Technical Field

[0001] The utility model relates to the technical field of bionic aircraft, in particular to a bionic butterfly aircraft. Background Art

[0002] With the continuous advancement of science and technology and the in-depth exploration of nature by humans, bionics as an interdisciplinary research field has attracted increasing attention. In this field, the bionic butterfly is a fascinating case that shows the fascination and exploration of humans for the complex and ingenious designs of nature. The bionic butterfly is not just a simple imitation of the appearance of a butterfly, but also the design and manufacture of an artificial device or system with a butterfly-like appearance, structure or function through biological principles and engineering technology.

[0003] In terms of basic biological research, scientists have revealed the unique biological characteristics of butterflies, such as wing structure, flight mechanism and perception ability, through the study of butterfly anatomy, physiology and behavior. These studies provide valuable reference and inspiration for the design and application of bionic butterflies.

[0004] In the field of art and design, the beautiful shape and unique colors of butterflies also provide artists with rich creative inspiration. Artworks reinterpret the shape, color and texture of butterflies to present unique visual effects and explore the perfect combination of nature and art.

Through the research and application of bionic butterflies, humans can not only understand the mysteries of nature more deeply, but also promote the innovative development of science and technology and art, and contribute to the progress of human society.

[0006] In some existing bionic butterfly structures, such as the Chinese utility model patent with patent number: 201610260698.X, a new type of bionic butterfly aircraft with independent double-wing drive is disclosed, which is composed of a main trunk, a wing assembly, a micro-control system, and a power supply system. The wing assembly includes a left wing assembly and a right wing assembly, which have the same structural and dimensional parameters. The servo motors therein are symmetrically installed on the left and right sides of the main trunk, and the servo motors are used to control the flapping action of the left and right wings of the bionic butterfly aircraft to generate lift and thrust. Since the left and right wing assemblies of the bionic butterfly are independently driven, it is necessary to independently control the flapping frequency, amplitude, and initial and final phases of the wings on both sides when completing pitch, yaw and other actions. It is impossible to yaw quickly in a high-speed flight state, and the flexibility of use is low. Utility Model Content

[0007] Therefore, it is necessary to provide a bionic butterfly aircraft to solve the problem of low flexibility in the use of independent driving of the left wing assembly and the right wing assembly of the existing bionic butterfly.

[0008] To achieve the above-mentioned purpose, the inventor provides a bionic butterfly aircraft, comprising: a main rod, flapping wings, a tail wing, a flapping wing drive assembly and a tail wing drive assembly.

[0009] The flapping-wing driving assembly comprises a driving motor, a driving gear, a first crank gear and a second crank gear, wherein the driving gear is connected to the output shaft of the driving motor, and the driving motor drives the second crank gear to rotate by meshing with the first crank gear, the first crank gear is connected to a first swing arm via a first rocker eccentrically connected thereto, and the second crank gear is connected to a second swing arm via a second rocker eccentrically connected thereto, the first swing arm and the second swing arm are arranged in parallel and sleeved on the front end of the main rod, and are respectively connected to both sides of the front end of the flapping wing;

[0010] The tail driving assembly includes a steering gear and a swinging part, the steering gear is sleeved on the middle part of the main rod through a steering gear fixing piece, and the steering gear fixing piece is clamped on the rear end of the flapping wing, the swinging part is connected to the output end of the steering gear, the middle part of the tail wing is provided with a tail wing fixing hole for penetrating the main rod, the front end of the tail wing is connected to the swinging part, and the steering gear drives the tail wing to swing when working;

[0011] The tail wing is arranged obliquely with respect to the main rod, and the front end of the tail wing is arranged below the main rod.

[0012] Furthermore, the angle between the tail wing and the main rod ranges from 40° to 45°.

[0013] Furthermore, the upper portion of the servo fixing piece is a hook-shaped structure, a flapping-wing fixing hole is provided at the rear end of the flapping wing, and the hook-shaped structure is clamped in the flapping-wing fixing hole.

[0014] Furthermore, flapping wing connecting holes for the first swing arm and the second swing arm to penetrate are arranged on both sides of the front end of the flapping wing.

[0015] Furthermore, the bionic butterfly aircraft also includes a flexible fixing ring, which is connected below the flapping wing and the tail wing.

[0016] Furthermore, the tail wing fixing hole is an elongated strip structure, and an extending direction of the elongated strip structure is the same as an extending direction of the swinging portion.

[0017] Furthermore, the flapping wing is a one-piece structure.

[0018] Furthermore, two tail wing frames are arranged below the tail wing and are symmetrically arranged along the main rod.

