Description

Technical Field

[0002] In the photovoltaic field, when installing photovoltaic modules, they are generally installed at an inclination of 5° to 45° facing south. In some outdoor areas with large dust, dust is likely to accumulate on the front of the laminates of photovoltaic modules. The accumulated dust will block sunlight, resulting in a decrease in the power generation efficiency of the photovoltaic modules. Seriously, it will also exacerbate the surface wear of the laminates and shorten the equipment life. According to statistics, about 80% of industrial and commercial scenarios are troubled by dust accumulation on photovoltaic modules. When the mud belt formed by dust accumulation reaches 90 mm, it can cause a power loss of about 23%. Summary of the Invention

[0052] 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 with reference to the accompanying drawings. Many specific details are set forth in the following description in order 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.

[0053] 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 in which the photovoltaic module faces the ground is down, and the direction away from the ground is up, and the vertical direction is the up and down direction.

[0054] 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 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 a light-transmitting plate or an opaque plate, which is not limited herein.

[0055] The laminate 10 specifically includes two types: double-glass laminate and single-glass laminate. For the double-glass laminate 10, the backsheet 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 backsheet 12 and irradiate the solar cell, thereby improving the photoelectric efficiency. For the single-glass laminate, the backsheet 12 can be correspondingly set as an opaque plate.

[0056] Among them, please refer to Figure 1 , the size of the backsheet 12 can be the same as that of the front panel 11. In this way, after the backsheet 12 and the front panel 11 are laminated together, the outer peripheral contour of the backsheet 12 and the outer peripheral contour of the front panel 11 are aligned with each other in the thickness direction of the laminate 10. Among them, the outer peripheral contours of the backsheet 12 and the front panel 11 are hereinafter referred to as the end faces 13 of the laminate 10.

[0057] 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.

[0058] Refer to Figure 3 and Figure 6a , 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 the structural diagram of the photovoltaic module of the second embodiment of the present application. Figure 6a shows Figure 5 the enlarged structural diagram at B. Figure 5 and Figure 3 The main difference lies in the different types of the laminate 10.

[0059] A photovoltaic frame 20 provided in an embodiment of the present application, the photovoltaic frame 20 is used to install the laminate 10, and the photovoltaic frame 20 is provided with a support 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 backsheet 12 facing away from the front panel 11) is lapped on the support surface 241. In this way, by supporting the edge of the back surface 14 of the laminate 10 through the support surface 241, a stable support can be formed for the laminate 10.

[0060] Exemplarily, the photovoltaic frame 20 includes a frame body 21 and a clamping structure 22 connected to the frame body 21. Optionally, the clamping structure 22 and the frame body 21 are integrally formed by extrusion. Specifically, the clamping structure 22 and the frame body 21 are integrally formed by extrusion of 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.

[0061] In addition, the photovoltaic frame 20 further includes a clamping member 23 that is in clamping cooperation with the clamping structure 22. The clamping member 23 and / or the clamping structure 22 are used to abut against the end face 13 of the laminate 10 and are in limit cooperation with the end face 13 in the thickness direction of the laminate 10.

[0062] Wherein, the clamping member 23 includes a clamping portion 231 and a limiting portion 232 connected to the clamping portion 231. The clamping structure 22 is formed with a clamping groove 221, and the clamping portion 231 is clamped and installed inside the clamping groove 221. The limiting portion 232 is used to abut against the end face 13 of the laminate 10 and is in limit cooperation with the end face 13 in the thickness direction of the laminate 10. Specifically, the limiting portion 232 can either abut against and limit the end face 13 of the front panel 11, or abut against and limit the end face 13 of the back panel 12, or abut against and limit both the end face 13 of the front panel 11 and the end face 13 of the back panel 12.

[0063] Of course, as some alternative solutions, the clamping member 23 can also be, for example, abutted and limited against the side of the back panel 12 facing the front panel 11. At the same time, the clamping structure 22 abuts against the end face 13 of the laminate 10 and is limited in the thickness direction, specifically abutting against the end face 13 of the back panel 12 and being in limit cooperation in the thickness direction.

