Description

Technical Field

[0001] This invention relates to the field of frame technology, specifically to a lightweight solar module frame. Background Technology

[0002] The frame of a solar module is a structural protective frame around the solar panel. It is mainly used to fix, support and protect the internal cells, glass cover and encapsulation materials. It also undertakes the functions of installation, grounding and electrical safety. It is an indispensable part of the module and directly affects the mechanical strength, weather resistance and service life of the module.

[0003] Currently, the Northwest region, as the core area for photovoltaic power generation in my country, has vast Gobi Desert, barren land, and mountainous areas. It has built many large-scale ground-mounted solar power plants. However, due to the challenges of strong winds, sandstorms, snow accumulation, and large temperature differences between day and night, the requirements for the wind pressure resistance and durability of the frame are extremely high. Aluminum alloy frames are the main material. Although they are lightweight and easy to process, making them suitable for large-scale installations in the Northwest region, the long-term exposure to strong winds can easily cause slight deformation of the module frame array. When the frame is slightly bent or twisted by external forces, the mechanical stress generated will be transmitted to the solar cells through the encapsulation material. Since the solar cells are brittle, local stress concentration can easily lead to microcracks, causing microcracks in the solar cells and power generation failures, thus affecting the normal use of solar photovoltaic panels.

[0004] Therefore, we propose a lightweight solar module frame to address the problems mentioned above. Summary of the Invention

[0007] Preferably, the reinforcing component further includes a solid base area, the outer surface of which is fixedly connected to one side of the outer surface of the transverse partition bar, the outer surface of the reinforcing plate is fixedly connected to the other side of the outer surface of the transverse partition bar, and multiple X-shaped cross ribs are fixed to the inner walls of both reinforcing plates.

[0008] Preferably, the inner walls of the two solid substrate areas are provided with porous lightweight hollow areas, and multiple triangular reinforcing ribs are symmetrically fixed between the outer surfaces of the two solid substrate areas. The reinforcing plate, the transverse partition ribs and the solid substrate areas are all made of aluminum alloy.

[0009] Preferably, one end of the first spring is fixedly connected to the inner wall of one of the solid base areas, and the other end of the first spring is fixedly connected to the outer surface of the lower hinge plate, which faces the hollow area.

[0010] Preferably, the elastic connection assembly further includes a connector, the rubber ring is fixed inside the connector, and a connector is also provided inside the connector, the connector being disposed on the inner wall of the rubber ring.

[0011] Preferably, the sliding buffer mechanism further includes two support frames, each with a rubber buffer seat on its top. The top of the rubber buffer seat is fixedly connected to the outer surface of the solid base area, and the outer surfaces of the two support frames are respectively fixedly connected to the outer surfaces of the two sides of the limiting frame.

[0012] Preferably, a connecting shaft is fixedly embedded between the relative inner walls of the limiting frame, the outer surface of the slider and the outer surface of the opposite solid base area are fixedly connected, and the slider is movably sleeved on the outer surface of the connecting shaft.

[0013] Preferably, one end of each of the two second springs is fixedly connected to the outer surfaces of the two sides of the slider, and the other end of each of the two second springs is fixedly connected to the inner walls of the limiting frame. Both of the two second springs are sleeved on the outer surface of the connecting shaft.

[0014] Preferably, the solar photovoltaic panel includes a battery panel, and both outer surfaces of the battery panel are provided with a special solar photovoltaic encapsulation film. One of the special solar photovoltaic encapsulation films is provided with a back plate on its outer surface, and the other special solar photovoltaic encapsulation film is provided with tempered glass on its outer surface.

[0015] Preferably, all four reinforcing components are fixedly connected to the outer surface of the solar photovoltaic panel, one inner wall of the connector is fixedly connected to the outer surface of the back plate, and the other inner wall of the connector is fixedly connected to the outer surface of the tempered glass.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the Northwest region, to ensure the stability of the lightweight frame in the face of wind and snow, a large amount of snow and sand falls onto the surface of the lower hinge plate, causing the lower hinge plate to rotate downwards along the first spring and detach from the frame, thus achieving automatic cleaning of snow and sand. By setting rubber rings at the joints of each frame, the deformation of the rubber rings absorbs the impact force generated by external loads, reducing stress concentration in specific areas of the frame and compensating for the lack of rigidity of lightweight materials. When strong winds easily exert lifting or lateral thrust on the photovoltaic panels, the two second springs, the first buffer pad, and the second buffer pad provide a buffering effect on the frame, solving the problem that the low strength of the lightweight solar module frame itself makes it difficult to ensure the stability of solar panels installed in the Northwest region.

