Problems solved by technology
Since the spare tire cover is compositely bonded by the above-mentioned multi-layer solid materials, the spare tire cover has defects such as heavy weight, easy deformation, poor sound insulation and noise reduction, and limited bearing capacity. With the development of automobile material technology and the With the continuous change and maturity of consumer concepts, the existing automobile spare tire cover can no longer meet the requirements of automobile manufacturers and consumers on the durability, safety, comfort, environmental protection and economy of automobiles.

Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment the present invention will be further elaborated:
[0019] Such as Figure 1-5 The shown automobile spare tire cover includes a cover body 1 with a composite layer structure, and the cover body is sequentially composed of needle-punched fabric 101, two-layer PP wood powder board 102 and non-woven fabric 103 from outside to inside. The non-woven fabric is PET non-woven fabric, and the needle-punched fabric 101 and the non-woven fabric 103 are respectively bonded to the surface of the PP wood powder board through the PP film 106. The PP film is made of polypropylene material, which is environmentally friendly. Well, after thermoforming, the bond is very strong.
[0020] see figure 2 There are several cavities 104 in the hollow blow molding between the two layers of PP wood powder boards 102. The purpose of designing the cavities in the cover body is: 1. It can greatly reduce the weight of the spare tire cove...

Abstract
The invention discloses an automobile spare tire cover-plate which comprises a cover plate body with a composite layered structure. The cover plate body comprises, from outside to inside, a needling fabric, two layers of PP wood powder plates and a non-woven fabric. Several cavities are formed between the two layers of PP wood powder plates. The needling fabric and the non-woven fabric are respectively adhered to the surface of the PP wood powder plates. The spare tire cover-plate has advantages of light weight, high carrying capacity and good sound insulation and noise reduction effect.
Description
technical field [0001] The invention relates to an inner part of an automobile trunk, in particular to an automobile spare tire cover plate. Background technique [0002] The spare tire cover is a decorative and sound-proof bearing part used to cover and isolate the spare tire compartment to achieve a flat and consistent layout of the trunk of the car. It plays the role of car body decoration, carrying heavy objects, sound insulation and noise reduction. Existing automobile spare tire cover plate generally adopts hard fiberboard glued compound carpet blanking molding or direct composite material hot pressing molding with PP wood powder board. [0003] CN202053585U discloses a kind of automobile spare tire cover plate, as Figure 6 As shown, it consists of a carpet 201, an upper PP fiberglass board 202, a honeycomb board 203, a lower PP fiberglass board 204, and a non-woven fabric 205 from top to bottom, and each layer is bonded together by an adhesive 206. Since the spare t...
