[0026] Next, refer to Figure 1 - Figure 2 Describe the vehicle interior trim panel 100 according to an embodiment of the present invention.

[0027] As Figure 1As shown in the figure, 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 foaming material. Compared with an injection molded part, the trim panel body 1 made of foaming material through a foaming process has a small density and high structural strength, which can effectively reduce the weight of the trim panel body 1 and achieve a lightweight design. Moreover, the trim panel body 1 made of foaming material also has good sound insulation, heat insulation and shock absorption characteristics. In addition, the foaming material is processed into the trim panel body 1 through processes such as molding, cutting, and bonding. Compared with the surface defects such as sink marks that are likely to occur on the surface of an injection molded part, the surface flatness of the trim panel body 1 is better, which can not only improve the aesthetics inside the vehicle, but also effectively improve the comfort and safety of riding or living.

[0028] Furthermore, during the process of manufacturing the trim panel body 1 from foaming material, ribs 2 can also be formed on the trim panel body 1 to improve the structural strength of the trim panel body 1. Here, it can be understood that the ribs 2 can be provided on the surface of one side of the trim panel body 1, and the ribs 2 can also be provided on the surfaces of both sides of the trim panel body 1.

[0029] Of course, it can be understood that other strengthening structures can also be provided on the trim panel body 1. For example, metal ribs can be embedded in the trim panel body 1, or the thickness can be increased in the stress concentration area of the trim panel body 1, etc. This application does not make any restrictions.

[0030] For the vehicle interior trim panel 100 according to an embodiment of the present utility model, by integrally forming the trim panel body 1 from foaming material, the structural strength of the trim panel body 1 can be better improved, the weight of the trim panel body 1 can be reduced, and moreover, not only can the aesthetics inside the vehicle be improved, but also the comfort and safety of riding or living can be effectively improved. By providing ribs 2 on the trim panel body 1, the structural strength of the trim panel body 1 can be further improved.

[0031] In some embodiments of the present utility model, the rib 2 includes a plurality of first ribs 21 extending in a first direction and a plurality of second ribs 22 extending in a second direction. The plurality of first ribs 21 and the plurality of second ribs 22 form a grid-like rib network on the surface of the trim panel body 1, wherein an included angle exists between the first direction and the second direction.

[0032] Refer to the attached Figure 1 In a specific example shown in the figure, the first direction and the second direction are perpendicular. The first rib 21 extends in the left-right direction, and the second rib 22 extends in the up-down direction. Thus, the grids within the rib network formed after the intersection of the first rib 21 and the second rib 22 are rectangular grids. When the outer peripheral edge of the trim panel body 1 has a flange 11, both the first rib 21 and the second rib 22 extend onto the flange 11, thereby improving the structural strength of the trim panel body 1.

[0033] Optionally, the first direction and the second direction may not be perpendicular to each other. For example, the included angle between the first reinforcing rib 21 and the second reinforcing rib 22 is an acute angle. Thus, the grids within the reinforcing rib network formed after the intersection of the first reinforcing rib 21 and the second reinforcing rib 22 are diamond-shaped grids. Optionally, two adjacent second reinforcing ribs 22 are not parallel. Thus, the grids within the reinforcing rib network formed after the intersection of the first reinforcing rib 21 and the second reinforcing rib 22 are trapezoidal or triangular grids. It can be understood that the grids within the reinforcing rib network formed after the intersection of the first reinforcing rib 21 and the second reinforcing rib 22 may also be other shapes, which are not limited in this application.

[0034] In some embodiments of the present utility model, in a third direction perpendicular to the first direction and the second direction, the thicknesses of both the first reinforcing rib 21 and the second reinforcing rib 22 are greater than the thickness of the trim panel body 1. Here, referring to Figure 1 as shown, the third direction is the thickness direction of the trim panel body 1. By making the thicknesses of both the first reinforcing rib 21 and the second reinforcing rib 22 greater than the thickness of the trim panel body 1, compared with injection-molded parts, when the thickness of the reinforcing rib 2 on the surface of an injection-molded part is greater than the thickness of its plate body, it is likely to cause uneven filling and inconsistent cooling of the reinforcing rib 2, thus easily affecting the surface quality of the injection-molded part. Moreover, it is also likely to increase the production difficulty and reject rate of the injection-molded part. In this application, however, the trim panel body 1 is made of a foaming material. Therefore, even if the thickness of the reinforcing rib 2 integrally formed on the trim panel body 1 is designed to be relatively large, it can still better ensure the surface quality of the vehicle interior trim panel 100. In addition, the production difficulty is low and the yield rate is high. Moreover, by increasing the thicknesses of the first reinforcing rib 21 and the second reinforcing rib 22 and extending both the first reinforcing rib 21 and the second reinforcing rib 22 to the flanging 11, the structural strength of the trim panel body 1 can be better improved.

[0035] Optionally, in the third direction, the thicknesses of both the first reinforcing rib 21 and the second reinforcing rib 22 are less than the thickness of the flanging 11.

