Battery Fixing Bracket Using Side Clearance for Harness Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited space inside battery boxes poses a challenge for effectively fixing and stowing busbars and wiring harnesses, leading to reduced energy density and increased weight due to the use of harness ties that occupy internal space.
Innovation Solution
A fixing bracket with a fixing piece and buckle system that inserts into the clearance between the battery module and the box, using snap-fitted mechanisms and adjustable components to securely fix busbars and wiring harnesses without occupying additional space, thereby enhancing compactness and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional harness ties are used to fix busbars and wiring harnesses, then the busbars and wiring harnesses can be securely fixed, but the internal space of the box is occupied, reducing energy density
Solution Approach 1:
The fixing bracket utilizes the clearance dimension between the battery module and the box lateral face, transitioning from occupying internal storage space to utilizing the lateral clearance space. The fixing piece is inserted into the clearance along the length direction of the fixing piece, effectively using the available lateral dimension rather than consuming internal volume.
Solution Approach 2:
The fixing function is extracted from the internal space of the box and relocated to the clearance area between the battery module and the box. The fixing bracket is disposed in the clearance between the battery module and the box, separating the fixing function from the internal storage space and eliminating the space occupation problem.
2Volume of moving object
If the clearance between battery module and box is utilized for fixing, then space is saved and energy density increases, but the fixing stability must be ensured
Solution Approach 1:
The fixing bracket is divided into functional segments: a fixing piece for insertion and anchoring, and a buckle for securing the wiring harness. The fixing piece includes a first snap portion and a second snap portion that are snap-fitted to each other, creating multiple fixation points that ensure stability within the limited clearance space.
Solution Approach 2:
The snap portions utilize elastic deformation and curved geometry to achieve secure fixation. The snap-fitted mechanism allows the buckle to elastically engage with the fixing piece, providing reliable holding force within the constrained clearance dimension while maintaining fixing stability.

AI summary
A fixing bracket includes a fixing piece and a buckle. The fixing piece is configured to be inserted into a clearance between a battery module and a lateral face of a box along a length direction of the fixing piece, and one end of the fixing piece is connected to a bottom of the box. The buckle is connected to another end of the fixing piece, and includes a first snap portion and a second snap portion that are snap-fitted to each other. An accommodation channel configured to accommodate the wiring harness is formed between the first snap portion and the second snap portion.
