The second supporting plate 220 is fixedly connected to the second mounting plate 121, for example, the two are fixed by screws 101 in a threaded manner, and can also be fixed by welding, clamping, riveting or gluing in a detachable or non-detachable manner. When the first rotating shaft 110 and the second rotating shaft 120 rotate relative to the intermediate rotating shaft 130, the first supporting plate 210 and the second supporting plate 220 rotate relative to the intermediate rotating shaft 130 at the same time, so that the foldable electronic device 10 can be switched between the folded state and the unfolded state.
The first support plate 210 includes a front 211, a back 212, and sides 214; the second support plate 220 includes a front surface 221, a rear surface 222, and side surfaces 224. For the first support plate 210 and the second support plate 220, the front surface 211(221) and the back surface 212(222) are disposed opposite to each other. The front side 211(221) refers to a surface of the display area 301 facing the flexible display panel 300, that is, the front side 211(221) is closer to the display area 301 of the flexible display panel 300 than the back side 212(222), and obviously, the display area 301 is located on a side where the front side 211(221) is located, and the side surfaces 214(224) are connected between the front side 211(221) and the back side 212 (222).

Referring to fig. 7 to 10, in some embodiments, the side surface 214 of the first supporting plate 210 abuts against the first rotating shaft 110, and the side surface 224 of the second supporting plate 220 also abuts against the second rotating shaft 120, so that the first supporting plate 210 abuts against the first rotating shaft 110, and the second supporting plate 220 abuts against the second rotating shaft 120, thereby minimizing a gap between the first supporting plate 210 and the first rotating shaft 110 and a gap between the second supporting plate 220 and the second rotating shaft 120, preventing the flexible display 300 from being recessed and collapsed at the gap, and further ensuring the flatness of the flexible display 300.
Referring to fig. 4, 6 and 7, in some embodiments, in the unfolded state, the front surface 211 of the first support plate 210 and the front surface 221 of the second support plate 220 are flush with each other, in other words, the front surfaces 211, 221 of both the first support plate 210 and the second support plate 220 are in the same plane. The first shaft 110, the second shaft 120 and the middle shaft 130 have a common tangent plane, and the front surfaces 211 and 221 of the first support plate 210 and the second support plate 220 are flush with the tangent plane. Therefore, the first support plate 210, the second support plate 220, the first rotating shaft 110, the second rotating shaft 120 and the middle rotating shaft 130 can simultaneously support the flexible display screen 300, excessive gaps between the flexible display screen 300 and the rotating shaft assembly 100 and between the flexible display screen 300 and the support assembly 200 are avoided, and the flexible display screen 300 is prevented from sinking and collapsing.
Referring to fig. 2 and 3, the flexible display screen 300 has a first end 310, a second end 320, and a display area 301, wherein the first end 310 and the second end 320 are disposed opposite to each other, and the display area 301 is connected between the first end 310 and the first end 310. The display area 301 of the flexible display screen 300 is spanned on the first rotating shaft 110, the second rotating shaft 120 and the middle rotating shaft 130, the first end 310 of the flexible display screen 300 is connected with the first supporting plate 210, the second end 320 of the flexible display screen 300 is connected with the second supporting plate 220, the middle part of the display area 301 corresponds to the rotating shaft assembly 100, the part of the display area 301 close to the first end 310 is arranged on the front 211 of the first supporting plate 210 in a stacking mode, and the part of the display area 301 close to the second end 320 is arranged on the front 221 of the second supporting plate 220 in a stacking mode.
When the rotating shaft assembly 100 drives the supporting assembly 200 to rotate so as to switch the foldable electronic device 10 between the folded state and the unfolded state, the intermediate rotating shaft 130 is not moved, the relative position of the first supporting plate 210 and the first rotating shaft 110 is kept unchanged, and the relative position of the second supporting plate 220 and the second rotating shaft 120 is kept unchanged. When the first rotating shaft 110 and the second rotating shaft 120 rotate, the first supporting plate 210 and the second supporting plate 220 do fixed-axis rotation relative to the external shaft (i.e. the middle rotating shaft 130) and avoid the fixed-axis rotation relative to the internal shaft, therefore, the first supporting plate 210 and the second supporting plate 220 cannot be bent all the time, so as to maintain sufficient rigidity, and further form a good supporting function for the flexible display screen 300 stacked thereon, and avoid a large gap from being formed between the front 211, 221 of the first supporting plate 210 and the second supporting plate 220 and the flexible display screen 300, so that the display areas 301 corresponding to the first supporting plate 210 and the second supporting plate 220 on the flexible display screen 300 are kept flat, and the generation of depression and collapse is avoided, and the display effect of the flexible display screen 300 is ensured.
In some embodiments, the first end 310 of the flexible display screen 300 is fixedly connected with the first support plate 210. The fixed connection mode can adopt various modes such as bonding, riveting, welding and the like. When the flexible display panel is fixed by bonding, a glue may be directly disposed between the flexible display panel 300 and the first support plate 210. When the flexible display screen 300 is fixed by riveting, welding or the like, a suitable connecting member may be disposed on the first end 310 of the flexible display screen 300, and then riveting, welding or the like may be performed on the first supporting plate 210 through the connecting member. The second end 320 of the flexible display 300 is elastically connected to the second support plate 220. The elastic connection between the flexible display screen 300 and the second supporting plate 220 enables the flexible display screen 300 to be under elastic tension in the switching process between the folded state and the unfolded state, so that the flexible display screen 300 does not have local concave and uneven phenomena in the switching process. In addition, since a length difference is generated between the side surface of the flexible display 300 and the side surface of the housing assembly 400 during the switching process between the folded and unfolded states of the foldable electronic device 10, the length difference can be changed by the elastic connection of the flexible display 300.
Referring to fig. 2 and 3, in some embodiments, the elastic tension between the second end 320 and the second supporting plate 220 is obtained by disposing an elastic member 330 between the second end 320 of the flexible display screen 300 and the second supporting plate 220. In one embodiment, the elastic member 330 is a strip, and may be an elongated member made of steel, for example. Both ends of the elastic member 330 are connected to the second end 320, and the middle portion of the elastic member 330 is connected to the second support plate 220. For example, a fixing post 340 may be provided on the second support plate 220 for positioning the elastic member 330. Specifically, the middle of the elastic member 330 may be disposed on one side of the fixed column 340, and both ends of the elastic member 330 are connected to the second end 320 of the flexible display 300, and the flexible display 300 pulls the elastic member 330 toward the other side of the fixed column 340, so that the elastic member 330 is elastically deformed when the electronic device is switched between the folded state and the unfolded state. Meanwhile, the flexible display 300 is under tension, so that the flexible display 300 does not collapse or sag.
