Truck Cargo Box Cover with Segmented Blocks and Cross Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover apparatuses for truck cargo boxes face challenges in stable opening and closing operations due to deformation and cannot effectively cover irregularly shaped loads, leading to safety and convenience issues during transportation.
Innovation Solution
A cover apparatus with cross-shaped hinge units, variable members, and rotational driving means that allow for automatic opening and closing, and covers composed of interconnected blocks to adapt to deformed cargo box shapes and irregular loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-plate cover is used, then the structure is simple, but it cannot completely cover irregularly shaped loads and fails when cargo box deformation occurs
Solution Approach 1:
The cover is divided into multiple blocks (first cover block, second cover block, third cover block) connected by hinge assemblies, allowing each segment to independently adapt to deformation and irregular load shapes while maintaining overall cover functionality
Solution Approach 2:
The hinge assemblies enable dynamic adjustment of the cover blocks relative to each other, allowing the cover structure to flex and adapt to cargo box deformation and irregular load contours during operation
2Device complexity
If traditional hinge structures are used, then the structure is simple, but opening and closing operations become impossible when cargo box deformation occurs
Solution Approach 1:
The cross-shaped hinge structure adds a rotational degree of freedom in addition to the standard hinge movement, allowing the cover to accommodate deformation through multi-axis movement rather than being constrained to a single plane of motion
3Device complexity
If a single-plate cover is used, then the structure is simple, but transportation safety cannot be secured for irregular loads
Solution Approach 1:
The multi-block cover structure can conform to irregular load shapes more effectively than a single plate, ensuring complete coverage and preventing load scattering while maintaining structural simplicity through modular design

AI summary
The present invention relates to a cover apparatus for a truck cargo box, and more specifically to a cover apparatus for a truck cargo box, which enables stable opening and closing operations even when deformation occurs due to the deflection or warping of a truck cargo box and enables its covers to stably cover irregularly shaped loads, such as various types of wastes or scraps, thereby considerably improving transportation safety and the convenience of use. According to the present invention, there is provided the cover apparatus for a truck cargo box, which enables stable opening and closing operations via the hinges and the variable members, and enables its covers to stably cover irregularly shaped loads via the covers in each of which the plurality of blocks is connected to each other, thereby providing the effect of considerably improving transportation safety and the convenience of use.
