Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic technology, and particularly relates to a photovoltaic module frame, a photovoltaic module combined frame, a photovoltaic module and a photovoltaic system. BACKGROUND

[0002] Figure 1 is a schematic diagram of a part of a photovoltaic module including a frame one in the prior art. Figure 1 As shown, the top surface 11 of the frame one 10 covers the edge of the front surface 21 of the laminated piece 20, and the two are bonded together by the sealing glue 30. In outdoor, the dust 12 distributed on the surface of the photovoltaic module cannot be completely removed by rainwater, and is deposited at the bottom of the photovoltaic module. Long-term accumulation, the dust 12 will block the battery piece in the laminated piece 20, generate hot spots, and affect the power generation and reliability of the photovoltaic module. At the same time, the acidic or alkaline substances in the dust 12 are easy to corrode the surface of the laminated piece 20, and reduce the light transmittance of the glass in the laminated piece 20. This phenomenon is particularly prominent in the power station installed at low angle, especially the roof distributed power station.

[0003] Figure 2 is a schematic diagram of a part of a photovoltaic module including a frame two in the prior art. Figure 2 The frame two 40 shown is a full-screen structure, in which, compared with the frame one 10 in Figure 1 , the part wrapping the edge of the laminated piece 20 and the part covering the edge of the front surface of the laminated piece 20 are removed, and the length of the long and short edges of the frame two 40 is consistent with the size of the laminated piece 20; therefore, the laminated piece 20 is only in contact and connected with the frame two 40 through the sealing glue 30. Figure 3 is a schematic diagram of a photovoltaic module including a frame two in the prior art, in which, after the laminated piece 20 is assembled with the frame two 40, from the front surface of the laminated piece 40, the frame two 40 is completely hidden under the laminated piece 20, and the edge of the front surface of the laminated piece 20 is not blocked at all, so that the sundries on the surface of the photovoltaic module can be removed from the edge of the laminated piece 20, avoiding the generation of hot spots, greatly reducing the cleaning cost of the photovoltaic module, and improving the power generation of the photovoltaic module. However, during the installation process, since the photovoltaic module does not have a glue overflow prevention structure, the sealing glue 30 will inevitably overflow outside the photovoltaic module, polluting the production line equipment and increasing the difficulty of cleaning. Moreover, the plane of the top of the sealing glue 30 and the frame two 40 directly pastes without a supporting part supporting the side surface of the laminated piece 20, and there is a problem that the bonding force is insufficient to fix the laminated piece 20.

[0062] The photovoltaic module frame in the embodiment of the application does not wrap the side edges and the front edge of the laminate, and full-screen design can be realized. This will be described in more detail below with reference to the drawings.

[0063] Figure 4 is a schematic view of the photovoltaic module frame in the first optional embodiment of the application. As shown in Figure 4 the photovoltaic module frame 50 in the embodiment of the application includes a frame body 52 and a support part 51 arranged above the frame body 52; the support part 51 includes an outer side edge baffle 511, an inner side edge baffle 512, one or more intermediate baffles 513 arranged between the outer side edge baffle 511 and the inner side edge baffle 512, and a glue storage groove 514 arranged between adjacent two baffles.

[0064] In the direction parallel to the front side or the back side of the laminate 20, the side of the photovoltaic module frame 50 far away from the laminate 20 is called the outer side, and the side opposite to the outer side is called the inner side; the support part 51 is arranged on the back side of the laminate 20, and in the direction perpendicular to the front side or the back side of the laminate 20, the end close to the laminate 20 is called the upper end of the support part 51, and the end far away from the laminate 20 is called the lower end of the support part 51. Figure 4 In the embodiment, the direction indicated by the positive direction of the X axis represents the inner side, and the direction indicated by the positive direction of the Y axis represents the upper end. In the embodiment of the application, the upper end of the intermediate baffle 513 extends to the inner side, and the lower end extends to the outer side.

