Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a supporting structure of a photovoltaic module. Background Art

[0002] Currently, most photovoltaic panel support structures are fixed and cannot be adjusted in angle to follow the movement of the sun, resulting in panels failing to maximize their power generation efficiency. While some support structures, such as tracking systems, are adjustable and can automatically adjust their angle to follow the movement of the sun, these systems typically rely on motors and sensors, inevitably consuming a certain amount of electricity. This additional power consumption offsets the power generation gains achieved through optimized angles, especially in smaller-scale photovoltaic systems.

[0007] In any of the above technical solutions, the first supporting part also includes: a first shell, connected to the base through an elastic component; a first rod body, sleeved inside the first shell, and the inner wall of the first shell, the outer wall of the first rod body and the supporting end form the first inner cavity; wherein the supporting end is located between the first shell and the first rod body, and the first shell supports the supporting end through the driving medium of the first inner cavity.

[0008] In any of the above technical solutions, the elastic component includes: a support plate; a groove is provided on the upper surface of the base, and one end of the support plate is slidably installed on the inner wall of the groove; the other end of the support plate is rotatably connected to the lower surface of the first shell; a spring is arranged inside the groove; one end of the spring is fixedly connected to the inner wall of the groove, and the other end of the spring is connected to the support plate; the length of the spring is used to adjust the height of the support end relative to the base.

[0009] In any of the above technical solutions, at least two grooves are configured along the circumference of the first rod body; the spring is in a compressed state inside the groove, so that when the driving medium drives the support end to move longitudinally, it applies a force to the first shell through the support plate.

[0010] In any of the above technical solutions, the support end includes: a second shell, whose inner wall is formed with a third inner cavity; the first rod body is sleeved inside the second shell through the third inner cavity, and the top of the second shell is hinged to the lower part of the assembly seat; an extended edge is circumferentially arranged on the bottom outer edge of the second shell; the extended edge is used to divide the first inner cavity and block the driving medium, and the first inner cavity located below the extended edge is filled with the driving medium.

[0011] In any of the above technical solutions, the driving part and the pipe are both made of translucent material; the part of the pipe close to the first shell is spirally wrapped around the first rod body; along the swing direction of the assembly seat, a light shielding plate is installed on the base for circumferentially shielding the pipe.

[0012] In any of the above technical solutions, the assembly seat includes a first seat body connected to the support end and a second seat body for assembling the photovoltaic module; and the first seat body and the second seat body are connected by a second support part, and a fourth inner cavity connected to the second inner cavity is formed inside the second support part, so that the second seat body can swing circumferentially relative to the first seat body.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] By introducing the support end and the assembly seat which can be dynamically adjusted, the photovoltaic module can automatically adjust its angle according to the position of the sun, solving the problem that the fixed support structure cannot adjust the angle with the movement of the sun, limiting the power generation efficiency of the photovoltaic panel. By dynamically adjusting the angle of the photovoltaic panel to maximize the capture of sunlight, the power generation efficiency of the photovoltaic panel is significantly improved.

[0018] The driving medium naturally expands or shrinks under the action of heat, without the need for external energy input, thereby more efficiently utilizing solar energy. Since natural thermal expansion and contraction are relied on as a power source, rather than electric motors or other electromechanical devices, energy consumption is reduced during operation. The problem that traditional adjustable designs such as electric tracking systems can track the sun but consume additional electricity, offsetting part of the power generation gain, is solved.

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0029] Please refer to Figures 1-4 , the following describes a support structure of a photovoltaic module according to some embodiments of the present application.

[0030] Embodiments of the first aspect of the present application propose a support structure of a photovoltaic module. In some embodiments of the present application, as shown in Figures 1-4 , the support structure of the photovoltaic module comprises:

[0031] A base 1 is provided with a plurality of first support parts 2 in the circumferential direction, each first support part 2 is used to adapt to the direction of swing required, so that the photovoltaic module can better adapt to the emission direction of sunlight, and optimize the conversion efficiency reduction of the solar panel caused by light reflection and other losses. A first inner cavity is formed in the first support part 2; the first support part 2 comprises a support end, at least part of the support end is located in the first inner cavity and can move longitudinally in the first inner cavity to adapt to the requirement of angle adjustment.

[0032] The assembly seat 3 is connected to the support end at the lower part, and the angle of the assembly seat 3 relative to the sunlight is adjusted under the movement of multiple support ends; the upper part of the assembly seat 3 is used to assemble the photovoltaic module, and the upper part of the assembly seat 3 other than the photovoltaic module is circumferentially installed with multiple driving parts 4; a second inner cavity is formed inside the driving part 4, and the second inner cavity and the first inner cavity are connected by a pipe 5; the first inner cavity and the second inner cavity are filled with a driving medium 6, and the driving medium 6 is transported in boxes through the pipe 5; the driving medium 6 is specifically a liquid that can expand after being exposed to sunlight, so that the pressure of the liquid inside the multiple driving parts 4 is different due to different degrees of sunlight exposure, and the different pressures make the support ends at different heights, and the assembly seat 3 produces different swing angles.

[0033] The photovoltaic module protrudes upward from the driving part 4 along its preset light-receiving direction; when the propagation direction of sunlight toward the photovoltaic module forms an angle with the light-receiving direction, the photovoltaic module exposes or blocks at least part of each driving part 4, so that when the sunlight deviates from the ideal light-receiving direction of the photovoltaic module, the photovoltaic module blocks part of the driving part 4 and generates different degrees of heating of the driving medium 6, thereby realizing the swing of the driving assembly seat 3 and adapting to the direction of the sunlight, causing the driving medium 6 to expand or contract in each first inner cavity, and driving the support end to drive the assembly seat 3 to swing, so as to reduce the angle as the propagation direction continues to change.

