Method for portable folding novel multi-rotor unmanned aerial vehicle

Abstract

The invention provides a method for portable folding a novel multi-rotor unmanned aerial vehicle. Firstly, foldable propellers are folded to the direction of a vehicle body, the folded foldable propellers are aligned with corresponding foldable vehicle arms; the foldable vehicle arms are coaxially hinged to vehicle arm bases, at the moment, the vehicle arms are rotated and folded so as to be perpendicular to the vehicle arm bases, and the foldable vehicle arms form an alpha angle with the vertical direction; and the foldable vehicle arms continuously rotate for a beta angle to the direction of the vehicle body, and the portable folding of the vehicle arms is completed. According to the method for portable folding the novel multi-rotor unmanned aerial vehicle, the dimensions of the length and the width of the multiple rotors after being folded can be greatly compressed by adopting a method that folding of the vehicle arms in a tilt space is matched with folding of the propellers, meanwhile, relative to vertical folding of the vehicle arms, the requirements for the height of an undercarriage can be lowered greatly, the dimension of the overall vehicle after being folded is reduced to a largest extent, and the portability of product transporting is improved effectively.

Description

technical field [0001] The invention belongs to the field of aviation aircraft, and in particular relates to a portable folding method for a novel multi-rotor unmanned aerial vehicle. Background technique [0002] Multi-rotor UAVs have developed rapidly due to their characteristics of easy operation, vertical take-off and landing, no need for site requirements, and high cost performance. , plant protection, security, surveying and mapping and other fields. With the continuous excavation of the needs of various industries, in order to meet the needs of long endurance, the size of the multi-rotor UAV is constantly increasing, which leads to the continuous increase of the collection size, which affects the transportation and use of UAVs. In order to meet the portability requirements for multi-rotor UAVs, UAV portable technologies such as quick-release propellers, folding arms, and pluggable arms have emerged as the times require. In the prior art, there are generally two form...

AI Technical Summary

Problems solved by technology

In the prior art, there are generally two forms of folding arms of UAVs: horizontal folding and vertical folding; both folding methods have a large remaining space after the multi-rotor is stored, and the horizontal folding is affected by the The interference of adjacent machine arms, the length and width of the whole machine are large after storage, and the lower space is wasted after folding; the folding length of the vertical folding arm needs to be guaranteed by the height of the landing gear, and the horizontal length and width are reduced In the case that the height of the fuselage increases, there is still a large waste of space; another pluggable arm can quickly disassemble the fuselage, but with the increase of the arms, the operation time will increase, which is not conducive to portability Transportation and fast operation; therefore, the market urgently needs a new portable folding method for multi-rotor UAVs, which can effectively use space, reduce the volume of UAVs after folding, and improve the portability of UAVs
