It should be noted that, whether the first shock absorbing structure 10 is connected to the body 1 or the horn 2 may be set according to the size of the body 1, for example, when the size of the body 1 is large enough (for example, the length and the width of the body 1 are respectively larger than a preset value), the first shock absorbing structure 10 may be connected to the body 1 or the horn 2. When the size of the fuselage 1 is small, it is necessary to attach the first shock-absorbing structure 10 to the horn 2 in order to maintain the balance of the drone.

Referring to fig. 7, a through hole (not shown) is formed in the body 1, and the connecting shaft 30 is inserted through the through hole. The diameter of the through hole is larger than that of the connecting shaft 30, so that the connecting shaft 30 can be conveniently drawn out of the machine body 1, and the unmanned aerial vehicle can be conveniently folded under a non-operation state.

The cloud deck 301 can also be connected to the portion above the fuselage 1 through the first shock-absorbing structure 10, so as to connect the cloud deck 301 to the unmanned aerial vehicle, and the cloud deck 301 above the fuselage 1 is damped through the first shock-absorbing structure, as shown in fig. 8.

Alternatively, the first mounting portion 11 is located above the body 1. Of course, the first support 12 and the first shock absorbing member 13 may also be located above the fuselage, so that the first shock absorbing structure 10 can be conveniently connected to the drone.

The first mounting portion 11 is used for connecting the cradle head 301, so that the cradle head 301 can be connected to the unmanned aerial vehicle. Optionally, the cloud platform 301 and the first mount portion 11 are fixedly connected in a detachable manner, for example, the cloud platform 301 and the first mount portion 11 are fixedly connected in a threaded manner, a clamping manner, or another detachable connection manner, so that the cloud platform 301 is conveniently detached from the unmanned aerial vehicle.

In addition, the first mounting portion 11 is further connected to the connecting shaft 30 to support the first mounting portion 11 through the connecting shaft 30. The connection mode of the first mounting portion 11 and the connection shaft 30 can be set according to the requirement, for example, in one embodiment, the first mounting portion 11 is sleeved on the connection shaft 30 and is fixed to the connection shaft 30 through a connecting member such as a thread, so that the stability of the first mounting portion 11 is ensured, and the implementation mode is simple. In another embodiment, the first mounting portion 11 can be connected to the connecting shaft 30 by snapping or other means.

Correspondingly, the first supporting members 12 are also plural and correspondingly matched with the first shock absorbing members 13. The plurality of first supporting members 12 are distributed around the first mounting portion 11, and each first supporting member 12 is connected to the horn 2 through the first damper 13. After the cradle head 301 is mounted on the first mounting portion 11, the component forces generated by the first shock absorbing members 13 are combined into an elastic force and applied to the connecting shaft 30, so that the cradle head 301 connected to the first mounting portion 11 is prevented from shaking, and the shock absorption of the cradle head 301 is realized.

The distribution of the plurality of first supporting members 12 can be set according to actual conditions, so as to optimize the damping effect of the first damping structure 10. For example, the first supporting members 12 may be uniformly distributed around the first mounting portion 11, so that the elastic force resulting from the component forces generated by the plurality of first shock absorbing members 13 is located on the central axis of the connecting shaft 30, thereby better counteracting the vibration of the pan/tilt head 301.

In this embodiment, the number of the first shock absorbing members 13 is equal to the number of the first supporting members 12, and the first shock absorbing members 13 and the first supporting members 12 are correspondingly matched.

The connection mode between the connection rod 121 and the first mounting portion 11 can be set as required to meet different requirements, for example, in one embodiment, the connection rod 121 is movably connected with the first mounting portion 11, so that a user can conveniently adjust the position of the connection rod 121. Wherein, the movable connection can be realized by hinging, sleeving or other movable connection modes.

In another embodiment, the connection rod 121 is fixedly connected to the first mounting portion 11, so as to prevent the connection rod 121 from shaking.

Each connecting rod 121 can be perpendicular to the connecting shaft 30, and the connecting rods 121 are arranged on the same horizontal plane, so that the first damping structure 10 is symmetrical as much as possible, and the vibration of the holder 301 can be better counteracted. Of course, each connecting rod 121 may also be inclined to the connecting shaft 30 (i.e. the connecting rod 121 is not perpendicular to the connecting shaft 30), so that the connecting rods 121 are distributed in different planes.

In addition, the first connecting frame 122 of the present embodiment is integrally provided. Referring to fig. 1, the first connecting frame 122 is provided with a through hole, and the connecting shaft 30 penetrates through the through hole, that is, the first connecting frame 122 is a structure distributed along the circumferential direction of the connecting shaft 30, so that the connecting rod 121, the first shock absorbing member 13 and the first connecting frame 122 are conveniently matched with each other.
