And reduce elastic impact in motor process for the type lower limb knee joint artificial limb p of going down on one's knees.
Buffer stopper 11 and buffer stopper 21 are all using elastic plastic material, such as rubber or polyurethane etc..
The elasticity below describing the present invention is gone down on one's knees the operating principle of type lower limb knee joint artificial limb p and process.
As shown in figure 4, the elasticity of the present invention is gone down on one's knees, type lower limb knee joint artificial limb p passes through stump socket connector 1 and connects
Connected by chamber h, be connected with prosthetic foot connecting rod k01 and prosthetic foot k by prosthetic foot connector 2 meanwhile.
When tiptoe contacts to earth, elasticity goes down on one's knees type lower limb knee joint artificial limb p can be by faced by the driving force f2 of hip joint and ground
The effect of the counteracting force r2 of tiptoe, this pair of power acts on elasticity and goes down on one's knees type lower limb knee joint artificial limb p, so that joint of artificial limb is bent
(as shown in Figure 5), drives whole artificial leg action, reaches walking purpose.
In embodiment as shown in Figure 4 and Figure 6, when heel contacts to earth, the elasticity type lower limb knee joint artificial limb p that goes down on one's knees can be subject to
To the effect of the driving force f1 of hip joint and the counteracting force r1 of heel faced by ground, postero lateral arm 4 is in the effect of this pair of active force
In axle 41, the two ends of axle 41 slide into the lower end of straight-line groove 601a in the straight-line groove 601a on sliding shoe 601 to lower applying power;Afterwards
Side lever 4, under the restriction that axle 41 slides along straight-line groove 601a, according to certain track motion, drives knee joint artificial limb p bending.?
When postero lateral arm 4 moves according to certain track, the jacking block 602 of elastic part of going down on one's knees, will be to postero lateral arm in the presence of spring 604
4 applying one active forces upwards, this active force changes in the presence of spring 604.So when heel contacts to earth, artificial limb closes
Section is gone down on one's knees realizing elasticity function.
Meanwhile, rotate adjustment block 605 by rotating the circular hole 605a in adjustment block 605, to adjust the precommpression of spring 604
Amount, thus meet different patients go down on one's knees to elasticity the requirement of intensity.
In embodiment as shown in figs. 4 and 7, when heel contacts to earth, the elasticity type lower limb knee joint artificial limb p that goes down on one's knees can be subject to
To the effect of the driving force f1 of hip joint and the counteracting force r1 of heel faced by ground, postero lateral arm 4 is in the effect of this pair of active force
In axle 41, the two ends of axle 41 slide into the lower end of curved groove 601b in the curved groove 601b on sliding shoe 601 to lower applying power;Afterwards
Side lever 4, under the restriction that axle 41 slides along curved groove 601b, according to certain track motion, drives knee joint artificial limb p bending.?
When postero lateral arm 4 moves according to certain track, the jacking block 602 of elastic part of going down on one's knees, will be to postero lateral arm in the presence of spring 604
4 applying one active forces upwards, this active force changes in the presence of spring 604.So when heel contacts to earth, artificial limb closes
Section is gone down on one's knees realizing elasticity function.
It will be appreciated by those skilled in the art that above-mentioned diagramatic content and embodiment are only used for explaining the present invention not for right
It makes any restriction.For example, elastic buffering mechanism is not limited to the structure illustrating, as long as but this elastic buffering mechanism energy
Enough realizations apply elastic acting force to the lower end of postero lateral arm.
