[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] The area of ​​a photovoltaic solar panel is too large. When it is damaged, the fasteners on the entire panel need to be disassembled to replace the entire panel, which makes the replacement efficiency low and the replacement cost of the entire panel high. At the same time, the panel with an overly large area requires a lot of storage space and transportation space.

[0040] The inventors discovered that an entire solar panel can be divided into multiple small-sized solar panels. These small-sized solar panels can be individually connected to a fixed plate to form a photovoltaic power generation device with the same power generation efficiency as the entire solar panel. Because each small-sized solar panel can be connected to the fixed plate by plugging, if damaged, one or more small-sized solar panels can be removed from the fixed plate and replaced with new small-sized solar panels. This quick and efficient removal and plugging method improves replacement efficiency. Replacing small-sized solar panels can also reduce replacement costs compared to replacing the entire panel. Furthermore, multiple small-sized solar panels can be stacked for storage or transportation, thereby reducing the storage and transportation space requirements of photovoltaic solar panels.

[0041] The present disclosure provides a photovoltaic power generation device, see Figures 1 to 11As shown, the photovoltaic power generation device may include: a fixed plate 1 and a plurality of solar cell panels 2, wherein a plurality of assembly areas 11 and a plurality of first electrical connection parts 12 are provided on one side of the fixed plate 1, and the plurality of first electrical connection parts 12 correspond one-to-one to the plurality of assembly areas 11; the plurality of solar cell panels 2 are respectively plugged into the plurality of assembly areas 11, and are respectively provided with a second electrical connection part 21 adapted to the first electrical connection part 12.

[0042] In other words, the multiple assembly areas 11 on one side of the fixed plate 1 are respectively provided with first electrical connection parts 12, and the multiple solar panels 2 can be respectively plugged into the multiple assembly areas 11, and after plugging, the multiple first electrical connection parts 12 on the fixed plate 1 are respectively electrically connected to the second electrical connection parts 21 on the multiple solar panels 2, and then the multiple first electrical connection parts 12 on the fixed plate 1 can be connected to the power storage device or the power consumption device to store the electric energy generated by the photovoltaic power generation device through the power storage device or consume the electric energy generated by the photovoltaic power generation device through the power consumption device. Here, the size of the solar panel 2 is smaller than the size of the entire battery panel mentioned above (for example, multiple solar panels 2 are multiple small modules divided from the entire battery panel), and are fixed on the fixed plate 1 by plugging. When damage occurs, the damaged one or more small-sized solar panels 2 can be pulled out of the fixed plate 1 and replaced with new solar panels 2. The pulling out and plugging method is fast and efficient, which can shorten the replacement time, improve the replacement efficiency, and thus improve the power generation efficiency. Replacing the small-sized solar panel 2 can reduce the replacement cost compared to replacing the entire battery panel. At the same time, multiple small-sized solar panels 2 can be stacked for storage or transportation, thereby reducing the requirements of the photovoltaic solar panel 2 for storage space and transportation space. The small-sized solar panel 2 is light in weight and small in size, and is easy to carry.

[0043] The fixing plate 1 can be a regular plate structure such as a triangle, rectangle, pentagon, circle, etc., or can be other irregular plate structures, such as: Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 8 The fixed plate 1 shown in the figure is a regular rectangular plate structure; Figure 9 The irregular plate structure shown in FIG is an arc-shaped structure at one end and a quadrilateral structure at the other end. Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figures 8 to 10The arrangement shown in FIG1 may be arranged neatly in multiple rows and columns, but may also be arranged in a divergent manner, or in other arrangements. The first electrical connection portion 12 may be disposed in a groove of the assembly area 11, on a protrusion of the assembly area 11, or on other structures of the assembly area 11. It may be a raised spring, a flat surface, or other structures, and is not specifically limited here.