[0065] In the embodiment of the application, the distance between the upper end of the baffle and the bottom of the frame body 52 is called the height of the upper end of the baffle, and the height of the upper end of each baffle decreases from the outside to the inside. Figure 4 In the embodiment shown in the first embodiment, the support part 51 has four baffles, which are the outer side edge baffle 511, the inner side edge baffle 512, and two intermediate baffles 513 arranged between the outer side edge baffle 511 and the inner side edge baffle 512. Figure 5 is a schematic view of the height of the upper end of the baffle in the first embodiment. Referring to Figure 5The distance H1 between the upper end of the outer edge baffle 511 and the bottom of the frame body 52 is the height of the upper end of the outer edge baffle 511, the distance H2 and H3 between the upper end of the two middle baffles 513 and the bottom of the frame body 52 is the height of the upper end of the two middle baffles 513, and the distance H4 between the upper end of the inner edge baffle 512 and the bottom of the frame body 52 is the height of the upper end of the inner edge baffle 512. In the direction from the outside to the inside (i.e. the direction indicated by the positive direction of the X-axis), the height H1 of the upper end of the outer edge baffle 511, the height H2 and H3 of the upper end of the two middle baffles 513, and the height H4 of the upper end of the inner edge baffle 512 decrease in turn. Figure 5

[0066] In the embodiment of the present application, the number of the middle baffles 513 included in the frame 50 of the photovoltaic module can be selectively set, and the number of the glue storage grooves 514 is determined according to the number of the middle baffles 513. For example:

[0067] In the embodiment shown in the figure, the support part 51 has three baffles, which are the outer edge baffle 511, the inner edge baffle 512, and the middle baffle 513 arranged between the outer edge baffle 511 and the inner edge baffle 512; correspondingly, the support part 51 has two glue storage grooves 514, which are respectively arranged between the outer edge baffle 511 and the middle baffle 513, and between the middle baffle 513 and the inner edge baffle 512. Figure 8

[0068] In the embodiment shown in the figure, the support part 51 has four baffles, which are the outer edge baffle 511, the inner edge baffle 512, and the two middle baffles 513 arranged between the outer edge baffle 511 and the inner edge baffle 512; correspondingly, the support part 51 has three glue storage grooves 514, which are respectively arranged between the outer edge baffle 511 and the outer middle baffle 513, between the two middle baffles 513, and between the inner middle baffle 513 and the inner edge baffle 512. Figure 4 Figure 13 Figure 14 Figure 15 Figure 19 In the embodiment shown in the figure, the support part 51 has four baffles, which are the outer edge baffle 511, the inner edge baffle 512, and the two middle baffles 513 arranged between the outer edge baffle 511 and the inner edge baffle 512; correspondingly, the support part 51 has three glue storage grooves 514, which are respectively arranged between the outer edge baffle 511 and the outer middle baffle 513, between the two middle baffles 513, and between the inner middle baffle 513 and the inner edge baffle 512.

[0069] In the embodiment shown in the figure, the support part 51 has four baffles, which are the outer edge baffle 511, the inner edge baffle 512, and the two middle baffles 513 arranged between the outer edge baffle 511 and the inner edge baffle 512; correspondingly, the support part 51 has three glue storage grooves 514, which are respectively arranged between the outer edge baffle 511 and the outer middle baffle 513, between the two middle baffles 513, and between the inner middle baffle 513 and the inner edge baffle 512. Figure 10 Figure 12 ​​​​​​​In the shown optional embodiment, the support part 51 has five baffles, namely, an outer edge baffle 511, an inner edge baffle 512, and three intermediate baffles 513 arranged between the outer edge baffle 511 and the inner edge baffle 512; correspondingly, the support part 51 has four glue storage grooves 514, which are respectively located between the outer edge baffle 511 and the outer intermediate baffle 513, between the outer intermediate baffle 513 and the middle intermediate baffle 513, between the middle intermediate baffle 513 and the inner intermediate baffle 513, and between the inner intermediate baffle 513 and the inner edge baffle 512.

[0070] The number of the baffles and the glue storage grooves 514 in the foregoing optional embodiments is only an example, and other numbers of the baffles and the glue storage grooves 514 can also be arranged according to actual conditions, which is not specifically limited in the present application.

