Foldable Display Shaft-End Protection for Drop Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display terminals with flexible displays are prone to damage from falls, especially when in a folded state, affecting user experience.
Innovation Solution
A foldable assembly with rotating shafts, mechanical parts, and protective structures that extend beyond the display's surface to absorb impact before the display, and sliding connections to reduce pulling forces, enhancing anti-collision performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display is exposed outside in a folded state to improve accessibility, then ease of operation is improved, but the display becomes more vulnerable to damage from falls
Solution Approach 1:
The patent applies preliminary action by positioning the protective structure to extend beyond the display surface before any fall occurs. This proactive design ensures that the protective structure is already in place to intercept impact forces, preventing damage to the flexible display while maintaining its exposed position for accessibility.
Solution Approach 2:
The protective structure serves as an intermediary element between the flexible display and external impact forces. It absorbs and distributes collision forces, acting as a mediator that protects the vulnerable display from direct contact with harmful external factors during falls.
2Strength
If the protective structure is made higher than the display surface to improve collision resistance, then strength is improved, but the device complexity increases
Solution Approach 1:
The protective structure is merged with the existing foldable assembly components rather than being a separate attachment. This integration approach provides enhanced collision resistance while avoiding the need for additional independent structural elements, thereby limiting the increase in device complexity.
Solution Approach 2:
The protective structure serves multiple functions: it provides collision resistance, maintains the exposed position of the display, and integrates with the foldable mechanism. This multi-functionality reduces the need for separate components, balancing enhanced strength with controlled structural complexity.

AI summary
Embodiments of this application disclose a foldable assembly and a foldable display terminal. The foldable assembly is configured to bear a flexible display. The foldable assembly includes a rotating shaft; a first mechanical part and a second mechanical part, where the first mechanical part and the second mechanical part are rotatably connected by using the rotating shaft; and a first protective structure, where the first protective structure is connected to an end face that is of the rotating shaft and that extends out of a periphery of the flexible display. Therefore, the first protective structure is disposed, to protect the flexible display, and avoid a case in which the flexible display is damaged due to a fall of the foldable display terminal. A first surface of the flexible display is away from the rotating shaft, and the first protective structure is higher than or flush with the first surface of the flexible display, so that when the foldable display terminal falls, the first protective structure is in contact with a point of collision earlier than the flexible display, to enhance protection of the flexible display, and further improve anti-collision performance of the foldable display terminal.
