Portable Battery Charger With Buffer Mechanism For Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery chargers for heavy portable batteries in electric vehicles face challenges in minimizing the load on terminal portions during battery fitting, which can lead to impact and damage.
Innovation Solution
A charger design featuring a movable stage with a buffer mechanism and guide mechanisms that slow down the battery's fitting speed and distribute the load evenly, ensuring the terminal portion is protected from impact and stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the battery is directly fitted to the terminal portion without a buffer mechanism, then the fitting process is simple and quick, but the heavy battery causes impact and excessive load on the terminal portion
Solution Approach 1:
The buffer mechanism is pre-installed on the stage to cushion the battery before it reaches the terminal portion. The buffer member is positioned to contact the battery during fitting, absorbing impact energy and reducing the load on the terminal portion while maintaining a relatively simple fitting process
2Device complexity
If the terminal portion is positioned directly below the stage, then the structure is compact, but the heavy battery creates excessive load and potential damage during fitting
Solution Approach 1:
The buffer mechanism serves as an intermediary element between the battery and the terminal portion. It is installed on the stage and contacts the battery during fitting, mediating the force transmission and protecting the terminal portion from direct impact while maintaining the compact vertical arrangement
3Device complexity
If the battery is placed on a fixed stage, then the structure is simple, but the battery cannot be properly guided or positioned during fitting
Solution Approach 1:
The stage is designed to move vertically in response to battery placement. When the battery is placed on the stage, the stage moves downward together with the battery, allowing the buffer mechanism to engage and the battery to be properly guided into the terminal portion, improving positioning accuracy while maintaining structural simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The charger effectively reduces the load on the terminal portion during battery fitting, preventing impact and enhancing durability while ensuring smooth and balanced fitting, even when the battery is inserted at incorrect angles.

AI summary
A charger for a portable battery includes a stage (8) on which a portable battery (45) used in an electric vehicle can be placed, and a terminal portion (9) that is provided at a position on a side opposite to a position on a side on which the battery (45) is to be placed with respect to the stage (8) in a state in which the battery (45) is not placed on the stage (8). The stage (8) moves together with the battery (45) to fit the battery (45) to the terminal portion (9) when the battery (45) is placed on the stage (8). The charger further includes a buffer mechanism (10) that suppresses a fitting speed of the battery (45) to the terminal portion (9) when the battery (45) is placed on the stage (8).
