However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0040] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

The "numerical value" in the numerical interval can be any quantitative value, such as a number, percentage, ratio, etc. The term "numerical interval" can be broadly included to include percentage intervals, ratio intervals, proportion intervals, etc.

[0046] This application provides an encapsulation frame to solve the problem that traditional photovoltaic module encapsulation requires corner brackets and corresponding long and short frame frames with cavities, resulting in high material costs and hindering cost reduction and efficiency improvement. The encapsulation frame will be described below with reference to the accompanying drawings.

[0047] The encapsulation border provided in this application embodiment is exemplary; please refer to [link / reference]. Figure 1 As shown Figure 1 This is a schematic diagram of a corner code structure according to an embodiment of the present invention. The encapsulation frame of this application can be used for laminate encapsulation to form a photovoltaic module.

[0048] To more clearly illustrate the structure of the package frame, the following description of the package frame will be provided in conjunction with the accompanying drawings.

[0049] For example, please refer to Figure 1As shown, a corner code structure 300 includes a first corner code component 310 and a second corner code component 320. The first corner code component 310 extends along a first plane, and the second corner code component 320 extends along a second plane. One side of the first corner code component 310 is connected to one side of the second corner code component 320, so that the corner code structure 300 is bent. The first corner code component 310 and the second corner code component 320 are respectively used to be embedded in the slots 160 on the outer sidewalls of adjacent packaging frames 100 to achieve the connection of adjacent packaging frames 100. The first plane and the second plane are two different planes, and the extension directions of the first plane and the second plane are shown in [reference needed]. Figure 1 The direction is indicated by the straight arrow in the middle. It should be noted that in this application, after the encapsulation frame 100 is encapsulated with the laminate 200, the mounting groove 140 on the encapsulation frame 100 faces the laminate 200. Therefore, in the vertical direction, the side of the encapsulation frame 100 facing the laminate 200 is defined as the inner side, and the side away from the laminate 200 is defined as the outer side.

[0050] The corner code structure 300 in this application connects adjacent packaging frames 100 by providing a first corner code component 310 extending along a first plane and a second corner code component 320 extending along a second plane, which are respectively embedded in slots 160 on the outer sidewalls of adjacent packaging frames 100. The corner code structure 300 of this application can be adapted to cavity-less packaging frames 100 to connect adjacent packaging frames 100. Compared with conventional technologies, the use of the corner code structure 300 in this application can reduce at least one sidewall of the packaging frame 100 and reduce the material required for its fabrication. Furthermore, the corner code structure 300 of this application only requires the first corner code component 310 extending along the first plane and the second corner code component 320 extending along the second plane. Compared with corner codes of conventional technologies, it has a simpler structure, simpler processing, and requires less material, thus achieving cost reduction and efficiency improvement.

[0051] In some embodiments, the first plane is perpendicular to the second plane. In this application, when the first plane and the second plane are perpendicularly arranged, the first corner code component 310 and the second corner code component 320 are generally in a vertical state. At this time, the corner code structure 300 can be adapted to the packaging frame 100 that is spliced ​​perpendicularly to each other. The corner code structure 300 described above can be applied to the conventionally shaped laminate 200, that is, the rectangular laminate 200.

[0052] In some embodiments, the first corner code component 310 and the second corner code component 320 are connected as a single unit. The first corner code component 310 and the second corner code component 320 can be integrally formed during processing. The processing methods for the first corner code component 310 and the second corner code component 320 can be one or more of the following: 3D printing, injection molding, laser cutting, etc.

[0053] In some embodiments, the materials used to manufacture the first corner code component 310 and the second corner code component 320 can be metals, alloys, and composite materials. For example, the materials used to manufacture the first corner code component 310 and the second corner code component 320 can include aluminum, aluminum alloys, polyurethane, glass fiber, etc., as long as the corner code structure 300 can have a certain structural strength.

[0054] In some embodiments, the first corner code component 310 and the second corner code component 320 are rectangular in shape. It is easy to understand that in other examples, the first corner code component 310 and the second corner code component 320 can also be other shapes, as long as they can fit into the slot 160.

