Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a structure for a magnetic quick-change mapping payload compartment for UAVs. Background Technology

[0002] Currently, drones are widely used in surveying, inspection and other fields, but low efficiency and poor accuracy in replacing payload equipment are common pain points.

[0003] Traditional mechanical buckle or bolt fixing methods require manual alignment and tightening, and are prone to misalignment due to vibration. Although electric locking mechanisms have emerged in recent years, their complex structure (including motors, transmission components, etc.) and significant weight increase affect the battery life. The industry urgently needs a quick-change solution that balances lightweight and high precision.

[0004] Therefore, existing technologies suffer from the problem that mechanical buckles are prone to wear, leading to a decrease in positioning accuracy, and threaded fasteners cannot meet the requirements for high-frequency replacement.
