Description

Technical Field

[0001] The present application relates to the technical field of solar cells, and in particular to a photovoltaic frame and a photovoltaic module. Background Art

[0002] Solar photovoltaic modules are devices that convert light energy into electrical energy through photovoltaic cells. They primarily consist of a photovoltaic laminate and a frame. The frame is installed around the periphery of the photovoltaic laminate and secures the laminate to a photovoltaic support frame, enabling the modules to be used in photovoltaic scenarios such as large-scale ground-based power stations and building rooftops. The frame generally consists of four end-to-end strip frames. Conventionally, the ends of two adjacent strip frames are connected using an L-shaped angle bracket. Bolts are then used to securely connect the perpendicular ends of the L-shaped angle bracket to the adjacent strip frames, thereby achieving a fixed connection between the two strip frames.

[0003] Currently, the frame includes a corner code cavity for accommodating the corner code and a mounting groove for accommodating the laminate. The corner code cavity is located below the mounting groove in the height direction of the frame. When the edge side of the laminate is placed in the mounting groove, the presence of the corner code cavity causes the backlight surface of the laminate to be too far away from the mounting surface of the photovoltaic module (such as the roof surface). When the backlight surface of the laminate needs to be bonded and locked to the mounting surface, the corner code cavity interferes with the bonding and locking between the backlight surface of the laminate and the mounting surface, resulting in excessive adhesive filling between the backlight surface of the laminate and the mounting surface, making the bonding operation difficult. Utility Model Content

[0004] Based on this, it is necessary to provide a photovoltaic frame and photovoltaic module to address the problem that the existing corner code cavity will interfere with the bonding and locking between the backlight surface of the laminate and the installation plane.

[0008] The first side plate and the second side plate are both connected to the bottom plate and the top plate. The second side plate is located on a side close to the opening. The mounting groove and the accommodating cavity are respectively formed on both sides of the second side plate.

[0011] In one embodiment, the first extension extends into the mounting slot and is inclined from the second side plate toward the opening; and / or

[0012] The second extension portion extends into the installation slot and is inclined from the second side plate toward the opening.

[0013] In one embodiment, the frame body is further provided with at least one connecting protrusion, which protrudes into the accommodating cavity and can cooperate with the connecting member.

The accommodating cavity is used to accommodate a connector (such as an L-shaped angle code), and two adjacent photovoltaic frames are fixedly connected through the connector. The photovoltaic frame provided by the present application has a accommodating cavity located on the side of the mounting groove away from the opening. When the laminate needs to be fixed to the mounting plane through the photovoltaic frame, the accommodating cavity will not interfere with the bonding and locking between the backlight surface of the laminate and the mounting plane.

[0038] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0039] In some embodiments, see Figure 1 and Figure 2 As shown, the composition of the photovoltaic module 300 specifically includes a laminate 200 and a photovoltaic frame 100 installed on the periphery of the laminate 200, and the laminate 200 includes a cell layer, a film and a cover plate. Among them, the cell layer includes a plurality of cell strings connected in parallel, and the cell string includes a plurality of cell cells arranged in series. As an optional technical solution of the present application, the cell type used in the present application can be one or more of a heterojunction cell (Heterojunction with Intrinsic Thin-layer, HIT), a back contact cell (Back Contact, BC), a Passivated Emitter Rear Cell (PERC), a tunnel oxide passivated contact cell (Tunnel Oxide Passivated Contact, TOPCON), and a perovskite cell (PSC).

[0040] At present, a photovoltaic frame 100 is usually used to fix the laminate 200 on a photovoltaic support frame so that the photovoltaic module 300 can be used in photovoltaic scenarios such as large-scale ground power stations and building roofs. The photovoltaic frame 100 generally includes four strip frames connected end to end. When the ends of two adjacent strip frames are conventionally connected, an L-shaped angle code is usually used, and then the two ends of the L-shaped angle code that are perpendicular to each other are fixedly connected to the two adjacent strip frames by bolts, thereby achieving a fixed connection between the two strip frames. The photovoltaic frame 100 includes a accommodating cavity 112 for accommodating the L-shaped angle code and a mounting groove 111 for accommodating the laminate 200. In the height direction of the photovoltaic frame 100, the accommodating cavity 112 is located below the mounting groove 111. When the edge side of the laminate 200 is placed in the installation groove 111, due to the presence of the accommodating cavity 112, the distance between the backlight surface of the laminate 200 and the installation plane of the photovoltaic module 300 (such as the roof surface of the building) is too large. When the backlight surface of the laminate 200 needs to be bonded and locked to the installation plane, the accommodating cavity 112 will interfere with the bonding and locking between the backlight surface of the laminate 200 and the installation plane. Too much adhesive needs to be filled between the backlight surface of the laminate 200 and the installation plane, and the bonding operation is difficult.

