Description

Technical Field

[0001] This utility model relates to the field of biomimetic device technology, and in particular to a biomimetic wing-vibrating device. Background Technology

[0002] In the field of biomimetic mechanics, a biomimetic wing-vibrating device is a device that achieves flight or specific actions by simulating the wing vibrations of birds or insects. It is commonly used in biomimetic aircraft, biomimetic robots, and other equipment. In traditional technology, the biomimetic wings of a biomimetic wing-vibrating device are generally directly meshed together. A drive mechanism drives one of the biomimetic wings to swing, thereby driving the other biomimetic wing to swing, so as to achieve synchronous swinging of the biomimetic wings. However, using the method of directly meshing the two biomimetic wings not only makes it difficult to control the distance between the two biomimetic wings, but also makes it difficult to control the swinging position of the two biomimetic wings during the assembly process. This leads to deviations in the assembly position of the biomimetic wings, resulting in the technical problem of poor biomimetic effect of the biomimetic wing-vibrating device. Utility Model Content

[0003] Therefore, it is necessary to provide a biomimetic wing-vibrating device to address the technical problem of poor biomimetic effect of the biomimetic wing-vibrating device.

[0004] A biomimetic flapping wing device includes: a housing, a transmission component, a biomimetic wing, and a drive assembly. There are two transmission components and two biomimetic wings. The two transmission components are meshed with each other. The two biomimetic wings are rotatably connected to the housing, and the two biomimetic wings are respectively meshed with each of the transmission components. The drive assembly is installed inside the housing and drives one of the transmission components to rotate, so that the two transmission components drive each biomimetic wing to flap synchronously.

[0005] In one embodiment, the bionic wing includes a tooth and a wing portion, the tooth being rotatably mounted on the housing and engaging with the corresponding transmission component, and the wing portion and the tooth being integrally formed.

[0006] In one embodiment, the drive assembly includes a control unit and a drive unit, the control unit and the drive unit being communicatively connected, the drive unit driving one of the transmission components to rotate.

[0007] In one embodiment, the drive unit includes a transmission wheel set and a drive component, wherein the transmission wheel set meshes with one of the transmission components, and the drive component is driven by a belt or gear through the transmission wheel set.

[0008] In one embodiment, the transmission wheel assembly includes an assembly and a transmission wheel, the assembly being driven by the drive member, the transmission wheel engaging with the assembly, and one of the drive members engaging with the transmission wheel.

[0009] In one embodiment, the housing has a mounting cavity, an isolation cavity, and a receiving cavity connected in sequence. The control unit and the drive component are disposed in the mounting cavity, some of the assembly components are disposed in the isolation cavity, and some of the transmission components are disposed in the receiving cavity.

[0010] In one embodiment, the drive assembly further includes a charging interface and a switch, and the housing is provided with clearance holes corresponding to the positions of the charging interface and the switch.

[0011] In one embodiment, the driving component further includes a sound-generating unit that is communicatively connected to the control unit.

[0012] In one embodiment, the housing includes a first cylindrical body, a second cylindrical body, and a connecting portion. The connecting portion, the first cylindrical body, and the second cylindrical body form an active space. The transmission component includes a transmission portion and a straight tooth portion. The transmission portion is located inside the first cylindrical body of the housing and engages with the drive assembly. The straight tooth portion extends into the active space and engages with the bionic wing.

[0013] In one embodiment, the housing further includes a partition connected to the first and second cylindrical bodies and disposed between the two biomimetic wings.

[0014] The beneficial effects of the bionic wing-beating device provided in this application are as follows: by using two intermeshing transmission components, the drive assembly drives one of the transmission components to rotate, and then drives the corresponding bionic wing to swing through the transmission component, the movement of the two bionic wings is transmitted and controlled through the transmission component. This allows for more precise control of the distance and swing position between the two bionic wings, thereby effectively reducing the positional deviation caused by direct meshing during assembly. This makes the distance and swing of the bionic wings more consistent with the movement patterns of bird or insect wings, achieving the goal of significantly improving the bionic effect of the bionic wing-beating device.

[0032] like Figure 1 As shown, it is the biomimetic wing-shaped device 100 of this utility model.

[0033] like Figures 1 to 3As shown, the biomimetic wing-vibrating device 100 includes: a housing 10, a transmission component 20, a biomimetic wing 30, and a drive assembly 40. There are two transmission components 20 and two biomimetic wings 30. The two transmission components 20 are meshed with each other, and both biomimetic wings 30 are rotatably connected to the housing 10. Each biomimetic wing 30 meshes with a corresponding transmission component 20. The drive assembly 40 is installed inside the housing 10 and drives one of the transmission components 20 to rotate, thereby driving each biomimetic wing 30 to vibrate synchronously through the two transmission components 20. The biomimetic wing-vibrating device 100 employs two... The transmission components 20 mesh with each other, and the drive assembly 40 drives one of the transmission components 20 to rotate. Then, the corresponding bionic wing 30 is driven to swing through the transmission component 20. This allows the movement of the two bionic wings 30 to be transmitted and controlled through the transmission component 20. This enables more precise control of the distance and swing position between the two bionic wings 30, thereby effectively reducing the positional deviation caused by direct meshing during assembly. This makes the distance and swing of the bionic wings 30 more in line with the movement law of bird or insect wings, achieving the goal of significantly improving the bionic effect of the bionic wing-vibrating device 100.

