Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a circuit board support structure for a brake power board, including a mounting base 5 and a circuit board assembly 8. Support brackets 7 are installed on the front and rear ends of the top of the mounting base 5. An upper fixing knob 11 is inserted into the top of the support bracket 7. A pressure block 16 is connected to the bottom of the upper fixing knob 11. A fixing seat 14 is installed on the top left side of the mounting base 5. A telescopic spring 15 is installed inside the fixing seat 14. A movable stop block 12 is connected to the top of the telescopic spring 15. A limit plate 9 is installed on the top right side of the mounting base 5.

[0024] The support bracket 7 is provided in four sets. The circuit board assembly 8 is inserted into the inner side of the support bracket 7 at the top of the mounting base 5. The upper fixing knob 11 is inserted into the top of the support bracket 7 and connected to the pressure block 16 inside the support bracket 7. The upper fixing knob 11 drives the pressure block 16 to contact the circuit board assembly 8 inside the support bracket 7. The circuit board assembly 8 is inserted into the inner side of the support bracket 7 and contacts the limiting plate 9 on the right side of the top of the mounting base 5. The movable stop 12 extends and retracts at the top of the fixed seat 14 through the telescopic spring 15. The fixed seat 14 is provided in two sets.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, by setting a support and fixing structure, the present invention is beneficial in that: when in use, the movable stop 12 is retracted inside the fixed base 14 by the telescopic spring 15, so that the circuit board assembly 8 on both sides is inserted into the four sets of support brackets 7 on the top of the mounting base 5, and one side of the circuit board assembly 8 contacts the limiting plate 9 on the right side of the top of the mounting base 5. Then, the upper fixing knob 11 on the top of the support bracket 7 is rotated to drive the pressure block 16 on the top of the support bracket 7 to fix the circuit board assembly 8 inside the support bracket 7, thereby realizing the support and fixing function.

[0026] The mounting base 5 has a lower heat dissipation hole 13 on the top, a heat sink 20 on the bottom, and a cooling fan 10 on the bottom.

[0027] A heat sink 20 is installed at the bottom of the mounting base 5, and a cooling fan 10 is installed inside the heat sink 20 at the bottom of the mounting base 5. The cooling fan 10 is connected to the top of the mounting base 5 through the lower heat dissipation hole 13.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, by setting up an accelerated heat dissipation structure, the cooling fan 10 inside the heat sink 20 at the bottom of the mounting base 5 is started during use. The cooling fan 10 extracts heat from inside the mounting base 5 and the heat sink 20 at the bottom of the mounting base 5 through the lower heat dissipation hole 13. The heat on the mounting base 5 is discharged through the bottom of the cooling fan 10 and through the heat dissipation hole slot 2 on the power box 1 at the top of the mounting base 5, accelerating the airflow inside the power box 1 for heat dissipation, thereby realizing the accelerated heat dissipation function.

[0029] The top of the mounting base 5 is provided with connecting slots 6 around the top. The top of the mounting base 5 is covered with a power box 1. The bottom of the power box 1 is provided with connecting screws 4 around the bottom. The power box 1 is provided with snap-fit ​​slots 3 on both sides of the outside. The power box 1 is covered with an antistatic filter 17. The power box 1 is provided with a metal layer 18 inside. The power box 1 is provided with heat dissipation slots 2 on the outside. The inner wall of the power box 1 is coated with an insulating varnish layer 19.

[0030] The antistatic filter 17 is snapped into the snap-fit ​​slot 3 outside the power box 1. The antistatic filter 17 covers the outside of the power box 1. The antistatic filter 17, the metal layer 18 and the insulating varnish layer 19 are connected in sequence. The insulating varnish layer 19 is coated on the inner wall of the metal layer 18. The power box 1 is connected to the inside of the power box 1 through the heat dissipation slot 2.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, by setting up a dustproof and insulating protective structure, when in use, the antistatic filter 17 is covered on the outside of the power box 1, and the antistatic filter 17 is snapped into the snap-fit ​​slot 3 on the outside of the power box 1. The inside of the power box 1 is coated with an insulating varnish layer 19, which makes the power box 1 insulating and dustproof, preventing damage to the circuit board assembly 8 inside the power box 1 from the outside of the power box 1 through power supply, thereby achieving the dustproof and insulating protective function.

[0032] Working principle: In use, the movable stop 12 retracts inside the fixed base 14 via the telescopic spring 15, allowing the circuit board assembly 8 to be inserted into the four sets of support brackets 7 on the top of the mounting base 5 on both sides. One side of the circuit board assembly 8 then contacts the limiting plate 9 on the right side of the top of the mounting base 5. Next, the upper fixing knob 11 on the top of the support bracket 7 is rotated, causing the pressure block 16 on the top of the support bracket 7 to fix the circuit board assembly 8 inside the support bracket 7. Then, the power box 1 is placed over the top of the mounting base 5 to cover the circuit board assembly 8. Finally, the connecting screw 4 is inserted into the bottom of the power box 1 and threaded into the connecting hole slot 6 inside the mounting base 5. By covering the outside of the power supply box 1 with the antistatic filter 17, the antistatic filter 17 is snapped into the snap-fit ​​slot 3 on the outside of the power supply box 1, thus fixing the antistatic filter 17. During use, the cooling fan 10 inside the heat sink 20 at the bottom of the mounting base 5 is started. The cooling fan 10 extracts heat from the inside of the mounting base 5 and the heat sink 20 at the bottom of the mounting base 5 through the lower heat dissipation hole 13, and the heat on the mounting base 5 is discharged through the bottom of the cooling fan 10. The heat dissipation is accelerated by the airflow inside the power supply box 1 through the heat dissipation hole slot 2 on the top of the power supply box 1. The inside of the power supply box 1 is coated with an insulating varnish layer 19, which makes the power supply box 1 insulating and dust filtering.
