Seat Frame Layout for Large Battery Access in Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring a work vehicle with a body frame to accommodate a relatively large battery for improved travel performance while ensuring easy installation and maintenance, as existing designs face challenges in securing space and accessibility for the battery.
Innovation Solution
The body frame is designed with a specific structure that includes a first frame section under the seating area, a second frame section extending upward from the rear, and a third frame section extending rearward, allowing the seat frames to be detachable and the battery to be positioned between these sections, facilitating its installation and removal without hindrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a relatively large battery is installed to improve travel performance, then the travel performance is improved, but the difficulty of installation and maintenance increases due to limited space and accessibility
Solution Approach 1:
The body frame is segmented into multiple sections (first frame section, second frame section, third frame section) that create distinct spatial zones. The battery is positioned in the space between these segmented frame sections, allowing for optimized placement that balances size requirements with accessibility for installation and maintenance operations.
2Power
If the battery size is increased to improve travel performance, then the travel performance is improved, but the space availability for battery disposal becomes insufficient
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement by positioning the battery between multiple frame sections in vertical and horizontal dimensions. The first frame section is located under the seating section, the second frame section extends upward, and the third frame section extends rearward, creating a multi-dimensional space that accommodates a relatively large battery while maintaining overall vehicle compactness.

AI summary
A work vehicle according to the present invention includes a seat frame (33). A body frame includes a first frame section (21), a second frame section (22) extending upward from a rear portion of the first frame section (21), and a third frame section (23) extending rearward from an upper portion of the second frame section (22). An up-down section (33a) of the seat frame (33) is attachable to the first frame section (21) and removable therefrom, and a front-rear section (33b) of the seat frame (33) is attachable to the second frame section (22) or the third frame section (23) and removable therefrom. A battery (42) is between the up-down section (33a) and the second frame section (22) and between the front-rear section (33b) and the first frame section (21).
