[0030] Reference Figures 1 to 5As an embodiment of the utility model, a mobile phone case for a three-fold flexible screen is provided, comprising a middle shell 1, a first frame shell 2, a second frame shell 3 and a left shell 4. The middle shell 1 is buckled on the middle module of the mobile phone, and comprises a bottom plate 11 and two middle side plates 12. The two middle side plates 12 are respectively fixed on the opposite sides of the bottom plate 11. The other two sides of the bottom plate 11 are vacant and respectively formed with a first connection port 13 and a second connection port 14; the first frame shell 2 is hinged on one side of the first connection port 13, and a first elastic torsion member is provided at the intersection ; The second frame shell 3 is hinged on one side of the second connecting port 14, and a second elastic torsion member is provided at the hinge; the left side shell 4 is buckled on the left module of the mobile phone, including a bottom frame 41 and three side panels 42, the side panels 42 are fixed on the bottom frame 41, and the three side panels 42 are connected and enclosed in sequence to form an opening 43 in the left side shell 4, and when the mobile phone is in the unfolded state, the opening 43 is opposite to the second connecting port 14; when the mobile phone is in the folded state, the first frame shell 2 is buckled on the hinge on the right side of the mobile phone, and the second frame shell 3 is buckled on the left hinge of the mobile phone.
[0031] Since the first frame shell 2 is provided with a first elastic torsion member, and the second frame shell 3 is provided with a second elastic torsion member, when installing this mobile phone case, the mobile phone needs to be in a folded state first, so that it is convenient to install. After the mobile phone is in the folded state, the middle shell 1 is buckled on the middle module of the mobile phone. At this time, the first frame shell 2 is buckled on the hinge on the right side of the mobile phone, and the second frame is buckled on the left hinge of the mobile phone. Then, the left shell 4 is buckled on the left module of the mobile phone, and the installation of the mobile phone case is completed.
[0032] Specifically, the bottom plate 11 is a square structure as a whole, and the two short side edges of the bottom plate 11 are respectively connected to the middle side plate 12. The bottom plate 11 at the first connection port 13 is provided with a first hinge groove 111, and a first hinge shaft 21 is provided on one side of the first frame shell 2. The first hinge shaft 21 is embedded in the first hinge groove 111 and is rotatably connected. The first elastic torsion member is a torsion spring and is sleeved on the first hinge shaft 21. The bottom plate 11 at the second connection port 14 is provided with a second hinge groove 112, and a second hinge shaft 31 is provided on one side of the second frame shell 3. The second hinge shaft 31 is embedded in the second hinge groove 112 and is rotatably connected. The second elastic torsion member is a torsion spring and is sleeved on the second hinge shaft 31. In this embodiment, the bottom plate 11 at the first connection port 13 is provided with at least two first hinge grooves 111, and the position and number of the first hinge shaft 21 are set corresponding to the first hinge grooves 111. The bottom plate 11 at the second connection port 14 is provided with at least two second hinge grooves 112, and the position and number of the second hinge shafts 31 are arranged corresponding to the second hinge grooves 112. The axis centers of the multiple first hinge shafts 21 are located on the same straight line, and the axis centers of the multiple second hinge shafts 31 are located on the same straight line. By setting a torsion spring, the first frame shell 2 can automatically fit the hinge on the right side of the mobile phone after the mobile phone is folded, and the second frame shell 3 can automatically fit the hinge on the left side of the mobile phone, so as to protect the right hinge and the left hinge from scratches.
[0033] Specifically, the bottom frame 41 is a square frame structure as a whole, and the side panels 42 include two side short panels 422 and a side long panel 421.

Then snap the left shell 4 onto the left module of the mobile phone to complete the installation of the mobile phone case.
[0034] Furthermore, the width of the second frame shell 3 is greater than the width of the first frame shell 2, specifically, the width of the second frame shell 3 is equal to twice the width of the first frame shell 2. Since the mobile phone is foldable, the left screen is buckled on top of the right screen, so the width of the second frame shell 3 is equal to twice the width of the first frame shell 2, so the left and right hinges of the mobile phone can be protected.
[0035] Furthermore, both the middle shell 1 and the left shell 4 are provided with reserved holes, which are convenient for the mobile phone to be connected to a charger or earphones, or for the speaker to play sound externally.
[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
