Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a portable unmanned aerial vehicle. Background Art

[0002] As we all know, drones are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or they can be operated completely or intermittently autonomously by an onboard computer. After years of technological accumulation and rapid economic development, drones are now used in more and more scenarios, such as aerial photography, crop monitoring, vegetation protection, selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, and filming, etc.

[0003] The arms and frames of existing drones are fixedly connected to the fuselage, which causes the equipment to take up a lot of space when being carried, making it inconvenient to carry. At the same time, when the equipment is squeezed during carrying, the arms are easily damaged and broken, causing a lot of damage. As a result, the arms and frames of the drone are not easy to fold when being carried, resulting in a lot of space being taken up when carrying, and are easily squeezed and damaged. The frame will also increase air resistance during flight, so there is room for improvement. Utility Model Content
