Abstract
The utility model relates to an automobile ceiling decorative sheet with the function of absorbing sound and lowering noise, comprising a substrate, wedge absorbers and a decorative layer. The wedge absorbers are uniformly distributed on the substrate at intervals, and the decorative layer covers the surfaces of the wedge absorbers. In the utility model, the wedge absorbers are additionally arranged on a traditional automobile ceiling inner decorative sheet and are utilized to cover the automobile ceiling, and sound absorbing material is added in the wedge absorbers, thereby the sound absorbing effect is improved, the noise inside the automobile is reduced, and the comfort of the automobile is improved.
Description
Technical field
The utility model relates to a kind of car trim, is specifically related to a kind of roof of the vehicle trim board with sqouynd absorption lowering noise function.
Background technology
Raising along with people's living standard, people are also more and more higher to the requirement of the traveling comfort of automobile, and influence the noise problem that just comprises in the factor of car comfort in the car, and for high-end vehicles, the task of reducing internal car noise is then more arduous, therefore the designer begins to have in mind on automotive interior material, in the hope of realizing the purpose of sqouynd absorption lowering noise in the aesthetic property in guaranteeing car.
The day for announcing is that June 27 calendar year 2001, notification number are the interior ceiling decoration plate of automobile of CN2436362, it adheres to substrate by non-woven mat forms, wherein, and on the said substrate, at the PP(polypropylene) sheet material is processed into cellularly, and said non-woven mat is the stamp non-woven mat.This utility model moderate cost, outer tube is attractive in appearance, Applicable scope is wide, and it does not possess sound absorption function, can not reduce the noise of vehicle interior, though played the traveling comfort that the effect of beautifying but can not improve vehicle.
The utility model content
The utility model provides a kind of roof of the vehicle trim board that possesses the sqouynd absorption lowering noise function, realizes sqouynd absorption lowering noise when the assurance vehicle is attractive in appearance, improves the traveling comfort of vehicle.
At the problems referred to above, the technical scheme that the utility model is taked is:
A kind of roof of the vehicle trim board comprises substrate, wedge absorber and decorative layer, and the wedge absorber each interval is evenly distributed on the substrate, and decorative layer covers the wedge absorber surface.The decoration plate that uses mostly is materials such as board fiber board or polypropylene now, and this material is solid firm, the setting of favourable wedge absorber thereon.Wedge absorber covers whole roof of the vehicle, and the sacrifice area is big, and assimilation effect is obvious, effectively noise insulation.The decorative layer that covers the wedge surface plays effect attractive in appearance, improves the aesthetics of vehicle interior.
As optimization, constitute a hollow structure between wedge and substrate, be filled with sound-absorbing porous material in the structure of this hollow.The sound-absorbing porous material of being filled in wedge further strengthens the acoustically effective of wedge absorber, improves anti-acoustic capability.
As optimization, sound-absorbing porous material comprises glass fiber blanket, glass fibre, slackness wool, foamed plastic, and these materials are common in the market sound-absorbing material, and is not only cheap, and acoustically effective is remarkable.
As optimization, constitute a hollow structure between wedge and substrate, be provided with air layer in the structure of this hollow.Filling sucting sound material can not play cooresponding acoustically effective by Wedge structure also, though effect decreases, manufacture craft is simple, and cost is low.
Compared with prior art, advantage of the present utility model is: by increase wedge absorber on orthodox car ceiling trim panel, utilize wedge absorber to cover roof of the vehicle, and in wedge, add sound-absorbing material, improve acoustically effective, thereby reduce internal car noise, improve the traveling comfort of vehicle.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the cutaway view of a kind of embodiment of the present utility model and the structural representation of wedge absorber;
Fig. 3 is the cutaway view of another kind of embodiment of the present utility model and the structural representation of wedge absorber.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1 and Figure 2, the substrate of roof of the vehicle trim board described in the utility model 1 is made by polypropylene material, is provided with wedge absorber 2 on substrate 1 evenly and at intervals, on wedge absorber 2 with the made decorative layer 3 of one deck chintz.
Wherein wedge absorber 2 as shown in Figure 2, it is the conical wedge of a hollow, constitutes the structure of a hollow between its skeleton and substrate, adorn with foamed materials 4 at this hollow structure, foamed materials 4 is common material common on the market, and cheap, acoustically effective is remarkable.
External noise penetrates ceiling when entering in the vehicle, sound wave is 2 tip from substrate 1 to wedge absorber, acoustic impedance is the impedance that progressively carries out the transition to foamed materials 4 from the characteristic impedance of air, thereby realized good impedance match, incident acoustic energy is absorbed efficiently, thereby realize the purpose of sqouynd absorption lowering noise.
Embodiment 2:
As Fig. 1, shown in Figure 3, the substrate of roof of the vehicle trim board described in the utility model 1 is made by board fiber board, is provided with wedge absorber 2 on substrate 1 evenly and at intervals, on wedge absorber 2 with the made decorative layer 3 of one deck chintz.
Wherein wedge absorber 2 as shown in Figure 3, it is the conical wedge of a hollow, constitutes the structure of a hollow between its skeleton and substrate, this hollow structure is not filled any material, is air layer 5.External noise penetrates ceiling when entering in the vehicle, and sound wave is 2 tip from substrate 1 to wedge absorber, and sound wave vibrates in the air layer 5 of conical wedge, makes that incident acoustic energy is absorbed efficiently, thereby realizes the purpose of sqouynd absorption lowering noise.This implementation method advantage is simple in structure, and input cost is low.
Claims (3)
1. a roof of the vehicle trim board is characterized in that, it comprises substrate, wedge absorber and decorative layer, and described wedge absorber each interval is evenly distributed on the substrate, and described decorative layer covers the wedge absorber surface.
2. a kind of roof of the vehicle trim board according to claim 1 is characterized in that, constitutes a hollow structure between described wedge and substrate, is filled with sound-absorbing porous material in the structure of this hollow.
3. a kind of roof of the vehicle trim board according to claim 1 is characterized in that, constitutes a hollow structure between described wedge and substrate, is provided with air layer in the structure of this hollow.
