Description

Technical Field

[0001] This utility model belongs to the field of invisible screen technology, specifically relating to a new type of electric windproof invisible screen based on voice control. Background Technology

[0002] Invisible screens are screens with automatically retractable mesh, mainly used for ventilation and mosquito prevention. The frame is tightly attached to the window frame. When in use, the screen is pulled down, and when not in use, the screen automatically retracts into the mesh box, saving space and providing strong sealing, which coordinates with high-end home decoration.

[0003] Traditional retractable screens are mostly operated manually, requiring users to pull or turn knobs to adjust the opening and closing of the screen. This lack of convenience is particularly problematic in high-rise buildings or with large windows, where manual control is laborious and slow to respond. Furthermore, traditional screens are prone to swaying, making noise, or even coming off track in strong winds due to loose mesh, resulting in poor wind resistance. While existing electric screens improve convenience with motor-driven operation, they generally lack a dynamic adjustment mechanism for mesh tension. Over time, the mesh tends to curl and loosen, affecting sealing and lifespan. In addition, existing products lack sufficient intelligence and cannot integrate with smart home systems, failing to meet users' emerging needs for voice interaction and remote control. Utility Model Content

[0004] The purpose of this invention is to provide a novel electric windproof invisible screen window based on voice control, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel voice-controlled motorized windproof and invisible screen window includes:

[0007] Mounting bracket, wherein a retractable screen roll is rotatably connected between the two sides of the mounting bracket via a pivot;

[0008] A movable groove is formed on one inner wall of the mounting frame, and a lead screw is rotatably connected between the upper and lower inner walls of the movable groove.

[0009] A lead screw nut, wherein the lead screw nut is threaded onto the circumferential surface of the lead screw;

[0010] A drive rod is fixedly connected to the lower end of the invisible screen roll, and the drive rod is fixedly connected to the lead screw nut;

[0011] The tensioning mechanism, located on the upper side of the mounting bracket, is used to abut against the invisible screen roll to prevent it from loosening.

[0012] In a preferred embodiment of this utility model, the tensioning mechanism comprises a force-bearing plate, a fixed frame, a rotating frame, an extension spring, a tensioning wheel, and a vertical rod. The fixed frame is fixedly connected to the upper end of the mounting frame, the vertical rod movably passes through the lower end of the fixed frame and extends downward, the rotating frame is fixedly connected to the lower end of the vertical rod, the tensioning wheel is rotatably connected to the rotating frame via a rotating rod, the force-bearing plate is fixedly connected to the upper end of the vertical rod, and the extension spring is sleeved on the circumferential surface of the vertical rod.

[0013] As a preferred embodiment of this utility model, the lower inner wall of the movable groove is provided with an installation groove, and a motor is fixedly connected in the installation groove. The output end of the motor is fixedly connected to a lead screw.

[0014] As a preferred embodiment of this utility model, a limiting rod is provided on one inner wall of the mounting bracket, and a limiting block is fixedly connected to one end of the driving rod, with the limiting block slidably connected in the limiting groove.

[0015] As a preferred embodiment of this utility model, a limiting rod is fixedly connected between the upper and lower inner walls of the limiting groove, and a vertical hole is provided at the upper end of the limiting block, and the limiting block is slidably connected to the circumferential surface of the limiting rod through the vertical hole.

[0016] As a preferred embodiment of this utility model, two anti-rotation rods are fixedly connected to the upper end of the rotating frame, and two anti-rotation holes are opened at the upper end of the fixed frame, with the two anti-rotation rods slidably connected in the two anti-rotation holes respectively.

[0017] As a preferred embodiment of this utility model, each end of the mounting bracket is fixedly connected to two connecting blocks, and each of the multiple connecting blocks is threadedly connected to a threaded rod.

[0018] In a preferred embodiment of this utility model, a storage shell is fixedly connected to one end of the mounting bracket, and a torque spring is fixedly connected between one end of the rotating shaft and one inner wall of the storage shell.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In this solution, the integrated voice recognition module in the motor allows users to open and close the screen window using natural language commands. This is especially suitable for scenarios where people have limited mobility or whose hands are occupied, significantly improving ease of operation. The screw and nut pair drives the screen to retract and extend, which has higher positioning accuracy and wind load resistance compared to traditional gear or belt drives, preventing the screen from shifting or getting stuck.

