DETAILED DESCRIPTION

[0038] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] like Figures 1-8 As shown, the special-shaped component of the present invention includes:

[0040] Photovoltaic cell 100, the cross section of photovoltaic cell 100 along its thickness direction is triangular;

[0041] The frame profile 200 has a U-shaped cross section. The inner wall of the U-shaped opening of the frame profile 200 is sealed with the side, light-receiving surface, and backlight surface of the photovoltaic cell 100. Three frame profiles 200 are provided and connected end to end in sequence.

[0042] The fastening assembly is provided with three fastening assemblies and is respectively adjacent to the triangle of the photovoltaic cell 100. The fastening assembly includes a positioning rod 300 that passes through the photovoltaic cell 100 and extends along the thickness direction of the photovoltaic cell 100. Two fasteners are provided at both ends of the positioning rod 300. The frame profile 200 is clamped between the two fasteners, and at least one of the fasteners is detachably connected to the positioning rod 300.

[0043] In the special-shaped component of the present invention, the cross-section of the photovoltaic cell 100 along its own thickness direction is specifically an equilateral triangle (of course, it can also be other triangles, including but not limited to isosceles triangles and right triangles that are not equilateral triangles). It is preferred to adopt an equilateral triangle so that the three side arms of the circumferential outer edge of the photovoltaic cell 100 have the same length, so that the three frame profiles 200 connected to the photovoltaic cell 100 have the same length, which is convenient for assembly and connection.

[0044] The frame profile 200 includes two horizontal arms 201 and a vertical arm 202 integrally connected between the two horizontal arms 201. The vertical arm 202 and the two horizontal arms 201 extend evenly and parallel to the length direction of the frame profile 200. After the vertical arm 202 is connected to the two horizontal arms 201, the frame profile 200 has a U-shaped opening. When the frame profile 200 is connected to the photovoltaic cell 100, the vertical arm 202 is sealed and fitted with one of the side walls of the circumferential outer edge of the photovoltaic cell 100, and the two horizontal arms 201 are sealed and fitted with the light-receiving surface (i.e., the front side, used to receive sunlight) and the backlight surface (i.e., the back side, the side facing away from sunlight) of the photovoltaic cell 100, respectively.

[0045] There are three fastening components in total, which are respectively arranged in adjacent positions of the triangular position of the photovoltaic cell 100. Specifically, the fastening components include a positioning rod 300, which extends along the thickness direction of the photovoltaic cell 100 and penetrates the photovoltaic cell 100. Fasteners are installed at both ends of the positioning rod 300, and one of the fasteners is detachably connected to the end of the positioning rod 300, which is convenient for clamping the frame profile 200, thereby completing the fixation of the special-shaped component.

[0046] Compared with the prior art, in the present invention, the cross-section of the frame profile 200 is a U-shaped structure, and there is no need to set a cavity or assembly cavity on the frame profile 200 so that the corner code can be inserted to connect with the adjacent frame profile 200, thereby greatly reducing the production material consumption of the frame profile 200, reducing the production cost of the frame profile 200 and the special-shaped components, and reducing the weight of the frame profile 200, making it convenient to install and carry, which is beneficial to improving assembly efficiency. By passing the positioning rod 300 through the thickness direction of the photovoltaic cell 100, installing fasteners at both ends of the positioning rod 300, and using two fasteners to clamp the frame profile 200, the connection tightness between the three frame profiles 200 is guaranteed, thereby strengthening the structural strength of the special-shaped component.

[0047] In a preferred embodiment, the two fasteners are a protruding plate 400 integrally connected to the positioning rod 300 and a nut 500 threadedly connected to the positioning rod 300 .

[0048] Specifically, the two fasteners are a protrusion 400 and a nut 500. The protrusion 400 is arranged on the backlight side of the photovoltaic cell 100 and is integrally connected to the positioning rod 300. The nut 500 is arranged on the light-receiving side of the photovoltaic cell 100. The protrusion 400 abuts against the adjacent ends of the cross arm 201 of two of the frame profiles 200 located on the backlight side of the photovoltaic cell 100, and the nut 500 abuts against the adjacent ends of the cross arm 201 of two of the frame profiles 200 located on the light-receiving side of the photovoltaic cell 100.

