However, electrochromic films in these technologies can only exhibit simple overall changes in transparency or color, limiting the content they can display and thus restricting their applications. Therefore, improvements are needed. Utility Model Content

By having a first transparent conductive layer of the electrochromic film include a plurality of sub-transparent conductive portions spaced apart along the surface of a first substrate layer and / or a second transparent conductive layer include a plurality of sub-transparent conductive portions spaced apart along the surface of a second substrate layer, the plurality of sub-transparent conductive portions can be controlled independently, so that the portions corresponding to the plurality of sub-transparent conductive portions on the electrochromic film exhibit different changes in transparency or color. The portions corresponding to the sub-transparent conductive portions can be combined to form patterns or text, making the display content of the electrochromic film richer and applicable to more scenarios.

[0004] This application also proposes an electrochromic decorative piece comprising the aforementioned electrochromic film.

[0005] This application also proposes a vehicle that includes the aforementioned electrochromic trim.

[0006] An electrochromic film according to a first aspect of this application includes: an ion layer including an electrochromic layer; a first film layer and a second film layer disposed on opposite sides of the ion layer in the thickness direction; the first film layer including a first substrate layer and a first transparent conductive layer, the first transparent conductive layer being located on the side of the first substrate layer closer to the ion layer; the second film layer including a second substrate layer and a second transparent conductive layer, the second transparent conductive layer being located on the side of the second substrate layer closer to the ion layer; the first transparent conductive layer including a plurality of sub-transparent conductive portions spaced apart along the surface of the first substrate layer and / or the second transparent conductive layer including a plurality of sub-transparent conductive portions spaced apart along the surface of the second substrate layer.

[0007] According to the embodiments of this application, the electrochromic film includes a first transparent conductive layer comprising a plurality of sub-transparent conductive portions spaced apart along the surface of a first substrate layer and / or a second transparent conductive layer comprising a plurality of sub-transparent conductive portions spaced apart along the surface of a second substrate layer. The plurality of sub-transparent conductive portions can be controlled independently, so that the portions corresponding to the plurality of sub-transparent conductive portions on the electrochromic film exhibit different changes in transparency or color. The portions corresponding to the sub-transparent conductive portions can be combined to form patterns or text, making the display content of the electrochromic film richer and applicable to more scenarios.

[0008] According to some embodiments of this application, a plurality of the sub-transparent conductive portions on the first substrate layer are arranged in an array.

[0009] In the above technical solution, by arranging the multiple sub-transparent conductive parts in an array on the first substrate layer, the corresponding parts of the sub-transparent conductive parts on the electrochromic film can form richer patterns or text.

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

[0011] In the above technical solution, by arranging the multiple sub-transparent conductive parts in an array on the second substrate layer, the corresponding parts of the sub-transparent conductive parts on the electrochromic film can form richer patterns or text.

[0012] According to some embodiments of this application, the electrochromic film further includes an appearance protective layer disposed on the side of the first film layer away from the ion layer.

[0016] According to some embodiments of this application, the electrochromic film further includes a patterned layer located on the side of the second film layer away from the ion layer.

[0017] In the above technical solution, by including a pattern layer in the electrochromic film, the patterns displayed by the electrochromic film can be richer. For example, the pattern layer can be a set texture or picture. By placing the pattern layer on the side of the second film layer away from the ion layer, an observer can see the pattern on the pattern layer through the electrochromic layer. When the transparency of the electrochromic layer changes, the pattern seen by the observer changes, enhancing the interactivity of the electrochromic film. For example, when the transparency of the electrochromic layer decreases, the pattern is hidden; when the transparency of the electrochromic layer increases, the pattern is revealed.

[0018] According to some embodiments of this application, the pattern layer is formed on the second substrate layer.

[0019] In the above technical solution, by forming the pattern layer on the second substrate layer, the connection between the pattern layer and the second substrate layer can be made more stable, avoiding the pattern layer from falling off or becoming misaligned, which would reduce the display effect of the pattern layer.

[0020] For example, the pattern layer is integrated onto the second substrate layer by at least one of the processes such as gravure printing, screen printing, and vapor deposition.

[0027] According to some embodiments of this application, the electrochromic decorative element further includes an adhesive layer located between the substrate skeleton and the electrochromic film.

