[0050] In order to thoroughly understand the present invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by the present invention. The optional embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0051] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0052] The present application embodiment provides a photovoltaic panel structure, referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 The photovoltaic panel structure includes: a first photovoltaic panel 11, a second photovoltaic panel 12, a shell 23 and a support member; wherein the first photovoltaic panel 11 and the second photovoltaic panel 12 are stacked; the first photovoltaic panel 11 is connected to the shell 23; the shell 23 is provided with a guide rail 22, and the second photovoltaic panel 12 is slidably assembled on the guide rail 22, so that the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11 or at least the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11; the support member is connected to the shell 23, and the support member is configured to support the second photovoltaic panel 12 when at least part of the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11.

[0053] In the above scheme, in the stacked photovoltaic panel structure including the first photovoltaic panel 11 and the second photovoltaic panel 12, by connecting the support member to the housing 23, when at least part of the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11, the support member supports the second photovoltaic assembly, thereby improving the support stability of the second photovoltaic panel 12. The above structures are described in detail below in conjunction with the accompanying drawings.

[0054] When the first photovoltaic panel 11 and the second photovoltaic panel 12 are arranged, the first photovoltaic panel 11 is a photovoltaic panel with a fixed position. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8, the first photovoltaic panel 11 is connected to the shell 23. Exemplarily, the specific fixing method can be that a support beam 21 is provided on the shell 23, and the first photovoltaic panel 11 is fixedly connected to the support beam 21. The second photovoltaic panel 12 is a photovoltaic panel that can slide. Specifically, a guide rail 22 is provided on the shell 23. Exemplarily, the guide rail 22 can be fixed to the shell 23 by means of screw fastening, clamping, etc. The second photovoltaic panel 12 is slidably assembled on the guide rail 22, so that the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11 or at least the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11. Exemplarily, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 , the first photovoltaic panel 11 and the second photovoltaic panel 12 can be stacked, and the first photovoltaic panel 11 is arranged above the second photovoltaic panel 12. Exemplarily, when the second photovoltaic panel 12 is retracted into the guide rail 22, the second photovoltaic panel 12 completely overlaps with the first photovoltaic panel 11, and the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11. When at least part of the second photovoltaic panel 12 extends outward, part of the second photovoltaic panel 12 overlaps with the first photovoltaic panel 11, and another part of the second photovoltaic panel 12 overlaps with the first photovoltaic panel 11. Not only can the first photovoltaic panel 11, which is fixed in position, protect the second photovoltaic panel 12; but also part of the second photovoltaic panel 12 can be extended to stagger the position of the first photovoltaic panel 11, so that the second photovoltaic panel 12 can also be irradiated by sunlight, thereby generating electricity.

[0055] For example, Figure 1 The figure shows a partial side view of the second photovoltaic panel 12 extending 1150 mm outward from the first photovoltaic panel 11. The second photovoltaic panel 12 can also be completely retracted under the first photovoltaic panel 11, so that only the first photovoltaic panel 11 can receive sunlight, and the second photovoltaic panel 12 can no longer receive sunlight.

[0056] Exemplarily, the two support beams 21 can be respectively located above the two guide rails 22, so that when the two photovoltaic panel assemblies are respectively mounted on the two support beams 21 and the two guide rails 22, the first photovoltaic panel 11 is located above the second photovoltaic panel 12. Of course, in other embodiments, the first photovoltaic panel 11 can also be arranged below the second photovoltaic panel 12. In this case, the support beam 21 can be located below the guide rail 22, so that when the two photovoltaic panels are respectively mounted on the support beam 21 and the guide rail 22, the second photovoltaic panel 12 is located above the first photovoltaic panel 11. By stacking the two photovoltaic panels, one of which can be extended or retracted, two different power generation modes are provided.

[0057] When setting up each photovoltaic panel, the photovoltaic panel includes Figure 1 , Figure 2 and Figure 3 The honeycomb grid filling area is the photovoltaic panel lighting and photoelectric conversion area, and the main material is formed by tempered glass lamination process. Figure 2 The dotted line in the figure is a hidden diagram of the transmission mechanism 62 and the motor 61 when the second photovoltaic panel 12 is in the retracted state, and the area selected by the thin dotted line is the layout diagram of the bottom layer of the photovoltaic panel. Figure 3 Schematic diagram of the second photovoltaic panel 12 extending outward, the main substrate of the second photovoltaic panel 12 is a polymer flexible composite board, the honeycomb grid filling area is the photovoltaic panel lighting and photoelectric conversion area, and the photovoltaic panel structure is in a high-power power generation mode. The thin dotted line is a hidden diagram of the transmission mechanism 62 and the motor 61 when the second photovoltaic panel 12 is in the extended state, and the double-dotted line is the transmission soft shaft component in the transmission mechanism 62.

[0058] When the housing 23 is provided, the housing 23 is used as a carrier for providing two photovoltaic panels, and the housing 23 may adopt a frame structure, a plate structure, etc. as a supporting structure, but not limited to the frame structure. Figure 2 , Figure 5 and Figure 7 , a support beam 21 is connected to the shell 23, and the first photovoltaic panel 11 is fixedly connected to the support beam 21 to fix the first photovoltaic panel 11. Exemplarily, the number of the support beams 21 can be two, and the two support beams 21 are distributed at intervals. The first photovoltaic panel 11 has two third sides 111 that are opposite to each other, and the two third sides 111 are respectively fixed to the two support beams 21. In some embodiments, the two support beams 21 can be parallel and distributed at intervals, and the two third sides 111 of the first photovoltaic panel 11 are also parallel and distributed at intervals, so that the two third sides 111 of the first photovoltaic panel 11 are respectively fixed to the two support beams 21. A variety of specific fixing methods can be used. Exemplarily, the two third sides 111 of the first photovoltaic panel 11 can be fixed to the two support beams 21 respectively by gluing, clamping, etc. Exemplarily, the first photovoltaic panel 11 includes a flexible photovoltaic power generation area and a frame wrapped around the edge of the photovoltaic power generation area. The structure of the frame can be a side sheet metal. The frame can support and unfold and fix the photovoltaic power generation area. The third frames at the two third sides 111 can be fixed on the two support beams 21 respectively.

