Abstract
The present disclosure discloses a flexible display device. The flexible display device includes a housing, a telescopic assembly, a flexible screen, and a transmission assembly. Both ends of the flexible screen are connected to the telescopic assembly. The transmission assembly is disposed on the telescopic assembly and movably connected to the housing. The transmission assembly is configured to drive, during the movement relative to the housing, the telescopic assembly to stretch or contract. In this way, the flexible screen is pulled out or rolled for storage.
Claims16
A flexible display device, comprising:
- a housing;
- a telescopic assembly comprising a first support portion disposed on the housing, a second support portion movably connected to the first support portion, and a rotary receiving portion disposed in the second support portion;
- a flexible screen disposed on the telescopic assembly, and having one end connected to the first support portion and another end connected to the rotary receiving portion;
- and a transmission assembly disposed on the second support portion, and having one end movably connected to the housing and another end drivingly connected to the rotary receiving portion, wherein the transmission assembly comprises at least one first transmission member and at least one second transmission member which are provided on the second support portion and movably connected to the housing, one end of each first transmission member is drivingly connected to one corresponding second transmission member, and another end of the each first transmission member is drivingly connected to the rotary receiving portion;
- the first transmission member comprises a screw rod structure, the screw rod structure comprises a screw rod and a sleeve member sleeved on the screw rod, and the sleeve member is fixed on the housing,
- wherein the screw structure rotates while moving relative to the housing, the transmission assembly and is configured to drive the second support portion to move relative to the first support portion and drive the rotary receiving portion to rotate with movement of the transmission assembly relative to the housing to switch the flexible display device between a first state and a second state, and wherein an area of the flexible screen on the first support portion and the second support portion in the first state is less than an area of the flexible screen on the first support portion and the second support portion in the second state.
