Problems solved by technology

[0005] In order to overcome the deficiencies in the design of the transmission parts of the flapping-wing aircraft in the prior art, the present invention provides a transmission part of the flapping-wing aircraft based on the Y-shaped structure. During the up and down flapping process of the wings of the flapping wing aircraft, the fluttering is not stable due to the uneven load of the wing main spar, the main wing spar is easily deformed and damaged, and the redundant rotation degree of freedom of the transmission rocker

Embodiment 1

[0050] In a typical implementation of the present application, such as figure 1 , figure 2 , image 3 As shown, a transmission part of a flapping-wing aircraft based on a Y-shaped structure includes a transmission rocker 1. One end of the transmission rocker 1 is arranged in a V shape, and the other end is a spherical bearing I connected with the drive wheel 7. The transmission rocker V Both sides of the type end are provided with a spherical bearing II connected with the wing main spar 10. The transmission part replaces the existing "one"-shaped transmission part through the Y-shaped transmission rocker 1, and the Y-shaped transmission rocker applies force to the wing main spar from both sides of the V-shaped end of the transmission rocker respectively, so that the wing The force on both sides of the main spar is more stable and even, which reduces the damage to the wing main spar 10 and prolongs the service life of the wing main spar 10. Moreover, the plane formed by the...

Embodiment 2

[0061] Such as Image 6 As shown, the difference between this embodiment and Embodiment 1 is: in this embodiment, the transmission rocker is the rib transmission rocker 14, the rib 13 that is rotatably engaged with the wing main spar 10, and the rolling ball III 12 passes through the Z-shaped crank 15 1. The spherical sub-structure is connected to the bottom of the rib transmission rocker 14, and the top of the rib transmission rocker 14 is connected to the rib 13 through a sliding bearing, wherein the plane formed by the two sides of the V-shaped end of the rib transmission rocker 14 and The bottom spherical bearings are arranged on different surfaces, and the angle formed is 90°.

Embodiment 3

[0063] In order to overcome the deficiencies of the prior art, the present invention also provides a flapping-wing structure of a bionic flapping-wing aircraft, including a transmission part of the flapping-wing aircraft based on a Y-shaped structure described in Embodiment 1 or Embodiment 2.

[0064] The transmission structure also includes:

[0065] The drive shaft is provided with a drive wheel at each end;

[0066] The rotating base, the end of the wing main spar is connected with the fuselage main frame through the rotating base, and the wing main spar is rotatably arranged relative to the rotating base.

[0067] There are two rotating bases, which are symmetrically arranged on both sides of the main frame of the fuselage.

[0068] The rotating base is a door frame structure, the rotating base is fixedly connected with the main frame of the fuselage, the rotating pin is arranged in the rotating base, and the end of the main spar of the wing is rotatably engaged with the ...

Abstract

The invention discloses an ornithopter transmission component based on a Y-shaped structure and an implementation method and solves the problems that a slotted transmission component in the prior arthas transmission instability, a main wing beam of a wing is prone to deforming and being damaged, and rotational freedom is redundant. The ornithopter transmission component based on the Y-shaped structure is characterized by comprising a transmission rocker, wherein one end of the transmission rocker is set in a V shape, a first spherical bearing connected with a driving wheel is arranged at theother end of the transmission rocker, second spherical bearings connected with the main wing beam of the wing are arranged on the two sides of the V-shaped end of the transmission rocker, and a structure of the whole transmission component is arranged in a Y shape.

Description

technical field [0001] The invention relates to the mechanical structure field of a bird-like flapping-wing aircraft, in particular to a Y-shaped structure-based transmission part of the flapping-wing aircraft and a realization method. Background technique [0002] The flapping wing aircraft has the advantages of good flexibility, high flapping wing propulsion efficiency, strong maneuverability, light weight, etc., and has great application prospects in both civilian and military fields. The design of the flapping-wing transmission structure is a key issue in the research of flapping-wing aircraft. An efficient and reasonable flapping-wing transmission structure not only needs to conform to the motion laws of birds' flapping wings, but also should ensure that the transmission structure has uniform load, efficient operation, and reliability and stability. [0003] In the prior art, the flapping-wing transmission structure of the flapping-wing aircraft is usually composed of m...
