[0049] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0050] It should be noted that, for the convenience of description and understanding, in this embodiment, "up" and "down" are referenced based on the state of the photovoltaic module during normal use. The direction facing the ground of the photovoltaic module is down, and the direction away from the ground is up. The vertical direction is the up-and-down direction.

[0051] It should be noted that, please refer to Figure 1 or Figure 2 , the laminate 10 in this embodiment includes a front panel 11, a first adhesive layer, a battery cell, a second adhesive layer, and a back panel 12 that are sequentially connected and arranged. When the photovoltaic module is in normal use, the front panel 11 usually faces away from the ground, so that it can receive sunlight to a greater extent. Therefore, the front panel 11 in this embodiment is set as a light-transmitting plate, specifically, for example, a glass plate, so that sunlight can pass through the front panel 11 and irradiate the battery cell, thereby realizing power generation. In addition, when the photovoltaic module is in normal use, the back panel 12 usually faces the ground. Therefore, it can be set as either a light-transmitting plate or an opaque plate, which is not limited herein.

[0052] The laminate 10 specifically includes two types: a double-glass laminate and a single-glass laminate. For the double-glass laminate, the back panel 12 is specifically set as a light-transmitting plate, so that the light on the back surface 14 of the laminate 10 can also pass through the back panel 12 and irradiate the battery cell, thereby improving the photoelectric efficiency. For the single-glass laminate, the back panel 12 can correspondingly be set as an opaque plate.

[0053] Among them, please refer to Figure 1 , the size of the back panel 12 can be the same as that of the front panel 11. After the back panel 12 and the front panel 11 are stacked together, the outer peripheral contour (i.e., the end face 13) of the back panel 12 and the outer peripheral contour (i.e., the end face 13) of the front panel 11 are aligned with each other in the thickness direction of the laminate 10.

[0054] Of course, please refer to Figure 2, the size of the back plate 12 can also be larger than that of the front panel 11. For example, the width of the back plate 12 is greater than the width of the front panel 11, or the length of the back plate 12 is greater than the length of the front panel 11, or the width and length of the back plate 12 are respectively greater than the width and length of the front panel 11, which can be specifically set according to actual needs. When the size of the back plate 12 is larger than that of the front panel 11, there is a dislocation between the back plate 12 and the front panel 11 in the thickness direction of the laminate 10. In other words, at least one side of the back plate 12 protrudes into the area outside the front panel 11. Specifically, the back plate 12 is provided with a protruding portion 121 that protrudes outside the front panel 11.

[0055] Refer to Figure 3 And Figure 6 , Figure 3 shows the structural diagram of the photovoltaic module of the first embodiment of the present application. Figure 4 shows Figure 3 the enlarged structural diagram at A. Figure 5 shows Figure 3 the structural diagram of the frame body 21 and the clamping structure 22 in the photovoltaic module shown. Figure 6 shows Figure 3 the structural diagram of the limiting member 23 in the photovoltaic module shown. Figure 5 shows the structural diagram of the photovoltaic module of the second embodiment of the present application. A photovoltaic frame 20 provided in an embodiment of the present application is used to install the laminate 10, and the photovoltaic frame 20 is provided with a supporting surface 241 for supporting the laminate 10. In other words, the assembly relationship of the laminate 10 on the photovoltaic frame 20 is that the back surface 14 of the laminate 10 (that is, the side of the back plate 12 facing away from the front panel 11) is lapped on the supporting surface 241. In this way, by supporting the edge of the back surface 14 of the laminate 10 through the supporting surface 241, a stable support can be formed for the laminate 10.

[0056] Exemplarily, the photovoltaic frame 20 includes a frame body 21 and a clamping structure 22.

[0057] The clamping structure 22 is connected to the frame body 21. Optionally, the clamping structure 22 and the frame body 21 are integrally formed by extrusion, for example. Exemplarily, the clamping structure 22 and the frame body 21 are integrally formed by aluminum extrusion. In this way, batch processing of the clamping structure 22 and the frame body 21 can be realized, and the combined structure of the clamping structure 22 and the frame body 21 is stable and reliable.

[0058] Specifically, the clamping structure includes a first clamping portion 222 and a second clamping portion 223. The first clamping portion 222 and the second clamping portion 223 are connected to the frame body 21 at intervals. The first clamping portion 222 and the second clamping portion 223 cooperate to form a clamping groove 221.

[0059] In addition, the photovoltaic frame 20 further includes a limiting member 23. The limiting member 23 includes a clamping portion 231. The clamping portion 231 is clamped and installed inside the clamping groove 221, so that the limiting member 23 is clamped and connected to the clamping structure 22, that is, the limiting member 23 can be stably assembled onto the photovoltaic frame 20. The limiting member 23 further includes a limiting portion 232, and the limiting portion 232 is connected to the clamping portion 231. Optionally, the limiting member 23 is formed by extrusion molding, injection molding or other processing methods, and can be flexibly adjusted and set according to actual requirements.

