That is, the folding mechanism 14 is utilized to drive the two shells to be unfolded or folded synchronously, so that folding and unfolding of the flexible display screen 13 can be realized, stress in the folding process of the flexible display screen 13 is more uniform, the service life of the flexible display screen 13 is prolonged, the flexible quality of the flexible display screen 13 is reduced, and further the cost of the foldable electronic device 10 is reduced.

Specifically, when the rotating member 200 rotates from the folded state to the unfolded state, the rotating member 200 drives the first housing 11 and the flexible display 13 to be unfolded relative to the second housing 12; in this process, the rotating member 200 drives the supporting member 400 to move from the avoiding state to the supporting state, when the rotating member 200 is in the unfolding state, if the rotating member continues to rotate in the opposite direction from the unfolding state to the folding state, the rotation stopping member will abut against the rotating member 200, so as to limit the rotating member 200 to rotate in the opposite direction from the unfolding state to the folding state, so that the first housing 11 and the second housing 12 are connected to form a flat plane, and the flexible display 13 is reliably supported by using the two supporting members 400, so that the flexible display 13 can be displayed flatly, and the display effect of the flexible display 13 in the unfolding state is improved. And when the rotation member 200 is required to rotate from the unfolding state to the folding state, the rotation member 200 drives the first shell 11 and the second shell 12 to synchronously approach each other, so that folding is realized, the two support members 400 are switched from the supporting state to the avoiding state, one support member 400 can be partially arranged towards the avoiding surface 101 direction of the first shell 11, and the other support member 400 can be partially arranged towards the avoiding surface 101 direction of the second shell 12, so that the two support members 400 can form a larger avoiding space 401 to avoid the flexible display screen 13 in the folding state, the bending stress of the flexible display screen 13 can be reduced, and the service life of the flexible display screen 13 is prolonged. The foldable electronic device 10 adopts the folding mechanism 14, has a simple and reliable structure, is easy to realize that the flexible display screen 13 can be switched between an unfolding state and a folding state, and reduces the cost of the foldable electronic device 10.
