Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to the attached Figure 1 -Attached Figure 2 , an embodiment of the present invention provides an electro-optical coating structure device, comprising: Backplane layer 1, which serves as the base material of the device and is used to provide a stable foundation for the entire electro-optical coating; A dielectric layer 2, which is disposed on the top of the backplane layer 1 and is used to isolate and protect the electro-optical coating; The light-emitting layer 3 is arranged on the top of the dielectric layer 2 and is used to fill a special material that emits light in response to changes in the electric field; A transparent conductive layer 6 is disposed on the top of the dielectric layer 2 and is used to conduct current and maintain the transparency of the coating on the surface of the light-emitting layer 3; The cable 4 is arranged inside the back plate layer 1 and is used to energize the electro-optical coating on the surface of the light-emitting layer 3; Positive and negative electrodes 5, which are arranged at both ends of the cable 4 and are used to connect to external power for power supply; The external power connected to the positive and negative electrodes 5 includes a controller, which is used to control the brightness of the electro-optical coating on the surface of the light-emitting layer 3 by adjusting the current; The backplane layer 1 includes the following components in weight percentage: Acrylic resin: 65wt%-75wt%; Copper powder: 25wt%-35wt%; The dielectric layer 2 includes the following components in weight percentage: Acrylic resin 56wt%-75wt%; Titanium dioxide: 20wt%-24wt%; Diluent: 5wt%-20wt%; The light-emitting layer 3 includes the following components in weight percentage: Acrylic resin: 70wt%-75wt%; Luminescent particles: 10wt%-15wt%; Diluent: 10wt%-20wt%; The transparent conductive layer 6 includes the following components in weight percentage: Acrylic resin: 60wt%-65wt%; Transparent conductive powder: 15wt%-20wt%; Diluent: 15wt%-25wt%.

[0020] Specifically, the electro-optical coating structure device in the present invention is formed by compounding the backplane layer 1, the dielectric layer 2, the luminescent layer 3 and the transparent conductive layer 6 in sequence to form an overall coating structure. The backplane layer 1 is composed of acrylic resin and copper powder, which provides high conductivity and stability. Its function is to provide basic support for the coating, and at the same time form a conductive path for the positive and negative electrodes to ensure that the coating has excellent conductive performance and a resistance value of ≤10Ω. The dielectric layer 2 improves the insulation effect through the distribution of titanium dioxide to prevent short circuits between the positive and negative electrodes, and at the same time optimizes the optical properties of the luminescent layer to make the light effect uniform and stable. The luminescent layer 3 is composed of luminescent particles and acrylic resin, and uses an external electric field to drive the luminescent particles to produce bright and uniform light effects, and realizes electric field driving and luminescent protection through the transparent conductive layer 6, while maintaining the brightness output of the luminescent layer and the durability of the coating. The cable 4 and the positive and negative electrodes 5 adjust the current through an external controller to achieve dynamic regulation of the luminous brightness, which is widely used in scenes requiring electro-optical display.

[0021] Example 2: Please refer to the attached Figure 3 , a method for spraying electro-optical coating, characterized in that it comprises the following steps: S1. Prepare backboard layer 1: mix backboard paint and thinner in a ratio of 1:0.5, filter impurities with a funnel, spray on the surface of the object with a 1.3 mm caliber spray gun, and bake to cure; S2, preparing dielectric layer 2: fully shaking acrylic resin, titanium dioxide and diluent to obtain dielectric paint, spraying the dielectric paint on the positive electrode light-emitting area, and then performing a curing treatment; S3, preparing luminous layer 3: mixing acrylic resin, luminous particles and diluent to obtain luminous paint, spraying the luminous paint onto the dielectric layer under low pressure, checking uniformity with a purple light, and curing with a hot air gun; S4, preparing a transparent conductive layer 6: mixing acrylic resin, transparent conductive powder and diluent to obtain a conductive liquid for iron door, then filtering with a filter to obtain a luminous paint, and finally spraying the transparent conductive paint with a spray gun and curing it; The baking condition of the backplane layer 1 is 65°C to 70°C for 13min to 17min, and the resistance value of the backplane paint layer is within 10Ω; When spraying the dielectric layer 2, the interval between each spraying is 2 to 3 minutes, and spraying is performed 3 to 5 times. After grinding the edge with 2000# sandpaper, use a hot air gun above 65℃ to cure for 9 to 12 minutes; The formulation ratio of the luminous paint on the surface of the luminous layer 3 is: The volume ratio of alcohol to transparent conductive powder is 1:4, and the weight ratio is 1:3; After spraying, bake at 65°C for 4 to 6 minutes.

