An output shaft of the electromotor is in linkage connection with an input shaft of the oil-free vortex type air compressor through a coupling and an elastic sheet is arranged between two connecting ends of the coupling. The disclosed structure of the oil-free vortex type air compressor unit for the new energy automobile cancels a belt pulley on the output shaft end of the electromotor and a belt pulley on the input shaft end of the vortex type air compressor and the belts are replaced by the flexible coupling for directly connection and transmission. Therefore, the oil-free vortex type air compressor unit for the new energy automobile is simple and compact in structure, small in occupied space of equipment which is connected with the same shaft in a flexible mode, high in transmission efficiency, stable in using performance and low in noise and is capable of eliminating potential safety hazards radically. In addition, the starting and stopping of the frequency changer are controlled through the pressure switch so that the operation of the air compressor unit is controlled and the whole gas circuit system pressure can be compensated. Due to the fact that continuous operation of a traditional air compressor of a whole automobile is upgraded to intermittent operation, the oil-free vortex type air compressor unit for the new energy automobile is energy-saving and environment-friendly.
