Description

Technical Field

[0001] This application belongs to the field of photovoltaic technology, and in particular relates to a module frame, a photovoltaic module, and a photovoltaic system. Background Technology

[0002] During the installation of photovoltaic modules, the module frame plays a crucial role in fixing and protecting the photovoltaic laminate. Traditionally, the connection between the frame and the mounting block is usually achieved using bolts. During installation, the mounting block must first be precisely positioned, and then bolts, nuts, washers, and other components must be installed sequentially. Finally, tools such as wrenches and screwdrivers are needed to tighten the bolts, making the entire installation process complex, cumbersome, time-consuming, and labor-intensive.

[0003] Especially in confined spaces or special environments, the above installation methods present numerous problems. For example, in places with limited space, tools such as wrenches and screwdrivers are difficult to operate normally, making the installation process extremely complicated and potentially leading to situations where installation is impossible or not secure, seriously affecting the installation quality and stability of photovoltaic modules. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a component frame, a photovoltaic module, and a photovoltaic system, which realizes quick and convenient installation and disassembly between the frame body and the clamping block, saving material costs, loading and unloading time, and labor costs.

[0005] In a first aspect, this application provides a component border, including: Border body; The pressure block is installed outside the frame body; The fastener includes a pin, a pressing member, and an operating member. The pressing member is sleeved on the pin, and the operating member is hinged to the pin. The pin passes through the frame body and the pressure block. The operating member has a first posture and a second posture. When the operating member switches from the first posture to the second posture, the operating member is adapted to press the pressing member so that the pin and the pressing member clamp the frame body and the pressure block.

[0006] According to the component frame of this application, through the cooperative design between the fasteners, the assembly part of the frame body, and the connecting holes of the pressure block, quick and convenient installation and disassembly between the frame body and the pressure block are realized. The installation and disassembly operations can be completed by pulling the operating part, which can be operated with one hand without the need for auxiliary tools such as wrenches and screwdrivers, thereby greatly saving installation and disassembly time and labor costs, and thus significantly improving the maintainability of photovoltaic modules. At the same time, it enables the component frame to better adapt to the usage needs of confined spaces or special environments, improves the compatibility and practicality of the component frame, and thus improves the installation quality, structural reliability and stability of photovoltaic modules in complex environments.

[0007] According to one embodiment of this application, the pressing member includes: A support ring is fitted over the shaft portion of the pin. An elastic element is sleeved outside the rod portion of the pin, located between the head of the pin and the support ring, and is adapted to be elastically compressed between the support ring and the pressure block.

[0008] According to the component frame of this application, by configuring the pressing member as composed of a support ring and an elastic member, on the one hand, the elastic force of the elastic member acts between the support ring and the pressing block, so that the frame body and the pressing block are subjected to a greater clamping force, which can more effectively prevent the frame body and the pressing block from loosening or separating during use, greatly improving the stability and reliability of the component frame connection. On the other hand, the elastic member can absorb and buffer the impact and vibration energy generated by external forces such as wind and object collisions, reducing damage to the frame body, the pressing block and the entire component structure, thereby extending the service life of the component. Furthermore, when the frame body and the pressing block are subjected to a certain degree of thermal expansion and contraction or other minor deformations, the elastic member can adapt to these changes through its own elastic deformation, always maintaining the clamping force on the frame body and the pressing block, solving the problem of connection loosening caused by deformation, thereby improving the adaptability of the component frame to different environmental conditions. Moreover, the elastic member can also compensate for the installation errors between the frame body, the pressing block and the fasteners through elastic deformation, thereby improving the installation error tolerance and reducing the installation difficulty.

[0009] According to one embodiment of this application, the operating member has a first contact surface and a second contact surface adapted to abut against the pressing member. In the first posture, the first contact surface abuts against the pressing member, and in the second posture, the second contact surface abuts against the pressing member. In the first posture, the distance between the first contact surface and the head of the pin is greater than the distance between the second contact surface and the head of the pin in the second posture.

[0010] According to one embodiment of this application, the fastener further includes: A pivot shaft is provided, and the operating element is pivotally mounted on the end of the pin shaft away from the head via the pivot shaft. The distance from the first contact surface to the central axis of the pivot shaft is less than the distance from the second contact surface to the central axis of the pivot shaft.

[0011] According to one embodiment of this application, the operating element is provided with a guide arc surface connecting the first contact surface and the second contact surface.

