Traction Battery Mounting Brackets With Sliders for Fast Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mounting traction batteries in vehicles, such as trucks, are complex and inefficient, requiring careful lowering and fitting into a cage-like frame, which complicates both production and maintenance processes.
Innovation Solution
A system featuring front and rear bracket members with sliding surfaces, where sliders are attached to the battery and mate with the bracket members, allowing for easy horizontal placement and removal using a pallet lifter, along with a stabilizing element and crash protection structure for secure and protected installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cage-like frame structure is used to mount the battery, then the battery is securely held and protected, but the installation process becomes complex and time-consuming requiring careful lowering and fitting
Solution Approach 1:
The cage-like frame is segmented into separate bracket members (front bracket, rear bracket, side brackets) that are spaced apart and interconnected. Each bracket can be independently positioned and secured to the vehicle frame, simplifying the overall assembly process while maintaining structural integrity and battery security
Solution Approach 2:
Sliders are introduced as intermediary components between the battery and the bracket members. These sliders enable easy horizontal movement and positioning of the battery during installation and removal, eliminating the need for complex lowering and fitting operations into a rigid cage structure
2Reliability
If a cage-like frame structure is used to mount the battery, then the battery is securely held and protected, but the installation time increases due to complex procedures
Solution Approach 1:
The mounting system incorporates sliders that enable dynamic horizontal movement of the battery during installation and removal. This dynamic capability allows the battery to be easily positioned and secured without time-consuming manual alignment and fitting procedures required by rigid cage structures
Solution Approach 2:
The frame is divided into separate, spaced-apart bracket members that can be independently installed and adjusted. This segmentation allows for more flexible and faster assembly compared to assembling a complete cage-like structure before battery installation
3Ease of operation
If sliders are attached to the battery before mating with bracket members, then horizontal placement is enabled, but the battery must be precisely positioned
Solution Approach 1:
The sliders are designed to be self-aligning components that automatically find their correct position on the bracket members during horizontal movement. The sliding surfaces and mating geometries are configured so that the battery-guide-slider assembly self-corrects minor positioning errors, eliminating the need for high-precision pre-alignment

AI summary
A system for installation of traction batteries for a vehicle having a chassis comprising at least one load-carrying frame member. A front bracket member and a rear bracket member are adapted to be secured to and project from the frame member of the vehicle for receiving a traction battery between the front bracket member and the rear bracket member. The system also comprises a first and a second slider adapted to be connected to a front and a rear side, respectively, of a traction battery. The sliders are adapted to be mated with the bracket members subsequently to the sliders having been connected to the traction battery, thereby enabling the traction battery by means of the connected sliders to be received by the bracket members and be moved towards the frame member of the vehicle.
