The transmission rod 60 is a stainless steel core. The right end of the transmission rod 60 is mounted on the right mounting plate 3 through a bearing. A torsion spring wheel 61 is mounted on the left end of the drive link 60 by a bearing. The torsion spring wheel 61 has a groove on its circumference for engaging with the rib 41 on the inner wall of the drum 4.
The right end part of the transmission rod 60 is provided with a torsion spring fixed wheel 64, a right end cover 65 and a first winding wheel 66 from left to right in sequence. A torsion spring fixed pulley 64 and a first winding pulley 66 are secured to the drive link 60. The right end cap 65 is mounted on the drive link 60 by a bearing. The right end cap 65 has a locking groove on its circumference for engaging with the rib 41 on the inner wall of the winding drum 4.
The two ends of the torsion spring 63 are respectively connected with the torsion spring rotating wheel 61 and the torsion spring fixed wheel 64. A stop collar 62 is fixed to the transmission rod 60 on the inner side of the torsion spring roller 61, and the stop collar 62 can prevent the torsion spring roller 61 from axially moving on the transmission rod 60.
The torsion spring assembly 6 is inserted into the winding drum 4 from the right end of the winding drum 4, and the convex ribs 41 on the inner wall of the winding drum 4 are clamped in the clamping grooves of the torsion spring rotating wheel 61 and the right end cover 65. The first reel 66 is exposed outside the reel 4. The first reel 66 is located between the right mounting plate and the reel drum 4.
As shown in fig. 5 and 6, the motor assembly 5 includes a circuit control module, a tubular motor 50, a motor wheel 52, a left end cap 53, and a second winding wheel 54. The circuit control module is connected with the tubular motor 50 and controls the tubular motor 50 to start, stop, rotate forwards and backwards. The stroke part of the left end of the tubular motor 50 is fixed to the left mounting plate 2.
An output shaft 51 extends from the right end of the tubular motor 50, and a motor wheel 52 is fixed on the output shaft 51. The motor wheel 52 has a slot on its circumference for engaging the rib 41 on the inner wall of the drum 4. The left end cap 53 is rotatably mounted on the left end of the tubular motor 50, and the left end cap 53 is mounted on the tubular motor to be rotatable relative to the tubular motor 50. The left end cap 53 also has a locking groove on its circumference for engaging with the rib 41 on the inner wall of the winding drum 4. The second winding wheel 54 is fixedly connected to the left end cap 53.
The motor assembly 5 is inserted into the winding drum 4 from the left end of the winding drum 4, and the rib 41 on the inner wall of the winding drum 4 is clamped in the clamping groove of the motor rotating wheel 52 and the clamping groove of the left end cover 53. 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. The bottom bar 10 includes a bottom bar body 100, and a left pulley 101 and a right pulley 102 respectively provided at left and right bottom corners of the bottom bar body 100.
A circulating rope 12 is arranged between the first roller 66 and the second roller 54, two ends of the circulating rope 12 are respectively wound and fixed on the first roller 66 and the second roller 54, and the body of the circulating rope 12 sequentially bypasses a right upper pulley 932, a right lower pulley 942, a right pulley 102, a left pulley 101, a left lower pulley 941 and a left upper pulley 931 from right to left.
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 circulating rope 12 is released, the bottom bar 10 follows the curtain 7 towards the casing 1 until it is fully retracted. In the process, the two ends of the cord fabric 7 are also pulled by the winding drum 4 and the bottom rod 10 all the time, so that the cord fabric 7 is ensured to be flat and free of wrinkles in the moving process, and the working stability of the roller shutter is realized.
Since the thickness of the cord fabric 7 is smaller than the diameter of the circulating rope 12, during the movement of the cord fabric 7 and the circulating rope 12, the situation that the diameter of the cord fabric 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, which leads to the situation that the movement stroke of the cord fabric 7 is inconsistent with the movement stroke of the circulating rope 12, so that the problem of transport jam can occur, and the cord fabric 7 or the circulating rope 12 is torn off. In the invention, by arranging the torsion spring assembly 6, the relative rotational displacement between the winding drum 4 and the first winding wheel 66 and the second winding wheel 54 can be formed by means of the elasticity of the torsion spring 63, so that the stroke difference between the curtain cloth 7 and the circulating rope 12 is compensated, the problem of blocking is overcome, and the curtain cloth 7 or the circulating rope 12 is prevented from being torn off.