[0012] According to one embodiment of this application, the frame body is provided with an assembly part, the assembly part including a through hole and a limiting hole, the head of the pin is adapted to pass through the through hole, the pressure block is provided with a connecting hole, and the rod of the pin passes through the limiting hole and the through hole.

[0013] According to one embodiment of this application, the assembly portion further includes a channel communicating between the through hole and the limiting hole, and the rod portion is adapted to slide with the channel.

[0014] According to one embodiment of this application, the frame body includes a plurality of side beams connected end to end in sequence. Each side beam includes a top plate, a side plate, and a bottom plate connected in sequence. The pressure block includes a first plate, a second plate, and a third plate that are bent and connected in sequence. The first plate abuts against the top plate, the second plate abuts against the side plate, and the third plate is connected to the bottom plate by the fastener.

[0015] According to one embodiment of this application, one of the second plate and the beam side plate is provided with a locking block, and the other is provided with a locking groove for engaging with the locking block.

[0016] Secondly, this application provides a photovoltaic module, which includes: Photovoltaic laminates; As described in any of the above embodiments, the photovoltaic laminate is mounted on the component frame.

[0017] According to the photovoltaic module of this application, the aforementioned module frame design enables quick and convenient installation and disassembly between the frame body and the pressure block. Installation and disassembly can be completed by simply pulling the operating parts, which can be operated with one hand without the need for auxiliary tools such as wrenches and screwdrivers. This significantly saves installation and disassembly time and labor costs, thereby significantly improving the maintainability of the photovoltaic module. At the same time, it allows the module frame to better adapt to the usage needs of confined spaces or special environments, improving the compatibility and practicality of the module frame, thereby enhancing the installation quality, structural reliability, and stability of the photovoltaic module in complex environments.

[0018] Thirdly, this application provides a photovoltaic system, which includes: Photovoltaic support system; The photovoltaic modules described above are installed on the photovoltaic support structure.

[0019] According to the photovoltaic system of this application, the above-mentioned photovoltaic module configuration enables quick and convenient installation and disassembly between the frame body and the pressure block. The installation and disassembly operations can be completed by pulling the operating parts, which can be operated with one hand without the need for auxiliary tools such as wrenches and screwdrivers. This significantly saves installation and disassembly time and labor costs, thereby significantly improving the maintainability of the photovoltaic module. At the same time, it enables the module frame to better adapt to the usage needs of confined spaces or special environments, improving the compatibility and practicality of the module frame, thereby improving the installation quality, structural reliability and stability of the photovoltaic module in complex environments.

Detailed Implementation

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0024] This application discloses a component border 10.

[0025] The following is for reference. Figures 1-9 The component border 10 according to an embodiment of this application is described.

[0026] In some embodiments, such as Figures 1-4 As shown, the component frame 10 includes: frame body 11, pressure block 12 and fastener 13.

[0027] like Figures 1-6 As shown, the pressure block 12 is installed outside the frame body 11, and the pressure block 12 is provided with a connecting hole 1231; the fastener 13 includes a pin 131, a pressing member 132 and an operating member 133. The pressing member 132 is sleeved outside the pin 131, and the operating member 133 is hinged to the pin 131. The pin 131 passes through the frame body 11 and the pressure block 12. The operating member 133 has a first posture and a second posture. When the operating member 133 switches from the first posture to the second posture, the operating member 133 is adapted to press the pressing member 132 so that the pin 131 and the pressing member 132 clamp the frame body 11 and the pressure block 12.

[0028] like Figure 1 As shown, the frame body 11 has a mounting groove 1101 for inserting photovoltaic laminates. The mounting groove 1101 can provide a stable mounting position for the photovoltaic laminates and play a role in fixing and protecting the photovoltaic laminates.

[0029] Fastener 13, as a key component connecting frame body 11 and pressure block 12, achieves quick clamping or loosening through its own structure, thus enabling it to replace the combination of traditional bolts, nuts and washers.

[0030] The pin 131 of the fastener 13 includes a head 1311 and a rod 1312. The head 1311 is used to cooperate with the pressing member 132 to clamp the frame body 11 and the pressure block 12; the rod 1312 serves to connect and position.

[0031] The head 1311 can be designed as a circle, square, pentagon, hexagon or other shapes, and this application embodiment does not limit this.

[0032] The pressing part 132 of the fastener 13 is used to clamp the frame body 11 and the pressure block 12 together with the head 1311 of the pin 131 under the action of the operating part 133, so as to ensure the stability of the connection.

[0033] The operating part 133 of the fastener 13 is hinged to the rod 1312, such as by means of a pin, hinge, etc. The operator can change the relative position of the operating part 133 and the pressing part 132 by moving the operating part 133, thereby realizing pressure control of the pressing part 132 and thus completing the installation or disassembly operation.

