Description

Technical Field

[0001] This invention relates to the field of home furnishing technology, and in particular to an automatic window closing device that combines rainwater detection and weather forecast. Background Technology

[0002] With the development of smart home technology, automatic window control systems have become an important component for improving living comfort and security. Currently, there are various automatic window closing devices on the market, which mainly use rain or humidity sensors to detect changes in the outside weather. When rainfall is detected, the system automatically drives a motor to close the window to prevent rainwater from entering the room and causing property damage.

[0003] However, existing technologies still have certain shortcomings: most current automatic window closing devices use gears and racks, wire rope traction, or direct drive of the window frame to open and close windows. When the motor or transmission mechanism malfunctions, users often find it difficult to operate manually, resulting in windows failing to open or close properly and posing safety hazards. Some existing devices rely solely on rain sensors for window closing control, but rain sensors can only sense the current rainfall status and cannot predict upcoming rainfall, leading to a lag in window closing response. Furthermore, after installation, the transmission components of existing automatic window closing devices are often rigidly connected to the window. When the system is in standby or power-off mode, users find it difficult to easily push or pull the window manually, limiting the flexibility of daily use.

[0004] Therefore, in order to address the above problems, this invention proposes an automatic window closing device that can combine rainwater sensor and weather forecast information for joint decision-making, has a highly reliable mechanical transmission structure, and is easy to operate manually. Summary of the Invention

[0005] The present invention aims to provide an automatic window closing device that combines rainwater detection and weather forecast to solve the problem that existing window closing devices cannot be manually operated when there is a power outage or malfunction due to rigid connection of transmission components, as well as the problems of lag and insufficient decision-making accuracy of a single rainwater sensor.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic window closing device combining rainwater detection and weather forecasting includes a base, a window frame and a fixed window fixedly connected to the top of the base, and a sliding window slidably connected to the top of the base. Both the sliding window and the fixed window are located inside the window frame. A sliding groove is provided on the top of the base. A bottom block is connected to the bottom of the sliding window via a connecting rod. The connecting rod slides within the sliding groove. The bottom block is located inside the base and is connected to a connecting plate. The connecting plate is connected to a sliding rod. A first hemispherical block is connected to the end of the sliding rod, and a second hemispherical block is slidably connected to the sliding rod. The second hemispherical block is connected to the connecting plate via a spring. The base is equipped with a sliding sleeve and a window opening / closing motor. The inner diameter of the sliding sleeve is larger than that of the first and second hemispheres. A fixed frame is connected to the outside of the sliding sleeve, and a sliding channel is connected to the fixed frame. The sliding channel extends into the interior of the sliding sleeve, and a backing plate is slidably connected inside the sliding channel. The side of the backing plate closest to the first hemisphere is arc-shaped. The backing plate is connected to the side wall of the sliding channel by a spring. A sleeve block is connected to the sliding sleeve. The window opening / closing motor is fixedly connected to the center of the base. Threaded rods are rotatably connected to the sleeve block on both sides of the window opening / closing motor.

[0008] Furthermore, the sliding window is connected to a base plate, the base plate is rotatably connected to a pivot, a blackout curtain is connected around the pivot, the pivot has a spline groove inside, a blackout motor is connected to the center of the window frame, spline shafts are rotatably connected to both sides of the blackout motor, and the two spline shafts are slidably connected in the spline groove.

[0009] Furthermore, a rain sensor and a light sensor are connected to the side of the base. The rain sensor is used to control the window opening and closing motor, and the light sensor is used to control the shading motor.

[0010] Furthermore, the base plate is detachably connected to the sliding window, and the light-blocking motor is detachably connected to the window frame.

[0011] Furthermore, the fixed frame has four sliding channels arranged in a circular array, and each of the four sliding channels is slidably connected to abutment plates, and the four abutment plates have the same structure.

[0012] Furthermore, fixing rods are fixedly connected to both sides of the connecting rod, with one end of the fixing rod connected to the connecting rod and the other end fixedly connected to the bottom of the sliding window.

[0013] Furthermore, a limiting rod is fixedly connected inside the base, and sliding collars are fixedly connected to the sides of the bottom block and the sliding sleeve, with the sliding collars slidably connected to the limiting rod.

