[0045] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand 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.

[0046] It should be noted that, for the convenience of description and understanding, in this embodiment, "up" and "down" are referenced based on the state when the photovoltaic module is in normal use. The direction of the photovoltaic module facing the ground is down, and the direction away from the ground is up, and the vertical direction is the up-down direction.

[0047] It should be noted that, please refer to Figure 1 or Figure 2 , the laminated part 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. 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.

[0048] The laminate 10 specifically includes two types: double-glass laminate 10 and single-glass laminate 10. For the double-glass laminate 10, the backsheet 12 is specifically set as a light-transmitting plate, so that the light on the back 14 of the laminate 10 can also pass through the backsheet 12 and irradiate the cell, thereby improving the photoelectric efficiency. For the single-glass laminate 10, the backsheet 12 can correspondingly be set as an opaque plate.

[0049] Among them, please refer to Figure 1 , the size of the backsheet 12 can be the same as that of the front panel 11. After the backsheet 12 and the front panel 11 are laminated together, the outer peripheral contour (i.e., the end face 13) of the backsheet 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.

[0050] Of course, please refer to Figure 2 , the size of the backsheet 12 can also be larger than that of the front panel 11. For example, the width of the backsheet 12 is greater than the width of the front panel 11, or the length of the backsheet 12 is greater than the length of the front panel 11, or the width and length of the backsheet 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 backsheet 12 is larger than that of the front panel 11, there is a dislocation between the backsheet 12 and the front panel 11 in the thickness direction of the laminate 10. In other words, at least one side of the backsheet 12 protrudes into the area outside the front panel 11. Specifically, the backsheet 12 is provided with a protruding portion 121 that protrudes outside the front panel 11 in a direction parallel to the front face 15 of the laminate 10.

[0051] Refer to Figure 3 and Figure 6 , Figure 3 shows the structure diagram of the photovoltaic module of the first embodiment of the present application. Figure 4 shows Figure 3 the enlarged structure diagram at A. Figure 5 shows Figure 3 the structure diagram of the frame body 21 and the clamping structure 22 in the photovoltaic module shown. Figure 6 shows Figure 3 the structure diagram of the pressing member 23 in the photovoltaic module shown. Figure 5 shows the structure diagram of the photovoltaic module of the second embodiment of the present application. A photovoltaic frame 20 provided by 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. The supporting surface 241 is used to support the laminate 10. In other words, the assembly relationship of the laminate 10 on the photovoltaic frame 20 is that the back 14 of the laminate 10 (i.e., the side of the backsheet 12 facing away from the front panel 11, specifically as Figure 4The lower surface of the laminate 10 shown laps on the support surface 241. In this way, by supporting the edge of the back surface 14 of the laminate 10 on the support surface 241, stable support for the laminate 10 can be formed.

[0052] Exemplarily, the photovoltaic frame 20 includes a frame body 21 and a clamping structure 22. The clamping structure 22 is connected to the frame body 21.

[0053] 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 extruding aluminum. In this way, mass production of the clamping structure 22 and the frame body 21 can be achieved, and the combined structure of the clamping structure 22 and the frame body 21 is stable and reliable.

[0054] The clamping structure 22 is provided with a card slot 221 extending in the thickness direction of the laminate 10. Specifically, the clamping structure 22 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 the card slot 221.

[0055] Optionally, the first clamping portion 222 and the second clamping portion 223 can be flexibly adjusted and set according to actual needs, and all include but are not limited to clamping plates, clamping blocks or clamping strips, etc.

[0056] In addition, the photovoltaic frame 20 further includes a pressing member 23. The pressing member 23 includes a clamping portion 231. The clamping portion 231 is clamped and installed inside the card slot 221 in the thickness direction of the laminate 10, so that the pressing member 23 is clamped and connected to the clamping structure 22, that is, the pressing member 23 can be stably assembled to the photovoltaic frame 20. The pressing member 23 further includes a pressing portion 232, and the pressing portion 232 is connected to the clamping portion 231. Optionally, the pressing member 23 is integrally formed by extrusion, injection molding or processed by other methods, and can be specifically adjusted and set according to actual needs.

