[0002] Among the plastic exterior trim parts in vehicles, taking the lower door trim panel as an example, the lower trim panel is mainly used to prevent sand and gravel from splashing and damaging the vehicle body, as well as to prevent mud and water from entering the vehicle interior, and also serves a certain decorative function. Currently, the lower trim panel is usually injection molded in one piece. A flange is provided on the front door lower trim panel near the rear door lower trim panel. This flange is used to seal the inner cavity of the front door lower trim panel. However, due to manufacturing issues, the front and rear door lower trim panels are prone to interference during assembly, affecting assembly efficiency. Furthermore, during the opening or closing of the doors, the front and rear door lower trim panels are prone to causing abnormal noises due to mutual interference, affecting the user experience. Utility Model Content

[0003] The main purpose of this utility model is to propose a vehicle exterior trim and a vehicle, which aims to solve the technical problems of low assembly efficiency of the lower trim panel of the car door and the easy occurrence of abnormal noise during the opening and closing of the car door.

[0004] To achieve the above objectives, this utility model proposes a vehicle exterior trim piece, including a front door lower trim panel and a rear door lower trim panel that are adjacent and spaced apart, and the direction from the front door lower trim panel to the rear door lower trim panel is defined as the first direction;

[0005] The lower trim panel of the front door includes a first outer panel, a first flange, and a plurality of reinforcing ribs. The first flange is installed on one side of the first outer panel. A glue-reducing groove is provided at the root of the first flange where it connects to the first outer panel. The first flange is inclined in a direction opposite to the first direction. The plurality of reinforcing ribs are installed at intervals on the inner wall of the glue-reducing groove along the extension direction of the glue-reducing groove.

[0006] In one embodiment, the angle between the first flange and the first outer panel is defined as α on the side of the first flange that is close to the lower trim panel of the rear door.

[0007] Then, α satisfies: α∈[92°, 98°].

[0008] In one embodiment, the side of the adhesive reduction groove away from the first outer plate has a rounded corner, and the reinforcing rib is attached to the inner wall of the adhesive reduction groove.

[0009] In one embodiment, the lower trim panel of the front door further includes a reinforcing rib, which is installed on the side of the first flange facing away from the reinforcing rib and at the connection between the first flange and the first outer panel.

[0010] In one embodiment, there are multiple reinforcing ribs, which are spaced apart.

[0011] In one embodiment, the lower trim panel of the rear door includes a second outer panel and a second flange. The second flange is installed on one side of the second outer panel and is disposed on the same side as the first flange, with a preset gap between the first flange and the second flange.

[0012] In one embodiment, the lower trim panel of the rear door further includes a baffle strip, which is installed on the side of the second flange facing the first flange, and the baffle strip extends along the height direction of the second flange;

[0013] A retaining edge is formed between the end of the first outer plate near the second outer plate and the first flange, and the retaining edge partially overlaps with the retaining strip in the direction from the side of the first outer plate where the first flange is installed to the other side.

[0014] In one embodiment, the lower trim panel of the rear door further includes a plurality of reinforcing ribs, which are spaced apart and installed at the connection between the second outer panel and the second flange.

[0015] In one embodiment, the lower trim panel of the front door further includes a first decorative strip, and the lower trim panel of the rear door further includes a second decorative strip. Both the first decorative strip and the second decorative strip extend along the first direction, and the first decorative strip is installed on the side of the first outer panel away from the first flange, and the second decorative strip is installed on the side of the second outer panel away from the second flange.

[0016] This utility model also proposes a vehicle including the vehicle exterior trim as described in any one of the above embodiments, the vehicle further including a front door and a rear door, the lower trim panel of the front door being installed at the bottom of the front door, and the lower trim panel of the rear door being installed at the bottom of the rear door.

