Vehicle-mounted unmanned aerial vehicle cantilever passive unfolding mechanism and unfolding method thereof

The vehicle-mounted unmanned aerial vehicle cantilever passive unfolding mechanism comprises a fuselage and two driving mechanisms, a guide groove is formed in the fuselage, two cantilevers are connected to the two ends of the fuselage correspondingly, the two cantilevers located at the same end are hinged through a pin shaft sleeve, and the two pin shaft sleeves are both in sliding connection with the guide groove; the two driving mechanisms are arranged in the guide grooves and can be driven by the two driving mechanisms to move face to face and back to back along the guide grooves, each driving mechanism comprises a telescopic rod, a driving head and an unfolding assembly, the unfolding assemblies are connected with the pin shaft sleeves, the telescopic rods are connected with the parking apron, the driving heads are connected with the telescopic rods, and when the telescopic rods extend, the driving heads can be driven to move to be connected with the unfolding assemblies; after the two driving heads are
