[0002] An unmanned aerial vehicle is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, and is widely used in fields such as aerial photography, agriculture, plant protection, express delivery, disaster rescue, mapping, power line inspection, etc. Small unmanned aerial vehicles can be used for people's daily entertainment.

[0003] In existing unmanned aerial vehicles, some do not have a housing installed at the rotor position to protect the rotor. When used in places with obstacles such as branches, it is easy to cause the unmanned aerial vehicle to crash. Some unmanned aerial vehicles are equipped with a housing, but generally the housing is fixed to the unmanned aerial vehicle. When used in some flat areas, the unmanned aerial vehicle with a housing has a greater gravity, undoubtedly a greater power consumption, reducing the service life of the unmanned aerial vehicle and also reducing the use experience. At the same time, when the unmanned aerial vehicle is folded up and not in use, in order to facilitate storage, generally the rotors of the unmanned aerial vehicle are set to an overlapping structure, but during storage, the rotors of the unmanned aerial vehicle cannot be isolated and protected. Content of the Utility Model

Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The technical solution provided by the present invention is as follows: As Figures 1 to 5 shown, in this embodiment, a UAV rotor cover structure includes a UAV body 1. Mounting rods 2 are symmetrically and fixedly installed at the four corners of the UAV body 1. A rotor assembly 3 is installed at the end of the mounting rod 2. A storage cover 4 is installed outside the mounting rod 2. The storage cover 4 can be slidably sleeved outside the mounting rod 2 and the rotor assembly 3. An isolation cover housing 5 for isolating the rotor assembly 3 is slidably installed outside the mounting rod 2. The isolation cover housing 5 is detachable. By overlapping the rotors on the rotor assembly 3 directly above the mounting rod 2, then sliding the storage cover 4 to the outside of the mounting rod 2 and the rotor assembly 3 and fixing the position of the storage cover 4, the storage cover 4 will isolate and protect the rotor assembly 3, facilitating the storage of the UAV. Install the isolation cover housing 5 outside the mounting rod 2 and the rotor assembly 3, and drive the isolation cover housing 5 to be stably installed outside the mounting rod 2. The isolation cover housing 5 is used to protect the rotor assembly 3 to prevent the problem that the rotor assembly 3 contacts an obstacle during the use of the UAV and causes the UAV to fall.

[0022] As Figures 1 to 5 shown, a sliding hole 6 is opened at the bottom end of the end of the storage cover 4. An insertion rod 7 is slidably installed inside the sliding hole 6. A compression spring 8 is sleeved outside the bottom end of the insertion rod 7. One end of the compression spring 8 is fixedly connected to the bottom end of the insertion rod 7, and the other end of the compression spring 8 is fixedly connected to the lower surface of the storage cover 4. An insertion hole 9 corresponding to the position of the insertion rod 7 is opened on the lower surface of the mounting rod 2. The insertion hole 9 is slidably connected to the insertion rod 7.

[0023] Then slide the storage cover 4 to the outside of the mounting rod 2 and the rotor assembly 3. The lower surface of the mounting rod 2 will squeeze the bottom end of the insertion rod 7, driving the insertion rod 7 to slide inside the sliding hole 6. At this time, the compression spring 8 is in a stretched state. When the storage cover 4 moves to the final position, the pulling of the bottom end of the insertion rod 7 by the compression spring 8 will drive the insertion rod 7 to rise inside the sliding hole 6, and the insertion rod 7 will insert into the insertion hole 9 to fix the position of the storage cover 4.

[0024] As Figures 1 to 5 shown, a rounded corner 10 is opened at the top of the insertion rod 7.

[0025] When the storage cover 4 is slid to the outside of the mounting rod 2 and the rotor assembly 3, the rounded corner 10 at the top of the insertion rod 7 is arranged to be able to squeeze against the end of the mounting rod 2, which can facilitate the sliding of the insertion rod 7. At the same time, when the storage cover 4 is removed from the outside of the mounting rod 2 and the rotor assembly 3, the insertion rod 7 can be easily slid out of the insertion hole 9 by squeezing the rounded corner 10 at the top of the insertion rod 7 against the insertion hole 9.

