Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a photovoltaic louver louver electrification structure. Background Technology

[0002] Photovoltaic blinds are a type of smart blind that generates electricity, with built-in solar cells. Each photovoltaic blind has a power probe installed at both ends, and copper strips are fixed on both sides of the window frame. The circuit is connected by the contact between the power probe and the copper strip.

[0003] As per the instruction manual Figure 1 As shown, existing photovoltaic louvers 1 are typically rotatable and slide up and down within a slot in the window frame 2. A lever 3 is installed within the slot, and a copper strip 5 is secured to the lever 3 via a rubber strip 6. A current-carrying probe 4 on the photovoltaic louver contacts the copper strip 5, thus connecting the circuit. However, during the up-and-down movement and rotation of the photovoltaic louver 1, the current-carrying probe 4 remains in constant contact with the copper strip 5, inevitably causing wear on both the probe 4 and the copper strip 5, drastically shortening the product's lifespan.

[0004] Therefore, in view of the problems existing in the above-mentioned background technology, how to design a photovoltaic louver energizing structure that avoids wear between the energizing probe and the copper strip when the photovoltaic louver moves up and down or rotates is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a photovoltaic louver energizing structure that enables the energizing probe and the copper strip to remain separated during movement, thereby avoiding frictional wear of the photovoltaic louver during movement and improving the product's service life.

[0006] To achieve the above objectives, this application provides a photovoltaic louver energized structure, which includes photovoltaic louvers disposed between window frames and a lever embedded in the window frame and located at the end of the photovoltaic louvers. The photovoltaic louvers and the lever are spaced apart. An energizing probe is disposed at the end of the photovoltaic louvers. A copper strip is disposed on the end face of the lever facing the photovoltaic louvers. The energizing probe abuts against and is electrically connected to the copper strip.

[0007] The side of the lever facing away from the photovoltaic louver is provided with a fixing plate, which is connected to the window frame. An electromagnet is provided on the end face of the fixing plate facing the lever, and an iron block is provided on the end face of the lever facing the fixing plate. The electromagnet and the iron block are spaced apart. When energized, the electromagnet attracts the iron block, which drives the copper strip on the lever away from the energized probe and keeps the copper strip spaced apart from the energized probe.

[0008] Preferably, the fixed plate is provided with a guide shaft that passes through itself and through the paddle, the paddle is slidably disposed along the axial direction of the guide shaft, and a limiting pin is provided at the end of the guide shaft opposite to the fixed plate, the head of the limiting pin being located at the end face of the paddle opposite to the fixed plate, for limiting the paddle.

[0009] Preferably, there are multiple guide shafts, and each guide shaft is fitted with a spring on its outer periphery. The two ends of the spring abut against the fixing plate and the lever, respectively, to provide the lever with an elastic force away from the fixing plate.

[0010] Preferably, a limiting ring and a retaining ring are provided on the outer periphery of any of the guide shafts. The limiting ring and the retaining ring abut against the two end faces of the fixing plate, respectively, to axially limit the guide shaft on the fixing plate.

[0011] Preferably, any of the guide shafts is perpendicular to both the paddle and the fixing plate.

[0012] Preferably, the fixing plate is snapped into the window frame.

[0013] Preferably, the iron block is fixed to the end face of the lever by a fastener.

[0014] Preferably, there are multiple photovoltaic louvers, and each photovoltaic louver is provided with an electrical probe at its end, and each electrical probe abuts against and is electrically connected to the copper strip.

[0015] Preferably, the lever is arranged along the edge of the window frame, and the copper strip is arranged in the same direction and length as the lever.

[0016] Preferably, a rubber strip of equal length is snapped onto the end face of the lever facing the energized probe, the rubber strip being used to snap onto the copper strip, and the copper strip being unobstructed on the end face facing the energized probe.

[0017] Compared to the aforementioned background technology, this application provides a photovoltaic louver energized structure. This structure utilizes the magnetic attraction principle of an electromagnet and an iron block, causing the lever to move towards the electromagnet along with the iron block, thereby causing the copper strip to separate from the energized probe. After separation, the photovoltaic louver can move up and down and rotate without friction, thus reducing frictional wear between the energized probe and the copper strip. Specifically, a fixing plate is provided on the side of the lever away from the photovoltaic louver, and the fixing plate is mounted on the window frame. An electromagnet is provided on the end face of the fixing plate, and an iron block is provided on the end face of the lever. Before the electromagnet is energized, the electromagnet and the iron block are spaced apart. After the electromagnet is energized, the electromagnet can attract the iron block, causing the two to adhere together, thereby moving the copper strip on the lever away from the energized probe, achieving the effect of separation and avoiding friction. Of course, after the electromagnet is de-energized, the copper strip can reset and hold against the energized probe, maintaining electrical connection and forming a normal conductive circuit. Therefore, the photovoltaic louver energizing structure designed in the above manner can keep the energizing probe and the copper strip separated during movement, avoiding frictional wear of the photovoltaic louver during movement and improving product lifespan.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] As per the instruction manual Figures 2 to 5 As shown, in this embodiment, a photovoltaic louver energized structure is provided. The structure includes a photovoltaic louver 1 disposed between window frames 2 and a lever 3 embedded in the window frame 2 and located at the end of the photovoltaic louver 1. Similar to ordinary louvers, the photovoltaic louver 1 is also located between window frames 2 and can be raised or lowered, as well as rotated. The difference is that the photovoltaic louver 1 has a built-in solar cell that can convert solar energy into electrical energy and conduct the electrical energy to the copper strip 5 for energy storage through the energized probe 4 at its end.

