Description

Technical Field

[0001] This utility model relates to the field of coated cover technology, and in particular to a temperature-sensitive coated cover. Background Technology

[0002] With the widespread adoption of technological products and consumers' increasing demands for quality, traditional glass covers can no longer meet the market's multiple needs for durability, aesthetics, and functionality, especially in areas such as smartphones, tablets, smart wearable devices, and automotive display covers.

[0003] For example, Chinese Patent (Publication No. CN208572159U) discloses a cover plate structure and a mobile terminal. The cover plate structure includes a transparent cover plate; a coating structure located in a preset area on the surface of the transparent cover plate, the coating structure including multiple coating units, the area of ​​each coating unit arranged along a first direction gradually increasing; and an ink layer located on the side of the transparent cover plate opposite to the coating structure, the color of the ink layer being different from the color of the coating structure, and the color of the ink layer being white. This makes the preset area of ​​the cover plate structure present a gradient from the color of the ink layer to the color formed by the superposition of the ink layer and the coating units, thereby achieving a gradient effect and improving the user experience.

[0004] However, its main feature of creating gradient color effects is rather ordinary. After a period of use, its novelty for consumers gradually diminishes, and it can only provide a simple pattern display effect, resulting in a rather monotonous user experience. Especially in the field of high-end smart devices, it cannot effectively attract consumers in the current market environment. Utility Model Content

[0005] Based on this, it is necessary to provide a temperature-sensitive coated cover plate to address the aforementioned technical problems. The cover plate coating layer design of this application, through scientific layering structure and material selection, not only significantly improves the physical properties and service life of the cover plate, but also endows it with a unique temperature sensing function, meeting the pursuit of high quality and multifunctionality in modern technological products.

[0016] As a preferred embodiment of the temperature-changing coated cover provided by this utility model, the coating layer is provided with three layers, which include a wear-resistant layer, a temperature-controlling layer and a corrosion-resistant layer in sequence. The wear-resistant layer is disposed on the front side of the cover body, the temperature-controlling layer is disposed on the front side of the wear-resistant layer, and the corrosion-resistant layer is disposed on the front side of the temperature-controlling layer.

[0030] As described in the background section, after a period of use, the novelty of the device gradually decreases, and it can only provide a simple graphic display effect, resulting in a relatively monotonous user experience. This is especially true in the field of high-end smart devices, where it cannot effectively attract consumers in the existing market environment.

[0031] To solve this technical problem, this utility model provides a temperature-sensitive coated cover plate, which is applied to coated cover plates.

[0032] For details, please refer to Figures 1-4 A thermochromic coated cover plate includes a cover plate body 1, a thermochromic layer 2, a protective layer 3, and a coating layer. The back surface of the cover plate body 1 is composed of a color-changing area 7 and a blank area 8.

The protective layer 3 corresponds to the position of the thermochromic layer 2 and is disposed on the side of the thermochromic layer 2 away from the cover plate body 1. The coating layer is disposed on the front surface of the cover plate body 1.

[0033] This utility model provides a thermochromic coated cover plate. Using the cover plate body 1 as the base layer, it ensures the transparency and structural support of the base, improving the aesthetics and practicality of the cover plate. The coating layer protects the front of the cover plate body 1, increasing its strength and wear resistance, making it more durable and adaptable to various environments.

[0034] In summary, the cover plate coating design of this application, through its scientific layered structure and material selection, not only significantly improves the physical properties and service life of the cover plate, but also endows it with a unique temperature sensing function, meeting the pursuit of high quality and multifunctionality in modern technological products.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1

[0039] Please refer to Figures 1-2 A thermochromic coated cover plate includes a cover plate body 1, a thermochromic layer 2, a protective layer 3, and a coating layer. The cover plate body 1 is a glass cover plate, which serves as a substrate, providing structural support and transparency, allowing the color emitted by the thermochromic layer 2 to be better transmitted. The back area of ​​the cover plate body 1 consists of a color-changing area 7 and a blank area 8. The thermochromic layer 2 is disposed on the back of the cover plate body 1 and is located at the color-changing area 7. The thermochromic layer 2 can change color according to different temperature changes. The shape of the color-changing area 7 is set according to requirements, so that when the thermochromic layer 2 emits color at a specific temperature, the shape of the color-changing area 7 corresponding to the color is displayed, thereby providing users with an intuitive prompt effect. The thermochromic layer 2 is a thermochromic ink layer that can change color according to temperature changes, providing a visual temperature indication. The thermochromic layer 2 is screen-printed onto the back of the cover plate body 1 and placed at the color-changing area 7.

