Retractable Paddle Arm Assembly and UAV

Abstract

The invention provides an unmanned aerial vehicle and a retractable paddle arm assembly. An unmanned aerial vehicle includes a fuselage and a retractable paddle arm assembly. The retractable paddle arm assembly is arranged on the outer side of the fuselage. The retractable paddle arm assembly includes a first paddle arm, a second paddle arm, a gear and a rack. The first paddle arm is fixedly connected with the gear, and the second paddle arm is fixedly connected with the rack. The gear is engaged with the rack, and when the gear rotates, the second paddle arm is stretched relative to the first paddle arm through the rack. The above-mentioned UAV can adjust the length of the paddle arm and match the propellers of different specifications according to the needs of use, so as to form different force effects to meet different application requirements.

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 ...

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.
