A battery assembly mounting structure featuring a swappable assembly with a mounting bushing, fastening bolt, and elastic components that allow the bolt to maintain assembly even when detached, facilitate easy replacement, and guide correct fastening angles to prevent errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery assembly is detachably mounted to the vehicle body using a fastening bolt, then the replaceability and charging efficiency are improved, but the fastening bolt requires separate handling and cannot maintain the assembled state when detached
Solution Approach 1:
The fastening bolt is integrated with the battery assembly through the swappable assembly, merging the fastening function with the battery assembly itself. This allows the fastening bolt to remain attached to the battery assembly during detachment, eliminating the need for separate handling and maintaining the assembled state when reattached.
Solution Approach 2:
The swappable assembly incorporates elastic components that allow the fastening bolt to dynamically adjust its position and maintain connection with the battery assembly. The elastic support enables the bolt to flex and retain attachment even when the battery assembly is separated from the vehicle body.
2Reliability
If a rigid mounting structure is used to securely fasten the battery assembly, then the mounting reliability is improved, but the assembly tolerance cannot be easily covered and erroneous fastening may occur
Solution Approach 1:
The mounting bushing cross-sectional shape is changed from a conventional form to an evenly formed circular cross-section in up and down directions. This geometric parameter change allows the swappable assembly to accommodate assembly tolerances while maintaining reliable fastening through the elastic components.
Solution Approach 2:
The swappable assembly acts as an intermediary between the rigid fastening bolt and the battery assembly mounting points. This intermediate structure absorbs assembly tolerances and guides the fastening bolt to the correct position, preventing erroneous fastening while maintaining secure attachment.
3Stability of the object's composition
If the fastening bolt is securely fixed to the battery assembly, then the assembled state is maintained, but the replacement of damaged fastening bolts becomes difficult
Solution Approach 1:
The fastening system is segmented into the fastening bolt, the swappable assembly, and the mounting bushing. This segmentation allows the fastening bolt to be easily replaced by simply detaching it from the swappable assembly, while the swappable assembly itself remains fixed to the battery assembly, maintaining the assembled state.
Solution Approach 2:
The fastening bolt is extracted as a separate, independently replaceable component from the swappable assembly. This extraction allows damaged fastening bolts to be easily removed and replaced without affecting the swappable assembly or the overall battery assembly mounting structure.
4Ease of repair
If the mounting structure is designed for easy replacement, then the repairability is improved, but the structure may lack sufficient stability when mounted
Solution Approach 1:
The swappable assembly uses elastic components that provide dynamic stability during normal operation while allowing easy replacement when needed. The elastic support maintains secure mounting through flexible connection, but the modular design enables quick removal and replacement of the entire swappable assembly if damaged.
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 reusable fastening bolts without separate handling, secures assembly and disassembly workability, and allows easy replacement of damaged components, enhancing the overall assembly process efficiency and reliability.
Implementation Method 1
a guide spring elastically supporting the sleeve with respect to the second fixing guide
Implementation Method 2
movement in the up and down directions of the swappable assembly with respect to the mounting bushing can be constrained by the elasticity of the first fixing guide

AI summary
A battery assembly mounting structure for a vehicle includes: a mounting bushing provided in a battery assembly to internally form a communication space in up and down directions; a fastening bolt installed to penetrate the space formed by the mounting bushing in the up and down directions; and a swappable assembly. The swappable assembly is elastically coupled to the mounting bushing and elastically supports the mounting bushing and the fastening bolt between the mounting bushing and the fastening bolt while elastically allowing the fastening bolt to move in a lengthwise direction.
