Description

Technical Field

[0001] This utility model relates to the field of intelligent lifting window technology, specifically a lifting window with an electric spinning mesh structure. Background Technology

[0002] With China's rapid socio-economic development, people's demands for quality of life in their homes are increasing. Windows, as an important structural element of buildings, play a crucial role in connecting the exterior to the interior, providing lighting, ventilation, and partitioning. To improve ease of use, many modern homes opt for more convenient electric windows. Intelligent electric lift windows are a common type of window in buildings. They are controlled by an electric motor to open and close, eliminating the need for manual operation. Users can easily control the window's raising and lowering with a simple operation. Compared to traditional manual windows, electric lift windows offer a more convenient and comfortable user experience, making them increasingly popular with families.

[0003] To protect the window space after it is opened, a protective screen structure is usually installed at the top of the lift window. For the protective screen, most existing lift windows adopt a roller-mounted installation structure, which uses an electric roller to drive the screen up and down. During the process, the screen is mainly lowered by gravity. Although there is a groove for guidance, the movement stability is still not good and it is easy to get stuck. Furthermore, since the opening part of the lift window is located at the bottom of the window, the screen needs to be fully lowered to cover the opening. The fully lowered screen will block the entire window, which will not only block the view but also seriously affect the lighting of the window, making it very inconvenient to use. Therefore, a lift window with an electric spinning screen structure is proposed. Utility Model Content

[0027] Example

[0028] Please see Figure 1-6 This utility model provides a technical solution: a lifting window with an electric spinning mesh structure, including a mounting frame 1, a window body mechanism and a window screen mechanism. The window body mechanism includes a fixed window body 2, a lifting window body 3, a window body drive motor 4, a first transmission pulley 5 and a first transmission toothed belt 6. The fixed window body 2 is fixedly installed on the upper middle part of the mounting frame 1, and serves as a fixed protective window body structure for sealing and protecting the upper part of the window.

[0029] The lifting window 3 is driven to move and lift in the middle of the mounting frame 1 by the window drive motor 4 in conjunction with the first transmission pulley 5 and the first transmission toothed belt 6. Specifically, see attached... Figure 3 As shown, to facilitate the guiding installation of the lifting window 3, a window guide groove is provided on the inner frame side of the mounting frame 1. The end of the lifting window 3 is slidably fitted into the inner side of the window guide groove. The window drive motor 4 is a geared motor.

In order to facilitate the working connection, a window drive connecting block is fixedly installed in the middle of both ends of the lifting window 3. The window drive connecting block is fixedly installed to the drive connecting seat in the middle of the first transmission toothed belt 6 by bolts. The pulleys and toothed belt form a drive transmission structure to drive the lifting window 3 to open and close. The toothed belt structure is supported and tensioned by the paired pulleys, which can improve the stable drive support of the lifting window 3 and greatly improve the working stability of the device.

[0030] The window screen mechanism includes a protective screen 7, a screen drive motor 8, a second transmission pulley 9, a second transmission toothed belt 10, a screen roll 11, and a tension spring 12. The protective screen 7 has a multi-mesh structure in the middle, which allows for ventilation while blocking external objects and obstructing the view. The protective screen 7 is wound and stored on the lower part of the mounting frame 1 via the screen roll 11. See attached diagram for details. Figure 3 As shown, to facilitate the connection and installation of the mesh roll 11, an installation groove 15 is provided at the lower part of the mounting frame 1. The mesh roll 11 is fixedly and rotatably installed inside the installation groove 15. The lower part of the protective mesh 7 is wound and installed with the mesh roll 11. The protective mesh 7 adopts a bottom-mounted installation structure. The protective mesh 7 is wound and stored by the mesh roll 11 located at the lower part of the mounting frame 1. After installation, the structure is not exposed, and the upper part of the protective mesh 7 is perfectly fitted and hidden with the window after storage, which has excellent integrated aesthetics and greatly improves the decorative aesthetics of the device. In order to seal and protect the installation groove 15, a groove cover 16 is fixedly installed on the lower opening side of the installation groove 15 by bolts.

[0031] The tension spring 12 is connected to the shaft end of the mesh roll 11 for tensioning, as detailed in the attached diagram. Figure 5 As shown, the tension springs 12 are arranged in pairs. The upper parts of the two sets of tension springs 12 are symmetrically fixed to both sides of the mounting frame 1 by support blocks. The lower parts of the tension springs 12 are fixedly installed with traction ropes 14, as shown in the attached figure. Figure 6 As shown, a drive wheel 13 is fixedly installed at the shaft end of the mesh roll 11, and the lower end of the traction rope 14 is wound around the upper part of the drive wheel 13. The tension spring 12 stores the force to provide a reset driving force for the rotation of the mesh roll 11, which can ensure that the protective mesh 7 is always in a taut state during the winding and unwinding process.

