[0001] This application claims priority to Chinese patent application filed on October 25, 2024, with application number 202422596431.0 and entitled "Starry Sky Interior Parts, Carriage Headliner and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of starry sky interior trim technology, and more particularly to a starry sky interior trim, a car roof, and a vehicle. Background Technology

[0003] With the increasing demand for vehicle personalization, the vehicle modification market has gradually emerged, giving rise to car headliners with starry sky interior trim. Starry sky interior trim is a decorative component installed on the car headliner. By arranging numerous small light sources on it, it creates a visual effect reminiscent of a starry sky, reflecting people's pursuit of a romantic and unique car interior environment. Among these efforts, how to design starry sky interior trim to enhance the user experience has become an important topic in the industry. Summary of the Invention

[0004] Embodiments of this application provide a starry sky interior trim, a vehicle roof, and a vehicle to solve the problems of the light source of the starry sky interior trim being easily damaged by bumps and the poor light emission effect of the starry sky interior trim in the related art.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a starry sky interior decoration, including a light source and a fabric layer; the light source includes a carrier layer and an array of light-emitting elements disposed on the carrier layer, the array of light-emitting elements including a plurality of light-emitting elements, the light-emitting surface of the light-emitting elements facing a first side of the carrier layer; the fabric layer is stacked on the first side of the carrier layer, the fabric layer having a cutout at the position corresponding to the light-emitting element, the cutout allowing light emitted by the light-emitting element to pass through.

[0007] The starry sky interior decoration in this embodiment utilizes a fabric layer stacked on the light-emitting side of the light source. The fabric layer has perforations at the positions of the corresponding light-emitting elements, allowing light emitted from the elements to pass through the fabric layer. This ensures normal light emission from the starry sky interior decoration, eliminating the need for optical fibers to guide the light source, thus simplifying the structure and reducing cost. Simultaneously, the fabric layer, positioned on the first side of the supporting layer, protects the light source, preventing the light-emitting elements from being directly exposed to the fabric layer's surface. This avoids damage to the light-emitting elements from impacts, reducing maintenance costs. Furthermore, each light-emitting element (i.e., a light spot) in the light-emitting element array is an independent light-emitting unit, allowing for individual control of its luminous effect (e.g., color, brightness, and flicker frequency), thereby enhancing the overall luminous effect of the starry sky interior decoration.

[0008] In some embodiments of the first aspect, the cutout portion is a first light-transmitting hole that penetrates the fabric layer, and the area of ​​the first light-transmitting hole is larger than the area of ​​the light-emitting surface. This arrangement allows the light-emitting surface of the light-emitting element to be better aligned with the cutout portion, preventing the fabric layer around the cutout portion from obstructing the light-emitting surface of the light-emitting element.

[0009] In some embodiments of the first aspect, the fabric layer is a woven fabric layer, and the perforated portion is a structural hole in the fabric layer. This configuration eliminates the need for additional perforations in the fabric layer, simplifying the manufacturing process.

[0010] In some embodiments of the first aspect, the perforated portion is a first micro-hole array, which includes a plurality of first micro-holes penetrating the fabric layer, the diameter of which is less than or equal to 0.1 mm. This configuration allows the first micro-hole array to better prevent larger objects from contacting or bumping into the light-emitting element while ensuring normal light transmission, thus providing better protection for the light-emitting element; it also reduces the impact of the perforated portion on the appearance of the starry sky interior decoration.

[0011] In some embodiments of the first aspect, the area of ​​the first micro-aperture array is larger than the area of ​​the light-emitting surface. This arrangement allows the light-emitting surface of the light-emitting element to be better aligned with the first micro-aperture array, preventing the fabric layer surrounding the first micro-aperture array from obstructing the light-emitting surface of the light-emitting element.

[0012] In some embodiments of the first aspect, the diameter of the first micropore is less than or equal to 0.03 mm. This configuration ensures normal light transmission while preventing smaller impurities from entering the first micropore, thus guaranteeing the light emission effect of the light-emitting element.

[0013] In some embodiments of the first aspect, the fabric layer includes a first surface disposed near the light source and a second surface disposed away from the light source; the perforated portion includes a second light-transmitting hole and a second micro-hole array, the second light-transmitting hole being a blind hole disposed on the first surface, and the second micro-hole array disposed on the bottom wall of the second light-transmitting hole, the second micro-hole array including a plurality of second micro-holes penetrating the second surface, the diameter of the second micro-holes being less than or equal to 0.1 mm. This configuration helps to reduce light loss when the light emitted by the light-emitting element passes through the perforated portion, and also better prevents larger objects from contacting or bumping into the light-emitting element, thereby providing better protection for the light-emitting element.

[0014] In some embodiments of the first aspect, the thickness d of the fabric layer and the depth h of the second light-transmitting hole satisfy the condition: h = (1 / 2 to 2 / 3)d. This arrangement avoids both excessively low structural strength of the fabric layer and reduces light loss when the light emitted by the light-emitting element passes through the perforated portion.

