An anti-collision device for UAV based on non-Newtonian fluid

Abstract

The present invention relates to the technical field of unmanned aerial vehicles, and discloses a kind of anti-collision device for unmanned aerial vehicles based on non-Newtonian fluid, which comprises shell one and shell two. There is a spring, the internal movable connection of shell one is connected with gear one, the internal fixed connection of shell one is connected with shell three, the internal movable connection of shell three is connected with gear two, the external fixed connection of gear two is connected with connecting plate, and the external movable connection of connecting plate is connected with Non-Newtonian fluid; through the interaction between shell one, pressure plate, spring, gear one, shell three, gear two, connecting plate, and non-Newtonian fluid, the UAV can pass through the structure when it is collided with the outside world. The transmission enables the subsequent anti-collision device to be activated, and the transmission between gear 1 and gear 2 can make the non-Newtonian fluid receive a greater external force, such triggering is more sensitive, which is more suitable for actual conditions.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a non-Newtonian fluid-based anti-collision device for drones. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. [0003] Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; the current applications in the fields of aerial photography, agriculture, plant protection, miniature selfies, etc. have greatly expanded the use of drones themselves, and develo...

AI Technical Summary

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
