[0002] At present, solar power generation materials mostly use crystalline silicon wafers, perovskite materials, cadmium telluride materials, etc., and are generally used in open fields, deserts, roofs and large-area buildings, and through photovoltaic conversion, solar energy is converted into electric energy and transmitted into the national power grid, and then the electricity is collected uniformly to solve most of the electricity demand. However, the current photovoltaic conversion rate is only about 15%-22%, and usually a large area needs to be used to convert effective electricity, so the current photovoltaic conversion on vehicles, ships and other vehicles still stays at the surface of the awareness level, in addition, the available area of such vehicles is usually small, and there are usually irregular surfaces, especially small vehicles, and photovoltaic panels are strictly laid and coated, and it is difficult to apply them on vehicles, ships and other vehicles.

Detailed Implementation

[0055] The present application will be further described below with reference to specific embodiments. It should be understood that these specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present application.

[0056] In this application, the following definitions and methods are provided to better define this application and to guide those skilled in the art in its practice. Unless otherwise stated, the terms are to be understood in accordance with their conventional usage by those skilled in the art.

[0057] As used herein, the term "comprising" should be interpreted as inclusive and open-ended, not exclusive. Specifically, when used in the specification and claims, the term "comprising" and its variations mean including the specified features, steps, or components. These terms should not be construed as excluding the presence of other features, steps, or components.

[0058] As used herein, the term “optional” means that the events or circumstances described below may, but are not required to, occur, including both when they occur and when they do not.

[0059] In this document, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] Wherever a range of values ​​is given herein, the range includes its endpoints, as well as all individual integers and fractions within the range, and also includes each narrower range formed by all the various possible combinations of those endpoints and internal integers and fractions, to form a subgroup of a larger group of values ​​within the same extent as each of those narrower ranges is explicitly given.

[0061] In a first aspect of this application, a means of transportation is provided, with reference to Figures 1-3 The device includes: a body 10, at least one solar panel 20, a heat dissipation assembly 30, and an energy storage battery 40. The outer surface of the body 10 includes a bonding surface 11, at least a portion of which is irregularly shaped; the solar panel 20 is bonded to the bonding surface 11; the heat dissipation assembly 30 is disposed between at least one solar panel 20 and the bonding surface 11; and the solar panel 20 is electrically connected to the energy storage battery 40.

[0062] In this application, "irregular surface" refers to an irregular, non-standard surface shape, including but not limited to irregular surfaces that vary in a two-dimensional plane, such as wavy or sawtooth shapes; or irregular curved surfaces that involve three-dimensional space, such as spheres, ellipsoids, hyperboloids, or single curved surfaces; or complex surfaces formed by the combination of the irregular surface and the irregular curved surface.

[0063] The vehicle of the first aspect of this application has at least the following technical effects: The solar panel is attached to the surface of the vehicle body, and the attachment area includes irregularly shaped surfaces. This utilizes the irregularly shaped surface areas of the vehicle body, improving the surface utilization rate of the vehicle and increasing the total attachment area between the vehicle body surface and the solar panel. This, in turn, improves the effective conversion efficiency of the solar panel. Combined with a large-capacity energy storage battery, this can increase the driving range. Furthermore, the solar panel generates heat during the conversion of light energy into electrical energy, causing the panel to overheat, especially in summer. By installing a heat dissipation component between the solar panel and the attachment surface on the outer surface of the vehicle body, the solar panel can be cooled in a timely manner, reducing the safety risks to the energy storage battery, discomfort to personnel, or adverse effects on the quality of transported products caused by the increased temperature of the vehicle body.

[0064] In some embodiments of this application, reference is made to Figure 4 It is understood that the solar panel 20 may include a flexible substrate 21 and solar cells 22. The flexible substrate 21 is bonded to the bonding surface 11, and the solar cells 22 are disposed on the side of the flexible substrate 21 away from the bonding surface 11. This arrangement allows the solar cells to be fixed to the flexible substrate before being bonded to the vehicle body, facilitating electrical connections between the solar cells and ensuring smooth fabrication processes.

[0065] In some embodiments of this application, the solar cell 22 can be a crystalline silicon cell. Optionally, the crystalline silicon cell can include a monocrystalline silicon cell or a polycrystalline silicon cell. Further alternatively, the crystalline silicon cell can be a monocrystalline silicon cell.

[0066] In some embodiments of this application, the solar cell 22 can be a thin-film solar cell. Using a thin-film solar cell not only further facilitates the bonding of the solar cell to the outer surface of the vehicle, but also facilitates the cutting of the cell to obtain a solar cell of the required size and / or shape for the solar panel.

