Technical Field

[0001] The present invention relates to the technical field of doors and windows, in particular to energy-saving building doors and windows with adjustable heat insulation strength and a use method thereof. Background Art

[0002] Building doors and windows are an important part of the building envelope. Whether they reduce indoor heat loss in cold areas or block outdoor high temperatures during hot summers, their performance directly affects building energy consumption and living comfort. Existing building door and window technologies have obvious limitations. For example, traditional technologies such as thermally-insulated aluminum and insulating glass have fixed insulation performance and cannot adapt to seasonal or weather changes. Although electrochromic glass can be dynamically adjusted, it is expensive and has limited control capabilities. Mechanical blinds are cumbersome to operate, lack automation, and have poor light transmittance.

[0003] A Chinese patent with publication number CN116065922B discloses a heat-insulating door and window, comprising a window frame and glass mounted on the window frame, wherein a first air vent is provided on the window frame on one side of the glass, and a second air vent is provided on the window frame on the other side of the glass, and the first air vent is connected to the second air vent; a first sealing column for sealing the first air vent is slidably installed in the window frame, and a second sealing column for sealing the second air vent is also slidably installed in the window frame, and a driving mechanism for driving the first sealing column and the second sealing column is installed in the window frame. However, in actual use, the heat-insulating capacity of the door and window cannot be adjusted according to changes in indoor and outdoor temperatures.

[0004] In addition, existing doors and windows with heat insulation functions have poor adaptability to changes in outdoor weather, and the adjustment method is relatively fixed, making it impossible to accurately adjust the heat insulation area of ​​the doors and windows according to the outdoor light angle.

[0010] Preferably, the traction rods on both sides are connected to the bottom ends of the traction ropes on both sides respectively, and the traction rods on both sides are connected by a connecting rod; The end of the traction rod on one side is fixedly connected to the rotating shaft of the motor arranged on the side of the movable frame.

[0011] Preferably, the liquid storage tank is arranged on the upper wall of the bottom chamber of the hollow cavity, and the top of the liquid storage tank is provided with a docking joint that penetrates the bottom surface of the air cavity wall, and the docking joint is provided with a liquid supply valve.

[0012] Preferably, the liquid supply assembly further comprises an air pump and a telescopic bag, wherein the air pump is arranged on the bottom surface of the movable frame, and the telescopic bag is arranged on the inner bottom surface of the liquid storage tank, and the telescopic bag is connected to the air supply end of the air pump through a hose.

[0013] Preferably, an insulation cavity is opened in the base, a hollow layer is opened in the middle of the insulation board, a liquid inlet head is provided at the bottom of the insulation cavity, and filling heads connected to the hollow layer are provided on both sides of the top of the insulation cavity, and a control valve is provided on the filling head.

The telescopic ends of the electric telescopic parts on both sides are respectively fixedly connected to the top positioning plates on both sides.

[0015] The present invention also provides a method for using energy-saving building doors and windows with adjustable thermal insulation strength, comprising the following steps: S1. The temperature sensor detects the outdoor temperature in real time. When the detected value is greater than a first temperature threshold, the motor drives the traction rod to rotate, and the traction rope is wound to drive the base and the insulation board downward; S2. After the joint is completely connected to the liquid inlet head, the electric telescopic part is started to drive the top positioning plates and side positioning plates on both sides to close to the insulation board, positioning and fixing the top and both sides of the insulation board; S3.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention achieves a step-by-step adjustment of thermal insulation capacity through the cooperation of a thermal insulation component and a liquid supply component. When the outdoor temperature exceeds a first threshold, the thermal insulation board automatically lowers to form a basic insulation layer. When the temperature exceeds a higher second threshold, the liquid supply component injects thermal insulation liquid into the hollow layer of the thermal insulation board, utilizing the dual thermal insulation properties of the liquid and the board to enhance the effect. At the same time, the thermal insulation strength can be fine-tuned in real time with temperature fluctuations by increasing or decreasing the injection amount of thermal insulation liquid.

[0017] 2. The present invention uses light sensors on both sides to monitor the difference in light intensity, and combines it with electromagnetic slide rails to control the position of the side positioning plates, so as to divide the hollow layer of the insulation board into multiple chambers. By injecting more insulation liquid into the chambers in the high-light area, the local insulation effect is enhanced, and the injection amount is reduced in the low-light area, thereby achieving precise insulation.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 1-10 This embodiment discloses an energy-saving building door and window with adjustable thermal insulation strength, including a movable frame 1, which is rotatably connected to a fixed frame 105 and a temperature sensor is provided on the outside of the fixed frame 105.

