Description

Technical Field

[0001] The utility model relates to the technical field of bionic flight technology, in particular to a bionic butterfly flight driving device and a flight device. Background Art

[0002] In the field of modern technology, bionics, as an innovative technology, has been increasingly emphasized. By imitating the structures and functions of organisms in nature, it provides new ideas and inspirations for mechanical design. Especially in the design of flight devices, the application of bionic technology has made remarkable progress. However, existing bionic flight devices often have problems such as complex structures, difficult control, and low energy efficiency, which limit their wide promotion in practical applications. For example, although some bionic insect flight devices can simulate the flight actions of insects, they still need to be improved in terms of stability and environmental adaptability.

[0003] As one of the insects with extremely strong flight ability in nature, the flapping mode of the wings of butterflies and their flight control mechanisms have always been the focus of research by scientists. The flapping of butterfly wings can not only generate lift but also enable rapid turning and obstacle avoidance during flight. However, most existing bionic butterfly flight devices use a single motor or servo motor to drive the flapping of the wings, which limits the flexibility of the wing flapping and the stability of flight. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects of the existing technologies described above by providing a bionic butterfly flight driving device and a flight device. By driving a wheel disc to rotate through a motor, and then realizing the flapping of the wings through a secondary rod and a wing connecting piece, it simulates the flight actions of butterflies, is closer to the form of butterflies, can simulate the form of butterflies, and improves the flight flexibility and flight stability.

[0005] The purpose of the utility model can be realized through the following technical solutions:

[0006] The first aspect of the utility model provides a bionic butterfly flight driving device, including a skeleton, a pair of motor carriers, a wheel disc, a secondary rod, and a wing connecting piece. Specifically:

[0007] A pair of motor carriers are symmetrically arranged on both sides of the skeleton, and a servo motor is installed inside the motor carrier.

[0008] The wheel disc has its middle part connected to the output shaft of the servo motor.

[0009] One end of the secondary rod is pivotally connected to the wheel disc.

[0010] The wing connecting member has a wing joint at one end and is pivotally connected to the other end of the auxiliary rod at the other end. The middle of the wing connecting member is pivotally connected to the frame. When the motor carrier is driven by the motor to rotate, the wheel disc is driven to rotate, and the auxiliary rod rotates around a fixed point on the wheel disc, so that one end of the wing connecting member close to the wing joint can perform a reciprocating up-and-down flapping motion.

[0011] Further, the frame has a left-right symmetric structure.

[0012] Further, one end of the auxiliary rod is pivotally connected to the edge of the wheel disc.

[0013] Further, one end of the auxiliary rod is pivotally connected to the edge of the wheel disc by a first shaft pin.

[0014] Further, the other end of the auxiliary rod is pivotally connected to one end of the wing connecting member by a second shaft pin.

[0015] Further, the middle of the wing connecting member is pivotally connected to the frame by a third shaft pin.

[0016] Further, a main rod is provided at the central position of the frame, and the main rod is perpendicular to the plane where the frame is located.

[0017] Further, a battery and a control board are provided inside the main rod, and the battery and the control board are electrically connected to the servo motor respectively.

[0018] Further, a wireless signal transceiver is also provided inside the main rod, and the wireless signal transceiver is wirelessly communicatively connected to an external user terminal.

[0019] Further, the symmetric design, precise shaft pin connection, and built-in battery, control board, and wireless communication function of the device of the present invention enable the device to fly stably and controllably, and have a high degree of bionic characteristics.

[0020] In a second aspect of the present invention, a bionic butterfly flight device is provided, which includes the bionic butterfly flight driving device as described above, and further includes bionic butterfly wings provided on the wing joints.

[0021] Compared with the prior art, the present invention has the following technical advantages:

[0022] 1) The double-motor linkage structure of the present invention not only provides greater torque, but also can more effectively utilize energy and reduce energy loss by precisely controlling the rotation speed and direction of the two motors. This design enables the bionic butterfly flight device to maintain good flight performance under different environmental conditions. Whether in a gentle breeze or a windless environment, it can achieve stable flight, improving the environmental adaptability and energy efficiency of the device.

[0023] 2) A shorter butterfly wing can be adopted, which can reduce the overall weight, make it more portable, increase the flight duration, and use a more ingenious biological structure that is closer to the shape of a butterfly and can mimic the butterfly's form.

[0024] 3) The flapping motion of the wings is controlled by two motors, and the flapping frequency and amplitude of each wing can be adjusted independently, enabling more precise control. It has a faster rotation speed than the servo solutions on the market, can increase the vibration frequency of the butterfly wings, and make the flight more stable. This independent control ability allows the device to quickly respond to minor adjustments during flight, such as rapid turning or obstacle avoidance, providing higher control flexibility and dynamic response capabilities, and being closer to the flight characteristics of real butterflies.

[0025] 4) The device integrates a battery, a control board, and a wireless signal transceiver inside. This not only reduces the weight but also provides a hardware foundation for realizing intelligent control. Through wireless communication with an external user terminal, the device can receive real-time instructions and execute complex flight tasks, such as formation flight and path planning. In addition, the integrated control board can carry advanced algorithms to achieve real-time monitoring and self-adjustment of the flight state, improving the intelligent level of flight.
