Truck Chassis Frame Mounting Module for Battery Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck chassis frames do not efficiently utilize space for mounting batteries and components, particularly in hydrogen-electric trucks, due to the presence of crossmembers that fill empty spaces between side rails, which reduces body stiffness when attempting to create space for batteries.
Innovation Solution
A truck chassis frame design featuring a mounting module connected between a front frame and a rear frame, providing a dedicated mounting space with reinforcing members and connecting members to ensure structural integrity and accommodate additional batteries and components, enhancing space utilization and vehicle stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If crossmembers are removed from sections of the existing truck chassis frame to create space for batteries, then space utilization is improved, but body stiffness is reduced
Solution Approach 1:
The chassis frame is divided into a front frame, a rear frame, and a mounting module connected between them. This segmentation allows the mounting module to be specifically designed with a mounting space for batteries, while the front and rear frames maintain structural integrity and stiffness.
Solution Approach 2:
A mounting module is introduced as an intermediary component between the front frame and rear frame. This mounting module contains the mounting space for batteries and is connected to the main frame structure through connecting members, thereby creating battery space without compromising the overall chassis stiffness.
2Quantity of substance
If a cargo container is disposed on the truck chassis frame, then cargo capacity is improved, but space above the chassis frame for mounting batteries is lost
Solution Approach 1:
The mounting space for batteries is created in the longitudinal direction between the front and rear frames, rather than in the vertical space above the chassis. This dimensional shift allows battery mounting without interfering with cargo container placement.
Solution Approach 2:
The chassis is segmented into functional zones: the front and rear frames for structural support and cargo carrying, and the mounting module between them for battery placement. This segmentation allows simultaneous optimization of cargo capacity and battery space.
3Ease of manufacture
If the existing truck chassis frame design is used, then manufacturing simplicity is maintained, but space utilization for batteries and components is insufficient
Solution Approach 1:
The mounting module is designed as a universal component that can be applied to different truck types (hydrogen-electric, diesel-engine, and electric trucks). The module includes a mounting space for batteries and can also accommodate other components, providing multi-functionality while maintaining manufacturing simplicity.
Solution Approach 2:
The chassis frame is segmented into a front frame, rear frame, and mounting module. This modular segmentation allows the mounting module to be independently designed and manufactured with optimized space utilization, while the overall structure remains simple to manufacture.
