[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0026] The following is for reference. Figure 1 and Figure 2 The frame 100 of the photovoltaic module according to an embodiment of the present utility model is described.

[0027] like Figure 1 and Figure 2 As shown, the frame 100 of the photovoltaic module according to the first aspect embodiment of the present invention includes: a frame body 10 and a reinforcing member 20. The frame body 10 is an insulating composite material frame, and the reinforcing member 20 is embedded in the wall of the frame body 10 so that the wall of the frame body 10 wraps the reinforcing member 20.

[0028] It is understandable that the frame body 10 and the reinforcing member 20 constitute the frame 100 of the photovoltaic module. The reinforcing member 20 is embedded in the wall of the frame body 10. This arrangement can protect the reinforcing member 20 from the frame body 10 and strengthen the interior of the frame body 10 from the reinforcing member 20. This can improve the strength of the frame 100 of the photovoltaic module and prevent the mounting holes on the frame body 10 from being broken by forces in multiple directions when the bolts are installed on the photovoltaic module, thereby improving the reliability of the photovoltaic module.

[0029] The frame body 10 is an insulated composite material frame, while the reinforcing member 20 is a metal component. This arrangement facilitates the placement of the metal component within the composite material frame and also provides insulation between the frame body 10 and the reinforcing member 20. This ensures the performance of the photovoltaic module and increases the creepage distance, thereby enabling the photovoltaic module to achieve higher voltages. For example, the photovoltaic module can be increased to 2000V or 3000V.

[0030] For example, the frame body 10 is a composite material frame made of glass fiber and polymer material, with the polymer material being resin. The reinforcing member 20 is a metal reinforcing member, which is made of aluminum or steel. This arrangement can ensure the strength of the photovoltaic module frame 100 and also ensure the performance of the photovoltaic module, thereby improving the reliability of the photovoltaic module frame 100.

[0031] Therefore, the frame 100 of the photovoltaic module is made of an insulating composite material frame, and a reinforcing member 20 is embedded in the frame body 10. This arrangement allows the insulating composite material frame to wrap the reinforcing member 20, thereby preventing the mounting holes on the frame body 10 from being torn when installing bolts, and also preventing the reinforcing member 20 from being corroded by air, thus improving the performance and reliability of the frame 100 of the photovoltaic module.

[0032] Among them, such as Figure 1 As shown, the frame body 10 includes: a mounting part 11 and a fixing part 12. The mounting part 11 has a mounting groove for mounting the photovoltaic cell 30. The fixing part 12 is connected to the bottom of the mounting part 11 and is used to fix the photovoltaic bracket. The reinforcing member 20 is embedded in the wall of the fixing part 12.

[0033] It is understood that the mounting part 11 and the fixing part 12 constitute the frame body 10. The mounting part 11 forms a mounting groove, which can limit the photovoltaic cell 30, thereby facilitating the installation of the photovoltaic cell 30 on the frame 100 of the photovoltaic module. The fixing part 12 is connected to the mounting part 11 and is located at the bottom of the mounting part 11, thereby forming a frame structure with the fixing part 12 and the mounting part 11, which can improve the structural strength of the frame 100 of the photovoltaic module. The fixing part 12 is used to fix the photovoltaic bracket, thereby facilitating the installation of the photovoltaic cell 30 and the photovoltaic bracket on the frame 100 of the photovoltaic module, thus ensuring the performance of the photovoltaic module. The reinforcing member 20 is embedded in the wall of the fixing part 12. This arrangement can protect the reinforcing member 20 from the fixing part 12 and strengthen the interior of the fixing part 12, thereby improving the strength of the fixing part 12. It can also prevent the mounting holes on the frame body 10 from being broken by forces in multiple directions when the bolts are installed on the photovoltaic module, thereby improving the reliability of the photovoltaic module.

[0034] In addition, such as Figure 1 As shown, the fixing part 12 includes: a base plate 121, a first side plate 122 and a second side plate 123, the first side plate 122 and the second side plate 123 are respectively connected between the mounting part 11 and the base plate 121 and are spaced apart; wherein, the reinforcing member 20 is embedded in at least one of the base plate 121, the first side plate 122 and the second side plate 123.

