DETAILED DESCRIPTION

[0042] 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.

[0043] Please refer to Figures 1 to 3. Figure 1 is a schematic diagram of the three-dimensional structure of the cover assembly in one embodiment of the present application. Figure 2 is an exploded view of the cover assembly shown in Figure 1. Figure 3 is a cross-sectional schematic diagram of the cover assembly shown in Figure 1. The cover assembly 1 provided in this embodiment includes a photovoltaic panel 30, an adhesive layer 20, and a cover 10. The photovoltaic panel 30 has a light-absorbing surface 301 and a backlight surface 302 disposed opposite to each other, and the adhesive layer 20 is bonded to the backlight surface 302. The cover 10 is bonded to the side of the adhesive layer 20 facing away from the photovoltaic panel 30. The cover 10 includes a support layer 110 and a reinforcement layer 120. The reinforcement layer 120 is provided on at least one side of the support layer 110. The support layer 110 includes a plastic support layer 110 or an aluminum support layer 110.

[0044] The cover assembly 1 is a structure that covers other components and can be used to shield them. For example, the cover assembly 1 can be applied to the trunk 82 of a mobile device 3, such as a truck, van, or pickup truck, to shield the opening of the trunk 82, thereby improving the waterproof and dustproof properties of the trunk 82 and enhancing the security of the trunk 82, thereby preventing theft of items within the trunk 82.

[0045] The cover plate assembly 1 primarily comprises a photovoltaic panel 30, an adhesive layer 20, and a cover plate 10. The adhesive layer 20 is bonded between the photovoltaic panel 30 and the cover plate 10. In other words, the photovoltaic panel 30 and the cover plate 10 are bonded together via the adhesive layer 20. Optionally, the adhesive layer 20 includes, but is not limited to, polyethylene terephthalate (PET) glue, epoxy resin glue, ketoprofen (KPF) liposome gel, and the like. Furthermore, KPF glue can be used for the adhesive layer 20 to further improve the surface flatness of the adhesive layer 20, thereby better bonding the adhesive layer 20 to the cover plate 10 and enhancing bonding performance.

[0046] The cover plate 10 is mainly used to support the photovoltaic panel 30, and plays a role in supporting and fixing the photovoltaic panel 30. The photovoltaic panel 30 can also be called a solar panel, which is mainly used to absorb natural light, non-natural light and other light and convert light energy into electrical energy to power other electrical equipment. Therefore, the photovoltaic panel 30 has a light-absorbing surface 301 that absorbs light, and a backlight surface 302 opposite to the light-absorbing surface 301. The above content can also be understood as one side of the adhesive layer 20 is on the backlight surface 302, and the other side is bonded to the cover plate 10. Compared with the traditional cover plate 10, the present embodiment integrates the photovoltaic panel 30 on the cover plate 10. While achieving the purpose of covering the opening of the trunk 82, the photovoltaic panel 30 in the cover plate assembly 1 can also be used to convert light energy into electrical energy, thereby providing electrical energy for electrical equipment.

[0047] The cover plate 10 mainly includes a support layer 110 and a reinforcement layer 120, wherein the support layer 110 is mainly used to support the photovoltaic panel 30. The material of the support layer 110 is mainly plastic or aluminum, and the aluminum material can be aluminum or aluminum alloy. Optionally, the material of the plastic includes but is not limited to polyethylene (PP). As can be seen from the background technology, the support structure currently used to support the photovoltaic panel 30 is a support member made of ferroalloy or ferroalloy profile 70, which causes the product to be overweight, the manufacturing cost is high, it is not conducive to the transportation and installation of the product, and it is easy to absorb heat without insulation. The use of a plastic support layer 110 or an aluminum support layer 110 in this application can reduce the weight of the cover plate 10 under the same size and volume, achieve lightweight products, reduce production and manufacturing, installation and transportation costs, and have good insulation effect without absorbing heat. In addition, the support layer 110 made of polypropylene has corrosion resistance and a long service life, and can be recycled and reused without causing pollution to the environment.

