Its function is to encapsulate the battery cells, glass, backplane and other materials, enhance the strength of the module, and facilitate the transportation, installation and protection of the photovoltaic module.

[0003] The traditional four-sided frame structure of photovoltaic modules mainly includes A-side body, B-side body, C-side body, cavity, laminated component tank body and other parts. The corners are connected in the cavity at both ends of the long and short frames to form the connection between the long and short sides. The laminated component power generation unit is installed in the laminated component tank body. The A-side body is against the top surface of the laminated component tank body, the B-side body is the side of the frame, and the C-side body is opposite to the A-side body and is generally located on the back of the photovoltaic module.

[0004] Among them, the A-surface body in the frame of the photovoltaic module forms the top of the frame, and the A-surface body of the frame is generally higher than the laminate to form a laminate groove for installing the laminate. Since the A-surface body of the frame is higher than the laminate, after the photovoltaic module is installed outdoors, although it is washed by rain, dust and the like will still accumulate on the inner side of the A-surface body of the bottom frame, blocking the surface of the lower part of the photovoltaic module, thereby affecting the power generation effect of the photovoltaic module.

[0010] According to a photovoltaic module frame provided by the present invention, both end portions of the first frame are cut to form inclined surfaces, and both end portions of the second frame except for the second A-surface body are also cut to form inclined surfaces that fit with the ends of the first frame; the first cavity end and the second cavity end are connected by an angle code, so that the first frame and the second frame ends are fit and connected, and the second A-surface body covers the first frame.

[0011] According to a photovoltaic module frame provided by the present invention, the top of the first B surface body is not higher than the upper surface of the laminate, and the height difference D between the top of the first B surface body and the upper surface of the laminate satisfies: 0.2mm≤D≤1.5mm.

[0012] According to a photovoltaic module frame provided by the present invention, the laminate is bonded to the bottom mounting groove of the laminate and the side mounting groove of the laminate by sealing silicone, and overflow grooves are provided in the bottom mounting groove of the laminate and the side mounting groove of the laminate.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0030] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean 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", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0031] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0032] Combine the following Figures 1 to 8 The specific structure of the photovoltaic module frame and the photovoltaic module of the present invention is described.

[0033] An embodiment of the present invention provides a photovoltaic module frame, combined with Figure 1 and Figure 3 As shown, a laminate 1 is installed, including a first frame 2, the first frame 2 is used as the bottom frame of the photovoltaic module frame, and a laminate bottom mounting groove 21 is constructed on the first frame 2. The laminate bottom mounting groove 21 is a right-angle bracket structure. The bottom end of the laminate 1 is installed in the laminate bottom mounting groove 21, and the upper surface of the laminate 1 is higher than the laminate bottom mounting groove 21.

[0034] It can be understood that the photovoltaic module frame of this embodiment uses the first frame 2 as the bottom frame of the photovoltaic module frame, and supports the bottom end of the laminate 1 through the bottom mounting groove 21 of the laminate on the upper part of the first frame 2. Since the upper surface of the laminate 1 is higher than the bottom mounting groove 21 of the laminate, there is no A-surface obstruction at the bottom of the laminate. After the photovoltaic module is installed outdoors, dust, leaves and other debris falling on the upper surface of the laminate 1 will fall from the bottom of the laminate 1 under the action of its own weight or the action of rain, and will not cause dust deposition. The photovoltaic module frame of this embodiment can improve the anti-dust accumulation performance of the photovoltaic module by using the first frame 2 without the A surface as the bottom frame. The surface of the photovoltaic module is less likely to accumulate dust, leaves and other debris, thereby ensuring the power generation performance of the photovoltaic module when it is running outdoors.

[0035] In some specific examples of the photovoltaic module frame of the present invention, the photovoltaic module frame also includes a pair of second frames 3 used as two side frames of the photovoltaic module frame and a third frame 4 used as the top frame of the photovoltaic module frame, and the second frame 3 is constructed with a laminate side end mounting groove 31 for mounting the side end of the laminate 1, and the laminate side end mounting groove 31 is a rectangular groove structure with one side open, and the laminate side end mounting grooves 31 of the pair of second frames 3 are arranged opposite to each other; the third frame 4 is the same as the second frame 3 or the same as the first frame 2.

[0036] Combination Figure 1 , Figure 3 and Figure 5 As shown, a first frame 2, a pair of second frames 3 and a third frame 4 are connected to form a rectangular photovoltaic module frame, the two side ends of the laminate 1 are respectively installed in the laminate side end mounting grooves 31 of the second frame 3, the bottom end of the laminate 1 is installed in the laminate bottom end mounting groove 21 of the first frame 2, and the top end of the laminate 1 is installed in the third frame 4. Among them, the laminate side end mounting grooves 31 on the second frames 3 on both sides are rectangular groove structures with one side open, which can limit the laminate 1 laterally and in the direction perpendicular to the laminate 1 to ensure the installation reliability of the photovoltaic module frame; the first frame 2 at the bottom end is a right-angle bracket structure, which can limit the bottom end of the laminate 1 without causing dust deposition; the third frame 4 at the top end can be the structure of the first frame 2 or the structure of the second frame 3, and is mainly used to limit the top end of the laminate 1. In summary, the first frame 2, the second frame 3 and the third frame 4 form limits on the four sides of the laminate 1, and the second frame 3 forms a limit on the vertical direction of the laminate 1, which together ensure the installation reliability of the photovoltaic module without causing dust accumulation at the bottom.

