Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] In the description of this utility model, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "first feature above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "first feature above", "above" and "over" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0037] The photovoltaic module 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0038] Reference Figure 1 As shown, the photovoltaic module 100 according to an embodiment of the present utility model may include: a photovoltaic array 10.

[0039] Specifically, the photovoltaic array 10 includes a crossbeam 11 and multiple (two or more) photovoltaic panels 12, which are fixed to the crossbeam 11 and extend along the length of the crossbeam 11 (e.g., along the crossbeam 11). Figure 1 The photovoltaic panels 12 are spaced apart in the left and right directions as shown. The crossbeam 11 can fix multiple photovoltaic panels 12, which meets the required fixing requirements. The multiple photovoltaic panels 12 can form a photovoltaic array, which facilitates the conversion of solar energy into electrical energy and helps to improve the power output.

[0040] In related technologies, photovoltaic modules will vibrate under severe weather conditions, such as typhoons, strong winds, or sandstorms. Since the vibration frequency of wind is not fixed, such as strong winds including gusts, whirlwinds, and turbulence, resonance will occur when the vibration frequency of the wind is equal to the natural frequency of the photovoltaic module. The resonance force of the photovoltaic module under strong wind is 2 times or even more than 10 times that of the strong wind pressure. Therefore, under strong wind and local strong wind conditions, photovoltaic modules are easily blown off, affecting the normal use of the photovoltaic modules.

[0041] Therefore, in this utility model, as Figures 1-10 As shown, a shock-absorbing device 20 is provided between each two adjacent photovoltaic panels 12. The shock-absorbing device 20 includes a pressure block 21 and a fastening assembly 22. The pressure block 21 is located on the side of the photovoltaic panel 12 away from the crossbeam 11 (e.g., Figure 2 As shown in the diagram (upper side), the pressure block 21 abuts against two adjacent photovoltaic panels 12, allowing the pressure block 21 to limit the two adjacent photovoltaic panels 12 and apply a fastening force to the photovoltaic panels 12. The fastening component 22 connects the pressure block 21 and the crossbeam 11, which can fix the pressure block 21 and ensure the stability of the overall structure of the photovoltaic module 10. This achieves the fastening of the photovoltaic panels 12 on the crossbeam 11, enhances the structural stability and seismic performance of the photovoltaic panels 12, effectively improves the wind resistance of the photovoltaic module 100, prevents the photovoltaic module 100 from being blown off, effectively improves the durability and safety of the photovoltaic module 100 under severe weather conditions, and reduces the risk of damage caused by vibration or wind pressure.

[0042] In addition, by using a single anti-vibration device 20, the two adjacent photovoltaic panels 12 can be simultaneously limited, making the limiting of the two adjacent photovoltaic panels 12 reliable. Compared with one anti-vibration device 20 for each photovoltaic panel 12, it can reduce the space occupied and help reduce production costs.

[0043] The anti-vibration device 20 features a simple design and ingenious structure, enabling rapid and efficient installation during the installation of newly constructed photovoltaic modules 100 and the reinforcement of existing photovoltaic modules 100. Simultaneously, it facilitates subsequent maintenance and repair work, reducing maintenance costs and improving the overall operating efficiency of the photovoltaic modules 100.

[0044] For example, it is possible to install anti-vibration devices 20 on the grid-connected photovoltaic panels 12, and directly install and reinforce them without disassembling the original photovoltaic modules 100, effectively preventing the photovoltaic modules 100 from falling off due to strong winds, thereby preventing the photovoltaic panels 12 from being blown off. In addition, in the prior art, after some photovoltaic panels 12 have been blown off, the same photovoltaic panels 12 can be replaced and reinforced by the anti-vibration devices 20.

[0045] It should be noted that, for ease of description, the directions such as "left," "right," "up," and "down" in this utility model are based on the directional relationships shown in the accompanying drawings, and are not limitations on the directions in actual application.

