Fuse Mounting Drawer Structure for Blind Battery Box Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for replacing fuses in battery systems are labor-intensive and risk damaging the sealing strip, requiring removal of the battery cover and alignment with plug-in holes, which is time-consuming and increases the risk of damage to the protective sealing.
Innovation Solution
A fuse mounting structure with a drawer and guide device that allows for blind insertion of fuses into a fuse base, reducing the need for manual alignment and minimizing the workload of fuse replacement, featuring side wall, top, and bottom guide portions, and support plates for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a maintenance window with cover plate is provided on the battery box to replace fuses, then the workload of fuse replacement is reduced compared to removing the battery cover, but the fuse insertion becomes time-consuming and laborious due to alignment requirements with plug-in holes
Solution Approach 1:
A guide device is introduced as an intermediary component between the drawer and fuse base. The guide device includes guide portions that extend into the fuse base to automatically align and guide the drawer during insertion, eliminating the need for manual alignment with plug-in holes and significantly reducing insertion time
Solution Approach 2:
The guide portions are pre-positioned in the fuse base before drawer insertion. These guide portions are configured in advance to receive and align the drawer, so that when the drawer is inserted, the alignment is automatically achieved without requiring the operator to perform preliminary alignment actions
2Ease of operation
If the battery cover is removed to replace fuses, then direct access to fuses is achieved, but the sealing strip may be damaged during installation and removal, weakening the protective performance of the battery box
Solution Approach 1:
The battery box access system is segmented into multiple levels: the battery cover remains intact for overall protection, a maintenance window with cover plate provides fuse access, and a drawer within the fuse base provides fuse mounting. This segmentation allows fuse replacement without compromising the integrity of the battery cover and its sealing strip
Solution Approach 2:
The maintenance window cover plate acts as an intermediary access point between the exterior and the fuse base. It provides a dedicated opening for fuse replacement operations, allowing the battery cover to remain installed and protect the sealing strip while still enabling fuse access through the maintenance window
3Adaptability or versatility
If other components are present in the upper part of the battery box, then the battery box structure is more complete, but fuse replacement requires removal of the battery box or components, increasing complexity and risk
Solution Approach 1:
The fuse base and drawer assembly is extracted as a separate, self-contained unit within the battery box. The fuse base can be independently accessed through the maintenance window without requiring removal of other battery box components, allowing fuse replacement operations to be performed in isolation from other components
