[0035] The vehicle-mounted boost-down circuit board structure with auxiliary cleaning function in a preferred embodiment of the utility model is as follows Figure 1-Figure 5 As shown, it includes a vehicle-mounted buck-boost circuit board assembly 1, which includes a circuit board body 2 and a bottom dust box 3 installed on the bottom surface thereof. Mounting threaded holes are provided at the four corners of the top surface of the circuit board body 2, and connecting platforms 24 are integrally formed at the four corners of the inner cavity of the bottom dust box 3. The top surface of the connecting platform 24 has holes that are the same as the mounting threaded holes on the top surface of the circuit board body 2. When the circuit board body 2 and the bottom dust box 3 need to be connected together, the circuit board body 2 is connected to the connecting platform 24 of the bottom dust box 3 by bolts, thereby facilitating the installation and disassembly of the circuit board body 2 and the bottom dust box 3. When the circuit board body 2 needs to be installed in an external vehicle-mounted installation chamber, the bottom dust box 3 is installed in the external vehicle-mounted installation chamber by bolts, and the circuit board body 2 can be installed.

[0036] In this embodiment, an auxiliary cleaning structure 4 is provided on the top surface of the circuit board body 2, and the auxiliary cleaning structure 4 includes a U-shaped negative pressure dust suction pipe 7 bonded to the top surface of the circuit board body 2 and capable of spanning between different electronic components, a micro vacuum pump 5 connected by a connecting pipe 6, and a U-shaped bracket detachably arranged in an inverted manner above the U-shaped negative pressure dust suction pipe 7, a lifting drive block 10 is provided on the upper part of the U-shaped bracket, and a resonant spring member 11 is connected below the lifting drive block 10 and between the inner walls of the U-shaped bracket, and the lifting drive block 10 is lifted and reciprocated to abut against the resonant spring member 11, so that the resonant spring member 11 transmits vibration to the vehicle-mounted boost circuit board assembly 1 through the U-shaped bracket and the U-shaped negative pressure dust suction pipe 7, and a plurality of negative pressure dust suction holes 13 are symmetrically opened on the outer wall of one end of the U-shaped negative pressure dust suction pipe 7 close to the vehicle-mounted boost circuit board assembly 1.

[0037] In this embodiment, the U-shaped bracket includes two mounting uprights 17 symmetrically installed on the top of the U-shaped negative pressure vacuum tube 7 and a top rod 8 welded to the top of the two mounting uprights 17. A pen-shaped cylinder 9 is installed on the inner wall of the top rod 8 by screws. The bottom end of the bottom piston rod of the pen-shaped cylinder 9 is fixedly connected to the lifting drive block 10. The lifting drive block 10 has an elliptical structure. Both ends of the lifting drive block 10 are provided with push-pull ends 20 for freely loosening the push-pull resonant spring member 11. The design of the push-pull end 20 is conducive to the free sliding and rebounding of the resonant spring member 11.

[0038] In this embodiment, the micro vacuum pump 5 is fixedly mounted on the top surface of the circuit board body 2, and an exhaust hole 12 for sealing and installing the connecting tube 6 is opened on the outer wall of one end of the U-shaped negative pressure dust suction tube 7. After the micro vacuum pump 5 is turned on, the dust accumulated on the top surface of the circuit board body 2 is sucked away by negative pressure through the connecting tube 6 and the U-shaped negative pressure dust suction tube 7, and the tail end of the micro vacuum pump 5 is provided with a dust exhaust pipe (not shown in the figure) for dust exhaust, which extends to the outside of the installation box of the circuit board body 2 for dust exhaust, so that the dust can be discharged, thereby achieving the cleaning effect of the circuit board body 2.

[0039] In this embodiment, when the pen-shaped cylinder 9 drives the lifting drive block 10 to lift, the lifting drive block 10 can push the resonance spring part 11. When the resonance spring part 11 gradually loses the push and pull during the sliding friction of the outer wall of the lifting drive block 10, the resonance spring part 11 will rebound, and vibration will be generated under the free rebound force of the resonance spring part 11. The vibration is transmitted from the U-shaped bracket and the U-shaped negative pressure dust suction pipe 7 to the vehicle-mounted boost and boost circuit board assembly 1, so that the vehicle-mounted boost and boost circuit board assembly 1 will bounce up the accumulated dust due to the vibration, which is helpful for further dust suction, thereby reducing the problem of the accumulated dust that cannot be sucked away, thereby improving the cleaning effect and efficiency. When the lifting drive block 10 pulls the resonance spring part 11, the resonance spring part 11 will also rebound and transmit the vibration force to the vehicle-mounted boost and boost circuit board assembly 1. This can be repeated many times to improve the cleaning efficiency.

