[0020] like Figure 1 and Figure 2 As shown, the photovoltaic module support device provided in the embodiments of this application may include multiple connecting components 20 and a photovoltaic bracket 700. Each connecting component 20 includes a first fastener 100, a second fastener 200, a first connector 300, a second connector 400, and a third connector 500. The multiple connecting components 20 are respectively disposed at the ends of the photovoltaic module, achieving multi-point stable support for the entire photovoltaic module through the multiple connecting components 20. Figure 1 As shown, the photovoltaic module 10 is typically rectangular. The photovoltaic module support device provided in the embodiments of this application may include four connecting components 20 and a photovoltaic bracket 700. The four connecting components 20 are respectively disposed at the four ends of the photovoltaic module 10 to achieve stable support for the photovoltaic module 10. The first connecting member 300 is rotatably connected to the photovoltaic bracket 700 around the first fastener 100 via a first fastener 100, so that the angle between the first connecting member 300 and the photovoltaic bracket 700 is adjustable. The first end of the second connecting member 400 is fixedly connected to the first connecting member 300, while the second end is rotatably connected to the third connecting member 500 around the second fastener via a second fastener 200, so that the angle between the second connecting member 400 and the third connecting member 500 is adjustable. The third connecting member 500 is used for fixed connection to the end of the photovoltaic module 10.

[0021] The first fastener 100 and the second fastener 200 are structural locking assembly components, mainly used to achieve detachable fixing and angle locking between the various connectors. The first connector 300 is the basic connecting component connecting the photovoltaic bracket 700, and is the bottom load-bearing connecting structure of the entire connecting assembly 20. The second connector 400 is an intermediate transition adjustment component, mainly serving to connect the first connector 300 and the third connector 500 in series, and can also cooperate with the third connector 500 to perform angle adjustment. The third connector 500 is the end assembly component supporting the photovoltaic module 10, and can directly contact the installation part of the photovoltaic module 10 to provide stable support for the photovoltaic module 10.

[0022] In terms of assembly, the first connector 300 is adjustablely connected to the photovoltaic support 700 via the first fastener 100. When the first fastener 100 is not tightened, the two can rotate relative to each other around the axis of the first fastener 100 to complete the first-level angle adjustment. The second connector 400 can adopt a differentiated connection method at both ends. One end forms a fixed linkage structure with the first connector 300, and the other end is adjustablely connected to the third connector 500 via the second fastener 200, allowing relative rotation around the axis of the second fastener 200. This facilitates the relative angle deflection between the second connector 400 and the third connector 500 to complete the second-level angle adjustment. The whole assembly can form an assembly structure in which the photovoltaic support 700, the first connector 300, the second connector 400, the third connector 500, and the photovoltaic module 10 are connected in series. All connection structures can be detachable for easy disassembly and maintenance.

[0023] The photovoltaic module support device provided in this application embodiment utilizes multiple independently adjustable connector structures to facilitate multi-degree-of-freedom adjustment. Firstly, the adjustable structure of the first connector 300 and the photovoltaic bracket 700 allows for adjustment of the base angle of the connecting component 20 relative to the photovoltaic bracket 700 in the axial direction surrounding the first fastener 100, facilitating adaptation to the tilt states of different load-bearing structures. Secondly, the adjustable structure of the second connector 400 and the third connector 500 in the axial direction surrounding the second fastener 200 allows for precise adjustment of the support point position, facilitating adaptation to the mounting hole spacing of photovoltaic modules 10 of different specifications. The multi-level adjustment structures work together to enhance the adaptability of the photovoltaic module support device under different installation conditions, enabling its widespread application in various photovoltaic installation scenarios such as rooftops, mountains, and tidal flats. Furthermore, the modular design of each component results in a simple structure, convenient assembly, avoidance of welding processes during assembly, effectively reducing assembly difficulty, and a high recyclability rate.

[0024] like Figure 2As shown, in some embodiments, the second connector 400 includes a first connecting portion 410 and a second connecting portion 420, the second connecting portion 420 including a first through hole 421. A second fastener 200 is inserted into the first through hole 421 and the third connector 500 to rotatably connect the second connecting portion 420 and the third connector 500 around the second fastener 200. A first end of the first connecting portion 410 is fixedly connected to the first connector 300, while a second end is threadedly connected to the second connecting portion 420, making the angle between the first connecting portion 410 and the second connecting portion 420 adjustable, thereby making the axial included angle between the first fastener 100 and the second fastener 200 adjustable.

