[0003] The present application relates to the technical field of photovoltaic module structures, and in particular to a pressing block and a photovoltaic device. Background Art

[0004] Solar energy, currently one of the most promising renewable energy sources, has been widely used in recent years, with photovoltaic power generation being one of the most important applications. As shown in Figure 1, a photovoltaic device comprises a mounting platform, multiple battery modules, and multiple pressing blocks. Two adjacent battery modules are joined and secured to the mounting platform via the pressing blocks. Each battery module comprises a laminate and a frame assembly surrounding the laminate. When joining the first battery module 200 and the second battery module 300, the pressing block 100 is first engaged with the first battery module 200. Next, the pressing block 100 is mounted on the mounting platform 400 using fasteners 500. At this point, the fasteners 500 are not tightened, allowing for play between the pressing block 100 and the mounting platform 400. Finally, the second battery module 300 is tilted to a predetermined angle so that it engages the pressing block 100. Finally, the fasteners 500 are tightened to secure the pressing block 100 and the mounting platform 400, completing the connection between the first battery module 200 and the second battery module 300. The existing pressing block structure requires that the second battery module 300 must be tilted as a whole to achieve the snap connection when it is snapped into place with the second battery module 300. This makes installation of the pressing block 100 and the second battery module 300 inconvenient and inefficient.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] To facilitate understanding of this embodiment, this embodiment is described in detail below with reference to the accompanying drawings.

[0036] The present application provides a pressing block 100 for splicing a first battery module 200 and a second battery module 300. As shown in Figures 2 to 4, the pressing block 100 includes a main body 110, a first clamping member 120 and a second clamping member 130. The first clamping member 120 is arranged on the main body 110 and is used to clamp with the first battery module 200; the second clamping member 130 is arranged at both ends of the main body 110 along a first direction in a one-to-one correspondence with the first clamping member 120, and the second clamping member 130 extends from the main body 110 toward a side away from the first clamping member 120, wherein the first direction is the arrangement direction of the first battery module 200 and the second battery module 300; the second clamping member 130 is elastic, so that when the second battery module 300 approaches the pressing block 100 along the first direction, the second clamping member 130 can be elastically deformed along the second direction to clamp the main body 110 and the second battery module 300, wherein the second direction is the thickness direction of the pressing block 100.

[0037] The above-mentioned pressing block 100 is provided with a first clamping member 120 on one side of the pressing block 100 along the first direction, thereby achieving connection between the pressing block 100 and the first battery module 200. A second clamping member 130 is provided on the other side of the pressing block 100 along the first direction, and the second clamping member 130 extends from the body 110 in a direction away from the first clamping member 120. Because the second clamping member 130 is elastic, when the pressing block 100 is connected to the second battery module 300, it is only necessary to push the second battery module 300 toward the pressing block 100. The second clamping member 130 can be elastically deformed in the second direction under the action of external force, thereby being snapped into the second battery module 300, thereby achieving the snap connection between the pressing block 100 and the second battery module 300. The pressing block 100 provided in the present application can complete the snap connection of the first battery module 200 and the second battery module 300 by simply pushing the second battery module 300, which reduces the difficulty of installation, increases the installation speed, and improves the installation efficiency.

[0038] In some embodiments, as shown in FIG. 2 , the body 110 is a hollow rectangular parallelepiped structure.

[0039] In some embodiments, a mating piece that cooperates with the second latch 130 is provided on the second battery module 300 , and the mating piece is snapped into the second latch 130 on the body 110 .

[0040] In some embodiments, as shown in Figures 2 to 5, the second latch 130 includes a first latch 131 and a second latch 132 arranged along the second direction. The first latch 131 and the second latch 132 are used to snap into the second slot 312 on the second battery module 300. By providing the first latch 131 and the second latch 132, when the second battery module 300 moves toward the pressing block 100, the first latch 131 and the second latch 132 can both undergo elastic deformation along the second direction, thereby snapping the first latch 131 and the second latch 132 into the second slot 312 of the second battery module 300.

[0041] In some embodiments, as shown in Figures 2 to 5, the first latch 131 extends from the outer wall 311 of the body 110 along a first direction away from the first latch 120, and its end away from the body 110 extends along a second direction away from the second latch 132. The first latch 131 is L-shaped, extending from the outer wall 311 of the body 110 along the first direction away from the first latch 120, then bending its end and extending along the second direction away from the second latch 132. When the first latch 131 and the second latch slot 312 are engaged, the first latch 131 abuts against one wall of the second latch slot 312.

[0042] In some embodiments, as shown in Figures 2 to 5, the second latch 132 extends from the outer wall 311 of the body 110 along a first direction away from the first latch 120, and its end away from the body 110 extends along a second direction away from the first latch 131. The second latch 132 is L-shaped, and the structures of the second latch 132 and the first latch 131 are symmetrical. The second latch 132 extends from the outer wall 311 of the body 110 along the first direction away from the first latch 120, then bends and extends along the second direction away from the first latch 131. When the second latch 132 and the second latch slot 312 are engaged, the second latch 132 abuts against the other wall of the second latch slot 312.

