[0001] This utility model relates to the technical field of photovoltaic manufacturing industry, specifically to a photovoltaic module frame and a photovoltaic module mounting frame. Background Technology

[0002] With the global emphasis on renewable energy and the acceleration of energy transition, photovoltaic (PV) modules, as one of the representatives of clean energy, are gradually becoming an important component of the global energy system. PV technology not only plays a crucial role in reducing greenhouse gas emissions, but its high energy conversion efficiency and superior environmental adaptability have also led to its widespread application globally. The widespread adoption of PV modules, especially in the field of building-integrated photovoltaics (BIPV), signifies the deep integration of buildings and energy, promoting sustainable urban development and the realization of green buildings.

[0003] In recent years, photovoltaic technology has made continuous breakthroughs, especially in material innovation and module design. Modern photovoltaic modules, through the use of new high-efficiency photoelectric materials, improved photoelectric conversion structures, and enhanced weather-resistant encapsulation technologies, exhibit higher stability and reliability in various climatic environments. Photovoltaic modules are generally installed and fixed using a mounting frame, which typically includes two long side frames, two short side frames, and four connecting brackets. The four side frames are arranged in a rectangle, and then connected at the corners using connecting brackets. One existing photovoltaic module frame mainly consists of opposing side panels and vertical panels, with the side panels being taller than the vertical panels. A top panel, middle panel, and bottom panel are spaced along the height of the side panels, with the middle and bottom panels connected to the side and vertical panels at their respective ends. The other end of the top panel is not connected to the vertical panel. This creates a slot-shaped structure with one open end for the photovoltaic module to be inserted and positioned. However, this type of photovoltaic module frame has poor bending resistance and poor installation stability. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module frame to solve the problems of poor bending resistance and poor installation stability of existing photovoltaic module frames.

[0005] In a first aspect, this utility model provides a photovoltaic module frame, including:

[0006] The support portion includes: a first support plate, a second support plate, and a base plate, wherein the first support plate and the second support plate are spaced apart along the width direction of the base plate, and their bottom ends are connected to the base plate;

[0007] The mounting part includes a top plate, a middle plate, and a first side plate. The middle plate is disposed at the top of the first support plate and the second support plate, and one end of the middle plate is connected to the second support plate, while the other end extends outward from the outside of the first support plate. The top plate is located above the middle plate. The two ends of the first side plate are respectively connected to the end of the top plate away from the second support plate and the end of the middle plate extending outward from the outside of the first support plate. The top plate, the middle plate, and the first side plate together form a slot with one end open.

[0008] Beneficial effects

[0009] The slots formed by the top plate, middle plate, and first side plate in the mounting section allow photovoltaic modules to be inserted. The support section plays a major supporting and load-bearing role. Furthermore, the portion of the first side plate and middle plate extending beyond the first support plate has a cross-sectional shape resembling a semi-T-shape. This frame structure has strong bending resistance and effectively distributes the load, enhancing the stability of the entire frame and preventing bending, deformation, or breakage under stress. Simultaneously, the semi-T-shaped frame structure increases the contact area between the frame and the air, as well as the airflow space, thereby improving the heat dissipation effect of the photovoltaic modules.

[0010] In one optional embodiment, the mounting portion further includes a second side plate disposed within the slot, the second side plate being disposed opposite to the first side plate, one end of which is connected to the top plate and the other end of which is connected to the middle plate.

[0011] Beneficial effects

[0012] The second side panel effectively enhances the overall strength and bending resistance of the frame without increasing the complexity of the overall structure, further improving the frame's ability to support photovoltaic modules and giving the frame better adaptability and durability.

[0013] In one alternative embodiment, the top plate is provided with an overflow groove near the slot opening, and the overflow groove is in communication with the slot.

[0014] Beneficial effects

[0015] The design of the overflow groove allows excess adhesive to flow quickly into the groove during photovoltaic module installation, preventing the adhesive from overflowing onto the photovoltaic module.

[0016] In one alternative embodiment, a first stripe is provided on the side of the top plate away from the middle plate.

