When the electric curtain is running, the motor drives the driving pulley to rotate forward and reverse, which can drive the two pulley assemblies on the transmission belt to move away from or close to each other, thereby realizing the automatic opening or closing of the curtain.

[0004] With regard to the above-mentioned related technologies, the driving pulley in the active box of the electric curtain is currently mainly driven by a direct motor.

[0005] In order to improve the output torque of the driving pulley of the electric curtain driving box, the present application provides an electric curtain driving module.

[0006] The electric curtain drive module provided in this application adopts the following technical solution:

[0007] An electric curtain driving module comprises an active box and a power box, wherein the power box is located at the bottom of the active box;

[0008] A driving pulley is rotatably connected in the driving box;

[0010] The power box is connected to the active box via a connecting assembly.

[0011] By adopting the above technical solution, when the driving motor drives the output end of the gear reduction box to rotate, the output end of the gear reduction box drives the driving pulley to rotate through the transmission component. Compared with the traditional method of directly driving the driving pulley through the motor, the gear reduction box can reduce the speed of the driving pulley and increase the torque of the driving pulley, thereby facilitating the driving pulley to drive the transmission belt of the electric curtain more smoothly and powerfully; at the same time, the vibration and noise generated when the driving pulley rotates are reduced. The power box and the active box are connected by the connecting component to achieve a detachable connection between the power box and the active box, so that the power box and the active box do not need to be integrally formed. When the internal parts of the power box and the active box are damaged, the power box and the active box can be removed separately to repair or replace the damaged parts, reducing the overall maintenance cost.

[0012] Preferably, the transmission assembly includes a first transmission block and a second transmission block; the first transmission block is coaxially connected to the bottom side of the driving pulley, and the second transmission block is coaxially connected to the output end of the gear reduction box; the first transmission block and the second transmission block are arranged opposite to each other, and a clamping portion and a clamping groove are respectively provided on opposite sides of the first transmission block and the second transmission block, and the clamping portion is inserted into the clamping groove and clamped with the clamping groove.

When the subsequent driving motor drives the output end of the gear reduction box to rotate, the output end of the gear reduction box can drive the driving pulley in the active box to rotate through the cooperation between the first transmission block and the second transmission block. On the other hand, the first transmission block and the second transmission block are detachable and matched, which facilitates the subsequent disassembly and assembly of the power box to the active box.

When the power box needs to be removed from the active box later, the limiting block is pressed in the direction close to the limiting slot to disengage the limiting protrusion from the plug-in slot, so that the power box can be separated from the active box.

[0028] Preferably, a control circuit board is installed in the power box; a plurality of sensing blocks are evenly protruded around the outer circumference of the second transmission block, and a photoelectric sensor is also provided in the power box, and the photoelectric sensor is located above the moving path of the plurality of sensing blocks; the photoelectric sensor is electrically connected to the control circuit board, and the photoelectric sensor is used to identify the sensing blocks and feed back electrical signals to the control circuit board.