[0034] The following text, combined with Figures 1 to 5 The above-mentioned biomimetic wing-shaped device 100 will be further described.

[0035] like Figures 1 to 2 As shown, the housing 10 includes a first cylindrical body 12, a second cylindrical body 13, and a connecting part 14. The connecting part 14, the first cylindrical body 12, and the second cylindrical body 13 form an active space 101. The transmission component 20 includes a transmission part 21 and a straight tooth part 22 and a tooth part 31. The transmission part 21 is located inside the first cylindrical body 12 of the housing 10 and meshes with the drive assembly 40. The straight tooth part 22 and the tooth part 31 extend into the active space 101 and mesh with the bionic wing 30. The active space 101 formed by the first cylindrical body 12, the second cylindrical body 13, and the connecting part 14 provides sufficient space for the meshing and swinging of the transmission component 20 and the bionic wing 30, ensuring that the transmission component 20 and the bionic wing 30 can swing freely, making the overall layout of the device more compact, and facilitating the maintenance of the meshed part of the bionic wing 30 and the transmission component 20, thereby improving the maintenance convenience of the bionic wing device 100.

[0036] To improve the structural stability of the biomimetic wing-shaped device 100, such as Figure 4As shown, the housing 10 also includes a partition 17, which is connected to the first cylinder 12 and the second cylinder 13 and is disposed between the two bionic wings 30. By placing the partition 17 between the two bionic wings 30, the two bionic wings 30 can be effectively isolated to prevent them from interfering with each other during the swinging process, ensuring that each bionic wing 30 can swing according to the designed trajectory and amplitude. At the same time, the partition 17 enhances the structural strength of the housing 10, enabling the housing 10 to better support and fix the two bionic wings 30, thereby improving the structural stability of the bionic wing device 100.

[0037] To reduce the assembly difficulty and failure rate of the Bionic Wing 30, such as Figure 2 and Figure 5 As shown, the bionic wing 30 includes a toothed part 31 and a wing part 32. The toothed part 31 is rotatably mounted on the housing 10 via a rotating shaft and meshes with the corresponding transmission component 20. The wing part 32 is integrally formed with the toothed part 31. By adopting the integral forming method of the toothed part 31 and the wing part 32, the structural strength and integrity of the bionic wing 30 are enhanced, the connection links between components are reduced, the assembly difficulty and the possibility of failure are reduced. At the same time, the direct meshing of the toothed part 31 with the transmission component 20 can transmit power more efficiently, thereby reducing the assembly difficulty and failure rate of the bionic wing 30 while improving the stability and reliability of the oscillation of the bionic wing 30.

[0038] To improve the wobbling biomimetic effect of the bionic wing 30, such as Figure 2 As shown, the drive assembly 40 includes a control unit 41 and a drive unit 42. The control unit 41 and the drive unit 42 are communicatively connected. The drive unit 42 drives one of the transmission components 20 to rotate. The communication connection between the control unit 41 and the drive unit 42 enables precise control of the drive unit 42. The output parameters of the drive unit 42 can be flexibly adjusted according to different working requirements, thereby precisely controlling the rotation speed and angle of the transmission component 20. This allows for precise adjustment of parameters such as the swing frequency and amplitude of the bionic wing 30, enabling the bionic wing device 100 to adapt to different working scenarios and effectively improving the bionic swing effect of the bionic wing 30.

[0039] like Figure 5As shown, the drive unit 42 includes a transmission wheel set 421 and a drive component 422. The transmission wheel set 421 meshes with one of the transmission components 20. The drive component 422 is a motor and is connected to the transmission wheel set 421 by belt drive or gear drive. The drive component 422 and the transmission wheel set 421 are connected by belt drive. When the transmission wheel set 421 encounters an obstacle or overload, the belt 425 will slip to prevent damage to the drive component 422, thereby extending the service life of the drive component 422. Belt drive has the advantages of smooth transmission, low noise, and shock absorption, which can reduce the impact and vibration during the drive process and improve the overall service life of the drive unit 42. The drive component 422 and the transmission wheel set 421 are connected by gear drive. The rolling friction between the gears can effectively reduce the energy loss of the drive component 422 during the transmission process and effectively ensure the transmission accuracy of the drive component 422 and the transmission wheel set 421, thereby improving the swing accuracy of the bionic wing 30.