[0034] The present invention provides a support structure for a photovoltaic module, in which a base 1 serves as the foundation of the entire support structure, and its structure supports a plurality of movable first support parts 2. These first support parts 2 are arranged along the circumference of the base 1, so that the photovoltaic module can adjust its angle accordingly according to the position of the sun. This design allows the photovoltaic module to automatically or semi-automatically adjust its angle facing the sun at different times of the day, thereby maximizing the reception of light; the first support part 2 is a key component that allows the photovoltaic panel to swing. A first inner cavity is formed inside each support part, and at least a portion of the support end is located in this first inner cavity. With this configuration, the support end can move longitudinally within the inner cavity, thereby achieving precise adjustment of the angle of the photovoltaic panel.

[0035] When the sun's position changes, a passive mechanical trigger senses changes in light intensity or direction. This sensing triggers the first support portion 2, driving the support end to move within the first inner cavity, changing the tilt angle of the photovoltaic panel. By dynamically adjusting the angle of the photovoltaic panel, light reflection losses can be reduced and the photovoltaic panel can receive sunlight at the optimal angle for most of the day, significantly improving the efficiency of solar energy conversion. The design may also include elastic materials or buffering devices to cushion impacts caused by wind or other external forces, ensuring structural stability and the safety of the photovoltaic panel.

[0036] The assembly base 3 is one of the core components of the entire support structure, and its lower part is connected to the support end. The design of the assembly base 3 enables it to adjust the angle of the photovoltaic module relative to the sunlight under the movement of the support end, thereby maximizing the efficiency of light energy capture; a plurality of drive parts 4 are installed circumferentially on the upper part of the assembly base 3, and each of these drive parts 4 has a second inner cavity formed therein. These second inner cavities are connected to the first inner cavity of the first support part 2 through a pipe 5, forming a closed fluid movement channel; the first inner cavity and the second inner cavity are filled with a drive medium 6, which can expand under sunlight. The medium is usually a liquid with a high thermal expansion coefficient, such as certain types of oil or other thermal expansion materials.

[0037] When sunlight shines directly on the photovoltaic module, it also strikes the driver 4. The liquid within the driver 4 expands due to heat, causing pressure changes. Because the level of sunlight exposure varies throughout the day, the liquid's expansion also changes, resulting in a difference in pressure between the second inner chamber and the first inner chamber. This pressure difference causes the liquid to flow through the inner chamber via pipe 5, affecting the height of the support end. As the liquid flows through the inner chamber, the support end rises or falls, adjusting the position and tilt angle of the assembly base 3. This adaptive adjustment ensures that the photovoltaic module always maintains an optimal angle to the sun for maximum energy absorption and conversion efficiency. This solution utilizes solar energy itself as the driving force, rather than relying on electric motors or electronic sensors, thus saving energy and reducing maintenance costs. It can quickly respond to changes in sunlight, adjusting the angle of the photovoltaic panel in real time to ensure optimal energy efficiency. It employs simple mechanical and fluid dynamics principles, reducing complex electronic control components and enhancing stability and reliability.

[0038] The photovoltaic module protrudes upward from the driver unit 4 along its preset light-receiving direction. This structural arrangement allows the photovoltaic module to block at least a portion of the driver unit 4 when the incoming sunlight's propagation direction is inconsistent with the photovoltaic module's ideal light-receiving direction. This blocking effect allows the photovoltaic module to influence the degree of heating of the driving medium 6 (liquid) within the driver unit 4.

[0039] When the sun's position changes, causing the sunlight to form an angle with the PV module's light-receiving direction, the module's shadow partially obscures the driver unit 4. This obstruction reduces the amount of heat energy received by the obscured driver unit 4, while the unobstructed portion continues to receive more solar radiation, resulting in an uneven heating effect. Under sunlight, the driving medium 6 in the unobstructed driver unit 4 heats and expands, while the medium in the obscured portion heats and expands less. This temperature difference causes a difference in the liquid pressure within the inner cavity. Because the first and second cavities are connected by pipe 5, the driving medium 6 flows from areas of higher pressure to areas of lower pressure within the inner cavity. This flow drives the support end up and down, thereby adjusting the position and tilt angle of the mounting base 3. This fluid flow and oscillation of the mounting base 3 continue until the angle between the PV module's light-receiving direction and the direction of sunlight propagation is minimized, effectively returning the PV module to its optimal adjustable angle. This design enables automatic adjustment of the PV panel's angle at different times of day to maximize energy capture efficiency. It can adjust the angle of the photovoltaic panel without external power supply, simply through physical response under natural lighting conditions; adjusting the angle through natural thermodynamic processes rather than electromechanical equipment reduces energy consumption and potential maintenance costs; it responds to changes in sunlight quickly and with high accuracy, and can effectively track the dynamic changes of sunlight.

[0040] In summary, the base 1 is circumferentially provided with multiple first support portions 2, designed to allow the photovoltaic module to be adjusted along the desired swing direction. The first support portions 2 define a first inner cavity and include support ends that can move longitudinally within the cavity. This design allows the support ends to adjust in height based on the state of the driving medium 6, thereby changing the tilt angle of the photovoltaic module.