[0060] After the clamping portion 231 of the limiting member 23 is assembled into the inside of the clamping groove 221, the limiting portion 232 is, for example, located outside the clamping groove 221, that is, there is no need to be further pressed into the inside of the clamping groove 221. The limiting portion 232 is in abutting fit with the portion of the clamping structure 22 facing away from the frame body 21 (that is, the top surface of the clamping structure 22). In this way, on the one hand, during the assembly process of the limiting member 23, it can be correspondingly judged whether the installation of the limiting member 23 on the clamping structure 22 is in place according to whether the limiting portion 232 abuts against and limits the clamping structure 22, so as to judge whether the limiting member 23 presses the laminate 10; on the other hand, when the limiting portion 232 abuts against the portion of the clamping structure 22 facing away from the frame body 21, the clamping portion 231 can be stably clamped and installed inside the clamping groove 221, and the installation stability of the limiting member 23 on the photovoltaic frame 20 is relatively high.

[0061] In this embodiment, the limiting portion 232 abuts against the portion of the first clamping portion 222 facing away from the frame body 21, and the limiting portion 232 also abuts against the portion of the second clamping portion 223 facing away from the frame body 21. In other words, the width of the limiting portion 232 is greater than the width of the clamping portion 231, and the clamping portion 231 is connected to the middle portion of the limiting portion 232, so that the opposite ends of the limiting portion 232 along its width direction W (as Figure 6 shown) protrude from the clamping portion 231 respectively. The opposite ends of the limiting portion 232 along its width direction W are respectively pressed against the first clamping portion 222 and the second clamping portion 223.

[0062] The limiting part 232 is also used to abut against the end face 13 of the laminate 10 and be in limiting cooperation with the end face 13 in the thickness direction of the laminate 10. Specifically, the limiting part 232 can either abut against the end face 13 of the front panel 11 and be in limiting cooperation with the end face 13 in the thickness direction of the laminate 10, or abut against the end face 13 of the back panel 12 and be in limiting cooperation with the end face 13 in the thickness direction of the laminate 10, or can respectively abut against the end face 13 of the front panel 11 and the end face 13 of the back panel 12 and be in limiting cooperation with the end face 13 in the thickness direction of the laminate 10. In this way, the limiting part 232 plays a limiting role on the laminate 10, preventing the laminate 10 from detaching from the photovoltaic frame 20 in its thickness direction, so that the laminate 10 is stably installed on the photovoltaic frame 20.

[0063] A guiding surface 2321 is provided at the part of the limiting member 23 facing away from the frame body 21. The distance between the guiding surface 2321 and the supporting surface 241 is set as S1, and the thickness of the laminate 10 is set as D, where S1 ≤ D. In this way, the guiding surface 2321 can be flush with the front face 15 of the laminate 10 or slightly lower than the front face 15 of the laminate 10, so as to facilitate guiding and draining the rainwater on the laminate 10 and facilitating removing the dust accumulated on the front face 15 of the laminate 10.

[0064] Exemplarily, the guiding surface 2321 can be set as a plane and, for example, be flush with the front face 15 of the laminate 10. In this way, it can also facilitate guiding and draining the rainwater on the laminate 10 and facilitating removing the dust accumulated on the front face 15 of the laminate 10. In addition, a full-screen design can be realized, it can be installed horizontally and vertically, and the dust-proof effect is better. In addition, a chamfer can be provided, for example, on the side of the guiding surface 2321 facing away from the laminate 10. The rainwater is more likely to be drained under the guidance of the chamfer, and it is not easy to hurt the hand during the installation process.

[0065] Exemplarily, the guiding surface 2321 can also be set as an inclined surface or a curved surface, and the distance between the guiding surface 2321 and the supporting surface 241 shows a decreasing trend in the direction away from the laminate 10. In this way, similar to the structural form where the guiding surface 2321 is set as a plane, it can also facilitate guiding and draining the rainwater on the laminate 10 and facilitating removing the dust accumulated on the front face 15 of the laminate 10.

[0066] Exemplarily, the guiding surface 2321 can also be set as a combination form of a plane and an inclined surface or an arc. It can also play a role in guiding rainwater.

[0067] Exemplarily, the guiding surface 2321 can also be set as a surface of other regular or irregular shapes, which can be flexibly adjusted and set according to actual needs and will not be limited here.

