Description

Technical Field

[0001] This application relates to the field of photovoltaic louver technology, and in particular to an electrical connection component, a photovoltaic louver, and a power generation system. Background Technology

[0002] Photovoltaic louvers integrate thin-film solar cells into the louver blades, utilizing the photovoltaic effect to convert solar energy into direct current (DC). The DC power is then collected at the busbar and converted into alternating current (AC) by an inverter, enabling self-consumption, energy storage, or grid connection, thus providing both shading and power generation.

[0003] In related technologies, photovoltaic louvers include multiple blades and thin-film solar cells mounted on each blade. The thin-film solar cells need to be electrically connected to a busbar, and the electrical connection method is as follows: the thin-film solar cells are connected to the busbar via wires and branch terminals. Specifically, the busbar is connected to the branch terminals, one end of the wire is connected to the thin-film solar cell, and the other end is connected to the branch terminal. The electrical connection between the busbar and the wire is achieved through the conductor structure within the branch terminal.

[0004] However, because the blades of photovoltaic louvers need to be raised, lowered, and have their angles changed during use, the aforementioned wires are inevitably prone to being pulled and swaying during these movements, which can easily lead to loosening or damage at the connections. Furthermore, the wires lengthen the conductive path between the thin-film solar cells and the busbar, resulting in reduced conductivity and hindering the compact design and aesthetic improvement of the overall photovoltaic louver structure. Summary of the Invention

[0005] In view of the problems existing in the background art, the purpose of this application is to provide an electrical connection component, a photovoltaic louver and a power generation system that overcomes or at least partially solves the above problems.

[0006] According to a first aspect of this application, an electrical connection assembly is provided, including a housing and at least one conductive component. The housing has a mounting cavity and a first through hole, the first through hole extending along a first direction and communicating with the mounting cavity.

A mounting cavity and a first through hole are both located in the mounting portion, and the first and second pressure plates are disposed opposite each other on the mounting portion.

[0010] In one or more of the above optional embodiments, the electrical connection assembly includes two conductive components. A first pressure plate has two first grooves spaced apart along a third direction. A second pressure plate has second grooves corresponding to the first grooves. The first and second grooves are aligned along a first direction to form a limiting region for accommodating clamping portions. The clamping portion of one conductive component is located in one limiting region, and the clamping portion of the other conductive component is located in the other limiting region. The second pressure plate also includes a snap-fit ​​plate connected between the groove walls of two adjacent second grooves. A second through hole is formed in the snap-fit ​​plate. The snap-fit ​​plate is closer to the first pressure plate than the bottom of the second groove. In the first direction, the snap-fit ​​plate has a predetermined vertical distance from the bottom of the second groove. A hook head is used to hold the snap-fit ​​plate. The first direction, the second direction, and the third direction are all perpendicular to each other.

[0011] In one or more of the above optional embodiments, the portion of the fastener located between the first pressure plate and the second pressure plate is also used to pass through the mounting hole of the photovoltaic blade.

[0012] In one or more of the above optional embodiments, the first spring sheet protrudes toward the second spring sheet to form a first arc-shaped portion, and the second spring sheet protrudes toward the first spring sheet to form a second arc-shaped portion.

[0014] In one or more of the above optional embodiments, the mounting part is provided with a second through hole extending along the second direction and penetrating the mounting part. The second through hole communicates with the mounting cavity. The conductive component is inserted into the mounting cavity through the second through hole and the clamping part passes through the second through hole.

[0015] In one or more of the above optional embodiments, a first limiting groove and a second limiting groove are provided on opposite sides of the mounting part, and the first limiting groove and the second limiting groove are used to engage with the edge of the photovoltaic blade.

[0016] In one or more of the above optional embodiments, a buckle part is provided in the second through hole, and a slot is provided in the threading part, with the slot engaging with the buckle part.

[0017] According to a second aspect of this application, a photovoltaic louver is provided, comprising a plurality of photovoltaic blades arranged along a first direction, a plurality of the aforementioned electrical connection components, and two busbars. Each photovoltaic blade has two conductive electrodes, each having a first polarity and a second polarity, with the first and second polarities having opposite polarities. The plurality of electrical connection components are arranged in a row along the first direction on the plurality of photovoltaic blades. Each electrical connection component includes two conductive components mounted side-by-side in a mounting cavity, with two clamping portions of the same electrical connection component clamping two conductive electrodes of a photovoltaic blade. In the first direction, a busbar sequentially passes through through-holes in a plurality of conductive components for clamping conductive electrodes of the first polarity. In the first direction, another busbar sequentially passes through through-holes in a plurality of conductive components for clamping conductive electrodes of the second polarity.

