[0022] A photovoltaic (PV) module is a structure that converts solar energy into electrical energy. In related technologies, PV modules can be installed on the ground or on top of equipment using support components. These support components are typically manufactured using welding, making them impossible to disassemble and reassemble, resulting in them occupying a significant amount of space during transportation and storage. Therefore, providing a support component that facilitates transportation and storage has become a pressing technical problem for those skilled in the art. For solutions to this problem, please refer to [link to relevant documentation]. Figure 1 This application provides a support component 100 and a photovoltaic system 1000.

[0023] Please see Figures 1 to 3 The support assembly 100 of this application embodiment includes a bottom beam 10, a top beam 30, and a bracket 50. The bottom beam 10 is mounted on a bearing surface. One end of the top beam 30 is rotatably connected to the bottom beam 10, and the top beam 30 is used to mount the photovoltaic module 300. One end of the bracket 50 is rotatably connected to the bottom beam 10, and the other end is connected to the top beam 30. The connection between the bracket 50 and the bottom beam 10 is spaced apart from the connection between the bottom beam 10 and the top beam 30. The support assembly 100 has a support position (e.g., Figure 2 (as shown) and folding position (as shown) Figure 3 As shown), in the supported position, the extension directions A of the bottom beam 10, B of the top beam 30, and C of the support 50 intersect each other; in the folded position, the extension directions A of the bottom beam 10, B of the top beam 30, and C of the support 50 are parallel to each other.

[0024] The support component 100 is a structure that provides installation and support for the photovoltaic module 300, ensuring that the photovoltaic module 300 can be stably installed at a certain angle on a load-bearing surface. The load-bearing surface includes, but is not limited to, the ground, roof, and equipment surfaces. The support component 100 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. For example, the support component 100 can be made of metallic materials, such as aluminum alloy, which can improve the structural strength of the support component 100 and enhance its ability to withstand external environmental factors (such as wind, rain, and snow).

[0025] A photovoltaic module 300 is a structure capable of converting solar energy into electrical energy. The photovoltaic module 300 can be mounted on top of a support component 100 or at a specific mounting location on the support component 100. In some embodiments of this application, the photovoltaic module 300 includes at least one photovoltaic panel 310 and a frame 330. The frame 330 surrounds the outer periphery of at least one photovoltaic panel 310 and is used to mount at least one photovoltaic panel 310. The photovoltaic panel 310 is used to convert solar energy into electrical energy. The photovoltaic panel 310 can be different types of solar energy conversion devices such as monocrystalline silicon, polycrystalline silicon, or thin-film solar cells.

[0026] In some embodiments of this application, the support component 100 includes two components, which are arranged at a certain interval and jointly support the same photovoltaic module 300. On the one hand, the two support components 100 can provide multi-point support for the photovoltaic module 300, reducing the possibility of the photovoltaic module 300 tipping over and improving the stability of the photovoltaic module 300 installation. On the other hand, the two support components 100 can distribute the weight of the photovoltaic module 300 and external loads (such as wind pressure, snow load, etc.), reducing the possibility of deformation and damage to the support components 100 and ensuring the stability of the support for the photovoltaic module 300. Furthermore, the interval between the two support components 100 allows for ventilation gaps to be created for the photovoltaic module 300, which helps to reduce the operating temperature of the photovoltaic module 300 and ensure photoelectric conversion efficiency. Moreover, the gaps formed by the two support components 100 also facilitate cleaning, inspection, or replacement of the module.

[0027] In some embodiments, the photovoltaic module 300 can be detachably installed on the support assembly 100, which facilitates the removal of the photovoltaic module 300 from the support assembly 100 when maintenance or replacement is required. Detachable connection methods include, but are not limited to, snap-fit ​​and bolt connections. In other embodiments, the photovoltaic module 300 can be non-detachably installed on the support assembly 100, which improves the connection strength between the photovoltaic module 300 and the support assembly 100, ensuring the stability of the photovoltaic module 300 installed on the support assembly 100. Non-detachable connection methods include, but are not limited to, bonding or welding.

[0028] The base beam 10 is a structural component used to fix and support the entire support assembly 100. The base beam 10 can be made of materials such as steel, aluminum alloy, and concrete to ensure sufficient load-bearing capacity and stability, thereby guaranteeing the safety and reliability of the support assembly 100 during long-term use. The base beam 10 can bear only the load on the bearing surface, or it can be connected to the bearing surface using fasteners (such as bolts). The base beam 10 can be a strip structure, a column structure, a plate structure, etc. In some embodiments of this application, the base beam 10 can be a strip structure, and the cross-sectional shape of the base beam 10 (the cross-section obtained by a plane perpendicular to the extension direction A of the base beam 10) can be "U"-shaped. This ensures the contact area between the base beam 10 and the bearing surface, improving the stability of the support assembly 100 installed on the bearing surface; it also reduces the weight of the base beam 10, which is beneficial for achieving lightweighting of the support assembly 100.

