They were hurt when a car was driven into a police van near Stoney Lane, Kidderminster on Tuesday, trapping one officer between the car and van.
One man is charged with assault, inflicting grievous bodily harm with intent to resist arrest and criminal damage. All three, from Wolverhampton, are charged with conspiracy to rob.
They are due before magistrates in Kidderminster later.
