Removable Battery Holder with Quick-Release Handle for E-Bikes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery holder devices for electric bicycles are difficult to disassemble and reassemble, requiring mechanical tools, making maintenance and recharging cumbersome, and the batteries are prone to theft due to their bulkiness and high value when left unattended.
Innovation Solution
A removable and sealed battery holder with a quick-action engaging and disengaging mechanism, featuring a handle that pivots to release the mechanical coupling, allowing easy detachment from the bicycle frame and incorporating a locking mechanism for security, enabling portable recharging and improved stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical fastening means (U-bolts, clamps, screws) are used to fix the battery holder, then the battery holder is securely fixed to the frame, but the disassembly and reassembly operations become difficult and require mechanical tools
Solution Approach 1:
The fastening system is divided into separate coupling means on the battery holder and counter-means on the frame, allowing independent manipulation of each component during assembly and disassembly operations
Solution Approach 2:
The fastening system transitions from a static fixed state to a dynamic state that can easily switch between assembled and disassembled configurations through the quick-action release mechanism, enabling rapid transformation between states
2Stability of the object's composition
If the battery holder is permanently mounted on the bicycle, then the structure is stable, but the batteries cannot be easily removed for recharging or replacement
Solution Approach 1:
The battery holder is designed with a dynamic fastening system that can transition between a locked stable state during operation and an easily removable state for recharging, allowing the structure to adapt between these two functional requirements
3Ease of operation
If the batteries are left mounted on the bicycle in external locations, then they are readily accessible, but they are prone to theft or vandalism due to their high value
Solution Approach 1:
The batteries can be extracted from the bicycle frame by removing the battery holder, allowing them to be taken indoors for charging and storage, thereby separating them from public external locations where theft or vandalism could occur

AI summary
The invention relates to a battery holder device (1) for an electric bicycle (2), for example of the type with pedal assist by means of an electric motor. Such a battery holder device is designed to be housed inside a corresponding housing seat associated with the frame of the bicycle and to be connected to the electric motor of said bicycle. For this purpose, the battery holder device has a box-like body (20) having the structure of a removable rigid bag provided with a concealable-type handle (27); housing inside the corresponding seat is performed by means of snap-engagement of mechanical means and counter-means which comprise the said handle (27); an electrical connection with the motor (3) is established by means of coupling together of electrical connectors (17) provided in the box-like body (20) and in the housing seat.