[0059] refer to Figure 2 , Figure 5 ,and Figure 7, the second photovoltaic panel 12 is slidably mounted on the guide rail 22, so that the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11 or at least the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11. That is, the second photovoltaic panel 12 can slide outward along the guide rail 22, so that at least part of the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11. The second photovoltaic panel 12 can also be retracted inward along the guide rail 22, so that the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11.

[0060] Exemplary, reference Figure 2 , Figure 5 and Figure 7 , the number of guide rails 22 can be two, the two guide rails 22 are parallel and spaced apart, and the two opposite first side edges 121 on the second photovoltaic panel 12 are respectively slidably assembled on the two guide rails 22. That is, the photovoltaic panel structure also has two guide rails 22 that are parallel and spaced apart, and the two opposite first side edges 121 of the second photovoltaic panel 12 are respectively slidably assembled in the two guide rails 22, so that the second photovoltaic panel 12 can slide in the guide rail 22 along the extension direction of the guide rail 22. When used, the second photovoltaic panel 12 can slide out along the guide rail 22 to a position where at least part of the area is staggered from the first photovoltaic panel 11, so that the part of the second photovoltaic panel 12 that extends outward can also receive sunlight and generate electricity. The second photovoltaic panel 12 can also slide along the guide rail 22 to a position that completely overlaps with the first photovoltaic panel 11, so that the first photovoltaic panel 11 shields the second photovoltaic panel 12, so that only the first photovoltaic panel 11 can receive sunlight. Of course, in other embodiments, the number of the guide rail 22 may be one, and only one first side edge 121 of the second photovoltaic panel 12 may be slidably assembled in the guide rail 22 .

[0061] When realizing the sliding assembly between the second photovoltaic panel 12 and the guide rail 22, a variety of methods can be used. Exemplarily, the first side edge 121 of the second photovoltaic panel 12 is provided with a first frame 122, the guide rail 22 has a guide rail 22 groove, and the first frame 122 is slidably assembled in the guide rail 22 groove, so that the second photovoltaic panel 12 can slide reliably and stably in the guide rail 22 groove, thereby improving the reliable stability of sliding. Exemplarily, when the number of guide rails 22 is two, a guide rail 22 groove can be provided in each guide rail 22, so that the first frame 122 on each of the two first side edges 121 of the second photovoltaic panel 12 can be slidably assembled in the corresponding guide rail 22 groove.

[0062] Exemplary, reference Figure 1 , Figure 3 , Figure 5 and Figure 7, the two first side edges 121 of the second photovoltaic panel 12 can be respectively provided with two first frames 122, and the two first frames 122 fix the photovoltaic panel in the second photovoltaic panel 12 at the middle position of the second photovoltaic panel 12. Exemplarily, each guide rail 22 can have a guide rail 22 groove, and the notches of the guide rail 22 grooves of the two guide rails 22 are arranged relatively, and the two first frames 122 on the second photovoltaic panel 12 are respectively accommodated in the two guide rail 22 grooves, so that each first frame 122 on the second photovoltaic panel 12 can slide in the guide rail 22 groove. Of course, the setting method of the guide rail 22 is not limited to the method shown above, and other methods can also be used.

[0063] In addition, a support member is connected to the housing 23, and the support member is used to support the second photovoltaic panel 12 when at least part of the second photovoltaic panel 12 extends outward from the first photovoltaic panel 11. That is, when at least part of the second photovoltaic panel 12 extends outward, the support member can support and fix the second photovoltaic panel 12, so that the second photovoltaic panel 12 is fixed in a manner similar to a cantilever beam, thereby improving the support stability of the second photovoltaic panel 12 and preventing the second photovoltaic panel 12 from being deformed by strong winds, thereby improving the adaptability of the photovoltaic panel structure to various application environments.

[0064] When setting the support, various structural modes that can cantilever support the extended second photovoltaic panel 12 can be adopted. Figure 4 and Fig. 9 , the support member can be arranged at the entrance of the guide rail 22, so that when the second photovoltaic panel 12 extends outward from the entrance of the guide rail 22, the support member can be connected between the part of the second photovoltaic panel 12 that does not extend out and the guide rail 22, so as to cantilever support the extended part of the second photovoltaic panel 12, and can also make the extended part of the second photovoltaic panel 12 longer, increase the area of ​​the second photovoltaic panel 12 irradiated by sunlight when it extends, and thus increase the power generation power of the second photovoltaic panel 12. Of course, in other embodiments, the support member can be arranged at the middle position of the guide rail 22. Regarding the number of support members, it can be one or more. Exemplarily, the number of support members can be two, each support member corresponds to a guide rail 22 and is arranged at the entrance of the corresponding guide rail 22. Of course, in other embodiments, the number of support members can be one or more. One or more support members can be connected to each guide rail 22. There are many ways to set the support member. The following takes the setting method of a support member as an example to introduce several exemplary ways of setting the support member.

[0065] Exemplary, reference Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8, the support member may include: a reinforcing plate 30 disposed at the entrance of the guide rail 22 groove of the guide rail 22. The reinforcing plate 30 has a slide groove 31. The first side 121 of the second photovoltaic panel 12 is provided with a first frame 122, and the first frame 122 is slidably assembled in the slide groove 31. The reinforcing plate 30 may be configured to support the second photovoltaic panel 12 when at least part of the second photovoltaic panel 12 extends from the first photovoltaic panel 11. Exemplarily, the reinforcing plate 30 may be disposed at the entrance of the guide rail 22, that is, the reinforcing plate 30 is disposed at an end position of the guide rail 22. When at least part of the second photovoltaic panel 12 extends from the first photovoltaic panel 11, the reinforcing plate 30 can support the second photovoltaic panel 12, thereby improving the support stability of the second photovoltaic panel 12 when it extends. The reinforcing plate 30 may be connected to the housing 23, or to the guide rail 22. Of course, the reinforcing plate 30 may also provide sliding support to the second photovoltaic panel 12 during the sliding process of the second photovoltaic panel 12 in the guide rail 22.

