Busbar Support Shielding Pole Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack assembly methods fail to provide adequate protection for the pole assembly, which is prone to damage during assembly or use, and the supports for the busbar do not effectively safeguard the pole assembly.
Innovation Solution
A battery pack design featuring a busbar support with a main body portion for arranging the busbar and a protection portion connected to the main body, positioned on the lateral surface of the battery pack to shield the pole assembly, along with an assembly method that includes fixing the busbar support and engaging the pole assembly between the protection portion and the main body portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If supports are arranged on the lateral surface of the battery for busbar assembly positioning, then assembly positioning between busbar and pole assembly is ensured, but the pole assembly cannot be protected from collision and squeezing damage
Solution Approach 1:
The busbar support structure is designed to perform multiple functions: it provides assembly positioning for the busbar while simultaneously serving as a protective shield for the pole assembly. The support extends to cover the pole assembly, allowing one component to fulfill both positioning and protection roles, thereby resolving the contradiction between ensuring positioning precision and protecting the pole assembly.
Solution Approach 2:
The protective function for the pole assembly is merged with the busbar support structure. Instead of using separate supports for positioning and separate protective elements, the invention combines these functions into a single integrated support that both positions the busbar accurately and shields the pole assembly from damage during assembly and use.
2Reliability
If the busbar support is designed to protect the pole assembly, then the pole assembly is shielded from damage, but the assembly positioning function may be compromised
Solution Approach 1:
The busbar support is designed as a multi-functional component that simultaneously provides protective coverage for the pole assembly and maintains precise assembly positioning for the busbar. The support's geometry is configured to extend over the pole assembly while incorporating positioning features that ensure accurate busbar alignment, thus achieving both protection and positioning precision without compromise.
