Abstract

The invention relates to an unmanned aerial vehicle arm locking and unlocking device and an unmanned aerial vehicle. The unmanned aerial vehicle arm locking and unlocking device comprises a framework, a vehicle arm, a vehicle arm locking mechanism and a vehicle arm unlocking drive mechanism. The vehicle arm can rotate back and forth relative to the framework between the vehicle arm containing position and the vehicle arm unfolding position. The vehicle arm unlocking drive mechanism comprises a shifting buckle and a rotary disc. The surface, facing the vehicle arm locking mechanism, of the rotary disc is provided with a flange capable of making contact with the shifting buckle. Return elastic force is exerted on the vehicle arm locking mechanism in the radial direction of the rotary disc and drives the vehicle arm locking mechanism to move towards the vehicle arm locking position to lock the vehicle arm on the vehicle arm unfolding position. On the vehicle arm unfolding position, when the rotary disc rotates, the shifting buckle is shifted through the flange to displace inwards in the radial direction of the rotary disc to drive the vehicle arm locking mechanism to retract inwards in the radial direction of the rotary disc to unlock the vehicle arm. According to the unmanned aerial vehicle arm locking and unlocking device, reliability of vehicle arm folding and unfolding is improved; and in addition, the structure is simple, and cost is low.

Description
