[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] In the present application, it is necessary to explain that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0023] A vehicle display screen control box structure, as shown in Figure 2 - Figure 5 The shell 1 is provided with a circuit board connecting column 2 inside the shell, a lower circuit board 3 is installed at the lower section of the circuit board connecting column, and an upper circuit board 4 is installed at the upper section of the circuit board connecting column. One end of the upper circuit board is provided with a chip and a chip heat sink 5, and the other end is provided with a first antenna 6. The upper circuit board on both sides of the chip heat sink is respectively provided with a second antenna 7 and a third antenna 8. The shell at both ends of the upper circuit board is provided with a signal through hole 9.

Two, three, or four circuit board connecting posts can be provided. Each connecting post can be installed onto the lower cover via a threaded connection at its bottom. The lower circuit board 3 is inserted through a through-hole and fixed to the lower section of the connecting post. The upper circuit board is inserted through a through-hole and fixed to the upper section of the connecting post. A gap is provided between the lower and upper circuit boards to increase airflow and improve heat dissipation. The lower and upper circuit boards are electrically connected via pins or wires. After the upper and lower circuit boards are installed, the upper and lower covers are closed and secured with screws or studs, installing the upper and lower circuit boards inside the control box. Both the lower and upper covers are made of plastic, which reduces antenna signal shielding and improves the antenna's signal transmission and reception capabilities.