[0068] The above-mentioned photovoltaic frame 20, on the one hand, the limiting member 23 is installed inside the card slot 221 through the clamping portion 231 to achieve the clamping cooperation with the clamping structure 22. At the same time, the limiting member 23 abuts against the end face 13 of the laminating member 10 through the limiting portion 232 and is in limiting cooperation with the end face 13 in the thickness direction of the laminating member 10, so as to stably install the laminating member 10 on the supporting surface 241 and prevent the laminating member 10 from disengaging from the photovoltaic frame 20 upwards; on the other hand, during the process of inserting the clamping portion 231 of the limiting member 23 into the inside of the card slot 221 from top to bottom, both opposite ends of the limiting portion 232 in the width direction W can be stressed, and the stress is relatively balanced, which is convenient for quickly and firmly assembling the limiting member 23 onto the photovoltaic frame 20; in addition, a guiding surface 2321 is provided on the side of the limiting member 23 facing away from the frame main body 21, and the guiding surface 2321 is arranged above the first clamping portion 222 and the second clamping portion 223. Since S1 ≤ D, the guiding surface 2321 will not protrude upwards from the front surface 15 of the laminating member 10, that is, the guiding surface 2321 is flush with or slightly lower than the front surface 15 of the laminating member 10. Thus, the dust on the front surface 15 of the laminating member 10 is easily washed away by rainwater to achieve self-cleaning of the photovoltaic module, which can reduce the operation and maintenance cost and effectively prevent dust accumulation.

[0069] Please refer to Figures 4 to 6 , on the basis of the foregoing embodiment, the clamping portion 231 is connected to the middle portion of the limiting portion 232, and a first abutting surface 2322 and a second abutting surface 2323 are provided on the portion of the limiting portion 232 facing the frame main body 21. The first abutting surface 2322 and the second abutting surface 2323 are respectively located on opposite sides of the clamping portion 231. The first abutting surface 2322 abuts against the portion of the first clamping portion 222 facing away from the frame main body 21, and the second abutting surface 2323 abuts against the portion of the second clamping portion 223 facing away from the frame main body 21. With such a setting, on the one hand, during the process of inserting the clamping portion 231 of the limiting member 23 into the inside of the card slot 221 from top to bottom, both opposite ends of the limiting portion 232 in the width direction W can be stressed, and the stress is relatively balanced, which is convenient for quickly and firmly assembling the limiting member 23 onto the photovoltaic frame 20; on the other hand, a guiding surface 2321 is provided on the side of the limiting member 23 facing away from the frame main body 21, and the guiding surface 2321 is arranged above the first clamping portion 222 and the second clamping portion 223 in the thickness direction of the laminating member 10, so that it is convenient to better guide and drain the rainwater outwards. In addition, the first abutting surface 2322 abuts against the portion of the first clamping portion 222 facing away from the frame main body 21, and the second abutting surface 2323 abuts against the portion of the second clamping portion 223 facing away from the frame main body 21, which can achieve a relatively high installation stability of the limiting member 23 on the clamping structure 22, and it is not easy to shake and fall off, thereby improving the installation stability of the laminating member 10 on the photovoltaic frame 20.

[0070] Specifically, the first abutting surface 2322, the second abutting surface 2323, the portion of the first clamping portion 222 facing away from the frame body 21, and the portion of the second clamping portion 223 facing away from the frame body 21 are all arranged as flat surfaces. In this way, the mounting stability of the limiting member 23 on the clamping structure 22 is relatively high, and it is not easy to shake or fall off, thereby improving the mounting stability of the laminate 10 on the photovoltaic frame 20.

[0071] On the basis of the foregoing embodiment, the photovoltaic frame 20 further includes a support portion 24. The support portion 24 is connected to the frame body 21, and a support surface 241 is provided on a side of the support portion 24 facing away from the frame body 21. In this way, the back surface 14 of the laminate 10 is lapped on the support portion 24, and the mounting stability can be ensured under the support of the support portion 24.

[0072] Exemplarily, the support portion 24, the frame body 21, and the clamping structure 22 are integrally formed by extrusion. Specifically, the support portion 24, the frame body 21, and the clamping structure 22 are integrally formed by extrusion using, for example, aluminum.

[0073] Optionally, the support portion 24 includes a first support member 242 and a second support member 243. The two opposite sides of the first support member 242 are respectively connected to the frame body 21 and the second support member 243. The support surface 241 is specifically formed on the second support member 243. The specific shapes of the first support member 242 and the second support member 243 can be flexibly adjusted and set independently according to their respective actual needs, including but not limited to being set as plate members. As a specific example, both the first support member 242 and the second support member 243 are support plates and are arranged at an angle to each other. The angles formed by the first support member 242 and the second support member 243 include but are not limited to 30°, 45°, 60°, 90°, 120°, or 150°, etc. In this embodiment, the first support member 242 and the second support member 243 are perpendicularly arranged, the first support member 242 is arranged in the vertical direction, and the second support member 243 is arranged in the horizontal direction. In this way, the first support member 242 and the second support member 243 are arranged in an L shape. The structural forms of the first support member 242 and the second support member 243 are relatively regular, which can not only facilitate extrusion processing and forming, but also effectively and stably support the laminate 10.