[0025] The first connecting part 410 can be a fixed connection base, mainly used to establish the connection between the second connecting part 400 and the first connecting part 300, and to keep their relative positions fixed. The second connecting part 420 can be a connecting end, mainly responsible for docking and assembly with the third connecting part 500. The first through hole 421 is a reserved assembly hole for the second fastener 200 to pass through, so as to realize the hinged assembly of the second connecting part 420 and the third connecting part 500.

[0026] In terms of assembly, one end of the first connecting part 410 is fixed to the first connecting member 300 using a fixed connection method (such as clamping, welding, integral molding, etc.) without relative displacement to ensure the stability of the connection base. The other end of the first connecting part 410 is provided with a threaded engagement structure to form a threaded rotational connection with the second connecting part 420. The angle deflection between the two is achieved by relying on the threaded engagement structure, adding a third level of angle adjustment dimension.

[0027] The second connecting part 420 has a horizontally through-hole 421 at the end away from the first connecting part 410. The second fastener 200 can pass through the first through-hole 421 and the third connecting member 500, facilitating the movable hinge connection between the second connecting part 420 and the third connecting member 500. The second connecting member 400 is modularly disassembled and an adjustable structure is added, giving the second connecting member 400 independent angle adjustment capability, enriching the overall adjustment dimensions of the photovoltaic module support device.

[0028] The second connector 400 is designed as a split unit. The angle adjustment between the first connector 410 and the second connector 420 is achieved through a threaded connection. An adjustment dimension is added on the basis of the original two-level adjustment to form a three-level angle adjustment system, which is conducive to improving the precision of the angle adjustment of the photovoltaic module support device.

[0029] Specifically, the first connector 300 can be adjusted at an angle relative to the photovoltaic bracket 700 in the axial direction surrounding the first fastener 100; the second connector 400 can be adjusted at an angle relative to the third connector 500 in the axial direction surrounding the second fastener 200; by adjusting the relative angle between the first connecting part 410 and the second connecting part 420, the axial angle between the first fastener 100 and the second fastener 200 can be adjusted. When the first connector 300 of the connecting assembly 20 is connected to the photovoltaic bracket 700 and the third connector 500 is connected to the photovoltaic module 10, and the photovoltaic bracket 700 is fixed, the connecting assembly 20 can achieve a fixed angle for the photovoltaic module 10 in three dimensions, which can match photovoltaic modules 10 of different sizes and different installation angles.

[0030] like Figure 2 As shown, in some embodiments, the first connector 300 includes a first sidewall 310, a second sidewall 320, and a third sidewall 330. The first sidewall 310 includes a first mounting hole, and the third sidewall 330 includes a second mounting hole. The first sidewall 310 and the third sidewall 330 are disposed opposite to each other, and both ends of the second sidewall 320 are connected to the first sidewall 310 and the third sidewall 330, respectively. The end of the photovoltaic bracket 700 is located between the first sidewall 310 and the third sidewall 330. A first fastener 100 is inserted into the first mounting hole, the second mounting hole, and the photovoltaic bracket 700 to connect the first connector 300 to the photovoltaic bracket 700.

[0031] The first connector 300 adopts a frame structure with three side walls. The first side wall 310 and the third side wall 330 are relatively arranged (symmetrical or asymmetrical) assembly side walls, mainly used to open mounting holes and insert the first fastener 100 to achieve docking with the photovoltaic bracket 700. In some specific embodiments, the first side wall 310 and the third side wall 330 can be symmetrically arranged and parallel to each other.

[0032] The second sidewall 320 is an intermediate connecting load-bearing sidewall, mainly used to support the installation of the second connector 400 to transfer the load of the upper component. The first and second mounting holes can be through-holes or non-through-holes to provide an insertion channel for the first fastener 100, and can also serve as rotation reference holes for angle adjustment. Understandably, the first and second mounting holes can be threaded or non-threaded holes, and can be coaxial or non-coaxial. When the first and second mounting holes are non-coaxial, the number of first fasteners 100 can be two. In some specific embodiments, both the first and second mounting holes are through-holes, non-threaded.

