Summary of the invention
The objective of the invention is to be to overcome above-mentioned weak point, a kind of intensity height, light weight, good springiness, the comfortable carbon fiber double-side elastic all-terrain artificial feet plate of walking are provided.
For achieving the above object, the present invention adopts following design:
A kind of carbon fiber double-side elastic all-terrain artificial feet plate, comprise syndeton, be characterized in: also comprise two lower plates, upper plate, the U-shaped antitrope, fixedly connected with Os Draconis behind the U-shaped with the U-shaped antitrope between the Os Draconis behind the U-shaped, described upper plate and two lower plates, and behind U-shaped antitrope and the U-shaped keel structure opening all backward; Be used for when heel from weight-bearing phase to liftoff phase transition and forefoot from weight-bearing phase during to liftoff phase transition, Os Draconis and U-shaped antitrope will discharge self energy stored respectively behind the U-shaped, help false foot to finish and push off action.
Two lower plates and upper plate are the arcuate structure of the normal sole of imitation, wherein, two lower plates then are made up of two blocks of identical bionical arcuate structure plates, and the branch interdigit is left in the centre, make false foot automatically adapt to rugged pavement structure, strengthen the safety of false foot and functional.
The lower end of Os Draconis all has gap behind U-shaped antitrope and the U-shaped, and is connected with two lower plates by gap.
The mid portion of two lower plates is provided with projection, the wearer that makes false foot in the process of walking, no matter be from the phase of landing to the weight-bearing phase transition, still from weight-bearing phase to liftoff phase transition, all can make gait more steadily, graceful, nature.
The present invention has following advantage:
1, when heel from phase of landing during to the weight-bearing phase transition, Os Draconis are compressed behind the opening U-shaped backward, the impulsive force that produces in the time of can absorbing heel and contact with ground, thus influence alleviated to deformed limb, knee joint, hip joint and spinal column, and Os Draconis can storage power behind the compressed U-shaped simultaneously.From weight-bearing phase during to liftoff phase transition, the Os Draconis bounce-back discharges energy behind the U-shaped, helps heel to finish liftoff action at heel.
2, for farthest reducing the energy loss in each gait cycle, improve the energy storage ratio of false foot, designed opening U-shaped antitrope backward at the forefoot place, after heeloff, forefoot from the phase of landing to the weight-bearing phase transition, this moment, the U-shaped antitrope was compressed and storage power, when forefoot from weight-bearing phase during to liftoff phase transition, the bounce-back of U-shaped antitrope releases energy, and helps forefoot to finish liftoff action.Thereby the energy loss of each gait cycle can be dropped to minimum, even can not feel tired when making wearer carry out the outdoor activities of long period yet.
3, at the lower plate design aspect of false foot, adopted two blocks of identical bionical arcuate structure plates, thereby made false foot have branch toe characteristic, can adapt to rugged pavement structure automatically, strengthened the safety of false foot and functional.
4, the front and rear surfaces of two lower plates all adopts arcuate structure, mid portion has projection, thereby the wearer that can make false foot in the process of walking, no matter be from the phase of landing to the weight-bearing phase transition, still be to liftoff phase transition from weight-bearing phase, all belong to the dynamic transition, gait can more steady, graceful, nature.
5, the agent structure of whole foot core for artificial foot has adopted carbon fibre composite in light weight, that intensity is high, the life-span is long to make, and meets to guarantee false foot function and realize the light-weighted design concept of false foot.
