The first and second drive racks 320 and 330 are each engaged with the drive gear 310 such that rotation of the drive gear 310 simultaneously drives the first and second drive racks 320 and 330. The first driving rack 320 is located on a first side of the driving gear 310, the second driving rack 330 is located on a second side of the driving gear 310, and the first side and the second side are opposite to each other, so that the driving gear 310 can simultaneously drive the first driving rack 320 and the second driving rack 330 to move in opposite directions.
Therefore, through the cooperation of the driving gear 310, the first driving rack 320 and the second driving rack 330, and the above arrangement, it can be achieved that the driving gear 310 simultaneously drives the first driving rack 320 and the second driving rack 330 to move in opposite directions, and thus drives the two ends of the flexible screen 200 to move in opposite directions.
The device housing 100 includes a first housing portion 110 and a second housing portion 120, the first housing portion 110 and the second housing portion 120 are relatively movable, the driving device 300 is disposed in the device housing 100, and the first driving rack 320 is connected to the first housing portion 110.

When the first housing portion 110 moves and the second housing portion 120 does not move, the first driving rack 320 is connected to the first housing portion 110, and the first housing portion 110 can be moved by the first driving rack 320. If the second housing part 120 does not move, the second housing part 120 does not have a driving structure. The second driving rack 330 may be movably engaged with the second housing portion 120, that is, the second driving rack 330 and the second housing portion 120 do not affect each other, and the second driving rack 330 is connected to the second end of the flexible screen 200 to drive the second end of the flexible screen 200 to move.
