Problems solved by technology

[0002] A lot of propellers will be installed on the upper end of the main unit of the multi-rotor UAV. In order to prevent the propellers from being damaged by impact during flight, we will add protective brackets outside the propellers. Due to the large number of propellers, the number of protective brackets will also be corresponding. increase, and the use of such a large number of propellers will inevitably increase the overall weight of the UAV and reduce the endurance
In addition, the drone also needs to be equipped with landing gear to support the use of the drone, and the setting of the landing gear also increases the overall weight of the drone, and the landing gear will cause certain resistance to the flight of the drone

Abstract

The invention discloses a movable landing gear of a multi-rotor unmanned aerial vehicle, comprising an unmanned aerial vehicle (UAV) main engine and four propellers arranged on the top of the UAV mainengine, an elastic airbag is adhered and fixed at the middle of the bottom of the UAV main engine, an air inlet and an air outlet hole are arranged at any position of the elastic airbag, and two connecting rods are respectively installed on two sides of the elastic airbag; the bottom of the connecting rod is provided with a rotating cavity, a supporting foot frame is installed in the rotating cavity between two adjacent connecting rods, and the top of both ends of the supporting foot frame is rotatably installed in the rotating cavity. The unmanned aerial vehicle (UAV) of the invention uses the landing gear as the support and the protection, can use the bulging elastic airbag as the cushion for landing, saves the structure of the propeller protection bracket, reduces the overall weight ofthe UAV, does not use any electronic equipment, and does not increase the weight of the UAV.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a movable landing gear of a multi-rotor unmanned aerial vehicle. Background technique [0002] A lot of propellers will be installed on the upper end of the main unit of the multi-rotor UAV. In order to prevent the propellers from being damaged by impact during flight, we will add protective brackets outside the propellers. Due to the large number of propellers, the number of protective brackets will also be corresponding. The use of such a large number of propellers will inevitably increase the overall weight of the UAV and reduce the endurance. In addition, the drone also needs to be equipped with a landing gear to support the use of the drone, and the setting of the landing gear also increases the overall weight of the drone, and the landing gear will cause certain resistance to the flight of the drone. Contents of the invention [0003] The technical problem to be s...
