Description

Technical Field

[0001] This invention belongs to the field of door and window technology, and in particular relates to a green and energy-saving door and window structure. Background Technology

[0002] Typically, doors and windows are shaded by indoor blackout curtains. However, indoor blackout curtains do not completely block light from entering the room. Especially in summer, light can penetrate the glass of doors and windows and reach the room, causing the indoor temperature to rise and putting more strain on indoor cooling equipment.

[0003] Meanwhile, doors and windows, as an important component of the building envelope, play a crucial role in energy conservation. In energy-efficient buildings, the area of ​​doors and windows accounts for approximately one-seventh of the total building area, yet their energy consumption accounts for more than half of the building's total energy consumption. The rational use of doors and windows is of paramount importance for promoting green building practices.

[0004] Therefore, how to block a large amount of light from entering the room during periods of high light intensity, while making reasonable use of the sunlight that shines on the glass of doors and windows, has become a key issue that needs to be considered in the development of green and energy-saving doors and windows.

[0005] Therefore, this invention proposes a green and energy-saving door and window structure that uses a light-blocking component to block light and generate electricity during hot seasons or periods. When indoor lighting is needed, the light-blocking component can be retracted to allow light to enter the room. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a green and energy-saving door and window structure, aiming to solve or improve at least one of the aforementioned technical problems.

[0007] To achieve the above objectives, the present invention provides a green and energy-saving door and window structure, including a window frame and a fixed window body. The fixed window body comprises double-glazed glass, and a light-shielding component storage area is provided at the top of the fixed window body between the double-glazed glass. A light-shielding component that can be rolled up and extended downwards between the double-glazed glass is located within the light-shielding component storage area. The light-shielding component is driven to unfold and rewind by a rewinding component. The light-shielding component includes multiple vertically stacked photovoltaic panels that are slidably connected in sequence.

[0008] Preferably, the winding assembly includes a plurality of winding slides connected in sequence, each of the winding slides being fixed to both sides of the photovoltaic panel and driven to slide up and down by a winding motor.

[0009] Preferably, the winding slide bar has multiple teeth distributed from top to bottom on the opposite side of the photovoltaic panel for meshing with the drive end of the winding motor.

[0010] Preferably, the drive end of the winding motor is connected to a large gear, which simultaneously meshes with each of the winding slides.

[0011] Preferably, the drive end of the winding motor is connected to a drive gear, and each winding slide is engaged with an independent driven gear, with the drive gear engaging with each driven gear in sequence.

[0012] Preferably, a permanent magnet is fixedly connected to the window frame directly above the winding slider, and each winding slider is magnetically connected to the permanent magnet.

[0013] Preferably, the winding slide is made of aluminum alloy and has a magnetic block fixed to its top, which is magnetically connected to the permanent magnet.

[0014] Preferably, a telescopic module is provided between the drive gear and the winding motor, and the telescopic module drives the drive gear to slide along the interval direction of each driven gear.

[0015] Preferably, a slide rod is provided on the side of the drive gear away from the winding motor. The slide rod is rotatably connected to the drive gear bearing and slides along the interval direction of each driven gear as the drive gear moves. Locking teeth that mesh with each driven gear are raised on the rod surface of the slide rod near each driven gear.

[0016] Preferably, the photovoltaic panel is a lightweight ultra-thin photovoltaic module, including front glass with a thickness of ≤2mm.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention relates to a green and energy-saving door and window structure that fully utilizes the gap between double-glazed windows. A light-blocking component is installed between the two panes to prevent light from entering the room. This component uses photovoltaic panels, achieving both shading and power generation through the use of sunlight. Simultaneously, a storage area for each photovoltaic panel is located at the top of the window frame, and a retractable assembly completes the retraction process. This allows for flexible switching between retraction and unfolding, adapting to different indoor lighting needs while maintaining aesthetics and energy efficiency. When the photovoltaic panels are unfolded, they are sequentially assembled to form a unified light-blocking component, blocking the light path from the fixed window frame and significantly reducing the amount of light entering the room. This alleviates the workload on indoor cooling equipment. Furthermore, each photovoltaic panel generates electricity using sunlight, providing power to indoor electrical appliances, further achieving energy savings. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] The following is combined Figures 1-4 The green and energy-saving door and window structure of Embodiment 1 of the present invention is described.

