Flexible Battery Module Structure for Foldable Display Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal equipment with rigid batteries limits the movement forms of flexible display modules, as the rigidity of the batteries restricts the folding, bending, and curling capabilities of the equipment.
Innovation Solution
A battery module is designed with a plurality of energy storage cells arranged along a first direction, connected by flexible connecting portions, and supported by flexible support housings and spacers, allowing for flexible bending and curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid battery is used in terminal equipment, then the battery provides stable structural support and reliable energy storage, but the rigidity of the battery limits the movement forms (folding, bending, curling) of the flexible display module
Solution Approach 1:
The battery is divided into multiple independent energy storage cells (first, second, third, and fourth cells) that can be independently positioned and supported. Each cell is accommodated by a corresponding support housing, allowing individual cells to move independently while maintaining overall battery functionality. This segmentation enables the battery to adapt to flexible display module movements without requiring the entire battery structure to be rigid or completely flexible.
Solution Approach 2:
The support housings are connected through connecting members with preset flexibility, creating a dynamic structure that can adapt its configuration based on movement requirements. The support spacers provide preset flexibility, allowing the support housings to adjust their positions relative to each other. This dynamic structure enables the battery to maintain stable energy storage while accommodating folding, bending, and curling movements of the flexible display module.
2Quantity of substance
If multiple energy storage cells are arranged along a direction to increase battery capacity, then the battery provides sufficient energy storage, but the increased number of cells and connecting components increases device complexity
Solution Approach 1:
Multiple energy storage cells are arranged in parallel along the first direction and connected through common support housings and connecting members. The support housings serve dual functions: providing structural support for individual cells and acting as connection points for the flexible connecting members. This merging of support and connection functions reduces the number of separate components needed, thereby reducing overall structural complexity while maintaining adequate battery capacity.

AI summary
A battery module, a flexible display apparatus, and a mobile terminal are described. A battery module includes energy storage cells disposed along a first direction, a flexible connecting portion connected between adjacent energy storage cells for transmitting electric energy, and support housings corresponding to the energy storage cells in a one-to-one correspondence, a support housing being provided with an accommodation cavity that fits an energy storage cell. The first side of the support housing is provided with an opening, a width of the support housing in the first direction is gradually decreased from the second side to the first side, the second side is opposite to the first side. The battery module further includes a support spacer with preset flexibility, where the support housings are disposed on one side of the support spacer along the first direction, and connecting members with preset flexibility connected between adjacent supporting housings.