[0064] Please refer to Figure 5 and Figure 6a , the distance between the surface of the clamping member 23 facing away from and farthest from the support surface 241 and the support surface 241 is set as S1, the distance between the surface of the clamping structure 22 facing away from and farthest from the support surface 241 and the support surface 241 is set as S2, the thickness of the laminate 10 is set as D, S1 ≤ D, S2 ≤ D.

[0065] Optionally, since the clamping member 23 is closer to the laminate 10 than the clamping structure 22, S2 ≤ S1, and a better dust prevention effect can be achieved.

[0066] For the above-mentioned photovoltaic frame 20, on the one hand, the clamping member 23 is clamped and installed inside the clamping groove 221 through the clamping portion 231 to achieve clamping cooperation with the clamping structure 22. At the same time, the clamping member 23 abuts against the end face 13 of the lamination member 10 through the limiting portion 232 and is in limiting cooperation with the end face 13 in the thickness direction of the lamination member 10, so that the lamination member 10 can be stably installed on the support surface 241 to prevent the lamination member 10 from disengaging upward from the photovoltaic frame 20. On the other hand, since S1≤D and S2≤D, neither the clamping member 23 nor the clamping structure 22 protrudes upward from the front face 15 of the lamination member 10. Thus, the dust on the front face 15 of the lamination 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.

[0067] On the basis of the foregoing embodiment, the photovoltaic frame 20 further includes a support portion 24. The support portion 24 is provided at one end of the frame main body 21 where the clamping structure 22 is formed, and the support surface 241 is provided on the side of the support portion 24 facing away from the frame main body 21. In this way, the back face 14 of the lamination member 10 is lapped on the support portion 24 and supported on the support surface 241, so that under the support of the support portion 24, the installation stability of the lamination member can be ensured.

[0068] Exemplarily, the support portion 24, the frame main body 21 and the clamping structure 22 are integrally formed by extrusion. Specifically, the support portion 24, the frame main body 21 and the clamping structure 22 are integrally formed by extrusion using, for example, aluminum.

[0069] 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 main 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 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 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 lamination member 10.

[0070] Specifically, a glue application groove 25 is formed by enclosing the supporting part 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 in 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 fixed by clamping through the clamping member 23, but also fixed by bonding through 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 part 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 therein on both the left and right sides. When the adhesive 251 is pressed, it collides with the inner wall of the glue application groove 25 and moves inward. Compared with the groove body with unilateral limit, the overflow of the adhesive 251 during the assembly process can be reduced, so that the cleaning difficulty can be effectively reduced and the production efficiency can be improved.

[0071] 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, so as to improve 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, so as to improve the bonding performance between the supporting surface 241 and the laminate 10.

[0072] 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 part 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 part 24. In this way, each part of the supporting part 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.

[0073] In one embodiment, the photovoltaic frame 20 further includes a barrier 26 extending along its longitudinal direction. The barrier 26 is disposed on the side of the support surface 241 away from the clamping structure 22. In this way, during the assembly process of the photovoltaic module, when the adhesive 251 in the adhesive groove 25 can overflow onto the support surface 241 under the pressure of the laminate 10, the barrier 26 abuts against the back surface 14 of the laminate 10 to form a closed space, thereby effectively blocking the adhesive 251 and preventing the adhesive 251 from overflowing, thereby effectively reducing the difficulty of cleaning and improving production efficiency.

[0074] Optionally, the barrier 26 includes but is not limited to a barrier sheet, a barrier plate or a barrier block. The side of the barrier 26 abutting 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.

[0075] In one embodiment, the barrier 26 is solid glue. In this way, the barrier 26 has adhesive properties, and can achieve the laminate 10 being bonded and fixed on the support surface 241, and the installation stability of the laminate 10 on the photovoltaic frame 20 is enhanced. In addition, when the barrier 26 is solid glue, it can also block the overflowing adhesive 251, thereby effectively preventing the adhesive 251 inside the adhesive groove 25 from overflowing.

