具体实施方式Detailed ways

下面详细描述本申请的具体内容，所述示例性的结构以及方法流程在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。The specific content of the present application is described in detail below. The exemplary structure and method flow are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and should not be construed as limiting the present application.

在本申请的一个方面，本申请提出了一种壳体。参考图1，该壳体包括：第一基板100、电致变色单元200、第二基板300以及图案单元400。其中，电致变色单元200设置在第一基板100上，图案单元400设置在第二基板300上，第二基板300贴合在电致变色单元200远离第一基板100的一侧。由此，给该壳体施加电压，可以使电致变色单元在透明和不透明之间切换，使得。此时整个壳体可以从遮盖力强的颜色(电致变色单元200的显色状态具有的颜色)变为第二基板上的图案效果(电致变色单元200变得透明而显示底层颜色)，从而使壳体呈现更加丰富多彩的效果。In one aspect of the application, the application proposes a housing. Referring to FIG. 1, the case includes: a first substrate 100, an electrochromic unit 200, a second substrate 300, and a pattern unit 400. The electrochromic unit 200 is disposed on the first substrate 100, the pattern unit 400 is disposed on the second substrate 300, and the second substrate 300 is attached to a side of the electrochromic unit 200 away from the first substrate 100. Thus, applying a voltage to the case can switch the electrochromic unit between transparent and opaque, so that. At this time, the entire housing can be changed from a color with a strong hiding power (the color of the electrochromic unit 200 in the color rendering state) to a pattern effect on the second substrate (the electrochromic unit 200 becomes transparent and displays the underlying color) So that the shell presents a more colorful effect.

为了便于理解，下面首先对该壳体进行简单说明：In order to facilitate understanding, the shell is briefly explained below:

如前所述，目前的电子设备壳体呈现的外观效果通常是由印刷形成的，具体的，将颜色或者纹理图案形成在玻璃基板上，例如印刷在玻璃基板上从而使壳体呈现一定的颜色或者纹理图案。然而，上述壳体只能呈现多种图案效果中的一种，无法实现多种效果之间的切换，从而导致壳体的外观较单调，无法满足用户的需求。As mentioned earlier, the appearance effect of the current electronic device casing is usually formed by printing. Specifically, the color or texture pattern is formed on a glass substrate, for example, printed on the glass substrate so that the casing presents a certain color. Or texture pattern. However, the above-mentioned shell can only present one of a variety of pattern effects, and cannot switch between the multiple effects, resulting in a monotonous appearance of the shell, which cannot meet the needs of users.

本申请通过在壳体中设置电致变色单元，并通过控制电压使电致变色单元在透明和不透明之间切换，使得整个壳体可以从一种颜色变为显示第二基板上图案单元的效果，从而使壳体呈现更加丰富多彩的效果。In this application, the electrochromic unit is provided in the casing, and the electrochromic unit is switched between transparent and opaque by controlling the voltage, so that the entire casing can be changed from one color to display the effect of the pattern unit on the second substrate. , So that the shell presents a more colorful effect.

下面对该壳体的各个结构进行详细说明：Each structure of the shell is described in detail below:

参考图2，电致变色单元200包括：第一透明导电层210、电致变色层220、电解质层230、离子储存层240以及第二透明导电层250。其中，第一透明导电层210设置在第一基板100上，电致变色层220设置在第一透明导电层210远离第一基板100的一侧，电解质层230设置在电致变色层220远离第一透明导电层210的一侧，离子储存层240设置在电解质层230远离电致变色层220的一侧，第二透明导电层250设置在离子储存层240远离电解质层230的一侧。由此，给壳体施加电压时，电致变色单元会在透明与不透明状态之间切换，使得壳体呈现更加丰富多彩的效果。根据本申请的实施例，第一基板100为透明结构，具体的可以为玻璃或者塑胶。由此，电致变色层产生的颜色可以透过第一透明导电层以及第一基板呈现出来。根据本申请的实施例，形成第一基板100的塑胶可以为聚对苯二甲酸乙二醇酯或者聚碳酸酯，由此，可以增强壳体的韧性，使壳体具有耐摔性能。Referring to FIG. 2, the electrochromic unit 200 includes a first transparent conductive layer 210, an electrochromic layer 220, an electrolyte layer 230, an ion storage layer 240, and a second transparent conductive layer 250. The first transparent conductive layer 210 is disposed on the first substrate 100, the electrochromic layer 220 is disposed on a side of the first transparent conductive layer 210 away from the first substrate 100, and the electrolyte layer 230 is disposed on the electrochromic layer 220 away from the first substrate. On one side of a transparent conductive layer 210, the ion storage layer 240 is disposed on the side of the electrolyte layer 230 away from the electrochromic layer 220, and the second transparent conductive layer 250 is disposed on the side of the ion storage layer 240 away from the electrolyte layer 230. Therefore, when a voltage is applied to the casing, the electrochromic unit switches between transparent and opaque states, so that the casing exhibits a more colorful effect. According to the embodiment of the present application, the first substrate 100 is a transparent structure, and specifically may be glass or plastic. Therefore, the color generated by the electrochromic layer can be displayed through the first transparent conductive layer and the first substrate. According to the embodiment of the present application, the plastic forming the first substrate 100 may be polyethylene terephthalate or polycarbonate, so that the toughness of the casing can be enhanced and the casing has a drop-resistant performance.

