Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic aluminum frame technology, specifically to a deformation-resistant solar photovoltaic aluminum frame. Background Technology

[0002] As is well known, solar photovoltaic modules are deployed outdoors for extended periods and must withstand multiple external forces such as strong winds, snow accumulation, temperature deformation, and installation stress. As the core component for supporting, protecting, and fixing photovoltaic panels, the structural strength, deformation resistance, and splicing stability of the photovoltaic modules directly determine the service life and power generation safety of the photovoltaic modules. Therefore, there are stringent requirements for the high strength, deformation resistance, and stable connection of the frame.

[0003] Traditional aluminum frames are mostly single-profile splicing structures, with no bottom reinforcement support or rib design. The overall bending, torsional and compressive strength is insufficient. Under long-term wind and snow loads and temperature stress, they are prone to plastic deformation such as bending, twisting and warping, which can lead to uneven stress on the photovoltaic panel, causing hidden cracks and damage. At the same time, the splicing of the frame is only fixed with simple bolts, without precise alignment and interlocking and multiple locking and limiting structures. The splicing gaps are large and the connection rigidity is low. Thermal expansion and contraction can easily cause the splicing to loosen and misalign, further aggravating the overall deformation.

[0004] Therefore, a deformation-resistant aluminum frame for solar photovoltaic systems is needed. Summary of the Invention

[0005] In order to overcome the problems of insufficient overall bending, torsion and extrusion strength, large splicing gaps and low connection stiffness of existing anti-deformation solar photovoltaic aluminum frames, this invention provides an anti-deformation solar photovoltaic aluminum frame. Technical solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a deformation-resistant aluminum frame for solar photovoltaic systems, comprising: Solar panels; The frame body is detachably mounted on the outside of the solar panel, and the frame body is divided into four parts; A reinforcing component, the reinforcing component being mounted on the bottom of the frame body; and A fixing component is installed between the frame bodies. The fixing component includes a fixing plate, which is detachably disposed on the top of the frame body. Vertical plates are fixedly disposed on both sides of the fixing plate, and the vertical plates are detachably disposed from the frame body. A locking device is installed on the top of the fixing plate.

[0007] Preferably, a fixing block is fixedly provided on the top of the adjacent frame body, the top of the fixing block is detachably provided with the bottom of the fixing plate, and rubber pads are fixedly provided on both sides of the vertical plate, the rubber pads being in contact with the sides of the fixing block.

[0008] Furthermore, a limiting hole is provided on the fixing block, and a limiting post adapted to the limiting hole is slidably provided on the vertical plate. A baffle is fixedly provided on the side of the limiting post, and a spring is fixedly provided on the baffle. The spring is sleeved on the limiting post.

[0009] Furthermore, the side of the frame body is provided with a sliding groove, which is L-shaped. A support rod is fixedly installed at the bottom of the vertical plate. The support rod has a number of placement slots that are the same as the number of sliding grooves. A vertical rod is slidably installed in the placement slot. The vertical rod is slidably installed with the sliding groove and the fixed plate.

[0010] In a further embodiment, a first sliding groove is provided inside the support rod, the first sliding groove is connected to the placement groove, and a slider is slidably disposed inside the first sliding groove, the slider being slidably disposed with the sliding groove.

[0011] Based on the aforementioned scheme, a slope is provided on one side of the top of the slider, and the bottom of the vertical rod is adapted to the slope. The slider is an elastic reset slider.

[0012] Furthermore, based on the aforementioned scheme, a horizontal plate is fixedly installed between the tops of the vertical rods, and a threaded handle is threaded onto the horizontal plate, which is rotatably connected to the fixed plate.

[0013] Furthermore, based on the aforementioned scheme, an alignment groove is provided on the side of one side of the frame body, and an alignment block is fixedly provided on the side of the adjacent frame body, with the alignment block slidingly disposed with the alignment groove.