[0041] The lower portion of the mounting base 3 is connected to the support end, while its upper portion is designed for mounting photovoltaic modules. Multiple drive units 4 are arranged circumferentially. A second internal cavity is formed within the drive unit 4, connected to the first internal cavity via a conduit 5. This allows a drive medium 6, a liquid that expands when exposed to sunlight, to flow between the two cavities. When the angle of sunlight changes, causing the photovoltaic module to block the drive unit 4, the degree of heating of the liquid within the drive unit 4 changes. This change in heating causes the liquid to expand or contract differently, which is then transferred through the conduit 5 to the first internal cavity, affecting the position of the support end and ultimately adjusting the tilt angle of the mounting base 3 and the photovoltaic module. By dynamically adjusting the angle of the photovoltaic panels to match the position of the sun, the absorption and conversion efficiency of solar energy is maximized. The use of a solar-thermal-driven automatic adjustment mechanism avoids the additional energy consumption of motors and electronic sensors, reducing overall operating costs. It allows the photovoltaic system to more effectively adapt to varying environmental conditions and changes in sunlight, improving overall performance and reliability. By simplifying the mechanical structure and reducing the number of electronic control components, it reduces initial investment and maintenance costs.

[0042] Specifically, the driving part 4 can be a light-transmitting pipe 5, which is usually made into a cylindrical shape and can be made of transparent or translucent materials (such as certain types of plastic or glass); the collector container is a container used for efficient heat collection and heat transfer, which may include an internal coating or a specially designed shape to enhance its heat capture ability.

[0043] Specifically, the driving medium 6 can be certain specific liquids with a high thermal expansion coefficient. When heated, the volume increases significantly. The volume change can be directly converted into mechanical force to drive the movement of the supporting structure. Examples include but are not limited to mineral oil, silicone oil, etc. These oils perform well in terms of thermal expansion.

[0044] In any of the above embodiments, the first supporting portion 2 further includes:

[0045] The first shell 201 is connected to the base 1 through an elastic component. The compression spring 8 provides elastic support and upward support force to the first shell 201. Through different compression degrees of the spring 8, predetermined directions for different areas to receive sunlight can be provided during the initial installation.

[0046] The first rod body 202 is sleeved inside the first shell 201, and the inner wall of the first shell, the outer wall of the first rod body 202 and the support end form a first inner cavity, so that the space of the first inner cavity to receive the driving medium 6 is an annular structure, which is conducive to providing a larger driving stroke for the driving medium 6 under the same volume expansion.

[0047] The support end is located between the first shell 201 and the first rod body 202, so that the support end is a circumferential ring structure, which is conducive to the pushing of the driving medium 6, and the first shell 201 supports the support end through the driving medium 6 in the first inner cavity.

[0048] In this embodiment, the first shell 201 serves as the main support structure, and the first shell 201 is directly connected to the base 1 for fixing and supporting the photovoltaic panel; the elastic assembly is generally a structure capable of elastic compression, and is installed between the first shell 201 and the base 1 for providing an upward elastic support force.

[0049] In the initial installation stage, the height and inclination angle of the first shell 201 can be adjusted according to different pre-compression settings by compression. Such settings allow the installer to pre-set the optimal sunlight receiving direction according to the geographical location and typical sunlight conditions of the photovoltaic panel installation site; the sunlight intensity and angle may be different in different regions, and by adjusting the compression degree of the spring 8, the initial inclination angle of each photovoltaic panel can be optimized to match the sunlight angle of the specific installation site; in daily operation, as the position of the sun changes, it may be necessary to fine-tune the angle of the photovoltaic module to maintain optimal light reception. The first shell 201 achieves this through the built-in or connected adjustment mechanism such as the driving medium 6 affected by the hydraulic pressure; the compression elastic property allows the first shell 201 to produce a certain movement or inclination under external force, thereby responding to changes in sunlight. The elastic force of the spring 8 also helps to return to the initial or optimal position without the need for external energy input; the elastic support not only helps dynamic adjustment, but also provides necessary anti-seismic and wind resistance. In strong winds or bad weather, the spring 8 can absorb part of the impact of external forces, reducing the force directly acting on the photovoltaic panel and the support structure, protecting the equipment from damage.

[0050] The first shell 201 provides basic structural support and protection while forming the outer wall of the first inner cavity; the first rod body 202 is sleeved inside the first shell 201 and cooperates with the first shell 201 to form the structure of the first inner cavity, and the first rod body 202 is designed to maintain a certain gap with the first shell 201, thereby forming a ring-shaped first inner cavity; the support end is located at the lower end of the first inner cavity and is connected with the ring-shaped inner cavity, participating in the dynamic adjustment of the driving medium 6 in the inner cavity.

[0051] The annular inner cavity design allows the driving medium 6 to provide a greater driving stroke under the same volume expansion conditions through the geometric characteristics of the annular space. This is because the annular space can produce a larger surface area change within a relatively small volume change, resulting in a more significant pressure change. The annular structure helps to more evenly distribute the pressure of the driving medium 6 within the inner cavity, reducing mechanical stress and wear caused by uneven pressure. When sunlight shines on the driving part 4 of the photovoltaic module, the driving medium 6 (such as a special thermal expansion liquid) in the inner cavity is heated. The thermal expansion of the driving medium 6 causes the internal pressure to increase. As the pressure in the inner cavity increases, this pressure change drives the support end to move, thereby adjusting the inclination angle of the assembly base 3 and the photovoltaic panel. The temperature and pressure changes of the driving medium 6 directly affect the position of the support end, allowing the assembly base 3 to automatically adjust the tilt angle of the photovoltaic panel according to changes in sunlight conditions. This automatic adjustment ensures that the photovoltaic panel always receives sunlight at the optimal angle, maximizing power generation efficiency.

