Abstract

The invention belongs to the technical field of unmanned aerial vehicles and discloses an arm folding system of a multi-rotor unmanned aerial vehicle. The arm folding system of the multi-rotor unmanned aerial vehicle is provided with arms; the arms are positioned in holes of tube sleeves; one end of a guide column is fixed on a stopping slide block, and the other end of the guide column is arranged in a limiting block; a spring is positioned on the guide column; and the stopping slide block is placed in a slide groove of a side stop block. The arms of the arm folding system can be automatically unfolded, thereby solving the problem of too large wingspan of the unmanned aerial vehicle, reducing the transport volume and being convenient for transporting; and after the arms are unfolded, thearms are automatically locked, the structure of the folded part is stable, and the arms can not shake when being subjected to upward or downward force.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an arm folding system of a multi-rotor unmanned aerial vehicle. Background technique [0002] A multi-rotor UAV is an unmanned aircraft with multiple arms, which are powered by motors on the arms to generate physiology; the arms are in a radial position relative to the fuselage, and the arms make the space occupied by the UAV at least increase more than doubled. After the drone arm is unfolded, it takes up a lot of space, which increases the transportation cost, and is prone to bumps, which affects the life of the drone. At present, there are few multi-rotor UAVs using folding arms, and the design of the folding mechanism must ensure the stability and operability of the structure, and the reliability of the folding mechanism is an important prerequisite for ensuring the stable flight of UAVs. The technical difficulty lies. [0003] To sum up, the p...
