Compare with current LED roller shutter screen, the beneficial effects of the utility model reside in that: can realize that flexible display screen 2's book contracts to accomodate and expand and show, and can remove to can realize removing and put in multimedia content from this, but wide application in different application scenes, like temporary classroom, meeting room, the portable indoor and outdoor cinema that removes, remove interim traffic sign etc..
Alternatively, as shown in fig. 8-9, in the present embodiment, the flexible display screen 2 includes a plurality of display modules 21 arranged along the curling direction thereof, and the adjacent display modules 21 are electrically connected by the hair flexible flat cable 24. The front surfaces of the adjacent display modules 21 are connected through a flexible steel mesh 22, the back surfaces of the adjacent display modules 21 are connected through at least two flexible connecting sheets 23, two ends of each flexible connecting sheet 23 are connected to the two adjacent display modules 21, one end of each flexible connecting sheet is fixed on one of the display modules, the other end of each flexible connecting sheet is provided with a waist-shaped hole 23a arranged along the arrangement direction of the display modules, and the flexible connecting sheets are fixed on the other display module through screws which transversely penetrate through the waist-shaped holes 23 a. When the lifting mechanism 3 drives the flexible display screen 2 to ascend and expand, the flexible connecting sheet 23 is straightened along the arrangement direction of the display module; when the rolling mechanism 4 drives the flexible display screen 2 to roll and contract in the aviation case, the flexible connecting sheet 23 bends along the arrangement direction of the display module, and slides relative to the screw.
When the lifting mechanism 3 vertically expands outwards, the flexible display screen 2 is driven to extend out of the aviation case 1, and the flexible display screen 2 is straightened under the driving force of the lifting mechanism 3 and the elastic force of the winding mechanism 4. When the lifting mechanism 3 is folded towards the inside of the aviation case 1, the flexible display screen 2 can be rolled on the rolling mechanism 4 under the action of the elastic restoring force of the rolling mechanism 4.
In addition, the flexible display screen 2 can be transversely spliced into a large screen, specifically, as shown in fig. 10, connecting plates 25 are arranged on two sides of each display module 21, and transversely adjacent display modules 21 can be connected together through the connecting plates to form a display screen with a larger and wider display range, so that the viewing effect is improved.
To perform the winding action of the winding mechanism 4, as shown in fig. 5-6, in the present embodiment, the winding mechanism 4 includes a fixed shaft 41, a roller 42 and two torsion springs 43. Both ends of the fixed shaft 41 are fixed in the flight case 1 through the bracket plates 411. The roller 42 is rotatably sleeved on the fixed shaft 41, and the rolling side of the flexible display screen 2 is connected to the outer periphery side of the roller 42. The two torsion springs 43 are respectively sleeved on the fixed shaft 41, one end of each torsion spring 43 is fixed on the fixed shaft 41, and the other end of each torsion spring 43 is fixed on the inner side of the roller 42.
When the lifting mechanism 3 drives the flexible display screen 2 to extend outwards, the roller 42 is synchronously driven to rotate relative to the fixed shaft 41, and the torsion spring 43 is sequentially deformed, so that the torsion spring 43 provides an elastic force opposite to the rising driving force of the lifting mechanism 3, and the flexible display screen 2 is straightened between the lifting mechanism 3 and the winding mechanism 4 and gradually expands outwards until the lifting mechanism 3 is completely expanded; when the lifting mechanism 3 is folded into the flight box 1, the flexible display screen 2 is gradually rolled by the roller 42 in the flight box 1 under the elastic force of the torsion spring 43 until the lifting mechanism 3 is completely folded into the flight box 1. Therefore, the flexible display screen 2 can be straightened when the flexible display screen 2 is unfolded, and the flexible display screen 2 can be rolled and contracted in the air box 1 when the flexible display screen is stored.