[0067] In some embodiments of this application, the solar cell 22 can be a thin-film solar cell commonly used in the photovoltaic field. Exemplarily, the solar cell 22 can include, but is not limited to, crystalline silicon thin-film solar cells, gallium nitride thin-film solar cells, perovskite thin-film solar cells, cadmium telluride thin-film solar cells, or gallium arsenide thin-film solar cells. Optionally, the crystalline silicon thin-film solar cell can include, but is not limited to, monocrystalline silicon thin-film solar cells or polycrystalline silicon thin-film solar cells.

[0068] In some embodiments of this application, the shape of the crystalline silicon solar cell may include, but is not limited to, a rectangle, which may be a square or a rectangle.

[0069] In some embodiments of this application, the solar cell 22 can be either a single large cell or an array of cells formed by multiple small cells. For example, see reference... Figure 4 To illustrate, taking a monocrystalline silicon solar cell as an example, the solar cell 22 may include multiple sub-solar cells 221, which can be connected in series and / or in parallel. The array of solar cells formed by multiple small cells helps reduce the stress and strain of the solar cells when they are bonded to the bonding surface, thereby further facilitating the bonding of the solar panel to the surface of the vehicle body, especially the bonding of the solar panel to irregularly shaped surfaces, reducing the risk of solar cell failure due to large deformation caused by bonding the solar cells to irregularly shaped surfaces. It is understood that the source of the multiple sub-solar cells 221 is not particularly limited; they can be mass-produced according to the required size, commercially available, or obtained by cutting large-sized solar cells that are either prepared or commercially available.

[0070] In some embodiments of this application, the irregularity of the irregular surface affects the bonding effect between the solar panel 20 and the vehicle body 10. The bonding effect between the solar panel 20 and the vehicle body 10 is mainly affected by the stress and strain of the solar cell 22. For solar cells 22 with better flexibility, such as gallium nitride thin film cells, perovskite thin film cells, cadmium telluride thin film cells, or gallium arsenide thin film cells, the size of the solar cell 22 has a smaller impact when bonding with the surface of the vehicle body 10. However, for crystalline silicon cells with relatively poor flexibility, such as monocrystalline silicon cells, the size of the cell will significantly affect the bonding effect between the solar panel 20 and the vehicle body 10.

[0071] In some embodiments of this application, when the maximum curvature of the bonding surface 11 is greater than or equal to 5° and less than 10°, the area of ​​the sub-solar cell 221 can be less than or equal to 83 cm². 2 For example, the area of ​​the sub-solar cell 221 can be less than or equal to 83 cm². 2 82cm 2 80cm 2 75cm 2 70cm 2 65cm 2 60cm 2 56cm 2 55cm 2 50cm 2 45cm 2 40cm 2 38cm 2 37cm 2 35cm 2 30cm2 25cm 2 22cm 2 21cm 2 20cm 2 18cm 2 15cm 2 14cm 2 13cm 2 10cm 2 8cm 2 Or 3cm 2 ...etc., or it can be a range of any of the above values. For example, when the maximum curvature of the bonding surface 11 is greater than or equal to 5° and less than 10°, the area of ​​the sub-solar cell 221 can be 56 cm². 2 ~83cm 2 Optionally, the sub-solar cell 221 can be rectangular or square. As a specific example, the sub-solar cell 221 can be square with a side length of 91 mm. In some embodiments of this application, when the maximum arc of the bonding surface 11 is greater than or equal to 10° and less than 20°, the area of ​​the sub-solar cell 221 can be less than or equal to 56 cm². 2 For example, the area of ​​the sub-solar cell 221 can be less than or equal to 56 cm². 2 55cm 2 50cm 2 45cm 2 40cm 2 38cm 2 37cm 2 35cm 2 30cm 2 25cm 2 22cm 2 21cm 2 20cm 2 18cm 2 15cm 2 14cm 2 13cm 2 10cm 2 8cm 2 Or 3cm 2 ...etc., or it can be a range of any of the above values. For example, when the maximum curvature of the bonding surface 11 is greater than or equal to 10° and less than 20°, the area of ​​the sub-solar cell 221 can be 38 cm². 2 ~56cm 2Optionally, the sub-solar cell 221 can be rectangular or square. As a specific example, the sub-solar cell 221 is rectangular, such as having a length of 91 mm and a width of 61 mm.

[0072] In some embodiments of this application, when the maximum curvature of the bonding surface 11 is greater than or equal to 20° and less than 30°, the area of ​​the sub-solar cell 221 can be less than or equal to 38 cm². 2 For example, the area of ​​the sub-solar cell 221 can be less than or equal to 38 cm². 2 37cm 2 35cm 2 30cm 2 25cm 2 22cm 2 21cm 2 20cm 2 18cm 2 15cm 2 14cm 2 13cm 2 10cm 2 8cm 2 Or 3cm 2 ...etc., or it can be a range of any of the above values. For example, when the maximum curvature of the bonding surface 11 is greater than or equal to 20° and less than 30°, the area of ​​the sub-solar cell 221 can be 22 cm². 2 ~38cm 2 Alternatively, the sub-solar cell 221 can be rectangular or square. As a specific example, the sub-solar cell 221 can be square with a side length of 61 mm.