第一透明导电层210可以为氧化铟锡(ITO)或者纳米银，由此，第一透明导电层可以具有良好的导电性以及较高的透明度。具体地，第一透明导电层210的方阻小于50Ω，如可以小于20Ω。由此，一方面，该第一透明导电层210具有良好的导电性能，方阻较小可以减少能量的损耗，且使变色时间控制在较短的范围内。另一方面，该第一透明导电层具有较高的透明度，可以较好的呈现电致变色层产生的颜色。The first transparent conductive layer 210 may be indium tin oxide (ITO) or nano-silver. Therefore, the first transparent conductive layer 210 may have good conductivity and high transparency. Specifically, the square resistance of the first transparent conductive layer 210 is less than 50Ω, for example, it can be less than 20Ω. Therefore, on the one hand, the first transparent conductive layer 210 has good conductivity, a small square resistance can reduce energy loss, and control the color changing time in a short range. On the other hand, the first transparent conductive layer has higher transparency, and can better display the colors generated by the electrochromic layer.

关于电致变色层的具体材料不受特别限制，本领域技术人员可以根据具体情况进行选择。例如，电致变色层220可以是由无机电致变色材料形成的。或者，电致变色层220还可以是由有机电致变色材料形成的。上述电致变色材料可以在不同的电压大小和方向下呈现不同的电致变色颜色。当电致变色层由有机电致变色材料形成时，电致变色层可以呈现的颜色多样，且变色时间短，从施加电压到完全变色只需要1秒时间，时效性高。电致变色层220的厚度可以不大于200nm。发明人发现，电致变色层的厚度高于上述值时，会导致变色时间加长，影响电致变色的效果。由此，将电致变色层的厚度设置在上述范围时，可以使变色时间控制在较短的范围内，提高时效性。The specific material of the electrochromic layer is not particularly limited, and those skilled in the art can select according to specific conditions. For example, the electrochromic layer 220 may be formed of an inorganic electrochromic material. Alternatively, the electrochromic layer 220 may be formed of an organic electrochromic material. The above electrochromic materials can exhibit different electrochromic colors under different voltage magnitudes and directions. When the electrochromic layer is formed of an organic electrochromic material, the electrochromic layer can exhibit a variety of colors, and the color change time is short. It takes only 1 second from the application of voltage to complete color change, and the timeliness is high. The thickness of the electrochromic layer 220 may be not more than 200 nm. The inventors found that when the thickness of the electrochromic layer is higher than the above value, it will lead to a longer discoloration time and affect the effect of the electrochromic. Therefore, when the thickness of the electrochromic layer is set in the above range, the discoloration time can be controlled within a short range, and the timeliness can be improved.

