[0032] Next, refer to Figures 1 - 6 to describe the vehicle interior trim panel 100 according to an embodiment of the present utility model.

[0033] The vehicle interior trim panel 100 according to an embodiment of the present utility model includes a trim panel body 1. The trim panel body 1 is an integral part made of a foaming material. Combining Figure 1 and Figure 2 as shown, a bead boundary 111 is constructed between two adjacent beads 11 on the outer surface of the trim panel body 1.

[0034] Taking the polypropylene material as an example for the foaming material, polypropylene (Expanded Polypropylene, EPP) is a high-performance foam plastic material. It is made by foaming polypropylene resin to form a highly crystalline polymer / gas composite material. Specifically, EPP is formed by heating and melting the polypropylene (PP) resin raw material, mixing in a physical foaming agent (such as gases like nitrogen, carbon dioxide, etc.), and then forming a molten mixture containing a large number of tiny bubbles through special equipment such as an extruder. This mixture is then cooled and cut into small particles, namely the so-called "foaming beads 11". These beads 11 have many tiny pores on their surfaces, which are the basis for the future foaming structure.

[0035] When these expanded beads 11 are used for molding, they are usually placed in a mold under high temperature and pressure. By reheating, the beads 11 soften and fuse with each other, while the internal gas expands to form a dense honeycomb structure. However, during the fusion process, although the beads 11 come into close contact and bond together, since each bead 11 is an independent foaming unit, the contact surface between them does not completely disappear. Especially when the molding pressure or temperature is insufficient, or the molding cycle is too short, the boundary between the beads 11 is more obvious.

[0036] Therefore, the bead boundary 111 on the surface of the EPP foam part is actually the residual trace of the original expanded bead 11 structure during the molding process, which reflects the microscopic structural characteristics inside the material.

[0037] However, the EPP foam process parts have obvious EPP bead boundaries 111 on the surface, resulting in a poor visual effect and thus a poor texture on the surface of the EPP foam process parts.

[0038] In this application, as shown in Figures 1 - 4 , a plurality of convex textures 13 and / or a plurality of concave textures 12 are further provided on the outer surface of the trim panel body 1. The convex textures 13 and the concave textures 12 are both arranged crosswise with the bead boundary 111. That is to say, either the convex texture 13 or the concave texture 12 can break the bead boundary 111, so that the outer surface of the trim panel body 1 is not a neatly arranged bead boundary 111. Moreover, after the outer surface of the trim panel body 1 is treated by the convex texture 13 or the concave texture 12, when light is projected onto the outer surface of the trim panel body 1, the glossiness of the outer surface of the trim panel body 1 can be effectively reduced, thereby weakening the visual effect and improving the texture of the outer surface of the trim panel body 1.

[0039] Here, it needs to be explained that for the outer surface of the trim panel body 1, when the trim panel body 1 is installed on the vehicle sheet metal, the side of the trim panel body 1 facing the sheet metal is the inner side, and the side facing the interior space of the carriage is the outer surface. This will not be elaborated in the following examples of this application.

[0040] In addition, the crosswise arrangement in the above example means that during the extension process of the convex texture 13 or the concave texture 12, the extension direction is different from that of the bead boundary 111, and the convex texture 13 or the concave texture 12 intersects with the bead boundary 111, so that the bead boundary 111 on the outer surface of the trim panel body 1 is no longer neatly arranged, thereby improving the visual texture of the outer surface of the trim panel body 1.

[0041] Thus, for the vehicle interior trim panel 100 according to the embodiments of the present utility model, by further providing a plurality of convex textures 13 and / or a plurality of concave textures 12 on the outer surface of the trim panel body 1, and both the convex textures 13 and the concave textures 12 are arranged to cross the bead boundary 111, the glossiness of the outer surface of the trim panel body 1 can be effectively reduced, thereby weakening the visual effect and enhancing the texture of the outer surface of the trim panel body 1.

[0042] Exemplarily, the outer surface of the trim panel body 1 has convex textures 13. The convex textures 13 are strip-shaped. In the extending direction of the convex textures 13, it can pass through one bead boundary 111, or the convex textures 13 extend relatively long and can pass through a plurality of bead boundaries 111.

