In the present invention, to have realized ankle joint be plane Hooke's hinge two degree of freedom structure in the cooperation of upper undersetting, two rotating shafts, four bearings.I.e. the 5th rotating shaft is through the 6th rotating shaft, and the two ends of the 5th rotating shaft are socketed respectively bearing, and this bearing is arranged on the lug of undersetting; The two ends of the 6th rotating shaft are socketed respectively bearing, and this bearing is arranged on the lug of upper bracket.The design of plane Hooke's hinge ankle joint can realize the front and back of human body ankle and swing, and measures in real time the swing angle of ankle by angular displacement sensor.
In the present invention, foot component structure is for guaranteeing the flexible of ankle joint and foot operation, and when people is dressed, ankle is not interrupted, can measure ankle joint angular displacement and plantar pressure simultaneously, is beneficial to the effective control to foot component.It is flexible, simple in structure that the foot component of the present invention's design has motion, simulates ankle motion completely, is a kind of use novel ankle joint and sole structure and angular displacement and pressure gauge reliable, low cost of manufacture.
The ankle joint mechanism design having at present all adopts spherical hinge structure form, and this structure has run into difficulty to the measurement of ankle joint direction of advance angular displacement, due to the restriction of spherical hinge structure, can not measure this angular displacement, and this control to robot impacts.The foot structure of the present invention's design, ankle joint mechanism has adopted plane Hooke's hinge two degree of freedom structure, before and after, rotating shaft and left and right rotating shaft realize respectively the front and back of sole and swing, and realized by other position around the rotational freedom of shank, in the time of robot control, need the pendulum angle of fore-and-aft direction to measure, therefore angular displacement sensor has been installed this side up, for measuring the pendulum angle before and after sole.Undersetting is arranged on sole, and on undersetting, angular displacement sensor has been installed, and the rotational angle of ankle joint is measured, and has met the measurement requirement of robot to ankle joint angular displacement.Shank expansion link is inserted in upper bracket, and front and back rotating shaft, bearing (ball) cover, bearing are fixed in the lug of upper bracket, realize the front and back rotational freedom of ankle, and realize the measurement of this angle by the angular displacement sensor in rotating shaft before and after being installed to; Left and right rotating shaft is inserted in undersetting fixing, and the axis of front and back rotating shaft is vertical with the axis maintenance of left and right rotating shaft, realizes the degree of freedom that swings of ankle; Between forefoot and hind paw and sole, pressure transducer is installed, and forefoot and hind paw and sole are fixed together, sole contacts with ground, when human body walking, plantar pressure changes, by the detection of pressure transducer, can judge people's walking intention, realize the good control of ectoskeleton supplemental support robot.
