Description

Electrochromic device, electrochromic device and electrochromic product

Technical Field

The application relates to the technical field of electrochromic, and particularly provides an electrochromic device, an electrochromic device and an electrochromic product.

Background

Electrochromic phenomenon refers to reversible color change of materials under the action of an external electric field; electrochromic is essentially a phenomenon that a material undergoes oxidation-reduction reaction under the action of an external electric field and current, so that the structure of the material is changed, and further, the absorption spectrum and optical properties (such as absorptivity, transmissivity and reflectivity) are changed, and the material is expressed as reversible changes in color and transparency in appearance. In recent years, electrochromic devices are widely applied to the fields of energy-saving windows, automobile rearview mirrors, display devices, mobile terminals and the like, and have good market application prospects.

Electrochromic materials are extremely sensitive and therefore require a tight seal. In the prior art, a sealing colloid is generally arranged at the peripheral edge of the electrochromic device to prevent water vapor or other substances in the external environment from entering the inside of the electrochromic device from the side, so that the electrochromic material is damaged and the device fails. However, this requires an additional sealant, which increases the device manufacturing process and reduces the production efficiency.

Specifically, two ends of the conductive component 1 in the first direction X are respectively connected with the first conductive base layer 2 and the second conductive base layer 4, where two ends of the conductive component 1 are two ends of the conductive component 1 as a whole, so as to ensure that the conductive component 1 can form a seal with the electrochromic layer 3.

For example, referring to fig. 2, the conductive assembly 1 may include only the first conductive connection member 5, and both ends of the conductive assembly 1 are both ends of the first conductive connection member 5, and both ends of the first conductive connection member 5 are connected with the first conductive base layer 2 and the second conductive base layer 4, respectively, such that the first conductive connection member 5 can form an effective seal against the side surface of the electrochromic layer 3.

Alternatively, referring to fig. 7, 8 and 11, the conductive assembly 1 may further include one or more second conductive connectors 7 arranged in sequence along the first direction X in addition to the first conductive connector 5. When the conductive component 1 comprises a first conductive connecting piece 5 and a second conductive connecting piece 7, one end of the whole conductive component 1 is one end of the first conductive connecting piece 5, which is close to the electrochromic layer 3, and the other end of the conductive component 1 is one end of the second conductive connecting piece 7, which is far away from the electrochromic layer 3; the conductive assembly 1 as a whole is able to form an effective seal against the sides of the electrochromic layer 3.

In some embodiments, referring to fig. 2 and 5, the first conductive connection member 5 is connected to the first conductive base layer 2 and the second conductive base layer 4 at both ends thereof in the first direction X, respectively; wherein,

the conductive portion 5022 of the first conductive connector 5 in the first groove 601 passes through the first groove 601 and is connected to the peripheral edge of the second conductive base layer 4 near the electrochromic layer 3, so that the conductive layer 501 and the second conductive base layer 4 are electrically connected; and/or the number of the groups of groups,

the conductive portion 5022 of the first conductive connector 5 in the second groove 602 passes through the second groove 602 and is connected to the first conductive base layer 2 near the peripheral edge of the electrochromic layer 3, so that the conductive layer 501 is electrically connected with the first conductive base layer 2.

Specifically, when the first conductive connection member 5 is disposed, the conductive portion 5022 needs to be connected to the first conductive base layer 22 of the first conductive base layer 2 or the second conductive base layer 42 of the second conductive base layer 4 to ensure that the conductive layer 501 is electrically connected to the first conductive base layer 2 or the second conductive base layer 4 through the conductive portion 5022.

Here, the number of the conductive portions 5022 is not limited, and the adhesive layer 502 may have only one conductive portion 5022, or the adhesive layer 502 may have a plurality of conductive portions 5022; so that the conductive layer 501 can be electrically connected to the first conductive base layer 2 or the second conductive base layer 4 through one or more conductive portions 5022.

