Description

Technical Field

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

[0002] With the widespread use of photovoltaic (PV) power generation equipment in portable and small-scale applications, foldable and adjustable-angle PV brackets have become key components for improving light efficiency and operational flexibility. Existing foldable PV brackets mostly employ mechanical hinges or multi-segment locking structures, achieving angle adjustment through pins or positioning holes. These structures have the following problems:

[0003] On the one hand, fixed-angle positioning lacks continuity, preventing users from making precise adjustments based on the actual angle of sunlight, thus limiting optimal orientation control of photovoltaic modules. On the other hand, multi-segment positioning structures are prone to wear and tear or gaps during long-term use, leading to loosening or swaying of the support structure, affecting the stability and lifespan of the photovoltaic modules. Furthermore, some structures introduce springs, ratchet mechanisms, and other devices to achieve damping retention, which not only results in complex structures and high costs but also hinders portability and mass deployment. Utility Model Content

[0004] The main objective of this invention is to provide a photovoltaic folding panel bracket and a photovoltaic device to at least solve the technical problems mentioned in the related art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] In a first aspect, this utility model provides a photovoltaic folding panel bracket, which includes a fixing component, a fastener, a bracket, and a flexible locking component.

[0007] One side of the fastener is used to fix it to the photovoltaic module, and the other side of the fastener has a through hole;

[0008] The fastener passes through the through hole where the flexible locking member is embedded, and makes the fixing member rotatably connected to the bracket;

[0009] The flexible locking element is located between the inner wall of the through hole and the outer surface of the fastener, and is used to generate radial friction force.

[0010] A second aspect of this utility model also provides a photovoltaic device, including a photovoltaic module and a photovoltaic folding plate bracket as described in the first aspect, wherein the photovoltaic folding plate bracket is rotatable relative to the photovoltaic module.

[0028] Please refer to them in order. Figures 1 to 5 This application provides a photovoltaic folding panel bracket 1, which includes a fixing member 11, a fastener 12, a bracket 14, and a flexible locking member 13. The components are described below:

[0029] The fastener 11 serves as a fixing plate for fixing to an external photovoltaic module 2 (e.g., a photovoltaic panel). One side of the fastener 11 is used to connect and fix to the photovoltaic module 2, for example, by fixing it to the frame of the photovoltaic module by means of screws, rivets, etc. The other side of the fastener 11 is provided with a pair of oppositely arranged through holes 1121 for installing fasteners, locking fittings (nuts), etc.

[0030] The fastener 12 can be a bolt or other fastening structure, which passes through the through hole 1121 of the fixing member 11 and cooperates with the bracket 14 to realize the rotational connection between the fixing member 11 and the bracket 14. At the same time, a flexible locking member 13 is embedded in the through hole, preferably a sleeve-shaped member made of elastic material.

[0031] The flexible locking element 13 is disposed between the inner wall of the through hole and the outer surface of the fastener 12. When the fastener 12 is axially locked, the flexible locking element 13 is radially compressed, thereby generating a stable radial frictional force between its outer wall and the inner wall of the through hole 1121, and between the inner wall and the outer surface of the fastener. This frictional force provides an adjustable-angle damping retention function. This allows the bracket 14 to remain stably stationary at any angle within its maximum adjustment range, preventing loosening or swaying caused by external interference or gravity, thus improving the stability of the photovoltaic module.

[0032] It should be understood that the flexible locking element 13 can be a hollow locking element made of plastic, possessing good elastic recovery and controllable radial deformation capability, providing stable and adjustable frictional force during the locking process of the fastener 12. Furthermore, the flexible locking element 13 can also be made of rubber, thermoplastic elastomer, or polyurethane material, and its structure can be sleeve-type, corrugated, or multi-groove type. The specific shape and material selection can be flexibly adjusted according to the usage environment, friction requirements, and durability requirements. Any structure that possesses a certain degree of flexibility and can generate radial expansion to form frictional resistance under axial force can be considered an implementation of the flexible locking element 13 in this application and falls within the protection scope of this application.

[0033] As can be seen, the photovoltaic folding panel bracket of this application embodiment forms an axial locking structure by setting a flexible locking member in the through hole of the fixing member and having the fastener pass between the flexible locking member and the through hole. When locking, the flexible locking member generates radial friction force, thereby forming a stable damping connection between the fixing member and the bracket. This not only enables the bracket to maintain any angle position within the maximum adjustment range, but also effectively avoids angle deviation or rapid swing caused by loosening. At the same time, the structure is simple and easy to assemble, improving the stability and reliability of the bracket.

[0034] In an optional embodiment of this application, the photovoltaic folding panel bracket 1 further includes a locking fitting 15.

