Battery Bracket Structure for Quick-Replace Pack Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery installation methods for vehicles, either direct or using a bracket, face challenges in quick replacement and reliability due to inadequate structural strength, especially in the middle length direction, which affects the installation and maintenance of batteries.
Innovation Solution
A bracket design with a pair of first beams and support beams that separate the space into subspaces, enhanced by a locking mechanism and a U-shaped support beam structure, allowing for improved strength, compactness, and easy maintenance, facilitating quick battery replacement and increased energy density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cuboid annular frame bracket is used to install a single battery, then the battery installation is simplified, but the strength at the middle part is low and installation reliability cannot be guaranteed
Solution Approach 1:
The bracket is divided into multiple independent support beams (first support beam, second support beam, third support beam) that are distributed along the length direction. Each support beam independently supports batteries in different subspaces, avoiding the weak middle part problem of a single annular frame while maintaining structural simplicity.
2Reliability
If support beams are added to separate space into subspaces, then the strength and reliability are improved, but the bracket structure becomes more complex
Solution Approach 1:
Each support beam serves multiple functions: it provides structural strength, creates subspace boundaries, offers mounting positions for locking mechanisms, and supports multiple batteries. This multi-functionality reduces the need for additional specialized components, thereby improving reliability without proportionally increasing complexity.
3Area of stationary object
If the bracket structure is made compact with shared support beams, then space utilization rate increases, but the manufacturing complexity increases
Solution Approach 1:
The bracket is segmented into standardized support beams that can be manufactured independently and then assembled. This modular approach allows for compact arrangement with shared beams creating efficient subspace utilization while maintaining ease of manufacture through standardized components.
4Reliability
If a locking mechanism is added to secure batteries, then the installation reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The locking mechanism is designed to automatically lock the battery box body to the support beam when the battery is placed in position, without requiring additional manual intervention or complex control systems. The first locking mechanism engages with the box body automatically, providing reliable fixation while keeping the mechanism simple and cost-effective.
