The second reel 54 is located outside the winding drum 4, and the second reel 54 is located between the left mounting plate 2 and the winding drum 4.

By adopting the structure, under the driving of the motor 50, the motor rotating wheel 52 drives the winding drum 4 to synchronously rotate, the winding drum 4 drives the left end cover 53, the torsion spring rotating wheel 61 and the right end cover 65 to synchronously rotate, the left end cover 53 drives the second winding wheel 54 to synchronously rotate, and the torsion spring rotating wheel 61 drives the second rotating wheel 66 to synchronously rotate.

As shown in fig. 2, 7 and 8, each of the left and

right rail assemblies

91 and 92 includes a side rail body and a guide rail provided in the side rail body. The left and

right zippers

81 and 82 are installed in the guide rails of the left and

right rail assemblies

91 and 92, respectively. The left rail assembly 91 has a left upper pulley 931 and a left lower pulley 941 at upper and lower ends thereof, and the right rail assembly 92 has a right upper pulley 932 and a right lower pulley 942 at upper and lower ends thereof.

When the electric rolling shutter is in operation, the circuit control module controls the tubular motor 50 to rotate after the rolling shutter is electrified, so as to drive the rolling drum 4 to rotate synchronously. When the winding drum 4 rotates synchronously with the tubular motor 50, the left end cover 53 connected with the inner wall of the winding drum 4 drives the second winding wheel 54 to rotate synchronously with the tubular motor 50, and the torsion spring rotating wheel 61 connected with the inner wall of the winding drum 4 also rotates synchronously with the tubular motor 50. The torsion spring wheel 61 rotates the first roller 66 fixed on the transmission shaft 60 through the torsion spring 63. Thus, the reel 4 rotates in synchronization with the first reel 66 and the second reel 54.

When the curtain needs to be horizontally unfolded, the tubular motor 50 drives the winding drum 4, the first winding wheel 66 and the second winding wheel 54 to rotate forwards synchronously. During the rotation, the first winding wheel 66 and the second winding wheel 54 continuously wind and wind the circulating rope 12, and as the circulating rope 12 is wound, the bottom rod 10 at the bottom end of the curtain cloth 7 is pulled to drive the curtain cloth 7 to move towards the horizontal direction far away from the housing 1, and meanwhile, the winding drum 4 continuously releases the curtain cloth 7. In the process, the two ends of the curtain cloth 7 are pulled by the winding drum 4 and the bottom rod 10 all the time, so that the curtain cloth 7 is flat and free of wrinkles in the moving process, and the working stability of the roller shutter is realized.

When the curtain cloth needs to be horizontally folded, the tubular motor 50 drives the winding drum 4, the first winding wheel 66 and the second winding wheel 54 to synchronously rotate reversely. During rotation, the first reel 66 and the second reel 54 continuously release the endless rope 12. As the drum 4 is reversed and the endless rope 12 is released, the bottom bar 10 follows the curtain 7 towards the casing 1 until fully retracted. In the process, the two ends of the curtain cloth 7 are always pulled by the winding drum 4 and the bottom rod 10, so that the curtain cloth 7 is ensured to be flat and wrinkle-free in the moving process, and the working stability of the roller shutter is realized.

Since the thickness of the curtain cloth 7 is smaller than the diameter of the circulating rope 12, during the movement of the curtain cloth 7 and the circulating rope 12, the situation that the diameter of the curtain cloth roll wound on the winding drum 4 is inconsistent with the diameter of the circulating rope roll wound on the first winding wheel 66 and the second winding wheel 54 inevitably exists, the movement stroke of the curtain cloth 7 is inconsistent with that of the circulating rope 12, so that the problem of transport jam can occur, and the curtain cloth 7 or the circulating rope 12 is torn off. The utility model discloses in, through setting up torsional spring subassembly 6, with the help of the elasticity of torsional spring 63 for can form relative rotation displacement between reel 4 and first rolling wheel 66, the second rolling wheel 54, thereby compensate the stroke difference between above-mentioned curtain cloth 7 and the circulation rope 12, overcome the card problem of dying, avoided curtain cloth 7 or circulation rope 12 to be torn.
