Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle interior design, and in particular relates to a vehicle headliner interior structure, a vehicle interior assembly having the same structure, and a vehicle. Background Technology
[0002] In the design and development of vehicle interiors, starlight roof models have become increasingly popular to enhance the sense of luxury, improve the ambiance, and provide personalized customization options. However, existing starlight roof structures, such as those shown below... Figure 1-2 The structural diagram shown currently has the following shortcomings: (1) The process implementation route is complicated: it requires sequential steps such as forming the substrate layer 1a, forming the substrate layer 1a and the fabric layer 2a together, drilling multiple through holes 3a on the composite structure formed by the substrate layer 1a and the fabric layer 2a, and manually embedding the light source 4a in each through hole 3a. Compared with automated production, this restricts the production efficiency of the starry sky roof structure. (2) Insufficient light effect: The existing starry sky roof structure forms a dot matrix pattern through the light transmission through the through hole 3a when it is working, and the light effect is only prominent at night. It cannot present dynamic light effects (such as meteor shower, dynamic water flow, etc.), which is not conducive to meeting the user's customized needs. (3) Insufficient structural strength: The existing starry sky roof structure requires multiple through holes 3a to be drilled in the composite structure formed by the substrate layer 1a and the fabric layer 2a during manufacturing, which reduces the strength of the substrate layer 1a. Utility Model Content
[0003] In view of the above, the purpose of this utility model is to provide a vehicle roof interior structure and a vehicle interior assembly having the same, and a vehicle, to solve at least one of the above technical problems.
[0004] To achieve the above-mentioned technical objectives, the first aspect of this utility model provides a vehicle roof interior structure, the interior structure comprising: A substrate layer for connecting to the vehicle body, the substrate layer having a light source mounting port for mounting a light source; A fabric layer includes a fabric layer body and a light-emitting element. The fabric layer body is disposed on the surface of the substrate layer that is close to the cockpit. The light-emitting element is integrated into the fabric layer body. The fabric layer body is used to provide the appearance. The light-emitting body is either photoluminescent or electroluminescent. When the light source is photoluminescent, the light source is used to absorb the emitted light from the light source and emit visible light that can illuminate the cockpit; When the light-emitting body is an electroluminescent type, the light-emitting body is used to conduct and transmit the emitted light from the light source.
[0005] In one embodiment, the light emitter has a pattern formed on the fabric layer body, the pattern including at least one of a straight line segment and a curved segment.
[0006] In one embodiment, the light emitter includes light-emitting fibers, which are electroluminescent.
[0007] In one embodiment, the diameter of the luminescent fiber is 0.2 mm to 1.0 mm.
[0008] In one embodiment, the wavelength of the visible light emitted by the light source is greater than the wavelength of the emitted light from the light source.
[0009] In one embodiment, the fabric layer body comprises polyester filaments.
[0010] In one embodiment, the light-emitting element is integrated with the fabric layer body through a knitting process.
[0011] In one embodiment, the substrate layer is a multi-layer composite structure, comprising a substrate body layer, a heat insulation layer, and a sound-absorbing layer.
[0012] The second aspect of this utility model provides a vehicle interior assembly, including the vehicle headliner interior structure as described in the above technical solution.
[0013] The third aspect of this utility model provides a vehicle, including the vehicle interior assembly as described in the above technical solution.
[0014] By adopting the above technical solution, this utility model has the following beneficial effects: (1) The process is simple and the production efficiency is high: By integrating the light source with the fabric layer to form a new fabric layer, compared with the cumbersome operation of separately manufacturing the substrate layer and fabric layer, then opening multiple through holes on the composite substrate layer and fabric layer and manually threading the light source in each through hole, this can simplify the production process of the starry sky structure. On the other hand, it can improve the production efficiency of the starry sky structure by 80%, reduce the unit cost by about 40%, save the part development cost by 30%, and shorten the development cycle by 20%. (2) Outstanding and rich light effects: Since the improved light effects are linear, compared with the previous dot matrix, the light effects are not only outstanding, but also help to meet the personalized customization needs of users, such as dynamic light effects (meteor shower, dynamic water flow, etc.). (3) High structural strength: Since there is no need to open multiple through holes in the base material layer and fabric layer, this helps to improve the strength of the interior structure, thereby improving the safety of the vehicle.

