Multifunctional unmanned aerial vehicle undercarriage

Abstract

The invention relates to the field of unmanned aerial vehicles, in particular to a multifunctional unmanned aerial vehicle undercarriage which comprises a connecting disk and two first landing gears.The two first landing gears are symmetrically arranged at the bottom of the connecting disk, a second landing gear is further arranged at the bottom of the connecting disk, the second landing gear andthe two first landing gears are distributed in an isosceles triangle form and are three vertexes of an isosceles triangle, a driving device for driving the two first landing gears and the second landing gear to synchronously fold or unfold is arranged on the connecting disk, and the periphery of the top of the connecting disk is connected with the bottom of an unmanned aerial vehicle body througha plurality of connecting supports. In the rising or landing process of an unmanned aerial vehicle, a first inclined arm and a second inclined arm can be flexibly adjusted to guide and support the unmanned aerial vehicle in the landing process, comprehensive irradiation of a camera on the lower portion of the unmanned aerial vehicle in flight is met, and wings can be protected from impact damagein flight.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a multifunctional landing gear for unmanned aerial vehicles. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control telemetry equipment and its own program control device. UAVs can be divided into many categories, one of which is multi-rotor UAV, which can also be called multi-axis UAV. According to the number of propellers, it can be subdivided into four-rotor, six-rotor, octa-rotor, etc. It is generally believed that the more the number of propellers, the smoother the flight and the easier the operation. Multi-rotor drones are widely used in aerial remote sensing, meteorological research, agricultural aerial seeding, and pest control. There will be an information collection camera under the fuselage; the landing gear of traditional multi-rotor drones is fixedly connected to the fuselage Together...

AI Technical Summary

Problems solved by technology

Multi-rotor drones are widely used in aerial remote sensing, meteorological research, agricultural aerial seeding, and pest control. There will be an information collection camera under the fuselage; the landing gear of traditional multi-rotor drones is fixedly connected to the fuselage Together, they cannot move. In daily flight work, the traditional landing gear will make the exposure range of the acquisition camera not large enough, and due to the unskilled operation of some ground-facing UAV operators, when the UAV performs When falling, the front of the fuselage will tilt forward. After the fuselage falls completely, there will be friction with the ground during the period, which will greatly shorten the use time of the drone over time.