[0028] The aforementioned lever 3 is located at the end of the photovoltaic louver 1 and is spaced apart from it. Generally speaking, a groove can be opened on the inner wall of the window frame 2, and the lever 3 can be placed inside the groove to improve the overall appearance of the photovoltaic louver. In this embodiment, the setting direction of the lever 3 is consistent with the direction of the window frame 2. That is to say, the lever 3 is set along the edge direction of the window frame 2, and the lever 3 has an integral structure, which facilitates the synchronous movement of the upper and lower ends of the lever 3.

[0029] As indicated in the above embodiments, the power-conducting probe 4 needs to conduct electricity, and therefore needs to be electrically connected to the solar cell. Simultaneously, the power-conducting probe 4 is located at the end of the photovoltaic louver 1, facilitating electrical connection with the copper strip 5. Furthermore, the copper strip 5 is disposed on the end face of the lever 3 facing the photovoltaic louver 1, enabling it to abut against the power-conducting probe 4. Moreover, there are no other obstructions on the end face of the copper strip 5 facing the power-conducting probe 4, ensuring that the power-conducting probe 4 can abut and connect with the copper strip 5 at any position during the up-and-down movement of the photovoltaic louver 1.

[0030] It should be noted that a fixing plate 13 is provided on the side of the lever 3 facing away from the photovoltaic louver 1. The fixing plate 13 can be connected to the window frame 2. Based on the above embodiment, the fixing plate 13 can be set in the groove of the window frame 2. Of course, this groove can be set as a through groove, and the fixing plate 13 is fixed in the through groove. In addition, there are many ways to set the above groove, including but not limited to the groove and through groove settings mentioned above. These will not be described in detail here, and all of them are within the protection scope of this application.

[0031] Furthermore, an electromagnet 12 is provided on the end face of the fixed plate 13 facing the lever 3, and an iron block 11 is provided on the end face of the lever 3 facing the fixed plate 13. The electromagnet 12 and the iron block 11 are spaced apart to allow the lever 3 to move so that the copper strip 5 can separate from the energized probe 4. Of course, the electromagnet 12 and the iron block 11 are spaced apart before the electromagnet 12 is energized. After the electromagnet 12 is energized, it can attract the iron block 11, which will drive the copper strip 5 on the lever 3 away from the energized probe and separate the copper strip 5 from the energized probe. After separation, the photovoltaic louver 1 can move up and down and rotate without being affected by the friction between the energized probe 4 and the copper strip 5.

[0032] As can be seen from the above embodiments, this structure utilizes the magnetic attraction principle of electromagnet 12 and iron block 11 to make the lever 3 move towards electromagnet 12 along with iron block 11, thereby causing copper strip 5 to separate from the energized probe 4. After the two are separated, photovoltaic louver 1 can move up and down and rotate without friction, thus reducing frictional wear between the energized probe and copper strip 5. Specifically, a fixing plate 13 is provided on the side of lever 3 away from photovoltaic louver 1. The fixing plate 13 is set on window frame 2. Electromagnet 12 is provided on the end face of fixing plate 13, and iron block 11 is provided on the end face of lever 3. Before electromagnet 12 is energized, electromagnet 12 and iron block 11 are spaced apart. After electromagnet 12 is energized, electromagnet 12 can attract iron block 11, making the two stick together, thereby causing copper strip 5 on lever 3 to move away from energized probe, achieving the effect of separation and avoiding friction.

[0033] Furthermore, to ensure the stability of the lever 3 on the window frame 2 and its smoothness during movement, in this embodiment, the fixing plate 13 is provided with a guide shaft 7 that passes through itself and through the lever 3. The lever 3 can slide axially along the guide shaft 7. A limiting pin 10 is provided at the end of the guide shaft 7 away from the fixing plate 13. Since this end passes through the lever 3, the head of the limiting pin 10 is located on the end face of the lever 3 away from the fixing plate 13. The outer diameter of the head of the limiting pin 10 is larger than the outer diameter of the opening on the lever 3, thus serving to limit the lever 3. Of course, there are various ways to limit the lever 3, not limited to the limiting pin 10 mentioned above. It can be set according to actual needs, and no specific requirements are given here.