[0026] In the design and development of vehicle interiors, starlight roof models have become increasingly popular to enhance the sense of luxury, improve the ambiance, and provide personalized customization options. However, existing starlight roof structures, such as those shown below... Figure 1-2 The structural diagram shown currently has the following shortcomings: (1) The process implementation route is complicated: it requires sequential steps such as forming the substrate layer 1a, forming the substrate layer 1a and the fabric layer 2a together, drilling multiple through holes 3a on the composite structure formed by the substrate layer 1a and the fabric layer 2a, and manually embedding the light source 4a in each through hole 3a. Compared with automated production, this restricts the production efficiency of the starry sky roof structure. (2) Insufficient light effect: The existing starry sky roof structure forms a dot matrix pattern through the light transmission through the through hole 3a when it is working, and the light effect is only prominent at night. It cannot present dynamic light effects (such as meteor shower, dynamic water flow, etc.), which is not conducive to meeting the user's customized needs. (3) Insufficient structural strength: The existing starry sky roof structure requires multiple through holes 3a to be drilled in the composite structure formed by the substrate layer 1a and the fabric layer 2a during manufacturing, which reduces the strength of the substrate layer 1a.
[0027] In order to solve the above-mentioned technical problems in the existing technology, it is necessary to improve or optimize the existing starry sky roof structure to provide users with personalized customization options.
[0028] Example 1 Please see Figure 3 , Figure 4 An embodiment of the first aspect of this utility model provides a vehicle roof interior structure 100 for installation on the top of a vehicle, such as in the area where the roof of the vehicle is located, to enhance the visual effect and sense of luxury of the vehicle.
[0029] For example, the interior structure 100 includes a substrate layer 10 and a fabric layer 20. The substrate layer 10 is used to connect to the vehicle body, such as the inner surface area of the vehicle roof, and the substrate layer 10 is provided with a light source mounting port 11 for mounting a light source. It is worth noting that the light source referred to here is a light source capable of adjusting brightness and color, such as LED light sources used in vehicles to create a starry sky ceiling effect.
[0030] Exemplarily, the substrate layer 10 has a multi-layer composite structure, and the light source mounting port 11 is formed at one end of the substrate layer 10. Specifically, the substrate layer 10 includes a substrate body layer, a heat insulation layer, and a sound absorption layer, but is not limited thereto. The substrate body layer can be composed of polyethylene fiber or polypropylene fiber; the heat insulation layer can be composed of aluminum foil heat insulation cotton; and the sound absorption layer can be composed of sound absorption cotton. Preferably, the heat insulation layer and the sound absorption layer are located within the substrate body layer.
[0031] Exemplarily, the fabric layer 20 includes a fabric layer body 21 and a light-emitting element 22. The fabric layer body 21 provides the appearance and is attached to the surface of the substrate layer 10 near the cabin. Viewed vertically, the fabric layer body 21 is located at the bottom surface of the substrate layer 10. The light-emitting element 22 is integrated onto the fabric layer body 21. It is worth noting that the light-emitting element 22 is electroluminescent, used to conduct and transmit emitted light from a light source, such as light-guiding structures like luminescent fiber filaments that beautify the vehicle roof by guiding the light beam emitted by the light source. Preferably, the diameter of the luminescent fiber filament is 0.2mm to 1.0mm, such as 0.2mm, 0.5mm, or 1.0mm. This not only facilitates control of the brightness of the light-emitting element 22 but also helps reduce the manufacturing cost of the interior structure 100.
