[0002] With the rapid development of science and technology, the tech beauty industry has emerged as a new industry. Fashion IT brands are diversifying with the market's diversification, catering to the increasing number of mobile phone brands and functions. Mobile phone cases are now categorized by material into PC, leather, silicone, fabric, hard plastic, leather cases, metal tempered glass, soft plastic, velvet, and silk. With the advent of smart phones with wireless charging, mobile phone cases have expanded into many more categories.

[0003] Currently, the PC back panels of mobile phone cases used for wireless charging on the market are all made of single-layer PC sheets or three-layer PC sheets. The magnet ring is grooved from the inside, and then the magnet is assembled and a magnetic ring cover is attached. The magnet ring can be clearly touched. This structure can easily cause the magnet to fall off, resulting in poor stability, uneven appearance, gaps around the magnetic ring, and an overall unsightly appearance. At the same time, the magnet will shift during the drop test, resulting in a short service life and high defect rate. To address this problem, the inventors designed a mobile phone case with a sandwich PC sheet. Utility Model Content