[0017] According to the technical solution of this utility model, the vehicle exterior trim includes a front door lower trim panel and a rear door lower trim panel that are adjacent and spaced apart. The direction from the front door lower trim panel to the rear door lower trim panel is defined as the first direction. The front door lower trim panel includes a first outer panel, a first flange, and multiple reinforcing ribs. The first flange is installed on one side of the first outer panel, and a rubber-reducing groove is formed at the root where the first flange connects to the first outer panel. The first flange is inclined in a direction opposite to the first direction. The multiple reinforcing ribs are spaced apart on the inner wall of the rubber-reducing groove along its extension direction. Thus, the inclined arrangement of the first flange pre-compensates for the angular displacement of the first flange as it rotates towards the first direction after being heated, thereby preventing the distance between the first flange and the rear door lower trim panel from being less than a preset distance due to heating. By setting multiple reinforcing ribs in the rubber reduction groove, the reinforcing ribs can provide support for the root of the first flange, which helps to improve the rigidity of the root of the first flange. This further reduces the angular displacement of the first flange as it flips toward the rear vehicle lower trim panel, and further ensures that the distance between the first flange and the rear vehicle lower trim panel will not be excessively reduced. This prevents interference between the first flange and the rear vehicle lower trim panel during assembly and use, thereby improving the assembly efficiency of vehicle exterior parts and avoiding abnormal noises during use.

[0035] In the automotive manufacturing industry, the design and production of vehicle exterior components have always been crucial for improving overall vehicle quality and user experience. Taking the lower door trim panel (or side skirt) as an example, as a key component of the vehicle's side profile, it not only fulfills the basic functions of preventing scratches and damage from flying gravel during driving and keeping the interior clean by preventing mud and water from entering, but also enhances the overall appearance of the vehicle through unique styling and color combinations. Currently, the mainstream production process uses one-piece injection molding to manufacture the lower trim panel. This process can complete the manufacturing of complex structural components in a single molding process, effectively improving production efficiency and structural strength. At the junction of the front and rear door lower trim panels, a flange structure is typically designed. This flange structure connects to the outer panel of the lower trim panel to form an inner cavity for connection with the door sheet metal. This prevents dust intrusion and allows the flange structure to support the outer panel, ensuring the lower trim panel maintains its stable shape over long-term use.

[0036] According to the applicant's research, in actual production applications, to avoid surface shrinkage defects caused by plastic shrinkage during injection molding, designers need to set a shrinkage groove at the root of the flange. However, this structural adjustment directly leads to a reduction in the wall thickness of the flange root area, resulting in a significant decrease in local stiffness. Furthermore, after injection molding, the lower trim panel undergoes a high-temperature coating and baking process. Commonly used materials such as polypropylene undergo thermal softening under continuous high temperatures. At this point, the insufficiently stiff flange structure gradually undergoes irreversible plastic deformation under gravity, manifesting as a continuous tilt towards the rear door lower trim panel. The tilted flange mechanically interferes with the edge of the adjacent rear door lower trim panel, requiring assembly workers to adjust the installation angle, severely reducing assembly line efficiency. Moreover, after assembly, the problem of insufficient clearance due to deformation persists. When the door is opened or closed, the mutually pressing surfaces of the lower trim panels cause unpleasant rattling noises, negatively impacting the user's evaluation of the overall vehicle quality.

[0037] In view of this, the present invention proposes a vehicle exterior trim component to solve or at least alleviate the above-mentioned problems.

[0038] Please see Figures 1 to 4 In one embodiment of this utility model, the vehicle exterior trim 100 includes a front door lower trim panel 1 and a rear door lower trim panel 2 that are adjacent and spaced apart. The direction from the front door lower trim panel 1 to the rear door lower trim panel 2 is denoted as the first direction X (see [reference]). Figure 1 (The direction indicated by the middle arrow X); The front door lower trim panel 1 includes a first outer panel 11, a first flange 12 and a plurality of reinforcing ribs 13. The first flange 12 is installed on one side of the first outer panel 11. A glue-reducing groove 14 is provided at the root where the first flange 12 connects to the first outer panel 11. The first flange 12 is inclined in the direction opposite to the first direction X. The plurality of reinforcing ribs 13 are installed at intervals on the inner wall of the glue-reducing groove 14 along the extension direction of the glue-reducing groove 14.

[0039] Specifically, to facilitate demolding, a shrinkage groove 14 is provided at the root of the first flange 12 on the side facing the lower rear door trim panel 2. The shrinkage groove 14 extends vertically, extending from the root of the first flange 12 to the connection between the first flange 12 and the first outer panel 11. By providing the shrinkage groove 14, it is possible to prevent surface shrinkage marks caused by excessive material thickness at the root of the first flange 12, and also to avoid insufficient shrinkage compensation at the center of the root of the first flange 12 due to uneven cooling between the surface and the interior, thereby preventing the formation of vacuum holes at the center of the root of the first flange 12. The first flange 12 is installed on the inner side of the first outer panel 11, that is, the side of the first outer panel 11 closest to the vehicle cabin. By providing the first flange 12, it is possible to prevent mud, water, debris, etc., from intruding into the door sheet metal from the side of the first outer panel 11.