[0029] The top beam 30 is a structure used to install and fix the photovoltaic module 300. The top beam 30 can be made of high-strength, corrosion-resistant materials, such as aluminum alloy, to meet the requirements of supporting the module 100 in long-term outdoor environments. The top beam 30 can be connected to the frame 330 of the photovoltaic module 300 so that the photovoltaic module 300 can be mounted on the top beam 30. The top beam 30 can be a strip structure, a column structure, a plate structure, etc. In some embodiments of this application, the top beam 30 can be a strip structure, and the cross-section of the top beam 30 (the cross-section obtained by a plane perpendicular to the extension direction B of the top beam 30) can be "U"-shaped. This ensures the connection area between the top beam 30 and the frame 330 of the photovoltaic module 300, improving connection stability; it also reduces the weight of the top beam 30, which is beneficial for achieving lightweight support of the module. Furthermore, the "U"-shaped cross-section of the top beam 30 also facilitates the complete folding of the top beam 30 towards the bottom beam 10, reducing the space occupied by the supported module 100 after folding.

[0030] In some embodiments, the top beam 30 has a fixed length (the dimension of the top beam 30 in its extension direction B). In other embodiments, the top beam 30 is a telescopic structure, for example, the top beam 30 includes at least two sub-components that are telescopically connected together, thereby allowing the user to adjust the length of the top beam 30 according to the size of the photovoltaic module 300.

[0031] The support 50 is a structure that supports the top beam 30. The support 50 can be a strip structure, a column structure, a plate structure, etc. In some embodiments of this application, the support 50 can be a strip structure, and the cross-sectional shape of the support 50 (the cross-section obtained by a plane perpendicular to the extension direction C of the support 50) can be "U"-shaped. This reduces the weight of the support 50, facilitating the lightweighting of the support assembly; it also allows for complete folding of the support 50 towards the bottom beam 10, reducing the space occupied by the folded support assembly 100.

[0032] For example, when the bracket 50 is connected to the top beam 30, the support assembly 100 is in a supporting position. In this case, the bracket 50 can support the top beam 30 so that the top beam 30 and the bottom beam 10 form a certain angle, that is, the bracket 50 can support the photovoltaic module 300 so that the photovoltaic module 300 and the bottom beam 10 form a certain angle. When the bracket 50 is disconnected from the top beam 30, the bracket 50 can rotate toward the bottom beam 10. In this case, the top beam 30 can also rotate toward the bottom beam 10, so that the support assembly 100 switches from the supporting position to the folded position. In the folded position, the extension direction C of the bracket 50, the extension direction B of the top beam 30, and the extension direction A of the bottom beam 10 are parallel to each other. That is, in the folded position, there is no angle or the angle between the top beam 30 and the bottom beam 10 is 0, which helps to reduce the space occupied by the support assembly 100 and facilitates the transportation and storage of the supports.

[0033] In some embodiments, in the folded position, the extension direction B of the top beam 30 and the extension direction A of the bottom beam 10 are substantially parallel (substantially parallel means that the two are within the allowable range of manufacturing or assembly process errors, that is, the included angle between the extension direction B of the top beam 30 and the extension direction A of the bottom beam 10 can be 0°±5°). It can be understood that, in the folded position, the extension direction C of the bracket 50 and the extension direction A of the bottom beam 10 are substantially parallel, and the extension direction C of the bracket 50 and the extension direction B of the top beam 30 are substantially parallel.

[0034] In some embodiments, the bracket 50 has a fixed length (the dimension of the bracket 50 in its extending direction C). In other embodiments, the bracket 50 is a telescopic structure, for example, the bracket 50 includes at least two sub-components that are telescopically connected together, such that a user can adjust the angle of the top beam 30 relative to the bottom beam 10 by adjusting the length of the bracket 50.

[0035] In the support component 100 of this application embodiment, in the folded position, the extension direction A of the bottom beam 10, the extension direction B of the top beam 30, and the extension direction C of the bracket 50 are parallel to each other. That is, the support component 100 can be completely folded, which can reduce the space occupied by the support component 100 and facilitate transportation and storage.

[0036] The support component 100 will be further described below with reference to the accompanying drawings.

[0037] Please see Figures 1 to 4 In some embodiments, in the folded position, the bracket 50 covers the bottom beam 10, and the top beam 30 covers the bottom beam 10 and the bracket 50.

