[0001] This application relates to the field of photovoltaic equipment technology, and further to a fastening component and a photovoltaic module frame structure. Background Technology

[0002] Currently, the connection between the frame and support of photovoltaic modules mainly relies on traditional fasteners such as bolts and nuts. This connection method usually requires manual alignment of the fasteners and threading them through holes on the frame and support; however, this process is not only cumbersome but also demands high physical strength and endurance from workers, easily leading to fatigue and inefficiency. Furthermore, due to limited operating space and the instability of worker operation, fasteners are prone to being lost or damaged during installation, increasing material costs and maintenance risks. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this application is to provide a fastening component and a photovoltaic module frame structure that can prevent the loss of fasteners, simplify the operation process, and improve work efficiency.

[0004] To achieve the above objectives, this application provides a fastening assembly for a fastening connection between a photovoltaic module frame and a support member, comprising:

[0005] A matching first fastener and a second fastener, wherein the first fastener is able to form a fixed connection with respect to the second fastener;

[0007] The second fastener can pass through the receiving cavity from the first through hole side and connect with the first fastener to lock the photovoltaic module frame and the support between the first fastener and the second fastener.

[0008] In some embodiments, the receiving cavity includes a first receiving cavity and a second receiving cavity, the fastening assembly includes an auxiliary fastener, the first receiving cavity and the second receiving cavity are continuously disposed and communicate with each other, the first receiving cavity is used to install the first fastener, and the auxiliary fastener is disposed in the first receiving cavity and / or the second receiving cavity;

[0009] When the first fastener and the second fastener are connected, the auxiliary fastener is located between them to enhance the connection stability between the first fastener and the second fastener.

[0010] In some embodiments, the first through hole is an opening on the side of the second receiving cavity away from the first receiving cavity, and the size of the first receiving cavity is smaller than the size of the second receiving cavity. When the support body is connected to the photovoltaic module frame, the end of the support body with the first through hole abuts against the photovoltaic module frame, so that the first through hole is at least partially covered to prevent the first fastener and the auxiliary fastener from coming out of the receiving cavity.

[0011] In some embodiments, the first fastener is a nut and the second fastener is a bolt, the bolt being able to pass through the fixing holes on the photovoltaic module frame and the support member and be connected to the nut;

[0012] The first receiving cavity is provided with a limiting ring edge along its peripheral wall. The contour of the limiting ring edge is consistent with the outer contour of the nut to prevent the nut from deflecting and causing connection failure.

[0013] In some embodiments, a second through hole is provided at the opposite end of the bearing body away from the first through hole. The second through hole communicates with the first receiving cavity, and the diameter of the second through hole is equal to or greater than the diameter of the bolt shank, so that when the bolt and the nut are assembled, at least a portion of the bolt shank can extend out of the first receiving cavity through the second through hole.

[0014] In some embodiments, the number of auxiliary fasteners is at least one, and each auxiliary fastener is one of a flat washer, an elastic washer, and a locking washer.

[0015] In some embodiments, the support body is provided with at least one disassembly port, which is connected to the receiving cavity, for inserting a disassembly tool from the disassembly port into the receiving cavity to remove the support body from the photovoltaic module frame.

[0016] In some embodiments, the supporting body includes two ear plates, which are symmetrically distributed along the central axis of the supporting body. The two ear plates are equipped with fixing members, so that the ear plates can be connected to the photovoltaic module frame through the fixing members, thereby achieving relative fixation between the supporting body and the photovoltaic module frame.

[0017] In some embodiments, the first through hole and any of the ear plates are respectively disposed on different end faces of the supporting body;

[0018] And / or, each of the ear plates is provided with an assembly hole, and the fastener is a nylon rivet. The nylon rivet is disposed in the assembly hole and can be engaged with the fixing hole on the photovoltaic module frame under the action of external force, so as to realize the relative connection between the ear plate and the photovoltaic module frame.

[0019] Another aspect of this application also provides a photovoltaic module frame structure, including:

[0020] The frame body and the aforementioned fastening components, wherein the supporting body is fixedly connected to the frame body, so that the fastening components and the frame body together form a pre-assembled whole.