[0043] In some embodiments, as shown in Figures 2 to 5, the pressing block 100 further includes a blocking member 140 disposed on the body 110. The blocking member 140 is configured to abut against the side wall 311 of the second battery module 300 after the second clamping member 130 and the second battery module 300 are engaged, thereby limiting movement of the second battery module 300 along the second direction. By providing the blocking member 140, when the second clamping member 130 and the second battery module 300 are engaged, the blocking member 140 can abut against the side wall 311 of the second battery module 300, thereby limiting movement of the second battery module 300 along the second direction.

[0044] In some embodiments, as shown in Figures 2 to 5 , a side surface of the blocking member 140 along the first direction, which is close to the second battery module, is configured to completely mate with the side wall 311 of the second battery module 300. This side surface of the blocking member 140 along the first direction completely mates with the side wall 311 of the second battery module 300, thereby increasing the contact area between the blocking member 140 and the side wall 311 and enhancing the retaining force of the blocking member 140.

[0045] In some embodiments, the side surface of the blocking member 140 for contacting the side wall 311 is an inclined surface. The side wall 311 of the second battery module 300 is an inclined surface, and the blocking member 140 can contact the side wall 311 of the second battery module 300 .

[0046] In some embodiments, the side surface of the blocking member 140 for contacting the side wall 311 is a curved surface. The side wall 311 of the second battery module 300 is a curved surface, and the blocking member 140 can be contacted with the side wall 311 of the second battery module 300 .

[0047] In some embodiments, as shown in Figures 2 to 5, the blocking member 140 includes a first branch 141, which extends obliquely from the connection position between the main body 110 and the first clip 131 in a direction away from the first clip 120 and the second clip 132, so that the first branch 141 can abut against a partial area of ​​the side wall 311 of the second battery module 300.

[0048] In some embodiments, as shown in Figures 2 to 5, the blocking member 140 includes a second branch 142, which extends obliquely from the connection position between the main body 110 and the second clip 132 in a direction away from the second clip 130 and the first clip 131, so that the second branch 142 can abut against a partial area of ​​the side wall 311 of the second battery module 300.

[0049] In some embodiments, as shown in FIG. 2 to FIG. 5 , the blocking member 140 is in the shape of an elongated strip, that is, the first branch 141 and the second branch 142 are both in the shape of an elongated strip.

[0050] In some embodiments, the blocking member 140 may have any shape, as long as the outer sidewall 311 of the blocking member 140 can abut against the sidewall 311 of the second battery module 300. For example, the blocking member 140 may be rectangular, arc-shaped, or have any irregular structure.

[0051] In some embodiments, the first clip 120 and the second clip 130 are structurally symmetrical about a plane of symmetry, wherein the plane of symmetry is perpendicular to the first direction and passes through the midpoint of the body 110 along the first direction. The first clip 120 and the second clip 130 are structurally symmetrical along the plane of symmetry, that is, the first clip 120 includes a third clip and a fourth clip arranged along the second direction. The third clip extends from the outer wall 311 of the body 110 along the first direction away from the second clip 130, and its end facing away from the body 110 extends along the second direction away from the fourth clip. The fourth clip extends from the outer wall 311 of the body 110 along the first direction away from the second clip 130, and its end facing away from the body 110 extends along the second direction away from the third clip.

[0052] The present application also provides a photovoltaic device, as shown in Figures 3 to 5, comprising a mounting platform 400, a first battery module 200, a second battery module 300, and the aforementioned pressing block 100, wherein the first clamping member 120 of the pressing block 100 is clamped to the first battery module 200, the second clamping member 130 is clamped to the second battery module 300, and the pressing block 100 is connected to the mounting platform 400 via a fastener 500. By providing the pressing block 100 to connect the first battery module 200 and the second battery module 300, when the first battery module 200 and the second battery module 300 are assembled, the first clamping member 120 of the pressing block 100 is first clamped to the first battery module 200, the pressing block 100 is then connected to the mounting platform 400 via the fastener 500, and finally the second battery module 300 is pushed in a first direction toward the pressing block 100, so that the second clamping member 130 undergoes elastic deformation in a second direction and is clamped to the second battery module 300. Compared with the existing method of tilting the second battery module 300 to snap into contact with the pressing block 100, the photovoltaic device provided in the present application only needs to push the second battery module 300 along the first direction to achieve snap connection during splicing, which reduces the installation difficulty, increases the installation speed, and improves the installation efficiency.

[0053] It should be noted that the first battery module 200 and the second battery module 300 have the same structure, and are respectively referred to as the first battery module 200 and the second battery module 300 herein only for the convenience of distinguishing their relative positions to the pressing block 100 .

