EV Battery Support Frame With Detachable Bottom Plate Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to provide an energy storage unit for electric vehicles that effectively supports and protects battery modules, absorbs dynamic loads during driving, ensures leak-tightness, and facilitates easy maintenance and repair, while considering the weight and placement of battery modules in the vehicle.
Innovation Solution
The energy storage unit comprises leak-tight battery modules mounted on a detachable support structure with a bottom plate, featuring a support frame and load-distributing materials, and includes a design with air gaps and profiles for enhanced protection and accessibility, allowing for secure attachment to the vehicle's battery compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery modules are placed in the floor area of the vehicle to improve driving behavior, then the driving behavior is improved, but the support structure must bear considerable static and dynamic loads
Solution Approach 1:
The support structure is divided into a support frame and a bottom plate that can be detachably connected. This segmentation allows the support structure to be optimized for both load-bearing capacity and ease of maintenance, resolving the contradiction between improved driving behavior and structural strength requirements.
Solution Approach 2:
The bottom plate is designed to be detachably connectable to the support frame, allowing the support structure to dynamically adapt between a fixed state for load-bearing and a disassembled state for maintenance access. This dynamic design addresses both the strength requirement and the maintenance accessibility requirement.
2Reliability
If the support structure is designed to provide best possible protection for battery modules in the event of an accident, then the protection is improved, but the access to battery modules for maintenance and repair becomes difficult
Solution Approach 1:
The support structure is segmented into a support frame and a bottom plate that can be detachably connected. This allows the bottom plate to be removed for maintenance access while the support frame remains to provide structural protection, resolving the contradiction between protection and accessibility.
Solution Approach 2:
The bottom plate is extracted as a separate, detachable component from the support frame. This extraction allows maintenance personnel to remove the bottom plate for easy access to battery modules while the support frame continues to provide accident protection, addressing both protection and ease of repair requirements.
3Ease of repair
If the energy storage unit is designed with a detachable support structure for easy maintenance, then the ease of repair is improved, but the structural integrity and load-bearing capacity may be compromised
Solution Approach 1:
The support structure is segmented into a support frame and a bottom plate with detachable connection. The support frame maintains structural integrity for load-bearing, while the bottom plate can be detached for maintenance, resolving the contradiction between ease of repair and structural stability.
Solution Approach 2:
Different parts of the support structure have different qualities: the support frame is designed for structural integrity and load-bearing capacity, while the bottom plate is designed for ease of removal and maintenance access. This local differentiation resolves the contradiction between structural stability and ease of repair.