[0018] 2. To maintain its stability, the strength of the reinforcing plate and its resistance to cyclic loads are improved through the action of multiple X-shaped cross stiffeners. This effectively disperses and transmits shear force, reducing stress concentration. The design of the porous lightweight hollow area prevents stress concentration in the frame, overcomes the drawback of stress concentration on the same vertical plane, suppresses unilateral local collapse and frame torsion deformation, and significantly optimizes torsional and bending stability.

[0019] 3. To ensure the stability and lightweight of the frame, staggered triangular reinforcing ribs are used to ensure the stability of the connection between the two, thereby ensuring the stability and strength of each frame. By setting the left and right staggered triangular reinforcing ribs, not only are materials saved and the self-weight of the frame reduced, but the stress support points of the triangular reinforcing ribs are not on the same cross section, which breaks the drawback of stress concentration on the same vertical plane, suppresses unilateral local collapse and frame torsion deformation, and significantly optimizes torsional and bending stability.

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-8 The present invention provides a technical solution: a lightweight solar module frame, including a solar photovoltaic panel 1. Four reinforcing components 2 are disposed on the outer surface of the solar photovoltaic panel 1. Each reinforcing component 2 includes two reinforcing plates 201 and two transverse partition ribs 203. A hollow area 207 is disposed between the outer surfaces of the two reinforcing plates 201. Multiple upper hinge plates 208 are fixed to the bottom of one of the transverse partition ribs 203. A hinge rotation spindle 210 is fixedly embedded in the inner wall of the upper hinge plate 208. A lower hinge plate 209 is movably sleeved on the outer surface of the hinge rotation spindle 210. A first spring 2 is disposed at the bottom of the lower hinge plate 209. 11. An elastic connecting component 3 is provided between the outer surfaces of each pair of adjacent reinforcing components 2. The elastic connecting component 3 includes a rubber ring 302 for buffering the connection between the two adjacent reinforcing components 2, and a sliding buffer mechanism 4. The sliding buffer mechanism 4 includes a slider 405 and a limiting frame 403. The outer surfaces of both sides of the slider 405 are provided with a second spring 406 for dynamically moving the frame within a certain range. The inner top surface of the limiting frame 403 is provided with a first buffer pad 407 for buffering the upward rotation of the frame, and the inner bottom surface of the limiting frame 403 is provided with a second buffer pad 408 for buffering the downward rotation of the frame.

[0032] The reinforcing plate 201 adopts a hollow design, achieving the goal of lightweighting the solar panel frame. While ensuring mechanical strength, it reduces the amount of aluminum alloy used, thus achieving weight reduction. The transverse partition rib 203 acts as a bridge connecting the reinforcing plate 201 and the solid base area 204. Its thickness enhances the bending and torsional strength of the frame section, reducing pressure-induced indentation deformation. Furthermore, by setting a hollow area 207 between the two reinforcing plates 201, material consumption is reduced, and it also facilitates automatic rain and snow removal when dealing with northwest winds, snow, and sandstorms. When rain and snow accumulate on the frame surface, such as... Figure 2 As shown, the edges and corners of the reinforcing plate 201 are all designed with arc surfaces, making it difficult for rain and snow to remain on its surface. Each upper hinged plate 208 is set between the outer surfaces of two adjacent triangular reinforcing ribs 206. When rain and snow are retained in the hollow area 207, since the depth of the triangular reinforcing ribs 206 is much smaller than the length of the lower hinged plate 209, a large amount of snow and sand falls onto the surface of the lower hinged plate 209. When the weight of the snow and sand reaches a certain weight, the weight of the lower hinged plate 209 is greater than the elastic force of the first spring 211, causing the lower hinged plate 209 to rotate downward along the first spring 211. This causes the snow and sand retained on its surface to slide outward along the surface of the lower hinged plate 209 and detach from the lower hinged plate 209, thus achieving automatic cleaning of snow and sand and preventing external snow and sand from remaining on its surface and increasing its own load.

