Abstract

The utility model discloses a photocatalyst interior trim panel for a vehicle, which sequentially comprises a first decorative panel, a buffer layer and a second decorative panel from bottom to top, wherein a light guide plate is arranged between the second decorative panel and the buffer layer, and a light source is arranged on one side of the light guide plate; a plurality of through holes are formed in the second decorative plate, the lower surface of the second decorative plate is sprayed with a photocatalyst coating, and the upper surface of the second decorative plate is provided with a porous film layer. When the automobile air purifier is used, air in the automobile sequentially passes through the porous film layer and the through holes in the second decorative plate and then contacts with the photocatalyst layer. Meanwhile, the light guide plate uniformly emits light of the light source to the photocatalyst layer, after the photocatalyst on the photocatalyst layer absorbs light energy, oxygen in the air is converted into strong oxidation active groups, and the strong oxidation active groups can degrade toxic and harmful gases in the air and kill bacteria, so that the aim of purifying the air in the vehicle is fulfilled.

Description

Plaque in automobile-used photocatalyst

Technical Field

The utility model belongs to the technical field of automobile accessories, and particularly relates to a photocatalyst interior trimming panel for a vehicle.

Background

With the popularization of automobiles, the proportion of automobiles selected as vehicles is higher and higher when people go out. When a vehicle runs, the windows of the vehicle are closed most of the time, so that the environment in the vehicle is closed and is not ventilated, smoke, sweat, dust and the like in the vehicle are gathered on the surface of the automotive interior trim panel, peculiar smell is easily generated, and bacteria and viruses are bred for a long time. In addition, in the production process of automobiles, some plastic, adhesive, rubber and other chemical materials are usually used, which can continuously volatilize benzene series, aldehyde pollutants and the like, are in a closed automobile for a long time, are easy to cause symptoms such as dizziness, headache, somnolence, chest distress and the like, can also cause discomfort of a digestive system, generate inappetence, nausea and the like, and can seriously damage the liver and a hematopoietic system.

At present, people often wipe the automotive interior panel regularly to reach the effect of removing dust, but only wipe and hardly get rid of bacterium, virus on the interior panel, and can't avoid the poisonous and harmful gas in the car.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects of the prior art and provides a photocatalyst interior trimming panel for a vehicle.

The utility model is implemented by the following technical scheme:

a photocatalyst interior trim panel for a vehicle sequentially comprises a first decorative panel 1, a buffer layer 2 and a second decorative panel 3 from bottom to top, wherein a light guide plate 4 is arranged between the second decorative panel 3 and the buffer layer 2, and a light source 5 is arranged on one side of the light guide plate 4; the second plaque 3 on seted up a plurality of through-holes 6, the lower surface spraying of second plaque 3 has photocatalyst coating 7, the upper surface is provided with porous rete 8.

When the automobile air purifier is used, air in an automobile sequentially passes through the porous membrane layer 8 and the through holes 6 in the second decorative plate 3 and then contacts with the photocatalyst layer. Meanwhile, the light of the light source 5 is uniformly emitted to the photocatalyst layer from the upper surface of the light guide plate 4 by the light guide plate 4, and after the photocatalyst on the photocatalyst layer absorbs light energy, oxygen in the air is converted into strong oxidation active groups, and the strong oxidation active groups can degrade toxic and harmful gases in the air and kill bacteria, so that the aim of purifying the air in the vehicle is fulfilled. When a car accident happens, the first decorative plate 1 and the second decorative plate 3 play a supporting role, so that the structural strength of the interior decorative plate can be improved, and the collision supporting capacity can be improved; the buffer layer 2 can play a certain buffering role, and damage to a human body caused by collision is reduced. The photocatalyst layer is arranged on the lower surface of the second decorative plate 3, and the through hole 6 on the second decorative plate 3 is coated by the porous film layer 8, so that the photocatalyst layer can be prevented from being directly exposed to the outside to cause scratch and drop.

Optionally, the light source 5 is an LED lamp.

Optionally, the porous membrane layer 8 is a knitted fabric layer or a dermis layer. The knitted fabric and the real leather have certain air permeability, and air in the vehicle can be contacted with the photocatalyst layer through the knitted fabric layer or the real leather layer.

Optionally, the buffer layer 2 is a sponge layer. The sponge layer not only has a buffering effect, but also has the functions of sound insulation and noise reduction.

Compared with the prior art, the utility model has the following beneficial effects:

1. according to the utility model, the photocatalyst layer is arranged in the inner decorative plate, and after the photocatalyst on the photocatalyst layer absorbs light energy, oxygen in the air is converted into strong oxidation active groups, and the strong oxidation active groups can degrade toxic and harmful gases in the air and kill bacteria, so that the aim of purifying the air in the vehicle is achieved;

2. the light guide plate is arranged, so that light of the light source can be uniformly irradiated on the photocatalyst coating, and the photocatalyst on the photocatalyst coating can be contacted with the light to the maximum extent, so that the photocatalytic efficiency is improved, and the air purification effect is improved;

3. the photocatalyst layer is arranged on the lower surface of the second decorative plate, and the through hole on the second decorative plate is coated by the porous film layer, so that the photocatalyst layer can be prevented from being directly exposed to the outside to be scratched and fall off.
