Battery Mounting Base Groove Structure for Liquid Film Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Batteries are prone to short circuiting due to the formation of a liquid film between the mounting base and the insulating member, which can cause electrical connection and failure of insulation protection.
Innovation Solution
A flow guiding groove is incorporated into the mounting base, increasing the distance between the mounting base and the insulating member, preventing the formation of a continuous liquid film and reducing the risk of electrical connection, thereby enhancing insulation protection and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mounting base is placed close to the insulating member to reduce space, then the device complexity is reduced, but a liquid film can form between them causing electrical connection and short circuiting
Solution Approach 1:
The patent divides the contact surface between the mounting base and insulating member by introducing grooves (first groove, second groove, third groove) that segment the potential liquid film path into isolated sections, preventing continuous liquid bridges while maintaining close proximity
Solution Approach 2:
The grooves act as intermediary structures that physically interrupt the liquid film formation path, serving as barriers that prevent direct electrical connection through liquid while allowing the mounting base and insulating member to remain closely positioned
2Reliability
If the distance between the mounting base and insulating member is increased to prevent liquid film formation, then the insulation reliability is improved, but the device complexity and space occupation increase
Solution Approach 1:
Instead of increasing overall distance, the patent segments the contact interface using grooves that create isolated zones, maintaining close spacing while preventing continuous liquid paths through strategic division of the interface area
3Volume of moving object
If the mounting base and insulating member are placed close together, then the battery compactness is improved, but the risk of short circuiting through liquid film increases
Solution Approach 1:
The grooves segment the liquid film formation area into isolated sections, allowing compact positioning while preventing continuous conductive liquid paths that would cause short circuits
Solution Approach 2:
The grooves serve as intermediary barrier structures that physically block liquid film continuity, enabling close spacing without increasing short circuit risk

AI summary
The present application provides a mounting base, a battery and a power consuming device, which relate to the technical field of batteries. The mounting base may be configured to be connected to an end plate and an output electrode, and an insulating structure may be provided on one side of the end plate and configured to insulate the end plate from a battery cell. The mounting base may include a main body provided with a flow guiding groove on the side facing the insulating structure. The flow guiding groove may be configured to prevent an electrical connection between the output electrode and the end plate by means of a liquid between the main body and the insulating structure.
