Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the embodiments of the present disclosure, where the contrary is not stated, the use of directional words such as "inner" and "outer" is directed to the inherent contours of the respective parts; the longitudinal direction and the transverse direction of the unmanned aerial vehicle are defined by taking the normal flat flying state of the unmanned aerial vehicle as a reference, specifically, the front-back direction of the unmanned aerial vehicle is the longitudinal direction, and the left-right direction of the unmanned aerial vehicle is the transverse direction; the terms "first" and "second" used in the embodiments of the present disclosure are intended to distinguish one element from another, and are not necessarily sequential or significant; further, in the following description, when referring to the figures, the same reference numbers in different figures denote the same or similar elements.

As shown in fig. 1 and fig. 2, the unmanned aerial vehicle tilting mechanism provided by the embodiment of the present disclosure includes a tilting steering engine 10, a steering engine mount 20, and a motor mount 30. The steering engine seat 20 is used for mounting the tilting steering engine 10; the motor mount 30 is used for mounting the rotor 40 shown in fig. 5 and 6 and a motor 50 capable of driving the rotor 40 to rotate, and the motor mount 30 is rotatably connected to the rudder mount 20 by a first rotating shaft 31. In the embodiment of the present disclosure, the tilt steering engine 10 is configured to drive the motor base 30 to rotate, and an output shaft of the tilt steering engine 10 is coaxial with the first rotating shaft 31. That is, the output shaft of the tilt steering engine 10 drives the motor base 30 to rotate around the output shaft and the first rotating shaft 31, and the rotor 40 and the motor 50 mounted on the motor base 30 can rotate together with the motor base 30, thereby achieving tilt. In this way, the vibration load of the rotor 40 and the motor 50 during operation and the gyro moment generated during tilting not only act on the output shaft of the tilting steering engine 10 through the motor base 30, but also act on the rudder base 20, that is, the rudder base 20 can bear part of the vibration load and the gyro moment, thereby prolonging the service life of the tilting steering engine 10 and improving the control and output accuracy.

The structure of the steering engine base 20, the structure of the motor base 30 and the form of the driving motor base 30 of the tilting steering engine 10 are not particularly limited in the embodiment of the disclosure, as long as the vibration load and the gyro moment transmitted by the motor base 30 can be borne by the steering engine base 20, and the following description is only provided for some embodiments with reference to the accompanying drawings.

Referring to fig. 3, an output shaft of the tilt steering engine 10 may be connected to a rocker arm 11, and a motor base 30 is fixedly connected to the rocker arm 11. In this case, the motor base 30 is not directly connected to the output shaft of the tilt steering engine 10, and the vibration load and the gyro moment described above are not directly transmitted to the output shaft, thereby further increasing the service life of the tilt steering engine 10. In addition, in the present embodiment, the motor base 30 is connected to the rudder base 20 through the first rotating shaft 31, and the output shaft of the tilt steering engine 10 is not directly connected to the motor base 30, so that the problem of interference between the output shaft and the first rotating shaft 31 during arrangement is avoided.