[0018] In one or more of the above optional embodiments, the photovoltaic blade is provided with a connecting plate, and the conductive electrode includes a first part and a second part disposed opposite to each other on both sides of the connecting plate, and the clamping part is clamped in the first part and the second part respectively.

[0019] According to a third aspect of this application, a power generation system is provided, comprising the aforementioned photovoltaic louvers, a microinverter, and / or an energy storage power source.

The energy storage power source is used to store the DC power converted from solar energy by the photovoltaic louvers.

[0020] The beneficial effects of this application embodiment are as follows: When the electrical connection assembly provided in this application embodiment is applied to a photovoltaic louver, the clamping part clamps and fixes the conductive electrode of the photovoltaic blade in the clamping area. The clamping part is electrically connected to the conductive electrode through abutment contact. The busbar of the photovoltaic louver passes through the first through hole and is electrically connected to the conductive electrode through the wire-passing part and the clamping part. Compared with the related technology, which uses a wire to connect to a branch terminal and then the branch terminal to connect to the busbar, the electrical connection assembly provided in this application embodiment eliminates the connecting wire between the photovoltaic blade and the busbar. This avoids the problem of loosening or damage at the connection point caused by the wire being pulled and swayed when the photovoltaic blade rises, falls, and changes angle. It also shortens the conductive path between the photovoltaic blade and the busbar, improves the conductivity between the photovoltaic blade and the busbar, and enhances the compactness and aesthetics of the overall structure of the photovoltaic louver.

[0033] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0034] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0035] Please see Figure 1 and Figure 2 The electrical connection assembly 2 includes a housing 21 and at least one conductive component 22. The housing 21 has a mounting cavity A and a first through hole 2138, which extends along a first direction X and communicates with the mounting cavity A. Each conductive component 22 includes a wire-passing portion 222 and a clamping portion 221 connected to each other. The wire-passing portion 222 is mounted in the mounting cavity A and has a wire-passing hole 2221 that communicates with the first through hole 2138 within the mounting cavity A. The clamping portion 221 connects to the wire-passing portion 222 and extends beyond the mounting cavity A. The clamping portion 221 forms a clamping area a, which is arranged side-by-side with the wire-passing hole 2221 along a second direction Y. The clamping area a of the clamping portion 221 is used to clamp the conductive electrode 132 of the photovoltaic blade 1. The first through hole 2138 and the wire-passing hole 2221 are used for the busbar 3 to pass through. The first direction X and the second direction Y can be perpendicular to each other.

[0036] The electrical connection component 2 provided in this application embodiment, when applied to a photovoltaic louver 1000, uses a clamping part 221 to clamp and fix the conductive electrode 132 of the photovoltaic blade 1 to the clamping area a. The clamping part 221 is electrically connected to the conductive electrode 132 through abutment contact. The busbar 3 of the photovoltaic louver 1000 passes through the first through hole 2138 and the wire hole 2221. The busbar 3 is electrically connected to the conductive electrode 132 through the wire hole 222 and the clamping part 221. Compared with the related technology, which uses a wire to connect to a branch terminal and then the branch terminal to connect to the busbar 3, the electrical connection component 2 provided in this application embodiment eliminates the connecting wire between the photovoltaic blade 1 and the busbar 3. This avoids the problem of loosening or damage at the connection point caused by the wire being pulled and swayed when the photovoltaic blade 1 rises, falls, and changes in angle. It also shortens the conductive path between the photovoltaic blade 1 and the busbar 3, improves the conductivity between the photovoltaic blade 1 and the busbar 3, and enhances the compactness and aesthetics of the overall structure of the photovoltaic louver 1000.

[0037] It is worth noting that in order to generate electricity from the photovoltaic louver 1000, each photovoltaic blade 1 needs to be connected to the bus 3. If each photovoltaic blade 1 is connected to a bus 3, and then multiple bus 3s are connected to the inverter, the wiring method is too complicated and affects the overall appearance, and is also not conducive to wiring deployment.