[0015] In some embodiments of the first aspect, the area of ​​the second light-transmitting hole is larger than the area of ​​the light-emitting surface. This arrangement allows the light-emitting surface of the light-emitting element to be better aligned with the cutout portion, preventing the fabric layer around the cutout portion from obstructing the light-emitting surface of the light-emitting element.

[0016] In some embodiments of the first aspect, the diameter of the second micropore is less than or equal to 0.03 mm. This configuration ensures normal light transmission while preventing smaller impurities from entering the second micropore, thus guaranteeing the light emission effect of the light-emitting element.

[0017] In some embodiments of the first aspect, the fabric layer is a natural leather layer or a suede-like layer. This configuration prevents the fabric layer from cracking when perforations are created, thus facilitating the creation of the perforations.

[0018] In some embodiments of the first aspect, the light-emitting element extends into the cutout portion. This arrangement is advantageous in increasing the intensity of the light emitted by the light-emitting element after passing through the cutout portion.

[0019] In some embodiments of the first aspect, the diameter of the light-emitting surface of the light-emitting element ranges from 0.15 mm to 2 mm. This configuration avoids the light emitted by the light-emitting element being too glaring or too dim, thereby contributing to a better luminous effect for the starry sky interior decoration.

[0020] In some embodiments of the first aspect, the starry sky interior trim also includes a light-blocking layer, which is stacked on the side of the light source away from the fabric layer. This arrangement allows the starry sky interior trim to have a light-blocking effect, enabling it to be used as a sunshade on the roof of a vehicle with a sunroof.

[0021] Secondly, embodiments of this application provide a car roof, including a roof body and the starry sky interior trim described in the first aspect, wherein the starry sky interior trim and the roof body are stacked together.

[0022] The beneficial effects of the car roof strip in this embodiment are the same as those of the starry sky interior trim in the first aspect, and will not be repeated here.

[0023] Thirdly, this application provides a car roof, including a roof body, a first roller, a first driving device, and the starry sky interior trim described in the first aspect; the roof body has a sunroof, the first roller is rotatably disposed at the edge of the sunroof, the starry sky interior trim is connected to the first roller, the first driving device is connected to the first roller and is used to drive the first roller to rotate, so that the starry sky interior trim gradually winds around the first roller to open the sunroof.

[0024] The beneficial effects of the car roof strip in this embodiment are the same as those of the starry sky interior trim in the first aspect, and will not be repeated here.

[0025] In some embodiments of the third aspect, the car roof further includes a second roller, a transmission belt, and a second drive device. The second roller and the first roller are rotatably mounted on opposite edges of the sunroof. One end of the transmission belt is wound around the first roller, and the other end is wound around the second roller. One end of the starry sky interior trim is connected to the transmission belt, and the other end is connected to the first roller. The second drive device is connected to the second roller and is used to drive the second roller to rotate, causing the transmission belt to gradually detach the starry sky interior trim from the first roller to close the sunroof. This arrangement allows for precise control of the speed at which the starry sky interior trim opens and closes the sunroof, preventing damage to the trim caused by excessively rapid opening and closing.

[0026] Fourthly, embodiments of this application provide a vehicle, including a passenger compartment and wheels disposed at the bottom of the passenger compartment. The passenger compartment includes a bottom wall, side walls, and a roof as described in the second or third aspect. The side walls are connected between the roof and the bottom wall. The starry sky interior trim of the roof is disposed on the inner side of the roof body.

[0027] The beneficial effects of the vehicle belt in this embodiment are the same as those of the starry sky interior trim in the first aspect, and will not be repeated here. Attached Figure Description

[0047] With the increasing demand for vehicle personalization, the vehicle modification market has gradually emerged, giving rise to car headliners with starry sky interior trim. Starry sky interior trim is a decorative component installed on the car headliner. By arranging numerous small light sources on it, it creates a visual effect reminiscent of a starry sky, reflecting people's pursuit of a romantic and unique car interior environment. Among these efforts, how to design starry sky interior trim to enhance the user experience has become an important topic in the industry.

[0048] Figure 1 shows a schematic diagram of a starry sky interior decoration component in the related art. The starry sky interior decoration component includes a light source 01 and a decorative component body 02. The decorative component body 02 includes a plastic base plate 021 and an inner fabric layer 022 stacked on the inner side of the plastic base plate 021. The light source 01 includes a light source body 011 and an optical fiber 012. The light source body 011 is disposed on the outer side of the decorative component body 02 (i.e., the upper side of the decorative component body 02 in Figure 1). The outer end of the optical fiber 012 (i.e., the upper end in Figure 1) is connected to the light source body 011, and the inner end of the optical fiber 012 (i.e., the lower end in Figure 1) is inserted into the decorative component body 02 and is flush with the surface of the inner fabric layer 022.

[0049] The light emitted by the light source body 011 is transmitted through the optical fiber 012. Because the optical fiber 012 is very thin, it only appears as small dots of light on the decorative part body 02, like stars. Moreover, by controlling parameters such as the color, brightness, and flicker frequency of the light source body 011, different starry sky effects can be simulated, such as static starry sky and dynamic effects such as shooting stars.

