[0048] Referring to FIG. 1 , FIG. 1 shows a cross-sectional schematic diagram of a first photovoltaic frame 10 in an embodiment of the present application. The photovoltaic frame 10 provided in an embodiment of the present application includes a frame 100, a limiting member 200 and a snap-in member 300, wherein the frame 100 is used to install the photovoltaic laminate 20. In a specific setting, the interior of the frame 100 has a first cavity, and the first cavity is used to install the photovoltaic angle code; the limiting member 200 includes a first cantilever 210 and a second cantilever 220, and the first cantilever 210 and the second cantilever 220 are spaced apart and arranged on a mounting wall 110 in the frame 100. In a specific setting, the first cantilever 210 and the second cantilever 220 are arranged opposite to each other, and the first cantilever 210, the second cantilever 220 and the mounting wall 110 form a limiting space 230; the snap-in member 300 includes a docking frame 310 and an extension plate 320, the docking frame 310 is detachably arranged in the limiting space 230, and the extension plate 320 is fixed to the docking frame 310 and is used to install connecting fasteners.

[0049] The photovoltaic frame 10 is provided with a docking frame 310 that is detachably disposed in the limiting space 230 in the frame 100, and the extension plate 320 connected to the docking frame 310 is used to install the connecting fasteners, thereby realizing the split connection between the extension plate 320 and the frame 100. At this time, the extension plate 320 does not need to have a bearing function, and the extension plate 320 can be designed to be a small area as required to provide an installation point for the connecting fasteners. Compared with the extension wall in the prior art, the area of ​​the back of the photovoltaic laminate 20 is greatly reduced, and the back of the photovoltaic laminate 20 can absorb more solar energy per unit time, which can improve the power generation efficiency of the photovoltaic laminate 20.

[0050] As shown in FIG. 2 and FIG. 3 , FIG. 2 is a cross-sectional schematic diagram of the frame body 100 and the limiting member 200 in FIG. 1 , and FIG. 3 is a cross-sectional schematic diagram of the clamping member 300 in FIG. 1 . In order to more conveniently realize that the docking frame 310 is detachably arranged in the limiting space 230 , in an optional embodiment, the first cantilever 210 includes a first docking plate 211 and a first limiting plate 212 connected to the first docking plate 211 at a preset angle, the first docking plate 211 is arranged on the mounting wall 110, and a first limiting groove 231 is formed between the first docking plate 211 and the first limiting plate 212. In the specific setting, the first docking plate 211 and the first limiting plate 212 are preferably connected at 90°, but are not limited to the above 90° connection.

[0051] The second cantilever 220 includes a second docking plate 221 and a second limiting plate 222 connected to the second docking plate 221 at a preset angle. The second docking plate 221 is arranged on the mounting wall 110. A second limiting groove 232 is formed between the second docking plate 221 and the second limiting plate 222. In specific settings, the second docking plate 221 and the second docking plate 221 can be connected at 90°, but are not limited to the above 90° connection. The second limiting plate 222 is arranged opposite to the first limiting plate 212. In specific settings, the second limiting plate 222 and the first limiting plate 212 are parallel and both are also parallel to the mounting wall 110. Through the above settings, the second limiting plate 222, the second docking plate 221, the mounting wall 110, the first docking plate 211 and the first limiting plate 212 form a limiting space 230 having a first limiting groove 231 and a second limiting groove 232.

[0052] The docking frame 310 has a mounting plate 311 and a first limiting protrusion 312 and a second limiting protrusion 313 disposed at both ends of the mounting plate 311. The first limiting protrusion 312 is matched with the first limiting groove 231, and the second limiting protrusion 313 is matched with the second limiting groove 232. Through the above arrangement, the first limiting groove 231 and the second limiting groove 232 in the limiting space 230 and the first limiting protrusion 312 and the second limiting protrusion 313 are engaged with each other relative to the ground, so that the docking frame 310 can be detachably disposed in the limiting space 230.

