Sliding-Groove Hinge Structure for Flexible Screen Folding Stress

The patent introduces an intermediary mechanism consisting of a support plate, rotating shaft, and buffering component that mediates between the folding action and the flexible display screen. This intermediary structure absorbs and distributes the stress during folding, preventing direct stress concentration on the screen. The buffering component specifically acts as a mediator to cushion the mechanical stress, thereby protecting the screen while enabling folding functionality.

The patent implements beforehand cushioning by incorporating a buffering component (such as a damping element or elastic component) in advance within the hinge structure. This buffering component is positioned to absorb and mitigate stress before it reaches the flexible display screen during the folding process. The cushioning effect is built into the structure beforehand, ensuring protection is active during folding operations.

The patent applies segmentation by dividing the hinge structure into multiple functional components: a support plate, a rotating shaft, and a buffering component. This segmentation allows each component to perform a specific function - the support plate provides structural basis, the rotating shaft enables rotation, and the buffering component reduces stress. By segmenting the structure, the patent achieves both functionality and stress distribution without excessive complexity.

The buffering component serves as an intermediary element between the rotating shaft and the flexible display screen. It mediates the stress transmission by absorbing and distributing forces, preventing stress concentration on the screen. This intermediary component adds minimal complexity while effectively eliminating the harmful stress concentration effect.
