[0033] A common source of unusual noise in vehicle interiors is friction between the upper pillar trim and the ceiling trim panel. To address this issue, this application provides an improved upper pillar trim, including but not limited to the A-pillar, B-pillar, C-pillar, and D-pillar trims. This application uses the C-pillar trim as an example for illustration.

[0034] Figure 1 This is a schematic diagram of the outer structure of a C-pillar upper trim panel 10 provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the inner structure of a C-pillar upper trim panel 10 provided in an embodiment of the present application. Figure 1 and Figure 2 As shown, an embodiment of the present application provides a C-pillar upper trim panel 10 , which includes a trim panel body 11 .

[0035] The trim panel body 11 has an outer surface and an inner surface, corresponding to the outer and inner sides of the vehicle body, respectively. At least a portion of the upper edge of the outer surface is an overlapping region for overlapping with the interior ceiling panel. The overlapping region extends along at least a portion of the upper edge and has a certain width.

[0036] It should be noted that the width of the overlapping area generally refers to the actual width when the trim panel body 11 overlaps with the ceiling interior panel. Generally speaking, this actual width is greater than the design width. During design, the width of the overlapping area can be designed according to the specific overlapping requirements of the C-pillar upper trim panel and the ceiling interior panel of different cars, and the designed width can be used as a reference value. During actual assembly, since the C-pillar upper trim panel 10 and the ceiling interior panel need to be squeezed and installed to eliminate the gap, the actual width of the overlapping area will be slightly greater than the design width. For example, the design width of the overlapping area is 1mm. When the C-pillar upper trim panel 10 overlaps with the ceiling interior panel, the actual width of the overlapping area is about 5mm due to the mutual squeezing between the C-pillar upper trim panel 10 and the ceiling interior panel.

[0037] The trim panel body 11 is provided with a grained surface 12 that covers at least the overlap area. When the C-pillar upper trim panel 10 overlaps the ceiling interior panel, the grained surface 12 increases friction and adhesion at the joint between the two panels, reducing the likelihood of noise or creaking due to friction between the two panels.

[0038] The grained surface 12 can be produced through hot pressing, embossing, chemical etching, or other surface treatment processes. For example, the panel body 11 is a plastic part molded by injection molding, and the grained surface 12 is chemically etched at the location on the mold corresponding to the grained surface 12. During production, the panel body 11 and its grained surface 12 are integrally formed, eliminating the need for secondary processing of the panel body 11 to form the grained surface 12. This processing method not only saves production time and cost, but also avoids surface damage that may be caused by secondary processing. Furthermore, this processing method can produce very fine textures.

[0039] The leather grain surface 12 can have the same texture as the fabric layer of the ceiling interior panel, so as to ensure that the overlapping position has the same texture as the fabric layer of the ceiling interior panel, while ensuring the overall aesthetics.

[0040] Because the C-pillar upper trim panel 10 and the ceiling interior panel need to be squeezed together to eliminate gaps during overlap, to ensure a better overlap, the width of the grained surface 12 must be greater than or equal to the width of the overlap area. Preferably, the width of the grained surface 12 can be 2-3 times the width of the overlap area. The thickness of the grained surface 12 must also be moderate. A grained surface 12 that is too thick may affect the function of the interior trim, while a grained surface that is too thin may not provide sufficient noise elimination and cushioning. Preferably, the thickness of the grained surface 12 can be 40-60 millimeters, or 0.4mm-0.6mm.

[0041] For example, the width of the overlapping area is 5 mm, the width of the leather grain surface 12 is 15 mm, and the thickness of the leather grain surface 12 is 50 mm, that is, 0.5 mm.

[0042] In addition, the wall thickness of the decorative plate body 11 is 2mm-2.5mm. Among them, the wall thickness of the main structural part can be 2.5mm to ensure sufficient strength, and the wall thickness of other structural parts can be adjusted between 2mm-2.5mm according to design requirements.

