Description

Technical Field

[0001] The present application belongs to the field of photovoltaic technology, and specifically relates to a mounting component, a fastening assembly and a photovoltaic system. Background Art

[0002] Solar energy, a low-carbon, renewable energy source, is easy to use, inexpensive, unaffected by climate and other factors, and poses no environmental risks, making it increasingly popular. Photovoltaic modules are used to directly convert solar energy into electricity, which can be used to power consumer devices or to transmit electricity to the grid, meeting today's energy needs. To maximize solar energy harvesting, multiple PV modules are typically assembled using mounting brackets. Aluminum or steel frames surround the PV modules to protect the laminate and connect them to the mounting brackets. Open frames are favored by the industry for their low cost and excellent load-bearing performance.

[0003] Currently, photovoltaic modules are typically installed using bolt connections. During installation, nuts are placed into the frame's cavity, and bolts are inserted from below into the holes to secure them. This mounting structure is difficult to align, making installation inconvenient. Utility Model Content

[0004] The present application aims to provide a mounting part, a fastening assembly and a photovoltaic system, which can solve the problem that the existing bolt connection structure is difficult to align holes and inconvenient to install.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In the first aspect, an embodiment of the present application proposes a mounting member for mounting a photovoltaic module with a frame having an opening, the mounting member comprising: two fixing parts, and a connecting part arranged between the two fixing parts, the connecting part connecting the two fixing parts; the fixing part is suitable for being inserted into the opening of the frame and being at least partially engaged with the frame at the opening; a through hole is provided in the fixing part, and the through hole is used to cooperate with the mounting hole in the frame to install and fix the frame.

[0007] In a second aspect, an embodiment of the present application proposes a fastening assembly, comprising: the mounting piece and a fastener as described in the first aspect, wherein the fastener is used to pass through the mounting hole in the frame and be positioned and connected with the through hole to install and fix the frame.

[0008] In a third aspect, an embodiment of the present application proposes a photovoltaic system, comprising: a photovoltaic component, a mounting base, and the fastening component described in the second aspect; the photovoltaic component has a frame, an opening is formed in the frame, the frame is placed on the mounting base, the fixing portion of the mounting member is located in the opening of the frame, the fastener passes through the mounting base and the mounting holes in the frame, and is positioned and connected with the through hole in the fixing portion.

[0009] In the embodiments of the present application, two fixing portions are provided in the mounting member so that two photovoltaic modules can be simultaneously mounted and fixed using the two fixing portions. When mounting and fixing the photovoltaic modules, the fixing portion can be inserted into the opening of the frame and at least partially engaged with the frame, thereby limiting the position of the fixing portion within the frame opening, so that the through hole in the fixing portion can be quickly and accurately aligned with the mounting hole in the frame, facilitating the installation operation. At the same time, at least partially engaging the fixing portion with the frame can also prevent loosening. In addition, compared to traditional bolt and nut mounting structures, the mounting member of the present application can increase the contact area between the mounting member and the frame, preventing damage to the frame caused by localized stress.

[0022] The following describes in detail the mounting parts, fastening components and photovoltaic systems provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a mounting member 10 according to some embodiments of the present application is used to mount a photovoltaic module having a frame 30, wherein the frame 30 has an opening 301 formed therein. The mounting member 10 includes two fixing portions 11 and a connecting portion 12 disposed between the two fixing portions 11, the connecting portion 12 connecting the two fixing portions 11. The fixing portions 11 are adapted to extend into the opening 301 of the frame 30 and engage at least partially with the frame 30 at the opening 301. A through hole 13 is provided through the fixing portion 11. Furthermore, the through hole 13 cooperates with the mounting hole 302 in the frame 30 to achieve mounting and fixing of the frame 30.

[0024] In the embodiment of the present application, two fixing portions 11 are provided in the mounting member 10 so that two photovoltaic modules can be installed and fixed at the same time by using the two fixing portions 11. When installing and fixing the photovoltaic modules, the fixing portion 11 can be inserted into the opening 301 of the frame 30, and the fixing portion 11 is at least partially engaged with the frame 30, thereby limiting the position of the fixing portion 11 in the opening 301 of the frame 30, so that the through hole 13 in the fixing portion 11 can be quickly and accurately aligned with the mounting hole 302 in the frame 30, facilitating the installation operation; at the same time, the fixing portion 11 is at least partially engaged with the frame 30, which can also prevent it from loosening. In addition, compared with the traditional bolt and nut mounting structure, the mounting member 10 of the present application can increase the contact area between the mounting member 10 and the frame 30, thereby preventing damage to the frame 30 caused by localized large stress.