[0055] In some embodiments, the first corner code component 310 includes a first top edge 311, a first bottom edge 312, and a set of opposing first side edges 313 located between the first top edge 311 and the first bottom edge 312. The second corner code component 320 includes a second top edge 321, a second bottom edge 322, and a set of opposing second side edges 323 located between the second top edge 321 and the second bottom edge 322. One of the first side edges 313 is connected to one of the second side edges 323. The first top edge 311 is used to be embedded in a first limiting groove 181 on one side of the slot 160 on the outer wall of the packaging frame 100. The first bottom edge 312 and the second bottom edge 322 are used to be embedded in a second limiting groove 182 on the opposite side of the slot 160 on the outer wall of the packaging frame 100. In this application, a first top edge 311 and a second top edge 321 are provided for embedding in a first limiting groove 181 on one side of the slot 160 on the outer wall of the encapsulation frame 100, and a first bottom edge 312 and a second bottom edge 322 are provided for embedding in a second limiting groove 182 on the opposite side of the slot 160 on the outer wall of the encapsulation frame 100. This ensures that the corner code structure 300 is completely locked in the slot 160 of the encapsulation frame 100, and the first limiting groove 181 and the second limiting groove 182 respectively lock the upper edge and the lower edge of the corner code structure 300 to prevent the corner code structure 300 from falling off.

[0056] In some embodiments, the first top edge 311 has a first boss structure 314. The second top edge 321 has a second boss structure 324. The first boss structure 314 and the second boss structure 324 are respectively used to be embedded in the first limiting groove 181 on the outer side wall of the adjacent encapsulation frame 100. The first boss structure 314 and the second boss structure 324 facilitate the first top edge 311 and the second top edge 321 to be engaged in the first limiting groove 181.

[0057] In some embodiments, the thickness of the first boss structure 314 along the direction perpendicular to the first plane and the thickness of the second boss structure 324 along the direction perpendicular to the second plane are both equal to the width of the first limiting groove 181 on the outer wall of the encapsulation frame 100. It should be noted that the width of the first limiting groove 181 refers to the width perpendicular to the support portion 112. This configuration enables the corner code structure 300 to be stably connected to the encapsulation frame 100 after installation, improving the overall structural compactness, enhancing connection stability, and preventing large gaps between the corner code structure 300 and the encapsulation frame 100.

[0058] In some embodiments, the thickness of the first corner code component 310 and the thickness of the second corner code component 320 are both equal to the width of the second limiting groove 182 on the outer wall of the encapsulation frame 100. It should be noted that the width of the second limiting groove 182 refers to the width perpendicular to the support portion 112. This configuration enables the corner code structure 300 to be stably connected to the encapsulation frame 100 after installation, improving the overall structural compactness, enhancing connection stability, and preventing large gaps between the corner code structure 300 and the encapsulation frame 100.

[0059] In some embodiments, the inner edge of the connection position between the first corner code component 310 and the second corner code component 320 has an edge receiving area 330 for accommodating the edge position of the end face of the package frame 100. For example, if there are burrs at the edge position of the end face of the package frame 100 during cutting, the edge receiving area 330 can accommodate the edge burrs, improving the package fit. See also Figure 1 As shown, the edge receiving area 330 can be recessed inward to form a groove-like structure.

[0060] In some embodiments, the first corner code component 310 extends along the first plane for a length of 3cm to 10cm. The length of the first corner code component 310 extending along the first plane can be set according to actual needs. For example, when the size of the laminate 200 is large, the length of the encapsulation frame 100 is also large. In this case, the length of the first corner code component 310 extending along the first plane can be increased accordingly. When the size of the laminate 200 is small, the length of the encapsulation frame 100 is small. In this case, the length of the first corner code component 310 extending along the first plane can be decreased accordingly to save materials.

[0061] In some embodiments, the second corner code component 320 extends along the second plane for a length of 3cm to 10cm. Similarly, the length of the second corner code component 320 extending along the second plane can be set according to actual needs. For example, when the size of the laminate 200 is large, the length of the encapsulation frame 100 is also large. In this case, the length of the second corner code component 320 extending along the second plane can be increased accordingly. When the size of the laminate 200 is small, the length of the encapsulation frame 100 is small. In this case, the length of the second corner code component 320 extending along the second plane can be decreased accordingly to save materials.

