As shown in fig. 8 to 10, in the relative rotation process of the bracket, when the bracket is unfolded, and the screen on the bracket is unfolded by 180 °, the sliding

31 generates a rotation friction force and a damping effect under the action of the spring force, so that hovering during bending is realized, and the hand feeling during bending is softer. When the mobile phone is bent by 180 degrees, the mobile phone is bent to half size, due to the connection effect of the rotating assembly, the frame body is pushed to slide to the middle area, the

30 is driven to rotate, the

30 rotates to be located in the shortest diameter area, the shortest diameter area of the

30 abuts against one end of the sliding

31, and the extra screen length is accommodated and absorbed when the screen is bent back; when the mobile phone is unfolded, the

30 rotates to be located in the maximum diameter area, the maximum diameter area of the

30 abuts against one end of the sliding

31, and the sliding

31 drives the frame bodies to move, so that the relative space between the two frame bodies is increased to accommodate the screen.

In the use process, when the device (such as a mobile phone) with the folding mechanism is unfolded to bend the screen reversely, the

12 rotates to drive the

30 to rotate, the sliding

31 is always in surface contact with the

30 under the action of the spring force, the

30 rotates to push the sliding

31 to move linearly, and then the

41 and the

51 are pushed to retract in a sliding mode, and the sliding

31 and the corresponding frame bodies are fixed to move together, so that the length of the screen in the folding process is reduced. When the bent mobile phone is bent to a flat screen, the

12 rotates to drive the

30 to rotate, the sliding

31 is always in contact with the surface of the

30 under the action of the spring force, the

30 rotates to push the sliding

31 to move linearly, and the sliding

31 and the corresponding frame body are fixed to move together, so that the frame body is pushed to slide relative to the hinge support where the frame body is located, the length increased when the screen is unfolded is accommodated, and the flat unfolding of the screen is realized. Because the

31 promotes the support body to slide when the

30 rotates, can realize the extension of screen bending length and change, can not produce the power of dragging to the screen, the screen life-span of bending increases, and is difficult to lead to the screen and the clearance increase of structure all around.

In some embodiments, the movement direction of the sliding

31 is perpendicular to the

12, so that the sliding

31 can move stably, and the stability during the folding process can be ensured.

Optionally, as shown in fig. 1, the rotating assembly further includes a

70, the

10 and the

20 are pivoted by the

70, the

70 has a supporting function, and can support a middle area of the screen when the screen is unfolded, so that the user does not sink when pressing the screen and the touch experience is not affected.
