Abstract

A bionic mechanical arm comprises a first shoulder joint shaft, a second shoulder joint shaft, a first elbow joint shaft and a second elbow joint shaft; a first shoulder joint shaft nylon roller rotating horizontally is connected at the lower part of the first shoulder joint shaft; first guide wheels moving downwards are arranged on two sides of the first shoulder joint shaft nylon roller; the second shoulder joint shaft is arranged below the first guide wheels; two vertical second shoulder joint shaft nylon rollers are arranged on the second shoulder joint shaft; and a first shoulder joint shaft steel wire is connected among the first shoulder joint shaft nylon roller, the first guide wheels and the second shoulder joint shaft nylon rollers. The bionic mechanical arm has the beneficial effects as follows: the bionic mechanical arm is high in space utilization rate, compact in structure, attractive in appearance, easy to control, high in pose accuracy and convenient to connect, the nylon rollers and the steel wires are adopted on the mechanical arm structure, the size and the weight of a transmission system are reduced, the transmission sound is small, the price is relatively low, and the freedom degree required by movement is guaranteed.

Description

technical field

[0001] The patent of the invention relates to the technical field of bionic prosthesis, and belongs to a bionic mechanical arm. Background technique

[0002] Prosthetic limbs are artificial limbs manufactured and assembled to restore the shape and function of the human body and to compensate for the defects caused by amputation. Installing prosthetic limbs is an important means for amputees to recover and return to society. The structural design of the bionic robotic arm is a key component in the design of prosthetics. The volume, weight, appearance, and freedom of movement of the bionic robotic arm are all determined by the structural design of the robotic arm. The bionic manipulator requires small size, light weight, beautiful appearance, and can complete as many actions as possible that people first want to achieve. However, if it is required to be small in size and light in weight, its motion function will be limited. If the movement function is requir...