[0062] An embodiment of this application also provides an encapsulation border 100.

[0063] An encapsulation frame 100 has a mounting groove 140 for mounting a laminate 200, and the outer side wall of the encapsulation frame 100 has a slot 160 that can be used to mate with the corner bracket structure 300 of any of the above embodiments.

[0064] In some of these embodiments, see Figure 2 As shown, Figure 2 This is a cross-sectional view of a packaging frame 100 according to an embodiment of the present invention. The packaging frame 100 includes a frame body 110, an abutment member 120, and a limiting member 130. The frame body 110 includes a supporting portion 111, a supporting portion 112, and a mounting portion 113. The supporting portion 111 and the mounting portion 113 are spaced apart. The supporting portion 112 is disposed between the supporting portion 111 and the mounting portion 113 and connects the supporting portion 111 and the mounting portion 113. A supporting surface 101 is formed on the surface of the supporting portion 111 away from the supporting portion 112. The first end and the second end of the supporting portion 111 protrude from the supporting portion 112 along its width direction. The third end and the fourth end of the mounting portion 113 protrude from the supporting portion 112 along its width direction. It should be noted that the width direction of the supporting portion 111 refers to the direction from the edge position to the center position of the laminate 200 after the packaging frame 100 is engaged with the laminate 200.

[0065] In this application, the abutment 120 is located near the first end and connected to the bearing surface 101. The limiting member 130 is connected to the end of the abutment 120 away from the bearing portion 111. The limiting member 130, the abutment 120, and the bearing surface 101 form the aforementioned mounting groove 140. The opening of the mounting groove 140 faces the second end. A retaining groove 160 is formed between the first end, the third end, and the support portion 112, and the outer wall of the support portion 112 forms the bottom surface of the retaining groove 160. The edge of the laminate 200 is encapsulated within the mounting grooves 140 of a plurality of annularly joined encapsulation frames 100. Adjacent encapsulation frames 100 are connected by a corner bracket structure 300. See also... Figure 4 As shown, Figure 4 This is a top view of the encapsulation frame 100 and the corner code structure 300 after they are combined according to an embodiment of the present invention. The first corner code component 310 and the second corner code component 320 are respectively used to be embedded in the slots 160 on the outer side wall of the adjacent encapsulation frame 100.

[0066] In some embodiments, the frame body 110, the abutment 120, and the limiting member 130 are connected in an integral structure.

[0067] In some embodiments, the support portion 112 is generally a plate-like structure, and the support portion 112 has no cavity structure. The cavity-free structure of the support portion 112 can significantly save material.

[0068] In some embodiments, the first end is further connected to a first limiting arm 171 extending toward the mounting portion 113. A first limiting groove 181 is formed between the first limiting arm 171, the first end, and the support portion 112 for the first boss structure 314 or the second boss structure 324 to be embedded.

[0069] In some embodiments, the depth of the first limiting groove 181 is 1cm to 3cm. The first limiting groove 181 has a certain depth to facilitate the engagement of the first boss structure 314 or the second boss structure 324. The depth of the first limiting groove 181 should not be too small, as this can easily cause the first boss structure 314 or the second boss structure 324 to fall off. The depth of the first limiting groove 181 should not be too large, as this can make it difficult for the first boss structure 314 or the second boss structure 324 to be installed into the slot 160.

[0070] In some embodiments, the third end is also connected to a second limiting arm 172 extending toward the support portion 111. A second limiting groove 182 is formed between the second limiting arm 172, the third end, and the support portion 112 for the first bottom edge 312 or the second bottom edge 322 to be embedded.

[0071] In some embodiments, the depth of the second limiting groove 182 is 1cm to 2cm. The second limiting groove 182 has a certain depth to facilitate the locking of the first bottom edge 312 or the second bottom edge 322. The depth of the second limiting groove 182 should not be too small, as this can easily cause the first bottom edge 312 or the second bottom edge 322 to fall off. The depth of the second limiting groove 182 should not be too large, as this can make it difficult for the first bottom edge 312 or the second bottom edge 322 to be installed into the locking groove 160.

