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

[0049] Reference below Figures 1-8 The photovoltaic sunshade device provided in an embodiment of the present application is described, and is applied to a vehicle. The photovoltaic sunshade device has an expanded state and a stowed state, and includes a plurality of first photovoltaic assemblies 100 and at least one flexible sunshade 200. It should be noted that the term "plurality" includes two or more.

[0050] Each flexible light shielding member 200 is connected to two first photovoltaic modules 100. In the deployed state, the first photovoltaic modules 100 and the flexible light shielding members 200 are staggered along a first direction. In the stowed state, the 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 are not specifically limited in this embodiment.

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

[0052] It should be noted that the first photovoltaic module 100 can use sunlight to provide electricity for the vehicle; when parked, the first photovoltaic module 100 in the unfolded state can also form a sun visor as a whole in conjunction with the flexible shading member 200 for rest outside the vehicle, which is convenient and practical.

[0053] It can be understood that the flexible shading member 200 enables the multiple first photovoltaic modules 100 to be sequentially distributed along the first direction in the deployed state, maximizing space utilization while simultaneously generating electricity and providing shade, thereby improving integration, energy efficiency, and comfort. Furthermore, the multiple first photovoltaic modules 100 can be stacked along the second direction in the stowed state, making the photovoltaic sunshade device as compact as possible and improving space utilization. Furthermore, the use of the flexible shading member 200 can reduce the weight of the entire photovoltaic sunshade device and utilize the inherent flexibility of the flexible shading member 200 to achieve flexibility and efficiency in switching the photovoltaic sunshade device between the deployed and stowed states.

[0054] Exemplarily, the flexible shading member 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 enhance light shielding performance and improve sun shading efficiency. For example, the light shielding coating includes but is not limited to a UV adhesive film.

[0056] According to the photovoltaic shading device provided in the embodiment of the present application, the flexible shading member 200 is used to connect the first photovoltaic component 100, which optimizes the illuminated area while balancing the shading effect, meets the lightweight requirements, and improves energy utilization.

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

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

[0059] In the storage state, multiple photovoltaic panels 110 are stacked in sequence along the second direction, the first surfaces of some photovoltaic panels 110 abut against the first surfaces of adjacent photovoltaic panels 110, and the second surfaces of some photovoltaic panels 110 abut against the second surfaces 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 any specific restrictions on this. For example, the photovoltaic panel 110 is square, and its length direction is parallel to the front-to-back direction.

[0061] It is understood that in the deployed state, the first surface of each photovoltaic panel 110 simultaneously faces the sun, maximizing solar energy absorption and thereby improving power generation efficiency. Simultaneously, the second surface of each photovoltaic panel 110 cooperates with the flexible shading member 200 to maximize the shading area and improve shading efficiency. In the stowed state, the first surface of some photovoltaic panels 110 abuts against the first surface of adjacent photovoltaic panels 110, while the second surface of some photovoltaic panels 110 abuts against the second surface of adjacent photovoltaic panels 110. This protects the first surface of the photovoltaic panels 110 during stowage, reduces the risk of scratches or damage during stacking, and improves solar energy absorption.

[0062] For example, Figures 1 to 7 As shown, in the unfolded state, the three first photovoltaic assemblies 100 are distributed sequentially along the first direction, that is, the photovoltaic panels 110 corresponding to the three first photovoltaic assemblies 100 are defined as the first photovoltaic panel 110, the second photovoltaic panel 110 and the third photovoltaic panel 110, and the first photovoltaic panel 110, the second photovoltaic panel 110 and the third photovoltaic panel 110 are distributed sequentially from left to right; in the stored state, the first photovoltaic panel 110, the second photovoltaic panel 110 and the third photovoltaic panel 110 are stacked in sequence from bottom to top, the second side of the first photovoltaic panel 110 faces downward, the first side of the first photovoltaic panel 110 faces upward and contacts the first side of the second photovoltaic panel 110, the second side of the second photovoltaic panel 110 contacts the second side of the third photovoltaic panel 110, and the first side of the third photovoltaic panel 110 faces upward, so that solar energy can be absorbed even in the stored state, thereby improving energy utilization.

[0063] In some embodiments, as Figures 3 to 7 As shown, the first photovoltaic assembly 100 further includes a junction box 120, which is disposed on the first or second surface of the photovoltaic panel 110. In the stowed state, along the second direction, 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. It should be noted that the specific shape and size of the junction box 120, as well as the electronic components within it, can be designed based on actual needs and are not specifically limited in this embodiment. For example, the junction box 120 is square in shape.

[0064] It should be noted that the vehicle body 900 is equipped with a controller, a battery pack and an inverter, etc. The junction box 120 is connected to the controller, and the electricity 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] It is understood that the junction box 120 is disposed on the first side of the photovoltaic panel 110, facilitating electrical connection and maintenance operations in the deployed state and reducing the possibility of interference with the vehicle body 900. The junction box 120 is disposed on the second side of the photovoltaic panel 110, allowing it to be hidden in the deployed state. This not only enhances the aesthetics of the photovoltaic sunshade device but also protects the junction box 120 from rain, dust, and the like, thereby improving the reliability of the photovoltaic sunshade device. Furthermore, in the stowed state, at least a portion of the junction box 120's vertical projection is located within at least a portion of the flexible sunshade member 200. This allows adjacent photovoltaic panels 110 to be stacked while the junction box 120 is covered by the flexible sunshade member 200, reducing the possibility of squeezing and scratching the junction box 120 and photovoltaic panels 110 and optimizing the compactness of the photovoltaic sunshade device.

