Description

TECHNICAL FIELD

[0001] The utility model relates to an electric control lifting and standing device and belongs to the technical field of rehabilitation training equipment. BACKGROUND

[0002] The increasing trend of population aging leads to an increasing number of patients with lower extremity motor dysfunction, and these patients urgently need effective rehabilitation training to restore the lower extremity motor function. At present, the commonly used lower extremity rehabilitation equipment is an electric rehabilitation training bed, which mainly serves to improve the blood circulation of patients with lower extremity dysfunction, enhance the strength of lower extremity muscles, prevent muscle atrophy and pressure sores caused by long-term bed rest, stimulate the nervous system of patients, and restore the control ability of the nervous system on muscles, thereby laying a good foundation for subsequent gait training.

[0003] For patients with lower extremity motor dysfunction, especially those in the bedridden period, the rehabilitation training bed needs to be adjusted in height to match the stretcher bed and hospital bed, and to assist the patient in completing the supine position to the standing position. Therefore, a lifting and standing mechanism needs to be provided at the bottom of the rehabilitation training bed. The existing lifting and standing mechanisms mainly include a scissors mechanism with intersecting support rods and a quadrilateral structure with parallel rods.

[0004] The existing parallelogram structure lifting and standing device has the following defects:

[0005] 1. Poor structural stability: The top rod of the driving assembly is connected to the fixed rod in a vertical direction. Since this structure bears two components from the horizontal and vertical directions, there is a large stress concentration phenomenon at the connection between the top rod of the driving assembly and the fixed rod, and therefore the stability and safety of this connection structure are weak.

[0006] 2. Limited bed frame movement: The existing technology does not design the lifting and standing movements of the bed frame to be coupled, so when the bed frame is lowered to the lowest position, the end of the bed frame may collide with the ground when it is raised to a certain angle, and therefore the maximum standing angle cannot be reached, resulting in limited bed frame movement and potential safety risks.

[0007] The utility model with the publication number CN211326270U is an electric control lifting device. The top rod and the bottom rod of the utility model always remain horizontal, the stable lifting of the bed frame is realized by changing the inclination angle of the connecting rod, the structure has good stability and consumes less power. However, the top rod and the fixed rod of the utility model are perpendicular to each other, stress is concentrated when the bed frame rotates, the connection is prone to breakage and damage, the foot of the bed frame is close to the ground, and the bed frame may collide with the ground. Therefore, the bed frame needs to be raised to a certain height before it can be rotated, the movement range of the bed frame is limited, and the utility model is not convenient to use.