[0074] Specifically, a glue application groove 25 is formed by enclosing the supporting portion 24, the clamping structure 22, and the frame body 21. The glue application groove 25 is located below the back surface 14 of the laminate 10, and the notch of the glue application groove 25 faces the back surface 14 of the laminate 10. With such a setting, during the assembly process of the photovoltaic module, the adhesive 251 can be first filled inside the glue application groove 25, and then the laminate 10 is installed on the supporting surface 241 of the photovoltaic frame 20 from top to bottom. The back surface 14 of the laminate 10 presses the adhesive 251 and overlaps with the supporting surface 241 and at the notch. The adhesive 251 inside the glue application groove 25 contacting the outer wall surface of the laminate 10 can achieve bonding and fixing of the laminate 10. It can be seen that the laminate 10 is not only clamped and fixed by the limiting member 23, but also bonded and fixed by the adhesive 251, so that it can be stably installed on the photovoltaic frame 20. In addition, since the glue application groove 25 is formed by enclosing the supporting portion 24, the clamping structure 22, and the frame body 21, the shape of the glue application groove 25 is, for example, U-shaped or approximately U-shaped, so as to play a role in limiting the adhesive 251 accommodated inside it on both the left and right sides. When the adhesive 251 is squeezed, it collides with the inner wall of the glue application groove 25 and moves inward. Compared with the groove body with unilateral limit, it can reduce the overflow of the adhesive 251 during the assembly process, thereby effectively reducing the cleaning difficulty and improving the production efficiency.

[0075] In one embodiment, a recess 244 is formed on the supporting surface 241. Optionally, the recess 244 is provided as one, or the recess 244 is provided as multiple, and all the recesses 244 are arranged in sequence along the direction away from the clamping structure 22. With such a setting, during the assembly process of the photovoltaic module, the adhesive 251 inside the glue application groove 25 can overflow into the recess 244 on the supporting surface 241 under the extrusion of the laminate 10. The recess 244 can increase the amount of the adhesive 251 on the supporting surface 241, thereby improving the bonding performance between the supporting surface 241 and the laminate 10. In addition, when the number of the recesses 244 is larger, the amount of the adhesive 251 on the supporting surface 241 is larger, thereby improving the bonding performance between the supporting surface 241 and the laminate 10.

[0076] The orthographic projection contour of the recess 244 on the supporting surface 241 can be set as a strip shape and extends along the longitudinal direction of the supporting portion 24. The orthographic projection contour of the recess 244 on the supporting surface 241 can also be set as a circular shape, a rectangular shape, a triangular shape, or other regular shapes and irregular shapes, and is, for example, arranged in a multi-point manner along the longitudinal direction of the supporting portion 24. In this way, each part of the supporting portion 24 along its longitudinal direction is adhesively connected to the laminate 10 through the adhesive 251, and the bonding performance of the laminate 10 on the photovoltaic frame 20 is stable and not easy to loosen.

[0077] It should be noted that the longitudinal direction in this embodiment refers to the direction perpendicular to the width direction W and perpendicular to the thickness direction of the laminate 10.

[0078] In one embodiment, the photovoltaic frame 20 further includes a barrier member 26. The barrier member 26 is disposed on a side of the support surface 241 facing away from the clamping structure 22. Optionally, the barrier member 26 extends along the longitudinal direction of the photovoltaic frame 20. Thus, during the assembly of the photovoltaic module, when the adhesive 251 inside the glue application groove 25 overflows onto the support surface 241 under the extrusion of the laminate 10, since the barrier member 26 abuts against the back surface 14 of the laminate 10 to form a closed space, it can effectively block the adhesive 251, prevent the adhesive 251 from overflowing, and thus effectively reduce the cleaning difficulty and improve the production efficiency.

[0079] Optionally, the barrier member 26 includes, but is not limited to, being configured as a barrier sheet, a barrier plate, or a barrier block. The side surface of the barrier member 26 that abuts against the back surface 14 of the laminate 10 is a plane, so that a good seal can be formed when abutting against the back surface 14 of the laminate 10, effectively preventing the adhesive 251 from overflowing.

[0080] In one embodiment, the barrier member 26 is a solid glue. Thus, the barrier member 26 has an adhesive property, can realize the bonding and fixing of the laminate 10 on the support surface 241, and enhance the installation stability of the laminate 10 on the photovoltaic frame 20. In addition, when the barrier member 26 is a solid glue, it can also block the overflowing adhesive 251, thereby effectively preventing the adhesive 251 inside the glue application groove 25 from overflowing.

