Technical Field

[0001] This utility model relates to the field of cover plate technology, and more specifically, to a glass cover plate. Background Technology

[0002] With advancements in technology and ever-increasing consumer demands for the quality of electronic products, traditional glass covers are no longer sufficient to meet the comprehensive requirements of the high-end market for light transmittance, abrasion resistance, corrosion resistance, and aesthetics. Especially in the field of portable electronic devices such as smartphones and tablets, covers not only need to protect delicate internal components from external damage but also need to possess an attractive appearance and enhance the user experience. Therefore, developing a cover coating structure that integrates high light transmittance, anti-reflection, abrasion resistance, corrosion resistance, and interactive features has become a current research hotspot and urgent need in the industry. Utility Model Content

[0003] The purpose of this invention is to provide a glass cover plate that aims to solve some of the technical problems existing in the prior art.

[0004] Specifically, the technical solution of this utility model is as follows: a glass cover plate is proposed, including a first glass substrate and a second glass substrate stacked together. The first glass substrate and the second glass substrate are fastened and fixed by a soft plastic ring. The soft plastic ring includes a left ring part and a right ring part. A locking part is provided on the left ring part, and a fastening part is provided on the right ring part. The locking part and the fastening part cooperate with each other to fasten and fix the left ring part and the right ring part.

[0005] The front side of the first glass substrate is coated with a titanium diboride coating layer, a tin bronze alloy coating layer and a neodymium oxide coating layer from the inside to the outside.

[0006] The non-viewing area on the back of the first glass substrate is coated with a thermochromic ink screen printing layer, a polyester resin layer and a chromium plating layer in sequence from the inside to the outside.

[0007] As a preferred technical solution, the second glass substrate is physically tempered glass.

[0008] As a preferred technical solution, the thickness of the neodymium oxide coating layer is 50-100 nanometers; the thickness of the tin bronze alloy coating layer is 20-30 nanometers; and the thickness of the titanium diboride coating layer is 15-25 nanometers.

[0009] As a preferred technical solution, the thickness of the thermochromic ink screen printing layer is 8-12 micrometers; the thickness of the polyester resin layer is 20-30 micrometers; and the thickness of the chromium plating layer is 10-20 nanometers.

[0010] As a preferred technical solution, the thickness of the neodymium oxide coating layer is preferably 70-90 nanometers, and the average transmittance in the visible light band of 380-780nm is ≥92%, the surface roughness Ra≤3nm, and the neodymium oxide layer is deposited by magnetron sputtering process.

[0011] As a preferred technical solution, the tin bronze alloy layer is a film layer produced by ion beam assisted deposition.

[0012] As a preferred technical solution, the thermochromic ink screen printing layer contains thermochromic microcapsules with a particle size distribution of 5-20μm, a color-changing temperature threshold of 28-35℃, and a color change response time of ≤5 seconds.

[0014] As a preferred technical solution, the chromium plating layer is prepared by a multi-arc ion plating process, and the surface of the chromium plating layer is subjected to plasma nitriding treatment to form a CrN transition layer with a thickness of 2-5 nm.

[0015] As a preferred technical solution, the first glass substrate is chemically strengthened aluminosilicate glass.

[0016] The beneficial effects of this utility model are: the new glass cover plate includes two layers of glass substrates stacked on top of each other and fixed by a soft plastic ring. With such a cover plate mechanism, when the first glass substrate on the upper layer is damaged, the second glass substrate can protect the display screen.

[0017] This new cover plate improves light transmittance and anti-reflection, making products brighter and clearer. Neodymium oxide, tin bronze alloy, titanium diboride, and a chromium layer work together to provide excellent wear resistance and hardness, effectively protecting the glass surface from scratches. Thermochromic ink adds fun and interactivity to the product, while screen printing allows for customization of various patterns, enhancing the product's visual appeal. A polyester resin layer and a chromium layer act as an inner protective layer, effectively preventing scratches on the ink layer and ensuring the durability and aesthetics of the ink pattern.

[0018] The selection and combination of materials for each layer not only enhances the physical properties of the cover plate, but also improves its overall stability and durability, meeting the high performance requirements of high-end electronic products for the cover plate.

[0035] like Figure 4-6 The soft plastic ring includes a left ring and a right ring. The left ring has a locking component, and the right ring has a fastening component. The locking and fastening components cooperate to fasten and fix the left and right rings together. During the fastening process, the locking component is pressed downward (or inward) by compression deformation, and the fastening component, after deformation, passes through the through hole on the locking component to complete the fastening.

Therefore, when the first glass substrate is damaged, the second glass substrate can protect the display screen below.

[0039] Preferably, the thickness of the neodymium oxide coating is 50-100 nanometers; the thickness of the tin bronze alloy coating is 20-30 nanometers; and the thickness of the titanium diboride coating is 15-25 nanometers.

[0040] Preferably, the thickness of the thermochromic ink screen printing layer is 8-12 micrometers; the thickness of the polyester resin layer is 20-30 micrometers; and the thickness of the chromium plating layer is 10-20 nanometers.

[0041] Preferably, the thickness of the neodymium oxide coating layer is 70-90 nanometers, and the average transmittance in the visible light band of 380-780nm is ≥92%, and the surface roughness Ra≤3nm. The neodymium oxide layer is deposited by magnetron sputtering.

[0042] Preferably, the tin bronze alloy layer is a film layer produced using an ion beam assisted deposition process.

[0043] Preferably, the thermochromic ink screen printing layer contains thermochromic microcapsules with a particle size distribution of 5-20μm, a color-changing temperature threshold of 28-35℃, and a color change response time of ≤5 seconds.

[0044] Preferably, the polyester resin layer is composed of modified polyethylene terephthalate, with a glass transition temperature (Tg) of 75-85℃ and an elongation at break ≥150%. This effectively protects the ink layer.

[0045] Preferably, the chromium plating layer is prepared by a multi-arc ion plating process, and the surface of the chromium plating layer is subjected to plasma nitriding treatment to form a CrN transition layer with a thickness of 2-5 nm.

[0046] Preferably, the first glass substrate is chemically strengthened aluminosilicate glass. This glass has high strength and hardness.
