Novel wheelchair bed integrating bed and chair

Abstract

The invention discloses a novel wheelchair bed integrating a bed and a chair. The novel wheelchair bed comprises a wheelchair bed body, wherein the wheelchair bed body comprises a wheelchair bed frame, the wheelchair bed frame is composed of a base frame, a seat plate body, a back plate body and a leg plate body, and the novel wheelchair bed further comprises an expanding seat plate folding and supporting device and a back plate folding, expanding and supporting device. The back plate folding, expanding and supporting device is composed of a second electric push rod, a back plate expanding device and a back plate folding and supporting device; The novel wheelchair bed further comprises a leg plate folding, expanding and supporting device which is composed of a linear guide rail, a leg plate expanding device and a leg plate folding and supporting device. The novel wheelchair bed integrating the bed and the chair combines the postures and functions of a nursing bed and a wheelchair so that the nursing bed and the wheelchair are truly integrated, multifunctional, modular and intelligent, and automatic bed-chair interchange is realized, and the novel wheelchair bed integrating the bedand the chair is high in economy, high in flexibility and high in reliability.

Description

technical field [0001] The invention relates to the related technical field of medical rehabilitation auxiliary equipment for nursing beds, in particular to a novel wheelchair bed with integrated bed and chair. Background technique [0002] According to the statistics of the National Bureau of Statistics, as of 2019, the total number of elderly people aged 60 and over in my country has reached 253.88 million. The base of the elderly population is huge, accounting for about 18.1% of the total population. 11.9% of the total population. According to predictions, by 2053, the elderly population will grow to a peak of about 487 million, accounting for 34.9% of the total population at that time, and my country will become a super-aged country. [0003] As of 2019, the number of disabled or semi-disabled people in my country has reached 85 million, accounting for about 6% of the total population; it can be seen that the large number of elderly people, disabled and semi-disabled peo...

Problems solved by technology

[0009] The purpose of the present invention is to provide a new type of wheelchair bed integrated with a bed and chair to solve the problem that the backboard and leg boards of existing ordinary wheelchairs can have a certain tilting angle. Insufficient support, low reliability, it is difficult for the user to lie flat, and it is necessary to provide reliable ground support for the backboard and leg boards;

[0010] Solve the problem that the legs, seat, and back of the existing ordinary wheelchairs are narrow in width. It is difficult for the user to turn over when lying on the wheelchair with the backboard flat, and the comfort is poor. To transform into a nursing bed posture, it is necessary to widen the legs and seat of the wheelchair. The width of the head and back, that is, the problem of widening the overall chair surface area to become the bed surface;

[0011] To solve the existing common methods of widening the legs, seat and back, directly widen the width of the legs, seat and back, resulting in a large and bulky wheelchair bed as a whole, and inconvenient movement; to solve the problem of increasing the width of the backboard through manual docking expansion, However, this method is inaccurate and easy to damage, the workload is large and impractical, and it is difficult to realize automation;

[0013] The current common method of supporting the backboard is to add a support device behind the wheelchair frame. However, this method is inconvenient to install and takes up a lot of space, resulting in the problem that the overall length of the wheelchair is too long and the mobility is poor; The transmission of the support device, however, the number of original moving parts in this method is too large, the installation is inconvenient, and the price is expensive