[0014] Furthermore, based on the aforementioned solution, the reinforcing component includes a mounting plate, which is fixedly disposed at the bottom of the frame body. The mounting plate is detachably disposed from the solar panel. A connecting rod is fixedly disposed between the mounting plate and the connecting rod, and several reinforcing ribs are fixedly disposed at the top of the connecting rod.

[0015] Furthermore, based on the aforementioned solution, a stop bar is fixedly installed at the top of the frame body, and the stop bar is in contact with the top of the solar panel. Beneficial effects

[0016] This anti-deformation solar photovoltaic aluminum frame solves the core problems of traditional solar photovoltaic aluminum frames, which are spliced ​​from a single profile without bottom reinforcement, resulting in insufficient bending, torsional, and compressive strength. They are also prone to plastic deformation under long-term loads and temperature differences. Furthermore, the splicing joints are only fixed with simple bolts, lacking precise alignment and multiple locking mechanisms, leading to large gaps, low connection rigidity, and easy loosening and misalignment. The alignment groove and alignment block achieve precise interlocking splicing of the frame, while the bottom connecting rod and reinforcing ribs provide strong support, significantly improving the frame's bending, torsional, and compressive strength. Spring-loaded limit posts, L-shaped sliding grooves, and linkages between the vertical rod and slider form a multiple locking structure, ensuring a firm, non-loose splicing with small gaps, resisting the effects of thermal expansion and contraction. The stop bar and rubber pad ensure stable positioning and sealing of the photovoltaic panel. This dual optimization of structural strength and splicing stability completely avoids frame bending, twisting, and warping deformation, preventing microcracks and damage to the photovoltaic panel due to uneven stress, significantly extending the lifespan of the photovoltaic module and improving outdoor operation safety.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figures 1-8 A deformation-resistant solar photovoltaic aluminum frame includes a solar panel 1, a frame body 2 detachably mounted on the outside of the solar panel 1, the frame body 2 being divided into four parts, a reinforcing component 3 installed at the bottom of the frame body 2, and a fixing component 4 installed between the frame bodies 2.

[0021] The function of solar panel 1 is to convert solar energy into electrical energy. It is the core power generation component of the solar photovoltaic module. Its surface is flat and its texture is relatively brittle, requiring a stable external structure to provide protection and support to prevent problems such as microcracks, breakage, and detachment caused by external forces such as squeezing, bending, and vibration. This directly determines the power generation efficiency and service life of the photovoltaic module. The frame body 2 is used to wrap around the outer perimeter of solar panel 1, forming an outer protective frame. It provides all-round shielding and fixation for the edges of solar panel 1, preventing damage from bumps and knocks. At the same time, it serves as the load-bearing foundation of the photovoltaic module, undertaking the core functions of installation and fixation, force transmission, and resistance to external loads. The four-piece split design facilitates rapid on-site assembly and can be flexibly spliced ​​according to the size of solar panel 1 to adapt to the usage requirements of different specifications of solar photovoltaic modules. Compared with an integrated frame, transportation and... The ease of installation is greatly improved. The function of the reinforcing component 3 is to provide reinforced support and structural reinforcement from the bottom of the frame body 2, making up for the defects of traditional aluminum frames that have no support at the bottom and poor bending and torsional resistance. Through the multi-directional force structure, it disperses the load stress brought by strong wind, snow accumulation and temperature difference, fundamentally improving the overall structural strength of the frame and preventing plastic deformation such as bending, twisting and warping of the frame. This protects the solar panel 1 from uneven external forces. The function of the fixing component 4 is to precisely splice, lock and fix the four separate frame bodies 2 in multiple ways, eliminate splicing gaps, improve the overall connection rigidity of the frame, and solve the problems of looseness, misalignment and poor sealing at the splicing points of traditional frames. This allows the four frame bodies 2 to form a stable whole, to be stressed and resist external loads simultaneously, and further enhance the deformation resistance and stability of the frame.

