DETAILED DESCRIPTION

[0025] The specific implementation of the present invention will be further described below through specific examples in conjunction with the accompanying drawings.

[0026] Embodiment 1: A heterogeneous photovoltaic reflective frame, such as Figure 1As shown, the main body of the photovoltaic module frame is composed of two mutually parallel first side frames 1 and two mutually parallel second side frames 3. The two ends of the first side frame 1 are respectively connected to the two ends of the second side frame 3. The adjacent first side frames 1 and second side frames 3 are perpendicular to each other, and the first side frames 1 and second side frames 3 are not bent as a whole, so as to form a rectangular frame. The photovoltaic module is arranged in the photovoltaic module frame and fixed by the photovoltaic module frame. A first reflective convex sheet 2 is arranged on the first side frame 1, and a second reflective convex sheet 4 is arranged on the second side frame 3. The length of the first reflective convex sheet 2 is less than the length of the first side frame 1, and the length of the second reflective convex sheet 4 is less than the length of the second side frame 3. The first reflective convex sheet 2 and the second reflective convex sheet 4 are both arranged on the side of the first side frame 1 and the second side frame 3 facing upward, and the first reflective convex sheet 2 and the second reflective convex sheet 4 play the role of reflecting light. The surfaces of the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3 are all covered with a layer of metal reflective film 17 by electroplating, which can improve the emissivity of light transmitted from the front of the photovoltaic panel assembly, reflected from the ground to the back glass, and refracted to the frame structure, i.e., the inner side of the first side frame 1 and the second side frame 3, so that the light is re-reflected to the back battery cell for power generation, thereby improving the overall power generation of the photovoltaic assembly. The first reflective convex sheet 2 and the second reflective convex sheet 4 are rectangular in shape, and the angle of the reflected light can be adjusted by adjusting the angle of the first reflective convex sheet 2 and the second reflective convex sheet 4, thereby improving the intensity of the light reflected to the back battery cell. When in use, by coating the outer walls of the first side frame 1 and the second side frame 3 that constitute the photovoltaic frame structure with a layer of metal reflective film 17, the reflectivity can be increased, and the light that is transmitted from the front of the corresponding photovoltaic panel assembly, reflected from the ground to the rear glass, and then refracted to the inner side of the frame structure, i.e., the first side frame 1 and the second side frame 3, can be reflected again to the rear battery cell, thereby increasing the overall power of the photovoltaic assembly. Secondly, by respectively installing the first side frame 1 and the second side frame 3 on one side, the first side frame 1 and the second side frame 3 respectively, the light reflection area can be increased, thereby facilitating the increase of the light reflected on the rear battery cell, and further improving the reflective reuse effect of the photovoltaic frame structure.

[0027] like Figure 2As shown, the two ends of the first reflective convex piece 2 are respectively connected to the adjustment seat 12, and a damping shaft 15 is provided at the connection between the first reflective convex piece 2 and the adjustment seat 12. The adjustment seat 12 fixes the position of the first reflective convex piece 2, and the damping shaft 15 can achieve the angle adjustment and fixation of the first reflective convex piece 2. A fixing plate 14 is welded on the adjustment seat 12, and the fixing plate 14 is half-waisted, saving materials, and the overall size of the fixing plate 14 matches the width of the first side frame 1, ensuring that the adjustment seat 12 and the fixing plate 14 are located within the range of the first side frame 1 when fixed. There are two fixing holes on the fixing plate 14, and the fixing of the adjustment seat 12 and the first side frame 1 is achieved by two screws. The fixing structure of the second reflective convex piece 4 is similar to the fixing structure of the first reflective convex piece 2. The two ends of the second reflective convex piece 4 are also connected to the two adjustment seats 12, and a damping shaft 15 is also provided at the connection between the second reflective convex piece 4 and the adjustment seat 12, and the damping shaft 15 is used to adjust and fix the angle of the second reflective convex piece 4. The adjustment seat 12 connected to the second reflective convex piece 4 is also fixed by the fixing piece 14. Since the width of the first side frame 1 is equal to the width of the second side frame 3, the size specifications of the adjustment seat 12 and the fixing piece 14 can be equal to the size specifications of the adjustment seat 12 and the fixing piece 14 on the first side frame 1. The adjustment seat 12 and the fixing piece 14 are fixed by two screws, thereby fixing the second reflective convex piece 4. Since the first reflective convex piece 2 and the first side frame 1, and the second reflective convex piece 4 and the second side frame 3 are fixed by the fixing seat and the fixing piece 14 with screws, when the first reflective convex piece 2 or the second reflective convex piece 4 fails and needs to be repaired, the first reflective convex piece 2 or the second reflective convex piece 4 can be disassembled separately for repair or replacement, which is more flexible.