[0044] The plurality of solar panels 2 are plugged into the plurality of assembly areas 11, which can be the plugging of a part of the solar panel 2 relative to a part of the fixed plate 1, such as the plugging between the first groove 13 and the first protrusion 22, and the plugging between the second groove 23 and the second protrusion 14 described below. It can also be the plugging of the solar panel 2 as a whole relative to the fixed plate 1, such as the mutual plugging of the solar panel 2 and the second limiting structure 16 described below. After the plurality of solar panels 2 are plugged into the plurality of assembly areas 11, the second electrical connection portion 21 of the solar panel 2 can be electrically connected to the first electrical connection portion 12 of the fixed plate 1. The first electrical connection portion 12 and the second electrical connection portion 21 can be connected simultaneously during the plugging, such as: see Figure 3 and Figure 4 As shown, the first electrical connection portion 12 is arranged on the side wall of the first groove 13, and the second electrical connection portion 21 is arranged on the side wall of the first protrusion 22. When the side wall of the first protrusion 22 is inserted into the first groove 13 along the side wall of the first groove 13, the second electrical connection portion 21 and the first electrical connection portion 12 contact each other to be electrically connected. Alternatively, the first electrical connection portion 12 and the second electrical connection portion 21 complete the electrical connection after insertion. For example, after the solar cell panel 2 is inserted into the insertion space 161 defined by the second limiting structure 16, the solar cell panel 2 contacts the electrical connection area to complete the electrical connection. The shapes, sizes, etc. of different solar cells 2 can be consistent or inconsistent. The size and number of solar cells 2 can be set according to the size of the fixing plate 1 to improve the flexibility of the installation and adapt to various lighting conditions and installation environments.

[0045] Here, a frame can be provided on a circle of the edge of the fixing plate 1 corresponding to the assembly area 11. When the solar panel 2 is connected to the assembly area 11, it can be recessed, raised or flush with the frame so that the frame can protect the thickness surface of the solar panel 2 adjacent to the frame position.

[0046] In some embodiments, see Figures 1 to 5As shown, the fixing plate 1 has a first recessed groove 13, which is provided with a first electrical connection portion 12. The solar panel 2 has a first protrusion 22 on its protrusion, which is provided with a second electrical connection portion 21. The first protrusion 22 is inserted into the first recess 13, so that the solar panel 2 is inserted into the corresponding assembly area 11, and the first electrical connection portion 12 and the second electrical connection portion 21 are connected to each other. In other words, when the first protrusion 22 of the solar panel 2 is inserted into the first recess 13 on the fixing plate 1, not only is the plug-in connection between the solar panel 2 and the fixing plate 1 achieved, but also the electrical connection between the first electrical connection portion 12 and the second electrical connection portion 21 is achieved.

[0047] Here, see Figure 3 and Figure 4 As shown, the first electrical connection portion 12 can be arranged on the side wall of the first groove 13, and the second electrical connection portion 21 can be arranged on the peripheral side of the first protrusion 22. In this way, when the first protrusion 22 on the solar cell panel 2 is inserted into the first groove 13 on the fixing plate 1, the first electrical connection portion 12 and the second electrical connection portion 21 are positioned relative to each other and contact each other to be electrically connected to each other; the first electrical connection portion 12 can also be arranged on the inner bottom wall of the first groove 13, and the second electrical connection portion 21 is arranged on the free end surface of the first protrusion 22. In this way, when the first protrusion 22 on the solar cell panel 2 is inserted into the first groove 13 on the fixing plate 1, the first electrical connection portion 12 and the second electrical connection portion 21 are positioned relative to each other and contact each other to be electrically connected to each other. The first electrical connection portion 12 may be a spring sheet, and the second electrical connection portion 21 may be a planar contact area. When the first electrical connection portion 12 and the second electrical connection portion 21 are positioned relative to each other and in contact with each other, the spring sheet of the first electrical connection portion 12 is squeezed by the planar contact area of ​​the second electrical connection portion 21 to achieve electrical connection between the first electrical connection portion 12 and the second electrical connection portion 21. Alternatively, the first electrical connection portion 12 may be a planar contact area, and the second electrical connection portion 21 may also be a planar contact area. When the first electrical connection portion 12 and the second electrical connection portion 21 are positioned relative to each other, The planar contact area of ​​the first electrical connection part 12 and the planar contact area of ​​the second electrical connection part 21 contact each other to achieve electrical connection between the first electrical connection part 12 and the second electrical connection part 21; alternatively, the first electrical connection part 12 may be a planar contact area, and the second electrical connection part 21 may be a spring. When the first electrical connection part 12 and the second electrical connection part 21 are positioned relative to each other and contact each other, the spring of the second electrical connection part 21 is squeezed by the planar contact area of ​​the first electrical connection part 12 to achieve electrical connection between the first electrical connection part 12 and the second electrical connection part 21.

