[0009] According to the electrochromic film of the embodiment of the present application, by making the first transparent conductive layer of the electrochromic film include a plurality of sub-transparent conductive parts arranged at intervals along the surface of the first substrate layer and / or the second transparent conductive layer include a plurality of sub-transparent conductive parts arranged at intervals along the surface of the second substrate layer, the plurality of sub-transparent conductive parts can be independently controlled, so that the parts corresponding to the plurality of sub-transparent conductive parts on the electrochromic film show different transparency or color changes, and the parts corresponding to the sub-transparent conductive parts can be combined to form patterns or text, so that the display content of the electrochromic film is richer and can be applied to more scenarios.

[0010] According to some embodiments of the present application, the plurality of sub-transparent conductive portions on the first substrate layer are arranged in an array.

For example, the pattern layer can be a predetermined texture or image. By locating the pattern layer on the side of the second film layer away from the ion layer, users can see the pattern on the pattern layer through the electrochromic layer.

[0033] According to some embodiments of the present application, the substrate skeleton is a transparent member, and the electrochromic decorative member further includes a backlight layer, which is located on a side of the substrate skeleton facing away from the electrochromic film.

[0034] In the above-mentioned technical solution, by including a backlight layer in the electrochromic decorative piece and making the base frame transparent, users can see the light emitted by the backlight layer through the base frame, thereby enhancing the functionality of the electrochromic decorative piece. For example, at night or in low-light conditions, the backlight layer can be illuminated, allowing users to more clearly see the content displayed on the electrochromic decorative piece.

[0035] According to some embodiments of the present application, the transparency of the substrate skeleton is ≥90%.

[0036] In the above technical solution, by making the transparency of the substrate skeleton ≥90%, the light transmittance of the substrate skeleton can be improved, and relevant personnel can more easily see the light emitted by the backlight panel through the substrate skeleton.

[0044] According to the control method of the electrochromic decorative part of the embodiment of the present application, by making the electrochromic module chip calculate the voltage parameters of each sub-transparent conductive part according to the color change instruction received by the driving module chip, and then making the driving module chip apply the corresponding voltage to each sub-transparent conductive part, the voltage of multiple sub-transparent conductive parts can be controlled separately, thereby controlling the color or transparency of the electrochromic decorative part parts corresponding to the multiple sub-transparent conductive parts separately, so that the electrochromic decorative part can display the set pattern.

[0045] According to some embodiments of the present application, before applying a corresponding voltage to each of the sub-transparent conductive portions, the driving module chip identifies the coordinates of each of the sub-transparent conductive portions.

[0046] In the above technical solution, the driving module chip identifies the coordinates of each sub-transparent conductive portion before applying the corresponding voltage to each sub-transparent conductive portion. This allows the driving module chip to identify the position of each sub-transparent conductive portion, so that the driving module chip can calculate the voltage applied to each sub-transparent conductive portion.

[0047] According to some embodiments of the present application, the driving module chip identifies the coordinates of each of the sub-transparent conductive portions, including: identifying the row number and column number of each of the sub-transparent conductive portions.

[0048] In the above technical solution, by enabling the driving module chip to identify the row and column number of each sub-transparent conductive portion, the position of the sub-transparent conductive portion is converted to a row and column number that is easier to be identified by the driving module chip, which makes it easier for the driving module chip to distinguish the position of each sub-transparent conductive portion, thereby making it easier for the driving module chip to calculate the voltage required for each sub-transparent conductive portion.

[0049] According to some embodiments of the present application, the color change instruction includes: controlling the voltage parameter of a single sub-transparent conductive portion to change linearly.

[0050] In the above technical solution, by making the voltage parameter of a single sub-transparent conductive portion change linearly and gradually changing the voltage parameter, compared with making the voltage parameter change between several set values, the transparency or color displayed by the electrochromic decorative part at the corresponding position of each sub-transparent conductive portion can have more forms, making the transparency or color displayed by the electrochromic decorative part richer.

[0052] In the above technical solution, by making the color change instruction include synchronous development, the electrochromic decorative parts at corresponding positions of multiple sub-transparent conductive parts can change transparency or color synchronously, which can meet users' more demands for electrochromic decorative parts and enhance the interactive ability of electrochromic decorative parts; by applying the same initial voltage to each sub-transparent conductive part at the same time when the color change instruction is synchronous development, the voltage applied to each sub-transparent conductive part changes according to the same preset change rate, so that at the same time, each sub-transparent conductive part is subjected to the same voltage, so that the electrochromic decorative part as a whole presents the same transparency or color.

[0053] According to some embodiments of the present application, the plurality of sub-transparent conductive portions are divided into a plurality of groups, each group including at least one sub-transparent conductive portion, and the color change instruction includes a gradient development, and the gradient development includes: the voltages applied to the sub-transparent conductive portions in the same group are the same, and the voltages applied to multiple groups of sub-transparent conductive portions at the same time are different.

