[0002] The present invention relates to an interior arrangement in the field of vehicle interiors. BACKGROUND

[0003] In the current vehicle market, with the continuous growth of consumer demand and the increasing specialization of consumer groups, more and more users expect that the details of each part of the vehicle can reflect the excellent quality, and the vehicle is no longer just a simple means of transportation, but has become a place that can bring people comfort and coziness.

[0004] A vehicle interior system is a critical component of a vehicle. Vehicle interiors have significant value and significance, as passengers can most directly experience the atmosphere within vehicles from the interior spaces. To meet the diverse needs of passengers, interior components have become increasingly functional.

[0005] In clear weather, it's not uncommon for sunlight to hit the cab for extended periods, resulting in significant heat buildup inside the cab, even if the front of the vehicle is equipped with a windshield that still doesn't effectively dissipate heat. In addition, the reflected light produced by sunlight after hitting the trim panels can also potentially obstruct the driver's line of sight, thus posing safety risks. There is currently no effective solution available in the state of the art. SUMMARY OF THE INVENTION

[0006] It should be noted that an object of the present invention is to overcome one or more deficiencies found in the prior art, namely to provide an interior assembly. The interior assembly includes a trim part having an upper surface and a lower surface.The casing part includes graphene, and the lower surface of the casing part is provided or integrated with a semiconductor cooling plate to absorb heat from the lower surface of the casing part; when a temperature of the upper surface of the casing part increases, a temperature difference between the upper and lower surfaces of the casing part can enable the graphene to generate electrical energy; and after the electrical energy between the upper and lower surfaces of the casing part is provided to the semiconductor cooling plate, the semiconductor cooling plate can reduce the temperature of the casing part.

[0007] The interior assembly according to the present invention can effectively reduce heat in a driver's cab. The semiconductor cooling plate power can provide power when the vehicle engine is off and no power is supplied, and can also generate a thermoelectric effect when power is supplied, thereby reducing the temperature of the trim panel surface, resulting in a reduction in the temperature in the driver's cab.

[0008] Furthermore, the graphene arranged on the trim part can dissipate heat, thereby reducing the effects of light reflection and the temperature in the cab.

[0009] In various embodiments of the method according to the present invention, it may rely on one and / or more of the following configurations, either alone or in combination:

[0010] In one embodiment, a raw material of the trim part is premixed with the graphene before production.

[0011] Optionally, the upper and lower surfaces of the fairing part are each coated with at least one layer of graphene film.

[0012] Preferably, the at least one layer of graphene film (11) is 1 µm to 100 µm thick.

[0013] In one embodiment, the semiconductor cooling plate includes a P-type semiconductor and an N-type semiconductor, wherein the P-type semiconductor is Bi2Te3-Sb2Te3 and the N-type semiconductor is Bi2Te3-Bi2Se3.

The energy conversion device includes a photovoltaic cell module and a waveguide, and the photovoltaic cell module is installed on at least one side of the waveguide. The waveguide, which is a sheet-like optical structure, has a length and width that are much greater than their thickness.

[0015] In one embodiment, a substrate of the waveguide is made of a transparent material PC or PMMA.

[0016] In one embodiment, the waveguide is doped with quantum dots to absorb various wavelengths of the spectrum. The quantum dots, also called light-absorbing nanoparticles or colloidal quantum dots, absorb a certain portion of the solar flux and re-emit that portion as photoluminescence at longer wavelengths.

[0017] The size of the quantum dots can be adjusted to absorb different wavelengths of the spectrum (e.g., infrared light or visible light; additionally, a multilayer waveguide can be used to absorb more of the spectrum), thereby releasing heat electrons to generate electromotive force.

[0018] Optionally, the waveguide is equipped with light-emitting dopants, such as styrene and phosphorescent dopants.

[0019] Preferably, the thickness of the waveguide is between 1 mm and 4 mm.

[0020] In one embodiment, at least one layer of fluorescent ink is printed on a surface of the waveguide.

[0021] The fluorescent ink can absorb radiation of a specific wavelength or waveband and emit radiation of a different wavelength or waveband. Specifically, the fluorescent ink can be printed onto the waveguide to absorb sunlight, allowing a photovoltaic cell module to absorb wavelength fluorescence. Fluorescence that meets a specific condition can be transmitted over a long distance in the waveguide.

[0022] In one embodiment, the energy conversion device further includes a mirror reflector that is metallized on at least one side of the waveguide.

[0023] For example, mirror reflectors are arranged on two adjacent sides of the waveguide, and photovoltaic cell modules are arranged on the other two opposite adjacent sides of the waveguide. Alternatively, mirror reflectors are arranged on one to three of the four sides of the waveguide, and photovoltaic cell modules are arranged on the remaining sides.