[0025] Specifically, if Figure 2 As shown, the mounting member 10 in the present application can be used to install a photovoltaic module with an open frame 30. The frame 30 may include a frame body and an opening portion. The frame body is connected to and fixed to a photovoltaic laminate (not shown in the figure). The opening portion is connected to the frame body. A C-shaped opening 301 is formed in the opening portion. A mounting mating surface is provided in the opening portion for installing and fixing the frame. A mounting hole 302 is provided on the mounting mating surface for fasteners to pass through.

[0026] The mounting member 10 of the present application includes two fixing parts 11 and a connecting part 12 connected between the two fixing parts 11. Each fixing part 11 can be used to connect a frame 30. The two fixing parts 11 are connected and fixed by the connecting part 12. The connecting part 12 can play a supporting and balancing role between the two fixing parts 11 to prevent the fixing parts 11 from being skewed.

[0027] Furthermore, a through hole 13 is provided in the fixing portion 11. During installation, the fixing portion 11 is inserted into the C-shaped opening 301 of the frame 30, and the fixing portion 11 is at least partially engaged with the frame 30, so that the through hole 13 in the fixing portion 11 can correspond exactly to the position of the mounting hole 302 in the frame 30, so that fasteners 20 such as bolts can be used to pass through the mounting base 40 and the mounting hole 302 in the frame 30 in turn, and then be positioned and connected with the through hole 13 in the fixing portion 11, thereby realizing the connection and fixation between the frame 30 and the mounting base 40, so as to install the photovoltaic module on the mounting base 40.

[0028] The connection method between the mounting member 10 and the frame 30 includes, but is not limited to, a bolt connection, a pin connection, and other positioning connection structures, which are not limited in this application. In some embodiments, the hole wall of the through hole 13 can be provided with an internal thread so that a fastener with an external thread, such as a bolt, can be used to cooperate with the mounting member 10 to achieve the installation and fixation of the frame 30.

[0029] It is understood that the snap-fit structure between the fixing portion 11 and the frame 30 can be flexibly configured according to the specific structure of the frame 30. For example, when the mounting surface of the frame 30 has a protruding structure, a groove structure can be provided in the fixing portion 11 to achieve snap-fit between the two; or, when the mounting surface of the frame 30 has a recessed structure, a protruding structure can be provided in the fixing portion 11 to achieve snap-fit between the two.

[0030] Of course, other snap-in methods can be used between the fixing portion 11 and the frame 30, as long as the fixing portion 11 can be inserted into the opening 301 of the frame 30 and the fixing portion 11 and the frame 30 can be fixed in a limited position. This application does not limit this.

[0031] In some embodiments, the two fixing portions 11 in the mounting member 10 may be axially symmetrical, that is, the structures of the two fixing portions 11 are the same. Of course, the structures of the two fixing portions 11 may also be different and can be flexibly configured according to actual needs, which is not limited here.

[0032] Alternatively, as Figures 1 to 3 As shown, along the penetration direction of the through hole 13 (that is, the first direction X), the fixing portion 11 includes a first end 11a and a second end 11b that are opposite to each other, and a card slot 111 is provided on the side of the second end 11b that is opposite to the first end 11a, and the frame 30 is provided with a protrusion 303 at the opening 301, and the card slot 111 is engaged with the protrusion 303.

[0033] In an embodiment of the present application, a card slot 111 is provided at the second end 11b of the fixing portion 11, so that after the fixing portion 11 is inserted into the opening 301 of the frame 30, the card slot 111 can be engaged with the protrusion 303 at the opening 301, thereby achieving limited fixation of the fixing portion 11 and the frame 30, so that the through hole 13 in the fixing portion 11 can be quickly and accurately aligned with the installation hole 302 in the frame 30, facilitating the installation operation.

[0034] In specific applications, the frame 30 of the photovoltaic module is usually made of metal profiles. In order to increase the structural strength of the edge of the C-shaped opening 301 of the frame 30, the edge of the opening 301 is usually bent. Figure 2 and Figure 3 As shown, the side wall at the opening 301 that cooperates with the fixing portion 11 is set as a first side wall, and a mounting hole 302 is provided in the first side wall. At the same time, a bent edge is provided at the edge of the first side wall, and the bent edge forms a protrusion 303 on the first side wall. Furthermore, a slot 111 can be provided on the end surface of the second end 11b of the fixing portion 11, so that the structure of the slot 111 is compatible with the structure of the protrusion 303 on the first side wall. In this way, when the fixing portion 11 is installed in the opening 301 of the frame 30, the slot 111 in the fixing portion 11 is precisely engaged with the protrusion 303 in the frame 30, thereby limiting and fixing the fixing portion 11 in the opening 301, so that the through hole 13 in the fixing portion 11 is accurately aligned with the mounting hole 302 in the first side wall.