[0054] In the above technical solution, by making the color change instruction include gradual development, the transparency or color of the electrochromic decorative parts corresponding to the sub-transparent conductive parts of different groups can be different at the same time, which can meet the user's more needs for electrochromic decorative parts and enhance the interactive ability of the electrochromic decorative parts; by applying the same voltage to the sub-transparent conductive parts in the same group when the color change instruction is gradual development, and applying different voltages to multiple groups of sub-transparent conductive parts at the same time, the electrochromic decorative parts corresponding to the sub-transparent conductive parts in the same group at the same time can be made to present the same transparency or color, while the electrochromic decorative parts corresponding to the sub-transparent conductive parts in different groups at the same time can present different transparency or colors.

[0055] According to some embodiments of the present application, the voltages applied to the multiple groups of sub-transparent conductive portions at the same time are different, including: according to the arrangement order of the multiple groups of sub-transparent conductive portions, the voltages applied to the multiple groups of sub-transparent conductive portions at the same time are increased or decreased in sequence.

[0056] In the above technical solution, by increasing or decreasing the voltage applied to multiple groups of sub-transparent conductive parts at the same time in sequence, the transparency or color of the electrochromic decorative parts at the same time can present a gradient effect, which can meet users' more demands for electrochromic decorative parts and enhance the interactive ability of electrochromic decorative parts.

[0057] According to some embodiments of the present application, according to the arrangement order of the multiple groups of sub-transparent conductive portions, the voltages applied to the multiple groups of sub-transparent conductive portions at the same time are increased or decreased in sequence, including: according to the arrangement order of the multiple groups of sub-transparent conductive portions, the same initial voltage is applied to each group of the sub-transparent conductive portions in sequence; the voltage applied to each group of the sub-transparent conductive portions changes according to the same preset change rate.

[0059] According to some embodiments of the present application, the time interval between applying voltages between two adjacent groups of sub-transparent conductive portions is 0.1s-0.5s.

[0060] In the above technical solution, by setting the time interval between the voltage application of two adjacent groups of the sub-transparent conductive parts to 0.1s-0.5s, the relevant users can more clearly experience the gradual change effect presented by the electrochromic decorative piece.

[0061] According to some embodiments of the present application, multiple groups of the sub-transparent conductive portions are arranged side by side; or, multiple groups of the sub-transparent conductive portions are arranged in sequence from the center of the electrochromic film to the outer edge of the electrochromic film.

[0062] In the above technical solution, by arranging multiple groups of sub-transparent conductive portions side by side, the electrochromic decorative piece can present a gradient effect along the direction in which the sub-transparent conductive portions are arranged side by side. For example, if multiple groups of sub-transparent conductive portions are arranged side by side in the left-right direction, the electrochromic decorative piece can present a gradient effect in the left-right direction; for another example, if multiple groups of sub-transparent conductive portions are arranged side by side in the up-down direction, the electrochromic decorative piece can present a gradient effect in the up-down direction. By arranging multiple groups of sub-transparent conductive portions in sequence from the center of the electrochromic film to the outer edge of the electrochromic film, the electrochromic decorative piece can present a gradient effect radiating from the center. For example, the electrochromic decorative piece can present a gradient effect radiating from the center to the outside, or it can present a gradient effect radiating from the periphery to the center.

[0065] According to some embodiments of the present application, the control module receives a color change instruction, including: the color change instruction received by the control module is sent to the control module by at least one of an ambient light sensor, an atmosphere light, a mobile phone APP program, and a seat status detection module.

[0066] In the above technical solution, by enabling the control module to receive the color change instructions sent to the control module by at least one of the ambient light sensor, atmosphere light, mobile phone APP program and seat status detection module, the control module can control the color or transparency of the electrochromic film to change according to the scene or the needs of relevant personnel, thereby improving the interactive ability of the electrochromic decorative parts.

[0067] According to the preparation method of the electrochromic film according to the fifth embodiment of the present application, it is characterized in that the electrochromic film is the electrochromic film according to the first embodiment of the present application, and the preparation method of the electrochromic film includes: preparing a first film blank having a transparent conductive layer; etching the transparent conductive layer of the first film blank using an etching process to form a plurality of spaced-apart sub-transparent conductive portions; processing the etched first film blank into a preset shape to form the first film layer; forming the ion layer on the transparent conductive layer side of the first film layer; preparing the second film layer; and laminating the second film layer and the first film layer formed with the ion layer to form the electrochromic film.

[0068] According to the preparation method of the electrochromic film of the embodiment of the present application, by adopting the etching process, the transparent conductive layer of the first film blank can be conveniently etched to form a plurality of spaced-apart sub-transparent conductive parts. Under the condition that the area of ​​the transparent conductive layer is constant, a large number of sub-transparent conductive parts can be etched out through the etching process, and the size of the sub-transparent conductive parts can also be made smaller. In this way, the control of the plurality of sub-transparent conductive parts of the first film layer can be more subtle, and by separately controlling the transparency or color change of each sub-transparent conductive part, richer and more diverse display content can be presented.

[0069] According to some embodiments of the present application, forming the first film blank after etching into a preset shape includes: performing vacuum molding on the first film blank after etching.

[0070] In the above technical solution, by subjecting the etched first film blank to vacuum molding, the etched first film blank can not only present a planar state, but also a three-dimensional shape, and can present a corresponding shape according to needs, so that the electrochromic film can be set on a curved surface, making the application range of the electrochromic film wider.

[0071] According to some embodiments of the present application, forming the ion layer on the transparent conductive layer side of the first film layer includes: forming the ion layer on the transparent conductive layer side of the first film layer using an inkjet printing process.

