Description

Technical Field

[0001] This utility model relates to the field of mobile phone protection, specifically an ultra-thin and tough mobile phone screen protector. Background Technology

[0002] A screen protector is a thin film used to protect the screen of a mobile phone, usually made of plastic or glass. Its main function is to prevent scratches, fingerprints, oil stains, and other physical damage. Some screen protectors also offer features such as blue light protection, anti-reflection, and anti-glare. Common screen protectors are mainly divided into two types: plastic films and glass films. Plastic films are thinner and softer, offering a comfortable feel but poorer scratch resistance. Glass films are much thicker than plastic films but offer better scratch and drop resistance.

[0003] Existing glass-based screen protectors are prone to shattering when a phone is dropped, or when the screen protector is broken by impacts to the edges or corners. This is because the glass structure is relatively dense and has poor deformation capacity. In particular, the force applied to the sides and corners of the glass screen protector will directly lead to the glass breaking and the screen protector being damaged. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] An ultra-thin and tough mobile phone screen protector includes a film 1. An adhesive layer 7 is coated on the bonding surface of the film 1. A transparent plastic film 2 covers the adhesive layer 7. A dark-colored extension section 8 is provided on one side of the transparent plastic film 2. The film 1 and the transparent plastic film 2 are mounted on an upper plastic frame 3. The upper plastic frame 3 has a film groove 5 corresponding to the film 1. The film 1 is placed in the film groove 5 and adheres to the inner wall of the film groove 5. The transparent plastic film 2 adheres to the side of the upper plastic frame 3. A lower plastic frame 4 is provided on the side of the upper plastic frame 3 adjacent to the film 1. A mobile phone placement slot 6 is provided on the lower plastic frame 4. The mobile phone can be placed in the mobile phone placement slot 6, and the upper plastic frame 3 and the lower plastic frame 4 can be aligned vertically. Then, the operator can pull the dark-colored extension section 8 to detach the transparent plastic film 2 completely. The adhesive layer 7 adheres the mobile phone to the film 1, completing the installation. A through hole is provided on the lower plastic frame 4 to facilitate the separation of the film 1 and the lower plastic frame 4 after the film 1 is installed.

[0027] Furthermore, the four corners of the diaphragm 1 are fitted with anti-crack protective sleeves 9. The anti-crack protective sleeves 9 have inner rounded corners 10, and the four corners of the diaphragm 1 have outer rounded corners 11. The inner rounded corners 10 are larger than the outer rounded corners 11, and the outer rounded corners 11 are inserted into the inner rounded corners 10. The inner rounded corners 10 on the anti-crack protective sleeves 9 must be larger than the outer rounded corners 11 on the diaphragm 1. The gap in between can be filled with adhesive. The shape of the anti-crack protective sleeves 9 is also semi-circular arched. The arched structure provides strong stability and can disperse force. The fragile four corners are protected by the anti-crack protective sleeves 9. If impacted, the anti-crack protective sleeves 9 and the filling adhesive will absorb the vibration potential energy, preventing the diaphragm 1 from being subjected to large impact forces, thus achieving anti-crack protection and improving toughness and strength.

[0028] Furthermore, the diaphragm 1 includes a high-crystal glass layer 12, a blue light blocking layer 13, and a privacy layer 14. The blue light blocking layer 13 is located on one side of the high-crystal glass layer 12, and the privacy layer 14 is located on the side of the blue light blocking layer 13 opposite to the high-crystal glass layer 12. The high-crystal glass layer 12 is thinner and has a better feel than ordinary tempered glass. The blue light blocking layer 13 uses a blue filter to filter blue light, which can prevent blue light from damaging human vision. The privacy layer 14 uses a polarizer, which uses the polarization of light to filter out light at other angles, thereby achieving the function of preventing peeping and spying.

[0029] Furthermore, the adhesive layer 7 is a peroxide-reactive acrylic adhesive. The peroxide-reactive acrylic adhesive needs to be modified and made into a gel-like paste, which is then applied to the privacy layer 14. A transparent plastic film 2 is used to protect it from contact with oxygen in the air. When the film is applied, the transparent plastic film 2 is peeled off to expose it to air. The peroxide-reactive acrylic adhesive reacts with oxygen, thereby acquiring adhesiveness and bonding the film 1 to the surface of the mobile phone screen.

[0030] Furthermore, a hydrophobic coating 15 is deposited on the side of the high-crystal glass layer 12 facing away from the anti-blue light layer 13. The hydrophobic coating 15 is polytetrafluoroethylene deposited by chemical vapor deposition, with a thickness of 5-25 nanometers. The four corners of the hydrophobic coating 15 have clearance blanks corresponding to the anti-crack protective sleeve 9. The function of the hydrophobic coating 15 is to improve surface smoothness, thereby significantly reducing the surface tension between oil and other substances, making it easier to remove oil and achieving a pollution-proof effect. When depositing the hydrophobic coating 15, a clamp can be used to hold the four corners or a mold can be used to cover the four corners. The corner clearance is to prevent the thickness of the four corners of the film 1 from increasing after the anti-crack protective sleeve 9 is applied, which would affect the feel of use.

[0031] Working principle: When using this utility model, the upper plastic frame 3 and the lower plastic frame 4 can be used for quick installation. Place the mobile phone in the mobile phone placement slot 6, align the upper plastic frame 3 and the lower plastic frame 4, and then pull the dark extension section 8 to make the transparent plastic film 2 fall off as a whole. The adhesive layer 7 will be exposed to the air and react with oxygen to have strong adhesion. The adhesive layer 7 makes the film 1 stick to the mobile phone and fit tightly. If there is a corner bump, the anti-crack protective cover 9 will protect the corner of the film 1 and absorb the shock potential energy, which can prevent the film 1 from being damaged by bumps.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