[0032] The upper part of the protective mesh 7 is driven by the mesh drive motor 8 in conjunction with the second transmission pulley 9 and the second transmission toothed belt 10 to move and lift, and is installed in the middle of the mounting frame 1. Specifically, see attached... Figure 5As shown, the mesh drive motor 8 is a geared motor. The reducer of the mesh drive motor 8 is fixedly installed on the upper part of the mounting frame 1 by bolts. Output shafts are provided on both sides of the reducer of the mesh drive motor 8. The second transmission pulleys 9 are divided into upper and lower groups. The two upper groups of second transmission pulleys 9 are fixedly installed on the two shaft ends of the mesh drive motor 8, and the two lower groups of second transmission pulleys 9 are fixedly mounted on the two sides of the mounting frame 1 by shaft support. The second transmission toothed belt 10 is installed on the upper part of the two groups of first transmission pulleys 5. The upper end seat of the protective mesh 7 is fixedly installed to the drive connecting seat in the middle of the first transmission pulley 5 by bolts. In order to facilitate the sliding and guiding of the protective mesh 7, a window screen guide groove is provided on the inner frame side of the mounting frame 1. The upper end seat of the protective mesh 7 slides into the inner side of the window screen guide groove. The upper end seat of the protective mesh 7 is fixedly installed to the drive connecting seat in the middle of the first transmission pulley 5 by bolts. The protective mesh 7 is lower-mounted. The installation structure utilizes a mesh roll 11 located at the lower part of the mounting frame 1 to wind and store the protective mesh 7. With the traction drive of the pulley and toothed belt structure, the protective mesh 7 can be moved and unfolded from the bottom. The operation can be adjusted to half-window or full-window shading as needed. In the half-window shading state, while ensuring ventilation, the upper part of the window remains transparent for light and view. In the full-window shading state, the protective mesh 7 covers the entire window, ensuring both privacy and concealment. This flexible operation meets the needs of different scenarios. For convenient window operation control, a touch screen 18 is provided on the side of the mounting frame 1. To improve the central support strength of the mounting frame 1, a reinforcing beam 17 is fixedly installed in the center of the mounting frame 1. To enhance the decorative effect of the window, a lighting strip is installed below the reinforcing beam 17. Furthermore, as a functional extension, anti-pinch sensors, rain sensors, and wind sensors can be installed on the upper part of the window to achieve intelligent opening and closing of the window.

[0033] Working principle or structural principle: During operation, the window is controlled via the touch screen 18 or remote control terminal. When the window is opened, the window drive motor 4 drives the lifting window 3 upward through the first transmission pulleys 5 on both sides and the first transmission toothed belt 6. At the same time, the screen drive motor 8 drives the protective screen 7 upward through the second transmission pulley 9 and the second transmission toothed belt 10. During the process, the upper part of the protective screen 7 is pulled upward through the two sets of second transmission toothed belts 10. At the same time, the screen roll 11 is pulled and rotates, causing the drive pulley 13 to wind the traction rope 14 to stretch and store the tension spring 12. The upward traction combined with the downward pull of the tension spring 12 keeps the protective screen 7 in a stable tension state. After the action, the lifting window 3 rises to the upper part of the mounting frame 1, and the window is in the open state. At the same time, the protective screen 7 rises upward. The protective screen 7 is moved to the reinforcing beam 17 in the middle of the mounting frame 1 to shield and protect the opened window. In the half-window shielding state, the protective screen 7 only shields the lower opening area of ​​the window, ensuring ventilation while maintaining light transmission and visibility in the upper part of the window. This is the default working mode of the device. Through preference settings and subsequent operations, the protective screen 7 can be in a retracted or fully extended working state. In the fully extended state, the protective screen 7 covers the entire window, ensuring the shielding and privacy of the window. Similarly, when the lifting window 3 moves down to close, the protective screen 7 is driven to move down. During the process, the tension spring 12 pulls the screen roll 11 to automatically rotate and wind and tighten the moving protective screen 7. After being retracted, the upper end of the protective screen 7 fits perfectly into the groove at the bottom of the mounting frame 1, giving the window an excellent integrated aesthetic.

[0034] In summary, this lifting window adopts a toothed belt drive structure. The drive transmission structure, consisting of pulleys and a toothed belt, drives the opening and closing of the lifting window body 3 and the protective screen 7. The toothed belt structure, supported and tensioned by paired pulleys, provides stable drive support for the lifting window body 3 and the protective screen 7, greatly improving the working stability of the device. The protective screen 7 adopts a bottom-mounted installation structure. A screen roll 11 located at the lower part of the mounting frame 1 winds and stores the protective screen 7. Combined with the traction drive of the pulleys and toothed belt structure, the protective screen 7 can be moved and unfolded from below, allowing for operation as needed. The system can be adjusted to half-window and full-window shading states. In the half-window shading state, the window can be ventilated while maintaining light transmission and visibility in the upper part of the window. In the full-window shading state, the protective screen 7 covers the entire window to ensure the window is covered and provides privacy. The system is flexible and can meet the needs of different scenarios. The protective screen 7 is integrated into the mounting groove 15 at the lower part of the mounting frame 1 by being wound by the screen roll 11. After installation, the structure is not exposed, and when stored, the upper part of the protective screen 7 fits perfectly into the window and is hidden, which has excellent integrated aesthetics and greatly improves the decorative aesthetics of the device.