[0072] In some embodiments, the width of the first limiting groove 181 is 0.5cm to 1cm.

[0073] In some embodiments, the width of the second limiting groove 182 is 0.8cm to 2cm. It should be noted that the width of the first limiting groove 181 and the width of the second limiting groove 182 refer to the width along the direction perpendicular to the support portion 112.

[0074] In this application, the depth of the second limiting groove 182 is slightly smaller than the depth of the first limiting groove 181, and the width of the second limiting groove 182 is slightly larger than the width of the first limiting groove 181. During installation, the first boss structure 314 or the second boss structure 324 is first installed into the first limiting groove 181, and then force is applied to the first corner code component 310 and the second corner code component 320 of the corner code structure 300 respectively, so that the first bottom edge 312 and the second bottom edge 322 of the first corner code component 310 and the second corner code component 320 are squeezed into the corresponding second limiting groove 182.

[0075] In some embodiments, the photovoltaic module 10 further includes connectors. The first corner code component 310 and the second corner code component 320 are respectively connected to the bottom surface of the slot 160 on the outer wall of the corresponding encapsulation frame 100 via connectors. The connectors can be adhesives, rivets, etc.

[0076] In some embodiments, the first corner code component 310 and the second corner code component 320 are independently connected to the bottom surface of the slot 160 (i.e., part of the outer wall of the support portion 112) on the outer wall of the corresponding encapsulation frame 100 through one or more of the following methods: riveting, screwing, snap-fitting, adhesive connection, and pressing. This arrangement can improve the strength of the connection between the first corner code component 310, the second corner code component 320, and the encapsulation frame 100.

[0077] The frame body 110 of the aforementioned encapsulation frame 100 is provided with a bearing portion 111, a support portion 112, and a mounting portion 113, see [reference]. Figure 3 As shown, Figure 3This is a cross-sectional view of the encapsulation frame 100 and the corner code structure 300 after they are engaged according to an embodiment of the present invention. The edge of the laminate 200 is installed in the mounting groove 140 formed by the limiting member 130, the abutment member 120 and the bearing surface 101. The support part 112 is disposed between the bearing part 111 and the mounting part 113 and is connected to the bearing part 111 and the mounting part 113. Compared with the conventional technology, the present application eliminates the cavity structure, reduces one side of the conventional frame, and effectively ensures the load of the bearing part 111 by moving the support part 112 inward by a certain distance, that is, the first end and the second end of the bearing part 111 protrude from the support part 112 along its width direction. The encapsulation frame 100 of the present application eliminates the cavity and provides the aforementioned corner code structure 300 on the outer side wall of the encapsulation frame 100. On the basis of connecting adjacent encapsulation frames 100, the length of the mounting part 113 can be reduced and the height of the support part 112 can be reduced, reducing material costs and achieving cost reduction and efficiency improvement.

[0078] In some embodiments, the length L1 of the first end protruding from the support portion 112 is less than the length L2 of the second end protruding from the support portion 112.

[0079] In some embodiments, the ratio between the length L1 of the first end protruding from the support portion 112 and the length L2 of the second end protruding from the support portion 112 is 1:2 to 1:4. The value of the ratio between the length L1 of the first end protruding from the support portion 112 and the length L2 of the second end protruding from the support portion 112 includes, but is not limited to, 1:2, 1:3, 1:4 or any range between the two mentioned above.

[0080] In some embodiments, the connection between the support portion 112 and the load-bearing portion 111 is a rounded transition; preferably, the radius R1 of the rounded transition at the connection between the support portion 112 and the load-bearing portion 111 is ≥1.5. The rounded transition at the connection between the support portion 112 and the load-bearing portion 111 can increase the load capacity of the load-bearing portion 111.

[0081] In some embodiments, the connection between the support portion 112 and the mounting portion 113 is a rounded transition. Preferably, the radius of the rounded corner R2 at the connection between the support portion 112 and the mounting portion 113 is ≥ 1.5. This arrangement can increase the stability of the support portion 112 and increase the load on the load-bearing portion 111.

[0082] In some embodiments, the length L3 of the third end protruding from the support portion 112 is less than the length L4 of the fourth end protruding from the support portion 112.

