The invention relates to the technical field of foldable unmanned aerial vehicles, and provides a cylinder-launched unmanned aerial vehicle unfolding mechanism with spring-driven connecting rods and an unmanned aerial vehicle. The cylinder-launched unmanned aerial vehicle unfolding mechanism comprises a base, a spring-driven assembly and two connecting rod assemblies which are the same in structure and are arranged in a spatial staggered mode; a limiting long hole is formed in the base; each connecting rod assembly comprises a first connecting rod and a special-shaped connecting rod, and one end of the first connecting rod is rotationally connected with one end of the special-shaped connecting rod. The other ends of the two first connecting rods are connected through a first connecting column, and the first connecting column is slidably arranged in a limiting long hole in the base. The second ends of the two special-shaped connecting rods are jointly hinged to the base. The third ends of the two special-shaped connecting rods are respectively connected with the two wings; the first connecting columns of the two first connecting rods are connected to the spring driving assembly so that the first connecting columns can move in the limiting long holes to complete the unfolding action of the wings. One-time unfolding of the wings is achieved, complex limiting and locking structures are omitted, and the response speed and stability of the unfolding mechanism are improved.
本发明涉及可折叠无人机技术领域,提出了一种弹簧驱动连杆的筒射无人机展开机构及无人机,包括底座、弹簧驱动组件以及两组结构相同且空间错位布置的连杆组件;底座上设置限位长孔;每组连杆组件包括第一连杆与异型连杆,第一连杆的一端与异型连杆的一端可转动连接;两个第一连杆的另一端通过第一连接柱相连接,第一连接柱可滑动设置在底座上的限位长孔中;两个异型连杆的第二端共同铰接于底座上;两个异型连杆的第三端分别连接两个机翼;两个第一连杆的第一连接柱连接至弹簧驱动组件,以使得第一连接柱在限位长孔中移动以完成机翼的展开动作。实现了机翼的一次性展开,省去复杂的限位和锁定结构,提升了展开机构的响应速度与稳定性。