[0057] After the clamping portion 231 of the pressing member 23 is assembled into the inner portion of the card slot 221, the pressing portion 232 is, for example, located outside the card slot 221, that is, there is no need to be further pressed into the inner portion of the card slot 221. The pressing portion 232 is in abutting cooperation 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 pressing member 23, it is possible to correspondingly determine whether the installation of the pressing member 23 on the clamping structure 22 is in place according to whether the pressing portion 232 abuts and limits with the clamping structure 22, so as to determine whether the pressing member 23 presses the laminate 10; on the other hand, when the pressing portion 232 abuts against the portion of the clamping structure 22 facing away from the frame body 21, the clamping portion 231 can be firmly clamped and installed inside the card slot 221, and the installation stability of the pressing member 23 on the photovoltaic frame 20 is relatively high.

[0058] In this embodiment, the pressing portion 232 abuts against the portion of the second clamping portion 223 facing away from the frame body 21 (that is, the top surface of the second clamping portion 223). In other words, the width of the pressing portion 232 is greater than the width of the clamping portion 231. Specifically, the clamping portion 231 is, for example, connected to the middle portion of the pressing portion 232, so that the opposite ends of the pressing portion 232 along its width direction W (as Figure 6 shown) respectively protrude from the clamping portion 231.

[0059] The pressing portion 232 is also used to abut against the end face 13 of the laminate 10 and limit and cooperate with the end face 13 in the thickness direction of the laminate 10. Specifically, the pressing portion 232 can abut against the end face 13 of the front panel 11 and limit and cooperate with the end face 13 in the thickness direction of the laminate 10, and can also abut against the back plate 12 and limit and cooperate 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 plate 12 and limit and cooperate with the back plate 12 in the thickness direction of the laminate 10. In this way, the pressing portion 232 plays a role in limiting the laminate 10, preventing the laminate 10 from disengaging from the photovoltaic frame 20 in its thickness direction, and enabling the laminate 10 to be firmly installed on the photovoltaic frame 20.

[0060] A guiding surface 2321 is provided at the portion of the pressing member 23 facing away from the frame body 21. The distance between the guiding surface 2321 and the supporting surface 241 is set as S, and the thickness of the laminate 10 is set as D, and S≤D. In this way, the guiding surface 2321 can be flush with or slightly lower than the front surface 15 of the laminate 10, so as to facilitate guiding and draining the rainwater on the laminate 10 and facilitate removing the dust accumulated on the front surface 15 of the laminate 10.

[0061] Exemplarily, the guiding surface 2321 can be set as a flat surface, and for example, be flush with the front surface 15 of the laminate 10. In this way, it is also convenient to guide and drain the rainwater on the laminate 10, and to remove the dust accumulated on the front surface 15 of the laminate 10. In addition, a full-screen design can be achieved, which can be installed horizontally and vertically, and has a good effect of preventing dust accumulation. Additionally, on the side of the guiding surface 2321 facing away from the laminate 10, a chamfer can be provided, for example. Under the guidance of the chamfer, the rainwater is more likely to drain away, and it is not easy to hurt hands during the installation process.

[0062] 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 flat surface, it is also convenient to guide and drain the rainwater on the laminate 10, and to remove the dust accumulated on the front surface 15 of the laminate 10.

[0063] Exemplarily, the guiding surface 2321 can also be set as a combination form of a flat surface and an inclined surface or an arc. It can also play a role in guiding rainwater.

[0064] Exemplarily, the guiding surface 2321 can also be set as a surface with other regular or irregular shapes, which can be flexibly adjusted and set according to actual needs, and will not be limited here.

[0065] For the above-mentioned photovoltaic frame 20, on the one hand, the pressing member 23 is detachably installed inside the card slot 221 through the clamping portion 231 to achieve clamping cooperation with the clamping structure 22. At the same time, the pressing member 23 abuts against the end face 13 of the laminate 10 through the pressing portion 232 and is in limit cooperation with the end face 13 in the thickness direction of the laminate 10, so that the laminate 10 can be stably installed on the supporting surface 241, and the laminate 10 can be prevented from easily detaching from the photovoltaic frame 20 upward; on the other hand, the clamping portion 231 of the pressing member 23 is detachably installed inside the card slot 221 in the thickness direction of the laminate 10, that is, inserted into the card slot 221 from top to bottom. During the installation process, since the laminate 10 is already in a static state, in this way, the defect of the laminate 10 group frame explosion parts can be reduced; in addition, a guiding surface 2321 is provided on the side of the pressing member 23 facing away from the frame body 21. The guiding surface 2321 is disposed above the first clamping portion 222 and the second clamping portion 223, and because S≤D, the guiding surface 2321 will not protrude upward from the front surface 15 of the laminate 10, that is, the guiding surface 2321 is flush with or slightly lower than the front surface 15 of the laminate 10. Thus, the dust on the front surface 15 of the laminate 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 achieve dust prevention.

