[0031] See also Figure 1 , Figure 2 and Figure 3 The photovoltaic awning 100 of the embodiment of the utility model includes a bracket 10 and a photovoltaic panel 20. The bracket 10 includes a base 11 and a support column 12. The upper surface 21 of the base 11 is provided with a plurality of first positioning structures 110, and the plurality of first positioning structures 110 are arranged at intervals. One end of the support column 12 is provided with a second positioning structure 120 that matches the first positioning structure 110 one by one; the photovoltaic panel 20 is arranged at the other end of the support column 12.

[0032] In the photovoltaic awning 100 of the utility model embodiment, a plurality of first positioning structures 110 are arranged on the base 11, and a second positioning structure 120 cooperating therewith is arranged at one end of the support column 12. This enables the position of the support column 12 to be effectively positioned during the installation process, thereby reducing uncertainty and errors during installation, so that one end of the support column 12 can be accurately installed at a predetermined position.

[0033] Specifically, the photovoltaic awning 100 can be made of materials such as metal or plastic, and can resist external environmental factors such as wind, rain, snow, etc. The photovoltaic awning 100 can be applied to areas such as the periphery of outdoor public and large commercial facilities or the courtyard of a private residence.

[0034] The bracket 10 is a structure for supporting and fixing the photovoltaic panel 20. The bracket 10 can be made of metal or other high-strength materials. The bracket 10 can provide a mounting base for the photovoltaic panel 20, so that the photovoltaic panel 20 can operate stably. There can be multiple brackets 10, and multiple brackets 10 can support the photovoltaic panel 20 at different supporting points, thereby improving the stability of the photovoltaic panel 20. The lengths of the brackets 10 can be the same or different. Therefore, the photovoltaic panel 20 can be arranged horizontally or tilted.

[0035] The base 11 is the supporting foundation of the photovoltaic awning 100, and the base 11 can be made of strong and durable materials, such as wood, metal or high-strength plastic. The shape of the base 11 can be rectangular, square or circular, etc. The base 11 can be used for people to walk around or place items. The base 11 can be connected to the ground or the foundation of the building to ensure the stability of the photovoltaic awning 100 in the face of extreme weather such as strong winds. The support column 12 is a structure installed on the base 11, which plays the role of bearing and transferring loads, and can be made of high-strength materials, such as metals, alloys, etc., to ensure the stability of the entire structure.

[0036] The upper surface 21 of the base 11 refers to the surface of the base 11 facing the photovoltaic panel 20. The first positioning structure 110 can be integrally formed with other parts of the base 11; or it can be separately formed with other parts of the base 11 and connected by bolt connection, welding, etc. The number of the first positioning structures 110 can be two, three, four or even more.

[0037] The first positioning structure 110 and the second positioning structure 120 can be positioned by matching the shaft hole. For example, the first positioning structure 110 can be a plurality of flanges, and the shape of the flanges can be a regular shape, such as a column, a cone, or an irregular shape. The second positioning structure 120 can be a plurality of grooves arranged one by one on the support column 12. During installation, the plurality of flanges can be inserted into the plurality of grooves to achieve the matching of the first positioning structure 110 and the second positioning structure 120. Among them, the first positioning structure 110 can also be a plurality of grooves, and the second positioning structure 120 can also be a plurality of flanges.

[0038] The first positioning structure 110 and the second positioning structure 120 can also be positioned by means of a slider and a slide rail. For example, the first positioning structure 110 is a plurality of slide rails installed on the upper surface 21 of the base 11, and the second positioning structure 120 can be a plurality of sliders formed on the support column 12. During installation, the slider can be moved to a predetermined position on the slide rail. After the slide rail moves to the predetermined position, the slider can be fixed by means of a positioning pin, a stopper or a limit screw, etc., which can quickly adjust the orientation of the support column 12 relative to the base 11 and achieve precise positioning.

[0039] The photovoltaic panel 20 is used to convert solar energy into electrical energy. The photovoltaic panel 20 can be different types of solar energy conversion devices such as monocrystalline silicon, polycrystalline silicon or thin-film solar cells, and photovoltaic panels 20 of different efficiencies and sizes can be selected as needed. The photovoltaic panel 20 can be set on the support column 12 in a slot connection manner. For example, the edge of the photovoltaic panel 20 can be directly inserted into the corresponding slot on the support column 12 and fixed by a spring clip, a pressure block or a hand tightening screw. Of course, according to actual needs, the photovoltaic panel 20 can also be set on the support column 12 by other connection methods such as threaded connection and clamp connection.

