The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
Core concept of the present utility model is to advocate a kind of theory of design, and the structure of corresponding product design trend standardized component is combined into the structural member of various transmissions by each module, creates series of products.This utility model mainly is in the design of mechanical structured member, sets up the modular design system, and myoelectric hand's mechanical part structural member is divided into two kinds of series, and a kind of series is to be fit to Asian hand-type; Another kind is the hand-type that is fit to people from continent of Europe, the United States.Overall dimensions is selected the overall dimensions (because of their product is accepted by most of country in the world) of in the world maximum artificial limb orthosis manufacturer OTTO BOCK for use, makes various standard components and is convenient to be fit in the world that the people with disability of most of colony selects for use.
See also shown in Fig. 1 a to Fig. 3 b, this myoelectric hand's mechanical hand header structure and adnexa, comprise composition forefinger 1 and middle finger 2, thumb 3, hands frame plate 4 at hand, connecting rod 5, forefinger, thumb shaft assembly 16, preposition decelerator 17, base 18, described preposition decelerator 17 is fixedly set on the hands frame plate 4, described base 18 is fixedly set in hands frame plate 4 bottoms, wherein, described hands frame plate 4 is supported at three point formula structure, and the root of described forefinger 1 and middle finger 2, thumb 3 all flexibly connects with described hands frame plate 4 by connecting rod 5 and forefinger, thumb shaft assembly 16.
In actual applications, the myoelectric hand of Aisan's hand-type, finger (thumb 3, middle finger 2 and forefinger 1) adopts three finger structures commonly used, size apery body finger ratio, and and international joint (promptly adopting the standard size of OTTO BOCK company).4 fens large sizes (man style) of hands frame plate, medium size (woman style), small size (child).
Wherein the man style of the bottom supported at three point formula that designs for this utility model of Fig. 1 a and 1b at hand, its compact appearance can be included in the glove fully, profile can not given prominence to.Hands shape is attractive in appearance; The medium size that Fig. 2 a and 2b design for this utility model at hand woman style, its advantage is that hands shape is small and exquisite, is satisfied with to decorate and function has concurrently simultaneously, and changes to point and just can form the trumpeter.The myoelectric hand of European's hand-type that Fig. 3 a and 3b design for this utility model, myoelectric hand's profile that all overall dimensions of hand all adopt German OTTO BOCK company to produce, running part is the same with above-mentioned structure, is convenient to production, only need change profile, become a kind of product again.So just embodied modularity, reduced part, reduced cost, product is more oversimplified, rationalized.
See also Fig. 4 again to shown in Figure 6, the bottom of the base at hand of this myoelectric hand's mechanical hand header structure and adnexa is connected with myoelectric hand's wrist unit 6 by revotating card splice grafting header structure, wherein this revotating card splice grafting header structure can comprise the rotation trip 7 bottom being arranged at hand, the rotation draw-in groove 61 that is arranged at corresponding position on the wrist unit 6 and engaging control knob 62, described rotation trip 7 revotating cards are located in this rotation draw-in groove 61, and by these engaging control knob 62 engaging location.
In another kind of embodiment of the present utility model, the revotating card splice grafting header structure of this myoelectric hand's mechanical hand header structure and adnexa also can comprise the rotation draw-in groove bottom being arranged at hand, the rotation trip that is arranged at corresponding position on the wrist unit and engaging control knob, described rotation trip revotating card is located in this rotation draw-in groove, and by this engaging control knob engaging location.
By adding this revotating card splice grafting header structure on hand, this structure can make at hand and be connected fast with wrist unit, thereby making at hand easily, structural member is connected with wrist decelerator, arm tube, circuit box, and be convenient to and its link mounting or dismounting, easy for installation, be convenient to maintenance, handled easily designs more humane.
Problem is arranged at hand,, just be separable into two parts and keep in repair, be easy to use without any need for instrument; And domestic product all is to adopt screw to connect in the prior art, need look for instrument to dismantle and install during maintenance, and the product that OTTOBOCK company is only arranged in the world also is the rotating adaptor structure of freeing by the position that rotates to the power pine always, and its manufacturing cost is higher.And this kind structure of the present utility model is as long as one remove button, and a rotation just can make and separate with wrist at hand, and is not only simple in structure, and production cost is low, the most important thing is that the wrist space hold is few, has enlarged patient's fitting limit.
See also shown in Figure 7ly again, the end of the forefinger 1 of this myoelectric hand's mechanical hand header structure and adnexa and middle finger 2, thumb 3 all is arranged with adnexa fingerstall 8, and the oral area 81 of described fingerstall 8 is the bevel shape.In actual applications, this fingerstall 8 adopts the POM medical plastic, and is not only nontoxic, and toughness intensity is good.Simple trade mark can be designed in the kneading surface of finger tip, promptly beautifully is convenient to die sinking again, economical rationality, thus reduced the cost of mould.
See also Fig. 8 a again to shown in Figure 9, can also include adnexa nameless 9 and little finger of toe 10 in the structure at hand of this myoelectric hand's mechanical hand header structure and adnexa, described nameless 9 comprise that at least two refer to section 91, and each section of finger 91 is connected in series successively by tinsel and is connected with hands frame plate 4; Described little finger of toe 10 comprises at least that also at least two refer to section 101, and each section of finger 101 is connected in series successively by tinsel and is connected with the hands frame plate.
In actual applications, can adopt the above-mentioned finger section of iron wire polyphone, thereby form the third finger 9 and little finger of toe 10, because simple in structure, thereby lowered cost, and assembled up and very convenient, be contained in the glove to be connected and to shirk all and be easy to myoelectric hand, not only cost is low, and economy and durability, and is easy to operate.
Above-mentioned myoelectric hand's mechanical hand header structure and adnexa have been adopted, because it utilizes the structural design theory of standardized component, be combined into the structural member of various transmissions by each module, thereby set up the modular design system, it is versatile and flexible to choose use, wherein each kind of standard component is suitable in the world that the people with disability of most of colony selects for use, thereby reduced production cost; Moreover, this convenience quick for installation, long service life, production cost is lower, applicable surface is comparatively extensive, brings great convenience for people's life, working and learning.
In this description, this utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
