Further, the upper surface on the surface layer is additionally provided with for anti-skidding non-slip texture.The design is to improve The comfort level of upholstery, also, child is effectively avoided not help the unexpected scratch of steady appearance because surface is smooth in the car.

Further, the non-slip texture is suppressed using after TPO material heating.The processing method effect is good, carries The physical life of high TPO material.

Further, the non-slip texture is in contoured shape or net-shaped.

Further, the installation end face of the base is smooth flat.This is designed with the installation conducive to composite structure, Protect automotive interior parts.

Further, the thickness on the surface layer is not less than 0.5mm.The design method is ensureing not according to the demand of automobile It can ensure the comfortable feel degree of interior trim simultaneously in the case of reducing inner space of vehicle, while be capable of providing preferable buffering effect Fruit.

Further, the thickness on the surface layer is 0.5mm-2mm.The effect of the thickness is in the holding of the elastic force of TPO material On be that there is better effect, good buffer effect.

Further, the thickness of the base is not less than 1mm.The design is to ensure the intensity of backing material plate, while also need Ensure the buffering effect of backing material plate, so as to reach security performance and comfort level more preferably state.

Further, the thickness of the base is 2mm-3mm.The program is conducive to the design of automotive interior trim, certain Cushion effect in the case of, which can play the role of protection, and safety is then popped up in the power that can be carried more than the buffering Air bag.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：The one of the utility model Kind TPO composite structures effectively solve the problems, such as domestic upholstery soft material at present, simple in structure, elastic effect More preferably, and interior comfort level can be promoted effectively, increased security performance guarantee, reduced production cost.
