Description

IME structure and process for surface of automotive interior trim
Technical Field
The invention relates to the field of automotive interior trim, in particular to an IME (in-mould etching) process for the surface of the automotive interior trim.
Background
At present, along with the improvement of living standard of people, people pay more and more attention to the texture and personality of automobile interior trim, and create a comfortable, beautiful and intelligent environment in the automobile becomes an important subject to be paid attention to by people. As is well known, in order to present the pleasing to the eye effect of intelligence, the structure of traditional automotive interior spare often is complicated, and occupation space is great and can't reach predetermined effect, and the restriction is more, and surface texture and interior trim atmosphere effect are single, can't merge perfectly with driver and passenger.
Disclosure of Invention
The invention aims to provide a novel IME process product with a simplified structure, light weight and diversified atmosphere effect for solving the problems of the conventional automotive interior trim part with a complex structure, heavy product and poor effect.
The technical scheme provided by the invention is as follows:
an IME process for the surface of an interior trim of a vehicle, comprising
1) Firstly, drawing a texture pattern required by the surface of the interior trim, and printing the texture pattern on a light-transmitting film through printing equipment;
2) combining and molding the light-transmitting matrix and the PC board;
3) fixing a flexible LED control circuit board and a light guide plate on a PC board together, wherein an LED lamp is arranged on the flexible LED control circuit board, and the light guide plate is arranged between the flexible LED control circuit board and the PC board;
4) through base material body and PC board injection moulding, with flexible LED control circuit and light guide plate cladding in the PC board.
The utility model provides an interior trim surface IME structure for vehicle, includes printing opacity diaphragm, PC board, light guide plate, flexible LED control circuit board, LED lamp and substrate body, the printing has the texture pattern on the printing opacity diaphragm, and printing opacity diaphragm and PC board compound mould, flexible LED control circuit board and light guide plate are fixed together on the PC board, are provided with the LED lamp on the flexible LED control circuit board, and the light guide plate setting is between flexible LED control circuit board and PC board, and substrate body and PC board injection moulding are with flexible LED control circuit and light guide plate cladding in the PC board.
Compared with the prior art, the intelligent surface membrane, the flexible circuit board, the light guide plate and the LED light source are integrated, so that the space is saved, meanwhile, the interaction between a driver, passengers and an automobile can be enhanced by perfectly combining graceful and rhythmic texture lines, an intelligent surface and an internal light environment, the space in the automobile is activated, a unique atmosphere of science and technology, romance or luxury is created, and the interior decoration of the automobile is more three-dimensional.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention is described in further detail below with reference to the attached drawings.
Referring to FIG. 1, an IME (In-Mold Electronics) process for the surface of a vehicle interior trim includes
1) The required texture pattern on the surface of the automotive interior is drawn by software in the early stage, the required texture effect is printed on the light-transmitting diaphragm 1 through printing equipment, and finally the light-transmitting diaphragm meeting the requirements of the automotive industry is manufactured through the combination of subsequent processes. After the diaphragm is manufactured, the formed diaphragm meeting the surface requirement of the part is formed by the diaphragm forming equipment
2) Injection molding, combining and molding the light-transmitting matrix 1 and the PC board 2; the PC board is formed by plastic, so that the surface defects of parts can be effectively controlled, and the thickness of the whole structural part can be controlled;
3) the flexible LED control circuit board 4 and the light guide plate 3 are fixed on the PC board 2 together, the LED lamp 6 is arranged on the flexible LED control circuit board, and the light guide plate 3 is arranged between the flexible LED control circuit board 4 and the PC board 2. The PC board is used as a bonding agent to be filled between the light-transmitting film and the small assembly of the flexible LED control circuit board. Different thickness sizes are formed through the forming equipment, and the surface defects of parts and the thickness of the whole structural part are effectively controlled. The light guide plate 3 simulates the light emitting effect and range through early software, designs the layout range of light guide points through software, and finally manufactures the required light guide plate through forming equipment. The light guide plate is quickly filled with the light-transmitting membrane area under the drive of LED light through a specific forming process, so that the light-emitting area and the uniform brightness are fully ensured, and the required surface light effect is achieved. The flexible LED control circuit board 4 uses software to draw a flexible circuit board drawing in the early stage, and selects a flexible circuit board made of a conductive material for matching with the thickness requirement. The driving is performed using a direct current power supply. And carrying out light control through the IO signal, giving different addresses to all RGB, enabling different addresses to represent RGB at different positions, and achieving the effect of light control through address control. The light conversion effect is changed by the RGB color matching table. The LED lamp can realize three primary colors conversion and single color effect as an embedded lamp source.
4) The flexible LED control circuit 4 and the light guide plate 3 are coated in the PC board 2 by injection molding of the base material body 7 and the PC board 2. The flexible LED control circuit 4 is provided with a plug 5, and the control circuit is connected with the control element in the vehicle through the plug 5, so that the LED lamp is controlled.
The injection molding substrate body 7 effectively combines the light-transmitting diaphragm, the PC board, the light guide plate, the flexible LED control circuit, the LED lamp and the plug together, and finally diversified novel IME process products are completed, so that the interior decoration effect of the whole vehicle is achieved.
