[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 5 As shown, an embodiment of the present invention provides a photovoltaic cabinet, which includes a cabinet body 10, a bracket assembly 20 and a photovoltaic assembly 30. The bracket assembly 20 is arranged on one side of the cabinet body 10 and the installation position on the side of the cabinet body 10 is adjustable. The photovoltaic assembly 30 is arranged on the bracket assembly 20 and the installation position on the bracket assembly 20 is adjustable so that the photovoltaic assembly 30 covers at least a portion of the top of the cabinet body 10.

[0036] The support assembly 20 is rotatably arranged to adjust the azimuth angle of the photovoltaic assembly 30 in the horizontal direction. The photovoltaic assembly 30 is installed on the support assembly 20, and the inclination angle of the photovoltaic assembly 30 in the vertical direction is adjustable.

[0037] The photovoltaic cabinet of this solution achieves flexible installation and multi-degree-of-freedom adjustment of the photovoltaic assembly 30 by adjusting the installation position of the bracket assembly 20 on one side of the cabinet body 10, rotating the bracket assembly 20, and adjusting the tilt angle of the photovoltaic assembly 30. Compared with the traditional fixed bracket for installing the photovoltaic assembly 30 on the side of the cabinet body 10, there is no need to customize the fixed bracket for each cabinet body 10 position as in the traditional installation of the photovoltaic assembly 30, which simplifies the installation process, shortens the construction period, and reduces costs. At the same time, it also improves the applicability of the photovoltaic assembly 30, making it adaptable to different regions, different outdoor cabinet body 10 positions, and different cabinet body 10 orientations, so that the photovoltaic assembly 30 can be adjusted to the optimal light receiving angle according to different environmental factors (geographic latitude, seasonal changes, etc.), thereby improving solar energy conversion efficiency and maximizing power generation. On the other hand, the photovoltaic assembly 30 covers at least a portion of the top of the cabinet body 10 to achieve at least partial shading of the top of the cabinet body 10, so that the photovoltaic assembly 30 can generate electricity while reducing the heat conduction caused by direct sunlight on the top of the cabinet body 10, which is conducive to energy saving.

[0038] In which, the photovoltaic cabinet also includes a first fastening component 41, and one side of the cabinet body 10 has multiple first transition areas distributed along the length direction and / or height direction of the cabinet body 10, and the bracket assembly 20 is detachably installed at one of the first transition areas through the first fastening component 41; or, the bracket assembly 20 is fixed at one of the first transition areas through the first fastening component 41.

[0039] Such an arrangement can realize the adjustment of the installation position of the bracket assembly 20 in the horizontal direction and the height direction. When the position of the photovoltaic component 30 needs to be adjusted, the first fastening component 41 is loosened or removed to loosen or disconnect the connection between the bracket assembly 20 and the cabinet body 10, and the bracket assembly 20 is moved to the new first transfer area and the first fastening component 41 is re-tightened to complete the adjustment of the installation position of the bracket assembly 20 and the position of the photovoltaic component 30. The first fastening component 41 is used to realize a flexible connection between the bracket assembly 20 and the cabinet body 10, which not only ensures the stability of the structure, but also provides the adjustability of the installation position, improves the adaptability and maintenance convenience of the photovoltaic cabinet, and can quickly and conveniently adjust the position of the photovoltaic component 30 without destroying the original structure.

[0040] Among them, multiple first transition areas are distributed in m rows and n columns, and the values ​​of m and n can be adjusted according to actual conditions. In this embodiment, one side of the cabinet body 10 has multiple first transition areas distributed along the length direction of the cabinet body 10, and the multiple first transition areas are spaced apart or at least partially overlapped. The installation height of the bracket assembly 20 in any first transition area is adjustable (it can be understood that the multiple first transition areas in this embodiment are distributed in 1 row and 3 columns, and the installation position of the bracket assembly 20 in the same column of first transition areas along the height direction is adjustable); any first transition area includes multiple first mounting points, and one side of the bracket assembly 20 has multiple second mounting points distributed along the circumference of the side. The multiple first mounting points of the same first transition area are detachably connected to the multiple second mounting points via the first fastening assembly 41. In this arrangement, through the matching connection of the multiple second mounting points with the multiple first mounting points, the bracket assembly 20 is accurately positioned and firmly fixed on the first transition area on the cabinet body 10, thereby enhancing the stability of the installation and the stability of the overall structure of the photovoltaic cabinet.