[0049] During assembly, the positioning rod 300 is passed through the photovoltaic cell 100 from the backlight side of the photovoltaic cell 100, and the protruding plate 400 integrally connected to the positioning rod 300 is abutted against the cross arms 201 on the two frame profiles 200 on the backlight side of the photovoltaic cell 100. Then, the nut 500 is screwed into the end of the positioning rod 300 so that the nut 500 is close to the light-receiving side of the photovoltaic cell 100, and finally the nut 500 is abutted against the adjacent ends of the cross arms 201 of the two frame profiles 200 on the light-receiving side of the photovoltaic cell 100. Finally, the nuts 500 and the protruding plate 400 in the three fastening components cooperate with each other to clamp the two cross arms 201 of the frame profile 200, and the same pair of nuts 500 and protruding plate 400 can act on the two adjacent frame profiles 200 at the same time, thereby ensuring the stability of the special-shaped component structure and preventing the frame profiles 200 from detaching from each other, so that the three frame profiles 200 are connected end to end in sequence to form a triangular frame structure.

[0050] In a preferred embodiment, an elastic pad 600 is provided between at least one of the two fasteners and the frame profile 200. More specifically, an elastic pad 600 is provided between the protruding plate 400 and the cross arm 201 on the backlight side of the photovoltaic cell 100, and between the nut 500 and the cross arm 201 on the light-receiving side of the photovoltaic cell 100. The elastic pad 600 includes but is not limited to a rubber pad, a silicone pad, a latex pad, or other elastically functioning clamping pad. The elastic pad 600 is an annular structure and is sleeved outside the positioning rod 300 to prevent the elastic pad 600 from detaching from the positioning rod 300. By arranging elastic pads 600 between the two cross arms 201 of the frame profile 200 and the protruding plates 400 and nuts 500 corresponding to the two cross arms 201, it can be ensured that the protruding plates 400 and the nuts 500 transmit the locking pressure to the two cross arms 201 through the two elastic pads 600. Through the elastic deformation of the elastic pads 600 themselves, the two side surfaces of one of the elastic pads 600 are respectively sealed and fitted with the protruding plates 400 and one of the cross arms 201, and the two side surfaces of the other elastic pad 600 are respectively sealed and fitted with the nuts 500 and the other cross arm 201, thereby ensuring the stability of the special-shaped component structure and avoiding the separation of the three frame profiles 200.

[0051] In a preferred embodiment, among the positioning rods 300 of the three fastening components, two adjacent positioning rods 300 are connected by a connecting rod 700; both ends of the connecting rod 700 are provided with sleeve holes 701, and the two ends of the connecting rod 700 are respectively sleeved on the outside of the two adjacent connecting rods 700 through the two sleeve holes 701.

[0052] Specifically, there are three connecting rods 700 in the present invention, and both ends of the connecting rods 700 are provided with sleeve holes 701. The sleeve holes 701 are through holes so that the two ends of the connecting rods 700 can be sleeved on the outside of the two positioning rods 300. The circumferential inner wall of the sleeve hole 701 is sealed and fitted with the circumferential outer edge of the positioning rods 300, so that after the two ends of the connecting rods 700 are sleeved on the two positioning rods 300, the distance between the two positioning rods 300 is limited and fixed. When the two ends of the three connecting rods 700 are sleeved on the outside of the positioning rods 300, a stable triangular structure is formed. In order to prevent the connecting rods 700 from blocking the photovoltaic cells 100 from receiving light, the connecting rods 700 are arranged on the backlight surface of the photovoltaic cells 100.

[0053] In a preferred embodiment, the photovoltaic cell 100 includes a cover plate 800, a first adhesive film layer 900, a battery layer 110, a second adhesive film layer 120 and a back plate 130 connected in sequence, the battery layer 110 includes a plurality of battery cells 111, the second adhesive film layer 120 is provided with a plurality of laying recesses 121 on the side facing away from the back plate 130, and the first adhesive film layer 900 is provided with a plurality of clamping recesses 901 on the side facing away from the cover plate 800. 121 are arranged opposite to each other and combined to form a positioning cavity that corresponds to and matches the battery cell 111 one by one; the cover plate 800, the first film layer 900, the second film layer 120 and the back plate 130 are respectively provided with a first positioning hole 801, a second positioning hole 902, a third positioning hole 122 and a fourth positioning hole 131, and the first positioning hole 801, the second positioning hole 902, the third positioning hole 122 and the fourth positioning hole 131 are sealed and plugged together through the positioning rod 300.

