Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding display devices suffer from defective rotating shafts due to direct impact forces when they fall, affecting the bending and display effects.
Innovation Solution
A folding display device design featuring rotatably connected middle frames with bending members, including a rotating shaft and supporting plates, and a deadlocking structure with elastic members and sliding blocks that lock and unlock in perpendicular directions to distribute and absorb impact forces, preventing damage to the bending members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the folding display device uses a rotating shaft to connect middle frames, then the device can achieve rotatable bending function, but the rotating shaft is easily defective when impact force directly acts on it
Solution Approach 1:
The patent introduces a deadlocking structure as an intermediary between the middle frames and the rotating shaft. This deadlocking structure includes deadlocking components that can lock and unlock to control the transmission of force, protecting the rotating shaft from direct impact forces while maintaining the rotatable bending function during normal operation
Solution Approach 2:
The deadlocking structure provides beforehand protection by locking the middle frames together before impact forces can reach the rotating shaft. The elastic members in the deadlocking structure absorb and cushion the impact forces, preventing them from directly acting on the rotating shaft and causing defects
2Reliability
If the deadlocking structure locks the middle frames, then the impact force is protected from the rotating shaft, but the folding display device cannot be folded
Solution Approach 1:
The deadlocking structure employs dynamic locking and unlocking capabilities through elastic members and sliding blocks. The structure can transition between locked state (providing impact protection) and unlocked state (allowing folding operation), adapting its function based on operational requirements. The elastic members enable the locking components to move and disengage when folding forces are applied
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 deadlocking structure effectively reduces the likelihood of bending member defects by locking during impact and unlocking for free folding, ensuring the display device's structural integrity and functionality.
Implementation Method 1
a first elastic member disposed in the first accommodating cavity and fixedly connected to the first housing, wherein a deformation direction of the first elastic member is along the first direction; and a second elastic member disposed in the second accommodating cavity and fixedly connected to the second housing, wherein a deformation direction of the second elastic member is along the second direction
Implementation Method 2
a first sliding block disposed in the first accommodating cavity and fixedly connected to the first elastic member; and a second sliding block disposed in the second receiving cavity and fixedly connected to the second elastic member

AI summary
A folding display device and electronic device are provided. The folding display device includes a first middle frame, a second middle frame, two bending members, a flexible display panel, and a first deadlocking structure. The first deadlocking structure includes a first deadlocking component fixedly connected to the first middle frame and a second deadlocking component fixedly connected to the second middle frame. When the folding display device receives a first force, the two deadlocking components are locked and connected to reduce probability of defects in the bending members. When the folding display device receives a second, the two deadlocking components are unlocked to realize free folding.