[0022] Specifically, the fixing frame 105 is used to be fixedly arranged in the door and window grooves, and the temperature sensor is used to monitor the outdoor temperature.

[0023] An inner embedding groove 101 and an outer embedding groove 102 for embedding glass are respectively provided on the inner and outer sides of the movable frame 1 . An air cavity wall 103 is provided around the inner middle of the movable frame 1 . The air cavity wall 103 is located between the inner embedding groove 101 and the outer embedding groove 102 .

[0024] Specifically, after the inner embedding groove 101 and the outer embedding groove 102 are respectively embedded in the glass layer, an air cavity and an air cavity wall 103 can be formed between the inner and outer glasses.

[0025] A hollow cavity 104 is formed around the interior of the movable frame 1 , and the position of the hollow cavity 104 corresponds to the position of the air cavity wall 103 .

[0026] Specifically, the hollow cavity 104 is used to improve the heat insulation and sound insulation effects of the movable frame 1 .

[0027] The top chamber of the hollow cavity 104 is provided with an insulation component 2, which includes a reel 201. The reel 201 is rotatably connected in the top chamber of the hollow cavity 104. A spiral spring 202 is sleeved on the end of the reel 201. The inner and outer ends of the spiral spring 202 are respectively fixedly connected to the reel 201 and the inner wall of the hollow cavity 104. An insulation board 203 is wound on the reel 201. The bottom end of the insulation board 203 passes through the top wall of the hollow cavity 104 and the air cavity wall 103. The insulation board 203 is made of a flexible and transparent insulation material.

[0028] A base 204 is provided at the bottom end of the heat insulation board 203, and sliders 205 are provided at both ends of the base 204 for slidingly cooperating with the side walls of the air cavity wall 103. A traction rope 206 is provided at the bottom of the slider 205, and the bottom end of the traction rope 206 passes through the bottom surface of the air cavity wall 103 and extends into the bottom chamber of the hollow cavity 104.

[0029] The thermal insulation assembly 2 also includes two symmetrically arranged traction rods 207, which are rotatably connected to both sides of the bottom chamber of the hollow cavity 104. The traction rods 207 on both sides are respectively connected to the bottom ends of the traction ropes 206 on both sides. The traction rods 207 on both sides are connected by a connecting rod 208, and the end of the traction rod 207 on one side is fixedly connected to the rotating shaft of the motor 209 provided on the side of the movable frame 1.

[0030] Specifically, the insulation board 203 is preferably made of aerogel composite material. The motor 209 is used to drive the traction rod 207 on one side to rotate, and the connecting rod 208 is used to realize the synchronous rotation of the traction rods 207 on both sides. The traction rope 206 is wound while the traction rod 207 rotates, and the winding of the traction rope 206 is used to drive the base 204 to move downward through the slider 205 to realize the unwinding of the insulation board 203. At the same time, the spiral spring 202 is elastically wound until the insulation board 203 completely covers the glass layers on the front and rear sides, and the insulation effect of the insulation board 203 itself is used to improve the insulation capacity of the doors and windows.

[0031] The top wall of the air cavity wall 103 is provided with a positioning assembly 4, which includes two corresponding top positioning plates 401, two groups of corresponding side positioning plates 402 and an electric telescopic part 403. The two top positioning plates 401 are symmetrically slidably connected to the top surface of the air cavity wall 103, and the two top positioning plates 401 are respectively attached to the two sides of the heat insulation plate 203. The two groups of side positioning plates 402 are respectively arranged at the two ends of the top positioning plate 401, and each group includes two symmetrically arranged side positioning plates 402. The two side positioning plates 402 in each group are respectively attached to the two sides of the heat insulation plate 203. The electric telescopic part 403 is provided with two groups and is respectively arranged on both sides of the top surface of the air cavity wall 103. The telescopic ends of the electric telescopic parts 403 on both sides are respectively fixedly connected to the top positioning plates 401 on both sides.

