Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically a photovoltaic panel folding support structure. Background Technology

[0002] Currently, portable photovoltaic (PV) power generation devices are widely used in field operations, emergency power supply, and outdoor camping. They primarily rely on a foldable support structure to unfold the PV panels for receiving solar energy during use and fold them up to reduce space occupation during storage. Existing PV panel support structures typically use hinged connections or single-axis rotational supports to connect multiple PV panels sequentially to form a foldable unit. While this type of structure can form a PV panel of a certain area when unfolded, its support stability is poor. Especially when there is a lack of synchronous locking mechanisms in the lateral and longitudinal directions, the PV panels are prone to deformation or wobbling, affecting the effective reception of solar energy.

[0003] In addition, some existing foldable photovoltaic panel structures achieve storage through folding movement in only one direction during the folding process. The lack of coordination between the frame component and the edge strip component results in a still large volume after folding, which is not conducive to carrying and storage. In the unfolded state, due to the limited number and unreasonable distribution of support points, the adjacent edges of the photovoltaic panel cannot be adequately supported, and the overall plane is prone to sinking or warping, affecting the reliability of long-term use.

[0004] Furthermore, existing portable photovoltaic panels often neglect ease of operation during folding and unfolding. The handheld operating position is poorly designed or lacks a rotating mechanism, requiring significant force for users to switch modes, which is inconvenient for frequent use. Simultaneously, structural locking relies heavily on simple snap-fit ​​or bolt connections, resulting in insufficient locking force or cumbersome assembly and disassembly, leading to a poor user experience. In summary, existing foldable photovoltaic panel supports still have significant shortcomings in structural stability, compact folding and storage, and ease of operation. There is an urgent need for an improved foldable photovoltaic panel support structure that provides coordinated movement during folding and unfolding, stable support, and is easy to carry and lock. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: a photovoltaic panel folding support structure, including a first frame, a second frame, a photovoltaic panel, connecting lugs, edge strip groups, and a support frame group. The first frame and the second frame are respectively set at both ends of the photovoltaic panel, and the surface is provided with a handle structure for easy operation. The photovoltaic panel is formed by multiple panels connected in sequence by hinges, and can be switched between a folded state and an unfolded state. The edge strip groups are symmetrically arranged at the four corners of the connecting lugs and are used for rotatable connection with the first frame, the second frame, and the connecting lugs. The support frame group is horizontally connected between the connecting lugs, which can support and connect the adjacent edges of the photovoltaic panel, and rotatably connect with both sides of the connecting lugs, thereby realizing the conversion of the photovoltaic panel between the two states.

[0007] In a preferred embodiment, the first and second frames are respectively arranged at both ends of the photovoltaic panel and have handle structures on their outer surfaces, allowing for hand-pulling operations during folding or unfolding of the photovoltaic panel, and serving as handles when stored. The photovoltaic panel is composed of several panels sequentially hinged between the first and second frames, which cooperate to form a continuous photovoltaic power generation plane when unfolded, and overlap to reduce space occupation when folded, thus achieving a portable design. This structure enables efficient unfolding and stable operation of the photovoltaic panel within a limited space.

[0008] In a preferred embodiment, the edge strips are symmetrically arranged at the four corners of the lugs. Both ends of the edge strips are connected to the first frame, the second frame, and the lug surface via revolute joints. During folding or unfolding, the edge strips can rotate in a direction perpendicular to the first and second frames, thus forming effective longitudinal support when unfolded and retracting inwards when folded, achieving a compact structure. This design ensures the longitudinal stability of the photovoltaic panel.

[0009] In a preferred embodiment, the support frame assembly is laterally positioned between the connecting lugs, with both ends of the support frame assembly rotatably connected to the sides of the connecting lugs. This supports and connects the adjacent edges of the photovoltaic panel, ensuring that the edges of the photovoltaic panel are straight and not easily warped in the unfolded state. In the folded state, it rotates and retracts along the line connecting the first and second frame sides, achieving a compact lateral structure. This design provides stable support in the lateral direction while also ensuring convenient folding and storage.

[0010] In a preferred example, both the first and second frame surfaces are provided with lugs, and the lug surface is provided with a snap groove that mates with the lug. After the lug is inserted into the snap groove, the first and second frame surfaces and the lug surface can be fastened and locked, thereby improving the overall structural stability of the bracket in the folded state and preventing it from loosening and automatically unfolding in the folded storage state.

[0011] In a preferred embodiment, the surface of the connecting lug is provided with a truss, which can support the middle part of the photovoltaic panel when the photovoltaic panel is unfolded, so that the bottom surface of the photovoltaic panel is in contact with the top surface of the truss and the support frame assembly at the same time, thereby effectively dispersing the force, enhancing the support strength of the middle part, and preventing the photovoltaic panel from deforming due to the sinking of the middle part.

[0012] In a preferred example, the edge strip assembly includes two connecting rods that are rotatably connected to each other. Each connecting rod is fixed to the two sides of the photovoltaic panel. The folding and unfolding of the photovoltaic panel is achieved by the rotation between the connecting rods, and a lateral limiting function is provided in the unfolded state to ensure the relative position stability between the photovoltaic panels.

[0013] In a preferred example, the support frame assembly includes two horizontally arranged and rotatably connected support frame rods. The end of each support frame rod is rotatably connected to the first frame, the second frame, and the lug surface via a pivot. It can rotate flexibly during folding and unfolding to adapt to changes in the state of the photovoltaic panel and ensure stable edge support.

[0014] In a preferred example, the handle structure is rotatably connected to the outer sides of the first and second frames, facilitating hand-held pulling during folding and unfolding, and also serving as a handle when the photovoltaic panel is folded and stored, thereby improving the portability of the device.

