Electric Work Vehicle Battery Cover Side-Support Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric work vehicles require a large rearward space for a support frame to stably support the cover, reducing the size and capacity of the battery.
Innovation Solution
The cover is supported by a first support portion attached to the side portion of the battery, eliminating the need for a rearward support frame, and is further stabilized by a second support portion attached to the battery's side or hanging portion, with a gap between the battery's upper end surface and the support to enhance stability and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support frame is provided rearward of the battery to support the cover, then the cover can be stably supported, but the battery size and capacity are reduced due to the space occupied by the support frame
Solution Approach 1:
The support structure transitions from a rearward support frame (occupying horizontal space behind the battery) to side support portions attached to the battery's side surfaces (utilizing vertical space along the battery sides). This dimensional shift allows the cover to be stably supported without encroaching on the battery's rearward space, thereby preserving battery capacity while maintaining support stability.
2Device complexity
If the cover is supported by the top plate portion of the battery, then the structure is simple, but the cover cannot be stably supported compared to side portion support
Solution Approach 1:
The support function is segmented from the battery's top plate portion to dedicated side support portions attached to the battery's side surfaces. This segmentation allows the support structure to leverage the stronger side portions of the battery, providing more stable cover support while maintaining relatively simple construction through the use of attached support portions rather than an integrated complex structure.

AI summary
An electric work vehicle includes a battery, a motor to be driven by electric power supplied from the battery, a cover covering the battery, and a support portion supported by the battery. The cover is supported by the support portion and swingable about a horizontal axis relative to the support portion to enable opening and closing, and the support portion is supported by a side portion of the battery.
