[0021] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0022] Reference Figure 1 , Figure 1 The following is a schematic diagram of a structural block diagram of a specific embodiment of the automatic window closing device 1 of the utility model. In the embodiment shown in the figure, the automatic window closing device 1 includes a rain sensor 11, a supporting cylinder 12, a window closing detection component and a controller 13. As is known to all, at present, most windows such as Figure 2 As shown, the window frame 10 is mounted on the wall and the window sash 20 is hingedly connected to the window frame 10 by a hinge 30. Figure 3 As shown, the rain sensor 11 in the utility model is arranged on the outside of the window sash 20 to detect whether it is raining and obtain precipitation information; in this embodiment, a groove 203 is provided at the lower end of the outer surface of the frame body of the window sash 20, and the rain sensor 11 is located in the groove 203; and the number of the supporting cylinder 12 is one, one end of the supporting cylinder 12 is rotatably connected to the window frame 10, and the other end is rotatably connected to the window sash 20; the window closing detection component includes an acceleration sensor 14 and a reflection sensor 15, and the acceleration sensor 14 is arranged on the window sash 20. In order to detect the movement of the window sash 20, the reflective sensor 15 is arranged on the side of the window sash 20 opposite to the window frame 10, and is used to detect whether the window sash 20 is closed; the controller 13 is connected to the rain sensor 11, the supporting cylinder 12, the acceleration sensor 14 and the reflective sensor 15, and is used to control the support cylinder 12 to work according to the precipitation information detected by the rain sensor 11, and at the same time control the reflective sensor 15 and the supporting cylinder 12 to work according to the detection information of the acceleration sensor 14; preferably, the controller 13 can be implemented by a single-chip microcomputer, ARM or DSP. Based on the above design, when the window sash 20 is opened, the supporting cylinder 12 extends to support the window sash 20, and when the rain sensor 11 detects rain, the controller 13 controls the supporting cylinder 12 to retract to achieve automatic window closing, and after starting the window closing, the acceleration sensor 14 works to detect whether the window sash 20 is in a moving state or a stationary state, and wakes up the reflective sensor 15 through the controller 13 when the window sash 20 is in a stationary state, and can detect whether the window is closed based on the reflected information, and the automatic window closing ends when the window is closed, and when the window is not closed, the controller 13 controls the supporting cylinder 12 to retract again to close the window tightly to avoid the situation where the window is not completely closed automatically on rainy days.

[0023] In some embodiments, the supporting cylinder 12 includes a piston cylinder 121 and a piston rod 122 connected to the piston cylinder 121. In this embodiment, the number of the supporting cylinder 12 is one, which is located in the middle of the window frame 10. The piston cylinder 121 is rotatably connected to the window frame 10, and the piston rod 122 is rotatably connected to the middle and lower part of the window sash 20. Specifically, the piston cylinder 121 and the piston rod 122 are also connected to a first rotating cylinder 1211 and a second rotating cylinder 1221, respectively. A first rotating shaft 102 is fixed to the bottom of the window frame 10 through a fixing plate 101. The first rotating cylinder 1211 is sleeved on the first rotating shaft 102 and can rotate around the first rotating shaft 102. A fixed wing 201 is provided in the middle of the window sash 20. A second rotating shaft 202 is connected to the fixed wing 201. The second rotating cylinder 1221 is sleeved on the second rotating shaft 202 and can rotate around the second rotating shaft 202. It is understandable that in some other embodiments, the number of the supporting cylinders 12 can also be set to two, and the two supporting cylinders 12 can be respectively located on both sides of the window frame 10 of a window, and one end of each supporting cylinder 12 can be rotatably connected to the window frame 10, and the other end can be rotatably connected to the middle and lower part of one side of the window sash 20. Based on the above design, under the control of the controller 13, the piston rod 122 can be extended or retracted, and during the retraction process, the piston rod 122 and the piston cylinder 121 can rotate around the second rotating shaft 202 and the first rotating shaft 102 respectively, so as to achieve the closing of the window sash 20. It is understandable that in some other embodiments, the piston cylinder 121 can be rotatably connected to the window sash 20, and accordingly, the piston rod 122 can be rotatably connected to the window frame 10, and can also support the window, and can also achieve the closing and retraction of the window under the action of the controller 13.

[0024] Preferably, in this embodiment, the reflective sensor 15 includes an infrared distance detection sensor to determine whether the window is closed by measuring the side reflection principle, that is, the infrared wave is reflected by an obstacle, and the infrared distance detection sensor receiving end receives the reflected wave to detect whether the window sash 20 is closed, or the window gap reflection distance is measured according to the reflected wave to detect whether the window sash 20 is closed. It is understandable that in some other embodiments, the reflective sensor 15 can also be a radar detection sensor, which can also detect whether the window sash 20 is closed, that is, the radar detection wave is reflected by an obstacle, and if the reflected wave is received, it is determined that the window sash 20 is closed, or the measured window gap is less than a preset threshold, it is determined that the window sash 20 is closed.

[0025] Furthermore, the automatic window closing device 1 may also include a power supply 16 and a controllable power switch 17. The power supply 16 supplies power to each module of the automatic window closing device 1 (controller 13, rain sensor 11, acceleration sensor 14, etc.), and the power supply 16 is connected to the reflective sensor 15 through a controllable power switch 17. The controller 13 is connected to the controllable power switch 17 to control the opening and closing of the controllable power switch 17 according to the detection information from the acceleration sensor 14, thereby controlling the operation of the reflective sensor 15. Based on this design, the reflective sensor 15 can be in a power-off state at ordinary times and does not need to consume power.

[0026] In some embodiments, the acceleration sensor 14 includes an axial acceleration sensor, a centrifugal acceleration sensor and / or a vibration sensor to identify movement or vibration of the window sash 20 .

[0027] It can be understood that when the automatic window closing device 1 of the utility model is used, the rain sensor 11 arranged on the outer surface of the window sash 20 detects whether it is raining. When it is detected that it is raining, the controller 13 controls the support cylinder 12 to retract, so as to realize automatic window closing. After the controller 13 sends a command to the support cylinder 12 to make the support cylinder 12 retract, the controller 13 controls the acceleration sensor 14 to work. If the acceleration of the acceleration sensor 14 is less than the set threshold value, it is considered that the window sash 20 is in a stationary state. At this time, the controller 13 wakes up the reflective sensor 15 to work, and the reflective sensor 15 is activated. When working, it will judge whether the gap distance between the window sash 20 and the window frame 10 is greater than the preset distance (or judge whether there is a reflection signal) for multiple times within the specified time. If the gap distance is greater than the preset distance (or there is no reflection), it is judged that the window sash 20 is in the open state, and the controller 13 controls the supporting cylinder 12 to retract again to close the window tightly, so as to avoid the situation that the window is not completely closed automatically on rainy days; and if it is judged that the reflective sensor 15 has a reflection signal (or the gap distance is less than or equal to the preset distance) for multiple times within the specified time, it is considered that the window sash 20 is in the closed state, and the automatic window closing process ends.

[0028] In summary, the automatic window closing device of the utility model can realize automatic window closing and avoid the situation that the window is not completely closed automatically on rainy days, thereby further improving the user experience.

[0029] The above-mentioned preferred implementation modes should be regarded as examples of the implementation modes of the utility model scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the utility model scheme or made based on it should be regarded as within the scope of protection of this patent.