[0050] The manufacturing process of this starry sky interior decoration is as follows: After the decorative body 02 is manufactured, an optical fiber 012 is passed through the through hole on the decorative body 02, with a certain length allowance left on the inner side of the decorative body 02 (i.e., the lower side of the decorative body 02 in Figure 1). The optical fiber 012 on the outer side of the decorative body 02 is connected to the light source body 011; then, the protruding optical fiber 012 on the inner side of the decorative body 02 is trimmed so that the end face of the optical fiber 012 is flush with the surface of the inner fabric layer 022.

[0051] In the related technology, the interior decoration of this starry sky requires trimming the protruding optical fiber 012 on the inner side of the decorative body 02 during the manufacturing process. This can easily lead to uneven trimming, making the trimmed end face of the optical fiber 012 feel rough to the touch and potentially causing injury to the user.

[0052] To address the issue of the prickly feel of the trimmed end face of optical fiber 03, as shown in Figure 2, the related technology provides another starry sky interior trim, which differs from the starry sky interior trim in Figure 1 in that: the inner end of the optical fiber 012 in the starry sky interior trim in Figure 2 is provided with an enlarged portion 0121, and the enlarged portion 0121 abuts against the surface of the inner fabric layer 022.

[0053] By setting the enlarged part 0121, when installing the optical fiber 012, the enlarged part 0121 acts as a limit, and the optical fiber 012 can be directly pulled tight from the outside of the decorative part body 02 so that the enlarged part 0121 abuts against the surface of the inner fabric layer 022. In this way, there is no need to trim the optical fiber 012, thereby avoiding the problem of uneven trimming.

[0054] However, the bulge 0121 is exposed on the inside of the decorative body 02, making it susceptible to damage from collisions with other objects, thus increasing the maintenance cost of the starry sky interior decoration. Furthermore, the fact that multiple optical fibers 012 are connected to the same light source body 011 makes it impossible to individually control the light output of each light point (i.e., the bulge 0121 of the optical fiber 012) on the decorative body 02, thereby also affecting the luminous effect of the starry sky interior decoration.

[0055] Therefore, this application provides a starry sky interior trim, a car roof, and a vehicle. By setting an array of light-emitting elements on the load-bearing layer to form a light source, and setting a fabric layer on the light-emitting side of the light source, the fabric layer has hollowed-out parts at the positions of the corresponding light-emitting elements. In this way, while ensuring that the light source emits light normally, the light-emitting elements are prevented from being damaged by bumps. At the same time, each light-emitting element (i.e., light spot) can be controlled individually, which helps to improve the luminous effect of the starry sky interior trim.

[0056] The technical solutions in some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0057] Figure 3 is a schematic diagram of the structure of the starry sky interior decoration 100 in the first embodiment of this application. As shown in Figure 3, the starry sky interior decoration 100 includes a light source 1 and a fabric layer 2. The light source 1 includes a carrier layer 11 and a light-emitting element array 12 disposed on the carrier layer 11. The light-emitting element array 12 includes a plurality of light-emitting elements 121, and the light-emitting surface 1211 of the light-emitting element 121 faces the first side of the carrier layer 11 (i.e., the light-emitting side of the light source 1, such as the lower side of the carrier layer 11 in Figure 3). As shown in Figure 3, the light-emitting element 121 can be an LED (light emitting diode), such as a Mini-LED. Of course, the light-emitting element 121 is not limited to this, and the light-emitting element 121 can also be other electroluminescent devices.

[0058] Fabric layer 2 is stacked on the first side of carrier layer 11. Fabric layer 2 has a cutout 21 at the position corresponding to light-emitting element 121, allowing light emitted from light-emitting element 121 to pass through. As shown in Figure 3, an adhesive layer 4 (such as glue layer) can be provided between fabric layer 2 and carrier layer 11 to bond fabric layer 2 and carrier layer 11 together. Of course, the connection between fabric layer 2 and carrier layer 11 is not limited to adhesive; fabric layer 2 and carrier layer 11 can also be connected together by snap-fit, screw connection, or other methods.

[0059] The starry sky interior decoration 100 in this embodiment of the application incorporates a fabric layer 2 stacked on the light-emitting side of the light source 1. The fabric layer 2 has a perforated portion 21 at the position corresponding to the light-emitting element 121, allowing light emitted by the light-emitting element 121 to pass through the fabric layer 2 via the perforated portion 21. This ensures normal light emission from the starry sky interior decoration 100, eliminating the need for optical fibers to guide light from the light source 1, thus simplifying the structure and reducing the cost of the starry sky interior decoration 100. Simultaneously, the fabric layer 2, positioned on the first side of the supporting layer 11, provides protection to the light source 1, preventing the light-emitting element 121 from being directly exposed to the surface of the fabric layer 2. This prevents damage to the light-emitting element 121 from impacts, reducing maintenance costs for the light source 1. Furthermore, each light-emitting element 121 (i.e., a light spot) in the light-emitting element array 12 is an independent light-emitting unit, allowing for individual control of its luminous effect (e.g., luminous color, luminous brightness, and flashing frequency), thereby improving the overall luminous effect of the starry sky interior decoration 100.

