Traction Battery Mounting Bracket for Fast Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting high-voltage traction batteries on commercial vehicles are time-consuming due to the weight and complexity of the batteries, making the process inefficient on production lines.
Innovation Solution
A two-part holding device with a first holder fastened to the carrier frame and a second holder pre-assembled on the storage unit, allowing for quick assembly by sliding, inserting, or latching the second holder into the first holder, which includes features like sliding guides, latches, and clamping devices for secure positioning and stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pining methods are used to attach high-voltage traction batteries to the carrier frame, then the battery can be securely fastened, but the mounting process becomes time-consuming and complex
Solution Approach 1:
The holding device is divided into two separate holders: a first holder that is permanently mounted on the carrier frame, and a second holder that is temporarily attached to the battery. This segmentation allows the permanent mounting structure to be prepared in advance, while the temporary holder enables quick battery attachment and removal without complex pining operations.
Solution Approach 2:
The first holder is pre-mounted on the carrier frame during vehicle assembly, and the second holder is pre-assembled with the battery. This preliminary preparation eliminates the need for time-consuming on-site fastening operations, as the battery can be quickly attached by simply connecting the pre-prepared holders.
2Reliability
If high-voltage traction batteries are securely fastened using complex pining processes, then mounting reliability is improved, but the handling and assembly complexity increases
Solution Approach 1:
The fastening system is segmented into a permanent first holder on the frame and a removable second holder on the battery. This division simplifies the overall fastening process by separating the complex permanent mounting structure from the simple temporary attachment mechanism, reducing handling complexity while maintaining reliability.
Solution Approach 2:
The complex fastening operations are extracted from the battery attachment process itself and transferred to the permanent first holder mounted on the frame. The battery only needs to be attached to the simple second holder, which then connects to the already-secured first holder, thereby extracting complexity from the variable battery mounting step.
3Reliability
If conventional mounting methods are used for high-voltage traction batteries, then secure attachment is achieved, but production line efficiency decreases
Solution Approach 1:
The first holder is pre-installed on the carrier frame during vehicle manufacturing, and the second holder is pre-assembled with the battery. This preliminary preparation enables rapid battery installation on the production line, significantly improving productivity while maintaining secure attachment through the dual-holder system.
Solution Approach 2:
By segmenting the holding device into two separate holders with distinct functions, the system enables streamlined production line operations where the battery is quickly attached by connecting the pre-prepared second holder to the permanently mounted first holder, thereby improving assembly efficiency without compromising attachment security.

AI summary
The invention relates to a device, system, and method for mounting a storage unit for drive energy on a carrier frame of a vehicle. The invention further relates a vehicle having such a device.The device (100) for holding a storage unit (3) for drive energy, e.g. of a high-voltage traction battery of a storage unit (3), comprises a first holder (100a; 100b) for fastening the device to the carrier frame (2) and a second holder (200a; 200b) for fastening the device to the storage unit (3), the second holder (200a; 200b) being configured such that it may be pushed onto, inserted into and/or latched onto the first holder (100a; 100b) in order to pre-position the first and second holders (100a; 100b; 200a; 200b) with respect to one another. This enables rapid assembly of the storage unit (3) on a production line, since the first and second holders can each be preassembled separately from one another on the carrier frame and storage unit, respectively, and may be brought together quickly and securely during assembly on the production line to hold the storage unit by pushing on, inserting into, and/or latching in the second holder (200a; 200b) on the first holder (100a; 100b).
