Description

Technical Field

[0001] The utility model relates to an automobile interior ceiling, in particular to an automobile interior starry sky ceiling. Background Art

[0002] The starry sky ceiling for car interiors is a starry sky component set on the ceiling body, which forms a light spot that can emit light on the front of the ceiling. The ceiling body includes a frame and fabric. The touch of the fabric is provided by polyurethane soft foam; and the appearance is reflected by the surface finishing layer. In order to achieve an aesthetic effect and ensure the light output effect, it is usually necessary to drill holes in the ceiling to install light-guiding components to form light spots. The light-guiding component is usually a plastic optical fiber, and the end of the optical fiber is flush with the ceiling fabric. If the end of the optical fiber is lower than the fabric, the light output will be blocked and the brightness will decrease. If the end of the optical fiber is higher than the fabric, touching the fabric will feel scratchy.

[0003] However, even if the optical fiber is flush with the fabric, there is still the problem of the optical fiber pricking the hand when pressing the fabric. Because when pressing or touching the fabric, if the force is a little too strong, the polyurethane soft foam will be compressed, and the end of the optical fiber will feel prickly. The optical fiber pricking the hand is a very bad experience and is an urgent problem that needs to be solved in the field of automotive interior starry sky ceilings. Utility Model Content

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A car interior starry sky ceiling, comprising:

[0006] The ceiling body comprises a frame and a fabric, wherein the fabric is a composite structure, and comprises a buffer layer and a surface finishing layer from top to bottom;

[0007] A starry sky component, the starry sky component comprises an optical machine and a light guide component, the light input end of the light guide component is connected to the optical machine, and the light output end of the light guide component is exposed from the front of the ceiling body to form a light spot;

[0008] The stitches surrounding the light spots are arranged on the fabric, penetrate the fabric in the thickness direction, and compress the thickness of the surface finishing layer.

[0009] Preferably, the surface finishing layer is knitted fabric or suede-like fabric.

[0010] Preferably, the buffer layer is polyurethane soft foam.

[0011] Preferably, the shape of the stitch is a circle or a cross.

[0012] Preferably, the light guiding component is a plastic optical fiber.

[0013] Preferably, the light guiding components are plastic optical fibers and light guiding elbows.

[0014] Furthermore, the light guide elbow is mounted on the ceiling body, the light output end of the light guide elbow is exposed from the ceiling body, the light input end of the light guide elbow is connected to the light output end of the plastic optical fiber, and the light input end of the plastic optical fiber is connected to the optical machine.

[0015] Beneficial Effects

[0016] (1) The stitches in the present invention will compress the buffer layer in the fabric. After the fabric is partially compressed, the optical fiber extending beyond the ceiling body is shortened and lower than the uncompressed fabric. When the fabric is touched by hand, the optical fiber will not scratch the hand, thereby improving the user's tactile experience. Moreover, after the fabric is compressed, the compression strength increases. Even if the light spot is pressed by hand, the amount of fabric sinking will be greatly reduced, so there will be no prickly feeling.

[0017] (2) The utility model uses stitches to form a circular or cross star pattern on the fabric, and then forms a light spot in the center of the pattern, which can produce a luminous effect of the cross star or circular pattern, bringing a different visual effect to the starry sky ceiling.

[0018] (3) The utility model is easy to manufacture. The fabric is recessed due to the stitches, and the recessed part provides the punching position. It is only necessary to punch a hole in the center of the recess, which is very easy to operate.

[0019] (4) Where there is no optical fiber, there can be traces, for example, using traces to form a three-dimensional pattern, and the traces should not be restricted to the presence of optical fiber. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the principles of the present invention; without departing from the spirit or scope of the present invention, those skilled in the art may also make various changes, modifications and substitutions. These changes, modifications and substitutions should all fall within the scope of protection of the present invention. In addition, it should be pointed out that, unless otherwise expressly specified and limited, the terms "installed / connected / connected" and the like in this document all refer to fixed connections, with the intention of connecting two elements to each other so that they work together, and are not used to indicate detachable connections. The details of the technical solution that are obvious to a person of ordinary skill in the art do not need to be elaborated, so they are not described in detail here.

[0027] Comparative Example 1

[0028] like Figure 1 As shown, in the manufacturing process of the traditional starry sky ceiling structure, it is necessary to punch holes in the ceiling body, penetrate the frame 11 and the fabric 12, and the light-guiding component is the optical fiber 2. The light-incoming end of the optical fiber 2 is connected to the optical machine (not shown), and the light-outgoing end is exposed from the front of the ceiling body, flush with the fabric 12, and fixed with glue on the back of the frame 11. The light-outgoing end of the optical fiber 2 must be flush with the surface of the fabric. If it exceeds the fabric too much, there will be obvious scratches; if it is too much lower than the fabric 12, the light emitted by the optical fiber 2 will be blocked by the fabric 12.

