Unmanned aerial vehicle anti-collision device based on non-Newtonian fluid

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle anti-collision device based on the non-Newtonian fluid. The device comprises a firstshell and a second shell, a pressing plate is movably connected to the interior of the first shell, a spring is movably connected to the exterior of the pressing plate, a first gear is movably connected to the interior of the first shell, a third shell is fixedly connected to the interior of the first shell, a second gear is movably connected to the interior of the third shell, a connecting plateis fixedly connected to the exterior of the second gear, and non-Newtonian fluid is movably connected to the exterior of the connecting plate; under the interaction of the first shell, the pressing plate, the spring, the first gear, the third shell, the second gear, the connecting plate and the non-Newtonian fluid, when the unmanned aerial vehicle is subjected to external collision, the subsequentanti-collision device can be started through transmission between structures, non-Newtonian fluid can be subjected to larger external acting force through transmission between the first gear and thesecond gear, triggering is more sensitive, and the anti-collision device is more suitable for being used in actual conditions.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a non-Newtonian fluid-based anti-collision device for unmanned aerial vehicles. Background technique [0002] Unmanned aircraft is abbreviated as "unmanned aerial vehicle", which is an unmanned aircraft that uses radio remote control equipment and self-provided program control devices, or is completely or intermittently operated by an onboard computer. [0003] Compared with manned aircraft, drones are often more suitable for tasks that are too "dumb, dirty, or dangerous." According to application fields, UAVs can be divided into military and civilian use. For military purposes, UAVs are divided into reconnaissance aircraft and target aircraft. For civilian use, drones + industry applications are the real rigid needs of drones; current applications in the fields of aerial photography, agriculture, plant protection, micro selfies, etc. have greatly expanded the use of ...

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a UAV anti-collision device based on non-Newtonian fluid, which has the advantages of air pressure anti-collision and sensitive triggering, and solves the problem that the UAV needs to be manually operated by the operator. There are collisions of drones caused by improper human control or external environmental factors. Although drones are equipped with anti-collision frames today, due to the quality control of drones, the anti-collision frames will be made of lighter materials. The anti-collision effect will not be too obvious, and the UAV is a relatively sophisticated machine, so the UAV after the collision is very likely to cause damage to its parts
