The invention discloses a driving device, a seat assembly and a vehicle with the seat assembly. The driving device comprises a shell, a driving assembly and a driving assembly, the limiting piece is provided with a first limiting part; an eccentric shaft is formed on the end face of the input gear; the planetary gear is provided with a second limiting part matched with the first limiting part, and the planetary gear rotates around the axis of the eccentric shaft under the constraint of the limiting piece; the output part and the input gear rotate coaxially; a reinforcing protrusion and/or a reinforcing groove extending in the radial direction are/is formed in the peripheral face of the eccentric shaft. According to the driving device, by arranging the input gear, the planetary gear and the output part, a transmission system with the smaller size is formed, the planetary gear is limited through the eccentric shaft and the limiting piece, the locking strength of the driving device is improved, and the problems that a lifting motor reduction gearbox of an automobile seat is large in size and insufficient in locking strength are solved.

    本发明公开了一种驱动装置、座椅组件和具有其的车辆,所述驱动装置包括:壳体;限位件,所述限位件上设置有第一限位部;输入齿轮,所述输入齿轮端面上形成有偏心轴;行星齿轮,所述行星齿轮上设置有与所述第一限位部配合的第二限位部,所述行星齿轮在所述限位件的约束下绕所述偏心轴的轴线转动;输出部,所述输出部与所述输入齿轮同轴转动;所述偏心轴的外周面上形成有沿径向延伸的加强凸起和/或加强槽。根据本发明的驱动装置通过设置输入齿轮、行星齿轮、输出部,形成了体积更小的传动系统,且通过偏心轴、限位件对行星齿轮进行限位,提升了驱动装置的锁止强度,解决了汽车座椅的抬升电机减速箱体积较大,锁止强度不足的问题。
