Description

Technical Field

[0001] The present invention relates to the technical field of building doors and windows, and specifically discloses an intelligent outward-opening system window with remote control of the opening and closing angle. Background Art

[0002] With the continuous development of the Internet of Things, cloud computing, and mobile Internet, and the continuous improvement of consumer demand, smart communities and smart homes have gradually come into people's view. As the main transparent enclosure component of buildings, the door and window system plays an increasingly obvious role in the development of smart homes. At present, there are already some system windows on the market that can remotely control the opening and closing of window sashes according to the weather. They mainly use rain sensors to detect whether it is raining outside, and then the controller controls the operation of the driving device according to the detected signal to achieve the closing of the doors and windows.

[0003] For example, the invention patent with the application number 202011145133X discloses an intelligent door and window with a wind and rain sensing system, including a profile tube 1, a profile tube 2, a rain sensor, a wind speed sensor, a driving motor, a control box, a glass installation frame, and a glass sheet. Two profile tubes 1 and two profile tubes 2 are connected to form a rectangular frame. On the left and right sides of the profile tube 1, a pair of rotatable L-shaped mounting strips 1 are symmetrically arranged. In the middle of each pair of mounting strips 1, there is a rotatable mounting strip 2. The mounting strip 2 is connected to the inner mounting strip 1 by a rivet. The rain sensor is installed on the lower mounting strip 2, and the wind speed sensor is installed on the upper mounting strip 2. The driving motor drives the mounting strip 1 to rotate through a belt drive. The glass sheet is inlaid in the glass installation frame, and the glass installation frame is connected to the mounting strip 1. This invention uses sensors to detect the outdoor environment, and then controls the automatic closing of the doors and windows through the driving motor, making the doors and windows have a certain degree of intelligence. However, the degree of intelligence of the intelligent door and window disclosed in this invention patent is still low. When the user goes out, they cannot obtain the current opening and closing angle of the doors and windows in real time, and in different weather conditions, the user cannot open the doors and windows to the opening and closing angle they need according to their own needs. Therefore, in view of the above deficiencies of the existing intelligent door and window with a wind and rain sensing system, the present invention proposes an intelligent outward-opening system window with remote control of the opening and closing angle that can effectively solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent outward-opening system window that can remotely control the opening and closing angle to solve the deficiencies of the existing intelligent doors and windows that cannot obtain the current opening and closing angle information of the doors and windows and cannot accurately control the opening and closing angle of the doors and windows.

[0005] The present invention is achieved through the following technical solutions:

[0006] An intelligent outward-opening system window with remote control of the opening and closing angle includes a window frame, a window sash, glass, a control processing device, and a remote terminal. The window sash is rotatably connected to the window frame. A driving device for adjusting the opening and closing angle of the window sash is provided on the window frame. The driving device is electrically connected to the control processing device. The remote terminal is wirelessly connected to the control processing device. A cavity is formed on the window frame. A sliding rheostat and a current sensor are arranged in the cavity. A detection circuit is arranged between the sliding rheostat and the current sensor, and the current sensor is electrically connected to the control processing device.

[0007] A strip-shaped sliding opening communicating with the cavity and aligned with the sliding rheostat is formed on the window frame. A slide rail parallel to the strip-shaped sliding opening is arranged on the window frame. A slider is arranged on the slide rail. An insulating connecting block passing through the strip-shaped sliding opening and connected to the sliding piece on the sliding rheostat is arranged at the lower end of the slider. A rotating support bar is connected to the upper end of the slider. The end of the rotating support bar is rotatably connected to the window sash.

[0008] When designing the intelligent outward-opening system window disclosed in the present invention, due to different opening and closing angles of the window sash, the position of the slider connected by the rotating support bar on the slide rail is also different. A detection circuit is arranged in the inner cavity of the window frame. The slider is connected to the sliding piece on the sliding rheostat in the detection circuit. Then, by transmitting the current acquisition signal of the current sensor in the detection circuit to the control processing device for conversion, the specific opening and closing angle of the window sash can be obtained. Then, the converted opening and closing angle signal is wirelessly transmitted to the remote terminal, so that the user can accurately obtain the opening and closing angle of the current door and window.

[0009] In addition, when the user needs to remotely control the opening and closing angle of the window sash, only need to send a control signal through the remote terminal, and then the control processing device can control the driving device to make the window sash rotate. During the process of the window sash rotating to adjust the opening and closing angle, the changing current signal can also be obtained in real time through the detection circuit, and then converted into the corresponding opening and closing angle signal. When the set opening and closing angle signal is obtained, the control processing device will immediately turn off the driving device, so that the opening and closing angle position of the window sash is maintained at the position required by the user.