[0033] In some specific embodiments, the first sidewall 310 and the third sidewall 330 can be arranged parallel to each other and spaced apart to form a clamping space, which can clamp the connecting end of the photovoltaic bracket 700 between the two sidewalls to improve the stability of the connection. The second sidewall 320 laterally connects the first sidewall 310 and the third sidewall 330, so that the three form an integrated U-shaped structure. The first mounting hole and the second mounting hole are correspondingly opened on the first sidewall 310 and the third sidewall 330. The first fastener 100 passes through the first mounting hole, the second mounting hole and the assembly part of the photovoltaic bracket 700, and hinges the first connector 300 to the photovoltaic bracket 700. With the fastener as the rotation axis, the angle of the first connector 300 is deflected. When the fastener is tightened, the angle between the first connector 300 and the photovoltaic bracket 700 can be fixed.

[0034] The first connector 300 is set as a three-sided enclosed frame structure, which has higher overall structural rigidity, stronger resistance to bending and deformation, and is easier to withstand the long-term self-weight load of the photovoltaic module 10, making it suitable for harsh outdoor installation environments.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the first connecting portion 410 includes a limiting portion 411, a connecting shaft 412, and a limiting nut 413. The connecting shaft 412 has threads. The connecting shaft 412 passes through the second sidewall 320. The limiting portion 411 is fixedly disposed at one end of the connecting shaft 412 near the second sidewall 320. The limiting nut 413 is threadedly connected to the connecting shaft 412, and the limiting nut 413 and the limiting portion 411 are respectively clamped on both sides of the second sidewall 320 to fix the first connecting portion 410.

[0036] The first connecting part 410 adopts a modular assembly structure. The limiting part 411 can be a fixed limiting block, mainly serving as a unilateral positioning and blocking function. The connecting shaft 412 can be a columnar load-bearing connecting component with a threaded structure on its surface, mainly used for interlocking assembly and realizing threaded transmission adjustment. The limiting nut 413 is a threaded locking accessory that can be threadedly assembled with the connecting shaft 412.

[0037] The connecting shaft 412 can penetrate vertically through the second sidewall 320 of the first connector 300, enabling the first connecting part 410 to be inserted and connected to the first connector 300. The limiting part 411 can be fixed at the end of the connecting shaft 412, fitting against the inner surface of the second sidewall 320 to form a unilateral limiting stop. The limiting nut 413 can be screwed in from the side of the connecting shaft 412 away from the limiting part 411, moving axially along the connecting shaft 412 by means of thread engagement, and finally cooperating with the limiting part 411 to form a bidirectional clamping on both sides of the second sidewall 320.

[0038] The first connecting part 410 is assembled using a double-sided clamping fixing method, which effectively avoids the loosening and deflection of the connecting shaft 412 under the influence of outdoor vibration and wind, thus improving the structural assembly firmness. The threaded connecting shaft 412, paired with a limiting nut 413, allows for flexible adjustment of the clamping force, adapting to the second sidewall 320 of different thicknesses, thereby broadening the component's compatibility range. Furthermore, this limiting clamping structure is easy to assemble and disassemble, facilitating future maintenance or recycling.

[0039] like Figure 2 As shown, in some embodiments, the third connector 500 includes a fourth sidewall 510, a fifth sidewall 520, and a sixth sidewall 530. The fourth sidewall 510 includes a third mounting hole, and the sixth sidewall 530 includes a fourth mounting hole. The fourth sidewall 510 and the sixth sidewall 530 are disposed opposite to each other, and both ends of the fifth sidewall 520 are connected to the fourth sidewall 510 and the sixth sidewall 530, respectively. The second connecting portion 420 is at least partially located between the fourth sidewall 510 and the sixth sidewall 530. The second fastener 200 is inserted into the third mounting hole, the first through hole 421, and the fourth mounting hole to rotatably connect the third connector 500 and the second connecting portion 420 around the second fastener 200.

