Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, Fig. 1 is the axonometric drawing of unmanned plane during flying device provided in an embodiment of the present invention, Fig. 2 is this hair
The installation diagram for the unmanned plane and each slewing equipment that bright embodiment provides.
A kind of unmanned plane during flying device provided in an embodiment of the present invention, including unmanned plane 10, protective cover 50, Z-direction swing mechanism
20, X is to swing mechanism 40 and Y-direction swing mechanism 30.
Wherein, unmanned plane 10, Z-direction swing mechanism 20, X are completely set up to swing mechanism 40 and Y-direction swing mechanism 30
In in protective cover 50, unmanned plane 10 shown in Fig. 1 is four axis unmanned planes, and other kinds of unmanned plane can also be applied to we
Case；Z-direction swing mechanism 20 includes the first rotating part, the second rotating part and Z-direction bearing, and the first rotating part is sheathed on the second revolution
Outside portion, and the first rotating part is rotatably connected with the second rotating part by Z-direction bearing, and one end of the second rotating part is connected to nobody
Machine fuselage 110；X to swing mechanism 40 include the pivoted loop being rotatably connected with protective cover 50；Y-direction swing mechanism 30 includes revolution
Axis 380, the both ends that rotating shaft 380 is set to the first rotating part and rotating shaft 380 are connected to pivoted loop, rotating shaft 380 with
At least one of first rotating part and pivoted loop are rotatably connected；The axis of rotation of above-mentioned Z-direction swing mechanism 20 is three
The Z axis of dimension coordinate system, Z axis are also the course axis of unmanned plane simultaneously, X to the axis of rotation of swing mechanism 40 be three-dimensional system of coordinate
X-axis, the axis of rotation of Y-direction swing mechanism 30 are the Y-axis of three-dimensional system of coordinate.
Compared with prior art, unmanned plane during flying device provided by the invention, unmanned plane are rotatable by Z-direction swing mechanism 20
It being connected on rotating shaft 380, rotating shaft 380 can along own axis be connected to pivoted loop and/or Z-direction swing mechanism 20,
Pivoted loop is rotatably connected at protective cover 50, in use, protective cover 50 can wrap up unmanned plane 10 wherein, carries out full side
The protection of position, can keep out the collision in all directions, while Z-direction swing mechanism 20, X between unmanned plane 10 and protective cover 50
Protective cover 50 can be made relative to unmanned plane 10 in X-axis, Y-axis and Z-direction to swing mechanism 40 and Y-direction swing mechanism 30
Upper 360 ° are freely turned round, and borrow protective cover 50 freely to turn round absorption collision in three-dimensional coordinate relative to unmanned plane 10, reduction is touched
The influence to unmanned plane during flying device is hit, so that it is kept the stabilization of posture, continues to fly, avoids falling, the generation of the accidents such as aircraft bombing.
By taking the heading of unmanned plane 10 is parallel with the axis of rotating shaft 380 as an example, when protective cover 50 is by horizontal direction
Tangential wiping when touching, protective cover 50 can be rotated by Z-direction swing mechanism 20 relative to unmanned plane 10；When protective cover 50 is by vertical
The tangential wiping in direction is when touching, protective cover 50 can by X to swing mechanism 40 and/or Y-direction swing mechanism 30 relative to unmanned plane 10
Rotation；Certainly, the external force that unmanned plane 10 is subject in flight course may be the resultant force in multiple directions, without being retouched as above-mentioned
As stating only touched by the wiping in a direction, therefore, generally require by above-mentioned Z-direction swing mechanism 20, X to swing mechanism 40 with
And the cooperation of Y-direction swing mechanism 30 plays a role and lays down external force.

Lid 210 is connected.
It is understood that bearing internal external circle when relatively rotating, is not to be substantially parallel between Internal and external cycle, has rolling
It is dynamic, if the tight fit of bearing internal external circle cannot be completely secured in processing precision of products, this shaking is also will increase, to avoid this
One problem, in embodiments of the present invention, as shown in Figure 4-Figure 6, Z-direction bearing includes the second axis of Z-direction first bearing 240 and Z-direction
Holding 240a, bearing mounting hole 252 includes the path section 252b of two major diameter section 252a of major diameter section 252a and connection at both ends, and two
A Z-direction bearing gland 230/230a compresses the outer ring of the outer ring of Z-direction first bearing 240 and Z-direction second bearing 240a respectively
On the step surface of two major diameter section 252a；The end face of connection end cap 210 contacts at the inner ring of Z-direction first bearing 240, connecting pole
260 step surface contacts at the inner ring of Z-direction second bearing 240a.
By using two arranged for interval bearings, two bearings is made to cancel out each other mutual shaking, it will when ensureing Z-direction rotation
Above-mentioned shaking is reduced to minimum, and other than Z-direction swing mechanism 20, X can also be adopted to swing mechanism 40 and Y-direction swing mechanism 30
The opposite of bearing internal external circle is offset with similar structures to shake.
From figure 5 it can be seen that the outer ring of Z-direction first bearing 240 and the outer ring of Z-direction second bearing 240a are respectively by Z
On two step surfaces being pressed in bearing mounting hole 252 to bearing gland 230/230a, step surface on connecting pole 260 and
The inner ring of the inner ring to Z-direction first bearing 240 and Z-direction second bearing 240a limit respectively for the end face of connection end cap 210,
Realize the axial limiting to Z-direction first bearing 240 and Z-direction second bearing 240a.
Above-mentioned technical proposal is advanced optimized, the installation for ease of plug-in device 120 and cabling are set in connection end cap 210
It is equipped with first through hole 211, the second through-hole 261 is provided on connecting pole 260, after connection end cap 260 coordinates with connecting pole 260, the
One through-hole 211 is connected to the opening for being formed and entering the second rotating part inner cavity for the cable 130 of plug-in device 120 with the second through-hole 261,
As shown in Figure 4 and Figure 5, in this way, the second rotating part can form plug-in device 120 in the end face of 260 side of connection end cap
Mounting surface, cable 130 enter the inner cavity of the second rotating part from the side of the second rotating part, as shown in Figure 7 and Figure 8.Certainly, should
Illustrate, the aperture position of the second rotating part is not limited to position shown in figure, and those skilled in the art can basis
The characteristics of plug-in device, selects cabling mode, does not limit herein.
