Solution Overview
Problem
Existing foldable electronic devices face issues with bilateral synchronous rotation, leading to the flexible display panel being pressed or pulled, reducing the service life of the device.
Innovation Solution
A hinge mechanism with synchronized rotation mechanisms, including a fixed support, first and second rotation mechanisms, and a moving block, connected by transmission members and holding mechanisms, ensuring both sides of the hinge rotate at the same speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two rotation mechanisms are disposed opposite to each other in the hinge to enable folding and unfolding, then the electronic device can be folded or rolled to reduce size and improve portability, but the two rotation mechanisms cannot always rotate at the same speed resulting in the flexible display panel being pressed or pulled and reducing service life
Solution Approach 1:
A moving block is introduced as an intermediary component that connects both rotation mechanisms. The moving block includes a first extension portion connected to the first rotation mechanism and a second extension portion connected to the second rotation mechanism, acting as a mediator to synchronize the rotation of both mechanisms and prevent the flexible display panel from being pressed or pulled.
Solution Approach 2:
The transmission members are designed to be rotatably connected to the moving block, allowing dynamic adjustment of the rotation speed between the two rotation mechanisms. This dynamic connection enables the mechanisms to rotate at different speeds during different phases of folding/unfolding while maintaining synchronization overall, preventing stress on the display panel.
2Volume of moving object
If two rotation mechanisms are used to achieve folding effect, then the device can be folded to reduce size, but bilateral synchronous rotation cannot be achieved causing the flexible display panel to be pressed or pulled
Solution Approach 1:
The moving block serves as a mediator between the two rotation mechanisms, with extension portions that connect to both mechanisms. This intermediary structure ensures that both rotation mechanisms rotate synchronously by mechanically coupling them through the moving block, preventing the flexible display panel from being pressed or pulled during folding operations.
Solution Approach 2:
The hinge is segmented into two independent rotation mechanisms that can be controlled separately but are coupled through the moving block. Each rotation mechanism can be optimized for specific folding phases while the moving block ensures overall synchronous rotation, allowing the device to fold to reduced size while maintaining rotational stability.

AI summary
A hinge, a flexible display panel, and an electronic device are provided by the present disclosure. The electronic device includes a flexible display panel which includes a hinge. The hinge includes a first rotation mechanism, a second rotation mechanism, and a moving block. The first rotation mechanism and the second rotation mechanism are interlinked by the moving block, so that the first rotation mechanism and the second rotation mechanism always maintain the same rotation speed, thereby achieving an effect of bilateral synchronous movement in the electronic device.
