Description

Technical Field

[0001] This utility model relates to the field of electronic components, and in particular to an ink protective cover. Background Technology

[0002] Currently, the outermost surface of a display screen or touchscreen is equipped with a protective cover to protect it from scratches. A border ink is silkscreened on the outer perimeter of the back of the protective cover to shield the non-display areas of the display screen or touchscreen. During assembly, the area of ​​the protective cover with the border ink needs to be adhered and fixed to the casing.

[0003] However, if the border ink is bumped by external objects during assembly, resulting in surface scratches, the adhesion of the adhesive to the border ink will decrease, leading to the protective cover not being firmly bonded to the machine casing, thus affecting the stability of the entire machine during use. Utility Model Content

[0016] Furthermore, the ink protective cover also includes a high-hardness, corrosion-resistant, and wear-resistant coating, which is disposed on the front side of the cover body and corresponds to the light-transmitting area and the ink area.

[0017] Furthermore, the high-hardness, corrosion-resistant, and wear-resistant coating includes at least one of an iron-molybdenum carbide coating, an iron-titanium alloy coating, and a titanium-aluminum-vanadium alloy coating.

[0027] Example 1

[0028] like Figure 1 and 2 As shown, an ink protective cover plate includes:

[0029] The cover plate body 1 includes a light-transmitting area 11 and an ink area 12, with the ink area 12 surrounding the periphery of the light-transmitting area 11.

[0030] A border ink layer 2 is disposed on the back side of the cover plate body 1 and corresponds to the ink area 12;

[0031] Self-healing coating 3 is disposed on the back side of the border ink.

[0032] The ink protective cover of this utility model provides a self-healing coating 3 on the back of the ink layer 2 of the frame. The self-healing coating 3 protects the ink layer 2 of the frame and repairs the surface scratches when the cover is bumped by external objects, thus ensuring the adhesion of the adhesive and avoiding the problem of poor adhesion to the machine casing.

[0033] The self-healing coating 3 has a certain degree of elasticity, which can absorb part of the impact force when it is hit by an external object, thereby reducing the impact force. When the impact force is large, the self-healing coating 3 will offset the impact force by breaking the molecular chain to form surface scratches. The broken molecular chains can be repaired by microcapsules or relinked by dynamic covalent bonds, thereby repairing the surface scratches.

[0034] In this embodiment, the self-healing coating 3 is a cerium nitrate microcapsule coating, an epoxy resin microcapsule coating, a dynamic polyurethane / polyurea coating, an N-hydroxyphthalimide ester coating, an acid-responsive hydrazone / epoxy resin coating, a light-controlled hydrazone coating, an epoxy-disulfide composite coating, or a rubber-based disulfide coating, etc., and the thickness of the self-healing coating 3 is 10-40 μm.

[0035] Preferably, the border ink layer 2 includes a thermochromic ink layer 21, which can sense the ambient temperature and undergo reversible color changes according to the ambient temperature, so that the ink protective cover has a more personalized appearance.

[0036] Preferably, the border ink layer 2 further includes a constant color ink layer 22, which is disposed on the side of the thermochromic ink layer 21 away from the cover plate body 1. Through the cooperation of the thermochromic ink layer 21 and the constant color ink layer 22, and by combining the thermochromic properties of the thermochromic ink layer 21, the border ink layer 2 enables the ink-protected cover plate to have a richer range of appearance colors.

[0037] Specifically, the thermochromic ink layer 21 is colorless at room temperature, so that the ink protective cover has an appearance color consistent with the constant color ink layer 22; the thermochromic ink layer 21 is colored at temperatures below or above room temperature, so that the ink protective cover has an appearance color consistent with the color-changing thermochromic ink layer 21, or the color-changing thermochromic ink layer 21 and the constant color ink layer 22 are mixed.

[0038] In this embodiment, the thermochromic ink layer 21 is a bisphenol A crystal violet lactone ink layer with a thickness of 6-9 μm; the color-changing ink layer 22 is a conventional colored ink, such as black ink, red ink or blue ink, with a thickness of 8-12 μm.

[0039] Example 2

[0040] As an optimized solution of Embodiment 1, in this embodiment, the ink protective cover plate further includes a high-hardness, corrosion-resistant and wear-resistant coating layer 4, which is disposed on the front side of the cover plate body 1 and corresponds to the light-transmitting area 11 and the ink area 12.

[0041] The high-hardness, corrosion-resistant, and wear-resistant coating 4 includes at least one of the following: iron-molybdenum carbide coating 41, iron-titanium alloy coating 42, and titanium-aluminum-vanadium alloy coating 43.

[0042] The iron-molybdenum carbide coating 41, the iron-titanium alloy coating 42, and the titanium-aluminum-vanadium alloy coating 43 all possess high hardness, resistance to acid and alkali corrosion, and abrasion resistance, which can enhance the mechanical properties and chemical stability of the front side of the ink protective cover plate, further improving its protective effect.

[0043] In this embodiment, the ink protective cover plate simultaneously has an iron-molybdenum carbide coating 41, an iron-titanium alloy coating 42, and a titanium-aluminum-vanadium alloy coating 43. These coatings are sequentially formed on the front surface of the cover plate body 1 using methods such as magnetron sputtering, vacuum evaporation, or chemical vapor deposition. The thickness of the iron-molybdenum carbide coating 41 is 70-90 nm, the thickness of the iron-titanium alloy coating 42 is 60-80 nm, and the thickness of the iron-molybdenum carbide coating 41 is 50-70 nm.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
