Rotating Protective Cover for Sealed Energy Storage Control Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The control box in energy storage devices is prone to failure due to the entry of impurities from the external environment, particularly through switch assemblies, which lack effective waterproof and dustproof measures, leading to potential damage and malfunction.
Innovation Solution
A control box design featuring a protective cover that rotates relative to the wall via a first connecting member and is fixedly connected through detachable second connecting members, with optional grooves and shielding structures to accommodate and shield the switch assembly, enhancing waterproof and dustproof capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective cover is completely detached for switch assembly operation, then accessibility is improved, but the risk of losing the protective cover and compromising waterproof/dustproof protection increases
Solution Approach 1:
The connection between protective cover and control box is segmented into two independent systems: a first connecting member providing rotatable connection for easy access, and a second connecting member providing detachable fixed connection for secure sealing. This segmentation allows the system to switch between accessibility and protection modes without compromising either function.
Solution Approach 2:
The protective cover transitions from a static fully-detached design to a dynamic system with two connection states: rotatable connection via the first connecting member for operational access, and fixed connection via the second connecting member for sealed protection. This dynamic capability resolves the contradiction between ease of operation and reliability of protection.
2Reliability
If the protective cover is fixedly connected to maintain waterproof and dustproof effect, then protection reliability is improved, but accessibility for operation and maintenance deteriorates
Solution Approach 1:
The fixed connection system is segmented by introducing a second detachable connecting member that works in conjunction with the first rotatable connecting member. This allows the protective cover to be securely fixed for protection while enabling easy detachment for maintenance, resolving the contradiction between fixed connection reliability and operational accessibility.
3Ease of operation
If the protective cover is completely detached for access, then ease of operation is improved, but the possibility of impurity entry and component damage increases
Solution Approach 1:
The connection system is segmented into two members: the first connecting member enables access by allowing rotation, while the second connecting member maintains sealing when engaged. This segmentation ensures that operational access does not compromise the waterproof and dustproof barriers, preventing impurity entry while maintaining ease of operation.
4Ease of operation
If the protective cover structure is simplified for easy detachment, then ease of operation is improved, but the risk of losing components and reducing protection increases
Solution Approach 1:
The connection system is divided into two independent connecting members with distinct functions. The first connecting member provides rotatable connection for easy access, while the second connecting member provides detachable fixed connection for secure sealing. This segmentation allows simple detachment operations while maintaining protection integrity through the dual-connecting-member design.

AI summary
An energy storage device and a control box therein are disclosed. The control box includes a first wall, a switch assembly mounted on the wall, and a protective cover positioned over the switch assembly. The cover is rotatably connected to the first wall by a first connecting piece and secured in place by a detachable second connecting piece. This structure reduces the risk of environmental contaminants entering the control box when the switch assembly is not in use, thereby enhancing device reliability. When operation or maintenance is required, the protective cover can rotate relative to the wall without being fully removed, minimizing the risk of misplacement and improving ease of access. This design provides effective protection of the switch assembly and helps reduce control box failure.
