Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile interior decoration, in particular to an interior decoration upper body and a door panel, and an automobile. Background Art
[0002] As a kind of decoration, interior decoration beautifies the internal structure of the car and improves the comfort and experience of the car users, which makes it more and more important in the current automobile production. When the interior decoration such as fabric is covered on some structures such as door panels, if the structure is 3D, the fabric as a plane will inevitably produce wrinkles at the intersection of the three sides of the structure. The wrinkles not only affect the appearance, but also will interfere with the assembly of the structure with other structures. Therefore, solving the wrinkles is a problem that technicians in this field often face.
[0003] In Chinese patent CN220096284U (door interior panel upper body and door panel), in order to solve the above-mentioned wrinkle problem, after the fabric covers the upper body frame and the surface of the water-cut bracket, it is designed to sew the fabric at the upper body frame A with a blind stitch, and at the same time, a wire groove is set at this position of the upper body frame to accommodate the blind stitch, so that the fabric at this position is smooth and flat, thereby achieving the purpose of avoiding wrinkles.
[0004] However, in actual operation, since the above-mentioned hidden stitching is manually operated, there will inevitably be deviations when sewing the fabric at the upper body frame A. The final hidden stitching is not truly contained in the wire groove, making the surface at the hidden stitching higher than other surfaces, thereby making the entire body of the door interior trim panel unqualified, reducing the product yield and increasing production costs. Utility Model Content
[0005] The utility model aims to provide an interior decoration upper body and a door panel to solve the problem of low yield rate of products in the prior art.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an interior decoration upper body, including an upper body frame, a water-cut bracket and a fabric, the water-cut bracket is located below the upper body frame, the end of the upper body frame is bent downward and is located on the outside of the end of the water-cut bracket, the fabric covers the surface of the upper body frame and is folded to the back of the upper body frame, and the upper body frame is connected and fixed to the water-cut bracket.
[0007] The principle of this solution is: in Chinese patent CN220096284U, the upper body frame and the water-cut bracket are first fixed together, and then the fabric is covered on the surface of the upper body frame and the water-cut bracket, and the effect presented is full coverage, that is, the fabric covers three surfaces; while in this solution, the fabric is first covered on the surface of the upper body frame, and then the upper body frame and the water-cut bracket are fixed together, and the effect presented is half coverage, that is, the fabric only covers two surfaces of the upper body frame. At this time, there is no hidden seam, and there is no need to set a wire groove at A of the upper body frame (refer to the attached figure of CN220096284U), and because the position of the water-cut bracket on the door panel is located in a place that is invisible to the car user, its surface does not need to be covered with a layer of decorative fabric.
[0008] The beneficial effects of this program are:
[0009] 1. Avoid the interference problem caused by the surface protrusion caused by the blind seam, and improve the product yield;
[0010] 2. It eliminates the process of manual suturing of blind stitches, thus simplifying the production process;
[0011] 3. The wire groove on the upper body frame is cancelled, reducing the complexity of processing;
[0012] 4. It saves the surface material of the water-cut bracket and reduces the cost of raw materials.
[0013] The structure involved in this solution was originally implemented in response to customer requirements to fully wrap the surface of the upper body frame and the water-cut bracket combination with fabric to achieve the purpose of aesthetics. Therefore, the general design idea of the technicians will follow the customer's requirements to implement full wrapping. When full wrapping has problems such as wrinkles, they will find ways to solve the problem of wrinkles, thus producing solutions such as those in the background technology. The technicians of this solution analyzed the customer's ultimate goal - beauty. On the premise of ensuring the beauty of the visible surface of the car user, the technicians jumped out of the inherent thinking of full wrapping and adopted a half-wrapping method to achieve the same aesthetic purpose as full wrapping, without the wrinkle problem caused by full wrapping. At the same time, compared with the solution in the background technology, the beneficial effects listed above are obtained, so this solution is more practical.

[0034] The following is further described in detail through specific implementation methods:
[0035] The reference numerals in the drawings of the specification include: an upper body frame 1 , a water cutting bracket 2 , a positioning block 11 , and a connecting portion 21 .