[0040] It is worth mentioning that you should refer to Figure 1 The protective layer 3 corresponds to the thermochromic layer 2. The protective layer 3 is located on the side of the thermochromic layer 2 away from the cover plate body 1. The protective layer 3 is a titanium nitride protective layer with a thickness of 8-12 nanometers. It protects the thermochromic ink layer below from scratches, wear and chemical corrosion. It directly covers the thermochromic ink layer.

[0041] In addition, the coating layer is applied to the front of the cover plate body 1, which can protect the front of the cover plate body 1, improve the strength and wear resistance of the cover plate, and make the cover plate more durable and adaptable to various environments. The coating layer consists of three layers, namely a wear-resistant layer 4, a temperature control layer 5, and a corrosion-resistant layer 6. The wear-resistant layer 4 is applied to the front of the cover plate body 1. The wear-resistant layer 4 is a magnesium silicate layer with a thickness of 12-22 micrometers. Magnesium silicate has good physical and chemical stability, which can enhance the structural strength of the cover plate body 1, making it more durable and less prone to damage. The temperature control layer... 5 is set on the front of the wear-resistant layer 4. The temperature control layer 5 is an aluminum silicate layer with a thickness of 12-22 micrometers. The low thermal conductivity of aluminum silicate helps to regulate the thermal conductivity of the cover plate body 1, so that it can better control the heat transfer in application. The corrosion-resistant layer 6 is set on the front of the temperature control layer 5. The corrosion-resistant layer 6 is a calcium silicate layer with a thickness of 15-25 micrometers. Calcium silicate has a certain degree of corrosion resistance and can resist the erosion of some corrosive substances. Adding calcium silicate to the coating layer can improve the corrosion resistance of the film layer and extend its service life.

[0042] By introducing a three-layer coating of magnesium silicate, aluminum silicate, and calcium silicate, the structural strength, thermal conductivity, and corrosion resistance are enhanced, making the cover plate more durable and adaptable to various environments. In particular, the magnesium silicate layer is tightly bonded to the glass substrate, improving the overall adhesion and stability; the aluminum silicate layer optimizes thermal management with its low thermal conductivity; and the calcium silicate layer effectively resists the erosion of corrosive substances.

[0043] Example 2

[0044] The thermochromic coating cover plate provided in Embodiment 1 is further optimized, specifically, as follows: Figures 3-4 As shown, the color-changing area 7 is set as a reminder pattern, and the thermochromic layer 2 covers the reminder pattern, as shown. Figure 3 Different shapes and patterns of color display areas 7 can be set. When the thermochromic layer 2 is screen-printed onto the color display area 7, the cover can emit corresponding colors when the ambient temperature and equipment temperature change, and display the shape or pattern set in the color display area 7, which can quickly and intuitively remind the user. It can also be used as an interactive pattern with the ambient temperature, allowing the user to intuitively understand the temperature status of the environment or equipment.

[0045] In addition, multiple color-changing grooves 9 are etched on the temperature control layer 5. These grooves 9 are evenly arranged on the front side of the temperature control layer 5. The temperature control layer 5 is an aluminum silicate layer with a thickness of 12-22 micrometers. The low thermal conductivity of aluminum silicate helps to adjust the thermal conductivity of the cover plate body 1, enabling better control of heat transfer during application. By etching color-changing grooves 9 on the aluminum silicate layer, when the equipment temperature and the ambient temperature are transferred to the thermosensitive color-changing layer 2 through the temperature control layer 5, the temperature transfer effect is different between the etched and unetched parts of the temperature control layer 5. This results in different colors being displayed at the corresponding locations on the thermosensitive color-changing layer 2, allowing the thermosensitive color-changing layer 2 to emit different colors under the same environment. This further increases the product's interest and appeal, meeting the needs of complex application scenarios.

[0046] The working principle of the temperature-sensitive coated cover provided by this utility model is as follows: Through a carefully designed layered structure, both performance and aesthetics are improved. First, the cover body 1 serves as the base layer, ensuring the transparency and structural support of the foundation. Subsequently, three coating layers—magnesium silicate, aluminum silicate, and calcium silicate—are introduced, which respectively enhance structural strength, adjust thermal conductivity, and improve corrosion resistance, making the cover more durable and adaptable to various environments. In particular, the magnesium silicate layer bonds tightly to the glass substrate, improving overall adhesion and stability; the aluminum silicate layer optimizes thermal management with its low thermal conductivity; and the calcium silicate layer effectively resists the erosion of corrosive substances.