[0048] In addition, the reinforcement layer 120 plays a reinforcing role. The reinforcement layer 120 cooperates with the support layer to improve the structural strength of the cover plate 10, thereby effectively supporting the cover plate 10. Optionally, there can be only one reinforcement layer 120, which is disposed on one side of the support layer 110. For example, the reinforcement layer 120 can be disposed between the support layer 110 and the adhesive layer 20, or the reinforcement layer 120 can be disposed on the side of the support layer 110 facing away from the adhesive layer 20. Optionally, there can be two reinforcement layers 120, which are disposed on opposite sides of the support layer 110, with one reinforcement layer 120 disposed between the support layer 110 and the adhesive layer 20 and the other reinforcement layer 120 disposed on the side of the support layer 110 facing away from the adhesive layer 20.

[0049] Alternatively, the reinforcement layer 120 may be made of, but is not limited to, fiberglass reinforced plastic (FRP). FRP is a plastic reinforced with glass fiber in an unsaturated polyester, epoxy resin, and phenolic resin matrix. Reinforced plastics using glass fiber or its products as reinforcement are known as fiberglass reinforced plastics, or FRP. The FRP reinforcement layer 120, when combined with the photovoltaic panel 30, offers strong impact and pressure resistance, as well as excellent thermal insulation properties.

[0050] In summary, the cover plate 10 provided in this embodiment, while supporting the photovoltaic panel 30, can reduce the product quality of the photovoltaic panel 30 assembly, achieving product lightweighting, reducing manufacturing, installation, and transportation costs, while also providing excellent thermal insulation without absorbing heat. Furthermore, the composite cover plate 10 exhibits excellent waterproof properties, improving the adhesion between the cover plate 10 and the photovoltaic panel 30 and preventing delamination between the cover plate 10 and the photovoltaic panel 30. Furthermore, the cover plate 10 can be processed through cutting and thermoforming processes, making it easy to manufacture and maintain.

[0051] Please refer to Figures 4 and 5. Figure 4 is a schematic diagram of the three-dimensional structure of the support layer in the second embodiment of this application. Figure 5 is a partial top view of the support layer shown in Figure 4. In this embodiment, the support layer 110 includes a plurality of interconnected annular support portions 111. Each of the annular support portions 111 has a through hole 112 extending from the light absorbing surface 301 to the backlight surface 302. The aperture of the through hole 112 is 5 mm to 15 mm.

[0052] The support layer 110 is not a solid layer structure, but rather a support structure composed of multiple interconnected and spliced ​​annular support portions 111. Each annular support portion 111 has a through hole 112 extending from the light-absorbing surface 301 to the backlight surface 302. In other words, the annular support portion 111 is provided with through holes 112 extending vertically. In this case, the support layer 110 can also be referred to as a PP honeycomb core. Thus, by using the annular support portions 111, the weight of the support layer 110 and the cover plate 10 can be further reduced, in addition to supporting the photovoltaic panel 30.

[0053] Furthermore, the diameter of the through hole 112 can be 5 mm to 15 mm. If the diameter of the through hole 112 is less than 5 mm, the support layer 110 becomes heavier and cannot meet the lightweight requirements of the cover assembly 1. If the diameter of the through hole 112 is greater than 15 mm, the hole size is too large, which will reduce the structural strength of the support layer 110 and cannot meet the requirements of supporting the photovoltaic panel 30. Optionally, the diameter of the through hole 112 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, or 15 mm.

[0054] Please refer to Figure 6, which is a cross-sectional schematic diagram of the components of the cover plate in the third embodiment of the present application. In this embodiment, the cover plate 10 also includes a heat-insulating layer 130 provided between the support layer 110 and the reinforcement layer 120. Adding the heat-insulating layer 130 between the support layer 110 and the reinforcement layer 120 can further improve the heat-insulating performance of the cover plate 10 and is not easy to absorb heat. The material of the heat-insulating layer 130 includes but is not limited to polyethylene terephthalate (PET). Further optionally, the heat-insulating layer 130 includes but is not limited to non-woven fabric. Optionally, the number of heat-insulating layers 130 can also be one or two. When the number of heat-insulating layers 130 is one, the heat-insulating layer 130 can be provided on the side of the support layer 110 close to the photovoltaic panel 30, or on the side of the support layer 110 away from the photovoltaic panel 30. When the number of heat-insulating layers 130 is two, the two heat-insulating layers 130 can be provided on opposite sides of the support layer 110.

