Background

Unmanned aerial vehicle realizes the nimble adjustment of shooting ranges such as horizontal angle, every single move angle, roll angle of shooting ware through self rotation or aversion, has been used for the field of taking photo by plane at present in particular. Because the influence of wind power and unmanned aerial vehicle self vibrations in the in-process of taking photo by plane, the cloud platform often takes place vibrations and arouses the shooting ware to take place the shake to influence the shooting effect.

In order to improve the imaging effect, the cloud platform that unmanned aerial vehicle carried need add the shock attenuation design in order to form and increase steady cloud platform. The common damping mode of the stability-increasing cradle head is that a damping ball is used for isolating vibration above the cradle head, so that high-frequency vibration can be effectively attenuated. The structure of the existing damping mechanism is relatively complex, and at least three damping ball setting points are generally arranged between an aircraft and a holder. Further, the vibration transmitted to the pan/tilt head by the aircraft is reduced by increasing the number of the damping balls at the damping ball set point.

Fig. 1 shows an unmanned aerial vehicle of the prior art, with a shock absorber disposed between the fuselage of the unmanned aerial vehicle and the pan/tilt head. Four shock attenuation ball 20 overall arrangement are on a horizontal plane and the centroid of shock attenuation ball overall arrangement roughly lie in cloud platform top surface place horizontal plane or near, because the distance far away that shock attenuation ball overall arrangement centroid and cloud platform's focus are apart from, horizontal vibration when unmanned aerial vehicle translation can cause the cloud platform to rotate around the focus and produce the coupling of vibration, brings very big external disturbance, has serious harmful effects to the control effect of cloud platform.

The four damping balls 20 are arranged on the same inclined plane inclined relative to the horizontal plane on which the top surface of the holder is located, the centroid 300 of the arrangement of the damping balls is located below the horizontal plane on which the top surface of the holder is located, and compared with the example that the centroid shown in fig. 1 is located on the top surface of the holder, the distance between the centroid 300 of the arrangement of the damping balls and the gravity 400 of the holder is reduced, so that the stability augmentation control effect on the holder is improved to a certain extent. However, this kind of damping mechanism requires that the damping balls be located on the same inclined plane, and has a high demand on the arrangement position of the damping balls, and layout is not flexible enough, and also makes the structure of the connection structure more complicated and more limited.

Most of the shock attenuation schemes are realized with rubber shock attenuation ball at present to the effect of shock attenuation is realized to the overall arrangement of multiple different shock attenuation ball. In the conventional damping scheme, the geometric centers of a plurality of damping balls are generally required to be positioned on the same horizontal plane or the same inclined plane, and the limitation is too large.

Detailed Description

Exemplary embodiments will be described in detail below. The following description refers to the accompanying drawings, in which like reference numerals refer to the same or similar elements in different drawings unless otherwise specified. The following exemplary embodiments are intended to be illustrative only and are not intended to limit the scope of the present invention.

Fig. 3 and 4 show a perspective view and a side view, respectively, of a pan and tilt head shock absorber 1 according to a first embodiment of the present invention. Cloud platform bumper shock absorber 1 sets up on unmanned aerial vehicle's cloud platform 2, the cloud platform is including shooing ware 3 and being used for bearing the bracket component 4 of shooing the ware. Cloud platform bumper shock absorber 1 through coupling assembling 5 with cloud platform 2 is connected, the cloud platform passes through cloud platform bumper shock absorber is connected with unmanned aerial vehicle's fuselage. The head shock absorber comprises five shock absorbing units D1, D2, D3, D4, D5, the geometric centres of which are arranged as a spatial polyhedron, the centroid S of which is close to, and possibly even coincident with, the centre of gravity G of the head (see fig. 4).

As shown in fig. 3, the connecting assembly 5 includes a main body portion 10 disposed on the top surface of the pan/tilt head and five arms extending from the main body portion. These five arms include: a first arm 11 and a second arm 12 (see fig. 5) extending below a horizontal plane on which the center of gravity of the head is located; and the shock absorption units D1, D2, D3, D4 and D5 are respectively arranged on the first arm 11, the second arm 12, the third arm 13, the fourth arm 14 and the fifth arm 15.

The first and second arms 11 and 12 extend rearward from the main body 10 by a distance and then vertically downward by a distance such that the shock-absorbing units D1 and D2 are located rearward and downward with respect to the main body 10. This arrangement of the first arm 11 and the second arm 12 can be arranged relatively snugly around the bracket assembly 4 (see fig. 4), resulting in a flat appearance and space saving.

Preferably, the first arm 11 and the second arm 12 are symmetrically arranged with respect to a longitudinal centerline of the main body portion 10.

As shown in fig. 3, the third arm 13, the fourth arm 14, and the fifth arm 15 are located on the same horizontal plane. The third arm 13 extends forward relative to the main body 10, and the fourth arm 14 and the fifth arm 15 extend laterally symmetrically relative to the main body 10. The symmetrical arrangement can ensure that all the damping units are stressed uniformly, and can prevent the damping units from generating severe changes of stress or even change of stress directions when the whole unmanned aerial vehicle flies in a maneuvering manner, so that the damping units meet the requirements of rigidity and damping linear stages. The first arm 11, the second arm 12, the third arm 13, the fourth arm 14 and the fifth arm 15 and the shock-absorbing units thereon are symmetrically arranged with respect to the longitudinal centerline of the main body 10, thereby optimizing the control of shock-absorbing stability and contributing to the simplification of the manufacturing process of the connecting assembly.

