[0033] See also Figure 1 The sunshade 100 of the embodiment of the utility model includes a bracket 10, a plurality of photovoltaic panels 20 and a driving device 30. The plurality of photovoltaic panels 20 are in the shape of long sheets, and the plurality of photovoltaic panels 20 are arranged on the bracket 10 along the width direction W of the photovoltaic panels 20; the driving device 30 is arranged on the bracket 10 and connected to the photovoltaic panels 20, and the driving device 30 is used to drive the photovoltaic panels 20 to rotate around a rotation axis, and the rotation axis is parallel to the length direction L or the width direction W of the photovoltaic panels 20.

[0034] In the sunshade 100 of the embodiment of the utility model, the driving device 30 can drive the photovoltaic panel 20 to rotate around the rotation axis, so that the inclination angle of the photovoltaic panel 20 can be adjusted according to the position change of the sun in different time periods to maximize the reception of solar radiation, thereby improving the photovoltaic conversion efficiency. In addition, since the photovoltaic panel 20 can rotate, the sunshade 100 can also provide lighting and ventilation functions in some application scenarios.

[0035] Specifically, the 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 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.

[0036] The bracket 10 is a structure for supporting and fixing the photovoltaic panel 20, providing a mounting base for the photovoltaic panel 20, so that the photovoltaic panel 20 can operate stably. The bracket 10 can be made of metal or other high-strength materials, and the bracket 10 can be used to support the photovoltaic panel 20 and keep it in a fixed position. The number of brackets 10 can be multiple, 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.

[0037] The photovoltaic panel 20 is used to convert solar energy into electrical energy. The electrical energy converted by the photovoltaic panel 20 can be used by the driving device 30. 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 top of the bracket 10 in a slot connection manner. For example, the edge of the photovoltaic panel 20 can be directly inserted into the corresponding slot on the bracket 10 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 bracket 10 by other connection methods such as threaded connection and clamp connection. The number of photovoltaic panels 20 can be two, three, four or even more, and the width direction W of each photovoltaic panel 20 can be the same.

[0038] The driving device 30 can be connected to the photovoltaic panel 20 by mechanical or electric means to drive the photovoltaic panel 20 to rotate around the rotation axis. The driving method of the driving device 30 can be various forms such as motor 31 drive, hydraulic drive or pneumatic drive. The driving device 30 can be used to adjust the angle of the photovoltaic panel 20 to adapt to changes in the position of the sun. When the sunlight conditions change, such as the sun rises, moves or sets, the driving device 30 drives the photovoltaic panel 20 to rotate around the rotation axis according to a preset program or real-time monitoring data to maintain the optimal incident angle between the photovoltaic panel 20 and the sunlight. Among them, the real-time monitoring data can be achieved through observation equipment such as a sun angle sensor.

[0039] The rotation axis is the center line of the photovoltaic panel 20, and the rotation axis is parallel to the length direction L or width direction W of the photovoltaic panel 20. For a long sheet photovoltaic panel 20, the photovoltaic panel 20 can rotate around the symmetry axis of the two long sides or the symmetry axis of the two wide sides, and the symmetry axis is the rotation axis.

[0040] See also Figure 1 In some embodiments, the rotation axis is parallel to the length direction L of the photovoltaic panel 20 , and there are multiple driving devices 30 , with one driving device 30 connected to a corresponding photovoltaic panel 20 .

[0041] In this way, each photovoltaic panel 20 is equipped with an independent driving device 30 , and each photovoltaic panel 20 can be adjusted independently, which can reduce the chain reaction caused by the failure of one driving device 30 , thereby improving the overall reliability and stability of the driving device 30 .

[0042] Specifically, the number of the driving devices 30 can be two, three, four or even more. The driving device 30 can be connected to the photovoltaic panel 20 closest to itself, thereby shortening the transmission distance, improving the transmission efficiency, and reducing the use of connectors and reducing costs. When driving the photovoltaic panel 20, the driving device 30 can drive all photovoltaic panels 20 to rotate at the same time, or it can drive multiple photovoltaic panels 20 to rotate one after another.

