Fixing device for unmanned aerial vehicle arms and unmanned aerial vehicle

Abstract

The fixing device for the unmanned aerial vehicle arm comprises a limiting support, a limiting piece, an elastic piece and a connecting piece, the elastic piece is arranged in the limiting support and arranged on the limiting piece in a sleeving mode, the limiting support is arranged on the connecting piece, and the limiting support comprises a limiting cover plate and a guide groove; the limiting piece penetrates through the guide groove and can slide in the guide groove, a limiting hole is formed in the limiting cover plate, the limiting piece can be clamped with the limiting hole through rotation, the first end of the connecting piece is connected with a fuselage assembly of the unmanned aerial vehicle, the second end of the connecting piece is connected with an arm assembly of the unmanned aerial vehicle, and the arm assembly is provided with a limiting groove. The limiting piece can be clamped to the limiting groove in a sliding mode. The vehicle arm can be prevented from being loosened from the vehicle body due to long-time vibration, and meanwhile, the disassembly and assembly convenience is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a fixing device for an unmanned aerial vehicle arm and an unmanned aerial vehicle. Background technique [0002] For larger drones, a detachable arm design is often used to reduce the packing size of the drone. The detachable arm solution adopted in the prior art usually realizes the fixation of the arm only by the tightening force of the thread or the buckle. The method of buckling and fixing the arm cannot well cope with the long-term vibration caused by the drone when it works for a long time. The arm of the drone is often loosened or disconnected from the fuselage due to long-term vibration. In other solutions in the prior art, the locking pin is used to prevent the nut from loosening, so as to realize the fixation of the machine arm and the fuselage. In this solution, when disassembling the machine arm, one hand is required to operate the locking pin to pre...

AI Technical Summary

Problems solved by technology

The detachable arm scheme adopted in the prior art usually only realizes the fixation of the arm by thread tightening force or buckle. The way of buckling and fixing the arm cannot well deal with the long-term vibration scene when the UAV works for a long time. The arm of the UAV often loosens or disengages from the fuselage due to long-term vibration.

Other solutions in the prior art prevent the nut from loosening through the anti-loosening buckle and the locking pin, so as to realize the fixation of the machine arm and the fuselage. When disassembling and assembling the machine arm, one hand is required to operate the locking pin to prevent it from returning. The other hand rotates the nut. When this solution is applied to a UAV with a large carbon tube diameter, it needs to be rotated with one hand, so there is a defect in the convenience of operation.
