A man-machine contact force detection device of a lower limb rehabilitation training robot comprises a wearing ring matched on the lower limb of a human body, outer ring plates and force detection modules, the outer ring plates are symmetrically arranged on the two sides of the wearing ring, and at least two sets of force detection modules are arranged between each side face of the wearing ring and the corresponding outer ring plate. The outer ring plates are installed on the connecting block through a length adjusting assembly, the length adjusting assembly comprises two length adjusting screw rods, and the two length adjusting screw rods are fixedly connected to the two sides of the connecting block, connected with the corresponding outer ring plates respectively and fixed through adjusting nuts. According to the scheme, a novel wearable sensing mechanism for obtaining man-machine contact force through differential pressure detection and an intelligent testing device for signal conversion and processing are
