Power Battery Pack Layout Around a Transmission Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power battery packs in all-terrain vehicles have an unreasonable structural design, leading to suboptimal layout and interference with other components like the transmission shaft, resulting in low integration level and structural strength.
Innovation Solution
A power battery pack with an avoidance portion at its bottom that cooperates with the transmission shaft, allowing the battery pack to be installed on the frame in a way that the transmission shaft can pass through, optimizing the vehicle's layout and enhancing structural integration and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power battery pack is installed on the frame without an avoidance portion, then the battery pack structure is simple, but the transmission shaft cannot pass through and interferes with the battery pack
Solution Approach 1:
An avoidance portion is extracted from the bottom of the power battery pack housing, creating a localized recessed region that allows the transmission shaft to pass through. This extracts the interfering portion from the solid battery pack structure, enabling the transmission shaft to traverse the battery pack area without collision while maintaining the overall integrity of the battery pack assembly.
2Power
If the power battery pack has a large volume to provide sufficient power, then the power capacity is improved, but the layout space on the vehicle is reduced and interferes with other components
Solution Approach 1:
The avoidance portion creates a vertical dimension change in the battery pack housing, recessing downward to allow the transmission shaft to pass through the battery pack's horizontal space. This dimensional approach allows the battery pack to maintain its full horizontal footprint for power capacity while accommodating the transmission shaft vertically, optimizing the three-dimensional layout without reducing power capacity.
3Adaptability or versatility
If the power battery pack is designed with reasonable layout to avoid interference, then the integration level is improved, but the structural design becomes more complex
Solution Approach 1:
The avoidance portion is a localized structural feature at the bottom of the battery pack housing, concentrating the design complexity to a specific local region rather than distributing it throughout the entire battery pack structure. This local quality approach allows the majority of the battery pack to maintain simple, standardized construction while only the avoidance portion requires specialized design to accommodate the transmission shaft.
