Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone peripheral accessories, in particular to a protective film and a magnetic suction mobile phone case. Background Art

[0002] An annular magnet is embedded in the mobile phone case to form a magnetic suction mobile phone case, which helps the magnetic suction fixation of the mobile phone and the charging product. For a hard mobile phone case, it is necessary to first open an annular groove on the inner side of the mobile phone case body, then embed the annular magnet, and then fix it with glue. At this time, the burrs on the edge of the annular groove and the overflow of the glue will cause unevenness, rough appearance and defects near the position where the annular magnet is located, and it is easy to scratch the back of the mobile phone.

[0003] To solve the above problems, some magnetic suction mobile phone cases will choose to cover a layer of opaque sheet material on the surfaces of the annular groove and the magnet. However, this not only increases the material cost, but also causes the thickness of the magnetic suction mobile phone case to increase, which is not conducive to making the magnetic suction mobile phone case thinner and lighter. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a protective film with less production consumables and a thin and light magnetic suction mobile phone case with the protective film.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a protective film, including an outer ring film material and an inner ring film material. The outer ring film material includes a connected outer ring portion and an extension portion. The extension portion is located outside the outer ring portion. The inner ring film material is integrally circular, and the inner ring film material is located in the hollow area of the outer ring portion. An annular isolation area is formed between the inner ring film material and the outer ring portion.

[0006] Further, the extension portion is arranged radially along the outer ring portion.

[0007] Further, a material reduction groove is provided in the central area of the extension portion.

[0008] Further, the material reduction groove is in the shape of a waist-shaped hole.

[0009] Further, the thickness of the outer ring film material is 0.01 - 0.1 mm.

[0010] Further, the thickness of the inner ring film material is 0.01 - 0.1 mm.

[0011] Further, the protective film is made of an opaque material.

[0012] Further, the protective film is a sticker.

[0013] Further, the protective film is a coating formed by solidifying a coating material.

[0014] To solve the above technical problems, the present utility model also adopts the following technical solution: a magnetic suction mobile phone case, including a body and the above-mentioned protective film. An annular groove and a straight groove are provided on the inner side of the body. A ring-shaped first magnet is embedded in the annular groove, and a second magnet is embedded in the straight groove. The protective film is arranged on the inner side of the body. The extension part covers the edge of the second magnet and a part of the area of the body. The outer ring part covers the outer edge of the first magnet and a part of the area of the body. The inner ring film material covers the inner edge of the first magnet and a part of the area of the body.

[0015] The beneficial effect of the present utility model is that this protective film only needs to cover the edge area of the magnet on the magnetic suction mobile phone case, greatly reducing the production consumables, which is beneficial to reducing the manufacturing cost of the magnetic suction mobile phone case with this protective film. At the same time, it can make the overall thickness of the magnetic suction mobile phone case smaller, which is beneficial to enhancing the user experience of consumers. Description of the Drawings