[0066] When the reinforcing plate 30 is provided, various methods may be used. Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The slide groove 31 of the reinforcing plate 30 has a first groove wall 311 and a second groove wall 312 in a first direction that are opposite to each other. The second photovoltaic panel 12 includes an upper surface and a lower surface. The upper surface of the second photovoltaic panel 12 refers to the surface of the second photovoltaic panel 12 facing upward after the assembly is completed, that is, Figure 1 The lower surface of the second photovoltaic panel 12 refers to the surface of the second photovoltaic panel 12 facing downward after the assembly is completed, that is, Figure 1 The surface facing downward in the first direction. A first frame 122 is provided on the first side of the guide rail 22 on the second photovoltaic panel 12. The portion of the first frame 122 placed on the lower surface is the first portion 131, that is, the surface of the first portion 131 is the lower surface of the first frame 122. The portion of the first frame 122 placed on the upper surface is the second portion 132, that is, the surface of the second portion 132 is the upper surface of the first frame 122. And when at least part of the second photovoltaic panel 12 extends outward relative to the first photovoltaic panel 11, the first portion 131 of the first frame 122 presses against the first groove wall 311 of the slide groove 31, and / or the second portion 132 of the first frame 122 presses against the second groove wall 312 of the slide groove 31.

[0067] Exemplarily, the first frame 122 has a lower surface and an upper surface that are relatively located in the first direction. The first direction is a direction perpendicular to the second photovoltaic panel 12. When at least part of the second photovoltaic panel is extended, the first portion 131 of the first frame 122 is used to press against the first groove wall 311 of the slide 31, and / or the second groove wall 312 of the slide 31 is used to press against the second portion 132 of the first frame 122. Exemplarily, the first groove wall 311 can be a lower groove wall during the support process of the support member, and the second groove wall 312 can be an upper groove wall during the support process of the support member. The first portion 131 of the first frame 122 can be a lower surface during the cantilever support process, which presses against the lower groove wall of the slide 31. The second portion 132 of the first frame 122 can be an upper surface during the cantilever support process. When the upper groove wall of the slide 31 presses against the second portion 132 of the first frame 122, the second photovoltaic panel 12 extending outward can be cantilevered, thereby improving the support stability of the second photovoltaic panel 12 extending outward. Of course, when the second photovoltaic panel 12 slides in the guide rail 22 , the first groove wall 311 and the second groove wall 312 of the sliding groove 31 can respectively provide sliding support for the first portion 131 and the second portion 132 of the first frame 122 .

[0068] Exemplarily, there may be two reinforcing plates 30, the notches of the slide slots 31 of the two reinforcing plates 30 are arranged opposite to each other, the two first frames 122 correspond to the two slide slots 31 one by one, and each first frame 122 is slidably assembled in the corresponding slide slot 31. The first part 131 of each first frame 122 presses against the first slot wall 311 of the slide slot 31, and the second slot wall 312 of each slide slot 31 presses against the second part 132 of the first frame 122. Thus, the first slot wall 311 of the slide slot 31 in the reinforcing plate 30 supports the first frame 122 of the second photovoltaic panel 12, and the second slot wall 312 of the slide slot 31 in the reinforcing plate 30 presses against the first frame 122 of the second photovoltaic panel 12, so as to prevent the extended part of the second photovoltaic panel 12 from sagging excessively.

[0069] Exemplary, reference Figure 6 , Figure 7 and Figure 8, the first part 131 of the first frame 122 is connected with a first connecting plate 123 forming a first preset angle 71 with the first part 131, and the first groove wall 311 of the slide groove 31 is connected with a third connecting plate 321 forming a second preset angle 81 with the first groove wall 311. The first preset angle 71 and the second preset angle 81 are consistent, that is, the values ​​of the first preset angle 71 and the second preset angle 81 are equal or differ within a preset range, and the preset range can be 5°, 10°, etc. Exemplarily, the values ​​of the first preset angle 71 and the second preset angle 81 can be any preset angle such as 75°, 80°, 90°, 100°, 105°, etc. And at least part of the third connecting plate 321 is opposite to the first connecting plate 123 to limit the first connecting plate 123. The reinforcing plate 30 can withstand a larger cantilever support force, and the stability of the second photovoltaic panel 12 is also improved.

[0070] Exemplary, reference Figure 6 , Figure 7 and Figure 8 , the first portion 131 of the first frame 122 of the second photovoltaic panel 12 may be connected to the first connecting plate 123, and the first connecting plate 123 is parallel to the first direction, that is, the first preset angle 71 is 90°. Figure 6 and Figure 7 , the first connecting plate 123 can be bent downward from the first part 131 of the first frame 122, that is, the first connecting plate 123 protrudes from the first part 131 of the first frame 122. That is, the first connecting plate 123 is arranged vertically with the second photovoltaic panel 12, and can better disperse and transmit force when the second photovoltaic panel 12 bears its own gravity, thereby effectively improving the bending resistance of the first frame 122 and the bending strength of the second photovoltaic panel 12 in the first direction, so that when the second photovoltaic panel 12 extends outward, the gravity of the extended part of the second photovoltaic panel 12 can be transmitted to the slide groove 31 of the reinforcing plate 30 through the first frame 122 and the first connecting plate 123, and the first groove wall 311 of the slide groove 31 supports the first part 131 of the first frame 122, and the second groove wall 312 of the slide groove 31 presses the second part 132 of the first frame 122, so as to prevent the extended part of the second photovoltaic panel 12 from excessively sagging, thereby improving the support stability of the extended second photovoltaic panel 12.