[0040] See also Figure 2 and Figure 3 In some embodiments, the first positioning structure 110 includes a positioning column 1100, and a plurality of positioning columns 1100 are arranged at intervals along the circumference of the support column 12. The second positioning structure 120 is provided with a positioning hole 1200 that cooperates with the positioning column 1100. The positioning hole 1200 extends from the end face 121 of the support column 12 along the axial direction of the support column 12 toward the interior of the support column 12, and the positioning column 1100 is inserted into the positioning hole 1200.

[0041] In this way, by designing the first positioning structure 110 as a positioning column 1100, and the second positioning structure 120 is provided with a positioning hole 1200 that cooperates with the positioning column 1100, a precise matching relationship between the support column 12 and the base 11 is achieved. The matching of the positioning column 1100 and the positioning hole 1200 reduces the uncertainty and error during installation, so that the support column 12 can be accurately installed at the predetermined position of the base 11. The positioning columns 1100 are arranged at intervals along the circumference of the support column 12, which increases the contact points between the support column 12 and the base 11, which not only improves the positioning accuracy, but also enhances the structural stability of the entire photovoltaic awning 100.

[0042] Specifically, the positioning column 1100 is a columnar structure arranged on the base 11 for cooperating with the support column 12. The positioning column 1100 may be a cylinder, a prism, or the like. The shape of the positioning hole 1200 may be circular, square, or any shape that matches the positioning column 1100. The aperture of the positioning hole 1200 may be equal to the outer diameter of the positioning column 1100. The distance between two adjacent positioning columns 1100 may be equal or unequal. The length, width, and other dimensions of the positioning column 1100 may be equal or unequal. The end face 121 of the support column 12 may be a surface parallel to the upper surface 21 of the base 11, or may be an inclined surface. The positioning hole 1200 may be a blind hole opened on the support column 12, and the depth, aperture, and other dimensions of each positioning hole 1200 may be the same or different.

[0043] In one embodiment, the cross-section of the support column 12 is square, the number of the positioning columns 1100 can be four, the length and width of the four positioning columns 1100 can be equal, the distance between two adjacent positioning columns 1100 can be equal, the positioning holes 1200 are distributed at the four corners of the support column 12, and the four positioning columns 1100 are inserted into the four positioning holes 1200.

[0044] See also Figure 2 In some embodiments, the base 11 is in a sheet shape, and the positioning column 1100 is disposed at a corner 111 of the base 11 .

[0045] It can be understood that the base 11 is generally used for people to walk or place items. By setting a positioning column 1100 at the corner 111 of the base 11, space utilization can be optimized, ensuring that the installation position of the support column 12 is reasonable, and reducing the adverse effects of the support column 12 and the positioning column 1100 on the functional use of the awning.

[0046] Specifically, the sheet-like base 11 refers to a platform structure with a certain area and thickness, and may be rectangular, square, etc. The corner 111 of the base 11 refers to an area where different side edges of the base 11 intersect.

[0047] See also Figure 2 and Figure 3 In some embodiments, a plurality of positioning columns 1100 are arranged equidistantly along the circumference of the support column 12 .

[0048] Thus, the design of equidistant arrangement allows multiple possible installation points to be selected around the support column 12, thereby improving the convenience of installation. In addition, the multiple positioning columns 1100 are equidistantly arranged along the circumference of the support column 12, which means that the force applied by the support column 12 and the photovoltaic panel 20 will be more evenly distributed on the base 11, which helps to improve the stability and load-bearing capacity of the overall structure of the photovoltaic awning 100.

[0049] See also Figure 2 and Figure 3 In some embodiments, a mounting column 112 is disposed on the base 11 , and the mounting column 112 is spaced apart from the positioning column 1100 . A mounting hole 122 is disposed at the center of the end surface 121 of the support column 12 , and the mounting column 112 is inserted into the mounting hole 122 .

[0050] In this way, the use of the mounting column 112 and the positioning column 1100 in cooperation provides a dual fixing mechanism, and the cooperation between the mounting column 112 and the mounting hole 122 helps to reduce the error in the installation process, thereby improving the positioning accuracy, so that the support column 12 can be accurately installed at the predetermined position on the base 11. In addition, the mounting column 112 inserted into the mounting hole 122 at the center of the end surface 121 of the support column 12 provides an additional fixing point for the support column 12, making the connection between the support column 12 and the base 11 more stable.