[0040] The third connector 500 can adopt a three-sided enclosing frame structure adapted to the structure of the first connector 300. The fourth sidewall 510 and the sixth sidewall 530 are relatively arranged (symmetrical or asymmetrical), mainly used for opening mounting holes and inserting the second fastener 200. In some specific embodiments, the fourth sidewall 510 and the sixth sidewall 530 can be symmetrically arranged and parallel to each other. The fifth sidewall 520 can be a load-bearing assembly sidewall, mainly used for fitting and supporting the photovoltaic module 10. The third mounting hole and the fourth mounting hole are reserved holes on the sidewall, mainly used to cooperate with the second fastener 200 to complete the hinged assembly. It can be understood that the third mounting hole and the fourth mounting hole can be through-holes or non-through-holes, and can be threaded holes or non-threaded holes. In some specific embodiments, the third mounting hole and the fourth mounting hole are both through-holes and non-threaded holes.

[0041] In some specific embodiments, the fourth sidewall 510 and the sixth sidewall 530 are arranged parallel to each other, forming a clamping cavity in the middle. The end of the second connecting part 420 can extend into the cavity to achieve an embedded connection. The fifth sidewall 520 connects the fourth sidewall 510 and the sixth sidewall 530 laterally, forming a U-shaped load-bearing frame to ensure the structural strength of the third connecting member 500. The third mounting hole, the first through hole 421, and the fourth mounting hole are positioned in a corresponding manner to form a through assembly channel. The second fastener 200 passes through the three holes to clamp and fix the second connecting part 420 between the two sidewalls of the third connecting member 500. With the second fastener 200 as the rotation axis, the relative angle between the second connecting part 420 and the third connecting member 500 can be deflected to complete the end angle adjustment. When the fastener is tightened, the angle between the third connecting member 500 and the second connecting part 420 can be fixed.

[0042] The third connector 500 is configured as a three-sided enclosed frame structure, matching the structure of the first connector 300, making the overall structure of the connecting assembly 20 regular and symmetrical, and with balanced force. The clamping assembly method of the fourth side wall 510 and the sixth side wall 530 embeds and fixes the second connecting part 420, which helps to improve assembly accuracy.

[0043] like Figure 2 As shown, in some embodiments, the first mounting hole and the second mounting hole are coaxially arranged. The third mounting hole and the fourth mounting hole are coaxially arranged.

[0044] Coaxial arrangement means that the central axes of the two mounting holes coincide, and the hole diameters are aligned in the same direction without radial offset. The first and second mounting holes can be located on opposite sides of the first connector 300, coaxially arranged to form a straight assembly axis. The third and fourth mounting holes are located on opposite sides of the third connector 500, also coaxially arranged to form independent assembly axes.

[0045] The coaxially arranged first and second mounting holes ensure that the first fastener 100 passes straight through both holes, making the first fastener 100 the standard rotation axis for the angle adjustment of the first connector 300. The coaxially arranged third and fourth mounting holes, together with the central first through hole 421, form a coaxial hole group to ensure that the second fastener 200 is inserted straight through, serving as the axis for relative rotation between the second connector 400 and the third connector 500.

[0046] like Figure 2 As shown, in some embodiments, the connecting assembly 20 further includes a third fastener 600, and the fifth sidewall 520 includes a fifth mounting hole. The third fastener 600 extends through the fifth mounting hole to securely connect with the photovoltaic module 10.

[0047] The third fastener 600 is a locking component for assembling the photovoltaic module 10, mainly used to rigidly fix the third connector 500 to the photovoltaic module 10. The fifth mounting hole is a through mounting hole opened on the fifth side wall 520, providing an insertion channel for the third fastener 600.

[0048] The fifth mounting hole is directly opened on the bearing side wall (fifth side wall 520) of the third connector 500, and the hole can face the mounting end face of the photovoltaic module 10; the third fastener 600 can pass through the fifth mounting hole from bottom to top, directly contact and fix the mounting substrate of the photovoltaic module 10, so that the photovoltaic module 10 abuts against the surface of the fifth side wall 520.

[0049] like Figure 2 As shown, in some embodiments, the first fastener 100, the second fastener 200 and the third fastener 600 all include bolts and nuts.

[0050] Bolts are cylindrical, through-hole connectors with a shank and a threaded end. They are mainly used to pass through mounting holes in various components to build a connection base. Nuts are threaded locking accessories that can be tightened in conjunction with bolts to clamp and fix components together.