[0028] In the above technical solution, by including an adhesive layer in the electrochromic decorative part, the connection between the substrate skeleton and the electrochromic film can be made more secure, preventing the electrochromic film from falling off the substrate skeleton.

[0029] According to some embodiments of this application, the thickness of the adhesive layer is d1, where 25μm≤d1≤250μm.

[0030] In the above technical solution, by making the thickness d1 of the adhesive layer not less than 25μm, the adhesive layer can more reliably fix and adhere the substrate skeleton and the electrochromic film, and more fully prevent the electrochromic film from falling off the substrate skeleton. By making the thickness d1 of the adhesive layer not greater than 250μm, while ensuring that the adhesive layer has a sufficient fixing and adhesion effect on the substrate skeleton and the electrochromic film, it can avoid the adhesive layer being too thick, which would make the electrochromic decorative part too thick and occupy more space.

[0045] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] The following is for reference. Figures 1-9 Describes an electrochromic film 101 according to an embodiment of this application.

[0047] Reference Figures 1-2 An electrochromic film 101 according to a first aspect embodiment of the present application includes: an ion layer 2, a first film layer 1, and a second film layer 3.

[0048] The ion layer 2 includes an electrochromic layer 23. The first film layer 1 and the second film layer 3 are disposed on opposite sides of the thickness direction of the ion layer 2. 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 closer 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 closer to the ion layer 2. 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 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.

[0049] 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 closer to the first film layer 1, and the electrochromic layer 23 is located on the side of the ion transport layer 22 closer to the second film layer 3.

[0050] For example, the electrochromic layer 23 can change its transparency or color according to the voltage between the first transparent conductive layer 12 and the second transparent conductive layer 32, thereby realizing the dynamic effects of the electrochromic film 101, enhancing the interaction between the electrochromic film 101 and relevant personnel.

[0051] 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 its transparency or color according to 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 its transparency or color according to 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 changes in transparency or color. 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 in related technologies.

[0052] When 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 different sub-transparent conductive parts 121, so that the electrochromic film 101 displays the changed pattern or text. This makes it more convenient to change these patterns or text.

[0053] According to the embodiments of this application, the electrochromic film 101, by including an electrochromic layer 23 in the ion layer 2 of the electrochromic film 101, allows the transparency or color of the electrochromic film 101 to dynamically change, achieving the dynamic effect of the electrochromic film 101 to reveal or hide, thereby enhancing the interaction capability between the electrochromic film 101 and relevant personnel; by including a plurality of sub-transparent conductive portions 12 spaced apart along the surface of the first substrate layer 11 in the first transparent conductive layer 12 of the electrochromic film 101, 1 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. The plurality of sub-transparent conductive portions 121 can be independently switched on and off or subjected to voltage changes, so that the portions corresponding to the plurality of sub-transparent conductive portions 121 on the electrochromic film 101 exhibit different changes in transparency or color. The portions corresponding to the sub-transparent conductive portions 121 can be combined to form special patterns or text without the need for additional accessories, and it is more convenient to modify these patterns or text.

[0054] Reference Figure 2 According to some embodiments of this application, a plurality of sub-transparent conductive portions 121 are arranged in an array on the first substrate layer 11.

[0055] In the above technical solution, by arranging a plurality of sub-transparent conductive parts 121 on the first substrate layer 11 in an array, the portions corresponding to the sub-transparent conductive parts 121 on the electrochromic film 101 can form richer patterns or text.

[0056] According to some embodiments of this application, a plurality of sub-transparent conductive portions 121 are arranged in an array on the second substrate layer 31.

[0057] In the above technical solution, by arranging a plurality of sub-transparent conductive portions 121 on the second substrate layer 31 in an array, the portions corresponding to the sub-transparent conductive portions 121 on the electrochromic film 101 can form richer patterns or text.

[0058] Reference Figure 1 According to some embodiments of this application, the electrochromic film 101 further includes an appearance protection layer 41, which is disposed on the side of the first film layer 1 away from the ion layer 2.

[0059] In the above technical solution, by making the electrochromic film 101 further include an appearance protection layer 41, and by making the appearance protection layer 41 disposed 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.

