Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically, to a covering component and a vehicle. Background Technology

[0002] With rising living standards and a faster pace of life, people are spending more and more time in the vehicle's cockpit for meetings and relaxation, leading to higher demands from users for the tactile feel, aesthetic appeal, and comfort of the cockpit. Interior trim not only enhances the aesthetics and comfort of vehicle interiors but also improves noise reduction and safety to some extent, resulting in its increasing application in automotive interiors.

[0003] Currently, the fabric on body panels is typically covered using a reverse wrapping process, where the edges of the fabric are folded inwards and hidden to achieve both aesthetic appeal and durability. However, in this reverse wrapping process, the fabric thickness at the edges of the body panel is stretched and thinned under tension, which can easily lead to gaps and surface differences between the body panel and its surrounding components, affecting the overall vehicle quality. Utility Model Content

[0004] The problem this invention solves is: how to prevent gap surface differences between the covering part and the surrounding matching parts.

[0005] To solve the above problems, this utility model provides a covering component and a vehicle.

[0006] In a first aspect, the present invention provides a covering component, comprising a skeleton and a fabric layer. The skeleton includes a skeleton main body and a skeleton edge portion surrounding the skeleton main body. The fabric layer covers the outer surfaces of the skeleton main body and the skeleton edge portion, and extends from the outer surface of the skeleton edge portion to the inner surface of the skeleton edge portion. Along the direction from a first end to a second end of the skeleton edge portion, the outer surface of the skeleton edge portion gradually rises above the outer surface of the skeleton main body in a direction perpendicular to the skeleton main body. The first end of the skeleton edge portion is the inner edge of the skeleton edge portion connected to the skeleton main body, and the second end of the skeleton edge portion is the outer edge of the skeleton edge portion.

[0007] Optionally, the distance 'a' between the first end and the second end of the outer surface of the skeleton edge in a direction perpendicular to the skeleton body is between 1t / 3 and 2t / 3, where t is the thickness of the fabric layer in its natural state.

[0008] Optionally, the distance b between the first end and the second end of the outer surface of the skeleton edge portion in a set direction is between 1L / 5 and 1L / 4, wherein the set direction is parallel to the skeleton body portion and points from the first end to the second end of the skeleton edge portion, and L is the dimension of the skeleton in the set direction.

[0009] Optionally, the material thickness of the main body of the skeleton and the edge of the skeleton are equal.

[0010] Optionally, the material thickness at the edge of the skeleton increases from the first end to the second end of the edge of the skeleton.

[0011] Optionally, the frame further includes a flange portion disposed at the second end of the edge portion of the frame and located on the side of the edge portion of the frame away from its outer surface, and both the outer and inner surfaces of the flange portion are covered with the fabric layer.

[0012] Optionally, the fabric layer extends from the inner surface of the flange to the inner surface of the skeleton edge.

[0013] Optionally, the flange portion is disposed perpendicular to the main body of the skeleton.

[0014] Optionally, the material thickness of the flanged portion, the skeleton edge portion, and the skeleton body portion are equal, or the material thickness of the flanged portion increases along the direction from one end of the flanged portion connected to the skeleton edge portion to the end away from the skeleton edge portion.

[0015] Secondly, this utility model provides a vehicle including the covering component described above.

[0016] The beneficial effects of this utility model's covering and vehicle are as follows: By setting the outer surface of the frame edge portion of the skeleton to gradually rise higher than the outer surface of the frame body portion 11 along the direction from the first end to the second end, the outer surface of the entire frame edge portion is slightly higher than the outer surface of the frame body portion. Thus, when the fabric layer is wrapped onto the frame by, for example, adhesive bonding and is not stretched, the outer surface of the covering at the frame edge portion is slightly higher than its outer surface at the frame body portion. That is, there is a height difference between the outer surface of the edge portion of the covering and the outer surface of the middle main body portion. This difference is achieved when the fabric layer at the frame edge is reverse-wrapped. During the process, when the fabric layer covering the outer surface of the skeleton edge is stretched and folded onto the inner surface of the skeleton edge, the thickness of the fabric layer covering the skeleton edge is stretched and thinned under the action of tension. This compensates for the height difference between the outer surfaces of the covering part at the skeleton edge and the skeleton body, so that the outer surface of the covering part at the skeleton edge is flush with its outer surface at the skeleton body. This, in turn, makes the outer surface of the covering part flush with the outer surface of its surrounding matching parts, thereby avoiding gaps and surface differences between the covering part and its surrounding matching parts and improving product quality.