[0071] Exemplary, reference Figure 6 , Figure 7 and Figure 8, the first groove wall 311 of the slide groove 31 is connected to a third connecting plate 321 parallel to the first direction, that is, the second preset angle 81 is also 90° equal to the first preset angle 71. And at least part of the third connecting plate 321 is opposite to the first connecting plate 123 to limit the first connecting plate 123 in the second direction. Among them, the second direction is perpendicular to the extension direction of the slide groove 31 and the first direction. That is, the second direction is the left and right direction of the second photovoltaic panel 12. Exemplarily, refer to Figure 6 and Figure 7 , the third connecting plate 321 can be bent downward from the first groove wall 311. When the second photovoltaic panel 12 shakes in the slide groove 31 along the second direction, after the first connecting plate 123 on the first frame 122 presses against the third connecting plate 321, the third connecting plate 321 can prevent the first connecting plate 123 from further shaking in the second direction, so that the second photovoltaic panel 12 can slide smoothly in the guide rail 22 and the slide groove 31. And when the first connecting plate 123 of the first frame 122 undergoes a large deformation along the second direction, the first connecting plate 123 can be pressed against the third connecting plate 321, and the third connecting plate 321 prevents the first connecting plate 123 from further deformation, so that the reinforcing plate 30 can withstand a larger cantilever support force, and also improve the stability of the second photovoltaic panel 12.

[0072] Exemplary, reference Figure 6 , Figure 7 and Figure 8 , the first connecting plate 123 is connected to the second connecting plate 124 forming a third preset angle 72 with the first connecting plate 123, and the third connecting plate 321 is connected to the fourth connecting plate 322 forming a fourth preset angle 82 with the third connecting plate 321. The third preset angle 72 is consistent with the fourth preset angle 82. The third preset angle 72 is consistent with the fourth preset angle 82, that is, the values ​​of the third preset angle 72 and the fourth preset angle 82 are equal or differ within a preset range, and the preset range can be 5°, 10°, etc. Exemplarily, the values ​​of the third preset angle 72 and the fourth preset angle 82 can be any preset angle such as 75°, 80°, 90°, 100°, 105°, etc., and the second connecting plate 124 is opposite to the fourth connecting plate 322, so that the second connecting plate 124 can press the fourth connecting plate 322. The gravity of the extended part of the second photovoltaic panel 12 is dispersed and transmitted to the housing 23 through a larger force transmission area, so that the reinforcing plate 30 can withstand a larger cantilever support force.

[0073] Exemplary, reference Figure 6 , Figure 7 and Figure 8, the first connecting plate 123 is connected to the second connecting plate 124 which is perpendicular to the first direction, and the third preset angle 72 is 90°. The third connecting plate 321 is connected to the fourth connecting plate 322 which is perpendicular to the first direction, and the fourth preset angle 82 is 90°. That is, the first connecting plate 123 is connected to the second connecting plate 124, and the second connecting plate 124 is perpendicular to the first direction, that is, the second connecting plate 124 is arranged parallel to the second photovoltaic panel 12. The third connecting plate 321 is connected to the fourth connecting plate 322, and the fourth connecting plate 322 is also perpendicular to the first direction. Exemplarily, the bending direction of the second connecting plate 124 relative to the first connecting plate 123 is the direction away from the groove wall of the chute 31, that is, the second connecting plate 124 is bent relative to the first connecting plate 123 in the direction away from the chute 31. At least part of the second connecting plate 124 is opposite to the fourth connecting plate 322, so that the second connecting plate 124 can be pressed against the fourth connecting plate 322. When the second connecting plate 124 of the first frame 122 is greatly deformed, it abuts against the fourth connecting plate 322, and the fourth connecting plate 322 can support the second connecting plate 124, and the fourth connecting plate 322 prevents the third connecting plate 321 from further deforming. When the second photovoltaic panel 12 partially extends outward, the gravity of the extended part can be transmitted to the non-extended part of the first frame 122 through the first frame 122, the first connecting plate 123 on the first frame 122, and the third connecting plate 321 in sequence. Afterwards, the non-extending portion of the first frame 122 can transmit the force to the shell 23 through the groove wall of the slide groove 31, the second connecting plate 124 and the fourth connecting plate 322, thereby increasing the force transmission area of ​​the support member and the second photovoltaic panel 12 during the cantilever support in the first direction, so that the gravity of the extended portion of the second photovoltaic panel 12 is dispersedly transmitted to the shell 23 through a larger force transmission area, so that the reinforcing plate 30 can withstand a larger cantilever support force, thereby improving the supporting stability of the reinforcing plate 30 to the first frame 122, and improving the reliable stability of the cantilever support of the second photovoltaic panel 12.

[0074] Exemplary, reference Figure 6 , Figure 7 and Figure 8, the second part 132 of the first frame 122 is connected with a fifth connecting plate 125 that forms a sixth preset angle 73 with the second part 132, and the second groove wall 312 of the slide groove 31 is connected with a seventh connecting plate 323 that forms a seventh preset angle 84 with the second groove wall 312. The sixth preset angle 73 is consistent with the seventh preset angle 84. That is, the values ​​of the sixth preset angle 73 and the seventh preset angle 84 are equal or differ within a preset range, and the preset range can be 5°, 10°, etc. Exemplarily, the values ​​of the sixth preset angle 73 and the seventh preset angle 84 can be any preset angle such as 75°, 80°, 90°, 100°, 105°, etc. And at least part of the seventh connecting plate 323 is opposite to the fifth connecting plate 125 to limit the fifth connecting plate 125. The reinforcing plate 30 can withstand a larger cantilever support force, and the stability of the second photovoltaic panel 12 is also improved.

[0075] In a more preferred embodiment, reference Figure 6 , Figure 7 and Figure 8 , a fifth connecting plate 125 is connected to the second portion of the first frame 122 of the second photovoltaic panel 12, and the fifth connecting plate 125 is parallel to the first direction, that is, the sixth preset angle 73 is also 90°. That is, the fifth connecting plate 125 is arranged perpendicular to the second photovoltaic panel 12. For example, refer to Figure 6 and Figure 7 , the fifth connecting plate 125 can be bent upward from the second part 132 of the first frame 122, that is, the fifth connecting plate 125 protrudes from the second part 132 of the first frame 122. When the second photovoltaic panel 12 bears its own gravity, it can better disperse and transmit force, thereby effectively improving the bending resistance of the first frame 122 and the bending strength of the second photovoltaic panel 12 in the first direction. When the second photovoltaic panel 12 extends outward, the gravity of the extended part of the second photovoltaic panel 12 can be transmitted to the slide groove 31 of the reinforcing plate 30 through the first frame 122 and the fifth connecting plate 125, and the first groove wall 311 of the slide groove 31 supports the first part 131 of the first frame 122, and the second groove wall 312 of the slide groove 31 presses the second part 132 of the first frame 122, so as to prevent the extended part of the second photovoltaic panel 12 from excessively sagging, thereby improving the support stability of the extended second photovoltaic panel 12.

