[0039] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described to avoid confusion with the present application embodiments.

[0042] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0043] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.

[0044] As shown in Figures 1 to 7, an embodiment of the present application provides a solar power generation device 1, which includes a first photovoltaic panel 10 and a second photovoltaic panel 20. The second photovoltaic panel 20 is located above the first photovoltaic panel 10. The second photovoltaic panel 20 can move relative to the first photovoltaic panel 10. For example, the second photovoltaic panel 20 has a first position, a second position and a third position relative to the first photovoltaic panel 10. When the second photovoltaic panel 20 is in the first position (see Figure 6), the second photovoltaic panel 20 is staggered with the first photovoltaic panel 10 to maximize exposure to the first photovoltaic panel 10. When the second photovoltaic panel 20 is in the second position (see Figure 2), the second photovoltaic panel 20 is generally located directly above the first photovoltaic panel 10 and is spaced apart from the first photovoltaic panel 10. When the second photovoltaic panel 20 is in the third position (see Figure 1), the second photovoltaic panel 20 is generally located directly above the first photovoltaic panel 10 and is in contact with the first photovoltaic panel 10.

[0045] The solar power generation device 1 drives the second photovoltaic panel 20 specifically through the following structure.

[0046] The solar power generation device 1 includes a slide rail 11 , a slide rod 21 and a connecting rod 22 .

[0047] The slide rail 11 is provided on the first photovoltaic panel 10 and is parallel to the first photovoltaic panel 10. The first photovoltaic panel 10 has at least one slide rail 11. The slide rail 11 extends along the first direction D1. The first direction D1 corresponds to a horizontal direction, for example. The first direction D1 corresponds to the front and rear direction of the vehicle, for example. Optionally, the slide rail 11 is fixedly connected to the side (left and / or right) of the first photovoltaic panel 10 and is parallel to the moving direction of the second photovoltaic panel 20. It can be understood that the number of slide rails 11 can be two, and the two slide rails 11 are provided on both sides of the first photovoltaic panel 10 along the second direction D2. The slide rail 11 is used to provide parallel tracks to achieve stable operation. The second direction D2 is different from the first direction D1, for example, the second direction D2 is perpendicular to the first direction D1. The second direction corresponds to a horizontal direction, for example. The second direction D2 corresponds to the left and right direction of the vehicle, for example.

[0048] In this application, the front-to-back direction refers to the front-to-back direction of the vehicle when the vehicle is fully assembled, wherein the front of the vehicle is the front and the rear of the vehicle is the rear; the left-to-right direction is also the width direction of the vehicle. When the user faces the front of the vehicle in the vehicle, the side corresponding to the user's left side is the left side, and the side corresponding to the user's right side is the right side.

[0049] The slide bar 21 is disposed corresponding to the slide rail 11. The slide bar 21 is disposed below the second photovoltaic panel 20 and is slidably connected to the corresponding slide rail 11. The slide bar 21 is slidably connected to the slide rail 11 along a first direction D1. As will be appreciated, as the slide bar 21 moves away from the first photovoltaic panel 10, it gradually extends out of the slide rail 11. As the slide bar 21 moves toward the first photovoltaic panel 10, it gradually retracts into the slide rail 11.

