Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and more specifically, to a photovoltaic module. Background Technology

[0002] Conventional photovoltaic systems often require a support bracket to be designed on the back of each fold of photovoltaic panel, meaning the number of photovoltaic panels is the same as the number of brackets. This results in a large number of brackets, which take up a lot of space when storing the photovoltaic panels, making it difficult to store them. Utility Model Content

[0003] The present invention aims to at least solve the problems of the large number of support brackets and the large area occupied by photovoltaic panels in the related technologies.

[0004] To this end, the first aspect of this utility model provides a photovoltaic module, comprising: a plurality of photovoltaic panels connected sequentially along a first direction, the plurality of photovoltaic panels including adjacent first photovoltaic panels and second photovoltaic panels; a support bracket, comprising: a first support segment and a second support segment; a first connecting shaft, the first support segment and the second support segment being connected by the first connecting shaft, the second support segment being rotatable around the first connecting shaft so that the support bracket can switch between a supported state and a retracted state, the first end of the first support segment being connected to the back of the first photovoltaic panel away from the light-receiving surface; wherein, when the support bracket is providing support, the second support segment rotates around the first connecting shaft, the first ends of the first support segment and the first ends of the second support segment are moved away from each other, and the first end of the second support segment is able to abut against the back of the second photovoltaic panel away from the light-receiving surface, forming the supported state.

[0005] In some technical solutions, optionally, when the support bracket is stored, the second support segment rotates around the first connecting shaft, and the first end of the first support segment and the first end of the second support segment are both located on the back of the first photovoltaic panel.

[0006] The photovoltaic module provided by this utility model has two support sections that can rotate and close together or unfold. When unfolded, it can support two folded photovoltaic panels at the same time, reducing the number of supports by half. During the storage process, the two support sections are set together to form a complete support, saving the area occupied by the support support and avoiding the two support sections being scattered and affecting the storage of the photovoltaic panels.

[0007] In some technical solutions, the photovoltaic module may optionally include a rotating shaft connected to the first end of the first support section, and the rotating shaft is rotatably disposed on the back of the first photovoltaic panel, with the axial direction of the rotating shaft being the same as the first direction; the first support section is rotatably connected to the back of the photovoltaic panel through the rotating shaft, so that the support bracket can be in a supported state or stored in the back of the photovoltaic panel.

[0008] In this technical solution, the first support section is rotatably connected to the back of the photovoltaic panel via a rotating shaft, enabling the support bracket to unfold and support the photovoltaic panel. It can also be stored on the back of the photovoltaic panel, saving the overall area occupied by the photovoltaic module when it is stored.

[0009] In some technical solutions, optionally, a clearance space is provided on the rotating shaft, and the photovoltaic module also includes a second connecting shaft connected to the rotating shaft and located in the clearance space. The axial direction of the second connecting shaft is the thickness direction of the first support segment. The first end of the first support segment is connected to the second connecting shaft and can rotate around the second connecting shaft within the clearance space. The first support segment can rotate around the second connecting shaft and drive the second support segment to be housed on the back of the first photovoltaic panel.

[0010] In this technical solution, by setting a second connecting shaft, the two support sections can rotate to the back of the first photovoltaic panel, that is, there is no support section on the back of the second photovoltaic panel. The space of the bracket is reduced in the middle of the multi-fold photovoltaic panel, and the cells of the middle part of the photovoltaic panel can also be prevented from being damaged by the support bracket.

[0011] In some technical solutions, the clearance space may optionally include through holes or blind slots.

[0012] In some technical solutions, the photovoltaic module may optionally include an adjustment device installed on the second photovoltaic panel. The adjustment device is provided with multiple limit adjustment holes, which are spaced apart along a first direction. The second support section can extend into different limit adjustment holes and abut against the back of the second photovoltaic panel.

[0013] In this technical solution, the second support section can extend into different limit adjustment holes to adjust the included angle between the first support section and the second support section, that is, to adjust the support point position of the first support section and the second support section, thereby adjusting the support height.

[0014] In some technical solutions, the photovoltaic module may optionally include a bushing fixed to the first photovoltaic panel, and the bushing has a mounting cavity in which the rotating shaft is rotatably mounted.

[0015] In this technical solution, the rotating shaft is fixed by a bushing, which improves the stability of the shaft. Furthermore, it facilitates the connection between the rotating shaft and the first photovoltaic panel.

