Auxiliary standing device

Abstract

The invention provides an auxiliary standing device, which comprises a support frame, a seat frame, a backrest frame, a leg supporting frame, a pedal frame, a first connecting rod mechanism, a second connecting rod mechanism and a third connecting rod mechanism, wherein the two ends of the seat frame are hinged to the leg supporting frame and the backrest frame; the pedal frame can vertically move along the leg supporting frame; a seat cushion is fixed on the seat frame; a backrest cushion is arranged on the backrest frame; the backrest cushion can vertically slide along the backrest frame; a first driving element is arranged between the support frame and the seat cushion and drives the seat frame to act; a second driving element is arranged between the seat frame and the backrest frame and drives the backrest frame to rotate relative to the seat frame; the first connecting rod mechanism is connected between the support frame and the leg supporting frame; the second connecting rod mechanism is connected between the support frame and the seat frame; and the third connecting rod mechanism is connected between the seat frame and the backrest cushion. Through the first driving element, the second driving element, the first connecting rod mechanism, the second connecting rod mechanism and the third connecting rod mechanism, the auxiliary standing device can help people with lower limb dysfunction to perform nursing and rehabilitation training; and the conversion from the sitting posture to the standing posture is realized.

Description

technical field [0001] The present invention relates to an auxiliary standing device, in particular to such an auxiliary standing device, which can help people with lower limb dysfunction to perform nursing and rehabilitation training such as auxiliary standing, and realize the transition from a sitting posture to a standing posture. During the conversion process, relative movement between the user's back and the backrest, and between the buttocks and the seat cushion can be avoided. It belongs to the technical field of rehabilitation aids. Background technique [0002] At present, there are more than 80 million disabled people and nearly 40 million disabled elderly in my country's population. A considerable part of these disabled and disabled elderly people need to use assistive devices to assist them in their daily life. Among them, for disabled and disabled elderly who have weak lower limb muscles and cannot stand independently, auxiliary standing devices can better help...

AI Technical Summary

Problems solved by technology

[0003] Existing assisted standing devices, such as assisted standing seats and standing wheelchairs, are mostly single-pivot devices. And in fact, the bending of the knee joint is not a simple rotation around the axis, but a more complex combination of rotation and sliding. Therefore, when the auxiliary standing device is converted from a sitting position to a standing position, it will cause the user's back Relative movement with the backrest of the device, the user's buttocks and the cushion of the device

However, this relative movement is undesirable, exacerbates user discomfort, and creates a shear force between the device and the user's body that can exacerbate pressure sores in users who remain in a sitting or lying position for extended periods of time. happened
