Battery Case Mounting Channel for Space-Saving Internal Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structures for battery cases in large electrical devices, such as commercial vehicles, occupy excessive space and hinder efficient space utilization due to the need for external mounting structures, which limits flexibility and increases the overall size of the battery case.
Innovation Solution
A battery case design featuring a frame with an integrated mounting channel and a connecting assembly that includes a connecting main body and fixing members, allowing for internal mounting points, thus eliminating the need for external mounting structures and enabling flexible adjustment of the mounting position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting structure is extended outward at the frame of the battery case, then the connection and fixation between the battery case and the electrical device is achieved, but the space occupation during the mounting is increased and the space utilization rate is reduced
Solution Approach 1:
The connecting main body is inserted into the mounting channel formed inside the frame, with the first fixing member arranged on the connecting main body. This nested configuration allows the mounting structure to be contained within the frame's internal space rather than extending outward, reducing the battery case's overall volume while maintaining connection functionality.
Solution Approach 2:
The mounting channel is formed inside the frame along the thickness direction, allowing the connecting main body to be inserted from the outside through the frame. This dimensional approach enables the mounting points to be located on the frame's outer surface while the connecting structure resides within the frame's internal volume, effectively utilizing three-dimensional space.
2Reliability
If mounting points are located outside the battery case, then the connection between the battery case and external structure is achieved, but the mounting flexibility and position adjustment capability are reduced
Solution Approach 1:
The position of the connecting hole on the frame can be adjusted, and the connecting main body can be inserted at different positions along the mounting channel. This dynamic configuration allows the battery case to be mounted at various positions and orientations, enhancing mounting flexibility while maintaining stable fixation through the connecting assembly.
3Reliability
If an external mounting structure is provided, then the battery case can be fixed to the electrical device, but the overall structural complexity is increased
Solution Approach 1:
The mounting channel is formed inside the frame by utilizing the inner cavity of at least one side plate, integrating the mounting structure into the frame itself rather than adding separate external components. The connecting main body and first fixing member form a unified connecting assembly that simplifies the overall structure while maintaining mounting capability.
