Work Vehicle Partition Wall Layout for Rear Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work vehicles, the partition wall configuration between the driver's seat and the rear region obstructs rearward visibility and can lead to inadvertent operation of tools due to its extensive length and orientation, which does not effectively prevent operator hand intrusion from the rear region.
Innovation Solution
The partition wall is offset towards the side where the operation tools are disposed, and a side partition wall is inclined and protrudes further outward than the tools, reducing the wall's length and enhancing rearward visibility while preventing tool contact and intrusion by rerouting the operator's hand.

Engineering Contradiction Analysis
1Reliability
If the partition wall is configured to have a length that covers the entire area between both prop frame portions, then operator hand intrusion is prevented, but rearward visibility is deteriorated
Solution Approach 1:
The partition wall is divided into two segments: a first partition wall extending from the front surface of the lower end of the prop frame portions to a position below the driver's seat, and a second partition wall extending laterally outward from the lower end of the first partition wall. This segmentation allows the partition to prevent hand intrusion while improving rearward visibility by creating gaps and redirecting hand paths.
2Reliability
If the auxiliary partition wall is disposed in an orientation along the front-rear direction, then intrusion prevention is provided, but the distance of rerouting outward is not shortened
Solution Approach 1:
The second partition wall extends in a lateral direction outward of the vehicle body from the lower end of the first partition wall, rather than continuing in the front-rear direction. This dimensional change redirects operator hands laterally, shortening the rerouting distance and improving accessibility while maintaining intrusion prevention.

AI summary
A work vehicle includes an driver's seat 17 disposed in the rear region of a vehicle body, a left and a right fender 7 that are disposed on the left and right laterally outward sides of the driver's seat 17, and a partition wall 80 that divides, at a position behind the driver's seat 17, the vehicle body into a front region of the vehicle body on the front side of the partition wall and a rear region of the vehicle body on the back side thereof. Operation tools 66, 67 for operating working equipment provided on the vehicle body are disposed on one of the fenders 7, and the partition wall 80 is provided offset toward a side where operation tools 66, 67 are disposed relative to the driver's seat 17.
