The invention provides a variable-axle-spacing type power arm capable of perpendicularly rising and landing and used for a fixed-wing unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The variable-axle-spacing type power arm comprises a primary arm and a secondary arm, wherein two drive motors which are both connected to a lead screw are symmetrically arranged in the primary arm; the secondary arm is mounted on the lead screw; the secondary arm can perform linear motion on the lead screw according to load changes to realize adjustment of axle spacing of the power arm, thus adjusting the position of the gravity center of the unmanned aerial vehicle, improving stability and safety of unmanned aerial vehicle flight, being simple in structure, and being convenient in operation; and limiting slots are formed in both the primary arm and the secondary arm; bulges which are matched with the limiting slots are arranged on a base mounted on the primary armand the inner wall of a rotor arm on the secondary arm. The variable-axle-spacing type power arm is able to effectively prevent the primary arm and the base as well as the secondary arm and the rotorwing from generating peripheral motion, thus further improving the stability of the whole power arm structure.

    本发明提供了一种垂直起降固定翼无人机的可变轴距式动力臂,属于无人机技术领域;动力臂包括主臂和副臂,主臂内对称设有两个驱动电机,驱动电机均与丝杆连接,丝杆上安装有副臂,根据负载变化,副臂可在丝杆上做线性运动,实现动力臂轴距的调整,从而调整无人机重心位置,提高无人机飞行的稳定性和安全性,结构简单,操作方便;主臂和副臂上均设有限位槽,安装在主臂上的基座以及安装在副臂上的旋翼臂内壁均设有与限位槽相配合的凸起,能够有效防止主臂与基座、副臂与旋翼臂产生周向运动,进一步增强整个动力臂结构的稳定性。
