Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a mounting block, a packaging frame, a frame assembly, and a photovoltaic module. Background Technology

[0002] When photovoltaic (PV) modules are installed outdoors, clamps are used to secure the frame. Traditional clamps are typically designed based on conventional frame structures. Conventional frames include an A-side for bonding the laminate, which is higher than the front glass. The clamp is installed directly on the A-side of the frame. In traditional technology, the clamp is too close to the front glass of the laminate during installation, making it prone to bursting during outdoor use or airborne testing. Although there are solutions to mitigate the risk of bursting by adding cushioning pads at the contact point between the clamp and the front glass, these pads are susceptible to damage, aging, and detachment, still posing a certain risk. Furthermore, traditional clamps are tall, require a lot of material, and are costly. Their securing strength to the PV modules is also insufficient, making them prone to loosening in strong winds, causing the PV modules to sway. Utility Model Content

[0060] This application provides an installation clamping block 300 to solve at least one of the following technical problems in conventional clamping blocks when installing photovoltaic modules: (1) The clamping block is too close to the front glass of the laminate, making it prone to breakage during outdoor use or airborne testing. (2) The clamping block is tall, requires a lot of material, and has high material costs. (3) The clamping block does not provide sufficient fixing strength to the photovoltaic module, making it prone to loosening in strong winds, causing the photovoltaic module to sway easily. The installation clamping block 300 will be described below with reference to the accompanying drawings.

[0061] The mounting block 300 provided in this application embodiment is exemplary; please refer to [link to example]. Figure 1 As shown, Figure 1 This is a schematic diagram of the mounting block 300 provided in an embodiment of this application. The mounting block 300 of this application can be used for outdoor installation of photovoltaic modules 10.

[0062] To more clearly illustrate the structure of the mounting block 300, the mounting block 300 will be described below in conjunction with the accompanying drawings.

[0063] For example, please refer to Figure 1 As shown, a mounting block 300 includes a block base 340 and a locking part 330. The locking part 330 is connected to the block base 340. See also... Figure 2As shown, the locking part 330 is used to insert into the slot 160 on the outer wall of the encapsulation frame 100. The pressure block base 340 is used to fix it to the mounting base surface by fastener 400. The mounting base surface can be the ground, table, roof, or other locations in the scenario where the photovoltaic module 10 needs to be installed.

[0064] The aforementioned mounting block 300 can be used to install and fix the encapsulation frame 100. The mounting block 300 of this application does not require pressing and fixing the A-side of the traditional frame. Instead, the locking part 330 is inserted into the slot 160 on the outer wall of the encapsulation frame 100, and the base 340 of the block is fixedly connected to the mounting surface, such as the ground, by fasteners 400. It fixes the encapsulation frame 100 from the outer side, adapting to both frames with cavities and encapsulation frames 100 without cavities. The mounting block 300 of this utility model has a simple structure, requires less material, reduces costs, and improves the firmness of the frame fixation.

[0065] In some embodiments, the bottom surface of the pressure block base 340 has an uneven structure for increasing friction.

[0066] In some embodiments, the base 340 of the pressure block is provided with a mounting hole 301 adapted to the fastener 400. The mounting hole 301 is used for the fastener 400 to be inserted to connect with the mounting base.

[0067] In some embodiments, the pressure block base 340 includes a first base 310 and a second base 320 connected together. The second base 320 is connected to the locking portion 330. See also Figure 3 As shown, one end of the locking portion 330 protrudes from the second base 320 and is spaced from the first base 310. This space is for the second limiting arm 172, which forms the second limiting groove 182 described below, to be fitted into. See also Figure 4 As shown, the first base 310 or the second base 320 is used to be fixedly connected to the mounting base by fasteners 400.

[0068] In some embodiments, the bottom surface of the first base 310 is a rough surface that can increase friction, for example, the bottom surface of the first base 310 has an uneven structure.

[0069] In some of these embodiments, see Figure 5 As shown, the two ends of the locking portion 330 protrude from the second base 320. See also Figure 6 As shown, one end of the locking part 330 is used to be embedded in the first limiting groove 181 on one side of the card slot 160, and the other end is used to be embedded in the second limiting groove 182 on the other side of the card slot 160.

[0070] In some of these embodiments, see Figure 7As shown, one end of the locking portion 330 has a locking boss structure 331. See also Figure 8 As shown, the locking boss structure 331 is used to be embedded in the second limiting groove 182 on the other side of the card slot 160.

