Description

Technical Field

[0001] This application relates to the field of vehicle interiors, and particularly to a starry sky roof for a vehicle sunroof. Background Art

[0002] With the continuous development of the automotive industry, in addition to pursuing driving safety, people are gradually increasing their attention to driving and riding comfort. Installing ambient lights in the vehicle can not only meet the needs of vehicle interior lighting, but also create an interior atmosphere, improve the quality of the vehicle, and increase the comfort of drivers and passengers. As a type of automotive ambient light, the starry sky roof is currently becoming increasingly popular among consumers.

[0003] For different types of vehicle roofs, the starry sky roof is mainly divided into two types. One is the starry sky roof installed on an integrated vehicle roof, that is, a vehicle roof without a sunroof glass. When making the starry sky roof, optical fibers are generally used as the light source, and holes need to be drilled in the roof inner lining board to expose one end of the optical fiber, and the remaining part of the optical fiber is fixed inside the roof inner lining board. The other is the starry sky roof installed on a vehicle roof equipped with a sunroof glass. The sunroof glass installed on the roof is part of the vehicle roof. When preparing the starry sky roof, the above-mentioned optical fibers are generally also used as the light source, and the optical fibers are arranged around the sunroof glass. In addition, microstructures need to be engraved on the inner surface of the glass, and the principle of total internal reflection of light is used to make the microstructures emit light directionally to achieve the starry sky effect.

[0004] When installing a starry sky roof on a vehicle roof with a sunroof glass, the inventor found that there are at least the following defects in the related art: Using optical fibers as the light source, the light emission angle is fixed, and it is difficult to precisely cooperate with the microstructures on the sunroof glass, so the starry sky effect is poor. On the other hand, the flexibility of engraving specific microstructures is also poor, and it is difficult to modify according to the needs of users. In addition, from the perspective of the manufacturing process, drilling holes in the roof inner lining board and engraving specific microstructures on the inner surface of the glass cause certain damage to the structures of the roof inner lining board and the sunroof glass, reducing their durability; and this process is also relatively complex and cumbersome, with low efficiency, wasting manpower and material resources, and it is difficult to achieve industrial mass production. Summary of the Invention

[0059] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art. Some technical terms that appear in the embodiments of the present application are described below.

[0060] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the drawings.

[0061] The starry sky roof of a vehicle sunroof, as the name implies, refers to adding a starry sky roof to a vehicle model equipped with a sunroof to create a starry sky effect. The traditional starry sky roof conducts the light of the light source to the vehicle ceiling through optical fibers to form a starry sky effect. For the traditional starry sky roof, each optical fiber needs to be inserted into and fixed on the ceiling, and the optical fibers can only be fixed in the part without a sunroof, while the part with a sunroof cannot be arranged. For a vehicle model with a sunroof, most of the roof area cannot present a starry sky pattern because the optical fibers cannot be arranged. To achieve a starry sky effect in the sunroof part, in terms of the light source, the existing technology usually follows the manufacturing method of the starry sky roof in ordinary vehicle models, that is, using optical fibers as the light source and arranging the optical fibers around the sunroof glass; in addition, it is also necessary to engrave microstructures on the sunroof glass, and through the principle of light reflection, the microstructures reflect the light source into the vehicle to create the effect of a starry sky roof. However, the disadvantages of this sunroof starry sky roof are also obvious. Using optical fibers as the light source makes the light emission angle fixed, so there is a phenomenon that the light cannot illuminate the microstructures on the sunroof glass, or the microstructures cannot cooperate precisely with the emitted light, resulting in an unclear starry sky effect; on the other hand, using this traditional method to make a starry sky roof will cause certain damage to both the vehicle ceiling and the sunroof glass; and once the microstructures are engraved and formed on the sunroof glass, they cannot be changed anymore, and users cannot improve or design according to their preferences, so the flexibility of this starry sky roof is also poor.

