[0037] The application will be described in detail below with reference to specific embodiments.

[0038] Embodiment one

[0039] Please refer to Figure 1 , Figure 1 is a whole schematic diagram according to the embodiment of the application. As shown in the figure, Figure 1As shown in the drawings, a floating over the ridge mechanism and a curtain motor device with the same include a main drive mechanism 2 and an auxiliary drive mechanism 1.

As Figures 2 to 4 As shown in the drawings, a floating over the ridge mechanism and a curtain motor device with the same include a main drive mechanism 2 and an auxiliary drive mechanism 1.

[0041] 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 buckle 13, the constant force spring 4 is fixed to the main driving mechanism B shell 12 through the buckle 13 and a plurality of third screws 83, and the 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, and the role of the constant force spring 4 in the application is to ensure that the main driving mechanism 2 and the auxiliary driving mechanism 1 tightly hold the Roman rod 9, so as to ensure that the Roman rod 9 generates constant pressure on the rubber wheel 75 of the main driving mechanism 2, and then ensure the friction between the rubber wheel 75 and the Roman rod 9, in detail, the constant force spring in the application has basically constant pressure and friction under the same rod diameter, which avoids the occurrence of slippage due to insufficient pressure when the rod diameter is too small, and the occurrence of excessive wear or even direct locking and driving failure due to excessive pressure when the rod diameter is too large. At the same time, it is also beneficial to pass the gap, for example, two groups of rods are spliced by the adapter to cause the existence of the gap, or one thick and one thin rod is spliced to cause the existence of the gap, by arranging the constant force spring, when the curtain motor passes the gap, the change of the distance between the main driving mechanism and the auxiliary driving mechanism (i.e. the floating gap passing mechanism) is adjusted by the constant force spring, the pressure of the driving wheel is consistent and constant when passing the gap, so that the driving wheel is not stuck in the position of the gap and cannot pass or directly slips due to the change of pressure after passing the gap, at the same time, by arranging the floating adjusting mechanism, the position of the auxiliary driving wheel (i.e. at least two groups of roller assemblies of the floating gap passing mechanism) can be directly and individually adjusted, without the need for transmission to the constant force spring through the shell and adjustment through the constant force spring, the adjustment is more agile and rapid, and more delicate, reducing the adjustment of the constant force spring when the shell passes the gap, improving the stability of the shell passing the gap, and the whole gap passing process is more delicate and smooth.

[0042] The main driving mechanism 2 and the auxiliary driving mechanism 1 are connected through the 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 the guide hole 17 of the main driving mechanism B shell 12, and the other end of the guide rod 5 is provided with a second spring.

[0043] The application can adjust the auxiliary driving mechanism 1 up and down by stretching the constant force spring 4 without disassembling the original hanging rod, and by holding the main driving mechanism 2 and the auxiliary driving mechanism 1 with both hands.

[0044] Please refer to Figures 5 to 6 , Figure 5 It is an auxiliary driving mechanism explosion diagram of the application; Figure 6 It is an auxiliary driving mechanism roller schematic diagram of the application.

At the same time, the V-shaped structure further enhances the hanging stability of the floating threshold mechanism. For example, when hung on a curtain track, it prevents the position of the curtain motor on the Roman rod from shifting due to wind or curtain swaying, requiring the user to reinstall and adjust.

[0045] The installation operation of the auxiliary drive mechanism is as follows: the floating block 34 is connected to the rotating shaft 33. After the roller 32 is installed in the positioning groove, the buckle 31 is placed and the roller 32 is fixed to the lower shell 22 of the auxiliary drive mechanism by multiple first screws 81 according to the screw holes on the buckle 31.

[0046] The working principle of the auxiliary drive mechanism is as follows: When the Roman rod 9 crosses the bump, the front roller 321 is lifted upwards. Due to the force of the compression spring 35, the rear roller 322 is pressed down, and the rear roller 322 presses the Roman rod 9 so that the Roman rod 9 can cross the bump smoothly.
