[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a photovoltaic system is provided, including a photovoltaic module 10, a base bracket 20, a support component 30, and a locking member 40. The base bracket 20 is rotatably connected to a first end of the photovoltaic module 10 along a first direction X, and a groove 21 is formed on at least one side of the base bracket 20 along a second direction Y. At least one support component 30 is provided, and the support component 30 is correspondingly provided with the groove 21. The first end of the support component 30 is rotatably connected to a second end of the photovoltaic module 10 along the first direction X, and the second end of the support component 30 is slidably disposed in the groove 21. A through hole is provided on the second end of the support component 30. The locking member 40 passes through the through hole and is provided corresponding to the groove 21. The photovoltaic system has an adjustment state and a fixed state. In the adjustment state, the locking member 40 is spaced apart from the groove 21, and in the fixed state, the locking member 40 abuts against the groove 21.

[0039] In the photovoltaic system of this embodiment, the photovoltaic module 10, the base bracket 20, the support component 30 and the locking component 40 can be pre-assembled into a whole. By slidably setting the second end of the support component 30 in the groove 21, the photovoltaic module 10 can be quickly unfolded and stored. The installation and adjustment are convenient and can be completed by hand, with high installation efficiency.

[0040] Specifically, such as Figure 1 As shown, there are two support components 30 and two slides 21 to ensure stable support for the photovoltaic module 10.

[0041] Of course, in other alternative embodiments, the number of support components 30 and slides 21 can be adjusted according to the actual situation.

[0042] It should be noted that in related technologies, if the installation angle of a photovoltaic system needs to be adjusted, a lot of disassembly and installation work is required, which makes the operation cumbersome for individual users and is very unfriendly to individual users who want to install it themselves.

[0043] Therefore, in this embodiment, the second end of the support component 30 is slidably disposed in the slide groove 21. When adjustment is required, it is only necessary to loosen the locking member 40, adjust the position of the second end of the support component 30 in the slide groove 21, and then tighten the locking member 40 again to complete the adjustment of the photovoltaic system angle.

[0044] In one embodiment, such as Figure 1 As shown, the support assembly 30 includes a first support member 31 and a second support member 32. A cavity 311 is formed within the first support member 31. The second support member 32 is retractably disposed within the cavity 311. A through hole is provided at the end of the first support member 31 away from the cavity 311. The second support member 32 is rotatably connected to the second end of the photovoltaic module 10 along the first direction X. The retractable placement of the second support member 32 within the cavity 311 facilitates adjustment of the angle between the photovoltaic module 10 and the ground, adapting to the tilt angle requirements of different regions and ensuring the utilization rate of sunlight.

[0045] Furthermore, such as Figure 1 and Figure 4 As shown, the support assembly 30 also includes a pin 33. The first support member 31 has a first through hole 312, and the second support member 32 has a plurality of second through holes 321 spaced apart. In the fixed state, the pin 33 is arranged to pass through the first through hole 312 and the second through hole 321 in sequence.

[0046] For details, please refer to Figure 10 The second support member 32 has four second through holes 321 spaced apart, meaning that the support component 30 in this embodiment has four levels of adjustment.

[0047] Of course, in other alternative embodiments, the number of second through holes 321 on the second support member 32 can be adjusted according to the actual situation.

[0048] Of course, in other alternative embodiments, a second through hole 321 can be provided on the second support member 32, and a plurality of first through holes 312 can be opened at intervals on the first support member 31 to realize multi-level adjustment of the support component 30.

[0049] In one embodiment, such as Figure 11 As shown, along the extending direction of the support assembly 30, the projected area of ​​the second support member 32 is smaller than the projected area of ​​the cavity 311. At least a portion of the outer wall of the second support member 32 is spaced apart from the cavity wall of its corresponding cavity 311, and the spacing distance is A, satisfying 0.2mm≤A≤1mm. The smaller projected area of ​​the second support member 32 compared to the cavity 311 allows the second support member 32 to move freely and smoothly within the cavity 311. By limiting the spacing distance, excessive gaps are prevented from causing the second support member 32 to sway within the cavity 311.

[0050] Specifically, such as Figure 11 As shown, the cross-sections of the first support member 31 and the second support member 32 are both rectangular, and the outer walls of the second support member 32 are spaced apart from the cavity walls of the cavity 311.

