Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically providing a clamp for photovoltaic modules. Background Technology

[0002] A-side frameless photovoltaic modules are those where the A-side is frameless. The frame and laminate are bonded using silicone or structural adhesive. During the initial curing stages of the silicone and structural adhesive, they cannot immediately form a tight bond with the laminate, and the curing time for silicone is relatively long. During this period, the laminate is highly susceptible to detachment from the frame. This not only affects the overall structural stability of the photovoltaic module but may also lead to defects in subsequent encapsulation processes, and in severe cases, even render the module unusable, significantly impacting production efficiency and product quality. Therefore, clamps are needed to hold and fix the laminate to the frame to prevent detachment.

[0003] Existing fixtures, after clamping and fixing the laminate to the frame, are prone to deformation due to clamping force, causing the fixtures to detach from the photovoltaic modules. This makes it impossible to continuously and stably fix the modules, seriously affecting the continuity and stability of production, and restricting the production efficiency and quality improvement of photovoltaic modules.

[0004] Accordingly, there is a need in the art for a new fixture for photovoltaic modules to address the aforementioned problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problem, namely, how to prevent the fixture from deforming and detaching from the photovoltaic module.

[0006] This utility model provides a clamp for photovoltaic modules, the clamp comprising: a first clamping structure and a second clamping structure; a support connected to the first clamping structure and located between the first clamping structure and the second clamping structure, the second clamping structure being movably connected to the support, the first clamping structure, the second clamping structure, and the support forming an open clamping groove for placing the photovoltaic module; and an elastic member, both ends of which are connected to the second clamping structure and the support respectively, and configured to provide elastic force to the second clamping structure to force the second clamping structure to move and clamp the photovoltaic module with the first clamping structure.

[0007] When using the above technical solution, during clamp installation, pulling the second clamping structure away from the first clamping structure increases the space of the clamping groove, facilitating the installation of the clamp onto the photovoltaic module. After the clamp is installed in place, the support fits against the side of the photovoltaic module. The second clamping structure is then released, and under the elastic force of the elastic element, it moves and clamps the photovoltaic module together with the first clamping structure. Simultaneously, the second clamping structure and the support are connected via an elastic element rather than a rigid connection, preventing deformation of the clamping groove from causing the clamp to detach from the photovoltaic module. In summary, the clamp of this invention can conveniently clamp the photovoltaic module while preventing deformation and detachment, achieving continuous and stable clamping and fixing of the photovoltaic module.

[0008] In the specific embodiment of the above-described clamp for photovoltaic modules, the second clamping structure is provided with a stop block. The stop block is configured to clamp the first side of the frame of the photovoltaic module between the stop block and the support, and to make the second side of the frame perpendicular to the first side abut against the support.

[0009] When the above technical solution is adopted, since the frame of a photovoltaic module without an A-side is usually composed of a first side and a second side that are perpendicular to each other, the first side and the second side are prone to deformation, which can cause the size of the photovoltaic module to expand or shrink, affecting the quality of the photovoltaic module and its compatibility with other components. Therefore, by clamping the first side of the frame between the block and the support, and abutting the second side of the frame against the support, the frame can be limited, preventing the frame from deforming and causing the size of the photovoltaic module to expand or shrink, thereby avoiding affecting the product quality of the photovoltaic module.

[0010] In the specific embodiment of the above-mentioned clamp for photovoltaic modules, a buffer structure is provided in the clamping groove. The buffer structure is located at the connection between the support and the first clamping structure. The buffer structure is configured to be embedded in the gap between the laminate of the photovoltaic module and the second surface.

[0011] When the above technical solution is adopted, since there is a gap between the laminate and the second side, stress concentration is likely to occur at the gap when the first side of the frame is clamped between the stop and the support after the fixture and photovoltaic module are installed. By setting a buffer structure, the buffer structure is embedded in the gap to fill the gap, which can absorb and disperse the stress at this point, effectively avoid deformation at this point, and thus avoid affecting the product quality.

