Traction Battery Mounting Holders With Slide-In Pre-Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting high-voltage traction batteries on vehicle frames are time-consuming due to the heavy weight and complex bolting process, necessitating an improved assembly technique for drive energy storage devices.
Innovation Solution
A two-part holding device comprising a first and second holder, where the second holder is designed to be slid onto, inserted into, or snapped into the first holder for quick attachment, with features like sliding guides, snap-fit connections, and clamping devices to secure the holders in position, allowing pre-assembly and easy installation on a conveyor belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bolting methods are used to mount high-voltage traction batteries on vehicle frames, then secure attachment is achieved, but assembly time increases significantly due to the heavy weight and complex bolting process
Solution Approach 1:
The holding device is divided into two separate holders: a first holder attached to the vehicle frame and a second holder attached to the storage device. This segmentation allows independent pre-assembly of each holder, eliminating the need for complex on-site bolting operations and significantly reducing assembly time while maintaining secure attachment through the combined holding structure.
Solution Approach 2:
Both holders are designed to be pre-assembled independently before final installation. The first holder can be pre-mounted on the vehicle frame, and the second holder can be pre-mounted on the storage device. This preliminary action eliminates the need for complex bolting operations during final assembly, reducing assembly time while ensuring secure attachment.
2Stability of the object's composition
If heavy high-voltage traction batteries are mounted using traditional bracket methods, then stable mounting is achieved, but handling during assembly and disassembly becomes difficult and time-consuming
Solution Approach 1:
By dividing the holding device into two separate holders that attach to different components (vehicle frame and storage device), the system enables independent handling of each holder. This segmentation makes assembly and disassembly operations easier while maintaining mounting stability through the combined holding structure.
Solution Approach 2:
The two holders act as intermediary components that simplify handling. The first holder serves as an intermediary between the vehicle frame and the storage device, while the second holder serves as an intermediary between the storage device and the first holder. These intermediaries make the heavy storage device easier to handle during assembly and disassembly while ensuring stable mounting.
3Reliability
If complex bolting processes are used for battery assembly, then secure attachment is ensured, but productivity on the assembly line decreases
Solution Approach 1:
The holding device is segmented into two independently pre-assemblable holders, eliminating the need for complex bolting processes on the assembly line. This segmentation allows for rapid attachment while ensuring secure connection, thereby significantly improving assembly line productivity without compromising attachment security.
Solution Approach 2:
Both holders are designed for preliminary assembly independent of each other, allowing preparation work to be done before the assembly line operation. This preliminary action eliminates time-consuming bolting processes during line assembly, improving productivity while maintaining secure attachment through the finalized holder design.

AI summary
The invention relates to a device, a system and a method for mounting a storage means for drive energy on a support frame of a vehicle and to a vehicle comprising such a device. The device (100) for mounting a storage means (3) for drive energy, for example a high-voltage traction battery of a storage means (3), comprises a first mounting means (100a; 100b) for fastening the device to the support frame (2) and a second mounting means (200a; 200b) for fastening the device to the storage means (3), the second mounting means (200a; 200b) being designed to be pushed onto, inserted into and/or latched into the first mounting means (100a; 100b) for pre-positioning of the first and second mounting means (100a; 100b; 200a; 200b) relative to one another. This enables fast belt assembly of the storage means (3), since the first and second mounting means can each be preassembled separately from one another on the support frame or storage means and can be brought together quickly and securely during the belt assembly for mounting of the storage means by fastening the second mounting means (200a; 200b) by pushing onto, insertion into and/or latching into the first mounting means (100a; 100b).
