Power-assisted chair driven and lifted compoundly by hydraulic screw

Abstract

The invention discloses a power-assisted chair driven and lifted compoundly by hydraulic screw. The power-assisted chair comprises a backrest mechanism, a seat mechanism, a backrest mechanism drive motor, a foot pedal assist mechanism drive motor, a hydraulic screw compound lifting device, a chair frame, a foot pedal assist mechanism, a brake mechanism, rear support wheels and guide wheels, and the backrest mechanism and the seat mechanism are arranged on the upper part of the chair frame; the middle part of the chair frame is provided with the hydraulic screw compound lifting device, the hydraulic screw compound lifting device is composed of a hydraulic cylinder, a screw, a drive motor and a pulley, and the upper part of the hydraulic screw compound lifting device is connected with the seat mechanism through the pulley by a sliding pair; the foot pedal assist mechanism and the seat mechanism are connected by a cylindrical pair; the rear support wheels are arranged on both sides of therear part of the lower end of the chair frame; the brake mechanism and the the chair frame are connected by a cylindrical pair; and the guide wheel mechanism is arranged at the front part of the lower end of the chair frame. According to the present invention, users can be assisted to stand slowly, automatic brake when riding can be realized, and detection and feedback of the physical conditionsof the users can also be performed.

Description

technical field [0001] The invention relates to the field of booster chairs, in particular to a booster chair driven up and down by a hydraulic screw. Background technique [0002] It is understood that thousands of people lose the ability to walk every year due to various accidents. At the same time, as the aging of society continues to increase, the elderly will also experience inconvenience in their movements. Therefore, the use of booster chairs The total number of people with reduced mobility is very high. Usually, people in better condition need to rely on booster chairs to move, but for people who ride booster chairs, sitting in a sitting position for a long time, lack of standing and walking for a long time will easily lead to leg muscle atrophy, which is not conducive to the health of the occupants , so while the booster chair is used as a means of transportation for people with disabilities, it also requires the occupant to get up in a timely manner to carry out p...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems described in the background technology, to provide a power-assisted chair that is driven up and down by a hydraulic lead screw; Get up slowly to solve the problem that people with reduced mobility need to be accompanied by others at all times. At the same time, it can realize the function of automatic braking when the occupant is riding, and can also use sensors to detect and give feedback on the physical condition of the occupant in real time.
