Description

Technical Field

[0001] This utility model relates to the field of Venetian blind technology, specifically to a Venetian blind drive device and system. Background Technology

[0002] In recent years, with the rapid development of smart home technology, motorized Venetian blind systems have gradually become mainstream products in the architectural shading field due to their convenient operation. Currently, most commercially available motorized Venetian blind systems integrate the blind motor and transmission mechanism within the blind track. The motor is connected to the blind slats via the transmission mechanism to control the opening and closing of the slats. While this design ensures a certain degree of structural compactness and achieves concealed installation of the motorized Venetian blind system, this type of integrated design has the following significant drawbacks:

[0003] 1. Difficult and inconvenient maintenance, repair, and cleaning. Since the Venetian blind motor and transmission mechanism are built into the blind track, when a malfunction occurs and repair or maintenance is needed, the entire motorized Venetian blind system must be disassembled to repair or replace the motor and transmission mechanism. Similarly, cleaning the track requires disassembly of the entire motorized Venetian blind system. However, this disassembly often requires specialized tools, making disassembly and assembly difficult and maintenance and repair very inconvenient.

[0004] 2. The large size of the Venetian blind track structure limits the application of motorized Venetian blind systems in confined spaces. Because the Venetian blind motor and transmission mechanism are built into the Venetian blind track, the cross-sectional dimensions of the track, i.e., the width of the track, are forced to be larger than those of traditional manual Venetian blind tracks to accommodate the motor and transmission mechanism. This expansion in size severely limits the applicability of motorized Venetian blind systems in narrow spaces. Utility Model Content

[0026] Please refer to Figure 1 , Figure 1 This is a perspective view of a Venetian blind drive device. This embodiment provides a Venetian blind drive device, which includes a drive motor 1, a transmission mechanism 2, and a track system 3. The drive motor has a drive end. The track system 3 includes a curtain track 31 and a transmission rod 32. The drive motor 1 is located outside the curtain track 31, so that the drive motor 1 and the curtain track 31 are arranged side-by-side. The curtain track 31 and the drive motor 1 are located side-by-side on the same side of the transmission mechanism 2, and the drive end of the drive motor 1 is drive-connected to the transmission mechanism 2. The curtain track 31 is detachably connected to the transmission mechanism 2. Preferably, one end of the curtain track 31 is engaged with the transmission mechanism 2, so that the curtain track 31 is detachably connected to the transmission mechanism 2 while maintaining stability relative to the transmission mechanism 2. The transmission rod 32 is located inside the curtain track 31 and is drive-connected to the transmission mechanism 2.

[0027] In use, the drive motor 1 and the transmission rod 32 are respectively connected to the transmission mechanism 2. The drive motor 1 provides driving force. When the drive motor 1 is working, it drives the transmission mechanism 2 to work. At the same time, the transmission mechanism 2 drives the transmission rod 32 to rotate. Thus, the drive motor 1 drives the transmission rod 32 to rotate after being transmitted through the transmission mechanism 2.

[0028] In this embodiment, the Venetian blind drive device, by placing the drive motor 1 on one side of the curtain track 31, arranges the drive motor 1 and the curtain track 31 side by side in the vertical direction, effectively reducing the overall length of the Venetian blind drive device and making it adaptable to more different usage scenarios. Furthermore, by placing the drive motor 1 outside the curtain track 31, it facilitates the maintenance and disassembly of the drive motor 1.

[0029] Please refer to Figure 2 and Figure 3 , Figure 2 This is an exploded view of the transmission mechanism. Figure 3This is a schematic diagram illustrating the transmission assembly. Further, the transmission mechanism 2 includes a housing 21 and a transmission assembly 22. The transmission assembly 22 is housed within the housing, with the drive motor 1 and the curtain rail 31 located side-by-side on the same side of the housing 21. The drive end of the drive motor extends into the housing for transmission connection with one end of the transmission assembly 22. The curtain rail 31 is detachably connected to the housing 21. One end of the transmission rod 32 extends into the housing, and this end is connected to the other end of the transmission assembly 22. When the drive motor 1 operates, it drives the transmission assembly 22 to rotate, which in turn drives the transmission rod 32 to rotate.

