Vehicle Battery Mount Structure With Through Pipe And Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle battery mount structures face challenges in space utilization and fixing efficiency, especially when the inner space of the battery pack is small, leading to reduced energy density, increased battery module height, and inadequate connectivity between the upper and lower cases.
Innovation Solution
A vehicle battery mount structure that includes a through pipe, a fixing member, and a through bolt, where the through bolt passes through the through pipe and fixing member to securely fix the battery module to the vehicle body, reducing the number of parts and enhancing fixing force, with the through pipe and lower support member being integrally formed to maximize space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate member is applied to an interior of a battery case, then the battery module can be fixed to the vehicle body, but the number of parts increases requiring additional hardware and brackets
Solution Approach 1:
The lower support member integrates multiple functions: it serves as a structural support for the battery module, provides mounting points for fixing holes, and acts as a coupling element between the lower case and the vehicle body. This consolidation eliminates the need for separate brackets and reduces the number of hardware components required.
2Reliability
If a separate member is applied to an interior of a battery case, then the battery module can be fixed to the vehicle body, but additional parts including three or more kinds of hardware and three or more kinds of separate brackets are required
Solution Approach 1:
The lower support member is designed as a universal component that performs multiple functions: structural support, fixation mounting, and coupling. By making this single component multi-functional, the patent eliminates the need for multiple specialized parts such as separate brackets and various hardware components.
3Reliability
If a conventional battery mount structure is applied, then the battery module can be fixed, but the inner space of the battery pack is insufficient leading to low energy density
Solution Approach 1:
The fixing structure is segmented into integrated components (lower support member with fixing holes) that are directly formed as part of the battery case structure. This segmentation allows for optimized space utilization within the battery pack by eliminating the need for additional separate mounting components that would occupy valuable inner space.
4Reliability
If a mounting part is applied to an upper space of a battery module, then the battery module can be fixed, but the height of the battery module is increased lowering space utilization
Solution Approach 1:
Instead of adding mounting parts that extend vertically and increase battery module height, the fixing holes are integrated into the side surfaces of the lower support member. This dimensional repositioning allows fixation to occur laterally rather than vertically, maintaining a compact battery module height while achieving secure mounting to the vehicle body.

AI summary
A vehicle battery mount structure includes: a battery module fixed to a vehicle body; a through pipe disposed in the battery module; a fixing member configured to fix a lower case and an upper case of the battery module; and a through bolt configured to fix the battery module to a vehicle body bottom frame. The through bolt passes through the through pipe and the fixing member and is coupled to the fixing member.