[0071] The photovoltaic module frame 50 and the laminate 20 are bonded together by the sealant 30. Figure 7 Figure 4 A schematic diagram of the installation process of the photovoltaic module frame is shown in FIG. 4. Figure 7 As shown in FIG. 4, during the installation process of the photovoltaic module frame 50, the distance between the photovoltaic module frame 50 and the laminate 20 gradually decreases, and thus the sealant 30 arranged between the photovoltaic module frame 50 and the laminate 20 is gradually extruded. In the embodiment of the present application, the height of the upper end of the outer edge baffle 511 is greater than the height of the upper end of the intermediate baffle 513 and the height of the upper end of the inner edge baffle 512, and thus, as the distance between the photovoltaic module frame and the laminate 20 decreases, the upper end of the outer edge baffle 511 first contacts the back surface of the laminate 20, some of the sealant 30 can flow into the corresponding glue storage groove 514, and most of the sealant 30 can move toward the intermediate baffle 513 and the inner edge baffle 512 during the extrusion process, i.e., move toward Figure 6 the direction indicated by the positive direction of the X-axis. Since the height of the upper end of the intermediate baffle 513 is greater than the height of the upper end of the inner edge baffle 512, the sealant 30 will continue to flow toward the inner edge baffle 512, and when the amount of the sealant 30 is relatively large, the sealant 30 can further overflow to the inner side of the photovoltaic module frame 50.

[0072] Figure 8 A schematic diagram of the photovoltaic module frame in the second optional embodiment of the present application is shown in FIG. 5, Figure 9 Figure 8 A schematic diagram of the installation process of the photovoltaic module frame is shown in FIG. 6. Figure 9 ​​As shown, during the installation process of the photovoltaic module frame 50, the distance between the photovoltaic module frame and the laminate 20 gradually decreases, and then the sealant 30 arranged between the photovoltaic module frame 50 and the laminate 20 is gradually extruded. Since the height of the upper end of the outer edge baffle 511 is greater than the height of the upper end of the middle baffle 513 and the height of the upper end of the inner edge baffle 512, as the distance between the photovoltaic module frame and the laminate 20 decreases, the upper end of the outer edge baffle 511 first contacts the back of the laminate 20, some of the sealant 30 can flow into the corresponding glue storage groove 514, and most of the sealant 30 can move towards the middle baffle 513 and the inner edge baffle 512 during the extrusion process, that is, towards the direction indicated by the positive direction of the X-axis. Figure 9 Since the height of the upper end of the middle baffle 513 is greater than the height of the upper end of the inner edge baffle 512, the sealant 30 will continue to flow to the inner edge baffle 512, and when the amount of sealant 30 is relatively large, the sealant 30 can further overflow to the inner side of the photovoltaic module frame 50.

[0073] In the embodiment of the present application, the curved structure of the glue storage groove 514 is similar to a "claw", which increases the bonding area between the sealant 30 and the photovoltaic module frame 50, increases the friction, and can effectively slow down or avoid the peeling of the photovoltaic module frame 50 and the sealant 30. The extension direction of the upper end of the middle baffle 513 is towards the inner side of the photovoltaic module frame 50, which cooperates with the direction of the opening of the glue storage groove 514 to guide the overflow of the sealant 30 to the inner side of the photovoltaic module frame 50. That is, the glue storage groove 514 in the embodiment of the present application not only has the function of storing glue, but also has the function of guiding the directional flow of the sealant 30.

[0074] In the embodiment of the present application, the support part 51 containing the glue storage groove 514 is arranged above the frame body 52, so that the storage amount of the sealant 30 between the photovoltaic module frame 50 and the laminated piece 20 is increased, the bonding effect between the photovoltaic module frame 50 and the laminated piece 20 is improved, and the reliability of the photovoltaic module is improved. The upper end of the intermediate baffle 513 extends inward, and the lower end extends outward, so that the sealant 30 is guided to move inward of the photovoltaic module frame 50, and the overflow of the sealant 30 to the outside of the photovoltaic module frame 50 is slowed down or avoided. The height of the upper end of each baffle decreases from outside to inside, so that the overflow to the outside of the photovoltaic module frame 50 is further slowed down or avoided. In addition, the photovoltaic module frame 50 in the embodiment of the present application can guide the sealant to the inside of the frame body 52, form a glue line on the back of the laminated piece 20, facilitate observation of the overflow effect during installation, and has simple structure, low material consumption, low cost and light weight. In addition, the photovoltaic module frame 50 in the embodiment of the present application does not wrap the side edges and the front edges of the laminated piece 20, can realize full-screen design, facilitate dust discharge, slow down or avoid the generation of hot spots due to dust accumulation, reduce the light transmittance of the glass in the laminated piece 20, and improve the power generation efficiency and service life of the photovoltaic module.