[0016] In some technical solutions, the photovoltaic module may optionally include: a first fixing plate, connected to the bushing and capable of forming a first mounting groove with the bushing, wherein at least a portion of the first photovoltaic panel is disposed in the first mounting groove; and a first locking member, one end of which passes through the first fixing plate and abuts against the first photovoltaic panel to fix the first photovoltaic panel.

[0017] In this technical solution, at least a portion of the first photovoltaic panel is disposed within the first mounting groove, thereby achieving the connection between the first photovoltaic panel and the bushing. This connection method is simpler. Furthermore, one end of the first locking member passes through the first fixing plate and abuts against the first photovoltaic panel. This eliminates the need for drilling holes in the photovoltaic panel or its frame, simplifying assembly. Additionally, it allows for quick removal of the bushing from the first photovoltaic panel, thereby enabling the support bracket to be disassembled.

[0018] In some technical solutions, the photovoltaic module may optionally include a damping pad installed in the mounting cavity and located between the rotating shaft and the bushing.

[0019] In this technical solution, the damping pad serves two purposes: firstly, it reduces noise and provides sound insulation; secondly, it prevents the bushing from rotating while the shaft is rotating, thereby improving the stability of the bushing and the photovoltaic panel.

[0020] In some technical solutions, the photovoltaic module may optionally include: a first magnetic element disposed on the first support section; and a second magnetic element disposed on the second support section; wherein, when the support bracket is in a retracted state, the first magnetic element and the second magnetic element can attract each other so that the first support section and the second support section fit together.

[0021] In this technical solution, the first magnetic component and the second magnetic component enable the first support segment and the second support segment to fit together, thereby preventing the first support segment and the second support segment from separating from each other.

[0022] In some technical solutions, the photovoltaic module may optionally include foot pads, with foot pads provided at the second end of both the first support section and the second end of the second support section.

[0023] In this technical solution, the foot pads can improve the support stability of the support bracket.

[0024] In some technical solutions, the photovoltaic module may optionally include an adhesive component disposed on the back of the first photovoltaic panel. When the support bracket is in the retracted state, the adhesive component can be bonded to the surface of the first support segment and the second support segment to fix the first support segment and the second support segment to the back of the first photovoltaic panel.

[0025] In this technical solution, the connection stability of the first support segment and the second support segment on the first photovoltaic panel can be further improved by bonding the first support segment and the second support segment with adhesive.

[0026] In some technical solutions, optionally, the first support segment has a second end, and the second support segment has a second end. In the direction perpendicular to the light-receiving surface of the photovoltaic panel, when the support bracket is in the supported state, the second end of the first support segment is within the projection range of the second photovoltaic panel, and the second end of the second support segment is within the projection range of the first photovoltaic panel.

[0027] In this technical solution, when the support bracket is in a supported state, the second end of the first support segment is within the projection range of the second photovoltaic panel, and the second end of the second support segment is within the projection range of the first photovoltaic panel. This can improve the support stability of the first and second photovoltaic panels. Attached Figure Description

Detailed Implementation

[0041] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first aspect of this utility model provides a photovoltaic module 1, including a plurality of photovoltaic panels 11 arranged along a first direction and a support bracket 12. The first direction can be the length direction of the photovoltaic panels 11, that is, the unfolding direction of the photovoltaic module 1. Any two adjacent photovoltaic panels 11 are connected by a hinge shaft 117 and can rotate relative to each other around the hinge shaft 117, so that the photovoltaic module 1 can switch between a folded state and an unfolded state. The folded state is as follows: Figure 4 As shown, the unfolded state is as follows Figure 2 As shown.

[0044] The support frame includes two support sections and a first connecting shaft 122. The first support section 124 and the second support section 126 are connected by the first connecting shaft 122. The second support section 126 can rotate around the first connecting shaft 122, thereby allowing the support bracket 12 to switch between a supported state and a retracted state. The axial direction of the first connecting shaft 122 is along the thickness direction of either the first support section 124 or the second support section 126. Figure 3As shown, in the supported state, the included angle between the first support segment 124 and the second support segment 126 is greater than a first preset value, for example, greater than or equal to 90 degrees. The first support segment 124 or the second support segment 126 forms an X-shaped support structure. In the folded state, as shown... Figure 5 As shown, the included angle between the first support segment 124 and the second support segment 126 is less than the second preset value, for example, less than or equal to 5 degrees, for example, 0 degrees. That is, in the storage state, the first support segment 124 and the second support segment 126 are usually set side by side.