[0066] In some embodiments, as Figure 1 and Figure 2 As shown, the first photovoltaic assembly 100 includes a plurality of junction boxes 120, which are spaced apart in the front-to-back direction to facilitate segmented management and maintenance of the photovoltaic panels 110, thereby improving the flexibility and reliability of the first photovoltaic assembly 100. It should be noted that the number and specific distribution of the junction boxes 120 can be designed according to actual needs and are not specifically limited in this embodiment.

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

[0068] It is understood that the junction boxes 120 are disposed on the first surface of the photovoltaic panels 110, meaning that in the deployed state, all junction boxes 120 face upward. In the stowed state, the junction box 120 of the bottommost photovoltaic panel 110 faces upward, which also reduces the possibility of interference with the vehicle body 900. Furthermore, because at least some of the two photovoltaic panels 110 adjacent in the vertical direction partially overlap, i.e., there is a certain amount of misalignment between the stacked photovoltaic panels 110 in the front-to-back direction, the junction box 120 facing upward on the bottom photovoltaic panel 110 is spaced apart in the front-to-back direction from the junction box 120 facing upward on the top photovoltaic panel 110. This also facilitates the connection of the top photovoltaic panel 110 facing downward and the spacing of the junction box 120 from the bottom photovoltaic panel 110 in the front-to-back direction. This reduces interference between the junction boxes 120 and adjacent photovoltaic panels 110, thereby improving the compactness and reliability of the photovoltaic sunshade device.

[0069] For example, in combination with the above example, Figure 7As shown, in the storage state, the junction box 120 arranged on the first photovoltaic panel 110 and the junction box 120 arranged on the third photovoltaic panel 110 are respectively located on both sides of the flexible shading member 200 between the second photovoltaic panel 110 and the third photovoltaic panel 110, and the junction box 120 arranged on the second photovoltaic panel 110 faces downward and is located on the flexible shading member 200 between the first photovoltaic panel 110 and the second photovoltaic panel 110.

[0070] In other embodiments, the junction box 120 may also be disposed on the second surface of the photovoltaic panel 110, and a clearance hole may be provided on the vehicle body 900. It should be noted that the number and shape of the clearance holes may be designed according to actual needs and are not specifically limited in this embodiment.

[0071] It is understandable that the junction boxes 120 are arranged on the second side of the photovoltaic panel 110 so that in the unfolded state, all the junction boxes 120 are facing downward and can be connected to the electronic devices in the vehicle body 900 through the avoidance holes, thereby playing a role of hiding and protection.

[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, which is typically made of tempered glass and has extremely high durability and stability, and this embodiment does not impose any specific limitations on this.

[0073] It is understood that flexible photovoltaic panels 110 are often composed of resin-encapsulated amorphous silicon as the primary photovoltaic element layer, laid flat on a flexible substrate. On the one hand, flexible photovoltaic panels 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, flexible photovoltaic panels 110 can withstand a certain degree of bending and folding, reducing the possibility of damage during transitions between the deployed and stowed states, thereby extending the service life of the first photovoltaic assembly 100. Furthermore, flexible photovoltaic panels 110 are lighter than rigid photovoltaic panels 110, further reducing the weight of the entire photovoltaic sunshade device.

[0074] In some embodiments, as Figure 1 and Figure 2 As shown, a plurality of first photovoltaic modules 100 form a photovoltaic module assembly. A plurality of photovoltaic module assemblies are provided, and the plurality of photovoltaic module assemblies are sequentially distributed along a third direction, which intersects the first direction and the second direction. It should be noted that the number of photovoltaic module assemblies can be designed based on actual needs and is not specifically limited in this embodiment.

[0075] It is understandable that the plurality of photovoltaic assembly sets are arranged in sequence along the front-to-back direction to more fully utilize the top surface area of ​​the vehicle body 900 and achieve more efficient solar energy collection.

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

[0077] In some embodiments, as Figure 1 、 Figure 2 、 Figure 5 and Figure 7 As shown, the photovoltaic sunshade device also includes a second photovoltaic assembly 300. All first photovoltaic assemblies 100 are located on the same side of the second photovoltaic assembly 300 along the first direction, and the projection of the second photovoltaic assembly 300 along the second direction is located on the vehicle body 900. The connection between the second photovoltaic assembly 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 assembly 300 is similar to that of the first photovoltaic assembly 100 and is not specifically limited here.