[0060] To ensure that the light-emitting surface 1211 of the light-emitting element 121 is better aligned with the hollowed-out portion 21, in some embodiments, as shown in FIG3, the hollowed-out portion 21 is a first light-transmitting hole that penetrates the fabric layer 2, and the area of ​​the first light-transmitting hole is larger than the area of ​​the light-emitting surface 1211. With this arrangement, during the bonding process between the fabric layer 2 and the light source 1, the larger area of ​​the first light-transmitting hole can better absorb the alignment tolerance between the light-emitting element 121 and the hollowed-out portion 21, allowing the light-emitting surface 1211 of the light-emitting element 121 to better align with the hollowed-out portion 21. This prevents the fabric layer 2 surrounding the hollowed-out portion 21 from obstructing the light-emitting surface 1211 of the light-emitting element 121, thereby ensuring the luminous effect of the starry sky interior decoration 100.

[0061] In some embodiments, as shown in FIG3, the fabric layer 2 is a woven fabric layer (such as a fabric layer), and the cutout portion 21 is a structural hole in the fabric layer 2. By making full use of the structural holes of the fabric layer 2 itself as the cutout portion 21, it is not necessary to open the cutout portion 21 on the fabric layer 2, which simplifies the manufacturing process and helps to reduce the manufacturing cost of the starry sky interior part 100.

[0062] Among them, the structural pores of fabric layer 2 refer to the gaps or holes formed in the fabric layer, which may be caused by the fabric structure and the arrangement of the braided threads.

[0063] To ensure the starry sky interior trim 100 has a better luminous effect, in some embodiments, as shown in Figures 3 and 4 (Figure 4 is a bottom view of the starry sky interior trim 100 in Figure 3 at the cutout portion 21), the diameter D of the light-emitting surface 1211 of the light-emitting element 121 ranges from 0.15mm to 2mm. This setting avoids the diameter D of the light-emitting surface 1211 being too large or too small. If the diameter D of the light-emitting surface 1211 is too large, the emitted light will be too dazzling, affecting the luminous effect of the starry sky interior trim 100; if the diameter D of the light-emitting surface 1211 is too small, the emitted light will be too dim, also affecting the luminous effect of the starry sky interior trim 100. Research has found that when the diameter D of the light-emitting surface 1211 is in the range of 0.15mm to 2mm, it can avoid the light emitted by the light-emitting element 121 being either too dazzling or too dim, thus contributing to a better luminous effect for the starry sky interior trim 100.

[0064] Furthermore, when the diameter D of the light-emitting surface 1211 is in the range of 0.3mm to 1mm, it can better avoid the light emitted by the light-emitting element 121 being too glaring or too dim, thereby helping the starry sky interior part 100 to have a better light-emitting effect.

[0065] The shape of the light-emitting surface 1211 is not unique. For example, as shown in Figure 4, the light-emitting surface 1211 can be square. However, it is not limited to this. The shape of the light-emitting surface 1211 can also be circular or other polygonal, such as triangle, pentagon, and hexagon.

[0066] It's important to understand that for a circular light-emitting surface 1211, its diameter is its most intuitive dimensional description. For a non-circular light-emitting surface 1211, such as a square or rectangular surface, this "diameter" is an equivalent diameter. This equivalent diameter is usually determined based on some equivalence rule of the area or physical dimensions of the light-emitting surface 1211. For example, for a square light-emitting surface 1211, its equivalent diameter could be the length of its diagonal, or it could be the diameter of a circle after the area of ​​the light-emitting surface 1211 has been equivalently converted to a circle; it could also be the diameter of the circumcircle of the light-emitting surface 1211.

[0067] In some embodiments, as shown in FIG3, the light source 1 has a connection interface 13 for connecting to a power supply line.

[0068] Figure 5 is a structural schematic diagram of the starry sky interior trim 100 in the second embodiment of this application. The main difference between the starry sky interior trim 100 in Figure 5 and the starry sky interior trim 100 in Figure 3 is that the starry sky interior trim 100 in Figure 5 adds a light-shielding layer 3 on the basis of the starry sky interior trim 100 in Figure 3, as described below:

[0069] As shown in Figure 5, the starry sky interior trim 100 also includes a light-blocking layer 3, which is stacked on the side of the light source 1 away from the fabric layer 2. By setting the light-blocking layer 3, the starry sky interior trim 100 can have a light-blocking effect, so that the starry sky interior trim 100 can be applied to the roof of a car with a sunroof to be used as a sunshade.

[0070] In some embodiments, as shown in FIG5, the light-blocking layer 3, the fabric layer 2, and the light source 1 are all flexible layers. With this configuration, the starry sky interior trim 100 can be rolled up on a roller and used as a roller blind. As shown in FIG5, the light-blocking layer 3 can be a base fabric layer. With this configuration, the base fabric layer can act as a buffer, eliminating noise when the starry sky interior trim 100 is rolled up on the roller.

