When needing to carry out Aerial photography, drive component 3 drives luggage carrier 2 to move downward while drive foot stool 4 to turn upwards
Dynamic to be stored, when luggage carrier 2 and foot stool 4 are moved at the position as shown in Fig. 1-Fig. 2, luggage carrier 2 moves downwardly to
End of travel, while foot stool 4 is also rotated up to end of travel, holder is started to work, at this time 100 body 1 of unmanned plane and foot stool 4
Away from luggage carrier 2, so as to avoid parts on 100 body 1 of unmanned plane and foot stool 4 blocks taking lens and claps
Take the photograph dead angle；When unmanned plane 100 needs landing after the completion of work of taking photo by plane, drive component 3 drives luggage carrier 2 to move up and at the same time
Driving foot stool 4 rotates down, and Fig. 3-Fig. 4 moves up the procedure chart rotated down with foot stool 4 for luggage carrier 2, when 2 He of luggage carrier
When foot stool 4 is moved at the position shown in Fig. 5-Fig. 6, luggage carrier 2 moves up to end of travel and foot stool 4 is swung down to row
Journey end, when unmanned plane 100 drop to ground, foot stool 4 is contacted with ground to be supported to unmanned plane 100, so as to avoid
Unmanned plane 100 causes to damage when landing to luggage carrier 2 and capture apparatus.
Unmanned plane 100 according to embodiments of the present invention, is connected by luggage carrier 2 and foot stool 4 with drive component 3, driving
Component 3 can drive luggage carrier 2 and foot stool 4 while move, so as to simplify the overall structure of unmanned plane 100.Needing to be clapped
Take the photograph or take article in luggage carrier 2 when, drive component 3 drives luggage carrier 2 down away from 100 body of unmanned plane, 1 He
Foot stool 4 interferes to avoid 100 body 1 of unmanned plane and foot stool 4 to shooting or fetching article, drives and carries in drive component 3
During rack 2 moves down, drive component 3 drives foot stool 4 to be rotated up being stored at the same time, so as to greatly shorten
The stroke that luggage carrier 2 moves downward, the overall structure of unmanned plane 100 is simpler and the motion process of luggage carrier 2 is more steady
It is fixed and steady, it thereby may be ensured that shooting quality.When unmanned plane 100 lands, drive component 3 drives what foot stool 4 moved up
At the same time drive foot stool 4 to be rotated down to be supported to unmanned plane 100, avoid unmanned plane 100 land when to luggage carrier 2 and carrying
Article in luggage carrier 2 causes to damage.
In some embodiments of the invention, as shown in Fig. 7-Figure 10, each foot stool 4 includes the first straight line being sequentially connected
Section 41, bending segment 42 and second straight line section 43, in other words, first straight line section 41 is connected with bending segment 42, bending segment 42 and the
Two straightways 43 be connected, i.e., bending segment 42 is connected between first straight line section 41 and second straight line section 43, first straight line section 41 and
Drive component 3 is pivotably connected, and foot stool 4 rotates under the driving of drive component 3 around drive component 3, the first straight line section of foot stool 4
There is angle between 41 and second straight line section 43.In addition, be connected between bending segment 42 and body 1 by guide frame, when
Drive component 3 drives first straight line section 41 so that second straight line section 43 is horizontal-extending when luggage carrier 2 moves downwardly to extreme position,
When luggage carrier 2 moves up to extreme position drive component 3 drive first straight line section 41 so that 43 pairs of second straight line section nobody
Machine 100 is supported.
Specifically, bending segment 42 is coordinated by guide frame with body 1 and is connected, and rotation of the guide frame to foot stool 4 rises
To guiding role, when drive component 3 drives luggage carrier 2 to move downwardly to extreme position, foot stool 4 is under the guiding of guide frame
Turn at the fully expanded position as shown in Fig. 1-Fig. 2, first straight line section 41 is inclined upwardly extension at this time, second straight line section
43 extend substantially horizontally, and so as to avoid foot stool 4 from being interfered to shooting or fetching article, are carried when drive component 3 drives
When rack 2 moves up to extreme position, foot stool 4 turns to the position as shown in Fig. 5-Fig. 6 under the guiding of guiding structural
Place, first straight line section 41 extends substantially horizontally at this time, and second straight line section 43 tilts down extension to prop up unmanned plane 100
Support.By setting guide frame between bending segment 42 and body 1, so that guiding role, Ke Yibao are played in the rotation to foot stool 4
It is more steady reliable to demonstrate,prove the rotation of foot stool 4, so as to improve the reliability of the work of unmanned plane 100.
Alternatively, guide frame includes sliding slot 421 and sliding axle 11, and sliding slot 421 is located at one in body 1 and bending segment 42
On a, sliding axle 11 is located on another in body 1 and bending segment 42, that is to say, that and sliding slot 421 can be located on body 1,
It can also be located on bending segment 42, sliding axle 11 can be located on body 1, can also be located on bending segment 42, when sliding slot 421 is set
When on body 1, sliding axle 11 is correspondingly arranged on bending segment 42, and when sliding slot 421 is located on bending segment 42, sliding axle 11 corresponds to
It is located on body 1 (as shown in Fig. 7-Figure 10).In addition, sliding slot 421 is formed as arc, wherein sliding axle 11 coordinates in sliding slot 421
It is interior, pass through the rotation relative to slip guiding foot stool 4 between sliding axle 11 and sliding slot 421.
Further, as shown in Fig. 7-Figure 10, sliding axle 11 is formed on body 1, and sliding slot 421 is correspondingly formed in bending segment
On 42, and sliding slot 421 extends along the bending direction of bending segment 42, so as to preferably guide the rotation of foot stool 4.
Alternatively, as shown in figs 1 to 6, sliding axle 11 is located at the lower part of body 1, consequently facilitating sliding axle 11 and sliding slot
Cooperation between 421, and then easy to the mating connection of body 1 and foot stool 4, simplify assembly technology.
In some embodiments of the invention, as shown in Fig. 1-Figure 10, drive component 3 includes motor 31 and leading screw 32, electricity
Machine 31 is located on body 1, and leading screw 32 includes screw rod 321 and the nut 322 being set on screw rod 321, and screw rod 321 is along the vertical direction
Extension, the upper end of screw rod 321 are connected with motor 31, and foot stool 4 is pivotably coupled on nut 322, luggage carrier 2 and nut 322
It is connected.Motor 31 is connected with screw rod 321, and rotating driving screw rod 321 by motor 31 rotates, and then drives nut 322 along screw rod
321 move up and down.For example, motor 31 rotates forward, screw rod 321 is rotated forward with motor 31, by screw rod 321 be driven forward nut 322 to
Upper movement；Motor 31 inverts, and screw rod 321 is inverted with motor 31, and being driven reverse nut 322 by screw rod 321 moves downward.Foot stool
4 are pivotly connected with nut 322, and luggage carrier 2 is connected with nut 322, by the up and down motion of nut 322, so as to drive
Dynamic load rack 2 moves up and down, while drives foot stool 4 to be rotated upwardly and downwardly around nut 322.