[0041] like Figures 1 to 4 As shown, the bracket assembly 20 includes a fixed bracket 21, which is mounted on one side of the cabinet body 10 and has an adjustable mounting position. The fixed bracket 21 comprises a rectangular frame 211 and a reinforcing beam 212 disposed within the area surrounding the rectangular frame 211. The rectangular frame 211 has multiple secondary mounting points for connecting to the cabinet body 10. These secondary mounting points are symmetrically distributed along the two frame beams along the width of the rectangular frame 211. This arrangement enhances the structural strength of the fixed bracket 21 through the reinforcing beam 212, while the symmetrically distributed secondary mounting points provide a stable connection to the cabinet body 10, thereby improving the overall structural stability of the photovoltaic cabinet and ensuring the safe operation of the photovoltaic modules even in extreme weather conditions.

[0042] In this embodiment, one side of the cabinet body 10 has 18 first mounting points, and the 18 first mounting points are arranged in 6 columns, each column includes 3 first mounting points, wherein the first mounting points in the two left columns form a first transfer area, the first mounting points in the middle two columns form a first transfer area, and the first mounting points in the two right columns form a first transfer area. The three first transfer areas are spaced apart in pairs, and the size of the rectangular frame 211 is adapted to one of the first transfer areas and has 6 second mounting points thereon. When the rectangular frame 211 is mounted directly on one of the first transfer areas, the 6 first mounting points pass through the first transfer area. A fastening assembly 41 is detachably connected to the six second mounting points in a one-to-one correspondence. When it is necessary to adjust the installation position of the rectangular frame 211 on the first transition area, the rectangular frame 211 only needs to be moved upward during installation. The two second mounting points at the top of the rectangular frame 211 protrude out of the largest area formed by all the first transition areas. The remaining four second mounting points of the rectangular frame 211 are detachably connected to the four first mounting points in the corresponding first transition areas in a one-to-one correspondence (i.e., there is no corresponding connection between the two second mounting points at the top of the rectangular frame 211 and the two first mounting points at the bottom of the first transition area).

[0043] Among them, in another embodiment not shown in the figure, the first transfer areas of two adjacent columns may also partially overlap, that is, the first transfer areas of the previous column and the first transfer areas of the next column share the same column of first installation points. Compared with the above embodiment, the number of first installation points in this embodiment is 12 (4 columns, 3 first installation points in each column), and at the same time, it can ensure the formation of three first transfer areas.

[0044] It should be noted that the size, shape, etc. of the rectangular frame 211, the number and distribution of the reinforcing beams 212, the number and distribution of the second installation points, the number and distribution of the first transfer areas, the number and distribution of the first installation points included in the first transfer area, etc. can all be adaptively adjusted according to actual conditions.

[0045] Preferably, the first fastening assembly 41 in this embodiment is an adapter seat and an adapter screw.

[0046] Optionally, the adjustment of the installation position of the bracket assembly 20 on one side of the cabinet body 10 can be achieved by other means on the basis of ensuring the stability of the photovoltaic assembly 30. For example, in other embodiments not shown in the figure, one side of the cabinet body 10 has a first slide rail passing through multiple first transition areas, and a first sliding member is correspondingly provided on the bracket assembly 20. One end of the first sliding member extends into the first slide rail and is slidably arranged to adjust the bracket assembly 20 to one of the first transition areas, and the first fastening assembly 41 is used to fix the bracket assembly 20 at one of the first transition areas. The bracket assembly 20 in this embodiment can be slidably installed on one side of the cabinet body 10 and tightened and loosened by the first fastening assembly 41. When the first fastening assembly 41 is loosened or removed, the bracket assembly 20 slides along the first slide rail to the required first transfer area, and then the first fastening assembly 41 is used to lock or restrict its sliding to complete the position adjustment. Through the cooperation of the first slide rail and the first sliding member, smooth movement on the side of the cabinet body 10 is achieved, which facilitates the rapid adjustment of the position of the bracket assembly 20, simplifies the installation and adjustment process of the photovoltaic module 30, and improves work efficiency. Among them, the structure and coordination of the first slide rail and the first sliding part can be adaptively designed according to actual conditions. It is only necessary to ensure that the first sliding part will not easily fall out or shift from the first slide rail. The selection of the first fastening component 41 and its relative tightness to the bracket component 20 and the cabinet body 10 can also be designed and adjusted according to actual conditions. For example, at least two second mounting holes are provided near each first transfer area, and the bracket component 20 has a corresponding number of first mounting holes. The first fastening component 41 is an adapter seat and an adapter screw. After sliding the bracket component 20 to the first transfer area to be installed, the connection between the two is achieved through multiple first fastening components 41 to avoid relative rotation and relative sliding between the two.