[0033] Since the solar module frame has four sides, the traditional four-sided frame is mostly rigidly connected, which is prone to stress concentration. By setting a rubber ring 302 at the connection of each two adjacent sides, the deformation of the rubber ring 302 itself absorbs the impact force generated by the external load, reducing the concentration of stress in specific areas of the frame and making up for the problem of insufficient rigidity of lightweight materials.

[0034] Due to the open terrain of Northwest China, characterized by mountains and deserts, strong winds can easily exert lifting or lateral thrust on the frame. The two second springs 406 allow the slider 405 to move the entire frame a certain distance along the surface of the connecting shaft 404 under the influence of external wind force, and then limit its movement under the action of the two second springs 406. Simultaneously, the two second springs 406 can also absorb the intensity of the lateral thrust on the frame through their own elasticity, providing a buffering effect. Furthermore, it allows the frame to rotate a certain angle along the surface of the connecting shaft 404 within a certain range under the influence of external wind force, both clockwise and counterclockwise. The angles are respectively matched with the distances between the first buffer pad 407 and the second buffer pad 408. When the slider 405 drives the frame to rotate to the position where it contacts the first buffer pad 407 or the second buffer pad 408, it will be driven to reverse and reset under the elastic force of the buffer pad itself. By absorbing the instantaneous impact energy through compression-rebound deformation, the concentrated stress is converted into uniformly distributed elastic strain energy, extending the life of the frame. In this way, the stability and wind and snow resistance of the solar frame are guaranteed from multiple aspects, solving the problem that the low strength of the lightweight solar module frame itself makes it difficult to ensure the stability of the solar panel installed in the Northwest region.

[0035] It should also be noted that the reinforcing component 2 also includes a solid base area 204. The outer surface of the solid base area 204 is fixedly connected to one side of the outer surface of the transverse partition rib 203, and the outer surface of the reinforcing plate 201 is fixedly connected to the other side of the outer surface of the transverse partition rib 203. Multiple X-shaped cross ribs 202 are fixed to the inner walls of both reinforcing plates 201.

[0036] like Figures 1-3 As shown, the solid base area 204 has a longer side to increase the heat dissipation area of ​​the frame and dissipate the heat accumulated at the edge of the component. Since the reinforcing plate 201 is hollow, in order to maintain its stability, the strength of the reinforcing plate 201 and its resistance to cyclic loads can be improved through the action of multiple X-shaped cross stiffeners 202, effectively dispersing and transferring shear force and reducing the occurrence of stress concentration.

[0037] It should also be noted that the inner walls of the two solid base areas 204 are provided with porous lightweight hollow areas 205, and multiple triangular reinforcing ribs 206 are symmetrically fixed between the outer surfaces of the two solid base areas 204. The reinforcing plate 201, the transverse partition rib 203 and the solid base area 204 are all made of aluminum alloy.

[0038] like Figures 1-3As shown, the porous lightweight hollow area 205 prevents stress concentration in the frame. When the frame is subjected to wind pressure or external object pressure, resulting in a high self-weight, the pores in the porous lightweight hollow area 205 can disperse the thin-wall tensile stress, preventing large-area bulging and instability of the frame sidewalls. This achieves the purpose of balancing stress and reducing single-point stress overload. To achieve the lightweight design of the frame, it is made of aluminum alloy. Furthermore, to achieve the connection between the two solid base areas 204 and ensure stability and lightness... The quality is enhanced by the staggered triangular reinforcing ribs 206, which ensure the stability of the connection between the two, thereby ensuring the stability and strength of each frame. The staggered triangular reinforcing ribs 206 not only save materials and reduce the self-weight of the frame, but also ensure that the stress support points of the triangular reinforcing ribs 206 are not on the same cross section. The bending load caused by wind, snow and component self-weight is transferred in layers along the hypotenuses of the triangles at different heights and positions, breaking the drawback of stress concentration on the same vertical plane, suppressing unilateral local collapse and frame torsion deformation, and significantly optimizing torsional and bending stability.