参考图10，可以通过选择构成电致变色层的材料，使得上述材料在某种电压状态下(例如，无电压或者某个特定电压值V1)为纯黑色或者其他遮盖力强的颜色，此时壳体1000所显示的是电致变色层所具有的颜色，如图10中的(b)所示。在另外一个状态下(例如，某特定电压值V2)上述电致变色层材料的透光率大大增加，变为透明状态。此时，第二基板上的图案或者颜色便会透过电致变色单元呈现在壳体1000上，此时壳体1000所显示的是图案单元所具有的外观，如图10中的(a)所示。由此，当电致变色层为不透明状态时，壳体显示为电致变色层的颜色，例如纯黑色或者其他遮盖力强的颜色。当电致变色层为透明状态时，壳体显示为第二基板上的图案或者颜色，即图案单元的图案或颜色，从而通过图案单元的隐藏或显示提供一种外观可调的壳体，，实现壳体多种外观效果的切换。Referring to FIG. 10, by selecting a material constituting the electrochromic layer, the above material is pure black or another color with strong hiding power under a certain voltage state (for example, no voltage or a specific voltage value V1). The housing 1000 displays the color of the electrochromic layer, as shown in FIG. 10 (b). In another state (for example, a specific voltage value V2), the light transmittance of the material of the electrochromic layer is greatly increased and becomes transparent. At this time, the pattern or color on the second substrate will be presented on the casing 1000 through the electrochromic unit, and at this time, the casing 1000 displays the appearance of the pattern unit, as shown in (a) of FIG. 10. As shown. Therefore, when the electrochromic layer is in an opaque state, the shell displays the color of the electrochromic layer, such as pure black or other colors with strong hiding power. When the electrochromic layer is in a transparent state, the shell is displayed as a pattern or color on the second substrate, that is, the pattern or color of the pattern unit, thereby providing a shell with an adjustable appearance through the hiding or display of the pattern unit, Realize the switching of various appearance effects of the shell.

或者，也可以选择电致变色层220的构成材料，令其在不同的电压状态下可以呈现不同的颜色。通过调节电致变色层220的厚度，而令电致变色层220具有一定的透过率。因此，在不同电压下，用户从第一基板100一侧，观察到的是电致变色层220的两种不同颜色，分别和下方图案单元的外观效果的叠加视觉效果。Alternatively, the constituent materials of the electrochromic layer 220 may also be selected so that they can exhibit different colors under different voltage states. By adjusting the thickness of the electrochromic layer 220, the electrochromic layer 220 has a certain transmittance. Therefore, under different voltages, the user observes from the side of the first substrate 100 the two different colors of the electrochromic layer 220, which respectively superimpose the visual effects of the appearance effect of the pattern unit below.

或者，也可以选择电致变色层220的构成材料，令其在不同的电压状态下可以呈现不同的颜色，而非仅仅在透明态和不透明态之间转换。或者，也可以通过调节电致变色层220的厚度，而令电致变色层220在透明态时也具有一定的颜色，而非完全的透明。因此，在不同电压下，用户可观察到的是电致变色层220的两种不同颜色(或是同种颜色的深或浅)，分别和下方图案单元的外观效果的叠加视觉效果。Alternatively, the constituent material of the electrochromic layer 220 may also be selected so that it can present different colors under different voltage states, instead of merely switching between a transparent state and an opaque state. Alternatively, the thickness of the electrochromic layer 220 can also be adjusted so that the electrochromic layer 220 also has a certain color in the transparent state, instead of being completely transparent. Therefore, under different voltages, the user can observe the visual effects of the two different colors (or the same color dark or light) of the electrochromic layer 220 and the appearance effect of the pattern unit below.

电解质层230可以是由胶状材料构成的。具体的，电解质层230可以包括胶材、增塑剂、导电离子以及溶剂。由此，一方面，电解质层可以作为离子通道，使离子储存层中的离子穿过电解质层进入电致变色层中，与电致变色材料发生反应，使电致变色层发生颜色变化。另一方面，电解质层可以作为电致变色层以及离子储存层的间隔物质，防止离子储存层中的离子脱掺杂返回离子储存层中，从而保证电致变色层变色的稳定性。具体的，以有机电致变色材料为例，在给第一透明导电层210以及第二透明导电层250施加电压时，离子储存层240中的离子通过电解质层230进入电致变色层220中，离子储存层240中的离子与电致变色层220中的聚合物发生氧化还原反应，即离子的掺杂或脱掺杂，掺杂或脱掺杂后的聚合物颜色发生变化，使电致变色层220呈现不同的颜色。由胶状材料形成的电解质层，与液态电解质相比具有高稳定性、寿命长等优点，不会产生鼓泡或者电解液外漏等不良现象，从而可以进一步提高该壳体的使用寿命。为了进一步提高电致变色层220的变色稳定性，可以将电解质层230的厚度设计的稍厚，例如，电解质层230的厚度可以为100-200μm。由此，可以进一步防止离子脱掺杂返回到离子储存层中，进一步提高电致变色层变色的稳定性。The electrolyte layer 230 may be composed of a gel-like material. Specifically, the electrolyte layer 230 may include a glue material, a plasticizer, a conductive ion, and a solvent. Thus, on the one hand, the electrolyte layer can serve as an ion channel, allowing ions in the ion storage layer to pass through the electrolyte layer into the electrochromic layer, react with the electrochromic material, and cause the electrochromic layer to change color. On the other hand, the electrolyte layer can be used as a spacer for the electrochromic layer and the ion storage layer, preventing ions in the ion storage layer from being de-doped and returned to the ion storage layer, thereby ensuring the stability of discoloration of the electrochromic layer. Specifically, taking an organic electrochromic material as an example, when a voltage is applied to the first transparent conductive layer 210 and the second transparent conductive layer 250, ions in the ion storage layer 240 enter the electrochromic layer 220 through the electrolyte layer 230, The ions in the ion storage layer 240 and the polymer in the electrochromic layer 220 undergo a redox reaction, that is, the doping or dedoping of the ions, and the polymer color after doping or dedoping changes, causing the electrochromism to change. The layer 220 appears in different colors. The electrolyte layer formed of a gel-like material has the advantages of high stability and long service life compared with a liquid electrolyte, and does not cause problems such as bubbling or leakage of the electrolyte, thereby further improving the service life of the casing. In order to further improve the discoloration stability of the electrochromic layer 220, the thickness of the electrolyte layer 230 may be designed to be slightly thicker. For example, the thickness of the electrolyte layer 230 may be 100-200 μm. Thereby, it is possible to further prevent ion doping from returning to the ion storage layer, and further improve the stability of discoloration of the electrochromic layer.