[0021] Compared with the prior art, the fastening components and photovoltaic module frame structure provided in this application have the following advantages:

[0022] Beneficial effects:

[0023] 1. The fastening components are pre-installed onto the load-bearing body of the photovoltaic module frame, reducing the workload during on-site installation. Since the first fastener is pre-installed within the housing cavity, only the second fastener needs to be connected to the first, simplifying the installation process and saving installation time. Simultaneously, because the first fastener is located within the housing cavity, the possibility of fastener loss during installation is reduced, thereby reducing material waste and additional costs. Furthermore, it provides relative isolation from the external environment, making it less susceptible to direct impacts from external factors such as wind, sun, and rain.

[0024] 2. By setting auxiliary fasteners, such as flat washers and elastic washers, between the first fastener and the second fastener, the connection stability between the two can be significantly enhanced. At the same time, it can disperse pressure and increase friction, thereby reducing the possibility of loosening caused by external forces. Moreover, the auxiliary fasteners are installed in the receiving cavity of the bearing body, reducing the possibility of loss during installation.

[0025] 3. The limiting ring is set along the periphery of the receiving cavity, which provides physical restriction for the nut, ensuring that the nut will not deflect during installation and use, providing a fast tightening speed between the nut and the bolt, and avoiding connection failure caused by nut deflection, thereby improving the reliability of the connection between the entire photovoltaic module and the support.

[0026] 4. The support body is provided with a disassembly port. After the photovoltaic module frame and the support are fixedly connected, the corresponding first and second fasteners are also fixedly connected. The disassembly tool can be inserted into the receiving cavity through the disassembly port to remove the support body from the photovoltaic module frame, so that the support body can be reused.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] In the field of solar photovoltaics, the installation and fixing technology of photovoltaic modules is crucial to ensuring system stability and reliability. Currently, the connection between the frame and support of photovoltaic modules mainly relies on traditional fasteners such as bolts and nuts. This connection method usually requires manual alignment of the fasteners and threading them through holes on the frame and support. This process is not only cumbersome and prone to causing worker fatigue, but also prone to fastener loss, increasing material costs and maintenance risks.

[0042] In one embodiment, refer to the appendix to the specification. Figure 1 The fastening components provided in this application can simplify the connection process between the photovoltaic module frame 1 and the support 2, and can effectively reduce the loss of fasteners, which is beneficial to improving the efficiency and reliability of photovoltaic module installation.

[0043] Reference manual attached Figure 2 , Figure 3 and Figure 5 The fastening assembly provided in this application includes a first fastener 41, a second fastener 42, and a carrier body 3. The carrier body 3 has a receiving cavity 31 and is pre-installed on the photovoltaic module frame 1. A first through hole 301 communicating with the receiving cavity 31 is provided at one end of the carrier body 3.

[0044] The first fastener 41 and the second fastener 42 can be matched and connected. The first fastener 41 is pre-installed in the receiving cavity 31, while the second fastener 42 can pass through the receiving cavity 31 from the first through hole 301 side and connect with the first fastener 41 to lock the photovoltaic module frame 1 and the support member 2 between the first fastener 41 and the second fastener 42, so as to realize the rapid fastening between the photovoltaic module and the support member 2.

[0045] Understandably, in this embodiment, since the first fastener 41 is pre-installed within the supporting body 3, the pre-positioning achieved reduces on-site alignment and positioning to a certain extent, significantly improving installation efficiency and shortening the project cycle. Simultaneously, the pre-installation design reduces the risk of fasteners being lost during installation, lowering additional costs due to loss or damage. Furthermore, since the first fastener 41 is located within the receiving cavity 31, it is less susceptible to external corrosion, improving the fastener's corrosion resistance.

[0046] In this embodiment, the photovoltaic module frame 1 and the support member 2 are locked by connecting the first fastener 41 and the second fastener 42. Optionally, as shown in the accompanying drawings of this application, the first fastener 41 is a nut. In some designs, the nut can be a standard part or it can be customized according to specific installation requirements, such as using nylon material to improve corrosion resistance. The second fastener 42 is a bolt. The bolt selection should be based on its length, diameter, and material to adapt to different installation requirements and environmental conditions. In this case, the second fastener 42 can pass through the fixing holes on the photovoltaic module frame 1 and the support member 2 to connect with the first fastener 41, providing a more direct connection method.

[0047] Besides the traditional bolt and nut combination, other fasteners can achieve a similar fastening effect. For example, the second fastener 42 can be a snap-fit, such as a U-shaped snap-fit, and the first fastener 41 can be a snap block. The two ends of the snap-fit ​​can engage with the corresponding snap blocks to form an annular mounting cavity, thereby fixing the support 2. This not only provides the possibility of quick installation, but also allows fastening without penetrating the support 2.