[0066] Please refer to Figure 1 or Figure 2, generally speaking, the end face 13 of the front panel 11 is set to be arc-shaped, and the end face 13 of the back panel 12 is set to be arc-shaped. Please refer to Figures 4 to 6 , for example, the pressing part 232 is provided with a limiting surface 2324 for abutting against and limiting the end face 13 of the front panel 11 of the laminate 10, and the limiting surface 2324 is set to be an arc-shaped surface. By making full use of the arc-shaped feature of the end face 13 of the front panel 11, when the limiting surface 2324 is set to be an arc-shaped surface, the limiting surface 2324 matches the shape of the end face 13 of the front panel 11, and the two are in full contact, which can realize the pressing and fixing of the front panel 11 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.

[0067] Optionally, the arc angle of the 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 flexibly adjusted and set according to actual needs. In this embodiment, the arc angle of the limiting surface 2324 is specifically, for example, 80° to 100°, so that it is convenient to realize the abutting and limiting of the pressing member 23 against the end face 13 of the front panel 11.

[0068] Optionally, when the back panel 12 is provided with a protruding part 121 protruding from the front panel 11, the bottom surface of the pressing member 23 also abuts against the top surface of the protruding part 121, playing a role in limiting the back panel 12 in the thickness direction thereof, preventing the laminate 10 from disengaging upward, and thus avoiding the reduction of the reliability of the photovoltaic module. In this way, the pressing member 23 not only presses the end face 13 of the front panel 11 through the limiting surface 2324, but also presses against the top surface of the protruding part 121, that is, the limiting surface 2324 and the bottom surface of the end of the pressing member 23 close to the back panel 12 jointly play a role in restricting the upward disengagement of the laminate 10, so that the laminate 10 is stably arranged on the photovoltaic frame 20.

[0069] Please refer to Figures 4 to 6, on the basis of the foregoing embodiments, the clamping portion 231 is connected to the middle portion of the pressing portion 232. The portion of the pressing portion 232 facing the frame body 21 is provided with a first abutting surface 2322 and a second abutting surface 2323. The first abutting surface 2322 and the second abutting surface 2323 are respectively located on opposite sides of the clamping portion 231. The second abutting surface 2323 abuts against the portion of the second clamping portion 223 facing away from the frame body 21, and the first abutting surface 2322 abuts against the top surface of the back plate 12 of the laminate 10. With such a setting, on the one hand, during the process of inserting the clamping portion 231 of the pressing member 23 into the card slot 221 from top to bottom, both opposite ends of the pressing portion 232 in its width direction W can be stressed, and the stress is relatively balanced, which is convenient for quickly and stably assembling the pressing member 23 onto the photovoltaic frame 20; on the other hand, a guiding surface 2321 is provided on the side of the pressing member 23 facing away from the frame body 21, and the guiding surface 2321 is disposed above the first clamping portion 222 and the second clamping portion 223 along the thickness direction of the laminate 10, so that it is convenient to better guide and drain rainwater outwards. In addition, the second abutting surface 2323 abuts against the portion of the second clamping portion 223 facing away from the frame body 21, and the first abutting surface 2322 abuts against the top surface of the back plate 12 of the laminate 10, which can improve the installation stability of the pressing member 23 on the clamping structure 22, and it is not easy to shake or fall off, and can improve the installation stability of the laminate 10 on the photovoltaic frame 20.