[0072] In the above technical solution, since the first film layer may be in a curved shape, an ion layer is formed on the conductive layer side of the first film layer by using an inkjet printing process. Compared with the coating method in the related art, the formed ion layer is more evenly distributed.

[0073] According to some embodiments of the present application, preparing the second film layer includes: forming the second substrate layer using a vacuum forming process; and evaporating the second transparent conductive layer on the second substrate layer to form the second film layer.

[0074] In the above technical solution, the second substrate layer is formed by adopting the vacuum forming process, so that the second substrate layer can not only present a planar state, but also present a three-dimensional shape, and can present a corresponding shape according to needs, so that the electrochromic film can be set on a curved surface, making the application range of the electrochromic film wider; since the second substrate layer may be a curved surface, the second conductive layer is evaporated on the second substrate layer to form the second film layer. Compared with the coating method in the related art, the second conductive layer formed is more evenly distributed.

[0079] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0080] Reference below Figures 1-9 The electrochromic film 101 according to an embodiment of the present application is described.

[0081] Reference Figure 1-Figure 2 According to the first embodiment of the present application, an electrochromic film 101 includes: an ion layer 2, a first film layer 1 and a second film layer 3.

[0082] The ion layer 2 includes an electrochromic layer 23, and the first film layer 1 and the second film layer 3 are arranged on opposite sides of the ion layer 2 in the thickness direction. The first film layer 1 includes a first substrate layer 11 and a first transparent conductive layer 12. The first transparent conductive layer 12 is located on the side of the first substrate layer 11 close to the ion layer 2. The second film layer 3 includes a second substrate layer 31 and a second transparent conductive layer 32. The second transparent conductive layer 32 is located on the side of the second substrate layer 31 close to the ion layer 2. The first transparent conductive layer 12 includes a plurality of sub-transparent conductive portions 121 arranged at intervals along the surface of the first substrate layer 11 and / or the second transparent conductive layer 32 includes a plurality of sub-transparent conductive portions 121 arranged at intervals along the surface of the second substrate layer 31.

[0083] For example, the ion layer 2 includes an ion storage layer 21, an ion transport layer 22, and an electrochromic layer 23. The ion transport layer 22 is located between the ion storage layer 21 and the electrochromic layer 23, the ion storage layer 21 is located on the side of the ion transport layer 22 close to the first membrane layer 1, and the electrochromic layer 23 is located on the side of the ion transport layer 22 close to the second membrane layer 3.

[0084] For example, the electrochromic layer 23 can change transparency or color according to the voltage between the first transparent conductive layer 12 and the second transparent conductive layer 32, thereby realizing the development or hiding effect of the dynamic effect of the electrochromic film 101 and enhancing the interaction ability between the electrochromic film 101 and relevant personnel.

[0085] Reference Figure 5 and Figure 6 When the first transparent conductive layer 12 includes a plurality of sub-transparent conductive portions 121 spaced apart along the surface of the first substrate layer 11, the electrochromic layer 23 corresponding to each sub-transparent conductive portion 121 can change transparency or color based on the voltage between the sub-transparent conductive portion 121 and the second transparent conductive layer 32, causing the corresponding position of the electrochromic film 101 to exhibit a change in transparency or color. When the second transparent conductive layer 32 includes a plurality of sub-transparent conductive portions 121 spaced apart along the surface of the second substrate layer 31, the electrochromic layer 23 corresponding to each sub-transparent conductive portion 121 can change transparency or color based on the voltage between the sub-transparent conductive portion 121 and the first transparent conductive layer 12, causing the corresponding position of the electrochromic film 101 to exhibit a change in transparency or color. The electrochromic film 101 at the corresponding positions of the plurality of sub-transparent conductive portions 121 can exhibit different transparency or color changes. Under a set combination, a set pattern or text can be displayed to meet the display needs of relevant personnel, without the need to add additional accessories to display the set pattern or text as in the related art.

[0086] When the relevant personnel need to change the displayed pattern or text, they can change the transparency or color of the electrochromic film 101 at the corresponding position of the different sub-transparent conductive parts 121 to make the electrochromic film 101 show the changed pattern or text. It is more convenient to change these patterns or texts.

[0087] According to the electrochromic film 101 of the embodiment of the present application, by making the ion layer 2 of the electrochromic film 101 include the electrochromic layer 23, the electrochromic layer 23 can make the transparency or color of the electrochromic film 101 show dynamic changes, realize the development or hiding effect of the dynamic effect of the electrochromic film 101, and enhance the interaction ability between the electrochromic film 101 and relevant personnel; by making the first transparent conductive layer 12 of the electrochromic film 101 include a plurality of sub-transparent conductive parts 12 arranged at intervals along the surface of the first substrate layer 11 1 and / or the second transparent conductive layer 32 includes a plurality of sub-transparent conductive portions 121 spaced apart along the surface of the second substrate layer 31. The plurality of sub-transparent conductive portions 121 can independently change from being energized to being energized or changing the voltage, so that the portions corresponding to the plurality of sub-transparent conductive portions 121 on the electrochromic film 101 exhibit different transparency or color changes. The portions corresponding to the sub-transparent conductive portions 121 can be combined to form special patterns or texts without the need for additional accessories, and it is more convenient to change these patterns or texts.