[0073] In some embodiments of this application, when the maximum curvature of the bonding surface 11 is greater than or equal to 30°, the area of ​​the sub-solar cell 221 can be less than or equal to 22 cm². 2 For example, the area of ​​the sub-solar cell 221 can be less than or equal to 22 cm². 2 21cm 2 20cm 2 18cm 2 15cm 2 14cm 2 13cm 2 10cm 2 8cm 2 Or 3cm 2 ...etc., or it can be a range of any of the above values. For example, when the maximum curvature of the bonding surface 11 is greater than or equal to 30°, the area of ​​the sub-solar cell 221 can be 13 cm².2 ~22cm 2 Alternatively, the sub-solar cell 221 can be rectangular or square. As a specific example, the sub-solar cell 221 can be square with a side length of 46 mm.

[0074] In some specific embodiments of this application, taking a commercially available crystalline silicon solar cell with dimensions of 182mm × 182mm as an example, it can be cut according to the maximum curvature of the bonding surface 11 to obtain a sub-solar cell 221 with an area of ​​1 / 4 to 1 / 24 of the original commercially available solar cell size. It should be noted that when cutting the solar cell, it can be cut only along the length and / or width direction of the solar cell, for example:

[0075] When the maximum curvature of the bonding surface 11 is greater than or equal to 5° and less than 10°, the crystalline silicon solar cell can be cut into four equal parts to obtain multiple sub-solar cells 221 with a length × width of 91mm × 91mm. In a single solar panel 20, the solar cell 22 can be obtained by connecting multiple sub-solar cells 221 of this size in series and / or in parallel.

[0076] When the maximum curvature of the bonding surface 11 is greater than or equal to 10° and less than 20°, the crystalline silicon solar cell can be cut into six equal parts, such as six sub-solar cells 221 with a length × width of 91mm × 61mm. In a single solar panel 20, the solar cell 22 can be obtained by connecting multiple sub-solar cells 221 of this size in series and / or in parallel.

[0077] When the maximum curvature of the bonding surface 11 is greater than or equal to 20° and less than 30°, the crystalline silicon solar cell can be cut into nine equal parts, such as six sub-solar cells 221 with a length × width of 61mm × 61mm. In a single solar panel 20, the solar cell 22 can be obtained by connecting multiple sub-solar cells 221 of this size in series and / or in parallel.

[0078] When the maximum curvature of the bonding surface 11 is greater than or equal to 30°, the crystalline silicon solar cell can be cut into sixteen, eighteen, or 24 equal parts. For example, it can be cut into sixteen sub-solar cells 221 with a length × width of 45.5mm × 45.5mm. In a single solar panel 20, the solar cell 22 can be obtained by connecting multiple sub-solar cells 221 of this size in series and / or in parallel.

[0079] The maximum curvature of the bonding surface 11 reflects the structure of the area with the greatest irregularity of the irregular surface to a certain extent. This ensures that the maximum curvature of the bonding surface 11 corresponds to the size of the solar cell 22 or sub-solar cell 221. This can better balance the relationship between reducing the workload of bonding the solar cell to the flexible substrate, the series or parallel resistance between solar cells, and the bonding effect between the solar panel and the vehicle body. It reduces the workload of bonding the solar cell to the flexible substrate and the series or parallel resistance between solar cells while achieving a good bonding effect between the solar panel and the vehicle body.

[0080] In some specific embodiments of this application, taking a crystalline silicon solar cell as an example, after cutting a whole crystalline silicon solar cell into four to sixteen smaller solar cells and then connecting and welding multiple smaller solar cells in series, the photovoltaic conversion efficiency can be greater than or equal to 82% of the photovoltaic conversion efficiency of the solar cell before cutting, such as 85%, 87%, 90%, or 93% of the photovoltaic conversion efficiency of the solar cell before cutting.

[0081] In some specific embodiments of this application, the arc diameter of the bonding surface 11 can be greater than or equal to 90 mm, for example, it can be greater than or equal to 90 mm, 95 mm, 100 mm, 105 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 170 mm, 180 mm, 190 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, 650 mm, 700 mm, 750 mm, or 800 mm, etc., or can be any range of the above values. This helps to reduce the irregularity of the irregular surface, thereby improving the bonding effect between the solar panel and the vehicle body, reducing the risk of solar panel failure due to large deformation caused by bonding the solar cell to the irregular surface, and also helping to increase the utilization area of ​​the vehicle surface, using as much of the body surface as possible to lay solar panels for photovoltaic power generation.

