When the flexible screen support mechanism 110 is pulled out of the winding drum 130, one end of the rotating component 102 away from the winding shaft 140 in the first state abuts against the first inclined surface 261, the rotating component 102 receives a reverse acting force from the first inclined surface 261, and one side of the rotating component 102 is connected with the support component 101, so that the end of the rotating component 102 away from the support component 101 is turned from the first state to the second state under the reverse acting force from the first inclined surface 261.

In the process of winding the flexible screen support mechanism 110 on the winding shaft 140, one end of the rotating member 102 in the second state close to the winding shaft 140 abuts against the second inclined surface 271, and the rotating member 102 receives a reverse acting force from the second inclined surface 271, and because one side of the rotating member 102 is connected with the support member 101, the rotating member 102 can be turned from the second state to the first state under the reverse acting force from the second inclined surface 271.

In one embodiment of the present application, the first inclined surface 261 is provided on the first housing 21, and the second inclined surface 271 is provided on the second housing 22.

In one embodiment of the present application, the rollable electronic device 100 further includes a roll synchronization mechanism, a flexible screen tensioning mechanism, and a reel power transmission mechanism (not shown).

In one embodiment of the present application, the flexible screen support mechanism 110 may be wound into the roll 130 or pulled out of the roll 130 manually or automatically by a driving device (not shown).

In one embodiment of the present application, the rollable electronic device 100 can be any rollable terminal device with a flexible screen, including but not limited to a television, a tablet computer, a notebook, and the like.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