[0051] Specifically, the mounting column 112 is a columnar structure provided on the base 11 for cooperating with the support column 12, and the mounting column 112 may be a cylinder, a prism, etc. The shape of the mounting hole 122 may be circular, square, or other shapes suitable for the mounting column 112. The diameter of the mounting hole 122 may be equal to the outer diameter of the mounting column 112. The shape and size of the mounting column 112 and the positioning column 1100 may be the same or different.

[0052] In one embodiment, the cross-section of the support column 12 can be a square, the geometric center of the square can be located on the central axis of the mounting hole 122, the positioning column 1100 and the mounting column 112 can both be cylinders, the number of the positioning columns 1100 can be four, the positioning columns 1100 can be arranged at the four corners of the square, the mounting column 112 can be spaced apart from each positioning column 1100, and the distance between the mounting column 112 and each positioning column 1100 can be equal.

[0053] See also Figure 2 In some embodiments, the diameter D1 of the mounting post 112 is greater than the diameter D2 of the positioning post 1100 .

[0054] It can be understood that a larger diameter means that the mounting column 112 has a larger cross-sectional area, which can provide stronger support and better bending resistance. This helps to improve the structural stability of the connection between the support column 12 and the base 11, and reduce displacement or deformation caused by wind or other external forces. In addition, there may be slight errors in the process of the positioning column 1100 matching with the positioning hole 1200. The larger diameter of the mounting column 112 can reduce the adverse effects of these errors on the positioning accuracy.

[0055] See also Figure 1 In some embodiments, the bracket 10 further includes a frame 13 disposed at the other end of the support column 12 , and the photovoltaic panel 20 is mounted on the frame 13 .

[0056] In this way, the support column 12 and the frame 13 can provide a stable structural foundation for the photovoltaic panel 20, so that the photovoltaic panel 20 can be stably placed. In addition, the frame 13 structure is usually more stable than a single support point, so the photovoltaic panel 20 installed on the frame 13 can improve its overall stability and reduce vibration or displacement caused by wind or other external forces. In addition, the frame 13 can be customized according to the size and shape of the photovoltaic panel 20 to accommodate photovoltaic panels 20 of different models and specifications.

[0057] Specifically, the frame 13 is a structure at one end of the support column 12, which is used to fix and support the photovoltaic panel 20. The frame 13 can be made of materials with high strength and good durability, such as aluminum alloy and steel. The frame 13 is fixed to the end of the support column 12 that is different from the base 11, and the frame 13 and the support column 12 can be connected by mechanical connectors or welding. The frame 13 may include supporting components of cross beams, longitudinal beams or other shapes to accommodate photovoltaic panels 20 of different sizes. The photovoltaic panel 20 can be installed on the frame 13 by means of slot connection, bolt connection, adhesion, etc., and can also be fixed to the frame 13 by components such as clamps.

[0058] See also Figure 1 and Figure 3 In some embodiments, there are multiple support columns 12 , and the multiple support columns 12 are arranged at intervals. Each support column 12 is provided with a second positioning structure 120 , and the support column 12 is arranged at a corner 130 of the frame 13 .

[0059] In this way, each support column 12 is provided with a second positioning structure 120, which helps to reduce errors during the installation process, thereby improving positioning accuracy, so that the support column 12 can be accurately installed at a predetermined position on the base 11. In addition, multiple support columns 12 are arranged at intervals and at the corners 130 of the frame 13, so that the force applied by the photovoltaic panel 20 can be more evenly distributed on the support column 12, so that the support column 12 can better bear the weight of the photovoltaic panel 20, and enhance the overall bearing capacity of the support column 12.

[0060] Specifically, the number of the support columns 12 can be two, three, four or even more. For three or more support columns 12, the distance between two adjacent support columns 12 can be equal or unequal. Each support column 12 is provided with a second positioning structure 120 for positioning and fixing. Through the cooperation between the second positioning structure 120 and the first positioning structure 110 on the base 11, each support column 12 can be accurately positioned and fixed on the base 11.

[0061] The corner 130 of the frame 13 refers to the area where the different side edges of the frame 13 intersect. The corner is a key stress point of the frame 13, and the support column 12 is arranged here to improve the stability of the frame 13.

[0062] See also Figure 1 In some embodiments, the photovoltaic awning 100 further includes a sunshade curtain 30 , which is disposed on the frame 13 and located between the two support columns 12 .

[0063] In this way, the sunshade curtain 30 can effectively block the sunlight to adapt to the change of the sun's position, thereby preventing the sunlight from irradiating the interior of the photovoltaic awning 100, and further enhancing the effect of the photovoltaic awning 100 in blocking the sunlight.

