Description

Technical Field

[0001] The utility model relates to the field of automobile door panels, in particular to a covering component avoidance structure. Background Art

[0002] In order to improve comfort and aesthetics, the three-dimensional frames on the door panels of automobiles, such as the upper panels, the middle decorative panels, the armrest covers, etc., are often covered with a layer of decorative fabrics made of leather or other materials on the side visible to the passengers. In actual processing, when these decorative fabrics are covered on the surface of the three-dimensional frame and hidden on the back side, since the side panels connected to the visible panels (i.e., the panels where the passenger's visible surface is located) on the three-dimensional frame often have a certain height and are greater than the thickness of the visible panels, for example, the thickness is 3mm and the height is 10mm, the decorative fabrics often accumulate at the connection point between the two side panels, because the decorative fabrics covering the visible panels and the two side panels converge here, causing wrinkles in the decorative fabrics, which will affect the installation and coordination of the three-dimensional frame and other components, thereby causing a non-negligible gap between the two. Utility Model Content

[0003] The utility model aims to provide a covering piece avoidance structure to solve the problem of wrinkles of decorative fabrics on a three-dimensional frame in the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a covering part avoidance structure, including a three-dimensional frame, the three-dimensional frame including a visible plate and a first side plate and a second side plate connected thereto, the first side plate is connected to the second side plate and the height of both is greater than the thickness of the visible plate, the first side plate is provided with an avoidance groove at the connection with the second side plate, the avoidance groove is combined with the second side plate to be U-shaped, and the bottom of the groove is located near one end of the visible plate.

[0005] The principle of this scheme is that in the process of wrapping the decorative fabric on the surface of the three-dimensional skeleton, the decorative fabric will accumulate at the intersection of the visible plate of the three-dimensional skeleton and the first side plate and the second side plate connected thereto. The general practice is to cut off the excess decorative fabric here, that is, the decorative fabric has a V-shaped notch here, but the depth of the V-shaped notch is not easy to control during the actual operation on site. If it is cut too shallow, there will still be wrinkles here. If it is cut too deep, the notch can be seen on the visible plate, affecting the appearance, so that the entire product is scrapped. In addition, in Chinese patent ZL202321319895.6 (body and door panel on door interior panel), a method is adopted: cut off the excess decorative fabric located here, and then sew the decorative fabric with blind stitches, design a wire groove at the edge of the upper body skeleton (i.e., the covering structure), and then hide the blind stitches in the wire grooves to solve the problem of wrinkles. Although this method can effectively solve the problem of wrinkles, its process is relatively complicated. To accurately put the blind stitches into the small wire grooves, it requires high sewing skills of workers. The inventor of this solution did not follow the general idea to make improvements from the decorative fabric, but carefully observed the three-dimensional frame with decorative fabric, and noticed that the decorative fabrics respectively covering the visible plate, the first side plate and the second side plate first converged at the intersection of the three plates and then hid to the back of the three-dimensional frame. So is there a way to prevent them from intersecting? Therefore, the inventor improved the design, so that the first side plate is provided with an avoidance groove at the connection with the second side plate, and the avoidance groove is open on one side in combination with the second side plate, and the bottom of the groove is located at the end close to the visible plate, that is, the groove is located at the end away from the visible plate. In actual operation, the decorative fabrics covering the visible plate, the first side plate and the second side plate will be hidden from the bottom and both sides of the avoidance groove to the back of the three-dimensional frame. This solution changes the process of the decorative fabrics first merging and then hiding at the intersection of the three plates, so that they are hidden to the back of the three-dimensional frame from different positions of the avoidance groove, and the avoidance groove can accommodate the decorative fabrics. Therefore, this solution effectively improves the accumulation of the decorative fabrics and achieves the purpose of improving wrinkles.

[0006] Preferably, as an improvement, the three-dimensional skeleton is an armrest cover plate, the visible plate is a top plate of the armrest cover plate, and the first side plate is a side plate located at an end away from a passenger.

[0007] This scheme shows a specific three-dimensional skeleton.

[0008] Preferably, as an improvement, the groove bottom thickness is ≤3 mm.

[0009] In this solution, this design limits the thickness of the groove bottom to prevent the groove bottom from being too thick and forming a new three-plate intersection with the visible panel and the second side panel. The thinner groove bottom can prevent the decorative fabric from being easily wrinkled at both ends of the groove bottom.

[0010] Preferably, as an improvement, the groove bottom width is 18-25 mm.

[0011] In this solution, the width range of the groove bottom is designed to ensure that the avoidance groove has enough space to accommodate the decorative fabric.

[0012] Preferably, as an improvement, the groove bottom width is 20 mm.

[0013] Preferably, as an improvement, the groove wall of the avoidance groove close to the first side plate is inclined, so that the groove bottom width is smaller than the groove opening width of the avoidance groove.

