Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0043] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0044] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0045] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

[0048] Next, the photovoltaic module frame and photovoltaic module of the present application are described through embodiments.

[0049] Figure 1 is a three-dimensional schematic diagram of a photovoltaic module in an embodiment, Figure 2 yes Figure 1 The enlarged schematic diagram of point A in the middle. Figure 3 is a three-dimensional schematic diagram of a photovoltaic module frame in an embodiment, Figure 4 yes Figure 3 A magnified schematic diagram of point B in the middle. Figures 1 to 4As shown, the photovoltaic module frame includes a first frame 110, a second frame 120, a third frame 130, a fourth frame 140, a corner code 150 and a rubber strip 160. Specifically, the first frame 110 and the third frame 130 are arranged relative to each other in the second direction D2, and both extend along the first direction D1. The second frame 120 and the fourth frame 140 are arranged relative to each other in the first direction D1, and both extend along the second direction D2. The corner code 150 is used to sequentially connect the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140 end to end. Figure 1 There are four corner codes 150, and only three of them can be observed due to the viewing angle.

[0050] The first frame 110 and the third frame 130 have grooves for accommodating the laminate 170. The first frame 110 is taken as an example for further description. The first frame 110 has a groove 111 (such as Figure 4 The groove 111 extends along the first direction D1, the opening of the groove 111 faces the laminate 170, one side of the laminate 170 is inserted into the groove 111 through the opening, and the groove 111 and the laminate 170 can be connected by an adhesive in the groove 111, so that the first frame 110 is connected to one side of the laminate 170. Similarly, the third frame 130 is connected to one side of the laminate 170 in the above manner.

[0051] The top surface of the second frame 120 and the top surface of the fourth frame 140 are located below the laminate 170. The fourth frame 140 is taken as an example for further explanation. Figure 2 and Figure 4 As shown, the top surface 141 of the fourth frame 140 is located below the laminate 170, and a plurality of adhesive strips 160 are disposed between the top surface 141 and the laminate 170, and the adhesive strips 160 connect the fourth frame 140 and the laminate 170. Similarly, a plurality of adhesive strips 160 are disposed between the top surface of the second frame 120 and the laminate 170, and the adhesive strips 160 connect the second frame 120 and the laminate 170. The material of the adhesive strips 160 may be silicone.

[0052] like Figure 2As shown, the second frame 120 and the fourth frame 140 of the present application do not have the A surface in the traditional photovoltaic module frame and the B surface is not higher than the top surface of the frame, so that the fourth frame 140 does not block the side surface 171 of the laminate located above it, and similarly, the second frame 120 does not block the side surface of the laminate located above it. When the photovoltaic module is in a tilted state, one of the second frame 120 and the fourth frame 140 is located below (that is, one of them is closer to the ground). Since the side surface of the laminate located above the second frame 120 and the fourth frame 140 is exposed and the top surface of the second frame 120 and the top surface of the fourth frame 140 are located below the laminate 170, dust and rainwater cannot accumulate on the surface of the laminate 170. In addition, exposing the side surface of the laminate can also prevent water vapor from corroding the laminate because water vapor cannot accumulate on the side surface of the laminate.

[0053] refer to Figure 5 and Figure 6 As shown, in one embodiment, the top surface of the second frame 120 has a plurality of toothed strips arranged adjacent to each other in the first direction D1, and the toothed strips can increase the contact area between the adhesive strip 160 and the top surface, thereby improving the connection stability between the laminate 170 and the second frame 120. Similarly, the top surface of the fourth frame 140 can also have a plurality of toothed strips arranged adjacent to each other in the first direction D1.

[0054] refer to Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, from Figure 1 Observed from the top view angle in , the top surface 141 of the fourth frame 140 is aligned with the side of the laminate 170 away from the side of the laminate 171, or the top surface 141 is protruding from the side of the laminate 171 away from the side of the laminate 170 (i.e., the projection of the side of the laminate 171 in the top view direction falls on the top surface 141). In this way, the fourth frame 140 can protect the laminate 170 to prevent the side of the laminate 171 from colliding with the outside world. Similarly, the second frame 120 can also have the above-mentioned features. For related descriptions, please refer to the description of the fourth frame 140, which will not be expanded.

[0055] Continue to refer Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the projection of the laminate 170 in the thickness direction completely covers the adhesive strip 160 , that is, the adhesive strip 160 cannot be observed from a top view, which can improve the aesthetics of the photovoltaic module.

[0056] refer to Figure 4As shown, in one embodiment, the photovoltaic module frame also includes a plurality of stoppers 180, and the stoppers 180 are elastic. A plurality of stoppers 180 are located on the top surface of the second frame 120 and the top surface of the fourth frame 140. In the process of connecting the photovoltaic module frame with the laminate 170, the stoppers 180 are located between the laminate 170 and the second frame 120, and between the laminate 170 and the fourth frame 140. When the adhesive strip 160 is squeezed by the laminate 170, the adhesive strip 160 will be deformed (i.e., overflowing glue). The stoppers 180 can control the amount of overflowing glue to prevent the adhesive strip from overflowing to a position that can be observed from a top view, which can improve the aesthetics of the photovoltaic module. In addition, the stoppers 180 can also control the gap size between the laminate 170 and the second frame 120 and the fourth frame 140. The stoppers 180 can include any of foam, EPDM, and other rubbers.

