Description

Technical Field

[0001] This invention belongs to the field of building technology science and technology, and relates to the control of shading and heat preservation of exterior windows, specifically to an exterior window shading and heat preservation control device adapted to indoor needs. Background Technology

[0002] Existing building window and door shading components are mainly divided into fixed, casement, sliding, and adjustable-angle blade types. Their blades generally lack vertical displacement adjustment capabilities. This limitation affects the visual transparency and openness of the window, and may also restrict natural lighting and ventilation. Compared to indoor shading curtains, external shading systems, which place shading devices on the outside of building windows, can effectively block solar radiation before it reaches the window surface, significantly reducing solar heat, ultraviolet rays, and glare entering the room. This has a positive effect on reducing indoor heat load and improving the energy efficiency of air conditioning systems.

[0003] However, current common building exterior louver systems typically have fixed slat spacing, making it difficult to flexibly adjust according to different seasons, times of day, and varying weather conditions, thus lacking adaptability to complex climate situations. Louvers or sunshades installed inside windows, on the other hand, often only become effective after heat has already entered the window or interior space, resulting in relatively limited blocking of solar radiation. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an exterior window shading and heat preservation control device that adapts to indoor needs, and to solve the technical problem that the flexibility of the blades of the building door and window shading components in the existing technology needs to be further improved.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0006] A window shading and heat insulation control device adapted to indoor needs includes a left frame and a right frame with the same structure and size. The left frame and the right frame are arranged on the outside of the wall with the window and perpendicular to the wall. The left frame and the right frame are symmetrically installed on the left and right sides of the window on the wall.

[0007] The inner sides of the left and right frames are provided with multiple independent blades arranged horizontally, and the blades are evenly arranged vertically. The right side wall of the left frame is also equipped with multiple left-side rotary motors that can slide vertically, and the output shafts of the left-side rotary motors are connected to the left side wall of the blades and correspond one-to-one. The left side wall of the right frame is also equipped with multiple right-side rotary motors that can slide vertically, and the output shafts of the right-side rotary motors are connected to the right side wall of the blades and correspond one-to-one. By synchronously driving the left-side and right-side rotary motors connected to each blade, the guidance and flipping of each blade can be achieved.

[0008] The vertical sliding mounting points of two adjacent left-side rotary motors are flexibly connected, and a left-side lifting rope is also included. The left-side lifting rope passes through all the vertical sliding mounting points of the left-side rotary motors in sequence along the vertical direction. The vertical sliding mounting points of two adjacent right-side rotary motors are flexibly connected, and a right-side lifting rope is also included. The right-side lifting rope passes through all the vertical sliding mounting points of the right-side rotary motors in sequence along the vertical direction. The lifting and lowering of all blades is achieved by simultaneously raising and lowering the left-side and right-side lifting ropes from the top vertically.

[0009] The present invention also has the following technical features.

[0010] Specifically, the left frame includes a left frame body, and a left sliding groove is arranged vertically on the right side wall of the left frame body. Multiple left sliders are embedded in the left sliding groove, and each left slider corresponds to a blade. The right side of the left slider is also connected to a left rotary motor, and each left slider corresponds to a left rotary motor. The right output shaft of the left rotary motor is also connected to the middle of the left side wall of the blade.

[0011] The structure and size of the right-side rotary motor are the same as those of the left-side rotary motor. The multiple right-side rotary motors and the multiple left-side rotary motors are arranged symmetrically in a plane perpendicular to the horizontal direction. The sliding installation method of the multiple right-side rotary motors on the right-side frame is the same as that of the multiple left-side rotary motors on the left-side frame.

[0012] Specifically, the left slider includes a left slider body, and a vertically penetrating left slider through hole is coaxially opened on the left slider body. The inner diameter of the left slider through hole is greater than or equal to the outer diameter of the left lifting rope. The left lifting rope passes through all the left slider through holes in sequence along the vertical direction, and one end of the left lifting rope is clamped outside the vertical bottom of the left slider through hole located at the bottom vertically.