[0036] In some embodiments of the present utility model, in the third direction, the first reinforcing rib 21 inclines towards one side in its width direction, and / or the second reinforcing rib 22 inclines towards one side in its width direction.

[0037] Referring to Figure 2As shown, the third direction is the thickness direction of the trim panel body 1. The reinforcing rib 2 is inclined downward during its extension in the thickness direction. Thus, an acute angle is formed between the reinforcing rib 2 and the trim panel body 1. The inclined reinforcing rib 2 can more effectively transfer the load from one direction to another, especially in a structure under a complex stress state. This can help disperse the stress, reduce the stress concentration in a local area, and improve the stability and durability of the overall structure. In the structural deformation caused by dynamic load or temperature change, the inclined reinforcing rib 2 can provide better adaptability. They can adjust the angle with the slight deformation of the main structure, which helps to maintain the overall integrity of the structure. Under specific design conditions, the inclined reinforcing rib 2 can utilize materials more efficiently, especially for the cases where the space is limited or the structure needs to be strengthened in multiple dimensions. This layout can ensure sufficient support in the key areas while reducing unnecessary material accumulation.

[0038] In some embodiments of the present utility model, the thickness H1 of the trim panel body 1 satisfies: 6 mm ≤ H1 ≤ 12 mm. Thus, through the design of the thickness of the trim panel body 1, not only can the cost be better reduced, but also the trim panel body 1 can be in a suitable structural strength range, so as to meet the requirements of the vehicle. Optionally, the thickness H1 of the trim panel body 1 can be 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc., and this application does not make any restrictions.

[0039] In some embodiments of the present utility model, the thickness H2 of the reinforcing rib 2 satisfies: 20 mm ≤ H2 ≤ 30 mm. Thus, 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 in a suitable structural strength range, so as to meet the requirements of the vehicle. Optionally, the thickness H2 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 this application does not make any restrictions.

[0040] In some embodiments of the present utility model, 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 in a suitable structural strength range, so as to meet the requirements of the vehicle. Optionally, the thickness H2 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 this application does not make any restrictions.

[0041] In some embodiments of the present utility model, such as Figure 1As shown, the vehicle interior trim panel 100 includes: a plurality of first clamping members 31 and at least one second clamping member 32. Both the first clamping members 31 and the second clamping members 32 are embedded in the trim panel body 1. Among them, the plurality of first clamping members 31 are arranged at intervals along the outer periphery of the trim panel body 1, and the second clamping members 32 are arranged in the middle area of the trim panel body 1.

[0042] Optionally, as Figure 1 shown, both the first clamping members 31 and the second clamping members 32 can be metal parts. When constructing the trim panel body 1 through the foaming process, the first clamping members 31 and the second clamping members 32 can be pre-placed at predetermined positions in the mold. Thus, after the trim panel body 1 is foamed and formed, both the first clamping members 31 and the second clamping members 32 are embedded in the trim panel body 1. Through the first clamping members 31 and the second clamping members 32, the trim panel can be detachably connected to the vehicle body sheet metal better. Here, it should be noted that the first clamping members 31 and the second clamping members 32 can also be made of other materials, and the materials of the first clamping members 31 and the second clamping members 32 can also be different, so as to meet the stress requirements at different positions.

[0043] Optionally, as Figure 1 shown, the outer peripheral edge of the trim panel body 1 is provided with a flanging 11, and some of the first clamping members 31 are located at the folding position of the flanging 11. That is to say, only some of the first clamping members 31 can be located at the folding position of the flanging 11, or all of the first clamping members 31 can be arranged at intervals along the folding position of the flanging 11. By arranging the first clamping members 31 at the folding position of the flanging 11, the structural strength at the folding position can be improved, and stress concentration at the folding position can be avoided and damage can be prevented.

[0044] In some embodiments of the present invention, as Figure 1 shown, the vehicle interior trim panel 100 further includes a plurality of screwing members 33, and the screwing members 33 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 33 can be pre-placed at predetermined positions in the mold. Thus, after the trim panel body 1 is foamed and formed, the screwing members 33 are embedded in the trim panel body 1. Through the screwing members 33, the trim panel can be detachably connected to the vehicle body sheet metal by screws better.

[0045] In some embodiments of the present invention, the trim panel body 1 is made of EPP material by foaming. The density of the traditional injection molded part is 1050 kg / m 3 , and the density of the trim panel body 1 made of EPP material by foaming is 60 kg / m 3 - 90 kg / m 3 , which can greatly increase the wall thickness of the parts without increasing the weight, thus being beneficial to the lightweight design of the trim panel body 1.

[0046] The present utility model further provides a vehicle having the vehicle interior trim panel 100 of the above embodiment.

[0047] The vehicle according to the embodiment of the present utility model includes a vehicle body sheet metal and a vehicle interior trim panel 100, and the vehicle interior trim panel 100 is detachably mounted on the vehicle 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.
