Vehicle arm retraction type UAV (unmanned aerial vehicle) capable of winding cable

Abstract

The invention belongs to the technical field of UAVs (unmanned aerial vehicles) and particularly relates to a vehicle arm retraction type UAV capable of winding a cable. The UAV comprises a vehicle body, wherein two vehicle arms are mounted on the vehicle body and are symmetrically distributed on the vehicle body; two power components capable of providing lifting force are symmetrically distributed in each of the vehicle arms, and the vehicle body is provided with a required part capable of driving the power components to work; each of the vehicle arms is provided with a main vehicle arm and telescopic arms arranged on the two sides of the main vehicle arm and capable of being telescopic in telescopic cavities symmetrically distributed in the vehicle arm, and each of the power components is mounted on the upper side, far away from one end of the vehicle body, of the corresponding telescopic arm; a winding disk is mounted in a cavity of each of the main vehicle arms, and the cable for driving each of the power components passes the vehicle body and a central cavity, the middle part of the cable is wound on the winding disk, enters into one of the telescopic cavities and is connectedwith the corresponding power component; through the design of the winding disk, in a process that the telescopic arms retract into the telescopic cavities, a winding mechanism is driven by a third rack mounted on one of the two telescopic arms of the same main vehicle arm, so that the loosened cables can be wound on the winding disks by the winding mechanism, therefore, the internal cables cannotbe squeezed.

Description

Technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an arm retractable unmanned aerial vehicle capable of winding wires. Background technique [0002] At present, in order to solve the problem that the four arms plus the propellers occupy a large space during the transportation of the four-rotor UAV, the design of the arms has a telescopic arm that can be extended, which reduces the transportation space to a certain extent and increases the transportation efficiency. However, when the telescopic arm is telescopic in the telescopic cavity, the wires of the driving motor in the telescopic cavity will loosen, so that there will be spatial interference with the telescopic arm in the telescopic cavity, and even the problem of the telescopic arm squeezing the wires. [0003] The present invention designs a retractable drone arm capable of winding wires to solve the above problems. Summary of the invention [0004] ...

AI Technical Summary

Problems solved by technology

However, when the telescopic arm expands and contracts in the telescopic cavity, the wires of the drive motor in the telescopic cavity will loosen, so that there will be spatial interference with the telescopic arm stretching and contracting in the telescopic cavity, and even the problem that the telescopic arm will squeeze the wires will occur.