离子储存层240的厚度可以为纳米级别。由此，可以使电致变色层发生颜色变化。例如，离子储存层240中的离子可以呈现一定的蓝色，当离子储存层240的厚度较厚时，离子储存层240的颜色较深，在壳体不加电压时，离子储存层240的颜色便会透过电解质层230、电致变色层220、第一透明导电层210以及第一基板100，使得壳体呈现一定程度的蓝色，影响壳体的变色效果。由此，离子储存层的厚度可以根据上述两个条件进行合理设计，关于离子储存层的具体厚度值不受特别限制，只要能使电致变色层发生颜色变化以及不影响壳体的变色效果即可。The thickness of the ion storage layer 240 may be on the nanometer level. Thereby, a color change of the electrochromic layer can be performed. For example, the ions in the ion storage layer 240 may show a certain blue color. When the thickness of the ion storage layer 240 is thicker, the color of the ion storage layer 240 is darker. When no voltage is applied to the case, the color of the ion storage layer 240 is dark. It will pass through the electrolyte layer 230, the electrochromic layer 220, the first transparent conductive layer 210, and the first substrate 100, so that the shell appears a certain degree of blue, which affects the color changing effect of the shell. Therefore, the thickness of the ion storage layer can be reasonably designed according to the above two conditions, and the specific thickness value of the ion storage layer is not particularly limited, as long as the color of the electrochromic layer can be changed and the color changing effect of the shell is not affected can.

第二透明导电层250可以为氧化铟锡(ITO)或者纳米银，由此，第二透明导电层可以具有良好的导电性以及较高的透明度。当电致变色层220的颜色变为透明颜色时，电致变色单元200即为透明结构，由此，图案单元400的图案可以透过电致变色单元200呈现出来，也即是说，此时壳体呈现的图案或者颜色为图案单元400的图案或者颜色，形成一种隐藏式可调效果。第二透明导电层250可以具有较高的透明度，由此，第二透明导电层250的方阻也可以设计为小于20Ω。由此，一方面，该第二透明导电层具有良好的导电性能，方阻较小可以减少能量的损耗，且使变色时间控制在较短的范围内；另一方面，该第二透明导电层具有较高的透明度，在电致变色单元为透明结构时，可以较好的呈现图案单元的图案，形成一种隐藏式的可调效果。The second transparent conductive layer 250 may be indium tin oxide (ITO) or nano-silver. Therefore, the second transparent conductive layer 250 may have good conductivity and high transparency. When the color of the electrochromic layer 220 becomes a transparent color, the electrochromic unit 200 is a transparent structure. Therefore, the pattern of the pattern unit 400 can be displayed through the electrochromic unit 200, that is, at this time, The pattern or color presented by the casing is the pattern or color of the pattern unit 400, forming a hidden adjustable effect. The second transparent conductive layer 250 may have higher transparency, and thus, the square resistance of the second transparent conductive layer 250 may also be designed to be less than 20Ω. Therefore, on the one hand, the second transparent conductive layer has good conductivity, and the small square resistance can reduce energy loss, and control the discoloration time within a short range; on the other hand, the second transparent conductive layer It has high transparency. When the electrochromic unit is a transparent structure, the pattern of the pattern unit can be better presented to form a hidden adjustable effect.

