[0037] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements.

In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0038] As Figures 1 to 3 shown, the present utility model provides a pressing block for fixing the frame 500 of a photovoltaic module, including a support section 100, a pressing section 200, and a fixing member 300; one end of the support section 100 is connected to one end of the pressing section 200, and a retaining edge 400 is provided at the end of the pressing section 200 away from the support section 100; a fixing space is formed between the retaining edge 400 and the support section 100, the frame 500 of the photovoltaic module is located in the fixing space, and a gap 401 is formed between the retaining edge 400 and the frame 500 of the photovoltaic module; the projection of the retaining edge 400 on the plane where the support section 100 is located coincides at least partially with the projection of the frame 500 of the photovoltaic module on the plane of the support section 100; the frame 500 of the photovoltaic module has an upper top wall and side walls, the upper top wall is in contact with the pressing section 200, and the side walls are in contact with the support section 100; the fixing member 300 is provided on the support section 100 for locking the pressing block on the upper top wall of the frame 500 of the photovoltaic module.

[0039] In this embodiment, the pressing block includes a supporting section 100, a pressing section 200, and a fixing member 300. The pressing block and the photovoltaic module frame 500 are fixed on the purlin through the fixing member 300 provided on the supporting section 100, and then the pressing block is locked on the upper surface of the photovoltaic module frame 500. One end of the supporting section 100 is connected to the end of the pressing section 200, so as to ensure that the supporting section 100 provides a supporting force for the pressing section 200 to facilitate the pressing section 200 to fix the photovoltaic module frame 500. And a stop edge 400 is provided at the end of the pressing section 200 away from the supporting section 100. One end of the stop edge 400 is connected to the pressing section 200, and the other end is located on the side of the photovoltaic module frame 500 away from the supporting section 100, which is used to limit the extreme position of the photovoltaic module frame 500. Through the above-mentioned stop edge 400, the photovoltaic module can be effectively prevented from slipping, and then a gap 401 is formed between the stop edge 400 and the upper surface of the photovoltaic module frame 500. By forming the above gap 401, as Figure 4 shown, when the photovoltaic module frame 500 is locked and stressed by the pressing block, there is a certain buffer space, which can effectively release the strain on the upper surface of the photovoltaic module frame 500 and reduce the stress concentration, thereby improving the reliability of the photovoltaic module.

[0040] Optionally, the bottom of the supporting section and the bottom of the photovoltaic module frame are both arranged on the purlin, and the fixing member passes through the supporting section and then connects with the purlin, which is used to lock the pressing block on the upper top wall of the photovoltaic module frame.

[0041] Preferably, the length of the pressing section 200 is less than the length of the upper surface of the photovoltaic module frame 500, so as to effectively increase the space ratio of the gap 401, so as to achieve the effect of releasing the strain on the upper surface of the photovoltaic module frame 500 and minimizing the stress concentration.

[0042] As Figure 4 shown, a gap 401 is formed between the upper surface of the photovoltaic module frame 500 and the lower surface of the stop edge 400. During use, when the back of the photovoltaic module is loaded (G), the above gap 401 provided on the photovoltaic module frame 500 can release the strain, so as to reduce the stress concentration and avoid the damage and failure of the photovoltaic module material.

[0043] By providing a certain above-mentioned gap 401 above the photovoltaic module frame 500, the concentrated stress of the photovoltaic module frame 500 on the surface of the photovoltaic module (i.e., the brittle glass surface) can be effectively reduced, and the risk of the photovoltaic module bursting can be reduced.

[0044] Among them, optionally, as Figure 2 and Figure 3As shown, when the pressing block is a middle pressing block, a pressing section 200 is respectively arranged at both ends of the supporting section 100 to act on the photovoltaic module frames 500 on both sides. Similarly, when the pressing block is a side pressing block, only one pressing section 200 is arranged at one end of the supporting section 100 to act on the adjacent photovoltaic module frames 500. Their working principles are the same, so they will not be elaborated here. Their aims are all not to deviate from the design concept of the present invention and should belong to the protection scope of the present invention.

[0045] According to an embodiment provided by the present invention, as Figure 1 and Figure 2 shown, a groove 600 is formed at the connection between the pressing section 200 and the edge stop 400. The opening of the groove 600 faces the edge stop 400, and the lower surface of the pressing section 200 below the groove 600 is used to contact the upper surface of the photovoltaic module frame 500.

[0046] In this embodiment, a groove 600 is formed at the connection between the pressing section 200 and the edge stop 400, and the opening of the groove 600 faces the side of the edge stop 400. The lower surface of the pressing section 200 below the groove 600 is used to contact the upper surface of the photovoltaic module frame 500. When locking the pressing block, by setting the above-mentioned groove 600, the lever arm length when the pressing block is stressed can be effectively reduced, making the torque smaller, thereby reducing the deformation of the upper surface of the photovoltaic module frame 500.