[0012] In the specific embodiment of the clamp for photovoltaic modules described above, the stop is made of an elastic material.

[0013] When the above technical solution is adopted, the block can act as a buffer when it comes into contact with the frame, thus avoiding damage to the frame.

[0014] In the specific embodiment of the above-described clamp for photovoltaic modules, the stop block is bolted or snapped into the second clamping structure.

[0015] By adopting the above technical solution, it can be ensured that the stop block is not easy to loosen or fall off during the use of the clamp, and at the same time, it is convenient to install and remove the stop block.

[0016] In the specific embodiment of the above-mentioned clamp for photovoltaic modules, the clamp further includes a set screw, and the support is provided with a threaded hole. The set screw is threadedly connected to the threaded hole and abuts against the second clamping structure.

[0017] By adopting the above technical solution, the relative position of the set screw and the support can be adjusted by rotating the set screw, thereby adjusting the distance between the second clamping structure that abuts against the set screw and the support. This ensures that the clamp can hold photovoltaic modules of different thicknesses when installing the clamp, thereby improving the applicability of the clamp.

[0018] In the specific embodiment of the above-described clamp for photovoltaic modules, the number of set screws is set to at least two, and the at least two set screws are symmetrically arranged along the length direction of the second clamping structure.

[0019] By adopting the above technical solution, it can be ensured that the distance between the second clamping structure and the support is the same at all points along the length of the second clamping structure, thereby achieving precise clamping of the photovoltaic module.

[0020] In the specific embodiment of the above-mentioned clamp for photovoltaic modules, the support is further provided with a mounting hole, which is coaxial with the threaded hole and extends toward and through the first clamping structure.

[0021] When the above technical solution is adopted, if it is necessary to rotate the set screw, simply insert the wrench into the mounting hole to rotate the set screw. The operation is simple and convenient.

[0022] In the specific embodiment of the above-mentioned clamp for photovoltaic modules, the support is provided with a guide hole, and the clamp further includes a guide post, which is fixedly connected to the second clamping structure and movably connected to the guide hole.

[0023] When the above technical solution is adopted, the guide post and the guide hole are movably connected, which can provide guidance for the movement of the guide post, and thus provide guidance for the movement of the second clamping structure relative to the first clamping structure, so as to avoid deformation of the frame and photovoltaic module due to the deformation of the clamp.

[0024] In the specific embodiment of the above-mentioned clamp for photovoltaic modules, the guide hole includes a first hole segment and a second hole segment, the diameter of the first hole segment is larger than the diameter of the second hole segment, and a stepped surface is formed between the first hole segment and the second hole segment; the first end of the guide post has a retaining ring, the retaining ring is located inside the first hole segment, the second end of the guide post is connected to the second clamping structure, and the elastic element is sleeved on the outside of the guide post and connected between the stepped surface and the retaining ring.

[0025] When the above technical solution is adopted, the elastic element is connected between the stepped surface and the retaining ring, so that the elastic element can provide elastic force for the second clamping structure; at the same time, by sleeve the elastic element outside the guide post, the elastic element can be prevented from bending laterally when stretched or compressed, ensuring the stability of the elastic element and effectively improving the service life of the elastic element.

[0026] In the specific embodiment of the above-described clamp for photovoltaic modules, the number of elastic elements is set to at least two, and the at least two elastic elements are arranged symmetrically along the length direction of the second clamping structure.

[0027] When the above technical solution is adopted, at least two elastic elements arranged symmetrically can provide a uniform clamping force along the length of the second clamping structure, ensuring that the clamp can stably clamp the photovoltaic module and avoid stress concentration from damaging the photovoltaic module.

[0028] In the specific embodiment of the clamp for photovoltaic modules described above, the elastic element is configured as a spring.

[0029] When the above technical solution is adopted, the spring can provide the second clamping structure with an elastic force to move towards the first clamping structure in order to clamp the photovoltaic module. Moreover, the spring has low cost, small space occupation, and high energy conversion efficiency, which can meet the design and usage requirements.

