Service robot used as bed or chair

Abstract

The invention relates to the field of automatic equipment, in particular to a service robot used as a bed or a chair. The service robot comprises a bed body frame and a wheelchair, one side of the bedbody frame is open, the wheelchair and the bed frame are movably clamped, and the wheelchair comprises a horizontal base, wherein walking wheels are arranged at the bottom of the base, a chair seat is arranged on the base, one side of the chair seat and a chair back rack are hinged, the other side of the chair seat and a leg rack on one side are hinged, the other side of the leg rack and one pedal rack are hinged, and the chair seat, the chair back rack, the leg rack and the pedal rack are linked through a four bar mechanism. The service robot is reasonable in structural design; when the wheelchair and a bed body need to be aligned and be in butt joint, a rotating motor drives a gear to rotate to realize automatic rotation positioning for the wheelchair, and the stability and safety of the wheelchair and the bed body are guaranteed; after the wheelchair and the bed body are in butt joint, handrails can be controlled to automatically descend to the position below the plane of the bed body, and after the wheelchair is separated from the bed body, the handrails can ascend again, so that the usage space of the combined bed body is effectively enlarged.

[0002] At present, population aging has become an extremely serious social problem in our country, seriously affecting the development of our society, economy and other aspects. In 2017, there were 240.9 million people aged 60 and above in the national population, accounting for 17.3% of the total population. Among them, the population aged 65 and above is 158.31 million, accounting for 11.4% of the total population. In addition, the number of disabled people in China is also huge, especially the number of physically disabled people has exceeded 20 million. How to make the elderly and disabled people more convenient Carrying out self-care of life has become a problem that needs to be solved in today's society. The Chinese patent No. CN2015106793478 discloses a bed-chair integrated robot that automatically separates and docks, which realizes the automatic separation and docking functions of the wheelchair and the bed body, but in actual production During use, after the wheelchair is docked with the bed body, when the user moves the body on the bed, the walking wheels of the wheelchair are likely to rotate, causing the wheelchair and the bed body to shake, affecting the stability and safety of the bed body, and when the wheelchair is docked After reaching the bed body, the erected wheelchair armrests will hinder the user, reducing the use space of the bed body, and the parts on the surface of the armrest are likely to cause safety hazards to the user. When the elderly and disabled people are using , It is very inconvenient to handle when defecating, and the nursing staff needs to help them from the wheelchair to the toilet. However, many elderly and disabled people cannot get on and off the wheelchair with the support of the nursing staff, which has brought a lot to the nursing staff. troubled