[0040] In the present embodiment, the top outer walls of the tube bodies on both sides of the U-shaped negative pressure vacuum tube 7 are evenly and integrally connected with a plurality of plug-in inner cylinders 18 for fitting and plugging into the mounting poles 17. The plug-in inner cylinders 18 are connected to the mounting poles 17 via removable bolts 19. The design of the plurality of plug-in inner cylinders 18 helps to select the installation position of the mounting poles 17 according to actual needs. When the top surface of the circuit board body 2 has an installation position for blocking the resonance spring member 11, the installation position of the mounting pole 17 is selected and replaced to meet the use of different circuit board bodies 2.

[0041] In this embodiment, the bottom dust box 3 has a movable cleaning brush 23 for cleaning the bottom surface of the vehicle-mounted boost circuit board assembly 1. The inner cavity of the bottom dust box 3 has a detachable adsorption filter 21 for adsorbing fallen dust, and the detachable adsorption filter 21 is connected to the bottom dust box 3 by screws. An electric push-pull rod 22 is fixedly installed above the detachable adsorption filter 21 and on the inner wall of the bottom dust box 3. The free end of the electric push-pull rod 22 is fixedly connected to the bottom shell of the movable cleaning brush 23. When the electric push-pull rod 22 pushes and pulls the movable cleaning brush 23, the bristle end of the movable cleaning brush 23 rubs against the bottom surface of the vehicle-mounted boost circuit board assembly 1 to clean the dust.

[0042] In this embodiment, when it is necessary to clean the bottom surface of the circuit board body 2, the electric push-pull rod 22 drives the mobile cleaning brush 23 to move, so that the bristle end of the mobile cleaning brush 23 rubs and cleans the bottom surface of the vehicle-mounted boost circuit board assembly 1, so that the dust falls onto the detachable adsorption filter 21 and adsorbs the dust. When it is necessary to disassemble and centrally process the dust on the detachable adsorption filter 21, the detachable adsorption filter 21 can be disassembled by removing the screws, so that the dust on the bottom surface of the circuit board body 2 can be cleaned, thereby improving the service life of the circuit board body 2.

[0043] In this embodiment, a detachable sealing end cap 14 is provided at the free end of the U-shaped negative pressure dust suction tube 7, and the inner wall of the free end of the U-shaped negative pressure dust suction tube 7 has internal threaded teeth 15. An external threaded tube 16 that can be threadedly connected to the internal threaded teeth 15 is integrally formed on the inner wall of the detachable sealing end cap 14. When the area of ​​the circuit board body 2 that needs to be vacuumed is long and the U-shaped negative pressure dust suction tube 7 needs to be extended, the detachable sealing end cap 14 is removed and connected to an external extended dust suction tube (not shown in the figure) by threaded connection, so as to meet the use of different circuit board bodies 2.

[0044] In this embodiment, a PLC for controlling the opening and closing of each electronic device is also installed on the top surface of the circuit board body 2, and the PLC model can be selected according to actual needs.

[0045] Working principle:

[0046] The vehicle-mounted boost circuit board structure with auxiliary cleaning function has a circuit board body 2 connected to a connecting platform 24 of a bottom dust collection box 3 by bolts. When the top surface of the circuit board body 2 needs to be cleaned, the micro vacuum pump 5 is turned on and operated to vacuum away the dust accumulated on the top surface of the circuit board body 2 through a connecting pipe 6 and a U-shaped negative pressure suction pipe 7, and the dust is discharged through the dust discharge pipe. When the pen-shaped cylinder 9 drives the lifting drive block 10 to rise and fall, the lifting drive block 10 can push the resonance spring member 11. When the resonance spring member 11 is on the lifting drive block 1 When the outer wall gradually loses its push and pull during the sliding friction, the resonant spring member 11 will rebound, and vibration will be generated under the free rebound force of the resonant spring member 11, and the vibration will be transmitted from the U-shaped bracket and the U-shaped negative pressure dust suction pipe 7 to the vehicle-mounted boost and buck circuit board assembly 1, so that the vehicle-mounted boost and buck circuit board assembly 1 will bounce up the accumulated dust due to the vibration. When the lifting drive block 10 pulls the resonant spring member 11, the resonant spring member 11 will also rebound and transmit the vibration force to the vehicle-mounted boost and buck circuit board assembly 1. This can be repeated many times to improve the cleaning efficiency.

[0047] When it is necessary to clean the bottom surface of the circuit board body 2, the electric push-pull rod 22 drives the mobile cleaning brush 23 to move, so that the bristle end of the mobile cleaning brush 23 rubs and cleans the bottom surface of the vehicle-mounted boost circuit board assembly 1, so that the dust falls onto the detachable adsorption filter 21 and adsorbs the dust.
