Automatic door opening and closing mechanism and refrigerator using automatic door opening and closing mechanism
The invention relates to an automatic door opening and closing mechanism and a refrigerator using the automatic door opening and closing mechanism. The automatic door opening and closing mechanism comprises a power source capable of forwards and reversely rotating to output power, a telescopic driving assembly suitable for driving a refrigerator door body to be opened and closed relative to a refrigerator body; the telescopic driving assembly comprises a screw in transmission connection with the power source, a nut in transmission connection with the screw and a telescopic rod connected with the nut in a matched mode; a clutch groove is formed in the telescopic rod, and a clutch clamping hook suitable for being embedded in the clutch groove is arranged on the nut; a clutch notch is formed in the clutch groove; and the clutch notch and the clutch clamping hook are suitable for forming a connection state and a separation state. The hidden danger of damage to the automatic door opening and closing mechanism when the automatic door opening and closing mechanism is subjected to sudden impact external force in the driving process can be reduced.
本发明涉及一种自动开关门机构及使用其的冰箱，包括：可正反转动力输出的动力源；适于驱动冰箱门体相对于冰箱箱体打开和关闭的伸缩驱动组件；伸缩驱动组件包括与动力源传动连接的螺杆、与螺杆传动连接的螺母，以及与螺母配接的伸缩杆；其中伸缩杆上设有离合槽，螺母上设有适于嵌入在离合槽中的离合卡勾；离合槽内具有离合缺口；且该离合缺口与离合卡勾适于形成连接和脱离状态。本发明可以降低自动开关门机构在驱动过程中受到突发性冲击外力时的损伤隐患。
