Foldable Housing Hinge Structure to Reduce Flexible Display Squeezing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inward foldable screen electronic devices suffer from poor reliability and short service life of flexible displays due to excessive squeezing during folding, which can damage the bending portion of the flexible display.
Innovation Solution
A folding mechanism with a housing apparatus that includes a middle housing, first and second fixing brackets, swing arms, and support plates that form a display accommodating space through automatic avoidance, reducing the squeezing force and ensuring stable folding actions to protect the flexible display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the housing apparatus folds the flexible display inward, then the device achieves a compact form factor, but the flexible display suffers from excessive squeezing force that damages the bending portion
Solution Approach 1:
The patent introduces a folding mechanism comprising swing arms, support plates, and brackets as intermediary components between the housing and flexible display. These components create display accommodating space that guides and cushions the folding motion, preventing direct contact between the housing and bending portion of the flexible display, thereby reducing squeezing force while enabling compact folding
2Device complexity
If the folding mechanism directly folds the flexible display, then the structure is simple, but the reliability of the flexible display decreases due to damage risk
Solution Approach 1:
The patent segments the folding mechanism into multiple functional components: swing arms for motion control, support plates for structural support, and brackets for connection. This segmentation allows each component to perform its specific function in protecting the flexible display during folding, improving reliability while maintaining reasonable structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The folding mechanism enhances the reliability and extends the service life of flexible displays by minimizing damage from excessive squeezing, while allowing for easy assembly and compact design of the electronic device.
Implementation Method 1
One end of the first swing arm is slidably connected to the first fixing bracket, and the other end of the first swing arm is rotatably connected to the middle housing
Implementation Method 2
One end of the first swing arm is slidably connected to the first fixing bracket, and the other end of the first swing arm is rotatably connected to the middle housing
Implementation Method 3
the first support plate and the second support plate form display accommodating space through automatic avoidance for accommodating a flexible display

AI summary
This application discloses a folding mechanism and an electronic device. The folding mechanism is applied to a housing apparatus of an electronic device, and is configured to connect two housings of the housing apparatus. The folding mechanism can form display accommodating space through automatic avoidance in a folding process, and a flexible display is accommodated in the display accommodating space, so that a folding action performed by the housing apparatus on the flexible display is stable, and a squeezing force is small. This helps reduce a risk that the flexible display is damaged due to excessive squeezing of the folding mechanism, and makes the flexible display more reliable.