[0060] Reference Figure 1According to some embodiments of this 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.

[0061] In the above technical solution, by making the first transparent conductive layer 12 include a plurality of sub-transparent conductive portions 121 arranged at intervals along the surface of the first substrate layer 11, the sub-transparent conductive portions 121 can be closer to the relevant personnel when the electrochromic film 101 is assembled onto the decoration, so that the development of the electrochromic film 101 is clearer.

[0062] Reference Figure 1 According to some embodiments of this application, the electrochromic film 101 further includes a pattern layer 42 located on the side of the second film layer 3 away from the ion layer 2.

[0063] In the above technical solution, by including a pattern layer 42 in the electrochromic film 101, the patterns presented by the electrochromic film 101 can be richer. For example, the pattern layer 42 can be a set texture or picture. By positioning the pattern layer 42 on the side of the second film layer 3 away from the ion layer 2, relevant personnel 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 relevant personnel can change, enhancing the interactivity 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 is revealed.

[0064] Reference Figure 1 According to some embodiments of this application, the pattern layer 42 is formed on the second substrate layer 31.

[0065] In the above technical solution, by forming the pattern layer 42 on the second substrate layer 31, the connection between the pattern layer 42 and the second substrate layer 31 can be made more stable, and the pattern layer 42 can be prevented from falling off or misaligning, which would reduce the display effect of the pattern layer 42.

[0066] Reference Figure 3 An electrochromic decorative element 100 according to a second aspect embodiment of this application includes: an electrochromic film 101 according to a first aspect embodiment of this application, a driving module chip, and an electrochromic module chip. Each sub-transparent conductive portion 121 is electrically connected to the driving module chip, which receives a color-changing command and controls the voltage parameters of each sub-transparent conductive portion 121 according to the received color-changing command. Each sub-transparent conductive portion 121 is electrically connected to the electrochromic module chip, which is electrically connected to the driving module chip. The electrochromic module chip calculates the voltage parameters of each sub-transparent conductive portion 121 according to the color-changing command received by the driving module chip.

[0067] According to the embodiments of this application, the electrochromic decorative component 100, by including the electrochromic film 101 according to the first aspect of this application, can be combined to form special patterns or text without the need for additional accessories, and it is more convenient to modify these patterns or text. By including a driving module chip and an electrochromic module chip in the electrochromic decorative component 100, the driving module chip can convert the received instruction signal into a voltage parameter signal and transmit the voltage parameter signal to the electrochromic module chip. The electrochromic module chip can calculate the voltage parameter of each sub-transparent conductive part 121 according to the color-changing instruction received by the driving module chip, and control the voltage of the multiple sub-transparent conductive parts 121 respectively, thereby controlling the color or transparency of the electrochromic decorative component 100 part corresponding to the multiple sub-transparent conductive parts 121 respectively, so that the electrochromic decorative component 100 can display the set pattern. Furthermore, it is more convenient to control the transparency or color of the electrochromic film 101 by controlling the voltage.

[0068] Reference Figure 3 According to some embodiments of this application, the electrochromic decorative element 100 further includes a substrate skeleton 6, which is located on one side of the second substrate layer 31 of the electrochromic film 101.

[0069] In the above technical solution, the electrochromic decorative part 100 also includes a substrate skeleton 6, which can provide support for the electrochromic film 101 and prevent the electrochromic film 101 from deforming, which would reduce or damage the display effect.

[0070] For example, the pre-formed 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. After cooling, the electrochromic decorative part 100 is formed.

[0071] For example, the skeleton can be made of transparent or opaque material. When the skeleton is made of opaque material, ABS or PC+ABS can be used; when the skeleton is made of transparent material, PC substrate can be used.

[0072] According to some embodiments of this application, the thickness of the substrate skeleton 6 is d2, where 2.5mm≤d2≤3mm.

[0073] 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.

[0074] In the above technical solution, by making the thickness d2 of the substrate skeleton 6 not less than 2.5mm, the substrate skeleton 6 can have sufficient strength to avoid deformation and damage to the electrochromic decorative part 100; by making the thickness d2 of the substrate skeleton 6 not greater than 3mm, while ensuring that the substrate skeleton 6 has sufficient strength, it can avoid the substrate skeleton 6 being too thick, which would make the electrochromic decorative part 100 too thick and occupy more space.