[0026] As Figures 1 to 5 shown, a sponge pad is installed inside the inner cavity of the storage cover 4.

[0027] When the storage cover 4 is installed on the outside of the mounting rod 2 and the rotor assembly 3, the provided sponge pad can prevent the inner cavity of the storage cover 4 from being squeezed and worn by the rotor assembly 3.

[0028] As Figures 1 to 5 shown, rotating shafts 11 are symmetrically and rotatably installed on both sides of the mounting rod 2 corresponding to the middle of the isolation cover housing 5. Connecting rods 12 are fixedly installed on the outer sides of the rotating shafts 11. A positioning rod 13 is fixedly installed at one end of the connecting rod 12 away from the rotating shaft 11. A torsion spring 14 is sleeved on the outer side of the top end of the rotating shaft 11. One end of the torsion spring 14 is fixedly connected to the top of the connecting rod 12, and the other end of the torsion spring 14 is fixedly connected to the inner wall of the isolation cover housing 5. Positioning holes 15 are opened on both sides of the mounting rod 2, and the positioning holes 15 are slidably connected with the positioning rods 13. End caps 16 are fixedly installed at both ends of the rotating shaft 11, and the end caps 16 are arranged on the upper and lower surfaces of the mounting rod 2.

[0029] The isolation cover housing 5 is installed on the outside of the mounting rod 2 and the rotor assembly 3. The rotating shaft 11 connected to the positioning rod 13 will be rotated by the extrusion of the end of the mounting rod 2, and the positioning rod 13 will be located on both sides of the mounting rod 2. At this time, the torsion spring 14 is in a twisted state. Then, the positioning rod 13 is slid to the position of the positioning hole 15. The rotation of the rotating shaft 11 by the torsion spring 14 will drive the positioning rod 13 to slide into the positioning hole 15. The positioning of the end caps 16 with the upper and lower surfaces of the mounting rod 2 will drive the positioning rod 13 to be stably stored in the positioning hole 15, and will drive the isolation cover housing 5 to be stably installed on the outside of the mounting rod 2.

[0030] As Figures 1 to 5 shown, a chamfer 17 is opened at the opening of the positioning hole 15.

[0031] It is convenient for the positioning rod 13 to slide into the positioning hole 15.

[0032] The present utility model provides a drone rotor cover structure, and the specific working principle is as follows:

[0033] When the device is in use and the drone is not in use, by overlapping the rotors on the rotor assembly 3 directly above the mounting rod 2, and then sliding the storage cover 4 to the outside of the mounting rod 2 and the rotor assembly 3, the lower surface of the mounting rod 2 will squeeze the bottom end of the insertion rod 7, driving the insertion rod 7 to slide inside the sliding hole 6. At this time, the compression spring 8 is in a stretched state. When the storage cover 4 moves to the final position, the pulling of the bottom end of the insertion rod 7 by the compression spring 8 will drive the insertion rod 7 to rise inside the sliding hole 6, and the insertion rod 7 will insert into the insertion hole 9 to fix the position of the storage cover 4. At this time, the storage cover 4 will isolate and protect the rotor assembly 3, and the drone can be stored;

[0034] When the drone is used in some places with obstacles such as branches, the isolation cover 5 is installed on the outside of the mounting rod 2 and the rotor assembly 3. The rotating shaft 11 connected to the positioning rod 13 will be squeezed by the end of the mounting rod 2 and rotate. The positioning rod 13 will be on both sides of the mounting rod 2. At this time, the torsion spring 14 is in a twisted state. Then, the positioning rod 13 is slid to the position of the positioning hole 15. The rotation of the rotating shaft 11 by the torsion spring 14 will drive the positioning rod 13 to slide into the positioning hole 15. The positioning of the end cover 16 with the upper and lower surfaces of the mounting rod 2 will drive the positioning rod 13 to be stably stored inside the positioning hole 15, driving the isolation cover 5 to be stably installed on the outside of the mounting rod 2, and the isolation cover 5 is used to protect the rotor assembly 3.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
