[0038] Next, the frame of the photovoltaic module according to the first aspect embodiment of the present invention will be specifically described with reference to the accompanying drawings.

[0039] Figure 1 Installation schematic diagram of the frame of a photovoltaic module according to an embodiment of the present invention; Figure 2 Structural schematic diagram of the frame of a photovoltaic module according to an embodiment of the present invention; Figure 3 Structural schematic diagram of a pressing block according to an embodiment of the present invention;Figure 4 Structural schematic diagram of a crossbeam according to an embodiment of the present utility model; Figure 5 Partial structural schematic diagram of a photovoltaic module frame according to an embodiment of the present utility model; Figure 6 Partial structural schematic diagram of a photovoltaic module frame according to an embodiment of the present utility model.

[0040] Specifically, as Figures 1 to 6 shown, the photovoltaic module frame according to the first aspect embodiment of the present utility model, for a photovoltaic module, may include: a photovoltaic frame 1.

[0041] Wherein, a bottom plate 11 is provided at the bottom of the photovoltaic frame 1, the bottom plate 11 is used to connect the crossbeam 2, one side of the bottom plate 11 has an extension portion 111, a downward protruding limit protrusion 112 is provided on the bottom plate 11, and a connection hole 113 is provided on the bottom plate 11. A limit groove 21 corresponding to the limit protrusion 112 and an installation hole (not shown due to viewing angle) corresponding to the connection hole 113 are provided at the top of the crossbeam 2. The limit groove 21 runs through the crossbeam 2 in the width direction, and the limit protrusion 112 runs through the bottom plate 11 in a direction parallel to the limit groove 21.

[0042] That is to say, as Figures 1 to 6 shown, in the photovoltaic module frame according to the embodiment of the present utility model, during the installation process of the photovoltaic frame 1, first, the limit protrusion 112 of the photovoltaic frame 1 is matched with the limit groove 21 of the crossbeam 2, and then corresponding fixing parts, for example, fasteners 3, are successively passed through the connection hole 113 provided on the bottom plate 11 and the installation hole provided on the crossbeam 2, so as to stably install the photovoltaic frame on the crossbeam. By providing the extension portion 111 on one side of the bottom plate 11, the extension portion 111 can increase the contact area between the photovoltaic frame 1 and the crossbeam 2, disperse stress, and thus reduce the risk of tearing at the connection hole 113 on the bottom plate 11 due to excessive wind force. Through the cooperative action of the limit protrusion 112 and the limit groove 21, on the one hand, the positioning accuracy of the connection between the photovoltaic frame 1 and the crossbeam 2 is ensured, and on the other hand, the anti-load strength of the structure is improved, ensuring the stability of the structure. Thus, the photovoltaic module frame provided by the present utility model can effectively enhance the anti-tearing ability of the structure and the overall anti-load strength, ensuring the stability of the installation.

[0043] It should be noted that the crossbeam 2 can be a part of the photovoltaic module. That is to say, after the photovoltaic frame 1 and the crossbeam 2 are connected, they are integrally installed on the corresponding photovoltaic support; the crossbeam 2 can also be a part of the photovoltaic support, and the photovoltaic module is integrally installed on the crossbeam 2 of the photovoltaic support. That is to say, the crossbeam 2 can also not be a part of the photovoltaic module.

[0044] In some embodiments of the present utility model, as Figure 1As shown, the photovoltaic module frame further includes a fastener 3, which is used to sequentially pass through a connection hole 113 provided on the bottom plate 11 and a mounting hole provided on the cross beam 2 to connect the cross beam 2 to the photovoltaic frame 1. Thereby, the positioning accuracy of the connection between the photovoltaic frame 1 and the cross beam 2, as well as the load-bearing capacity and stability of the overall structure, are further improved.

[0045] The following combines Figures 1 to 6 , and briefly describes the installation process of the photovoltaic module frame: The operator first aligns the limit protrusion 112 on the bottom plate 11 of the photovoltaic frame 1 and slides it into the limit groove 21 on the cross beam 2 to ensure that the limit protrusion 112 is completely embedded in the limit groove 21, and the bottom plate 11 and the cross beam 2 are closely attached. After adjusting the photovoltaic frame 1 to a suitable position, then pass a fastener 3 (such as a bolt, etc.) through the connection hole 113 provided on the bottom plate 11 and the mounting hole provided on the cross beam 2 in sequence, so as to fix the photovoltaic frame 1 and the cross beam 2 together.