[0022] The fixing component 4 includes a fixing plate 5, which is detachably mounted on the top of the frame body 2. Vertical plates 6 are fixedly mounted on both sides of the fixing plate 5, and the vertical plates 6 are detachably mounted from the frame body 2. A locking device 7 is installed on the top of the fixing plate 5. The function of the fixing plate 5 is to serve as the core load-bearing component of the fixing component 4, covering the splicing gap between adjacent frame bodies 2, providing top protection and reinforcement at the splicing position, preventing vertical misalignment due to external forces, and providing a stable installation base for the vertical plates 6 and the locking device 7, ensuring the overall structural strength of the fixing component 4. The fixing plate 5 is made of the same aluminum alloy material as the frame body 2, possessing corrosion resistance, aging resistance, and deformation resistance, suitable for long-term outdoor use. The function of the vertical plates 6 is to... The two sides of the fixing plate 5 extend downwards to fit the outer wall of the frame body 2, and laterally limit the splicing position of the adjacent frame body 2 to prevent left and right displacement and widening of gaps at the splicing point. The symmetrical design of the two vertical plates 6 on both sides ensures that the force at the frame splicing point is even and the fixing effect is more stable. The vertical plate 6 and the fixing plate 5 are integrally molded structures, which are firmly connected without loosening and will not break or deform after long-term use. The function of the locking device 7 is to finally lock and fix the fixing plate 5, the vertical plate 6 and the frame body 2, so as to achieve a seamless connection between the fixing component 4 and the frame body 2 and prevent the fixing component 4 from loosening or falling off. The locking device 7 is easy to operate and can be locked and disassembled without complicated tools, which is suitable for the use of photovoltaic modules for rapid on-site installation and subsequent maintenance and disassembly.

[0023] A fixing block 8 is fixedly installed on the top of each adjacent frame body 2. The top of the fixing block 8 is detachably connected to the bottom of the fixing plate 5. Rubber pads 9 are fixedly installed on both sides of the vertical plate 6. The rubber pads 9 fit against the sides of the fixing block 8. The function of the fixing block 8 is to provide top support and docking foundation for the splicing position of the frame body 2. The fixing blocks 8 on adjacent frame bodies 2 fit against each other to achieve initial positioning of the splicing position, allowing the four frame bodies 2 to be quickly aligned when spliced, reducing installation errors. At the same time, it provides an installation matching structure for the vertical plate 6 and the limiting post 11, improving the installation accuracy of the fixing component 4. The function of the rubber pad 9 is to fill the gap between the vertical plate 6 and the fixing block 8. On the one hand, it plays a sealing and protective role, preventing outdoor rainwater, dust, and debris from entering the gap between the frame and preventing rust and dirt accumulation in the gap from affecting the stability of the connection. On the other hand, it plays a buffering and shock absorption role, absorbing the minor stress caused by strong winds and vibrations, and preventing wear and abnormal noise caused by hard contact between the vertical plate 6 and the fixing block 8. At the same time, the rubber pad 9 has a certain degree of elasticity, which can adapt to the slight thermal expansion and contraction caused by temperature differences, preventing deformation at the splice due to rigid compression, and further improving the deformation resistance of the frame.

[0024] A limiting hole 10 is provided on the fixing block 8. A limiting post 11 adapted to the limiting hole 10 is slidably provided on the vertical plate 6. A baffle 12 is fixedly provided on the side of the limiting post 11, and a spring 13 is fixedly provided on the baffle 12. The spring 13 is sleeved on the limiting post 11. The function of the limiting hole 10 and the limiting post 11 is to form an elastic limiting structure, realizing the quick engagement and fixation of the vertical plate 6 and the fixing block 8. When the vertical plate 6 is attached to the fixing block 8, the limiting post 11 is automatically inserted into the limiting hole 10 under the elastic thrust of the spring 13, completing the initial locking of the splicing position. No manual alignment and positioning are required, which greatly improves the installation efficiency. The function of the baffle 12 is to provide... Spring 13 provides a fixed support point and limits the sliding stroke of the limiting post 11, preventing the limiting post 11 from sliding excessively off the vertical plate 6 and ensuring the operational stability of the limiting structure. The function of spring 13 is to provide continuous elastic thrust to the limiting post 11, so that the limiting post 11 always maintains the tendency to be inserted into the limiting hole 10. Even in the environment of thermal expansion and contraction due to temperature difference and long-term vibration, the limiting post 11 will not come out of the limiting hole 10, ensuring that the locking state at the splice is always stable. Spring 13 is made of outdoor-specific anti-fatigue stainless steel, which is corrosion-resistant, anti-aging, and has long-lasting elasticity. It can withstand tens of thousands of expansion and contraction without failure, and is suitable for long-term outdoor use.