[0034] It should be noted that the first posture and the second posture are two different position states of the operating member 133. The operating member 133 can switch between the first posture and the second posture to achieve different functions, namely, change the way the pressing member 132 is acted, thereby affecting the clamping degree of the entire fastener 13 on the frame body 11 and the pressure block 12.

[0035] In actual implementation, such as Figure 1 and Figure 2 As shown, during the installation of the frame body 11 and the pressure block 12, the pre-installed fasteners 13 are installed at the target positions of the frame body 11 and the pressure block 12, so that the rod portion 1312 of the pin 131 can pass through the frame body 11 and the pressure block 12 in sequence. At this time, the operating member 133 is in the first posture, and the head of the pin 131 and the pressing member 132 have no clamping force or apply a slight clamping force to the frame body 11 and the pressure block 12. Then, the operating member 133 is turned to drive the operating member 133 to rotate around the hinge point until the pressing member 132 is pressed. At this time, the operating member 133 completes the working state switch from the first posture to the second posture. Under this condition, the pressure block 12 and the frame body 11 are firmly clamped between the pressing member 132 and the head 1311 of the pin 131, and the installation is completed.

[0036] During the disassembly of the frame body 11 and the pressure block 12, the operating member 133 is reversed and rotated around the hinge point to release the pressure member 132, thereby relieving the clamping force on the pressure block 12 and the frame body 11.

[0037] The component frame 10 provided in this application embodiment, through the cooperative design between the fastener 13, the assembly part 1131 of the frame body 11, and the connecting hole 1231 of the pressure block 12, realizes quick and convenient installation and disassembly between the frame body 11 and the pressure block 12. The installation and disassembly operations can be completed by pulling the operating part 133, which can be operated with one hand without the need for auxiliary tools such as wrenches and screwdrivers, thereby greatly saving installation and disassembly time and labor costs, and thus significantly improving the maintainability of photovoltaic modules. At the same time, it enables the component frame 10 to better adapt to the usage needs of confined spaces or special environments, improves the compatibility and practicality of the component frame 10, and thus improves the installation quality, structural reliability and stability of photovoltaic modules in complex environments.

[0038] In some embodiments, such as Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the pressing member 132 includes a support ring 1321 and an elastic member 1322.

[0039] The support ring 1321 is sleeved on the rod portion 1312 of the pin 131; the elastic element 1322 is sleeved on the rod portion 1312 of the pin 131, and the elastic element 1322 is located between the head 1311 of the pin 131 and the support ring 1321. The elastic element 1322 is adapted to be elastically compressed between the support ring 1321 and the pressure block 12.

[0040] In other words, the elastic element 1322 is on the head 1311 side, and the support ring 1321 is on the pressure block 12 side. The support ring 1321, as a rigid intermediate structure, on the one hand, bears the elastic pressure of the elastic element 1322, and on the other hand, transmits the pressure evenly to the surface of the pressure block 12, so as to avoid local stress concentration or wear caused by the elastic element 1322 directly contacting the pressure block 12.

[0041] The elastic element 1322 can provide continuous axial pressure through its own elastic deformation. When the operating element 133 is pressed, the operator needs to overcome the elastic force to engage it. The elastic element 1322 is compressed by the external force and stores elastic potential energy, thus achieving flexible clamping between the frame body 11 and the pressure block 12. Furthermore, the elastic element 1322 has recoverable deformation capability, which can compensate for dimensional fluctuations caused by installation gaps, temperature changes, or vibrations, and maintain the long-term stability of the clamping force.

[0042] When the operating member 133 is released, the elastic member 1322 gradually returns to its original position, that is, the elastic force gradually decreases until the elastic member 1322 is stable. Specifically, when the elastic member 1322 returns to its stable position, the elastic member 1322 can be in a slightly compressed state (that is, the amount of compression is much smaller than the amount of compression of the elastic member 1322 when the operating member 133 is pressed) or in a natural state (that is, it is supported on the support ring 1321 only under its own gravity).

[0043] The elastic element 1322 can be, but is not limited to, a spring, an elastic sleeve, a spring bar, or a spring sheet, etc., and the embodiments of this application do not limit this.

[0044] For example, the support ring 1321 may be provided with a groove, and the end of the elastic member 1322 may be installed in the groove to facilitate the positioning and assembly of the elastic member 1322 and improve the positional accuracy of the elastic member 1322.

