The invention discloses a variable-speed coupling device of an oil-electricity hybrid power system, which realizes gear transmission output under different transmission ratios by arranging a double-planet carrier structure in a coupling box body, arranging planet wheels and a sun wheel on the double-planet carrier structure and a middle inner shaft respectively, adopting the planet wheels and the sun wheel for transmission and meshing the planet wheels with different gear ring structures. The brake in the coupling box body brakes the gear ring, so that the meshing transmission locking process of different planet gears is achieved, the different gear rings are fixed by connecting the brake to achieve input and output of different power sources, torques and rotating speeds, the transmission structure is stable, control is stable, an effective coupling structure is provided for dual-output control of an oil-electricity hybrid power system, and the service life of the oil-electricity hybrid power system is prolon
