Referring to fig. 1 to 4 together, a folding screen mobile phone protection case 10 according to an embodiment of the present application will be described. The folding screen protective case for cell phone 10 includes a first case 100, a second case 200, and a side case 300. The first housing 100, the second housing 200, and the side housing 300 may be injection molded parts.

The first housing 100 is adapted to fit over the first portion 21 of the folding screen handset 20. The first housing 100 includes a bottom wall and side walls extending from the periphery of the bottom wall and enclosing with the bottom wall a receiving cavity for receiving the first portion 21 of the folding screen handset 20. The side wall of the first casing 100 is non-closed in the circumferential direction, and extends substantially in a U shape in the circumferential direction, that is, the bottom and the left side of the first casing 100 are opened, respectively, and the opening on the left side forms a first inlet 101 into which the first part 21 is inserted.

Second housing 200 is adapted to fit over second portion 22 of folding screen handset 20. The second housing 200 includes a bottom wall and side walls extending from the periphery of the bottom wall and enclosing with the bottom wall a receiving cavity for receiving the second portion 22 of the folding screen handset 20. The side wall of the second housing 200 is non-closed in the circumferential direction, and extends substantially in a U shape in the circumferential direction, that is, the top and left side of the second housing 200 are opened, respectively, and the opening on the left side forms a second inlet 201 into which the second part 22 is inserted. The side wall of the second casing 200 is provided with a key operation part, a sound transmission hole and a data line plug through hole, and the bottom wall of the second casing 200 is provided with a camera hole for exposing a mobile phone camera.

The side casing 300 has opposite first and second ends 301 and 302. The side case 300 has a substantially U-shaped cross-section and corners of the outer surface may be provided with rounded transitions. The first end 301 of the side casing 300 is rotatably connected to the second casing 200, and the first end 301 can be rotatably connected to the second casing 200 through a rotating shaft mechanism or a rotating shaft. The second end 302 of the side case 300 is detachably abutted against the first case 100, or the second end 302 of the side case 300 is detachably connected with the first case 100. The side housing 300 is rotatable relative to the second housing 200 such that the second end 302 of the side housing 300 is movable relative to the first housing 100 between an open position and a closed position. I.e., the side case 300 can be unfolded and folded, and the second end 302 of the side case 300 is moved to an open position away from the first case 100 when the side case is unfolded. When the side case 300 is folded, the second end 302 thereof moves to a closed position near the first case 100. At this time, the side case 300 can cover the hinge portion 23 of the folding screen handset 20, so that the hinge portion 23 can be effectively protected, and the service life of the folding screen handset 20 can be prolonged.

It is understood that one or more layers of anti-vibration material may be wrapped around the side casing 300, or the hard rubber and the anti-vibration material may be integrally formed into the side casing 300, so as to further enhance the strength of the side casing 300 and enhance the protection performance.

Preferably, the second end 302 of the side housing 300 and the first housing 100 may be connected by magnetic attraction. Thus, when the side casing 300 is closed, the second end 302 of the side casing 300 is attracted to the first casing 100, so as to prevent the side casing 300 from being closed unfirm or opened randomly to affect the protection of the mobile phone. In addition, compared with other connection methods, the magnetic connection method is adopted, so that the step of manually opening the side shell 300 can be omitted in the process of unfolding the folding screen mobile phone 20, and when the first screen and the second screen of the mobile phone are unfolded, the first shell 100 can push against the side shell 300, so that the side shell 300 is prevented from interfering the unfolding of the screen of the mobile phone.

Preferably, in this embodiment, mutually attractive magnetic members are respectively embedded in the second end 302 of the side casing 300 and the corresponding positions of the opposite side walls of the first casing 100. For example, a magnet block 340 may be embedded in one of the end surface of the second end 302 of the side housing 300 and the end surface of the left side of the first housing 100, and a stainless steel block 120 may be embedded in the other, so that the magnetic connection between the side housing 300 and the first housing 100 is realized. Specifically, as shown in fig. 3, two magnet blocks 340 are embedded at intervals on the end surface of the second end 302 of the side housing 300, and two stainless steel blocks 120 are embedded on the end surface of the left side of the first housing 100, so that the magnetic connection between the side housing 300 and the first housing 100 is realized.

It is understood that two magnet blocks may be disposed on the end surface of the second end 302 of the side housing 300 and the end surface of the left side of the first housing 100, respectively, and the two magnet blocks attracted to the side housing 300 and the first housing 100 have opposite polarities, so that the magnetic connection between the side housing 300 and the first housing 100 may also be realized. The first casing 100 and the side casing 300 may not be provided with magnetic members that attract each other, and when the side casing 300 is rotatably connected to the second casing 200 through the rotation shaft mechanism, and the rotation shaft mechanism can provide a driving force for rotating the side casing 300 in a closing direction, so that the side casing 300 can be prevented from being closed firmly or being opened randomly by the driving force provided by the rotation shaft mechanism.

Referring to fig. 2, 3 and 5, the inner wall of the side casing 300 defines a receiving cavity 310 capable of receiving the stylus 30 of the mobile phone. When not in use, the stylus pen 30 can be accommodated in the accommodating cavity 310 of the side shell 300, so that the stylus pen 30 and the folding screen mobile phone 20 are both accommodated in the folding screen mobile phone protective shell 10, the carrying and the use are convenient, and the stylus pen 30 is prevented from being lost; meanwhile, the space occupied by the folding screen mobile phone 20 can be reduced by accommodating the stylus pen 30 in the side housing 300.