[0014] Furthermore, the connecting plate and the base plate are detachably connected.

[0015] A control system for an automatic window closing device that combines rainwater detection and weather forecasting includes a central controller, a control terminal, a motor drive module, a communication module, and a power supply module. The central controller is used to read and process data from sensors, the control terminal is used to directly control the motor and view sensor data, the motor drive module is used to transmit signals from the central controller to the motor, the communication module is used to communicate with external networks, and the power supply module is used to power internal electronic devices.

[0016] Furthermore, the communication module is used to transmit weather forecast information to the central controller for processing.

[0017] The principle and beneficial effects of this technical solution:

[0018] The mechanical transmission principle of the device in this invention is as follows: The device uses a window opening / closing motor to drive the sliding window, thereby opening and closing the window. By incorporating a sliding sleeve, abutment plate, a first hemisphere, a second hemisphere, and a sliding rod, it achieves compatibility between manual and electric window opening / closing without interference. Specifically, when the sliding sleeve moves towards the connecting plate, the arc-shaped side of the abutment plate can pass over the hemisphere and enter between the first and second hemispheres. At this point, pulling the sliding sleeve in the opposite direction opens the window. If it continues to move to the right until it is between the second hemisphere and the connecting plate, pushing the sliding sleeve closes the window. Since the sliding sleeve is located at both ends when not in operation, the abutment plate is not in contact with the hemisphere, allowing the user to freely push and pull the window manually without being restricted by the motor.

[0019] Intelligent control principle: In the device system of this invention, a rain sensor detects real-time rainfall, a light sensor detects ambient light intensity, and a communication module connects to the Internet to obtain weather forecast data. A dual verification strategy of weather forecast and rain sensor is adopted. For example, windows are closed in advance before the forecast rainfall. If the rain sensor does not detect rainfall after the forecast time (i.e., false alarm), the windows are automatically opened to restore ventilation. The rain sensor has higher control authority and immediately closes the windows once it detects actual rainfall.

[0020] Beneficial effects:

[0021] (1) The device of the present invention uses a clutch design of the first hemisphere block, the second hemisphere block and the abutment plate. In the non-working state, the sliding sleeve is completely disengaged from the hemisphere block. The window and the transmission mechanism are not rigidly connected. The user can manually push and pull the window at any time. Even if the power is cut off or the motor fails, it will not affect normal use, which greatly improves safety and convenience.

[0022] (2) This invention combines the predictive nature of weather forecasts with the real-time nature of rain sensors, and makes decisions through dual verification. Weather forecasts can close windows in advance to compensate for the lack of sensor response lag; rain sensors have higher control authority and can immediately force the windows to close once actual rainfall is detected, effectively avoiding misoperation caused by weather forecast errors. The two work together to balance foresight and accuracy.

[0023] (3) The device of the present invention has a simple structure and stable and reliable operation. The device of the present invention adopts the transmission method of threaded rod driving sliding sleeve, with fewer parts, compact structure and fewer failure points; the abutment plate and hemispherical block only contact each other momentarily when the window is opened and closed, and are in a separated state most of the time, resulting in less wear and longer service life. With the guidance and reinforcement of the limit rod and the fixing rod, it ensures smooth and stable long-term reciprocating operation and low maintenance cost.

[0024] (4) The device of the present invention integrates the linkage control of the blackout curtain on the basis of automatic window closing. Through the sliding cooperation of the spline shaft and the rotating shaft, the blackout curtain moves synchronously when the window is moved horizontally, and the blackout motor can independently control the curtain to rise and fall. Combined with the light sensor, it can automatically shade the sun when the window is closed, or lower the blackout curtain separately in strong light, so as to realize intelligent control of multiple scenarios such as rain protection, sun protection, and light adjustment.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0035] like Figures 1-7 The device shown is an automatic window closing device that combines rainwater detection and weather forecast. It includes a base 1, and a control mechanism for opening and closing the window is installed inside the base 1. A window frame 2 is fixedly connected to the top of the base 1. A fixed window 3 and a sliding window 4 are fixedly connected inside the window frame 2. The fixed window 3 is fixedly connected to the left and right ends of the window frame 2, and the sliding window 4 is slidably connected inside the window frame 2. The bottom of the sliding window 4 is slidably connected to the top of the base 1, and the top of the sliding window 4 is slidably connected to the inside of the window frame 2.

