Description

Technical Field

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an onboard computer. A drone is an aircraft managed by a control station. A drone is usually composed of a fuselage, wings, a tripod, a power system, a control system, and a communication system. When the drone lands and parks, the tripod provides stable support to ensure that the drone maintains balance in various ground environments and prevents tipping or sliding. The tripod can act as a buffer when the drone lands, reducing the impact force between the fuselage and the ground, thereby protecting the drone's internal electronic equipment and structural components.

[0003] The currently used tripod is fixedly connected to the fuselage, and the fixed tripod may also cause inconvenience during transportation and storage.
