Abstract

The invention discloses an arm folding device of a multi-axial air vehicle. The arm folding device comprises a first frame, a second frame, a fixing shaft, a rotating shaft, a telescopic module and an arm tube. The arm tube is connected with the first frame and the second frame through the rotating shaft, and the telescopic module is installed between the two frames and fixed through the fixing shaft. When an arm is folded or unfolded, the telescopic module plays a role in clamping round grooves in the arm tube. An arm folding part is connected with a vehicle body and the arm, limiting is achieved through the telescopic module and the grooves in the arm tube, and then folding of the arm is achieved. After the arm folding device is installed on the vehicle body of the air vehicle, no auxiliary tool is needed in the folding process; the arm folding device is simple and reliable in structure and convenient to use and solves the problems that a multi-axial air vehicle is difficult to carry as arms of the multi-axial air vehicle can not be folded, and auxiliary tools are needed when folding is carried out through an existing folding device.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to an arm folding device of a multi-axis aircraft. Background technique [0002] With the wide application of multi-rotor aircraft in civil and military applications, people have put forward requirements for the portability of aircraft. Although folding parts for folding aircraft arms have appeared on the market, such folding parts for aircraft are not easy to operate and require auxiliary tools, which increases the weight of the aircraft and the workload of maintenance personnel to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an arm folding device for a multi-axis aircraft in view of the defects involved in the background technology. [0004] The present invention adopts the following technical solutions for solving the problems of the technologies described above: [0005] An arm folding ...
