[0048] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0049] The following is for reference. Figures 1-8 This application describes a photovoltaic sunshade device provided in an embodiment, applied to a vehicle. The photovoltaic sunshade device has an deployed state and a retracted state, and includes a plurality of first photovoltaic modules 100 and at least one flexible shading element 200. It should be noted that "plural" includes two or more.

[0050] Each flexible shading element 200 is connected to two first photovoltaic modules 100. In the unfolded state, the first photovoltaic modules 100 and the flexible shading elements 200 are staggered along a first direction. In the stowed state, multiple first photovoltaic modules 100 are stacked along a second direction, with the first and second directions intersecting. It should be noted that the number, size, and shape of the first photovoltaic modules 100 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0051] For ease of understanding, in conjunction with the vehicle's direction, the first direction is parallel to the left and right directions, the second direction is parallel to the up and down directions, and the third direction is parallel to the front and back directions.

[0052] It should be noted that the first photovoltaic module 100 can provide power to the vehicle using sunlight; when parked, the first photovoltaic module 100 in its unfolded state, together with the flexible shading component 200, can also form a sunshade for resting outside the vehicle, which is convenient and practical.

[0053] Understandably, by using the flexible shading element 200, multiple first photovoltaic modules 100 are sequentially distributed along a first direction in the unfolded state, maximizing space utilization while generating electricity and providing shading, thus improving integration, energy efficiency, and comfort. Furthermore, the flexible shading element 200 allows multiple first photovoltaic modules 100 to be stacked along a second direction in the retracted state, making the photovoltaic shading device as compact as possible and improving space utilization. Simultaneously, the use of the flexible shading element 200 reduces the weight of the entire photovoltaic shading device and leverages its flexibility to achieve high efficiency in switching between the unfolded and retracted states.

[0054] For example, the flexible light-shielding element 200 includes, but is not limited to, a plastic sheet, a silicone sheet, or a velvet sheet.

[0055] In some embodiments, the surface of the flexible light-shielding member 200 is coated with a light-shielding coating to increase light-shielding performance and improve shading efficiency. Exemplarily, the light-shielding coating includes, but is not limited to, a UV film.

[0056] According to the photovoltaic shading device provided in the embodiments of this application, the first photovoltaic module 100 is connected by a flexible shading component 200, which optimizes the illumination area while balancing the shading effect, meets the requirements of lightweighting, and improves energy utilization.

[0057] In some embodiments, such as Figures 3 to 7 As shown, the first photovoltaic module 100 includes a photovoltaic panel 110, which has a first surface and a second surface along a second direction. The first surface is used to absorb solar energy.

[0058] In the unfolded state, the first surfaces of each photovoltaic panel 110 are located on the same side along the second direction;

[0059] In the stowed state, multiple photovoltaic panels 110 are stacked sequentially along the second direction, with the first surface of some photovoltaic panels 110 abutting against the first surface of adjacent photovoltaic panels 110, and the second surface of some photovoltaic panels 110 abutting against the second surface of adjacent photovoltaic panels 110.

[0060] It should be noted that the shape and size of the photovoltaic panel 110 can be designed according to actual needs, and this embodiment does not impose specific limitations on this. For example, the photovoltaic panel 110 is square, and its length direction is parallel to the front-to-back direction.

[0061] Understandably, in the unfolded state, the first side of each photovoltaic panel 110 faces the sun simultaneously to maximize solar energy absorption and thus improve power generation efficiency. At the same time, the second side of each photovoltaic panel 110, in conjunction with the flexible shading element 200, maximizes the shading area and improves shading efficiency. In the stowed state, the first side of some photovoltaic panels 110 abuts against the first side of adjacent photovoltaic panels 110, and the second side of some photovoltaic panels 110 abuts against the second side of adjacent photovoltaic panels 110. This protects the first side of the photovoltaic panels 110 during stacking, reducing the risk of scratches or damage and improving solar energy absorption rate.

[0062] For example, such as Figures 1 to 7 As shown, in the unfolded state, the three first photovoltaic modules 100 are sequentially distributed along the first direction. That is, the photovoltaic panels 110 corresponding to each of the three first photovoltaic modules 100 are defined as the first photovoltaic panel 110, the second photovoltaic panel 110, and the third photovoltaic panel 110, which are distributed sequentially from left to right. In the stowed state, the first photovoltaic panel 110, the second photovoltaic panel 110, and the third photovoltaic panel 110 are stacked sequentially from bottom to top. The second side of the first photovoltaic panel 110 faces down, the first side of the first photovoltaic panel 110 faces up and is in contact with the first side of the second photovoltaic panel 110, the second side of the second photovoltaic panel 110 is in contact with the second side of the third photovoltaic panel 110, and the first side of the third photovoltaic panel 110 faces up. This allows the photovoltaic panels to absorb solar energy even in the stowed state, thereby improving energy utilization efficiency.

