Description

Technical Field

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

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials, such as silicon. PV panels can be made in various shapes, and they can be connected to generate more electricity. PV panels are used on rooftops and building surfaces, and are even used as part of windows, skylights, or shading devices. These PV installations are often referred to as building-integrated photovoltaic (BIPV) systems.

[0003] Currently, existing foldable photovoltaic panels are mostly operated by setting a pivot between two photovoltaic panels. The panels are rotated by manually pulling them, thereby controlling the folding and unfolding of the photovoltaic panels. This is not only cumbersome and inconvenient to operate, but also requires additional fixing of the two photovoltaic panels after rotation. Furthermore, it is difficult to accurately control the folding angle between the two photovoltaic panels, which fails to meet actual needs and results in poor performance. Utility Model Content

[0004] The purpose of this invention is to provide a foldable photovoltaic panel that allows two photovoltaic panels to be rotated within a U-shaped fixing frame to fold and merge, and vice versa, to unfold. It also allows for precise control of the folding angle between the two photovoltaic panels to better meet usage requirements.

[0005] A foldable photovoltaic panel is folded by a bolt structure. The bolt structure includes a support plate and a bearing seat. The bearing seat is vertically arranged at both ends of the support plate and has two bearings. Two connecting shafts are connected to the sides of the two photovoltaic panels to be joined and pass through the corresponding bearings to join the two photovoltaic panels.

[0006] A support frame is mounted on one end of a support plate, and a protective frame is installed on the outside of the support frame. A cover plate is detachably connected to the open end of the protective frame. Both ends of the support frame are rotatably connected to drive gears via rotating shafts, and the two drive gears mesh with each other. The ends of the two connecting shafts are respectively connected to the two drive gears. One end of the protective frame is rotatably connected to a transmission gear via a rotating shaft, and the other end of the protective frame is provided with a movable column. One of the drive gears is connected to the output shaft of the transmission gear, and a toothed plate that meshes with the transmission gear is provided on one side of the movable column.

[0007] Preferably, one end of the protective frame is rotatably connected to a threaded rod via a bearing, and a drive motor is fixed to the top of the protective frame. The output end of the drive motor extends into the protective frame and is connected to the threaded rod.

[0008] Preferably, the drive motor is provided with a protective cover.

[0009] Preferably, the movable column is provided with a limit strip on one side relative to the toothed plate, and a limit groove matching the limit strip is provided on one side of the inner side of the protective frame.

[0010] Preferably, the top of the support frame is provided with multiple hollow cavities.

[0011] Preferably, bolts are provided at all four ends of the side wall of the cover plate, and the cover plate is fixedly connected to the protective frame by bolts.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By setting up a fixed frame, support frame, protective frame, drive gear, transmission gear, and movable column, the movable column can drive the toothed plate to rotate the transmission gear. This allows the transmission gear to drive the two drive gears and connecting shafts to rotate inward or outward simultaneously. When the two connecting shafts rotate outward simultaneously, the two photovoltaic panels can rotate within the U-shaped fixed frame to fold and merge. Conversely, they can be unfolded. At the same time, the folding angle between the two photovoltaic panels can be precisely controlled to better meet usage requirements. The operation is simple and convenient, the structure is stable and reliable, and the performance is good. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] A foldable photovoltaic panel is disclosed, which achieves folding through a latch structure. The latch structure includes a support plate 1 and a bearing seat 16. The bearing seat 16 is vertically disposed at both ends of the support plate 1, and two bearings are disposed on the bearing seat 16. Two connecting shafts 3 are respectively connected to the sides of the two photovoltaic panels 2 to be spliced, and then pass through the corresponding bearings to achieve splicing of the two photovoltaic panels 2.

[0026] The connection between the connecting shaft 3 and the side of the photovoltaic panel 2 is a fixed connection, or a meshing gear is provided between the connecting shaft 3 and the side of the photovoltaic panel 2 for connection.

[0027] A support frame 4 is located at one end of a support plate 1, and a protective frame 6 is installed on the outside of the support frame 4. A cover plate 7 is detachably connected to the open end of the protective frame 6. Both ends of the support frame 4 are rotatably connected to drive gears 5 via rotating shafts, and the two drive gears 5 mesh with each other. The ends of the two connecting shafts 3 are respectively connected to the two drive gears 5. One end of the protective frame 6 is rotatably connected to a transmission gear 8 via a rotating shaft, and the other end of the protective frame 6 is provided with a movable column 9. One of the drive gears 5 is connected to the output shaft of the transmission gear 8, and a toothed plate 10 that meshes with the transmission gear 8 is provided on one side of the movable column 9.

[0028] The top of the support frame 4 has multiple hollow cavities. These hollow cavities can greatly reduce the weight of the component.

[0029] Bolts are provided at all four ends of the side wall of the cover plate 7, and the cover plate 7 is fixedly connected to the protective frame 6 by bolts. The bolt connection facilitates the fixing and separation of the protective frame 6 and the cover plate 7 for inspection and maintenance.

[0030] One end of the protective frame 6 is rotatably connected to a threaded rod 11 via a bearing, and a drive motor 12 is fixed to the top of the protective frame 6. The output end of the drive motor 12 extends into the protective frame 6 and is connected to the threaded rod 11.

[0031] In use, the threaded rod 11 can be driven to rotate by the drive motor 12, and then the threaded rod 11 can drive the movable column 9 to rise and fall in a straight line, so that the movable column 9 drives the toothed plate 10 to move. Then the toothed plate 10 drives the meshing transmission gear 8 to rotate, which can drive the connected drive gear 5 to rotate. Under the mutual meshing of the two drive gears 5, the drive gear 5 can drive the two connected connecting shafts 3 to rotate inward or outward at the same time. When the two connecting shafts 3 rotate outward at the same time, the two photovoltaic panels 2 can be driven to rotate in the U-shaped fixing frame 1 to fold and merge. Conversely, they can be unfolded. It can also precisely control the folding angle between the two photovoltaic panels 2 to better meet the usage requirements. The operation is simple and convenient, the structure is stable and reliable, and the use effect is good.

[0032] The drive motor 12 is a reversible motor or a bidirectional motor, and it is equipped with a protective cover 13. Based on this, the drive motor 12 can be protected by the protective cover 13.

[0033] A limit strip 14 is provided on one side of the movable column 9 relative to the toothed plate 10, and a limit groove 15 matching the limit strip 14 is provided on one side of the inner side of the protective frame 6. Based on this, by setting the limit strip 14 and the limit groove 15, the movable column 9 can drive the limit strip 14 to move within the limit groove 15, thereby supporting and limiting the movable column 9, so that the movable column 9 can rise and fall stably in a straight line.
