1. A rollable display device, comprising:
a flexible display panel;
a storage mechanism, wherein a rotary component is disposed in the storage mechanism, the rotary component in the storage mechanism is configured to roll up the flexible display panel,
the storage mechanism is configured to store the flexible display panel that is rolled,
the rotary component comprises a rotary member and a rotating shaft member, the rotating shaft member is rotatably connected to the rotary member, and the rotating shaft member comprises a first rotating shaft and a second rotating shaft; and
an actuating mechanism fixedly connected to the storage mechanism, wherein the actuating mechanism comprises a first actuating component and a second actuating component, the storage mechanism is located between the first actuating component and the second actuating component, the first actuating component is fixedly connected to a first end of the flexible display panel, the second actuating component is fixedly connected to a second end of the flexible display panel; and
wherein the storage mechanism comprises a storage component, the storage component comprises a fixing member and a connection member, the actuating mechanism is fixedly connected to the fixing member, and the connection member is fixedly connected to the fixing member;
wherein the fixing member comprises a first fixing plate and a second fixing plate, the connection member comprises a first connection plate located on a side of the fixing member and a second connection plate located on another side of the fixing member;
wherein an end of the first connection plate is fixedly connected to the first fixing plate, another end of the first connection plate is fixedly connected to the second fixing plate, an end of the second connection plate is fixedly connected to the first fixing plate, and another end of the second connection plate is fixedly connected to the second fixing plate;
wherein the rotary member comprises a first rotary plate and a second rotary plate, the first rotary plate is rotatably connected to the first fixing plate, and the second rotary plate is rotatably connected to the second fixing plate;
wherein when the flexible display panel is in a completely rolled-up state, in a direction parallel to the first rotating shaft or the second rotating shaft, an orthogonal projection of the first rotary plate on the first fixing plate overlaps with the first fixing plate, and an orthogonal projection of the second rotary plate on the second fixing plate overlaps with the second fixing plate; and
wherein when the first actuating component and the second actuating component slide relative to each other, a rotation direction of the first rotating shaft is opposite to a rotation direction of the second rotating shaft, and at least one end of the flexible display panel moves away from or close to the storage mechanism.
