Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ultra-thin glass technology, and more specifically, it relates to an ultra-thin glass cover plate without light and shadow. Background Technology
[0002] With the rapid development of consumer electronics, glass is widely used in the electronics industry. The market has increasingly stringent requirements for the thickness of protective glass for touchscreen covers, making ultra-thin glass a key development trend. Ultra-thin glass covers are mainly used in foldable phones, foldable laptops, and various wearable electronic devices. Ultra-thin glass (UTG) refers to flexible glass with a thickness of less than 100 μm. Due to its high transparency, stability, and impact resistance, UTG is widely used in various electronic industries. Its bendable characteristics represent a significant milestone for the foldable display industry, making it a crucial player in the field of foldable flexible covers after CPI covers. With the increasing demand for diversified consumer products, UTG loses some impact strength due to its thinner plate thickness. Therefore, a pattern with thicker edges and a thinner middle is designed. However, conventional patterns have too obvious edges and corners, resulting in very obvious light and shadow on the product to the naked eye. Consequently, when conventional pattern 3D glass is used as a mobile phone cover, the pattern area exhibits poor light and shadow due to the LED matrix, resulting in low utilization of pattern 3D folding products in actual use. Currently, the pattern designs of 3D pattern folding covers on the market are usually elongated or round. However, these elongated and rounded designs result in very sharp edges and corners. During the tempering process, the edges of the pattern cannot release stress, leading to a risk of breakage. Furthermore, after tempering, the stress concentration at the edges of the elongated or rounded designs becomes even more pronounced during ball and pen drops, potentially causing the glass to break at the edges. This prevents the 3D pattern glass cover from leveraging its high strength advantage. Compared to conventional UTG products, it does not demonstrate a significant advantage; instead, the lack of light and shadow coverage results in only a slight increase in strength, negatively impacting market perception of 3D pattern products.
[0003] The prior art includes a technology entitled "Cover Panel Assembly, Display Module, and Method for Manufacturing a Display Module" with publication (announcement) number "CN120220542A". This technology relates to a cover panel assembly, a display module, and a method for manufacturing a display module. The cover panel assembly is applied to the light-emitting side of a display panel. The feature is that it includes a cover layer, which is an ultra-thin glass without light reflection. The cover layer includes a first surface and a second surface disposed opposite to each other. After the cover panel assembly is assembled with the display panel, the first surface is located on the side of the cover layer away from the display panel. A groove is provided on a first area on the first surface corresponding to the bending area of the display panel, and the edge of the groove smoothly transitions with the first surface on which it is located.
[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a light-reflection-free ultrathin glass cover that is simple in structure, can achieve the purpose of no light shadow in the pattern area of the glass cover, and at the same time improves the impact resistance of the product, in order to overcome the shortcomings of the existing technology.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is an ultra-thin glass cover plate without light and shadow, including a glass cover plate body, the glass cover plate body includes a first thick edge and a second thick edge, and an intermediate thinning pattern area is provided between the first thick edge and the second thick edge. The intermediate thinning pattern area includes multiple spacing grooves and multiple raised ribs, and the raised ribs are configured with an arc-shaped cross-section.
[0007] Multiple spacing grooves and multiple raised ribs are arranged alternately, and each raised rib has a spacing groove on each side.
[0008] The bottom surface of the spacing groove is either a concave structure or a planar structure.
[0009] There is a spacing groove near the first thick edge and another spacing groove near the second thick edge.
[0010] The inner surface of the first thick edge is a first arc-shaped surface, and the inner surface of the second thick edge is a second arc-shaped surface.
[0011] Multiple raised ribs extend from the front of the glass cover body to the rear of the glass cover body, and the multiple raised ribs are arranged in parallel.
[0012] The width of the convex rib is smaller than the width of the spacing groove.
[0013] The convex ribs, spacing grooves, and glass cover plate body are an integral structure.