In some embodiments, referring to fig. 2, 7, and 8, in the first groove 601, one end of the insulating portion 5021 of the first conductive connector 5 is connected to the peripheral edge of the first conductive base layer 2 away from the electrochromic layer 3, and the other end of the insulating portion 5021 of the first conductive connector 5 is connected to the peripheral edge of the second conductive base layer 4 near the electrochromic layer 3; and/or the number of the groups of groups,

in the second groove 602, one end of the insulating portion 5021 of the first conductive connecting piece 5 is connected to the peripheral edge of the second conductive base layer 4 away from the electrochromic layer 3, and the other end of the insulating portion 5021 of the first conductive connecting piece 5 is connected to the peripheral edge of the first conductive base layer 2 near the electrochromic layer 3.

As can be appreciated, in the first groove 601, the insulating portion 5021 can isolate the conductive layer 501 from the first conductive base layer 22 of the first conductive base layer 2, so that the conductive layer 501 is electrically connected only to the second conductive base layer 42 of the second conductive base layer 4. In the second groove 602, the insulating portion 5021 can isolate the conductive layer 501 from the second conductive base layer 42 of the second conductive base layer 4, so that the conductive layer 501 is electrically connected only to the first conductive base layer 22 of the first conductive base layer 2; the first conductive base layer 22 and the second conductive base layer 42 are prevented from being in contact with each other to generate a short circuit, so that the stability of the electrochromic device 1000 is ensured.

The insulating portion 5021 covers the first conductive substrate layer 2 and the second conductive substrate layer 4 in the first groove 601 and the second groove 602 at the same time, that is, the insulating portion 5021 can form a seal on the side surface of the electrochromic layer 3 in the first direction X, so that water vapor of external environment is prevented from entering the electrochromic device 1000 from the side surface, and the service life of a product is prolonged.

Referring to fig. 5, in some embodiments, the adhesive layer 502 of the first conductive connector 5 includes a first conductive portion 5023, a second conductive portion 5024, and an insulating portion 5021 connected between the first conductive portion 5023 and the second conductive portion 5024, which are sequentially arranged; wherein,

the conductive layer 501 is electrically connected with the second conductive base layer 4 through the second conductive portion 5024, and two ends of the first conductive portion 5023 in the first direction X are disposed on the first conductive base layer 2; and/or the number of the groups of groups,

the conductive layer 501 is electrically connected to the first conductive base layer 2 through the second conductive portion 5024, and both ends of the first conductive portion 5023 in the first direction X are disposed on the second conductive base layer 4.

Specifically, in some embodiments, in the first groove 601, both ends of the second conductive portion 5024 are connected to the peripheral edge of the side of the second conductive base layer 4 near the electrochromic layer 3, and both ends of the first conductive portion 5023 are connected to the peripheral edge of the side of the first conductive base layer 2 far from the electrochromic layer 3; namely, the conductive layer 501 is electrically connected to the second conductive base layer 4 only through the second conductive portion 5024; at this time, the first conductive portion 5023 does not serve as an electrical connection and only serves as an adhesive.

In other embodiments, in the second groove 602, both ends of the second conductive portion 5024 are connected to the peripheral edge of the side of the first conductive substrate layer 2 near the electrochromic layer 3, and both ends of the first conductive portion 5023 are connected to the peripheral edge of the side of the second conductive substrate layer 4 far from the electrochromic layer 3; namely, the conductive layer 501 is electrically connected with the first conductive base layer 2 only through the second conductive portion 5024; at this time, the first conductive portion 5023 does not serve as an electrical connection and only serves as an adhesive.

In some embodiments, referring to fig. 2, in the first groove 601, the first conductive connection 5 partially covers the first conductive base layer 2, and the width of the portion of the first conductive connection 5 covering the first conductive base layer 2 ranges from 0 to 1 mm. The width of the portion of the first conductive connecting member 5 covering the first conductive base layer 2 is the length of the first conductive connecting member 5 in the first direction X. By providing the first conductive connection 5 to partially cover the edge of the first conductive base layer 2, the first conductive connection 5 has good connectivity with the first conductive base layer 2, so as to avoid that the first conductive connection 5 is separated or even separated from the surface of the first conductive base layer 2 due to larger stress on the portion of the first conductive connection 5 covered on the first conductive base layer 2 when the electrochromic device 1000 is pressed, because the thickness of the peripheral edge of the first conductive base layer 2 is larger.

