[0002] At present, prosthetic hands with independent driving mechanisms for each finger are called bionic hands at home and abroad. Although a lot of research has been done on this prosthetic hand at home and abroad, only in recent years have two structures reached a practical level and entered the world prosthetic product market. , so that the five fingers of prosthetic hand products have been driven by only one motor for a long time.

Embodiment Construction

[0018] In order to understand the technical content of the present invention more clearly, the following examples are given in detail. The five fingers of the bionic hand must be able to move independently, and each finger must have an independent driving mechanism. The five fingers are different in length and thickness, but the driving principle can be the same. Now illustrate its structural features with a finger. figure 1 It is a schematic diagram of the specific implementation of the driving structure of the fingers of the two-knuckle bionic prosthetic hand of the present invention; figure 2 A schematic diagram of the specific implementation of the driving structure of the fingers of the three-knuckle bionic prosthetic hand of the present invention; image 3 It is an outline drawing of the driving structure of the fingers of the two-knuckle bionic artificial hand of the present invention. In the drawings of the driving structure of the fingers of the bionic prosthetic h...

Abstract

The invention relates to an artificial finger driving structure. An artificial finger comprises an artificial finger driver, two or three knuckles and a transmission mechanism, wherein the artificial finger transmission driver is arranged in an artificial palm, and a power output wheel thereof is fixed together with the lower end of the first knuckle; the lower end of the second knuckle is connected with the upper end of the first knuckle by a pulley shaft; a pulley is arranged on the pulley shaft and fixed together with the lower end of the second knuckle; a fixed wheel is fixed together with a driver outer casing and is concentric with the power output shaft; a rope is arranged on the fixed wheel and the pulley in a 8 shape and fixed by one point respectively with the two wheels. If the artificial finger has the movable third knuckle, the second knuckle drives the first knuckle by the structure. The invention has particular and skillful design, the joints of the artificial finger can extend and contract together, the transmission efficiency is high, and the torque and speed of the joints in different position are same. The invention has the advantages of simple and reliable structure, light weight, small volume, good property and convenient use and is suitable for popularization and application in a large scale.

Description

technical field [0001] The invention relates to the technical field of prosthetic hands, in particular to the technical field of bionic prosthetic hands, in particular to a driving structure of a bionic finger. Background technique [0002] At present, prosthetic hands with independent driving mechanisms for each finger are called bionic hands at home and abroad. Although a lot of research has been done on this prosthetic hand at home and abroad, only in recent years have two structures reached a practical level and entered the world prosthetic product market. , so that the five fingers of prosthetic hand products have been driven by only one motor for a long time. The first is the I-Limb product of the British Touch Bionics company that was launched first, and the other is the Bebionichand product of the RSLSteeper company that was launched later. [0003] The structure of each joint of the artificial finger is one of the main technical difficulties of the bionic hand in a...
