Exoskeleton mechanical auxiliary hand

Abstract

The invention discloses an exoskeleton mechanical auxiliary hand. The exoskeleton mechanical auxiliary hand comprises a mechanical structure part and a power part, wherein the mechanical structure part comprises a plastic wrist sleeve, a palm profiling plastic housing, finger joint plastic finger sleeves and linkage structures, the palm profiling plastic housing and the finger joint plastic fingersleeves are arranged by profiling one complete palm, the linkage structures are arranged on the back surfaces of the palm profiling plastic housing and the finger joint plastic finger sleeves; the plastic wrist sleeve is connected with the palm profiling plastic housing; the power part comprises a steering engine and pressure sensors; the steering engine is arranged on the back surface of the palm profiling plastic housing and is connected with the linkage structures; the pressure sensors are arranged at the fingertip parts of the finger joint plastic finger sleeves; and the steering engine and the pressure sensors are electrically connected to a single chip microcomputer control system. The exoskeleton mechanical auxiliary hand is light and easy to carry, and can meet the requirements ofdaily auxiliary training of a large number of patients with impaired hand functions.

Description

technical field [0001] The invention relates to a manipulator device, which belongs to the field of machinery and control, in particular to an exoskeleton mechanical auxiliary hand. Background technique [0002] For patients with hand diseases, including accidental injuries, strokes, etc., scientific rehabilitation training is of great significance for the maximum recovery of hand flexibility. [0003] An exoskeleton is a rigid external structure that provides configuration, architecture, and protection to the soft internal organs of living things. Generally, the tough chitin skeleton on the body surface of arthropods such as shrimps, crabs, and insects is called exoskeleton, which has protective and supporting functions. The mechanical exoskeleton is a brand-new technology derived from the biological exoskeleton. As a way to strengthen the human body through machinery, it has been proposed as early as the last century and was initially tried to be used in the military fiel...