[0051] The first fastener 100 uses a combination of bolt and nut. The bolt passes through the first connector 300 and the photovoltaic bracket 700, and the nut is tightened at the end of the bolt to achieve hinged locking. The second fastener 200 can use the same bolt and nut combination structure. The bolt passes through the hole in the third connector 500 and the second connecting part 420, and the nut and bolt are screwed together to complete the hinged fixation. The bolt and nut can be standard universal connectors with consistent disassembly and assembly methods. Loosening the nut allows the component to rotate at an angle, and tightening the nut locks the current angle, resulting in a simple and uniform assembly structure. The bolt in the third fastener 600 passes through the fifth mounting hole and the corresponding mounting hole on the frame of the photovoltaic module 10 and is tightened with the nut to achieve a stable connection between the photovoltaic module 10 and the connecting component 20. In some specific embodiments, the photovoltaic module 10 may also include a clamping member that can clamp onto the frame of the photovoltaic module 10, and the clamping member may have mounting holes. The bolt in the third fastener 600 can pass through the fifth mounting hole and the assembly hole on the clamping member and be tightened with a nut to achieve a stable connection between the photovoltaic module 10 and the connecting component 20.

[0052] like Figure 1 and Figure 3 As shown, the photovoltaic support 700 includes a support body 710 and several support members 720. The support body 710 is used for fixed installation on a load-bearing structure, and the several support members 720 are connected to the support body 710. The support device for each photovoltaic module is connected to the end of the corresponding support member 720.

[0053] The photovoltaic bracket 700 serves as the basic load-bearing frame for supporting photovoltaic modules. The load-bearing structure can be an installation base such as the ground, roof, or platform. The support body 710 acts as a fixed base for the photovoltaic bracket 700, bearing the load of the entire device and ensuring the stability of the photovoltaic bracket 700 installation. In some specific embodiments, the support body 710 is generally columnar. The support member 720 is a support structure extending from the support body 710, primarily used to support the photovoltaic module 10. In some specific embodiments, the support member 720 can be a rod-shaped structure. The connecting component 20 is an angle-adjustable adapter assembly structure that can connect the support member 720 to the photovoltaic module 10.

[0054] The support body 710 can be fixed to the load-bearing structure by means of expansion bolts, forming a stable installation base. The first end of each support member 720 can be fixed to the support body 710, and the second end can extend outward to form an independent support point. The second end of each support member 720 can be individually connected to a connecting component 20 to achieve one-to-one matching assembly. Each connecting component 20 is independent of each other and does not interfere with each other.

[0055] In some specific embodiments, four support members 720 may be provided, including a first support member, a second support member, a third support member, and a fourth support member. The first and second support members may be fixed to the lower part of the support body 710, and the third and fourth support members may be fixed to the upper part of the support body 710. The first and second support members may extend towards the first side of the support body 710, and the third and fourth support members may extend towards the second side of the support body 710, so as to evenly distribute the load on both sides of the support body 710, facilitate the maintenance of the stability of the support body 710, and effectively improve the wind resistance and torsional resistance. The line connecting the top ends of the four support members 720 may roughly form a rectangle to provide stable four-point support for the photovoltaic module 10.

[0056] Understandably, after the photovoltaic module 10 is fixedly installed with four sets of roughly rectangularly distributed connecting components 20, the degrees of freedom between the first connecting portion 410 and the second connecting portion 420 in each connecting component 20 are constrained due to the limiting effect of the four connection positions. That is, the first connecting portion 410 and the second connecting portion 420 in each connecting component 20 cannot rotate relative to each other. Through the limiting effect of the four connection positions, there is no need to add additional locking auxiliary components, which simplifies the structure while effectively ensuring the stability of the overall structure.

[0057] like Figure 1 and Figure 3 As shown, in some embodiments, the support body 710 includes a plurality of insertion tubes 715, each insertion tube 715 being inserted and assembled with a corresponding support member 720.

[0058] The insertion tube 715 can be a pre-reserved tubular insertion port on the support body 710. It can be a hollow tubular structure with a smooth inner wall for insertion and positioning. The support member 720 is elongated. The part of the support member 720 that connects to the insertion tube 715 is the first connecting segment, and the part of the support member 720 that connects to the connecting assembly 20 is the second connecting segment. The first connecting segment can match the inner diameter of the insertion tube 715. In some specific embodiments, the cross-section of the first connecting segment and the insertion tube 715 can be rectangular, and the cross-section of the second connecting segment can be circular.