[0054] Specifically, such as Figure 6-Figure 8 As shown, there are three first positioning holes 801 on the cover plate 800, three second positioning holes 902 on the first adhesive film layer 900, three third positioning holes 122 on the second adhesive film layer 120, and three third positioning holes 122 on the back plate 130, which are respectively located at the triangular positions of the photovoltaic cell 100, the second positioning hole 902 is separated from the clamping recess 901, and the third positioning hole 122 is separated from the laying recess 121. The first positioning hole 801, the second positioning hole 902, the third positioning hole 122 and the fourth positioning hole 131 are sealed and plugged together by the positioning rod 300, so that when they are stacked and connected, the cover plate 800, the first adhesive film layer 900, the second adhesive film layer 120 and the back plate 130 are aligned to prevent offset.

[0055] Laying recesses 121 are provided on the second adhesive film layer 120, with each recess 121 spaced apart. These recesses facilitate positioning of the cells 111 and prevent them from contacting and causing overlap during lamination. The clamping recesses 901 on the first adhesive film layer 900 cooperate with the laying recesses 121 to form a positioning cavity that fits the cells 111. This helps reduce the overall thickness and weight of the photovoltaic cell 100, making it easier to assemble and transport.

[0056] In a preferred embodiment, notches 203 are provided at both ends of the two cross arms 201 of the three frame profiles 200, and the inner walls of the notches 203 are aligned with the circumferential outer edges of the positioning rods 300. Specifically, the notches 203 are arc-shaped and adapted to the positioning rods 300. With the above structure, when the nut 500 and the protruding plate 400 are clamped together, the contact area between one elastic pad 600 and the cross arm 201 on the light-receiving side of the photovoltaic cell 100, as well as the contact area between the other elastic pad 600 and the cross arm 201 on the backlight side of the photovoltaic cell 100, is increased, thereby facilitating the tightening of the protruding plate 400 and the nut 500 to the frame profile 200.

[0057] According to the above-mentioned special-shaped components, the present invention also discloses a photovoltaic power generation device, such as Figures 9-14 As shown, it includes six of the above-mentioned special-shaped components, among the six frame profiles 200 of two adjacent special-shaped components, the two ends of the frame profiles 200 are flush, the two frame profiles 200 fit each other and the openings of the two frame profiles 200 are set back to back, and the two special-shaped components are detachably connected by a connecting component.

[0058] Specifically, the special-shaped components are arranged in a circular array, each having the same structure. The circumferential outer edges of the six special-shaped components have one overlapping side. When the six special-shaped components are placed horizontally, the horizontal projections of the six special-shaped components combine to form a regular hexagon. The six special-shaped components are detachably connected via a connecting component.

[0059] In the above photovoltaic power generation device, the number of special-shaped components is not limited to six, and can also be other multiple numbers. It is only necessary to ensure that among the six frame profiles 200 of two adjacent special-shaped components, there is a pair of frame profiles 200 with flush ends, the openings are set back to back, and the vertical arms 202 of the pair of frame profiles 200 are in contact with the side away from the corresponding photovoltaic cell 100. After meeting the above requirements, according to the number of special-shaped components, photovoltaic power generation devices of different shapes can be spliced ​​to meet the requirements of paving surfaces of various shapes. For example, when there are two special-shaped components, such as Figure 10 As shown, the end shape of the circumferential outer edge of the photovoltaic power generation device is a parallelogram. When there are three special-shaped components, as shown in Figure 15As shown, the end shape of the circumferential outer edge of the photovoltaic power generation device is an isosceles trapezoid. When there are four special-shaped components, as shown in Figure 16 The end shape of the circumferential outer edge of the photovoltaic power generation device shown is an arrow shape; when there are six special-shaped components, the end shape of the circumferential outer edge of the photovoltaic power generation device is a regular hexagon, and when connected with other photovoltaic power generation devices composed of the same six special-shaped components, a honeycomb structure can be formed. Whether it is a regular hexagon, a parallelogram, a trapezoid or an arrow shape, the photovoltaic power generation device can be connected to other photovoltaic power generation devices composed of special-shaped components with the same or different structures to form different shapes. While performing photovoltaic power generation, it has different aesthetic decorative effects on the roof of the building. Since the special-shaped components are detachably connected through the connecting components, it is convenient to adjust the number of special-shaped components, thereby changing the overall appearance of the photovoltaic power generation device to match the corresponding decoration of the top of the building. In addition, the frame profile 200 of the special-shaped component does not need to be provided with a cavity, so the production material is reduced, the production cost is reduced, and the weight is reduced, thereby reducing the burden of handling and assembly, which is conducive to improving installation efficiency.

