[0025] 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.

[0026] In one typical embodiment of this application, please refer to Figures 1-3 As shown, a square magnetic filter phone case includes: a phone case body 1 with a phone case filter magnetic groove 2, and a magnetic filter assembly. The magnetic filter assembly magnetically engages with the phone case filter magnetic groove 2. The magnetic filter assembly includes a square retaining ring 8, a filter retaining ring magnetic 9, a square filter 10, and a positioning slot 11. The square filter 10 is disposed inside the square retaining ring 8, the filter retaining ring magnetic 9 is disposed on the square retaining ring 8, and the positioning slot 11 is opened on one side of the square retaining ring 8.

[0027] The phone case body 1 includes a ring and mute switch 3, a volume up button 4, a volume down button 5, and a lock screen button 6. A wireless charging magnetic charging device 7 is located on the back of the phone case body 1. The square filter 10 is made of optical-grade glass with an anti-reflective coating, effectively improving light transmittance and color reproduction while reducing the impact of reflected light on photography. The phone case body 1 is made of polycarbonate, and the area where it contacts the square retaining ring 8 has a cushioning structure to provide extra protection for the filter and reduce the impact on the phone. The magnetic force of the magnetic filter assembly is adapted to the daily shaking and collision conditions of the phone, ensuring a stable connection between the filter assembly and the phone case body 1. The size of the phone case filter magnetic slot 2 is compatible with the square retaining ring 8. When the two are in use, the square retaining ring 8 can be tightly embedded in the phone case filter magnetic slot 2, achieving quick and accurate installation and positioning.

[0028] During the manufacturing process, the main frame 1 of the phone case made of PC material and the buffer frame made of TPU material are first manufactured using injection molding. When manufacturing the PC frame, a high-precision mold is used to precisely form the magnetic filter groove 2 for the camera area, with pre-reserved positions for magnet embedding within the groove. High-performance neodymium iron boron magnets, after rigorous selection, are embedded into the pre-reserved positions in the mounting groove according to the design layout, and fixed with high-strength, high-temperature resistant adhesive that does not affect the magnetic force, ensuring that the magnets will not loosen or fall off during long-term use. Then, the TPU frame and PC frame are injection molded a second time, tightly bonding them into a single unit to complete the phone case manufacturing. After manufacturing, the phone case undergoes comprehensive quality inspection, including dimensional accuracy testing, magnet strength testing, and PC-TPU bonding strength testing, to ensure that the phone case quality meets design requirements.

[0029] The production of square filters utilizes high-purity, low-dispersion optical glass blanks, which are cut to design dimensions to obtain square filter blanks (10). These blanks undergo multiple precision processes, including grinding and polishing, to ensure surface flatness meets optical-grade standards, guaranteeing uniform light transmission and image clarity. Depending on the functional requirements of different filters, advanced vacuum coating technology is used to deposit corresponding thin films onto the filter surface. For example, ND filters are coated with a metal film with uniform light absorption characteristics, and CPL filters are coated with a special polarizing film to achieve their respective optical functions. After coating, matching filter retaining rings (magnetic clips) (9) are embedded into the filter edges and securely fixed with high-quality adhesive, ensuring the magnet strip and filter become a unified whole. Finally, the manufactured filters undergo optical performance testing, including tests for transmittance, color reproduction, and polarization, to ensure the optical quality meets professional photography standards.

[0030] In the product assembly and testing phase, the manufactured square filter 10 is assembled and tested with the main body of the phone case 1. The strength of the magnetic connection is checked, and the filter is tested for detachment and the protective performance of the phone case by simulating pulling, shaking, and dropping actions common in daily use. A photo test is then conducted on the phone with the filter installed to check image quality and observe for issues such as vignetting, uneven lighting, and color deviation, ensuring the filter is not misaligned and functions properly. Simultaneously, the button feel and interface compatibility of the phone case are tested to ensure the product meets design requirements in all aspects. After comprehensive testing and passing all indicators, the product is packaged and shipped to the market for user use.

[0031] Working principle:

[0032] In use, the user first selects the appropriate square magnetic filter assembly according to their shooting needs. Align the positioning slot 11 on one side of the square retaining ring 8 with the magnetic filter slot 2 on the phone case body 1, and use magnetic attraction to attach the magnetic filter assembly to the phone case. The filter retaining ring magnet 9 and the magnet inside the phone case filter magnetic slot 2 attract each other and fit tightly, thus achieving quick filter fixation. When it is necessary to change the filter, the user simply needs to gently pull up the square retaining ring 8 through the positioning slot 11 to remove the magnetic filter assembly from the phone case, and then install other types of filters following the same steps.

[0033] The square filter 10 is made of optical-grade glass and coated with an anti-reflective film, which can effectively improve the transmittance and color reproduction of light during shooting, reduce the impact of reflected light on the shooting effect, and improve the shooting quality. The wireless charging magnetic device 7 on the back of the phone case body 1 can magnetically attach with a wireless charging device without affecting the phone's wireless charging function. At the same time, the ring and mute switch 3, volume up button 4, volume down button 5, and lock screen button 6 on the phone case all work normally and do not affect the normal use of the phone.

[0034] Throughout the process, the magnetic filter assembly is magnetically connected to the main body of the phone case 1, making installation and removal simple and convenient without the need for other tools. This allows users to quickly change filters in different shooting scenarios, improving shooting efficiency. The square filter design perfectly matches the phone's square lens module, providing more comprehensive lens coverage, effectively reducing vignetting and light loss, improving image quality, and ensuring ideal shooting results in various shooting environments.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