[0038] Understandably, a photovoltaic louver 1000 typically includes multiple photovoltaic blades 1 arranged in rows. In this embodiment, the clamping area a and the wiring hole 2221 are arranged side by side in the second direction Y, and the busbar 3 passes through the wiring hole 2221 in the first direction X. Thus, when the photovoltaic blades are arranged in rows along the first direction X, a conductive connection component 2 is provided on each photovoltaic blade 1. The photovoltaic louver 1000 connects each photovoltaic blade 1 and the conductive connection component 2 in the second direction Y. A busbar 3 passes through multiple conductive connection components 2 sequentially through the wiring hole 2221 in the first direction X, thus enabling a single busbar 3 to achieve conductive connection with multiple photovoltaic blades 1. Therefore, the structure of the conductive connection component 2 in this embodiment facilitates the wiring deployment of multiple photovoltaic blades 1, simplifies the wiring method, and saves wiring profiles.

[0039] In some embodiments, the conductive component 22 includes, but is not limited to, being made of copper.

[0040] In some embodiments, the clamping portion 221 includes a first spring piece 2211 and a second spring piece 2212 disposed opposite to each other, the first spring piece 2211 and the second spring piece 2212 being disposed opposite to each other in a first direction X to form a clamping region a.

[0041] In some embodiments, the first spring 2211 undergoes elastic deformation along the direction of the second spring 2212 toward the first spring 2211 to apply an elastic force to the conductive electrode 132 along the direction of the first spring 2211 toward the second spring 2212. The second spring 2212 undergoes elastic deformation along the direction of the first spring 2211 toward the second spring 2212 to apply an elastic force to the conductive electrode 132 along the direction of the second spring 2212 toward the first spring 2211. After the first spring 2211 and the second spring 2212 undergo elastic deformation, they can better fit against both sides of the conductive electrode 132, which is beneficial to improving the reliability of the electrical connection between the clamping part 221 and the conductive electrode 132.

[0042] In some embodiments, the clamping part 221 includes a connecting piece 2213, one end of the first spring piece 2211 and one end of the second spring piece 2212 are connected to the connecting piece 2213. Along a direction parallel to the first direction X, the end of the first spring piece 2211 away from the connecting piece 2213 is used to abut against one side of the conductive electrode 132, and the end of the second spring piece 2212 away from the connecting piece 2213 abuts against the other side of the conductive electrode 132. The connecting piece 2213 is connected to the threading part 222.

[0043] In some embodiments, the connecting piece 2213 is welded to the threading portion 222.

[0044] In some embodiments, the first spring piece 2211 protrudes towards the second spring piece 2212 to form a first arcuate portion 2211a, and the second spring piece 2212 protrudes towards the first spring piece 2211 to form a second arcuate portion 2212a. The first arcuate portion 2211a and the second arcuate portion 2212a are used to clamp the conductive electrode 132 of the photovoltaic blade 1. By providing the first arcuate portion 2211a and the second arcuate portion 2212a to clamp the conductive electrode 132, the clamping portion 221 can better fit the surface of the conductive electrode 132, which is beneficial to improving the stability of clamping and the reliability of electrical connection.

[0045] In some embodiments, the housing 21 includes a mounting portion 213, a first pressure plate 211 and a second pressure plate 212. The mounting cavity A and the first through hole 2138 are both provided on the mounting portion 213. The first pressure plate 211 and the second pressure plate 212 are disposed opposite to each other on the mounting portion 213. Along the first direction X, the clamping portion 221 is disposed between the first pressure plate 211 and the second pressure plate 212.

[0046] In some embodiments, the first pressure plate 211 and the second pressure plate 212 are respectively used to abut against the first spring piece 2211 and the second spring piece 2212. The first pressure plate 211 and the second pressure plate 212 limit the first spring piece 2211 and the second spring piece 2212, so that the first spring piece 2211 and the second spring piece 2212 maintain a stable abutment state with the conductive electrode 132, which is beneficial to further improve the reliability of the electrical connection between the clamping part 221 and the conductive electrode 132.

[0047] In some embodiments, the electrical connection assembly 2 further includes a fastener 23 for detachably connecting the first pressure plate 211 and the second pressure plate 212. The fastener 23 is detachably connected between the first pressure plate 211 and the second pressure plate 212, and the fastener 23 connects the first pressure plate 211 and the second pressure plate 212 together, which helps to maintain the continuous limiting effect of the first pressure plate 211 and the second pressure plate 212 on the first spring piece 2211 and the second spring piece 2212.

