[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 4As shown, a curtain driving device comprises a driver housing 1, an assembly portion 11 is provided on the outer side of the driver housing 1; a first driving member 291 and a second driving member 292, an opening and closing transmission member 21 connected to the first driving member 291 for transmission and docking, and a dimming transmission member 22 connected to the second driving member 292 for transmission and docking are provided in the driver housing 1, a first transmission docking port 111 for exposing the opening and closing transmission member 21, and a second transmission docking port 112 for exposing the dimming transmission member 22 are provided on the assembly portion 11, and a docking structure is further provided on the assembly portion 11, and the docking structure is used to enable the driver housing 1 to be clamped on the transmission box of the curtain guide rail. The driver housing 1 is provided with an assembly portion 11 so that after the driving device is docked with the dream curtain transmission box, the first driving member 291 and the second driving member 292 can respectively drive the curtain to move. In this solution, the driver housing 1 can be docked with the curtain transmission box through the docking structure on the assembly portion 11, and the opening and closing transmission member 21 and the dimming transmission member 22 can be kept in the corresponding position of the transmission box for transmission. The overall structure is simpler, and the installation and disassembly operations are convenient, and the connection is more stable.

[0029] In this solution, the first driving member 291 and the second driving member 292 can both be motors, and when they are in motion, they will generate vibrations, which are transmitted back to the driver housing 1. In order to strengthen the connection stability between the driver housing 1 and the transmission box or the curtain rail, the driver housing 1 is provided with a first assembly position 101 on the outside, and the assembly portion 11 is located on one side of the first assembly position 101. The first assembly position 101 is assembled with the structure corresponding to the transmission box or the curtain rail to achieve a more stable connection effect, such as through a concave and convex assembly structure, or a card slot structure can be used.

[0030] Specifically, in this solution, the first assembly position 101 is a recessed position that is recessed inward from the side of the driver housing 1, and the recessed position at least penetrates to the upper end surface of the driver housing 1 to form a docking port 103. Correspondingly, a corresponding protrusion is provided on the outer wall of the transmission box or the curtain guide rail, so that during assembly, the first assembly position 101 is vertically slid from the docking port to complete the alignment, and this structure can reduce the vibration of the driver housing relative to the curtain when working, thereby maintaining the effectiveness of the connection.

[0031] Of course, the assembly portion 11 can also adopt the principle of assembly position, such as through a concave and a convex assembly structure. In the embodiment of the utility model, the assembly portion 11 is a connection seat protruding outward from the outside of the driver housing 1, and the upper end of the connection seat forms an assembly port 102 located on one side of the docking port 103. It mainly considers that two sets of driving parts need to be installed inside the driver housing 1, so its convex connection seat increases the available space inside. In this solution, the first driving member 291 and the second driving member 292 are installed in a mutually perpendicular posture, so that the installation is more compact and the overall size of the driving device is greatly reduced. In addition, the assembly port 102 is arranged to facilitate the driver housing 1 to be guided by the assembly port 102 at the upper end during installation, forming an effect of sliding installation up and down, making the installation simpler.

[0032] Specifically, in this solution, the connection seat includes a first protrusion 118 and a second protrusion 119, and the first protrusion 118 and the second protrusion 119 form a stepped connection seat. The stepped connection seat is conducive to positioning after installation. In the embodiment of the utility model, the first transmission docking interface 111 is arranged on the first protrusion 118, and the first transmission docking interface 111 is arranged on the second protrusion 119. Moreover, the first transmission docking interface 111 starts horizontally and the second transmission interface 112 is opened vertically. In this way, through the stepped connection seat, after being installed at the corresponding position of the transmission box, the stepped plane forms an assembly with the corresponding position of the transmission box, and the first protrusion 118 and the second protrusion 119 are positioned at the same time, so that the first transmission docking interface 111 on the first protrusion 118 and the second transmission interface 112 on the second protrusion 119 can be better positioned, so that the transmission docking of the opening and closing transmission member 21 and the dimming transmission member 22 is more stable.

[0033] In the embodiment of the utility model, the entire installation process is made simpler by a docking structure, specifically, the docking structure includes a guide portion 1101 and a locking portion 1102, and the guide portion 1101 is located on both sides of the assembly portion 11. Similarly, at the installation position corresponding to the transmission box, there is also a structure that cooperates with the guide portion 1101 and the locking portion 1102, so that combined with the above-mentioned sliding installation effect, it can be locked by the locking portion 1102 after sliding into place.

