Problems solved by technology

However, the torsion is generally relatively small, and it cannot firmly position the buttocks in a stable state. As a result, the arm is prone to swing when the arm is unfolded or folded and stored. For example, when the UAV is flying, the arm Due to the vibration of the propeller, the stability of the drone is not very good when flying

Abstract

An unmanned aerial vehicle and a machine frame thereof, related to an unmanned aerial vehicle technology. The unmanned aerial vehicle (1) comprises the machine frame (100), the machine frame (100) comprising a center body (110), comprising a mechanical arm connecting part (131) and a limiting part (135) provided on the mechanical arm connecting part (131), the mechanical arm connecting part (131)being provided with a shaft hole (132); and a mechanical arm (120), comprising an arm frame (121) and a limiting shaft (122) extended from one end of the arm frame (121), the limiting shaft (122) being inserted into the shaft hole (132) and capable of rotating within the shaft hole (132). A matching part (123) is provided on the limiting shaft (122), a motor mounting part (128) used for mounting apower motor of the unmanned aerial vehicle is provided at one end of the arm frame (121) away from the limiting shaft (122), where the arm frame (120) is rotatable relative to the center body (110),thus allowing the mechanical arm (120) to selectively be in a folded state or extended state.

Description

technical field [0001] The embodiment of the present invention relates to a drone technology. Background technique [0002] A traditional unmanned aerial vehicle with foldable arms includes a body and an arm mounted on the body. The arm rotates on the body to realize the unfolding and folding of the arm. After the arm is unfolded, it needs to be fixed to a certain angle. [0003] A conventional drone includes an arm and a body. The machine body is provided with a hinge, and the machine arm is arranged on the hinge. Through the hinge, a torsion force is generated between the machine arm and the machine body. form a limit. However, the torsion is generally relatively small, and it cannot firmly position the buttocks in a stable state. As a result, the arm is prone to swing when the arm is unfolded or folded and stored. For example, when the UAV is flying, the arm Due to the vibration of the propeller, the stability of the drone during flight is not very good. [0004] The...
