Description

Technical Field

[0001] This utility model relates to the field of photovoltaic solar energy technology, specifically to a photovoltaic module pressing block and a photovoltaic module. Background Technology

[0002] Photovoltaic modules generally refer to solar cell modules. Because the output voltage of a single solar cell is relatively low, and the electrodes of unencapsulated cells are prone to detachment due to environmental influences, a certain number of individual cells must be sealed in series and parallel to form a solar cell module to prevent corrosion of the cell electrodes and interconnects. In addition, encapsulation also prevents the cells from breaking and facilitates outdoor installation. The quality of encapsulation determines the lifespan and reliability of the solar cell module.

[0003] The frame is a crucial component of photovoltaic (PV) modules, primarily used for fixing and sealing them. The frame significantly impacts the module's lifespan and requires high weather resistance. Currently, commonly used frames are formed by extruding profiles using molds, with some frames incorporating clamping blocks and mounting grooves. However, existing technologies, due to structural limitations, result in unstable installation, easy slippage, and poor versatility when combining clamping blocks and frames with mounting grooves. Furthermore, because the glass surface of a full-screen module is flush with the frame interface, using conventional clamping blocks easily leads to glass breakage, making it impossible to securely install PV modules under harsh weather conditions.

[0004] For example, Chinese patent application publication number CN223109952U, filed on July 31, 2024, discloses a frameless photovoltaic module without an A-side, comprising a frame component and a pressure block component. The frame component is fixedly installed on the photovoltaic bracket by the pressure block component. The frame component includes a first side plate, a second side plate, a lower support plate, an upper support plate, and a corner bracket connecting cavity. The first side plate has a locking groove in the middle and an anti-seepage groove designed at the upper end of the locking groove. The pressure block component includes a pressure block that matches the locking groove and an anti-seepage protrusion that matches the anti-seepage groove. The locking groove has a near-parallelogram structure design. The first side plate has a first gluing area and a pressure relief area, and the upper support plate has a second gluing area. The pressure block and the locking groove cooperate to provide downward pressure, thereby pressing the frame component down. Although this technical solution has a locking groove and a pressure block that matches the locking groove, the photovoltaic module is not securely installed and is prone to shaking. Moreover, the pressure block is not very versatile and requires a pressure block of a specific size. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model

[0006] In existing photovoltaic modules, the combination of a clamping block and a frame with mounting grooves suffers from structural issues, resulting in insecure installation, easy slippage, and poor versatility. Furthermore, because the glass surface of a full-screen module is flush with the frame interface, using conventional clamping blocks easily leads to glass breakage. This invention provides a photovoltaic module clamping block with high load-bearing capacity, secure installation, anti-slip properties, and strong versatility. This invention also provides a photovoltaic module using this clamping block, ensuring secure installation, preventing slippage, and maintaining strong versatility even in harsh weather conditions, while simultaneously solving the problem of easily breakable glass.

[0009] A photovoltaic module pressing block has a pressure-bearing part at the top, a clamping part and a supporting part below the pressure-bearing part, the clamping part and the supporting part being spaced apart, the supporting part being located between adjacent clamping parts, a clearance part being provided between the clamping part and the supporting part, and a protrusion being provided at the end of the clamping part and / or the supporting part away from the pressure-bearing part.

[0010] Furthermore, the protrusion is cone-shaped.

[0011] Preferably, the shape of the protrusion is one of a pyramid, a cone, or an elliptical cone.

[0012] Furthermore, the support portion comprises two parts, namely a first support portion and a second support portion, which are arranged opposite to each other and respectively disposed on two sides of the pressure-bearing portion.

[0013] Furthermore, the pressing part includes four parts, namely a first pressing part, a second pressing part, a third pressing part and a fourth pressing part. The pressing part protrudes outward relative to the support part in the Y-axis direction, and the length of the support part in the Z-axis direction is greater than that of the pressing part. The four pressing parts are spaced apart.

[0014] Furthermore, the top of the clamping part is flush with the top of the pressure-bearing part and the top of the support part.

[0015] Furthermore, the top of the clamping part extends downward from the pressure-bearing part, and the clamping part is disposed at the middle of both ends of the support part.

[0016] Furthermore, a through hole is provided in the center of the pressure-bearing part.

[0017] A photovoltaic module includes a frame and a photovoltaic module clamping block. An installation groove is formed on the outer side wall of the frame, and the clamping part is disposed in the installation groove.

[0018] Furthermore, the outer wall of the mounting groove is located within the clearance portion of the pressure block.

[0019] Furthermore, the frame is disposed on the mounting bracket; the support portion spans the top of the mounting bracket and is disposed on the mounting bracket.

