Abstract

The invention provides a motor built-in type high-imitation coupled thumb for a handicapped artificial hand, and relates to coupled thumbs. The thumb in existing artificial hand has the defects of complicated structure, large occupied space, insufficient shape and moving function and inflexible action. The coupled thumb comprises a metacarpophalangeal joint, a proximal joint, a distal joint, a motor component, a circuit board component and a sensor component, wherein the proximal joint is arranged on the metacarpophalangeal joint, and the distal joint is arranged on the proximal joint; the motor component is arranged in the proximal joint; the circuit board component and the sensor component are arranged in the distal joint; the motor component enables the proximal joint to rotate around the metacarpophalangeal joint with a mounting seat under control of the circuit board; and the sensor component is fixedly arranged at the finger prominence end of the distal joint. Due to the arrangement of the built-in motor component, the coupled thumb has the advantages of simple integral structure and small occupied space, the integral structure and function can approach a real human thumb due to the cooperation of the proximal joint, the distal joint, the circuit board component and the sensor component. The motor built-in type high-imitation coupled thumb is applicable to an intelligent robot.

Description

technical field [0001] The invention specifically relates to a motor-built-in high imitation coupled thumb for a handicap's prosthetic hand. Background technique [0002] The hand is the most complex and delicate tool for human survival and labor. Human beings can use their hands to contact the external environment and obtain information from the environment to better operate the environment. As an important content and component of rehabilitation medical engineering, prosthetic hand is an important means to make disabled people recover and return to society. The structure of the thumb in the existing prosthetic hand is complicated and takes up a lot of space. Its structure and working principle are manufactured by the same method as in the robot finger, and the design of the middle knuckle is still retained, which does not conform to the structure of the real human thumb. The grasping, holding or other actions made by the fingers cannot reach the standard and flexibility o...
