[0002] In certain specialized applications, such as portable solar charging devices and mobile emergency power systems, photovoltaic panels require convenient installation and storage. Traditional photovoltaic mounting systems are typically fixed structures, bulky and difficult to disassemble, making them unsuitable for applications with high portability requirements. For instance, carrying large, fixed photovoltaic mounting systems is extremely inconvenient for outdoor adventures, fieldwork, or temporary energy supply, not only occupying significant space but also presenting numerous difficulties during transportation and installation. Utility Model Content

[0003] The main purpose of this utility model is to propose a folding bracket and a photovoltaic folding panel, which aims to provide a folding bracket that is easy to carry and can also provide long-term fixed support for photovoltaic panels.

[0004] To achieve the above objectives, the present invention proposes a folding bracket for photovoltaic panels. The photovoltaic panel includes a solar power generation panel and a covering frame that surrounds the periphery of the solar power generation panel. The folding bracket includes:

[0005] A first frame-type support has a hinged end that is hinged to the side frame of the covering frame and a free end that is disposed opposite to the hinged end, and the hinged end is disposed on the top of the covering frame near the top of the solar power panel.

[0006] The second frame-shaped bracket has one end hinged to the bottom edge of the covering frame;

[0007] The folding bracket has a stowed state and a supported state. In the stowed state, the first frame bracket and the second frame bracket are stacked together, the second frame bracket and the back plate of the solar panel form an accommodating space, the free end is located in the accommodating space, and the other end of the second frame bracket is connected to the upper frame of the covering frame. In the supported state, the first frame bracket and the second frame bracket are separated from each other, and the free end is connected to the second frame bracket.

[0008] In one embodiment, the folding bracket further includes a pivot connecting block and a first hinge rod. The pivot connecting block is connected to the side frame of the covering frame, and the first hinge rod passes through the pivot connecting block, the side frame of the covering frame, and the hinge end to hinge the side frame of the covering frame and the hinge end.

[0009] In one embodiment, the pivot connecting block includes a snap-fit ​​groove that snaps into the side frame of the covering frame. The side wall of the snap-fit ​​groove has an avoidance notch at one end near the second frame-type bracket. Part of the structure of the covering frame inside the snap-fit ​​groove is exposed to the outside through the avoidance notch. The first hinge rod connects the pivot connecting block, the side frame of the covering frame, and the hinge end through the avoidance notch.

[0010] In one embodiment, the rotating shaft connecting block has a plurality of screws on its side away from the snap-fit ​​groove, and the screws extend into the snap-fit ​​groove to connect the rotating shaft connecting block and the covering frame.

[0011] In one embodiment, the free end includes a supporting square rod, the tail end of which is provided with a snap-fit ​​boss, and the second frame bracket is provided with a plurality of snap-fit ​​holes. In the supported state, the snap-fit ​​boss is snapped into one of the plurality of snap-fit ​​holes.

[0012] In one embodiment, the free end is further provided with a fixing block that is hinged to the supporting square rod. The fixing block is provided with a first connecting hole, and the second frame bracket is provided with a second connecting hole near the snap-fit ​​hole. A first fastener passes through the first connecting hole and the second connecting hole to connect the fixing block and the second frame bracket.

[0013] In one embodiment, the second connection hole is located on the side of the snap-fit ​​hole away from the photovoltaic panel.

[0014] In one embodiment, the second frame bracket is provided with a slot, which is located near the bottom of the photovoltaic panel. The first frame bracket is provided with a connecting crossbar, which is located near the free end. At the storage position, the connecting crossbar is engaged with the slot.

[0015] In one embodiment, the second frame-shaped support is hinged to the bottom edge of the covering frame via a dual-axis hinge plate. The dual-axis hinge plate includes a plate body and a second hinge rod and a third hinge rod disposed on opposite sides of the plate body. One of the second hinge rod and the third hinge rod is hinged to the second frame-shaped support, and the other is hinged to the bottom edge of the covering frame.

[0016] In one embodiment, the upper frame of the covering frame is provided with a threaded hole, and the end of the second frame bracket away from the bottom frame is provided with a connecting plate. The connecting plate is rotatably connected to the second fastener. In the retracted state, the second fastener is connected to the threaded hole.

[0017] This utility model also proposes a photovoltaic folding panel, comprising:

[0018] A photovoltaic panel is provided in multiple forms and arranged along a first direction. Two adjacent photovoltaic panels are rotatably connected. Each photovoltaic panel includes a solar power generation panel and a covering frame that surrounds the periphery of the solar power generation panel.

