A bionic finger structure

Abstract

The application belongs to the technical field of bionic robots, and particularly relates to a bionic finger structure. The technical scheme is as follows: a bionic finger structure comprises a proximal phalanx, one end of the proximal phalanx is rotationally connected with a middle phalanx, the other end of the middle phalanx is rotationally connected with a distal phalanx, the lower side of the distal phalanx is connected with a distal phalanx steel rope, a middle phalanx pulley is sleeved on the rotation shaft between the middle phalanx and the proximal phalanx, the other end of the distal phalanx steel rope is connected with the proximal phalanx after winding around the upper side of the middle phalanx pulley, and the lower side of the middle phalanx is connected with a middle phalanx steel rope; the end of the proximal phalanx away from the middle phalanx is rotationally connected with a finger cross, the two sides of the finger cross are respectively rotationally connected with a proximal phalanx left pulley and a proximal phalanx right pulley, a cross steel rope is fixed on the proximal phalanx, one section of the cross steel rope is connected with the proximal phalanx left pulley and then wound out from the proximal phalanx left pulley, and the other section of the cross steel rope is connected with the proximal phalanx right pulley and then wound out from the proximal phalanx right pulley. The application provides a bionic finger structure.