[0075] In the embodiment of the present application, the distance between the lower end of the baffle and the bottom of the frame body 52 is referred to as the height of the lower end of the baffle. Figure 6 is a schematic diagram of the height of the lower end of the baffle in the first embodiment. As shown in Figure 6 , the distance H5 between the lower end of the outer edge baffle 511 and the bottom of the frame body 52 is the height of the lower end of the outer edge baffle 511, the distances H6 and H7 between the lower ends of the two intermediate baffles 513 and the bottom of the frame body 52 are the heights of the lower ends of the two intermediate baffles 513, and the distance H8 between the lower end of the inner edge baffle 512 and the bottom of the frame body 52 is the height of the lower end of the inner edge baffle 512.

[0076] In Figure 4 , Figure 10 , Figure 12 and Figure 17 the optional embodiment, the height of the lower end of each baffle decreases from outside to inside; in Figure 8 , Figure 13 , Figure 15 , Figure 19 the optional embodiment, the height of the lower end of each baffle is the same. In the embodiment of the present application, the height of the upper end of each baffle decreases from outside to inside, and if the height of the lower end of each baffle is the same, the capacity of each glue storage groove decreases from outside to inside, so that the use amount of the sealant 30 is reduced. Figure 9 , Figure 14 and Figure 16As shown, the weight and cost of the photovoltaic module are reduced. Compared with the embodiment in which the heights of the lower ends of the respective baffles are the same, by sequentially reducing the heights of the lower ends of the respective baffles from the outside to the inside, the capacity of the respective glue storage grooves on the inner side can be increased, and thus the storage amount of the sealant 30 between the photovoltaic module frame 50 and the laminated piece 20 is increased, the adhesion effect between the photovoltaic module frame 50 and the laminated piece 20 is improved, and the reliability of the photovoltaic module is improved, as shown in Figure 7 、 Figure 11 and Figure 17 .

[0077] In the embodiment of the present application, the upper end of the inner side edge baffle 512 can be aligned with the frame body, i.e., the upper end of the inner side edge baffle 512 and the inner side surface of the frame body 52 are in the same vertical plane, as shown in Figure 4 、 Figure 8 and Figure 17 . The vertical plane mentioned here refers to a plane perpendicular to the front or back surface of the laminated piece 20, i.e., a plane parallel to the Y axis. In alternative embodiments of the present application, the upper end of the inner side edge baffle 512 extends inwardly to the inner side of the inner side surface of the frame body 52 to form an overhanging portion 5121, i.e., the upper end of the inner side edge baffle 512 and the inner side surface of the frame body 52 are not in the same vertical plane, and the upper end of the inner side edge baffle 512 extends to the inner side of the inner side surface of the frame body 52, as shown in Figure 10 、 Figure 12 、 Figure 13 、 Figure 15 and Figure 19 . By extending the upper end of the inner side edge baffle 512 beyond the frame body 52, the innermost glue storage groove 514 has a V-shaped structure, the upper end of the inner side edge baffle 512 can guide the sealant 30 to the inner side of the frame body 52, and form a glue line on the back surface of the laminated piece 20, which facilitates observation of the overflow effect during installation, and the structure is simple, the amount of material used is small, and thus the cost and weight are low.

[0078] The overhanging portion 5121 can be a planar structure or a non-planar structure. In some alternative embodiments of the present application, as shown in Figure 10 、 Figure 13 、 Figure 15 and Figure 19 , the overhanging portion 5121 is a convex structure that protrudes upward. By making the overhanging portion 5121 a convex structure that protrudes upward, the sealant 30 can be better guided to the inner side of the frame body 52, and the use amount of the sealant 30 can be reduced under the condition of increasing the contact area between the sealant 30 and the laminated piece 20, thereby reducing the weight and cost of the photovoltaic module on the basis of ensuring the adhesion reliability between the photovoltaic module frame 50 and the laminated piece 20. In other alternative embodiments of the present application, as shown in Figure 12As shown, the protruding portion 5121 is a downwardly recessed groove structure. By making the protruding portion 5121 a downwardly recessed groove structure, the amount of sealant 30 in the sealant storage groove 514 can be increased, and the adhesion effect between the sealant 30 in the sealant storage groove 514 and the laminated piece 20 can be improved.

