Description

Technical Field

[0001] The invention relates to the technical field of building doors and windows, and particularly discloses an intelligent window which automatically closes due to rain gravity induction. Background Art

[0002] Most buildings are equipped with system windows to increase indoor light intensity and to open them for ventilation when the weather is fine. Currently, most windows on the market are closed or opened manually, which results in rainwater falling into the house when no one is home and causing inconvenience to people's lives.

[0003] Utility model patent application number 2021210592699 discloses an intelligent, inductive, rainproof flip-up window. The window frame comprises a window body pivotally connected to the top of the window frame, and a drive mechanism for rotating the window body. The drive mechanism comprises a drive rod hinged at one end to the side wall of the window body, a drive member connected to the window frame, and a drive member slidably connected to the window frame at the end of the drive rod facing away from the window body. The drive member is used to drive the drive rod to slide at the end facing away from the window body. A rain sensor is also provided on the outside of the window, electrically connected to the drive member via a control system. Rain shields are provided on both sides of the window body. While the flip-up window disclosed in this patent provides rainproofing, its overall structure is relatively complex. It requires the addition of a rain sensor and a drive mechanism to an existing system window, which not only increases the manufacturing cost of the entire system window, but also requires connecting the rain sensor and drive mechanism to the home's electrical circuit during installation. Since typical housing designs do not include corresponding circuits near windows, external wiring is required to connect the rain sensor and drive mechanism to the home's electrical circuit, making the overall installation very cumbersome and complex. In response to the above-mentioned shortcomings of the existing intelligent sensing rainproof flip-up windows, this application designs a system window that can use the gravity of collected rainwater to automatically close the windows, thereby solving the technical problems existing in the actual application of the existing technology. Summary of the Invention

[0004] The present invention aims to provide a smart window that can automatically close the window by utilizing the gravity of collected rainwater, so as to solve the shortcomings of existing rainproof windows that have complex structures and require external circuits to realize window closing.

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

[0006] An intelligent window with automatic window closing by rain gravity induction, comprising a window frame, a window sash, glass and a window lock. The window sash is rotatably connected to the upper end of the window frame. A water accumulation groove is arranged at the lower end of the outer surface of the window sash. Vertical sliding rails are arranged on both side walls of the window frame, and clamping grooves are formed on the sliding rails. A sliding seat is arranged on each sliding rail. A pawl tooth matching the clamping groove is rotatably connected to the sliding seat through a first torsion spring, and a trigger bar is arranged at the outer end of the pin shaft of the pawl tooth.

[0007] A bent connecting rod assembly is arranged between the window sash and the sliding seat. The bent connecting rod assembly includes a first connecting rod rotatably connected to the window sash. The end of the first connecting rod is rotatably connected to a second connecting rod through a second torsion spring. A rotating pin connected to the sliding seat is arranged on the second connecting rod. A lever for acting on the trigger bar and disengaging the pawl tooth from the clamping groove is connected to the movable end of the second connecting rod.

[0008] As a specific setting of the above solution, a connecting side plate is arranged on the side of the sliding seat facing the interior. The pawl tooth is rotatably connected to the connecting side plate through a pin shaft. A limiting notch for passing through the pawl tooth is formed on the sliding seat.

[0009] As a specific setting of the above solution, the rotating pin is connected at a position close to the movable end of the second connecting rod.

[0010] As a further setting of the above solution, the bottom of the water accumulation groove is flat, and a drainage hole is formed at the bottom of the water accumulation groove. A pulling groove is further formed inside the bottom wall of the water accumulation groove. A partition for blocking the drainage hole is movably arranged in the pulling groove, and a through hole corresponding to the drainage hole is formed on the partition. The through hole is misaligned with the drainage hole when the partition is not subjected to external force.

[0011] As a further setting of the above solution, a connecting strip extending out of the lower end of the window sash is connected to the side end of the partition. A buffer anti-collision block is connected to the outer end of the connecting strip. A spring is arranged between the buffer anti-collision block and the window sash. A convex plate corresponding to the buffer anti-collision block is arranged on the bottom wall of the window frame.

[0012] As a further setting of the above solution, a storage groove adapted to the buffer anti-collision block is formed at the lower end of the window sash. One end of the spring is connected to the buffer anti-collision block, and the other end is connected to the inner wall of the storage groove.

[0013] As a further setting of the above solution, a magnetic adsorption strip is arranged on the outer side surface of the convex plate. A metal adsorption sheet acting on the magnetic adsorption strip is arranged at the lower end of the window sash.

