During the bending process of the hinge device 25, each rotating shaft 27 rotates relative to the corresponding damping hole 281, specifically, the first engaging surface 2732 of the rotating shaft 27 is disengaged from the corresponding first positioning surface 282, the side of the second engaging surface 2734 of the rotating shaft 27 away from the connecting portion 287 is disengaged from the corresponding second receiving groove 2831, and the outer peripheral surface of the rotating shaft 27 is engaged with the arc surface of the second receiving groove 2831. The positioning section 273 of the rotating shaft 27 rotates in the corresponding damping hole 281, the outer peripheral surface of the positioning section 273 pushes against the inner peripheral surfaces of the first clamping strip 2853 and the second clamping strip 2858, so that the first elastic shoulder 2850 and the second elastic shoulder 2855 of the elastic positioning ring 285 elastically deform and are away from each other, the aperture of the damping hole 281 is enlarged, the first clamping strip 2853 and the second clamping strip 2858 of the elastic positioning ring 285 are away from each other, and the damping force of the elastic positioning ring 285 of the damping piece 28 on the positioning section 273 of the rotating shaft 27 is increased; until the second matching surface 2734 of the rotating shaft 27 is fitted to the second positioning surface 283, the first elastic shoulder 2850 and the second elastic shoulder 2855 elastically return to press the outer peripheral surface of the positioning section 273 of the rotating shaft 27, and the aperture of the damping hole 281 returns to the initial size.

The hinge means 25 completes the bending and the flexible screen 30 is bent with the hinge means 25. The front faces of the first hinge 262, the two second hinge 264 and the two third hinge 265 have a circular arc surface to facilitate the attachment of the flexible screen 30, and the damping member 28 can stably maintain the hinge device 25 in a bent state.
When the electronic device 100 needs to be unfolded, the first frame body 21 and the second frame body 23 are pulled outwards, so that the third hinges 265 connected to the first frame body 21 and the second frame body 23 rotate in the direction away from each other, the rotating shafts 27 connected to the third hinges 265 rotate relative to the corresponding second hinges 264, and the third hinges 265 rotate relative to the corresponding second hinges 264 towards one side of the flexible screen 30; the rotation of the gear assembly 293 can drive the second hinge joint 264 and the damping member 28 to rotate relative to the first hinge joint 262, so that the second hinge joint 264 is bent towards one side of the flexible screen 30 relative to the first hinge joint 262 until the hinge device 25 is flattened. In the process of flattening the hinge device, each of the rotating shafts 27 rotates in the corresponding damping hole 281, specifically, the second matching surface 2734 of the rotating shaft 27 is separated from the corresponding second positioning surface 283, the side edge of the first matching surface 2732 of the rotating shaft 27 away from the connecting portion 287 is separated from the corresponding first receiving slot 2821, the positioning section 273 of the rotating shaft 27 rotates in the corresponding damping hole 281, the outer peripheral surface of the positioning section 273 abuts against the inner peripheral surfaces of the first clamping strip 2853 and the second clamping strip 2858, so that the first elastic shoulder 2850 and the second elastic shoulder 2855 of the elastic positioning ring 285 elastically deform and are separated from each other to enlarge the aperture of the damping hole 281, the first clamping strip 2853 and the second clamping strip 2858 of the elastic positioning ring 285 are separated from each other to increase the damping force of the elastic positioning ring 285 of the damping member 28 on the outer peripheral surface 273 of the rotating shaft 27 until the first matching surface 2732 of the rotating shaft 27 abuts against the first positioning surface 282, the first elastic shoulder 2850 and the second elastic shoulder 2855 elastically return to press the positioning section 273 of the rotating shaft 27, the diameter of the orifice 281 is reset to the original size.

In any bending state of the hinge device 25 from the flat state to the completely bent state, since the damping force is applied between the damping member 28 and the rotating shaft 27, the hinge device 25 can be positioned in any bending state without an external force, that is, the damping member 28 can position the hinge device 25 at any bending position.
