Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an interior panel and a vehicle. Background Technology

[0002] In the field of vehicle manufacturing, door interior panels are important internal components, and their structural stability and connection reliability are crucial. Door interior panels are typically assembled from multiple panel components, and welding is a common process for connecting different panel components during assembly.

[0003] In related technologies, a simple welded post is typically installed on one trim panel component, and another trim panel component is welded to the welded post to achieve the connection between the trim panel components. However, the molten material in the welded post is limited during the welding process, resulting in a small weld scar volume and insufficient bond strength. Under long-term vibration loads, this simple welded connection is prone to fatigue cracks in the weld scar, leading to a decrease in connection reliability. Especially in components such as door trim panels that need to withstand large loads, traditional welded post structures often fail to guarantee sufficient connection strength and durability.

In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0025] In related technologies, a simple welded post is typically installed on one trim panel component, and another trim panel component is welded to the welded post to achieve the connection between the trim panel components. However, the molten material in the welded post is limited during the welding process, resulting in a small weld scar volume and insufficient bond strength. Under long-term vibration loads, this simple welded connection is prone to fatigue cracks in the weld scar, leading to a decrease in connection reliability. Especially in components such as door trim panels that need to withstand large loads, a connection solely through a welded post often cannot guarantee sufficient strength and durability.

[0026] Furthermore, traditional welded pillars lack effective guiding designs during assembly, making it difficult to quickly and accurately align trim panel components, increasing installation difficulty and impacting production efficiency. Simultaneously, the lack of reliable pre-installation positioning when connecting two trim panel components necessitates the use of additional temporary fixing structures to maintain their relative positions during pre-welding processes. This not only increases the number of parts and production costs but also adds inconvenience to assembly operations.

[0027] Firstly, referring to Figure 1 , Figure 2 and Figure 6This application provides an interior trim panel, which includes a first trim panel 1, a second trim panel 2, and a connecting structure 3. The first trim panel 1 is connected to the second trim panel 2 through the connecting structure 3. The connecting structure 3 includes a connecting post 31, which is disposed on the first trim panel 1 and has a slot 34. The second trim panel 2 is sleeved on the connecting post 31 and is secured in the slot 34. The second trim panel 2 has a connecting part 21, which surrounds the connecting post 31 and is connected to the connecting post 31.

[0028] In this embodiment, the second trim panel 2 is fitted onto the connecting post 31 and secured within the slot 34, achieving precise positioning and pre-fixation of the second trim panel 2. Based on this, it is connected to the connecting post 31 via the connecting part 21, forming a more stable connection interface. This structural design not only ensures the accurate positioning of the second trim panel 2 but also enhances the connection strength, improves the overall structural stability and vibration resistance, thereby guaranteeing the reliability of the interior trim panel during long-term use.

[0029] For example, the first trim panel 1 and the second trim panel 2 refer to the upper trim panel and the lower trim panel in the interior trim panel, respectively, but the scope of protection of the embodiments of this application is not limited thereto. In other feasible examples, the first trim panel 1 and the second trim panel 2 may also represent other trim panel components in the interior trim panel assembly that need to be interconnected. This naming is only used to clearly illustrate the technical solution of the embodiments of this application and does not constitute a limitation on the specific type, location or function of the trim panel.

[0030] In this embodiment, the first trim panel 1 and the second trim panel 2 are respectively the upper trim panel of the interior trim panel and the lower trim panel of the interior trim panel. In some other embodiments, the first trim panel 1 and the second trim panel 2 may also represent other trim panel components.

[0031] In some embodiments, the connecting portion 21 is welded to the connecting post 31. The connecting portion 21 can provide sufficient molten material during the welding process, which helps to form a larger and more fully bonded weld structure, thereby significantly improving the mechanical strength of the weld joint.

[0032] For example, refer to Figure 3 The connecting part 21 includes spaced-apart protrusions 211; multiple protrusions 211 are distributed circumferentially along the connecting post 31, and each protrusion 211 is welded to the outer surface of the connecting post 31. During the welding process, the molten material between adjacent protrusions 211 fuses to form a continuous welded structure. After welding, these spaced-apart protrusions 211 form a continuous annular structure around the connecting post 31 through the molten weld metal, thereby improving the welding strength.

[0033] In some other examples, the connecting portion 21 may also be an annular protrusion structure surrounding the connecting post 31. The annular protrusion can also provide sufficient and continuous molten material during the welding process, forming a complete and uniform weld bond with the surface of the connecting post 31.

[0034] In some embodiments, refer to Figure 2 The connecting post 31 is a tubular structure, and a guide surface 311 is provided at the end of the connecting post 31 away from the first trim panel 1. The guide surface 311 is an inclined surface. The guide surface 311 can provide effective guidance during the installation of the second trim panel 2, so that the second trim panel 2 and the connecting post 31 can be quickly aligned and positioned, significantly reducing assembly resistance and ensuring a smooth installation process.