[0045] The component frame 10 provided in this application embodiment, by configuring the pressing member 132 as composed of a support ring 1321 and an elastic member 1322, has several advantages. Firstly, the elastic force of the elastic member 1322 acts between the support ring 1321 and the pressing block 12, resulting in a greater clamping force on the frame body 11 and the pressing block 12. This effectively prevents loosening or separation of the frame body 11 and the pressing block 12 during use, significantly improving the stability and reliability of the component frame 10 connection. Secondly, the elastic member 1322 can absorb and buffer the impact and vibration energy generated by external forces such as wind and object collisions, reducing damage to the frame body 11, the pressing block 12, and the entire component structure, thereby extending the component's service life. Thirdly, when the frame body 11 and the pressing block 12 are subjected to a certain degree of thermal expansion and contraction or other minor deformations, the elastic member 1322 can adapt to these changes through its own elastic deformation, maintaining a constant clamping force on the frame body 11 and the pressing block 12. This solves the problem of loosening caused by deformation, thereby improving the adaptability of the component frame 10 to different environmental conditions. On the other hand, the elastic element 1322 can also compensate for the installation error between the frame body 11, the pressure block 12 and the fastener 13 through elastic deformation, thereby improving the fault tolerance rate of installation and reducing the installation difficulty.

[0046] In some embodiments, such as Figures 1-4 , Figure 8 and Figure 9As shown, the operating member 133 has a first contact surface 1331 and a second contact surface 1332 adapted to abut against the pressing member 132. In a first posture, the first contact surface 1331 abuts against the pressing member 132. In a second posture, the second contact surface 1332 abuts against the pressing member 132. In the first posture, the distance h1 between the first contact surface 1331 and the head 1311 of the pin 131 is greater than the distance h2 between the second contact surface 1332 and the head 1311 of the pin 131 in the second posture.

[0047] It should be noted that the first contact surface 1331 and the second contact surface 1332 are two different surfaces on the operating member 133 that are used to contact the pressing member 132. These two contact surfaces abut against the pressing member 132 when the operating member 133 is in different postures. Different contact surfaces abut against the pressing member 132 will produce different effects, thereby changing the way and magnitude of the pressure applied by the operating member 133 to the pressing member 132.

[0048] like Figure 3 and Figure 4 As shown, based on h1>h2, the compression amount of elastic element 1322 in the first state is less than that in the second state. Therefore, the elastic force generated by elastic element 1322 in the first state is less than that generated by elastic element 1322 in the second state.

[0049] like Figure 1 and Figure 3 As shown, when the operating member 133 is in the first posture, the support ring 1321 and the elastic member 1322 are supported on the first contact surface 1331 of the operating member 133 only under their own weight, or the first contact surface 1331 of the operating member 133 applies a slight compressive stress to the support ring 1321 and the elastic member 1322.

[0050] like Figure 2 , Figure 4 , Figure 8 and Figure 9 As shown, when the operating member 133 is in the second posture, the second contact surface 1332 of the operating member 133 presses the support ring 1321, thereby driving the support ring 1321 to further compress the elastic member 1322, generating a greater clamping force, thereby realizing the firm clamping of the elastic member 1322 and the head 1311 on the frame body 11 and the pressure block 12.

[0051] The first contact surface 1331 and the second contact surface 1332 are located at different positions of the operating member 133. As the operating member 133 rotates, they alternately contact the pressing member 132. The difference in distance between the two and the head 1311 directly determines the difference in compression stroke of the pressing member 132 and the variation range of clamping force.

[0052] The component frame 10 provided in this application embodiment utilizes the motion matching mechanism of the dual posture and dual contact surface of the operating element 133. By switching between the first and second postures of the operating element 133, clamping and loosening of the frame body 11 and the pressure block 12 can be achieved with a simple tossing operation, without the need for complex tools or cumbersome operating steps. Compared with the traditional bolt connection method, this greatly simplifies the installation and disassembly process and improves work efficiency. At the same time, the clamping force can be adjusted according to actual needs by adjusting h1 and h2 during the design. This allows the operating element 133 to be switched to a suitable posture to obtain the best clamping effect, thereby improving the stability and reliability of the component frame 10 connection. Furthermore, no additional complex structure is required to adjust the clamping force. The function can be completed simply by the posture switching and contact surface change of the operating element 133 itself, making the structure of the entire component frame 10 more compact. This not only saves space but also facilitates installation and use in confined spaces or special environments, improving the applicability and practicality of the fastener 13.

