[0033] The first supporting component 100 is used to support a part of the flexible display screen 800 .

[0034] The second supporting component 200 is used to support another part of the flexible display screen 800 .

[0035] The base 500 is rotatably connected to the first bearing assembly 100 and the second bearing assembly 200 .

[0036] The first movable component 300 is a telescopic structure. One end of the first movable component 300 is rotatably connected to the first bearing component 100 , and the other end of the first movable component 300 is rotatably connected to the base 500 .

[0037] The second movable component 400 is a telescopic structure. One end of the second movable component 400 is rotatably connected to the second bearing component 200 , and the other end of the second movable component 400 is rotatably connected to the base 500 .

[0038] When the first supporting component 100 is flipped relative to the second supporting component 200 to bend the flexible display screen 800, the first supporting component 100 and the second supporting component 200 respectively drive the first movable component 300 and the second movable component 400 to rotate and unfold, and a receiving space is formed between the first movable component 300, the second movable component 400 and the base 500, and the receiving space receives the bent part of the flexible display screen 800 after bending.

[0039] It can be understood that after the first bearing assembly 100 and the second bearing assembly 200 drive the flexible display screen 800 to fold, the foldable portion of the flexible display screen 800 is not completely closed and folded, and the foldable portion of the flexible display screen 800 roughly forms a water drop-shaped structure. The first movable assembly 300 and the second movable assembly 400 rotate and unfold, and the first movable assembly 300 and the second movable assembly 400 are inclined and close to each other, and the first movable assembly 300, the second movable assembly 400 and the base 500 are roughly in a triangular structure. A receiving space is formed between the first movable assembly 300, the second movable assembly 400 and the base 500, and the receiving space receives the roughly water drop-shaped curved portion of the flexible display screen 800.

[0040] It is understandable that the foldable electronic device 900 can be unfolded or brought close to each other by the first supporting component 100 and the second supporting component 200 to drive the flexible display screen 800 to fold or unfold, thereby achieving two usage states.

The length direction of the first rotating arm 120 is substantially perpendicular to the first connecting edge 12. One end of the first rotating arm 120 is rotatably connected to the base 500. The two first rotating arms 120 respectively drive the two ends of the first bearing member 110 to rotate relative to the second bearing member 210, so that the first bearing member 110 rotates relatively to the second bearing member 20 in a balanced manner. One end of the first rotating arm 120 away from the base 500 is connected to the first support member 310, so as to facilitate the contraction of the first support member 310 relative to the first bearing member 110.

[0043] In this embodiment, the second supporting assembly 200 includes a second supporting member 210. The second supporting member 210 includes a second free edge 211 and a second connecting edge 212 disposed relative to the second free edge 211. The second connecting edge 212 is adjacent to the base 500. A portion of the flexible display screen 800 away from the first supporting member 110 is unfolded from the second connecting edge 212 to the second free edge 211, so as to facilitate the use of the second supporting member 210 to stably support a portion of the flexible display screen 800.

[0044] The second bearing assembly 200 includes a second rotating arm 220 fixedly connected to the second bearing member 210.

The two second rotating arms 220 are arranged opposite to each other. The two second rotating arms 220 are respectively near the two ends of the second connecting edge 212. The length direction of the second rotating arm 220 is substantially perpendicular to the first connecting edge 212. One end of the second rotating arm 220 is rotatably connected to the base 500. The two second rotating arms 220 respectively drive the two ends of the second bearing member 210 to rotate relative to the first bearing member 110, so that the second bearing member 210 rotates relatively to the first bearing member 110 in a balanced manner. One end of the first rotating arm 120 away from the base 500 is connected to the first support member 310, so as to facilitate the contraction of the first support member 310 relative to the first bearing member 110.

[0045] In this embodiment, the first movable component 300 includes a first support member 310 connected to the first rotating arm 120 and a first rotating member 320 slidably connected to the first support member 310. The first support member 310 includes a first movable edge 311 and a first sliding edge 312 arranged relative to the first movable edge 311, and two first side edges 313 connected between the first movable edge 311 and the first sliding edge 312.

The first support member 310 is slidably connected to the first rotating member 320 at the first sliding edge 312. The first support member 310 is connected to the first rotating arm 120 at the first side edge 313 close to the first movable edge 311. The portion from the first movable edge 311 to the first sliding edge 312 forms a structure supporting the flexible display screen 800. The first support member 310 is generally in the shape of a plate to increase the proportion of the supporting area of ​​the flexible display screen 800.

[0046] In this embodiment, the second movable component 400 includes a second support member 410 connected to the second rotating arm 220 and a second rotating member 420 slidably connected to the second support member 410.

The second support member 410 is slidably connected to the second rotating member 420 at the second sliding edge 412. The second support member 410 is connected to the second rotating arm 220 at the second side edge 413 close to the second movable edge 411. The portion from the second movable edge 411 to the second sliding edge 412 forms a structure supporting the flexible display screen 800. The second support member 410 is generally in the shape of a plate to increase the proportion of the supporting area of ​​the flexible display screen 800. When the first supporting member 110 is flipped relative to the second supporting member 210 to unfold the flexible display screen 800, the first rotating member 320 slides and contracts relative to the first supporting member 310, and the second rotating member 420 slides and contracts relative to the second supporting member 410 to drive the base 500 to partially support the flexible display screen 800.

[0047] When the first bearing member 110 and the second bearing member 210 are close to each other, the first movable edge 311 and the second movable edge 411 are close to each other along with the first rotating arm 120 and the second rotating arm 220, respectively, and the base 500 is present between the first sliding edge 312 and the second sliding edge 412, and there is a distance between the first sliding edge 312 and the second sliding edge 412. That is, the first supporting member 310 is driven by the first bearing member 110, and the second supporting member 410 is driven by the second bearing member 210, so that the first supporting member 310 is unfolded relative to the first rotating member 320, and the second supporting member 410 is unfolded relative to the second rotating member 420. A large receiving space is provided between the first supporting member 310 and the second supporting member 410, and the receiving space is used to accommodate the curved portion of the flexible display screen 100, so that the first supporting frame 310 and the second supporting member 410 can reduce the curvature of the flexible display screen 100.

[0048] When the first bearing member 110 is unfolded relative to the second bearing member 210, the first supporting member 310 slides and shrinks relative to the first rotating member 320, and the second supporting member 410 slides and shrinks relative to the second rotating member 420. The first supporting member 310 and the second supporting member 320 are flush with each other, and the first supporting member 310 and the second supporting member 320 are respectively moved closer to the two sides of the base 500 to support the flexible display screen 800.