[0057] See also Figures 1 to 6 The present embodiment is a bionic butterfly aircraft, comprising: a main rod 1, flapping wings 2, a tail wing 3, a flapping wing drive assembly 4 and a tail wing 3 drive assembly,

[0058] The flapping-wing driving assembly 4 includes a driving motor 41, a driving gear, a first crank gear 42 and a second crank gear 43, wherein the driving gear is connected to the output shaft of the driving motor 41, and the driving motor 41 drives the second crank gear 43 to rotate by meshing with the first crank gear 42, the first crank gear 42 is connected to a first swing arm 451 through a first rocker 441 eccentrically connected thereto, and the second crank gear 43 is connected to a second swing arm 452 through a second rocker 442 eccentrically connected thereto, the first swing arm 451 and the second swing arm 452 are arranged in parallel and sleeved on the front end of the main rod 1, and are respectively connected to both sides of the front end of the flapping wing 2;

[0059] The tail wing 3 driving assembly includes a steering gear 51 and a swinging part 52. The steering gear 51 is sleeved on the middle part of the main rod 1 through a steering gear fixing part 511, and the steering gear fixing part 511 is clamped on the rear end of the flapping wing 2. The swinging part 52 is connected to the output end of the steering gear 51. The middle part of the tail wing 3 is provided with a tail wing fixing hole 31 for penetrating the main rod 1. The front end of the tail wing 3 is connected to the swinging part 52. The steering gear 51 drives the tail wing 3 to swing when it works.

[0060] The tail wing 3 is arranged obliquely with respect to the main pole 1 , and the front end of the tail wing 3 is arranged below the main pole 1 .

[0061] The main rod 1 is the main body of the aircraft, providing support and connecting other components. The flapping wings 2 are located on both sides of the front end of the main rod 1, which are used to simulate the flapping of butterfly wings to achieve the lifting and stability control of the aircraft. The tail 3 is located at the rear end of the main rod 1, which is used to provide attitude control and stability of the aircraft.

[0062] During the flight of the bionic butterfly aircraft, the flapping wings 2 flap on both sides to fly, and the tail wing 3 swings to complete the yaw action of the aircraft, that is, the flying and yaw are independently completed by the flapping wings 2 and the tail wing 3. Even during the high-speed flight of the bionic butterfly aircraft, the yaw can still be flexibly achieved, and the specific yaw includes turning, pitching, etc.

[0063] The first crank gear 42 and the second crank gear 43 are arranged in parallel, and the eccentric position of the first rocker arm 441 on the first crank gear 42 corresponds to the eccentric position of the second rocker arm 442 on the second crank gear 43, so that when the first crank gear 42 and the second crank gear 43 respectively drive the first rocker arm 441 and the second rocker arm 442, the swing amplitudes of the first rocker arm 441 and the second rocker arm 442 are equivalent, so that the bionic butterfly aircraft can fly smoothly.

[0064] The driving gear includes a primary driving gear 461, a secondary driving gear 462 and a tertiary driving gear 463. The primary driving gear 461 is meshed with the secondary driving gear 462. The tertiary driving gear 463 is coaxially arranged with the secondary driving gear 462. The number of teeth of the primary driving gear 461 and the number of teeth of the tertiary driving gear 463 are both much smaller than the number of teeth of the secondary driving gear 462. The primary driving gear 461 is drivingly connected to the output shaft of the driving motor 41, and transmits power to the tertiary driving gear 463 through the secondary driving gear 462 meshed therewith, and speed reduction is achieved through the gear ratio between the primary driving gear 461 and the secondary driving gear 462. The three-stage driving gear 463 is meshed with the first crank gear 42. The rotation of the three-stage driving gear 463 can drive the first crank gear 42 to rotate. The meshing of the first crank gear 42 and the second crank gear 43 drives the second crank gear 43 to rotate. The first crank gear 42 and the second crank gear 43 rotate synchronously to make the first rocker arm 441 and the second rocker arm 442 swing synchronously, so that the first swing arm 451 and the second swing arm 452 swing on both sides of the flapping wing 2.

[0065] In this embodiment, the central axis directions of the primary drive gear 461 , the secondary drive gear 462 , the tertiary drive gear 463 , the first crank gear 42 and the second crank gear 43 are the same as the extension direction of the main shaft.

[0066] The flapping wings 2 are evenly distributed on both sides of the main rod 1. In order to better fix the flapping wings 2, the first swing arm 451 and the second swing arm 452 are provided with a certain length, and the first swing arm 451 and the second swing arm 452 extend to the edge of the flapping wings 2 for fixing them.

