Unmanned aerial vehicle and arm folding structure thereof

Abstract

The invention discloses an unmanned aerial vehicle and an arm folding structure thereof. The arm folding structure comprises an airframe and a telescopic arm, wherein a locking and limiting part is arranged on the airframe; the telescopic arm comprises a fixing part, a mobile part and a pop-up part arranged between the fixing part and the mobile part, the mobile part and the fixing part are connected in a sliding mode, the fixing part is hinged to the airframe, the mobile part is provided with a locking and matched part, and the locking and limiting part is used for being matched with the locking and matched part under the action of the pop-up part to make the telescopic arm keep a spread attitude; during spreading, the telescopic arm is rotated to make the locking and matched part get close to the locking and limiting part until the locking and matched part and the locking and limiting part are matched and locked; during folding, the mobile part is pushed to make the telescopic arm contract and to make the locking and matched part detached from the locking and limiting part, and then the telescopic arm is rotated toward a direction of the airframe to complete folding of the telescopic arm. Therefore, no need to fix the arm folding structure with an additional part is achieved, so that detaching or installing the part during spreading or folding is avoided, operation is convenient, and not only is the efficiency improved, but also the lost of the part is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle and its arm folding structure. Background technique [0002] With its simple structure and stable flight attitude, multi-rotor drones are more and more popular among consumers. However, compared with other UAVs, multi-rotor UAVs usually connect the propellers to the fuselage through the arms. In order to ensure that the propellers do not interfere with each other and provide sufficient lift, the arms must have a certain length. It takes up a lot of space with the propeller, which is not conducive to storage and storage. [0003] In order to achieve the purpose of easy storage and storage, multi-rotor drones usually adopt the form of foldable arms, that is, the arms are rotatably connected to the fuselage, so that the arms can be expanded or folded relative to the fuselage. In the unfolded state, The machine arm is fixed by screws pass...

However, compared with other UAVs, multi-rotor UAVs usually connect the propellers to the fuselage through the arms. In order to ensure that the propellers do not interfere with each other and provide sufficient lift, the arms must have a certain length. It takes up a lot of space with the propeller, which is not conducive to storage and storage

[0003] In order to achieve the purpose of easy storage and storage, multi-rotor drones usually adopt the form of foldable arms, that is, the arms are rotatably connected to the fuselage, so that the arms can be expanded or folded relative to the fuselage. In the unfolded state, The machine arm is fixed by screws passing through the through holes on the machine arm and the machine body. When the machine arm is put away, the screws need to be removed first. The arms need to be disassembled and assembled with screws, which is cumbersome to operate and the screws are easy to lose, which is inconvenient to store
