[0002] For the folding devices equipped with flexible screens in the current market, there are extremely high requirements for the linkage and support of the folding devices. In order to prevent the rotating hinge mechanism from exerting squeezing force on the flexible screen during the folding movement, the existing rotating hinge mechanism usually sets a floating plate at the folding part, and the floating plate can rise and fall with the folding and unfolding process. The existing folding screen floating plate lifting structure usually uses a lever structure to lift the floating plate. When the rotating hinge mechanism is folded, the position of the floating plate is not fixed, and it can also rise and fall within a small range relative to the whole machine. The floating plate is prone to position displacement, which causes the rotating hinge mechanism to have an undesirable sense of blockage when rotating. Utility Model Content

[0044] Please refer to Figures 1 to 5 Embodiment 1 of the utility model is: a folding screen floating plate 3 lifting structure, comprising a base 1, a swing arm 2, a floating plate 3 and a magnetic member 4; an arc-shaped connecting portion 21 is provided at one end of the swing arm 2, an arc-shaped hole 11 and a receiving groove 12 are provided on the base 1, the floating plate 3 is arranged in the receiving groove 12, the arc-shaped hole 11 cooperates with the arc-shaped connecting portion 21, and one end of the arc-shaped hole 11 is connected to the bottom of the receiving groove 12; a magnetic member 4 is provided on the bottom surface of the floating plate 3 or the receiving groove 12.

[0045] In this embodiment, a magnetic member 4 is provided on the bottom surface of the floating plate 3 and the receiving groove 12, and the polarities of the two magnetic members 4 are opposite and attract each other; there are two swing arms 2, and the arc-shaped holes 11 are arranged in a one-to-one correspondence with the number of swing arms 2, and the two swing arms 2 are symmetrically arranged with the floating plate 3 as the center; a mounting hole 22 is provided at one end of the swing arm 2 away from the arc-shaped connecting portion 21; and the magnetic member 4 is preferably a magnet. In other embodiments, the magnetic member 4 is arranged on the bottom surface of the floating plate 3, and the base 1 is made of a material that can be adsorbed by the magnetic member 4, or the magnetic member 4 is arranged on the bottom surface of the receiving groove 12, and the floating plate 3 is made of a material that can be adsorbed by the magnetic member 4.