[0038] Specifically, in some embodiments, the bottom beam 10 is provided with a first clearance groove, the top beam 30 is provided with a second clearance groove, and the support 50 is provided with a third clearance groove. In the folded position, along the width direction, the size of the second clearance groove is larger than the size of both the bottom beam 10 and the support 50, and the size of the third clearance groove is larger than the size of the bottom beam 10. Thus, in the folded position, the support 50 covers the bottom beam 10, and the top beam 30 covers both the bottom beam 10 and the support 50. That is, at least a portion of the bottom beam 10 is located within the second clearance groove, and at least a portion of the bottom beam 10 and the support 50 are located within the first clearance groove, thereby facilitating the complete folding of the support assembly 100 and reducing the space occupied by the support assembly 100. It should be noted that the extension direction A of the bottom beam 10 and the height direction H of the support assembly 100 are both perpendicular to the width direction.

[0039] In other embodiments, in the folded position, the bottom beam 10 covers the top beam 30 and the bracket 50, with the bracket 50 covering the top beam 30.

[0040] Specifically, in some embodiments, the bottom beam 10 is provided with a first clearance groove, the top beam 30 is provided with a second clearance groove, and the support 50 is provided with a third clearance groove. In the folded position, along the width direction, the size of the first clearance groove is larger than the size of the top beam 30 and also larger than the size of the support 50, while the size of the third clearance groove is larger than the size of the top beam 30. Thus, in the folded position, the bottom beam 10 covers the top beam 30 and the support 50, and the support 50 covers the top beam 30. That is, at least a portion of the top beam 30 is located within the third clearance groove, and at least a portion of the top beam 30 and the support 50 are located within the first clearance groove. This facilitates the complete folding of the support assembly 100 and reduces the space occupied by the support assembly 100. It should be noted that the extension direction A of the bottom beam 10 and the height direction H of the support assembly 100 are both perpendicular to the width direction.

[0041] For ease of understanding, the following embodiment will be described using the example of the bracket 50 covering the bottom beam 10 and the top beam 30 covering the bottom beam 10 and the bracket 50 in the folded position.

[0042] Please see Figures 2 to 4 In some embodiments, the bottom beam 10 includes a first bottom plate 11 and two second bottom plates 13, the two second bottom plates 13 being spaced apart and connected to the first bottom plate 11; the top beam 30 includes a first top plate 31 and two second top plates 33, the two second top plates 33 being spaced apart and connected to the first top plate 31; the support 50 includes a first support plate 51 and two second support plates 53, the two second support plates 53 being spaced apart and connected to the first support plate 51. The two second bottom plates 13 are respectively connected to the two second top plates 33, one end of each of the two second support plates 53 is connected to the two second bottom plates 13, and the other end of each of the two second support plates 53 is connected to the two second top plates 33.

[0043] Specifically, in some embodiments, the first base plate 11 and the two second base plates 13 can jointly form a first clearance groove; the first top plate 31 and the two second top plates 33 can jointly form a second clearance groove; and the first support plate 51 and the two second support plates 53 can jointly form a third clearance groove. The second top plate 33 is rotatably connected to the outer side of the second base plate 13 (the side of one second base plate 13 opposite to the other), one end of the second support plate 53 is rotatably connected to the outer side of the second base plate 13, and the other end of the second support plate 53 is detachably connected to the inner side of the second top plate 33 (the side of one second top plate 33 opposite to the other). Thus, when the support 50 is folded toward the bottom beam 10, the support 50 can cover the bottom beam 10; when the top beam 30 is folded toward the bottom beam 10, the top beam 30 can cover both the support 50 and the bottom beam 10.

[0044] Please combine Figure 2In some embodiments, the first support plate 51 is provided with a clearance notch 511, and part of the bottom beam 10 is located within the clearance notch 511. In this way, when the support 50 rotates relative to the bottom beam 10, the clearance notch 511 can play a clearance role, preventing the first support plate 51 from colliding with the bottom beam 10 and affecting the rotation of the support 50, and ensuring that the support assembly 100 can stably achieve folding and unfolding.

[0045] In some embodiments, the support positions include at least two, and the included angle formed by the extension direction B of the top beam 30 and the extension direction A of the bottom beam 10 is different in different support positions. The second support plate 53 is provided with a first mating part, and the second top plate 33 is provided with at least two second mating parts 331. The at least two second mating parts 331 are arranged at intervals along the extension direction B of the top beam 30. The first mating part is used to engage with any one of the at least two second mating parts 331 to allow the support assembly 100 to switch between at least two support positions.

