Description

Technical Field

[0001] The present invention belongs to the field of intelligent windows, and particularly relates to a window power generation structure and an intelligent color-changing window. Background Art

[0002] It is estimated that building energy consumption accounts for about 30% of the total social energy consumption and shows an increasing trend year by year. Therefore, promoting building energy conservation and energy-saving renovation of existing buildings has become the focus of China's energy conservation and emission reduction and sustainable development.

[0003] Windows are the main channels for heat exchange between buildings and the outside world. It is estimated that about 50% of heat exchange occurs through windows. Moreover, as customers' requirements for the decoration, intelligence, and energy conservation of buildings continue to increase, and the market expands and reforms continuously, the innovation of glass windows emerges in an endless stream. Among them, electrochromic glass windows are a relatively popular and trendy type of intelligent glass windows in recent years. They are made by sandwiching an electrochromic film in the middle of the glass window and utilizing the phenomenon that the color and transparency of the electrochromic film can change stably and reversibly under the action of an external electric field. However, existing electrochromic glass windows can only be powered externally or charged via radio during use, resulting in high energy consumption and being less environmentally friendly. If energy is absorbed and generated electricity through an external power supply device such as a solar photovoltaic panel, additional installation locations are required, thereby reducing the space utilization rate.

[0004] In the patent document with the application number "CN201821499544.7", a wireless charging electrochromic window is disclosed, which includes an outer window frame, an electrochromic glass, and a window sash for connecting the outer window frame and the electrochromic glass, and a wireless charging component is provided on the window sash. This comparative document applies wireless charging technology to electrochromic glass windows. When using wireless connection, energy can be remotely transmitted without the need to reserve wires, making control more convenient. However, although this comparative document solves the problem of energy transmission, the way of obtaining energy is still to draw power from a fixed power source, and there is no self-power generation device to supply power to the window. Therefore, the problems of high energy consumption and environmental unfriendliness are still not solved.

[0005] The disclosure of the above background art content is only used to assist in understanding the inventive concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background art should not be used to evaluate the novelty and creativity of this application. Summary of the Invention

[0006] The purpose of the present invention is to provide a window power generation structure and an intelligent color-changing window, so as to overcome the defects of existing electrochromic windows being insufficiently energy-saving and environmentally friendly and the low space utilization rate caused by adding additional power supply devices.

[0007] To achieve the above object, the present invention provides a window power generation structure, including a window frame, in which glass is embedded. The characteristics are as follows: Fixed power generation components and movable power generation components are respectively arranged on the frame of the window frame; the fixed power generation components include a fixed lens component and a fixed thermoelectric power generation sheet component that are opposite in position, and the glass is sandwiched between the fixed lens component and the fixed thermoelectric power generation sheet component; the movable power generation components include a sliding seat, on which there are an oppositely arranged movable lens component and a movable thermoelectric power generation sheet component that can elastically float, and the glass is sandwiched between the movable lens component and the movable thermoelectric power generation sheet component; the sliding seat can slide along the frame of the window frame.

The first spring can drive the second lens frame to elastically approach the glass, and the second lens is installed on the second lens frame; a first guiding surface is arranged on the first lens frame, and a second guiding surface is arranged on the second lens frame. When the sliding seat slides to the position of the fixed power generation component, the first guiding surface can contact the second guiding surface so that the second lens frame moves away from the glass and is superposed outside the first lens frame.

[0008] Preferably, in the above technical solution, both the first lens and the second lens are Fresnel lenses.

[0009] Preferably, in the above technical solution, the fixed thermoelectric power generation sheet assembly includes a first power generation sheet and a first power generation sheet seat. The first power generation sheet seat is fixedly installed on the window frame. The first power generation sheet is fixedly installed on one side of the first power generation sheet seat and faces the glass. On the other side of the first power generation sheet seat, there are several first heat dissipation fins. The movable thermoelectric power generation sheet assembly includes a second power generation sheet and a second power generation sheet seat. The second power generation sheet seat is slidably arranged on the second wheel shaft. A second spring is sleeved on the second wheel shaft. The second spring can drive the second power generation sheet seat to elastically approach the glass. The second power generation sheet is fixedly installed on one side of the second power generation sheet seat and faces the glass. On the other side of the second power generation sheet seat, there are several second heat dissipation fins.

[0010] Preferably, in the above technical solution, the positions of the first heat dissipation fins and the second heat dissipation fins correspond to each other. When the ends of the first power generation sheet seat and the second power generation sheet seat are connected to each other, the ends of the first heat dissipation fins and the second heat dissipation fins can also be connected to each other.