[0041] For the above questions, see Figure 1-Figure 3 As shown, the present application provides a photovoltaic frame 100, which includes a frame 110 and is used to install a laminate 200. The photovoltaic frame 100 is wrapped around the edge of the laminate 200, such as by snapping the edge of the photovoltaic frame 100 to the photovoltaic frame 100, so as to achieve the installation and fixation of the photovoltaic frame 100 to the laminate 200.

[0042] The frame 110 is provided with a mounting groove 111, a receiving cavity 112 and a glue overflow groove 113. The mounting groove 111 and the receiving cavity 112 are both constructed to extend longitudinally along the length direction of the photovoltaic frame 100. Figure 3 As shown, the mounting groove 111 and the accommodating cavity 112 extend in the direction A. Figure 3 The direction A shown runs through the photovoltaic frame 100. The mounting groove 111 has an opening 1111 for the edge side of the laminate 200 to enter the mounting groove 111. The edge side of the laminate 200 enters the mounting groove 111 through the opening 1111 and is bonded and fixed to the photovoltaic frame 100. Figure 4As shown, the accommodating cavity 112 is used to accommodate the connector 120, and the accommodating cavity 112 is located on the side of the mounting groove 111 away from the opening 1111. For example, the connector 120 is an L-shaped angle bracket, one end of which is inserted into the accommodating cavity 112 of one frame 110, and the other end of the L-shaped angle bracket is inserted into the accommodating cavity 112 of the other frame 110. The L-shaped angle bracket is used to securely connect two adjacent photovoltaic frames 100. The overflow glue groove 113 is connected to the mounting groove 111 and is used to control the overflow of the adhesive during the bonding process of the laminate 200.

[0043] In the photovoltaic frame 100 described above, because the accommodating cavity 112 is located on the side of the mounting groove 111 facing away from the opening 1111, when the laminate 200 needs to be fixed to the mounting surface through the photovoltaic frame 100, the accommodating cavity 112 does not interfere with the adhesive bonding and locking between the backlight surface of the laminate 200 and the mounting surface. The distance between the backlight surface of the laminate 200 and the mounting surface is relatively small, which reduces the amount of adhesive required between the backlight surface of the laminate 200 and the mounting surface, simplifying the adhesive bonding and locking operation between the laminate 200 and the mounting surface. Furthermore, the adhesive layer between the backlight surface of the laminate 200 and the mounting surface is relatively thin, which can prevent the adhesive layer from aging, delamination, and other undesirable phenomena during long-term use.

[0044] In one embodiment, continue to refer to Figure 5 As shown, the frame 110 includes a bottom plate 114, a top plate 115, a first side plate 116 and a second side plate 117. The bottom plate 114 and the top plate 115 are arranged opposite to each other in a first direction. Figure 5 As shown in FIG. 1 , the first side plate 116 and the second side plate 117 are arranged relative to each other in the second direction. Figure 5 The C direction shown is spaced relative to each other, wherein the first direction and the second direction are respectively perpendicular to the length direction of the photovoltaic frame 100, and the bottom plate 114 is the surface close to the installation plane. The first side plate 116 and the second side plate 117 are both connected to the bottom plate 114 and the top plate 115. The second side plate 117 is located on the side close to the opening 1111. The second side plate 117 is respectively formed with a mounting groove 111 and a receiving cavity 112 on both sides. In other words, refer to Figure 5 As shown, the second side panel 117, the first side panel 116, the bottom panel 114 and the top panel 115 are jointly arranged to form a receiving cavity 112, and the second side panel 117, the bottom panel 114, the top panel 115 and the opening 1111 are arranged to form a mounting groove 111, and the opening 1111 allows the edge side of the laminate 200 to enter the mounting groove 111 and be bonded and fixed to the photovoltaic frame 100.

[0045] In the photovoltaic frame 100, the accommodating cavity 112 is located on the side away from the opening 1111, and the accommodating cavity 112 and the mounting groove 111 are respectively located at Figure 5 The left and right sides shown in FIG. 1 can reduce the overall height of the photovoltaic frame 100, reduce the overall mass of the photovoltaic frame 100, and facilitate the weight reduction design of the photovoltaic module 300. Figure 5 For example, the distance between the surface of the bottom plate 114 close to the mounting plane and the surface of the top plate 115 away from the mounting plane is H1, 5mm≤H1≤10mm, such as H1 can be any one of 5mm, 6mm, 7mm, 8mm, 9mm, 10mm to accommodate the connector 120; the opening 1111 is in the first direction ( Figure 5 The height (in the direction B shown) of the connector 120 is H2, and 1mm≤H2≤5mm. For example, H2 can be any one of 1mm, 2mm, 3mm, 4mm, and 5mm to accommodate the installation and entry of the laminate 200. It should be noted that H1 and H2 are not limited to the above ranges and specific values. It is only necessary that H1 can accommodate the accommodation of the connector 120 and H2 can accommodate the installation and entry of the laminate 200. This application does not impose any restrictions on the specific ranges and values ​​of H1 and H2.

