Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic panel connection structure, a photovoltaic module, a photovoltaic curtain wall and a photovoltaic power generation device. Background Art

[0002] Solar photovoltaic curtain wall is a new form of photovoltaic building integration application. It can directly convert sunlight energy into electrical energy based on the principle of solar power generation. It can be a photovoltaic awning, photovoltaic skylight or building wall structure.

[0003] A photovoltaic curtain wall usually includes multiple photovoltaic panels, which are connected by a connecting structure. However, the existing connecting structure is easily torn and damaged by external forces, resulting in loss of waterproof and air-proof functions, causing the photovoltaic curtain wall to leak water and air. Utility Model Content

[0004] In view of the problem, the present application provides a photovoltaic panel connection structure, a photovoltaic module, a photovoltaic curtain wall and a photovoltaic power generation device, which can alleviate the problem that the photovoltaic panel connection structure of the photovoltaic curtain wall is easily torn and damaged by external force, resulting in loss of waterproof and air-proof functions, causing water and air leakage in the photovoltaic curtain wall.

[0005] In a first aspect, the present application provides a photovoltaic panel connection structure, comprising:

[0006] A first frame, comprising a first connecting portion and a male docking portion arranged opposite to each other along a first direction, wherein the first connecting portion is used to be connected to the photovoltaic panel;

[0007] A second frame, comprising a second connecting portion and a female docking portion arranged opposite to each other along a first direction, wherein the second connecting portion is used to be connected to another photovoltaic panel;

[0008] Among them, the male docking part and the female docking part are plugged into each other, and both have contact surfaces facing each other when plugged in, and the contact surface of at least one of the male docking part and the female docking part is provided with a contact convex portion; the contact surface of one of the male docking part and the female docking part contacts with the contact convex portion of the other of the male docking part and the female docking part along the second direction; the first direction intersects with the second direction.

[0009] In this way, by plugging the male docking part and the female docking part into each other, the connection structure between the first frame and the second frame can be simplified, and the two can be quickly matched. Secondly, when the photovoltaic panel connected to the first frame and the photovoltaic panel connected to the second frame are subjected to different wind loads, the contact surface of one of the male docking part and the female docking part contacts the contact protrusion of the other of the male docking part and the female docking part along the second direction, and the second direction is consistent with the direction of the wind load. Therefore, the load can be transferred through the contact between the contact surface and the contact protrusion, so that the first frame and the second frame can be deformed cooperatively, thereby reducing the enlargement of the gap between the first frame and the second frame and reducing the risk of failure of the waterproof and airproof functions.

[0010] In addition, since the male docking part and the female docking part are in contact with each other through the contact surface and the contact convex part, the contact area is reduced. When subjected to different wind loads, the abnormal noise caused by movement friction between the male docking part and the female docking part can also be reduced.

[0011] In some embodiments, the male docking portion and the female docking portion are plugged into each other along a first direction.

[0012] By arranging the male docking part and the female docking part to be plugged in along a first direction, the plug of the male docking part and the socket of the female docking part can constrain each other along a second direction intersecting the first direction. Further, when the photovoltaic panel connected to the first frame and the photovoltaic panel connected to the second frame are subjected to different wind loads, the two frames distribute the load according to the size of the cross-sectional moment of inertia, thereby cooperatively deforming, making it difficult for the male docking part and the female docking part to separate from each other in the second direction, thereby improving the structural reliability of the photovoltaic panel connection structure.

[0013] In some embodiments, the male docking portion includes a plug, the female docking portion includes a socket, and the plug is plugged into the socket;

[0014] The male docking portion includes a first convex rib and a second convex rib both extending in a first direction away from the first connecting portion, the first convex rib and the second convex rib are opposite to each other and spaced apart in the second direction to form a plug, and the first convex rib and the second convex rib have a contact surface on one side facing away from each other; and / or

[0015] The female docking portion includes a third rib and a fourth rib extending away from the second connection portion along the first direction. The third rib and the fourth rib are opposite to each other and spaced apart along the second direction to form a socket. The third rib and the fourth rib have contact surfaces on one side facing each other.

[0016] The first convex rib and the second convex rib are arranged opposite to each other and spaced apart along the second direction to form a plug, which simplifies the manufacturing process of the first frame. The third convex rib and the fourth convex rib are arranged opposite to each other and spaced apart along the second direction to form a plug, which simplifies the manufacturing process of the second frame.

[0017] In some embodiments, the contact surfaces of the male docking portion and the female docking portion are both provided with contact convex portions, the contact convex portions of the male docking portion are in contact with the contact surface of the female docking portion along the second direction, and the contact convex portions of the female docking portion are in contact with the contact surface of the male docking portion along the second direction;

[0018] The contact protrusions of the male docking portion and the female docking portion are arranged opposite to each other along a first direction.

[0019] Since the male docking part and the female docking part are plugged in along the first direction, by arranging the contact protrusions of the male docking part and the female docking part to be relatively arranged along the first direction, the contact protrusions of the two can form a limit constraint on each other in the plugging direction of the male docking part and the female docking part, and the male docking part and the female docking part cannot be easily disengaged in the plugging direction, thereby further improving the structural reliability of the photovoltaic panel connection structure.

[0020] In some embodiments, the male docking part and the female docking part have at least one group of contact surfaces facing each other, each of the contact surfaces facing each other is provided with a contact protrusion, the contact protrusions of the male docking part corresponding to the contact surfaces facing each other are in contact with the contact surface of the female docking part along the second direction, the contact protrusions of the female docking part corresponding to the contact surfaces facing each other are in contact with the contact surface of the male docking part along the second direction, and the contact protrusions of the male docking part and the female docking part corresponding to the contact surfaces facing each other are arranged relative to each other along the first direction, and the contact protrusions of the male docking part corresponding to the contact surfaces facing each other are closer to the second connecting part than the contact protrusions of the female docking part.

