Embodiment Construction

[0035] Such as figure 1 The humanoid prosthetic hand based on the coupling link of the present embodiment includes a wrist 2, a palm 3 connected with the wrist 2 to carry and fix five fingers, a finger 4, and a control system 1 that provides power and control signals for the prosthetic hand.

[0036] Such as figure 2Wrist 2 includes a disc-shaped base 201, a palm fixed disc 202, a connecting shaft 203 connecting the disc-shaped base and the palm fixed disc, a servo motor fixed in the disc-shaped base, a crank is assembled on the servo motor, and the crank and the palm fixed disc are connected 202 of the connecting rod 204 .

[0037] Such as image 3 , the palm is set above the wrist, including the front face 301 and the back face 303, five groups of finger fixing holes 304 are arranged on the back face, and five groups of finger fixing holes 304 are arranged on the front face corresponding to the same size and shape. The grooves, the grooves and the finger fixing holes 304...

Abstract

The humanoid artificial hand disclosed by the present invention comprises a wrist (2), fingers (4), a palm (3) connected with the wrist (2) to carry and fix the fingers, and a control system (1) for providing power and control signals for the artificial hand; The grasping method with one degree of freedom for each finger is adopted, and the six-link coupling mechanism of the fingers is used to simulate the bending action of the fingers, so that the opening and closing speed of the fingers is fast, and the grasping process is closer to the human hand; the control system of the prosthetic hand is integrated into the interior of the prosthetic hand , the sensor system is embedded inside the finger mechanism, realizing the mechatronics design of the prosthetic hand, making the prosthetic hand small in size and light in weight.

Description

technical field [0001] The invention relates to the technical field of hand prosthesis. Background technique [0002] With the continuous development of science and technology and people's increasing attention to the welfare of the disabled, prosthetic hands for the disabled based on various principles have appeared one after another. These include the most widely used German Otto Bock single-free prosthetic hand, the Stanford University prosthetic hand with rope actuation, the Spanish Manus prosthetic hand with tendon actuation, the Italian ARTS laboratory prosthetic hand, the University of Southampton prosthetic hand with under-actuated technology and Shikoku Jointly developed CyberHand et al. [0003] The TBM prosthetic hand of the University of Toronto uses a linkage mechanism and is an experimental multi-fingered prosthetic hand designed for children aged 7 to 11. The four fingers (index finger, middle finger, ring finger and little finger) have three knuckles respect...