[0045] The first end 1244 of the first support segment 124 connects to the back of the first photovoltaic panel 112 away from the light-receiving surface 118, thereby supporting the first photovoltaic panel 112. When the support bracket 12 is in the supported state, the first end 1244 of the first support segment 124 and the first end 1264 of the second support segment 126 are far apart from each other, and the first end 1264 of the second support segment 126 can abut against the back of the second photovoltaic panel 114 away from the light-receiving surface 118, thereby supporting the second photovoltaic panel 114. The photovoltaic module 1 provided by this utility model has two support segments that can rotate and unfold relative to each other, and can simultaneously support two folded photovoltaic panels 11, reducing the number of brackets by half compared to setting one bracket for each photovoltaic panel 11. When the photovoltaic module is stored, the first end 1244 of the first support segment 124 and the first end 1264 of the second support segment 126 come into contact, that is, the two support segments are set side by side to form a straight bracket. The first end 1244 of the first support segment 124 is located on the back of the first support segment 124, which saves the overall space occupied by the support bracket 12, thus making the stored photovoltaic module 1 more flat.

[0046] It is important to emphasize here that the first end 1244 of the first support segment 124 refers to the portion of the support segment closest to one end of the first support segment 124, and not the end face. For example, the portion of the support segment within 10cm of the end face belongs to the first end 1244 of the first support segment 124. The concept of the first end 1264 of the second support segment 126 is similar. When the portion of the first support segment 124 closest to its first end and the portion of the second support segment 126 closest to its first end are in contact, the support bracket 12 is considered to be in a retracted state.

[0047] Optionally, when the two support segments of this application are deployed, the two support segments form an X-shaped structure, that is, the first ends of the two support segments support the first photovoltaic panel 112 and the second photovoltaic panel 114 respectively, and the second ends of the two support segments are in contact with the ground, thereby forming a stable support structure and improving the stability of the support.

[0048] In some embodiments, the photovoltaic module 1 may optionally include a rotating shaft 13 connected to the first end 1244 of the first support section 124, and the rotating shaft 13 is rotatably disposed on the back of the first photovoltaic panel 112, with the axial direction of the rotating shaft 13 being the same as the first direction; the first support section 124 is rotatably connected to the back of the photovoltaic panel 11 through the rotating shaft 13, so that the support bracket 12 can be in a supported state or stored in the back of the photovoltaic panel 11.

[0049] In this embodiment, the first support segment 124 is rotatably connected to the back of the photovoltaic panel 11 via a rotating shaft 13. The axis of rotation of the first support segment 124 is in the same direction as the first direction. The support segment can rotate relative to the photovoltaic panel 11, thereby being in a supporting state and supporting or storing the photovoltaic module 1 on the surface of the photovoltaic panel 11.

[0050] When the support bracket 12 is in the supported state, the first support segment 124 forms a preset angle with the photovoltaic panel 11. The larger the preset angle, the larger the tilt angle of the photovoltaic panel 11; the smaller the preset angle, the smaller the tilt angle of the photovoltaic panel 11. The tilt angle refers to the angle between the photovoltaic panel 11 and the vertical direction.

[0051] Optionally, the preset angle is greater than or equal to 30 degrees and less than or equal to 120 degrees, such as 60 degrees or 90 degrees.

[0052] The first support section 124 of this application is rotatably connected to the back of the photovoltaic panel 11 via the rotating shaft 13, so that the support bracket 12 can be unfolded to support the photovoltaic panel 11. The support bracket 12 can also be stored in the back of the photovoltaic panel 11, saving the area occupied by the support bracket 12.

[0053] In some embodiments, optionally, such as Figure 7 and Figure 8 As shown, a clearance space 132 is provided on the rotating shaft 13. The photovoltaic module 1 also includes a second connecting shaft 134, which is connected to the rotating shaft 13 and is located in the clearance space 132. The axial direction of the second connecting shaft 134 is the thickness direction of the first support section 124. The first end 1244 of the first support section 124 is connected to the second connecting shaft 134 and can rotate around the second connecting shaft 134 within the clearance space 132. The first support section 124 can rotate around the second connecting shaft 134 and drive the second support section 126 to be housed on the back of the first photovoltaic panel 112.

