DETAILED DESCRIPTION

[0034] The following are preferred implementations of the present application. It should be noted that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.

[0035] Please refer to Figures 1 to 6. Figure 1 is a schematic diagram of a foldable cover applied to a mobile device in one embodiment of the present application. Figure 2 is a cross-sectional schematic diagram of the foldable cover shown in Figure 1 applied to a mobile device. Figure 3 is a schematic diagram of the three-dimensional structure of the foldable cover in one embodiment of the present application.

Figure 5 is a schematic diagram of one cover assembly of the foldable cover shown in Figure 3 when it is folded. Figure 6 is a schematic diagram of two cover assemblies of the foldable cover shown in Figure 3 when they are folded.

[0036] The foldable cover 2 provided in this embodiment is used to be installed on the trunk 1b of the mobile device 1 to cover or open the opening of the trunk 1b. The foldable cover 2 includes a plurality of cover assemblies 10 that are rotatably connected in sequence. Each of the cover assemblies 10 includes a photovoltaic panel 11 and a substrate 12. The photovoltaic panel 11 is used to absorb light energy and convert it into electrical energy. Any two adjacent cover assemblies 10 are electrically connected to each other, and along the arrangement direction of the plurality of cover assemblies 10, the cover assembly 10 provided at one end is also used to electrically connect to the energy storage device 3 located in the trunk 1b to charge the energy storage device 3.

[0037] The foldable cover 2 is a foldable and tiltable cover composed of multiple cover assemblies 10 that are connected in a rotatable manner. The folding function is achieved by the folding of the cover assemblies 10. Therefore, the foldable cover 2 has an unfolded state and a folded state. The unfolded state refers to the state in which the multiple cover assemblies 10 are flattened, while the folded state refers to the state in which the cover assemblies 10 are folded. Furthermore, the folding of different numbers of cover assemblies 10 results in the foldable cover 2 having a variety of different folding states.

[0038] The mobile device 1 includes, but is not limited to, a pickup truck, a truck, a van, a snowmobile, or other vehicles with an open trunk 1b. The foldable cover 2 can be installed on the side of the trunk 1b so that when the foldable cover 2 is in the unfolded state, it can cover the opening of the trunk 1b, thereby effectively protecting the items in the trunk 1b, and when it is folded, the opening of the trunk 1b is opened to facilitate the user to take out the items in the trunk 1b. Specifically, the cover assembly 10 can open the opening to different degrees when it is folded to other cover assemblies 10, and the user can fold it according to needs. For example, in this embodiment and the following, the foldable cover 2 is schematically illustrated as including three cover assemblies 10. The cover assembly 10 located at the rear of the trunk 1b, that is, the cover assembly 10 away from the cab 1a, can be rotated and overlapped to the cover assembly 10 located in the middle to reveal the opening portion of the trunk 1b, so as to facilitate the taking and placing of items. Furthermore, the cover assembly 10 located in the middle can be rotated again so that the cover assembly 10 in the middle and the cover assembly 10 located at the rear of the trunk 1b can be overlapped together to the cover assembly 10 close to the cab 1a, so as to reveal more opening areas of the trunk 1b, which is conducive to taking and placing larger volumes and more items.

[0039] In the related art, each cover assembly 10 only includes a substrate 12, thereby achieving the function of covering and opening the opening of the trunk 1b. However, the function of the foldable cover 2 is relatively simple and cannot meet the needs of users. Therefore, in this embodiment, the cover assembly 10 is equipped with a photovoltaic panel 11, i.e., a solar panel, on the basis of the substrate 12. The substrate 12 is mainly used for support. The photovoltaic panel 11 can absorb light energy and convert it into electrical energy to achieve photoelectric conversion. When the foldable cover 2 is in the unfolded state, the photovoltaic panel 11 is arranged upward to better receive sunlight and other light energy. Since the foldable cover 2 includes a plurality of cover assemblies 10 and each cover assembly 10 includes a photovoltaic panel 11, two adjacent cover assemblies 10 can be electrically connected to each other, i.e., two adjacent photovoltaic panels 11 can be electrically connected to each other, thereby concentrating the converted electrical energy together.

[0040] In addition, in this embodiment, the electric energy converted by the foldable cover 2 is not directly used to charge the mobile device 1, but is used to charge the energy storage device 3 provided in the trunk 1b. The energy storage device 3 is a rechargeable energy storage device 3 added to the trunk 1b. The user can carry the energy storage device 3 and use the energy storage device 3 to provide energy for other devices. For example, the user can use the energy storage device 3 to achieve lighting, boiling water, cooking and other tasks outdoors. After use, it is put back into the trunk 1b and electrically connected to the cover assembly 10 at one end. In this way, the electric energy converted by the photovoltaic panels 11 in the multiple cover assemblies 10 can be used to charge the energy storage device 3 through the cover assembly 10 at this end, thereby achieving the purpose of energy saving and environmental protection.