[0076] The solid glue includes but is not limited to various types of solid glue such as high-viscosity silicone glue, thermal glue, 3M glue or PVB glue. Specifically, the solid glue preferably uses 3M glue, such as 3M double-sided tape.

[0077] In addition, the adhesive 251 in this embodiment includes but is not limited to various types of liquid adhesives such as PU adhesive, TPU adhesive, PVB adhesive, EVA or SGP adhesive, etc. Thus, when the adhesive 251 is liquid adhesive, it can flow easily during the assembly process, thereby effectively achieving the stable bonding and fixing of the back side 14 of the laminate 10 to the photovoltaic frame 20.

[0078] See also Figure 5 and Figure 6a, in one embodiment, the snap-fit structure 22 includes a first partition wall 222 and a second partition wall 223. The first partition wall 222 and the second partition wall 223 are spaced apart on the frame body 21, and a card slot 221 is defined therebetween. Specifically, the second partition wall 223 is disposed on a side of the first partition wall 222 facing away from the support portion 24; the distance between the portion of the second partition wall 223 farthest from the support surface 241 and the support surface 241 is set as S2, and the distance between the portion of the first partition wall 222 farthest from the support surface 241 and the support surface 241 is set as S3, and S2≥S3. With such a setting, on the one hand, the clamping portion 231 is snap-fitted inside the card slot 221 defined between the first partition wall 222 and the second partition wall 223, so that the snap-fit member 23 can be stably connected to the snap-fit structure 22; on the other hand, before the step of installing the snap-fit member 23, the card slot 221 is equivalent to an overflow slot, and 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 the adhesive, and alleviating the cleaning pressure; in addition, since S2≥S3, the adhesive 251 inside the glue application groove 25 is facilitated to overflow into the inside of the card slot 221, and at the same time, the second partition wall 223 plays a blocking role, thereby preventing the adhesive 251 from overflowing, and further effectively reducing the cleaning difficulty and improving the production efficiency.

[0079] Of course, as some alternative solutions, S2 can also be less than S3. The card slot 221 can also function as an overflow slot.

[0080] Please refer to Figure 5 and Figure 6a , by way of example, the side surface of the limiting portion 232 facing the second partition wall 223 and the side surface of the clamping portion 231 facing the second partition wall 223 are flush with each other. With such a setting, the side surface of the snap-fit member 23 facing the second partition wall 223 is specifically set as a plane, so that the snap-fit member 23 can be inserted into the inside of the card slot 221 from top to bottom.

[0081] By way of example, the side of the limiting portion 232 facing away from the second partition wall 223 protrudes from the side of the clamping portion 231 facing the second partition wall 223. Thus, the side of the limiting portion 232 facing away from the second partition wall 223 can protrude towards the end surface 13 of the laminate 10, so that the side of the limiting portion 232 facing away from the second partition wall 223 can abut against the end surface 13 of the laminate 10 and be in limit cooperation with the end surface 13 in the thickness direction of the laminate 10.

[0082] By way of example, the limiting portion 232 overlaps the top of the first partition wall 222. Thus, when the snap-fit member 23 is installed in place on the snap-fit structure 22, the first partition wall 222 abuts against and limits the limiting portion 232, so that the snap-fit member 23 is stably snap-fitted on the snap-fit structure 22, and the installation stability of the laminate 10 on the photovoltaic frame 20 can be improved.

[0083] Please refer to Figure 6a , in some embodiments, a first guiding surface 2321 is provided on a side of the limiting portion 232 facing away from the first partition wall 222, and a second guiding surface 2231 is provided at a portion of the second partition wall 223 facing away from the frame body 21. Thus, by flexibly adjusting and setting the height positions and shapes of the first guiding surface 2321 and the second guiding surface 2231 relative to the supporting surface 241 respectively, the dust accumulated on the front surface 15 of the laminate 10 can be smoothly discharged outward through the first guiding surface 2321 and the second guiding surface 2231 under the flushing of rainwater. Furthermore, the photovoltaic module has the function of preventing dust accumulation, thereby improving the photoelectric efficiency and service life.