[0053] In some embodiments, such as Figures 1-4 , Figure 8 and Figure 9 As shown, the fastener 13 also includes a rotating shaft 134.

[0054] The operating element 133 is pivotally mounted on the end of the rod portion 1312 of the pin 131 away from the head 1311 via the pivot 134. The distance L1 from the first contact surface 1331 to the central axis of the pivot 134 is less than the distance L2 from the second contact surface 1332 to the central axis of the pivot 134.

[0055] The pivot 134 is the connecting hub between the operating member 133 and the rod portion 1312 of the pin 131. The operating member 133 is pivotally mounted on the end of the rod portion 1312 away from the head 1311 (i.e., the end of the rod portion 1312 away from the head 1311 of the pin 131). The central axis of the pivot 134 is the rotation center of the operating member 133, ensuring that the operating member 133 can stably switch between the first and second postures around the central axis.

[0056] like Figure 3 and Figure 4As shown, since L1<L2, in other words, when the operating member 133 is processed and manufactured, a through hole for inserting the rotating shaft 134 is provided, and after the operating member 133 is formed, the design principle that the first contact surface 1331 is closer to the through hole than the second contact surface 1332 is satisfied. When the distance from the central axis of the rotating shaft 134 to the head 1311 is fixed, according to the geometric relationship, the closer the distance from the contact surface to the central axis, the farther the distance from the contact surface to the head 1311; conversely, the farther the distance from the contact surface to the central axis, the closer the distance from the contact surface to the head 1311. This provides structural support for the aforementioned condition that the spacing h1 between the first contact surface 1331 and the head 1311 in the first posture is greater than the spacing h2 between the second contact surface 1332 and the head 1311 in the second posture.

[0057] It should be noted that, in order to increase the stability of the operating member 133 in the first posture and / or the second posture, the operating member 133 can be stably maintained in the first posture and / or the second posture through a rotary damper, a buckle, a gear, a ratchet, a spring lock, a limit block, a friction plate or other limit structures, which is not limited in the embodiments of the present application.

[0058] The component bezel 10 provided by the embodiment of the present application, through the above structural design that the distance L1 from the first contact surface 1331 to the central axis of the rotating shaft 134 is smaller than the distance L2 from the second contact surface 1332 to the central axis of the rotating shaft 134, establishes a linkage mechanism between L1 and h1 and a linkage mechanism between L2 and h2, structurally ensures the realization of h1>h2, which is the core support of the entire clamping logic, and avoids the clamping failure caused by unreasonable structural design. In addition, when processing and manufacturing the operating member 133, it only needs to arrange the through hole for inserting the rotating shaft 134 in accordance with the design principle, and ensure that after the operating member 133 is formed, the first contact surface 1331 is closer to the through hole than the second contact surface 1332. This design is relatively simple, does not require complicated processing technology or special processing equipment, is conducive to reducing production costs and improving production efficiency. At the same time, it is also convenient for quality inspection and control of the operating member 133, and maintains the consistency and stability of the product.

[0059] In some embodiments, as Figure 3 , Figure 4 , Figure 8 and Figure 9 shown, the operating member 133 is provided with a guide arc surface 1333 connected between the first contact surface 1331 and the second contact surface 1332.

[0060] The guide arc surface 1333 is a transitional curved surface connecting the first contact surface 1331 and the second contact surface 1332 on the operating component 133. When the operating component 133 rotates around the rotating shaft 134 to switch postures, the guide arc surface 1333 and the pressing component 132 engage in frictional contact. The guide arc surface 1333 can play a guiding and transitional role, making the transition of the operating component 133 between the two postures smoother and reducing the occurrence of jamming or sudden impact. At the same time, it reduces the fatigue wear of the operating component 133 under long-term use, thereby extending the service life of the fastener 13.

[0061] For example, such as Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the guide arc surface 1333 can be an arc surface with the center of curvature located within the operating member 133, and the first contact surface 1331 and the second contact surface 1332 can be tangent to the two ends of the guide arc surface 1333 respectively.

[0062] It should be noted that, as Figure 8 and Figure 9 As shown, the operating member 133 can also have a notch cut on the side of the second contact surface 1332 opposite to the first contact surface 1331 to form a stepped structure, which can reduce its own weight while indicating the operating position and making it easy to operate.

