Description

Technical Field

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

[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.

[0003] Several foldable photovoltaic (PV) support system designs exist in the current technology. These designs typically allow the support arms or connecting rods to be bent at hinge points, achieving a flattened or compact overall structure to reduce volume during transportation and storage. However, even if the main support structure can be folded, the support rods are often independent components or not tightly integrated with the folding structure. This means the support rods cannot be effectively enclosed or contained within the main structure after folding, resulting in a less compact overall storage volume. The support rods are easily exposed or protruding, affecting stacking and storage space efficiency. Furthermore, users often need to handle the main support structure and support rods separately, reducing the user experience. Utility Model Content

[0004] The main purpose of this utility model is to propose a folding bracket and a photovoltaic folding panel, aiming to provide a folding bracket that can be compacted and has a small volume after being stored.

[0005] To achieve the above objectives, the folding bracket proposed in this utility model includes:

[0006] The first support arm has its two ends connected to the upper and lower ends of the photovoltaic panel, respectively.

[0007] A second support arm, one end of which is hinged to one end of the first support arm;

[0008] A support rod is disposed between the first support arm and the second support arm, and the support rod has a hinged end that is hinged to one of the first support arm and the second support arm, and a free end disposed opposite to the hinged end;

[0009] The folding bracket has a stowed state and a supported state. In the stowed state, the first support arm and the second support arm overlap each other and enclose a receiving space, and the support rod is disposed in the receiving space. In the supported state, the first support arm and the second support arm are separated from each other, and the free end of the support rod abuts against the other of the first support arm and the second support arm.

[0010] In one embodiment, the second support arm is provided with a plurality of locking holes, which are arranged at intervals along the extension direction of the second support arm. In the supported state, the free end of the support rod is inserted into the locking holes.

[0011] In one embodiment, a fastening hole is provided through the second support arm in the width direction, the fastening hole being provided in correspondence with the locking hole, and a fastener passing through the fastening hole to fix the free end of the support rod to the second support arm.

[0012] In one embodiment, both the first support arm and the second support arm include a base plate and two side plates disposed on opposite sides of the base plate. The base plates of both the first support arm and the second support arm are disposed on the side of the first support arm and the second support arm that are far apart from each other. In the stored state, the base plates and the side plates of the first support arm and the second support arm can enclose the receiving space.

[0013] In one embodiment, the hinged end of the support rod is hinged to the two side plates of the first support arm.

[0014] In one embodiment, the locking hole is formed in the base plate of the second support arm, and the fastening hole is formed in the side plate of the second support arm.

[0015] In one embodiment, a first fixing member and a second fixing member are respectively provided at opposite ends of the first support arm. The first fixing member and the second fixing member are each provided with a first mounting hole at the end away from the first support arm. The upper end and the lower end of the photovoltaic panel are provided with a second mounting hole corresponding to the first mounting hole. The bolt passes through the first mounting hole and the second mounting hole to connect the photovoltaic panel with the first fixing member and the second fixing member.

[0016] In one embodiment, the first fixing member has a fixing protrusion at one end away from the photovoltaic panel. The fixing protrusion extends along the extension direction of the first support arm and protrudes from the lower edge of the first fixing member. The first fixing member has notches on both sides of the fixing protrusion in the width direction. In the retracted state, the fixing protrusion abuts against the second support arm.

[0017] In one embodiment, the second fixing member has a hinge assembly that is hinged to the second support arm on the side away from the first support arm. The hinge assembly includes a hinge plate with one end hinged to the second fixing member and the other end hinged to the second support arm.

[0018] In one embodiment, the hinged end of the support rod is located near the middle of the first support arm.

[0019] In one embodiment, bolt holes are provided at opposite ends of the second support arm.

[0020] This utility model also proposes a photovoltaic folding panel, comprising:

[0021] Multiple photovoltaic panels, which can be stacked together;

[0022] A folding bracket, wherein at least one folding bracket is provided and is installed on the back side of the photovoltaic panel.

[0023] The technical solution of this utility model significantly reduces the overall volume in the folded state by folding the first and second support arms together. This saves space compared to storing the bracket components separately or using a rigid, non-foldable bracket. When the folded bracket is in the folded state, the first and second support arms form a storage space to house the support rod, preventing the support rod from scattering, being lost, or being damaged during transportation or storage. At this time, the first and second support arms and the support rod form a compact storage structure, helping to reduce the volume of the folded bracket in the folded state. The folded bracket also has a regular shape, facilitating stacking, vehicle transport, and storage in the user's home. In the folded state, the support rod is firmly restrained within the storage space, preventing it from moving or shaking, avoiding collisions with other brackets or tools, and greatly reducing the possibility of loss during transportation or storage. Furthermore, the enclosed storage space provides a certain degree of physical protection for the internal support rod, preventing it from being deformed by compression or damaged by external impacts. The folding bracket facilitates the transition from a folded to a supported state. Users simply unfold the first and second support arms, then rotate the support rod until the free end and hinged end of the support rod abut against the first and second support arms, forming a stable triangular structure (support triangle). Due to the inherent stability of a triangle, it effectively resists wind loads, snow loads, and the weight of the solar panels themselves, ensuring the photovoltaic panels are securely installed and will not tip over. This is the core guarantee of the bracket's functionality. Attached Figure Description

[0040] This utility model proposes a folding bracket.