[0084] Please refer to Figure 4 , Figure 6a or Figure 11 , exemplarily, both the first guiding surface 2321 and the second guiding surface 2231 are set as flat surfaces and are arranged flush with each other, and both the first guiding surface 2321 and the second guiding surface 2231 are parallel to the supporting surface 241. In addition, the first guiding surface 2321 and the second guiding surface 2231 can also be arranged flush with the front surface 15 of the laminate 10, or slightly lower than the front surface 15 of the laminate 10. Thus, it is beneficial for the dust accumulated on the front surface 15 of the laminate 10 to be smoothly discharged outward through the first guiding surface 2321 and the second guiding surface 2231 under the flushing of rainwater. In addition, a full-screen design can be achieved, it can be installed horizontally or vertically, and the dust prevention effect is better.

[0085] Please refer to Figure 9 , exemplarily, the distance between the second guiding surface 2231 and the supporting surface 241 is smaller than the distance between the first guiding surface 2321 and the supporting surface 241. Specifically, the second guiding surface 2231 can also be arranged flush with the front surface 15 of the laminate 10, or slightly lower than the front surface 15 of the laminate 10. In this embodiment, the second guiding surface 2231 is set to be arranged flush with the front surface 15 of the laminate 10. Thus, it is also beneficial for the dust accumulated on the front surface 15 of the laminate 10 to be smoothly discharged outward through the first guiding surface 2321 and the second guiding surface 2231 under the flushing of rainwater. In addition, a full-screen design can be achieved, it can be installed horizontally or vertically, and the dust prevention effect is better.

[0086] Please continue to refer to Figure 9 , in order to better guide rainwater, a chamfer is formed, for example, on a side of the first guiding surface 2321 facing away from the supporting surface 241, and a chamfer is formed, for example, on a side of the second guiding surface 2231 facing away from the supporting surface 241. Thus, the rainwater is more easily drained under the guidance of the chamfer, and it is not easy to hurt hands during the installation process.

[0087] Please refer to Figure 10, for example, the first guiding surface 2321 includes a first connecting surface 2322 and a second connecting surface 2323. The first connecting surface 2322 is connected to the second connecting surface 2323. The first connecting surface 2322 is parallel to the supporting surface 241. The second connecting surface 2323 is closer to the second guiding surface 2231 than the first connecting surface 2322. The side of the second connecting surface 2323 facing away from the first connecting surface 2322 extends to the second guiding surface 2231. The distances between the second connecting surface 2323 and the second guiding surface 2231 and the supporting surface 241 show a decreasing trend in the direction away from the first connecting surface 2322. In this way, on the one hand, the first guiding surface 2321 and the second guiding surface 2231 play a good guiding role for rainwater and have a good dust-proof effect; on the other hand, the first connecting surface 2322 can also be flush with the front surface 15 of the laminate 10, or slightly lower than the front surface 15 of the laminate 10. The first connecting surface 2322 can ensure that the thickness of the contact part between the limiting part 232 and the end face 13 is relatively large, so as to ensure that the laminate 10 is stably limited on the photovoltaic frame 20.

[0088] Please continue to refer to Figure 10 , specifically, both the second connecting surface 2323 and the second guiding surface 2231 are arranged at an angle with the supporting surface 241. More specifically, the angles formed by the second connecting surface 2323 and the second guiding surface 2231 with the supporting surface 241 are of the same size.

[0089] 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 clamping member 23 to be stably installed on the clamping structure 22, effectively preventing the clamping member 23 from detaching from the clamping structure 22, and further improving the installation stability of the laminate 10 on the photovoltaic frame 20.

[0090] 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 here. 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 here.

[0091] In a specific embodiment, the first anti-slip portion 224 is set as saw teeth and is provided on the first partition wall 222, and the second anti-slip portion 233 is set as saw teeth and is provided on the side surface of the clamping portion 231 facing the first partition wall 222.