This arrangement, shown in figure 3, makes the connection assembly 5 simple and symmetrical in construction and easier to manufacture and install. Moreover, this arrangement provides the connecting assembly with a spatial pentahedral layout for five damping units. The centroid S of the spatial pentahedron is located on the vertical line of the center of gravity G of the pan/tilt head, above the center of gravity of the pan/tilt head and below the top face of the pan/tilt head (see fig. 4).

Compared with the shock absorber in the prior art shown in fig. 1, the centroid of the pentahedral layout of the shock absorber is greatly lower than the top surface of the pan-tilt, so that the vibration caused by yaw, transverse roll or pitch motion of the unmanned aerial vehicle can be reduced, and the vibration isolation effect is improved. Moreover, the layout of the spatial polyhedron enables the available space on the tripod head to be fully utilized so as to enable the arrangement of each damping unit to be more flexible, and each damping unit does not need to be arranged in the same horizontal plane above the top surface of the tripod head.

Compared with the shock absorber in the prior art shown in fig. 2, the centroid of the layout of the pentahedron of the shock absorber can be adjusted to enable the centroid S of the space pentahedron to be close to the vertical line where the gravity G of the holder is located or to coincide with the gravity G, so that the vibration caused by the yaw motion of the unmanned aerial vehicle can be greatly reduced, and the vibration isolation effect is improved. Moreover, the layout of the spatial polyhedron makes it possible to make full use of the available space on the head to make the setting of the damping units more flexible, without having to set the damping units in the same inclined plane.

It is clear that the shock absorber arrangement shown in fig. 3 does not disturb the normal operation of the camera and provides it with an improved stability augmentation effect.

Alternatively, the first and second arms 11 and 12 may extend vertically downward from the main body portion 10 by a distance and then extend obliquely rearward by a distance such that the shock-absorbing units D1 and D2 are located rearwardly downward with respect to the main body portion 10. The arrangement of the first arm 11 and the second arm 12 may be arranged relatively snugly around the bracket assembly 4, depending on the actual situation.

Alternatively, where the installation space allows, the first arm 11 and the second arm 12 may extend obliquely rearward and downward from the main body portion 10 by a distance such that the shock-absorbing units D1 and D2 are located rearward and downward with respect to the main body portion and below the horizontal plane on which the center of gravity of the pan/tilt head is located. Such an arrangement may make the connection assembly simple in construction and easy to manufacture, but increase the installation space.

Fig. 6 and 7 show a perspective view and a side view, respectively, of a pan head shock absorber according to a second embodiment of the present invention. Similar to the first embodiment shown in fig. 3, except that the third arm 13 is located at a different level with respect to the fourth arm 14 and the fifth arm 15. Fig. 6 shows the third arm 13 positioned below with respect to the fourth arm 14 and the fifth arm 15.

As shown in fig. 6, the third arm 13 extends vertically downward from the main body portion 10 by a distance and then horizontally forward by a distance so that the shock-absorbing unit D3 is located forward and downward with respect to the main body portion 10. Alternatively, the third arm 13 extends horizontally forward from the main body portion 10 by a distance and then vertically downward by a distance so that the shock-absorbing unit D3 is located forward and downward with respect to the main body portion 10. By lowering the height of the shock absorbing unit D3 by changing the extending direction of the third arm 13 of the connecting assembly 5, it is easier to make the centroid of the space polyhedron coincide with the center of gravity of the pan/tilt head. In this case, the vibration caused by the yaw, lateral roll or pitch motion of the unmanned aerial vehicle can be greatly reduced, so that the optimal damping and stabilizing effects are provided. This arrangement of the third arm 13 can be disposed around the bracket assembly 4 in a more fitting manner as the case may be, thereby achieving the effects of leveling the appearance and saving space.

Alternatively, the third arm 13 may be inclined and extended from the main body portion 10 directly downward and forward by a distance such that the shock-absorbing unit D3 is positioned downward and forward with respect to the main body portion, where the installation space allows. This arrangement of the third arm 13 may make the connecting assembly simple in structure and easy to manufacture, but increase the installation space.

Alternatively, the third arm 13 extends horizontally a distance forward from the main body 10, and the fourth and fifth arms 14, 15 extend laterally a distance relative to the main body 10 and then extend a distance downward. At this time, the fourth arm 14 and the fifth arm 15 may be located downward with respect to the third arm 13.

Fig. 8 and 9 show a perspective view and a side view, respectively, of a pan head shock absorber according to a third embodiment of the present invention. As shown in fig. 7, four shock-absorbing units D1, D2, D3 and D4 are provided, thereby providing a spatial tetrahedral layout of the pan and tilt head shock absorber. The first arm 11 and the second arm 12 are arranged symmetrically downward in the lateral direction with respect to the main body portion 10, and the third arm 13 and the fourth arm 14 are arranged back and forth in the longitudinal direction with respect to the main body portion 10. The shock-absorbing units D1, D2, D3 and D4 are in the form of shock-absorbing blocks.

