Abstract

The invention relates to a foldable drone. The foldable drone comprises a drone body, wherein the drone body is provided with a plurality of propeller arms symmetrically distributed relative to the symmetrical plane in the drone body, one end of each propeller arm is provided with a propeller blade component, a central shaft is connected to the central positon of the bottom of the drone body, a circular ring which can slide up and down along the central shaft sleeves the central shaft, a framework is hinged to the outer side of the circular ring through a hinge, the other ends of the framework are hinged to the middles of the propeller arms through hinges, a fixing device is arranged on one side of the central shaft, a landing gear is connected to the other end, connected with the drone body, of the central shaft, and the bottom of the landing gear is provided with damping feet. The foldable drone has the advantages that the propeller arms can be retracted along with a motor and propeller blades during transporting and carrying, space occupation is reduced, and the propeller arms and the propeller blades are favorably protected from being damaged easily during the transporting and carrying.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a foldable unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle (UAV) is a kind of aircraft that is gradually becoming practical at present. It has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. Loading multiple types of sensors on UAVs, such as cameras, can realize real-time image transmission and detection of high-risk areas. monitor. At present, most UAVs are designed and manufactured based on the flight principle of helicopters, which can realize vertical lift and high-altitude hovering, so as to meet the requirements of aerial photography and monitoring. The most common ones are single-axis single-propeller, single-axis common propeller and multi-rotor (e.g. quadrotor) form. [0003] There are many types of drones at present, but there is a problem that the paddle arms and blades ar...
