Vehicle Battery Support Frame With Removable Storage Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage units for motor vehicles lack a cost-effective and simple method for achieving a rigid connection to the vehicle body while allowing for easy replacement of storage modules without dismounting the entire support frame.
Innovation Solution
The energy storage unit incorporates a support frame with retaining elements on the vehicle body, allowing storage modules to be mounted and removed independently, with the support frame being non-destructively detachably connected to the body via retaining elements, such as cross members, which enhances rigidity and facilitates module replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire battery pack is dismounted to replace storage modules, then the connection rigidity can be ensured, but the replacement effort and time increase significantly
Solution Approach 1:
The battery pack is segmented into a support frame and multiple storage modules. The support frame remains mounted on the vehicle while individual storage modules can be independently removed and replaced. This segmentation allows module replacement without dismounting the entire battery pack, reducing replacement time and effort while maintaining connection rigidity through the permanent support frame attachment.
2Strength
If the support frame is permanently mounted to ensure rigidity, then accident performance improves, but module replacement becomes difficult
Solution Approach 1:
The system separates the mounting function (support frame permanently attached to vehicle body) from the storage function (removable storage modules). The support frame provides rigid permanent mounting to ensure accident performance, while storage modules are designed as independent replaceable units that can be easily swapped without affecting the support frame's permanent connection to the vehicle.
3Reliability
If cross members are used for mounting, then accident-related forces are better directed through the body shell, but the complexity of the mounting structure increases
Solution Approach 1:
The cross members serve multiple functions: they provide structural support for the vehicle body, act as mounting elements for the support frame, and serve as load-bearing components for directing accident-related forces through the body shell. This multi-functionality improves accident performance while avoiding the need for separate dedicated mounting structures, thereby controlling complexity.

AI summary
An energy storage unit for a motor vehicle has a support frame which can be non-destructively detachably mounted on a body of the motor vehicle and a plurality of storage modules for storing electrical energy which can be mounted on the support frame. The storage modules are configured as intrinsically sealed units which can be arranged on the support frame from bottom to top in the vertical direction of the vehicle and can be inserted into respective corresponding receiving openings in the support frame.