[0011] Preferably, in the above technical solution, one end of the first power generation sheet seat is provided with a third guiding surface, and one end of the second power generation sheet seat is provided with a fourth guiding surface. When the sliding seat slides to the fixed power generation assembly, the third guiding surface can contact the fourth guiding surface so that the second power generation sheet seat moves away from the glass and is stacked outside the first power generation sheet seat.

[0012] Preferably, in the above technical solution, the linkage part includes a pulley and a steel cable. There are multiple pulleys, and the pulleys are rotatably arranged at the corners of the window frame. The middle part of the steel cable bypasses the pulleys and is tightened. The two ends of the steel cable are respectively connected to two adjacent sliding seats.

[0013] On the other hand, to achieve the above object, the present invention also provides an intelligent color-changing window, which includes the above-mentioned window body power generation structure. The glass is an electrochromic glass, and it further includes a controller. The controller is electrically connected to the electrochromic glass, the fixed thermoelectric power generation sheet assembly, and the movable thermoelectric power generation sheet assembly.

[0014] Compared with the existing technology, the present invention has the following beneficial effects:

[0015] 1. In the window power generation structure of the present invention, a fixed power generation component and a movable power generation component are installed on the window frame. The lens component in the power generation component focuses sunlight on the thermoelectric power generation sheet component, so that light energy can be converted into electric energy to supply power to the electrochromic glass. Moreover, all the movable power generation components can slide and fold onto the fixed power generation component simultaneously through the linkage part, improving the space utilization rate of the power supply device and making the window have a larger light transmittance after folding.

[0016] 2. A first guiding surface is provided on the first lens frame of the present invention, and a second guiding surface is provided on the second lens frame. When the movable power generation component approaches the fixed power generation component, through the guiding function of the first guiding surface and the second guiding surface, the second lens frame can be guided and stacked outside the first lens frame.

[0017] 3. The first lens and the second lens in the present invention are both Fresnel lenses, which can not only increase the amount of light collection but also reduce the thickness of the lens, saving the installation space.

[0018] 4. First heat dissipation fins for heat dissipation are respectively provided on the first power generation sheet seat and the second power generation sheet seat of the present invention, which can improve the heat dissipation effect of the thermoelectric power generation sheet. In winter, the heat dissipated by the heat dissipation fins can maintain the temperature around the intelligent window, thus playing a role in preventing the glass from frosting to a certain extent.

[0019] 5. A third guiding surface and a fourth guiding surface are respectively provided on the first power generation sheet seat and the second power generation sheet seat of the present invention. When the movable power generation component approaches the fixed power generation component, through the guiding function of the third guiding surface and the fourth guiding surface, the second power generation sheet seat can be guided and stacked outside the first power generation sheet seat.

[0020] 6. When the movable power generation component moves and is stored towards the fixed power generation component, the second lens is superimposed outside the first lens, which can move the original focal length of the first lens towards the direction of the first lens, move the focus away from the first power generation sheet, thus preventing the heat on the first power generation sheet from being focused for a long time, preventing overheating, and reducing the risk of fire.

[0021] 7. The linkage part in the present invention includes pulleys and steel cables, which can drive other sliding seats to slide synchronously when adjusting any one sliding seat, facilitating adjustment. Moreover, the pulley and steel cable structure has less structural space, is easy to install and maintain.

[0022] 8. In the present invention, multiple first wheel shafts and second wheel shafts are arranged in parallel in the wheel seat and pass through the wheel groove for fitting installation with the wheel groove, which can improve the balance of the wheel seat. Moreover, the second roller is limited by a card. The card has a relatively thin thickness, which can not only play the role of limiting the second roller but also save the thickness space, enabling the second spectacle frame and the second power generation piece seat to be closer to the glass surface under the action of the spring and preventing interference between the two and the limiting parts.

[0039] As Figures 1 to 6As shown in the figure, the window power generation structure in this embodiment includes: a window frame 100, a sliding groove 110, glass 200, a fixed power generation component 300, a fixed lens component 310, a first lens frame 311, a first lens 312, a first guiding surface 313, a fixed thermoelectric power generation sheet component 320, a first power generation sheet seat 321, a first heat sink 322, a third guiding surface 323, a movable power generation component 400, a movable lens component 410, a second lens frame 411, a second lens 412, a second guiding surface 413, a first spring 414, a movable thermoelectric power generation sheet component 420, a second power generation sheet seat 421, a second spring 422, a second heat sink 423, a fourth guiding surface 424, a sliding seat 430, a first wheel shaft 431, a second wheel shaft 432, a seat plate 433, a first roller 434, a second roller 435, a card 436, a linkage part 500, a pulley 510, and a steel cable 520.