In other embodiments, in the second groove 602, the first conductive connection member 5 partially covers the second conductive base layer 4, and the width of the portion of the first conductive connection member 5 covering the second conductive base layer 4 ranges from 0 to 1 mm. The width of the portion of the first conductive connecting member 5 covering the second conductive base layer 4 is the length of the first conductive connecting member 5 in the first direction X. By providing the first conductive connection 5 to partially cover the edge of the second conductive base layer 4, the first conductive connection 5 has good connectivity with the second conductive base layer 4, so as to avoid that the first conductive connection 5 is separated or even separated from the surface of the second conductive base layer 4 due to the larger stress on the portion of the first conductive connection 5 covering the second conductive base layer 4 due to the larger thickness at the peripheral edge of the second conductive base layer 4 when the electrochromic device 1000 is pressed.

In some embodiments, the first conductive connecting piece 5 is formed by stacking the conductive layer 501 and the adhesive layer 502, the adhesive layer 502 is formed by pre-forming conductive glue, and then the insulating part 5021 is formed by disposing partial conductive glue and filling insulating glue, so that the manufacturing is more convenient;

In other embodiments, the first conductive connecting piece 5 is formed by laminating the conductive layer 501 and the adhesive layer 502, and the adhesive layer 502 is formed by pre-forming conductive adhesive, and then an insulating adhesive is further disposed on a part of the conductive adhesive to form the insulating portion 5021.

Therefore, the first conductive portion 5023 and the second conductive portion 5024 are correspondingly formed on two sides of the insulating portion 5021, and do not affect the conduction and sealing effect of the first conductive connector 5.

Referring to fig. 8-11, in some embodiments, the conductive assembly 1 further includes at least one second conductive connecting member 7, wherein the first conductive connecting member 5 and the second conductive connecting member 7 are sequentially arranged on the peripheral edge of the first conductive base layer 2 along the first direction X, and the second conductive connecting member 7 is electrically connected to the first conductive base layer 2; and/or the number of the groups of groups,

in other embodiments, the first conductive connecting piece 5 and the second conductive connecting piece 7 are sequentially arranged on the peripheral edge of the second conductive base layer 4, and the second conductive connecting piece 7 is electrically connected with the second conductive base layer 4.

As can be understood, referring to fig. 12, the peripheral edge of the electrochromic device 1000 has an irregular structure, and at the irregular edge, the first conductive base layer 2, the electrochromic layer 3 and the second conductive base layer 4 all have irregular shapes, so when the conductive component 1 is disposed at the structure, if only one first conductive connecting piece 5 is used for bonding, the width of the first conductive connecting piece 5 needs to be designed to be wider, and the phenomenon that the conductive component 1 generates wrinkles during attachment easily occurs, resulting in local uneven product. Therefore, in the case where the width of the portion to be bonded of the peripheral edge of the electrochromic device 1000 is the same, by providing the first conductive connecting member 5 in combination with one or more second conductive connecting members 7, the widths of the first conductive connecting member 5 and the second conductive connecting member 7 are necessarily both smaller than the width when only one first conductive connecting member 5 is provided, and the width of the first conductive connecting member 5 is the length of the first conductive connecting member 5 in the first direction X; the first conductive connecting piece 5 and the second conductive connecting piece 7 are easy to attach, the operation difficulty is reduced, and the peripheral edge of the electrochromic device 1000 is smoother. Here, the width of the first conductive connection 5 and the width of the second conductive connection 7 are the lengths of the first conductive connection 5 in the first direction X.

In some embodiments, referring to fig. 7 and 8, in the first groove 601, the length of the portion of the second conductive base layer 4 that extends outward beyond the electrochromic layer 3 in the first direction X ranges from 2 to 10 millimeters. By arranging the first conductive connecting piece 5 and the second conductive connecting piece 7 to cover the peripheral edge of the second conductive basal layer 4, the first conductive connecting piece 5 and the second conductive connecting piece 7 are easy to attach, wrinkling of the first conductive connecting piece 5 or the second conductive connecting piece 7 is avoided, and the peripheral edge of the electrochromic device 1000 is smoother.

In the second groove 602, the length of the portion of the first conductive base layer 2 that extends outward in the first direction X beyond the electrochromic layer 3 ranges from 2 to 10 millimeters. By arranging the first conductive connecting piece 5 and the second conductive connecting piece 7 to cover the peripheral edge of the first conductive basal layer 2, the first conductive connecting piece 5 and the second conductive connecting piece 7 can be easily attached, the first conductive connecting piece 5 or the second conductive connecting piece 7 is prevented from wrinkling, and the peripheral edge of the first electrochromic device 1000 is smoother.