[0050] The second photovoltaic panel 20 is connected to the slide bar 21 and can move relative to the first photovoltaic panel 10 in a first direction D1 as the slide bar 21 slides, thereby shielding or exposing the first photovoltaic panel 10. When the slide bar 21 moves away from the first photovoltaic panel 10, the second photovoltaic panel 20 moves with the slide bar 21 to the side of the first photovoltaic panel 10, thereby exposing the first photovoltaic panel 10 to varying degrees. As shown in Figure 6, when the slide bar 21 is extended to its extreme position, the second photovoltaic panel 20 is in the first position, which is also the extreme position of the second photovoltaic panel 20 away from the first photovoltaic panel 10 in the first direction D1. At this point, the entire area of ​​the second photovoltaic panel 20 is exposed to sunlight and can generate electricity. The entire area of ​​the first photovoltaic panel 10 is exposed to sunlight and can generate electricity. The full area of ​​the first photovoltaic panel 10 is capable of generating electricity when the solar cells of the first photovoltaic panel 10 are fully exposed to sunlight, without any other structures blocking the sunlight, and the solar cells convert the sunlight energy into electricity. The full area of ​​the second photovoltaic panel 20 can generate electricity means that in the absence of any other structures blocking it, the solar cells of the second photovoltaic panel 20 can all be illuminated by sunlight, and the solar cells convert light energy into electrical energy.

[0051] When the second photovoltaic panel 20 is in the first position, the second photovoltaic panel 20 does not block the first photovoltaic panel 10. In other words, when the second photovoltaic panel 20 moves along the first direction D1 to the extreme position away from the first photovoltaic panel 10, in the projection of the solar power generation device 1 along the direction perpendicular to the first photovoltaic panel 10, the first photovoltaic panel 10 and the second photovoltaic panel 20 do not overlap.

[0052] It can be understood that there are two sliding rods 21 , and the two sliding rods 21 are adapted to the two sliding rails 11 .

[0053] The connecting rod 22 connects the second photovoltaic panel 20 to the sliding rod 21 below it, maintaining a certain distance between the second photovoltaic panel 20 and the sliding rod 21, and thereby maintaining a certain distance between the second photovoltaic panel 20 and the first photovoltaic panel 10. One end 221 of the connecting rod 22 is rotatably connected to the sliding rod 21, and the other end 222 of the connecting rod 22 is rotatably connected to the second photovoltaic panel 20. Thus, the connecting rod 22 can at least adjust the distance between the first photovoltaic panel 10 and the second photovoltaic panel 20 by rotating relative to the first photovoltaic panel 10 and the second photovoltaic panel 20.

[0054] As shown in Figure 1, the sliding rod 21 is retracted to the extreme position. When the first photovoltaic panel 10 and the second photovoltaic panel 20 are arranged in parallel, the connecting rod 22 is arranged at an angle, that is, the connecting rod 22 and the first photovoltaic panel 10 (or the connecting rod 22 and the second photovoltaic panel 20) are not parallel and not perpendicular. At this time, the distance between the second photovoltaic panel 20 and the first photovoltaic panel 10 in the vertical direction DH becomes smaller. When the connecting rod 22 is tilted to the extreme angle, the first photovoltaic panel 10 and the second photovoltaic panel 20 are fitted together. At this time, the second photovoltaic panel 20 is in the third position, the entire area of ​​the second photovoltaic panel 20 is illuminated, and the entire area of ​​the second photovoltaic panel 20 can generate electricity. The first photovoltaic panel 10 is in the state of receiving the least light.

[0055] Preferably, the first photovoltaic panel 10 and the second photovoltaic panel 20 are rectangular in shape. The shapes of the first photovoltaic panel 10 and the second photovoltaic panel 20 can also be other shapes. As shown in Figure 2-3, the sliding rod 21 is retracted to the extreme position. When the first photovoltaic panel 10 and the second photovoltaic panel 20 are arranged in parallel, the connecting rod 22 is arranged vertically, that is, the connecting rod 22 is perpendicular to the first photovoltaic panel 10 (or the connecting rod 22 is perpendicular to the second photovoltaic panel 20). At this time, the second photovoltaic panel 20 and the first photovoltaic panel 10 have a certain distance in the vertical direction DH. At this time, the second photovoltaic panel 20 is in the second position, the entire area of ​​the second photovoltaic panel 20 is illuminated, and the entire area of ​​the second photovoltaic panel 20 can generate electricity. A small part of the first photovoltaic panel 10 is illuminated, and a small part of the first photovoltaic panel 10 can generate a small amount of electricity.