[0081] Among them, the solid glue includes, but is not limited to, various types of solid glues such as silicone glue, thermosensitive glue, 3M glue, or PVB glue with a relatively high consistency. Specifically, the solid glue is preferably 3M glue, specifically, for example, 3M double-sided tape.

[0082] In addition, the adhesive 251 in this embodiment includes, but is not limited to, various types of liquid glues such as PU glue, TPU glue, PVB glue, EVA, or SGP glue. Thus, when the adhesive 251 is a liquid glue, during the assembly process, it can flow easily, so as to effectively realize the stable bonding and fixing of the back surface 14 of the laminate 10 on the photovoltaic frame 20.

[0083] The first clamping portion 222 and the second clamping portion 223 are each flexibly adjusted and set according to actual needs, and both include, but are not limited to, clamping plates, clamping blocks, or clamping strips, etc.

[0084] Please refer to Figures 4 to 6, the second clamping portion 223 is disposed on a side of the first clamping portion 222 facing away from the support portion 24. The distance between the portion of the first clamping portion 222 farthest from the support surface 241 (i.e., the top surface of the first clamping portion 222) and the support surface 241 is set as S2, and the distance between the portion of the second clamping portion 223 farthest from the support surface 241 (i.e., the top surface of the second clamping portion 223) and the support surface 241 is set as S3, and S3≥S2. With such a setting, before the step of installing the limiting member 23, the card slot 221 is equivalent to an overflow glue groove. When the adhesive 251 overflows, it enters the inside of the card slot 221 through the notch of the card slot 221 and is collected by the card slot 221, thereby preventing the adhesive 251 from overflowing, solving the problem of poor glue overflow, and relieving the cleaning pressure; in addition, since S3≥S2, that is, the height of the first clamping portion 222 close to the glue application groove 25 is relatively low, so that the adhesive 251 inside the glue application groove 25 is easy to overflow into the inside of the card slot 221. At the same time, the height of the second clamping portion 223 far from the glue application groove 25 is relatively high, and the second clamping portion 223 plays a blocking role, thereby preventing the adhesive 251 from overflowing, and further effectively reducing the cleaning difficulty and improving the production efficiency.

[0085] Exemplarily, S3 can be the same as S2. For details, please refer to Figure 8 or Figure 9 , the card slot 221 can also function as an overflow glue groove.

[0086] Of course, as some alternative solutions, S3 can also be less than S2. The card slot 221 can also function as an overflow glue groove.

[0087] In one embodiment, a first anti-slip portion 224 is provided on the inner wall of the card slot 221, and a second anti-slip portion 233 corresponding to the position of the first anti-slip portion 224 is provided on the outer wall of the clamping portion 231. The first anti-slip portion 224 and the second anti-slip portion 233 are in close contact. With such a setting, after the clamping portion 231 is inserted into the inside of the card slot 221, the first anti-slip portion 224 and the second anti-slip portion 233 are in close contact with each other, increasing the friction force, enabling the limiting member 23 to be stably installed on the clamping structure 22, effectively preventing the limiting member 23 from detaching from the clamping structure 22, and further improving the installation stability of the laminate 10 on the photovoltaic frame 20.

[0088] The first anti-slip portion 224 includes but is not limited to various forms of anti-slip structures such as saw teeth, anti-slip bumps or anti-slip patterns, etc., and can be flexibly adjusted and set according to actual needs, and will not be limited herein. Similarly, the second anti-slip portion 233 includes but is not limited to various forms of anti-slip structures such as saw teeth, anti-slip bumps or anti-slip patterns, etc., and can be flexibly adjusted and set according to actual needs, and will not be limited herein.

[0089] In a specific embodiment, the first anti-slip portion 224 is provided as serrations and is disposed on the first clamping portion 222, and the second anti-slip portion 233 is provided as serrations and is disposed on the side surface of the clamping portion 231 facing the first clamping portion 222.

[0090] Exemplarily, the extending direction of the clamping portion 231 is perpendicular to the support surface 241, and the first clamping portion 222 and the second clamping portion 223 are both perpendicular to the support surface 241, for example. Thus, when the limiting member 23 is clamped and installed in the card slot 221, it is only necessary to press the limiting member 23 in the vertical direction, which facilitates the installation of the limiting member 23 on the clamping structure 22, and the installation efficiency is relatively high.

[0091] Please refer to Figure 1 or Figure 2 Generally speaking, the end surface 13 of the front panel 11 is provided as an arc, and the end surface 13 of the back panel 12 is provided as an arc.

[0092] Please refer to Figures 4 to 6 Exemplarily, the limiting portion 232 is provided with a first limiting surface 2324 for abutting against and limiting the end surface 13 of the front panel 11 of the laminate 10, and the first limiting surface 2324 is provided as an arc surface. Taking full advantage of the fact that the end surface 13 of the front panel 11 is an arc, when the first limiting surface 2324 is provided as an arc surface, the shape of the first limiting surface 2324 matches the shape of the end surface 13 of the front panel 11, which can realize the pressing and fixing of the front panel 11 of the laminate 10, and maximally guarantees the mechanical load of the component, and finally enables the photovoltaic frame 20 without an A surface to be used normally.

