Description

Technical Field

[0001] This utility model relates to the field of lens protective film technology, and in particular to a lens protective film that utilizes magnetism to facilitate easy replacement. Background Technology

[0002] With the continuous development of the mobile phone industry, mobile phone camera functions are constantly being upgraded, evolving from simple low-pixel shooting to today's precision components with high pixels, multiple lenses, and the ability to achieve complex shooting modes. To protect these important lens components, mobile phone lens protectors have emerged. For example, patent CN202221314102.7 discloses a mobile phone lens protector, including a lens protective layer and a tempered glass layer, designed to facilitate application and reduce the probability of application failure.

[0003] However, existing mobile phone lens protectors present numerous challenges in practical use and replacement. Firstly, many protectors are directly adhered to the lens surface. As exemplified by the product mentioned in patent CN217265528U, this method means that if the protector breaks, fragments easily remain on the back of the lens, requiring significant time to remove during replacement. Furthermore, if air bubbles or misalignment occur during application, residual adhesive greatly complicates the process when reapplying or replacing the protector. Secondly, most existing lens protectors lack convenient disassembly designs. For common tempered glass lens protectors, users must painstakingly pry them off from the edge with their fingernails or other tools, easily scratching the lens or damaging the protector itself. Additionally, while some protective case-style lens protection devices offer some protection, replacing the protector often requires disassembling the entire case, a cumbersome process that may compromise the case's seal and stability, causing considerable inconvenience to users.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figure 1-5 In this embodiment of the present invention, a lens protective film that is easy to replace by using magnetism includes a fixing piece 10 for sticking and fixing around the lens and a magnetic suction piece 20 magnetically adsorbed on the fixing piece 10. An annular protrusion 21 that aligns with the lens is formed on the magnetic suction piece 20, and an annular recess 22 is formed on the annular protrusion 21. A lens film 23 that aligns with the lens is sticked and fixed in the annular recess 22.

[0027] The lens protector consists of a fixing piece 10 and a magnetic clip 20. Before use, the fixing piece 10 is firmly fixed to the area around the phone lens using adhesive, forming a stable mounting base. When the lens protector needs to be installed, the magnetic clip 20 is brought close to the fixing piece 10. Due to the magnetic attraction between the magnetic clip 20 and the fixing piece 10, the magnetic clip 20 automatically and precisely adheres to the fixing piece 10, achieving quick installation. The annular protrusion 21 formed on the magnetic clip 20 matches the contour around the lens, and the lens film 23 adhered within the annular recess 22 can fit tightly against the lens, effectively protecting it. When the lens film 23 needs to be replaced, simply apply appropriate external force to overcome the magnetic attraction, and the magnetic clip 20 can be easily separated from the fixing piece 10, allowing the lens film 23 on the magnetic clip 20 to be replaced. The entire process is simple and quick.

[0028] In the above technical solution, by utilizing magnetic adsorption, the problems of traditional adhesive protective films being difficult to remove and prone to leaving residue are solved. When replacing the magnetic clip 20 or lens film 23, no glue residue will remain around the phone lens, and there is no need to painstakingly remove fragments, greatly reducing the difficulty of replacement and the risk of damage to the lens. In addition, the design of the annular protrusion 21 and the annular concave platform 22 allows the lens film 23 to be precisely aligned with the lens, ensuring that the lens film 23 fits tightly to the lens, improving the protective effect, reducing the possibility of dust, water stains, etc. entering the lens, and also ensuring light transmission and clarity during shooting, thus guaranteeing the quality of mobile phone shooting.