[0041] In summary, the foldable cover 2 in this embodiment can not only cover the trunk 1b, but also realize photoelectric conversion, and use the converted electrical energy to charge the energy storage device 3 in the trunk 1b, thereby realizing the charging function, making the functions of the foldable cover 2 diversified and meeting the needs of users.

[0042] Please refer to Figure 2 again. In this embodiment, the mobile device 1 includes a driving cabin 1a and the trunk 1b. The energy storage device 3 is arranged away from the driving cabin 1a. The cover plate assembly 10 away from the driving cabin 1a among the multiple cover plate assemblies 10 is electrically connected to the energy storage device 3.

[0043] The driving compartment 1a is the portion of the mobile device 1 that the user drives and can also be referred to as the front of the vehicle. The side wall of the trunk 1b, which is away from the driving compartment 1a, can be rotated to open the trunk 1b from the side. Therefore, the energy storage device 3 can be positioned in the trunk 1b away from the driving compartment 1a, that is, close to the rotatable side wall, making it easier for the user to access the energy storage device 3. The multiple cover assemblies 10 are arranged in sequence from close to the driving compartment 1a to away from the driving compartment 1a. Therefore, this embodiment can utilize the photovoltaic panels 11 in the cover assembly 10 away from the driving compartment 1a to achieve electrical connection with the energy storage device 3, thereby facilitating the user's installation and removal of the energy storage device 3 and the foldable cover 2.

[0044] Please refer to Figure 7, which is a cross-sectional view of another embodiment of the present invention showing a foldable cover applied to a mobile device. In this embodiment, the cover assembly 10 near the cockpit 1a among the multiple cover assemblies 10 is also used to electrically connect to the movable solar panel 4.

[0045] The removable solar panel 4 is not the foldable cover 2 of this application, but rather another type of solar panel. This solar panel also performs photoelectric conversion and is mobile, allowing users to carry it with them. For example, when outdoors, users can place the removable solar panel 4 on the bottom surface for photoelectric conversion. In other words, the foldable cover 2 provided in this application is a fixed solar panel fixedly mounted on the mobile device 1, while the removable solar panel 4 is a user-installed solar panel that can be placed in the trunk 1b or in the cab 1a.

[0046] In this embodiment, the cover plate assembly 10 close to the cockpit 1a among the multiple cover plate assemblies 10 can be used to electrically connect the movable solar panel 4, so that the number of solar panels can be increased and the charging efficiency can be improved.

[0047] Optionally, when the user needs to electrically connect the cover assembly 10 near the cockpit 1a to the movable solar panel 4, the user can first fold the rear cover assembly 10, thereby making it easier for the user to electrically connect the cover assembly 10 near the cockpit 1a to the movable solar panel 4. Of course, in other embodiments, the cover assembly 10 near the cockpit 1a can be electrically connected to the movable solar panel 4 without folding the cover assembly 10.

[0048] Please refer to Figure 8, which is a cross-sectional schematic diagram of the foldable cover and the energy storage device in one embodiment of the present application. In this embodiment, the side of the substrate 12 in each of the cover assemblies 10 facing away from the photovoltaic panel 11 is provided with an interface 13 for electrically connecting to the photovoltaic panel 11, and the foldable cover 2 also includes at least one first wire assembly 21 and a second wire assembly 22, and the opposite ends of each first wire assembly 21 are used to electrically connect the two interfaces 13 of the two adjacent cover assemblies 10, and one end of the second wire assembly 22 is electrically connected to the interface 13 of the cover assembly 10 provided at one end, and the other end is used to electrically connect to the energy storage device 3.

[0049] When the foldable cover 2 is in the unfolded state, the photovoltaic panel 11 is arranged on the top and the substrate 12 is arranged on the bottom. In this embodiment, an interface 13 for electrically connecting the photovoltaic panel 11 is provided on the side of the substrate 12 facing away from the photovoltaic panel 11, that is, the interface 13 is provided below the substrate 12, so as to facilitate the use of the interface 13 to electrically connect the photovoltaic panels 11 in two adjacent cover assemblies 10.

[0050] The foldable cover 2 can also be provided with at least one first wire assembly 21 and one second wire assembly 22, each of which has different functions. One end of each first wire assembly 21 is electrically connected to the interface 13 of a cover assembly 10, and the other end of the first wire assembly 21 is electrically connected to the interface 13 of an adjacent cover assembly 10. In this way, the photovoltaic panels 11 in two adjacent cover assemblies 10 can be electrically connected together using one first wire assembly 21. Specifically, when the foldable cover 2 includes three cover assemblies 10, two first wire assemblies 21 are required. One first wire assembly 21 connects the interface 13 of the first cover assembly 10 with the interface 13 of the second cover assembly 10, and the other wire assembly connects the interface 13 of the second cover assembly 10 with the interface 13 of the third cover assembly 10. In this way, the three cover assemblies 10 can be electrically connected together using two first wire assemblies 21.