或者，第二透明导电层也可以具有较低的透明度。需要说明的是，由于第二基板为设置有图案单元的基板，因此为了能令图案单元的图案、颜色、纹理等外观效果可以透过第二透明导电层250被用户观测到，因此需要令靠近第二基板一侧的导电层，即第二透明导电层250具有一定的透明度。因此，第二透明导电层250的透明度可以稍低于第一透明导电层210，只要可以令图案单元的外观效果，在第一基板一侧被肉眼观察到即可。也即是说，不必要求第二透明导电层250具有很高的透过率，因此可以进一步节约材料成本。Alternatively, the second transparent conductive layer may have lower transparency. It should be noted that, because the second substrate is a substrate provided with a pattern unit, in order to enable the appearance effects of the pattern unit such as the pattern, color, and texture to be observed by the user through the second transparent conductive layer 250, it is necessary to make the The conductive layer on the side of the second substrate, that is, the second transparent conductive layer 250 has a certain transparency. Therefore, the transparency of the second transparent conductive layer 250 may be slightly lower than that of the first transparent conductive layer 210 as long as the appearance effect of the pattern unit can be observed by the naked eye on the side of the first substrate. That is to say, it is not necessary to require the second transparent conductive layer 250 to have a high transmittance, so that the material cost can be further saved.

第二基板300可为透明的柔性基板，具体的，第二基板300可以为聚碳酸酯(PC)、聚甲基丙烯酸甲酯(PMMA)以及聚对苯二甲酸乙二醇酯(PET)的至少之一。由此，为图案单元提供支撑，并便于图案单元与电致变色单元的贴合。The second substrate 300 may be a transparent flexible substrate. Specifically, the second substrate 300 may be a polycarbonate (PC), polymethyl methacrylate (PMMA), or polyethylene terephthalate (PET). At least one. This provides support for the pattern unit and facilitates the bonding of the pattern unit and the electrochromic unit.

参考图3以及图4，第二基板300可以通过光学胶500贴合在电致变色单元200远离第一基板100的一侧。由此，可以简便的将设置有图案单元的第二基板与电致变色单元进行贴合。图案单元400可以包括：纹理印刷层410、光学镀膜层420以及油墨层430的至少之一。其中，油墨层430设置在图案单元400中远离电致变色单元200的一侧。由此，当电致变色单元为透明结构时，壳体可以呈现图案单元400中的图案或者颜色。油墨层430的透光率不大于30％，将油墨层430设置在图案单元400中远离电致变色单元200的一侧，可以遮挡电子设备中的元件，提高壳体的实用性。Referring to FIG. 3 and FIG. 4, the second substrate 300 may be attached to a side of the electrochromic unit 200 away from the first substrate 100 through an optical adhesive 500. Thereby, the second substrate provided with the pattern unit and the electrochromic unit can be simply bonded. The pattern unit 400 may include at least one of a texture printing layer 410, an optical coating layer 420, and an ink layer 430. The ink layer 430 is disposed on a side of the pattern unit 400 away from the electrochromic unit 200. Therefore, when the electrochromic unit has a transparent structure, the casing may present a pattern or color in the pattern unit 400. The light transmittance of the ink layer 430 is not greater than 30%. The ink layer 430 is disposed on the side of the pattern unit 400 away from the electrochromic unit 200, which can block components in the electronic device and improve the practicality of the casing.

上述图案单元400包括的具体结构不受特别限制，例如，可以含有上述结构(纹理印刷层410、光学镀膜层420以及油墨层430)中的一个，两个或是全部。当图案单元400包括多个层状结构时，多层结构之间的层叠顺序也不受特别限制，只要可以保证在第一基板100的一侧，多层结构中每一层的外观效果均可被肉眼观察到即可。例如，当图案单元400包括上述三层结构时，图案单元400可以包括依次层叠设置的纹理印刷层410、光学镀膜层420以及油墨层430。The specific structure included in the pattern unit 400 is not particularly limited. For example, the pattern unit 400 may include one, two, or all of the structures (the texture printing layer 410, the optical coating layer 420, and the ink layer 430). When the pattern unit 400 includes a plurality of layered structures, the stacking order between the multilayer structures is also not particularly limited, as long as the appearance effect of each layer in the multilayer structure can be guaranteed on one side of the first substrate 100 It can be observed by the naked eye. For example, when the pattern unit 400 includes the above-mentioned three-layer structure, the pattern unit 400 may include a texture printing layer 410, an optical coating layer 420, and an ink layer 430 which are sequentially stacked and arranged.