[0071] Of course, the light-shielding layer 3 is not limited to the bottom fabric layer; the light-shielding layer 3 can also be a film structure made of other light-shielding materials.

[0072] Figure 6 is a structural schematic diagram of the starry sky interior trim 100 in the third embodiment of this application; Figure 7 is a partial enlarged view of the starry sky interior trim 100 in Figure 6 at the hollowed-out portion 21; and Figure 8 is a bottom view of the starry sky interior trim 100 in Figure 6 at the hollowed-out portion 21. The main difference between the starry sky interior trim 100 in Figures 6-8 and the starry sky interior trim 100 in Figure 3 is that the structure of the hollowed-out portion 21 is different, as described below:

[0073] As shown in Figures 6 and 7, the perforated portion 21 is a first micro-perforation array, which includes multiple first micro-holes 211 penetrating the fabric layer 2. The diameter of each first micro-hole 211 is less than or equal to 0.1 mm. By setting the perforated portion 21 as a first micro-perforation array, the smaller diameter of the first micro-holes 211 allows for better light transmission while preventing larger objects from contacting or bumping into the light-emitting element 121, thus better protecting the light-emitting element 121 and preventing damage. Furthermore, setting the perforated portion 21 as a first micro-perforation array reduces its impact on the appearance of the starry sky interior trim 100, making it more aesthetically pleasing.

[0074] The bonding process between the fabric layer 2 and the light source 1 of the starry sky interior part 100 is as follows: an adhesive layer 4 is covered on the fabric layer 2, laser holes are made at the position of the fabric layer 2 corresponding to the light-emitting element 121 to form a first micro-hole array, and then the fabric layer 2 and the light source 1 are aligned and bonded together by vacuum bonding process.

[0075] The diameter of the first micro-aperture 211 should not be too large. If the diameter is too large, smaller impurities (such as dust) can easily enter the first micro-aperture 211, affecting the light emission effect of the light-emitting element 121. Research has shown that when the diameter of the first micro-aperture 211 is less than or equal to 0.03 mm, the first micro-aperture array can prevent smaller impurities from entering the first micro-aperture 211 while ensuring normal light transmission, thereby ensuring the light emission effect of the light-emitting element 121.

[0076] To ensure that the light-emitting surface 1211 of the light-emitting element 121 is better aligned with the first micro-aperture array, in some embodiments, as shown in Figures 6 and 8, the area of ​​the first micro-aperture array is larger than the area of ​​the light-emitting surface 1211. With this configuration, during the bonding process between the fabric layer 2 and the light source 1, the larger area of ​​the first micro-aperture array can better absorb the alignment tolerance between the light-emitting element 121 and the first micro-aperture array, allowing the light-emitting surface 1211 of the light-emitting element 121 to better align with the first micro-aperture array. This prevents the fabric layer 2 surrounding the first micro-aperture array from obstructing the light-emitting surface 1211 of the light-emitting element 121, thereby ensuring the light-emitting effect of the light-emitting element 121.

[0077] It's important to understand that the area of ​​a hole array refers to the size of the planar region occupied by the entire array containing all the holes. This includes the area occupied by the holes themselves and the area of ​​the spaces between them. For regularly arranged holes, such as a rectangular array, suppose there are n holes in each row and m holes in each column. The diameter of each hole is d1, the horizontal spacing between adjacent holes is x (the horizontal dimension of the space between adjacent holes), and the vertical spacing is y (the vertical dimension of the space between adjacent holes). Then, the length of the hole array L = (n-1)x + nd1, the width W = (m-1)y + md1, and the area of ​​the hole array A = LW. For example, as shown in Figure 8, each row of the first micro-pore array has 5 first micro-pores 211. The diameter of the first micro-pore 211 is 0.1 mm, the horizontal spacing is 0.05 mm, and the vertical spacing is 0.05 mm. Then, n = 5, m = 4, d1 = 0.1 mm, x = y = 0.05 mm. The length of the first micro-pore array can be calculated as L = (5-1) × 0.05 + 5 × 0.1 = 0.7 mm; the width as W = (4-1) × 0.05 + 4 × 0.1 = 0.55 mm; and the area as A = 0.7 × 0.55 = 0.385 mm². 2 .

[0078] In some embodiments, as shown in Figures 6 and 7, the fabric layer 2 is a natural leather layer or a suede-like layer. This configuration prevents the fabric layer 2 from cracking when the perforated portion 21 is provided, thus facilitating the creation of the perforated portion 21.

[0079] Natural leather is a layer of material obtained from animal hides through a series of physical and chemical processing. Its main component is collagen fibers, which are naturally formed during the animal's growth process and, after processing, become leather materials with unique properties. Natural leather can be pigskin, sheepskin, cowhide, etc., and no specific limitation is made here.

[0080] Imitation suede is a synthetic material that mimics the appearance and feel of natural suede. It belongs to the category of artificial leather and is primarily used as a substitute for natural suede, finding wide application in clothing, footwear, home furnishings, and automotive interiors. The main components of imitation suede are polyurethane (PU) and fiber components. Polyurethane is the most important component. Through special processing techniques, polyurethane can be formed into a suede-like surface, providing leather-like flexibility and abrasion resistance. Furthermore, polyurethane has good chemical stability and a certain degree of resistance to some common chemicals (such as detergents, mild acid and alkali solutions), making imitation suede material convenient for daily use and cleaning. The fiber component increases the material's strength and three-dimensional appearance.

