Description

[Technical Field]

[0001] The present invention relates to a wireless light for an automobile interior. [Background technology]

[0002] In recent years, not only comfort and safety but also visual aesthetics and other design aspects have become important in automobile interiors. In addition to the interior design of automobiles, users may also customize their automobile interiors by adding their own decorations. One example of this is the installation of interior lighting, which involves obtaining power from a power supply such as a cigarette lighter socket, extending an electric wire to the desired position of the interior lighting, and connecting the wire to the interior of the vehicle using a connecting means such as double-sided tape, allowing the user to enjoy the interior of the vehicle.

[0003] Furthermore, the LED lighting device described in Patent Document 1 includes, for example, an LED element mounted on a substrate, a transparent covering covering the light-emitting surface of the LED element, and a light guide that introduces light emitted from the light-emitting surface of the LED element through a light-introducing end and functions as a light transmission path, and the light guide is mounted on the substrate together with the covering using a transparent resin material. The LED lighting device is flexible and elongated, allowing it to be positioned to follow the shape of the object to which it is attached, thereby increasing the degree of freedom in placement.

[0005] However, since the lighting in a car interior is fixed, there is a problem that the position of the lighting cannot be easily changed. Also, the LED lighting device described above requires wiring from the power supply unit to the lighting device, which not only limits the placement of the lighting device but also impairs the aesthetics of the car interior because the wiring is noticeable. [Means for solving the problem]

[0006] The present invention has been made in consideration of the above-mentioned problems, and the wireless light for automobile interiors of the present invention is a wireless light for automobile interiors in which an illumination component is placed on the interior of the vehicle, wherein the interior of the vehicle comprises at least a wireless power supply coil, a cover material, and a vehicle interior side connection component, and the illumination component comprises at least a lighting side connection component, a receiving coil, and a lighting component, and the vehicle interior side connection component and the lighting side connection component are connected to each other. [Effects of the Invention]

[0007] The wireless light for automotive interiors of the present invention can be illuminated anywhere in the vehicle interior where a wireless power transfer coil is installed. In other words, any part of the vehicle interior where a wireless power transfer coil is installed can be illuminated, which is effective for arranging the interior to change the mood without compromising the design. [Brief explanation of the drawings]

[0008] [Figure 1] 1 is a view showing a first embodiment of a wireless light for automobile interior use according to the present invention, illustrating a door trim on which the wireless light for automobile interior use is installed, viewed from the inside of the vehicle. [Figure 2] 2 is a view of the door trim of the first embodiment of the wireless light for automobile interior use in FIG. 1, seen from inside the vehicle, before the lighting member is installed in the vehicle interior portion. FIG. [Figure 3] 2 is a cross-sectional view showing the first embodiment of the wireless light for automobile interior use in FIG. 1 in a cut state. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] [Implementation] The wireless light for automobile interiors of the present invention will be explained below with reference to FIG. As shown in FIG. 1, the wireless light 1 for automobile interiors has an illumination member 4 arranged on an interior portion 3 of the automobile.

[0010] The installation location of the wireless light 1 for automobile interior use according to the present invention is not particularly limited as long as it is a location where the vehicle interior part 3 including the wireless power supply coil 2 to be supplied with power can be installed. Examples of locations where the vehicle interior part 3 can be installed include the door trim, ceiling, floor, seat, dashboard, etc., which will be described later. In the embodiment of the present invention, installation on the door trim is shown.

[0011] The wireless power supply coil 2 of the present invention is not particularly limited as long as it is equipped with a power supply coil for supplying power onto a substrate such as a film or sheet, but when the power receiving coil 6 provided in the lighting member 4 and the wireless power supply coil 2 in the vehicle interior part 3 are brought into close proximity, magnetic field resonance occurs, and power is supplied from the wireless power supply coil 2 to the power receiving coil 6 in a contactless manner, i.e., power is supplied to the lighting member 4, causing it to emit light. Furthermore, while the wireless power transfer coil 2 would be conspicuous if it were placed inside a vehicle interior, a thick one made of conventional copper wire can be made thin by using, for example, an electroless plating method using polypyrrole, known as the "PPy plating method," which makes it less conspicuous even when placed inside a vehicle interior, which is more preferable. Specifically, the thickness of the wireless power transfer coil 2 is preferably 1 mm or less. With this thickness, the surface irregularities can be minimized when placed inside a vehicle interior, thereby preventing the aesthetic appearance of the vehicle interior from being marred.