[0037] In some specific embodiments of the photovoltaic module frame of the present invention, see Figure 2As shown, the first frame 2 includes a first B-surface body 22, a first C-surface body 23, a first transverse support body 24 and a first vertical support body 25. The first transverse support body 24 is connected to the middle part of the first B-surface body 22 to form a laminate bottom mounting groove 21 with the upper part of the first B-surface body 22; the first B-surface body 22, the first C-surface body 23, the first transverse support body 24 and the first vertical support body 25 together form a first cavity 26.

[0038] See also Figure 3 As shown, it can be understood that the bottom end surface of the laminate 1 is installed in the bottom end mounting groove 21 of the laminate composed of the first transverse support body 24 and the first B surface body 22. The bottom end mounting groove 21 of the laminate is a right-angle bracket. The first transverse support body 24 supports the laminate 1, and the first B surface body 22 limits the end surface of the laminate 1. The top of the first B surface body 22 is not higher than the upper surface of the laminate 1, and the height difference D between the top of the first B surface body 22 and the upper surface of the laminate 1 satisfies: 0.2mm≤D≤1.5mm, so that the upper surface of the bottom end of the laminate 1 is unobstructed and does not cause dust deposition. It should be understood that D satisfies 0mm≤D≤2mm to achieve unobstructed upper surface of the bottom end of the laminate 1, but considering the situation that the top of the first B surface body 22 is flush with the upper surface of the laminate 1, dust will still accumulate in the gap. Therefore, in this embodiment, the top of the first B surface body 22 is selected to be lower than the upper surface of the laminate 1, that is, D≥0.2mm. The first cavity 26 formed by the first B-surface body 22, the first C-surface body 23, the first transverse support body 24 and the first vertical support body 25 reduces the material usage of the first frame 2, making the frame lighter. At the same time, the corner code is inserted into the end of the first cavity 26 to achieve connection with other frames.

[0039] In other specific embodiments of the photovoltaic module frame of the present invention, see Figure 4 As shown, the second frame 3 includes a second A surface body 32, a second B surface body 33, a second C surface body 34, a second lateral support body 35 and a second vertical support body 36. The second A surface body 32 and the second lateral support body 35 are connected to the second B surface body 33 to form a laminate side end mounting groove 31; the second B surface body 33, the second C surface body 34, the second lateral support body 35 and the second vertical support body 36 together enclose a second cavity 37.

[0040] See also Figure 5As shown, it can be understood that the side end face of the laminate 1 is installed in the laminate side end installation groove 31 composed of the second A surface body 32, the second transverse support body 35 and the second B surface body 33. The laminate side end installation groove 31 is a rectangular groove structure with one side open. The second transverse support body 35 supports the laminate 1, the second B surface body 33 limits the side end face of the laminate 1, and the second A surface body 32 limits the upper surface of the laminate 1, thereby ensuring the installation reliability of the laminate 1. The second cavity 37 formed by the second B surface body 33, the second C surface body 34, the second transverse support body 35 and the second vertical support body 36 reduces the material usage of the second frame 3, making the frame lighter. At the same time, the corner code is inserted into the end of the second cavity 37 to achieve connection with the first cavity 26 of the first frame 2 in the above embodiment.

[0041] In some embodiments of the photovoltaic module frame of the present invention, the end portions of the first frame 2 are cut to form inclined surfaces, and the end portions of the second frame 3 except the second A-surface body 32 are also cut to form inclined surfaces that fit with the ends of the first frame 2; the end portion of the first cavity 26 is connected to the end portion of the second cavity 37 by an angle code, so that the ends of the first frame 2 and the second frame 3 are fitly connected, and the second A-surface body 32 covers the first frame 2.

[0042] It is understandable that in this embodiment, there is no A surface in the structure of the first frame 2. Figure 6 As shown, the structure of the second frame 3 includes an A surface (a second A surface body 32), and the end of the first cavity 26 of the first frame 2 and the end of the second cavity 37 of the second frame 3 are connected by threading the corner code to realize the connection between the first frame 2 and the second frame 3. In order to ensure the connection reliability of the first frame 2 and the second frame 3, the ends of the first frame 2 and the second frame 3 are adapted to be cut at 45 degrees or other angles, wherein the second A surface body 32 of the second frame 3 is not cut. After the ends of the first frame 2 and the second frame 3 are fitted and connected, the first frame 2 and the second frame 3 are combined. Figure 7 and Figure 8 As shown, the second A-surface 32 of the second frame 3 covers the end of the first frame 2 , thereby effectively protecting the glass at the four corners of the laminate 1 .

