[0038] The application will be described in connection with the preferred embodiments.

[0039] Embodiment one

[0040] Please refer to Figure 1 , Figure 1 is a schematic diagram of the whole according to the embodiment of the application. As shown in Figure 1 , a window curtain motor device suitable for Roman poles includes an auxiliary driving mechanism 1 and a main driving mechanism 2.

[0041] Please refer to Figures 2 to 4 , Figure 2 is a schematic diagram of the up and down adjustment of the main driving mechanism and the auxiliary driving mechanism when using a 40mm pole diameter Roman pole according to the embodiment of the application; Figure 3 is a schematic diagram of the up and down adjustment of the main driving mechanism and the auxiliary driving mechanism when using a 15mm pole diameter Roman pole according to the embodiment of the application; Figure 4 is an exploded view of the auxiliary driving mechanism according to the embodiment of the application. As shown in Figures 2 to 4 , a window curtain motor device suitable for Roman poles further includes a constant pressure spring and a guide rod 5.

[0042] One end of the constant force spring 4 is connected with the auxiliary driving mechanism upper shell 21, and the other end of the constant force spring 4 is provided with a buckle hole 14 matched with the first buckle 13. The constant force spring 4 is fixed to the main driving mechanism B shell 12 through the first buckle 13 and a plurality of third screws 83, and a constant force spring cover 16 is covered. Wherein, the constant force spring 4 is a spring capable of maintaining constant elasticity within a corresponding stroke. In the application, the constant force spring 4 functions to ensure that the main driving mechanism 2 and the auxiliary driving mechanism 1 tightly hold the Roman pole 9, thereby ensuring that the main driving mechanism 2 generates constant pressure on the main driving wheel 75 of the Roman pole 9, and further ensuring the friction between the main driving wheel 75 and the Roman pole 9. In detail, the constant force spring in the application has basically constant pressure and basically constant friction under different pole diameters. When adapting to different pole diameters, the constant force spring can avoid the occurrence of slippage due to insufficient pressure when the pole diameter is too small, and the occurrence of excessive wear or even direct lockout when the pole diameter is too large. At the same time, it is also beneficial to pass the gap. For example, two groups of poles are spliced through an adapter to cause a gap, or two poles with different diameters are spliced to cause a gap. When the window curtain motor passes the gap, the change in the distance between the main driving mechanism and the auxiliary driving mechanism is adjusted by the constant force spring. The pressure of the driving wheel remains constant when passing the gap, so as to avoid the situation that the driving wheel is stuck in the position of the gap and cannot pass or slips directly due to the change of pressure after passing the gap.

[0043] The main driving mechanism 2 is connected with the auxiliary driving mechanism 1 through a guide rod 5, one end of the guide rod 5 is fixedly connected to the auxiliary driving mechanism lower shell 22 through a plurality of second screws 82, the other end of the guide rod 5 is fixedly arranged in a guide hole 17 of the main driving mechanism B shell 12, and the other end of the guide rod 5 is provided with a first clamping spring 121.

[0044] The application can adjust the auxiliary driving mechanism 1 up and down by stretching the constant force spring 4, so that the Roman rod 9 of different diameters can be matched.

[0047] The working principle of the auxiliary driving mechanism is as follows: when the Roman rod 9 passes through the gap, the front auxiliary driving wheel 321 is lifted upward, and the rear auxiliary driving wheel 322 is pressed by the force of the elastic element 35, so that the Roman rod 9 is pressed tightly, and the Roman rod 9 passes through the gap stably.
