[0045] As Figures 1 to 5 shown, an embodiment of the first aspect of this application provides a photovoltaic power supply system support assembly 1, including a support bracket 11 for carrying a photovoltaic power generation panel 21 and a battery compartment 12. The support bracket 11 is disposed on the battery compartment 12, and a long strip-shaped fixing hole 121 is formed on the cabin wall of the battery compartment 12; a fixing member 13 is inserted through the long strip-shaped fixing hole 121 to be connected to the support bracket 11 and generate a pulling force on the support bracket 11; the long strip-shaped fixing hole 121 is adapted to provide at least two installation positions for a single fixing member 13.

[0046] The photovoltaic power generation panel 21 is a device that can convert solar radiant energy into electrical energy. It is usually composed of multiple solar cell units, and these units work based on the photovoltaic effect. The photovoltaic power generation panel 21 has the ability to generate electricity by itself and can generate electricity without an external power source. This electrical energy can be applied to homes, commercial and industrial sites, outdoor lighting, road lighting, etc., and can also be used as an emergency backup power source to provide power during natural disasters or power outages. The photovoltaic power generation panel 21 usually includes monocrystalline silicon photovoltaic panels, polycrystalline silicon photovoltaic panels, thin-film photovoltaic panels, etc. The electrical energy generated by the photovoltaic power generation panel 21 can be stored in a battery 22, and the battery 22 then provides electrical energy to an electrical device 23.

[0047] In the embodiments of the present application, there are various types of fixing members 13. Specifically, bolts can be used. The bolts are used in cooperation with nuts, and the support bracket 11 can be tightened by tightening the nuts to make it closely fit the battery compartment 12. Rivets can also be used. One end of the rivet passes through the long strip-shaped fixing hole 121 and is connected to the support bracket 11, and the other end is fixed by a tightening tool to generate a pulling force.

[0048] The long strip-shaped fixing hole 121 can provide at least two installation positions for a single fixing member 13. Therefore, the fixing member 13 can be fixed at different positions in the long strip-shaped fixing hole 121. When it is necessary to adjust the angle or position of the photovoltaic panel 21, the fixing member 13 can be loosened, the support bracket 11 and the fixing member 13 can be adjusted to the preset position, and then fastened to realize the adjustment of the position and angle of the photovoltaic panel 21.

[0049] According to the photovoltaic power supply system support assembly 1 provided by the first aspect embodiment of the present application, the support bracket 11 is used to carry the photovoltaic panel 21, and the battery compartment 12 is used to accommodate the battery 22 and other necessary electrical components, such as a control system. A long strip-shaped fixing hole 121 is formed on the cabin wall of the battery compartment 12. When installing the support bracket 11, the installation part of the support bracket 11 is aligned with the position where the long strip-shaped fixing hole 121 is located, and then the fixing member 13 is passed through the long strip-shaped fixing hole 121 and connected to the support bracket 11. The fixing member 13 pulls the support bracket 11 to make it closely adhere to the cabin wall of the battery compartment 12 to realize the fixation of the support bracket 11. This fixing method does not require the assistance of inner and outer sleeves, and the connection between the support bracket 11 and the battery compartment 12 can be realized only through the fixing member 13, which simplifies the installation steps, improves the installation efficiency, simplifies the connection structure, saves costs, and the fixing member 13 performs a pulling type fastening on the support bracket 11, with strong fastening force and good fastening effect, improving the stability of the connection structure. Further, the long strip-shaped fixing hole 121 can provide at least two installation positions for a single fixing member 13, which means that the support bracket 11 can be installed at different positions in the long strip-shaped fixing hole 121 through the fixing member 13, so as to realize the fine adjustment of the installation position and angular position of the support bracket 11, enhancing the adaptability and flexibility of the support bracket 11. In summary, the photovoltaic power supply system support assembly 1 provided by the first aspect embodiment of the present application improves the flexibility and stability of the structure, simplifies the installation process, reduces costs, and also improves the safety of the photovoltaic power supply system 2.

[0050] Such as Figures 2 to 3As shown, in some embodiments of the present application, the elongated fixing holes 121 are arc-shaped, and three elongated fixing holes 121 are provided and are distributed in a surrounding manner. The arc-shaped design can better adapt to the installation requirements of the supporting bracket 11 at different angles, thereby ensuring that the supporting bracket 11 can be stably connected to the battery compartment 12, increasing the installation flexibility, allowing the supporting bracket 11 to adjust the angle within a certain range to optimize the sunlight receiving angle of the photovoltaic panel 21. The design of the three fixing holes can provide a more uniform force distribution, thereby improving the stability and reliability of the overall structure. Compared with a single or two fixing holes, the three fixing holes can provide better balance and stability, reducing structural distortion caused by wind loads or other external factors. Based on the above structure, installers can easily adjust the position and angle of the supporting bracket 11 without complex tools or additional adjustment components, thus simplifying the installation process.

[0051] As Figures 1 to 2 shown, in some embodiments of the present application, the supporting bracket 11 includes a first main body portion 111 and a second main body portion 112; the first main body portion 111 is connected to the battery compartment 12 through a fixing member 13, and the second main body portion 112 is rotatably connected to the first main body portion 111, and the second main body portion 112 is adapted to carry the photovoltaic panel 21. The second main body portion 112 is connected to the first main body portion 111 in a rotatable connection manner, and the elevation angle of the photovoltaic panel 21 can be adjusted and adjusted according to the angle of the sun, thereby improving the power generation efficiency.