[0035] refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 A schematic diagram of a green and energy-saving door and window structure according to Embodiment 1 of the present invention is shown. Figure 1 This diagram shows the front view of the door and window structure under normal conditions. Figure 2 The front view of this door and window structure is shown in the power generation state.

[0036] like Figure 1 and Figure 2As shown, this window and door structure includes a window frame 600, a fixed window body 100 located in the middle of the window frame 600, and movable window sashes 300 connected to the window frames on both sides of the fixed window body 100. The fixed window body 100 has a shading component storage area 200 at the top, and the rest is double-layered transparent glass fixed inside the window frame. Multiple ultra-thin photovoltaic panels 400 are rolled up in the shading component storage area 200 as shading components. The photovoltaic panels 400 are stacked and stored in the shading component storage area 200 by the rolling component 500. When unfolded, they can fill the entire fixed window body 100. Multiple photovoltaic panels 400 descend sequentially from the shading component storage area 200 and are arranged from high to low between the double-layered transparent glass to absorb sunlight for power generation.

[0037] Specifically, the photovoltaic panel 400 adopts a lightweight and ultra-thin tandem photovoltaic module, including an opaque backsheet, ultra-thin glass, and multiple interconnected solar cells 401 laminated between the backsheet and the glass. The thickness of the ultra-thin glass is ≤2mm, for example, Amaton ultra-thin photovoltaic glass can be used. The length of a single photovoltaic panel 400 is slightly smaller than the width of the fixed window 100, and the height is slightly smaller than the height of the shading component storage area 200. In this embodiment, the height is preferably sufficient to accommodate two strings of solar cells 401. Each photovoltaic panel 400 has a winding slide bar fixed on both sides, and is electrically connected to the winding slide bar via solder strips / busbars. The winding slide bars of each photovoltaic panel 400 are slidably connected to each other and electrically connected, and finally connected to the junction box / connector via wires.

[0038] It should be understood that the photovoltaic panel 400 can also use double-glass modules. The advantage of using double-glass modules is that the photoelectric conversion efficiency is high and the power generation is high. The disadvantage is that the shading effect is poor and the thickness and weight of a single photovoltaic panel 400 are increased. With the same number of photovoltaic panels 400, the thickness of a single fixed window 100 is increased, and the cost is relatively high.

[0039] like Figure 3As shown, the winding assembly 500 includes a first winding slide bar 501, a second winding slide bar 502, a third winding slide bar 503, a fourth winding slide bar 504, and a fifth winding slide bar 505, which are slidably connected in sequence. The first winding slide bar 501 is located on the innermost side, and the fifth winding slide bar 505 is located on the outermost side, and the fifth winding slide bar 505 is slidably connected to the inner side of the window frame 600. To increase structural stability, each winding slide bar includes two sub-slide bars, one on the left and one on the right. The outer sides of the two sub-slide bars are slidably connected to the inner sides of the two sub-slide bars of the next winding slide bar. The back sides of the two sub-slide bars are connected to form a whole, and the back side is connected to the edge of the photovoltaic panel 400. The front sides of the two sub-slide bars have multiple teeth 5002 evenly distributed from top to bottom, which mesh with the large gear 507 that drives each winding slide bar to slide up and down. A fixing mechanism is fixed inside the window frame 600 above the winding assembly 500. The fixing mechanism is a permanent magnet 700, which is used to attract each winding slide. Correspondingly, a magnetic block or metal block that cooperates with the permanent magnet 700 is fixed to the top of each winding slide.

[0040] In some embodiments, each winding slider is configured as a conductive, lightweight metal structure, such as aluminum alloy, and a magnetic block or a magnetically conductive metal block, such as iron, is fixed to its top.

