[0029] The words expressing position and direction described in the utility model are all explained by taking the drawings as examples, but changes can also be made according to needs, and the changes made are all included in the protection scope of the utility model.

[0030] As Figures 1 to 5 shown, a folding screen hinge with floating plate provided by the utility model, comprising:

[0031] Pivot main body 1;

[0032] Floating plate 2, which is movably connected with the pivot main body 1, the end of the floating plate 2 is provided with an arc-shaped slot 21;

[0033] Swing arm piece 3 for driving the screen support plate 4 to overturn, the swing arm piece 3 includes a main part 31 and a cantilever part 32 fixedly connected with the main part 31, the main part 31 is connected to the pivot main body 1 and can swing relative to the pivot main body 1;

[0034] Connecting piece 5, one end of which is connected with the cantilever part 32, and the other end is slidably connected in the arc-shaped slot 21, the connecting piece 5 is configured to be able to slide in the arc-shaped slot 21 along with the swing of the cantilever part 32, so as to drive the floating plate 2 to move up and down relative to the pivot main body 1.

[0035] In the embodiment, the screen support plate 4 is used for supporting the flexible screen 6, the screen support plate 4 is fixedly connected with the swing arm 3, the screen support plate 4 is driven to turn over by the swing arm 3, and then the folding or unfolding of the flexible screen 6 is realized; when the flexible screen 6 is in the unfolded state, the floating plate 2 and the screen support plate 4 are flush, so that a flat support surface can be provided to support the flexible screen 6, and the obvious folding mark of the flexible screen 6 is avoided. When the flexible screen 6 is in the folded state, the floating plate 2 is floated downwards to avoid the folding bottom of the flexible screen 6. When the swing arm 3 turns over relative to the rotating shaft main body 1, the cantilever part 32 of the swing arm 3 drives the adaptive relative sliding of the connecting piece 5 and the arc-shaped groove 21, and then the floating plate 2 is driven to float upwards and downwards by the connecting piece 5, so that the effect of supporting or avoiding the flexible screen 6 is achieved.

[0036] The floating plate 2 and the swing arm 3 are assembled through the matching structure of the connecting piece 5 and the arc-shaped groove 21, the floating plate 2 is floated upwards and downwards through the turning over of the swing arm 3, and the structure is simple, and the assembly difficulty of the floating plate 2 is greatly reduced.

[0037] As a preferred embodiment, the cantilever part 32 is provided with an assembly hole 33 and a notch 34 in communication with the assembly hole 33, and one end of the connecting piece 5 is inserted into the assembly hole 33.

Since the notch 34 is arranged, the assembly hole 33 can be elastically expanded adaptively, which can reduce the assembly difficulty on one hand and can adapt to the diameter size of the connecting piece 5 on the other hand. In this way, the size precision requirement of the connecting piece 5 can be reduced, and the diameter size of the connecting piece 5 can be allowed to be larger than the preset size. In addition, after the elastic expansion of the assembly hole 33, the assembly hole 33 clamps the connecting piece 5 through the deformation elastic force, so that the connecting piece 5 and the assembly hole 33 do not shake due to the large gap therebetween, and the movement precision is affected.

[0039] As a preferred embodiment, the caliber of the notch 34 is smaller than the diameter of the assembly hole 33. In this way, the connecting piece 5 is prevented from easily separating from the notch 34, and the reliability of the connection between the connecting piece 5 and the cantilever part 32 is ensured.
