Driving part device of robot bus

The utility model discloses a robot bus driving part device which comprises a base, a driving part body is installed in the middle of the top of the base, a sound insulation protective shell is arranged on the edge of the top of the base, and heat dissipation holes are evenly formed in the two sides of the sound insulation protective shell. And first mounting bins are mounted on the two sides of one end in the sound insulation protective shell. The heat dissipation holes are blocked by the dustproof plate, the effects of protection, dust prevention and the like of the sound insulation protection shell in a conventional state can be fully guaranteed, when the temperature in the sound insulation protection shell rises to a certain amplitude, inert gas in the inert gas air bag can expand to drive the dustproof plate to further slide towards the interior of the first installation bin, and the heat dissipation effect is improved. The through holes are made to coincide with the heat dissipation holes, so that exter