[0053] It should be noted that when the first limiting protrusion 312 and the second limiting protrusion 313 are respectively located in the first limiting groove 231 and the second limiting groove 232, the mounting plate 311 connecting the first limiting protrusion 312 and the second limiting protrusion 313 is located in the limiting space 230. In order to ensure that the height of the mounting plate 311 and the mounting wall 110 is adapted to prevent the mounting plate 311 from shaking in the limiting space 230, the mutually abutting surfaces of the mounting plate 311 and the mounting wall 110 need to be highly flat, but this will increase the difficulty of production. Based on this, in order to reduce the difficulty of production, specifically, a first reinforcing rib 314 abutting against the mounting wall 110 is provided on one side of the mounting plate 311 close to the mounting wall 110. When specifically set, the number of the first reinforcing rib 314 can be multiple, and the multiple first reinforcing ribs 314 are arranged at intervals from each other. Through the above arrangement, the contact between the mounting wall 110 and the mounting plate 311 with two large surfaces is changed to the contact between the mounting wall 110 and the reinforcing rib with a small surface area, thereby reducing the difficulty of production.

[0054] In order to prevent the docking frame 310 from being separated from the stopper 200, specifically, a first hook 315 is provided on the side of the second stopper protrusion 313 facing away from the mounting wall 110, and a second hook 223 is provided on the side of the second stopper plate 222 close to the mounting wall 110, and the first hook 315 and the second hook 223 are arranged in opposite directions and are engaged with each other. In the specific arrangement, the angle range of the reverse engagement of the first hook 315 and the second hook 223 can be selected to be 5°-15°, so as to ensure that the docking frame 310 is not easily loosened after being engaged with the stopper 200. In order to facilitate the first limiting protrusion 312 and the second limiting protrusion 313 to be clamped in the corresponding first limiting groove 231 and the second limiting groove 232, in the specific setting, the end of the first limiting plate 212 body used to form the first limiting groove 231 has a first inclined surface 2121 inclined upward, which is convenient for the introduction of the third inclined surface 3121 inclined upward at the top end of the first limiting protrusion 312, and the top of the second limiting plate 222 body used to form the second limiting groove 232 has a second inclined surface 2221 inclined downward, which is convenient for the introduction of the fourth inclined surface 3131 inclined downward at the bottom end of the second limiting protrusion 313.

[0055] Through the above arrangement, the first limiting protrusion 312 can be conveniently introduced into the first limiting groove 231 by utilizing the cooperation between the third inclined surface 3121 and the first inclined surface 2121, and the second limiting protrusion 313 can be conveniently introduced into the second limiting groove 232 by utilizing the cooperation between the fourth inclined surface 3131 and the second inclined surface 2221, thereby realizing the rapid clamping of the docking frame 310 and the limiting member 200, the clamping structure is simple and the clamping process is smooth and concise, the operation is simple, and time and labor are saved; and the docking frame 310 and the limiting member 200 are tightly fixed by the reverse locking of the first hook 315 and the second hook 223, so that the connection between the docking frame 310 and the limiting member 200 is stable and not easy to loosen. The above-mentioned whole installation process improves the working efficiency on the basis of ensuring stable connection, does not require complicated preparation work and waiting time, saves time cost, and reduces the working intensity of the operator.

[0056] It should be noted that the current photovoltaic frame has a fixed component covering the outside of the photovoltaic laminate. During long-term outdoor use, the connection edge between the photovoltaic laminate and the fixed component is prone to dust accumulation, thereby affecting the power generation of the photovoltaic laminate. Based on this, in order to further improve the power generation rate of the photovoltaic laminate 20 and reduce the dust accumulation at the connection edge between the photovoltaic laminate 20 and the fixed component, an optional embodiment is that the frame 100 also includes a bottom wall 120, an outer wall 130, a support plate 140 and a top plate 150, the two ends of the support plate 140 are respectively connected to the outer wall 130 and the mounting wall 110, the support plate 140 is used to carry the photovoltaic laminate 20, the outer wall 130 and the mounting wall 110 are spaced apart from the bottom wall 120, the outer wall 130 has a first end 131 higher than the support plate 140, the top plate 150 is connected to the first end 131 at a preset angle, and the highest point of the top plate 150 is not higher than the upper surface of the photovoltaic laminate 20. Through the above arrangement, there is no component in the photovoltaic frame 10 that blocks the upper surface of the photovoltaic laminate 20 , and dirt on the surface of the photovoltaic laminate 20 will not accumulate at the edge under the scouring of natural rainwater, thereby not affecting the power generation efficiency of the photovoltaic laminate 20 .

