Abstract

The invention discloses a transmission mechanism and relates to the technical field of unmanned aerial vehicles. The transmission mechanism comprises a first shaft and a second shaft, wherein the first shaft is perpendicular to the second shaft in a spaced mode. A driving gear is coaxially and fixedly connected with the first shaft, a transmission gear meshing with the driving gear is coaxially installed on the second shaft, and the transmission mechanism further comprises a third shaft which is arranged in the radial direction of the second shaft. The third shaft is controlled by a control assembly to rotate around the second shaft, and a driven gear meshing with the transmission gear is coaxially installed on the third shaft. By means of the transmission mechanism, the technical problemthat a transmission mechanism in the prior art cannot be partly tilted is solved, the transmission mechanism can quickly tilt under the condition of maintaining norm transmission, and the transmissionmechanism is simple and compact in structure, high in safety and wide in application range, and is little affected by gyroscopic effects.

Description

technical field

[0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a tiltable transmission mechanism and a tilting rotor unmanned aerial vehicle provided with the transmission mechanism. Background technique

[0002] Among UAVs, rotary-wing UAVs can take off and land vertically, but their flight speed is not as good as that of fixed-wing aircraft, and their long-distance flight capabilities are poor. Although fixed-wing UAVs have strong long-distance flight capabilities and fast flight speeds, it takes a long time Based on the advantages and disadvantages of the two, people have produced tilt-rotor UAVs. The rotor orientation of the tilt-rotor UAVs can be tilted, so as to realize the difference between the rotor UAVs and the fixed-wing UAVs. convert.

[0003] The tilting part of the existing tilting-rotor drone is a drive motor, a transmission mechanism and a rotor, and the tilting of the rotor is realized by turning the whole ...
