Description

Technical Field

[0001] The utility model relates to the field of automobile interior decoration structures, and particularly relates to an ornament for an upper trim panel of an automobile interior. Background Art

[0002] The ornaments for the upper trim panels of automobile interiors are an important part of automobile interior decoration. They not only have aesthetic and decorative functions, but also often undertake certain functional and practical functions. Specifically, the ornaments for the upper trim panels of automobile interiors can select some high-quality materials such as metal trim panels for decoration; they can also be used to cover internal mechanical structures or wire harnesses to keep the interior of the vehicle clean and beautiful, and cooperation structures for some control components, cup holders, etc. need to be provided to facilitate various operations by drivers and passengers. The ornaments for the upper trim panels of automobile interiors are usually fixed to the vehicle body by means of snap structures, screws or double-sided adhesives.

[0003] On the one hand, in order to improve the aesthetics of the ornaments for the upper trim panels of automobile interiors, a spraying process generally needs to be carried out on the surface, and the appearance requirements are high. In order to ensure the touch feel, the products are generally designed into a shape with R corners, which are smooth and will not feel cutting. For products with R corners, the product requires that the mold parting line cannot have obvious discontinuities in the mold structure, and the processing accuracy requirements for the mold are very high. Coupled with the fact that spraying high-gloss paint will magnify the defects of the parting line, the requirements are even higher. The parting line of the existing product structure is on the A surface, which directly connects the inclined planes in two directions, that is, the top inclined plane 101 is directly connected to the bottom inclined plane 103, and a parting line 104 is formed between them. The mold matching accuracy of this scheme is very demanding and it is difficult to meet the mass production requirements, as Figure 1 shown.

[0004] On the other hand, for the fixation of the ornaments for the upper trim panels of automobile interiors, the existing ornaments for the upper trim panels of automobile interiors generally have a control component installation area and a cup holder installation area. It is easy to have unstable problems such as warping at the edges of the two areas, affecting the use experience. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an ornament for an upper trim panel of an automobile interior in order to overcome the defects of the existing technology that the parting line of the existing ornament for the upper trim panel of an automobile interior is on the A surface, which is difficult to mass-produce, and the overall structure is fixed unstably.

[0006] The purpose of the utility model can be realized by the following technical solutions:

The decorative part is a shell structure that matches the shape of the upper trim panel of the automobile interior. The decorative part body has a shape with R corners, including a top slope surface, a front steep slope surface, and a bottom slope surface that are sequentially distributed from top to bottom. The top slope surface and the front steep slope surface both slope obliquely upward, and the bottom slope surface slopes obliquely downward. The angle between the front steep slope surface and the vertical direction is within the range of 1-10 degrees. The top slope surface and the front steep slope surface are smoothly transitionally connected, and a parting line is formed between the front steep slope surface and the bottom slope surface.

[0008] The decorative part body is provided with a control component installation area and a cup holder installation area. E-shaped positioning parts and welding parts are provided around the control component installation area and the cup holder installation area. The two opposite sides of the cup holder installation area protrude towards the center, and a buckle structure is provided at the protruding end of the cup holder installation area.

[0009] Further, the top slope surface, the front steep slope surface, and the bottom slope surface are all curved slopes.

[0010] Further, the decorative part body is also provided with a concave accommodation cavity. A positioning and fixing component is provided at the bottom of the accommodation cavity. The positioning and fixing component includes a support platform, a cross-shaped guide post, and an I-shaped welding plate. The bottom of the support platform is connected to the accommodation cavity through a connecting plate. The top of the support platform is a plane. The cross-shaped guide post and the I-shaped welding plate are arranged side by side on the top of the support platform. The upper trim panel of the automobile interior is provided with a cross-shaped guide groove that matches the cross-shaped guide post and a connecting groove that matches the I-shaped welding plate.

[0011] Further, the cross-shaped guide post includes a guide main body with an H-shaped cross-section. Two guide blocks are provided at the four corners of the guide main body. The two guide blocks are respectively located on the two sides of each corner of the guide main body that are far from the guide main body, and slopes are provided at the tops of the respective guide blocks.

[0012] Further, the I-shaped welding plate includes a left support plate, a right support plate, and a middle connecting plate. The left support plate and the right support plate are both convex-shaped plate structures. The three ends of the middle connecting plate are respectively connected to the left support plate, the right support plate, and the support platform.

[0013] Further, the E-shaped positioning parts and the welding parts are both distributed alternately along the edges of the control component installation area and the cup holder installation area. An upper trim panel connection area of the automobile interior is formed between the distribution lines of the E-shaped positioning parts and the distribution lines of the welding parts.

[0014] Further, the E-shaped positioning part is a protrusion with an E-shaped cross-section, forming two grooves distributed side by side. The groove end of the E-shaped positioning part faces the upper trim panel connection area of the automobile interior.

