The invention discloses a controllably unfolded high-aspect-ratio unmanned aerial vehicle wing rotating and folding mechanism which comprises end covers, a compression spring, lock catches, a rotatingshaft, a key, a torsion spring, wing connecting joints and a pin puller. And the two wing connecting joints are connected with the rotating shaft through bearings. The torsion spring is arranged between the wing connecting joints, and the end of the torsion spring is inserted into holes of the wing connecting joints to form connection. And the group of lock catches and compression springs are arranged above and below the two wing connecting joints. A groove is formed in each lock catch and is connected with the shaft through the key. The end covers are arranged at the two ends of the shaft tosupport the compression springs. The pin puller is fixed to the upper surface of the lower wing connecting joint and connected with the upper wing connecting joint through a plug pin. In the folded state, the wings are rotated to be parallel to a fuselage to complete locking, and the occupied space in the folded state is effectively reduced. During unfolding, controllable unlocking is performed,and rotary unfolding and self-locking can be completed without driving of an additional motor.

    一种可控展开的大展弦比无人机机翼旋转折叠机构,包括端盖、压缩弹簧、锁扣、旋转轴、键、扭转弹簧、机翼连接接头、拔销器。两个机翼连接接头通过轴承与旋转轴进行连接。扭转弹簧布置在机翼连接接头之间,且扭簧的端头插入机翼连接接头的孔内形成连接。两个机翼连接接头的上下分别布置一组锁扣及压缩弹簧。锁扣上布置凹槽,通过键与轴相连。轴的两端布置端盖为压缩弹簧提供支撑。拔销器固定在下机翼连接接头的上表面,通过插销与上机翼连接接头进行连接。在折叠状态下将机翼旋转至与机身平行的状态完成锁死,有效的缩减折叠状态下占用的空间。展开时,进行可控的锁定解除,并且无需额外的电机驱动即可完成旋转展开并自锁。