[0062] An embodiment of the present invention provides a starry sky roof for a vehicle sunroof, as Figure 1 shown, the starry sky roof includes a light source 1 and a sunroof roof 2. The sunroof roof 2 includes a sunroof glass 21, a roof steel plate 22, and a roof lining plate 23. Among them, the roof lining plate 23 is located below the roof steel plate 22, and there is a gap layer 24 between the roof lining plate 23 and the roof steel plate 22. The sunroof glass 21 passes through the roof steel plate 22 and the roof lining plate 23 and is installed by inlay; the light source 1 is arranged around the sunroof glass 21 and is located in the gap layer 24. The light source 1 includes a fixing frame 12 and a plurality of light groups 11 that position and fix the fixing frame 12; the sunroof glass 21 includes two glass layers 211 and a reflection layer 212 located between the two glass layers 211. The reflection layer 212 is uniformly mixed with reflection powder whose surface can reflect light; the light group 11 is used to emit light from multiple angles to the reflection layer 212 of the sunroof glass 21, and the reflection layer 212 is used to reflect the light emitted by the light group 11.

[0063] In a vehicle equipped with a sunroof glass 21, the installation of the sunroof glass 21 passing through the roof steel plate 22 and the roof lining plate 23 by inlay can specifically be that the sunroof glass 21 is fixed by the roof steel plate 22 in the vehicle body frame, and when laying the roof lining plate 23, it is necessary to avoid the sunroof glass 21, that is, the roof lining plate 23 does not cover the sunroof glass 21. As Figure 1As shown, the roof lining 23 is located below the roof steel plate, and there is a gap layer 24 between the roof lining 23 and the roof steel plate. The gap layer 24 can be an air gap layer 24 or can be filled with an interlayer prepared from a functional material, such as a sound insulation interlayer, a fire protection interlayer, etc.

[0064] In the starry sky roof of the vehicle sunroof provided in the embodiment of the present invention, the light source 1 is arranged around the sunroof glass 21 and is located in the gap layer 24. Specifically, the shape of the sunroof glass 21 is not unique and can be a polygon, a circle, etc. However, regardless of the shape of the sunroof glass 21, the light source 1 is always arranged around the sunroof glass 21, that is, the light source 1 is arranged around the sunroof glass 21 so that once the light source 1 is lit, the light source 1 can illuminate the entire sunroof glass 21. Therefore, the light source 1 includes a plurality of light groups 11 arranged around the sunroof glass 21. According to the different shapes of the sunroof glass 21, the setting methods of the plurality of light groups 11 are also different. For example, when the sunroof glass 21 is a quadrilateral, the plurality of light groups 11 can be arranged beside the two opposite sides of the sunroof glass 21.

[0065] As Figure 1 shown, the light source 1 further includes a fixing bracket 12 for positioning the light group 11. The light group 11 is connected to the vehicle ceiling through the fixing bracket 12. Specifically, the light group 11 is arranged in the gap layer 24 between the roof steel plate and the roof lining 23 through the fixing bracket 12.

[0066] From Figure 1 it can also be seen that the light source 1 is arranged facing the sunroof glass 21. Therefore, the light emitted by the light source 1 can be emitted to the main surface of the sunroof glass 21 facing the vehicle interior, and the light of the light source 1 can also be emitted to the side surface of the sunroof glass 21. Thus, when a plurality of light groups 11 are arranged around the sunroof glass 21 and the light-emitting surfaces of the plurality of light groups 11 are all arranged facing the sunroof glass 21, the light source 1 can emit light to the sunroof glass 21 from multiple angles.

[0067] In the starry sky roof of the vehicle sunroof provided in the embodiment of the present invention, the types of the light source 1 include a fixed light source and a movable light source. For different types of light sources, corresponding fixing brackets 12 are set, and the light group 11 is fixed at an appropriate position on the fixing bracket 12, so that the light source 1 can emit light to the sunroof glass 21 from multiple angles.