[0043] See also Figure 1 and Figure 2 In some embodiments, the driving device 30 includes a motor 31, a driving shaft 32 and a gear assembly 33. The motor 31 is disposed on the bracket 10 and is electrically connected to the photovoltaic panel 20. The driving shaft 32 is fixedly connected to the photovoltaic panel 20. The gear assembly 33 connects the driving shaft 32 and the motor 31.

[0044] In this way, through the precise control of the motor 31, the rotation of the photovoltaic panel 20 can be ensured to be more precise and stable, and the accuracy of solar tracking can be improved, thereby maximizing the energy conversion efficiency of the photovoltaic panel 20. Since the motor 31 is electrically connected to the photovoltaic panel 20, the motor 31 can directly use the electric energy generated by the photovoltaic panel 20 to operate, which can reduce the dependence of the driving device 30 on the external power supply.

[0045] In addition, the use of the gear assembly 33 can effectively convert the rotational motion of the motor 31 into the rotational motion required by the photovoltaic panel 20, and the gear assembly 33 helps to reduce the volume of the entire drive device 30. In addition, the gear assembly 33 and the motor 31 cooperate to drive in a simple structure and low cost.

[0046] Specifically, the motor 31 is the power source of the driving device 30, which is responsible for converting electrical energy into mechanical energy to drive the rotation of the driving shaft 32. The motor 31 can be a DC motor 31, an AC motor 31, a servo motor 31 or a stepper motor 31, etc., and the specific type can be selected according to actual needs. The motor 31 can be mounted on the bracket 10 by mechanical fixing, such as bolt fixing, welding or clamping. The photovoltaic panel 20 can be used to provide electrical energy to the motor 31, and the electrical connection between the motor 31 and the photovoltaic panel 20 can be achieved by means of wires or cables, and the cable is connected from the input end of the motor 31 to the output end of the photovoltaic panel 20. A battery or a transformer circuit can be provided between the motor 31 and the photovoltaic panel 20.

[0047] The gear assembly 33 can be connected to the motor 31 and the drive shaft 32 by key connection, spline connection or direct meshing. The gear assembly 33 is used to convert the rotation speed and torque of the motor 31 into parameters suitable for the drive shaft 32. The drive shaft 32 can be fixedly connected to the photovoltaic panel 20 by welding, bolt connection, etc., so that the photovoltaic panel 20 can rotate with the drive shaft 32.

[0048] See also Figure 2 In some embodiments, the gear assembly 33 includes a plurality of gears, the plurality of gears are meshed with each other, and a speed ratio of the plurality of gears is greater than 1.

[0049] In this way, the gear transmission is more stable than the direct transmission of the motor 31, so the photovoltaic panel 20 can rotate stably. At the same time, since the speed ratio of the multiple gears is greater than 1, the gear assembly 33 can reduce the speed output by the motor 31, so that the photovoltaic panel 20 can be adjusted in smaller angle increments, which is easy to control.

[0050] Specifically, the number of gears can be two, three, four or even more, and the meshing of the gears can be the meshing of parallel axis gears (such as spur gears and helical gears), intersecting axis gears (such as bevel gears and spiral gears) and staggered axis gears (such as worms and worm wheels). The gears can have a cross-meshing or multi-layer meshing relationship.

[0051] The speed ratio can reflect the relationship between the speed of the motor 31 and the output speed of the drive shaft 32. When the speed ratio is greater than 1, it indicates that the speed of the motor 31 is higher than the output speed of the drive shaft 32. This means that the gear assembly 33 reduces the output speed and increases the output torque while transmitting the torque.

[0052] See also Figure 1 In some embodiments, the bracket 10 includes a support column 11 and a frame 12 disposed at one end of the support column 11 , the photovoltaic panel 20 is mounted on the frame 12 , and the driving device 30 is disposed on the frame 12 .