[0017] Beneficial effects

[0018] Setting the first stripe can prevent black lines from appearing during the frame extrusion molding process, ensuring product yield.

[0019] In one alternative embodiment, a second stripe is provided on the side of the first side plate away from the second support plate.

[0020] Beneficial effects

[0021] The second stripe increases surface friction, which helps prevent slippage and enhances grip.

[0022] In one optional embodiment, the middle plate, the first support plate, the second support plate and the bottom plate together form a cavity, and two ribs are provided at intervals along the width direction of the bottom plate on both the top and bottom surfaces of the cavity.

[0023] Beneficial effects

[0024] The cavity design allows the frame to be lightweight while ensuring load-bearing capacity. The ribs inside the cavity can connect with the connecting corner brackets, limiting and fixing the brackets. At the same time, the ribs effectively prevent the frame from bending or deforming under external forces.

[0025] Secondly, this utility model also provides a photovoltaic module mounting frame, including: four connecting corner brackets, wherein two of the photovoltaic module frames are spaced apart along a first direction, and the other two photovoltaic module frames are spaced apart along a second direction, wherein the first direction is perpendicular to the second direction, and the two perpendicular photovoltaic module frames are connected by the connecting corner brackets.

[0026] Beneficial effects

[0027] The four frames are connected to each other at right angles by connecting brackets to form a stable rectangular frame structure, which can ensure the overall rigidity and strength of the installation frame and effectively prevent the photovoltaic modules from loosening or shifting due to external forces during use.

[0028] In one optional embodiment, the connecting bracket includes a right-angled insertion part and a slotted part, the slotted part being disposed at the corner of the insertion part, and the end of the insertion part being inserted into the cavity of the photovoltaic module frame.

[0029] Beneficial effects

[0030] The insertion part is designed with right angles, and its end inserts into the cavity of the photovoltaic module frame, fitting tightly to the cavity to ensure a firm connection between the frames, thereby improving the overall bending and shear resistance of the frame. The slot is located at the corner of the insertion part, which can precisely match the structure of the frame, further enhancing the stability of the connection and preventing the frame from loosening or deforming during long-term use.

[0031] In one alternative embodiment, a rivet baffle is provided on the inner side of the insertion part.

[0032] In one alternative embodiment, the slot portion is provided with a corner code slot that matches the slot of the photovoltaic module frame.

[0033] Beneficial effects

[0034] The rivet baffle on the inner side of the insertion part of the connecting corner bracket works in conjunction with the ribs in the cavity to improve the assembly tightness and tensile strength between the photovoltaic module frame and the connecting corner bracket, ensuring the stability of the photovoltaic module frame at the connection point and effectively preventing loosening or displacement of the connection caused by long-term vibration or external force.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, a photovoltaic module frame 1 is provided, comprising: a support portion 11 and a mounting portion 12; the support portion 11 includes: a first support plate 111, a second support plate 112, and a bottom plate 113, wherein the first support plate 111 and the second support plate 112 are spaced apart along the width direction of the bottom plate 113, and their bottom ends are connected to the bottom plate 113; the mounting portion 12 includes: a top plate 121, a middle plate 122, and a first side plate 123, wherein the middle plate 122 is disposed on the first support plate 113. The top of the support plate 111 and the second support plate 112, and one end of the middle plate 122 is connected to the second support plate 112, and the other end extends out of the outer side of the first support plate 111. The top plate 121 is located above the middle plate 122. The two ends of the first side plate 123 are respectively connected to the end of the top plate 121 away from the second support plate 112 and the end of the middle plate 122 extending out of the outer side of the first support plate 111. The top plate 121, the middle plate 122 and the first side plate 123 together form a slot with one end open.

