Referring to FIG. 4 and FIG. 5, in the embodiment, the scroll member 30 includes a sliding seat 31 and a rotating shaft 33. Both ends of the rotating shaft 33 are rotatably connected to the sliding seat 31, and the flexible screen is wound around the same. The shaft 33 is described. Thus, the rotating shaft 33 is rotated relative to the sliding seat 31 such that the flexible screen is wound on the side of the rotating shaft 33.

In the present invention, the rotational connection of the rotating shaft 33 and the sliding seat 31 can be performed in the following three ways:

The first type of the rotating shaft 33 is provided with a mounting hole 331. The sliding seat 31 is provided with two rotating engaging members 311, and a rotating engaging member 311 is received in a mounting hole 331, and the rotating fitting member An outer wall surface of the 311 abuts against a hole wall of the mounting hole 331, and the rotating shaft 33 rotates around the rotary fitting 311.

The mounting hole 331 is a blind hole having a side hole wall and a bottom hole wall. The rotary fitting 311 abuts against the side hole wall of the mounting hole 331 and rotates with the center line of the rotary fitting 311 as an axis. The outer wall surface of the rotary fitting 311 is a curved surface, and the curved surface may be a circular arc surface. Thus, the curved surface of the rotary fitting 311 is rotatably slidably engaged with the side hole wall of the mounting hole 331 to reduce the concentricity deviation and assembly deviation of the mounting holes 331 on both sides of the sliding seat 31.

The second type of the rotating shaft 33 is provided with a rotating protrusion 333. Both ends of the sliding base 31 are provided with a bearing 313. A rotating protrusion is inserted into a bearing 313 and rotates in the bearing 313.

By the cooperation of the rotating projection 333 and the bearing 313, the frictional force of the rotation of the rotating shaft 33 is reduced, so that the rotation of the rotating shaft 33 is more stable.

The third type: one of the two ends of the rotating shaft 33 is provided with a mounting hole 331, and the other one is provided with a rotating protrusion 333. One end of the sliding seat 31 is provided with a rotating fitting 311, and the other end is provided with a bearing 313. The rotating fitting 311 is received in the mounting hole 331 , and the outer wall surface of the rotating fitting 311 abuts against the hole wall of the mounting hole 331 . The rotating protrusion 333 is inserted into the bearing 313 and rotates in the bearing 313 .

That is, the bearing 313 and the rotary fitting 311 are respectively disposed at both ends of the rotating shaft 33, and the mounting is performed in such a manner that the advantages of the two mounting modes can be integrated, and the concentricity deviation and assembly of the mounting holes 331 on both sides of the sliding seat 31 can be reduced. The deviation can further reduce the frictional force of the rotation of the rotating shaft 33, so that the rotation of the rotating shaft 33 is more stable.

Further, when the sliding seat 31 is provided with the rotating fitting 311, the end of the rotating fitting 311 is provided with a second torsion spring 315, and the end of the second torsion spring 315 facing away from the rotating fitting 311 is The hole walls of the mounting holes 331 are connected. When the flexible screen is gathered, the flexible screen is completely wound around the outer side of the rotating shaft 33, and the second torsion spring 315 is in an elastically compressed state. The second spring is in an elastic recovery state when the flexible screen is opened. The second torsion spring 315 provides power for opening the flexible screen for the rotation of the rotating shaft 33 while making the rotation of the rotating shaft 33 more stable. The second torsion spring 315 is a tower-type torsion spring. When the tower-type torsion spring is deformed, the tower bottom of the tower-type torsion spring is connected with the rotary fitting 311, and the tower tip of the tower-type torsion spring and the bottom wall of the mounting hole 331 are connection. In the deformation, the tip of the tower is deformed first. Here, since the number of turns of the torsion spring is small, it is easy to be deformed, and during the rotation of the rotating shaft 33, the deformation of the second torsion spring 315 is more and more deformed. However, due to the arrangement of the tower type torsion spring, the number of turns around the torsion spring at the bottom of the tower at the upper end is relatively large, so that a certain resistance is generated here, so that the rotation of the rotating shaft 33 is relatively stable, and the rotation of the rotating shaft 33 does not occur suddenly. The acceleration causes the rotation of the shaft 33 to be smoother.

The present invention also provides a mobile terminal, which may be a mobile phone or a tablet computer. The mobile terminal includes a flexible screen opening and closing structure 100. The specific structure of the opening and closing structure 100 of the flexible screen refers to the above embodiment, because the mobile terminal The terminal adopts all the technical solutions of all the foregoing embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the foregoing embodiments, and details are not described herein again.
