- the pulling force on the pulling rope 81 reaches the maximum.
- the pulling force also reaches the maximum, which is greater than the suction force between the first magnet 66 and the second magnet 76 , so that the pulling rope 81 pulls the moving member 7 to move in the through hole 62 , so that one moving member 7 is located on the two sides of the two adjacent support bars 61 .
- the side of the protruding portion 75 away from the reel 2 is in contact with the side of the other boss 65 close to the reel 2.
- the boss 65 contacts the protruding portion 75 to limit the moving distance of the moving member 7, so that the supporting member 6 is formed such that a rigid plane cannot be bent to support the flexible display panel 1 .
- the user turns the handle 53 to make the pawl 52 disengage from the ratchet 51, and then releases the support 6 and the flexible display panel 1.
- the reel 2 rotates, thereby The support 6 and the flexible display panel 1 are driven to retract and wrap around the reel 2.
- the first scroll spring 822 drives the reel 821 to rotate, thereby driving the pull cord 81 to retract and wrap around the reel 821.
- the first scroll spring The torsional force of 822 gradually decreases.
- the attraction force between the first magnet 66 and the second magnet 76 is greater than the torsion force of the first scroll spring 822, the first magnet 66 and the second magnet 76 are attracted, so that a moving part 7 can be completely located in the through hole 62 of a support bar 61 to complete the winding of the flexible display device.
- the moving part 7 can be automatically adjusted by the pulling rope 81 and the pulling rope retractor 82, and the second scroll spring 4 can realize automatic winding after use, which does not require manual operation by the user, which is very convenient.
- the terms “a”, “an”, “the” and “said” are used to indicate the presence of one or more elements/components/etc.; the terms “comprising”, “including” and “having” are used for Indicates an open-ended inclusive meaning and means that additional elements/components/etc may be present in addition to the listed elements/components/etc; the terms “first”, “second” and “third” ”, etc. are used only as markers, not as restrictions on the number of objects.