[0024] Preferably, the mirror reflector is arranged on one side of the waveguide relative to the photovoltaic cell module.

[0026] Optionally, a selective reflecting layer is arranged on the surface of the waveguide, the mirror reflector (such as the bottom of the waveguide in Fig. 4) can also be arranged on a non-sunlight incident surface, and the selective reflective layer is a photonic crystal or an optical high-reflection coating.

[0027] The energy conversion device in the indoor array according to the present invention allows sunlight collected by a large-area waveguide to be concentrated on the photovoltaic cell modules arranged on the small-area sides, allowing solar energy to be effectively converted from sunlight. Furthermore, the photovoltaic cell modules do not need to be arranged in a large area, thus providing a significant cost advantage. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It should be understood that the above accompanying drawings do not represent true proportions, but are merely simple drawings used to illustrate a variety of preferred features of the basic principles of the present invention. The design features disclosed in the present invention, such as size, orientation, positioning, and shape, are determined according to the specific application and usage environment.

[0031] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings. In these accompanying drawings, the same reference numerals refer to the same or similar elements of the present invention throughout the drawings.

[0032] Fig. 1 is a cross-sectional view of an interior assembly according to an embodiment of the present invention. The interior assembly includes a trim panel 1 having an upper surface and a lower surface. The trim panel 1 includes graphene, and the lower surface of the trim panel 1 is provided or integrated with a semiconductor cooling plate 2.

[0033] In particular, a raw material of the trim part 1 is premixed with the graphene and then manufactured so that the finished trim part 1 has the properties of the graphene.

[0034] Referring to Fig. 2 is Fig. Figure 2 shows a cross-sectional view of an interior assembly according to another embodiment of the present invention. The upper and lower surfaces of the trim part 1 are each coated with at least one layer of graphene film 11.

[0035] The thickness of each layer of graphene film 11 can be changed between 1 µm and 100 µm according to specific conditions, and the shape of each layer of graphene film can be designed according to the actual area of ​​the panel part 1.

[0036] Since the graphene has very good heat conduction performance and also very good optical properties, when the covering part 1 is provided with the graphene, the illumination reflection problem caused by sunlight can be effectively reduced and heat caused by solar radiation can be dissipated.

[0037] The semiconductor cooling plate 2 can absorb heat from the graphene film 11 on the lower surface of the casing part 1. Preferably, the semiconductor cooling plate 2 includes a P-type semiconductor and an N-type semiconductor. The P-type semiconductor is made of Bi2Te3-Sb2Te3. The N-type semiconductor is made of Bi2Te3-Bi2Se3. Therefore, the internal arrangement has the advantages of long service life, environmental friendliness, and high efficiency.

[0038] When a vehicle's engine is turned off, the upper surface of the trim panel 1 becomes very hot due to solar radiation. Over time, the temperature of the upper surface of the trim panel 1 continuously rises. Due to the properties of graphene and the semiconductor cooling plate 2, the temperature difference between the upper and lower surfaces of the trim panel 1 generates electrical energy, which can be stored or utilized by the semiconductor cooling plate 2.

[0039] When the engine of the vehicle is turned on, the electric energy is provided to the semiconductor cooling plate 2, and the temperature of the upper surface of the trim part 1 will be reduced by the thermoelectric effect, so that the temperature of a cab of the vehicle is lowered in an active mode.

[0040] The graphene and the semiconductor cooling plate 2 are arranged on the trim part 1 to effectively reduce the influence of solar radiation on a user in the vehicle's cab and lower the temperature in the cab. Therefore, the comfort level of the vehicle's user is improved.

[0041] Referring to Fig. 3 is Fig. 3 is a schematic representation of an interior assembly located in a driver's cab of a vehicle according to an embodiment of the present invention. The interior assembly further includes an energy conversion device located on the upper surface of the trim part 1.

[0042] Fig. Figure 4 is a schematic diagram of an indoor power conversion device according to an embodiment of the present invention. The power conversion device includes a photovoltaic cell module 4 and a waveguide 3, and the photovoltaic cell module 4 is arranged on at least one side of the waveguide 3.

[0043] Generally, the waveguide 3, which is a sheet-like optical structure, has a length and width that is much greater than its thickness. Preferably, the thickness of the waveguide 3 can be varied between 1 mm and 4 mm, and the specific thickness is adjusted according to the solar irradiation area.

[0044] A substrate of the waveguide 3 is a transparent material, and optionally made of PC or PMMA.

[0045] The waveguide 3 can be equipped with light-emitting dopants, such as styrene and phosphorescent dopants.

[0046] Preferably, the waveguide 3 can be doped with specific quantum dots (also called light-absorbing nanoparticles or colloidal quantum dots) to absorb a certain part of the solar flux and re-emit this part as photoluminescence with longer wavelengths.

