The invention belongs to the technical field of automobiles, and discloses a ventilation plug assembly structure, a drive axle assembly and a vehicle. The ventilation plug assembly structure is used for communicating an inner cavity of a drive axle assembly with an external space and comprises an axle housing ventilation plug and a front housing ventilation plug. The axle housing ventilation plug comprises a first ventilation pipe and a first pipe connector, the first pipe connector is installed on an axle housing of the drive axle assembly and communicated with an inner cavity of the drive axle assembly, the first ventilation pipe is communicated with the first pipe connector in a crossed mode, and a ventilation opening of the first ventilation pipe is formed in the side, away from the axle housing, of the first ventilation pipe. The front shell ventilation plug comprises a second ventilation pipe and a second pipe connector, the second pipe connector is installed on a front shell of the drive axle assembly and communicated with an inner cavity of the drive axle assembly, the second ventilation pipe is communicated with the second pipe connector in a crossed mode, and a part of the second pipe connector extends into the second ventilation pipe. According to the ventilation plug assembly structure, the ventilation function of the drive axle assembly can be achieved, and muddy water can be prevented from entering an inner cavity of the drive axle assembly.