[0010] As a specific setting of the above solution, the control processing device includes a control box. A control module, a signal conversion module, and a wireless transmission module are arranged inside the control box. The driving device is connected to the control module. The remote terminal is connected to the wireless transmission module. The current sensor is connected to the signal conversion module.

[0011] As a further setting of the above solution, a wind speed sensor and a rain sensor are also provided on the outer side of the window frame, and both the wind speed sensor and the rain sensor are electrically connected to the control module in the control processing device. Through the wind speed sensor and the rain sensor, the external environmental conditions can be obtained in real time, and in special cases, the window sash will be self-checked for closing by detecting the current first. If it is found that the window sash is not closed, a reminder message will be sent to the remote terminal, or the driving device will be controlled automatically to close the window sash.

[0012] As a further setting of the above solution, a strip-shaped storage groove is opened at the upper end of the strip-shaped sliding opening. The bottom wall of the strip-shaped storage groove is connected with a toothed strip through a spring, and a strip-shaped opening aligned with the strip-shaped sliding opening is opened on the toothed strip. A engaging surface matching the toothed strip is provided on the slider. A magnetic adsorption block is also provided on the toothed strip. An electromagnet aligned with the magnetic adsorption block is provided in the strip-shaped storage groove, and the electromagnet is electrically connected to the control processing device. Through the action of the spring and the electromagnet, the toothed strip is actively lifted and lowered in the strip-shaped storage groove, and then the slider is fixed through the engagement between the engaging surface on the slider and the toothed strip. After the opening and closing angle of the window sash is adjusted, the fixing of the slider is used to ensure that the window sash will not rotate under the influence of wind force.

[0013] As a specific setting of the above solution, a rotating rod rotatably connected to the window frame is provided on the window sash. The driving device includes a driving motor provided on the window frame. A first bevel gear is connected to the motor shaft of the driving motor, and a second bevel gear meshing with the first bevel gear is connected to the end of the rotating rod.

[0014] As a specific setting of the above solution, the detection circuit includes a power supply, a circuit switch controller, a current sensor, a sliding rheostat, and a protection resistor connected in series.

[0015] As a specific setting of the above solution, the window frame includes a main window frame and an independent window frame. The independent window frame is fixedly arranged in the installation opening on the main window frame, and the window sash is rotatably connected in the independent window frame.

[0016] As a further setting of the above solution, a window lock is also provided on the window sash, and the closing end of the window sash is fixed in the independent window frame through the window lock.

[0017] The present invention has the following beneficial effects:

[0018] The intelligent outward-opening system window disclosed by the present invention utilizes the principle that the movement of the window sash during outward rotation drives the slider to move along the slide rail. A sliding rheostat is arranged inside the window frame, and the sliding piece on the sliding rheostat is connected to the slider. Then, a detection circuit is connected in series at both ends of the sliding rheostat. The current sensor in the detection circuit is used to obtain the electrical signal in real time, and the electrical signal is converted into the opening and closing angle signal of the window sash. Then, the opening and closing angle signal is wirelessly transmitted to the remote terminal, enabling the user to remotely obtain the opening and closing angle of the window sash. At the same time, the window sash can be remotely controlled to rotate, and during the rotation of the window sash, the real-time opening and closing angle signal is converted through the electrical signal of the current sensor, so that the opening and closing angle can be accurately controlled. The entire intelligent outward-opening system window has a high degree of intelligence, effectively solving the deficiencies of existing intelligent doors and windows that cannot obtain the current opening and closing angle information of the doors and windows and cannot remotely and accurately control the opening and closing angle of the doors and windows.

[0019] The present invention further improves the structure between the window frame and the window sash, and actively realizes the engagement and separation between the toothed strip and the engaging surface on the slider through the action of the spring and the electromagnet. When it is necessary to remotely control the window sash to adjust the opening and closing angle, the toothed strip can be retracted to achieve separation from the engaging surface on the slider, and then the rotation adjustment of the window sash can be carried out. After the opening and closing angle of the window sash is adjusted, the slider can be engaged and fixed on the toothed strip to ensure the connection stability after the angle adjustment of the window sash and ensure that it is not affected by external wind force.

