Pickup Bed Cover Hinge Seal Structure for Waterproof Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pickup truck covers have issues with water leakage due to gaps in the rotating shaft structure, which are prone to damage and do not provide adequate waterproofing, especially when the front part is frequently opened.
Innovation Solution
A rotating shaft structure with a hinge assembly and intermediate rubber strips that form a waterproof seal, utilizing the elasticity of the rubber strips to fill gaps and provide a smooth rotation mechanism, along with a water-catching groove to manage any leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating shaft structure is used to allow frequent opening of the rear part, then the ease of operation is improved, but the reliability deteriorates due to the rotating shaft structure being vulnerable to damage
Solution Approach 1:
The patent replaces the rigid rotating shaft structure with a flexible hinge assembly comprising a hinge body, hinge pin, and hinge buffer. The hinge buffer acts as a flexible element that absorbs stress and prevents damage to the rotating shaft structure during frequent opening operations, thereby improving reliability while maintaining ease of operation.
2Ease of operation
If gaps are ensured in the rotating shaft structure to enable rotation, then the ease of operation is improved, but the object-affected harmful factors worsen due to water leakage
Solution Approach 1:
The patent introduces an intermediate rubber strip as a mediator between the rotating parts. This rubber strip fills the gaps necessary for rotation while providing waterproof sealing, thus eliminating water leakage without compromising the rotation capability of the hinge assembly.
3Object-affected harmful factors
If the hinge assembly is added to improve waterproofing, then the object-affected harmful factors are reduced, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the hinge assembly: the hinge body provides rotation, the hinge pin provides structural support, the hinge buffer provides shock absorption and protection, and the intermediate rubber strip provides waterproofing. By combining these elements into a single integrated hinge assembly, the patent achieves comprehensive waterproofing without proportionally increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures smooth operation and enhanced waterproofing of the rotating shaft structure, preventing water ingress and prolonging the structure's lifespan.
Implementation Method 1
the intermediate rubber strips have a certain degree of elasticity that can be squeezed, their ability to be squeezed is utilized to make up for the gaps generated between the profiles
Implementation Method 2
adding a hinge to the conventional rotating shaft structure and utilizing the hinge to drive the two rotating cavities to rotate relative to each other
