[0021] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Embodiment 1: like Figures 1 to 4 As shown, the present application provides a flexible photovoltaic angle adjustment device, including a photovoltaic panel 1, a driving member 2, a mounting assembly 3, a first rotating assembly 4 and a second rotating assembly 5.

[0024] By adopting a flexible photovoltaic angle adjustment device, the photovoltaic panel 1 is allowed to be precisely adjusted on multiple axes, thereby realizing automatic adjustment of the angle of the photovoltaic panel 1 according to the dynamic changes in the sun's position to maximize the sunlight receiving efficiency.

[0025] The mounting assembly 3 includes a mounting frame 31 and an articulated frame 32 . The articulated frame 32 includes an articulated end 321 . The mounting frame 31 is hinged on the articulated end 321 . The photovoltaic panel 1 is disposed on the mounting frame 31 .

[0026] The mounting frame 31 and the articulated frame 32 enable the photovoltaic panel 1 to be stably mounted and flexibly rotated on one axis, thereby enhancing the structural stability and operational flexibility of the system.

[0027] The driving member 2 is disposed on one side of the first rotating assembly 4 , and the driving member 2 is connected to the first rotating assembly 4 and the second rotating assembly 5 in sequence.

[0028] By sequentially connecting the driving member 2 with the first rotating assembly 4 and the second rotating assembly 5, a simplified driving system is achieved, thereby controlling two rotation directions through a single driving source, reducing costs and system complexity.

[0029] The first rotating assembly 4 is connected to the articulated frame 32 , and the first rotating assembly 4 is used to drive the articulated frame 32 to rotate along the first output axis of the first rotating assembly 4 .

[0030] Through the operation of the first rotating assembly 4, precise angle adjustment along a main axis is achieved, so that the photovoltaic panel 1 can track the daily rising and setting of the sun.

[0031] The second rotating assembly 5 is arranged on a side of the first rotating assembly 4 away from the driving member 2, and is used to drive the mounting frame 31 to rotate along the second output axis of the hinge end 321; wherein the second output axis is staggered and vertically arranged with the first output axis.

[0032] Through the independent control of the second rotating assembly 5, the rotation adjustment of another axis is achieved, so that the photovoltaic panel 1 can be more accurately aligned with the changes in the height of the sun, further improving the energy capture rate.

[0033] When the first rotating assembly 4 drives the mounting frame 31 to rotate along the first output axis, the second rotating assembly 5 drives the mounting frame 31 to rotate along the second output axis of the hinge end 321 .

[0034] Specifically, when the output end of the driving member 2 rotates forward, the driving member 2 drives the first rotating component 4 and the second rotating component 5 to move. At this time, the photovoltaic panel 1 not only rotates and tilts in the clockwise direction of the first output axis, but also rotates and tilts in the counterclockwise direction of the second output axis; when the output end of the driving member 2 rotates reversely, the driving member 2 drives the first rotating component 4 and the second rotating component 5 to move. At this time, the photovoltaic panel 1 not only rotates and tilts in the counterclockwise direction of the first output axis, but also rotates and tilts in the clockwise direction of the second output axis.

[0035] Furthermore, the driver 2 drives the photovoltaic panel 1 to the initial stage, i.e., early morning, to face the sun, and until the final stage, i.e., after dusk, the driver 2 drives the photovoltaic panel 1 to the initial stage again to prepare for the next day's photoelectric efficiency conversion. In addition, since the earth and the sun are always vertically illuminated except near the equator, there are illumination inclination angles in other geographical locations. Through this coordinated rotation mechanism, it is only necessary to adjust the position of the flexible photovoltaic angle adjustment device according to the longitude and latitude to ensure that the photovoltaic panel 11 can match the illumination inclination angle at any time. After the season changes, the position can be fine-tuned to achieve the optimal angle to face the sun, which greatly improves the system's photoelectric conversion efficiency and energy output.

[0036] In this embodiment, the photovoltaic panel 1 is mounted on the mounting frame 31, and the mounting frame 31 is connected to the hinge end 321 through the hinge frame 32, so that it can rotate on different axes. The driving member 2 is mounted on one side of the first rotating assembly 4 and is responsible for directly driving the first rotating assembly 4. When the driving member 2 is started, it first drives the first rotating assembly 4 to rotate the mounting frame 31 along the first output axis direction. At the same time, the second rotating assembly 5 also drives the mounting frame 31 to rotate along the second output axis direction of the hinge end 321 under the action of the driving member 2. The photovoltaic panel 1 can be accurately adjusted at two different axes at the same time to align with the sun in the best way. The photovoltaic panel 1 is allowed to rotate on two independent axes through the flexible photovoltaic angle adjustment device, which greatly improves the solar energy capture efficiency. Using the same driving member 2 to control the first rotating assembly 4 and the second rotating assembly 5 at the same time not only simplifies the mechanical structure, but also reduces costs and potential maintenance points; and because it can rotate along two different axes, the photovoltaic panel 1 can be adjusted more accurately according to the real-time position of the sun, and can provide maximum energy output at different times of the day, thereby improving the energy efficiency and economic benefits of the entire system. At the same time, the failure rate caused by complex mechanical structure is reduced, the reliability of the system is improved, the overall mechanical structure is simplified, the production and maintenance costs are reduced, and the problems of high cost and mechanical complexity of flexible photovoltaic angle adjustment devices are solved.

[0037] Embodiment 2: like Figures 1 to 4As shown, the mounting assembly 3 also includes a first mounting block 33 and a second mounting block 34. The first rotating assembly 4 is arranged on the first mounting block 33. The first rotating assembly 4 includes a connecting block 41, a transmission wheel 42 and a reduction wheel 43. The transmission wheel 42 is connected to the driving member 2, and the reduction wheel 43 is meshed with the transmission wheel 42. One end of the connecting block 41 is provided with a ring tooth 411, and the ring tooth 411 is meshed with the reduction wheel 43. The end of the connecting block 41 away from the ring tooth 411 is connected to the articulated frame 32. The connecting block 41 is used to drive the articulated frame 32 to rotate along the axial direction of the driving member 2.