[0046] This design allows for flexible adjustment of the photovoltaic module 300 angle to adapt to different lighting conditions, thus improving power generation efficiency. It also enhances the module's resistance to external environmental factors (such as wind, rain, and snow). For example, in windy conditions, the angle formed by the extension direction B of the top beam 30 and the extension direction A of the bottom beam 10 can be reduced to decrease the impact of wind load on the photovoltaic module 300. Similarly, in heavy snow, the angle formed by the extension direction B of the top beam 30 and the extension direction A of the bottom beam 10 can be increased to promote snow sliding and prevent snow accumulation from affecting power generation efficiency. Furthermore, it facilitates installation and maintenance; the bracket 50 can be replaced without needing to be replaced, and the support position can be quickly switched simply by aligning the first mating part with different second mating parts 331.

[0047] Specifically, in some embodiments, the first mating part can be a hole provided on the second support plate 53, and the second mating part 331 can be a hole provided on the second top plate 33. The first mating part and the second mating part 331 can be connected together by fasteners (such as bolts or pins). For example, the second top plate 33 is provided with three second mating parts 331, which are arranged at intervals along the extension direction B of the top beam 30. The first mating part can mate with any one of the three second mating parts 331 to allow the support assembly 100 to switch between three support positions. It should be noted that in other embodiments, the mating method between the first mating part and the second mating part 331 can also be magnetic mating, snap-fit ​​mating, etc., which will not be specifically explained in this application.

[0048] In some embodiments, the bottom beam 10 further includes two third bottom plates 15, which correspond to two second bottom plates 13 respectively. The third bottom plate 15 extends from the end of the corresponding second bottom plate 13 away from the first bottom plate 11 in a direction away from the other second bottom plate 13, and the third bottom plate 15 abuts against the bearing surface.

[0049] Thus, compared to the bottom beam 10 abutting against the bearing surface through the second bottom plate 13, the setting of the third bottom plate 15 can increase the contact area between the bottom beam 10 and the bearing surface, thereby improving the stability of the support component 100 installed on the bearing surface and ensuring the reliability of the support component 100 for the installation of the photovoltaic module 300.

[0050] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the support assembly 100 further includes two clamping members 70 and two fixing members 90. The two fixing members 90 are spaced apart on the top beam 30 along the extension direction B of the top beam 30 and correspond to the two clamping members 70 respectively. The fixing members 90 are used to fix the corresponding clamping members 70 to the top beam 30 so that the clamping members 70 fix the photovoltaic module 300.

[0051] Specifically, in some embodiments, two fasteners 90 and two clamping members 70 cooperate one-to-one. When the fasteners 90 fix the corresponding clamping members 70 to the top beam 30, the clamping members 70 can cooperate with the frame 330 of the photovoltaic module 300 to press the photovoltaic module 300 onto the top beam 30, thereby realizing the installation and fixation of the photovoltaic module 300 by the support component 100.

[0052] In some embodiments, the fastener 90 and the top beam 30 can be an integral structure, that is, the fastener 90 and the top beam 30 are formed as a single integral structure. This reduces the number of parts in the support assembly 100, which is beneficial to improving the assembly efficiency of the support assembly 100, reducing the user's operational burden, and improving the user experience. In other embodiments, the fastener 90 and the top beam 30 can be separate structures, that is, the fastener 90 and the top beam 30 are two independent structural components, and the fastener 90 and the top beam 30 can be combined by a detachable connection method or a non-detachable connection method. The detachable connection method includes, but is not limited to, snap-fit ​​connection or bolt connection; the non-detachable connection method includes, but is not limited to, welding or bonding.

[0053] In some embodiments, the fastener 90 includes a rivet nut. Specifically, the clamping member 70 can be bolted to the rivet nut to secure the clamping member 70 to the top beam 30. For example, the rivet nut can be pre-installed on the top beam 30 before the support assembly 100 leaves the factory. This reduces the need for reinstallation of some parts during subsequent assembly of the support assembly 100. That is, the clamping member 70 can be directly connected to the rivet nut via bolts to secure it to the top beam 30, instead of requiring bolts, washers, and nuts to be installed on the top beam 30, thus improving the assembly efficiency of the support assembly 100.

[0054] Please combine Figure 5 and Figure 6 In some embodiments, the bottom beam 10 and / or the bracket 50 are provided with clearance holes 101, into which the fastener 90 extends in the folded position. This prevents the bottom beam 10 and / or the bracket 50 from obstructing the top beam 30 when it folds towards the bottom beam 10, ensuring that the top beam 30 can be fully folded, effectively reducing the space occupied by the support assembly 100, and facilitating transportation and storage. In addition, the clearance holes 101 can also reduce the weight of the bottom beam 10 and / or the bracket 50, which is beneficial to achieving the lightweight design of the support assembly 100.

[0055] Please see Figure 1 and Figure 2 The photovoltaic system 1000 of this application includes a photovoltaic module 300 and a support component 100 of any of the above embodiments. The support component 100 is used to mount the photovoltaic module 300. It should be noted that the photovoltaic module 300 and support component 100 in this embodiment are the same as those in the above embodiments.