[0030] In the specific embodiment of the fixture for photovoltaic modules described above, the photovoltaic module is a frameless photovoltaic module without an A-side frame.

[0031] When the above technical solution is adopted, since the A side of the frameless photovoltaic module is frameless, the laminate is more likely to detach from the frame. Therefore, by using a clamp to hold and fix the laminate to the frame, the detachment of the frame from the laminate can be effectively prevented.

[0032] Compared to existing technologies, the advantages of the clamp for photovoltaic modules provided by this invention are as follows: When installing the clamp, pulling the second clamping structure away from the first clamping structure increases the space of the clamping groove, facilitating the installation of the clamp onto the photovoltaic module. After the clamp is installed in place, the support fits against the side of the photovoltaic module. Releasing the second clamping structure allows it to move under the elastic force of the elastic element and clamp the photovoltaic module together with the first clamping structure. Simultaneously, the second clamping structure is connected to the support via an elastic element rather than a rigid connection, preventing deformation of the clamping groove from causing the clamp to detach from the photovoltaic module. In summary, the clamp of this invention can conveniently clamp the photovoltaic module while preventing deformation and detachment, achieving continuous and stable clamping and fixing of the photovoltaic module.

Detailed Implementation

[0040] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0041] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0042] Furthermore, it should be noted that in the description of this utility model, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In addition, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] See Figures 1-4 This utility model provides a clamp for a photovoltaic module 9. The clamp includes a first clamping structure 1, a second clamping structure 2, a support 3, and an elastic member 4. The support 3 is connected to the first clamping structure 1 and is located between the first clamping structure 1 and the second clamping structure 2. The second clamping structure 2 is movably connected to the support 3. The first clamping structure 1, the second clamping structure 2, and the support 3 form an open clamping groove for placing the photovoltaic module 9. The two ends of the elastic member 4 are respectively connected to the second clamping structure 2 and the support 3, and are configured to provide elastic force to the second clamping structure 2 to force the second clamping structure 2 to move and clamp the photovoltaic module 9 with the first clamping structure 1. Based on the above structural design, when installing the clamp, pulling the second clamping structure 1 away from the first clamping structure 2 increases the space of the clamping groove, facilitating the installation of the clamp onto the photovoltaic module 9. After the clamp is installed in place, the support 3 fits against the side of the photovoltaic module 9. The second clamping structure 2 is then released, and under the elastic force of the elastic element 4, it moves and clamps the photovoltaic module 9 together with the first clamping structure 1. Simultaneously, the second clamping structure 2 and the support 3 are connected by the elastic element 4 rather than a rigid connection, which avoids deformation of the rigid connection that could enlarge the opening of the clamping groove and cause the clamp to detach from the photovoltaic module 9. In summary, the clamp of this invention can conveniently clamp the photovoltaic module 9 while preventing deformation and detachment, thus achieving continuous and stable clamping and fixing of the photovoltaic module 9.

[0044] Among them, photovoltaic module 9 can be a photovoltaic module without A-side or other suitable types.

[0045] It should be noted that the support 3 and the first clamping structure 1 can be fixedly connected by welding, welding or bolting, or they can be integrally formed. Those skilled in the art can make adjustments as needed.

[0046] like Figures 1-3 As shown, in one or more embodiments, the second clamping structure 2 is provided with a stop block 5. The stop block 5 is configured to clamp the first side of the frame 91 of the photovoltaic module 9 between the stop block 5 and the support 3, and to make the second side of the frame 91, which is perpendicular to the first side, abut against the support 3. Based on the above structural configuration, since the frame 91 of the photovoltaic module 9 without A side is usually composed of a first side and a second side that are perpendicular to each other, the first side and the second side are prone to deformation, which can cause the external dimensions of the photovoltaic module 9 to expand or shrink, affecting the quality of the photovoltaic module 9 and its compatibility with other components. Therefore, by clamping the first side of the frame 91 between the stop block 5 and the support 3, and making the second side of the frame 91 abut against the support 3, the frame 91 can be limited, preventing the frame 91 from deforming and causing the external dimensions of the photovoltaic module 9 to expand or shrink, thereby avoiding affecting the product quality of the photovoltaic module 9.

