[0021] A mobile phone back shell 100 with a protective film, a protective film 10, a first magnetic ink layer 20, a second magnetic ink layer 30, a cover bottom ink layer 40, a glass layer 50, a camera hole 60, a fingerprint touch area 70. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] The present application provides a mobile phone back shell 100 with a protective film. Please refer to Figure 1, including: a protective film 10, a first magnetic ink layer 20, a second magnetic ink layer 30, a bottom cover ink layer 40, and a glass layer 50. The protective film 10, the first magnetic ink layer 20, the second magnetic ink layer 30, the bottom cover ink layer 40, and the glass layer 50 are stacked in sequence. Among them, the color of the bottom cover ink layer 40 is black, and the black bottom cover ink layer 40 can cover the internal structure of the mobile phone, making the mobile phone more beautiful and grand. The protective film 10 is arranged on the outermost side of the mobile phone back shell. The protective film 10 is used to protect the first magnetic ink layer 20, the second magnetic ink layer 30, the bottom cover ink layer 40, and the glass layer 50. On the one hand, it prevents the glass layer 50 from being scratched, knocked, or broken, playing a role in protecting the mobile phone back shell. Thus, users can feel the beauty of the mobile phone and improve the user experience. On the other hand, it can reduce the weight brought by the protective case, eliminating the need for users to put on an anti-drop and anti-knock protective case on the mobile phone shell.

[0024] It should be noted that, please refer to Figure 2 , through holes 60 for installing a camera are respectively formed on the protective film 10, the first magnetic ink layer 20, the second magnetic ink layer 30, the bottom cover ink layer 40, and the glass layer 50, and the through holes 60 communicate with each other. Moreover, a fingerprint touch area 70 can be arranged on the glass layer 50. The fingerprint touch area 70 is electrically connected to the ITO touch layer in the glass layer 50, and the ITO touch layer is electrically connected to the mobile phone main board. Users can touch and unlock the mobile phone on the protective film 10.

[0025] In an embodiment, the first magnetic ink layer 20 and the second magnetic ink layer 30 are magnetically attracted to each other. The first magnetic ink layer 20 and the second magnetic ink layer 30 have opposite polarities attracting each other. The protective film 10 and the first magnetic ink layer 20 can be detached simultaneously, enabling the scratched or damaged protective film 10 to be replaced at any time. Moreover, replacing a part of the mobile phone back shell can reduce the replacement cost, with high replacement efficiency, allowing users to have a brand-new mobile phone back shell with a better appearance. Furthermore, the first magnetic ink layer 20 and the second magnetic ink layer 30 are doped with magnetite particles or hematite particles to enhance the magnetism between the first magnetic ink layer 20 and the second magnetic ink layer 30, making the magnetic attraction between the two more firm, and preventing them from being displaced during a collision and losing the protection of the protective film 10 for the mobile phone back shell.

[0026] Furthermore, the particle diameters of the magnetite particles and the hematite particles are needle-shaped crystals with a diameter less than 1um.

[0027] Still further, the thickness of the second magnetic ink layer 30 is 25um - 35um.

[0028] In one embodiment, the outer side of the protective film 10 has a matte layer, which increases the maximum static friction between the mobile phone and the user's hands, achieving the anti-slip function. Moreover, stripe patterns or textures are provided on the matte layer, making the back shell of the mobile phone more aesthetically pleasing. In addition, the surface of the protective film 10 is hardened and has a good protective effect. The color on the protective film 10 can be set according to the user's preference, further enhancing the aesthetic feeling, such as single colors like black, white, pink, light blue, etc.; gradient colors like gradient blue and gradient red; or combinations of multiple colors.

[0029] Furthermore, the thickness of the bottom cover ink layer 40 is 20um. The thickness of the bottom cover ink layer 40 is thick enough and the color is deep enough to completely cover the internal structure of the mobile phone. Preferably, the material of the glass layer 50 is Corning GG5 / GG6.

[0030] In addition, the protective film 10 is a PET film, and the PET film can withstand the high temperature generated by the operation of the mobile phone, improving the high-temperature resistance of the back shell of the mobile phone.

[0031] The above-described embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
