Description

Technical Field

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

[0002] With the rapid progress of robotics and micro-electromechanical systems (MEMS), bionics, as an important bridge between biological science and engineering technology, has received widespread attention. The current field of bionic robotics mainly focuses on imitating the movement, perception and behavior of organisms, with the goal of developing robotic systems with higher adaptability and flexibility. Among the many bionic objects, butterflies have become a hot topic of research with their unique flying style and elegant shape.

[0003] The research and development of bionic mechanical butterflies helps to deeply explore the mechanism of biological flight and greatly promotes the progress and development of robotics. By simulating the flight mode of butterflies, more flexible and efficient micro-aircraft are developed. These aircraft have shown broad application prospects in the fields of environmental monitoring, geological exploration, military reconnaissance, etc. In addition, the research on bionic mechanical butterflies has also promoted the development of biomimetic science and technology, and provided new ideas and methods for research in the fields of biology and ecology.

[0004] Although there have been a lot of studies on bionic mechanical butterflies at home and abroad, there are still some technical challenges. The first problem is to reduce the weight of the bionic mechanical butterfly. Another key challenge is the landing shock absorption problem, that is, how to reduce the impact of the bionic mechanical butterfly on the body structure when landing to ensure the accuracy of the product and extend its service life. In response to these problems, we propose a bionic mechanical butterfly with a more streamlined overall structure, aiming to achieve efficient, stable flight and safe landing of the bionic mechanical butterfly. Utility Model Content

[0005] In response to the problems existing in the above-mentioned prior art, the utility model provides a bionic mechanical butterfly, which adopts a lightweight design concept and aims to reduce the overall weight of the bionic mechanical butterfly while ensuring that its structural stability is not affected. To this end, the utility model adopts a carbon fiber body and thin wings, thereby effectively saving material resources while maintaining the overall lightness and strength of the bionic mechanical butterfly.

[0006] In order to achieve the above-mentioned purpose, the bionic mechanical butterfly adopted by the utility model comprises the following components:

[0007] A carbon fiber base, wherein the carbon fiber base is provided with a front end mounting portion and a rear end supporting portion in sequence along a straight line direction, and the length of the carbon fiber base is 7-9 cm;

[0008] A controller, the controller being mounted on the tail end support portion;

[0009] A motor is arranged on the front mounting portion and is electrically connected to the controller;

[0010] A programmable adjustable power supply, which supplies power to the motor;

[0011] A frame, the frame is fixedly connected to the front end mounting portion and the frame and the carbon fiber base are arranged vertically;

[0012] A gear set, the gear set comprising a rear gear connected to the motor via a transmission shaft, two front gears rotatably connected to the frame and the two front gears are parallel and meshed in a horizontal direction, one of the front gears is meshed and installed with the rear gear;

[0013] A connecting rod assembly, wherein one end of the first connecting rod is rotatably connected to the tooth surface of the front gear, the other end of the first connecting rod is hinged to the second connecting rod, the angle between the second rod body and the horizontal direction is 40°, one end of the third connecting rod is hinged to the tooth surface of the front gear and the hinged end of the third connecting rod is coaxially hinged to part of the first connecting rod;

[0014] A thin front wing is installed on the second connecting rod and the thin front wing swings with the second connecting rod. The wingspan of the front wing is 30-32cm.

[0015] The above structure improves the bionic mechanical butterfly in two aspects. One is lightness. In this aspect, the utility model adopts a streamlined gear set-connecting rod drive structure. At the same time, it adopts a carbon fiber body and thin wings. While maintaining the lightness and strength of the bionic mechanical butterfly, it achieves efficient utilization of material resources and controls the overall weight below 15 grams.

[0016] On the other hand, in order to ensure stability, the utility model draws on the morphological characteristics of the Alexander butterfly, sets the length of the carbon fiber base to 7 to 9 cm (preferably 8 cm), and designs the wingspan of the front wing to 30 to 32 cm (preferably 31 cm), forming a highly simulated Alexander butterfly morphology and significantly enhancing its flight stability.

[0017] Furthermore, after multiple tests, comparisons and analyses, the installation positions of the gear set and the motor were determined to make the center of gravity of the bionic mechanical butterfly more stable. Specifically, the gear set and the motor were installed 2 cm from the front end of the bionic mechanical butterfly.