[0021] 2. In this solution, the tensioning wheel applies continuous pressure through the extended spring, which compensates in real time for the slack caused by temperature changes or mechanical wear of the screen, ensuring that the screen remains taut in strong winds, reducing abnormal noise and structural vibration. The combination of the connecting block and the threaded rod enables the quick fixing of the mounting bracket and adapts to different window frame sizes. The storage shell integrates a torque spring, which automatically resets when the screen rolls back, reducing the frequency of manual intervention. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-4 The present invention provides the following technical solution:

[0031] A novel voice-controlled motorized windproof and invisible screen window includes:

[0032] Mounting bracket 1, with invisible screen roll 4 rotatably connected between the two sides of mounting bracket 1 via a pivot;

[0033] The movable groove 16 is formed on one inner wall of the mounting bracket 1, and a lead screw 15 is rotatably connected between the upper and lower inner walls of the movable groove 16.

[0034] The lead screw nut is threaded onto the circumferential surface of the lead screw 15.

[0035] Drive rod 18 is fixedly connected to the lower end of invisible screen roll 4, and drive rod 18 is fixedly connected to screw nut;

[0036] The tensioning mechanism is located on the upper side of the mounting frame 1 and is used to abut against the invisible screen roll 4 to prevent it from loosening. The tensioning mechanism consists of a force plate 8, a fixed frame 5, a rotating frame 6, an extension spring 9, a tension wheel 10, and a vertical rod 19. The fixed frame 5 is fixedly connected to the upper end of the mounting frame 1. The vertical rod 19 moves through the lower end of the fixed frame 5 and extends downward. The rotating frame 6 is fixedly connected to the lower end of the vertical rod 19. The tension wheel 10 is rotatably connected to the rotating frame 6 through a rotating rod. The force plate 8 is fixedly connected to the upper end of the vertical rod 19. The extension spring 9 is sleeved on the circumferential surface of the vertical rod 19.

[0037] In a specific embodiment of this utility model, the mounting frame 1 supports the invisible screen roll 4 via two rotating shafts. The end of the screen is fixedly connected to the driving rod 18. A vertical moving groove 16 is opened on the inner side of the mounting frame 1, and a lead screw 15 driven by a motor 17 is installed in the groove. The lead screw nut is rigidly connected to the driving rod 18. After the user issues a voice command, the controller drives the motor 17 to rotate the lead screw 15, causing the lead screw nut and the driving rod 18 to move up and down along the moving groove 16, thereby unfolding or rewinding the screen. The tensioning mechanism is located at the top of the mounting frame 1, and the tensioning wheel 10 presses against the outer surface of the invisible screen roll 4 to prevent it from being rolled up due to inertia. The screen is loosened by force or wind. The fixing frame 5 is welded to the top of the mounting frame 1. The vertical rod 19 passes through the through hole of the fixing frame 5 and is fixed to the rotating frame 6. The tension wheel 10 is installed on the lower part of the rotating frame 6 through the rotating shaft. It can rotate freely to reduce the frictional resistance with the screen. The extension spring 9 is sleeved on the outside of the vertical rod 19. Its two ends abut against the lower surface of the fixing frame 5 and the upper surface of the rotating frame 6, respectively, to provide downward elastic pressing force for the tension wheel 10. When the diameter of the invisible screen roll changes due to the expansion and contraction of the screen, the tension wheel 10 adaptively adjusts the pressing position under the action of the extension spring 9 to ensure that the screen is always in a taut state.

[0038] Please refer to the details. Figure 2The lower inner wall of the moving groove 16 is provided with an installation groove, and a motor 17 is fixedly connected in the installation groove. The output end of the motor 17 is fixedly connected to the lead screw 15. A limit rod 13 is provided on one side inner wall of the mounting bracket 1. One end of the driving rod 18 is fixedly connected to a limit block 12. The limit block 12 is slidably connected in the limit groove 14. The limit rod 13 is fixedly connected between the upper and lower inner walls of the limit groove 14. A vertical hole is provided at the upper end of the limit block 12, and the limit block 12 is slidably connected to the circumferential surface of the limit rod 13 through the vertical hole.

