Luggage Board Movement Mechanism Simplified Guide Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement mechanisms for luggage boards in vehicle compartments require complex structures with biasing members like springs, complicating the design and increasing the number of parts.
Innovation Solution
A simplified mechanism using guide parts and support parts on the vehicle's sidewalls, with guide pins that move along inclined and horizontal grooves, allowing the luggage board to shift between upper and lower positions without a valve member, utilizing a rear board support as a pivot point for rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a valve member and biasing member (spring) are used to allow the guide protrusions to move along the guide groove, then the luggage board can shift between upper and lower positions, but the structure becomes complex and the number of parts increases
Solution Approach 1:
The invention extracts and eliminates the valve member and biasing member from the movement mechanism. By removing these components, the patent achieves the same functional result (luggage board position shifting) with a simpler structure that uses only guide grooves and guide protrusions, directly resolving the technical contradiction between ease of operation and device complexity
Solution Approach 2:
The guide protrusions are designed to automatically engage with and move along the guide grooves without requiring external actuation mechanisms. The luggage board's own weight and movement provide the necessary force for the guide protrusions to follow the guide groove path, eliminating the need for springs or valves to control the movement
2Ease of operation
If a valve member is used to bridge the inclined groove, then the guide protrusions can move smoothly between inclined and horizontal grooves, but the structure becomes more complex
Solution Approach 1:
The invention merges the inclined groove and horizontal groove into a single continuous guide groove structure. The guide groove is designed with a smooth transition that allows guide protrusions to move seamlessly from the inclined section to the horizontal section without requiring a separate valve member to bridge the gap, thus simplifying the overall structure while maintaining smooth movement
Solution Approach 2:
Instead of using a valve member to actively control and bridge the transition between grooves, the invention inverts the approach by designing the guide groove itself to provide the bridging function through its geometric configuration. The guide groove's shape naturally guides the protrusions through the transition zone without additional components

AI summary
A movement mechanism for a luggage board capable of dividing a vehicle luggage compartment into upper and lower parts is provided, the movement mechanism having a more simplified structure and allowing the luggage board to be shifted between upper and lower positions with a simple operation. Sidewalls (15) positioned on either side of the luggage compartment (3) in the vehicle width direction are each provided with: a guide part (17) for guiding guide protrusions (11) when a luggage board (5) moves between the upper and lower positions; and a support part (21) for supporting the luggage board (5). The guide part (17) has: a lower guide section (17a) inclined such that a vehicle rear side thereof is positioned above a vehicle front side thereof; and an upper guide section (17b) extending toward the front of the vehicle from the end of the lower guide section (17a) on the vehicle rear side. The support part (21) is provided on each sidewall (15) of the luggage compartment (3) more toward the rear of the vehicle than an intersection part between the lower guide section (17a) and the upper guide section (17b) on the vehicle rear side.