[0032] Specifically, after the insulation board 203 has completely fallen, the electric telescopic parts 403 on both sides are started to drive the top positioning plates 401 on both sides to close toward the insulation board 203, so that the top positioning plates 401 on both sides are tightly in contact with the two sides of the insulation board 203, so that the top of the stretched insulation board 203 is closed, and the insulation cavity 305 forms a closed chamber. At the same time, the movement of the top positioning plate 401 drives the two side positioning plates 402 in each group at the bottom to close toward the insulation board 203, thereby positioning the two sides of the stretched insulation board 203.

[0033] During use, the temperature sensor is used to detect the outdoor temperature value in real time. When the detected temperature value is greater than the set first temperature threshold, the motor 209 is started, and the motor 209 is used to drive the traction rod 207 to rotate, and the base 204 is driven to move downward by winding the traction rope 206. At the same time, the reel 201 rotates to cause the insulation board 203 to move downward and unwind. After the base 204 moves to the bottom of the air cavity wall 103, the docking head 302 is completely docked with the liquid inlet head 306, and the motor 209 stops rotating. Then, the electric telescopic part 403 is started to drive the top positioning plates 401 on both sides to merge toward the insulation board 203, and the top of the stretched insulation board 203 is squeezed and resisted to achieve positioning of the top of the insulation board 203. At the same time, the side positioning plates 402 on both sides of the insulation board 203 squeeze and resist the two sides of the stretched insulation board 203 as the top positioning plate 401 moves, and the two sides of the insulation board 203 are positioned, thereby achieving overall fixation of the insulation board 203 and preventing the insulation board 203 from resetting.

[0034] Furthermore, a liquid supply component 3 is provided between the bottom of the hollow cavity 104 and the insulation component 2. The liquid supply component 3 includes a liquid storage tank 301. The liquid storage tank 301 is provided on the upper wall of the bottom chamber of the hollow cavity 104. The liquid storage tank 301 stores insulation liquid. The top of the liquid storage tank 301 is provided with a docking joint 302 that passes through the bottom surface of the air cavity wall 103. The docking joint 302 is provided with a liquid supply valve 303. The insulation liquid is preferably a transparent ATO solution.

[0035] The liquid supply assembly 3 also includes an air pump 304 and a telescopic bag 3041. The air pump 304 is arranged on the bottom surface of the movable frame 1, and the telescopic bag 3041 is arranged on the inner bottom surface of the liquid storage tank 301. The telescopic bag 3041 is connected to the air delivery end of the air pump 304 through a hose. An insulating cavity 305 is provided in the base 204. The insulating cavity 305 is used for the entry and diversion of insulating liquid. A hollow layer 307 is provided in the middle of the insulating plate 203. The hollow layer 307 is used to be filled with insulating liquid. A liquid inlet head 306 is provided at the bottom of the insulating cavity 305, and filling heads 308 connected to the hollow layer 307 are provided on both sides of the top of the insulating cavity 305. A control valve is provided on the filling head 308.

[0036] Specifically, after the base 204 is completely dropped, the bottom surface contacts the bottom surface of the air cavity wall 103, and at the same time, the liquid inlet head 306 is inserted into the docking joint 302 to complete the docking, and then the liquid supply valve 303 and the control valve are opened, and the air pump 304 is started to supply air to the telescopic bag 3041, so that the telescopic bag 3041 extends upward, and at the same time pushes the insulation liquid upward, so that the insulation liquid enters the insulation cavity 305 through the docking joint 302 and the liquid inlet head 306, and the continuous pressurization of the telescopic bag 3041 allows the insulation liquid to continue to enter the hollow layer 307 through the filling head 308. After the hollow layer 307 is filled with the insulation liquid, a layer of insulation liquid interlayer can be formed inside the insulation board 203, and the insulation effect of the insulation board 203 and the insulation liquid can be used to further improve the insulation capacity.

[0037] During use, by setting a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold, when the temperature sensor detects that the outdoor temperature is greater than the set second temperature threshold, it is actively judged that the outdoor temperature is in high heat weather. At this time, the liquid supply valve 303 and the control valve are opened, and the air pump 304 is started to inflate the bellows 3041, so that the thermal insulation liquid in the liquid storage tank 301 is pressed into the thermal insulation cavity 305 by the bellows 3041, and enters the hollow layer 307 through the filling head 308, so that the thermal insulation liquid fills the hollow layer 307, further enhancing the thermal insulation effect of the thermal insulation board 203 In addition, a temperature sensor is used to detect the outdoor temperature value in real time. As the temperature value increases, insulating liquid can be continuously injected into the hollow layer 307, so that the insulation board 203 expands slightly and the thickness increases, thereby further enhancing the insulation effect. On the basis that the outdoor temperature is greater than the set second temperature threshold, when the outdoor temperature drops, air is pumped out through the air pump 304 to shrink the telescopic bag 3041, so that the insulating liquid is returned to the liquid storage tank 301, and the insulation strength of the insulation board 203 can be appropriately reduced, thereby achieving the purpose of adjusting the insulation strength of the insulation board 203 according to the outdoor temperature.

