Pickup Truck Bed Cover Assembly With Horizontal Opening Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pickup truck rear covers are prone to being bumped when lifted, especially with large luggage, due to their design that leaves the cover above the bed, limiting space utilization and ease of loading/unloading.
Innovation Solution
A pickup truck add-on assembly with a base, upper cover, and a driving mechanism that rotates the support arm to switch between open and closed states, allowing the cover to move horizontally and snap-fit into place, maximizing bed space and facilitating loading/unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rear cover is hinged on one side and lifted upward, then the cover can be opened, but the cover is located right above the bed making it prone to be bumped and limiting space utilization
Solution Approach 1:
The patent changes the opening dimension from vertical (above the bed) to horizontal (parallel to the bed). The support arm rotates about an axis extending front-to-rear, causing the rear cover to move horizontally away from the bed rather than vertically above it, thereby eliminating the bumping issue and maximizing vertical space utilization.
Solution Approach 2:
Instead of lifting the cover upward as in conventional designs, the patent inverts the opening motion by rotating the support arm horizontally. This inversion moves the cover away from the bed in a direction parallel to the bed surface, fundamentally changing the opening trajectory to resolve the space utilization problem.
2Ease of operation
If the rear cover is lifted upward, then the cover can be opened, but the cover is prone to be bumped when taking/placing luggage
Solution Approach 1:
The patent eliminates the harmful bumping effect by changing the opening dimension from vertical to horizontal. The cover moves parallel to the bed surface during opening, completely avoiding the vertical space above the bed where bumping would occur, thus removing the harmful factor entirely.
3Device complexity
If a conventional hinged rear cover is used, then the structure is simple, but the cover occupies space above the bed and limits loading efficiency
Solution Approach 1:
The patent maintains structural simplicity while dramatically improving loading efficiency by changing the opening motion to horizontal. The cover moves parallel to the bed, creating maximum vertical clearance above the bed for loading operations, thus resolving the contradiction between simple structure and loading efficiency.
Solution Approach 2:
The support arm is pre-positioned in a horizontal orientation during opening, which preliminarily establishes the optimal configuration for maximizing bed space utilization. This preliminary positioning ensures that the cover moves along a trajectory that inherently creates the necessary clearance for efficient loading operations.

AI summary
A pickup truck add-on assembly is provided, which includes: a base configured to be and fixedly mounted to a pickup truck bed, an upper cover, and at least one driving assembly, wherein the driving assembly comprises a driving mechanism and a support arm, the support arm being respectively hinged to the upper cover and the base, the driving mechanism being hinged to the support arm and configured to drive the support arm to rotate, so that a hinge joint between the support arm and the upper cover in an initial hinge position: i. moves from the hinge position relative to the base in a height direction; and ii. moves laterally, in a direction transverse to the height direction, from the hinge position. In addition, a pickup truck is provided having a pickup truck add-on assembly mounted thereon as described above.