[0083] In some embodiments, the ratio between the length L3 of the third end protruding from the support portion 112 and the length L4 of the fourth end protruding from the support portion 112 is 1:3 to 1:5. The value of the ratio between the length L3 of the third end protruding from the support portion 112 and the length L4 of the fourth end protruding from the support portion 112 includes, but is not limited to, 1:3, 1:4, 1:5 or any two of the foregoing.

[0084] In some embodiments, the length L4 of the fourth end protruding from the support portion 112 is greater than the length L2 of the second end protruding from the support portion 112. This arrangement can increase the supporting strength of the support portion 112 and increase the stability of the entire encapsulation frame 100.

[0085] In some embodiments, the length L3 of the third end protruding from the support portion 112 is equal to the length L1 of the first end protruding from the support portion 112.

[0086] In some embodiments, the maximum distance H1 between the top surface of the limiting member 130 and the bearing surface 101 is not greater than the thickness H2 of the laminate 200, the width W1 of the limiting member 130 is less than the width W2 of the bearing surface 101, the minimum distance H3 between the limiting member 130 and the bearing surface 101 is not less than the thickness H4 of the back panel 201 on the laminate 200, the bearing surface 101 is used to support part of the back panel 201 of the laminate 200, the abutment member 120 is used to abut the end face of the back panel 201 of the laminate 200, the end face of the limiting member 130 is used to abut the end face of the front panel 205 of the laminate 200, and the surface of the limiting member 130 facing the bearing surface 101 is used to press against part of the back panel 201 of the laminate 200.

[0087] The aforementioned encapsulation frame 100 is configured as follows: the maximum distance H1 between the top surface of the limiting member 130 and the bearing surface 101 is not greater than the thickness H2 of the laminate 200; the width W1 of the limiting member 130 is less than the width W2 of the bearing surface 101; and the minimum distance H3 between the limiting member 130 and the bearing surface 101 is not less than the thickness H4 of the back panel 201 on the laminate 200. In this configuration, the encapsulation frame 100 can fit a laminate 200 where the width of the front panel 205 is less than the width of the back panel 201. The abutment member 120 abuts against the end face of the back panel 201 of the laminate 200, and the end face of the limiting member 130 abuts against the front panel of the laminate 200. The end face of the limiting member 130, facing the bearing surface 101, presses against a portion of the back panel 201 of the laminate 200. This arrangement ensures that the front panel 205 of the laminate 200 is not higher than the limiting member 130 after encapsulation. When the photovoltaic module 10 is in use, the junction between the front panel 205 and the limiting member 130 is not prone to dust or rain accumulation. Even if a small amount of dust accumulates, it can be quickly and thoroughly cleaned off the front panel 205 by rainwater and will not remain on the front panel 205. This achieves the purpose of reducing dust accumulation and hot spots, while increasing the power generation of the photovoltaic module 10, reducing the frequency of module cleaning to a certain extent, and ensuring returns.

[0088] In some embodiments, the limiting member 130 is parallel to the bearing surface 101. Preferably, the outer surface, i.e., the top surface, of the limiting member 130 is a smooth surface or a sloping surface. When the outer surface of the limiting member 130 is a sloping surface, the height of the outer surface of the limiting member 130 from the bearing surface 101 gradually decreases from the side away from the abutment member 120 to the side closer to the abutment member 120, forming a sloping surface. This allows a small amount of dust accumulated on the front panel 205 to be washed away by rainwater, achieving the purpose of preventing dust accumulation.

[0089] In some embodiments, the maximum distance H1 between the top surface of the limiting member 130 and the bearing surface 101 is less than the thickness H2 of the laminate 200, and the distance between the end of the top surface of the limiting member 130 away from the abutment 120 and the bearing surface 101 is greater than the distance between the end of the top surface of the limiting member 130 closer to the abutment 120 and the bearing surface 101. It should be noted that, see [link to relevant documentation] Figure 1 As shown, the maximum distance H1 between the top surface of the limiting member 130 and the bearing surface 101 refers to the maximum distance between the outer surface of the limiting member 130 and the bearing surface 101.