[0046] In some embodiments, the photovoltaic panel 12 has a frame, and the pressure block 21 abuts against the frames of two adjacent photovoltaic panels 12 to ensure reliable positioning of the photovoltaic panel 12 and avoid damage to other structures of the photovoltaic panel 12, thereby ensuring the normal use of the photovoltaic panel 12.

[0047] According to the embodiment of the present invention, the photovoltaic module 100 is fixed on a crossbeam 11 by a plurality of photovoltaic panels 12 and spaced apart along the length of the crossbeam 11. The pressure block 21 of the anti-vibration device 20 is located on the side of the photovoltaic panel 12 away from the crossbeam 11 and abuts against two adjacent photovoltaic panels 12. The fastening component 22 of the anti-vibration device 20 connects the pressure block 21 and the crossbeam 11, which can fasten the photovoltaic panel 12 on the crossbeam 11, enhance the structural stability and anti-vibration performance of the photovoltaic panel 12, effectively improve the wind resistance of the photovoltaic module 100, prevent the photovoltaic module 100 from being blown off, effectively improve the durability and safety of the photovoltaic module 100 under severe weather conditions, reduce the risk of damage caused by vibration or wind pressure, and reduce production costs.

[0048] In some embodiments of this utility model, such as Figures 2-6 As shown, the fastening assembly 22 includes a bolt 221 and a nut 222. The bolt 221 passes through the pressure block 21 and the crossbeam 11 and is connected to the nut 222. The pressure block 21 and the crossbeam 11 are located between the head of the bolt 221 and the nut 222. Thus, the pressure block 21 and the crossbeam 11 can be fixed using the bolt 221 and the nut 222. The structure is simple, easy to operate, and the fastening force can be adjusted according to actual needs, ensuring the stability and reliability of the photovoltaic module 100. At the same time, it facilitates the disassembly and replacement of the photovoltaic panel 12 when needed, improving the maintainability of the photovoltaic module 100.

[0049] According to some embodiments of this utility model, such as Figures 2-6 As shown, nut 222 is located on the side of crossbeam 11 away from pressure block 21 (e.g. Figure 2 As shown on the lower side), the bolt 221 and nut 222 can be installed in the required positions, and a connector 23 is provided between the nut 222 and the crossbeam 11. The connector 23 enhances the stability of the connection and effectively prevents problems such as tearing of the mounting holes on the crossbeam 11, ensuring reliable fixing; or, the nut 222 is located on the side of the pressure block 21 away from the crossbeam 11 (e.g., the lower side). Figure 6The upper side (as shown in the diagram) can accommodate the required installation positions of bolts 221 and nuts 222, thereby allowing for the selection of different installation methods according to different installation environments and requirements, ensuring assembly flexibility.

[0050] In the embodiments of this utility model, the specific structure of the bolt 221 can be set according to the actual situation.

[0051] For example, in some embodiments, the bolt 221 can be a straight bolt 221, and there is one nut 222 connected to the straight bolt 221, which can fix the crossbeam 11 and the pressure block 21. The straight bolt 221 has a simple structure and is easy to assemble; or, as... Figure 2 and Figure 6 As shown, bolt 221 can be a U-bolt 221, and there are two nuts 222. The two nuts 222 are connected to both ends of the U-bolt 221 along its length, which can fix the crossbeam 11 and the pressure block 21. The U-bolt 221 can provide stronger fastening force in two directions, effectively improving the wind resistance of the photovoltaic module 100. Therefore, different structural forms of bolt 221 can be selected according to different usage requirements, so that the photovoltaic module 100 can better adapt to different application environments and requirements.

[0052] In some embodiments where the bolt 221 is a U-bolt 221, the two ends of the U-bolt 221 in the length direction can be located on both sides in the width direction of the crossbeam 11. This can prevent the U-bolt 221 from being inserted into the mounting hole of the crossbeam 11, which could easily cause the mounting hole to be torn, thus ensuring the reliability of the fixation.

