Electric Storage Apparatus Circuit Module Engagement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric storage apparatuses, such as those used in hybrid and electric vehicles, face challenges in easily detaching and replacing circuit modules, particularly cell monitor units, which are also susceptible to damage and static electricity due to their exposure and complex detachment processes.
Innovation Solution
The design incorporates an engagement and disengagement mechanism between the enclosure and circuit modules, allowing for easy detachment and attachment of the circuit modules, including the use of elastic engaging portions and concave engaged portions to enhance stability and prevent static electricity exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cell monitor unit is integrated into the cell module structure, then the monitoring function is stable and reliable, but the replacement and detachment of the cell monitor unit becomes cumbersome and complicated
Solution Approach 1:
The invention divides the cell monitor unit into a separate detachable module that can be independently removed from the cell module. The connection structure is segmented into a connection portion on the cell module and a corresponding engaged portion on the cell monitor unit, allowing the monitor unit to be replaced without affecting the battery cells or other components.
Solution Approach 2:
The cell monitor unit is extracted as a separate replaceable component from the integrated cell module structure. This extraction allows the monitoring function to be maintained while enabling easy removal and replacement of the monitor unit by simply disengaging the connection portion and engaged portion.
2Ease of operation
If the cell monitor unit is exposed for easy access, then the replacement operation is simplified, but the unit becomes susceptible to static electricity damage
Solution Approach 1:
The invention introduces a cover structure that encloses the cell monitor unit when attached to the cell module. This cover acts as a protective shell that shields the electronic components from static electricity and other environmental hazards while allowing the unit to be easily accessed by detaching the entire cell monitor unit through the engagement mechanism.
3Reliability
If the cell monitor unit is firmly fixed to ensure stable monitoring, then the monitoring reliability is improved, but the detachment and replacement process becomes complex
Solution Approach 1:
The connection structure employs a dynamic engagement mechanism where the engaged portion can be easily inserted into and removed from the connection portion. This dynamic design provides stable fixation during operation while allowing simple detachment when needed, avoiding complex fastening procedures.
Solution Approach 2:
The engagement structure is designed to be self-aligning and self-locking, where the engaged portion automatically fits into the connection portion without requiring precise manual alignment or additional tools. This self-service mechanism ensures stable monitoring while simplifying the replacement process to a straightforward insert-and-lock operation.