[0035] For example, the guide surface 311 is formed by beveling one half of the circumferential region at the end of the connecting post 31, while the other half of the circumferential region retains the original tubular end face structure. This asymmetrical design provides effective installation guidance while preserving the structural integrity of the end of the connecting post 31, ensuring that the second trim panel 2 can be smoothly fitted while maintaining the mechanical strength of the connecting post 31 itself.

[0036] In some embodiments, refer to Figure 2 and Figure 6 The connecting post 31 is provided with a support portion 32 and a snap-fit ​​portion 33 along the axial direction, and a groove 34 is formed between the support portion 32 and the snap-fit ​​portion 33. The second decorative plate 2 is provided with a through hole that mates with the connecting post 31, and is sleeved on the connecting post 31 through the through hole. The second decorative plate 2 is in contact and fits against the support portion 32 and the snap-fit ​​portion 33 respectively.

[0037] During assembly, the second decorative panel 2 moves axially along the connecting post 31. After its through-hole edge passes the locking part 33, it is stably locked in the slot 34. At this time, the lower surface of the second decorative panel 2 is in close contact with the upper surface of the support part 32, while its upper surface is in contact with the lower surface of the locking part 33. By forming the slot 34 between the support part 32 and the locking part 33, the second decorative panel 2 is precisely positioned in the axial direction, providing a stable and reliable pre-positioning guarantee for subsequent welding processes.

[0038] It is understood that the slot 34 in this embodiment does not have a continuous slot wall, but is instead defined by the axial gap between the circumferentially spaced support portions 32 and the engaging portions 33. This discontinuous structural design reduces material usage while maintaining the overall structural strength of the connecting post 31, ensuring accurate positioning and reliable engagement. Those skilled in the art should recognize that the key to the functionality of the slot 34 lies in forming an effective positioning mating surface, rather than the continuity of the slot wall.

[0039] In some embodiments, refer to Figure 2 and Figure 6The snap-fit ​​part 33 is an elastic snap-fit ​​part, which facilitates the second decorative panel 2 to enter the slot 34.

[0040] For example, by providing slots between the three sides of the snap-fit ​​portion 33 and the connecting post 31, it can elastically contract towards the center of the connecting post 31 when subjected to radial pressure, and automatically return to its initial position after the external force is released. It should be understood that any elastic structure capable of inward contraction under force and self-recovery under no force is applicable to this embodiment, and is not limited to the specific form shown in the figure.

[0041] For example, refer to Figures 4 to 6 The snap-fit ​​portion 33 has an axial cross-sectional profile that is thicker in the middle and thinner at both ends. A guide slope 331 is provided at the end of the snap-fit ​​portion 33 furthest from the first trim panel 1, and a welding engagement slope 332 is provided at the end of the snap-fit ​​portion 33 closest to the first trim panel 1. In this example, the snap-fit ​​portion 33 adopts a unique cross-sectional design that is thicker in the middle and thinner at both ends. The guide slope 331 at its top effectively reduces the insertion resistance during the assembly of the second trim panel 2, achieving smooth insertion. The welding engagement slope 332 at its bottom provides a larger fusion area for the welding process, significantly improving the welding strength.

[0042] For example, the guide slope 331 is a smooth slope, which further reduces the introduction resistance when assembling the second trim panel 2.

[0043] For example, a groove (not shown in the figure) is formed on the surface of the welding mating bevel 332. During the welding process, the molten material generated by the heating of the connecting part 21 not only forms weld scars on the contact surface with the welding mating bevel 332, but also flows in and completely fills the groove. After cooling and solidification, this filling material forms a strong mechanical interlocking structure in the groove, increasing the pull-out and shear resistance of the weld joint, thereby improving the weld strength.

[0044] For example, the guide ramp 331 and the welding mating ramp 332 intersect at their ends. This structural design allows the snap-fit ​​portion 33 to present a complete double-rammed feature in the axial section, which ensures that the second trim panel slides smoothly into the slot and provides ideal filling space for the welding molten material, while reducing the amount of material used through optimized geometry.

[0045] For example, the connecting portion 21 is at least partially welded to the snap-fit ​​portion 33. Through the welding process, the snap-fit ​​portion 33, which originally had elastic characteristics, is permanently rigidly connected to the connecting portion 21, thereby changing it from a movable elastic snap-fit ​​state to a permanently fixed rigid connection state.

[0046] In some embodiments, refer to Figure 2The support part 32 is a plate structure, which is perpendicular to the outer surface of the first decorative panel 1 and the connecting column 31. Multiple support parts 32 are provided, and the multiple support parts 32 are spaced apart along the circumference of the connecting column 31. This spaced layout provides uniform support for the second decorative panel 2 while reducing the amount of material used and realizing a lightweight design of the structure.

[0047] For example, four support parts 32 are arranged at intervals. The four support parts 32 are evenly distributed around the connecting column 31. The top surface of each support part 32 away from the first decorative panel 1 is kept on the same plane, and together they form a complete support reference plane.

[0048] Secondly, embodiments of this application provide a vehicle that includes the aforementioned interior panel. Therefore, the vehicle has all the beneficial effects of the aforementioned interior panel, which will not be repeated here.

[0049] The vehicle in this embodiment can be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific limitation in this regard.

[0050] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0051] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
