The first body 110 and the second body 120 can respectively drive the first portion 210 and the second portion 220 to be folded or unfolded, so that the electronic device 1000 can be in a folded or unfolded use state. The electronic device 1000 may be a mobile phone, a tablet computer, or a notebook computer.

The first body 110 is provided with a first bearing part 130, a first rotating part 140 which can slide relative to the first bearing part 130, and a first elastic part 150 which is elastically connected to the first bearing part 130 and the first rotating part 140. By using the elastic supporting force of the first elastic portion 150, the first bearing portion 130 and the first rotating portion 140 can be separated from each other and unfolded, so that the first bearing portion 130 can drive the first portion 210 of the flexible display screen 200 to be completely unfolded relative to the second portion 220, thereby preventing the flexible display screen 200 from being wrinkled and ensuring the effective bearing of the folding device 100 on the flexible display screen 200.

After the first main body 110 is unfolded relative to the second main body 120, the abutting force of the first elastic portion 150 on the first rotating portion 140 and the abutting force of the second elastic portion 180 on the second rotating portion 170 are cancelled, and the elastic abutting force of the first elastic portion 150 on the first bearing portion 130 is opposite to the elastic abutting force of the second elastic portion 180 on the second bearing portion 160, so that the first bearing portion 130 and the second bearing portion 160 are mutually repelled under the combined action of the first elastic portion 150 and the second elastic portion 180. The second bearing part 160 is fixedly connected to the second portion 220 of the flexible display screen 200, and the first bearing part 130 is fixedly connected to the first portion 210 of the flexible display screen 200.

The first bearing block 1945 and the second bearing block 1946 are arranged side by side along a length direction of the spindle body 190. The first shaft groove 1942 and the first bearing groove 1941 are provided to the first bearing block 1945. That is, the first rotating shaft 191 and the first rotating part 140 are rotatably connected to the first bearing block 1945.

second shafts

191 and 192 are synchronously rotated by the first, second, third and fourth gears. Of course, in other embodiments, the synchronous drive assembly 195 may be a link synchronous drive or a belt synchronous drive.

Further, referring to fig. 7, the first elastic portion 150 is provided with two repelling magnets 151, and the two magnets 151 are respectively fixed to the first bearing portion 130 and the first rotating portion 140.

In this embodiment, the magnet 151 may be a permanent magnet. The two magnets 151 are different in magnetic properties. The two magnets 151 always keep a repulsive state, that is, the magnetic repulsive force of the two magnets 151 forms an elastic abutting force of the first elastic portion 150 acting on the first bearing portion 130 and the first rotating portion 140. Namely, the first bearing part 130 and the first rotating part 140 always keep a repulsive state. When the first main body 110 is in an unfolded state or a folded state relative to the second main body 120, the first bearing portion 130 is always away from the first rotating portion 140, so that the flexible display screen 200 is always kept in an unfolded state, and the folding defect of the flexible display screen 200 in the unfolded or folded state is avoided. The second elastic portion 180 has substantially the same structure as the first elastic portion 150, and is not described herein again. The second elastic portion 180 applies a resisting force to the second bearing portion 160 and the second rotating portion 170 to ensure that the second bearing portion 160 and the second rotating portion 170 are always mutually repulsive, so as to drive the first portion 210 and the second portion 220 of the flexible display screen 200 to maintain a balanced and unfolded state, thereby ensuring the safety of the flexible display screen 200.

Further, referring to fig. 8, the first elastic portion 150 is further provided with a spring 152. Two ends of the spring 152 respectively abut against the first bearing portion 130 and the first rotating portion 140. The elastic force of the spring 152 is parallel to the repulsive force of the two magnets 151. The spring 152 is a rectangular spring. The spring 152 is always kept in an elastically compressed state, so that the first bearing part 130 is always kept in a repulsive state with respect to the first rotating part 140. The spring 152 can compensate the abutting acting force of the magnet 151 on the first bearing portion 130 and the first rotating portion 140 when the magnetism is lost, so as to ensure the mutual repulsion effectiveness of the first bearing portion 130 and the first rotating portion 140. The elastic force of the spring 152 may compensate the magnetic repulsive force of the two magnets 151, such that the force of the first elastic part 150 may be greater than the self-bending restoring stress of the flexible display 200. By compensating the acting force of the spring 152 to the two magnets 151, the magnetism of the magnets 151 can be reduced, and the magnetic property of the two magnets 151 can be prevented from generating electromagnetic interference on electronic components of the electronic device 1000. It is understood that the magnetic force of the two magnets 151 can also compensate the force of the spring 152, so as to prevent the spring 152 from failing elastically under the condition of multiple elastic compression or expansion, and avoid the failure of the force of the first elastic part 150, so as to ensure that the flexible display panel 200 can be unfolded effectively and flatly at all times. The second elastic part 180 is also provided with a spring 152 to ensure the effectiveness of the second elastic part 180.

In a preferred embodiment, the magnet 151 is an electromagnet. The magnet 151 may be electrically connected to a main board of the electronic device 1000 to receive a control signal of the main board of the electronic device 1000, so that the first elastic part 150 may apply an elastic force to the first bearing part 130 and the first rotating part 140 according to the control signal, and the second elastic part 180 may apply an elastic force to the second bearing part 160 and the second rotating part 170 according to the control signal. When the first body 110 is unfolded relative to the second body 120, the first elastic part 150 and the second elastic part 180 may receive a control signal of a main board, so that the magnet 151 generates magnetism, and the first bearing part 130 is separated relative to the first rotating part 140, and the second bearing part 160 is separated relative to the second rotating part 170, thereby realizing the separation of the flexible display 200. When the first main body 110 is overlapped with respect to the second main body 120, the first elastic portion 150 and the second elastic portion 180 may receive a control signal of the main board, so that the magnet 151 loses magnetism, and thus the first bearing portion 130 is driven by the bending stress of the flexible display screen 200 to be relatively close to the first rotating portion 140, and the second bearing portion 160 is driven by the bending stress of the flexible display screen 200 to be relatively close to the second rotating portion, so that the first elastic portion 150 and the second elastic portion 180 are prevented from obstructing the bending of the flexible display screen 200, and the folding smoothness of the electronic device 1000 is improved.

Further, with reference to fig. 8, the first bearing portion 130 is provided with a guide groove 133, the first rotating portion 140 is provided with a slider 141 slidably connected to the guide groove 133 and a rotating arm 142 fixedly connected to the slider 141, one end of the rotating arm 142 away from the slider 141 is rotatably connected to the second main body 120, and the two magnets 151 are respectively fixed to the side wall of the guide groove 133 and the slider 141.

In this embodiment, the guide groove 133 extends from the first connecting edge 132 toward the first free edge 131. The guide groove 133 communicates with the first arc groove 1321. The guide slot 133 is provided with a closed end remote from the first arcuate recess 1321 and an open end opposite the first closed end. The slider 141 can slide into the guide groove 133 from the open end. The guide groove 133 slidably guides the slider 141 substantially perpendicular to both sidewalls of the first connecting edge 132.