[0051] In addition, one end of the second wire assembly 22 can be electrically connected to the interface 13 of the cover assembly 10 at the end, that is, electrically connected to the interface 13 of the cover assembly 10 away from the cockpit 1a, and the other end of the second wire assembly 22 can be used to electrically connect to the energy storage device 3, so that the electric energy converted by the foldable cover 2 can be transmitted to the energy storage device 3 through the second wire assembly 22, thereby charging the energy storage device 3.

[0052] In summary, multiple cover plate assemblies 10 can be connected together through the interface 13 , the first wire assembly 21 , and the second wire assembly 22 to charge the energy storage device 3 .

[0053] Optionally, the first conductor assembly 21 and the second conductor assembly 22 may have the same structure or different structures. When the first conductor assembly 21 and the second conductor assembly 22 have the same structure, conductor assemblies in different areas and with different functions are named differently.

[0054] Please refer to Figures 9 and 10. Figure 9 is a bottom view of the foldable cover in one embodiment of the present application. Figure 10 is a partially enlarged schematic diagram of the foldable cover shown in Figure 9. In this embodiment, the first wire assembly 21 includes a first wire 211 and a second wire 212. One end of the first wire 211 is connected to the interface 13 of one of the cover assemblies 10, and one end of the second wire 212 is connected to the interface 13 of the adjacent cover assembly 10. The other end of the first wire 211 is electrically connected to the other end of the second wire 212.

[0055] The foldable cover 2 also includes a second wire 212 of the cover assembly 10 arranged at the other end, one end of the second wire 212 is electrically connected to the interface 13 of the cover assembly 10 at the other end, and the other end of the second wire 212 is used to electrically connect to the movable solar panel 4.

[0056] The first wire assembly 21 is not a single wire, but consists of two wires: a first wire 211 and a second wire 212. One end of the first wire 211 is connected to the interface 13 of one cover assembly 10, one end of the second wire 212 is connected to the interface 13 of an adjacent cover assembly 10, and the other end of the first wire 211 is electrically connected to the other end of the second wire 212. In this way, the first wire 211 and the second wire 212 can be used to electrically connect two adjacent cover assemblies 10.

[0057] Specifically, when the foldable cover 2 includes three cover assemblies 10, one end of the first wire 211 in one first wire assembly 21 is electrically connected to the interface 13 of the first cover assembly 10, one end of the second wire 212 is electrically connected to the interface 13 of the second cover assembly 10, and the other end of the first wire 211 is electrically connected to the other end of the second wire 212. One end of the first wire 211 in another first wire assembly 21 is electrically connected to the interface 13 of the second cover assembly 10, one end of the second wire 212 is electrically connected to the interface 13 of the third cover assembly 10, and the other end of the first wire 211 is electrically connected to the other end of the second wire 212.

[0058] Alternatively, the first conductor 211 can be a two-core wire, 500 mm long, with the red wire stripped 75 mm and the black wire stripped 25 mm at one end, thereby connecting to the positive and negative poles of the interface 13. The other end is connected to a 50A Anderson plug. The second conductor 212 can also be a two-core wire, 500 mm long, with the red wire stripped 25 mm and the black wire stripped 75 mm at one end, thereby connecting to the positive and negative poles of the interface 13 of the adjacent cover assembly 10. The other end is connected to a 50A Anderson plug. By plugging the two Anderson plugs together, the other end of the first conductor 211 is electrically connected to the other end of the second conductor 212.

[0059] In addition, this embodiment can also add a second wire 212, and make one end of the second wire 212 electrically connected to the interface 13 of the cover assembly 10 at the other end, that is, the interface 13 of the cover assembly 10 near the cockpit 1a. The other end of the second wire 212 can be used to electrically connect to an external movable solar panel. In other words, this embodiment can also add a second wire 212 to the interface 13 of the cover assembly 10 near the cockpit 1a side, and use the second wire 212 to achieve electrical connection with the movable solar panel 4. Optionally, an Anderson plug can also be provided on the second wire 212 to achieve electrical connection with the movable solar panel 4.

[0060] Please refer to Figure 11, which is a schematic diagram of the foldable cover, electrical connection wire, and movable solar panel shown in Figure 10. In this embodiment, the other end of the second wire 212 is also used to connect to one end of the electrical connection wire 5, and the other end of the electrical connection wire 5 is used to connect to the movable solar panel 4.

