Generator Enclosure Hinge Layout for Wind-Stable Cover Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing generator set enclosures face issues with cover plates being blown shut by strong winds due to their design, leading to instability and potential safety hazards, and the hinge structures deteriorate over time, compromising the connection between the cover and the case.
Innovation Solution
A case design with a cover plate and hinge mechanism that positions the mass center above the enclosure's top surface, reducing windward area and using reinforcing beams and connecting assemblies to enhance wind resistance and stability, while keeping the hinge mechanism internal to prolong its life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover plate uses a conventional hinge structure with smaller opening angle, then the cover plate can be opened, but the barycenter becomes higher and windward area increases, causing the cover plate to be blown shut by strong wind
Solution Approach 1:
The patent positions the barycenter of the cover plate below the bottom surface of the case body by extending the hinge mechanism downward. This creates a counterbalancing effect where gravity acts as a stabilizing force, preventing the cover plate from being blown shut by wind while maintaining ease of operation.
Solution Approach 2:
The hinge mechanism is extended in the vertical dimension below the case body, moving the barycenter from a higher position to a lower position. This dimensional change fundamentally alters the wind resistance characteristics while preserving the cover plate's operability.
2Ease of operation
If the hinge structure is exposed on the case, then the cover plate can be connected and opened, but the hinge structure deteriorates over time, causing unstable connection
Solution Approach 1:
The hinge mechanism is nested within the case body structure, with the hinge arranged inside the case and extending downward. This internal positioning protects the hinge from environmental exposure and deterioration while maintaining its connection function between the cover plate and case.
Solution Approach 2:
The hinge mechanism is extracted from the conventional exposed position and repositioned internally within the case structure. This extraction removes the hinge from harmful environmental exposure, preventing deterioration while preserving operational functionality.
3Ease of operation
If the cover plate has larger windward area for easier opening, then the cover plate can be opened wider, but strong wind can move the cover plate and flip the case over
Solution Approach 1:
By positioning the barycenter below the case body through the extended hinge mechanism, gravity creates a stabilizing moment that counteracts the overturning moment generated by wind force on the cover plate, preventing case flipping while maintaining operational accessibility.

AI summary
Systems of the present disclosure provide a chassis and a generator set, including a cabinet, a cover plate and hinge mechanisms. Each hinge mechanism includes a first connection seat, a second connection seat and a connection assembly. The first connection seat is arranged on the cover plate, and a slider is arranged on the first connection seat. The second connection seat is arranged in the cabinet, and the length of the second connection seat is less than the length of the first connection seat. When the cover plate is at the maximum opening and closing position, the center of mass of the cover plate is located above the top surface of the cabinet and close to the top surface of the cabinet.
