The invention relates to an unmanned aerial vehicle wing coaxial folding mechanism, and belongs to the technical field of unmanned aerial vehicle aircrafts. The device comprises a main shaft assembly (1), a right rear wing connecting assembly (2), a left rear wing connecting assembly (3), a thrust bearing (6) and a tension spring (7), it is guaranteed that the rear wings can be fixed in a limited space after being folded, the width of the folded rear wings does not exceed the width of the fuselage, and meanwhile the height of the folded wings can meet the requirement that the wings are placed in a carrying cabin and do not interfere with the carrying cabin. In the flying process of the unmanned aerial vehicle, in order to enable the rear wings to be smoothly unfolded in place and firmly locked under the condition of overcoming self gravity and air resistance, torsional spring drives are arranged in the left rear wing connecting assembly and the right rear wing connecting assembly, a tension spring is connected between the two assemblies, tension drive is increased, and it can be guaranteed that the rear wings can be smoothly unfolded in place in complex air flow.
本发明涉及一种无人机机翼共轴折叠机构,属于无人机飞行器技术领域。为包括:主轴组件(1)、右后翼连接组件(2)、左后翼连接组件(3)、推力轴承(6)、拉簧(7);保证后翼折叠后能在有限空间内固定,后翼折叠后宽度不超过机身的宽度,同时折叠后的机翼高度能满足放置于运载舱内部且与运载舱无干涉。在无人机飞行过程中为了后翼能克服自身重力和空气阻力的情况下顺利展开到位并牢固锁住,在左、右后翼连接组件中设有扭簧驱动,在两个组件之间连接了拉簧,增加了拉力驱动,能确保后翼能在复杂的空气流动中顺利展开到位。
