[0016] (Three) beneficial effects

[0017] One of the above technical solutions has the following advantages or beneficial effects:

[0018] To address the shortcomings of existing technologies, traditional cover glass, made of multiple layers of glass, while using tempered glass to increase impact resistance, offers only a limited and negligible increase in impact resistance between the inner and outer layers. This leads to the common problem of both inner and outer glass being damaged by an impact when the outer layer breaks. Furthermore, uneven lateral force can easily cause the glass to shatter, resulting in damage. By incorporating an acrylic layer between the first and second glass layers, heat resistance is ensured while increasing the impact resistance of the inner layer. This reduces the likelihood of the inner layer breaking along with the outer layer, facilitating subsequent repairs and minimizing simultaneous damage to both layers. It also increases the likelihood of the equipment remaining usable after an impact. Additionally, an anti-reflective coating is applied between the acrylic layer and the glass layers to reduce reflected light and stray light, resulting in better light transmittance. Moreover, the glass sides are equipped with inner and outer protective frames and double-layered buffers, all made of light-transmitting materials, which reduces lateral impact while maintaining light transmittance.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0029] Example 1:

[0030] This utility model provides a shockproof cover glass: its structure includes a light-shielding layer 1, a first glass layer 2, a second glass layer 3, a first anti-reflective film 4, an acrylic layer 5, a second anti-reflective layer 6, a first protective layer 7, a second protective layer 8, a protective outer frame 9, a first buffer layer 10, a protective inner frame 11, and a second buffer layer 12. The acrylic layer 5 is coated with the first anti-reflective film 4 and the second anti-reflective layer 6 on both sides. The side of the first anti-reflective film 4 away from the acrylic layer 5 is bonded to the second glass layer 3, and the side of the second anti-reflective layer 6 away from the acrylic layer 5 is bonded to the first glass layer 2. The first glass layer 2 and the second glass layer 3 are bonded together. The outer periphery of the combination of glass layer 3, first antireflective film 4, acrylic layer 5 and second antireflective layer 6 is covered and bonded with a protective inner frame 11 by a second buffer layer 12. The outer periphery of the protective inner frame 11 is covered and bonded with a protective outer frame 9 by a first buffer layer 10. A first protective layer 7 is bonded to the top of the first glass layer 2. A light-shielding layer 1 is bonded to the top of the combination of the first glass layer 2, protective outer frame 9, first buffer layer 10, protective inner frame 11 and second buffer layer 12. The light-shielding layer 1 is arranged around the outer periphery of the first protective layer 7. A second protective layer 8 is bonded to the top of the first protective layer 7 and the light-shielding layer 1.

[0031] Both the first glass layer 2 and the second glass layer 3 are tempered glass.

[0032] In this process, both the first antireflective film 4 and the second protective layer 8 are AR films.

[0033] The acrylic layer 5 is made of acrylic.

[0034] The first protective layer 7 is silica glass or plastic film.

[0035] The second protective layer 8 is an AR film, an AG film, or an AF film.

[0036] The outer protective frame 9 is made of tempered glass or silica glass, and the inner protective frame 11 is made of tempered glass, silica glass, or acrylic.

[0037] The first buffer layer 10 and the second buffer layer 12 are both made of optical adhesive.

[0038] When subjected to a positive impact, when the impact force passes through the first protective layer 7 and the second protective layer 8 and impacts the first glass layer 2, the impact force received by the first glass layer 2 can be partially dispersed to the second buffer layer 12 for buffering, reducing the impact force. When the impact force exceeds the first glass layer 2 and causes damage to the first glass layer 2, it will be blocked by the acrylic layer 5. Through the high impact resistance of the acrylic layer 5, the impact force can be greatly prevented from continuing to impact and damage the second glass layer 3, increasing the impact resistance of the inner layer. At the same time, it reduces the damage of the inner layer when the outer layer breaks, which facilitates subsequent maintenance and reduces the situation of simultaneous damage to the inner and outer layers, increasing the possibility that the equipment can still be used after being impacted. In addition, an anti-reflective film is coated between the acrylic layer 5 and the first glass layer 2 and the second glass layer 3, which can reduce reflected light and stray light in the system, making the product's light transmittance better.

[0039] When subjected to a side impact, the side impact force is first blocked by the outer protective frame 9, and then the impact force is transmitted to the first buffer layer 10 for buffer absorption, and then transmitted to the inner protective frame 11 and the first buffer layer 10 for buffer absorption, which can greatly reduce the side impact force.

[0040] Meanwhile, the outer protective frame 9, the first buffer layer 10, the inner protective frame 11, and the second buffer layer 12 are all made of light-transmitting materials to ensure light transmittance.

[0041] Example 2: Compared with Example 1, the inner surface of the protective outer frame 9 in this example is a uniform wave-shaped structure, and the outer surface of the protective inner frame 11 is a wave-shaped structure that matches the inner surface of the protective outer frame 9. When subjected to lateral impact force, the impact force will diffuse in multiple directions due to the wave-shaped curved surface, and then be transmitted to the protective inner frame 11 and the second buffer layer 12 for buffering and absorption, resulting in better buffering performance. The rest of the structure and effect remain unchanged.

[0042] Example 3: Compared to Example 2, the inner surface of the protective outer frame 9 in this example has a uniform wave-shaped structure on all four sides, and the four corners of the inner surface of the protective outer frame 9 have arc-shaped grooves. The outer surface of the protective inner frame 11 has a wave-shaped structure on all four sides that matches the inner surface of the protective outer frame 9. The four corners of the outer surface of the protective inner frame 11 are convex arcs. When subjected to lateral impact, the impact force on all four sides will diffuse in multiple directions due to the wave-shaped curved surface, and then be transmitted to the protective inner frame 11 and the second buffer layer 12 for buffering and absorption. The four corners are buffered with a large arc surface of overall arc, which increases the diffusion of the impact force on all four sides, increases the buffering performance of the four corners, and reduces the possibility of the four corners being damaged by impact. The rest of the structure and effect remain unchanged.