[0076] Exemplary, reference Figure 6 , Figure 7 and Figure 8, the second groove wall 312 of the slide groove 31 is connected to the seventh connecting plate 323 parallel to the first direction, that is, the seventh preset angle 84 is also 90°. At least part of the seventh connecting plate 323 is opposite to the fifth connecting plate 125 to limit the fifth connecting plate 125 in the second direction. The second direction is perpendicular to the extension direction of the slide groove 31 and the first direction, that is, the second direction is the left and right direction of the second photovoltaic panel 12. For example, refer to Figure 6 and Figure 7 , the seventh connecting plate 323 can be bent upward from the second groove wall 312 of the slide groove 31. When the second photovoltaic panel 12 shakes in the slide groove 31 along the second direction, after the fifth connecting plate 125 on the first frame 122 presses against the seventh connecting plate 323, the seventh connecting plate 323 can prevent the fifth connecting plate 125 from further shaking in the second direction, so that the second photovoltaic panel 12 can slide smoothly in the guide rail 22 and the slide groove 31. And when the fifth connecting plate 125 of the first frame 122 undergoes a large deformation along the second direction, the fifth connecting plate 125 can be pressed against the seventh connecting plate 323, and the seventh connecting plate 323 prevents the fifth connecting plate 125 from further deformation, so that the reinforcing plate 30 can withstand a larger cantilever support force, and also improve the stability of the second photovoltaic panel 12.

[0077] Exemplary, reference Figure 6 , Figure 7 and Figure 8 , the fifth connecting plate 125 is connected to the sixth connecting plate 126 forming the eighth preset angle 74 with the fifth connecting plate 125, and the seventh connecting plate 323 is connected to the eighth connecting plate 324 forming the ninth preset angle 85 with the seventh connecting plate 323. The eighth preset angle 74 is consistent with the ninth preset angle 85. The eighth preset angle 74 is consistent with the ninth preset angle 85, that is, the values ​​of the eighth preset angle 74 and the ninth preset angle 85 are equal or differ within a preset range, and the preset range can be 5°, 10°, etc. Exemplarily, the values ​​of the eighth preset angle 74 and the ninth preset angle 85 can be any preset angle such as 75°, 80°, 90°, 100°, 105°, etc. And at least part of the sixth connecting plate 126 is opposite to the eighth connecting plate 324, so that the eighth connecting plate 324 can press the sixth connecting plate 126. The gravity of the extended part of the second photovoltaic panel 12 is dispersed and transmitted to the housing 23 through a larger force transmission area, so that the reinforcing plate 30 can withstand a larger cantilever support force.

[0078] Exemplary, reference Figure 6 , Figure 7 and Figure 8, the fifth connecting plate 125 is connected to the sixth connecting plate 126 perpendicular to the first direction, and the eighth preset angle 74 is 90°. The seventh connecting plate 323 is connected to the eighth connecting plate 324 perpendicular to the first direction, and the ninth preset angle 85 is 90°. That is, the sixth connecting plate 126 is connected to the fifth connecting plate 125, and the sixth connecting plate 126 is perpendicular to the first direction, and the sixth connecting plate 126 is arranged parallel to the second photovoltaic panel 12. The eighth connecting plate 324 is connected to the seventh connecting plate 323, and the eighth connecting plate 324 is also perpendicular to the first direction, and the eighth connecting plate 324 is also arranged parallel to the second photovoltaic panel 12. At least part of the eighth connecting plate 324 is opposite to the eighth connecting plate 324, so that the eighth connecting plate 324 can be pressed against the sixth connecting plate 126. Exemplarily, the bending direction of the sixth connecting plate 126 relative to the fifth connecting plate 125 is the direction away from the groove wall of the slide groove 31, that is, the sixth connecting plate 126 is bent relative to the fifth connecting plate 125 in the direction away from the slide groove 31. At least part of the sixth connecting plate 126 is opposite to the eighth connecting plate 324, so that the eighth connecting plate 324 can press against the sixth connecting plate 126. When the sixth connecting plate 126 of the first frame 122 is greatly deformed, it is pressed against the eighth connecting plate 324, and the eighth connecting plate 324 can press against the sixth connecting plate 126 to prevent the sixth connecting plate 126 from further deformation. And when the second photovoltaic panel 12 partially extends outward, the gravity of the extended part can be transmitted to the non-extended part of the first frame 122 through the first frame 122, the fifth connecting plate 125 on the first frame 122, and the seventh connecting plate 323 in sequence. Afterwards, the non-extending portion of the first frame 122 can transmit the force to the shell 23 through the groove wall of the slide groove 31, the sixth connecting plate 126 and the eighth connecting plate 324, thereby increasing the force transmission area of ​​the support member and the second photovoltaic panel 12 during the cantilever support in the first direction, so that the gravity of the extended portion of the second photovoltaic panel 12 is dispersedly transmitted to the shell 23 through a larger force transmission area, so that the reinforcing plate 30 can withstand a larger cantilever support force, thereby improving the supporting stability of the reinforcing plate 30 to the first frame 122, and improving the reliable stability of the cantilever support of the second photovoltaic panel 12.

[0079] In some embodiments, reference Figure 6 , Figure 7 and Figure 8 , the first connecting plate 123, the second connecting plate 124, the fifth connecting plate 125 and the sixth connecting plate 126 can be arranged on the first frame 122 of the second photovoltaic panel 12. Correspondingly, the third connecting plate 321, the fourth connecting plate 322, the seventh connecting plate 323 and the eighth connecting plate 324 are arranged on each reinforcing plate 30. This further improves the strength of the second photovoltaic panel 12 and the reinforcing plate 30, thereby improving the support reliability of the second photovoltaic panel 12 when it is extended.