[0020] The present invention further sets a wind speed sensor and a rain sensor to obtain the external environmental conditions in real time, so as to realize the functions of remote alarm and active window closing, preventing unnecessary impacts on the interior of the house due to the window not being closed in rainy or windy weather.

[0031] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0032] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 - 9 drawings and describe this application in detail in conjunction with the embodiments. Embodiment

[0033] Embodiment 1 discloses an intelligent outward-opening system window that can remotely control the opening and closing angle. Referring to the attached Figure 1 and the attached Figure 2 drawings, it includes a general window frame 1, an independent window frame 2, a window sash 3, glass 4, and a window lock 5. The glass 4 is installed in the general window frame 1 and the window sash 3 according to size requirements. The independent window frame 2 is fixedly installed in the installation opening of the general window frame 1, and the window sash 3 is rotatably connected to the independent window frame 2. Then, the window lock 5 is set on the window sash 3 so that it can be closed and locked with the independent window frame 2.

[0034] Referring to the attached Figure 2 and the attached Figure 4, a control processing device is fixedly installed at the lower end of the side of the independent window frame 2. The control processing device includes a control box 100. Inside the control box 100, a control module, a signal conversion module, and a wireless transmission module are provided. Specifically, the control module, the signal conversion module, and the wireless transmission module are prior arts, and can be selected according to requirements, and will not be described in detail here.

[0035] A rotating rod 6 is provided at one end of the window sash 3, and the upper and lower ends of the rotating rod 6 are rotatably connected to the upper and lower ends of the independent window frame 2. At the same time, a driving device for driving the rotating rod 6 to rotate is provided at the lower end of the independent window frame 2. Specifically, the driving device includes a driving motor 7 provided in the independent window frame 2. The driving motor 7 is electrically connected to the control module and is controlled by the signal of the control module. At the same time, a first bevel gear is connected to the motor shaft of the driving motor 7, and then a second bevel gear 8 meshing with the first bevel gear is connected to the lower end of the rotating rod 6. When it is necessary to control the opening or closing of the window sash 3, it can be manually operated, or a control instruction can be sent through the control module, and then the driving motor 7 rotates forward or backward, and the rotation of the window sash 3 can be realized through the meshing transmission of the second bevel gear 8 and the first bevel gear.

[0036] Refer to the appendix Figure 6 , a cavity 201 is opened at the lower end of the independent window frame 2. A sliding rheostat 9 and a current sensor 12 are fixedly provided inside the cavity, and a detection circuit is provided between the sliding rheostat 9 and the current sensor 12. Specifically, the detection circuit refers to the appendix Figure 8 , a power supply 10, a circuit switch controller 11, and a protection resistor (not shown in the figure) are also connected in series in the detection circuit, and then the signal output end of the current sensor 12 is connected to the signal conversion module inside the control box 100.

[0037] Refer to the appendix Figure 4 , appendix Figure 5 and appendix Figure 6, the independent window frame 2 located directly above the sliding rheostat 9 is provided with a strip-shaped sliding opening 202. A strip-shaped storage groove 203 is provided at the upper end of the strip-shaped sliding opening 202, and a number of springs 13 are connected to the bottom wall of the strip-shaped storage groove 203. Then, a toothed strip 14 is commonly connected to the upper ends of the number of springs 13. At the same time, a strip-shaped opening 141 aligned with the strip-shaped sliding opening 202 is provided on the toothed strip 14. Electromagnets 15 are arranged at the left and right ends of the strip-shaped storage groove 203, and the electromagnets 15 are also electrically connected to the control module in the control box 100, so that the energization of the electromagnet 15 circuit is controlled by the signal of the control module. Then, magnetic adsorption blocks 16 aligned with the electromagnets 15 are arranged at the left and right ends of the toothed strip 14. When the electromagnets 15 are not energized, the upper end of the toothed strip 14 extends out of the strip-shaped storage groove 203 due to the support of the number of springs 13; when the electromagnets 15 are energized, since the electromagnets 15 have an adsorption effect on the magnetic adsorption blocks 16, the toothed strip 14 overcomes the acting force of the springs 13 and retracts into the strip-shaped storage groove 203.