[0057] refer to Figure 5 and Figure 6 As shown, in one embodiment, the second frame 120 has a convex rib 122, which is located on the top surface 121, and the extension direction of the convex rib 122 is the same as the extension direction of the second frame 120. Preferably, the convex rib 122 is connected to the side plate 123 (also referred to as the B surface in the art) of the second frame 120. The height of the convex rib 122 is 1 to 3 mm, such as 1.5 mm, 2 mm or 2.5 mm, and the width of the convex rib 122 is 1 to 2 mm, such as 1.5 mm. The convex rib 122 abuts against the bottom surface of the laminate 170. The convex rib 122 can replace the stop block 180. In addition, dust may accumulate in the gap between the stop block 180 and the laminate 170, and the convex rib 122 seals the opening of the gap between the second frame 120 and the laminate 170 toward the outside, thereby preventing dust from accumulating in the above-mentioned gap. Similarly, the fourth frame may also have convex ribs. For related descriptions, please refer to the description of the second frame 120, which will not be elaborated here.

[0058] In one embodiment, the end surface of the first frame is at a right angle to its own extension direction, the end surface of the second frame is at a right angle to its own extension direction, the end surface of the third frame is at a right angle to its own extension direction, and the end surface of the fourth frame is at a right angle to its own extension direction. Figure 7 As shown, the fourth frame 140 has two end surfaces 142 in the second direction D2, and the two end surfaces 142 are perpendicular to the second direction D2. Similarly, the first frame 110 has two end surfaces in the first direction D1, and the two end surfaces are perpendicular to the first direction D1. Figure 8 and Fig. 9As described, the corner code 150 has a first plug-in portion 151 and a second plug-in portion 152. The first plug-in portion 151 is inserted into the cavity of the first frame 110, and the second plug-in portion 152 is inserted into the cavity of the fourth frame 140. The first docking surface 153 is in contact and alignment with the end surface of the first frame 110 close to the fourth frame 140, and the second docking surface 154 is in contact and alignment with the end surface of the fourth frame 140 close to the first frame 110, so that the first frame 110 and the fourth frame 140 are connected using the corner code 150.

[0059] refer to Figure 8 As shown, in one embodiment, the corner code 150 has a wrap angle 155, and the wrap angle 155 is aligned with the groove of the corresponding frame. Figure 3 and Figure 8 As shown, the wrap angle 155 is aligned with the groove 111. After the alignment, the wrap angle 155 is connected to the groove 111. Preferably, the cross section of the wrap angle 155 is the same as the cross section of the groove 111. In this way, the aesthetics of the photovoltaic module can be improved.

[0060] refer to Figure 8 As shown, in one embodiment, the corner 155 has a first side wall 155a and a second side wall 155b connected to each other, the first side wall 155a is aligned with the bottom surface of the groove of the corresponding frame, and the second side wall 155b is abutted against the side surface of the laminate located on the adjacent frame. Figure 2 , Figure 3 and Figure 8 As shown, the first side wall 155a is aligned with the bottom surface of the groove 111, the second side wall 155b is adjacent to the fourth frame 140, the laminate side 171 is located above the fourth frame 140, and the second side wall 155b is in contact with the laminate side 171. When the photovoltaic module is in an inclined state in the first direction D1, the second side wall 155b can apply a supporting force to the laminate side 171, thereby preventing the laminate 170 from sliding downward.

[0061] refer to Figure 8 and Fig. 9 As shown, the second side wall 155b has four through holes 190, and the through holes 190 can be used to drain the accumulated water that may accumulate in the corner 155. It can be understood that the number of through holes is not limited to four and can be set according to needs.

[0062] In one embodiment, the angle bracket is an integrally formed part, for example, integrally formed by a die-casting process, or a combination of several parts. The material of the angle bracket may include aluminum alloy or highly weather-resistant non-metal (such as nylon, fiberglass).

[0063] refer to Fig. 9As shown, the top corner 156 of the corner code 150 is chamfered. Preferably, the chamfer is an arc surface, so that the top corner 156 can avoid scratching construction workers.

[0064] refer to Figure 1 , Fig.10 and Fig.11 The photovoltaic module can be assembled as follows. Use adhesive strips to connect the laminate 170, the second frame 120, and the fourth frame 140; insert two corner brackets 150 into the two ends of the first frame 110 (such as Fig.10 and Fig.11 As shown), insert the two corner codes 150 at both ends of the third frame 130; insert the two corner codes at both ends of the first frame 110 into one end of the second frame 120 and one end of the fourth frame 140, and insert the two corner codes at both ends of the third frame 130 into the other end of the second frame 120 and the other end of the fourth frame 140.