[0092] For example, the extending direction of the clamping portion 231 is perpendicular to the supporting surface 241, and both the first partition wall 222 and the second partition wall 223 are, for example, perpendicular to the supporting surface 241. In this way, when the clamping member 23 is clamped and installed in the clamping groove 221, the clamping member 23 can be pressed in the vertical direction, which is convenient for installing the clamping member 23 on the clamping structure 22, and the installation efficiency is relatively high.

[0093] 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.

[0094] For example, the limiting portion 232 is provided with a first limiting surface 2324 for abutting against and limiting the end face 13 of the front panel 11 of the laminate 10, and the first limiting surface 2324 is set to be an arc-shaped surface. By making full use of the fact that the end face 13 of the front panel 11 is arc-shaped, when the first limiting surface 2324 is set to be an arc-shaped surface, the first limiting surface 2324 matches the shape of the end face 13 of the front panel 11, which can realize the pressing and fixing of the front panel 11 of the laminate 10, maximally guarantee the mechanical load of the component, and finally enable the photovoltaic frame 20 without an A surface to be used normally.

[0095] 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 requirements. 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 end face 13 of the front panel 11 by the clamping member 23.

[0096] In one embodiment, please refer to again Figures 3 to 6b, 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 facing 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) or the clamping portion 231, and the side of the first limiting surface 2324 facing away from the avoidance surface 2325 is connected to the first guide surface 2321. In this way, when the limit member 23 is installed on the snap-in structure 22 from top to bottom, the avoidance surface 2325 of the limit 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 limit member 23 can be smoothly installed on the snap-in structure 22. At the same time, the first limit 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.

[0097] 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.

[0098] Based on the above examples, please refer to Figure 3 and Figure 4 , 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 panel 12 is larger than the width dimension of the front panel 11, while the first limiting surface 2324 is pressed against the end surface 13 of the front panel 11, the bottom surface of the limiting portion 232 simultaneously presses the protruding portion 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 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.

[0099] Also, see Figure 6a For the laminate 10 whose width dimension of the back panel 12 is equal to the width dimension of the front panel 11, while the first limiting surface 2324 is pressed against the end surface 13 of the front panel 11, the bottom surface of the limiting portion 232 simultaneously presses the top surface of the first isolation wall 222, thereby improving the installation stability of the laminate 10 on the photovoltaic frame 20.

[0100] As some alternative solutions, please refer to Figure 6a and Figure 6b , and refer to Figure 8a and Figure 8b , 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. It 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 (that is, the first guiding surface 2321) includes but is not limited to 30° to 90°, and the specific setting can be flexibly adjusted according to actual requirements.

[0101] Exemplarily, the clamping structure 22 is used to abut against the end surface 13 of the back plate 12 of the laminate 10 and is in limit fit in the thickness direction of the laminate 10. In this way, under the condition that the clamping member 23 plays a limiting role on the front plate 11 of the laminate 10, the clamping structure 22 abuts against the end surface 13 of the back plate 12 of the laminate 10 and synchronously plays a limiting role on the end surface 13 of the back plate 12 of the laminate 10, and the installation stability of the laminate 10 on the photovoltaic frame 20 is enhanced, so that the laminate 10 can be stably installed on the photovoltaic frame 20.

[0102] 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 set as an arc surface. With such a setting, making full use of the arc characteristic of the end surface 13 of the back plate 12, when the second limiting surface 225 is set as an arc surface, the second limiting surface 225 matches the shape of the end surface 13 of the back plate 12, and the pressing and fixing of the back plate 12 of the laminate 10 can be realized, 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.

[0103] In addition, the second limiting surface 225 matches the shape of the end surface 13 of the back plate 12, which can not only improve the sealing performance and prevent the adhesive 251 from overflowing, but also, in the step of assembling the laminate 10 downward onto the photovoltaic frame 20, under the extrusion of the back plate 12 of the laminate 10 on the adhesive 251, the second limiting surface 225 can guide the adhesive 251 to wrap the end surface 13 of the back plate 12, which is beneficial to realizing the stable bonding and fixing of the laminate 10 on the photovoltaic frame 20.