[0054] In this embodiment, by providing a second connecting shaft 134, the first end 1244 of the first support segment 124 can rotate around the second connecting shaft 134 within the clearance space 132, thereby being housed on the back of the first photovoltaic panel 112. Understandably, the support bracket 12 is typically X-shaped in its unfolded state, and the second end of the first support segment 124 is typically located below the second photovoltaic panel 114. When retracted, the first end 1244 of the first support segment 124 can rotate around the second connecting shaft 134 within the clearance space 132, allowing the second end of the first support segment 124 to be housed on the surface of the first photovoltaic panel 112. Figure 4 As shown, the second support section 126, driven by the first support section 124, can also be retracted to the surface of the first photovoltaic panel 112. This means there is no support section on the back of the second photovoltaic panel 114, reducing the number of support sections in the middle part of the multi-fold photovoltaic panel 11 and preventing damage to the cells of the middle photovoltaic panel 11 from the pressure of the support structure. In some disclosed support structures, typically, during retraction, one support section is located on the back of the first photovoltaic panel 112, and the other on the back of the second photovoltaic panel 114. Since the second photovoltaic panel 114 is located in the middle, its cells are easily damaged by the pressure of the support structure during retraction. Therefore, retracting both support sections to the outside of the first photovoltaic panel 112 prevents the support structure 12 from pressing against the cells of the middle photovoltaic panel 11. The clearance space 132 can be a through hole or a blind groove.

[0055] In some embodiments, optionally, such as Figure 6 As shown, the photovoltaic module 1 also includes an adjustment device 14, which is installed on the second photovoltaic panel 114. The adjustment device 14 is provided with a plurality of limit adjustment holes 142, which are spaced apart along the first direction. The second support section 126 can extend into different limit adjustment holes 142 and abut against the back of the second photovoltaic panel 114.

[0056] In this embodiment, the photovoltaic module 1 further includes an adjustment device 14, which is installed on the second photovoltaic panel 114, for example, on the frame of the second photovoltaic panel 114. The adjustment device 14 is provided with a plurality of limiting adjustment holes 142, which are spaced apart along a first direction, so that the second support segment 126 can extend into different limiting adjustment holes 142. When the second support segment 126 extends into different limiting adjustment holes 142, the included angle between the first support segment 124 and the second support segment 126 changes, thereby adjusting the support point position of the second support segment 126 and thus adjusting the support height.

[0057] Optionally, the limit adjustment hole 142 can be a strip-shaped hole or an oblong hole.

[0058] In addition, such as Figure 5 As shown, the first end 1264 of the second support section 126 is also provided with a pin structure 1262, so that the pin structure 1262 can be more easily inserted into the limit adjustment hole 142, thereby realizing the fixed support of the second support section 126.

[0059] Optionally, such as Figure 6 As shown, the photovoltaic module 1 also includes a second fixing plate 144, which is connected to the adjustment device 14. The second fixing plate 144 and the adjustment device 14 can form a second mounting groove 146. At least a portion of the second photovoltaic panel 114 is located in the second mounting groove 146. Then, the second locking member 148 passes through the second fixing plate 144 and abuts against the second photovoltaic panel 114, thereby fixing the adjustment device 14 and the second photovoltaic panel 114.

[0060] Optionally, there may be two or more limit adjustment holes 142.

[0061] In the above embodiments, optionally, as shown... Figure 9 As shown, the photovoltaic module 1 also includes a bushing 15, which is fixed on the first photovoltaic panel 112. The bushing 15 is provided with a mounting cavity 152, and the rotating shaft 13 is rotatably mounted in the mounting cavity 152.

[0062] In this embodiment, the rotating shaft 13 is fixed by the bushing 15, which improves the stability of the rotating shaft 13. On the other hand, it also facilitates the connection between the rotating shaft 13 and the first photovoltaic panel 112.

[0063] In addition, such as Figure 10 As shown, the bushing 15 can also limit the rotation angle of the first support section 124. For example, the maximum included angle between the first support section 124 and the photovoltaic panel 11 can be set to 120°, which can prevent the angle between the first support section 124 and the photovoltaic panel 11 from being too large, resulting in low support stability.

[0064] Of course, in some embodiments, a driving component can be provided to drive the rotating shaft 13 to rotate, thereby precisely controlling the rotation angle of the first support section 124, thereby precisely controlling the tilt angle of the photovoltaic panel 11 to meet various angles of sunlight.