[0052] The support end is located within the annular space between the first shell 201 and the first rod 202, forming an annular structure. This design allows the support end to evenly absorb pressure from the first inner cavity along its circumference. The annular support end is made of elastic or rigid material and, depending on design requirements, can provide necessary mechanical support or allow a certain degree of elastic deformation. The first inner cavity is enclosed by the first shell 201 and the first rod 202, forming a closed or semi-closed liquid environment. The interior is filled with a driving medium 6 (typically a thermal expansion liquid). The driving medium 6 expands when heated, driving the movement of the support end by changing the pressure in the inner cavity.

[0053] When sunlight shines on the photovoltaic modules connected to the support structure or directly shines on the driving part 4, the driving medium 6 expands due to heat. As the volume of the driving medium 6 increases, the pressure in the inner cavity increases. This pressure increase generates an outward or upward force on the support end, pushing the support end to move on its annular track; the movement of the support end causes the position and tilt angle of the entire assembly seat 3 to change. Due to the annular design of the support end, this change is uniform in the circumferential direction, ensuring uniform adjustment of the photovoltaic module angle. The uniform pressure distribution and the annular structure of the support end make the adjustment of the assembly seat 3 smoother and more coordinated, improving the efficiency and accuracy of the response to changes in the sun's angle; through the uniform and continuous adjustment of the annular support end, the photovoltaic panel always captures sunlight at the optimal angle, maximizing the energy capture and conversion efficiency of the photovoltaic panel. This design also improves the overall stability of the structure and reduces the risk of wear and damage due to non-uniform loads or uneven distribution of force.

[0054] In any of the above embodiments, the elastic component includes:

[0055] Support plate 7; a groove 101 is provided on the upper surface of the base 1, and one end of the support plate 7 is slidably mounted on the inner wall of the groove 101; the other end of the support plate 7 is rotatably connected to the lower surface of the first shell 201, and the height of the top end of the support plate 7 is adjusted by moving the bottom of the support plate 7 to meet the requirements of different heights of the first shell 201.

[0056] The spring 8 is arranged inside the groove 101 to reduce the interference of external debris; one end of the spring 8 is fixedly connected to the inner wall of the groove 101, and the other end of the spring 8 is connected to the support plate 7, so that the height of the top of the support plate 7 can be adjusted. With the different adjustments of multiple support plates 7, the direction and angle with the minimum required swing amplitude can be set during the initial installation; the length of the spring 8 is used to adjust the height of the support end relative to the base 1, and the length model of the spring 8 can be selected according to actual use.

[0057] In this embodiment, support plate 7 is a mechanical component used to connect base 1 and first housing 201. One end of the support plate 7 is slidably mounted on the inner wall of groove 101 in base 1, while the other end is pivotally connected to the lower surface of first housing 201. The design of support plate 7 allows its bottom to slide along groove 101 in base 1, while its top can rotate or tilt to adjust the position and height of first housing 201. A groove 101 is defined on the upper surface of base 1 to guide and limit the sliding of support plate 7. This groove 101 ensures the direction and range of movement of support plate 7 while providing necessary mechanical support.

[0058] The height of the top end of support plate 7 (the end connected to first housing 201) can be adjusted by manually or automatically controlling the sliding position of the bottom of support plate 7 within groove 101. Because the top end of support plate 7 is pivotally connected to first housing 201, this height change directly affects the vertical position and tilt angle of first housing 201. This structural design allows for precise control of the height and angle of first housing 201 to adapt to different operational requirements or changes in solar angle, optimizing the energy capture efficiency of the photovoltaic module. In applications where the angle of the photovoltaic panel needs to be dynamically adjusted based on sunlight conditions, the movement of support plate 7 can be driven by sensor data to ensure that the photovoltaic panel always maintains the optimal angle for receiving sunlight. The design of support plate 7 also allows for rapid response and adjustment, allowing the entire support structure to quickly adapt to environmental changes, improving overall efficiency and output. The mechanical connection of support plate 7 (sliding and pivoting connection) provides a stable and reliable support mechanism, and this stability helps maintain the performance of the photovoltaic panel in adverse weather conditions.

[0059] Spring 8 is mounted within groove 101 of base 1. This mounting method helps protect spring 8 from external debris and environmental factors. One end of spring 8 is fixedly connected to the inner wall of groove 101, while the other end is connected to support plate 7. This connection method provides height adjustability and elastic support for support plate 7. Groove 101 is designed to guide and support the movement of spring 8 and support plate 7, ensuring overall structural stability and accurate movement. The connection between support plate 7 and spring 8 provides the necessary elasticity and adjustability, allowing the height of its top end to be adjusted according to the tension or compression of spring 8.

[0060] By adjusting the compression or extension of the spring 8, the height of the support plate 7 can be flexibly adjusted, thereby changing the height of the first shell 201 connected to the support plate 7. During the initial installation, the optimal swing amplitude and angle of the photovoltaic module can be preset by selecting springs 8 of different lengths or models to adapt to specific geographical and environmental conditions; the elastic characteristics of the spring 8 allow the support plate 7 to be dynamically adjusted under external loads or environmental changes (such as wind influence), ensuring that the photovoltaic panel always remains in the best state to receive sunlight. The design of the spring 8 also allows for rapid response to changes in sunlight angle, improving adaptability to changes in sunlight; the built-in installation of the spring 8 reduces damage or performance degradation that may be caused by the intrusion of external debris, enhances reliability and durability, and through the coordinated work of multiple support plates 7 and springs 8, the load can be evenly distributed, thereby improving overall stability and efficiency.

