Unmanned aerial vehicle with protection device based on chassis

Abstract

The invention discloses an unmanned aerial vehicle with a protection device based on a chassis. The unmanned aerial vehicle with the protection device based on the chassis comprises a camera, foot stools, turbines, propellers, a UAV body, and the protection device; an upper end of the camera is fixedly arranged at a bottom surface of the UAV body, and the camera is arranged at the lower side of the protection device; two foot stools are arranged at the lower side of the UAV body, four turbines are equidistantly arranged at four sides of the UAV body, eight paddlers are fixedly arranged at theupper side of the turbines by taking two paddlers as a group, and the protection device is arranged at a bottom end of the UAV body. Since the bottom chassis design of the multi-rotor unmanned aerialvehicle is low, the reactive force produced by the foot stools when contacting the ground can enable the foot stools and the chassis to contact to produce the friction; one protection device can be added on the chassis of the unmanned aerial vehicle, thereby effectively maintaining the connection between the foot stools and the unmanned aerial vehicle chassis under the buffer and protection effect, and the abrasion on the surface is minimally reduced.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a protection device based on a chassis. Background technique [0002] In the field of aerial photography, in order not to be affected by the wind and to maintain a stable attitude in flight, nowadays, multi-rotor UAVs are mostly used for aerial photography. The main multi-rotor UAVs have simple operating principles and high reliability. [0003] In the design of multi-rotor UAV, the distance from the ground of the rotor disc is relatively low, resulting in a large load pressure on the disc under the same tension. The installation and connection of the chassis of the machine will cause different degrees of extrusion. If you do this many times, it will easily damage the chassis and tripod. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies in the prior art, the present invention provides a ...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a UAV with a protection device based on the chassis to solve the problem that the existing multi-rotor UAV has a low ground clearance in the design of the rotor disc, which results in the same Under tension, the paddle disc load pressure will be very large. Under tension, because the tripod touches the ground first, the tripod will be squeezed to some extent on the installation and connection with the chassis of the drone. If you do this many times, it will It is easy to cause damage to the chassis and tripod
