[0016] Example 1

[0017] like Figure 1-2 As shown, the present invention proposes an IME structure for automotive interior surfaces, including a film 1. An electronic component 8 is disposed on the inner side of the film 1. A flexible circuit 9 connected to the electronic component 8 is printed on the lower surface of the film 1. A light-transmitting resin layer 4 is adhered to the upper surface of the film 1. A substrate body 3, injection-molded with the film 1 and wrapped around the bottom of the film 1, is disposed below the film 1. During use, the substrate body 3 connects with the light-transmitting resin layer 4, forming a unified structure to improve protective performance. The electronic component 8 includes basic circuit components (existing technology, not described in detail here) and LED beads. During use, the electronic component 8, in conjunction with the flexible circuit 9, controls the components within the vehicle and illuminates the light-transmitting resin layer 4.

[0018] In an optional embodiment, the diaphragm 1 is made of PC material, so that the flexible circuit 9 can be fabricated on the surface of the diaphragm 1 by screen printing technology, and the diaphragm 1 and the flexible circuit 9 are arranged integrally.

[0019] In an optional embodiment, the upper surface of the light-transmitting resin layer 4 is coated with a light-shielding coating 5, wherein the coating is applied according to the use of the button, so that the light emitted by the electronic component 8 illuminates only the button area through the light-shielding coating 5, avoiding the light from affecting the clarity of the button.

[0020] In an optional embodiment, a decorative layer 6 is provided above the light-transmitting resin layer 4, covering the outside of the light-shielding coating 5. The surface of the decorative layer 6 has decorative and usage patterns to improve aesthetics and allow the user to clearly see the function buttons. In use, the decorative layer 6 can also be directly pasted onto the upper surface of the diaphragm 1.

[0021] In an optional embodiment, the flexible circuit 9 has a connection port 7 on its side, which extends to the outside of the diaphragm 1. The connection port 7 is used to connect the flexible circuit 9 to the vehicle circuitry during use, so that the electronic components 8 disposed on the flexible circuit 9 can control the electronic components in the vehicle.

[0022] In an optional embodiment, a thin film 2 is provided on the lower surface of the diaphragm 1 and above the substrate body 3 for encapsulating the flexible circuit 9 and electronic components 8 inside the diaphragm 1 in use. The thin film 2 is made of the same material as the diaphragm 1 and is arranged to be adapted to the diaphragm 1. It is used to connect with the diaphragm 1 in use to encapsulate the flexible circuit 9 in the diaphragm 1 and prevent the flexible circuit 9 from contacting the substrate body 3.

[0023] In this invention, the flexible circuit 9 is prepared on the diaphragm 1 using screen printing technology, so that the diaphragm 1 and the flexible circuit 9 are integrated into one structure. The diaphragm 1 is cut into a suitable shape, and the electronic component 8 and the flexible circuit 9 are encapsulated in the diaphragm 1 by the thin film 2. The connection port 7 is placed on one side of the diaphragm 1. At the same time, the light-transmitting resin layer 4 is pasted on the upper surface of the diaphragm 1, and the substrate body 3 is connected to the diaphragm 1 from below by injection molding. The light-transmitting resin layer 4 and the substrate body 3 protect the flexible circuit 9 and prevent the substrate body 3 from affecting the flexible circuit 9.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