[0025] The side of the frame body 2 has a sliding groove 14, which is L-shaped. A support rod 15 is fixedly installed at the bottom of the vertical plate 6. The support rod 15 has a number of placement slots 16, the same as the number of sliding grooves 14. A vertical rod 17 is slidably installed in the placement slot 16. The vertical rod 17 is slidably installed with the sliding groove 14 and the fixed plate 5. The function of the sliding groove 14 is to provide a sliding limit track for the vertical rod 17. The special L-shaped design can realize the dual limitation of the vertical rod 17 in both the horizontal and vertical directions. When the vertical rod 17 is inserted into the sliding groove 14, it can not only limit the vertical movement of the vertical plate 6, but also limit the left and right displacement of the vertical plate 6, forming multiple limit locking, which further improves the fixing strength of the frame splice. The function of the support rod 15 is to provide installation support and sliding guide for the vertical rod 17, and to stably house the vertical rod 17 inside the placement slot 16. The vertical rod 17 can only slide vertically up and down without shifting or jamming. The support rod 15 and the vertical plate 6 are fixedly connected, with a solid structure that will not loosen or deform under stress. The placement groove 16 provides storage space for the vertical rod 17, allowing it to be hidden inside the support rod 15 when not locked, without occupying external space and preventing damage to the vertical rod 17 during transportation and installation. It also ensures the stability of the vertical rod 17 when sliding. The vertical rod 17 is inserted into the sliding groove 14, working with the L-shaped track to achieve deep locking between the frame body 2 and the vertical plate 6. This extends the connection between the fixing component 4 and the frame body 2 from surface fixing to internal locking, significantly improving the connection rigidity at the splicing point. This makes the adjacent frame bodies 2 form an inseparable whole, completely eliminating the problem of loosening or misalignment at the splicing point.

[0026] A first groove 18 is provided inside the support rod 15, which communicates with the placement groove 16. A slider 19 is slidably disposed within the first groove 18, and the slider 19 is slidably disposed with the groove 14. An inclined surface 20 is provided on one side of the top of the slider 19, and the bottom of the vertical rod 17 is adapted to the inclined surface 20. The slider 19 is an elastically reset slider 19. The function of the first groove 18 is to provide a sliding track for the slider 19, ensuring that the slider 19 can slide smoothly in the horizontal direction and providing power transmission for the lifting and lowering of the vertical rod 17. The function of the slider 19 is to push the vertical rod 17 up and down by sliding itself. The design of the inclined plane 20 can transform the horizontal sliding of the slider 19 into the vertical lifting of the vertical rod 17. The transmission is smooth and without jamming. The locking and unlocking of the vertical rod 17 can be achieved without additional power. The elastic reset slider 19 automatically resets when no external force is applied, keeping the vertical rod 17 locked. When disassembly is required, only a slight external force needs to be applied to push the slider 19 to move and unlock the vertical rod 17. The operation is convenient and suitable for the needs of quick disassembly and assembly on site. The slider 19 is made of wear-resistant material and will not wear or deform during long-term sliding, ensuring the stability of the transmission structure.

