Auxiliary standing-up device

Abstract

The invention relates to an auxiliary standing-up device. The device comprises a standing-up mechanism; the standing-up mechanism comprises a middle plate, a bottom plate, a connecting plate, a push rod, a sliding block piece, a sliding rail piece, a first pulley, a second pulley and a traction piece; the lower surface of the middle plate is fixedly connected with the top end of the connecting plate; the upper surface of the bottom plate is rotatably connected with the bottom end of the connecting plate; a mounting hole is formed in the middle of the middle plate; the sliding rail piece is arranged in the mounting hole and connected with the middle plate; the sliding block piece is slidably connected with the sliding rail piece; one end of the push rod is fixed to the upper surface of the bottom plate, and the other end of the push rod is connected with the connecting rod; the first pulley is fixed to the front end of the middle plate; the second pulley is fixed to the upper surface of the bottom plate; and one end of the traction piece is fixedly connected with the first sliding block, and the other end of the traction piece is mounted around the first pulley and the second pulley in sequence and fixedly connected with the tail end of the middle plate. According to the auxiliary standing-up device disclosed by the invention, controllability of the auxiliary standing-up speed, the turnover degree and the reset speed can be achieved.

Description

technical field [0001] The invention relates to the technical field of stand-up assistance, in particular to a stand-up assist device. Background technique [0002] Orthostatic hypotension is a disease commonly seen in the elderly. It generally manifests as dizziness, blurred vision, and unstable standing after a sudden stand after resting on the back for more than 5 minutes when the body position is changed. And so on a series of symptoms. This disease has brought hidden danger to the safety of the elderly, and in view of this situation, there are also some auxiliary standing products on the market at present, but all have very big deficiency. [0003] The existing auxiliary stand-up device cannot satisfy the controllability of the stand-up speed, the turning degree and the reset speed at the same time. [0004] Moreover, when the existing auxiliary stand-up device realizes the stand-up function, the motion curve of the seat cushion is very rigid, and cannot completely fo...

Problems solved by technology

This disease has brought hidden dangers to the safety of the elderly. In response to this situation, there are currently some auxiliary standing products on the market, but they all have great shortcomings.

[0003] The existing auxiliary standing devices cannot satisfy the controllability of the rising speed, turning degree and reset speed at the same time

[0004] Moreover, when the existing auxiliary stand-up device realizes the stand-up function, the motion curve of the seat cushion is very rigid, and cannot completely follow the trajectory of the buttocks movement when a person gets up, so the contact points between the buttocks and the seat cushion cannot be completely fitted, and the actual use is not comfortable enough; And because this type of product starts immediately after the switch is pressed, it does not consider the leg strength of the elderly, so it is not safe enough
