Description

Technical Field

[0001] The utility model relates to the technical field of protective shells, and in particular to a mobile phone protective shell with a screen. Background Art

[0002] Mobile phone cases are decorations that protect or decorate the appearance of mobile phones. With the rapid development of science and technology, the technology beauty industry has emerged as a new industry. It has become diversified in response to the increase in mobile phone brands and functions. Mobile phone protective cases are divided into PC cases, leather, silicone, cloth, hard plastic, leather cases, metal tempered glass cases, soft plastic, velvet, silk, etc. According to the texture, however, the patterns formed on the outer surfaces of these mobile phone cases cannot be changed, so that a mobile phone case can only maintain one appearance, which causes users to frequently change mobile phone cases due to fashion needs.

[0003] In order to realize the variable pattern, the utility model patent with publication number "CN216122547U" and the name "a mobile phone case with a display screen with good heat dissipation" discloses a mobile phone case with a display screen with good heat dissipation, including a mobile phone shell, a display screen panel is installed on the back of the mobile phone shell, and both sides of the mobile phone shell are provided with air holes connected to the inner interlayer of the mobile phone shell above the display screen panel, a group of heat dissipation mechanisms connected to the interlayer of the mobile phone shell are installed at the bottom of the back of the mobile phone shell, and a charging opening is opened in the middle of the bottom of the mobile phone shell, a connecting wire is connected to the bottom of the mobile phone shell, and the other end of the connecting wire is connected to the C port connected to the charging opening, and the heat dissipation mechanism includes a windshield shell, a fan, a guide shell, and a guide groove. When in use, the C port is inserted into the charging socket of the mobile phone, and the mobile phone supplies power to the display screen panel and the fan through the connecting wire. Although it can display different patterns through the display screen, it needs to occupy the charging socket of the mobile phone, and also needs a fan for heat dissipation, which not only consumes a lot of energy, but also occupies a lot of space, making the mobile phone shell thicker and bulky.