[0020] Furthermore, it also includes a bolt assembly that passes through the pressure block and fixes the pressure block to the photovoltaic module, wherein the protrusion is inserted into the photovoltaic module.

[0021] 3. Beneficial effects

[0022] Compared with existing known technologies, the technical solution provided by this utility model has the following significant advantages:

[0023] (1) The photovoltaic module pressure block provided by this utility model has a pressing part and a supporting part below the pressure bearing part, so that the pressure block is evenly stressed. The pressing part and the supporting part work together to provide more reliable support for the pressure bearing part and enhance the load-bearing capacity of the pressure block structure. The pressing part and the supporting part are arranged at intervals, and the supporting part is located between adjacent pressing parts, which increases the versatility of the pressure block and can be used for the installation of photovoltaic modules of different sizes. The protrusion increases the friction between the pressure block and the contact surface, so that the pressure block will not slide in the X-axis direction. At the same time, the protrusion penetrates into the photovoltaic module to play a role in lightning protection and is suitable for severe weather. The pressing part and the clearance part are used in conjunction with the photovoltaic module frame to prevent the pressure block from moving in the Y-axis direction.

[0024] (2) The photovoltaic module pressing block provided by this utility model has a cone-shaped protrusion. When the cone is subjected to pressure perpendicular to the axis, it will convert part of the load into compressive stress and improve the local strength. Ordinary protrusions are not sharp enough during the mold opening process, making it difficult to pierce the outer coating of the photovoltaic module frame. Setting it as a cone can effectively solve this problem.

[0025] (3) The photovoltaic module pressing block provided by this utility model includes two support parts and four pressing parts, which provides more stable support and enhances the overall load-bearing capacity of the pressing block.

[0026] (4) The photovoltaic module pressure block provided by this utility model has a pressing part with the top end of the pressing part flush with the pressure bearing part and the top end of the supporting part, which can ensure uniform pressure distribution, avoid local stress concentration, thereby improving the stability of the overall structure. The pressure block is more versatile and suitable for the installation of photovoltaic modules of different sizes.

[0027] (5) The photovoltaic module clamping block provided by this utility model has a clamping part whose top end extends downward from the pressure bearing part. The clamping part is located in the middle of both ends of the support part, which can effectively disperse the pressure and avoid stress concentration problems that may occur when the pressure bearing part and the clamping part are in direct contact, thereby improving the overall stability and reliability of the device. It can also ensure that the clamping part will not generate excessive local pressure on the pressure bearing part when it is fixed, thereby avoiding structural deformation or damage caused by excessive local force and enhancing the bending resistance of the clamping block.

[0028] (6) The photovoltaic module pressure block provided by this utility model has a through hole in the center of the pressure bearing part. When the pressure block is installed, it cooperates with the bolt assembly to fix the pressure block.

[0029] (7) The photovoltaic module provided by this utility model has a pressing part of the pressing block set in the mounting groove. The pressing part is tightly fitted with the mounting groove, so that the frame is in a fixed state. Combined with the protrusion on the pressing block, the frame and the pressing block are installed more firmly, stably and without shaking. Moreover, the use of this pressing block and mounting groove solves the problem of the glass surface of the full-screen module being easily broken under the action of conventional pressing blocks.

[0030] (8) The photovoltaic module provided by this utility model has an outer wall of the mounting groove located inside the clearance part of the pressure block, so that the support part and the outer wall of the mounting groove are also closely fitted, further ensuring the firmness of the frame.

[0031] (9) The photovoltaic module provided by this utility model has a support part that spans the top of the mounting bracket and is set on the mounting bracket. The pressure block can still be used even if the size of the mounting bracket is appropriately changed, thus enhancing the versatility of the pressure block.

[0032] (10) The photovoltaic module provided by this utility model uses a bolt assembly to pass through the pressure block and fix the pressure block to the photovoltaic module, with the protrusion inserted into the photovoltaic module. The protrusion is in close contact with the photovoltaic module, and the protrusion provided on the pressing part is in close contact with the bottom surface of the mounting groove; the protrusion provided on the support part is in close contact with the mounting bracket of the photovoltaic module. Under the action of the bolt assembly, the pressure block is slightly deformed, and the prestress between the pressure block and the frame, and between the pressure block and the mounting bracket, causes the protrusion to sink into the frame and the mounting bracket, increasing the friction and thus fixing the photovoltaic module.

[0051] Example 1

[0052] A photovoltaic module clamping block, such as Figure 1 , Figure 2 As shown, the top of the pressure block 1 is a pressure-bearing part 13. Below the pressure-bearing part 13, a clamping part 11 and a supporting part 12 are provided. The clamping part 11 and the supporting part 12 are spaced apart, with the supporting part 12 located between adjacent clamping parts 11. A clearance part 16 is provided between the clamping part 11 and the supporting part 12. The ends of the clamping part 11 and the supporting part 12 away from the pressure-bearing part 13 are provided with protrusions 15. In other embodiments, the ends of the clamping part 11 or the supporting part 12 away from the pressure-bearing part 13 are provided with protrusions 15.