[0080] Exemplary, reference Figure 6 , Figure 7 and Figure 8 When fixing the reinforcing plate 30, a first mounting plate 325 may be further provided on the fourth connecting plate 322 of the reinforcing plate 30, the first mounting plate 325 and the fourth connecting plate 322 form a fifth preset angle 83, and the first mounting plate 325 is fixedly connected to the housing 23. Exemplarily, the fifth preset angle 83 may be any preset angle such as 75°, 80°, 90°, 100°, 105°, etc. Exemplarily, referring to Figure 6 , Figure 7 and Figure 8 , the first mounting plate 325 is parallel to the first direction, that is, the fifth preset angle 83 is 90°, and the first mounting plate 325 is fixedly connected to the housing 23. The specific fixing method can be bolted or screwed. In this way, it is not only convenient to fix the reinforcing plate 30 on the housing 23, but also the reinforcing plate 30 is placed vertically to improve the bending strength of the reinforcing plate 30, so that the reinforcing plate 30 can withstand a larger cantilever support force, thereby further improving the support stability of the second photovoltaic panel 12.

[0081] Exemplarily, a second mounting plate 326 is disposed on the eighth connecting plate 324 of the reinforcing plate 30, the second mounting plate 326 and the eighth connecting plate 324 form a tenth preset angle 86, and the second mounting plate 326 is fixedly connected to the housing 23. Exemplarily, the tenth preset angle 86 can be any preset angle such as 75°, 80°, 90°, 100°, 105°, etc. Exemplarily, refer to Figure 6 , Figure 7 and Figure 8 , the second mounting plate 326 is parallel to the first direction, that is, the tenth preset angle 86 is 90°, and the second mounting plate 326 is fixedly connected to the housing 23. The reinforcing plate 30 is fixed to the housing 23 by the second mounting plate 326. The specific fixing method can be fastened by bolts or screws. In this way, it is not only convenient to fix the reinforcing plate 30 on the housing 23, but also the reinforcing plate 30 is placed vertically to improve the bending strength of the reinforcing plate 30, so that the reinforcing plate 30 can withstand a larger cantilever support force, thereby further improving the support stability of the second photovoltaic panel 12.

[0082] In the above-mentioned method, reference is made to Figure 6 , Figure 7 and Figure 8, the cross-sectional structure of the reinforcing plate 30 and the first frame 122 of the second photovoltaic panel 12 is set as a secondary superposition reinforcement structure similar to a "double C shape" as a support member to achieve an increase in the reinforcement support between the reinforcing plate 30 and the first frame 122 of the second photovoltaic panel 12. In addition, it should be noted that the method of supporting and reinforcing the reinforcing plate 30 and the first frame 122 of the second photovoltaic panel 12 is not limited to the method shown above. In addition, other methods can also be adopted. For example, the cross-sectional structure of the reinforcing plate 30 and the first frame 122 of the second photovoltaic panel 12 is set as a secondary superposition reinforcement structure similar to a "double U shape", or a "double V shape", or a "double semi-circle superposition" as a support member, which can also achieve an increase in the high bending strength in the horizontal and vertical directions, but it is more difficult to manufacture and form the parts, and the assembly accuracy requirements will be higher.

[0083] When determining the material of the reinforcing plate 30, any metal material such as but not limited to aluminum alloy, carbon steel (exemplarily, low-carbon steel SAPH400 can be selected), stainless steel, etc. can be used to improve the strength of the reinforcing plate 30. Of course, the materials of the guide rail 22, the support beam 21, and the support structure can also be selected from any metal materials such as but not limited to aluminum alloy, carbon steel, stainless steel, etc. to improve the strength.

[0084] In some embodiments, referring to Figure 6 , Figure 7 and Figure 8 , at least one noise reduction member 33 can be provided in the chute 31. At least part of the noise reduction member 33 is placed on the inner wall of the chute 31, that is, all the noise reduction members 33 can be located on the inner wall of the chute 31, or part of the noise reduction members 33 can be located on the inner wall of the chute 31. When the second photovoltaic panel 12 is located in the chute 31, the noise reduction member 33 is used to press against the second photovoltaic panel 12, so that the second photovoltaic panel 12 is in sliding contact with the chute 31 through the noise reduction member 33, reducing the noise when the second photovoltaic panel 12 slides in the chute 31, and realizing the silent sliding of the second photovoltaic panel 12. Exemplarily, the material of the noise reduction member 33 can be a noise-reducing material such as but not limited to engineering plastics.

[0085] Exemplarily, referring to Figure 6 , Figure 7 and Figure 8, at least one noise reduction member 33 can be arranged in the sliding groove 31. The material of the noise reduction member 33 can be engineering plastic. The first frame 122 and the sliding groove 31 are separated by the noise reduction member 33. By using the sliding silent and wear-resistant characteristics of engineering plastic, the first frame 122 slides in the sliding groove 31 in an almost silent manner. Obviously, the noise reduction member 33 is a convex structure formed in the sliding groove 31 with engineering plastic as the raw material. Engineering plastic can adopt materials such as but not limited to polyoxymethylene (POM), polyamide, polyphenylene sulfide, polycarbonate, etc. The number of noise reduction members 33 in each sliding groove 31 can be two, three, four or more. The shape of each noise reduction member 33 is a structure similar to a "匚" shape and is installed in the sliding groove 31.

[0086] Exemplarily, referring to Figure 7 and Figure 8 , a limiting structure 40 can also be arranged at the notch of the sliding groove 31 of the reinforcing plate 30. The limiting structure 40 is used to limit the first frame 122 in the sliding groove 31. Exemplarily, when the number of reinforcing plates 30 is two and each reinforcing plate 30 corresponds to a guide rail 22 and is arranged at the entrance of the corresponding guide rail 22, the number of limiting structures 40 is also two, and each limiting structure 40 corresponds to a reinforcing plate 30 and is arranged at the notch of the corresponding sliding groove 31. Thus, the two first frames 122 on the left and right sides of the second photovoltaic panel 12 (the left and right sides are in the second direction, and the second direction is perpendicular to the first direction and the extending direction of the sliding groove 31) are respectively limited in their respective sliding grooves 31 by the two limiting structures 40 on the left and right sides, preventing each first frame 122 from disengaging from the notch of its respective sliding groove 31. Even when the second photovoltaic panel 12 is blown by strong wind and the first frame 122 is deformed, the limiting structure 40 can still limit its respective first frame 122 in its respective sliding groove 31, so that the first frame 122 will not disengage from the sliding groove 31 and cause the second photovoltaic panel 12 to fall apart.

