The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, hand muscle instrument in the present embodiment comprises motor 1, crank 2, forefinger small crank 9, base plate 4, oscillating bearing 3, connecting rod 7, slide block 6, to referring to motion section 8, four finger motion sections 5, motor 1 places on the motor base (frame), link to each other with crank 2 by shaft joint, the crank other end connects forefinger small crank 9, forefinger small crank 9 with to referring to that motion section 8 is connected, connecting rod 7 is positioned on the base plate 4, adopt oscillating bearing 3 to be connected between crank 2 and connecting rod 7, connecting rod 7 and the slide block 6, the while, four finger motion sections 5 also were connected on the slide block 6.Wherein crank 2 is to connect with jackscrew between the first crank part and the second crank part, for the hole axle cooperates, between the second crank part and the 3rd crank part jump ring is arranged between the 3rd crank part and the four-throw parts.The slide block of four finger motion sections 5 is a sliding pair, settles bearing at slide block, and guide rail is provided with elongated slot, settles pin built-in putting, and pin cooperates with this elongated slot.
As shown in Figure 1, motor 1 places on the motor base (frame), links to each other with crank 2 by shaft joint, and the crank 2 that drives series connection during motor operation rotates simultaneously, drives whole system work.Adopt oscillating bearing to be connected between crank and connecting rod, connecting rod and the slide block, so just guaranteed the realizability of space motion.
As shown in Figure 2, link to each other by jackscrew 22 between the crank system of series connection, unclamp jackscrew and just can regulate easily each crank angle each other, thereby the relative motion between the slide block is changed, so just can realize the different motion of four fingers, as to refer to, wheel refers to etc.Crank is comprised of the first crank 21, the second crank 23, the 3rd crank 25, four-throw 26, connect with jackscrew 22 between the first crank part and the second crank part, for the hole axle cooperates, a jump ring 24 is arranged between the second crank part and the 3rd crank part between the 3rd crank part and the four-throw parts.Unclamping jackscrew just can the direct pull crank, changes its length, thereby realizes the adjusting to the slide block movement stroke.
As shown in Figure 3, the slide block of four finger motion sections is a sliding pair, and its slide block is comprised of four finger slide bodies 31, built-in cover 32, bearing 33, pin 34.In this slider-crank mechanism, slide block moves along a cylindrical slideway, and space mechanism's degree of freedom is not one.Therefore mill out an elongated slot at guide rail, squeeze into pin 34 at built-in cover 32, pin is cooperated with this elongated slot, utilize the motion of pin 34 restriction slide blocks.In seesawing process, finishes smoothly slide block the action such as clench fist for guaranteeing finger, settle bearing 33 at slide block, when slide block movement arrived distal-most end, the finger first knuckle can drive the space that finger enter the bearing below by the rolling of bearing, finishes required motion.
In the human hand movement quality testing and estimating, to referring to that motion is an important indicator, to referring to that motion requires the thumb finger tip to contact with all the other four finger finger tips, therefore just require to drive the parts of finger motion can be point-blank circularly mutually away from close, and in mutual motor process, mutual minimum range should reach zero in theory between them.Adopt the space slider-crank mechanism, make two pairs to refer to that the mutual angles of crank are 180o, then two pairs refer to that slide block just can realize that another slide block is in himself reciprocating most proximal end when the distal-most end of a slide block in its motion, make these two positions be in same point, realized its functional requirement.