[0036] A base block 6 is connected to the bottom center of the sliding window 4 via a connecting rod 5. Inclined fixing rods 7 are connected to both sides of the connecting rod 5. One end of the fixing rod 7 is fixedly connected to the connecting rod 5, and the other end is fixedly connected to the bottom of the sliding window 4. The fixing rods 7 are provided to increase stability and improve the stability of the sliding window 4 during movement. A sliding groove 8 is provided at the top of the base 1, and the connecting rod 5 is slidably connected inside the sliding groove 8. The sliding groove 8 connects the outside to the inside of the base 1. The sides of the base block 6 are detachably connected via bolts. A connecting plate 9 is connected to a sliding rod 10. One end of the sliding rod 10 is fixedly connected to the connecting plate 9, and the other end is fixedly connected to a first hemispherical block 11. A second hemispherical block 12 is slidably connected to the sliding rod 10. When the first hemispherical block 11 and the second hemispherical block 12 are in close contact, they can form a complete spherical structure. The second hemispherical block 12 is connected to the connecting plate 9 by a spring. The spring is sleeved on the sliding rod 10. Due to the spring, the second hemispherical block 12 will slide to the right or left. The spring returns the object to its initial position due to its elastic force. A sliding sleeve 13 is provided on the side of the hemispherical block. The inner diameter of the sliding sleeve 13 is slightly larger than that of the first hemispherical block 11 and the second hemispherical block 12, allowing the first hemispherical block 11 and the second hemispherical block 12 to enter. The depth of the sliding sleeve 13 is less than or equal to the length of the sliding rod 10, meaning that the end of the first hemispherical block 11 can abut against the bottom of the inner end of the sliding sleeve 13. A fixing frame 14 is fixedly connected to the outer side of the sliding sleeve 13. The fixing frame 14 has four sliding channels arranged in a circumferential array. 5. All four sliding channels 15 extend into the interior of the sliding sleeve 13. Each sliding channel 15 has a sliding abutment plate 16 slidably connected inside. The side of the four abutment plates 16 closest to the first hemisphere 11 is arc-shaped, while the side furthest from the first hemisphere 11 is vertical. One end of each abutment plate 16 is fixedly connected to the side wall of the sliding channel 15 via a spring. This structural arrangement allows for changing the position of the abutment plate 16 on the sliding rod 10 to select whether to move the sliding window 4 to the left or right. The specific principle is as follows: Figure 5For example, when the sliding sleeve 13 is moved to the right, the four abutment plates 16 can move to the right synchronously. Since the right side of the four abutment plates 16 is an arc-shaped structure and the left side of the first hemisphere block 11 is an arc-shaped structure, when the four abutment plates 16 abut against the first hemisphere block 11 and continue to move to the right, the four abutment plates 16 will spread outwards, thus entering the position between the first hemisphere block 11 and the second hemisphere block 12 from the left side of the first hemisphere block 11. At this time, if the sliding sleeve 13 is moved to the left, then the abutment plates 16... The vertical structure on the left side will contact and abut against the vertical structure on the right side of the first hemisphere 11. At this time, continuously pulling the sliding sleeve 13 to the left will cause the sliding window 4 to move to the left. If the sliding sleeve 13 continues to move to the right, due to the arc-shaped structure on the right side of the abutment plate 16 and the vertical structure on the left side of the second hemisphere 12, the abutment plate 16 can continue to move to the right to the position between the second hemisphere 12 and the connecting plate 9. Since the depth of the sliding sleeve 13 is less than or equal to that of the sliding rod 10, continuously moving the sliding sleeve to the right will allow it to continue moving to the right. When the first hemisphere 11 abuts against the leftmost end of the sliding sleeve 13, if the sliding sleeve 13 is moved to the right, it will cause the sliding window 4 to move to the right. The rightward and leftward movement of the sliding window 4 represents the opening and closing of the window. It should also be noted that when the abutment plate 16 is located between the second hemisphere 12 and the moving plate, continuously moving the sliding sleeve 13 to the left will allow the abutment plate 16 to move out to the left end of the first hemisphere 11. Specifically, when the abutment plate 16... When the abutment plate moves to the left between the second hemisphere 12 and the movable plate, it will first contact the second hemisphere 12, thereby pushing the second hemisphere 12 to the left, so that the left end of the second hemisphere 12 fits with the right end of the first hemisphere 11, thus forming a complete spherical structure. At this time, when the abutment plate 16 moves to the left, its left vertical structure will not contact the right vertical structure of the first hemisphere 11, so the abutment plate 16 can smoothly move from the right side of the first hemisphere 11 to the left side of the first hemisphere 11.