[0043] Exemplarily, referring to Figures 3 - 4 As shown, the outer surface of the trim panel body 1 has concave textures 12. The concave textures 12 are strip-shaped. In the extending direction of the concave textures 12, it can pass through one bead boundary 111, or the concave textures 12 extend relatively long and can pass through a plurality of bead boundaries 111.

[0044] Exemplarily, in the projection plane where the outer surface of the trim panel body 1 is located, the area of the concave textures 12 is larger than the area of the beads 11. That is to say, the area of the concave textures 12 is larger than the area of one bead 11 on the outer surface of the trim panel body 1. It can be understood that the area of the concave textures 12 is larger than the area of two or more beads 11 on the outer surface of the trim panel body 1, so that the concave textures 12 cover the outer surface of one or more beads 11.

[0045] Exemplarily, in the projection plane where the outer surface of the trim panel body 1 is located, the area of the convex textures 13 is larger than the area of the beads 11. That is to say, the area of the convex textures 13 is larger than the area of one bead 11 on the outer surface of the trim panel body 1. It can be understood that the area of the convex textures 13 is larger than the area of two or more beads 11 on the outer surface of the trim panel body 1, so that the convex textures 13 cover the outer surface of one or more beads 11.

[0046] In some embodiments of the present utility model, the convex textures 13 and / or the concave textures 12 are embossed on the outer surface of the trim panel body 1.

[0047] Exemplarily, a concave texture opposite to the convex texture 13 or a convex texture opposite to the concave texture 12 can be constructed on the surface of the mold by chemical etching. In this way, when the foamed beads 11 are used for molding, the convex texture 13 or the concave texture 12 can be directly embossed during foaming, and the operation is simple and convenient.

[0048] In some embodiments of the present utility model, the protrusion height H1 of the convex texture 13 satisfies: 100 μm ≤ H1 ≤ 150 μm; the depression depth H2 of the concave texture 12 satisfies: 100 μm ≤ H2 ≤ 150 μm. Thus, when the convex texture 13 or the concave texture 12 meets the above conditions, the bead boundaries 111 on the outer surface of the trim body 1 can be better reduced, and the visual texture of the trim body 1 can be enhanced. In addition, by making the convex texture 13 or the concave texture 12 meet the above conditions, the convex texture 13 or the concave texture 12 can be more complete after molding, and the appearance effect is better. Moreover, the convex texture 13 or the concave texture 12 does not completely affect the outer surface of the beads 11, that is, a part of the outer surface of the beads 11 is retained, and only the bead boundaries 111 are affected, so as to ensure the flatness of the outer surface of the trim body 1 while effectively adjusting the light reflected by the trim body 1.

[0049] In some embodiments of the present utility model, the outer surface has a plurality of convex textures 13, and at least two of the plurality of convex textures 13 are arranged crosswise, or the outer surface has a plurality of concave textures 12, and at least two of the plurality of concave textures 12 are arranged crosswise, or the outer surface has a plurality of convex textures 13 and a plurality of concave textures 12, and at least one of the plurality of convex textures 13 is arranged crosswise with at least one of the plurality of concave textures 12. That is to say, various arrangements of the convex textures 13 or the concave textures 12 can be made on the outer surface of the trim body 1, which can cause refraction of light in more directions, so as to better enhance the visual texture. In addition, a pattern can be constructed on the outer surface of the trim body 1 through the convex texture 13 or the concave texture 12, so that the outer surface of the trim body 1 is more visually beautiful.

[0050] In some embodiments of the present utility model, the thickness H3 of the trim body 1 satisfies: 6 mm ≤ H3 ≤ 12 mm. Through the design of the thickness of the trim body 1, not only can the cost be better reduced, but also the trim body 1 can be better within a suitable structural strength range to meet the requirements of the vehicle. Optionally, the thickness H3 of the trim body 1 can be 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc., and the present application does not make any restrictions.

[0051] In some embodiments of the present utility model, a plurality of reinforcing ribs 2 are integrally formed on the inner surface of the trim body 1, and the plurality of reinforcing ribs 2 are arranged crosswise.

[0052] In some embodiments of the present utility model, the thickness H4 of the reinforcing rib 2 satisfies: 20 mm ≤ H4 ≤ 30 mm. Through the design of the thickness of the reinforcing rib 2, not only can the cost be better reduced, but also the trim panel body 1 can be better within a suitable structural strength range, so as to meet the requirements of the vehicle. Optionally, the thickness H4 of the reinforcing rib 2 can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, etc., and the present application does not make any restrictions.

