Battery Module Mounting Arrangement for Tolerance Gap Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting systems for battery modules in electrically propelled vehicles require complex and expensive fastening arrangements or time-consuming methods due to shifting tolerances between the battery modules and the housing, necessitating space for easy sliding, which complicates secure fixation.
Innovation Solution
A mounting arrangement comprising a fastening element, mounting element, and compensating element that allows for adjustable engagement and compensation of gaps from the outer side of the housing, enabling secure fixation without welding and preventing rotation, with optional features like conical portions and engagement mechanisms for enhanced stability and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets or complex fastening systems are used to address shifting tolerances, then the battery module can be securely fixedated, but the device complexity and manufacturing cost increase
Solution Approach 1:
The mounting arrangement is divided into separate functional elements: a mounting element fixed to the housing, a compensating element that absorbs dimensional variations, and a fastening element for securing. This segmentation allows each component to perform its specific function independently, simplifying the overall system while maintaining secure fixation capability
Solution Approach 2:
The compensating element acts as an intermediary between the mounting element and the battery module, absorbing dimensional variations and tolerance shifts. This mediator component prevents the need for complex fastening systems by decoupling the mounting structure from the battery module, allowing simple fastening while maintaining reliability
2Ease of operation
If space is required around the battery module for easy sliding, then the mounting operation is simpler, but the available fixation space and structural stability are reduced
Solution Approach 1:
The mounting element and compensating element are pre-assembled and fixed to the housing before the battery module is installed. This preliminary action creates a ready-to-receive mounting structure that guides the battery module into position, eliminating the need for large clearance spaces while maintaining ease of mounting operation
Solution Approach 2:
The compensating element serves as a mediator that allows the battery module to be positioned correctly without requiring excessive clearance space. It absorbs the dimensional variations that would otherwise require large gaps, enabling compact design while maintaining easy mounting operation
3Reliability
If conventional fastening systems are used, then the battery module can be fixedated, but the mounting time and operational complexity increase
Solution Approach 1:
By segmenting the mounting system into pre-assembled components (mounting element + compensating element), the system enables rapid installation. The segmented design allows the battery module to be mounted quickly using simple fastening, reducing mounting time while maintaining fixation security through the dedicated fastening element

AI summary
A mounting arrangement for mounting a battery module to a housing of a mounting structure, the mounting arrangement comprises a fastening element adapted to engage the battery module from a first side of the housing facing away from the battery module, a mounting element adapted to be fixed relative to the housing and arranged on a second side of the housing facing the battery module, and a compensating element mounted to the mounting element.
