Disclosed is a gear driving device for automotive movable parts. The gear driving device comprises a motor (100) and a driver gearbox (200). The driver gearbox comprises multiple stages of planetary gear assemblies (1, 2) connected in series and a gear assembly (3) with few teeth number difference. A first-stage planetary gear assembly in the multiple stages of planetary gear assemblies is connected to the motor; and the last-stage planetary gear assembly in the multiple stages of planetary gear assemblies is connected to the gear assembly with few teeth number difference. The gear driving device has the advantages of small volume, light weight and high working efficiency.
A gear driving device for an automotive movable part, the gear driving device comprising a motor and a driver gearbox, wherein the driver gearbox includes at least two stages of planetary gear assemblies connected in series and a small tooth difference gear assembly, wherein a first stage planetary gear assembly of the at least two stages of planetary gear assemblies is connected to the motor, and a last stage planetary gear assembly of the at least two stages of planetary gear assemblies is connected to the small tooth difference gear assembly.