[0079] The intermediate baffle 513 in the embodiments of the present application has a plate structure, and a person skilled in the art can set the specific structure form of the plate structure according to actual conditions. For example, in the optional embodiment shown in Figure 4 、 Figure 10 、 Figure 12 and Figure 17 , the intermediate baffle 513 is a planar baffle. By making the intermediate baffle 513 a planar baffle, the amount of sealant 30 in the sealant storage groove 514 can be increased as much as possible, the adhesion effect can be improved, and processing and manufacturing are facilitated. For another example, in the optional embodiment shown in Figure 8 、 Figure 10 、 Figure 13 、 Figure 15 and Figure 19 , the inner side edge baffle 512 is an upwardly protruding convex baffle. By making the inner side edge baffle 512 an upwardly protruding convex baffle, the sealant 30 can be better guided to move to the inner side of the photovoltaic module frame 50. In addition to making the whole of the inner side edge baffle 512 a planar baffle or an upwardly protruding convex baffle, the inner side edge baffle 512 in the embodiments of the present application can also be set to have different structures in the upper end region and the lower end region, for example, only the upper end region is a planar baffle or an upwardly protruding convex baffle.

[0080] The inner side edge baffle 512 in the embodiments of the present application has a plate structure, and a person skilled in the art can set the specific structure form of the plate structure according to actual conditions. For example, in the optional embodiment shown in Figure 4 and Figure 17 , the inner side edge baffle 512 is a planar baffle. By making the inner side edge baffle 512 a planar baffle, the amount of sealant 30 in the sealant storage groove 514 can be increased as much as possible, the adhesion effect can be improved, and processing and manufacturing are facilitated. For another example, in the optional embodiment shown in Figure 8 、 Figure 13 、 Figure 15 and Figure 19 , the intermediate baffle 513 is an upwardly protruding convex baffle. By making the intermediate baffle 513 an upwardly protruding convex baffle, the sealant 30 can be better guided to move to the inner side of the photovoltaic module frame 50. In addition to making the whole of the intermediate baffle 513 a planar baffle or an upwardly protruding convex baffle, the intermediate baffle 513 in the embodiments of the present application can also be set to have different structures in the upper end region and the lower end region, for example, only the upper end region is a planar baffle or an upwardly protruding convex baffle. In addition, as Figure 12As shown, the inner side edge baffle 512 can also be a downwardly recessed concave baffle. By making the inner side edge baffle 512 a downwardly recessed concave baffle, the amount of sealant 30 in the sealant storage groove 514 can be increased, and the adhesion effect between the sealant 30 in the sealant storage groove 514 and the laminated piece 20 can be improved.

[0081] The outer side edge baffle 511 in the embodiment of the present application has a plate structure, and a person skilled in the art can set the specific structure form of the plate structure according to actual conditions. In some optional embodiments of the present application, the outer side edge baffle 511 is a vertical baffle, which can be a planar baffle or a non-planar baffle. For example, in Figure 4 、 Figure 8 、 Figure 10 、 Figure 12 and Figure 13 the optional embodiment shown, the outer side edge baffle 511 is a vertical baffle, and the inner side upper end of the outer side edge baffle 511 is inwardly protruded, so that the inwardly protruded part of the inner side upper end of the outer side edge baffle 511 can play a guiding role to guide the sealant 30 to move to the inner side of the photovoltaic module frame 50. For another example, in Figure 15 the optional embodiment shown, the upper end of the outer side edge baffle 511 extends to the inner side, and the lower end extends to the outer side. In this way, the outer side edge baffle 511 is arranged, which can guide the sealant 30 to move to the inner side of the photovoltaic module frame, and can form an additional sealant storage groove 515 on the outer side of the outer side edge baffle 511. During the process of assembling the photovoltaic module frame and the laminated piece 20, if the sealant 30 overflows outwardly from between the photovoltaic module frame 50 and the laminated piece 20, the additional sealant storage groove 515 can accommodate the overflowing sealant 30, as Figure 16 shown, to avoid the sealant 30 directly overflowing from the outer side edge of the photovoltaic module frame 50, and to reduce the cleaning process. In addition, if the amount of sealant 30 fluctuates during the sealing process, and the amount of extruded glue is uneven, the excess sealant 30 can flow into the additional sealant storage groove 515, to slow down or avoid the sealant 30 directly overflowing to the outer side from the photovoltaic module edge, and to reduce the cleaning process.

