[0002] With the rapid development of drones, drones can be seen in many occasions, and the people who control drones are no longer limited to professional players. The safety of drones is particularly important. Drones have the risk of endangering personal safety and the risk of the aircraft itself colliding when flying at high speeds, so it is necessary for drones to adopt corresponding rotor protection structures.

[0003] At present, the rotor protection frame structure in the prior art is generally circular, and is protected by surrounding the rotor. However, this protection structure increases the overall size of the drone and makes it difficult to store the rotor of the drone, thus easily affecting the carrying of the drone.

[0004] Therefore, the present application provides a UAV rotor protection structure to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a UAV rotor protection structure to solve the problem that the UAV protection structure of the existing UAV makes it difficult to store the rotor, thereby affecting the carrying capacity of the UAV.

[0007] A drone rotor protection structure comprises a fixing seat for fixing to the bottom end of the drone rotor, a rotating ring is rotatably mounted on the fixing seat, a positioning column is elastically mounted on the side of the rotating ring, the positioning column is plugged into and matched with the edge of the fixing seat, horizontal extension frames are commonly fixed on both sides of the rotating ring, the extension frame horizontally extends out of the bottom end of the drone rotor and is elastically mounted with a buffer frame, two movable connecting pieces are symmetrically mounted on one side of the buffer frame away from the extension frame, and a protective rod is fixed to one end of the two connecting pieces away from the buffer frame.

[0008] Optionally, a mounting tube is fixed in the middle of the fixing seat, a fastening screw hole is opened in the middle of the mounting tube, a bolt is fitted in the fastening screw hole, and the fixing seat is fixed to the lower end of the UAV rotor.

[0009] Optionally, the rotating ring is rotatably mounted on the mounting tube, and the positioning column is elastically mounted in the rotating ring through a spring and extends horizontally out of the outside of the rotating ring.

[0010] Optionally, positioning blocks are symmetrically fixed to both side edges of the fixing seat, and a positioning hole for inserting the positioning column is formed in the middle of the positioning block.

[0011] Optionally, a plurality of horizontal movable columns are fixed on one side of the buffer frame facing the extension frame, the movable columns penetrate into the extension frame, and a buffer spring is sleeved on the movable columns, one end of the buffer spring is connected to the extension frame, and the other end is connected to the buffer frame.

[0012] Optionally, the ends of the two protective rods facing each other are detachably connected and joined together, and the two protective rods are connected to form a semi-annular protective structure around the outside of the UAV rotor.

[0013] Optionally, docking ears are fixed on the opposite sides of the two protective rods, the two docking ears are butt-fitted, and a fixing screw is fixed in the middle of one docking ear, the fixing screw passes through the middle of the other docking ear, and is fixed with a nut.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, thanks to the cooperation of the fixed seat, rotating ring, extension frame, buffer frame and protective rod, the two protective rods can be connected and surrounded by the outside of the drone rotor for protection, and through the elastic connection between the extension frame and the buffer frame, the protective rod also has a certain buffering effect, which can further improve the protection effect of the drone rotor.

[0016] At the same time, thanks to the rotating setting of the rotating ring on the fixed seat and the detachable docking of the two protective bars, the two protective bars can be easily rotated and stored to both sides of the buffer frame, and then the rotating ring, extension frame and buffer frame can be rotated and stored as a whole under the frame of the drone rotor, so that they can be stored when not in use, which is convenient for the storage and carrying of the drone.

[0017] In summary, the utility model not only has a good protective effect of elastic buffering, but also can be conveniently stored under the frame of the UAV rotor, which is conducive to the storage and carrying of the UAV and has a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
