Spring type portable mechanical arm for helping disabled people

Abstract

The invention relates to a spring type portable mechanical arm for helping disabled people. The mechanical arm comprises a mounting part and a clamping jaw; the mounting part is arranged on an arm of a user, is provided with a driving device for driving the clamping claw to be opened or closed and is a fixed sleeve which is arranged at the rear end of a forearm; the fixed sleeve is cylindrical and surrounds the forearm; the driving device comprises a movable sleeve and a linkage mechanism; the movable sleeve is rotationally arranged in the fixed sleeve and is arranged at the front end of the forearm; the clamping claw comprises claw bodies which are arranged in a pair; the claw bodies are rotationally arranged on the fixed sleeve and are provided with a linkage part for adjusting the rotation positions of the claw bodies; the linkage mechanism is arranged between the movable sleeve and the linkage part; when the movable sleeve is driven by the front end of the forearm to rotate relative to the fixed sleeve, the linkage mechanism enables the claw bodies to be separated; and when the movable sleeve does not apply the force to the front end of the forearm, the linkage mechanism enables the claw bodies to get close to each other. The invention provides the spring type portable mechanical arm for helping the disabled people. According to the mechanical arm, by adopting the scheme, the clamping jaw is driven to be opened or closed by utilizing the action of the arm, and the mechanical arm is particularly suitable for the disabled people without all fingers or palms on hands.

Description

technical field [0001] The invention relates to a device for assisting the disabled, in particular to a spring-type portable manipulator for assisting the disabled. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. Manipulators were first developed by the United States. The original purpose was to help people swing heavy labor and perform simple repetitive labor, as well as replace people in dangerous environments. With the long-term practical development and technological innovation of manipulator technology, manipulators are widely used in domestic and foreign industrial manufacturing, military, entertainment, medical and other technical fields due to their accuracy and outstanding ability to complete tasks in various environments. [0003] Although the development of manipulator technology is advancing by l...

AI Technical Summary

Problems solved by technology

The existing manipulator includes a mounting part installed on the human arm. The mounting part is provided with clamping claws, which can be opened or closed to replace similar grasping and some simple actions. On the one hand, the traditional clamping The action of opening or closing the claws is driven by a motor. The motor has disadvantages such as heavy weight and the need for repeated charging. Since the manipulator needs to be carried for a long time, the heavy weight will cause a burden to the user, and the shortcomings of repeated charging will also bring many problems to the user. Limitation, even if the battery can be disassembled and replaced in time, it will also increase the cost of use for the user
