The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0034] Example 1, please refer to Figure 1This invention provides a cover plate with improved weather resistance and chemical corrosion resistance, comprising a glass substrate 1 and, from bottom to top, an aluminum nitride layer 11, a neodymium oxide layer 12, and a polysulfonated fluorine layer 13 sequentially disposed on the upper surface of the glass substrate 1.

The middle layer is neodymium oxide, a rare earth oxide with unique optical properties such as high refractive index and high transmittance. By adjusting the thickness and doping of the neodymium oxide layer 12, specific optical effects such as anti-reflection, anti-reflection, or color adjustment can be achieved. The top layer uses polysulfonated fluorine, a fluoropolymer with excellent weather resistance, chemical corrosion resistance, and a low coefficient of friction, effectively protecting the coating layer and improving the lubricity of the glass surface, reducing fingerprints and stains. This three-layer glass cover coating technology not only has excellent adhesion and protective performance but also good weather resistance, chemical corrosion resistance, and specific optical properties, meeting different application requirements and providing a new solution for the development of high-performance glass covers.
[0035] Through this three-layer structure design, the composite coating layer of this patent achieves a comprehensive improvement in the performance of the glass cover. The thermal and chemical stability of the aluminum nitride bottom layer ensures the stability of the coating layer under high temperature and chemical corrosion environments; the optical transparency and hardness of the silica intermediate layer improve the optical performance and abrasion resistance of the glass cover; and the hydrophobicity and oleophobicity of the polyhexafluoropropylene top layer enhance the stain resistance and durability of the glass cover. In addition, the entire coating layer also has good adhesion and thermal stability, ensuring a tight bond and long-term stability between the coating layer and the glass substrate 1.
[0036] In practical applications, the thickness and process parameters of each layer of the composite coating layer of this patent can be adjusted according to specific needs to achieve optimal performance. At the same time, strict process control and quality control standards ensure the quality and reliability of the coating layer, meeting the requirements of various high-end applications.
[0037] Example 2, please refer to Figure 2 This utility model also provides a handheld communication device, which includes a cover plate as described above to improve weather resistance and chemical corrosion resistance, a TFT module 2 is disposed below the glass substrate 1, and an FPC 3 is led out from the TFT module 2.
[0038] Please see Figure 3Furthermore, the FPC3 includes a body 31, a reinforcing plate 32, and a connector 33. The reinforcing plate 32 is fixed to the upper surface of the end of the body 31. Both ends of the reinforcing plate 32 have outwardly extending fixing parts 34. Both fixing parts 34 extend beyond the edge of the body 31. The lower surface of both fixing parts 34 is fixed with a first strong magnet 35. The connector 33 is located below the body 31. Two second strong magnets 36, corresponding to the two first strong magnets 35, are fixed on the connector 33. Because a reinforcing plate 32 is fixed to the upper surface of the main body 31, and a first strong magnetic block 35 is fixed to both ends of the reinforcing plate 32, and two second strong magnetic blocks 36 corresponding to the two first strong magnetic blocks 35 are fixed to the connector 33, when the main body 31 and the connector 33 are installed, as long as the two ends of the main body 31 are brought close to the connector 33, the first strong magnetic blocks 35 at both ends of the main body 31 and the second strong magnetic blocks 36 at both ends of the connector 33 will attract each other, approach and fix themselves, and the main body 31 and the connector 33 can achieve automatic alignment and tight connection. This assembly structure of FPC3 has few assembly steps and only requires Assembly can be achieved simply by bringing the body 31 close to the connector 33. The assembly efficiency of FPC3 can be greatly improved, and automated assembly of FPC3 and connector 33 can be easily realized. The fewer assembly steps, the lower the probability of defective FPC3 products during assembly. This avoids the situation where the assembled product cannot work properly due to poor assembly, thereby avoiding product malfunction and reducing the product defect rate. As a result, the production and manufacturing costs of FPC3 are greatly reduced, which in turn improves the product competitiveness of FPC3 and meets the increasing quality requirements of enterprises.
[0039] Furthermore, two grooves 37 are provided on the connector 33, and two second strong magnets 36 are fixed in the two grooves 37 respectively, so that the body 31 and the connector 33 fit more tightly, improve the reliability of assembly, thereby significantly reducing the production and manufacturing cost of FPC3, and thus improving the product competitiveness of FPC3, so as to meet the growing quality requirements of enterprises.
[0040] Furthermore, the edge of the groove 37 is chamfered, preferably a right angle or a rounded corner, so that when the first strong magnetic block 35 approaches the second strong magnetic block 36, it can accurately fall into the groove 37 under the guidance of the chamfer, improving the accuracy and reliability of assembly, thereby significantly reducing the production and manufacturing cost of FPC3 and thus improving the product competitiveness of FPC3.
[0041] Furthermore, the outer dimensions of the second strong magnetic block 36 are larger than those of the first strong magnetic block 35, and the outer dimensions of the groove 37 correspond to those of the first strong magnetic block 35 and the second strong magnetic block 36, so that the second strong magnetic block 36 can be firmly fixed in the groove 37. Even if the attraction force of the first strong magnetic block 35 is large, it will not pull the second strong magnetic block 36 out, thereby improving the reliability of assembly. This significantly reduces the production and manufacturing cost of FPC3, thereby improving the product competitiveness of FPC3 and meeting the growing quality requirements of enterprises.
[0042] Furthermore, the depth of the groove 37 is equal to the sum of the thicknesses of the first strong magnetic block 35 and the second strong magnetic block 36, so that the assembly of the body 31 and the connector 33 can be smooth and seamless. More preferably, a buffer pad can be provided on the contact surface between the body 31 and the connector 33, and a buffer groove corresponding to the buffer pad can be formed on the connector 33 to provide cushioning during assembly and prevent damage to the body 31 or the connector 33. Even more preferably, the buffer pad is a rubber pad, which is effective, low-cost, and cost-effective.
[0043] Furthermore, both the first strong magnetic block 35 and the second strong magnetic block 36 are made of neodymium iron boron strong magnets. Neodymium iron boron strong magnets have mature technology and high cost performance.
[0044] Furthermore, the first strong magnetic block 35 and the second strong magnetic block 36 are different colors so that workers can distinguish between them during installation. In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
