The unmanned vehicle 2 specifically may include：Body 21, power plant 22, antenna 1, flight controller and transmitting-receiving control
Unit processed etc..Wherein, power plant 22 includes：Motor 222 and rotor 221.Rotor 221 may include middle part interconnecting piece and
The fin stretched out by interconnecting piece, 222 output shaft of motor are fixedly connected with interconnecting piece.Motor 222 is used to that rotor 221 to be driven to rotate,
To provide the power of the flight of unmanned vehicle 2.Wherein, antenna 1 is electrically connected with transmitting-receiving control unit, in the control of transmitting-receiving control unit
System is lower to be communicated with ground control station.Ground control station such as can be remote controler, pass through remote control control unmanned vehicle 2
Take off, flight attitude, direction and landing etc..Wherein, flight controller is connect with transmitting-receiving control unit, for according to control
Signal controls unmanned vehicle 2.
With reference to shown in Fig. 7, in the present embodiment, unmanned vehicle 2 is specially quadrotor unmanned vehicle, needs to illustrate
It is unmanned vehicle 2 or six rotorcraft, eight-rotary wing aircraft etc., certainly, unmanned vehicle 2 or list
Rotor craft, the utility model are not construed as limiting this.
Antenna 1 in the unmanned vehicle 2 of the present embodiment is specifically and the antenna 1 of the offer of embodiment one is identical, herein no longer
It repeats.It should be noted that the antenna 1 of embodiment two or embodiment three can also be applied in the unmanned vehicle 2, equally may be used
Promote the flying height of unmanned vehicle 2.
When ground control station needs to control unmanned vehicle 2, ground control station can fly to nobody in the form of an electromagnetic wave
Row device 2 sends control signal, and antenna 1 receives the control signal that ground control station is sent under the control of transmitting-receiving control unit, or
Person, by antenna 1, earthward control station sends feedback signal to unmanned vehicle 2.For example, ground control station needs unmanned vehicle
2 fly upwards from current location in 1 minute 100 meters when, ground control station to unmanned vehicle 2 send signal, transmitting-receiving control
Unit controls antenna 1 and receives the control signal, then by the signal transmission to flight controller, flight controller to the signal into
Row parsing obtains unmanned vehicle 2 and flies upwards from current location in 1 minute 100 meters of command information, then flight controller
Control unmanned vehicle 2 is acted accordingly, so that unmanned vehicle 2 flies 100 meters upwards in 1 minute.
Since the antenna 1 of the unmanned vehicle 2 includes the first oscillator unit 11 in the vertical direction and is connected to first
Second oscillator unit 12 vertical with the first oscillator unit 11 of 11 bottom end of oscillator unit, antenna 1 is shallower in zero depth of upper and lower,
Gain increases, and to make unmanned vehicle signal when in surface greatly enhance, ensure that unmanned vehicle 2 just
The stability and reliability of signal when top, to improve the flying height of unmanned vehicle 2.
Wherein, the lower section of body 21 is additionally provided with tripod 23, and tripod 23 provides support when landing for unmanned vehicle 2.Tool
When body is realized, the antenna 1 of unmanned vehicle 2 can be arranged on the ontology of body 21, can also be arranged below body 21
On tripod 23.More preferred, with reference to shown in Fig. 8, the antenna 1 of the unmanned vehicle 2 of the present embodiment is specifically located at tripod 23
It is interior, by being arranged antenna 1 in tripod 23, the space that tripod 23 leaves unused can not only be fully utilized, and can avoid day
The problem that line 1 is set in the ontology of body 21 and causes the design of 21 surface structure of body not beautiful enough occurs.
Shown in Fig. 8, tripod 23 specifically includes：Sequentially connected first linkage section 231, the second linkage section 232
With third linkage section 233, wherein the top of the first linkage section 231 is connect with body 21, the top of third linkage section 233 and machine
Body 21 connects, and the second linkage section 232 is connected between the bottom end and the bottom end of third linkage section 233 of the first linkage section 231.It can be with
Understand, the inside of the first linkage section 231 of tripod 23, the second linkage section 232 and third linkage section 233 communicates.The
One oscillator unit 11 is correspondingly arranged in the first linkage section 231 or third linkage section 233, and the second oscillator unit 12 is correspondingly arranged
In the second linkage section 232.First oscillator unit 11 is located on the vertical direction of unmanned vehicle 2, the second oscillator unit 12
In in the horizontal direction of unmanned vehicle 2.
Wherein, the first linkage section 231, the second linkage section 232 and third linkage section 233 are integrally formed, for example, by primary
The property each linkage section of die casting and form tripod 23, by the way that each linkage section to be integrally formed, the stability of entire tripod 23 can be improved,
And then improve stability when unmanned vehicle 2 lands.Certainly, each linkage section can also be fabricated separately, and be then mounted on again
Together.
Further, it is additionally provided in tripod 23 for the first oscillator unit 11 and/or the progress of the second oscillator unit 12
The positioning region of positioning.It is positioned by positioning region pair the first oscillator unit 11 and/or the second oscillator unit 12, prevents nobody
In flight course, the problem that tripod 23 shakes and antenna 1 is caused to move occurs aircraft 2, improves the stability of antenna 1,
And then improve the stability of signal transmission.When specific implementation, positioning region can multiple move towards spaced along antenna 1
Positioning protrusion or locating ring with opening.
Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model, rather than limits it
System；Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should
Understand：It still can be with technical scheme described in the above embodiments is modified, either to which part or whole
