Bike Frame Battery Locking Assembly With Anti-Fall Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric bicycle battery modules often fall off when dismounted due to lack of supporting force, potentially causing damage if not noticed in time.
Innovation Solution
A fixing device with a locking member and anti-fall assembly, featuring a stopper, pressing member, and resilient assembly, which provides axial support to prevent the battery module from falling, allowing for secure locking and unlocking while minimizing the risk of accidental drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the battery module is provided on the down tube or inside the tube to keep simple appearance, then the appearance simplicity is improved, but the battery module may suddenly fall off without supporting force when dismounted
Solution Approach 1:
The fixing device is divided into separate functional components: a locking member for securing the battery module, and an anti-fall assembly with stopper and resilient assembly for preventing drops. This segmentation allows each component to perform its specific function effectively while maintaining overall simplicity.
Solution Approach 2:
The anti-fall assembly provides preliminary support force to counteract the battery module's weight before actual detachment occurs. The resilient assembly pre-positions the stopper to resist downward movement, preventing accidental drops during the unlocking process.
2Ease of operation
If the pressing member is located on the locking member side, then the unlocking operation is simpler, but the battery module may fall to the ground due to negligence
Solution Approach 1:
The pressing member acts as an intermediary element that transfers the user's pressing force to the stopper through the resilient assembly. By positioning it on the battery module side, it mediates between the user's action and the locking mechanism, ensuring controlled release while maintaining support.
Solution Approach 2:
The resilient assembly automatically maintains the stopper in a supportive position during the unlocking process. The system self-regulates the support force, ensuring the battery module remains supported throughout the operation without requiring additional user attention or action.
3Ease of operation
If the stopper is separated from the supporting surface during unlocking, then the battery module can be released, but the battery module may fall without sufficient supporting force
Solution Approach 1:
The resilient assembly provides dynamic support by allowing the stopper to maintain contact with the supporting surface throughout the unlocking process. The elastic nature of the resilient assembly ensures continuous adaptive support, adjusting to the forces applied during release while preventing sudden drops.
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 device effectively secures the battery module to the bike frame, preventing falls and damage by providing sufficient support through the resilient assembly, even when the user is not actively holding it during unlocking.
Implementation Method 1
a resilient assembly mounted on the locking member. The resilient assembly axially forms a protruding portion, and the protruding portion has a supporting surface
Implementation Method 2
The pressing member has a pressing portion, a pivoting portion and a pushing portion, and the pivoting portion is located between the pressing portion and the pushing portion and is transversely pivoted on an end surface

AI summary
A fixing device for a battery module (200) includes a locking member (100) and an anti-fall assembly. The locking member (100) is arranged in a tube body of a bike frame and in axial abutment with the battery module (200). The anti-fall assembly includes a pressing member (310) below the stopper (300), a resilient assembly (110) being provided on the locking member (100), and a stopper (300) protruding from an end surface. The anti-fall assembly can provide sufficient supporting force to the stopper (300) through the resilient assembly (110), which is able to prevent the battery module (200) falling from the locking member (100) when it is unlocked. The pressing member (310) pushing towards the resilient assembly (110) to allow the stopper (300) being separated from the supporting surface (114) and releasing the battery module (200) from the fixing device.
