[0041] The working principle and use process of the utility model are as follows: when using the device, first start the motor 311 to drive the second gear 312 to rotate, and the second gear 312 will drive the inner gear ring 35 to rotate through the outer gear ring 313, and at the same time the inner gear ring 35 will drive the first planetary gear 32, the second planetary gear 33 and the third planetary gear 34 to rotate and move on the outside of the sun gear 31, at the same time the first planetary gear 32, the second planetary gear 33 and the third planetary gear 34 will drive the planetary carrier 37 to rotate through the cylindrical block 36, and the planetary carrier 37 will drive the connecting block 38 and the first gear 24 to rotate together, and at the same time the first gear 24 will drive the first sliding door 21 and the second sliding door 22 to open and close through the first rack 26 and the second rack 27, thereby realizing the effect of electrically controlling the opening and closing of the door.
[0042] When the motor 311 is damaged or the power is cut off, people can directly rotate the rotating rod 42, and the rotating rod 42 will drive the sun gear 31 to rotate. At the same time, the sun gear 31 will drive the first planetary gear 32, the second planetary gear 33 and the third planetary gear 34 to move inside the inner ring gear 35, and the inner ring gear 35 will be restricted by the output shaft of the motor 311 and cannot rotate. Then the first planetary gear 32, the second planetary gear 33 and the third planetary gear 34 will drive the planetary gear 37 to move through the cylindrical block 36, and the planetary gear 37 will drive the connecting block 38 and the first gear 24 to rotate smoothly, thereby driving the first sliding door 21 and the second sliding door 22 to slide and open. Even if the motor 311 is damaged or the power is cut off, the first sliding door 21 and the second sliding door 22 can be opened smoothly, so that people will not be trapped in the house and can leave in time to get rescued. This can solve the problem that when the motor 311 is damaged or the power is cut off, the motor 311 cannot drive the sliding door to open smoothly, thereby causing people to be trapped in the house and unable to leave the room in time.
