[0002] The price of existing foldable screen mobile phones is relatively high. Therefore, in order to avoid damage caused by slight bumps during use, most people will wear corresponding mobile phone cases during daily use. The mobile phone cases of existing foldable screen mobile phones mainly include two shells for being mounted on both sides of the mobile phone. The main protected part is also the frame part of the foldable screen mobile phone. At the same time, in order to ensure the smooth rotation of the foldable screen mobile phone case, the hinge part of the foldable screen mobile phone is not protected. However, due to the use of mechanical hinges, the foldable screen mobile phone itself is relatively weak in terms of drop and pressure resistance. In addition, if the foldable screen mobile phone adopts the inward folding method, after folding, the hinge part is directly exposed to the outside, which is more susceptible to damage from accidental situations such as impact.
[0003] Therefore, when wearing a mobile phone case, it is also necessary to have a certain protective effect on the hinge part of the folding screen mobile phone, and it is also necessary to ensure that the mobile phone case can adapt to the folding screen mobile phone for folding, but the existing folding screen mobile phone cases cannot meet the above requirements.

The protection plate 30 is rotatably connected to the rear case 20, and a torsion spring 31 is provided between the protection plate 30 and the rear case 20. One end of the torsion spring 31 is fixedly connected to the protection plate 30, and the other end is fixedly connected to the rear case 20. The torsion spring 31 enables the protection plate 30 to maintain a rotational force toward one side of the rear case 20.
[0023] When in use, the front shell 10 and the back shell 20 are first fixed to the two sides of the folding screen mobile phone respectively, and the protective plate 30 is correspondingly covered on the hinge part of the folding screen mobile phone, and under the action of the torsion spring 31, the protective plate 30 rotates toward the side of the back shell 20, so that the protective plate 30 and the hinge part are kept in contact, and when the folding screen mobile phone is folded or unfolded, the hinge part rotates together, and the protective plate 30 can also rotate around the back shell 20, so that no matter whether the folding screen mobile phone is in the unfolded state or the folded state, the protective plate 30 actually corresponds to the hinge part, and the protective plate 30 is used to play a protective role, while ensuring the smooth rotation of the folding screen mobile phone.
[0024] A storage groove 21 is provided on one side of the rear shell 20 close to the protective plate 30, and a rotating shaft 22 is provided in the storage groove 21. The rotating shaft 22 is rotatably connected to the rear shell 20, and a lug 32 is provided on the protective plate 30 corresponding to the storage groove 21. The lug 32 is fixedly connected to the rotating shaft 22, and a torsion spring 31 is sleeved on the surface of the rotating shaft 22. The lug 32 can be used to maintain a rotational connection between the protective plate 30 and the rear shell 20, and the rotating shaft 22 is also provided in the rear shell 20 to protect the rotating shaft 22. At the same time, the storage groove 21 is used to avoid the lug 32 from rotating in the storage groove 21, thereby avoiding the situation where the rotation of the lug 32 is restricted, and the appearance is smoother and simpler.
[0025] In the above scheme, a slot 23 is provided at one end of the storage slot 21, one end of the rotating shaft 22 is inserted into the slot 23, a cover plate 24 is fixedly provided above the slot 23, and one end of the rotating shaft 22 is restricted in the slot 23 by the cover plate 24. The cover plate 24 is used to facilitate people to assemble the rotating shaft 22, and the cover plate 24 can be used to fix the rotating shaft 22, while one end of the rotating shaft 22 can also rotate in the slot 23.
[0026] Please refer to Figure 4 , equivalent to the above scheme, another installation method of the rotating shaft 22 is: the storage slot 21 is provided with a rotating cavity 211 at both ends of the rotating shaft 22, and the two ends of the rotating shaft 22 are inserted into the rotating cavity 211 for rotational connection, so that the rotating shaft 22 can be better restricted in the storage slot 21, the possibility of loosening can be reduced, and the use of other components can be reduced.
[0027] There are two storage slots 21, which are opened on the upper and lower sides of the rear shell 20, and the lugs 32 are arranged corresponding to the storage slots 21, so as to increase the stability of the protection plate 30 when rotating, and the protection plate 30 is concave on the side close to the rear shell 20, so that the protection plate 30 can better fit with the hinge part, so that the protection plate 30 is wrapped around the outside of the hinge part to play a better protective role.
[0028] Please refer to Figure 5 and Figure 6 The rotating shaft can be a component of an ear rod, wherein the rotating shaft 22 includes a sleeve 221, and ejector pins 222 are provided at both ends of the sleeve 221. The ejector pin 222 is slidably connected to the sleeve 221. A spring 223 is provided in the sleeve 221, and both ends of the spring 223 are respectively in contact with the ejector pin 222, so that both ends of the rotating shaft 22 can be retracted and retracted, and the spring 223 can be used to maintain the ejection state, which is convenient for people to install and fix the rotating shaft 22, and directly snap it into the storage groove 21, so that there is no need for a cover plate 24 for fixing, the assembly process is small, the accessories are few, it is simple and convenient, and the stability of the main body is ensured.
[0029] The rear shell 20 is provided with a circular hole corresponding to the torsion spring 31, and the protective plate 30 is provided with a slot corresponding to the torsion spring 31. One end of the torsion spring 31 is embedded in the circular hole, and the other end is embedded in the slot. During the production process, injection molding can be used to integrally form one end of the torsion spring 31 with the rear shell 20, and the other end of the torsion spring 31 can be inserted into the slot during installation, thereby making the connection more secure and the installation more convenient.
