Ground and implicitly understand, embodiment described herein can be combined with other embodiments.
Refering to fig. 1 with shown in Fig. 2, by the structural schematic diagram for the unmanned vehicle that the utility model embodiment provides.This
Unmanned vehicle in embodiment can be more rotor unmanned aircrafts, be illustrated by taking quadrotor unmanned vehicle as an example here
Property explanation, certainly, in other implementations, the unmanned vehicle can also be other kinds of unmanned vehicle.
The unmanned vehicle includes fuselage 1, bindiny mechanism 2 and at least one wing 3, and the wing 3 passes through the company
Connection mechanism 2 is rotatably installed on the fuselage 1;The wing 3 in the unmanned vehicle flight for providing additionally
Lift, in the utility model embodiment, the unmanned vehicle is described under the action of incoming air in flight course
Wing 3 automatically adjusts the angle of attack.During unmanned vehicle flies, under the action of incoming air, the angle of attack of wing 3 can be with
It is adjusted in available range of angles of attack, lift is provided for unmanned vehicle, improve the flight efficiency of unmanned vehicle.
As shown in figure 3, Fig. 3 is the curve synoptic diagram of the pitching moment slope of curve and lift coefficient of wing 3, wherein X-axis
For the lift coefficient of wing 3, lift coefficient can characterize the angle of attack of wing 3 here, and Y-axis indicates the pitching moment of wing 3, Y-axis
Positive axis indicate that new line pitching moment, the negative axis of Y-axis indicate nose-down pitching moment.The pitching moment slope of curve of the wing 3
Relative position between the pivot center that rotates relative to fuselage 1 of wing and unmanned vehicle aerodynamic center is related.When wing 3
The distance between rear of the pivot center and wing 3 that are rotated relative to fuselage 1 is equal to the aerodynamic center and wing 3 of wing 3
The distance between rear, i.e., when the pivot center is in its aerodynamic center position, no matter how its angle of attack changes, wing 3
Pitching moment it is constant;When the distance between the rear of pivot center and wing 3 that wing 3 is rotated relative to fuselage 1 is less than machine
The aerodynamic center of the wing 3 and the distance between the rear of wing 3, i.e., when the pivot center is located at after aerodynamic center, wing 3
The pitching moment slope of curve be positive value, from the point of view of the curve and the intersection point A (zero lift moment point) of X-axis, the increase of the angle of attack can produce
Raw new line pitching moment, the new line trend of the wing 3 to further increase, the reduction of the angle of attack will produce nose-down pitching moment,
The trend of bowing of wing 3 to further increase produces the unstable characteristic of 3 angle of attack of wing;When wing 3 is relative to fuselage
The distance between the pivot center of 1 rotation and the rear of wing 3 are more than between the aerodynamic center and the rear of wing 3 of wing 3
Distance, i.e., before the rotary shaft of wing 3 is located at its aerodynamic center when, the pitching moment slope of curve of wing 3 is positive value, with this
From the point of view of the intersection points B (zero lift moment point) of curve and X-axis, the increase of the angle of attack can make wing 3 generate nose-down pitching moment, to provide
Reduce the trend of the angle of attack of wing 3, the reduction of the angle of attack can make wing 3 generate new line pitching moment, increase wing 3 to provide

Aerodynamic center and wing 3 the distance between rear when, during unmanned vehicle flies, in the effect of incoming air
Under, the angle of attack of the wing 3 is stabilized in the target angle of attack.Wherein, the target angle of attack can be less than any of stall angle
One angle of attack, it is generally the case that the target angle of attack can be determined according to stall angle with a safety coefficient, such as safety system
Number can be 0.7, and the target angle of attack can be the product of stall angle and safety coefficient, for example, stall angle is 10 degree, at this point,
The target angle of attack can be 7 degree.