纹理印刷层410的纹理效果为可设计的纹理效果，本领域技术人员可以根据不同的效果设计不同的纹理。光学镀膜层420可以根据实际设计需求调节反光率以及颜色等，以获得需要的效果。The texture effect of the texture printing layer 410 is a designable texture effect, and those skilled in the art can design different textures according to different effects. The optical coating layer 420 can adjust the reflectance and color according to the actual design requirements to obtain the desired effect.

关于图案单元与光学胶的位置关系不受特别限制，本领域技术人员可以根据具体情况进行选择。例如，参考图3，图案单元400与光学胶500设置在第二基板300的异侧。换句话说，图案单元400与光学胶500可以分别设置在第二基板300的两侧。具体的，光学胶500设置在电致变色单元200远离第一基板100的一侧，第二基板300设置在光学胶500远离电致变色单元200的一侧，图案单元400设置在第二基板300远离光学胶500的一侧。或者，参考图4，图案单元400与光学胶500可以设置在第二基板300的同侧。具体的，光学胶500设置在电致变色单元200远离第一基板100的一侧，图案单元400设置在光学胶500远离电致变色单元200的一侧，第二基板300设置在图案单元400远离光学胶500的一侧。由此，可以将设置有图案单元的第二基板通过光学胶贴合在电致变色单元上。The positional relationship between the pattern unit and the optical adhesive is not particularly limited, and those skilled in the art may select according to specific situations. For example, referring to FIG. 3, the pattern unit 400 and the optical adhesive 500 are disposed on different sides of the second substrate 300. In other words, the pattern unit 400 and the optical adhesive 500 may be respectively disposed on two sides of the second substrate 300. Specifically, the optical adhesive 500 is disposed on a side of the electrochromic unit 200 away from the first substrate 100, the second substrate 300 is disposed on a side of the optical adhesive 500 away from the electrochromic unit 200, and the pattern unit 400 is disposed on the second substrate 300. The side far from the optical glue 500. Alternatively, referring to FIG. 4, the pattern unit 400 and the optical adhesive 500 may be disposed on the same side of the second substrate 300. Specifically, the optical adhesive 500 is disposed on the side of the electrochromic unit 200 away from the first substrate 100, the pattern unit 400 is disposed on the side of the optical adhesive 500 away from the electrochromic unit 200, and the second substrate 300 is disposed away from the pattern unit 400. One side of the optical glue 500. Thereby, the second substrate provided with the pattern unit can be bonded to the electrochromic unit by an optical adhesive.

关于第二基板与电致变色单元贴合的具体方式不受特别限制，例如，第二基板300可以通过光学胶500直接贴合在被密封的电致变色单元200上，贴合过程简单。可以将光学胶500绕设在电致变色单元200的***并密封，从而使得第二基板300贴合在电致变色单元200上。由此，可以利用光学胶密封电致变色单元并将第二基板贴合在电致变色单元上，使贴合更加牢固。The specific method of bonding the second substrate to the electrochromic unit is not particularly limited. For example, the second substrate 300 can be directly bonded to the sealed electrochromic unit 200 through the optical adhesive 500, and the bonding process is simple. The optical adhesive 500 may be wound around the periphery of the electrochromic unit 200 and sealed, so that the second substrate 300 is attached to the electrochromic unit 200. Therefore, the electrochromic unit can be sealed with an optical glue and the second substrate can be bonded to the electrochromic unit, so that the bonding is more firm.

参考图5，该壳体还可以包括：连接导线700，连接导线700与电致变色单元的电极层相连，也即是说，连接导线700与第一透明导电层210以及第二透明导电层250相连。由此，可以通过连接导线给第一透明导电层以及第二透明导电层施加电压，使电致变色层的颜色发生变化。Referring to FIG. 5, the housing may further include a connection wire 700 connected to the electrode layer of the electrochromic unit, that is, the connection wire 700 is connected to the first transparent conductive layer 210 and the second transparent conductive layer 250. Connected. Therefore, a voltage can be applied to the first transparent conductive layer and the second transparent conductive layer through the connection wires, so that the color of the electrochromic layer can be changed.

