The self-locking unmanned aerial vehicle articulated arm at least comprises a longitudinal middle shaft, a detachable side arm, movable side arms and radial lock bodies, the movable side arms comprise hollow shell-shaped middle shells, and further comprise external lantern rings, internal mandrels and side arm bodies,the radial lock bodies comprise input assemblies, cone pulley assemblies, worm assemblies, worm gear assemblies and elastic lock cylinders, and the self-locking unmanned aerial vehicle articulated armfurther comprises axial lock bodies, telescopic lock heads and adjusting assemblies.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a self-locking articulated arm of an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device; compared with manned aircraft, it has small size, low cost, easy to use, low requirements for combat environment, and battlefield survivability. Strong and other advantages. Most UAVs use an integral mechanism, and the integral UAV takes up a lot of space, which is not conducive to the miniaturization design of the UAV, and the integral UAV limits the adjustment angle of the arm, so it is necessary to Man-machine folding arm. [0003] The patent of authorized notification number CN110789704B discloses a UAV folding arm, including a main arm and an auxiliary arm, which realizes the folding between the main arm and the auxiliary arm through a limit ...

AI Technical Summary

Problems solved by technology

However, the two-arm structure means that it is difficult for the UAV to achieve dynamic balance, so it is necessary to involve a UAV articulated arm that can be folded and locked in the three-arm state