[0035] Specifically, the locking fitting 15 is disposed in the through hole 1121 and is adapted to the fastener 12, mainly used to form a reliable axial locking connection between the fixing member 11 and the bracket 14.

[0036] For example, when the locking fitting 15 is a nut, its internal thread engages with the external thread of the fastener 12 (such as a bolt). That is, during installation, the threaded end of the fastener 12 passes through the flexible locking member 13 in the through hole and connects with the locking fitting 15. Rotating the fastener 12 can tighten it with the locking fitting 15 (the distance between them gets closer as the number of rotations increases). Correspondingly, axial force is applied to radially compress the flexible locking member 13 (causing a certain deformation). Finally, the flexible locking member 13 forms a more stable radial friction force between the inner wall of the through hole and the outer surface of the fastener 12.

[0037] It should be noted that the more turns the fastener 12 makes or the tighter it is tightened (indicating that the fastener 12 is closer to the location of the flexible locking member 13), the greater the axial force applied to the flexible locking member 13 by the fastener 12 in conjunction with the locking fitting 15 (nut). This results in a stronger radial clamping effect of the flexible locking member 13 and a greater radial friction force, which further improves the stability of the subsequent support for the rotation angle of the photovoltaic module.

[0038] Please Figures 1 to 5On this basis, further combine Figure 6 For reference, the photovoltaic folding panel bracket 1 also includes a connector 16.

[0039] Specifically, the connector 16 is used to connect the fixing member 11 and the bracket 14. One end of the connector 16 has a bracket hole 163 for cooperating with the bracket 14, and the other end has a connection hole 161, which is opposite to the through hole 1121 on the fixing member 11 and is used to cooperate with the fastener 12.

[0040] During assembly, the fastener 12 passes sequentially through the through hole of the fixing member 11, the flexible locking member 13, and the connecting hole 161 of the connector 16, and forms an axial clamping fit with the locking fitting (such as the limiting locking member 15) provided on the other side of the through hole. Through the locking action of the fastener 12, the flexible locking member 13 is compressed inside the through hole and undergoes radial expansion, thereby forming a stable frictional force between the outer surface of the fastener and the inner wall of the through hole, realizing the damped rotational connection between the fixing member 11 and the connector 16.

[0041] In an optional embodiment of this application, the photovoltaic folding plate bracket 1 further includes a cylindrical pin 17.

[0042] Specifically, the end of the connector 16 that connects to the bracket 14 is provided with a pin hole 162, and a cylindrical pin 17 is inserted into and fixed in the pin hole 162, thereby achieving a reliable connection between the connector 16 and the bracket 14. This structure not only simplifies the connection method and facilitates assembly and disassembly, but also allows for a certain degree of rotation while maintaining connection stability, further improving the flexibility and structural strength of the bracket during angle adjustment.

[0043] During installation, the cylindrical pin 17 can be installed in the pin hole 162 by interference fit, positioning glue or elastic buckle. A limiting structure can also be set to prevent axial displacement, so as to ensure the stability and anti-loosening ability of the connector 16 during long-term use.

[0044] It should also be noted that in the embodiments of this application, the photovoltaic folding panel bracket 1 may also include pin structures of other shapes, that is, it is not limited to cylindrical structures, and other conformal pins may be selected according to specific application requirements, such as square pins, conical pins or irregular pins with limiting shoulders, to adapt to pin holes 162 of different shapes and realize the positioning and connection functions between the connector 16 and the bracket 14.

[0045] Please see Figure 7 The stent includes a first stent body 141, a second stent body 142 and a third stent body 143.

[0046] Specifically, the first support body 141, the second support body 142, and the third support body 143 together form a U-shaped or gate-shaped structure to provide stable and adjustable support for the photovoltaic module 2. The first support body 141 and one end of the second support body 142 are vertically fixed, and the third support body 143 and the other end of the second support body 142 are vertically fixed, thus forming a parallel support structure with the first support body 141 at one end and the third support body 143 at the other end. The second support body 142 serves as its connecting crossbar.

[0047] In this embodiment, the first support body 141 and the third support body 143 are arranged in parallel in space to maintain the symmetry and force balance of the support; their free ends are respectively rotatably connected to two fixing parts 11 through corresponding connectors 16, thereby realizing the stable support and adjustment of the photovoltaic module 2 at multiple angles.

[0048] Additionally, please Figure 7 Further reference Figures 8 to 9 The rotation angle between the bracket 14 and the fixing member 11 is limited by the structural form, relative positional relationship, and connection method of the connector 16 and the fixing member 11. Specifically, the end shape of the connector 16, the position of the connecting hole, the distance between the first connecting part 112 and the second connecting part 113 in the fixing member 11, and the surrounding method will all affect the maximum rotation range of the bracket 14 relative to the fixing member 11. If the end of the connector is elongated or has a limiting edge, its angle of movement may be limited due to collision with the edge of the fixing member; at the same time, if the connecting part of the fixing member is designed as a semi-enclosed structure, its rotation stroke may also be limited.