[0104] Optionally, the arc angle of the second limiting surface 225 includes, but is not limited to, 30°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, 90°, 100°, 120°, 150°, 170°, 180°, 190°, or 200°, etc. Specifically, it can be flexibly adjusted and set according to actual needs. In this embodiment, the arc angle of the second limiting surface 225 is specifically, for example, 170° to 190°. 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 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.

[0105] Specifically, the second limiting surface 225 in this embodiment is formed on the side surface of the first partition wall 222 facing the back plate 12.

[0106] 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.

[0107] The structural form of the frame body 21 can be flexibly adjusted and designed according to actual needs, and will not be limited here. Exemplarily, 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.

[0108] Specifically, for example, the clamping structure 22 and the supporting portion 24 are connected to the outer surface of the first side wall 211.

[0109] 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 here. For example, the outer surface of the second side wall 212 can be flush with the surface of the second partition wall 223 facing away from the first partition wall 222, that is, as Figure 10 or Figure 11 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 partition wall 223 facing away from the first partition wall 222, that is, as Figure 12 shown.

[0110] Please refer to Figures 3 to 6a, 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 support surface 241, and the clamping member 23 and / or the clamping structure 22 are used to abut against the end face 13 of the laminate 10 and are in limit cooperation with the end face 13 in the thickness direction of the laminate 10.

[0111] For the above photovoltaic module, since it includes the above 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 here.

[0112] Among them, for the clamping member 23, specifically, the limiting portion 232 of the clamping member 23 is provided with a first limiting surface 2324 that abuts against and limits the end face 13 of the front panel 11. The first limiting surface 2324 matches the shape of the end face 13 of the front panel 11. In this way, the first limiting surface 2324 can fully abut against the end face 13 of the front panel 11, so as to effectively prevent the laminate 10 from disengaging upward, and make the laminate 10 stably installed on the photovoltaic frame 20.

[0113] Specifically, the end face 13 of the front panel 11 is arc-shaped, and the first limiting surface 2324 is correspondingly set as an arc surface. Of course, when the end face 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.

[0114] The clamping structure 22 is provided with a second limiting surface 225 that abuts against and limits the end face 13 of the back panel 12. The second limiting surface 225 matches the shape of the end face 13 of the back panel 12. In this way, the second limiting surface 225 can fully abut against the end face 13 of the back panel 12, so as to effectively prevent the laminate 10 from disengaging upward, and make the laminate 10 stably installed on the photovoltaic frame 20.

[0115] Specifically, the end face 13 of the back panel 12 is arc-shaped, and the second limiting surface 225 is correspondingly set as an arc surface. Of course, when the end face 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.

[0116] In one embodiment, 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 limits the limiting portion 232. In this way, the limiting portion 232 can not only abut against and limit the end face 13 of the front panel 11, but also abut against and limit the protruding portion 121 of the back panel 12, so as to make the laminate 10 firmly installed on the photovoltaic frame 20, effectively prevent the laminate 10 from disengaging upward, and enhance the reliability.

[0117] Please refer to Figures 13 to 15 , Figures 13 to 15 which respectively and sequentially show three different state diagrams during the assembly of the photovoltaic module according to the first embodiment of the present application. In one embodiment, another embodiment of the present application provides an assembly method for a photovoltaic module adopting any of the above embodiments. The assembly method includes the following steps:

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

[0119] Step S200: Snap and install the snap-in member 23 on the snap-in structure 22, so that the snap-in member 23 and / or the snap-in structure 22 abut against the end face 13 of the laminate 10 and are in limit fit 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 stationary state. While snapping and installing the snap-in member 23 on the snap-in structure 22 in the vertical direction, the snap-in member 23 and / or the snap-in structure 22 abut against the end face 13 of the laminate 10 and are in limit fit with the end face 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 defect of component explosion 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. It 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 the terms "first" and "second" appear, these terms are for descriptive purposes only 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 this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0124] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can 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 this application can be understood according to specific circumstances.

[0125] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be 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 "underneath" the second feature can 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 can also 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 so, the terms "vertical", "horizontal", "up", "down", "left", "right", and similar expressions used in this application are only for the purpose of illustration 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 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 merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
