[0037] In the prior art, the cover is installed with exposed nails, but the appearance is not good because the nails are exposed for a long time. As time goes by, the nailing is easy to loosen, the gap between the screw and the nail hole increases, and the risk of water leakage increases. In addition, the baseless buckle cover requires high installation and matching accuracy of the two plates to achieve tight buckling, because the buckle points are set on both sides of the plate, the installation tolerance is low and the installation efficiency is not high.

[0039] Embodiment 1

[0040] Reference Figure 1 and Figure 2 The present embodiment provides a building photovoltaic integrated assembly 100 including a first battery group 10, a second battery group 20, a connecting seat 30, a connecting piece 40 and a buckle cover 50. The first battery group 10 and the second battery group 20 are at least partially overlapped, the connecting seat 30 is at least partially arranged in an overlapping area between the first battery group 10 and the second battery group 20, the connecting piece 40 is passed through the connecting seat 30 and the overlapping area to fix the connecting seat 30 and the overlapping area, the buckle cover 50 is arranged on the connecting seat 30 and the overlapping area and shields the connecting piece 40, the connecting seat 30 forms a limiting protrusion 321, and the buckle cover 50 forms a buckle portion 521, the buckle portion 521 is snapped into the limiting protrusion 321 so that the buckle cover 50 and the connecting seat 30 are detachably connected together.

[0041] In the building photovoltaic integrated assembly 100 of the embodiment of the present application, the building photovoltaic integrated assembly 100 includes a first battery group 10, a second battery group 20, a connection seat 30, a connector 40 and a buckle cover 50. The first battery group 10 and the second battery group 20 are at least partially overlapped, the connection seat 30 is at least partially arranged in the overlap area between the first battery group 10 and the second battery group 20, the connector 40 is inserted in the connection seat 30 and the overlap area to fix the connection seat 30 and the overlap area, the buckle cover 50 is arranged in the connection seat 30 and the overlap area and shields the connector 40, the connection seat 30 forms a limited position convex portion 321, and the buckle cover 50 forms a buckle portion 521, and the buckle portion 521 is snapped into the limited position convex portion 321 so that the buckle cover 50 and the connection seat 30 are detachably connected together. In this way, the connection seat 30 is added between the first battery group 10 and the second battery group 20 and the fixed connection is achieved through the connector 40, so as to ensure the connection stability of the first battery group 10 and the second battery group 20. At the same time, the buckle cover 50 is arranged on the connection seat 30 to shield and protect the connection piece 40, so as to avoid the problem of water leakage in the connection hole, thereby increasing the installation tolerance of the building photovoltaic integrated assembly 100 and improving the installation efficiency. In addition, the buckle cover 50 is detachably connected to the connection seat 30, so that when dealing with water leakage or needing to replace related parts, the buckle cover 50 can be removed and reused.

[0042] Specifically, the specifications of the first battery pack 10 and the second battery pack 20 may be the same or different; the structures of the first battery pack 10 and the second battery pack 20 may be the same or different. The specific relationship between the first battery pack 10 and the second battery pack 20 is not limited here. In the embodiment of the present application, the first battery pack 10 and the second battery pack 20 are both solar cells.

[0043] Furthermore, the overlapping area can be the frame position of the first battery pack 10 and the second battery pack 20, and the frame is fixedly connected together through the connecting seat 30 and the connecting member 40 to ensure that the relative position of the first battery pack 10 and the second battery pack 20 is accurate and the connection is stable, while avoiding affecting the battery cells in the battery pack. The buckle cover 50 is arranged on the connecting seat 40 to protect the connecting seat 40 to avoid the connection member 30 and the connection hole through which the connecting member 30 passes being exposed to the outside, resulting in problems such as water leakage. In addition, the buckle cover 50 and the connecting seat 30 are detachably connected together by snapping the buckle portion 521 into the limiting protrusion 321. In this way, when the buckle cover 50 needs to be removed due to component damage or drainage, the buckle cover 50 can be directly removed from the connecting seat 30 and the buckle cover 50 can be reused.

[0044] It is understood that the "first" and "second" in the first battery pack 10 and the second battery pack 20 are relative concepts, referring to two different batteries.

It can be understood that in other embodiments, the battery on the left can also be marked as the second battery group 20, and the battery on the right can be marked as the first battery group 10.

