[0058] Example 1

[0059] 2 to 4 , this embodiment provides a photovoltaic assembly, including a solar panel 100, a keel 400, a pressing block 300 and a frame 200. The frame 200 is formed of a longer metal profile. The solar panel 100 is fixedly mounted on the frame 200. The keel 400 is fixed to the roof. The pressing block 300 is detachably connected to the frame 200 to limit and fix the frame 200. The pressing block 300 is fixed to the keel 400 via a connector 500.

[0060] As shown in Figure 1 , in the prior art, the two stoppers 31' of a pressure block 3' respectively abut against the upper surface of the frame 2' to secure the photovoltaic module in place. Externally, the pressure block 3' protrudes from the upper surface of the photovoltaic module, leaving it completely exposed. This design directly impacts the aesthetics and smoothness of the photovoltaic module.

[0061] In order to solve the above problems, as shown in Figures 2 and 4, in this embodiment, the frame 200 includes a first support plate 210, a second support plate 220, a first connecting plate 230 and a second connecting plate 240, and the second support plate 220 is spaced apart from the first support plate 210; the first connecting plate 230 is used to connect the first support plate 210 and the second support plate 220, and the second connecting plate 240 is spaced apart from the first connecting plate 230. The second connecting plate 240 connects the first support plate 210 and the second support plate 220. The first support plate 210, the second support plate 220, the first connecting plate 230 and the second connecting plate 240 jointly define a connecting groove 250. A notch 241 is provided on the second connecting plate 240 so that the connecting groove 250 is connected to the side of the second connecting plate 240 away from the first connecting plate 230. The pressing block 300 can be partially embedded in the connecting groove 250 through the notch 241 to be detachably connected to the connecting groove 250.

[0062] When the frame 200 is installed, the pressing block 300 used to cooperate with the frame 200 is partially embedded in the connecting groove 250 through the notch 241. At the same time, part of the pressing block 300 is supported on the groove wall. The connecting groove 250 can partially cover the structure of the pressing block 300, preventing the pressing block 300 from being fully exposed and invisible from the outside, thereby improving the smoothness and aesthetics of the photovoltaic module. In this embodiment, the cross-sectional shape of the connecting groove 250 can be rectangular, T-shaped, or other shapes, as long as at least a portion of the pressing block 300 can be embedded in the connecting groove 250 and tightly abut against the side walls of the connecting groove 250. No specific limitation is made here.

[0063] Specifically, as shown in Figure 2, the first support plate 210 and the second support plate 220 are arranged in parallel, and the first connecting plate 230 and the second connecting plate 240 are arranged in parallel. The cross-section of the first connecting plate 230 is perpendicular to the cross-sections of the first support plate 210 and the second support plate 220. Similarly, the cross-section of the second connecting plate 240 is perpendicular to the cross-sections of the first support plate 210 and the second support plate 220, and is connected to the ends of the first support plate 210 and the second support plate 220. The entire frame 200 has a simple structure and is easy to manufacture.

[0064] Furthermore, as shown in Figures 2 and 3, the frame 200 also includes a third connecting plate 260, which extends from the first support plate 210 in a direction away from the second support plate 220. The third connecting plate 260 and the first support plate 210 define a mounting groove 270, so that the mounting groove 270 has both a side opening 272 and an upper opening 271. The solar panel 100 can be accommodated and fixed in the mounting groove 270. In the prior art, a configuration commonly used is to vertically connect a top plate to the top of the third connecting plate 260 to cover the upper opening 271. In other words, in the prior art, the mounting groove 270 has only a side opening 272 for the solar panel 100 to be inserted. As shown in Figure 3, during actual installation, due to the slanted roof, the solar panel 100 and frame 200 are also tilted. This can cause some accumulated dust or water to flow from the upper surface of the solar panel 100 into the top plate of the frame 200 in the direction of the arrow, and accumulate between the top plate and the solar panel 100, preventing it from being drained away. This ultimately affects the normal use of the photovoltaic module. In this embodiment, by removing the top plate, the upper surface of the solar panel 100 is unobstructed. This allows some accumulated dust or water to flow from the upper surface of the solar panel 100 in the direction of the arrow and eventually out of the frame 200, thereby achieving the desired drainage and dust prevention effects.

[0065] 2 and 3 , a second chamfer 261 is formed on the side of the third connecting plate 260 away from the first support plate 210. The second chamfer 261 prevents the corners of the frame 200 from being too sharp, thus preventing the operator from being scratched during operation.

