The second buckle assembly 141 is different from the first buckle assembly 140 in that the first buckle 15 is also provided with a through hole 19, but the through hole 19 is for the first belt 6 to pass through, and the second belt 7 passes through the clamping cavity 18, and the clamping cavity 18 clamps the second belt 7. Therefore, the specific structure of the corresponding first buckle 15 is different. Fig.10 , 11 shown.

[0047] like Figure 3 As shown, two first transmission boxes 8 are also included. The first transmission boxes 8 are used to transmit the first transmission member and the first output end of the first double-headed motor; the two first transmission boxes 8 are arranged at the two first output ends of the first double-headed motor.

[0050] The first transmission box 8 and the second transmission box 9 both include a first pulley 10 and a second pulley 11. The first pulley 10 is sleeved on the first output end of the first double-headed motor and the output end of the second double-headed motor located on the same side, and the second pulley 11 is rotatably connected to the first pulley 10.

[0051] In the first transmission box 8, the side of the first pulley 10 is connected to the first belt 6, and the side of the second pulley 11 is connected to the second belt 7; in the second transmission box 9, the side of the first pulley 10 is connected to the second belt 7, and the side of the second pulley 11 is connected to the first belt 6.

[0052] like Figure 7 , 8 As shown, the first output shaft of the first double-headed motor and the second output shaft of the second double-headed motor are both sleeved with a first pulley 10, and the first pulley 10 is coaxially fixedly connected to the first output end of the first double-headed motor and the output end of the second double-headed motor, and rotates simultaneously with the first output end of the first double-headed motor and the second output end of the second double-headed motor, while the second pulley 11 is rotationally connected to the first pulley 10, and preferably, the side surface of the first pulley 10 can be formed with a tooth surface, and the corresponding first pulley 10 forms a tooth surface to ensure that the contact between the first pulley 10 and the first belt 6 is not smooth to achieve transmission. The first pulley 10 is provided with a stepped groove for the second pulley 11 to be sleeved, and the second pulley 11 is conveniently sleeved on the first pulley 10 through the action of the stepped groove, and the second pulley 11 does not rotate with the first output end of the first double-headed motor and the second output end of the second double-headed motor. Thereby, the subsequent transmission is guaranteed. Since the first driving source 4 is arranged at the upper end of the curtain frame 1, and the second driving source 5 is arranged at the lower end of the curtain frame 1, the first pulley 10 at the upper end corresponds to the second pulley 11 at the lower end, and the two are connected by the first belt 6, while the second pulley 11 at the upper end corresponds to the first pulley 10 at the lower end, and the two are connected by the second belt 7.

[0053] That is, in the first transmission box 8, the first output shaft of the first double-headed motor drives the first pulley 10 to rotate, while the second pulley 11 does not rotate, the corresponding first belt 6 moves, and the second belt 7 does not move, so that the first curtain traction member 2 moves, and the second curtain traction member 3 does not move, so as to realize the opening and closing of the day curtain. In the second transmission box 9, the second output shaft of the second double-headed motor drives the first pulley 10 to rotate, while the second pulley 11 does not rotate, the corresponding second belt 7 moves, and the first belt 6 does not move, so that the second curtain traction member 3 moves, and the first curtain traction member 2 does not move, so as to realize the opening and closing of the night curtain.

[0054] The first transmission box 8 and the second transmission box 9 both include a first bearing 12 and a second bearing 13 , and the first pulley 10 is connected between the first bearing 12 and the second bearing 13 .

[0055] By providing the first bearing 12 and the second bearing 13, the rotation accuracy of the shaft is ensured, energy consumption is reduced, and Fig.14 , 15As shown, the first bearing 12 and the second bearing 13 are arranged at both ends of the first pulley 10 .