[0049] The frame of a photovoltaic module is generally an extruded part, consisting of a support portion 11 and a mounting portion 12. The support portion 11 includes a first support plate 111, a second support plate 112, and a base plate 113. The first support plate 111 and the second support plate 112 are arranged at intervals along the width direction of the base plate 113 and are perpendicular to the base plate 113. The distance between the first support plate 111 and the second support plate 112 can be less than or equal to the width of the base plate 113. In this embodiment, as shown... Figure 1As shown, the distance between the first support plate 111 and the second support plate 112 is less than the width of the base plate 113. The first support plate 111 is located at the end of the base plate 113, while the second support plate 112 is located to the right of the first support plate 111, but is some distance from the other end of the base plate 113. This extension of the base plate 113 beyond the second support plate 112 facilitates the fixing of the frame to other positions using bolts or other methods. To ensure the supporting strength of the first support plate 111 and the second support plate 112, the wall thickness of the first support plate 111 and the second support plate 112 should be greater than 1 mm. The mounting part 12 includes a top plate 121, a middle plate 122, and a first side plate 123, wherein the middle plate 122 is located at the top of the first support plate 111 and the second support plate 112 and is parallel to the base plate 113. One end of the middle plate 122 is connected to the second support plate 112, and the other end extends outward beyond the edge of the first support plate 111. In other words, the width of the middle plate 112 is greater than the distance between the first and second support plates 111. The top plate 121 is positioned parallel above the middle plate 122, and the first side plate 123 is positioned vertically between the top plate 121 and the middle plate 122. Both ends of the first side plate 123 are connected to the top plate 121 and the middle plate 122, respectively, with the connection points located at the ends of the top plate 121 and the middle plate 122. The top plate 121, the middle plate 122, and the first side plate 123 together form an open slot structure. Furthermore, to ensure the load-bearing capacity of the mounting part 12, the length of the connection between the middle plate 122 and the first side plate 123 and the first support plate 111 is set to 2-6 mm.

[0050] The edge of the photovoltaic module 3 is inserted into the slot and fixed by the mounting part 12. The slot-shaped structure design can precisely fit the edge of the photovoltaic module 3, keeping the photovoltaic module 3 stable after installation. The bottom support provides strength support for the overall frame, supporting and stabilizing the photovoltaic module 3. The cross-sectional shape of the first side plate 123 and the middle plate 122 extending out of the first support plate 111 is approximately semi-T-shaped, which has strong bending resistance and prevents the frame from bending, deforming or breaking under stress. In addition, the semi-T-shaped frame structure can also increase the contact area between the frame and the air and the air circulation space, which is beneficial to improving the heat dissipation effect of the photovoltaic module 3.

[0051] In one embodiment, the mounting part 12 further includes a second side plate 124 disposed in the slot. The second side plate 124 is disposed opposite to the first side plate 123, with one end connected to the top plate 121 and the other end connected to the middle plate 122.

[0052] like Figure 1As shown, a second side plate 124 is added inside the slot, giving the mounting part 12 stronger limiting and support capabilities. The second side plate 124 is arranged opposite to the first side plate 123, and its two ends are connected to the top plate 121 and the middle plate 122 respectively, making the internal space of the slot more stable. At the same time, the first side plate 123, the second side plate 124, the top plate 121, and the middle plate 122 together form the upper cavity 125 structure. The upper cavity 125 structure gives the frame mounting part 12 higher structural strength and also saves the amount of frame material used. The upper cavity 125 can leave a certain corner bracket wall thickness value for the connecting corner bracket 2 during the subsequent mounting frame assembly process, ensuring that the mounting frame can directly match the right-angle photovoltaic module 6. To ensure that a thickness value of 1-5mm can be left for the corner bracket wall thickness in the connecting corner bracket 2, the distance between the first side plate 123 and the second side plate 124 is 4-10mm.

[0053] The second side plate 124 further increases the bending rigidity of the slot and the compatibility of the photovoltaic module 3. The photovoltaic module frame 1 can be directly matched and installed with the right-angle photovoltaic module 3 without the need to round the corners of the photovoltaic module 3.

[0054] In other embodiments, such as Figure 2 As shown, the second side plate 124 can also be omitted, and the photovoltaic module frame 1 can be directly matched and clamped to the rounded corner photovoltaic module 3.

