Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] see Figure 1-7 , the present invention provides a technical solution: a multi-rotor folding drone, including a drone body 1, the top of the drone body 1 is fixedly connected with a connecting shaft 2, and the surface of the connecting shaft 2 is hinged with a drone The wing 3, by setting one end of the drone wing 3 to be hinged to the surface of the connecting shaft 2, achieves the effect of rotating and folding the drone wing 3, reducing the volume oc...

Abstract

The invention discloses a multi-rotor folding unmanned aerial vehicle, which comprises an unmanned aerial vehicle body; A positioning groove is provided on the upper surface of the wing, and a helical column is inserted into the positioning groove, and the positioning groove and the helical column are fixedly connected by fixing bolts, and the surfaces of the fixing bolts are respectively sleeved with a first gasket and a second gasket. The multi-rotor folding UAV of the present invention achieves the effect of rotating and folding the wings of the UAV, reduces the volume occupied by the UAV, and achieves the effect of rotating and folding the helical wing, thereby reducing the volume occupied by the helical wing. It can lubricate the rotating balls and balls in the rotating chamber and enhance the flexibility, so that the folding effect of the spiral wing is better, and it can effectively avoid the problem that the rotating ball cannot be positioned stably after rotating and unfolding, thus solving the problem of multi-rotor UAV transportation When the fuselage is damaged due to its large size.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor folding unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parawing aircraft, etc. [0003] According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civil use, drones plus industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, selfies, express delivery, disaster rescue, wildlife ob...