[0015] Furthermore, the welded part comprises a welded main body plate, the bottom of the welded main body plate is connected to the decorative part main body, and both sides of the welded main body plate are also connected to the decorative part main body via reinforcing ribs.

[0016] Furthermore, the main body of the decorative element is made of metal.

[0017] Furthermore, the main body area of ​​the decorative component main body is also provided with a plurality of main body welding structures and main body guiding structures.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] (1) The utility model optimizes the setting of the R-angle parting line of the automobile interior decoration upper panel decorative parts. Most of the existing automobile interior decoration upper panel decorative parts only have a top slope surface and a bottom slope surface connected to each other, and the formed parting line is relatively high and located on the A surface of the product. The corresponding manufacturing model has higher precision requirements and is difficult to meet mass production requirements; the utility model further sets a front steep slope surface in the front part of the top slope surface, which is connected to the bottom slope surface in the form of a steep slope. On the one hand, it still has a smooth surface shape, and on the other hand, it realizes the downward movement of the parting line and leaves the A surface area, which greatly reduces the difficulty of the mold and improves the stability of mass production;

[0020] In addition, the utility model provides E-shaped positioning parts and welding parts for fixing the control component installation area and the cup holder installation area of ​​the decorative part body. The E-shaped positioning parts realize precise positioning by means of double guide grooves, and realize reliable fixation in cooperation with the welding parts. In view of the problem that the raised part in the middle of the cup holder installation area is easy to warp up, a buckle structure is specially provided, which can realize the snap connection with the upper trim panel of the automobile interior, thereby improving the stability of the overall structural connection.

[0021] (2) The present invention takes into account that if the E-shaped positioning member and the welding member are arranged opposite to each other, it is easy to cause an interference fit with the connecting strip, and there is no expansion margin during use, which is inconvenient to install. Therefore, it is proposed to stagger the E-shaped positioning member and the welding member, so that the appropriate position adjustment can be made when connecting the automobile interior upper trim panel, and ultimately the two ends of the connecting strip of the automobile interior upper trim panel can be positioned and fixed by the E-shaped positioning member and the welding member respectively, so as to ensure the stability of the overall installation effect.

[0022] (3) In view of the fixing problem of the concave accommodation cavity in the present utility model, since the surface has a large undulating slope, it is difficult to set corresponding-sized welding parts and positioning parts for fixing, and the size and layout requirements are complex. Therefore, this solution provides a positioning and fixing component with higher positioning and fixing performance. It is guided by a cross-shaped guide post, and the cross-shaped guide post forms a total of 8 guide grooves, namely up and down, left and right, upper left, lower left, upper right, and lower right, realizing all-round guiding and fixing on the plane; welding and fixing are achieved through an I-shaped welding plate, and support plates are provided at both ends of the I-shaped welding plate to achieve support and fixing, which is more stable and reliable.

[0037] Embodiment 1

[0038] As Figure 2As shown in the figure, this embodiment provides a decorative part for the upper trim panel of an automobile interior, including a decorative part main body 1. The decorative part is a shell structure that matches the shape of the upper trim panel of the automobile interior, such as Figure 3 As shown, the decorative part main body 1 has a shape with R corners, including a top slope surface 101, a front steep slope surface 102, and a bottom slope surface 103 that are distributed in sequence from top to bottom. Both the top slope surface 101 and the front steep slope surface 102 are inclined obliquely upward, and the bottom slope surface 103 is inclined obliquely downward. The angle between the front steep slope surface 102 and the vertical direction is within the range of 1-10 degrees. The top slope surface 101 and the front steep slope surface 102 are smoothly connected in a transitional manner, and a parting line 104 is formed between the front steep slope surface 102 and the bottom slope surface 103;

[0039] As Figure 4 shown, the decorative part main body 1 is provided with a control component installation area 105 and a cup holder installation area 106. E-shaped positioning parts 2 and welding parts 3 are provided around both the control component installation area 105 and the cup holder installation area 106. The opposite sides of the cup holder installation area 106 bulge towards the center. A buckle structure 4 is provided at the protruding end of the cup holder installation area 106. A buckle matching structure is correspondingly provided on the upper trim panel of the automobile interior to achieve the clamping connection between the two. In this solution, the buckle structure 4 is a column with a clamping hole in the middle.

[0040] This solution optimizes the R corner parting line 104 of the decorative part for the upper trim panel of the automobile interior. Most of the existing decorative parts for the upper trim panel of the automobile interior only set the top slope surface 101 and the bottom slope surface 103 to be connected to each other, and the formed parting line 104 is relatively high and located on the A surface of the product. The corresponding manufacturing model accuracy requirements are higher and it is difficult to meet the mass production requirements; the present utility model also sets a front steep slope surface 102 at the front of the top slope surface 101, which is connected to the bottom slope surface 103 in the form of a steep slope. On the one hand, it still has a smooth surface shape, and on the other hand, it realizes the downward movement of the parting line 104, getting out of the A surface area, greatly reducing the difficulty of the mold and improving the stability of mass production;

[0041] In addition, this solution sets E-shaped positioning parts 2 and welding parts 3 for both the control component installation area 105 and the cup holder installation area 106 of the decorative part main body 1 for fixation. The E-shaped positioning parts 2 achieve precise positioning through the double guide groove method and cooperate with the welding parts 3 to achieve reliable fixation; and aiming at the problem that the middle part of the cup holder installation area 106 is prone to warping, a buckle structure 4 is specially set, which can achieve the clamping connection with the upper trim panel of the automobile interior and improve the stability of the overall structure connection.