[0075] Reference Figure 3 According to some embodiments of this application, the electrochromic decorative element 100 further includes an adhesive layer 5, which is located between the substrate skeleton 6 and the electrochromic film 101.

[0076] For example, the adhesive layer 5 can be OCA optical adhesive, which is a substrate-free double-sided pressure-sensitive adhesive.

[0077] In the above technical solution, by including an adhesive layer 5 in the electrochromic decorative part 100, the connection between the substrate skeleton 6 and the electrochromic film 101 can be made more secure, preventing the electrochromic film 101 from falling off the substrate skeleton 6.

[0078] Reference Figure 3 According to some embodiments of this application, the thickness of the adhesion layer 5 is d1, where 25μm≤d1≤250μm.

[0079] For example, the value of d1 can be 25μm, 30μm, 50μm, 80μm, 100μm, 150μm, 200μm, 250μm, etc.

[0080] In the above technical solution, by making the thickness d1 of the adhesive layer 5 not less than 25μm, the adhesive layer 5 can more reliably fix and adhere the substrate skeleton 6 and the electrochromic film 101, and more fully prevent the electrochromic film 101 from falling off the substrate skeleton 6. By making the thickness d1 of the adhesive layer 5 not greater than 250μm, while ensuring that the adhesive layer 5 has a sufficient fixing and adhering effect on the substrate skeleton 6 and the electrochromic film 101, it can avoid the adhesive layer 5 being too thick, which would make the electrochromic decorative part 100 too thick and occupy more space.

[0081] Reference Figure 3 According to some embodiments of this application, the substrate skeleton 6 is a transparent part, and the electrochromic decorative part 100 further includes a backlight layer 7, which is located on the side of the substrate skeleton 6 opposite to the electrochromic film 101.

[0082] For example, the backlight layer 7 can emit light of different wavelengths. When the backlight layer 7 is integrated with the electrochromic film 101, it can create an ambient lighting effect.

[0083] In the above technical solution, the electrochromic decorative component 100 also includes a backlight layer 7, and the substrate frame 6 is made transparent, allowing relevant personnel to see the light emitted by the backlight layer 7 through the substrate frame 6, thereby enhancing the functionality of the electrochromic decorative component 100. For example, at night or in insufficient lighting, the backlight layer 7 can emit light, allowing relevant personnel to see the content displayed by the electrochromic decorative component 100 more clearly.

[0084] According to some embodiments of this application, the transparency of the substrate skeleton 6 is ≥90%.

[0085] For example, the transparency of the substrate skeleton 6 can be 90%, 92%, 94%, 95%, 96%, 98%, 100%, etc.

[0086] In the above technical solution, by making the transparency of the substrate skeleton 6 ≥ 90%, the light transmission performance 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.

[0087] Reference Figure 3 According to some embodiments of this application, the electrochromic decorative part 100 further includes an adhesive layer 5, which is located between the substrate skeleton 6 and the electrochromic film 101. The transparency of the adhesive layer 5 is ≥90%, and the haze of the adhesive layer 5 is ≤1.0%.

[0088] For example, the transparency of the adhesive layer 5 can be 90%, 92%, 94%, 95%, 96%, 98%, 100%, etc.; the haze of the adhesive layer 5 can be 1.0%, 0.8%, 0.6%, 0.4%, 0.2%, etc.

[0089] In the above technical solution, by including an adhesive layer 5 in the electrochromic decorative part 100, the connection between the substrate skeleton 6 and the electrochromic film 101 can be made stronger, 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 transmission performance of the adhesive layer 5 can be improved, and relevant personnel can more easily see the light emitted by the backlight panel through the adhesive layer 5.

[0090] A vehicle according to a third aspect of this application includes: a control module and an electrochromic decorative element 100 according to a second aspect of this application, wherein a drive module chip is electrically connected to the control module, and the control module is used to issue a color-changing command to the drive module chip.

[0091] According to the embodiments of this application, the vehicle includes an electrochromic decorative element 100 according to the second aspect of this application. The electrochromic decorative element 100 can be combined to form special patterns or text without the need for additional accessories, and it is more convenient to modify these patterns or text.