[0038] Through the meshing of the transmission wheel 42, the reduction wheel 43 and the ring gear 411, accurate and smooth rotation control of the articulated frame 32 is achieved, thereby ensuring that the photovoltaic panel 1 can be accurately aligned with the sun and improving the energy capture efficiency.

[0039] A transmission shaft 6 is disposed between the transmission wheel 42 and the second rotating assembly 5 , and the transmission shaft 6 is connected to the axis of the transmission wheel 42 .

[0040] The direct connection of the transmission shaft 6 ensures direct transmission of the transmission force and synchronous movement, making the second rotating component 5 more stable and efficient when receiving force.

[0041] like Figures 1 to 4 As shown, the second rotating component 5 is arranged on the second mounting block 34, and the second rotating component 5 includes a mounting sleeve 51, a crank member 52, a telescopic member 53, a hinge member 54 and a connecting member 55. The mounting sleeve 51 is fixed on the second mounting block 34, the crank member 52 is connected to the transmission shaft 6, and the telescopic member 53 and the crank member 52 are hinged in the mounting sleeve 51 to perform linear reciprocating motion.

[0042] Through the linkage design of the crank member 52 and the telescopic member 53, fine linear and rotational motion control is achieved, so that the second rotating component 5 can accurately adjust the position of the photovoltaic panel 1 at different angles.

[0043] One end of the hinged member 54 is connected to the telescopic member 53, and the end of the hinged member 54 away from the telescopic member 53 is hinged to the connecting member 55. The hinged rotation direction of the hinged member 54 and the connecting member 55 is consistent with the rotation direction of the second output axis of the hinged end 321, and the end of the connecting member 55 away from the hinged member 54 is hinged to the mounting frame 31.

[0044] One end of the hinge 54 is connected to the telescopic member 53 so that the hinge 54 can follow the telescopic member 53 to make a linear reciprocating motion. At the same time, the hinge 54 is hinged to the connecting member 55, and the connecting member 55 is hinged to the mounting frame 31, that is, the hinge 54, the connecting member 55 and the mounting frame 31 form two hinged structures that rotate axially at right angles to each other, thereby realizing multi-directional adjustment, further increasing the adaptability of the device to environmental changes to cope with multi-angle changes in sunlight.

[0045] The mounting frame 31 includes a connecting portion 311 , and the connecting member 55 is hinged to the connecting portion 311 , wherein the direction in which the connecting member 55 is hinged to the connecting portion 311 is consistent with the axial direction of the driving member 2 .

[0046] Through the hinged design of the connecting member 55 and the connecting part 311, it is ensured that when the driving member 2 drives the connecting block 41 to drive the articulated frame 32 to rotate, the second rotating component 5 will not interfere with it, so that the entire mounting frame 31 can rotate synchronously along the axial direction of the driving member 2, thereby enhancing the mechanical synchronization and operating efficiency of the entire system.

[0047] like Figures 1 to 4 As shown, a relief opening 331 is provided on the first mounting block 33 , the driving member 2 is fixed on the mounting block, and a driving terminal of the driving member 2 passes through the relief opening 331 and is connected to the transmission wheel 42 .

[0048] Through the design of the avoidance opening 331, a tight and flexible connection between the driving member 2 and the transmission assembly is achieved, the assembly layout is optimized, and the space occupation and potential mechanical interference are reduced.

[0049] A bearing plate 511, a first clamping plate 512 and a second clamping plate 513 are arranged on the outer peripheral wall of the mounting sleeve 51, the bearing plate 511 is welded to the outer peripheral wall of the mounting sleeve 51, the first clamping plate 512 and the second clamping plate 513 are welded to the bearing plate 511, and the first clamping plate 512 is provided with a countersunk hole 5121, and the second mounting block 34 is provided with a threaded hole 341 aligned with the countersunk hole 5121, and the countersunk hole 5121 is provided with a bolt that penetrates the countersunk hole 5121 and the threaded hole 341 in sequence.

[0050] By using the bearing plate 511, the first clamping plate 512 and the second clamping plate 513, the fixation and stability between the mounting sleeve 51 and the second mounting block 34 are enhanced, and the mechanical strength and durability of the second rotating assembly 5 during operation are ensured. The first clamping plate 512 is bolted to the second mounting block 34 through the countersunk hole 5121 and the threaded hole 341 and the bolts, which provides additional mechanical stability and reliability, and ensures the safety and durability of the assembly in long-term operation.

[0051] The mounting assembly 3 further includes a support frame 35 , and the first mounting block 33 and the second mounting block 34 are fixed on the support frame 35 .

[0052] The structure of the support frame 35 enhances the bearing capacity and structural stability of the overall device, providing a solid foundation for the stable operation of the system.

[0053] The driving component 2 is any one of the following: a servo motor and a stepping motor.

[0054] By selecting a servo motor or a stepper motor as the driving element 2, a high-precision and controllable driving output is achieved, meeting the system's requirements for precise angle adjustment.

[0055] In this embodiment, high-precision and dynamic adjustment of the photovoltaic panel 1 in multiple axes is achieved, so that the photovoltaic panel 1 can be efficiently aligned with the sun and maximize sunlight capture, thereby improving the energy efficiency and output performance of the entire system; in addition, the maintenance requirements are reduced, the reliability and service life of the device are improved, and a photovoltaic angle adjustment device with stable structure, flexible response and high efficiency is provided.