[0057] In order to strengthen the fixation of the photovoltaic frame 10 to the photovoltaic laminate 20, in the specific setting, the top plate 150, the first end 131 and the support plate 140 form a first glue storage space 160, and the first glue storage space 160 is used to set the sealing silicone 30, and the connection between the photovoltaic frame 10 and the photovoltaic laminate 20 is strengthened by the sealing silicone 30. The intuitive effect is shown in Figure 4, which is a cross-sectional schematic diagram of the frame 100 in Figure 1 carrying the photovoltaic laminate 20, but it should be noted that the first docking plate 211 and the second docking plate 221 in Figure 4 are both flush with the carrier plate, and in the process of placing the photovoltaic laminate 20 after adding the sealing silicone 30, the sealing silicone 30 will overflow.

[0058] To solve the above problems, an embodiment of the present application provides a cross-sectional schematic diagram of a second photovoltaic frame 10 as shown in FIG5, and a cross-sectional schematic diagram of a frame 100 in FIG5 carrying a photovoltaic laminate 20 as shown in FIG6. Specifically, a plurality of spaced first accommodating grooves 141 are provided on the support plate 140. In the specific setting, the number of the first accommodating grooves 141 is not limited, and can be set according to actual needs. The shape of the first accommodating groove 141 can be any geometric figure such as a rectangle, an ellipse, a polygon, etc. By setting the first accommodating groove 141, in the process of setting the photovoltaic laminate 20 in the sealing silicone 30, the sealing silicone 30 can flow into the first accommodating groove 141 to reduce the overflow of the sealing silicone 30, and the setting of the first accommodating groove 141 can also increase the amount of the sealing silicone 30, improve the adhesive strength of the sealing silicone 30, thereby strengthening the connection between the photovoltaic frame 10 and the photovoltaic laminate 20.

[0059] In order to further reduce the overflow of the sealing silicone 30 when it is squeezed, an embodiment of the present application provides a cross-sectional schematic diagram of a third photovoltaic frame 10 as shown in FIG7, and a cross-sectional schematic diagram of the frame 100 in FIG7 carrying the photovoltaic laminate 20 as shown in FIG8. More specifically, the first cantilever 210 is arranged at the top of the mounting wall 110 and is higher than the support plate 140, and the first cantilever 210 and the support plate 140 form a second adhesive space 213. In the specific setting, the first docking plate 211 in the first cantilever 210 is arranged at the top of the mounting wall 110, and the first docking plate 211 and the support plate 140 form a second adhesive space 213, so that the sealing silicone 30 can be well maintained on the support plate 140, preventing the sealing silicone 30 from overflowing after being compressed.

[0060] In order to improve the bearing capacity of the photovoltaic laminate 20, a plurality of spaced second reinforcing ribs 170 are arranged above the support plate 140. On the one hand, the arrangement of the second reinforcing ribs 170 is conducive to increasing the laying area of ​​the sealing silicone 30 so that the photovoltaic laminate 20 can be firmly adhered. On the other hand, it is conducive to enhancing the bearing capacity of the photovoltaic laminate 20 and improving the reliability of the installation. In the specific arrangement, the height of the second reinforcing ribs 170 can be selected to be flush with the height of the first docking plate 211 in the first cantilever 210.

