Specifically, the handrail 30 is also installed on the inner side surface of the lower trim panel 40, so that a user can push and pull the vehicle door through the handrail 30, the second lightening hole 42 is formed in the lower trim panel 40, the second lightening hole 42 can further lighten the lower trim panel 40, accordingly, the weight of the vehicle door trim panel assembly 100 is lower, the light weight design of the vehicle door trim panel assembly 100 can be better achieved, meanwhile, the projection of the handrail 30 in the direction perpendicular to the lower trim panel 40 can shield the second lightening hole 42, the second lightening hole 42 is not directly visible, the use experience of the user is facilitated to be enhanced, the second reinforcing rib is arranged at the edge of the second lightening hole 42, the second reinforcing rib can play a role in structurally reinforcing the second lightening hole 42, and accordingly, the lower trim panel 40 can be structurally reinforced, and after being perforated, the vehicle door trim panel assembly is also provided with sufficient structural strength.

It should be noted that, the setting positions of the second lightening holes 42 may be flexibly designed according to the installation positions of the armrests 30, and the number of the second lightening holes 42 may also be plural, so as to further reduce the weight of the lower trim panel 40, and the plurality of second lightening holes 42 may be spaced apart according to the corresponding positions of the armrests 30 on the lower trim panel 40, where the arrangement direction of the plurality of second lightening holes 42 is not limited.

In some embodiments, as shown in fig. 2-8, the first and second reinforcing ribs are each configured as a reinforcing flange 43, the reinforcing flange 43 being folded over in a direction away from the interior side of the lower trim panel 40.

Thereby, the structural strength of the lower decoration plate 40 is enhanced, the torsional strength of the lower decoration plate 40 caused by the arrangement of the first lightening holes 41 and/or the second lightening holes 42 is reduced, and the reinforcing flange 43 is folded towards the direction deviating from the inner side surface of the lower decoration plate 40, so that the influence of the reinforcing flange 43 on the installation of the decoration plate assembly 20 and the handrail 30 can be avoided

After the weight reduction treatment (the provision of the first weight reduction hole 41 and/or the second weight reduction hole 42) is performed on the lower trim 40, the structural strength of the lower trim 40 may be reduced, and thus, the structural reinforcement of the lower trim 40 is required.

For example, the edge of the first lightening hole 41 is provided with a reinforcing flange 43, the reinforcing flange 43 is turned towards the direction away from the inner side of the lower decorative plate 40, or the edge of the second lightening hole 42 is provided with a reinforcing flange 43, the reinforcing flange 43 is turned towards the direction away from the inner side of the lower decorative plate 40, or the first lightening hole 41 and the second lightening hole 42 are both provided with reinforcing flanges 43, and the reinforcing flange 43 is turned towards the direction away from the inner side of the lower decorative plate 40, preferably, in this embodiment, the first lightening hole 41 and the second lightening hole 42 are both provided with reinforcing flanges 43.

Therefore, by providing the reinforcing flange 43 at the edges of the first lightening hole 41 and the second lightening hole 42, the structural strength of the lower trim 40 can be enhanced and the torsional strength of the lower trim 40 due to the perforation can be weakened, and the reinforcing flange 43 is folded away from the inner side surface direction of the lower trim 40, so that the reinforcing flange 43 does not interfere with the mounting of the trim assembly 20 and the armrest 30.

It should be noted that, since the decorative board assembly 20 and the armrest 30 have a surface difference between the decorative board assembly 20 and the mounting surface of the lower decorative board 40 and the armrest 30 and the mounting surface of the lower decorative board 40 when being mounted on the lower decorative board 40, the decorative board assembly 20 is mounted on the board body 45 and the armrest 30 is connected to the mounting boss 46, so that the decorative board assembly 20 and the armrest 30 can be mounted on the lower decorative board 40.

Thus, the mounting boss 46 enables the armrest 30 to be mounted on the lower trim panel 40 without interference from the trim panel assembly 20.

In some embodiments, as shown in fig. 5 and 7, the lower fascia 40 further includes support ribs 44, the support ribs 44 being connected between mounting bosses 46 and the fascia body 45.

It should be noted that, when the mounting boss 46 in the lower trim panel 40 is connected to the armrest 30, it protrudes from the panel body 45, so that it is difficult to ensure the structural strength of the mounting boss 46, so that the supporting reinforcing rib 44 is disposed between the mounting boss 46 and the panel body 45, and the supporting reinforcing rib 44 can maintain the strength of the mounting boss 46 to ensure the mounting strength of the armrest 30.

