Abstract
Description
Technical Field
[0001] The present application belongs to the field of automobile interior decoration, and specifically relates to an automobile interior ceiling. Background Art
[0002] There are two common fabrics used for car interior ceilings: knitted fabrics and needle-punched non-woven fabrics. Knitted fabrics are very thin and usually need to be used with polyurethane soft foam for mid- to high-end models; needle-punched non-woven fabrics have a certain thickness and can usually be used directly for mid- to low-end models. In addition, there are also suede-like fabrics for high-end models, and PVC leather fabrics for taxis.
[0003] Usually, knitted fabrics have certain patterns, but the patterns cannot be seen from a distance. Non-woven fabrics also have printed patterns, but they are usually printed to create the effect of knitted fabrics, and the patterns cannot be seen from a distance.
[0004] In recent years, high-end models have begun to have embroidered ceilings. The exquisite patterns formed by embroidery give the models a more upscale texture. However, embroidery is to cover the blocks of the fabric body with embroidery threads of specific colors to form embroidered patterns, so it requires a lot of stitches and is very expensive.
[0005] At present, competition in the automotive industry is becoming increasingly fierce, and many car models are pursuing low-cost innovative solutions. This is also one of the reasons why our technical solution came out. Utility Model Content
[0006] A car interior ceiling comprises a ceiling frame and a fabric adhered to the ceiling frame, wherein the fabric comprises a knitted fabric and a filler composited with the knitted fabric, and the fabric is provided with stitches which compress the knitted fabric and the filler, wherein the stitches on one side of the filler are adhered to the ceiling frame, and the stitches on one side of the knitted fabric are recessed below the plane of the knitted fabric.
[0007] Preferably, the stitches compress the knitted fabric and the filling body to 50% or less of their original thickness.
[0008] Preferably, the color of the stitches is the same as or close to the color of the knitted fabric.
[0009] Preferably, the thread used for the stitches is a suture thread or an embroidery thread, and the suture thread or the embroidery thread is a matte thread.
[0010] Preferably, the thread used for the stitches is a thick thread and is formed by sewing once.
[0011] Preferably, the thread used for the stitches is a thin thread and is formed by multiple stitching.
[0012] Furthermore, the needle holes of the multiple embroidery stitches do not overlap.
[0013] Preferably, there are two or more stitches, which are close to each other and have similar shapes, and the distance between two adjacent stitches is 0.5-3 times the thickness of the fabric.
[0014] Preferably, there are a plurality of traces, including two traces as boundaries and a filling trace located between the two boundaries and not in the same direction as the boundaries. Beneficial Effects
[0015] 1. The embroidery in the prior art uses threads with different colors to form patterns, and the patterns have colors different from the main body. The main technical effect of the solution of the present application lies in the convex and concave feeling. The color of the stitches is the same as or similar to that of the knitted fabric and does not affect the convex and concave feeling. It is a solution with an effect different from that of ordinary embroidery.
[0016] 2. Ceiling fabrics are usually not reflective. This application uses stitches formed by matte lines, which maintain the convex and concave feeling while the stitches themselves have a better hiding effect.
[0017] 3. In this application, the stitches are made of thick thread, which can have higher strength and form stitches in one go; thin thread is another option, especially through the multi-embroidery method, which can avoid the thread ends being too obvious when starting and closing the needle.
[0018] 4. When the stitches of this application are made of fine thread, the needle holes do not overlap, because overlapping needle holes will make the stitches of the stitches particularly eye-catching. Even if the stitches are similar in color to the knitted fabric, the eye-catching needle holes will destroy the three-dimensional effect, which is not what we want. Therefore, staggering the needle holes of multiple embroidery to avoid the needle holes being too eye-catching is a solution to avoid the needle holes from overshadowing the main feature.
[0019] 5. The color of the stitches in this application can be the same or similar to that of the knitted fabric, or it can form a clear contrast with the knitted fabric. For stitches with the same or similar colors, the sense of lines is not obvious, and the sense of convexity and concavity is better. For stitches with obvious color contrast, the sense of convexity and concavity is no longer the most eye-catching, but the sense of lines is more obvious.