[0055] Please refer to Figures 2 and 7 together. Figure 7 is a cross-sectional schematic diagram of the cover plate assembly in the fourth embodiment of the present application. In this embodiment, the number of the reinforcing layer 120 and the number of the thermal insulation layer 130 are both two. The two reinforcing layers 120 are disposed on opposite sides of the support layer 110, and each thermal insulation layer 130 is disposed between the support layer 110 and the reinforcing layer 120.

[0056] In this embodiment, there are two reinforcement layers 120 and two insulation layers 130. The two reinforcement layers 120 are positioned on opposite sides of the support layer 110, and each insulation layer 130 is positioned between the support layer 110 and the reinforcement layer 120. In other words, the cover plate 10 is stacked with reinforcement layers 120, insulation layers 130, support layer 110, insulation layers 130, and reinforcement layers 120 in this order, from the light-absorbing surface 301 to the backlight surface 302 of the photovoltaic panel 30. By placing reinforcement layers 120 and insulation layers 130 on opposite sides of the support layer 110, the strength and insulation properties of the plastic can be further improved.

[0057] Please refer to Figure 7 again. In this embodiment, the thickness of the reinforcement layer 120 close to the photovoltaic panel 30 is thinner than the thickness of the reinforcement layer 120 away from the photovoltaic panel 30. This embodiment allows the thickness of the supporting layer 110 to be different on opposite sides, thereby achieving a differentiated configuration. Specifically, the thickness of the reinforcement layer 120 close to the photovoltaic panel 30 can be thinner than the thickness of the reinforcement layer 120 away from the photovoltaic panel 30. In other words, the thickness of the reinforcement layer 120 bonded to the adhesive layer 20 should be thinner, and the thickness of the lower reinforcement layer 120 should be thicker. The lower reinforcement layer 120 can be used primarily to improve the structural strength of the cover plate 10, while the upper reinforcement layer 120 can reduce the overall thickness of the cover plate 10, thereby achieving a lighter and thinner cover plate assembly 1.

[0058] Optionally, the thickness of the reinforcement layer 120 near the photovoltaic panel 30 is 0.1 mm to 0.5 mm, and the thickness of the reinforcement layer 120 away from the photovoltaic panel 30 is 0.5 mm to 1.5 mm. Further, optionally, the thickness of the reinforcement layer 120 near the photovoltaic panel 30 is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm. The thickness of the reinforcement layer 120 away from the photovoltaic panel 30 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

[0059] In this embodiment, the thickness of the support layer 110 is 7 mm to 15 mm. Optionally, the thickness of the support layer 110 is 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, or 15 mm.

[0060] In this embodiment, the thickness of the heat insulating layer 130 is 0.05 mm to 0.15 mm. Optionally, the thickness of the heat insulating layer 130 is 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, or 0.15 mm.

[0061] In this embodiment, the total thickness of the cover plate 10 is 7.7 mm to 17.15 mm. Specifically, the total thickness of the cover plate 10 is the sum of the thicknesses of the aforementioned layers. By controlling the thicknesses of the different layers, the total thickness of the cover plate 10 can be controlled. Optionally, the total thickness of the cover plate 10 is 7.7 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm, 13 mm, 13.5 mm, 14 mm, 14.5 mm, 15 mm, 15.5 mm, 16 mm, 16.5 mm, 17 mm, or 17.15 mm.

[0062] In this embodiment, the thickness of the photovoltaic panel 30 is 2 mm to 2.5 mm. Optionally, the thickness of the photovoltaic panel 30 is 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, or 2.5 mm.

