Description

Technical Field

[0001] The utility model relates to the technical field of protection mechanisms for unmanned aerial vehicles (UAVs), in particular to a protection mechanism for an agricultural UAV. Background Art

[0002] Agricultural drones are unmanned aerial equipment, mainly used in agricultural production, such as spraying pesticides, sowing, fertilizing and other operations. Agricultural drones will impact the ground when landing, which may cause the agricultural drones to collide, so protective agencies are needed to protect them.

[0003] According to a description of a drone protection mechanism disclosed on the Patent Network (Grant Publication No.: CN 209337011U), "The present utility model discloses a drone protection mechanism, comprising a flight control computer, wherein the four corners of the flight control computer surface are fixedly connected to a frame, the outer side of the frame is fixedly connected to a motor, and the surface of the motor output shaft is sleeved with a rotor. The present utility model uses an anti-collision mechanism to prevent the top of the flight control computer from being damaged by impact with buildings. At the same time, the fall protection mechanism reduces the impact force with the ground after an accidental fall of the flight control computer. At the same time, the balance protection mechanism ensures that the flight control computer lands smoothly after landing. In combination with the fall protection mechanism, the flight control computer can land stably on unstable ground, thus solving the problem that existing drones lack corresponding protection measures. The drone protection mechanism has the advantages of effective protection, improves safety in use, is not easily damaged by impact, and increases the service life of the drone."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use of the utility model, the device compresses the third spring through the sponge plate and compresses the second spring through the first sponge plate to absorb the impact of landing. However, when the drone carries items, its own gravity increases and it lands on an inclined area. Since the position angle of the telescopic rod of the device is fixed, it cannot stabilize the inclined device, which will cause the drone to tilt and roll over after landing. Therefore, it is necessary to improve a protective mechanism for agricultural drones to solve the above problems. Utility Model Content