[0018] In addition, the bionic mechanical butterfly of this design is designed with an upward dihedral angle when stationary, and its lateral stability is enhanced when moving to the left or right. Its working principle is based on the principle of aerodynamics. When the butterfly moves to one side, the relative airflow will form a component acting on the inner side of the wing on that side. At the same time, due to the upward tilt of the butterfly, part of the airflow will hit the lower side of the wing, generating a restoring torque to help the butterfly maintain stability. When the wings flap, the upper angle is greater than the lower angle, forming an airflow pressure difference, generating an upward lift force, and achieving sustainable flight. In order to control the up and down flapping of the wings and maintain their good deformation ability, the main rod of the wing is designed at a 40-degree angle to the central axis. At the same time, through the multi-link structure, the solidity of the connecting rod is enhanced, and the inertia of the bionic mechanical butterfly is improved, so that it can better maintain the balance of forward flight.

[0019] As a further optimization of the above scheme, a rotating shaft is also provided on the frame, and a rotating block is connected to the rotating shaft. The second connecting rod passes through the rotating block and can drive the rotating block to rotate around the rotating shaft, thereby limiting the rotation range of the second connecting rod by the rotating block to avoid position displacement of the second connecting rod during the swinging process.

[0020] As a possible optimization scheme for the above scheme, a buffer plate is provided under the carbon fiber base, and the buffer plate is connected to the carbon fiber base by a telescopic rod, and the telescopic rod includes a fixed cylinder fixed on the buffer plate and a sliding cylinder installed in the fixed cylinder and slidably connected to the fixed cylinder, a spring column is fixed to the inner side of the fixed cylinder, and a moving block is fixed to the side of the spring column away from the fixed cylinder, and a first inclined rod and a second inclined rod arranged oppositely are hinged on the moving block, a first magnetic block is installed on the lower surface of the buffer plate, and a second magnetic block is installed on the upper surface of the carbon fiber base, the first magnetic block and the second magnetic block are magnetically repelling, one end of the first oblique rod is hinged on the first magnetic block, and one end of the second oblique rod is hinged on the second magnetic block.

[0021] The structure combines the shock-absorbing design of telescopic rods, springs and magnetic repulsion mechanisms. While providing strong shock-absorbing capabilities, it also enhances the stability and durability of the structure. At the same time, the structure is relatively simple and has little impact on the weight of the bionic mechanical butterfly, ensuring that the bionic mechanical butterfly can achieve the shock-absorbing function without much change in weight.

[0022] The bionic mechanical butterfly of the utility model has the following beneficial effects:

[0023] 1. The bionic mechanical butterfly of the present invention improves the bionic mechanical butterfly in two aspects. On the one hand, it is light. In this aspect, the present invention simplifies the driving structure into a simple gear set-connecting rod structure, simplifies the driving components, and adopts a carbon fiber fuselage and thin wings, so as to effectively save material resources while maintaining the overall lightness and strength of the bionic mechanical butterfly. The actual overall weight after installation is less than 15g; on the other hand, it is stable. In the present invention, the existing Alexander butterfly form is simulated, the length of the carbon fiber base is set to 7-9cm, preferably 8cm, and the wingspan of the front wing is designed to be 30-32cm, preferably 31cm, to form an Alexander butterfly-like form with strong stability.

[0024] 2. In terms of shock absorption, the bionic mechanical butterfly of the utility model combines the shock absorption design of telescopic rods, springs and magnetic repulsion mechanisms. While providing powerful shock absorption capabilities, it also enhances the stability and durability of the structure. At the same time, the structure is relatively simple and has little effect on the weight of the bionic mechanical butterfly, ensuring that the bionic mechanical butterfly can achieve the shock absorption function without much change in weight.

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the scope of the utility model.

When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] Please refer to the instruction manual Figure 1-5 The utility model provides a first embodiment of a bionic mechanical butterfly, and the bionic mechanical butterfly in this embodiment includes the following components:

[0037] Carbon fiber base 1: The carbon fiber base 1 is divided into a front mounting portion 11 and a rear supporting portion 12 along a straight line direction, and the length is set to 7 to 9 cm (preferably 8 cm) to ensure the stability and lightness of the structure;

[0038] Controller 2: The controller 2 is installed on the tail end support part 12 and is responsible for the control of the overall movement;

[0039] Motor 3 and programmable adjustable power supply: Motor 3 is arranged at the front mounting portion 11 and is electrically connected to the controller 2, and is powered by a programmable adjustable power supply to ensure stable and adjustable power;

[0040] It should be noted that in order to make the bionic mechanical butterfly of the utility model fly more stably, based on the principle of flight, the programmable adjustable power supply adjusts the output voltage to achieve sinusoidal variable speed flapping, so that the airflow above and below the wings forms a pressure difference, the airflow under the wings is greater than the airflow above the wings, forming a lifting force greater than the self-weight of the bionic butterfly, allowing it to fly sustainably and realize the adjustable frequency of the left and right wings for steering.