[0036] Example 1
[0037] Basically as attached Figure 1 Shown is: an interior decoration upper body, including an upper body frame 1, a water-cut bracket 2 and a fabric (the fabric is not shown in the figure), the water-cut bracket is located below the upper body frame, the end of the upper body frame is bent downward and is located on the outside of the end of the water-cut bracket, the fabric covers the surface of the upper body frame 1 and is folded to the back of the upper body frame, and the upper body frame 1 is welded and fixed to the water-cut bracket 2.
[0038] In actual application, in Chinese patent CN220096284U, the upper body frame 1 and the water-cut bracket 2 are first fixed together, and then the fabric is covered on the surface of the upper body frame 1 and the water-cut bracket 2, and the effect presented is that the fabric covers three surfaces; while in this solution, the fabric is first covered on the surface of the upper body frame 1, and then the upper body frame 1 and the water-cut bracket 2 are fixed together, and the effect presented is that the fabric only covers two surfaces of the upper body frame 1, and at this time, there is no hidden seam, and there is no need to set a wire groove at A of the upper body frame 1 (refer to the attached figure of CN220096284U), and because the position of the water-cut bracket 2 on the door panel is located in a place that the car user cannot see, its surface does not need to be covered with a layer of fabric for decoration. Therefore, this solution not only avoids the interference problem caused by the surface protrusion caused by the hidden seam, improves the product yield, but also saves the process of manually sewing the hidden seam, simplifies the production process, and cancels the wire groove on the upper body frame 1, reduces the complexity of processing, and finally saves the fabric on the surface of the water-cut bracket 2, reducing the cost of raw materials.
[0039] The fabric covers the surface of the upper body frame 1, and in order to make the two relatively fixed and not displaced, the present embodiment adopts a bonding method. As for whether to adopt partial bonding or full bonding (that is, bonding is performed wherever the fabric contacts the surface of the upper body frame 1), no excessive restrictions are made here. As an example, the present embodiment adopts a full bonding method to ensure that the fabric and the upper body frame can fit smoothly, firmly, and beautifully.
[0040] In addition, as for the adhesive used to bond the fabric to the upper body frame 1, as an example, this embodiment uses glue, and the glue can be applied to the back of the fabric and / or the surface of the upper body frame 1. When applying glue to the back of the fabric, the glue should not be applied to the entire back of the fabric, because when the fabric is bonded to the upper body frame 1, there will generally be excess glue overflowing, and excessive overflowing glue may form solids and hinder the bonding of the water-cut bracket 2 and the upper body frame 1. For this reason, as an example, this embodiment designs the edge of the glue layer to be 4-6mm away from the edge of the fabric, so that this blank distance can be used to absorb excess glue.
[0041] In practical applications, when the fabric is folded to the back of the upper body frame 1, the fabric will also be fixed to the back of the upper body frame 1 by bonding. At the same time, the width of the fabric folded to the back should not be too long to avoid the fabric from contacting certain parts on the back (such as Figure 2 As an example, according to the structure of the back of the upper body frame 1, the width of the fabric folded to the back of the upper body frame 1 is set to 6-8mm. This design will not cause interference between the fabric and the back parts, nor will the fabric edge be separated from the upper body frame 1 due to stress caused by folding too little.
[0042] After the fabric covers the surface of the upper body frame 1, the upper body frame 1 and the water-cut bracket 2 are fixed together. In order to ensure that the two are firmly fixed and avoid the area of the fabric on the back of the upper body frame 1, this embodiment designs a plurality of connecting parts 21 on the water-cut bracket 2. Since the length of the water-cut bracket is long, the number of the connecting parts 21 is ≥10. As an example, Figure 4 As shown, the water cutting bracket is provided with 15 connecting parts 21.
[0043] In actual application, before the fabric is covered on the upper body frame 1, it will be heated to make the fabric soft and tough. Figure 3 As shown, if the fabric becomes cold and hard due to slow assembly by workers, slight wrinkles may appear when the fabric is folded to the back of the upper body frame 1 at this point. A V-shaped notch or slit is provided on the fabric at this point to avoid the occurrence of such slight wrinkles.
[0044] As mentioned above, the fabric will be folded to the back of the upper body frame 1, so the bend, that is, the edge of the upper body frame 1, should be chamfered to prevent the sharp cuts on the edge from damaging the fabric. At the same time, the top of the side of the water-cut bracket 2 will also contact the fabric, so the top edge of the side of the water-cut bracket 2 should also be chamfered to prevent the sharp cuts on the edge from damaging the fabric.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