[0081] Figure 9 is a structural schematic diagram of the starry sky interior trim 100 in the fourth embodiment of this application. The main difference between the starry sky interior trim 100 in Figure 9 and the starry sky interior trim 100 in Figure 3 is that the structure of the hollowed-out portion 21 is different, as described below:

[0082] As shown in Figure 9, the fabric layer 2 includes a first surface 2a located near the light source 1 and a second surface 2b located away from the light source 1; the cutout portion 21 includes a second light-transmitting hole 212 and a second micro-hole array 213. The second light-transmitting hole 212 is a blind hole and is located on the first surface 2a. The second micro-hole array 213 is located on the bottom wall of the second light-transmitting hole 212. The second micro-hole array 213 includes a plurality of second micro-holes 2131 that penetrate the second surface 2b. The diameter of the second micro-holes 2131 is less than or equal to 0.1 mm.

[0083] By combining the perforated portion 21 with the second micro-aperture array 213, the depth of the second micro-apertures 2131 in the second micro-aperture array can be reduced. This helps to reduce light loss when the light emitted by the light-emitting element 121 passes through the perforated portion 21, thus ensuring the luminous effect of the starry sky interior decoration 100. Simultaneously, the second micro-aperture array 213 is located on the second surface 2b, which better prevents larger objects from contacting or bumping into the light-emitting element 121, thus better protecting the light-emitting element 121 and preventing damage.

[0084] The bonding process between the fabric layer 2 and the light source 1 of the starry sky interior component 100 is as follows: an adhesive layer 4 is covered on the fabric layer 2, and laser holes are made at the position of the fabric layer 2 corresponding to the light-emitting element 121 to form a second light-transmitting hole 212; then the size of the laser spot is adjusted to perform micro-hole laser engraving to form a second micro-hole array 213, and then the fabric layer 2 and the light source 1 are aligned and bonded together by vacuum bonding process.

[0085] In some embodiments, as shown in FIG9, the thickness d of the fabric layer 2 and the depth h of the second light-transmitting hole 212 satisfy: h = (1 / 2 to 2 / 3)d. This setting avoids the second light-transmitting hole 212 being too large or too small. If the depth h of the second light-transmitting hole 212 is too large, the structural strength of the fabric layer 2 will be reduced, making it easily damaged under external force. If the depth h of the second light-transmitting hole 212 is too small, the depth of the second micro-hole 2131 will be large, increasing the light loss of the light emitted by the light-emitting element 121 when passing through the hollow portion 21. By satisfying the depth h of the second light-transmitting hole 212 as h = (1 / 2 to 2 / 3)d, both the structural strength of the fabric layer 2 is avoided being too low, and the light loss of the light emitted by the light-emitting element 121 when passing through the hollow portion 21 is reduced, thereby helping to ensure the luminous effect of the starry sky interior decoration 100.

[0086] In some embodiments, as shown in FIG9, the area of ​​the second light-transmitting hole 212 is larger than the area of ​​the light-emitting surface 1211. With this configuration, during the process of the fabric layer 2 and the light source 1 being bonded together, the larger area of ​​the second light-transmitting hole 212 can better absorb the alignment tolerance between the light-emitting element 121 and the hollow portion 21, so that the light-emitting surface 1211 of the light-emitting element 121 is better aligned with the hollow portion 21, and the fabric layer 2 around the hollow portion 21 is prevented from blocking the light-emitting surface 1211 of the light-emitting element 121, thereby ensuring the light-emitting effect of the starry sky interior decoration 100.

[0087] In some embodiments, the diameter of the second micro-aperture 2131 is less than or equal to 0.03 mm. In this way, the second micro-aperture array 213 can prevent some small impurities from entering the second micro-aperture 2131 while ensuring normal light transmission, thereby ensuring the light emission effect of the light-emitting element 121.

[0088] In some embodiments, as shown in FIG9, the fabric layer 2 is a natural leather layer or a suede-like layer. This configuration makes it less prone to cracking when the perforated portion 21 is provided on the fabric layer 2, thus facilitating the creation of the perforated portion 21.

[0089] Figure 10 is a structural schematic diagram of the starry sky interior decoration component 100 in the fifth embodiment of this application. The main difference between the starry sky interior decoration component 100 in Figure 10 and the starry sky interior decoration component 100 in Figure 3 is that the positional relationship between the light-emitting element 121 and the hollowed-out portion 21 is different, as described below:

[0090] As shown in Figure 10, the light-emitting element 121 extends into the hollow portion 21, for example, the light-emitting element 121 extends into the second light-transmitting hole 212. This arrangement can shorten the distance between the light-emitting surface 1211 of the light-emitting element 121 and the second micro-hole array 213, thereby improving the intensity of the light emitted by the light-emitting element 121 after passing through the hollow portion 21, and thus helping to ensure the light-emitting effect of the starry sky interior decoration 100.