[0021] By arranging the contact protrusions of the male docking part and the female docking part corresponding to each group of contact surfaces relatively to each other along the first direction, the contact protrusions of the male docking part corresponding to the contact surfaces facing each other are closer to the second connecting part than the contact protrusions of the female docking part, and the position setting of the contact protrusions of the male docking part compared with the contact protrusions of the female docking part can be more reliably defined. Furthermore, the male docking part and the female docking part cannot be easily disengaged in the plug-in direction.

[0022] In some embodiments, the contact protrusion includes an elastic contact protrusion that elastically contacts the contact surface.

[0023] By providing the contact protrusion including an elastic contact protrusion to elastically contact with the contact surface, on the one hand, since the contact between the contact protrusion and the contact surface becomes elastic contact and is non-rigid contact, when the photovoltaic panels on both sides are subjected to different wind loads, the abnormal noise generated by movement friction between the male docking part and the female docking part can be further reduced. On the other hand, the stress concentration caused by the contact between the elastic contact protrusion and the contact surface can also be reduced, thereby improving the service life of the first frame and the second frame.

[0024] In some embodiments, the photovoltaic panel connection structure further includes a sealant filled between the first frame and the second frame.

[0025] The method of sealing the first frame and the second frame by filling sealant between the first frame and the second frame is simple and the sealing is reliable.

[0026] In some embodiments, the first connecting portion includes a first opening groove opening along a first direction toward the back of the male docking portion, and the first opening groove is used to accommodate a portion of the photovoltaic panel to be connected to the photovoltaic panel; and / or

[0027] The second connecting portion includes a second opening groove that opens along the first direction toward the back of the female docking portion, and the second opening groove is used to accommodate a portion of another photovoltaic panel to be connected to the other photovoltaic panel.

[0028] By setting the first opening groove for accommodating a portion of the photovoltaic panel so as to be connected to the photovoltaic panel, the contact area between the first opening groove and the photovoltaic panel is also larger, and the first opening groove can limit the non-opening side of the photovoltaic panel, thereby improving the connection reliability. By setting the second opening groove for accommodating a portion of the photovoltaic panel so as to be connected to the photovoltaic panel, the contact area between the second opening groove and the photovoltaic panel is also larger, and the second opening groove can limit the non-opening side of the photovoltaic panel, thereby improving the connection reliability.

[0029] In a second aspect, a photovoltaic assembly is also provided, comprising a plurality of photovoltaic panels and the photovoltaic panel connection structure in any of the above embodiments.

[0030] In a third aspect, a photovoltaic curtain wall is also provided, comprising a supporting body and the photovoltaic assembly in any of the above embodiments, wherein the photovoltaic panel connection structure is connected to the supporting body.

[0031] In some embodiments, the photovoltaic curtain wall further includes at least one elastic buckle, and the first frame and / or the second frame is connected to the main body via the at least one elastic buckle.

[0032] In the related art, bolts and the like are often used to connect the frames, but the operating space in the frame is small, resulting in low installation efficiency. However, the present application sets the first frame to be connected to the main body through an elastic buckle, so that the installation between the first frame and the main body is not limited by the operating space of the first frame, and the first frame and the main body can be installed efficiently, reducing the construction period. Similarly, the second frame can also be connected to the main body through an elastic buckle, so that the second frame and the main body can be installed efficiently, reducing the construction period.

[0033] In some embodiments, the first frame further includes a first extension portion arranged opposite to the first connection portion along the second direction, the first extension portion extends along the first direction toward a side away from the male docking portion, and the first extension portion is connected to the main body via at least one elastic buckle; and / or

[0034] The second frame also includes a second extension portion arranged opposite to the second connection portion along the second direction, the second extension portion extends along the first direction toward a side away from the female docking portion, and the second extension portion is connected to the main body via at least one elastic buckle.

[0035] Since the first extension part is located on the same side as the first connection part and is arranged opposite to the first connection part along the second direction, when connecting with the main body, it does not affect the connection between the male docking part and the female docking part, nor does it affect the connection between the first connection part and the photovoltaic panel, and there is enough space to connect with the main body through the elastic buckle, which simplifies the connection operation. Since the second extension part is located on the same side as the second connection part and is arranged opposite to the second connection part along the second direction, when connecting with the main body, it does not affect the connection between the female docking part and the male docking part, nor does it affect the connection between the second connection part and the photovoltaic panel, and there is enough space to connect with the main body through the elastic buckle, which simplifies the connection operation.

[0036] In some embodiments, the body includes at least one C-shaped purlin, each C-shaped purlin includes a web and a flange connected to one side of the web;

[0037] In the second direction, the flange plate of one of the C-shaped purlins is in contact with the side of the first extension portion facing away from the first connecting portion, and is connected to the first extension portion by at least one elastic buckle; and / or

[0038] In the second direction, the flange plate of another C-shaped purlin is in contact with a side of the second extension portion facing away from the second connecting portion, and is connected to the second extension portion via at least another elastic buckle.

[0039] Since the flange plate of the C-shaped purlin is in contact with the side of the first extension portion facing away from the first connecting portion, the first frame can be reliably supported by the first extension portion, and the flange plate of the C-shaped purlin has a relatively simple structure, the connection operation is further simplified by connecting it with the first extension portion through at least one elastic clip. Since the flange plate of the C-shaped purlin is in contact with the side of the second extension portion facing away from the second connecting portion, the second frame can be reliably supported by the second extension portion, and the flange plate of the C-shaped purlin has a relatively simple structure, the connection operation is further simplified by connecting it with the second extension portion through at least one elastic clip.

[0040] In some embodiments, the flange plate of each C-shaped purlin includes a plate body and a bent portion, one end of the plate body is connected to the web, the other end of the plate body is connected to the bent portion, and an angle is formed between the plate body and the bent portion; each elastic clip includes a first elastic snap-fitting groove and a second elastic snap-fitting groove that are connected;

[0041] The plate body of one C-shaped purlin is fitted with the first extension portion, and at least part of the plate body and at least part of the first extension portion are clamped in the first elastic clamping groove, and the bent portion is clamped in the second elastic clamping groove; and / or

[0042] The plate body of another C-shaped purlin is fitted with the second extension portion, and at least part of the plate body and at least part of the second extension portion are clamped in the first elastic clamping groove, and the bent portion is clamped in the second elastic clamping groove.