[0061] In any of the above embodiments, at least two grooves 101 are configured along the circumference of the first rod body 202, and the number of support plates 7 on the same first shell 201 is adjusted by the number of grooves 101 to adjust the total supporting elastic force; the spring 8 is in a compressed state inside the groove 101, so that when the driving medium 6 drives the support end to move longitudinally, it applies a force to the first shell 201 through the support plate 7.

[0062] In this embodiment, at least two grooves 101 are provided on the circumference of the first rod 202. These grooves 101 are evenly distributed and are used to install springs 8 and support plates 7. This design allows the support plates 7 to be evenly distributed around the first housing 201, providing a balanced supporting force. By increasing or decreasing the number of grooves 101, the number of support plates 7 can be adjusted accordingly, thereby adjusting the total supporting elastic force applied to the first housing 201. A spring 8 is installed within each groove 101. These springs 8 are installed in a compressed state to provide a predetermined elastic force. One end of the support plate 7 is connected to the spring 8, and the other end is rotatably connected to the first housing 201. This allows the support plate 7 to move upward or downward under the action of the spring 8, thereby adjusting the position of the first housing 201.

[0063] By adjusting the number and degree of compression of springs 8 in groove 101, the total elastic force applied to first shell 201 can be precisely controlled, facilitating adjustment according to different installation conditions and load requirements. When driving medium 6 drives the support end to move longitudinally, the compressed state of spring 8 allows for rapid release or absorption of energy, thereby effectively adjusting the height and tilt angle of first shell 201. The support plates 7 are evenly arranged around first rod 202, ensuring uniform distribution of force on first shell 201. This not only improves structural stability but also reduces potential damage caused by uneven forces. When driving medium 6 undergoes thermal expansion or contraction, spring 8 can flexibly adjust its degree of compression through mechanical transmission via support plates 7, thereby causing first shell 201 to make corresponding positional adjustments. Through this flexible elastic force adjustment mechanism, the photovoltaic support structure can maintain optimal operating performance under changing environmental conditions, ensuring that the photovoltaic modules always capture sunlight at the optimal angle. Through dynamic adjustment, energy capture can be maximized, improving the energy efficiency and production efficiency of photovoltaic panels.

[0064] In any of the above embodiments, the support end includes:

[0065] The second shell 203 has a third inner cavity formed on its inner wall; the first rod body 202 is sleeved inside the second shell 203 through the third inner cavity to guide the movement of the second shell 203, and the top of the second shell 203 is hinged to the lower part of the assembly seat 3 to adapt to the movement of multiple second shells 203.

[0066] The extended edge 204 is circumferentially arranged on the bottom outer edge of the second shell 203; the extended edge 204 is used to divide the first inner cavity and block the driving medium 6, and the first inner cavity located below the extended edge 204 is filled with the driving medium 6. The extended edge 204 can block the driving medium 6 and enable the driving medium 6 to drive the extended edge 204 and the second shell 203 to move longitudinally.

[0067] In this embodiment, the second housing 203 is designed to surround the first rod 202. Its inner wall forms a space, called a third inner cavity, for receiving the first rod 202. The top of the second housing 203 is designed to be hinged, enabling it to connect to the lower portion of the assembly base 3. The third inner cavity is formed inside the second housing 203 and mates with the outer wall of the first rod 202. This design allows the second housing 203 to move vertically or at a slight angle under the guidance of the first rod 202. The top of the second housing 203 is connected to the lower portion of the assembly base 3 via a hinge. This connection allows the second housing 203 to rotate or tilt appropriately when necessary to accommodate the dynamic adjustment requirements of the entire support structure.

[0068] The second housing 203 is guided along the first rod 202 by a sleeve connection within the third inner cavity. This structural arrangement allows for smoother and more precise movement of the second housing 203, helping to maintain the proper position and angle of the mounting base 3 and the attached photovoltaic module. The first rod 202 provides a sturdy guide for the second housing 203, ensuring its correct trajectory and reducing deviation and friction. The hinge mechanism allows the second housing 203 to be adjusted as needed between its top and the mounting base 3. This feature is designed to accommodate varying installation angles and terrain conditions, particularly when multiple second housings 203 are operating simultaneously, maintaining the overall structure's consistency. This flexible connection also helps absorb minor displacement or expansion caused by environmental changes, such as wind pressure and temperature differences. The structure and hinged connection of the second housing 203 provide enhanced stability, ensuring that the mounting base 3 and the photovoltaic panel remain in the optimal operating position. The hinge point design also allows for fine-tuning the position of each second housing 203 to balance the entire assembly structure when encountering asymmetric loads or uneven terrain.

[0069] Extended edge 204 is an outer edge of the bottom of second shell 203, extending around the circumference. It extends the physical boundaries of second shell 203 and enhances the overall stability of the structure. This structure acts as a physical barrier, dividing the first inner cavity and blocking the driving medium 6 within. The first inner cavity, located below extended edge 204, is filled with driving medium 6 (such as a specific liquid or gas), which can change volume or state in response to temperature changes or external pressure.

[0070] The extended edge 204 physically blocks the driving medium 6 in the first inner cavity below it. This blocking effect ensures that the driving medium 6 is effectively concentrated within a predetermined space, thereby improving driving efficiency. When the driving medium 6 expands due to heat or other mechanical effects and increases in volume, the presence of the extended edge 204 limits the escape path of the driving medium 6, forcing it to exert pressure upward or in a specific direction. The pressure change of the driving medium 6 directly acts on the extended edge 204, causing the entire second shell 203 to move longitudinally. This movement is achieved through the coordinated design of the extended edge 204 and the second shell 203 structure, allowing the position of the second shell 203 to be precisely adjusted. This longitudinal movement is crucial for adjusting the position of the assembly base 3 and the photovoltaic module, especially when the angle needs to be automatically adjusted according to the position of the sun to maximize energy capture. The design of the extended edge 204 not only improves response speed and sensitivity, but also enhances stability and reliability under different environmental conditions. This design enables the photovoltaic support structure to respond more accurately to environmental changes, thereby optimizing the energy conversion efficiency and output performance of the photovoltaic panel.