Specifically, the second conductive connection member 7 has a double-layer structure, and the second conductive connection member 7 includes a second conductive layer 701 and a second adhesive layer 702 that are stacked; and here, the second adhesive layer 702 may have conductivity as a whole; alternatively, the second adhesive layer 702 may be partially insulating and partially conductive, so that the second conductive connection member 7 can be electrically connected to the first conductive base layer 2 or the second conductive base layer 4.

Referring to fig. 7 and 8, in some embodiments, the conductive assembly 1 includes a first conductive connector 5 and a second conductive connector 7 that are at least partially stacked, with an electrical connection being formed between the first conductive connector 5 and the second conductive connector 7; wherein,

along the first direction X, one end of the first conductive connecting piece 5, which is far away from the second conductive connecting piece 7, is connected to the peripheral edge of the first conductive base layer 2, which is far away from the electrochromic layer 3, and one end of the second conductive connecting piece 7, which is far away from the first conductive connecting piece 5, is arranged on the peripheral edge of the second conductive base layer 4, which is near to the electrochromic layer 3; and/or the number of the groups of groups,

along the first direction X, an end of the first conductive connecting piece 5 away from the second conductive connecting piece 7 is connected to a peripheral edge of the second conductive base layer 4 on a side away from the electrochromic layer 3, and an end of the second conductive connecting piece 7 away from the first conductive connecting piece 5 is disposed on a peripheral edge of the first conductive base layer 2 on a side close to the electrochromic layer 3.

In some embodiments, the second adhesive layer 702 of the second conductive connecting member 7 is made of conductive adhesive, and referring to fig. 7 and 8, adjacent first conductive connecting members 5 and second conductive connecting members 7 are stacked and connected, so that the first conductive connecting members 5 and the second conductive connecting members 7 form electrical conduction, and it is more convenient to arrange the extraction electrode 8 on any one of the first conductive connecting members 5 and the second conductive connecting members 7. The first conductive connecting piece 5 and the second conductive connecting piece 7 are connected in a laminated mode, and the bonding stability of the first conductive connecting piece 5 and the second conductive connecting piece 7 can be improved.

The specific lamination arrangement manner of the first conductive connection member 5 and the second conductive connection member 7 is not limited, and referring to fig. 7, for example, the first conductive connection member 5 may be first arranged, and then one end of the second conductive connection member 7 is laminated and bonded on the conductive layer 501 of the first conductive connection member 5; alternatively, referring to fig. 8, the second conductive connector 7 may be provided first, and then one end of the first conductive connector 5 may be laminated and bonded to the second conductive connector 7.

Referring to fig. 11, in some embodiments, the conductive assembly 1 may further include 2 or more sequentially disposed second conductive connectors 7, the first conductive connector 5 and the plurality of second conductive connectors 7 are sequentially disposed along the first direction X at the peripheral edge of the electrochromic device 1000, and the first conductive connector 5 and the plurality of second conductive connectors 7 are sequentially stacked and connected.

As can be appreciated, the conductive component 1 is provided with the plurality of second conductive connectors 7, so that the length of the conductive component 1 in the first direction X can be longer to be laid, the conductive area formed is larger, and the color changing speed of the electrochromic device 1000 can be accelerated.

Referring to fig. 9, 10, in some embodiments, adjacent first conductive connection 5 and second conductive connection 7 are spaced apart,

In the first groove 601, the first conductive connection piece 5 forms insulation with the first conductive base layer 2 through the insulation part 5021, and the second conductive connection piece 7 forms electrical connection with the second conductive base layer 4; and/or the number of the groups of groups,

in the second groove 602, the first conductive connection member 5 is insulated from the second conductive base layer 4 by the insulation portion 5021, and the second conductive connection member 7 is electrically connected to the first conductive base layer 2.

