Description

Technical Field

[0001] The utility model relates to the technical field of electronic device accessories, and particularly relates to a protective case for an electronic device. Background Art

[0002] To meet people's pursuit of large mobile phone screens, folding mobile phones have emerged on the market later, such as two-fold mobile phones and three-fold mobile phones. Among them, the three-fold mobile phone is composed of a first folding screen, a second folding screen, and a third folding screen, and has the advantages of a large screen after unfolding and a very small volume after folding, which can be put into a pocket and is very convenient to carry.

[0003] Due to the relatively special folding structure of the three-fold mobile phone, that is, the screens of the left and right parts will fold towards the middle part. At this time, a structure will appear in which the screen of the left part or the right part is sandwiched between the screens of the other two parts. If the traditional protective case structure is used, the protective case will fold along with the screen, and at this time, the protective case will also be sandwiched between the two parts of the screen. For a folding screen mobile phone, the folding structure is set. If there is other thing sandwiched between the two parts of the screen, it will cause the folding structure to not fold in place, that is, the folding screen mobile phone cannot be folded normally, or the mobile phone will be damaged when folding.

Among them, in a specific implementation of the embodiment of the present utility model, the first connecting member is a first flexible member 4, and the second connecting member is a second flexible member 5. The first shell 1 is connected to the second shell 2 through the first flexible member 4, and the third shell 3 is connected to the second shell 2 through the second flexible member 5. When the electronic device is in a folded state, the first flexible member 4 wraps the connection between the first folding screen 7 and the second folding screen 6, and the second flexible member 5 wraps the connection between the third folding screen 8 and the second folding screen 6. Specifically, the other end of the first flexible member 5 is connected to the first notch 205, one end of the second flexible member 4 is connected to the second notch 204, and the other end of the second flexible member 4 is connected to the first back plate.
