[0030] like Figures 1-6 As shown, a multifunctional composite panel includes a housing 1, a PCB board 2 and a composite panel 3. The PCB board 2 is fixed inside the housing 1. A bracket 5 fixed inside the housing 1 is provided above the PCB board 2. A gap is left between the bracket 5 and the PCB board 2. The composite panel 3 is disposed on the bracket 5. The side of the composite panel 3 is fastened and fixed to the bracket 5.

[0031] The composite panel 3 includes a silicone layer 31, a PC layer 32, an ink layer 33, a plastic layer 34, and a touch sensing layer 35 arranged sequentially from the outside to the inside. The silicone layer 31 and the PC layer 32 are fixedly arranged by hot pressing or bonding. After the silicone layer 31 and the PC layer 32 are cut, they are formed into one piece by hot pressing or bonding in a mold, so that the two-layer composite structure combines the soft properties of silicone and the strength and light transmittance of PC material.

[0032] The outer surface of the silicone layer 31 is set with a leather texture structure. The outer surface of the silicone layer 31 can be set with a leather texture effect by embossing, which further enhances the feel of the composite panel 3.

[0033] The ink layer 33 includes transparent characters and opaque areas printed on the back of the PC layer 32 using transparent and opaque materials, for displaying the transparent characters that need to be raised so that the user can clearly identify the function of the touch area.

[0034] The plastic layer 34 is a light-transmitting plastic layer. The bracket 5 is provided with several light-transmitting holes 8 for the light rays on the PCB board 2 to pass through. The touch sensing layer 35 is made thinner at the corresponding light-transmitting holes 8 to facilitate the light to pass through the touch sensing layer 35, so that the light-transmitting characters in the ink layer 33 are illuminated by the light and make them more conspicuous.

[0035] The touch sensing layer 35 includes a touch sensor that is attached and fixed to the bottom of the plastic layer 34. The touch sensor is electrically connected to the PCB board 2 through the FPC socket 36 and the connector. The touch sensor is located at the bottom of the plastic layer 34 and contacts the top surface of the bracket 5. While detecting and transmitting touch information, the touch sensing layer 35 is supported by the bracket 5, which can reduce the probability of deformation and damage.

[0036] Furthermore, the composite panel 3 and the bracket 5 are provided with through holes 7 for placing the switch 6. One end of the switch 6 extends out of the top surface of the composite panel 3, and the other end is electrically connected to the PCB board 2 through a sensing device. The sensing device is existing technology. The switch 6 can be a press type or a swing type. The hole design on the composite panel 3 will not affect the function of the composite panel 3, nor will it affect the composite structure of the composite panel 3.

[0037] Specifically, the composite panel 3 combines a silicone layer 31 and a PC layer. It utilizes the soft properties of silicone and the strength and light transmittance of PC material to make the structure stable. At the same time, the silicone on the surface gives the composite panel 3 a skin-like tactile effect, making it more comfortable to touch when used as a car interior or other touch switch or button switch surface. Furthermore, the touch sensing layer 35 is electrically connected to the PCB board 2. When the user touches the composite panel 3, the position and intensity of the touch can be detected and feedback can be provided, enabling this composite structure to be applied to touch switches.