Specifically, in some embodiments, the first conductive connecting element 5 may be spaced from the second conductive connecting element 7, and the second conductive connecting element 7 alone forms an electrical connection with the first conductive base layer 2 or the second conductive base layer 4, so that the first conductive connecting element 5 and the second conductive connecting element 7 do not interfere with each other when they are connected to the electrochromic device 1000, and the conductive assembly 1 is more convenient to be arranged. Referring to fig. 11, in some embodiments, the conductive assembly 1 further includes a sealing member 9, and the sealing member 9 is disposed between two adjacent first conductive connecting members 5 and the second conductive connecting member 7. And/or the number of the groups of groups,

the conductive component 1 comprises two or more second conductive connecting pieces 7, wherein two adjacent second conductive connecting pieces 7 are spaced, and a sealing piece 9 is arranged between the two adjacent second conductive connecting pieces 7.

It can be understood that, when the adjacent first conductive connecting piece 5 and the adjacent second conductive connecting pieces 7 are spaced apart from each other, in order to improve the connection stability and the tightness of the conductive assembly 1, the sealing member 9 is disposed at the spacing between the adjacent first conductive connecting piece 5 and the adjacent second conductive connecting piece 7, and at the spacing between the adjacent two second conductive connecting pieces 7, so as to ensure that the bonding structure of the conductive assembly 1 is stable.

Referring to fig. 7-11, in some embodiments, in the first groove 601, the maximum thickness of the conductive assembly 1 is less than or equal to the lamination thickness of the first conductive base layer 2 and the electrochromic layer 3 in the lamination direction Y; and/or the number of the groups of groups,

in the second groove 602, the maximum thickness of the conductive member 1 is smaller than or equal to the lamination thickness of the second conductive base layer 4 and the electrochromic layer 3 in the lamination direction Y.

Specifically, the thickness of the conductive component 1 is the maximum thickness of the whole conductive component 1, and may be only the thickness of the first conductive connecting member 5; it may be the maximum lamination thickness of the two first conductive connectors 5 and the second conductive connectors 7 laminated; or, the maximum lamination thickness of the two laminated second conductive connectors 7; the maximum thickness is not limited herein.

Since the electrochromic device 1000 subsequently needs to perform a lamination operation on the product, in the first groove 601, the conductive assembly 1 as a whole is not higher than the first conductive base layer 2 in the lamination direction Y; in the second groove 602, the conductive member 1 as a whole is not higher than the second conductive base layer 4 in the lamination direction Y; the stress to which the conductive member 1 in the first recess 601 or the second recess 602 is subjected can be not excessively high, and structural stability can be improved.

Referring to fig. 3 and 6, in some embodiments, both ends of the conductive member 1 in the first direction X are disposed on the first conductive base layer 2 outside the first groove 601, and/or both ends of the conductive member 1 in the first direction X are disposed on the second conductive base layer 4 outside the first groove 601.

The other side of the conductive component 1 is partially positioned in the second groove 602 and partially positioned outside the second groove 602; the two ends of the conductive component 1 positioned in the second groove 602 simultaneously cover the first conductive substrate layer 2 and the second conductive substrate layer 4, and the two ends of the conductive component 1 positioned outside the second groove 602 are both arranged at the peripheral edge of one side of the second conductive substrate layer 4 away from the electrochromic layer 3; here, the two ends of the conductive component 1 are two ends of the conductive component 1 in the first direction X.

Referring to fig. 7-11, in some embodiments, the device further comprises an extraction electrode 8, the extraction electrode 8 being electrically connected to the second conductive base layer 4 by the first conductive connection 5 and/or the second conductive connection 7; and/or the number of the groups of groups,

the extraction electrode 8 is electrically connected to the first conductive base layer 2 via the first conductive connection 5 and/or the second conductive connection 7.

It will be appreciated that by providing the extraction electrode 8 on the first conductive connection 5 and/or the second conductive connection 7, the electrochromic device 1000 can be conveniently connected to an external power source.

In some embodiments, referring to fig. 6 and 8, the extraction electrode 8 may be disposed only on the conductive layer 501 of the first conductive connection 5, the extraction electrode 8 being electrically connected to the first conductive base layer 2 through the first conductive connection 5, or the extraction electrode 8 being electrically connected to the second conductive base layer 4 through the first conductive connection 5.