[0066] In some embodiments, as shown in Figures 2 and 3, the frame 200 further includes a fourth connecting plate 280, which is located between the first connecting plate 230 and the second connecting plate 240. The fourth connecting plate 280 is an L-shaped structure, with one end connected to the first support plate 210 and the other end connected to the second connecting plate 240. In this embodiment, the connecting groove 250 is specifically defined by the first support plate 210, the second connecting plate 240, and the fourth connecting plate 280. By adding the fourth connecting plate 280, the structural strength of the entire frame 200 can be improved, the stability and reliability of the photovoltaic module can be improved, and the long-term stable operation of the photovoltaic module outdoors can be ensured.

[0067] It should be noted that, as shown in FIG4 , the frame 200 and the corresponding solar panel 100 accommodated and installed therein constitute a photovoltaic panel. For example, a frame 200 is provided at each end of each solar panel 100, i.e., one solar panel 100 and two frames 200 constitute a photovoltaic panel. In this embodiment, the photovoltaic assembly includes at least two photovoltaic panels, which are arranged side by side. The connection grooves 250 of two adjacent photovoltaic panels are connected to the same pressing block 300. This allows the two photovoltaic panels to be fixedly installed simultaneously using a single pressing block 300, saving materials and costs, simplifying the installation process, shortening installation time, and making the adjacent photovoltaic panels compact and reducing the floor space.

[0068] It should be noted that there is a gap between two adjacent photovoltaic panels and above the pressing block 300. To completely conceal the pressing block 300, this gap can be filled with a glue layer 390 (as shown in FIG7 ). Preferably, the surface color of the glue layer 390 can be painted to a color similar to that of the solar panel 100, thereby completely obscuring the pressing block 300 and making it completely invisible from the outside. Preferably, the upper surface of the glue layer 390 can be flush with the upper surface of the photovoltaic panel, thereby further improving the flatness, consistency, and aesthetics of the photovoltaic module.

[0069] Specifically, as shown in Figures 4 and 5, in this embodiment, the pressure block 300 includes a base 320 and a pressure block body 310. The base 320 is fixed to the keel 400 via a connector 500. The connector 500 is a bolt or screw that passes through the base 320 and is threadedly connected to the keel 400, thereby fixing the base 320 to the keel 400. One end of the pressure block body 310 is rotatably mounted on the base 320, and the other end of the pressure block body 310 is detachably connected to the connecting groove 250. In other words, by rotating the pressure block body 310, the end of the pressure block body 310 can be snapped into the connecting groove 250, thereby fixing the frame 200, which is convenient for operation. In this embodiment, the base 320 and the pressure block body 310 are manufactured separately and can be assembled when in use.

[0070] Specifically, the pressure block 300 includes two pressure block bodies 310, which are spaced apart and rotatably mounted on a base 320. An elastic member 330 is disposed between the two pressure block bodies 310, with both ends of the elastic member 330 pressing against the corresponding pressure block body 310. Preferably, in this embodiment, the elastic member 330 is a spring, comprising two elastic arms 331 disposed at an acute angle, each elastic arm 331 abutting against a corresponding pressure block body 310. When the pressure block body 310 is engaged with the corresponding connection slot 250, each elastic arm 331 presses against the corresponding pressure block body 310. The elastic force of the elastic arms 331 restricts the rotation of the pressure block body 310, thereby stably engaging the pressure block body 310 in the connection slot 50 and preventing the pressure block body 310 from dislodging from the connection slot 250. In other embodiments, the elastic member 330 may also be a spring.

[0071] Specifically, as shown in FIG4 , each pressure block body 310 includes a first limiting portion 311, a first adapter portion 312, and a rotating shaft portion 313. The first adapter portion 312 is connected between the first limiting portion 311 and the rotating shaft portion 313. The first limiting portion 311 extends away from the elastic member 330. The two ends of the elastic member 330 abut against the two first adapter portions 312. The first limiting portion 311 is configured to partially fit into the connecting groove 250 through the notch 241. The rotating shaft portion 313 is rotatably mounted on the base 320. In this embodiment, the pressure block body 310 is configured in a snap-fit ​​manner. The first limiting portion 311 can be engaged with or removed from the connecting groove 250 by rotating, which is convenient for operation.

[0072] To enable the rotation of the shaft portion 313, a shaft hole 321 is defined in the base 320. The shaft portion 313 can rotate within the shaft hole 321. The shaft hole 321 extends along the length of the base 320 and penetrates at least one end of the base 320. A clearance opening 322 is formed at the top of the shaft hole 321 to clear the first adapter portion 312. When installing the pressure block body 310, the shaft portion 313 can be simply slid into the shaft hole 321 from one end. After the pressure block body 310 is installed, the shaft hole 321 can be sealed at both ends with a nut or other structure to prevent the pressure block body 310 from falling off.