[0045] Embodiment 2

[0046] Reference Figure 2 and Figure 3 In some optional embodiments, an accommodating space 60 is formed between the buckle cover 50 and the connecting seat 30 , and the accommodating space 60 is used to accommodate the connecting member 40 .

[0047] Specifically, the connection base 30 can at least partially fit the overlapping area of ​​the first battery pack 10 and the second battery pack 20, and the connection base 30 and the first battery pack 10 and the second battery pack 20 are firmly connected to each other through the connector 40. In order to make the buckle cover 50 avoid the influence of the connector 40 and increase the installation tolerance, the size of the buckle cover 50 is larger than the size of the connection base 30, so that after the buckle cover 50 covers the connection base 30, an accommodating space 60 can be formed between the buckle cover 50 and the connection base 30. In this way, when the connection base 30 and the first battery pack 10 and the second battery pack 20 are connected through the connector 40, the connector 40 can be at least partially arranged in the accommodating space 60. The protruding structure such as the protrusion of the connector 40 will not affect the covering of the buckle cover 50, so that the connection stability between the buckle cover 50 and the connection base 30 is improved, the installation is faster, and the appearance is improved.

[0048] For example, the connector 40 may be a rivet, and the rivet cap may be disposed inside the accommodation space 60, so that the rivet body may be inserted into the overlapped area and the connector 40 to ensure that the first battery pack 10 and the second battery pack 20 can be stably connected. Of course, in other embodiments, the connector 40 may also be a fixing member such as a screw to meet different requirements.

[0049] Embodiment 3

[0050] Reference Figure 2 and Figure 3 In some optional embodiments, the connecting seat 30 includes a receiving plate 31 and a first inclined plate 32, two first inclined plates 32 are connected to both sides of the receiving plate 31, and the limiting protrusion 321 is formed on the first inclined plate 32;

[0051] The buckle cover 50 includes a limiting plate 51 and a second inclined plate 52. The two second inclined plates 52 are connected to both sides of the limiting plate 51. The buckle portion 521 is formed on the second inclined plate 52.

[0052] When the buckle portion 521 is snapped into the limiting protrusion 321 , the receiving plate 31 and the limiting plate 51 are fitted together, and the first inclined plate 32 , the second inclined plate 52 and the limiting protrusion 321 define the accommodating space 60 .

[0053] Specifically, the cross-sections of the connecting seat 30 and the buckle cover 50 are both similar to a trapezoid, which has no lower bottom of the long side, but only a waist and an upper bottom of the short side. The cross-sections of the connecting seat 30 and the buckle cover 50 are two trapezoids without a long lower bottom. The buckle cover 50 is slightly larger than the size of the connecting seat 30, so that the buckle cover 50 can be easily covered on the connecting seat 30. In this way, the receiving plate 31 of the connecting seat 30 and the limiting plate 51 of the buckle cover 50 are equivalent to the upper bottoms of the short sides of the two trapezoids, and the first inclined plate 32 of the connecting seat 30 and the second inclined plate 52 of the buckle cover 50 are equivalent to the waists of two different trapezoids. At the same time, the limiting plate 51 should be longer than the receiving plate 31, and the first inclined plate 32 and the second inclined plate 52 corresponding to each other are inclined at a certain angle, and the inclination angle is the same. That is to say, after installation, the first inclined plate 32 on the left side of the receiving plate 31 and the second inclined plate 52 on the left side of the limiting plate 51 have the same inclination angle, and similarly, the first inclined plate 32 and the second inclined plate 52 on the right side have the same inclination angle. Of course, the inclination angles of the inclined plates on the left and right sides can be set to a suitable difference according to actual conditions. This makes it easier to install the buckle cover 50. When the buckle cover 50 is covered on the connecting seat 30, the limiting plate 51 will fit on the receiving plate 31, and a storage space 60 will be left between the first inclined plate 32 and the second inclined plate 52.