[0014] In this solution, the first side panel and the avoidance groove are gradually inclined, which can increase the accommodating space of the avoidance groove and increase the angle at the corner of the first side panel so that the decorative fabric is less likely to wrinkle here.

[0015] Preferably, as an improvement, the surface of the groove wall is provided with a texture.

[0016] In actual applications, when the decorative fabric is hidden on the back of the armrest cover by gluing, the surface of the groove wall is provided with a texture to increase the surface roughness, thereby increasing the adhesion between the decorative fabric and the armrest cover, making the adhesion more secure.

[0017] Preferably, as an improvement, the edge of the avoidance groove is rounded.

[0018] The design of this solution can prevent sharp corners from damaging the decorative fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a schematic diagram of the back structure of Example 1 of the utility model.

[0020] The reference numerals include: armrest cover plate 1 , visible plate 2 , first side plate 3 , second side plate 4 , avoidance groove 5 , groove bottom thickness 51 , groove bottom width 52 . DETAILED DESCRIPTION

[0021] The following is further described in detail through specific implementation methods:

[0022] Embodiment 1: A covering component avoidance structure includes a three-dimensional frame, wherein the three-dimensional frame includes a visible plate 2 and a first side plate 3 and a second side plate 4 connected thereto, wherein the first side plate 3 and the second side plate 4 are connected and the height of the first side plate 3 and the second side plate 4 is greater than the thickness of the visible plate 2. Here, this embodiment is specifically described by taking the armrest cover plate 1 as the three-dimensional frame, as shown in FIG. Figure 1 As shown, the visible panel 2 is the top panel of the armrest cover 1, and the first side panel 3 is the side panel located at the end away from the passenger.

[0023] In order to improve the problem that the decorative fabric is prone to wrinkles at the intersection of the visible panel 2, the first side panel 3 and the second side panel 4, the first side panel 3 is provided with an avoidance groove 5 at the connection with the second side panel 4. The avoidance groove 5 is U-shaped in combination with the second side panel 4, and the bottom of the groove is located at one end close to the visible panel 2. Here, the avoidance groove 5 can be regarded as separating the first side panel 3 from the second side panel 4, so that the visible panel 2, the first side panel 3 and the second side panel 4 no longer have a situation of three panels intersecting. Therefore, in actual operation, the decorative fabric covering the visible panel 2, the first side panel 3 and the second side panel 4 will be hidden from the bottom and both sides of the avoidance groove 5 to the back of the armrest cover 1, so that the decorative fabric will no longer accumulate in one place and wrinkle.

[0024] Based on the above purpose, as a further improvement, the groove bottom thickness 51 of the avoidance groove 5 is designed to be ≤3mm, so as to prevent the groove bottom from being too thick and forming a new intersection of three plates with the visible plate 2 and the second side plate 4, and the thinner groove bottom can make it difficult for the decorative fabric to wrinkle at both ends of the groove bottom. Of course, even if a little wrinkle is generated at both ends of the groove bottom, since the groove bottom is located in a place invisible to passengers, and the groove bottom does not directly contact the other components when the armrest cover plate 1 is installed with other components, the little wrinkle here will not affect the installation and cooperation of the armrest cover plate 1 with other components. If the thickness of the visible plate is ≤3mm, the groove bottom thickness 51 of the avoidance groove 5 is equal to the thickness of the visible plate.

[0025] In addition, the groove bottom width 52 of the avoidance groove 5 is designed to be 18-25 mm to ensure that the avoidance groove 5 has enough space to accommodate the decorative fabric, and to avoid the decorative fabric from piling up in a narrow space and protruding from the avoidance groove 5, thereby affecting the installation and coordination of the armrest cover 1 and the other components. Preferably, the groove bottom width 52 is 20 mm.

[0026] In addition, the edges of the avoidance groove 5 are designed to be rounded to prevent sharp corners on the edges from causing damage such as puncture and scratching to the decorative fabric.

[0027] Finally, the groove wall of the avoidance groove 5 close to the first side panel 3 is designed to be inclined so that the groove bottom width 52 is smaller than the groove opening width. One purpose is to increase the accommodation space of the avoidance groove 5 to avoid the narrow space causing the decorative fabric to pile up and protrude from the avoidance groove 5, thereby affecting the installation and coordination of the armrest cover 1 and the other components; the second purpose is to increase the angle at the corner of the first side panel 3 so that the decorative fabric can be slowly wrapped and transitioned here without easily generating wrinkles. When the decorative fabric is hidden on the back of the armrest cover 1, it is generally glued to the back by gluing. Therefore, the surface of the groove wall can also be designed to have a texture. Because the design of the avoidance groove 5 greatly increases the space for accommodating the decorative fabric, and the decorative fabric can also be unfolded here, the textured surface of the groove wall can increase the surface roughness, thereby increasing the adhesion between the decorative fabric and the armrest cover 1, making the adhesion more firm. The texture can be leather grain, stripes, bumps, etc.