[0048] In some embodiments, the fastener 23 is used to apply a force to the first pressure plate 211 in the direction from the first pressure plate 211 to the second pressure plate 212, and to apply a force to the second pressure plate 212 in the direction from the second pressure plate 212 to the first pressure plate 211. Under the action of the fastener 23, the first pressure plate 211 and the second pressure plate 212 can respectively apply opposing thrusts to the first spring piece 2211 and the second spring piece 2212, so that the first spring piece 2211 and the second spring piece 2212 respectively better abut against the conductive electrode 132.

[0049] In some embodiments, one end of the fastener 23 is provided with an abutment portion 231, and the other end of the fastener 23 is provided with a hook head 233. The first pressure plate 211 has a first through hole 2111, and the second pressure plate 212 has a second through hole (not shown) that is directly opposite to the first through hole 2111. The fastener 23 passes through the first through hole 2111 and the second through hole. The abutment portion 231 abuts against the side of the first pressure plate 211 facing away from the second pressure plate 212, and the hook head 233 is engaged with the side of the second pressure plate 212 facing away from the first pressure plate 211.

[0050] In some embodiments, there are two hook heads 233, which are arranged opposite to each other. The diameter of the first through hole 2111 is larger than the diameter of the second through hole. When the fastener 23 passes through the first through hole 2111 and into the second through hole, the inner wall of the second through hole is used to make the relative distance between the two hook heads 233 smaller. After the hook head 233 passes through the second through hole, the relative distance between the two hook heads 233 increases to hold the second pressure plate 212.

[0051] In some embodiments, the fastener 23 includes a connecting portion 232, which is connected between the hook head 233 and the abutment portion 231, and the connecting portion 232 passes through the first through hole 2111 and the second through hole.

[0052] In some embodiments, under the action of the fastener 23, the first pressure plate 211 undergoes elastic deformation toward the second pressure plate 212, thereby applying pressure to the first spring sheet 2211 in the direction from the first spring sheet 2211 to the second spring sheet 2212, and / or, under the action of the fastener 23, the second pressure plate 212 undergoes elastic deformation toward the first pressure plate 211, thereby applying pressure to the second spring sheet 2212 in the direction from the second spring sheet 2212 to the first spring sheet 2211.

[0053] In some embodiments, the portion of the fastener 23 located between the first pressure plate 211 and the second pressure plate 212 is also used to pass through the mounting hole 133 of the photovoltaic blade 1. The fastener 23 passes through the mounting hole 133, and the inner wall of the mounting hole 133 can limit the fastener 23, thereby restricting the movement of the electrical connection assembly 2 relative to the photovoltaic blade 1. This helps to reduce the problem of poor contact between the clamping part 221 and the conductive electrode 132 due to relative sliding under external force.

[0054] In some embodiments, the connecting portion 232 passes through the mounting hole 133.

[0055] In other embodiments, fastener 23 includes a bolt (not shown) and a nut (not shown), the bolt passing through the first pressure plate 211 and the second pressure plate 212 and being screwed to the nut.

[0056] Please see Figure 2 - Figure 5 In some embodiments, the first pressure plate 211 has a first groove 2112, and the second pressure plate 212 has a second groove 2122. The first groove 2112 and the second groove 2122 are arranged opposite each other along the first direction X to form a limiting region b for accommodating the clamping part 221. The clamping part 221 is disposed in the limiting region b, and the first groove 2112 and the second groove 2122 together limit the clamping part 221.

[0057] In some embodiments, the first spring piece 2211 is disposed in the first groove 2112, and the second spring piece 2212 is disposed in the second groove 2122.

[0058] In some embodiments, the electrical connection assembly 2 includes two conductive components 22. The two through-wire portions 222 of the two conductive components 22 are respectively used for two busbars 3 to pass through, and the two clamping portions 221 of the two conductive components 22 are respectively used to clamp two conductive electrodes 132 of opposite polarity of the photovoltaic blade 1.

[0059] In some embodiments, the first pressure plate 211 has two first grooves 2112 spaced apart along the third direction Z, and the second pressure plate 212 has second grooves 2122 that correspond one-to-one with the first grooves 2112. The clamping part 221 of one conductive component 22 is provided in a limiting region b, and the clamping part 221 of another conductive component 22 is provided in another limiting region b.

