Embodiment 1

[0034] Refer to Figure 1 to Figure 4 , This embodiment discloses a seat assisting sitting, including a support assembly 1, a seat assembly 2, a lifting assembly 3, and an electric control assembly. The seat assembly 2 is symmetrically fixed to the lifting assembly 3 on both sides of the support assembly 1. Fixed on the support assembly 1, the seat assembly 2 is provided with an electric control assembly, and the electric control assemblies are electrically connected to the support assembly 1, the lifting assembly 2 and the seat assembly 3; the seat assembly 2 is controlled by the lifting assembly 3 when sitting down Ascend to a high position to assist the elderly to sit on the seat, and then lower to a low position, and when getting up, the seat assembly 2 is controlled to rise by the lifting assembly 3 to send the elderly to the high position and then get up again, which solves the problem of the elderly sitting The problem of instability of the center of gravity caused by ge...

Embodiment 2

[0047] Refer to Figure 5 In this embodiment, on the basis of the first embodiment, the rear leg 13 is a hollow cylinder with an open upper end, and the upper end of the rear leg 13 is provided with an adjustable support structure 15 capable of supporting the seat plate 21. The structure 15 realizes the support for the seat assembly 2 in the low position, prevents the seat assembly 2 from overwhelming and toppling when in the low position, ensures the stability of the seat assembly 2, and further reduces potential safety hazards.

[0048] The adjustable support structure 15 includes a nut 151, a screw 152, a support block 153, and a gravity sensor 154. The nut 151 is fixed on the upper end of the rear leg, and the center of the nut 151 is the same vertical as the center of the rear leg 13 On the line, one end of the screw 152 is fitted with the internal thread of the nut 151 and penetrates the nut 151 to extend into the rear leg 13, and the other end is fixed with a support block ...

Embodiment 3

[0051] Refer to Image 6 In this embodiment, on the basis of the second embodiment, the bracket 11 is a square frame structure that penetrates back and forth, and the seat plate 21 is provided with a vertically through stepped hole 211, and the upper surface of the stepped hole 211 is provided with a cover The upper surface of the cover plate 212 is flush with the upper surface of the seat plate 21; specifically, when the elderly need to go to the toilet, since the bracket 11 is a square frame structure that penetrates back and forth, the seat can be moved directly to the seat The upper end of the toilet can go directly to the toilet by removing the cover 212. For the elderly and people with inconvenient legs, they can go to the toilet without having to go to the seat or sitting on the toilet, which is convenient for the elderly and people with inconvenient legs. Daily life.

Abstract

The invention discloses a seat assisting in sitting and standing. The seat comprises a supporting assembly, a seat assembly, lifting assemblies and an electric control assembly, wherein the seat assembly is fixed to the supporting assembly through the lifting assemblies symmetrically fixed to the two sides of the supporting assembly; the electric control assembly is arranged on the seat assembly;the electric control assembly is electrically connected with the supporting assembly, the lifting assemblies and the seat assembly; the supporting assembly comprises a support, a front supporting legand a rear supporting leg; and the seat assembly comprises a seat plate, a backrest, a first armrest, a second armrest, a rotating motor, a spiral bevel gear and an arc-shaped baffle. The seat has theadvantages that the seat not only solves the problem of unstable gravity centers caused by sitting down and getting up of old people, can assist the old people in sitting and standing, so that the old people are prevented from falling down, but also the seat is suitable for other people with inconvenient legs and feet, and meanwhile, defecation behaviors of the old people and the people with inconvenient legs and feet are facilitated.

Description

Technical field [0001] The invention relates to the technical field of seats, in particular to a seat assisting sitting and standing. Background technique [0002] With the increasing aging, the number of elderly people is increasing. In 2012, the elderly population over the age of 65 in my country has reached 127 million, and it is still increasing at a rate of 8 million every year. Experts predict that by 2050, the elderly population in my country will be Reach one-third of the total population. With the increase of age, the elderly are insufficiently active and inconvenient to go out. The elderly at home often sit on chairs. However, due to poor physical balance and poor physical fitness of the elderly, they are prone to fall when sitting on existing seats, and quickly stand up after sitting for a long time, which can easily induce transient cerebral ischemia, dizziness and vertigo. It is also prone to accidents such as falls and injuries, which poses great safety hazards. S...