[0071] In any of the above embodiments, the driving portion 4 and the pipe 5 are made of a light-transmitting material so as to be heated by sunlight;

[0072] The part of the pipe 5 close to the first shell 201 is spirally wrapped around the first rod body 202, and can be heated by light for the second time at the end; along the swing direction of the assembly seat 3, a sunshade 10 for circumferentially shielding the pipe 5 is installed on the base 1. Through the cooperation of the sunshade 10, the spirally wrapped part of the pipe 5 can start the supplementary heating of the driving medium 6 in the pipe 5 close to the first inner cavity when the sunlight is inclined at a high degree, so as to increase the expansion volume difference of the driving medium 6 between the driving part 4 that is exposed to light and the driving part 4 that is not exposed to light.

[0073] In this embodiment, the drive unit 4 and the pipe 5 are made of a translucent material, which enables the entire drive to be directly heated by sunlight. The translucent material allows sunlight to penetrate and directly heat the driving medium 6 (such as a special liquid or gas) in the pipe 5, thereby utilizing solar energy to generate thermal expansion. The pipe 5 is designed to be spirally wound around the first rod 202 in the portion close to the first shell 201. This design increases the surface area of ​​the pipe 5, thereby improving the heat absorption efficiency. The spiral design also enables the pipe 5 to be heated by light for a second time at the end, and can effectively capture sunlight even when the sun is tilted at a large angle. Sunshades 10 are installed on the base 1 along the swinging direction of the assembly seat 3. These sunshades 10 are used to periodically block the pipe 5, especially the spirally wound portion, to control the amount of sunlight received by the pipe 5. The design of the sunshades 10 enables them to timely block part of the pipe 5 when the inclination of the sunlight is high, thereby regulating the heat of the light-receiving area of ​​the pipe 5.

[0074] The driving medium 6 is directly heated by sunlight in the pipe 5 made of translucent material. This heating causes the medium to expand, and the resulting pressure change is used to drive the adjustment mechanism of the support structure. The spiral design of the pipe 5 increases the heating efficiency, ensuring that sufficient thermal expansion force can continue to be generated even when the sunlight is weak or the angle changes; the sunshade 10 controls the heating degree of the driving medium 6 in the pipe 5 by periodically blocking part of the spiral pipe 5. This control allows the driving force to be dynamically adjusted according to the intensity and angle of the sunlight. When the sunlight is highly inclined, the sunshade 10 can reduce the solar exposure to the illuminated part of the pipe 5, and start supplementary heating of the driving medium 6 in the pipe 5 close to the first inner cavity, further increasing the expansion volume difference of the driving medium 6 between the illuminated and non-illuminated driving parts 4.

[0075] In any of the above embodiments, the assembly seat 3 includes a first seat body 301 connected to the support end and a second seat body 302 for assembling the photovoltaic module. Through the separate setting of the first seat body 301 and the second seat body 302, the driving part 4 and the photovoltaic module can be shielded to increase the impact of oblique sunlight on different driving parts 4.

[0076] The first seat body 301 and the second seat body 302 are connected by the second support part 303, and the second support part 303 is internally formed with a fourth inner cavity in communication with the second inner cavity, and the fourth inner cavity can accommodate the driving medium 6, so that the second seat body 302 can oscillate circumferentially relative to the first seat body 301.

[0077] In this embodiment, the first seat body 301 is connected to the support end as the interface of the assembly seat 3 and the support structure. It provides the necessary mechanical support and stability for the assembly seat 3, and this seat body can be designed as an adjustable structure to adjust its position and angle according to different operation requirements and installation conditions; the second seat body 302 is specially used for assembling and fixing the photovoltaic module. Its design allows the photovoltaic module to maintain the best light-capturing angle while facilitating installation and maintenance, and the second seat body 302 is usually designed to be adjustable to adapt to different angles of sunlight and optimize the energy capture efficiency of the photovoltaic module.

[0078] Through the split design of the first seat body 301 and the second seat body 302, the assembly seat 3 can form a shielding area between the driving part 4 and the photovoltaic module. This shielding is crucial for managing and optimizing the impact of oblique sunlight, especially in cases where the angle of sunlight changes greatly. The shielding area helps control the extent to which sunlight directly hits the driving part 4, and by reducing or increasing the illumination of certain driving part 4 sections, the temperature and corresponding expansion rate of the driving medium 6 can be adjusted, thereby precisely controlling the movement of the support structure; the design of the first seat body 301 and the second seat body 302 allows the assembly seat 3 to dynamically adjust the position of the photovoltaic module when the angle of sunlight changes. This adjustment is achieved by affecting the heating degree and corresponding expansion force of the driving part 4, thereby optimizing the response of the entire structure to sunlight. The dynamic adjustment capability of the assembly seat 3 ensures that the photovoltaic module always maintains the best light-capturing angle, maximizing energy capture and conversion efficiency.

[0079] The second support part 303 connects the first seat body 301 and the second seat body 302, allowing relative movement between the two. The key to the design of this part lies in the fourth inner cavity formed inside, which is in communication with a larger second inner cavity, and the fourth inner cavity is designed to accommodate driving medium 6, such as special liquids or gases, which change in volume under thermal expansion or other physical changes; the first seat body 301 is mainly connected to the support end and the second support part 303, while the second seat body 302 is specially used for assembling and supporting the photovoltaic module, and the two seat bodies are connected through the second support part 303, ensuring the overall stability of the structure while providing the necessary degree of freedom of movement.