[0027] In related technologies, overlays not only enhance the aesthetics and comfort of vehicle interiors but also improve noise reduction and safety to some extent. Therefore, the application of overlays in vehicle interiors is becoming increasingly widespread. Currently, the fabric on overlays is typically wrapped using a reverse-wrapping process, where the edges of the fabric are folded inwards and hidden to achieve both aesthetics and durability. However, in this reverse-wrapping process, the fabric thickness at the edges of the overlay is stretched and thinned under tension, causing unevenness between the edge area of ​​the overlay and its surrounding components, resulting in surface defects and affecting the overall vehicle quality.

[0028] In view of the problems existing in the above-mentioned related technologies, this utility model provides a covering component and a vehicle.

[0029] Combination Figure 1 and Figure 2As shown, an embodiment of the present invention provides a covering, including a skeleton 1 and a fabric layer 2. The skeleton 1 includes a skeleton main body 11 and a skeleton edge portion 12 disposed around the skeleton main body 11. The fabric layer 2 covers the outer surfaces of the skeleton main body 11 and the skeleton edge portion 12, and extends from the outer surface of the skeleton edge portion 12 to the inner surface of the skeleton edge portion 12. Along the direction from the first end to the second end of the skeleton edge portion 12, the outer surface of the skeleton edge portion 12 gradually rises above the outer surface of the skeleton main body 11 in a direction perpendicular to the skeleton main body 11. The first end of the skeleton edge portion 12 is the inner edge of the skeleton edge portion 12 connected to the skeleton main body 11, and the second end of the skeleton edge portion 12 is the outer edge of the skeleton edge portion 12.

[0030] Specifically, the covering has a flat structure, mainly comprising a skeleton 1 and a fabric layer 2 wrapped around the skeleton 1 using a reverse wrapping process. The skeleton 1 can be a metal skeleton or a plastic skeleton, and the fabric layer 2 can be made of materials such as leather, fabric, or polyurethane (PU). The fabric layer 2 is typically wrapped around the skeleton 1 by methods such as adhesive bonding. The skeleton 1 mainly comprises a skeleton body 11 and a skeleton edge 12. The skeleton body 11 is the main area of ​​the skeleton 1, and the skeleton edge 12 is a ring-shaped structure surrounding the skeleton body 11, forming the edge area of ​​the skeleton 1. The skeleton body 11 and the skeleton edge 12 are an integral structure. The outer surfaces of the skeleton body 11 and the skeleton edge 12 are the outer surfaces of the skeleton 1, which are the outward-facing surfaces when the covering is applied. Therefore, they need to be completely covered by the fabric layer 2. Furthermore, the fabric layer 2 extends from the outer surface of the skeleton edge 12 to the inner surface of the skeleton edge 12, i.e., a reverse wrapping process is used to avoid exposing the edges of the skeleton 1. The skeleton edge portion 12 has a first end forming its inner annular edge and a second end forming its outer annular edge. The first end of the skeleton edge portion 12 is connected to and smoothly transitions with the skeleton body portion 11, and the second end of the skeleton edge portion 12 forms the edge of the entire skeleton 1. Figure 1 There is a small gap along the Z-axis (vertical direction). Specifically, the outer surface of the skeleton edge portion 12 is not flush with the outer surface of the skeleton body portion 11, but is slightly inclined relative to the outer surface of the skeleton body portion 11. Furthermore, the outer surface of the skeleton edge portion 12 is higher than the outer surface of the skeleton body portion 11, meaning the outer surface of the skeleton edge portion 12 bulges outward relative to the outer surface of the skeleton body portion 11. In other words, the outer surface of the skeleton edge portion 12 gradually moves towards one side of the fabric layer 2 relative to the outer surface of the skeleton body portion 11. Figure 1 The side facing positively upward along the Z-axis bulges out, therefore, in Figure 1 Along the Z-axis, the second end of the skeleton edge 12 is slightly higher than the first end. In practical applications, it can be as follows: Figure 1 As shown, the edge portion of the skeleton 1 is bent to form an inclined skeleton edge portion 12, or it can be done as follows: Figure 2 As shown, the edge portion 12 of the skeleton is formed by increasing the material thickness at the edge of the skeleton 1, but no specific limitation is made here.