[0048] In some embodiments, see Figures 6 to 8As shown, the fixing plate 1 has a second protrusion 14 on its convex portion, which is provided with a first electrical connection portion 12; the solar panel 2 has a second groove 23 on its concave portion, which is provided with a second electrical connection portion 21. The second protrusion 14 is inserted into the second groove 23, so that the solar panel 2 is inserted into the corresponding assembly area 11, and the first electrical connection portion 12 and the second electrical connection portion 21 are connected to each other. This arrangement is opposite to that of the previous embodiment, and the detailed description of the previous embodiment can be referred to and will not be repeated here.

[0049] One plug-in method is: a first groove 13 is provided on the fixing plate 1, and a first protrusion 22 is provided on the solar panel 2. The first protrusion 22 and the first groove 13 are plugged together to connect the solar panel 2 to the fixing plate 1. Another plug-in method is: a second protrusion 14 is provided on the fixing plate 1, and a second groove 23 is provided on the solar panel 2. The second protrusion 14 and the second groove 23 are plugged together to connect the solar panel 2 to the fixing plate 1. Based on these two plug-in methods, in order to reduce the probability of the first protrusion 22 and the second protrusion 14 breaking under the action of gravity on the solar panel 2, in some embodiments, the surface of the fixing plate 1 provided with the assembly area 11 is further provided with a plurality of first limiting structures 15 corresponding to the plurality of assembly areas 11. When the solar panel 2 is plugged into the corresponding assembly area 11, the first limiting structures 15 limit the position of the solar panel 2 at least in two positions opposite to each other. That is to say, after the solar panel 2 is plugged into the corresponding assembly area 11, the solar panel 2 is also limited by the first limiting structure 15, and the limiting method is that the first limiting structure 15 limits at least two positions of the solar panel 2 that are opposite to each other, so that the solar panel 2 can be supported to make the solar panel 2 more firmly fixed on the fixing plate 1; at the same time, the first limiting structure 15 forms a guiding structure for the solar panel 2 to guide during the process of plugging the solar panel 2 into the fixing plate 1.

[0050] The thickness of the first limiting structure 15 can be less than the thickness of the solar panel 2, so that part of the thickness surface of the solar panel 2 is exposed, so that the exposed surface can be used to pull out the solar panel 2, and the material used for the first limiting structure 15 can be reduced to reduce the manufacturing cost; it can also be equal to the thickness of the solar panel 2, so that the first limiting structure 15 is flush with the solar panel 2, thereby making the side of the multiple solar panels 2 on the photovoltaic power generation device facing away from the fixed plate 1 and the side of the multiple first limiting structures 15 facing away from the fixed plate 1 on the same plane, thereby improving the visual effect of the photovoltaic power generation device.

[0051] In some embodiments, the first limiting structure 15 can be set in a circle along the boundary of the assembly area 11, that is, a ring-shaped structure. When the solar panel 2 is plugged into the fixed plate 1, the surface of a circle of the solar panel 2 abuts against the first limiting structure 15 to achieve the limitation and support of the solar panel 2.