[0047] In this context, the second side of the frame 91 of the photovoltaic module 9 refers to the side of the frame 91 arranged along the thickness direction of the photovoltaic module 9, and the first side of the frame 91 refers to the side perpendicular to the second side and away from the laminate 92. Figure 2 The top surface of the border 91 shown.

[0048] It should be noted that the number of stops 5 can be one, and the stops 5 can penetrate the second clamping structure 2 along the length direction of the second clamping structure 2; the number of stops 5 can also be multiple, and multiple stops 5 can be arranged at equal intervals along the length direction of the second clamping structure 2.

[0049] Possibly, the thickness of the stop block 5 can be greater than the thickness of the first surface of the frame 91, so that the stop block 5 can better prevent the frame 91 from deforming. Understandably, the thickness of the stop block 5 can also be other suitable thicknesses, as long as it can clamp the first surface of the frame 91 of the photovoltaic module 9 between the stop block 5 and the support 3.

[0050] Optionally, the stop block 5 is made of an elastic material. Based on the above structural design, the stop block 5 can act as a buffer when it comes into contact with the frame 91, thus preventing damage to the frame 91.

[0051] Specifically, the elastic material used for the stop block 5 can be engineering plastic, rubber, or other suitable flexible materials, as long as it can limit the frame 91 while also providing a buffering effect to avoid damage to the frame 91.

[0052] Optionally, the stop block 5 is bolted or snapped to the second clamping structure 2. Based on the above structural design, it can be ensured that the stop block 5 is not easy to loosen or fall off during the use of the clamp, while also facilitating the installation and removal of the stop block 5.

[0053] It should be noted that the stop block 5 and the second clamping structure 2 can also be connected by bonding or injection molding processes, as long as the stop block 5 can be fixedly connected to the second clamping structure 2 to ensure that the stop block 5 is not easy to loosen or fall off during the use of the clamp.

[0054] Furthermore, a buffer structure 6 is provided within the clamping groove. The buffer structure 6 is located at the connection between the support 3 and the first clamping structure 1. The buffer structure 6 is configured to be embedded in the gap 93 between the laminate 92 and the second surface of the photovoltaic module 9. Based on the above structural configuration, since there is a gap 93 between the laminate 92 and the second surface, stress concentration is likely to occur at the gap 93 when the first surface of the frame 91 is clamped between the stop block 5 and the support 3 after the clamp and the photovoltaic module 9 are installed. By providing the buffer structure 6, which is embedded in the gap 93 and fills the gap 93, the stress at this location can be absorbed and dispersed, effectively preventing deformation and thus avoiding affecting product quality.

[0055] It should be noted that the cushioning structure 6 can be made of rigid polyurethane sponge or rubber sponge, or other elastic materials with high hardness. Those skilled in the art can make adjustments as needed.

[0056] like Figures 1-4 As shown, in one or more embodiments, the clamp further includes a set screw 7, and the support 3 is provided with a threaded hole 31. The set screw 7 is threadedly connected to the threaded hole 31 and abuts against the second clamping structure 2. Based on the above structural configuration, by rotating the set screw 7, the relative position of the set screw 7 and the support 3 can be adjusted, thereby adjusting the distance between the second clamping structure 2 abutting against the set screw 7 and the support 3. This ensures that the clamp can hold the photovoltaic module 9 when it is installed with photovoltaic modules 9 of different thicknesses, thereby improving the applicability of the clamp.

[0057] It should be noted that the set screw 7 can be an internal hexagonal set screw 7 or a slotted set screw 7, or other types of set screw 7, without being specifically limited here.

[0058] Optionally, the number of set screws 7 is set to at least two, and the at least two set screws 7 are symmetrically arranged along the length direction of the second clamping structure 2. Based on the above structural arrangement, it can be ensured that the distance between the second clamping structure 2 and the support 3 is the same at all points along the length direction of the second clamping structure 2, thereby achieving precise clamping of the photovoltaic module 9.