[0040] Specifically, such as Figure 3 and Figure 5 As shown, the transmission wheel assembly 421 includes an assembly 423 and a transmission wheel 424. The assembly 423 is belt-driven with the drive component 422, and the transmission wheel 424 meshes with the assembly 423. One of the transmission components 20 meshes with the transmission wheel 424. More specifically, the assembly 423 is a pulley and gear assembly 423, in which the pulley part is belt-driven with the synchronous pulley 426 on the drive component 422 via a belt 425. Through the meshing transmission of the assembly 423 and the transmission wheel 424, the power is transmitted from the drive component 422 to the transmission component 20 in multiple stages. The transmission ratio can be adjusted according to actual needs, thereby precisely controlling the rotation speed of the transmission component 20 and meeting the requirements of the bionic wing 30's swing speed under different working conditions. The multi-stage transmission structure improves the transmission flexibility and adaptability of the drive unit 42, thereby effectively reducing the energy consumption of the drive component 422 and achieving the goal of improving the user experience of the bionic wing device 100.

[0041] To improve the assembly efficiency and maintenance convenience of the biomimetic wing-shaped device 100, such as Figures 2 to 3As shown, the housing 10 has a mounting cavity 102, an isolation cavity 103, and a receiving cavity 104 connected in sequence. The control unit 41 and the drive component 422 are disposed in the mounting cavity 102, some components 423 are disposed in the isolation cavity 103, and some transmission components 20 are disposed in the receiving cavity 104. Specifically, the housing 10 includes an end cap 11, a first cylindrical body 12, a second cylindrical body 13, a connecting part 14, a partition 15, and a tail cap 16. The mounting cavity 102 is formed by the second cylindrical body 13 and the tail cap 16, the isolation cavity 103 is formed by the partition 15 and the connecting part 14, and the receiving cavity 104 is formed by the end cap 11 and the first cylindrical body 12. A partitioned design is adopted (mounting cavity 102, isolation cavity 103, and receiving cavity 104). 03. By using the housing cavity 104, different components are placed in their respective cavities, thus realizing the division of functional areas. The mounting cavity 102 is used to install the control unit 41 and the drive component 422, which facilitates centralized management and maintenance of the control and drive components. The isolation cavity 103 is equipped with some assembly components 423, which can reduce mutual interference between different components and improve the stability of the device. The housing cavity 104 is equipped with some transmission components 20, which provides sufficient space for the rotation of the transmission components 20 and facilitates the meshing and installation of the transmission components 20 and the bionic wing 30. This partitioned structure makes the internal layout of the device more reasonable, thereby improving the assembly efficiency and maintenance convenience of the bionic wing device 100.

[0042] like Figure 1 As shown, the drive assembly 40 also includes a charging interface 43 and a switch 44. The housing 10 is provided with a clearance hole 105 at the positions corresponding to the charging interface 43 and the switch 44. The setting of the charging interface 43 facilitates the charging operation of the device. The energy storage components such as the battery inside the device can be charged without disassembling the housing 10, which improves the convenience of use. The setting of the switch 44 makes it easy for the user to control the working status of the device. The design of the clearance hole 105 ensures that the charging interface 43 and the switch 44 can be properly exposed in the housing 10, thereby improving the user's operational convenience.

[0043] To enhance the application scenarios and appeal of the biomimetic wing-shaped device 100, such as... Figure 2 As shown, the drive assembly 40 also includes a sound-generating unit 45, which is communicatively connected to the control unit 41. The sound-generating unit 45 enables the bionic wing-shaped device 100 to emit corresponding sounds, such as simulating bird calls, further enhancing the bionic function of the device. The communication connection between the control unit 41 and the sound-generating unit 45 can control the sound-generating unit 45 to emit different sounds according to the swinging state of the bionic wing 30 or external control commands, realizing the coordinated bionics of sound and motion, thereby enhancing the application scenarios and fun of the bionic wing-shaped device 100.

[0044] The working principle of the bionic wing-shaped device 100 provided in this application is as follows: When the drive component 40 is working, the drive component 422 drives the assembly 423 to rotate, the assembly 423 drives the transmission wheel 424 to rotate, and the transmission wheel 424 drives one of the transmission components 20 to rotate. Since the two transmission components 20 mesh with each other, they drive the other transmission component 20 to rotate synchronously. The two transmission components 20 respectively drive the teeth 31 of the corresponding bionic wings 30 to rotate, thereby enabling each wing 32 to swing synchronously. The control unit 41 can control the rotation speed, direction and time of the drive component 422 according to the preset program or external input instructions, thereby adjusting the swing frequency, amplitude and direction of the bionic wings 30. At the same time, the control unit 41 can control the sound-emitting unit 45 to emit corresponding sounds, thereby achieving a variety of bionic effects.

[0045] In the assembly process of the bionic wing device 100 provided in this application, since the transmission component 20 and the bionic wing 30 are positioned and installed separately, the assembly position deviation problem caused by the direct meshing of each bionic wing 30 is avoided. Thus, the distance and swing position between the two bionic wings 30 can be controlled more accurately, thereby improving the assembly accuracy and bionic effect of the device.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