[0043] Since the plate body of the C-shaped purlin fits with the first extension portion, the plate body and the first extension portion both extend along the first direction. When they are clamped in the first elastic clamping groove together, the first extension portion can be limited in the second direction, so that the first frame is not easy to move relative to the main body in the second direction. At the same time, an angle is formed between the plate body and the bending portion. When the bending portion is clamped in the second elastic clamping groove, the bending portion can limit the elastic buckle in the direction intersecting with the second direction (including the first direction), and then under the action of the elastic buckle, the first frame is not easy to move relative to the main body in the direction intersecting with the second direction. Similarly, since the plate body of the C-shaped purlin fits with the second extension part, the plate body and the second extension part both extend along the first direction. When they are clamped together in the first elastic clamping groove, the second extension part can be limited in the second direction, so that the second frame is not easy to move relative to the main body in the second direction. At the same time, an angle is formed between the plate body and the bending part. When the bending part is clamped in the second elastic clamping groove, the bending part can limit the elastic buckle in the direction intersecting with the second direction (including the first direction), and then under the action of the elastic buckle, the second frame is not easy to move relative to the main body in the direction intersecting with the second direction. Therefore, by setting the first elastic clamping groove and the second elastic clamping groove, the movement of the first frame and the photovoltaic panel connected thereto under different forces can be effectively fixed, thereby improving the reliability of the photovoltaic curtain wall.

[0062] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It mainly includes structures such as photovoltaic panels, controllers and inverters. Among them, solar photovoltaic curtain walls are a new form of photovoltaic building integration application. In practical applications, they can be photovoltaic awnings, photovoltaic skylights or building wall structures. Photovoltaic awnings are usually set up outdoors. They can be used as regular awnings, as carports to shelter vehicles from wind and rain, and as photovoltaic power stations to generate electricity. They can be used with charging piles to charge electric vehicles, and at the same time, excess electricity can be fed back to the power grid. Photovoltaic skylights are usually set up indoors, such as in the patio of a shopping mall. They can not only collect light, but also generate electricity for the mall.

[0063] In the related art, the photovoltaic curtain wall includes multiple photovoltaic panels, and the multiple photovoltaic panels are connected together through a connection structure. These connection structures usually include a frame, which is arranged around the periphery of the photovoltaic panel to form a photovoltaic module, and the multiple photovoltaic modules are connected to each other through the frame, and then a sealant is filled between the frames of two adjacent photovoltaic modules to achieve a waterproof and windproof effect.

[0064] However, when the wind pressure, snow pressure and other loads between two adjacent photovoltaic modules are of different sizes, the deformation between the two adjacent frames will be inconsistent, the gap between the frames will become larger, and the sealant will be easily torn and damaged, resulting in the loss of waterproof and air-proof functions, causing the photovoltaic curtain wall to leak water and air.

[0065] In order to alleviate the problem that the gap between the frames becomes larger due to external forces, which makes the sealant easily torn and damaged, resulting in the loss of waterproof and airproof functions, and causing the photovoltaic curtain wall to leak and air, the embodiment of the present application designs a photovoltaic panel connection structure, including a first frame and a second frame, the first frame includes a first connection part and a male docking part relatively arranged along a first direction, and the first connection part is used to connect with the photovoltaic panel; the second frame includes a second connection part and a female docking part relatively arranged along the first direction, and the second connection part is used to connect with another photovoltaic panel. Among them, the male docking part and the female docking part are plugged into each other, and both have contact surfaces facing each other when plugged in, and the contact surface of at least one of the male docking part and the female docking part is provided with a contact convex part. The contact surface of one of the male docking part and the female docking part contacts the contact convex part of the other of the male docking part and the female docking part along the second direction, and the first direction intersects with the second direction.

[0066] In this way, by plugging the male docking part and the female docking part into each other, the connection structure between the first frame and the second frame can be simplified, and the two can be quickly matched. Secondly, when the photovoltaic panel connected to the first frame and the photovoltaic panel connected to the second frame are subjected to different wind loads, the contact surface of one of the male docking part and the female docking part contacts the contact protrusion of the other of the male docking part and the female docking part along the second direction, and the second direction is consistent with the direction of the wind load. Therefore, the load can be transferred through the contact between the contact surface and the contact protrusion, so that the first frame and the second frame can be deformed cooperatively, thereby reducing the enlargement of the gap between the first frame and the second frame and reducing the risk of failure of the waterproof and airproof functions.

[0067] In addition, since the male docking part and the female docking part are in contact with each other through the contact surface and the contact convex part, the contact area is reduced. When subjected to different wind loads, the abnormal noise caused by movement friction between the male docking part and the female docking part can also be reduced.

[0068] The photovoltaic panel connection structure of the present application can be applied to photovoltaic curtain walls, specifically photovoltaic awnings and photovoltaic skylights, to alleviate the misalignment between frames due to external forces, which makes it easy for the sealant to be torn and damaged, resulting in the loss of waterproof and air-proof functions, and causing the risk of water leakage and air leakage.

[0069] Figure 1 is a partial structural schematic diagram of a photovoltaic panel connection structure according to one or more embodiments, Figure 2 for Figure 1 The enlarged schematic diagram of the photovoltaic panel connection structure at part A is shown in the attached figure. Figure 1 and 2 The embodiment of the present application provides a photovoltaic panel connection structure 100, including a first frame 10 and a second frame 20. The first frame 10 includes a first connection portion 11 and a male docking portion 12 arranged opposite to each other along a first direction, and the first connection portion 11 is used to connect to the photovoltaic panel 200. The second frame 20 includes a second connection portion 21 and a female docking portion 22 arranged opposite to each other along the first direction, and the second connection portion 21 is used to connect to another photovoltaic panel 200. Among them, the male docking portion 12 and the female docking portion 22 are plugged into each other, and both have contact surfaces 30 facing each other when plugged in, and the contact surface 30 of at least one of the male docking portion 12 and the female docking portion 22 is provided with a contact convex portion 31. The contact surface 30 of one of the male docking portion 12 and the female docking portion 22 contacts the contact convex portion 31 of the other of the male docking portion 12 and the female docking portion 22 along the second direction, and the first direction intersects the second direction.