[0035] In other words, the base plate 121, the first side plate 122, and the second side plate 123 constitute the main structure of the fixing part 12. The first side plate 122 and the second side plate 123 are arranged in parallel and spaced apart. One end of the first side plate 122 and the second side plate 123 is connected to the mounting part 11, and two ends of the first side plate 122 and the second side plate 123 are connected to the base plate 121. This allows a frame structure to be formed between the first side plate 122, the second side plate 123, the mounting part 11, and the base plate 121, thereby improving the structural strength of the photovoltaic module frame 100. The reinforcing member 20 is embedded in the base plate. The base plate 121, the first side plate 122, and the second side plate 123 are arranged in such a way that the base plate 121, the first side plate 122, and the second side plate 123 can protect the reinforcing member 20, and the reinforcing member 20 can strengthen the interior of the base plate 121, the first side plate 122, and the second side plate 123. This can improve the strength of the base plate 121, the first side plate 122, and the second side plate 123, and can also prevent the mounting holes on the frame body 10 from being broken by forces in multiple directions when the bolts are installed on the photovoltaic module, thereby improving the reliability of the photovoltaic module.

[0036] In addition, such as Figure 1 and Figure 2As shown, the reinforcing member 20 includes: a reinforcing base plate 21, a first reinforcing side plate 22, and a second reinforcing side plate 23. The reinforcing base plate 21 is embedded in the base plate 121, the first reinforcing side plate 22 is embedded in the first side plate 122, and the second reinforcing side plate 23 is embedded in the second side plate 123. The first reinforcing side plate 22 and the second reinforcing side plate 23 are respectively connected to the reinforcing base plate 21.

[0037] It is understood that the reinforcing base plate 21, the first reinforcing side plate 22, and the second reinforcing side plate 23 constitute the main structure of the reinforcing member 20. The reinforcing base plate 21 is embedded in the wall of the base plate 121. This arrangement allows the base plate 121 to protect the reinforcing base plate 21 and also to strengthen the base plate 121, thereby increasing the strength of the base plate 121. The first reinforcing side plate 22 is embedded in the wall of the first side plate 122. This arrangement allows the first side plate 122 to protect the first reinforcing side plate 22 and also to strengthen the first side plate 122, thereby increasing the strength of the first side plate 122. The second reinforcing side plate... The first reinforcing side plate 22 and the second reinforcing side plate 23 are embedded in the wall of the second side plate 123. This arrangement allows the second side plate 123 to protect the second reinforcing side plate 23 and also to strengthen the second side plate 123, thereby improving the strength of the second side plate 123. Moreover, the first reinforcing side plate 22 and the second reinforcing side plate 23 are respectively connected to the reinforcing base plate 21. This arrangement facilitates the joint support of the mounting part 11 by the reinforcing base plate 21, the first reinforcing side plate 22 and the second reinforcing side plate 23, and also increases the metallic conductivity of the reinforcing base plate 21, the first reinforcing side plate 22 and the second reinforcing side plate 23, thereby ensuring the performance and reliability of the photovoltaic module frame 100.

[0038] Optionally, such as Figure 1 As shown, the width of the base plate 121 is d1, and the width of the reinforcing base plate 21 is d2. d1 and d2 satisfy the relationship: 0.8d1≤d2<d1; the width of the first side plate 122 is d3, and the width of the first reinforcing side plate 22 is d4. d3 and d4 satisfy the relationship: 0.8d3≤d4<1.1d3; the width of the second side plate 123 is d5, and the width of the second reinforcing side plate 23 is d6. d5 and d6 satisfy the relationship: 0.8d5≤d6<1.1d5.

[0039] In other words, the widths of the base plate 121 and the reinforcing base plate 21 must be within a reasonable range. If the width of the reinforcing base plate 21 is less than eight-tenths of the width of the base plate 121, it will prevent the reinforcing base plate 21 from being embedded into the inner wall of the base plate 121 to the maximum extent, and it will also prevent the reinforcing base plate 21 from strengthening the base plate 121 to the maximum extent. If the width of the reinforcing base plate 21 is greater than the width of the base plate 121, it will cause the reinforcing base plate 21 to protrude from the base plate 121, which will lead to the reinforcing base plate 21 being subject to air corrosion and will also affect the performance of the photovoltaic module. If the widths of the base plate 121 and the reinforcing base plate 21 are within a reasonable range, it can ensure that the reinforcing base plate 21 strengthens the base plate 121, thereby ensuring that the forces on the base plate 121 in both directions are within the bearing range, thus improving the strength and reliability of the base plate 121.

[0040] The widths of the first side plate 122 and the first reinforcing side plate 22 must be within a reasonable range. If the width of the first reinforcing side plate 22 is less than eight-tenths of the width of the first side plate 122, it will prevent the first reinforcing side plate 22 from being embedded into the inner wall of the first side plate 122 to the maximum extent, and it will also prevent the first reinforcing side plate 22 from strengthening the first side plate 122 to the maximum extent. If the width of the first reinforcing side plate 22 is greater than 1.1 times the width of the first side plate 122, it will cause the first reinforcing side plate 22 to protrude from the first side plate 122, which will lead to electrical connection between the first reinforcing side plate 22 and the photovoltaic module, and thus cause a short circuit in the photovoltaic module. If the widths of the first side plate 122 and the first reinforcing side plate 22 are within a reasonable range, it can ensure that the first reinforcing side plate 22 strengthens the first side plate 122, thereby ensuring that the force on the first side plate 122 in both directions is within the bearing range, thereby improving the strength and reliability of the first side plate 122.