[0043] like Figure 1 As shown, the trim body 11 is also provided with a snap-on mounting portion 111, a positioning pin portion 112, and a bolt fixing hole 113. These structures are used for the installation of the trim body 11 and the body sheet metal. Among them, the snap-on mounting portion 111 is used to engage with the snap on the body sheet metal, the positioning pin portion 112 is used to insert into the positioning pin hole on the body sheet metal, and the bolt fixing hole 113 is used for the bolt to pass through to connect and fix with the body sheet metal. Exemplarily, the snap-on mounting portion 111 and the positioning pin portion 112 are arranged on the outer surface of the trim body 11, the number of the snap-on mounting portions 111 is three, the number of the positioning pin portions 112 is two, and the number of the bolt fixing holes 113 is three. For specific setting positions, please refer to Figure 1 , Figure 1 In the figure, three clip mounting parts 111 are respectively located at the upper and lower parts of the trim body 11, and the positions of the three clip mounting parts 111 roughly form a triangle, and the two positioning pin parts 112 are respectively located at the two opposite corners of the upper and lower parts of the trim body 11, and the three bolt fixing holes 113 are also respectively located at the upper and lower parts of the trim body 11, and the positions of the three clip bolt fixing holes 113 roughly form a triangle. Through the position arrangement of the above components, a firm connection can be provided between the trim body 11 and the vehicle body sheet metal.

[0044] Figure 3 This is a schematic diagram of the overall structure of a C-pillar upper trim panel 10 and a ceiling interior trim panel 20 provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the structure of the overlap of the fabric layer 22 of the C-pillar upper trim panel 10 and the ceiling interior panel 20 provided in the embodiment of the present application. Figure 3 and Figure 4 As shown, an embodiment of the present application provides a structure for overlapping a C-pillar upper trim panel 10 and a ceiling interior panel 20. The ceiling interior panel 20 includes a substrate 21 and a fabric layer 22. The substrate 21 has an outer surface and an inner surface, corresponding to the outer and inner sides of the vehicle body, respectively. The fabric layer 22 is disposed on the inner surface of the substrate 21 and, illustratively, is bonded to the substrate 21 using heat-compression bonding.

[0045] Figure 5 for Figure 4 A partial enlarged view of the middle A. Figure 4 and Figure 5As shown, when the C-pillar upper trim panel 10 overlaps with the ceiling interior panel 20, the leather surface 12 of the C-pillar upper trim panel 10 overlaps with the edge of the corresponding position of the fabric layer 22 of the ceiling interior panel 20. Specifically, the leather surface 12 and the edge of the corresponding position of the fabric layer 22 contact each other and overlap by a certain width.

[0046] The leather surface 12 can have the same texture as the fabric layer 22 of the ceiling interior panel 20. For example, the fabric layer 22 is a suede fabric. The leather surface 12 and the fabric layer 22 have the same texture, which can improve the quality of the car interior and meet consumers' pursuit of high-quality car interiors.

[0047] It should be emphasized that although the embodiments of this application only use the C-pillar upper trim panel 10 as an example, the present invention is not limited to the C-pillar upper trim panel 10. The structure of the C-pillar upper trim panel 10 can be applied to the A-pillar upper trim panel, the B-pillar upper trim panel, and the D-pillar upper trim panel, especially the design of the leather grain surface 12. Of course, the design needs to be appropriately adjusted according to the specific pillar upper trim panel.

[0048] Similarly, the overlapping structure of the C-pillar upper trim panel 10 and the ceiling interior panel 20 can be applied to the overlapping structure of the A-pillar upper trim panel and the ceiling interior panel, the overlapping structure of the B-pillar upper trim panel and the ceiling interior panel, and the overlapping structure of the D-pillar upper trim panel and the ceiling interior panel. That is to say, the embodiment of the present application actually provides a overlapping structure of the pillar upper trim panel and the ceiling interior panel.

[0049] An embodiment of the present application also provides a vehicle, which includes the above-mentioned overlapping structure of the pillar upper decorative panel and the ceiling interior decorative panel.

[0050] In summary, the pillar upper trim panel, the overlapping structure of the pillar upper trim panel and the ceiling interior panel, and the vehicle provided in the embodiments of the present application, by providing a leather-grained surface on the trim panel body of the pillar upper trim panel, and the leather-grained surface covering the overlapping area on the trim panel body for overlapping with the ceiling interior panel, can increase the friction and adhesion at the overlapping position between the pillar upper trim panel and the ceiling interior panel, and reduce the possibility of abnormal noise due to friction between the pillar upper trim panel and the ceiling interior panel, thereby effectively solving the abnormal noise problem at the overlapping position and ensuring the driving experience.

[0051] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the field can easily think of various changes or replacements within the technical scope disclosed in the present application, which should all be included in the scope of protection of the present application.