Therefore, the strength of the mounting boss 46 can be enhanced by arranging the supporting reinforcing ribs 44, so that the mounting boss has enough strength to ensure the stability of the armrest 30 after being connected with the armrest 30, a plurality of supporting reinforcing ribs 44 can be arranged at intervals between the mounting boss 46 and the plate body 45, the consumption of materials is saved, the weight of the lower decorative plate 40 is reduced as much as possible under the premise of ensuring the strength, and the weight of the vehicle door decorative plate assembly 100 is better.

In some embodiments, as shown in fig. 5, the minimum distance between the mounting boss 46 and the reinforcing flange 43 is a, and satisfies: a is less than or equal to 2 mm; and/or the mounting boss 46 is provided with a mounting hole for connection with the armrest 30, and in the radial direction of the mounting hole, the geometric center of the mounting hole is at a distance B from the edge of the mounting boss 46, and satisfies: b is more than or equal to 7 mm.

Specifically, in order to ensure the effect of reinforcing the structural strength of the lower decorative plate 40 by the reinforcing flange 43, the distance between the mounting boss 46 and the reinforcing flange 43 is limited, the minimum distance between the mounting boss 46 and the reinforcing flange 43 is a, and a is 2mm or less than a, so that the value of a can be a=2 mm, or a=2.5 mm, or a=3 mm, and the distance between the mounting boss 46 and the reinforcing flange 43 can be controlled by limiting a, so that the effect of reinforcing the structural strength of the lower decorative plate 40 by the reinforcing flange 43 is ensured.

Alternatively, the distance between the geometric center of the mounting hole of the mounting boss 46 for mounting the handrail 30 in the radial direction and the edge of the mounting boss 46 may be defined, the distance between the geometric center of the mounting hole in the radial direction and the edge of the mounting boss 46 is B, and B satisfies 7mm and less than or equal to B, so that the value of B may be b=7 mm, or b=7.5 mm, or b=8 mm, and by defining B, the distance between the mounting hole of the mounting boss 46 and the edge of the mounting boss 46 may be kept, so that the connection strength of the handrail 30 after being mounted to the mounting boss 46 is higher, and the breakage of the mounting hole may be reduced.

Preferably, in the present embodiment, 2 mm. Ltoreq.A and 7 mm. Ltoreq.B are satisfied simultaneously, which makes the connection strength of the armrest 30 after being mounted to the mounting boss 46 higher and enables breakage of the mounting hole to be reduced.

By defining the minimum distance a between the mounting boss 46 and the reinforcing flange 43 and the distance B between the geometric center of the mounting hole of the mounting boss 46 in the radial direction and the edge of the mounting boss 46, it is thereby possible to make the reinforcing flange 43 more effective in structurally reinforcing the lower trim 40, while making the connection strength of the armrest 30 higher when mounted to the mounting boss 46.

In some embodiments, as shown in fig. 5 and 8, the reinforcing bead 43 has a height H in a direction perpendicular to the lower trim panel 40, and satisfies: h is more than or equal to 4 mm; and/or the width of the reinforcing bead 43 in a direction parallel to the lower trim panel 40 is D, and satisfies: d is less than or equal to 2 mm.

Specifically, in order to make the reinforcing effect of the reinforcing bead 43 better, the size of the reinforcing bead 43 itself is limited, for example, in the direction perpendicular to the lower trim panel 40, the height of the reinforcing bead 43 is H, and H satisfies 4mm r.t., so the value of H may be h=4 mm, or h=4.5 mm, or further, h=5 mm, or in the direction parallel to the lower trim panel 40, the width of the reinforcing bead 43 is D, and D satisfies 2mm r.t., so the value of D may be d=2 mm, or d=2.5 mm, further, or d=3 mm, and in various embodiments, satisfies 4mm r.t.h, or satisfies 2mm r.t.d, and further, or 4mm r.t.h and 2mm r.t.d satisfy simultaneously, and preferably, in this embodiment, 4mm r.t.h and 2mm r.t.d satisfy simultaneously.

By limiting the height and width of the reinforcing flange 43, the reinforcing flange 43 provides a better reinforcing effect when the lower trim 40 is structurally reinforced.

In some embodiments, as shown in fig. 1-2, trim panel assembly 20 includes trim panel 21 and center trim panel 22, first lightening hole 41 includes a first sub-hole 411 and a second sub-hole 412, a middle region of trim panel 21 is opposite first sub-hole 411, and a middle region of center trim panel 22 is opposite second sub-hole 412.