[0073] Preferably, as shown in Figures 4 and 5 , the first stopper 311 has a chamfered surface 3111 on the side facing the frame 200. The chamfered surface 3111 is inclined from bottom to top in a direction away from the frame 200. A first chamfer 290 (as shown in Figure 2 ) is provided between the second support plate 220 and the second connecting plate 240. The chamfered surface 3111 can slidably engage with the first chamfer 290. This arrangement is simple in structure and easy to operate. Simply by engaging the chamfered surface 3111 with the first chamfer 290, the sliding movement between the frame 200 and the first stopper 311 can be converted into rotation of the pressing block body 310, thereby facilitating installation of the frame 200.

[0074] When the first stop 311 is aligned with the opening of the connecting groove 250 on the frame 200, the elastic arm 331 rebounds, so that the first stop 311 is engaged with the connecting groove 250. At this time, the installation of a photovoltaic panel is completed. The elastic force of the elastic arm 331 can make the first stop 311 stably engaged with the connecting groove 250 to limit and fix the frame 200. The installation process of another adjacent photovoltaic panel is similar. During disassembly, it is only necessary to press the elastic arm 331 inwards so that the elastic arm 331 drives the pressing block body 310 to rotate inwards so that the first limiting portion 311 is pulled out of the connection groove 250. At this time, the frame 200 and the solar panel 100 can be lifted by hand to complete the disassembly, which is relatively convenient for assembly and disassembly and maintenance. It should be noted that when the pressing block 300 is applied to the middle position of the photovoltaic module, each pressing block 300 corresponds to the frame 200 of two adjacent photovoltaic panels, and when the pressing block 300 is applied to the end of the photovoltaic module, the pressing block 300 has only one pressing block body 310 that cooperates with the frame 200 of one photovoltaic panel, and the other pressing block body 310 is idle, and the idle pressing block body 310 can limit the elastic member 330. The above installation process is a quick installation process, that is, each photovoltaic panel can be installed separately on the roof, and the operation is relatively flexible and fast.

[0075] Preferably, as shown in FIG5 , the escape opening 322 at the top of the shaft hole 321 has two sidewalls, wherein the sidewall facing away from the elastic member 330 is a plane, and the plane is arranged in the vertical direction. When the pressure block body 310 is inserted into the connecting groove 250 or the frame 200 is not installed, the sidewall of the first adapter portion 312 can abut against the plane, thereby forming a limit and preventing rotation. At this time, the first adapter portion 312 of the pressure block body 310 is in a vertically arranged state. The sidewall of the escape opening 322 on the side near the elastic member 330 is arranged as an arcuate surface or an inclined surface, which is inclined from bottom to top toward the side near the elastic member 330. When the pressure block body 310 rotates inward, this arrangement can leave sufficient rotation space for the first adapter portion 312 to prevent interference.

[0076] Example 2

[0077] The photovoltaic assembly provided in this embodiment has substantially the same structure as that provided in the first embodiment, and the similarities are not repeated here. The difference mainly lies in the specific structure of the pressing block 300 .

[0078] Specifically, as shown in FIG6 , in this embodiment, the pressing block 300 is an integrally formed structure. The pressing block 300 includes a second limiting portion 340 and a connecting portion 350 connected to each other. The second limiting portion 340 extends in a direction away from the connecting portion 350. The second limiting portion 340 can pass through the notch 241 and partially embed into the connecting groove 250. The connecting portion 350 is connected to the keel 400 via a connecting member 500. The connecting member 500 is a bolt or a screw. Due to the locking effect of the connecting member 500, after the second limiting portion 340 is inserted into the connecting groove 250, its bottom surface abuts against the groove wall of the connecting groove 250, thereby clamping and fixing the frame 200. At the same time, the bottom of the frame 200 abuts against the upper surface of the keel 400, thereby forming a stable fixing effect on the frame 200. In the photovoltaic module provided by this embodiment, the connecting groove 250 can also partially shield the structure of the pressing block 300, preventing the pressing block 300 from being fully exposed and invisible from the outside, thereby improving the flatness and aesthetics of the photovoltaic module. In this embodiment, the cross-sectional shape of the connecting groove 250 can be rectangular, T-shaped, or other shapes, as long as at least a portion of the pressing block 300 can be snapped into the connecting groove 250 and abutted against the sidewalls of the connecting groove 250. No specific limitation is imposed herein.

[0079] Specifically, as shown in Figure 6, the pressing block 300 includes two second stoppers 340, which are respectively connected to the ends of the connecting portion 350 and extend in directions away from each other. Each second stopper 340 is capable of snapping into the connecting groove 250 of the corresponding side frame 200. In other words, through a single connector 500 and the two second stoppers 340 of a pressing block 300, two adjacent photovoltaic panels can be simultaneously secured together, saving materials and costs, simplifying the installation process, shortening installation time, and making the adjacent photovoltaic panels compact and reducing floor space.

