[0002] Rolling shutter doors, also known as "rolling doors", are made up of many jointed door panels connected in series. In a fixed slide, the doors rotate up and down around the scroll above the door. There are two types of rolling shutter doors: manual and electric.

[0003] Manual mode: With the help of the torsion spring on the central axis of the roller shutter to balance the force, the roller shutter can be easily opened and closed manually.

[0043] The reel assembly 100 is subjected to the external force applied by the driving unit 300, and the reel assembly 100 drives the side panel 2 to move on the balance end 11, and the guide rail 4 cooperates with the side panel 2 to move on the side panel frame 1, so that the door panel hanging point P1 in the reel assembly 100 is vertical to the door panel groove installation point P2.

[0044] Specifically, the side panel 2 is provided with a speed reduction mechanism 5 cooperating with the balancing end 11, and the reel assembly 100 is provided with an intermittent dialing portion 33 cooperating with the speed reduction mechanism 5. When the reel assembly 100 rotates counterclockwise or clockwise, the intermittent dialing portion 33 located on the side of the reel assembly 100 intermittently controls the relative movement of the speed reduction mechanism 5 and the balancing end 11, so that the reel assembly 100 moves horizontally on the side panel frame 1 along with the side panel 2. According to the state of the reel assembly 100 being wound or released, the position of the door panel drooping point P1 and the door panel groove installation point P2 are controlled relative to each other.

[0045] Specifically, the reel assembly 100 includes a shaft rod 6 and a follower mechanism 3, wherein the follower mechanism 3 is located at both ends of the shaft rod 6 and is connected to the side plate 2, and the follower mechanism 3 includes a central shaft 32 and a fastener 35 sleeved on the central shaft 32, one end of the central shaft 32 is fixed on the side plate 2, and the other end is provided with a bearing 34 for fixed rotation of the fastener 35, wherein the intermittent toggle portion 33 is connected to the side end of the fastener 35, and the other side of the fastener 35 is connected to the shaft rod 6.

The connecting portion 332 extends through the fastener 35 so that the convex head 331 is evenly arranged on one side of the fastener 35. The intermittent toggle portion 33 and the fastener 35 are integrally linked. The fixed axis is driven to rotate by the driving unit 300 and is linked to the speed reduction mechanism 5 through the convex head 331. In this structure, the toggle rod is fitted on the flange 38.

[0047] In this structure, in order to ensure the stability of the structure, a pad 36 and a bolt 333 are provided to fit between the intermittent toggle portion 33 and the fastener 35 .

The shell 53 has a cavity inside that is adapted to the trigger member 51 and the speed change gear 52. Since the trigger member 51 and the speed change gear 52 rotate on a fixed axis, there is also a fixed axis member to match the trigger member 51 and the speed change gear 52 for fixing;

[0052] In order to better ensure the compactness of the structure, the positioning housing 53 is further provided with a curved surface 531 so that the spacer node portion 511 is effectively ensured within the structure to prevent dust;

[0058] In some cases, a concave surface is provided on the polygonal gear to effectively match the protrusion 331, because the protrusion 331 is not limited to a cylindrical shape, and can also be other shapes that can achieve the corresponding effect.

[0059] Specifically, the side plate assembly 200 is divided into an organic end S1 and an inorganic end S2. The driving unit 300 is located on the organic end S1, and the follower mechanism 3 is provided with a traction part 31 adapted to the driving unit 300.

[0065] Principle: The reel assembly 100 is subjected to the external force applied by the driving unit 300, and the reel assembly 100 drives the side panel 2 to move on the balancing end 11, and the guide rail 4 cooperates with the side panel 2 to move on the side panel frame 1, so that the door panel drooping point P1 in the reel assembly 100 is perpendicular to the door panel slot installation point P2. Because when the reel assembly is reeling or releasing the door panel, the position of the door panel drooping point P1 in the reel assembly must always be kept perpendicular to the door panel slot installation point P2 to ensure that the door panel is not damaged or produces abnormal noise under the influence of the door panel slot. Therefore, the position of the side panel must change with the thickness of the combination of the reel assembly and the door panel. The driving unit 300 controls the rotation of the reel assembly 100, and the speed reduction mechanism links the side panel to move horizontally on the side panel frame to control the effective distance of the door panel drooping point P1. The intermittent touch control method combined with the speed reduction mechanism can better control the coordination of the reel assembly 100 with the rack during reeling and releasing.
