[0022] The bottom wall of the rocker 12 is provided with four panel contacts 13, which correspond to the positions of the circuit board contacts 5. The panel contacts 13 are located above the circuit board contacts 5. When the function area of ​​the button panel 6 is pressed and deformed, it causes the rocker 12 to tilt, so that the panel contacts 13 of the rocker 12 contact the circuit board contacts 5 to trigger the corresponding function.

[0023] The surface of the button panel 6 function area is made of a one-piece soft material (such as silicone or ABS engineering plastic). The bottom wall of the rocker arm 12 is provided with four panel contacts 13. The panel contacts 13 correspond to the positions of the circuit board contacts 5, and the panel contacts 13 are located above the circuit board contacts 5, forming the core transmission structure for button triggering.

[0024] A rubber dustproof sheet 15 is fixedly sleeved on the periphery of the button panel 6. A frame plate 16 is connected to the bottom side wall of the rubber dustproof sheet 15. A frame groove 17 is opened on the end wall of the panel button box 2. The frame plate 16 and the frame groove 17 are inserted into each other.

[0025] A rubber dustproof sheet 15 is fixedly fitted onto the perimeter of the button panel 6. A frame plate 16 is connected to the bottom side of the rubber dustproof sheet 15. A frame groove 17 is formed on the end wall of the button box 2, and the frame plate 16 is inserted into the frame groove 17. Through the sealing effect of the rubber dustproof sheet 15, dust, water stains and other impurities can be effectively prevented from entering the interior of the button box 2, avoiding impurities adhering to the circuit board contacts 5 and affecting signal transmission, thus improving the service life of the buttons.

At this time, the panel contact 13 on the bottom wall of the rocker arm 12 is separated from the circuit board contact 5 at the bottom of the panel groove 4, the button is not triggered, and the integrated wiring harness is in standby transmission state. When the driver presses the corresponding function area of ​​the button panel 6, the button panel 6 undergoes local deformation under the pressing force. This deformation force is transmitted to the rocker arm 12 through the elastic lever 10. Since the rocker arm 12 is positioned against the elastic lever 10 via the locking posts 14 at the four corners, the deformation of the button panel 6 will cause the rocker arm 12 to tilt in the corresponding pressing direction. As the rocker arm 12 tilts, the panel contact 13 at the corresponding position on its bottom wall moves downward until it contacts the circuit board contact 5 at the bottom of the panel groove 4. After the panel contact 13 contacts the circuit board contact 5, an electrical signal path is formed. The button trigger signal is transmitted to the vehicle control system through the integrated wiring harness connected to the panel button box 2. After receiving the signal, the control system executes the corresponding function command (such as adjusting the volume, switching multimedia, controlling cruise, etc.). In addition, the rubber dustproof sheet 15, through the insertion and cooperation of the frame plate 16 and the frame groove 17, always seals the connection between the panel button box 2 and the button panel 6, preventing impurities from entering the interior and ensuring the stable operation of each transmission structure and contact.