[0041] Please see Figures 1 to 8 In one embodiment of this utility model, the folding bracket includes:

[0042] The first support arm 11 has two ends connected to the upper and lower ends of the photovoltaic panel 200, respectively.

[0043] The second support arm 12, one end of which is hinged to one end of the first support arm 11;

[0044] The support rod 13 is disposed between the first support arm 11 and the second support arm 12, and the support rod 13 has a hinge end 131 that is hinged to one of the first support arm 11 and the second support arm 12, and a free end 132 that is disposed opposite to the hinge end 131.

[0045] The folding bracket 100 has a storage state and a support state. In the storage state, the first support arm 11 and the second support arm 12 overlap each other and enclose a receiving space 111, and the support rod 13 is disposed in the receiving space 111. In the support state, the first support arm 11 and the second support arm 12 are far apart from each other, and the free end 132 of the support rod 13 abuts against the other of the first support arm 11 and the second support arm 12.

[0046] The technical solution of this utility model significantly reduces the overall volume in the folded state by folding the first support arm 11 and the second support arm 12 together. This helps save space compared to storing the bracket components separately or using a rigid, non-foldable bracket. When the folded bracket 100 is in the folded state, the first support arm 11 and the second support arm 12 form a receiving space 111 to store the support rod 13, avoiding the risk of the support rod 13 scattering, being lost, or being crushed during transportation or storage. At this time, the first support arm 11, the second support arm 12, and the support rod 13 form a compact storage structure, which helps to reduce the volume of the folded bracket 100 in the folded state. The folded bracket 100 also has a regular shape, making it easy to stack, carry in vehicles, and store in the user's home. In the folded state, the support rod 13 is firmly restrained within the receiving space 111, preventing it from moving or shaking at will, avoiding collisions with other brackets or tools, and greatly reducing the possibility of the support rod 13 being lost during transportation or storage. Furthermore, the enclosed storage space 111 provides a certain degree of physical protection for the internal support rod 13, preventing it from being squeezed, deformed, or damaged by external impacts. The folding bracket 100 facilitates the transition from a folded state to a supported state. The user simply unfolds the first support arm 11 and the second support arm 12, and then rotates the support rod 13 until the free end 132 and the hinged end 131 of the support rod 13 abut against the first support arm 11 and the second support arm 12, forming a stable triangular structure (support triangle). Due to the inherent stability of a triangle, it can effectively resist wind loads, snow loads, and the weight of the module itself, ensuring that the photovoltaic panel 200 is firmly installed and will not tip over. This is the core guarantee of the bracket's functionality.

[0047] In one embodiment, the second support arm 12 is provided with a plurality of locking holes 121, which are spaced apart along the extension direction of the second support arm 12. In the supported state, the free end 132 of the support rod 13 is inserted into the locking hole 121. That is, the tilt angle of the photovoltaic panel 200 is correspondingly different depending on which locking hole 121 the free end 132 of the support rod 13 is inserted into, so as to adjust the support angle of the folding bracket 100 on the photovoltaic panel 200. In other embodiments, the locking holes 121 may also be provided on the first support arm 11.

[0048] In one embodiment, a fastening hole 122 is provided through the second support arm 12 in the width direction. The fastening hole 122 is correspondingly provided with a locking hole 121. A fastener 123 passes through the fastening hole 122 to fix the free end 132 of the support rod 13 to the second support arm 12. The fastener 123 and the fastening hole 122 cooperate to lock the free end 132 of the support rod 13 onto the second bracket, thereby preventing the free end 132 of the support rod 13 from slipping out of the locking hole 121 due to shaking, strong outdoor winds, or collision with other objects after the free end 132 is inserted into the locking hole 121, which helps to improve the support stability of the folding bracket 100. In other embodiments, the locking hole 121 may be omitted, and only the fastening hole 122 may be provided, or only the locking hole 121 may be provided.