[0047] The size of the quantum dots can be adjusted to absorb different wavelengths of the spectrum, such as infrared or visible light. Additionally, a multilayer waveguide 3 can be used to absorb more of the spectrum, releasing heat electrons to generate electromotive force.

[0048] Preferably, at least one layer of fluorescent ink is printed on a surface of the waveguide 3.

[0049] The fluorescent ink can absorb radiation of a specific wavelength or waveband and emit radiation of a different wavelength or waveband. Specifically, the fluorescent ink can be printed onto the waveguide 3 to absorb sunlight, and then the photovoltaic cell module 4 can absorb wavelength fluorescence. Fluorescence that meets a specific condition can be transmitted over a long distance in the waveguide 3.

[0050] With particular reference to Fig. 4 According to one embodiment of the invention, the waveguide 3 is a parallelogram. Optionally, the photovoltaic cell modules 4 are arranged on the four sides of the waveguide 3 to form a coupling optical path.

[0051] The energy conversion device further includes a mirror reflector 5, which is metallized on at least one side of the waveguide 3. One material of the mirror reflector 5 is aluminum, silver, or indium.

[0052] Preferably, the mirror reflector 5 is arranged on one side of the waveguide 3 relative to the photovoltaic cell module 4, for example, mirror reflectors 5 are arranged on the two adjacent sides of the waveguide 3, and the photovoltaic cell modules 4 are arranged on the other two opposite adjacent sides of the waveguide 3. Alternatively, the mirror reflectors 5 are arranged on one side of the waveguide 3, and the photovoltaic cell modules 4 (namely in the Fig. 4) are arranged on the other side, opposite thereto, of the waveguide 3. Alternatively, the mirror reflectors 5 are arranged on one to three of the four sides of the waveguide 3, and the photovoltaic cell modules 4 are then arranged on the remaining sides.

[0053] In addition, a selective reflecting layer is arranged on the surface of the waveguide 3. The mirror reflector 5 (such as the bottom of the waveguide 3 in Fig. 4) can also be arranged on a non-sunlit surface. The selective reflective layer is a photonic crystal or a high-reflection optical coating.

[0054] The process by which the energy conversion device absorbs sunlight and then converts solar energy into electrical energy is described in detail.

[0055] When sunlight irradiates the surface of the waveguide 3 from the upper portion of the energy conversion device, the fluorescent ink on the waveguide 3 can absorb sunlight and emit fluorescence, and the generated fluorescence can be evenly distributed in all directions.

[0056] The fluorescence can undergo a series of emission and refraction at the interface between the transparent substrate of the waveguide 3 and the fluorescent ink to reach the upper and lower surfaces of the waveguide 3. When the fluorescence is within the total reflection angle determined by the refractive index of the transparent substrate and the refractive index of the fluorescent ink, the fluorescence can undergo total reflection at the upper and lower surfaces of the waveguide 3 to be returned to the waveguide 3. Therefore, the fluorescence is transmitted to the sides of the waveguide 3 in the waveguide 3 through successive reflection and refraction until reaching the four sides of the waveguide 3 to be emitted outward. Then, the fluorescence is coupled into the photovoltaic cell module 4 and converted into electrical energy to be output.

[0057] The energy conversion device can concentrate the sunlight collected by a large-area waveguide 3 onto the photovoltaic cell modules 4 arranged on a small-area side, so that the photovoltaic cell module 4 with a small area can receive the light, achieving a large equivalent light condensation effect. Since the cost of the waveguide 3 is far lower than that of the photovoltaic cell modules 4, the usage amount of the photovoltaic cell modules 4 is reduced, i.e., the cost of energy conversion is reduced.

[0058] Therefore, the energy conversion device in the indoor assembly according to the present invention can effectively convert solar energy from sunlight. Furthermore, the photovoltaic cell modules 4 do not need to be arranged over a large area, thus the indoor assembly offers a significant cost advantage.

[0059] Optionally, the waveguide 3 can be configured in any polygonal shape, such as a triangle or a wedge, according to specific requirements. The photovoltaic cell modules 4 arranged along the short side of the waveguide 3 can also achieve the same effect.

[0060] In addition, the interior arrangement according to the present invention is well integrated into the vehicle, easy to assemble and free from high installation costs.

[0061] The above embodiments are merely examples and do not limit the scope of the present invention. Based on this, one skilled in the art can devise other embodiments capable of achieving the same function within the scope of the claims of the present invention.

[0062] The person skilled in the art has / has a multitude of embodiments and a multitude of modifications and improvements. In particular, it should be noted that, except in cases of obvious contradictions or incompatibilities, the above-mentioned features, modification modes, and / or specific embodiments of the present invention may be combined with one another. All of these embodiments, modifications, and improvements are within the scope of the present invention. QUOTES CONTAINED IN THE DESCRIPTION