[0063] The component frame 10 provided in this application embodiment, through the setting of the aforementioned guide arc surface 1333, on the one hand, guides the sliding of the pressure member 132 through the continuous curved surface, significantly reducing the resistance during the switching process, allowing the operator to easily complete the posture change with one hand. For the case where the pressure member 132 includes the elastic member 1322 and the support ring 1321, the smooth transition can reduce the instantaneous vibration generated by the elastic member 1322, reduce fatigue damage to the components, and extend the service life of the elastic member 1322. On the other hand, the guide arc surface 1333 makes the clamping force increase linearly or gradually with the rotation angle of the operating member 133, rather than a step-like abrupt change, which can precisely control the rate of force change, thereby greatly reducing the risk of cracking or deformation caused by instantaneous impact force. Furthermore, during the posture switching process, the guide arc surface 1333 can disperse and transition the force acting on the operating member 133, reducing the stress concentrated at the connection between the first contact surface 1331 and the second contact surface 1332. This reduces the risk of fatigue damage and fracture caused by stress concentration at the connection, and improves the structural strength and reliability of the operating component 133.

[0064] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the frame body 11 is provided with an assembly part 1131, which includes a through hole 11311 and a limiting hole 11312. The head 1311 of the pin 131 is adapted to pass through the through hole 11311. The pressure block 12 is provided with a connecting hole 1231. When the operating member 133 is in the second posture, the rod part 1312 of the pin 131 passes through the limiting hole 11312 and the connecting hole 1231.

[0065] The through hole 11311 on the frame body 11 is mainly used to allow the head 1311 of the pin 131 to pass through during installation. The limiting hole 11312 on the frame body 11 is used to limit the fastener 13 after installation to prevent it from shaking or falling off. The shape and size of the through hole 11311 and the limiting hole 11312 can be determined according to actual design requirements. Specifically, they can be including but not limited to circles, squares, pentagons or hexagons, etc. This application embodiment does not limit them.

[0066] The pressure block 12 is used to cooperate with the frame body 11 to fix the photovoltaic laminate. The size and position of the connecting hole 1231 on the pressure block 12 are adapted to the fastener 13 and are used to connect with the fastener 13 to fix the pressure block 12 and the frame body 11.

[0067] For example, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the size of the head 1311 of the pin 131 is smaller than the size of the through hole 11311, while the size of both the head 1311 and the pressing member 132 are larger than the sizes of the limiting hole 11312 and the connecting hole 1231. Thus, the head 1311 of the pin 131 can pass smoothly through the through hole 11311, and the head 1311 of the pin 131 can abut against the outer periphery of the limiting hole 11312 near the mounting groove 1101 to form a limiting fit. Similarly, the pressing member 132 can abut against the outer periphery of the connecting hole 1231 near the operating member 133 to form a limiting fit.

[0068] In actual execution, when installing the frame body 11 and the pressure block 12, firstly, the rod portion 1312 of the pin 131 of the pre-installed fastener 13 is passed through the connecting hole 1231 of the pressure block 12, so that the head 1311 of the pressing member 132 and the pin 131 are respectively located on both sides of the connecting hole 1231, thus completing the pre-installation of the fastener 13 and the pressure block 12. Subsequently, the pre-installed fastener 13 and pressure block 12 assembly is installed on the frame body 11. Specifically, the pressure block 12 is nested outside the frame body 11, so that the head 1311 of the pin 131 of the fastener 13 passes through the through hole 11311 of the frame body 11. At this time, the head 1311 of the pin 131 is located on the side of the through hole 11311 near the mounting groove 1101, and the rod portion 1312 passes through the through hole 11311. Next, the fastener 13 and the pressure block 12 assembly is moved from the position of the through hole 11311 to the position of the limiting hole 11312, so that the rod portion 1312 of the pin 131 passes through the connecting hole 1231 and the limiting hole 11312 in sequence. Finally, the operating member 133 is turned to drive the operating member 133 to rotate around the hinge point until the pressing member 132 is pressed, thereby firmly clamping the pressure block 12 and the frame body 11 between the pressing member 132 and the head 1311 of the pin 131, completing the installation.

[0069] When disassembling the frame body 11 and the pressure block 12, the operating member 133 is reversed and rotated around the hinge point to release the pressure member 132, thereby relieving the clamping force on the pressure block 12 and the frame body 11. Then, the fastener 13 and the pressure block 12 assembly is moved from the position of the limiting hole 11312 to the position of the through hole 11311. Finally, the pin 131 is pulled out of the frame body 11 through the through hole 11311 to complete the disassembly.

[0070] The component frame 10 provided in this application embodiment, through the above-mentioned through holes 11311 and limiting holes 11312, provides structural support for the fastener 13 to be directly inserted and assembled into the frame body 11 as an integrated pre-assembled component. There is no need to prepare many independent parts for on-site assembly. The fastener 13 is a pre-assembled integral component, which reduces the number of parts used, thereby saving the cost of material procurement, management and storage, and reducing the probability of part loss and mismatch.

