Foldable Display Support Module With Synchronous Equal-Angle Folding

The supporting module is divided into multiple movable plates (first movable plate, second movable plate) that can independently fold relative to the fixed plate. Each movable plate has its own transmission assembly, allowing the display screen to be segmented into multiple folding sections rather than a single wedge-shaped fold, thereby reducing the folded thickness while maintaining structural simplicity

The patent introduces dynamic control mechanisms (transmission assemblies with tooth arms, synchronous gear sets, and torsion assemblies) that enable the movable plates to adjust their folding angles dynamically. The synchronous gear sets ensure both movable plates fold at the same angle simultaneously, while the torsion assemblies provide elastic forces to maintain uniform folding angles, transforming the static wedge-shaped fold into a dynamic controlled folding process that reduces creases and thickness

The torsion assemblies act as feedback mechanisms that provide elastic restoring forces to the movable plates. As the movable plates fold, the torsion assemblies deform and generate elastic forces that automatically adjust the folding angles to maintain uniformity. This feedback control ensures both movable plates maintain the same folding angle throughout the folding process, preventing crease formation and maintaining display quality without requiring complex control systems

The synchronous gear sets and torsion assemblies create a dynamic control system that continuously adjusts the folding angles during the folding process. The gear sets transmit motion synchronously while the torsion assemblies provide real-time force adjustment, ensuring the movable plates maintain equal angles with the fixed plate throughout folding. This dynamic adjustment prevents the display screen from forming creases by maintaining uniform stress distribution
