Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, and in particular to a photovoltaic module and its assembly method. Background Technology

[0002] Photovoltaic modules, as the core component of photovoltaic systems, are used to convert solar energy into electrical energy, which is then stored in batteries or used to power loads. They have significant advantages such as simple energy conversion process, no pollution emissions, and no noise, and have good application prospects. They can be used to provide basic living electricity for remote areas without electricity, such as plateaus, islands, pastoral areas and border outposts, as well as to provide the necessary power for public transportation facilities such as highways, railways and airports.

[0003] There are two main installation methods for photovoltaic modules: long-side fixing and short-side fixing. For example, there are four-point, six-point, or four-point installation methods on the long side. Although these installation methods can fix the photovoltaic modules, the load that the photovoltaic modules can withstand is relatively low, and they cannot adapt to extreme weather such as strong winds or heavy snow, and their adaptability to the external environment is poor. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a photovoltaic module and its assembly method, which solves the technical problem of poor adaptability of existing photovoltaic modules to the external environment.

[0005] To achieve the above objectives, the present invention provides a photovoltaic module, including a module body, a module frame surrounding the outer edge of the module body, and a support member connected to the module frame; the end of the support member is fixedly provided with a connector, the connector passing through the module frame, and the connector is fitted with an outer locking member, an outer clamping plate, an inner clamping plate, and an inner locking member; the outer clamping plate is disposed between the outer locking member and the outer side of the module frame, and the inner clamping plate is disposed between the inner locking member and the inner side of the module frame.

[0006] Preferably, the component frame is provided with a mounting hole, and the connector includes a screw that passes through the mounting hole. The screw includes an external threaded section located on the outside of the component frame and an internal threaded section located on the inside of the component frame. The external locking member is an external nut that is threadedly engaged with the external threaded section, and the internal locking member is an internal nut that is threadedly engaged with the internal threaded section.

[0007] Preferably, the component frame includes an inner side plate and a bottom side plate, the inner side plate and the bottom side plate intersecting perpendicularly to form an L-shaped clamping groove; the inner clamping plate is an L-shaped clamping plate that mates with the L-shaped clamping groove.

[0008] Preferably, the L-shaped clamping plate includes an integral vertical clamping plate and a horizontal clamping plate arranged at an angle. The vertical clamping plate abuts against the inner side plate, and the horizontal clamping plate abuts against the bottom side plate. The thickness of the vertical clamping plate is greater than the thickness of the horizontal clamping plate. The vertical clamping plate and the horizontal clamping plate are smoothly connected by a transition rounded corner, and the transition rounded corner matches the arc corner of the L-shaped clamping groove.

[0009] Preferably, the component frame also includes an outer side plate that is perpendicularly connected to the bottom side plate, and a limiting protrusion is formed at the connection between the outer side plate and the bottom side plate; a limiting groove is formed at the bottom of the outer side plate, and the limiting groove and the limiting protrusion are in concave-convex fit.

[0010] Preferably, an inner elastic washer is provided between the inner clamping plate and the inner locking member, and an outer elastic washer is provided between the outer clamping plate and the outer locking member; both the inner elastic washer and the outer elastic washer are fitted onto the connector.

[0011] Preferably, the support includes a rigid rope with plugs at both ends; the connector also includes a plug sleeve fixedly connected to the screw, and the plug and the plug sleeve are plugged into each other.

[0012] Preferably, a limiting boss is formed at the connection between the screw and the plug sleeve, and the limiting boss is used to prevent the inner locking member from disengaging from the screw.

[0013] Preferably, the component frame has a clamping groove for clamping the outer edge of the component body; an overflow groove is formed inside the clamping groove.

[0014] The present invention also provides a method for assembling a photovoltaic module, applied to the above-mentioned photovoltaic module, the steps of which include:

[0015] Install the inner locking component and the inner clamping plate onto the connector of the support component in sequence;

[0016] Insert the connector into the mounting hole provided on the component frame;

[0017] Then install the outer clamping plate and the outer locking component onto the connector in sequence;

[0018] Lock the inner and outer locking parts.

[0019] Compared with the prior art, the present invention optimizes the connection relationship between the component body and the component frame. The end of the support member is fixedly provided with a connector, which passes through the component frame. The connector is fitted with an outer locking member, an outer clamping plate, an inner clamping plate, and an inner locking member. During assembly, the outer locking member and the inner locking member are simultaneously locked and fixed to the connector. The outer clamping plate is located between the outer locking member and the outer side of the component frame, and the inner clamping plate is located between the inner locking member and the inner side of the component frame.

