Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] Such as figure 1 A four-rotor UAV rack in an unfolded state is shown, figure 2 to its collapsed state. The frame of the four-rotor UAV mainly includes a frame body 1 made of carbon fiber plates and aluminum alloy connecting columns, a machine arm 2 made of square carbon fiber tubes, a motor base 21 made of carbon fiber plates, an elastic retractable landing gear 3, Arm self-locking folding part 4, tripod self-locking folding part 5, and detachable clamp 6. in, figure 2 The folded state of the frame of the UAV shown can be converted into figure 1 The expanded state shown.

[0020] image 3 It is an enlarged explanatory diagram of the arm self-locking folder 4 . Wherein the frame main body 1 made of carbon fiber board is provided with a slide groove 11 for directional sliding of the limit pin 42 . The square carbon fiber tube machine arm 2 is pressed toge...

Abstract

The invention belongs to the technical field of aircraft, in particular to a folding multi-rotor unmanned aerial vehicle frame. The folding multi-rotor unmanned aerial vehicle frame comprises a framemain body, an arm and a landing gear. The proximal end of the arm is articulated with the body, and the arm can be folded transversely with respect to the body; The distal end of the arm is hinged tothe landing gear which can be folded longitudinally relative to the arm. In addition, a self-locking mechanism for locking when the arm and landing gear are unfolded, a resilient telescopic landing gear for UAV take-off and landing cushioning, and a removable fixture for suspending the load device are included. The arm and the landing gear of the unmanned aerial vehicle can be folded, the volume occupation of the unmanned aerial vehicle is reduced, and the portability is enhanced. Resilient telescopic landing gear cushions the impact of UAV landing; Detachable fixtures allow users to quickly dismount and replace devices mounted on the drone, the portability and the task execution efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a frame device for a foldable multi-rotor unmanned aerial vehicle. Background technique [0002] Multi-rotor UAVs have good task adaptability and flexibility, and have developed rapidly in civil, industrial and military applications in recent years. The multi-rotor drone drives the rotor to generate lift through multiple motors distributed around the fuselage, and changes the attitude of the drone by adjusting the rotor speed. [0003] Constrained by the size of the motor and rotor of the multi-rotor UAV, the length of the arm extending out of the body is relatively long, which makes the space volume of the multi-rotor UAV relatively large, hindering its portability. It is a good solution to fold the arm of the multi-rotor UAV to reduce its volume in the storage state. [0004] At present, most of the structures of foldable UAVs are horizontal symmetrical folding o...
