Description

Photovoltaic folding panel brackets and photovoltaic folding panels Technical Field

[0001] This utility model relates to the field of new energy technology, and in particular to a photovoltaic folding plate bracket and a photovoltaic folding plate. Background Technology

[0002] Solar energy, as a clean, efficient, and inexhaustible new energy source, helps us solve global problems such as the energy crisis, the greenhouse effect, and air pollution. It has achieved widespread application and rapid development globally. Currently, portable solar panels are used in energy storage applications worldwide due to their ease of transport and high mobility. Each solar panel unit can be folded together to form a foldable package for easy carrying. Currently, commercially available foldable photovoltaic panels can be folded in both the width and length directions. After unfolding, the folded photovoltaic panels need to be assembled and snapped together to prevent the panels from collapsing under the support of brackets. Currently, photovoltaic panels are joined using clips or stress-based splicing between panels. However, clips are easily broken in collisions, and the stress between panels is easily disrupted when the panels encounter strong winds or bumps. In other words, the connection between the folded photovoltaic panels is unstable, easily leading to the collapse of the unfolded photovoltaic panel. Summary of the Invention

[0003] The main purpose of this utility model is to provide a photovoltaic folding panel bracket and a photovoltaic folding panel, which aims to enable the unfolded photovoltaic folding panel to maintain stable unfolding.

[0004] To achieve the above objectives, the present invention proposes a photovoltaic folding panel bracket, which is applied to a photovoltaic folding panel. The photovoltaic folding panel includes a first folding panel and a second folding panel that can overlap each other, comprising:

[0005] An upper support plate is disposed on the first folding plate and is movably connected to the first folding plate;

[0006] A lower support plate is disposed on the second folding plate and movably connected to the second folding plate. The upper support plate and the lower support plate are detachably connected and have a supporting state and a stored state. In the supporting state, one end of the lower support plate is connected to the second folding plate, and the other end abuts against the placement surface of the photovoltaic folding plate. One end of the upper support plate is connected to the first folding plate, and the other end is connected to the lower support plate, so that the first folding plate and the second folding plate can be unfolded relative to each other. In the stored state, the upper support plate is attached to the first folding plate, and the lower support plate is attached to the second folding plate.

[0007] In one embodiment, the lower support plate includes a fixed plate segment, a folding plate segment, and a flexible connecting belt assembly. The fixed plate segment is connected to the second folding plate, the folding plate segment is rotatably connected to the fixed plate segment, and the flexible connecting belt assembly is disposed between the folding plate segment and the second folding plate to restrict the movement of the folding plate segment in the supported state.

[0008] In one embodiment, the flexible connecting strip assembly includes a rigid strip, with the two ends of the rigid strip connected to the second folded plate and the folding plate segment, respectively.

[0009] In one embodiment, the flexible connecting strip assembly further includes an elastic strip, which, in the supported state, has elastic potential energy that causes the fixed plate segment in the supported state to automatically change to the retracted state.

[0010] In one embodiment, the folding plate segment has two wire-passing holes at one end near the fixed plate segment. One end of the elastic band is connected to the middle part of the rigid band, and the other end passes through the two wire-passing holes in sequence, extends on the side of the folding plate segment near the photovoltaic folding plate, and is connected to the folding plate segment.

[0011] In one embodiment, the end of the folding plate segment away from the fixed plate segment is provided with a first fastener, and the second folding plate is provided with a corresponding second fastener. In the stored state, the folding plate segment and the second folding plate are fastened and fixed by the first fastener and the second fastener.

[0012] In one embodiment, the upper support plate includes a first folding section, a second folding section, and a third folding section arranged sequentially. The first folding section is connected to the first folding plate, the second folding section is rotatably connected to the first folding section, and the third folding section is rotatably connected to the second folding section and is detachably connected to the lower support plate.

[0013] In one embodiment, the first folding section is located at one end of the first folding plate near the second folding plate, and in the folded state, the third folding section is located at one end of the first folding plate away from the second folding plate.

[0014] In one embodiment, a first connector is provided on the side of the lower support plate away from the photovoltaic folding plate, and a second connector is provided on the third folding section, wherein the first connector and the second connector are detachably connected.

[0015] This utility model also proposes a photovoltaic folding panel, comprising:

[0016] A first folding plate and a second folding plate, wherein the first folding plate and the second folding plate can overlap each other in a first direction, and both the first folding plate and the second folding plate include a plurality of photovoltaic panels that can be folded together in the second direction in a second direction, wherein the first direction and the second direction are intersecting.

[0017] The photovoltaic folding panel support is provided in multiple parts and is arranged at intervals along the second direction.

[0018] In the technical solution of this utility model, the upper support plate, lower support plate, and first folding plate in the supported state form a triangular bracket to stably support the unfolded first and second folding plates. Due to the stable force-bearing structure of the triangle, strong winds and bumps cannot affect the unfolding of the photovoltaic folding plate. In the folded state, the upper and lower support plates are both attached to the photovoltaic folding plate and folded inside it, effectively preventing the upper and lower support plates from falling off due to impacts. This effectively enhances the unfolding stability of the photovoltaic folding plate, allowing it to maintain an effective state of receiving light energy for a longer period. In other words, through the movable connection and detachable design of the upper and lower support plates, stability in the supported state and compactness in the folded state are achieved.