[0040] According to the solution provided in this embodiment, the inclined setting of the first flange 12 is used to pre-compensate for the angular displacement of the first flange 12 after it is heated and flips towards the first direction X (that is, to pre-compensate for the displacement of the end of the first flange 12 away from the first outer panel 11 along the first direction X), thereby avoiding the distance between the first flange 12 and the rear vehicle lower trim panel being less than a preset distance due to the heating of the first flange 12. By setting multiple reinforcing ribs 13 in the glue reduction groove 14, the reinforcing ribs 13 can provide support for the root of the first flange 12, which helps to improve the rigidity of the root of the first flange 12, thereby further reducing the angular displacement of the first flange 12 flipping towards the rear vehicle lower trim panel, and further ensuring that the distance between the first flange 12 and the rear vehicle lower trim panel will not be excessively reduced, so that the first flange 12 and the rear vehicle lower trim panel will not interfere during assembly and use, thereby improving the assembly efficiency of the vehicle exterior trim 100 and avoiding abnormal noise during use.

[0041] Furthermore, directly placing the reinforcing rib 13 within the shrinkage groove 14 not only ensures the proper placement of the shrinkage groove 14 and avoids the problem of shrinkage marks at the root of the first flange 12, but also helps reduce the design difficulty of the injection mold and avoids a significant increase in mold design costs. It should be noted that the surface of the reinforcing rib 13 near the lower rear door trim panel 2 and the surface of the first flange 12 near the lower rear door trim panel 2 are located on the same plane, forming a continuous and flat support surface. This avoids shadows or discontinuities that may result from height differences or breaks, thus preventing any impact on the overall appearance of the lower front door trim panel 1.

[0042] In one embodiment of this utility model, please refer to Figure 2Defined as follows: On the side of the first flange 12 near the lower trim panel 2 of the rear door, the angle between the first flange 12 and the first outer panel 11 is α; then, α satisfies: α∈[92°, 98°]. In this embodiment, the preferred angle of α is 92°. The specific value of α needs to be determined through experiments based on the size of the first flange 12 and the thickness of the root of the first flange 12.

[0043] In one embodiment of this utility model, the side of the reducing groove 14 away from the first outer plate 11 has a rounded corner, and the reinforcing rib 13 fits against the inner wall of the reducing groove 14. Specifically, the shape of the reinforcing rib 13 matches the shape of the groove wall of the reducing groove 14, so that the reinforcing rib 13 can connect to both the first outer plate 11 and the first flange 12 at the same time, so as to provide support for the first flange 12 and avoid the formation of sharp corners in the reducing groove 14 and the reinforcing rib 13, which would lead to stress concentration. In this embodiment, four reinforcing ribs 13 are arranged at intervals of 300mm, each with a height of 3mm, a root width of 0.7mm, and a rounded corner radius of 0.5mm. To facilitate injection molding and demolding, the draft angle is set to 1°. During injection molding, the reinforcing rib 13 is injected at high speed and low pressure (injection speed 80mm / s, pressure 60MPa) to ensure that the reinforcing rib 13 is completely filled. At the same time, a water cooling circuit is added at the corresponding position in the mold to control the cooling rate of the reinforcing rib 13.

[0044] Please see Figure 5 In one embodiment of this utility model, the lower trim panel 1 of the front door further includes a reinforcing rib 15. The reinforcing rib 15 is installed on the side of the first flange 12 away from the reinforcing rib 13, and is also installed at the connection between the first flange 12 and the first outer panel 11. In this embodiment, there are multiple reinforcing ribs 15, which are spaced apart. This arrangement further enhances the rigidity of the first flange 12, thereby further reducing the angular displacement of the first flange 12. Furthermore, the first flange 12 itself is a relatively weak cantilever structure. When subjected to pressure or impact perpendicular to the plane of the first flange 12, it is prone to buckling (instability deformation) or bending inward / outward. The reinforcing rib 15 is installed close to the flange on its inner side (away from the rib side), which is equivalent to adding a lateral support point near the "cantilever root" of the first flange 12. This arrangement restricts the degree of freedom of the first flange 12, improves its resistance to buckling and lateral deformation, and keeps the first flange 12 stable under stress.

