Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to an anti-interference structure of a unmanned aerial vehicle. Background Art

[0002] UAVs are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by onboard computers. UAVs can also be classified in many ways according to size, activity radius and mission altitude. The anti-interference structure of UAVs is a specially designed structure to improve the anti-interference ability of UAVs in complex electromagnetic environments and ensure their stable and reliable mission execution;

[0003] However, when the fan blades of the drone rotate at high speed, they generate friction with the surrounding air. This friction causes the charge to be redistributed between the fan blades and air molecules, forming static electricity. In addition, in a dry environment, due to the low moisture content in the air, static electricity is more likely to form and remain on the drone. Long-term static electricity discharge may cause damage to the drone's communication data interface, thereby affecting the normal operation of the drone.

[0004] In order to solve the above problems, this application proposes an anti-interference structure of a drone. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-3 An anti-interference structure of a drone comprises a drone body 1, a propeller of the drone body 1 is provided with an anti-static structure 2, the anti-static structure 2 comprises a connector 201 mounted on the drone body 1, the propeller of the drone body 1 comprises a propeller blade, a shaft, and a mounting plate, wherein the propeller blade is connected to the drone body 1 through the mounting plate, wherein there are four anti-static structures 2, and each anti-static structure 2 is respectively distributed on the four propellers of the drone body 1.

[0027] A connecting plate 202 is installed on the outer wall of the connecting piece 201. The outer wall of the connecting plate 202 is close to the propeller of the drone body 1. There is a certain distance between the connecting plate 202 and the shaft rod of the drone body 1, which effectively prevents the connecting plate 202 from affecting the operation of the drone body 1. A protective cover 204 is installed on the bottom wall of the connecting piece 201. The top wall of the protective cover 204 is fixedly connected to the bottom wall of the drone body 1. A first discharge needle 203 is provided on the bottom wall of the connecting piece 201. The first discharge needle 203 is located inside the protective cover 204. The protective cover 204 provided has a certain protective effect on the first discharge needle 203.

[0028] The outer wall of the first discharge needle 203 is connected to the inner wall of the protective cover 204, and a balance board 205 is installed on the bottom wall of the first discharge needle 203. The bottom wall of the balance board 205 is provided with a second discharge needle 206. The second discharge needle 206 is distributed at the bottom position of the balance board 205. The static electricity generated on the propeller of the drone body 1 is absorbed through the connecting plate 202, and then transmitted to the second discharge needle 206 through the connecting piece 201, the first discharge needle 203, and the balance board 205 for discharge processing.

[0029] A third discharge needle 3 is installed on the inner wall of the connecting plate 202, and the outer wall of the third discharge needle 3 is fixedly installed with the inner wall of the connecting piece 201. The third discharge needle 3 is L-shaped and is placed inside the connecting plate 202 and the connecting piece 201. The static electricity on the drone body 1 is absorbed by the third discharge needle 3. Due to the shape of the discharge needle, it can be more concentrated and accurately pointed to the area where static electricity needs to be eliminated. This feature makes the discharge needle more effective in dealing with static electricity problems in specific areas. The material of the connecting piece 201 and the connecting plate 202 is set to anti-static material, which effectively improves the discharge effect of the third discharge needle 3.

[0030] One end of the third discharge needle 3 adjacent to the connecting plate 202 is not connected to the propeller of the drone body 1, and one end of the third discharge needle 3 away from the connecting plate 202 is slidably connected to the inner wall of the first discharge needle 203. By setting the first discharge needle 203, static electricity on the third discharge needle 3 is absorbed and then released through the first discharge needle 203.

[0031] Reference Figure 3-4 The bottom wall of the drone body 1 is installed with an electric telescopic rod 4, the output end of the electric telescopic rod 4 is fixedly connected to the top wall of the balance board 205, the outer wall of the first discharge needle 203 is slidably connected to the inner wall of the connector 201, and the position where the electric telescopic rod 4 connects to the balance board 205 is provided with an anti-static material to effectively avoid the influence of static electricity on the electric telescopic rod 4. The electric telescopic rod 4 is started, and the output end of the electric telescopic rod 4 drives the balance board 205 to move. At this time, the outer wall of the first discharge needle 203 slides with the inner wall of the connector 201, and the inner wall of the first discharge needle 203 slides with the outer wall of the third discharge needle 3.

[0032] A metal plate 5 is installed on the side of the balance plate 205 away from the electric telescopic rod 4, and the outer wall of the metal plate 5 is connected to the outer wall of the first discharge needle 203. The side of the metal plate 5 away from the balance plate 205 is fixedly connected to the top wall of the second discharge needle 206. The static electricity on the first discharge needle 203 is quickly absorbed by the set metal plate 5 and discharged through the second discharge needle 206.

[0033] A protective cover 7 is installed on the bottom wall of the drone body 1, and the bottom wall of the protective cover 7 is fixedly connected to the top wall of the balance board 205. The electric telescopic rod 4 is located inside the protective cover 7. The material of the protective cover 7 is anti-static material, which further avoids the influence of static electricity on the electric telescopic rod 4.

[0034] A circular plate 6 is installed on the bottom wall of the protective cover 204, and the inner wall of the circular plate 6 is slidably connected to the outer wall of the second discharge needle 206. The circular plate 6 is provided with the same number of symmetrical notches as the second discharge needle 206. After the electric telescopic rod 4 is started, the circular plate 6 serves as a balance for the movement of the second discharge needle 206.

[0035] Working principle:

[0036] After the drone body 1 is running, the electric telescopic rod 4 is started at the same time, and the output end of the electric telescopic rod 4 drives the balance plate 205 to move downward, and the balance plate 205 drives the second discharge needle 206 to pass through the circular plate 6 and be exposed to the air. The friction between the propeller of the drone body 1 and the air generates static electricity that remains on the drone body 1 and is absorbed by the third discharge needle 3 to the first discharge needle 203. The first discharge needle 203 discharges the static electricity to the metal plate 5, and then transmits it to the second discharge needle 206 through the metal plate 5. The static electricity is discharged through the second discharge needle 206, which effectively avoids damage to the drone communication data interface due to static electricity, thereby effectively preventing the drone from being unable to operate normally.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