[0070] The first frame 10 and the second frame 20 are frames for supporting the photovoltaic panel 200, and can specifically abut against the lower surface and the side of the photovoltaic panel 200. In order to achieve a better supporting effect, the frame generally selects a metal material with a certain thickness and hardness that meets the supporting requirements of the photovoltaic panel 200, such as aluminum alloy.

[0071] Specifically, the first frame 10 is connected to the photovoltaic panel 200 through the first connecting part 11, and the second frame 20 is connected to the photovoltaic panel 200 through the second connecting part 21. The connection method between the first connecting part 11 and the second connecting part 21 and the photovoltaic panel 200 can be fixed or detachably connected.

[0072] The male docking part 12 and the female docking part 22 are plugged into each other, which means that the male docking part 12 has a plug feature and the female docking part 22 has a socket feature, so that when the two are connected, the plug can be inserted into the socket for matching. The plug may include a protrusion structure formed on the male docking part 12, and the socket may include a groove structure formed on the female docking part. The specific formation method of the plug and the socket is not limited in the embodiments of the present application. In addition, the number of male docking parts 12 with plug features and the number of female docking parts 22 with socket features can be single or multiple.

[0073] The contact surface 30 refers to a surface that can contact other parts. The contact convex portion 31 refers to a protrusion that protrudes from the contact surface 30 to contact other parts. The contact convex portion 31 can be a structure formed by a part of the surface of the contact surface 30 protruding outward, or it can be a protrusion structure formed by an additional part provided on the contact surface 30.

[0074] In the embodiment of the present application, both the male docking portion 12 and the female docking portion 22 have a contact convex portion 31, the contact surface 30 of the male docking portion 12 contacts the contact convex portion 31 of the female docking portion 22 along the second direction, and the contact surface 30 of the female docking portion 22 contacts the contact convex portion 31 of the male docking portion 12 along the second direction. Of course, in other embodiments, only one of the male docking portion 12 and the female docking portion 22 may have a contact surface, while the other may have a contact convex portion.

[0075] The first direction can be specifically Figure 1 The X direction shown, the second direction can be specifically Figure 1 Of course, the second direction may also be other directions intersecting with the first direction.

[0076] In this way, by plugging the male docking part 12 and the female docking part 22 into each other, the connection structure between the first frame 10 and the second frame 20 can be simplified, and the two can be quickly matched. Secondly, when the photovoltaic panel 200 connected to the first frame 10 and the photovoltaic panel 200 connected to the second frame 20 are subjected to different wind load sizes, since the contact surface 30 of one of the male docking part 12 and the female docking part 22 is in contact with the contact protrusion 31 of the other of the male docking part 12 and the female docking part 22 along the second direction, and the second direction is consistent with the direction of the wind load, the load can be transferred through the contact between the contact surface 30 and the contact protrusion 31, thereby enabling the first frame 10 and the second frame 20 to deform cooperatively, thereby reducing the situation where the gap between the first frame 10 and the second frame 20 becomes larger, and reducing the risk of failure of the waterproof and airproof functions.

[0077] In addition, since the male docking part 12 and the female docking part 22 are in contact with each other through the contact surface 30 and the contact protrusion 31, the contact area is reduced. When subjected to different wind loads, the abnormal noise caused by movement friction between the male docking part 12 and the female docking part 22 can also be reduced.

[0078] Please continue reading Figure 2 According to some embodiments of the present application, the male docking portion 12 and the female docking portion 22 are plugged together along the first direction X.

[0079] The male docking part 12 and the female docking part 22 are plugged together along the first direction X, which means that the plug of the male docking part 12 is arranged opposite to the socket of the female docking part 22 along the first direction. In this way, when the two are plugged together, they can be plugged together along the first direction X.

[0080] Therefore, by setting the male docking part 12 and the female docking part 22 to be plugged in along the first direction X, the plug of the male docking part 12 and the socket of the female docking part 22 can form a constraint with each other along the second direction Z intersecting with the first direction X, and then when the photovoltaic panel 200 connected to the first frame 10 and the photovoltaic panel 200 connected to the second frame 20 are subjected to different wind loads, the two frames distribute the load according to the size of the cross-sectional moment of inertia, thereby cooperatively deforming, and it is not easy for the male docking part 12 and the female docking part 22 to separate from each other in the second direction Z, thereby improving the structural reliability of the photovoltaic panel connection structure 100.

[0081] Furthermore, the male docking portion 12 includes a plug, and the female docking portion 22 includes a socket, and the plug is plugged into the socket. The male docking portion 12 includes a first convex rib 121 and a second convex rib 122, both of which protrude away from the first connecting portion 11 along the first direction X, and the first convex rib 121 and the second convex rib 122 are opposite to each other and spaced apart along the second direction Z to form a plug, and the first convex rib 121 and the second convex rib 122 have a contact surface 30 on the side facing away from each other.

[0082] The convex rib refers to a protruding rib structure. In the embodiment of the present application, the cross-sectional shape of the convex rib is substantially a solid rectangle or other polygon; in other embodiments, the cross-sectional shape of the convex rib may also be a hollow rectangle or other polygon to reduce the weight of the frame.

[0083] The method of arranging the first convex rib 121 and the second convex rib 122 to be opposite and spaced apart along the second direction Z to form the plug is simpler, thereby simplifying the manufacturing process of the first frame 10 .

[0084] In other embodiments, the female docking portion 22 includes a third rib 221 and a fourth rib 222 both protruding along the first direction X away from the second connecting portion 21, the third rib 221 and the fourth rib 222 are opposite to each other and are spaced apart along the second direction Z to form a socket, and the third rib 221 and the fourth rib 222 have a contact surface 30 on one side facing each other.

[0085] Similarly, the method of arranging the third rib 221 and the fourth rib 222 to be opposite to each other and spaced apart along the second direction Z to form the plug is simpler, thereby simplifying the manufacturing process of the second frame 20 .

