Description
Technical field
The utility model relates to biological exoskeleton device field, in particular to a kind of knee joint servomechanism.
Background technique
In physical activity, knee joint is that human body bears burdens maximum position, especially when human body is squatted down to knee joint
The burden of generation is particularly acute, and knee joint is also easy to fatigue.In ectoskeleton power-assisted field, people always want to obtain a kind of knee
Joint assistance mechanism does not need additional dynamic structure, it is only necessary to be completed with spring energy-storage original part；General knee joint helps
Force mechanisms can all use spring, and spring can generate power-assisted effect by compression in human body walking.
In the prior art, general knee joint servomechanism carries out power-assisted in use, since servomechanism mostly uses spring
When response it is very fast, support force may be insufficient when or spring strength larger to the pressure of muscle is smaller.
Utility model content
The purpose of this utility model is that: a kind of knee joint servomechanism is provided, solves general knee joint power-assisted
Mechanism carries out responding very fast, or bullet larger to the pressure of muscle when power-assisted in use, since servomechanism mostly uses spring
The problem that support force may be insufficient when spring force amount is smaller.
The technical solution adopted in the utility model is as follows:
A kind of knee joint servomechanism, including waistband and the exoskeleton system being connected on waistband, the exoskeleton system
Including the two thigh support components in left and right, the thigh support component include thigh support bar and with hinged small of thigh support bar
Leg support rod and the sole connecting with leg support bar further include that cylinder and cylinder and the air bag being arranged in sole and accumulation of energy fill
It sets, described cylinder one end and thigh support bar are pivotally connected, and the other end and leg support bar are pivotally connected；
It further include tracheae, one end of tracheae connects air bag, and the other end connects cylinder, wherein the air bag in the sole of left leg
It is connect with the cylinder of right leg, the air bag in the sole of right leg is connect with the cylinder of left leg.
When human body walking, waistband is fastened in loins, and thigh support bar is bound on thigh, and leg support bar is bound in shank
On, cylinder is hinged between thigh support bar and leg support bar.Air bag is equipped in sole, air bag gas circuit leads to cylinder.Left and right
Air bag alternately supplies, i.e., right crus of diaphragm spirit capsule transtracheal controls left leg cylinder, and left foot spirit capsule transtracheal controls right leg cylinder.
When work, right crus of diaphragm heelstrike, lift by left heel, and right crus of diaphragm air bag starts to compress at this time, work of the left foot in energy storage equipment
With lower gasbag air-breathing, left leg cylinder is started to shrink.Right crus of diaphragm heelstrike while, right crus of diaphragm bottom energy storage equipment be pressurized carry out energy storage.
Heelstrike, right heel lift, left foot air bag compresses left foot at this time, and right crus of diaphragm air bag under the action of energy storage equipment is inhaled
Gas, right leg cylinder start to shrink.Left foot heelstrike while, left foot bottom energy storage equipment be pressurized carry out energy storage.
Further, the sole is made of lower sole and upper sole, wherein lower sole it is identical with upper sole shape and under
Sole front end is connect with the front end of upper sole.Lower sole and upper sole are articulated and connected, that is, sole is descended to fix with upper sole toe cap.
Further, the air bag and energy storage equipment are arranged between lower sole and upper sole.
Further, the energy storage equipment includes the baffle and support plate perpendicular to lower sole, the baffle and support plate
Between be provided with the guide rod vertical with baffle and support plate, the direction of the guide rod and the heel of sole are directed toward the side of toe cap
It further include the guide sleeve being nested in outside guide rod to identical, the guide sleeve is connect by hinge with upper sole, and guide sleeve also leads to
Spring is crossed to connect with baffle.
Further, the baffle and support plate are located at the both ends of guide rod, and wherein it is close to be located at guide rod for baffle
One end of heel.
Further, the spring increases the active force of guide sleeve with the spacing between lower sole and upper sole and subtracts
It is small.The present apparatus can control the angle between upper and lower sole, thus ensure that every sole air bag pressured state is consistent,
To which the active force that the air pressure for generating air bag generates cylinder remains the same, cylinder piston when avoiding different people walking
The inconsistent problem of bar retraction stroke.
Energy storage equipment using the above structure, since guide sleeve is connect by hinge with upper sole, while guide rod is fixed
On lower sole, when heelstrike, the spacing between upper sole and lower sole reduces, and the angle on hinge and ground reduces, hinge
Chain belt action-oriented set is axially moved along guide rod, stretching or compressed spring；When heeloff, stretches or the spring of compression is multiple
Position, driving guide sleeve along guide rod be axially moved, guide sleeve under the action of the spring, it is in the horizontal direction project to upper sole
Hinged place is close, and the angle on hinge and ground increases, and increases the spacing between sole and lower sole, completes to reset.
Further, the front-end and back-end of the sole are provided with bandage.It completes to fix convenient for sole and sole.
Further, the middle section of the tracheae is fixed on waistband.If the middle section of tracheae is not fixed on waistband, and
Tracheae is directly directly connected to cylinder, the air bag due to being left leg is connect with the cylinder of right leg, and the air bag of right leg and left leg
Cylinder connection, then action when tracheae be easy to trip user, use is more inconvenient.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. a kind of knee joint servomechanism of the utility model also has cylinder, gas not only with spring as servomechanism
With certain damping when cylinder acts, solves general knee joint servomechanism in use, since servomechanism mostly uses bullet
Spring carries out responding the problem very fast, support force may be insufficient when or spring strength larger to the pressure of muscle is smaller when power-assisted
2. a kind of knee joint servomechanism of the utility model, when work, right crus of diaphragm heelstrike, lift by left heel, at this time right crus of diaphragm
Air bag starts to compress, and left foot air bag air-breathing under the action of energy storage equipment, left leg cylinder starts to shrink.Right crus of diaphragm heelstrike same
When, right crus of diaphragm bottom energy storage equipment, which is pressurized, carries out energy storage；Heelstrike, right heel lift, left foot air bag compresses left foot at this time, and right crus of diaphragm exists
Air bag air-breathing under the action of energy storage equipment, right leg cylinder start to shrink.Left foot heelstrike while, left foot bottom energy storage equipment by
Pressure carries out energy storage.