[0053] The width W of the reinforcing rib 2 is 10 mm ≤ W ≤ 20 mm. Thus, through the design of the width of the reinforcing rib 2, not only can the cost be better reduced, but also the trim panel body 1 can be better within a suitable structural strength range, so as to meet the requirements of the vehicle. Optionally, the width W of the reinforcing rib 2 can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, etc., and the present application does not make any restrictions.

[0054] In some embodiments of the present utility model, as Figure 5 shown, the vehicle interior trim panel 100 includes: a plurality of clamping members 3, and the clamping members 3 are embedded in the trim panel body 1.

[0055] Exemplarily, the clamping member 3 can be a metal part or a plastic part. When constructing the trim panel body 1 through the foaming process, the clamping member 3 can be placed at a predetermined position in the mold in advance. Thus, after the trim panel body 1 is foamed and formed, the clamping member 3 is embedded in the trim panel body 1, and the clamping member 3 can be better detachably connected to the vehicle body sheet metal. Here, it should be noted that the clamping member 3 can also be made of other materials, and the materials of the plurality of clamping members 3 can also be different, so as to meet the stress requirements at different positions.

[0056] In some embodiments of the present utility model, as Figure 5 shown, the vehicle interior trim panel 100 further includes a plurality of screwing members 4, and the screwing members 4 are embedded in the trim panel body 1. That is to say, when constructing the trim panel body 1 through the foaming process, the screwing members 4 can be placed at a predetermined position in the mold in advance. Thus, after the trim panel body 1 is foamed and formed, the screwing members 4 are embedded in the trim panel body 1, and the screwing members 4 can be better detachably connected to the vehicle body sheet metal through screws.

[0057] The present utility model also proposes a vehicle having the vehicle interior trim panel 100 of the above embodiments.

[0058] A vehicle according to an embodiment of the present utility model includes a body sheet metal and a vehicle interior trim panel 100, and the vehicle interior trim panel 100 is detachably mounted on the body sheet metal. By providing the vehicle interior trim panel 100 of the above embodiment, the vehicle interior trim panel 100 has good structural strength, good surface quality, and is relatively light in weight, which can not only improve the aesthetics inside the vehicle, but also effectively improve the comfort and safety of riding or living.

[0059] In some embodiments of the present utility model, there are multiple vehicle interior trim panels 100. Two adjacent ones of the multiple vehicle interior trim panels 100 are a first interior trim panel and a second interior trim panel. The first interior trim panel has a first folding edge, the second interior trim panel has a second folding edge, the first folding edge and the second folding edge are abutted, and at least one of the first folding edge and the second folding edge is further formed with a limiting portion, and the limiting portion is used to limit the relative position between the first folding edge and the second folding edge.

[0060] The first interior trim panel may be an upper C-pillar trim panel, and the second trim panel may be a lower C-pillar trim panel. The lower end of the upper C-pillar trim panel has a first folding edge, and the upper end of the lower C-pillar trim panel has a second folding edge. The upper and lower abutment of the first folding edge and the second folding edge can realize the up-and-down splicing of the upper C-pillar trim panel and the lower C-pillar trim panel. Since both the upper C-pillar trim panel and the lower C-pillar trim panel are integrally formed by a foaming material, therefore, the first folding edge can be preferably constructed on the upper C-pillar trim panel, and the second folding edge can be preferably constructed on the lower C-pillar trim panel. And, since the upper C-pillar trim panel and the lower C-pillar trim panel have concave textures 12 and / or convex textures 13, therefore, the upper C-pillar trim panel and the lower C-pillar trim panel can both have good visual textures.

[0061] The second folding edge has a bending structure that bends upward, and the bending structure can be configured as a limiting portion, and the limiting portion can limit the position of the first folding edge, so that the upper C-pillar trim panel and the lower C-pillar trim panel can be better spliced up and down.

[0062] Exemplarily, the vehicle interior trim panel may also be a trim panel at other parts inside the vehicle, such as Figure 5 the shown trim panel body 1 or as Figure 6 the shown trim panel body 1, and the present application does not make any restrictions.
