The present invention relates to a gearbox assembly comprising a housing, a cover, a screw rod that is inserted through said housing along a first direction, a worm wheel integrally formed on said screw rod, and a worm arranged in the housing along a second direction perpendicular to the first direction, said worm being in meshing transmission with the worm wheel, wherein said worm is driven into rotation by a driving shaft, so that the worm drives said worm wheel and said screw rod into rotation through a kinetic pair; said screw rod moves a lifting mechanism attached to the screw rod in a vertical direction through screw transmission; and a stop pin is arranged on said housing, said stop pin being positioned in the direction of extension of a free end of the driving shaft of the worm against the free end. In addition, the present invention further relates to a headrest actuator comprising said gearbox assembly.