[0092] According to some embodiments of this application, the electrochromic trim 100 is installed in the interior of a vehicle.

[0093] In the above technical solution, by installing the electrochromic decorative part 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.

[0094] Reference Figure 4 According to the control method of the electrochromic decorative part 100 of the fourth aspect embodiment of this application, the electrochromic decorative part 100 is the electrochromic decorative part 100 according to the second aspect embodiment of this application, and the control method of the electrochromic decorative part 100 includes: The control module receives the color-changing command; The control module sends the received color-changing command to the driver module chip; The electrochromic module chip calculates the voltage parameters of each sub-transparent conductive part 121 according to the color-changing command received by the driving module chip; The driving module chip applies a corresponding voltage to each sub-transparent conductive part 121 based on the voltage parameters of each sub-transparent conductive part 121 calculated by the electrochromic module chip.

[0095] 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 the range of ±0.1V-300V. The electrochromic module chip, in conjunction with the input required command, distributes different positive and negative voltage values ​​and applies them to different sub-transparent conductive parts 121 respectively, thereby realizing the color or transparency change of the different sub-transparent conductive parts 121.

[0096] For example, the control module can also be powered by a programmable power supply.

[0097] According to the control method of the electrochromic decorative part 100 in the embodiments of this application, by having the electrochromic module chip calculate the voltage parameters of each sub-transparent conductive part 121 according to the color-changing command received by the driving module chip, and then having the driving module chip apply a corresponding voltage to each sub-transparent conductive part 121 respectively, the voltage of multiple sub-transparent conductive parts 121 can be controlled respectively, thereby controlling the color or transparency of the electrochromic decorative part 100 corresponding to the multiple sub-transparent conductive parts 121 respectively, so that the electrochromic decorative part 100 can display a set pattern.

[0098] According to some embodiments of this application, before applying a corresponding voltage to each sub-transparent conductive portion 121, the method includes: driving the module chip to identify the coordinates of each sub-transparent conductive portion 121.

[0099] In the above technical solution, before applying a corresponding voltage to each sub-transparent conductive part 121, the driving module chip first identifies the coordinates of each sub-transparent conductive part 121. This allows the driving module chip to identify the position of each sub-transparent conductive part 121, so that the driving module chip can calculate the voltage applied to each sub-transparent conductive part 121.

[0100] According to some embodiments of this application, the driving module chip identifies the coordinates of each sub-transparent conductive part 121, including: identifying the row number and column number of each sub-transparent conductive part 121.

[0101] For example, multiple sub-transparent conductive parts 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 part 121 within the electrochromic film 101 can be determined using the intersection values ​​of the rows and columns. For instance, the sub-transparent conductive part 121 located in the leftmost column and topmost row of all sub-transparent conductive parts 121 is located in column 1, row 1. The driving module can identify the row and column number of each sub-transparent conductive part 121.

[0102] In the above technical solution, by enabling the driving module chip to identify the row and column number of each sub-transparent conductive part 121, the position of the sub-transparent conductive part 121 is transformed into a row and column number that is easier for the driving module chip to identify. This makes it easier for the driving module chip to distinguish the position of each sub-transparent conductive part 121, thereby making it easier for the driving module chip to calculate the voltage required for each sub-transparent conductive part 121.

[0103] Reference Figure 7 According to some embodiments of this application, the color-changing instruction includes: controlling the voltage parameter of a single sub-transparent conductive part 121 to change linearly.

[0104] For example, the voltage parameters of a single sub-transparent conductive part 121 can be controlled to change linearly from -15V to 15V.

[0105] In the above technical solution, by making the voltage parameter of the control of a single sub-transparent conductive part 121 change linearly, the voltage parameter changes gradually. Compared with making the voltage parameter change between a few set values, the transparency or color displayed by the electrochromic decorative part 100 at the corresponding position of each sub-transparent conductive part 121 can have more forms, and the transparency or color displayed by the electrochromic decorative part 100 is richer.

[0106] Reference Figure 7According to some embodiments of this application, the color-changing instruction includes synchronous development, which includes: simultaneously applying the same initial voltage to each sub-transparent conductive portion 121; and the voltage applied to each sub-transparent conductive portion 121 changing according to the same preset rate of change.