[0019] A folding bracket is mounted on the back of the photovoltaic panel.

[0020] In this invention, the first and second frame-type supports are stacked together in their folded state, forming a compact storage space with the back panel of the solar panel. This significantly reduces the space occupied and facilitates transportation and storage. Utilizing a hinged structure, the folding support can quickly switch between a supported state and a folded state without disassembling complex components, simplifying the installation and storage process, saving time, improving operational efficiency, and meeting the high demands for convenience in outdoor adventures and fieldwork. In its supported state, the first and second frame-type brackets form a triangular support structure with the photovoltaic panel, which better supports the photovoltaic panel and resists the effects of external factors such as wind. Both the first and second frame-type brackets are designed with a frame structure, which helps to enhance wind resistance. The frame structure effectively disperses wind force, reduces local stress on the photovoltaic panel, and improves overall wind resistance. Furthermore, the symmetrical design of the frame-type brackets, combined with the hinged connection with the covering frame, can distribute uneven forces such as external oblique forces and torsional forces to multiple support points of the covering frame, avoiding stress concentration and ensuring the stability of the photovoltaic panel. The combination of the frame-type brackets and the covering frame enhances the rigidity of the bracket, allowing the photovoltaic panel to be more stably maintained at the designed angle, reducing the risk of deformation and swaying. This enables the folding bracket to support the photovoltaic panel outdoors for extended periods in its supported state, such as in gardens or on rooftops. Attached Figure Description

[0043] This utility model proposes a folding bracket.

[0044] Please see Figures 1 to 12 In one embodiment of this utility model, the folding bracket is used for a photovoltaic panel 400. The photovoltaic panel 400 includes a solar power generation panel 42 and a covering frame 41 that surrounds the periphery of the solar power generation panel 42. The folding bracket includes:

[0045] The first frame-type support 100 has a hinge end 11 that is hinged to the side frame of the covering frame 41 and a free end 12 that is disposed opposite to the hinge end 11, and the hinge end 11 is disposed on the covering frame 41 near the top of the solar power panel 42.

[0046] The second frame bracket 200 has one end hinged to the bottom edge of the covering frame 41;

[0047] The folding bracket has a stowed state and a supported state. In the stowed state, the first frame bracket 100 and the second frame bracket 200 are stacked together. The second frame bracket 200 and the back plate of the solar panel 42 form a receiving space 21. The free end 12 is located in the receiving space 21. The other end of the second frame bracket 200 is connected to the upper frame of the covering frame 41. In the supported state, the first frame bracket 100 and the second frame bracket 200 are separated from each other. The free end 12 is connected to the second frame bracket 200.

[0048] In this invention, the first frame bracket 100 and the second frame bracket 200 are stacked together in their folded state, forming a compact housing space 21 with the back panel of the solar panel 42. This significantly reduces the space occupied and facilitates transportation and storage. In the folded state, both ends of the second frame bracket 200 are connected to the photovoltaic panel 400, reducing the risk of the folded bracket falling apart due to shaking or bumps during transportation. Utilizing the hinged structure, the folded bracket can quickly switch between a supported state and a folded state without disassembling complex components, simplifying the installation and storage process, saving time, improving operational efficiency, and meeting the high requirements for convenience in outdoor adventures and field operations. In the supported state, the first frame bracket 100, the second frame bracket 200, and the photovoltaic panel 400 form a triangular support structure to better support the photovoltaic panel 400 and resist the influence of external factors such as wind. Both the first frame bracket 100 and the second frame bracket 200 are frame-shaped, which helps to enhance wind resistance. The frame structure effectively disperses wind force, reduces local stress on the photovoltaic panel 400, and improves overall wind resistance. The symmetrical design of the frame brackets, combined with the hinged connection with the covering frame 41, can distribute uneven forces such as external oblique forces and torsional forces to multiple support points of the covering frame 41, avoiding stress concentration and ensuring the stability of the photovoltaic panel 400. The combination of the frame brackets and the covering frame 41 can enhance the rigidity of the bracket, allowing the photovoltaic panel 400 to be more stably maintained at the designed angle, reducing the risk of deformation and swaying. This allows the folding bracket to support the photovoltaic panel 400 outdoors for a long time in the supported state, such as in gardens or on rooftops.

