The invention discloses a vehicle-mounted large unmanned helicopter hoisting device which comprises a pair of suspension arm mechanisms fixed to the middle of the lower side of a cabin top wall, a hoisting mechanism located on the lower sides of the suspension arm mechanisms and a hoisting bracket for supporting a large unmanned helicopter, and each suspension arm mechanism comprises a fixed arm, a movable arm, a hanging bracket mechanism and a movable arm and hanging bracket moving mechanism. The hoisting mechanism comprises a hoisting cross beam, a hoisting transmission shaft, a hoisting transmission motor speed reducer combination, a speed reducer coupler, two hoisting rollers, two hoisting steel wire ropes, two hoisting transmission shaft bearing seats and two hoisting transmission couplings; and two front wheels and a rear wheel of the large unmanned helicopter are locked on the hoisting bracket through a front wheel locking frame and a rear wheel locking frame respectively. The lifting device is compact in structure, high in lifting precision, small in occupied space, large in bearing capacity, long in stroke and good in stability. The unfolding and folding speed of the suspension arm mechanism is obviously improved, and a reliable guarantee is provided for improving the emergency response speed of the large unmanned helicopter.
