specific Embodiment approach 1

[0007] Specific implementation manner one: such as Figure 1~2 As shown, the passively driven two-degree-of-freedom artificial finger for the handicapped in this embodiment includes a connecting spring frame 1, a base 2, an upper wire 4, a base knuckle upper link 5, and a base knuckle upper stop rod 6. , Lower stop wire 22, base knuckle lower connecting rod 21, base knuckle lower stop rod 20, middle knuckle skeleton 10, middle knuckle connecting rod 15, fingertip 12 and several shafts; connecting the front end of spring frame 1 and base 2 Rotating connection, the upper base phalanx link 5 is arranged above the lower base phalanx link 21, one end of the upper base phalanx link 5 is connected to the base 2 through the first shaft 3, and the lower link 21 of the base phalanx One end is connected to the base 2 through the second shaft 23, the other end of the upper base knuckle link 5 is fixedly connected to the middle of the upper base knuckle stop rod 6, and the other end of the lowe...

specific Embodiment approach 2

[0011] Specific implementation manner two: such as Figure 1~2 As shown, the artificial finger for the disabled in this embodiment also includes a middle knuckle joint cover 7 and a fingertip joint cover 11. The middle knuckle joint cover 7 is arranged on one end of the middle knuckle skeleton 10, and the fingertip joint cover 11 It is set on the other end of the middle phalanx skeleton 10. The middle knuckle joint cover plate 7 and the fingertip joint cover plate 11 maintain the shape of the finger joints during movement. Make the appearance of fake fingers more vivid. Other components and connection relationships are the same as in the first embodiment.

specific Embodiment approach 3

[0012] Specific implementation manner three: such as Figure 1~2 As shown, the artificial finger for the disabled in this embodiment also includes a middle finger upper cover 9 and a middle finger pad 18. The middle finger upper cover 9 is arranged on the upper part of the middle finger skeleton 10, and the middle finger pad 18 is arranged on The lower part of the middle knuckle skeleton 10. The upper cover plate 9 of the middle finger and the pad of the middle finger 18 constitute the shape of the middle finger, which makes the appearance of the fake finger more vivid. Other components and connection relationships are the same as those in the first or second embodiment.

[0013] working principle:

[0014] The fitting shape of the connecting spring frame 1 of the present invention is similar to the shape of the palm, and the artificial finger (the present invention) is connected to the palm (such as figure 1 As shown, B-1 is the palm part, B-2 is the remaining base phalanx), the ...

Abstract

The invention provides a passively driven type artificial finger used for two degrees of freedom disabled people, which relates to the artificial finger for disabled people. The artificial finger solves the problem that the artificial finger which is applicable to a base finger knuckle residual patient and can be passively driven by two degrees of freedom disabled people does not exist at present. The front end of a link spring support is in rotating connection with a substrate; one end of an upper connecting rod of the base finger knuckle and one end of a lower connecting rod of the base finger knuckle are connected with the substrate; the other end of the upper connecting rod of the base finger knuckle is fixedly connected with the middle part of an upper stop lever of the base finger knuckle; the other end of the lower connecting rod of the base finger knuckle is fixedly connected with the middle part of a lower stop lever of the base finger knuckle; one end of the upper stop lever of the base finger knuckle is fixedly connected with one end of an upper wire stop; one end of the lower stop lever of the base finger knuckle is fixedly connected with one end of a lower wire stop; and the other end of the upper stop lever of the base finger knuckle and the other end of the lower stop lever of the base finger knuckle are connected with a middle finger knuckle framework respectively. The artificial finger realizes three-dimensional motion of the artificial finger in the passively driven mode in two degrees of freedom, namely stretching and laterally swinging, without external power drive, and has the advantages of simple and rapid assembly and personated motion mode.

Description

Technical field [0001] The invention relates to a fake finger for the disabled, in particular to a fake finger for the disabled driven by the disabled finger. Background technique [0002] Functional prosthetic hands are prosthetic limbs that can achieve motion similar to human hands. Now most of the functional prosthetic hands for the disabled use external power driving methods to provide power. The power source involves electric, pneumatic and hydraulic drives. Due to the need to integrate the power source into the prosthetic hand, the prosthetic hand is too large, which is only suitable for the disabled with all palms. The narrow application area cannot meet the needs, and the application range is limited. At present, the more successful commercial functional prostheses require disabled persons to have full palm disability, and even the remaining length of the forearm is required not to be too long. According to the survey, some finger disabilities also account for a considera...