[0034] This utility model proposes a photovoltaic folding panel bracket.

[0035] Please refer to Figures 1 to 5. In one embodiment of this utility model, the photovoltaic folding panel bracket is applied to a photovoltaic folding panel, which includes a first folding panel 300 and a second folding panel 400 that can overlap each other, comprising:

[0036] The upper support plate 100 is disposed on the first folding plate 300 and is movably connected to the first folding plate 300;

[0037] The lower support plate 200 is disposed on the second folding plate 400 and is movably connected to the second folding plate 400. The upper support plate 100 and the lower support plate 200 are detachably connected and have a supporting state and a stored state. In the supporting state, one end of the lower support plate 200 is connected to the second folding plate 400, and the other end abuts against the placement surface of the photovoltaic folding plate. One end of the upper support plate 100 is connected to the first folding plate 300, and the other end is connected to the lower support plate 200, so that the first folding plate 300 and the second folding plate 400 can be unfolded relative to each other. In the stored state, the upper support plate 100 is attached to the first folding plate 300, and the lower support plate 200 is attached to the second folding plate 400.

[0038] In the technical solution of this utility model, the upper support plate 100, the lower support plate 200, and the first folding plate 300, in the supported state, enclose a triangular bracket to stably support the unfolded first folding plate 300 and the second folding plate 400. Due to the stable force-bearing structure of the triangle, strong winds and bumps cannot affect the unfolding of the photovoltaic folding plate. In the folded state, the upper support plate 100 and the lower support plate 200 are both attached to the photovoltaic folding plate and folded and stored inside the photovoltaic folding plate, effectively preventing the upper support plate 100 and the lower support plate 200 from falling off due to impacts. This effectively enhances the unfolding stability of the photovoltaic folding plate, enabling it to maintain an effective state of receiving light energy for a longer period of time. In other words, through the movable connection and detachable design of the upper support plate 100 and the lower support plate 200, stability in the supported state and compactness in the folded state are achieved.

[0039] In one embodiment, the lower support plate 200 includes a fixed plate segment 21, a folding plate segment 22, and a flexible connecting strap group 23. The fixed plate segment 21 is connected to the second folded plate 400, the folding plate segment 22 is rotatably connected to the fixed plate segment 21, and the flexible connecting strap group 23 is disposed between the folding plate segment 22 and the second folded plate 400, restricting the movement of the folding plate segment 22 in the supported state. That is, a triangular force-bearing structure is formed between the lower support plate 200, the photovoltaic connecting plate, and the placement surface to support the photovoltaic folded plate. The design of the lower support plate 200 abutting against the placement surface allows the bracket to adapt to different placement surfaces, including uneven ground or inclined surfaces. This flexibility allows the photovoltaic folded plate to be stably installed in various complex terrains, and the flexible connecting strap group 23 further enhances the stability of the structure, preventing the folding plate segment 22 from loosening or deforming due to external forces. In other embodiments, the flexible connecting strap may not be provided.

[0040] In one embodiment, the flexible connecting band assembly 23 includes a rigid band 231, with its two ends connected to the second folding plate 400 and the folding plate segment 22, respectively, providing stability for the mechanical connection. In the supported state, the rigid band 231 prevents the folding plate segment 22 from shifting or deforming due to external forces, thereby ensuring the structural stability of the entire support structure. Furthermore, the flexible connecting band assembly 23 also includes an elastic band 232. In the supported state, the elastic band 232 possesses elastic potential energy that allows the fixed plate segment 21 in the supported state to automatically change to a retracted state. The elastic band 232 stores elastic potential energy in the supported state, providing additional support force to the folding plate segment 22 and further enhancing the stability of the structure. When the bracket needs to be switched from the supported state to the retracted state, the photovoltaic folding plate is moved upward, so that the folding plate segment 22 no longer continues to abut against the placement surface. The elastic potential energy is released, causing the folding plate segment 22 to automatically change to the retracted state. This design reduces the complexity of manual operation, improves the convenience of storage, and achieves automatic reset through the release of elastic potential energy, avoiding the use of complex mechanical devices and reducing the risk of failure. The combination of rigid band 231 and elastic band 232 makes the bracket structure more compact and reduces the need for additional components. This design not only simplifies the manufacturing process but also reduces production costs. In other embodiments, only one of the rigid band 231 or elastic band 232 may be provided.

[0041] In one embodiment, the folding plate segment 22 has two wire-passing holes 221 at one end near the fixed plate segment 21. One end of the elastic band 232 is connected to the middle part of the rigid band 231, and the other end passes through the two wire-passing holes 221 in sequence, extending on the side of the folding plate segment 22 near the photovoltaic folding panel and connecting with the folding plate segment 22. The elastic band 232 possesses elastic potential energy in both the supported and retracted states. The wire-passing holes 221 effectively limit the offset or twisting of the elastic band 232 during movement, ensuring that the elastic band 232 always moves along a predetermined path, thereby improving the stability of the photovoltaic folding panel support. The wire-passing holes 221 make the stress distribution of the elastic band 232 more uniform, avoiding local stress concentration, extending the service life of the elastic band 232, and preventing the elastic band 232 from interfering or colliding with other components during movement, further improving reliability. In other embodiments, one end of the elastic band 232 may be connected to the rigid band 231, and the other end may wrap around the hole wall between the two wire-passing holes 221 and connect to the folding plate segment 22.