[0020] 6. The fabric in this application adopts a structure in which knitted fabric and filler are compounded into one body, and the thickness generally ranges from 2-6mm, which can bring a soft touch, so it is used in mid-to-high-end models. The filler, such as polyurethane soft foam, has a large compressibility, so the thickness of the fabric in the stitching area is greatly reduced, becoming less than 50% of the original thickness, or even less than 20%. When the fabric is attached to the ceiling frame, the back side is attached to the ceiling frame, so the stitches pull down the knitted fabric, which is sunken below the plane of the knitted fabric, forming a stitch with a distinct sense of depression.
[0021] 7. The concave lines formed by a single concave stitch will appear thin. This application uses multiple stitches close to each other to form a concave belt with a certain width, making the pattern more expressive. If the width between the two stitches is too small, no obvious effect will be produced. If the width is too large, the filling body will rebound and the concave feeling will disappear. Therefore, the distance between the two stitches can be limited to 0.5-3 times the thickness of the fabric.
[0022] 8. For situations where a wider concave band is required, the present application adopts a solution of distributing stitches of a certain width between two stitches, which can prevent the filling body from rebounding and causing the concave feeling to disappear. These stitches located between the two stitches, unlike ordinary embroidery, have a coverage rate of less than 30% to reduce the number of embroidery needles and reduce costs.
[0023] 9. Because the stitching or embroidery threads on the stitching are hidden in the valley of the surface lines of the fabric, the chance of being worn or scratched is greatly reduced, so the fabric does not need to be protected from scratches like traditional embroidery fabrics.
[0024] 10. The stitching or embroidery thread runs through the fabric, including the knitted fabric and the filling, so even if the filling fails and loses strength, the knitted fabric will be fixed to the frame through the stitches, reducing the risk of large-scale delamination.

[0032] Comparative Example 1
[0033] like Figure 1 As shown in FIG. 1 , a common ceiling generally includes a ceiling frame 1 and a fabric 2 attached to the ceiling frame. The fabric 2 generally includes a knitted fabric 21 and a filler 22, such as Figure 1 and Figure 2 shown.
[0034] The knitted fabric 21 provides an appearance, and the filling body 22 provides a soft touch and has certain sound absorption and heat insulation effects.
[0035] Knitted fabrics have a certain pattern due to their weaving structure, but it cannot be seen from a distance.
[0036] Therefore, the current car interior ceiling is very monotonous.
[0037] Comparative Example 2
[0038] The embroidered ceiling is a breakthrough from the traditional ceiling. Through embroidery, exquisite embroidery patterns are formed on the ceiling, which greatly enhances the sense of luxury. The main part is formed by flat stitches, and some flat stitches are used as decoration. Different colors of embroidery threads form distinct color blocks.
[0039] There are several problems with embroidered ceilings: 1. Embroidery is a relatively expensive process. A seemingly small pattern may require hundreds of thousands of stitches, which is inefficient and costly. 2. Because the embroidery thread of the flat needle will exert a large pulling force on the fabric, a harder backing paper needs to be used on the back, and the backing paper will eventually remain in the embroidered fabric. 3. Although the embroidery has a certain three-dimensional sense, it is mainly formed by the flat needle and has nothing to do with the filler, so the three-dimensional sense is not too strong. 4. The embroidery thread will be higher than the main body of the fabric and is easy to wear. 5. The embroidery thread does not pass through the filler, and the surface suede fabric and the frame are separated by the filler. If polyurethane soft foam is used as the filler, after about 10 years of hydrolysis, the polyurethane soft foam will shatter, causing the fabric to fall off.
[0040] Therefore, embroidered ceilings only appear on very high-end models, and are not suitable for ordinary mid-to-high-end models. Example
[0041] Fabric structure Figure 3 As shown, in addition to the knitted fabric 21 and the filling body 22, it also includes stitches 23 for compressing the knitted fabric 21 and the filling body 22 to a certain thickness.
[0042] like Figure 3 As shown, after the fabric 2 with the stitches 23 is pasted onto the ceiling frame 1, the back side of the stitches 23 is pasted onto the ceiling frame 1, and an obvious depression is formed on the front side of the stitches 23, thereby forming a three-dimensional effect with uneven contours.
[0043] Because the stitching 23 is hidden in the depression, there is basically no problem of stitching fraying.
[0044] The color of the stitch 23 here can be the same as or similar to that of the fabric 2 to achieve a better sense of unity, or it can be quite different from the fabric 2 to make the line sense more obvious.