[0048] Based on the above, optionally, a locking device, such as a fixing clamp, can be integrated into the bearing body 3 to provide additional locking force and prevent the first fastener 41 from loosening.

[0049] In one embodiment, such as Figure 3As shown, the fastening assembly also includes auxiliary fasteners 43. The receiving cavity 31 of the bearing body 3 includes a first receiving cavity 311 and a second receiving cavity 312. The first receiving cavity 311 and the second receiving cavity 312 are continuously arranged and interconnected. The first fastener 41 is installed in the first receiving cavity 311. The auxiliary fastener 43 can be configured in the first receiving cavity 311, the second receiving cavity 312, or both receiving cavities, depending on the specific configuration. In some cases, in order to enhance the stability and durability of the connection, different types of auxiliary fasteners 43 may be installed in both receiving cavities at the same time.

[0050] When the first fastener 41 and the second fastener 42 are connected, the auxiliary fastener 43 is located between the first fastener 41 and the second fastener 42, thereby enhancing the connection stability between the two and reducing the possibility of loosening caused by external forces.

[0051] Referring to the attached diagram in the instruction manual, since the first fastener 41 and the auxiliary fastener 43 are both pre-installed in the receiving cavity 31 of the supporting body 3, during on-site installation, it is only necessary to pass the second fastener 42 through the photovoltaic module frame 1 and the support 2 and connect it with the first fastener 41, which greatly simplifies the installation steps.

[0052] In one embodiment, such as Figure 3 and Figure 5 As shown, the first through hole 301 is the opening of the second receiving cavity 312 on the side away from the first receiving cavity 311, and the width of the first receiving cavity 311 is smaller than the width of the second receiving cavity 312. This allows the large-diameter second receiving cavity 312 to be close to the outer side of the supporting body 3, thereby facilitating the assembly of the first fastener 41 and the auxiliary fastener 43. Understandably, during assembly, the operator can more easily place the first fastener 41 and the auxiliary fastener 43 into the supporting body 3, reducing assembly difficulty and time.

[0053] Furthermore, based on the above content, please refer to the appendix. Figure 2 When the supporting body 3 is connected to the photovoltaic module frame 1, one end of the supporting body 3, that is, the end with the first through hole 301, abuts against the photovoltaic module frame 1, so that the first through hole 301 is at least partially covered, thereby effectively preventing the first fastener 41 and the auxiliary fastener 43 from coming out of the receiving cavity 31.

[0054] It should be noted that, in use, the photovoltaic module frame 1 provides some coverage over the first through-hole 301, ensuring that the first fastener 41 and the auxiliary fastener 43 will not come out of the receiving cavity 31, thus improving the safety and reliability of the system. Furthermore, this configuration in this embodiment also helps improve the overall sealing performance. When the supporting body 3 does not have other perforated structures communicating with the receiving cavity 31, it can prevent moisture, dust, and other external impurities from entering the receiving cavity 31, thereby protecting the fasteners from corrosion and contamination.

[0055] In addition, since the supporting body 3 needs to be in contact with the photovoltaic module frame 1, the stability of the structure is improved. The supporting body 3 is not easy to shake or shift, thus improving the installation accuracy and reliability.

[0056] In contrast, in another form, the side face of the supporting body 3 with the first through hole 301 itself has a barrier, meaning that the fastener will not come out from this side. In this form, the first through hole 301 is only used for the connection of the second fastener 42, while the opening of the second receiving cavity 312 is formed on other end faces of the supporting body 3. The first form protects the internal fasteners through the physical coverage of the photovoltaic module frame 1, while the second form achieves this through the structural design of the supporting body 3 itself.

[0057] The specific configuration depends on the outline of the photovoltaic module frame 1. If the photovoltaic module frame 1 has two end faces that can be connected to the supporting body 3, then one end face can be provided with the opening of the second receiving cavity 312, and the other end face can be provided with the first through hole 301. If there are few end faces that can be connected on the photovoltaic module frame 1, then the opening of the second receiving cavity 312 and the first through hole 301 can also be made to coincide on one end face.

[0058] It should be noted that, based on the above embodiments, the auxiliary fastener 43 can be configured in various ways, such as a flat washer 431, an elastic washer 432, a locking washer, or a stop washer.