[0040] The glass 200 is embedded in the window frame 100. The glass 200 can be single-layer, double-sided or laminated glass 200. The fixed power generation component 300 and the movable power generation component 400 are respectively installed on the frame of the window frame 100.

[0041] Among them, the fixed power generation component 300 includes a fixed lens component 310 and a fixed thermoelectric power generation sheet component 320 that are opposite in position. The glass 200 is located between the fixed lens component 310 and the fixed thermoelectric power generation sheet component 320. The fixed lens component 310 includes a first lens frame 311 and a first lens 312. The first lens frame 311 is fixedly installed on the window frame 100 by bolts, and the first lens 312 is installed on the first lens frame 311. The fixed thermoelectric power generation sheet component 320 includes a first power generation sheet and a first power generation sheet seat 321. The first power generation sheet seat 321 is fixedly installed on the window frame 100 by bolts. The first power generation sheet is fixedly installed on the side of the first power generation sheet seat 321 facing the glass 200. On the other side of the first power generation sheet seat 321, multiple first heat sinks 322 are vertically arranged, and there is a certain gap between each first heat sink 322. The first lens 312 is a Fresnel lens. When sunlight passes through the first lens 312, the focus of the light just falls on the first power generation sheet. The first power generation sheet is a semiconductor thermoelectric power generation sheet, so electric energy can be generated for power generation.

[0042] In addition, the movable power generation component 400 includes a sliding seat 430, a movable lens component 410, and a movable thermoelectric power generation sheet component 420. A sliding groove 110 is formed on the frame of the window frame 100. The sliding seat 430 is composed of two seat plates 433. Two first wheel shafts 431 and two second wheel shafts 432 are vertically connected between the two seat plates 433. The two first wheel shafts 431 are located between the two second wheel shafts 432. The first wheel shafts 431 and the second wheel shafts 432 both horizontally pass through the sliding groove 110. A rotatable first roller 434 is installed on the first wheel shaft 431. The first roller 434 can be stuck in the sliding groove 110 and can roll in the sliding groove 110. A rotatable second roller 435 is installed on the second wheel shaft 432. The second roller 435 is limited on the second wheel shaft 432 by a card 436. The second roller 435 can be stuck in the sliding groove 110 and can roll in the sliding groove 110. The movable lens component 410 and the movable thermoelectric power generation sheet component 420 are simultaneously installed on the second wheel shaft 432. The glass 200 is located between the movable lens component 410 and the movable thermoelectric power generation sheet component 420. The movable lens component 410 includes a second lens frame 411 and a second lens 412. The second lens frame 411 is sleeved on the second wheel shaft 432 in a slidable manner. A first spring 414 is also sleeved on the second wheel shaft 432. The first spring 414 is located between the seat plate 433 and the second lens frame 411. The first spring 414 can drive the second lens frame 411 to elastically approach the glass 200. The second lens 412 is installed on the second lens frame 411. The movable thermoelectric power generation sheet component 420 includes a second power generation sheet and a second power generation sheet seat 421. The second power generation sheet seat 421 is sleeved on the second wheel shaft 432 in a slidable manner. A second spring 422 is sleeved on the second wheel shaft 432. The second spring 422 is located between the seat plate 433 and the second power generation sheet seat 421 and can drive the second power generation sheet seat 421 to elastically approach the glass 200. The second power generation sheet is fixedly installed on the side of the second power generation sheet seat 421 facing the glass 200. On the other side of the second power generation sheet seat 421, multiple second heat dissipation fins 423 are vertically arranged. There is a certain gap between the second heat dissipation fins 423. The position of the first heat dissipation fin 322 corresponds to that of the second heat dissipation fin 423. When the ends of the first power generation sheet seat 321 and the second power generation sheet seat 421 are connected to each other, the ends of the first heat dissipation fin 322 and the second heat dissipation fin 423 can also be connected to each other, thereby forming a heat dissipation fin structure with a longer length, so as to increase the heat dissipation effect.