[0082] In some embodiments of this application, the bonding method between the solar panel 20 and the bonding surface 11 is not particularly limited, and those skilled in the art can choose according to actual needs. For example, the solar panel 20 and the bonding surface 11 can be bonded by one or more of riveting, welding, threaded connection, and bonding.

[0083] In some embodiments of this application, the solar panel 20 and the bonding surface 11 can be bonded together. This not only facilitates operation but also improves the bonding effect between the two.

[0084] In some embodiments of this application, reference is made to Figure 4 It is understood that when the solar panel 20 includes a flexible substrate 21 and solar cells 22, the bonding method between the flexible substrate 21 and the bonding surface 11, as well as the connection method between the solar cells 22 and the flexible substrate 21, are not particularly limited, and those skilled in the art can choose according to actual needs. For example, the flexible substrate 21 and the bonding surface 11 can be bonded by one or more of riveting, welding, threaded connection, and bonding. For example, the solar cells 22 and the flexible substrate 21 can be connected by one or more of riveting, welding, threaded connection, and bonding, and are disposed on the side of the flexible substrate 21 away from the bonding surface 11.

[0085] In some embodiments of this application, when the solar panel 20 includes a flexible substrate 21 and solar cells 22, the flexible substrate 21 and the bonding surface 11 can be bonded together. This not only facilitates operation but also improves the structural stability of the solar panel and its bonding effect with the bonding surface.

[0086] In some embodiments of this application, when the solar panel 20 includes a flexible substrate 21 and a solar cell 22, the solar cell 22 can be bonded to the side of the flexible substrate 21 away from the bonding surface 11.

[0087] In some embodiments of this application, reference is made to Figure 1 It is understood that a vehicle may include multiple solar panels 20, which may be connected in series and / or in parallel. For example, all solar panels 20 may be connected in series. Alternatively, all solar panels 20 may be connected in parallel. Yet another example is that some solar panels 20 may be connected in series, and the remaining solar panels may be connected in parallel. It is understood that solar panels (cells) connected in series have the same current, and solar panels (cells) connected in parallel have the same voltage.

[0088] In some embodiments of this application, reference is made to Figures 5-6 It is understood that the heat dissipation component 30 may include an air duct 31, and a first groove 111 may be provided on the contact surface 11. The first groove 111 can form an air duct 31 with openings at both ends by the solar panel 20. In this way, natural wind can be used to cool the solar panel in a timely manner.

[0089] In some embodiments of this application, the air duct 31 can extend from the front to the rear of the vehicle, that is, the length direction of the air duct can extend from the front to the rear of the vehicle. It is understood that the front of the vehicle refers to the side of the vehicle closest to its direction of travel, and the rear of the vehicle refers to the side of the vehicle away from its direction of travel. This can improve the cooling effect of natural wind on the solar panels.

[0090] In some embodiments of this application, the inlet of the air duct 31 may be provided with a first filter (not shown); and / or, the outlet of the air duct 31 may be provided with a second filter (not shown). This helps to prevent debris such as fallen leaves from entering the air duct and affecting the flow of natural wind within the air duct, thereby affecting the cooling effect on the solar panels.

[0091] In some embodiments of this application, combined with Figures 5-8 It is understood that a ventilation pipe 311 can also be provided in the air duct 31. The height of the ventilation pipe 311 along the depth direction of the first groove 111 is less than the depth of the first groove 111, and multiple air holes 312 are provided on the side of the ventilation pipe 311 facing the solar panel 20.

[0092] In some embodiments of this application, reference is made to Figure 5 It is understood that a single solar panel 20 may have one or more first grooves 111 between it and the bonding surface 11, and the multiple first grooves 111 are spaced apart along the width direction of the air duct 31. The presence of multiple first grooves facilitates the formation of multiple air ducts between the same solar panel and the vehicle body, increasing the heat dissipation area and improving the cooling effect on the solar panel.

[0093] In some embodiments of this application, reference is made to Figure 2 and Figure 9 It is understood that the heat dissipation component 30 may include a condenser 32, and a second groove 112 may be provided on the contact surface 11.

Thus, the condenser can be used to cool the solar panel in a timely manner.

[0094] In some embodiments of this application, the condenser 32 can be arranged in a U-shape, S-shape, ring shape, I-shape, or finger shape within the accommodating space. This is beneficial for extending the distribution length of the condenser within the accommodating space, increasing the heat dissipation area, and improving the cooling effect on the solar panel.

The presence of multiple second grooves facilitates the formation of multiple accommodating spaces for placing condensation components between the same solar panel and the vehicle body, increasing the heat dissipation area and improving the cooling effect on the solar panel.

[0128] In some embodiments of this application, the method of manufacturing a vehicle may further include: forming a second groove in the mating surface, and disposing a condenser in the second groove, such that the condenser is located within the accommodating space enclosed by the second groove and the solar panel.