[0020] When a large load is applied to the support component of the module body, the support component deforms. The inner clamp provides upward support to one end of the connector, while the outer clamp provides downward support to the other end. In this way, the support forces borne by the two ends of the connector cancel each other out, reducing the impact of the load on the connector and thus reducing the squeezing force exerted by the connector on the module frame. This reduces the risk of the module frame being crushed by the connector, enabling the module frame to withstand the strong loads applied by the module body under extreme conditions such as strong winds or heavy snow. The load range that the module frame can withstand is increased, effectively improving the photovoltaic system's adaptability to the external environment. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] This invention discloses a photovoltaic module, as shown in the attached figure. Figure 1 As shown, the module includes a module body 1, a module frame 2, and a support member 3. The module body 1 includes a glass layer, solar cells, and a backsheet. Both the glass layer and the backsheet serve to protect and encapsulate the components. The glass layer and the solar cells are bonded together with an adhesive. The module body 1 utilizes the photovoltaic effect to convert solar energy into electrical energy, which can then be used to power loads or stored in batteries. The module frame 2 surrounds the outer edge of the module body 1. The module frame 2 can be an aluminum alloy frame, a steel frame, or a composite material frame. It protects the module body 1 from damage by the external environment and provides stable support, ensuring that the module body 1 can operate normally under various environmental conditions.

[0039] As attached Figure 1 As shown, each component frame 2 is provided with at least one support member 3. In a preferred embodiment, the component frame 2 is a rectangular frame, and each end of the component frame 2 is provided with a support member 3, and each support member 3 extends along the width direction of the component frame 2.

[0040] As attached Figures 2 to 5 As shown, a connector 31 is fixedly provided at the end of the support member 3, and the connector 31 passes through the component frame 2. Specifically, each end of each support member 3 is provided with a connector 31 for fixing the support member 3 to the component frame 2. The connector 31 is fitted with an outer locking member 4, an outer clamping plate 5, an inner clamping plate 6, and an inner locking member 7, wherein the outer locking member 4 and the outer clamping plate 5 are located on the outer side of the component frame 2, and the inner clamping plate 6 and the inner locking member 7 are located on the inner side of the component frame 2.

[0041] During assembly, the outer locking member 4 and the inner locking member 7 are simultaneously locked and fixed to the connector 31. The outer clamping plate 5 is disposed between the outer locking member 4 and the outer side of the component frame 2, as shown in the attached figure. Figure 2 and 3 As shown, the inner clamping plate 6 is disposed between the inner locking member 7 and the inner side of the component frame 2.

[0042] When a large load is applied to the support member 3 by the module body 1, the support member 3 deforms. The inner clamping plate 6 provides an upward supporting force to one end of the connector 31, and the outer clamping plate 5 provides a downward supporting force to the other end of the connector 31. In this way, the supporting forces borne by the two ends of the connector 31 cancel each other out, reducing the impact of the load on the connector 31, thereby reducing the squeezing force exerted by the connector 31 on the module frame 2, reducing the risk of the module frame 2 being crushed by the connector 31, and enabling the module frame 2 to withstand the strong load applied by the module body 1 under extreme conditions such as strong winds or heavy snow. The load range that the module frame 2 can withstand is increased, effectively improving the photovoltaic system's adaptability to the external environment.

[0043] As attached Figure 4 As shown, the component frame 2 has a through mounting hole 21. The connector 31 includes a screw 311 passing through the mounting hole 21. The screw 311 includes an external thread section located on the outside of the component frame 2 and an internal thread section located on the inside of the component frame 2. The external locking member 4 is an external nut that is threadedly engaged with the external thread section, and the internal locking member 7 is an internal nut that is threadedly engaged with the internal thread section. The external nut and the internal nut apply a preload to the connector 31, so that the connector 31 is detachably fixed to the component frame 2 by the external nut and the internal nut, ensuring that both ends of the support member 3 are reliably fixed to the component frame 2 and facilitating the disassembly and assembly of the support member 3. The number of external nuts and internal nuts is not limited to one. The number of external nuts and internal nuts can be appropriately increased according to the specifications of the component body 1 and the application, increasing the preload and preventing the connector 31 from loosening and causing the support member 3 to be unstable, thus ensuring high safety.

[0044] As attached Figure 3 As shown, the component frame 2 includes an inner side plate 22 and a bottom side plate 23. The inner side plate 22 and the bottom side plate 23 intersect perpendicularly to form an L-shaped clamping groove. The inner clamping plate 6 is an L-shaped clamping plate. The L-shaped clamping plate and the L-shaped clamping groove cooperate to improve the mechanical connection strength between the support member 3 and the component frame 2, and also provide support for the connector 31.