[0090] In some embodiments, the maximum distance H1 between the top surface of the limiting member 130 and the bearing surface 101 is 0-3 mm smaller than the thickness H2 of the laminate 200. This arrangement allows a small amount of dust accumulated on the front panel 205 to be washed away by rainwater, thus preventing dust accumulation.

[0091] In some embodiments, the limiting member 130 includes a limiting base 131 connected to the abutment member 120 and a limiting protrusion 150 connected to the limiting base 131. The minimum distance H5 between the limiting protrusion 150 and the bearing surface 101 is not less than the thickness H4 of the back panel 201 on the laminate 200. In this case, the minimum distance H3 between the limiting member 130 and the bearing surface 101 can be greater than the minimum distance H5 between the limiting protrusion 150 and the bearing surface 101.

[0092] In some embodiments, the minimum distance H5 between the limiting protrusion 150 and the bearing surface 101 is 0.6mm to 1.5mm larger than the thickness H4 of the back panel 201 on the laminate 200. This arrangement allows the back panel 201 of the laminate 200 to have a certain margin when moving in the area between the limiting protrusion 150 and the bearing surface 101, ensuring that the back panel 201 can move to a certain extent during encapsulation.

[0093] In some embodiments, the width W1 of the limiting member 130 is 2mm to 7mm. The value of the width W1 of the limiting member 130 includes, but is not limited to: 2mm, 3mm, 4mm, 5mm, 6mm, 7mm or any range between the two mentioned above.

[0094] In some embodiments, the width W1 of the limiting member 130 is equal to the distance W3 between the edge of the back panel 201 and the edge of the front panel 205 on the laminate 200. See also Figure 5 As shown, Figure 5 This is a cross-sectional view of the laminate 200 according to an embodiment of the present invention. The edge of the back panel 201 of the laminate 200 protrudes beyond the edge of the front panel 205, and the distance by which the edge of the back panel 201 protrudes beyond the edge of the front panel 205 is W3. This configuration ensures that, after encapsulation, the edge of the laminate 200 is completely engaged within the mounting groove 140 on the encapsulation frame 100, achieving a state where the abutment 120 abuts against the end face of the back panel 201 of the laminate 200, and the limiting member 130 abuts against the end face of the front panel 205 of the laminate 200. During encapsulation, this minimizes the risk of the front panel 205 shattering.

[0095] It should be noted that when the limiting member 130 includes the limiting protrusion 150, the width W1 of the limiting member 130 refers to the width of the limiting base 131. The width W1 of the limiting base 131 is its dimension along the width direction of the package edge.

[0096] In some embodiments, the width W1 of the limiting member 130 is smaller than the width W2 of the bearing surface 101. By setting the width of the limiting member 130 to be smaller than the width of the bearing surface 101, the laminations 200 with different widths for the front panel 205 and the back panel 201 are encapsulated.

[0097] In some embodiments, the limiting protrusion 150 is located at the end of the limiting member 130 away from the abutment member 120. The limiting protrusion 150, located at the end away from the abutment member 120, can both press against the protruding part of the back panel 201 and abut against the end face of the front panel 205, thereby improving the sealing fit, reducing the gap between the frame and the laminate 200, and reducing dust accumulation.

[0098] In some embodiments, the limiting protrusion 150 includes a connecting portion 151 and a bent portion 152. The connecting portion 151 and the bent portion 152 are generally bent structures. For example, see... Figure 1 As shown, the bent structure is approximately "J" shaped. Connecting portion 151 is connected to limiting base 131. Bending portion 152 is connected to connecting portion 151 and extends towards the bottom surface of mounting groove 140. An auxiliary receiving area 153 for accommodating overflowing adhesive is formed between bending portion 152, connecting portion 151, and limiting base 131. Connecting portion 151 and part of limiting base 131 together abut against the end face of front panel 205 of laminate 200, and bending portion 152 abuts against part of front panel 205 of laminate 200. Bending portion 152 can limit front panel 205, and the outer side of bending portion 152 away from abutting member 120 can be used to abut against the end face of front panel 205, thus minimizing the risk of front panel 205 shattering during encapsulation.

[0099] In some embodiments, the length of the bend 152 extending toward the bottom surface of the mounting groove 140 is not greater than the distance W3 between the edge of the back panel 201 and the edge of the front panel 205 on the laminate 200.