[0056] According to the solar power generation device 1 of the present application, the first photovoltaic panel 10 and the second photovoltaic panel 20 are arranged to be relatively movable, thereby reducing the horizontal space occupied. The relative position of the first photovoltaic panel 10 and the second photovoltaic panel 20 can be adjusted according to the actual use space and lighting conditions, thereby changing the area receiving sunlight and improving the efficiency of the photovoltaic panels.

[0057] Optionally, the connecting rod 22 is a telescopic rod. The telescopic rod 22 allows for adjustment of the vertical distance DH between the second photovoltaic panel 20 and the first photovoltaic panel 10, thereby adjusting the amount of light received by the first photovoltaic panel 10. Furthermore, the telescopic rod 22 allows for a loose fit between the second photovoltaic panel 20 and the first photovoltaic panel 10, facilitating movement of the second photovoltaic panel 20.

[0058] Optionally, the connecting rods 22 are divided into two groups, and the two groups of connecting rods 22 are respectively arranged on both sides of the second photovoltaic panel 20 to respectively connect the two sliding rods 21.

[0059] Optionally, the number of each set of connecting rods 22 is one. Two sets of connecting rods 22 are respectively arranged on both sides of the second photovoltaic panel 20. For example, the number of connecting rods 22 is two. The direction of the second photovoltaic panel 20 toward the first position is the front side, and the direction away from the first position is the rear side. The two connecting rods 22 are respectively arranged at the two corners of the front side of the second photovoltaic panel 20, and the two corners of the rear side of the second photovoltaic panel 20 are respectively hingedly connected to the first photovoltaic panel 10. Or the two connecting rods 22 are respectively arranged at the two corners of the rear side of the second photovoltaic panel 20, and the two corners of the front side of the second photovoltaic panel 20 are respectively hingedly connected to the first photovoltaic panel 10.

[0060] Alternatively, optionally, the number of each group of connecting rods 22 is greater than or equal to two. For example, the number of connecting rods 22 is four, with two forming a group, and the four connecting rods 22 are respectively arranged at the four corners of the second photovoltaic panel 20.

[0061] Optionally, the lengths of the same set of connecting rods 22 are different, so that the second photovoltaic panel 20 is tilted relative to the first photovoltaic panel 10, for example, the second photovoltaic panel 20 is rotated relative to the first photovoltaic panel 10 around an axis along the second direction D2. As shown in Figure 4, the sliding rod 21 is retracted to the extreme position. The lengths of the front connecting rod 22 and the rear connecting rod 22 are different, so that when the second photovoltaic panel 20 is in the second position, the second photovoltaic panel 20 is tilted forward and backward relative to the first photovoltaic panel 10. The second photovoltaic panel 20 can be adjusted to an angle facing the sun to ensure stable power generation of the second photovoltaic panel 20, or the amount of shielding of the first photovoltaic panel 10 by the second photovoltaic panel 20 can be changed so that part of the first photovoltaic panel 10 can be used for power generation.

[0062] Optionally, the two sets of connecting rods 22 have different lengths, allowing the second photovoltaic panel 20 to tilt relative to the first photovoltaic panel 10. For example, the second photovoltaic panel 20 can rotate relative to the first photovoltaic panel 10 about an axis along the first direction D1. The connecting rods 22 on the left and right sides of the second photovoltaic panel 20 have different lengths, allowing the second photovoltaic panel 20 to tilt left and right relative to the first photovoltaic panel 10. This can also adjust the degree of shading of the first photovoltaic panel 10 by the second photovoltaic panel 20 to a certain extent, thereby adjusting the power generation of the first photovoltaic panel 10.