[0068] In the starry sky roof of the vehicle sunroof provided in the embodiment of the present invention, the sunroof glass 21 further includes a reflection layer 212 and two glass layers 211. The reflection layer 212 is located between the two glass layers 211, and the reflection layer 212 is uniformly doped with reflection powder capable of reflecting light. When the light of the light source 1 is emitted to the sunroof glass 21 from multiple angles, the uniformly distributed reflection powder in the reflection layer 212 can reflect the light at different angles.

[0069] In summary, the starry sky roof of the vehicle sunroof provided by the embodiment of the present invention includes a light source 1 and a sunroof glass 21 with a reflective layer 212 built therein. The light source 1 includes a plurality of light groups 11 and a fixing frame 12 for fixing the light groups 11. The plurality of light groups 11 are arranged around the sunroof glass 21 through the fixing frame 12, so that the light source 1 can irradiate the sunroof glass 21 from multiple angles, and the irradiation range of the light source 1 can cover the main surface of the entire sunroof glass 21. On the other hand, the reflective layer 212 has uniform reflective powder, so the reflective layer 212 can reflect the light emitted from multiple angles, thereby forming a starlight effect. Compared with the prior art, in the starry sky roof provided by the embodiment of the present invention, the sunroof glass 21 can be irradiated by light from multiple different angles, and can stably and effectively reflect the light, so that the light can be evenly emitted, so that passengers in the vehicle can see the starry sky effect of the sunroof glass 21 at any position in the vehicle, and the starry sky effect presented by the starry sky roof is highly reliable.

[0070] In the starry sky roof of the vehicle sunroof provided by the embodiment of the present invention, the reflective layer 212 can be a coating covering the inner surface of one of the two glass layers 211. The coating is a transparent varnish uniformly admixed with reflective powder. The transparent varnish is sprayed on the main surface of the glass layer 211 and forms a smooth and transparent film after drying. The spraying thickness is 20-90 μm. In addition, the transparent varnish also has certain corrosion resistance, ultraviolet resistance and weather resistance, etc., to delay the aging of the reflective layer 212 and can also adapt to the sunlight that is long-term irradiated on the reflective layer 212.

[0071] The reflective layer 212 can also be a film laid on the main surface of the glass layer 211. The film is made of lens glue (also called UV glue) admixed with reflective powder. The lens glue is an adhesive that can be cured only after being irradiated by ultraviolet light and is commonly used for bonding between glass products. Optionally, the reflective layer 212 film can also be made by admixing other transparent materials with reflective powder.

[0072] As Figure 1 shown, the reflective layer 212 is arranged between the two glass layers 211 of the sunroof glass 21, that is, the reflective layer 212 is fixed and clamped by the two glass layers 211, and the two glass layers 211 form a protection for the reflective layer 212, so as to avoid the influence of the temperature or humidity change inside and outside the vehicle on the reflective layer 212 and delay the aging of the reflective layer 212.

[0073] In the starry roof of the vehicle sunroof provided by the embodiment of the present invention, the reflective powder capable of reflecting light is made of a metal material or an organic gemstone material. Optionally, the reflective powder may be pearl powder. In addition, the reflective powder may also have a flat flaky structure, the surface of the flaky structure is smooth, and the reflectivity is high. The light irradiated on the surface of the reflective powder can achieve specular reflection, so that the reflective layer 212 can effectively reflect the light received on its surface.

[0074] The reflective powder is uniformly blended in the reflective layer 212. Therefore, the light irradiated on the reflective layer 212 can be reflected in all directions by the reflective powder uniformly distributed in the reflective layer 212, so that the passengers in the vehicle can see the starry sky effect at any position in the vehicle.

[0075] In addition, according to different needs of users, on the premise of not affecting the transparency of the sunroof glass 21, the starry sky pattern of the reflective layer 212 can be designed. For example, the pattern of a meteor or a moon can be designed, and it can be achieved by aggregating the reflective powder to form the outline of a meteor or a moon.