关于连接导线的具体材料以及其与第一透明导电层、第二透明导电层的连接方式不受特别限制，例如，参考图5，第一透明导电层210以及第二透明导电层250的至少之一，与连接导线700是通过同一次构图工艺形成的。具体的，与第一透明导电层210相连的连接导线700具有与第一透明导电层210相同的材料，与第一透明导电层210采用同一次构图工艺形成；与第二透明导电层250相连的连接导线700具有与第二透明导电层250相同的材料，与第二透明导电层250采用同一次构图工艺形成。由此，可以将连接导线做成与第一透明导电层或者第二透明导电层一体的结构，简化生产工艺。连接导电700与导电层采用同一构图工艺形成时，可以通过绝缘胶600密封电致变色层220、电解质层230以及离子储存层240，绝缘胶600设置在第一透明导电层210以及第二透明导电层250之间，并密封电致变色层220、电解质层230以及离子储存层240。具体地，未设置连接导线700一侧的绝缘胶600分别与第一透明导电层210、第二透明导电层250齐平，设置有连接导线700一侧的绝缘胶600分别与两个连接导线700齐平。换句话说，绝缘胶600可以覆盖位于第一透明导电层210、第二透明导电层250之间的层状结构的侧壁，而不覆盖第一透明导电层210、第二透明导电层250的侧壁，同时将于电极层一体的连接导线700暴露在外。由此，便于第二透明导电层以及与第二透明导电层相连的连接导线的设置。此时，可以利用光学胶直接将第二基板贴合在电致变色单元上。The specific material of the connection wire and the connection method with the first transparent conductive layer and the second transparent conductive layer are not particularly limited. For example, referring to FIG. 5, at least one of the first transparent conductive layer 210 and the second transparent conductive layer 250 is not limited. First, the connection pattern 700 is formed through the same patterning process. Specifically, the connecting wire 700 connected to the first transparent conductive layer 210 has the same material as the first transparent conductive layer 210, and is formed using the same patterning process as the first transparent conductive layer 210; The connecting wire 700 has the same material as the second transparent conductive layer 250 and is formed using the same patterning process as the second transparent conductive layer 250. Therefore, the connecting wire can be made into a structure integrated with the first transparent conductive layer or the second transparent conductive layer, thereby simplifying the production process. When the conductive 700 and the conductive layer are formed using the same patterning process, the electrochromic layer 220, the electrolyte layer 230, and the ion storage layer 240 can be sealed by an insulating adhesive 600. The insulating adhesive 600 is disposed on the first transparent conductive layer 210 and the second transparent conductive layer. Between the layers 250, the electrochromic layer 220, the electrolyte layer 230, and the ion storage layer 240 are sealed. Specifically, the insulating adhesive 600 on the side where the connecting wire 700 is not provided is flush with the first transparent conductive layer 210 and the second transparent conductive layer 250, respectively, and the insulating adhesive 600 on the side where the connecting wire 700 is provided and the two connecting wires 700 are respectively Flush. In other words, the insulating adhesive 600 may cover the sidewalls of the layered structure located between the first transparent conductive layer 210 and the second transparent conductive layer 250 without covering the first transparent conductive layer 210 and the second transparent conductive layer 250. At the same time, the side wall exposes the connecting wires 700 integrated with the electrode layer. This facilitates the arrangement of the second transparent conductive layer and the connection wires connected to the second transparent conductive layer. At this time, the second substrate can be directly bonded to the electrochromic unit by using an optical adhesive.

