[0015] Beneficial effects: Compared with the prior art, the bionic butterfly flapping wing system of the utility model has the following advantages:

[0016] The overall support of the aircraft of the utility model is stable: the two steering gear sleeves are integrally connected together at an angle of 40 degrees to form a steering gear frame, which can better reduce the resistance encountered by the aircraft during flight.

[0017] The utility model has fast signal transmission: the flight control board is a flapping-wing aircraft control board based on the ATmega328p microcontroller, which can be applied to the control systems of servo-driven flapping-wing aircraft and bionic butterflies. The flight control board integrates the servo interface, receiver interface, and battery interface and weighs only 2g, which not only enables it to receive, process and transmit information faster, improve the overall receiving performance of the aircraft, but also further reduce the weight, providing favorable conditions for the lighter quality requirements of the aircraft.

This mechanism can provide sufficient power for the swing of the left and right wings while ensuring a relatively light weight, thereby controlling the aircraft to complete various actions.

[0019] The utility model has a unique wing structure: the left and right wing components are designed with flexible front wings and hind wings. During the flapping process, due to the different deformation amounts of the front and rear wings under the action of air resistance, the edge of the front wing generates an oblique upward lift, thereby making the butterfly fly forward.

[0023] The bionic butterfly flapping wing system of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Example

[0025] The utility model discloses a high-performance aircraft based on butterfly bionic technology that can be applied to simple life scenes. The utility model takes the Papilio chrysotoptera as a bionics prototype, analyzes its biological structure and observes its movement laws, summarizes and designs a bionic flight structure, and proportionally enlarges the principle structure to obtain a bionic butterfly model similar to the actual butterfly physiological structure, and further completes the specific flight mechanical structure design based on this.

[0026] like Figure 1-2As shown, a butterfly flapping flying machine of the utility model includes a main frame, a power system, a control system and a power supply system. The main frame includes a main rod 3, a board cabin 6 and a steering gear frame 10. The power system includes a right wing 1, a left wing 7, two left and right steering gear arms 8 and two left and right steering gears 9. The control system includes a receiver 4 and a PCB board 5. The power supply system includes a lithium battery 2.

[0027] In the main frame, the front end of the main rod 3 is installed and fixed with the steering gear frame 10, the board cabin 6, the PCB board 5 and the receiver 4 in sequence from front to back, and the rear end of the main rod 3 is fixed with the lithium battery 2.

[0028] In the power system, the left wing 7 and the right wing 1 are fixedly connected to their respective steering gear arms 8, and are connected to the steering gear 9 through the steering gear arms 8 in a gear meshing manner. The left and right steering gears 9 are respectively inserted into the slots of the steering gear frame 10 at an angle of 40°. The steering gear frame 10 is provided with a hole in the middle and the main rod 3 is inserted.

[0029] The left wing 7 and the right wing 1 are symmetrical in structure and have the same size parameters. Both wings include forewings, hindwings and wing membranes. The frame structure of the forewings and hindwings is composed of carbon rods with diameters of 0.8mm and 1mm. The wing skeleton is paved with wing membranes, and the forewings of the wings are the main driving parts of the aircraft. The wing main rods located at the forewings of the wings on the right wing 1 and the left wing 7 extend inwards by 3 cm and are bonded to the steering gear arm 8. The steering gear 9 drives the wing main rod to swing and then drives the forewing to flap and the hindwing to follow. Thus, the flapping of the left and right wings of the bionic butterfly aircraft is realized by the steering gear control to generate lift and thrust. A fixing rod is also provided, which is arranged behind the steering gear frame 10 connected to the main rod 3 to fix the hindwing. The board cabin 6 cooperates with the main rod 3 through the holes designed on the top and is arranged behind the fixing rod.

[0030] The control system is installed in the middle of the main frame and is used to send control instructions to the steering gear 9 in the power system. The PCB board 5 and the receiver 4 are placed in the board compartment 6 to protect the PCB board 5 and the receiver 4.

[0031] The power supply system is installed at the tail of the main frame to power the bionic butterfly aircraft. The lithium battery 2 is 7.4V. A protruding hole is provided on one side of the shell of the lithium battery 2 to facilitate the insertion of the main rod 3. The interface of the servo 9, the interface of the receiver 4 and the interface of the lithium battery 2 are connected to the designated pins on the PCB board 5 to realize the passage, and the receiver 4 and the remote controller realize the sending and receiving of signals through wireless Bluetooth.

[0032] In the utility model, the working principle is as follows: when the power switch of the remote control is turned on, the amplitude control joystick of the servo 9 is adjusted to the highest position, and then the signal is connected with the receiver 4 on the aircraft. When the light on the receiver 4 flashes continuously, it indicates that the signal connection is successful, and then the left joystick of the model aircraft remote control is pushed. After the receiver 4 receives the signal, it immediately transmits information to the PCB board 5. Then the PCB board 5 sends a command to the servo, and the servo drives the servo arm to move, thereby driving the left and right wings to vibrate up and down. During the flight of the machine, when the right joystick is pushed, the wings on both sides of the machine realize a series of difficult actions such as left and right steering and climbing and descending through the phase difference and the change of vibration amplitude.

[0033] The utility model discloses a novel bionic butterfly aircraft driven by dual servos, which independently controls the up and down swing amplitude, flapping frequency and initial and final phases of the wings on both sides through a control system, so that the machine can fly efficiently and stably, complete a series of actions such as ascent, descent and turning, and realize autonomous flight of the bionic butterfly aircraft.

[0034] The above content clearly and completely describes the technical solutions in the embodiments of the utility model, so that those skilled in the art can better understand the advantages and features of the utility model, thereby making a clearer definition of the protection scope of the utility model. The embodiments described in the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the utility model.