[0013] The vertical bottom end face of the left slider is connected to the vertical top end face of another left slider adjacent to the vertical bottom by multiple left connecting ropes. The multiple left connecting ropes are symmetrically installed on the left and right sides of the horizontal through hole of the left slider.

[0014] Specifically, all blades are in a fully open horizontal state before lifting or lowering.

[0015] The length of the left connecting rope in its fully extended vertical state is sufficient to allow two adjacent vertical blades to achieve a fully closed vertical state.

[0016] Specifically, the top of the left frame and the top of the right frame are also equipped with the same top mounting plate, and the multiple blades are arranged at the vertical bottom of the top mounting plate.

[0017] The aforementioned top mounting plate is installed on the top of the window on the wall.

[0018] A left linear lifting motor is also installed on the top surface of the top mounting plate. A vertical through hole for the left lifting rope is also provided on the top mounting plate near the horizontal left side wall. The other end of the left lifting rope passes through the left lifting rope through hole and is installed on the left linear lifting motor.

[0019] Specifically, the flexible connection method of the vertical sliding mounting of the right rotary motor is the same as that of the vertical sliding mounting of the left rotary motor.

[0020] The vertical sliding drive method of the vertical sliding mounting point of the right rotary motor is the same as that of the vertical sliding drive method of the left rotary motor.

[0021] Specifically, the blades are filled with insulating material.

[0022] Specifically, the insulation material includes polyurethane foam.

[0023] Compared with the prior art, the present invention has the following technical effects.

[0024] (I) The rotation angle of each blade in the device of the present invention can be adjusted independently, and all blades can be raised and lowered, which effectively improves the flexibility of adjustment compared with the fixed spacing of blades in the prior art.

[0025] (II) All the left-side rotary motors and all the right-side rotary motors in the device of the present invention are arranged in the middle of the inner side of the left-side frame and the right-side frame, and are fully protected by the left-side frame and the right-side frame, and have good windproof, rainproof, dustproof and weather-resistant performance.

[0026] (III) The rotation angle of each blade in the device of the present invention can be adjusted independently, supporting the formation of a dynamic shading array with variable angle on the building facade. It can be finely adjusted according to the solar azimuth angle and radiation intensity, significantly improving the energy-saving effect and thermal comfort of the building's exterior windows.

[0027] (IV) The device in this invention has a high degree of modularity, which makes it easy to install, maintain and replace parts, and has wide applicability. Attached Figure Description

[0038] Example:

[0039] This embodiment provides an exterior window shading and heat preservation control device adapted to indoor needs, such as... Figure 1 As shown, it includes a left frame 1 and a right frame 2 with the same structure and size. The left frame 1 and the right frame 2 are arranged outside the wall 3 with windows and perpendicular to the wall 3. The left frame 1 and the right frame 2 are symmetrically installed on the left and right sides of the windows on the wall 3.

[0040] like Figure 2 and Figure 3 As shown, multiple independent blades 4 are arranged horizontally on the inner sides of the left frame 1 and the right frame 2, and the multiple blades 4 are evenly arranged vertically. Multiple left-side rotary motors 5 that can slide vertically are also installed on the right side wall of the left frame 1. The output shafts of the left-side rotary motors 5 are connected to the left side wall of the blades 4 and correspond one-to-one. Multiple right-side rotary motors 6 that can slide vertically are also installed on the left side wall of the right frame 2. The output shafts of the right-side rotary motors 6 are connected to the right side wall of the blades 4 and correspond one-to-one. By synchronously driving the left-side rotary motors 5 and right-side rotary motors 6 connected to each blade 4, the guidance and flipping of each blade 4 are realized.