[0035] Specifically, the side wall of the slot 111 away from the connecting portion 12 can be brought into contact with the bent edge to limit the movement of the frame 30, thereby supporting the frame and reducing the problem of local tearing around the mounting hole when the frame is subjected to load.

[0036] It can be understood that in specific applications, the raised portion 303 at the opening 301 of the frame 30 is not limited to being formed by a bent edge. As long as a raised structure is formed on the first side wall of the frame 30, it can be used as the raised portion 303, so that the slot 111 in the fixing portion 11 is adapted to the raised portion 303 structure of the frame 30. It can be flexibly set according to actual conditions and is not limited here.

[0037] Alternatively, as Figure 2 and Figure 3 As shown, a first inclined surface 112 is provided on one side of the fixing portion 11 close to the connecting portion 12 . The first inclined surface 112 extends obliquely from the first end 11 a toward the connecting portion 12 .

[0038] In the embodiment of the present application, a first inclined surface 112 is provided on a side of the fixing portion 11 close to the connecting portion 12, so that the first inclined surface 112 extends obliquely from the first end 11a of the fixing portion 11 toward the connecting portion 12, so that the structure between the fixing portion 11 and the connecting portion 12 has a smooth transition. In this way, stress concentration caused by a structural mutation between the fixing portion 11 and the connecting portion 12 can be avoided, which helps to improve the bending resistance of the mounting member 10 at the connection between the fixing portion 11 and the connecting portion 12, thereby improving the overall strength of the mounting member 10.

[0039] Furthermore, the connecting portion 12 is connected to the second end 11 b of the fixing portion 11 . By providing the first inclined surface 112 , the size of the second end 11 b of the fixing portion 11 can be increased, thereby helping to increase the contact area between the fixing portion 11 and the frame 30 .

[0040] In some embodiments, as Figure 2 As shown, the through-hole 13 extends in the first direction X, and the angle between the first inclined surface 112 and the first direction X is 30°-70°. Specifically, the angle between the first inclined surface 112 and the first direction X can be set to 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc.

[0041] It is understandable that if the inclination angle of the first inclined surface 112 relative to the first direction X is set too small or too large, it will not serve as a structural transition between the fixing portion 11 and the connecting portion 12, and the purpose of stress dispersion will not be achieved. To this end, in this application, the angle between the first inclined surface 112 and the first direction X is set to 30°-70° to control the inclination angle of the first inclined surface 112, thereby preventing the problem of stress concentration caused by structural mutation between the fixing portion 11 and the connecting portion 12, and effectively improving the overall structural strength of the mounting member 10.

[0042] Alternatively, as Figure 2 As shown, a second inclined surface 113 is provided on a side of the fixing portion 11 away from the connecting portion 12 . The second inclined surface 113 extends obliquely from the first end 11 a toward a direction away from the connecting portion 12 .

[0043] In an embodiment of the present application, a second inclined surface 113 is provided on the side of the fixing portion 11 away from the connecting portion 12 to achieve a smooth structural transition of the side wall of the fixing portion 11 from the first end 11a to the second end 11b, thereby reducing the stress concentration problem caused by the structural mutation, helping to improve the structural strength of the fixing portion 11, and further improving the overall firmness of the installation structure when the fixing portion 11 is used to install and fix the frame 30.

[0044] In some embodiments, the through-hole 13 extends in the first direction X, and the angle between the second inclined surface 113 and the first direction X is 30°-70°. Specifically, the angle between the second inclined surface 113 and the first direction X can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc.

[0045] It is understandable that if the inclination angle of the second inclined surface 113 is too small or too large, it cannot play an effective structural transition role. For this reason, in this application, the angle between the second inclined surface 113 and the first direction X is set to 30°-70° to control the inclination angle of the second inclined surface 113, so that the second inclined surface 113 can be better utilized to prevent structural mutations.

[0046] Alternatively, as Figure 2 As shown, a guide slope 114 is further provided on one side of the fixing portion 11 away from the connecting portion 12 . The guide slope 114 extends obliquely from the second slope 113 toward the second end 11 b and the connecting portion 12 for guiding the installation of the fixing portion 11 .

[0047] In an embodiment of the present application, a guide slope 114 is provided on the side of the fixing portion 11 away from the connecting portion 12 so that when the fixing portion 11 is installed into the opening 301 of the frame 30, the guide slope 114 contacts the frame 30, thereby playing an installation guide role and facilitating the actual installation operation.

