Four nuts 4 are symmetrically arranged at the upper end of the circuit board body 1. The lower end of each nut 4 is connected to a nut column 3. The nut column 3 passes through the circuit board body 1 and is arranged at the lower end of the circuit board body 1. A threaded hole 301 is provided inside the nut column 3.

[0021] Through this design, the setting of the nut column 3 provides a stable connection point. When the circuit board body 1 is installed inside the vehicle, the circuit board can be firmly fixed in place through the threaded hole 301 of the nut column 3. The nut 4 realizes the fixation of the nut column 3, which not only improves the convenience of installation, but also increases the stability of the circuit board during use, reducing the impact on the display screen caused by the bumps during vehicle driving.

[0023] Through this design, the display driving module 5 can effectively drive the LED display screen to work, and the setting of the radiator 6 ensures that the heat generated by the display driving module 5 during operation can be dissipated in time. The design of the arc-shaped fins 601 increases the heat dissipation area of the radiator 6, thereby improving the heat dissipation efficiency, avoiding the performance degradation or damage of the display driving module 5 caused by overheating, and extending the service life of the device.
