[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] like Figures 1 to 16 As shown, the present invention provides a frame structure, including a frame 10; a support rod 20, the support rod 20 is located in the frame 10; a plurality of junction boxes 30, the plurality of junction boxes 30 are arranged in sequence and spaced in the support rod 20 along the extension direction of the support rod 20, and two adjacent junction boxes 30 are connected by a wire 40; the inner wall of the support rod 20 is provided with a plurality of grooves 21, the plurality of junction boxes 30 are installed in the plurality of grooves 21 in a one-to-one correspondence, and each junction box 30 is interference fit with the corresponding groove 21; a plurality of elastic lock buckles 50, both ends of the support rod 20 are connected to the frame 10 by at least one elastic lock buckle 50; each elastic lock buckle 50 is detachably connected to the support rod 20.

[0048] It can be seen that the frame structure of the present invention not only provides a support rod 20, and arranges multiple junction boxes 30 in sequence along the extension direction of the support rod 20, and uses the groove 21 on the inner wall of the support rod 20 to install the junction box 30, thereby avoiding the installation method of the prior art of pasting the junction box 30 on the back of the panel, improving the installation method of the junction box 30, reducing the additional increase in the thickness of the photovoltaic module, and shortening the length of the wire 40, reducing material costs, and improving production efficiency; the arrangement of the support rod 20 can enhance the heat dissipation of the heating element inside the junction box 30. Compared with the traditional design that only relies on potting glue for heat conduction, the heat dissipation efficiency of the present invention is higher, which is conducive to the long-term stable operation of the junction box 30; and by using between two adjacent junction boxes 30 The wire 40 connection solves the problem of the need for additional leads for connection of the intermediate junction box 30 in the prior art, simplifies the electrical connection between the junction boxes 30, and makes the installation and maintenance of the junction boxes 30 more convenient; the elastic lock 50 is also provided to provide flexibility and stability for the connection between the support rod 20 and the frame 10, and a plurality of elastic locks 50 detachably connected to the support rod 20 are provided, making the frame structure more convenient to install or adjust, ensuring the structural stability of the component during transportation and installation, preventing the support rod 20 from falling off, enhancing the reliability of the frame structure, and improving the efficiency and service life of the photovoltaic component, effectively solving the problem of poor structural stability of the photovoltaic component and poor heat dissipation effect of the junction box thereon in the prior art.

[0049] like Fig.11 As shown, the closed end 51 of the elastic lock 50 includes a plurality of elastic arms 52 , and the elastic arms 52 are provided with locking points 53 for locking with the support rod 20 , and the locking points 53 may be hook-shaped or buckle-shaped structures.

[0050] The beneficial effects of designing the elasticity of the elastic arm 52 and the locking point 53 are as follows:

[0051] 1. The elastic lock 50 can be firmly locked on the support rod 20 without the need for additional tools or fasteners. This design not only simplifies the installation process and improves the efficiency of module assembly, but also due to the special shape of the locking point 53, even when the photovoltaic module is subjected to external vibration or impact, the connection between the junction box 30 and the support rod 20 and the frame 10 is still stable, reducing the risk of the junction box 30 falling off and enhancing the reliability of the photovoltaic module in harsh environments.

[0052] 2. The hook-shaped or buckle-shaped locking point 53 of the elastic lock 50 makes the installation and removal of the support rod 20 very simple, and the operation can be completed by applying appropriate pressure or tension, without the need for additional tools or complicated steps. This not only reduces the time cost of on-site installation and maintenance of photovoltaic modules, but also improves the maintainability of photovoltaic modules, facilitates the rapid replacement or inspection of faulty components, thereby improving the overall operating efficiency of photovoltaic modules and the flexibility of on-site applications.

[0053] 3. The locking point 53 on the elastic arm 52 cooperates with the support rod 20, providing a more reliable mechanical connection method than traditional bonding or screw connection. The elastic arm 52 can adapt to slight deformation, ensuring that the connection between the frame 10 and the support rod 20 remains tight even under natural conditions such as temperature changes, wind loads or snow loads, thereby improving the structural stability and durability of the photovoltaic module.

[0054] like Figure 6 , Fig. 9 and Fig.10 As shown, the locking point 53 is a plug-in protrusion 54 set on the elastic arm 52, and the end of the support rod 20 is provided with a plug-in hole 22 for the closed end 51 to be inserted, and the hole wall of the plug-in hole 22 is provided with a plug-in groove 23 for plugging and matching with the plug-in protrusion 54. The matching design of the plug-in protrusion 54 and the plug-in groove 23 provides precise positioning and a stable locking effect. During assembly, it is only necessary to align the closed end 51 of the elastic lock buckle 50 with the plug-in hole 22 of the support rod 20, and gently apply force to achieve installation and locking, without the need for additional tools or complicated operations; and during disassembly, it is also only necessary to apply force to the locking point 53 of the elastic lock buckle 50, so that the elastic lock buckle 50 and the support rod 20 can be easily separated, which is convenient for the rapid installation and maintenance of the photovoltaic module.

[0055] like Fig.11 and Fig.12 As shown, the open end 55 of the elastic lock buckle 50 is welded to the frame 10, so that the connection between the elastic lock buckle 50 and the support rod 20 is extremely stable and can withstand a large mechanical load.

[0056] Specifically, two connecting plates 56 are disposed at the bottom of the opening end 55 , and the elastic lock buckle 50 is connected to the frame 10 by welding through the connecting plates 56 .

[0057] like Fig.13 and Fig.14 As shown, the open end 55 of the elastic lock 50 is connected to the frame 10 via a fastener 80. The fastener connection method allows the position of the components to be fine-tuned during the assembly process to ensure accurate installation of the components.

