When standing, keep thigh parts 101 vertically, during now dead in line with shank body 202 of thigh parts 101, the first adhesive Magnet 102 and the adhesive mutually of the second adhesive Magnet 208, shank body 202 and sole assembly 301 pairs of thigh parts 101 and human body play a supportive role.Even if when shank body 202 offsets, make lever shell fragment 203 produce skew, now lever shell fragment 203 resets by shank body 202.
During seat, make thigh parts 101 form sitting posture around shank body 202 certain angle that rotates backward, now the first adhesive Magnet 102 and the second adhesive Magnet 208 are separately.
During walking, use this motion artificial limb with right lower limb, and left lower limb is normal lower limb is example.
When left lower limb be supporting leg, right lower limb step time, the adhesive mutually of the first adhesive Magnet 102 and the second adhesive Magnet 208, the dead in line of thigh parts 101 and shank body 202, thigh parts 101 and shank body 202 all tilt backwards.First the heel position of sole assembly 301 lands, and now sole shell fragment 308 compresses and plays cushioning effect, and sole is imitated meat pad spring 309 and heel and imitated meat pad spring 310 and be in compressive state.
Thigh parts 101 apply pressure by shank body 202 to sole assembly 301, now thigh parts 101 travel forward, shank body 202 rotates forward around sole assembly 301 simultaneously, and lever shell fragment 203 still tilts backwards, this just makes to create angle between lever shell fragment 203 and shank body 202, second back-moving spring 207 is in compressive state, first back-moving spring 206 is in elongation state, power reset response is returned due to the first back-moving spring 206 and the second back-moving spring 207, the upper end of lever shell fragment 203 is rotated forward, then the lower end of lever shell fragment 203 rotates backward, and active force is backward produced to ankle part 303, and then active force is backward produced to sole assembly 301, the counteracting force of sole assembly 301 so forward, whole right lower limb is travelled forward.
When right lower limb moves forward to vertical, step forward left lower limb, now right lower limb is as supporting leg, and left lower limb is front, and right lower limb is rear.
When left lower limb stretch out until left lower limb land and left lower limb as supporting leg time, left lower limb is front, right lower limb is rear, now thigh parts 101 and shank body 202 turn forward, thigh parts 101 lift, rotate forward, make to form angle between thigh parts 101 and shank body 202, the first adhesive Magnet 102 is separated with the second adhesive Magnet 208.
Thigh parts 101 when rotating to the pressure that shank body 202 applies forward, now shank body 202 rotates forward, and lever shell fragment 203 relative after, this just makes to create angle between lever shell fragment 203 and shank body 202, second back-moving spring 207 is in compressive state, first back-moving spring 206 is in elongation state, power reset response is returned due to the first back-moving spring 206 and the second back-moving spring 207, the upper end of lever shell fragment 203 is rotated forward, then the lower end of lever shell fragment 203 rotates backward, and active force is backward produced to ankle part 303, and then active force is backward produced to sole assembly 301, the counteracting force of sole assembly 301 so forward, the counteracting force on this ground makes sole assembly 301 forward, sole assembly 301 is made to depart from ground from sole position gradually to toe position.
After sole assembly 301 departs from ground, whole right lower limb travels forward, continue with left lower limb be supporting leg, the process that steps forward of right lower limb, so move in circles formation walking process.