[0041] Frame: The frame is fixedly connected to the front-end mounting portion 11 and is arranged vertically with the carbon fiber base 1 to support and connect the gear set 4.

[0042] The gear set 4 is composed of a rear gear 41 connected to the motor 3 and two parallel and meshing front gears 42 rotating on the frame, wherein one of the front gears 42 meshes with the rear gear 41 to form a simplified driving structure.

[0043] Linkage group 5: includes a first link 51, a second link 52 and a third link 53. One end of the first link 51 is connected to the tooth surface of the front gear 42, and the other end is hinged to the second link 52. The third link 53 is hinged to the tooth surface of the same front gear 42 and is partially coaxially hinged with the first link 51. In particular, the second link 52 is at an angle of 40° to the horizontal direction, which optimizes the power transmission and the effect of wing flapping.

[0044] The thin front wing 6 is installed on the second connecting rod 52, with a wingspan of 30 to 32 cm (preferably 31 cm), and swings with the swing of the second connecting rod 52 to achieve bionic flight.

[0045] The improvements of the above structure are mainly reflected in two aspects: lightness and stability:

[0046] Light: The carbon fiber body and thin wings, combined with a streamlined gear set 4-link drive structure, effectively reduce the overall weight of the bionic mechanical butterfly, while maintaining the strength and stability of the structure, so that the overall weight is controlled below 15 grams, achieving efficient use of material resources.

[0047] Stable, drawing on the morphological characteristics of the Alexander butterfly, by accurately designing the size of the carbon fiber base 1 and the front wing, a highly simulated Alexander butterfly morphology is formed, which significantly enhances the flight stability. In addition, after multiple tests and analyses, the gear set 4 and the motor 3 are installed 2 cm from the front end of the bionic mechanical butterfly, which further optimizes the center of gravity distribution and enhances the flight stability.

[0048] It should be noted that the bionic mechanical butterfly of this design adopts an upward dihedral design when stationary, so that the lateral stability is enhanced when moving left or right. Its working principle is based on the principle of aerodynamics, and sustainable flight is achieved through the flapping of the wings and the special angle design. In addition, the main rod of the wing is at an angle of 40 degrees to the central axis, which effectively controls the up and down flapping of the wings while maintaining good deformation ability.

[0049] Furthermore, the frame is also provided with a rotating shaft 7, and the rotating shaft 7 is connected to a rotating block 8. The second connecting rod 52 passes through the rotating block 8 and can drive the rotating block 8 to rotate around the rotating shaft 7, thereby limiting the rotation range of the second connecting rod 52 through the rotating block 8 to avoid position displacement of the second connecting rod 52 during the swinging process.

[0050] As a further possible solution to the above solution, please refer to Figure 6 From the perspective of preventing parts from being damaged, the utility model proposes to add a shock-absorbing structure. Specifically, a buffer plate 9 is provided below the carbon fiber base 1, and the buffer plate 9 is connected to the carbon fiber base 1 through a telescopic rod 91. The telescopic rod 91 includes a fixed cylinder 911 fixed on the buffer plate 9 and a sliding cylinder 912 installed in the fixed cylinder 911 and slidably connected to the fixed cylinder 911. A spring column 92 is fixed to the inner side of the fixed cylinder 911, and a moving block 93 is fixed on the side of the spring column 92 away from the fixed cylinder 911. A first oblique rod 94 and a second oblique rod 95 arranged oppositely are hinged on the moving block 93. A first magnetic block 96 is installed on the lower surface of the buffer plate 9, and a second magnetic block 97 is installed on the upper surface of the carbon fiber base 1. The first magnetic block 96 and the second magnetic block 97 are magnetically repelling. One end of the first oblique rod 94 is hinged on the first magnetic block 96, and one end of the second oblique rod 95 is hinged on the second magnetic block 97.

[0051] The above-mentioned shock-absorbing structure combines the shock-absorbing design of the telescopic rod 91, the spring and the magnetic repulsion mechanism, which not only provides a strong shock-absorbing ability, but also enhances the stability and durability of the structure. At the same time, the structure is relatively simple and has little effect on the weight of the bionic mechanical butterfly, ensuring that the bionic mechanical butterfly can achieve the shock-absorbing function without much change in weight.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
