1. A support structure for supporting a flexible display screen, comprising a support component and a synchronous transmission component, wherein:
the support component comprises two telescopic rods, and has a fixed side fixed relative to a fixed side edge of the flexible display screen, and a movable side extendable and retractable with expansion or winding of a movable side edge of the flexible display screen; and
the synchronous transmission component is connected to the support component, and is configured to move ends of the two telescopic rods on the movable side of the support component synchronously in a direction parallel to the movable side edge of the flexible display screen,
wherein each of the telescopic rods comprises a plurality of sub-links hinged end to end and having the same length; and the sub-links of the two telescopic rods are hinged in a one-to-one correspondence manner with a hinged position located at a central position of the two hinged sub-links; and
two ends of each telescopic rod are respectively used as the fixed side and the movable side,
wherein the synchronous transmission component comprises two synchronization groups and two transmission groups, wherein
one of the synchronization groups is connected to the fixed sides of the two telescopic rods, and the other of the synchronization groups is connected to the movable sides of the two telescopic rods; each of the synchronization groups comprises a fixed member and two movable members, wherein the ends of the two telescopic rods are connected to the fixed member in a relatively movable manner, and a direction of the relative movement is parallel to the movable side edge of the flexible display screen; the two movable members are respectively hinged to the ends of the two telescopic rods that are connected to the fixed member; and
the two transmission groups are respectively disposed on the fixed members in the two synchronization groups, and each of the transmission groups comprises a transmission member that is connected to the two movable members in a relatively movable manner and configured to move the two movable members synchronously in the direction parallel to the movable side edge of the flexible display screen,
wherein each of the movable members comprises a rack, and the transmission member comprises at least one gear disposed between and engaged with two opposite racks, wherein both of the racks are parallel to the direction of the movable side edge of the flexible display screen and respectively integrated with the two movable members.