[0055] In one embodiment, the top plate 121 is provided with an overflow groove 1211 near the slot opening end, and the overflow groove 1211 is connected to the slot.

[0056] An overflow groove 1211 is located on the side of the extension end of the top plate 121 near the slot opening and communicates with the slot. When the photovoltaic module 3 is inserted into the slot, the edge of the module forms a sealed connection with the surface inside the slot. At this time, the adhesive applied in the slot may produce excess adhesive due to compression. The overflow groove 1211 on the top plate 121 can guide this excess adhesive into the overflow groove. The width and depth of the overflow groove 1211 can accommodate the excess adhesive that overflows during installation and ensure that the adhesive does not overflow onto the photovoltaic module 3. The transition between the edge of the extension end of the top plate 121 and the overflow groove 1211 is smoothed to ensure that the flow of the adhesive or the edge of the module will not be hindered during the installation of the photovoltaic module 3.

[0057] In one embodiment, a first stripe 1212 is provided on the side of the top plate 121 away from the middle plate 122.

[0058] like Figure 1 As shown, a wavy first stripe 1212 is provided on the upper side of the top plate 121 to prevent black lines from appearing on the frame during the extrusion molding process. Of course, in other embodiments, the first stripe 1212 can be dotted or raised.

[0059] In one embodiment, a second stripe 1231 is provided on the side of the first side plate 123 away from the second support plate 112.

[0060] like Figure 1 As shown, a second stripe 1231 is provided on the outer side of the first side plate 123, and the second stripe 1231 is also wavy. The second stripe 1231 is arranged in the outer area of ​​the first side plate 123, which can increase the friction of the outer surface of the frame, prevent the frame from sliding during installation, and enhance the grip of the frame. Of course, in other embodiments, the second stripe 1231 can be dotted or raised.

[0061] In one embodiment, the middle plate 122, the first support plate 111, the second support plate 112 and the bottom plate 113 together form a cavity 114, and two ribs 1141 are provided at intervals along the width direction of the bottom plate 113 on both the top and bottom surfaces of the cavity 114.

[0062] The cavity 114 is formed by a middle plate 122, a first support plate 111, a second support plate 112, and a bottom plate 113. Two ribs 1141 are evenly spaced on the top and bottom surfaces of the cavity 114. The cross-sectional shape of the rib 1141 is an isosceles trapezoid, and the long side of the isosceles trapezoid is connected to the wall of the cavity 114. The rib 1141 can increase the connecting friction force for the connecting corner bracket 2 during the assembly of the installation frame, and limit and fix the connecting corner bracket 2. At the same time, it makes the frame have higher strength and rigidity.

[0063] According to an embodiment of the present invention, another aspect provides a photovoltaic module mounting frame, including: four photovoltaic module frames 1 and four connecting brackets 2, wherein two photovoltaic module frames 1 are spaced apart along a first direction, and the other two photovoltaic module frames 1 are spaced apart along a second direction, the first direction and the second direction are perpendicular, and the two perpendicular photovoltaic module frames 1 are connected by the connecting brackets 2.

[0064] The photovoltaic module mounting frame consists of four photovoltaic module frames 1 and four connecting brackets 2. The structure of the photovoltaic module frame 3 is the same as that of the photovoltaic module frame 1 in the above embodiment. Generally, two of the four photovoltaic module frames 1 are long frames, and the other two are short frames. The two long frames can be along a first direction (e.g., Figure 5 The two side borders are arranged at intervals as shown in the middle (x), and the other two are short borders that can be arranged along the second direction (e.g., x). Figure 5 The four photovoltaic module frames 1 are arranged at intervals (as shown in the diagram), with the first direction and the second direction perpendicular to each other. The four photovoltaic module frames 1 are arranged in a rectangle to match the shape of the photovoltaic module 3. Four connecting corner brackets 2 are set at the four corners of the rectangle, and the frames are connected to the ends of two perpendicular frames through the connecting corner brackets 2, finally splicing them into a complete installation frame.