[0039] It should also be noted that one end of the first spring 211 is fixedly connected to the inner wall of one of the solid base areas 204, and the other end of the first spring 211 is fixedly connected to the outer surface of the lower hinge plate 209, which is directly opposite the hollow area 207.

[0040] like Figures 1-3 As shown, the first spring 211 is fixed to the lower hinge plate 209 so that it can be reset under the elastic action of the first spring 211 after being tilted by force. In order to ensure that the snow and mud falling to the hollow area 207 accurately fall onto the lower hinge plate 209, the top view of the lower hinge plate 209 coincides with the top view of the hollow area 207.

[0041] It should also be noted that the elastic connection component 3 also includes a connector 301, a rubber ring 302 fixed inside the connector 301, and a connector 303 is also provided inside the connector 301, which is located on the inner wall of the rubber ring 302.

[0042] like Figure 1 and Figure 5 As shown, during the connection of the four frames, the two ends of each frame are inserted into the connectors 303 in the two connectors 301 corresponding to them. Then, the two ends of the frame can be fixed in the two connectors 303 opposite to them by external welding equipment. When the connection is subjected to external stress, the impact force generated by the external load is absorbed by the deformation of the rubber ring 302 itself.

[0043] It should also be noted that the sliding buffer mechanism 4 also includes two support frames 401. Each of the two support frames 401 is provided with a rubber buffer seat 402 on its top. The top of the rubber buffer seat 402 is fixedly connected to the outer surface of the solid base area 204. The outer surfaces of the two support frames 401 are respectively fixedly connected to the outer surfaces of the two sides of the limiting frame 403.

[0044] like Figure 1 and Figures 6-8 As shown, the two rubber buffer seats 402 allow the frame to undergo a certain displacement within the deformation range of the rubber buffer seats 402 when subjected to lateral wind force and lifting force. In addition, the rubber buffer seats 402 can also buffer the impact of external forces on the frame. The two support frames 401 and the limiting frame 403 together form the fixed base of the solar module.

[0045] It should also be noted that a connecting shaft 404 is fixedly embedded between the relative inner walls of the limiting frame 403, the outer surface of the slider 405 is fixedly connected to the outer surface of the solid base area 204 opposite to it, and the slider 405 is movably sleeved on the outer surface of the connecting shaft 404.

[0046] like Figure 1 and Figures 6-8 As shown, the connecting shaft 404 supports the slider 405, allowing it to move a certain distance left, right, up, and down along its surface.

[0047] It should also be noted that one end of each of the two second springs 406 is fixedly connected to the outer surfaces of both sides of the slider 405, and the other end of each of the two second springs 406 is fixedly connected to the inner walls of the limit frame 403. Both of the two second springs 406 are sleeved on the outer surface of the connecting shaft 404.

[0048] like Figure 1 and Figures 6-8 As shown, by sleeved on the surface of the connecting shaft 404, the second spring 406 is limited. In addition, the stability is ensured by fixing the second spring 406 to the slider 405 and the limiting frame 403.

[0049] It should also be noted that the solar photovoltaic panel 1 includes a battery panel 101. Both outer surfaces of the battery panel 101 are provided with a solar photovoltaic encapsulation film 102. One of the solar photovoltaic encapsulation films 102 has a back plate 103 on its outer surface, and the other solar photovoltaic encapsulation film 102 has tempered glass 104 on its outer surface.

[0050] like Figure 1 and Figure 5As shown, the solar photovoltaic encapsulation film 102 disposed on both sides of the solar panel 101 plays a role in wrapping and protecting the solar panel 101. The solar photovoltaic encapsulation film 102 is made of ethylene-vinyl acetate copolymer and realizes the connection between the solar panel 101, the tempered glass 104 and the back sheet 103. In addition, the tempered glass 104 has high light transmittance, allowing more sunlight to reach the solar panel 101. The back sheet 103 provides safety insulation on the back of the module to prevent electric shock.

[0051] It should also be noted that all four reinforcing components 2 are fixedly connected to the outer surface of the solar photovoltaic panel 1, one side inner wall of the connector 301 is fixedly connected to the outer surface of the back plate 103, and the other side inner wall of the connector 301 is fixedly connected to the outer surface of the tempered glass 104.