[0093] In the above technical solution, by making the electrochromic film 101 also include an appearance protection layer 41, and making the appearance protection layer 41 be arranged on the side of the first film layer 1 away from the ion layer 2, the appearance protection layer 41 can play a role in protecting the first film layer 1, preventing external dust or water from falling onto the first film layer 1 and causing the first film layer 1 to be worn or damaged.

[0094] Reference Figure 1 According to some embodiments of the present application, the first transparent conductive layer 12 includes a plurality of sub-transparent conductive portions 121 arranged at intervals along the surface of the first substrate layer 11 .

[0097] In the above technical solution, by including a pattern layer 42 in the electrochromic film 101, the pattern presented by the electrochromic film 101 can be enriched. For example, the pattern layer 42 can be a predetermined texture or picture. By positioning the pattern layer 42 on the side of the second film layer 3 away from the ion layer 2, users can see the pattern on the pattern layer 42 through the electrochromic layer 23. When the transparency of the electrochromic layer 23 changes, the pattern seen by users can change, thereby enhancing the interactive capabilities of the electrochromic film 101. For example, when the transparency of the electrochromic layer 23 decreases, the pattern is hidden; when the transparency of the electrochromic layer 23 increases, the pattern becomes visible.

Each sub-transparent conductive portion 121 is electrically connected to the driving module chip, and the driving module chip is used to receive a color change instruction and control the voltage parameters of each sub-transparent conductive portion 121 according to the received color change instruction. Each sub-transparent conductive portion 121 is electrically connected to the electrochromic module chip, and the electrochromic module chip is electrically connected to the driving module chip. The electrochromic module chip is used to calculate the voltage parameters of each sub-transparent conductive portion 121 according to the color change instruction received by the driving module chip.

[0102] Reference Figure 3 According to some embodiments of the present application, the electrochromic decorative component 100 further includes a substrate skeleton 6 , and the substrate skeleton 6 is located on one side of the second substrate layer 31 of the electrochromic film 101 .

[0103] In the above technical solution, the electrochromic decorative component 100 further includes a substrate skeleton 6 , which can provide support for the electrochromic film 101 , thereby preventing the electrochromic film 101 from being deformed and causing a reduction in or damage to the display effect.

[0104] For example, the preformed electrochromic film 101 is placed in the mold cavity of the substrate skeleton 6 in advance. When the substrate skeleton 6 is injection molded, the substrate skeleton 6 and the surface of the electrochromic film 101 are fused together, so that the electrochromic film 101 covers the surface of the substrate skeleton 6, and after cooling, the electrochromic decorative part 100 is formed.

[0105] For example, the skeleton can be made of transparent material or non-transparent material. When the skeleton is made of non-transparent material, ABS or PC+ABS can be selected; when the skeleton is made of transparent material, PC substrate can be selected.

[0106] According to some embodiments of the present application, the thickness of the substrate skeleton 6 is d2, 2.5 mm ≤ d2 ≤ 3 mm.

[0107] For example, the value of d2 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, etc.

[0108] In the above technical solution, by making the thickness d2 of the substrate skeleton 6 not less than 2.5 mm, the substrate skeleton 6 can have sufficient strength to avoid deformation and damage of the electrochromic decorative part 100; by making the thickness d2 of the substrate skeleton 6 not greater than 3 mm, it is possible to ensure that the substrate skeleton 6 has sufficient strength while avoiding the substrate skeleton 6 being too thick, which makes the electrochromic decorative part 100 as a whole too thick and occupies more space.

[0109] Reference Figure 3 According to some embodiments of the present application, the electrochromic decorative component 100 further includes an adhesive layer 5 , which is located between the substrate skeleton 6 and the electrochromic film 101 .

[0110] For example, the adhesive layer 5 may be an OCA optical adhesive, which is a double-sided laminating pressure-sensitive adhesive without a substrate.

[0112] Reference Figure 3 According to some embodiments of the present application, the thickness of the adhesion layer 5 is d1, 25 μm≤d1≤250 μm.

[0113] For example, the value of d1 can be 25 μm, 30 μm, 50 μm, 80 μm, 100 μm, 150 μm, 200 μm, 250 μm, etc.

[0114] In the above technical solution, by making the thickness d1 of the adhesive layer 5 not less than 25 μm, the fixing and adhering effect of the adhesive layer 5 on the substrate skeleton 6 and the electrochromic film 101 can be made more reliable, and the electrochromic film 101 can be more effectively prevented from falling off from the substrate skeleton 6; by making the thickness d1 of the adhesive layer 5 not greater than 250 μm, it can ensure that the adhesive layer 5 has a sufficient fixing and adhering effect on the substrate skeleton 6 and the electrochromic film 101, while avoiding the adhesive layer 5 being too thick, which makes the overall electrochromic decorative part 100 too thick and occupies more space.

[0115] Reference Figure 3 According to some embodiments of the present application, the substrate skeleton 6 is a transparent member, and the electrochromic decorative member 100 further includes a backlight layer 7 , which is located on a side of the substrate skeleton 6 away from the electrochromic film 101 .

[0116] For example, the backlight layer 7 can emit light of different wavelength spectrum bands, and the backlight layer 7 is integrated with the electrochromic film 101 to form an ambient light effect.