[0063] In some embodiments, such as Figures 3 to 7 As shown, the first photovoltaic module 100 also includes a junction box 120, which is disposed on the first or second surface of the photovoltaic panel 110; wherein, in the retracted state, at least a portion of the projection of the junction box 120 is located within at least a portion of the flexible light-shielding member 200 along the second direction. It should be noted that the specific shape and size of the junction box 120 and the internal electronic components can be designed according to actual needs, and this embodiment does not impose specific limitations in this regard. For example, the junction box 120 is square.

[0064] It should be noted that the vehicle body 900 contains a controller, battery pack and inverter, etc. The junction box 120 is connected to the controller. The power is stored in the battery pack through the controller. The battery pack then changes the voltage through the inverter to power the electrical equipment.

[0065] Understandably, the junction box 120 is located on the first side of the photovoltaic panel 110 to facilitate electrical connections and maintenance operations in the unfolded state, and also to reduce the possibility of interference with the vehicle body 900. The junction box 120 is located on the second side of the photovoltaic panel 110, allowing it to be concealed in the unfolded state. This not only improves the aesthetics of the photovoltaic shading device but also reduces the junction box 120's erosion from rainwater, dust, etc., improving the reliability of the photovoltaic shading device. Simultaneously, in the retracted state, at least a portion of the junction box 120's projection along the vertical direction lies within at least a portion of the flexible light-shielding member 200. This allows adjacent photovoltaic panels 110 to be stacked while the junction box 120 is covered by the flexible light-shielding member 200, reducing the possibility of the junction box 120 and photovoltaic panel 110 being squeezed or scratched, and optimizing the compactness of the photovoltaic shading device.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, the first photovoltaic module 100 includes multiple junction boxes 120, which are spaced apart in the front-to-back direction to allow for segmented management and maintenance of the photovoltaic panel 110, thereby improving the flexibility and reliability of the first photovoltaic module 100. It should be noted that the number and specific distribution of the junction boxes 120 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0067] In some embodiments, a junction box 120 is disposed on a first surface of a photovoltaic panel 110; wherein, in the retracted state, at least partially adjacent projection portions of two photovoltaic panels 110 overlap along a second direction.

[0068] Understandably, the junction boxes 120 are located on the first side of the photovoltaic panel 110, meaning that in the unfolded state, all junction boxes 120 face upwards. In the retracted state, the junction box 120 of the bottom photovoltaic panel 110 faces upwards, which also reduces the possibility of interference with the vehicle body 900. Simultaneously, since at least some of the adjacent photovoltaic panels 110 in the vertical direction overlap, i.e., there is a certain misalignment between the stacked photovoltaic panels 110 in the front-back direction, the junction boxes 120 of the bottom photovoltaic panel 110 facing upwards and the junction boxes 120 of the top photovoltaic panel 110 facing upwards are spaced apart in the front-back direction. This also facilitates the separation of the wiring of the top photovoltaic panel 110 facing downwards and the bottom photovoltaic panel 110 in the front-back direction, reducing interference between the junction boxes 120 and adjacent photovoltaic panels 110, and improving the compactness and reliability of the photovoltaic shading device.

[0069] For example, in conjunction with the above example, such as Figure 7As shown, in the folded state, the junction box 120 disposed on the first photovoltaic panel 110 and the junction box 120 disposed on the third photovoltaic panel 110 are respectively located on both sides of the flexible light-shielding member 200 between the second photovoltaic panel 110 and the third photovoltaic panel 110. The junction box 120 disposed on the second photovoltaic panel 110 faces downward and is located on the flexible light-shielding member 200 between the first photovoltaic panel 110 and the second photovoltaic panel 110.

[0070] In some other embodiments, the junction box 120 may also be disposed on the second side of the photovoltaic panel 110, and the vehicle body 900 may have clearance holes. It should be noted that the number and shape of the clearance holes may be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0071] Understandably, the junction box 120 is located on the second side of the photovoltaic panel 110 so that, in the unfolded state, all junction boxes 120 face downwards and can be connected to electronic components inside the vehicle body 900 through the clearance holes, thus serving a concealing and protective function.