[0080] When the driving medium 6 (located in the fourth inner cavity) expands due to heat, since the fourth inner cavity is connected to the second inner cavity, the increase in internal pressure will drive the second support part 303 to produce corresponding mechanical movement. The mechanical movement caused by this internal pressure change enables the second base 302 to swing circumferentially relative to the first base 301, adjusting the angle of the photovoltaic module to better capture sunlight; the design of the second support part 303 allows the second base 302 to swing freely along the circumference when necessary. This swing is directly controlled by the change in the physical state of the driving medium 6. This swinging ability is crucial for automatically adjusting the tilt angle of the photovoltaic module to adapt to changes in sunlight angle, especially in areas with changeable sunlight conditions; by utilizing the thermal energy of sunlight to directly drive the swing of the second base 302, no external energy input is required, it can respond to environmental changes, and improve energy conversion efficiency. The inner cavity design of the second support part 303 ensures the effective utilization of the driving medium 6, so that the response speed and adjustment accuracy of the entire support structure are optimized.

[0081] Specifically, the second support part 303 includes a third shell 3031 installed on the first base body 301 and a push rod 3032 slidably installed on the inner wall of the fourth inner cavity. The push rod 3032 is hinged to the second base body 302, and the driving medium 6 inside the fourth inner cavity can push the push rod 3032 to perform telescopic movement relative to the third shell 3031.

[0082] As can be seen above, third housing 3031 is mounted on first base 301, forming the main structure of the fourth inner cavity. This housing is fixed, providing a stable enclosure to house and protect the internal mechanical components and drive medium 6. The design of third housing 3031 ensures the inner cavity is isolated from the external environment and also provides guidance for the movement of push rod 3032 inside. Push rod 3032 is slidably mounted on the inner wall of the fourth inner cavity, capable of telescopic movement. This telescopic movement is directly driven by the pressure changes of drive medium 6 within the inner cavity. One end is hinged to second base 302. This hinged design allows push rod 3032 to transmit force while also providing the necessary freedom of movement to accommodate the angular adjustment of second base 302.

[0083] When the driving medium 6 (such as a specific heat-sensitive liquid or gas) in the fourth inner cavity is heated and expands, its volume and pressure increase, and this increased pressure directly pushes the push rod 3032 to perform a telescopic motion. The pressure change of the driving medium 6 is thus directly converted into mechanical motion of the push rod 3032, causing the push rod 3032 to extend outward or retract inward, dynamically adjusting its length according to changes in sunlight conditions; the telescopic motion of the push rod 3032 enables the second seat body 302, which is hinged to it, to perform a circumferential swing relative to the first seat body 301. This swing is the key to precisely controlling the angle of the photovoltaic module, especially when the position of the sun changes, which can optimize the sunlight reception of the module. The hinge point allows necessary angle adjustment while maintaining the entire mechanical connection and force transmission; this push rod 3032 motion controlled by the driving medium 6 achieves a rapid and precise response to changes in the angle of sunlight, automatically adjusting the inclination angle of the photovoltaic panel to maximize energy capture efficiency, allowing continuous and smooth motion adjustment, reducing mechanical wear and improving operating efficiency.

[0084] In any of the above embodiments, the driving part 4 drives the first seat body 301 to move away from the side of the current driving part 4 through the first support part 2 that is longitudinally staggered, so that when the driving part 4 on one side of the photovoltaic module receives more light, it can drive the support end on the other side of the photovoltaic module to move longitudinally more, so that the driving part 4 on the other side that receives less light can receive more sunlight and heat the internal driving medium 6 through swinging, until the forces received by the photovoltaic module are equal, at which point the maximum degree of the included angle can be reduced.

[0085] The driving part 4 also drives the second seat body 302 to move closer to the side of the current driving part 4 through the second support part 303 located on the other side of the photovoltaic module, so that the photovoltaic module can improve the shading of the driving part 4 on the other side, further enhancing the condition of the driving part 4 on the side that does not receive light, indirectly increasing the advantage of the driving part 4 that receives light over the driving part 4 that does not receive light, to increase the adjustment force of the assembly seat 3.

[0086] In this embodiment, the driving part 4 is arranged on both sides or around the photovoltaic module, and each driving part 4 is connected to the first seat body 301 through the corresponding support part. The driving part 4 contains a driving medium 6 that can respond to sunlight, usually a specific liquid or gas that expands when heated; the first support part 2 is designed to be longitudinally staggered and driven, meaning that the driving part 4 and the first support part 2 are arranged spatially staggered to independently respond to the power from the driving part 4 on the opposite side. This configuration enables the first support part 2 to push the first seat body 301 to move away from the side of the current driving part 4 that receives more light according to the different light receiving conditions of the driving part 4.

[0087] When the driving portion 4 on one side of the photovoltaic module receives more sunlight and the driving medium 6 expands, the driving force on that side increases. Through the first support portion 2 driven in a longitudinally staggered manner, this increased driving force pushes the first seat body 301 to move the assembly seat 3 as a whole to the opposite side. This movement actually reduces the light blocking of the driving portion 4 on the side that receives less light, allowing the driving portion 4 on this side to receive more sunlight and heat the driving medium 6 inside it. Through the application of this asymmetric force, the tilt angle of the photovoltaic panel is automatically adjusted to reduce the difference in force on both sides of the photovoltaic panel until the forces on both sides tend to balance. This automatic adjustment ensures that the photovoltaic module can maximize the capture of sunlight throughout the entire sunlight cycle, reducing energy loss caused by uneven illumination.