[0041] In some other embodiments, to reduce weight, the winding slider may be configured as a plastic structure with conductive wires connected inside and a magnetic block or magnetically conductive metal block fixed to its top.

[0042] like Figure 4 As shown, the large gear 507 is rotatably connected to the window frames 600 on both sides at both ends, and a winding motor 506 is connected to one end for transmission. The winding motor 506 provides rotational power to drive the large gear 507 to rotate in the forward / reverse direction. The large gear 507 sequentially drives each winding slide bar to slide down to unfold or slide up to rewind, thereby enabling the photovoltaic panels 400 fixed on the back of each winding slide bar to unfold or slide into the shading component storage area 200.

[0043] The connection relationships of each winding slider can be referenced. Figure 9 As shown, Figure 9The connection relationship of each winding slider in Embodiments 1 and 2 is shown. The figure only takes the first winding slider 501 and the second winding slider 502 as examples. The side of the two winding sliders with teeth 5002 is defined as the front. A photovoltaic panel 400 is connected to the rear side of the first winding slider 501 and the second winding slider 502. A slider 5001 and a groove 5003 are respectively provided on the two sides of the first winding slider 501 and the second winding slider 502. The slider 5001 protrudes outward and is positioned below the top of the winding slider. When the slider 5001 slides to the top of the groove 5003, it ensures that the two winding sliders are at the same height, allowing each winding slider to be fully wound. The groove 5003 is a long groove recessed inward towards the winding slider. A side slot is provided within the groove to engage the slider 5001. When the slider 5001 engages in the groove 5003, it can only reciprocate along its length. The top and bottom of the groove 5003 are respectively a certain distance from the top and bottom surfaces of the winding slider. This serves two purposes: first, to prevent the slider 5001 from dislodging, and second, to achieve linkage. When the first winding slide bar 501 slides downward under the drive of the large gear 507, the slider 5001 on the first winding slide bar 501 slides to the bottom of the groove 5003 of the second winding slide bar 502. The first winding slide bar 501 continues to move downward. At this time, the first winding slide bar 501 and the second winding slide bar 502 change from sliding to transmission connection. The second winding slide bar 502 receives a downward driving force. At this time, the second winding slide bar 502 overcomes the magnetic attraction of the top permanent magnet 700 and moves downward. Furthermore, the teeth 5002 on the front of the second winding slide bar 502 begin to mesh with the large gear 507.

[0044] like Figure 4 As shown, for the purpose of differentiation, the teeth on the first take-up slide 501 are defined as the first slide tooth 50101, and the teeth on the second take-up slide 502 are defined as the second slide tooth 50201. When the slider 5001 reaches the end of the stroke of the slide groove 5003, the first slide tooth 50101 on the first take-up slide 501 and the second slide tooth 50201 on the second take-up slide 502 are at the same horizontal height. At this time, the two can mesh into the large gear 507 at the same time, which realizes the linkage between the previous take-up slide and the next take-up slide.

[0045] The upward winding process is the opposite of the downward unfolding process. Driven by the reverse rotation of the large gear 507, each winding slider moves upward in sequence. When the last tooth 5002 disengages from the large gear 507, the winding slider enters the magnetic attraction range of the top permanent magnet 700. Under the magnetic force of the permanent magnet 700, it is attracted to the top and fixed on the top of the light-shielding component storage area 200. When all winding sliders are fixed on the top, the winding is completed.

[0046] The beneficial effects of this embodiment 1:

[0047] The green and energy-saving door and window structure of Embodiment 1 of this invention uses a drawer-type double-sided sliding mechanism to connect the various retractable strips, achieving rigid stacking and retraction of the photovoltaic panels. When the photovoltaic panels are retracted into the shading component storage area, the fixed window looks no different from an ordinary door and window, with an open view and sufficient indoor lighting. When the photovoltaic panels are unfolded, they are sequentially spliced ​​together to form a whole shading component, blocking the light transmission path of the fixed window, greatly reducing the amount of light entering the room, alleviating the workload of indoor cooling equipment, and each photovoltaic panel generates electricity with the help of sunlight to provide power for indoor electrical facilities, further achieving the purpose of energy saving.

