Express delivery unmanned plane
Technical field
This utility model is related to unmanned plane field, and in particular to express delivery unmanned plane field.
Background technology
Unmanned plane is used for express delivery, due to low cost, efficiency high, VTOL, flexible operation, is more and more weighed
Depending on.
In prior art, unmanned plane express delivery technical scheme is to be fixedly connected goods with multi-rotor unmanned aerial vehicle, is combined as one
Individual entirety, due to the scrambling of each transport goods, i.e. weight and shape is differed, cause as overall many rotors without
Man-machine center of gravity is not fixed.And center of gravity is particularly important for multi-rotor unmanned aerial vehicle, its stability and mobility are directly affected, because
This, under prior art, is required for carrying out counterweight to goods before each cargo transport, to fix unmanned plane center of gravity,
Also goods is fixed in addition, in case goods is moved during unmanned plane during flying and causes the center of gravity of unmanned plane to be sent out
It is raw to change.The efficiency for so allowing for unmanned plane express delivery is substantially reduced.
Utility model content
For defect of the prior art, this utility model provides a kind of stability and mobility not by goods weight and shape
The express delivery unmanned plane that shape affects.
A kind of express delivery unmanned plane that this utility model is provided includes multi-rotor unmanned aerial vehicle body and cargo hold;Many rotors without
Connect the cargo hold by two axle heads at man-machine body central;The two axles head includes the longitudinal axis and transverse axis;The longitudinal axis leads to
Cross the first hinged block to be connected with multi-rotor unmanned aerial vehicle body;The transverse axis and axis oriented normal, the transverse axis is hinged with the longitudinal axis;It is described
Transverse axis connects the cargo hold by the second hinged block.
That is multi-rotor unmanned aerial vehicle body is connected at its center the cargo hold of arrangement of goods by two axle heads,
Two axle heads are horizontally and vertically made up of axially vertical, longitudinal axis two ends and cargo hold top connection, horizontally and vertically between be hinged,
I.e. transverse axis can be hinged by hinged block, or be hinged by hinge hole around the axial-rotation of the longitudinal axis.Such goods
When the article deposited in cabin is uneven, self-balancing can be carried out by the rotation between horizontally and vertically, so that unmanned plane
It is more steady.
Preferably, through hole is set described in above-mentioned express delivery unmanned plane on transverse axis, and the through hole is axially perpendicular to transverse axis axial direction,
The longitudinal axis penetrates the through hole and is hinged with transverse axis.
That is, used as jointed shaft, in penetrating the through hole arranged on transverse axis, transverse axis can be around the axle of the longitudinal axis for the longitudinal axis itself
To rotation.So it is not required to additional articulated mounting to be capable of achieving to be hinged purpose, and horizontally and vertically connects more close and firm so that nothing
Man-machine entirety is more stable, and weight is lighter.
Preferably, above-mentioned express delivery unmanned plane also includes undercarriage;The undercarriage is reclinate strip;The cargo hold
It is shaped as cuboid, undercarriage is set on vertical four ribs of the cargo hold.
That is, cargo hold is cuboid, when goods does not place inequality, the pressure to four sides can be converted into, and
Reclinate strip is set on the rib of four vertical directions, when so landing, the face two when certain one side is under pressure
Two undercarriages on bar vertical edge can contact ground so that also more steady during its landing.
Preferably, longitudinal axis two ends described in above-mentioned express delivery unmanned plane are hinged with multi-rotor unmanned aerial vehicle body by described first
Block connects;First hinged block is two, and on first hinged block hinge hole is arranged;The longitudinal axis two ends respectively penetrate two
In hinge hole on individual first hinged block.
That is, around the axial-rotation of hinge hole in the hinge hole that can arrange on the first hinged block of the longitudinal axis,
The freedom of movement between cargo hold and multi-rotor unmanned aerial vehicle body can so be increased, goods is further reduced and loaded inequality to nothing
The impact of man-machine stability.
Preferably, transverse axis two ends are connected with cargo hold by second hinged block described in above-mentioned express delivery unmanned plane;It is described
Second hinged block is two, and on second hinged block hinge hole is arranged;The transverse axis two ends respectively penetrate two second and are hinged
In hinge hole on block.
That is around the axial-rotation of hinge hole in the hinge hole that transverse axis can be arranged on the second hinged block.So may be used
To increase the freedom of movement between cargo hold and multi-rotor unmanned aerial vehicle body, further reduce goods and load inequality to unmanned plane
The impact of stability.
Preferably, above-mentioned express delivery unmanned plane also includes the first servomotor and the second servomotor;The first servo electricity
Machine controls transverse axis around its axial rotation;The second Serve Motor Control longitudinal axis is around its axial rotation.
That is rotation horizontally and vertically is controlled by servomotor, so can ensure that cargo hold self-balancing
Shi Buhui oscillates so that unmanned plane during flying is more stable.
It is further preferred that above-mentioned express delivery unmanned plane also includes controller and gyro sensor;The gyro sensors
Device is placed in the cargo hold top, for measuring cargo hold horizontality;The controller feeds back according to the gyro sensor
Signal controls the rotation of first servomotor and the second servomotor, for realizing that the balance of cargo hold is controlled.
That is, the gyro sensor feedback that the rotation of the servomotor is installed by controller according to cargo hold top
Poised state signal be controlled, can so realize the autobalance of whole cargo hold.
Preferably, undercarriage described in above-mentioned express delivery unmanned plane and cargo hold integrated design.I.e. undercarriage is installed on cargo hold
On, with cargo hold integrated design, can so mitigate the weight of unmanned plane body, in landing, four undercarriages can also be same
When land because cargo hold remains horizontality.
In sum, the express delivery unmanned plane that this utility model is provided, is connected by the two axle heads for arranging with cargo hold, can
Ground gravity center shift is caused because of goods weight or distribution of shapes imbalance come autobalance cargo hold by rotation horizontally and vertically,
So that whole express delivery unmanned plane during flying is more steady safe.
