Description

A prefabricated drone

The present invention relates to a prefabricated drone, and more particularly, to a prefabricated drone that is provided with a plurality of components constituting the drone and can be easily assembled even by children or beginners.

'Drone' refers to an airplane or helicopter-shaped aircraft that flies by induction of radio waves without a human being on board, and is mainly used for military purposes such as targeting, reconnaissance, and surveillance, but recently It is also used for various purposes. That is, it is an unmanned courier service for internet shopping malls or taking pictures of places that are difficult for a person to go and film, such as taking pictures of a volcanic crater. In the case of an unmanned delivery service, documents, books, pizza, etc. are delivered to individuals using GPS (Global Navigation System) technology that uses artificial satellites to determine location. In addition, recently, the field of application of drones is gradually expanding, such as a helicam that captures images while remotely controlling a drone by attaching a camera to the drone, which is widely used for broadcasting.

As drones are closely introduced into real life, the use of drones as toys for educational purposes is increasing. In order to use drones for educational purposes, they should be developed to be easy for general users to assemble, that is, drones formed by combining a number of parts are being developed to enhance creativity.

Accordingly, the demand of people who want to learn drones is increasing. However, in this case, when practicing indoors, since the control is not mastered, the drone bumps into a wall or collides with a person, causing a safety accident. In order to solve this problem, even if practiced outdoors, there was a problem in which learning efficiency was reduced, such as drones falling to the ground and being damaged or drones colliding with each other.

In addition, existing drones are made of a combination of parts formed of plastic or metal injection molding, and since the weight of the drone body is heavy, there is a risk of accidents when operating by ordinary people, and there is a problem that is difficult for beginners to handle.

Accordingly, development of prefabricated drones for toys that can be easily assembled even by children, is not injured even when colliding with a person, and can prevent damage to the main body of the drone is being actively developed.

As described above, the first coupling portions 201c and 201d formed on the first side frame 220 and the second coupling portions 301b and 301c formed on the second side frame 320 of the vertical guard unit 300 are It is formed in the center of the first side frame 220 and the second side frame 320, and since it is formed at the same height, the horizontal guard part 400 does not bend and the main body guard part 200 and the vertical guard part 300 can be combined

The first coupling portions 201c and 201d formed on the first side frame 220 of the body guard unit 200 and the second coupling portions 301b and 301c formed on the second side frame 320 of the vertical guard unit 300 ) In addition, 'L'-shaped first separation prevention units 202c and 202d and second separation prevention units 302a and 302b are formed. This is provided to prevent the respective guard parts from departing from each other when the drone 10 is assembled by combining the body guard part 200, the vertical guard part 300, and the horizontal guard part 400.

The outer surface of the frame constituting the body guard part 200, the vertical guard part 300 and the horizontal guard part 400 constituting the drone 10 of the present invention is the body guard part, the vertical guard part and the horizontal guard The outer surface of the frame constituting one or more selected parts is continuously arranged with embossed protrusions formed in a curved surface, so that even if the drone 10 collides with a person, a person is injured by the embossed protrusion formed on the outer surface of the frame. can be prevented, and even if it collides with another object or wall, since the guard can absorb the impact, damage to the drone 10 can be minimized and wind resistance can be reduced.

10 illustrates a perspective view of a coupling part of a prefabricated drone according to an embodiment of the present invention. As shown in FIG. 10, the second coupling formed on the second upper frame 330 of the vertical guard 300 is coupled to the first coupling portion 201a formed on the first upper frame 230 of the body guard 200. Part 301a is fitted. This is for explaining one example, the first coupling portion 201e formed on the first lower frame 210 of the main body guard unit 200 is formed on the second lower frame 310 of the vertical guard unit 300. It is fitted into the second coupling portion 301d and is horizontal to the first coupling portions 201c and 201d or the second coupling portions 301b and 301c formed on the first side frame 220 and the second side frame 320. The same applies when the third coupling parts 401a, 401b, 401c, 401d, 401e, and 401f of the guard part 400 are fitted.

One end of the first coupling part 201a is blocked by the 'L'-shaped first separation preventing part 202a. As described above, the body guard unit 200, the vertical guard unit 300 and the horizontal guard unit 400 of the present invention are formed of a material having a predetermined elasticity. Therefore, by applying an external force to the first separation preventing portion 202a blocking one end of the first coupling portion 201a, the first separation preventing portion 202a blocking the first coupling portion 201a is moved to achieve the first engagement. The second coupling portion 301a of the second upper frame 330 can be coupled to the portion 201a, and after the second coupling portion 301a is fitted to the first coupling portion 210a, the first coupling portion 301a is fitted. When the external force applied to the separation prevention unit 202a is removed, the first separation prevention unit 202a returns to its original position by elasticity and blocks one end of the first coupling unit 201a again, so that the vertical guard unit 300 is the main body. It is prevented from being separated from the guard part 200.

More specifically, by applying an external force to the first separation preventing portion 202a blocking one end of the first coupling portion 201a formed by digging a predetermined depth into the upper surface of the first upper frame 230, the first coupling portion 201a After one end of ) is opened, the second upper frame 330 is inserted into the first coupling part 201a. At this time, the second upper frame 330 is vertically coupled to the first upper frame 230, and the second coupling part 301a formed on the lower surface of the second upper frame 330 has the first upper frame 230 is inserted Accordingly, the first upper frame 230 and the second upper frame 330 are coupled in a form in which parts are inserted into each other by the first coupling portion 201a and the second coupling portion 301a. After the first upper frame 230 and the second upper frame 330 are coupled, when the external force applied to the first separation prevention unit 202a is removed, the first separation prevention unit 202a returns to its original position and the first separation prevention unit 202a returns to its original position. Since the upper end of the coupling part 201a is blocked, it is possible to prevent the second upper frame 330 from being separated from the first upper frame 230 .

Therefore, since the drone 10 of the present invention can be manufactured by assembling the ring-shaped main body guard unit 200, the vertical guard unit 300, and the horizontal guard unit 400, assembly is easy and even children or beginners can easily assemble it. In addition, it is possible to provide a drone 10 that is easy to assemble and at the same time maintains close coupling between each guard unit.

Technical ideas should not be interpreted as being limited to the above-described embodiments of the present invention. Not only the scope of application is diverse, but also various modifications and implementations are possible at the level of those skilled in the art without departing from the gist of the present invention claimed in the claims. Therefore, such improvements and changes fall within the protection scope of the present invention as long as they are obvious to those skilled in the art.
