Description

Technical Field

[0001] This utility model relates to the field of building materials and decoration technology, specifically to a roller blind type solar panel device for windows. Background Technology

[0002] Currently, examples of utilizing solar energy include solar water heaters, solar air conditioners, and building-integrated photovoltaics (BIPV). BIPV is a new concept in solar power generation, which simply means installing solar photovoltaic arrays on the exterior surface of a building's envelope to provide electricity. Depending on how the photovoltaic array is integrated with the building, BIPV can be divided into two main categories: the first is the integration of the photovoltaic array with the building, where the array is attached to the building, and the building acts as a support for the array; the second is the integration of the photovoltaic array with the building, where the photovoltaic modules appear as a building material, and the photovoltaic array becomes an integral part of the building.

[0003] Existing applications of solar energy in buildings, besides integrating photovoltaic arrays with buildings, also include combining photovoltaic panels with windows. However, the existing combination of photovoltaic panels and windows has some shortcomings. For example, windows have different orientations and different hours of sunshine throughout the day. Directly applying photovoltaic panels to windows can affect the lighting effect when sunlight does not directly hit the windows. Utility Model Content

[0004] To address the technical deficiencies in the prior art, this utility model proposes a roller blind-type solar panel device for windows, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: A roller shutter type solar panel device for windows includes a housing, a frame, a drive assembly, and a photovoltaic module. The frame has a chamber for accommodating the drive assembly and the photovoltaic module. The drive assembly includes a drive motor and a drive shaft connected to the output end of the drive motor. The photovoltaic module includes a plurality of photovoltaic panels arranged around the drive shaft and a hinge structure connecting the ends of two adjacent photovoltaic panels. The photovoltaic panels are spiraled from the inside to the outside of the drive shaft with the drive shaft as the axis. A magnetic attraction assembly is provided between the inner side of the photovoltaic panel and the frame.

[0005] As an improvement to the above solution, the frame includes a first support column and a second support column arranged vertically, and a horizontal support column connecting the bottom of the first support column and the second support column. The top ends of the first support column and the second support column are fixed to the two ends of the outer shell, respectively. The first support column, the second support column and the transverse support column surround the lower part of the outer shell, thereby forming the frame.

[0006] As an improvement to the above solution, the bottom end of the outer shell has an opening extending along its length direction, the inner side of the first support column is provided with a guide groove one extending along its length direction, the inner side of the second support column is provided with a guide groove two extending along its length direction, and one end of the guide groove one and the guide groove two are aligned with the end of the opening.

[0007] As an improvement to the above solution, the drive motor is located at one end of the chamber, the output end of the drive motor is provided with a drive gear one, and one end of the drive shaft is provided with a drive gear two that is adapted to the drive gear one.

[0008] As an improvement to the above solution, the drive shaft is a polygonal cylinder, the outer surface of the drive shaft is provided with an arc-shaped groove to accommodate the hinge structure, and both ends of the drive shaft are provided with cylindrical connecting posts integrally formed with the drive shaft.

[0009] As an improvement to the above solution, the photovoltaic panel includes a photovoltaic surface and a fixing frame for fixing the photovoltaic surface. The hinge structure is a hinge, and the two ends of the hinge structure are respectively connected to the inner sides of the fixing frames of two adjacent photovoltaic panels.

[0010] As an improvement to the above solution, the hinge structure includes an extension block disposed at the end of the photovoltaic panel, a first connecting block and a second connecting block attached to both sides of the extension block, and a connecting shaft passing through the extension block. One end of the connecting shaft is fixed to the inner end face of the first connecting block, and the other end of the connecting shaft passes through the extension block and is fixedly connected to the second connecting block.

[0011] As an improvement to the above solution, the transverse support column has an upward-opening groove along its length, a first magnetic block is provided in the groove, and a second magnetic block is provided at the bottom of the outermost photovoltaic panel of the photovoltaic module.

[0012] The beneficial effects of this utility model are as follows: the driving component drives the driving shaft to rotate, thereby retracting the photovoltaic panel into the cavity or unfolding it along the guide groove one and guide groove two. The photovoltaic panel is retracted and unfolded by the driving component. When the sunlight is directly overhead, it unfolds to block the sunlight and achieves a shading effect. When the sunlight is not directly overhead, the photovoltaic panel can be retracted into the cavity without affecting the lighting effect of the window. When the photovoltaic panel is unfolded to the bottom, the photovoltaic panel and the frame are attracted and fixed by a magnetic component, reducing the collision between the photovoltaic panel and the frame when unfolded.

The axis of the connecting post 36 is aligned with the axis of the hexagonal prism. During winding, the photovoltaic panel 41 is wound layer by layer in a spiral shape on the outside of the drive shaft 32.

[0030] In a second embodiment of the hinge structure 5, the hinge structure 5 includes an extension block 51 disposed at the end of the photovoltaic panel 41, a first connecting block 52 and a second connecting block 53 attached to both sides of the extension block 51, and a connecting shaft 54 ​​passing through the extension block 51. One end of the connecting shaft 54 ​​is fixed to the inner end face of the first connecting block 52, and the other end of the connecting shaft 54 ​​passes through the extension block 51 and is fixedly connected to the second connecting block 53. Two connecting shafts 54 are provided between the first connecting block 52 and the second connecting block 53. By passing the two connecting shafts 54 through the extension blocks 51 at the ends of the two adjacent photovoltaic panels 41, the two adjacent photovoltaic panels 41 are hinged together, and the included angle between the two adjacent photovoltaic panels 41 can be adjusted when they are rolled up.