[0039] In this embodiment: the motor 17 is embedded in the mounting groove at the bottom of the moving groove 16, and its output shaft is coaxially connected to the lead screw 15 through a coupling. The motor 17 is preferably a stepper motor or a servo motor, and is used in conjunction with an encoder to achieve precise position control. The controller analyzes the target opening degree according to the voice command, drives the motor 17 to rotate forward and backward, and drives the lead screw nut and the mesh to move precisely to the designated position. A vertical limiting groove 14 is opened on the inner side wall of the mounting frame 1, and a limiting rod 13 is welded inside it. The end of the driving rod 18 is fixedly connected to the limiting block 12. The limiting block 12 has a through hole and is sleeved on the outer surface of the limiting rod 13. When the lead screw 15 drives the driving rod 18 to move, the limiting block 12 slides along the limiting rod 13 to limit the lateral displacement of the mesh and avoid track deviation caused by uneven force.

[0040] Please refer to the details. Figure 2 Two anti-rotation rods 7 are fixedly connected to the upper end of the rotating frame 6, and two anti-rotation holes are opened at the upper end of the fixed frame 5. The two anti-rotation rods 7 are slidably connected in the two anti-rotation holes respectively.

[0041] In this embodiment, two anti-rotation rods 7 are welded to the top of the rotating frame 6. Their diameter is slightly smaller than the anti-rotation hole on the fixed frame 5. When the tension wheel 10 is pressed, the anti-rotation rod 7 slides in the anti-rotation hole, preventing the rotating frame 6 from rotating around the axis of the vertical rod 19. This ensures that the tension wheel 10 always maintains parallel contact with the surface of the invisible screen roll 4, avoiding screen wear caused by local stress concentration.

[0042] Please refer to the details. Figure 3 Two connecting blocks 2 are fixedly connected to both ends of the mounting bracket 1. Threaded rods 3 are threadedly connected to the multiple connecting blocks 2. A storage shell 11 is fixedly connected to one end of the mounting bracket 1. A torque spring 20 is fixedly connected between one end of the rotating shaft and the inner wall of one side of the storage shell 11.

[0043] In this embodiment: L-shaped connecting blocks 2 are welded to the four corners of the mounting bracket 1. Each connecting block 2 has a threaded hole. During installation, the threaded rod 3 is screwed into the pre-drilled hole in the window frame, and the connecting block 2 is tightened by tightening the nut to achieve quick fixation of the screen. This design supports drilling-free installation and is compatible with various window frame materials such as PVC and aluminum alloy. The storage shell 11 is fixed to the side wall of the mounting bracket 1. A torque spring 20 is installed inside the storage shell 11. One end of the torque spring 20 is fixed to the end of the rotating shaft, and the other end is anchored to the inner wall of the storage shell 11. When the screen is rolled up, the torque spring 20 stores energy; when the screen is unfolded, the spring releases energy to assist the motor 17 in driving, reducing power consumption and improving system response speed.

[0044] Working principle and usage process of this utility model:

[0045] Mounting bracket 1 supports the concealed screen roll 4 via two rotating shafts. The end of the screen is fixedly connected to the drive rod 18. A vertical moving groove 16 is opened on the inner side of mounting bracket 1, and a lead screw 15 driven by motor 17 is installed in the groove. The lead screw nut is rigidly connected to the drive rod 18. After the user issues a voice command, the controller drives motor 17 to rotate lead screw 15, causing lead screw nut and drive rod 18 to move up and down along the moving groove 16, realizing the unfolding or rewinding of the screen. The tensioning mechanism is located at the top of mounting bracket 1, and the tensioning wheel 10 presses against the outer surface of the screen roll 4 to prevent it from loosening due to inertia or wind. The fixing frame 5 is welded to the top of the mounting frame 1. The vertical rod 19 passes through the through hole of the fixing frame 5 and is fixedly connected to the rotating frame 6. The tension wheel 10 is installed on the lower part of the rotating frame 6 through the rotating shaft and can rotate freely to reduce the frictional resistance with the screen. The extension spring 9 is sleeved on the outside of the vertical rod 19, and its two ends abut against the lower surface of the fixing frame 5 and the upper surface of the rotating frame 6 respectively, providing a downward elastic pressing force for the tension wheel 10. When the diameter of the invisible screen roll 4 changes due to the expansion and contraction of the screen, the tension wheel 10 adaptively adjusts the pressing position under the action of the extension spring 9 to ensure that the screen is always in a taut state.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