[0047] Specifically, the photovoltaic cabinet further includes a second fastening assembly 42 and a hinge assembly 44. The photovoltaic assembly 30 has a plurality of second transition regions distributed along the length and / or width of the photovoltaic assembly 30. The bracket assembly 20 is detachably hingedly mounted at one of the second transition regions via the hinge assembly 44 and the second fastening assembly 42. Alternatively, the bracket assembly 20 is hingedly mounted on the photovoltaic assembly 30 via the hinge assembly 44 and fixed at one of the second transition regions via the second fastening assembly 42. This arrangement allows for adjustment of the mounting position of the photovoltaic assembly 30 on the bracket assembly 20. The hinge assembly 44 is used to achieve a flexible connection between the photovoltaic assembly 30 and the bracket assembly 20, facilitating adjustment of the inclination of the photovoltaic assembly 30 according to the illumination angle. The second fastening assembly 42 is used to define the connection position of the photovoltaic assembly 30 on the bracket assembly 20, thereby ensuring the stability of the photovoltaic assembly.

[0048] The multiple second transition regions can also be arranged in m rows and n columns, with the values ​​of m and n being adjustable based on actual conditions. In this embodiment, the photovoltaic assembly 30 has multiple second transition regions distributed along the width of the photovoltaic assembly 30, with the multiple second transition regions spaced apart or at least partially overlapping. The mounting height of the support assembly 20 within any first transition region is adjustable (this can be understood as the multiple first transition regions in this embodiment being arranged in one row and three columns, and the mounting position of the support assembly 20 within the same column of first transition regions being adjustable in height). Any second transition region includes multiple third mounting points, and the top of the support assembly 20 has multiple fourth mounting points spaced apart along the same direction. The multiple third mounting points within the same second transition region are detachably connected to the corresponding multiple fourth mounting points via hinge assemblies 44 and second fastening assemblies 42. This arrangement enables precise mounting and angle adjustment of the photovoltaic assembly 30 on the support assembly 20 through the matching connection of the third and fourth mounting points and the transition of the hinge assembly 44, thereby enhancing the mounting accuracy and stability of the photovoltaic assembly 30.

[0049] Preferably, the position of the photovoltaic component 30 in the length direction within any second transition area is adjustable (it can be understood that the multiple second transition areas in this embodiment are distributed in 1 row and 2 columns, and the installation position of the bracket component 20 in the same column of the first transition area is adjustable along the length direction, where the row is the width direction and the column is the length direction).

[0050] like Figures 1 to 3As shown, the bracket assembly 20 also includes an angle adjustment bracket 22 and an elevation adjuster 23. The angle adjustment bracket 22 is arranged on the fixed bracket 21 and can be adjusted in rotation angle relative to the fixed bracket 21. The photovoltaic module 30 is hingedly connected to the angle adjustment bracket 22 via a hinge assembly 44 and a second fastening assembly 42 so that its installation position can be adjusted. One end of the elevation adjuster 23 is hingedly connected to the angle adjustment bracket 22, and the other end of the elevation adjuster 23 is slidably hingedly connected to the photovoltaic module 30 to adjust the inclination angle of the photovoltaic module 30. This arrangement allows the photovoltaic module 30 to be adjusted in all directions at an angle through the angle adjustment bracket 22 and the elevation adjuster 23 to adapt to different lighting conditions, thereby improving the power generation efficiency of the photovoltaic module 30 and achieving optimal light reception in various environments. The angle adjustment bracket 22 is an isosceles triangle structure, comprising a base frame 221, a support frame 223, and two symmetrical side frames 222. The two side frames 222 are connected to the base frame 221 end to end. One end of the support frame 223 is connected to the intersection of the two side frames 222, and the other end of the support frame 223 is connected to the middle position of the base frame 221. The side of the base frame 221 facing away from the support frame 223 has multiple fourth mounting points for connecting to the photovoltaic module 30. The multiple fourth mounting points are distributed at least at the transition point between the base frame 221 and one of the side frames 222, the transition point between the base frame 221 and the support frame 223, and the transition point between the base frame 221 and the other side frame 222. This arrangement utilizes the stability of the isosceles triangle structure to achieve secure fixation and angle adjustment of the photovoltaic module 30 through the multiple fourth mounting points, while facilitating the articulated rotation adjustment of the photovoltaic module 30, improving the installation accuracy and stability of the photovoltaic module 30, and enhancing the overall structural strength of the photovoltaic cabinet. On the other hand, photovoltaic assembly 30 includes a photovoltaic support 31 and a photovoltaic panel 32 mounted on photovoltaic support 31. The side of photovoltaic support 31 facing support assembly 20 has multiple rows of third mounting points for connecting to support assembly 20. These rows of third mounting points are spaced apart along the width of photovoltaic support 31, and support assembly 20 is hingedly connected to one of these rows of third mounting points. These multiple rows of third mounting points enable precise connection and angle adjustment between photovoltaic assembly 30 and support assembly 20, improving the installation accuracy and stability of photovoltaic assembly 30.

