Description

[0001] DROND HAVING ROTOR PROTECTION FUNCTION [0002]

The present invention relates to drone, and more particularly, to a drone having a structure that protects a rotor of a drone from an external impact and prevents a human injury or damage to a facility by a rotor.

The drone is a unmanned aerial vehicle capable of remote control and automatic flight, basically shaped like an airplane or a helicopter.

The drones, such as helicopters, which generate lift and propulsive force by rotating the rotor, are classified into a quad-copter with four rotors, a hexacopter with six rotors, and an octocopter with eight rotors, and is collectively referred to as a multi-copter.

The multi-copter type drones have a large number of rotors and a relatively high output corresponding to the number of rotors, which makes it possible to stabilize hovering even when the airframe is heavy and to use various flight motions. In recent years, such a multi-copter type drone has been widely used for general leisure.

However, the drones may collide with people or facilities during a flight and cause damage. Particularly, a rotor rotating at a high speed is required to be exposed to the air. In addition to damaging a person, the wing is damaged by an external impact, There is a vulnerability that could lead to a crash.

Patent Document 1 discloses a protective cover for an unmanned aerial vehicle having an upper end protector and a lower end protector in which a vent is formed at a position corresponding to a position of a rotor in relation to a rotor protection technology of a drone.

However, such a protective cover is difficult to be applied to existing drones of various designs in a compatible manner, and has a disadvantage that the weight of the gas significantly increases.

Further, it is difficult to protect the rotor in all directions, and for example, there is a weak point that when the external impact is applied from above and below the rotor, the rotor may be easily damaged.

Alternatively, recently, a technique has been proposed in which the entire outer surface of the dron is covered with a single protection net to protect it from external impacts. However, when the entire dron is wrapped in a protective net, it is difficult to secure a space for mounting additional equipment such as a camera or an ultrasonic sensor, and the design of the dron is limited. In addition, since it is difficult to symmetrically produce a portion contacting the ground, there is a disadvantage in that the landing and landing of the dron can not be performed stably.