[0014] When the intelligent window with rain gravity induction and automatic window closing provided by the present invention encounters rainy weather when the window sash is open, the water collecting trough is used to collect the rainwater falling on the window sash and glass, so that the gravity at the lower end of the window sash increases. During the process of the force at the lower end of the window sash gradually increasing, the first connecting rod and the second connecting rod in the bending connecting rod assembly will bend against the acting force of the second torsion spring. At this time, the originally linear bending connecting rod assembly will change to a V-shaped structure, and then the movable end of the second connecting rod will rotate upward. When the movable end of the second connecting rod rotates upward, it will act on the trigger strip at the outer end of the pawl tooth through the lever, so that the pawl tooth on the sliding seat is disengaged from the card slot on the slide rail.

[0015] Once the pawl tooth is disengaged from the card slot, its sliding seat will instantaneously move downward along the slide rail. At this time, the supporting force of the bending connecting rod assembly on the window sash disappears, and then the window sash rotates downward under its own gravity and the gravity of the rainwater and closes in the window frame, which can effectively prevent rainwater from entering the room.

[0016] In addition, during the process of the window sash rotating downward and closing, the buffer anti-collision block, spring and convex plate can be used to buffer its rotation process, reduce the impact force when the window sash closes on the window frame, and at the same time, the partition in the draw groove can be moved, so that the through hole on the partition is aligned with the drain hole on the water collecting trough, and then the rainwater in the water collecting trough is discharged.

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

[0018] The intelligent window with rain gravity induction and automatic window closing disclosed by the present invention has a simple structural design. By using components such as the designed bending connecting rod assembly, sliding seat, pawl tooth, and slide rail, when the rainwater in the water collecting trough reaches a certain amount, the trigger strip on the pawl tooth can be triggered, so that the pawl tooth is disengaged from the card slot on the slide rail, thereby making the supporting force acting on the window sash disappear, and then the window sash can quickly close in the window frame under the action of gravity; compared with the prior art, the entire intelligent window only replaces the supporting hinge in the existing window with the above components, and the overall structural design is simple. Without external circuit power supply, it also achieves a good rain prevention effect.

[0019] The present invention further improves the design of the action of rain gravity induction and automatic window closing. It can not only effectively prevent the impact force generated by the window sash closing due to gravity on the entire intelligent window, but also automatically drain the rainwater in the water collecting trough after the window sash closes; in addition, through the magnetic adsorption between the window sash and the window frame, the window sash can be tightly closed in the window frame to prevent rainwater from entering the room through the gap, further improving the rain prevention effect of the entire intelligent window.

[0030] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0031] It should be noted that, without conflict, the embodiments in the present 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 the present application in detail in conjunction with the embodiments. Embodiment

[0032] Embodiment 1 discloses an intelligent window with automatic closing by rain gravity sensing. Refer to Appendix Figure 1 and Appendix Figure 2 . The main body of the intelligent window includes a window frame 1, a window sash 2, glass 3 and a window lock 4. The window frame 1 is fixedly installed in the window reserved in the building, and the glass 3 is installed in the window sash 2. The upper end of the window sash 2 is rotatably connected to the window frame 1 through a hinge 5, and the window lock 4 is arranged inside the lower end of the window sash 2, thus forming an upward-opening intelligent window. When the window sash 2 needs to be opened, it only needs to be pushed outwards.

[0033] Refer to Appendix Figure 1 and Appendix Figure 3 . A water collecting groove 6 is arranged on the outer side surface of the lower end of the window sash 2. In this Embodiment 1, the cross-section of the water collecting groove 6 is fan-shaped. When rainwater falls on the outer surfaces of the window sash 2 and the glass 3, the rainwater can flow down into the water collecting groove 6 for storage. Vertical slide rails 7 are fixedly installed on the inner walls of the left and right sides of the window frame 1, and a clamping groove 701 is opened on the inner side surface of the slide rail 7 facing inwards. Specifically, several clamping grooves 701 can be designed according to actual situations, so that the opening angle of the window sash 2 has multiple controllable gears.

[0034] Refer to Appendix Figure 4 , Appendix Figure 5 and Appendix Figure 6 . A sliding seat 8 matching with the slide rail 7 is arranged on the slide rail 7, and two parallel connecting side plates 801 are arranged on the inner side surface of the sliding seat 8 facing inwards. Then, a ratchet tooth 803 is rotatably connected between the two connecting side plates 801 through a pin shaft 802. A first torsion spring 804 is arranged between one end of the pin shaft 802 and the connecting side plate 801, and a trigger bar 805 is further connected to the other end of the pin shaft 802.

[0035] At the same time, a limiting opening 806 through which the ratchet tooth 803 can pass is opened on the inner side surface of the sliding seat 8. When the ratchet tooth 803 passes through the limiting opening 806 and is engaged with the clamping groove 701 on the slide rail 7, the fixation of the sliding seat 8 can be realized. Moreover, due to the design of the limiting notch 806, the ratchet tooth 803 cannot rotate upwards after passing through the limiting opening 806 and can only rotate downwards. Therefore, when the sliding seat 8 is pushed upwards along the slide rail 7, its ratchet tooth 803 can smoothly slip out of the clamping groove 701, and when the sliding seat 8 moves downwards, the ratchet tooth 803 cannot slip out of the clamping groove 701, thereby realizing the fixation of the sliding seat 8.

