Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) frame technology, and in particular to a simple UAV leg connection structure. Background Technology

[0002] A drone is an unmanned aerial vehicle controlled by a remote control or autonomous program. A simple drone is an unmanned aerial vehicle with a simple structure that is easy to manufacture and operate. They are usually used for educational and entertainment purposes, but they are also suitable for some basic civilian and commercial applications, such as aerial photography, agricultural monitoring, and environmental data collection. The legs of a simple drone are an important part of the drone, which are used to provide support and stability during takeoff, landing, and parking. The drone legs need a connecting structure to fix the drone legs to the drone frame.

[0003] There are still some problems in the use of existing simple drone leg connection structures. Complex connection structures may increase the difficulty of manufacturing and assembly, increase production costs, require more time and manpower for assembly, and extend the production cycle. Therefore, those skilled in the art provide a simple drone leg connection structure to solve the problems mentioned in the background art. Utility Model Content