[0063] Optionally, the first photovoltaic panel 10 and the second photovoltaic panel 20 have similar shapes but different areas. Preferably, the area of ​​the second photovoltaic panel 20 is greater than or equal to the area of ​​the first photovoltaic panel 10. As the main power generation photovoltaic panel, the second photovoltaic panel 20 can directly improve the power generation efficiency and power generation of the power generation device, while improving the uniformity of light, improving the anti-interference ability of the power generation device, and better adapting to the needs of different sites. On the basis of the above, when the second photovoltaic panel 20 is in the third position, the projection of the second photovoltaic panel 20 on the plane where the first photovoltaic panel 10 is located coincides with the first photovoltaic panel 10, or covers the first photovoltaic panel 10. It is understandable that the area of ​​the second photovoltaic panel 20 can also be smaller than the first photovoltaic panel 10. At this time, although the power generation power of the second photovoltaic panel 20 will be reduced, the shielding of the second photovoltaic panel 20 on the first photovoltaic panel 10 will be reduced, and the power generation power of the first photovoltaic panel 10 will increase to a certain extent.

[0064] Of course, the shapes of the first photovoltaic panel 10 and the second photovoltaic panel 20 may also be congruent, that is, the first photovoltaic panel 10 and the second photovoltaic panel 20 are constructed as the same photovoltaic panel, which can reduce the number of accessory models and thus save costs.

[0065] It can be understood that the movement of the sliding rod 21 relative to the sliding rail 11 and the rotation and / or extension of the connecting rod 22 are two relatively independent movements, which makes the movement of the second photovoltaic panel 20 relative to the first photovoltaic panel 10 along the first direction D1 and the movement of the second photovoltaic panel 20 relative to the first photovoltaic panel 10 along the vertical direction DH two relatively independent movements, and also makes the movement of the second photovoltaic panel 20 relative to the first photovoltaic panel 10 along the first direction D1 and the tilted rotation of the second photovoltaic panel 20 relative to the first photovoltaic panel 10 two relatively independent movements.

[0066] Optionally, the solar power generation device 1 is further provided with a support rod 23. When the second photovoltaic panel 20 moves away from the first photovoltaic panel 10 in the first direction D1, for example, when in the first position, the support rod 23 is used to support the second photovoltaic panel 20. It will be appreciated that the second photovoltaic panel 20 has a certain weight and is primarily supported by the sliding fit between the slide rail 11 and the slide rod 21. When the slide rod 21 extends out of the slide rail 11, the second photovoltaic panel 20 needs to be supported by the support rod 23 to ensure the stability of the solar power generation device 1.

[0067] Optionally, the support rod 23 is rotatably connected to the second photovoltaic panel 20. Preferably, the support rod 23 is arranged on the front side of the second photovoltaic panel 20, that is, the side of the second photovoltaic panel 20 that is away from the first photovoltaic panel 10 when the second photovoltaic panel 20 moves along the first direction to the extreme position deviating from the first photovoltaic panel 10. It can be understood that when the slide bar 21 extends out of the slide rail 11, the front side of the second photovoltaic panel 20 is the end away from the first photovoltaic panel 10 and is prone to tilting. Therefore, the support rod 23 is provided on the front side of the second photovoltaic panel 20. The support rod 23 is rotatably connected to the second photovoltaic panel 20 so that the support rod 23 can be retracted when the second photovoltaic panel 20 is in the second position or the third position. Preferably, when the support rod 23 is retracted, it is arranged parallel to the second photovoltaic panel 20.

[0068] In some embodiments of the present application, the support rod 23 is a telescopic rod to adapt to different installation heights of the solar power generation device 1.