[0032] For example, to meet users' personalized customization needs, the light-emitting body 22 forms a pattern on the fabric layer body 21. Specifically, the pattern formed by the light-emitting body 22 on the fabric layer body 21 includes at least one of straight line segments and curved line segments, such as a stepped pattern composed of five straight line segments, a wave-shaped pattern composed of one curved line segment, and a double-ring pattern composed of two curved line segments. In this way, by illuminating the light-emitting bodies 22 of different shapes on the fabric layer body 21 to present light effects corresponding to the patterns, it is beneficial to enhance the atmosphere and bring a pleasant mood to the user.
[0033] Furthermore, the color of the light-emitting element 22 is the same as or close to the color of the fabric layer body 21. Thus, when the light-emitting element 22 is not illuminated, it is not easily recognizable by the user during the day, and the fabric layer body 21 effectively conceals it, preventing it from appearing unusual. However, when the light-emitting element 22 is illuminated, it is easily recognizable by the light. This enhances the sense of mystery and surprise of the interior structure 100.
[0034] Furthermore, in order to ensure the connection or integral molding of the light-emitting body 22 with the fabric layer body 21 to achieve the integration of the two, the fabric layer body 21 includes polyester filaments, such as low-elastic polyester filaments, profiled polyester filaments, and other translucent polyester fibers, which is beneficial for achieving efficient manufacturing through automated production.
[0035] Furthermore, in order to achieve the connection or integral molding of the light-emitting body 22 and the fabric layer body 21, the light-emitting body 22 is integrated with the fabric layer body 21 through a knitting process, such as weft knitting. This helps to ensure the adhesion and appearance of the fabric layer 20 on the substrate layer 10, such as the flatness of the fabric layer 20 when it is laid flat on the outer surface of the substrate layer 10.
[0036] In summary, this utility model, by integrating the light-emitting element 22 with the fabric layer body 21 to form a new fabric layer 20, not only avoids the cumbersome operation of opening multiple through holes 3a on the conventional substrate layer 1a and fabric layer 2a and manually threading the light-emitting element 4a into each through hole 3a, but also helps to meet the personalized customization needs of users because the improved light effect is linear.
[0037] Example 2 The second aspect of this utility model also provides a vehicle roof interior structure. Most of the features of this interior structure are the same as those of the interior structure 100 of the first embodiment. The difference is that the light-emitting element of the interior structure of this second embodiment is structurally different from the light-emitting element 22 of the interior structure 100 of the first embodiment. The following is a detailed description.
[0038] In Embodiment 2, the light-emitting body is a photoluminescent type, which is used to absorb the emitted light from the light source and emit visible light that can illuminate the cabin. Examples include light-emitting structures such as plastic luminescent fibers that absorb external light beams (such as natural sunlight or light from in-vehicle sources) and emit visible light. The core principle is that under external conditions (such as light), photons are generated through electron transitions in the luminescent material, which then emit visible light. This also addresses the shortcomings of existing technologies.
[0039] It is worth mentioning that the visible light mentioned here refers to light waves that can be perceived by the human eye, such as light waves ranging from red to violet, and these light waves are emitted by non-radioactive materials to ensure compliance with environmental protection and safety requirements.
[0040] Furthermore, the wavelength of the visible light emitted by the luminous body is greater than the wavelength of the illumination light from the light source. This helps to ensure the scattering effect and penetrating power of the visible light emitted by the luminous body, so as to present a better starry sky effect.
[0041] Example 3 A third aspect of this utility model provides a vehicle interior assembly that includes a vehicle headliner interior structure as described in any of the above embodiments.
[0042] Furthermore, the vehicle interior assembly also includes a light source. Specifically, the light source is installed at the light source mounting port 11 of the substrate layer 10, and it is used to emit light. Preferably, the light source is an LED light source electrically connected to the vehicle body wiring harness. This is beneficial for giving the vehicle interior assembly a more visually impactful feature.
[0043] Example 4 An embodiment of the fourth aspect of this utility model provides a vehicle that includes a vehicle interior assembly as described in Embodiment 3, which is beneficial to enhancing the vehicle's appeal and luxury.
[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
