Width adjustable holding flexible arm mechanism for self-recover nursing robot

Abstract

The invention discloses a width adjustable holding flexible arm mechanism for a self-recover nursing robot. The holding flexible arm mechanism comprises a motor, a worm wheel, a worm, a left wire wheel, a left adjusting sliding block, a left fixing guide rail, a worm wheel fixing shaft, a left wire wheel shaft, left pulling rope guiding wheels, a left synchronous belt wheel, left pulling ropes, left limiting blocks, a synchronous belt, a first synchronous gear, a second synchronous gear, a transmission shaft, a right synchronous belt wheel, a right wire wheel, a right adjusting sliding block, a left fixing guide rail, a right wire wheel shaft, right pulling rope guiding wheels, right pulling ropes, right limiting blocks, a chest backer, left spring plates, flexible arm limiting pressing blocks and right spring plates. The holding flexible arm mechanism has the rolling recovery function of the holding and self-recover states during operation, rotation of the motor is transformed into rotation of the two wire wheels at the same speed in the opposite directions through the worm wheel, the worm, the synchronous belt wheels and the synchronous gears, and thus the telescoping function of the pulling ropes is transformed into the rolling holding and recovery actions of the holding arm. The holding flexible arm mechanism is simple in structure and compact and adjustable in width.

Description

technical field [0001] The invention relates to the field of intelligent nursing robots, in particular to a human-embracing flexible arm mechanism for a self-recovering nursing robot with adjustable width. Background technique [0002] With the continuous development of society, the aging degree of the world's population is gradually increasing, and the number of semi-disabled elderly people is also gradually increasing, and the daily living difficulties of the semi-disabled elderly people are increasing. Humans create a huge workload, hence the need for nursing robots. The robot can safely pick up the care recipient from the wheelchair (sofa or bed) autonomously and move it to the bedside, toilet or other locations, so the soft arm mechanism of the robot is very important. Application No. 201410649799.7 discloses a robot with a flexible arm, which can bend freely and hold objects, but its structure is complicated, and it does not have the function of adjusting the width of...

Application No. 201410649799.7 discloses a robot with a flexible arm, which can bend freely and hold objects, but its structure is complicated, and it does not have the function of adjusting the width of the flexible arm, so it cannot adapt to people of different sizes. The soft arm stretches out all the time and takes up a lot of space
