Problems solved by technology

[0003] The arms of the multi-rotor unmanned aerial vehicles have fixed and folding types. The fixed arms occupy a large space, resulting in a large geometric size of the drone, which is not convenient for the transportation and storage of multi-rotor unmanned aerial vehicles; The arm can reduce the overall size of the drone. However, the folding structure of the existing folding arm is relatively complicated, and the operation is relatively cumbersome, which affects the work efficiency to a certain extent.

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to a folding vehicle arm and a multi-rotor unmanned aerial vehicle. The vehicle arm comprises a main vehicle armbody, a first folding vehicle arm body, a second folding vehicle arm body and a folding component. The folding component comprises a shell, a button shaft, a gear disc and a compression spring, wherein the button shaft, the gear disc and the compression spring are sequentially arranged in the shell from top to bottom, the compression spring is arranged between the gear disc and the shell, the topof the button shaft extends upwards to the outer side of the shell, and the bottom of the button shaft is fixedly connected with the gear disc; and one end of the main vehicle arm body is fixedly connected to the inside of the shell, and one end of the first folding vehicle arm body and one end of the second folding vehicle arm body are rotationally connected to the inside of the shell and engaged with the gear disc through first transmission teeth arranged at the end of the first folding vehicle arm body and second transmission teeth arranged at the end of the second folding vehicle arm body. The provided folding vehicle arm is convenient to fold, work efficiency can be effectively improved in actual operation, the overall size of the multi-rotor unmanned aerial vehicle is reduced, and transportation and storage of the multi-rotor unmanned aerial vehicle are convenient.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a folding machine arm and multi-rotor unmanned aircraft. Background technique [0002] Multi-rotor unmanned aerial vehicle is also called multi-axis aircraft. It is controlled by three or more independent power systems. It has a simple structure and can be controlled by coordinating the speed between the motors. The attitude of the aircraft is high. It has a very broad field of use and research value. [0003] The arms of the multi-rotor unmanned aerial vehicles have fixed and foldable types. The fixed arms occupy a large space, resulting in a large geometric size of the drone, which is not convenient for the transportation and storage of multi-rotor unmanned aerial vehicles; The arm can reduce the overall size of the drone. However, the folding structure of the existing folding arm is relatively complicated, and the operation is relatively cumbersome, which aff...