[0053] In some specific embodiments, such as Figure 2 and Figure 6 As shown, bolt 221 is a U-bolt 221, and there are two nuts 222. The two nuts 222 are connected to the two ends of the U-bolt 221 along its length. Both nuts 222 are located on the side of the crossbeam 11 away from the pressure block 21. A connecting piece 23 is provided between the nuts 222 and the crossbeam 11. Alternatively, both nuts 222 can be located on the side of the pressure block 21 away from the crossbeam 11. Different installation methods can be selected according to different installation environments and requirements to ensure assembly flexibility.

[0054] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the fastening component 22 can be a metal wire. The metal wire can fasten the pressure block 21 and the crossbeam 11, ensuring reliable fastening. Moreover, the metal wire has flexibility and plasticity, which can flexibly adapt to various installation conditions, thereby improving the flexibility and convenience of installation, simplifying the installation process, and reducing assembly costs. For example, the metal wire can be iron wire, etc.

[0055] In some embodiments, there are multiple metal wires (two or more), which are intertwined. The multiple metal wires can improve the structural strength and ensure that the pressure block 21 and the crossbeam 11 are securely fastened.

[0056] According to some embodiments of the present invention, the fastening component 22 can be a clamp, which can fasten the pressure block 21 and the crossbeam 11. The clamp has high structural strength, ensuring reliable fastening, simplifying the assembly process, and reducing assembly costs.

[0057] In the embodiments of this utility model, the specific structure of the pressure block 21 can be set according to the actual situation.

[0058] For example, in some embodiments, such as Figure 2 and Figure 3 As shown, the end face of the pressure block 21 that abuts against the photovoltaic panel 12 is a plane. The contact between the plane of the pressure block 21 and the photovoltaic panel 12 provides stable support, ensuring reliable contact with the photovoltaic panel 12. Furthermore, the structure is simple and easy to manufacture; or, as... Figure 5 As shown, the end face of the pressure block 21 that abuts against the photovoltaic panel 12 is an arc surface. The contact between the arc surface of the pressure block 21 and the photovoltaic panel 12 can reduce stress concentration to a certain extent and improve the shock absorption effect. Therefore, it can be selected according to specific application requirements and installation environment to meet different usage needs.

[0059] For example, in some embodiments, such as Figure 2 and Figure 3 As shown, the end face of the pressure block 21 facing away from the photovoltaic panel 12 is flat. This flatness ensures the stability and reliability of the contact between the pressure block 21 and the fastening component 22, resulting in a uniform distribution of the fastening force on the fastening component 22. Furthermore, the structure is simple and easy to manufacture; or, as... Figure 4 and Figure 5 As shown, the end face of the pressure block 21 facing away from the photovoltaic panel 12 is curved. The curved surface of the pressure block 21 can disperse the stress generated by the fastening component 22, reducing damage caused by stress concentration and extending the service life of the pressure block 21 and the fastening component 22. Therefore, it can be selected according to specific application requirements and installation environment to meet different usage needs.

[0060] In some specific embodiments, such as Figure 2 and Figure 3 As shown, the end face of the pressing block 21 that abuts against the photovoltaic panel 12 is flat, and the end face of the pressing block 21 that is away from the photovoltaic panel 12 is also flat, meaning that the pressing block 21 can be formed as a cuboid; or, as shown... Figure 4As shown, the end face of the pressure block 21 that abuts against the photovoltaic panel 12 is flat, and the end face of the pressure block 21 that is away from the photovoltaic panel 12 is curved, that is, the pressure block 21 can be formed as a semi-cylinder; or, as shown Figure 5 As shown, the end face of the pressure block 21 that abuts against the photovoltaic panel 12 is an arc surface, and the end face of the pressure block 21 that is away from the photovoltaic panel 12 is also an arc surface. That is, the pressure block 21 can be formed into an arch shape, which can apply a fastening force to the photovoltaic panel 12 and meet different assembly requirements, ensuring that the photovoltaic panel 12 is reliably fixed on the crossbeam 11.

[0061] In some embodiments, by increasing the length of the pressure block 21 along the width direction of the crossbeam 11, the pressure block 21 can be applied to the photovoltaic panel 12 more evenly, ensuring more reliable fixation of the photovoltaic panel 12.

