Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) frame technology, and in particular to a connecting structure for a double-triangle stacked UAV wing rod. Background Technology

[0002] A drone is an unmanned aerial vehicle controlled by remote control or autonomous programs. It is widely used in military, civilian and commercial fields. A double-triangle stacked drone is composed of two triangular structures stacked together. This design aims to optimize the drone's flight performance, stability, payload capacity and portability. The wing rod of this type of drone needs to be connected using a connecting structure during the connection process to ensure the stability between the drone's wing rod and the drone frame.

[0003] Some problems still exist in the use of existing double-triangle stacked UAV wing connection structures. During flight, especially at high speeds or when encountering strong airflow, the wing rod connection may be subjected to large stresses, leading to loosening or breakage of the connection structure. Therefore, those skilled in the art have provided a double-triangle stacked UAV wing rod connection structure to solve the problems mentioned in the background art. Utility Model Content