[0052] Based on the above structure, the horizontal rotation of the first main body portion 111 can be realized through the elongated fixing holes 121, that is, the horizontal rotation of the photovoltaic panel 21 can be realized. Then, the rotation of the second main body portion 112 can realize the adjustment of the elevation angle of the photovoltaic panel 21, thereby realizing the all-round and multi-angle adjustment of the photovoltaic panel 21 to adapt to different lighting conditions and ensure the power generation efficiency.

[0053] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, in some embodiments of the present application, the battery compartment 12 includes a compartment body 122 and a compartment cover 123 covering the compartment body 122. An accommodation cavity 1221 adapted to accommodate the battery 22 is formed inside the compartment body 122; a fitting wall 1231 connected to the side wall of the accommodation cavity 1221 is formed on the compartment cover 123. The accommodation cavity 1221 formed inside the compartment body 122 can ensure that the battery 22 can be safely placed. The compartment cover 123 is closed on the compartment body 122, and the fitting wall 1231 fits with the inner side wall of the accommodation cavity 1221 to form a sealing structure to prevent moisture, dust, etc. from entering the compartment body 122 and protect the internal battery 22 and other electrical components from the external environment. The fitting wall 1231 is formed on the compartment cover 123 and connected to the inner side wall of the accommodation cavity 1221, which helps to ensure a tight connection between the compartment cover 123 and the compartment body 122 and provides a more robust closed structure at the same time.

[0054] As Figure 1 , Figures 4 to 5 As shown, in some embodiments of the present application, a bending portion 12311 is formed on the fitting wall 1231, and the bending portion 12311 is adapted to shield the connecting components at the connection. The design of the bending portion 12311 can hide the connecting components, avoid contact between the connecting components and the battery 22, protect the battery 22, and also make the overall appearance neater and more beautiful. In addition, shielding the connecting components can also prevent accidental contact, reduce the risk of electric shock, reduce the chance of external substances entering the interior of the accommodation cavity 1221, and reduce the possibility of corrosion and short circuit.

[0055] In some embodiments of the present application, the distance between the bending portion 12311 and the bottom wall of the accommodation cavity 1221 is greater than or equal to the thickness of the battery 22. By ensuring that the distance between the bending portion 12311 and the bottom wall of the accommodation cavity 1221 is greater than or equal to the thickness of the battery 22, it can effectively prevent the battery 22 from contacting the connecting components during and after installation, thus avoiding short circuits or other electrical failures.

[0056] As Figure 1 , Figures 4 to 5 As shown, in some embodiments of the present application, the connecting component is a screw 14, and screw holes adapted for the screw 14 to pass through are formed on both the fitting wall 1231 and the side wall of the accommodation cavity 1221; the length of the screw 14 is less than the extension length of the bending portion 12311. The length of the screw 14 being less than the extension length of the bending portion 12311 can prevent the screw 14 from protruding and reduce the safety hazard caused by accidental contact with the battery 22.

[0057] It should be noted that the figure shows a schematic structural diagram of the hatch cover 123 and the cabin body 122 in a disassembled state. At this time, the screw 14 is directly attached to the screw hole on the fitting wall 1231 for easy storage and to prevent the loss of the screw 14. When installing the hatch cover 123 onto the cabin body 122, the screw 14 passes through the screw hole on the side wall of the accommodation cavity 1221 of the cabin body 122 from the outside and then passes through the screw hole on the fitting wall 1231 of the hatch cover 123 to achieve fixation.

[0058] As Figures 1 to 2 shown, in some embodiments of the present application, the photovoltaic power supply system support assembly 1 further includes a fixing plate 15, and the fixing plate 15 is disposed on the first end face of the battery compartment 12; the battery compartment 12 is connected to the outer wall surface for installing the photovoltaic power supply system 2 through the fixing plate 15. With the help of the fixing plate 15, the photovoltaic power supply system support assembly 1 can be flexibly installed on different outer wall surfaces, whether it is on the roof, wall, utility pole or other positions. Through the connection between the fixing plate 15 and the installation surface, the stability of the photovoltaic power supply system 2 under various climatic conditions can be ensured, especially in areas with strong winds.

[0059] Furthermore, the fixing plate 15 can be made of corrosion-resistant and high-strength materials such as stainless steel, aluminum alloy, and galvanized steel.

[0060] As Figures 1 to 2 shown, in some embodiments of the present application, the photovoltaic power supply system support assembly 1 further includes a support frame 16 for electrical equipment; the support frame 16 for electrical equipment is disposed on the second end face of the battery compartment 12. The support frame 16 for electrical equipment can be connected to the battery compartment 12 by means of welding, bolt fixation, etc. to ensure stability. The electrical equipment 23 can be a camera, street lamp, etc.

[0061] As Figures 6 to 7 shown, the second aspect embodiment of the present application provides a photovoltaic power supply system 2, including: a photovoltaic power generation panel 21, a battery 22, an electrical equipment 23, and the photovoltaic power supply system support assembly 1 in any embodiment of the first aspect above; the photovoltaic power generation panel 21, the battery 22, and the electrical equipment 23 are all installed on the photovoltaic power supply system support assembly 1; the photovoltaic power generation panel 21 is suitable for generating electricity, and the battery 22 is suitable for storing the electric energy generated by the photovoltaic power generation panel 21 and providing electric energy for the electrical equipment 23.