[0030] Specifically, the housing 21 includes a body 211 and a cover 212. The body 211 includes a receiving portion 2111 and a connecting portion 2112. The receiving portion 2111 is hollow inside, and the cover 212 covers the bottom of the receiving portion 2111, forming a receiving space between the cover 212 and the receiving portion 2111. The receiving space is formed by the cover 212 and the body 211, and the transmission component 22 is located within the receiving space. In this way, the transmission component 22 is placed in the receiving space to protect it and prevent foreign objects from obstructing its operation during the operation of the blind drive device. The connecting portion 2112 protrudes from the surface of the receiving portion 2111. The connecting portion 2112 is embedded in one end of the curtain track 31, so that the curtain track 31 is securely connected to the housing 21. The transmission rod 32 is located inside the curtain rail 31, and one end of the transmission rod 32 passes through the connecting part 2112 and the receiving part 2111 in sequence, and is connected to one end of the transmission component 22 located in the receiving space. The driving end of the drive motor 1 passes through the receiving part 2111 and is connected to the other end of the transmission component 22.

[0031] Further, please refer to Figure 2 The transmission assembly 22 includes a first transmission wheel 221, a second transmission wheel 222, and a third transmission wheel 223. These three transmission wheels are arranged within the housing 21. The shaft of the first transmission wheel 221 is connected to the drive end of the drive motor 1. The second transmission wheel 222 is located to one side of the first transmission wheel 221, and the first and second transmission wheels 221 mesh with each other. The third transmission wheel 223 is located on the side of the second transmission wheel 222 away from the first transmission wheel 221. The third transmission wheel 223 meshes with the second transmission wheel 222, and its shaft is connected to the transmission rod 32.

[0032] In actual use, the drive end of the drive motor 1 drives the first transmission wheel 221 to rotate, which in turn drives the second transmission wheel 222 to rotate. Simultaneously, the second transmission wheel 222 drives the third transmission wheel 223 to rotate. When the third transmission wheel 223 rotates, it drives the transmission rod 32 to rotate coaxially. Thus, through the mutual cooperation of the first transmission wheel 221, the second transmission wheel 222, and the third transmission wheel 223, the transmission between the drive motor 1 and the transmission rod 32 is completed.

[0033] In addition, the drive motor 1 has a built-in intelligent control module, which enables the drive motor 1 to have wireless remote control, mobile APP control and offline voice control functions.

[0034] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the stabilizing connector. The Venetian blind drive device also includes a stabilizing connector 4, which includes a snap-fit ​​part 41 and a fastening part 42. The snap-fit ​​part 41 is bent to form a snap-fit ​​position 410, and the snap-fit ​​position 410 is adapted to the outer contour of the motor. The fastening part 42 is connected to the snap-fit ​​part 41, and the fastening part 42 is bent outwards from the snap-fit ​​position 410 and formed on one side of the snap-fit ​​part 41. During connection, the drive motor 1 is snapped into the snap-fit ​​position 410, and the fastening part 42 is fastened to the curtain track 31, so that the drive motor 1 and the curtain track 31 are securely connected.

[0035] Preferably, the snap-fit ​​portion 41 and the fastening portion 42 are integrally formed.

[0036] Please refer to Figure 4 and Figure 5 , Figure 5 This is another perspective view of the Venetian blind drive device. Furthermore, the drive motor 1 has a snap-fit ​​groove 11 on its side wall, and the end of the snap-fit ​​portion 41 has a snap-fit ​​end 411. When the drive motor 1 is in the snap-fit ​​position 410, the snap-fit ​​end 411 is engaged in the snap-fit ​​groove 11, thus securing the drive motor 1 to the stable connector 4 and preventing the drive motor 1 from falling off.

[0037] This embodiment also provides an electric Venetian blind system, including the Venetian blind drive device described above.

[0038] In summary, by placing the drive motor 1 on one side of the curtain track 31, and arranging the drive motor 1 and the curtain track 31 side-by-side in the vertical direction, the overall length of the Venetian blind drive device is effectively reduced, making the Venetian blind drive device adaptable to more diverse application scenarios. Furthermore, by placing the drive motor 1 outside the curtain track 31, maintenance and disassembly of the drive motor 1 are facilitated. Additionally, the connection between the drive motor 1 and the curtain track 31 is reinforced by the stabilizing connector 4, ensuring a stable connection between the drive motor 1 and the curtain track 31.

[0039] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
