Description

Drone with stable motion and degree of freedom {A DRONE}

The present invention relates to a drone having a device unit, and to be more specific, when the flight unit and the device unit are operated separately from each other and are in flight, the flight unit is free from the device unit and can fly easily with a balance, and vice versa. It relates to a drone that is stably operated with minimal interference from the flight unit when additional operation is in progress.

In general, a drone is a generic term for an unmanned aerial vehicle (UAV) in the shape of an airplane or helicopter that can be flown and controlled by radio wave guidance without a pilot.

In the past, it was used for military purposes, but recently it has been transferred to the private sector and applied to various fields.

For example, a service that installs a camera at the bottom of the drone body to easily access and shoot places that are difficult for humans to move directly, or a courier service that delivers specific items using gripping means such as GPS (Satellite Navigation System) and clips , or a control service that sprays extinguishing fluid, or a service that displays specific information in the air by the afterimage effect while the LED emits light according to the rotation speed of the mounting frame.

However, these drones have a problem that, while configuring a separate device unit in the body of the flight unit, the flight unit is affected by the unit having a considerable volume and weight, making it unstable or difficult to balance.

In particular, when the device unit is in operation, there is a problem that sometimes unstable operation is made due to the interference of the flight unit. That is, there are many cases in which the body tilts or shakes due to wind, turbulence, or other reasons in the air due to a difference in air pressure or temperature, etc. In this case, there is a problem that the device part is tilted together with the flight part and operates abnormally.

For a simple example, if the flight part is tilted to balance, the camera is also tilted to take pictures of shaking images or wrong spots, and during delivery, the contents in the box are tilted and damaged, and information is being displayed. At that time, there was a problem in that the tilted image could not but be displayed inaccurately.

Hereinafter, each configuration will be described in more detail as follows. First, the drone 1 according to an embodiment of the present invention includes a flight unit 3 , a device unit 2 , and a connection unit 10 .

At this time, the flight unit 3 forms a plurality of legs 6 extending outside the body 4 in which the through-hole 5 is formed, and a propeller 7 is formed on each leg 6 to be able to fly. it is well composed.

In addition, the device unit 2 is a device installed outside the flight unit 1 to provide a specific service,

Typically, in the display device 30, in a state in which the mounting frames 30b in which the plurality of LEDs 30a are formed are connected to the first coupler 30c and the second coupler 30d located at the upper and lower portions, the first The rotation shaft 30e and the pillar 14 provided in the coupler 30c and the second coupler 30d are rotatably connected to the fixed body 20, and each LED 30a rotates the mounting frame 30b. This is to express specific information by the afterimage effect while emitting light according to the speed. In addition, according to an embodiment, the device unit 2 may be a camera 31 that captures a surrounding image by approaching a place where it is difficult for a person to directly move, or a holding means 32 that fixes a specific item to transport it. Also, it is preferable to be installed at the lower end or upper end of the column 14 according to the embodiment, but according to the embodiment, it may be installed in the left, right, or diagonal direction according to the position of the column.

In addition, the connection part 10 connects the flight part 3 or the device part 2 to be swingable in the vertical direction or in the left and right directions, and in particular, it can swing within a certain range by a ball joint method or a link connection method. can be combined, but

As shown in Figures 2 and 3, the connecting portion 10 is preferably connected by a shaft coupling method.

That is, the connection part 10 forms a through hole 5 through-hole in the vertical direction in the center of the body 4, and the through-hole 5 is spaced apart at a predetermined interval inside the through-hole 5. ) projecting outward to form a pillar 14, and the pillar 14 has an assembly tool 11 that is axially coupled to the body 4 of the flying part 3 so as to be swingable in the vertical direction and swingable in the left and right directions. By installing, the flight unit 3 and the device unit 2 are configured to be separated and operated according to each other. this

At this time, the pillars are preferably installed in the vertical direction, but may be installed to be balanced in the left and right or diagonal directions depending on the embodiment, but is not limited thereto.