Such a layout of the head shock absorbers as shown in fig. 7 and 8 makes it easier to make the centroid S of the spatial polyhedron coincide with the center of gravity G of the head. Moreover, the arrangement makes the connecting assembly simpler in structure.

Alternatively, a spatial tetrahedral layout comprising four damping units may be achieved by omitting one of the five damping units in the first and second embodiments. For example, in comparison to the layout shown in fig. 3, the fifth arm 15 and the shock-absorbing unit D5 provided thereon are omitted, and the four shock-absorbing units D1, D2, D3 and D4 provide a spatial tetrahedral layout. The centroid S of the space polyhedron is positioned on the right side of a vertical line where the gravity G of the holder is positioned, is positioned above the gravity G of the holder and is positioned below the top surface of the holder. Alternatively, the fifth arm 15 may be left without providing the shock absorbing unit D5 on the fifth arm 15, and the four shock absorbing units D1, D2, D3 and D4 provide a spatial tetrahedral layout. The centroid S of the space polyhedron is also positioned on the right side of the vertical line where the gravity G of the holder is positioned, positioned above the gravity G of the holder and positioned below the top surface of the holder. Also, any of the five damping units may be omitted such that the remaining four damping units constitute a spatial tetrahedral layout. The centroid S of said spatial tetrahedron is also offset from the vertical line on which the centre of gravity G of the head lies (i.e. in the vicinity of the vertical line on which the centre of gravity G of the head lies), but is located above the centre of gravity of the head and below the top face of the head.

Fig. 10 shows a perspective view of a pan and tilt head shock absorber according to a fourth embodiment of the present invention. Similar to the first embodiment shown in fig. 3, the third arm 13, the fourth arm 14 and the fifth arm 15 are located on the same horizontal plane, except that the arrangement of the first arm to the fifth arm is changed correspondingly because the structure of the main body portion 10 is rectangular.

Fig. 11 shows a perspective view of a pan and tilt head shock absorber according to a fifth embodiment of the present invention. Similar to the second embodiment shown in fig. 6, the third arm 13 is located on a different level with respect to the fourth arm 14 and the fifth arm 15, except that the arrangement of the first to fifth arms varies correspondingly due to the rectangular configuration of the main body 10.

The spatial tetrahedral layout of the four shock-absorbing units D1, D2, D3 and D4 shortens the distance between the centroid S of the spatial polyhedron and the center of gravity G of the pan/tilt head, so that there is an improved shock-absorbing and stability-increasing effect with respect to the shock-absorbing unit layout shown in fig. 1.

Other arrangements of the arms of the connecting assembly 5 may also be provided, provided that the centroid of the spatial polyhedron formed by the at least four damping units is close to the center of gravity of the head.

The utility model discloses cloud platform bumper shock absorber can include the shock attenuation unit more than four. For example, four, five, six or more, as long as the centroids of the spatial polyhedrons (tetrahedrons, pentahedrons, hexahedrons, etc.) they constitute are close to the center of gravity of the head. Preferably, the centroid S of the spatial polyhedron (tetrahedron, pentahedron, hexahedron, etc.) coincides with the center of gravity G of the head.

The shock-absorbing unit may include a shock-absorbing body having a spherical shape, a cylindrical shape, a truncated conical shape, a regular polyhedral shape, or other shapes. The damping unit is made of soft materials such as silica gel rubber and the like, and can effectively damp high-frequency vibration. Preferably, the damping unit is in the form of a damping ball.

Each damping unit may include an appropriate number of damping bodies (e.g., one, two, or more) depending on the particular available space or desired centroid position adjustment, which is a high number of damping bodies that provide good damping but add weight and are limited by the available space. The shape and/or size of the dampers can be the same to better maintain structural symmetry. Alternatively, the shape and/or size of the shock absorbers may be different to accommodate the particular available space.

The utility model also provides an unmanned aerial vehicle cloud platform, unmanned aerial vehicle cloud platform is equipped with as before cloud platform bumper shock absorber. Preferably, the pan-tilt is a three-axis pan-tilt, the bracket assembly includes a yaw axis assembly connected to the connection assembly, a roll axis assembly movably connected to the yaw axis assembly, and a pitch axis assembly movably connected to the roll axis assembly, and the camera is carried on the pitch axis assembly.

The utility model also provides an unmanned aerial vehicle, this unmanned aerial vehicle include the fuselage and as before the cloud platform.

Because the shock absorption unit of above-mentioned bumper shock absorber sets up in a flexible way and provides good shock attenuation and increase steady effect, unmanned aerial vehicle cloud platform and unmanned aerial vehicle obtain good stationarity, accomplish its set task better.

The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Many variations and modifications may be made by those skilled in the art in light of the teachings of the present invention without departing from its scope. Features of different embodiments may be used in combination with or instead of features of another embodiment within the scope of the inventive concept.