[0045] Further, please refer to Figure 2 and Figure 6In one embodiment of this utility model, the rear door lower trim panel 2 includes a second outer panel 21 and a second flange 22. The second flange 22 is installed on one side of the second outer panel 21 and is disposed on the same side as the first flange 12, forming a preset gap 3 between the first flange 12 and the second flange 22. It should be noted that, in order to reduce modifications to the injection mold and lower mold design costs, in this embodiment, a reinforcing rib 13 is only provided between the first flange 12 and the first outer panel 11, and the first flange 12 is inclined. This achieves the effect of controlling the width of the preset gap 3 to be no less than the design width, without the need to provide a reinforcing rib 13 in the second flange 22. Of course, it is understood that in some models, the shape and design spacing requirements of the front door lower trim panel 1 and the rear door lower trim panel 2 are different. A reinforcing rib 13 can also be provided between the second flange 22 and the second outer panel 21 to reduce the angular displacement of the second flange 22 flipping towards the first flange 12. The specific structure can be selected according to actual needs. In this embodiment, in order to avoid shrinkage marks between the second flange 22 and the second outer plate 21, a glue-reducing groove 14 is also provided at the root of the second flange 22.

[0046] Please see Figure 2 , Figure 3 and Figure 6 In one embodiment of this utility model, the rear door lower trim panel 2 further includes a baffle strip 23. The baffle strip 23 is installed on the side of the second flange 22 facing the first flange 12, and extends along the height direction of the second flange 22. A baffle 111 is formed between the end of the first outer panel 11 near the second outer panel 21 and the first flange 12. The baffle 111 and the baffle strip 23 partially overlap in the direction from the side of the first outer panel 11 where the first flange 12 is installed to the other side. This arrangement ensures that the preset gap 3 can be effectively blocked, thereby preventing external mud and water from splashing onto the surface of the door sheet metal parts through the preset gap 3. At the same time, the staggered arrangement of the baffle strip 23 and the baffle 111 can also prevent the front door lower trim panel 1 and the rear door lower trim panel 2 from interfering with each other during use.

[0047] In one embodiment of this utility model, please refer to Figure 6The lower rear door trim panel 2 also includes multiple reinforcing ribs 24, which are spaced apart at the connection between the second outer panel 21 and the second flange 22. The number and spacing of the reinforcing ribs 24 can be determined experimentally. By providing the reinforcing ribs 24, the bending moment resistance of the second flange 22 can be improved, which helps to increase the stiffness at the connection between the second outer panel 21 and the second flange 22. It also constrains the degree of freedom of the second flange 22, improving its resistance to buckling and lateral deformation, thus ensuring the stability of the second flange 22 under stress. Furthermore, the reinforcing ribs 24 directly support the connection area between the second flange 22 and the second outer panel 21, reducing the local stress and deformation amplitude in this connection area, which helps to extend the service life of the lower rear door trim panel 2.

[0048] In one embodiment of this utility model, please refer to Figure 1 The front door lower trim panel 1 also includes a first decorative strip 16, and the rear door lower trim panel 2 also includes a second decorative strip 25. Both the first decorative strip 16 and the second decorative strip 25 extend along a first direction X. The first decorative strip 16 is installed on the side of the first outer panel 11 facing away from the first flange 12, and the second decorative strip 25 is installed on the side of the second outer panel 21 facing away from the second flange 22. The shape and color of the first decorative strip 16 and the second decorative strip 25 can be selected according to design requirements or modified according to user needs. The first decorative strip 16 is connected to the first outer panel 11, and the second decorative strip 25 is connected to the second outer panel 21 via snap-fit ​​connections to improve the ease of installation and removal of the decorative strips.

[0049] This utility model also proposes a vehicle, which includes an exterior trim piece 100. The specific structure of the exterior trim piece 100 is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The vehicle also includes a front door and a rear door. The lower trim panel 1 of the front door is installed at the bottom of the front door, and the lower trim panel 2 of the rear door is installed at the bottom of the rear door. It should be noted that in other plastic parts of the vehicle with flanges, such as wheel arch guards, bumper deflectors, dashboard air vents, and door armrest areas, the method of setting reinforcing ribs 13 in the rubber reduction groove 14 can be adopted to improve the rigidity of the flange root.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