[0086] In other embodiments, the male docking portion 12 includes a first rib 121 and a second rib 122 both protruding along the first direction X away from the first connecting portion 11, the first rib 121 and the second rib 122 are opposite to each other and spaced apart along the second direction Z to form a plug, and the female docking portion 22 includes a third rib 221 and a fourth rib 222 both protruding along the first direction X away from the second connecting portion 21, the third rib 221 and the fourth rib 222 are opposite to each other and spaced apart along the second direction Z to form a socket.

[0087] Please continue reading Figure 2 According to some embodiments of the present application, the contact surfaces 30 of the male docking portion 12 and the female docking portion 22 are both provided with contact convex portions 31, and the contact convex portions 31 of the male docking portion 12 are in contact with the contact surface 30 of the female docking portion 22 along the second direction Z, and the contact convex portions 31 of the female docking portion 22 are in contact with the contact surface 30 of the male docking portion 12 along the second direction Z. The contact convex portions 31 of the male docking portion 12 and the female docking portion 22 are arranged opposite to each other along the first direction X.

[0088] Since the male docking part 12 and the female docking part 22 are plugged in along the first direction X, by arranging the contact protrusions 31 of the male docking part 12 and the female docking part 22 relatively along the first direction X, the contact protrusions 31 of the male docking part 12 and the female docking part 22 can form a limit constraint on each other in the plugging direction of the male docking part 12 and the female docking part 22, and the male docking part 12 and the female docking part 22 cannot be easily disengaged in the plugging direction, thereby further improving the structural reliability of the photovoltaic panel connection structure 100.

[0089] Specifically, the male docking part 12 and the female docking part 22 have at least one group of contact surfaces 30 facing each other, and each contact surface 30 facing each other has a contact protrusion 31. The contact protrusion 31 of the male docking part 12 corresponding to the contact surfaces 30 facing each other contacts with the contact surface 30 of the female docking part 22 along the second direction Z, and the contact protrusion 31 of the female docking part 22 corresponding to the contact surfaces 30 facing each other contacts with the contact surface 30 of the male docking part 12 along the second direction Z, and the contact protrusions 31 of the male docking part 12 and the female docking part 22 corresponding to the contact surfaces 30 facing each other are arranged relative to each other along the first direction, and the contact protrusion 31 of the male docking part 12 corresponding to the contact surfaces 30 facing each other is closer to the second connecting part 21 than the contact protrusion 31 of the female docking part 22.

[0090] In an embodiment of the present application, the male docking portion 12 and the female docking portion 22 have two sets of contact surfaces 30 facing each other, one set of contact surfaces 30 is provided at the first rib 121 and the third rib 221 , and the other set of contact surfaces 30 is provided at the second rib 122 and the fourth rib 222 .

[0091] By arranging the contact protrusions 31 of the male docking part 12 and the female docking part 22 corresponding to each group of contact surfaces 30 relatively to each other along the first direction, the male docking part 12 and the female docking part 22 can be more reliably defined. Furthermore, the contact protrusions 31 of the male docking part 12 corresponding to the contact surfaces 30 facing each other are closer to the second connecting part 21 than the contact protrusions 31 of the female docking part 22, so that the contact protrusions 31 of the male docking part 12 form a limiting constraint compared to the contact protrusions 31 of the female docking part 22, and the male docking part 12 and the female docking part 22 cannot be easily disengaged in the plug-in direction.

[0092] According to some embodiments of the present application, the contact protrusion 31 includes an elastic contact protrusion, and the elastic contact protrusion is in elastic contact with the contact surface 30 .

[0093] The elastic contact protrusion means that the contact protrusion has elasticity. When the elastic contact protrusion contacts the contact surface 30, it can be squeezed to generate elastic deformation and be compressed.

[0094] By providing the contact protrusion 31 including an elastic contact protrusion to elastically contact with the contact surface 30, on the one hand, since the contact between the contact protrusion 31 and the contact surface 30 becomes elastic contact, which is a non-rigid contact, when the photovoltaic panels 200 on both sides are subjected to different wind loads, the abnormal noise generated by the movement friction between the male docking part 12 and the female docking part 22 can be further reduced. On the other hand, the stress concentration caused by the contact between the elastic contact protrusion and the contact surface 30 can also be reduced, thereby improving the service life of the first frame 10 and the second frame 20.

[0095] Optionally, the elastic contact protrusion may be made of rubber, silicone, etc. The material of the elastic contact protrusion may be different from the material of the remaining structures of the first frame 10 and the second frame 20. For example, the material of the remaining structures of the first frame 10 and the second frame 20 is a metal material, and the elastic contact protrusion may be fixed by bonding or clamping it to the remaining structures of the first frame 10 and the second frame 20.

[0096] Please continue reading Figure 2 According to some embodiments of the present application, the first connecting portion 11 includes a first opening groove 111 opening along the first direction X away from the male docking portion 12 , and the first opening groove 111 is used to accommodate a portion of the photovoltaic panel 200 to be connected to the photovoltaic panel 200 .

[0097] Specifically, the opening of the first connecting portion 11 is arranged along the first direction X away from the male docking portion 12 , that is, the side away from the male docking portion 12 forms an opening, and the side close to the male docking portion 12 forms the bottom wall of the groove.

[0098] By providing the first opening groove 111 to accommodate part of the photovoltaic panel 200 so as to be connected to the photovoltaic panel 200, the contact area between the first opening groove 111 and the photovoltaic panel 200 is also larger, and the first opening groove 111 can limit the non-opening side of the photovoltaic panel 200, thereby improving the connection reliability.

[0099] In other embodiments, the second connection portion 21 includes a second opening groove 211 opening along the first direction X away from the female docking portion 22 , and the second opening groove 211 is used to accommodate a portion of another photovoltaic panel 200 to connect with the other photovoltaic panel 200 .

[0100] Similarly, the opening of the second connecting portion 21 is arranged along the first direction X away from the female docking portion 22 , that is, the side away from the female docking portion 22 forms an opening, and the side close to the female docking portion 22 forms the bottom wall of the groove.

