The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is an exploded view of an instrument panel assembly according to an embodiment of the present disclosure.

Referring to fig. 1, the present application provides an instrument panel assembly, including a main board 100, an airbag box 200 and a mounting bracket 300, where the airbag box 200 and the mounting bracket 300 are respectively connected to the inner side of the main board 100, and the main board 100 and the mounting bracket 300 are respectively of an integrally formed structure of a fibrilia composite material; the main plate 100, the airbag case 200, and/or the mounting bracket 300 each include a stiffener structure 400.

As can be seen from this embodiment, the main board 100 and the mounting bracket 300 are respectively made of an integrally molded structure of a hemp fiber composite material, and the structural strength of the main board 100 and the mounting bracket 300 can be enhanced by the reinforcing rib structure 400. Compare with the plastic construction that the instrument panel was made by the polypropylene material among the correlation technique, the instrument panel subassembly that this application provided can further realize the structure lightweight to, adopt fibrilia combined material's mainboard 100 and installing support 300 can not produce the closed angle after the fracture, can ensure the security after the collision fracture, avoid the interior personnel of secondary injury car.

It should be noted that the integrated structure of the fibrilia composite material can be integrally formed by compression molding, which is an operation of placing the fibrous fibrilia composite material into a mold cavity at a molding temperature, closing the mold and pressurizing to mold and cure the fibrous fibrilia composite material. The rib structure 400 can be formed on the integrated structure of the fibrilia composite material by two-step injection molding, which is also called injection molding, and is a molding method of injection and molding. The reinforcing rib structure 400 can be made of injection molding materials such as polypropylene and polyvinyl chloride to improve the strength of the integrated structure of the fibrilia composite material.

In this embodiment, after the fibrilia composite material is molded integrally, the mounting bracket 300 may be punched and trimmed twice to reserve device mounting openings for mounting devices such as an instrument and a central control large screen, so as to subsequently realize the assembly of devices in a vehicle body.

In this embodiment, the hemp fiber composite material includes one or more of jute, flax, hemp and kenaf. Hemp fiber is a generic term for fibers obtained from various hemp plants. Fibrilia is a wide variety of varieties including bast fibers and leaf fibers. Bast fiber crops mainly include ramie, jute, ramie, hemp (hemp), flax, kendir, kenaf and the like. The cellulose content in the chemical components of various fibrilia is about 75 percent, and the proportion of the cellulose content in the silk fiber is similar to that of the fiber content in the silk fiber, so the fibrilia is light, and the main board 100 and the mounting bracket 300 which are integrally formed by fibrilia composite materials can further realize light weight. Meanwhile, the fibrilia is a high-strength low-elongation type fiber, is not easy to deform, and can form various structural members for constructing the instrument panel assembly, such as the main board 100 and the mounting bracket 300, under a molding process. In this embodiment, the mounting bracket 300 may also be referred to as a skeleton.

The bast fiber is the basic skeleton of plant and has high crystallinity and orientation degree, and the fibril is distributed in the radial direction of the fiber in layered structure. For example, flax has a crystallinity of 90% and an orientation of approximately 80%. Because the fibrilia has high crystallinity and orientation, the fibrilia is the fiber with the lowest breaking elongation of all fibers, so that the integrated structure of the fibrilia composite material does not have brittle fracture to generate sharp corners and has better safety.

In addition, the instrument panel in the related art is mainly made of polypropylene material, polypropylene is abbreviated as PP, and the polypropylene material is a colorless, odorless, nontoxic and semitransparent solid substance. Polypropylene is a thermoplastic synthetic resin with excellent performance, and is colorless translucent thermoplastic light general-purpose plastic. The polypropylene has chemical resistance, heat resistance, electrical insulation, high-strength mechanical property, good high-wear-resistance processing property and the like, so that the polypropylene can be rapidly and widely developed and applied in a plurality of fields such as machinery, automobiles, electronic and electric appliances, buildings, textiles, packaging, agriculture, forestry, fishery, food industry and the like since the coming out. However, the instrument panel made of polypropylene material has the disadvantages of being difficult to recycle and not environmentally friendly. The application provides an instrument panel assembly uses fibrilia combined material integrated into one piece, can carry out recycle through smashing into the aggregate to can solve the defect that the instrument panel is difficult to retrieve, not environmental protection among the correlation technique.