[0045] As a preferred embodiment, as shown in the appendix Figure 3As shown, the L-shaped clamp includes an integrally formed vertical clamp 61 and a horizontal clamp 62 arranged at an angle. The vertical clamp 61 abuts against the inner side plate 22, and the horizontal clamp 62 abuts against the bottom side plate 23. The vertical clamp 61 and the horizontal clamp 62 are at a 90° angle. The thickness of the vertical clamp 61 is greater than the thickness of the horizontal clamp 62, allowing the L-shaped clamp to provide support for the connector 31 under the compression of the inner locking member 7. The vertical clamp 61 and the horizontal clamp 62 are smoothly connected by a transition rounded corner, which matches the arc corner of the L-shaped clamping groove, thus restricting the position of the L-shaped clamp and ensuring that the L-shaped clamp is firmly fixed. Of course, the inner clamp 6 can also be a plate-like structure, without affecting the purpose of the present invention.

[0046] Component frame 2 also includes an outer side plate 24 that is perpendicularly connected to the bottom side plate 23, as shown in the attached figure. Figure 3 As shown, a limiting protrusion 25 is formed at the connection between the outer side plate 24 and the bottom side plate 23; the outer side clamping plate 5 is a plate-shaped structure, and a limiting groove is formed at the bottom of the outer side clamping plate 5. The limiting groove and the limiting protrusion 25 are in a concave-convex fit. When the outer locking member 4 is locked, the outer side clamping plate 5 pulls the limiting protrusion 25 to provide a downward pulling force to the connector 31 after the support member 3 is deformed by load. The limiting protrusion 25 is specifically a rounded corner structure.

[0047] As attached Figures 2 to 4 As shown, an inner elastic washer 8 is provided between the inner clamping plate 6 and the inner locking member 7, and an outer elastic washer 9 is provided between the outer clamping plate 5 and the outer locking member 4. Both the inner elastic washer 8 and the outer elastic washer 9 are fitted onto the connector 31 to prevent the inner locking member 7 and the outer locking member 4 from loosening during installation, thereby improving the fastening performance between the inner locking member 7 and the connector 31 and between the outer locking member 4 and the connector 31.

[0048] As attached Figure 3 and 4 As shown, the support member 3 includes a rigid rope 32, which can specifically be a steel cable, used to support the main body 1. The rigid rope 32 has a simple structure and strong load-bearing capacity. Both ends of the rigid rope 32 are provided with connectors 321; the connector 31 also includes a connector sleeve 312 fixedly connected to the screw 311. The connector sleeve 312 and the connector 321 are inserted into each other, increasing the contact area between the rigid rope 32 and the connector 31. Furthermore, the connection between the connectors 321 and 321 is crimped, improving the mechanical connection strength between the rigid rope 32 and the connector 31, reducing the risk of breakage of the support member 31, and ensuring a reliable connection between the rigid rope 32 and the connector 31.

[0049] A limiting boss 313 is formed at the connection between the screw 311 and the insertion sleeve 312, as shown in the attached figure. Figure 3As shown, the limiting boss 313 is used to limit the inner locking member 7 from disengaging from the screw 311, avoid the risk of accidental breakage of the support member 3, reduce the risk of the component body 1 falling, and effectively improve safety.

[0050] The component frame 2 has a clamping groove 26, as shown in the attached figure. Figure 2 and 3 As shown, the clamping groove 26 is used to clamp the outer edge of the component body 1, so that the component frame 2 supports the component body 1. An overflow groove 261 is formed in the clamping groove 26 to collect and contain excess glue and prevent glue from overflowing.

[0051] The present invention also provides a method for assembling a photovoltaic module, applicable to the aforementioned photovoltaic module, comprising the following steps: after the rigid rope 32 is pressed and connected to the connector 31, the inner locking member 7 and the inner clamping plate 6 are first sequentially fitted onto the connector 31 of the support member 3; then the connector 31 is inserted into the mounting hole 21 provided in the module frame 2; next, the outer clamping plate 5 and the outer locking member 4 are sequentially fitted onto the connector 31; finally, the inner locking member 7 and the outer locking member 4 are locked until the outer clamping plate 5 is positioned between the outer locking member 4 and the outer side of the module frame 2, and the inner clamping plate 6 is positioned between the inner locking member 7 and the inner side of the module frame 2. Under the joint support of the outer clamping plate 5 and the inner clamping plate 4, the supporting forces borne by the two ends of the connector 31 cancel each other out, preventing the module frame 2 from deforming due to excessive load, and ensuring that the support member 3 stably supports the module body 1.

[0052] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0053] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