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

[0071] Please refer to again Figures 3 to 6, the limiting surface 2324 is specifically located on the side of the pressing part 232 facing the laminate 10. Optionally, the side of the pressing part 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 limiting surface 2324, and the avoidance surface 2325 is located at the lower part of the limiting surface 2324. The side of the avoidance surface 2325 facing away from the limiting surface 2324 is connected to the bottom surface of the pressing part 232. Specifically, the avoidance surface 2325 is connected to the first abutting surface 2322. The side of the limiting surface 2324 facing away from the avoidance surface 2325 is connected to the guide surface 2321. In this way, when the clamping piece 23 is installed on the snap-in structure 22 from top to bottom, the avoidance surface 2325 of the clamping 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 clamping piece 23 can be smoothly installed on the snap-in structure 22. At the same time, the 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 20.

[0072] 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.

[0073] Based on the above examples, please refer to Figures 3 to 6 , the avoidance surface 2325 is, for example, set as a plane and perpendicular to the front face 15 of the laminate 10. The avoidance surface 2325 is also tangent to the limiting surface 2324. In this way, on the one hand, for the laminate 10 whose width dimension of the back panel 12 is larger than the width dimension of the front panel 11, while the limiting surface 2324 is pressed against the end face 13 of the front panel 11, the bottom surface of the pressing part 232 simultaneously presses the protruding part 121 of the back panel 12, so that the laminate 10 can be stably set on the photovoltaic frame 20; on the other hand, the size of the pressing part 232 is relatively large, so that the structural strength of the pressing part 232 can be improved, ensuring that the laminate 10 is stably pressed.

[0074] For some alternatives, please see Figure 8a and Figure 8b, The avoidance surface 2325 is not limited to being perpendicular to the front surface 15 of the laminate 10, that is, not limited to being perpendicular to the bottom surface of the pressing portion 232. It can also be, for example, inclined with respect to the bottom surface of the pressing 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 pressing 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.

[0075] Please refer to Figure 3 and Figure 4 , On the basis of the foregoing embodiments, the photovoltaic frame 20 further includes a support portion 24. The support portion 24 is connected to the frame body 21, and the support surface 241 is disposed on the 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 under the support of the support portion 24, the installation stability can be ensured.

[0076] 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.

[0077] 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 independently and flexibly adjusted and set according to their respective actual requirements, 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 included angle with each other. The included angle formed by the first support member 242 and the second support member 243 includes but is 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.

[0078] Please refer to Figure 3 and Figure 4, 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 on the supporting surface 241 and at the notch. The adhesive 251 inside the glue application groove 25 contacts the outer wall surface of the laminate 10 to achieve bonding and fixing of the laminate 10. It can be seen that the laminate 10 is not only clamped and fixed by the pressing 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, the glue application groove 25 is formed by enclosing the supporting portion 24, the clamping structure 22, and the frame body 21. Optionally, the shape of the glue application groove 25 is, for example, U-shaped, jar mouth-shaped, trapezoidal or other irregular shapes, so as to play a role of limiting the adhesive 251 on both 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 single-sided limitation, it can reduce the overflow of the adhesive 251 during the assembly process, thereby effectively reducing the cleaning difficulty and improving the production efficiency.

[0079] Please refer to Figures 3 to 6 , the second clamping portion 223 is arranged on the side of the first clamping portion 222 facing away from the supporting portion 24. The top surface position of the second clamping portion 223 is higher than the top surface position of the first clamping portion 222. With such a setting, before the step of installing the pressing member 23, the card slot 221 is equivalent to an overflow slot. 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 overflow of glue, and relieving the cleaning pressure; in addition, since the top surface position of the second clamping portion 223 is higher than the top surface position of the first clamping portion 222, that is, the height of the top surface 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, and 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.

[0080] Exemplarily, the top surface position of the second clamping portion 223 can also be flush with the top surface position of the first clamping portion 222, and the card slot 221 can also play the role of an overflow slot.

[0081] Of course, as some optional solutions, the height of the top surface position of the second clamping portion 223 can also be lower than the height of the top surface position of the first clamping portion 222. The card slot 221 can also play the role of an overflow slot.

[0082] In some embodiments, the notch of the glue overflow groove is located at the upper part, and the shape of the notch includes, but is not limited to, a rectangle or an irregular shape. During the lamination process of the photovoltaic module, the adhesive 251 flows into the bottom of the glue overflow groove through the notch of the glue overflow groove. The shape of the bottom of the glue overflow groove includes, but is not limited to, various regular shapes such as a rectangle, a triangle, a square, or other irregular shapes, and can be flexibly adjusted and designed according to the space size or the strength of the photovoltaic frame 20, etc.

