Back extrusion preventing and two-wing extending device of intelligent electric wheelchair bed

Abstract

The invention discloses a back extrusion preventing and two-wing extending device of an intelligent electric wheelchair bed. The back extrusion preventing and two-wing extending device comprises a back extending plate, two-wing extending plates, a floating back plate, a connecting rod drive mechanism, a connector, a rising pillow, a hinge part, a seat plate and an elastic soft curtain. The connecting rod drive mechanism is composed of an electric push rod, connecting rods and auxiliary connecting rods, one end of the connecting rod drive mechanism is fixed to the seat plate, and the other end of the connecting rod drive mechanism is connected with the back extending plate and the two-wing extending plates. According to the back extrusion preventing and two-wing extending device of the intelligent electric wheelchair bed, ergonomic design is adopted, when a bed posture and a sitting posture are switched, a user is in a comfortable state all the time, the angle between the user and the floating back plate is automatically adjusted, no friction effect is caused to the user, damage to the organism is avoided, electricity is adopted as power, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to an intelligent electric wheelchair bed, in particular to an anti-extrusion back and two-wing stretching device of the intelligent electric wheelchair bed. Background technique [0002] Guarantee and improve the quality of life of vulnerable groups such as the elderly and the disabled, and effectively enhance the mobility of the elderly and the disabled, which not only makes their daily life more convenient, but also improves their mental health, self-evaluation, and mental state. has far-reaching consequences. Intelligent electric wheelchair bed is not only a means of transportation for the elderly and disabled people with poor self-care ability, but also a necessity of life, assisting them to complete their daily life within their ability. [0003] Existing electric wheelchair beds often have a simple structure and a single function. When the electric wheelchair bed gets up (turning the back), due to the joint action of the b...

Problems solved by technology

[0003] Existing electric wheelchair beds often have a simple structure and a single function. When the electric wheelchair bed gets up (turning the back), due to the joint action of the back friction force and the angle of the back seat, it gives people a kind of resistance and makes the user feel uncomfortable. Especially when the disabled person uses it, since the posture cannot be self-corrected with the lifting of the back seat, it is easy to cause damage to the body