[0059] Optionally, the support 3 is also provided with a mounting hole 32, which is coaxial with the threaded hole 31. The mounting hole 32 extends toward and through the first clamping structure 1. Based on the above structural configuration, when it is necessary to rotate the set screw 7, a wrench can be inserted into the mounting hole 32 to rotate the set screw 7, which is simple and convenient to operate.

[0060] like Figure 1 and Figure 4 As shown, in one or more embodiments, the support 3 is provided with a guide hole 33, and the clamp also includes a guide post 8. The guide post 8 is fixedly connected to the second clamping structure 2 and movably connected to the guide hole 33. Based on the above structural configuration, the movable connection between the guide post 8 and the guide hole 33 can provide guidance for the movement of the guide post 8, thereby providing guidance for the movement of the second clamping structure 2 relative to the first clamping structure 1, and avoiding deformation of the frame 91 and the photovoltaic module 9 due to clamp deformation.

[0061] It should be noted that the guide post 8 and the second clamping structure 2 can be connected by welding, bonding, or bolting, as long as a fixed connection is possible. When the guide post 8 and the second clamping structure 2 are welded together, the second clamping structure 2 may have plug weld holes.

[0062] Furthermore, the guide hole 33 includes a first hole segment 331 and a second hole segment 332. The diameter of the first hole segment 331 is larger than the diameter of the second hole segment 332, and a stepped surface 333 is formed between the first hole segment 331 and the second hole segment 332. The first end of the guide post 8 has a retaining ring 81, which is located inside the first hole segment 331. The second end of the guide post 8 is connected to the second clamping structure 2. The elastic element 4 is sleeved on the outside of the guide post 8 and connected between the stepped surface 333 and the retaining ring 81. Based on the above structural configuration, the elastic element 4 is connected between the stepped surface 333 and the retaining ring 81, so that the elastic element 4 can provide elastic force to the second clamping structure 2. At the same time, sleeved on the outside of the guide post 8, the elastic element 4 can be prevented from lateral bending during tension or compression, ensuring the stability of the elastic element 4 and effectively improving the service life of the elastic element 4.

[0063] like Figure 1 and Figure 4As shown, in one or more embodiments, the number of elastic elements 4 is set to at least two, and the at least two elastic elements 4 are symmetrically arranged along the length direction of the second clamping structure 2. Based on the above structural configuration, the at least two symmetrically arranged elastic elements 4 can provide a uniform clamping force along the length direction of the second clamping structure 2, ensuring that the clamp can stably clamp the photovoltaic module 9 and avoid stress concentration causing damage to the photovoltaic module 9.

[0064] It should be noted that when the fixture includes guide posts 8, at least two guide posts 8 are provided, and the guide posts 8 are arranged in a one-to-one correspondence with the elastic elements 4.

[0065] like Figure 1 and Figure 4 As shown, in one or more embodiments, the elastic element 4 is configured as a spring. Based on the above structural configuration, the spring can provide the second clamping structure 2 with an elastic force to move towards the first clamping structure 1 to clamp the photovoltaic module 9. Moreover, the spring has low cost, small space occupation, and high energy conversion efficiency, which can meet the design and usage requirements.

[0066] It should be noted that when the elastic element 4 is sleeved outside the guide post 8 and connected between the stepped surface 333 and the retaining ring 81, the elastic element 4 can be a compression spring, which is used to provide the second clamping structure 2 with a force to move towards the first clamping structure 1.

[0067] Those skilled in the art will understand that the elastic element 4 can be configured as a spring, or as a gas spring or other structure that can provide elastic force.

[0068] It should be noted that the above embodiments are only used to illustrate the principle of this utility model and are not intended to limit the scope of protection of this utility model. Without departing from the principle of this utility model, those skilled in the art can adjust the above embodiments so that this utility model can be applied to more specific application scenarios.

[0069] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