[0038] Example 2 In actual use, especially when the outdoor light intensity is high, the sunlight shining on the doors and windows superimposed on the ambient temperature will make the door and window temperature much higher than the ambient temperature, and more heat will be transferred into the room. Therefore, the following improvements are made: Light sensors 106 are respectively provided on both sides of the exterior of the movable frame 1 . The light sensors 106 provided on both sides are used to monitor the light intensity on both sides of the movable frame 1 respectively.

[0039] Electromagnetic slide rails 404 are provided on both sides of the bottom of the top positioning plate 401 on each side, and the top end of the side positioning plate 402 is fixedly connected to the sliding part on the corresponding electromagnetic slide rail 404. The setting of the electromagnetic slide rail 404 enables the side positioning plate 402 to slide horizontally along the bottom surface of the top positioning plate 401 to adjust the position of the side positioning plate 402.

[0040] During use, when the light sensor 106 on one side detects that the light intensity on that side is higher, before injecting the insulation liquid into the hollow layer 307, the electric telescopic part 403 is first used to drive the top positioning plates 401 on both sides of the insulation board 203 away to release the squeezing and resistance to the insulation board 203, and at the same time, the motor 209 provides a downward traction force on the insulation board 203 to prevent the insulation board 203 from rolling up and resetting, and then the electromagnetic slide rails 404 on both sides of the insulation board 203 on one side are synchronously started to synchronously drive the two side positioning plates 402 on that side to move along the width direction of the insulation board 203, and the side positioning plates 402 move to the middle of the insulation board 203 and stop, and the electric telescopic part 403 is used again to drive the top positioning plates 401 on both sides to squeeze and resist the top two sides of the insulation board 203, and at the same time, the side positioning plates 402 squeeze and resist the middle of the insulation board 203. By utilizing the corresponding squeezing and resisting of the side positioning plates 402 on both sides on the two sides of the insulation board 203, the hollow layer 307 in the insulation board 203 is divided into multiple chambers, and each chamber has a corresponding filling head 308. Then, the liquid supply valve 303 and the control valve are opened, and the flux of the control valve on the side with high light intensity is made greater than the flux of the control valve on the side with low light intensity. Thus, while injecting insulation liquid into the hollow layer 307, more insulation liquid enters the chamber on the side with high light intensity, thereby increasing the insulation effect of the insulation board 203 while further increasing the insulation effect on the side of the insulation board 203 close to the high light intensity, thereby improving the insulation efficiency, achieving precise insulation, and avoiding the phenomenon of uneven insulation. Moreover, as the light intensity and angle change, the position of the side positioning plate 402 can be adjusted in real time to accurately adjust the insulation intensity of the insulation area to the greatest extent.

[0041] Example 3 This embodiment provides a method for using energy-saving building doors and windows with adjustable thermal insulation strength, comprising the following steps: S1. The temperature sensor detects the outdoor temperature in real time. When the detected value is greater than a first temperature threshold, the motor 209 drives the traction rod 207 to rotate, and the traction rope 206 is wound to drive the base 204 and the heat insulation board 203 to move downward; Specifically, when the motor 209 drives the traction rod 207 on one side to rotate, the traction rod 207 on the other side is synchronously driven to rotate through the connecting rod 208, so that the traction ropes 206 on both sides are synchronously wound; the sliders 205 at both ends of the base 204 slide along the side walls of the air cavity wall 103 to ensure that the insulation board 203 is vertically lowered; the reel 201 rotates synchronously with the unwinding of the insulation board 203, and the spiral spring 202 elastically contracts to store potential energy until the bottom surface of the base 204 contacts the bottom of the air cavity wall 103, at which time the insulation board 203 is fully unfolded to cover the glass area.

