The invention discloses a logistics unmanned aerial vehicle landing position correcting system. A first assembly comprises position correcting plates arranged oppositely and a driving mechanism for driving the position correcting plates to move. The position correcting plate is provided with a position correcting surface. A second assembly comprises a bottom support, a ball and a retainer; a through hole is formed in the retainer, and the diameter of the through hole is smaller than that of the ball; the retainer and the bottom support are buckled to buckle the ball in the space, and the top of the ball protrudes out of the through hole; the ball rolls in the through hole; the bottom support is fixed to an unmanned aerial vehicle chassis, so that the ball wrap the chassis circumferentially. The position correcting surface makes contact with the ball, and generates sliding friction in the circumferential direction of the chassis, and the unmanned aerial vehicle in the unmanned aerial vehicle landing position is pushed to reach the designated position. According to the invention, through translational motion with one degree of freedom in one direction, the position correction of thedegree of freedom in two directions of the unmanned aerial vehicle is realized. A position correcting device is simple in structure, easy to control and small in occupied space, synchronization of position correcting movement of the unmanned aerial vehicle in the two directions is effectively achieved, and the problem of complex control is overcome. Abrasion of the unmanned aerial vehicle chassisis reduced.
本发明公开了一种物流无人机降落正位系统,第一组件包括相对设置的正位板,以及驱动正位板移动的驱动机构;正位板上设置正位面。第二组件包括底托、滚珠、保持架;保持架上设置通孔,通孔直径小于滚珠直径;保持架和底托扣合将滚珠扣在空间,滚珠顶部从通孔冒出;滚珠在通孔内滚动;底托固定在无人机底架上,使滚珠沿底架周向包裹底架。正位面与滚珠接触、沿底架周向产生滑动摩擦,推动无人机降落位内的无人机到达指定位置。本发明通过一个方向自由度的平动运动,实现无人机两个方向自由度的正位。该正位装置结构简单,控制简单,占用空间小,有效实现了无人机两个方向正位运动的同步、控制复杂的问题。减少无人机底架的磨损。