[0071] In some of these embodiments, see Figure 9 As shown, one end of the locking portion 330 has a locking engagement portion 332. See also Figure 10 as well as Figure 12 As shown, the locking part 330 has an end of the locking engagement part 332 for being embedded in the locking groove 173 on the first end of the support part 111 of the frame body 110.

[0072] In some of these embodiments, see Figure 11 As shown, at least a portion of the surface of the locking engagement portion 332 has an uneven structure. The uneven structure of the locking engagement portion 332 can increase the friction between the locking engagement portion 332 and the inner wall of the locking groove 173, reducing the risk of the locking engagement portion 332 disengaging from the locking groove 173.

[0073] In some embodiments, at least a portion of the inner wall of the locking groove 173 has an uneven structure. The uneven structure of the inner wall of the locking groove 173 can increase the friction between the locking engagement portion 332 and the inner wall of the locking groove 173, reducing the risk of the locking engagement portion 332 disengaging from the locking groove 173.

[0074] An embodiment of this application also provides an encapsulation border 100.

[0075] An encapsulation frame 100 has a mounting groove 140 for mounting a laminate 200. The outer side wall of the encapsulation frame 100 has a slot 160 for mounting a mounting block 300, at least a portion of the locking portion 330 of the mounting block 300 is engaged in the slot 160.

[0076] In some of these embodiments, see Figure 2As shown, the encapsulation frame 100 includes a frame body 110, an abutment 120, and a limiting member 130. The frame body 110 includes a carrier portion 111, a support portion 112, and a mounting portion 113. The carrier portion 111 and the mounting portion 113 are spaced apart, and the support portion 112 is disposed between and connected to the carrier portion 111 and the mounting portion 113. A carrier surface 101 is formed on the surface of the carrier portion 111 away from the support portion 112. A first end of the carrier portion 111 protrudes from the support portion 112 along its width direction. A third end of the mounting portion 113 protrudes from the support portion 112 along its width direction. The abutment 120 is connected to the first end. The limiting member 130 is connected to the end of the abutment 120 away from the carrier portion 111. The limiting member 130, the abutment 120, and the carrier surface 101 form a mounting groove 140. The groove opening of the mounting groove 140 faces the second end of the support portion 111, and a slot 160 is formed between the first end, the third end, and the support portion 112. It should be noted that the width direction of the support portion 111 mentioned above refers to the direction from the edge position of the laminate 200 to its central position after the encapsulation frame 100 and the laminate 200 are engaged.

[0077] In some embodiments, the frame body 110, the abutment 120, and the limiting member 130 are connected in an integral structure.

[0078] In some embodiments, the support portion 112 is generally a plate-like structure and has no cavity structure.

[0079] In some of these embodiments, see Figure 4 , Figure 6 As shown, the first end is also 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 one end of the locking portion 330 to be fitted into.

[0080] 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 one end of the locking part 330. The depth of the first limiting groove 181 should not be too small, as this can easily cause one end of the locking part 330 to detach. The depth of the first limiting groove 181 should not be too large, as this can make it difficult for one end of the locking part 330 to be installed into the slot 160.

[0081] In some of these embodiments, see Figure 8As shown, the third end is also connected to a second limiting arm 172 extending toward the bearing 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 other end of the locking portion 330 to be embedded.

[0082] 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 other end of the locking part 330. The depth of the second limiting groove 182 should not be too small, as this can easily cause the other end of the locking part 330 to fall off. The depth of the second limiting groove 182 should not be too large, as this can make it difficult for the other end of the locking part 330 to be installed into the slot 160.

[0083] In some embodiments, the width of the first limiting groove 181 is 0.5cm to 1cm.

[0084] 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.

[0085] 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, one end of the locking part 330 is first installed into the first limiting groove 181, and then force is applied to the other end of the locking part 330 to press the other end of the locking part 330 into the second limiting groove 182.

[0086] The aforementioned encapsulation frame 100 has a frame body 110 with a bearing portion 111, a support portion 112, and a mounting portion 113. 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 portion 112 is located between and connected to the bearing portion 111 and the mounting portion 113. Compared with conventional technology, this application eliminates the cavity structure, reduces one side of the conventional frame, and effectively ensures the load of the bearing portion 111 by moving the support portion 112 inward by a certain distance, that is, the first end and the second end of the bearing portion 111 protrude from the support portion 112 along its width direction. The encapsulation frame 100 of this application can eliminate the cavity, which can reduce the length of the mounting portion 113 and the height of the support portion 112, reduce material costs, and achieve cost reduction and efficiency improvement. The aforementioned mounting block 300 is provided on the outer wall of the encapsulation frame 100 to fix the encapsulation frame 100.

