Description

Easy-to-move drones{Drone}

The present invention relates to a drone that is easy to move, and more particularly, when a drone with a certain weight or more is moved on land, a wheel provided on a skid is used, a handle is used on an arm connected to the drone body, or a skid The present invention relates to a drone that is easy to move by using a handle protruding from one end so that a user can easily move while holding the handle on land.

In general, drones (commonly referred to as “multicopters”) using multiple blades or propellers were first developed for military purposes, but due to their convenience in transportation, storage and operation, they have recently been developed as a device for spraying pesticides, making them suitable for large-scale farming. It is currently in wide use.

A drone, a conventional unmanned aerial vehicle, includes a drone body, arms protruding radially from the outer circumference of the drone body, wing modules detachably installed at the ends of the arms, and extending downward from both sides of the lower end of the drone body. A pair of supports and a pair of skids having a predetermined length along the horizontal direction at the bottom of each of the pair of supports.

However, conventionally, if the drone has a small size below a certain level, there is no problem in moving it on land, but if it has a heavy and large body above a certain level, when the drone is moved on land, it is carried by several people or moved to another moving body. There is a problem with not being able to move easily.

In addition, it is preferable that a gyro sensor 110 is installed on the drone main body 100 to control the drone to keep it level when flying.

You cannot unload the drone from the vehicle and fly right next to the vehicle. There is a safe distance from people, so you have to move.

However, if the weight is light during movement, it can be moved by one person, but in the case of a large drone, the back may be burdened. Therefore, when getting off, two people are required to move, and two people must lift the medicine when moving to another place after putting the medicine in the medicine chest. However, if the drone according to the present invention is applied, one person can sufficiently move the drone on land.

In addition, although not shown in the drawings, lifting modules having lifting rods that are lifted under the control of a controller may be disposed at multiple locations at the lower ends of the pair of skids.

Auxiliary wheels are further installed at the end of the elevating rod. Horizontal sensors are respectively installed on the pair of skids.

A pressure sensor for detecting pressure generated when the auxiliary wheels are seated on the ground is installed on the elevating rod.

When a pressure is sensed by the pressure sensor, the controller may variably adjust lifting positions of the auxiliary wheels using the lifting modules to receive a horizontal signal from the horizontal sensor.

In addition, when the operation of the first cylinders is recognized in a state in which the flight modules are operated during flight, the controller determines an abnormal state, returns the wheels to their original positions using the first cylinders, and returns the wheels to their original positions. In this case, a flight path may be forcibly modified to be forcibly moved to a position of a preset station, and the drone body may be controlled to forcibly return to the station by driving the flight modules.
