Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and more particularly to a foldable solar panel. Background Technology

[0002] To facilitate the storage and transportation of solar panels, hinge structures are usually installed between the working units of the solar panels. Because the hinge structure is relatively smooth, the solar panels may pinch the workers' hands too quickly when folded due to their own weight, causing injury. Summary of the Invention

[0003] The purpose of this application is to provide a foldable solar panel that makes the folding process safer and smoother.

[0004] To achieve the above objectives, this application provides a foldable solar panel: including a connecting frame, the connecting frame including an inner plate, the inner plate having hinge plates at both ends, a pair of photovoltaic units connected between the two hinge plates, the photovoltaic unit having a tangent tube on one side, the two ends of the tangent tube having coaxial hinge shafts adapted to be rotatably connected with the hinge plates, the photovoltaic unit also having a baffle plate on the same side of the tangent tube, the baffle plate forming an embedded groove with the tangent tube, adapted to fit with the inner plate, improving the fit between the photovoltaic unit and the connecting frame.

[0005] As a preferred embodiment, the connecting frame is integrally molded from plastic, with the two hinge plates extending in the same direction and perpendicular to the inner panel, facilitating integration with the photovoltaic unit.

[0006] As a preferred embodiment, each of the hinge plates has two through holes, and the two through holes on the two hinge plates are aligned with each other. The hinge shafts at both ends of the same tangent cylinder are engaged with the two through holes to form a rotating pair, thereby restricting the relative degrees of freedom of the photovoltaic unit.

[0007] As a preferred embodiment, the outer surfaces of the two tangential cylinders are always in contact when the photovoltaic unit rotates relative to the connecting frame, which can better maintain the rotational synchronization of the two photovoltaic units.

[0008] As a preferred embodiment, the two corners of the hinge plate away from the inner panel are rounded to reduce motion interference with the moving parts.

[0009] As a preferred embodiment, the photovoltaic unit includes a rectangular photovoltaic core, the outer side of which is wrapped with a protective frame to reduce impact damage to the edges of the photovoltaic core.

[0010] As a preferred embodiment, the baffle plate and the tangential cylinder are located on the same side of the protective frame, forming an integral structure, both made of aluminum alloy material, which balances lightweight and high strength.

[0011] As a preferred embodiment, the tangential tube is hollow inside, which is suitable for cables that are electrically connected to the photovoltaic panel core to pass through, providing good shielding and protection for the cables and the connection ends between the cables and the photovoltaic panel core.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a baffle plate structure that protrudes from the outer side of the protective frame, it can generate relative motion friction with the embedded plate during the folding process of the photovoltaic panel, thereby preventing the two photovoltaic units from getting too close to each other too quickly. This makes the solar panel more stable when folding, effectively reducing the risk of operators being pinched.

[0014] (2) Since the two baffles can abut against each other and constrain the inner panel, the solar panel can have good flatness and maintain stability after unfolding. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figure 1-10 The foldable solar panel shown includes a one-piece injection-molded plastic connecting frame 1 with sufficient strength to prevent deformation and a certain degree of elasticity to recover when bending deformation occurs. The connecting frame 1 includes a flat inner plate 101 with hinge plates 102 extending in the opposite direction at both ends of the inner plate 101. The two hinge plates 102 extend in the same direction, are parallel to each other, and are perpendicular to the inner plate 101. The two corners of the hinge plates 102 away from the inner plate 101 are rounded to reduce interference with relative movement.

[0031] A pair of photovoltaic units 2 are connected between two hinge plates 102. The photovoltaic units 2 are folded relative to each other to form the most basic foldable structure. Of course, one photovoltaic unit 2 can be connected to two connecting frames 1 and folded relative to another photovoltaic unit 2 in another opposite direction. One side of the photovoltaic unit 2 has a tangent tube 203. The cross-section of the tangent tube 203 has a distinct semi-circular shape. Both ends of the tangent tube 203 have coaxial hinge shafts 204 for rotatably connecting with the hinge plates 102. In fact, each hinge plate 102 has two identical openings. The through holes 103 on the two hinge plates 102 are aligned with each other. The hinge shafts 204 at both ends of the same tangent cylinder 203 are inserted into the two through holes 103 to form a rotating pair, thereby restricting the relative position of the photovoltaic unit 2 and the connecting frame 1. The outer surfaces of the two tangent cylinders 203 are always in contact when the photovoltaic unit 2 rotates relative to the connecting frame 1, that is, they are kept in a tangent state. By utilizing the frictional force of mutual contact, when the two photovoltaic units 2 are in contact with each other, the plane of the inner plate 101 is perpendicular to the plane of the photovoltaic unit 2.

[0032] The photovoltaic unit 2 also has a baffle plate 202 on the same side as the tangent tube 203. The baffle plate 202 is flush with one of the larger end faces of the photovoltaic unit 2. An embedded slot 206 is formed between the baffle plate 202 and the tangent tube 203, which can fit with the embedded plate 101 when the photovoltaic unit 2 is fully unfolded. The photovoltaic unit 2 includes a rectangular photovoltaic core 205. The outer side of the photovoltaic core 205 is wrapped with a protective frame 201 of uniform thickness. The baffle plate 202 and the tangent tube 203 are located on the same side of the protective frame 201 and are an integral structure. Both are made of aluminum alloy. The tangent tube 203 is hollow inside and is used for the cables that are electrically connected to the photovoltaic core 205 to pass through, which effectively shields and protects the cable structure.

[0033] Working principle: When unfolding is required, the edges of the two photovoltaic units 2, which were originally attached to each other, are pinched together to force them to move away from each other. The inner panel 101 presses against the baffle plate 202. Due to the pressure, the side of the inner panel 101 undergoes elastic deformation, and the baffle plate 202 slides against the edge of the inner panel 101. Due to the resistance of contact friction, it is difficult to maintain relative movement by the weight of the photovoltaic units 2 alone. A certain amount of force needs to be applied by the operator until the inner panel 101 slides completely into the inner slot 206, making close contact with the baffle plate 202 and parallel to it. At this time, the two photovoltaic cores 205 are in the same horizontal plane. The edges of the baffle plates 202 abut against each other, and together with the supporting effect of the inner plate 101 on the tangent cylinder 203, the two photovoltaic units 2 have good flat stability. When folding is required, the edges of the two photovoltaic units 2 that were originally flat are pinched by both hands, forcing them to move closer to each other. The baffle plates 202 deviate from the direction parallel to the inner plate 101, forcing the edge of the inner plate 101 to warp and make close contact with the inner side of the baffle plates 202 again to generate sliding friction. Due to the resistance, it is not easy to pinch fingers when the photovoltaic units 2 move closer to each other too quickly during folding, effectively reducing the risk of injury to workers during the folding process.