[0028] A group of mounting pieces 13 are respectively provided at the positions where the second side frame 3 is fixedly connected to the first side frame 1. The mounting pieces 13 are semicircular in shape, and the diameter at the widest part is equal to the width of the first side frame 1. Two fixing holes are provided thereon for fixing screws. When fixing the first side frame 1 and the second side frame 3, the first side frame 1 is extended into the space formed by the mounting pieces 13 which are opposite to each other, the fixing holes punched in advance on the first side frame 1 are aligned with the fixing holes on the mounting pieces 13, and the two screws are respectively fixed on the upper and lower sides, thereby fixing the first side frame 1 and the second side frame 3. By assembling the short frame with sawtooth corner codes and the long side with rivet points into one body, the photovoltaic frame structure with an interlocking structure is replaced with a structure assembled by two first side frames 1 and two second side frames 3 through mounting pieces 13 and screws, so that the photovoltaic component frame structure is easy to disassemble and maintain between photovoltaic panel components, and has higher flexibility.

[0029] like Figure 3As shown, the inner side of the metal reflective film 17 electroplated on the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3 is provided with an aluminum alloy base layer 16, that is, the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3 are formed with aluminum alloy inside the main frame, and the metal reflective film 17 is electroplated outside the aluminum alloy main frame. The aluminum alloy base layer 16 can ensure the overall structural strength of the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3, and improve the safety of the overall photovoltaic module.

[0030] Embodiment 2: The photovoltaic module frame body in this embodiment is composed of two mutually parallel first side frames 1 and two mutually parallel second side frames 3. The two ends of the first side frame 1 are respectively connected to the two ends of the second side frame 3. The adjacent first side frames 1 and second side frames 3 are perpendicular to each other, and the first side frames 1 and second side frames 3 are not bent as a whole, so as to form a rectangular frame. The photovoltaic module is arranged in the photovoltaic module frame and fixed by the photovoltaic module frame. A first reflective convex sheet 2 is arranged on the first side frame 1, and a second reflective convex sheet 4 is arranged on the second side frame 3. The length of the first reflective convex sheet 2 is less than the length of the first side frame 1, and the length of the second reflective convex sheet 4 is less than the length of the second side frame 3. The first reflective convex sheet 2 and the second reflective convex sheet 4 are both arranged on the side of the first side frame 1 and the second side frame 3 facing upward, and the first reflective convex sheet 2 and the second reflective convex sheet 4 play the role of reflecting light. The surfaces of the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3 are all covered with a layer of metal reflective film 17 by electroplating, which can improve the emissivity of light transmitted from the front of the photovoltaic panel assembly, reflected from the ground to the back glass, and refracted to the frame structure, i.e., the inner side of the first side frame 1 and the second side frame 3, so that the light is re-reflected to the back battery cell for power generation, thereby improving the overall power generation of the photovoltaic assembly. The first reflective convex sheet 2 and the second reflective convex sheet 4 are rectangular in shape, and the angle of the reflected light can be adjusted by adjusting the angle of the first reflective convex sheet 2 and the second reflective convex sheet 4, thereby improving the intensity of the light reflected to the back battery cell. When in use, by coating the outer walls of the first side frame 1 and the second side frame 3 that constitute the photovoltaic frame structure with a layer of metal reflective film 17, the reflectivity can be increased, and the light that is transmitted from the front of the corresponding photovoltaic panel assembly, reflected from the ground to the rear glass, and then refracted to the inner side of the frame structure, i.e., the first side frame 1 and the second side frame 3, can be reflected again to the rear battery cell, thereby increasing the overall power of the photovoltaic assembly. Secondly, by respectively installing the first side frame 1 and the second side frame 3 on one side, the first side frame 1 and the second side frame 3 respectively, the light reflection area can be increased, thereby facilitating the increase of the light reflected on the rear battery cell, and further improving the reflective reuse effect of the photovoltaic frame structure.