[0054] Further, in the two trapezoids, there is a limiting convex portion 321 on the waist of the trapezoid of the connection seat 30, and there is a buckle portion 521 on the waist of the trapezoid of the buckle cover 50, that is, the two limiting convex portions 321 are respectively formed on the ends of the two first inclined plates 32, and the two buckle portions 521 are respectively formed on the two second inclined plates 52. The limiting convex portion 321 is arranged in a triangular shape, and the triangle of the limiting convex portion 321 protrudes toward the buckle cover 50, and the buckle portion 521 is also arranged in a triangular shape, and the triangle of the buckle portion 521 protrudes toward the connection seat 30. In this way, when installing the buckle cover 50, the buckle cover 50 is placed on the connection seat 30 and pressed downward, and the buckle portion 521 of the buckle cover 50 can be accurately buckled with the limiting protrusion 321 on the connection seat 30, so that the buckle cover 50 is covered on the connection seat 30 and tightly clamped therewith, and at the same time, the limiting plate 51 is attached to the receiving plate 31, and the two protrusions support the accommodating space 60 between the first inclined plate 32 and the second inclined plate 52. However, when the buckle cover 50 is lifted in the reverse direction, due to the cooperation of the buckle portion 521 and the limiting protrusion 321, the buckle cover 50 will not fall off easily, ensuring the stability of the connection of the buckle cover 50. In this way, the installation tolerance and installation efficiency of the building photovoltaic integrated assembly 100 will be greatly improved, and the aesthetics can also be improved.

[0055] Furthermore, the receiving plate 31 is attached to the limiting plate 51, and the first inclined plate 32, the second inclined plate 52 and the limiting protrusion 321 define the accommodating space 60. In this way, the receiving plate 31 can receive the limiting plate 51, so that the pressure of the entire buckle cover 50 can be evenly distributed; and the connecting member 40 is arranged in the accommodating space 60, which avoids the connecting member 40 from bearing pressure, protects the connecting member 40, and makes the connecting member 40 not occupy additional space. At the same time, after the connecting member 40 is inserted, the overall thickness of the assembly is not increased in the thickness direction, thereby improving the space utilization rate and enhancing the aesthetics.

[0056] Embodiment 4

[0057] Reference Figure 4 and Figure 5 In some optional embodiments, the first battery pack 10 includes a first main body portion 11 and a first bending portion 12, the first bending portion 12 is arranged at an edge of the first main body portion 11 close to the second battery pack 20, the second battery pack 20 includes a second main body portion 21 and a second bending portion 22, the second bending portion 22 is arranged at an edge of the second main body portion 21 close to the first battery pack 10, the first bending portion 12 is at least partially embedded in the second bending portion 22 to form an overlapping area, and the connecting seat 30 is covered on a side of the second bending portion 22 away from the first bending portion 12.

[0058] Specifically, in the building photovoltaic integrated assembly 100, multiple battery packs need to be connected to achieve actual needs. Now, the connection between two battery packs is used as an analogy for the connection of multiple battery packs.

[0059] Furthermore, in order to make the first battery pack 10 and the second battery pack 20 tightly and firmly connected together, it is necessary to set structures that can be connected to each other at the edges of different battery packs, and through this connection structure, different battery packs can be positioned and connected together. In other words, the connection between the first battery pack 10 and the second battery pack 20 is achieved through the first bending portion 12 and the second bending portion 22. In this way, the first main body portion 11 and the second main body portion 21 as the main parts of the battery pack for photoelectric effect can also be indirectly connected together. The first bending portion 12 can be set to be an M-shaped bend, and the second bending portion 22 is also bent accordingly, so that the first bending portion 12 and the second bending portion 22 can fit each other, thereby increasing the connection stability between the first bending portion 12 and the second bending portion 22.

[0060] Furthermore, in the actual installation process, the first bending portion 12 and the second bending portion 22 can be connected together accordingly, and then the connecting seat 30 is covered on the second bending portion 22. The connecting seat 30 is connected to the second bending portion 22, and the connecting seat 30 is a trapezoidal setting. The trapezoidal connecting seat 30 is covered on the M-shaped setting of the second bending portion 22, so that the connecting seat 30 and the second bending portion 22 are matched and connected. In this way, the first bending portion 12, the second bending portion 22 and the connecting seat 30 can be connected together. Of course, the first bending portion 12 and the second bending portion 22 can be nested together and fixedly connected together by the connecting member 40, and then the connecting seat 30 can be nested on the second bending portion 22, and the connecting seat 30 and the overlapping area can be fixedly connected together by another connecting member 40, so that the three parts are firmly connected together.

[0061] Embodiment 5

[0062] Reference Figure 4 and Figure 5 In some optional embodiments, the first bending portion 12 includes a first convex portion 121, a first connecting plate 122 and a second convex portion 123 connected together in sequence;

[0063] The second bending portion 22 includes a third convex portion 221, a second connecting plate 222 and a fourth convex portion 223 which are connected in sequence;

[0064] The first convex portion 121 and the fourth convex portion 223 are correspondingly fitted, the first connecting plate 122 and the second connecting plate 222 are correspondingly fitted, and the second convex portion 123 and the third convex portion 221 are correspondingly fitted.

