When the arm 1200 and the landing portion 1400 reach the folded folding position as shown in FIG. 8B, they are no longer folded. Accordingly, when the user holds or transports the unmanned aerial vehicle 1000 at the folding position, it is preferable to move the sliding adjustment handle 1737 to the sliding limit position so as to maintain the folding position.

The main body 2110, the propeller 2130, and the driving unit 2150 have the same or similar structures as those of the above-described example, and thus a detailed description thereof will be omitted.

The arm 2200 includes a first arm 2230 for supporting a center body 2110 and a driving unit 2150 extending from the first arm 2230 to drive the propeller 2130 and the propeller 2130 And a second arm 2250 coupled to the first arm 2230 by an arm hinge portion 2300 so as to be rotatable with respect to the first arm 2230.

The structure of the first arm 2230 and the second arm 2250 includes a rectangular pipe made of carbon in this embodiment, but may be modified into various structures such as a circular shape.

The arm hinge portion 2300 preferably includes an arm hinge pin 2330 and an arm clamp 2350.

As shown in FIGS. 10A and 10B, the arm clamp 2350 includes an unclamping position for releasing the mutual coupling so that the first arm 2230 and the second arm 2250 can rotate with respect to each other, And the first arm 2230 and the second arm 2250 are detachably coupled to each other.

The arm clamp 2350 includes a clamp body 2353 coupled to the first arm 2230 and having a linkage structure having an engagement member (not shown), and a clamp arm 2353 detachably coupled to the clamp body 2353 A clamping member 2357 provided on the second arm 2250 and a fixing pin (not shown) for fixing the clamping body 2353 coupled with the clamping member 2357 to the clamping position are coupled It is preferable to have a clamp fixing member 2355 coupled to the first arm 2230 with a fixed pinhole 2359. [

When the user clamps the clamp main body 2353 to the clamping member 2357 at the clamping position and then fixes the clamp main body 2353 with the fixing pin by turning the clamp main body 2353, 1 arm which can not be rotated with respect to the arm 2230 as shown in FIG.

On the other hand, when the user removes the fixing pin and unclamps the clamp main body 2353 from the clamp engaging member 2357 by tilting the clamp main body 2353, the second arm 2250 is disengaged from the first arm 2230 So that the second arm 2250 can be rotated about the first arm 2230 about the arm hinge pin 2330 as shown in FIG. 10B.

The landing link 2600 preferably includes a landing link pipe 2610, a landing link 1 hinge portion 2630, and a landing link 2 hinge portion 2650.

On the other hand, one side of the landing link 2600 is rotatably coupled to the first arm 2230, and the other side is rotatably coupled to the landing unit 2500. The landing link 2600 is coupled to the outside of the first arm 2230 and the landing part 2500 in a pair as shown in FIG. 11, so that the first arm 2230 and the landing part 2500 are landed And a landing link pipe 2610 that does not cause interference when the link 2600 overlaps. Thus, in the folded position, the first arm 2230 and the landing link 2600 may be located on a coaxial line. Between the landing link pipes 2610, a landing link bracket 2620 is preferably included which is in contact with the lower end of the first arm 2230 so as to be able to maintain its position on the coaxial line with the reinforcement or first arm 2230 Do.

The landing link pipe 2610 is rotatably coupled to the first arm 2230 by a landing link 1 hinge part 2630 and is rotatable by the landing part 2500 and the landing link 2 hinge part 2650. [ Respectively.

The landing part 2500 is rotatably coupled to the second arm 2250 by a landing hinge part 2700.

Here, the structure of the landing hinge portion 2700, the landing link 1 hinge portion 2630, the landing link 2 hinge portion 2650, and the arm hinge pin 2330 includes a rod shape having a bolt or pin shape, Since the structure is simply known in which the mutually coupled structures are rotatably coupled, a detailed description thereof will be omitted.

An unillustrated 2233 represents an arm leg extending partially downward from the first arm 2230.

The operation of the unmanned aerial vehicle 2000 according to another embodiment having such a configuration will be described in detail with reference to FIGS. 12A and 12B.

12A is a flight position in which the unmanned flying vehicle 2000 can fly. In this case, the second arm 2250 is a clamping position in which the rotation of the second arm 2250 is restricted with respect to the first arm 2230, The second arm 2250 is coupled to the first arm 2230 as shown in FIG.

When the user releases the arm clamp 2350 and places it in the unclamping position as shown in FIG. 10B, the second arm 2250 rotates with respect to the first arm 2230 while the second arm 2250 rotates with respect to the main body 1110 The landing link 2600 also moves toward the main body 1110 and rotates about the first arm 2230 and the landing portion 2500 and the landing portion 2500 is also moved to the second arm 2250 . Thus, the unmanned flying object 2000 is positioned at the folding position as shown in FIG. 12B, and the unmanned flying object 2000 is completely folded.

On the other hand, the unmanned aerial vehicle 3000 of another embodiment of the present invention is shown in Fig.

The unmanned aerial vehicle 3000 according to another embodiment includes a broadcasting module (not shown) including a speaker 3100 capable of broadcasting to the unmanned aerial vehicles 1000 and 2000 according to the above-described two embodiments .

The speaker 3100 includes an electromagnetic wave generating member (not shown) including an amplifier (not shown) including a magnet for amplifying a signal to be received and a means for converting electric energy into a sound wave, And a shielding means 3110 surrounding the electromagnetic wave generating member so as not to emit the electromagnetic wave generating member.

By this shielding means, a sensor or the like sensitive to electromagnetic waves can be protected from electromagnetic waves, and the degree of detection can be maintained and erroneous operation can be prevented.

In the prior art, a speaker is partially used. However, due to the problem of generation of electromagnetic waves as described above, there is a fear that the sensor may be influenced or the sound wave can not reach far away due to the problem of electromagnetic waves, There was a concern that it could not be transmitted.

Therefore, according to the present invention, it is possible to block electromagnetic waves generated by the use of a speaker having a higher output, and to use a relatively high-output speaker, it is possible to transmit broadcasting clearly and clearly.

The operation of the unmanned aerial vehicle 3000 according to another embodiment having such a configuration will be described in detail with reference to FIG.

The unmanned aerial vehicle 3000 having the speaker 3100 at the ground level by the user can be adjusted to wirelessly broadcast through the flight device adjustment unit 3200. The wireless communication may have a range of 2.4 GHz to 2,4835 GHz, for example. In the broadcasting module, the wireless voice transmission method can be set to the frequency of use of the user.

That is, by selecting the unmanned aerial vehicle 3000 from the flight device adjustment unit 3200 that can remotely control the unmanned air vehicle 3000, The user may speak directly while watching the screen shot from the unmanned air vehicle 3000 and transmit the content to the speaker 3100. For example, And a warning sound may be broadcast through the speaker 3100. FIG.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. The scope of the invention will be determined by the appended claims and their equivalents.