[0051] In this embodiment, the bottom of the photovoltaic bracket 31 has two long brackets 311 and three short brackets 312 spaced apart between the two long brackets 311. At least one third mounting point is formed in the middle of any short bracket 312, wherein the three short brackets 312 correspond to at least one group of second transition areas. The base frame 221 has three fourth mounting points. When the angle adjustment bracket 22 is directly opposite the second transition area installed on one of the photovoltaic brackets 31, the three fourth mounting points are detachably hinged to the three third mounting points of the same group of second transition areas via the hinge assembly 44 and the second fastening assembly 42. When it is necessary to adjust the installation position of the photovoltaic assembly 30 in the length direction of the second transition area, the photovoltaic bracket 31 only needs to be moved along the length direction of the base frame 221 during installation so that one of the third mounting points protrudes from the base frame 221, and the remaining two third mounting points are detachably hinged to the two fourth mounting points in the corresponding second transition areas.

[0052] Preferably, the short support 312 has a limiting slide 3121. The elevation angle adjuster 23 includes an adjustment rod and two adapters. The ends of the adjustment rod are hinged to the two adapters, one of which is mounted on the support frame 223, and the other is slidably mounted within the limiting slide 3121. The elevation angle adjuster 23 can adjust the inclination angle of the photovoltaic module 30 within a range of 10° to 30° relative to the horizontal plane. The number of photovoltaic panels 32 can be adaptively increased or decreased according to actual conditions.

[0053] It should be noted that the composition of the photovoltaic bracket 31, the selection and distribution of the third installation point and the second transfer area, the composition of the angle adjustment bracket 22, the selection and distribution of the fourth installation point, etc. can all be adaptively adjusted according to actual conditions, and examples are not given here one by one.

[0054] Preferably, the second fastening component 42 in this embodiment is a conversion screw, and the hinge component 44 is a hinge seat.

[0055] Optionally, the adjustment of the installation position of the photovoltaic component 30 on the bracket assembly 20 can also be achieved by other means. For example, in other embodiments not shown in the figure, on the basis of ensuring the stability of the photovoltaic component 30, one side of the cabinet body 10 has a second slide rail and a second sliding member slidably arranged in the second slide rail. The bracket assembly 20 is hinged to the second sliding member through the hinge assembly 44, and the second fastening assembly 42 is used to fix the bracket assembly 20 at one of the second transition areas.

[0056] The photovoltaic bracket 31 in this embodiment is slidably hingedly mounted on one side of the angle adjustment bracket 22 by a hinge assembly 44 and is tightened and loosened by a second fastening assembly 42. When the second fastening assembly 42 is loosened or disassembled, the photovoltaic bracket 31 can slide to the desired second transfer area, and then the second fastening assembly 42 is used to lock or restrict its sliding to complete the position adjustment. Through the cooperation of the second slide rail and the second sliding member, the smooth movement adjustment of the photovoltaic component 30 relative to the cabinet body 10 is achieved, thereby improving the flexibility and maintainability of the photovoltaic cabinet. Among them, the structure and cooperation of the second slide rail and the second sliding member, etc. can be adaptively designed according to actual conditions, and it is only necessary to ensure that the second sliding member will not easily fall out or deviate from the second slide rail. The selection of the second fastening assembly 42 and its relative tightening method for the photovoltaic component 30 and the angle adjustment bracket 22 can also be designed and adjusted according to actual conditions.

[0057] like Figures 1 to 3 As shown, the angle adjustment bracket 22 also includes an adapter plate 224 arranged at the connection position between the two side frames 222 and the support frame 223, the fixed bracket 21 includes an adapter seat 213 located at the top of the fixed bracket 21, and the photovoltaic cabinet also includes a third fastening component 43. The adapter plate 224 has multiple fifth mounting points distributed along the circumference, and the adapter seat 213 has multiple sixth mounting points distributed along the circumference. The multiple fifth mounting points are detachably connected to the multiple sixth mounting points in a one-to-one correspondence through the third fastening component 43. In this arrangement, the flexible connection and angle adjustment between the angle adjustment bracket 22 and the fixed bracket 21 are achieved through the cooperation of the adapter plate 224 and the adapter seat 213. The third fastening component 43 is used to lock this connection state, thereby improving the flexibility and maintainability of the photovoltaic cabinet and enabling the position and angle of the photovoltaic component to be quickly adjusted without destroying the original structure. Preferably, the third fastening component 43 is a fastening screw.