[0117] In the above-described technical solution, by including a backlight layer 7 in the electrochromic decorative piece 100 and making the base frame 6 transparent, users can see the light emitted by the backlight layer 7 through the base frame 6, thereby enhancing the functionality of the electrochromic decorative piece 100. For example, at night or in low-light conditions, the backlight layer 7 can be illuminated, allowing users to more clearly see the content displayed on the electrochromic decorative piece 100.

[0118] According to some embodiments of the present application, the transparency of the substrate skeleton 6 is ≥90%.

[0119] For example, the transparency of the base skeleton 6 may be 90%, 92%, 94%, 95%, 96%, 98%, 100%, etc.

[0120] In the above technical solution, by making the transparency of the substrate skeleton 6 ≥90%, the light transmittance of the substrate skeleton 6 can be improved, and relevant personnel can more easily see the light emitted by the backlight panel through the substrate skeleton 6.

[0121] Reference Figure 3 According to some embodiments of the present application, the electrochromic decorative component 100 further includes an adhesive layer 5 , which is located between the substrate skeleton 6 and the electrochromic film 101 , and the transparency of the adhesive layer 5 is ≥90%, and the haze of the adhesive layer 5 is ≤1.0%.

[0122] For example, the transparency of the adhesive layer 5 may be 90%, 92%, 94%, 95%, 96%, 98%, 100%, etc.; the haze of the adhesive layer 5 may be 1.0%, 0.8%, 0.6%, 0.4%, 0.2%, etc.

[0123] In the above technical solution, by making the electrochromic decorative part 100 also include an adhesive layer 5, the connection between the substrate skeleton 6 and the electrochromic film 101 can be made tighter, thereby preventing the electrochromic film 101 from falling off the substrate skeleton 6; by making the transparency of the adhesive layer 5 ≥90% and the haze ≤1.0%, the light transmittance of the adhesive layer 5 can be made better, and relevant personnel can more easily see the light emitted by the backlight panel through the adhesive layer 5.

[0125] According to the vehicle of the embodiment of the present application, by including the electrochromic decorative part 100 according to the embodiment of the second aspect of the present application, the electrochromic decorative part 100 can be combined to form special patterns or texts without the need for additional accessories, and it is more convenient to change these patterns or texts.

[0126] According to some embodiments of the present application, the electrochromic decorative component 100 is installed in the interior of a vehicle.

[0127] In the above technical solution, by installing the electrochromic decorative element 100 in the vehicle interior, the interaction between the vehicle interior and relevant personnel inside the vehicle can be improved, thereby enhancing the functionality of the vehicle interior.

[0128] Reference Figure 4 According to a control method of an electrochromic decorative element 100 according to a fourth embodiment of the present application, the electrochromic decorative element 100 is the electrochromic decorative element 100 according to the second embodiment of the present application. The control method of the electrochromic decorative element 100 includes: The control module receives a color change instruction; The control module sends the received color change instruction to the drive module chip; The electrochromic module chip calculates the voltage parameters of each sub-transparent conductive portion 121 according to the color change instruction received by the driving module chip; The driving module chip applies a corresponding voltage to each sub-transparent conductive portion 121 according to the voltage parameter of each sub-transparent conductive portion 121 calculated by the electrochromic module chip.

[0129] For example, the electrochromic film 101 is powered by a programmable power supply. The programmable power supply is used to generate the required driving voltage, which can be set within a range of ±0.1V-300V. The electrochromic module chip, based on the input required instructions, distributes different positive and negative voltage values ​​and applies them to different sub-transparent conductive portions 121, thereby achieving color or transparency changes in different sub-transparent conductive portions 121.

[0130] For example, the control module can also be powered by a programmable power supply.

[0131] According to the control method of the electrochromic decorative part 100 of the embodiment of the present application, by making the electrochromic module chip calculate the voltage parameters of each sub-transparent conductive part 121 according to the color change instruction received by the driving module chip, and then making the driving module chip apply corresponding voltages to each sub-transparent conductive part 121, the voltages of multiple sub-transparent conductive parts 121 can be controlled separately, thereby controlling the colors or transparency of the parts of the electrochromic decorative part 100 corresponding to the multiple sub-transparent conductive parts 121 separately, so that the electrochromic decorative part 100 can display the set pattern.

[0132] According to some embodiments of the present application, before applying a corresponding voltage to each sub-transparent conductive portion 121 , the process includes: a driving module chip identifying the coordinates of each sub-transparent conductive portion 121 .

[0133] In the above technical solution, before applying the corresponding voltage to each sub-transparent conductive portion 121, the driving module chip first identifies the coordinates of each sub-transparent conductive portion 121, so that the driving module chip can identify the position of each sub-transparent conductive portion 121, so that the driving module chip can calculate the voltage applied to each sub-transparent conductive portion 121.

[0134] According to some embodiments of the present application, the driving module chip identifies the coordinates of each sub-transparent conductive portion 121 , including: identifying the row number and column number of each sub-transparent conductive portion 121 .