[0088] The second support portion 303 is connected to the second base body 302 and is responsible for transmitting the driving force from the driving portion 4 to the second base body 302. The design of the second support portion 303 allows the second base body 302 to move toward the side where the current driving portion 4 receives more light, which helps to adjust the overall position and angle of the photovoltaic module; the driving portion 4 contains a sensitive driving medium 6, which will produce different expansion reactions when exposed to different degrees of sunlight. The driving portion 4 transmits force to the support portion through a physical connection, affecting the tilt and swing of the photovoltaic module.

[0089] When the driving part 4 on one side of the photovoltaic module receives more sunlight, the driving medium 6 on that side expands and pushes the first seat body 301 to move to the other side through the first support part 2 to reduce the light receiving angle of the photovoltaic module. At the same time, the second support part 303 on the other side responds to the opposite force and pushes the second seat body 302 to the side receiving more light, further enhancing the shielding of the side receiving less light. The purpose of this is to increase the difference in light conditions on both sides so that the entire photovoltaic module can receive sunlight more evenly; by increasing the dynamic difference between the driving part 4 on the light-receiving side and the non-light-receiving side, the adjustment force of the assembly seat 3 can be increased, thereby more effectively controlling the tilt angle of the photovoltaic module. This adjustment strategy makes the influence of the driving part 4 on one side more significant, while the other side reduces light by increasing shielding, thereby achieving the purpose of dynamically balancing the light received by the photovoltaic module.

[0090] In any of the above embodiments, all the first rod bodies 202 are arranged circumferentially around an axis, and a push rod 9 is installed at the intersection of the base 1 and the axis. The top of the push rod 9 abuts against the lower surface of the first seat body 301. Specifically, a universal joint structure formed by a sphere and an inner concave seat body is adopted to adapt to the swing of the assembly seat 3.

[0091] In this embodiment, the top rod 9 is located at the intersection of the base 1 and the axis, and is typically installed vertically. The top rod 9 is designed to support the entire assembly base 3 structure and transmit forces from the assembly base 3 to the base 1. The top of the top rod 9 is designed to abut the lower surface of the first base 301, forming a stable connection point. At the contact point between the top of the top rod 9 and the first base 301, a universal joint structure consisting of a sphere and a corresponding concave base is used. This universal joint allows the assembly base 3 to swing freely in multiple directions, providing the necessary freedom of movement to adapt to different sunlight angles and environmental changes.

[0092] The universal joint design allows the first base 301 (directly connected to the PV module) to rotate and tilt in nearly any direction. This flexible movement is achieved by allowing the sphere to rotate freely within the recessed housing. This structure is particularly suitable for applications requiring precise angle adjustment to maximize solar energy capture efficiency, as it allows the PV module to be flexibly adjusted based on the sun's real-time position. The universal joint not only provides freedom of movement but also helps maintain the stability of the entire PV panel during adjustment at various angles. The contact surface between the sphere and the recessed housing provides uniform force distribution, reducing localized pressure points and thus reducing the risk of wear and failure. When the PV module needs to be adjusted to the optimal light-harvesting angle, the universal joint ensures smooth adjustment, avoiding mechanical stress and structural damage. Because the universal joint allows for instant and multi-angle adjustment, the PV support structure can quickly respond to environmental changes, especially in regions with rapidly fluctuating sunlight conditions. This rapid and precise adjustment capability ensures that the PV system remains in the optimal position for maximum sunlight at any given moment, thereby improving overall efficiency and output performance.

[0093] In any of the above embodiments, the top rod 9 and the base 1 are hollow, the pipe 5 passes through the outer wall of the first base body 301 and the top rod 9, and extends through the interior of the top rod 9 and the base 1 to reduce the possibility of the pipe 5 receiving sunlight where it does not need to be exposed to light.

[0094] In this embodiment, the top rod 9 and base 1 employ a hollow structure, which not only reduces the overall weight of the structure but also provides space for the installation of the internal pipe 5. This hollow configuration allows the internal pipe 5 to extend along the top rod 9 and base 1, effectively isolating the pipe 5 from direct contact with the external environment. The pipe 5 extends from the first base 301 through the inner wall of the top rod 9 to the base 1, forming a closed fluid transmission path. This arrangement helps protect the driving medium 6 within the pipe 5 from direct external influences. This internal arrangement of the pipe 5 also helps maintain a stable temperature of the driving medium 6, preventing thermal fluctuations caused by direct sunlight.

[0095] By arranging the pipes 5 inside the hollow top rod 9 and base 1, the possibility of the pipes 5 that do not need to be exposed to sunlight being exposed to sunlight can be effectively reduced. This helps prevent unnecessary increases in internal temperature and protects the driving medium 6 from overheating. This design reduces the instability of the driving medium 6 performance caused by ambient temperature fluctuations, thereby improving the overall operational efficiency and reliability. The arrangement of the pipes 5 within the hollow structure helps maintain the temperature of the driving medium 6 stable, especially in direct sunlight or high-temperature environments, preventing performance fluctuations caused by excessive thermal expansion. This temperature control is achieved through physical isolation and the natural cooling effect of the top rod 9 and base 1, helping to maintain overall thermal balance. Through this internal pipe 5 arrangement, the thermal energy of the driving medium 6 can be more effectively managed, ensuring that only the necessary parts are heated, thereby optimizing energy use and conversion efficiency. This efficient energy management not only improves the response speed and adjustment accuracy of the photovoltaic module, but also extends its entire service life.