[0036] Refer to Appendix Figure 3 , Appendix Figure 4 and Appendix Figure 6, a bent link assembly 9 is further provided between the sliding seat 8 and the window sash 2. The bent link assembly 9 includes a first link 901 rotatably connected to the window sash 2. A U-shaped connector 902 is provided at the movable end of the first link 901. Then, a second link 903 is rotatably connected in the U-shaped connector 902. And a second torsion spring 904 is provided between the second link 903 and the U-shaped connector 902. By the action of the second torsion spring 904, the first link 901 and the second link 903 are arranged in a straight line without external force. A rotating pin 905 is provided on the second link 903 and is rotatably connected to the outer surface of the sliding seat 8. Then, a lever 906 is connected to the movable end of the second link 903. When the movable end of the second link 903 rotates upward, its lever 906 can act on the trigger bar 805, causing the trigger bar 805 to rotate accordingly, and further causing the pawl teeth 803 to rotate downward. Finally, in order to ensure that the lever 906 has sufficient force, according to the lever principle in the specific design, the rotating pin 905 is arranged at a position close to the movable end of the second link 903.

[0037] When the intelligent window disclosed in Embodiment 1 encounters rainy weather after being opened, its water collecting trough 6 can collect the rainwater falling on the outer surfaces of the window sash 2 and the glass 3. When the rainwater in the water collecting trough 6 is increasing, the acting force exerted by the rainwater on the window sash 2 will be greater and greater. Therefore, it will press the window sash 2 to rotate downward, and further cause the rotating connection between the first link 901 and the second link 903 to bend against the acting force of the second torsion spring 904. At this time, the first link 901 bends downward, and then drives the movable end of the second link 903 to bend upward. When the movable end of the second link 903 bends upward, its lever 906 will act on the trigger bar 805, causing the pawl teeth 803 to slip out of the card slot 701 on the slide rail 7. After slipping, the sliding seat 8 will move downward along the slide rail 7. At this time, the entire window sash 2 will close in the window frame 1 under its own and the gravity of the rainwater due to the lack of supporting force, preventing the rainwater from entering the house and achieving a good rain prevention effect. Embodiment

[0038] Embodiment 2 discloses an intelligent window with rain gravity induction automatic window closing improved based on the technical solution in 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 , attached Figure 8 and attached Figure 9 .

[0039] In Embodiment 2, the water collecting trough 6 is provided with a flat bottom, and a plurality of drain holes 601 are formed in the bottom wall of the water collecting trough 6. At the same time, a drawing groove 602 for arranging a partition board is also formed inside the bottom wall of the water collecting trough 6. A partition board 10 for blocking and separating the drain holes 601 is arranged in the drawing groove 602, and through holes 101 corresponding to each drain hole 601 are formed in the partition board 10.

[0040] A connecting strip 11 is connected to the partition board 10 and passes through the lower end of the window sash 2. A buffer anti-collision block 12 is arranged at the outer end of the connecting strip 11 extending out of the window sash 2. A receiving groove 201 adapted to the buffer anti-collision block 12 is formed on the inner side surface of the lower end of the window sash 2. Then, a spring 13 is arranged between the buffer anti-collision block 12 and the receiving groove 201. Due to the supporting effect of the spring 13, the through hole 101 on the partition board 10 is misaligned with the drain hole 601 on the water collecting trough 6.

[0041] In addition, a convex plate 14 aligned with the buffer anti-collision block 12 is arranged on the bottom wall of the lower end of the window frame 1. When the ratchet tooth 803 slips out of the card slot 701 on the slide rail 7, the window sash 2 can quickly close in the window frame 1 under the action of gravity. At this time, the buffer anti-collision block 12 will first act on the convex plate 14, thereby reducing the impact force during closing. At the same time, when the window sash 2 is completely closed on the window frame 1, it will push the buffer anti-collision block 12 into the receiving groove 201. At this time, the through hole 101 is aligned with the drain hole 601, thereby realizing the drainage function.

[0042] Finally, in Embodiment 2, a magnetic adsorption strip 15 is arranged on the outer side surface of the convex plate 14 facing the outdoor. Then, a metal adsorption sheet 16 corresponding to the magnetic adsorption strip 15 is arranged on the inner side surface of the lower end of the window sash 2. When the window sash 2 is completely closed on the window frame 1, the magnetic adsorption force between the magnetic adsorption strip 15 and the metal adsorption sheet 16 can make the window sash 2 tightly closed in the window frame 1, preventing rainwater from entering the room through the gap.

[0043] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
