Problems solved by technology

"This invention is used for ordinary chairs. It uses cylinders to realize the function of changing the inclination of the back of the chair or the seat in several steps. It cannot complete the action in a short time when the biped walking chair falls down, so it cannot be used for biped walking chairs. superior
In further literature search, in the field of manned biped walking chair robot, no report identical or similar to the subject of the present invention has been found at present

Abstract

The safety protector for walking chair robot has control system set in the chair back and chair driving system set between the seat and the legs. The control system consists of control box, integrated control unit, tilt angle sensor and control button; and the chair driving system consists of guide canal, connector, main shaft, harmonic reducer, DC motor, bearing, electromagnetic bayonet lock system and pinhole. The robot may protect the sitter from being damaged in case the robot tumble.

Description

technical field [0001] The invention relates to a safety protection device in the field of robots, in particular to a safety protection device for a walking chair robot. Background technique [0002] Disability of the lower limbs has many inconveniences. Although the appearance of wheelchairs has broadened the scope of activities of the disabled to a certain extent, there are still many shortcomings, such as greater energy consumption and inconvenience in going up stairs. For this reason, the idea of ​​designing a bipedal walking chair system is proposed. However, the bipedal walking chair system itself is not stable enough. During the walking process, due to complex road conditions, bumping into things, and mistakes in the walking control algorithm, the bipedal walking chair system may fall down, endangering the safety of the occupants. [0003] After searching the existing technical documents, it was found that the application number: 96197138.X, the title of the inventio...