[0046] In some embodiments of the present invention, as Figure 2 and Figure 4 shown, the vertical cross-section of the limit protrusion 112 along its length direction is L-shaped, and the limit groove 21 has the same shape as the limit protrusion 112. That is to say, the L-shaped cross-section is perpendicular to the length direction of the limit protrusion 112. The L-shaped design can effectively limit the up and down movement of the limit protrusion 112 along the vertical direction or the movement along the length direction of the cross beam 2. Thereby, the limit protrusion 112 can better resist lateral forces and sway, thus enhancing the overall load-bearing strength of the photovoltaic module frame. At the same time, the same shape of the limit groove 21 and the protrusion 422 also ensures the accuracy and convenience of installation positioning. It should be noted here that the vertical cross-section of the limit protrusion 112 along its length direction can be L-shaped or inverted T-shaped. The present application does not limit this, as long as it can effectively limit the up and down movement of the limit protrusion 112 along the vertical direction or the movement along the length direction of the cross beam 2.

[0047] In some embodiments of the present invention, as Figure 1 , Figure 2 and Figure 4 shown, limit protrusions 112 are respectively provided on both sides of the bottom plate 11, and the two limit protrusions 112 are parallel to each other, and the limit protrusions 112 correspond to the limit grooves 21 one by one. Thereby, the movement of the photovoltaic frame 1 along the length direction of the cross beam 2 is further restricted, and at the same time, the structural strength and stability are increased.

[0048] In some embodiments of the present invention, as Figure 2 shown, the photovoltaic frame 1 further includes: a first side plate 12, a second side plate 13, an upper cross plate 14, and a top plate 15.

[0049] Among them, the first side plate 12 is arranged on the upper surface of the bottom plate 11 and extends along the length direction of the limiting protrusion 112. The second side plate 13 is arranged on the upper surface of the bottom plate 11 and is parallel to the first side plate 12. The first side plate 12 and the second side plate 13 are perpendicular to the bottom plate 11. The extension part 111 is located on the side of the second side plate 13 away from the first side plate 12 and is perpendicular to the second side plate 13. The upper cross plate 14 is parallel to the bottom plate 11 and is respectively connected to the upper end of the first side plate 12 and the top of the second side plate 13. The bottom plate 11, the first side plate 12, the second side plate 13 and the upper cross plate 14 enclose a cavity 16. The top plate 15 is parallel to the bottom plate 11 and is connected to the top of the first side plate 12. The top plate 15 is located above the upper cross plate 14 and forms an installation groove 17 between the top plate 15 and the upper cross plate 14. The installation groove 17 is used to place the corresponding photovoltaic panel. Thus, the photovoltaic frame 1 encloses the cavity 16 and the installation groove 17 through the bottom plate 11, the first side plate 12, the second side plate 13, the upper cross plate 14 and the top plate 15, forming a stable frame structure for installing and fixing the photovoltaic panel, with a simple structure, firm and reliable.

[0050] In some embodiments of the present invention, as Figure 3 shown, the photovoltaic module frame further includes: a pressing block 4. The pressing block 4 includes a first connecting portion 41 and a second connecting portion 42. The first connecting portion 41 is used to fit on the second side plate 13, and the second connecting portion 42 is used to fit on the extension portion 111. A fixing hole 421 corresponding to the connecting hole 113 is provided on the second connecting portion 42. The fastener 3 sequentially passes through the connecting hole 113, the fixing hole 421 and the mounting hole to connect the pressing block 4 and the photovoltaic frame 1 to the cross beam 2. When the limiting protrusion 112 slides into the limiting groove 21 and the connecting hole 113 of the photovoltaic frame 1 is aligned with the mounting hole on the cross beam 2, the first connecting portion 41 of the pressing block 4 is fitted to the second side plate 13, and the second connecting portion 42 is fitted to the extension portion 111, so that the fixing hole 421 of the pressing block 4 is aligned with the connecting hole 113 of the photovoltaic frame 1. Finally, the fastener 3 sequentially passes through the connecting hole 113, the fixing hole 421 and the mounting hole to connect the pressing block 4 and the photovoltaic frame 1 to the cross beam 2. Thus, by providing the pressing block 4, the connection stability between the photovoltaic frame 1 and the cross beam 2 is further enhanced, and at the same time, the vibration between the photovoltaic frame 1 and the cross beam 2 caused by external forces such as wind and snow is reduced, the service life of the photovoltaic frame 1 and the cross beam 2 is improved, and the installation and maintenance are simple and the effect is good.

[0051] In some embodiments of the present invention, as Figures 3 to 6 shown, the first connecting portion 41 and the second connecting portion 42 are connected to form an L-shaped structure. A strip-shaped groove 131 extending along the length direction of the limiting protrusion 112 is provided on the second side plate 13. A strip-shaped protrusion 411 for cooperating with the strip-shaped groove 131 is provided on the first connecting portion 41. The strip-shaped protrusion 411 can slide along the strip-shaped groove 131.