[0042] In one embodiment, the end of the folding plate segment 22 away from the fixed plate segment 21 is provided with a first fastener 222, and the second folding plate 400 is correspondingly provided with a second fastener 41. In the stored state, the folding plate segment 22 and the second folding plate 400 are fastened and fixed by the first fastener 222 and the second fastener 41. This effectively prevents the folding plate segment 22 from loosening or shaking due to external force or vibration during transportation or storage, ensuring the structural stability of the photovoltaic folding plate bracket, avoiding volume increase due to component loosening, and ensuring the compactness of the entire bracket. Furthermore, the connection between the rigid belt 231, the elastic belt 232, and the folding plate segment 22 is the installation point of the first fastener 222 and the folding plate segment 22, and the connection point between the rigid belt 231 and the second folding plate 400 is the installation point of the second fastener and the second connecting plate. This effectively prevents the rigid band 231 and the elastic band 232 from loosening during movement or under stress, ensuring that the rigid band 231 and the elastic band 232 remain firmly connected to the second folding plate 400, thereby improving the structural stability of the entire bracket. In other embodiments, the first fastener 222 and the second fastener 41 may not be provided.

[0043] In one embodiment, the upper support plate 100 includes a first folding section 11, a second folding section 12, and a third folding section 13 arranged sequentially. The first folding section 11 is connected to the first folding plate 300, the second folding section 12 is rotatably connected to the first folding section 11, and the third folding section 13 is rotatably connected to the second folding section 12 and detachably connected to the lower support plate 200. This multi-segment folding design allows the upper support plate 100 to provide stronger support in its supported state, ensuring the stability of the first folding plate 300 and the second folding plate 400 when unfolded, preventing swaying or tipping due to external forces or wind. In its folded state, each folding segment of the upper support plate 100 can tightly fit against the first folding plate 300, reducing space occupation. In other embodiments, the third folding section 13 may be omitted.

[0044] In one embodiment, the first folding section is located at the end of the first folding plate 300 near the second folding plate 400 in the folded state, and the third folding section 13 is located at the end of the first folding plate 300 away from the second folding plate 400. This ensures that the support point is close to the connection of the folding plates, thereby improving the stability of the overall structure, effectively reducing swaying or tilting caused by external forces or wind on the photovoltaic folding plate support, and dispersing stress to reduce stress concentration at the connection between the first folding plate 300 and the second folding plate 400, thereby improving the durability of the structure. Further, the fixing plate section 21 is located at the end of the second folding plate 400 near the first folding plate 300. In other embodiments, the first folding section may also be located at the end of the first folding plate 300 away from the second folding plate 400.

[0045] In one embodiment, a first connector 223 is provided on the side of the lower support plate 200 away from the photovoltaic folding plate, and a second connector 131 is provided on the third folding section 13. The first connector 223 and the second connector 131 are detachably connected to ensure that the upper support plate 100 and the lower support plate 200 remain firmly connected in the supported state, thereby improving the stability of the overall structure. Further, the first connector 223 and the second connector 131 are configured as a female and a male Velcro fastener. In other embodiments, the lower support plate 200 may have a connecting hole, and the third folding section 13 may have a connecting protrusion. The connecting protrusion is inserted into the connecting hole to achieve assembly between the upper support plate 100 and the lower support plate 200.

[0046] This utility model also proposes a photovoltaic folding panel, which includes a first folding plate 300, a second folding plate 400, and a photovoltaic folding panel support. The specific structure of the photovoltaic folding panel support 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. The first folding plate 300 and the second folding plate 400 can overlap each other in a first direction. Both the first folding plate 300 and the second folding plate 400 include multiple photovoltaic panels 42 that can be folded together along the second direction in a second direction. The first and second directions intersect. Multiple photovoltaic folding panel supports are provided and arranged at intervals along the second direction to support and unfold the multiple photovoltaic panels 42. Understandably, when the photovoltaic folding panel is unfolded, the photovoltaic folding panel bracket stably supports and maintains the unfolded photovoltaic folding panel. When the photovoltaic folding panel is folded and stored, it has a first folding state and a second folding state. In the first folding state, the sides that can receive sunlight are brought close together to fold, so that the upper support plate 100 and the lower support plate 200 are displayed on the outside and in a stored state, fitting against the opposite sides of the photovoltaic folding panel. In the second folding state, the photovoltaic panels 42 arranged along the second direction are folded together, and part of the upper support plate 100 and the lower support plate 200 of the photovoltaic folding panel bracket are folded into the inside of the photovoltaic folding panel to protect the upper support plate 100 and the lower support plate 200, thus completing the storage of the photovoltaic folding panel.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope 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 patent protection scope of the present utility model.