In other embodiments, referring to fig. 7, 8 and 10, the extraction electrode 8 may be disposed only on the second conductive layer 701 of the second conductive connection member 7, where the extraction electrode 8 is electrically connected to the first conductive base layer 2 through the second conductive connection member 7, or where the extraction electrode 8 is electrically connected to the second conductive base layer 4 through the second conductive connection member 7.

In other embodiments, referring to fig. 11, the extraction electrode 8 may be disposed only under the second adhesive layer 702 of the second conductive connecting member 7, so as to avoid the extraction electrode 8 from falling off from the first conductive base layer 2 or the second conductive base layer 4, and further improve the connection stability of the extraction electrode 8.

In still other embodiments, referring to fig. 9, the extraction electrode 8 may also cover both the first conductive connection 5 and the second conductive connection 7.

As can be appreciated, the extraction electrode 8 is provided on the conductive member 1 on the side of the electrochromic device 1000 in the lamination direction Y to form an electrical connection with the second conductive base layer 4;

in other embodiments, an extraction electrode 8 is provided on the conductive assembly 1 on the other side of the electrochromic device 1000 in the lamination direction Y to form an electrical connection with the first conductive base layer 2;

in the above embodiment, the extraction electrodes 8 located at both sides of the stacking direction Y of the electrochromic device are respectively used as the positive electrode or the negative electrode of the electrochromic device 1000, and are electrically connected to an external power source through the extraction electrodes 8 at both sides, thereby realizing the voltage supply to the electrochromic layer. And the extraction electrodes 8 on two sides are always spaced in the stacking direction Y, so that the phenomenon that the electrochromic device 1000 is short-circuited due to the contact of the extraction electrodes 8 on two sides is avoided, and the stability of the electrochromic device 1000 is improved.

In some embodiments, when the extraction electrode 8 is disposed on the first conductive connection member 5, the extraction electrode 8 is disposed on a side of the conductive layer 501 of the first conductive connection member 5 away from the adhesive layer 502, and the extraction electrode 8 is electrically connected to the first conductive base layer 2 through the conductive portion 5022 of the first conductive connection member 5; and/or the number of the groups of groups,

the extraction electrode 8 is disposed on a side of the conductive layer 501 of the first conductive connection member 5 away from the adhesive layer 502, and the extraction electrode 8 is electrically connected to the second conductive base layer 4 through the conductive portion 5022 of the first conductive connection member 5.

It will be appreciated that the extraction electrode 8 needs to be disposed on the side of the conductive layer 501 away from the adhesive layer 502, and cannot be disposed on the side of the conductive layer 501 close to the adhesive layer 502, so as to avoid affecting the connection stability between the first conductive connecting piece 5 and the first conductive base layer 2 or the second conductive base layer 4, and ensure that the first conductive connecting piece 5 can form an effective seal against the side surface of the electrochromic layer 3.

In some embodiments, referring to fig. 7, the extraction electrode 8 is disposed on at least one side of the second conductive connection 7 in the lamination direction Y; the extraction electrode 8 is electrically connected with the first conductive basal layer 2 through the second conductive connecting piece 7; and/or the extraction electrode 8 is electrically connected with the second conductive base layer 4 through the second conductive connection 7.

As can be understood, referring to fig. 10 and 11, when the extraction electrode 8 is provided on the second conductive connection member 7 alone, since both the second conductive layer 701 and the second adhesive layer 702 of the second conductive connection member 7 have conductivity, the extraction electrode 8 can be provided on either side of the second conductive connection member 7 in the lamination direction Y, and the electrochromic device 1000 can be supplied with power through the extraction electrode 8; since the second adhesive layer 702 is conductive as a whole, the extraction electrode 8 is provided on the second connector 7, and the conductivity is higher.

By adopting the above technical scheme, the second bonding layer 702 of the second conductive connecting piece 7 only has a conductive portion, so that when only has a conductive portion, the larger the area of the conductive portion is, when the extraction electrode passes through the second connecting piece 7, the more the area of the conductive portion is, the smaller the resistance value is, and the higher the conductive efficiency is.

Referring to fig. 13, a second aspect of the embodiments of the present application provides an electrochromic device 2000 comprising a substrate 2001, the substrate 2001 being arranged on a side of the first conductive base layer 2 facing away from the electrochromic layer 3; and/or the substrate 2001 is arranged on the side of the second conductive base layer 4 facing away from the electrochromic layer 3.