[0080] Example 3

[0081] The photovoltaic assembly provided in this embodiment has substantially the same structure as that provided in the first and second embodiments, and the similarities are not repeated here. The difference mainly lies in the specific structure of the pressing block 300 .

[0082] Specifically, as shown in FIG7 , in this embodiment, the pressing block 300 is an integrally formed structure and is made of a metal profile. The pressing block 300 includes a third limiting portion 360, a second transition portion 370 and a fixing portion 380. The second transition portion 370 is vertically connected between the third limiting portion 360 and the fixing portion 380. The third limiting portion 360 can be inserted into the connecting groove 250. The second support plate (220) is attached to the upper surface of the fixing portion 380. The fixing portion 380 is connected to the second support plate 220 through a connecting member 500, thereby fixing the frame 200 and the pressing block 300 as a whole to ensure the stability of the photovoltaic module. The connecting member 500 can be a bolt or a nut. In the photovoltaic module provided in this embodiment, the connecting groove 250 can also shield the pressing block 300 to prevent the pressing block 300 from being exposed, and the pressing block 300 cannot be seen from the appearance, thereby improving the flatness and aesthetics of the photovoltaic module.

[0083] Specifically, as shown in Figure 7, the third limiting portion 360 is a T-shaped structure, and the connecting groove 250 is a T-shaped groove that is compatible with the third limiting portion 360. The connecting groove 250 extends along the length of the frame 200 and passes through at least one end of the frame 200. The third limiting portion 360 can slide into the connecting groove 250 from one end and be locked in the connecting groove 250. By adopting this arrangement, the third limiting portion 360 can be prevented from being separated from the connecting groove 250, ensuring the reliability of the fit between the pressure block 300 and the frame 200, thereby ensuring the stability of the connecting assembly 300. When assembling the frame 200 and the pressure block 300, the third limiting portion 360 can be slid into the connecting groove 250 from one end. After sliding to the appropriate position, the fixing portion 380 is fastened to the second support plate 220 via the connector 500, which is convenient to operate. In other embodiments, the third limiting portion 360 and the connecting groove 250 can also be constructed as an L-shaped structure, a trapezoidal structure or a structure of other shapes, as long as it can ensure that the third limiting portion 360 can be locked in the connecting groove 250, and no specific limitation is made here.

[0084] Specifically, the pressing block 300 includes two third limiting portions 360, which are respectively connected to opposite sides of the second adapter portion 370. Each third limiting portion 360 can be inserted into the connection groove 250 of the frame 200 on the corresponding side. In other words, the end of a second adapter portion 370 is simultaneously connected to two third limiting portions 360 arranged in opposite directions. The fixing portion 380 extends horizontally and is fastened to both supporting edges 250 via the connector 500 to ensure the stability of the photovoltaic module. By providing a single pressing block 300, two adjacent photovoltaic panels can be simultaneously fixed, saving materials and costs, facilitating installation operations, shortening installation time, and making the structures of the two adjacent photovoltaic panels compact and reducing floor space.

[0085] It should be noted that when the pressing block 300 is applied to the end of the photovoltaic module, the pressing block 300 only has a third limiting portion 360 that cooperates with the frame 200 of a photovoltaic panel, and the bottom end of the fixing portion 380 needs to be fixed to the keel 400 through the connecting piece 500. When the pressing block 300 is applied to the middle position of the photovoltaic module, each pressing block 300 corresponds to the frame 200 of two adjacent photovoltaic panels, and the keel 400 does not need to be set at the bottom of the fixing portion 380, that is, the fixing portion 380 is suspended in the air, and the entire photovoltaic module only needs to be supported by the keel 400 located at the end. The photovoltaic module provided in this embodiment first assembles the small photovoltaic panels into a large panel assembly on the ground through the pressing block 300, and then fixes the large panel assembly as a whole on the roof, reducing the installation workload on the roof.

[0086] Optionally, as shown in FIG7 , there is a gap between the two photovoltaic panels and above the third limiting portion 360, and the gap is smaller than that of the solutions of the first and second embodiments. In order to completely hide the pressing block 300, the gap can be filled with a glue layer 390. Preferably, the surface color of the glue layer 390 can be painted to a color similar to that of the solar panel 100, so that the pressing block 300 is completely covered and the pressing block 300 is completely invisible from the outside. Preferably, the upper surface of the glue layer 390 can be flush with the upper surface of the photovoltaic panel, thereby further improving the flatness, consistency and aesthetics of the photovoltaic module.

[0087] To sum up, the frame 200 structures provided in the above three embodiments can be exactly the same, so that the frame 200 can be adapted to different forms of pressing blocks 300, and can be suitable for both quick installation and traditional assembly, thus being suitable for different installation scenarios, being more flexible to use, and having better versatility.

[0088] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