[0043] In some embodiments of the photovoltaic module frame of the present invention, the laminate 1 is bonded to the laminate bottom mounting groove 21 and the laminate side mounting groove 31 by sealing silicone, and the laminate bottom mounting groove 21 and the laminate side mounting groove 31 are both provided with overflowing glue grooves. It can be understood that since the laminate bottom mounting groove 21 of the first frame 2 has no A surface, the amount of sealing silicone used can be reduced compared to the traditional frame. The overflowing glue grooves are both provided in the laminate bottom mounting groove 21 and the laminate side mounting groove 31, which can reduce the overflowing glue after the laminate 1 is glued to the photovoltaic module frame, and the excess sealing silicone will remain in the overflowing glue groove. Based on the fluidity of the colloid, the sealing silicone in the overflowing glue groove can also be used to fill the glue when the subsequent bonding part lacks glue. Based on the overflowing glue groove of this embodiment, the amount of glue required for the frame bonding can be reduced, and the overflowing glue on the back of the photovoltaic module can also be reduced.

[0044] In particular, in some specific examples, see again Figure 3 As shown, the first transverse support body 24 forms a first recessed portion 51 near the first B-surface body 22, the first transverse support body 24 forms a second recessed portion 52 away from the first B-surface body 22, and the end of the first transverse support body 24 away from the first B-surface body 22 forms a hook-shaped portion 53. The first recessed portion 51, the second recessed portion 52 and the hook-shaped portion 53 are constructed on the first transverse support body 24 to form the first glue overflow groove 5 of the bottom end mounting groove 21 of the laminate.

[0045] It can be understood that in this example, the first recessed portion 51 and the second recessed portion 52 can both form glue storage areas. When using sealing silicone to bond the laminate 1 and the mounting groove 21 at the bottom end of the laminate, excess sealing silicone flows in the first glue overflow groove 5 to the first recessed portion 51 and the second recessed portion 52 for storage. At the same time, a hook-shaped portion 53 is provided at the end of the first glue overflow groove 5. The hook-shaped portion 53 can increase the difficulty of the sealing silicone overflowing from the seal. The excess sealing silicone will remain in the second recessed portion 52 under the action of the hook-shaped portion 53, thereby effectively preventing the sealing silicone from overflowing from the seal to the back of the photovoltaic module.

[0046] For other specific examples, see Figure 5 As shown, a third recessed portion 61 is formed at a portion of the second A surface body 32 close to the second B surface body 33, a hook-shaped groove 62 is formed at a portion of the second A surface body 32 away from the second B surface body 33, and a fourth recessed portion 63 is formed at a portion of the second lateral support body 35 close to the second B surface body 33. The third recessed portion 61, the hook-shaped groove 62 and the fourth recessed portion 63 constitute a second glue overflow groove 6 of the side end mounting groove 31 of the laminate.

[0047] It can be understood that, in this example, the third recessed portion 61 and the fourth recessed portion 63 form a glue storage portion. When the sealing silicone is used to bond the laminate 1 and the side end mounting groove 31 of the laminate, the excess sealing silicone flows in the second glue overflow groove 6 to the third recessed portion 61 and the fourth recessed portion 63 for storage. At the same time, a hook-shaped groove 62 is provided at the end of the second glue overflow groove 6. The hook-shaped groove 62 can increase the difficulty of the sealing silicone overflowing from the sealing portion. The excess sealing silicone will remain in the hook-shaped groove 62 and will not easily overflow.

[0048] It should be understood that in the above examples, whether it is the structural design of the first overflow glue groove 5 or the structural design of the second overflow glue groove 6, they are all some specific embodiments provided by the present invention. Other similar slots with anti-overflow glue function can also be applied in the present invention. The overflow glue groove structure is not particularly limited here. All similar slots with anti-overflow glue function can be used in the structure of the present invention to reduce the amount of back glue overflow after the laminate 1 is assembled with the frame. Moreover, in the above examples, the overflow glue groove is set on the horizontal support body. The number of overflow glue grooves can be multiple, which is set according to actual needs. Multiple overflow glue grooves work together to reduce the back glue overflow after the laminate 1 is assembled with the frame, thereby improving the appearance of the component.

[0049] On the other hand, the present invention also provides a photovoltaic module. Specifically, in some embodiments, the photovoltaic module includes the photovoltaic module frame in any one of the above embodiments or examples. It can be understood that the types of photovoltaic modules in this embodiment include but are not limited to crystalline silicon photovoltaic modules, amorphous silicon photovoltaic modules, thin-film photovoltaic modules, perovskite photovoltaic modules, organic photovoltaic modules, etc. Since the photovoltaic module in this embodiment includes the photovoltaic module frame of the present invention, the photovoltaic module of this embodiment must have the advantages in the above photovoltaic module frame embodiment, so that the anti-dust performance of the photovoltaic module of this embodiment is greatly improved, and the surface of the module is less likely to accumulate dust, leaves and other debris, ensuring the power generation performance of the module when it is running outdoors; the glass at the four corners of the photovoltaic module can be effectively protected; through the design of the overflow glue groove, the overflow glue on the back of the photovoltaic module during and after installation can be reduced.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