[0048] Example 2:

[0049] The following is combined Figures 5-9 The green and energy-saving door and window structure of Embodiment 2 of the present invention is described. Figure 5 A schematic diagram of the winding assembly in Embodiment 2 is shown; the structure of other parts is the same as in Embodiment 1.

[0050] Example 2, based on Example 1, proposes another winding assembly 500, including multiple winding slides slidably connected in sequence, namely a first winding slide 501, a second winding slide 502, a third winding slide 503, a fourth winding slide 504, and a fifth winding slide 505. Each winding slide acts as an independent support connected to the edge of the photovoltaic panel 400, such as... Figure 9 As shown, the connection method of each winding slide is the same as that of the winding slide in Embodiment 1. The difference is that in this embodiment, the winding slide is changed from two sub-slides in Embodiment 1 to only one single slide, which reduces the thickness of the entire winding assembly 500 by half. Furthermore, in this embodiment, the large gear 507 is replaced by a gear assembly 508, specifically, as shown... Figure 6 and Figure 7As shown, the gear assembly 508 includes a first driven gear 50801, a second driven gear 50802, a third driven gear 50803, a fourth driven gear 50804, and a fifth driven gear 50805 respectively meshing with a first winding slide 501, a second winding slide 502, a third winding slide 503, a fourth winding slide 504, and a fifth winding slide 505. It also includes a detachable driving gear 510 that meshes with each driven gear. The driving gear 510 moves along each driven gear... The gears are arranged in a sliding direction on the drive shaft of the take-up motor 506 and are connected to the drive shaft for transmission. When the drive gear 510 slides on the drive shaft, it sequentially meshes with the first driven gear 50801, the second driven gear 50802, the third driven gear 50803, the fourth driven gear 50804, and the fifth driven gear 50805, thereby driving each driven gear in turn. At the same time, each driven gear rotates at intervals on the same shaft and can rotate freely along the circumference of the shaft. In this embodiment, a telescopic module is also provided between the take-up motor 506 and the drive gear 510. The telescopic module is driven by the take-up motor 506 and can extend and retract along the axial direction (length direction) of the drive shaft of the take-up motor 506, thereby driving the drive gear 510 to move along the axial direction of the drive shaft. It achieves sequential engagement with the first driven gear 50801, the second driven gear 50802, the third driven gear 50803, the fourth driven gear 50804, and the fifth driven gear 50805 respectively.

[0051] Further optimize the plan, such as Figure 8 As shown, a slide rod 509 connected to the telescopic module is provided on the side of the drive gear 510 away from the winding motor 506. The slide rod 509 is coaxial with the drive shaft. The slide rod 509 is hollow inside and does not affect the rotation of the drive shaft. One end of the slide rod 509 is connected to one side of the drive gear 510 through a bearing, and the other end passes through the window frame 600 and is circumferentially limited to the window frame 600. Locking teeth 50901 are raised on the rod surface of the slide rod 509 near each driven gear to lock each driven gear, thereby fixing the corresponding winding slide bar, replacing the permanent magnet 700 in Embodiment 1.

[0052] Further optimize the plan, such as Figure 10 As shown, in this embodiment, each winding slide is fixed at the top by a hook 800, thereby replacing the permanent magnet 700 in embodiment 1. The hook 800 is located on the front of the winding slide and engages with the upper teeth 5002. Multiple hooks 800 are rotatably connected to the inner side of the window frame 600 via a shaft (not shown in the figure). Each hook 800 is provided with a torsion spring 801 at the connection position between it and the shaft. Under the action of the torsion spring 801, the hook 800 protrudes towards the winding slide and can support the entire light-blocking assembly from the bottom of the teeth 5002.

[0053] The beneficial effects of this embodiment 2:

[0054] Compared to Example 1, the winding assembly of this structure occupies less space and can install more layers of winding slides, thereby installing more photovoltaic panels. The disadvantage is that the gear assembly of this structure is relatively more complex and has higher requirements for the precision and stability of the transmission mechanism.