[0046] In one embodiment, see Figure 2 、 Figure 3 and Figure 5 As shown, the top plate 115 includes a first extension portion 1151 extending from the second side plate 117 toward the side of the opening 1111. The first extension portion 1151 and the second side plate 117 are surrounded by a guide groove 118, and the guide groove 118 is connected to the installation groove 111. When the edge side of the laminate 200 enters the installation groove 111 through the opening 1111, a preset amount of adhesive can be poured into the installation groove 111. The guide groove 118 guides the flow of the adhesive, and the adhesive flows evenly and is applied to various areas on the edge side of the laminate 200, thereby improving the bonding strength of the edge side of the laminate 200, thereby improving the bonding and fixing reliability of the laminate 200 to the photovoltaic frame 100.

[0047] Also, see Figure 2 、 Figure 3 and Figure 5As shown, the top plate 115 further includes a second extension portion 1152 extending from the second side plate 117 toward the side of the opening 1111. The second extension portion 1152 is connected to the end of the first extension portion 1151 away from the second extension portion 1152. The second extension portion 1152 and the first extension portion 1151 are surrounded by a glue overflow groove 113, which is connected to the mounting groove 111. The glue overflow groove 113 is used to control glue overflow during the bonding process of the laminate 200. Since the glue overflow groove 113 is formed on one side of the top plate 115, during the process of bonding the laminate 200, the glue overflow groove 113 can prevent excessive adhesive from overflowing from the side of the top plate 115 to the light-receiving surface of the laminate 200, which would burden the laminate 200 with cleaning adhesive. In addition, since the glue overflow groove 113 is not provided on the side of the bottom plate 114, it is possible to judge whether there is sufficient adhesive for bonding the laminate 200 by observing whether there is adhesive overflow on the side of the bottom plate 114, thereby ensuring the bonding strength between the photovoltaic frame 100 and the laminate 200.

[0048] Further, see Figure 5 As shown, the first extension 1151 extends into the mounting groove 111 and is inclined from the second side plate 117 toward the opening 1111; and / or the second extension 1152 extends into the mounting groove 111 and is inclined from the second side plate 117 toward the opening 1111. In one embodiment, only the first extension 1151 extends into the mounting groove 111 and is inclined from the second side plate 117 toward the opening 1111. When the edge of the laminate 200 enters the mounting groove 111, the first extension 1151 can be pressed against the laminate 200, making it difficult for the laminate 200 to separate from the mounting groove 111, thereby improving the fixing reliability between the laminate 200 and the photovoltaic frame 100. For example, in another embodiment, only the second extension portion 1152 extends into the mounting groove 111, and the second extension portion 1152 is inclined from the second side panel 117 toward the opening 1111. When the edge side of the laminate 200 enters the mounting groove 111, the second extension portion 1152 can be pressed on the laminate 200, and the laminate 200 is not easy to detach from the mounting groove 111, thereby improving the fixation reliability between the laminate 200 and the photovoltaic frame 100. For example, in another embodiment, the first extension portion 1151 and the second extension portion 1152 both extend into the mounting groove 111, and the first extension portion 1151 is inclined from the second side plate 117 toward the opening 1111, and the second extension portion 1152 is inclined from the second side plate 117 toward the opening 1111. When the edge side of the laminate 200 enters the mounting groove 111, the first extension portion 1151 and the second extension portion 1152 are pressed onto the laminate 200 at the same time, and the laminate 200 is not easy to detach from the mounting groove 111, thereby improving the fixation reliability between the laminate 200 and the photovoltaic frame 100.

[0049] In the above-mentioned photovoltaic frame 100, when the edge side of the laminate 200 enters the installation groove 111, the first extension part 1151 and / or the second extension part 1152 are pressed on the laminate 200, and the first extension part 1151 and / or the second extension part 1152 apply pressure to the laminate 200, so that the laminate 200 is not easy to detach from the installation groove 111, thereby improving the fixing reliability between the laminate 200 and the photovoltaic frame 100.

