Abstract

This utility model discloses a power anti-torsion device for a large cargo drone, belonging to the technical field of drone power anti-torsion equipment. It includes a main structure, which is horizontally embedded and connected to the drone fuselage. A rivet connection hole in the middle provides a rigid connection to the drone fuselage, a bolt connection hole at the upper end provides a rigid connection to the drone's power output component, and a bolt connection hole at the lower end is used for fastening to the fuselage structure. It includes a groove-embedded component, which is rigidly connected to the main structure through the bolt connection hole to achieve precise fitting and positioning. This utility model effectively bears and counteracts the torsional torque generated during the operation of the power output component, significantly improving the stability of the power system and the torsional strength of the fuselage structure of large cargo drones under heavy-load conditions. It features high positioning accuracy, strong connection reliability, and excellent torsional performance, and is suitable for the power transmission systems of various large cargo drones.