[0051] It should be noted that when A < 0.2 mm, the distance between the outer wall of the second support member 32 and the cavity wall of its corresponding cavity 311 is small, which can easily cause jamming when adjusting the height of the second support member 32; when A > 1 mm, the distance between the outer wall of the second support member 32 and the cavity wall of its corresponding cavity 311 is too large, and the second support member 32 will shake in the cavity 311, resulting in a decrease in the overall stability of the support assembly 30.

[0052] Of course, in other alternative embodiments, the outer wall of the first support member 31 may also have one, two, or three sides spaced apart from the cavity wall of the cavity 311; or, the cross-sections of the first support member 31 and the second support member 32 may also be circular or other shapes.

[0053] Furthermore, such as Figure 2 As shown, the photovoltaic system also includes hinges 50, with at least two hinges 50. One side of each hinge 50 is connected to the base bracket 20, and the other side of each hinge 50 is connected to the first end of the photovoltaic module 10 along the first direction X. The hinges 50 enable a rotatable connection between the base bracket 20 and the photovoltaic module 10, resulting in a simple structure and convenient installation.

[0054] Specifically, such as Figure 2 As shown, there are three hinges spaced 50 apart.

[0055] Of course, in other alternative embodiments, the number of hinges 50 can also be adjusted and selected according to actual circumstances.

[0056] Furthermore, as Figure 6 and Figure 7 shown, the photovoltaic system further includes a ballast plate 60. The ballast plate 60 is detachably connected to the base bracket 20. In the fixed state, the ballast plate 60 is pressed against the side of the base bracket 20 away from the ground. Installing the ballast plate 60 on the base bracket 20 in the fixed state improves the overall wind resistance of the photovoltaic system.

[0057] Specifically, as Figure 6 shown, two ballast plates 60 are provided. The two ballast plates 60 are respectively pressed on two longitudinal beams 22 to firmly press the base bracket 20 on the ground.

[0058] Of course, in other alternative embodiments, the number of ballast plates 60 can be adjusted according to actual needs.

[0059] In one embodiment, as Figure 1 and Figure 2 shown, the base bracket 20 includes longitudinal beams 22 and cross beams 23. At least two cross beams 23 are arranged at intervals along the first direction X, and at least two longitudinal beams 22 are arranged at intervals along the second direction Y. Both ends of the longitudinal beam 22 are respectively connected to two cross beams 23, and a chute 21 is formed on the longitudinal beam 22.

[0060] Specifically, as Figure 1 shown, two longitudinal beams 22 and two cross beams 23 are provided. Both ends of the cross beam 23 are respectively connected to the ends of the same side of the two longitudinally arranged longitudinal beams 22 at intervals to enclose a "mouth" shape.

[0061] In other alternative embodiments, the number of longitudinal beams 22 and cross beams 23 can be increased according to actual circumstances to improve the overall strength of the base bracket 20.

[0062] Furthermore, a cavity 311 is formed inside the cross beam 23. As Figure 1 shown, the base bracket 20 further includes a cover 24. The cover 24 is arranged at the opening of the cavity 311. The cavity 311 is provided inside the cross beam 23 to reduce the overall weight of the base bracket 20; and the cover 24 is used to block the opening to prevent foreign objects from entering and improve the waterproof ability.

[0063] Specifically, as Figure 8 shown, the cross-section of the longitudinal beam 22 is "concave" shaped. A nut is embedded in the chute 21. The nut can slide in the chute 21. The locking member 40 is a bolt. The bolt is embedded in the nut and locked in the chute 21 to fix the support assembly 30 on the base bracket 20.

[0064] In one embodiment, such as Figures 1 to 7 As shown, the photovoltaic module 10 includes a photovoltaic panel (not shown) and a photovoltaic bracket 11. The photovoltaic panel is disposed on the photovoltaic bracket 11. The base bracket 20 is rotatably connected to the first end of the photovoltaic bracket 11 along the first direction X. The first end of the support component 30 is rotatably connected to the second end of the photovoltaic bracket 11 along the first direction X.

[0065] In one embodiment, such as Figure 7 As shown, the photovoltaic system also includes a micro-inverter 70, which is mounted on the photovoltaic support 11 and electrically connected to the photovoltaic module 10. The micro-inverter 70 is suitable for connection to the socket battery cell. The photovoltaic system achieves grid connection between the photovoltaic module 10 and the household circuit through the micro-inverter 70, and has a simple structure and is easy to install.

[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