[0059] The end of the support member 720 can be directly inserted into the connector 715 to achieve a nested mating fit. After mating, fasteners can be used to lock it in place, preventing the support member 720 from slipping out of the connector 715. The mating assembly method is a physical splicing structure without welding or adhesive. The support body 710 and the support member 720 can be stored and transported separately, and can be directly aligned and mated during assembly. The mating fit between the support member 720 and the connector 715, along with the fastener locking mechanism, facilitates precise alignment and stable connection between the support member 720 and the connector 715.

[0060] The main support 710 and the support component 720 are connected by a plug-in assembly method, which makes the assembly process simple and quick, requiring no professional welding equipment or technicians, effectively shortening the assembly period on the construction site. The disassembled structure facilitates transportation and storage, resulting in lower transportation costs. Furthermore, it can be quickly disassembled and reused during later equipment relocation and modification. The components are fully recyclable, making it energy-saving, environmentally friendly, and economically excellent.

[0061] like Figure 3 As shown, in some embodiments, the support body 710 may include a first main body portion 711, a second main body portion 712, a third main body portion 713, and a fourth main body portion 714. These four portions can be sequentially inserted and engaged, and can be locked in place by fasteners to form a columnar structure. Four insertion tubes 715 may be provided, namely a first insertion tube, a second insertion tube, a third insertion tube, and a fourth insertion tube. The first and second insertion tubes can be fixed to the second main body portion 712, and the third and fourth insertion tubes can be fixed to the fourth main body portion 714. The four insertion tubes 715 can be inserted and engaged with the four support members 720 respectively, and locked in place by fasteners. In some specific embodiments, the first and second insertion tubes can be integrally formed with the second main body portion 712, and the third and fourth insertion tubes can be integrally formed with the fourth main body portion 714.

[0062] In some specific embodiments, all components of the photovoltaic module support device can be treated with a zinc-aluminum-magnesium alloy coating, which is suitable for coastal, high-humidity or industrial corrosive environments.

[0063] In some specific implementations, the specific installation steps of the photovoltaic module support device can be as follows: The first main body 711 is fixed to the load-bearing structure on site using expansion bolts; The second main body 712 (with two fixed insertion tubes 715) is inserted into the top of the first main body 711, and bolts are inserted and nuts are tightened to fix it. The lower end of the third main body 713 is inserted into the upper end of the second main body 712, and a bolt is inserted and a nut is tightened to fix it. Insert one end of each of the two support members 720 into the two insertion tubes 715 on the second main body 712 to achieve initial insertion and positioning, and then insert bolts and tighten nuts to fix them. The fourth main body 714 (with two fixed insertion tubes 715) is inserted into the top end of the third main body 713, and bolts are inserted and nuts are tightened to fix it. Insert one end of the other two support members 720 into the two insertion tubes 715 on the fourth main body 714 to achieve initial insertion and positioning, and then insert bolts and tighten nuts to fix them. A connecting component 20 is installed at the end of each support member 720 away from the support body 710. The installation steps of each connecting component 20 are as follows: insert the end of the support member 720 into the two side walls of the first connecting member 300, insert bolts, adjust the angle of the first connecting member 300, and tighten the nut to fix it; pass the connecting shaft 412 through the second side wall 320, and tighten the limiting nut 413; screw the top end of the connecting shaft 412 into the threaded hole at the bottom of the second connecting part 420; insert the top end of the second connecting part 420 into the two side walls of the third connecting member 500, insert bolts, adjust the angle of the third connecting member 500, and tighten the nut to fix it.

[0064] The four mounting holes of a photovoltaic module 10 are aligned with the fifth mounting holes of the four connecting components 20, bolts are inserted and nuts are tightened to fix them, so that the photovoltaic module support device provides stable support for the photovoltaic module 10 through four support points.

[0065] Understandably, the on-site installation of photovoltaic module support devices involves almost no welding, cutting, or drilling, which simplifies the installation process and improves the recyclability of the devices.