[0042] The top slope surface 101, the front steep slope surface 102, and the bottom slope surface 103 are all curved slopes, forming an R-angle shape. The above-mentioned curved slopes mainly form arc-shaped curves at the ends of the slope surfaces. Optionally, the angle between the top slope surface 101 and the vertical direction is within the range of 40-60 degrees, and the angle between the bottom slope surface 103 and the vertical direction is within the range of 30-40 degrees.

[0043] Specifically, as Figure 5 shown, the E-shaped positioning members 2 and the welding members 3 are alternately distributed along the edges of the control component installation area 105 and the cup holder installation area 106. A connection area for the upper interior trim panel of the vehicle is formed between the distribution lines of the E-shaped positioning members 2 and the distribution lines of the welding members 3. The upper interior trim panel of the vehicle can be correspondingly provided with connection bars to achieve cooperation and connection with the E-shaped positioning members 2 and the welding members 3.

[0044] If the E-shaped positioning members 2 and the welding members 3 are arranged facing each other, it is easy to cause an interference fit with the connection bars, leaving no expansion and contraction margin during use and making installation inconvenient. The present solution proposes the staggered arrangement of the E-shaped positioning members 2 and the welding members 3, which can make appropriate position adjustments when connecting the upper interior trim panel of the vehicle, and finally ensure that both ends of the connection bar of the upper interior trim panel of the vehicle are positioned and fixed by the E-shaped positioning members 2 and the welding members 3 respectively, ensuring the stability effect of the overall installation.

[0045] The E-shaped positioning member 2 is a protrusion with an E-shaped cross-section, forming two grooves distributed side by side. The groove ends of the E-shaped positioning member 2 face the connection area for the upper interior trim panel of the vehicle.

[0046] The welding member 3 includes a welding main body plate, the bottom of which is connected to the decorative member main body 1, and both sides of the welding main body plate are also connected to the decorative member main body 1 through reinforcing ribs.

[0047] The two grooves distributed side by side provided by the E-shaped positioning member 2 can provide more accurate positioning and fixing, and cooperate with the plate-shaped welding member 3 on the outside to achieve position fixing in all directions on the plane, making the overall connection effect more stable.

[0048] In this embodiment, the decorative member main body 1 is made of a metal material.

[0049] The main body area of the decorative member main body 1 is also provided with a plurality of main body welding structures and main body guiding structures to achieve positioning and fixing of the remaining areas.

[0050] Optionally, the decorative part body 1 is also provided with a concave accommodating cavity 107, and the bottom of the accommodating cavity 107 is provided with a positioning and fixing component, which includes a support platform 5, a well-shaped guide column 6 and an I-shaped welding plate 7. The bottom of the support platform 5 is connected to the accommodating cavity 107 through a connecting plate, and the top of the support platform 5 is a plane. The well-shaped guide column 6 and the I-shaped welding plate 7 are installed side by side on the top of the support platform 5, and the upper decorative panel of the automobile interior is provided with a well-shaped guide groove matching with the well-shaped guide column 6 and a connecting groove matching with the I-shaped welding plate 7.

[0051] The well-shaped guide column 6 includes a guide body 601 with an H-shaped cross-section. Two guide blocks 602 are provided at the four corners of the guide body 601. The two guide blocks 602 are respectively located on two sides of each corner of the guide body 601 away from the guide body 601, and each guide block 602 has a slope on the top.

[0052] The I-shaped welding plate 7 includes a left support plate 701, a right support plate 702 and a middle connecting plate 703. The left support plate 701 and the right support plate 702 are both convex plate structures. The three ends of the middle connecting plate 703 are respectively connected to the left support plate 701, the right support plate 702 and the support platform 5.

[0053] For the concave accommodating cavity 107, due to the large undulating slope of its surface shape, it is difficult to set corresponding large and small welding parts 3 and positioning parts for fixation, and the size and layout requirements are complex. In this regard, the present solution provides a positioning and fixing component with higher positioning and fixing performance, which is guided by a well-shaped guide column 6. The well-shaped guide column 6 forms a total of 8 guide grooves, including up and down, left and right, upper left, lower left, upper right, and lower right, to achieve all-round guidance and fixation on the plane; welding and fixation are achieved by an I-shaped welding plate 7, and support plates are set at both ends of the I-shaped welding plate 7 to achieve support and fixation, which is more stable and reliable.

[0054] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