[0029] Please see Figure 2-3 Based on the above technical solution, it is further proposed that multiple first magnetic bodies 11 are embedded on the fixing plate 10, and the first magnetic bodies 11 are flush with the surface of the fixing plate 10. Multiple second magnetic bodies 24 corresponding to the first magnetic bodies 11 are embedded on the magnetic suction plate 20, and the second magnetic bodies 24 are flush with the surface of the magnetic suction plate 20. The fixing plate 10 and the magnetic suction plate 20 are magnetically attracted by the magnetism of the first magnetic bodies 11 and the second magnetic bodies 24, and are positioned by the cooperation of the multiple first magnetic bodies 11 and the multiple second magnetic bodies 24. The first magnetic body 11 and the second magnetic body 24 are respectively embedded on the surface, and their surfaces are flush. On the one hand, this avoids the problem of the magnetic body protruding and affecting the adhesion or causing wear, thus ensuring the flatness and aesthetics of the overall structure. On the other hand, the cooperation of multiple sets of magnetic bodies not only enhances the adsorption force between the fixing plate 10 and the magnetic suction plate 20, making the lens protective film less likely to fall off during use and improving the stability of protection, but also achieves precise positioning by utilizing the corresponding positional relationship of multiple sets of magnetic bodies, allowing the magnetic suction plate 20 to be quickly and accurately adsorbed onto the fixing plate 10, greatly simplifying the installation steps and improving the installation efficiency.

[0030] In the above technical solution, the first magnetic body 11 is made of magnetic material and the second magnetic body 24 is made of magnetic conductive material; or the first magnetic body 11 is made of magnetic conductive material and the second magnetic body 24 is made of magnetic material; by using different combinations of magnetic and magnetic conductive materials, the material cost and magnetic performance are optimized while meeting the magnetic adsorption requirements, so that the product is both economical and practical.

[0031] Please see Figure 3-5 Based on the above technical solution, a positioning frame 25 is further proposed to extend downward from the edge of the magnetic clasp 20. The positioning frame 25 is used to surround the fixing piece 10 so that the magnetic clasp 20 and the fixing piece 10 are positioned by the positioning frame 25. By setting the positioning frame 25 to cooperate with the fixing piece 10, the positioning and installation accuracy of the lens protective film is further optimized. The positioning frame 25 can form a physical limiting structure from the side, which cooperates with the magnetic positioning between the magnetic body to achieve a three-dimensional and precise positioning effect. During the installation process, the user does not need to repeatedly adjust the position of the magnetic clasp 20. He only needs to align the positioning frame 25 with the fixing piece 10 to quickly and accurately install the magnetic clasp 20, which greatly improves the installation efficiency. At the same time, this structure enhances the connection stability between the magnetic clasp 20 and the fixing piece 10, effectively preventing the magnetic clasp 20 from lateral displacement or offset during use, ensuring that the lens film 23 always maintains a precise fit with the lens, and further improving the protection effect on the mobile phone lens.

[0032] Please see Figure 4-5 Based on the above technical solution, in order to adapt to multi-lens mobile phones, it is further proposed that the magnetic clasp 20 is formed with multiple annular protrusions 21, and a lens film 23 is provided on each annular protrusion 21 to protect multiple lenses at the same time. The annular protrusion 21 has an outer annular wall 211 that abuts against the side of the lens and an inner annular wall 212 that surrounds the outer annular wall 211 to abut against the end of the lens. An annular recess 22 is formed on the inner annular wall 212, so that it can firmly abut against the side and end of the lens to form a tight protective boundary. The combination of the annular recess 22 and the inner annular wall 212 allows the lens film 23 to accurately fit the lens surface. An adhesive ring 26 is attached in the annular protrusion 21. The edge of the lens film 23 is adhered to the annular protrusion 21 through the adhesive ring 26, which can ensure the flatness and stability of the lens film 23 and prevent lifting, falling off and other situations.

[0033] Please see Figure 2 Based on the above technical solution, it is further proposed that an adhesive layer 12 be attached to the back of the fixing piece 10. The fixing piece 10 is attached to the lens through the adhesive layer 12, which can ensure that the fixing piece 10 is firmly attached to the lens. The adhesive layer 12 is made of OCA glue or silicone material, which is not easy to leave glue residue, thus ensuring the stable installation of the protective film.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
