Problems solved by technology

Although the use of adhesive bonding has solved the problem of connecting the fixed buckle and the skeleton substrate to a certain extent, there are still many shortcomings: on the one hand, the price of this type of adhesive is very expensive, which leads to the production cost of interior parts. On the other hand, the bonding strength is only about 50N, which is still not ideal, especially for metal buckles, the bonding effect is not ideal

Embodiment 1

[0028] As shown in Fig. 1 to Fig. 8, it is a preferred embodiment of the present invention. As shown in Figures 1 to 8, the automotive interior parts in this embodiment have a skeleton base material 1 and a fixing buckle 2 whose surface layer is non-woven fabric, and the fixing buckle 2 includes a metal buckle 3 with a bottom plate 31 and a fixing buckle 2. The plastic buckle 4 is connected to the metal buckle 3 , and the bottom plate 31 of the metal buckle 3 is provided with counterbore-like holes 32 with a large upper part and a smaller lower part. Between the skeleton base material 1 and the bottom plate 31 of the metal buckle 3 is provided a wood powder board 5 containing polypropylene which is slightly larger than the bottom plate 31 of the metal buckle. The composite of the skeleton base material 1 and the wood powder board 5 is formed by pressing in a softened state, and the wood powder board 5 is pressed in the softened state to fill up the holes on the metal buckle bo...

Embodiment 2

[0036] As shown in Figure 9, and referring to Figures 1 to 8, the automotive interior part of this embodiment has a skeleton base material 1 with a carpet surface and a fixed buckle 2, and the fixed buckle 2 includes a metal buckle with a bottom plate 31 3 and the plastic buckle 4 fixed on the metal buckle 3 , the bottom plate 31 of the metal buckle 3 is provided with a hole 33 . A polypropylene plate 6 having the same size as the bottom plate 31 of the metal buckle is disposed between the skeleton base material 1 and the bottom plate 31 of the metal buckle 3 . The composite of the skeleton base material 1 and the polypropylene plate 6 is formed by pressing in a softened state, and the part of the polypropylene plate 6 enters the hole 33 due to being pressed in the softened state and is buckled at the mouth of the hole 33. The outer edge of the part, and thus the skeleton base material 1, the polypropylene plate 6 and the metal buckle 3 are fixed as a whole.

Abstract

The invention discloses a vehicle inner ornament and the manufacturing method. It is made up of frame base material and fixed a buckle that includes bottom board. The feature is that the frame base material compounding or polypropylene included woodflour board including polypropylene board, and the bottom board of fixed buckle is connected on the polypropylene board or the woodflour board. The method includes the following steps: softening frame base material and polypropylene board or woodflour board, putting fixed buckle into mold and locating the polypropylene board or woodflour board and base material into mold, and ensuring the polypropylene board and woodflour board is located between bottom board and frame base material; taking pressure forming. The bond strength between buckle and frame base material could reach 420N, and it is low cost. It is convenient to produce and has high efficiency.

Description

technical field [0001] The invention relates to an automotive interior trim and a manufacturing method thereof. Background technique [0002] Automotive interior parts are accessories installed on the top of the car, inside the door, and in the cockpit. They are used to decorate the interior of the car to improve people's comfort when riding in the car. They usually have functions such as sound insulation, shock resistance, and decoration. [0003] The structure of the automotive interior usually includes a skeleton substrate and a fixing buckle arranged on the skeleton substrate for connecting the vehicle body. The skeleton substrate is generally a multi-layer structure, and its surface layer is usually non-woven fabric, carpet, felt, etc. According to the requirements of the tooling, the skeleton substrate usually needs to be connected with fixing buckles, and finally connected to the body sheet metal parts through the fixing buckles. There are many kinds of fixing buckl...
