The invention relates to an unmanned aerial vehicle wing folding and unfolding structure. A stepping motor is connected with the input end of a commutator through a planetary reducer and a gear reducer; two output ends of the reverser are respectively connected with the left wing shaft end and the right wing shaft end, and the shaft shoulder sleeve is arranged between the left wing shaft end and the right wing shaft end; the left wing shaft end is fixedly connected with the lower-layer reinforcing shaft sleeve, and the right wing shaft end is fixedly connected with the upper-layer reinforcing shaft sleeve; and the upper-layer reinforcing shaft sleeve and the lower-layer reinforcing shaft sleeve independently rotate in opposite rotating directions. According to the folding wing unmanned aerial vehicle, the four front and rear wings can be folded in the direction of the unmanned aerial vehicle body in a layered mode, the space utilization rate of the unmanned aerial vehicle in the parking, transporting and launching states is greatly increased, and the folding wing unmanned aerial vehicle can stably, efficiently and synchronously unfold and fold the wings; the stability of the folding wings during high-speed flight can be ensured, and the folding wings have good aerodynamic characteristics.

    本发明涉及一种无人机机翼折叠展开结构,步进电机通过行星减速器、齿轮减速器连接换向器的输入端;换向器的两个输出端分别连接左侧机翼轴端和右侧机翼轴端,轴肩套设置于左侧机翼轴端和右侧机翼轴端之间;左侧机翼轴端与下层加强轴套固定连接,右侧机翼轴端与上层加强轴套固定连接;上层加强轴套与下层加强轴套为转动方向相反的独立转动。本发明,能够使前后4片机翼分层折叠到无人机机身方向上,大大提高无人机停放、运输、发射状态空间利用率,实现折叠翼无人机能够平稳、高效、同步地进行机翼展开与收拢动作,能够保证高速飞行时折叠机翼的稳定性以及具有良好的气动特性。
