Next, embodiments of the present specification will be described in detail.

Referring to fig. 1 to 4, the present utility model provides a sealing structure for a door trim panel, which includes a trim panel 10, a sealing member 20 and a reinforcing plate 30, wherein the trim panel 10 is connected with the reinforcing plate 30, and the sealing member 20 is located between the trim panel 10 and the reinforcing plate 30. The sealing member 20 is provided with a protruding rib 21 at a surface opposite to the trim 10, and the protruding rib 21 is interference fit with the trim 10 to improve sealing performance of the sealing structure of the door trim. Thus, the pressure of the oncoming wind in the running process of the vehicle is prevented from exceeding the sealing resistance of the door trim and entering the vehicle, thereby preventing wind noise and preventing water leakage and ash leakage.

The trim 10 is provided with a mating portion (not shown) on a surface thereof which is closely attached to the seal 20, and correspondingly, the seal 20 is also provided with a positioning portion 22, and the mating portion is connected with the positioning portion 22 to position the mount seal 20, and also serves as a connection member for connecting the trim 10 with the reinforcing plate 30. The mating portion is a stud, and the positioning portion 22 is a through hole. When the seal member is installed, the seal member 20 can be directly sleeved on the decoration plate 10 by connecting the matching part with the positioning part 22, and the decoration plate 10 is fixed with the reinforcing plate 30, so that the operation is simple and convenient.

The decoration plate 10 comprises an outer decoration plate 11 and an inner decoration plate 12, and the outer decoration plate 11 and the inner decoration plate 12 are molded by double injection. The outer decorative plate 11 may be made of a material having a good appearance quality, and the inner decorative plate 12 may be made of a material having a low cost. Thus, the dual-layer plaque increases the hardness of the plaque 10, and simultaneously reduces the cost and improves the appearance quality.

In this embodiment, the outer decoration plate 11 is made of PMMA (Polymethyl methacrylate, acryl) and the inner decoration plate 12 is made of ABS (Acrylonitrile Butadiene Styrene ). Wherein, PMMA has good light transmittance, high cost, high strength of ABS and low cost.

In alternative embodiments, the outer layer decoration board 11 may be made of other materials such as PC (Polycarbonate) or PE (Polyethylene), and the inner layer decoration board 12 may be made of other materials such as PS (Polystyrene) or POM (polyoxymethylene).

One side of the seal 20 is against the fascia 10 and the opposite side is against the reinforcing plate 30. The sealing member 20 may be directly connected to the trim panel 10 through the positioning portion 22 and the mating portion, and then clamped by the reinforcing plate 30. The sealing member 20 may be directly disposed between the decoration plate 10 and the reinforcing plate 30 by other connection methods such as gluing, and the adhesive strength may be increased based on the connection between the positioning portion 22 and the mating portion.

The shape of the seal 20 is adapted to the shape of the plaque 10, and may be triangular or other irregular polygonal shape. The sealing member 20 may be foam, rubber pad, or the like, and may be capable of achieving a sealing function. The height of the raised ribs 21 ranges from 2 mm to 5 mm, so that the surface contact of the decoration plate 10 and the sealing element 20 is changed into line contact, the sealing performance is improved, and the weight is reduced. In some embodiments, the height of the raised ribs 21 may be 2 mm, 3 mm, 4 mm, 5 mm, or some value between any two adjacent ones of the above. In this embodiment, the height of the protruding ribs 21 is 3 mm.

Specifically, the protruding rib 21 includes a first rib 211 and a second rib 212. The first rib 211 is disposed at an edge of the sealing member 20, and the second rib 212 is disposed within the first rib 211 and connected to the first rib 211. The protruding ribs 21 are arranged at the periphery and the connection part of the boundary of the structure, the matching degree of parts overlapped with the periphery is good, and tolerance to tolerance is higher than that of the traditional structure.

The first rib 211 encloses the first sealing area 40, and the second rib 212 and the first rib 211 together form the second sealing area 50. That is, the second sealing region 50 is located inside the first sealing region 40, and the second sealing region 50 is disposed around the positioning portion 22. The first sealing area 40 seals the edge of the decoration board 10 and the sealing piece 20, and the second sealing area 50 seals any hole or notch or the like formed on the sealing piece 20, especially the connection of the decoration board 10 and the sealing piece 20. Thus, the phenomena of air leakage and wind noise are further prevented, and meanwhile, the water and dust are prevented from entering.

One end of the trim 10, seal 20, and reinforcing plate 30 is connected to the first door frame seal 60, and the other end of the trim 10 and seal 20 is connected to the second door frame seal 70. In this embodiment, the first door frame seal 60 is an a-pillar seal and the second door frame seal 70 is an exterior water seal.

Referring to fig. 5, the present utility model further provides a vehicle door, including the sealing structure for a vehicle door trim panel as described above.

The utility model also provides a vehicle comprising the vehicle door.