[0015] Specifically, through the above structural design, this utility model realizes the rapid switching between the folded and unfolded states of the photovoltaic panel. In the folded state, it can be folded in both the longitudinal and transverse directions to form a compact and portable whole. In the unfolded state, it has stable support in both the longitudinal and transverse directions, and the photovoltaic panel forms a flat and continuous light-receiving surface, which not only improves the efficiency of light energy utilization, but also ensures the structural stability for long-term use.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] 1. In this utility model, through the coordinated operation of the first frame, the second frame, the photovoltaic panel, the connecting lugs, the side strip assembly, and the support frame assembly, the photovoltaic panel can quickly switch between a folded state and an unfolded state. In the folded state, the support frame assembly rotates and retracts along the line connecting the first and second frames, while the side strip assembly retracts vertically, resulting in a compact overall structure that occupies little space and is easy to carry and store. In the unfolded state, the support frame assembly and the side strip assembly unfold and support the photovoltaic panel in their respective directions, forming a continuous plane and maintaining structural stability, thereby improving the light energy utilization efficiency and operational reliability.

[0018] 2. In this utility model, the interlocking structure of the insert and the latch can effectively lock the positional relationship between the first frame, the second frame and the connecting ear in the folded state, thereby enhancing the overall stability. At the same time, a truss is added to the surface of the connecting ear, so that the middle part of the photovoltaic panel is given additional support in the unfolded state, avoiding deformation or damage caused by uneven force and extending the service life.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of a photovoltaic panel folding support structure provided by this utility model.

[0028] Combination Figures 1-4 As shown, the photovoltaic panel folding support structure provided by this utility model includes a first frame 1, a second frame 2, a photovoltaic panel 3, a connecting lug 4, a side strip group 5, and a support frame group 6.

[0029] The first frame 1 and the second frame 2 are respectively arranged at both ends of the photovoltaic panel 3, and a handle structure is provided on its outer surface for easy hand holding, so that the operator can pull the photovoltaic panel during folding or unfolding, and use it as a handle for carrying when stored.

[0030] The photovoltaic panel 3 comprises several pieces, which are sequentially hinged between the first frame 1 and the second frame 2 to form a foldable structure. In the folded state, the photovoltaic panels 3 are stacked together to reduce space occupation. In the unfolded state, the photovoltaic panels 3 unfold along the hinge direction and combine to form a continuous plane for receiving light energy.

[0031] The edge strip groups 5 are symmetrically arranged at the four corners of the lugs 4. Each edge strip group 5 is connected at both ends to the first frame 1, the second frame 2, and the surface of the lugs 4 via a rotating joint. Through the rotational engagement of the edge strip groups 5, the photovoltaic panel 3 can be supported and guided between the folded and unfolded states.

[0032] The support frame assembly 6 is horizontally positioned between the lugs 4 to support and connect adjacent edges of the photovoltaic panels 3. The two ends of the support frame assembly 6 are rotatably connected to the opposite sides of the lugs 4. During folding, it retracts horizontally; during unfolding, it unfolds horizontally, providing stable support to the adjacent edges of each photovoltaic panel 3.

[0033] In a preferred embodiment, the surfaces of the first frame 1 and the second frame 2 are provided with lugs 11, and the surface of the connecting lug 4 is provided with a snap groove 42 that cooperates with the lugs 11. The lugs 11 can be inserted into the snap groove 42 to realize the snap locking between the first frame 1, the second frame 2 and the connecting lug 4, thereby ensuring the stability of the structure in the folded state.

[0034] In another embodiment, the surface of the connecting lug 4 is provided with a truss 41, which is used to form an additional support in the middle of the photovoltaic panel 3, so that the bottom surface of the photovoltaic panel 3 is in contact with the top surface of the truss 41 and the support frame assembly 6 in the unfolded state, thereby improving the overall load-bearing stability of the photovoltaic panel 3.

[0035] The edge strip group 5 may include two connecting rods that are rotatably connected to each other. Each connecting rod is fixed to the two sides of the photovoltaic panel 3. The folding and unfolding actions of the photovoltaic panel 3 are realized by the rotation between the connecting rods, and the lateral position of the photovoltaic panel 3 is limited in the unfolded state.

[0036] The support frame assembly 6 may include two horizontally arranged and rotatably connected support frame rods. The end of each support frame rod is rotatably connected to the surface of the first frame 1, the second frame 2 and the connecting lug 4 through a pivot, so that the support frame assembly 6 can rotate flexibly during folding and unfolding, ensuring that the edge of the photovoltaic panel 3 is effectively supported in different states.

[0037] The handle structure is rotatably connected to the outer side of the first frame 1 and the second frame 2. When the photovoltaic panel 3 is in a folded state, the handle structure can be used as a handle for carrying. When the photovoltaic panel 3 is in the process of unfolding or folding, the handle structure is used for hand-held pulling operation, which makes it convenient for the operator to complete the state change.

[0038] In the folded state, the frame assembly 6 rotates relative to the first frame 1 and the second frame 2 along the line connecting them to the folded position, and the side strip assembly 5 rotates relative to the folded position along the longitudinal direction perpendicular to the surfaces of the first frame 1 and the second frame 2, so that the photovoltaic panel 3 can be compactly stored in both the longitudinal and transverse directions. In the unfolded state, the frame assembly 6 and the side strip assembly 5 unfold and lock in their respective directions, so that the photovoltaic panel 3 forms a continuous plane and maintains structural stability.

[0039] Through the above structural design, this utility model can realize the rapid switching between folded and unfolded states of photovoltaic panels. When folded, the structure is compact and easy to carry and store, while when unfolded, the structure is stable and ensures the efficiency of light energy utilization. It is suitable for portable photovoltaic power generation devices and other occasions.