[0091] The above is a structural description of the starry sky interior trim 100 in the embodiments of this application. The application scenarios of the starry sky interior trim 100 will be described in detail below.

[0092] Figure 11 is a schematic diagram of the vehicle structure in some embodiments of this application. As shown in Figure 11, the vehicle includes a carriage 1000 and wheels 2000 disposed at the bottom of the carriage 1000. The carriage 1000 includes a bottom wall 1100, a side wall 1200, and a roof 1300. The side wall 1200 is connected between the roof 1300 and the bottom wall 1100.

[0093] The vehicles can be SUVs, MPVs, sedans, motorhomes, vans, buses, trucks, etc., without specific restrictions.

[0094] Figure 12 is a bottom view of the carriage roof 1300 in the first embodiment of this application, and Figure 13 is a cross-sectional view (AA) of the carriage roof 1300 in Figure 12. As shown in Figures 12 and 13, the carriage roof 1300 includes a roof body 200 and a starry sky interior trim 100. The starry sky interior trim 100 is stacked with the roof body 200, and the starry sky interior trim 100 is disposed on the inner side of the roof body 200 (i.e., the side of the roof body 200 closer to the interior of the carriage 1000).

[0095] The canopy body 200 can be made of plastic sheeting, but is not limited to this; other materials can also be used depending on the actual situation. The starry sky interior trim 100 includes a light source 1 and a fabric layer 2. The light source 1 includes a support layer 11 and a light-emitting element array 12 disposed on the support layer 11. The light-emitting element array 12 includes multiple light-emitting elements 121, with the light-emitting surface 1211 of the light-emitting elements 121 facing the first side of the support layer 11. The fabric layer 2 is stacked on the first side of the support layer 11, and the fabric layer 2 has a perforated portion 21 at the position corresponding to the light-emitting element 121, allowing light emitted by the light-emitting element 121 to pass through. An adhesive layer 4 (such as an adhesive layer) can be disposed between the fabric layer 2 and the support layer 11, bonding the fabric layer 2 and the support layer 11 together. The specific structure of the perforated portion 21 can be referred to the description above and will not be repeated here.

[0096] Figure 14 is a bottom view of the carriage roof 1300 in the second embodiment of this application, and Figure 15 is a BB sectional view of the carriage roof 1300 in Figure 14. The main difference between the carriage roof 1300 in Figures 14 and 15 and the carriage roof 1300 in Figures 12 and 13 is that the carriage roof 1300 in Figures 14 and 15 has a sunroof 210, and the starry sky interior trim 100 can be rolled up on a scroll to open the sunroof 210, as described below:

[0097] As shown in Figures 14 and 15, the carriage roof 1300 includes a roof body 200, a first roller 310, a first drive device 320, and a starry sky interior trim 100. The roof body 200 has a sunroof 210. The first roller 310 is rotatably disposed at the edge of the sunroof 210. The first roller 310 extends along the width direction Y of the roof body 200. A guide rail 410 is also provided at the edge of the sunroof 210. The guide rail 410 extends along the length direction X of the roof body 200. The first end of the starry sky interior trim 100 is connected to the first roller 310, and the second end of the starry sky interior trim 100 is connected to a slider 420. The slider 420 is slidably connected to the guide rail 410.

[0098] The carriage roof 1300 also includes an elastic member 430, which is used to apply an elastic force to the second end of the starry sky interior trim 100 that can move away from the first spool 310, such as the elastic force pointing to the left as shown in Figure 14.

[0099] The first driving device 320 is connected to the first roller 310 and is used to drive the first roller 310 to rotate, so that the starry sky interior decoration 100 is gradually wound around the first roller 310 to open the sunroof 210; when it is necessary to close the sunroof 210, the second end of the starry sky interior decoration 100 moves away from the first roller 310 under the action of the elastic force of the elastic member 430, so that the starry sky interior decoration 100 gradually detaches from the first roller 310 to close the sunroof 210.

[0100] As shown in Figure 15, the starry sky interior decoration 100 includes a light source 1, a fabric layer 2, and a light-shielding layer 3. The light source 1 includes a support layer 11 and a light-emitting element array 12 disposed on the support layer 11. The light-emitting element array 12 includes multiple light-emitting elements 121, with the light-emitting surface 1211 of each element facing the first side of the support layer 11. The fabric layer 2 is stacked on the first side of the support layer 11, and has a cutout 21 at the position corresponding to the light-emitting element 121, allowing light emitted by the light-emitting element 121 to pass through. The light-shielding layer 3 is stacked on the side of the light source 1 away from the fabric layer 2, i.e., between the light source 1 and the ceiling body 200. An adhesive layer 4 (such as a glue layer) can be disposed between the fabric layer 2 and the support layer 11, bonding the fabric layer 2 and the support layer 11 together. The specific structure of the cutout 21 can be referred to the previous description and will not be repeated here.