[0048] In some embodiments, as Figure 2 As shown, the through-hole 13 extends in the first direction X, and the angle between the guiding slope 114 and the first direction X is 10°-45°. Specifically, the angle between the guiding slope 114 and the first direction X can be set to 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc.

[0049] It is understandable that if the inclination angle of the guide bevel 114 is too small, it cannot play an effective guiding role. If the inclination angle of the guide bevel 114 is too large, it will be detrimental to actual processing and will cause sharp corners on the sidewalls of the fixing portion 11, which may easily damage the frame 30. For this reason, in this application, the angle between the guide bevel 114 and the first direction X is set to 10°-45°, so that the guide bevel 114 can play a guiding role during the installation of the fixing portion 11.

[0050] Alternatively, as Figure 4 As shown, the frame 30 is formed with a groove 304 at the opening 301 , and the fixing portion 11 is at least partially engaged in the groove 304 .

[0051] In the embodiment of the present application, a groove 304 is formed at the opening 301 of the frame 30. When the frame 30 is installed using the mounting member 10, the fixing portion 11 of the mounting member 10 can be extended into the opening 301, and the lower end of the fixing portion 11 can be snapped into the groove 304 to achieve limited fixation of the fixing portion 11 and the frame 30, so that the through hole 13 in the fixing portion 11 and the mounting hole 302 in the frame 30 can be accurately aligned, thereby facilitating the actual installation operation.

[0052] In a specific application, the edge portion of the frame 30 at the C-shaped opening 301 is bent to improve the strength of the frame 30 at the opening 301. Figure 4 As shown, a 90° bend is provided at the frame of the C-shaped opening 301. At this point, a groove structure is formed in the frame 30 at the position where it mates with the fixing portion 11, allowing the second end 11b of the fixing portion 11 to fit into the groove structure. Thus, when the fixing portion 11 is inserted into the opening 301 of the frame 30, the second end 11b of the fixing portion 11 precisely engages with the groove 304 in the frame 30, thereby limiting the position of the fixing portion 11 within the opening 301 of the frame 30, ensuring accurate alignment of the through hole 13 in the fixing portion 11 with the mounting hole 302 in the frame 30.

[0053] It can be understood that in specific applications, the groove 304 at the opening 301 of the frame 30 is not limited to being formed by a bent edge. As long as a recessed structure is formed at the installation and matching position of the frame 30, it can be used as the groove 304, so that the second end 11b of the fixing part 11 is adapted to the groove 304 structure of the frame 30. It can be flexibly set according to actual conditions and is not limited here.

[0054] Alternatively, as Figures 2 to 4 As shown, a step portion 14 is formed at the connection between the connecting portion 12 and the fixing portion 11 , and the step portion 14 is adapted to the edge of the mounting surface of the frame 30 .

[0055] Specifically, the frame 30 has an installation mating surface at the opening 301 that cooperates with the fixing part 11, that is, the C surface. After the frame 30 is placed on the mounting base 40, there is usually a height difference between the outer edge of the installation mating surface and the mounting surface of the mounting base 40. Then, a step portion 14 is formed at the connection between the connecting part 12 and the fixing part 11 to make the step portion 14 adapt to the outer edge structure of the installation mating surface.

[0056] In the embodiment of the present application, a step portion 14 is formed at the connection between the connecting portion 12 and the fixing portion 11. When the mounting member 10 is used to install the frame 30, the step portion 14 is adapted to the edge of the mounting mating surface of the frame 30, so that the mounting member 10 and the frame 30 can be better fitted, thereby avoiding the problem of local stress concentration. At the same time, the step portion 14 can also serve as a limiting fit between the mounting member 10 and the frame 30, thereby facilitating the assembly of the mounting member 10 and the frame 30.

[0057] Alternatively, as Figure 1 As shown, the fixing portion 11 and the connecting portion 12 are integrally formed. By setting the fixing portion 11 and the connecting portion 12 as an integrally formed part, the connection strength between the fixing portion 11 and the connecting portion 12 can be improved, and the processing and manufacturing of the entire mounting member 10 can be facilitated.

[0058] It should be noted that the mounting member 10 includes two fixing portions 11 , and the two fixing portions 11 can be provided as an integrally formed part with the connecting portion 12 , thereby helping to improve the overall structural strength of the mounting member 10 .

[0059] Alternatively, one of the fixing parts 11 and the connecting part 12 may be formed as an integral part, and the other fixing part 11 and the connecting part 12 may be a detachable structure, which is more flexible in actual use.

[0060] Alternatively, as Figures 1 to 4 As shown, along the penetrating direction of the through hole 13 , the thickness of the fixing portion 11 is greater than the thickness of the connecting portion 12 .