[0049] In one embodiment, the folding bracket further includes a pivot connecting block 300 and a first hinge rod 35. The pivot connecting block 300 is connected to the side frame of the covering frame 41. The first hinge rod 35 passes through the pivot connecting block 300, the side frame of the covering frame 41, and the hinge end 11 to hinge the side frame of the covering frame 41 and the hinge end 11. The first hinge rod 35 passes through three layers of parts at once, so that the side frame, the pivot connecting block 300, and the first frame bracket 100 share a common axis of rotation, and the axis position is precisely positioned by the pivot connecting block 300. The pivot connecting block 300 enables the first hinge rod 35 to be perpendicular to the side frame of the covering frame 41, avoiding assembly errors that cause the folding bracket to tilt. The first hinge rod 35 passes through both the side frame and the pivot connecting block 300, and the shear force is shared by the side frame and the connecting block, reducing deformation caused by local stress concentration on the side frame and extending the life of the covering frame 41. In other embodiments, the pivot connecting block 300 may not be provided.

[0050] In one embodiment, the pivot connecting block 300 includes a snap-fit ​​groove 31 that engages with the side frame of the covering frame 41. The side wall of the snap-fit ​​groove 31 near the second frame-type bracket 200 has a clearance notch 32. Partial structure of the covering frame 41 within the snap-fit ​​groove 31 is exposed to the outside through the clearance notch 32. The first hinge rod 35 connects the pivot connecting block 300, the side frame of the covering frame 41, and the hinge end 11 via the clearance notch 32. The snap-fit ​​groove 31 helps increase the contact area between the pivot connecting block 300 and the covering frame 41, further enhancing the effect of preventing localized stress concentration on the side frame. The opposite ends of the first hinge rod 35 are respectively provided with a nut and an external thread. The nut is hinged to the external thread to hinge the pivot connecting block 300, the covering frame 41, and the hinge end 11. The clearance notch 32 is used to avoid interference between the nut on the first hinge rod 35 and the second frame-type bracket 200 in the retracted state. Furthermore, the pivot connecting block 300 is provided with a relief groove 33 opposite to the relief notch 32. The relief groove 33 is located on the outer side wall of the pivot connecting block 300 away from the snap-fit ​​groove 31. The relief groove 33 and the relief notch 32 are used to avoid the nut on the first hinge rod 35. In other embodiments, the relief notch 32 may not be provided.

[0051] In one embodiment, the rotating shaft connecting block 300 has multiple screws 34 on its side away from the snap-fit ​​groove 31. The screws 34 extend into the snap-fit ​​groove 31 to connect the rotating shaft connecting block 300 and the covering frame 41. The screws 34 can lock the rotating shaft connecting block 300 to the side frame, forming a detachable rigid connection. The screw connection allows for later replacement of the rotating shaft connecting block 300, solving the problem of stripped aluminum alloy threads after long-term use; and the multiple screws 34 fixing method distributes the shear force between the rotating shaft connecting block 300 and the covering frame 41, helping to prevent single-point failure. If the connecting block is deformed due to violent handling during transportation, the user can replace only the small part of the rotating shaft connecting block 300 by removing the screws 34, without having to repair the entire covering frame 41. In other embodiments, the connection can also be made without screws 34.

[0052] In one embodiment, the free end 12 includes a supporting square rod 121, the tail end of which is provided with a snap-fit ​​boss 122. The second frame-type bracket 200 is provided with multiple snap-fit ​​holes 22. In the supported state, the snap-fit ​​boss 122 is snapped into one of the multiple snap-fit ​​holes 22. The multiple snap-fit ​​holes 22 correspond to different tilt angles, allowing the user to quickly adjust the tilt angle of the photovoltaic panel 400 according to latitude or season, improving power generation efficiency. The snap-fit ​​boss 122 and the hole wall of the snap-fit ​​hole 22 form a mechanical engagement, preventing slippage under wind load. In other embodiments, there may be only one snap-fit ​​hole 22.