[0045] The stitches 23 can be formed by quilting with a sewing machine or by embroidery with an embroidery machine.
[0046] The advantage of quilting is that it can be completed in one go, with high efficiency and low cost.
[0047] Embroidery usually requires the use of flat stitch three times or flat stitch five times, which is much less efficient. However, the thin embroidery thread can better hide the traces of stitching and closing stitches compared to the stitches of three times or five times.
[0048] For the three-time or five-time embroidery techniques, the needle holes of multiple embroidery can be overlapped to create a quilting effect, or the needle holes can be staggered to make the overall feel of the lines better.
[0049] For multiple embroidery lines with staggered needle holes, if the color of the stitches 23 is the same as that of the knitted fabric 21, the presence of the stitches 23 can be reduced, making the convex and concave feeling purer.
[0050] Flat needles can better hide the needle eye and make the stitches 23 look more continuous. However, the solution of the present application is to reduce the number of needles and reduce costs, so even if flat needles are used, the width is very small, the stitches are very long, and the coverage rate is very low.
[0051] The commonly used embroidery thread has a certain degree of reflectivity, while the fabric 2 is usually non-reflective, so using matte or matte embroidery thread is a more preferred solution.
[0052] Of course, you can also use a flat needle with a smaller width to form a line of a certain width, making the line look more continuous and better overall. Be careful not to make the line too wide to ensure that the number of stitches will not increase too much, and the line should be narrow to ensure that the stitch 23 is obviously sunken and protected by the fabrics on both sides, so that the embroidery thread is not easily worn. Example
[0053] Although narrow lines formed by quilting or embroidery can achieve a certain three-dimensional effect, sometimes wider lines are needed. If wide lines are formed by flat stitch, it will return to the old way of ordinary embroidery, which will greatly reduce efficiency and increase costs.
[0054] Fabric structure Figure 4 As shown, it is a better solution to use two stitches 23 separated by a certain distance to achieve wide lines. The distance between the two stitches 23 should not be too large, otherwise the filling body 22 in the middle will rebound severely, forming an obvious bulge, which does not look like a whole line. For this reason, the width between the two stitches 23 should not exceed 3 times the thickness of the fabric 2, preferably 1-2 times.
[0055] like Figure 5 ,6 As shown, if you need to achieve lines that are more than 3 times the thickness of the fabric, there are two methods. One is to use multiple stitches 23 with relatively consistent shape contours, and the spacing between adjacent stitches 23 is controlled to be less than 3 times the thickness of the fabric 2. The other is to use smooth stitches 23 on the outer border and use other stitches 23 within the border, such as zigzag shapes, lattice shapes, or other shapes that bend back and forth, or even some traditional Chinese patterns. The stitches 23 within these boundaries play a certain filling role, but the number of needles should be minimized as much as possible, and the rebound of the filling body should be avoided. Flat needles are also a solution to form stitches, but flat needles require more needles and cover a larger area, which is a bit similar to traditional embroidery solutions and is not a preferred choice. However, even if flat needles are used, the width of the flat needles can be smaller, such as 2-5mm, which is still significantly different from traditional embroidery. On the one hand, the embroidery area accounts for a small proportion, and on the other hand, the stitch width is small, and the three-dimensional sense or convex and concave sense is more obvious compared to the color formed by the embroidery thread.
[0056] Regarding the filler 22, the most common one is polyurethane sponge, but polyurethane sponge has the problem of hydrolysis. In fact, 3D mesh is also a relatively good filler material. In addition, there are also cases where needle-punched non-woven fabrics are compounded on the back of knitted fabrics as the filler 22. As long as it has a certain thickness and elasticity and can achieve a soft touch of the fabric 2, it may be used as the filler 22.
[0057] In the solution of the present application, the stitch 23 runs through the entire fabric 2 and is pasted to the ceiling frame 1. Even if a polyurethane sponge is used, the problem of fabric delamination caused by the hydrolysis of the polyurethane sponge can be alleviated, and the stitch 23 will play a certain role in fixing the fabric 2.
[0058] Because the stitches 23 penetrate the fabric 2 and compress the filling body 22, after the fabric 2 is attached to the ceiling frame 1, the stitches 23 are deeply sunken therein, forming a good three-dimensional effect. In addition, the stitches 23 fall at the bottom of the lines, reducing their presence, not attracting attention, and not easily worn.
