Description

Technical Field

[0001] The present invention relates to the field of vehicle atmosphere lamps, and in particular to an atmosphere lamp assembly, a vehicle door panel and a vehicle. Background Art

[0002] As vehicles increasingly embrace personalized, flashy lighting effects, door panels, due to their large footprint, have become a popular choice for surface-emitting lighting. One current surface-emitting technology for vehicle door panels utilizes a woven light-conducting fiber layer within the door panel as a surface light source. For example, the ambient light assembly disclosed in patent CN114312556A comprises a base plate 1, a cushioning layer 2, a woven light-conducting fiber layer 4, a uniform light layer 5, and an outer cladding layer 6.

[0003] Vehicle door panels, as interior components, are often covered in leather for tactile feel, texture, and aesthetics, ensuring that all visible areas are made of leather. One of the characteristics of the leather covering process is that the leather, serving as the outer covering, must be stretched and tightened to ensure a smooth, wrinkle-free outer surface. This is not a problem for normal vehicle door panels, but when combined with vehicle door panels that utilize fiber-optic woven layer luminescence technology, problems arise:

[0004] First, as Figure 2 As shown, the current vehicle door panels using optical fiber woven layer luminescence technology also require a leather covering process. The outer covering layer 6 is wrapped around the outer surface of the door panel bottom plate along the edge of the bottom plate to the inner surface of the bottom plate. Since the outer covering layer 6 is in a stretched and taut state, the outer covering layer 6 near the edge of the bottom plate 1 will exert pressure on the optical fiber 4, causing the optical fiber 4 to cling to the bottom plate 1 and bend along the edge shape of the bottom plate, resulting in an excessively large change in the bending angle of the optical fiber, destroying the condition of total internal reflection of light propagation in the optical fiber, and thus causing light leakage from the optical fiber, affecting the overall optical performance;

[0005] Secondly, in addition to the light-guiding fiber woven layer, the surface of the vehicle door panel usually also includes other functional layers with specific functions. The number of layers varies from 1 to 3 according to needs. The overall thickness of the functional layer is relatively large. When the leather of the outer covering layer wraps the entire functional layer, it causes increased wrinkles at the edge corners where the two edges of the bottom plate intersect, affecting the wrapping effect. Summary of the Invention

[0006] To avoid the shortcomings of the background art, the present invention provides an ambient light assembly that can avoid excessive bending of light-guiding fibers and reduce the difficulty of the coating process.

[0009] Furthermore, the inner side surface has a strip-shaped protrusion, one side surface of the strip-shaped protrusion overlaps with one side surface of the second through-groove portion, and the light guide fiber contacts the strip-shaped protrusion after passing through the second through-groove portion.

[0010] Furthermore, the cross section of the strip-shaped protrusion is arc-shaped.

[0011] Furthermore, the functional layer includes a cushion layer and a reflective layer, the reflective layer is used to reflect the light emitted inwardly from the light-guiding fiber woven layer, and the cushion layer is arranged on the innermost side of the functional layer and is in contact with the outer surface of the base plate.

[0014] The present invention also provides a vehicle, comprising the vehicle door panel as described above.

[0015] The beneficial effect of the present invention is that by adding a through groove portion connecting the outer side and the inner side of the base plate, the optical fiber bundle end of the light-guiding fiber braided layer in the functional layer on the outer side of the base plate can pass through the through groove portion and be fixed on the inner side of the base plate. The outer covering layer does not need to wrap the entire functional layer, thereby avoiding excessive pressure and bending of the light-guiding fiber braided layer, thereby leaking light and affecting the overall optical performance, and at the same time reducing the difficulty of the covering process of the vehicle door panel.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] For example, see the attached Figure 1-7 An ambient light assembly is applied to a vehicle door panel and includes a base plate 100, a functional layer 200 and an outer covering layer 300. The bottom plate 100 includes an outer side surface 110 and an inner side surface 120. The outer side surface 110 of the bottom plate 100 has a side wall portion 130 and a receiving portion 140 surrounded by the side wall portion 130. The receiving portion 140 has a through groove portion 150 extending through the thickness of the bottom plate 100 at a position adjacent to the side wall portion 130. The functional layer 200 is provided on the surface of the accommodating portion 140. The functional layer 200 extends along the surface shape of the accommodating portion 140 and terminates in front of the side wall portion 130. The functional layer 200 includes a light-guiding fiber braided layer 220. The light-guiding fiber braided layer 220 includes warp and weft threads woven in an interlaced manner. The light-guiding fiber braided layer 220 is woven in a soft manner similar to cloth. At least one of the warp and weft threads is a light-guiding fiber. The light-inlet ends of the light-guiding fibers belonging to the same warp or weft threads are gathered into at least one optical fiber bundle end 221. The optical fiber bundle end 221 passes through the through-groove portion 150 and is fixed to the inner side surface 120 of the bottom plate 100. Each optical fiber bundle end 221 is connected to a light-emitting lamp head. Light emitted by the light-emitting lamp head enters from the light-inlet end of the light-guiding fiber and is emitted outward from the side of the light-guiding fiber. The final appearance to the naked eye is that the light-guiding fiber braided layer 220 has a surface light-emitting effect. The outer covering layer 300 covers the entire outer side surface 110 of the base plate 100 and wraps back toward the inner side surface 120 of the base plate 100 at the edge of the base plate 100 to cover part of the inner side surface 120 of the base plate 100 and part of the light-guiding fiber; the outer covering layer 300 has a preset light-transmitting pattern portion. In this embodiment, the outer covering layer 300 is preferably a leather layer with a hollow pattern, and the light emitted by the light-guiding fiber woven layer 220 can be emitted to the outside from the light-transmitting pattern portion.