[0067] The tail 3 and the main rod 1 are tilted so that the tail 3 and the extension direction of the flapping wing 2 are set at a certain angle, which facilitates the airflow to provide lift to the bionic butterfly aircraft when passing through the tail 3, so as to provide better stability and attitude control.

[0068] The steering gear 51 is arranged in the middle of the main rod 1 to balance the weight of the flapping-wing drive assembly 4 arranged at the front end of the main rod 1, so as to prevent the bionic butterfly aircraft from being top-heavy and obtain a better balance effect. The heavy driving motor 41 and the steering gear 51 are arranged below the main rod 1, so that their gravity is located in the middle of the main rod 1, so that the bionic butterfly aircraft is more stable during flight.

[0069] Driven by the steering gear 51, the swinging member will swing left and right around the output shaft of the steering gear 51, and the direction of the output shaft of the steering gear 51 is the same as the extension direction of the main shaft. When the steering gear 51 is working, it drives the tail 3 to swing, so as to adjust the attitude of the aircraft. The swinging part 52 has a certain rigidity. During the swinging process, the tail 3 will tilt to one side driven by the swinging part 52, so that the airflow passing through the tail 3 changes, thereby realizing the yaw motion of the bionic butterfly aircraft.

[0070] The flapping wing drive assembly 4 and the tail wing 3 drive assembly of the bionic butterfly aircraft provided in this embodiment can respectively control the movement of the flapping wing 2 and the tail wing 3, so as to realize the lifting, stabilization and attitude adjustment of the aircraft. Through reasonable design and control, the aircraft can simulate the flight action of a butterfly and has good maneuverability and stability.

[0071] In some embodiments, the angle between the tail wing 3 and the main pole 1 is in the range of 40-45 degrees.

[0072] In some embodiments, the upper portion of the servo fixing member 511 is a hook-shaped structure, and a flapping wing fixing hole 21 is provided at the rear end of the flapping wing 2, and the hook-shaped structure is clamped in the flapping wing fixing hole 21. The rear end of the flapping wing 2 is fixed by the servo fixing member 511, so that the flapping wing 2 is fixed on the main rod 1 and the flapping wing drive assembly 4 in a triangular shape, which can prevent the rear end of the flapping wing 2 from swinging in the air during the movement, thereby increasing the flight resistance.

[0073] In some embodiments, both sides of the front end of the flapping wing 2 are provided with flapping wing 2 connection holes for the first swing arm 451 and the second swing arm 452 to penetrate. The flapping wing 2 is fixed to the flapping wing drive assembly 4 and the main rod 1 in a detachable connection manner. The flapping wing 2 may be damaged or worn out after frequent use. After the flapping wing 2 is detachably fixed to the flapping wing drive assembly 4 and the main rod 1, it is convenient to replace the flapping wing 2.

[0074] In some embodiments, the bionic butterfly aircraft further comprises a flexible fixing ring, which is connected below the flapping wing 2 and the tail wing 3. The flexible fixing ring can be generally made of materials such as PVC or PP. The role of the flexible fixing ring is to increase the stability and flexibility of the aircraft, and can provide flexible support so that the flapping wing 2 and the tail wing 3 can swing freely and adapt to different flight states during flight. Such a design can improve the maneuverability and adaptability of the aircraft, making the bionic butterfly aircraft more suitable for performing various flight missions.

[0075] In some embodiments, the tail fixing hole 31 is a long strip structure, and the extension direction of the long strip structure is the same as the extension direction of the swinging portion 52. This design can ensure that the tail 3 can move smoothly when swinging, and the attitude and stability of the aircraft can be changed by adjusting the position of the tail 3 in the fixing hole. The fixing hole of the long strip structure can also provide a larger adjustment range, making the attitude control of the aircraft more flexible and accurate.

[0076] In some embodiments, the flapping wing 2 is a one-piece structure. That is, the flapping wing 2 is made of a whole piece of material. This design can provide better structural strength and stability, while reducing the weight and air resistance of the flapping wing 2. The flapping wing 2 of the one-piece structure can also better simulate the shape and movement of butterfly wings, achieving a more realistic bionic flight effect.

[0077] In some embodiments, two tail frames 32 are arranged symmetrically along the main rod 1 below the tail 3. The function of the two tail frames 32 is to provide additional support and stability so that the tail 3 can better maintain its shape and posture. By symmetrically arranging, it can be ensured that the aircraft has good balance and stability during flight. The design of the tail frame 32 can be adjusted and optimized as needed to meet the performance requirements of the aircraft. Of course, in order to better enhance the strength of the tail 3, more tail frames 32 can be arranged at its edge.

[0078] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
