Body main shaft is overlapped, and motor is provided with above rotor, and cross eccentric is arranged on the deflection that center of gravity is realized inside aircraft body,
LED shows that light pearl is arranged on rotor bottom side, and the wide angle cameras is arranged on aircraft body upper end.
Further, the cross eccentric includes battery and cross guide rail, and battery is fixed on the sliding block of cross guide rail
On, do independent without coupled motions on transverse direction, longitudinal direction along guide rail, realize the deflection of center of gravity, adjust unmanned plane body posture.
Further, the aircraft body is cylindrical structure.
Further, the wide angle cameras top is provided with spherical mirror.
Further, the motor uses close coupled type DC brushless motor.
Further, the unmanned plane is provided with VTOL frame.
Further, the rotor is foldable.
Beneficial effect:
1st, the present invention is using identical but two opposite underneath type rotor counter balance torques of steering, without transmission mechanism,
Compact conformation, lightweight, action is rapid, by changing laterally opposed position of the barycenter relative to whole system, using gravity with
The change of posture is realized in the cooperation of bottom rotor, and controlling organization is simple;Light is shown by the LED for being arranged on lowermost end rotor bottom side
Pearl can be realized stealthy.
2nd, the present invention using rotor and the battery that is fixed on cross guide rail can posture change, mechanism is simple;And phase
For other utilize aerodynamic force control posture aircraft (such as fixed-wing, four rotors), the response speed of Moving mass control faster,
Avoid the time delay in control loop.
3rd, aircraft body of the present invention is cylindrical structure, is more suitable for carrying, convenient in carrying.
4th, the spherical mirror that wide angle cameras top of the present invention is set can reach 360 degree of visual angle, directly by it is lower extremely
It is upper to be shot, realize that earth observation is monitored, monitoring range is wide.
5th, the present invention use close coupled type DC brushless motor, can realize the supply of three phase electric machine electric power in rotation process with
And ensure the uniformity of the sense of current.
6th, the propeller blade of rotor of the present invention is foldable, and engaged position is small, is readily transported, launches.
Brief description of the drawings
Fig. 1 is overall structure diagram of the invention;
Fig. 2 is the partial view of cross guide rail of the present invention.
Wherein, 1- wide angle cameras, 2- batteries, 3- cross guide rails, 4- close coupled type DC brushless motors, 5- rotors, 6- hangs down
Straight undercarriage, 7- propeller blades.
Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
For underneath type coaxial double-rotary wing unmanned plane, due to the limitation of volume, control the feature area of rudder face smaller
And relative velocity is smaller so that control moment does not reach the index of design, so the present invention is by the way of " Moving ",
" Moving " is, by changing laterally opposed position of the barycenter relative to whole system, to utilize the cooperation reality of gravity and bottom rotor
The change of existing posture.
The invention provides a kind of underneath type coaxial double-rotary wing unmanned plane, realized using cross eccentric " rotten
The heart ", the unmanned plane includes two groups of rotors 5, aircraft body, cross eccentric, LED and shows light pearl, wide angle cameras 1 and be total to
Shaft type DC brushless motor 4.
As shown in figure 1, aircraft body is cylindrical structure, wide angle cameras 1 is arranged on aircraft body upper end, rotor 5
Installed in aircraft body bottom, two groups of upper and lower co-axial alignments of rotor 5 are turned to opposite and overlapped with aircraft body main shaft,
The top of rotor 5 is provided with close coupled type DC brushless motor 4, and cross eccentric is arranged on inside aircraft body and realizes center of gravity
Deflection, LED shows that light pearl is arranged on the bottom side of rotor 5, and it can send corresponding light according to residing flight environment of vehicle color, by
The high speed rotation of rotor 5, reaches merging for aircraft color and surrounding environment, so as to realize that the vision to human eye of aircraft is hidden
Body.Unmanned plane is provided with VTOL frame 6, can be without this device when radiation pattern is projectile or big gun is penetrated.
As shown in Fig. 2 cross eccentric includes battery 2 and cross guide rail 3, battery 2 is fixed on the sliding block of cross guide rail 3
On, do independent without coupled motions on transverse direction, longitudinal direction along cross guide rail 3, realize the deflection of center of gravity, adjust unmanned plane body
Posture.Concrete methods of realizing is, when needing to change posture, and the adjustment main counterweight of aircraft is the position of battery, makes aircraft
Center of gravity occur lateral deflection, deviate one thin tail sheep of main shaft, because the direction of lift is overlapped with the main shaft of aircraft all the time, because
This is after deviation of gravity center main shaft, and lift just produces a smaller moment of torsion to system, so that the posture of system changes,
The response speed of Moving mass control is faster, it is to avoid the time delay in control loop.
The top of wide angle cameras 1 is provided with spherical mirror, when photographic subjects are located at aircraft upper end, is most pushed up positioned at aircraft
The wide angle cameras 1 at end can not directly keep a splendid viewing angles by any device.When reference object is to ground
During target, the spherical mirror combination wide angle cameras 1 at top can realize that 360 omnidirectional shoots, but when being due to shooting, wide-angle is taken the photograph
Camera 1 is located at the top of aircraft body, and the subregion of the bottom of rotor 5 is difficult to photograph, i.e., detector has dead angle, can pass through
Aircraft changes its position, or constantly motion makes up the shortcoming of dead angle presence.
Every group of rotor 5 is made up of four propeller blades 7, and the propeller blade 7 of rotor 5 can be folded up, and takes position
Put small, be readily transported, launch.When DCB Specimen hovers, because the contraction of upper rotor wake is expanded by the drainage of lower rotor,
So as to add the effective district of wake flow, it is possible to eliminate the eddy flow loss of wake flow, therefore with more preferably hovering efficiency.Close coupled type
DCB Specimen does not need extra constitutional balance moment of torsion, eliminates many drive mechanisms, therefore the gross weight of aircraft can also drop significantly
Low, structure is compacter, and shared physical dimension is smaller, and close coupled type rotor craft air force keeps symmetrical, because
This have higher driving efficiency, be adapted to minimize, can take off vertically, the unmanned surveillance plane of hovering.
In summary, presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention's
Within protection domain.