[0101] In some embodiments, as shown in FIG14, the elastic component 430 is a spring, one end of which is connected to the slider 420, and the other end of which is connected to the connecting block 440 on the guide rail 410. When the starry sky interior decoration 100 is gradually wound around the first reel 310, the spring is in a stretched state to apply an elastic force to the second end of the starry sky interior decoration 100, which can move away from the first reel 310.

[0102] In some embodiments, as shown in FIG14, the first drive device 320 is a motor.

[0103] In some embodiments, as shown in Figures 14 and 15, the skylight 210 is a glass layer embedded in the ceiling body 200.

[0104] In some embodiments, as shown in FIG14, there are two guide rails 410, which are respectively disposed at the edges of opposite sides of the sunroof 210 along the width direction Y of the ceiling body 200. There are also two sliders 420, both of which are connected to the second end of the starry sky interior trim 100, and each slider 420 is slidably connected to the corresponding guide rail 410. This arrangement can prevent the starry sky interior trim 100 from tilting in the width direction Y of the ceiling body 200, thereby making the movement of the starry sky interior trim 100 more stable when opening or closing the sunroof 210.

[0105] Figure 16 is a bottom view of the carriage roof 1300 in the third embodiment of this application when the sunroof 210 is closed; Figure 17 is a CC sectional view of the carriage roof 1300 shown in Figure 16; Figure 18 is a bottom view of the carriage roof 1300 in the third embodiment of this application when the sunroof 210 is half-open; and Figure 19 is a bottom view of the carriage roof 1300 in the third embodiment of this application when the sunroof 210 is open. The main difference between the carriage roof 1300 shown in Figures 16-19 and the carriage roof 1300 shown in Figures 14 and 15 is that the starry sky interior trim 100 in the carriage roof 1300 shown in Figures 16-19 is driven by a belt drive mechanism during the opening and closing of the sunroof, as described below:

[0106] As shown in Figures 16 to 19, the carriage roof 1300 includes a roof body 200, a first roller 310, a first drive device 320, a second roller 330, a transmission belt 340, a second drive device 350, and a starry sky interior trim 100.

[0107] The canopy body 200 has a skylight 210. The second roller 330 and the first roller 310 are rotatably disposed on opposite sides of the edge of the skylight 210. One end of the transmission belt 340 is wound around the first roller 310, and the other end of the transmission belt 340 is wound around the second roller 330. One end of the starry sky interior trim 100 is connected to the transmission belt 340, and the other end of the starry sky interior trim 100 is connected to the first roller 310.

[0108] The first drive device 320 is connected to the first roller 310 and is used to drive the first roller 310 to rotate (for example, driving the first roller 310 to rotate clockwise in Figure 17), so that the starry sky interior decoration 100 is gradually wound around the first roller 310 to open the sunroof 210. The second drive device 350 is connected to the second roller 330 and is used to drive the second roller 330 to rotate (for example, driving the second roller 330 to rotate counterclockwise in Figure 17), so that the transmission belt 340 drives the starry sky interior decoration 100 to gradually disengage from the first roller 310 to close the sunroof 210.

[0109] By using a belt drive mechanism to drive the starry sky interior trim 100 to open and close the sunroof 210, the speed at which the starry sky interior trim 100 opens and closes the sunroof 210 can be well controlled, avoiding damage to the starry sky interior trim 100 caused by excessive speed in opening and closing the sunroof 210.

[0110] The type of transmission belt 340 is not unique. In some embodiments, the transmission belt 340 can be a V-belt, with V-grooves on the first reel 310 and the second reel 330 that mate with the V-belt. In other embodiments, the transmission belt 340 is a synchronous belt (i.e., a toothed belt), with toothed grooves on the first reel 310 and the second reel 330 that mate with the synchronous belt.

[0111] In some embodiments, as shown in FIG16, along the length direction X of the ceiling body 200, a first roller 310 and a second roller 330 are respectively disposed at the edges of opposite sides of the sunroof 210, and both the first roller 310 and the second roller 330 extend along the width direction Y of the ceiling body 200; there are two drive belts 340, along the width direction Y of the ceiling body 200, the two drive belts 340 are respectively disposed at the edges of opposite sides of the sunroof 210, one end of each drive belt 340 is wrapped around the end of the first roller 310, and the other end of each drive belt 340 is wrapped around the end of the second roller 330, and one end of the starry sky interior trim 100 is connected to both drive belts 340. This arrangement can prevent the starry sky interior trim 100 from tilting in the width direction Y of the ceiling body 200, thereby making the movement of the starry sky interior trim 100 more stable when opening or closing the sunroof 210.

[0112] In some embodiments, as shown in FIG16, the starry sky interior trim 100 can be connected to the transmission belt 340 via a connecting rod 450. The middle part of the connecting rod 450 (i.e., the part excluding both ends) is fixedly connected to the starry sky interior trim 100. The first end of the connecting rod 450 (the upper end in FIG16) is connected to one of the transmission belts 340, and the second end of the connecting rod 450 (the lower end in FIG16) is connected to the other transmission belt 340.

[0113] In some embodiments, the first drive device 320 and the second drive device 350 may both be motors.