[0029] Even if the light-emitting end of the optical fiber 2 is trimmed to be substantially flush with the fabric 12, when the ceiling is pressed, the fabric 12 sinks, and the optical fiber 2 is glued and cannot retract, resulting in a prickly feeling.

[0030] Comparative Example 2

[0031] like Figure 2 As shown, in the manufacturing process of the traditional starry sky ceiling structure, it is necessary to punch holes in the ceiling body, penetrate the frame 11 and the fabric 12, install the light guide elbow 3 on the back of the frame 11, and fix them together with glue. The light output end of the light guide elbow 3 is exposed from the front of the ceiling body and is flush with the fabric 12. The light input end of the optical fiber 2 is connected to the optical machine (not shown), and the light output end is connected to the light input end of the light guide elbow 3 and fixed with optical glue.

[0032] Even if the light-emitting end of the light-guiding elbow 3 is trimmed to be substantially flush with the fabric 12 , when the ceiling is pressed, the fabric 12 sinks, and the light-guiding elbow 3 is glued and cannot retract, resulting in a prickly feeling.

[0033] Example 1

[0034] like Figure 3As shown, the starry sky ceiling of the present application includes a ceiling body and a starry sky component. The ceiling body includes a frame 11 and a fabric 12, the surface finishing layer of the fabric 12 is a knitted cloth or suede, and the buffer layer of the fabric 12 is a layer of polyurethane soft foam, which is set off under the knitted cloth or suede to provide a soft touch. The starry sky component includes an optical machine (not shown in the figure) and a light guide component, and the light guide component here is the optical fiber 2.

[0035] Compared with the control example 1, in this embodiment, the fabric around the light-emitting end of the optical fiber 2 has a sewing or embroidery stitch 121, and the stitches or embroidery threads penetrate the knitted fabric or suede and the polyurethane soft foam in the thickness direction, squeezing the thickness of the fabric to less than 50% of the original thickness, or even less than 20%.

[0036] During the production of the starry sky ceiling, it is necessary to punch holes in the ceiling body, penetrating the frame 11 and the fabric 12. With the stitches as a reference, the punching operation is much more convenient than the control example, because there are already recessed stitches 121 to provide the punching position, and it is only necessary to punch a hole in the center of the recessed stitches.

[0037] The light input end of the optical fiber 2 is connected to an optical machine (not shown), and the light output end passes through the ceiling body and is flush with the extruded fabric 12, or even slightly higher, so that the fabric does not touch the light output end of the optical fiber 2. The optical fiber 2 is fixed on the back of the frame 11 with glue.

[0038] Although the light-emitting end of the optical fiber 2 is slightly higher than the fabric 12 squeezed by the stitching or embroidery thread, when the ceiling body is pressed, the fabric 12 outside the stitches 121 sinks and does not touch the optical fiber 2, so there is no prickly feeling.

[0039] Example 2

[0040] like Figure 4 As shown, the starry sky ceiling of the present application includes a ceiling body and a starry sky component. The ceiling body includes a frame 11 and a fabric 12, the surface finishing layer of the fabric 12 is a knitted cloth or suede, and the buffer layer of the fabric 12 is a polyurethane soft foam, which is set off under the knitted cloth or suede to provide a soft touch. The starry sky component includes an optical machine (not shown in the figure) and a light guide component, and the light guide component here includes a plastic optical fiber 2 and a light guide elbow 3.

[0041] Compared with the control example 2, in this embodiment, the fabric around the light output end of the light guide elbow 3 has sewing or embroidery stitches, and the stitches or embroidery threads penetrate the knitted fabric or imitation suede and the polyurethane soft foam, squeezing the thickness of the fabric to less than 50% of the original thickness, or even less than 20%.

[0042] During the production of the starry sky ceiling, it is necessary to punch holes in the ceiling to penetrate the frame 11 and the fabric 12. The punching operation at this time is more convenient than the control example because there are already recessed stitches to provide the punching position, and it is only necessary to punch a hole in the center of the recess.

[0043] The light guide elbow 3 is installed on the back of the ceiling frame 11 and fixed together with glue. The light outlet end of the light guide elbow 3 is flush with the height of the fabric 12 after being squeezed by the sewing thread or embroidery thread, and can even be slightly higher, so that the fabric will not touch the light outlet end of the light guide elbow 3 when pressed. The light input end of the optical fiber 2 is connected to the optical machine (not shown), and the light output end is connected to the light input end of the light guide elbow 3 and fixed with optical glue.

[0044] Although the light emitting end of the light guide elbow 3 is slightly higher than the fabric 12 squeezed by the stitching or embroidery thread, when the ceiling is pressed, the fabric 12 outside the stitches 121 sinks but does not touch the light guide elbow 3, so there is no prickly feeling.

[0045] like Figure 5 As shown, the trace 121 surrounding the light spot can be in a circle shape, a cross star shape, or even other shapes. When the light engine is not turned on, it should not look too abrupt.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the implementation examples of the present invention. Any simple changes or modifications made to the above embodiments based on the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.