[0076] The reflective layer 212 realizes the directional reflection of the light emitted by the light source 1 by uniformly blending the reflective powder in the transparent matrix. When the passengers in the vehicle look at the sunroof glass 21, they can see the bright spots formed on the sunroof glass 21, thus creating a starry sky effect.

[0077] In the starry roof of the vehicle sunroof provided by the embodiment of the present invention, the light source 1 includes a light group 11 and a fixing frame 12 for fixing the light group 11, and the type of the light source 1 can be a fixed light source or a movable light source.

[0078] When the light source 1 is a fixed light source, the light group 11 may include a plurality of light-emitting modules 110, wherein the plurality of light-emitting modules 110 have different light-emitting directions.

[0079] Specifically, the light-emitting module 110 includes at least one light-emitting unit, that is, the light-emitting module 110 may include only one light-emitting unit 111, or include a plurality of light-emitting units 111. When the light-emitting module 110 includes only one light-emitting unit 111, the light-emitting surface of the one light-emitting unit 111 faces the sunroof glass 21. When the light-emitting module 110 includes a plurality of light-emitting units 111, the plurality of light-emitting units 111 are arranged in an array, and the light-emitting surfaces of the plurality of light-emitting units 111 in the same light-emitting module 110 all face the same direction, that is, the plurality of light-emitting units 111 have the same light projection angle, and the light rays they emit are parallel to each other and shoot at the sunroof glass 21 at the same angle.

[0080] In an embodiment of the present invention, the light group 11 is arranged around the skylight glass 21. Specifically, a plurality of light-emitting modules 110 in the light group 11 are arranged side by side or juxtaposed. Among them, the plurality of light-emitting modules 110 can be arranged side by side along the direction of the same horizontal axis, or can be arranged juxtaposed along the direction of the same vertical axis. The plurality of light-emitting modules 110 can be closely arranged, that is, two adjacent light-emitting modules 110 are in contact with each other, and there is no gap between the plurality of light-emitting modules 110. The plurality of light-emitting modules 110 can also be arranged at a fixed pitch. Figure 2 It is a schematic structural diagram of a starry sky roof of a vehicle skylight provided by an embodiment of the present invention. Among them, taking the example that a plurality of light-emitting modules 110 are arranged on one side of the skylight glass, the plurality of light-emitting modules 110 are closely arranged, that is, two adjacent light-emitting modules 110 are in contact with each other.

[0081] In the same light group 11, two adjacent light-emitting modules 110 have different light-emitting directions. Specifically, the light-emitting surfaces of the light-emitting units 111 in two adjacent light-emitting modules 110 in the light group 11 all face the skylight glass 21, but the light-emitting units 111 in two adjacent light-emitting modules 110 have different light projection angles, so that the two adjacent light-emitting modules 110 have different light-emitting directions, and the light rays emitted by the two can be projected onto the skylight glass 21 from different angles. For example, the light rays emitted by the light-emitting unit 111 in one light-emitting module 110 are parallel to a central axis of the skylight glass 21, and the light rays emitted by another light-emitting module 110 adjacent to this light-emitting module 110 are not parallel to the central axis of the skylight glass 21, but can be deflected by a certain angle clockwise or counterclockwise relative to the central axis of the skylight glass 21. Since the light group 11 includes light-emitting modules 110 with different light-emitting directions, the light group 11 can irradiate the skylight glass 21 from multiple different angles.

