Description

Technical Field

[0001] This utility model relates to the field of intelligent building equipment technology, and in particular to a noise-reducing window closing device applied to intelligent building systems. Background Technology

[0002] With the acceleration of urbanization, urban noise pollution is becoming increasingly serious. As an important development direction in modern architecture, intelligent buildings place higher demands on the comfort and quietness of living and working environments. Currently, most windows in intelligent buildings only have simple opening and closing functions and cannot automatically close according to external noise levels. When external noise is high, users need to manually close the windows, which is inconvenient and cannot effectively block noise in a timely manner, affecting the quality of the indoor environment.

[0003] The prior art can be referenced in Chinese Patent No. CN202125145U, which discloses a noise-sensing window closing device for use in intelligent building systems. The device includes a noise sensing device for sensing noise decibels and a window closing device for controlling the closing of windows. The output end of the noise sensing device is connected to the input end of the window closing device. This noise-sensing window closing device realizes noise detection and window closing. However, after the window is closed, there will be gaps, and noise will be transmitted into the room through the gaps, resulting in poor sound insulation. Therefore, a noise-sensing window closing device for use in intelligent building systems is provided here. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a noise-controlled window closing device for intelligent building systems. Through the coordinated use of a drive motor, rack and pinion, noise sensor, and controller, it monitors external noise and automatically closes the window when the noise is too loud.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-5 A noise-reducing window closing device for use in intelligent building systems includes an outer fixed frame 1, a window frame 3 on the inner wall of the outer fixed frame 1, a fixed window sash 4 on one side inside the window frame 3, a movable window sash 5 on the other side inside the window frame 3, a drive motor 8 on the bottom of the outer wall of one side of the fixed window sash 4, a gear 10 connected to the output end of the drive motor 8, a rack 9 fixed to the bottom of the inner wall of the movable window sash 5, the gear 10 meshing with the rack 9, and a sound insulation component fixed to the inner wall of the side of the window frame 3 facing the interior.

[0023] The two vertical outer walls of the movable window sash 5 that contact the window frame 3 are equipped with buffer strips. The buffer strips can reduce the impact force generated when opening and closing the window and reduce the noise when opening and closing the window.

[0024] A noise sensor 2 is fixed to the top of the side of the window frame 3 facing the outside, and a controller 6 is fixed to the top of the side of the window frame 3 facing the inside. Both the noise sensor 2 and the controller 6 are electrically connected.

[0025] Limit switches 12 are fixed on the inner walls of opposite sides of the window frame 3, and limit blocks 11 are fixed at both ends of the top of the outer side of the movable window sash 5. The limit switches 12 are electrically connected to the controller 6.

[0026] The noise sensor 2 monitors external noise in real time and transmits the received sound wave signal to the controller 6. The controller 6 processes the signal, and when the noise intensity is too high, the controller 6 sends a control signal to the drive motor 8. The drive motor 8 drives the gear 10 to rotate, and the gear 10 drives the rack 9 and the movable window sash 5 to move, so as to realize automatic window closing. When the movable window sash 5 moves to the limit position, the limit block 11 triggers the limit switch 12. The limit switch 12 feeds back the signal to the controller 6 to control the drive motor 8 to stop working, so as to prevent the movable window sash 5 from being damaged due to excessive movement.

[0027] Example 2 is an optimization based on Example 1. Specifically, the sound insulation component includes an annular airbag 7 fixed to the inner wall of the window frame 3 facing the interior. An air nozzle 15 is provided on the annular airbag 7. A miniature silent air pump 13 is installed on the inner wall of the fixed window sash 4. The air outlet of the miniature silent air pump 13 is connected to an inflation pipe 14. One end of the inflation pipe 14 is connected to the air nozzle 15. The miniature silent air pump 13 is electrically connected to the controller 6.

[0028] When the movable window sash 5 is closed, the controller 6 sends a control signal to the miniature silent air pump 13. The miniature silent air pump 13 inflates the annular airbag 7 for a certain period of time. The annular airbag 7 blocks the gaps at the edge of the window frame 3, thereby further blocking noise and improving the quality of the living and working environment in the smart building. It has good practicality and promotional value.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