[0072] In some embodiments, the photovoltaic panel 110 is a flexible photovoltaic panel 110. Of course, in other embodiments, the photovoltaic panel 110 may also be a rigid photovoltaic panel 110. Rigid photovoltaic panels 110 are typically made of tempered glass and have extremely high durability and stability. This embodiment does not impose specific limitations on this.

[0073] Understandably, the flexible photovoltaic panel 110 is typically formed by using resin-encapsulated amorphous silicon as the main photovoltaic element layer, laid flat on a base plate made of flexible material. On one hand, the flexible photovoltaic panel 110 can better conform to the curvature of the vehicle body 900, maximizing the use of the space on the top surface of the vehicle body 900 for power generation; on the other hand, the flexible photovoltaic panel 110 can withstand a certain degree of bending and folding, reducing the possibility of damage during switching between unfolded and retracted states, and extending the service life of the first photovoltaic module 100. Furthermore, the flexible photovoltaic panel 110 is lighter than the rigid photovoltaic panel 110, further reducing the weight of the entire photovoltaic shading device.

[0074] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple first photovoltaic modules 100 form a photovoltaic module set. Multiple photovoltaic module sets are arranged sequentially along a third direction, which intersects with the first and second directions respectively. It should be noted that the number of photovoltaic module sets can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0075] Understandably, multiple photovoltaic modules are arranged sequentially along the front and rear directions to make fuller use of the roof area of ​​the vehicle body and achieve more efficient solar energy collection.

[0076] It should be noted that each flexible shading member 200 may be connected to only two adjacent first photovoltaic modules 100 in the same photovoltaic module set for disassembly and maintenance; or each flexible shading member 200 may be connected to at least two adjacent first photovoltaic modules 100 in multiple photovoltaic module sets, that is, the photovoltaic module sets are connected through the flexible shading member 200 to improve the efficiency of switching between the retracted state and the unfolded state. This embodiment does not impose specific restrictions on this.

[0077] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the photovoltaic shading device also includes a second photovoltaic module 300. All the first photovoltaic modules 100 are located on the same side of the second photovoltaic module 300 along a first direction, and the projection of the second photovoltaic module 300 along a second direction is located on the vehicle body 900. The connection method between the second photovoltaic module 300 and the vehicle body 900 includes, but is not limited to, threaded connection, welding, or plug-in connection. It should be noted that the specific structure of the second photovoltaic module 300 is similar to that of the first photovoltaic module 100, and no specific limitations are made here.

[0078] Understandably, by placing a second photovoltaic module 300 on one side of the photovoltaic module assembly, the efficiency of solar energy absorption is increased while optimizing the switching process between the deployed and retracted states. Simultaneously, the projection of the second photovoltaic module 300 along the second direction falls entirely on the vehicle body 900, reducing the possibility that the second photovoltaic module 300 may extend beyond the outline of the vehicle body 900 in both deployed and retracted states, thereby lowering the potential for aerodynamic problems or collision risks.

[0079] For example, the second photovoltaic module 300 is located on the far left, that is, arranged sequentially from left to right with the plurality of first photovoltaic modules 100. Of course, in other embodiments, the second photovoltaic module 300 may be located on the far right, which can be adjusted according to the driver's seat of the vehicle, and this embodiment does not impose a specific limitation on this.

[0080] It should be noted that the second photovoltaic module 300 and the leftmost first photovoltaic module 100 can be connected or spaced apart in the left-right direction. This embodiment does not impose specific restrictions on this.

[0081] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple second photovoltaic modules 300 are provided, and the multiple second photovoltaic modules 300 are spaced apart along a third direction and correspond one-to-one with the photovoltaic module set to increase the efficiency of solar energy absorption.

[0082] In some embodiments, such as Figure 1 and Figure 5As shown, along the first direction, the projection of the first photovoltaic module 100 located at the head end in the second direction is located on the vehicle body 900, for mounting on the vehicle body 900. It should be noted that the connection methods between the first photovoltaic module 100 and the vehicle body 900 include, but are not limited to, threaded connection, welding, or plug-in connection.

