Bus Bar Housing Hinge with Stop Feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bus bar module accommodating part structures face difficulties in assembly with battery cell assemblies due to excessive deformation of hinges, leading to misalignment and challenges in mounting the bus bar module effectively.
Innovation Solution
The bus bar module accommodating part structure incorporates a projecting part on the first accommodating part's peripheral wall to restrict the movable range of the second accommodating part, preventing excessive deformation and ensuring proper alignment during assembly by using a hinge to connect the parts and an electric wire wiring part that acts as an abutting part to further restrict movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hinges are used to connect accommodating parts to allow movement and adjustment, then adaptability to battery cell assemblies with accumulated tolerance is improved, but excessive deformation of the accommodating parts occurs making assembly difficult
Solution Approach 1:
The hinge mechanism enables dynamic adjustment of the accommodating parts, allowing them to move and adapt to variations in battery cell assembly dimensions. This dynamic capability permits the bus bar module to accommodate tolerance accumulation while maintaining proper alignment through controlled movement rather than rigid fixed positioning.
Solution Approach 2:
The hinge mechanism changes the positional parameters of the accommodating parts relative to each other, enabling adjustment of gaps and angles to compensate for accumulated tolerance in the battery cell assembly. This parameter adjustment maintains alignment precision despite variations in the underlying battery structure.
2Ease of operation
If accommodating parts are made movable through hinges to accommodate tolerance, then ease of assembly is improved, but excessive deformation occurs restricting proper mounting
Solution Approach 1:
The hinge provides controlled dynamic movement that facilitates easy assembly by allowing the accommodating parts to self-adjust during installation. Simultaneously, the hinge's mechanical structure provides inherent stability limits that prevent excessive deformation, ensuring reliable and stable final assembly.
3Adaptability or versatility
If hinges connect accommodating parts with unlimited movable range, then adaptability to different configurations is improved, but excessive deformation makes bus bar module assembly difficult
Solution Approach 1:
The hinge mechanism provides dynamic adaptability through controlled movement, allowing the accommodating parts to adjust to different configurations and tolerance variations. The mechanical hinge structure inherently limits the range of motion, preventing excessive deformation while maintaining sufficient adaptability for proper alignment and assembly.

AI summary
A synthetic resin plate (1) includes a plurality of accommodating parts (2) which accommodate at least one of bus bars, terminals, and electric wires which are connected to the terminal, hinges (7) which make first accommodating parts and second accommodating parts of the accommodating parts (2) connected and relatively movable, and projecting parts which are provided on the top surfaces of peripheral wall parts of the first accommodating parts, and which abut against parts of the second accommodating parts to restrict the movable ranges in the movable directions of the second accommodating parts relative to the first accommodating parts.
