Commercial vehicle single-row cab floor, manufacturing method and commercial vehicle

The invention relates to a commercial vehicle single-row cab floor, a manufacturing method and a commercial vehicle, the commercial vehicle single-row cab floor comprises a floor body, the floor body comprises a left floor body, a middle floor body and a right floor body which are integrally formed through punching, the middle floor body is used for being arranged above an engine, and the middle floor body protrudes upwards relative to the left floor body and the right floor body; the longitudinal beam is fixed below the left floor and the right floor; and the boundary beams are fixed on the edges of the left floor and the right floor. Due to the fact that the left floor, the middle floor and the right floor are combined into one floor and are integrally punched and formed through the punching machine, the number of floor parts is reduced, the material utilization rate is high, the manufacturing and maintenance management cost is reduced, welding is not needed through punching forming, the floor quality is gu