[0065] In this embodiment, on the cross-section of the building photovoltaic integrated component 100, the first body portion 11 and the second body portion 21 can extend along the first direction, the first convex portion 121 and the second convex portion 123 can protrude along the second direction, and similarly, the third convex portion 221 and the fourth convex portion 223 can also protrude along the second direction, wherein the first direction and the second direction are perpendicular directions. The fourth convex portion 223 of the second bending portion 22 is set to a convex shape matching the first convex portion 121, so that the first convex portion 121 and the fourth convex portion 223 can be well fitted. Similarly, the second convex portion 123 of the first bending portion 12 is set to be convex in the direction of the second bending portion 22, and the third convex portion 221 of the second bending portion 22 is set to be a convex shape matching the second convex portion 123, so that the second convex portion 123 and the third convex portion 221 can be well fitted. The cross-sectional shape of the convex portion can be set to be trapezoidal, and of course, other various shapes can be set according to actual needs, such as semicircle, square, triangle, and there is no limitation here.

[0066] Furthermore, the first protrusion 121 and the second protrusion 123 of the first bending portion 12 are connected by a first connecting plate 122, so that the first protrusion 121 and the second protrusion 123 are connected as an integral structure, and the third protrusion 221 and the fourth protrusion 223 of the second bending portion 22 are connected by a second connecting plate 222, so that the third protrusion 221 and the fourth protrusion 223 are connected as an integral structure. In this way, when the first protrusion 121 fits with the fourth protrusion 223, and the second protrusion 123 fits with the third protrusion 221, the first bending portion 12 and the second bending portion 22 will fit together in an M-shape as a whole, so that the first bending portion 12 and the second bending portion 22 fit more tightly and firmly, making the connection between battery packs simpler and faster, and increasing the installation tolerance.

[0067] Embodiment 6

[0068] Refer to the figure Figure 1 and Figure 2 In some optional embodiments, the first connecting plate 122 and the first body portion 11 are arranged on the same horizontal plane;

[0069] In the thickness direction of the building photovoltaic integrated assembly 100, the second body portion 21 is arranged at a position closer to the connection seat 30 relative to the first body portion 11;

[0070] In the thickness direction of the building photovoltaic integrated assembly 100 , the second connecting plate 222 is arranged at a position closer to the connecting seat 30 relative to the second body portion 21 .

[0071] Specifically, in the building photovoltaic integrated component 100, the first battery group 10 and the second battery group 20 are generally connected on the same plane. When the first battery group 10 and the second battery group 20 are connected on the same plane, the first bending portion 12 is subjected to the pressure of the second bending portion 22, and the pressure of the first connecting plate 122 of the corresponding first bending portion 12 increases. In order to reduce the deformation of the first connecting plate 122 due to the force, the first connecting plate 122 of the first bending portion 12 is arranged on the same horizontal plane as the first main body 11, so that the pressure of the first connecting plate 122 is offset by the plane where the first battery group 10 is located, reducing the stress between the first connecting plate 122 and the first main body 11 in the vertical direction, and ensuring the overall connection stability. In this embodiment, the second direction is the thickness direction of the building photovoltaic integrated component 100.

[0072] Furthermore, when the second bent portion 22 of the second battery pack 20 is engaged with the first bent portion 12 of the first battery pack 10 on a side close to the connection seat 30, the second bent portion 22 will be closer to the connection seat 30 than the first bent portion 12, and the second body portion 21 of the second battery pack 20 together with the second bent portion 22 will also be closer to the connection seat 30 relative to the first body portion 11 in the thickness direction. In this way, the first battery pack 10 and the second battery pack 20 can be positioned to ensure that the battery pack composed of the first battery pack 10 and the second battery pack 20 is not too thick in the thickness direction.

[0073] Furthermore, due to the deformation caused by gravity and other factors, the positions of the second body portion 21 and the second bending portion 22 of the second battery pack 20 in the thickness direction will change. That is to say, in the thickness direction, the second connecting plate 222 is supported by the first connecting plate 122, so the second connecting plate 222 is closer to the connecting seat 30 relative to the second body portion 21.

[0074] In the embodiment of the present application, there is no limitation on the positions of the first battery pack 10 and the second battery pack 20 and their components in the thickness direction, so as to meet various requirements.