[0065] The photovoltaic module frame 1 is securely connected via connecting brackets 2, forming a complete installation frame structure. The overall frame structure has high rigidity and bending resistance, providing reliable support during the installation and use of the photovoltaic module 3. Meanwhile, the installation method of connecting brackets 2 is simple and quick, significantly reducing the complexity and time cost of the installation process and improving installation efficiency.

[0066] In one embodiment, the connecting corner bracket 2 includes a right-angled insertion part 21 and a slot part 22. The slot part 22 is disposed at the corner of the insertion part 21, and the end of the insertion part 21 is inserted into the cavity 114 of the photovoltaic module frame 1.

[0067] The two end shells of the insertion part 21 are respectively inserted into the cavities 114 of the frames 1 of two adjacent photovoltaic modules. The slot part 22 is inserted into the corner of the insertion part 21 and can accommodate the corner of the photovoltaic module 3.

[0068] In one embodiment, a rivet baffle 211 is provided on the inner side of the insertion part 21.

[0069] The inner side of the insertion portion 21 of the connecting bracket 2 is provided with multiple serrated rivet baffles 211. These rivet baffles 211 are integrally formed with the insertion portion 21 and distributed along the inner side of the insertion portion 21. The rivet baffles 211 can lock with the inner wall of the cavity 114 of the photovoltaic module frame 1, preventing the insertion portion 21 from coming out or loosening due to vibration or external force during use. Simultaneously, the ribs 1141 provided on the top and bottom surfaces of the cavity 144 of the frame can generate mechanical friction and contact pressure with the upper and lower surfaces of the insertion portion 21 of the connecting bracket 2, limiting the insertion portion 21 of the connecting bracket 2 and enhancing the stability of the connection.

[0070] In one embodiment, the slot portion 22 is provided with a corner code slot 221 that matches the slot of the photovoltaic module frame 1.

[0071] The slot portion 22 has corner bracket slots 221, which match the shape of the photovoltaic module 3. That is, the photovoltaic module 3 with right-angled corners is provided with right-angle corner bracket slots 221, while the photovoltaic module 3 with rounded corners is provided with rounded corner bracket slots 221. The corner bracket slots 221 of the slot portion 22 are connected to the slots of the photovoltaic module frame 1. The photovoltaic module frame 1 can fix the main part of the photovoltaic module 3, while the connecting corner brackets 2 can fix the corners of the photovoltaic module 3.

[0072] In addition, the slot portion 22 is provided with an upper rounded corner 222 and a lower rounded corner 223 at the matching structure between the mounting portion 12 and the support portion 11 of the photovoltaic module frame 1.

[0073] The installation process of the photovoltaic module mounting frame is described below:

[0074] First, insert the edge of the photovoltaic module 3 into the slot of a long frame. Adjust the position of the photovoltaic module 3 so that it is fully inserted into the slot and fits tightly against the inner wall of the slot. Next, align one end of the long frame with the insertion part 21 of the connecting bracket 2, inserting the bracket insertion part 21 into the cavity 114 of the long frame. During insertion, ensure the connecting bracket 2 fits tightly against the frame, pressing gently until the rivet baffle 211 is fully engaged in the cavity 114, forming a stable connection. Secure the cavity 144 on one side of the short frame to the other insertion part 21 of the connecting bracket 2 that was previously connected to the long frame. Simultaneously, insert the edge of the photovoltaic module 3 into the slot of the short frame, aligning the cavity 114 of the short frame with the insertion part 21 of the connecting bracket 2, again ensuring the rivet baffle 211 is accurately engaged in the cavity 114. After securing the two adjacent sides of the photovoltaic module 3, secure the other two sides in the same manner. After securing, connect and secure the two unconnected diagonals using two connecting brackets 2, and check that each connection point is secure. To increase the fixing strength of the photovoltaic module 3, adhesive is applied inside the slot, and excess adhesive is collected in the adhesive overflow groove 1211 to keep the mounting part 12 clean and tidy.

[0075] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