[0041] The vertical sliding mounting points of two adjacent left-side rotary motors 5 are flexibly connected, and a left-side lifting rope 7 is also included. The left-side lifting rope 7 passes through all the vertical sliding mounting points of the left-side rotary motors 5 in sequence along the vertical direction. The vertical sliding mounting points of two adjacent right-side rotary motors 6 are flexibly connected, and a right-side lifting rope is also included. The right-side lifting rope passes through all the vertical sliding mounting points of the right-side rotary motors 6 in sequence along the vertical direction. The lifting and lowering of all blades 4 is achieved by simultaneously raising and lowering the left-side lifting rope 7 and the right-side lifting rope from the top vertical direction.

[0042] In this embodiment, all blades 4 have the same structure, size and material, and the lateral length of blade 4 is greater than the lateral length of the window on the wall 3; the shape of blade 4 is preferably rectangular in cross-section, such as the blade of a venetian blind commonly known in the art.

[0043] In this embodiment, the left frame 1 and the right frame 2 are fixedly installed on the outer walls of the windows on the left and right sides of the wall 3.

[0044] In this embodiment, when all blades 4 are in a fully closed vertical state, the vertical height of all blades 4 is greater than the vertical height of the window on the wall 3.

[0045] In this embodiment, the left output shaft of the right rotary motor 6 is also connected to the middle of the transverse right side wall of the blade 4.

[0046] In this embodiment, during the process of adjusting all blades 4 to move vertically up and down, all blades 4 are in a fully open horizontal state.

[0047] As a preferred embodiment of this invention, such as Figure 2 As shown, the left frame 1 includes a left frame body 101. A left slide groove 102 is also arranged vertically on the right side wall of the left frame body 101. Multiple left sliders 103 are also embedded in the left slide groove 102. The left sliders 103 correspond one-to-one with the blades 4. The right side of the left sliders 103 is also connected to the left rotary motor 5. The right output shaft of the left rotary motor 5 is also connected to the middle of the left side wall of the blade 4.

[0048] The structure and size of the right-side rotary motor 6 are the same as those of the left-side rotary motor 5. Multiple right-side rotary motors 6 and multiple left-side rotary motors 5 are arranged symmetrically in a plane perpendicular to the horizontal plane. The sliding installation method of multiple right-side rotary motors 6 on the right-side frame 2 is the same as that of multiple left-side rotary motors 5 on the left-side frame 1.

[0049] As a preferred embodiment of this invention, such as Figure 3 As shown, the left slider 103 includes a left slider body 10301. The left slider body 10301 is also coaxially provided with a vertically penetrating left slider through hole 10302. The inner diameter of the left slider through hole 10302 is greater than or equal to the outer diameter of the left lifting rope 7. The left lifting rope 7 passes through all the left slider through holes 10302 in sequence along the vertical direction. One end of the left lifting rope 7 is clamped outside the vertical bottom of the left slider through hole 10302 located at the bottom vertically.

[0050] The vertical bottom end face of the left slider 103 is connected to the vertical top end face of another left slider 103 adjacent to the vertical bottom by multiple left connecting ropes 8. The multiple left connecting ropes 8 are symmetrically installed on the left and right sides of the horizontal through hole 10302 of the left slider.

[0051] In this embodiment, one end of the left lifting rope 7 is secured to the bottom of the left slider through hole 10302 located at the bottom vertically by a knot; one end of the right lifting rope is also secured to the bottom of the right rotary motor 6 located at the bottom vertically by a knot.

[0052] As a preferred embodiment, all blades 4 are in a fully open horizontal state before lifting.

[0053] The length of the left connecting rope 8 in its fully extended vertical state is sufficient to allow two adjacent vertical blades 4 to achieve a fully closed vertical state.

[0054] As a preferred embodiment of this invention, such as Figure 1As shown, the top of the left frame 1 and the top of the right frame 2 are also equipped with the same top mounting plate 9, and multiple blades 4 are arranged at the vertical bottom of the top mounting plate 9.

[0055] The top mounting plate 9 is installed on the top of the window on the wall 3.