[0050] Traditionally, the connector is connected to the frame by screwing. Due to the limited operating space of the accommodating cavity, the operation of the screwed connector on the frame is limited. Based on this, in one embodiment, refer to Figure 1 、 Figure 2 and Figure 4 As shown, the frame 110 is further provided with at least one connecting protrusion 119. The connecting protrusion 119 protrudes into the accommodating cavity 112 and is capable of cooperating with the connecting member 120. Exemplarily, the connecting member 120 has a groove (not shown) that cooperates with the connecting protrusion 119. When the connecting member 120 is at least partially accommodated in the accommodating cavity 112, the groove of the connecting member 120 and the connecting protrusion 119 form an interference fit, thereby achieving a stable connection between the frame 110 and the connecting member 120. Preferably, the connecting protrusion 119 is integrally formed with the frame 110 by stamping, casting, or the like, to simplify the molding process of providing the connecting protrusion 119 on the frame 110 and to improve the structural strength between the connecting protrusion 119 and the frame 110. The connecting protrusion 119 is preferably provided on the first side panel 116. Furthermore, there are a plurality of connecting protrusions 119 , and the plurality of connecting protrusions 119 are arranged at intervals to further enhance the stable connection between the frame 110 and the connecting member 120 .

[0051] See Figure 2 As shown, during the operation of the photovoltaic module 300, there is a potential difference between the photovoltaic frame 100 and the laminate 200, which causes the ions generated by the aging of the photovoltaic module 300 to float and gather on the surface of the laminate 200, thereby causing the potential induced attenuation effect of the photovoltaic module 300, affecting the working efficiency of the photovoltaic module 300. Therefore, it is necessary to ground the photovoltaic frame 100 to eliminate the potential induced attenuation effect of the photovoltaic module 300.

[0052] Based on this, in one embodiment, refer to Figure 2 and Figure 5As shown, frame 110 includes a main body 130 and a fin 140 extending outward from main body 130. Fin 140 is provided with a grounding hole 150 for connecting a grounding member (not shown). For example, the grounding member can be fastened to grounding hole 150 using a grounding screw, thereby grounding photovoltaic frame 100 and eliminating the potential induction effect of photovoltaic module 300. Furthermore, fin 140 extending outward from main body 130 simplifies the process of creating grounding hole 150, reducing the cost of creating grounding hole 150 in frame 110.

[0053] Further, see Figure 2 and Figure 5 As shown, there are multiple grounding holes 150, and the multiple grounding holes 150 are spaced apart on the flash edge 140. In this embodiment, at least two grounding holes 150 are opened on the frame 110. When multiple photovoltaic modules 300 are installed in a shingled manner on the installation surface, the two grounding holes 150 can realize electrical connection between two adjacent photovoltaic modules 300.

[0054] In another embodiment, see Figure 2 and Figure 6 As shown, the frame 110 is provided with an avoidance hole 160, and the connector 120 is provided with a grounding hole 150 for connecting to a grounding member. When the connector 120 is accommodated in the accommodating cavity 112, the grounding hole 150 is located within the avoidance hole 160. The grounding hole 150 is exposed through the avoidance hole 160, and the grounding member can be locked to the grounding hole 150 by a grounding screw to achieve grounding of the photovoltaic frame 100 and eliminate the potential induction effect of the photovoltaic module 300. For example, if a through hole is provided at the end position of the frame 110, when the connector 120 is accommodated in the accommodating cavity 112 and two adjacent photovoltaic frames 100 are connected, the through holes at the end positions of the two adjacent frames 110 are combined to form the avoidance hole 160.

[0055] Also, see Figure 1-Figure 4 As shown, the present application further provides a photovoltaic assembly 300, which includes a laminate 200 and a photovoltaic frame 100 as described in any of the above technical solutions, wherein the laminate 200 is mounted on the photovoltaic frame 100. Specifically, the photovoltaic frame 100 is wrapped around the edge of the laminate 200. For example, the frame of the photovoltaic frame 100 is clipped onto the photovoltaic frame 100, and then the laminate 200 is bonded and fixed to the photovoltaic frame 100 by an adhesive, thereby achieving the installation and fixation of the laminate 200 on the photovoltaic frame 100.

[0056] In the photovoltaic module 300 described above, the edge of the laminate 200 enters the mounting groove 111 through the opening 1111 and is bonded and fixed to the photovoltaic frame 100. The overflow groove 113 controls the overflow of the adhesive during the bonding process of the laminate 200. The accommodating cavity 112 is used to accommodate the connecting member 120, and the two adjacent photovoltaic frames 100 are fixedly connected by the connecting member 120. Because the accommodating cavity 112 is located on the side of the mounting groove 111 away from the opening 1111, when the laminate 200 needs to be fixed to the mounting plane through the photovoltaic frame 100, the accommodating cavity 112 will not interfere with the bonding and locking between the backlight surface of the laminate 200 and the mounting plane. The distance between the backlight surface of the laminate 200 and the mounting plane is small, which reduces the amount of adhesive filling between the backlight surface of the laminate 200 and the mounting plane, simplifying the bonding and locking operation between the laminate 200 and the mounting plane.

[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