[0101] By providing the second opening groove 211 for accommodating a portion of the photovoltaic panel 200 so as to be connected to the photovoltaic panel 200, the contact area between the second opening groove 211 and the photovoltaic panel 200 is also larger, and the second opening groove 211 can limit the non-opening side of the photovoltaic panel 200, thereby improving the connection reliability.

[0102] In other embodiments, the first connection portion 11 includes a first opening groove 111 that opens along the first direction X away from the male docking portion 12, and the first opening groove 111 is used to accommodate a portion of the photovoltaic panel 200 to be connected to the photovoltaic panel 200, and the second connection portion 21 includes a second opening groove 211 that opens along the first direction X away from the female docking portion 22, and the second opening groove 211 is used to accommodate a portion of another photovoltaic panel 200 to be connected to the other photovoltaic panel 200.

[0103] Please continue reading Figure 2 According to some embodiments of the present application, the photovoltaic panel connection structure 100 further includes a sealant 40 filled between the first frame 10 and the second frame 20 .

[0104] The sealant 40 refers to a colloid with a sealing function. When the male docking portion 12 of the first frame 10 and the female docking portion 22 of the second frame 20 are plugged into place, the gap between the two can be sealed by filling the sealant therebetween. Of course, the sealant can also be applied to the first frame 10 and the second frame 20 in advance, and after the male docking portion 12 of the first frame 10 and the female docking portion 22 of the second frame 20 are plugged into place, a seal can be formed.

[0105] The method of sealing the first frame 10 and the second frame 20 by filling the sealant 40 between the first frame 10 and the second frame 20 is simple and reliable.

[0106] Specifically, the sealant 40 may be filled in the outer gap between the first frame 10 and the second frame 20 .

[0107] Combination Figure 4 According to some embodiments of the present application, the photovoltaic panel connection structure 100 may include a plurality of first frames 10 and a plurality of second frames 20, each first frame 10 and each second frame 20 forming a frame group, the first frame 10 and the second frame 20 of each frame group are arranged opposite to each other, and the first connection portion 11 and the second connection portion 12 of each frame group are used to connect with at least two opposite sides of the same photovoltaic panel 200. At least two frame groups are arranged adjacent to each other along the first direction, and the first frame 10 of one of the two adjacent frame groups is adjacent to the second frame 20 of the other frame group, so that the male docking portion 12 of the first frame 10 and the female docking portion 22 of the second frame 20 are plugged into each other.

[0108] By providing a frame group connected to the photovoltaic panels 200 , the connection between the photovoltaic panels 200 through the photovoltaic panel connection structure 100 is made simpler and can be applicable to connection operations of a large number of photovoltaic panels 200 .

[0109] See also Figure 1~Figure 3In addition, a photovoltaic assembly 300 is also provided in an embodiment of the present application, comprising a plurality of photovoltaic panels 200 and the photovoltaic panel connection structure 100 in any of the above embodiments.

[0110] Specifically, the first connection portion 11 in the photovoltaic panel connection structure 100 is used to connect to the photovoltaic panel 200 , and the second connection portion 21 is used to connect to another photovoltaic panel 200 .

[0111] The photovoltaic panel 200 may include photovoltaic glass, and may also include a cell sheet, a back sheet, and the like.

[0112] By plugging the male docking part 12 and the female docking part 22 into each other, the connection structure between the first frame 10 and the second frame 20 can be simplified, and the two can be quickly matched. Secondly, when the photovoltaic panel 200 connected to the first frame 10 and the photovoltaic panel 200 connected to the second frame 20 are subjected to different wind loads, since the contact surface 30 of one of the male docking part 12 and the female docking part 22 is in contact with the contact protrusion 31 of the other of the male docking part 12 and the female docking part 22 along the second direction, and the second direction is consistent with the direction of the wind load, the load can be transferred through the contact between the contact surface 30 and the contact protrusion 31, thereby enabling the first frame 10 and the second frame 20 to deform cooperatively, thereby reducing the enlargement of the gap between the first frame 10 and the second frame 20 and reducing the risk of failure of the waterproof and airproof functions.

[0113] In addition, since the male docking part 12 and the female docking part 22 are in contact with each other through the contact surface 30 and the contact protrusion 31, the contact area is reduced. When subjected to different wind loads, the abnormal noise caused by movement friction between the male docking part 12 and the female docking part 22 can also be reduced.

[0114] Please continue reading Figure 3 and Figure 4 In addition, a photovoltaic curtain wall is also provided in an embodiment of the present application, including a supporting body and the photovoltaic assembly 300 in any of the above embodiments, and a photovoltaic panel connection structure 100 is connected to the body.

[0115] The supporting body refers to a main structure that can support the photovoltaic assembly 300. The supporting assembly can be composed of multiple components, which can be specifically connected into a supporting frame or a supporting seat.

[0116] The photovoltaic panel connection structure 100 can be connected to a part of the structure of the support body, and then reliably supported by the support body. Specifically, the photovoltaic assembly 300 can be supported on the top of the support body in the vertical direction, or on the side of the support body.

[0117] By plugging the male docking part 12 and the female docking part 22 into each other, the connection structure between the first frame 10 and the second frame 20 can be simplified, and the two can be quickly matched. Secondly, when the photovoltaic panel 200 connected to the first frame 10 and the photovoltaic panel 200 connected to the second frame 20 are subjected to different wind loads, since the contact surface 30 of one of the male docking part 12 and the female docking part 22 is in contact with the contact protrusion 31 of the other of the male docking part 12 and the female docking part 22 along the second direction, and the second direction is consistent with the direction of the wind load, the load can be transferred through the contact between the contact surface 30 and the contact protrusion 31, thereby enabling the first frame 10 and the second frame 20 to deform cooperatively, thereby reducing the enlargement of the gap between the first frame 10 and the second frame 20 and reducing the risk of failure of the waterproof and airproof functions.

[0118] In addition, since the male docking part 12 and the female docking part 22 are in contact with each other through the contact surface 30 and the contact protrusion 31, the contact area is reduced. When subjected to different wind loads, the abnormal noise caused by movement friction between the male docking part 12 and the female docking part 22 can also be reduced.