[0052] like Figures 1-6 As shown, the four reinforcing components 2 represent the four frames of the solar module. The connection between the four frames and the solar photovoltaic panel 1 provides fixation and protection for the solar photovoltaic panel 1. The connection between the connector 301 and the tempered glass 104 and the back panel 103 ensures the stability of the connector 301.

[0053] The usage and working principle of this device are as follows: To further enhance the stability of the solar module frame, the reinforcing plate 201 adopts a hollow design, with multiple X-shaped cross ribs 202 inside. These ribs disperse and transfer the shear force on the frame, reducing stress concentration. The transverse partition ribs 203 act as a bridge connecting the reinforcing plate 201 and the solid base area 204. Their thickness reduces the deformation of the frame under pressure. The interior is designed with porous, lightweight hollow areas 205, which disperse the thin-wall tensile stress when the frame is subjected to wind pressure or external object pressure, resulting in a high self-weight. The staggered triangular reinforcing ribs 206 ensure that their stress points are not on the same cross section, mitigating the effects of wind, snow, and other factors on the module. The bending load caused by its own weight is transferred layer by layer along the hypotenuses of the triangles at different heights and positions, breaking the drawback of stress concentration on the same vertical plane and suppressing unilateral local collapse and frame torsion deformation. When rain and snow remain on the frame surface, because the depth of the triangular reinforcing ribs 206 is much smaller than the length of the lower hinge plate 209, a large amount of snow and sand falls onto the surface of the lower hinge plate 209. When the weight of the snow and sand reaches a certain level, the weight of the lower hinge plate 209 itself exceeds the elastic force of the first spring 211, causing the lower hinge plate 209 to rotate downwards along the first spring 211. This causes the snow and sand remaining on its surface to slide outwards along the surface of the lower hinge plate 209 and detach from the lower hinge plate 209. During the process, each end of the frame is inserted into the connector 303 in its corresponding connector 301 for welding and fixation. When the connection is subjected to external stress, the rubber ring 302 absorbs the impact force generated by the external load through its own deformation, reducing the concentration of stress in specific areas of the frame. Due to the open terrain of Northwest China, with its alternating mountains and deserts, strong winds can easily generate periodic lifting or lateral thrust on the photovoltaic array. Through the action of the two second springs 406, the slider 405 can move the entire frame a certain distance along the surface of the connecting shaft 404 under the action of external wind force, and is limited by the action of the two second springs 406. At the same time, the two second springs 406 can also exert their own elastic force. The design eliminates the lateral thrust on the frame, providing a buffering effect. Simultaneously, it allows the frame to rotate a certain angle along the surface of the connecting shaft 404 within a certain range under external wind force. The clockwise and counterclockwise rotation angles are matched to the distances between the first buffer pad 407 and the second buffer pad 408, respectively. When the slider 405 rotates the frame to a position where it contacts the first buffer pad 407 or the second buffer pad 408, it will be driven to return to its original position under the elastic force of the buffer pad itself. This compression-rebound deformation absorbs instantaneous impact energy, converting concentrated stress into uniformly distributed elastic strain energy, extending the frame's lifespan. This is particularly suitable for areas with high wind loads, thus ensuring the stability and wind and snow resistance of the solar frame from multiple perspectives.To address the issue of strong winds in Northwest China easily generating periodic lifting or lateral thrust on photovoltaic arrays, two second springs 406 allow the slider 405 to move the entire frame a certain distance along the surface of the connecting shaft 404 under the influence of external wind force. Simultaneously, the two second springs 406 can also absorb the intensity of lateral thrust on the frame through their own elasticity, providing a buffering effect. This allows the frame to rotate a certain angle along the surface of the connecting shaft 404 within a certain range under the influence of external wind force. When the slider 405 rotates the frame to a position where it contacts the first buffer pad 407 or the second buffer pad 408, it will be driven to reverse and reset under the elasticity of the buffer pad itself. This compression-rebound deformation absorbs instantaneous impact energy, converting concentrated stress into uniformly distributed elastic strain energy, extending the frame's lifespan, and is particularly suitable for high-wind-load areas in Northwest China.