[0065] In addition, such as Figure 9 As shown, the photovoltaic module 1 also includes a first fixing plate 162 and a first locking member 166. The first fixing plate 162 is connected to the bushing 15 and can form a first mounting groove 164 with the bushing 15. At least a portion of the first photovoltaic panel 112 is disposed in the first mounting groove 164. One end of the first locking member 166 passes through the first fixing plate 162 and abuts against the first photovoltaic panel 112 to fix the first photovoltaic panel 112.

[0066] In this embodiment, at least a portion of the first photovoltaic panel 112 is disposed within the first mounting groove 164, thereby achieving the connection between the first photovoltaic panel 112 and the bushing 15, which is a simpler connection method. Furthermore, one end of the first locking member 166 passes through the first fixing plate 162 and abuts against the first photovoltaic panel 112. This eliminates the need for drilling holes in the photovoltaic panel 112 or its frame, simplifying assembly. Additionally, it allows for quick removal of the bushing 15 from the first photovoltaic panel 112, thereby allowing the support bracket 12 to be disassembled.

[0067] In some embodiments, the photovoltaic module 1 may optionally include a damping pad 172 installed in the mounting cavity 152 and disposed between the rotating shaft 13 and the bushing 15.

[0068] In this embodiment, the damping pad 172 serves two purposes: firstly, it reduces noise and provides sound insulation; secondly, it prevents the bushing 15 from rotating while the shaft 13 rotates, thereby improving the stability of the bushing 15 and the photovoltaic panel 11.

[0069] In some embodiments, the photovoltaic module 1 may optionally include a first magnetic element 174 and a second magnetic element 176. The first magnetic element 174 is disposed on the first support section 124; the second magnetic element 176 is disposed on the second support section 126. When the support bracket 12 is in the retracted state, the first magnetic element 174 and the second magnetic element 176 are correspondingly disposed, so that they can attract each other to make the first support section 124 and the second support section 126 fit together, thereby preventing the first support section 124 and the second support section 126 from separating.

[0070] Optionally, the first magnetic element 174 is disposed near the second end of the first support segment 124. Similarly, the second magnetic element 176 is disposed near the second end of the second support segment 126, thereby improving the stability of the connection between the first support segment 124 and the second support segment 126 in the stored state.

[0071] In some embodiments, the photovoltaic module 1 may optionally include foot pads 178, and the second end 1246 of the first support segment 124 and the second end 1266 of the second support segment 126 are both provided with foot pads 178.

[0072] In this embodiment, both the second end of the first support segment 124 and the second end of the second support segment 126 are provided with foot pads 178, which can improve the support stability of the support bracket 12.

[0073] In some embodiments, the photovoltaic module 1 may optionally include an adhesive member 179 disposed on the back of the first photovoltaic panel 112. When the support bracket 12 is in a retracted state, the adhesive member 179 can be bonded to the surfaces of the first support segment 124 and the second support segment 126 to fix the first support segment 124 and the second support segment 126 to the back of the first photovoltaic panel 112. The adhesive member 179 may be Velcro or other adhesive connectors. By bonding the first support segment 124 and the second support segment 126 with the adhesive member 179, the connection stability of the first support segment 124 and the second support segment 126 on the first photovoltaic panel 112 can be further improved.

[0074] In the above embodiments, optionally, the photovoltaic module 1 further includes a reinforcing plate disposed on the back of the photovoltaic panel 11 for reinforcing the photovoltaic panel 11.

[0075] In this embodiment, a reinforcing plate is provided on the back of the photovoltaic panel 11 to strengthen the photovoltaic panel 11. The reinforcing plate can be arranged along the first direction or perpendicular to the first direction. That is, it can be arranged along the width or length of the photovoltaic panel 11. The number of reinforcing plates on the back of each photovoltaic panel 11 is set according to the actual situation, for example, it can be 1 to 3.

[0076] In the above embodiments, optionally, as shown... Figure 2 As shown, along the first direction, the plurality of photovoltaic panels 11 include third photovoltaic panels 116 located at both ends, and the third photovoltaic panels 116 are provided with handle structures 1162.