[0087] In some of these embodiments, see Figure 4 , 6 As shown, 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.

[0088] In some of these embodiments, please refer again. Figure 4 , 6 As shown, 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 two of the foregoing.

[0089] In some of these embodiments, see Figure 4 , 6 As shown, 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 on the load-bearing portion 111.

[0090] In some of these embodiments, see Figure 4 , 6 As shown, the connection between the support portion 112 and the mounting portion 113 is a rounded transition. Preferably, the radius R2 of the rounded transition at the connection between the support portion 112 and the mounting portion 113 is ≥ 1.5. This configuration can increase the stability of the support portion 112 and increase the load on the load-bearing portion 111.

[0091] In some of these embodiments, see Figure 4 , 6 As shown, 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.

[0092] In some of these embodiments, see Figure 4 , 6 As shown, the ratio between the length L3 protruding from the support portion 112 at the third end and the length L4 protruding from the support portion 112 at the fourth end is 1:3 to 1:5. The value of the ratio between the length L3 protruding from the support portion 112 at the third end and the length L4 protruding from the support portion 112 at the fourth end includes, but is not limited to: 1:3, 1:4, 1:5 or any range between the two mentioned above.

[0093] In some of these embodiments, see Figure 4 , 6As shown, 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.

[0094] 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.

[0095] In some embodiments, the support portion 111 may move toward the second end, in which case the first and second ends of the support portion 111 protrude from the support portion, and the third and fourth ends of the mounting portion 113 protrude from the support portion. Preferably, see Figure 10 As shown, the end face of the second end of the bearing portion 111 along its width direction and the end face of the fourth end of the mounting portion 113 along its width direction are flush with the plane where the support portion 112 is located. The bearing portion 111, the support portion 112, and the mounting portion 113 form the aforementioned slot 160, and the locking portion 330 is located within the slot 160, with its two ends abutting against the bearing portion 111 and the mounting portion 113, respectively. When the bearing portion 111, the support portion 112, and the mounting portion 113 form the aforementioned slot 160, the slot 160 is located on the outer wall of the frame body 110 away from the laminate 200.

[0096] In some of these embodiments, see Figure 10 as well as Figure 12 As shown, a locking groove 173 is provided at the first end of the bearing portion 111, with the opening of the locking groove 173 facing towards or away from the support portion 112. The locking groove 173 is used to mate with the locking engagement portion 332. The locking portion 330 is bent at one end facing the bearing portion 111 to form the locking engagement portion 332, see [reference]. Figure 10 As shown, the opening of the locking groove 173 faces the support portion 112. The locking engagement portion 332 extends away from the support portion 112 and can engage with the locking groove 173.

[0097] See Figure 12 As shown, the opening of the locking groove 173 faces away from the support portion 112. The locking engagement portion 332 extends toward the support portion 112, and the locking engagement portion 332 can cooperate with the locking groove 173. That is, the extending direction of the locking engagement portion 332 can be adapted to the orientation of the opening of the locking groove 173.

[0098] Preferably, at least a portion of the inner wall of the locking groove 173 and at least a portion of the locking engagement portion 332 are provided with a concave-convex structure.

[0099] It should be noted that the concave-convex structures in the above embodiments include structures such as serrations, protrusions, and grooves, as long as they can increase friction.

[0100] In some of these embodiments, see Figure 10 as well as Figure 12 As shown, when the end face of the second end of the bearing portion 111 along its width direction and the end face of the fourth end of the mounting portion 113 along its width direction are flush with the plane where the support portion 112 is located, the width W4 of the mounting portion 113 is greater than the width W2 of the bearing surface 101, that is, the third end of the mounting portion 113 protrudes beyond the first end. See [reference needed]. Figure 10 As shown, the first base 310 can be directly fitted onto the third end of the mounting portion 113, and the fastener 400 passes through the mounting hole 301 and the third end before connecting to the mounting surface. In another embodiment, see... Figure 12 As shown, the first base 310 and the second base 320 can be connected as a whole, for example, in the form of a long strip. In this case, the first base 310 and the second base 320 are completely attached to the third end. The fastener 400 passes through the mounting hole 301 and through the third end and is then connected to the mounting surface.

[0101] In some of these embodiments, see Figure 10 As shown, the length L5 of the third end of the mounting portion 113 protruding from the first end is 1 / 3W4 to 2 / 3W4. Preferably, the length L5 of the third end of the mounting portion 113 protruding from the first end is 1 / 2W4.