[0135] For example, the multiple sub-transparent conductive portions 121 are numbered from left to right as column 1 to column m, and from top to bottom as row 1 to row s. The position coordinates of each sub-transparent conductive portion 121 in the electrochromic film 101 can be determined by the intersection value of the rows and columns. For example, the sub-transparent conductive portion 121 located in the leftmost column and the topmost row of all sub-transparent conductive portions 121 is located in column 1 and row 1. The driving module can identify the row and column number of each sub-transparent conductive portion 121.

[0136] In the above technical solution, by enabling the driving module chip to identify the row and column number of each sub-transparent conductive portion 121, the position of the sub-transparent conductive portion 121 is converted to a row and column number that is easier to be identified by the driving module chip. This makes it easier for the driving module chip to distinguish the position of each sub-transparent conductive portion 121, thereby making it easier for the driving module chip to calculate the voltage required for each sub-transparent conductive portion 121.

[0137] Reference Figure 7 According to some embodiments of the present application, the color change instruction includes: controlling the voltage parameter of a single sub-transparent conductive portion 121 to change linearly.

[0138] For example, the voltage parameter of a single sub-transparent conductive portion 121 can be controlled to change linearly from -15V to 15V.

[0139] In the above technical solution, by making the voltage parameter of a single sub-transparent conductive portion 121 change linearly and gradually changing the voltage parameter, compared with making the voltage parameter change between several set values, the transparency or color displayed by the electrochromic decorative part 100 at the corresponding position of each sub-transparent conductive portion 121 can have more forms, making the transparency or color displayed by the electrochromic decorative part 100 richer.

[0140] Reference Figure 7According to some embodiments of the present application, the color change instruction includes synchronous development, and the synchronous development includes: applying the same initial voltage to each sub-transparent conductive portion 121 at the same time; and changing the voltage applied to each sub-transparent conductive portion 121 according to the same preset change rate.

[0141] For example, Figure 7 From left to right in the middle, the voltage applied to each sub-transparent conductive portion 121 changes at the same preset change rate, so that the electrochromic decorative element 100 as a whole presents the same transparency and the transparency changes synchronously.

[0142] In the above technical solution, by making the color change instruction include synchronous development, the electrochromic decorative part 100 at the corresponding positions of multiple sub-transparent conductive parts 121 can change transparency or color synchronously, which can meet the user's more needs for the electrochromic decorative part 100 and enhance the interactive ability of the electrochromic decorative part 100; by applying the same initial voltage to each sub-transparent conductive part 121 at the same time when the color change instruction is synchronous development, the voltage applied to each sub-transparent conductive part 121 changes according to the same preset change rate, so that at the same time, each sub-transparent conductive part 121 is subjected to the same voltage, so that the electrochromic decorative part 100 as a whole presents the same transparency or color.

[0143] According to some embodiments of the present application, multiple sub-transparent conductive portions 121 are divided into multiple groups, each group includes at least one sub-transparent conductive portion 121, and the color change instruction includes gradient development. The gradient development includes: the voltages applied to the sub-transparent conductive portions 121 in the same group are the same, and the voltages applied to multiple groups of sub-transparent conductive portions 121 at the same time are different.

[0144] For example, in the initial state, all the sub-transparent conductive parts 121 are in an opaque state, and the driving module drives the electrochromic module chip to apply voltage from the sub-transparent conductive parts 121 of the first column, and the voltage value changes according to the set change rate; after the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 of the first group for a set time, the electrochromic module chip applies voltage from the sub-transparent conductive parts 121 of the second group, and also changes the voltage value according to the set change rate. After the set time, the electrochromic module chip applies voltage to the third group of sub-transparent conductive parts 121, and finally the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 of the last group, and finally the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 of the last group, so that the electrochromic film 101 forms a gradual development change.

[0145] In the above technical solution, by making the color change instruction include gradual development, the transparency or color of the electrochromic decorative parts 100 at the corresponding positions of the sub-transparent conductive parts 121 of different groups can be different at the same time, which can meet the user's more needs for the electrochromic decorative parts 100 and enhance the interactive ability of the electrochromic decorative parts 100; by applying the same voltage to the sub-transparent conductive parts 121 in the same group when the color change instruction is gradual development, and applying different voltages to multiple groups of sub-transparent conductive parts 121 at the same time, the electrochromic decorative parts 100 corresponding to the sub-transparent conductive parts 121 in the same group at the same time can present the same transparency or color, while the electrochromic decorative parts 100 corresponding to the sub-transparent conductive parts 121 in different groups at the same time can present different transparency or colors.

[0146] According to some embodiments of the present application, different voltages are applied to the multiple groups of sub-transparent conductive portions 121 at the same time, including: according to the arrangement order of the multiple groups of sub-transparent conductive portions 121, the voltages applied to the multiple groups of sub-transparent conductive portions 121 at the same time increase or decrease in sequence.

[0147] In the above technical solution, by increasing or decreasing the voltage applied to multiple groups of sub-transparent conductive parts 121 at the same time in sequence, the transparency or color of the electrochromic decorative part 100 at the same time can present a gradient effect, which can meet the user's more demands for the electrochromic decorative part 100 and enhance the interactive ability of the electrochromic decorative part 100.