[0031] In this embodiment, the outer surface of the skeleton edge portion 12 of the skeleton 1 can be set to gradually be higher than the outer surface of the skeleton body portion 11 along the direction from the first end to the second end, so that the outer surface of the entire skeleton edge portion 12 is slightly higher than the outer surface of the skeleton body portion 11. In this way, when the fabric layer 2 is wrapped on the skeleton 1 by means of, for example, adhesive and is not stretched, the outer surface of the covering at the skeleton edge portion 12 is slightly higher than its outer surface at the skeleton body portion 11. That is, there is a height difference between the outer surface of the edge portion of the covering and the outer surface of the middle main body portion. When the fabric layer 2 at the edge of the skeleton 1 is reverse-wrapped, that is, when the covering is wrapped on the skeleton 1, the outer surface of the covering is slightly higher than the outer surface of the skeleton body portion 11. When the fabric layer 2 on the outer surface of the skeleton edge portion 12 is stretched and folded onto the inner surface of the skeleton edge portion 12, the thickness of the fabric layer 2 covering the skeleton edge portion 12 is stretched and thinned under the action of tension, so as to offset the height difference between the outer surfaces of the covering part at the skeleton edge portion 12 and the skeleton body portion 11, so that the outer surface of the covering part at the skeleton edge portion 12 can be flush with its outer surface at the skeleton body portion 11, thereby making the outer surface of the covering part flush with the outer surface of its surrounding matching parts 30, thus avoiding gap surface difference between the covering part and its surrounding matching parts 30, and improving product quality.

[0032] Optionally, combined Figure 1 and Figure 2 As shown, the distance a between the first end and the second end of the outer surface of the skeleton edge portion 12 in the direction perpendicular to the skeleton body portion 11 is between 1t / 3 and 2t / 3, where t is the thickness of the fabric layer 2 in its natural state.

[0033] If the distance 'a' between the first and second ends of the outer surface of the skeleton edge portion 12 in the direction perpendicular to the skeleton body portion 11 is designed to be too small, the outer surfaces of the skeleton edge portion 12 and the skeleton body portion 11 will be almost flush. This will fail to offset the thickness reduction of the fabric layer 2 covering the skeleton edge portion 12 due to the reverse wrapping process, resulting in a collapse at the edge of the covering after it is matched with its surrounding matching parts 30. If the distance 'a' between the first and second ends of the outer surface of the skeleton edge portion 12 in the direction perpendicular to the skeleton body portion 11 is designed to be too large, there will be a large height difference between the outer surfaces of the skeleton edge portion 12 and the skeleton body portion 11 in the direction perpendicular to the skeleton body portion 11. This will cause the outer surface of the edge of the covering to still be higher than the outer surface of the middle body portion after the fabric layer 2 covering the skeleton edge portion 12 is stretched and thinned during the reverse wrapping process. Consequently, a bulge will appear at the edge of the covering after it is matched with its surrounding matching parts 30.

[0034] Therefore, in this optional embodiment, by setting the distance a between the first end and the second end of the outer surface of the skeleton edge portion 12 in the direction perpendicular to the skeleton body portion 11 to be between 1t / 3 and 2t / 3, it is ensured that the height difference formed between the outer surfaces of the skeleton edge portion 12 and the skeleton body portion 11 in the direction perpendicular to the skeleton body portion 11 can just offset the thickness reduction of the fabric layer 2 covering the skeleton edge portion 12 caused by the reverse wrapping process, thereby avoiding the gap surface difference between the covering part and its surrounding matching part 30.

[0035] Optionally, combined Figure 1 and Figure 2 As shown, the distance b between the first end and the second end of the outer surface of the skeleton edge portion 12 in a set direction is between 1L / 5 and 1L / 4, wherein the set direction is parallel to the skeleton body portion 11 and points from the first end to the second end of the skeleton edge portion 12, and L is the dimension of the skeleton 1 in the set direction.

[0036] It should be noted that setting the direction is also... Figure 1 In the Y-axis direction, the distance b between the first end and the second end of the outer surface of the skeleton edge 12 in the set direction is also the vertical distance from the first end to the second end of the outer surface of the skeleton edge 12.

[0037] If the distance b between the first and second ends of the outer surface of the skeleton edge portion 12 in the set direction is designed to be too small, the tilt angle of the outer surface of the skeleton edge portion 12 will be large, causing the fabric layer 2 at the connection position between the skeleton edge portion 12 and the skeleton body portion 11 to easily separate from the skeleton 1 due to stretching, resulting in the fabric layer 2 at that position not adhering to the skeleton 1. If the distance b between the first and second ends of the outer surface of the skeleton edge portion 12 in the set direction is designed to be too large, it means that the width of the skeleton edge portion 12 (i.e., the dimension of the skeleton edge portion 12 in the direction from its first end to its second end) is large, which means that when the material thickness of the edge portion of the skeleton 1 is increased to form the skeleton edge portion 12, more material will be used for the skeleton edge portion 12, resulting in a larger weight of the skeleton 1 and higher production costs.