[0053] The protrusion 15 is shaped like a pyramid. A pyramid is a multi-faceted cone, a type of three-dimensional polyhedron, formed by connecting each vertex of a polygon to a point outside its plane with straight line segments. The polygon is called the base of the pyramid. The name of the pyramid varies depending on the shape of the base polygon: a pyramid with a square base is called a square pyramid, a pyramid with a triangular base is called a triangular pyramid, a pyramid with a pentagonal base is called a pentagonal pyramid, and a pyramid with a hexagonal base is called a hexagonal pyramid. In this embodiment, the protrusion 15 is shaped like a rhombus pyramid, i.e., a pyramid with a rhombus-shaped base. Ordinary protrusions are not sharp enough during the mold-making process, making it difficult to pierce the outer coating of the photovoltaic module frame 2. Using a rhombus pyramid effectively solves this problem. Simultaneously, the rhombus pyramid-shaped protrusion 15 presses against the photovoltaic module frame 2, forming a polygonal recess with radial grooves. The material of the frame 2 is squeezed to both sides of the grooves, forming a natural indentation, further increasing the stability of the pressure block 1 during installation.

[0054] In some other embodiments, the protrusion 15 may also be one of a square pyramid, a triangular pyramid, a pentagonal pyramid, a hexagonal pyramid, a cone, or an elliptical pyramid.

[0055] The support part 12 includes two parts, namely the first support part 121 and the second support part 122. The two support parts 12 are arranged opposite to each other and are respectively arranged on the two sides of the pressure-bearing part 13.

[0056] The pressing part 11 includes four parts: a first pressing part 111, a second pressing part 112, a third pressing part 113, and a fourth pressing part 114. The pressing part 11 protrudes outward relative to the support part 12 in the Y-axis direction. The length of the support part 12 in the Z-axis direction is greater than that of the pressing part 11. The four pressing parts 11 are arranged at intervals. In this embodiment, the first support part 121 is arranged between the first pressing part 111 and the second pressing part 112, and the second support part 122 is arranged between the third pressing part 113 and the fourth pressing part 114.

[0057] The top of the clamping part 11 is flush with the top of the pressure-bearing part 13 and the support part 12, which ensures uniform pressure distribution and avoids local stress concentration, thereby improving the stability of the overall structure. The two support parts 12 and the four clamping parts 11 work together to provide more reliable support for the pressure-bearing part 13 and enhance the load-bearing capacity of the structure.

[0058] The pressure-bearing part 13 has a through hole 14 in the center. When installing the pressure block 1, the bolt assembly 3 can pass through the through hole 14 to press the pressure block 1.

[0059] Example 2

[0060] A photovoltaic module clamping block, with a structure basically the same as in Example 1, differs in that: Figure 5 , Figure 6 As shown, the top end of the pressing part 11 extends downward from the pressure-bearing part 13, and the top end of the pressing part 11 is lower than the top ends of the pressure-bearing part 13 and the support part 12.

[0061] In this embodiment, the structure of the pressure block 1 can be:

[0062] Pressure Dispersion: The top of the clamping part 11 extends downward from the pressure-bearing part 13 and is lower than the tops of the pressure-bearing part 13 and the support part 12. This design can effectively disperse pressure and avoid stress concentration problems that may occur when the pressure-bearing part 13 and the clamping part 11 are in direct contact, thereby improving the overall stability and reliability of the device.

[0063] Enhanced bending resistance: The top of the clamping part 11 is lower than the top of the bearing part 13 and the support part 12. This design ensures that the clamping part 11 will not exert excessive local pressure on the bearing part 13 when it is fixed, thereby avoiding structural deformation or damage caused by excessive local stress.

[0064] Example 3

[0065] A photovoltaic module, such as Figure 3 , Figure 4 and Figure 7It is known that the assembly includes a frame 2, a bolt assembly 3, a mounting bracket 4, and a photovoltaic module pressing block as in Embodiments 1 and 2. The frame 2 is mounted on the mounting bracket 4. A “┌”-shaped mounting groove 21 is opened on the outer side wall of the frame 2. The mounting groove 21 forms an opening on the outer side wall of the frame 2. The pressing part 11 is disposed in the mounting groove 21 through the opening and presses the bottom of the mounting groove 21.