[0100] In some embodiments, the extending direction of the bent portion 152 and the limiting base 131 are both parallel to the bearing surface 101. See also Figure 2 As shown, the surface of the bent portion 152 near the bearing surface 101 is preferably designed as a flat surface, so that the bent portion 152 and the back panel 201 can have a larger contact area, which can play a role in distributing the force during mechanical load testing.

[0101] In some embodiments, the outer surface of the connection position between the connecting portion 151 and the bending portion 152 has a curved chamfered structure. The design of the outer surface of the connection position between the connecting portion 151 and the bending portion 152 with a curved chamfered structure makes it easier for the back panel 201 to be inserted into the mounting groove 140, thus improving installation convenience.

[0102] In some embodiments, the connecting portion 151 and the limiting base portion 131 have an included angle of 80° to 110°.

[0103] Preferably, the connecting portion 151 is perpendicular to the limiting base 131. The perpendicularity between the connecting portion 151 and the limiting base 131 can increase the contact area between the connecting portion 151 and the end face of the front panel 205, reduce the gap between them, and reduce dust accumulation.

[0104] In some embodiments, the surface of the abutment 120 located within the mounting groove 140 has an abutment protrusion 121. The abutment protrusion 121 is close to the bearing surface 101 and is used to abut against at least a portion of the end face of the back panel 201 of the fixed laminate 200.

[0105] In some embodiments, the surface of the abutment 120 located within the mounting groove 140 has a pressing protrusion 122. The pressing protrusion 122 is close to the retainer 130 and is used to assist adhesive overflow to the front panel 205 of the laminate 200.

[0106] In some embodiments, the bearing surface 101 has a plurality of adhesive overflow grooves 102. The adhesive overflow grooves 102 can hold a portion of the adhesive, thereby improving its adhesive strength and enhancing the connection between the back panel 201 and the bearing surface 101.

[0107] In some embodiments, the surface of the bearing surface 101 is generally planar, which can increase the contact area between the back panel 201 and the bearing surface 101 and improve the connection between the back panel 201 and the bearing surface 101.

[0108] In some embodiments, the inner wall of the overflow groove 102 gradually narrows from the bottom surface of the groove to the opening. This design enables the bonded parts after the adhesive has cured to form a structure that is larger inside and smaller outside, making it difficult for the bonded parts to detach from the overflow groove 102 and improving the connection between the back panel 201 and the bearing surface 101.

[0109] In some embodiments, the shape of the overflow groove 102 can be a regular shape or an irregular shape, such as a square groove, a circular groove, etc., and no specific limitation is made here.

[0110] In some embodiments, the number of slots in the overflow groove 102 is determined according to the width W2 of the bearing surface 101.

[0111] In some embodiments, the frame body 110 is a metal frame made of metal or alloy material, or a composite material frame made of composite material.

[0112] Preferably, the frame body 110 is a composite material frame made of composite materials. The materials of the composite material frame include polyurethane, glass fiber, etc., which have insulating properties. Therefore, the creepage distance of the photovoltaic module 10 using the composite material frame can theoretically be zero. To ensure that the battery cells 203 are not obstructed and considering the sealing of the encapsulant film, the size of the front panel 205 of the photovoltaic module 10 using the composite material frame in this application can be reduced. Compared with photovoltaic modules 10 of conventional technology, this application can effectively reduce the overall structural size. Here, creepage distance refers to the safe distance between the frame and charged bodies such as battery strings.

[0113] One embodiment of this application provides a border combination.

[0114] A frame assembly includes a corner code structure 300 and an encapsulation frame 100. A first corner code component 310 and a second corner code component 320 can be respectively embedded in a slot 160 on the outer side wall of an adjacent encapsulation frame 100 to achieve connection between adjacent encapsulation frames.

[0115] One embodiment of this application provides a photovoltaic module 10.

[0116] The photovoltaic module 10 includes a laminate 200 and a frame assembly.

