[0031] Example

[0032] Please refer to Figure 1 As shown, the vehicle B-pillar interior panel provided in the embodiment of the present invention, wherein the interior panel 100 includes a main board 1, and the main board 1 is provided with a fastener for fixing the interior panel 1 to the B-pillar 200 (such as Figure 6and for the seat belt (not shown) with the installation of the seat belt through hole 5; side panels 2, the side panels 2 are formed in the longitudinal direction of the side of the main board 1 (such as Figure 2 As shown in the figure, a plurality of reinforcing ribs 6 are evenly arranged along the length direction of the side panel 2 for reinforcing the overall strength of the interior panel 100. The reinforcing ribs 6 are formed on the side panel and extend to the main panel. The material of the interior panel 100 is expanded polypropylene (EPP) with a foaming ratio in the range of 10-15 times.

[0033] In this embodiment, Figure 1 and Figure 5 As shown, the thickness of the top 10 of the interior panel gradually decreases upwards to be installed in conjunction with the ceiling of the B-pillar 200. The height of the inner surface 11 of the interior panel is lower than the height of the outer surface 12. A connecting surface 13 is formed between the top of the inner surface 11 of the interior panel and the top of the outer surface 12 of the interior panel. The connecting surface 13 forms a thinning angle α with the plane where the outer surface 12 of the interior panel is located. The thinning angle α is 40°.

[0034] In this embodiment, Figure 1 and Figure 3 As shown, the mounting holes include bolt fixing holes 3 located at the upper portion of the main board 1 and snap-in holes 4 located at the lower portion of the main board 1. The bolt fixing holes 3 are used to connect to the upper portion of the B-pillar 200 via fasteners, and the snap-in holes 4 are used to connect to the lower portion of the B-pillar 200 via fasteners. Figure 6 As shown, the fastener includes a bolt 31 mounted in cooperation with the bolt fixing hole 3 and a buckle 42 mounted in cooperation with the clamping hole 4 .

[0035] In this embodiment, the surface of the interior panel 100 is further connected to the fabric layer (not shown) via an adhesive layer (not shown). Specifically, the outer surface 12 of the interior panel can be bonded to the decorative fabric layer using a colloid such as glue, double-sided tape, or structural adhesive.

[0036] In this embodiment, Figure 4 As mentioned above, a support rib 41 is provided in the snap-fit hole 4 , and the support rib 41 is used to support the interior trim panel 100 on the B-pillar 200 .

[0037] In this embodiment, the diameter of the bolt fixing hole 3 is in the range of 9-11 mm. Preferably, in this embodiment, the diameter of the bolt fixing hole 3 is 10 mm. The diameter of the clamping hole 4 is in the range of 8-9 mm. Preferably, in this embodiment, the diameter of the clamping hole 4 is 8.5 mm. The thickness of the main board 1 is in the range of 9-11 mm. Preferably, in this embodiment, the thickness of the main board 1 is 10 mm. The thickness of the side panel 2 gradually decreases in the direction away from the main board 1 (e.g., Figure 2As shown), the thickness of the side panel 2 ranges from 8 to 15 mm. Preferably, the thickness of the side panel 2 where it connects to the main board 1 is 15 mm, and the thickness at the farthest end away from the main board 1 is 8 mm.

[0038] This embodiment also provides a vehicle, which includes a vehicle B-pillar interior panel as described in any one of the above.

[0039] The following description will further explain the characteristics and functions of the present invention.

[0040] The vehicle B-pillar interior panel of this embodiment reduces component surface hardness and mitigates impact. Existing PP trim panels can achieve a surface hardness of up to 48 Rockwell hardness, while the panel of this embodiment is entirely constructed from EPP with a 10-15 expansion ratio. The EPP is a gas composite material, and the air filling ratio of a 10-fold expansion ratio product is over 90%. While its surface hardness is lower, it provides excellent impact cushioning. Preferably, the panel of this embodiment can be thickened to the vehicle body's sheet metal surface in the head impact area. Existing PP B-pillar trim panels are currently limited to 2.5-3.0 mm in thickness due to cosmetic defects, which prevents further thickness increases and poses a risk of breakage. The EPP B-pillar trim of this embodiment has no such restrictions and can be thickened to the vehicle body's sheet metal surface, thus avoiding the problem of insufficient strength and fracture. Furthermore, the panel is foamed at a 10-15 expansion ratio, so even if it breaks, the fractured gap in the panel is soft, posing no physical risk to the driver or passengers.

[0041] When assembling the interior panel 100 of this embodiment, bolts 31 can be used to pass through the bolt fixing holes 3 of the interior panel 100, and then the interior panel 100 can be screwed and fixed to the B-pillar 200 of the vehicle body. The lower part of the interior panel 100 is fixed to the snapping holes 4 at the lower part of the interior panel 100 through two clips 42, and then the interior panel 100 can be snapped and fixed to the B-pillar 200 of the vehicle body.

[0042] The above-mentioned fixed assembly is completed, and the driver and passengers are protected from physical damage by the low surface hardness of the B-pillar interior panel 100 or the soft fracture cross-section after fracture.

[0043] In summary, the vehicle B-pillar interior panels provided by this utility model utilize expanded polypropylene with a foaming ratio of 10-15 times. While having a relatively low overall hardness, they maintain their strength and provide excellent cushioning, effectively reducing the risk of the B-pillar interior panel rupturing and injuring the driver or passenger's head in the event of a collision. Furthermore, due to the use of expanded polypropylene, the surface color of the panels resembles soft interior, enhancing the quality of the vehicle interior.

[0044] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