[0062] In some embodiments of this utility model, metal wires are wound around the pressure block 21 and the crossbeam 11, which can further increase additional reinforcement measures, thereby further enhancing the stability of the photovoltaic module 100 and improving the overall structural strength of the photovoltaic module 100.

[0063] According to some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the pressure block 21 includes a rotating assembly 31 and a wedge-shaped member 32. The rotating assembly 31 includes a first rotating part 311 and a second rotating part 312, which are rotatably connected, i.e., the rotating assembly 31 can form a V-shaped hinge. The ends of the first rotating part 311 and the second rotating part 312 away from each other respectively abut against two adjacent photovoltaic panels 12. The wedge-shaped member 32 is disposed between the first rotating part 311 and the second rotating part 312, and the wedge-shaped member 32 is located on the side of the first rotating part 311 and the second rotating part 312 away from the crossbeam 11 (e.g., Figure 9 (As shown on the upper side), the wedge 32 abuts against the first rotating part 311 and the second rotating part 312, and the fastening assembly 22 connects the wedge 32 and the crossbeam 11.

[0064] Therefore, through the mutual rotation adjustment of the first rotating part 311 and the second rotating part 312 and the cooperation of the wedge 32, for example, the first rotating part 311 and the second rotating part 312 can rotate towards each other to meet the situation where the gap between two adjacent photovoltaic panels 12 is small, and the first rotating part 311 and the second rotating part 312 can rotate towards each other to meet the situation where the gap between two adjacent photovoltaic panels 12 is large. This allows the pressure block 21 to solve the problem of uneven gaps between multiple adjacent photovoltaic panels 12, thereby flexibly adapting to different installation environments and meeting the installation and fastening requirements of multiple adjacent photovoltaic panels 12 with different gap widths. Moreover, the pressure block 21 has a simple structure and is easy to process and manufacture. When the photovoltaic module 100 is subjected to wind force, the rotating part 31 and the wedge 32 can evenly distribute the pressure to the photovoltaic panel 12, avoiding problems such as damage caused by excessive force on a single point. This can further enhance the fastening effect of the shockproof device 20 in local high wind areas such as wind eyes and wind outlets, ensuring the overall stability of the photovoltaic module 100.

[0065] In some embodiments, the ends of the first rotating part 311 and the second rotating part 312 that are away from each other are respectively connected to two adjacent photovoltaic panels 12 by fasteners, ensuring that the photovoltaic panels 12 are reliably connected to the first rotating part 311 and the second rotating part 312. The fastening component 22 can be a wire, which can be wrapped around the wedge-shaped member 32 and the crossbeam 11, so that the wire can fasten and compress the wedge-shaped member 32, thereby ensuring that the rotating component 31 is reliably fixed to the two adjacent photovoltaic panels 12. For example, the fastener can be a screw.

[0066] In some embodiments, as Figure 9 and Figure 10 As shown, there can be multiple wedges 32 (two or more). These multiple wedges 32 may have different shapes and / or sizes; that is, multiple wedges 32 may have different shapes, different sizes, or different shapes and sizes. The required wedges 32 can be selected according to the actual assembly situation to meet the required usage requirements. For example, the cross-sectional area of ​​the wedge 32 may be triangular or trapezoidal, etc.

[0067] In some embodiments, the wedge 32 can be a wooden part. The wedge 32 made of wood is easy to process and manufacture, ensuring reliable positioning of the rotating component 31 and helping to reduce production costs.

[0068] According to some embodiments of this utility model, such as Figure 1 As shown, there can be multiple photovoltaic modules 10, which are spaced apart along the width of the crossbeam 11. Multiple photovoltaic modules 10 can improve the power generation efficiency of the photovoltaic module 100, and enhance the flexibility and scalability of the photovoltaic module 100 to meet different usage needs.

[0069] In embodiments of this utility model, the number of photovoltaic modules 10 can be flexibly set according to actual conditions. For example, the photovoltaic modules 10 can be configured as follows: Figure 1 The number shown is two, but it can also be three, four, five, six or more, all of which are within the protection scope of this utility model.

[0070] Other configurations and operations of the photovoltaic module 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
