[0026] Furthermore, the buffering airflow heat sink includes a vertical movable groove 8 opened on the inner wall of the installation frame 3, and the side wall of the pneumatic bearing seat 4 is fixedly connected with a bearing buffer block 9 located in the vertical movable groove 8, and the bottom of the bearing buffer block 9 is connected to the inner wall of the vertical movable groove 8 through a buffer spring.

[0027] Furthermore, a pneumatic piston opening is opened inside the installation frame 3, and the load-bearing buffer block 9 is connected to the pneumatic piston disk 10 located in the vertical movable groove 8 through an air guide column. A plurality of heat dissipation holes 11 are evenly opened on the inner side wall of the installation groove 5, and the heat dissipation holes 11 are connected to the pneumatic piston opening through a conveying channel.

[0028] A further benefit of adopting the above is that during the driving of the car, the pneumatic bearing seat 4 performs buffering and shock absorption through the buffer spring to ensure that the chip mainboard 1 arranged thereon is protected and meets the performance requirements for vehicle-mounted use. The bearing buffer block 9 connected by the buffer spring will drive the pneumatic piston disk 10 connected thereto through the air guide column to move in the pneumatic piston mouth during the buffering vibration process. During the movement, the pneumatic piston disk 10 will squeeze the gas in the pneumatic piston mouth, so that air flow is generated at the heat dissipation hole 11, thereby achieving effective heat dissipation of the chip mainboard 1 thereon.

[0029] The pneumatic bearing seat 4 is provided with a mounting groove 5 for mounting the chip mainboard 1, and the pneumatic bearing seat 4 is provided with a limiting member for fixing the chip mainboard 1;

[0030] Furthermore, the limiting component includes a limiting connection port opened on the side wall of the installation frame 3, and an L-shaped limiting block 12 is slidably provided on the inner wall of the limiting connection port, and the L-shaped limiting block 12 is connected to the side wall of the installation frame 3 through a connecting spring; during installation, multiple L-shaped limiting blocks 12 are moved outward, and after the chip main board 1 is installed, under the resetting effect of the connecting spring, the L-shaped limiting block 12 is moved inward, and the chip main board 1 is limited in the installation groove 5.

[0031] A combined mounting seat is arranged above the pneumatic bearing seat 4, and the combined mounting seat is connected to an adapter through a stabilizing assembly. Further, the adapter includes an adapter seat 13, an adapter groove is provided on the adapter seat 13, and an adapter bar 15 is connected to the adapter seat 13 through a fastening clamp 14. A terminal 16 is arranged at the end of the adapter bar 15, and a pin pressing opening is provided on the adapter bar 15. A pin terminal strip 17 adapted to the pin pressing opening is arranged on the adapter groove;

[0032] It should be noted that the pins of the flexible circuit board 2 are adapted to the pin terminal strip 17. During installation, it is only necessary to insert the pins of the flexible circuit board 2 into the pin terminal strip 17, and then install the adapter strip 15 and the adapter seat 13 by fastening the clamps 14, and fasten and connect the pins of the flexible circuit board 2 by the pin pressing.

[0033] Furthermore, the combined mounting seat is composed of two relatively arranged combined half covers 18, and the combined half cover 18 at the bottom is connected to the mounting frame 3 through a corner connecting block 19;

A heat dissipation port is provided inside the heat sink 6, and a heat dissipation fan 7 is provided on the inner wall of the heat dissipation port. The heat dissipation port is located directly above the chip main board 1, and can effectively realize the effective impact heat dissipation of various electrical components on the chip main board 1. Heat dissipation rectangular ports are provided on both sides of the mounting frame 3 for realizing the circulation of airflow, so as to realize the effect of flow heat dissipation of the chip main board 1 through gas.

[0037] The outer wall of the heat sink 6 is provided with a torsion resistance member for guiding the flexible circuit board 2, and the torsion resistance member includes a rotating inner shaft 23 fixedly provided on the side wall of the heat sink 6, the rotating inner shaft 23 is connected to a side support rod 24 through a torsion spring, and the side support rod 24 is connected to a resistance collar 25 through a rotating shaft;

Among the relatively arranged torsion resistance members, the torsion springs are relatively arranged, that is, the torsion spring located at the top applies a force to the side support rod 24 to drive the resistance ring 25 to rotate upward, and the torsion spring located at the bottom applies a force to the side support rod 24 to drive the resistance ring 25 to rotate downward.