[0053] In one embodiment, the free end 12 is further provided with a fixing block 123 hinged to the supporting square rod 121. The fixing block 123 is provided with a first connecting hole 124, and the second frame bracket 200 is provided with a second connecting hole 23 near the snap-fit ​​hole 22. The first fastener 231 passes through the first connecting hole 124 and the second connecting hole 23, connecting the fixing block 123 and the second frame bracket 200. This gives the first frame bracket 100 and the second frame bracket 200 a two-stage locking structure in the supported state. Specifically, the first fastener 231 is configured as a hand-tightening quick-release eye bolt, that is, without the use of tools, the first frame bracket 100 and the second frame bracket 200 can be quickly fixed or loosened by tightening the eye on the hand-tightening quick-release eye bolt. The connection method of the snap-fit ​​boss 122 and the snap-fit ​​hole 22 is redundant with the connection method of fixing the first frame bracket 100 and the second frame bracket 200 with the hand-tightened quick-release eye bolts. Even if the snap-fit ​​boss 122 wears, the bracket angle can still be maintained, which helps the folding bracket to support the solar panel for a long time in the outdoor environment. Moreover, the two-level locking structure helps to distribute part of the load and extend the service life of the folding bracket. Furthermore, during the process of changing from the supported state to the retracted state, the fixing block 123 rotates to the inside of the support square rod 121 and is confined in the accommodating space 21 in the retracted state, between the support square rod 121 and the back of the solar power panel 42, so as to avoid the fixing block 123 from colliding with the solar power panel 42 due to large shaking during transportation, and to prevent damage to the solar power panel 42. In other embodiments, the first connecting hole 124, the second connecting hole 23 and the first fastener 231 may not be provided.

[0054] In one embodiment, the second connecting hole 23 is located on the side of the snap-fit ​​hole 22 away from the photovoltaic panel 400. That is, the second connecting hole 23 is closer to the outer edge of the second frame bracket 200, and the quick-release eye bolt and the snap-fit ​​boss 122 form a larger lever arm to resist greater wind force or other forces that could damage the support stability of the folding bracket. Furthermore, since there is no solar panel 42 obstructing the view on the side away from the photovoltaic panel 400, the user can easily reach in and tighten the quick-release eye bolt, and the user can easily check whether the quick-release eye bolt is loose from the back of the bracket, providing convenient visual inspection. In other embodiments, the second connecting hole 23 may also be located on the side of the snap-fit ​​hole 22 closer to the photovoltaic panel 400.

[0055] In one embodiment, the second frame bracket 200 is provided with a slot 24, which is located near the bottom of the photovoltaic panel 400. The first frame bracket 100 is provided with a connecting crossbar 13, which is located near the free end 12. In the folded position, the connecting crossbar 13 is engaged with the slot 24. When folded, the slot 24 and the connecting crossbar 13 allow both the first frame bracket 100 and the second frame bracket 200 to abut against the back of the solar panel 42. Furthermore, the folded bracket is flattened in the folded state, reducing its volume. The connecting crossbar 13 is also restrained by the slot 24, which helps prevent the first frame bracket 100 from shaking during transportation. In other embodiments, the slot 24 may not be provided.

[0056] In one embodiment, the second frame-type support 200 is hinged to the bottom edge of the covering frame 41 via a dual-axis hinge plate 25. The dual-axis hinge plate 25 includes a plate body and a second hinge rod 251 and a third hinge rod 252 disposed on opposite sides of the plate body. One of the second hinge rod 251 and the third hinge rod 252 is hinged to the second frame-type support 200, and the other is hinged to the bottom edge of the covering frame 41. This decomposes the rotational motion of the second frame-type support 200 relative to the photovoltaic panel 400 into two degrees of freedom, namely rotation about the second hinge rod 251 and rotation about the third hinge rod 252. This allows the second frame-type support 200 to adapt to the terrain and be placed more stably on the placement surface of the folding support. In other embodiments, it may also be hinged only by the second hinge rod 251.

[0057] In one embodiment, the upper frame of the covering frame 41 is provided with a threaded hole, and the end of the second frame bracket 200 away from the bottom frame is provided with a connecting plate 26. The connecting plate 26 is rotatably connected to the second fastener 261. In the retracted state, the second fastener 261 is connected to the threaded hole. Specifically, the second fastener 261 is configured as a hand-tightening quick-release eye bolt to form a detachable connection structure, rigidly connecting the second frame bracket 200 to the upper frame of the covering frame 41. In other embodiments, the second frame bracket 200 in the retracted state can also be fixed to the upper frame of the covering frame 41 by a snap-fit.

[0058] This utility model also proposes a photovoltaic folding panel, which includes a photovoltaic panel 400 and a folding bracket. The specific structure of the folding bracket is as described in the above embodiments. Since this photovoltaic folding panel adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Among them, there are multiple photovoltaic panels 400, which are arranged along a first direction. Adjacent photovoltaic panels 400 are rotatably connected. The photovoltaic panel 400 includes a solar power generation panel 42 and a covering frame 41 that surrounds the periphery of the solar power generation panel 42. The folding bracket is installed on the back of the photovoltaic panel 400.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
