The invention discloses an unmanned aerial vehicle folding wingtip mechanism with a lock and capable of being automatically unfolded and remotely unlocked, the unmanned aerial vehicle folding wingtip mechanism comprises a wing and a wingtip, and further comprises an unlocking mechanism, a rotating mechanism and a locking mechanism, a steering engine is used for controlling a lock hook to unlock, rotation is achieved through a hinge and the rotating mechanism of a C-shaped spring, and during folding, due to the clamping force of the C-shaped spring, the wing tip can be automatically unfolded and unlocked through remote control. The wingtip can be stably attached to the lower surface of the wing, the lock hook is gradually lifted by a chamfer at the front end of the lock catch after being unfolded and then hooked into a groove of the lock catch, meanwhile, the torsional spring can firmly lock the lock hook and the lock catch to prevent the wingtip from being folded again, and when the wingtip is unfolded again, the steel wire rope is dragged through the steering engine to achieve the purpose of pulling and unlocking the lock hook. The wing tip can be unfolded without being driven, only one steering engine needed for folding again is used as driving, the mechanism is simple and reliable, unfolding and folding of the wing tip can be rapidly achieved, and the problem that the deployment space and the storage and transportation space of an unmanned aerial vehicle are small can be solved.

    本发明公开了一种带锁且可自动展开遥控开锁的无人机折叠翼尖机构,包括机翼和翼尖,还包括解锁机构、转动机构和锁合机构,本发明通过舵机控制锁钩来解锁,还通过合页以及C型簧的转动机构来实现转动,收折时由于C型簧有夹紧力,使翼尖在机翼下表面能够稳定贴紧,展开后锁钩被锁扣前端倒角逐步抬起后钩进锁扣的槽内,同时扭簧能够使锁钩与锁扣牢牢锁住防止翼尖再次收折,再次打开时通过舵机拽动钢丝绳进而达到拽开锁钩的目的,本发明的结构精巧,展开无须驱动,仅有再次收折所需的一个舵机作为驱动,且机构简单可靠,能够快速实现翼尖的展开和收折,可以解决无人机部署空间及储运空间小的问题。