[0119] See also Figure 5 and Figure 6 According to some embodiments of the present application, the photovoltaic curtain wall further includes at least one elastic buckle 400, and the first frame 10 is connected to the main body via at least one elastic buckle 400.

[0120] The elastic buckle 400 refers to an elastic buckle structure, and its connection with the main body is an elastic snap connection. The specific structural form of the elastic buckle 400 is not limited, and it can include at least one elastic clamp arm and at least one fixed clamp arm, and the elastic clamp arm and the fixed clamp arm are arranged opposite to each other to form an elastic clamp groove therebetween, and the first frame 10 and the main body can be inserted into the elastic clamp groove for connection. The elastic buckle 400 can also include at least two elastic clamp arms, and the two elastic clamp arms are arranged opposite to each other to form an elastic clamp groove therebetween to clamp the first frame 10 and the main body.

[0121] In the related art, bolts are often used to connect the frames, but the operating space in the frame is small, which makes the installation efficiency low. However, the present application sets the first frame 10 to be connected to the main body through the elastic buckle 400, so that the installation between the first frame 10 and the main body is not limited by the operating space of the first frame 10, and the first frame 10 and the main body can be installed efficiently, which shortens the construction period.

[0122] In other embodiments, the second frame 20 may also be connected to the main body via at least one elastic buckle 400 .

[0123] It should be noted that the first frame 10 and the second frame 20 can be connected to the main body through different elastic buckles 400 respectively, or can be connected to the main body through the same elastic buckle 400.

[0124] Similarly, by providing the second frame 20, it can also be connected to the main body through the elastic buckle 400, so that the second frame 20 and the main body can be efficiently installed, shortening the construction period.

[0125] In other embodiments, the first frame 10 is connected to the main body via at least one elastic buckle 400 , and the second frame 20 may also be connected to the main body via at least one elastic buckle 400 .

[0126] Please continue reading Figure 6 According to some embodiments of the present application, the first frame 10 also includes a first extension portion 13 arranged opposite to the first connecting portion 12 along the second direction Z, and the first extension portion 13 extends along the first direction X toward a side away from the male docking portion 12, and the first extension portion 13 is connected to the main body through at least one elastic buckle 400.

[0127] The first extension portion 13 of the embodiment of the present application extends along the first direction X to a side away from the male docking portion 12 . The first extension portion 13 may be an extended rib or other extended structures.

[0128] Since the first extension portion 13 and the first connection portion 12 are located on the same side and are arranged opposite to the first connection portion 12 along the second direction Z, when connected to the main body, it will not affect the connection between the male docking portion 12 and the female docking portion 22, nor the connection between the first connection portion 12 and the photovoltaic panel 200, and there is enough space left for connecting to the main body through the elastic buckle 400, thereby simplifying the connection operation.

[0129] In other embodiments, the second frame 20 also includes a second extension portion 23 arranged opposite to the second connecting portion 21 along the second direction Z, the second extension portion 23 extends along the first direction X toward a side away from the female docking portion 22, and the second extension portion 23 is connected to the main body via at least one elastic buckle 400.

[0130] Likewise, the second extension portion 23 may be an extended rib or other extended structures.

[0131] Since the second extension portion 23 and the second connection portion 21 are located on the same side and are arranged opposite to the second connection portion 21 along the second direction Z, when connected to the main body, it will not affect the connection between the female docking portion 22 and the male docking portion 12, nor will it affect the connection between the second connection portion 21 and the photovoltaic panel 200, and there is enough space left for connecting to the main body through the elastic buckle 400, thereby simplifying the connection operation.

[0132] In other embodiments, the first frame 10 also includes a first extension portion 13 arranged opposite to the first connecting portion 12 along the second direction Z, the first extension portion 13 extends along the first direction X toward a side away from the male docking portion 12, the first extension portion 13 is connected to the main body through at least one elastic clip 400, and the second frame 20 also includes a second extension portion 23 arranged opposite to the second connecting portion 21 along the second direction Z, the second extension portion 23 is connected to the main body through at least one elastic clip 400.

[0133] Please continue reading Figure 6 According to some embodiments of the present application, the main body includes at least one C-shaped purlin 500, and each C-shaped purlin 500 includes a web 510 and a flange 520 connected to one side of the web 510. In the second direction Z, the flange 520 of one C-shaped purlin 500 is in contact with the side of the first extension portion 13 facing away from the first connecting portion 11, and is connected to the first extension portion 13 through at least one elastic buckle 400.

[0134] Purlins are transverse bending members, usually composed of two parallel flanges and a web connecting the two flanges. C-shaped purlins 500 refer to purlins with a C-shaped transverse cross-section, so that the two flanges 520 are arranged on the same side of the web 510, and the ends away from the web 510 have bent portions bent toward each other.

[0135] Since the flange plate 520 of the C-shaped purlin 500 is in contact with the side of the first extension portion 13 facing away from the first connection portion 11, the first extension portion 13 can reliably support the first frame 10, and the flange plate 520 of the C-shaped purlin 500 has a relatively simple structure. Therefore, the connection operation is further simplified by connecting it to the first extension portion 13 through at least one elastic buckle 400.

[0136] In some other embodiments, in the second direction Z, the flange plate 520 of another C-shaped purlin 500 is in contact with the side of the second extension portion 23 facing away from the second connection portion 21 , and is connected to the second extension portion 23 via at least one elastic buckle 400 .

[0137] Since the flange plate 520 of the C-shaped purlin 500 is in contact with the side of the second extension portion 23 facing away from the second connection portion 21, the second extension portion 23 can reliably support the second frame 20, and the flange plate 520 of the C-shaped purlin 500 has a relatively simple structure, the connection operation is further simplified by connecting it to the second extension portion 23 through at least one elastic buckle 400.

[0138] In other embodiments, in the second direction Z, the flange plate 520 of one C-shaped purlin 500 is in contact with the side of the first extension portion 13 facing away from the first connecting portion 11, and is connected to the first extension portion 13 through at least one elastic buckle 400, and the flange plate 520 of another C-shaped purlin 500 is in contact with the side of the second extension portion 23 facing away from the second connecting portion 21, and is connected to the second extension portion 23 through at least one elastic buckle 400.

