Embodiment 1

[0037] This embodiment is used for the unmanned aerial vehicle to take off or land under the condition of severe environment and high wind speed.

[0038] Such as figure 2 As shown, the anti-interference UAV device during lifting includes a plurality of auxiliary propellers, and the auxiliary propellers are centered on the cross-shaped frame and symmetrically arranged around the UAV body. The rotation plane of the auxiliary propellers is perpendicular to the horizontal plane, and The direction of rotation plane of the auxiliary propeller is adjustable. There are 4 main propellers on the UAV, namely the first main propeller 1, the second main propeller 2, the third main propeller 3, and the fourth main propeller 4, and the four main propellers are arranged on a cross-shaped frame structure. Considering the arrangement plane of the cross-shaped rack as a Cartesian coordinate plane, the first main propeller 1 and the third main propeller 3 are respectively arranged in the posit...

Embodiment 2

[0045] This embodiment is used in occasions where the UAV takes off and lands in a stable environment.

[0046] Such as image 3 As shown, the anti-interference UAV device during lifting includes a plurality of auxiliary propellers, and the auxiliary propellers are centered on the cross-shaped frame and symmetrically arranged around the UAV body. The rotation plane of the auxiliary propellers is perpendicular to the horizontal plane, and The direction of rotation plane of the auxiliary propeller is adjustable. In this embodiment, the direction of the rotation plane of the auxiliary propeller is adjusted to be parallel to the horizontal plane, which is the same as the direction of the rotation plane of the main propeller. The main propellers include a first main propeller 1, a second main propeller 2, a third main propeller 3, The fourth main propeller 4, and the four main propellers are arranged on the cross-shaped frame structure, and the layout plane of the cross-shaped fra...

Embodiment 3

[0054] This embodiment is used in occasions where the UAV takes off and lands in harsh environments and high wind speeds.

[0055] Such as Figure 4 As shown, the anti-interference UAV device during lifting includes a plurality of auxiliary propellers, and the auxiliary propellers are centered on the cross-shaped frame and symmetrically arranged around the UAV body. The rotation plane of the auxiliary propellers is perpendicular to the horizontal plane, and The direction of rotation plane of the auxiliary propeller is adjustable. The main propellers of the UAV include the first main propeller 1, the second main propeller 2, the third main propeller 3, and the fourth main propeller 4, and the four main propellers are arranged on the cross-shaped frame structure, and the cross-shaped frame The layout plane of the plane is regarded as a Cartesian coordinate plane, then the first main propeller 1 and the third main propeller 3 are respectively arranged in the positive and negativ...

Abstract

The invention discloses the field of unmanned aerial vehicles and provides an unmanned aerial vehicle device ascending and descending smoothly and a control method. The unmanned aerial vehicle device ascending and descending smoothly comprises multiple auxiliary propellers. The auxiliary propellers are symmetrically arranged on the periphery of an unmanned aerial vehicle body with a cross-shaped rack serving as the center. Rotary planes of the auxiliary propellers are perpendicular to the horizontal plane, and the directions of the rotary planes of the auxiliary propellers can be adjusted. By the adoption of the unmanned aerial vehicle device ascending and descending smoothly, the manner that the auxiliary propellers are additionally arranged is adopted, the problem that an unmanned aerial vehicle device deviates due to the interference from the horizontal plane direction is effectively solved, and the unmanned aerial vehicle device ascends and descends smoothly in the vertical direction; and meanwhile the ascending and descending time of the unmanned aerial vehicle device is shortened, the anti-interference ability of the unmanned aerial vehicle in the ascending and descending process in a severe environment is improved, and the problem that the unmanned aerial vehicle deviates and even crushes due to interference is effectively solved.