[0059] In one embodiment, the number of auxiliary fasteners 43 is at least one; in other words, in a particular embodiment, one or more auxiliary fasteners 43 can be used as needed to meet different fastening requirements. For example, in the attached... Figure 3 In the illustrated embodiment, two auxiliary fasteners 43 are provided within the receiving cavity 31 to provide additional stability and preload. These two auxiliary fasteners 43 are a flat washer 431 and a resilient washer 432, a combination that provides multiple functions, including pressure distribution, preventing loosening, and providing elastic cushioning. The resilient washer 432 is placed between the first receiving cavity 311 and the second receiving cavity 312 to provide preload, while the flat washer 431 is disposed within the second receiving cavity 312 to protect the surface of the photovoltaic module frame 1.

[0060] Specifically, regarding the use of the flat washer 431, in use, the flat washer 431 directly abuts against the surface of the photovoltaic module frame 1 to prevent surface wear. Additionally, during actual installation, the operator can also place a flat washer 431 between the support member 2 and the second fastener 42 to provide extra protection and stability. Understandably, the main function of the flat washer 431 is to protect the surfaces of the photovoltaic module frame 1 and the support member 2, preventing wear or damage to the surface of the frame or support member 2 due to the pressure of the fasteners during tightening. The flat surface of the flat washer 431 can disperse the pressure of the fasteners, reducing localized stress concentration on the module.

[0061] Regarding the use of the elastic washer 432, in the application state, the elastic washer 432 is placed between the flat washer 431 and the first fastener 41 to provide elastic preload and prevent the first fastener 41 from loosening due to external forces (such as vibration, wind load, etc.). At the same time, the elastic washer 432 has a certain shock absorption capacity, which can absorb the energy caused by external impact or vibration, and reduce the impact of these factors on the connection stability.

[0062] In one embodiment, based on the above embodiments, the first fastener 41 is a nut and the second fastener 42 is a bolt. The bolt can pass through the fixing holes on the photovoltaic module frame 1 and the support 2 and connect with the nut, thereby firmly fixing the photovoltaic module to the support 2.

[0063] Importantly, in this embodiment, as Figure 5 As shown, the first receiving cavity 311 is provided with a limiting ring edge 3121 along its peripheral wall. The outline of the limiting ring edge 3121 is consistent with the outer outline of the nut, which ensures the precise positioning of the nut in the first receiving cavity 311 and effectively prevents the nut from deflecting during installation or use, thereby avoiding the risk of connection failure.

[0064] Understandably, during installation, bolts pass through the fixing holes on the photovoltaic module frame 1 and the support 2 to connect with nuts. Due to the presence of the limiting ring edge 3121, the nut is firmly positioned in the predetermined position and will not deflect even during bolt tightening, effectively avoiding connection failure caused by inaccurate nut positioning.

[0065] Based on this embodiment, optionally, the limiting ring edge 3121 can be provided with an anti-wear material, such as high-performance plastic or special rubber, to reduce friction between the nut and the bearing body 3, thereby reducing the wear rate and extending the service life of the nut and the bearing body 3. Alternatively, an elastic buffer material can also be provided on the limiting ring edge 3121 to absorb energy caused by external impact or vibration, reducing the impact of these factors on the connection stability.

[0066] In one embodiment, based on the above embodiments, refer to the appendix to the specification. Figure 6 The supporting body 3 has a second through hole 302 at the opposite end of the side away from the first through hole 301. The second through hole 302 is connected to the first receiving cavity 311. The diameter of the second through hole 302 is equal to or greater than the diameter of the bolt shank, so that during assembly, the bolt shank can partially pass through the second through hole 302 and extend out of the first receiving cavity 311.

[0067] It should be noted that the second through hole 302 allows the fastening assembly to adapt to diverse installation requirements with different bolt lengths, especially in situations where bolt lengths may vary due to design or site conditions, thus maximizing bolt length standardization. Specifically, the design of the second through hole 302 takes into account potential differences in bolt lengths, including variations due to machining errors or design requirements. The design in this embodiment ensures that even with longer bolts, their heads can still press firmly against the photovoltaic module frame 1 and the support member 2, achieving a stable connection.

[0068] In addition, the bolt shank extending through the second through hole 302 allows assemblers to visually observe the position and condition of the bolt, thus helping to determine whether the bolt is correctly aligned with the nut and whether it is installed in place, thereby improving the accuracy and efficiency of assembly.