[0107] For example, Figure 7 From left to right, the voltage applied to each sub-transparent conductive part 121 changes at the same preset rate, so that the electrochromic decorative part 100 presents the same transparency as a whole and the transparency changes synchronously.

[0108] In the above technical solution, by including synchronous development in the color-changing command, the electrochromic decorative parts 100 at the corresponding positions of multiple sub-transparent conductive parts 121 can synchronously change their transparency or color, which can meet more user needs for the electrochromic decorative parts 100 and improve the interactivity of the electrochromic decorative parts 100. By applying the same initial voltage to each sub-transparent conductive part 121 simultaneously when the color-changing command is synchronous development, and the voltage applied to each sub-transparent conductive part 121 changes according to the same preset rate, the voltage received by each sub-transparent conductive part 121 can be the same at the same time, so that the electrochromic decorative parts 100 as a whole presents the same transparency or color.

[0109] According to some embodiments of this application, a plurality of sub-transparent conductive parts 121 are divided into multiple groups, each group including at least one sub-transparent conductive part 121. The color change instruction includes gradient development, which includes: applying the same voltage to the sub-transparent conductive parts 121 in the same group, and applying different voltages to the multiple groups of sub-transparent conductive parts 121 at the same time.

[0110] For example, in the initial state, all the sub-transparent conductive parts 121 are opaque. The driving module drives the electrochromic module chip to apply voltage to the sub-transparent conductive parts 121 of the first column, and the voltage value changes according to a set rate. After a set time when the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 of the first group, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 of the second group, and the voltage value changes according to a set rate. After a set time, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 of the third group, and finally applies voltage to the sub-transparent conductive parts 121 of the last group, so that the electrochromic film 101 forms a gradual development change.

[0111] In the above technical solution, by including gradient development in the color-changing command, the electrochromic decorative parts 100 at the corresponding positions of different groups of sub-transparent conductive parts 121 can have different transparency or color at the same time, which can meet more user needs for electrochromic decorative parts 100 and improve the interactivity of electrochromic decorative parts 100. By applying the same voltage to the same group of sub-transparent conductive parts 121 when the color-changing command is gradient 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 can present the same transparency or color at the same time, while the electrochromic decorative parts 100 corresponding to the sub-transparent conductive parts 121 in different groups can present different transparency or color at the same time.

[0112] According to some embodiments of this application, the voltages applied to the multiple sets of transparent conductive parts 121 at the same time are different, including: according to the arrangement order of the multiple sets of transparent conductive parts 121, the voltages applied to the multiple sets of transparent conductive parts 121 at the same time are sequentially increased or decreased.

[0113] In the above technical solution, by making the voltage applied to the multiple sets of transparent conductive parts 121 increase or decrease sequentially at the same time, the transparency or color of the electrochromic decorative part 100 at the same time can present a gradient effect, which can meet more user needs for the electrochromic decorative part 100 and enhance the interactive capability of the electrochromic decorative part 100.

[0114] According to some embodiments of this application, the voltage applied to the multiple sets of sub-transparent conductive parts 121 at the same time is sequentially increased or decreased according to the arrangement order of the multiple sets of sub-transparent conductive parts 121, including: applying the same initial voltage to each set of sub-transparent conductive parts 121 in sequence according to the arrangement order of the multiple sets of sub-transparent conductive parts 121; and changing the voltage applied to each set of sub-transparent conductive parts 121 according to the same preset rate of change.

[0115] In the above technical solution, by applying the same initial voltage to each group of sub-transparent conductive parts 121 in sequence according to the arrangement order of the multiple groups of sub-transparent conductive parts 121, and by changing the voltage applied to each group of sub-transparent conductive parts 121 according to the same preset rate of change, the gradient effect of the transparency or color of the electrochromic decorative part 100 at the same moment can be made more stable, which can meet more user needs for the electrochromic decorative part 100 and improve the interactive capability of the electrochromic decorative part 100.

[0116] According to some embodiments of this application, the time interval between applying voltage to two adjacent sets of transparent conductive parts 121 is 0.1s-0.5s.