[0031] like Figure 2As shown, the two ends of the first reflective convex piece 2 are respectively connected to the adjustment seat 12, and a damping shaft 15 is provided at the connection between the first reflective convex piece 2 and the adjustment seat 12. The adjustment seat 12 fixes the position of the first reflective convex piece 2, and the damping shaft 15 can achieve the angle adjustment and fixation of the first reflective convex piece 2. A fixing plate 14 is welded on the adjustment seat 12, and the fixing plate 14 is half-waisted, saving materials, and the overall size of the fixing plate 14 matches the width of the first side frame 1, ensuring that the adjustment seat 12 and the fixing plate 14 are located within the range of the first side frame 1 when fixed. There are two fixing holes on the fixing plate 14, and the fixing of the adjustment seat 12 and the first side frame 1 is achieved by two screws. The fixing structure of the second reflective convex piece 4 is similar to the fixing structure of the first reflective convex piece 2. The two ends of the second reflective convex piece 4 are also connected to the two adjustment seats 12, and a damping shaft 15 is also provided at the connection between the second reflective convex piece 4 and the adjustment seat 12, and the damping shaft 15 is used to adjust and fix the angle of the second reflective convex piece 4. The adjustment seat 12 connected to the second reflective convex piece 4 is also fixed by the fixing piece 14. Since the width of the first side frame 1 is equal to the width of the second side frame 3, the size specifications of the adjustment seat 12 and the fixing piece 14 can be equal to the size specifications of the adjustment seat 12 and the fixing piece 14 on the first side frame 1. The adjustment seat 12 and the fixing piece 14 are fixed by two screws, thereby fixing the second reflective convex piece 4. Since the first reflective convex piece 2 and the first side frame 1, and the second reflective convex piece 4 and the second side frame 3 are fixed by the fixing seat and the fixing piece 14 with screws, when the first reflective convex piece 2 or the second reflective convex piece 4 fails and needs to be repaired, the first reflective convex piece 2 or the second reflective convex piece 4 can be disassembled separately for repair or replacement, which is more flexible.

[0032] A group of mounting pieces 13 are respectively provided at the positions where the second side frame 3 is fixedly connected to the first side frame 1. The mounting pieces 13 are semicircular in shape, and the diameter at the widest part is equal to the width of the first side frame 1. Two fixing holes are provided thereon for fixing screws. When fixing the first side frame 1 and the second side frame 3, the first side frame 1 is extended into the space formed by the mounting pieces 13 which are opposite to each other, the fixing holes punched in advance on the first side frame 1 are aligned with the fixing holes on the mounting pieces 13, and the two screws are respectively fixed on the upper and lower sides, thereby fixing the first side frame 1 and the second side frame 3. By assembling the short frame with sawtooth corner codes and the long side with rivet points into one body, the photovoltaic frame structure with an interlocking structure is replaced with a structure assembled by two first side frames 1 and two second side frames 3 through mounting pieces 13 and screws, so that the photovoltaic component frame structure is easy to disassemble and maintain between photovoltaic panel components, and has higher flexibility.

[0033] like Figure 3As shown, the inner side of the metal reflective film 17 electroplated on the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3 is provided with an aluminum alloy base layer 16, that is, the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3 are formed with aluminum alloy inside the main frame, and the metal reflective film 17 is electroplated outside the aluminum alloy main frame. The aluminum alloy base layer 16 can ensure the overall structural strength of the first reflective convex sheet 2, the second reflective convex sheet 4, the first side frame 1, and the second side frame 3, and improve the safety of the overall photovoltaic module.

[0034] like Figure 4 As shown, a second photovoltaic panel assembly slot 5 is provided on the opposite side of the two second side frames 3, and the second photovoltaic panel assembly slot 5 is formed by a U-shaped limit frame, and the opening of the U-shaped limit frame faces the side facing upward when the photovoltaic assembly is installed. The length of the second photovoltaic panel assembly slot 5 formed therein is equal to the length of the photovoltaic assembly to be installed, and the height of the second photovoltaic panel assembly slot 5 is greater than or equal to the thickness of the photovoltaic assembly to be installed, ensuring that the second photovoltaic panel assembly slot 5 can accommodate the assembly to be installed. A long strip of second anti-skid pressing plate 7 is provided in the second photovoltaic panel assembly slot 5, and the size of the second anti-skid pressing plate 7 is smaller than the size of the second photovoltaic panel assembly slot 5. The second anti-skid pressing plate 7 is fixedly connected to the second photovoltaic panel assembly slot 5 by a number of evenly arranged second springs 6. When the photovoltaic assembly is installed, the photovoltaic assembly squeezes the second anti-skid pressing plate 7, thereby compressing the second spring 6. When the photovoltaic assembly is fixed, the second spring 6 compresses the second anti-skid pressing plate 7, thereby pressing the photovoltaic assembly tightly and improving the firmness between the photovoltaic assembly and the photovoltaic assembly frame.

