[0041] Reference Figure 1 In one embodiment of the present application, a vehicle cover power generation device is provided. The vehicle cover power generation device includes a cover body 100. The cover body 100 has a roof area 101, a body area 102, and a bottom area 103. The body area 102 is connected between the roof area 101 and the bottom area 103. The roof area 101, the body area 102, and the bottom area 103 are defined as the corresponding parts when the cover body 100 is used to cover the vehicle 200. Exemplarily, the cover body 100 can be used to cover a new energy vehicle, so that the electric energy generated by the cover body 100 can be connected to the new energy vehicle for use, thereby facilitating the improvement of the storage capacity of the new energy vehicle, thereby facilitating the improvement of the endurance of the vehicle 200.

[0042] Combined with reference Figure 1 , Figures 2 to 4The cover 100 includes a heat absorption layer 10, a thermoelectric power generation layer 20, a cooling layer 30 and a heat dissipation layer 40. The heat absorption layer 10 is arranged in the roof area 101 and the body area 102, so as to absorb the heat energy of solar radiation. The thermoelectric power generation layer 20 is attached to the end of the heat absorption layer 10 in the roof area 101 away from the cover of the cover 100. The cooling layer 30 is attached to the end of the thermoelectric power generation layer 20 away from the cover of the cover 100. The cooling layer 30 is also attached to the end of the heat absorption layer 10 in the body area 102 away from the cover of the cover 100. The cooling layer 30 is also arranged in the bottom area 103. The heat dissipation layer 40 is attached to the end of the cooling layer in the bottom area 103 close to the cover of the cover 100, so as to dissipate the heat conducted by the cooling layer 30 to the outside of the cover away from the vehicle 200, thereby accelerating the heat conduction efficiency. The heat dissipation layer 40 cooperates with the cooling layer 30 to increase the temperature difference between the two ends of the thermoelectric power generation layer 20, thereby improving the power generation efficiency, and can dissipate the heat of the heat absorption layer 10 outside the cover, thereby also improving the heat insulation protection of the cover body 100. The area of ​​the cover body 100 close to the vehicle 200 during use is defined as the inside of the cover, and the area away from the vehicle 200 and facing the sun is defined as the outside of the cover.

[0043] In the present application, a heat absorption layer 10, a thermoelectric power generation layer 20, a cooling layer 30 and a heat dissipation layer 40 are arranged in different areas of the cover body 100, so that in the roof area 101, the heat absorption layer 10, the thermoelectric power generation layer 20 and the cooling layer 30 together form a thermoelectric battery, which can absorb the heat provided by solar energy to generate electricity, so that the car cover can provide electrical energy, and the heat dissipation layer 40 arranged in the bottom area 103 of the vehicle cooperates with the cooling layer 30 in each area to dissipate heat to the outside of the car cover, so as to increase the temperature difference on both sides of the thermoelectric power generation layer 20, thereby facilitating the improvement of the heat insulation protection and power generation efficiency of the cover body 100. Therefore, the car cover power generation device of the present application has both the functions of heat insulation and power generation, which is conducive to improving the utilization rate.

[0044] In some embodiments, reference Figure 2 and Figure 3The heat absorption layer 10 includes a heat absorption coating 11 and a first flexible heat conductive layer 12. For example, the heat absorption coating 11 may include a binder and a metal compound additive. For example, the binder includes one of acrylic acid, silicon or polyurethane, and the metal compound additive includes at least one of copper oxide, manganese dioxide, cobalt oxide, chromium oxide, iron oxide, lead sulfide or nickel sulfide. The heat absorption coating 11 is arranged at one end of the first flexible heat conductive layer 12 close to the cover 100. The thermoelectric power generation layer 20 and the cooling layer 30 of the vehicle body area 102 are both attached to the end of the first flexible heat conductive layer 12 away from the heat absorption coating 11, so that the heat absorption coating 11 conducts the absorbed solar heat to the first flexible heat conductive layer 12, and the first flexible heat conductive layer 12 then conducts the heat to the corresponding thermoelectric power generation layer 20 and the cooling layer 30. For example, the first flexible heat conductive layer 12 can be a graphene textile or a soft silicone layer. The structure of the heat absorption layer 10 is conducive to improving the heat absorption and heat conduction efficiency.

[0045] In some embodiments, in conjunction with reference Figure 2 The thermoelectric power generation layer 20 includes a plurality of thermoelectric power generation sheets 21, and the plurality of thermoelectric power generation sheets 21 are arranged in series. For example, the plurality of thermoelectric power generation sheets 21 can be connected in series by copper wires. The plurality of thermoelectric power generation sheets 21 connected in series to form a power generation device is conducive to ensuring power generation efficiency while making the thermoelectric power generation layer 20 deformable, thereby facilitating the storage of the cover body 100.

[0046] In another embodiment, power generation can be performed by a single thermoelectric power generation sheet 21 .

