Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment accessories, in particular to a protective shell with a film sticking function and a film sticking method. Background Art

[0002] Nowadays, electronic devices such as mobile phones and tablets have become one of the important communication tools in people's lives. In order to protect these commonly used electronic devices, many protective accessories for protecting these electronic devices have emerged, such as protective cases, protective films, etc. When sticking protective films on the screens of electronic devices, it is necessary to use film sticking tools to accurately and quickly stick the protective films on the screens of electronic devices. Existing film sticking tools often only have the function of sticking films, and sticking films is not a very frequent operation for users. Therefore, film sticking tools are often disposable tools. After the film sticking is completed, the film sticking tools are often discarded by users, resulting in a waste of resources. Based on this situation, a Some manufacturers are considering combining the protective case and the film-applying tool into one. In order to avoid waste, for example, a Chinese patent with application number (2019219336686) discloses "a mobile phone protective case-type film-applying tool", comprising: a mobile phone case adapted to the mobile phone to be film-applied, the mobile phone case being arranged horizontally; at least two positioning blocks, the positioning blocks being arranged on the top corners of the mobile phone case, the positioning blocks being detachably connected to the top of the outer wall of the mobile phone case, after the mobile phone to be film-applied is placed in the mobile phone case, the positioning blocks are located vertically above the front of the mobile phone to be film-applied, and the positioning blocks are provided with a right-angle notch for positioning the mobile phone protective film to adapt to the screen of the mobile phone to be film-applied.

[0003] This solution combines the film sticking tool with the protective case. In order to realize the function of positioning the protective film, it is also necessary to set a detachable positioning block at the top of the outer wall of the mobile phone case. During use, the positioning block will inevitably be offset or deformed, affecting the positioning of the protective film and thus affecting the film sticking effect. Therefore, setting such a structure on the protective case cannot guarantee the film sticking effect well. How to make the protective case better realize the film sticking function when the film sticking tool and the protective case are combined into one is a problem worthy of careful consideration. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a protective case with a film sticking function and a film sticking method.

[0005] The technical solution of the present invention is achieved in this way:
