Pickup Work Vehicle Partition Member Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pickup-style work vehicles face inefficiencies in dumping operations due to the partition member being raised with the loading floor, restricting the height and requiring careful operation to avoid opening the rear side of the driver's section.
Innovation Solution
A pickup-style work vehicle with a partition member position change mechanism that allows the partition member to remain fixed while the loading floor moves, using a ROPS for smooth sliding and stable fixation, ensuring the partition member covers the rear side and maintains the loading floor's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the partition member is fixed to the loading floor, then the partition member can be positioned at different locations, but the partition member is moved upward together with the loading floor when the loading floor is moved to a dumping position, causing the rear side of the driver's section to open and restricting the height of the loading floor at the dumping position
Solution Approach 1:
The partition member is separated from the loading floor structure, allowing independent movement. The partition member can be adjusted to different positions along the guide rails while the loading floor moves independently for dumping operations, resolving the conflict between position adjustability and dumping efficiency
Solution Approach 2:
Guide rails are introduced as an intermediary mechanism between the partition member and the loading floor. The guide rails enable the partition member to slide smoothly to different positions while remaining independent from the loading floor's dumping movement, allowing both position adjustment and efficient dumping operations
2Adaptability or versatility
If the partition member is fixed to the loading floor, then the partition member position can be changed, but the overall height of the work vehicle becomes greater than the partition member height when the loading floor is moved to the dumping position, restricting the height of the loading floor
Solution Approach 1:
The partition member is decoupled from the loading floor structure, allowing the loading floor to achieve its full dumping height without being constrained by the partition member's position. The partition member remains at a fixed height while the loading floor moves independently to the dumping position
Solution Approach 2:
The guide rails serve as an intermediary that allows the partition member to be positioned at different locations along the loading floor without being vertically coupled to it. This enables the loading floor to reach its maximum height at the dumping position while the partition member maintains its independent positioning

AI summary
A pickup-style work vehicle comprises a driver's section, a loading floor that is located rearwardly of the driver's section and that can be moved to a dumping position, a loading floor size changeover mechanism that changes a size of the loading floor between a first state in which a front wall portion and a front bottom portion of the loading floor are moved forwardly in a fore-and-aft direction of a vehicle and a second state in which the front wall portion and the front bottom portion of the loading floor are moved rearwardly in the fore-and-aft direction, a fixing member connected to the vehicle, and partition member position change mechanism for changing the position of the partition member in the fore-and-aft direction of the vehicle between a forward position and a rearward position. The partition member when placed at the forward position is located immediately forwardly of the loading floor in the first state while the partition member when placed at the rearward position is located immediately forwardly of the loading floor in the second state.