[0139] Please continue reading Figure 6 According to some embodiments of the present application, the flange plate 520 of each C-shaped purlin 500 includes a plate body 521 and a bent portion 522, one end of the plate body 521 is connected to the web 510, and the other end of the plate body 521 is connected to the bent portion 522, and an angle is formed between the plate body 521 and the bent portion 522. Each elastic clip 400 includes a first elastic snap-fit ​​groove 410 and a second elastic snap-fit ​​groove 420 that are connected. The plate body 521 of one C-shaped purlin 500 is in contact with the first extension portion 13, and at least a portion of the plate body 521 and at least a portion of the first extension portion 13 are clamped together in the first elastic snap-fit ​​groove 410 of at least one elastic clip 400, and the bent portion 522 is clamped in the second elastic snap-fit ​​groove 420.

[0140] The plate body 521 is the main part of the flange plate 520, and can fit with the first extension portion 13 or the second extension portion 23 to support the first frame 10 or the second frame 20. The bending portion 522 is as described above, and will not be described again.

[0141] An elastic snap-fit ​​groove means that when an object is placed in the groove, it can be elastically snap-fitted in the groove.

[0142] Since the plate body 521 of the C-shaped purlin 500 is in contact with the first extension portion 13, the plate body 521 and the first extension portion 13 both extend along the first direction X. When they are clamped together in the first elastic clamping groove 410, the first extension portion 13 can be limited along the second direction Z, so that the first frame 10 is not easy to move relative to the main body in the second direction Z. At the same time, an angle is formed between the plate body 521 and the bending portion 522. When the bending portion 522 is clamped in the second elastic clamping groove 420, the bending portion 522 can limit the elastic buckle 400 in the direction intersecting with the second direction Z (including the first direction X). Therefore, under the action of the elastic buckle 400, the first frame 10 is not easy to move relative to the main body in the direction intersecting with the second direction Z. Therefore, by providing the first elastic snap-fit ​​groove 410 and the second elastic snap-fit ​​groove 420 , the movement of the first frame 10 and the photovoltaic panel 200 connected thereto under different forces can be effectively fixed, thereby improving the reliability of the photovoltaic curtain wall.

[0143] In other embodiments, the plate body 521 of another C-shaped purlin 500 is fitted with the second extension portion 23, and at least a portion of the plate body 521 and at least a portion of the second extension portion 23 are clamped together in the first elastic clamping groove 410 of at least one elastic buckle 400, and the bending portion 522 is clamped in the second elastic clamping groove 420.

[0144] Similarly, since the plate body 521 of the C-shaped purlin 500 is in contact with the second extension portion 23, the plate body 521 and the second extension portion 23 both extend along the first direction X. When they are clamped together in the first elastic clamping groove 410, the second extension portion 23 can be limited along the second direction Z, so that the second frame 20 is not easy to move relative to the main body in the second direction Z. At the same time, an angle is formed between the plate body 521 and the bending portion 522. When the bending portion 522 is clamped in the second elastic clamping groove 420, the bending portion 522 can limit the elastic buckle 400 in the direction intersecting with the second direction Z (including the first direction X), and then under the action of the elastic buckle 400, the second frame 20 is not easy to move relative to the main body in the direction intersecting with the second direction Z. Therefore, by providing the first elastic snap-fit ​​groove 410 and the second elastic snap-fit ​​groove 420 , the movement of the second frame 20 and the photovoltaic panel 200 connected thereto under different forces can be effectively fixed, thereby improving the reliability of the photovoltaic curtain wall.

[0145] In other embodiments, the flange plate 520 of each C-shaped purlin 500 includes a plate body 521 and a bent portion 522, one end of the plate body 521 is connected to the web 510, and the other end of the plate body 521 is connected to the bent portion 522, and an angle is formed between the plate body 521 and the bent portion 522. Each elastic clip 400 includes a first elastic snap-fit ​​groove 410 and a second elastic snap-fit ​​groove 420 that are connected. The plate body 521 of one C-shaped purlin 500 is fitted with the first extension portion 13, and at least a portion of the plate body 521 and at least a portion of the first extension portion 13 are clamped together in the first elastic snap-fit ​​groove 410 of at least one elastic clip 400, and the bent portion 522 is clamped in the second elastic snap-fit ​​groove 420. The plate body 521 of the other C-shaped purlin 500 is fitted with the second extension portion 23 , and at least a portion of the plate body 521 and at least a portion of the second extension portion 23 are clamped together in the first elastic clamping groove 410 of at least one elastic buckle 400 , and the bent portion 522 is clamped in the second elastic clamping groove 420 .

[0146] In addition, a photovoltaic power generation device is provided in an embodiment of the present application, including the photovoltaic curtain wall in any of the above embodiments.

[0147] Specifically, the photovoltaic power generation device may also include a power controller, an inverter, etc. electrically connected to the photovoltaic curtain wall.

[0148] By plugging the male docking part 12 and the female docking part 22 into each other, the connection structure between the first frame 10 and the second frame 20 can be simplified, and the two can be quickly matched. Secondly, when the photovoltaic panel 200 connected to the first frame 10 and the photovoltaic panel 200 connected to the second frame 20 are subjected to different wind loads, since the contact surface 30 of one of the male docking part 12 and the female docking part 22 is in contact with the contact protrusion 31 of the other of the male docking part 12 and the female docking part 22 along the second direction, and the second direction is consistent with the direction of the wind load, the load can be transferred through the contact between the contact surface 30 and the contact protrusion 31, thereby enabling the first frame 10 and the second frame 20 to deform cooperatively, thereby reducing the enlargement of the gap between the first frame 10 and the second frame 20 and reducing the risk of failure of the waterproof and airproof functions.

[0149] In addition, since the male docking part 12 and the female docking part 22 are in contact with each other through the contact surface 30 and the contact protrusion 31, the contact area is reduced. When subjected to different wind loads, the abnormal noise caused by movement friction between the male docking part 12 and the female docking part 22 can also be reduced.