[0069] In one embodiment, such as Figure 2 and Figure 4 As shown, the supporting body 3 includes two ear plates 32, which are symmetrically distributed along the central axis of the supporting body 3. This symmetrical layout not only provides structural balance but also enhances the stability of the connection between the supporting body 3 and the photovoltaic module frame 1. Each ear plate 32 is pre-installed with a fixing member 5, and the ear plate 32 is connected to the photovoltaic module frame 1 through the fixing member 5, thereby achieving relative fixation between the supporting body 3 and the photovoltaic module frame 1.

[0070] In this embodiment, the supporting body 3 can be adapted to photovoltaic module frames 1 of different sizes and shapes by means of the fastener 5 on the ear plate 32, which improves the versatility and adaptability of the fastening components. In addition, since the fastener 5 on the ear plate 32 can be pre-installed, for example, it has been installed during production in the factory, and the ear plate 32 only needs to be fixed to the photovoltaic module frame 1 during on-site assembly, which greatly simplifies the assembly process and improves the installation efficiency.

[0071] In a specific embodiment, the ear plate 32 can be connected to the supporting body 3 by welding, riveting, or integral molding. The fastener 5 can be bolts, screws, clips, etc., and the appropriate fastening method should be selected according to the material and thickness of the photovoltaic module frame 1. During assembly, the ear plate 32 is aligned with the preset holes on the photovoltaic module frame 1, and the ear plate 32 is fastened to the frame by the fastener 5, thus completing the connection between the supporting body 3 and the photovoltaic module frame 1.

[0072] Furthermore, the first through hole 301 and the ear plate 32 can be located on the same end face of the supporting body 3, or they can be located on different end faces. It is easy to understand that in the former case, when the supporting body 3 is fixed to the photovoltaic module frame 1, the first through hole 301 and the ear plate 32 are connected to the same end face; in the latter case, as shown in the figure, the first through hole 301 and the ear plate 32 are respectively set on different end faces of the supporting body 3, and at this time the photovoltaic module frame 1 has at least two mating end faces to respectively connect the ear plate 32 and the first through hole 301.

[0073] In addition, based on the above, each ear plate 32 is provided with an assembly hole, and the fastener 5 is a nylon rivet. The nylon rivet is set in the assembly hole and can be inserted into the fixing hole on the photovoltaic module frame 1 under external force to realize the relative connection between the ear plate 32 and the photovoltaic module frame 1.

[0074] In this embodiment, the use of nylon rivets simplifies the connection process. No complicated tools or additional operations are required. The connection can be completed simply by inserting the nylon rivet into the fixing hole of the photovoltaic module frame 1. The nylon rivet can be firmly locked in the fixing hole of the photovoltaic module frame 1 after being subjected to force, providing a stable connection that is suitable for withstanding various loads in outdoor environments.

[0075] In one embodiment, the support body 3 is provided with at least one disassembly port 33, which is connected to the receiving cavity 31 inside the support body 3.

[0076] Understandably, after the supporting body 3 is installed onto the photovoltaic module frame 1 using fasteners 5, such as nylon rivets, it may need to be removed for maintenance or replacement. Since there may be a large number of fasteners 5, or they may be difficult to remove manually, an operator can insert a disassembly tool into the receiving cavity 31 through the disassembly port 33. This tool can be a screwdriver, pry bar, or other suitable prying tool. The operator inserts the tool into the disassembly port 33 and uses leverage to pry the supporting body 3, causing it to detach from the photovoltaic module frame 1. The disassembly port 33 can be designed as a slit or a hole, such as the perforated structure shown in the attached diagram.

[0077] In one embodiment, referring to the accompanying drawings, according to another aspect of this application, this application further provides a photovoltaic module frame structure, including a frame body and the aforementioned fastening components. The supporting body 3 is fixedly connected to the frame body, such that the fastening components and the frame body together form a pre-assembled whole.

[0078] In this embodiment, the frame body can be understood as the photovoltaic module frame 1 mentioned above. Through this configuration, the photovoltaic module frame body is pre-assembled with fastening components at the factory. Upon arrival at the construction site, it only needs to be directly connected to the support component 2, such as the purlin, thus significantly saving installation time and labor costs. Furthermore, pre-assembly in the factory environment ensures the installation quality of the fastening components, avoiding problems that may arise during on-site installation due to environmental factors or improper operation.

[0079] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
