The lower cover assembly 114 can be made of metal or plastic.

Referring to FIG. 6, the flexible display device 100 includes a spool 113 disposed within a housing 104, one end of which is coupled to the spool 113. The outer surface of the casing 104 is provided with a button 115. The reel 113 is provided with a motor (not shown). The button 115 is connected to the motor, and the motor rotates to drive the reel 113 to rotate. As such, the flexible display screen 102 can be wound up by the reel 113, so that the flexible display device 100 can be kept compact. The button 115 facilitates the user to operate the flexible display device 100 to switch back and forth between the unfolded state and the retracted state.

It can be appreciated that the support structure 106 can drive the flexible display screen 102 to retract relative to the housing 104 to switch back and forth between the deployed state and the retracted state. When the flexible display screen 102 is in the retracted state, the rear cover 116 can be manually pulled to drive the extension of the lower cover assembly 114 and the slide rail assembly 108. Since the support plate 118 is affixed to the flexible display screen 102, the support plate 118 is fixed to the slide rail assembly 108 by the fixing member 120 (magnetic member), and the support structure 106 can drive the flexible display screen 102 to extend relative to the housing 104. When the flexible display screen 102 is in the unfolded state, the rotation of the motor is controlled by the button 115 to drive the reel 113 to rotate to crimp the flexible display screen 102 relative to the housing 104. When it is to be noted, the rail block 110 at both ends of the rail assembly 108 is provided with a fixing member 120 for adsorbing and fixing the support plate 118, and the magnetic attraction of the fixing member 120 on the rail block 110 of the housing 104 to the support plate 118 is adsorbed. The force is less than the force of the motor to crimp the flexible display screen 102, and the magnetic attraction force of the fixture 120 on the rail block 110 away from the housing 104 to the support plate 118 is greater than the force of the motor to crimp the flexible display screen 102. Thus, when the flexible display screen 102 is crimped, the shrinkage of the slide rail assembly 108 and the lower cover assembly 114 can be driven, and the support panel 118 can be simultaneously curled with the flexible display screen 102. Preferably, one end of the support plate 118 can be fixed to the first plate 166 of the first slide block 124 to prevent the support plate 118 from separating from the slide assembly 108 when the flexible display screen 102 is crimped, thereby causing the support structure 106. It cannot be shrunk as the flexible display screen 102 is crimped. As such, it can be ensured that the support plate 118 and the rail assembly 108 are not separated.

In some embodiments, a control element (not shown) is provided in the housing 104 for controlling the flexible display device 100.
