Movable Output End Protection Support for Battery Pole Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery packs, the inaccurate positioning between the output pole and the protection support results in dimensional deviations, leading to increased contact resistance, heat generation, and safety risks due to poor fitting.
Innovation Solution
The implementation of a battery pack design featuring a box body with two movably arranged output end protection supports, allowing for precise alignment and connection of the output pole, ensuring accurate fitting and reduced contact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the output pole and protection support are rigidly fixed with precise positioning, then the contact resistance is reduced and fitting is improved, but the assembly complexity and positioning difficulty increase
Solution Approach 1:
The protection support is designed with movable capability relative to the box body through guide slots and sliding blocks, allowing dynamic adjustment during assembly. This enables the support to adapt its position to accommodate dimensional variations of the output pole while maintaining good contact, thus reducing contact resistance without requiring complex rigid positioning structures.
2Device complexity
If the protection support position is fixed on the box body, then the structure is simple, but the dimensional deviation causes poor fitting and increased contact resistance
Solution Approach 1:
The protection support can move along guide slots on the box body, transforming a fixed rigid structure into a dynamically adjustable one. This allows the support to compensate for manufacturing tolerances and dimensional deviations of the output pole, achieving good fitting accuracy without increasing overall structural complexity.
Solution Approach 2:
The position of the protection support is changed from a fixed parameter to a variable parameter that can be adjusted during assembly. By allowing the support to move within a certain range defined by the guide slots, the system can adapt to variations in output pole dimensions and achieve optimal contact.
3Manufacturing precision
If the output pole and protection support are allowed to move relative to each other, then the fitting accuracy is improved, but the structural stability may be compromised
Solution Approach 1:
The system employs guided movement through slots and sliding blocks that constrain the motion to specific trajectories. This controlled dynamics allows adjustment for fitting accuracy while the guide structures themselves provide stability, preventing uncontrolled movement that would compromise structural integrity.
Solution Approach 2:
The guide slots and sliding blocks act as intermediary elements between the movable protection support and the fixed box body. These intermediaries enable controlled relative movement for positioning accuracy while maintaining structural stability through the constrained motion paths they provide.