[0093] Optionally, the arc angle of the first limiting surface 2324 includes but is not limited to 30°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, 90°, 100°, 120°, 150°, 170°, 180°, 190° or 200°, etc., and can be specifically adjusted and set flexibly according to actual needs. In this embodiment, the arc angle of the first limiting surface 2324 is specifically, for example, 80° to 100°, so that it is convenient to realize the abutting and limiting of the limiting member 23 against the end surface 13 of the front panel 11.

[0094] Please refer to Figures 4 to 6 Exemplarily, the clamping structure 22 is used to abut against the end surface 13 of the back panel 12 of the laminate 10 and is in limiting cooperation in the thickness direction of the laminate 10. Thus, under the limiting action of the limiting member 23 on the front panel 11 of the laminate 10, the clamping structure 22 abuts against the end surface 13 of the back panel 12 of the laminate 10, and simultaneously plays a limiting role on the end surface 13 of the back panel 12 of the laminate 10, enhancing the installation stability of the laminate 10 on the photovoltaic frame 20, so that the laminate 10 can be stably installed on the photovoltaic frame 20.

[0095] Specifically, the clamping structure 22 is provided with a second limiting surface 225 for abutting against and limiting the end surface 13 of the back plate 12 of the laminate 10, and the second limiting surface 225 is arranged as an arc surface. With such an arrangement, making full use of the arc characteristic of the end surface 13 of the back plate 12, when the second limiting surface 225 is arranged as an arc surface, the shape of the second limiting surface 225 matches that of the end surface 13 of the back plate 12, which can realize the pressing and fixing of the back plate 12 of the laminate 10, ensuring the mechanical load of the component to the greatest extent, and finally enabling the photovoltaic frame 20 without an A surface to be used normally.

[0096] In addition, since the shape of the second limiting surface 225 matches that of the end surface 13 of the back plate 12, not only can the sealing performance be improved to prevent the adhesive 251 from overflowing, but also in the step of assembling the laminate 10 downward onto the photovoltaic frame 20, when the adhesive 251 is extruded by the back plate 12 of the laminate 10, the second limiting surface 225 can guide the adhesive 251 to wrap the end surface 13 of the back plate 12, which is conducive to realizing the stable bonding and fixing of the laminate 10 on the photovoltaic frame 20.

[0097] Please refer to Figures 11 to 13 , the arc angle of the second limiting surface 225 can be specifically adjusted and set flexibly according to actual requirements. For example, as Figure 11 and Figure 12 shown, the arc angle of the second limiting surface 225 is 90°, Figure 11 shown, the second limiting surface 225 abuts and cooperates with the lower side part of the end surface 13 of the back plate 12, Figure 12 shown, the second limiting surface 225 abuts and cooperates with the upper side part of the end surface 13 of the back plate 12. For another example, as Figure 13 shown, the arc angle of the second limiting surface 225 can be 180°. Of course, optionally, the arc angle of the second limiting surface 225 can also be set to other angle sizes, including but not limited to 30°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, 90°, 100°, 120°, 150°, 170°, 180°, 190° or 200°, etc.

[0098] In this embodiment, the arc angle of the second limiting surface 225 is specifically, for example, 170° to 190°, and at the same time, the radius corresponding to the second limiting surface 225 is greater than the radius of the end surface 13 of the back plate 12, and the ratio size is, for example, 1.2 to 1.5. In this way, not only can the end surface 13 of the back plate 12 be clamped and fixed, but also the abutting and limiting operation of the clamping structure 22 on the end surface 13 of the back plate 12 can be facilitated.

[0099] Specifically, the second limiting surface 225 in this embodiment is formed on the side surface of the first clamping portion 222 facing the back plate 12.

[0100] The bottom shape of the card slot 221 can be flexibly adjusted and set according to actual needs, including but not limited to various regular shapes such as rectangles, triangles, squares, or other irregular shapes, and can be specifically adjusted and designed according to the space size or the strength of the photovoltaic frame 20, etc.

[0101] The structural form of the frame body 21 can be flexibly adjusted and designed according to actual needs, and will not be limited herein. By way of example, the frame body 21 includes a first side wall 211, a second side wall 212, a third side wall 213, and a fourth side wall 214. The first side wall 211, the second side wall 212, the third side wall 213, and the fourth side wall 214 are connected in sequence. A chamber is formed by enclosing the first side wall 211, the second side wall 212, the third side wall 213, and the fourth side wall 214. When there are multiple photovoltaic frames 20 and they are spliced and connected in sequence, corner codes can be inserted into the chamber to splice and combine multiple photovoltaic frames 20 together.