[0027] A horizontal plate 21 is fixedly installed between the tops of the vertical rods 17. A threaded handle 22 is threaded onto the horizontal plate 21. The threaded handle 22 is rotatably mounted to the fixed plate 5. The function of the horizontal plate 21 is to connect multiple vertical rods 17 into a whole, so as to realize the synchronous lifting and lowering of all vertical rods 17. This ensures that the locking and unlocking actions are synchronized, and avoids the locking failure caused by a single vertical rod 17 getting stuck. The horizontal plate 21 and the vertical rods 17 are fixedly connected, so the force is evenly distributed and the lifting and lowering process is smooth. The function of the threaded handle 22 is to provide manual operation power for the lifting and lowering of the vertical rods 17. By rotating the threaded handle 22, the threaded transmission drives the horizontal plate 21 to move up and down, thereby controlling the vertical rods 17 to insert into or disengage from the sliding groove 14. The threaded transmission has a self-locking function. After rotating to the designated position, it automatically locks and will not reverse or loosen due to external force or vibration, ensuring that the vertical rods 17 always maintain a stable locked state. The threaded handle 22 is easy to operate. It can be completed by manual rotation only, without the need for tools such as wrenches and screwdrivers, which greatly improves the efficiency of installation and maintenance.

[0028] One side of the frame body 2 has an alignment groove 23, and the side of the adjacent frame body 2 has an alignment block 24 fixedly installed. The alignment blocks 24 slide together. The function of the alignment groove 23 and the alignment block 24 is to achieve precise interlocking splicing of adjacent frame bodies 2. During installation, simply align the alignment block 24 of one frame body 2 with the alignment groove 23 of another frame body 2 and insert it to complete the precise positioning of the splicing position. There is no need to repeatedly adjust the alignment, which greatly reduces the installation difficulty and improves the splicing accuracy. The interlocking design eliminates splicing gaps, allowing adjacent frame bodies 2 to fit seamlessly. At the same time, it restricts the relative displacement of the frame from the side, improves the overall structural integrity of the frame, and further enhances the anti-deformation ability. The dimensions of the alignment groove 23 and the alignment block 24 are precisely matched, and the sliding is smooth. There is no looseness or offset after splicing, and there will be no problem of interlocking failure after long-term use.

[0029] The reinforcing component 3 includes a mounting plate 25, which is fixedly installed at the bottom of the frame body 2. The mounting plate 25 is detachably installed from the solar panel 1. A connecting rod 26 is fixedly installed between the mounting plates 25, and several reinforcing ribs 27 are fixedly installed on the top of the connecting rod 26. The function of the mounting plate 25 is to serve as the bottom mounting base of the reinforcing component 3, and to be fixedly connected to the bottom of the frame body 2, integrating the reinforcing component 3 with the frame body 2. At the same time, it fits the bottom of the solar panel 1, providing bottom support for the solar panel 1, preventing the bottom of the solar panel 1 from being suspended and subjected to force, and avoiding bending or cracking of the solar panel 1 due to lack of bottom support. The function of the connecting rod 26 is to connect the mounting plates 25 around the perimeter into an integral frame, forming a bottom mesh. The supporting structure disperses the external load on the frame and solar panel 1, transforming localized stress into overall stress, significantly improving the frame's resistance to bending, torsion, and compression. The connecting rod 26 adopts a multi-directional cross design, ensuring uniform stress distribution and preventing breakage or deformation due to excessive load on one side. The reinforcing ribs 27 further strengthen the structural strength of the connecting rods 26, forming vertical support ribs evenly distributed at the top of the connecting rods 26 to resist vertical snow loads and compressive stresses, while also enhancing the torsional resistance of the connecting rods 26 and preventing frame distortion. The even arrangement of multiple reinforcing ribs 27 ensures uniform strength improvement of the bottom support structure, eliminating weak points and fundamentally solving the problem of unsupported bottoms and easy deformation in traditional aluminum frames.