[0052] In some embodiments, see Figure 1 、 Figure 5 、 Figure 8 and Figure 9 As shown, the first limiting structure 15 may include: a first limiting portion 151 and a second limiting portion 152. The first limiting portion 151 has a first bend, and the second limiting portion 152 has a second bend. The inner surface of the first bend and the inner surface of the second bend are opposite to each other. The solar panel 2 is inserted into the corresponding assembly area 11, and the inner surface of the first bend and the inner surface of the second bend respectively abut against two opposite locations in the thickness direction of the solar panel 2 inserted into the fixing plate 1. The inner surface of the first bend can be a right-angle bend, an arc bend, or a bend of other shapes, which can be adapted to the position corresponding to the first bend on the solar panel 2; the inner surface of the second bend can be a right-angle bend, an arc bend, or a bend of other shapes, which can be adapted to the position corresponding to the second bend on the solar panel 2. The adaptive arrangement can better abut the solar panel 2 and limit it. The first bend and the second bend enable the first limiting portion 151 and the second limiting portion 152 to limit the first and second positions opposite to each other of the solar panel 2, and to limit the third and fourth positions opposite to each other of the solar panel 2, and the first position and the third position are connected, and the second position and the fourth position are connected, so that the first limiting structure 15 can limit the solar panel 2 more securely.

[0053] In one example, see Figure 1 、 Figure 5 、 Figure 8 and Figure 9 As shown, the inner surface of the first bend of the first limiting portion 151 is a right-angled bend, and the inner surface of the second bend of the second limiting portion 152 is also a right-angled bend. The solar panel 2 is rectangular and has a first side surface, a second side surface, a third side surface, and a fourth side surface connected sequentially in its thickness direction. In this way, the first limiting portion 151 can abut the first side surface (corresponding to the first position above) and the second side surface (corresponding to the third position above) of the solar panel 2, and the second limiting portion 152 can abut the third side surface (corresponding to the second position above) and the fourth side surface (corresponding to the fourth position above) of the solar panel 2, thereby limiting each side surface of the solar panel 2, so that the solar panel 2 is more firmly fixed to the fixing plate 1.

[0054] In some embodiments, at least one of the first limiting portion 151 and the second limiting portion 152 is movably connected to the fixing plate 1 so that the first limiting portion 151 and the second limiting portion 152 can move closer to or farther away from each other. The first limiting portion 151 may be fixedly connected to the fixed plate 1, and the second limiting portion 152 may be movably connected to the fixed plate 1 so as to be able to move closer to the first limiting portion 151 or move away from the first limiting portion 151, thereby realizing that the first limiting portion 151 and the second limiting portion 152 are close to or away from each other; it may also be that the second limiting portion 152 is fixedly connected to the fixed plate 1, and the first limiting portion 151 is movably connected to the fixed plate 1 so as to be able to move closer to the second limiting portion 152 or move away from the second limiting portion 152, thereby realizing that the first limiting portion 151 and the second limiting portion 152 are close to or away from each other; it may also be that the first limiting portion 151 is movably connected to the fixed plate 1 so as to be able to move closer to the second limiting portion 152 or move away from the second limiting portion 152, and the second limiting portion 152 is movably connected to the fixed plate 1 so as to be able to move closer to the first limiting portion 151 or move away from the first limiting portion 151, thereby realizing that the first limiting portion 151 and the second limiting portion 152 are close to or away from each other.

[0055] In one example, a sliding track may be provided in the inner space of the fixed plate 1, and the first limiting portion 151 and the second limiting portion 152 respectively pass through the fixed plate 1 and are slidably connected to the sliding track so that they can slide closer to each other or slide away from each other, and the first limiting portion 151 and the second limiting portion 152 are connected by an elastic member provided in the inner space of the fixed plate 1 to clamp the solar cell panel 2 between the two parts of the first limiting portion 151 and the second limiting portion 152 exposed in the assembly area 11.

