[0035] Please refer to Figs. 1 to 3 The embodiment provides a connection structure of a photovoltaic module and a photovoltaic cleaning robot walking bridge, which comprises a photovoltaic panel 10, a connecting bridge 20 and a module supporting plate 30. The connecting bridge 20 is arranged on one side of the photovoltaic panel 10, and there is a gap between the photovoltaic panel 10 and the connecting bridge 20. The module supporting plate 30 comprises a connecting bottom plate 31 and a fixing plate 32. The two ends of the connecting bottom plate 31 are arranged below the photovoltaic panel 10 and the connecting bridge 20 respectively, and one end of the connecting bottom plate 31 close to the connecting bridge 20 is connected with the connecting bridge 20. The fixing plate 32 is arranged above the connecting bottom plate 31, and there is a containing gap for containing the frame of the photovoltaic panel 10 between the fixing plate 32 and the connecting bottom plate 31. One end of the fixing plate 32 is connected with the end of the connecting bottom plate 31 away from the connecting bridge 20, and the length of the fixing plate 32 is less than the length of the connecting bottom plate 31.

[0036] In this embodiment, the connecting bridge 20 is arranged on one side of the photovoltaic panel 10, and a certain gap is reserved between the two, providing space for thermal expansion and contraction and slight displacement of the photovoltaic panel 10. The assembly support plate 30 is the core of the entire structure, composed of a connecting bottom plate 31 and a fixing plate 32. The two ends of the connecting bottom plate 31 are respectively placed below the photovoltaic panel 10 and the connecting bridge 20, and the end close to the connecting bridge 20 is directly connected with the bridge, ensuring the stability of the overall structure. The fixing plate 32 is located above the connecting bottom plate 31, and a gap is formed between the two for accommodating the frame of the photovoltaic panel 10. This design allows the frame of the photovoltaic panel 10 to be precisely embedded, achieving more secure fixation. One end of the fixing plate 32 is connected with the end of the connecting bottom plate 31 away from the connecting bridge 20, and the length of the fixing plate 32 is intentionally designed to be smaller than that of the connecting bottom plate 31. This asymmetric design has multiple advantages. First, it can better adapt to photovoltaic panels 10 of different specifications, improving the versatility of the connecting structure. Second, this design can reduce the deflection of the fixing plate 32 when under stress, improving the load-bearing capacity and stability of the overall structure. Through the scheme of this embodiment, not only can the photovoltaic panel 10 be effectively fixed, but also the slight displacement and stress brought by the external environment can be absorbed, ensuring the reliable operation of the photovoltaic power generation system in various complex environments.

[0037] Please refer to Fig. 1 In some embodiments, the cross section of the fixing plate 32 and the connecting bottom plate 31 is "U" shaped.

[0038] In this embodiment, the cross section of the fixing plate 32 and the connecting bottom plate 31 is "U" shaped, which has significant structural advantages, not only enhancing the overall strength of the assembly support plate 30, but also providing better space for clamping the frame of the photovoltaic panel 10. At the same time, through this design, the fixing plate 32 can more firmly wrap the connecting bottom plate 31, forming a more stable connecting structure. The open end of the "U" shaped cross section can conveniently accommodate the frame of the photovoltaic panel 10, while the edges on both sides can provide more uniform clamping pressure, ensuring that the photovoltaic panel 10 can be securely fixed, reducing displacement that may be caused by external vibration or environmental changes. The use of "U" shaped cross section design significantly improves the structural strength and stability of the assembly support plate 30, optimizes the fixation effect of the photovoltaic panel 10, and enhances the reliability and durability of the entire photovoltaic module connecting system.

[0039] In some embodiments, the fixing plate 32 and the connecting bottom plate 31 are parallel to each other.

[0040] In this embodiment, the fixed plate 32 and the connecting bottom plate 31 are arranged in parallel with each other. This parallel arrangement allows the fixed plate 32 to uniformly apply pressure to the frame of the photovoltaic panel 10, ensuring stable clamping of the photovoltaic panel 10 and optimizing the clamping effect of the photovoltaic panel 10. By maintaining the parallel relationship between the fixed plate 32 and the connecting bottom plate 31, the entire assembly tray 30 can achieve better mechanical properties, reduce the deviation and deformation caused by improper installation or external stress, enhance the stability and reliability of the connection, and enable the photovoltaic assembly to maintain high efficiency under various environmental conditions. On the other hand, this design simplifies the installation process, allowing operators to more easily position and secure the photovoltaic panel 10, improving work efficiency. In addition, the parallel arrangement makes the entire connection structure more compact, reducing the overall volume and helping to save space in the design.

[0041] In some embodiments, it further includes a reinforcing rib 40, which comprises a first reinforcing strip 41 and a second reinforcing strip 42. The first reinforcing strip 41 is placed on the connecting bottom plate 31, and the second reinforcing strip 42 is placed on the fixed plate 32. The first reinforcing strip 41 is connected to the second reinforcing strip 42 at one end, and the first reinforcing strip 41 and the second reinforcing strip 42 are integrally formed.

[0042] In this embodiment, to further enhance the stability and load-bearing capacity of the photovoltaic assembly and the bridge connection structure, a reinforcing rib 40 composed of a first reinforcing strip 41 and a second reinforcing strip 42 is designed on the assembly tray 30. The first reinforcing strip 41 placed on the connecting bottom plate 31 is connected to the second reinforcing strip 42 placed on the fixed plate 32, and both are designed in an integral molding scheme. This not only effectively disperses and transmits external forces, but also significantly improves the rigidity and anti-deformation capacity of the entire connection structure. The integrally formed reinforcing rib 40 can uniformly transmit and distribute stress when the photovoltaic panel 10 is subjected to wind, snow pressure or other external loads, reducing local stress concentration and the risk of material fatigue and potential structural failure. At the same time, the design of the reinforcing rib 40 also improves the overall stability of the assembly tray 30, enabling the photovoltaic assembly to maintain good performance and reliability under various complex environmental conditions. Through the arrangement of the first reinforcing strip 41 and the second reinforcing strip 42, not only the mechanical properties of the connection structure are enhanced, but also a strong structural guarantee is provided for the long-term stable operation of the photovoltaic power generation system.