[0063] Please refer to Figure 8, which is a cross-sectional schematic diagram of the cover plate assembly in the fifth embodiment of the present application. In this embodiment, the photovoltaic panel 30 includes a cell 310 and four layers of hot melt adhesive 320 (EVA) provided on opposite sides of the cell 310. The hot melt adhesive 320 can protect the central cell 310. Two layers of hot melt adhesive 320 are provided on the side of the cell 310 facing away from the cover plate 10, and two layers of hot melt adhesive 320 are provided on the side of the cell 310 close to the cover plate 10. As for the specific structure of the photovoltaic panel 30, this embodiment is not limited here.

[0064] In this embodiment, the thickness of the cover plate assembly 1 is 10 mm to 20 mm. Optionally, the thickness of the cover plate assembly 1 is 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm.

[0065] Please refer to Figure 9, which is a cross-sectional schematic diagram of the cover plate assembly in the sixth embodiment of the present application. In this embodiment, there are multiple photovoltaic panels 30, and the multiple photovoltaic panels 30 are bonded to the cover plate 10 via the adhesive layer 20 array. The cover plate assembly 1 also includes a flat layer 40, which is provided on the cover plate 10 where the photovoltaic panels 30 are not provided, and on the photovoltaic panels 30. The surface of the flat layer 40 facing away from the cover plate 10 is flush.

[0066] The number of photovoltaic panels 30 can be multiple, and multiple photovoltaic panels 30 are arranged in an array on the cover plate 10. In other words, each photovoltaic panel 30 is bonded to the cover plate 10 through the adhesive layer 20. The above content can also be understood as that the cover plate 10 is not provided with a whole layer of photovoltaic panels 30, but is composed of a plurality of photovoltaic panels 30 arranged in an array. In addition to the above components, the cover plate assembly 1 may also include a flat layer 40. The flat layer 40 is arranged in an area on the cover plate 10 where no photovoltaic panels 30 are arranged, and is arranged on the side of the photovoltaic panel 30 away from the cover plate 10, thereby playing the role of covering and protecting the photovoltaic panel 30. Optionally, the flat layer 40 is light-transmitting, and light can pass through the flat layer 40 and be projected onto the photovoltaic panel 30. And the surface of the flat layer 40 facing away from the cover plate 10 is flush, that is, the upper surface of the flat layer 40 is flush, which can improve the flatness of the cover plate assembly 1. Optionally, the material of the flat layer 40 includes but is not limited to ethylene-tetrafluoroethylene copolymer. The use of the above material can make the flat layer 40 have the characteristics of heat resistance, wear resistance, scratch resistance, etc.

[0067] Please refer to Figures 10 and 11. Figure 10 is a top view of the cover assembly from another perspective in another embodiment of the present application. Figure 11 is a cross-sectional schematic diagram of a cover assembly in the seventh embodiment of the present application. In this embodiment, the cover assembly 1 also includes a first electrical connector 61 and an interface 50. The interface 50 is fixed to the side of the cover 10 facing away from the photovoltaic panel 30 and corresponds to the photovoltaic panel 30. One end of the first electrical connector 61 is electrically connected to the photovoltaic panel 30, and the other end passes through the adhesive layer 20 and is electrically connected to the interface 50 with the cover 10.

[0068] The cover assembly 1 may also include a first electrical connector 61 and an interface 50, wherein the interface 50 is fixed to the side of the cover 10 facing away from the photovoltaic panel 30, that is, the photovoltaic panel 30 is arranged above the cover 10, and the interface 50 is arranged below the cover 10. The interface 50 corresponds to the photovoltaic panel 30 to facilitate the connection of the first electrical connector 61. One end of the first electrical connector 61 is electrically connected to the photovoltaic panel 30, and the other end passes through the adhesive layer 20 and is electrically connected to the interface 50 with the cover 10. In this way, the electric energy converted by the photovoltaic panel 30 can be transmitted to the interface 50 through the first electrical connector 61 by using the first electrical connector 61, and then transmitted to the energy storage device or electrical equipment by the interface 50. Optionally, the first electrical connector 61 includes but is not limited to a wire.