[0058] Specifically, the elastic lock buckle 50 further includes two connecting plates 56 , each of which is provided with a through hole 57 , and one end of the fastener 80 passes through the through hole 57 and is connected to the frame 10 to fasten the elastic lock buckle 50 and the frame 10 .

[0059] like Fig.15 and Fig.16 As shown, the open end 55 of the elastic lock 50 is snap-connected with the frame 10, and the connection between the elastic lock and the support rod is achieved by designing a snap or a slot, which can be operated without tools, reducing complexity.

[0060] Specifically, the side walls of each connecting plate 56 of the elastic lock buckle 50 are also provided with a snap-in plate body 58, and the frame 10 is provided with a snap-in hole corresponding to the plug-in plate body 58. The elastic lock buckle 50 and the frame 10 are snap-fitted together through the snap-in plate body 58 and the snap-in hole.

[0061] Optionally, the open end 55 of the elastic lock buckle 50 and the frame 10 may be bonded together. The bonding connection can reduce the risk of corrosion at the metal contact point and extend the service life of the component.

[0062] like Figure 2 , Figure 7 , Figure 8 As shown, the frame structure also includes a wire buckle 60, which is arranged on the support rod 20 to fix the wire 40. The arrangement of the wire buckle 60 can effectively fix and manage the wire 40, avoid the random movement and entanglement of the wire inside the assembly, reduce the probability of short circuit and line failure, and improve the safety performance of the photovoltaic assembly; it helps to maintain the stability of the connection between the junction box 30 and the wire, and reduces the risk of photovoltaic assembly failure caused by loose or broken wires.

[0063] like Figure 8 As shown, the wire clip 60 includes a clipping portion 61 and a connecting portion 62 connected to each other, the clipping portion 61 is provided with a wire groove 63 for the wire 40 to cooperate with, and the connecting portion 62 is connected to the support rod 20. By fixing the wire 40 in the wire groove 63 of the wire clip 60, direct contact between the wire 40 and the junction box 30 or other heat-generating components can be avoided, which helps to improve air flow, reduce heat accumulation, reduce the operating temperature of the entire photovoltaic module, and improve the efficiency and life of the photovoltaic module.

[0064] Optionally, the connection portion 62 is welded to the support rod 20, providing a more stable fixing method and enhancing the mechanical strength and durability of the entire frame structure;

[0065] Optionally, the connecting portion 62 includes an external threaded section, and the support rod 20 is provided with an internal threaded hole for threaded connection with the external threaded section. The threaded connection allows the wire clip 60 to be detachably arranged between the support rod 20, and can be quickly disassembled and reinstalled when maintenance or replacement of the wire is required, thereby improving the flexibility of the photovoltaic module.

[0066] like Figure 8 As shown, the connecting portion 62 includes an elastic hook 64, and the support rod 20 is provided with a snap-in groove 24 for snapping with the elastic hook 64. The use of the elastic hook 64 simplifies the installation process of the wire buckle 60, so that the installation can be carried out quickly and without tools, reducing the complexity and cost of on-site installation.

[0067] like Figures 3 to 6 As shown, a wire avoidance groove 25 is provided between two adjacent grooves 21 on the support rod 20, and both ends of the wire avoidance groove 25 are respectively connected to the corresponding two grooves 21. The existence of the wire avoidance groove 25 optimizes the air circulation inside the support rod 20, helps the heat dissipation of the junction box 30 and the wire 40, reduces the internal temperature of the junction box 30 and the wire 40, thereby improving the stability of the electrical components in the junction box 30 and the efficiency of the photovoltaic module. At the same time, the installer can complete the wiring and fixing of the wire 40 more quickly, reducing the installation time and complexity.

[0068] like Figure 2 and Figure 7 As shown, the frame structure further includes two plug connectors 70, which are respectively connected to the first junction box 30 and the last junction box 30 of the plurality of junction boxes 30. By connecting the plug connector 70 with the junction box 30, there is no need to perform complicated electrical wiring outside the module, which simplifies the electrical connection process of the photovoltaic module, makes the assembly and on-site installation of the module easier and faster, reduces the installation cost and time, reduces electrical faults caused by loose wiring or poor contact, ensures the stable operation of the photovoltaic module under various environmental conditions, and improves the overall reliability of the photovoltaic module.

[0069] The present invention also provides a photovoltaic assembly, comprising the above-mentioned frame structure.

[0070] The beneficial effects of the framework structure of the present invention are as follows:

[0071] 1. Improve the overall structural stability and durability: By placing the junction box 30 in the groove 21 in the support rod 20 and using the elastic lock 50 to connect the frame 10 and the support rod 20, the overall structure of the photovoltaic module is more stable and can effectively resist the impact and influence of the external environment, such as wind, snow, temperature changes, etc., thereby extending the service life of the photovoltaic module.

[0072] 2. Enhance heat dissipation performance to ensure efficient operation of components: Place the junction box 30 inside the support rod. The support rod 20 serves as a good heat dissipation path, which can effectively guide the heat generated by the electronic components inside the junction box 30, avoid performance degradation or damage due to overheating, and improve the heat dissipation effect and long-term operation stability of the photovoltaic module.

[0073] 3. Optimize wire management and reduce failure rate: By arranging the wire buckle 60 and the wire avoidance groove 25 on the support rod 20, the wire 40 can be fixed and wired in an orderly manner, reducing the risk of confusion and short circuit of the wire 40, and improving the electrical safety and operation efficiency of the component.

[0074] 4. Simplify installation and maintenance and reduce operating costs: The detachable design of the elastic lock 50 and the use of the plug connector 70 make the installation and maintenance of the photovoltaic module quick and simple, without the need for complex tools or professional knowledge, thereby reducing the time and cost of on-site operations and improving the maintainability and flexibility of the module.