参考图6，连接导线700还可以为铜胶带。铜胶带的一端与电极层的端面相连，以实现铜胶带和电极层(第一透明导电层210、第二透明导电层250)的电连接。铜胶带的另一端向着壳体的外侧延伸，以实现和外电路的连接。由此，可以通过铜胶带实现电传导。绝缘胶600密封整个电致变色单元，铜胶带未与电极层相连的一端延伸至绝缘胶600外侧以便连接。由此，便于光学胶将第二基板直接贴合在电致变色单元上。或者，参考图7，光学胶500可以绕设在电致变色单元的***，并密封整个电致变色单元，光学胶500远离电致变色单元的一侧，具有与连接导线700相连的连接端口。也即是说，此时第二透明导电层250原理第一透明导电层210的一侧表面也被光学胶500覆盖。由此，可以通过光学胶密封电致变色单元，并将第二基板贴合在电致变色单元上。Referring to FIG. 6, the connecting wire 700 may also be a copper tape. One end of the copper tape is connected to the end surface of the electrode layer, so as to realize the electrical connection between the copper tape and the electrode layer (the first transparent conductive layer 210 and the second transparent conductive layer 250). The other end of the copper tape extends toward the outside of the case to achieve connection with an external circuit. Thereby, electrical conduction can be achieved by the copper tape. The insulating adhesive 600 seals the entire electrochromic unit. The end of the copper tape that is not connected to the electrode layer extends to the outside of the insulating adhesive 600 for connection. Therefore, it is convenient for the optical adhesive to directly adhere the second substrate to the electrochromic unit. Alternatively, referring to FIG. 7, the optical adhesive 500 may be wound around the periphery of the electrochromic unit and seal the entire electrochromic unit. The side of the optical adhesive 500 remote from the electrochromic unit has a connection port connected to the connection wire 700. That is, at this time, the surface of one side of the first transparent conductive layer 210 is also covered by the optical adhesive 500. Therefore, the electrochromic unit can be sealed with an optical adhesive, and the second substrate can be bonded to the electrochromic unit.

参考图8，连接导线700还可以为金属导线，金属导线穿越绝缘胶600并延伸至绝缘胶600远离电极层的一侧。由此，可以利用光学胶500直接将第二基板贴合在电致变色单元上。参考图9，光学胶500也可以绕设在电致变色单元的***，并密封整个电致变色单元，金属导线穿越光学胶500并延伸至光学胶500远离电极层的一侧，光学胶500远离电致变色单元的一侧，具有与连接导线700相连的连接端口。由此，可以通过光学胶密封电致变色单元，并将第二基板贴合在电致变色单元上。Referring to FIG. 8, the connecting wire 700 may also be a metal wire. The metal wire passes through the insulating glue 600 and extends to a side of the insulating glue 600 away from the electrode layer. Therefore, the second substrate can be directly bonded to the electrochromic unit by using the optical adhesive 500. Referring to FIG. 9, the optical adhesive 500 may also be wound around the periphery of the electrochromic unit and seal the entire electrochromic unit. The metal wire passes through the optical adhesive 500 and extends to the side of the optical adhesive 500 away from the electrode layer, and the optical adhesive 500 is away from One side of the electrochromic unit has a connection port connected to the connection wire 700. Therefore, the electrochromic unit can be sealed with an optical adhesive, and the second substrate can be bonded to the electrochromic unit.

Thereby, the first transparent conductive layer can be formed by a simple process. The electrochromic layer may be realized by electropolymerization. Specifically, the electropolymerization may be performed by a potentiostatic method or a galvanostatic method under a three-electrode system. Therefore, the shape of the first transparent conductive layer and the shape of the formed electrochromic layer can be easily controlled, thereby avoiding an additional trimming process, thereby simplifying the production process and reducing the production cost.

电解质层可以是通过丝网印刷的方式直接在电致变色层远离第一透明导电层的一侧形成的。如前所述，电解质层可以是由胶状材料形成的。由胶状材料形成的电解质层与液态电解质相比，具有高稳定性、寿命长等优点，产生鼓泡或者电解液外漏等不良现象的概率较低，从而可以进一步提高该壳体的使用寿命。The electrolyte layer may be directly formed on the side of the electrochromic layer away from the first transparent conductive layer by screen printing. As mentioned earlier, the electrolyte layer may be formed of a gel-like material.

The second transparent conductive layer may be formed by sputtering, so that the second transparent conductive layer is disposed on a side of the ion storage layer away from the electrolyte layer by a simple production process. Regarding the specific temperature of the sputtering, those skilled in the art can select it according to conventional operations.

S300：在第二基板上设置图案单元S300: Setting a pattern unit on the second substrate

在该步骤中，在第二基板上设置图案单元。例如，图案单元可以是通过以下步骤形成的：在第二基板上，形成纹理印刷层、光学镀膜层以及油墨层的至少之一。油墨层设置在图案单元中远离电致变色单元的一侧。由此，当电致变色单元为透明状态时，壳体可以显示为图案单元的图案或者颜色。In this step, a pattern unit is provided on the second substrate. For example, the pattern unit may be formed by forming at least one of a texture printing layer, an optical coating layer, and an ink layer on the second substrate. The ink layer is disposed on a side of the pattern unit remote from the electrochromic unit. Therefore, when the electrochromic unit is in a transparent state, the casing can be displayed as a pattern or color of the pattern unit.