[0069] Please refer to Figures 10-11 again. In this embodiment, there are multiple cover plate assemblies 1, and the multiple cover plate assemblies 1 are rotated and connected in sequence along a preset direction. The interfaces 50 of the multiple cover plate assemblies 1 are also arranged along the preset direction. The interface 50 includes a positive sub-interface 51 and a negative sub-interface 52. When the multiple cover plate assemblies 1 are flattened, the positive sub-interface 51 of each interface 50 corresponds to the positive sub-interface 51 of other interfaces 50, and the negative sub-interface 52 of each interface 50 corresponds to the negative sub-interface 52 of other interfaces 50.

[0070] There can be multiple cover panel assemblies 1. This embodiment uses only three cover panel assemblies 1 for schematic illustration. Each cover panel assembly 1 is rectangular, and the three cover panel assemblies 1 are arranged sequentially along the width of the rectangle. Adjacent cover panel assemblies 1 are pivotally connected. Specifically, the first cover panel assembly 1 pivotally connects to one end of the second cover panel assembly 1, and the other end of the second cover panel assembly 1 pivotally connects to the third cover panel assembly 1. The three cover panel assemblies 1 can be folded twice, thereby changing the overall size of the cover panel assembly 1.

[0071] Each cover plate assembly 1 is provided with a first electrical connector 61 and an interface 50. In this embodiment, the three interfaces 50 are also arranged along a preset direction, i.e., the width direction. Each interface 50 includes a positive sub-interface 51 and a negative sub-interface 52. In this embodiment, when the multiple cover plate assemblies 1 are flattened, the positive sub-interface 51 of each interface 50 corresponds to the positive sub-interface 51 of the other interfaces 50, and the negative sub-interface 52 of each interface 50 corresponds to the negative sub-interface 52 of the other interfaces 50. In other words, the positive sub-interface 51 corresponds to the positive sub-interface 51, and the negative sub-interface 52 corresponds to the negative sub-interface 52. This facilitates the connection of subsequent electrical connectors.

[0072] Referring again to Figure 11, in this embodiment, the cover assembly 1 further includes at least one second electrical connector 62 and at least one third electrical connector 63. The opposite ends of each second electrical connector 62 are electrically connected to the positive sub-interfaces 51 of two adjacent interfaces 50; and the opposite ends of each third electrical connector 63 are electrically connected to the negative sub-interfaces 52 of two adjacent interfaces 50. The second and third electrical connectors 62, 63 are detachably connected to the interfaces 50, and / or the lengths of the second and third electrical connectors 62, 63 can be extended and restored to their original state.

[0073] The cover plate assembly 1 may also include a second electrical connector 62 and a third electrical connector 63, wherein the second electrical connector 62 is used to electrically connect the positive sub-interface 51 of two adjacent interfaces 50, and the third electrical connector 63 is used to electrically connect the negative sub-interface 52 of two adjacent interfaces 50, thereby connecting the positive sub-interface 51 and the negative sub-interface 52 of multiple cover plate assemblies 1 together, which can simplify the layout of the electrical connectors and facilitate subsequent electrical connection to the energy storage device or electrical equipment.

[0074] Furthermore, because the cover assembly 1 rotates relative to each other and folds twice, in one embodiment, the second electrical connector 62 and the third electrical connector 63 can be detachably connected to the interface 50. That is, the second electrical connector 62 and the third electrical connector 63 are removed from the interface 50 during folding and then reassembled to the interface 50 during flattening, thereby preventing the second electrical connector 62 and the third electrical connector 63 from interfering with the folding of the cover assembly 1. In another embodiment, the length of the second electrical connector 62 and the third electrical connector 63 is variable, extending during folding and returning to its original length when flattened, thereby not interfering with the folding of the cover assembly 1. Optionally, the second electrical connector 62 and the third electrical connector 63 include, but are not limited to, threads.