[0012] The vehicle interior portion 3 of the present invention includes at least the wireless power supply coil 2, the cover material 5, and the vehicle interior portion side connection portion 7. The location where the vehicle interior part 3 is installed is not particularly limited as long as it is a location that catches the user's eye, such as the door trim, ceiling, floor, seat, or dashboard. The cover material 5 may be made of natural leather, synthetic leather, or fabric such as knitted or woven fabric, and it is preferable to use synthetic leather because of its excellent feel, appearance, cost, and the like.

[0013] The vehicle interior side connecting portion 7 is connected to a lighting side connecting portion 8, which will be described later, to arrange the lighting member 4 on the vehicle interior side portion 3. In this specification, "connection" refers to a state in which at least two components are joined or fixed together, so that the components maintain a predetermined positional relationship and function as a single unit. The form of connection is not limited, and includes, for example, magnetic attraction, attachment with hook-and-loop fasteners, or fixation by other physical means. In other words, "connecting the vehicle interior connection part 7 and the lighting connection part 8" refers to placing the lighting member 4 on the vehicle interior part 3 by overlapping the vehicle interior connection part 7 and the lighting connection part 8, and maintaining this position causes the lighting member 4 to be powered and emit light. Since it is desirable for the lighting member 4 to be detachable from the vehicle interior portion 3 when the user arranges the interior, the vehicle interior connection portion 7 and the lighting connection portion 8 must be the same member, and must be able to be connected and detached from each other. In an embodiment of the present invention, magnets are used. By using magnets for the vehicle interior connection portion 7 and the lighting connection portion 8, connection and detachment are facilitated, making it easier for the user to align the lighting member 4 when placing it on the vehicle interior portion 3. 2, the vehicle interior side connection parts 7 may be provided at specific locations in the vehicle interior section 3 where the lighting members 4 may be installed, or may be provided over a wide area of the vehicle interior, although this is not shown. By providing the vehicle interior side connection parts 7 over a wide area of the vehicle interior, the user can fine-tune the location where the lighting members 4 are installed, allowing the user to enjoy the vehicle interior even more.

[0014] The lighting member 4 of the present invention is composed of at least a lighting-side connection part 8, a power receiving coil 6, and a lighting part 9, and connects the lighting-side connection part 8 to the vehicle interior-side connection part 6 in the vehicle interior part 3. Details of the lighting-side connection part 8 will be omitted because it uses the same material as the vehicle interior-side connection part 6. The lighting unit 9 is connected to the power receiving coil 6, and emits light when power is supplied contactlessly from the wireless power transfer coil 2 to the power receiving coil 6. To enjoy the interior of the car, it is desirable that the lighting unit 9 be small and lightweight, have a degree of freedom in color, and be capable of dimming and control. From the above perspective, an LED (light emitting diode) is preferable.

[0015] In an embodiment of the present invention, as shown in Fig. 3, it is desirable that the wireless power transfer coil 2 and the power receiving coil 6 are provided via the vehicle interior part 3, the cover material 5, and the vehicle interior side connection part 7, but the present invention is not limited to this. For example, in terms of the stacking order, if the vehicle interior side connection part 7 is a magnet, the cover material 5 may be provided on top of the vehicle interior side connection part 7. With this configuration, the installation position of the lighting member 4 becomes less noticeable, allowing the vehicle interior to be more enjoyable. Furthermore, even if the vehicle interior part 3 is thick, for example, if multiple layers of cover material 5 are stacked in the vehicle interior part 3, the wireless light for automotive interior of the present invention can emit light. As described above, the power receiving coil 6 and the wireless power transfer coil 2 do not need to be in close proximity to each other because magnetic field resonance occurs when the two coils are in close proximity and power is supplied. However, if the power receiving coil 6 and the wireless power transfer coil 2 are too far apart in the vertical direction, the power supply may be weak and the light emission may be weak, so the distance between the power receiving coil 6 and the wireless power transfer coil 2 is preferably within 5 cm. On the other hand, since magnetic field resonance weakens with increasing horizontal distance, it is desirable to place the lighting member 4 including the lighting side connection part 8 via the cover material 5 and the vehicle interior side connection part 7 at a vertical position of the wireless power supply coil 2.