[0083] Please refer to Figures 3 to 6 , in some embodiments, the pressing member 23 further includes a guiding portion 234. The guiding portion 234 is connected to the side of the pressing portion 232 facing the frame body 21. The guiding portion 234 is located on the side of the clamping portion 231 facing the laminate 10, and the guiding portion 234 is disposed adjacent to the end face 13 of the back plate 12 of the laminate 10. Thus, during the lamination process of the laminate 10, the adhesive 251 inside the glue application groove 25 is guided by the guiding portion 234, which is beneficial to flow towards the end face 13 of the back plate 12, thereby wrapping the end face 13 of the back plate 12, and can enhance the sealing performance and the bonding stability.

[0084] Optionally, the guiding portion 234 can either have a gap with the clamping portion 231 or be arranged without a gap with the clamping portion 231, that is, the guiding portion 234 and the clamping portion 231 are connected to form an integral structure. How to set it specifically is not limited herein.

[0085] Please refer to Figures 3 to 6 , on the basis of the foregoing embodiments, the guiding portion 234 is located above the first clamping portion 222, and a gap space 235 is provided between the guiding portion 234 and the first clamping portion 222. Thus, on the one hand, based on the fact that the top surface position of the first clamping portion 222 is lower than the top surface position of the second clamping portion 223, when the second clamping portion 223 abuts against the pressing portion 232, there is still a space between the top surface of the first clamping portion 222 and the bottom surface of the pressing portion 232, and this space is used to set the guiding portion 234, making the overall structural layout compact and the volume size smaller; on the other hand, a gap space 235 is provided between the guiding portion 234 and the first clamping portion 222. During the lamination process of the photovoltaic module, the adhesive 251 inside the glue application groove 25 can overflow into the card slot 221 through the gap space 235. Furthermore, even if there is glue overflow, the residual glue will first enter the card slot 221 through the gap space 235, which can greatly improve the problem of glue overflow during the manufacturing process and relieve the cleaning pressure.

[0086] Please compare and refer to Figure 3 and Figure 7 or refer to Figure 10 with Figure 11, in some embodiments, the length of the clamping portion 231 can be flexibly adjusted and set according to actual requirements, as long as the clamping portion 231 can be inserted into the card slot 221 and can be clamped and fixed with the clamping structure 22. When the length of the clamping portion 231 is longer, the depth of the clamping portion 231 extending into the card slot 221 is greater, and the clamping stability is enhanced, but the unoccupied space inside the card slot 221 is correspondingly reduced, and the amount of the adhesive 251 that can be accommodated is correspondingly reduced; conversely, when the length of the clamping portion 231 is shorter, the depth of the clamping portion 231 extending into the card slot 221 is smaller, and the clamping stability is weakened, but the unoccupied space inside the card slot 221 is correspondingly increased, and the amount of the adhesive 251 that can be accommodated is correspondingly increased. In this embodiment, by flexibly adjusting the length of the clamping portion 231, the overflow glue effect and the connection stability with the clamping structure 22 can be correspondingly improved.

[0087] Please refer to Figure 3 and Figure 7 or refer to Figure 10 and Figure 11 , in some embodiments, the length of the guiding portion 234 can be flexibly adjusted and set according to actual requirements. When the length of the guiding portion 234 is adjusted, the amount of the adhesive 251 wrapped around the end face 13 of the back plate 12 can be correspondingly adjusted, and the size of the spacing space 235 can be adjusted, thereby adjusting the amount of the adhesive 251 overflowing into the card slot 221. Specifically, when the length of the guiding portion 234 is longer, the amount of the adhesive 251 wrapped around the end face 13 of the back plate 12 can be increased, so as to improve the sealing performance and connection stability. However, since the spacing space 235 becomes smaller, the amount of the adhesive 251 overflowing into the card slot 221 becomes smaller, thereby increasing the risk of glue overflow; conversely, when the length of the guiding portion 234 is shorter, the amount of the adhesive 251 wrapped around the end face 13 of the back plate 12 is correspondingly reduced, but since the spacing space 235 becomes larger, the amount of the adhesive 251 overflowing into the card slot 221 increases, and the risk of glue overflow is greatly reduced.

