[0020] The positions of the rotation axis of the right rotation connecting structure and the right support frame 32 are such that when the flexible screen terminal is being folded from an unfolded state, the left connecting member 52 (with the left casing 200) moves in a direction away from the intermediate support structure, and when the flexible screen terminal is being unfolded from a folded state, the right connecting member 52 (with the right casing 200) moves in a direction towards the intermediate support structure.

[0021] The rotation axes B1 and B2 along which the left and right swivel connecting structures and the intermediate support structure are rotatably connected are both higher than the flexible screen support surface 10 of the intermediate support structure and are located close to or above the height of the intermediate layer of the flexible screen.

The intermediate rotating block 302 is rotatably connected to the intermediate support structure via an arc-shaped guide rail and an arc-shaped block, and realizes interlocking connection between the front and rear on the rotation stroke of the two-stage concentric rotating connecting structure via a limit structure. Right rotating connecting fineThe rotating connecting arm 42 is rotatably connected to its intermediate rotating block 303 via an arc-shaped guide rail and an arc-shaped block. The intermediate rotating block 303 is rotatably connected to the intermediate support structure via an arc-shaped guide rail and an arc-shaped block, and realizes interlocking connection between the front and rear of the two-stage concentric rotating connecting structure on the rotation stroke via a limit structure.

This spring support structure can use a compression spring 73. The pressing direction of the pressing structure is either radial or a pressing direction that provides rotational opening torque to the left rotating connection structure or the right rotating connection structure. By controlling the pressing contact angle, the pressing direction is diagonally upward and outward when the folded-back flexible screen terminal is opened flat. See FIG. 10.

The left and right connecting members 51 and 52 are also placed below the left and right movable support plates 61 and 62, respectively.

[0028] The synchronous counter-rotation coupling mechanism may use a gear coupling structure including a gear coupling frame 2. The gear coupling frame 2 is provided at the end of the intermediate support structure. The synchronous counter-rotation coupling mechanism includes four gears 21, 22, 23, and 24 that are sequentially meshed and coupled. The gear shafts of the gears 21 and 24 are connected to the left support frame 31 and the right support frame 32, respectively.

[0031] The motion mechanism further includes a structure that increases resistance when the flexible screen terminal is opened or folded. This structure serves to provide a rotation stop, a positioning function, or simply a tactile feedback for operation. As shown in FIG. 8, this structure can be achieved by using a synchronous counter-rotation coupling mechanism. Holes into which the gear shafts of the gears 21 and 24 corresponding to the gear coupling frame 2 are inserted are provided in the spring tube structure. The spring tube structure clamps the gear shafts of the gears 21 and 24 to provide resistance.

[0032] The resistance-increasing structure can also be provided in the sliding guide structure. This structure includes a spring tube. The spring tube is connected to the sides of the left connecting member 51 and the right connecting member 52, respectively. The guide sleeves 54 are provided at the front and rear of the spring tube. The guide shaft 33 is connected to the left support frame and the right support frame, respectively. The spring tube clamps the guide shaft 33. This eliminates gaps in the structure, further improving quality, and at the same time, makes adjusting the resistance easier and more convenient.

[0033] When the present invention is used in a back-folding flexible screen terminal, the flexible screen 400 is placed on the back of the mobile terminal. The left casing 100 and the left connecting member 51 are connected via screws. The right casing 200 is connected to the right connecting member 52. The flexible screen is fixedly connected to the left casing 100 and the right casing 200, respectively.

The support surface 10 of the flexible screen is located at a middle position. The left movable support plate 61 and the right movable support plate 62 are used as support members.

[0034] The above description is merely a best embodiment of the present invention, and does not limit the structural features of the present invention.
