Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0059] refer to Figure 1 An appliance panel assembly according to a first aspect of an embodiment of the present invention is described.

[0060] refer to Figure 1 As shown, the electrical panel assembly of the embodiment of the present invention mainly includes a base plate 100 and a display board, wherein the base plate 100 is provided with a display window 110 penetrating the base plate 100; and a display board 120 is provided at the bottom of the display window 110; the display board includes a transparent substrate 210 and a fabric layer 220 connected in sequence starting from the base plate; a photochromic material layer 230 is provided on the fabric layer 220 at a position corresponding to the display window 110; and the display board is arranged on a side of the base plate 100 away from the display board 120.

[0061] It is understandable that in the electrical panel assembly of the present invention, the bottom plate 100 is connected to the electrical appliance, and the display panel 120 has a display function. When the display panel 120 displays letters or numbers, the letters or numbers emit light, and the light passes through the display window 110, and then passes through the transparent substrate 210 to reach the fabric layer 220. The fabric layer 220 is provided with a photochromic material layer 230 at a position corresponding to the display window 110. When the light irradiates the photochromic material layer 230, the color of the photochromic material layer 230 changes, thereby displaying the same letters or numbers as those displayed by the display panel 120, thereby realizing the display function of the characters. When the display panel 120 is turned off, the light disappears, and the photochromic material layer 230 returns to its original color.

[0062] It can also be understood that the electrical panel assembly of the present invention does not need to be hollowed out to expose the display window 110, which simplifies the processing technology of the transparent substrate 210 and the fabric layer 220 in the display board and reduces the processing cost.

[0063] It should be noted that in the electrical panel assembly of the present invention, the photochromic material layer 230 can realize photochromism by using the light emitted by the display panel 120 without the need for ultraviolet light irradiation, and the surrounding materials are not prone to aging.

[0064] It should also be noted that in the electrical panel assembly of the present invention, the photochromic material layer 230 is non-toxic, will not cause harm to the human body, has a high degree of safety, and can meet relevant export standards.

[0065] It is further explained that in the electrical panel assembly of the present invention, the display board is arranged on the side of the base plate 100 away from the display board 120. Since the display board 120 may be energized, the display board 120 is arranged below the base plate 100. When the display board is removed, the display board 120 will not be directly touched, which complies with safety regulations and improves safety performance.

[0066] It should be understood that the display panel 120 includes LED light groups, and the LED light groups are arranged in a double figure-8 shape.

[0067] LED light groups are composed of LED lights. LED lights are made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. They are a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes. When electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes. They are used as indicator lights in circuits and instruments, or as text or digital displays. Among them, gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light.

[0068] It is understandable that, compared with other light sources, the light from the LED light group is more focused and can more easily change the color of the photochromic material layer 230 .

[0069] It should be noted that in the electrical panel assembly of the present invention, the bottom plate 100 is magnetically connected to the display board, and the bottom plate 100 is magnetically connected to the display board, which is quick and convenient to disassemble, replace and clean the display board.

[0070] It should be noted that a first magnetic sheet 240 is disposed on a surface of the transparent substrate 210 facing the bottom plate 100 .

[0071] The first magnetic sheet 240 is an iron sheet, or a magnet sheet. The thickness of the first magnetic sheet 240 is 0.3 mm to 1.0 mm.

[0072] It can be understood that the second magnetic sheet 130 is provided on the side of the bottom plate 100 facing the electrical appliance, and the positioning groove 140 opposite to the second magnetic sheet 130 is provided on the side of the bottom plate 100 facing away from the electrical appliance, and the positioning groove 140 is adapted to the first magnetic sheet 240. The second magnetic sheet 130 is provided on the side of the bottom plate 100 facing the electrical appliance, and the second magnetic sheet 130 provides magnetism to adsorb and fix the first magnetic sheet 240 in the positioning groove 140, thereby realizing the magnetic connection of the display board.

[0073] Understandably, reference Figure 2 As shown, a positioning groove 140 can also be provided on the side of the bottom plate 100 facing away from the electrical appliance, and the second magnetic sheet 130 can be directly provided in the positioning groove 140, and the positioning groove 140 is adapted to the first magnetic sheet 240. Since the second magnetic sheet 130 is provided in the positioning groove 140, the second magnetic sheet 130 can provide magnetism to adsorb and fix the first magnetic sheet 240 in the positioning groove 140, thereby realizing the magnetic connection of the display board.

[0074] It is understandable that the first magnetic sheet 240 cooperates with the second magnetic sheet 130. The first magnetic sheet 240 may be actively magnetically attracted, and the second magnetic sheet 130 may be passively magnetically attracted; or the first magnetic sheet 240 may be passively magnetically attracted, and the second magnetic sheet 130 may be actively magnetically attracted.

[0075] It should be noted that the transparent substrate 210 is a PC transparent plate, a PP transparent plate, a GPPS transparent plate, a PET transparent plate, a PMMA transparent plate, an AS transparent plate or an MBS transparent plate.

[0076] Among the above transparent plate materials, PC has high impact strength and can be used in many engineering application fields.

[0077] PP has acceptable transparency and impact strength and is often used in medical tubes and transparent daily necessities.

[0078] GPPS has good rigidity and is easy to process, but its disadvantage is that it is relatively brittle.

