Embodiment Construction
[0020] Such as figure 1 As shown, the vibrator (3) composed of the eccentric wheel driven by the motor (A) vibrates, which can feed the vibration energy to the wing bar (1), and then drive the wing film (2), so that the whole flapping wing swings;
[0021] Such as figure 2 As shown, when the pump (5) works in a cycle of "suction-squeeze", the working medium fluid will "fill liquid-absorb liquid" to the bionic wing vein pipeline (4) on the flapping wings according to a certain period, and vibrate The mass and rigidity of the wings change periodically, and at the same time, the whole wing flaps due to the joint action of gravity and fluid;
[0022] The electronic control system regulates the flapping drive mechanism and the flapping rigidity and quality adjustment mechanism based on the signals collected by the pressure sensor or acceleration sensor, so that the rigidity or quality of the flapping wings, as well as the vibration frequency and amplitude can reach the best state...
