UAV Battery Assembly with Clamp Button and Elastic Return Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing designs for unmanned aerial vehicles (UAVs) make it inconvenient to replace batteries due to the need to unscrew and reattach screws or bolts, which complicates the battery replacement process.
Innovation Solution
A battery assembly with a clamp button and restorable elastic piece that allows for detachable connection to the UAV's main body, enabling easy battery replacement by using a clamping mechanism that automatically returns to its original position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or bolts are used to fasten the battery to the main body, then the battery is securely fixed and cannot drop during flight, but the battery replacement process becomes inconvenient and time-consuming
Solution Approach 1:
The fastening system is segmented into a clamp button mechanism that can be independently operated. The clamp button is divided into a pressing portion (for user operation) and a clamping portion (for securing the battery), allowing the battery to be quickly released by simply pressing the button without dealing with multiple screws or bolts.
Solution Approach 2:
The clamp button incorporates an elastic component that provides dynamic movement. The elastic piece allows the clamp button to move between a released state (when pressed) and a clamped state (when released), enabling quick battery replacement while maintaining secure fixation during flight.
2Reliability
If a sealing board with screws is used to prevent battery dropping, then the battery is securely held in the cavity, but the structure becomes more complex and replacement requires unscrewing multiple fasteners
Solution Approach 1:
The invention extracts the essential fastening function from the complex sealing board structure. Instead of using a rigid sealing board with multiple screw holes, the patent uses a clamp button that can be pressed to release and automatically returns to secure the battery, simplifying the overall structure while maintaining retention reliability.
Solution Approach 2:
The elastic piece in the clamp button mechanism provides self-service functionality. When the clamp button is pressed to release the battery, the elastic piece automatically returns the clamp button to its original clamped position, eliminating the need for manual manipulation of multiple fasteners and reducing structural complexity.
