AI Technical Summary

Technical Problem

When multi-rotor drones are disturbed by airflow in complex environments, their attitude becomes unstable, making it difficult to maintain a stable hovering state or a precise flight trajectory, which affects the equipment's working accuracy and safety.

Method used

It adopts an automatic balance adjustment structure and a buffer structure, and uses a combination of fixed magnetic rings and movable magnetic rings to adjust the counterweight seat through an electric slide and an electric lifting rod. Combined with buffer springs and rubber buffer plates, it absorbs the impact force, and the gyroscope provides real-time attitude data feedback to correct attitude deviations.

Benefits of technology

It improves the flight stability of multi-rotor UAVs in complex environments, reduces the impact of airflow interference on the airframe, ensures the stability of hovering and flight trajectory, and enhances the working accuracy and safety of the equipment.

Abstract

This utility model relates to an automatic balancing bracket for multi-rotor drones in flight, belonging to the field of multi-rotor drone flight technology. It includes a drone flight shell, with an automatic balancing adjustment structure and a buffer structure at the bottom of the flight shell. The automatic balancing adjustment structure includes two support legs fixedly connected to the bottom of the drone flight shell, with fixed magnetic rings fixedly connected to the outer periphery of each support leg. This automatic balancing bracket for multi-rotor drones in flight uses the cooperation of fixed and movable magnetic rings to attract a counterweight. An electric slide and an electric lifting rod drive a pressure plate to move left and right and up and down, pressing the counterweight downwards on the side requiring balancing, thereby reducing the impact of airflow on the multi-rotor drone. The buffer component reduces the impact force when the fixed and movable magnetic rings attract each other.