[0087] When arranging the limiting structure 40, various methods can be adopted. Referring to Figure 7 and Figure 8Exemplarily, the limiting structure 40 may have a first limiting end face 41, and the limiting end face 41 abuts against the second limiting end face 133 of the first part 131 and / or the second part of the first frame 122. It should be explained that the second limiting end face 133 of the first part 131 and / or the second part 132 of the first frame 122 refers to the edge end face of the first part 131 and / or the second part 132 of the first frame 122 facing the power generation area of ​​the second photovoltaic panel 12. Exemplarily, the number of the first limiting end faces 41 on the limiting structure 40 is two, and the two first limiting end faces 41 abut against the second limiting end faces 133 of the first part 131 and the second part 132 of the first frame 122, respectively. At this time, the limiting structure 40 can adopt a hook mechanism, and the number of the limiting structures 40 can be two, each of which has a first limiting end face 41, one of which is located above the second photovoltaic panel 12, and the first limiting end face 41 of the limiting structure 40 abuts against the second limiting end face 133 of the second part 132 of the first frame 122 of the second photovoltaic panel 12; the other limiting structure 40 is located below the second photovoltaic assembly, and the first limiting end face 41 of the limiting structure 40 abuts against the second limiting end face 133 of the first part 131 of the second frame of the second photovoltaic panel 12. In this way, the first frame 122 of the second photovoltaic panel 12 is limited to move left and right, and the first frame 122 is prevented from slipping out of the slide groove 31, simplifying the structure of the limiting structure 40. Of course, in some embodiments, the number of the limiting structure 40 can be one. The number of the first limiting end surface 41 may be one, and the first limiting end surface 41 abuts against the first portion 131 of the first frame 122 or the second limiting end surface 133 of the second portion 132 of the first frame 122 .

[0088] Exemplary, reference Figure 7 and Figure 8 When fixing the limiting structure 40, the limiting structure 40 and the reinforcing plate 30 can be fixed to the housing 23 together. The specific fixing method can be bolted or screwed. Exemplarily, the reinforcing plate 30 and the limiting structure 40 are fixed to the housing 23 by self-tapping screws, eliminating the horizontal and vertical movement gap between the first frame 122 of the second photovoltaic panel 12 and the slide groove 31 when the first frame 122 of the second photovoltaic panel 12 slides in the slide groove 31.

[0089] Exemplary, reference Figure 1 to Figure 4, the shell 23 may also include: a protective shell 50, an opening 51 is provided at the entrance of the protective shell guide rail 22, and the second photovoltaic panel 12 extends outward through the opening 51. And the second photovoltaic panel 12 also has a second side, and a cover plate 52 is provided on the second side. Exemplarily, a second frame may be provided on the second side, and the cover plate 52 is provided on the second frame. When the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11, the cover plate 52 is buckled at the opening 51. Among them, the second side beam may be a side connecting the two first side edges 121. By providing a protective shell 50, an opening 51 for the second photovoltaic panel 12 to extend or retract is provided on the protective shell 50, and a cover plate 52 is provided on the second side of the second photovoltaic panel 12. When the second photovoltaic panel 12 is retracted to the bottom of the first photovoltaic panel 11, the cover plate 52 on the second side can be tightly buckled at the opening 51 of the protective shell 50, and the second photovoltaic panel 12 and battery packs and other devices can be protected.

[0090] In some embodiments, reference Figure 2 and Figure 3 , the photovoltaic panel structure may also include: a motor 61 disposed on the shell 23, and a transmission mechanism 62 connected between the second photovoltaic panel 12 and the output shaft of the motor 61, the motor 61 is used to drive the second photovoltaic panel 12 to slide in the guide rail 22 through the transmission mechanism 62. Exemplarily, the motor 61 may be disposed on the shell 23, and the transmission mechanism 62 may be disposed between the output shaft of the motor 61 and the two first side edges 121 of the second photovoltaic panel 12. When the output shaft of the motor 61 rotates, the two first side edges 121 of the second photovoltaic panel 12 may be driven to slide in the two guide rails 22 respectively through the transmission mechanism 62, thereby realizing the automatic extension or automatic retraction of the second photovoltaic panel 12, and improving the degree of automation of the photovoltaic panel assembly. When setting the transmission mechanism 62, a variety of types of transmission mechanisms 62 may be used. Exemplarily, transmission methods such as but not limited to flexible shafts, magnetic strips, etc. may be used. Figure 3 It is a schematic diagram of the second photovoltaic panel 12 extending outward, the thin dotted line is a hidden diagram of the transmission mechanism 62 and the motor 61 when the second photovoltaic panel 12 is in the extended outward state, and the double-dotted line is the transmission flexible shaft assembly in the transmission mechanism 62.

[0091] like Figure 4 , is a rear view of the reinforcing plate 30 and the limiting structure 40 being fixed to the inner side of the guide rail 22 by screws, and the dotted line is the outline of the reinforcing plate 30 and the limiting structure 40.

The dotted line is the cross-sectional profile of the reinforcing plate 30 and the limiting structure 40. The inner slide groove 31 wraps the first frame 122 of the second photovoltaic panel 12. Figure 6In [the figure], it is a three-dimensional side view of the reinforcement plate 30. The protrusion 33 provided in the chute 31 is coated with the main base material of the reinforcement plate 30, and the main base material can be low-carbon steel (SAPH400). As Figure 7 In [the figure], it is a partial cross-sectional view when the second photovoltaic panel 12 is assembled together with the left guide rail 22, the reinforcement plate 30, and the limiting structure 40. As Fig. 9 In [the figure], it is a front left view of the photovoltaic panel assembly after being assembled on the vehicle body. The thin dotted line is the hidden position of the reinforcement plate 30 arranged in the guide rail 22. The second photovoltaic panel 12 is in the extended state, and at this time, the photovoltaic panel system is in the power charging mode.