[0102] In some of these embodiments, see Figure 10 , 12 As shown, the connection between the support portion 112 and the load-bearing portion 111 is a rounded transition; preferably, the radius of the rounded corner R3 of the rounded transition between the support portion 112 and the load-bearing portion 111 is ≥3. The rounded transition at the connection between the support portion 112 and the load-bearing portion 111 can increase the load on the load-bearing portion 111.

[0103] In some of these embodiments, see Figure 10 , 12 As shown, the connection between the support portion 112 and the mounting portion 113 is a rounded transition. Preferably, the radius of the rounded corner R4 at the connection between the support portion 112 and the mounting portion 113 is ≥3. This arrangement can increase the stability of the support portion 112 and increase the load on the load-bearing portion 111.

[0104] 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, 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. The bearing surface 101 is used to support a portion of the back panel 201 of the laminate 200, the abutting member 120 is used to abut against the end face of the back panel 201 of the laminate 200, the end face of the limiting member 130 is used to abut against 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 a portion of the back panel 201 of the laminate 200. It should be noted that the width W1 of the limiting member 130 refers to the distance that the limiting member 130 extends from the edge of the laminate 200 to its center after the limiting member 130 is assembled with the laminate 200. Similarly, the width W2 of the bearing surface 101 refers to the distance that the bearing surface 101 extends from the edge of the laminate 200 to its center after the limiting member 130 and the laminate 200 are assembled.

[0105] 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 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 smaller 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 end face of the front panel 205 of the laminate 200. The surface 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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 of movement within 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. After the back panel 201 is installed, it is filled and sealed with adhesive.

[0111] 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.

[0112] 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. Please refer again. Figure 5 As shown, Figure 5This 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 laminate 200 is completely secured to the frame, with the abutment 120 abutting against the end face of the back panel 201 of the laminate 200 and the limiting member 130 abutting 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.

[0113] 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 border 100.

[0114] 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 W1 of the limiting member 130 to be smaller than the width W2 of the bearing surface 101, the laminations 200 with different widths for the front panel 205 and the back panel 201 are encapsulated.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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 close to 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] In some embodiments, the number of slots in the overflow groove 102 is determined according to the width W2 of the bearing surface 101.

[0127] 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.

[0128] 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 a composite material frame can theoretically be zero. To ensure that the 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 the cell strings 203.

[0129] One embodiment of this application provides a border combination.

[0130] A frame assembly includes a mounting block 300 and an encapsulation frame 100. A locking portion 330 is used to insert into a slot 160 on the outer side wall of the encapsulation frame 100, and a base 340 of the mounting block is used to fix it to the mounting base surface by a fastener 400.

[0131] In some embodiments, the fastener 400 can be a bolt, screw, or other structural component, as long as it enables a fixed connection to the bottom surface of the base 340 of the pressure block under working conditions. The fastener 400 is used to fix the photovoltaic module.

[0132] One embodiment of this application provides a photovoltaic module 10.

[0133] The photovoltaic module 10 includes a laminate 200 and a frame assembly, wherein the laminate 200 is encapsulated in multiple encapsulation frames 100.

[0134] In some embodiments, a photovoltaic module 10 includes a laminate 200 and a frame assembly. The frame assembly includes an encapsulation frame 100 and a mounting block 300. 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 stacked sequentially. The laminate 200 is encapsulated within mounting grooves 140 of a plurality of annularly spliced ​​encapsulation frames 100, and a locking part 330 is inserted into a slot 160 on the outer wall of the encapsulation frame 100. The cell 203 includes a plurality of cells or a plurality of cell strings connected together.

[0135] In some of these embodiments, see Figure 13 As shown, Figure 13 This is a cross-sectional view of a laminate 200 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. The laminate 200 is encapsulated by an 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.

[0136] 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.

[0137] In some embodiments, the number of encapsulation borders 100 can be multiple.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] In some embodiments, the front panel 205 and the back panel 201 described above can be independently selected from photovoltaic glass panels.

[0142] Compared with traditional technologies, the mounting block 300 of this application has the following advantages:

[0143] (1) Easy to install: The mounting block 300 is installed in the slot 160 on the outer side of the frame, making it convenient for outdoor operation.

[0144] (2) Low risk of breakage: The installation block 300 does not contact the front glass of the laminate 200, thus avoiding the risk of the front glass breaking.

[0145] (3) Low cost: The installation block 300 has a simple and practical design, uses less material, and has a low cost.

[0146] (4) Easy to process: There is no need to consider the A-side curvature of conventional pressure blocks. The overall design and dimensional accuracy of the pressure block 300 in this application are easy to process.

[0147] (5) Strong anti-slip properties: The bottom surface of the mounting block is roughened to prevent slipping.

[0148] 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.