[0078] As can be appreciated, by placing the second photovoltaic assembly 300 on one side of the photovoltaic assembly assembly, the efficiency of solar energy absorption is increased while optimizing the transition process between the deployed and stowed states. Furthermore, the projection of the second photovoltaic assembly 300 along the second direction falls entirely on the vehicle body 900, reducing the possibility of the second photovoltaic assembly 300 extending beyond the outline of the vehicle body 900 in both the deployed and stowed states, thereby minimizing the possibility of aerodynamic issues or collision risks.

[0079] For example, the second photovoltaic assembly 300 is located on the far left, i.e., arranged sequentially from left to right with the plurality of first photovoltaic assemblies 100. Of course, in other embodiments, the second photovoltaic assembly 300 may also be located on the far right, which can be adjusted according to the driving position of the vehicle, and this embodiment does not impose any specific limitations on this.

[0080] It should be noted that the second photovoltaic assembly 300 and the leftmost first photovoltaic assembly 100 may be connected or spaced apart in the left-right direction, and this embodiment does not impose any specific limitation on this.

[0081] In some embodiments, as Figure 1 and Figure 2 As shown, a plurality of second photovoltaic components 300 are provided, and the plurality of second photovoltaic components 300 are spaced apart along the third direction and correspond one-to-one to the photovoltaic component sets to increase the efficiency of absorbing solar energy.

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

[0083] It is understood that the first photovoltaic module 100 located at the front end, i.e., the leftmost end, serves as the starting point of a photovoltaic module assembly and plays a key anchoring role. By being installed on the vehicle body 900, it provides a stable support point for the remaining first photovoltaic modules 100 in the photovoltaic module assembly, ensuring the stability of the entire photovoltaic sunshade device when the vehicle is driving or parked. At the same time, the projection of the leftmost first photovoltaic module 100 in the vertical direction falls within the vehicle body 900, thereby reducing the possibility of the first photovoltaic module 100 protruding from the vehicle body 900 in the second or third direction when stored, reducing air resistance and collision risks, and improving the reliability of the photovoltaic sunshade device.

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

[0085] It can be understood that, in the unfolded state, the projection of the second first 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 in the stored state all fall on the vehicle body 900, 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 use of the photovoltaic shading device.

[0086] In some embodiments, as Figure 8 As shown, the photovoltaic sunshade device further includes at least one hinge 400, and two adjacent first photovoltaic assemblies 100 are hingedly connected via the at least one hinge 400. The connection between the hinge 400 and the first photovoltaic assemblies 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] It can be understood that by providing hinges 400, the angular change and travel range of adjacent first photovoltaic assemblies 100 during deployment and retraction are precisely controlled, reducing the possibility of loosening or dangling of the first photovoltaic assemblies 100 in the deployed and retracted states, improving the controllability of the flexible deformation of the flexible shading member 200, and enhancing the overall reliability of the photovoltaic sunshade device. Furthermore, the use of hinges 400 also improves the efficiency of switching between the deployed and retracted states of the photovoltaic sunshade device, facilitating quick assembly and disassembly and maintenance.

[0088] In some embodiments, as Figure 8 As shown, in the unfolded state, the hinge 400 is located on the side of the flexible shade 200 facing the vehicle body 900. That is, the hinge 400 is located below the flexible shade 200 in the unfolded state, hiding it while reducing the possibility of interference with the junction box 120 in the retracted state, thereby improving the reliability of the photovoltaic sunshade device.

[0089] In some embodiments, as Figure 8 As shown, multiple hinges 400 are spaced apart along the third direction. That is, two adjacent first photovoltaic modules 100 are simultaneously connected to multiple hinges 400 spaced apart along the front-to-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 hinges 400 can be designed according to actual needs and are not specifically limited in this embodiment.

[0090] An embodiment of the present application also provides a vehicle.

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

[0092] According to the vehicle provided in the embodiment of the present application, the illumination area is optimized while balancing the sunshade effect, meeting the lightweight requirements of the vehicle and improving energy utilization.

[0093] In some embodiments, as Figure 5 and Figure 6 As shown, the vehicle further includes a first support member 810. One end of the first support member 810 is mounted to the vehicle body 900, and the other end is used to support the proximal portion of the photovoltaic sunshade device extending outside the vehicle body 900 when deployed. For example, the first support member 810 includes, 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 is not specifically limited in this embodiment.

[0094] It can be understood that in the unfolded state, the first support member 810 is respectively connected to the frame and the part of the second first photovoltaic component 100 extending out of the vehicle body 900 from left to right, ensuring that the photovoltaic shading device can be maintained in the unfolded state when parking, thereby improving the efficiency of collecting solar energy.

[0095] In some embodiments, as Figure 5As shown, the vehicle further includes a second support member 820 for supporting the distal end of the photovoltaic sunshade device extending outside the vehicle body 900 when deployed. The second support member 820 includes, but is not limited to, a telescopic rod. It should be noted that the specific structure of the second support member 820 can be designed based on actual needs and is not specifically limited in this embodiment.

[0096] It can be understood that, in the unfolded state, the end of the second support rod away from the ground is connected to the first photovoltaic assembly 100 located on the far right, thereby increasing the support strength of the first photovoltaic assembly 100, ensuring that the photovoltaic shading device can be maintained in the unfolded state when parking, and improving the efficiency of collecting solar energy.