[0092] Exemplarily, when the second photovoltaic panel 12 extends, the main supporting force is concentrated on the reinforcement plate 30, and the reaction force is mainly concentrated at a position about 260 mm from the rear end of the first frame 122 of the second photovoltaic panel 12. See Figure 5 、 Figure 7 、 Figure 8 And Fig. 9 . The cross-sectional structure of the reinforcement plate 30 and the first frame 122 of the second photovoltaic panel 12 is provided with a secondary superimposed reinforcement structure similar to a "double C-shaped", "double U-shaped", or "double V-shaped" as one of the support members of the support member. As Figure 7 , it improves the lateral and longitudinal bending resistance of the second photovoltaic panel 12 when it extends. The contact method of the protrusion 33 provided in the chute 31 of the reinforcement plate 30 realizes linear contact, eliminates the longitudinal jumping gap, and can also avoid abnormal noises generated during the movement of the second photovoltaic panel 12 and the driving of the vehicle on which the photovoltaic panel system is assembled. Figure 2 And Figure 3 The double-dotted lines in [the figures] are the operating trajectories of the motor 61 and the transmission mechanism 62 driving the first frame 122 of the second photovoltaic panel 12. The power can be transmitted to the transmission mechanism 62 by driving the motor 61 through the control module (PLC), so as to realize the movement of the second photovoltaic panel 12 and switch between the two states of one-key extension and retraction of the second photovoltaic panel 12.

[0093] In some of the embodiments shown above, not only the first photovoltaic panel 11 is fixedly arranged, but also the second photovoltaic panel 12 is additionally arranged, and the two opposite first side edges 121 of the second photovoltaic panel 12 are respectively slidably assembled in the two guide rails 22. When in use, the second photovoltaic panel 12 can be retracted to the bottom of the first photovoltaic panel 11, or the second photovoltaic panel 12 can be extended from the bottom of the first photovoltaic panel 11, so that the photovoltaic panel assembly has two different solar power generation powers. When the second photovoltaic panel 12 is extended, the second photovoltaic panel 12 is a cantilever beam support, and there is no force point directly above and directly below the extended part of the second photovoltaic panel 12. Generally, the cantilever support has high requirements on the bending strength of the structural parts. In this application, a support member is arranged in each guide rail 22. When part of the second photovoltaic panel 12 extends out of the two guide rails 22, the support member cantilever supports the second photovoltaic assembly to improve the support stability of the second photovoltaic panel 12.

[0094] Furthermore, the present application embodiment also provides a photovoltaic panel assembly, referring to Figures 1 to 8 , the photovoltaic panel assembly includes: a battery pack, and any one of the above-mentioned photovoltaic panel structures, the battery pack is arranged on the shell 23 and is electrically connected to the first photovoltaic panel 11 and / or the second photovoltaic panel 12. Exemplarily, the battery pack can be opposite to the first photovoltaic panel 11 and / or the second photovoltaic panel 12. Exemplarily, the battery pack can be located below the second photovoltaic panel 12. Exemplarily, when the second photovoltaic panel 12 is shielded by the first photovoltaic panel 11, the battery pack can be opposite to the second photovoltaic panel 12. When the second photovoltaic panel 12 extends outward, the battery pack can be opposite to the first photovoltaic panel 11. Thus, from bottom to top, a stacked battery pack, a slidingly assembled second photovoltaic panel 12, and a fixedly assembled first photovoltaic panel 11 are formed in sequence, thereby improving the assembly density of the photovoltaic panel assembly and reducing the space occupied by the photovoltaic panel assembly.

[0095] Exemplarily, the photovoltaic panel assembly may also include a charging device, which is electrically connected to the battery pack and is used to charge the vehicle. That is, the charging device is connected between the battery pack and the vehicle, so that the vehicle can be charged through the battery pack. The charging device may include a charging gun, which is plug-connected to the vehicle to facilitate pluggable connection with the vehicle.

[0096] Exemplary, reference Figure 2 and Figure 3 The photovoltaic panel assembly may also include an inverter connected between the battery pack and the two photovoltaic panels, so that the power generated by the photovoltaic panels when irradiated by sunlight can be adjusted to charge the battery pack. Exemplarily, the inverter can be set in the height space occupied by the battery pack and the second photovoltaic panel 12, thereby improving the assembly density.

[0097] Exemplarily, in a photovoltaic panel assembly, reference Figure 2 and Figure 3 , may include a first photovoltaic panel 11 on the top layer, a second photovoltaic panel 12 on the middle layer, and an energy storage battery pack on the bottom layer. An inverter and a controller may be provided on one side of the battery pack. When the second photovoltaic panel 12 is extended, the photovoltaic panel assembly is in a high-power power generation mode, and the charging power of the high-power power generation mode can be 520W, which can well increase the charging power of the photovoltaic panel assembly. When the second photovoltaic panel 12 is retracted, the photovoltaic panel assembly is in a low-power power generation mode, and the charging power of the low-power power generation mode can be 320W. Exemplarily, when the second photovoltaic panel 12 is extended, the second photovoltaic panel 12 is connected in parallel with the first photovoltaic panel 11, and the photovoltaic panel assembly is in a high-power power generation mode. When the second photovoltaic panel 12 is retracted, the power generation power of the second photovoltaic panel 12 is 0, and the photovoltaic panel system switches to a low-power power generation mode.

[0098] Exemplary, reference Figure 2 and Figure 3 The photovoltaic panel assembly may further include a controller, which may be disposed within the height space occupied by the battery pack and the second photovoltaic panel 12, thereby improving the assembly density.

[0099] In addition, the present application embodiment also provides a vehicle, referring to Fig. 9 The vehicle includes: any one of the above photovoltaic panel structures or any one of the above photovoltaic panel assemblies. Exemplarily, the photovoltaic panel assembly can be connected to the top of the vehicle body. Specifically, the housing 23 in the photovoltaic panel assembly can be set on the sheet metal on the top of the vehicle body. The vehicle can be, for example, but not limited to, an electric vehicle, a hybrid vehicle, a fuel vehicle, etc.
