Abstract

The invention relates to an old and disabled-assistant bed chair integrated robot. According to the old and disabled-assistant bed chair integrated robot, internally and externally-nested stair climbing wheels are fixed on two base plate arc-shaped racks; a base plate seat module is connected with a chair support module and can slide along the base plate arc-shaped racks; upper arc-shaped slideways are fixed on a base plate support module; a movable backrest and a movable seat are connected with chair support module by a hinge; a control handle can be inserted into slots on the chair support module and movable handrails; and a shank support plate is connected with the movable seat by the hinge and can slide along arc-shaped slideways of the shank support plate on inner sides of the upper arc-shaped slideways. According to the old and disabled-assistant bed chair integrated robot, the robot has combined functions of ascending and descend the stairs, assisting in standing, converting a chair and assisting in toileting; when the robot meets steps, loading wheels in tires lifts the wheels by taking recesses of outer tires as pivots, and the relative motion of the main modules of the robot is combined to prevent the robot from tilting; the arc-shaped racks slip off along the arc-shaped slideways to assist users in standing by rotating the movable handrails at the tail ends of the arc-shaped racks; and the components are unfolded to form a bed, and are controlled by using the wired or wireless control handle.

Description

technical field

[0001] The invention relates to the field of health care equipment, in particular to an integrated bed and chair robot for helping the elderly and the disabled with the functions of going up and down stairs, assisting standing, bed and chair conversion, and assisting going to the toilet. technical background

[0002] In recent years, with the development of society and the intensification of population aging, many universities, companies and research institutions at home and abroad have conducted in-depth research on robots for the elderly and the disabled, and proposed their own products or solutions. Equipment for helping the elderly and the disabled can be divided into three categories: stair-climbing wheelchairs, integrated nursing beds with beds and chairs, and sports assistance or rehabilitation robots.

[0003] There are many types of stair-climbing wheelchairs. Planetary wheel and crawler-type stair-climbing mechanisms are generally used. When going u...
