Intelligent oil-electricity all-in-one machine of electric vehicle range extender

The invention relates to the field of electric vehicle range extenders, in particular to an intelligent oil-electricity all-in-one machine of an electric vehicle range extender. The technical problem that in the using process of an existing oil-electricity all-in-one machine, due to the fact that a motor is not switched into driving in full time, when an electric vehicle runs at a low speed or in a short distance, full-electric mode driving only depending on electric power is difficult to achieve is solved. According to the technical scheme, the intelligent oil-electricity all-in-one machine of the electric vehicle range extender comprises a support assembly, an engine assembly, an adjusting assembly, a rotating assembly and a power generation assembly; an engine assembly is installed at the upper end of the support assembly. An adjusting assembly is installed on the engine assembly. A special hub power generation structure is arranged to replace an original direct switching type structure, so that the proble
