A highly stable detachable arm for a multi-rotor UAV

Abstract

The invention relates to a highly stable detachable arm for a multi-rotor unmanned aerial vehicle, comprising an arm, a mounting mechanism and a detachable connection mechanism, the mounting mechanism includes a fixing plate and a mounting piece, and the center of the fixing plate A plurality of line pins are installed throughout; the detachable connection mechanism includes a cylindrical fixing sleeve sleeved on the front end of the machine arm, and a corresponding cylindrical locking piece is sleeved on the machine arm, and the front of the cylindrical locking piece The side is locked and installed on the cylindrical mounting part of the mounting part through threaded connection; the front side of the cylindrical fixing sleeve is equipped with a pin fixing block, and corresponding line pins are movably installed on the pin fixing block; the cylindrical mounting The front side of the part is provided with a limit groove, and a limit washer is sleeved in the limit groove, and the outer edge of the limit washer is clamped on the cylindrical locking member in a squeezed state. The invention can prevent loosening between the connection between the detachable connection mechanism and the machine arm, and can ensure that there is no deformation between the connecting end of the circuit pin and the circuit pin.

Description

Technical field[0001]The present invention relates to a polycyclic unmanned machine arm, and specifically means a high-conditionable detachable machine arm with a multi-rotorless drone.Background technique[0002]The rotor drone has a small size, light weight, low cost, flexible operation and high safety, which feature a plurality of propellers, controlling multiple propelles through multiple motors to achieve flight. Rotile drones are widely used in aerial photography, detection, search and rescue, resource exploration, agriculture and other fields. The multi-rotorless no one generally has a plurality of processes, and the plurality of propelles and corresponding drive motors are respectively applied to the outer ends of the respective proks, respectively. The traditional rotor unmanned machine arm and the body are generally used in a fixed installation. Since the fixed-installed rotor drone is inconvenient, most of the existing rotorless proofer is mostly adopted Foldable or detacha...

AI Technical Summary

Problems solved by technology

There are two technical problems brought by the high-frequency vibration to the detachable arm: 1) cause looseness between the joint between the detachable connection mechanism and the machine arm, resulting in vibration between the detachable connection mechanism and the machine arm. The intensified formation between the connections is transmitted to the fuselage of the drone, which leads to a decrease in the operating stability of the drone; 2) the connection between the line pins and the line pins is prone to deformation, which eventually leads to an unstable conduction connection , making it difficult to guarantee the stable flight of UAVs

The existing detachable arms for rotor drones still have the disadvantages of complex structure, expensive manufacturing and maintenance costs