[0069] Optionally, a buffer ring 30 is provided on the surface of the first photovoltaic panel 10 facing the second photovoltaic panel 20. A buffer ring 30 is also provided on the surface of the second photovoltaic panel 20 facing the first photovoltaic panel 10. The buffer ring 30 provides cushioning and shock absorption, preventing collision or friction between the first photovoltaic panel 10 and the second photovoltaic panel 20, thereby reducing mechanical damage and extending the service life of the solar power generation device 1. The shock absorption effect of the buffer ring 30 prevents mechanical vibration from spreading between the first photovoltaic panel 10 and the second photovoltaic panel 20. Therefore, the buffer ring 30 improves the stability of the solar power generation device 1 and ensures normal system operation. The buffer ring 30 protects the first photovoltaic panel 10 and the second photovoltaic panel 20 from mechanical damage, ensuring that the surfaces of the first photovoltaic panel 10 and the second photovoltaic panel 20 are free of scratches or hard defects. This significantly affects the light absorption and electrical conversion efficiency of the first photovoltaic panel 10 and the second photovoltaic panel 20, thereby improving power generation efficiency. Installing the buffer ring 30 can reduce the maintenance cost of the solar power generation device 1. Because the buffer ring 30 can reduce mechanical vibration and shock, thus preventing mechanical damage, the frequency of maintenance and replacement of the first photovoltaic panel 10 and the second photovoltaic panel 20 can be reduced, thereby reducing operating costs. The buffer ring 30 can also prevent dust accumulation and rainwater infiltration, preventing dust and rainwater from accumulating on the surface of the first photovoltaic panel 10.

[0070] The first photovoltaic panel 10 is a transparent panel. The second photovoltaic panel 20 is also a transparent panel. The transparent panels improve the overall power generation efficiency of the power generation device. Because the second photovoltaic panel 20 is transparent, sunlight can pass through it and shine onto the first photovoltaic panel 10, allowing the first and second photovoltaic panels 10 and 20 to generate electricity simultaneously, achieving dual solar energy utilization. Furthermore, the transparent photovoltaic panels not only generate electricity but also allow sunlight to pass through, illuminating the area below the power generation device and improving daylighting, making them suitable for a variety of scenarios.

[0071] The present application further provides a vehicle 2 comprising the aforementioned solar power generation device 1. As shown in Figures 8 and 9, the solar power generation device 1 is disposed on the top of the vehicle 2.

[0072] According to the vehicle 2 provided in this application, the photovoltaic panels with adjustable areas are used to increase the amount of electricity that can be generated by the solar power generation device 1, thereby increasing the cruising range of the vehicle 2; at the same time, the area of ​​the photovoltaic panels can be reasonably arranged according to the roof space and lighting conditions to maximize the area receiving sunlight as much as possible, thereby improving the efficiency of the solar power generation device 1.

[0073] In some embodiments of the present application, the first photovoltaic panel 10 is fixedly mounted on the roof of the vehicle to use solar energy to provide power for the vehicle and extend battery life.

[0074] In some embodiments of the present application, the first photovoltaic panel 10 is a transparent photovoltaic panel. The second photovoltaic panel 20 is a transparent photovoltaic panel. The photovoltaic panels can be used as vehicle sunroofs, enhancing the aesthetics of the vehicle roof without detracting from its appearance. They also offer high integration and power generation efficiency.

[0075] The specific application of the power generation device 1 in the vehicle 2 is described below.

[0076] In the following embodiment, the solar power generation device 1 includes a first photovoltaic panel 10 and a second photovoltaic panel 20 that are non-transparent and substantially identical in shape, four (two in a group) retractable connecting rods 22, two slide rails 11, two slide rods 21 adapted to the slide rails 11, and two retractable support rods 23.

[0077] Example 1

[0078] As shown in Figure 1, the second photovoltaic panel 20 is in the third position. When the first and second photovoltaic panels 10 and 20 are arranged parallel, the connecting rod 22 is tilted, and the first and second photovoltaic panels 10 and 20 are aligned. At this point, only the second photovoltaic panel 20 is illuminated and can generate electricity, while the first photovoltaic panel 10 is completely obscured by the second photovoltaic panel 20 and cannot generate electricity. The operating conditions of the solar power generation device 1 shown in this embodiment can be used in any vehicle state. The power generation capacity of the solar power generation device 1 is only equal to the standard power generation capacity of the upper photovoltaic panel.

