The unmanned aerial vehicle damping device comprises a vehicle body, a landing gear and vehicle arms, a box body structure in the landing gear is divided into a first cavity and a second cavity, a box body in the landing gear is filled with magnetorheological fluid, an iron core is fixed to the upper side of the first cavity, a coil is wound around the side face of the iron core, and a pressure adjusting cylinder is arranged in the second cavity; on one hand, the buffer spring is used for buffering, and on the other hand, damping generated by the magneto-rheological body is used for secondary buffering; the adjusting cone is driven to move through the impact force of instantaneous impact on the magneto-rheological body on the supporting legs, so that the magneto-rheological body in the first cavity enters the second cavity, the pressure relief effect is achieved, the pressure of the first cavity and the supporting cylinder is reduced, stable damping is ensured, and the unmanned aerial vehicle can land stably.
本发明涉及一种地理测绘用无人机减震装置,包括机身、起落装置、机臂,起落装置内部箱体结构分为第一空腔和第二空腔,且起落架内部箱体内填充有磁流变液,第一空腔上侧固定有铁芯,铁芯侧面缠绕有线圈,第二空腔设置有压力调节筒;本发明一方面支利用缓冲弹簧进行缓冲,另一方面利用磁流变体产生的阻尼进行二次缓冲;通过支腿受到瞬时冲击对磁流变体的冲击力带动调节锥移动,使第一空腔内的磁流变体进入第二空腔内,实现泄压效果,减小第一空腔和支撑筒的压力,确保减震平稳进行,使无人机平稳降落。