[0075] It should be noted that this embodiment may satisfy only one embodiment or another embodiment, or may satisfy both one embodiment and another embodiment.

Figure 17 is a schematic diagram of a partial cross-section of the foldable cover shown in Figure 13. This embodiment provides a foldable cover 2 for being mounted on a trunk 82 of a mobile device 3 to cover the opening of the trunk 82. The foldable cover 2 includes a plurality of rotatably connected cover assemblies 1 as provided in the above embodiments of the present application, and a profile 70. The cover assembly 1 can be rotatably folded onto the remaining cover assemblies 1 to reveal the opening. The profile 70 has a receiving groove 71, and the periphery of the cover assembly 1 is bonded to the groove wall of the receiving groove 71.

[0077] The mobile device 3 includes but is not limited to vehicles with an open trunk 82, such as pickup trucks, trucks, box trucks, and snowmobiles. The foldable cover 2 can be installed on the side of the trunk 82 so that when the foldable cover 2 is flattened, it can cover the opening of the trunk 82, thereby effectively protecting the items in the trunk 82. The foldable cover 2 includes a plurality of cover assemblies 1 provided in the above-mentioned embodiment that are connected in sequence and rotated, and a profile 70. When the cover assembly 1 is folded to other cover assemblies 1, the opening can be opened to different degrees, and the user can fold it according to needs. For example, in this embodiment, the foldable cover 2 is schematically illustrated as including three cover assemblies 1. The cover assembly 1 located at the rear of the trunk 82 can be rotated and overlapped on the cover assembly 1 located in the middle to reveal the opening part of the trunk 82 for easy placement of items. Furthermore, the middle cover assembly 1 can be rotated again so that the middle cover assembly 1 and the cover assembly 1 at the rear of the trunk 82 can be overlapped together to the cover assembly 1 near the cab 81, thereby revealing a larger area of ​​the trunk 82 opening, which is convenient for taking and placing larger items. The profile 70 also has a receiving groove 71 for accommodating the periphery of the cover assembly 1. In other words, the periphery of the cover assembly 1 can be bonded to the groove wall of the receiving groove 71 with a sealant and then secured with screw fasteners. Optionally, hot melt welding and riveting can be used during installation.

[0078] Optionally, an energy storage device is provided within the trunk 82. The energy storage device is electrically connected to the photovoltaic panel 30 of the cover assembly 1 within the foldable cover 2, and transmits the electrical energy converted by the photovoltaic panel 30 to the energy storage device for backup. Alternatively, the photovoltaic panel 30 may be directly electrically connected to electrical devices within the mobile device 3 or to a battery within the mobile device 3 to provide electrical energy or charge the device.

[0079] The foldable cover 2 provided in this embodiment, by adopting the cover assembly 1 provided in the above embodiment of this application, can not only cover the opening of the trunk 82, but also utilize the photovoltaic panel 30 in the cover assembly 1 to convert light energy into electrical energy, thereby providing electrical energy for the mobile device 3.

[0080] In this embodiment, the periphery of the cover plate 10 of the cover plate assembly 1 is positioned within the receiving groove 71, while the photovoltaic panel 30 of the cover plate assembly 1 is positioned outside the receiving groove 71. While the periphery of the cover plate assembly 1 is positioned within the receiving groove 71, this embodiment allows the photovoltaic panel 30 of the cover plate assembly 1 to be positioned outside the receiving groove 71. In other words, the photovoltaic panel 30 is not positioned at the periphery of the cover plate 10. This not only increases the utilization rate of the photovoltaic panel 30 but also effectively protects the photovoltaic panel 30 from damage.

[0081] In this embodiment, when the cover assembly 1 is folded, the profile 70 of one cover assembly 1 is pressed onto the profile 70 of another cover assembly 1, preventing the photovoltaic panel 30 of the cover assembly 1 from being crushed by the profile 70, thereby effectively protecting the photovoltaic panel 30.