[0079] Example 2

[0080] As shown in Figure 2, the second photovoltaic panel 20 is in the second position, the connecting rod 22 of the solar power generation device 1 is erected but not extended, and the second photovoltaic panel 20 has not moved laterally. At this time, the entire area of ​​the second photovoltaic panel 20 is fully illuminated and can generate electricity, while the first photovoltaic panel 10 is only partially illuminated and can generate a small amount of electricity. The operating conditions of the solar power generation device 1 shown in this embodiment can be used when the vehicle is driving or parked. Example 3

[0081] As shown in Figure 3, the connecting rod 22 of the solar power generation device 1 is erected and extended, and the second photovoltaic panel 20 has not slipped laterally. At this point, there is a significant height difference between the second photovoltaic panel 20 and the first photovoltaic panel 10. The first photovoltaic panel 10 is partially illuminated and generates a certain amount of power. This operating condition can be used when the vehicle is moving or parked. The solar power generation device 1 can generate up to the standard power generation of 1.2 photovoltaic panels.

[0082] Example 4

[0083] As shown in Figure 4, the second photovoltaic panel 20 of the solar power generation device 1 does not slide sideways. By controlling the length and inclination of the four retractable connecting rods 22 on the roof, the second photovoltaic panel 20 can be tilted to a certain degree. If the inclination of the second photovoltaic panel 20 is coordinated with the angle of incidence of sunlight, the second photovoltaic panel 20 can track the angle of sunlight, achieving maximum power generation from the sunlight. This solar power generation device 1 can be used while the vehicle is in motion, generating solar power equivalent to 1.05 to 1.3 standard photovoltaic panels.

[0084] Example 5

[0085] As shown in Figure 5, the second photovoltaic panel 20 of the solar power generation device 1 partially moves laterally. At this time, the entire area of ​​the second photovoltaic panel 20 is fully illuminated and can generate electricity. The first photovoltaic panel 10 has a portion of full illumination and another portion of weak illumination, and both can generate electricity. Because the second photovoltaic panel 20 only partially moves laterally, the second photovoltaic panel 20 can maintain good stability when the vehicle is parked. This state of the solar power generation device 1 can only be used when the vehicle is parked, and the center of gravity of the second photovoltaic panel 20 must be within the coverage area of ​​the first photovoltaic panel 10. The solar power generation capacity is at most equivalent to the standard power generation capacity of 1.5 photovoltaic panels.

[0086] Example 6

[0087] As shown in Figure 6, the second photovoltaic panel 20 is in the first position, that is, the second photovoltaic panel 20 is completely moved sideways, and the support rod 23 is supported to the ground. As shown in Figure 7, the support rod 23 can be further extended according to the actual application scenario to support the second photovoltaic panel 20. At this time, the entire area of ​​the second photovoltaic panel 20 on the upper layer and the first photovoltaic panel 10 on the lower layer are fully illuminated and can generate electricity. Because the support rod 23 is supported to the ground and the vehicle is in a parked state, the second photovoltaic panel 20 can have good structural stability. The maximum solar power generation capacity of this solar power generation device 1 may be the standard power generation capacity of 2 photovoltaic panels.

[0088] Example 7

[0089] When the vehicle is stopped, the second photovoltaic panel 20 of the solar power generation device 1 is fully moved sideways, with the support rod 23 resting on the ground. By monitoring the solar angle, the height or inclination of the connecting rod 22 and the height of the support rod 23 are controlled, allowing the second photovoltaic panel 20 to partially track the solar angle, achieving maximum solar power generation. This solar power generation device 1 can be used with the vehicle stopped, generating up to the equivalent of 2.3 standard photovoltaic panels.

[0090] In this application, the standard power generation of a photovoltaic panel is the average power generation per day when the solar surface of the photovoltaic panel is placed on a fixed horizontal surface.