[0082] The plurality of light-emitting modules 110 in the light group 11 are fixed on the fixing frame 12, and the fixing frame 12 is used to position the light-emitting modules 110 and support the light-emitting modules 110. In order to enable the plurality of light-emitting modules 110 to have different light-emitting directions, the fixing frame 12 can be a polygonal cube. Figure 3A structural schematic diagram of a fixing bracket provided by an embodiment of the present invention. In a possible implementation manner, the fixing bracket 12 can be an isosceles trapezoidal cube, which has an upper bottom surface 123, a lower bottom surface (not shown), and two side waist surfaces 124. The upper bottom surface 123, the lower bottom surface, and the two side waist surfaces 124 are all rectangles, and the cube further includes two trapezoidal surfaces 125. When the isosceles trapezoidal cube fixing bracket 12 is installed in the gap layer 24, the two trapezoidal surfaces 125 of the cube are respectively attached to the inner walls of the vehicle roof steel plate 22 and the vehicle roof lining 23, so that the fixing bracket 12 is fixed in the gap layer 24, and the upper bottom surface 123 of the cube faces the skylight glass 21. A plurality of light-emitting modules 110 can be respectively fixed on the two side waist surfaces 124 and the upper bottom surface 123 of the cube. Figure 4 is Figure 3 the top view of the shown fixing bracket. Combining Figure 3 and Figure 4 it can be seen that 3 light-emitting modules 110 are respectively fixed on the two side waist surfaces 124 and the upper bottom surface 123 of the cube. Each light-emitting module 110 among the 3 light-emitting modules 110 includes a light-emitting unit 111, that is, the 3 light-emitting units 111 corresponding to the 3 light-emitting modules 110 are respectively fixed on the two side waist surfaces 124 and the upper bottom surface 123 of the fixing bracket 12. Because there is a certain angle between the upper bottom surface 123 and the waist surface, by respectively arranging the 3 light-emitting modules 110 on different surfaces of the fixing bracket 12, the light-emitting units 111 corresponding to the light-emitting modules 110 can emit light from different angles. The fixing bracket 12 can also be other polygonal cubes, and there is a certain angle between two adjacent surfaces of the polygonal cube. When a plurality of light-emitting modules 110 are respectively arranged on different surfaces of the polygonal cube, the plurality of light-emitting modules 110 can emit light from different angles.

[0083] In the embodiment of the present invention, the light group 11 can further include a light-emitting control module. The plurality of light-emitting modules 110 in the light group 11 are connected in parallel, and each light-emitting module 110 can be controlled by the light-emitting control module to be turned on and off, so that each light-emitting module 110 can present a flashing effect within a period of time. The light-emitting control module can be any device applied to the light group 11 that can control the brightness of the light. In a possible implementation manner, the light-emitting control module can control a light-emitting module 110 to alternately emit light and go out at a specific frequency during the working time, and the duration of light emission and the duration of going out can be the same or different.

[0084] The number of light-emitting modules 110 in the lighting group 11, the number of light-emitting units 111 in the light-emitting module 110, and the form in which the light-emitting module 110 blinks under the control of the light-emitting control module can be determined based on relevant dimensional parameters of the vehicle equipped with this starry sky roof. For example: the shape and main surface area of the sunroof glass 21, the space size inside the vehicle, etc. Without affecting driving safety, the lighting group 11 can also be customized according to the needs of the user.

[0085] The lighting group 11 can also include multi-angle LED lights 13. Each multi-angle LED light 13 emits light in multiple light-emitting directions, and the light-emitting devices corresponding to the light emitted in multiple light-emitting directions light up and go out independently of each other. The multi-angle LED light 13 can be any kind of LED light that can emit light from multiple different angles. In a possible implementation manner, the multi-angle LED light 13 includes a plurality of series-connected or parallel-connected LED chips and a horn-shaped support frame 132. Figure 5 A schematic structural diagram of a multi-angle LED light provided by an embodiment of the present invention. As can be seen from the figure, a cavity 133 is formed inside the horn-shaped support frame 132. A plurality of LED chips 131 are circumferentially encapsulated on the inner wall of the end with a larger opening of the horn-shaped support frame 132. The light-emitting surfaces corresponding to the plurality of LED chips 131 have different light-emitting angles, enabling the multi-angle LED light 13 to emit light from multiple different angles.

