It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] like Figures 1 to 7As shown, an automotive interior panel of this embodiment includes a bottom layer 1, a support layer 2, an isolation layer 3, and a cover layer 4. The support layer 2 is disposed on the bottom layer 1, which can be attached to a component 10 via an adhesive layer 5. The support layer 2 includes several support strips 21 protruding from the bottom layer 1, forming several spaced recesses 22 around it. The isolation layer 3 is disposed on the support layer 2, and is attached to the bottom layer 1 at the recesses 22, forming a concave-convex structure. During processing, adhesive is applied between the isolation layer 3 and the bottom layer 1, and vacuum suction is used to bond the isolation layer 3 and the bottom layer 1 together, thus eliminating the need for rolling and avoiding damage to the support layer. The cover layer 4 is disposed on the isolation layer 3, and is also bonded using adhesive and vacuum suction to prevent damage from rolling. The cover layer 4 is a decorative layer and can be made of materials such as EVA or genuine leather. The isolation layer 3 is made of fire-retardant material, thereby improving its flame-retardant capability. The isolation layer 3 includes a first yarn 31 and a second yarn 32. The first yarn 31 is wound into several spaced-apart first annular portions 33, and the second yarn 32 passes through the first annular portions 33 and is formed into several spaced-apart second annular portions 34. This technical solution allows the isolation layer to have a certain degree of elasticity, enabling it to conformably adhere to the support strip 21. In this technical solution, the support strip 21 enhances the structural stability of the interior panel and improves its impact resistance. Furthermore, the isolation layer 3 improves fire resistance and temperature resistance, thereby enhancing safety.

[0025] In this embodiment, the first yarn 31 includes reinforcing fibers 311 and regulating fibers 312 stacked together, and the second yarn 32 includes reinforcing fibers 321 and fire-retardant fibers 322 stacked together. The reinforcing fibers 311 strengthen the yarn structure, the regulating fibers 312 adjust the flexibility of the insulating layer, and the fire-retardant fibers 322 enhance the fire-retardant capability. In this embodiment, the weight of the reinforcing fibers 311 is 40% to 60% of the weight of the insulating layer. The reinforcing fibers 311 are glass fibers, the regulating fibers 312 are polyester, and the fire-retardant fibers 322 are flame-retardant fibers.

[0026] In another embodiment, the support strip 21 surrounds to form an annular portion 6, and a recessed portion 22 is located in the annular portion 6. A reinforcing strip 7 is provided in the middle of the recessed portion 22, and both ends of the reinforcing strip 7 are connected to the annular portion 6. By providing the reinforcing strip 7, the structural strength of the support layer can be further enhanced. The support layer 2 has at least two layers, and adjacent support layers 2 are separated by a bottom layer 1, thereby allowing multiple support layers to be set to improve structural stability. The bottom layer 1 can be made of the same material as the isolation layer 3, or it can be made of other materials. The reinforcing strips 7 of adjacent support layers 2 form an included angle α, thereby enabling the support strips to be arranged in an alternating manner to improve support performance. For example, reinforcing strips 71 and 72 are reinforcing strips of adjacent support layers 2, and they form an included angle α in the horizontal projection direction. The isolation layer 3 is bonded to the support layer 2 with an adhesive, and the cover layer 4 is bonded to the isolation layer 3 with an adhesive.

[0027] The automotive interior panel of this embodiment can enhance the structural stability of the interior panel and improve its impact resistance; in addition, it can improve fire resistance and temperature resistance, and enhance safety.

Various modifications and alterations can be made without departing from the scope of the claims. The present invention includes all modifications and alterations within the scope of the claims.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
