Anti-crash propeller with automatic energy storage rotation for unmanned aerial vehicle and method

Abstract

The invention discloses an anti-crash propeller with an automatic energy storage rotation function for an unmanned aerial vehicle and a method, belongs to the technical field of unmanned aerial vehicles, and aims to solve the problems that although an unmanned aerial vehicle in the prior art has an avoidance function, the unmanned aerial vehicle in a low-altitude state is easily attacked by flying birds, and children or curiosity people on the ground hit the unmanned aerial vehicle to cause damage to the unmanned aerial vehicle. When the unmanned aerial vehicle has a quality problem, the working state of the unmanned aerial vehicle is abnormal, and the unmanned aerial vehicle falls to the ground; the initial state of the parafoil is that the parafoil is arranged at the lower end of the unmanned aerial vehicle, the parafoil and the solar cell panel receive solar energy and do not interfere with each other, and when the unmanned aerial vehicle is in danger, the parafoil immediately protects the unmanned aerial vehicle to prevent the unmanned aerial vehicle from directly hitting the ground and protect propellers, and an operator can conveniently check fault reasons; the sliding strip plate impacts the movable inner rod, and the sliding rod is matched to drive the ejection ball to impact the parafoil cloth, so that the parafoil is quickly dispersed and unfolded, and the unfolding time of the parafoil is shortened.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-crash propeller with automatic energy storage and rotation for unmanned aerial vehicles and a method thereof. Background technique [0002] Unmanned aircraft is referred to as unmanned aerial vehicle. It is an unmanned aircraft that is operated by radio remote control equipment and self-provided program control devices, or is operated completely or intermittently by an on-board computer. According to the application field, unmanned aerial vehicles can be divided into For military and civilian use, in terms of military use, UAVs are divided into reconnaissance aircraft and target drones. In civilian use, UAVs are the real just-needs for aerial photography, agriculture, plant protection, miniature selfies, express transportation, disaster rescue, wildlife observation, The application of monitoring infectious diseases, surveying and mapping, news reporting, ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an anti-crash propeller with automatic energy storage and rotation for unmanned aerial vehicles and its method, which solves the problem that the existing unmanned aerial vehicle in the background technology keeps it in a working state by storing electricity, but during the flight, the operator cannot If it is charged, the endurance effect is poor. When the battery is low, the flight of the UAV has to be interrupted. Although the UAV in the prior art has an avoidance function, the UAV in the low-altitude state is easily attacked by birds. , and children or curious people on the ground will smash the drone, causing the drone to be violently disturbed by the outside world, and when the drone has quality problems, its working state will be abnormal, and it will fall to the ground. Due to structural reasons, the damage to the propeller is the largest, and it will be scrapped directly when it is serious. Moreover, due to the collision between the drone and the ground, the operator cannot judge the cause of the drone's failure, it is not easy to repair, and the service life is limited.
