Vehicle-mounted unmanned aerial vehicle net bumping recovery device

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and relates to a vehicle-mounted unmanned aerial vehicle net bumping recovery device which comprises stand columns, connecting rod type synchronization mechanisms, damping mechanisms, supporting arms, a recovery net, oscillating bars and a vehicle platform. The two supporting arms are symmetrically and obliquely fixed to the vehicle platform; the stand columns are vertically downwards fixed to the top ends of the supporting arms in the vertical direction. One connecting rod type synchronization mechanism is fixed to the top end of each stand column; each connecting rod type synchronization mechanism is composed of a mechanism main rod, a first oscillating arm and a second oscillating arm, wherein the first oscillating arm and the second oscillating arm are fixed to the two ends of the mechanism main rod through rotating shafts, and the first oscillating arm and the second oscillating arm are connected together through a connecting rod. The top end of each first oscillating arm and the top end of each second oscillating arm are each connected with one oscillating bar, and the recovery net is fixed to the ends of the four oscillating bars. A nose of an unmanned aerial vehicle rushes at the net face of the recovery net 6 in the direction from a vehicle head to a vehicle tail. Wings of the unmanned aerial vehicle generate pull force to the recovery net 6 and drive the oscillating bars 7 to move to transmit the force to the stand columns 1; at last, the damping mechanisms 3 connected with the stand columns 1 complete energy absorption, and the unmanned aerial vehicle is safely recovered.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a vehicle-mounted unmanned aerial vehicle collision net recovery device. Background technique [0002] The landing method of the existing UAV system generally adopts sliding landing or belly wipe landing, and the landing of the UAV requires the UAV to be equipped with a landing gear. The weight of the landing gear structure greatly reduces the effective use of the UAV. Load capacity; and the taxiing landing requires a long and flat runway, and its use in complex terrain mountains or ships is greatly restricted. The UAV is subjected to a large impact load when it touches the ground with the belly wipe landing method, especially when the landing attitude deviates or the ground is hard, it is likely to cause damage to the UAV body structure, which greatly shortens the UAV. service life.