[0053] Thus, the bracket 10 is composed of a support column 11 and a frame 12 disposed at one end of the support column 11. This structure provides better stability and support force, which is conducive to bearing the weight of the photovoltaic panel 20 and the dynamic load of the driving device 30. At the same time, since both the photovoltaic panel 20 and the driving device 30 are disposed on the frame 12, it helps to make the awning 100 compact and reduce the occupied space.

[0054] Specifically, the support column 11 is a part of the bracket 10, 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. The frame 12 is a structure at one end of the support column 11, which is used to fix and support the photovoltaic panel 20. The frame 12 may include a crossbeam, a longitudinal beam, or other supporting components of a shape to accommodate photovoltaic panels 20 of different sizes.

[0055] The photovoltaic panel 20 can be arranged on the frame 12 by means of slot connection, bolt connection, adhesion, etc., or can be fixed to the frame 12 by means of a clamp or other components. The driving device 30 can be arranged on the frame 12 by means of slot connection, bolt connection, etc., or can be fixed to the frame 12 by means of a clamp or other components. The photovoltaic panel 20 and the driving device 30 are spaced apart to reduce the possibility of interference. At the same time, the driving device 30 should be arranged close to the photovoltaic panel 20 to shorten the transmission distance and improve the transmission efficiency.

[0056] In some embodiments, the photovoltaic panel 20 is capable of rotating between a horizontal state and an inclined state, and the rotating angle of the photovoltaic panel 20 from the horizontal state to the inclined state is less than 90 degrees.

[0057] In this way, since the photovoltaic panel 20 can rotate between a horizontal state and an inclined state, the photovoltaic panel 20 can adjust the tilt angle according to the position of the sun to maximize the reception of solar radiation. Limiting the rotation angle of the photovoltaic panel 20 to less than 90 degrees can reduce the mechanical stress of the drive device 30, thereby reducing wear and tear and extending the service life of the drive device 30.

[0058] Specifically, the horizontal state refers to a state parallel to the ground, and the inclined state refers to a state forming a certain angle with the ground. The photovoltaic panel 20 can rotate from the horizontal state to the inclined state at an angle of 5°, 15°, 30°, 45°, 60°, 75°, etc.

[0059] See also Figure 3 and Figure 4 In some embodiments, when the photovoltaic panel 20 is in a tilted state, two adjacent photovoltaic panels 20 partially overlap along the thickness direction D of the photovoltaic panel 20 .

[0060] In this way, when the photovoltaic panels 20 are in an inclined state, adjacent photovoltaic panels 20 partially overlap in the thickness direction, so the photovoltaic panels 20 as a whole occupy less space, which can improve the space utilization efficiency of the entire awning 100. In addition, this can effectively reduce the probability of rainwater passing directly through the photovoltaic panels 20, thereby reducing the impact of rainwater on the space environment below the photovoltaic panels 20.

[0061] Specifically, partial overlap means that the orthographic projections of two adjacent photovoltaic panels 20 in the thickness direction partially overlap each other, but not completely. Depending on the different rotation directions of the photovoltaic panels 20, the overlapping state of the two adjacent photovoltaic panels 20 may be different. For example, when the photovoltaic panel rotates counterclockwise, the overlapping state of the two adjacent photovoltaic panels 20 may be as follows: Figure 3 For another example, when the photovoltaic panel rotates clockwise, the overlapping state of two adjacent photovoltaic panels 20 is as shown in FIG. Figure 4 Of course, Figure 3 and Figure 4 This is only an illustration. For different driving modes, two adjacent photovoltaic panels 20 may present other states.

[0062] See also Figure 5 In some embodiments, the photovoltaic panel 20 can rotate between a horizontal state and an inclined state. When the photovoltaic panel 20 is in the inclined state, there is a gap 101 between two adjacent photovoltaic panels 20. The awning 100 also includes a flexible seal 40 connected to the photovoltaic panel 20, and the flexible seal 40 seals the gap 101.

