There is spacing between one installation portion 112.
During being taken photo by plane using above-mentioned unmanned plane 200, the head assembly 100 hangs on the unmanned plane
On fuselage 210, for unmanned plane 200 in flight course, fuselage 210 can produce the higher vibration of frequency, and to the head assembly
100 transmit.In addition, in the change of flight state (such as change of flight direction or change fuselage angle of inclination) in the air of unmanned plane 200
Or during by aerial airflow influence, the fuselage 210 of unmanned plane 200 can produce the relatively low vibration of frequency, and to the head group
Part 100 transmits.When fuselage 210 produces the higher vibration of frequency, the amplitude of fuselage 210 is smaller, first damper element 13
Second connector 12 is allowed to be moved relative to the first connector 11 by elastic deformation, the frequency is higher to shake to filter
It is dynamic, so that head 20 and the held stationary of camera device 30, so that it is guaranteed that the picture that camera device 30 photographed is clear and steady.
When fuselage 210 produces the relatively low vibration of frequency, the amplitude of fuselage 210 is larger, accordingly, the bullet of first damper element 13
Property deformation is larger；The spacing of the connector 12 of first connector 11 and second changes greatly, first connector 11 and
When the spacing of two connectors 12 increases to certain numerical value, second stop part 143 abuts second connector 12, to prevent
The spacing of the connector 12 of first connector 11 and second further expands, so as to play cushioning effect.In the process,
The damping effect of one damper element 13 and the second damper element 14 is superimposed, i.e. both have an effect jointly, so as to add damping
The damping of device 10 and rigidity, and then filter out the relatively low vibration of the frequency.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；At this
Under the thinking of invention, it can also be combined between the technical characteristic in above example or different embodiments, step can be with
Realized with random order, and many other changes of the different aspect of the present invention as described above be present, for simplicity, they do not have
Have and provided in details；Although the present invention is described in detail with reference to the foregoing embodiments, the ordinary skill people of this area
Member should be understood：It can still modify to the technical scheme described in foregoing embodiments, or to which part skill
