Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an integrated mold for UAV ductwork. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are an important flight platform widely used in aerial photography, logistics delivery, and agricultural plant protection. The flight performance and stability of UAVs are crucial to their mission execution. Among these components, the ducted drive system, as a vital part of the UAV's propulsion system, plays a significant role in improving the UAV's flight efficiency and stability.

[0003] Currently, drone ducts typically consist of an outer ring, an inner ring, and a support structure between the outer and inner rings. These supports primarily connect the outer and inner rings to form a stable support structure. However, most existing supports use snap-fit ​​or screw-locking structures to fix themselves between the outer and inner rings; this method suffers from insufficient structural stability. Snap-fit ​​structures are prone to loosening under significant external forces, while screw-locking structures may also lead to overall structural instability after prolonged use due to loosening of the screws.

[0004] To address this, a production mold that can integrally form the outer ring, inner ring, and support is needed. Utility Model Content
