Auxiliary load-bearing device for a detachable handicapped mechanical arm, a handicapped mechanical arm and a method of using the same

Abstract

The invention discloses a detachable auxiliary load-bearing device for a disabled manipulator, comprising a load-bearing arm and a positioning mechanism, the load-bearing arm is connected to the positioning mechanism, and the load-bearing arm is installed on the disabled manipulator through the positioning mechanism, and the positioning mechanism and the handicapped manipulator It is a detachable connection; the load-bearing arm includes a working push rod, an auxiliary hook and a lifting drive mechanism for driving the working push rod to reciprocate along the axial direction of the working push rod itself, and the auxiliary hook is arranged on the working push rod At the bottom end, the auxiliary hook is used to hook heavy objects that need to be extracted. The invention also discloses a disabled-assisting mechanical arm, which includes an arm body and the above-mentioned detachable auxiliary load-bearing device of the disabled-assisting robotic arm. The invention also discloses a method for using the above-mentioned disability-assisting mechanical arm, which can realize the installation and disassembly of the auxiliary load-bearing device, and is beneficial for lifting heavy objects. The invention can meet the requirement of people who use the disabled manipulator to extract heavy objects.

Description

technical field [0001] The invention belongs to the technical field of assisting the disabled, and in particular relates to a detachable auxiliary load-bearing device for assisting the disabled, a robotic arm for assisting the disabled and a use method thereof. Background technique [0002] Physical disabilities will cause great troubles to people's lives. In order to meet the needs of disabled people for self-care, there is a wide demand for handicapped robotic arms. At present, there are some handicapped robotic arms on the market with light mechanical structures, and most of them can meet the corresponding basic functions. [0003] For example, the patent application with the publication number CN106963524A discloses a 3D printed myoelectric bionic prosthetic arm, which includes an upper arm, a forearm, an elbow joint and a palm. The upper arm is connected to the forearm through the elbow joint. The motor and the bending motor that drives the forearm to bend, and the top ...

AI Technical Summary

Problems solved by technology

The 3D printed myoelectric bionic prosthetic arm can help people with disabilities complete basic arm functions, but like some existing robotic arms for assisting the disabled, it has poor load-bearing capacity for picking and placing relatively heavy objects, and forcible extraction will cause the arms to lose weight. The joints of segments and joints are "strained", which reduces the service life of prosthetic arms or robotic arms for the disabled
