[0057] Positive and negative electrodes 5, which are placed at both ends of the cable 4, for connecting external power for power supply;
[0058] The external power connected to the positive and negative electrodes 5 includes a controller, which is used to control the brightness of the electro-optic coating on the surface of the light-emitting layer 3 by adjusting the current size;

[0074] Specifically, the electro-optic coating structure device in the present application is formed by sequentially compounding the back plate layer 1, the medium layer 2, the light-emitting layer 3 and the transparent conductive layer 6 to form an overall coating structure. The back plate layer 1 is composed of acrylic resin and copper powder, which provides high conductivity and stability, and its role is to provide basic support for the coating and at the same time form the conductive path of the positive and negative electrodes to ensure that the coating has excellent conductivity with a resistance value ≤10Ω. The medium layer 2 improves the insulation effect by the distribution of titanium white powder, prevents short circuit of the positive and negative electrodes, and at the same time optimizes the optical performance of the light-emitting layer to make the light efficiency uniform and stable. The light-emitting layer 3 is composed of light-emitting particles and acrylic resin, which uses an external electric field to drive the light-emitting particles to produce bright and uniform light efficiency, and realizes electric field driving and light-emitting protection through the transparent conductive layer 6, while maintaining the brightness output of the light-emitting layer and the durability of the coating.

[0075] Example two: please refer to the attached Figure 3 An electro-optic coating spraying method, characterized in that it comprises the following steps:
[0076] S1, preparing the back plate layer 1: mix and stir the back plate paint and the diluent at a ratio of 1:0.5, filter the impurities with a funnel, and spray the object surface using a 1.3mm caliber spray gun, and bake and cure;
[0077] S2, preparing the medium layer 2: mix the acrylic resin, titanium white powder and diluent well to obtain the medium paint, spray the medium paint on the positive light-emitting area, and then perform curing treatment;
[0078] S3, preparing the light-emitting layer 3: mix the acrylic resin, light-emitting particles and diluent to obtain the light-emitting paint, spray the light-emitting paint on the medium layer at a low air pressure level, check the uniformity with a violet light lamp, and cure with a hot air gun;
[0079] S4, preparing the transparent conductive layer 6: mix the acrylic resin, transparent conductive powder and diluent to obtain the iron door conductive liquid, then filter the light-emitting paint with a filter screen, and finally spray the transparent conductive paint with a spray gun and perform curing treatment;
[0080] The baking condition of the back plate layer 1 is 65℃-70℃, which lasts for 13min-17min, and the resistance value of the back plate paint layer is within 10Ω;
[0081] The medium layer 2 is sprayed at an interval of 2-3 minutes each time, 3-5 times, and after the edges are polished with 2000# sandpaper, a hot air gun is used for curing at 65°C or above for 9-12 minutes;
[0082] The preparation ratio of the luminescent layer 3 surface luminescent paint is:
[0083] The volume ratio of alcohol to transparent conductive powder is 1:4, and the weight ratio is 1:3;
[0084] After spraying, baking at 65°C is performed for 4-6 minutes.
[0085] Specifically, the spraying method of the electro-optic coating structure includes the layer-by-layer spraying and curing process of the back plate layer 1, the medium layer 2, the luminescent layer 3, and the transparent conductive layer 6. First, the back plate paint is diluted at a ratio of 1:0.5, impurities are filtered through a hopper, a 1.3mm caliber spray gun is used for low-pressure wet spraying to uniformly cover the substrate, and a high-conductive coating is formed after baking at 65-70°C for 13-17 minutes. Then, the medium paint is sprayed in the positive luminescent area, and a smooth insulating surface is gradually formed by multiple spraying 3-5 times at an interval of 2-3 minutes, while the edges are polished with 2000# sandpaper and cured with a hot air gun at 65°C or above for 9-12 minutes. Next, the luminescent paint is low-pressure sprayed on the surface of the medium layer, and after checking the uniformity with a purple light, the hot air gun is used for curing to ensure that the luminescent particles are evenly distributed and the coating is flawless. Finally, the transparent conductive paint is filtered and sprayed on the surface of the luminescent layer, and baking at 65°C for 4-6 minutes is performed, and the transparent conductive layer ensures the formation of the conductive network and the transparent protection of the light effect. The spraying method has a clear process flow, ensuring the performance consistency and efficient luminescent characteristics of the coating.
[0086] Example Three: An electro-optic coating structure device application, the electro-optic coating device is applied to the following scenarios:
[0087] It is used for safety indication of bicycles driving at night;
[0088] It is used for eye-catching LOGO of carbon fiber bicycles.
[0089] Specifically, by spraying the back plate layer 1, the medium layer 2, the luminescent layer 3, and the transparent conductive layer 6 on the surface of the vehicle body, a multifunctional composite coating is formed, which realizes self-luminescence effect when the bicycle is ridden at night, greatly improves the safety of riding, and also gives the vehicle body a unique visual aesthetic, making the appearance more modern and attractive.
[0090] In the carbon fiber bicycle industry, lightweight is one of the key factors to improve performance. Although traditional light-emitting strips can provide certain night safety functions, their weight and energy consumption seriously affect the speed and riding efficiency of the vehicle body. The electro-optic coating of the present application applied to the surface of the vehicle body 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 a more efficient and comfortable riding experience.
[0091] In addition, the unique nature of electro-optic 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 light-emitting coating. The light-emitting layer can respond to an external electric field to emit bright and uniform light, making the vehicle more easily recognized 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 individual needs of different consumers for appearance, making the appearance of carbon fiber bicycles more eye-catching and standing out in the market.
[0092] The electro-optic paint also has significant durability advantages. Due to its special coating technology, it can resist wear and impact during daily riding and still maintain good light-emitting effect in harsh weather conditions. Compared with traditional light strips or light-emitting devices, electro-optic coatings have a longer service life and do not need frequent maintenance or replacement, which not only reduces the long-term maintenance cost of bicycles, but also saves time and money, significantly improving the user's convenience and economy.
[0093] In addition, the environmental advantages of electro-optic paint are particularly prominent. As a special coating that does not contain any harmful substances, it does not pollute the environment during production, use and disposal, fully meeting the needs of modern consumers for environmentally friendly products. This environmentally friendly feature provides strong support for its widespread application in the green travel and low-carbon economy trends.
[0094] In summary, the application of electro-optic coatings brings a comprehensive upgrade in performance, design, safety and environmental protection to the carbon fiber bicycle industry. With the continuous development of technology, the application scenarios of electro-optic coatings in the bicycle field will further expand, becoming an important driving force for technological innovation in the bicycle industry.