[0049] In one embodiment, both the first support arm 11 and the second support arm 12 include a base plate 14 and two side plates 15 disposed on opposite sides of the base plate 14. The base plates 14 of both the first support arm 11 and the second support arm 12 are located on the sides of the first support arm 11 and the second support arm 12 that are far apart from each other. In the folded state, the base plates 14 and the side plates 15 of the first support arm 11 and the second support arm 12 can enclose a receiving space 111. Further, the width of the base plate 14 of the second support arm 12 is greater than the width of the base plate 14 of the first support arm 11. That is, in the folded state, the distance between the two base plates 14 is the width of the upper side plate 15 of the first support arm 11. This helps to further reduce the volume of the folding bracket 100 in the folded state, so as to facilitate the storage and transportation of the folding bracket 100 or the photovoltaic panel 200 having the folding bracket 100. Furthermore, the hinge end 131 of the support rod 13 is hinged to the two side plates 15 of the first support arm 11. Specifically, the hinge shaft 133 passes through the opposite side plates 15 of the first support arm 11 and the hinge end 131 of the support rod 13, so that the support rod 13 can rotate on the first support arm 11. Furthermore, the hinge end 131 of the support rod 13 is located near the middle of the first support arm 11. Furthermore, the bottom plate 14 of the first support arm 11 is provided with an observation port 112 corresponding to the hinge end 131 to facilitate maintenance and observation of the connection structure between the hinge shaft 133 and the support rod 13 and the first support arm 11. Furthermore, the locking hole 121 is formed in the bottom plate 14 of the second support arm 12, and the fastening hole 122 is formed in the side plate 15 of the second support arm 12. Furthermore, the locking hole 121 extends along the width direction of the second support arm 12 so as to have a larger contact area with the free end 132 of the support rod 13, making the support of the folding bracket 100 more stable.

[0050] In one embodiment, the first support arm 11 has a first fixing member 16 and a second fixing member 17 at opposite ends. The ends of the first fixing member 16 and the second fixing member 17 away from the first support arm 11 each have a first mounting hole 18. The upper and lower ends of the photovoltaic panel 200 have second mounting holes 21 corresponding to the first mounting holes 18. Bolts pass through the first mounting holes 18 and the second mounting holes 21 to connect the photovoltaic panel 200 to the first fixing member 16 and the second fixing member 17. This bolt connection ensures a stable connection between the folding bracket 100 and the photovoltaic panel 200. In other embodiments, the first fixing member 16 and the second fixing member 17 may have snap-fit ​​protrusions, and the photovoltaic panel 200 may have corresponding snap-fit ​​holes. During installation, simply align the second mounting hole 21 of the photovoltaic panel 200 with the first mounting hole 18 and press it into place. Disassembly is also quick and easy. This eliminates the need for screws, wrenches, and other tools, greatly improving installation efficiency, saving labor and time costs, and making the connection between the folding bracket 100 and the photovoltaic panel 200 quick and convenient.

[0051] In one embodiment, the first fixing member 16 has a fixing protrusion 161 at its end away from the photovoltaic panel 200. The fixing protrusion 161 extends along the extension direction of the first support arm 11 and protrudes from the lower edge of the first fixing member 16. The first fixing member 16 has notches 162 on both opposite sides of the fixing protrusion 161 in the width direction. In the retracted state, the fixing protrusion 161 protrudes from the first fixing member 16 and abuts against the second support arm 12 to prevent the second support arm 12 from moving away from the first support arm 11 in the retracted state. When it is necessary to change from the retracted state to the supported state, the fixing protrusion 161 can be pried away from the first support arm 11 to cause elastic deformation at the connection between the fixing protrusion 161 and the first fixing member 16, releasing the abutment against the second support arm 12 and allowing the second support arm 12 to rotate away from the first support arm 11. In other embodiments, the fixing protrusion 161 may not be provided, and the first support arm 11 and the second support arm 12 may be fixed by magnetic attraction or other means.

[0052] In one embodiment, the second fixing member 17 has a hinge assembly 171 on the side away from the first support arm 11, which is hinged to the second support arm 12. The hinge assembly 171 includes a hinge plate 172 with one end hinged to the second fixing member 17 and the other end hinged to the second support arm 12. That is, the hinge assembly 171 between the second support arm 12 and the first support arm 11 is a dual-axis hinge assembly 171, which allows the second support arm 12 to adapt to the terrain and be placed more stably on the placement surface. In other embodiments, the hinge assembly 171 may also include a hinge post that passes through the second fixing member 17 and the second support arm 12.

[0053] In one embodiment, bolt holes 124 are provided at opposite ends of the second support arm 12. Bolts pass through the bolt holes 124 to fix the folding bracket 100 to the placement surface, which helps to increase the support stability of the folding bracket 100 and reduce the impact of factors such as vibration, strong wind and collision with objects on the folding bracket 100.

[0054] This utility model also proposes a photovoltaic folding panel, which includes multiple photovoltaic panels 200 and a folding bracket 100. The specific structure of the folding bracket 100 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 photovoltaic panels 200 can be stacked together, and at least one folding bracket 100 is provided and installed on the back side of the photovoltaic panels 200.

[0055] 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.