[0030] A stop bar 28 is fixedly installed on the top of the frame body 2. The stop bar 28 is attached to the top of the solar panel 1. The function of the stop bar 28 is to limit and fix the solar panel 1 from the top. Together with the mounting plate 25 at the bottom, it forms a two-way clamping of the solar panel 1 from top to bottom, preventing the solar panel 1 from moving up and down or falling off inside the frame. The stop bar 28 is attached to the top surface of the solar panel 1, which not only fixes it but also does not block the power generation area of ​​the solar panel 1, ensuring the normal photoelectric conversion of the solar panel 1. The stop bar 28 adopts a flexible fitting design, without rigid compression between it and the solar panel 1, avoiding damage to the edge of the solar panel 1. At the same time, it plays a sealing role, preventing rainwater from seeping into the gap between the frame and the solar panel 1 from the top, thus improving the outdoor protection capability of the photovoltaic module.

[0031] First, refer to Figure 4 In this embodiment, the frame body 2 adopts a four-piece split interlocking splicing structure. The precise cooperation between the alignment groove 23 and the alignment block 24 allows adjacent frame bodies 2 to achieve seamless interlocking and docking, eliminating splicing gaps from the source. With the elastic limiting structure of the fixing block 8, the limiting post 11, and the spring 13, the initial fast locking at the splicing point is achieved. No precise calibration is required during installation, and rapid positioning and fixing can be completed, which greatly improves the on-site installation efficiency. Compared with the traditional bolt splicing frame, the installation speed is increased by several times, and the splicing accuracy is higher. There will be no misalignment or offset problems, laying the foundation for subsequent multiple locking.

[0032] Then, refer to Figure 6 In this embodiment, the fixing component 4 adopts a deep locking structure consisting of an L-shaped sliding groove 14, a vertical rod 17, a slider 19, and a threaded handle 22. By rotating the threaded handle 22, the vertical rod 17 can be inserted into the L-shaped sliding groove 14, achieving deep internal locking at the frame splicing point. This firmly fixes the fixing component 4 and the frame body 2 into one unit. The dual design of threaded self-locking and L-shaped limiting ensures a stable and reliable locking state. Even in environments with strong winds, blizzards, or long-term temperature variations, there will be no loosening or unlocking. This completely solves the core problem of low connection rigidity and easy loosening and misalignment at traditional frame splicing points, allowing the four frame bodies 2 to form a stable whole, simultaneously bearing force and resisting external loads.

[0033] Secondly, see Figure 2In this embodiment, the reinforcing component 3 adopts an integrated support structure of bottom mounting plate 25, connecting rod 26, and reinforcing rib 27, forming an all-round mesh reinforcement support from the bottom of the frame. This transforms the load on the frame from a single profile to the overall frame, significantly improving the frame's resistance to bending, torsion, and compression. It can effectively resist the multiple effects of strong outdoor wind loads, snow pressure, and temperature stress, preventing plastic deformation such as bending, twisting, and warping of the frame. At the same time, it provides bottom support for the solar panel 1, preventing the solar panel 1 from developing hidden cracks or damage due to uneven stress, thus providing all-round protection for the core components of the photovoltaic module.

[0034] Finally, see Figure 3 In this embodiment, the frame is equipped with a multi-protection structure consisting of rubber gasket 9 for sealing, top limit of stop bar 28, elastic limit locking, deep mechanical locking, and bottom reinforcement support. It is comprehensively optimized from four dimensions: splicing and fixing, structural strength, sealing protection, and limit fixing. All components are made of outdoor-specific corrosion-resistant, anti-aging, and high-strength materials, which are suitable for harsh outdoor environments such as open air, high temperature, low temperature, rain, snow, and sandstorms. Long-term use will not result in rust, deformation, loosening, or failure, perfectly meeting the long-term outdoor stable operation requirements of solar photovoltaic modules.

[0035] When using this anti-deformation solar photovoltaic aluminum frame, the frame body 2 is first assembled with the solar panel 1. The specific operation is as follows: four frame bodies 2 are arranged around the outer perimeter of the solar panel 1. The alignment block 24 of one frame body 2 is aligned with the alignment groove 23 of the adjacent frame body 2. The frame body 2 is gently pushed so that the alignment block 24 is fully inserted into the alignment groove 23, achieving precise interlocking and splicing of the adjacent frame bodies 2. After the four frame bodies 2 are spliced ​​in sequence, a complete outer frame is formed, which wraps around the four edges of the solar panel 1. At this time, the fixing blocks 8 at the top of the adjacent frame bodies 2 fit together, and the splicing gaps are completely eliminated, completing the initial splicing and positioning of the frame bodies 2.