[0117] In the above technical solution, by making the time interval between applying voltage to two adjacent sets of transparent conductive parts 121 0.1s-0.5s, the relevant users can more clearly experience the gradient effect presented by the electrochromic decorative part 100.

[0118] According to some embodiments of this application, multiple sets of transparent conductive portions 121 are arranged side by side; or, multiple sets of transparent conductive portions 121 are arranged sequentially from the center of the electrochromic film 101 to the outer edge of the electrochromic film 101.

[0119] For example, in the initial state, all the sub-transparent conductive parts 121 are opaque. The driving module drives the electrochromic module chip to apply voltage to the first column of sub-transparent conductive parts 121, and the voltage value changes according to a set rate. After a set time, the electrochromic module chip applies voltage to the first column of sub-transparent conductive parts 121, and the voltage value changes according to a set rate. After a set time, the electrochromic module chip applies voltage to the third column of sub-transparent conductive parts 121, and finally applies voltage to the last column of sub-transparent conductive parts 121, so that the electrochromic film 101 forms a gradual development change from left to right.

[0120] For example, in the initial state, all the sub-transparent conductive parts 121 are opaque. At least one sub-transparent conductive part 121 at 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 a set rate. After a set time when the electrochromic module chip applies voltage to the origin, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 around the origin, and the voltage value changes according to a set rate. After a set time, the electrochromic module chip applies voltage to the sub-transparent conductive parts 121 around the sub-transparent conductive parts 121 around which the voltage was previously applied. Finally, the electrochromic module chip applies voltage to the outermost sub-transparent conductive parts 121, and finally the electrochromic film 101 forms a gradual development change from the center to the periphery.

[0121] In the above technical solution, by arranging multiple sets of sub-transparent conductive parts 121 side by side, the electrochromic decorative part 100 can exhibit a gradient effect along the side-by-side direction of the sub-transparent conductive parts 121. For example, if the multiple sets of sub-transparent conductive parts 121 are arranged side by side in the left-right direction, the electrochromic decorative part 100 can exhibit a gradient effect in the left-right direction; as another example, if the multiple sets of sub-transparent conductive parts 121 are arranged side by side in the up-down direction, the electrochromic decorative part 100 can exhibit a gradient effect in the up-down direction. By arranging the multiple sets of sub-transparent conductive parts 121 sequentially from the center of the electrochromic film 101 to the outer edge of the electrochromic film 101, the electrochromic decorative part 100 can exhibit a gradient effect radiating from the center. For example, the electrochromic decorative part 100 can exhibit a gradient effect radiating outward from the center, or it can exhibit a gradient effect from the periphery to the center.

[0122] Reference Figure 8 According to some embodiments of this application, the color-changing instruction includes mosaic development, which includes randomly applying a voltage to each sub-transparent conductive portion 121.

[0123] For example, Figure 8 The left image shows the state when no color-changing command has been received. Figure 8 The right image shows the state after receiving the mosaic development and color change command, and the electrochromic decorative part 100 presents a mosaic visual effect.

[0124] In the above technical solution, by randomly applying voltage to each sub-transparent conductive part 121, the electrochromic decorative part 100 can present a mosaic visual effect, which can meet more user needs for the electrochromic decorative part 100 and enhance the interactive capabilities of the electrochromic decorative part 100.

[0125] Reference Figure 4 According to some embodiments of this application, the control module receives a color-changing command, including: the color-changing command received by the control module is sent to the control module by at least one of an ambient light sensor, an ambient light, a mobile APP program, and a seat status detection module.

[0126] For example, an ambient light sensor includes a sunlight sensor. The sunlight sensor detects ambient light. When the ambient light is dim, it is determined to be a nighttime driving scenario. The sunlight sensor sends a color-changing command to the control module, and the control module controls the transparency of the electrochromic film 101 to increase.

[0127] For example, the control module receives a color-changing command from the ambient light. When the ambient light changes color, the control module controls the electrochromic film 101 to change color to match the color of the ambient light.

[0128] For example, relevant personnel can transmit color-changing instructions to the Bluetooth module via a mobile app. The Bluetooth module then sends the color-changing instructions to the control module, which in turn controls the electrochromic film 101 to display the set pattern or text.

