UAV Wing Locking Assembly for Fast Detachable Rigid Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between the body and wings of unmanned aerial vehicles requires reliability in strength and rigidity without affecting flight performance, while also enabling easy and fast disassembly and assembly.
Innovation Solution
A detachable connection system is implemented using first and second connection portions, where the first connection portion includes a latch member with a protrusion and the second connection portion features a guide groove and mounting groove, allowing for engagement and locking through rotation or sliding, with additional features like limiting members and electrical connectors for enhanced stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable connection system is used between body and wings, then ease of assembly and disassembly is improved, but connection strength and rigidity may deteriorate
Solution Approach 1:
The connection system is divided into multiple independent components: a latch member with protrusion for quick engagement, a locking member with guide groove and mounting groove for staged connection, and limiting members for position control. This segmentation allows the system to achieve both easy operation through modular design and strong connection through multiple engagement points working together.
2Ease of operation
If a latch sliding pin with spring is used for quick disassembly and assembly, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring component traditionally used to provide automatic rebound force is completely removed from the design. Instead, the latch member relies on its own elastic deformation capability to provide the necessary rebound force during engagement and disengagement. This extraction of the spring simplifies the overall device structure while maintaining the quick operation functionality.
Solution Approach 2:
The latch member is designed with specific local elastic properties - it has sufficient elasticity to provide rebound force during operation, yet maintains high rigidity when engaged to ensure strong connection. This localized quality differentiation allows a single component to fulfill multiple functional requirements without adding complexity.

AI summary
The present invention discloses an unmanned aerial vehicle, including a body and wings. A first connection portion is disposed on one of the body and the wing. A second connection portion is disposed on the other of the body and the wing. The first connection portion and the second connection portion are detachably connected. The first connection portion is engaged with the second connection portion. The body and the wing are locked by rotating or sliding the second connection portion. The body can be conveniently assembled with or disassembled from the wing and the connection part meets the reliability of strength and rigidity and does not affect the flight performance.