[0038] Therefore, in this optional embodiment, by setting the distance b between the first end and the second end of the outer surface of the skeleton edge portion 12 in a set direction to be between 1L / 5 and 1L / 4, it is ensured that the fabric layer 2 can still be tightly attached to the connection position between the skeleton edge portion 12 and the skeleton body portion 11 after the reverse wrapping treatment, while reducing the material usage and production cost of the skeleton 1.

[0039] Optionally, combined Figure 1 As shown, the material thickness of the main body 11 and the edge portion 12 of the skeleton is equal. That is to say, in this embodiment, the edge portion of the skeleton 1 is bent to form the inclined edge portion 12 of the skeleton. In this way, it is not necessary to increase the material and weight of the skeleton 1, thereby reducing the production cost of the covering part.

[0040] Optionally, combined Figure 2 As shown, the thickness of the material at the edge of the skeleton 12 increases from the first end to the second end. In other words, this embodiment uses increased material thickness at the edge of the skeleton 1 to form the edge of the skeleton 12. Thus, for the sheet metal skeleton, it is not necessary to bend the edge of the skeleton 1, thereby reducing the number of processing steps and simplifying the production process.

[0041] Optionally, combined Figure 3 and Figure 4 As shown, the frame 1 also includes a flange 13, which is disposed at the second end of the frame edge 12 and located on the side of the frame edge 12 away from its outer surface. Both the outer and inner surfaces of the flange 13 are covered with a fabric layer 2.

[0042] In this optional embodiment, the flange 13 can extend from the second end of the skeleton edge 12 towards... Figure 3The flange 13 is formed by a reverse bending along the Z-axis. It should be noted that the outer and inner surfaces of the flange 13 refer to the outward and inward facing surfaces before the reverse bending. When the frame 1 has a flange 13, the fabric layer 2 can extend from the outer surface of the flange 13 to its inner surface during the reverse wrapping process, or it can extend from the outer surface of the flange 13 through its inner surface to the inner surface of the frame edge 12; no specific limitation is made here. Thus, by providing a flange 13 at the second end of the frame edge 12, the structural strength of the frame 1 and even the edge portion of the covering is enhanced. Furthermore, by placing the flange 13 on the side of the frame edge 12 away from its outer surface, the flange 13 is prevented from affecting the reverse wrapping process of the fabric layer 2. Simultaneously, the flange 13 can be used to guide the reverse wrapping of the fabric layer 2, allowing the fabric layer 2 to be better folded and hidden inside the frame 1.

[0043] Optionally, combined Figures 3 to 4 As shown, the fabric layer 2 extends from the inner surface of the flange portion 13 to the inner surface of the skeleton edge portion 12. In this way, not only can the coverage area of ​​the fabric layer 2 be increased and the coverage quality improved, but the structural strength of the edge portion of the covered part can also be further enhanced by the fabric layer 2 extending to the inner surface of the skeleton edge portion 12.

[0044] Optionally, combined Figures 3 to 4 As shown, the flange 13 is provided perpendicular to the main body 11 of the frame. This allows the covering part and the mating part 30 to fit together surface to surface, thereby increasing the contact area between the covering part and the mating part 30 while reducing the assembly gap and improving the stability of the assembly.

[0045] Optionally, combined Figure 3 and Figure 4 As shown, the thickness of the flange portion 13, the frame edge portion 12, and the frame body portion 11 is equal, or the thickness of the flange portion 13 increases along the direction from one end of the flange portion 13 connected to the frame edge portion 12 to the end away from the frame edge portion 12.

[0046] In this optional embodiment, when the edge portion of the skeleton 1 is bent to form the inclined skeleton edge portion 12, the material thickness of the flange portion 13 can be set to be equal to the material thickness of the skeleton body portion 11 and the skeleton edge portion 12, so as to reduce the material usage and weight of the skeleton 1 and reduce the production cost of the covering part. When the material thickness of the edge portion of the skeleton 1 is increased to form the skeleton edge portion 12, the material thickness of the flange portion 13 can be set to increase gradually from one end of the flange portion 13 connected to the skeleton edge portion 12 to the end away from the skeleton edge portion 12, so as to facilitate direct bending of the skeleton edge portion with increasing material thickness to form the flange portion 13.

[0047] This utility model provides a vehicle including the covering component described above.

[0048] The beneficial effects of the vehicle in this embodiment are the same as those of the covering component described above, and will not be repeated here.

[0049] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