[0077] In this embodiment, handle structures 1162 are provided on the photovoltaic panels 11 at both ends to facilitate the unfolding and folding of the photovoltaic panels 11. The handle structure 1162 may be a clearance space 132 provided on the third photovoltaic panel 116 along the thickness direction of the third photovoltaic panel 116, or it may be a handle, etc.

[0078] In the above embodiments, optionally, the number of support brackets 12 is less than the number of photovoltaic panels 11.

[0079] In this embodiment, the number of support brackets 12 is less than the number of photovoltaic panels 11, yet they achieve the same supporting effect, making the structure simpler.

[0080] In the above embodiments, optionally, the support bracket 12 is X-shaped. Compared with the straight single bracket, the X-shaped bracket forms a five-point support when unfolded, and the structure is more stable and reliable.

[0081] In some embodiments, optionally, the first support segment 124 has a second end 1246, and the second support segment 126 has a second end 1266. In the direction perpendicular to the light-receiving surface 118 of the photovoltaic panel 11, when the support bracket 12 is in the supported state, the second end 1246 of the first support segment 124 is within the projection range of the second photovoltaic panel 114, and the second end 1266 of the second support segment 126 is within the projection range of the first photovoltaic panel 112. This design can improve the support stability of the first photovoltaic panel 112 and the second photovoltaic panel 114. The direction perpendicular to the light-receiving surface 118 of the photovoltaic panel 11 is also the direction perpendicular to the light-receiving surface 118 of the photovoltaic panel 11 when the photovoltaic panel 11 is unfolded.

[0082] Another embodiment of this application provides a photovoltaic module, which needs to be understood as follows:

[0083] 1. Photovoltaic panels need to be tilted at a certain angle to better receive solar radiation during operation, therefore a back support is required. Portable photovoltaic panels require frequent deployment and storage, and are used outdoors under direct sunlight. The support frame itself needs good rigidity and weather resistance, while the connection points need a certain degree of flexibility or rotatability. The support frame should be designed to be as thin and lightweight as possible for easy storage, and provide stable support without deformation over long-term use.

[0084] 2. For folding photovoltaic panels with two or more folds, due to their size and weight, it is often necessary to design a support frame on the back of each fold of the photovoltaic panel to support the photovoltaic panel during operation, so as to prevent the photovoltaic panel from collapsing or deforming during long-term operation, which would affect the storage and use efficiency of the photovoltaic panel.

[0085] This embodiment provides a photovoltaic module 1 including an X-shaped folding storage support bracket device and a photovoltaic panel 11. The X-shaped folding storage support bracket device includes an X-shaped support bracket assembly and a support bracket height adjustment mechanism, forming a stable X-shaped 5-point connection support structure.

[0086] The X-type support bracket assembly includes an X-type support bracket first body, an X-type support bracket second body, a magnet, anti-slip silicone pads 178, a main body connecting pin for the support bracket 12, a bushing 15, a rotating shaft 13 for the support bracket 12, a fixing pin for the support bracket 12, a damping washer 172, bolts, a bushing 15 fixing front cover plate, and screws.

[0087] The support bracket height adjustment mechanism includes a support bracket height adjustment fixing component, a front cover plate for the support bracket height adjustment fixing component, and screws;

[0088] When the support bracket 12 is stored, the bushing 15 and the rotating shaft 13 are combined to form a damping structure. The first body of the X-type support bracket and the second body of the X-type support bracket are fixed by magnetic attraction, and then bonded to the photovoltaic panel 11 by the bottom adhesive part 179.

[0089] When the support bracket 12 is unfolded, the bushing 15 has a limiting function. When the support bracket 12 is unfolded, it is at its maximum angle. The pin structure 1262 is inserted into the adjustment groove for fixation, forming a stable five-point connection support structure.

[0090] The beneficial effects of the photovoltaic module of this application are as follows:

[0091] 1. For multi-fold photovoltaic panels, the X-type bracket design of this application can support two fold photovoltaic panels at the same time with one bracket, reducing the number of brackets by half and eliminating the need for additional storage straps, thus saving bracket costs;

[0092] 2. Compared with a single-line support, the X-type support can form a five-point connection and support in an X shape when unfolded, making the structure more stable and reliable;

[0093] 3. When the X-shaped bracket is folded up, it becomes a straight line stored on the outside. The space between the brackets is reduced due to the multiple folds of the photovoltaic panel, making the photovoltaic panel storage flatter and simpler. It also avoids the internally encapsulated cells being squeezed by the bracket.