[0042] S2. After the docking joint 302 is completely docked with the liquid inlet head 306, the electric telescopic part 403 is started to drive the top positioning plate 401 and the side positioning plates 402 on both sides to close toward the heat insulation board 203, thereby positioning and fixing the top and both sides of the heat insulation board 203; Specifically, the electric telescopic part 403 extends and pushes the top positioning plates 401 on both sides to slide along the top surface of the air cavity wall 103 until they are tightly fitted to the two sides of the top of the heat insulation board 203, closing the gap between the heat insulation board 203 and the air cavity wall 103; at the same time, the electromagnetic slide rail 404 at the bottom of the top positioning plate 401 drives the side positioning plates 402 to move closer to the two sides of the heat insulation board 203, and each group of two side positioning plates 402 respectively fits the two side surfaces of the heat insulation board 203, forming an all-round fixation of the top and sides of the heat insulation board 203, preventing it from resetting under the action of the spiral spring 202.

[0043] S3. When the temperature sensor detects that the outdoor temperature is greater than the second temperature threshold, the liquid supply valve 303 and the control valve are opened, and the air pump 304 is started to inflate the bellows 3041, allowing the insulation liquid to enter the hollow layer 307 to enhance the insulation effect. The insulation strength is adjusted by controlling the amount of insulation liquid injected. Specifically, the insulating liquid stored in the liquid storage tank 301 is a transparent ATO solution. The air pump 304 inflates the telescopic bag 3041, squeezing the insulating liquid in the liquid storage tank 301 and entering the insulating cavity 305 of the base 204 through the docking joint 302 and the liquid inlet head 306; the insulating liquid flows into the hollow layer 307 of the insulation board 203 through the filling head 308 at the top of the insulation cavity 305. As the injection amount increases, the thickness of the insulating liquid in the hollow layer 307 increases, and combined with the material of the insulation board 203 itself, double insulation is formed; when the outdoor temperature drops, the air pump 304 draws air to cause the telescopic bag 3041 to shrink, and the insulating liquid flows back to the liquid storage tank 301, reducing the amount of liquid in the hollow layer 307 and reducing the insulation strength.

[0044] S4. When the light intensity on one side of the fixed frame 105 is high, the electric telescopic unit 403 is first used to move the top positioning plate 401 away from the heat insulation board 203, and the traction force of the motor 209 is used to temporarily position the heat insulation board 203. Then, the electromagnetic slide rail 404 on one side is activated to drive the side positioning plates 402 on both sides to move to the middle of the heat insulation board 203. Then, the electric telescopic unit 403 drives the top positioning plate 401 and the side positioning plates 402 to restore the heat insulation board 203 to its original position. At this time, the hollow layer 307 is divided into multiple chambers. Specifically, the light sensors 106 on both sides of the movable frame 1 respectively detect the light intensity on both sides. When the light value on one side is significantly higher than that on the other side, the electric telescopic part 403 contracts to make the top positioning plate 401 separate from the insulation board 203, and the motor 209 maintains the traction force on the traction rope 206 to prevent the insulation board 203 from moving up; the electromagnetic slide rail 404 on the side with lower light intensity is started, and its sliding part drives the side positioning plate 402 to slide along the bottom surface of the top positioning plate 401 to the middle of the insulation board 203, and the side positioning plates 402 on both sides are symmetrically distributed; the electric telescopic part 403 is started again to make the top positioning plate 401 and the side positioning plate 402 re-clamp the insulation board 203. At this time, the side positioning plate 402 divides the hollow layer 307 into multiple independent chambers, corresponding to the high light area and the low light area respectively.

[0045] S5. Finally, the liquid supply valve 303 and the control valve are opened to make the flux of the control valve on the high light intensity side greater than that on the low light intensity side, and to inject insulation liquid into the corresponding chamber to achieve differentiated and precise insulation.

[0046] Specifically, when supplying liquid, the filling head 308 on the side with high light intensity controls the valve opening to a wider degree, allowing more insulation liquid to flow into the hollow layer 307 of the corresponding chamber, thereby increasing the thickness of the insulation liquid in this area; the control valve opening on the side with low light intensity is smaller, reducing the amount of liquid injected; since both the insulation board 203 and the insulation liquid are made of transparent materials, they will not affect the light transmittance of doors and windows; through this local enhancement method, the insulation effect of the high light area is more significant.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
