Integrated Battery Box Fixing Structure for Anti-Shake Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power battery packs face stability issues during mounting and transferring, particularly in high-frequency and high-intensity applications like electric vehicles, due to inadequate structural strength and the risk of damage from shaking and welding-related complications.
Innovation Solution
A fixing structure comprising a first connecting body, a second connecting body, and a transition body, integrally formed with the battery box, providing enhanced stability and resistance through multiple connecting holes and a through hole configuration, allowing for secure mounting and reduced risk of damage during high-intensity movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional mounting structures are used for battery packs, then the device complexity is reduced, but the stability and pulling-dragging resistance during high-frequency and high-intensity movement operations deteriorates
Solution Approach 1:
The patent merges the first connecting body, transition body, and second connecting body into an integral fixing structure that is directly formed on the battery box. This integration eliminates the need for separate mounting components while providing multiple connecting holes for stable attachment, thereby improving stability without increasing device complexity.
2Strength
If welding is used for mounting the battery pack, then the strength of the connection is improved, but the manufacturing precision and reliability deteriorate due to welding-related complications
Solution Approach 1:
The patent replaces welding with a mechanical connection system using multiple connecting holes that accommodate bolts or other fasteners. This mechanical substitution eliminates welding-related complications such as heat distortion and structural weakening, thereby improving manufacturing precision and reliability while maintaining connection strength.
3Reliability
If a simple mounting structure is used, then the ease of manufacture is improved, but the reliability during high-intensity movements deteriorates
Solution Approach 1:
The patent segments the fixing structure into multiple functional parts: a first connecting body for primary attachment, a transition body for structural reinforcement, and a second connecting body for additional mounting points. This segmentation allows each component to be optimized for its specific function, improving overall mounting reliability while maintaining ease of manufacture through modular design.