[0034] Specifically, in the embodiment of the utility model, the guide portion 1101 includes a first guide portion 11011 and a second guide portion 11012, wherein the first guide portion 11011 extends along the second protrusion 119 and the first protrusion 118 to the assembly port 102, and the second guide portion 11012 is arranged on the side of the second protrusion 119 and extends to the upper end surface of the second protrusion 119. In this solution, the first guide portion 11011 and the second guide portion 11012 are both provided with installation grooves provided along the vertical direction, so that the corresponding position of the transmission box only needs to be provided with a corresponding snap-in structure to form a guiding sliding installation and a horizontal limiting effect. In this solution, the first guide portion 11011 and the second guide portion 11012 can adopt a structure with an installation groove formed by an L-shaped column, or can adopt an arc-shaped or hook-shaped cross-sectional shape.

[0035] In the embodiment of the utility model, the locking portion 1102 is a bayonet provided on the surface of the second protrusion 119. Correspondingly, the transmission box is provided with a corresponding bayonet protrusion that can be inserted into the bayonet, so that during the sliding installation process, it only needs to slide into place, and the bayonet protrusion can be inserted into the bayonet for locking. Its structure is simple, making installation simpler and more convenient.

[0036] In addition, in the embodiment of the utility model, the driving device also includes a power circuit board arranged in the driver housing 1, and the assembly portion 11 is also provided with a plug interface 114, and the power circuit board is provided with a connection end 211 extending from the plug interface 114, and the power circuit board is used to supply power to the connection end 211. Of course, the power circuit board can also integrate the power supply to the first driving member 291 and the second driving member 292 at the same time. The connection end 211 can be a plug interface or a plug located on the plug interface 114, which is used to connect with the electrical components on the curtain rail through this position after docking with the curtain rail, and supply power to it. For example, on a curtain rail with a light strip, the power circuit board can supply power and control the light strip through the connection end 211 in the plug interface 114, so as to form an atmosphere light effect on the curtain rail.

[0037] In this solution, the plug port 114 is adjacent to the first transmission docking port 111, and the connection end 211 is located on one side of the opening and closing transmission member 21. This makes the connection structure layout more compact, and the connection position is more concentrated after installation, and the connection is more stable.

[0038] In addition, in order to make the connection more stable after insertion, the insertion port 114 is a mounting portion protruding from the upper end of the first protruding portion 118, and a notch is provided in the mounting portion, and the connecting end 211 is exposed from the notch. The overall protruding shape of the mounting portion can be provided with a corresponding notch at the corresponding interface of the transmission box, so that the connection is more stable after installation.

[0039] In this solution, the upper end surface of the first protrusion 118 is lower than the upper end surface of the driver housing 1. It can make the driver housing 1 and the transmission box integrated after installation, and as in the above-mentioned recorded solution, the assembly part 11 is a part protruding from the driver housing, and correspondingly, a part of the transmission box is recessed for the assembly part to be embedded and installed, and after installation, only the driver housing 1 is exposed on one side of the curtain, and the upper end surface of the first protrusion 118 is lower than the upper end surface of the driver housing 1, which is equivalent to forming a positioning step. After assembly, the upper end surface of the first protrusion 118 abuts against the inside of the transmission box, and at the same time, the upper end surface of the driver housing 1 can be flush with the upper end surface of the transmission box.

[0040] like Figure 5 and Figure 6 As shown, the utility model further provides a dream curtain, including a curtain rail 91, and transmission boxes are provided on both sides of the curtain rail 91, and the transmission box on one side is connected to the above-mentioned curtain driving device.

[0041] The utility model provides a curtain driving device, wherein the driving device is connected to the dream curtain transmission box through an assembly part on the driving housing, so that the first driving member and the second driving member can respectively drive the curtain to move. In this scheme, the driving housing and the curtain transmission box can be connected through the docking structure on the assembly part, and the opening and closing transmission member and the dimming transmission member can be kept in the corresponding position of the transmission box for transmission. The overall structure is simpler, and the installation and disassembly operations are convenient, and the connection is more stable.
