Battery Pack Mount Structure Preventing Case Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power requirements of electronic devices lead to larger battery packs that occupy significant space, causing physical strain and potential deformation of neighboring structures within the device, especially when fully charged.
Innovation Solution
The electronic device incorporates a battery pack mount structure with seat protrusions and recesses that allow the battery pack to be self-supported, preventing pressure on the backside of the mount portion and reducing the likelihood of deformation, while maintaining a secure and stable electrical connection.

Engineering Contradiction Analysis
1Power
If the battery pack capacity is increased to meet higher power requirements, then the power supply capability is improved, but the physical size of the battery pack increases and occupies more space within the electronic device
Solution Approach 1:
The battery pack is divided into multiple battery cells (first battery cell, second battery cell, etc.) that can be arranged in series to achieve the desired voltage and power output. This segmentation allows the power requirement to be met through configuration rather than simply increasing the size of a single battery, thereby managing the volume occupation more efficiently within the electronic device.
2Stability of the object's composition
If the battery pack is securely mounted within the electronic device, then the stability and electrical connection are improved, but the neighboring structures may be deformed or subjected to excessive forces
Solution Approach 1:
A mounting structure comprising a mount body and a support plate is introduced as an intermediary between the battery pack and the case frame. The mount body receives the battery pack while the support plate extends to contact the battery pack, distributing the forces and providing stable mounting without directly transmitting excessive forces to the case frame, thereby preventing deformation while maintaining stability.
Solution Approach 2:
The mounting structure is designed with specific geometric parameters and material properties that allow it to flexibly adapt to the battery pack while maintaining secure contact. By optimizing parameters such as the shape of the support plate, the position of mounting holes, and the thickness of structural elements, the system achieves stable mounting with reduced stress concentration on the case frame.

AI summary
An electronic device comprises a battery pack and a case frame. The case frame has an opening forming a battery pack mount portion in which the battery pack is mounted. The battery pack comprises a battery cell, and first and second support bodies supporting the battery cell on opposing ends of the battery cell. When the battery pack is mounted, the first and second support bodies are supported by the battery pack mount portion.