[0037] A sleeve block 17 is fixedly connected to the outside of the sliding sleeve 13. Sliding collars 18 are connected to the sides of both the sliding sleeve 13 and the base block 6. A limiting rod 19 is fixedly connected inside the base 1, and the limiting rod 19 passes through the sliding collars 18 inside the base 1. The limiting rod 19 is designed to improve the stability of the sliding process. A window opening / closing motor 20 is placed at the center of the base 1. The window opening / closing motor 20 is a dual-axis motor, and threaded rods 21 are rotatably connected to both sides of the window opening / closing motor 20. The threaded rods 21 on both sides of the window opening / closing motor 20 are threadedly connected to the sleeve blocks 17 on both sides. Therefore, when the window opening / closing motor 20 is in motion... When the threaded rods 21 on both sides rotate, they can cause the sliding blocks 6 on both sides to move closer or further apart. The sliding blocks 6 are fixedly connected to the sliding sleeve 13. That is, the window opening / closing motor 20 rotating the threaded rods 21 on both sides can cause the sliding sleeve 13 to move left or right. Therefore, based on the principle that the window opening / closing motor 20 drives the sliding sleeve 13 to move and the principle of changing the position of the abutment plate 16 on the sliding rod 10 to select whether to move the sliding window 4 to the left or right, we can control the opening and closing of the window by programming the window opening / closing motor 20. Specifically, the opening and closing programs both involve rotating the threaded rods 21. The sliding sleeves 13 on both sides move closer together and then move further apart back to their initial left and right positions. The difference lies in the distance the sliding sleeves 13 move when they move closer together. The window closing process: The window opening / closing motor 20 drives the threaded rods 21 on both sides to rotate, causing the sliding sleeves 13 on both sides to move closer together. This, in turn, pushes the sliding windows 4 on both sides closer together, thus closing the window. After the window is closed, the window opening / closing motor 20 controls the sliding sleeves 13 to move further apart back to their initial left and right positions. The window opening process: The window opening / closing motor 20 drives the threaded rods 21 on both sides to rotate. This causes the sliding sleeves 13 on both sides to move closer together, until the abutment plates 16 inside the sliding sleeves 13 move to the positions of the first hemispherical block 11 and the second hemispherical block 12 and stop. At this point, the window opening / closing motor 20 drives the sliding sleeves 13 to move away from each other, thus moving the closed sliding window 4 away from each other and opening the window. The advantage of this setting is that the sliding sleeves 13 are always located at the left and right ends, so manual opening and closing of the window will not be affected. At the same time, when no one is home and the window needs to be opened and closed, it can also be controlled by the program. It should be noted that when the sliding window 4 is not at the left and right ends, but at any position between the left and right ends, the closing process will not be affected, but the opening process may be affected. Therefore, the window opening program can be set to first perform the window closing program, so that the sliding window 4 and the sliding sleeves 13 are at the end positions, and then perform the window opening process, which can effectively ensure the completion of the window opening task.