[0056] A left linear lifting motor 10 is also installed on the top surface of the top mounting plate 9. A vertical through hole for the left lifting rope is also provided on the top mounting plate 9 near the horizontal left side wall. The other end of the left lifting rope 7 passes through the left lifting rope through hole and is installed on the left linear lifting motor 10.

[0057] In this embodiment, the left linear lifting motor 10 is a winch, and the winch adopts a commonly used winch known in the art.

[0058] In this embodiment, a right linear lifting motor 11 is also installed on the top surface of the top mounting plate 9. A vertical through hole for the right lifting rope is also provided on the top mounting plate 9 near the horizontal right side wall. The other end of the right lifting rope passes through the right lifting rope through hole and is installed on the right linear lifting motor 11.

[0059] As a preferred embodiment, the soft connection method of the vertical sliding mounting of the right rotary motor 6 is the same as that of the soft connection method of the vertical sliding mounting of the left rotary motor 5.

[0060] The vertical sliding drive method of the vertical sliding mounting point of the right rotary motor 6 is the same as that of the vertical sliding mounting point of the left rotary motor 5.

[0061] As a preferred embodiment, the blade 4 is filled with thermal insulation material.

[0062] As a preferred embodiment, the insulation material includes polyurethane foam.

[0063] In this embodiment, the thermal insulation material is a commonly known thermal insulation material in the art; the polyurethane foam is a commonly known polyurethane foam in the art.

[0064] In this embodiment, when adjusting the rotation angle (i.e., flip angle) of the blade 4, the device synchronously drives the left rotary motor 5 and the right rotary motor 6 connected to each blade 4 to guide and flip each blade 4; in addition, the rotation angle of all blades 4 can be adjusted independently.

[0065] In this embodiment, when adjusting all blades 4 to rise and fall vertically, the device first ensures that all blades 4 are in a fully open horizontal state. By synchronously driving the left linear lifting motor 10 and the right linear lifting motor 11, the left lifting rope 7 and the right lifting rope are synchronously extended and retracted, thereby realizing the lifting and lowering of all left rotary motors 5 and all right rotary motors 6, and finally realizing the vertical lifting and lowering of all blades 4.

[0066] As a further preferred embodiment, a solar radiation sensor 12 is also installed on the vertical top surface of the top mounting plate 9 to detect the solar radiation intensity.

[0067] Mode 1, Summer Daytime Shading Strategy: When the solar radiation sensor 12 detects that the daytime solar radiation intensity exceeds the set threshold of the solar radiation sensor 12, the left linear lifting motor 10 and the right linear lifting motor 11 are driven synchronously to adjust all blades 4 to descend vertically to the front of the window on the wall 3; and as needed, the left rotary motor 5 and the right rotary motor 6 connected to each blade 4 are driven synchronously to guide and flip each blade 4, thereby forming an effective shading surface.

[0068] Mode 2, Summer Nighttime Heat Dissipation Strategy: When it is nighttime or below the set threshold of the solar radiation sensor 12, all blades 4 are adjusted to a fully open horizontal state. By synchronously driving the left linear lifting motor 10 and the right linear lifting motor 11, all blades 4 are raised vertically until all blades 4 are at the top of the window on the wall 3, so that the window on the wall 3 is fully exposed, which is conducive to the dissipation of indoor heat and natural ventilation.

[0069] Mode 3, Winter Insulation and Protection Strategy: When the outdoor temperature is below the set threshold of the solar radiation sensor 12 and the outdoor temperature is low, all blades 4 are adjusted to descend vertically to the front of the window on the wall 3 by synchronously driving the left linear lifting motor 10 and the right linear lifting motor 11. Then, by synchronously driving the left rotary motor 5 and the right rotary motor 6 connected to each blade 4, all blades 4 are adjusted to a fully closed vertical state. At this time, all blades 4 filled with insulation material, the left frame 1 and the right frame 2 together form a closed insulation and protection layer, forming a complete insulation shell covering the outside of the window on the wall 3, which significantly improves the insulation performance of the window and reduces heat loss at the window.
