Multifunctional auxiliary robot for leg-free disabled person to drive or get on and off

Abstract

The invention relates to the field of medical instruments, and especially relates to a multifunctional auxiliary robot for a leg-free disabled person to drive or get on and off. The multifunctional auxiliary robot comprises a movable seat and a seat guide rail assembly; the seat guide rail assembly comprises an in-vehicle supporting frame installed on an in-vehicle bottom plate and an exposed supporting frame folded into a vehicle when not used; andthe movable seat comprises a seat body, a multi-degree-of-freedom supporting structure and a chassis which are sequentially connected from top tobottom, a rolling assembly in rolling fit with the exposed supporting frame and the in-vehicle supporting frame is arranged on the chassis, a power unit for driving the rolling assembly to roll is arranged on the chassis, and the multi-degree-of-freedom supporting structure is arranged to be of a deformable structure and is used for adjusting the pose of the seat body. The multifunctional auxiliary robot is convenient for a user with leg handicap to comfortably get on and off a compartment; and the movable seat has a multi-degree-of-freedom adjusting function, so that the riding comfort is guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a robot that assists disabled people to get on and off the bus. Background technique [0002] With the development of computer technology, especially the breakthroughs in intelligence and logic, wheelchairs have begun to get rid of the shackles of traditional pure machinery and powered by human arms. Under the mutual induction of vehicle sensors and wheelchair sensors, wheelchairs can be easily realized. It is docked with the vehicle track to complete the action of getting on and off the wheelchair, and the wheelchair adopts a Z-shaped structure as the main part of the wheelchair. Taking advantage of its structural characteristics of easy stretching, combined with a balance sensing device, and using a servo motor as power, the passenger seat can be adjusted at any time The seat is in a horizontal position all the time, and the height in the vertical direction can be adjusted accord...

Problems solved by technology

In the field of medical equipment, our country started relatively late, and the same is true in the field of driving assistance robots for the legless disabled. The motion control system is integrated to ensure the stability of motion and positioning accuracy. However, it is difficult to overcome the problem of the occupant and the wheelchair entering the compartment at the same time and ensuring the convenience of the occupant when designing the wheelchair. As a result, the movement mode of this type of wheelchair is single, and it is difficult to integrate people and wheelchairs. in and out