[0041] The width of the second side plate 123 and the width of the second reinforcing side plate 23 must be within a reasonable range. If the width of the second reinforcing side plate 23 is less than eight-tenths of the width of the second side plate 123, the second reinforcing side plate 23 will not be able to be embedded into the inner wall of the second side plate 123 to the maximum extent, and the second reinforcing side plate 23 will not be able to strengthen the second side plate 123 to the maximum extent. If the width of the second reinforcing side plate 23 is greater than 1.1 times the width of the second side plate 123, the second reinforcing side plate 23 will protrude from the second side plate 123, which will cause the second reinforcing side plate 23 to be electrically connected to the photovoltaic module, and thus cause the photovoltaic module to short circuit. If the width of the second side plate 123 and the width of the second reinforcing side plate 23 are within a reasonable range, it can be ensured that the second reinforcing side plate 23 strengthens the second side plate 123, thereby ensuring that the force on the second side plate 123 in both directions is within the bearing range, thereby improving the strength and reliability of the second side plate 123.

[0042] In addition, such as Figure 1 As shown, the mounting part 11 includes a top plate 111, a middle plate 112 and a third side plate 113. The middle plate 112 is connected to the first side plate 122 and the second side plate 123 respectively. The third side plate 113 is connected between the top plate 111 and the middle plate 112. The top plate 111, the third side plate 113 and the middle plate 112 together form a mounting groove. The third side plate 113 is connected to the top of the first side plate 122.

[0043] It is understood that the top plate 111, the middle plate 112, and the third side plate 113 constitute the main structure of the mounting part 11. One end of the middle plate 112 is connected to the first side plate 122, and the other end is connected to the second side plate 123. This allows the middle plate 112, the first side plate 122, the second side plate 123, and the bottom plate 121 to form a frame structure, thereby improving the structural strength of the frame 100 of the photovoltaic module. The third side plate 113 is located between the top plate 111 and the middle plate 112, and the top of the third side plate 113 is connected to the first side plate 122. This allows the top plate 111, the middle plate 112, and the third side plate 113 to form a "C" shape, thus forming a mounting groove. The mounting groove can limit the position of the photovoltaic cell 30, thereby facilitating the installation of the photovoltaic cell 30 on the frame 100 of the photovoltaic module.

[0044] In particular, Figure 1 As shown, the top plate 111 has an overflow groove 114, the opening of which is connected to the mounting groove. This arrangement allows excess adhesive on the photovoltaic cell 30 to flow into the overflow groove 114 after it is mounted on the frame 100 of the photovoltaic module via the mounting groove. This design ensures that the adhesive does not flow onto the frame 100 of the photovoltaic module, thus guaranteeing the performance of the frame 100 of the photovoltaic module.

[0045] In addition, such as Figure 1 As shown, the middle plate 112, the first side plate 122, the second side plate 123 and the bottom plate 121 together form a cavity 115, which is used to install corner brackets; wherein, the side of the middle plate 112 facing the cavity 115 and / or the side of the bottom plate 121 facing the cavity 115 are provided with protruding ribs 116. In other words, the middle plate 112, the first side plate 122, the second side plate 123, and the bottom plate 121 form a frame structure, which can improve the structural strength of the frame 100 of the photovoltaic module. Moreover, a cavity 115 is formed between the middle plate 112, the first side plate 122, the second side plate 123, and the bottom plate 121, which facilitates the installation of corner brackets in the cavity 115. A rib 116 is provided on the side of the middle plate 112 facing the cavity 115, and a rib 116 is also provided on the side of the bottom plate 121 facing the cavity 115. This arrangement can improve the structural strength of the cavity 115, thereby ensuring the stability of the corner brackets installed on the frame 100 of the photovoltaic module.

[0046] A photovoltaic module according to a second aspect embodiment of the present invention includes: a frame 100 of the photovoltaic module described in the above embodiment. The main body 10 of the frame 100 is an insulating composite material frame, and a reinforcing member 20 is embedded within the main body 10. This arrangement allows the insulating composite material frame to enclose the reinforcing member 20, thereby preventing the mounting holes on the main body 10 from being torn during bolt installation and preventing the reinforcing member 20 from being corroded by air, thus improving the performance and reliability of the frame 100 of the photovoltaic module.