[0064] Specifically, the photovoltaic panel 20 is arranged on the frame 13, which means that the top of the photovoltaic awning 100 directly uses the photovoltaic panel 20 as the main part of blocking sunlight, so that the photovoltaic panel 20 can not only play the function of sunshade, but also effectively absorb sunlight to generate electricity, achieving the dual functions of sunshade and energy production. The sunshade curtain 30 further enhances the sunshade effect, especially at the angle that the photovoltaic panel 20 cannot completely block, the position of the sunshade curtain 30 can be adjusted to optimize the sunshade effect, reduce sunlight exposure to the inside of the photovoltaic awning 100, and avoid the problem of failure of the photovoltaic awning 100 to block sunlight. Among them, the inside of the photovoltaic awning 100 refers to the area located below the photovoltaic panel 20 and surrounded by the support column 12 and the frame 13.

[0065] The sunshade 30 is used to provide a shielding function, reduce direct sunlight, lower the temperature of the area below the photovoltaic panel 20, and provide privacy protection or other functions. The sunshade 30 can be made of cloth, plastic or other materials. The sunshade 30 can be arranged on the frame 13 in an adjustable or fixed manner. For example, the sunshade 30 can be fixed to the edge of the sunshade 30 by a hook or other connecting member fixed to the frame 13. For another example, the sunshade 30 can also be automatically retracted and extended by the cooperation of a reel and a driving device. The sunshade 30 can be connected to the reel, and the reel can be rotated under the drive of the driving device, thereby realizing the automatic retraction and extension of the sunshade 30.

[0066] See also Figure 4 and Figure 5 In some embodiments, the photovoltaic awning 100 includes a jet assembly 40 disposed on a bracket 10, the jet assembly 40 includes a nozzle 41 and an air pump 42 connected to the nozzle 41, the air pump 42 is electrically connected to the photovoltaic panel 20, the nozzle 41 is disposed on the bracket 10, and the jet port 410 of the nozzle 41 faces the upper surface 21 of the photovoltaic panel 20.

[0067] In this way, the jet port 410 of the nozzle 41 is directed toward the upper surface 21 of the photovoltaic panel 20, and the contaminated area of ​​the photovoltaic panel 20 can be directly cleaned, thereby improving the cleaning efficiency. At the same time, the nozzle 41 can be used to accurately control the direction of the airflow, ensuring that the airflow directly acts on the upper surface 21 of the photovoltaic panel 20, thereby achieving precise cleaning. In addition, since the air pump 42 is electrically connected to the photovoltaic panel 20, the operation of the air pump 42 can utilize the electrical energy generated by the photovoltaic panel 20 itself, which can reduce the dependence on an external power source.

[0068] Specifically, the jet assembly 40 is a device for removing dust and other contaminants on the photovoltaic panel 20, thereby maintaining the cleanliness and photoelectric conversion efficiency of the photovoltaic panel 20. The jet assembly 40 can be arranged on the bracket 10 by bolt connection, pin connection, etc. The height of the jet assembly 40 can be higher than the height of the photovoltaic panel 20, so as to spray the jet toward the upper surface 21 of the photovoltaic panel 20. The upper surface 21 of the photovoltaic panel 20 refers to the surface of the photovoltaic panel 20 facing the light source, such as the surface facing the sun.

[0069] The nozzle 41 is the output part of the jet assembly 40, and is responsible for ejecting the airflow generated by the air pump 42 in a specific manner. The nozzle 41 usually has one or more jet ports 410, which can adjust the direction and intensity of the airflow. The shape of the jet port 410 can be regular shapes such as round, square, etc., or irregular shapes.

[0070] The air pump 42 is the power source of the jet assembly 40 and is responsible for compressing air to generate airflow. The electric energy generated by the photovoltaic panel 20 is directly supplied to the air pump 42 to drive the air pump 42 to work. The air pump 42 can be directly electrically connected to the photovoltaic panel 20 through a cable, or it can be electrically connected to the photovoltaic panel 20 through an intermediate device such as an inverter and a voltage stabilizer. The air pressure and flow of the air pump 42 can be adjusted according to demand. The air pump 42 can adjust the air pressure and flow to adjust the cleaning intensity according to the severity of dust accumulation on the photovoltaic panel 20.

[0071] The air pump 42 and the nozzle 41 may be arranged in a one-to-one correspondence, or the air pump 42 may correspond to a plurality of nozzles 41. For example, the air pump 42 may include a plurality of airflow channels, and the plurality of airflow channels may be connected to a plurality of nozzles 41 arranged on the bracket 10. The airflow channel of the air pump 42 may be buried in the bracket 10, thereby reducing the adverse effect of the external environment on the airflow channel.