[0088] Optionally, the ratio of the length of the guiding portion 234 to the thickness of the back plate 12 includes but is not limited to 50% to 100%, specifically for example 50%, 70%, 75%, 80%, 90% or 100%. Thus, when the ratio is less than 50%, the wrapping effect of the adhesive 251 on the end face 13 of the back plate 12 is poor, and the sealing performance and connection stability are reduced; conversely, when the ratio is greater than 100%, the spacing space 235 is smaller, the amount of the adhesive 251 overflowing into the card slot 221 is smaller, and the risk of glue overflow is increased.

[0089] Please refer to Figure 3 and Figure 4, for example, the guiding portion 234 abuts against the end face 13 of the back plate 12 and is in a limiting fit in a direction parallel to the front face 15 of the laminate 10. In this way, the guiding portion 234 not only guides the adhesive 251, but also plays a limiting role on the laminate 10 by abutting against the end face 13 of the back plate 12, which can improve the installation stability of the laminate 10 on the photovoltaic frame 20.

[0090] In some alternative solutions, please refer to Figure 8a and Figure 12 , the guiding portion 234 in the above embodiment can be omitted. Specifically, the portion of the pressing portion 232 other than the clamping portion 231 on the bottom surface is, for example, set as a plane or a surface with an irregular shape.

[0091] In some alternative solutions, please refer to Figure 9 and Figure 13 , when the sizes of the front plate 11 and the back plate 12 are the same, in the case where the guiding portion 234 is provided, the side of the guiding portion 234 facing the end face 13 of the back plate 12 is flush with the side of the pressing portion 232 facing the laminate 10.

[0092] In one embodiment, please refer to Figures 3 to 6 , the supporting surface 241 is formed with a recess 244. Optionally, the recess 244 is provided as one, or the recess 244 is provided as a plurality, and all the recesses 244 are arranged in sequence in a direction away from the clamping structure 22. With such a setting, during the assembly 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 more, thereby improving the bonding performance between the supporting surface 241 and the laminate 10.

[0093] The orthographic projection profile 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 profile 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.

[0094] 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.

[0095] Please refer to Figures 3 to 6 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.

[0096] 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 flat surface, so that a good sealing property can be formed when abutting against the back surface 14 of the laminate 10, effectively preventing the adhesive 251 from overflowing.

[0097] 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.

[0098] Among them, the solid glue includes, but is not limited to, various types of solid glues such as silicone glue, thermal sensitive 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.

[0099] 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.

[0100] 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 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 pressing member 23 to be stably installed on the clamping structure 22, effectively preventing the pressing member 23 from detaching from the clamping structure 22, and further improving the installation stability of the laminate 10 on the photovoltaic frame 20.

[0101] The first anti-slip portion 224 includes, but is not limited to, anti-slip structures in various forms such as serrations, anti-slip bumps, anchor points, or anti-slip patterns, etc. Specifically, it 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, anti-slip structures in various forms such as serrations, anti-slip bumps, anchor points, or anti-slip patterns, etc. Specifically, it can be flexibly adjusted and set according to actual needs and will not be limited herein.

[0102] In a specific embodiment, the first anti-slip portion 224 is set as serrations and is disposed on the first clamping portion 222, and the second anti-slip portion 233 is set as serrations and is disposed on the side of the clamping portion 231 facing the first clamping portion 222.

[0103] Exemplarily, the extending direction of the clamping portion 231 is perpendicular to the support surface 241, and both the first clamping portion 222 and the second clamping portion 223 are, for example, perpendicular to the support surface 241. Thus, when the pressing member 23 is clamped and installed in the card slot 221, it is only necessary to press the pressing member 23 in the vertical direction, which can facilitate the installation of the pressing member 23 on the clamping structure 22 and has a high installation efficiency.

[0104] Exemplarily, not only is the guiding surface 2321 flush with or slightly lower than the front surface 15 of the laminate 10, but also the side of the pressing portion 232 facing away from the laminate 10 (such as Figure 4 the left side as shown) is flush with the side of the clamping structure 22 facing away from the laminate 10 (such as Figure 4 the left side as shown). Thus, the dust on the front surface 15 of the laminate 10 is easily washed away by rainwater, and the dust on the side surfaces of the pressing portion 232 and the clamping structure 22 is also easily washed away by rainwater, realizing self-cleaning of the photovoltaic module, which can reduce the operation and maintenance cost and effectively achieve anti-dust accumulation.

