Description

Technical Field

[0001] The utility model relates to the technical field of protection equipment, in particular to a protection structure for an unmanned aerial vehicle (UAV). Background Art

[0002] A drone, or unmanned aerial vehicle, is an aircraft that does not require direct human control and is typically controlled by a ground control station via wireless signals. Drones can be used for a variety of purposes, including aerial photography, surveying and mapping, precision agriculture, search and rescue, and logistics. The design and functions of drones vary depending on their purpose and technical specifications. A drone protective structure refers to a design structure used to protect drones from damage during flight, transportation, or landing.

[0003] Most existing drone protection structures only use shock-absorbing support structures to offset the damage to the drone body caused by landing or vibration. However, in actual use, the drone's rotor is at the very edge of the equipment and is most susceptible to damage due to tilted landing or collision. A single shock-absorbing protection structure is difficult to meet actual usage needs. Utility Model Content

[0004] The purpose of the present utility model is to provide a drone protection structure in order to solve the problem that most existing drone protection structures only use a shock-absorbing support structure to offset the damage to the drone body caused by landing or vibration. However, during actual use, the rotor of the drone is at the very edge of the equipment and is most likely to be damaged due to tilting landing or collision. The single shock-absorbing protection structure is difficult to meet the actual use needs.