[0102] Among them, the clamping structure 22 and the supporting portion 24 are specifically arranged at intervals, for example, and are connected to the outer surface of the first side wall 211.

[0103] The design form of the outer surface of the second side wall 212 can be flexibly adjusted and set according to actual needs, and will not be limited herein. For example, the outer surface of the second side wall 212 can be flush with the surface of the second clamping portion 223 facing away from the first clamping portion 222, that is, as Figure 7a or Figure 8 shown; for another example, the outer surface of the second side wall 212 can also be designed to be retracted relative to the surface of the second clamping portion 223 facing away from the first clamping portion 222, that is, as Figure 9 or Figure 10 shown.

[0104] Please refer to Figures 3 to 6 In one embodiment, another embodiment of the present application provides a photovoltaic module, which includes the photovoltaic frame 20 of any of the above embodiments, and further includes a lamination 10. The lamination 10 overlaps on the support surface 241, and the limiting portion 232 abuts against the end surface 13 of the lamination 10 and is in limiting cooperation with the end surface 13 in the thickness direction of the lamination 10.

[0105] For the above-mentioned photovoltaic module, since it includes the above-mentioned photovoltaic frame 20, the technical effects are brought by the photovoltaic frame 20, and the beneficial effects include the beneficial effects of the photovoltaic frame 20, which will not be elaborated herein.

[0106] Among them, the limiting portion 232 is provided with a first limiting surface 2324 that abuts against and limits the end surface 13 of the front panel 11. Optionally, the first limiting surface 2324 matches the shape of the end surface 13 of the front panel 11. In this way, the first limiting surface 2324 can fully abut against the end surface 13 of the front panel 11, thereby effectively preventing the laminate 10 from disengaging upward, and enabling the laminate 10 to be stably installed on the photovoltaic frame 20.

[0107] Specifically, the end surface 13 of the front panel 11 is arc-shaped, and the first limiting surface 2324 is correspondingly provided as an arc surface. Of course, when the end surface 13 of the front panel 11 is set to other shapes, such as triangular, trapezoidal or other irregular shapes, the first limiting surface 2324 is correspondingly set to triangular, trapezoidal or other irregular shapes.

[0108] The clamping structure 22 is provided with a second limiting surface 225 that abuts against and limits the end surface 13 of the back panel 12. Optionally, the second limiting surface 225 matches the shape of the end surface 13 of the back panel 12. In this way, the second limiting surface 225 can fully abut against the end surface 13 of the back panel 12, thereby effectively preventing the laminate 10 from disengaging upward, and enabling the laminate 10 to be stably installed on the photovoltaic frame 20.

[0109] Specifically, the end surface 13 of the back panel 12 is arc-shaped, and the second limiting surface 225 is correspondingly provided as an arc surface. Of course, when the end surface 13 of the back panel 12 is set to other shapes, such as triangular, trapezoidal or other irregular shapes, the second limiting surface 225 is correspondingly set to triangular, trapezoidal or other irregular shapes.

[0110] In this embodiment, the outer contour shape and size of the back panel 12 can be the same as those of the front panel 11, as Figure 1 and Figure 7a shown. In this embodiment, the outer contour shape and size of the back panel 12 can also be larger than those of the front panel 11, as Figure 2 and Figure 8 shown. By way of example, please refer to Figure 8 , the back panel 12 is provided with a protruding portion 121 that protrudes outside the front panel 11, and the side of the protruding portion 121 facing the front panel 11 abuts against and is limited by the limiting portion 232. In this way, the limiting portion 232 can not only abut against and limit the end surface 13 of the front panel 11, but also abut against and limit the protruding portion 121 of the back panel 12, thereby enabling the laminate 10 to be firmly installed on the photovoltaic frame 20, effectively preventing the laminate 10 from disengaging upward, and enhancing the reliability.

[0111] In this embodiment, the side of the protrusion 121 facing the front panel 11 is flush with the top surface of the first clamping portion 222. The first abutting surface 2322 abuts not only the top surface of the first clamping portion 222, but also the side of the protrusion 121 facing the front panel 11.

