The invention belongs to the field of unmanned gyroplanes, and particularly relates to an arm folding or unfolding mechanism for an unmanned gyroplane. The folding/unfolding mechanism aims to solve the problems that most folding/unfolding mechanisms at present are complex in structure, the mass is large, and the endurance time of an unmanned aerial vehicle is shortened. According to the unmanned aerial vehicle, a support is detachably and fixedly connected with an unmanned aerial vehicle body, the support is rotationally connected with a vehicle arm, a limiting clamping groove is formed in the vehicle arm, a limiting plate is arranged in the limiting clamping groove, the limiting plate is arranged in a movement groove and moves along the movement groove, the movement groove is formed in the support, and the limiting plate is used for achieving stable limiting of the folded and unfolded states of the vehicle arm; and the limiting plate is driven by the driving mechanism to do reciprocating rectilinear motion. The folding/unfolding mechanism is simple in structure and easy to operate, and meanwhile, compared with a traditional folding/unfolding mechanism, the limiting plates and the limiting grooves of the folding/unfolding mechanism are matched properly, so that the folding/unfolding mechanism has very high stability.
本发明属于旋翼无人机领域,具体涉及了一种旋翼无人机用机臂折叠或展开机构。旨在解决目前大多数折叠/展开机构结构复杂,导致质量较大,缩减了无人机的续航时间的问题。本发明包括:支座与无人机主体可拆卸固定连接,支座与机臂转动连接,机臂上开设有限位卡槽,限位卡槽内设置有限位板,限位板设置在运动槽内并沿其移动,运动槽开设在支座上,限位板用于实现机臂折叠、展开状态的稳定限位,限位板在驱动机构的驱动下往复直线运动。本发明结构简单,操作简单,同时该结构与传统折叠/展开机构相比,本发明在设计的限位板与限位槽的配合较为恰当,因而使用本发明具有很高的稳定性。