[0047] According to an embodiment provided by the present invention, as Figure 1 and Figure 2 shown, a reduced rigidity area 601 is formed by the groove 600 between the pressing section 200 and the edge stop 400, and the reduced rigidity area 601 can reduce the deformation of the upper surface of the photovoltaic module frame 500.

[0048] In this embodiment, a reduced rigidity area 601 is formed by the groove 600 between the pressing section 200 and the edge stop 400. Through the cooperation of the reduced rigidity area 601 and the gap 401, the deformation space above the photovoltaic module frame 500 is increased. Through deformation, stress can be effectively released. When the photovoltaic module is subjected to an external load, it will deform, thereby redistributing the internal stress. Through deformation, the stress concentration inside the material can be alleviated and released, thus avoiding the damage and failure of the material.

[0049] As Figure 4 shown, by setting the above-mentioned reduced rigidity area 601, when the pressing block is locked by the fixing member 300 and the force on the pressing block is the same, the length of the existing lever arm is less than the lever arm length when the reduced rigidity area 601 is not set, thereby making the torque smaller, the deformation of the upper surface of the photovoltaic module frame 500 smaller, and reducing the compressive force borne by the photovoltaic module (i.e., the compressive force borne by the glass surface is reduced), so as to improve the reliability of the photovoltaic module.

[0050] Among them, the size of the rigidity reduction area 601 can be set according to the actual usage requirements for the size of the groove 600. Its purpose does not deviate from the design concept of the present utility model and should fall within the protection scope of the present utility model.

[0051] According to an embodiment provided by the present utility model, as Figure 1 and Figure 2 shown, the fixing member 300 includes a fixing bolt, and the fixing bolt passes through the pressing section 200 and is connected to the purlin to fix the pressing block.

[0052] In this embodiment, the fixing member 300 includes a fixing bolt, and by using the fixing bolt, the effect of fixing the pressing block on the frame 500 of the photovoltaic module is achieved.

[0053] According to an embodiment provided by the present utility model, as Figure 1 and Figure 2 shown, the pressing section 200 is provided with a connection hole, and the fixing bolt passes through the connection hole and cooperates with the screw hole on the purlin to fix the pressing block.

[0054] In this embodiment, the pressing section 200 is provided with a connection hole. By using a fixing bolt to pass through the connection hole and cooperate with the screw hole opened on the purlin, the effect of fixing the pressing block and fixing the pressing block on the upper surface of the frame 500 of the photovoltaic module is achieved. Among them, preferably, a fixing nut is correspondingly arranged inside the purlin, and the fixing bolt cooperates with the fixing nut to fix the pressing block and the frame 500 of the photovoltaic module.

[0055] According to an embodiment provided by the present utility model, as Figure 1 and Figure 2 shown, a gasket is further provided between the bolt head of the fixing bolt and the pressing section 200.

[0056] In this embodiment, a gasket is further arranged between the bolt head of the fixing bolt that fixes the pressing section 200 on the upper surface of the frame 500 of the photovoltaic module and the corresponding pressing section 200. By arranging the above gasket, not only can the connection stability between the pressing section 200 and the frame 500 of the photovoltaic module be improved, but also it can be ensured that the pressing block will not be damaged when using the fixing bolt, and its service life can be extended.

[0057] According to an embodiment provided by the present utility model, as Figure 1 and Figure 2 shown, an anti-slip portion is provided on the surface of the pressing section 200 close to the frame 500 of the photovoltaic module.

[0058] In this embodiment, an anti-slip portion is provided on the surface of the pressing section 200 close to the frame 500 of the photovoltaic module. By providing the anti-slip portion, the friction between the pressing section 200 and the frame 500 of the photovoltaic module can be increased, thereby further strengthening the prevention of slippage. The anti-slip portion cooperates with the edge 400 so that the frame 500 of the photovoltaic module can be stably fixed at the corresponding position.

Among them, preferably, a plurality of anti-slip grooves 700 are provided, and the plurality of anti-slip grooves 700 together form the anti-slip portion to enhance the friction between the pressing block and the frame 500 of the photovoltaic module.

[0061] Among them, optionally, the anti-slip portion can also be provided as anti-slip teeth, anti-slip strips or other anti-slip settings of other shapes. As long as the purpose does not deviate from the design concept of the present utility model, it should fall within the protection scope of the present utility model.

[0062] According to an embodiment provided by the present utility model, as Figure 1 and Figure 2 shown, a buffer portion is further provided between the anti-slip groove 700 and the upper surface of the frame 500 of the photovoltaic module.

[0063] In this embodiment, a buffer portion is further provided between the anti-slip groove 700 and the upper surface of the frame 500 of the photovoltaic module. The buffer portion further plays a buffering effect, and at the same time, it can also achieve the function of releasing stress. By the cooperation of the buffer portion and the gap 401, the alleviation and release effect of stress concentration can be greatly improved, thereby protecting the material and preventing the damage and failure of the photovoltaic module material.
