Description

Technical Field

[0001] This utility model relates to the field of Venetian blind technology, specifically to a flat-opening electric Venetian blind. Background Technology

[0002] Venetian blinds, as a common light-blocking and light-regulating device, are widely used in various architectural spaces, such as residences, offices, and commercial shops. With the improvement of people's living standards and the increasing demands for indoor comfort, the performance and user experience of Venetian blinds are receiving more and more attention, with the flatness of the blinds when rotated becoming one of the key indicators of their quality.

[0003] Currently available Venetian blinds suffer from numerous defects in terms of the smoothness of their rotation. Traditional manual Venetian blinds rely on manual manipulation of the slats for angle adjustment. Due to the lack of an effective linkage mechanism between the slats, it's difficult to ensure that all slats rotate synchronously. In practice, some slats frequently rotate at inconsistent angles. While some existing motorized Venetian blinds have addressed the issue of ease of operation to some extent, their smoothness during rotation remains unsatisfactory. Furthermore, the drive systems of some motorized Venetian blinds are not precisely designed, resulting in deviations in power transmission. When the motor drives the slats to rotate, the uneven driving force on each slat prevents them from reaching the predetermined angle simultaneously, causing uneven rotation. Utility Model Content

[0049] Compared with the prior art, the beneficial effects of this application are as follows:

[0050] The electric Venetian blind described in this application works in concert through two sets of drive devices, a folding structure connecting the drive devices, and a controller. The drive devices drive the transmission components to move, and the folding units evenly distributed on the transmission components correspond one-to-one with the veils. The folding units can move synchronously, pushing the veils to fold synchronously and evenly, avoiding the situation where some veils have inconsistent folding angles, greatly improving the flatness of the veils' folding, and thus solving the problem that traditional manual Venetian blinds lack a linkage mechanism and that the electric Venetian blind drive system has deviations, resulting in uneven veils folding.

[0051] This application sets a first limiting component at the connection between the transmission component and the drive device. The outer teeth of the upper and lower rotating disks mesh with the inner teeth on the connection side of the transmission component, ensuring a stable connection between the transmission component and the rotating disk. This prevents the transmission component from slipping during power transmission, ensuring the accuracy and stability of the movement, and enabling the venetian blinds to accurately reach the predetermined flip angle. This solves the problem of uneven venetian blind flipping caused by power transmission deviation in existing electric venetian blinds.

[0052] This application sets a second limiting component in the transmission part. The cooperation between the slide rail and the slide groove restricts the movement trajectory of the transmission part, so that the transmission part can only slide smoothly along the direction of the slide rail. This avoids the transmission part from deviating or shaking during the movement, enhances the stability of the entire Venetian blind system, and further ensures the flatness of the Venetian blind rotation. This solves the problem that existing Venetian blinds may have component shaking or displacement during operation, which affects the flatness.

[0053] This application sets a third limiting component between the second link and the rotating rod. The cooperation of the limiting plate and the annular limiting plate restricts the relative movement range between the rotating rod and the second link, ensuring precise angle control of the venetian blinds during the page turning process, effectively preventing excessive flipping or shaking of the venetian blinds, and ensuring the stability of the overall movement of the venetian blinds and the flatness of the venetian blind flipping.

[0102] The limiting plate 71 is slidably connected to the limiting groove.

[0103] It should be noted that:

[0104] The electric Venetian blind described in this application uses a drive device to move a transmission component. The page-turning unit on the transmission component pushes the veils to turn smoothly. Each limiting component ensures the stability and accuracy of the movement. The specific movement process is as follows:

[0105] Drive motor 12 starts: When the wireless remote control (controller) is pressed, the bidirectional geared motor (drive motor) starts working. The output end of drive motor 12 drives the connected upper or lower rotating disk (drive wheel) to rotate. Because the upper and lower rotating disks are respectively connected to the upper connecting rod 1 and the lower connecting rod, the upper and lower connecting rods will rotate around their respective axial center lines with the rotating disks. The two ends of the transmission component are respectively connected to the upper and lower rotating disks on the same side, and the internal teeth set at the connection point mesh with the external teeth on the rotating disk. Driven by the rotating disk, the drive part 4 in the transmission component will move synchronously with the corresponding rotating disk, and the transmission part 5 as a whole will move towards the window frame or towards the window frame. The transmission part 5 of the transmission component is provided with multiple page-turning units at intervals, and the number of page-turning units is the same as the number of blinds and corresponds one-to-one. When the transmission component moves, the page-turning units move accordingly. Among them, the first connecting rod 11 of the first page-turning unit is connected to the transmission part 5. When the transmission part 5 moves towards the window frame or towards the window frame, it will drive the first connecting rod 11 to move synchronously. The first connecting rod 11 is rotatably connected to the first swing rod 10, and the second connecting rod 8 is rotatably connected to the second swing rod 9. The ends of the first swing rod 10 and the second swing rod 9 that are close to each other are also rotatably connected. The first connecting rod 11 will move closer to or further away from the second connecting rod 8 located in the same page-turning unit, thereby reducing or increasing the angle formed by the first swing rod 10 and the second swing rod 9. The second swing rod 9 drives the rotating rod 72 to rotate, and the rotating rod 72 will push the louver 2 to rotate around its mounting point, realizing the page-turning action of the louver 2. Since the page-turning units are evenly distributed and move synchronously along the transmission component, multiple louvers 2 can turn pages synchronously and smoothly.

[0106] Throughout the movement, the first limiting component consists of external teeth on the upper and lower rotating discs and internal teeth on the connecting side of the transmission component. These two components mesh with each other to ensure a stable connection between the transmission component and the rotating discs, preventing slippage during power transmission and ensuring the accuracy and stability of the movement. The second limiting component includes a slide rail on one side of the transmission unit and a matching slide groove on the mounting base. The slide rail and slide groove are slidably connected, limiting the movement trajectory of the transmission unit and ensuring that the transmission component can only slide smoothly along the slide rail, preventing deviation or swaying during movement. The third limiting component consists of a limiting disc and an annular limiting plate, respectively connected to the opposite ends of the second connecting rod and the rotating rod. The limiting plate is slidably connected to the annular limiting groove on the limiting disc, limiting the relative movement range between the rotating rod and the second connecting rod, ensuring precise angle control during louvering, preventing excessive louvering or swaying, and ensuring the overall stability of the venetian blind's movement.