[0036] Subsequently, the fixing component 4 is installed and the initial locking is completed. The specific operation is as follows: Align the vertical plate 6 at the bottom of the fixing plate 5 with the fixing block 8 at the top of the adjacent frame body 2, press the fixing plate 5 down, and the limiting posts 11 on both sides of the vertical plate 6 are squeezed by the fixing block 8 and slide into the vertical plate 6. At the same time, the baffle 12 compresses the spring 13. When the vertical plate 6 is completely attached to the fixing block 8, the limiting post 11 is precisely aligned with the limiting hole 10 on the fixing block 8. The spring 13 releases its elastic potential energy and pushes the baffle 12 and the limiting post 11 to slide outward, so that the limiting post 11 automatically inserts into the limiting hole 10, completing the elastic limiting locking of the vertical plate 6 and the fixing block 8. At this time, the fixing plate 5 covers the splicing gap, the vertical plate 6 is attached to both sides of the fixing block 8, and the rubber pad 9 fills the gap between the vertical plate 6 and the fixing block 8 to form a seal and buffer, completing the initial installation and locking of the fixing component 4.

[0037] Next, deep mechanical locking is completed to further improve the stability of the splicing. The specific operation is as follows: rotate the threaded handle 22 on the top of the fixed plate 5. The threaded handle 22 drives the horizontal plate 21 to move downward through the threaded transmission. The horizontal plate 21 drives the multiple vertical rods 17 at the bottom to slide downward simultaneously. The bottom of the vertical rods 17 contacts the inclined surface 20 of the slider 19, pushing the slider 19 to slide inward along the first slide groove 18. After the slider 19 slides, the vertical rods 17 are smoothly inserted into the L-shaped sliding groove 14 on the side of the frame body 2. When the vertical rods 17 are fully inserted into the bottom of the sliding groove 14, the L-shaped track forms a double limit on the vertical rods 17 in the horizontal and vertical directions, completely restricting the relative displacement between the vertical plate 6 and the frame body 2. The self-locking function of the threaded transmission keeps the horizontal plate 21 and the vertical rods 17 in a stable locked state, and there will be no reverse loosening. At this time, the adjacent frame bodies 2 form an inseparable and stable whole through the fixing component 4. The connection rigidity at the splicing point is maximized, and the problems of loosening, misalignment and deformation are completely eliminated.

[0038] Then, install the reinforcing component 3 to complete the bottom reinforcement support. The specific operation is as follows: fix the mounting plate 25 to the bottom of the frame body 2, so that the mounting plate 25 fits against the bottom surface of the solar panel 1 to provide bottom support for the solar panel 1. Then fix the connecting rod 26 between the mounting plates 25, so that the connecting rod 26 forms a bottom mesh support frame. Then fix multiple reinforcing ribs 27 evenly on the top of the connecting rod 26. The reinforcing ribs 27 extend upward to further strengthen the strength of the support structure. Finally, attach the stop bar 28 at the top of the frame body 2 to the top surface of the solar panel 1 to form a two-way clamping of the solar panel 1 from top to bottom, preventing the solar panel 1 from moving inside the frame. The stop bar 28 also serves as a top seal to prevent rainwater and dust from seeping in.