[0079] PET has good high temperature resistance.

[0080] PMMA has high light transmittance and is mainly used for processing plexiglass and handicrafts.

[0081] The strength of AS is between GPPS and MBS, and it is mostly used in stationery, toys, and packaging products.

[0082] MBS is mainly used for transparent parts of electrical appliances, daily necessities and office equipment.

[0083] It is further explained that the thickness of the transparent substrate 210 is 0.3 mm to 1.0 mm. The thickness of the transparent substrate 210 is 0.3 mm to 1.0 mm, which is conducive to the light passing through the display panel 120 and can also provide sufficient strength support for the fabric layer 220.

[0084] It is further explained that the photochromic material layer 230 is in the shape of a double 8. It can be understood that the photochromic material layer 230 is in the shape of a double 8, which can highlight the color change effect and make the character display more obvious.

[0085] It should be noted that the photochromic material layer 230 is a molybdenum oxide / titanium dioxide composite layer, a phosphomolybdic acid / ethyl cellulose composite layer, a phosphomolybdic acid / polyvinyl pyrrolidone composite layer or a heteropolyacid / SiO2 / ZnFe2O4 composite layer.

[0086] It should be noted that the preparation method of the photochromic material layer 230 is: prepare the photochromic material, apply the photochromic material on the fabric layer 220, and then dry it to obtain the photochromic material layer 230.

[0087] The preparation method of the molybdenum oxide / titanium dioxide composite, one of the photochromic materials, specifically comprises the following steps:

[0088] At room temperature, 3 mol / L HCl aqueous solution was slowly added dropwise to 400 mL aqueous solution containing 5.8013 g Na2MoO4 under stirring until pH < 1. The solution was aged at room temperature for three weeks.

[0089] 7.2 mL of isopropyl titanate was slowly added dropwise to 400 mL of 0.5 mol / L HCl aqueous solution, and the solution was stirred continuously until it became clear and transparent, and then aged at room temperature for three weeks;

[0090] The aged molybdenum oxide sol of different volumes is added dropwise into the titanium dioxide sol under stirring conditions to make the molar ratio of MoO3 / TiO2 be (2-10):1, thereby obtaining a molybdenum oxide / titanium dioxide composite.

[0091] For the molybdenum oxide / titanium dioxide composite, one of the photochromic materials, the Mo-O-Ti bond formed at the interface of molybdenum oxide and titanium dioxide makes the material have the characteristic of visible light color change response. Under the irradiation of the light emitted by the LED light group, the electrons are excited to jump from the valence band of titanium dioxide to the conduction band of molybdenum oxide, thus showing a color change response on a macro scale. When the light irradiation disappears, the excited electrons return to normal, and the material returns to its original color.

[0092] The preparation method of the second photochromic material, the phosphomolybdic acid / ethyl cellulose composite, specifically comprises the following steps:

[0093] At room temperature, 0.36 g of phosphomolybdic acid was dissolved in 5 mL of ethanol to obtain a phosphomolybdic acid ethanol solution;

[0098] Prepare a polyvinyl pyrrolidone ethanol solution with a concentration of 0.01 g / mL, and the specific preparation method is to weigh 0.10 g of polyvinyl pyrrolidone and dissolve it in 10 mL of ethanol;

[0099] Under stirring conditions, 0.1 mL of phosphomolybdic acid ethanol solution was added dropwise into the polyvinyl pyrrolidone ethanol solution. After sufficient stirring and reaction for 2 h at room temperature, a light yellow transparent solution, namely, the phosphomolybdic acid / polyvinyl pyrrolidone complex, was obtained.

[0100] The preparation method of the heteropoly acid / SiO2 / ZnFe2O4 composite of the fourth photochromic material specifically comprises the following steps:

[0101] 0.808gFe(NO3)3·9H2O and 0.595gZn(NO3)·6H2O were accurately weighed and dissolved in 30mL ethylene glycol, and 15mmol sodium acetate was added to the solution. The mixture was stirred for 30min at room temperature, and then the mixed solution was transferred into a 50mL stainless steel reactor with a polytetrafluoroethylene liner. The mixture was reacted at 180°C for 12h and naturally cooled to room temperature. The brown precipitate was separated by centrifugation, ultrasonically washed with anhydrous ethanol and deionized water for several times, and then dried in a vacuum drying oven at 60°C for 4h to obtain ZnFe2O4 ferrite nanoparticles.

[0102] 22.5 mL of ethyl orthosilicate was dissolved in 23.5 mL of anhydrous ethanol under constant stirring, and then a mixed solution of 9.2 mL of anhydrous ethanol, 1.8 mL of distilled water and 5 mL of propylene glycol was added dropwise, and stirring was continued for 5 h. 0.4 mL of concentrated hydrochloric acid was added dropwise for hydrolysis to prepare a colorless transparent sol, which was aged overnight to obtain a silica sol.

[0103] Weigh 0.36g of phosphomolybdic acid and dissolve it in 5mL of ethanol, which is called solution A. Add 0.5mL of ZnFe2O4 ferrite nanoparticle solution to solution A under stirring, which is called solution B. Take 1mL of the mixed solution of A and B and slowly add it to the silica solution. After stirring and reacting for 2h, a transparent composite solution is obtained, which is the heteropoly acid / SiO2 / ZnFe2O4 composite.