[0056] In some embodiments, see Figure 9 As shown, the surface of the fixing plate 1 provided with the assembly area 11 is also provided with a plurality of second retaining structures 16. Each second retaining structure 16 corresponds to the boundary of the assembly area 11, and each second retaining structure 16 has an insertion space 161 for inserting the solar panel 2. The insertion space 161 is provided with an electrical connection area to form the first electrical connection portion 12. In this way, the solar panel 2 can be inserted into the insertion space 161, and the second electrical connection portion 21 on the solar panel 2 contacts the first electrical connection portion 12 to achieve electrical connection. The second retaining structures 16 can be referred to as the first retaining structures 15, and will not be described in detail here.

[0057] In some embodiments, see Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figures 8 to 10As shown, a third electrical connection portion 17 is provided on the surface of the fixing plate 1 in the thickness direction, and a receiving space is provided inside the fixing plate 1. The receiving space is provided with a connecting wire connecting the third electrical connection portion 17 and the first electrical connection portion 12. In this way, the third electrical connection portion 17 can be connected to a power storage device or a power consumption device to provide power to the power storage device or the power consumption device. The connecting wire is located within the receiving space inside the fixing plate 1 to prevent the connecting wire from being cut or scratched.

[0058] Multiple first electrical connectors 12 can be connected in series or in parallel to the third electrical connector 17. When connected in parallel to the third electrical connector 17 and some solar panels 2 fail, the photovoltaic power generation device can still generate electricity, thereby improving the reliability and continuity of the photovoltaic power generation device's power supply. The third electrical connector 17 can be a connector with connecting pins (such as a USB connector), a cable, or other connection structure.

[0059] In some embodiments, see Figure 10 As shown, there are multiple fixing plates 1, and the multiple fixing plates 1 are movably connected. After being moved together, the multiple fixing plates 1 can be stacked along a predetermined direction. In this way, the area of ​​a single fixing plate 1 can be reduced, thereby reducing the storage space and transportation space requirements of the fixing plates 1.

[0060] In one example, a hinge (not shown) includes a first rotating piece and a second rotating piece rotatably connected by a rotating shaft. The first rotating piece is connected to the side of a fixed plate 1 facing away from the solar panel 2 thereon, and the second rotating piece is connected to the side of another fixed plate 1 facing away from the solar panel 2 thereon, so that the two fixed plates 1 can be rotated by the hinge to be stacked, and after stacking, the solar panels 2 on the two fixed plates 1 face away from each other. For example Figure 10 To rotate the opened image, Figure 11 The image is rotated and stacked.

[0061] In one example: the side of a fixed plate 1 facing away from the solar panel 2 thereon is slidably connected to the side of another fixed plate 1 corresponding to the solar panel 2 thereon, so that the two fixed plates 1 can be stacked after sliding relative to each other, and the two fixed plates 1 in the non-stacked state have a height difference, so as to adapt to environmental settings with height differences.

[0062] In some embodiments, the photovoltaic power generation device may further include a protective film (not shown) covering at least the side of the plurality of solar panels 2 facing away from the fixing plate 1 and the circumference of the fixing plate 1 in the thickness direction. If a solar panel 2 becomes damaged, the protective film corresponding to the location of the solar panel 2 can be cut away. After the damaged solar panel 2 is repaired or replaced, another protective film is applied to the cut location, completely covering the cutout. The protective film is then fixed to the original protective film by high-temperature melting, thereby forming a new protective structure with the remaining protective film.

[0063] The protective film can be made of a thin film material such as ethylene-vinyl acetate (EVA), which can be attached to the surface of the solar panel 2 facing away from the fixing plate 1 and to the surface of the fixing plate 1 in the thickness direction by melting at high temperature. The material of the protective film can be the same as or similar to that of the protective film. To further strengthen the connection between the protective film and the fixing plate 1, an adhesive such as glue can be used to bond the protective film and the surface of the fixing plate 1 in the thickness direction.