[0063] In this way, the use of the flexible seal 40 can effectively seal the gap 101 between adjacent photovoltaic panels 20, reduce the probability of rainwater dripping through the gap 101 to the area below when the photovoltaic panel 20 is tilted, and thus reduce the impact of rainwater on the space environment below the photovoltaic panel 20. In addition, the flexible seal 40 can act as a buffer medium to reduce the contact and interference between adjacent photovoltaic panels 20 that may occur under rotation or wind load, thereby reducing the wear of the photovoltaic panel 20 and increasing the service life of the photovoltaic panel 20.

[0064] Specifically, the flexible seal 40 can be made of a flexible material, such as rubber, silicone, plastic, etc., and is used to fill or cover the gap 101 between two adjacent photovoltaic panels 20. The flexible seal 40 can have good elasticity and durability. When the photovoltaic panel 20 is in a horizontal state, the flexible seal 40 can be in a compressed state. At this time, the flexible seals 40 on the two adjacent photovoltaic panels 20 squeeze each other. When the photovoltaic panel 20 changes from a horizontal state to an inclined state, the flexible seals 40 on the two adjacent photovoltaic panels 20 are deformed and can still maintain contact. When the photovoltaic panel 20 changes from an inclined state to a horizontal state again, the flexible seals 40 on the two adjacent photovoltaic panels 20 return to a mutually squeezed state.

[0065] The flexible seal 40 can prevent rain, dust or other foreign matter from passing through, and can also reduce the vibration and noise generated when wind passes through the gap 101. The flexible seal 40 can be connected to the photovoltaic panel 20 by gluing, clamping, etc., so that the flexible seal 40 will not fall off when the photovoltaic panel 20 rotates or is subjected to external force.

[0066] See also Figure 1 In some embodiments, the awning 100 further includes a base 50 , and the bracket 10 is connected to the base 50 .

[0067] In this way, the base 50 provides a more stable foundation for the entire awning 100, making the bracket 10 and the photovoltaic panel 20 arranged on the bracket 10 more stable, thereby enhancing the stability of the overall structure of the awning 100.

[0068] Specifically, the base 50 is the supporting foundation of the photovoltaic awning 100, and the base 50 can be made of strong and durable materials, such as wood, metal or high-strength plastic. The base 50 can be used for people to walk around or place items. The base 50 can be fixed to the bottom of the bracket 10 by bolts, screws or welding, or it can be fixed to the base 50 by plug-in connection. For example, the bottom of the bracket 10 is designed with a slot or tubular structure for inserting the base 50, which is locked by a pin or a buckle. The base 50 can be provided with a mounting hole, which can be used to connect to the bottom of the bracket 10. At the connection between the bracket 10 and the base 50, a gasket or a sealing ring can be set to improve stability and wind and rainproof performance.

[0069] See also Figure 1 and Figure 6 In some embodiments, the awning 100 also includes an energy storage battery 60 , which is electrically connected to the photovoltaic panel 20 , and the energy storage battery 60 is disposed in the base 50 .

[0070] In this way, the design of the integrated energy storage battery 60 simplifies the installation process, because there is no need to separately place the energy storage battery 60 outside the awning 100, thereby reducing the number of installation points and wiring, making maintenance work more convenient, and avoiding external messy lines and equipment, thereby improving the overall aesthetics of the awning 100. In addition, the design of the built-in energy storage battery 60 reduces the impact of external factors on the energy storage battery 60, such as weather changes or accidental impacts, thereby improving the safety of the entire energy storage battery 60.

[0071] Specifically, the energy storage battery 60 can be a lithium-ion battery, a lead-acid battery, or other types of rechargeable batteries. The energy storage battery 60 is used to store the electrical energy generated by the photovoltaic panel 20, and can power loads such as household appliances and portable devices. The energy storage battery 60 and the photovoltaic panel 20 can be directly connected by a cable, or they can be electrically connected through intermediate devices such as a junction box or a busbar. The energy storage battery 60 can be connected to the inner surface of the base 50 by gluing, threading, etc. Among them, the gluing method can prevent shock and reduce mechanical wear. The base 50 can be provided with a battery tray or a fixing frame to facilitate the installation or removal of the energy storage battery 60.
