Elastic Battery Case for Electric Skateboard Deck Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a battery case under the deck of an electric skateboard interferes with the elastic deformation of the deck, potentially causing damage and leading to unbalanced battery management and reduced battery life.
Innovation Solution
A battery case design featuring side plate parts with integrated or assembled elastic elements, allowing for elastic deformation by compressing when pressure is applied, and a connecting mechanism to secure the case under the deck, ensuring the deck's elastic deformation is maintained without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery case is mounted under the deck, then the battery can be securely held and powered, but the elastic deformation of the deck is interfered with and may cause damage
Solution Approach 1:
The battery case is divided into a bottom plate and two side plates that can independently deform, allowing the structure to accommodate deck elastic deformation while maintaining battery security
Solution Approach 2:
The side plates are designed with elastic elements that change their rigidity parameters, allowing them to be rigid enough to hold batteries securely but flexible enough to deform with the deck under elastic loads
2Strength
If the battery case is divided into two parts mounted at the ends of the deck, then the influence on deck elastic deformation is reduced, but battery management becomes difficult and battery life is shortened
Solution Approach 1:
The battery case merges the bottom plate and side plates into a single integrated structure that maintains overall rigidity for secure battery holding while allowing localized elastic deformation through the flexible side plates, thus improving battery management compared to completely divided structures

AI summary
This invention relates to a battery case and an electric skateboard using same. The battery case comprises a bottom plate part and two side plate parts extending oppositely from the bottom plate part, wherein each of the side plate parts has at least one opening, in which an elastic element is arranged. The electric skateboard comprises a bearing deck, wheels mounted on both ends of the bearing deck, an electric motor mounted under the bearing deck, and said battery case which is mounted under the bearing deck. The side plate parts of the battery case have openings in which elastic elements are arranged. Therefore, when pressure is exerted by the bearing deck to the battery case, the opening of the battery case is able to squeeze the elastic element so that the battery case can undergo an elastic deformation easily.
