Battery Holder Beam Structure for Reliable Quick-Swap Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery installation methods in vehicles face challenges with reliability and quick replacement due to low middle strength in battery brackets, making it difficult to securely install and detach batteries, and limiting the versatility and compatibility of battery modules.
Innovation Solution
A bracket design with a pair of first beams and support beams that separate into subspaces, equipped with locking mechanisms, enhances strength and allows for compact and efficient battery arrangement, facilitating quick replacement and improved space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cuboid annular frame bracket is used to install a single battery, then the battery can be installed to the vehicle body, but the strength at the middle part of the bracket is low, making the installation reliability of the battery on the bracket insufficient
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, eliminating the weak middle section problem of the traditional annular frame and enhancing overall structural strength and reliability.
Solution Approach 2:
The bracket structure transitions from a two-dimensional annular frame to a three-dimensional distributed support system with multiple beams positioned at different locations (front, middle, rear subspaces). This spatial distribution adds dimensional complexity that significantly improves structural rigidity and load-bearing capacity.
2Ease of operation
If bolts are used to directly connect the battery to the vehicle body, then the connection is simple, but the battery is inconvenient to be installed and detached, and quick replacement is not facilitated
Solution Approach 1:
The locking mechanism incorporates movable locking blocks that can transition between locked and unlocked states through a lifting rod actuator. This dynamic design allows the battery to be securely fixed during operation but quickly released when replacement is needed, achieving both secure installation and rapid replacement without permanent bolt connections.
Solution Approach 2:
The locking mechanism is designed to be self-actuating through the lifting rod that automatically engages or disengages the locking blocks when moved vertically. This self-service mechanism eliminates the need for complex manual bolt operations, enabling quick replacement by simply lifting the rod to release the locking blocks.
3Volume of moving object
If a traditional bracket structure is used, then the structure is simple, but the space utilization is low and battery volume cannot be maximized
Solution Approach 1:
The bracket divides the battery installation space into multiple independent subspaces (first, second, third subspaces) using vertically distributed support beams. This segmentation allows for optimized battery arrangement and maximizes space utilization within the available volume, while the modular beam structure maintains relative simplicity in manufacturing and assembly.