[0043] More specifically, an inclined first guiding surface 313 is provided at one end of the first lens frame 311 facing the second lens frame 411, and an inclined second guiding surface 413 is provided at one end of the second lens frame 411 facing the first lens 312. When the sliding seat 430 slides to the fixed power generation assembly 300, the first guiding surface 313 can contact the second guiding surface 413 so that the second lens frame 411 moves away from the glass 200 and is superimposed on the outside of the first lens frame 311; a third guiding surface 323 is provided at one end of the first power generation sheet seat 321, and a fourth guiding surface 424 is provided at one end of the second power generation sheet seat 421. When the sliding seat 430 slides to the fixed power generation assembly 300, the third guiding surface 323 can contact the fourth guiding surface 424 so that the second power generation sheet seat 421 moves away from the glass 200 and is superimposed on the outside of the first power generation sheet seat 321, thereby forming a storage state.

[0044] The sliding seats 430 are connected by a linkage portion 500. The linkage portion 500 can make the sliding seats 430 on the frame of the window frame 100 move synchronously. The linkage portion 500 includes pulleys 510 and a steel cable 520; there are multiple pulleys 510, and each pulley 510 is rotatably installed at the corner of the window frame 100. The middle of the steel cable 520 bypasses the pulley 510 and is tightened. The two ends of the steel cable 520 are respectively connected to the seat plates 433 of two adjacent sliding seats 430.

[0045] In use, when solar energy needs to be absorbed for power generation, the operator moves any one of the movable power generation components 400 away from the fixed power generation component 300, causing the second lens frame 411 and the second power generation sheet base 421 to elastically approach the glass 200 simultaneously, so that the second lens frame 411 and the first lens frame 311 are flush with each other, and the second power generation sheet base 421 and the first power generation sheet base 321 are flush with each other. At this time, sunlight is focused after passing through the first lens 312 and the second lens 412, and the focus falls on the first power generation sheet and the second power generation sheet. Due to the inherent characteristics of the semiconductor thermoelectric generation sheet, a power generation effect is generated; when power generation is not required, any one of the movable power generation components 400 is moved again away from the fixed power generation component 300. Due to the action of the linkage part 500, all the movable power generation components 400 move synchronously. At this time, the second lens frame 411 will move and be superimposed above the first lens frame 311, so that the first lens 312 and the second lens 412 are also superimposed on each other, and the second power generation sheet base 421 will move and be superimposed above the first power generation sheet base 321. When the first lens 312 and the second lens 412 are superimposed on each other, the focus of sunlight passing through the superimposed lenses will move forward and move away from the first power generation sheet, thus effectively preventing the temperature rise of the power generation sheet and protecting the entire device; and the movable power generation components 400 can also vacate most of the light-transmitting area of the glass 200 for light transmission after being displaced, increasing the light transmittance of the intelligent window. Embodiment 2

[0046] This embodiment discloses an intelligent color-changing window, which includes the window body power generation structure in the above embodiment, wherein the glass 200 is a double-layer electrochromic glass structure. In addition, it further includes a controller, which is electrically connected between the electrochromic glass, the fixed thermoelectric generation sheet assembly 320 and the movable thermoelectric generation sheet assembly 420.

[0047] Among them, the controller includes a main control module, a lithium battery, a relay (including an A switch handle, a B normally closed port, and a C normally open port), a DC-DC module and a USB boost voltage regulation module. The USB boost voltage regulation module is connected to the thermoelectric generation sheet, and the USB boost voltage regulation module can achieve a stable 5V voltage output and charge the lithium battery through a Micro-USB data cable. The positive output of the lithium battery is connected to the input port 1 (IN+) of the DC-DC power conversion module, the negative output of the lithium battery is connected to the thermal relay B port of the main control module, and the other input port (IN-) of the DC-DC power conversion module is connected to the thermal relay A port of the main control module. The two output terminals of the DC-DC should be respectively connected to the two power control ports of the electrochromic glass layer correspondingly, and the output voltage of the DC-DC module after boosting can meet the working consumption of the electrochromic glass. The relay is integrated in the main control module.

[0048] In summary, in the window power generation structure and the intelligent color-changing window of the present invention, the lens assembly in the power generation assembly focuses sunlight on the thermoelectric power generation sheet assembly so as to convert light into electric energy to supply power to the electrochromic glass; and all the movable power generation assemblies 400 can also slide and fold onto the fixed power generation assembly 300 simultaneously through the linkage part 500, improving the space utilization rate of the power supply device and making the window have a greater light transmittance after folding.