[0049] In an optional embodiment of this application, a shock-absorbing component 144 may also be fitted onto the second support body 142.

[0050] Specifically, the shock-absorbing component 144 is used to buffer and absorb the impact force or vibration experienced by the support structure during the folding or unfolding of the photovoltaic module, thereby preventing structural damage or angular displacement. The shock-absorbing component 144 is preferably a sleeve-shaped member made of an elastic material, such as a rubber ring, foam sleeve, or silicone sleeve, tightly covering the outer periphery of the second support body 142. It provides limiting protection during folding, preventing direct contact and scratches between support bodies, while also enhancing the overall structural flexibility and safety of the support structure. Depending on actual usage requirements, the shock-absorbing component 144 can also be configured as a detachable or replaceable structure to improve maintenance convenience.

[0051] In an optional embodiment of this application, there are two connectors 16, two fasteners 11, two fasteners 12, multiple flexible locking members 13, and two locking mating members 15.

[0052] Specifically, one side of a fastener 11 is used to fix it to one side of a photovoltaic module 2, and the other side forms a through hole; a fastener 12 passes through the through hole where at least one flexible locking member 13 is embedded, the connecting hole 161 of a connector 16, and is threadedly connected to a locking fitting 15, so that the fastener 11 and the first support body 141 are rotatably connected through the connector 16; wherein, at least one flexible locking member 13 is disposed between the inner wall of the through hole and the outer surface of the fastener 12, and is compressed during the tightening of the fastener 12 to generate radial friction force, which is used to provide a damping and retaining function for the rotation angle.

[0053] Similarly, one side of another fastener 11 is used to fix it to the other side of the photovoltaic module 2, and the other side also has a through hole; another fastener 12 passes through the through hole where at least one flexible locking member 13 is embedded, the connecting hole 161 of another connector 16, and is threadedly connected to another locking fitting 15, so that the fastener 11 and the third support body 143 are rotatably connected through another connector 16; wherein the flexible locking member 13 disposed in the through hole is also located between the inner wall and the outer surface of the fastener, and is also used to generate radial friction force to achieve stable retention of the structure in multiple angular positions.

[0054] This embodiment, through a connection structure arranged symmetrically on both sides, not only improves the overall adjustment flexibility of the photovoltaic module, but also enhances the mechanical balance and installation adaptability of the support system.

[0055] Please return and refer to Figure 5 On the other side of the fastener 11, a first connecting portion 112 and a second connecting portion 113 are formed symmetrically.

[0056] Specifically, the first connecting part 112 and the second connecting part 113 are respectively provided with through holes 1121, and the two through holes 1121 are aligned with each other for installing fasteners 12. The other end of the connector 16 is located between the first connecting part 112 and the second connecting part 113. The fastener 12 passes through the two through holes 1121 and the connecting hole 161 on the connector 16, and cooperates with the locking fitting 15 in the through hole 1121, thereby realizing the rotatable connection between the fixing member 11 and the connector 16, that is, realizing the rotation between the fixing member 11 and the bracket 14.

[0057] In addition, a photovoltaic mounting hole 111 is formed on one side of the fastener 11.

[0058] The photovoltaic mounting hole 111 is a through hole structure, suitable for installing bolts, screws or other standard fasteners. During installation, screws can be inserted through the corresponding holes on the photovoltaic module frame and screwed into the photovoltaic mounting hole 111 of the fastener 11, thereby achieving a firm connection between the fastener 11 and the photovoltaic module 2, ensuring that the module does not shift or fall off during angle adjustment.

[0059] This application also provides a photovoltaic device, including a photovoltaic module 2 (e.g., a photovoltaic module with an aluminum alloy outer frame) and a photovoltaic folding plate bracket 1 as described in the above embodiments, wherein the photovoltaic folding plate bracket 1 is rotatable relative to the photovoltaic module 2.

[0060] The photovoltaic folding panel bracket and photovoltaic device of this application embodiment form an axial locking structure by setting a flexible locking member in the through hole of the fixing member and having a fastener pass between the flexible locking member and the through hole. When locking, the flexible locking member generates radial friction force, thereby forming a stable damping connection between the fixing member and the bracket. This not only enables the bracket to maintain any angle position within the maximum adjustment range, but also effectively avoids angle deviation or rapid swing caused by loosening. At the same time, the structure is simple and easy to assemble, improving the stability and reliability of the bracket, and has good practical value and promotion prospects.

For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model.
