Description

Technical Field

[0001] The present application relates to the field of unmanned aerial vehicle equipment, and in particular to an attitude stabilization platform for vertical take-off and landing of unmanned aerial vehicles. Background Art

[0002] The attitude stabilization platform is an important equipment for ship-borne and vehicle-borne unmanned take-off and landing. Through the control system, the UAV take-off and landing platform can maintain a horizontal state during the movement of ships and vehicles, ensuring the requirements for UAV take-off and landing.

[0003] The test laboratory used for the existing attitude stabilization platform currently adopts a structure of multiple sets of electric push rods to achieve the stability of the platform's attitude. However, there is motion coupling between the electric push rods in the structure, and the movement of each electric cylinder needs to be accurately controlled by the control system. When one of the electric cylinders has a problem, the entire platform will not work and the electric cylinders will be stuck. At the same time, the commonly used electric push rods are telescopic movements and have poor adaptability to high dust environments. Once the push rods are exposed to high dust and high salt fog natural environments, they are prone to corrosion and jamming. Summary of the invention

[0008] The mounting frame 5 is based on a group installation of multiple drive modules to achieve attitude stability control.

[0009] Optionally, the frame 2 is hinged to the base 1 via a rotating shaft assembly.
