The first notch 201 and the second notch 202 are respectively connected to the two sides of the second embedding cavity 203.

[0049] The first housing 10 and the second housing 20 are connected by a first folding structure protection member 41 and are foldably arranged with each other. The second folding structure protection member 42 is connected to the second housing 20 and is located at two opposite ends of the second housing 20 with respect to the first folding structure protection member 41. The first folding structure protection member 41 is connected to the first notch 201, and the second folding structure protection member 42 is connected to the second notch 202.

[0050] And, the protective shell structure also includes a rotating shaft, and the first folding structure protection member 41 is rotatably connected to the first shell 10 and / or the second shell 20 through the rotating shaft; and / or the second folding structure protection member 42 is rotatably connected to the second shell 20 through the rotating shaft. Specifically, in this embodiment, the rotating shaft includes a first rotating shaft 61, a second rotating shaft 62 and a third rotating shaft 63, the first rotating shaft 61 is rotatably disposed in the opening groove 102, and the second rotating shaft 62 and the third rotating shaft 63 are rotatably disposed in the first notch 201 and the second notch 202 respectively. The first folding structure protection member 41 is connected between the first rotating shaft 61 and the second rotating shaft 62, and the second folding structure protection member 42 is connected to the third rotating shaft 63.

[0051] It should be noted that: the first folding structure protection member 41 may include a first deformable structure, and the first shell 10 and the second shell 20 may be folded directly through the first deformable structure, without using a rotating shaft structure; and / or, the second folding structure protection member 42 may include a second deformable structure, and the second folding structure protection member 42 may be rotated relative to the second shell 20 directly through the second deformable structure, and also without using a rotating shaft structure. The first deformable structure and the second deformable structure are both made of soft materials, such as soft leather, cloth or plastic, etc., without limitation.

[0052] The method of using this embodiment is described in detail as follows:

[0053] When in use, the electronic device 50 is unfolded, and then the first body 51 and the second body 52 of the electronic device 50 are respectively embedded and fixed in the first embedding cavity 101 and the second embedding cavity 203 from top to bottom. When folding, first, the first body 51 is flipped and folded inwardly relative to the second body 52, so that the first body 51 is superimposed on the second body 52. ​​At this time, the first shell 10 is superimposed on the second shell 20, and at the same time, the first folding structure protection member 41 wraps and covers the outer side of the first rotating shaft hinge 54 of the electronic device 50 to protect the first rotating shaft hinge 54 of the electronic device 50; then, the third body 53 is flipped and folded inwardly relative to the second body 52, so that the third body 53 is superimposed on the first body 51, and at the same time, the second folding structure protection member 42 wraps and covers the outer side of the second rotating shaft hinge 55 of the electronic device 50 to protect the second rotating shaft hinge 55 of the electronic device 50.

The receiving cavity 301 is used to accommodate the third body 53 of the electronic device 50 to protect the third body 53. When only one side of the electronic device 50 is a screen, the side and back of the electronic device 50 can be well protected.

[0061] The method of use of this embodiment is the same as that of the aforementioned second preferred embodiment, and the method of use of this embodiment will not be described in detail here.

[0062] The design focus of the utility model is that by further adding a second folding structure protection member and a third shell, effective and comprehensive protection can be provided for each main body and each hinge part of the three-fold electronic device, and the structure can better adapt to the three-fold electronic device, bringing convenience to use.