[0061] This embodiment may also include an electrical connection cable 5, with one end of the electrical connection cable 5 electrically connected to the other end of the second conductive wire 212, and the other end of the electrical connection cable 5 electrically connected to the movable solar panel 4. In other words, since the movable solar panel 4 is placed on the ground to receive solar energy, it may be relatively far from the mobile device 1. Therefore, this embodiment does not directly connect the movable solar panel 4 with the second conductive wire 212. Instead, an extension cable, namely the electrical connection cable 5, is used to electrically connect the foldable cover 2 and the movable solar panel 4, facilitating connection between the two. The length of the electrical connection cable 5 can be set and selected according to needs.

[0062] Please refer to Figures 9 and 12 together. Figure 12 is a partially enlarged schematic diagram of the foldable cover shown in Figure 9 when it is in conjunction with the energy storage device. In this embodiment, the second wire assembly 22 includes a third wire 221 and a fourth wire 222. One end of the third wire 221 is electrically connected to the interface 13 of the cover assembly 10 provided at one end, and the other end of the third wire 221 is electrically connected to the other end of the fourth wire 222. One end of the fourth wire 222 is used to electrically connect to the energy storage device 3.

[0063] The second wire assembly 22 is not a single wire, but consists of two wires: a third wire 221 and a fourth wire 222. One end of the third wire 221 is electrically connected to the interface 13 of the cover assembly 10 provided at one end, and the other end of the third wire 221 is electrically connected to the other end of the fourth wire 222. One end of the fourth wire 222 is used to electrically connect to the energy storage device 3. In this way, the third wire 221 and the fourth wire 222 can be used to connect the foldable cover 2 and the energy storage device 3 together.

[0064] Alternatively, the third conductor 221 can be a two-core wire, 500 mm long, with the red wire stripped 75 mm and the black wire stripped 25 mm at one end, so that it can be connected to the positive and negative terminals of the interface 13. The other end is connected to a 50A Anderson plug. The fourth conductor 222 can also be a two-core wire, 1000 mm long, with one end connected to a 50A Anderson plug, which plugs into the Anderson plug of the third conductor 221. The other end is connected to a 30A Anderson plug for connection to the energy storage device 3.

[0065] In this embodiment, when the multiple cover plate assemblies 10 are folded, the first wire 211 and the second wire 212 can be connected together, or the first wire 211 and the second wire 212 can be separated; the second wire assembly 22 can be separated from the energy storage device 3.

[0066] When it is necessary to open the trunk 1b or to electrically connect the cover assembly 10 near the cab 1a to the movable solar panel 4, the cover assembly 10 can be folded. Since the distance between two adjacent cover assemblies 10 increases when folded, the length of the first wire 211 and the second wire 212 is lengthened when unfolded, so that the two wires can still be connected together even if folded. Alternatively, the first wire 211 and the second wire 212 can be separated, and then the cover assembly 10 can be folded. As for the second wire assembly 22, it needs to be separated from the energy storage device 3 to facilitate the separation of the cover assembly 10 away from the cab 1a and the energy storage device 3.

[0067] Please refer to Figures 1-2 again. This embodiment also provides a mobile device 1, including a driving cabin 1a, a trunk 1b, an energy storage device 3, and a foldable cover 2 as provided in the above embodiment of this application. The foldable cover 2 is installed on the trunk 1b and electrically connected to the energy storage device 3 to charge the energy storage device 3.

[0068] The mobile device 1, the driving cabin 1a, the trunk 1b, the energy storage device 3, and the foldable cover 2 have been described in detail above in this application, and will not be repeated in this embodiment. The mobile device 1 provided in this embodiment, by adopting the foldable cover 2 provided above in this application, can not only use the foldable cover 2 to achieve the function of shielding the trunk 1b, but also use the foldable cover 2 to achieve photoelectric conversion, thereby charging the energy storage device 3 in the trunk 1b, thus diversifying the functions of the foldable cover 2.

[0069] Please refer to Figures 2 and 7 again. In this embodiment, the mobile device 1 also includes a movable solar panel 4 and an electrical connection line 5. The cover assembly 10 in the foldable cover 2 away from the cockpit 1a is electrically connected to the energy storage device 3, and the cover assembly 10 close to the cockpit 1a is electrically connected to one end of the electrical connection line 5, and the other end of the electrical connection line 5 is electrically connected to the movable solar panel 4.

[0070] The movable solar panel 4 and the electrical connection line 5 have been described in detail above and will not be repeated in this embodiment. This embodiment uses the electrical connection line 5 to electrically connect the cover assembly 10 near the cab 1a and the movable solar panel 4, thereby reducing the difficulty of connecting the two.
