AI Technical Summary
In the prior art, the stretching or squeezing of the flexible screen during the unfolding and folding process of the folding device affects its service life.
Design a folding device, including a main shaft assembly and a rotating component. At least one of the rotating components is a first rotating component, which includes a middle frame, a rotating support, and a transmission structure. The transmission structure connects the main shaft assembly and the middle frame. The middle frame is driven to slide parallel to the rotating support through the transmission structure, thereby adjusting the length of the first rotating component to match the length changes of the flexible screen and avoid stretching or compression.
To ensure that the flexible screen maintains a constant length in both flat and folded states, damage to the flexible screen can be avoided, and its service life can be extended.