[0105] The structural form of the frame body 21 can be flexibly adjusted and designed according to actual needs and will not be limited herein. Exemplarily, please refer to Figure 3 、 Figures 7 to 9 , 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 sequentially spliced and connected, the chamber can insert corner codes to realize the splicing and combination of multiple photovoltaic frames 20 together.

[0106] Exemplarily, please refer to Figures 10 to 13 , the frame body 21 can also be set in the form of a guide rail, specifically, for example, an opening is provided on the third side wall 213. Of course, the frame body 21 can also be set in other irregular shapes, and can be specifically flexibly adjusted and set according to actual needs.

[0107] 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.

[0108] 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 7 or Figure 9 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 8a or Figure 12 shown.

[0109] 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 laminate 10. The laminate 10 is lapped on the supporting surface 241, and the pressing portion 232 abuts against the end surface 13 of the laminate 10 and is in limit fit with the end surface 13 in the thickness direction of the laminate 10.

[0110] 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.

[0111] Among them, the pressing portion 232 is provided with a limiting surface 2324 that abuts against and limits the end surface 13 of the front panel 11. Optionally, the limiting surface 2324 matches the shape of the end surface 13 of the front panel 11. In this way, the limiting surface 2324 can fully abut against the end surface 13 of the front panel 11, so as to effectively prevent the laminate 10 from disengaging upward, and enable the laminate 10 to be stably installed on the photovoltaic frame 20.

[0112] Specifically, the end surface 13 of the front panel 11 is arc-shaped, and the limiting surface 2324 is correspondingly set 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 limiting surface 2324 is correspondingly set as triangular, trapezoidal or other irregular shapes.

[0113] 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, such as Figure 1 and Figure 8a , Figure 9 , Figure 12 and Figure 13 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, such asFigure 2 , Figure 3 , Figure 7 , Figure 8a , Figure 10 and Figure 11 as shown. By way of example, please refer to Figures 2 to 4 . The back plate 12 is provided with a protruding portion 121 that protrudes outside the front plate 11 in a direction parallel to the front surface 15 of the laminate 10. One side of the protruding portion 121 facing the front plate 11 abuts and limits the position with the pressing portion 232. In this way, the pressing portion 232 can not only abut and limit the position of the end surface 13 of the front plate 11, but also abut and limit the position of the protruding portion 121 of the back plate 12, so that the laminate 10 can be stably installed on the photovoltaic frame 20, effectively preventing the laminate 10 from disengaging upward, and enhancing the reliability.

[0114] Please refer to Figures 14 to 16 , Figures 14 to 16 which respectively and sequentially show three different state diagrams during the assembly work of the photovoltaic module of the first embodiment of the present application. In one embodiment, another embodiment of the present application provides an assembly method of a photovoltaic module adopting any one of the above embodiments. The assembly method includes the following steps:

[0115] Step S100: Place the laminate 10 in position on the support surface 241 of the photovoltaic frame 20;

[0116] Step S200: Snap and install the pressing member 23 on the snap structure 22, so that the pressing portion 232 abuts against the end surface 13 of the laminate 10 and is in limit fit with the end surface 13 in the thickness direction of the laminate 10.

[0117] 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 the pressing member 23 is snap - installed on the snap structure 22 in the vertical direction, the pressing portion 232 abuts against the end surface 13 of the laminate 10 and is in limit fit with the end surface 13 in the thickness direction of the laminate 10. In this way, not only can the photovoltaic modules be quickly assembled together, but also the occurrence of defective parts during the assembly process of the laminate 10 can be reduced.

[0118] Specifically, before step S100, there is also step S10: Apply the adhesive 251 to the glue - applying 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 - applying groove 25, and it can be stably installed on the photovoltaic frame 20.

[0119] 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. These are 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 thus should not be construed as a limitation on the present application.

[0120] 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 such feature. 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 and clearly defined.

[0121] In the present application, unless otherwise clearly specified and limited, if there are terms such as "mounted", "connected", "connected to", "fixed", etc., these terms should be understood in a broad sense.
