Abstract

The invention provides a rotation locking mechanism and a plant protection UAV having the same, wherein the rotation locking mechanism includes a locking lifting lug provided on the main body of the frame and a rotation connecting piece provided on the pivot end of the swing arm; the lock The outer edge of the locking lug includes an arc segment and a straight segment. The rotating connector is provided with a flange that is in close contact with the outer edge of the locking lug. The flange cooperates with the straight segment of the outer edge to limit the swing arm. Rotate in the unfolding direction; the rotating connector is provided with a lock hook, and an elastic member is provided between the lock hook and the rotating connector for exerting stress that drives the hook portion of the lock hook toward the swing arm; the locking lug is provided with The locking part matched with the locking hook is used to restrict the rotation of the swing arm around the pivot end when the locking hook and the locking part are matched, so as to solve the technical problems of complicated assembly process and limited application range of existing plant protection drones.

Description

technical field [0001] The invention relates to the field of plant protection drones, and more specifically, to a rotation locking mechanism and a plant protection drone with the same. Background technique [0002] At present, there are few practical folding mechanisms in single-rotor plant protection drones. In multi-rotor plant protection drones, there are basically two folding methods, one is the arm and frame plug-in design, and the other is It is designed to be similar to the DJI S1000, with the arms folded down. [0003] Among them, the design of the plug-in and folding method is cumbersome during operation and assembly, and the risk avoidance of the assembly is poor. Mistakes are prone to occur during the assembly process, resulting in damage to the rotor and rotating connection parts of the plant protection drone; the plant protection drone designed with the downward folding method Man-machines are only suitable for drones with small loads, which greatly limits the ...
