[0002] With the development of technology and the widespread use of electronic devices, screen protectors or cases have become important accessories. They not only provide protection against drops and scratches but also serve as personalized decorative items. However, traditional phone cases typically only offer basic protection. Most phone cases on the market have a fixed appearance and relatively limited functionality. If users want to change their style, they need to buy and replace the entire phone case, which is costly and environmentally unfriendly. Some products have attempted to use replaceable back panels or insertable cards, but these have the following drawbacks:

[0003] 1. Complex structure: It usually requires mechanical connection structures such as clips and screws, which are inconvenient to disassemble and easy to damage.

[0004] 2. Limited patterns: The number of insertable card or back panel patterns is limited, and the degree of user customization is low.

[0005] 3. Loose fit: Mechanical connection may cause the back panel to not fit tightly with the shell, resulting in warping, dust ingress, or affecting the feel.

[0006] 4. High cost: The cost of materials for making back panel molds with precision buckles or magnetic attraction is relatively high.

[0007] 5. Not reusable: Traditional stickers and films are for single use only and cannot be reused, which is not environmentally friendly.

[0008] Therefore, there is an urgent need for a protective film that is simple in structure, low in cost, easy to replace, and can highly meet the personalized needs of users. Utility Model Content

[0038] Example 1

[0039] like Figures 1 to 4 As shown, a replaceable electrostatic adsorption film for electronic devices according to the first aspect embodiment of the present invention includes a film body 1, which is sheet-shaped and has a first lens window 2.

[0040] The film body 1 includes a substrate layer 4, an electrostatic adsorption layer 5, and a printing layer 6. The substrate layer 4 is disposed between the electrostatic adsorption layer 5 and the printing layer 6. The substrate layer 4 serves as a support and is usually a high-transparency, high-flexibility PET (polyethylene terephthalate) film, or a composite of PET film and materials such as PC and acrylic. In addition to transparent materials, mirrored or iridescent composite PET films can also be used. The electrostatic adsorption layer 5 is a layer of special silicone or polyurethane material coated or laminated on the back of the substrate layer. This layer does not contain any physical adhesive. By making close contact with the surface of the original back glass of the phone or the phone case below the window on the back panel, electrostatic force is generated, thereby achieving reversible and residue-free adsorption and fixation. The printing layer 6 uses UV printing, lamination, and other processes to print any pattern, text, or photo required by the user.

[0041] In this embodiment, it should be noted that the electronic device is a mobile electronic terminal device, such as a mobile phone or tablet computer. This application uses a mobile phone as an example for explanation. The screen protector body 1 can be directly attached to the back panel of the mobile phone 7. Figures 1 to 4 As shown; it can also be used with a phone case, such as Figures 5 to 10 As shown;

[0042] A protective layer is provided outside the printed layer 6. The protective layer is transparent and can be made of epoxy resin, UV resin, etc., which can provide good protection for the printed layer 6, making it less prone to scratches and extending its service life.

[0043] The technical effects achieved in this embodiment are as follows: the screen protector body 1 can be directly adhered to the mobile phone 7 or the mobile phone case through electrostatic adsorption. Utilizing electrostatic adsorption, the screen protector body 1 perfectly adheres to the back panel of the mobile phone or the mobile phone case without bubbles or gaps; there is no damage to the mobile phone or the mobile phone case when it is removed, and there are no residual adhesive residues. It can be reused countless times; the screen protector body 1 has a printing layer 6, which can easily be customized with any pattern to meet the personalized needs of users; the structure is simple, the cost is low, and it is easy to replace. During use, users do not need to replace the entire mobile phone case, but only need to purchase low-cost screen protectors with different patterns.