[0083] Understandably, the first photovoltaic module 100, located at the very left, serves as the starting point of the photovoltaic module assembly and plays a crucial anchoring role. By being mounted on the vehicle body 900, it provides a stable support point for the remaining first photovoltaic modules 100 within the assembly, ensuring the stability of the entire photovoltaic sunshade device when the vehicle is in motion or parked. Simultaneously, the vertical projection of the leftmost first photovoltaic module 100 falls within the vehicle body 900, reducing the possibility of the first photovoltaic module 100 protruding beyond the vehicle body 900 in a second or third direction when retracted, thus reducing air resistance and collision risk, and improving the reliability of the photovoltaic sunshade device.

[0084] In some embodiments, such as Figure 1 and Figure 5 As shown, in the unfolded state, along the first direction from front to back, the projection portion of the second first photovoltaic module 100 falls within the vehicle body 900.

[0085] It is understandable that, in the unfolded state, the projection of the second photovoltaic module 100 from left to right falls on the vehicle body 900, and combined with the fact that the projections of the first photovoltaic module 100 all fall on the vehicle body 900 in the retracted state, the strength of the connection between the first photovoltaic module 100 and the vehicle body 900 can be increased, thereby improving the reliability of the photovoltaic shading device.

[0086] In some embodiments, such as Figure 8 As shown, the photovoltaic shading device also includes at least one hinge 400, and two adjacent first photovoltaic modules 100 are hinged together by at least one hinge 400. The connection method between the hinge 400 and the first photovoltaic module 100 includes, but is not limited to, threaded connection, welding, or plug-in connection. The hinge 400 includes, but is not limited to, a 180° hinge.

[0087] Understandably, by setting the hinge 400, the angle changes and travel range of adjacent first photovoltaic modules 100 during the unfolding and retraction processes can be precisely controlled, reducing the possibility of loosening or swaying of the first photovoltaic modules 100 in the unfolded and retracted states. This improves the controllability of the flexible deformation of the flexible shading component 200 and enhances the overall reliability of the photovoltaic shading device. Furthermore, the hinge 400 also improves the switching efficiency of the photovoltaic shading device between the unfolded and retracted states, facilitating quick disassembly and maintenance.

[0088] In some embodiments, such as Figure 8 As shown, in the unfolded state, the hinge 400 is located on the side of the flexible light-shielding member 200 facing the vehicle body 900. That is, in the unfolded state, the hinge 400 is located below the flexible light-shielding member 200, which not only hides it but also reduces the possibility of interference between it and the junction box 120 in the retracted state, thereby improving the reliability of the photovoltaic sunshade device.

[0089] In some embodiments, such as Figure 8 As shown, multiple hinge members 400 are spaced apart along a third direction. That is, two adjacent first photovoltaic modules 100 are simultaneously connected to multiple hinge members 400 spaced apart along the front-back direction, thereby improving the stability of the connection between the first photovoltaic modules 100. It should be noted that the number and specific distribution of the hinge members 400 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0090] This application also provides a vehicle.

[0091] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the vehicle includes a body 900 and the aforementioned photovoltaic sunshade device, which is installed on the body 900. It should be noted that the vehicle includes, but is not limited to, a motorhome.

[0092] The vehicle provided according to the embodiments of this application optimizes the illumination area while balancing the shading effect, meets the vehicle's lightweight requirements, and improves energy utilization.

[0093] In some embodiments, such as Figure 5 and Figure 6 As shown, the vehicle also includes a first support member 810, one end of which is mounted to the vehicle body 900, and the other end is used to support the proximal end of the photovoltaic sunshade device extending outside the vehicle body 900 in the unfolded state. Exemplarily, the first support member 810 may include, but is not limited to, a folding bracket, a telescopic bracket, or an electric push rod. It should be noted that the specific structure of the first support member 810 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0094] Understandably, in the unfolded state, the first support member 810 is connected to the frame and the portion of the second first photovoltaic module 100 extending out of the vehicle body 900 from left to right, ensuring that the photovoltaic sunshade device can remain in the unfolded state when parked, thereby improving the efficiency of solar energy collection.

[0095] In some embodiments, such as Figure 5As shown, the vehicle also includes a second support member 820 for supporting the distal end of the photovoltaic sunshade device extending beyond the vehicle body 900 in the deployed state. The second support member 820 includes, but is not limited to, telescopic rods. It should be noted that the specific structure of the second support member 820 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0096] Understandably, in the unfolded state, the end of the second support rod away from the ground is connected to the first photovoltaic module 100 located on the far right, thereby increasing the support strength for the first photovoltaic module 100 and ensuring that the photovoltaic shading device can remain in the unfolded state when parked, thus improving the efficiency of solar energy collection.