[0026] In the ambient light assembly of this embodiment, a through groove portion 150 connecting the outer side surface 110 and the inner side surface 120 is added to the base plate 100, so that the optical fiber bundle end 221 of the optical fiber braided layer 220 in the functional layer 200 of the outer side surface 110 of the base plate 100 can pass through the through groove portion 150 and be fixed to the inner side surface 120 of the base plate 100. The outer covering layer 300 does not need to wrap the entire functional layer 200, so as to avoid excessive pressure and bending of the optical fiber braided layer 220, thereby leaking light and affecting the overall optical performance, and at the same time reduces the difficulty of the covering process of the vehicle door panel.

[0027] In order to make the appearance of the vehicle door panel smooth, in this embodiment, the height of the side wall portion 130 relative to the accommodating portion 140 is equal to the thickness of the functional layer 200. The overall thickness of the functional layer 200 can be determined first, and then the height of the side wall portion 130 relative to the accommodating portion 140 can be determined. When the outer covering layer 300 covers the entire outer side surface 110 of the covering base plate 100, the appearance at the position of the side wall portion 130 has no concave or convex line defects.

[0028] In this embodiment, the through-groove portion 150 includes a first through-groove 151 and a second through-groove 152. The specific shape of the first through-groove 151 does not matter as long as the inscribed circle diameter of the first through-groove 151 is greater than the outer diameter of the optical fiber bundle end 221, so that the optical fiber bundle end 221 can easily pass through the through-groove portion 150; the second through-groove 152 is connected to the first through-groove 151 and is narrow and long as a whole. The optical fiber bundle end 221 is formed by the convergence of multiple optical fibers. Since the convergence cannot be completed on the outer side surface 110 of the base plate 100 otherwise it will affect the appearance, the convergence can only be completed on the inner side surface 120 of the base plate 100. The optical fibers in the optical fiber braided layer 220 are arranged side by side, so a narrow and long second through-groove 152 is required for the optical fibers to pass through; during assembly, the optical fiber bundle end 221 is first passed through the first through-groove 151, and then the optical fibers connected to the optical fiber bundle end 221 are flatly spread out in the second through-groove 152.

[0029] Considering that the thickness of the base plate 100 will not be too thick, in order to prevent the bending angle of the light guide fiber from being too large after passing through the through groove portion 150, in this embodiment, the inner side surface 120 of the base plate 100 has a strip-shaped protrusion 160 with an arc-shaped cross-section. One side of the strip-shaped protrusion 160 coincides with one side of the second through groove 152 portion 150, and the light guide fiber contacts the strip-shaped protrusion 160 after passing through the second through groove 152 portion 150.

[0030] The functional layer 200 includes multiple layers with different functions. Generally speaking, the more functions the functional layer 200 has, the thicker the overall thickness of the functional layer 200 is, which makes it more difficult to use traditional coating processes. According to actual needs, in this embodiment, the functional layer 200 includes a cushioning layer 210 and a reflective layer; the cushioning layer 210 is arranged on the innermost side of the functional layer 200 and fits with the outer surface of the base plate 100, which can play a buffering role and has good safety when the user accidentally collides. At the same time, when the user touches the atmosphere light assembly, it provides a soft and resilient touch to improve the user experience. In this embodiment, the cushioning layer 210 is preferably a sponge layer; the reflective layer is mainly used to reflect the light emitted inward by the light-guiding fiber woven layer 220. Since the side of the light-guiding fiber is 360 degrees around the light-emitting layer, , that is, nearly half of the light is directed inward. Adding a reflective layer can reflect this part of the light, which can significantly improve the brightness of the ambient light assembly; the reflective layer can be in the form of a part, such as using a white soft light cloth and a light-guiding fiber woven layer 220; it can also be attached to the soft cushion layer 210, such as spraying white reflective paint on the outer surface of the soft cushion layer 210; this embodiment prefers the solution of spraying white paint on the outer surface of the soft cushion layer 210. The spraying process of this solution is simple, and no additional parts are added, thereby reducing costs.
