Foldable Display Support Assembly With Sliding Middle Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable electronic devices with multi-body linkage mechanisms cause stretching or squeezing of flexible display screens during unfolding and folding, leading to potential damage and reduced service life.
Innovation Solution
A foldable apparatus with a spindle assembly and two rotating components, where at least one rotating component includes a middle frame, rotating holder, and transmission structure, allowing the middle frame to slide parallel to the rotating holder, adjusting the length to match the flexible display screen's length in both unfolding and folding states, preventing stretching or squeezing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional multi-body linkage mechanisms are used to support the flexible display screen, then the foldable apparatus can achieve folding and unfolding motion, but the flexible display screen is stretched or squeezed during the process, affecting its service life
Solution Approach 1:
The patent applies the dynamics principle by making the supporting surface length variable through a transmission structure that converts rotational motion into linear motion. The middle frame slides relative to the rotating holder, dynamically adjusting the supporting surface length to match the flexible display screen length during folding and unfolding, thereby preventing stretching or squeezing while maintaining operational functionality.
2Adaptability or versatility
If the supporting surface length is fixed, then the structure is simple, but it cannot adapt to different lengths of flexible display screen in folding and unfolding states
Solution Approach 1:
The supporting surface length is made dynamic rather than fixed. The transmission structure includes a middle frame that can slide relative to the rotating holder, allowing the supporting surface length to vary and adapt to different configurations of the flexible display screen during folding and unfolding operations.
Solution Approach 2:
The transmission structure acts as an intermediary mechanism between the rotating holder and the middle frame. It converts the rotational motion of the rotating holder into linear sliding motion of the middle frame, enabling adaptive length adjustment without requiring complex direct linkage mechanisms.

AI summary
A foldable apparatus for supporting a flexible display screen includes a spindle assembly and two rotating components. At least one of the two rotating components is a first rotating component that includes a middle frame, a rotating holder, and a transmission structure. The rotating holder is rotatably connected to the spindle assembly. The middle frame is located at a side of the rotating holder away from the spindle assembly. The middle frame and the rotating holder is configured to slide in parallel. The transmission structure has one end connected to the spindle assembly and another end connected to the middle frame. The middle frame is configured to adhere to the flexible display screen. When the first rotating component rotates relative to the spindle assembly, the transmission structure moves relative to the rotating holder and drives the middle frame to slide in parallel relative to the rotating holder.