[0054] In some embodiments, as shown in Figures 3 to 5, the first battery module 200 includes a first laminate 220 and a first frame assembly 210. The first frame assembly 210 is arranged around the circumference of the first laminate 220. A first card slot 211 is provided on the side wall 311 of the first frame assembly 210. The first card 120 can extend into the first card slot 211 and be engaged with the first card slot 211.

[0055] In some embodiments, as shown in Figures 3 to 5 and Figure 9, the second battery module 300 includes a second laminate 320 and a second frame assembly 310. The second frame assembly 310 is arranged around the circumference of the second laminate 320. A second card slot 312 is provided on the side wall 311 of the second frame assembly 310. The second card 130 can extend into the second card slot 312 and be engaged with the second card slot 312.

[0056] In some embodiments, as shown in Figures 3 to 5, a second snap-in slot 312 is provided on the second frame assembly 310, and the first snap-in clips 131 and the second snap-in clips 132 arranged along the second direction of the second snap-in member 130 are both snapped into the second snap-in slot 312. When the compression block 100 and the second battery module 300 need to be connected, the second battery module 300 is pushed along the first direction toward the compression block 100, and the first snap-in clip 131 and the second snap-in clip 132 of the second snap-in member 130 are both elastically deformed along the second direction, thereby extending the first snap-in clip 131 and the second snap-in clip 132 into the second snap-in slot 312, thereby achieving the snap-in connection between the compression block 100 and the second frame assembly 310.

[0057] In some embodiments, as shown in Figures 3 to 5 , the blocking member 140 on the body 110 abuts against the sidewall 311 of the second frame assembly 310. That is, the first leg 141 and the second leg 142 of the blocking member 140 abut against different areas on the sidewall 311 to limit the movement of the second battery module 300 along the second direction.

[0058] It should be noted that, in the art, the bottom wall of the first frame assembly 210 / second frame assembly 310 is referred to as the C-side, the top wall of the first frame assembly 210 / second frame assembly 310 is referred to as the A-side, and the side wall 311 of the first frame assembly 210 / second frame assembly 310 is referred to as the B-side. A first card slot 211 is provided on the side wall 311 of the first frame assembly 210, i.e., the first card slot 211 is provided on the B-side of the first frame assembly 210, and a second card slot 312 is provided on the side wall 311 of the second frame assembly 310, i.e., the second card slot 312 is provided on the B-side of the second frame assembly 310.

[0059] In some embodiments, as shown in Figures 3 to 5, the end of the first frame assembly 210 of the first battery module 200 that is away from the installation platform 400 along the second direction is flush with the end of the first laminate 220 of the first battery module 200 that is away from the installation platform 400 along the second direction; that is, the A surface of the first frame assembly 210 is flush with the upper surface of the first laminate 220. When rainwater falls on the upper surface of the first laminate 220, the rainwater can drive the dust on the first laminate 220 to flow through the area on the first frame assembly 210 that is flush with the surface of the first laminate 220, and then flow out of the first battery module 200 through the area, thereby reducing the dust accumulation on the first laminate 220 and improving the anti-dust accumulation performance of the first battery module 200.

[0060] In some embodiments, as shown in Figures 3 to 5, one end of the second frame assembly 310 of the second battery module 300 that faces away from the mounting platform 400 along the second direction is flush with one end of the second laminate 320 of the second battery module 300 that faces away from the mounting platform 400 along the second direction. That is, the A surface of the second frame assembly 310 is flush with the upper surface of the second laminate 320. When rain falls on the upper surface of the second laminate 320, the rain can drive dust on the second laminate 320 to flow through the area of ​​the second frame assembly 310 that is flush with the surface of the second laminate 320, and then flow out of the second battery module 300 through this area, thereby reducing dust accumulation on the second laminate 320 and improving the dust accumulation prevention performance of the second battery module 300.

[0061] In some embodiments, as shown in Figure 6, the present application also provides a structural schematic diagram of a photovoltaic device, wherein the difference between Figure 5 and Figure 6 is the different structure of the card slot. Although the card slot structures in Figure 5 and Figure 6 are different, they can both be connected with the first card member 120 and the second card member 130.

[0062] In some embodiments, as shown in FIG7 , the present application further provides a schematic structural diagram of a photovoltaic device, wherein the difference between FIG5 and FIG7 is the different structures of the first latch 131 and the second latch 132 of the second latch 130. It is understood that although the structures of the second latch 130 in FIG5 and FIG7 are different, they both achieve a snap connection with the second latch slot 312.

[0063] In some embodiments, as shown in Figure 8, the present application also provides a structural schematic diagram of a photovoltaic device, wherein the difference between Figure 5 and Figure 8 is the different structure of the card slot. Although the card slot structures in Figure 5 and Figure 8 are different, they can both be connected with the first card member 120 and the second card member 130.
