Flexible Screen Telescopic Structure for Compact Large Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible electronic devices with large-sized screens have a large overall volume due to a folded structure.
Innovation Solution
A flexible screen telescopic structure with a middle frame support, sliding support, driving mechanism, and flexible screen, utilizing a transmission rope and guide members to enable compact expansion and contraction, allowing the flexible screen to be stretched or retracted smoothly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a folded structure is used to achieve a large-sized screen, then the screen area is increased, but the overall volume of the device becomes large
Solution Approach 1:
The patent employs a telescopic structure where the sliding support can move relative to the middle frame support, allowing the flexible screen to dynamically extend and retract. This dynamic mechanism enables the screen area to change while maintaining a compact overall volume when retracted, resolving the contradiction between large screen area and small device volume.
Solution Approach 2:
The patent utilizes the third dimension (depth/extension direction) to accommodate the large screen area. By allowing the sliding support to extend in the direction parallel to the first side surface, the screen can achieve a large display area without increasing the device's width or height, thus maintaining a compact overall volume.
2Reliability
If a flexible screen is made bendable and stretchable, then the durability and flexibility are improved, but the structural complexity increases
Solution Approach 1:
The patent divides the support structure into two separate components: a middle frame support and a sliding support. This segmentation allows the flexible screen to be stretched and bent without compromising the overall structural integrity, while keeping each component relatively simple in design, thus resolving the contradiction between improved durability and reduced structural complexity.

AI summary
The present disclosure discloses a flexible screen telescopic structure and an electronic device, and relates to the technical field of flexible screen stretching. The flexible screen telescopic structure comprises a middle frame support, a sliding support, a driving mechanism and a flexible screen. The sliding support is slidably connected to the middle frame support, and the flexible screen is connected to a first side surface of the middle frame support and bypasses an abutting edge of the sliding support. The driving mechanism comprises a driving member, a guide member and a transmission rope, wherein the guide member is rotatably connected to the middle frame support; the transmission rope is wound around the guide member and is connected to the driving member, and the transmission rope is connected to the sliding support of the connecting portion, with the connected part being a connecting portion; the driving member is used for driving the transmission rope to move around the guide member, and enables the connecting portion to drive the sliding support to move in a first direction, so that the flexible screen is pushed by the abutting edge, moves around the abutting edge and is gradually stretched on the first side surface. The flexible screen telescopic structure and electronic device have the characteristics of compact structure and small volume.
