Rotor wing protection structure for unmanned aerial vehicle

Abstract

The invention discloses a rotor wing protection structure for an unmanned aerial vehicle. The structure comprises an unmanned aerial vehicle body and four sets of supporting arms, the four sets of supporting arms are arranged at the four corners of the outer side of the unmanned aerial vehicle body, driving motors and rotors are arranged at the ends, away from the unmanned aerial vehicle body, ofthe four sets of supporting arms, protection assemblies are arranged on the outer sides of the rotors, and limiting assemblies for supporting the protection assemblies to rotate are arranged on the outer sides of the driving motors. Beneficial effects are that: the protection assemblies capable of contracting inwards are arranged outside the rotor wing of the unmanned aerial vehicle; the supporting rods are pushed to move through the three sets of arc-shaped protection plates which are separated from one another, so that collision energy is buffered through the compression springs, the protection assemblies are stressed to rotate relative to the unmanned aerial vehicle body in the collision process, the collision stability of the rotor wing is improved by transferring the contact collisionpoint of the unmanned aerial vehicle and the outside, and the protection effect is better.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a rotor protection structure for an unmanned aerial vehicle. Background technique [0002] From aerial photography to express delivery, from sky-showing skills to fire-fighting patrols, from ultra-low-altitude selfies to spraying pesticides, in recent years, drones have played an important role in our daily life and industrial production due to their easy deployment, safety, and convenience. With an increasingly important role, civilian drones are mainly divided into two categories: consumer-grade for the public and industrial-grade for industrial production. Consumer-grade products can meet people's entertainment needs, such as aerial photography, follow-up photography, etc.; industrial-grade products are suitable for line inspection, fire protection, disaster relief, etc., and the product types are diversified. The rotor position of the UAV usually needs to be provided ...

AI Technical Summary

Problems solved by technology

[0003] The applicant found that there are at least the following technical problems in the prior art: the currently used UAV rotor protection structure is an integrated ring structure, and when the UAV rotor position touches the external structure, the protection structure cannot provide effective buffering. As a result, the structure of the equipment is easily damaged under impact, which affects the flight dynamics of the UAV, and even causes the UAV to fall