[0035] like Figure 5 As shown, a first photovoltaic panel assembly slot 11 is provided on the opposite sides of the two first side frames 1, and a protruding edge is provided at the bottom of the first photovoltaic panel assembly slot 11 as a fixed edge. The length of the first photovoltaic panel assembly slot 11 is equal to the length of the photovoltaic component to be installed, and the height of the first photovoltaic panel assembly slot 11 is greater than or equal to the thickness of the photovoltaic component to be installed, so as to ensure that the first photovoltaic panel assembly slot 11 can accommodate the component to be installed. A long strip-shaped first anti-skid pressure plate 9 is provided in the first photovoltaic panel assembly slot 11, and the size of the first anti-skid pressure plate 9 is smaller than the size of the first photovoltaic panel assembly slot 11. The first anti-skid pressure plate 9 is fixedly connected to the first photovoltaic panel assembly slot 11 by a plurality of evenly arranged first springs 10. When installing the photovoltaic component, the photovoltaic component squeezes the first anti-skid pressure plate 9, thereby compressing the first spring 10. When the photovoltaic component is fixed, the first spring 10 compresses the first anti-skid pressure plate 9, thereby pressing the photovoltaic component tightly and improving the firmness between the photovoltaic component and the photovoltaic component frame.

[0036] By installing the first photovoltaic panel assembly slot 11 and the like, when the photovoltaic frame structure is specifically utilized, after the user inserts the photovoltaic panel assembly into the first photovoltaic panel assembly slot 11 and the second photovoltaic panel assembly slot 5 for inserting the photovoltaic panel assembly which are correspondingly arranged inside the first side frame 1 and the second side frame 3, the first anti-skid pressure plate 9 connected by the first spring 10 inside the first photovoltaic panel assembly slot 11 and the second anti-skid pressure plate 7 connected by the second spring 6 inside the second photovoltaic panel assembly slot 5 will, under the action of the potential energy of the spring structure, push the first anti-skid pressure plate 9 and the second anti-skid pressure plate 7 to press the photovoltaic panel assembly, thereby improving the firmness of the photovoltaic frame structure and the photovoltaic panel assembly after assembly.

[0037] The first side frame 1 is also provided with docking blocks 8 at both ends, and a docking groove of matching size is provided at the corresponding position of the second side frame 3. When the first side frame 1 and the second side frame 3 are fixed, the grounding blocks are inserted into the docking grooves, thereby improving the connection strength between the first side frame 1 and the second side frame 3 during the card assembly and splicing, thereby improving the structural strength of the overall photovoltaic module frame.

[0038] like Figure 6 As shown, the light transmitted from the front of the photovoltaic panel assembly, reflected from the ground to the back glass, and then refracted to the first side and the first reflective convex piece 2 will be reflected again due to the presence of the metal reflective film 17. The reflection path is shown in the figure. When the angle of the first reflective convex piece 2 is adjusted to a suitable position, the emitted light can be concentrated on the back cell sheet, so that it can be utilized again, thereby improving the power generation efficiency of the overall photovoltaic assembly.

[0039] like Figure 7 As shown, this is the light emission path of the second side frame 3 and the second reflective convex sheet 4. Combined with the first side frame 1 and the first reflective convex sheet 2, by adjusting the angles of the first reflective convex sheet 2 and the second reflective convex sheet 4, the reflected light that cannot be used on the frame can be reflected to the back battery cell, providing a certain source of light energy for the photovoltaic module and improving the overall power generation efficiency of the photovoltaic module.

[0040] When the original photovoltaic module frame that has not been coated with a metal emission film is used, its reflection efficiency for light is extremely low, and only about 10% of the light is emitted to the rear battery cell. However, by arranging a first reflective convex piece 2 and a second reflective convex piece 4 with adjustable angles on the photovoltaic module frame, and electroplating a metal reflective film 17 on the surface of the first side frame 1, the second side frame 3, the first reflective convex piece 2 and the second reflective convex piece 4, 80% or more of the light reflected on the frame can be reflected to the rear battery cell, which greatly improves the utilization rate of the light reflected on the frame and improves the overall power generation efficiency of the photovoltaic module.

[0041] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
