Description

Technical Field

[0001] The utility model relates to the technical application field of rolling shutter doors, in particular to a rolling shutter door movement balancing system with a built-in drive. Background Art

[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.

[0004] Electric mode: A special motor is used to drive the central axis of the rolling curtain to rotate, reaching the rolling curtain switch, and it will automatically stop when it reaches the upper and lower limits set by the motor;

[0005] With the improvement of people's living standards and the demand for convenience, electric rolling shutters are being used more and more. The electric rolling shutters of existing products mainly include: motor, sprocket, door curtain drum, door panel, the sprocket is fixedly connected to the door curtain drum, when the door is opened or closed by a button or remote control device, the motor rotates, and the motor output shaft drives the sprocket to rotate synchronously through the chain, and the sprocket drives the door curtain drum to rotate synchronously to roll up or down the door panel.

[0006] A rolling shutter door control device proposed in the existing announcement number (CN215169635U) is innovated on this basis. Since the span of the gear lever is relatively large, it is difficult to adjust the position of the side plate movement in the side plate frame movement, so that the position of the rolling shutter shaft cannot move quickly and uniformly, which will cause abnormal movement of the rolling shutter shaft and is not conducive to the application of the rolling shutter door mechanism. For this purpose, a built-in driven rolling shutter door moving balance system is proposed. Utility Model Content

[0041] Among them, the driving unit 6 is built into the reel 4 and is connected to the follower mechanism 5 on a single side, so that the reel assembly 200 rotates on a fixed axis on the side panel 2, and the follower mechanism 5 drives the speed change mechanism 3 to move on the balancing part 11, controlling the side panel 2 to slide on the side panel frame 1, and the reel assembly 200 moves with the side panel 2, so that the door panel winding point P1 on the reel assembly 200 is vertically on the door guide groove point P2.

[0042] Specifically, the follower mechanism 5 is provided with a lever 7 adapted to the speed change mechanism 3, and the speed change mechanism 3 is composed of a trigger member 31 and a speed change member 32, wherein the trigger member 31 is subjected to the external force applied by the lever 7, driving the speed change member 32 to rotate, causing the speed change member 32 to move on the balancing part 11. In this structure, the reel assembly 200 rotates counterclockwise, and the side plate 2 moves to the left on the side plate frame 1.

[0043] Specifically, the speed change member 32 is respectively engaged with the trigger member 31 and the balancing part 11 for transmission connection.