[0071] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the assembly part 1131 also includes a channel 11313, which is connected between the through hole 11311 and the limiting hole 11312, and the rod part 1312 is adapted to slide with the channel 11313.

[0072] In this embodiment, such as Figure 1 , Figure 2 and Figure 5As shown, the through hole 11311 and the channel 11313 are integral elongated holes, and the limiting hole 11312 can be a circular hole. The end of the integral elongated hole opposite to the limiting hole 11312 has an arc segment, which forms at least part of the boundary of the through hole 11311. The end of the integral elongated hole connected to the limiting hole 11312 can be a bent connection or a smooth arc transition connection, thereby forming a complete path from the through hole 11311 to the limiting hole 11312. The position of the channel 11313 corresponds to the axis of the through hole 11311 and the limiting hole 11312, so that the rod portion 1312 of the pin 131 can slide smoothly along the channel 11313, realizing the switching of the fastener 13 from the position of passing through the through hole 11311 to the position of being fixed in the limiting hole 11312. The channel 11313 serves as a sliding track for the rod 1312 of the pin 131, guiding and constraining the rod 1312 to prevent it from shifting or wobbling during movement. It also reduces direct friction between the rod 1312 and the frame body 11, maintaining stability during installation. Specifically, the dimensions of the channel 11313 can be adapted to the rod 1312 of the pin 131, allowing the rod 1312 to move freely along the length of the channel 11313 while limiting its radial displacement, thus maintaining the accuracy of the rod 1312's movement trajectory.

[0073] In other embodiments, the through hole 11311 and the limiting hole 11312 can be circular holes, and the channel 11313 can be an elongated hole-like structure formed between the through hole 11311 and the limiting hole 11312. Among them, channel 11313 is, but is not limited to, a straight channel, a curved channel, or a broken line channel, etc., and the embodiments of this application do not limit it.

[0074] The component frame 10 provided in this application embodiment, through the aforementioned provision of the channel 11313 connecting the through hole 11311 and the limiting hole 11312, extends the movement path of the fastener 13 between the through hole 11311 and the limiting hole 11312 during installation and disassembly. This significantly reduces the risk of the fastener 13 accidentally sliding back into the through hole 11311 and falling off due to the excessive proximity of the through hole 11311 and the limiting hole 11312 when subjected to slight disturbance. Combined with the dimensional constraints of the limiting hole 11312, this further enhances the strength and reliability of the fastener 13 connection.

[0075] In some embodiments, such as Figure 1 , Figure 2 and Figures 5-7As shown, the border body 11 comprises a plurality of side beams 11a connected end to end in sequence, each side beam 11a comprises a beam top plate 111, a beam side plate 112 and a beam bottom plate 113 connected in sequence, the pressing block 12 comprises a first plate 121, a second plate 122 and a third plate 123 connected by bending in sequence, the first plate 121 abuts against the beam top plate 111, the second plate 122 abuts against the beam side plate 112, and the third plate 123 is connected with the beam bottom plate 113 through a fastener 13.

[0076] As Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the border body 11 is formed by splicing a plurality of side beams 11a connected end to end in sequence through corner connectors, welding, buckles or other methods, forming a closed frame structure to provide circumferential support for the photovoltaic laminate. Each side beam 11a consists of a beam top plate 111, a beam side plate 112 and a beam bottom plate 113 connected in sequence, the three form a section similar to a "匚" shape, with the opening facing the inner side of the frame for accommodating the edge of the photovoltaic laminate. Wherein, the beam top plate 111 is located at the top of the side beam 11a, configured to abut against the edge of the upper surface of the photovoltaic laminate and limit the upward displacement of the photovoltaic laminate; the beam side plate 112 is a vertical side plate connecting the beam top plate 111 and the beam bottom plate 113, forming the side main body of the side beam 11a and providing lateral support for the photovoltaic laminate; the beam bottom plate 113 is located at the bottom of the side beam 11a, serving as the main bearing structure of the assembling portion 1131, and is connected with the connecting hole 1231 of the pressing block 12 by means of the fastener 13.

