl Butyral) or the like. In some preferred embodiments, the substrate layer is made of glass or organic glass or the like transparent material. The electrochromic device is laminated from the electrochromic device, the first substrate layer and the second substrate layer. Since the electrochromic device is used, all the advantages of the electrochromic device are achieved, and the risk of substrate layer cracking during lamination is reduced.
[0058] In some preferred embodiments, the edge area of the substrate layer of the electrochromic device is provided with a shielding layer, and the shielding layer corresponds to the attachment assembly 200, that is, the projection of the attachment assembly 200 on the plane where the electrochromic film sheet is located is within the projection of the shielding layer on the plane where the electrochromic film sheet is located.