[0117] In some embodiments, a photovoltaic module 10 includes a laminate 200, an encapsulation frame 100, and a corner code structure 300 as described in any of the above embodiments. The laminate 200 includes a back panel 201, a back adhesive film 202, a cell 203, a front adhesive film 204, and a front panel 205, which are stacked sequentially. The cell 203 includes a plurality of cells or a plurality of cell strings connected together.

[0118] In some of these embodiments, see Figure 6 As shown, Figure 6 This is a cross-sectional view of the encapsulation frame 100, corner code structure 300, and laminate 200 after assembly according to an embodiment of the present invention. The edges of the back panel 201 protrude beyond the edges of the front panel 205, and the distance W3 between the edges of the back panel 201 and the front panel 205 on the laminate 200 is 1 / 3. The laminate 200 is encapsulated by the encapsulation frame 100. Part of the back panel 201 of the laminate 200 is located on the bearing surface 101. The end face of the back panel 201 of the laminate 200 can abut against the abutment member 120. The end face of the front panel 205 of the laminate 200 abuts against the end face of the limiting member 130. Part of the back panel 201 of the laminate 200 abuts against the surface of the limiting member 130 facing the bearing surface 101.

[0119] In some embodiments, when the limiting protrusion 150 is connected to the limiting member 130, the limiting protrusion 150 abuts against the back panel 201, specifically, the bent portion 152 abuts against the back panel 201. The connecting portion 151 and part of the limiting base 131 are used together to abut against the end face of the front panel 205 of the laminate 200, and the bent portion 152 is used to abut against part of the back panel 201 of the laminate 200. The bent portion 152 can limit the back panel 201, and the outer side of the bent portion 152 away from the abutting member 120 can be used to abut against the end face of the front panel 205, thus minimizing the risk of the front panel 205 breaking during packaging.

[0120] In some embodiments, the number of encapsulation borders 100 can be multiple.

[0121] In some embodiments, the lengths of the encapsulation border 100 may be equal or unequal. For example, the encapsulation border 100 may include a long border and a short border to fit the long and short sides of the laminate 200, respectively.

[0122] In some embodiments, the length of the encapsulation border 100 can be set according to the length or width of the laminate 200, and no specific limitation is made here.

[0123] In some embodiments, the adhesive used in the mounting groove 140 during encapsulation can be the glue used in the photovoltaic field, without specific limitations.

[0124] In some embodiments, the front panel 205 and the back panel 201 described above can be independently selected from photovoltaic glass panels.

[0125] In summary, compared with traditional technologies, the encapsulation border 100 of this application has the following beneficial effects:

[0126] (1) Cost reduction: The material of the frame body 110 of this application is reduced by one side wall, and the size of other side walls such as the support part 112 and the mounting part 113 can be reduced. On the basis of structural optimization to ensure load, the material of non-critical parts is effectively reduced, thereby reducing the cost of frame material. Furthermore, the encapsulation frame 100 of this application can eliminate the cavity structure and eliminate the need to use corner brackets, thereby reducing material cost.

[0127] (2) Airborne reliability: By using the limiting member 130 or the limiting protrusion 150 to restrain the back panel 201 of the laminate 200, the airborne load strength can be guaranteed to the maximum extent.

[0128] (3) Dust prevention: The encapsulation frame 100 of this application is adapted to the laminate 200 when the widths of the front panel 205 and the back panel 201 are different. The maximum height of the bearing surface 101 of the limiting member 130 is not higher than that of the front panel 205. Therefore, a small amount of dust on the front panel 205 can be more easily washed away by rainwater, thus achieving the purpose of preventing dust accumulation.

[0129] (4) Aesthetically pleasing appearance: The composite material frame of this application is preferably made of composite material, which can be made of a variety of colors such as black and dark blue, forming the same color effect as the battery 203, and has a better visual effect. Since this application reduces the size of the limiting member 130 and the abutment member 120, even if a metal frame made of metal or alloy material is used, such as an aluminum frame, visual comfort can be improved.

[0130] (5) The encapsulation frame 100 has various assembly forms: The encapsulation frame 100 of this application eliminates the cavity of the frame, so the long and short frames can be connected by an integrated folding method, and the two encapsulation frames 100 at the beginning and end are connected by a buckle to achieve a closed loop connection.

[0131] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0132] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0133] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
