The structure of the second body 12 is consistent with that of the first body 11 . For the description of the structure of the second body 12 , please refer to the above description about the first body 11 , which will not be repeated here.

The metal sheet 131 is stacked on the upper surfaces of the first body 11 and the second body 12 , and two ends of the metal sheet 131 are fixedly connected to the first body 11 and the second body 12 respectively. In this embodiment, the metal sheet 131 is a square sheet structure, and in order to ensure sufficient connection strength, the metal sheet 131 is a steel sheet. Both ends of the metal sheet 131 can be respectively fixed on the first body 11 and the second body 12 by screws, so as to connect the first body 11 and the second body 12 together. In addition, the way of screw connection can also facilitate disassembly and maintenance. Since the mobile terminal 100 with a flexible screen needs to be stacked without wrinkles when it is bent, the thickness of the metal sheet 131 is preferably 0.1 mm. It can be understood that, in other embodiments, the metal sheet 131 may also be a relatively soft aluminum sheet or iron sheet or the like.

In addition, in order to further ensure the bending performance of the metal sheet 131, a plurality of through holes (not shown) arranged side by side are also opened on the metal sheet 131, and the plurality of through holes can be round holes, square holes Or U-shaped hole, etc. Meanwhile, in order to ensure the structural strength of the metal sheet 131 , the center-to-center distance between two adjacent through holes is greater than the diameter of the through holes.