[0060] In a preferred embodiment, the positioning rods 300 connected to the two frame profiles 200 are all positioning tubes, and the connecting component includes a connecting frame 140 arranged on the backlight surface of the two adjacent special-shaped components. The connecting frame 140 is provided with a hook 150 that corresponds one-to-one to the positioning tubes of the two adjacent special-shaped components and is snap-fitted; the hook 150 is detachably arranged on the connecting frame 140.

[0061] Specifically, the positioning rods 300 in each special-shaped component are all positioning tubes, and the hook 150 includes a limiting plate 153. The same side of the limiting plate 153 is vertically connected to two hook rods 152 distributed side by side, and the two hook rods 152 are respectively connected to the two hook heads 151 at one end away from the limiting plate 153; the connecting frame 140 is annular, and six strip openings 141 are distributed on the connecting frame 140. The strip openings 141 extend along the radial direction of the disc. The strip openings 141 are through holes, and the connecting frame 140 is arranged on the backlight side of the special-shaped component; the limiting plate 153 abuts against the side of the connecting frame 140 away from the special-shaped component, and the two hook rods 152 of the hook 150 are respectively sealed with the inner walls of the two ends of the strip opening 141, and the two hook rods 152 are passed through the inner side of the positioning tube, and the hook head 151 abuts against the end of the positioning tube away from the limiting plate 153, and the special-shaped component is clamped between the hook head 151 and the connecting frame 140.

[0062] After adopting the above structure, the hook 150 can be conveniently connected to the connecting frame 140 in a detachable manner through the strip opening 141 on the connecting frame 140. According to the number of special-shaped components in the photovoltaic power generation device, the hook 150 can be inserted into the same number of strip openings 141 of the connecting frame 140. After the hook head 151 is passed through the positioning tube of the special-shaped component, the special-shaped component is clamped on the connecting frame 140, which not only realizes the detachable connection of the special-shaped component through the connecting frame 140, but also facilitates the adjustment of the number of hooks 150 on the connecting frame 140 according to the number of special-shaped components. It is easy to assemble and use, and ensures the overall aesthetics of the photovoltaic power generation device.

[0063] In a preferred embodiment, the connecting component also includes a locking bolt 160 extending along the thickness direction of the two adjacent special-shaped components. The locking bolt 160 is threadedly connected to the connecting frame 140, and the two adjacent special-shaped components are clamped between the locking bolt 160 and the hook heads 151 of the two hooks 150.

[0064] Specifically, the locking bolt 160 is connected to the connecting frame 140 coaxially, and a threaded tube 142 is integrally connected to the inner side of the connecting frame 140. The threaded tube 142 is threadedly connected to the locking bolt 160. A pressure plate 170 is provided between the connecting frame 140 and the special-shaped component. A positioning sleeve 171 is provided on the side of the pressure plate 170 adjacent to the connecting frame 140. The pressure plate 170 is clamped between the end of the locking bolt 160 and the special-shaped component, and the positioning sleeve 171 is sleeved on the end of the locking bolt 160.

[0065] After adopting the above structure, when connecting the connecting frame 140 to the special-shaped component, the hook 150 passes through the strip-shaped opening 141 and the positioning tube of the special-shaped component in sequence, and then the locking bolt 160 is screwed into the inner side of the threaded tube 142, and the locking bolt 160 is leaned against the special-shaped component. The end of the locking bolt 160 is located in the positioning sleeve 171. As the distance between the end of the locking bolt 160 and the special-shaped component is reduced, the locking bolt 160 finally pushes the pressure plate 170 to move, and the pressure plate 170 is tightened. 0 is locked on the special-shaped component, and at the same time, the hook head 151 of the hook 150 abuts against the end of the positioning tube on the light-receiving side of the photovoltaic cell 100. That is, at this time, the hook head 151 applies downward pressure to the special-shaped component, and the locking bolt 160 applies upward pressure to the special-shaped component through the pressure plate 170, finally achieving a firm connection between the special-shaped component and the connecting frame 140, preventing the special-shaped component from shaking and deviating on the connecting frame 140, thereby ensuring the stability of the overall structure of the photovoltaic power generation device.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