[0038] In this invention, a light-blocking motor 22 is installed at the top center of the window frame 2. The light-blocking motor 22 is detachably connected to the window frame via bolts. The light-blocking motor 22 is also a dual-axis motor, with splined shafts 23 rotatably connected to both sides of the light-blocking motor 22. One end of the splined shaft 23 is connected to the light-blocking motor 22, and the other end is rotatably connected to the window frame 2. A base plate 24 is detachably connected to the top of the sliding window 4 via bolts. A rotating shaft 25 is rotatably connected to the base plate 24, and a light-blocking curtain 27 is connected to the rotating shaft 25 for light blocking. The curtain 27 is connected to a rotating shaft 25. The rotating shaft 25 has a splined groove 26 inside for a splined shaft 23 to pass through. The splined groove 26 passes through both ends of the rotating shaft 25, and the rotating shaft 25 is slidably connected to the splined shaft 23. Therefore, with this structure, the rotating shaft 25 can slide synchronously when the sliding window 4 slides. When it is necessary to open or lower the blackout curtain 27, simply start the blackout motor 22 to drive the splined shafts 23 on both sides to rotate. The splined shafts 23 then drive the rotating shaft 25 to rotate, thereby lowering or raising the blackout curtain 27. A rain sensor 28 and a light sensor 29 are provided on the side of the window frame 2. The rain sensor 28 and the light sensor 29 can control the window opening / closing motor 20 and the blackout motor 22 respectively.

[0039] like Figure 8As shown, a system for controlling an automatic window closing device that combines rain detection and weather forecasting includes a central controller. The central controller reads data from a light sensor 29 and a rain sensor 28, and performs data analysis to precisely control a shading motor 22 and a window opening / closing motor 20. The system also includes a rain sensor 28 and a light sensor 29, which determine the amount of rainfall or light intensity in the external environment. The system further includes a shading motor 22 and a window opening / closing motor 20, which respectively perform shading and window opening / closing operations. A motor drive module amplifies the weak electrical signal from the central controller and converts it into current and voltage sufficient to drive the shading motor 22 and the window opening / closing motor 20. Finally, a communication module and a control terminal are included. The communication module is used to implement… The system includes remote control and data viewing, as well as network connectivity via a communication module. It can import weather forecasts. Considering the inaccuracy of weather forecasts and the inherent lag in using only the rain sensor 28, it can be configured to control both the weather forecast and the rain sensor 28. For example, windows can be closed ten minutes before the forecast. If the rain sensor reading does not increase within a certain time after the forecast's scheduled time, the windows are opened; otherwise, they remain closed. The rain sensor's control authority is greater than that of the weather forecast data. The window is closed when the rain sensor reaches a set threshold. The control terminal is an external control device. Sensor data can be viewed at any time via a mobile app or mini-program, and windows can be manually opened / closed or shaded remotely. The system also includes a power module to provide stable voltage and current to the central controller, sensors, and two motors.

[0040] The specific implementation process is as follows: The device of the present invention can control the window opening and closing motor 20 and the light-blocking motor 22 through the control terminal, enabling remote opening and closing of windows and light blocking. At the same time, the window opening and closing motor 20 and the light-blocking motor 22 can also be automatically controlled by the rain sensor 28 and the light sensor 29 to open and close windows and block light. The threshold values ​​of the rain sensor 28 and the light sensor 29 can be preset through the control terminal. When the threshold value is greater than a certain value, the window is closed, and when the threshold value is less than a certain value, the window is opened.

[0041] The device of this invention can remotely control the opening and closing of windows and the operation of shading via a control terminal. When the shading motor 22 is started, it drives the spline shafts 23 on both sides to rotate. The rotation of the spline shafts 23 drives the rotating shaft 25 to rotate, and the shading curtain 27 connected to and surrounding the rotating shaft 25 will rise or fall, thereby opening or closing the shading curtain 27. When the window opening and closing motor 20 is started, its window opening and closing process has been described in detail above. The window can be opened or closed by starting the window opening and closing motor 20.

[0042] The device of the present invention can control the opening and closing of windows and the shading operation through the rain sensor 28 and the light sensor 29. The upper and lower thresholds of the rain sensor 28 and the light sensor 29 can be preset through the control terminal. That is, when the threshold exceeds a certain value, the window opening and shading process is performed, and when the threshold is lower than a certain value, the window closing and the shading curtain 27 is opened.

[0043] The above descriptions are merely embodiments of the present invention, and common technical solutions or characteristics known in the schemes are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
