Adjustable multifunctional wheelchair

Abstract

The invention relates to the technical field of nursing instruments, and discloses an adjustable multifunctional wheelchair which comprises a wheelchair base, wheels, a backrest, a seat cushion and a leg and foot support, the seat cushion is arranged on the wheelchair base, the backrest, the leg and foot support are rotationally connected with the seat cushion, and a gravity center adjusting mechanism and a lifting adjusting mechanism are further arranged on the wheelchair. The gravity center adjusting mechanism comprises a sliding rail supporting plate arranged on the wheelchair base and a pair of sliding rails symmetrically arranged on the sliding rail supporting plate, and the seat cushion is connected to the sliding rails in a sliding mode. The lifting adjusting mechanism comprises four electric push rods, a wheelchair frame is arranged on the upper surface of the wheelchair base, and lifting rods of the four electric push rods are rotationally connected to the wheelchair frame. Compared with the prior art, the gravity center adjusting mechanism and the lifting adjusting mechanism are arranged on the wheelchair, a gravity center can be conveniently adjusted according to needs, the wheelchair is prevented from rolling over, and potential safety hazards of the wheelchair are reduced.

Description

technical field [0001] The invention relates to the technical field of nursing devices, in particular to an adjustable multifunctional wheelchair. Background technique [0002] A wheelchair is a special means of transportation for people with lower limb disabilities. Wheelchairs can be divided into motorized wheelchairs and hand-operated wheelchairs according to the driving mode; hand-operated tricycles can adapt to various roads because of their large wheel diameters, and are mainly used as long-distance transportation tools outdoors, and can be used appropriately Loading and planting goods; it has the characteristics of fast driving speed and labor saving. Motorized wheelchairs are equipped with backrests, armrests and seat belt limits to keep the user's body stable, and have a short-distance hand moving device so that they can be manually moved to a safe or unobstructed traffic location in case of failure. Strong mobility, convenient fuel replenishment, convenient opera...

Problems solved by technology

[0003] With the development of the times and the advancement of science and technology, motorized wheelchairs have been manufactured in various forms in the existing market to meet the needs of the market. However, considering many aspects such as comfort, ease of use, and safety, the existing technology is still There are many technical deficiencies: (1) its backrest, seat cushion and dodging rest of the wheelchair in the prior art can be laid flat and docked with the bed, or the angle between the wheelchair backrest, leg rest and seat cushion can be directly adjusted, but in the process of laying flat, However, due to problems such as shifting of the center of gravity, the wheelchair may roll over, which poses a great safety hazard; (2) the wheelchair has an imbalance of center of gravity during the climbing process, and rollover occurs; (3) when the wheelchair is docked with the bed, Difficult to interface with beds of different heights