[0077] As Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the pressing block 12 has a "匚"-shaped cross-section as a whole, the opening direction of which is consistent with the opening direction of the border body 11, and tight fit with the side beam 11a is achieved through multi-surface abutment. Wherein, the first plate 121 is located at the top of the pressing block 12, and transmits vertical pressure through surface contact with the beam top plate 111 to assist in fixing the photovoltaic laminate; the second plate 122 is a vertical side plate connecting the first plate 121 and the third plate 123, forming the side main body of the pressing block 12, providing lateral restraint for the beam side plate 112 and reducing relative lateral sliding between the pressing block 12 and the side beam 11a; the third plate 123 is located at the bottom of the pressing block 12, and a connecting hole 1231 is opened thereon, which is suitable for being aligned with the limiting hole 11312 of the assembling portion 1131 of the beam bottom plate 113, and the first plate 121 and the second plate 122 are respectively pressed against the beam top plate 111 and the beam side plate 112 by the clamping force of the fastener 13, so as to realize the overall fixation of the pressing block 12 and the side beam 11a.

[0078] Exemplarily, as Figure 7As shown, in order to optimize the limiting effect of the mounting groove 1101 on the edge of the photovoltaic laminate, the end of the beam top plate 111 away from the beam side plate 112 can be bent downward to form a hook shape, so as to better clamp the photovoltaic laminate. In this case, the first plate 121 can be designed to conform to the beam top plate 111 as much as possible to achieve the best fitting effect.

[0079] It should be noted that, depending on actual needs or the material characteristics of the pressure block 12, protective pads with higher friction can be added to certain areas of the contact surface between the pressure block 12 and the frame body 11 to minimize the relative slippage between the frame body 11 and the pressure block 12. These protective pads may include, but are not limited to, protective pads, protective films, or protective airbags; this embodiment does not impose any limitations on these.

[0080] The component frame 10 provided in this application embodiment abuts against the beam top plate 111 and the beam side plate 112 respectively through the first plate 121 and the second plate 122, and is connected to the beam bottom plate 113 by the third plate 123 through the fastener 13. This forms a multi-faceted contact and constraint between the frame body 11 and the pressure block 12, making the connection between the pressure block 12 and the side beam 11a more solid, effectively suppressing the bending of the side beam 11a under its own weight or wind pressure, making the photovoltaic laminate uniformly stressed, reducing the risk of microcracks, and thus improving the overall structural stability of the photovoltaic module. At the same time, after the first plate 121 abuts against the beam top plate 111 and the second plate 122 abuts against the beam side plate 112, the third plate 123 can automatically align with the beam bottom plate 113, thereby reducing the positioning and alignment time during installation.

[0081] In some embodiments, such as Figures 5-7 As shown, one of the second plate 122 and the beam side plate 112 is provided with a locking block 1221, and the other is provided with a locking groove 1121 for engaging with the locking block 1221.

[0082] In this embodiment, such as Figures 5-7 As shown, the second plate 122 is provided with a locking block 1221, and the beam side plate 112 is provided with a locking groove 1121 for engaging with the locking block 1221.

[0083] In other implementations, such as Figures 5-7 As shown, the beam side plate 112 is provided with a locking block 1221, and the second plate 122 is provided with a locking groove 1121 for engaging with the locking block 1221.

[0084] It should be noted that the mating interface between the second plate 122 and the beam side plate 112 can be designed with different styles of card blocks 1221 and corresponding card slots 1121 according to actual needs, which can increase the biting force between the frame and the pressure block 12, thereby maximizing the stability of the pressure block 12 in fixing the frame.

[0085] Specifically, the shape of the card block 1221 may include, but is not limited to, a rectangular card block, a trapezoidal card block, a wedge-shaped card block, or a barbed card block. The card slot 1121 may be designed to match the shape of the card block 1221. This application embodiment does not limit this.

[0086] The component frame 10 provided in this application embodiment, through the snap-fit ​​design of the aforementioned snap-fit ​​block 1221 and slot 1121, provides additional constraint force between the pressure block 12 and the side beam 11a on the basis of the fastener 13. When the component frame 10 is subjected to vibration, external impact, or other conditions, this snap-fit ​​structure effectively reduces the risk of the pressure block 12 loosening or shifting relative to the side beam 11a, further increasing the firmness and stability of the connection between the pressure block 12 and the frame body 11. Simultaneously, during assembly, the snap-fit ​​block 1221 and slot 1121 can provide rapid positioning. The operator only needs to bring the second plate 122 close to the beam side plate 112, align the snap-fit ​​block 1221 with the slot 1121, and gently press it to achieve initial positioning of the pressure block 12 on the side beam 11a. This greatly reduces the time spent repeatedly adjusting the position during assembly, thereby improving the accuracy and efficiency of assembly.