[0043] In some embodiments, the connecting bottom plate 31 is provided with a first groove 311 on the side close to the fixed plate 32, the first groove 311 is provided opposite to the first reinforcing strip 41; the fixed part is provided with a second groove 321 on the side close to the connecting bottom plate 31, the second groove 321 is provided opposite to the second reinforcing strip 42; and the first groove 311 and the second groove 321 are in communication. It should be noted that the first through hole 312, the second through hole 21 and the reinforcing rib 40 are formed by die indentation forming; specifically, the first groove 311 and the second groove 321 are formed on the flat assembly support plate 30 by die indentation forming, at this time the first reinforcing strip 41 and the second reinforcing strip 42 will be formed away from the die indentation forming surface; and then the flat assembly support plate 30 is bent.

[0044] In the present embodiment, the reinforcing rib 40 of the connecting bottom plate 31 and the fixed plate 32 adopts a precise groove matching scheme, further optimizing the mechanical properties of the connecting structure. The connecting bottom plate 31 is provided with a first groove 311 on the side close to the fixed plate 32, the first groove 311 is provided opposite to the first reinforcing strip 41, forming a precise structural unit. At the same time, the fixed plate 32 is also provided with a second groove 321 on the side close to the connecting bottom plate 31, the second groove 321 corresponds to the second reinforcing strip 42, and the two grooves are formed by die indentation forming. Specifically, on the initial flat assembly support plate 30, the first groove 311 and the second groove 321 are formed at the specified position by die indentation forming process, during which the area away from the die indentation forming surface will naturally form the first reinforcing strip 41 and the second reinforcing strip 42. Subsequently, through the precise bending process, the originally flat assembly support plate 30 is shaped into the required final structure. Thus, the first groove 311 and the second groove 321 can perfectly communicate with each other, forming a continuous and coordinated reinforcing structure, at the same time, the mutual communication design of the first groove 311 and the second groove 321 can effectively disperse and transfer external load, optimize the stress transfer path, reduce local stress concentration and reduce the risk of material fatigue. The die indentation forming process of the first through hole 312, the second through hole 21 and the reinforcing rib 40 not only ensures the consistency and accuracy of the structure, but also significantly improves the overall strength and stability of the assembly support plate 30. Reducing stress concentration, improving the durability and reliability of the photovoltaic module and bridge connection structure. In summary, the scheme of the present embodiment realizes the integration of the reinforcing rib 40, significantly improves the overall strength and rigidity of the connecting structure, which is not only conducive to simplifying the production process, but also provides higher performance guarantee for the photovoltaic module and bridge connection structure.

[0045] In some embodiments, the reinforcing rib 40 is parallel to the extension direction of the assembly support plate 30.

[0046] In this embodiment, the reinforcing ribs 40 are arranged parallel to the extension direction of the assembly backboard 30, which ensures that the reinforcing ribs 40 can effectively share the external load with the assembly backboard 30, thereby enhancing the stability of the overall structure. By arranging the reinforcing ribs 40 parallel to the assembly backboard 30, the force transmission and distribution become more uniform, reducing the local stress concentration phenomenon. This layout also enables the connecting structure to resist bending and torsional deformation more effectively when subjected to external forces, improving the wind pressure and snow pressure resistance of the photovoltaic assembly. In addition, the parallel design simplifies the manufacturing process, helps to improve production efficiency and reduce costs, and provides a more solid foundation for the stable operation of the photovoltaic assembly.

[0047] Please refer to Fig. 2 and Fig. 3 In some embodiments, the connecting bottom plate 31 is provided with a first through hole 312, and the first through hole 312 is arranged below the connecting bridge 20; the connecting bridge 20 is provided with a second through hole 21, and the first through hole 312 and the second through hole 21 are arranged opposite to each other; the first through hole 312 and the second through hole 21 are used for the bolt to pass through, so as to lock the assembly backboard 30 on the connecting bridge 20. The first through hole 312 is preferably a waist-round through hole, so that the assembly backboard 30 can adapt to different gaps (i.e., the gap between the photovoltaic panel 10 and the connecting bridge 20); specifically, the first through hole 312 is a strip-shaped through hole, and when the gap is too wide, the bolt can pass through the side of the first through hole 312 away from the fixed plate 32.

[0048] In this embodiment, the through holes arranged opposite on the connecting bottom plate 31 and the connecting bridge 20 enhance the stability and firmness of the assembly backboard 30, ensuring the reliability of the photovoltaic assembly under various external loads. In design, the shape of the first through hole 312 is preferably waist-round, so as to provide greater gap adaptability and adjustment flexibility, ensuring that the bolt can smoothly pass through and fix the assembly backboard 30. Specifically, when the gap is too wide, the bolt can pass through the side of the first through hole 312 away from the fixed plate 32, which makes the installation process more convenient, reduces the strict requirements on installation accuracy, improves the installation efficiency, and also improves the adaptability of the overall structure, which can effectively cope with the position adjustment of the photovoltaic panel 10 due to environmental changes, is suitable for different installation conditions, and can effectively reduce potential problems caused by gap changes, providing a strong guarantee for the long-term operation of the photovoltaic power generation system.