[0052] That is to say, as Figure 3 , Figure 5 and Figure 6 shown, the pressing block 4 of the L-shaped structure can disperse the pressure of the photovoltaic frame 1 from two directions (i.e., the direction perpendicular to the bottom plate 11 and the direction parallel to the bottom plate 11), preventing it from shifting or falling off due to factors such as wind force or external vibration. A strip-shaped groove 131 extending along the length direction of the limit protrusion 112 is provided on the second side plate 13, and a strip-shaped protrusion 411 for cooperating with the strip-shaped groove 131 is provided on the first connecting portion 41. The strip-shaped protrusion 411 can slide along the strip-shaped groove 131. Specifically, there can be multiple strip-shaped grooves 131 and strip-shaped protrusions 411, and the multiple parallel strip-shaped protrusions 411 and the multiple parallel strip-shaped grooves 131 can be serrated. Thus, after the strip-shaped groove 131 on the right side wall of the second side plate 13 and the strip-shaped protrusion 411 on the first connecting portion 41 are slidably connected in a matching manner, the serrated mounting surface increases the friction force between the pressing block 4 and the photovoltaic frame 1, improving the installation stability and further preventing the photovoltaic frame 1 from shifting due to external force (such as wind force).

[0053] In some embodiments of the present utility model, as Figures 3 to 6 shown, a first clamping block 412 is provided on the side of the first connecting portion 41 away from the second connecting portion 42, a first clamping groove 413 is provided on one side of the first clamping block 412, a first through hole 132 corresponding to the first clamping block 412 is provided on the second side plate 13, the first clamping block 412 can pass through the first through hole 132, and the first clamping groove 413 is used for clamping the second side plate 13. That is to say, first, the first clamping block 412 on the first connecting portion 41 is correspondingly passed through the first through hole 132 on the second side plate 13, and then the pressing block 4 is slid along the strip-shaped groove 131 until the first clamping groove 413 clamps the second side plate 13 and the fixing hole 421 corresponds to the connecting hole 113. Thus, when the photovoltaic frame 1, the cross beam 2, and the pressing block 4 are fixed by the fastener 3, on the one hand, the contact area between the pressing block 4 and the photovoltaic frame 1 is increased to disperse the stress, and on the other hand, it can further prevent the second side plate 13 from vibrating and shifting in the left-right direction, effectively enhancing the stability of the photovoltaic module frame, and at the same time, the installation is simple and the effect is good.

[0054] In some embodiments of the present utility model, as Figures 3 to 6As shown in the figure, a protruding portion 422 protruding downward is provided at one end of the second connecting portion 42 away from the first connecting portion 41. The protruding portion 422 is used to fit on the end surface of the extending portion 111 away from the second side plate 13. Thus, the design of the protruding portion 422 increases the contact points and contact area between the pressing block 4 and the extending portion 111 of the photovoltaic frame 1. On the one hand, the stress of the fastener 3 is dispersed, thereby improving the structural stability. On the other hand, the design of the protruding portion 422 protruding downward and fitting the end surface of the extending portion 111 helps to prevent the pressing block 4 from being lifted when subjected to a lateral force, helps to resist external loads such as wind and snow, and improves the structural strength of the entire photovoltaic module frame. At the same time, when the protruding portion 422 protruding downward on the pressing block 4 fits on the end surface of the extending portion 111 away from the second side plate 13, the protruding portion 422 can limit the movement of the pressing block 4 relative to the photovoltaic frame 1, and improve the accuracy of the installation and positioning of the photovoltaic frame 1 and the pressing block 4.

[0055] In some embodiments of the present invention, as Figure 1 shown, the photovoltaic frame 1 is a rectangular frame structure surrounded by four frame materials, and the photovoltaic frame 1 is an aluminum alloy photovoltaic frame 1. Thus, the aluminum alloy photovoltaic frame 1 is corrosion-resistant and lightweight, facilitating installation, maintenance and disassembly, reducing the maintenance cost of the photovoltaic module frame, and extending the service life.

[0056] According to the photovoltaic module of the second aspect embodiment of the present invention, as Figures 1 to 6 shown, it includes a laminate (i.e., a photovoltaic panel, not shown) and the photovoltaic module frame of any one of the above first aspect embodiments, and the laminate is arranged on the photovoltaic module frame. That is to say, for the photovoltaic module provided by the present invention, the photovoltaic module frame of any one of the above first aspect embodiments is adopted, and the laminate is arranged through the installation groove 17 on the photovoltaic frame 1. When the photovoltaic frame 1 is arranged on the cross beam 2, the stability of the photovoltaic frame 1 can be effectively improved, the problem of tearing of the connection hole 113 of the photovoltaic frame 1 can be avoided, and at the same time, the damage of the photovoltaic module caused by wind and snow or other external force factors can be avoided, reducing the maintenance cost. In addition, due to the good stability of the photovoltaic frame 1 of the present invention, it can be applied to environments with high load requirements, and has a wider applicability.

[0057] Based on the above embodiments of the present invention, without explicit negation or conflict, the technical features of one embodiment can be beneficially combined with one or more other embodiments.

[0058] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
