Tri-Fold Screen Hinge Layout for Enclosed G-Shaped Folding

The patent transitions from a symmetric S-shaped cross-section to an asymmetric G-shaped cross-section. The G-shape features an open end that allows the flexible screen to be fully enclosed and protected when folded, while the asymmetric structure enables better spatial arrangement of components. This asymmetric design resolves the contradiction by providing both foldability and complete screen protection.

The patent implements a nested structure where the flexible screen is fully contained within the G-shaped folded structure. The screen passes through the folding modules and is enclosed by the layered panel bodies, creating a protective nesting effect. This nesting principle ensures the screen is protected from external impacts while maintaining the device's compact folded form.

The folding modules serve multiple functions simultaneously: they enable the folding mechanism, provide structural support, guide the flexible screen through the folding process, and create the protective G-shaped enclosure. This multi-functionality reduces the need for additional separate components, thereby managing structural complexity while achieving complete screen protection.

The patent merges the folding mechanism with the protective enclosure structure. The same folding modules that enable the device to fold also form the G-shaped structure that encloses and protects the screen. By combining these functions into a single integrated structure, the patent avoids adding separate protective components, thus managing complexity while improving reliability.