[0060] In some embodiments, the first direction X, the second direction Y, and the third direction Z are mutually perpendicular to each other.

[0061] In some embodiments, the second pressure plate 212 further includes a snap-fit ​​plate 2123 connected between the groove walls of two adjacent second grooves 2122, a second through hole being formed in the snap-fit ​​plate 2123, the snap-fit ​​plate 2123 being closer to the first pressure plate 211 than the bottom of the groove of the second groove 2122, and in the first direction X, the snap-fit ​​plate 2123 having a preset vertical distance from the bottom of the groove of the second groove 2122; the snap hook head 233 is used to hold the snap-fit ​​plate 2123.

[0062] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, the threading part 222 is provided with a connecting hole 2222, which is used to connect the threading hole 2221 and the first through hole 2138; the busbar 3 passing through the threading hole 2221 is fixed to the hole wall 2221a of the threading hole 2221 by a second fastener 24 passing through the connecting hole 2222.

[0063] In some embodiments, the connection hole 2222 extends along the second direction Y.

[0064] In some embodiments, the connecting hole 2222 does not penetrate the wire passage 222. The connecting hole 2222 is located on one side of the wire passage 2221. One end of the connecting hole 2222 has an opening formed on the surface of the wire passage 222. The other end of the connecting hole 2222 communicates with the wire passage 2221. The second fastener 24 passes through the connecting hole 2222 and extends into the wire passage 2221. The busbar 3 has an exposed section (not shown) with exposed conductor. The exposed section is located in the wire passage 2221. The second fastener 24 abuts against the exposed section in the wire passage 2221. The hole wall 2221a of the wire passage 2221 and the second fastener 24 together clamp and fix the exposed section.

[0065] Reference Figure 2In some embodiments, the threading portion 222 includes a first side (not shown), a second side (not shown), a third side (not shown), and a fourth side (not shown). The first and second sides are both disposed opposite each other along a first direction X, and the third and fourth sides are disposed opposite each other along a second direction Y. Both the first and second sides are connected to the third side, and both the first and second sides are connected to the fourth side. The threading hole 2221 penetrates through the first and second sides, and the connecting hole 2222 extends from the third side along the second direction Y to the side of the fourth side facing the third side. Therefore, the connecting hole 2222 does not penetrate the threading portion 222. Thus, when the second fastener 24 secures the busbar 3, the busbar 3 will not bend beyond the fourth side, which helps protect the busbar 3.

[0066] In some embodiments, the connecting hole 2222 is a threaded hole, the second fastener 24 is a bolt, and the second fastener 24 is screwed into the connecting hole 2222 along the second direction Y.

[0067] It is understood that in some other embodiments, the exposed section can also be connected to the threaded part 222 by welding, or in some other embodiments, the threaded part 222 or the second fastener 24 can also be provided with an annular blade-shaped structure, which can penetrate the outer sheath of the busbar 3 and contact the conductor inside the busbar 3 to achieve electrical connection.

[0068] Please see Figure 2 , Figure 3 and Figure 6 In some embodiments, the mounting portion 213 is provided with a second through hole 2133 extending along the second direction Y and penetrating the mounting portion 213. The second through hole 2133 communicates with the mounting cavity A. The conductive component 22 is inserted into the mounting cavity A through the second through hole 2133 and the clamping portion 221 passes through the second through hole 2133.

[0069] Please see Figure 5 , Figure 7 and Figure 8 In some embodiments, the mounting portion 213 has a first limiting groove 2136 and a second limiting groove 2137 on opposite sides. The first limiting groove 2136 and the second limiting groove 2137 are used to engage with the edge of the photovoltaic blade 1. The first limiting groove 2136 and the second limiting groove 2137 are respectively engaged with the edge of the photovoltaic blade 1, making the mounting portion 213 and the photovoltaic blade 1 relatively stable. This helps to reduce the relative shaking between the mounting portion 213 and the photovoltaic blade 1, and thus helps to improve the stability of the connection between the conductive component 22 and the conductive electrode 132.

[0070] It is understood that the mounting part 213 is not limited to being detachably connected to the photovoltaic blade 1 by the above-described snap-fit ​​method.