[0086] A plurality of lighting groups 11 are arranged beside the side of the sunroof glass 21. To enable the plurality of lighting groups 11 to illuminate the entire sunroof glass 21, so that the reflective layer 212 of the sunroof glass 21 can receive light from multiple different angles, it is preferably to symmetrically arrange the plurality of lighting groups 11 beside the side of the sunroof glass 21. In a possible implementation manner, the vehicle has a rectangular sunroof glass 21. Figure 6 A schematic structural diagram of a starry sky roof of a vehicle sunroof provided by an embodiment of the present invention. As Figure 6 shown, two lighting groups 11 can be symmetrically arranged beside two opposite sides of the sunroof glass 21 to enable the light source 1 to illuminate the entire sunroof glass 21. In another possible implementation manner, four lighting groups 11 can also be provided and arranged symmetrically in pairs beside two opposite groups of sides of the sunroof glass 21 to illuminate the entire sunroof glass 21.

[0087] In an embodiment of the present invention, when the light source 1 is a movable light source, the lighting group 11 includes at least one light-emitting unit 111, and the fixing frame 12 can be used to change the position of at least one light-emitting unit 111 to change its light-emitting direction. Figure 7 A schematic structural diagram of a starry sky roof of a vehicle sunroof provided by an embodiment of the present invention. As Figure 7As shown, the fixing bracket 12 includes a rotating shaft 121 and a base 122. Among them, the base 122 is fixed on the inner wall of the roof lining 23 for positioning the light source 1; one end of the rotating shaft 121 is rotatably connected to the base 122, and the other end of the rotating shaft 121 is fixedly connected with a light group 11. The rotating shaft 121 can drive the light group 11 to rotate, so that the light source 1 moves on the skylight glass 21, so that the light source 1 can emit light to the skylight glass 21 from multiple different angles, creating a movable starlight effect. The rotating shaft 121 may include two sections of shafts connected by bending. The first section of shaft is perpendicular to the surface of the base 122, and the second section of shaft is inclined relative to the first section of shaft, as Figure 7 shown. In other embodiments, the rotating shaft 121 may also be a straight shaft, inclined relative to the surface of the base 122.

[0088] Among them, a motor (not shown in the figure) for driving the rotating shaft 121 to rotate is further provided in the base 122. A shaft hole is provided on the surface of the base 122. The rotating shaft 121 is inserted into the shaft hole and connected to the motor inside the base 122. Driven by the motor, the rotating shaft 121 can rotate on its own at the shaft hole, and the rotation range is 0°-180°. Since the other end of the rotating shaft 121 is fixed to the light emitting unit 111, the rotating shaft 121 can drive the light emitting unit 111 to rotate together while rotating on its own, so that the light emitting unit 111 can move circumferentially in a preset plane.

[0089] Figure 8 It is a schematic structural diagram of a starry sky roof of a vehicle skylight provided by an embodiment of the present invention. It shows that when the light source is a movable light source, the rotation range 3 of the light emitting unit 111 in the light group 11 driven by the rotating shaft 121, from Figure 8 It can be seen that when the light emitting unit 111 rotates to different directions, light is emitted from the direction it rotates to the skylight glass 21. Therefore, during the rotation of the light group 11, the skylight glass 21 can receive light from multiple angles. Optionally, the rotating shaft 121 can also move or rotate in other forms under the drive of the motor, so that the light group 11 can irradiate the skylight glass 21 from multiple angles.

[0090] In the embodiment of the present invention, when the light source 1 is a movable light source, multiple light groups 11 are arranged beside the side of the skylight glass 21. In order to enable the multiple light groups 11 to illuminate the entire skylight glass 21 and enable the reflective layer 212 of the skylight glass 21 to receive light from multiple different angles, it is preferable to symmetrically arrange the multiple light groups 11 beside the side of the skylight glass 21. Figure 9 It is a schematic structural diagram of a starry sky roof of a vehicle skylight provided by this application. In a possible implementation manner, the vehicle has a rectangular skylight glass 21, such as Figure 9As shown, when the light source 1 is a movable light source, four light groups 11 can be arranged pairwise opposite to each other beside the four side edges of the rectangular skylight glass 21, so that the light source 1 can illuminate the entire skylight glass 21.
