[0046] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0047] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0048] Please refer to Figure 1 A gimbal 1000 is provided for one of the embodiments of the present application, which is used for shock absorption of a UAV. The gimbal 1000 comprises a shock absorption device 100 and a mount 200, the mount 200 is installed on the shock absorption device 100, and the mount 200 is used for installing a camera device.

[0049] The shock absorption device in the prior art realizes shock absorption by arranging four shock absorption balls at the four corner points of a rectangle, which cannot take into account any direction and is easy to overload the mount in a certain direction, affecting the stability of the gimbal and the UAV. In order to reduce the shock of the mount during the operation of the UAV in any direction as much as possible and improve the stability of the gimbal and the UAV, the present application provides a new shock absorption device, which will be described in detail below.

[0050] Please refer to Figure 2The damping device 100 comprises a first fixed plate 10, a second fixed plate 20 arranged in parallel and spaced apart on one side of the first fixed plate 11, a first damping mechanism 30 mounted between the first fixed plate and the second fixed plate, and a second damping mechanism 40 mounted in the first damping mechanism 30. The damping device 100 can first attenuate most of the vibration of the unmanned aerial vehicle through the first damping mechanism 30, and the remaining vibration is eliminated by the second damping mechanism 40, achieving better damping effect.

[0051] Please refer to Figure 3 In the embodiment of the present application, the first fixed plate 10 is a circular plate structure, and a plurality of lightening grooves 11 are uniformly and spaced apart arranged on the first fixed plate 10, which is beneficial to realize the lightness of the damping device 100 and avoid affecting the flight quality of the unmanned aerial vehicle due to the excessive weight of the damping device 100.

[0052] It can be understood that in other embodiments, the first fixed plate 10 can also be other structures, for example, a square structure, etc. The first fixed plate 10 is designed as a circular structure in the present application in order to cooperate with the damping mechanism and as far as possible to reduce the weight of the first fixed plate 10.

[0053] The second fixed plate 20 is mounted on the unmanned aerial vehicle to carry the gimbal 1000 on the unmanned aerial vehicle, so that the damping device 100 damps the unmanned aerial vehicle.

[0057] It can be understood that in other embodiments, the first buffer portion can also be other shapes, for example, a wavy line, etc., but the present application considers that the mounting 200 is relatively heavy, and the thickness of the buffer portion of the arc-shaped structure is thicker than that of the wavy-shaped buffer portion, which can bear greater weight, therefore, the buffer portion of the arc-shaped structure is more suitable than the wavy-shaped buffer portion.

[0058] In some embodiments, the first elastic member 31 is made of a flexible material, such as rubber.

[0059] The first damping mechanism 30 further comprises a first fixing ring 32 and a second fixing ring 33.

[0061] In some embodiments, the first damping mechanism 30 further comprises a first fastener and a second fastener (not shown). A plurality of first fixing holes 3112 are arranged on the first mounting portion 311 at intervals along the outer circumference, and the first fixing holes 3112 and the first positioning holes 3111 are arranged alternately.

[0064] In some embodiments, the second buffer portion 413 is in an arc shape, and the second buffer portion 413 extends away from the first buffer portion 313, that is, the second buffer portion 413 extends toward a hollow part of the second elastic member 41.

[0065] It can be understood that, in other embodiments, the second buffer portion can also be in other shapes, such as a wave shape, but the application considers that the hanging device 200 is relatively heavy, and the buffer portion in the arc shape is thicker than the buffer portion in the wave shape, and can bear a greater weight. Therefore, the buffer portion in the arc shape is more suitable than the buffer portion in the wave shape.

[0066] In some embodiments, the second elastic member 32 is made of a flexible material, such as rubber.

[0067] In some embodiments, the second damping mechanism 40 further includes a third fixed ring 42 and a fourth fixed ring 43. The third mounting portion 411 is fixed to the first fixed plate 10 through the third fixed ring 42, and the fourth mounting portion 412 is fixed to the second fixed plate 20 through the fourth fixed ring 43.

[0073] Please refer to Figure 7 In some embodiments, the mount 200 is arranged in the second damping mechanism 40, one end of the mount 200 is mounted to the first fixing plate 10, and the other end of the mount 200 extends out of the second fixing plate 20.

[0074] Since the cross section of the first elastic member 31 and the second elastic member 41 along the x direction is circular, the resistance and elastic force borne by the mount 200 during the flight of the unmanned aerial vehicle are uniformly distributed on the circumference, so that the mount 200 will not be overloaded in a certain direction, and the stability of the gimbal and the unmanned aerial vehicle is improved.