[0039] After assembly, the entire photovoltaic module is installed on the outdoor bracket and put into long-term power generation. During outdoor operation, the frame body 2 and the reinforcing component 3 work together to resist various external loads. When encountering strong winds, the lateral load generated by the strong wind is transferred through the frame body 2 to the bottom connecting rod 26 and reinforcing rib 27. The mesh support structure evenly distributes the lateral stress, preventing excessive local stress on the frame and causing bending or twisting. When covered by snow in winter, the vertical pressure of the snow is transferred through the solar panel 1 to the frame body 2 and the bottom reinforcing component 3. The vertical support structure of the reinforcing rib 27 and the connecting rod 26 resists the vertical pressure and prevents the frame from bending and deforming downwards. When the temperature changes due to nighttime or seasonal temperature variations, the frame body 2 undergoes thermal expansion and contraction deformation. The elastic structure of the rubber pad 9 adapts to these minor deformations. The elastic limiting structure of the limiting post 11 and the spring 13, along with the rigid structure of the threaded locking, work together to prevent the frame from deforming due to rigid compression and to prevent the splicing from loosening due to thermal expansion and contraction. At the same time, the multiple locking structure of the fixing component 4 always maintains a stable connection at the splice, preventing problems such as widening gaps, misalignment, and loosening. The protective frame-like frame body 2, the retaining rod 28, and the sealing structure of the rubber pad 9 prevent rainwater, wind, sand, and dust from entering the gap between the solar panel 1 and the frame, avoiding internal corrosion and dirt accumulation that could affect the performance of the component.

[0040] When maintenance or disassembly of the photovoltaic module is required, the specific operation is as follows: Rotate the threaded handle 22 on the top of the fixing plate 5 in the opposite direction. The threaded handle 22 drives the horizontal plate 21 to move upward. The horizontal plate 21 drives the vertical rod 17 to slide upward. The vertical rod 17 disengages from the L-shaped sliding groove 14. Under the elastic reset action, the slider 19 slides outward along the first sliding groove 18 to reset, completing the deep locking and unlocking. Then, press the limiting post 11 inward to disengage the limiting post 11 from the limiting hole 10 of the fixing block 8. At the same time, compress the spring 13 and pull the fixing plate 5 upward to remove the fixing component 4 from the frame body 2. Finally, separate the alignment blocks 24 and alignment grooves 23 of the four frame body 2 to remove the frame body 2 from the outside of the solar panel 1. The entire disassembly process does not require any tools, is simple and convenient to operate, and will not damage the frame body 2 and the solar panel 1, which facilitates later maintenance and component replacement.

[0041] During the long-term outdoor operation of solar photovoltaic modules, the multiple structural advantages of this anti-deformation aluminum frame continue to play a role. The fixed structure of split interlocking splicing, elastic limiting, and deep mechanical locking ensures that the splicing of the frame always maintains a seamless, stable, and high-rigidity connection, completely solving the problems of looseness, misalignment, and large gaps in traditional frame splicing. The reinforced support structure of bottom mounting plate 25, connecting rod 26, and reinforcing rib 27 greatly improves the frame's resistance to bending, torsion, and compression, fundamentally preventing plastic deformation such as bending, twisting, and warping of the frame. The protective structure of rubber gasket 9 sealing, stop bar 28 limiting, and elastic buffering improves the frame's sealing performance and resistance to vibration and temperature differences, protecting the solar panel 1 from external forces and environmental factors. All components are made of high-strength, corrosion-resistant, and anti-aging aluminum alloy and stainless steel, which are suitable for harsh outdoor environments. They are rust-free, deformation-free, and failure-free after long-term use, requiring no frequent maintenance or replacement.

[0042] This frame completely overcomes the industry pain points of traditional solar photovoltaic aluminum frames, such as single-profile splicing, lack of bottom reinforcement support, insufficient bending and torsional strength, low connection stiffness at splicing points, and easy deformation and loosening. It has been comprehensively optimized in four aspects: structural design, material selection, connection method, and support system. It not only meets the installation, protection, and load-bearing requirements of solar photovoltaic modules, but also significantly improves the frame's anti-deformation ability, structural strength, and outdoor durability. It effectively avoids problems such as solar panel microcracks, damage, and reduced power generation efficiency caused by frame deformation, significantly extends the overall service life of solar photovoltaic modules, reduces outdoor operation and maintenance costs, and perfectly adapts to the usage needs of various solar photovoltaic power stations such as industrial, commercial, and residential applications. It is the ideal protective and load-bearing frame for outdoor solar photovoltaic modules.