In the embodiment of the present application, the support part 51 can be regarded as a new A surface (so-called "new", which means different from the A surface in the prior art) of the photovoltaic module frame, the first outer side vertical plate 521a can be regarded as a B surface of the photovoltaic module frame 50, the first bottom plate 522a can be regarded as a C surface of the photovoltaic module frame 50, and the first inner side vertical plate 523a can be regarded as a D surface (i.e. the inner side surface of the photovoltaic module frame 50) of the photovoltaic module frame 50. The first outer side vertical plate 521a, the first bottom plate 522a, the first inner side vertical plate 523a and the support part 51 can be connected in a detachable manner, or can be integrally formed. Figure 4 In the optional embodiment shown, the cavity structure is a rectangular structure, and in actual application, it can also be designed into other structures according to actual needs, for example, a trapezoidal structure, a regular polygon structure, or a polygonal structure with a curved surface in part of the bottom plate. By making the support part 51 participate in the enclosure to form the cavity structure, the structure of the photovoltaic module frame 50 can be simplified, the material consumption of the photovoltaic module frame can be reduced, and thus the weight and cost of the photovoltaic module frame can be reduced.

The top plate 524, the second outer side vertical plate 521b, the second bottom plate 522b and the second inner side vertical plate 523b can be connected in a detachable manner, or can be integrally formed. Figure 17In the shown optional embodiment, the cavity structure is a rectangular structure, and in actual application, other structures can also be designed according to actual needs, such as trapezoidal structure, regular polygon structure, or multi-edge structure with part of the top plate and bottom plate being curved surface. By making the top plate 524, the second outer side vertical plate 521b, the second bottom plate 522b, and the second inner side vertical plate 523b into a cavity structure with hollow interior, and by making the support part 51 not participate in the formation of the cavity structure but be arranged above the cavity structure, the photovoltaic module frame 50 can be fixed by the pressing block 60. In order to improve the stability between the support part 51 and the frame main body 52, one or more connecting parts 525 can be arranged, such as shown in Figure 17 The upper end of the connecting part 525 is connected with the support part 51, and the lower end is connected with the cavity structure.

By cooperating the mounting groove 526 with the pressing block 60, the pressing block 60 can be prevented from directly contacting the glass surface of the laminated piece 20, the glass of the laminated piece 20 can be prevented from being crushed, and the laminated piece 20 can be prevented from being blocked by the pressing block 60. In addition, by adopting this design, the height of the pressing block 60 can be further reduced, and the material of the pressing block 60 can be saved.

For example, the anti-skid structure 527 can be knurling structure, array of protrusions, array of grooves, frosted surface, or the like arranged on the upper surface and / or lower surface inside the mounting groove 526. For another example, the anti-skid structure 527 includes grooves arranged on the upper surface and / or lower surface inside the mounting groove 526 and adhesive tape cooperated with the grooves.

The upper end of the intermediate baffle extends inward, and the lower end extends outward, so that the sealant can be guided to move to the inner side of the frame of the photovoltaic module, and the overflow of the sealant to the outer side of the frame of the photovoltaic module can be slowed down or avoided. The height of the upper end of each baffle decreases from the outside to the inside, so that the overflow to the outer side of the frame of the photovoltaic module can be further slowed down or avoided. In addition, in the case that the amount of sealant is sufficient, the frame of the photovoltaic module in the embodiment of the present application can guide the sealant to the inner side of the frame body, form a glue line on the back of the laminated piece, facilitate observation of the overflow effect during installation, and has the advantages of simple structure, less material consumption, low cost and light weight.