[0047] In some embodiments, in conjunction with reference Figures 2 to 4 The cooling layer 30 includes a coolant hose line 32 and a second flexible heat-conducting layer 31 which are bonded to each other. The coolant hose line 32 is arranged on the side of the second flexible heat-conducting layer 31 away from the cover outside the cover body 100. In the roof area 101, the coolant hose line 32 is oriented and laid along the series route of multiple thermoelectric power generation sheets 21, and the second flexible heat-conducting layer 31 is attached to the thermoelectric power generation layer 20, the heat absorption layer 10 of the body area 102, and the heat dissipation layer 40. In this embodiment, the second flexible heat-conducting layer 31 is attached to the thermoelectric power generation layer 20, the first flexible heat-conducting layer 12 of the heat absorption layer 10 of the body area 102, and the heat dissipation layer 40. Exemplarily, the second flexible heat-conducting layer 31 can be a graphene textile or a soft silicone layer. The flexible heat-conducting layer can achieve a bonding connection between different layers by hot pressing. The structure of the cooling layer 30 is conducive to improving the thermal conductivity efficiency to improve the cooling effect on the one hand, and is convenient for the cover body 100 to be stored on the other hand.

[0048] In some embodiments, the coolant hose 32 includes a flat flexible water pipe 321 and a coolant bag. In the roof area 101, the flat flexible water pipe 321 is laid along the series route of multiple temperature difference power generation sheets 21. Exemplarily, the flat flexible water pipe 321 can be a plastic hose. The coolant bag is disposed in the flat flexible water pipe 321. The coolant bag includes a bag body and a coolant disposed in the bag body. Exemplarily, the bag body can be a plastic bag, and the coolant can include water or glycerin. The flat flexible water pipe 321 is conducive to further reducing the storage volume of the cover body 100, and the coolant bag facilitates the disassembly and assembly of the coolant hose. Exemplarily, the cross-sectional shape of the flat flexible water pipe 321 can be an elliptical shape or a square structure with semicircular arcs at both ends (refer to Figure 5 ).

[0049] In some embodiments, in conjunction with reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The cover body 100 is provided with a first opening 104 and a second opening 105, the first opening 104 is located in the roof area 101, and an open end of the flat flexible water pipe 321 is arranged in the first opening 104.

The cooling liquid package can be cooled in the refrigerator and then loaded into the flat flexible water pipe 321 for use, which is convenient for improving the cooling efficiency of the cooling layer 30, thereby facilitating improving the power generation efficiency.

[0050] It is understandable that openable or closable covers may be installed at the edges of both the first opening 104 and the second opening 105 to prevent the coolant bag from escaping from the first opening 104 or the second opening 105 during use.

[0051] In some embodiments, reference Figures 2 to 4 The cooling layer 30 further includes a first thermally conductive adhesive layer 33, which is bonded between the coolant hose line 32 and the second flexible thermally conductive layer 31.

Exemplarily, the material of the first thermally conductive adhesive layer 33 can be a silicone-type thermally conductive adhesive, a silica-type thermally conductive adhesive, a polyimide-type thermally conductive adhesive, or an epoxy-type thermally conductive adhesive.

[0052] In some embodiments, reference Figure 4 and Figure 6The heat dissipation layer 40 includes a plurality of heat sinks 41 and a second thermally conductive adhesive layer 42. The plurality of heat sinks 41 are arranged in a row, and there is a gap between two adjacent heat sinks 41.

The structure of the heat dissipation layer 40 is conducive to further improving the heat dissipation effect.

[0053] In some embodiments, reference Figure 1 as well as Figures 2 to 4 , the cover 100 also includes a flexible insulation layer 50. Exemplarily, the flexible insulation layer 50 can be a kind of aerogel felt material or a flexible graphene insulation material. The flexible insulation layer 50 is attached to one end of the cooling layer 30 in the roof area 101 close to the cover of the cover 100. In this embodiment, the flexible insulation layer 50 is attached to one end of the cooling layer 30 in the roof area 101 close to the coolant hose line 32. The flexible insulation layer 50 is also attached to one end of the cooling layer 30 in the bottom area 103 close to the cover of the cover 100. In this embodiment, the flexible insulation layer 50 is also attached to one side of the cooling layer 30 in the bottom area 103 close to the coolant hose line 32. The flexible insulation layer 50 is conducive to further improving the heat insulation of the cover 100, and is also conducive to reducing the damage to the surface of the vehicle 200 when the cover 100 is used.

[0054] In some embodiments, the flexible heat insulating layer 50 is also attached to an end of the cooling layer 30 in the vehicle body region 102 close to the inner side of the cover body 100 , thereby facilitating further improvement of heat insulating properties and protection.

Exemplarily, the inverter 300 and the anti-backflow device 400 can be arranged outside the cover of the cover body 100. Exemplarily, the anti-backflow device 400 can include an anti-backflow meter or an anti-backflow sensor. Exemplarily, the positive and negative electrodes of the temperature difference power generation layer 20 can correspond to the positive and negative electrodes of the input end of the inverter 300, and the output end of the inverter 300 can be connected in series with the anti-backflow device 400. When the anti-backflow device 400 detects the reverse current, it can transmit a signal to the inverter 300, so that the inverter 300 can adjust the output frequency.
