Through the drive of the door closing drive mechanism, the first door panel 5 and the second door panel 3 can synchronously complete the closing action.

[0022] The door closing drive mechanism includes a drive housing 12, on which a first servo motor is fixedly installed. A first gear 13 is fixedly installed on the output shaft of the first servo motor. The first gear 13 is meshed with a second gear 14 and a third gear 15. The inner wall of the second gear 14 is fixedly connected with a first rotating shaft, and a first winding wheel 141 is installed on the first rotating shaft. A first steel wire rope 7 is wound around the first winding wheel 141. The inner wall of the third gear 15 is fixedly connected with a second rotating shaft, and a second winding wheel 151 is fixedly installed on the second rotating shaft. A second steel wire rope 8 is wound around the second winding wheel 151. The first rotating shaft and the second rotating shaft are both rotationally connected to the drive housing 12 through bearings. The ends of the first steel wire rope 7 and the second steel wire rope 8 are respectively connected between the first door panel 5 and the second door panel 3. The first steel wire rope 7 and the second steel wire rope 8 are respectively drivingly connected with a first guide pulley 17 and a second guide pulley 16. The first guide pulley 17 and the second guide pulley 16 are mainly used to change the direction of the first steel wire rope 7 and the second steel wire rope 8. When the first servo motor drives the first gear 13 to rotate, it jointly drives the second gear 14 and the third gear 15 to rotate, thereby jointly winding the first steel wire rope 7 and the second steel wire rope 8.

[0023] Hanging rings are respectively installed at the upper and lower ends of the first door panel 5 and the second door panel 3. The ends of the first steel wire rope 7 and the second steel wire rope 8 are respectively connected with the hanging rings on the first door panel 5 and the second door panel 3.

The end of the left third steel wire rope 18 is fixedly connected to a hanging ring on the first door panel 5, and the end of the right third steel wire rope 18 is fixedly connected to a hanging ring on the second door panel 3. The four second servo motors are respectively installed on the first support plate 6, the second support plate 11, the third support plate 9, and the fourth support plate 10. The first door closing drive mechanism and the third door closing drive mechanism jointly drive the first door panel 5 to open, and the second door closing drive mechanism and the fourth door closing drive mechanism jointly drive the second door panel 3 to open.

[0027] During specific use, when it is necessary to close the door, when the first servo motor is started to drive the first gear 13 to rotate, the second gear 14 and the third gear 15 are jointly driven to rotate, so as to jointly wind the first steel wire rope 7 and the second steel wire rope 8, so that the second door panel 3 and the first door panel 5 move synchronously and approach each other to close the door. When it is necessary to open the door, the second servo motors in the first door closing drive mechanism and the third door closing drive mechanism work to drive the left third winding wheel 61 to rotate to wind the third steel wire rope 18, so as to drive the second door panel 3 and the first door panel 5 to move away from each other synchronously, thereby realizing door opening.