[0129] For example, when the seat status detection module detects that the seat is in a reclining state, i.e., a zero-gravity state, it determines that it is an entertainment mode scenario and sends a color-changing command to the control module. The control module controls the transparency of the electrochromic film 101 to increase, making the electrochromic film 101 semi-transparent, or making the electrochromic film 101 present a gradient effect.

[0130] In the above technical solution, by enabling the control module to receive color-changing commands sent to the control module from at least one of the ambient light sensor, ambient light, mobile 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 needs of the scene or relevant personnel, thereby enhancing the interactivity of the electrochromic decorative part 100.

[0131] Reference Figure 9 According to the fifth aspect embodiment of the present application, the method for preparing the electrochromic film 101 is characterized in that the electrochromic film 101 is the electrochromic film 101 according to the first aspect embodiment of the present application, and the method for preparing the electrochromic film 101 includes: Prepare a first preform with a transparent conductive layer; The transparent conductive layer of the first film preform is etched using an etching process to form multiple spaced sub-transparent conductive parts 121; The etched first preform is processed into a preset shape to form the first film layer 1; An ion layer 2 is formed on the transparent conductive layer side of the first film layer 1; Preparation of the second film layer 3; The second film layer 3 is laminated together with the first film layer 1 on which the ion layer 2 is formed to form an electrochromic film 101.

[0132] For example, a chemical etching process can be used to etch the transparent conductive layer of the first film blank to form multiple spaced sub-transparent conductive portions 121.

[0133] For example, if 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, then performing vacuum forming and stretching in the horizontal and vertical directions to form a three-dimensional curved shape, and then removing the excess substrate material around the first film blank after forming.

[0134] For example, forming an ion layer 2 on the transparent conductive layer side of the first film layer 1 includes: uniformly spraying liquid raw materials onto the first film layer 1 in sequence using an inkjet printer to form an ion storage layer 21, an ion transport layer, and an electrochromic layer 23.

[0135] According to the method for preparing the electrochromic film 101 according to the embodiments of this application, a plurality of spaced sub-transparent conductive parts 121 are formed by etching the transparent conductive layer of the first film blank using an etching process. This allows the plurality of sub-transparent conductive parts 121 to undergo voltage changes independently, resulting in different transparency or color changes on the parts corresponding to the plurality of sub-transparent conductive parts 121 on the electrochromic film 101. The parts corresponding to the sub-transparent conductive parts 121 can be combined to form special patterns or text without the need for additional accessories, and it is more convenient to modify these patterns or text. 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 into different shapes according to requirements, which can meet more needs of relevant personnel.

[0136] According to some embodiments of this application, the etching of the first preform is processed into a preset shape, including: performing vacuum forming on the etched first preform.

[0137] In the above technical solution, by vacuum forming the etched first film blank, 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 the requirements. Thus, the electrochromic film 101 can be set on a curved surface, making the application range of the electrochromic film 101 wider.

[0138] According to some embodiments of this application, forming an 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.

[0139] In the above technical solution, since the first film layer 1 may be curved, an ion layer 2 is formed on the transparent conductive layer side of the first film layer 1 by using inkjet printing process. Compared with the coating method in related technologies, the ion layer 2 formed is more uniformly distributed.

[0140] According to some embodiments of this application, the preparation of the second film layer 3 includes: forming a second substrate layer 31 using a vacuum forming process; and depositing a second transparent conductive layer 32 on the second substrate layer 31 by vapor deposition to form the second film layer 3.

[0141] For example, depositing a second transparent conductive layer 32 on the second substrate layer 31 to form a second film layer 3 includes: depositing the second conductive layer on the second substrate layer 31 by magnetron sputtering.

[0142] In the above technical solution, by using a vacuum forming process to form the second substrate layer 31, the second substrate layer 31 can not only present a planar state, but also a three-dimensional shape, and can present a corresponding shape according to the requirements. This allows the electrochromic film 101 to be set on a curved surface, making the application range of the electrochromic film 101 wider. Since the second substrate layer 31 may be curved, by evaporating a second conductive layer on the second substrate layer 31 to form the second film layer 3, the distribution of the second conductive layer is more uniform compared with the coating method in related technologies.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0144] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0145] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
