Abstract
The invention discloses a kind of cover plate of spare tire of automobile, cover board body including lamination layer structure, described cover board body includes needled fabric, two-layer PP wood flour board and non-woven fabrics the most successively, forming several cavitys between described two-layer PP wood flour board, described needled fabric and non-woven fabrics are bonded in the surface of PP wood flour board respectively.This spare tire cover plate light weight, bearing capacity are strong, sound insulation and noise reduction is effective.
Description
Technical field
The present invention relates to automobile trunk inner part, be specially a kind of cover plate of spare tire of automobile.
Background technology
Spare tire cover plate is a kind of for hiding, isolate spare tyre cabin, it is achieved automobile trunk is smooth and the conforming decoration of layout, sound insulation bearing part, plays body-finishing, the carrying effect such as weight, sound insulation and noise reduction.Existing cover plate of spare tire of automobile typically uses hardboard gluing composite carpet stamping-out molding or hot-forming with PP wood flour board direct combination fabric.
CN202053585U discloses a kind of cover plate of spare tire of automobile, and as shown in Figure 6, it is made up of carpet 201, upper PP glass-fiber-plate 202, cellular board 203, lower PP glass-fiber-plate 204 and non-woven fabrics 205 the most successively, each layer viscous by bonding agent 206 and.Owing to this spare tire cover plate is formed by above-mentioned multilamellar solid material compound sticking, therefore there is the defects such as weight is big, yielding, sound insulation and noise reduction is poor, bearing capacity is limited in this spare tire cover plate, along with being continually changing and ripe of the development of automotive material technology and consumer's theory, existing cover plate of spare tire of automobile can not meet the requirement to aspects such as durability, safety, comfortableness, the feature of environmental protection and the economy of automobile of auto vendor and consumer.
Summary of the invention
It is an object of the invention to provide a kind of cover plate of spare tire of automobile, its light weight, bearing capacity are strong, sound insulation and noise reduction is effective.
Cover plate of spare tire of automobile of the present invention, cover board body including lamination layer structure, described cover board body includes needled fabric, two-layer PP wood flour board and non-woven fabrics the most successively, forming several cavitys between described two-layer PP wood flour board, described needled fabric and non-woven fabrics are bonded in the surface of PP wood flour board respectively.
Further, the PP wood flour board of described internal layer is additionally provided with the convex tendon of multiple evagination.
Further, described cover board body is divided into the forward and backward two parts that can relatively turn down, and flexibly connects between described forward and backward two parts.
Further, described needled fabric and non-woven fabrics are bonding with described PP wood flour board by PP film.
Further, the front end at described cover board body is provided with latch structure.
Further, at the appearance topcoating dehydrated glue of described needled fabric.
Spare tire cover plate of the present invention by arranging cavity in cover board body, can alleviate the weight of spare tire cover plate significantly, and increases the intensity of spare tire cover plate, promotes spare tire cover plate sound-insulating and heat-insulating ability simultaneously.Therefore, spare tire cover plate of the present invention have that lightweight, bearing capacity is strong, shock resistance and the advantage of energy-absorbing sound-insulating and heat-insulating.

Detailed description of the invention
The present invention is further elaborated with embodiment below in conjunction with the accompanying drawings:
Cover plate of spare tire of automobile as Figure 1-5, cover board body 1 including lamination layer structure, described cover board body is made up of needled fabric 101, two-layer PP wood flour board 102 and non-woven fabrics 103 the most successively, described non-woven fabrics is PET non-woven fabrics, described needled fabric 101 and non-woven fabrics 103 are bonded in the surface of PP wood flour board respectively by PP film 106, and described PP film is made up of polypropylene material, and the feature of environmental protection is good, after hot-forming, bond the most firm.
Seeing Fig. 2,102 the hollow blowing compression moldings of described two-layer PP wood flour board have several cavitys 104, and the purpose designing cavity in cover board body is: one, can significantly alleviate the weight of spare tire cover plate；Two, spare tire cover plate intensity is strengthened；Three, spare tire cover plate noise reduction heat-insulating capability is improved.
See Fig. 3, the PP wood flour board 102 of described internal layer is additionally provided with the cross convex tendon 105 of multiple evagination, for contacting with spare tyre surface, support spare tire cover plate, improve spare tire cover plate bearing capacity.
Described cover board body 1 is divided into the forward and backward two parts 11,12 that can relatively turn down, as shown in Figure 4, when mould heat pressure molding, two-layer PP wood flour board 102 cuts off at the demarcation line 13 of described forward and backward two parts 11,12, needled fabric 101 is connected with non-woven fabrics 103, flexibly connect between two parts so that the rear section 12 of cover board body can turn down opens, and conveniently picks and places spare tyre and driver's tool etc..
Seeing Fig. 5, be provided with two latch structures 14 in the front end of described cover board body, during assembling, two described latch structures 14 are inserted in the bootspace box body opening of front end, can limit spare tire cover plate and move, play fixation.
For improving cover board body surface smoothness, the outer surface at described needled fabric 101 scribbles dehydrated glue.
It is below the model parameter of above-mentioned each parts: needled fabric density: 300g/m2~600 g/m2, PET non-woven fabrics density: 100g/m2~200 g/m2, monolayer PP wood flour board thickness is 2mm, PP film density: 80g/m2~100g/m2, dehydrated glue density: 100g/m2~200g/m2。
