Bicycle Battery Support Frame With Interlock Mount for Pack Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric bicycles lack efficient and adaptable mechanisms for securely mounting and powering battery packs, particularly for accommodating different voltage and weight capacities, which limits their performance and usability.
Innovation Solution
A battery support frame with a removably coupled interlock interface and support rails that integrates with the bike's frame, allowing for secure mounting and electrical connection of battery packs, accommodating varying voltage and weight capacities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed battery mount is used in existing electric bicycles, then the mounting structure is simple, but it cannot accommodate different voltage and weight capacities of battery packs
Solution Approach 1:
The battery mount is divided into multiple segments including a first portion, a second portion, and a battery support frame. Each segment can independently adjust or be configured to accommodate different battery pack sizes and weights, allowing the system to adapt to various battery capacities without requiring a completely different mounting structure for each battery type.
Solution Approach 2:
The battery support frame includes adjustable components such as support rails that can be positioned at different locations along the mount structure. This dynamic adjustability allows the mounting system to adapt to different battery pack dimensions and weight distributions, providing versatility while maintaining a relatively simple overall structure that doesn't require complete redesign for different battery configurations.
2Ease of operation
If a removable interlock interface is used, then the battery pack can be easily installed and removed, but the connection reliability may be compromised
Solution Approach 1:
The interlock interface is designed as a separate, removable component that can be easily engaged and disengaged from the battery pack and mount structure. This extraction of the locking mechanism allows users to quickly install and remove battery packs while the interlock design itself incorporates features to maintain reliable electrical connections during operation, resolving the contradiction between ease of operation and connection reliability.
3Strength
If the battery mount is integrated into the side panels, then the overall structure is compact, but the battery support and electrical connection may be insufficient for larger battery packs
Solution Approach 1:
The battery mount structure merges the side panel integration with an extended battery support frame that includes reinforcement elements. The first and second portions of the mount are coupled to the side panels while the battery support frame provides additional structural strength and mounting points. This merging approach maintains the compact overall structure while enhancing the battery support capability to handle larger and heavier battery packs.

AI summary
A battery mount includes a first portion, a second portion selectively coupled to the first portion, a battery connection interface defined by the first and second portions, and a connection terminal supported within the battery connection interface. A battery support frame defines a support rail configured to be positioned within the battery connection interface. The battery support frame is configured to be removably coupled to the battery mount by an interlock interface defined by the first and second portions of the battery mount and the battery support frame. A battery pack is selectively received within the battery connection interface. The battery pack includes a corresponding interface that interacts with the battery connection interface, the support rail, and the connection terminal to provide a mechanical and an electrical interface between the battery pack and the battery mount to selectively provide power to a drive module.