[0061] As shown in FIG. 9 , FIG. 9 is a schematic diagram of the structure of the fourth photovoltaic frame 10 provided in an embodiment of the present application. The fourth photovoltaic frame 10 will also open a second receiving groove 152 on the inner side of the top plate 150. The shape of the second receiving groove 152 is not limited and can be any geometric shape. By setting the second receiving groove 152, when the photovoltaic laminate 20 is set in the sealing silicone 30, the second receiving groove 152 is used to cache the sealing silicone 30 and reduce the overflow of the sealing silicone 30. At the same time, it can also increase the amount of the sealing silicone 30 and improve the adhesive strength of the sealing silicone 30, thereby strengthening the connection between the photovoltaic frame 10 and the photovoltaic laminate 20.

[0062] In order to design the docking frame 310 more conveniently, specifically, the docking frame 310 also includes two connecting plates 316 and a positioning plate 317. The two connecting plates 316 are arranged at intervals on the mounting plate 311. The two ends of the positioning plate 317 are respectively connected to the two connecting plates 316. When specifically arranged, the mounting plate, the positioning plate 317 and the two connecting plates 316 are connected in a hollow rectangular structure to reduce the use of profiles and reduce the weight of the overall docking frame 310, which is convenient for users to use. The positioning plate 317 is also connected to the extension plate 320. The extension plate 320 is provided with a mounting through hole 321 for the connection fastener to fix the extension plate 320 at a preset position through the mounting through hole 321.

[0063] As shown in Figure 10, Figure 10 is a cross-sectional schematic diagram of the installation process of the limiting member 200 and the clamping member 300 in Figure 9. During the installation process of the clamping member 300, the third inclined surface 3121 of the first limiting protrusion is first guided and matched with the first inclined surface 2121 of the first limiting plate 212 to enter the first limiting groove 231, and then the clamping member 300 is rotated clockwise so that the second inclined surface 2221 of the second limiting protrusion is guided and matched with the second inclined surface 2221 of the second limiting plate 222 to enter the second limiting groove 232; and then the clamping member 300 is moved downward so that the first hook 315 and the second hook 223 are tightly reversely locked.

[0064] As shown in FIG. 11 , FIG. 11 is a cross-sectional schematic diagram of the photovoltaic frame 10 in FIG. 9 . In order to prevent the clamping member 300 from shaking in the limiting space 230, more specifically, a positioning groove 3171 is provided on the side of the positioning plate 317 away from the connecting plate 316, and the positioning fastener 400 passes through the docking frame 310 and is arranged on the installation wall 110 through the positioning groove 3171. The installation of the positioning fastener 400 is generally performed after the clamping member 300 is moved downward so that the first hook 315 and the second hook 223 are tightly reversely locked. After the clamping member 300 is adjusted to a suitable position, the clamping member 300 is locked to the frame 100 through the positioning fastener 400, thereby strengthening the connection between the clamping member 300 and the frame 100.

[0065] As shown in FIG12, FIG12 is a cross-sectional schematic diagram of the photovoltaic frame 10 in FIG9 used in conjunction with the pressing block 40. It should be noted that the top of the top plate 150 may also be provided with a mounting groove adapted to the pressing block 40. Through the above arrangement, when the photovoltaic frame 10 is used in conjunction with the pressing block 40, it is possible to avoid setting the clamping member 300 in the limited space 230, and the photovoltaic laminate 20 can be installed in a suitable position by installing the connecting fastener through the pressing block 40.

[0066] The present application also provides a photovoltaic assembly, which includes a photovoltaic laminate 20 and a photovoltaic frame 10 as described in any of the above embodiments, wherein the photovoltaic laminate 20 is installed on the photovoltaic frame 10. In a specific configuration, the photovoltaic frame 10 can be configured around the photovoltaic laminate 20.

[0067] The photovoltaic assembly is provided with a photovoltaic assembly including a photovoltaic laminate 20 and a photovoltaic frame 10 for installing the photovoltaic laminate 20. The docking frame 310 in the photovoltaic frame 10 is detachably arranged in the limited space 230 in the frame 100. The extension plate 320 connected to the docking frame 310 is used to install the connecting fasteners, thereby realizing the split connection between the extension plate 320 and the frame 100.
