Battery Assembly Mounting Bushing With Retained Floating Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery assembly mounting structures face challenges in maintaining the assembled state during repeated attachment and detachment, prone to erroneous fastening, and require separate handling of fastening bolts for replacement.
Innovation Solution
A vehicle battery assembly mounting structure featuring a mounting bushing with a vertical space for a fastening bolt, guided by a sleeve assembly that elastically supports the bolt, allowing it to move and absorb assembly tolerance, preventing separation and facilitating easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fastening bolt is completely separated from the battery assembly during detachment, then the battery assembly can be easily removed from the vehicle body, but the fastening bolt requires separate handling and preparation for each attachment operation
Solution Approach 1:
The patent combines the fastening bolt with the battery assembly by providing a retaining structure that holds the bolt on the battery assembly during detachment. This merging ensures the bolt remains associated with the battery assembly, eliminating the need for separate handling and preparation during subsequent attachment operations.
Solution Approach 2:
The retaining structure is pre-configured on the battery assembly to hold the fastening bolt in place. This preliminary arrangement ensures that when the battery assembly is detached, the bolt is already positioned and ready for reuse, eliminating the need for separate preparation steps before reattachment.
2Stability of the object's composition
If the fastening bolt is rigidly fixed to the battery assembly, then the bolt maintains a stable assembled state, but the structure cannot absorb assembly tolerance and may cause erroneous fastening
Solution Approach 1:
The patent employs a dynamic retaining structure that allows the fastening bolt to move relative to the battery assembly within controlled limits. This dynamic arrangement enables the system to absorb assembly tolerances and misalignments while maintaining stable assembly through the bolt's guided movement capability.
Solution Approach 2:
The retaining structure allows for parameter changes in the position and orientation of the fastening bolt relative to the battery assembly. This flexibility enables the system to adapt to variations in assembly tolerance while maintaining proper fastening, preventing erroneous fastening through controlled parameter adjustment.
3Stability of the object's composition
If the fastening bolt is held firmly in the mounting bushing, then the bolt maintains assembled state during detachment, but the bolt cannot be easily replaced when damaged
Solution Approach 1:
The patent segments the fastening system into separable components: the fastening bolt, the mounting bushing, and the retaining structure. This segmentation allows the bolt to be held firmly during normal operations while enabling easy separation and replacement when damaged, as each component can be independently accessed and replaced.
Solution Approach 2:
The retaining structure acts as an intermediary between the fastening bolt and the battery assembly. It provides stable retention during detachment while allowing controlled release for replacement, mediating between the need for firm holding and easy replacement through its designed release mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures stable assembly and disassembly of the battery assembly without separate fastening bolt preparation, prevents erroneous fastening, and allows easy replacement of damaged bolts, enhancing the assembly process efficiency.
Implementation Method 1
a guide spring configured to elastically support a space between the fixing guide and the sleeve
Implementation Method 2
The sleeve may include a plurality of holding protrusions configured to elastically press and support an outer circumferential surface of the fastening bolt
Implementation Method 3
The fixing guide may be elastically deformed to be detachably mounted in the mounting bushing

AI summary
A vehicle battery assembly mounting structure includes: a mounting bushing provided in a battery assembly to form a space, the space allowing movement in a vertical direction; a fastening bolt disposed to vertically penetrate the space formed by the mounting bushing; and a sleeve assembly. The sleeve assembly is configured to guide the fastening bolt, to elastically prevent the fastening bolt from being separated from the mounting bushing and to elastically support the fastening bolt with respect to the mounting bushing to allow the fastening bolt to move in the mounting bushing.