[0148] According to some embodiments of the present application, according to the arrangement order of the multiple groups of sub-transparent conductive portions 121, the voltages applied to the multiple groups of sub-transparent conductive portions 121 at the same time are increased or decreased in sequence, including: according to the arrangement order of the multiple groups of sub-transparent conductive portions 121, the same initial voltage is applied to each group of sub-transparent conductive portions 121 in sequence; the voltage applied to each group of sub-transparent conductive portions 121 changes according to the same preset change rate.

[0149] In the above technical solution, by applying the same initial voltage to each group of sub-transparent conductive portions 121 in sequence according to the arrangement order of the multiple groups of sub-transparent conductive portions 121, and the voltage applied to each group of sub-transparent conductive portions 121 changes according to the same preset change rate, the transparency or color gradient effect of the electrochromic decorative part 100 at the same time can be made more stable, which can meet the user's more demands for the electrochromic decorative part 100 and enhance the interactive ability of the electrochromic decorative part 100.

[0150] According to some embodiments of the present application, the time interval between applying voltages to two adjacent groups of sub-transparent conductive portions 121 is 0.1s-0.5s.

[0151] In the above technical solution, by setting the time interval for applying voltage to two adjacent groups of sub-transparent conductive portions 121 to 0.1s-0.5s, users can more clearly experience the gradual change effect of the electrochromic decorative element 100 .

[0152] According to some embodiments of the present application, multiple groups of sub-transparent conductive portions 121 are arranged side by side; or, multiple groups of sub-transparent conductive portions 121 are arranged in sequence from the center of the electrochromic film 101 to the outer edge of the electrochromic film 101 .

[0153] For example, in the initial state, all the sub-transparent conductive parts 121 are in an opaque state, and the driving module drives the electrochromic module chip to apply voltage to the sub-transparent conductive parts 121 in the first column, and the voltage value changes according to a set change rate; after the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 in the first column for a set time, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 in the second column, and also changes the voltage value according to a set change rate. After the set time, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 in the third column, and finally the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 in the last column, and finally the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 in the last column, so that the electrochromic film 101 forms a gradual development change from left to right.

[0154] For example, in the initial state, all sub-transparent conductive parts 121 are in an opaque state, and at least one sub-transparent conductive part 121 in the center of the electrochromic film 101 is defined as the origin. The driving module drives the electrochromic module chip to apply voltage from the origin, and the voltage value changes according to the set change rate; after the electrochromic module chip applies voltage to the origin for a set time, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 around the origin, and also changes the voltage value according to the set change rate. After the set time, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 around the sub-transparent conductive part 121 to which voltage was applied last, and finally the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 in the outermost circle, and finally the electrochromic film 101 forms a gradual development change from the center to the surrounding areas.

[0155] In the above technical solution, by arranging multiple groups of sub-transparent conductive portions 121 side by side, the electrochromic decorative member 100 can present a gradient effect along the direction in which the sub-transparent conductive portions 121 are arranged side by side. For example, if multiple groups of sub-transparent conductive portions 121 are arranged side by side in the left-right direction, the electrochromic decorative member 100 can present a gradient effect in the left-right direction; for another example, if multiple groups of sub-transparent conductive portions 121 are arranged side by side in the top-bottom direction, the electrochromic decorative member 100 can present a gradient effect in the top-bottom direction. By arranging multiple groups of sub-transparent conductive portions 121 in sequence from the center of the electrochromic film 101 to the outer edge of the electrochromic film 101, the electrochromic decorative member 100 can present a center-radiating gradient effect. For example, the electrochromic decorative member 100 can present a gradient effect radiating outward from the center, or a gradient effect radiating from the periphery to the center.

[0156] Reference Figure 8 According to some embodiments of the present application, the color change instruction includes mosaic development, and the mosaic development includes: randomly applying a voltage to each sub-transparent conductive portion 121.

[0157] For example, Figure 8 The left picture shows the state when no color change instruction is received. Figure 8 The right picture in the figure shows the state after receiving the mosaic development and color change instruction, and the electrochromic decorative component 100 presents a mosaic visual effect.

[0158] In the above technical solution, by randomly applying voltage to each sub-transparent conductive portion 121, the electrochromic decorative piece 100 can present a mosaic visual effect, which can meet users' more demands for the electrochromic decorative piece 100 and enhance the interactive capability of the electrochromic decorative piece 100.

[0159] Reference Figure 4 According to some embodiments of the present application, the control module receives a color change instruction, including: the color change instruction received by the control module is sent to the control module by at least one of an ambient light sensor, an atmosphere light, a mobile phone APP program, and a seat status detection module.

[0160] For example, the ambient light sensor includes a sunlight sensor, which detects the external ambient light. When the external ambient light is dark, it is determined to be a night driving scene. The sunlight sensor sends a color change instruction to the control module, and the control module controls the transparency of the electrochromic film 101 to increase.

[0161] For example, the control module receives a color change instruction of the ambient light. When the ambient light changes color, the control module controls the electrochromic film 101 to change color to match the light color of the ambient light.

[0162] For example, relevant personnel transmit the color-changing instruction to the Bluetooth module through the mobile phone APP program, the Bluetooth module sends the color-changing instruction to the control module, and the control module controls the electrochromic film 101 to display the set pattern or text.

[0163] For example, when the seat state detection module detects that the seat is in a lying state, that is, a zero-gravity state, it determines that it is an entertainment mode scene and sends a color change instruction to the control module. The control module controls the transparency of the electrochromic film 101 to increase, so that the electrochromic film 101 becomes translucent, or can make the electrochromic film 101 present a gradient effect.