[0061] In the embodiment of the present application, the thickness of the fixing portion 11 is set to be greater than the thickness of the connecting portion 12 so as to improve the strength of the fixing portion 11, thereby satisfying the installation and fixing function of the frame 30 by the fixing portion 11. The connecting portion 12 is mainly used for the connection between the two fixing portions 11, and has relatively low strength requirements. The thickness of the connecting portion 12 can be reduced to reduce the production cost while satisfying the connection performance.

[0062] The above-mentioned thickness refers to the minimum thickness of the fixing portion 11 or the connecting portion 12. Specifically, along the penetration direction of the through hole 13, the minimum thickness of the fixing portion 11 can be set to 3 mm to 10 mm. For example, it can be set to any value such as 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or a range between any two values.

[0063] Alternatively, as Figures 2 to 4 As shown, an embodiment of the present application provides a fastening assembly, including: the mounting member 10 and the fastener 20 in the above embodiment, the fastener 20 is used to pass through the mounting hole 302 in the frame 30 and be positioned and connected with the through hole 13 to install and fix the frame 30.

[0064] In an embodiment of the present application, the fastening assembly includes a mounting member 10 and a fastener 20. By providing two fixing portions 11 in the mounting member 10, two photovoltaic modules can be simultaneously installed and fixed using the two fixing portions 11. When installing and fixing the photovoltaic modules, the fixing portion 11 can be inserted into the opening 301 of the frame 30, and the fixing portion 11 is at least partially engaged with the frame 30, thereby limiting the position of the fixing portion 11 in the opening 301 of the frame 30, so that the through hole 13 in the fixing portion 11 can be quickly and accurately aligned with the mounting hole 302 in the frame 30, so that the fastener 20 can be used to pass through the mounting hole 302 in the frame 30 and positionally connect with the through hole 13 to achieve the installation and fixation of the frame 30; at the same time, the fixing portion 11 is at least partially engaged with the frame 30, which can also prevent it from loosening. In addition, compared with the traditional bolt and nut installation structure, the fastening assembly of the present application can increase the contact area between the mounting member 10 and the frame 30, preventing the frame 30 from being locally damaged by large stress.

[0065] In some embodiments, the fastener 20 can be a structural member that can cooperate with the mounting member 10 to secure the frame 30. The connection between the fastener 20 and the mounting member 10 includes, but is not limited to, threaded connection, plug-in connection, and snap-on connection. Specifically, the fastener 20 can be a fastener that is at least partially provided with an external thread structure, such as a bolt, and can be flexibly configured according to actual conditions, and is not limited here.

[0066] Alternatively, as Figures 2 to 4 As shown, an embodiment of the present application provides a photovoltaic system, comprising: a photovoltaic component (only the frame 30 in the photovoltaic component is shown in the figure), a mounting base 40 and the fastening component in the above embodiment; the photovoltaic component has a frame 30, an opening 301 is formed in the frame 30, the frame 30 is placed on the mounting base 40, the fixing portion 11 of the mounting member 10 is located in the opening 301 of the frame 30, the fastener 20 passes through the mounting hole 302 in the mounting base 40 and the frame 30, and is positioned and connected with the through hole 13 in the fixing portion 11.

[0067] In an embodiment of the present application, a fastening assembly includes a mounting member 10 and a fastener 20. By providing two fixing portions 11 in the mounting member 10, two photovoltaic modules can be simultaneously installed and fixed using the two fixing portions 11. When installing and fixing the photovoltaic modules, the fixing portion 11 can be extended into the opening 301 of the frame 30, and the fixing portion 11 is at least partially engaged with the frame 30, thereby limiting the position of the fixing portion 11 in the opening 301 of the frame 30, so that the through hole 13 in the fixing portion 11 can be quickly and accurately aligned with the mounting hole 302 in the frame 30, so that the fastener 20 can be used to pass through the mounting hole 302 in the frame 30 and the mounting base 40 and then be positioned and connected with the through hole 13, thereby installing and fixing the frame 30 to the mounting base 40; at the same time, the fixing portion 11 is at least partially engaged with the frame 30, which can also prevent loosening. In addition, compared with the traditional bolt and nut mounting structure, the fastening assembly of the present application can increase the contact area between the mounting member 10 and the frame 30, preventing the frame 30 from being locally damaged by large stress.

[0068] It is understandable that the mounting base 40 can be a photovoltaic bracket, or a roof, a fixed base, or other structural member suitable for mounting and fixing photovoltaic components. It can be flexibly configured according to actual conditions and is not limited here.