[0066] Specifically, the frame 2 includes a bottom surface 23, a pressing block mounting surface 22, and a laminate mounting surface 24. The bottom surface 23 and the laminate mounting surface 24 are arranged in parallel. The pressing block mounting surface 22 is connected between the bottom surface 23 and the laminate mounting surface 24. The laminate is disposed on the laminate mounting surface 24. The frame 2 also includes a groove surface 25, which is disposed on the side of the pressing block mounting surface 22 facing the laminate mounting surface 24. The groove surface 25 and the pressing block mounting surface 22 form a "┌"-shaped mounting groove 21. The "┌"-shaped mounting groove 21 includes a horizontal part and a vertical part. In this embodiment, the groove surface 25 is an L-shaped surface. The upper end of the groove surface 25 is connected to the laminate mounting surface 24, and the lower end is connected to the pressing block mounting surface 22, so that the groove surface 25, the laminate mounting surface 24, and the pressing block mounting surface 22 together form a mounting groove 21 with a rectangular vertical part.

[0067] The frame 2 also includes a support surface 26, which is vertically disposed between the laminate mounting surface 24 and the bottom surface 23, and provides support for the frame 2.

[0068] The pressing part 11 of the pressure block 1 is inserted into the mounting groove 21 and is tightly fitted with the mounting groove 21; the outer wall of the mounting groove 21, i.e. the pressure block mounting surface 22, is set in the clearance part 16 of the pressure block 1, and the pressure block mounting surface 22 is tightly fitted with the clearance part 16, so that the support part 12 is closely fitted with the outer wall of the pressure block mounting surface 22, thereby achieving a tight fit between the frame 2 and the pressure block 1.

[0069] The pressure-bearing part 13 of the pressure block 1 has a through hole 14 in the center, and the bolt assembly 3 passes through the through hole 14 and is installed on the pressure-bearing part 13. Specifically, the bolt assembly 3 includes a bolt 31, a nut 33, and a washer 32. The head diameter of the bolt 31 is larger than the diameter of the through hole 14, and the shank diameter of the bolt 31 is smaller than the diameter of the through hole 14. The shank of the bolt 31 passes through the washer 32 and the through hole 14 and cooperates with the nut 33. During the construction and installation of the photovoltaic module, tightening the bolt assembly 3 allows the protrusion 15 to penetrate into the frame 2 and the mounting bracket 4, increasing the friction and preventing the pressure block 1 from sliding in the X, Y, and Z axis directions, thereby fixing the photovoltaic module. This allows the photovoltaic module to be installed firmly and without slippage even in harsh weather conditions, and this design and installation method of the pressure block 1 will not cause the glass surface of the full-screen module to break.

[0070] As a specific solution, the pressure block 1 can be used in combination with two frame panels 2, located between the two frame panels 2. The first pressing part 111 and the second pressing part 112 of the pressure block 1 are inserted into the mounting groove 21 of one frame panel 2, and the third pressing part 113 and the fourth pressing part 114 are inserted into the mounting groove 21 of the other frame panel 2, fitting tightly with the mounting groove 21 to make the photovoltaic module more reliably fixed. The pressure block 1 can also be used in other locations such as glass curtain walls and photovoltaic curtain walls.

[0071] The mounting bracket 4 can be a hollow tube with a limiting opening. The mounting bracket 4 is formed into a U-shaped structure by the bracket top 41, bracket side wall 42, bracket bottom surface 43, and blocking part 44. The support part 12 of the pressure block 1 spans across the bracket top 41 of the mounting bracket 4 and is set on the mounting bracket 4, and is tightly connected to the bracket top 41. Specifically, the photovoltaic module pressure block installation diagram of Embodiment 1 is shown below. Figure 3 As shown, the width of nut 33 is greater than the limiting opening of mounting bracket 4 and less than the inner diameter of bracket side wall 42. After bolt assembly 3 is tightened, nut 33 fits against the lower end of blocking part 44, bolt assembly 3 and pressure block 1 are locked together, pressure block 1 is slightly deformed, so that protrusion 15 on pressing part 11 inserts into mounting groove 21 of frame 2, and protrusion 25 on support part 12 inserts into top of bracket 41, increasing friction to make photovoltaic module installation more secure, stable and not shake.

[0072] In another embodiment, the photovoltaic module clamping block installation diagram of Example 2 is shown as follows: Figure 7 As shown, nut 33 is embedded in the limiting opening of mounting bracket 4, and nut 33 is tightly fitted with the inner wall of blocking part 44 of mounting bracket 4. Bolt assembly 3 and pressure block 1 are locked together, fixing pressure block 1 on mounting bracket 4. Under the action of bolt assembly 3, pressure block 1 is slightly deformed, so that protrusion 15 is inserted into frame 2 and mounting bracket 4, increasing friction and thus fixing photovoltaic module.

[0073] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
