Telescopic propeller arm component and unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle and a telescopic propeller arm component. The unmanned aerial vehicle comprises a machine body and telescopic propeller arm components; each telescopic propeller arm component is arranged on the outer side of the machine body and comprises a first propeller arm, a second propeller arm, a gear and a rack; each first propeller arm is fixedly connected with the corresponding gear; each second propeller arm is fixedly connected with the corresponding rack; and each gear is meshed with the corresponding rack, and each second propeller arm stretches relative to the corresponding first propeller arm through the corresponding rack when the gear rotates. With adoption of the unmanned aerial vehicle, the length of propeller arms can be regulated according to the use requirements to be matched with screw propellers in different specifications, so that different power efficacies are formed so as to meet different application needs.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a retractable paddle arm assembly and an unmanned aerial vehicle. Background technique [0002] At present, most of the paddle arms of UAVs are fixed, which leads to the large size and poor portability of UAVs. Moreover, in actual operation, the blades of the UAV are of fixed size, and the pitch of the blades cannot be adjusted. When heavy-load operation is required or the requirements for battery life are high, the operating power consumption will be too large due to insufficient blade specifications, which will affect the performance of the drone. Contents of the invention [0003] The object of the present invention is to provide a retractable paddle arm assembly and an unmanned aerial vehicle whose paddle arms can be stretched and the pitch can be adjusted according to requirements. [0004] A retractable paddle arm assembly, including a first paddle arm, a second ...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the paddle arms of drones are fixed, resulting in large volume and poor portability of drones

Moreover, in actual operation, the blades of the UAV are of fixed size, so the pitch of the blades cannot be adjusted

When heavy-load operation is required or the requirements for battery life are high, the operating power consumption will be too large due to insufficient blade specifications, which will affect the performance of the UAV.
