Automatic door opening device and refrigerator
The invention provides an automatic door opening device and a refrigerator. The automatic door opening device comprises a driving assembly, a clutch device, a first gear set and a first rack push rod, wherein the driving assembly comprises a worm; the clutch device comprises a master gear, a shifting rod and a sub gear; the master gear comprises a worm gear and a transmission gear which rotate coaxially, the worm gear is meshed with the worm, and the transmission gear is meshed with the sub gear; the first rack push rod comprises a first rack, and the first rack is meshed with the gear set; and the clutch device is located between the driving assembly and the first gear set. When the clutch device is in an initial state, the sub gear is not meshed with a first duplicate gear; the driving assembly is driven, so that the worm drives the worm gear and the transmission gear to rotate together, the worm gear drives the shifting rod to rotate, the sub gear is meshed with the first gear set, and the first gear set rotates to push the first rack push rod to stretch out to open the door body.
本发明提供一种自动开门装置和冰箱，包括：驱动组件，包括蜗杆；离合装置，包括母齿轮、拨杆和子齿轮，所述母齿轮包括同轴转动的蜗轮和传动齿轮，所述蜗轮与所述蜗杆啮合，所述传动齿轮与所述子齿轮啮合；第一齿轮组；以及第一齿条推杆，所述第一齿条推杆包括第一齿条，所述第一齿条啮合于所述齿轮组；其中，所述离合装置位于所述驱动组件与所述第一齿轮组之间；所述离合装置处于初始状态时，所述子齿轮未啮合所述第一双联齿轮；驱动所述驱动组件，使得所述蜗杆带动所述蜗轮和所述传动齿轮一起转动，所述蜗轮带动所述拨杆转动，使得所述子齿轮啮合所述第一齿轮组，所述第一齿轮组转动推动所述第一齿条推杆伸出打开所述门体。