In certain embodiments, the target angle of attack is determined according to the rear camber of the wing 3.Specifically, target
Zero liter of pitching moment of the angle of attack corresponding angle of attack when can be zero liter of pitching moment, the wing 3 is according to after the wing 3
Edge camber determines, therefore can accordingly adjust zero liter of pitching power of the wing 3 by changing the rear camber of the wing 3
Square, the size of zero liter of pitching moment are the intersection point of pitching moment curve and X-axis in Fig. 3.If the pitching moment of wing 3 is oblique
Rate is negative, i.e., the distance between wing 3 is rotated relative to fuselage 1 pivot center and the rear of wing 3 are more than the pneumatic of wing 3
When center and the distance between the rear of wing 3, the corresponding angle of attack of lift coefficient is target when wing 3 is in zero liter of pitching moment
The angle of attack, during unmanned vehicle flies, under the action of incoming air, wing 3 can be attacked by stablizing naturally at this
On angle, to persistently generate stable lift in unmanned vehicle flight course.
The quantity of the wing 3 is matched according to the total lift demand of the unmanned vehicle, and at least one wing 3
Total life center and the position of centre of gravity of unmanned vehicle essentially coincide, since the flight of unmanned vehicle is put down by lift
Weigh the gravity of its own, when the total life center of the wing 3 differs larger in position with the center of gravity of unmanned vehicle, meeting
Cause to increase the unstable trend of unmanned vehicle, influences the stabilized flight of the unmanned vehicle.
Meanwhile the quantity of the wing 3 can be selected according to actual demand.For example, when the quantity of the wing 3 is one
When a, the wing 3 can be rotatably installed in 1 top of the fuselage or lower part by the bindiny mechanism 2;When the wing 3
Quantity be at least two when, as shown in figure 4, at least two wing 3 is symmetrically rotatably installed in the two of the fuselage 1
Side;Certainly, the installation site of above-mentioned wing 3 is intended only as example, in actual installation process, according to the unmanned vehicle

The stability moved in the flight course of the unmanned vehicle for increasing the wing 3, avoids the wing 3 at nobody
When the flight attitude suddenly change of aircraft, cause the violent concussion of the wing 3;For unmanned vehicle, especially more rotations
For wing unmanned vehicle, the dynamic for being frequently accompanied by flight attitude according to environmental change or flight demand in flight course becomes
Change, for example, conventional dogled, height rises or the variation of the flight attitudes such as decline can all lead to the machine in unexpected occur
The violent concussion of the wing 3, when the wing 3 shakes, can influence nobody since the wing 3 is rotatably installed on the fuselage 1
The flight stability of aircraft.Therefore, in order to increase the wing 3 moved in the flight course of the unmanned vehicle it is steady
Qualitative, damping material 23 is arranged in contact position of the present embodiment between the installation axle 21 and the installation axle component 22,
To reduce concussion of the wing 3 in the flight attitude suddenly change of unmanned vehicle.Wherein, the damping material 23 can be
It is one or more in rubber, plastics, damping grease, damping oil.
The unmanned vehicle further includes tractive unit 4, is hovering or is flying at low speed opportunity for limiting unmanned vehicle
The angle of attack of the wing 3;In conjunction with shown in Fig. 1, when the unmanned vehicle be in hovering or low-speed operations scene under, in the effect of gravity
Under, the wing 3 can be in hang, and the angle of attack of wing 3 is likely larger than stall angle, when the wing 3 is sagging, if institute
It states unmanned vehicle to fly at low speed, then the wing 3 can form resistance to influence the flight shape of the unmanned vehicle
Tractive unit 4 is arranged in state, therefore, the present embodiment, limits the angle of attack of unmanned vehicle wing 3 in hovering or low-speed operations, this
Sample can reduce the flight resistance that wing 3 is brought to unmanned vehicle when unmanned vehicle flies at low speed device.Wherein, described
Tractive unit 4 may include one or more elastomeric elements (such as spring, rubber material etc.).
In certain embodiments, one end of the tractive unit 4 connects the fuselage 1, and the other end connects the rear of wing 3,