[0034] Of course, after the electromagnet 12 is de-energized, the copper strip 5 can reset and abut against the energized probe 4, maintaining electrical connection and thus forming a normal conductive circuit. In this embodiment, the reset of the copper strip 5 can be achieved by the spring 9. It should be noted that, in order to further improve the smoothness of the operation of the lever 3, multiple guide shafts 7 can be set, and a spring 9 is sleeved on the outer periphery of any one of the guide shafts 7. The two ends of the spring 9 abut against the fixed plate 13 and the lever 3 respectively, which can provide the lever 3 with an elastic force away from the fixed plate 13. Of course, other forms of elastic elements can be used to replace the above-mentioned spring 9, which will not be described in detail here, as long as it can play the role of resetting the lever 3.

[0035] In addition, the specific number of guide shafts 7 is not required here. It is sufficient to ensure that the paddle 3 moves smoothly and does not affect the electromagnet 12 adsorbing the iron block 11.

[0036] Since the paddle 3 needs to slide axially on the guide shaft 7, the other end of the guide shaft 7 needs to be fixed to prevent displacement of the guide shaft 7 itself, which would cause it to fail to guide. Therefore, in this embodiment, a limiting ring 14 and a retaining spring 8 are provided on the outer periphery of the guide shaft 7, and the limiting ring 14 and the retaining spring 8 respectively abut against the two end faces of the fixing plate 13, thereby axially limiting the guide shaft 7 on the fixing plate 13. As for the circumferential direction of the guide shaft 7, no limiting is required. Furthermore, in order to facilitate the disassembly and assembly of the guide shaft 7, the retaining spring 8 can be set on the outside of the fixing plate 13, which can facilitate the direct disassembly by the operator. Of course, the specific setting method can be selected according to the actual situation, and no specific limitation is made here. In addition, there are many other ways to limit the axial direction of the guide shaft 7, not limited to the above-mentioned implementation method, which will not be described in detail here, and all of them are within the protection scope of this application.

[0037] To facilitate the movement of the paddle 3, the guide shaft 7 is set perpendicularly to the paddle 3 and the fixing plate 13. The friction between the vertically set guide shaft 7 and the paddle 3 is small, and there will be no jamming or other phenomena during the movement. In other words, the paddle 3 only moves along the axial direction of the guide shaft 7 and does not move in other directions.

[0038] In addition, the fixing plate 13 can be connected to the window frame 2 by snap-fitting with an inner or outer clip, which facilitates the installation and removal of the fixing plate 13. As for its specific setting method, it can be set according to actual needs, and will not be described in detail here.

[0039] Of course, the aforementioned iron block 11 needs to be fixedly connected to the fixing plate 13. This can be done by bolts or other means to ensure a stable connection between the two.

[0040] Typically, a photovoltaic louver can have multiple photovoltaic louvers 1, which collect light energy. Each photovoltaic louver 1 has an electrical probe 4 at its end, and each electrical probe 4 is electrically connected to and abuts against a copper strip 5. The above embodiment indicates that there are no other obstructions on the end face of the copper strip 5 facing the electrical probe 4, satisfying the condition that multiple electrical probes 4 can be electrically connected to the copper strip 5 simultaneously, thus achieving a parallel connection of multiple circuits.

[0041] It should be noted that the setting direction of the lever 3 is consistent with the side edge direction of the window frame 2. That is to say, the lever 3 is set along the side edge of the window frame 2. Similarly, the setting direction of the copper strip 5 is also the same as that of the lever 3, so that the photovoltaic louver 1 can stop at any time during the up and down movement and be electrically connected to the copper strip 5. In addition, since photovoltaic louver windows usually need to be covered with photovoltaic louvers 1 on the window surface, the length of the copper strip 5 can be set to be consistent with the length of the lever 3. Of course, the setting length of the lever 3 and the copper strip 5 can be set according to actual needs, and no restrictions are imposed here.

[0042] Furthermore, a rubber strip 6 of equal length is snapped onto the end face of the lever 3 facing the power probe 4. The rubber block is used to snap onto the copper strip 5, and the end face of the copper strip 5 facing the power probe 4 is not affected by the rubber strip 6. As for the specific setting method, it will not be described in detail here, please refer to the existing technology. In addition, for the specific setting method of other components included in the window, please also refer to the existing technology, and it will not be described in detail here.

[0043] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0044] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