[0014] The working principle and beneficial effects of this utility model are as follows: The ultra-thin, shadow-free glass cover of this invention modifies the structure of the central thinned pattern area of the glass cover body, making the central thinned pattern area include multiple spacing grooves and multiple raised ribs, with the raised ribs shaped like goose-eyes. The principle of achieving shadowlessness through the raised ribs is that when light passes through the pattern, it undergoes an irregular reflection. Because the spacing between the grooves of the raised ribs is narrow, the reflected light does not immediately return to the human eye, but undergoes another diffuse reflection through the surrounding goose-eye-shaped raised ribs. Through the effects of reflection and diffuse reflection, the light and shadow in the pattern area are weakened under any light source, achieving the goal of shadowlessness in the pattern area. At the same time, because the overall shape of the goose-eye is smoother, during the subsequent tempering process, there is no stress concentration phenomenon at the corners of the pattern area as in the prior art. Instead, the glass better releases stress during impact and bending, thereby significantly improving the product's bending and impact resistance, achieving high strength, high impact, and high bending resistance.

Detailed Implementation
[0016] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 -Appendix Figure 2As shown, this utility model is an ultra-thin glass cover plate without light and shadow, including a glass cover plate body 1. The glass cover plate body 1 includes a first thick edge portion 2 and a second thick edge portion 3. A middle thinning pattern region 4 is provided between the first thick edge portion 2 and the second thick edge portion 3. The middle thinning pattern region 4 includes multiple spacing grooves 5 and multiple raised ribs 6, and the raised ribs 6 are configured with an arc-shaped cross-section. An improved technical solution is proposed for the above structure. In the structural setting, the structure of the middle thinning pattern region 4 of the glass cover plate body 1 is changed so that the middle thinning pattern region 4 includes multiple spacing grooves 5 and multiple raised ribs 6, and the raised ribs 6 are shaped like goose eyes. The principle behind achieving shadowless illumination through the raised ribs 6 is that light passing through the pattern undergoes an irregular reflection. Because the spacing of the grooves 5 between the raised ribs 6 is narrow, the reflected light does not immediately return to the eye. Instead, it undergoes another diffuse reflection through the surrounding goose-eye-shaped raised ribs 6. Through this reflection and diffuse reflection, the shadow in the pattern area is softened under any light source, achieving shadowless illumination in the pattern area. Simultaneously, because the overall shape of the goose-eye is smoother, during subsequent tempering, there is no stress concentration at the corners of the pattern area as seen in existing technologies. Instead, the glass can better release stress during impact and bending, significantly improving the product's bending and impact resistance, achieving high strength, high impact resistance, and high bending resistance. The shadowless ultra-thin glass cover of this invention has a simple structure, achieving shadowless illumination in the pattern area of the glass cover while improving the product's impact resistance.
[0017] Multiple spacing grooves 5 and multiple raised ribs 6 are arranged alternately, with a spacing groove 5 on each side of each raised rib 6. The number and size of the spacing grooves 5 and multiple raised ribs 6 are determined according to the specific glass size and pattern requirements.
[0018] The bottom surface of the spacing groove 5 is either concave or planar. There is one spacing groove 5 near the first thick edge 2 and another near the second thick edge 3. The inner surface of the first thick edge 2 is a first arc-shaped surface 7, and the inner surface of the second thick edge 3 is a second arc-shaped surface 8. Multiple raised ribs 6 extend from the front to the rear of the glass cover body 1, and are arranged in parallel. The width of the raised ribs 6 is less than the width of the spacing groove 5. The raised ribs 6, the spacing grooves 5, and the glass cover body 1 are an integral structure.
[0019] The ultra-thin glass cover of this invention features a specific goose-eye shaped rib design 6, resulting in a smoother transition. This goose-eye-like shape allows light of any wavelength to pass through the pattern through multiple refractions, cleverly avoiding shadows caused by reflected light and achieving a shadow-free pattern area. Furthermore, the goose-eye shaped rib design prevents stress concentration in the pattern area, unlike existing solutions with elongated or circular ribs. To ensure high strength, transition areas are typically designed with smoother curves, evenly dissipating stress concentration and giving the tempered, patterned folded product extremely high impact resistance. This glass cover possesses excellent optical properties, high strength, and high bending resistance, effectively improving overall quality.
[0020] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