[0022] Specifically, the spraying method of the electro-optical coating structure includes a layer-by-layer spraying and curing process of the backplane layer 1, the dielectric layer 2, the luminescent layer 3 and the transparent conductive layer 6. First, after the backplane paint is diluted in a ratio of 1:0.5, the impurities are filtered through a funnel, and a 1.3mm caliber spray gun is used to wet-spray at low pressure to evenly cover the substrate, and baked at 65°C to 70°C for 13min to 17min to form a highly conductive coating. Subsequently, the dielectric paint is sprayed on the positive luminous area, and a smooth insulating surface is gradually formed by spraying 3 to 5 times with an interval of 2min to 3min. At the same time, the edges are polished with 2000# sandpaper and cured with a hot air gun at above 65°C for 9min to 12min. Next, the luminous paint is sprayed on the surface of the dielectric layer at low pressure. After checking the uniformity with a purple light lamp, it is cured with a hot air gun to ensure that the luminous particles are evenly distributed and the coating is flawless. Finally, the transparent conductive paint is sprayed on the surface of the luminous layer after filtering and baked at 65°C for 4 to 6 minutes. The transparent conductive layer ensures the formation of the conductive network and transparent protection of the bright effect. The spraying method has a clear process flow and ensures the performance consistency and efficient luminous characteristics of the coating.

[0023] Embodiment 3: An application of an electro-optical coating structure device, the electro-optical coating device is applied in the following scenarios: It is used as a safety indicator for riding bicycles at night; It is used for eye-catching LOGO on carbon fiber bicycles.

[0024] Specifically, a multifunctional composite coating is formed by spraying a back panel layer 1, a dielectric layer 2, a luminous layer 3 and a transparent conductive layer 6 on the surface of the bicycle body, so that the bicycle can achieve a self-luminous effect when riding at night, which not only greatly improves the riding safety, but also gives the bicycle body a unique visual beauty, making the appearance more modern and attractive.

[0025] In the carbon fiber bicycle industry, lightweighting is one of the keys to improving performance. Although traditional luminous light strips can provide certain nighttime safety functions, their weight and energy consumption seriously affect the speed and riding efficiency of the vehicle body. The electro-optical coating of the present invention is applied to the surface of the vehicle body, which can effectively replace the traditional light strip design. The weight of the coating is reduced by more than 98% compared with the traditional light strip, and there is almost no significant increase in the weight of the vehicle body. This extreme lightweight feature is particularly suitable for bicycle enthusiasts who pursue extreme performance, providing them with a more efficient and comfortable riding experience.

[0026] In addition, the uniqueness of electro-optical coating technology not only reduces the weight of the vehicle body, but also provides additional safety for night riding through the high brightness and uniformity of the luminous coating. The luminous layer can respond to the external electric field and emit bright and uniform light, making the vehicle easier to identify in low-light environments and improving the safety factor of the rider. At the same time, the diversified design of the coating can meet the personalized needs of different consumers for appearance, making the appearance of carbon fiber bicycles more eye-catching and standing out in the market.

[0027] Electro-optical paint also has significant durability advantages. Because it uses special coating technology, it can resist the wear and impact of daily riding and maintain good luminous effects in adverse weather conditions. Compared with traditional light strips or light-emitting devices, electro-optical paint has a longer service life and does not require frequent maintenance or replacement, which not only reduces the maintenance cost of long-term use of bicycles, but also saves time and money, significantly improving the convenience and economy of use for users.

[0028] In addition, electro-optical paint also has outstanding advantages in environmental protection. As a special paint that does not contain any harmful substances, it will not pollute the environment during production, use and disposal, which fully meets the needs of modern consumers for environmentally friendly products. This environmental protection feature provides strong support for its wide application in the trend of green travel and low-carbon economy.

[0029] Overall, the application of electro-optical coatings has brought comprehensive upgrades in performance, design, safety and environmental protection to the carbon fiber bicycle industry. With the continuous development of technology, the application scenarios of electro-optical coatings in the bicycle field will be further expanded, becoming an important boost to promote technological innovation in the bicycle industry.