[0164] In the above technical solution, by enabling the control module to receive the color change instructions sent to the control module by at least one of the ambient light sensor, atmosphere light, mobile phone APP program and seat status detection module, the control module can control the color or transparency of the electrochromic film 101 to change according to the scene or the needs of relevant personnel, thereby improving the interactive ability of the electrochromic decorative part 100.

[0165] Reference Figure 9 According to a method for preparing an electrochromic film 101 according to a fifth embodiment of the present application, the electrochromic film 101 is the electrochromic film 101 according to the first embodiment of the present application, and the method for preparing the electrochromic film 101 includes: preparing a first film blank having a transparent conductive layer; The transparent conductive layer of the first film blank is etched by an etching process to form a plurality of spaced-apart sub-transparent conductive portions 121; Processing and shaping the etched first film blank into a preset shape to form a first film layer 1; An ion layer 2 is formed on the transparent conductive layer side of the first film layer 1; preparing a second film layer 3; The second film layer 3 is laminated with the first film layer 1 having the ion layer 2 formed thereon to form the electrochromic film 101 .

[0166] For example, a chemical etching process may be used to etch the transparent conductive layer of the first film blank to form a plurality of spaced-apart sub-transparent conductive portions 121 .

[0167] For example, the first film blank is an FPC substrate. Processing the etched first film blank into a preset shape may include: softening the first film blank by heating, vacuum forming and stretching the first film blank in the horizontal and vertical directions to form a three-dimensional curved surface shape, and then cutting off the excess peripheral substrate material of the first film blank after forming.

[0168] For example, forming the ion layer 2 on the transparent conductive layer side of the first film layer 1 includes: using liquid raw materials through an inkjet printer to uniformly spray the ion storage layer 21, the ion transport layer and the electrochromic layer 23 onto the first film layer 1 in sequence.

[0169] According to the preparation method of the electrochromic film 101 of the embodiment of the present application, the transparent conductive layer of the first film blank is etched by adopting an etching process to form a plurality of spaced-apart sub-transparent conductive portions 121, so that the plurality of sub-transparent conductive portions 121 can independently change the voltage, so that the portions corresponding to the plurality of sub-transparent conductive portions 121 on the electrochromic film 101 show different transparency or color changes, and the portions corresponding to the sub-transparent conductive portions 121 can be combined to form special patterns or texts without the need for additional accessories, and it is more convenient to change these patterns or texts; by processing the etched first film blank into a preset shape to form the first film layer 1, the first film layer 1 can be set to different shapes according to needs, which can meet more needs of relevant personnel.

[0170] According to some embodiments of the present application, the etched first film blank is processed and formed into a preset shape, including: the etched first film blank is subjected to vacuum molding.

[0171] In the above technical solution, by subjecting the etched first film blank to vacuum molding, the etched first film blank can not only present a planar state, but also a three-dimensional shape, and can present a corresponding shape according to needs, so that the electrochromic film 101 can be set on a curved surface, making the application range of the electrochromic film 101 wider.

[0172] According to some embodiments of the present application, forming the ion layer 2 on the transparent conductive layer side of the first film layer 1 includes: forming the ion layer 2 on the transparent conductive layer side of the first film layer 1 using an inkjet printing process.

[0173] In the above technical solution, since the first film layer 1 may be in a curved shape, an ion layer 2 is formed on the transparent conductive layer side of the first film layer 1 by adopting an inkjet printing process. Compared with the coating method in the related art, the formed ion layer 2 is more evenly distributed.

[0174] According to some embodiments of the present application, preparing the second film layer 3 includes: forming a second substrate layer 31 by a vacuum forming process; and evaporating a second transparent conductive layer 32 on the second substrate layer 31 to form the second film layer 3.

[0175] For example, evaporating the second transparent conductive layer 32 on the second substrate layer 31 to form the second film layer 3 includes: evaporating the second conductive layer on the second substrate layer 31 by a magnetron sputtering process.

[0176] In the above technical solution, the second substrate layer 31 is formed by adopting the vacuum forming process, so that the second substrate layer 31 can not only be in a planar state, but also in a three-dimensional shape, and can present a corresponding shape according to needs, so that the electrochromic film 101 can be set on a curved surface, making the application range of the electrochromic film 101 wider; since the second substrate layer 31 may be in a curved surface shape, the second conductive layer is evaporated on the second substrate layer 31 to form the second film layer 3. Compared with the coating method in the related art, the second conductive layer formed is more evenly distributed.

[0177] In this application, unless otherwise expressly defined, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. A person of ordinary skill in the art will understand the specific meanings of these terms in this application.

[0178] The terms "first," "second," "third," "fourth," etc. (if any) in this application are used to distinguish similar objects and are not necessarily used to describe a particular sequential order.

[0179] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0180] Unless otherwise specified, all steps of this application may be performed sequentially or randomly. For example, "the method includes steps A and B" means that the method may include steps A and B performed sequentially, or may include steps B and A performed sequentially. For example, "the method may also include step C" means that step C may be added to the method in any order. For example, the method may include steps A, B, and C, or steps A, C, and B, or steps C, A, and B, etc.
