[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0051] In recent years, more and more drones have been widely used in various practical lives. Ordinary multi-rotors, helicopters, and fixed-wing aircraft can no longer meet people's needs. Therefore, corresponding tilt-rotor modes superimposed on various types of drones have emerged to better meet people's needs.

[0052] In the prior art, the motor tilting of a tilt-rotor UAV mainly relies on a servo-actuator to directly drive the motor tilting connected to a propeller. However, the servo-actuator that drives the motor tilting is easily affected by the vibration of the UAV and its service life is affected.

[0053] In order to solve at least one of the technical problems existing in the prior art or related art, the utility model provides a lateral tilting mechanism, which is connected to the connecting part through the motor mounting seat, and then the linkage assembly is connected to the driving shaft on the driving part, and the linkage assembly is connected to the connecting part. When the driving part drives the driving shaft to rotate, the linkage assembly drives the driving part to rotate synchronously relative to the connecting part, so that the driving part drives the motor mounting seat connected to the driving part to tilt laterally. Compared with the method in the prior art that the driving part directly drives the tilting of the motor mounting seat, the linkage assembly here can reduce the impact of the vibration of the drone on the driving part, so as to extend the service life of the driving part, thereby extending the service life of the entire lateral tilting mechanism.

[0054] The following describes the lateral tilt mechanism and the UAV according to some embodiments of the utility model with reference to the accompanying drawings.

[0055] See also Figures 1 to 6 A lateral tilt mechanism of an embodiment provided in the first aspect of the utility model is applied to a drone, and the lateral tilt mechanism includes a connecting part 1, a motor mounting seat 2, a driving part 3 and a linkage assembly 4, wherein the connecting part 1 is used to be connected to the arm 5 of the drone; the motor mounting seat 2 is rotationally connected to the connecting part 1; the driving part 3 is connected to the motor mounting seat 2, and the driving part 3 includes a driving shaft; the linkage assembly 4 is connected to the driving shaft, and the linkage assembly 4 is also rotationally connected to the connecting part 1; when the driving part 3 drives the driving shaft to rotate, the linkage assembly 4 is used to drive the driving part 3 to rotate synchronously relative to the connecting part 1.

[0056] It should be noted that see Figure 1 The motor 6 is located above the motor mounting seat 2, the top of the motor 6 is detachably connected to the propeller, and the driving unit 3 is located below the motor mounting seat 2, wherein the driving unit 3 can be a servo steering gear.

[0057] Here, two opposite side portions of the motor mounting seat 2 are rotatably connected to the connecting portion 1 respectively, so that the motor mounting seat 2 can rotate on the connecting portion 1 .

[0058] In this embodiment, the motor mounting seat 2 is connected to the driving part 3 so that the motor mounting seat 2 can move with the driving part 3. At the same time, the linkage assembly 4 is connected to the driving shaft of the driving part 3, and the connecting part 1 is rotationally connected to the linkage assembly 4. Therefore, when the driving part 3 starts the driving shaft to rotate, the linkage assembly 4 moves with the driving shaft, so that the linkage assembly 4 can drive the driving part 3 to rotate synchronously relative to the connecting part 1, and then the driving part 3 drives the motor mounting seat 2 to tilt laterally. In addition, the motor mounting seat 2 and the driving part 3 are connected together and can move synchronously, and the two generate relative movement with the fixed connecting part 1 through the linkage of the driving shaft and the linkage assembly 4. Therefore, compared with the method in the prior art in which the driving part 3 directly drives the tilting of the motor mounting seat 2, the linkage assembly 4 can reduce the influence of the vibration of the drone on the driving part 3, so as to achieve the extension of the service life of the driving part 3, and then extend the service life of the entire lateral tilting mechanism.

[0059] In some possible embodiments, the linkage assembly 4 includes a first connecting rod 401 and a second connecting rod 402, wherein the first end of the first connecting rod 401 is connected to the drive shaft; the first end of the second connecting rod 402 is hinged to the second end of the first connecting rod 401, and the second end of the second connecting rod 402 is hinged to the connecting part 1.

[0060] When the driving unit 3 controls the driving shaft to rotate, the first connecting rod 401 moves with the rotation of the driving shaft to drive the second connecting rod 402 hinged to its second end to rotate synchronously, thereby causing the second end of the second connecting rod 402 to rotate relative to the connecting part 1, changing the position of the second connecting rod 402 between the first connecting rod 401 and the connecting part 1, and realizing the rotation of the driving unit 3 relative to the connecting part 1 through the cooperation of the first connecting rod 401 and the second connecting rod 402, thereby realizing the rotation of the motor mounting seat 2 relative to the connecting part 1 driven by the driving unit 3.

At the same time, the first connecting rod 401, the second connecting rod 402, the connecting part 1 and the third connecting rod 403 can form a four-bar transmission mechanism, which can better reduce the influence of the vibration generated by the motor's own height during its rotation on the life of the driving part 3.

The fastening part 404 can be a bolt.

[0066] In this embodiment, a first tooth-shaped groove is provided on the outer peripheral side of the connecting disk, and a second tooth-shaped groove is provided on the inner side wall of the first connecting hole opened on the first connecting rod 401, so that after the first connecting hole is mounted on the connecting disk, the second tooth-shaped groove is engaged with the first tooth-shaped groove to realize the fixed connection of the first connecting rod 401 on the driving shaft; and then the first end of the first connecting rod 401 is fixed to the driving shaft by using the fastening part 404 to realize a more stable fixed connection between the first connecting rod 401 and the driving shaft.

[0067] In some possible embodiments, the first end and the second end of the second connecting rod 402 are both rotatably connected with the second end of the first connecting rod 401 and the connecting part 1 through a second connecting assembly, and the second connecting assembly includes a second connecting hole, a bearing assembly 405 and a pin shaft portion 406.

A bearing assembly 405 is provided in each of the two second connecting holes, so that a pin shaft portion 406 passes through the bearing assembly 405 at the first end of the second connecting rod 402 and is matched with the first connecting rod 401 to achieve a rotational connection between the first end of the second connecting rod 402 and the first connecting rod 401; and another pin shaft portion 406 passes through the connecting plate 101 on the connecting portion 1 and is matched with the bearing assembly 405 at the second end of the second connecting rod 402 to achieve a rotational connection between the second end of the second connecting rod 402 and the connecting portion 1.