[0038] On the independent window frame 2 on the front and rear sides of the strip-shaped storage groove 203, slide rails 17 parallel to the toothed strip 14 are fixedly connected, and sliders 18 that can move left and right are arranged on the two slide rails 17. At the same time, a engaging surface matching the toothed strip 14 is provided on the lower surface of the slider 18. When the toothed strip 14 is pushed out of the strip-shaped storage groove 203 by the action of the springs 13, it is engaged with the engaging surface on the slider 18, thereby realizing the fixation of the slider 18. Then, an insulating connection block 19 is connected to the lower surface of the slider 18. The lower end of the insulating connection block 19 passes through the strip-shaped opening 141 on the toothed strip 14 and the strip-shaped sliding opening 202 on the independent window frame 2 and extends into the cavity 201, and the lower end of the insulating connection block 19 is connected to the sliding piece on the sliding rheostat 9. Finally, a rotating support bar 20 is connected to the upper surface of the slider 18 through a pin shaft, and the movable end of the rotating support bar 20 is rotatably connected to the inner side surface of the window sash 3.

[0039] Reference appendix Figure 9 , the intelligent outward-turning system window disclosed in this Embodiment 1 further includes a remote terminal wirelessly connected to the control box 100. Specifically, the remote terminal can be a common smart phone. When the user goes out and wants to know whether the window sash 3 in the intelligent outward-turning system window at home is open and the specific opening and closing angle, a signal can be sent to the control box 100 through the remote terminal. Then, the control module inside the control box 100 will close the circuit switch controller 11 in the detection circuit, so that the detection circuit is connected. Then, the current sensor 12 detects the magnitude of the current in the circuit, and the detected current value is fed back to the signal conversion module to convert and obtain the opening and closing angle of the window sash 3. Finally, the converted result is transmitted to the remote terminal by the wireless transmission module in the control box 100 for the user to check.

[0040] When the user wants to remotely control the opening and closing of the window sash 3 and its opening and closing angle, a command is directly sent through the remote terminal. When the control box 100 receives the signal, it will generate a corresponding command signal. First, it controls the circuit of the electromagnet 15 to be connected, so that it generates a downward adsorption force on the magnetic adsorption block 16. Under the action of the adsorption force, the toothed strip 14 is received into the strip-shaped storage groove 203. Therefore, the toothed strip 14 is separated from the engaging surface on the slider 18. At this time, the slider 18 can move left and right along the slide rail 17.

[0041] Then, it controls the driving motor 7 to rotate. Under the action of the driving motor 7, the window sash 3 starts to rotate to adjust the opening and closing angle. At the same time, during the adjustment of the opening and closing angle of the window sash 3, the rotating support bar 20 will rotate, and then the slider 18 moves along the slide rail 17. During the movement of the slider 18, it will drive the slide of the sliding rheostat 9, thereby changing the resistance in the detection circuit and performing real-time feedback through the current sensor 12. When the converted signal after the feedback of the current sensor 12 is the same as the signal sent by the remote terminal, at this time, the control module will turn off the driving motor 7 and the electromagnet 15. Then, the toothed strip 14 moves upward under the action of the spring 13 and is clamped and fixed with the engaging surface on the slider 18 to prevent the window sash 3 from rotating under the influence of wind. At this time, the adjustment process of the entire window sash opening and closing angle is completed. Embodiment

[0042] Embodiment 2 discloses an intelligent outward-turning system window which is further improved based on Embodiment 1. The same parts as those in Embodiment 1 will not be described again. The differences are referred to in the attached Figure 7 and the attached Figure 9 .

[0043] In this Embodiment 2, a wind speed sensor 21 and a rain sensor 22 are also provided at the upper end of the outer side surface of the independent window frame 2. Specifically, the wind speed sensor 21 and the rain sensor 22 can also be provided on the outer side surface of the total window frame 1. Then, both the wind speed sensor 21 and the rain sensor 22 are electrically connected to the control module inside the control box 100.

[0044] The intelligent outward-turning system window disclosed in this Embodiment 2 also monitors the weather conditions through the wind speed sensor 21 and the rain sensor 22. When the rain sensor 22 detects that it starts to rain or the wind speed sensor 21 detects that the wind force is large, the control module will first confirm whether the window sash 3 is in the closed state through the detection circuit. If the window sash 3 is not in the closed state, the control module will send a reminder message to the remote terminal through the wireless transmission module and wait for the user to feedback the closing signal. If the user does not feedback the closing signal for a long time, when the rain sensor 22 detects that the external rainfall is large or the wind force is large, the control module will actively control the driving motor 7 and the electromagnet 15 to achieve the active closing of the window sash 3, so as to avoid unnecessary impacts on the interior of the house due to the unclosed window in rainy and windy weather.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