[0112] In one embodiment, please refer to Figures 3 to 6 , the first limiting surface 2324 is specifically located on the side of the limiting portion 232 facing the laminate 10. Optionally, the side of the limiting portion 232 facing the laminate 10 also includes an avoidance surface 2325. The avoidance surface 2325 can avoid the end surface 13 of the front panel 11. In other words, the avoidance surface 2325 and the end surface 13 of the front panel 11 do not interfere with each other along the thickness direction of the laminate 10. The avoidance surface 2325 is connected to the first limiting surface 2324, and the avoidance surface 2325 is located at the lower part of the first limiting surface 2324. The side of the avoidance surface 2325 that is away from the first limiting surface 2324 is connected to the bottom surface of the limiting portion 232 (that is, the part of the limiting portion 232 facing the frame body 21). Specifically, the avoidance surface 2325 is connected to the first abutting surface 2322. The first limiting surface 2324 is connected to the guide surface 2321 at a side away from the avoiding surface 2325. With such a configuration, when the limiting member 23 is mounted on the clamping structure 22 from top to bottom, the avoiding surface 2325 of the limiting portion 232 can avoid the end surface 13 of the front panel 11, and there is no mutual interference with the end surface 13 of the front panel 11 along the thickness direction of the laminate 10, so that the limiting member 23 can be smoothly installed on the clamping structure 22, and at the same time, the first limiting surface 2324 presses the end surface 13 of the front panel 11 to limit the laminate 10, thereby ensuring the installation stability of the laminate 10 on the photovoltaic frame.

[0113] Optionally, the avoidance surface 2325 includes but is not limited to one or any combination of a plane, an arc surface and a fold line surface, as long as it can avoid the end surface 13 of the front panel 11 and prevent the avoidance surface 2325 and the end surface 13 of the front panel 11 from interfering with each other along the thickness direction of the laminate 10.

[0114] Based on the above examples, please refer to Figure 8 , the avoidance surface 2325 is, for example, set as a plane and perpendicular to the front of the laminate 10. The avoidance surface 2325 is also tangent to the first limiting surface 2324. In this way, on the one hand, for the laminate 10 whose width dimension of the back plate is larger than the width dimension of the front plate 11, while the first limiting surface 2324 is pressed against the end surface 13 of the front plate 11, the bottom surface of the limiting portion 232 simultaneously presses the protrusion 121 of the back plate 12, so that the laminate 10 can be stably set on the photovoltaic frame 20; on the other hand, the size of the limiting portion 232 is relatively large, so that the structural strength of the limiting portion 232 can be improved, ensuring that the laminate 10 is stably pressed.

[0115] In addition, please refer to Figures 3 to 6 , for the laminate 10 where the width dimension of the back plate 12 is equal to the width dimension of the front panel 11, while the first limiting surface 2324 presses against the end face 13 of the front panel 11, the bottom surface of the limiting portion 232 simultaneously presses against the top surface of the first clamping portion 222, thereby improving the installation stability of the laminate 10 on the photovoltaic frame 20.

[0116] As some alternative solutions, please compare and refer to Figure 7a and Figure 7b , the avoidance surface 2325 is not limited to being perpendicular to the front surface of the laminate 10, that is, not limited to being perpendicular to the bottom surface of the limiting portion 232, and can also be, for example, inclined with respect to the bottom surface of the limiting portion 232, and the bottom end of the avoidance surface 2325 extends in a direction away from the laminate 10. Optionally, the included angle formed by the avoidance surface 2325 and the top surface of the limiting portion 232 includes but is not limited to 30° to 90°, and the specific setting can be flexibly adjusted and set according to actual requirements.

[0117] Please refer to Figures 14 to 16 , Figures 14 to 16 , which respectively show three different state diagrams during the assembly work of the photovoltaic module of the first embodiment of the present application in sequence. In one embodiment, another embodiment of the present application provides an assembly method for a photovoltaic module adopting any of the above embodiments, and the assembly method includes the following steps:

[0118] Step S100: Place the laminate 10 in position on the support surface 241 of the photovoltaic frame 20;

[0119] Step S300: Clamp and install the limiting member 23 on the clamping structure 22, so that the limiting portion 232 abuts against the end face 13 of the laminate 10 and is in limiting cooperation with the end face 13 in the thickness direction of the laminate 10.

[0120] In the above assembly method of the photovoltaic module, when the laminate 10 is placed on the support surface 241, the laminate 10 is in a static state. While clamping and installing the limiting member 23 on the clamping structure 22 in the vertical direction, the limiting portion 232 abuts against the end face 13 of the laminate 10 and is in limiting cooperation with the end face 13 in the thickness direction of the laminate 10. In this way, not only can the photovoltaic module be quickly assembled together, but also the occurrence of component explosion defects during the assembly process of the laminate 10 can be reduced.

[0121] Specifically, before step S100, there is also step S10: Apply the adhesive 251 to the glue application groove 25 of the photovoltaic frame 20. In this way, the back surface 14 of the laminate 10 is adhesively fixed to the support surface 241 and the glue application groove 25, and can be stably installed on the photovoltaic frame 20.

[0122] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0123] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0124] In the present application, unless otherwise clearly specified and limited, if there are terms such as "mounted", "connected", "coupled", "fixed", etc., these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0125] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0126] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0127] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0128] The above-described embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
